Description

Technical Field

[0001] This utility model relates to the field of electric blanket processing technology, and in particular to an electric blanket welding device. Background Technology

[0002] An electric blanket welding device is a specialized piece of equipment used in the production of electric blankets to weld and fix the various components (such as heating wires, insulation layers, and fabric) together. This device, through precise welding techniques, ensures the structural stability and safety of the electric blankets while improving production efficiency and product quality.

[0003] A typical electric blanket welding device consists of a welding mechanism, a sliding mechanism, and a base. Therefore, the welding mechanism is the core part of the electric blanket welding device during use. It welds the various parts of the electric blanket together using specific welding techniques (such as ultrasonic welding). The sliding mechanism is used to adjust the welding position, and the base provides stable support for the welding device to ensure the smooth progress of the welding process.

[0004] However, existing technologies have the problem of inconvenience in adjusting the spacing of the welding heads, which makes it difficult for the device to adapt to the welding needs of electric heating blankets of different sizes. When dealing with electric heating blankets of different sizes or with different welding point layouts, the position of the welding heads cannot be flexibly adjusted, resulting in reduced welding efficiency and decreased welding quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric blanket welding device, which aims to improve the problem that some existing devices cannot adjust the spacing of the welding heads, making it impossible to weld electric blankets of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electric blanket welding device includes a base, a placement mechanism on the top of the base, a support rod fixedly connected to the top of the base, and a welding mechanism on the top of the support rod.

[0008] The welding mechanism includes a connecting plate, the top of which is fixedly connected to the bottom of the support rod. A limit assembly is threadedly connected to the top of the connecting plate. Two pull handles are slidably connected to the outside of the limit assembly. Two rotating shafts are rotatably connected to the bottom of the two pull handles. A connecting rod is fixedly connected to the outside of the two rotating shafts. Multiple welding heads are rotatably connected to the front outside of the two rotating shafts. A fixing block is fixedly connected to the adjacent outside of each of the multiple welding heads. A fixing column is fixedly connected to the inside of the fixing block. A rotating rod is rotatably connected to the outside of the fixing column. A rotating column is rotatably connected to one outer side of the rotating rod. A movable rod is rotatably connected to one outer side of the rotating column.

[0009] As a further description of the above technical solution:

[0010] The limiting assembly includes two bolts, the external threads of the two bolts are connected to the top of the connecting plate on opposite sides, the top of the connecting plate has two placement slots, the external threads of the two bolts are respectively connected to the inside of the placement slots, and two washers are sleeved on the outside of the bolts, the outside of the pull handle is on the adjacent side of the outside of the two washers.

[0011] As a further description of the above technical solution:

[0012] The placement mechanism includes a support frame, the bottom of which is fixedly connected to the top of the base, i.e., the outer side near the support rod, and sliding grooves are provided on both sides of the top of the support frame;

[0013] As a further description of the above technical solution:

[0014] The sliding groove has multiple sliding blocks slidably connected inside, and the top of the multiple sliding blocks is fixedly connected to a placement plate;

[0015] As a further description of the above technical solution:

[0016] Two support plates are fixedly connected to the outer sides of the placement plate, and brackets are fixedly connected to the outer, far sides of the two support plates.

[0017] As a further description of the above technical solution:

[0018] The bottom of the bracket is fixedly connected to a support column, and an eccentric wheel is rotatably connected to the outside of the support column.

[0019] As a further description of the above technical solution:

[0020] A lever plate is fixedly connected to the outside of the eccentric wheel, that is, the side closest to the support plate, and the outside of the lever plate is on the top of the placement plate.

[0021] As a further description of the above technical solution:

[0022] When the pull handle moves upward, it causes the two rotating shafts to rotate, which in turn causes the two connecting rods to adjust their upward angle. When the pull handle is pressed down, it can press down the two connecting rods.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the welding head can be adjusted in angle and changed in position, so that the welding head can flexibly move closer to or further away from the electric heating blanket, realize a variety of welding operations, adapt to the welding needs of electric heating blankets of different sizes and shapes, and further enhance the reliability and versatility of the device.

[0025] 2. In this utility model, the eccentric force of the eccentric wheel can firmly fix the electric heating blanket on the placement plate, ensuring that the electric heating blanket will not move or shift during the welding process. This stable fixing method effectively avoids quality problems that occur during the welding process, such as weak welding or inaccurate welding position, thereby significantly improving welding efficiency and welding quality.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 and Figure 3An embodiment of this utility model is provided: an electric blanket welding device, including a base 1, a placement mechanism 2 is provided on the top of the base 1, a support rod 3 is fixedly connected to the top of the base 1, the design of which can provide good support capacity, and a welding mechanism 4 is provided on the top of the support rod 3.

[0034] The welding mechanism 4 includes a connecting plate 41, which provides stable connection capability through the support rod 3. The top of the connecting plate 41 is fixedly connected to the bottom of the support rod 3. A limit assembly is threadedly connected to the top of the connecting plate 41, which includes two bolts 43. The limit assembly is designed to provide good fixing capability. The external threads of the two bolts 43 are connected to the opposite side of the top of the connecting plate 41. Two placement slots 42 are formed on the top of the connecting plate 41, which are designed to provide good placement space so that the bolts 43 can be placed inside the placement slots 42. The external threads of the two bolts 43 are respectively threaded inside the placement slots 42. Two washers 44 are fitted around the bolt 43, designed to provide good friction. The pull handle 45 is located on the adjacent side of the two washers 44. Two pull handles 45 are slidably connected to the outside of the limiting assembly. The pull handle 45 has a rectangular groove inside, allowing the bolt 43 to be threaded into the pull handle 45 during connection. Simultaneously, the washers 44 are fixed to the outer sides of the pull handle 45. Two rotating shafts 47 are rotatably connected to the bottom of the two pull handles 45, designed to provide good rotational capability. A connecting rod 46 is fixedly connected to the outside of the two rotating shafts 47. Pulling the pull handle 45 upwards can drive... Rotating shaft 47 allows for angle adjustment of connecting rod 46. Multiple welding heads 413 are rotatably connected to the outer front sides of the two rotating shafts 47, providing excellent welding capability. When the handle 45 is pulled upwards, the rotation of the rotating shafts 47 causes the connecting rod 46 to be angled upwards, bringing the welding heads 413 closer together. Each adjacent outer side of the multiple welding heads 413 is fixedly connected to a fixing block 48, providing excellent fixing capability. A fixing post 49 is fixedly connected inside the fixing block 48, allowing the fixing post 49 to rotate smoothly. A rotating rod 410 is rotatably connected to the outside of the fixed column 49. The support provided by the fixed column 49 allows the rotating rod 410 to rotate smoothly. A rotating column 411 is rotatably connected to one side of the rotating rod 410. Its design provides good rotational capability. A movable rod 412 is rotatably connected to one side of the rotating column 411. The rotation of the rotating column 411 drives the movable rod 412 to rotate. When the welding heads 413 on both sides are brought closer together by pulling the handle 45, the movable rods 412 can be brought closer together, allowing multiple movable rods 412 to move upward, and at the same time, multiple welding heads 413 will be brought closer together.

[0035] Reference Figure 1 and Figure 4 The placement mechanism 2 includes a support frame 21, designed to provide good support. The bottom of the support frame 21 is fixedly connected to the top of the base 1, i.e., the outer side near the support rod 3. Sliding grooves 22 are formed on both sides of the top of the support frame 21, providing ample sliding space for the sliding grooves 22. Multiple sliding blocks 23 are slidably connected inside the sliding grooves 22, allowing them to slide smoothly within the grooves. A placement plate 24 is fixedly connected to the top of the multiple sliding blocks 23, providing ample placement space. Two support plates 25 are fixedly connected to the outer sides of the placement plate 24, providing good support. A bracket 26 is fixedly connected to the outer, far side of the two support plates 25, providing good support. The support plate 25 provides good support for the bracket 26. The bottom of the bracket 26 is fixedly connected to the support column 27, which is designed to provide good protection. The support column 27 is rotatably connected to the outside of the eccentric wheel 28, which is designed to provide good limiting ability. By rotating the support column 27, its convex surface can be fixed to the top of the placement plate 24 to fix the electric blanket. The outside of the eccentric wheel 28, that is, the side near the outside of the support plate 25, is fixedly connected to the actuating plate 29. By actuating the actuating plate 29, the eccentric wheel 28 can be rotated. The outside of the actuating plate 29 is on the top of the placement plate 24. When the handle 45 is pulled upward, it drives the two rotating shafts 47 to rotate, thereby driving the two connecting rods 46 to adjust the upward angle. When the handle 45 is pulled downward, it can press down the two connecting rods 46.

[0036] Working Principle: First, the electric blanket to be welded is placed on the placement plate 24. The position of the placement plate 24 is adjusted by moving the sliding block 23 within the sliding groove 22, aligning it with the welding head 413. Simultaneously, by operating the lever plate 29, the eccentric wheel 28 is rotated, adjusting the electric blanket on top of the placement plate 24. At the start of the welding operation, the operator pulls the lever 45 upwards. This upward movement of the lever 45 rotates two rotating shafts 47, causing the connecting rod 46, fixedly connected to the rotating shafts 47, to adjust its angle upwards. This action simultaneously brings the welding heads 413 on both sides closer together. Supported by the fixing block 48 and the fixing column 49, the welding heads 413 can rotate and adjust their position smoothly. When the welding heads 413 approach each other, through the linkage of the rotating column 411 and the movable rod 412, multiple welding heads 413 can simultaneously approach each other, achieving precise welding of the electric blanket and enabling different specific welding operations. During the welding process, the limiting assembly consisting of bolt 43 and washer 44 ensures the stability of the welding head 413, preventing loosening or displacement during welding. After welding is completed, the operator can push down and pull handle 45 to return the welding head 413 to its initial position for the next welding operation. This method is suitable for welding electric blankets of different sizes and shapes.

[0037] During welding, the electric blanket to be welded is placed on the placement plate 24. The placement plate 24 is connected to the sliding groove 22 on the top of the support frame 21 via multiple sliding blocks 23 on its top, allowing the placement plate 24 to slide smoothly horizontally within the sliding groove 22, thereby achieving flexible position adjustment to ensure that the electric blanket is accurately aligned with the welding head 413. When it is necessary to fix the electric blanket on the top of the placement plate 24, the operator drives the eccentric wheel 28 to rotate outside the support column 27 by turning the lever 29. The convex surface of the eccentric wheel 28 can contact the top of the placement plate 24, and the eccentric force generated by its rotation pushes the placement plate 24 up and down, thereby achieving fixation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
