Description

Technical Field

[0001] This utility model relates to the field of paper material processing technology, specifically to a pressing device for paper packaging materials. Background Technology

[0002] To facilitate the preservation of goods, packaging bags are currently the most common way to achieve this purpose. The processing of existing packaging materials is generally done by pressing them with some equipment. Paper packaging materials are the most commonly used packaging materials because they are lightweight, low in cost, and have a strong load-bearing capacity.

[0003] However, existing paper packaging material pressing devices still have many shortcomings in actual use. For example, existing pressing devices use pressure plates to press paper packaging materials, but during the pressing process, the pressure plates often shift, resulting in inaccurate pressing positions, which makes it impossible to press the paper packaging materials, or excessive pressure may cause damage to the paper packaging materials. Utility Model Content

A push rod is connected to the bottom of the cylinder. A connecting plate is installed at one end of the push rod. The push rod is fixedly connected to the middle of the top of the connecting plate. Multiple springs are equidistantly installed at the bottom of the connecting plate. A pressure plate is connected to the connecting plate through the springs. Telescopic rods are symmetrically installed on both sides of the top of the pressure plate between two springs. The top of the telescopic rods is fixedly connected to the connecting plate.

[0008] Preferably, the outer surface of the roller is covered with dust-adhesive rubber, and the bottom of the pressure plate is set as a smooth curved surface.

[0009] Preferably, there is a gap between the pressure plate and the support plate, and both ends of the spring are fixedly connected to the connecting plate.

[0010] A glue spraying assembly is installed at the middle position of the top of the two bases. The glue spraying assembly includes a glue box, a glue inlet pipe, a connecting pipe, a glue spraying head, and a scraper.

[0016] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use;

[0017] 1. Equipped with a compression component, when the paper packaging material on the support plate and partition plate is sprayed with glue and guided to be pressed together, the paper packaging material passes under the pressure plate. The cylinder moves downward to compress the packaging material, and the spring is compressed, so that the pressure plate applies force evenly to the paper packaging material during pressing, avoiding excessive pressure that may damage the paper packaging material. The telescopic rod fixes the positional relationship between the pressure plate and the connecting plate, preventing the spring from deflecting during pressing and causing the pressure plate to shift its pressing position. The bottom of the pressure plate is set with a smooth curved surface to prevent the pressure plate from damaging the paper packaging material.

[0018] 2. Equipped with a glue spraying component, when the paper packaging material on the support plate passes the glue spraying head, the glue spraying nozzle at the bottom of the spraying head sprays glue. The glue flows downward on the scraper, and the lower end of the scraper causes the glue to rub against the paper packaging material, ensuring that both sides of the paper packaging material are covered with glue. This determines the position of the glue on the paper packaging material. Because the roller is covered with a dust-adhesive rubber, when the paper material comes into contact with the roller, the roller will absorb the debris and dust on the surface of the paper material, making the paper material cleaner and tidier, allowing the next step of the process to proceed.

[0019] 3. Equipped with a guide assembly, when the paper packaging material on the partition passes the guide wheel, the guide wheel moves the paper packaging material towards the support plate, where it adheres to the paper packaging material on the support plate. When the guide wheel compresses the two paper packaging materials, pressure is generated between the guide wheel and the paper packaging materials. The return spring compresses and adjusts the distance between the guide wheel and the paper packaging materials, so that the guide wheel applies force evenly to the paper packaging materials, making the glue between the two paper packaging materials adhere more tightly and preventing excessive force during the glue adhesion process from causing overflow.

[0040] The working principle and usage process of this utility model: One paper packaging material enters the device from above the partition 2, and another paper packaging material enters the device from the support plate 3. The paper material on the partition 2 moves on the roller 7. The outer side of the roller 7 is fitted with a dust-adhesive rubber, which will absorb the debris and dust on the surface of the paper packaging material. When the paper packaging material on the support plate 3 passes through the glue spraying head 504, glue will be sprayed out from the bottom nozzle of the glue spraying head 504. The glue flows on the scraper 505. The lower end of the scraper 505 scrapes the two ends of the paper packaging material, so that the glue adheres to the two ends of the paper packaging material.

[0041] When the paper packaging material on the support plate 3 has glue adsorbed on both ends, the paper packaging material on the partition plate 2 moves to the guide wheel 602 through the action of the roller 7. The guide wheel 602 changes the forward path of the paper packaging material on the partition plate 2, causing the paper packaging material on the partition plate 2 to move downward and overlap with the paper packaging material on the support plate 3. The guide wheel 602 presses the two paper materials together, and pressure is generated between the guide wheel 602 and the paper packaging material. The return spring 604 will compress and adjust the distance between the guide wheel 602 and the paper packaging material, so that the guide wheel 602 applies force evenly to the paper packaging material, making the glue between the two paper packaging materials stick more tightly, and making the two ends of the two paper packaging materials stick together.

[0042] After the edges of the two paper packaging materials are glued together, the paper packaging materials move to the bottom of the pressure plate 807. One end of the cylinder 802 is connected to the push rod 803, and the other end of the push rod 803 is connected to the connecting plate 804. The connecting plate 804 and the pressure plate 807 are connected by the spring 806 and the telescopic rod 805. The cylinder 802 extends and retracts, causing the pressure plate 807 to press down, so that the two paper packaging materials are completely overlapped, thus completing the pressing function.

[0043] After pressing, one end of the paper packaging material is connected to the collecting roller 13. When the motor 10 starts, the motor drives the roller 12 to rotate. The collecting roller 13 is connected to the roller 12. The collecting roller 13 rotates, so that the processed paper packaging material is collected on the collecting roller 13, which is convenient for the next step of processing and production.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
