DETAILED DESCRIPTION

The embodiment of the present application discloses a plastic recycling device for processing plastic packaging bottles. The device adopts a fixing mechanism 1, a packaging belt separation mechanism 2 and a pumping and inflation mechanism 3, which can conveniently separate the annular packaging belt wrapped and glued to the bottle body of the plastic bottle. The material strength of the packaging bag and the plastic bottle is quite different, so different methods need to be adopted during the recycling process. After separation, the targeted nature of the recycling process can be improved, thereby improving the recycling effect. At the same time, a cleaning mechanism 4 is adopted. The cleaning mechanism 4 is combined with the fixing mechanism 1 and the pumping and inflation mechanism 3. The surface of the plastic bottle is relatively smooth when it is in an inflated state, with no wrinkles or few wrinkles, so the inner and outer surfaces of the plastic bottle are cleaned, thereby achieving a better cleaning effect.

In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Embodiment 1, referring to Figures 1 to 9, the present invention provides a plastic recycling device for processing plastic packaging bottles, comprising a fixing mechanism 1, a packaging band separation mechanism 2 and a pumping and inflation mechanism 3, wherein the fixing mechanism 1 is used to fix the plastic bottle, the packaging band separation mechanism 2 is used to remove the packaging band from the plastic bottle, the pumping and inflation mechanism 3 is connected to the plastic bottle, the pumping and inflation mechanism 3 is used to fill air into the plastic bottle to expand and smooth the bottle body of the plastic bottle, and is used to extract the air in the plastic bottle to shrink the bottle body of the plastic bottle. When the pumping and inflation mechanism 3 expands the plastic bottle, the packaging band separation mechanism 2 contacts the packaging band and fixes the packaging band, and when the pumping and inflation mechanism 3 shrinks the plastic bottle, the plastic bottle is separated from the packaging band, and the packaging band separation mechanism 2 is actuated to remove the packaging band from the plastic bottle.

Specifically, referring to Fig. 3, Fig. 4 and Fig. 5, the fixing mechanism 1 comprises a fixing base 101, a fixing rod 102 is vertically arranged above the fixing base 101, the diameter of the fixing rod 102 is equal to the inner diameter of the bottle mouth of the plastic bottle, and the plastic bottle can be inserted on the fixing rod 102. When the plastic bottle is plugged and fixed, its bottle mouth faces downward. In order to facilitate the plugging of the plastic bottle, the upper end of the fixing rod 102 is connected to a tapered rod 103, the lower end diameter of the tapered rod 103 is equal to the diameter of the fixing rod 102, and the top diameter of the tapered rod 103 is smaller than the diameter of the fixing rod 102, thereby providing guidance for the plugging of the plastic bottle.

Further, referring to Figures 3, 4 and 5, the lower end of the fixing rod 102 is connected to a sealing rod 104, the sealing rod 104 has the same diameter as the fixing rod 102, a sealing groove 105 is provided on the surface of the sealing rod 104, a sealing ring 106 is provided in the sealing groove 105, the outer diameter of the sealing ring 106 gradually increases from top to bottom, the upper end of the sealing ring 106 is flush with the surface of the fixing rod 102, the lower end diameter of the sealing ring 106 is larger than the diameter of the fixing rod 102, and when the bottle mouth of the plastic bottle is inserted into the sealing ring 106, the plastic bottle can be sealed.

It should be noted that, the sealing of the plastic bottle in this embodiment requires that the bottle mouth of the plastic bottle be kept on the sealing ring 106. Based on this, this embodiment further provides a limit ring 107 on the outer periphery of the sealing rod 104. The limit ring 107 is elliptical and horizontally arranged. The long axis of the limit ring 107 is arranged horizontally. The limit ring 107 has no contact with the fixed rod 102, and the central axis of the limit ring 107 coincides with the axis of the fixed rod 102. A limit groove 108 is provided on the inner wall of the limit ring 107, and two limit slides 109 are slidably arranged in the limit groove 108.

At the same time, referring to Figures 3 and 6, a rotating ring 110 is arranged below the limiting ring 107. The rotating ring 110 is coaxially sleeved on the outside of the sealing rod 104. The rotating ring 110 has no contact with the fixed rod 102. A driving ring 111 is rotatably sleeved on the outside of the rotating ring 110. Driving seats 112 are arranged at both ends of the driving ring 111. The upper end of the driving seat 112 is connected to a driving bracket 113. A driving cylinder 114 is arranged on the top of the driving bracket 113. The driving cylinder 114 is located in the plane where the limiting slide groove 108 is located. A limiting rod 115 is slidably arranged in the driving cylinder 114. One end of the limiting rod 115 is connected to the limiting slide seat 109, and the other end is connected to a sealing clamping plate 116.

Specifically, referring to Figure 6, a rotating motor 117 is provided on the rotating ring 110, and the rotating motor 117 is transmission-connected to the driving ring 111. A sealing cylinder 118 is provided on one side of the sealing rod 104, and the output end of the sealing cylinder 118 is vertically upward. The limit ring 107 and the rotating ring 110 are both connected to the output end of the sealing cylinder 118.

The circular ring below the thread of the plastic bottle mouth is a fixed ring. When the two limiting slides 109 move to the lateral ends of the limiting slide groove 108 respectively, the inner end of the limiting rod 115 is in a contracted state, and the distance between the two sealing clamps 116 is greater than the diameter of the fixed ring. In this state, the output end of the sealing cylinder 118 extends out, which can drive the sealing clamp 116 to move above the fixed ring.

When the two limiting slides 109 move to the longitudinal ends of the limiting slide groove 108 respectively, the inner end of the limiting rod 115 is in an extended state, and the distance between the two sealing clamps 116 is larger than the outer diameter of the plastic bottle mouth but smaller than the diameter of the fixing ring. In this state, the output end of the sealing cylinder 118 retracts, which can drive the fixing ring and the plastic bottle to move downward, so that the plastic bottle is in close contact with the sealing ring 106 to achieve sealing.

Through the above arrangement, when the plastic bottle is not inserted into the fixed rod 102, the sealing cylinder 118 is in a retracted state, the limiting ring 107 and the rotating ring 110 are located at the lower part of the sealing rod 104. At this time, the limiting slide 109 is located at the lateral ends of the limiting slide groove 108, the inner end of the limiting rod 115 is in a retracted state, and the distance between the two sealing clamping plates 116 is greater than the diameter of the fixed ring.

When the plastic bottle is inserted into the fixing rod 102 and the bottle mouth is inserted into the upper part of the sealing rod 104, the output end of the sealing cylinder 118 extends out, driving the limiting ring 107 and the rotating ring 110 to move upward, so that the limiting ring 107 moves to the outside of the bottle mouth. Since the distance between the two sealing clamping plates 116 is greater than the diameter of the fixing ring, the sealing clamping plate 116 can move above the fixing ring.

After the sealing clamping plate 116 moves to the top of the fixing ring, the rotating motor 117 is activated to drive the driving ring 111 to rotate 90 degrees, so that the two limiting slides 109 move to the longitudinal ends of the limiting slide groove 108, and the inner end of the limiting rod 115 is in an extended state. The distance between the two sealing clamping plates 116 is greater than the outer diameter of the plastic bottle mouth but smaller than the diameter of the fixing ring;

Then, the output end of the sealing cylinder 118 retracts, driving the limit ring 107 and the rotating ring 110 to move downward. After the sealing clamp 116 moves to contact the upper surface of the fixed ring, as the output end of the sealing cylinder 118 retracts, the sealing clamp 116 drives the fixed ring to move downward, that is, the plastic bottle moves downward, so that the bottle mouth of the plastic bottle is sealed and inserted into the sealing ring 106.

Further, referring to Figure 7, in this embodiment, the packaging belt separation mechanism 2 includes a separation ring 201, which is coaxial with the fixed rod 102. A plurality of clamping cylinders 202 are passed through the separation ring 201. The clamping cylinders 202 are arranged along the radial direction of the separation ring 201. The output end of the clamping cylinder 202 is toward the center of the separation ring 201, and the output end of the clamping cylinder 202 is connected to a suction cup 203.

In the packaging tape separation mechanism 2 of this embodiment, when the output end of the pressing cylinder 202 is extended, the suction cup 203 can be pushed toward the surface of the plastic bottle, thereby adsorbing the packaging tape.

It should be noted that before the suction cup 203 absorbs the packaging belt, the pumping and inflating mechanism 3 is activated first, so that the plastic bottle is inflated, and the body of the plastic bottle expands and becomes smooth, thereby facilitating the suction cup 203 to absorb.

Further, referring to Figure 2, the packaging belt separation mechanism 2 also includes a telescopic cylinder 204, which is vertically arranged above the conical rod 103, and the output end of the telescopic cylinder 204 is vertically downward and connected to a telescopic seat 205, and a rotating motor 206 is arranged on the telescopic seat 205, and the rotating motor 206 is connected to a rotating plate 207, and the rotating plate 207 is horizontally arranged and a plurality of vertical rods 208 are arranged on its lower surface, and the plurality of vertical rods 208 are evenly distributed along the circumference of the rotating plate 207, and a rotating cylinder 209 is rotatably arranged on the outer periphery of the vertical rod 208.

In the above-mentioned packaging belt separation mechanism 2, the output end of the telescopic cylinder 204 extends out, driving the telescopic seat 205, the rotating motor 206, the rotating plate 207, the vertical rod 208 and the rotating cylinder 209 to move downward. Several vertical rods 208 are distributed in a circle, and the circle is coaxial with the fixed rod 102, that is, coaxial with the plastic bottle.

It should be noted that after the suction cup 203 absorbs the packaging tape, the air pumping and inflation mechanism 3 is further actuated to extract the air in the plastic bottle, causing the body of the plastic bottle to shrink and the bottle body to separate from the packaging tape. At this time, the output end of the telescopic cylinder 204 extends to drive the vertical rod 208 and the rotating cylinder 209 to insert into the gap between the bottle body and the packaging tape. Then the rotating motor 206 is actuated to drive the rotating plate 207, the vertical rod 208 and the rotating cylinder 209 to rotate. After the rotating cylinder 209 rotates to the adhesive portion between the packaging tape and the bottle body, the adhesive portion is separated when the rotating cylinder 209 rotates, thereby removing the packaging tape from the bottle body and leaving the packaging tape adhered to the rotating cylinder 209.

Further, referring to Figures 4 and 5, the pumping and inflation mechanism 3 includes a ventilation channel 301 opened in the fixed rod 102, the ventilation channel 301 extends to the tapered rod 103 and the sealing rod 104, the ventilation channel 301 is connected to an air inlet pipe 302 and an air outlet pipe 303, the air inlet pipe 302 is connected to an inflator 304, and the air outlet pipe 303 is connected to an air pump 305.

A three-way valve is connected between the ventilation channel 301, the air inlet pipe 302 and the air outlet pipe 303 to control the connection between the three. When the air inlet pipe 302 is connected to the ventilation channel 301, the end of the tapered rod 103 outputs air, and when the air outlet pipe 303 is connected to the ventilation channel 301, the end of the tapered rod 103 draws air.

It should be noted that this embodiment, by providing a fixing mechanism 1, a packaging band separation mechanism 2 and a pumping and inflation mechanism 3, can more conveniently separate the annular packaging band wrapped and glued to the bottle body of the plastic bottle. The material strength of the packaging bag and the plastic bottle is quite different, so different methods need to be adopted during recycling. After separation, the targeted nature of the recycling process can be improved, thereby improving the recycling effect.

Embodiment 2, referring to Figures 1 to 9, based on the fixing mechanism 1 and the pumping and inflating mechanism 3 set up as above, when the plastic bottle is in an inflated state, a cleaning mechanism 4 is further set. Since the surface of the plastic bottle is relatively smooth when it is in an inflated state, with no wrinkles or few wrinkles, the cleaning effect is better when cleaning in this state.

Specifically, referring to Figures 7, 8 and 9, the cleaning mechanism 4 includes a lifting cylinder 401, which is vertically arranged on one side of the fixed rod 102, and the output end of the lifting cylinder 401 is vertically upward and connected to a horizontal ring 402, the horizontal ring 402 is coaxial with the fixed rod 102, and the inner surface of the horizontal ring 402 is provided with an annular groove 403, a cleaning ring 404 is slidably arranged in the annular groove 403, and a cleaning brush is arranged on the inner surface of the cleaning ring 404, a cleaning motor 405 is arranged on the side of the horizontal ring 402, and an annular rack 406 is arranged on the side of the cleaning ring 404, and the cleaning motor 405 is transmission-connected to the annular rack 406.

Further, referring to Fig. 5, the cleaning mechanism 4 further comprises a cleaning nozzle 407, which is arranged at the top of the tapered rod 103, and a cleaning channel 408 is arranged inside the tapered rod 103, the cleaning channel 408 is connected to the cleaning nozzle 407, and the cleaning channel 408 is connected to a cleaning pipe 409. In the above-mentioned cleaning mechanism 4, the cleaning pipe 409 is connected to a cleaning water tank, which is filled with cleaning liquid, and a water pump is also arranged, and the water outlet of the water pump is connected to the cleaning pipe 409. When the water pump is working, the cleaning liquid can be pumped into the cleaning pipe 409, and the cleaning liquid is sprayed from the cleaning nozzle 407 and sprayed on the inner wall of the plastic bottle.

A reflux channel is also provided inside the fixed rod 102, and the reflux channel extends to the tapered rod 103 and the sealing rod 104. After the cleaning liquid cleans the inner wall of the plastic bottle, it gathers at the bottle mouth under gravity.
