Description

Technical Field

[0001] This utility model relates to the field of hot melt welding technology, specifically a hot melt welding machine for plastic pipes. Background Technology

[0002] Thermofusion bonding is a joining method that melts the end faces of thermoplastic materials by heating and then fuses them together under certain pressure. Its core principle is to utilize the plasticity and viscosity of plastic materials in the molten state, and by precisely controlling the temperature, pressure and time, the molecular chains of the two plastic parts can penetrate and entangle with each other, forming a strong joint after cooling.

[0003] According to the announcement number CN215283421U published on the China Patent Network, a high-heat-dissipation intelligent electromagnetic thermomelting welding machine includes a main body structure. A control mechanism is located on the front of the main body structure. The main body structure includes a temperature sensor, a fixing block in the middle of the temperature sensor, an electrical wire assembly at the bottom of the temperature sensor, a limit block on the surface of the temperature sensor, and a main board at the upper end of the temperature sensor. This high-heat-dissipation intelligent electromagnetic thermomelting welding machine can perform real-time temperature detection of the main board inside the casing through the temperature sensor, preventing the main board from overheating and burning out, thus preventing welding of pipes and requiring replacement of the main board, reducing work efficiency, increasing working time, and increasing costs. The chassis's powerful cooling fan cools the main board inside the casing to prevent overheating, which would shorten the lifespan of the device and increase the frequency of main board replacement, affecting the device's service life. It is suitable for pipe connections. However, this thermomelting welding machine has poor support; when connecting pipes via thermomelting, it can only rely on clamps to hold and limit the pipes, which may cause the pipes to tilt during thermomelting, affecting the quality of the welded product.

[0004] Therefore, it is necessary to redesign and modify the electromagnetic thermomelting welding machine to effectively prevent it from becoming unsustainable. Utility Model Content

[0027] The support assembly 2 includes a connecting cable 201. The rear side of the connecting cable 201 is connected to the front side of the welding machine body 1. A welding fixture 202 is connected to the right side of the connecting cable 201. A support frame 203 is fixedly connected to the bottom of the welding fixture 202. A connecting plate 204 is fixedly connected to both the front and rear sides of the support frame 203. A right-angle plate 205 is fixedly connected to the left side of the connecting plate 204. The right-angle plate 205 is located on the surface of the welding fixture 202. A movable sleeve 206 is provided on the surface of the right-angle plate 205. An arc-shaped plate 207 is fixedly connected to the top of the movable sleeve 206. The arc-shaped plate 207 is located on the surface of the welding fixture 202. A screw 208 is fixedly connected to the bottom of the arc-shaped plate 207. A rotating sleeve 209 is threadedly connected to the surface of the screw 208. The rotating sleeve 209 is located on the top of the connecting plate 204.

[0028] refer to Figure 4 The adjusting component 3 includes a positioning plate 301, which is located at the bottom of the connecting plate 204. The top of the positioning plate 301 and the bottom of the connecting plate 204 are both fixedly connected with teeth 302, which mesh with each other. A trapezoidal block 303 is fixedly connected to the inner side of the positioning plate 301. A trapezoidal groove 304 is provided at the bottom of the support frame 203, and the trapezoidal groove 304 is slidably connected to the trapezoidal block 303.

[0029] As a technical optimization of this utility model, by setting the adjustment component 3, the front and rear positions of the support component 2 can be adjusted, thereby improving the versatility of the support component 2.

[0030] refer to Figure 3 A handle 4 is fixedly connected to the surface of the rotating sleeve 209. The handle 4 is located at the bottom of the arc plate 207. The surface of the handle 4 is provided with anti-slip texture. A right-angle block 5 is fixedly connected to the top of the connecting plate 204. The handle 4 is located at the bottom of the right-angle block 5.

[0031] As a technical optimization of this utility model, by setting the throttle 4 and the right-angle block 5, the user can easily push the rotating sleeve 209 to rotate, thus improving the convenience of rotating the rotating sleeve 209.

[0032] refer to Figure 2 The support frame 203 has a fixed internal connection to a reinforcing block 6, which is located at the bottom of the welding fixture 202.

[0033] As a technical optimization of this utility model, by setting the reinforcing block 6, the support frame 203 can be strengthened, thereby improving the overall strength of the support frame 203.

[0034] refer to Figure 4 The front and rear sides of the support frame 203 are fixedly connected to the limiting frame 7, and the connecting plate 204 is located at the bottom of the limiting frame 7.

[0035] As a technical optimization of this utility model, by setting the limiting frame 7, the connecting plate 204 can be limited to prevent the connecting plate 204 from moving at will, thereby improving the stability of the connecting plate 204 and the arc plate 207.

[0036] refer to Figure 3 An elastic friction pad 8 is fixedly connected to the top of the arc plate 207. The elastic friction pad 8 is made of rubber.

[0037] As a technical optimization of this utility model, by setting the elastic friction pad 8, the friction between the pipe and the arc plate 207 can be increased, thereby improving the support stability of the arc plate 207.

[0038] The working principle and usage process of this utility model are as follows: During pipe support operations, the operator can stably place the pipe on top of the arc-shaped plate 207. By pushing the handle 4 to rotate, the handle 4 drives the transmission sleeve 209 to rotate synchronously. At this time, the right-angle block 5 forms a constraint, effectively eliminating radial movement that may occur during the operation of the handle 4 and the transmission sleeve 209. The sleeve 209 drives the screw 208 through a threaded transmission mechanism, causing the arc-shaped plate 207 to achieve vertical lifting and lowering. When the pipe reaches the preset support height, the operation stops, thus forming a stable vertical support system. When it is necessary to adjust the front and rear positions of the arc-shaped plate 207, first vertically pull the welding clamp. The tool 202 causes the support frame 203 to detach from the ground. Then, the positioning plate 301 is pulled down, causing the trapezoidal block 303 to disengage from the trapezoidal groove 304 of the support frame 203. This completely separates the teeth 302 on the top of the positioning plate 301 from the teeth 302 on the connecting plate 204. At this point, the connecting plate 204 can be pushed back and forth to the target position. The trapezoidal block 303 is then reinserted into the trapezoidal groove 304. Finally, the welding fixture 202 is released to bring the support frame 203 into contact with the ground. During this process, when the ground pushes the positioning plate 301 upward, the teeth 302 re-engage with the connecting plate 204, forming a reliable locking mechanism. This completes the front and rear position adjustment of the support system.

[0039] In summary, this plastic pipe hot melt welding machine uses a support component to stably support the pipe. When hot melting the pipe, it does not rely solely on clamps to hold and limit the pipe, preventing tilting during the hot melt connection and avoiding affecting the quality of the welded product. This solves the problem of difficult support.
