Description

Technical Field

[0001] This utility model relates to the technical field of belt abrasive joint welding device, and in particular to an automatic belt abrasive joint welding device. Background Technology

[0002] In industrial production, sanding belts, as a highly efficient grinding tool, are widely used in metal processing, wood polishing, automobile manufacturing, and many other scenarios. In practical use, sanding belts often need to be connected into rings according to specific processing requirements, making the welding quality of the sanding belt joints a key factor affecting the overall performance of the sanding belt. To improve the welding efficiency and quality stability of sanding belt joints, an automatic sanding belt joint welding device has been developed. This device can automate the welding operation of sanding belt joints, significantly reducing errors and inefficiencies caused by manual operation.

[0003] Existing automatic welding devices for abrasive belt joints typically include a feeding mechanism, a positioning mechanism, a heating and welding mechanism, and a pressing mechanism. The technical principle is as follows: the feeding mechanism transports both ends of the abrasive belt to be welded to the designated welding position; the positioning mechanism then precisely positions the two ends of the abrasive belt to ensure joint alignment; next, the heating and welding mechanism heats the abrasive belt joint, melting the material and applying pressure. After cooling, the welding process is completed, thus achieving the connection of the abrasive belt joint.

[0004] However, in the actual operation of existing automatic welding devices for abrasive belt joints, the abrasive belts themselves become contaminated with dust during storage and transportation, and there are also certain dust particles in the working environment. This dust and particulate matter easily adhere to the abrasive belt joint during welding. During the welding process, this dust mixes into the molten material, resulting in impurities inside the welded joint. This reduces the joint's strength, making it unable to withstand the tensile force generated by the abrasive belt during operation, leading to a weak joint. Therefore, an automatic welding device for abrasive belt joints is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic welding device for abrasive belt joints, which aims to improve the problem that the poor environment and dust during welding of traditional joint welding devices reduce the strength of the joints and make them weak.

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

[0007] An automatic welding device for abrasive belt joints includes multiple support bases, a conveyor belt fixedly connected to the top of each support base, a dustproof shell fixedly connected to one side of each support base, a heating box and a bracket fixedly connected to one side of each support base, a cleaning component provided on the top of each support base, and an extrusion component provided inside the dustproof shell.

[0008] The cleaning assembly includes an air pump located on top of the support base. A bracket is fixedly connected to the outer wall of the air pump, and a collection box is fixedly connected to the bottom of the bracket. Dust baffles are fixedly connected to both sides of the collection box. A drawer is slidably connected inside the collection box. Multiple suction ports are provided on the inner side wall of the collection box. An air pipe is provided on the top of the bracket. One end of the air pipe is fixedly connected to the top of the air pump, and the other end of the air pipe is fixedly connected to an air nozzle. The air nozzle passes through the bracket and extends to the outside.

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

[0010] The extrusion assembly includes multiple push rods, which are located inside a dustproof housing, and the bottom of each push rod is fixedly connected to a bracket.

[0016] Each of the connecting rods has a sliding rod fixedly connected to its bottom, and the sliding rod is slidably connected inside the bracket.

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

[0018] The slide bar is rotatably connected to the outer wall of the threaded rod, and a slider is slidably connected inside the slide bar.

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

[0020] The slider engages with the threaded rod, and a connecting rod two is fixedly connected to the bottom of the slider.

[0022] A pressure roller is rotatably connected to the outer side wall of the second connecting rod, and a fixing ring is fixedly connected to the outer side wall of the second connecting rod, with the fixing ring fitting against the pressure roller.

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

[0024] 1. In this utility model, the air pump is started and the dust at the joint is blown away through the air nozzle. The blown-away dust is blocked by the dust baffle plate and blown into the collection box through the dust suction port. Finally, it settles into the drawer. This solves the problem that the poor environment and dust during welding of traditional joint welding devices reduce the strength of the joint and make it weak. It improves the reliability of the joint and improves the production environment.

[0025] 2. In this utility model, the start push rod pushes the pressure roller to press the sanding belt, and then the servo motor is started to make the pressure roller press back and forth at the joint. This solves the problem that the sanding belt joint becomes brittle and easy to break due to long-term heating and pressing of traditional joint welding devices, improves the production efficiency of sanding belt joint welding, and reduces the thermal damage of sanding belt welding.

[0039] Working principle: When cleaning the dust at the joint of the sanding belt, the air pump 6 is started, and the dust is blown away through the air pipe 5 and the air nozzle 7. The blown-away dust is blocked on both sides by the dust baffle 3 and falls into the collection box 23 through the dust suction port 15. Finally, it settles into the drawer 8, which achieves the effect of cleaning the dust at the joint. This solves the problem that the poor environment and dust during welding of traditional joint welding devices reduce the strength of the joint and make it weak. It improves the reliability of the joint and improves the production environment.

[0040] When the joint is reinforced by compression after hot welding, the push rod 12 is activated to drive the connecting rod 17 to press down. The connecting rod 17 drives the slide rod 16 at its bottom to press down. The slide rod 16 drives the threaded rod 19 and the slider 20 inside to press down and make the pressure roller 18 at its bottom fit tightly with the sanding belt. At this time, the servo motor 11 is activated to drive the threaded rod 19 to rotate. The rotating threaded rod 19 causes the slider 20 to slide inside the slide rod 16, thereby driving the pressure roller 18 to press back and forth at the joint. This solves the problem that the sanding belt joint becomes brittle and easy to break due to long-term heating and compression in traditional joint welding devices, improves the production efficiency of sanding belt joint welding, and reduces the heat damage of sanding belt welding.
