Description

Technical Field

[0001] This utility model relates to the technical field of silent cotton bonding devices, specifically to a spring roll device for a silent cotton bonding machine. Background Technology

[0002] Tires are the automotive components that come into direct contact with the ground. To reduce the noise generated by tires during driving, quiet tires have become a new consumer demand. One technology for reducing tire noise is to apply sound-absorbing foam to the inside of the tire. In this technology, the quality of the sound-absorbing foam application directly affects the tire's noise reduction performance. Traditional sound-absorbing foam application equipment generally includes a machine table, a spool on the machine table for winding the sound-absorbing foam, a cutting mechanism for cutting the sound-absorbing foam, and a bonding mechanism for applying the sound-absorbing foam. However, before applying the sound-absorbing foam, the PE paper on the adhesive side of the sound-absorbing foam needs to be peeled off. Therefore, a device is needed to clamp the PE paper of the sound-absorbing foam in conjunction with the sound-absorbing foam application machine. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background art and provide a spring roll device for a silent cotton bonding machine.

[0027] Example 1, see Figure 1-2 :

[0028] A spring coil device for a silent cotton laminating machine includes a drive unit connected to a main shaft 1. The main shaft 1 rotates under the action of the drive unit. The front section of the main shaft 1 is provided with a working surface for placing silent cotton PE paper. A clamping plate 2 is arranged above the working surface. The clamping plate 2 is rotatably mounted on the main shaft 1 via a rotating component. The main shaft 1 is recessed with a mounting part 6 corresponding to the rotating component. The clamping plate 2 is provided with a mating surface corresponding to the working surface. The mating surface of the clamping plate 2 is used to mate with the working surface 10 to clamp the silent cotton PE paper. In use, the clamping plate 2 is rotated so that the mating surface presses against the working surface 10, thereby clamping the silent cotton PE paper.

[0029] A torsion spring 3 is also installed in the mounting part 6 below the clamping plate 2. The torsion spring 3 is used to assist the clamping plate 2 in clamping the sound-absorbing PE paper. When the clamping plate 2 is closed, the torsion spring 3 converts the stored deformation energy into kinetic energy. The clamping plate 2 rotates and presses down along the closing direction, which helps to increase the closing force of the clamping plate 2 and increase the clamping effect on the sound-absorbing PE paper.

[0030] In one implementation, the driving device employs a pneumatic motor. It is understood that the sound-absorbing cotton comes in various specifications, such as thicknesses of 1mm, 2mm, and 3mm, with different thicknesses and widths selected according to actual needs. Preferably, the length of the mating surface is not less than the required width of the sound-absorbing cotton.

[0031] In one embodiment, the mating surface is provided with toothed protrusions 20, which facilitates the clamping plate 2 to better clamp the sound-absorbing PE paper.

[0032] In one embodiment, the protrusions 20 are arranged in two rows on both sides of the mating surface.

[0033] In one embodiment, the size of the protrusion 20 located on the side away from the rotating member is larger than the size of the protrusion 20 on the other side.

[0034] In one embodiment, magnet blocks 4 are correspondingly provided on the clamping plate 2 and the working surface 10. When the mating surface and the working surface 10 are used to clamp the sound-absorbing PE paper, the magnetic attraction of the magnet blocks 4 on both sides helps to increase the clamping effect of the sound-absorbing PE paper.

[0035] In one embodiment, the rotating component is located behind the working surface 10, and the clamping plate 2 and the corresponding magnet block 4 on the working surface 10 are arranged on the side away from the rotating component.

[0036] In one embodiment, the rotating component includes an elastic cylindrical pin 5, and the clamping plate 2 is rotatably mounted on the mounting part 6 via the elastic cylindrical pin 5.

[0037] In one embodiment, the clamping plate 2 includes a working plate portion 22, the inner side of the working plate portion 22 is a mating surface, and the rear end of the working plate portion 22 is provided with an inclined portion corresponding to the rotation arm 31 of the torsion spring 3. Rotating portions 21 are provided on both sides of the inclined portion, and the rotating portions 21 are provided with a first pin hole for installing the elastic cylindrical pin 5.

[0038] It is understood that the torsion spring 3 has a spring body 30 and two rotating arms 31. Through the rotating arms 31 rotating around the central axis of the spring body 30, the spring body 30 can store and release energy. One rotating arm 31 of the torsion spring 3 is fixed to the mounting part 6, and the other rotating arm 31 abuts against or is connected to the inclined part. The mounting part 6 has a first space for mounting the torsion spring 3 and rotating the rotating arms 31. The mounting walls 60 on both sides of the first space are used to install the elastic cylindrical pin 5 and the second pin hole on it. The second pin hole is directly opposite the first pin hole. The elastic cylindrical pin 5 passes through the spring body 30, and the rotation center of the rotating arm 31 is located on the axis of the second pin hole.

[0039] In one embodiment, the length of the spring body 30 is less than the distance between the inner sidewalls of the two mounting walls 60, the spring body 30 is arranged between the two mounting walls 60, and the distance between the outer sidewalls of the two mounting walls 60 is less than the distance between the inner sidewalls of the two rotating parts 21, which facilitates the installation of the clamping plate 2.

[0040] In one implementation, the drive device is communicatively connected to the silent cotton laminating machine via a control device on-site in the workshop.

[0041] The working principle of this embodiment:

[0042] In use, the clamping plate 2 is opened, and the operator places the PE paper of the sound-absorbing cotton, peeled off from the end, onto the working surface 10. Under the action of the torsion spring 3, the clamping plate 2, in conjunction with the working surface 10, clamps the PE paper. The toothed protrusions 20 and the magnet help improve the clamping effect. As the sound-absorbing cotton laminating machine works, the sound-absorbing cotton is adhered to the tire. The peeled PE paper is wound around the outside of the main shaft 1 as the main shaft 1 rotates. After the PE paper is wound, the clamping plate 2 is rotated upwards to open and the wound PE paper is removed. It is understood that in practical applications, the winding speed of the PE paper on the main shaft 1 is synchronized with the laminating speed of the sound-absorbing cotton laminating machine.

[0043] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
