Description

Technical Field

[0001] The utility model relates to the technical field of synthetic leather production, in particular to a rolling mechanism for synthetic leather production. Background Technique

[0002] Polyurethane synthetic leather belongs to a kind of polyurethane elastomer. Polyurethane synthetic leather itself has the appearance advantages of soft luster and strong real leather feeling, and also has excellent mechanical properties such as excellent adhesion performance with the base material, abrasion resistance, flexure resistance, and anti-aging. It has gradually become an ideal substitute for natural leather. When processing polyurethane synthetic leather, rolling processing is required, so a rolling mechanism needs to be used.

[0003] After retrieval, the Chinese patent publication number: CN218577247U discloses a rolling mechanism for synthetic leather production, including two end plates. A fixed pressure roller is fixedly connected between the two end plates. At least one strip-shaped arc groove is axially opened on the outer side wall of the fixed pressure roller. A moving pressure roller is fitted in the strip-shaped arc groove. Both ends of the moving pressure roller are rotatably connected with sliders, and the sliders are elastically slidably connected with the adjacent end plates; by opening a strip-shaped arc groove on the outer side of the fixed pressure roller and using the elastic extrusion of the moving pressure roller, the synthetic leather passes through between the moving pressure roller and the strip-shaped arc groove, improving the contact area between the moving pressure roller and the synthetic leather, improving the rolling effect of the synthetic leather, making the synthetic leather closely fit, and ensuring the production quality of the synthetic leather.

[0004] Although the existing rolling mechanism improves the contact area between the moving pressure roller and the synthetic leather and the rolling effect of the synthetic leather, there are still some deficiencies. Since each batch of synthetic leather is produced according to the needs of customers, the widths of the synthetic leather are quite different. However, the existing rolling mechanism usually cannot be adjusted according to the width of the synthetic leather. If the width of the pressing roller at the bottom of the rolling mechanism is short, it will cause the rolling mechanism to not fully cover the wider synthetic leather. Therefore, the pressing roller needs to be replaced, which will reduce the production efficiency of the synthetic leather. If the length of the pressing roller is long, it cannot limit the synthetic leather during transportation, and it is easy to cause the synthetic leather to tilt during transportation, which will reduce the rolling effect of the synthetic leather and affect the subsequent work of winding the synthetic leather. For this reason, a rolling mechanism for synthetic leather production is proposed to solve the above problems. Summary of the Utility Model

The sliders 8 can be limited by the sliding grooves 16, so as to prevent the sliders 8 from tilting during the movement process, and the sliders 8 can only perform smooth translational sliding, and at the same time, the movable blocks 9 can be driven to perform translational movement.

[0032] Referring to Figures 1 - 3 , a pressing roller 10 is slidably connected to the middle of the two movable blocks 9. The use width of the pressing roller 10 can be adjusted while the two movable blocks 9 approach or move away from each other. By driving the motor 5, the gear 6 can rotate forward or backward. At the same time, when the gear 6 rotates, the two rack plates 7 can be driven to move. When the rack plates 7 move, the two sliders 8 can drive the two movable blocks 9 to approach or move away from each other. At this time, the use width of the pressing roller 10 can be adjusted, so that the pressing roller 10 can transport synthetic leather with different widths, and at the same time, synthetic leather with different widths can be restricted to prevent the synthetic leather from tilting during the transportation process, which can improve the rolling effect and facilitate the subsequent work of winding the synthetic leather. A connection component is arranged between the movable block 9 and the pressing roller 10.

A pull ring is fixedly connected to the outside of the pull rod 13. The pull rod 13 can be pulled more conveniently and comfortably through the pull ring.

[0037] Working principle: The driving motor 5 can drive the gear 6 to rotate. When the gear 6 rotates, the two rack plates 7 can be moved simultaneously. When the rack plates 7 move, the slider 8 and the movable block 9 can be moved simultaneously. At this time, the use range of the pressing roller 10 can be adjusted, so that the pressing roller 10 can transport synthetic leather with different widths, and at the same time, synthetic leather with different widths can be restricted to prevent the synthetic leather from tilting during transportation;

[0038] Among them, by inserting the pressing rod 10 into the movable block 9, when the pressing rod 10 enters, it will squeeze the baffle 12 and cause the baffle 12 to compress the first compression spring 11. At this time, the pressing rod 10 can be completely inserted into the movable block 9. After the pressing rod 10 enters, the baffle 12 can be ejected by the first compression spring 11. At this time, the pressing rod 10 can be squeezed and the pressing rod 10 can be in contact with the movable block 9. At this time, the problem of the pressing rod 10 falling off can be prevented. When the pressing rod 10 needs to be removed, by pulling the pull rod 13, the baffle 12 can be driven to compress the first compression spring 11, and at the same time, the restriction on the pressing rod 10 can be released, and then the pressing rod 10 can be replaced. At the same time, it is convenient to clean and maintain the replaced pressing rod 10.
