Description

Technical Field

[0001] The invention belongs to the field of all-steel radial tire production, and in particular relates to a device for preventing tail materials from falling to the ground during a conveying process. Background Art

[0002] With the advancement of intelligent manufacturing, all-steel radial tire building machines are becoming increasingly automated. They are now producing rolls of semi-finished components, rather than single strips. These rolls are transported along the machine's conveyor belt and automatically cut to pre-set lengths. However, the tail of the roll, lacking support, can fall off at the junction of the conveyor belts, causing the semi-finished components to fall to the ground and become contaminated. This contaminated part, if used in a tire, can severely affect component adhesion and lead to premature tire failure. Furthermore, the falling part can cause excessive localized stretching and deformation of the rubber component, impacting the distribution of tire material and, consequently, the quality of the finished tire. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for preventing tail materials from falling to the ground during the transmission process, so as to solve the problem that in the production process of all-steel radial tires, the rubber parts that need to be transported may fall at the end, causing the parts to become dirty or locally stretched too much, seriously affecting the quality of the parts fitting, and causing early damage to the tire products.

[0004] The present invention is achieved in this way:

[0005] A device for preventing tailings from falling to the ground during conveying, the device comprising:

[0006] A passive shaft is arranged at the tail end of the conveyor belt, and the passive shaft rotates synchronously driven by the active shaft of the transmission system; a receiving plate is sleeved on the passive shaft, and the rubber material is pressed on one side of the receiving plate during operation, and a plurality of counterweights are arranged at the same distance from the edge of the receiving plate. When the rubber material separates from the passive shaft, the counterweight drives the other side of the receiving plate to tilt downward and connect with the conveyor belt that receives the falling rubber material.

[0007] Furthermore, a bracket with two surfaces is provided below the receiving plate, and one side surface of the bracket supports a counterweight. By adjusting the height of the top of the bracket, the maximum inclination angle of the receiving plate is controlled.

[0008] Furthermore, one side of the receiving plate is a pressed plate, which adopts an arc-shaped structure and is sleeved on the passive shaft without fitting the passive shaft.

[0009] Furthermore, a plurality of hollow structures are provided on one side of the receiving plate where the pressed plate is provided, and the hollow structures are provided on the receiving plate close to the pressed plate, and part of the passive shaft contacts the rubber material through the hollow structures.

[0010] Furthermore, a plurality of cams with equal spacing are provided on the passive shaft, the number of the cams matches the number of the hollow structure, and the cams protrude from the outside of the hollow structure to contact the rubber material.

[0011] Furthermore, the counterweight hammer is connected to a rotating wheel through a counterweight rope, the rotating wheel passes through a rotating shaft, both ends of the rotating shaft are fixed to a counterweight rod through a counterweight rod, and one end of the counterweight rod is fixed to the receiving plate.

[0012] Furthermore, a ball is embedded in the surface of the pressed plate that contacts the rubber material.

[0013] Furthermore, balls are embedded in the surface of the receiving plate that contacts the rubber material.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention provides a receiving plate at the tail of the rubber component that needs to be transported during the production process of the all-steel radial tire. When the tail material falls, it is automatically caught and connected to the transportation line of the next process. It prevents the problem of falling, causing the component to become dirty or locally stretched too much, seriously affecting the quality of component bonding, and causing early damage to the tire product.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] See also Figure 1 Combine Figure 2 As shown, a device for preventing tail materials from falling to the ground during transportation is used to be installed at the tail of the conveyor belt of the molding machine. A passive shaft 3 is set at the tail of the conveyor belt, and the passive shaft 3 rotates synchronously under the drive of the active shaft of the conveying system; a receiving plate 5 is sleeved on the passive shaft 3, and the receiving plate and the passive shaft have a contact part as a fulcrum. When the long rubber material 1 is running, the receiving plate and the conveyor belt are in a parallel state, and the rubber material is pressed on both sides of the contact point. After the rubber material passes through the receiving plate, it is conveyed to the conveyor belt of the subsequent process behind the receiving plate. After the continuous rubber material continues to move forward, it reaches the tail of the rubber material.

[0021] A plurality of counterweights 4 are arranged at the same distance from the edge of the receiving plate. When the rubber material separates from the passive shaft and the tail of the rubber material passes over the contact part, there is no rubber material exerting pressure on the side of the receiving plate without the rubber material. By installing a plurality of counterweights and adjusting the number and weight of the counterweights, the counterweights can drive one side of the receiving plate to tilt downward, so that the tail material will fall on the receiving plate and fall through the receiving plate onto the conveyor belt that receives the falling rubber material.

[0022] A bracket with two sides is set on the lower side of the receiving plate. One side of the bracket supports the counterweight hammer, so that the counterweight hammer can slide down along the side of the bracket, adjust the top height of the bracket, control the maximum tilt angle of the receiving plate, and avoid excessive tilt of the receiving plate.

[0023] One side of the receiving plate is the pressed plate 2, which adopts an arc structure and is sleeved on the passive shaft but does not fit the passive shaft. The contact part between the passive shaft and the receiving plate is not on the pressed plate, but is set to a curved structure to avoid scratching the rubber when the rubber is running, and to prevent the receiving plate from being disconnected from the passive shaft when tilted.

[0024] See also Figure 3 At least one hollow knot 9 is provided on one side of the receiving plate where the pressed plate is located. The hollow structure is provided on the receiving plate near the pressed plate. Part of the passive shaft contacts the rubber material through the hollow structure, allowing the rubber material to slide against the passive shaft during operation. In one embodiment, a plurality of cams can be provided on the passive shaft at equal intervals. The cams are sleeved on the passive shaft, with the number of cams matching the number of hollow structures. The hollow structure ensures that the height is consistent with that of the receiving plate, facilitating the forward movement of the rubber material.

[0025] In this embodiment, the counterweight hammer is connected to a rotating wheel 8 through a counterweight rope, the rotating wheel passes through a rotating shaft 7, both ends of the rotating shaft are fixed to a counterweight rod through a counterweight rod 6, and one end of the counterweight rod is fixed to the receiving plate.

[0026] During normal production, the adhesive parts are pressed against the pressed plate, so the receiving plate does not tilt downward. During the final production, the adhesive material moves forward along the conveyor belt, resulting in no adhesive parts on the pressed plate. The receiving plate will automatically tilt upward under the drive of the counterweight rod and counterweight hammer.

[0027] At the same time, the counterweight rod can be adjusted in angle according to the height of the front conveyor belt, thereby adjusting the angle of the receiving plate to facilitate connection with the front conveyor belt.

[0028] The weight of the hammer can be adjusted according to the weight of the rubber parts so that it does not lift too high and affect the normal operation of the rubber parts.

[0029] The pressed plate is designed with a curved structure. On the one hand, considering the friction between the pressed plate and the rubber parts during transportation, balls are embedded on the surface. At the same time, the end is designed with a curvature, so that when it is supported, its height does not exceed that of the passive wheel.

[0030] Considering that the receiving plate will produce friction with the rubber parts during transportation, balls are embedded on the surface.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
