Description

Technical Field

[0001] This utility model relates to the field of plastic bag processing and sealing technology, specifically a continuous sealing machine for plastic bags. Background Technology

[0002] Plastic bags are bags made primarily of plastic (common plastics include polypropylene, polyester, nylon, etc.). They are essential items in people's daily lives and are often used to hold other items. They are widely used because of their low price, light weight, large capacity, and ease of storage. The final processing step for plastic bags is to seal them using a sealing machine.

[0003] The sealing machine consists of a conveying section and a pressing and shearing section. The upper and lower adjacent conveying rollers need to convey the unpressed plastic bags in the pressing direction. In the existing technology, the conveying rollers of the sealing machine are all fixedly installed. Because the distance between the upper and lower conveying rollers is very close, it is very troublesome and inconvenient to feed one end of the plastic bag. Utility Model Content

[0004] The purpose of this invention is to provide a continuous sealing machine for processing plastic bags to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous sealing machine for processing plastic bags, comprising a base, a support frame fixedly connected to the base, a motor fixedly installed on the support frame, symmetrically arranged lifting grooves on the support frame, lifting blocks slidably connected inside each lifting groove, springs fixedly connected to the top of each lifting groove, a first conveying roller rotatably connected between the lifting blocks, a second conveying roller rotatably connected to the support frame at the bottom position corresponding to the first conveying roller, transmission gears fixedly connected to the output shafts of both the first and second conveying rollers, a rotating rod rotatably connected to one side of the support frame via a support plate, a pressing frame fixedly connected to one end of each rotating rod, a pushing frame fixedly connected to the rotating rod, and a pressure rod fixedly connected to each lifting block at the position corresponding to the pressing frame.

[0006] Preferably, the motor output end is fixedly connected to one end of the output shaft of the second conveying roller, and one end of the pressure rod slides through the extrusion frame.

[0007] Preferably, the support frame is C-shaped, with the first conveying roller located at the top of the second conveying roller.

[0008] Preferably, the transmission gears are meshed with each other, and the bottom ends of the springs are all fixedly connected to the lifting block.

[0009] Preferably, a guide rod is fixedly connected to each of the hollow positions of the spring inside the lifting groove, and one end of each guide rod slides through the lifting block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the first conveying roller can be moved upward by the linkage of various components, and the distance between the first conveying roller and the second conveying roller is effectively adjusted. At this time, the operator can place one end of the plastic bag between the first conveying roller and the second conveying roller to complete the feeding of the plastic bag. The operation is more convenient and practical, and it is worth promoting and using. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides a technical solution: a continuous sealing machine for processing plastic bags, including a base 1, a support frame 2 fixedly connected to the base 1, a motor 3 fixedly installed on the support frame 2, symmetrically arranged lifting grooves 4 on the support frame 2, lifting blocks 5 slidably connected inside the lifting grooves 4, springs 6 fixedly connected to the top of the lifting grooves 4, a first conveying roller 7 rotatably connected between the lifting blocks 5, a second conveying roller 8 rotatably connected to the support frame 2 at the bottom position corresponding to the first conveying roller 7, transmission gears 9 fixedly connected to the output shafts of the first conveying roller 7 and the second conveying roller 8, a rotating rod 10 rotatably connected to one side of the support frame 2 through a support plate, a pressing frame 11 fixedly connected to one end of the rotating rod 10, a pushing frame 12 fixedly connected to the rotating rod 10, and a pressure rod 13 fixedly connected to the lifting blocks 5 at the position corresponding to the pressing frame 11.

[0017] The output end of motor 3 is fixedly connected to one end of the output shaft of the second conveying roller 8. One end of the pressure rod 13 slides through the extrusion frame 11. Motor 3 can easily drive the second conveying roller 8 to rotate. When the extrusion frame 11 rotates, it can easily drive the pressure rod 13 to move. The support frame 2 is C-shaped. The first conveying roller 7 is located at the top of the second conveying roller 8. The transmission gears 9 are meshed with each other. The bottom end of spring 6 is fixedly connected to the lifting block 5. The meshing of transmission gears 9 can easily make the first conveying roller 7 and the second conveying roller 8 rotate at the same time. Inside the lifting groove 4, a guide rod 14 is fixedly connected to the hollow position of spring 6. One end of the guide rod 14 slides through the lifting block 5. The guide rod 14 can easily guide the movement of the lifting block 5.

[0018] Specifically, when using this utility model, the push frame 12 can be rotated away from the support frame 2. The rotating push frame 12 will drive the two rotating rods 10 to rotate together. The rotation of the rotating rods 10 will drive the extrusion frame 11 to rotate upward. The upward rotating extrusion frame 11 will extrude pressure on the pressure rod 13. The pressure rod 13 will also drive the lifting block 5 to slide upward inside the lifting groove 4. The upward movement of the lifting block 5 is guided by the guide rod 14. At the same time, the moving lifting block 5 will also compress and contract the spring 6. The moving lifting block 5 will also drive the first conveying roller 7 to move upward. At this time, the top transmission gear 9 and the bottom transmission gear 9 separate, and the distance between the first conveying roller 7 and the second conveying roller 8 increases. One end of the plastic bag can be placed between the first conveying roller 7 and the second conveying roller 8. Then, the push frame 12 is released, and the spring 6 will drive the lifting block 5 to return to its original position. The lifting block 5 will also drive the first conveying roller 7 to return to its original position. At this time, the first conveying roller 7 and the second conveying roller 8 clamp one end of the plastic bag. The two transmission gears 9 are reconnected, and the motor 3 can be started. The motor 3 will drive the second conveying roller 8 and the transmission gear 9 to rotate. The bottom transmission gear 9 will drive the top transmission gear 9 to rotate. At this time, the top transmission gear 9 will drive the first conveying roller 7 to rotate. The first conveying roller 7 and the second conveying roller 8 will rotate in the same direction to transport the clamped plastic bag, so that the entire sealing device can perform continuous sealing work normally.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
