Technical Field

[0001] This utility model relates to the field of rubber sheet production technology, specifically a double-sided cooling device for rubber sheet production. Background Technology

[0002] Cooling is a crucial step in the production of rubber sheets. After the rubber sheets are extruded or calendered, their temperature is high and they need to be cooled to room temperature or a specific storage temperature.

[0003] The current method of single-sided cooling for rubber sheets is inefficient and the cooling process is not uniform, which can easily lead to deformation of the rubber sheets and reduce their quality and performance. Therefore, we propose a double-sided cooling device for rubber sheet production. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided cooling device for rubber sheet production, which can efficiently cool rubber sheets from both sides, while also providing more uniform cooling, avoiding deformation of the rubber sheets, and improving the quality of the rubber sheets. This solves the problems of low efficiency and uneven cooling when using single-sided cooling for rubber sheets, which can easily lead to deformation of the rubber sheets and reduce their quality and performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided cooling device for rubber sheet production, comprising a cooling box, a return water pipe, and an inlet water pipe. Several lower cooling rollers are rotatably installed at equal intervals inside the cooling box. An upper cooling roller is rotatably installed above each lower cooling roller inside the cooling box. The return water pipe and the inlet water pipe are located on opposite sides of the cooling box. Several regulating valves are fixedly connected at equal intervals to the outer surface of the inlet water pipe. Each regulating valve is fixedly connected to an inlet connecting pipe at its end. Both ends of each inlet connecting pipe are rotatably connected to one end of the corresponding upper and lower cooling rollers via inlet connectors. Several one-way valves are fixedly connected at equal intervals to the outer surface of the return water pipe. Each one-way valve is fixedly connected to a return water connecting pipe at its end. Both ends of each return water connecting pipe are rotatably connected to the other end of the corresponding upper and lower cooling rollers via return water connectors.

[0006] Preferably, both the inlet and outlet water connectors are rotary connectors.

[0007] Preferably, a rotating motor is fixedly installed on the outer surface of the cooling box near the return water pipe, and a motor gear is fixedly connected to the end of the motor output shaft. A main drive gear is fixedly installed on the outer surface of one of the upper cooling rollers and one of the lower cooling rollers near the return water pipe, and the two main drive gears mesh with each other.

[0008] Preferably, an upper rotating gear is fixedly installed on the outer surface of each upper cooling roller near the water inlet pipe, and an upper transmission gear is rotatably installed on the outer surface of the cooling box between two adjacent upper rotating gears, and the upper transmission gear and the upper rotating gear mesh with each other.

[0009] Preferably, a lower rotating gear is fixedly installed on the outer surface of each lower cooling roller near the water inlet pipe, and a lower transmission gear is rotatably installed on the outer surface of the cooling box between two adjacent lower rotating gears, and the lower transmission gear and the lower rotating gear mesh with each other.

[0010] Preferably, a support frame is fixedly installed on the lower surface of the cooling box.

[0011] Preferably, each of the upper cooling rollers and each of the lower cooling rollers is provided with a central column inside, and a number of guide plates are fixedly installed in a ring array on the outer surface of each central column at equal intervals.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves efficient double-sided cooling of rubber sheets by setting up a cooling box, upper cooling roller, lower cooling roller, water inlet pipe, regulating valve, water inlet connector, water inlet connecting pipe, return water pipe, one-way valve, and return water connecting pipe. This results in more uniform cooling, preventing deformation of the rubber sheets and improving their quality. Several upper and lower cooling rollers inside the cooling box correspond one-to-one, forming a cooling roller group. The rubber sheet passes through these groups sequentially. Cooling water is injected into each group through the water inlet pipe, and the upper and lower cooling rollers cool both sides of the rubber sheet. The heated cooling water flows away through the return water pipe. The regulating valve adjusts the flow rate of the cooling water in each cooling roller group to control the cooling speed of the rubber sheet.

[0014] 2. This utility model achieves the effect of synchronous rotation of the upper and lower cooling rollers by setting up an upper transmission gear, an upper rotating gear, a lower transmission gear, a lower rotating gear, a rotating motor, and a main transmission gear. The rotating motor drives one of the upper cooling rollers and one of the lower cooling rollers to rotate synchronously through two meshing main transmission gears. Adjacent upper cooling rollers are driven by meshing upper transmission gears and upper rotating gears, and adjacent lower cooling rollers are driven by meshing lower transmission gears and lower rotating gears.

[0015] 3. By setting a central column and a guide plate, this utility model facilitates the uniform distribution and flow of cooling water inside the upper and lower cooling rollers, thereby promoting uniform cooling of the rubber sheet. Attached Figure Description
