Description

Packaging equipment and preparation process of layered double metal hydroxide adsorbent

Technical Field

The invention belongs to the field of transportation technology, in particular to the technical field of packaging fluid solid materials, and in particular to a packaging device and a preparation process of a layered double metal hydroxide adsorbent.

Background Art

The layered double hydroxide adsorbent is in powder form and needs to be filled during the production process. During the filling process, the packaging film is heat-sealed with a heat-sealing strip to form a packaging bag. However, the powdered layered double hydroxide adsorbent is easily melted by heat when the packaging film is heat-sealed. Some of the melted powder sticks to the inner wall of the packaging bag, affecting the quality of the layered double hydroxide adsorbent, and some of it is directly mixed in the heat-sealed position of the packaging bag, resulting in a decrease in the heat-sealing effect. When the layered double hydroxide adsorbent is filled into the packaging bag where the heat-sealing effect is affected, the heat-sealed position may even be broken due to the impact of the filling.

Therefore, due to the technical problem that powdered substances are easily affected by the heat of heat sealing during the filling process and melted, resulting in a decrease in the heat sealing effect, it is necessary to design a new packaging equipment and a preparation process for layered double metal hydroxide adsorbents.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in FIGS. 1 to 8 , in at least one embodiment, a packaging device is provided, comprising: a filling device 1 and a heat sealing device 2; the filling device 1 is arranged above the heat sealing device 2; the heat sealing device 2 is suitable for receiving the material filled by the filling device 1 after heat sealing the packaging film; wherein the heat sealing device 2 comprises: a pair of first heat sealing strips 21, and a carrier plate 22 corresponding to the first heat sealing strips 21; the first heat sealing strips 21 are arranged horizontally; the carrier plate 22 is arranged above the corresponding first heat sealing strips 21; when the two first heat sealing strips 21 are close to each other, the carrier plate 22 rotates downward; when the two first heat sealing strips 21 are separated from each other, the carrier plate 22 gradually rotates to a horizontal position, and at this time, there is a gap between the two carrier plates 22; after the heat sealing is completed, the two first heat sealing strips 21 are separated from each other, so as to avoid the material being melted by the heat of the heat sealing during filling, thereby ensuring the effect of the heat sealing, and after the bottom of the packaging bag is heat-sealed, the impact force of the filled material is carried by the carrier plate 22, so as to avoid the material directly impacting the heat sealing position, thereby ensuring that the packaging bag is not damaged by the impact, and ensuring the filling of the material.

After the first heat sealing strip 21 heat-seals the bottom of the packaging bag, the two first heat sealing strips 21 will move away, that is, the distance between the first heat sealing strips 21 will increase. At this time, the supporting plate 22 is located in the space above the first heat sealing strip 21, and the two supporting plates 22 are horizontal. The heat sealing position at the bottom of the packaging bag is located below the supporting plate 22. A gap is left between the two supporting plates 22, and the gap can facilitate the packaging film forming the packaging bag to continue to be transported downward. The filling device 1 fills the powdered material, such as powdered layered double metal hydroxide adsorbent. Most of the powdered material will be blocked by the supporting plate 22 to prevent the material from directly impacting the heat sealing position and preventing the packaging bag from being impacted and ruptured. At this time, the first heat sealing strip 21 is already away from the heat sealing position to prevent the temperature of the first heat sealing strip 21 from affecting the material.

As shown in Figures 2 and 3, an inclined groove 221 is provided on the side wall of the carrying plate 22, and the end of the inclined groove 221 close to the other carrying plate 22 is at a lower position; the part of the top surface of the carrying plate 22 close to the other carrying plate 22 is an inclined surface, and when the carrying plate 22 rotates, the inclined surface can increase the gap width between the two carrying plates 22, which is convenient for transporting the packaging bag downward; through the cooperation of the inclined groove 221 and the protrusion 243, the corresponding carrying plate 22 can be driven to tilt downward during the process of the first mounting plate 24 and the second mounting plate 241 approaching, that is, the two carrying plates 22 gradually form a V-shaped shape, and in the process of the first mounting plate 24 and the second mounting plate 241 gradually approaching, the two first heat sealing strips 21 gradually approach each other, and the carrying plate 22 gradually rotates downward, at this time, the conveying roller 17 will continue to convey downward The packaging film is fed, and at this time the packaging bag filled with materials moves downward, and the two supporting plates 22 rotate downward to enlarge the gap between the two supporting plates 22, which is convenient for transporting the packaging bag downward. During the transportation of the packaging bag downward, the supporting plates 22 will contact the packaging bag, so that part of the air in the packaging bag will be squeezed out. When the top of the packaging bag filled with materials moves downward to between the two first heat-sealing strips 21, the two first heat-sealing strips 21 just heat-seal the top of the packaging bag to form a sealed packaging bag to prevent the materials in the packaging bag from falling out. The materials in the packaging bag are at a certain distance from the top of the packaging bag to prevent the materials from melting when the top of the packaging bag is heat-sealed. Since part of the air inside the packaging bag is squeezed out before the top of the packaging bag is heat-sealed, the volume of the packaging bag will be reduced, which is more convenient for subsequent transportation and stacking and storage of the packaging bag.

A rotation hole 222 is formed on the side wall of the supporting plate 22 . The rotation hole 222 is disposed close to another supporting plate 22 . The second limiting shaft 31 passes through the rotation hole 222 to facilitate the rotation of the supporting plate 22 .

When the top of the packaging bag filled with materials moves downward to the first heat-sealing strip 21, the two first heat-sealing strips 21 heat-seal the top of the packaging bag to form a sealed packaging bag to prevent the materials in the packaging bag from falling out. The materials in the packaging bag are at a certain distance from the top of the packaging bag to prevent the materials from melting when the top of the packaging bag is heat-sealed. Since part of the air inside the packaging bag is squeezed out before the top of the packaging bag is heat-sealed, the volume of the packaging bag will be reduced, which is more convenient for subsequent transportation and stacking and storage of the packaging bag.
