Description

Technical Field

[0001] This utility model relates to the field of vulcanizing box technology, and more specifically, it relates to a vulcanizing box for mass-produced slippers. Background Technology

[0002] In existing technologies, adjusting the angle of the vulcanizing spray head in a vulcanizing box for mass-produced slippers presents several inconveniences. The installation and disassembly process before and after adjustment is cumbersome, which seriously affects production efficiency and vulcanization quality.

[0003] Specifically, the spray head angle adjustment mechanism in traditional slipper vulcanizing boxes typically uses a fixed bolt connection. Each time the spray angle needs to be adjusted, the operator must first loosen the fixed bolt, then manually adjust the spray head position, and finally retighten the bolt. This process is not only time-consuming and labor-intensive, but also makes it difficult to guarantee the accuracy and repeatability of the adjustment.

[0004] In actual production, due to the diversity of slippers' sizes and shapes, the spray head angle needs to be frequently adjusted to adapt to the vulcanization requirements of different batches of products. During frequent adjustments, traditional adjustment mechanisms are prone to wear on fixing bolts and connecting parts, leading to loose connections or spray head misalignment, affecting vulcanization uniformity and product quality.

[0005] In addition, the spray system of traditional vulcanizing boxes often requires complete disassembly of the spray head assembly during maintenance and cleaning. The disassembly process can easily damage the connecting parts, and it is difficult to restore the original optimal spray angle when reinstalling, resulting in inconsistent vulcanization effects.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a vulcanizing box for mass production of slippers, which has the following beneficial effects:

[0019] This invention features a spray rotation mechanism. Through multiple sets of adjustment holes on the arc plate and a sliding locking rod, the spray head angle can be quickly adjusted and switched, avoiding the cumbersome problem of spray head angle adjustment in traditional vulcanizing boxes. At the same time, the cooperation between the threaded rod and the threaded sleeve enables precise adjustment of the spray height, which can meet the vulcanization requirements of slippers of different thicknesses, improving adaptability and accuracy.

[0020] This utility model is equipped with a position fixing mechanism. By rotating the outer rotating sleeve, the inner toothed ring and the bidirectional toothed block are driven, thereby controlling the meshing state of the rotating toothed block and the locking rod groove. This achieves quick locking and releasing of the spray head position, making the adjustment operation simple and intuitive, which can be completed without tools. At the same time, it ensures the reliability and stability of locking and prevents the spray head from shifting position during use.

[0021] This utility model is equipped with a fixing auxiliary mechanism. Through the rolling contact between the counterweights on multiple sets of centripetal rails and the spherical blocks arranged in annularly at the bottom of the outer rotating sleeve, the rotational friction is reduced, and good contact is maintained under the action of the counterweight spring. This ensures that the outer rotating sleeve rotates smoothly and reliably, significantly improving the operational flexibility and service life of the position fixing mechanism, while also enhancing the stability and accuracy of the entire adjustment system.

[0031] Please see Figures 1-5 A vulcanizing box for mass production of slippers includes a placement plate 1, a box assembly 2, a spray rotation mechanism, a position fixing mechanism, and a fixing auxiliary mechanism. The spray rotation mechanism includes a spray head 3 and an arc plate 4. The top end of the spray head 3 is provided with a mounting plate 5. The arc plate 4 is fixedly installed inside the top end of the box assembly 2. The arc plate 4 has adjustment holes 6, and multiple sets of adjustment holes 6 are provided. A retaining tube 7 is fixedly installed on one end face of the mounting plate 5, and a retaining connector is slidably installed inside the retaining tube 7. The rod 8 can pass through different adjustment holes 6 and engage with the locking tube 7. The position fixing mechanism includes an inner toothed ring 9 and an outer rotating sleeve 10. The outer rotating sleeve 10 is rotatably mounted on the outer wall of the locking tube 7. The inner toothed ring 9 is mounted on the top end of the outer rotating sleeve 10. A locking groove 11 is provided on the side wall of the locking rod 8. A rotating tooth block 12 is rotatably mounted inside the side wall of the locking tube 7. A bidirectional tooth block 13 is installed between the rotating tooth block 12 and the inner toothed ring 9. The rotating tooth block 12 can be embedded in or away from the locking groove 11.

[0032] In this embodiment, the directional spraying of the vulcanizing liquid is achieved by the cooperation of the spray head 3 and the arc plate 4. During operation, the position fixing mechanism is first loosened, the position of the spray head 3 is adjusted, and the mounting plate 5 at the top of the spray head 3 is fixed with a clamping tube 7. The clamping rod 8 inside the clamping tube 7 can pass through different adjustment holes 6 on the arc plate 4. By selecting different positions of the adjustment hole 6, the angle and position of the spray head 3 can be changed, thereby adjusting the spray range and direction of the vulcanizing liquid. The threaded rod 23 on the spray head 3 cooperates with the threaded sleeve 24 at the bottom of the mounting plate 5, which can finely adjust the height of the spray head 3. The outer rotating sleeve 10 controls the meshing state of the rotating tooth block 12 and the locking groove 11 of the locking rod 8. When the spray head 3 is adjusted to the appropriate position, the outer rotating sleeve 10 is rotated, which drives the inner tooth ring 9 to rotate. The inner tooth ring 9 drives the rotating tooth block 12 to rotate through the bidirectional tooth block 13, so that the rotating tooth block 12 is embedded in the locking groove 11 on the side wall of the locking rod 8, thereby locking the position of the locking rod 8 and fixing the angle and position of the spray head 3. When it is necessary to readjust the spray head 3, the outer rotating sleeve 10 is rotated in the opposite direction, the rotating tooth block 12 is disengaged from the locking groove 11, the locking rod 8 is released, and the spray head 3 can be readjusted again.

[0033] The fixed auxiliary mechanism includes a connecting plate 14 and a radial rail 15. The connecting plate 14 is fixedly installed at the bottom end of the storage of the clamping tube 7. Multiple sets of radial rails 15 are arranged at the top end of the connecting plate 14. Each set of radial rails 15 is slidably mounted with opposing compression blocks 16. A compression spring 17 is installed between the opposing compression blocks 16. A ball block 18 is installed at the bottom end of the outer rotating sleeve 10. Multiple sets of ball blocks 18 are arranged in a ring at the bottom of the outer rotating sleeve 10. The ball blocks 18 pass through the opposing compression blocks 16 in sequence, so that the outer rotating sleeve 10 stably drives the inner toothed ring 9 to rotate.

[0034] In this embodiment, the fixing auxiliary mechanism ensures the stability of the rotation of the outer rotating sleeve 10 through the design of the connecting plate 14 and the radial rail 15. The connecting plate 14 is fixed to the bottom of the clamping tube 7 and is provided with multiple sets of radial rails 15. Each set of radial rails 15 is equipped with opposing sliding blocks 16. There are opposing springs 17 between the opposing blocks 16 to provide elastic force. The ball blocks 18 arranged in a ring at the bottom of the outer rotating sleeve 10 pass through the gap between the opposing opposing blocks 16 in sequence. When the outer rotating sleeve 10 rotates, the ball blocks 18 and the opposing blocks 16 form rolling contact to reduce friction. At the same time, the elasticity of the opposing springs 17 ensures that the ball blocks 18 and the opposing blocks 16 maintain good contact, so that the outer rotating sleeve 10 can stably drive the inner toothed ring 9 to rotate, thereby improving the reliability of the position fixing mechanism.

[0035] Please see Figures 1-5As a supplementary embodiment of a mass-produced slipper vulcanizing box for spray rotation mechanism, position fixing mechanism and fixing auxiliary mechanism: A door 19 is rotatably installed at the front opening end of the box assembly 2. Door locks 20 are installed on the side of the door 19 and the box assembly 2. Side blocks 21 are symmetrically installed on the inner wall of the box assembly 2. Sliding grooves 22 are opened on the side blocks 21. Multiple sets of side blocks 21 are provided. The two sides of the placement plate 1 are slidably installed in the sliding grooves 22. A threaded rod 23 is installed at the top end of the spray head 3. A threaded sleeve 24 is installed at the bottom end of the mounting plate 5. The threaded rod 23 is threadedly connected to the threaded sleeve 24. A supply pipe 25 is installed at one end of the spray head 3. One end of the supply pipe 25 can be connected to an external sulfur supply device. A rotation groove 26 is opened in the side wall of the clamping pipe 7. The rotating tooth block 12 is rotated in the rotation groove 26.

[0036] More specifically, open the front door 19 of the housing assembly 2, place the slippers to be vulcanized on the placement plate 1 in the sliding groove 22, close the door 19 and lock the door lock 20. Depending on the size and shape of the slippers, rotate the outer rotating sleeve 10 to release the position lock, adjust the locking rod 8 to pass through the appropriate adjustment hole 6 on the curved plate 4, and simultaneously adjust the height of the spray head 3 using the threaded rod 23 and threaded sleeve 24 to ensure the spray range covers all the slippers. After adjustment, rotate the outer rotating sleeve 10 to make the rotating tooth block 12 engage with the locking rod 8. In the slot 11, the ball block 18 in the fixed auxiliary mechanism cooperates with the shrink block 16 to ensure the outer rotating sleeve 10 rotates stably, thereby firmly locking the position of the spray head 3. The supply pipe 25 of the spray head 3 is connected to the external sulfur supply equipment to start supplying the vulcanizing liquid. The spray head 3 sprays the vulcanizing liquid at the preset position and angle to uniformly vulcanize the slippers on the placement plate 1. After vulcanization is completed, the supply pipe 25 is disconnected, the door 19 is opened, the vulcanized slippers are taken out, and the next batch of slippers to be vulcanized is placed in, and the above process is repeated.

[0037] In summary, during the use or operation of the overall equipment: when the spray rotation mechanism is in operation, the spray head 3 and the arc plate 4 work together to achieve directional spraying of the sulfiding liquid. During operation, first loosen the position fixing mechanism, adjust the position of the spray head 3. A clamping pipe 7 is fixed on the mounting plate 5 at the top of the spray head 3. The clamping rod 8 inside the clamping pipe 7 can pass through different adjustment holes 6 on the arc plate 4. By selecting different adjustment holes 6, the angle and position of the spray head 3 can be changed, thereby adjusting the spray range and direction of the sulfiding liquid. The threaded rod 23 on the spray head 3 cooperates with the threaded sleeve 24 at the bottom of the mounting plate 5, allowing for fine adjustment of the height of the spray head 3.

[0038] When the positioning mechanism is in operation, the outer rotating sleeve 10 controls the engagement state of the rotating tooth block 12 with the slot 11 of the locking rod 8. After the spray head 3 is adjusted to the appropriate position, the outer rotating sleeve 10 is rotated, which drives the inner tooth ring 9 to rotate. The inner tooth ring 9 drives the rotating tooth block 12 to rotate through the bidirectional tooth block 13, so that the rotating tooth block 12 is embedded in the slot 11 on the side wall of the locking rod 8, thereby locking the position of the locking rod 8 and fixing the angle and position of the spray head 3. When the spray head 3 needs to be readjusted, the outer rotating sleeve 10 is rotated in the opposite direction, the rotating tooth block 12 is disengaged from the slot 11, the locking rod 8 is released, and the spray head 3 can be readjusted again.

[0039] When the auxiliary mechanism needs to be fixed during operation, the design of the connecting plate 14 and the radial rail 15 ensures the stability of the rotation of the outer rotating sleeve 10. The connecting plate 14 is fixed to the bottom of the clamping tube 7 and is provided with multiple sets of radial rails 15. Each set of radial rails 15 is equipped with opposing sliding blocks 16. There are opposing springs 17 between the opposing blocks 16 to provide elastic force. The ball blocks 18 arranged in a ring at the bottom of the outer rotating sleeve 10 pass through the gap between the opposing opposing blocks 16 in sequence. When the outer rotating sleeve 10 rotates, the ball blocks 18 and the opposing blocks 16 form rolling contact to reduce friction. At the same time, the elasticity of the opposing springs 17 ensures that the ball blocks 18 and the opposing blocks 16 maintain good contact, so that the outer rotating sleeve 10 can stably drive the inner toothed ring 9 to rotate, thereby improving the reliability of the position fixing mechanism.

[0040] Open the front door 19 of the housing assembly 2, place the slippers to be vulcanized on the placement plate 1 in the sliding groove 22, close the door 19 and lock the door lock 20. According to the size and shape of the slippers, rotate the outer rotating sleeve 10 to release the position lock, adjust the locking rod 8 to pass through the appropriate adjustment hole 6 on the arc plate 4, and at the same time adjust the height of the spray head 3 through the threaded rod 23 and threaded sleeve 24 to ensure that the spray range covers all slippers. After adjustment, rotate the outer rotating sleeve 10 so that the rotating tooth block 12 is embedded in the slot of the locking rod 8. In step 11, the ball block 18 in the fixed auxiliary mechanism cooperates with the shrink block 16 to ensure the outer rotating sleeve 10 rotates stably, thereby firmly locking the position of the spray head 3. The supply pipe 25 of the spray head 3 is connected to the external sulfur supply equipment, and the sulfurizing liquid is supplied. The spray head 3 sprays the sulfurizing liquid at the preset position and angle to uniformly vulcanize the slippers on the placement plate 1. After the vulcanization is completed, the supply pipe 25 is disconnected, the door 19 is opened, the vulcanized slippers are taken out, and the next batch of slippers to be vulcanized is put in, and the above process is repeated.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.

The scope of this utility model is defined by the appended claims and their equivalents.
