Description

Anti-clogging film take-up bridge conveyor system and its application Technical Field

[0001] This invention relates to equipment for tire semi-finished product production lines, specifically to an anti-clogging rubber roll take-up and conveying system and its application. Background Technology

[0002] In continuous production lines for semi-finished tires, the transition section between the extrusion or calendering process and the winding station is crucial. Traditional solutions typically employ a "bridge" structure consisting of modular conveyor belts and guide frames. The modular conveyor belts are responsible for carrying and transporting the tires, while the guide frames are used to alternately guide the continuous flow of semi-finished products such as treads and sidewalls to multiple winding stations (e.g., while one station is winding, another station is unloading and preparing materials), aiming to achieve continuous production.

[0003] However, the existing "modular belt + swing frame" structure poses a significant risk of rubber clogging when conveying thin, highly viscous semi-finished tires. Specifically: First, the highly viscous thin rubber material tends to accumulate at the head when the swing frame switches directions due to increased resistance on the guide surface; second, the material may seep into the seams of the modular belt and be scraped and accumulated as it passes through the gaps below the swing frame; third, the material driving force may fluctuate during the swing frame switching, causing the viscous material to sag under its own weight and adhere to stationary components.

[0004] This glue blockage problem leads to unplanned downtime, is difficult to clean, and may damage equipment and affect product quality, becoming a technical bottleneck restricting the stable and efficient operation of this process. Therefore, an optimization solution is urgently needed to improve the reliability of the conveying process. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide an anti-clogging film roll take-up and conveying system and its application.

[0006] This invention is achieved through the following technical solution:

[0007] In a first aspect, the present invention provides an anti-clogging film roll take-up and conveying system, comprising a support frame and a conveyor belt disposed on the conveying frame; the support frame includes a fixed frame and a swing frame, the fixed frame and the swing frame being rotatably connected, a drive shaft being connected to the fixed frame via a first drive mechanism, and driven rollers being provided at opposite ends of the fixed frame and the swing frame, the conveyor belt passing sequentially through the drive shaft and the driven rollers; a fixed frame is provided at one end of the fixed frame near the swing frame, and second drive mechanisms are respectively hinged to both sides of the fixed frame, the output ends of the second drive mechanisms being hinged to the swing frame.

[0008] A further improvement of the present invention is that the fixed frame includes two first side plates that are arranged opposite to each other and parallel to each other. The two first side plates include an inclined section and a horizontal section that are connected to each other. The inclined section is inclined upward from one end to the end located on the horizontal section.

[0009] A further improvement of the present invention is that: the first driving mechanism is fixed on the horizontal section of one of the first side plates, the transmission shaft is disposed between the two first side plates and is connected to the output shaft of the first driving mechanism; the conveyor belt passes through the lower surface of the transmission shaft and provides conveying power to the conveyor belt through the transmission shaft.

[0010] A further improvement of the present invention is that the swing frame includes two second side plates that are arranged opposite to each other and parallel to each other, and the two second side plates are respectively connected to the horizontal sections of the two first side plates by a rotating shaft.

[0011] A further improvement of the present invention is that: the two second side plates are respectively located inside the two first side plates, and a bearing seat is provided between the second side plates and the first side plates, and the two ends of the rotating shaft pass through the second side plate, the bearing seat and the first side plate in sequence.

[0012] A further improvement of the present invention is that: the fixing frame includes two upright plates respectively fixed to the horizontal section of the first side plate, a horizontal plate is fixedly connected between the top ends of the two upright plates, and the two ends of the horizontal plate are respectively hinged to the second driving mechanism, and the output shaft of the second driving mechanism is respectively hinged to the two second side plates.

[0013] A further improvement of the present invention is that: a first idler roller, a second idler roller, and a third idler roller are provided between the horizontal sections of the two first side plates, the first idler roller is located between the inclined section of the first side plate and the drive shaft, the second idler roller and the third idler roller are located between the drive shaft and the swing frame, and the first idler roller, the second idler roller, and the third idler roller are all located above the drive shaft; the conveyor belt passes sequentially through the driven roller on the swing frame, the upper surfaces of the third idler roller and the second idler roller, the lower surface of the drive shaft, the upper surface of the first idler roller, and the driven roller on the fixed frame.

[0014] A further improvement of the present invention is that a tensioning mechanism is provided between the inclined sections of the two first side plates.

[0015] A further improvement of the present invention is that: the tensioning mechanism includes a first guide roller and a second guide roller fixed between two first side plates, and a tension swing roller is provided between the first guide roller and the second guide roller; the conveyor belt passes sequentially through the driven roller on the swing frame, the upper surface of the third idler roller and the second idler roller, the lower surface of the drive shaft, the upper surface of the first idler roller, the upper surface of the second guide roller, the lower surface of the tension swing roller, the upper surface of the first guide roller, and the driven roller on the fixed frame.

[0016] In a second aspect of the present invention, the anti-clogging rubber roll take-up bridge conveying system is applied in a tire semi-finished product production line.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: The anti-clogging rubber roll take-up and bridging conveyor system of this invention adopts a "one-piece conveyor belt loop" design, meaning that the same seamless modular conveyor belt simultaneously constitutes both the fixed and swing parts of the bridging conveyor system, completely eliminating the traditional independently driven roller or drum structure at the end of the swing frame. This design physically avoids the possibility of viscous rubber being squeezed and accumulated at the meshing point between the conveyor belt and the independent roller, thus eradicating the root cause of blockage caused by "rubber clamping." The smooth and continuous transition of the conveyor belt at the hinge point of the swing frame ensures smooth, resistance-free, and unobstructed turning and guidance, even for highly viscous, thin tire sidewall rubber, guaranteeing uninterrupted continuous operation of the production line.

[0018] To accelerate the response speed of the swing frame, this invention places the main motor driving the conveyor belt on the horizontal section of the fixed frame, rather than mounting it on the swing frame itself. This significantly reduces the moment of inertia of the swing frame, making its lifting and lowering movements under cylinder drive faster and smoother. Faster switching speeds mean a significantly shorter transition time for material flow from the current station to the preparatory station, reducing the risk of sticky materials sticking and accumulating due to gravity or power interruption caused by prolonged switching processes. Simultaneously, the lightweight swing frame moves more smoothly and positions more accurately, further improving the reliability of guidance.

[0019] To address the potential issues of slight elongation and uneven stress distribution in different sections of the conveyor belt, this invention incorporates a tensioning mechanism between the inclined sections of the two first side plates. This mechanism provides real-time compensation for length variations caused by long-term operation or temperature changes, maintaining a constant and appropriate tension throughout the entire conveying path (including the swing path passing through the swing frame). Constant tension is crucial for conveying thin and soft semi-finished tires: it prevents belt loosening that could lead to material slippage or misalignment, and also avoids excessive tension that could cause overstretching or deformation of the thin rubber material. This ensures that the material maintains its preset size and shape during high-speed, continuous conveying, improving product consistency.

[0020] The integrated design of this invention brings about a significant simplification in structure. Replacing the original combination of multi-segment belts and independent rollers with a single closed-loop conveyor belt reduces the number of parts, and in particular eliminates high-risk points for failure such as roller bearings and separate drive units. This structural simplification directly translates into higher system reliability and reduces unexpected downtime caused by complex mechanical failures. At the same time, maintenance becomes much simpler: only one conveyor belt and its core drive tensioning mechanism need to be maintained, greatly reducing the workload and cost of daily inspection, lubrication, and replacement of parts.

[0021] Through the aforementioned structural innovations, this invention not only specifically addresses the bottleneck of "glue blockage" in the manufacturing process, but also achieves synergistic optimization in multiple aspects, including production efficiency (faster switching speed, reduced downtime), product quality (stable tension, maintained shape), equipment reliability (simplified structure, reduced failure rate), and operating and maintenance costs (easy maintenance, reduced wear). This system is particularly suitable for modern intelligent tire manufacturing scenarios with extremely high requirements for conveying stability, providing key technological equipment support for the efficient and clean production of high-quality tire semi-finished products.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings: As shown in Figures 1 and 2, an embodiment of the present invention provides an anti-clogging rubber roll pick-up and conveyor system, including a support frame and a conveyor belt 1 disposed on the support frame; the support frame includes a fixed frame and a swing frame, the fixed frame is fixed to the ground by a support frame, the fixed frame and the swing frame are rotatably connected, a drive shaft 4 is connected to the fixed frame by a first drive mechanism 2, and driven rollers 3 are provided at opposite ends of the fixed frame and the swing frame, the conveyor belt 1 passes through the drive shaft 4 and the driven rollers 3 in sequence to be disposed on the support frame; a fixed frame 5 is provided at one end of the fixed frame near the swing frame, and a second drive mechanism 6 is hinged to both sides of the fixed frame 5, the output end of the second drive mechanism 6 is hinged to the swing frame, and the swing frame and its corresponding conveyor belt are lifted / lowered under the drive of the second drive mechanism 6 to realize the conveying of tire semi-finished products to different workstations.

[0025] This invention employs a "single-segment conveyor belt" design, where a single, seamless modular conveyor belt forms both the fixed and oscillating sections of the bridge conveyor system, completely eliminating the need for independently driven rollers or drums at the end of the traditional swing frame. This design physically prevents the possibility of viscous rubber being squeezed and accumulated at the meshing point between the conveyor belt and the independent rollers, thus eradicating the root cause of blockages caused by "rubber trapping." The smooth and continuous transition of the conveyor belt at the swing frame hinge point ensures smooth, resistance-free, and unobstructed steering and guidance, even for highly viscous, thin tire sidewall rubber, guaranteeing uninterrupted continuous operation of the production line.

[0026] To accelerate the response speed of the swing frame, this invention mounts the drive mechanism on a fixed frame instead of the swing frame, significantly reducing the moment of inertia of the swing frame. This makes the lifting and lowering of the swing frame under cylinder drive faster and smoother. Faster switching speed means a significantly shorter transition time for material flow from the current station to the preparatory station, reducing the risk of sticky materials sticking and accumulating due to gravity or power interruption caused by prolonged switching processes. Simultaneously, the lightweight swing frame moves more smoothly and is positioned more accurately, further improving the reliability of guidance.

[0027] In a preferred embodiment of the present invention, the fixed frame includes two first side plates 7 arranged opposite to each other and parallel to each other. Each first side plate 7 includes a connected inclined section and a horizontal section. The inclined section is inclined upwards from one end to the end located on the horizontal section. The first drive mechanism 2 is fixed to the horizontal section of one of the first side plates 7 by a fixed seat. The drive shaft 4 is disposed between the two first side plates 7 and is drively connected to the output shaft of the first drive mechanism 2. The conveyor belt 1 passes through the lower surface of the drive shaft 4, and the drive shaft 4 provides conveying power to the conveyor belt 1. Preferably, the first drive mechanism 2 is a motor. More preferably, both ends of the drive shaft 4 are fixed to the horizontal sections of the two first side plates 1 by bearing seats, and one end of the drive shaft 4 passes through the first side plate and is connected to the output shaft of the first drive mechanism 2 by a coupling.

[0028] In a preferred embodiment of the present invention, the swing frame includes two parallel second side plates 8 arranged opposite to each other. The two second side plates 8 are respectively connected to the horizontal sections of the two first side plates 7 via a rotating shaft. Preferably, the two second side plates 8 are located inside the two first side plates 7, and a bearing seat is provided between the second side plates 8 and the first side plates 7. The two ends of the rotating shaft pass through the second side plates 8, the bearing seat, and the first side plates 7 in sequence. When the second drive mechanism 6 drives the swing frame to perform a lifting / lowering action, the swing frame can move upward or downward around the rotating shaft. Preferably, the first side plates 7 and the second side plates 8 are provided with threaded holes at positions corresponding to the drive shaft. The rotating shaft is threadedly connected to the first side plates and the second side plates, respectively, and the drive shaft is fixedly connected to the inner wall of the bearing seat.

[0029] In a preferred embodiment of the present invention, the fixing frame includes two vertical plates respectively fixed to the horizontal section of the first side plate 7. A horizontal plate is fixedly connected between the top ends of the two vertical plates. The two ends of the horizontal plate are respectively hinged to the second driving mechanism 6. The output shaft of the second driving mechanism 6 is respectively hinged to the two second side plates 8, so that the two second side plates 8 can be lifted / lowered under the drive of the second driving mechanism 6, thereby driving the corresponding part of the conveyor belt to be lifted / lowered, so as to realize the transportation of the semi-finished tire to different workstations. Preferably, the second driving mechanism 6 is a cylinder.

[0030] In a preferred embodiment of the present invention, a first idler roller 9, a second idler roller 10, and a third idler roller 11 are provided between the horizontal sections of the two first side plates 7. The first idler roller 9 is located between the inclined section of the first side plate 7 and the drive shaft 4. The second idler roller 10 and the third idler roller 11 are located between the drive shaft 4 and the swing frame. The first idler roller 9, the second idler roller 10, and the third idler roller 11 are all located above the drive shaft 4. The conveyor belt 1 passes sequentially through the driven roller 3 on the swing frame, the upper surface of the third idler roller 11 and the second idler roller 10, the lower surface of the drive shaft 4, the upper surface of the first idler roller 9, and the driven roller 3 on the fixed frame. Under the action of the first drive mechanism 2, the conveyor belt 1 is provided with conveying power through the drive shaft 4.

[0031] In a preferred embodiment of the present invention, to address the potential issues of slight elongation and uneven stress distribution in different sections of the conveyor belt, a tensioning mechanism is provided between the inclined sections of the two first side plates 7. This tensioning mechanism can compensate in real time for length changes in the conveyor belt caused by long-term operation or temperature variations, and maintain a constant and appropriate tension throughout the entire conveying path (including the swing path through the swing frame) to ensure smooth conveying. The tensioning mechanism is located inside the conveyor belt 1 and includes a first guide roller 12 and a second guide roller 13 fixed between the two first side plates 7. A tension swing roller 14 is provided between the first guide roller 12 and the second guide roller 13. The conveyor belt 1 sequentially passes through the driven roller 3 on the swing frame, the upper surfaces of the third idler roller 11 and the second idler roller 10, the lower surface of the drive shaft 4, the upper surface of the first idler roller 9, the upper surface of the second guide roller 13, the lower surface of the tension swing roller 14, the upper surface of the first guide roller 12, and the driven roller 3 on the fixed frame. Preferably, the two ends of the tension swing roller are connected to the two first side plates by swing arms. Specifically, one end of the swing arm is rotatably connected to the connecting shaft of the first side plate, and the other end is fixedly connected to the roller shaft of the tension swing roller. The tension swing roller swings freely under the action of the swing arm and achieves the tensioning action of the conveyor belt by its own gravity to ensure smooth conveying.

[0032] When using the anti-clogging rubber roll pick-up and conveyor system of this invention to transport thin, highly viscous tire semi-finished products from one workstation to another, the swing frame is driven by a second drive mechanism (cylinder) to lift or lower until it is level with the workstation it is connected to. The first drive mechanism (motor) then provides conveying power to the conveyor belt, which transports the thin, highly viscous tire semi-finished products from one workstation to another, achieving continuous production. Because this invention adopts a "one-piece conveyor belt loop" design, that is, using the same seamless modular conveyor belt to simultaneously form the fixed and swing parts of the bridge conveyor system, it completely eliminates the traditional independently driven roller or drum structure at the end of the swing frame. This design physically avoids the possibility of viscous rubber being squeezed and accumulated at the meshing point between the conveyor belt and the independent roller, thus eradicating the root cause of blockage caused by "rubber trapping". The smooth and continuous transition of the conveyor belt at the hinge point of the swing frame ensures smooth and unobstructed turning and guidance, even for thin tire sidewall rubber with high viscosity, guaranteeing uninterrupted continuous operation of the production line.
