Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and more specifically to a negative pressure drainage bag welding machine. Background Technology

[0002] Negative pressure drainage bags are widely used medical devices, mainly used to collect and drain fluids from a patient's body. During the manufacturing process of negative pressure drainage bags, they need to be welded using a welding machine to ensure that the bags remain airtight. During the welding process, the weld joint needs to be cooled to prevent overheating and deformation.

[0003] Traditional methods of cooling the welded joints of negative pressure drainage bags involve directly impacting the welded area with water. However, when water impacts the welded joints of the drainage bag, it not only causes a lot of water to splash onto the surface of the drainage bag, but also causes the welded joints to deform due to excessive impact force, thus reducing the cooling effect of the drainage bag. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure drainage bag welding machine to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure drainage bag welding machine, comprising;

[0006] frame;

[0007] A fixing bracket is fixedly installed on the end face of the frame, and a cooling groove is provided on the end face of the fixing bracket;

[0008] A drainage bag is fixedly installed in the cooling tank, and a cover plate is fixedly installed on the top of the drainage bag;

[0009] A liquid inlet pipe that is fixedly installed on a mounting bracket and connected to the cooling tank;

[0010] Welding assembly, including at least a hot melt sheet that is slidably disposed at the top of the frame and arranged coaxially with the cooling tank.

[0011] Preferably, a hydraulic rod is fixedly installed at the top of the frame, a pressure plate is fixedly installed at the output end of the hydraulic rod, and a hot melt sheet is fixedly connected to the bottom end of the pressure plate.

[0012] Preferably, a water storage tank is fixedly installed on the end face of the frame, and a water pump is fixedly installed inside the water storage tank. The water supply end of the water pump is fixedly connected to the liquid inlet pipe.

[0013] Preferably, the fixing frame has a groove that is connected to the cooling tank. A spring arranged in a circular array is provided in the groove. A sealing block is fixedly installed on the end face of the spring, and the top of the sealing block abuts against the drainage bag.

[0014] Preferably, a drain pipe is fixedly installed in the groove, and one end of the drain pipe is fixedly connected to the water storage tank.

[0015] In the above technical solution, the negative pressure drainage bag welding machine provided by this utility model has the following beneficial effects;

[0016] This invention improves the cooling effect at the weld joint of the drainage bag by setting a fixing frame, cooling tank, drainage bag, cover plate, liquid inlet pipe, and hot melt sheet on the frame. By placing the drainage bag and cover plate into the cooling tank, the drainage bag will not shift and affect the welding effect when the hot melt sheet is welding the cover plate and drainage bag. After the drainage bag and cover plate are welded, cooling water is slowly injected into the cooling tank through the liquid inlet pipe, so that the cooling water can quickly cool down the weld joint. This not only improves the cooling efficiency of the weld joint, but also avoids the water flow impacting the weld joint and causing deformation, and also prevents water stains from forming on the drainage bag.

[0017] This invention, by incorporating a hydraulic rod and a pressure plate, facilitates the welding of the cover plate and the drainage bag.

[0018] This invention, by setting up a water storage tank and a water pump, can conveniently supply cooling water to the cooling tank to cool the welded joint between the cover plate and the drainage bag.

[0019] This invention, by incorporating a groove, a spring, and a sealing block, can prevent cooling water from flowing out of the groove during the cooling process.

[0020] This invention, by incorporating a drain pipe, allows for convenient recycling of cooling water into a storage tank. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, a negative pressure drainage bag welding machine includes:

[0030] Framework 1;

[0031] A fixing bracket 6 is fixedly installed on the end face of the frame 1, and a cooling groove 4 is provided on the end face of the fixing bracket 6;

[0032] A drainage bag 7 is fixedly installed in the cooling tank 4, and a cover plate 8 is fixedly installed on the top of the drainage bag 7;

[0033] The liquid inlet pipe 10 is fixedly installed on the mounting bracket 6 and connected to the cooling tank 4;

[0034] The welding assembly includes at least a hot melt sheet 5 that is slidably disposed at the top of the frame 1 and arranged coaxially with the cooling tank 4.

[0035] Specifically, when the drainage bag 7 placed in the cooling tank 4 needs to be welded together with the cover plate 8, the hot melt sheet 5 is driven down onto the cover plate 8, so that the hot melt sheet 5 heats up and welds the cover plate 8 and the drainage bag 7 together, so that the cover plate 8 and the drainage bag 7 can be welded together quickly. After the cover plate 8 and the drainage bag 7 are welded together, water is continuously injected into the cooling tank 4 through the liquid inlet pipe 10, so that the cooling tank 4 is filled with cold water, so that the cooling water can cool the welded joint of the cover plate 8 and the drainage bag 7. When the cooling water cools the welded joint, the cooling water cannot flow out of the cooling tank 4, thus avoiding water stains splashing on the drainage bag 7. This not only improves the cooling efficiency, but also avoids the water flow impacting the welded joint and causing deformation, thus improving the cooling effect of the drainage bag 7.

[0036] In the above embodiments, by setting a fixing frame 6, a cooling tank 4, a drainage bag 7, a cover plate 8, an inlet pipe 10, and a hot melt sheet 5 on the frame 1, the cooling effect of the drainage bag 7 at the welding point can be improved. By placing the drainage bag 7 and the cover plate 8 into the cooling tank 4, the drainage bag 7 will not be displaced when the hot melt sheet 5 is welding the cover plate 8 and the drainage bag 7, thus affecting the welding effect. After the drainage bag 7 and the cover plate 8 are welded, cooling water is slowly injected into the cooling tank 4 through the inlet pipe 10, so that the cooling water can quickly cool down the welding point. This not only improves the cooling efficiency of the welding point, but also avoids the water flow impacting the welding point and causing deformation, and also prevents water stains from forming on the drainage bag 7.

[0037] As a further embodiment of this utility model, a hydraulic rod 2 is fixedly installed at the top of the frame 1, a pressure plate 3 is fixedly installed at the output end of the hydraulic rod 2, and a hot melt sheet 5 is fixedly connected to the bottom end of the pressure plate 3.

[0038] Specifically, when the cover plate 8 and the drainage bag 7 need to be welded, the hydraulic rod 2 drives the pressure plate 3 to press down, so that the pressure plate 3 can press and solidify the cover plate 8 and the drainage bag 7. The hot melt sheet 5 installed at the bottom of the pressure plate 3 generates high temperature, so that the hot melt sheet 5 can weld the cover plate 8 and the drainage bag 7. After the welding is completed, the hydraulic rod 2 pulls the pressure plate 3 upward, so that the pressure plate 3 pulls the hot melt sheet 5 away from the drainage bag 7.

[0039] As a further embodiment of this utility model, a water storage tank 9 is fixedly installed on the end face of the frame 1, and a water pump 15 is fixedly installed inside the water storage tank 9. The water supply end of the water pump 15 is fixedly connected to the liquid inlet pipe 10.

[0040] Specifically, after the cover plate 8 and the drainage bag 7 are welded together, the cooling water stored in the water storage tank 9 is pumped into the liquid inlet pipe 10 by the water pump 15, so that the liquid inlet pipe 10 injects the cooling water into the cooling tank 4, thereby enabling the welded cover plate 8 and drainage bag 7 in the cooling tank 4 to cool down quickly. The flow rate of the cooling water is controlled by the water pump 15, so that the cooling water can flow into the cooling tank 4 slowly, thereby avoiding damage to the weld due to excessive water flow impact.

[0041] As another embodiment of this utility model, a groove 11 is provided in the fixing frame 6, the groove 11 is connected to the cooling tank 4, and a spring 12 arranged in a circumferential array is provided in the groove 11. A sealing block 13 is fixedly installed on the end face of the spring 12, and the top of the sealing block 13 abuts against the drainage bag 7.

[0042] Furthermore, a drain pipe 14 is fixedly installed inside the groove 11, and one end of the drain pipe 14 is fixedly connected to the water storage tank 9.

[0043] Specifically, when the drainage bag 7 is installed in the cooling tank 4, the weight of the drainage bag 7 itself provides pressure to the sealing block 13, causing the sealing block 13 to press down into the groove 11 for sealing. This prevents cooling water from flowing into the groove 11 when cooling the welded area. At the same time, the sealing block 13 also prevents cooling water from flowing onto the side wall of the drainage bag 7, preventing a large amount of water stains from forming on the drainage bag 7. After the welded area of ​​the drainage bag 7 has cooled down, the drainage bag 7 is lifted, causing the spring 12 to push the sealing block 13 out of the groove 11, thereby connecting the groove 11 with the cooling tank 4. Through the connection between the groove 11 and the cooling tank 4, the cooling water in the cooling tank 4 flows quickly into the groove 11, preventing the cooling water from flowing onto the drainage bag 7. The cooling water collected in the groove 11 is discharged back into the water storage tank 9 through the drain pipe 14, allowing the cooling water to be recycled and reused, thus saving fresh water resources.

[0044] Working principle: When the drainage bag 7 and the cover plate 8 need to be welded, the drainage bag 7 and the cover plate 8 are placed in the cooling tank 4, which limits their position. After the drainage bag 7 and the cover plate 8 are in position, the hydraulic rod 2 drives the pressure plate 3 to press down, which presses the cover plate 8 and the drainage bag 7 together. The pressure plate 3 then drives the hot melt sheet 5 to abut against the cover plate 8 and the drainage bag 7, welding them together. After the cover plate 8 and the drainage bag 7 are welded, the process is completed by... The water pump 15, in conjunction with the inlet pipe 10, pumps the cooling water stored in the water storage tank 9 into the cooling tank 4, so that the cooling water can cool the welded joint, thereby improving the cooling effect of the welded joint. After the welded joint between the cover plate 8 and the drainage bag 7 has cooled down, the drainage bag 7 is pushed upward, causing the spring 12 to push the sealing block 13 out of the groove 11, so that the cooling water injected into the cooling tank 4 flows into the groove 11 for collection. The cooling water is then discharged back into the storage tank through the drain pipe 14 installed in the groove 11, so that the cooling water can be recycled and reused.

[0045] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
