[0002] Acid and alkali resistant EPDM rubber is a synthetic rubber with excellent resistance to acid and alkali corrosion, good aging resistance, and elasticity. It is widely used in chemical, pharmaceutical, and water treatment industries where high corrosion resistance is required. The tableting process of acid and alkali resistant EPDM rubber requires an acid and alkali resistant EPDM rubber tableting machine. This machine, through the use of appropriate tableting components and rotating rollers, compresses and stretches the acid and alkali resistant EPDM rubber raw material, processing it into sheets of a certain thickness and shape to meet the needs of subsequent production. It is one of the key pieces of equipment in the production process of acid and alkali resistant EPDM rubber products. Existing acid and alkali resistant EPDM rubber tableting machines typically lack auxiliary feeding and positioning mechanisms, which makes it easy for rubber raw materials to deviate, wrinkle, and accumulate when entering the tableting assembly. This not only affects tableting efficiency but may also lead to material waste. Summary of the Invention

[0003] The purpose of this invention is to provide an acid and alkali resistant EPDM rubber processing and pressing machine to solve the problems mentioned in the background art.

One side of the support assembly is provided with an intermittent conveying assembly for intermittently conveying the rubber block. One side of the support assembly is provided with a pressing assembly for squeezing out excess water inside the rubber block. The side of the support assembly near the pressing assembly is provided with a storage frame for storing the compressed rubber sheet.

[0005] As a preferred embodiment of the above technical solution, the support assembly includes a base plate, and four legs are fixedly connected in a rectangular arrangement in the upper middle region of the base plate, with a support platform fixedly connected to the upper end of the four legs.

[0006] As a preferred embodiment of the above technical solution, the intermittent conveying assembly includes a first fixed block and a second fixed block. The first fixed block is fixedly connected to the center of one side of the support platform away from the end of the tablet pressing assembly. The second fixed block is fixedly connected to one side of the support platform near one end. A rotating shaft is rotatably connected to the center of the first fixed block. A movable disk is fixedly connected to the upper end of the rotating shaft. Four rotating rods are fixedly connected in a ring on the outer side of the movable disk.

[0007] As a preferred embodiment of the above technical solution, a ratchet disk is fixedly connected to the lower end of the rotating shaft, a fixing plate is fixedly connected to the side of the base plate near the first fixing block, a pawl is rotatably connected to the side of the fixing plate away from the base plate, the pawl is adapted to the notch of the ratchet disk, and a camshaft is fixedly connected to the center of the side of the pawl near the ratchet disk.

[0008] As a preferred embodiment of the above technical solution, a first motor is fixedly connected to the upper end of the second fixing block, a rotating disk is fixedly connected to the output shaft of the first motor, an adapter block is fixedly connected to the end of the rotating disk near the pawl, the adapter block is in rolling contact with the outer wall of the camshaft, a connecting block is fixedly connected to the lower center of the support platform near the pawl and the upper center of the pawl near the pawl, and a traction spring is fixedly connected between the two connecting blocks.

[0009] As a preferred embodiment of the above technical solution, the tablet pressing assembly includes two fixed columns, which are fixedly connected to the upper part of the base plate at the center of one end near both sides.

The ends of the two rotating columns near the two second motors are respectively fixedly connected to the rotating ends of the two second motors. Rotating rollers are fixedly sleeved on the outer sides of the two rotating columns.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves the intermittent conveying function of rubber blocks by setting an intermittent conveying component. The intermittent conveying method allows the rubber blocks to enter the tableting stage in an orderly manner according to a preset time interval, avoiding problems such as rubber block accumulation and overlap that may be caused by continuous conveying. This ensures that each piece of rubber can be fully and uniformly processed, improving the consistency and stability of tableting.

[0011] 2. The main function of this utility model pressing assembly is to squeeze out excess water from the rubber block. When processing acid and alkali resistant EPDM rubber, removing excess water is a key step in improving the rubber's performance.

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-4 As shown, this utility model provides a technical solution: an acid and alkali resistant EPDM rubber processing and pressing machine, including a support component 1 and a rubber block 3. One side of the support component 1 is provided with an intermittent conveying component 2 for intermittently conveying the rubber block 3. One side of the support component 1 is provided with a pressing component 4 for squeezing out excess water inside the rubber block 3. The side of the support component 1 near the pressing component 4 is provided with a storage frame 5 for storing the compressed rubber sheet.

[0016] Support component 1 serves as the basic frame of the equipment, providing a stable load-bearing foundation for the entire processing flow and ensuring the stability of processing operations. Intermittent conveying component 2 enables the orderly intermittent conveying of rubber blocks 3, avoiding problems such as stacking and misalignment that occur due to continuous conveying of rubber blocks 3. This creates favorable conditions for the uniform processing of subsequent pressing component 4, effectively improving processing consistency. Pressing component 4 extrudes excess moisture from rubber blocks 3. For acid and alkali resistant EPDM rubber, the removal of excess moisture is directly related to the stability of its physical properties and corrosion resistance. This component, through precise extrusion, can efficiently separate excess moisture and ensure uniform thickness of the rubber sheet, laying the foundation for high-quality production of rubber products. Storage box 5 is used to centrally store processed rubber sheets, achieving orderly storage of finished products. This not only avoids problems such as contamination and deformation caused by random placement of rubber sheets after processing, but also facilitates subsequent retrieval and circulation, effectively improving production efficiency.

[0017] As one implementation method in this embodiment, please refer to Figure 2As shown, the support assembly 1 includes a base plate 101. Four legs 102 are fixedly connected in a rectangular arrangement in the upper middle region of the base plate 101. A support platform 103 is fixedly connected to the upper end of the four legs 102.

[0018] The base plate 101 is the foundation of the support assembly 1. By distributing the overall weight of the equipment through a large contact area, it prevents the equipment from shaking or shifting due to an unstable center of gravity during operation, providing a stable bottom support for the entire equipment. The four support legs 102 are symmetrically distributed to evenly distribute the weight of the support platform 103 and the components above, further enhancing the stability of the support structure. The support platform 103 serves as a platform for carrying intermittent conveying assembly 2, pressing assembly 4 and other working parts, providing a reliable operating foundation for the conveying, pressing and other processing of rubber blocks 3.

[0019] As one implementation method in this embodiment, please refer to Figure 3 As shown, the intermittent conveying assembly 2 includes a first fixed block 201 and a second fixed block 202. The first fixed block 201 is fixedly connected to the center of one side of the support platform 103 away from the end of the pressing assembly 4. The second fixed block 202 is fixedly connected to one side of the support platform 103 near one end. A rotating shaft 203 is rotatably connected to the center of the inside of the first fixed block 201. A movable disk 204 is fixedly connected to the upper end of the rotating shaft 203. Four rotating rods 205 are fixedly connected to the outer side of the movable disk 204 in a ring arrangement.

[0020] The first fixed block 201 and the second fixed block 202 provide stable support and positioning for the entire intermittent conveying assembly 2. The rotation of the rotating shaft 203 provides a power transmission path for the movement of the movable disk 204. The movable disk 204 rotates synchronously through its own rotation, which is the power transmission hub for realizing the intermittent conveying action. The movable disk 204 rotates with the rotation of the rotating shaft 203. As the mounting carrier for the rotating rods 205, the rotation of the movable disk 204 directly drives the four rotating rods 205 to make circular motion, thereby pushing the rubber block 3 to be conveyed. The four rotating rods 205 can contact the rubber block 3 in sequence and push it to move, forming an intermittent conveying rhythm. The setting of the four rotating rods 205 not only ensures the continuity of the conveying, but also realizes the orderly pushing of the rubber block 3 through the interval distribution, avoiding congestion or missed delivery in the conveying process, and providing a stable raw material supply for the subsequent processing of the tablet assembly 4. As one implementation method in this embodiment, please refer to Figure 3 As shown, a ratchet disk 206 is fixedly connected to the lower end of the rotating shaft 203, a fixing plate 209 is fixedly connected to the side of the base plate 101 near the first fixing block 201, a pawl 207 is rotatably connected to the side of the fixing plate 209 away from the base plate 101, the pawl 207 is adapted to the notch of the ratchet disk 206, and a camshaft 208 is fixedly connected to the center of the side of the pawl 207 near the ratchet disk 206.

[0021] The notch on the edge of the ratchet disc 206 is adapted to the pawl 207. When the pawl 207 engages with the notch of the ratchet disc 206, it drives the ratchet disc 206 to rotate. When the pawl 207 disengages from the notch, the ratchet disc 206 stops rotating, thus creating an intermittent rotation effect. The pawl 207 controls the rotation and stop of the rotating shaft 203 by engaging and disengaging with the ratchet disc 206, thereby determining the motion state of the movable disc 204 and the rotating rod 205. The rotation of the camshaft 208 can drive the pawl 207 to reciprocate, allowing the pawl 207 to periodically engage or disengage with the notch of the ratchet disc 206, providing power and trajectory guidance for the movement of the pawl 207. The fixed plate 209 provides a stable support point for the pawl 207, ensuring that the pawl 207 can rotate flexibly while limiting its range of motion, ensuring that the pawl 207 can accurately engage with the notch of the ratchet disc 206, and ensuring the stable operation of the entire intermittent transmission mechanism.

[0022] As one implementation method in this embodiment, please refer to Figure 3 As shown, the upper end of the second fixed block 202 is fixedly connected to the first motor 2010, the output shaft of the first motor 2010 is fixedly connected to the rotating disk 2011, the end of the rotating disk 2011 near the pawl 207 is fixedly connected to the adapter block 2012, the adapter block 2012 is in rolling contact with the outer wall of the camshaft 208, the lower center of the support platform 103 near the pawl 207 and the upper center of the pawl 207 are both fixedly connected to the connecting block 2013, and a traction spring 2014 is fixedly connected between the two connecting blocks 2013.

[0023] The rotation of the output shaft of the first motor 2010 provides continuous power for the movement of subsequent components. By driving the rotating disk 2011 to rotate, electrical energy is converted into mechanical energy. The rotating disk 2011 rotates synchronously with the output shaft, driving the adapter block 2012 to perform circular motion. This converts the continuous rotation of the first motor 2010 into periodic position changes of the adapter block 2012, providing the motion basis for the engagement between the adapter block 2012 and the camshaft 208. The adapter block 2012 maintains rolling contact with the outer wall of the camshaft 208. When the adapter block 2012 rotates to different positions of contact with the camshaft 208, it generates different thrusts on the camshaft 208, thereby driving the pawl 207 to swing, realizing the engagement and disengagement of the pawl 207 with the ratchet disc 206. The pawl 207 is a key component for transmitting power and controlling its movement. The connecting block 2013 and the traction spring 2014 are respectively fixed at the lower center of the support platform 103 and the upper center of the pawl 207. The traction spring 2014 connects between them. When the adapter block 2012 pushes the pawl 207 to swing away from the ratchet disc 206, the traction spring 2014 is stretched and stores elastic potential energy. When the adapter block 2012 rotates until it no longer applies a thrust to the camshaft 208, the elastic potential energy of the traction spring 2014 is released, pulling the pawl 207 back to its original position, allowing it to re-fit with the notch of the ratchet disc 206. This ensures the continuity and accuracy of the pawl 207's movement and guarantees the stable cycle of the intermittent transmission mechanism.

[0024] As one implementation method in this embodiment, please refer to Figure 4 As shown, the tablet compression assembly 4 includes two fixed columns 401. The two fixed columns 401 are fixedly connected to the upper center of the base plate 101 near both sides. A second motor 402 is fixedly connected to the center of one side of one of the fixed columns 401 near both the upper and lower ends. A rotating column 403 is rotatably sleeved inside the two fixed columns 401 near the upper and lower ends through bearings. The two rotating columns 403 are fixedly connected to the rotating ends of the two second motors 402 near their respective ends. A rotating roller 404 is fixedly sleeved on the outer side of the two rotating columns 403.

[0025] Two fixed columns 401 provide stable rotational support for the rotating column 403. Two second motors 402 can stably convert electrical energy into rotational power for the rotating column 403. The pressing speed of the rotating roller 404 can be flexibly controlled by adjusting the motor speed to adapt to the processing requirements of rubber sheets of different thicknesses. The rotating column 403 realizes the transmission of power from the second motor 402 to the rotating roller 404. Through its own rigid structure, it ensures that the rotating roller 404 will not deform when extruding the rubber block 3. The upper and lower sets of rotating rollers 404 rotate relative to each other under the drive of the motor. Through the extrusion action between the roller body and the rubber block 3, the excess water inside the rubber block 3 is squeezed out, and the rubber block 3 is extended into a sheet of the preset thickness. The double-layer design not only improves the dehydration efficiency of a single pressing, but also reduces the wrinkles and displacement of the rubber sheet through the synchronous extrusion of the upper and lower rollers, ensuring the flatness and thickness consistency of the finished sheet.

[0026] Working principle: Rubber block 3 falls on the inclined support platform 103 under the action of gravity. Two rotating columns 403 block rubber block 3. At the same time, the first motor 2010 drives the rotating disk 2011 and the adapter block 2012 to rotate. The adapter block 2012 pushes the pawl 207 to swing through the rolling contact with the camshaft 208, so that the pawl 207 engages with the ratchet disk 206 and drives the rotating shaft 203 to rotate. After the adapter block 2012 disengages, the traction spring 2014 pulls the pawl 207 to reset, allowing the rotating shaft 203 to rotate. The rotating shaft 203 rotates intermittently, and the movable disk 204 at the upper end of the rotating shaft 203 rotates synchronously with it. The rotating rod 205 on the movable disk 204 intermittently pushes the rubber block 3. The second motor 402 drives the rotating column 403 on the same side to rotate. The rotating column 403 drives the rotating roller 404 to rotate synchronously. The rotating column 403 on the other side rotates with the rotating roller 404. The upper and lower sets of rotating rollers 404 form a relative compression space. After the rubber block 3 enters, it is squeezed, dehydrated and pressed into a sheet. The rubber sheet is transported to the storage frame 5 as the rotating roller 404 rotates.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
