Technical Field
[0001] The utility model relates to the technical field of PE pipe welding, in particular to a hot melt welding device for large-diameter PE pipes. Background Art
[0002] PE is polyethylene plastic, the most basic kind of plastic. Plastic bags, food wraps, etc. are all made of PE. HDPE is a thermoplastic resin with high crystallinity and non-polarity. During the installation and use of PE pipes, it is often necessary to weld PE pipes, and thus a hot melt welding device for PE pipes is required. Hot melt welding is a method in which the ends of plastic pipes are heated and melted by an electric heating plate and then butt-jointed and fused together, and are connected together after cooling and fixing.
[0003] However, in the prior art, during the use of a hot melt welding device for PE pipes, it is necessary to butt the ports of two PE pipes. In order to ensure horizontal alignment, the two PE pipes need to be aligned. When hot melt welding large-diameter PE pipes, generally, single-position support and fixation are carried out at one end of the welding, and the stability is insufficient. During butt-joint hot melt welding, unstable situations are likely to occur, thus affecting the welding treatment of large-diameter PE pipes.
[0004] Therefore, a hot melt welding device for large-diameter PE pipes is proposed to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problems existing in the prior art.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A hot melt welding device for large-diameter PE pipes, comprising: a bottom plate and two large-diameter PE pipe bodies. One side of the top surface of the bottom plate is fixedly provided with a control terminal. A stable butt-joint assembly is arranged on the top surface of the bottom plate. Scraping assemblies are arranged on both side surfaces of the bottom plate. The stable butt-joint assembly includes a plurality of baffles. Every two of the plurality of baffles are symmetrically fixedly installed on the top surface of the bottom plate as a group. A first threaded rod is connected between the corresponding positions of each group of baffles through bearings. One side surface of two of the baffles is fixedly provided with a forward and reverse motor respectively. The output ends of the two forward and reverse motors respectively penetrate through two of the baffles and are fixedly connected to one ends of the two first threaded rods correspondingly.
[0007] As a preferred embodiment, the surfaces of the two first threaded rods are both threadedly connected with movable plates. T-shaped grooves are provided on both sides of the top surface of the bottom plate. Two L-shaped plates are fitted and slidably connected inside each of the two T-shaped grooves. Every two of the multiple L-shaped plates form a group. One end surface of each group of L-shaped plates is fixedly connected to the corresponding side surface of the two movable plates. The two movable plates and the multiple L-shaped plates move by means of the two first threaded rods and the two T-shaped grooves. V-shaped lower clamping plates are fixedly installed on the tops of the multiple L-shaped plates. Every two of the multiple V-shaped lower clamping plates form a group.
[0008] As a preferred embodiment, connection blocks are fixedly installed between each group of L-shaped plates. Vertical rods are fixedly installed on the top surfaces of the two connection blocks and the two movable plates. Slide plates are fitted and movably sleeved on the surfaces of every two of the multiple vertical rods as a group. Cross plates are fixedly installed on the bottom surfaces of the two slide plates. V-shaped upper clamping plates are fixedly installed at both ends of the bottom surfaces of the two cross plates. Every two of the multiple V-shaped upper clamping plates form a group. The two large-diameter PE pipe bodies are correspondingly clamped between each group of V-shaped lower clamping plates and each group of V-shaped upper clamping plates.
[0009] As a preferred embodiment, support plates are fixedly installed on the top surfaces of every two of the multiple vertical rods as a group. Second threaded rods are threadedly penetrated through the top surfaces of the two support plates. The bottom end surfaces of the two second threaded rods are correspondingly connected to the top surfaces of the two slide plates through bearings. Rotary disks are fixedly installed on the top end surfaces of the two second threaded rods.
[0010] As a preferred embodiment, the scraping assembly includes a U-shaped plate. The inner walls at the bottom ends of both sides of the U-shaped plate are fixedly installed on the two side surfaces of the bottom plate. Through grooves are provided on both side surfaces of the U-shaped plate. Vertical rods are fixedly installed between the upper and lower end inner walls of each of the two through grooves. Heat insulation connecting plates are fitted and movably sleeved on the surfaces of the two vertical rods. An electric heating plate is fixedly installed between the two heat insulation connecting plates.
[0011] As a preferred embodiment, a cylinder is fixedly installed on the top surface of the U-shaped plate. A heat insulation plate is fixedly installed on the outer wall surface of the electric heating plate. The output end of the cylinder movably penetrates through the top surface of the U-shaped plate and is fixedly connected to the top surface of the heat insulation plate.
[0012] As a preferred embodiment, two heat insulation scraping plates are fixedly installed on the inner wall surface at the top end of the U-shaped plate. One side surface of each of the two heat insulation scraping plates is in a fitting contact relationship with the two side surfaces of the electric heating plate.
[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:
[0014] 1. In this utility model, when it is necessary to stably dock two large-diameter PE pipes, first place the two PE pipe bodies inside each group of V-shaped lower clamping plates. Then rotate the two turntables. The rotation of the two turntables drives the rotation of the two second threaded rods. The rotation of the two second threaded rods drives the two sliding plates to slide on the surfaces of the multiple vertical rods. The movement of the two sliding plates drives the movement of the two cross plates. The movement of the two cross plates drives the movement of each group of V-shaped upper clamping plates. When each group of V-shaped lower clamping plates and each group of V-shaped upper clamping plates can firmly clamp the two PE pipe bodies, at this time, operate the two forward and reverse motors through the control terminal. The operation of the two forward and reverse motors drives the rotation of the two first threaded rods. The two movable plates and the multiple L-shaped plates are fixedly connected correspondingly. At the same time, slide with the aid of the two first threaded rods and the two T-shaped grooves, so that the two movable plates and each group of L-shaped plates move in opposite directions. The movement of each group of L-shaped plates in opposite directions drives the two connecting blocks to move in opposite directions, and further makes the multiple vertical rods move in opposite directions in groups of two. Since the two PE pipe bodies are fixed by the multiple V-shaped lower clamping plates and the multiple V-shaped upper clamping plates, the two PE pipe bodies move in opposite directions. When the two ends of the two PE pipe bodies are closely docked, stop operating the two forward and reverse motors at this time. Through the cooperation of the above structure, both ends of the two large-diameter PE pipe bodies are provided with two V-shaped upper clamping plates and two V-shaped lower clamping plates for clamping and fixing, and the stability is relatively high. When performing butt fusion welding, it is less likely to be unstable.
[0015] 2. In this utility model, when it is necessary to clean the plastic residues on the surface of the electric heating plate, first fix the two PE pipe bodies through the stable docking assembly. Then move the two PE pipe bodies so that the two ends of the two PE pipe bodies are closely attached to both sides of the electric heating plate. Then operate the electric heating plate through the control terminal. The operation of the electric heating plate heats and melts the two ends of the two PE pipe bodies. When heated to the appropriate degree, stop operating the electric heating plate and operate the cylinder. The operation of the cylinder drives the electric heating plate to move upward. The movement of the electric heating plate drives the two heat insulation connecting plates to move upward on the surfaces of the two vertical rods. The upward movement of the electric heating plate makes it insert between the two heat insulation scraping plates. The movement of the electric heating plate enables the two heat insulation scraping plates to scrape off the plastic residues on both sides of the electric heating plate. Then the scraped plastic can be removed with gloves. Finally, drive the two PE pipe bodies to dock through the two forward and reverse motors to achieve the purpose of butt fusion welding of the two PE pipe bodies. Through the cooperation of the above structure, the electric heating plate can move upward after heating the two PE pipe bodies to avoid affecting the welding. At the same time, the two heat insulation scraping plates can scrape off the unfrozen plastic on both sides of the electric heating plate to avoid affecting the subsequent butt fusion welding.

[0029] Specifically: Each group of V-shaped lower clamping plates 407 and each group of V-shaped upper clamping plates 412 play a role in clamping and fixing the two large-diameter PE pipe bodies 3.
[0030] In one embodiment, support plates 413 are fixedly installed on the top surfaces of multiple vertical rods 409 in groups of two.

The inner walls at the bottom ends on both sides of the U-shaped plate 501 are fixedly installed on the surfaces of both sides of the bottom plate 1. Through grooves 502 are formed on the surfaces of both sides of the U-shaped plate 501. Vertical rods 503 are fixedly installed between the inner walls at the upper and lower ends of the two through grooves 502.

[0035] Specifically: The cylinder 506 functions to drive the electric heating plate 505 to move.
[0036] In one embodiment, two heat insulation scraping plates 507 are fixedly installed on the inner wall surface at the top end of the U-shaped plate 501. One side surfaces of the two heat insulation scraping plates 507 are in a closely fitting position relationship with the two side surfaces of the electric heating plate 505.
[0037] Specifically: When the electric heating plate 505 is inserted between the two heat insulation scraping plates 507, one side surfaces of the two heat insulation scraping plates 507 are in close contact with the two side surfaces of the electric heating plate 505.
[0038] Working principle: When it is necessary to stably dock two large-diameter PE pipes, first place the two large-diameter PE pipe bodies 3 inside each group of V-shaped lower clamping plates 407. Then rotate the two turntables 415. The rotation of the two turntables 415 drives the rotation of the two second threaded rods 414. The rotation of the two second threaded rods 414 drives the two sliding plates 410 to slide on the surfaces of the multiple vertical rods 409. The movement of the two sliding plates 410 drives the movement of the two cross plates 411. The movement of the two cross plates 411 drives the movement of each group of V-shaped upper clamping plates 412. When each group of V-shaped lower clamping plates 407 and each group of V-shaped upper clamping plates 412 can firmly clamp the two large-diameter PE pipe bodies 3, at this time, operate the two forward and reverse motors 403 through the control terminal 2. The operation of the two forward and reverse motors 403 drives the rotation of the two first threaded rods 402. The two movable plates 404 and the multiple L-shaped plates 406 are fixedly connected correspondingly. At the same time, slide by means of the two first threaded rods 402 and the two T-shaped grooves 405, so that the two movable plates 404 and each group of L-shaped plates 406 move in opposite directions. The movement of each group of L-shaped plates 406 in opposite directions drives the two connecting blocks 408 to move in opposite directions, and further enables every two of the multiple vertical rods 503 to move in opposite directions. Since the two large-diameter PE pipe bodies 3 are fixed by the multiple V-shaped lower clamping plates 407 and the multiple V-shaped upper clamping plates 412, the two large-diameter PE pipe bodies 3 move in opposite directions. When the two ends of the two large-diameter PE pipe bodies 3 are tightly docked, stop operating the two forward and reverse motors 403 at this time. Through the cooperation of the above structure, both ends of the two large-diameter PE pipe bodies 3 are provided with two V-shaped upper clamping plates 412 and two V-shaped lower clamping plates 407 for clamping and fixing, and the stability is relatively high. When docking and performing hot melt welding, it is less likely to be unstable;When it is necessary to clean the plastic residues on the surface of the electric heating plate 505, first fix the two large-diameter PE pipe bodies 3 through the stable docking component 4. Then move the two large-diameter PE pipe bodies 3 so that the two ends of the two large-diameter PE pipe bodies 3 are closely attached to the two side surfaces of the electric heating plate 505. Subsequently, operate the electric heating plate 505 through the control terminal 2. The electric heating plate 505 operates to heat and melt the two ends of the two large-diameter PE pipe bodies 3. When heated to an appropriate degree, stop operating the electric heating plate 505 and operate the cylinder 506. The operation of the cylinder 506 drives the electric heating plate 505 to move upward. The upward movement of the electric heating plate 505 drives the two heat insulation connecting plates 504 to move upward on the surfaces of the two vertical rods 503. The upward movement of the electric heating plate 505 causes it to be inserted between the two heat insulation scraping plates 507. The movement of the electric heating plate 505 enables the two heat insulation scraping plates 507 to scrape off the plastic residues on the two side surfaces of the electric heating plate 505. Subsequently, the scraped plastic can be removed with gloves. Finally, drive the two large-diameter PE pipe bodies 3 to dock through the two forward and reverse motors 403, so as to achieve the purpose of hot melt welding of the two large-diameter PE pipe bodies 3. Through the cooperation of the above structures, the electric heating plate 505 can move upward after heating the two large-diameter PE pipe bodies 3 to avoid affecting the welding. At the same time, the two heat insulation scraping plates 507 can scrape off the unfrozen plastic on the two side surfaces of the electric heating plate 505 to avoid affecting the subsequent hot melt welding.
