[0002] Vulcanization is a very important process that directly affects the performance of the product. The current vulcanization process is a direct-flow vulcanization equipment, in which the billet is continuously fed in from the inlet end, passes through the vulcanization sections such as heating, pressurization and heat preservation, and is directly pulled out from the outlet end without reciprocating or circulating action in between.

[0003] In the above method, when the parts are vulcanized by the DC vulcanizing equipment, the parts come into contact with the placement area, resulting in different vulcanization effects on the contact surface and non-contact surface, which affects the uniformity of vulcanization and further affects the quality of vulcanization. Summary of the Invention

[0004] The purpose of this invention is to provide a two-stage vulcanization device.

[0005] The technical problem solved by this invention is to solve the problem of uneven vulcanization effect on the contact surface caused by the use of DC vulcanization equipment in the prior art.

[0007] A further technical improvement of the present invention is that: the vulcanizing roller is installed at the output end of the vulcanizing motor, and the vulcanizing motor is fixedly installed inside the vulcanizing box, and an end shaft is rotatably provided inside the vulcanizing box, and the end shaft is fixedly connected to the vulcanizing roller.

[0008] A further technical improvement of the present invention is that: the vulcanizing roller includes a roller body and an arc-shaped plate for receiving unloading materials, the distance between the arc-shaped plate for receiving unloading materials and the roller body is adjustable, and the arc-shaped plate for receiving unloading materials forms a cylindrical shape with the roller body when it is in its original position.

[0009] A further technical improvement of the present invention is that: the loading and unloading receiving arc plate is installed at the output end of the rotating motor, the rotating motor is fixedly installed on the first rotating base, the first rotating base is installed at the output end of the longitudinal moving equipment, and the end of the loading and unloading receiving arc plate away from the first rotating base is rotatably installed on the second rotating base.

[0010] A further technical improvement of the present invention is that: the longitudinal moving device includes a push base, the push base is fixedly installed on the output end of the drum body and the vulcanizing motor respectively, a screw assembly is provided on the push base, a push rod is provided at the output end of the screw assembly, and the push rod is fixedly connected to the first rotating base and the second rotating base respectively.

[0011] A further technical improvement of the present invention is that: an isolation plate is fixed inside the roller body, a groove is provided on the loading and unloading receiving arc plate for cooperating with the isolation plate, and a first inlet and a second inlet are provided on the top of the vulcanizing box for feeding parts.

[0012] A further technical improvement of the present invention is that: a first feeding box and a second feeding box for unloading parts are fixed at the bottom of the vulcanizing box, and a connecting base plate for collecting impurities is symmetrically arranged above the first feeding box and the second feeding box, and the distance between adjacent connecting base plates is adjustable.

[0013] A further technical improvement of the present invention is that: the connecting base plate is fixedly installed on the torsion spring base, a screw assembly is provided inside the vulcanizing box, an edge sliding block is provided at the output end of the screw assembly, the edge sliding block and the torsion spring base are rotatably connected by the torsion spring, and an edge discharge groove for realizing the discharge of impurities is provided on the connecting base plate.

[0014] A further technical improvement of the present invention is that: an edge arc plate is fixed at the edge of the connecting base plate, and an inclined first contact surface is fixed inside the vulcanizing box, the first contact surface and the edge arc plate cooperating.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This application utilizes an internally rotatable vulcanizing roller design to continuously rotate the parts during the vulcanization process, avoiding prolonged contact with a fixed contact surface. This completely solves the problem of inconsistent vulcanization effects caused by uneven heating and pressure between the contact and non-contact surfaces in traditional DC equipment, ensuring the consistency of performance across all parts of the parts. Furthermore, this application employs an openable and rotatable arc-shaped loading and unloading plate controlled by a motor and screw assembly, enabling automatic receiving, pouring into the roller, and automatic unloading after vulcanization of the parts. This significantly reduces manual intervention and improves the automation level and production efficiency of the production process.

[0016] 2. This application sets up an isolation plate inside the drum to divide the inner cavity of the drum into two areas. This can accommodate parts from the two feed ports for initial differentiation, and also limit the tumbling range of parts in each area, effectively avoiding the problem of insufficient internal vulcanization caused by a large accumulation of parts.

[0017] 3. The equipment in this application is equipped with a movable, vibrating, and tiltable connecting base plate forming an impurity collection assembly at its bottom. This assembly can receive and collect impurities that fall from the parts during the vulcanization process, and automatically discharges the impurities into a dedicated collection box via the edge discharge chute before unloading, effectively preventing impurities from mixing into the finished parts and ensuring the cleanliness of the product.

[0018] 5. During the unloading process of this application, the lowering height of the arc-shaped plate receiving the unloading can be controlled to tilt the parts into the unloading box at a lower position, which greatly reduces the impact force when the parts fall and the possible bump damage. At the same time, the moving and avoidance design of the impurity collection component also provides unobstructed space for unloading. Attached Figure Description

Detailed Implementation

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] Please see Figure 1-4 As shown, a two-stage vulcanization device includes a vulcanization chamber 1 for vulcanizing parts. The top of the vulcanization chamber 1 has a first inlet 7 and a second inlet 8 for parts to enter. Inside the vulcanization chamber 1, a vulcanization roller 6 is rotatably mounted to receive and vulcanize the parts. A feeding mechanism is located at the bottom of the vulcanization chamber 1 for discharging the parts. A cabinet door is located on the side of the vulcanization chamber 1 for removing the feeding mechanism, facilitating the unloading of the vulcanized finished parts. This technical solution... In the process, the parts are first placed through the first inlet 7 and the second inlet 8 before vulcanization. The parts are placed inside the vulcanizing roller 6. The rotation of the vulcanizing roller 6 drives the parts inside the vulcanizing roller 6 to rotate. During the rotation, there is no fixed contact surface between the parts and the vulcanizing roller 6 to ensure uniform vulcanization of the parts. At the same time, the rotation of the vulcanizing roller 6 can throw out impurities in the parts, thereby ensuring the cleanliness of the parts. The cleaned parts are then unloaded by the unloading mechanism to obtain the finished parts.

[0024] As a further embodiment of this application, in order to realize the rotation of the vulcanizing roller 6, a vulcanizing mounting base 10 is fixedly installed inside the vulcanizing chamber 1, and a vulcanizing motor 9 is fixedly installed inside the vulcanizing mounting base 10. The vulcanizing roller 6 is provided at the output end of the vulcanizing motor 9, and an end shaft 18 is fixedly installed at the end of the vulcanizing roller 6 away from the vulcanizing motor 9. An end mounting seat 19 is fixedly installed inside the vulcanizing chamber 1, and the end mounting seat 19 and the end shaft 18 are rotatably connected. Therefore, in use, the starting of the vulcanizing motor 9 drives the rotation of the vulcanizing roller 6, thereby driving the rotation of the end shaft 18, so that the end shaft 18 rotates around the end mounting seat 19, further realizing the rotation of the vulcanizing roller 6, and ensuring uniform vulcanization of the parts inside the vulcanizing chamber 1.

[0025] To facilitate the loading and unloading of parts, the vulcanizing roller 6 in this application includes a roller body 22 and an arc-shaped loading and unloading receiving plate 13. The roller body 22 and the arc-shaped loading and unloading receiving plate 13 form a cylindrical roller. Both the roller body 22 and the arc-shaped loading and unloading receiving plate 13 are provided with a number of mesh holes for contacting heat. The arc-shaped loading and unloading receiving plate 13 and the roller body 22 can be separated. When the arc-shaped loading and unloading receiving plate 13 and the roller body 22 are separated, the parts can be loaded and unloaded. When the arc-shaped loading and unloading receiving plate 13 and the roller body 22 are in contact, uniform vulcanization inside the vulcanizing roller 6 can be achieved.

[0026] To achieve the separation and connection of the loading / unloading receiving arc plate 13 and the roller body 22, a push base 21 is installed at the output end of the vulcanizing motor 9 and the end of the end shaft 18. A push groove 20 is formed inside the push base 21, and a push screw 16 is rotatably mounted inside the push groove 20. The push screw 16 is driven by a push motor, and a push slider 23 is threaded onto the push screw 16. The push slider 23 is slidably connected to the push groove 20. A push rod 17 is fixedly mounted on the side of the push slider 23, and a first rotating base 12 and a second rotating base 15 are fixedly mounted on the push rod 17. The loading / unloading receiving arc plate 13 is installed at the output end of the rotating motor 11, and the loading / unloading receiving arc plate 13 and the second rotating base 15 are rotatably connected. The rotating motor 11 is fixedly mounted on the first rotating base 12. The push base 21 and the roller body 22 are fixedly connected. Therefore, in use, the push motor first drives the push screw 16, so that the threaded push slider 23 moves longitudinally under the sliding limit action of the push groove 20, thereby controlling the height of the first rotating base 12 and the second rotating base 15, so that the loading and unloading receiving arc plate 13 and the roller body 22 are separated until they are separated to a certain height. Then, the rotation motor 11 is started to control the loading and unloading receiving arc plate 13 to rotate. Then, the parts are put in from the first inlet 7 and the second inlet 8. The rotation of the loading and unloading receiving arc plate 13 tilts the parts into the inside of the roller body 22. Then, the height of the loading and unloading receiving arc plate 13 is controlled so that the loading and unloading receiving arc plate 13 and the roller body 22 form a complete roller, thereby fully vulcanizing the parts.

[0027] As a further embodiment of this application, in order to fully vulcanize the parts, in actual production, if a large number of parts are poured, they are very easy to accumulate. Therefore, in this application, an isolation plate 14 is fixedly installed inside the roller body 22, and a groove for cooperating with the isolation plate 14 is opened on the loading and unloading receiving arc plate 13. So, in use, the isolation plate 14 is used to place the parts in two areas of the roller body 22 respectively. When rotating, the rotation range of the parts is restricted, so that the parts can be fully vulcanized. At the same time, when the loading and unloading receiving arc plate 13 receives the parts from the first inlet 7 and the second inlet 8 respectively, the parts are roughly distinguished. Then, the parts are poured into another area of ​​the roller body 22 in almost half, thereby realizing the separation of the parts.

[0028] When parts collide under the action of the roller body 22, impurities on the parts or generated impurities are very likely to fall off under the action of gravity. In order to collect the impurities, this application provides an impurity collection component 2 and an impurity storage box 3 at the bottom of the vulcanizing box 1. The impurity storage box 3 is installed at both ends of the vulcanizing box 1, and a first feeding box 4 and a second feeding box 5 are respectively installed at the middle position of the bottom of the vulcanizing box 1 for feeding almost half of the parts. During this process, since the height of the loading and unloading receiving arc plate 13 is adjustable, the parts carried by the loading and unloading receiving arc plate 13 can be lowered to a certain height and tilted into the interior of the first feeding box 4 and the second feeding box 5 to reduce the damage to the parts caused by the impact.

[0029] The impurity collection component 2 includes a connecting base plate 30, and a connecting inclined plate 29 is provided at the edge contact position of the connecting base plate 30. In use, the connecting inclined plates 29 are in contact with each other, and the connecting base plate 30 can slide laterally. When the connecting base plates 30 are in contact with each other, impurities fall onto the position of the connecting base plate 30 and are collected by the connecting base plate 30. At the same time, an edge discharge groove 31 is opened on the connecting base plate 30 for impurity discharge. In use, impurities are discharged from the edge discharge groove 31 and poured into the impurity collection box 3 for collection. In this process, impurities can be effectively collected. In addition, during the vulcanization process of the parts, the connecting base plate 30 is used to shield the first discharge box 4 and the second discharge box 5 to prevent impurities from entering the interior of the first discharge box 4 and the second discharge box 5.

[0030] To enable lateral movement of the connecting base plate 30, a torsion spring base 28 is fixedly installed on the connecting base plate 30. The torsion spring base 28 is rotatably mounted on the edge sliding block 27 via a torsion spring. The edge sliding block 27 is threadedly connected to the edge screw 25. That is, a vulcanizing base is fixed inside the vulcanizing box 1. An edge groove 26 is formed on the vulcanizing base. The edge screw 25 is rotatably mounted inside the edge groove 26, and the edge sliding block 27 is slidably connected to the edge groove 26. The edge screw 25 is driven by the edge motor 24. Therefore, in use, the starting of the edge motor 24 controls the rotation of the edge screw 25, causing the edge sliding block 27 threaded on the edge screw 25 to slide laterally, controlling the position of the connecting base plate 30, thereby removing the connecting base plate 30 from the first feeding box 4 and the second feeding box 5, facilitating the unloading of parts.

[0031] A mating mechanism for engaging with a connecting base plate 30 is fixedly installed on the side of the vulcanizing chamber 1. An edge arc plate 32 is fixed at the edge of the connecting base plate 30. A mating base 33 is fixedly installed inside the vulcanizing chamber 1. A vibration groove 39 is formed on the mating base 33, and a vibration spring 34 (tension spring) is fixedly installed inside the vibration groove 39. A vibration slide plate 36 is fixed to the end of the vibration spring 34, and the vibration slide plate 36 is slidably connected to the vibration groove 39. A vibration connecting rod 38 is fixed to the end of the vibration slide plate 36, and a first contact surface 37 is fixed to the end of the vibration connecting rod 38. The side of the 37 is vertically fixed with a protective contact surface 35. During use, under the tension of the vibration spring 34, the edge arc plate 32 first contacts the highest position of the first contact surface 37. At this time, the edge arc plate 32 gradually contacts the lower end of the first contact surface 37, causing the edge arc plate 32 to rotate to a certain extent. This rotation needs to overcome the force of the torsion spring, causing the connecting base plate 30 to rotate. At this time, under the action of the vibration spring 34, the connecting base plate 30 vibrates slightly, causing the impurities on the connecting base plate 30 to be discharged under the action of the inclined connecting base plate 30 until they fall from the edge discharge groove 31 into the impurity collection box 3 for collection.

[0032] In use, the present invention first uses a drive motor to drive the drive screw 16, so that the threaded push slider 23 moves longitudinally under the sliding limit action of the push groove 20, thereby controlling the height of the first rotating base 12 and the second rotating base 15, so that the loading and unloading receiving arc plate 13 and the roller body 22 are separated until they are separated to a certain height. Then, the rotation motor 11 is started to control the loading and unloading receiving arc plate 13 to rotate. Then, the parts are put in from the first inlet 7 and the second inlet 8. The rotation of the loading and unloading receiving arc plate 13 tilts the parts into the inside of the roller body 22. Then, the height of the loading and unloading receiving arc plate 13 is controlled so that the loading and unloading receiving arc plate 13 and the roller body 22 form a complete roller, thereby fully vulcanizing the parts. After vulcanization, the edge motor 24 is started to control the rotation of the edge screw 25, causing the edge sliding block 27, which is threaded onto the edge screw 25, to slide laterally, controlling the position of the connecting base plate 30, thereby removing the connecting base plate 30 from the first feeding box 4 and the second feeding box 5. Then, under the tension of the vibration spring 34, the edge arc plate 32 first contacts the highest position of the first contact surface 37. At this time, the edge arc plate 32 gradually contacts the lower end of the first contact surface 37, causing the edge arc plate 32 to rotate to a certain extent. This rotation needs to overcome the force of the torsion spring, causing the connecting base plate 30 to rotate. At this time, under the action of the vibration spring 34, the connecting base plate 30 vibrates slightly, causing impurities on the connecting base plate 30 to be discharged under the action of the inclined connecting base plate 30, until they fall from the edge feeding groove 31 into the impurity collection box 3 for collection. Subsequently, under the action of the vulcanizing motor 9, the loading and unloading receiving arc plate 13 is rotated to the bottom of the drum body 22, and then the loading and unloading receiving arc plate 13 is separated from the drum body 22, and the loading and unloading receiving arc plate 13 is flipped to realize the unloading function.
