Description
Technical Field
[0001] This utility model relates to the field of rubber technology, specifically a preheating device for producing rubber sheets. Background Technology
[0002] Rubber sheets are sheet materials made of rubber, which have good elasticity and flexibility and can adapt to a variety of complex environments. Different types of rubber sheets, such as natural rubber sheets and synthetic rubber sheets, have their own advantages in terms of wear resistance, corrosion resistance, and high and low temperature resistance.
[0003] The production process of rubber sheets includes raw material preparation, plasticizing, mixing, molding, vulcanization, and post-treatment. During molding, the rubber sheets need to be preheated before being passed through the gap between the rollers of the calender to form a sheet of a certain thickness and width. This preheating reduces the viscosity of the rubber sheets, improves their plasticity and fluidity, and makes them easier to stretch and pass evenly through the gap between the rollers during calendering. This results in a sheet with uniform thickness and good surface quality, while also reducing equipment load and improving calendering efficiency.
[0004] Existing preheating devices for rubber sheets have limitations in heating range due to the different patterns on the bottom of the rubber sheets. This results in uneven heating of rubber sheets with different patterns, affecting the subsequent molding process of the rubber sheets.
[0005] Therefore, a preheating device for producing rubber sheets is proposed to address the above problems. Utility Model Content

[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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a preheating device for producing rubber sheets includes a processing box 1. The inner wall of the processing box 1 has an inlet groove 11 and an outlet groove 12. A first partition 13 is fixedly connected to the top inner side of the processing box 1. A second partition 14 is fixedly connected to the top inner side of the processing box 1. A support column 15 is fixedly connected to the top inner side of the processing box 1. A first fixing seat 16 is fixedly connected to the end of the support column 15. A third motor 103 is fixedly connected to the side wall of the first fixing seat 16. A first roller 104 is fixedly connected to the output end of the third motor 103. The inner wall of the first roller 104... Multiple heating elements 17 are fixedly connected; a second motor 102 is fixedly connected to the side wall of the first fixed base 16; a second roller 105 is fixedly connected to the output end of the second motor 102; a first motor 101 is fixedly connected to the outer wall of the processing box 1; a cylinder 18 is fixedly connected to the output end of the first motor 101; a metal conveyor belt 19 is sleeved on the outside of the cylinder 18; a rubber sheet is fed into the processing box 1 through the inlet groove 11 and then placed on the metal conveyor belt 19. At this time, the first motor 101 can be started, and then the first motor 101 will drive the cylinder 18 to start rotating. When the cylinder 18 rotates, the metal conveyor belt 19 will also rotate. The rollers are driven to rotate, and at this time, the heating elements 17 inside the first roller 104 and the second roller 105 can be activated simultaneously. The heating elements 17 will then heat the interiors of the first roller 104 and the second roller 105. Since the heating elements 17 inside the first roller 104 are not as high as those inside the second roller 105, the temperature inside the first roller 104 is lower than that inside the second roller 105. At this point, the second motor 102 and the third motor 103 can be activated to drive the second roller 105 and the first roller 104 to rotate respectively. The rubber sheet will then be transported on the metal conveyor belt 19, first passing through the first... The surface of the rubber sheet is first preheated by the first roller 104, and then it passes through the rotating second roller 105. When passing through the second roller 105, it will be heated significantly. Finally, the preheated rubber sheet can be transported to the outside of the processing box 1 through the outlet groove 12. By adding heating plate 17, the surface of the rubber sheet can be preheated. At the same time, by adding the first roller 104, the rubber sheet can be rolled by the first roller 104 regardless of its length and then uniformly heated. No matter what the texture of the rubber sheet surface is, it can be uniformly preheated by the first roller 104 and the second roller 105.
[0026] like Figures 1 to 3As shown, a spring telescopic rod 2 is fixedly connected to the top of the inner side of the processing box 1; a second fixed seat 21 is fixedly connected to the bottom of the spring telescopic rod 2; a rotating shaft 22 is fixedly connected to the inner wall of the second fixed seat 21; a roller 23 is sleeved on the outer wall of the rotating shaft 22; the roller 23 is rotatably connected to the outside of the spring telescopic rod 2; after the rubber sheet is preheated by the first roller 104 and the second roller 105, the metal conveyor belt 19 will drive the rubber sheet into the bottom of the second fixed seat 21. At this time, the spring telescopic rod 2 can be adjusted... The height is adjusted by the spring telescopic rod 2, which then drives the roller 23 to adjust the height together. When the roller 23 is adjusted to contact the rubber sheet, the spring telescopic rod 2 is released. At this time, the rubber sheet will be flattened in time after being preheated. By adding the spring telescopic rod 2, the position of the roller 23 can be adjusted, so that the rubber sheet, whether thick or thin, can be pressed. At the same time, adding the roller 23 can solve the problem of unevenness, wrinkles or bumps on the surface of the rubber sheet after heating, effectively ensuring the forming state of the rubber sheet.
[0027] like Figures 1 to 3 As shown, a base plate 31 is fixedly connected to the inner wall of the processing box 1; a sliding groove 34 is formed inside the base plate 31; a limiting seat 3 is provided inside the sliding groove 34; the limiting seat 3 is slidably connected inside the sliding groove 34; an insertion hole 32 is formed on the side wall of the base plate 31; a lead screw 33 is provided inside the insertion hole 32; the insertion hole 32 and the lead screw 33 are correspondingly arranged; after the rubber sheet enters the processing box 1 through the inlet groove 11, the rubber sheet is placed on the base plate 31, and then the lead screw 33 is inserted into the groove. Insert the socket 32 and start rotating the lead screw 33. The lead screw 33 will then press against the limit seat 3. As the lead screw 33 is rotated, the limit seat 3 will move further and further inward inside the slide 34. Stop rotating the lead screw 33 when the limit seat 3 contacts the rubber sheet. By adding the limit seat 3, the position of the rubber sheet can be limited, reducing the possibility of displacement deviation and falling outside the metal conveyor belt 19 during subsequent conveying. The limit seat 3 can effectively limit the rubber sheet.
[0028] like Figures 1 to 4 As shown, an air pump 41 is fixedly connected to the top of the processing box 1; an air blowing pipe 4 is fixedly connected to the end of the air pump 41; after the rubber sheet is limited by the limiting seat 3, the air pump 41 can be started at this time, and then the air pump 41 will inject air into the air blowing pipe 4, and then the air will flow out through the air blowing pipe 4 to the inside of the processing box 1 and the surface of the rubber sheet; by adding the air blowing pipe 4, the dust and debris on the surface of the rubber sheet can be removed during preheating, and the subsequent preheating and flattening can be handled better, increasing the subsequent better molding state of the rubber sheet.
[0029] like Figures 1 to 4As shown, a water tank 51 is fixedly connected to the bottom inner side of the processing box 1; a flexible water pipe 5 is provided on the side wall of the water tank 51; the flexible water pipe 5 is telescopic; a collar seat 52 is fixedly connected to the bottom inner side of the processing box 1; the collar seat 52 is sleeved on the outside of the flexible water pipe 5; after the first roller 104 and the second roller 105 have completed the preheating of the rubber sheet, water can be injected into the water tank 51, and then the flexible water pipe 5 can be removed from the collar seat 52, and the flexible water pipe 5 can be pulled to spray water mist onto the surface of the first roller 104 and the second roller 105; by adding the flexible water pipe 5, the surface of the first roller 104 and the second roller 105 can be cooled down in time after the rubber sheet has been preheated, so that it can enter a better state for the next use. At the same time, the flexible water pipe 5 can also cool down the temperature inside the processing box 1.
[0030] like Figure 2 and Figure 5 As shown, a pair of sponge blocks 6 are fixed to the inner wall of the outlet groove 12; the sponge blocks 6 and the outlet groove 12 are correspondingly arranged; when the rubber sheet exits from the inside of the outlet groove 12, the rubber sheet will come into contact with the sponge blocks 6 on the side wall of the outlet groove 12, and then the moisture and dust on the surface of the rubber sheet will be removed by the sponge blocks 6; by adding sponge blocks 6, the dust and impurities on the surface of the rubber sheet can be further removed, ensuring that the rubber sheet has a better molding state after preheating, and increasing the cleanliness of the surface of the rubber sheet.
[0031] Working principle: The rubber sheet is fed into the processing box 1 through the inlet groove 11 and then placed on the metal conveyor belt 19. At this time, the first motor 101 can be started, which will drive the cylinder 18 to rotate. When the cylinder 18 rotates, the metal conveyor belt 19 will also be driven to rotate. At this time, the heating elements 17 inside the first roller 104 and the second roller 105 can be activated simultaneously. The heating elements 17 will then heat the inside of the first roller 104 and the second roller 105. Since the heating elements 17 inside the first roller 104 are not as hot as those inside the second roller 105, the temperature inside the first roller 104 is higher than that inside the second roller 105. The internal temperature is low. At this time, the second motor 102 and the third motor 103 can be started to drive the second roller 105 and the first roller 104 to rotate respectively. Then the rubber sheet will be transported on the metal conveyor belt 19. First, it passes through the first roller 104, where its surface is initially heated. Then, it passes through the rotating second roller 105, where it is significantly heated. Finally, the preheated rubber sheet can be transported to the outside of the processing box 1 through the outlet groove 12. After the rubber sheet has been preheated by the first roller 104 and the second roller 105, the metal conveyor belt 19 will carry the rubber sheet into the bottom of the second fixed seat 21. At this time, it can be... After adjusting the height of the spring telescopic rod 2, the spring telescopic rod 2 will drive the roller 23 to adjust its height as well. When the roller 23 is adjusted to contact the rubber sheet, the spring telescopic rod 2 is released. At this time, the rubber sheet will be preheated and flattened in time. After the rubber sheet enters the processing box 1 through the inlet groove 11, the rubber sheet is placed on the bottom plate 31. Then, the lead screw 33 is inserted into the insertion hole 32 and the lead screw 33 is rotated. The lead screw 33 will then abut against the limiting seat 3. The more the lead screw 33 is rotated, the more the limiting seat 3 will move inward in the slide groove 34. When the limiting seat 3 contacts the rubber sheet, the rotation of the lead screw 33 is stopped. The rubber sheet is then limited by the limiting seat 3. Then, the air pump 41 can be started, and the air pump 41 will inject air into the air pipe 4. The air will then flow out through the air pipe 4 into the processing box 1 and onto the surface of the rubber sheet. After the first roller 104 and the second roller 105 have finished preheating the rubber sheet, water can be injected into the water tank 51. Then, the flexible water pipe 5 can be removed from the collar seat 52. The flexible water pipe 5 can be pulled to spray water mist onto the surface of the first roller 104 and the second roller 105. When the rubber sheet exits from the outlet groove 12, it will come into contact with the sponge block 6 on the side wall of the outlet groove 12. The water and dust on the surface of the rubber sheet will then be removed by the sponge block 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
