Description

Technical Field

[0001] The utility model relates to the field of rubber machinery, in particular to a post-calendering cooling device for rubber. Background Art

[0002] After the rubber calendering process is completed, the cooling of the rubber sheet is indeed crucial. The cooling process not only affects the subsequent processing quality of the rubber sheet, but also directly relates to the final performance and service life of the product. At present, the industry mainly uses two methods for cooling: cooling rollers and cooling water tanks. Although the cooling roller system has a stable cooling effect, the equipment investment is relatively high. Relatively speaking, the cooling water tank has a lower cost and flexible operation, so it is widely favored.

[0003] However, there are some problems with the traditional cooling method using a cooling water tank. First of all, when the hot rubber sheet is directly introduced into the water tank, it is very easy to cause water pollution. After cooling, the impurities in the water often adhere to the surface of the rubber sheet, which may damage the rubber sheet during winding and reduce the product quality.

[0004] Secondly, it is difficult to accurately control the cooling time of the rubber sheet in the water tank. An overly long cooling time may cause the rubber product to become overly hardened and even crack; while an overly short cooling time may result in the rubber sheet not being sufficiently cooled, failing to achieve the expected cooling effect, and thus affecting the subsequent processing and use of the product. Summary of the Utility Model

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a post-calendering cooling device for rubber, which is used to solve the problems in the prior art that impurities in the water adhere to the surface of the rubber sheet after cooling through the water tank, and the cooling time of the rubber sheet in the water tank is difficult to control.

[0041] Such as Figures 1-4As shown, the present utility model provides a cooling device for rubber after calendering, including a water tank 1. On two opposite sides at one end of the water tank 1, there are transmission roller frames 11. On the transmission roller frames 11, there are transmission rollers 2, and the transmission rollers 2 are used to smoothly transmit the hot rubber sheet into the water tank 1. Further, on the inner wall of the water tank 1, there are a pair of oppositely arranged limiting grooves 13, and in each limiting groove 13, there is an adjusting component 3 for adjusting the water entry depth of the rubber sheet. Specifically, the adjusting component 3 includes: a lifting block 31, a spring 32, a spring fixing seat 33, and an adjusting bolt 34. Among them, the lifting block 31 fits with the limiting groove 13 and can move up and down along the limiting groove 13. The top of the lifting block 31 is connected to the spring fixing seat 33 through the spring 32. The top of the spring fixing seat 33 is connected with an adjusting bolt 34, and one end of the adjusting bolt 34 passes through the limiting groove 13 and is threadedly connected to the top of the limiting groove 13. Further, a guiding roller 7 is connected between the lifting blocks 31 on both sides, and the stability and uniformity of the rubber sheet during the cooling process are ensured through the guiding roller 7. By adjusting the adjusting bolt 34, the compression degree of the spring can be changed, and then the position of the lifting block 31 can be controlled. The guiding roller 7 between the lifting blocks 31 is used to support and guide the rubber sheet. By changing the height of the guiding roller 7, the depth of the rubber sheet in the water can be changed, and then the cooling time of the rubber sheet in the water tank can be controlled.

[0042] In one embodiment, at one end of the water tank 1, there is a brush roller frame 12, and the brush roller frame 12 is arranged opposite to the transmission roller frame 11. On the brush roller frame 12, there is a brush roller 6. After the rubber sheet is cooled in the water tank 1, some impurities in the cooling water or tiny particles generated during the cooling process may adhere to its surface. By brushing the surface of the rubber sheet with the brush roller 6, these attachments can be effectively removed, ensuring the cleanliness of the rubber sheet surface. In addition, the brush roller 6 also helps to reduce the moisture on the surface of the rubber sheet, thereby shortening the drying time.

[0043] In order to further reduce the impurities in the cooling water adhering to the surface of the rubber sheet after cooling and provide a circulating cooling water source for the water tank 1, in one embodiment, a spraying device 5 is arranged above the water tank 1. The spraying device 5 is located between the brush roller and the guiding roller 7 both horizontally and vertically, ensuring that the spraying water effectively cleans the rubber sheet just out of the water tank 1.

[0044] Combined with Figure 1 , Figure 5, to prevent impurities in the water from accumulating between the guide roller 7 and the rubber sheet. In one embodiment, a stirring assembly 4 is provided on the water tank 1. The stirring assembly 4 includes: a movable cover plate 41 and a stirring fan 42. The movable cover plate 41 is clamped on the upper side wall of the water tank 1 and can move along the side wall of the water tank 1. A plurality of stirring fan blades 42 are connected below the movable cover plate 41 through a connecting rod 43. When the stirring fan 42 starts to work, it will rotate and push the cooling water in the water tank 1 to flow. Thus, it effectively prevents impurities from accumulating between the guide roller 7 and the rubber sheet, and at the same time helps to evenly distribute the temperature in the cooling water and improve the cooling effect.

[0045] The bottom of the water tank 1 is inclined, and a sewage outlet 15 is provided at the lower end of the bottom.

[0046] In one embodiment, an overflow prevention outlet 14 is provided on one side of the water tank 1. The horizontal height of the overflow prevention outlet 14 is higher than the top of the limit groove 13. The overflow prevention outlet 14 is connected to an external water storage device. The overflow prevention outlet 14 is used to prevent the water tank 1 from overflowing due to various reasons (such as excessive water inflow, poor drainage, etc.) during the cooling process. When the water level in the water tank 1 exceeds the preset safety line, the excess water will flow out through the overflow prevention outlet 14, thus preventing the water from overflowing the water tank 1 and protecting the surrounding equipment and environment from damage.

[0047] In summary, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0048] The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model.
