The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figure 1 and Figure 2 A pipe cutting machine according to an embodiment of the present utility model is described.

[0024] like Figure 1 and Figure 2 As shown, the pipe cutting machine according to an embodiment of the present invention includes a conveyor line 100, a fixing device 200, a rotary cutting disc 300, and a pipe cutting device 400.

[0025] The conveyor line 100 supports the lower side of the pipe 700; the fixing device 200 fixes the pipe 700 to be cut; the rotary cutting disc 300 has a disc through hole 310 through which the pipe 700 can pass. The direction of the rotary cutting disc 300 closest to the disc through hole 310 is defined as the proximal end, and the direction of the rotary cutting disc 300 furthest from the disc through hole 310 is defined as the distal end. The direction of rotation toward the rotary cutting disc 300 is defined as the rotation side, and the direction of rotation opposite to the rotary cutting disc 300 is defined as the reverse side. The direction is the reverse rotation side; the tube cutting device 400 is connected to the rotary cutting turntable 300. The tube cutting device 400 includes a reciprocating control device 410, a slide 420, a blade bar 430 and a blade head 440. The reciprocating control device 410 can drive the slide 420 to reciprocate along the proximal and distal directions. The blade bar 430 is located on the slide 420. The blade head 440 is connected to the proximal end of the blade bar 430 through a connecting plate 450. The blade head 440 has a cutting edge 441 facing the rotation side.

[0026] For example, such as Figure 1 and Figure 2As shown, the conveyor line 100 supports the lower side of the pipe 700, so the conveyor line 100 itself does not need to move. The conveyor line 100 can be guided forward by either active or passive means. The fixing device 200 is used to fix the pipe 700 to be cut and is responsible for cutting the pipe 700 to a predetermined size. The rotary cutting disc 300 has a disc through hole 310, through which the pipe 700 can pass. That is, the rotation of the rotary cutting disc 300 does not affect the pipe 700's movement through the disc through hole 310. Considering the pipe cutting device 400 and the rotation of the rotary cutting disc 300, the direction of the rotary cutting disc 300 closest to the disc through hole 310 is defined as the near end, the direction of the rotary cutting disc 300 furthest from the disc through hole 310 is defined as the far end, the direction of rotation towards the rotary cutting disc 300 is defined as the rotating side, and the direction of rotation opposite to the rotary cutting disc 300 is defined as the reverse rotating side. The pipe cutting device 400 is connected to the rotary cutting disc 300, ensuring that the pipe cutting device 400 moves on the rotary cutting disc 300 following its rotation. The pipe cutting device 400 includes a reciprocating control device 410, a slide 420, a cutter bar 430, and a cutter head 440. The reciprocating control device 410 can drive the slide 420 to reciprocate along the proximal and distal directions. The cutter bar 430 is located on the slide 420. The cutter head 440 is connected to the proximal end of the cutter bar 430 through a connecting plate 450. The cutter head 440 has a cutting edge 441 facing the rotation side, enabling the cutter head 440 to complete the cutting of the pipe 700 through the cutting edge 441.

[0027] Taking the pipe cutting machine of this utility model located in front of the pipe injection molding machine as an example, the pipe 700 first passes through the turntable through hole 310 of the rotary cutting turntable 300 and moves along the conveyor line 100 until the pipe 700 reaches the predetermined position, that is, after meeting the predetermined cutting length, the pipe 700 is pressed and fixed by the fixing device 200 to prevent the pipe 700 from shifting.

[0028] Then the rotary cutting disc 300 rotates, causing the pipe cutting device 400 to rotate and move along the rotary cutting disc 300. Simultaneously, the reciprocating control device 410 drives the slide 420 to reciprocate along the proximal and distal directions, effectively driving the cutter head 440 to reciprocate and cut the pipe 700 sequentially. Figure 2 In one embodiment, the rotary cutting disc 300 and the pipe cutting device 400 rotate counterclockwise, while the pipe 700 is fixed in place by the fixing device 200. The blade 441, facing the rotating side of the cutter head 440, coordinates with the rotation direction of the rotary cutting disc 300. In this way, the cutter head 440 is equivalent to the pipe 700 reciprocating and performing repeated cutting actions. This cutting method ensures that the cutter head 440 can more easily complete the cutting of the pipe 700. It is sufficient to ensure that the above cutting process is stable enough without the fixing device 200 applying a lot of pressure to fix the pipe 700, avoiding the situation of blade jumping or chipping at the blade 441 position, thus ensuring both the cutting effect and protecting the cutter head 440.

[0029] In some embodiments of this utility model, reference is made to Figure 1 The pipe cutting machine of this utility model also includes a cutting box 500, which includes a front side plate 510 and a rear side plate 520. Both the front side plate 510 and the rear side plate 520 have through holes 530, through which the pipe 700 can pass and move forward. A conveyor line 100 is located in front of the cutting box 500, and a fixing device 200 is located in front of the front side plate 510. Inside the cutting box 500, a turntable drive device 320 and a rotary cutting turntable 300 are installed. The rotary cutting turntable 300 and the turntable drive device 320 are connected to the front of the rear side plate 520, and the turntable drive device 320 can drive the rotary cutting turntable 300 to rotate around a front-to-back extending axis.

[0030] The cutting box 500 is a relatively sealed box structure, including at least a front box panel 510 and a rear box panel 520. The front box panel 510 and the rear box panel 520 are structurally corresponding to each other, and both of these box panels are provided with through holes 530. The through holes 530 allow the pipe 700 to pass through smoothly and move forward, thereby realizing the pipe feeding process.

[0031] The conveyor line 100 is positioned in front of the cutting box 500 to facilitate the transport and positioning of the pipe. The fixing device 200 is installed on the front side of the front panel 510 of the cutting box 500 to fix the pipe and ensure the stability of the cutting process.

[0032] Inside the cutting box 500, there is at least one rotary drive device 320 and one rotary cutting disc 300. The rotary cutting disc 300 and the rotary drive device 320 are fixed to the front of the rear panel 520 via a specific connection method. The rotary drive device 320 has a driving function, which can effectively drive the rotary cutting disc 300 and the pipe cutting device 400 to rotate around a front-to-back extending axis, thereby achieving efficient cutting of the pipe 700. This design not only improves cutting accuracy but also greatly enhances cutting efficiency, making the entire cutting process smoother and more reliable.

[0033] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 The tool holder 430 has a tool mounting recess 431 at its proximal end. The tool mounting recess 431 has a first support wall 432 and a second support wall 433. The first support wall 432 is located at the distal end of the tool mounting recess 431, and the second support wall 433 is located on the counter-rotation side of the tool mounting recess 431. The tool head 440 has a first support surface 442 and a second support surface 443. The first support surface 442 abuts against the first support wall 432, and the second support surface 443 abuts against the second support wall 433.

[0034] The tool mounting recess 431 serves as a groove on the tool holder 430 for mounting the tool head 440. The tool mounting recess 431 has at least two support walls: a first support wall 432 and a second support wall 433. The first support wall 432 is located at the distal end of the tool mounting recess 431, corresponding to the first support surface 442 of the tool head 440. The second support wall 433 is located on the rotating side of the tool mounting recess 431, corresponding to the second support surface 443 of the tool head 440. When the tool head 440 is inserted and mounted on the tool holder 430, the first support surface 442 will press against and abut against the first support wall 432, and the second support surface 443 will press against and abut against the second support wall 433. This design effectively supports and fixes the tool holder 430 during tool mounting. Combined with the rotation direction of the rotary cutting disc 300, this not only ensures the stability of the tool head 440 on the tool holder 430 but also improves the service life and operational safety of the entire tool system.

[0035] In some embodiments of this utility model, the tool holder 430 has a tool holder screw hole 434, the cutter head 440 has a cutter head screw hole 444, and the connecting plate 450 has a connecting plate first screw hole 451 and a connecting plate second screw hole 452. The tool holder screw hole 434 and the connecting plate first screw hole 451 are connected by bolts, and the cutter head screw hole 444 and the connecting plate second screw hole 452 are connected by bolts. The tool holder 430 has a tool holder groove 435 on its front side, the cutter head 440 has a cutter head groove 445 on its front side, and the connecting plate 450 has a connecting plate first retaining strip 453 and a connecting plate second retaining strip 454 on its rear side. The connecting plate first retaining strip 453 locks the tool holder groove 435, and the connecting plate second retaining strip 454 locks the cutter head groove 445.

[0036] The tool holder 430 has a tool holder screw hole 434, the tool head 440 has a tool head screw hole 444, and the connecting plate 450 has a first connecting plate screw hole 451 and a second connecting plate screw hole 452, all of which are screw hole structures for accommodating bolts. In actual connection, the tool holder screw hole 434 and the first connecting plate screw hole 451 are tightly connected by high-strength bolts to ensure a stable connection between the tool holder and the connecting plate. Similarly, the tool head screw hole 444 and the second connecting plate screw hole 452 are also bolted together to ensure a secure fixation between the tool head and the connecting plate. Provided that the above connection process is met, the number and position of the tool holder screw hole 434, the tool head screw hole 444, the first connecting plate screw hole 451, and the second connecting plate screw hole 452 can be designed as needed.

[0037] Furthermore, the tool holder 430 has a tool holder groove 435 on its front side, and the tool head 440 also has a corresponding tool head groove 445 on its front side, so as to fit with the first retaining strip 453 and the second retaining strip 454 of the connecting plate 450. The first retaining strip 453 of the connecting plate precisely locks the tool holder groove 435, ensuring that the tool holder will not shift during the connection process; the second retaining strip 454 of the connecting plate firmly locks the tool head groove 445, further improving the connection reliability between the tool head and the connecting plate. Through this dual fixing method of bolt connection and groove retaining strip cooperation, the stability and durability of the entire structure are significantly improved.

[0038] In some embodiments of this utility model, an angle is formed between the first retaining strip 453 and the second retaining strip 454 of the connecting plate, that is, an angle is also formed between the cutter bar groove 435 and the cutter head groove 445. This angle design can improve the supporting force of the connecting plate 450 on the cutter head 440, making the cutter head 440 more stable.

[0039] In some embodiments of this utility model, the reciprocating control device 410 is located on the reverse rotation side of the slide 420. The reciprocating control device 410 includes a reciprocating drive motor 411 and a reciprocating drive turntable 412. A linkage block 421 is provided on the slide 420. A first connecting rod 413 and a second connecting rod 414 are sequentially connected between the reciprocating drive turntable 412 and the linkage block 421. The end of the first connecting rod 413 is connected to the reciprocating drive turntable 412 through a rotating shaft, and the second connecting rod 414 is connected to the linkage block 421 through a rotating shaft. The first connecting rod 413 and the second connecting rod 414 are connected by a rotating shaft, and the length of the first connecting rod 413 is more than four times the length of the second connecting rod 414. A guide rail 330 is provided on the rotary cutting turntable 300, and a slider 423 is provided on the slide 420. The slider 423 is slidably connected to the guide rail 330.

[0040] The reciprocating control device 410 is meticulously designed and installed on the counter-rotating side of the slide 420 to ensure precise execution of its function. This reciprocating control device 410 mainly consists of a reciprocating drive motor 411 and a reciprocating drive turntable 412, which work together to achieve reciprocating motion. A linkage block 421 is cleverly positioned above the slide 420 for transmitting and converting motion. The reciprocating drive turntable 412 and the linkage block 421 are linked by a series of sophisticated mechanical connections, specifically including a first link 413 and a second link 414. One end of the first link 413 is securely connected to the reciprocating drive turntable 412 via a shaft, while the other end is connected to the second link 414 via a shaft. The other end of the second link 414 is tightly connected to the linkage block 421 via a shaft, thus forming a complete motion transmission chain. Furthermore, a guide rail 330 is meticulously designed on the surface of the rotary cutting turntable 300 to ensure smooth movement of the slide 420. A slider 423 is specially provided on the slide block 420. The slider 423 is connected to the guide rail 330 by a sliding connection, which ensures that the slide block 420 moves smoothly and accurately on the rotary cutting turntable 300, thereby improving the working efficiency and accuracy of the entire device.

[0041] The linkage structure employs a combination of a first linkage 413 and a second linkage 414, requiring the length of the first linkage 413 to be at least four times the length of the second linkage 414. Essentially, the first linkage 413 acts as the main drive linkage for the reciprocating drive turntable 412, while the second linkage 414 acts as a driven buffer linkage. This allows for a buffer pause time when the slide 420 and cutter shank 430 retract from their extreme positions or advance from their extreme positions, utilizing the rotation time of the second linkage 414. This provides the cutter head 440 with more cutting time after entry, while the movable design of the second linkage 414 creates a buffering effect during cutting, protecting the cutter head 440.

[0042] In some embodiments of this utility model, the sliding groove 424 of the slide block 420 and the fine-tuning guide block 436 of the tool bar 430 are ensured to slide relative to each other. A fixing plate 422 is provided at the distal end of the slide block 420, and a screw 460 is inserted into the fixing plate 422. The screw 460 is rotatably connected to the fixing plate 422, and the proximal end of the screw 460 is threadedly connected to the distal end of the tool bar 430. A handwheel 461 is provided at the distal end of the screw 460.

[0043] The sliding groove 424 of the slide block 420 and the fine-tuning guide block 436 of the tool holder 430 ensure relative sliding movement, guaranteeing the stability and accuracy of the slide block 420 during sliding. This sufficiently precise sliding connection between the slide block 420 and the tool holder 430 enables smooth movement and precise fine-tuning of the tool holder on the slide block. The screw 460 rotates with the handwheel 461, allowing for precise adjustment of the tool holder 430's position. For manual adjustment of the screw 460, the operator simply rotates the handwheel 461. The handwheel 461 is comfortable to hold and easy to operate, allowing for easy fine-tuning of the tool holder's position, thereby improving the overall efficiency and accuracy of the device.

[0044] In some embodiments of this utility model, a scale 437 is provided on the side wall of the cutter bar 430, and an indicator 425 is provided on the slide block 420. The indicator 425 is located next to the scale 437. That is, when the cutter bar 430 is finely adjusted, the scale 437 also moves accordingly. By comparing with the indicator 425 on the slide block 420, the movement size of the cutter bar 430 can be accurately determined, which is equivalent to precisely controlling the position of the cutter head 440 to match the pipe size.

[0045] In some embodiments of this utility model, reference is made to Figure 1 , Figure 5 The fixing device 200 includes an upper clamping device 210 and a lower support base 220, which can support the lower side of the pipe 700. The clamping device 210 includes a clamping cylinder 211 and a clamping block 212. The clamping cylinder 211 can drive the clamping block 212 to move up and down. A pressure frame 213 is provided on the lower side of the clamping block 212, and a soft pressure pad 214 is provided on the lower side of the pressure frame 213.

[0046] The fixing device 200 works in conjunction with a movable upper clamping device 210 and a relatively fixed lower support frame 220. The main function of the support frame 220 is to firmly support the pipe 700 below it, ensuring the stability of the entire device during operation. The clamping cylinder 211 of the clamping device 210, through its power output, effectively drives the clamping block 212 to extend and retract. The clamping block 212 applies pressure to the pipe through the pressure frame 213, and the soft pressure pad 214 of the pressure frame 213 effectively reduces damage to the pipe surface, ensuring the integrity of the pipe is protected during clamping. Through these carefully designed components, the entire fixing device 200 achieves efficient fixing and clamping of the pipe 700, ensuring smooth operation.

[0047] In some embodiments of this utility model, the clamping cylinder 211 is connected to the front side of the front box plate 510, and the front box plate 510 has a through-hole 530. The rear end of the clamping frame 213 extends into the through-hole 530 of the front box plate 510. This effectively shortens the front-to-back distance between the clamping frame 213 and the pipe cutting device 400. This ensures that when the clamping frame 213 presses down on the pipe 700, the stability of the pipe cutting process of the pipe cutting device 400 is improved.

[0048] In some embodiments of this utility model, a height adjustment base 600 is provided on the lower side of the conveyor line 100. The height adjustment base 600 includes, from top to bottom, a lifting connecting seat 610, a lifting stud 620, and a support base 630. The lifting connecting seat 610 can move up and down along the thread of the lifting stud 620. The lower end of the lifting stud 620 is fixedly connected to the upper side of the support base 630. The upper side of the lifting connecting seat 610 is connected to the lower side of the conveyor line 100 through a connecting base frame 640. The lower side of the connecting base frame 640 is rotatably connected to the lifting connecting seat 610. In this way, by simply rotating the lifting connecting seat 610, the lifting connecting seat 610 can move up and down along the thread of the lifting stud 620, thereby driving the connecting base frame 640 and the conveyor line 100 on the connecting base frame 640 to move up and down to match the size of the pipe.

[0049] In some embodiments of this utility model, an adjustable base 600 is also provided on the lower side of the support base 220 to facilitate the height adjustment of the support base 220.

[0050] Other components and operations of the pipe production line according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0051] The following is for reference. Figure 1 and Figure 2 A pipe cutting machine according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0052] like Figure 1 and Figure 2 As shown, the pipe cutting machine of this utility model embodiment includes a conveyor line 100, a fixing device 200, a rotary cutting turntable 300, a pipe cutting device 400, a cutting box 500, and a height adjustment base 600, which is responsible for cutting the pipe 700.

[0053] The cutting box 500 includes a front side panel 510, a rear side panel 520, and a through-hole 530.

[0054] The fixing device 200 includes a clamping device 210, a clamping cylinder 211, a clamping block 212, a clamping frame 213, a soft pressure pad 214, and a supporting base frame 220.

[0055] The rotary cutting turntable 300 includes a turntable through hole 310, a turntable drive device 320, and a guide rail 330.

[0056] The pipe cutting device 400 includes a reciprocating control device 410, a reciprocating drive motor 411, a reciprocating drive turntable 412, a first connecting rod 413, a second connecting rod 414, a slide block 420, a linkage block 421, a fixing plate 422, a slider 423, a slide groove 424, an indicator 425, a cutter bar 430, a cutter mounting recess 431, a first support wall 432, a second support wall 433, a cutter bar screw hole 434, a cutter bar slot 435, a fine-tuning guide block 436, a scale 437, a cutter head 440, a cutting edge 441, a first support surface 442, a second support surface 443, a cutter head screw hole 444, a cutter head slot 445, a connecting plate 450, a connecting plate first screw hole 451, a connecting plate second screw hole 452, a connecting plate first retaining strip 453, a connecting plate second retaining strip 454, a screw 460, and a handwheel 461.

[0057] The height adjustment base 600 includes a lifting connecting seat 610, a lifting stud 620, a support base 630, and a connecting base frame 640.

[0058] According to the pipe cutting machine of this utility model embodiment, by the following configuration, at least the following effects can be achieved: the pipe 700 first passes through the turntable through hole 310 of the rotary cutting turntable 300 and advances along the conveyor line 100 until the pipe 700 reaches the predetermined position, that is, after meeting the predetermined cutting length, the pipe 700 is pressed and fixed by the fixing device 200 to prevent the pipe 700 from shifting, and the pipe cutting device 400 completes the cutting work in conjunction with the rotary cutting turntable 300; the rotary cutting turntable 300 rotates, driving the pipe cutting device 400 to follow on the rotary cutting turntable 300. The rotating movement, along with the reciprocating control device 410 driving the slide 420 to reciprocate along the proximal and distal directions, is equivalent to driving the cutter head 440 to reciprocate and cut the pipe 700 sequentially. This cutting method ensures that the cutter head 440 can more easily complete the cutting of the pipe 700. The fixing device 200 does not need to apply a lot of pressure to fix the pipe 700, which is enough to ensure that the above cutting process is stable enough and avoid the situation of blade jumping or chipping at the blade 441 position. This ensures both the cutting effect and the protection of the cutter head 440.
