Description

Technical Field

[0001] This utility model relates to the technical field of pressurizing vulcanizing machines, and in particular to a pressurizing device for a conveyor belt vulcanizing joint machine. Background Technology

[0002] In modern industrial production, conveyor belts, as key equipment for material handling, are widely used in mining, ports, building materials, chemicals, and many other fields. The continuous and efficient operation of conveyor belts is crucial for ensuring the smooth operation of production lines. However, due to long-term operation, environmental factors, or accidental damage, conveyor belts inevitably experience wear and breakage, requiring timely repair or replacement of joints. Conveyor belt vulcanized splices, as a common repair method, are widely used in the maintenance and repair of various types of conveyor belts due to their high joint strength and long service life.

[0003] In the vulcanization splicing process of conveyor belts, pressurization is one of the key steps to ensure splice quality. Applying appropriate pressure allows the vulcanizing agent to be evenly distributed at the conveyor belt splice, promoting the cross-linking reaction between rubber molecules and forming a strong splice structure. Traditional pressurization methods for conveyor belt vulcanization splicing often use manual or simple mechanical pressurization devices. Manual or simple mechanical pressurization methods make it difficult to achieve precise pressure control. Excessive pressure may lead to over-compression of the conveyor belt material, affecting splice quality; insufficient pressure will not ensure sufficient penetration of the vulcanizing agent, resulting in insufficient splice strength. Traditional pressurization methods often require frequent manual adjustments, which is not only labor-intensive but also time-consuming, failing to meet the demands of modern production for efficient and rapid repair. Operating under high pressure also poses safety hazards with traditional pressurization devices, such as equipment damage or personal injury due to uncontrolled pressure. Utility Model Content

Detailed Implementation

[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0037] like Figures 1 to 4 As shown, the pressurizing device for the conveyor belt vulcanizing joint machine of this utility model includes:

[0038] Main support frame 1 is mounted on the ground;

[0039] The pressure support 11 is mounted on the main support 1;

[0040] The pressurizing mechanism 2, mounted on the pressurizing bracket 11, is used to apply pressure;

[0041] Hydraulic cylinder 21, mounted on pressure bracket 11, is used to provide pressure action;

[0042] Both connector assemblies 3 are connected to the hydraulic cylinder 21 and are used to supply hydraulic oil to the hydraulic cylinder 21;

[0043] The pressurizing mechanism 2 includes:

[0044] The top pressure plate 22 is slidably disposed in the pressure bracket 11;

[0045] Connector 23 is fixedly installed at the bottom end of top pressure plate 22;

[0046] Quick-connect block 24 is slidably mounted in connector 23;

[0047] The pressure plate 25 is movable up and down in the main support 1, and the top of the pressure plate 25 is fixedly connected to the quick-connect block 24.

[0048] The working process and principle of the device are as follows: The conveyor belt joint to be vulcanized is placed in a suitable position below the pressure plate 25, ensuring alignment of both ends for subsequent pressurization. Hydraulic oil is injected into the hydraulic cylinder 21 via the joint assembly 3 to prepare for the pressurization action. At this time, the top pressure plate 22 is in its initial position within the pressure support 11, and the pressure plate 25 is also located at a higher position within the main support 1, without applying pressure to the conveyor belt joint. The hydraulic cylinder 21 is activated, and the hydraulic oil, under pressure, pushes the top pressure plate 22 downwards within the pressure support 11. Since the connecting seat 23 is fixedly installed at the bottom of the top pressure plate 22, the quick-connect block… The 24-sliding clamp is installed in the connecting seat 23, and the top of the pressure plate 25 is fixedly connected to the quick-connect block 24. Therefore, the downward movement of the top pressure plate 22 will drive the pressure plate 25 to move downward in the main support 1, applying uniform pressure to the conveyor belt joint. Under the action of the hydraulic cylinder 21, the pressure plate 25 continuously applies stable pressure to the conveyor belt joint, so that the vulcanizing agent is evenly distributed at the joint and promotes the cross-linking reaction between rubber molecules. At this time, according to the vulcanization process requirements, a certain pressure and time are maintained to ensure the joint quality. After vulcanization is completed, the hydraulic oil in the hydraulic cylinder 21 is extracted by controlling the joint assembly 3, so that the hydraulic cylinder 21 is reset and the top pressure plate... 22 rises accordingly, causing the pressure plate 25 to rise to its initial position. At this point, the conveyor belt joint has completed vulcanization and can be removed from the device for subsequent processing or installation. This device uses a hydraulic cylinder 21 to provide pressure action. By controlling the flow and pressure of the hydraulic oil, precise control of the pressure applied to the conveyor belt joint can be achieved. This avoids the problems of excessive or insufficient pressure in traditional manual or simple mechanical pressurization methods, ensuring joint quality. The pressurization action of the hydraulic cylinder 21 is fast and stable, reducing frequent manual pressure adjustments and lowering labor intensity. Simultaneously, the device can continuously and stably apply pressure. The hydraulic transmission method has… It features overload protection; when the pressure exceeds the set value, the hydraulic system automatically releases pressure to prevent equipment damage or personal injury. This device can adjust the pressure and pressurization time according to different specifications and materials of conveyor belt joints to adapt to diverse joint requirements, improving the device's versatility and flexibility while reducing production costs. By precisely controlling the pressure and maintaining a stable pressurization time, the device ensures that the vulcanizing agent is evenly distributed at the conveyor belt joint, promoting full cross-linking reactions between rubber molecules and forming a robust joint structure. This improves the strength and service life of the conveyor belt joint, reducing maintenance costs and the risk of production interruption.

[0049] Two guide sliders 26 are symmetrically arranged on both sides of the top pressure plate 22, and two slide rails 27 are symmetrically arranged on the inner wall of the pressure bracket 11. The two guide sliders 26 are respectively slidably locked onto the two slide rails 27. The cooperation between the guide sliders 26 and the slide rails 27 provides precise guidance for the up and down movement of the top pressure plate 22, preventing the top pressure plate 22 from shifting or shaking during movement. This ensures that the pressure plate 25 can accurately and stably apply pressure to the conveyor belt joint, improving the accuracy and reliability of pressurization. During the pressurization process, due to the constraint of the guide sliders 26 and slide rails 27, the movement of the top pressure plate 22 is more stable, reducing pressure fluctuations caused by vibration, and further ensuring the stability of the joint quality. The guide sliders 26 and slide rails 27 can prevent the top pressure plate 22 from shifting during movement. The structure prevents jamming; if the top pressure plate 22 does not move smoothly, it may lead to unstable pressure or even damage to the device. This structure ensures that the top pressure plate 22 can move smoothly up and down, improving the safety and reliability of the device. When operating in a high-pressure environment, if the movement of the top pressure plate 22 is unstable, it may cause the equipment to bear excessive lateral force, thereby damaging the equipment. The cooperation between the guide slider 26 and the slide rail 27 can effectively disperse and bear these lateral forces, protecting the equipment from damage. The sliding cooperation between the guide slider 26 and the slide rail 27 reduces friction and wear compared to the top pressure plate 22 directly contacting the inner wall of the pressure bracket 11. This helps to extend the service life of the top pressure plate 22, the pressure bracket 11, and related components, reducing the maintenance cost of the equipment.

[0050] Two limiting posts 28 are symmetrically arranged on the pressure support 11, and the limiting posts 28 are located at the bottom of the slide rail 27. The limiting posts 28 can precisely control the downward distance of the top pressure plate 22, thereby ensuring that the pressure applied by the pressure plate 25 to the conveyor belt joint is within a suitable range. This avoids the problem of excessive compression of the conveyor belt material due to excessive pressure, which affects the joint quality, and insufficient pressure, which fails to ensure sufficient penetration of the vulcanizing agent, resulting in insufficient joint strength. By precisely controlling the pressure, the vulcanizing agent can be evenly distributed at the conveyor belt joint, promoting a more complete cross-linking reaction between rubber molecules, forming a stronger joint structure, and improving the quality of the conveyor belt vulcanized joint. During the pressurization process, without the restriction of the limiting posts 28, the top pressure plate 22 may continue to descend due to excessive pushing by the hydraulic cylinder 21, leading to... Excessive pressure applied to the conveyor belt joint by the pressure plate 25 can damage not only the conveyor belt but also the pressurizing device itself. The presence of the limit post 28 prevents this from happening, protecting the equipment and the conveyor belt. In high-pressure environments, uncontrolled pressure can lead to equipment damage or even personal injury. The limit post 28 ensures the pressure remains within a safe range, reducing the risk of accidents and protecting the safety of operators. The limit post 28 provides a stable downward endpoint for the pressurizing mechanism 2, ensuring that each pressurizing operation stops at the same position, guaranteeing the stability and reliability of the device. Precise pressure control reduces equipment failures caused by abnormal pressure, extends the device's lifespan and maintenance cycle, and lowers production costs.

[0051] Two guide rods 29 are symmetrically arranged on the main support 1. The guide rods 29 slide and engage with the pressure plate 25. The sliding engagement of the guide rods 29 and the pressure plate 25 provides vertical guidance for the pressure plate 25, ensuring that the pressure plate 25 always moves in the vertical direction during the pressurization process. This avoids uneven pressure caused by offset or shaking, thereby improving the quality of the conveyor belt vulcanization joint. The stable movement trajectory allows the pressure plate 25 to accurately transmit the pressure provided by the hydraulic cylinder 21 to the conveyor belt joint, ensuring the accuracy of pressurization and facilitating the formation of a robust joint structure. The presence of the guide rods 29 restricts the degree of freedom of the pressure plate 25, reducing friction and collision between the pressure plate 25 and other components during movement, reducing the wear and tear on the equipment, and extending the service life of the equipment.

[0052] like Figure 3 As shown, connector assembly 3 includes:

[0053] Quick-connect male connector 31 is connected to hydraulic cylinder 21, and a fastening groove 33 is provided on quick-connect male connector 31;

[0054] The quick-connect female connector 32 is connected to the quick-connect male connector 31 and to an external oil pipe. A sliding sleeve 34 is slidably fitted on the outer wall of the quick-connect female connector 32. A spring groove is provided on the inner wall of the sliding sleeve 34 and the outer wall of the quick-connect female connector 32. A fastening spring 35 is provided in the spring groove and provides thrust to the sliding sleeve 34. Several locking beads 36 are arranged circumferentially at the port of the quick-connect female connector 32. When the quick-connect female connector 32 is fitted onto the quick-connect male connector 31, the two are fixed by locking the locking beads 36 into the fastening groove 33.

[0055] Two self-sealing components are provided in both quick-connect male connector 31 and quick-connect female connector 32;

[0056] The working process and principle of the connector assembly 3 are as follows: Pull the sliding sleeve 34, and then the operator aligns the quick-connect female connector 32 with the quick-connect male connector 31, and slowly pushes the quick-connect female connector 32 towards the quick-connect male connector 31; as the quick-connect female connector 32 gradually slides into the quick-connect male connector 31, the end of the quick-connect male connector 31 will gradually push open the locking ball 36 at the port of the quick-connect female connector 32; as the insertion depth increases, when the fastening groove 33 on the quick-connect male connector 31 corresponds to the position of the locking ball 36, under the pushing force of the fastening spring 35, the sliding sleeve 34 pushes the locking ball 36 into the fastening groove 33, thereby fixing the quick-connect male connector 31 and the quick-connect female connector 32 together; then release the sliding sleeve 34, and the sliding sleeve 34 resets under the pushing force of the fastening spring 35, fixing the locking ball 36; when disassembly is required, the operator moves away from the quick-connect... Pulling the sliding sleeve 34 in the direction of the male connector 31 overcomes the thrust of the fastening spring 35, causing the locking ball 36 to disengage from the fastening groove 33. After the locking ball 36 disengages from the fastening groove 33, the operator can easily pull the quick-connect female connector 32 off the quick-connect male connector 31. The connection between the quick-connect male connector 31 and the quick-connect female connector 32 is simple and quick. Quick connection and disassembly can be achieved through the cooperation of the sliding sleeve 34 and the locking ball 36, which greatly improves work efficiency and reduces equipment downtime. The locking ball 36 is locked in the fastening groove 33, which can provide reliable connection force and ensure that the connector will not loosen or fall off during the pressurization process, thus ensuring the normal operation of the pressurization device of the conveyor belt vulcanizing joint machine. The quick connection and disassembly method reduces the contact time between the operator and the hydraulic oil, reducing the risk of hydraulic oil splashing and injury caused by improper operation.

[0057] like Figures 3 to 4 As shown, the self-encapsulated component includes:

[0058] Self-locking block 37, a sealing cone surface is provided on the self-locking block 37, a collision protrusion is provided on the outer end of the sealing cone surface, and a spring pressure groove is provided on the self-locking block 37;

[0059] The self-locking spring 38 is disposed inside the quick-connect male connector 31 and quick-connect female connector 32, and fits into the spring groove of the self-locking block 37. Under the elastic force of the self-locking spring 38, the sealing cone surface of the self-locking block 37 is pressed tightly against the inner end face of the quick-connect male connector 31 or quick-connect female connector 32 for sealing. When the self-locking spring 38 is compressed, it means that the collision protrusion of the self-locking block 37 is under force, and the entire self-locking block 37 will slide, thereby causing the sealing cone surface to separate from the inner end face of the quick-connect male connector 31 or quick-connect female connector 32, thus creating a gap for hydraulic oil to flow. In other words, only when the self-locking spring 38 is compressed can the hydraulic oil flow through the gap. The quick-connect female connector 32 is fitted onto the quick-connect male connector 31. The collision protrusions of the two self-locking blocks 37 on the quick-connect female connector 32 and the quick-connect male connector 31 collide and generate mutual thrust, causing the two self-locking blocks 37 to compress their respective self-locking springs 38, creating gaps in both the quick-connect male connector 31 and the quick-connect female connector 32 to ensure the flow of hydraulic oil. When the quick-connect male connector 31 and the quick-connect female connector 32 are separated, the self-locking blocks 37 will return to their original position under the elastic force of the self-locking springs 38, causing the sealing cone surface to fit against the inner walls of the quick-connect male connector 31 and the quick-connect female connector 32, thereby achieving a sealing effect.

[0060] The working process and principle of the self-locking assembly are as follows: When the quick-connect female connector 32 is gradually inserted into the quick-connect male connector 31, the collision protrusions on the self-locking blocks 37 of both begin to contact each other; as the quick-connect female connector 32 is inserted deeper, the thrust between the collision protrusions gradually increases, causing the two self-locking blocks 37 to compress their respective self-locking springs 38; after the self-locking springs 38 are compressed, the sealing cone surface of the self-locking block 37 separates from the inner end face of the quick-connect male connector 31 or the quick-connect female connector 32, forming a gap; these gaps allow hydraulic oil to flow between the quick-connect male connector 31 and the quick-connect female connector 32, providing pressure for the hydraulic cylinder 21; when the quick-connect female connector 32 is fully inserted into the quick-connect male connector 31, the self-locking blocks 37 of both remain in a certain compressed state under the thrust of the collision protrusions, ensuring continuous flow of hydraulic oil; although there is a gap between the sealing cone surface and the inner end face of the self-locking block 37, the size of this gap is stable due to the elasticity of the self-locking springs 38. Furthermore, it will not affect the normal flow of hydraulic oil. When it is necessary to disassemble the quick-connect female connector 32, the operator only needs to gently pull the quick-connect female connector 32 outward. As the quick-connect female connector 32 moves, the thrust between the collision protrusions gradually decreases, and the self-locking spring 38 begins to reset. After the self-locking spring 38 resets, the sealing cone surface of the self-locking block 37 once again tightly fits against the inner end face of the quick-connect male connector 31 or the quick-connect female connector 32, sealing the internal channel. When the quick-connect female connector 32 is completely pulled out from the quick-connect male connector 31, the self-sealing components of both return to the unconnected state. The self-sealing component ensures that hydraulic oil will not leak when the quick-connect male connector 31 and the quick-connect female connector 32 are not connected, avoiding environmental pollution and safety hazards caused by hydraulic oil leakage. Preventing hydraulic oil leakage also reduces hydraulic oil waste and lowers production costs. The design of the self-sealing component makes the connection and disassembly process of the quick-connect male connector 31 and the quick-connect female connector 32 simpler and faster, improving work efficiency.

[0061] like Figure 4 As shown, a sealing ring is fitted on the sealing cone surface of the self-locking block 37; the sealing ring has good elasticity and softness, which can fill the small gap at the connection between the quick-connect male connector 31 and the quick-connect female connector 32, effectively preventing hydraulic oil leakage; compared with the sealing cone surface of the self-locking block 37 alone, it increases the reliability of the seal and improves the overall sealing performance of the hydraulic system.

[0062] A sealing ring 39 is provided on the inner wall of the quick-connect female connector 32. The sealing ring 39 is used to seal the connection end between the quick-connect female connector 32 and the quick-connect male connector 31. The sealing ring 39 has good elasticity and sealing performance, and can fit tightly against the connection between the quick-connect male connector 31 and the quick-connect female connector 32, effectively preventing hydraulic oil leakage. Compared with the sealing cone surface seal relying solely on the self-locking block 37, it increases the reliability of the seal and improves the overall sealing performance of the hydraulic system. The sealing ring 39 can reduce the direct friction at the connection between the quick-connect male connector 31 and the quick-connect female connector 32, reducing wear. During the connection and disassembly of the quick-connect male connector 31 and the quick-connect female connector 32, the sealing ring 39 plays a certain buffering role, extending the service life of the quick-connect male connector 31 and the quick-connect female connector 32.

[0063] The pressurizing device for the conveyor belt vulcanizing joint machine of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0064] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
