Description

Technical Field

[0001] This invention relates to the field of plastic pipe processing, specifically to a guide device with automatic clamping function for cutting and producing plastic pipes. Background Technology

[0002] Plastic pipe cutting equipment is used to cut plastic pipes. It can cut plastic pipes quantitatively according to their size. The guide device for plastic pipe cutting is used to guide the material when the pipe is cut and discharged. With the development of technology, the guide device for plastic pipe cutting production has been greatly developed. Its development has brought great convenience to people when guiding the material discharged from the cutting device, and its types and quantities are increasing day by day.

[0003] Currently, when cutting plastic pipes, users need to first fix the pipe to be cut with a clamp, then cut the pipe with a cutting machine, and then use a device to move the pipe in a specific direction. This process is repeated to cut the pipe, which is quite cumbersome. Summary of the Invention

[0007] V-shaped plates are fixedly connected to the sides of the two deflection sleeves. A locking rod is hinged to the side of the V-shaped plate. A first spring telescopic rod is hinged to the side of the locking rod, and the first spring telescopic rod is hinged to the side of the V-shaped plate.

[0008] A U-shaped slider is fixedly connected to the side of the power rod. The U-shaped slider slides inside the slide rail. A rotating rod is rotatably connected to the inner wall of the U-shaped slider. A limit rod is fixedly connected to the U-shaped slider, and the side of the limit rod abuts against the right side of the V-shaped plate.

[0009] Preferably, both sides of the U-shaped slider are fixedly connected to movable rods, the movable rods are fixedly connected with protrusions at equal intervals in a straight line, and the sides of the movable rods are fitted with limiting shells, which are fixed to the inner wall of the slide rail.

[0010] Preferably, the directional conveying mechanism includes a first one-way bearing, a fixed bearing is fixedly connected to the end face of the inner ring of the first one-way bearing, the outer side of the fixed bearing is fixed to the inner wall of the slide rail, a guide groove is provided on the outer side of the first one-way bearing, and a protrusion is slidably connected to the inner wall of the guide groove.

[0011] A second spring telescopic rod is fixedly connected to the inner wall of the first one-way bearing, and a second one-way bearing is fixedly connected to the end of the second spring telescopic rod away from the inner wall of the first one-way bearing.

[0012] Preferably, the cutting control mechanism includes a motor installed at the bottom of the slide rail, a worm gear fixedly connected to one end of the motor's rotating shaft, a worm wheel connected to the side of the worm gear, a rotating rod passing through the end face of the worm wheel, one end of the rotating rod being rotatably connected to the vertical plate, and a transmission belt sleeved on the side of the rotating rod and the side of the cylindrical rod.

[0013] A cam is fixedly sleeved on the side of the rotating rod, and a U-shaped lifting plate abuts against the side of the cam. The U-shaped lifting plate is slidably connected to the side of the slide rail. A third spring telescopic rod is fixedly connected to both ends of the U-shaped lifting plate, and the third spring telescopic rod is fixed to the side of the slide rail.

[0014] Preferably, the inner side of the U-shaped lifting plate abuts against a deflecting plate, the deflecting plate passes through a rectangular groove opened on the bottom surface of the slide rail and is fitted with a cutting machine, the deflecting plate is hinged to the inner wall of the slide rail, and a spring retraction rod is hinged between the deflecting plate and the slide rail.

[0015] Preferably, a support plate is movably sleeved on the side of the rotating rod, and the support plate is fixed on the support frame.

[0016] Preferably, the transmission component includes a grooved rod, which is fixed on a cylindrical rod. A cylinder is fixedly connected to the inner wall of the grooved rod. A sliding rod is hinged to the bottom end of the cylinder, and one end of the sliding rod is movably sleeved on the side of the power rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In this invention, the grooved rod on one end of the cylindrical rod is rotated by the transmission belt, which pulls the sliding rod to move to the left in the slide rail. When the sliding rod pulls the power rod to the left, the sliding rod deflects and cooperates with the torsion spring to drive the deflection sleeve to deflect and abut against the side of the limiting rod. At this time, the clamping rod cooperates with the rotating rod inside the U-shaped slider to clamp the plastic tube and pull it to the left. At this time, the outer ring of the second one-way bearing rolls on the tube, reducing the friction force of the tube moving to the left in the first one-way bearing.

[0019] In this invention, when the rotating rod drives the grooved rod to rotate half a revolution, the U-shaped slider moves to the left inside the slide rail. When the rotating rod drives the grooved rod to rotate the remaining half revolution, the U-shaped slider moves to the right inside the slide rail. At this time, since the outer ring of the second one-way bearing does not rotate, the plastic tube is prevented from moving to the right, thus completing the device's directional movement of the plastic tube to the left.

[0020] In this invention, the cylinder contracts to cause one end of the sliding rod to slide within the grooved rod, thereby changing the length of the grooved rod's power arm and reducing the distance the U-shaped slider moves left and right within the slide rail. This ensures that the device can adjust the length of the U-shaped slider's leftward guide plastic tube as needed, resulting in better practicality.

[0021] In this invention, when the U-shaped slider moves to the right inside the slide rail, the protrusion on the U-shaped slider moves to the right in the guide groove, causing the first one-way bearing to rotate clockwise. The second one-way bearing inside the first one-way bearing drives the plastic tube to rotate clockwise. At the same time, as the U-shaped slider moves to the right inside the slide rail, the rotating rod drives the cam to rotate, which pushes the U-shaped lifting plate upward, causing the deflection plate to deflect and drive the cutting machine on it to deflect and abut against the plastic tube, cutting the plastic tube. Since the plastic tube is rotating clockwise at this time, it works with the cutting machine to achieve the purpose of the device to perform circumferential cutting on the plastic tube. By repeating the above operation, the device can achieve equal-length guidance and cutting of the plastic tube, which is simple and convenient to operate. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 7 The present invention provides a technical solution: a guide device with automatic clamping function for cutting and producing plastic pipe fittings, including a support frame 1, a slide rail 2 fixedly connected to the top surface of the support frame 1, a pipe fitting conveying mechanism 3 slidably connected inside the slide rail 2, a directional conveying mechanism 4 slidably connected to the side of the pipe fitting conveying mechanism 3, and the directional conveying mechanism 4 installed on the bottom surface of the inner wall of the slide rail 2.

[0032] The bottom surface of slide rail 2 is equipped with a cutting and control mechanism 5.

[0033] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, the pipe conveying mechanism 3 includes a vertical plate 31 fixed on the support frame 1. A columnar rod 32 is provided on the vertical plate 31. A transmission component 33 is fixedly sleeved on the side of the columnar rod 32. A power rod 34 is rotatably connected to the end of the transmission component 33 away from the columnar rod 32. Two torsion springs 35 are movably sleeved on the side of the power rod 34. One end of the torsion spring 35 is fixedly connected to the side of the power rod 34. The other end of the torsion spring 35 is fixedly connected to a deflection sleeve 36, and the deflection sleeve 36 is rotatably connected to the side of the power rod 34.

[0034] Two deflection sleeves 36 are fixedly connected to the sides of a V-shaped plate 37. A locking rod 38 is hinged to the side of the V-shaped plate 37. A first spring telescopic rod 39 is hinged to the side of the locking rod 38. The first spring telescopic rod 39 is hinged to the side of the V-shaped plate 37.

[0035] A U-shaped slider 310 is fixedly connected to the side of the power rod 34. The U-shaped slider 310 slides inside the slide rail 2. A rotating rod 311 is rotatably connected to the inner wall of the U-shaped slider 310. A limit rod 312 is fixedly connected to the U-shaped slider 310, and the side of the limit rod 312 abuts against the right side of the V-shaped plate 37.

[0036] In this embodiment, as Figure 6 As shown, both sides of the U-shaped slider 310 are fixedly connected with moving rods 313. The moving rods 313 are fixedly connected with protrusions 314 at equal intervals in a straight line. The side of the moving rods 313 is fitted with a limiting shell 315, and the limiting shell 315 is fixed on the inner wall of the slide rail 2.

[0037] In this embodiment, as Figure 5 As shown, the directional conveying mechanism 4 includes a first one-way bearing 41, a fixed bearing 42 is fixedly connected to the end face of the inner ring of the first one-way bearing 41, the outer side of the fixed bearing 42 is fixed to the inner wall of the slide rail 2, a guide groove 43 is provided on the outer side of the first one-way bearing 41, and a protrusion 314 is slidably connected to the inner wall of the guide groove 43.

[0038] A second spring telescopic rod 44 is fixedly connected to the inner wall of the first one-way bearing 41, and a second one-way bearing 45 is fixedly connected to the end of the second spring telescopic rod 44 away from the inner wall of the first one-way bearing 41. One end of the second spring telescopic rod 44 is fixedly connected to the inner ring of the second one-way bearing 45, and an anti-slip washer is fixedly fitted on the outer ring of the second one-way bearing 45 to increase the friction between the outer ring of the second one-way bearing 45 and the outside of the plastic tube.

[0039] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the cutting control mechanism 5 includes a motor 51 installed at the bottom of the slide rail 2. One end of the rotating shaft of the motor 51 is fixedly connected to a worm gear 52. The side of the worm gear 52 is connected to a worm wheel 53. A rotating rod 54 passes through the end face of the worm wheel 53. One end of the rotating rod 54 is rotatably connected to the vertical plate 31. A transmission belt 513 is sleeved on the side of the rotating rod 54 and the side of the column rod 32.

[0040] A cam 55 is fixedly sleeved on the side of the rotating rod 54. The side of the cam 55 abuts against a U-shaped lifting plate 56, and the U-shaped lifting plate 56 is slidably connected to the side of the slide rail 2. Both ends of the U-shaped lifting plate 56 are fixedly connected to a third spring telescopic rod 57, and the third spring telescopic rod 57 is fixed to the side of the slide rail 2. The motor 51 drives the worm gear 52 to rotate, which in turn drives the worm wheel 53 to rotate the rotating rod 54 clockwise. This causes the transmission belt 513 to drive the grooved rod 331 on one end of the cylindrical rod 32 to rotate, pulling the sliding rod 333 to move to the left within the slide rail 2. When the sliding rod 333 pulls the power rod 34 to move to the left, the sliding rod 333 deflects and, in conjunction with the torsion spring 35, drives the deflection sleeve 36 to deflect and abut against the side of the limiting rod 312. At this time, the clamping rod 38 cooperates with the rotating rod 311 inside the U-shaped slider 310 to clamp the plastic tube and pull it to the left.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the inner side of the U-shaped lifting plate 56 abuts against the deflection plate 58. The deflection plate 58 passes through the rectangular groove 59 opened on the bottom surface of the slide rail 2 and is fitted with a cutting machine 510. The deflection plate 58 is hinged to the inner wall of the slide rail 2, and a spring retraction rod 511 is hinged between the deflection plate 58 and the slide rail 2. When the U-shaped slider 310 moves to the right inside the slide rail 2, the semi-circular protrusion on the side of the cam 55 pushes the U-shaped lifting plate 56 upward, causing the deflection plate 58 to deflect and drive the cutting machine 510 on it to deflect and abut against the plastic tube to cut the plastic tube. Conversely, when the U-shaped slider 310 moves to the left inside the slide rail 2, the deflection plate 58 deflects and drives the cutting machine 510 on it to deflect away from the plastic tube.

[0042] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, a support plate 512 is movably sleeved on the side of the rotating rod 54, and the support plate 512 is fixed on the support frame 1. The support plate 512 ensures the stability of the rotating rod 54 during rotation.

[0043] In this embodiment, as Figure 1As shown, the transmission component 33 includes a grooved rod 331, which is fixed to the cylindrical rod 32. A cylinder 332 is fixedly connected to the inner wall of the grooved rod 331. A sliding rod 333 is hinged to the bottom end of the cylinder 332, and one end of the sliding rod 333 is movably sleeved on the side of the power rod 34. The retraction of the cylinder 332 causes one end of the sliding rod 333 to slide within the grooved rod 331, thereby changing the length of the power arm of the grooved rod 331. This reduces the distance that the rotation of the grooved rod 331 causes the U-shaped slider 310 to move left and right within the slide rail 2, thus ensuring that the device can change the length of the leftward guide plastic tube of the U-shaped slider 310 as needed, improving its practicality.

[0044] The method of use and advantages of the present invention: The working process of the guide device with automatic clamping function for cutting and producing plastic pipe fittings is as follows:

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown: When using this device, the user inserts the plastic tube to be cut through the three first one-way bearings 41. The second one-way bearing 45, under the elastic force of the second spring telescopic rod 44, abuts against the outside of the plastic tube. At this time, the clamping rod 38 and the rotating rod 311 are both on the outside of the tube. Then, the cylinder 332 retracts, causing one end of the sliding rod 333 to slide within the grooved rod 331, thereby changing the length of the power arm of the grooved rod 331. This reduces the distance that the U-shaped slider 310 moves left and right within the slide rail 2, thus ensuring that the device can change the length of the plastic tube guided to the left by the U-shaped slider 310 as needed.

[0046] At this time, the motor 51 drives the worm 52 to rotate, which in turn causes the worm wheel 53 to rotate the rotating rod 54 clockwise. This causes the transmission belt 513 to drive the grooved rod 331 on one end of the cylindrical rod 32 to rotate, pulling the sliding rod 333 to move to the left in the slide rail 2. When the sliding rod 333 pulls the power rod 34 to move to the left, the sliding rod 333 deflects and cooperates with the torsion spring 35 to drive the deflection sleeve 36 to deflect and abut against the side of the limit rod 312. At this time, the clamping rod 38 cooperates with the rotating rod 311 inside the U-shaped slider 310 to clamp the plastic tube and pull it to the left. At this time, the outer ring of the second one-way bearing 45 rolls on the tube, reducing the friction of the tube moving to the left in the first one-way bearing 41. When the U-shaped slider 310 moves to the left, it drives the protrusion 314 to move to the left in the guide groove 43. At this time, the outer ring of the first one-way bearing 41 rotates, while the inner ring does not rotate.

[0047] Since the length between the grooved rod 331 and the sliding rod 333 is fixed, when the rotating rod 54 drives the grooved rod 331 to rotate half a turn, the grooved rod 331 and the sliding rod 333 cooperate to pull the U-shaped slider 310 to move to the left inside the slide rail 2. When the rotating rod 54 drives the grooved rod 331 to rotate the remaining half turn, the grooved rod 331 and the sliding rod 333 cooperate to push the U-shaped slider 310 to move to the right inside the slide rail 2. At this time, since the outer ring of the second one-way bearing 45 does not rotate, the plastic tube is prevented from moving to the right, thus completing the device's directional movement of the plastic tube to the left.

[0048] When the U-shaped slider 310 moves to the right inside the slide rail 2, the protrusion 314 on the U-shaped slider 310 moves to the right in the guide groove 43, causing the first one-way bearing 41 to rotate clockwise. The second one-way bearing 45 inside the first one-way bearing 41 drives the plastic tube to rotate clockwise. At the same time as the U-shaped slider 310 moves to the right inside the slide rail 2, the rotating rod 54 drives the cam 55 to rotate. The semi-circular protrusion on the side of the cam 55 pushes the U-shaped lifting plate 56 upward, causing the deflection plate 58 to deflect and drive the cutting machine 510 on it to deflect and abut against the plastic tube to cut the plastic tube. Since the plastic tube is rotating clockwise at this time, it works with the cutting machine 510 to achieve the purpose of the device to perform circumferential cutting on the plastic tube. By repeating the above operation, the device can achieve equal length guidance and cutting of the plastic tube.

[0049] When the U-shaped slider 310 is about to move to the left again inside the slide rail 2, the semi-circular protrusion on the side of the cam 55 separates from the bottom surface of the U-shaped lifting plate 56. The U-shaped lifting plate 56 moves down under the action of the third spring telescopic rod 57. At this time, the spring retraction rod 511 pulls the deflection plate 58 and the cutting machine 510 to deflect and reset.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
