Description

Technical Field

[0001] The present invention relates to the technical field of tire preparation, and in particular to a film cooling device. Background Art

[0002] In the mixing process of rubber tire and product factories, after the rubber compound is squeezed into sheets through mixing, it first passes through a release agent pool to initially cool the sheets and is dipped in release agent to prevent the sheets from sticking together. It then enters a bellows to cool and dry, and is finally stacked into trays. After transportation and storage, it is supplied to the next process.

[0003] During this process, although the film is soaked in an isolation agent, seasonal changes have revealed that the film temperature is too high and the dryness is too low at the stacking area, making it difficult to meet process requirements. To ensure the film's cooling and drying effects and environmental protection requirements, companies need to equip high-power dust removal fans, increase the number of bellows fans, and configure cold air delivery systems, resulting in increased energy consumption and costs. Furthermore, because the rubber contains carbon black, oil, and various chemical additives, and its high discharge temperature, the rubber is extruded into sheets, generating large amounts of dust and smoke. This pollutes the environment and can even directly affect the safety of operators, significantly impacting the company's sustainable development.

[0004] At present, although a film cooling water tank device has been added to the front end of the isolation agent pool, due to the large temperature fluctuations of the water in the tank, low temperatures will cause irreversible chemical changes in the film, while excessively high temperatures will not achieve the cooling effect and cannot meet production requirements. In addition, due to limited space, the water in the film cooling water tank needs to be replaced frequently, and the film flow length is relatively short, which affects the cooling and smoke reduction effects and easily causes pollution. The height of the liquid level in the film cooling water tank and the traction of the film are achieved manually, which cannot guarantee the immersion depth of the film, and the risk of manual operation is increased. During the production process, the rubber is blocked due to excessive speed matching between the front and rear connections, which affects the operation of the equipment and increases the number of equipment failure points. In addition, the operators have to deal with the problem in a confined space, which poses a major safety hazard. Throughout the process, the cooling effect is not ideal, and the dust removal and cooling effects are not achieved. The energy-saving effect is not obvious.

[0005] Therefore, how to achieve the effect of reducing smoke, cooling and energy saving, make the film meet the process requirements, realize the automatic operation of the device and reduce manual operation is a technical problem that technicians in this field currently need to solve.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0038] As Fig. 1As shown, the film cooling device disclosed by the present application comprises a water tank, a water circulation pipeline temperature control structure, an automatic water replenishment structure and a separating agent tank; a module belt is arranged in the water tank and the separating agent tank to convey the film; the water circulation pipeline temperature control structure comprises a circulating water pump 201 and a heat exchanger 202, the heat exchanger 202 cools the water in the water tank by external cooling water, and the water circulation pipeline temperature control structure is used to maintain the constant temperature of the water in the water tank; the automatic water replenishment structure is arranged on the water tank to adjust the liquid level in the water tank.

[0039] The film cooling device provided by the present application increases the water tank at the front end of the separating agent tank, immerses the film in the water in the water tank to achieve the cooling of the film, reduces the emission of dust and smoke gas in the production process, achieves clean production and reduces the physical harm to the operators. The design of the water tank reduces the power of the rear end air bellow and the total dust removal fan, and plays an energy-saving role.

[0040] The film cooling device provided by the present application further comprises a water circulation pipeline temperature control structure and an automatic water replenishment structure, which realizes the constant temperature of the water in the water tank in the production process, realizes the automatic water replenishment of the water tank and adjusts the liquid level in the water tank. By controlling the water circulation pipeline temperature control structure and the automatic water replenishment structure, the quality and cooling effect of the film are ensured, the film meets the process requirements, the automation of the process is realized, and the labor intensity of the operators is reduced.

[0041] In order to ensure the effective immersion of the film, a press roller and a floating pressure roller are arranged on the water tank, and the film is pressed into the water in the water tank by the action of the press roller and the floating pressure roller.

[0042] In order to optimize the above technical scheme, the water tank is arranged as an upper water tank 101 and a lower water tank 102 in a superimposed manner, and the upper water tank 101 is arranged above the lower water tank 102. By arranging the upper water tank 101 and the lower water tank 102 in a superimposed manner, the floor area of the whole film cooling device is reduced, and the design of the upper and lower layers increases the water passing length of the film, greatly improving the smoke reduction and cooling effect of the water tank on the film.

[0043] In order to realize the automatic reversing of the film and reduce the working intensity of the operators in the production process, in an embodiment of the present application, a first automatic turnover structure 401 is arranged at one end of the lower water tank 102 connected with the upper water tank 101, and the first automatic turnover structure 401 can turn the film conveyed by the lower water tank 102 to the upper water tank 101. Similarly, a second automatic turnover structure 402 is arranged at one end of the separating agent tank connected with the rear end climbing transportation belt, and the film passing through the separating agent tank is turned to the rear end climbing transportation belt.

[0044] Further, the first automatic turnover structure 401 and the second automatic turnover structure 402 are provided with detection elements for detecting whether the film reaches the preset position to start or stop the first automatic turnover structure 401 and the second automatic turnover structure 402.

[0045] When the detection element on the first automatic turnover structure 401 detects the film at the preset position, the first automatic turnover structure 401 is started to automatically transition the film from the lower tank 102 to the upper tank 101, and after the detection element detects that the film transition is completed, the first automatic turnover structure 401 is stopped to restore the first automatic turnover structure 401 to the original position, avoiding that the first automatic turnover structure 401 is attached to the film for a long time, affecting the service life of the belt of the first automatic turnover structure 401 and causing the film to be deformed.

[0046] Similarly, when the detection element on the second automatic turnover structure 402 detects that the film reaches the preset position, the second automatic turnover structure 402 is started to transition the film from the upper tank 101 to the isolating agent tank, and after the detection element detects that the film transition is completed, the second automatic turnover structure 402 is stopped to restore the second automatic turnover structure 402 to the original position.

[0047] As shown in Fig. 2 The water circulation pipeline temperature control structure includes a circulating water pump 201 and a heat exchanger 202. The heat exchanger 202 is divided into a water tank internal circulating water inlet and outlet and a cooling water inlet and outlet. The heat exchange between the cooling water and the water in the water tank is used to achieve the cooling of the water in the water tank. In order to maintain the constant temperature of the water in the water tank, an electric actuator 204 is arranged on the heat exchanger 202. The opening of the electric actuator 204 is controlled to control the water inflow of the cooling water, control the heat exchange between the cooling water and the water in the water tank, and then achieve the constant temperature control of the water in the water tank. In an embodiment of the present application, a plate heat exchanger is used for the heat exchange between the cooling water and the water in the water tank, and other types of heat exchangers 202 can also be used.

[0048] Further, in order for the operator to more clearly know the temperature of the water in the water tank and better control the opening of the electric actuator 204, an upper water tank temperature detection component 205 and a lower water tank temperature detection component 206 are arranged to detect the temperature of the water in the upper water tank 101 and the lower water tank 102, respectively.

[0049] In order to avoid the damage of the water circulation pipeline temperature control structure caused by the pollution of the water in the water tank, a basket type filter 203 is arranged in the water circulation pipeline temperature control structure to filter the water in the water tank. The water circulation pipeline temperature control structure realizes the automatic temperature control of the water tank, ensures the constant temperature difference of the water passing film, guarantees the cooling effect, and improves the quality of the rubber compound.

[0050] As shown in Fig. 3As shown, the film cooling device provided by the application comprises an upper tank water supplement pipeline 301 and a lower tank water supplement pipeline 302, the electric valve of the upper tank water supplement pipeline 301 is opened when the liquid level in the upper tank 101 is lower than the preset liquid level and is closed when the liquid level in the upper tank 101 is higher than the preset liquid level, and the valve of the lower tank water supplement pipeline 302 is a manual valve which is manually controlled to be opened or closed by an operator.

[0051] Between the lower tank 102 and the upper tank 101, the film is not soaked in the water in the tank, and in order to further improve the cooling efficiency of the film, an upper tank water supplement spraying pipeline 303 is arranged to spray water to the film.

[0052] Further, an overflow pipe 304 is arranged in the upper tank 101, and when the liquid level in the upper tank 101 exceeds the preset height, the water exceeding the preset height in the upper tank 101 can flow into the lower tank 102 through the overflow pipe 304 to supplement the water in the lower tank 102. Through the arrangement of the electric valve of the upper tank water supplement pipeline 301 and the overflow pipe 304, the automatic water supplement of the upper tank 101 and the lower tank 102 can be realized.

[0053] In order to make the operator more clearly know the liquid level in the tank and better control the opening and closing of the manual valve, an upper tank liquid level detection component 305 and a lower tank liquid level detection component 306 are arranged to detect the liquid level in the upper tank 101 and the lower tank 102, respectively. The automatic water supplement structure realizes the automatic water supplement of the tank, ensures the soaking depth of the film, and reduces the manual operation.

[0054] The principle of the application will be described in detail in combination with specific application scenarios as follows:

[0055] Before starting, the water circulation system in the tank must be opened and the liquid level and temperature must be appropriate, and then the production state can be allowed, the film is conveyed to the lower tank 102 through the front end taking equipment, is transported to the rear end of the lower tank 102 through the conveying structure of the lower tank 102, in order to ensure the effective soaking of the film, the pressure roller and the floating pressure wheel are added above the chain plate belt of the conveying structure to press the film into the water in the tank. The detection element of the first automatic turnover structure 401 identifies that the film reaches the preset position, the first automatic turnover structure 401 is started to execute turnover, and the film is automatically transferred to the upper tank 101, and after the detection element detects that the film transfer is completed, the first automatic turnover structure 401 returns to the original position.

[0056] Film through the conveying structure of the upper tank 101, to the conveying structure of the release agent tank, the detection element of the second automatic turnover structure 402 identifies that the film reaches the preset position, and the second automatic turnover structure 402 performs turnover, and the film is transferred to the rear end climbing conveying belt, and the detection element identifies that the film transition is completed, and the second automatic turnover structure 402 restores to the original position. With the film being delivered to the conveying structure of the lower tank 102 by the front end taking device, the film cooling device enters the continuous production state.

[0057] In the production process, with the water running of the film, the water in the tank is evaporated and consumed. Overflow pipe 304 is arranged between upper tank 102 and lower tank 102, so that the water in upper tank 101 exceeding the preset height flows into lower tank 102, and upper tank liquid level detection component 305 and lower tank liquid level detection component 306 are designed in upper tank 102 and lower tank 102 respectively to detect the liquid level height in upper tank 101 and lower tank 102. When the film passes between lower tank 102 and upper tank 101, the upper tank supplement spray pipeline 303 is opened to spray the film. The electric valve on the upper tank water supplement pipeline 301 ensures the relative stability of the liquid level in the upper tank 101 according to the principle of low liquid level opening and high liquid level closing. In addition, the operator can manually open or close the manual valve of the lower tank water supplement pipeline 302 to adjust the liquid level height in the lower tank 102.

[0058] Similarly, with the continuous water passing of the high-temperature film, the temperature of the water in the tank is rising, and the heat exchanger 202 cools the water in the tank by cooling water. By setting upper tank temperature detection component 205 and lower tank temperature detection component 206, the temperature change in upper tank 101 and lower tank 102 is detected in real time. Based on the PID control algorithm, the system controls the opening of the electric actuator 204 on the heat exchanger 202 to control the water inlet of the cooling water and realize the constant temperature control of the water in the tank.

[0059] The whole conveying system of the film cooling device involves three transition joints between the lower tank 102, the upper tank 101, the release agent tank and the rear end climbing conveying belt, there are two automatic turnover devices, the speed between adjacent devices must be matched, the whole device has high requirements for speed matching, and a constant torque based control method is adopted on the control system to realize the constant stretching amount of the film on the front and rear conveying belts, and then ensure smooth connection.
