Description

Technical Field

[0001] This utility model relates to the field of fixing technology, specifically to a hot-melt device for positioning plastic pipe fittings. Background Technology

[0002] The plastic pipe fitting positioning hot-melt device is a professional equipment used for the construction of plastic pipe connections.

[0003] In existing technologies, the clamping structure of plastic pipe fitting positioning hot melt devices mostly adopts a "bolt tightening type" or "manual snap-on type" design. The position of each clamping component needs to be adjusted one by one, and then fixed by rotating the bolt or pressing the snap-on. A large number of repetitive and tedious operations will significantly extend the construction cycle and affect the hot melt efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a plastic pipe fitting positioning hot-melt device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A plastic pipe fitting positioning hot-melt device includes a base plate, an electric slide table, and a hot-melt unit. A fixing device is provided on one side of the base plate. The fixing device includes a guide rail, one side of which is fixedly connected to the base plate. Two electric push rods are fixedly connected to the inner side of the guide rail. An assembly block is fixedly connected to the output end of each electric push rod. An L-shaped plate is fixedly connected to one end of each assembly block. A guide plate is fixedly connected to one side of the L-shaped plate. The interiors of the two guide plates are slidably connected to the guide rail. A clamping plate is fixedly connected to one side of each guide plate. U-shaped plates are fixedly connected to both sides of each clamping plate. An electric lifting rod is fixedly connected to one side of each U-shaped plate. A round block is fixedly connected to the output end of the electric lifting rod, and a clamping block is fixedly connected to one end of the round block.

[0006] The above components achieve the following effects: the electric push rod starts and drives the assembly block to move, causing the L-shaped plate to move the guide plate, the clamping plate to move synchronously, causing the clamping plate to move the U-shaped plate, and the electric lifting rod starts and drives the round block to move, causing the clamping block to move away from or towards the clamping plate.

[0007] Preferably, two limiting strips are fixedly connected to the inner side of the U-shaped plate.

[0008] The effect achieved by the above components is to fix the limiting strip to the U-shaped plate.

[0009] Preferably, an L-shaped sliding plate is fixedly connected to one side of the guide plate.

[0010] The effect achieved by the above components is that the movement of the guide plate drives the L-shaped sliding plate to move synchronously.

[0011] Preferably, the two L-shaped sliding plates are externally slidably connected to an inner groove plate, and one side of the inner groove plate is fixedly connected to the base plate.

[0012] The effect achieved by the above components is that the L-shaped slide plate moves and slides on the inner groove plate.

[0013] Preferably, a lifting device is provided on one side of the base plate. The lifting device includes two fixing blocks. One side of the two fixing blocks is fixedly connected to the base plate, and a round rod is fixedly connected to the side of the two fixing blocks that are far apart from each other.

[0014] The effect achieved by the above components is that the round rod is fixed on the fixing block, and the fixing block is fixed on the base plate.

[0015] Preferably, a stop plate is fixedly connected to one side of the fixing block, and a slot is fixedly connected to one side of the stop plate.

[0016] The aforementioned components achieve the following effect: the slot is opened on the back plate, and the back plate is fixed on the fixing block.

[0017] Preferably, the circular rod has a collar rotatably connected to its arc surface.

[0018] The effect achieved by the above components is that the collar and the round rod are compatible.

[0019] Preferably, a handle is fixedly connected to the arc surface of the two collars, and the cross-section of the handle is U-shaped.

[0020] The effect achieved by the above components is that the handle is fixed on the collar and rotates around the collar when subjected to force.

[0021] Preferably, the arc surface of the handle is fixedly connected with an anti-slip sleeve, which is made of rubber.

[0022] The effect achieved by the above components is to increase friction by preventing slippage.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: With the fixing device, when it is necessary to position and heat-melt plastic pipe fittings, the plastic pipe fittings are positioned and clamped between the clamping block and the clamping plate. The heat fusion is completed by the heat fusion machine, and then the fittings are removed from the heat fusion machine. The electric push rod outputs the fittings so that the heat-melting end faces of the two plastic pipe fittings make precise contact and complete the reliable connection of the heat-melting end faces. The fixing device solves the problem that the clamping structure of traditional plastic pipe fitting positioning heat fusion devices mostly adopts the "bolt tightening type" or "manual buckle type" design. The clamping components need to be adjusted one by one, and then fixed by rotating the bolts or pressing the buckles. The large number of repetitive and tedious operations will significantly extend the construction cycle and affect the heat fusion efficiency.

[0024] When the hot melt device needs to be moved, the handle is held and a pulling force is continuously applied. This pulling force is transmitted to the collar through the handle, causing the collar to rotate around the rod until the handle is engaged in the preset slot on the stop plate. At this point, the handle position is firmly fixed. Continue to apply force to achieve smooth movement of the entire device. The lifting device solves the problem that traditional plastic pipe positioning hot melt devices have few external force points, making them inconvenient to move. Attached Figure Description

[0029] The following section will explain the specific setup and function of its fixing device 2 and lifting device 3.

[0030] Reference Figure 2 and Figure 3 As shown in this embodiment: the fixing device 2 includes a guide rail 201, one side of the guide rail 201 is fixedly connected to the base plate 1, two electric push rods 202 are fixedly connected to the inner side of the guide rail 201, an assembly block 203 is fixedly connected to the output end of the electric push rod 202, an L-shaped plate 204 is fixedly connected to one end of the assembly block 203, a guide plate 205 is fixedly connected to one side of the L-shaped plate 204, the interior of the two guide plates 205 is slidably connected to the guide rail 201, a clamping plate 206 is fixedly connected to one side of the guide plate 205, a U-shaped plate 207 is fixedly connected to both sides of the clamping plate 206, an electric lifting rod 208 is fixedly connected to one side of the U-shaped plate 207, a round block 209 is fixedly connected to the output end of the electric lifting rod 208, and a clamping block 210 is fixedly connected to one end of the round block 209. The system achieves the effect of the electric push rod 202 driving the assembly block 203 to move, causing the L-shaped plate 204 to move the guide plate 205, and the clamping plate 206 to move synchronously, causing the clamping plate 206 to move the U-shaped plate 207. The electric lifting rod 208 then drives the circular block 209 to move, causing the clamping block 210 to move away from or towards the clamping plate 206. Two limiting strips 211 are fixedly connected to the inner side of the U-shaped plate 207, ensuring the limiting strips 211 are fixed to the U-shaped plate 207. An L-shaped sliding plate 212 is fixedly connected to one side of the guide plate 205, ensuring the guide plate 205 moves synchronously with the L-shaped sliding plate 212. An inner groove plate 213 is slidably connected to the outside of the two L-shaped sliding plates 212, and one side of the inner groove plate 213 is fixedly connected to the base plate 1, ensuring the L-shaped sliding plates 212 slide on the inner groove plate 213.

[0031] Reference Figure 4As shown in this embodiment: the lifting device 3 includes two fixing blocks 31. One side of each fixing block 31 is fixedly connected to the base plate 1, and a round rod 32 is fixedly connected to the side of each fixing block 31 that is far apart from each other. This achieves the effect that the round rod 32 is fixed to the fixing block 31, and the fixing block 31 is fixed to the base plate 1. A stop plate 34 is fixedly connected to one side of the fixing block 31, and a slot 35 is fixedly connected to one side of the stop plate 34. This achieves the effect that the slot 35 is opened on the stop plate 34, and the stop plate 34 is fixed to the fixing block 31.

The handle 36 has an anti-slip sleeve 37 fixedly connected to its arc surface. The anti-slip sleeve 37 is made of rubber. This achieves the effect of increasing friction.

[0032] Working principle: When positioning and heat-melting plastic pipe fittings is required, the operator first connects the electric push rod 202, electric lifting rod 208, and electric slide table 4 to the controller via the fixing device 2. The controller controls the actions of each actuator. The controller starts the electric lifting rod 208, causing its output end to retract, which drives the round block 209 and clamping block 210 to move away from the clamping plate 206 until the clamping block 210 abuts against the U-shaped plate 207. The controller then automatically stops the electric lifting rod 208. Subsequently, the two plastic pipe fittings to be heat-melted are placed on the clamping plate 206, so that... The plastic pipe fitting is positioned in the clamping area between the clamping plate 206 and the clamping block 210. Next, the controller restarts the electric lifting rod 208, causing its output end to extend and drive the circular block 209 to move, thereby pushing the clamping block 210 closer to the plastic pipe fitting until the clamping block 210 and the plastic pipe fitting are tightly fitted, completing the precise positioning and stable clamping of the plastic pipe fitting. During this process, the clamping block 210, under the limiting action of the limiting strip 211, can effectively avoid applying excessive clamping force to the plastic pipe fitting, preventing deformation. After the pipe fitting is clamped and positioned, the controller starts the hot melt machine 5 to heat the two plastic pipe fittings. The connecting end faces of the pipe fittings are heated. After the heat fusion reaches the specified time, the controller activates the electric push rod 202, causing its output end to retract. This drives the assembly block 203 to move along the guide rail 201, which in turn moves the L-shaped plate 204 and the guide plate 205. This causes the clamping plate 206 and the clamped plastic pipe fittings to move away from the heat fusion device 5, safely separating the heat fusion device 5 from the plastic pipe fittings. Subsequently, the controller activates the electric slide table 4, moving the heat fusion device 5 away from the two plastic pipe fittings, thus creating sufficient contact space between the end faces of the two plastic pipe fittings. Finally, the controller activates the electric slide table 4 again. The push rod 202 extends its output end, and the L-shaped plate 204 drives the clamping plate 206 and the plastic pipe to move synchronously, so that the heat-melting end faces of the two plastic pipes make precise contact, complete the reliable connection of the heat-melting end faces, and realize the stable connection of the two plastic pipes. Through the fixing device 2, the problem of the traditional plastic pipe positioning heat melting device's clamping structure mostly adopting "bolt tightening type" or "manual buckle type" design is solved. The position of the clamping components needs to be adjusted one by one, and then fixed by rotating the bolt or pressing the buckle. A large number of repetitive and tedious operations will significantly extend the construction cycle and affect the heat melting efficiency.

[0033] When the hot melt device needs to be moved using the lifting device 3, the operator first holds the anti-slip sleeve 37 and applies a pulling force. This pulling force is transmitted to the collar 33 through the handle 36, causing the collar 33 to rotate around the round rod 32 until the handle 36 is engaged in the preset slot 35 on the abutment plate 34. At this time, the position of the handle 36 is firmly fixed. Then, the operator continues to hold the anti-slip sleeve 37 and apply a pulling force. The applied pulling force is transmitted sequentially through the handle 36, the collar 33, and the round block 209 to the fixing block 31. Finally, the fixing block 31 transmits the pulling force to the base plate 1, thereby achieving smooth movement of the entire device. The lifting device 3 solves the problem that traditional plastic pipe positioning hot melt devices have few external force points, making them inconvenient to move.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
