Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: Figure 1-6 As shown, this utility model provides a polyethylene pipe processing and forming device, including a box body 1. The box body 1 is provided with a conveying mechanism 11 inside. The top of the box body 1 is fixedly installed with a shell 12. The shell 12 is provided with a saw blade 13 inside. The front side of the box body 1 is provided with an exhaust fan 2 and a collection box 21. The fan pipe of the exhaust fan 2 is fixedly connected to the collection box 21. The top and rear sides of the collection box 21 are both fixedly installed with suction pipes 22. The two suction pipes 22 are both fixedly installed with suction hoods 23 on the side away from the collection box 21. The suction hoods 23 are fixedly connected to the box body 1. One suction hood 23 is located at the top and the other at the bottom. The right side of the box body 1 is provided with a support plate 3. The top edge of the support plate 3 is fixedly installed with a support seat 31. The middle of the support seat 31 is rotatably installed with a hollow shaft 32. The outside of the hollow shaft 32 is fixedly installed with a large gear 33. The top of the support seat 31 is provided with a first rotating shaft 34. One end of the first rotating shaft 34 is fixedly installed with a small gear 35 that meshes with the large gear 33.
[0020] Two symmetrically distributed fixed plates 30 are fixedly installed on the side of the large gear 33 near the housing 1. Two symmetrically distributed movable plates 36 are provided between the fixed plates 30. An arc-shaped plate 37 is fixedly installed on the inner side of the movable plate 36, and a brush 38 is installed on the inner side of the arc-shaped plate 37. The saw blade 13 can be driven by a drive motor, and then the saw blade 13 is driven to move up and down by a second cylinder. The first rotating shaft 34 is driven by a first motor and is installed on the support base 31. The second rotating shaft 53 is driven by a second motor and is installed on the top of the housing 1. A [missing information - likely a device or component] is installed at the front end of the housing 1. The PLC controller consists of a central processing unit (CPU) module, a memory module, an input / output (I / O) module, a power supply module, a programming device, and a communication interface. Since the PLC controller is existing technology, its principle will not be explained here. Then, the first cylinder 7, the exhaust fan 2, the drive motor, and the second motor are electrically connected to the PLC controller. In actual use, other compatible controllers can also be selected. The pipe cutting method can also be laser cutting or other methods. The collection box 21 is equipped with a pull-out collection box. The exhaust fan 2 and the collection box 21 are placed on the ground.
[0021] Both fixed plates 30 are threaded with threaded rods 6 in the middle. The threaded rods 6 are rotatably connected to the corresponding movable plates 36. Each movable plate 36 has two limiting rods 61 fixedly installed on the side near the fixed plate 30. The limiting rods 61 are slidably connected to the fixed plate 30. The threaded rods 6 are driven by a rotating wheel and are fixed to the fixed plate 30.
[0022] The conveying mechanism 11 includes two horizontal plates 5 and two conveying rollers 51. Two symmetrically distributed fixed seats are fixedly installed on the inner sides of the two horizontal plates 5. The fixed seats are rotatably connected to the corresponding conveying rollers 51. A first bevel gear 52 is fixedly installed at one end of each conveying roller 51. A second bevel gear 55 is meshed with the outer sides of the first bevel gear 52. A sleeve 54 is fixedly installed at the opposite ends of the second bevel gear 55. The sleeve 54 is rotatably connected to the horizontal plates 5. A second rotating shaft 53 is provided through the middle of the sleeve 54. The second rotating shaft 53 is rotatably connected to the housing 1. By setting the second rotating shaft 53, when the second rotating shaft 53 rotates, it drives the sleeve 54 to rotate on the horizontal plates 5. The rotation of the sleeve 54 drives the corresponding second bevel gear 55 to rotate. The rotation of the second bevel gear 55 drives the first bevel gear 52 and the corresponding conveying rollers 51 to rotate, thereby realizing the conveying of the pipe.
[0023] A first cylinder 7 is fixedly installed at both the top and bottom ends of the housing 1. The drive end of the first cylinder 7 passes through the housing 1 and is fixedly connected to the horizontal plate 5. Several annularly distributed limit blocks 71 are fixedly installed on the outside of the second rotating shaft 53. The middle of the sleeve 54 and the second bevel gear 55 are both connected by a sliding groove 72 that works with the limit blocks 71. By setting the first cylinder 7, when it is necessary to cut pipes of different diameters, the first cylinder 7 at the top of the housing 1 drives the corresponding horizontal plate 5 and conveying roller 51 to move downward by a certain distance through the PLC controller. The first cylinder 7 at the bottom of the housing 1 drives the corresponding horizontal plate 5 and conveying roller 51 to move upward, so that the two conveying rollers 51 are in contact with the pipe. When the horizontal plate 5 moves, the sleeve 54 and the second bevel gear 55 slide on the limit blocks 71 on the second rotating shaft 53, thereby realizing the conveying of pipes of different diameters.
[0024] The conveying mechanism 11 also includes a guide rod 9 and a fixing block 91. The guide rod 9 is slidably connected to the horizontal plate 5, and the fixing block 91 is fixedly connected to the guide rod 9 and the inner wall of the box 1. By setting the guide rod 9, the horizontal plate 5 and the conveying roller 51 are more stable when moving.
[0025] A baffle 10 is fixedly installed on one side of the inner wall of the housing 1. The baffle 10 is located on the inner wall of the side of the first bevel gear 52. By setting the baffle 10, the debris generated when the saw blade 13 cuts the pipe is prevented from splashing onto the first bevel gear 52 and the second bevel gear 55, thereby affecting the meshing of the first bevel gear 52 and the second bevel gear 55.
[0026] The length of the top dust cover 23 is less than that of the bottom dust cover 23, by setting
[0027] The sleeve 54 is composed of a large-diameter cylinder and a small-diameter cylinder, which allows for smoother movement of the horizontal plate 5 and the conveying roller 51 to the sides or to the center.
[0028] In practical use, a conveying mechanism 11 can be added to the support plate 3, or a fixing device can be used to fix pipes of different diameters. However, it should be noted that when the pipe needs to be started forward, the fixing device does not restrict the movement of the pipe. If it is added, a PLC controller or other compatible controller can be installed on the support base 31, and then the first motor can be electrically connected to the PLC controller.
[0029] Working principle: In actual use, the PLC controller controls the conveying mechanism 11 to convey and stop, and the rotation and downward movement of the saw blade 13. At the same time, it controls the start of the exhaust fan 2 and the second motor. The pipe to be processed enters from the feed port on the left side of the box 1, and is then conveyed by the conveying roller 51 in the conveying mechanism 11. When the required cutting position of the pipe is below the saw blade 13, the conveying mechanism 11 stops conveying, and then the saw blade 13 cuts. The debris generated during the pipe cutting is sucked into the collection box 21 through the dust hood 23 and the dust suction pipe 22 by the start of the exhaust fan 2.
[0030] After the pipe is cut, the conveying mechanism 11 continues to convey the cut pipe forward and the pipe exits from the discharge port on the right side of the box 1. As the cut pipe moves forward, the first motor starts, which drives the first rotating shaft 34 and the small gear 35 to rotate. The small gear 35 rotates the large gear 33 and the hollow shaft 32 to rotate. The large gear 33 rotates and drives the fixed plate 30, the moving plate 36, the arc plate 37 and the brush 38 to clean the small amount of debris remaining on the surface of the pipe. The cleaned debris will enter the collection box 21 under the action of the dust hood 23, the dust suction pipe 22 and the exhaust fan 2.
[0031] Due to continuous conveying, the cleaned pipes pass through the hollow shaft 32, and the cut pipes are then collected. When cleaning pipes of different diameters is required, the wheel on the threaded rod 6 is rotated, causing the threaded rod 6 to rotate. The moving plate 36, limited by the limiting rod 61, moves the threaded rod 6, driving the moving plate 36, the arc-shaped plate 37, and the brush 38 to move, thus achieving cleaning of pipes of different diameters. When the collection box 21 is full of debris, the collection container on the collection box 21 is pulled out, and the debris is then emptied.
[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
