Description

[0002] The main component of PVC is polyvinyl chloride, a material with other components added to enhance its heat resistance, toughness, and ductility. PVC pipes are rigid polyvinyl chloride pipes, which are extruded by hot pressing after being compounded with polyvinyl chloride resin, stabilizers, lubricants, etc. They are the earliest plastic pipes to be developed and applied. PVC pipes have strong corrosion resistance, are easy to bond, have a low price, and are hard in texture.

[0003] During the use of PVC pipes, it is necessary to cut and adjust the length of the PVC pipes to meet different usage requirements. During the cutting process of PVC pipes, a handsaw or an electric pipe cutter is often used to cut the pipes. During the cutting process, the common method is for the staff to place one PVC pipe after another at the designated position. After adjusting the cutting position, the cutting is carried out. Each PVC pipe requires manual operation by the staff. And after cutting, to improve the sealing performance and connection quality of the interface, it is also necessary to process the cut of the pipe, using a file, sandpaper, or a special pipe orifice trimming tool to trim the cut, remove burrs and uneven parts, and make the cut smooth and flat. A series of operations will consume a lot of time, the working speed is slow, and the working intensity is high. For this reason, a PVC pipe cutting device is proposed. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a PVC pipe cutting device.

[0038] In a typical implementation manner of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, a PVC pipe cutting device includes:

[0039] Pipe placing rotating cylinder 1, a bottom plate 2 is arranged below the pipe placing rotating cylinder 1, a side plate 3 is arranged on the bottom plate 2, a driving motor 4 is fixedly installed on one side of the side plate 3, an output end of the driving motor 4 is connected with a rotating shaft 5, the pipe placing rotating cylinder 1 is fixedly sleeved on the rotating shaft 5, placing station notches 6, cutting station notches 7, grinding station notches 8, and taking-out station notches 9 are formed in the pipe placing rotating cylinder 1. A pipe body 16 to be cut is placed on an inclined placing plate 14. Placing station notches 6, grinding station notches 8, taking-out station notches 9, and cutting station notches 7 are arranged on the pipe placing rotating cylinder 1. The above-mentioned station notches are named according to the up, down, left, and right of the pipe placing rotating cylinder 1. The placing station notch 6 located above is the placing station notch 6. They are named in sequence. The placing station notch 6 located above always places the pipe body 16. The cutting station notch 7 on one side always performs cutting operations on the pipe body 16. The station notches at each position are responsible for corresponding work.

[0040] Indirect feeding mechanism 13, the indirect feeding mechanism 13 is arranged at the upper position of the pipe placing rotating cylinder 1. The indirect feeding mechanism 13 includes an inclined placing plate 14 installed above the pipe placing rotating cylinder 1. A number of pipe bodies 16 are placed on the inclined placing plate 14. Indirect feeding of the pipe bodies 16 is realized through the indirect feeding mechanism 13. A connecting shaft 17 is rotatably installed on one side of the side plate 3. Four rotating adjusting plates 18 are fixedly installed on the connecting shaft 17. The rotating adjusting plates 18 are located above the pipe bodies 16. Synchronous rotation is achieved between the connecting shaft 17 and the rotating shaft 5 through transmission. A rotating shaft 19 is rotatably installed on one side of the side plate 3. A first transmission belt 20 is arranged between the rotating shaft 19 and the rotating shaft 5. A second transmission belt 21 is arranged between the rotating shaft 19 and the connecting shaft 17. An opposing inclined baffle 15 is fixedly installed on one side of the side plate 3. The opposing inclined baffle 15 is located at one side position of the rotating adjusting plate 18.

[0041] When performing cutting operations, start the driving motor 4 to run, drive the rotating shaft 5 to rotate slowly, thereby driving the pipe placing rotating cylinder 1 to rotate slowly. During the rotation process, the arranged indirect feeding mechanism 13 can drive the connecting shaft 17 to rotate under the transmission of the first transmission belt 20 and the second transmission belt 21. After the connecting shaft 17 rotates, it drives the rotating adjusting plates 18 to rotate. There are four rotating adjusting plates 18. Through the rotation of the rotating adjusting plates 18, the movement of the pipe bodies 16 on the inclined placing plate 14 can be indirectly controlled. When the pipe placing rotating cylinder 1 rotates one circle, the connecting shaft 17 also rotates one circle. Through the synchronous rotation setting, every time a pipe body 16 drops, it will enter an upper placing station notch 6. The arranged opposing inclined baffle 15 prevents the dropped pipe body 16 from slipping from the other side. The opposing inclined baffle 15 blocks the dropped pipe body 16 and waits for the placing station notch 6 to rotate to the upper side and then enter.

[0042] As a preferred implementation manner in this embodiment, as Figure 2 , Figure 4 , Figure 10 and Figure 11 shown, the position adjusting mechanism 43 is arranged on the pipe placing turntable 1 and is used to adjust the cutting length of the pipe body 16. The position adjusting mechanism 43 includes four adjusting slots 44 opened on the side of the pipe placing turntable 1. An adjusting rod 45 is movably installed on the adjusting slot 44. An end block 46 is fixedly installed at the end of the adjusting rod 45. A fixed block 47 is fixedly installed on one side of the pipe placing turntable 1. A plugging and blocking column 48 is movably installed on the fixed block 47. A connecting disk 49 is fixedly installed at one end of the plugging and blocking column 48. A return spring 50 is fixedly installed between the connecting disk 49 and the fixed block 47. A plurality of blocking slots 51 are opened on one side of the adjusting rod 45. The plugging and blocking column 48 is plugged into one of the blocking slots 51. A position scale 52 is arranged on the adjusting rod 45. An adjusting cylinder 53 is fixedly installed on one side of the side plate 3. The adjusting cylinder 53 is located at one side position of the placing station notch 6.

[0043] After the pipe body 16 enters the placing station notch 6, the adjusting cylinder 53 operates, which can push the placed pipe body 16 to move. The tail end of the pipe body 16 will contact the end block 46, so that the pipe body 16 can be accurately placed, and the fixed-length cutting operation can be realized. Compression notches 10 are opened on the side walls of the placing station notch 6, the cutting station notch 7, the grinding station notch 8, and the taking-out station notch 9. A telescopic cylinder 11 is fixedly installed on the inner wall of the compression notch 10. The output end of the telescopic cylinder 11 is connected with an arc-shaped compression plate 12. Starting the telescopic cylinder 11 to operate drives the arc-shaped compression plate 12 to move. The two arc-shaped compression plates 12 will clamp the placed pipe body 16, which is convenient for subsequent cutting and grinding operations.

[0044] Further, in the above solution, when it is necessary to adjust the cutting length of the pipe body 16, pull the connecting disk 49 to drive the plugging and blocking column 48 to move, and pull the return spring 50. After one end of the plugging and blocking column 48 disengages from the blocking slot 51, move the length position of the adjusting rod 45, so as to adjust the position of the end block 46, and the placement of the pipe body 16 can be adjusted to meet the cutting requirements of different lengths. A position scale 52 is arranged on the adjusting rod 45, which can accurately measure the cutting length, and the cutting position is more accurate.

[0045] As a preferred implementation manner in this embodiment, as Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the cutting mechanism 22 is arranged on one side of the cutting station notch 7 for cutting the pipe body 16; the grinding mechanism 26 is arranged on one side of the grinding station notch 8 for grinding the cut of the pipe body 16. An angular linkage adjustment mechanism 36 is connected between the cutting mechanism 22 and the grinding mechanism 26 for synchronously adjusting the angular positions of cutting and grinding. The cutting mechanism 22 includes a U-shaped frame 23 arranged on one side of the cutting station notch 7. A cutting motor 24 is fixedly installed on one side of the U-shaped frame 23. The output end of the cutting motor 24 is connected to a cutting cutter head 25. The cutting cutter head 25 is located inside the U-shaped frame 23. The grinding mechanism 26 includes a grinding motor 27 arranged on one side of the grinding station notch 8. The output end of the grinding motor 27 is connected to a placement disc 28. A compression groove 29 is formed on one side of the placement disc 28. A connecting block 30 is movably installed in the compression groove 29. A grinding disc 34 is fixedly installed on one side of the connecting block 30. An edge arc groove 35 is arranged on the grinding disc 34. A conveyor belt 42 is arranged on the base plate 2. The conveyor belt 42 is arranged at a position on one side of the extraction station notch 9.

[0046] With continuous rotation, the clamped pipe body 16 will rotate into the area of the cutting station notch 7. At this time, start the cutting motor 24 on the cutting mechanism 22 to run, drive the cutting cutter head 25 to rotate, and perform cutting operations on the rotated pipe body 16. The cutting of the pipe body 16 can be achieved through rotation. When the cut pipe body 16 continues to rotate and enters the grinding station notch 8, the grinding motor 27 runs to drive the placement disc 28 to rotate, thereby driving the grinding disc 34 to rotate to deburr and grind the cut port. When the grinding is completed, the pipe body 16 rotates to the position of the extraction station notch 9. At this time, the telescopic cylinder 11 runs to drive the arc-shaped pressing plate 12 to return to its original position, and the pipe body 16 is in a loose state. The staff can pull out the pipe body 16. The pulled-out pipe body 16 will be located on the conveyor belt 42 to realize the transportation of the cut pipe body 16. The overall cutting and grinding are integrated operations, eliminating the need for the staff to cut and grind each pipe body 16 one by one. The speed is fast and the work intensity is reduced.

[0047] Furthermore, in the above solution, a compression spring 31 is fixedly installed between the connecting block 30 and the inner wall of the compression groove 29. A limiting groove 32 is formed on the inner wall of the compression groove 29. A limiting block 33 is fixedly installed on the side of the connecting block 30. The limiting block 33 is slidably installed in the limiting groove 32. An edge arc groove 35 is provided on the grinding disc 34, which can facilitate the cutting port of the pipe body 16 to enter the grinding disc 34 and form a certain extrusion force with the grinding disc 34. Through extrusion, the connecting block 30 can be driven to move in the compression groove 29 and compress the compression spring 31. The provided limiting groove 32 and limiting block 33 limit the position and movement of the connecting block 30, and it can only move a tiny amplitude. Through the pushing force provided by the compression spring 31, it is ensured that the grinding disc 34 is always in contact with the cutting port of the pipe body 16, ensuring the grinding effect of the cutting port and avoiding the problems of poor contact between the grinding disc 34 and the cutting port and unsatisfactory deburring and grinding effect.

[0048] As a preferred implementation manner in this embodiment, as Figure 2 and Figure 9 shown, the angle linkage adjustment mechanism 36 includes a stepper motor 37 fixedly installed on the bottom plate 2. The bottoms of the U-shaped frame 23 and the grinding motor 27 are respectively fixedly installed with a first support rotating shaft 38 and a second support rotating shaft 39. The first support rotating shaft 38 and the second support rotating shaft 39 are both rotatably installed on the bottom plate 2. Sprockets 40 are provided on the output end of the stepper motor 37, the first support rotating shaft 38 and the second support rotating shaft 39. The three sprockets 40 are arranged in a triangular position, and the same drive chain 41 is sleeved on the three sprockets 40.

[0049] When it is necessary to make incisions in different directions for the pipe body 16, it is necessary to adjust the cutting direction of the cutting tool disc 25 and at the same time synchronously adjust the grinding direction of the grinding disc 34. Start the stepper motor 37 on the angle linkage adjustment mechanism 36 to run. The stepper motor 37 drives the sprocket 40 to rotate, thereby driving the drive chain 41 to rotate. The first support rotating shaft 38 and the second support rotating shaft 39 rotate synchronously, and the rotation angles and directions are the same. Therefore, the rotation angles of the cutting tool disc 25 and the grinding disc 34 will also be the same. After cutting, the cutting port can continue to be deburred and ground, and the grinding is not affected.

[0050] Working principle of the present invention: During use, place the pipe body 16 to be cut on the inclined placement plate 14. When performing the cutting operation, start the driving motor 4 to run, driving the pipe placement rotating cylinder 1 to rotate slowly. During the rotation process, the set indirect feeding mechanism 13, under the driving action of the first transmission belt 20 and the second transmission belt 21, can drive the connecting shaft 17 to rotate. After the rotating adjustment plate 18 rotates, it can indirectly control the movement of the pipe body 16. When the pipe placement rotating cylinder 1 rotates one circle, the connecting shaft 17 also rotates one circle. Through the synchronous rotation setting, every time a pipe body 16 drops, it will enter the upper placement station notch 6. When the pipe body 16 enters the placement station notch 6, start the adjusting cylinder 53 to run, which can accurately place the pipe body 16 and realize the fixed-length cutting operation. Start the telescopic cylinder 11 to run, driving the arc pressing plate 12 to move, and the two arc pressing plates 12 will clamp the placed pipe body 16, facilitating subsequent cutting and grinding operations;

[0051] With continuous rotation, the clamped pipe body 16 will rotate into the area of the cutting station notch 7. At this time, start the cutting motor 24 to run, driving the cutting tool disc 25 to rotate, and perform the cutting operation on the rotated pipe body 16. When the cut pipe body 16 continues to rotate and enters the grinding station notch 8, start the grinding motor 27 to run, driving the grinding disc 34 to rotate, and deburr and grind the cut port. After grinding, the pipe body 16 rotates to the position of the removal station notch 9, and the pipe body 16 is in a loose state. The staff can pull out the pipe body 16. The overall cutting and grinding operation of the pipe body 16 does not require the staff to cut and grind each pipe body 16 one by one, which is fast and reduces the work intensity;

[0052] When it is necessary to make cuts at different orientations of the pipe body 16, it is necessary to adjust the cutting orientation of the cutting tool disc 25, and at the same time, synchronously adjust the grinding orientation of the grinding disc 34. Start the stepping motor 37 on the angle linkage adjustment mechanism 36 to run. The stepping motor 37 runs to drive the sprocket 40 to rotate, thereby driving the transmission chain 41 to rotate. The first support rotating shaft 38 and the second support rotating shaft 39 rotate synchronously, and the rotation angles and orientations are the same. Therefore, the rotation angles of the cutting tool disc 25 and the grinding disc 34 will also be the same, and the cut port can continue to be deburred and ground after cutting, and the grinding is not affected.

[0053] It should be noted that:

[0054] What is proposed in this application: The driving motor 4, the telescopic cylinder 11, the cutting motor 24, the grinding motor 27, the stepping motor 37, and the conveyor belt 42 are all prior arts, and their specific structures, functions, and usage methods will not be elaborated in this text.

[0055] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
