Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, specifically a cooling device for the production of precipitated silicone rubber. Background Technology

[0002] Precipitated silicone rubber, as an important rubber material, has wide applications in many fields such as electronics, medical, and construction. It is produced through a specific chemical precipitation process. During the production process, the freshly formed silicone rubber is at a high temperature and requires effective cooling treatment to achieve suitable hardness, elasticity, and other performance indicators to meet the needs of different application scenarios.

[0003] A search revealed Chinese patent application number 202121397857.3, which discloses a cooling device for rubber production. The device includes a cooling water tank. A guide frame is fixedly installed on the upper surface of the cooling water tank. An adjusting frame, a high mounting frame, and a low mounting frame are fixedly installed on the inner bottom wall of the cooling water tank. Guide rollers are rotatably connected to the inner walls of the guide frame, high mounting frame, and low mounting frame via bearings. A rotating shaft is rotatably connected to the inner wall of the adjusting frame via bearings. A rotating drum and a baffle ring are fixedly installed on the surface of the rotating shaft. A baffle plate is fixedly installed on the surface of the baffle ring. An adjusting groove is formed on the inner wall of the adjusting frame. This cooling device for rubber production utilizes the adjusting rollers to clamp the rubber strip onto the surface of the rotating drum. As the rubber strip moves, it drives the rotating shaft to rotate, which in turn drives the baffle ring to rotate. This causes the baffle plate to agitate the water in the cooling water tank, accelerating the flow of water and making the water temperature in the cooling water tank more uniform, thus improving the cooling efficiency of the rubber strip.

[0004] Although the aforementioned patent utilizes an adjusting roller to clamp the rubber belt onto the surface of the rotating drum, and the rubber belt, during its movement, drives the rotating shaft to rotate, which in turn drives the turbulence ring to rotate, causing the turbulence plate to agitate the water in the cooling water tank, accelerating the flow of water in the cooling water tank, making the water temperature in the cooling water tank more uniform, and improving the efficiency of cooling the silicone rubber; however, in actual use, the silicone rubber is directly transferred out of the device after being cooled by the cooling water, which easily causes the cooling water to drip around the equipment, resulting in rapid loss of cooling water in the water tank and requiring frequent replenishment, affecting the working environment and cooling effect. At the same time, the cooling water adhering to the surface of the rubber strip affects subsequent production operations, causing inconvenience to the user.

[0005] Therefore, it is necessary to modify it by setting up a conveyor to guide the silicone rubber after cooling, so that the residual cooling water on the surface of the silicone rubber flows back into the cooling water tank, avoiding splashing of cooling water, and air-drying the surface to facilitate subsequent production operations of silicone rubber. Utility Model Content

This device guides the cooled silicone rubber through a conveyor frame, allowing residual cooling water on the surface to flow back into the cooling water tank, preventing splashing and allowing the surface to be air-dried. This facilitates subsequent production operations. It solves the problems of directly transferring the cooled silicone rubber out of the device, which easily leads to cooling water dripping around the equipment, causing rapid loss of cooling water in the tank and requiring frequent replenishment, affecting the working environment and cooling effect. Furthermore, the presence of cooling water adhering to the rubber strip surface affects subsequent production operations, causing inconvenience to the user.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for the production of precipitated silicone rubber, comprising a cooling water tank, an adjusting frame fixedly connected to the left side inside the cooling water tank, a fixed roller rotatably connected to the lower part inside the adjusting frame, several evenly distributed baffles fixedly connected to the front and rear sides of the surface of the fixed roller, a circular groove opened at the top of the adjusting frame, and a rust-proof nut seat fixedly connected inside the circular groove, a rust-proof bolt threaded inside the rust-proof nut seat, and a movable plate located inside the adjusting frame rotatably connected to the bottom of the rust-proof bolt. The bottom of the moving plate is rotatably connected to an adjusting roller that works with the fixed roller. Three guide rollers arranged in an alternating pattern are rotatably connected to the right side inside the cooling water tank. An upwardly inclined conveyor frame is fixedly connected to the upper right side of the cooling water tank.

Drying fans are fixedly connected to both the front and rear sides of the right side of the inner wall of the cover.

[0008] As a preferred embodiment of this utility model, air inlet slots are provided on both the front and rear sides of the right side of the cover, and protective frames located on the surface of the air inlet slots are fixedly connected to both the front and rear sides of the right side of the cover, with protective nets fixedly connected inside the protective frames.

[0009] As a preferred embodiment of this utility model, heat dissipation plates are fixedly connected to both the front and rear sides of the inner wall of the cooling water tank, and a number of evenly distributed heat dissipation fins are fixedly connected to the outer side of the heat dissipation plates. The end of the heat dissipation fins away from the heat dissipation plates extends through to the outside of the cooling water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the combination of a fixed roller and a baffle plate within the adjusting frame, allows the baffle plate to agitate the water in the cooling water tank when the silicone rubber moves and drives the fixed roller to rotate, resulting in a more uniform water temperature and improved cooling effect. The adjusting roller can adjust its distance from the fixed roller using rust-proof bolts and rust-proof nut seats to accommodate the cooling needs of silicone rubber of different thicknesses. Three staggered guide rollers can alter the movement path of the silicone rubber, extending its residence time in the cooling water and enhancing the cooling effect. The conveyor frame guides the cooled silicone rubber, and the first and second scraper strips remove most of the cooling water from the surface of the silicone rubber, allowing it to flow back into the cooling water tank, reducing cooling water loss and splashing.

[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides a cooling device for the production of precipitated silicone rubber, including a cooling water tank 1. An adjusting frame 2 is fixedly connected to the left side inside the cooling water tank 1. A fixed roller 3 is rotatably connected to the lower part of the adjusting frame 2. Several evenly distributed baffles 4 are fixedly connected to the front and rear sides of the surface of the fixed roller 3. A circular groove is formed at the top of the adjusting frame 2, and a rust-proof nut seat 5 is fixedly connected inside the groove. A rust-proof bolt 6 is threaded inside the rust-proof bolt 6. A movable plate 7 located inside the adjusting frame 2 is rotatably connected to the bottom of the rust-proof bolt 6. An adjusting roller 8, which works with the fixed roller 3, is rotatably connected to the bottom of the movable plate 7 via a connecting rod. Three guide rollers 9, arranged vertically and horizontally, are rotatably connected to the right side inside the cooling water tank 1 via a rotating shaft. An upwardly inclined conveyor frame 10 is fixedly connected to the upper side. A detachable first wiper strip 11 is fixedly connected to the left side of the bottom of the inner wall of the conveyor frame 10. A strip plate 12 is provided on the left side of the top of the conveyor frame 10. A detachable second wiper strip 13, which works in conjunction with the first wiper strip 11, is fixedly connected to the bottom of the strip plate 12. A cover 14 is fixedly connected to the right side of the top of the conveyor frame 10. A drying fan 15 is fixedly connected to both the front and rear sides of the right side of the inner wall of the cover 14. The output end of the drying fan 15 faces to the left. A guide roller (not shown) is provided on the left side of the top of the cooling water tank 1. The guide roller allows the silicone rubber to enter the cooling water tank 1 smoothly. A drain valve pipe is connected to the bottom right side of the front of the cooling water tank 1. The drain valve pipe facilitates the replacement or drainage of water in the cooling water tank 1.

[0023] refer to Figure 4Air inlet slots are provided on both the front and rear sides of the right side of the cover 14. Protective frames 16 located on the surface of the air inlet slots are fixedly connected to both the front and rear sides of the right side of the cover 14 by bolts. Protective nets are fixedly connected inside the protective frames 16.

[0024] As a technical optimization of this utility model, the air intake slot on the right side of the cover 14 provides a sufficient air intake channel for the drying fan 15, ensuring that the drying fan 15 can operate normally and generate enough wind to dry the moisture on the silicone rubber surface. The protective frame 16 and the protective net can prevent external debris, dust and other objects from entering the interior of the cover 14 through the air intake slot, avoiding damage to the drying fan 15 or affecting its normal operation, extending the service life of the drying fan 15, and also ensuring the stability of the drying effect.

[0025] refer to Figure 1 A heat spreader plate 17 is fixedly connected to both the front and rear sides of the inner wall of the cooling water tank 1. Several evenly distributed heat dissipation fins 18 are fixedly connected to the outer side of the heat spreader plate 17. The end of the heat dissipation fin 18 away from the heat spreader plate 17 extends through to the outside of the cooling water tank 1.

[0026] As a technical optimization of this utility model, the heat dissipation plate 17 installed on the inner wall of the cooling water tank 1 can distribute the heat in the cooling water tank 1 more evenly and avoid excessive local temperature. The heat dissipation fins 18 are fixed on the outside of the heat dissipation plate 17 and extend to the outside of the cooling water tank 1, which can increase the heat dissipation area, accelerate the heat dissipation to the external environment, effectively reduce the water temperature in the cooling water tank 1, maintain the stability of the water temperature in the cooling water tank 1, thereby ensuring the cooling effect on the precipitated silicone rubber and improving the cooling efficiency and quality.

[0027] refer to Figure 1 Heat-resistant sealing strips 19 are fixedly connected to the four sides of the inner end surface of the heat dissipation fins 18. The surface of the heat-resistant sealing strips 19 is fixedly connected to the surface of the cooling water tank 1. Several evenly distributed heat dissipation holes 20 are opened on the surface of the heat dissipation fins 18.

[0028] As a technical optimization of this utility model, by setting a heat-resistant sealing strip 19 around the inner end surface of the heat dissipation fin 18, water in the cooling water tank 1 can be prevented from leaking from the connection between the heat dissipation fin 18 and the cooling water tank 1, thus ensuring the sealing and normal operation of the cooling water tank 1. The heat dissipation holes 20 opened on the surface of the heat dissipation fin 18 further increase the heat dissipation area, allowing heat to dissipate more quickly, improving heat dissipation efficiency, helping to maintain a low temperature environment in the cooling water tank 1, and ensuring the cooling quality of the precipitated silicone rubber.

[0029] refer to Figure 1The front and rear sides of the top of the adjustment frame 2 are provided with round holes, and a sliding sleeve 21 is fixedly connected inside the round hole. A slidable stabilizer 22 is slidably connected inside the sliding sleeve 21, and the bottom end of the slid stabilizer 22 is fixedly connected to the top of the moving plate 7.

[0030] As a technical optimization of this utility model, by setting the sliding sleeve 21 and the stabilizing rod 22 on the top of the adjusting frame 2 to cooperate, the stability of the moving plate 7 during the up and down movement can be guaranteed; when the position of the moving plate 7 is adjusted by the anti-rust bolt 6, the stabilizing rod 22 slides in the sliding sleeve 21 to prevent the moving plate 7 from shaking or shifting, ensuring that the adjusting roller 8 can accurately cooperate with the fixed roller 3, realizing effective cooling of silicone rubber of different thicknesses, and improving the adjustment accuracy and reliability of the device.

[0031] refer to Figure 1 Both ends of the strip 12 are provided with through holes, and a guide rod 23 is slidably connected inside the through holes. The bottom end of the guide rod 23 is fixedly connected to the surface of the conveyor frame 10 through a support plate. A compression spring 24 is sleeved on the surface of the guide rod 23. The top end of the compression spring 24 is fixedly connected to the top end of the guide rod 23, and the bottom end of the compression spring 24 is fixedly connected to the bottom of the strip 12.

[0032] As a technical optimization of this utility model, by setting the guide rod 23 and the compression spring 24 on the strip 12 to cooperate, the strip 12 can slide up and down on the guide rod 23. The elastic force of the compression spring 24 can make the second wiper strip 13 fit tightly against the first wiper strip 11, thereby enhancing the wiping effect on the cooling water of the silicone rubber surface. At the same time, this adjustable structure can adapt to the slight changes in the thickness of the silicone rubber, ensuring the stability of the wiping effect, further reducing the residual moisture on the surface of the silicone rubber, and providing convenience for subsequent production operations.

[0033] The working principle and usage process of this utility model are as follows: During use, check if the water level in the cooling water tank 1 is appropriate. If the water level is too low, add cooling water. Based on the thickness of the silicone rubber to be cooled, rotate the anti-rust bolt 6 to adjust the distance between the adjusting roller 8 and the fixed roller 3, ensuring the silicone rubber can pass smoothly and achieve a good cooling effect. The newly formed high-temperature precipitated silicone rubber is introduced into the cooling water tank 1 through the guide roller. The silicone rubber passes sequentially between the fixed roller 3 and the adjusting roller 8, and then through the guide roller 9 within the cooling water tank 1, with the head end of the silicone rubber passing through the first scraper strip 11 and the second… Between the two scraper strips 13, the silicone rubber passes through the right end of the conveyor frame 10 and connects to the external traction mechanism. The external traction mechanism drives the silicone rubber to move to the right. During this process, the baffle 4 on the fixed roller 3 continuously stirs the cooling water to ensure uniform water temperature. After cooling, the silicone rubber enters the conveyor frame 10. The first scraper strip 11 and the second scraper strip 13 scrape off most of the cooling water on its surface. The silicone rubber continues to move forward into the cover 14. The drying fan 15 dries the residual moisture on its surface. After scraping and drying, the silicone rubber can directly enter the subsequent production process.
