Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag processing, in particular to an edge sealing machine for plastic bag processing. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their advantages of being cheap, extremely light, large in capacity, and easy to store. However, due to the disadvantages of their extremely long degradation cycle and difficulty in handling, their production and use are banned in some countries. When producing plastic bags, an edge sealing machine is required to seal two pieces of plastic film together into a plastic bag.

[0003] In the process of plastic bag processing, an edge banding machine is needed. The Chinese utility model patent with the announcement number CN215243257U discloses an edge banding machine for plastic bag processing, which relates to the field of edge banding machines, including an edge banding machine body, a mounting plate fixedly installed on the edge banding machine body, a support rod slidably installed on the mounting plate, a motor fixedly installed on the support rod, a motor shaft fixedly installed on the output end of the motor through a coupling, a rotating shaft fixedly installed on the motor shaft, a rotating shaft fixedly installed on the rotating shaft, a plurality of fan blades fixedly installed on the rotating shaft, a shield fixedly installed on the motor, the shield sleeved on the fan blade, a support plate fixedly installed on the mounting plate, and the other end of the support plate fixedly installed on the edge banding machine body. The utility model, through the setting of the fan blades, when the edge banding machine is used to produce plastic bags, the plastic bags are cooled in time by the rotating fan blades, so that the adhesion part of the plastic bag is stable and will not be separated again when subjected to force, thereby ensuring the edge banding effect of the edge banding machine and improving the practicality of the edge banding machine.

[0004] However, during the use of the utility model, since the texture of the plastic bag is relatively soft, when the staff seals the edge of the plastic bag, the staff is required to hold the plastic bag throughout the process to complete the edge sealing process. This method has low working efficiency and can only process a single plastic bag at a time, which cannot meet production needs. Therefore, a plastic bag processing edge sealing machine is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an edge banding machine for plastic bag processing, which has the advantage of improving the efficiency of edge banding of plastic bags and solves the problem that due to the soft texture of plastic bags, when workers are sealing the edges of plastic bags, they need to drag the plastic bags the whole time to complete the edge banding process. This method has low working efficiency and can only process a single plastic bag at a time, which cannot meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an edge banding machine for processing plastic bags, comprising a workbench and a conveyor belt device fixedly installed on the top of the workbench, wherein an edge banding mechanism for banding the plastic belt is arranged on the top of the conveyor belt device;

[0007] The edge sealing mechanism includes a support frame fixedly connected to the top of the workbench, the conveyor belt device is located inside the support frame, an electric push rod extending into the interior is fixedly installed on the top of the support frame, a connecting plate is fixedly connected to the output end of the electric push rod, and a heat sealing plate is fixedly installed on the side of the connecting plate close to the conveyor belt device.

[0008] Furthermore, a driving device for driving the conveyor belt device is arranged inside the workbench, and a heating mechanism for heating the heat sealing plate is arranged inside the workbench.

[0009] Furthermore, the front and back sides of the top of the workbench are fixedly connected with support plates, and the tops of the two support plates are fixedly connected with a top plate.

[0010] Furthermore, a cutting knife is provided on one side of the top plate close to the conveyor belt device, a return spring is fixedly connected to the cutting knife and the side opposite to the top plate, a driving motor is fixedly installed on the top of the top plate, and an eccentric wheel extending to the bottom of the top plate is fixedly connected to the output shaft of the driving motor.

[0011] Furthermore, the lower surface of the eccentric wheel is in contact with the upper surface of the cutting knife, and a movable groove adapted to the eccentric wheel is provided inside the top plate.

[0012] Furthermore, the front and back sides of the top of the workbench are fixedly connected with mounting plates, the tops of the two mounting plates are fixedly connected with fixing plates, the tops of the fixing plates are threadedly connected with threaded rods extending to their bottoms, and one end of the threaded rods close to the conveyor belt device is rotatably connected with a limiting plate.

[0013] Furthermore, one end of the threaded rod away from the limiting plate is fixedly connected to a rotating handle, and one side of the limiting plate close to the threaded rod is fixedly connected to a positioning guide rod extending to the top of the fixing plate.

[0014] Furthermore, a support base is fixedly connected to the bottom of the workbench, and the number of the support bases is four, and the four support bases are evenly distributed on the bottom of the workbench.

[0015] Compared with the prior art, the utility model provides an edge banding machine for plastic bag processing, which has the following beneficial effects:

[0016] 1. The edge sealing machine for plastic bag processing drives the connecting plate to move downward by arranging an electric push rod, and then drives the heat sealing plate to move downward by the connecting plate, so as to perform edge sealing on the plastic bag. Then, by arranging a conveyor belt device, the plastic bag can be conveyed, so as to facilitate continuous edge sealing of the plastic bag, thereby improving the work efficiency of plastic bag processing. At the same time, since the heat sealing plate is U-shaped, the three sides of the plastic bag can be heat-sealed at one time, thereby improving the work efficiency.

[0017] 2. The edge banding machine for plastic bag processing drives the eccentric wheel to rotate by setting a driving motor, and then sets a reset spring to enable the cutting knife to undergo elastic displacement. At this time, the eccentric wheel squeezes the cutting knife, thereby facilitating the cutting of the edge-banded plastic bag. This solves the problem that due to the soft texture of the plastic bag, when the staff performs edge banding on the plastic bag, they need to hold the plastic bag throughout the process to complete the edge banding. This method has low working efficiency, can only process a single plastic bag at a time, and cannot meet the production needs. BRIEF DESCRIPTION OF THE DRAWINGS
