DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 7 As shown, the technical solution adopted by the present invention is as follows: In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: A roller spacing adjustment component, comprising: a support column 1, a connecting component, a supporting component and an adjusting member. There are two support columns 1, and the two support columns 1 are symmetrically arranged. A sliding hole 6 is provided on the support column 1, and the connecting component is slidably arranged in the sliding hole 6. A sliding groove 9 is provided at the lower part of the sliding hole 6, and the supporting component is slidably arranged in the sliding groove 9, and the supporting component cooperates with the connecting component to support the connecting component so that the connecting component can work stably. A through hole is provided on the support column 1, and the through hole is connected to the sliding hole 6. The adjusting member is threadedly connected to the through hole, and the lower end of the adjusting member cooperates with the connecting component. The connecting component can slide in the sliding hole 6 through the adjusting member, thereby completing the adjustment of the connecting component. The adjusting member is threadedly connected to the supporting component, and when the adjusting member adjusts the connecting component, it will drive the supporting component to support the connecting component, and the supporting component always maintains the support for the connecting component.

[0038] The connecting assembly includes: a connecting block 5 and a rotating shaft 4. The connecting block 5 is slidably arranged in a sliding hole 6, and the upper part of the connecting block 5 cooperates with an adjusting member. A connecting hole is provided in the middle of the connecting block 5, and the two ends of the rotating shaft 4 are rotatably connected in the corresponding connecting holes respectively. An upper roller 3 is fixedly sleeved on the outer circumference of the rotating shaft 4. A lower roller 2 is rotatably connected between the two support columns 1, and the lower roller 2 is located below the upper roller 3. The roller gap can be adjusted by driving the upper roller 3 to move up and down through the adjusting member by the connecting block 5. The chamfers are symmetrically arranged on the lower part of the connecting block 5, and the chamfers cooperate with the supporting assembly, so that the supporting assembly can support the connecting block 5 and keep the upper roller 3 in a stable working state.

[0039] The support assembly includes: a triangular block 7, a spring 10 and a push rod 11. The triangular block 7 has two pieces, and the two triangular blocks 7 are respectively slidably arranged on both sides of the connecting block 5, and one inclined surface of the triangular block 7 is matched with the corresponding chamfer on the connecting block 5. The triangular block 7 supports the connecting block 5 by using the inclined surface of the triangular block 7 and the chamfer of the lower part of the connecting block 5. The lower part of the triangular block 7 is fixedly connected with a slider 8, and the slider 8 is slidably arranged in the slide groove 9. The spring 10 is fixedly connected in the slide groove 9, one end of the spring 10 is fixedly connected to the slider 8, and the other end of the spring 10 is fixedly connected to the inner wall of the slide groove 9. The spring 10 maintains tension on the triangular block 7 through the slider 8, so that when the triangular block 7 is away from the connecting block 5, the connecting block 5 can drive the upper roller 3 to drop to the state where the roller spacing is the smallest. The push rod 11 is slidably arranged in the support column 1, and the push rod 11 is a "U"-shaped structure. A ring is fixedly arranged in the middle of the "U"-shaped structure, and the ring is threadedly connected to the adjusting member. Both ends of the push rod 11 are arranged as inclined surfaces, which cooperate with the inclined surface of the triangular block 7 away from the connecting block 5. When the adjusting member moves upward, the push rod 11 moves downward, and the push rod 11 pushes the triangular block 7 to move toward the connecting block 5, and pushes the connecting block 5 to move upward, thereby increasing the distance between the upper roller 3 and the lower roller 2, and vice versa, the roller distance becomes smaller.

[0040] The adjusting member includes: a first threaded rod 12 and a second threaded rod 13. The first threaded rod 12 is threadedly connected in the through hole, and the ring in the middle of the push rod 11 is threadedly connected to the first threaded rod 12. The lower end of the first threaded rod 12 cooperates with the connecting block 5. The second threaded rod 13 is threadedly connected inside the first threaded rod 12, and a rotating handle 14 is fixedly provided on the top of the first threaded rod 12, and a rotating handle 15 is fixedly provided on the upper end of the second threaded rod 13. The first threaded rod 12 is rotated by rotating the rotating handle 14, and the first threaded rod 12 pushes the connecting block 5 downward, so that the connecting block 5 drives the upper roller 3 to move downward, which plays a role in reducing the roller spacing. At the same time, the push rod 11 moves upward under the drive of the first threaded rod 12, and the push rod 11 gradually reduces the thrust on the triangular block 7 when it moves upward, so that the triangular block 7 moves away from the connecting block 5 under the action of the spring 10, thereby ensuring that the connecting block 5 can move downward smoothly, and at the same time ensuring that the triangular block 7 always supports the connecting block 5. After the roller spacing is adjusted, the second threaded rod 13 can be rotated by turning the handle 15, and the second threaded rod 13 moves in the first threaded rod 12, thereby completing the fine adjustment of the roller spacing. The control of the roller spacing is more accurate. And because the fine adjustment distance is small, it will not affect the support of the triangular block 7 to the connecting block 5, so after the fine adjustment, the triangular block 7 can still maintain the support for the connecting block 5, so that the connecting block 5 remains in a stable state.

[0041] like Figure 8As shown, the present invention also proposes a fully automatic high-speed bag-making machine, which includes the roller spacing adjustment assembly described above. The specific structure of the roller spacing adjustment assembly refers to the above embodiment. Since the fully automatic high-speed bag-making machine proposed by the present invention includes all implementation schemes of the above roller spacing adjustment assembly, it has at least the same technical effect as the roller spacing adjustment assembly, which will not be described one by one here.

[0042] Working principle: When in use, the roller spacing is adjusted according to the thickness of the bag to be made. If the roller spacing needs to be increased, the rotating handle 14 is turned, and the rotating handle 14 drives the first threaded rod 12 to rotate. Since the first threaded rod 12 is threadedly connected in the through hole, the first threaded rod 12 will move upward. Since the middle part of the push rod 11 is threadedly connected to the first threaded rod 12, and the push rod 11 is slidably set in the support column 1, the rotation of the first threaded rod 12 will drive the push rod 11 to move downward. When the push rod 11 moves downward, the inclined surface of the lower end of the push rod 11 squeezes the triangular block 7, so that the triangular block 7 moves toward the direction of the connecting block 5, so that the triangular block 7 pushes the connecting block 5 upward through the chamfer below the connecting block 5, and the connecting block 5 rises in the sliding hole 6, which drives the upper roller 3 to rise, and the lower roller 2 remains stationary to achieve the increase of the roller spacing. Then, according to actual needs, the second threaded rod 13 is rotated by turning the handle 15, so that the lower end of the second threaded rod 13 contacts the connecting block 5, and the connecting block 5 is finely adjusted, so that the roller spacing is further controlled more accurately, and the transmission of plastic bags is prevented or invalid due to inaccurate roller spacing control. And because the fine-tuning distance is small, it will not affect the support of the triangular block 7 to the connecting block 5, so after fine-tuning, the triangular block 7 can still maintain the support for the connecting block 5, so that the connecting block 5 remains stable.

[0043] If the roller spacing needs to be reduced, the rotating handle 14 is rotated in the opposite direction to drive the first threaded rod 12 to rotate by rotating the rotating handle 14, and the first threaded rod 12 pushes the connecting block 5 downward, so that the connecting block 5 drives the upper roller 3 to move downward, thereby reducing the roller spacing. At the same time, the push rod 11 moves upward under the drive of the first threaded rod 12, and the push rod 11 gradually reduces the thrust on the triangular block 7 when moving upward, so that the triangular block 7 moves away from the connecting block 5 under the action of the spring 10, thereby ensuring that the connecting block 5 can move downward smoothly, and at the same time ensuring that the triangular block 7 always supports the connecting block 5. After adjusting the roller spacing, the second threaded rod 13 can be rotated by turning the handle 15, and the second threaded rod 13 moves in the first threaded rod 12, thereby completing the fine adjustment of the roller spacing. Make the control of the roller spacing more accurate. Then start the fully automatic high-speed bag making machine for production.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
