Description

Adhesive tape coating roller

Technical Field

The utility model relates to the field of adhesive tape coating, in particular to an adhesive tape coating roller.

Background Art

During the production process of the tape, a glue with a specific function needs to be coated on its surface, and then it is dried and rolled up. During the gluing process, a coating roller is required to complete the gluing and gluing. The traditional gluing mechanism is to have multiple sets of mutually bonded outer edge surfaces of the gluing rollers bonded to each other, so that the lowermost gluing roller is immersed in the glue liquid, and the glue liquid is brought out during the rotation of the gluing roller. This gluing method cannot control the amount of glue applied, and is difficult to be applied to the production of tapes of different specifications. Moreover, after the coating roller is used for a long time, the glue liquid is easy to remain on the coating roller, resulting in the outer edge surface of the coating roller being unable to completely bond with the tape, resulting in uneven coating. Workers need to regularly clean or replace the coating roller, which greatly increases the production cost.

For example, in the prior art, a high-speed tape coating machine disclosed in announcement number CN209985680U has distribution holes on the coating roller shaft so that the glue on the inner side of the shaft can be discharged to the coating body to complete the gluing. Although the amount of glue applied can be effectively controlled, the distribution holes and the coating body will still be blocked by the glue. Once the glue solidifies during shutdown, the coating roller needs to be replaced, which has low practicality.

Utility Model Content

In view of the above situation, in order to overcome the defects of the prior art, the utility model adopts a tape coating roller, which solves the problems of uneven gluing and the coating roller being easily blocked by glue in the prior art.

The technical solution is to provide a tape coating roller, comprising a supporting roller, wherein the axis of the supporting roller is horizontally placed front and back, and grooves penetrating the front and rear end surfaces and the outer edge surface are respectively provided at the upper and lower ends of the supporting roller, and a rotating roller is rotatably connected to the outer edge surface of the supporting roller, and the rotating roller is a tubular shell coaxially placed with the supporting roller, the inner edge surface of the rotating roller is in contact with the outer edge surface of the supporting roller and the rotating roller can rotate around the axis, and a plurality of through holes penetrating the inner and outer end surfaces are evenly provided on the outer edge surface of the rotating roller, and circular baffles are respectively fixed at the front and rear ends of the supporting roller, and the two circular baffles are respectively in contact with the front and rear end surfaces of the rotating roller and can seal the groove, and an upper and lower transverse tubes are fixed on the front circular baffle, the upper transverse tube is connected with the upper groove and can extract the gas in the upper groove, and the lower transverse tube is connected with the lower groove and can inflate the lower groove; a feeding pipe with a vertical axis is provided at the upper end of the rotating roller, and the lower end surface of the feeding pipe is in contact with the outer edge surface of the rotating roller.

A support shaft is coaxially fixed to the front and rear ends of the support roller, and the support shaft passes through the circular baffles on the front and rear sides.

The front end face of the support roller is arranged at intervals with the circular baffle on the front side, and a circular ring is mounted on each support shaft at the interval between the support roller and the circular baffle. Three straight rods are evenly distributed along the circumference at the outer ends of the circular rings, and the outer end of each straight rod is fixed to the inner edge surface of the rotating roller. A fan-shaped filter is fixed to the fan-shaped area between every two straight rods, and the fan-shaped filter is placed between the trough and the horizontal tube.

The lower end surface of the feeding tube is fixed with an arc plate, the lower end surface of the arc plate is in contact with the outer edge surface of the rotating roller, and a plurality of feeding holes penetrating the upper and lower end surfaces are provided on the inner side of the feeding tube.

A fan is arranged at the front end of the circular baffle plate on the front side, the air intake of the fan is connected with the upper side transverse pipe, and the air outlet of the fan is connected with the lower side transverse pipe.

The rotating roller has a certain thickness so that the through hole can accommodate a sufficient amount of glue.

The front and rear end surfaces of the straight rod are respectively fitted with the circular baffle and the supporting roller.

Compared with the prior art, the utility model has the following advantages:

1. The fan drives the airflow to continuously evacuate the upper trough and inflate the lower trough, so that the glue in the feeding pipe can enter the through hole at a uniform speed and be discharged evenly after rotating to the lower position with the rotating roller, so as to achieve quantitative gluing while avoiding the glue residue in the through hole, which will cause the glue to solidify and block the through hole after shutdown;

2. The glue liquid that may enter the upper trough is blocked by the fan-shaped filter. When the fan-shaped filter rotates to the lower horizontal pipe position, the glue liquid blocked inside the filter can be backwashed into the lower trough, preventing the glue liquid from entering the fan and clogging the filter.

DETAILED DESCRIPTION

The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 4, the utility model includes a support roller 1, the axis of the support roller 1 is horizontally placed front and back, and the upper and lower ends of the support roller 1 are respectively provided with a sink groove 2 that penetrates the front and rear end surfaces and the outer edge surface, and the outer edge surface of the support roller 1 is rotatably connected with a rotating roller 3, and the rotating roller 3 is a tubular shell coaxially placed with the support roller 1. The inner edge surface of the rotating roller 3 is in contact with the outer edge surface of the support roller 1 and the rotating roller 3 can rotate around the axis. The outer edge surface of the rotating roller 3 is evenly provided with a plurality of through holes 4 that penetrate the inner and outer end surfaces. Circular baffles 5 are fixed at the front and rear ends respectively, and the two circular baffles 5 are respectively in contact with the front and rear end surfaces of the rotating roller 3 and can seal the groove 2. An upper and lower transverse tubes 6 are fixed on the front circular baffle 5. The upper transverse tube 6 is connected with the upper trough 2 and can extract the gas in the upper trough 2, and the lower transverse tube 6 is connected with the lower trough 2 and can inflate the lower trough 2. A discharge pipe 7 with a vertical axis is provided at the upper end of the rotating roller 3, and the lower end surface of the discharge pipe 7 is in contact with the outer edge surface of the rotating roller 3.

A support shaft 8 is coaxially fixed to the front and rear ends of the support roller 1, and the support shaft 8 passes through the circular baffles 5 on the front and rear sides.

The front end face of the support roller 1 is arranged at an interval with the circular baffle 5 on the front side. A circular ring 9 is mounted on each support shaft 8 at the interval between the support roller 1 and the circular baffle 5. Three straight rods 10 are evenly distributed along the circumference at the outer end of the circular ring 9. The outer end of each straight rod 10 is fixed to the inner edge surface of the rotating roller 3. A fan-shaped filter screen 11 is fixed to the fan-shaped area between every two straight rods 10. The fan-shaped filter screen 11 is placed between the trough 2 and the horizontal tube 6.

In order to prevent the glue in the discharge pipe 7 from being quickly discharged downward into the through hole 4 on the upper side, an arc plate 12 is fixed to the lower end face of the discharge pipe 7, and the lower end face of the arc plate 12 is in contact with the outer edge face of the rotating roller 3. A plurality of discharge holes 13 penetrating the upper and lower end faces are provided on the inner side of the discharge pipe 7.

A fan is arranged at the front end of the circular baffle 5 , the air intake of the fan is connected to the upper horizontal pipe 6 , and the air outlet of the fan is connected to the lower horizontal pipe 6 .

The rotating roller 3 has a certain thickness so that the through hole 4 can accommodate a sufficient amount of glue.

The front and rear end surfaces of the straight rod 10 are respectively in contact with the circular baffle 5 and the supporting roller 1 .

When the utility model is in use, the overall position of the device is first fixed by the support shaft 8, so that the adhesive tape to be coated passes through the lower side of the rotating roller 3 and the height of the adhesive tape is adjusted so that the adhesive tape fits the lower end surface of the rotating roller 3, so that the movement of the adhesive tape can drive the rotating roller 3 to rotate synchronously, and then the glue liquid is injected into the lower material pipe 7. Since the glue liquid has a certain viscosity and the aperture of the discharge hole 13 is small, after the glue liquid moves downward to the position of the arc plate 12, it is blocked by the arc plate 12 and cannot continue to move downward. At this time, the fan is started, and the upper side horizontal pipe 6 The gas in the upper trough 2 can be extracted to form a negative pressure, so that the glue in the feeding pipe 7 enters the upper through hole 4 through the feeding hole 13. Since the rotating roller 3 is constantly rotating, the downwardly moving glue can be continuously filled in the through hole 4. When the through hole 4 rotates to the corresponding position of the lower trough 2, all the glue in the through hole 4 can be discharged downward to the upper end surface of the tape under the inflation effect of the lower horizontal tube 6 to achieve gluing. Since the fan speed is constant, the rotating roller 3 speed is constant, and the glue amount is also constant, achieving quantitative gluing;

In order to prevent the fan from sucking the glue liquid into the upper horizontal tube 6, a fan-shaped filter screen 11 is provided to block the glue liquid. Since the filter screen 11 always rotates with the rotating roller 3, the glue liquid blocked on the inner side of the filter screen 11 can be recoiled to the lower side trough 2 by the airflow when it rotates to the position of the lower horizontal tube 6 with the rotating roller 3, thereby preventing the fan-shaped filter screen 11 from being blocked. In order to prevent the airflow from passing through the upper and lower side troughs 2 and moving directly upward along the filter screen, three straight rods 10 evenly distributed along the circumference are provided to block the filter screen 11, thereby preventing the airflow in the upper and lower groups of horizontal tubes 6 from completing convection directly on the inner side of the fan-shaped filter screen 11, thereby reducing the efficiency of the fan.
