Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a reel used for quickly clamping and peeling off double-sided adhesive sponge anti-sticking paper. Background Art

[0002] In order to improve the NVH performance of tires and improve the cavity resonance sound of tires, experiments have shown that sticking polyurethane sponge inside the tire can greatly improve the cavity resonance sound of the tire. The main production process is to use a double-sided tape-shaped polyurethane sponge with a film on one side to stick it on the inner surface of the tread along the rotating tire in the circumferential direction.

[0003] Since there is a release paper on the sponge, when using the equipment to semi-automatically stick the sponge in the tire, it is necessary to quickly clamp and simultaneously peel off the release paper on the sponge.

[0004] The traditional reel for clamping and peeling sponge release paper is designed as follows: a gap with a width of 1 to 2 mm and an effective length of about 1.2 times the width of the release paper is processed at the midline of the longitudinal axis section. During production, the end of the release paper is manually inserted into the reel slit, and after the release paper is wrapped around the reel once, the friction between the surface of the release paper and the contact surface of the shaft is used to rotate and collect. However, in practice, there are the following problems:

[0005] 1. The release paper needs to pass through the slit and wrap around the reel once, which cannot meet the actual demand of quickly clamping the release paper;

[0006] 2. The connection between the anti-sticking paper and the shaft is unreliable and easy to slip and separate, making industrial production impossible.

[0007] It can be seen that it is very important to study a reel that can quickly clamp and peel off the double-sided adhesive sponge release paper. Utility Model Content

[0008] In order to solve the above technical problems, the utility model provides a reel for quickly clamping and peeling off double-sided adhesive sponge anti-adhesive paper, including a reel body, the reel body comprising:

[0009] The clamping part is divided into two half shafts along the axis of the scroll body, and the two half shafts are rotatably fixedly connected; the two half shafts are respectively embedded with opposite magnets that attract each other; and

[0010] The self-locking component is located at the end of the clamping part and is used to close the clamping part into a cylindrical shape.

[0011] Furthermore, the self-locking component includes a buckle 2, a pin 3 and a hook, wherein the buckle 2 is arranged on the pin 3 and can rotate around the pin 3, a torsion spring 6 is arranged on the pin 3, and the buckle 2 and the hook are respectively arranged on the planes of the two half-axes, and when the clamping part is closed, the buckle 2 is engaged and connected with the hook.

[0012] Furthermore, the cross section of the buckle 2 is a "C"-shaped structure, and the hook is a "I"-shaped structure protruding along the radial direction of the semi-axis.

[0013] Furthermore, the pin shaft 3 is installed on a pin shaft seat, and the pin shaft seat is arranged to protrude radially along the half shaft.

[0014] Furthermore, a spring hinge is arranged between the two half-axles.

[0015] Furthermore, the clamping portion and the self-locking component are coaxially and integrally formed.

[0016] Furthermore, the circumferential outer surface of the clamping portion is provided with a knurled structure.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model provides a half-open clamping part and a self-locking component, so that the anti-sticking paper and the clamping part are reliably connected and not easy to separate. At the same time, the tail of the reel body is connected with the transmission device of the sponge sticking equipment, and the double-sided adhesive sponge anti-sticking paper can be quickly clamped and peeled off while the reel body rotates, thereby improving production efficiency.

[0027] In order to make the technical scheme and technical effect of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0028] Example

[0029] like Figure 1 As shown, the utility model provides a reel for quickly clamping and peeling off double-sided adhesive sponge release paper, including a rotatable reel body 100, which mainly includes a coaxial, identical-diameter, integrally formed clamping portion 110 and a self-locking assembly 120.

[0030] The clamping portion 110 can be divided into two half shafts 111 and 112 along the axis of the reel body 100. Figure 3-4 As shown, the two half shafts 111, 112 are rotatably fixedly connected along the axis of the scroll body 100. Preferably, a spring hinge 113 is provided between the two half shafts 111, 112. In order to allow the two half shafts 111, 112 to quickly close into a cylinder, opposite magnets N and S that attract each other are embedded in the cross-section of the two half shafts 111, 112. The circumferential outer surface of the clamping part 110 is provided with a knurled structure to increase the friction with the sponge release paper.

[0031] Generally, before processing and manufacturing, the two half shafts 111, 112 should be an integral bar material, and the two half shafts 111, 112 are partially symmetrically separated by wire cutting; one end of the half shaft 112 is connected to an external transmission device to realize the rotating movement of the reel.

[0032] like Figure 2 As shown, the self-locking assembly 120 is located at the axial end of the clamping part 110, and the main function of the self-locking assembly 120 is to close the clamping part 110 and form a cylindrical shape. Specifically, the lock assembly 120 includes a buckle 121, a pin 122 and a hook 124, wherein the buckle 121 is arranged on the pin 122 and can rotate around the pin 122, and a torsion spring 125 is arranged on the pin 122. The buckle 121 and the hook 124 are respectively arranged on the planes of the two half shafts 111 and 112. When the clamping part 110 is closed, the buckle 121 is engaged with the hook 124. Preferably, the cross section of the buckle 121 is a "C"-shaped structure, and the hook 124 is a "I"-shaped structure protruding radially along the half shaft 112. The pin 122 is installed on the pin seat 126, and the pin seat 126 is arranged to protrude radially along the half shaft 111.

[0033] like Figure 5-7, which shows a state cross-sectional view of the self-locking assembly 120. When the self-locking assembly 120 is in the closed state, the buckle 121 and the hook 124 are engaged and fixed; when the self-locking assembly 120 is unhooked, the torsion spring 125 is compressed, and the buckle 121 falls off the hook 124; when the self-locking assembly 120 is in the open state, the maximum angle between the two half-axes 111 and 112 where the buckle 121 and the hook 124 are respectively located is 60°.

[0034] During operation, the self-locking component 120 is in a separated state, that is, the two half-axes 111, 112 are separated in half along the axis of the reel body 100 to clamp the double-sided adhesive sponge anti-sticking paper; then the self-locking component 120 is closed, that is, the two half-axes 111, 112 are closed, and the reel body 100 rotates in a cylindrical shape; the tail of the reel body 100 is assembled with the transmission device (pneumatic motor, torque motor, servo motor, etc.) of the sponge sticking equipment to quickly peel off the double-sided adhesive sponge anti-sticking paper.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
