[0028] It should be noted that the engineering plastic pipe cutter described in the utility model is used for but not limited to plastic pipes, etc. For the convenience of explanation, in the utility model, only an engineering plastic pipe cutter applied to plastic pipes is used as an example for explanation. The principle of applying an engineering plastic pipe cutter to other types of equipment is essentially the same as the principle applied to plastic pipes, which will not be repeated here.
[0029] See also Figure 1 - Figure 3 ,in Figure 1 This is a structural schematic diagram of an engineering plastic pipe cutter in an embodiment of the utility model, an engineering plastic pipe cutter includes a mounting plate 1, a moving rod 2, a transmission rod 3 and a cutting device 4, the mounting plate 1 is fixedly connected with a first guide block 11, the moving rod 2 is slidably connected to the mounting plate 1, and a plurality of through holes 21 are evenly spaced along the length direction of the moving rod 2, one end of the transmission rod 3 corresponds to the first guide block 11, the other end of the transmission rod 3 is connected to any one of the through holes 21 and maintains a different distance from the first guide block 11, the cutting device 4 is fixedly connected to the moving rod 2, and when the moving rod 2 slides, it drives the cutting device 4 to cut the plastic pipe.
[0030] In this embodiment, one end of the transmission rod 3 corresponds to the first guide block 11, so that the plastic tube touches the transmission rod 3 when it moves toward the transmission rod 3 along the first guide block 11, and then one end of the transmission rod 3 is connected to any through hole 21, so that when the plastic tube continues to move, it will drive the transmission rod 3 and the moving rod 2 to move together, thereby driving the cutting device 4 to automatically cut the plastic tube, wherein the staff can adjust the distance between the transmission rod 3 and the first guide block 11 by connecting the transmission rod 3 with different through holes 21, so that the cutting device 4 can cut plastic tubes of different lengths, thereby effectively improving the practicality of the utility model.
[0031] First, according to the required cutting length of the plastic tube, the transmission rod 3 selects a through hole 21 of a suitable distance for connection; then, the plastic tube passes through the first guide block 11 and moves toward the transmission rod 3 until the end of the plastic tube touches the transmission rod 3; finally, the plastic tube continues to move, and the transmission rod 3 is moved by the abutment of the plastic tube, and the transmission rod 3 drives the moving rod 2 to move together, thereby starting the cutting device 4 to cut the plastic tube.
[0032] In one embodiment, see Figure 1 The mounting plate 1 is provided with a first slideway 12 , in which a first slider 121 is slidably embedded, and the middle portion of the transmission rod 3 is hinged to the first slider 121 .
[0033] In this embodiment, the first slider 121 is moved along the length direction of the first slide 12 to change the distance between the transmission rod 3 and the first guide block 11, so that the processing of plastic tubes of different lengths can be achieved. The middle end of the transmission rod 3 is hinged to the first slider 121, so that when the plastic tube abuts against one end of the transmission rod 3 in one direction, the other end of the transmission rod 3 will move in the opposite direction, thereby realizing the movement of the moving rod 2 in the preset direction.
[0034] In one embodiment, see Figure 3 The first sliding block 121 is provided with a threaded hole 1211 , and a screw rod 122 is threadedly sleeved in the threaded hole 1211 .
[0035] In this embodiment, the two ends of the screw 122 are rotatably connected to the mounting plate 1 respectively. By rotating the screw 122, the first slider 121 can be moved along the length direction of the first slideway 12, thereby adjusting the distance between the transmission rod 3 and the first guide block 11, so that the cutting device 4 can cut the plastic pipe of the required length.
[0036] In one embodiment, see Figure 1 One end of the screw rod 122 is fixedly connected to a hand wheel 1221 .
[0037] In this embodiment, one end of the screw rod 122 penetrates the mounting plate 1 and is fixedly connected to the hand wheel 1221 . The function of the hand wheel 1221 is to facilitate the staff to rotate the screw rod 122 by rotating the hand wheel 1221 .
[0038] In one embodiment, see Figure 3 A second slideway 31 is provided at one end of the transmission rod 3 connected to the through hole 21 , a second slider 32 is slidably embedded in the second slideway 31 , and an end of the second slider 32 away from the second slideway 31 is hinged to the through hole 21 .
[0039] In this embodiment, since the middle end of the transmission rod 3 is hinged to the first slider 121, the two ends of the transmission rod 3 cannot move in a straight line. In order to realize the transmission rod 3 driving the moving rod 2 to move in a straight line, a second slide 31 and a second slider 32 are provided. By moving the second slider 32 in the second slide 31, the change in the height of the top end of the transmission rod 3 can be effectively eliminated. Only the change in the horizontal direction of the top end of the transmission rod 3 is transmitted to the moving rod 2, thereby realizing the linear movement of the moving rod 2.
[0040] In one embodiment, see Figure 1 A second guide block 13 is fixedly mounted on the surface of the mounting plate 1 , and the moving rod 2 is slidably sleeved on the second guide block 13 .
[0041] In this embodiment, the number of the second guide block 13 is more than one, and the function of the second guide block 13 is to guide the moving direction of the moving rod 2 and prevent the moving rod 2 from deviating from the moving track.
[0042] In one embodiment, see Figure 1 The cutting device 4 includes a cutting knife 41, a positioning block 42 and a cylinder 43. The cutting knife 41 is connected to the top of the first guide block 11, the positioning block 42 is connected to the moving rod 2, and the cylinder 43 is located above the positioning block 42 and is fixedly connected to the mounting plate 1. The cylinder 43 is used to drive the positioning block 42 and the cutting knife 41 to move downward together.
[0043] In this embodiment, the fixed end of the cylinder 43 is fixedly connected to the mounting plate 1, and the output end of the cylinder 43 is connected to a push block 431. The push block 431 increases the contact area with the filling block 42, making the pushing process more stable.
[0044] It should be noted that a first connecting piece 411 is provided at the top of the cutting knife 41, and a first return spring 412 is connected between the first connecting piece 411 and the top of the first guide block 11 to facilitate the resetting of the cutting knife 41 after cutting; a second return spring 422 is connected between the filling block 42 and the second guide block 13 to facilitate the lateral resetting of the filling block 42.
[0045] In one embodiment, see Figure 1 A sliding hole 22 is formed at the top of the moving rod 2 , and a guide rod 421 is fixedly connected to the top of the compensation block 42 , and the guide rod 421 is slidably sleeved in the sliding hole 22 .
[0046] In this embodiment, a second connecting piece 4211 is also provided on the top of the guide rod 421 , and a third reset spring 423 is connected between the second connecting piece 4211 and the top of the moving rod 2 to facilitate the longitudinal reset of the compensation block 42 .
[0047] In one embodiment, see Figure 2 The first guide block 11 is provided with a cutting channel 111 , and the cutting knife 41 is located directly above the cutting channel 111 .
[0048] In this embodiment, the width of the cutting channel 111 is the same as the width of the cutting blade 41, so that the cutting blade 41 will not deviate during the cutting process, thereby improving the cutting effect of the plastic pipe.
[0049] In one embodiment, see Figure 2, and also includes a driving device 5, which includes a servo motor 51 and a pair of driving wheels 52. The two driving wheels 52 are relatively arranged on the mounting plate 1, and the servo motor 51 is connected to the driving wheels 52. The servo motor 51 is used to drive the two driving wheels 52 to rotate and move the plastic pipe between the two driving wheels 52 toward the first guide block 11.
[0050] In this embodiment, the arc side walls of the driving wheels 52 are all concave, which effectively prevents the plastic pipe from escaping from between the two driving wheels 52 during movement, and the servo motor 51 only drives one driving wheel 52 to rotate, while the other driving wheel 52 rotates following the movement of the plastic pipe.
[0051] Furthermore, in order to prevent the driving wheel 52 from continuing to rotate during the cutting process of the cutting device 4 and causing damage to the equipment, a sensor 14 is provided on the mounting plate 1. When the sensor 14 detects the end of the moving rod 2, the servo motor 51 is turned off and the driving wheel 52 stops rotating.
[0052] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:
[0053] First, according to the required cutting length of the plastic pipe, the staff rotates the screw rod 122 through the hand wheel 1221, and the first slider 121 drives the transmission rod 3 to move, so that the transmission rod 3 selects a suitable through hole 21 for connection, ensuring that the distance between the transmission rod 3 and the cutting channel 111 in the first guide block 11 is the required distance; then, the servo motor 51 is started, and the two driving wheels 52 drive the plastic pipe to pass through the first guide block 11 and move toward the transmission rod 3 until the end of the plastic pipe touches the transmission rod 3; then, the plastic pipe continues to move, the bottom end of the transmission rod 3 is abutted by the plastic pipe and rotates, and the top end of the transmission rod 3 drives the moving rod 2 to move toward the first guide block 11, and the filling block 42 enters between the push block 431 and the first connecting piece 411 as the moving rod 2 moves; finally, the cylinder 43 is started, and the cylinder 43 pushes the push block 431, the filling block 42 and the first connecting piece 411 downward in turn, and the cutting knife 41 passes through the cutting channel 111 downward, thereby realizing the cutting of the plastic pipe.
[0054] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
