Description

Technical Field

[0001] This utility model relates to the field of pipe production, and in particular to a traction machine for pipe production. Background Technology

[0002] Piping equipment is needed in construction, industry, agriculture and other fields. Piping refers to the pipe material used in pipeline systems to transport fluids, gases or solids. Different materials can be selected for different uses and requirements. During the production and processing of pipes, traction mechanisms are needed to pull and transport them.

[0003] A search of Chinese Patent Publication No. CN214002978U reveals a tracked traction machine for PVC pipe production. The machine includes a worktable with several first support rods on its top surface. Each first support rod has a first rotating roller mounted at its top, and the rollers are connected by a first conveyor belt. Vertical rods are installed at the four corners of the worktable's top surface, and their tops are fixedly connected by a horizontal plate. Several second support rods are located on the bottom surface of the horizontal plate, with second rotating rollers mounted at their bottom ends. These rollers are connected by a second conveyor belt. Two T-shaped grooves are formed on one side of the bottom surface of the horizontal plate and one side of the top surface of the worktable. Each T-shaped groove contains a T-shaped slider, which is fixed to the corresponding first or second support rod. In use, the pipe is placed between the first and second conveyor belts and pulled by them.

[0004] Since the width of the conveyor belt is usually larger than the size of the pipe, there is a larger area to move when placing the pipe. Therefore, the pipe may be placed off-center, affecting the traction effect. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5As shown, a traction machine for pipe production includes a cabinet 1. Four casters 101 are installed at the bottom corners of the cabinet 1. A fixed support assembly is provided on the side wall of the cabinet 1. The fixed support assembly includes mounting seats 102 fixedly connected to the four corners of the cabinet 1. A screw 103 is threaded into the mounting seat 102. A support seat 104 is rotatably connected to the bottom end of the screw 103. When the cabinet 1 does not need to move, the screw 103 is screwed down to reduce the contact between the casters 101 and the ground. The support seat 104 then supports the cabinet 1, improving its stability.

[0027] The top of the cabinet 1 is equipped with a traction mechanism, which includes two sets of conveyor belts 203 arranged vertically. One end of the conveyor belt 203 is a feed inlet. The traction mechanism also includes two mounting rods 201 fixedly connected to the top of the cabinet 1. Two frames 202 are slidably connected to the mounting rods 201. Each frame 202 is equipped with a conveyor belt 203 through a drive shaft and a driven shaft. The top of the mounting rods 201 is fixedly connected to a top plate 204. One-way screws 205 are rotatably connected to the top of the cabinet 1 and the bottom of the top plate 204. The two one-way screws 205 are not connected. The frames 202 are threadedly connected to the two different one-way screws 205. A first handwheel 206 is fixedly connected to the outer wall of the one-way screw 205.

[0028] The traction mechanism also includes a power assembly for driving two drive shafts to rotate. The power assembly includes a transmission shaft 301 rotatably connected to the top of the cabinet 1. Two drive boxes 302 are fixedly connected to the frame 202. A drive bevel gear 303 is rotatably connected to the inner top wall of the drive box 302. The drive bevel gear 303 and the transmission shaft 301 are slidably engaged by a spline. One end of the drive shaft extends into the drive box 302 and is fixedly connected to a driven bevel gear 304. The driven bevel gear 304 meshes with the drive bevel gear 303. The positions of the drive bevel gear 303 and the driven bevel gear 304 in the two drive boxes 302 are different. The lower end face of one driven bevel gear 304 meshes with the drive bevel gear 303, and the upper end face of the other driven bevel gear 304 meshes with the drive bevel gear 303, so that the two drive shafts rotate in opposite directions, thereby making the moving directions of the end faces of the conveyor belt 203 that are close to each other consistent. A power motor for driving the transmission shaft 301 to rotate is installed inside the cabinet 1.

[0029] A limiting mechanism is provided on the top of the cabinet 1. The limiting mechanism is located at one end of the feed inlet of the conveyor belt 203. The limiting mechanism includes two vertical plates 401 fixedly connected to the top of the cabinet 1. The two vertical plates 401 are arranged one in front of the other. A bidirectional screw 402 is rotatably connected between the two vertical plates 401. Two limiting plates 403 are threaded on the bidirectional screw 402. The front end of the bidirectional screw 402 extends out of the vertical plate 401 and is fixedly connected to a second handwheel 407. Several mounting grooves are opened on the side of the two limiting plates 403 that are close to each other. A rotating roller 404 is rotatably connected in the mounting groove. The rotating roller 404 reduces the friction between the pipe and the limiting plate 403.

[0030] A guide assembly is provided between the limiting plate 403 and the vertical plate 401. The guide assembly is used to guide the two limiting plates 403 to move towards or away from each other when the bidirectional lead screw 402 rotates. The guide assembly includes a guide rod 405, which is fixedly connected to the side of the two limiting plates 403 that is away from each other. The other end of the guide rod 405 passes through the vertical plate 401 and is fixedly connected to the limiting block 406. The guide rod 405 is slidably connected to the vertical plate 401.

[0031] Working principle: In use, the second handwheel 407 drives the bidirectional lead screw 402 to rotate, which in turn drives the two limit plates 403 to move closer to or further away from each other. This adjusts the size of the feed inlet according to the size of the pipe, preventing the pipe from being misaligned due to an excessively large movable area at the feed inlet, thus improving the traction effect. The first handwheel 206 drives the unidirectional lead screw 205 to rotate, which adjusts the height of the frame 202 and the spacing between the two sets of conveyor belts 203. The power motor inside the cabinet 1 drives the drive shaft 301 to rotate, which in turn drives the drive bevel gear 303 to rotate. The drive bevel gear 303 meshes with the driven bevel gear 304, which in turn drives the driven bevel gear 304 to rotate the drive shaft. The drive shaft then drives the two conveyor belts 203 to rotate, thus traction of the pipe.
