[0022] This utility model proposes a pressing mechanism for a garbage bag packaging device.

[0023] In this embodiment of the utility model, such as Figures 1 to 3 As shown, the pressing mechanism for the garbage bag packing device includes a base 1, a first pressing member 2, and a second pressing member 3. The base 1 and the first pressing member 2 are respectively fixedly installed on the garbage bag packing device, forming a left-right or front-back interval so that the garbage bag on the garbage bag packing device passes through the base 1 and the first pressing member 2 from top to bottom. The base 1 and the first pressing member 2 are connected by a guide rod 4. The second pressing member 3 is movably sleeved on the guide rod and can move along the guide rod 4 between abutting against the first pressing member 2 to partially press the garbage bag and moving away from it. The base 1 is also provided with a drive motor 5. The second pressing member 3 is fixedly connected to a rack 61. The rack 61 cooperates with the rotating end of the drive motor 5 so that the rotation of the rotating end of the drive motor 5 drives the second pressing member 3 to perform the movement.

[0024] Specifically, the rotating end of the drive motor 5 directly meshes with the rack 61.

[0025] Specifically, the base 1 has a guide hole 13 for the rack 61 to pass through, and the shape of the guide hole 13 is adapted to the cross-section of the rack 61. The guide hole 13 is relatively compact, which makes it less likely for the rack 61 to shake and produce abnormal noise during the process of passing through the guide hole 13, and also helps the drive motor 5 to drive the rack 61 smoothly.

[0026] Specifically, the base 1 is a plastic product.

[0027] Specifically, the second pressing member 3 is directly fixedly connected to one end of the rack 61, or, in order to increase the connection area between the end of the rack 61 and the second pressing member 3 and balance the pressure at various positions when the first pressing member 2 and the second pressing member 3 are pressed together, a plate-shaped connecting member 7 is also provided. The connecting member 7 is fixedly connected to one end of the rack 61, and the second pressing member 3 is fixedly connected to the connecting member 7.

[0028] Specifically, one end of the rack 61 is provided with a positioning block 611, and the connecting member 7 is provided with a groove that matches the positioning block 611. After the positioning block 611 is inserted into the groove, it is locked by screws. The second pressing member 3 is locked to the connecting member 7 by screws.

[0029] Specifically, the first pressing member 2 and the second pressing member 3 are plate-shaped structures.

[0030] Specifically, the first pressing member 2 and the second pressing member 3 are respectively fixed with a first pressing strip 8 and a second pressing strip 9. The second pressing member 3 can move along the guide rod 4 between positions where the first pressing strip 8 and the second pressing strip 9 abut and positions where they move away from each other, so as to partially press the garbage bag together by the abutment of the first pressing strip 8 and the second pressing strip 9. The first pressing strip 8 and the second pressing strip 9 are fixed to the first pressing member 2 and the second pressing member 3 respectively with glue.

[0031] Specifically, the base 1 and the first pressing member 2 are connected by two guide rods 4. The second pressing member 3 has a sliding sleeve 31 at a position adjacent to the end wall of the second pressing strip 9. The two sliding sleeves 31 are respectively movably sleeved on the two guide rods 4. The first pressing member 2 has a relief groove 21 at the position corresponding to the sliding sleeve 31, allowing the sliding sleeve 31 to be partially inserted. When the first pressing strip 8 and the second pressing strip 9 abut, the sliding sleeve 31 is partially inserted into the relief groove 21. During the pressing process, there is a possibility that the garbage bag may partially extend beyond the end wall of the second pressing strip 9, resulting in incomplete pressing. To address this issue, the sliding sleeve 31 adjacent to the end wall of the second pressing strip 9 can be used to prevent the garbage bag from extending beyond the end wall of the second pressing strip 9. On the other hand, even if a portion of the garbage bag extends beyond the end wall of the second pressure strip 9 and is not pressed, the unpressed portion of the garbage bag can be folded by the sliding sleeve 31 during the process of inserting the sliding sleeve 31 into the relief groove 21 to avoid incomplete pressing. When the end wall of the first pressure strip 8 is located in the relief groove 21, the sliding sleeve 31 forces the folded portion of the garbage bag to abut against the end wall of the first pressure strip 8. When the end wall of the first pressure strip 8 is not located in the relief groove 21, the sliding sleeve 31 forces the folded portion of the garbage bag to abut against the inner wall of the relief groove 21.

[0032] Specifically, the first pressure strip 8 and the second pressure strip 9 are made of rubber or silicone.

[0033] It should be noted that the garbage bag packaging device can refer to the technical solution disclosed in patent publication number CN116620662A. It can be an automatic vacuum packaging device in the field of cat litter box technology, an automatic vacuum packaging device in the field of garbage can technology, or an automatic vacuum packaging device in other technical fields.

[0034] This utility model includes a base, a first pressing member, and a second pressing member. The base and the first pressing member are connected by a guide rod to form left-right or front-back intervals. The second pressing member is movably sleeved on a guide rail and is equipped with a rack fixedly connected to it. A drive motor is mounted on the base. The rotating end of the drive motor cooperates with the rack, so that when the rotating end of the drive motor rotates, it drives the second pressing member to move towards or away from the first pressing member. During installation, the base and the first pressing member are fixedly installed on a garbage bag baling device, allowing the garbage bag on the baling device to pass through the space between the base and the first pressing member from top to bottom. During operation, the movement of the second pressing member towards the first pressing member can partially gather and compress the garbage bag, while the movement of the second pressing member away from the first pressing member can release the garbage bag. Compared with traditional methods, the modular design of this utility model offers advantages such as simple structure and convenient installation, and the single rack drive structure effectively achieves low-noise or zero-noise operation.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
