Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic product processing technology, and in particular to a vulcanization device for processing rubber and plastic products. Background Technology

[0002] A vulcanizing machine is a machine used to vulcanize various rubber and plastic products. It has functions such as timed mold locking, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. Vulcanizing machines are divided into three types: electric heating, steam heating, and heat transfer oil heating. They are also known as flat vulcanizing machines, foam board vulcanizing machines, and rubber vulcanizing machines.

[0003] To address the aforementioned issues, existing patents offer solutions. However, existing rubber vulcanizing machines lack an automatic conveying structure for molds and materials. This necessitates manual handling of unvulcanized rubber materials into the molds, followed by pushing the molds containing the materials into the vulcanizing area of ​​the vulcanizing machine. After vulcanization, the molds must be manually removed from the vulcanizing area and transferred to the demolding station. Throughout the entire process, the conveying of materials and molds relies on manual operation. This not only involves cumbersome and time-consuming procedures but also easily leads to vulcanizing machines stopping due to inconsistent manual handling speeds, thereby reducing the overall production efficiency of the rubber vulcanizing machine.

[0004] Therefore, a vulcanization device for processing rubber and plastic products is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a vulcanization device for processing rubber and plastic products. This device addresses the problem that existing rubber and plastic product processing lacks an automatic conveying structure for molds and materials. As a result, manual handling is required to move unvulcanized rubber materials into the mold, push the mold containing the material to the vulcanization area of ​​the vulcanizing machine, and then manually remove the mold from the vulcanization area and transfer it to the demolding station after vulcanization. Throughout the process, the conveying of materials and molds relies on manual operation, which is not only cumbersome and time-consuming, but also prone to causing the vulcanizing machine to stop due to inconsistent manual handling speed, thus reducing the overall production efficiency of the rubber vulcanizing machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vulcanizing device for processing rubber and plastic products, comprising a vulcanizing machine body, with conveying mechanisms welded to both sides of the top of the vulcanizing machine body, and a connecting mechanism welded to the top of the conveying mechanism. The conveying mechanism includes an mounting plate, two limiting rods, a lead screw, a stepper motor, a threaded sleeve, a slider, and a PLC controller. The mounting plate is welded to the front side and the rear side of the top of the vulcanizing machine body, respectively. The limiting rods are welded to both sides of the front side of the rear mounting plate, and the front side of the limiting rods is welded to the rear side of the front mounting plate. The lead screw is rotatably connected to the front side of the rear mounting plate and the rear side of the front mounting plate. A connecting shaft is connected to the rear side of the lead screw via a flat key.

[0007] Preferably, the stepper motor is installed on the rear side of the rear mounting plate, the output end of the front side of the stepper motor passes through the rear mounting plate and is fixedly connected to the rear side of the connecting shaft, the threaded sleeve is threadedly connected to the surface of the lead screw, the slider is slidably connected to the surface of the limit rod, and the PLC controller is installed on the left front side of the top of the vulcanizing machine body.

[0008] Preferably, the connecting mechanism includes a movable plate, a connecting screw hole, a lower mold, a connecting block, and a connecting screw, wherein the movable plate is welded to the top of the threaded sleeve and the slider, respectively.

[0009] Preferably, the connecting screw holes are respectively opened on the inner side of the movable plate and the inner side of the connecting block, and the lower mold is movably connected to the inner side of the movable plate.

[0010] Preferably, the connecting block is welded to the chamfer of the lower mold surface, and the connecting screw is threaded into the inner side of the connecting screw hole.

[0011] Preferably, a buffer pad is fixedly connected to the rear side of the front mounting plate and the front side of the rear mounting plate, and the buffer pad is made of silicone material.

[0012] Preferably, the bottom of the movable plate is welded with reinforcing ribs, and the surface of the reinforcing ribs is coated with an anti-corrosion coating.

[0013] Preferably, an emergency stop button is installed on the right side of the vulcanizing machine body, and the emergency stop button is electrically connected to the PLC controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The conveying mechanism of this application replaces the traditional manual handling of molds through the coordinated action of a stepper motor, lead screw, threaded sleeve and slider. The stepper motor drives the connecting shaft to rotate the lead screw, so that the threaded sleeve moves smoothly along the surface of the lead screw. At the same time, the slider slides synchronously along the limit rod, thereby driving the top connecting mechanism and the lower mold to move. The lower mold containing the material can be conveyed to the vulcanization area of ​​the vulcanizing machine body. After vulcanization, the mold can be automatically transferred to the demolding station. The entire conveying process does not require manual intervention, avoiding the tediousness and time-consuming manual handling, solving the problem of waiting for materials and stopping the traditional vulcanizing machine due to manual conveying, significantly improving the overall production efficiency and adapting to the needs of large-scale production.

[0016] 2. The connecting mechanism of this application achieves reliable fixation between the lower mold and the moving plate through the cooperation of the connecting block, connecting screw, and connecting screw hole. The connecting block welded at the chamfer of the lower mold surface has its inner connecting screw hole aligned with the inner screw hole of the moving plate. The lower mold can be firmly fixed to the inside of the moving plate by the threaded connection of the connecting screw. This can prevent the mold from shaking or shifting during transportation or vulcanization, prevent material spillage or vulcanization deviation, and provide a basic guarantee for the stable operation of the vulcanization process. When it is necessary to change the lower mold of different specifications to produce different rubber and plastic products, simply unscrew the connecting screw to remove the old mold from the moving plate, then align the connecting block of the new mold with the screw hole of the moving plate and tighten the connecting screw to complete the mold change operation. The entire disassembly and assembly process does not require complicated tools, the steps are simple and quick, greatly shortening the mold change time and reducing equipment downtime. At the same time, the convenient disassembly and assembly method also facilitates the cleaning, maintenance or repair of the lower mold, reducing equipment maintenance costs.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A vulcanizing device for processing rubber and plastic products includes a vulcanizing machine body 1. Conveying mechanisms 2 are welded to both sides of the top of the vulcanizing machine body 1. A connecting mechanism 3 is welded to the top of the conveying mechanism 2. The conveying mechanism 2 includes a mounting plate 21, two limiting rods 22, a lead screw 23, a stepper motor 24, a threaded sleeve 25, a slider 26, and a PLC controller 27. The mounting plate 21 is welded to the front and rear sides of the top of the vulcanizing machine body 1, respectively. The limiting rods 22 are welded to both sides of the front side of the rear mounting plate 21, and the front side of the limiting rods 22 is welded to the rear side of the front mounting plate 21. The lead screw 23 is rotatably connected to the front side of the rear mounting plate 21 and the rear side of the front mounting plate 21. A connecting shaft is connected to the rear side of the lead screw 23 via a flat key.

[0026] In this embodiment: the vulcanizing machine body 1 provides a sturdy mounting carrier for the top-welded conveying mechanism 2 and connecting mechanism 3, and can also provide suitable vulcanization conditions such as temperature and pressure for rubber and plastic products through its own vulcanization function. The mounting plate 21 provides a sturdy mounting base for the limiting rod 22 and the lead screw 23. The limiting rod 22 provides guidance for the slider 26 to ensure conveying accuracy. The lead screw 23 is threadedly connected to the threaded sleeve 25. When the stepper motor 24 drives the lead screw 23 to rotate, the threaded sleeve 25 will move at a constant speed along the surface of the lead screw 23, thereby driving the moving plate 31 and the mold to move synchronously. The stepper motor 24 can be speed-adjusted and fixed by the PLC controller 27. The PLC controller 27 can adjust the output speed according to the vulcanization process requirements, control the rotation speed of the lead screw 23, and thus adjust the mold conveying speed. The threaded sleeve 25 converts the rotational motion of the lead screw 23 into linear motion, realizing the translational conveying of the mold. The slider 26 assists the threaded sleeve 25 in driving the moving plate 31 to move smoothly, improving the conveying stability. The PLC controller 27 can preset instructions such as conveying speed and vulcanization parameters, and control the operating status of components such as the stepper motor 24 and the vulcanizing machine body 1 to realize the automated linkage of mold conveying and vulcanization operations. At the same time, it can receive signals from components such as the emergency stop button 6, and respond quickly in case of emergencies to control the equipment to stop operation and ensure operational safety.

[0027] Specifically, such as Figure 2 , Figure 3 As shown, the stepper motor 24 is installed on the rear side of the rear mounting plate 21. The output end of the stepper motor 24 passes through the rear mounting plate 21 and is fixedly connected to the rear side of the connecting shaft. The threaded sleeve 25 is threadedly connected to the surface of the lead screw 23. The slider 26 is slidably connected to the surface of the limit rod 22. The PLC controller 27 is installed on the left front side of the top of the vulcanizing machine body 1.

[0028] Specifically, such as Figure 4 As shown, the connecting mechanism 3 includes a movable plate 31, a connecting screw hole 32, a lower mold 33, a connecting block 34, and a connecting screw 35. The movable plate 31 is welded to the top of the threaded sleeve 25 and the slider 26, respectively.

[0029] Specifically, such as Figure 4 As shown, the connecting screw holes 32 are respectively opened on the inner side of the movable plate 31 and the inner side of the connecting block 34, and the lower mold 33 is movably connected to the inner side of the movable plate 31.

[0030] In this embodiment: the movable plate 31 provides a platform for placing and fixing the lower mold 33, ensuring that the mold can move synchronously with the conveying mechanism 2, and integrates the linear motion of the threaded sleeve 25 with the guiding effect of the slider 26, driving the mold to move smoothly. The connecting screw hole 32 provides an installation channel for the connecting screw 35, realizing the detachable fixing of the lower mold 33 and the movable plate 31. The lower mold 33 provides molding space for rubber and plastic materials, ensuring the product shape accuracy. The connecting block 34 provides a force carrier for the connection between the lower mold 33 and the movable plate 31, enhancing the fixing stability. The connecting screw 35 takes into account both connection reliability and ease of disassembly and assembly. By rotating the connecting screw 35, the connecting block 34 and the movable plate 31 can be tightly locked, ensuring that the mold has no displacement during conveying and vulcanization, ensuring molding accuracy. When it is necessary to replace the mold, it can be disassembled simply by rotating the screw in the opposite direction. The operation is simple and quick, without complicated tools, greatly shortening the mold change time.

[0031] Specifically, such as Figure 4 As shown, the connecting block 34 is welded to the chamfer of the surface of the lower mold 33, and the connecting screw 35 is threaded into the inner side of the connecting screw hole 32.

[0032] Specifically, such as Figure 5 As shown, buffer pads 4 are fixedly connected to the rear side of the front mounting plate 21 and the front side of the rear mounting plate 21. The buffer pads 4 are made of silicone material.

[0033] In this embodiment: by setting the buffer pad 4, the collision force between the component and the mounting plate 21 can be absorbed, avoiding direct impact of metal components causing wear or deformation, and extending the service life of components such as the mounting plate 21 and the threaded sleeve 25. By setting the buffer pad 4 to be made of silicone material, the silicone material has good elasticity and sound insulation effect, which can reduce the noise generated by the collision and improve the working environment.

[0034] Specifically, such as Figure 3 As shown, a reinforcing rib 5 is welded to the bottom of the movable plate 31, and the surface of the reinforcing rib 5 is coated with an anti-corrosion coating.

[0035] Specifically, such as Figure 5 As shown, an emergency stop button 6 is installed on the right side of the vulcanizing machine body 1, and the emergency stop button 6 is electrically connected to the PLC controller 27.

[0036] In this embodiment: by setting reinforcing ribs 5, the structural strength of the moving plate 31 is enhanced, and its service life is extended. By setting anti-corrosion coating, it can resist corrosive gases, oil stains, etc. that may be generated during the vulcanization process, preventing the reinforcing ribs 5 from rusting and being damaged, and further extending its service life. By setting an emergency stop button 6, when an emergency occurs during equipment operation, such as mold displacement, component failure, or personnel misoperation, the operator can quickly press the emergency stop button 6. The button transmits a signal to the PLC controller 27, and the controller immediately controls all operating components such as the stepper motor 24 and the vulcanizing machine body 1 to stop working, so as to avoid the accident from escalating and protect the safety of the equipment and the operator.

[0037] Working principle: First, the operator places the lower mold 33 inside the moving plate 31, aligning the connecting screw hole 32 on the connecting block 34 with the connecting screw hole 32 inside the moving plate 31. Then, the connecting screw 35 is screwed into the aligned connecting screw hole 32, thus firmly fixing the lower mold 33 to the moving plate 31. Next, the rubber and plastic material to be vulcanized is placed into the fixed lower mold 33. Simultaneously, the parameters such as mold conveying speed, vulcanization temperature, and vulcanization time are preset through the PLC controller 27 on the top left front side of the vulcanizing machine body 1, preparing for subsequent operations. After preparation, the operator sends a start command through the PLC controller 27. The PLC controller 27 immediately sends a signal to the stepper motor 24. After the stepper motor 24 starts, its front output end drives the lead screw 23 to rotate through the connecting shaft. Since the threaded sleeve 25 is threadedly connected to the surface of the lead screw 23, and the moving plate 31 is welded to the top of the threaded sleeve 25 and the slider 26 respectively, and the slider 26 is slidably connected to the surface of the limit rod 22, when the lead screw 23 rotates, the threaded sleeve 25 will move forward at a constant speed along the surface of the lead screw 23, while the slider 26 moves forward at a constant speed along the limit rod 22. 2. Synchronous sliding, together driving the top moving plate 31 and the lower mold 33 fixed on the moving plate 31 to move smoothly towards the vulcanizing position of the vulcanizing machine body 1. Then, after the lower mold 33 moves to the vulcanizing position, the PLC controller 27 controls the stepper motor 24 to stop working. At this time, the vulcanizing machine body 1 starts, and through its own functions, provides the preset temperature, pressure and other vulcanizing conditions for the rubber and plastic material in the lower mold 33, and begins the vulcanization operation of the rubber and plastic products. Finally, when the vulcanization time reaches the preset value, the PLC controller 27 controls the vulcanizing machine body to... 1. Stop the vulcanization operation and restart the stepper motor 24 to make it rotate in reverse, which will drive the lead screw 23 to rotate in reverse. This will cause the threaded sleeve 25 and the slider 26 to move the moving plate 31 and the vulcanized lower mold 33 to the demolding station. After the mold moves to the designated position, the stepper motor 24 stops working. The operator unscrews the connecting screw 35 and removes the lower mold 33 from the moving plate 31. The vulcanized rubber and plastic products inside are taken out. After cleaning the lower mold 33, the above steps can be repeated for the vulcanization operation of the next batch of rubber and plastic products.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
