DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a sealing device for biodegradable packaging materials, including a bottom plate 1 and an adjusting mechanism, a pressure seat 14 is fixedly connected to the upper surface of the bottom plate 1, a lifting box 12 that can be lifted and moved is arranged above the bottom plate 1 through a driving mechanism, and a heat sealing block 13 is fixedly connected to the bottom of the lifting box 12 in a transverse direction.

[0020] The inner cavity of the lifting box 12 is laterally provided with a rotatable bidirectional threaded rod 16 through a transmission mechanism, and both ends of the surface of the bidirectional threaded rod 16 are threadedly connected with threaded sleeves 19, and the front side and rear side of the threaded sleeve 19 are fixedly connected with a connecting rod 20, and the other end of the connecting rod 20 can be movably extended to the outside of the lifting box 12 and is fixedly connected with a connecting block 21.

[0021] The outer side of the connecting block 21 is rotatably connected to a push rod 22 via a torsion spring, the other end of the push rod 22 is fixedly connected to a rubber block 23, and the bottom of the outer side of the connecting block 21 is fixedly connected to a limiting protrusion 24 that limits the other end of the push rod 22 from tilting outward.

[0022] After the transmission mechanism drives the bidirectional threaded rod 16 to rotate, the two threaded sleeves 19 can be driven to move away from or towards each other, thereby adjusting the distance between the two push rods 22 at the same end. After the driving mechanism drives the lifting box 12 to descend, the other end of the push rod 22 can be driven to contact the end of the packaging bag on the surface of the pressure seat 14. By continuously descending the lifting box 12, the inclination angle can be changed by the push rod 22, and the end of the packaging bag can be pulled to move, thereby stretching the packaging bag, making it easier for the heat sealing block 13 to better seal the packaging bag.

[0023] The distance between the two push rods 22 can be changed, thereby facilitating the unfolding of irregular biodegradable packaging bags. The device has good adaptability and is beneficial to the production and processing of biodegradable packaging bags.

[0024] The driving mechanism includes two support plates 2, which are respectively fixedly connected to one end and the other end of the upper surface of the base plate 1, and a receiving box 3 is laterally fixedly connected between the opposite surfaces of the two support plates 2. A rotating rod 5 is rotatably arranged laterally in the inner cavity of the receiving box 3, and a transmission gear 6 is fixedly connected to the surface of the rotating rod 5.

[0025] One end of the rotating rod 5 extends to the outside of the storage box 3 and is fixedly connected to a pull rod 11. The inner cavity of the storage box 3 can be equipped with a vertical rod 7 that slides in the vertical direction. The bottom end of the vertical rod 7 can be pulled and extended to the outside of the storage box 3 and is fixedly connected to the top of the lifting box 12. The surface of the vertical rod 7 is fixedly connected to a rack plate 8 that meshes with the transmission gear 6.

[0026] When the staff changes the tilt angle by bending the pull rod 11, the rotating rod 5 can be driven to rotate, and after the rack plate 8 is driven to move by the transmission gear 6, the vertical rod 7 can be driven to be pulled and moved, and then the lifting box 12 can be driven to be lifted and moved.

[0027] The top end of the vertical rod 7 can be pulled out to extend to the outside of the storage box 3 and is fixedly connected to a top plate 9. A spring 10 covering the outside of the vertical rod 7 is vertically fixedly connected between the lower surface of the top plate 9 and the top of the storage box 3.

[0028] When the vertical rod 7 descends, the top plate 9 is driven down, and the extrusion spring 10 contracts to generate elastic force. When the staff releases the pull rod 11, the elastic force of the spring 10 can push the top plate 9 up, which is convenient for driving the lifting box 12 to reset.

[0029] The transmission mechanism includes a motor 15, which is fixedly connected to the middle part of the front side of the lifting box 12. The output shaft of the motor 15 can rotatably extend to the inner cavity of the lifting box 12 and is fixedly connected to a first bevel gear 17. The surface of the bidirectional threaded rod 16 is fixedly connected to a second bevel gear 18 that meshes with the first bevel gear 17.

[0030] After the motor 15 starts working, it can drive the first bevel gear 17 to rotate, and then through the transmission of the second bevel gear 18, it can drive the bidirectional threaded rod 16 to rotate.

[0031] Both ends of the front side surface and both ends of the rear side surface of the lifting box 12 are transversely provided with guide openings 4 for the connecting rod 20 to move.

[0032] The surface of the containing box 3 is provided with a maintenance box door which can be detached by a plurality of bolts, and the surface of the maintenance box door is provided with an observation window.

[0033] During operation, after the motor 15 works, it can drive the first bevel gear 17 to rotate, and then through the transmission of the second bevel gear 18, the bidirectional threaded rod 16 can be driven to rotate. After the bidirectional threaded rod 16 rotates, the two threaded sleeves 19 can be driven to move away from or close to each other, thereby adjusting the distance between the two push rods 22 at both ends of the same side. After the staff changes the inclination angle by bending the pull rod 11, the rotating rod 5 can be driven to rotate. After the rack plate 8 is driven to move by the transmission gear 6, the vertical rod 7 can be driven to pull and move, thereby driving the lifting box 12 to lift and move. When the lifting box 12 is driven to descend, the other end of the push rod 22 can be driven to contact the end of the packaging bag on the surface of the pressure seat 14. Through the continuous descent of the lifting box 12, the inclination angle can be changed by the push rod 22, and the end of the packaging bag can be pulled to move, thereby stretching the packaging bag, which is convenient for the heat sealing block 13 to better seal the packaging bag. By being able to change the distance between the two push rods 22, it is convenient to unfold irregular biodegradable packaging bags.
