Description

Technical Field

[0001] This utility model relates to the technical field of conveyor belt processing equipment, and in particular to a pressure setting machine for processing wear-resistant fabric core conveyor belts. Background Technology

[0002] As a core component of material conveying widely used in modern industry, the manufacturing quality of wear-resistant fabric core conveyor belts directly affects the operational stability and service life of the entire conveying system. In the conveyor belt production process, pressure vulcanization is a crucial step. By applying precise pressure and temperature, it tightly bonds the multi-layered fabric core with materials such as rubber and completes the vulcanization reaction, thereby giving the conveyor belt the required strength, wear resistance, and elasticity.

[0003] In current processing practices, pressure forming machines are commonly used to press semi-finished conveyor belts. These machines mostly use hydraulic cylinders to directly drive the pressure plate downwards, applying pressure to the conveyor belt placed within the mold. However, this direct, rigid pressing method has inherent drawbacks: the hydraulic system is prone to generating significant impact forces during startup and pressure application, potentially damaging the equipment itself; more importantly, the pressure from a single hydraulic cylinder is difficult to distribute evenly across the entire surface of the conveyor belt, especially for large conveyor belts, where the pressure difference between the center and edge areas of the pressure plate becomes more pronounced.

[0004] This uneven pressure can lead to insufficient compaction or excessive compression in local areas of the finished conveyor belt, which in turn affects the density of its internal structure and the consistency of its physical properties. Ultimately, this may result in quality problems such as uneven product thickness, early delamination, or decreased wear resistance, making it unable to meet the requirements for high-performance conveyor belts.

[0005] Furthermore, after the pressure setting process is completed, the formed conveyor belt is often difficult to remove from the mold due to its tight fit with the mold frame. Traditional removal methods mostly rely on manual prying with tools or direct removal by hand, which is not only cumbersome and labor-intensive, but also prone to scratching or deforming the freshly shaped and still warm conveyor belt during the removal process, affecting the product's appearance and pass rate, and reducing overall production efficiency.

[0006] Therefore, this utility model proposes a pressure setting machine for processing wear-resistant fabric core conveyor belts to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a pressure setting machine for processing wear-resistant fabric core conveyor belts, aiming to improve the problems of large impact force during the pressure process, uneven pressure distribution, and inconvenient operation for removing finished products in the existing pressure setting machine for processing wear-resistant fabric core conveyor belts.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a pressure setting machine for processing wear-resistant fabric core conveyor belts, comprising: Processing table; A support frame is fixedly connected to the top of the processing table; The hydraulic cylinder is mounted on the support frame; The model frame is placed on the processing table; It also includes: a first pressure plate, which is movably connected to the end of the piston rod of the hydraulic cylinder; The second pressure plate is located below the first pressure plate, and the first pressure plate and the second pressure plate are slidably connected by a sliding column; A first spring is disposed between the first pressure plate and the second pressure plate; A lifting plate, which is movably disposed at the bottom inside the model frame; A connecting rod, one end of which is fixedly connected to the lifting plate, and the other end of which passes through a limiting groove opened in the side wall of the model frame; The handle is fixedly connected to the end of the connecting rod located outside the limiting groove via a connecting plate.

[0009] Preferably, it also includes a controller, which is mounted on the support frame and electrically connected to the hydraulic cylinder.

[0010] Preferably, the first spring surrounds the outside of the sliding post.

[0011] Preferably, the pressure setting machine for processing wear-resistant fabric core conveyor belts further includes a molding plate, which is detachably connected to the bottom of the second pressure plate.

[0012] As a specific connection method, a pin plate is fixed to the top of the molding plate, and a fixing frame that is inserted and engaged with the pin plate is fixed to the bottom of the second pressure plate.

[0013] Furthermore, a pull rod is slidably disposed inside the pin plate, and a positioning post for locking is fixedly connected to the pull rod.

[0014] Preferably, a second spring is also sleeved on the pull rod, and the second spring abuts against the inner wall of the positioning post and the pin plate.

[0015] To achieve locking, the fixing frame has a positioning hole through which the positioning post passes.

[0016] Preferably, a sliding plate is fixedly connected to the end of the pull rod away from the positioning post, and the sliding plate is slidably disposed inside the fixed frame.

It enables the disassembly and assembly of the molding plate to be completed by hand and quickly, which significantly simplifies the equipment maintenance and cleaning process and reduces downtime.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 This utility model provides a pressure setting machine for processing wear-resistant fabric core conveyor belts, which aims to solve the problems of large pressure impact, uneven pressure distribution, and inconvenient product removal in existing conveyor belt pressure equipment.

[0022] Specifically, it includes a processing table 1 and a support frame 2 fixedly connected above the processing table 1. The processing table 1 is used to provide a mounting base for the entire device, while the support frame 2 is used to support the pressurizing mechanism. The hydraulic cylinder 201 is mounted on the support frame 2, and the model frame 4 is placed on the processing table 1.

[0023] It also includes an elastic buffer pressure assembly consisting of a first pressure plate 202, a second pressure plate 203, a sliding column 204 and a first spring 205, and a finished product ejection mechanism consisting of a lifting plate 401, a connecting rod 402, a limiting groove 403, a connecting plate 404 and a handle 405.

[0024] The first pressure plate 202 is movably connected to the piston rod end of the hydraulic cylinder 201 to receive and transmit the initial pressure from the hydraulic cylinder 201. The second pressure plate 203 is located below the first pressure plate 202. The first pressure plate 202 and the second pressure plate 203 are slidably connected by a sliding column 204. The sliding column 204 provides guidance for the relative movement of the two pressure plates. The first spring 205 is disposed between the first pressure plate 202 and the second pressure plate 203. This structure ensures that the downward pressure of the hydraulic cylinder 201 does not act directly and rigidly on the material, but is buffered and redistributed through the first spring 205, thus ensuring the smooth application and uniform distribution of pressure.

[0025] Please refer to the following carefully. Figure 5 and Figure 6 The finished product ejection mechanism is described in detail below: The lifting plate 401 is movably set at the bottom of the inside of the model frame 4, serving as a platform to support and lift the finished product. One end of the connecting rod 402 is fixedly connected to the lifting plate 401, and the other end of the connecting rod 402 passes through the limiting groove 403 opened on the side wall of the model frame 4. The limiting groove 403 provides guidance and constraint for the movement trajectory of the connecting rod 402. The handle 405 is fixedly connected to the end of the connecting rod 402 located outside the limiting groove 403 through the connecting plate 404. By pulling the handle 405, the entire mechanism can be driven to move and eject the processed conveyor belt from the model frame 4.

[0026] It also includes a controller 3, which is installed in a prominent and easily accessible position on the support frame 2. The controller 3 is electrically connected to the hydraulic cylinder 201. The operator can set process parameters such as pressurization time and pressure through the controller 3. The controller 3 precisely controls the action of the hydraulic cylinder 201 according to the set program, including the extension speed of the piston rod, the extension stroke and the pressure holding time, thereby ensuring the standardization of the processing technology and the consistency of product quality, and reducing the reliance on manual experience.

[0027] To further enhance the stability and guiding performance of the buffer structure, the first spring 205 is arranged coaxially around the outside of the sliding column 204. This structure allows the spring force of the first spring 205 to be evenly applied within the annular area of ​​the first pressure plate 202 and the second pressure plate 203 during compression and rebound, effectively preventing lateral twisting or displacement of the spring due to uneven force. At the same time, the sliding column 204 also provides reliable radial support for the first spring 205, ensuring high stability and precise guidance of the entire pressure assembly during vertical reciprocating motion.

[0028] To adapt to the processing requirements of conveyor belts of different specifications and facilitate daily maintenance, the device also includes a molding plate 206, which is detachably connected to the bottom of the second pressure plate 203. The molding plate 206 is a key working component that directly contacts and applies pressure to the conveyor belt and transfers heat (if it includes a heating function). Its surface can be processed into specific patterns or shapes. By designing it as a detachable structure, users can quickly replace different types of molding plates 206 according to production tasks. When the surface of the molding plate 206 is worn or requires deep cleaning, it can also be easily removed for processing, which greatly improves the flexibility and maintainability of the equipment.

[0029] The top of the molding plate 206 is fixed with a pin plate 5, while the bottom of the second pressure plate 203 is fixed with a fixing frame 501 that engages with the pin plate 5. This engagement structure provides a quick positioning reference for the installation of the molding plate 206. When the pin plate 5 is inserted into the fixing frame 501, the two are precisely positioned in the horizontal direction, laying the foundation for subsequent locking operations and ensuring the accuracy of installation and repeatability of positioning.

[0030] To enable quick locking and unlocking between the pin plate 5 and the fixed frame 501, a pull rod 502 is slidably installed inside the pin plate 5. A positioning post 504 is also fixedly connected to the pull rod 502. One end of the pull rod 502 extends out of the pin plate 5 and serves as a manually operated part. Its linear sliding inside the pin plate 5 will directly drive the positioning post 504 to move in the radial direction. The positioning post 504 is the actuator that realizes the locking function. Its extended or retracted state determines whether the pin plate 5 and the fixed frame 501 are locked.

[0031] To enable the positioning pin 504 to automatically return to the locked position, the device also includes a second spring 503, please refer to... Figure 4 The second spring 503 is sleeved on the pull rod 502, and the two ends of the second spring 503 abut against the inner wall of the positioning post 504 and the pin plate 5 respectively. In the natural state, the second spring 503 is in the relaxed state, and its stored elastic energy pushes the positioning post 504 to remain in the outward extended position, which is the default locked position.

[0032] In order to cooperate with the positioning pin 504 to form a lock, the fixed frame 501 is provided with a positioning hole for the positioning pin 504 to pass through. When the pin plate 5 is fully inserted into the fixed frame 501, the positioning pin 504 inside the pin plate 5 is exactly aligned with the positioning hole on the fixed frame 501. Under the elastic force of the second spring 503, the positioning pin 504 will automatically and instantaneously pass into the positioning hole, thereby firmly locking the pin plate 5 inside the fixed frame 501, which can effectively resist the vibration and impact generated during the processing.

[0033] To enhance the stability and smoothness of the pull rod 502 during operation, a sliding plate 505 is fixedly connected to the end of the pull rod 502 away from the positioning post 504. The sliding plate 505 is slidably disposed inside the fixed frame 501, and the sliding plate 505 forms a sliding fit with the inner wall of the fixed frame 501, providing additional guidance and support for the linear movement of the pull rod 502. This effectively prevents shaking, tilting or jamming caused by single-point force when pulling the pull rod 502, ensuring the smoothness and reliability of the entire unlocking action.

[0034] Working principle: First, the semi-finished conveyor belt to be processed is placed inside the mold frame 4. The operator starts the equipment through the controller 3. The piston rod of the hydraulic cylinder 201 extends downward, pushing the first pressure plate 202 downward. When the molding plate 206 contacts the conveyor belt and generates a reaction force, the first pressure plate 202 continues to move downward, which will compress the first spring 205 between the first pressure plate 202 and the second pressure plate 203. The compression process of the first spring 205 provides a buffer for the downward stroke, avoiding instantaneous impact force. At the same time, the continuous elastic force released by the compressed first spring 205 and the pressure of the hydraulic cylinder 201 work together on the second pressure plate 203 and the molding plate 206, making the overall pressure applied to the conveyor belt more uniform, completing the pressure molding and vulcanization.

[0035] After the shaping is completed, the controller 3 controls the piston rod of the hydraulic cylinder 201 to retract, and the first pressure plate 202 drives the entire pressure assembly to reset. The operator lifts the handle 405 upwards, and the handle 405 drives the connecting rod 402 to move under the guidance of the limiting groove 403 through the connecting plate 404. The other end of the connecting rod 402 pushes the lifting plate 401 at the bottom of the model frame 4 upwards, thereby lifting the formed conveyor belt above the upper edge of the model frame 4 for easy and quick removal of parts.

[0036] When it is necessary to disassemble the molding plate 206, the operator pulls the pull rod 502 outward. The pull rod 502 drives the positioning post 504 and the sliding plate 505 to compress the second spring 503, so that the positioning post 504 disengages from the positioning hole of the fixed frame 501. At this time, the locking state between the pin plate 5 and the fixed frame 501 is released, and the entire molding plate 206 can be easily removed from the second pressure plate 203.
