Description

Technical Field

[0001] This utility model relates to the field of welding machine cooling technology, and more specifically, to a cooling water control mechanism. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding machines require cooling during use, and the flow of cooling water is controlled by a controller.

[0003] A search revealed that utility model patent CN205348263U discloses a circulating cooling water booster device for robotic welding machines in an automotive welding factory. It includes a circulating cooling water supply main pipe for the factory welding machines, a circulating cooling water return main pipe for the factory welding machines, multiple robotic welding machines, multiple stationary welding machines, multiple mobile welding machines, a circulating cooling water supply pipe for the robotic welding machines, and a controller. One end of the circulating cooling water supply pipe for the robotic welding machines is connected to the circulating cooling water supply main pipe for the factory welding machines, and the other end is connected to the inlets of the multiple robotic welding machines. A variable frequency booster pump is installed on the circulating cooling water supply pipe for the robotic welding machines, and the variable frequency booster pump is electrically connected to the controller. This patent applies additional pressure to the robotic welding machines on top of the total circulating cooling water supply pressure of the factory welding machines, providing the robotic welding machines with a higher water supply pressure than the other welding machines, thus balancing the water output pressure of the robotic welding machines with that of the other welding machines. It has advantages such as safety, convenient maintenance, flexible layout, and energy saving.

[0004] However, the aforementioned patent has the following shortcomings: when using a controller to control the cooling water to cool the welding machine, the controller itself also generates heat, and failing to cool it will affect the quality of the controller's control over the cooling water. Therefore, we propose a cooling water control mechanism. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cooling water control mechanism.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A cooling water control mechanism includes a control box, a controller fixedly installed in the inner cavity of the control box, a cooling mechanism provided on the control box, a sealing door hinged to the front of the control box, a fan fixedly sleeved on one side of the control box, a filter screen fixedly sleeved at the end of the fan, a filter box installed at the other end of the control box, multiple air inlets opened on the outer side of the filter box, a sealing plate hinged to the front of the filter box, and filter cotton sleeved in the inner cavity of the filter box.

[0008] As a preferred embodiment of this utility model, the cooling mechanism includes a water pump fixedly installed on the top surface of the control box cavity. The input end of the water pump extends to the top of the control box and is fixedly sleeved with a water suction pipe. The output end of the water pump is fixedly connected to a water distribution pipe. Multiple heat exchange pipes are fixedly connected to the bottom surface of the water distribution pipe.

[0009] As a preferred embodiment of this utility model, a threaded hole is provided on the other side of the control box, and an external threaded tube is provided on the side of the filter box, with the end of the external threaded tube threaded into the inner cavity of the threaded hole.

[0010] As a preferred embodiment of this utility model, the bottom surface of the control box is provided with multiple wire holes, and sealing rings are fixedly fitted into the inner cavities of the multiple wire holes respectively.

[0012] In a preferred embodiment of this utility model, the side of the filter cotton is fitted to the inner wall of the filter box.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, when the controller controls the cooling water of the welding machine, the fan extracts the heat generated by the controller in the control box cavity. At the same time, the negative pressure in the control box cavity causes the air inlet on the side of the filter box to generate suction. Air is supplied to the control box cavity through the air inlet and the filter box. Meanwhile, the filter cotton is used to clean the dust and moisture in the air so that the air flowing in the control box can cool the controller.

[0015] (2) In this utility model, the cooling water in the cooling water storage tank is introduced into the inner cavity of the water distribution pipe through the water suction pipe, and the cooling water in the water distribution pipe enters the heat exchange pipe. The cooling water in the heat exchange pipe and the temperature of the control box cavity are used for heat exchange, so as to cool the control box cavity again and cool the air entering the control box cavity, ensuring the cooling effect of the controller. It has good practicality. Attached Figure Description

[0028] In this embodiment, a filter screen 4 is used to prevent external dust from entering the control box 1 from the fan 3.

[0029] For details, please refer to Figure 1 and Figure 3 The cooling mechanism 9 includes a water pump 11 fixedly installed on the top surface of the inner cavity of the control box 1. The input end of the water pump 11 extends to the top of the control box 1 and is fixedly sleeved with a water suction pipe 17. The output end of the water pump 11 is fixedly connected to a water distribution pipe 12. Multiple heat exchange pipes 13 are fixedly connected to the bottom surface of the water distribution pipe 12. A water collection pipe 14 is fixedly connected to the bottom end of the multiple heat exchange pipes 13. A water outlet pipe 15 is fixedly connected to the bottom surface of the water collection pipe 14. The bottom end of the water outlet pipe 15 is fixedly sleeved to the bottom of the control box 1 and is fixedly sleeved with a water return pipe 16.

[0030] In this embodiment, the ends of the suction pipe 17 and the return pipe 16 are respectively connected to the cooling water storage tank, so that the cooling water can be drawn into the distribution pipe 12, the heat exchange pipe 13 and the collection pipe 14 through the suction pipe 17, and the cooling water can be returned to the cooling water storage tank through the return pipe 16.

[0031] For details, please refer to Figure 2 and Figure 5 On the other side of the control box 1, there is a threaded hole 18, and on the side of the filter box 5, there is an external threaded pipe 19, the end of which is threaded into the inner cavity of the threaded hole 18.

[0032] In this embodiment, the filter box 5 is installed on the side of the control box 1 through the cooperation of the threaded hole 18 and the external threaded pipe 19.

[0033] For details, please refer to Figure 4 The bottom surface of the control box 1 has multiple wire holes 20, and the inner cavity of each wire hole 20 is fixedly fitted with a sealing ring 21.

[0034] In this embodiment, the control connection line is connected to the controller 2 through the wire hole 20 so that the controller 2 can control the supply of welding cooling water. The sealing ring 21 is used to ensure the stability of the connection line and the sealing performance of the sealing ring 21.

[0035] For details, please refer to Figure 1 Multiple mounting bases 22 are fixedly connected to the control box 1, and each mounting base 22 is provided with mounting holes 23.

[0036] In this embodiment, the control box 1 is installed by using the mounting base 22, mounting hole 23 and screws.

[0037] For details, please refer to Figure 5 The side of the filter cotton 7 is in contact with the inner wall of the filter box 5.

[0038] In this embodiment, the filter cotton 7 is designed to completely filter the air entering the filter box 5, and at the same time absorb the moisture in the air.

[0039] Working Principle: In use, first thread the control cable through the wire hole 20 into the inner cavity of the control box 1, connecting one end of the cable to the controller 2 and the other end to the cooling water supply equipment. The controller 2 controls the cooling water supply to the welding machine. When the controller 2 operates, it generates heat. At this time, the fan 3 is activated to extract the heat from the inner cavity of the control box 1. Simultaneously, the negative pressure inside the control box 1 creates suction through the air inlet 6 on the side of the filter box 5, drawing air into the inner cavity of the filter box 5. The filter cotton 7 filters dust from the air and absorbs moisture, thus ensuring a smooth and clean environment. Clean air enters the control box 1, and the airflow in the control box 1 cools the controller 2. Finally, the controller 2 controls the water pump 11 to run, so that the suction pipe 17 guides the cooling water in the cooling water storage tank into the inner cavity of the water distribution pipe 12, and the cooling water in the water distribution pipe 12 enters the heat exchange pipe 13. The cooling water in the heat exchange pipe 13 exchanges heat with the temperature of the inner cavity of the control box 1, thereby cooling the inner cavity of the control box 1 again and cooling the air entering the inner cavity of the control box 1. The water after heat exchange is guided back to the cooling water storage tank from the water collection pipe 14, the water outlet pipe 15 and the water return pipe 16, so that the cooling water can be recycled.

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 its improved concept should be covered within the protection scope of the present utility model.
