Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a curing device for plastic packaging bags. Background Art

[0002] A plastic packaging bag is a packaging bag made of plastic as raw material and is used for various articles in production and life, and is widely used in daily life and industrial production.

[0003] The curing of packaging bags is one of the important steps in the production process. Curing is a process in which the adhesives in the packaging bags fully react and solidify through certain time and temperature settings to achieve the best compliance strength and remove residual solvents. The commonly used method at present is to wind the produced plastic film into a roll and place it in a constant-temperature room in a suspended manner. After adjusting the temperature to the required curing temperature, the plastic film is placed for a certain period of time. The length of the placement time varies according to the thickness of the plastic bag and the type of adhesive used. This is the common curing chamber in the plastic bag production process. Generally, such a curing chamber is provided with a relatively wide sealing door to facilitate the handling of the rolled plastic bags.

[0004] However, such a method has certain drawbacks. Each time when transporting the rolled plastic bag film, the sealing door will be opened, which will break the constant-temperature environment in the curing chamber. Although the transportation time is short, the temperature difference between the inside and outside of the curing chamber will also cause the rapid loss of internal heat, resulting in the change of the temperature of some plastic films that have not reached the required time, which will affect the curing efficiency to a certain extent. At the same time, after closing the sealing door, the curing chamber also needs to be temperature-controlled through temperature control equipment, thus increasing the energy consumption.

[0005] Therefore, it is necessary to provide a new curing device for plastic packaging bags to solve the above technical problems. Summary of the Utility Model

[0008] Preferably, a connection box is fixedly installed on any one of the fixed pipes. Two baffle plates are slidably installed in the connection box. Semi-circular grooves are formed on one side of the two baffle plates close to each other. One end of the transverse rod penetrates through the two semi-circular grooves. A bidirectional lead screw is fixedly installed in the connection box. Transmission plates are fixedly installed on the outer walls of one side of the two baffle plates.

[0029] The working principle of the plastic packaging bag aging equipment provided by the present utility model is as follows:

[0030] When it is necessary to age the plastic bag film during the processing process, first, the staff can open the sealing door 401. After the sealing door 401 is opened, the corresponding first runner can be rotated. After the first runner rotates, it drives the adjusting rod one 10 to rotate. Then, through the transmission of the first bevel gear set 11, the bidirectional lead screw 8 is driven to rotate, so that the two transmission plates 9 move away from each other, and further the two shielding plates 7 move away from each other. In this way, the two shielding plates 7 no longer enclose the fixed tube 4. After adjusting to a suitable size (the distance between the two shielding plates 7 is slightly larger than the diameter of the roll-shaped plastic bag film to be placed), then the pin rod 1301 is pulled out.

[0031] At this time, the staff can put one end of the rolled plastic bag film into the fixed tube 4, slightly lift the plastic bag film to make its center correspond to the cross bar 6 and push it into the outer box body 1. At this time, the plastic bag film is sleeved on the cross bar 6 and completely enters the outer box body 1 under the influence of external force. During this process, the staff needs to continuously apply pressure to the plastic bag film to make one end of it contact the contact plate 12 and drive the contact plate 12 to move horizontally, so that the compression spring 1201 is gradually compressed. Then, insert the pin rod 1301 into the embedding hole 13 again. After releasing the plastic bag film, under the reset effect of the compression spring 1201, the plastic bag film will slide back a short distance and stop after contacting the pin rod 1301. In this way, the plastic bag film can be limited in position and cannot shake.

[0032] Then, the second runner can be rotated. The rotation of the second runner will drive the second adjusting rod 16 to rotate, and then drive the threaded rod 15 to rotate through the transmission of the second bevel gear set 17, so as to drive the lifting plate 18 to move upward. Finally, the top arc surface of the support plate 20 contacts the cross bar 6 to support one end of the cross bar 6 and ensure the stability of the suspended plastic bag film.

[0033] Furthermore, the first runner can be rotated in the reverse direction. Through the above reverse transmission, the two baffle plates 7 approach each other for preliminary sealing. Then, the sealing door 401 can be used for sealing. When taking out the plastic bag film, open the two baffle plates 7 through the above operation, rotate the second runner again to make the support plate 20 move slightly downward for a certain distance. After pulling out the pin rod 1301, the plastic bag film will still slide back under the reset effect of the compression spring 1201. At this time, rotate the second runner again to make the multiple load-bearing cylinders 21 on the top of the support plate 20 contact the outer wall of the plastic bag film. At this time, the plastic bag film can be pulled out horizontally.
