Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe cutting, in particular to a cutting device for a plastic pipe production line. Background Technique

[0002] The plastic pipe non-chip cutting machine is a device for cutting plastic pipes. Its working principle is that the moving table on the machine frame can move along the pipe extrusion direction during the cutting process, and maintain the same feeding speed as the pipe, and perform cutting through hydraulic feeding. It has the advantages of no dust, no chips, smooth and flat cut surface without burrs, etc.

[0003] When the existing plastic pipe non-chip cutting machine is in use, there are two types of clamping structures on the cutting machine. One is that two upper and lower clamps or multiple clamps distributed circumferentially approach each other to clamp the pipe. However, when such clamps are unfolded, they do not contact the pipe, resulting in no support at the bottom of the pipe during the process of the pipe passing through the cutting machine, making the pipe prone to deformation, thus affecting the measurement accuracy. The other is that a support roller supports the incoming pipe, and then the upper clamp moves down to clamp the pipe. After the clamp of this structure moves up to release the clamping of the pipe, the support roller can support the pipe, effectively avoiding pipe deformation. However, when the clamp of this structure is in use, the height of the support roller needs to be adjusted according to the diameter of the pipe so that the central axis of the pipe remains unchanged. And two groups of support rollers are symmetrically arranged at both ends of the plastic pipe non-chip cutting machine, and it is easy for the two groups of support rollers to have different heights when adjusted separately. Based on this, a cutting device for a plastic pipe production line is provided. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1 to 3 Figures 1 to 3 In an embodiment of the present utility model, a cutting device for a plastic pipe production line includes a cutting machine main body 1 composed of a moving table 101, an electric sliding table 102, and a machine base 103.

[0037] The T-shaped guide rail 201 is fixed on both sides of the end face of the moving table 101, and the T-shaped guide rails 201 are symmetrically distributed with the inlet and outlet on the moving table 101 as the center;

[0038]

[0038] The lifting table 203 is slidably sleeved outside the two T-shaped guide rails 201. The symmetric height of the V-shaped fixing seat 204 is the same as the top of the lifting table 203. The inclined support roller 205 is rotatably installed inside the two V-shaped fixing seats 204 and protrudes above the V-shaped fixing seat 204. There are two groups of inclined support rollers 205, and the two groups of inclined support rollers 205 are distributed in a "V" shape. The two groups of inclined support rollers 205 are used to support pipes with different diameters;

[0039] The clamping unit includes an electric push rod 206 and a clamping block 207;

[0040] There are two electric push rods 206. The two electric push rods 206 are symmetrically fixed on both sides of the end face of the moving table 101 and are located above the V-shaped fixing seat 204. The two electric push rods 206 are distributed in a "V" shape and the output ends face down. The clamping block 207 is fixed to the output end of the electric push rod 206;

[0041] The electric push rod 206 operates to drive the clamping block 207 to move down to clamp the pipe;

[0042] The adjustment unit includes a fixed limit plate 202, a U-shaped lifting arm 208, a tooth groove 209, a fixing plate 210, a gear 211, a rotating shaft 212, and a handwheel 213;

[0043] The fixed limit plate 202 is fixed to the end face of the moving table 101 and is located below the fixed limit plate 202. There are two groups of fixed limit plates 202 and support units, which are symmetrically distributed at both ends of the moving table 101;

[0044] The two vertical parts of the U-shaped lifting arm 208 penetrate through the two fixed limit plates 202 and are fixedly connected to the bottoms of the two lifting platforms 203. The tooth grooves 209 are formed on the end faces of the two vertical parts of the U-shaped lifting arm 208 close to each other;

[0045] The fixing plate 210 is symmetrically fixed to the top of the fixed limit plate 202 with the U-shaped lifting arm 208 as the center line. The gears 211 are distributed in the middle of the two fixing plates 210 and are engaged with the tooth grooves 209;

[0046] The rotating shaft 212 is fixed to the middle of the gear 211 and is rotatably connected to the two fixing plates 210. One side of the rotating shaft 212 penetrates to the outside of the fixing plate 210 and is fixedly connected to the hand wheel 213;

[0047] By rotating the hand wheel 213, the U-shaped lifting arm 208 is lifted and lowered, so as to realize the synchronous lifting and lowering of the two lifting platforms 203.

[0048] In this embodiment: It should be added that: A circumferential driving assembly for driving the cutting knife to rotate circularly and a hydraulic pushing assembly for hydraulic feeding of the cutting knife are installed inside the moving table 101. After the plastic pipe passes through the moving table 101 and is clamped by the clamping assembly 2, the circumferential driving assembly drives the cutting knife to move circularly, and at the same time, the cutting knife is moved closer to the pipe by hydraulic feeding, so that the cutting operation of the pipe can be realized. Since this structure is an existing technology structure and this solution does not involve the improvement of this structural part, it is not described in detail herein;

[0049] During the process of the plastic pipe passing through the moving table 101, the bottom of the pipe contacts the surface of the inclined support roller 205. The rolling inclined support roller 205 can form a moving support for the pipe, so as to prevent the pipe from deforming due to support;

[0050] When the pipe needs to be cut, only need to start the electric push rod 206 to make the clamping block 207 press the upper surface of the pipe;

[0051] When cutting pipes with different diameters, it is necessary to adjust the height of the inclined support roller 205. At this time, only one handwheel 213 needs to be rotated. The handwheel 213 drives the gear 211 to rotate through the rotating shaft 212. The gear 211 can drive the U-shaped lifting arm 208 to move up and down through the tooth groove 209 engaged with it. Then, the inclined support rollers 205 on the two lifting platforms 203 move up and down synchronously. Through the lifting operation of the inclined support rollers 205, the pipes with different diameters being supported can be kept coaxial, thus ensuring the stable conveying of the pipes;

[0052] Through the above-mentioned multiple parts, the inclined support rollers 205 on the two lifting platforms 203 move up and down synchronously. Compared with the traditional step-by-step adjustment, not only is the operation efficiency faster, but also the situation where the heights of the inclined support rollers 205 are different can be effectively avoided.

[0053] Please refer specifically to Figures 1 to 3 , the adjusting unit further includes a through hole 214, a bolt hole 215, and a locking bolt 216;

[0054] The through hole 214 is opened on the side of the handwheel 213 and penetrates to the other side of the handwheel 213. There are multiple through holes 214 and they are evenly distributed in a ring shape;

[0055] The bolt hole 215 is opened on the side of a fixed plate 210 close to the handwheel 213 and is aligned with one through hole 214;

[0056] The locking bolt 216 penetrates through the through hole 214 and is threadedly connected to the bolt hole 215 for locking the rotation of the handwheel 213.

[0057] In this embodiment: When it is necessary to rotate the handwheel 213, it is necessary to first release the threaded connection between the locking bolt 216 and the bolt hole 215 on the two handwheels 213, and then the handwheel 213 can be rotated;

[0058] And after the adjustment is completed, another through hole 214 is aligned with the bolt hole 215. At this time, the locking bolt 216 is passed through this through hole 214 and threadedly connected to the bolt hole 215 to lock and fix the handwheel 213, so that the height of the inclined support roller 205 can be kept stable;

[0059] Through the structural settings of the two groups of handwheels 213 and the locking bolts 216, their locking state is more stable, and any one of the handwheels 213 can be rotated during the adjustment operation, and the operation is more flexible.

[0060] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
