Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, and in particular to a vulcanizing machine hot plate cooling device. Background Technology

[0002] A vulcanizing machine is an industrial equipment used for vulcanizing rubber and plastic products. It has functions such as timed mold locking and automatic temperature control, and is mainly divided into three types: electric heating, steam heating and heat transfer oil heating.

[0003] In the vulcanizing machine production process, the cooling efficiency of the hot plate directly affects product quality and production rhythm. The temperature uniformity of the cooling medium (such as cooling water) is a key factor in determining the cooling effect. In existing vulcanizing machine hot plate cooling devices, the cooling medium is usually stored in a fixed box and circulated to the hot plate for heat exchange by a pump. However, such devices generally lack an effective cooling medium stirring mechanism, resulting in a lower temperature in the area near the cooling components and a higher temperature in the area far from the cooling components. This makes the temperature of the cooling medium entering the circulation system unstable, directly affecting the consistency of the hot plate cooling efficiency and making it impractical. Therefore, it is necessary to redesign a vulcanizing machine hot plate cooling device to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hot plate cooling device for a vulcanizing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vulcanizing machine hot plate cooling device includes a base plate, a cooling box fixedly installed on the upper surface of the base plate, a cooler fixedly installed on the outer wall of the cooling box, the cold end of the cooler extending into the interior of the cooling box, a rotating shaft rotatably installed inside the cooling box, a motor connected to the rotating shaft fixedly installed on the outer wall of the cooling box, multiple stirring blades fixedly installed on the outer wall of the rotating shaft via a mounting sleeve, a circulating pump fixedly installed on the outer wall of the cooling box via a support mechanism, the inlet pipe of the circulating pump extending into the interior of the cooling box, a connecting pipe fixedly installed on the outer wall of the circulating pump outlet pipe via a fixed joint, a cooling pipe fixedly installed on the outer wall of the connecting pipe, a return pipe fixedly installed on the bottom wall of the cooling pipe, and a drain pipe communicating with the interior of the cooling box fixedly installed on the outer wall of the cooling box.

[0007] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the cooling tank, and the circulation pump is fixedly installed on the upper end face of the support plate.

[0008] Preferably, the upper end face of the cooling box is fixedly installed with a return channel and a filling channel that communicate with the interior, and the return pipe extends into the interior of the return channel.

[0009] Preferably, limit plates are fixedly installed on the inner walls of both sides of the filling channel, and filter plates are slidably installed on the upper surfaces of the two limit plates.

[0010] Preferably, a controller is fixedly installed on the outer wall of the cooling box, and the controller is electrically connected to the cooler, the motor and the circulating pump.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting up components such as a rotating shaft, mounting sleeve, and stirring blades, the cooling medium in the cooling box can be fully and evenly stirred. The high-temperature reflux medium can be quickly integrated with the low-temperature medium to avoid temperature stratification. It can also allow the cold energy of the refrigerator to spread rapidly, ensuring the stability of the medium temperature, guaranteeing its cooling capacity, improving the consistency of the hot plate cooling efficiency, and enhancing the practicality of the device.

[0013] 2. By setting up components such as a filling channel, a limiting plate, and a filter plate, the filter plate can effectively filter the added medium when adding cooling medium to the cooling tank, intercepting impurities and preventing impurities from entering the cooling system and causing pipeline blockage, thus ensuring the smooth operation of the device. Moreover, the filter plate is slidably installed on the limiting plate, making it easy to remove for cleaning or replacement periodically. The operation is simple and convenient, which helps to maintain the stability of the filtration effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 A vulcanizing machine hot plate cooling device includes a base plate 1, a cooling box 2 fixedly installed on the upper surface of the base plate 1, a cooler 3 fixedly installed on the outer wall of the cooling box 2, the cold end of the cooler 3 extending into the interior of the cooling box 2, a rotating shaft 4 rotatably installed inside the cooling box 2, a motor 5 connected to the rotating shaft 4 fixedly installed on the outer wall of the cooling box 2, multiple stirring blades 7 fixedly installed on the outer wall of the rotating shaft 4 via an mounting sleeve 6, a circulating pump 9 fixedly installed on the outer wall of the cooling box 2 via a support mechanism, the inlet pipe of the circulating pump 9 extending into the interior of the cooling box 2, a connecting pipe 11 fixedly installed on the outer wall of the outlet pipe of the circulating pump 9 via a fixed joint 10, a cooling pipe 12 fixedly installed on the outer wall of the connecting pipe 11, a return pipe 13 fixedly installed on the bottom wall of the cooling pipe 12, and a drain pipe 18 communicating with the interior fixedly installed on the outer wall of the cooling box 2.

[0022] Furthermore, the cooling pipe 12 can be bent and arranged according to the shape of the hot plate of the vulcanizing machine to ensure full contact with the hot plate and improve cooling efficiency. A valve can be installed on the drain pipe 18 to facilitate control of the drain timing and avoid the accumulation of impurities in the cooling box 2, which would affect the cooling effect.

[0023] The support mechanism includes a support plate 8 fixedly installed on the outer wall of the cooling box 2, and a circulation pump 9 fixedly installed on the upper end face of the support plate 8.

[0024] Furthermore, the connection between the support plate 8 and the cooling box 2 can be fixed by welding to ensure the connection strength and prevent the support plate 8 from loosening due to vibration generated when the circulating pump 9 is working. At the same time, the size of the support plate 8 can be designed according to the size of the circulating pump 9 to ensure that the circulating pump 9 is placed stably.

[0025] The upper end face of the cooling box 2 is fixedly installed with a return channel 14 and a filling channel 15 that communicate with the interior, and the return pipe 13 extends into the interior of the return channel 14.

[0026] Furthermore, the diameter of the return channel 14 can be slightly larger than the diameter of the return pipe 13, so that the returning coolant can enter the cooling box 2 more smoothly and reduce the return resistance.

[0027] Limiting plates 16 are fixedly installed on both sides of the inner wall of the filling channel 15, and filter plates 17 are slidably installed on the upper surface of the two limiting plates 16.

[0028] Furthermore, the limiting plate 16 can provide good support and limit the filter screen plate 17, preventing the filter screen plate 17 from shifting during sliding. The mesh size of the filter screen plate 17 can be selected according to the size of the impurity particles to be filtered. The filter screen plate 17 can be easily removed from the limiting plate 16 for easy cleaning and replacement, ensuring the filtration effect.

[0029] A controller 19 is fixedly installed on the outer wall of the cooling box 2. The controller 19 is electrically connected to the refrigerator 3, the motor 5 and the circulating pump 9.

[0030] Furthermore, the controller 19 can be set with different control modes, which users can select according to actual cooling needs. At the same time, a display screen and operation buttons can be installed on the controller 19 to facilitate real-time viewing of the working status of the cooler 3, motor 5 and circulating pump 9, and to facilitate convenient operation and control of them, thereby improving the ease of use of the device.

[0031] When using this utility model, the cooling pipe 12 can be fixedly installed on the bottom wall of the hot plate. Cooling water is injected into the cooling tank 2 through the filling channel 15. The filter plate 17 filters impurities. Then, the controller 19 starts the entire cooling system. The circulation pump 9 responds immediately and draws cooling water from the cooling tank 2 through the inlet pipe. The water is then sent to the connecting pipe 11 through the outlet pipe and the fixed joint 10. Finally, the cooling water flows smoothly into the cooling pipe 12 fixed on the bottom wall of the hot plate. Since the cooling pipe 12 is in close contact with the hot plate, the high temperature of the hot plate is quickly transferred to the cooling water flowing in the pipe. After absorbing heat, the temperature of the cooling water rises. It flows along the cooling pipe 12 to the return pipe 13 and then returns to the cooling tank 2 through the return channel 14. At this time, the motor 5 starts under the command of the controller 19, which drives the rotating shaft 4 to rotate. The multiple stirring blades 7 on the mounting sleeve 6 rotate accordingly to fully stir the cooling water in the cooling tank 2.

[0032] This stirring process allows the returning high-temperature water to quickly blend with the low-temperature water inside the tank, preventing temperature stratification. At the same time, the cooler 3 starts working according to the temperature threshold set by the controller 19, releasing cold energy into the cooling tank 2 from its cold end. Under the action of the stirring blades 7, the cold energy is evenly diffused throughout the cooling tank 2, stabilizing the cooling water temperature within a suitable range. When cooling water needs to be added, it can be added through the filling channel 15. The filter plate 17 will filter impurities again. If impurities accumulate in the cooling tank 2, the valve of the drain pipe 18 can be opened for cleaning. The controller 19 monitors the operation of each component throughout the process and automatically adjusts the cooling intensity of the cooler 3, the stirring speed of the motor 5, and the flow rate of the circulating pump 9 according to the cooling requirements of the hot plate, ensuring stable and efficient hot plate cooling.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
