Description

Technical Field

[0001] This utility model specifically relates to a trolley for taking up ultra-soft padding adhesive and its padding cloth. Background Technology

[0002] As a key adhesive for tire carcass bonding, the liner rubber is placed on the shoulder of the carcass to help the tread smoothly transition to the sidewall and absorb rolling stress. The accuracy of its triangular cross-section is crucial to tire quality. However, the traditional method has significant drawbacks: the material roll experiences interlayer compression due to gravity, causing deformation of the liner rubber's triangular cross-section, unclear edges, and relative slippage between the rubber and the liner cloth, affecting the tire forming benchmark. The traditional triangular guide roller layout easily causes surface tensile cracks and cross-sectional angle deviations for ultra-soft liner rubber with a Shore hardness below A40. To prevent deformation, thin stainless steel sheet liner cloth is used, but this leads to a significant increase in the size and weight of the material cart, not only occupying a large area and making transportation and material changing difficult, but also causing storage costs to soar, restricting production efficiency and the progress of intelligent manufacturing. Utility Model Content

[0003] This utility model provides a trolley for winding up ultra-soft rubber pads, the trolley comprising:

[0004] Frame;

[0005] A first drive shaft and a second drive shaft are arranged parallel to each other on the frame, with the height of the first drive shaft being greater than that of the second drive shaft;

[0006] A first I-beam wheel is fitted onto a first drive shaft and a second I-beam wheel is fitted onto a second drive shaft. The ends of the first drive shaft and the second drive shaft are connected to a first chuck and a second chuck that are arranged in the same direction.

[0007] Multiple passive guide rollers are mounted parallel to each other on the frame from front to back and are on the same horizontal mounting plane.

[0008] In some embodiments, multiple sponge protrusions are spaced apart on the surface of the pad, and the protrusions extend along the length of the pad and are evenly distributed.

[0009] In some embodiments, the first I-beam is adapted to wind up a pad with adhesive backing, and the second I-beam is adapted to wind up a guided pad.

[0010] In some embodiments, the padding cloth has three sponge protrusions evenly spaced on it, located on the left and right sides and in the middle of the padding cloth, respectively.

[0011] In some embodiments, the sponge protrusions are open-cell polyurethane sponges.

[0012] In some implementations, multiple passive guide rollers are rotatably connected to the frame via bearings.

[0013] This utility model also provides a pad suitable for padding adhesive, the surface of which is provided with multiple sponge protrusions at intervals, the sponge protrusions extending along the length of the pad and evenly arranged longitudinally.

[0015] In some embodiments, the padding cloth has three sponge protrusions evenly spaced on it, located on the left and right sides and in the middle of the padding cloth, respectively.

[0016] This invention addresses the deformation problem of ultra-soft rubber pads by using coplanar guide rollers and sponge convex strip pads, overcoming the drawbacks of traditional stainless steel pad solutions in terms of volume, weight, and cost.

[0018] Figure 2 A schematic diagram of the structure of the trolley (with padding) provided by this utility model. Detailed Implementation

[0019] Please see Figure 1 and Figure 2 This embodiment provides a trolley for winding ultra-soft padding adhesive, including an anti-deformation trolley; the anti-deformation trolley includes a frame 1, a first drive shaft 2 and a second drive shaft 3 arranged parallel to the frame, a first I-beam wheel 4 mounted on the first drive shaft and a second I-beam wheel 5 mounted on the second drive shaft, and a first chuck 6 and a second chuck 7 arranged in the same direction connected to the ends of the first drive shaft 2 and the second drive shaft 3; the height of the first drive shaft 2 is greater than that of the second drive shaft 3.

[0020] In this embodiment, the first I-beam is wound with a padding cloth with adhesive, the second I-beam is adapted to wind the unwound padding cloth, the second chuck is adapted to be connected to a drive motor, and the first chuck is adapted to be connected to a brake, such as a magnetic powder brake. The rotation of the second I-beam drives the material of the first I-beam to be unwound.

[0021] Because the padding material in this embodiment is highly flexible, the trolley also includes multiple passive guide rollers 71, 72, 73, and 74. These passive guide rollers are installed parallel to each other on the frame from front to back and are on the same horizontal mounting plane, forming a seamless material path. The passive guide rollers 71, 72, 73, and 74 are passively rotatably connected to the frame via bearings. After the padding material, guided by the first I-beam, is smoothly conveyed through the multiple parallel guide rollers, the padding material is conveyed towards the feed end directly in front. The guided padding material is then guided to the second I-beam for winding. The high-low dual-drive shaft layout, combined with the multiple passive guide rollers, ensures that the guided padding material smoothly transitions through the parallel guide roller group, forming a material flow path of low-level guidance, horizontal conveying, and high-level winding, effectively preventing the material from folding and being squeezed. Compared to existing technologies (such as the winding carriage disclosed in CN114735508B, which is mainly suitable for padding rubber with higher hardness), the fully coplanar guide roller group can ensure the smooth turning of the padding cloth while completely eliminating the folding risk and tensile stress caused by the traditional triangular layout to the highly flexible padding rubber. It is particularly suitable for the processing needs of ultra-soft padding rubber for new energy vehicles.

[0022] Detailed Explanation of the Working Process of the Rubber Roll Take-up Cart (with Appendix) Figure 1 , 2 (Structure shown)

[0023] 1. Initial State

[0024] The first I-beam (material wheel) 4 is mounted on the first drive shaft 2 at a high position and winds the padding cloth with rubber padding (initially full roll); the second I-beam (pad roll) 5 is mounted on the second drive shaft 3 at a low position in an empty roll state; the guide roller groups 71, 72, 73, and 74 are arranged horizontally in a coplanar manner to form a conveying plane with no height difference;

[0025] 2. Opening Phase

[0026] The drive motor drives the second transmission shaft 3 to rotate via the second chuck 7, causing the padding wheel 5 to rotate actively and the material wheel 4 to be passively guided away.

[0027] 3. Pad cloth guides away

[0028] The rubberized pad on material wheel 4 is discharged tangentially and enters the horizontal conveyor section (between guide rollers 71-72).

[0029] 4. Pad peeling and conveying

[0030] The padding adhesive is peeled off from the padding cloth and output horizontally to the front feeding end; the padding cloth continues to be wound backward and downward on the padding cloth wheel.

[0031] Furthermore, the pad 8 provided by this utility model has multiple sponge protrusions 81 spaced apart on its surface. These sponge protrusions 81 extend along the length of the pad 8 and are evenly distributed longitudinally along the pad, forming an elastic buffer space between layers. This avoids the rigid compression of the adhesive by traditional steel plate pads and overcomes the shortcomings of insufficient support from soft materials. This structure can adapt to the deformation of the adhesive, continuously providing flexible support during winding and unwinding, ensuring the integrity of the adhesive's cross-sectional shape. Compared to metal pads, the sponge material significantly reduces weight and better conforms to the properties of the adhesive, protecting the shape of the adhesive. In addition, the sponge is compressible and resilient, automatically adapting to fluctuations in the thickness of the adhesive.

[0032] The padding fabric has three evenly spaced sponge protrusions, located on the left and right sides and in the middle. Optionally, the sponge protrusions are made of open-cell polyurethane sponge. The open-cell structure allows for free air circulation, which avoids the instability caused by closed-cell sponge and prevents the padding adhesive from sticking to the padding fabric.
