[0046] Reference Figure 1~Figure 4 , is an embodiment of the utility model, and proposes

[0047] A rubber strip cooling device, used for cooling the rubber strip after extrusion, comprising:

[0048] Rack 1,

[0049] The cooling tank body 2 is arranged on the rack 1, and the cooling tank body 2 has a water tank 201, and the bottom of the water tank 201 has a floating hole 202.

[0050] The pressure box 3 is arranged on the frame 1 and is located below the cooling tank body 2 . The pressure box 3 has a pressure stabilizing chamber 301 . The pressure stabilizing chamber 301 is connected to the floating hole 202 .

[0051] The present embodiment designs a cooling tank body 2 for cooling the rubber strip. When the rubber strip enters the water tank 201 of the cooling tank body 2, the pressure stabilizing chamber 301 supplies cooling liquid to the floating hole 202. The cooling liquid flowing into the floating hole 202 from the pressure stabilizing chamber 301 has a certain pressure. Under the action of the pressure, the rubber strip cannot contact the bottom of the water tank 201. Compared with the cooling device of the prior art, the rubber strip will not directly contact the cooling device, thereby avoiding the problem of rubber strip wear caused by frictional contact with the device when the rubber strip is not completely cooled, which affects the product quality. Compared with the liquid cooling device of the prior art, most of the prior art uses a static water tank to cool the rubber strip. However, after the static water tank cools the rubber strip for a period of time, the water temperature of the static water tank will change, and the main change area is the cooling position of the rubber strip. The setting of the pressure tank 3 can ensure that the liquid pressure and liquid temperature sprayed from the floating hole 202 are stable, and the cooling efficiency is stable. There will be no problem of changing the cooling efficiency of the rubber strip due to the increase in liquid temperature, which affects the product quality.

[0052] further,

[0053] The slider 4 is arranged on the cooling tank body 2 for transverse sliding. The slider 4 is located in the water tank 201. There are two sliders 4 arranged symmetrically.

[0054] The limiting member 5 is arranged on the slider 4 for lifting and sliding.

[0055] The shaping roller 6 is rotatably arranged on the limiting member 5 , and has a shaping groove 601 , and the shaping groove 601 has a shaping spray hole 602 . The shaping roller 6 is used to abut against the rubber strip, and the shaping spray hole 602 is used to face the rubber strip.

[0056] In this embodiment, a shaping roller 6 is designed to clamp the rubber strip to prevent the rubber strip from swinging in the water tank 201 when it is extruded too quickly during production. When the rubber strip swings, it may be scratched against the wall of the water tank 201. The roller surface of the shaping roller 6 can fit the outer surface of the rubber strip. During the rubber strip conveying process, the shaping spray hole 602 on the shaping roller 6 continuously sprays cooling liquid to the rubber strip. The cooling liquid sprayed by the shaping spray hole 602 can lubricate the surface of the rubber strip to prevent sticking, and can cool the rubber strip. Considering that the width and thickness of rubber strips of different specifications are different, a slider 4 is also designed to adjust the distance between the two shaping rollers 6, and a limiter 5 is designed to adjust the height of the shaping roller 6. When the pressure of the pressure stabilizing box is adjusted, the height of the rubber strip will also change compared to the bottom of the water tank 201. At this time, the height of the limiter 5 can be adjusted. Its structure is simple and suitable for cooling rubber strips of different specifications and materials during production. The simple structure is more convenient for maintenance, which is conducive to the promotion of rubber strip cooling devices.

[0057] Furthermore, it also includes

[0058] The cooling fan 7 is arranged on the frame 1 and faces the cooling tank 2.

[0059] The pump body 8 is communicated with the pressure stabilizing chamber 301 .

[0060] In this embodiment, a cooling fan 7 is designed to accelerate the cooling of the rubber strip. When the rubber strip passes through the cooling trough body 2, the cooling fan 7 blows cooling air to the rubber strip. By cooling the water on the surface of the rubber strip or blowing it to evaporate, the cooling of the rubber strip can be effectively accelerated. A pump body 8 is designed to continuously supply water to the pressure stabilizing chamber 301. The cooling fan 7 has a simple structure and effectively reduces the site requirements of the cooling device by improving the cooling efficiency.

[0061] Furthermore, it also includes

[0062] The pressure stabilizing cover 9 is arranged on the frame 1 and is located between the cooling fan 7 and the cooling tank 2. The pressure stabilizing cover 9 has cooling holes, which are used to face the top and both sides of the rubber strip.

[0063] The wind shield 10 is arranged in the pressure stabilizing cover 9 . The wind shield 10 is located between the cooling fan 7 and the cooling hole. There is a gap between the wind shield 10 and the pressure stabilizing cover 9 .

[0064] In the present embodiment, taking into account that if the cooling fan 7 blows directly on the rubber strip, the incompletely shaped rubber strip may be deformed, a pressure stabilizing hood 9 is designed. A wind shield 10 is arranged inside the pressure stabilizing hood 9. The cooling fan 7 blows directly on the wind shield 10. The cold air is diffused from the wind shield 10 to the entire pressure stabilizing hood 9 and then blown out from the cooling hole to avoid defective products caused by the cooling fan 7 blowing directly on the rubber strip. The pressure stabilizing hood 9 has a certain extension section in the direction of the rubber strip outlet 1602 of the cooling trough body 2. The extension section can dry the coolant to avoid the coolant affecting the next process. The structure is simple and easy to maintain.

[0065] Furthermore, it also includes

[0066] The fixing member 11 is slidably arranged on the limiting member 5. There are two fixing members 11. The two ends of the shaping roller 6 are respectively rotatably arranged on one fixing member 11.

[0067] The elastic member 12 has one end acting on the fixing member 11 and the other end acting on the limiting member 5, so as to provide a force for the fixing member 11 to approach the rubber strip.

[0068] In this embodiment, a fixing part 11 is designed for the installation of the shaping roller 6, and an elastic part 12 is designed to provide a force for the two shaping rollers 6 to approach each other, so as to ensure that the shaping rollers 6 can produce a continuous and stable clamping force on the rubber strip. By means of the shaping rollers 6 approaching each other, a slightly deformed rubber strip can be corrected, so as to improve the product quality of the rubber strip product.

[0069] Furthermore, a pressure sensor 13 is included. The pressure sensor 13 is arranged on the limiting member 5 , and one end of the elastic member 12 is pressed on the pressure sensor 13 .

[0070] In this embodiment, a pressure sensor 13 is designed. When the rubber strip undergoes a large deformation, the pressure sensor 13 sends a signal to alarm the operator. The setting of the pressure sensor 13 can effectively reduce the losses caused by the failure of the extruder to be discovered in time, which is beneficial for the operator to monitor the operating status of the equipment and is also beneficial to improving product quality.

[0071] Furthermore, it also includes

[0072] The cooling tank 14 is arranged on the frame 1 , the cooling tank 14 is connected to the water tank 201 , one end of the pump body 8 is connected to the cooling tank 14 , and the other end is connected to the pressure stabilizing chamber 301 .

[0073] In this embodiment, a cooling tank 14 is designed, and a cooling device is arranged outside the cooling tank 14. The liquid in the water tank 201 after cooling the rubber strip can flow into the cooling tank 14. After the liquid is cooled in the cooling tank 14, it is pumped by the pump body 8 into the pressure stabilizing chamber 301 to cool the rubber strip. The structure is simple, the coolant is recycled, the use of the coolant is reduced, and the cost is saved.

[0074] Furthermore, it also includes

[0075] The feed guide 15 is arranged on the frame 1 and is located at one end of the cooling tank body 2.

[0076] The discharging guide 16 is arranged on the frame 1 and is located at the other end of the cooling trough body 2 .

[0077] In this embodiment, in order to prevent the rubber strip from being scratched when entering or moving out of the water tank 201, an inlet guide 15 and an outlet guide 16 are designed, which have a simple structure and are easy to maintain, thereby effectively improving the product quality of the rubber strip.

[0078] Furthermore, both the feed guide 15 and the discharge guide 16 have an air cavity 1601 , and the air cavity 1601 has an outlet 1602 . There are multiple outlets 1602 , which are evenly distributed on the outer walls of the feed guide 15 and the discharge guide 16 .

[0079] In this embodiment, both the feed guide 15 and the discharge guide 16 are designed with an outlet 1602. When the cooling device is working, the outlet 1602 sprays high-pressure gas outward to prevent the rubber strip from scratching the feed guide 15 and the discharge guide 16. The outlet 1602 of the guide can also clean the residual coolant on the rubber strip, which facilitates the next process and improves product quality.

[0080] Furthermore, it also includes

[0081] The cleaning piece 17 is slidably disposed in the cooling tank 14 , and the cleaning piece 17 abuts against the tank wall of the cooling tank 14 .

[0082] In this embodiment, considering that impurities may appear in the coolant after being used for a period of time, in order to prevent the impurities from being discharged into the pressure stabilizing chamber 301 by the pump body 8, a filter element can be added on one side of the pump body 8. In order to prevent long-term accumulation of impurities, the cooling tank 14 is cleaned regularly. In order to facilitate the operation of the operator, a cleaning piece 17 is designed. When the cooling tank 14 needs to be cleaned, the cooling tank 14 can be cleaned by moving the cleaning piece 17, and the impurities can be removed by the staff, or a cleaning hole can be opened on the cooling tank 14, and the driving member can be used to drive the cleaning piece 17 to move, so that the impurities can be discharged from the cleaning hole. The structure is simple, and the labor intensity of the operator is reduced.
