Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing equipment technology, specifically a device for preventing materials from falling to the ground during the tread separation and storage process. Background Technology

[0002] In tire production, tread material needs to be rolled up by a trolley and then guided to the conveyor feeding rack. Current technology uses an active guide motor combined with a magnetic powder brake to control the rolling speed, but due to inertia, this easily leads to excessive accumulation, causing the tread to directly contact the ground, resulting in material contamination and waste. Simultaneously, issues such as material stretching and piling affect production efficiency and increase the labor intensity of employees. There is an urgent need for a simple anti-fall device to solve these problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tire tread guide storage anti-drop system, designed to effectively buffer the speed difference between preceding and following processes, prevent the tire tread from falling to the ground, reduce the floor space required, and adapt to different tire tread specifications. The system includes: a winding trolley track, adapted for the winding trolley to enter within it;

[0004] A material feeding rack, located downstream of the winding trolley track, includes a conveying track adapted to convey tire tread downstream;

[0005] An anti-fall device is placed between the winding trolley track and the material feeding frame. The anti-fall device defines a buffer chamber, which is an open U-shaped trough. The bottom of the buffer chamber is lower than the working plane height of the conveying track.

[0006] A baffle is fixed at the end of the winding trolley track. The vertical height of the baffle is greater than the depth of the buffer chamber, and its top is equipped with a freely rotatable baffle roller to contact and guide the tire tread into the buffer chamber via an inclined downward path.

[0007] In some embodiments, the anti-landing device includes multiple unpowered rollers arranged along the tire tread conveying direction, the unpowered rollers forming a U-shaped roller track, the width of the U-shaped roller track being greater than the maximum specification width of the tire tread.

[0008] In some embodiments, the anti-fall device includes:

[0009] U-shaped side panels arranged symmetrically on the left and right sides;

[0010] Multiple unpowered rollers installed between the two U-shaped side plates;

[0011] The base frame is fixedly connected to the bottom of the U-shaped side plate.

[0012] In some embodiments, the anti-fall device further includes a square steel base frame welded to the bottom of the U-shaped side plate, and a base plate fixed to the ground by expansion bolts, the base plate having mounting holes.

[0013] In some implementations, the number of unpowered rollers is sufficient to prevent the tire tread from sagging and contacting the ground even at the maximum buffer length.

[0014] In some embodiments, the height, width, and curvature of the U-shaped side plate are the same.

[0015] Another objective of this invention is to provide a tread-guided storage anti-fall device as described above.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention effectively solves the speed difference buffering problem by setting a U-shaped buffer chamber and its natural drop section between the winding and conveying processes, protecting the tire tread from tensile damage. Its open U-shaped groove design effectively prevents the tire tread from jamming due to width changes and saves space by utilizing gravity for drop. The baffle integrates guidance and safety protection. The unpowered roller structure is simple and reliable, reducing costs. The overall system effectively eliminates the risk of tire tread contamination upon impact, improving production continuity and tire tread quality. Attached Figure Description

[0021] The present invention or its technical solution will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or the internal connection between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. Please refer to... Figure 1This embodiment provides a tire tread guide storage anti-drop system. The system includes a winding trolley track 1, a material feeding rack 2, an anti-drop device 3, and a baffle 4. The winding trolley track 1 is adapted for the winding trolley to enter and unwind the tire tread roll. The material feeding rack 2 is located downstream of the winding trolley track 1 and includes a conveying track 21, which is adapted to receive and continue conveying the tire tread to the downstream process. The anti-drop device 3 is placed between the winding trolley track 1 and the material feeding rack 2. The anti-drop device 3 defines a buffer chamber, which is an open U-shaped groove. The open sidewalls of the U-shaped groove allow slight displacement of the tire tread, preventing jamming due to width changes. The bottom of the buffer chamber is lower than the working plane height of the conveying track 21. This height difference causes the tire tread, before entering the material feeding track, to naturally sag due to gravity, forming a natural sag buffer section within the U-shaped groove. The drooping tire tread forms an "S"-shaped arc storage area within the U-shaped groove. This drooping section provides a crucial buffer space for the instantaneous difference between the unwinding speed of the winding trolley and the traction speed of the conveyor. It absorbs the speed difference between the two, preventing the tire tread from being forcibly stretched, deformed, or piled up. By utilizing gravity to naturally droop and form a buffer section, rather than the traditional horizontal spreading storage method, the footprint of the device is greatly reduced. Baffle 4 is fixed at the end of the winding trolley track 1, and a freely rotatable baffle roller 41 is provided on the top of baffle 4. This baffle roller 41 is used to contact and guide the tire tread exiting from the winding trolley, allowing it to smoothly enter the U-shaped groove opening of the buffer bin along a downward inclined path. The vertical height of the baffle 4 is designed to be greater than the depth of the buffer bin. Its main purpose is to prevent the winding trolley from rushing forward excessively due to inertia or operational errors, colliding with the downstream conveyor 2 or the anti-fall device 3, thus providing physical restraint and safety protection.

[0023] In some embodiments of this utility model, the anti-fall device 3 includes multiple unpowered rollers 33 arranged along the tire tread conveying direction. The unpowered rollers 33 are arranged to form a U-shaped roller channel, the width of which is greater than the maximum specification width of the applicable tire tread. The unpowered rollers 33 slide within the U-shaped groove relying on the tension and movement of the tire tread itself, without the need for an additional drive mechanism, effectively reducing system cost and complexity.

[0024] In some embodiments, the anti-fall device 3 includes symmetrically arranged U-shaped side plates 31, multiple unpowered rollers 33 installed between the two U-shaped side plates 31, and a base frame 32 fixedly connected to the bottom of the U-shaped side plates 31. Exemplarily, the anti-fall device 3 includes a square steel base frame 32 welded to the bottom of the U-shaped side plates 31, and a base plate 34 fixed to the ground by expansion bolts, the base plate 34 having mounting holes. This structure ensures the stability of the device and ease of on-site installation.

[0025] The number of unpowered rollers 33 must meet a key requirement: even when the tire tread reaches its maximum buffer length (i.e., when the sag is deepest), the rollers must still provide sufficient support to effectively prevent the tire tread from sagging excessively and contacting the ground. To ensure structural symmetry and operational stability, the height, width, and curvature of the U-shaped side plates 31 are all designed to be the same.

[0026] Combination Figure 1 The working process of the embodiments of this utility model is further explained as follows: The winding trolley runs along the winding trolley track 1 to its position, and the tire tread is guided. The guided tire tread first contacts the free-rotating guide roller 41 at the top of the baffle 4, and moves downward at an angle under the guidance of the guide roller 41. The tire tread enters the U-shaped buffer bin opening of the anti-fall device 3; since the bottom of the trough is lower than the downstream conveying plane, the tire tread naturally droops under the action of gravity, forming an S-shaped storage area in the U-shaped trough. The tire tread is supported and guided to slide in the U-shaped trough by multiple unpowered rollers 33, and finally smoothly transitions to the conveying track 21 of the material feeding rack 2, continuing to be conveyed downstream. When the speed of the winding trolley is instantaneously faster than the conveying speed, the length of the drooping section in the buffer bin increases to absorb excess tire tread; conversely, the length of the drooping section decreases to release the tire tread, always maintaining a relatively stable tire tread tension and avoiding falling or hard stretching. The baffle 4 effectively prevents the winding trolley from rushing out of the winding trolley track 1 and hitting the downstream equipment.
