Description
Technical Field
[0001] This utility model relates to the field of powder processing technology, and in particular to a heat dissipation structure for powder pressure rollers. Background Technology
[0002] In the field of powder processing, powder rollers play a crucial role. They are used to press mixed raw materials into sheets after they have been melted and cross-linked by a twin-screw extruder, and then crushed, ground and sieved.
[0003] During operation, the powder rollers generate a significant amount of heat due to continuous pressure and material friction. During prolonged continuous operation, the surface temperature of the rollers can rapidly rise to tens of degrees Celsius or even higher. If this heat cannot be dissipated in time, it will severely impact the processing quality of the powder material. Furthermore, the high temperature will significantly damage the rollers themselves. Sustained high temperatures accelerate the wear of the roller material, reduce its hardness and strength, leading to surface defects such as deformation and cracks. This significantly shortens the rollers' lifespan, increases equipment maintenance costs and downtime, and affects production efficiency. Common heat dissipation methods include air cooling or installing ventilation holes on the roller surface, but these methods often fail to dissipate the internal heat effectively. Therefore, this application provides a powder roller heat dissipation structure to meet the requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a heat dissipation structure for powder rollers, which can conduct heat out of the inside of the rollers, thereby avoiding the problem that the heat inside the rollers cannot be dissipated in time.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A powder roller heat dissipation structure includes a roller body, wherein the roller body is a hollow structure and both sides are fixedly connected with annular baffles. Two cover plates, both of which are circular structures that fit against the two sides of the roller body, and an annular plate is fixedly connected to one side of each cover plate; A disassembly / assembly structure is provided between the cover plate and the annular baffle. The fin structure is disposed between the cover plate and the annular baffle. The fin structure includes a heat dissipation fin. A first rectangular slot is provided on one side of the annular baffle, and a second rectangular slot is provided on one side of the cover plate. The heat dissipation fin is inserted into the inner wall of the first rectangular slot and the second rectangular slot. A protective structure is provided on one side of the cover plate.
[0006] The heat dissipation fins are inserted between the annular baffle and the cover plate through the first rectangular slot and the second rectangular slot, eliminating the need for complex welding. This significantly increases the heat dissipation area inside the pressure roller, accelerates the heat conduction generated by friction and pressure on the roller body, and the disassembly structure facilitates quick removal of the cover plate for cleaning or replacement of the fins, reducing equipment downtime and lowering maintenance costs.
[0007] Optionally, the disassembly and assembly structure includes a first screw hole, which is opened on one side of the annular baffle, and a second screw hole is opened on one side of the cover plate. The inner walls of the first screw hole and the second screw hole are threadedly connected to a first threaded clamp.
[0008] The threaded connection eliminates the need for complex snaps or welding. A regular wrench is all that's needed to fix or remove the cover plate from the annular baffle. The tight fit between the threaded rod and the threaded hole ensures that the cover plate does not shift or loosen when the pressure roller is running at high speed, preventing the heat dissipation fins from falling off and heat dissipation from failing due to structural shaking.
[0009] Optionally, a rectangular baffle is fixedly connected to the outer surface of the heat dissipation fins.
[0010] The rectangular baffle fits against the surface of the cover plate, forming an axial limit on the heat dissipation fins, preventing the fins from sliding along the length of the slot when the pressure roller rotates at high speed, and ensuring that the fins always maintain close contact with the roller body and the cover plate.
[0011] Optionally, a third screw hole is provided on one side of the rectangular baffle, and a fourth screw hole is provided on one side of the cover plate. The inner walls of the third screw hole and the fourth screw hole are threadedly connected to a second threaded rod.
[0012] The threaded clamp can rigidly connect the rectangular baffle and the cover plate, eliminating the risk of displacement of the fins and baffles when the pressure roller vibrates or operates at high speed. It is suitable for high-load, long-term continuous production scenarios.
[0013] Optionally, a heat dissipation plate is provided on one side of the cover plate, and a roller is fixedly connected to one side of the cover plate.
[0014] The heat dissipation plate is attached to the outside of the cover plate, which can directly dissipate the heat conducted by the cover plate to the outside air, and "auxiliary heat dissipation surface" is added on both sides of the pressure roller.
[0015] Optionally, the protective structure includes a vertical ring plate and a circular filter plate. One side of the vertical ring plate is fixedly connected to one side of the cover plate, and a horizontal ring plate is fixedly connected to one side of the vertical ring plate. An annular clamping plate is fixedly connected to one side of the circular filter plate, and the annular clamping plate engages with the inner wall of the horizontal ring plate.
[0016] The circular filter plate has a filtration function, which can prevent dust, fibers and other impurities in the air from adhering to the surface of the heat sink and affecting the heat dissipation effect.
[0017] Optionally, a circular insertion hole is provided on one side of the circular filter plate, and the roller is inserted into the circular insertion hole.
[0018] The circular insertion hole allows the roller to pass smoothly through the circular filter plate, avoiding spatial conflict between the protective structure and the transmission component roller, and ensuring that the installation of the protective structure does not affect the normal operation of the pressure roller.
[0019] Optionally, a fifth screw hole is provided on one side of the circular filter plate, and a sixth screw hole is provided on one side of the transverse annular plate. The inner walls of the fifth and sixth screw holes are threaded with a third threaded clamp.
[0020] The threaded connection rigidly fixes the circular filter plate to the transverse ring plate, preventing the filter plate from shifting or falling off due to high-speed operation of the pressure roller or workshop vibration, thus ensuring the continuous effectiveness of the filtration function.
[0021] Optionally, an annular block is fixedly connected to one side of the circular filter plate, and a rubber ring is snapped into the inner wall of the annular block.
[0022] The rubber ring fits against the outer surface of the roller shaft and the inner wall of the annular block, filling the tiny gap between the circular insertion hole and the roller shaft, completely preventing dust from entering from the roller shaft.
[0023] Compared with the prior art, this utility model has at least the following beneficial effects: Through the combined action of the finned structure and the disassembly structure, the disassembly structure can connect the cover plate to the finned structure and the roller body for installation. This allows the heat dissipation fins to transfer internal heat to the outside of the roller body. Compared to rollers without finned structures, the internal heat dissipation contact area is increased, thereby improving the overall heat dissipation effect and enabling the internal heat to be dissipated in a timely manner. The protective structure can protect traditional heat sinks and other structures, thereby preventing dust from adhering to them and affecting their heat dissipation effect. It also assists the finned structure in improving the overall heat dissipation effect, allowing the heat inside the roller body to dissipate in a timely manner. Attached Figure Description

[0033] The powder roller heat dissipation structure provided in this embodiment aims to solve the problem of poor heat dissipation inside the roller. It offers the following technical solutions to address the issues of heat accumulation inside the roller and the tendency of traditional heat dissipation plates to attract dust. The structure comprises a roller body 1, a cover plate 2, a roller shaft 3, a disassembly structure 4, a finned structure 5, and a protective structure 6. These components work together to achieve timely heat dissipation and removal from inside the roller.
[0034] like Figures 1-6As shown, embodiments of this utility model provide a powder roller heat dissipation structure, such as... Figure 1 and Figure 2 As shown, the roller body 1 is a hollow structure with milled end faces. Annular baffles 11 are welded to both end faces of the roller body 1. Figure 2 and Figure 6 As shown, the cover plate 2 has a circular structure, and an annular plate 21 with an inner diameter adapted to the annular baffle 11 is fixedly connected to one side, which can seal the cover plate 2 and the roller body 1. Figure 1 and Figure 2 As shown, a disassembly and assembly structure 4 for disassembling and assembling the cover plate 2 and the annular baffle 11 is provided between the cover plate 2 and the annular baffle 11, such as... Figures 1-4 As shown, a finned structure 5 for heat conduction and dissipation inside the roller body 1 is provided between the cover plate 2 and the annular baffle 11. Heat dissipation fins 52, inserted into the first rectangular slot 51 on the annular baffle 11 and the second rectangular slot 53 on the cover plate 2, dissipate heat inside the roller body 1. The principle is to increase the heat conduction area, thereby increasing the heat dissipation effect. Figure 1 As shown, the protective structure 6 installed on one side of the cover plate 2 can protect one side of the cover plate 2, mainly serving the purpose of dust prevention.
[0035] By fixing the fin structure 5 to the cover plate 2 and the annular baffle 11 through the disassembly and assembly structure 4, it can be installed with the roller body 1. At this time, under the action of the heat dissipation fin plate 52, the heat inside the roller body 1 can be quickly conducted and dissipated, thereby improving the overall heat dissipation effect.
[0036] like Figure 1 and Figure 2 As shown, the disassembly and assembly structure 4 includes a first screw hole 41, which is opened on one side of the annular baffle 11. There are four first screw holes 41, which are equidistantly arranged around one side of the annular baffle 11. A second screw hole 42 is opened on one side of the cover plate 2. The inner walls of the first screw hole 41 and the second screw hole 42 are threaded with a first threaded clamp 43. After the first screw hole 41 and the second screw hole 42 are manually adjusted and aligned, the first threaded clamp 43 can be rotated and inserted, thereby rigidly connecting the cover plate 2 and the roller body 1.
[0037] like Figure 4 As shown, a rectangular baffle 55 is fixedly connected to the outer surface of the heat dissipation fin 52 by welding. At this time, the rectangular baffle 55 can limit the heat dissipation fin 52 so that it fits and limits the cover plate 2.
[0038] like Figure 4As shown, a third screw hole 56 is provided on one side of the rectangular baffle 55. The number of rectangular baffles 55 and third screw holes 56 is the same, and both are the same as the number of heat dissipation fins 52. Four fourth screw holes 57 are provided on one side of the cover plate 2. The four fourth screw holes 57 are wrapped around one side of the cover plate 2. The inner walls of the third screw holes 56 and fourth screw holes 57 are threaded with second threaded rods 54. The second threaded rods 54 can be fixed with the third screw holes 56 and fourth screw holes 57, so that the cover plate 2 is rigidly connected to the rectangular baffle 55.
[0039] like Figure 5 As shown, a heat dissipation plate 22 is provided on one side of the cover plate 2. The heat dissipation plate 22 is a traditional heat dissipation method of the roller body 1. It is directly connected to the outside through the roller body 1, thereby achieving the heat dissipation effect. A roller shaft 3 is fixedly connected to one side of the cover plate 2. The roller shaft 3 is one of the conventional components of the pressure roller.
[0040] like Figure 5 and Figure 6 As shown, the protective structure 6 includes a vertical ring plate 61 and a circular filter plate 63. One side of the vertical ring plate 61 is fixedly connected to one side of the cover plate 2 by welding. A horizontal ring plate 62 is fixedly connected to one side of the vertical ring plate 61 by welding. The vertical ring plate 61 and the horizontal ring plate 62 can enclose the area of the heat dissipation plate 22, so that the heat dissipation plate 22 is located between the vertical ring plate 61 and the horizontal ring plate 62. An annular clamping plate 610 is fixedly connected to one side of the circular filter plate 63. The annular clamping plate 610 engages with the inner wall of the horizontal ring plate 62. The annular clamping plate 610 can fit against the inner wall of the horizontal ring plate 62, thereby improving the sealing performance.
[0041] like Figure 5 As shown, a circular insertion hole 67 is provided on one side of the circular filter plate 63, and the roller 3 is inserted into the circular insertion hole 67. The roller 3 passes through the inside of the circular insertion hole 67, so that the installation of the circular filter plate 63 will not affect the use of the roller 3.
[0042] like Figure 5 As shown, a fifth screw hole 64 is provided on one side of the circular filter plate 63, and a sixth screw hole 65 is provided on one side of the transverse ring plate 62. The number of the fifth screw hole 64 and the sixth screw hole 65 is the same, and there are four of them. They can be manually adjusted to be aligned. The inner walls of the fifth screw hole 64 and the sixth screw hole 65 are threaded with a third threaded rod 66. The third threaded rod 66 is fixed to the fifth screw hole 64 and the sixth screw hole 65, which can rigidly connect the circular filter plate 63 and the transverse ring plate 62.
[0043] like Figure 5 As shown, an annular block 68 is fixedly connected to one side of the circular filter plate 63. A rubber ring 69 is snapped into the inner wall of the annular block 68. The annular block 68 can limit the rubber ring 69, so that the rubber ring 69 can improve the sealing between the roller 3 and the circular filter plate 63.
[0044] Working principle like Figures 1-6 As shown, the heat dissipation fins 52 are first inserted into the first rectangular slot 51 and the second rectangular slot 53, and then the second threaded rod 54 is fixed to the third screw hole 56 and the fourth screw hole 57 so that the heat dissipation fins 52 can be fixed to the cover plate 2. At this time, manually align the first screw hole 41 and the second screw hole 42, and place the first threaded rod 43 inside the first screw hole 41 and the second screw hole 42, thereby fixing the cover plate 2 and the roller body 1. At this time, the heat dissipation fin plate 52 is located inside the roller body 1, thereby conducting heat to the inside. At this point, the annular clamping plate 610 is clamped to the transverse annular plate 62. The fifth screw hole 64 and the sixth screw hole 65 are aligned. The third threaded clamping rod 66 is fixed to the fifth screw hole 64 and the sixth screw hole 65. This fixes the circular filter plate 63 to the transverse annular plate 62 and prevents dust from entering the heat sink 22.
