Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to a cooling device for a three-roller calender of a capacitor rubber sealing ring, belonging to the technical field of calenders. Background Art

[0002] In the prior art, the utility model with application number 202220384876.0 discloses a calender cooling device. In order to solve the problem of the existing calender cooling device having a cooling rate that is too fast or too slow, cooling that is too fast can easily lead to a large shrinkage rate of the rubber sheet after calendering, affecting the calendering effect, and cooling that is too slow can lead to a poor cooling effect. By setting a first cooling roller group and a second cooling roller group, the calendered rubber sheet can be pre-cooled to avoid sudden cooling at too low a temperature, which can lead to a large shrinkage rate of the rubber sheet and affect the quality of the rubber sheet. At the same time, the rubber sheet can be alternately wound around the cooling rollers of the first cooling roller group and the second cooling roller group in sequence, thereby increasing the contact time between the cooling rollers and the rubber sheet, thereby improving the cooling efficiency of the rubber sheet. After pre-cooling by the cooling rollers, the rubber sheet is further cooled by the cooling box to ensure the cooling effect of the rubber sheet.

[0003] Similar to the above application, there are still some deficiencies:

[0004] During the cooling process of the rubber sheet, the surface of the rubber sheet cannot be cleaned. When passing through the cooling roller, impurities are easily pressed into the interior of the rubber sheet, affecting the quality of the rubber sheet. In addition, the cooling roller is fixed on the frame. When the rubber sheet is pulled, the rubber sheet is subjected to greater resistance, which easily causes uneven thickness of the rubber sheet.

[0005] Therefore, a three-roller calender cooling device for capacitor rubber sealing ring is designed to optimize the above problems. Utility Model Content

When the rubber sheet enters the cooling device, the surface of the rubber sheet can be cleaned to prevent impurities from being squeezed into the interior of the rubber sheet, thereby ensuring the quality of the rubber sheet. The interior of the cooling roller is hollow, and the two ends of the cooling roller are rotatably mounted on the first bracket. During the cooling process, the cooling roller rotates with the movement of the rubber sheet, reducing the resistance to the rubber sheet, avoiding uneven thickness of the rubber sheet caused by large resistance when the rubber sheet is pulled, and having higher practicality.

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a three-roll calender cooling device for a capacitor rubber sealing ring, comprising a base 1 and a chiller 2 installed on the side of the base 1. A water inlet diversion bin 3 is provided on the side of the top of the base 1 close to the chiller 2 along the length direction of the base 1. The drain outlet of the chiller 2 is connected to the interior of the water inlet diversion bin 3. A drainage confluence bin 4 is provided on the side of the top of the base 1 away from the water inlet diversion bin 3 and is parallel to the water inlet diversion bin 3. The top of the base 1 is evenly fixed between the water inlet diversion bin 3 and the drainage confluence bin 4. The first bracket 5, the top and bottom of the first bracket 5 are rotatably installed with a cooling roller 6, the interior of the cooling roller 6 is hollow, one end of the cooling roller 6 is connected to the interior of the water inlet diversion bin 3 through a pipe, and the other end of the cooling roller 6 is connected to the interior of the drainage confluence bin 4 through a pipe, and a circulating water pump 7 is installed at one end of the drainage confluence bin 4, the input end of the circulating water pump 7 is connected to the interior of the drainage confluence bin 4, and the output end of the circulating water pump 7 is connected to the water inlet of the chiller 2 through a pipe, and a cleaning mechanism 8 is provided at the top of the base 1 at the feed end.

[0025] The overall working principle: the rubber sheet after being extruded and formed by the calender first enters the interior of the cleaning mechanism 8. After being cleaned on both sides by the cleaning mechanism 8, the rubber sheet first adheres to the surface of the cooling roller 6 at the top of the first bracket 5, and then extends downward to adhere to the surface of the cooling roller 6 at the bottom of the first bracket 5, and then passes through from under the cooling roller 6 at the bottom to enter the cooling roller 6 at the top of another first bracket 5. The rubber sheet passes through the surface of multiple groups of cooling rollers 6, and the low-temperature water generated by the chiller 2 first enters the interior of the water inlet diversion bin 3, and then evenly enters the interior of the cooling roller 6. The cooling water after cooling the rubber sheet enters the interior of the drainage convergence bin 4, and finally circulates the cooled water to the interior of the chiller 2 again through the circulating water pump 7.

[0026] In this embodiment, the cleaning mechanism 8 includes a second bracket 9, a first cross bar 10, a second cross bar 12 and cleaning cotton 13. The second bracket 9 is fixed to the top of the base 1. The first cross bar 10 is fixed to the top of the second bracket 9. The second cross bar 12 is vertically slidable inside the second bracket 9. The second cross bar 12 is parallel to the first cross bar 10. Cleaning cotton 13 is provided at the bottom of the first cross bar 10 and the top of the second cross bar 12.

[0027] Local working principle: the top of the rubber sheet is attached to the cleaning cotton 13 at the bottom of the first cross bar 10, and the cleaning cotton 13 at the top of the second cross bar 12 is attached to the bottom of the rubber sheet, so the upper and lower surfaces of the rubber sheet can be cleaned at the same time during the feeding process of the rubber sheet.

[0028] In this embodiment, guide rollers 11 are rotatably mounted on both sides of the second bracket 9 , and the guide rollers 11 are located above the second crossbar 12 .

[0029] Partial working principle: The use of the guide roller 11 can guide the rubber sheet to avoid friction on the surface of the rubber sheet.

[0030] In this embodiment, vertical guide grooves 14 are vertically opened on both sides of the second bracket 9, and sliders 16 are slidably installed inside the vertical guide grooves 14. Springs 15 are installed between the bottom of the sliders 16 and the bottom ends of the vertical guide grooves 14. Two groups of sliders 16 are respectively installed at the ends of the second cross bar 12.

[0031] Partial working principle: Since the thickness of the rubber sheet is not the same, in order to adapt to the rubber sheets of different thicknesses, the second cross bar 12 can slide up and down, and the spring 15 is used to provide an upward thrust to the second cross bar 12 to ensure that the cleaning cotton 13 on the top of the second cross bar 12 can fit the bottom of the rubber sheet.

[0032] In this embodiment, third cross bars 17 are horizontally mounted on the top and bottom of the first bracket 5 , and cleaning cotton 13 is provided on the third cross bars 17 to fit the surface of the cooling roller 6 .

[0033] Partial working principle: During the cooling process, the rubber surface can be cleaned again through the cleaning cotton 13 at the top and bottom of the first bracket 5, thereby improving the cleaning effect.

[0034] In this embodiment, the surface of the cooling roller 6 is coated with a smooth coating, and the length of the cooling roller 6 is greater than the width of the rubber belt.

[0035] Partial working principle: The smooth coating on the surface of the cooling roller 6 reduces the friction between the cooling roller and the rubber sheet, thus preventing the surface of the rubber sheet from being worn.

[0036] In this embodiment, an anti-skid pad is provided at the bottom of the base 1 , and anti-skid grooves are provided at the bottom of the anti-skid pad.

[0037] Partial working principle: The provision of the anti-slip pad can ensure the placement stability of the base 1.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
