[0023] As illustrated in Figures 1-3, this utility model provides a technical solution:

[0024] A sealing device for plastic film bags includes a sealing machine body 1. A first base plate 2 is provided at the bottom of the sealing machine body 1. A second base plate 3 is provided on the front side of the first base plate 2. A frame 4 is provided on the upper side of the second base plate 3. A conveyor belt 5 is installed on the inner side of the frame 4. Connecting seats 6 are provided on the front of the left and right sides of the first base plate 2. A slot 7 is provided on the front of the connecting seat 6. A limiting screw 8 is provided on the outer side of the connecting seat 6. A knob 9 is provided on the outer end of the limiting screw 8. Outer protrusions 10 are provided on the rear of the left and right sides of the second base plate 3. An insert plate 11 is provided on the rear side of the outer protrusions 10. A threaded hole 12 is provided on the side wall of the insert plate 11.

[0025] In this embodiment, the sealing machine body 1 is a plastic film bag sealing machine, which mainly uses heat pressing to seal plastic film bags. The conveyor belt 5 is connected to the frame 4 by a rotating connection, and a motor is installed on the outside of the frame 4 corresponding to the conveyor belt 5. The limiting screw 8 passes through the connecting seat 6 and extends into the slot 7, and the limiting screw 8 is connected to the connecting seat 6 by a threaded connection. The size of the insert plate 11 is adapted to the size of the slot 7, and the insert plate 11 is connected to the slot 7 by a sliding connection. The limiting screw 8 is positioned corresponding to the threaded hole 12, and the limiting screw 8 is connected to the threaded hole 12 by a threaded connection. The connecting seat 6, slot 7, outer protrusion plate 10, and insert plate 11 can be inserted and removed to facilitate the splicing of the first base plate 2 and the second base plate 3. The limiting screw 8, knob 9, and threaded hole 12 can limit the insert plate 11 in the slot 7. In summary, the design facilitates the installation and disassembly of the sealing machine body 1 and the conveyor belt 2.

[0026] The working process of this utility model is as follows: When assembling the sealing machine body 1 and the conveyor belt 5, the first base plate 2 and the second base plate 3 are first spliced ​​together. Since the size of the insert plate 11 matches the size of the slot 7, and the connection between the insert plate 11 and the slot 7 is a sliding connection, the insert plate 11 will be inserted into the slot 7. Then, the limiting screw 8 is rotated by the knob 9. Since the limiting screw 8 passes through the connecting seat 6 and extends into the slot 7, and the connection between the limiting screw 8 and the connecting seat 6 is a threaded connection, the position of the limiting screw 8 corresponds to the threaded hole 12, and the connection between the limiting screw 8 and the threaded hole 12 is a threaded connection. Then, the limiting screw 8 will be screwed into the threaded hole 12, thus completing the sealing process. When the sealing machine body 1 and the conveyor belt 5 are connected and disassembled, the limiting screw 8 is rotated in the opposite direction by the knob 9. Then the limiting screw 8 will turn out of the threaded hole 12. At this time, the insert plate 11 will lose its limit. Then the second base plate 3 is pulled forward, and the insert plate 11 will be pulled out from the slot 7. At this time, the disassembly of the sealing machine body 1 and the conveyor belt 5 is completed. The connection seat 6, slot 7, external protrusion plate 10 and insert plate 11 can be inserted and removed to facilitate the connection between the first base plate 2 and the second base plate 3. The limiting screw 8, knob 9 and threaded hole 12 can limit the insert plate 11 in the slot 7. In summary, the design facilitates the installation and disassembly of the sealing machine body 1 and the conveyor belt 2.

[0027] 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.
