[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] As Figures 1 to 4 shown, a preheating device for rubber conveyor belt processing according to an embodiment of the present invention includes a preheating body 1; a layered cylinder 11 is fixedly connected to the top of the preheating body 1; two filter plates 12 are fixedly connected to the inner wall of the layered cylinder 11, and the two filter plates 12 are arranged in upper and lower layers; a blanking box 13 is fixedly connected to the bottom end of the filter plate 12, and the two blanking boxes 13 are arranged oppositely; a material guiding box 14 is fixedly connected to the bottom end of the blanking box 13 located at the bottom; a hot air blower 15 is fixedly connected to the bottom of the inner wall of the layered cylinder 11; a temporary storage component is arranged inside the preheating body 1, and the temporary storage component is used for temporarily storing and transporting the preheated rubber material; a stirring component is arranged inside the preheating body 1, and the stirring component is used for stirring and feeding the rubber material; when preheating and processing the raw material of the rubber conveyor belt, the preheating body 1 and the layered cylinder 11 are used as the main framework of the preheating device. First, the top of the layered cylinder 11 is opened to put in the rubber raw material. A large amount of rubber enters the inside of the layered cylinder 11 and is placed on the surface of the upper filter plate 12. Then the top of the layered cylinder 11 is closed. Subsequently, the hot air blower 15 works to blow hot air upward from the bottom inner wall of the layered cylinder 11. The hot air passes through the lower filter plate 12 and reaches the upper filter plate 12, preheating the rubber on the surface of the upper filter plate 12 for the first layer. The stirring component scrapes and stirs the rubber on the surface of the upper filter plate 12, and scrapes and stirs the rubber on the surface of the upper filter plate 12 to fall from the blanking box 13 to the surface of the lower filter plate 12. Since the lower filter plate 12 is close to the top of the hot air blower 15, the hot air blown from the hot air blower 15 has a stronger heating effect on the rubber on the lower filter plate 12, preheating the rubber on the surface of the lower filter plate 12 for the second layer. Because the second layer is closest to the air outlet of the hot air blower 15 and absorbs most of the heat first, and then part of the heat is discharged to the first layer, the second layer is hotter than the first layer. Subsequently, the rubber on the lower filter plate 12 is scraped and stirred by the stirring component and falls at the connection between another blanking box 13 and the material guiding box 14 for feeding. The fed rubber enters the temporary storage component for temporary storage, and the material can be taken out during use, playing a role in multi-layer preheating of the rubber raw material, reducing the occurrence of thermal stress in the rubber material, and preventing deformation or even cracking.

[0024] The stirring assembly includes a first servo motor 2, a rotating rod 21, and a scraper 22; the first servo motor 2 is fixedly connected inside the preheating body 1; the rotating rod 21 is fixedly connected to the output end of the first servo motor 2; two scraper 22 are fixedly connected to the outer wall of the rotating rod 21, and the two scrapers 22 are respectively located on the upper surfaces of the two filter plates 12, and the two scrapers 22 are arranged opposite to each other; when stirring and preheating the rubber raw material, the output end of the first servo motor 2 drives the rotating rod 21 to rotate, and the scraper 22 on the surface of the upper filter plate 12 scrapes and stirs the raw material to be evenly heated. Then, when it reaches the blanking box 13, it falls onto the surface of the lower filter plate 12, and the other scraper 22 then scrapes and stirs the rubber raw material again to be evenly heated until the rubber raw material is discharged from the other blanking box 13 and the material guiding box 14. The two scrapers 22 arranged opposite to each other can stir the rubber raw material alternately, playing a role in scraping and stirring the rubber raw material layer by layer and evenly preheating it.

[0025] As Figures 1 to 3 shown, the temporary storage assembly includes a temporary storage tank 3 and a sliding box 31; the temporary storage tank 3 is opened inside the preheating body 1 and is located on the side away from the stratification cylinder 11, and one end of the material guiding box 14 away from the blanking box 13 communicates with the inside of the temporary storage tank 3; the sliding box 31 is slidably connected to the inner wall of the temporary storage tank 3; when the scraper 22 scrapes and stirs the rubber raw material on the surface of the lower filter plate 12, the scraper 22 scrapes and stirs the rubber raw material and drops it into the blanking box 13 and the material guiding box 14. The rubber raw material slides along the inner wall of the material guiding box 14 and enters the inside of the temporary storage tank 3 for temporary storage. Part of the rubber raw material is temporarily stored on the inner wall of the sliding box 31. The top and bottom of the sliding box 31 are both open and in a square shape. During use, the sliding box 31 is pulled out of the inner wall of the preheating body 1, and the rubber raw material can be collected from the bottom of the sliding box 31, playing a role in temporarily storing and taking out the preheated rubber raw material.

[0026] As Figures 1 to 4As shown, the inner wall of the preheating body 1 is slidably connected with an L-shaped plate 4; a feeding port 41 is provided on the L-shaped plate 4 between the material guide box 14 and the temporary storage groove 3; a round block 42 is fixedly connected to the bottom end of the L-shaped plate 4 near the top of the No. 1 servo motor 2; a counterweight 43 is fixedly connected to the bottom center of the round block 42; a transmission component is provided on the outer wall of the rotating rod 21, and the transmission component is used to drive the L-shaped plate 4 to slide up and down to control the blocking of one end of the material guide box 14; when the second layer of preheated rubber raw materials falls and is temporarily stored, the output end of the No. 1 servo motor 2 is used to drive the rotating rod 21 to rotate, and the transmission component intermittently squeezes the round block 42, and whenever the transmission component squeezes the round block 42, the round block 42 and the L-shaped plate 4 are lifted up, and the counterweight 43 is pressed against the rotating rod 21. The weight block 43 is then lifted up, and the L-shaped plate 4 is lifted up and slides up. At this time, the discharge port 41, which was originally blocked with the outlet of the material guide box 14 in an interlaced manner, slides up. The discharge port 41 corresponds to the outlet of the material guide box 14 to realize the communication between the material guide box 14 and the inside of the temporary storage tank 3. The rubber raw material on the surface of the filter screen plate 12 below is scraped and stirred and discharged into the temporary storage tank 3 for temporary storage. As the output end of the rotating rod 21 continues to rotate, the transmission component releases the squeeze on the round block 42, and the counterweight block 43 counterweights the L-shaped plate 4 to make it fall. The discharge port 41 is again blocked with the outlet of the material guide box 14 in an interlaced manner, thereby realizing the function of controlling intermittent discharge at the outlet of the material guide box 14. At the same time, the L-shaped plate 4 can also synchronously control the excessive heat inside the stratification cylinder 11 to be discharged from the outlet of the material guide box 14.

[0027] The transmission assembly includes a disc 5 and an arc-shaped protrusion 51; the disc 5 is fixedly connected to the outer wall of the rotating rod 21; the arc-shaped protrusion 51 is fixedly connected to the upper surface of the disc 5, and the arc-shaped protrusion 51 is correspondingly arranged with the round block 42; when the L-shaped plate 4 is controlled to slide up and down, the output end of the No. 1 servo motor 2 drives the disc 5 on the outer wall of the rotating rod 21 to rotate, and the arc-shaped protrusion 51 rotates synchronously with the disc 5, and the arc-shaped protrusion 51 intermittently squeezes the round block 42, and lifts up the L-shaped plate 4 on the round block 42 to slide, when the arc-shaped protrusion 51 lifts up the round block 42, the discharge port 41 and the outlet of the material guide box 14 are correspondingly connected, and when the arc-shaped protrusion 51 moves away from the round block 42, the discharge port 41 and the outlet of the material guide box 14 are misaligned and blocked, which plays a role in controlling the up and down sliding of the L-shaped plate 4.

[0028] like Figures 1 to 3As shown, a diversion block 6 is fixedly connected to the inner wall of the temporary storage tank 3; a plugging plate 61 is slidably connected to the inner wall of the preheating body 1; an elastic member 62 is fixedly connected between the plugging plate 61 and the inner wall of the preheating body 1; an end of the plugging plate 61 is fixedly connected with a square convex block 63, and the square convex block 63 is located below the L-shaped plate 4; when quantitatively feeding materials into the temporary storage tank 3, the diversion block 6 is fixed on the inner wall of the temporary storage tank 3 as a feeding guide, and the preheated rubber raw materials fall from the outlet of the material guiding box 14 onto the slope of the diversion block 6 and then fall onto the plugging plate 61 for temporary storage. After the counterweight 43 drives the L-shaped plate 4 to slide down by gravity, the L-shaped plate 4 squeezes the square convex block 63, and the plugging plate 61 slides down along with it to squeeze the elastic member 62 to contract and be stressed on the inner wall of the preheating body 1. At this time, the plugging plate 61 that was originally in contact with the diversion block 6 slides down, and the rubber raw materials on the plugging plate 61 fall along the slope of the plugging plate 61 onto the inner wall of the sliding box 31. When the arc-shaped convex block 51 squeezes the L-shaped plate 4 to slide up again, the plugging plate 61 is pushed up by the elastic force of the elastic member 62 to fit the bottom surface of the diversion block 6 to block the feeding. At this time, the sliding box 31 is pulled to slide, and the temporarily stored rubber raw materials are pulled out for feeding, which plays a role in quantitatively feeding the rubber inside the temporary storage tank 3.

[0029] A gas guide pipe 7 is connected between the inner wall of the temporary storage tank 3 and the inner wall of the layered cylinder 11; a one-way valve 71 is fixedly connected to the gas guide pipe 7; when the hot air blower 15 works to heat the inside of the layered cylinder 11, the gas guide pipe 7 will be connected between the top of the layered cylinder 11 and the top of the temporary storage tank 3. A large amount of heat is absorbed by the rubber in the first layer and the second layer, and part of the remaining heat enters from one end of the gas guide pipe 7 at the top of the layered cylinder 11, passes through the one-way valve 71, and then reaches the inside of the temporary storage tank 3 from the other end of the gas guide pipe 7, recycling the remaining heat to keep the rubber raw materials temporarily stored inside the temporary storage tank 3 warm, playing a role in recycling waste heat.

[0030] As Figures 1 to 3 、 Figure 5 As shown, a conveyor 8 is fixedly connected to the side wall of the preheating body 1; a second servo motor 81 is fixedly connected to the conveyor 8; two rollers 82 are rotatably connected to the inner wall of the conveyor 8, and the output end of the second servo motor 81 is fixedly connected to one roller 82; when conveying and processing the rubber raw materials scraped off by the sliding box 31, the output end of the second servo motor 81 drives one roller 82 to rotate, synchronously driving the other roller 82 on the conveyor 8 to rotate. The sliding box 31 scrapes the temporarily stored rubber raw materials onto the conveyor belt connected by the two rollers 82, conveying and processing the preheated rubber raw materials, playing a role in taking and conveying the preheated rubber raw materials.

[0031] Both ends of the rotating roller 82 are fixedly connected with disk wheels 9; a first connecting rod 91 is hinged on the disk wheel 9; a second connecting rod 92 is hinged on the first connecting rod 91; on the outer wall of the preheating body 1 and on both sides close to the sliding box 31, limiting rods 93 are respectively fixedly connected; on both sides of the sliding box 31, connecting frames 94 are fixedly connected, the connecting frames 94 are hinged to one end of the second connecting rod 92, and the connecting frames 94 are slidably connected to the inner walls of the limiting rods 93; when the sliding box 31 is used to take the temporarily stored rubber raw materials, the two rotating rollers 82 rotate synchronously with the output end of the second servo motor 81, the two disk wheels 9 connected to both ends of one rotating roller 82 rotate accordingly, the disk wheels 9 drive the first connecting rod 91 to rotate synchronously, and the second connecting rod 92 also pushes the connecting frame 94 to slide on the inner wall of the limiting rod 93 as the first connecting rod 91 rotates, and the connecting frames 94 on both sides of the sliding box 31 drive the sliding box 31 to reciprocate, so as to realize the function of driving the sliding box 31 to reciprocally receive and deliver materials.

[0032] As Figures 1 to 3 shown, a material guiding disk 95 is fixedly connected to the top end of the layering cylinder 11, and the shape of the material guiding disk 95 is trumpet-shaped; a top cover 96 is slidably connected to the material guiding disk 95; when rubber raw materials are put into the layering cylinder 11, pull the top cover 96 upwards to open the top of the material guiding disk 95, put the rubber raw materials into the top opening of the material guiding disk 95, the top end of the material guiding disk 95 presents an open trumpet shape, which can guide the rubber raw materials into the interior of the layering cylinder 11 for preheating. After the rubber raw materials are put in, then cover the top cover 96 on the material guiding disk 95 to achieve sealing, playing the role of guiding and sealing the top of the layering cylinder 11.

[0033] Working process: When preheating the raw materials of the rubber conveyor belt, the preheating body 1 and the layering cylinder 11 are used as the main framework of the preheating device. First, open the top of the layering cylinder 11 and put in the rubber raw materials. A large amount of rubber enters the inside of the layering cylinder 11 and is placed on the surface of the upper filter screen plate 12. Then, close the top of the layering cylinder 11. Subsequently, the hot air blower 15 works to blow hot air upward from the bottom inner wall of the layering cylinder 11. The hot air passes through the lower filter screen plate 12 and reaches the upper filter screen plate 12, preheating the rubber on the surface of the upper filter screen plate 12 for the first layer. The stirring component scrapes and stirs the rubber on the surface of the upper filter screen plate 12, scraping and stirring the rubber on the surface of the upper filter screen plate 12 from the feeding box 13 to the surface of the lower filter screen plate 12. Since the lower filter screen plate 12 is close to the top of the hot air blower 15, the hot air blown out by the hot air blower 15 has a stronger heating effect on the rubber on the lower filter screen plate 12, preheating the rubber on the surface of the lower filter screen plate 12 for the second layer. Because the second layer is closest to the air outlet of the hot air blower 15 and absorbs most of the heat first, and then part of the heat is discharged to the first layer, the second layer is hotter than the first layer. Subsequently, the rubber on the lower filter screen plate 12 is scraped and stirred by the stirring component and falls at the connection of another feeding box 13 and the guiding box 14 for feeding. The fed rubber enters the temporary storage component for temporary storage, and the material can be taken out during use, playing a role in multi-layer preheating of the rubber raw materials, reducing the occurrence of thermal stress in the rubber material, which may cause deformation or even cracking; When stirring and preheating the rubber raw materials, the output end of the first servo motor 2 drives the rotating rod 21 to rotate. The scraping plate 22 on the surface of the upper filter screen plate 12 scrapes and stirs the raw materials to be evenly heated. Then, when it reaches the feeding box 13, it falls to the surface of the lower filter screen plate 12. Another scraping plate 22 then scrapes and stirs the rubber raw materials again to be evenly heated until the rubber raw materials are fed from another feeding box 13 and the guiding box 14. The two scraping plates 22 are arranged oppositely and can stir the rubber raw materials alternately, playing a role in scraping, stirring, and evenly preheating the rubber raw materials in layers; When the scraping plate 22 scrapes and stirs the rubber raw materials on the surface of the lower filter screen plate 12, the scraping plate 22 scrapes and stirs the rubber raw materials into the feeding box 13 and the guiding box 14. The rubber raw materials slide down along the inner wall of the guiding box 14 and enter the inside of the temporary storage tank 3 for temporary storage. Part of the rubber raw materials are temporarily stored on the inner wall of the sliding box 31. The top and bottom of the sliding box 31 are both open and in a square shape. During use, pull the sliding box 31 out of the inner wall of the preheating body 1, and the rubber raw materials can be collected from the bottom of the sliding box 31, playing a role in temporarily storing and taking out the preheated rubber raw materials;When the preheated rubber raw material on the second layer falls and is temporarily stored, the output end of the first servo motor 2 drives the rotating rod 21 to rotate, and the transmission component intermittently squeezes the round block 42. Whenever the transmission component squeezes the round block 42, the round block 42 and the L-shaped plate 4 are lifted, and the counterweight block 43 is driven to be lifted accordingly. The L-shaped plate 4 is lifted and slides upward. At this time, the material outlet 41 that was originally staggered and blocked with the outlet of the material guiding box 14 slides upward, and the material outlet 41 corresponds to the outlet of the material guiding box 14 to realize the connection between the material guiding box 14 and the inside of the temporary storage tank 3. The rubber raw material on the surface of the lower filter screen plate 12 is scraped and stirred and falls into the temporary storage tank 3 for temporary storage. As the output end of the rotating rod 21 continues to rotate, the transmission component releases the extrusion of the round block 42, and the counterweight block 43 weights the L-shaped plate 4 to make it fall, and the material outlet 41 is staggered and blocked with the outlet of the material guiding box 14 again, realizing the function of controlling intermittent feeding at the outlet of the material guiding box 14. At the same time, the L-shaped plate 4 can also synchronously control the excessive heat inside the stratification cylinder 11 to be discharged from the outlet of the material guiding box 14; when controlling the L-shaped plate 4 to slide up and down, the output end of the first servo motor 2 drives the disc 5 on the outer wall of the rotating rod 21 to rotate, and the arc-shaped convex block 51 rotates synchronously with the disc 5. The arc-shaped convex block 51 intermittently squeezes the round block 42 and lifts and slides the L-shaped plate 4 on the round block 42. When the arc-shaped convex block 51 lifts the round block 42, the material outlet 41 corresponds to and penetrates the outlet of the material guiding box 14. When the arc-shaped convex block 51 turns away from the round block 42, the material outlet 41 is misaligned and blocked with the outlet of the material guiding box 14, playing a role in controlling the up and down sliding of the L-shaped plate 4; When quantitatively feeding the inside of the temporary storage tank 3, the diversion block 6 is fixed on the inner wall of the temporary storage tank 3 as a feeding guide. The preheated rubber raw material falls from the outlet of the material guiding box 14 to the slope of the diversion block 6 and then falls on the blocking plate 61 for temporary storage. After the counterweight block 43 drives the L-shaped plate 4 to slide down by gravity, the L-shaped plate 4 squeezes the square convex block 63, and the blocking plate 61 slides down and squeezes the elastic member 62 on the inner wall of the preheating body 1 to contract and be stressed. At this time, the blocking plate 61 that was originally attached to the diversion block 6 slides down, and the rubber raw material on the blocking plate 61 falls along the slope of the blocking plate 61 to the inner wall of the sliding box 31. When the arc-shaped convex block 51 squeezes the L-shaped plate 4 to slide up again, the blocking plate 61 is pushed up by the elastic force of the elastic member 62 to fit the bottom surface of the diversion block 6 to block the feeding. At this time, pull the sliding box 31 to slide and pull out the temporarily stored rubber raw material for feeding, playing a role in quantitatively feeding the rubber inside the temporary storage tank 3; When the hot air blower 15 works to heat the inside of the stratification cylinder 11, the air guide pipe 7 will be connected at the top of the stratification cylinder 11 and the top of the temporary storage tank 3. A large amount of heat is absorbed by the rubber on the first layer and the second layer. Part of the remaining heat enters from one end of the air guide pipe 7 at the top of the stratification cylinder 11, passes through the one-way valve 71, and then reaches the inside of the temporary storage tank 3 from the other end of the air guide pipe 7, recovering the remaining heat for insulating the rubber raw material temporarily stored inside the temporary storage tank 3, playing a role in recovering waste heat; When transporting and processing the rubber raw materials scraped off by the sliding box 31, the output end of the second servo motor 81 drives a roller 82 to rotate, synchronously driving another roller 82 on the conveyor 8 to rotate. The sliding box 31 scrapes the temporarily stored rubber raw materials onto the conveyor belt connected by the two rollers 82, transports and processes the preheated rubber raw materials, and plays a role in feeding and transporting the preheated rubber raw materials; when using the sliding box 31 to take the temporarily stored rubber raw materials, the two rollers 82 rotate synchronously with the output end of the second servo motor 81, and the two discs 9 connected to both ends of one roller 82 rotate accordingly. The disc 9 drives the first connecting rod 91 to rotate synchronously, and the second connecting rod 92 also pushes the connecting frame 94 to slide on the inner wall of the limiting rod 93 as the first connecting rod 91 rotates. The connecting frames 94 on both sides of the sliding box 31 drive the sliding box 31 to reciprocate, thus realizing the function of driving the sliding box 31 to receive and feed materials reciprocally. When putting rubber raw materials into the stratification cylinder 11, pull the top cover 96 upwards to open the top of the material guiding plate 95, and put the rubber raw materials into the top opening of the material guiding plate 95. The top end of the material guiding plate 95 is in the shape of an open trumpet, which can guide the rubber raw materials into the interior of the stratification cylinder 11 for preheating. After the rubber raw materials are put in, then cover the top cover 96 on the material guiding plate 95 to achieve sealing, playing a role in guiding and sealing the top of the stratification cylinder 11.
