Description

Technical Field

[0001] This utility model relates to the field of textile rollers, and more specifically, it relates to a rubber roller that is easy to repair. Background Technology

[0002] Rubber rollers are roller-shaped products made by vulcanizing rubber with a metal or other material core. They are also widely used in textile machinery.

[0003] During use, the rubber layer covering the rubber roller may be scratched. To save costs, the rubber layer of the rubber roller is repaired. Currently, repair adhesive is used to repair the scratched area of ​​the rubber layer, and then a trowel is used to smooth it. Finally, the repair adhesive is allowed to cure completely. Since the repair adhesive requires a certain temperature and time to cure, the rubber roller needs to be removed and repaired in a location with a suitable temperature. However, since the rubber roller is cylindrical, if it is placed directly on a platform for repair, the rubber roller is prone to rolling, which affects the repair operation.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rubber roller that is easy to repair.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a repairable rubber roller, comprising a roller body, roller shafts at both ends of the roller body, a rectangular block between the roller body and the roller shafts, a receiving groove and two circular grooves on the side of the rectangular block facing the roller shafts, a support plate in the receiving groove, a support rod in the circular grooves, two threaded holes on each of the four outer side walls of the rectangular block, a threaded post at one end of the support rod for connecting to the threaded hole, and two snap-fit ​​holes on the support plate.

[0007] The present invention is further configured such that: the support plate includes a main board and two rotating plates located on both sides of the main board, the two rotating plates can only rotate toward each other and the maximum rotation angle is 90 degrees, the cross-section of the receiving groove is C-shaped, and the two snap-fit ​​holes are respectively located on the two rotating plates.

[0008] The present invention is further configured such that: a torsion spring is provided between the main board and the rotating plate, and when the torsion spring is in its natural state, one side of the rotating plate is flush with the main board.

[0009] The present invention is further configured such that: a rubber ring is provided on the side of the support rod facing away from the threaded column, and the depth of the circular groove is equal to the length of the support rod.

[0010] The present invention is further configured such that: the rectangular block is provided with a plurality of slots communicating with the receiving groove.

[0011] The present invention is further configured such that rubber strips are provided on both sides of the rotating plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The support rod and support plate are removed from the roller body. After unfolding the support plate, one end of the support rod connects to the snap-fit ​​hole of the support plate, and the other end of the support rod connects to the threaded hole of the rectangular block. By setting up the support plate and support rod, the roller body can be supported, so that the roller body is supported as a whole and the roller body will not rotate. The threaded holes are on the four side walls of the rectangular block, so that people can determine the point where the support rod needs to be supported according to the location of the cut in the rubber layer, so as to ensure that the cut position is relatively upward and convenient for repair.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A type of rubber roller that is easy to repair, such as Figure 1 and Figure 2As shown, the device includes a roller body 1, with a rubber layer on its outer peripheral wall. Roller shafts 2 are located at both ends of the roller body 1. A rectangular block 3 is positioned between the roller body 1 and the roller shafts 2. The rectangular block 3 has a receiving groove 4 and two circular grooves 5 on the side facing the roller shafts 2. A support plate is located within the receiving groove 4, and a support rod 6 is located within the circular grooves 5. Two threaded holes 13 are located on each of the four outer side walls of the rectangular block 3. One end of the support rod 6 has a threaded post 7 for connecting to the threaded hole 13. Two snap-fit ​​holes 8 are located on the support plate. In normal operation, the support plate is located in the receiving groove 4, and the support rod 6 is located in the circular grooves 5. The friction between the support rod 6 and the circular grooves 5 prevents the support rod 6 from easily disengaging from the circular grooves 5 during the rotation of the roller body 1. This structure is suitable for rubber rollers with relatively large diameters and relatively high angular velocities. The support rod 6 is relatively small, and the direction of its movement away from the circular groove 5 is not the same as the centrifugal direction, making it difficult for the support rod 6 to detach from the circular groove 5, and the support plate to detach from the receiving groove 4. When it is necessary to repair the rubber layer on the outer peripheral wall of the roller body 1, the support rod 6 and the support plate are removed from the roller body 1 respectively. After unfolding the support plate, one end of the support rod 6 is connected to the snap-fit ​​hole 8 of the support plate, and the other end of the support rod 6 is connected to the threaded hole 13 of the rectangular block 3. By setting the support plate and the support rod 6, the roller body 1 can be supported, so that the roller body 1 is supported as a whole, thus preventing the roller body 1 from rotating. The threaded hole 13 is on the four side walls of the rectangular block 3, so that people can determine the point where the support rod 6 needs to be supported according to the location of the cut in the rubber layer, ensuring that the cut position is relatively upward, which is convenient for people to repair.

[0019] like Figure 1 and Figure 2As shown, the support plate includes a main board 9 and two rotating plates 10 located on both sides of the main board 9. The two rotating plates 10 can only rotate towards each other, and the maximum rotation angle is 90 degrees. The cross-section of the receiving groove 4 is C-shaped. Two snap-fit ​​holes 8 are located on the two rotating plates 10 respectively. The roller body 1 is provided with four support rods 6, and one of the support plates is provided with two support rods 6. The support rods 6 are stored in the receiving groove 4 by bending, so that they can have a large contact area with the ground after subsequent unfolding, ensuring the stability of the support rods 6. In addition, the two rotating plates 10 can only rotate in the same direction, so the stability of the support plate will not be affected when the support plate is laid flat. The main board 9 and A torsion spring is provided between the rotating plates 10. When the torsion spring is in its natural state, one side of the rotating plate 10 is flush with the main plate 9. The torsion spring provides a restoring force to the rotating plate 10. This arrangement ensures that when the support plate is stored in the receiving groove 4, the rotating plate 10 will abut against the inner wall of the receiving groove 4 due to the force of the torsion spring, thereby increasing the friction between the rotating plate 10 and the inner wall of the receiving groove 4. This makes it difficult for the support plate to detach from the receiving groove 4. Rubber strips 12 are provided on both sides of the rotating plate 10. The rubber strip 12 on one side is used to increase the friction between the rotating plate 10 and the inner wall of the receiving groove 4, and the rubber strip 12 on the other side is used to increase the friction between the rotating plate 10 and the platform.

[0020] like Figure 2 As shown, a rubber ring is provided on the side of the support rod 6 facing away from the threaded post 7. The depth of the circular groove 5 is equal to the length of the support rod 6. The rubber ring increases the friction between the support rod 6 and the snap-fit ​​hole 8, and also makes it less likely for the support rod 6 to detach from the circular groove 5 under the action of the rubber ring. The threaded post 7 protrudes outside the circular groove 5, providing a point of leverage for people to remove the support rod 6. Several snap-fit ​​slots 11 are provided on the rectangular block 3, which are connected to the receiving groove 4. The snap-fit ​​slots 11 make it convenient for people to remove the support plate from the receiving groove 4.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
