However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0026] like Figure 1-Figure 5 As shown, a high-efficiency, energy-saving and multifunctional PVC pipe automatic production and cutting device comprises a left end plate 1, a horizontal U-shaped mounting frame 2 is arranged on the right end surface of the left end plate 1, a winding mechanism is arranged on the left end of the U-shaped mounting frame 2, a sliding mechanism is arranged on the U-shaped mounting frame 2, the winding mechanism is linked with the sliding mechanism, a cutting mechanism is arranged on the sliding mechanism, a group of sliding rods 3 are arranged on the right end surface of the U-shaped mounting frame 2, a driving mechanism is slidingly arranged on the sliding rods 3, the driving mechanism is linked with the sliding mechanism, a right end plate 4 is arranged on the right end of the group of sliding rods 3, and a support plate 5 is arranged on the right end of the bottom of the U-shaped mounting frame 2.

[0027] In the above technical scheme, the present invention sets a driving mechanism, a sliding mechanism and a winding mechanism. In the process of cutting the PVC pipe to a fixed length during production, the second cylinder 19 in the driving mechanism is first driven to take in air, and the abutment plate 20 is driven to cross downward to the right midline position of the feeding hole 21 on the movable plate 16. As the traction machine pulls the PVC pipe, the PVC pipe passes through the left end plate 1, the U-shaped mounting frame 2 and the feeding hole 21 opened on the movable plate 16 in turn and abuts against the abutment plate 20. In this process, the first motor 6 reverses first and loses the winding of the first connecting rope 8. The traction machine continues to pull, and the end of the PVC pipe abuts against the driving mechanism on the slide bar 3 to the right. The synchronous sliding mechanism moves synchronously to the right under the drive of a group of second connecting ropes 18, and then the second motor The machine 14 is started, and then the first cylinder 12 is started, which can realize the accompanying cutting of the PVC pipe in the pulling direction. There is no need for the PVC pipe production equipment to make intermittent movements to cooperate with the cutting of the PVC pipe, which speeds up the entire PVC pipe production process; after the cutting is completed, the first cylinder 12 and the second cylinder 19 are de-aired synchronously, and the cutting mechanism and the abutment plate 20 move upward, and then the first motor 6 rotates forward, driving the winch 7 to reel in the first connecting rope 8, driving the sliding mechanism, the cutting mechanism and the driving mechanism to move to the left, completing a work process; when the cut PVC pipe just falls from the feeding hole 21 on the moving plate 16, the first cutting action is synchronized, and it can be cut again, and the continuous cutting of the PVC pipe does not require shutdown, which is highly efficient and energy-saving.

[0028] In the present invention, the winding mechanism includes a first motor 6 installed at the left end of the U-shaped mounting frame 2, the output shaft of the first motor 6 passes through the top of the U-shaped mounting frame 2 and is rotatably connected thereto, the output shaft of the first motor 6 passes through the top part of the U-shaped mounting frame 2 on which a winch 7 is installed, and the winch 7 is wound with a first connecting rope 8.

[0029] In the above technical solution, by setting up a winding mechanism, the forward or reverse rotation of the first motor 6 can drive the winch 7 to rotate, and the first connecting rope 8 is wound up or released. When traveling, the first motor 6 is reversed, and the winch 7 releases the first connecting rope 8. After the cutting is completed, the first motor 6 rotates forward, driving the winch 7 to wind up the first connecting rope 8, thereby driving the sliding mechanism, the cutting mechanism and the driving mechanism to return to their positions, and prepare for the next cutting.

[0030] In the present invention, the sliding mechanism includes a slide groove 9 opened at the top of the U-shaped mounting frame 2, the slide groove 9 penetrates into the U-shaped mounting frame 2, a slide plate 10 is slidably connected in the slide groove 9, a follower plate 11 is fixedly connected to the top of the slide plate 10, the length of the follower plate 11 is greater than the length of the slide plate 10, and the two ends of the follower plate 11 extend over the edges of the two ends of the slide plate 10, the bottom of the follower plate 11 extends over the edge portions of the two ends of the slide plate 10 and slides with the top surface of the U-shaped mounting frame 2, and the first connecting rope 8 is connected to the center of the left end surface of the follower plate 11 away from the winch 7.

[0031] In the above technical solution, by setting a sliding mechanism, the slide plate 10 slides in the slide groove 9, providing a path for the movement of the entire cutting mechanism. By connecting the left end face of the follower plate 11 to the first connecting rope 8 and the right end face of the follower plate 11 to the second connecting rope 18, the winding mechanism, the sliding mechanism and the driving mechanism are linked, which provides a prerequisite for the entire cutting process of the PVC pipe.

[0032] In the present invention, the cutting mechanism includes a first cylinder 12, which is fixedly mounted on the common surface of the right ends of the follower plate 11 and the slide plate 10, and a U-shaped frame 13 is fixedly connected to the bottom of the output end of the first cylinder 12, and a second motor 14 is installed on the right end surface of the U-shaped frame 13, and the output shaft of the second motor 14 passes through the left end surface of the U-shaped frame 13, and a cutter 15 is installed on the output shaft of the second motor 14 located inside the U-shaped frame 13.

[0033] In the above technical solution, by setting up a cutting mechanism, when cutting, first the second motor 14 rotates to drive the cutter 15 to rotate, and then the first cylinder 12 takes in air, which can drive the U-shaped frame 13 and the second motor 14 installed thereon to move downward, and then drive the cutter to move downward to cut the PVC pipe.

[0034] In the present invention, the driving mechanism includes a moving plate 16, which is slidably connected to a group of sliding rods 3. A mounting block 17 is installed on the top of the moving plate 16. A group of second connecting cables 18 are connected to the left end surface of the mounting block 17. The left ends of a group of second connecting cables 18 are respectively fixedly connected to the two ends of the first cylinder 12 on the follower plate 11. A second cylinder 19 is arranged near the top position in the center of the right end surface of the moving plate 16. The output end of the second cylinder 19 faces downward and a contact plate 20 is arranged at its end.

[0035] In the above technical solution, by setting a driving mechanism, before cutting, the second cylinder 19 firstly inhales air to drive the abutment plate 20 to cross downward to the position of the material hole 21 on the movable plate 16 (there is a certain gap between the abutment plate 20 and the movable plate 16), so that the movement of the PVC pipe can drive the driving mechanism to move, and after the cutting is completed, the second cylinder 19 inhales air to drive the abutment plate 20 to lose the abutment with the PVC pipe. The cutting mechanism can return to its position for the next cutting.

[0036] In the present invention, the left end plate 1, the U-shaped mounting frame 2 and the movable plate 16 are all provided with coaxial material holes 21 to facilitate the passage of the PVC pipe.

[0037] In the present invention, the U-shaped mounting frame 2 and the left end surface of the movable plate 16 are provided with auxiliary wheel groups at both upper and lower positions of the material passing hole 21, and the structures of the auxiliary wheel groups are the same. The auxiliary wheel group at the lower end of the material passing hole 21 on the left end surface of the movable plate 16 includes an L-shaped fixing plate 22, and the L-shaped fixing plate 22 is fixedly connected to the position below the material passing hole 21 on the left end surface of the movable plate 16 by bolts 23. A U-shaped wheel frame 24 is provided on the top of the L-shaped fixing plate 22, and a concave auxiliary wheel 25 is rotatably connected inside the U-shaped wheel frame 24.

[0038] In the above technical solution, auxiliary wheel groups are arranged on the upper and lower sides of the feed hole 21 opened on the left end surface of the U-shaped mounting frame 2 and the movable plate 16. The cut PVC pipe can be kept horizontal under the limit of the two sets of auxiliary wheel groups, so that the end of the uncut PVC pipe can be against the end of the cut PVC pipe to push the cut PVC pipe to move.

[0039] It is worth noting that the start and stop of the first motor 6 and the second motor 14 and the intake and intake of the first cylinder 12 and the second cylinder 19 in the present invention are all controlled by a PLC controller, which is well known to those skilled in the art, and therefore, is not elaborated in detail in the present invention.
