Technical Field

[0001] The utility model relates to the field of plastic patching, in particular to a plastic product patching device with a hot-melt mechanism. Background Art

[0002] Plastic is a polymer compound made of monomers through addition polymerization or condensation polymerization. Its main component is resin. Plastic is very common in all walks of life due to its advantages such as light weight, high durability and low price.

[0003] However, during the use of plastic products, their length may not match the required length. At this time, for the convenience of use, it is necessary to connect the two plastic products. Usually, a plastic welding gun is used to melt the plastic at one end of the plastic product using its internal hot melt mechanism. The melted plastic is then bonded together and waited for it to cool down. The connection of the two plastic products can be completed.

[0004] When the existing patching device is used to patch two pieces of tubular plastic, since its surface is a smooth curved surface, during use, when the operator holds the welding gun to perform patching work, the position of the gun barrel and the weld is easily offset, which affects the work efficiency.

[0005] Therefore, it is necessary to provide a new plastic product patching device with a hot-melt mechanism to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a plastic product patching device with a hot-melt mechanism.

[0007] The utility model provides a plastic product patching device with a hot-melt mechanism, comprising a gun body, one end of the gun body is provided with a gun barrel, the end of the gun body close to the gun barrel is threadedly connected to a mounting ring, and two spring telescopic rods are fixedly connected to the mounting ring, the ends of the spring telescopic rods away from the gun body are fixedly connected to arc plates, long rollers are rotatably connected between the ends of the two arc plates, and the inner walls of the arc plates are provided with a plurality of rotatably connected short rollers.

[0008] Preferably, the spring telescopic rod is composed of an external telescopic rod and an internal spring, the side of the spring telescopic rod away from one end of the gun body is fixedly connected to a limiting rod, and the side of the spring telescopic rod close to one end of the gun body is rotatably connected to a fixing plate.

[0009] Preferably, the fixing plates are provided with slots, and the fixing plates are clamped on the limiting rods through the slots.

[0010] Preferably, a track is fixedly connected to one side of the gun body, a screw rod is rotatably connected in the track, and threads at both ends of the screw rod are opposite, and both ends of the screw rod are threadedly connected to a mounting rod through a seat body.

[0012] Preferably, one end of the track is rotatably connected to a knob, one end of the knob is fixedly connected to one end of the screw rod, and a plurality of anti-slip grooves are provided on the knob.

[0013] Preferably, the gun barrel is located in the mounting ring, and the length of the gun barrel is shorter than the length of the spring telescopic rod, and a button is provided on the handle.

[0014] Compared with the related art, the plastic product patching device with hot-melt mechanism provided by the utility model has the following beneficial effects:

[0015] 1. When the utility model performs patching work on tubular plastic, the arc plate is attached to the surface of the plastic product, and then the gun body is pressed to shrink the spring telescopic rod so that the gun barrel is attached to the plastic crack. Then the handle is held to move the gun body along the surface of the plastic tube. During the movement, the long roller and the short roller are used to limit and guide the gun body to prevent the position of the gun barrel and the weld from shifting. When welding, the long roller can be used to synchronously smooth the area after the hot melting of the plastic tube, which further improves the patching efficiency. At the same time, the difference between the long roller and the short roller can be used to make the device suitable for patching work of plastic tubes with different diameters.

[0016] 2. The utility model clamps the fixing plate on the limiting rod, and the spring telescopic rod can be supported at this time. Since the length of the gun barrel is shorter than the length of the spring telescopic rod, the gun barrel is pointed downward at this time, and the long roller and the spring telescopic rod are used to support and limit the gun body, which is convenient for temporary placement of the gun body.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 4 The plastic product patching device with a hot-melt mechanism provided by an embodiment of the utility model comprises a gun body 1, a gun barrel 11 is provided at one end of the gun body 1, a handle 12 is provided at the bottom of the gun body 1, and a wire 14 is fixedly connected to the bottom of the handle 12, the gun barrel 11 is located in the mounting ring 2, and the length of the gun barrel 11 is shorter than the length of the spring telescopic rod 21, and a button 13 is provided on the handle 12.

[0025] It should be noted that the gun body 1 is the main structural part of the plastic welding gun, and a hot melt mechanism is arranged inside it. When performing plastic patching work, the wire 14 is connected to the power supply, and then the operator holds the handle 12, aligns the gun barrel 11 with the plastic weld, and then presses the button 13. At this time, the hot melt mechanism inside the gun body 1 starts to work, and hot melts the plastic through the gun barrel 11. After hot melting, the hot melt area of ​​the plastic is bonded, and after waiting for its cooling area, the patching work can be completed.

[0026] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 The end of the gun body 1 close to the gun barrel 11 is threadedly connected with a mounting ring 2, and two spring telescopic rods 21 are fixedly connected to the mounting ring 2. The spring telescopic rod 21 is composed of an external telescopic rod and a built-in spring. The side of the spring telescopic rod 21 away from the end of the gun body 1 is fixedly connected to a limit rod 22. The side of the spring telescopic rod 21 close to the end of the gun body 1 is rotatably connected to a fixing plate 23. The fixing plate 23 is provided with a card slot, and the fixing plate 23 is clamped on the limit rod 22 through the card slot;

[0027] The ends of the spring telescopic rods 21 away from the gun body 1 are fixedly connected to the arc plates 3, the ends of the two arc plates 3 are rotatably connected to the long rollers 31, and the inner walls of the arc plates 3 are provided with a plurality of rotatably connected short rollers 32.

[0028] It should be noted that: when the gun body 1 is temporarily placed, the fixing plate 23 is rotated so that it is clamped on the limiting rod 22 by the card slot. At this time, the spring telescopic rod 21 is limited and fixed, and the arc plate 3 is used as a base, and the spring telescopic rod 21 is used as a bracket to temporarily support and place the gun body 1. When the gun body 1 needs to be used again, the fixing plate 23 is rotated in the opposite direction to separate it from the limiting rod 22. At this time, the spring telescopic rod 21 is released from the limit, and the spring inside it and the telescopic rod outside it cooperate to perform the contraction and reset work;

[0029] It should also be noted that: when performing plastic patching work, the arc plate 3 is first fitted on the plastic pipe, and the weld is located between the two arc plates 3. At this time, if the diameter of the plastic pipe is large, the long roller 31 will fit on the pipe wall, and if the diameter of the plastic pipe is small, the short roller 32 will fit on the pipe wall. After the operation is completed, the operator holds the handle 12 and uses the gun body 1 to press the spring telescopic rod 21. When the spring telescopic rod 21 contracts, the gun barrel 11 will contact the weld, and then the plastic on both sides of the weld of the plastic pipe is hot-melted, and the gun body 1 is controlled to move along the outer wall of the plastic pipe. During the movement, the long roller 31 or the short roller 32 that fits the pipe wall will provide guiding and limiting assistance to the gun barrel 11, so that the gun barrel 11 can move along the weld without deviation, and during the patching process, the long roller 31 can be used to synchronously smooth the plastic hot-melt area.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 A track 4 is fixedly connected to one side of the gun body 1, a screw rod 41 is rotatably connected inside the track 4, and the threads at both ends of the screw rod 41 are opposite, both ends of the screw rod 41 are threadedly connected to a mounting rod 42 through a seat body, one end of the track 4 is rotatably connected to a knob 43, one end of the knob 43 is fixedly connected to one end of the screw rod 41, and a plurality of anti-slip grooves are provided on the knob 43.

[0031] It should be noted that: when the device is used, the wire 14 is separated from the power supply, and then the wire 14 is simply wound between the two mounting rods 42, and then the knob 43 is turned to mobilize the screw rod 41 to rotate. Since the threads at both ends of the screw rod 41 are opposite, the screw rod 41 can drive the two mounting rods 42 to move away from each other when it rotates, and the mounting rods 42 can pull and straighten the wire 14 wound therebetween during the process of moving away. Then the device is placed in a tool box to improve the protection of the wire 14. When the device needs to be used, the knob 43 is used to drive the screw rod 41 to rotate in the opposite direction, so that the two mounting rods 42 are closed together. At this time, the pulling limit force of the mounting rod 42 on the wire 14 disappears, and then the wire 14 can be removed from the mounting rod 42 and connected to the power supply for subsequent plastic patching work.

[0032] The working principle of the plastic product patching device with hot-melt mechanism provided by the utility model is as follows:

[0033] First, the wire 14 is connected to the power supply, and then the operator holds the handle 12, fits the arc plate 3 on the plastic pipe, and makes the weld between the two arc plates 3. At this time, if the diameter of the plastic pipe is large, the long roller 31 will fit on the pipe wall, and if the diameter of the plastic pipe is small, the short roller 32 will fit on the pipe wall. After the operation is completed, the operator holds the handle 12 and uses the gun body 1 to press the spring telescopic rod 21, and the spring telescopic rod 21 shrinks, and the gun barrel 11 comes into contact with the weld. At this time, the button 13 is pressed, and the hot melt mechanism inside the gun body 1 starts to work, and the plastic is hot-melted through the gun barrel 11;

[0034] When hot-melting, the gun body 1 is controlled to move along the outer wall of the plastic pipe. During the movement, the long roller 31 or the short roller 32 in contact with the pipe wall will provide guiding and limiting assistance to the gun barrel 11, so that the gun barrel 11 can move along the weld without deviation. In addition, during the patching process, the long roller 31 can be used to smooth the hot-melting area of ​​the plastic synchronously, until the gun body 1 is wound around the plastic pipe for one circle, and the hot-melting patching work can be completed.

[0035] When the gun body 1 is temporarily placed, the fixing plate 23 is rotated so that it is clamped on the limiting rod 22 by the card slot. At this time, the spring telescopic rod 21 is limited and fixed, and the arc plate 3 is used as a base, and the spring telescopic rod 21 is used as a bracket to temporarily support and place the gun body 1. When the gun body 1 needs to be used again, the fixing plate 23 is rotated in the opposite direction to separate it from the limiting rod 22. At this time, the spring telescopic rod 21 is released from the limit, and the patching work can continue;

[0036] When the device is used, the wire 14 is separated from the power supply, and then the wire 14 is simply wound between the two mounting rods 42, and then the knob 43 is turned to mobilize the screw rod 41 to rotate. Since the threads at both ends of the screw rod 41 are opposite, the screw rod 41 can drive the two mounting rods 42 to move away from each other when it rotates, and the mounting rods 42 can pull and straighten the wire 14 wound therebetween during the process of moving away. Then the device is placed in a tool box to improve the protection of the wire 14. When the device needs to be used, the knob 43 is used to drive the screw rod 41 to rotate in the opposite direction, so that the two mounting rods 42 are closed together. At this time, the pulling limit force of the mounting rod 42 on the wire 14 disappears, and then the wire 14 can be removed from the mounting rod 42 and connected to the power supply for subsequent plastic patching work.
