[0040] Reference below Figure 1-Figure 12 The rubber roller cooling device 100 according to the embodiment of the utility model is described

[0041] like Figure 1-Figure 12 As shown, the rubber roller cooling device 100 according to the embodiment of the utility model includes: a housing 10, a cooling part 20 and a cleaning part 30.

[0042] A housing cavity 11 for accommodating the rubber roller 101 is formed in the shell 10. The cooling unit 20 is arranged in the shell 10 and is suitable for spraying cooling medium toward the rubber roller 101. The cleaning unit 30 is arranged on the downstream side of the cooling unit 20 in the rotation direction of the rubber roller 101, and is clean and suitable for removing the cooling medium on the surface of the rubber roller 101.

[0043] It should be noted that part of the rubber roller 101 extends into the accommodating cavity 11, so that after the rubber roller 101 completes the melt processing, the cooling unit 20 can spray the cooling medium on the rubber roller 101, so that the rubber roller 101 can be cooled, thereby improving the overall cooling capacity of the rubber roller 101, and the cooling unit 20 can also improve the transverse cooling uniformity of the roller surface of the rubber roller 101, thereby improving the quality of the processed sheet.

[0044] Furthermore, the rubber roller cooling device 100 is also provided with a cleaning section 30, which is located on the downstream side of the cooling section 20 in the selection direction of the rubber roller 101, so that after the rubber roller 101 is cooled by the cooling section 20, the cleaning section 30 can remove the cooling medium on the rubber roller 101, thereby avoiding the cooling medium from affecting the processing of the rubber roller 101, and further avoiding the cooling medium from affecting the quality of the sheet.

[0045] As a result, part of the rubber roller 101 will extend into the accommodating cavity 11 in the shell 10, and at the same time, the cooling part 20 in the shell 10 can spray cooling medium toward the rubber roller 101, so that the rubber roller 101 can be well cooled after processing the sheet, thereby making the overall cooling capacity of the rubber roller 101 better, and improving the lateral cooling uniformity of the roller surface of the rubber roller 101. At the same time, the rubber roller cooling device 100 is also provided with a cleaning part 30, which can remove the cooling medium on the rubber roller 101 to avoid affecting the processing of the rubber roller 101.

[0046] According to the rubber roller cooling device 100 of the embodiment of the utility model, the cooling unit 20 can spray the cooling medium on the rubber roller 101 to accelerate the cooling of the rubber roller 101, so that the rubber roller 101 can better process the sheet material. At the same time, the cleaning unit 30 can remove the cooling medium from the rubber roller 101 after the rubber roller 101 has been cooled, so that the rubber roller 101 will not be affected by the cooling medium when processing the melt, thereby improving the quality of the processed sheet material.

[0047] In some embodiments, Figure 1-Figure 3 As shown, the cooling part 20 extends in the first direction and is parallel to the rotation axis of the rubber roller 101 , and a first spray hole 21 is formed on the cooling part 20 , and the first spray hole 21 is configured as a strip hole extending in the first direction.

[0048] It should be noted that the cooling portion 20 extends in the first direction and is parallel to the rotation axis of the rubber roller 101. In this way, when the first spray hole 21 of the cooling portion 20 sprays the cooling medium on the rubber roller 101, the cooling medium can also be sprayed on the rubber roller 101 along the first direction. In this way, the rubber roller 101 is cooled more evenly. At the same time, the first spray hole 21 is constructed as a strip hole extending in the first direction. In this way, when the cooling portion 20 sprays the cooling medium on the rubber roller 101 through the first spray hole 21, it can cover the entire processing surface of the rubber roller 101 in the length direction.

[0049] Thus, the cooling portion 20 extends in the first direction and is parallel to the rotation axis of the rubber roller 101, so that the cooling medium sprayed from the first spray hole 21 of the cooling portion 20 can be sprayed on the rubber roller 101 along the first direction, thereby making the cooling of the rubber roller 101 more uniform. At the same time, the first spray hole 21 is constructed as a strip hole and extends in the first direction, so that the cooling portion 20 can cover the entire processing surface of the rubber roller 101 when spraying the cooling medium through the first spray hole 21.

[0050] In some embodiments, Figure 3-Figure 6 As shown, a fluid cavity 23 extending in a first direction is formed in the cooling portion 20, and a partition plate 22 is formed in the fluid cavity 23. The partition plate 22 divides the fluid cavity 23 into a first cavity 231 connected to the water source 51 and a second cavity 232 connected to the first spray hole 21; wherein a plurality of second spray holes 223 spaced apart from each other are formed on the partition plate 22.

[0051] It should be noted that the fluid cavity 23 formed by the cooling part 20 is connected to the water source 51, and a partition plate 22 is also formed in the fluid cavity 23, so that the cooling medium will first enter the first cavity 231 after entering the fluid cavity 23, and then enter the second cavity 232 through the second spray hole 223 and be sprayed out from the first spray hole 21 to cool the rubber roller 101.

[0052] Among them, a plurality of second spray holes 223 are formed on the partition plate 22, so that the pressure of the cooling medium can be reduced when the cooling medium enters the second cavity 232 from the first cavity 231, thereby avoiding that the pressure of the cooling medium is smaller when it is sprayed out from the first spray hole 21, and thus will not affect the surface of the rubber roller 101.

[0053] Thus, the fluid cavity 23 formed in the cooling portion 20 is connected to the water source 51, and a partition plate 22 is also provided in the fluid cavity 23, so that the cooling medium enters the first cavity 231 when entering the fluid cavity 23, and enters the second cavity 232 through the second spray hole 223 on the partition plate 22, so that it can be sprayed out through the first spray hole 21 and cool the rubber roller 101. In this way, the cooling medium can reduce its flow pressure after passing through the partition plate 22, so that the pressure of the cooling medium when spraying on the rubber roller 101 will not be too large, and will not affect the surface of the rubber roller 101.

[0054] In some embodiments, Figure 3-Figure 6 As shown, the partition plate 22 includes a first sub-plate and a second sub-plate, and the first sub-plate and the second sub-plate are inclined toward the first spray hole 21 in a direction approaching each other.

[0055] It should be noted that the first sub-plate and the second sub-plate of the partition plate 22 are inclined toward the first spray hole 21 in the direction of approaching each other, so that an angle is formed between the first sub-plate and the second sub-plate, thereby being able to play a role in buffering the water flow, that is, when the cooling medium enters the first cavity 231 and contacts the partition plate 22, the partition plate 22 formed with an angle will prevent the cooling medium from being sprayed vertically toward the first spray hole 21, but part of the cooling medium will be sprayed on the side wall of the second cavity 232, thereby making the pressure of the cooling medium sprayed from the first spray hole 21 smaller, and thus will not affect the surface of the rubber roller 101.

[0056] Thus, the first plate 221 and the second plate 222 of the partition plate 22 form a certain angle, so that the cooling medium will not be sprayed vertically to the first spray hole 21, thereby making the pressure of the cooling medium sprayed from the first spray hole 21 smaller, thereby protecting the surface of the rubber roller 101.

[0057] In some embodiments, Figure 3-Figure 6 As shown, the density of the second spray holes 223 on the partition plate 22 gradually decreases in the direction close to the free end of the partition plate 22, and / or for any two second spray holes 223 spaced apart in the extension direction of the partition plate 22, the aperture of the second spray hole 223 close to the free end of the partition plate 22 is larger than the aperture of the second spray hole 223 away from the free end of the partition plate 22.

[0058] It should be noted that one end of the partition plate 22 is close to the connection between the cooling part 20 and the water source 51, and the free end of the partition plate 22 is the end away from the connection. In this way, the density of the second spray hole 223 will gradually decrease in the direction close to the free end of the partition plate 22, so that the cooling medium near the free end of the partition plate 22 can form sufficient pressure, and then the water pressure of the cooling medium near the free end of the partition plate 22 can be kept consistent with the water pressure of the cooling medium away from the free end of the partition plate 22, so that the cooling effect of the cooling medium on the rubber roller 101 is better.

[0059] Alternatively, of the two second spray holes 223 spaced apart in the extension direction of the partition plate 22, the aperture of the second spray hole 223 near the free end of the partition plate 22 is larger than the aperture of the second spray hole 223 far from the free end of the partition plate 22. In this way, the water pressure of the cooling medium near the free end of the partition plate 22 can be kept consistent with the water pressure of the cooling medium far from the free end of the partition plate 22, thereby achieving a better cooling effect when the cooling medium cools the rubber roller 101.

[0060] In the present embodiment, the density of the second spray holes 223 on the partition plate 22 gradually decreases in the direction approaching the free end of the partition plate 22, and for any two second spray holes 223 spaced apart in the extension direction of the partition plate 22, the aperture of the second spray hole 223 near the free end of the partition plate 22 is greater than the aperture of the second spray hole 223 far from the free end of the partition plate 22. This can better ensure that the cooling medium near the free end of the partition plate 22 can form sufficient pressure, so that the water pressure of the cooling medium near the free end of the partition plate 22 can be consistent with the water pressure of the cooling medium far from the free end of the partition plate 22, thereby ensuring the cooling effect of the cooling medium on the rubber roller 101.

[0061] Therefore, by changing the density and aperture of the second spray holes 223 in different areas on the partition plate 22, it is ensured that the water pressure of the cooling medium near the free end of the partition plate 22 is consistent with the water pressure of the cooling medium away from the free end of the partition plate 22, thereby ensuring the cooling effect of the cooling medium on the rubber roller 101, so that the rubber roller 101 as a whole can be well cooled.

[0062] In some embodiments, Figure 3-Figure 6 As shown, the partition plate 22 includes a first sub-segment 224, a second sub-segment 225 and a third sub-segment 226, which are connected in sequence in a direction away from the water source 51, and a length L1 of the first sub-segment 224, a length L2 of the second sub-segment 225, a length L3 of the third sub-segment 226 and a total length L of the orifice plate satisfy L1=L3=1 / 4L, L2=1 / 2L.

[0063] It should be noted that the lengths of the first sub-segment 224, the second sub-segment 225 and the third sub-segment 226 of the partition plate 22 satisfy L1=L3=1 / 4L, L2=1 / 2L, so that the length of the second sub-segment 225 is longer, and the lengths of the first sub-segment 224 and the third sub-segment 226 are shorter, so that the second sub-segment 225 can cool the middle part of the rubber roller 101 when cooling the rubber roller 101, and at the same time, the length of the second sub-segment 225 accounts for half of the total length of the partition plate 22, so that the middle part of the rubber roller 101 can be better cooled, thereby avoiding the problem of excessive heat accumulation in the middle part of the rubber roller 101.

[0064] Furthermore, when the partition plate 22 is divided into the first sub-segment 224, the second sub-segment 225 and the third sub-segment 226, the aperture and the number of holes of the second spray holes 223 thereon are d and n, and satisfy d3<d2<d1, n1<n2<n3, so that the water pressure and flow rate of the cooling medium sprayed from the first sub-segment 224, the second sub-segment 225 and the third sub-segment 226 are the same, so that the rubber roller 101 can obtain a better cooling effect.

[0065] Therefore, the length of the second sub-segment 225 satisfies L2=1 / 2L, so that the middle part of the rubber roller 101 can be better cooled, thereby avoiding the problem of excessive heat accumulation in the middle part of the rubber roller 101. At the same time, after the partition plate 22 is divided into three sub-segments, the aperture and number of the second spray holes 223 on each sub-segment can be changed to ensure that the water pressure and flow rate of the cooling medium sprayed from each sub-segment are the same, thereby better cooling the rubber roller 101.

[0066] In some embodiments, Figure 7-Figure 8 As shown, the cleaning unit 30 includes a water removal roller 31 and a blowing member 32 .

[0067] The dewatering roller 31 can be selectively attached to the rubber roller 101, and the dewatering roller 31 is suitable for contacting the surface of the rubber roller 101. The dewatering roller 31 is arranged on the upstream side of the working surface of the rubber roller 101, and the purge member 32 is arranged on the downstream side of the dewatering roller 31. The purge member 32 is connected to the air source and is suitable for blowing toward the surface of the rubber roller 101.

[0068] It should be noted that the dewatering roller 31 can be pushed by a pneumatic cylinder or a hydraulic cylinder, so that the dewatering roller 31 can be selectively attached to the rubber roller 101. In this way, when the rubber roller 101 needs to remove the cooling medium on its surface, the dewatering roller 31 is attached to the surface of the rubber roller 101, and the dewatering roller 31 is arranged on the upstream side of the working surface of the rubber roller 101, so that after the cooling of the rubber roller 101 is completed, the dewatering roller 31 can remove the cooling medium on the rubber roller 101 to avoid the rubber roller 101 being affected during the processing. At the same time, the purge member 32 is arranged on the downstream side of the dewatering roller 31, so that the purge member 32 connected to the air source can ensure that the surface of the rubber roller 101 remains dry, that is, the dewatering roller 31 can remove most of the cooling medium on the rubber roller 101, but the surface of the rubber roller 101 will still remain wet, and the purge member 32 can make the surface of the rubber roller 101 change from wet to dry, so that the rubber roller 101 will not be affected by the cooling medium in subsequent processing.

[0069] Furthermore, the blowing member 32 can further cool the rubber roller 101 when blowing the surface of the rubber roller 101, so that the surface of the rubber roller 101 can be kept at the temperature required by the processing technology during processing, thereby improving the quality of the processed sheet.

[0070] Thus, the dewatering roller 31 can remove most of the moisture on the surface of the rubber roller 101, and the blowing member 32 can change the surface of the rubber roller 101 from wet to dry, and can further cool the rubber roller 101, so that the rubber roller 101 will not be affected by the cooling medium during the next processing.

[0071] In some embodiments, the outer side of the dewatering roller 31 is coated with a water absorbing layer.

[0072] It should be noted that in the present embodiment, the cooling medium may be water, and of course in other embodiments the cooling medium may be other liquids, and the water-absorbing layer coated on the outside of the dewatering roller 31 is a material with a certain water absorption property, so that when the dewatering roller 31 is attached to the surface of the rubber roller 101, it can better remove the moisture on the surface of the rubber roller 101, thereby making the rubber roller 101 less susceptible to the influence of water in subsequent processing.

[0073] Furthermore, the surface texture of the water-absorbing layer is relatively soft, so that when the water-removing roller 31 is attached to the surface of the rubber roller 101 , the flatness of the surface of the rubber roller 101 will not be affected, thereby not affecting the quality of the processed sheet.

[0074] Therefore, the water-absorbing layer coated on the outside of the water-removing roller 31 can better absorb the moisture on the surface of the rubber roller 101, thereby avoiding affecting the quality of the sheet.

[0075] In some embodiments, Figure 9-11As shown, the rubber roller cooling device 100 further includes: a reflux portion 40 , which is disposed in the accommodating cavity 11 and has a reflux groove 41 formed in the reflux portion 40 and located at the bottom of the rubber roller 101 .

[0076] It should be noted that the reflux portion 40 is arranged in the accommodating cavity 11 and is formed with a reflux groove 41, so that the reflux groove 41 can collect the cooling medium dripping from the rubber roller 101 and the cooling medium flowing down from the dewatering roller 31, so that there will not be too much cooling medium in the accommodating cavity 11 to affect the use of the cooling device.

[0077] Therefore, by providing the reflux portion 40 in the accommodating chamber 11 , the cooling medium in the accommodating chamber 11 can be collected, thereby avoiding excessive cooling medium in the accommodating chamber 11 , thereby ensuring normal use of the cooling device.

[0078] In some embodiments, Figure 9-11 As shown, the rubber roller cooling device 100 further includes: a reflux pipe 42 , one end of which is connected to the reflux groove 41 , and the other end of which is connected to the water source 51 .

[0079] It should be noted that the cooling medium in the reflux groove 41 can flow into the water source 51 through the reflux pipe 42, so that the cooling medium can be reused, thereby reducing the use cost of the cooling device.

[0080] Thus, the reflux pipe 42 can guide the cooling medium in the reflux groove 41 into the water source 51 so that the cooling medium can be reused, thereby reducing the use cost of the cooling device.

[0081] Furthermore, one end of the return pipe 42 connected to the return groove 41 is tilted toward the water source 51 , so that the cooling medium can flow into the water source 51 more easily through the return pipe 42 , thereby avoiding excessive accumulation of cooling medium in the accommodating chamber 11 .

[0082] In some embodiments, the water source 51 is constructed as a water tank, which is also connected to a water pump and a cooling box. The cooling medium in the water tank can be pumped into the cooling part 20 through the water pump, and the cooling box can cool the cooling medium in the water tank at the same time, that is, the cooling medium that has completed cooling the rubber roller 101 can be cooled by the cooling box, so that the cooling medium in the water tank can be maintained within a suitable temperature range, thereby better cooling the rubber roller 101.

[0083] In some embodiments, the casting roller group is composed of a steel roller and a rubber roller 101, wherein the diameter of the steel roller is D1=700mm, the diameter of the rubber roller 101 is D2=600mm, and the gap d4=5mm of the first spray hole 21 of the cooling part 20 can ensure that the water pressure of the cooling medium sprayed from the cooling part 20 is not too large or too small. At the same time, the distance between the first spray hole 21 and the rubber roller 101 is d5=50mm, so that the cooling part 20 can cool the rubber roller 101 well, and the diameter of the water removal roller 31 is D3=200mm, and the distance between the purge piece 32 and the surface of the rubber roller 101 is d6=30mm, so that the purge piece 32 can blow away the moisture on the surface of the rubber roller 101 well.
