Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, and in particular relates to an anti-wrinkle blanket roller for blanket conveying. Background Technology

[0002] In the production, processing, and finishing of blankets, the blanket conveying process directly affects the final product quality. Currently, most blanket conveyor rollers on the market use ordinary conveyor belts with simple limiting structures. The conveyor belt surface is often a flat, rough structure, which, while increasing friction to some extent, makes the blanket prone to lateral shifting or longitudinal wrinkling when conveyed at high speeds or under uneven stress. Furthermore, the limiting components lack coordinated design with the conveyor belt, relying solely on a single limiting ring for edge restraint, failing to address wrinkling issues in the central area of ​​the blanket. Additionally, the limiting structure is often integrally molded with the limiting roller, requiring complete disassembly and replacement when worn, resulting in high maintenance costs and reduced production efficiency. These problems lead to surface wrinkles and uneven edges during blanket conveying, reducing product yield and increasing subsequent rework costs. Therefore, there is an urgent need for a blanket conveyor roller structure that can effectively prevent wrinkles and deviations and is easy to maintain. Utility Model Content

[0003] The present invention aims to provide a wrinkle-resistant blanket roller for blanket conveying, so as to solve the problems of easy wrinkling, easy deviation and inconvenient maintenance of blankets in the prior art.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: it includes a conveyor roller assembly and a limiting roller. The conveyor roller assembly consists of at least two rollers and is fitted with a rubber conveyor belt on its outer side. The surface of the conveyor belt is roughened to increase friction. Several arc-shaped protrusions made of rubber are fixedly arranged on the surface of the conveyor belt. The direction of the arc-shaped protrusions is perpendicular to the direction of the conveyor roller assembly. A limiting component is fitted on the outer side of the limiting roller. The limiting component includes several limiting rings arranged in an array. Several auxiliary limiting rods are arranged in an array around an axis between adjacent limiting rings. Annular connectors are provided on the outer sides of the two limiting rings at both ends for connecting with the limiting roller. The number and vertical position of the arc-shaped protrusions correspond to those of the limiting rings.

[0005] Furthermore, the bottom width of the arc-shaped protrusion cross-section is equal to the width of the limiting ring.

[0006] Furthermore, the uniform width design minimizes the probability of the blanket shifting during linear displacement due to differences in the width of the components applying pressure from above and below.

[0007] Furthermore, the limiting ring has a trapezoidal groove in the middle, and the depth of the groove exceeds the arc height of the arc-shaped protrusion.

[0008] Furthermore, the arc-shaped protrusions partially lift the blanket and press it into the groove, creating a simulated track transport effect in conjunction with the linear forward movement.

[0009] Furthermore, the inner side of the auxiliary limiting rod is an arc-shaped concave surface that fits against the outer surface of the limiting roller, and the auxiliary limiting rod is welded to the limiting rings at both ends. The height of the auxiliary limiting rod is lower than the height of the limiting rings.

[0010] Furthermore, the auxiliary limiting rod applies slightly less pressure to the area outside the arc-shaped protrusion and the limiting ring, so as to bring the blanket as close to the conveyor belt as possible, reducing gaps and avoiding wrinkles.

[0011] Furthermore, the annular connector is provided with a plurality of connecting ears arranged in an array, and the connecting ears are connected to the limiting roller by screws, and the annular connector is welded to the limiting ring.

[0012] Furthermore, the limiting component is directly fitted onto the outside of the limiting roller and connected through the connecting lugs located at the outermost ends of the limiting component. During maintenance, the limiting component can be directly disassembled and replaced, reducing maintenance costs.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the corresponding cooperation between the arc-shaped protrusion and the limiting ring, combined with the groove, forms a simulated track-type conveying structure to limit the lateral displacement of the blanket; the equal width design avoids the offset caused by the difference in width of the pressure component, and the auxiliary limiting rod reduces the gap between the blanket and the conveyor belt, preventing wrinkles from occurring in multiple dimensions. 2. In this utility model, both the conveyor belt and the arc-shaped protrusion are made of rubber, and with the roughening treatment, the friction can be improved and the carpet surface can be avoided from being scratched, thus ensuring the integrity of the product's appearance. 3. In this utility model, the limiting component is detachably connected to the limiting roller via a connecting ear. It can be directly disassembled and replaced after wear, without the need to completely disassemble the conveyor roller, thus reducing maintenance time and cost. 4. In this utility model, the components are welded and bolted together, resulting in high structural strength; the number of arc-shaped protrusions and limiting rings can be adjusted according to different widths of blankets to meet the conveying needs of various product specifications.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Combination Figures 1 to 5 The invention illustrates an anti-wrinkle blanket roller for blanket conveying, comprising a conveyor roller assembly 1 and a limiting roller 2. The conveyor roller assembly 1 consists of at least two rollers, and a rubber conveyor belt 3 is sleeved on its outer side. The surface of the conveyor belt 3 is roughened to increase friction. Several arc-shaped protrusions 31 made of rubber are fixedly arranged on the surface of the conveyor belt 3. The direction of the arc-shaped protrusions 31 is perpendicular to the direction of the conveyor roller assembly 1. A limiting component 21 is sleeved on the outer side of the limiting roller 2. The limiting component 21 includes several limiting rings 211 arranged in an array. Several auxiliary limiting rods 212 are arranged in an array around the axis between adjacent limiting rings 211. Annular connectors 213 are provided on the outer side of the two limiting rings 211 at both ends for connecting with the limiting roller 2. The number and vertical position of the arc-shaped protrusions 31 and the limiting rings 211 are corresponding.

[0018] The bottom width of the arc-shaped protrusion 31 is equal to the width of the limiting ring 211.

[0019] The uniform width design minimizes the probability of the blanket shifting during linear displacement due to differences in the width of the components applying pressure from above and below.

[0020] The limiting ring 211 has a trapezoidal groove 214 in the middle, and the depth of the groove 214 exceeds the arc height of the arc protrusion.

[0021] The arc-shaped protrusions lift and press the blanket into the groove 214, creating a simulated track transport effect in conjunction with the linear forward movement.

[0022] The inner side of the auxiliary limiting rod 212 is an arc-shaped concave surface that fits against the outer surface of the limiting roller 2, and the auxiliary limiting rod 212 is welded to the limiting rings 211 at both ends. The height of the auxiliary limiting rod 212 is lower than the height of the limiting rings 211.

[0023] The auxiliary limiting rod 212 applies a small amount of pressure to the area outside the arc-shaped protrusion 31 and the limiting ring 211, so as to make the blanket as close to the conveyor belt 3 as possible, reduce gaps and avoid wrinkles.

[0024] The annular connector 213 is provided with a plurality of connecting ears 215 arranged in an array, and the connecting ears 215 are connected to the limiting roller 2 by screws. The annular connector 213 is welded to the limiting ring 211.

[0025] The limiting component 21 is directly sleeved on the outside of the limiting roller 2 and connected through the connecting ears 215 located at the outermost ends of the limiting component 21. During maintenance, the limiting component 21 can be directly disassembled and replaced, reducing maintenance costs.

[0026] Working principle: During use, the limiting component 21 is fixed to the outside of the limiting roller 2 through the connecting ear 215 of the ring connector 213, ensuring that the arc-shaped protrusion 31 is vertically aligned with the limiting ring 211. The distance between the conveying roller group 1 and the limiting roller 2 is adjusted so that the fitting gap between the arc-shaped protrusion 31 and the groove 214 is 1-5mm. The distance between the auxiliary limiting rod 212 and the conveyor belt 3 is 2-3mm to adapt to the thickness of the blanket. The blanket to be conveyed is laid flat on the surface of the conveyor belt 3, and the conveyor roller group 1 is started to drive the conveyor belt 3 to move linearly. The arc-shaped protrusion 31 lifts the blanket locally and embeds it into the groove 214 of the limiting ring 211 to form a multi-point positioning guide, which restricts the lateral displacement of the blanket. The auxiliary limiting rod 212 applies slight pressure to the non-positioning area of ​​the blanket, so that the blanket fits tightly against the conveyor belt 3 and avoids wrinkles caused by airflow or vibration. As the conveyor belt 3 continues to move, the blanket is smoothly conveyed under the track constraint, and finally wrinkle-free conveying is achieved.
