Description

Technical Field

[0001] The invention relates to the technical field of molding materials, and in particular to a high-efficiency and energy-saving rubber snow-melting pad processing device. Background Art

[0002] Snow melting rubber pad is a kind of rubber block formed by mixing natural rubber NR or styrene butadiene rubber SBR as raw materials. It has a built-in heating wire in the middle and is covered with insulating materials such as FEP or SR around the heating wire. At the same time, the outermost metal braided mesh is connected to the ground wire of the external three-core power line to reduce the risk of leakage. Finally, it is formed by pressing through vulcanization equipment. With the continuous development of industry and the continuous advancement of technology, the requirements for the accuracy, efficiency and quality of material processing are getting higher and higher. In order to meet these needs, the open mill has been continuously improved in terms of structural design, automatic control, and material selection. For example, a more advanced transmission system is used to achieve more stable roller speed control; an automatic temperature adjustment system is added to ensure that the material is in a suitable temperature environment during the processing process; in terms of materials, higher strength and better wear resistance materials are selected to manufacture rollers to extend the service life of the equipment.

Through the above technical solution, the rubber passes through the lower material bin and the upper material bin after coming out from the lower side of the bottom roller 2, has been folded, and then passes between the steering roller and the bogie to be completely folded into two layers. The coating added to the rubber by the lower coating wheel 1, the lower coating wheel 2 and the upper coating wheel is also located inside the folded rubber, and then passes through the parallel rollers so that it is completely parallel to the upper roller 1 after folding, reducing the interference of the external environment, and the coating is even and not easy to splash and fall.

[0007] Furthermore, the coating assembly includes a loading box, one end of which is fixedly mounted on a vertical mounting plate, and the other end of which is suspended in the air.

[0009] Furthermore, the vulcanization assembly includes a mounting shaft, which is fixedly mounted on the base plate, on which an upper module is fixedly mounted, on which a lower module is slidably mounted, on which a lifting shaft is slidably mounted, and on which an extrusion plate is fixedly mounted at the lower side.

[0010] Furthermore, a friction shaft is slidably mounted on the upper module, a friction arc plate is fixedly mounted on the friction shaft, the friction arc plate is in close contact with the lifting shaft, and a friction spring is mounted between the upper module and the friction arc plate so that the friction arc plate squeezes the lifting shaft.

[0011] Furthermore, an upper baffle is installed on the side of the upper module, a lower baffle is installed on the side of the lower module, a protruding block is fixed on the lower baffle, the protruding block is elastic, and a groove is provided on the upper module, which is located on the lower side of the upper baffle.

When the internal pressure of the rubber pad increases, it will push the extrusion plate and the lifting shaft to overcome the friction force and move. The pressure on the snow-melting pad can be changed by controlling the size of the friction force. After the lower module and the upper module are fitted together, they can be stuck in the groove, and the upper bar moves downward to expose the vent hole for exhaust. At this time, due to the small vertical rod between the lower bar and the upper bar, the lower module does not move downward, and the exhaust is completed without separating the lower module and the upper module, thereby avoiding the change of the force position when the rubber pad is squeezed.

[0013] The beneficial effects of the present invention compared with the prior art are: (1) Through the technical solution of the present invention, a foaming agent can be added to the rubber pad of the lower layer during the production of the rubber snow-melting pad. After adding the foaming agent, the heat insulation and waterproof effects can be greatly improved. The lower mold of the rubber snow-melting pad after molding has low thermal conductivity and heat insulation due to the foamed pore structure. The heat of the heat-conducting wire is transported through the upper structure, which can greatly improve the energy efficiency. The snow melting efficiency is improved and the energy consumption is reduced.

[0014] (2) Through the technical solution of the present invention, after the rubber comes out from the lower side of the bottom roller 2, it passes through the lower material bin and the upper material bin, has been folded, and then passes through the steering roller and the bogie to be completely folded into two layers. The coating added to the rubber by the lower coating wheel 1, the lower coating wheel 2 and the upper coating wheel is also located inside the folded rubber, and then passes through the parallel rollers so that it is completely parallel to the upper roller 1 after folding, thereby reducing the interference of the external environment, and the coating is even and not easy to splash and fall.

[0015] (3) Through the technical solution of the present invention, the folded position of the rubber is located at the suspended end of the loading box, the lower layer inside the rubber can fit with the coating roller, and the coating roller can evenly bring the foaming agent out of the loading box and quickly push it onto the rubber through the pushing plate, and can accurately control the amount of foaming agent applied.

[0016] (4) Through the technical solution of the present invention, the rubber of the lower layer of the snow-melting pad will expand during the vulcanization process. The position-variable extrusion plate can be set to adapt to the expansion, and the friction arc plate is used to squeeze the lifting shaft to ensure that the internal pressure remains unchanged as the rubber pad expands. When the internal pressure of the rubber pad increases, it will push the extrusion plate and the lifting shaft to overcome the friction force and move. By controlling the magnitude of the friction force, the pressure on the snow-melting pad can be changed. After the lower module and the upper module are fitted together, they can be stuck in the groove, and the upper bar moves downward to expose the vent hole for exhaust. At this time, due to the small vertical rod between the lower bar and the upper bar, the lower module does not move downward, and the exhaust is completed without separating the lower module and the upper module, thereby avoiding the change of the force position when the rubber pad is squeezed.

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0031] like Figure 1-Figure 12As shown, a highly efficient and energy-saving rubber snow-melting pad processing equipment includes a bottom plate 4, on which a refining assembly 1 and a vulcanizing assembly 3 are mounted, and a shell 5 is arranged on the outside of the vulcanizing assembly 3. The upper and lower rubber pads of the snow-melting pad in this case are made of different materials and different thicknesses. Before vulcanization during the initial production, the upper rubber pad is thicker than the lower layer. A foaming agent is added to the lower rubber pad for foaming. After foaming and expansion, the heat insulation and waterproof effects can be improved. The whole is formed into a finished snow-melting rubber pad. In general, the multi-stage one-piece molding structure of the snow-melting rubber pad is stable, the middle heating wire can evenly transfer heat, the structure is reasonable, and the force is relatively uniform.

[0032] In this embodiment, if Figure 3 The open refining assembly 1 includes a vertical mounting plate 101, two vertical mounting plates 101 are provided, and are fixedly installed on the bottom plate 4. The vertical mounting plate 101 is provided with a bottom roller 102, a bottom roller 103, an upper roller 114, and an upper roller 115. The bottom roller 102 and the bottom roller 103 are respectively controlled to rotate by a bottom motor 118 and a bottom motor 119, and the upper roller 114 and the upper roller 115 are respectively controlled to rotate by an upper motor 116 and an upper motor 117. The middle position of the vertical mounting plate 101 is provided with a lower material bin 104 and an upper material bin 109, and the end of the lower material bin 104 is provided with a first inclined surface 1 07 and the second inclined surface 108 form an obtuse angle, and a large rounded corner is also set on the lower side of the lower silo 104. After the rubber comes out from between the bottom roller 102 and the bottom roller 2 103, it goes upward from the bottom roller 2 103 to fit with the first inclined surface 107 and the second inclined surface 108. The upper silo 109 forms an acute angle on both sides, and then the rubber continues to move upward, and the side of the upper silo 109 fits. The vertical mounting plate 101 is fixed with a bogie 111, and the bogie 111 is rotatably mounted with a steering roller 112. The vertical mounting plate 101 is fixed with a coating component 2, and the coating component 2 is filled with a foaming agent. After the rubber pad is folded in half, the coating component 2 is coated from the middle part of the rubber pad. In the process of making the rubber snow melting pad, a foaming agent can be added to the rubber pad of the lower layer. After adding the foaming agent, the heat insulation and waterproof effects can be greatly improved. If the foaming agent is only added to the lower layer, more heat will be transferred upward, which can improve the snow melting efficiency and reduce energy consumption.

[0033] In this embodiment, the first inclined surface 107 is rotatably provided with the lower coating wheel 105, the second inclined surface 108 is rotatably provided with the lower coating wheel 106, and the lower material bin 104 is provided with the coating. The upper coating wheel 110 is rotatably provided with the two side surfaces of the upper material bin 109. When the rubber passes through the lower material bin 104 and the upper material bin 109, it will rub the lower coating wheel 105, the lower coating wheel 106, and the upper coating wheel 110 to rotate, and the internal coating will be brought out during the rotation process for coating. The upper material bin 109 is provided with the coating inside. The steering roller 112 is installed at a 45-degree angle to the bottom roller 2 103. The rubber is folded in half after passing through the lower material bin 104 and the upper material bin 109. After being folded in half, it will be perpendicular to the upper roller 1 14. The steering roller 112 twists the direction. A parallel roller 113 is fixed on the vertical mounting plate 101. The rubber passes through the parallel roller 113 and fits with the coating component 2, and finally enters between the upper roller 1 114 and the upper roller 2 115. After the rubber comes out from the lower side of the bottom roller 103, it passes through the lower material bin 104 and the upper material bin 109, has been folded, and then passes through the steering roller 112 and the bogie 111 to be completely folded into two layers. The coating added to the rubber by the lower coating wheel 105, the lower coating wheel 2 106 and the upper coating wheel 110 is also located inside the folded rubber, and then passes through the parallel roller 113 to make it completely parallel to the upper roller 114 after folding, reducing interference from the external environment, and it is not easy to fall everywhere inside the folded rubber, and the coating is evenly applied and not easy to splash and fall.

[0034] In this embodiment, if Figure 2 , Figure 4-Figure 7As shown, the coating assembly 2 includes a loading box 204, one end of which is fixedly mounted on the vertical mounting plate 101, and the other end of the loading box 204 is suspended. The loading box 204 is filled with a foaming agent, which is in powder form. A coating roller 205 is rotatably mounted in the loading box 204, and the lower side of the loading box 204 is open. Roller notches 206 are evenly arranged on the circumferential surface of the coating roller 205; a total of five are arranged, and five portions of foaming agent are added in one rotation. The foaming agent will fall into the roller notch 206, and as the coating roller 205 rotates, it falls on the rubber, and a push plate 207 is slidably mounted in the roller notch 206. A sealing plate 208 is fixedly mounted on one end of the material plate 207, and the sealing plate 208 is fitted with the inner side of the vertical mounting plate 101 to prevent the internal foaming agent from leaking out. A feeding port 201 is arranged on the vertical mounting plate 101, and the feeding port 201 is connected with the loading box 204, and the outer side of the feeding port 201 is connected with the loading assembly, which is not shown in this embodiment. This is the prior art and is not elaborated on. A protective cover 202 is fixedly mounted on the vertical mounting plate 101, and a limit block 210 is fixedly mounted on the inner side of the protective cover 202. The lower side portion of the feeding port 201 is arranged to be concave away from the axis, and the push plate 207 is fitted in the limit block 210 and rotates. The push plate 207 rotates with the coating roller 205, but one end of the push plate 207 is squeezed by the limit block 210, so that the roller gap 206 is exposed. At this time, the foaming agent can enter the roller gap 206 and is located on the outside of the push plate 207 (the outside here refers to the side away from the axis of the coating roller 205). When the roller gap 206 opens downward, the push plate 207 also enters the concave position of the limit block 210 away from the axis. At this time, the push spring 209 drives the push plate 207 to push the roller gap The foaming agent squeezed by the mouth 206 is pushed out, and a coating motor 203 is fixedly mounted on the end of the protective sleeve 202. The rotating shaft of the coating motor 203 is connected to the coating roller 205, driving the coating roller 205 to rotate. The folded position of the rubber is located at the suspended end of the loading box 204, and the lower layer inside the rubber can fit with the coating roller 205. The coating roller 205 can evenly bring the foaming agent out of the loading box 204, and quickly push it onto the rubber through the pushing plate 207, and can accurately control the amount of foaming agent applied.

[0035] In this embodiment, if Figure 8-Figure 11As shown, the vulcanization assembly 3 includes a mounting shaft 301, and there are four mounting shafts 301 in total. The mounting shaft 301 is fixedly mounted on the bottom plate 4, and an upper module 303 is fixedly mounted on the mounting shaft 301. The upper module 303 is located at the upper part of the mounting shaft 301. The mounting shaft 301 fixes the four corners of the upper module 303. The mounting shaft 301 is slidably mounted with a lower module 302. The four corners of the lower module 302 are also slidably mounted on the mounting shaft 301. The lower module 302 and the upper module 303 are fixedly mounted on the mounting shaft 301. 03 is provided with a large groove inside for placing the parts of the snow melting pad, and openings are provided at both ends of the large groove. The opening of the lower module 302 is detachably installed with a lower baffle 310 for blocking, and the opening of the upper module 303 is detachably installed with an upper baffle 309 for blocking. This design is conducive to cleaning and maintenance. A lifting shaft 308 is slidably installed on the upper module 303, and an extrusion plate 317 is fixedly installed on the lower side of the lifting shaft 308. The extrusion plate 317 is located in the large groove of the upper module 303. A friction shaft 305 is slidably mounted on the upper module 303. Specifically, two connecting ears are arranged on the upper module 303. Two friction shafts 305 are arranged and slidably mounted on the two connecting ears respectively. A limit plate 304 is fixedly mounted on the first end of the friction shaft 305 to prevent slipping. A friction arc plate 307 is fixedly mounted on the second end of the friction shaft 305. The friction arc plate 307 is tightly attached to the lifting shaft 308. A friction spring 306 is installed between the upper module 303 and the friction arc plate 307 so that the friction arc plate 307 squeezes the lifting shaft 308. Specifically, the friction spring 306 is sleeved on the friction shaft 305. The first end of the friction spring 306 is fixedly connected to the connecting ear, and the second end is fixedly connected to the friction arc plate 307.

[0036] In this embodiment, an upper baffle plate 309 is installed on the side of the upper module 303, and a lower baffle plate 310 is installed on the side of the lower module 302. A protruding block 315 is fixedly installed on the lower baffle plate 310, and the protruding block 315 is elastic. A groove 316 is provided on the upper module 303, which is located at the lower side of the upper baffle plate 309. When the lower module 302 and the upper module 303 are fitted together, the protruding block 315 is stuck in the groove 316. A lifting hydraulic cylinder 311 is fixedly installed on the bottom plate 4, and a lower-layer stop bar 312 is fixedly installed on the cylinder arm of the lifting hydraulic cylinder 311, and an upper-layer stop bar 314 is fixedly installed on the lower-layer stop bar 312, and a small vertical rod is arranged between the lower-layer stop bar 312 and the upper-layer stop bar 314, and a fixing plate 313 is fixedly installed on the side of the lower module 302, and the fixing plate 313 is slidably connected with the small vertical rod on the lower-layer stop bar 312, and the whole is in the shape of an "I", and after the lower-layer stop bar 312 is fitted with the fixing plate 313, the lifting hydraulic cylinder 311 drives the fixing plate 313 and the lower module 302 to rise. The lower rubber layer of the snow-melting pad will expand during the vulcanization process, which can be adapted by setting a position-variable extrusion plate 317, and the friction arc plate 307 is used to squeeze the lifting shaft 308 to ensure that the internal pressure remains unchanged as the rubber pad expands. When the internal pressure of the rubber pad expands, the extrusion plate 317 and the lifting shaft 308 will be pushed to overcome the friction force and move. The pressure on the snow-melting pad can be changed by controlling the size of the friction force. After the lower module 302 and the upper module 303 are fitted together, they can be stuck in the groove 316, and the upper stop bar 314 moves downward to expose the vent hole 318 for exhaust. At this time, due to the small vertical rod between the lower stop bar 312 and the upper stop bar 314, the lower module 302 will not move downward, and the lower module 302 and the upper module 303 are not separated. Exhaust is completed without separating, thereby avoiding the change of the force position when the rubber pad is squeezed.

[0037] Working principle: The first step is to start refining; Figure 3 As shown, the raw materials are placed in the open mill assembly 1 for open milling. The rubber comes out from the bottom roller 102 and the bottom roller 2 103 and adheres to the first inclined surface 107 and the second inclined surface 108, and begins to form an angle. Then, it passes through the upper material bin 109, and the two sides of the upper material bin 109 form an acute angle. The rubber adheres to further reduce the angle (as shown in FIG. Fig.12At the same time, the lower coating wheel 105, the lower coating wheel 2 106 and the upper coating wheel 110 roll to coat the rubber, and then the two sides of the rubber are folded together and passed through the steering roller 112, and then turned by the steering roller 112, and then passed through the parallel roller 113, and the parallel roller 113 makes the folded rubber parallel to the upper roller 114, and then the folded part of the folded rubber is attached to the suspended end of the charging box 204, and the open part is close to the installation end of the charging box 204, and then the coating motor 203 is started, and the coating motor 203 drives the coating roller As the wheel 205 rotates, the push plate 207 on the coating roller 205 is squeezed by the limit block 210, and the foaming agent enters the roller gap 206. When the corresponding push plate 207 rotates downward, the push plate 207 will be pushed by the push spring 209 due to the shape of the limit block 210 and coated on the rubber. Since the foaming agent is powdery, it is not easy to scatter when coated on the inside of the folded rubber. Subsequently, the rubber enters between the upper roller 1 114 and the upper roller 2 115, and then returns to between the bottom roller 1 102 and the bottom roller 2 103, and this process is repeated until completion.

[0038] The second step is vulcanization. The rubber pad with foaming agent is placed in the large groove of the lower module 302, and then the heat conducting wire is placed. The rubber pad without foaming agent is placed on the upper layer, and the lifting hydraulic cylinder 311 is started. The lifting hydraulic cylinder 311 drives the lower block 312 to fit the lower side of the fixed plate 313, and drives the lower module 302 to move upward, and stops when the protruding block 315 is embedded in the groove 316. Then the lifting shaft 308 is moved downward to make the lifting shaft 308 fit the upper rubber pad, and then the time, temperature and Pressure, the vulcanization pressure of the foam rubber is 3MPa, the vulcanization temperature is 145℃, and the vulcanization time is 15min). During the vulcanization process, exhaust is required. At this time, the lifting hydraulic cylinder 311 moves downward to make the upper block 314 fit with the upper side of the fixed plate 313. During this process, the lower module 302 is stuck by the upper module 303 and the upper block 314 moves downward to expose the vent 318 for exhaust. Then the lifting hydraulic cylinder 311 drives the upper block 314 to move upward to block the vent 318, and this is repeated.

[0039] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
