Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe processing equipment, in particular to a plastic pipe chamfering mechanism for chamfering a pipe mouth of a plastic pipe. Background Art

[0002] Plastic pipe chamfering is a process in the pipe processing, which involves chamfering the pipe mouth to facilitate the subsequent connection and assembly of the plastic pipe, so as to improve the sealing and firmness of the pipe connection. For example, the chamfering of the pipe mouth of plastic pipes such as PVC, PPR, and PE. The pipe chamfering process equipment is usually connected and set upstream of the pipe packaging process equipment. After the chamfering of the plastic pipe mouth is completed, it enters the next packaging process equipment, and the packaging mechanism packages the plastic pipe with the chamfered pipe mouth to improve the transportation efficiency of the pipe and protect the pipe from damage during transportation. Since the downstream packaging mechanism usually packages a bundle of plastic pipes at a time, the packaging operation time is shorter than the operation time of pipe chamfering, so the efficiency is higher, which puts higher efficiency requirements on the pipe chamfering equipment. In addition, since different application scenarios require plastic pipes of different specifications and sizes, and the actual application environment of the pipe has different requirements for the chamfered parts of the pipe mouth, there is an urgent need for a plastic pipe chamfering mechanism that can be suitable for different sizes and specifications and is suitable for simultaneously chamfering the inside and outside of the pipe mouth of the plastic pipe.

[0037] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0038] Please refer to Figure 1 , Figure 6As shown, an embodiment of the utility model provides a plastic pipe chamfering mechanism 100, whose structural components mainly include a clamping component 1, a cutting component 2, a moving component 6, a lifting component 5, a first adjusting component 3, a second adjusting component 4 and a control component 7.

[0039] Combination Figure 1 , Figure 3 As shown, the clamping assembly 1 is used to clamp the plastic pipe 101. The clamping assembly 1 may include a bracket 11, a lower clamping jaw 12 fixed on the bracket 11, an upper clamping jaw 13 located on the upper side of the lower clamping jaw 12, and a clamping cylinder 14 disposed on the bracket 11 and connected to the upper clamping jaw 13. During operation, the plastic pipe 101 to be processed can be placed on the lower clamping jaw 12 manually or by a handling manipulator, and the upper clamping jaw 13 is driven downward by the clamping cylinder 14, and the upper clamping jaw 13 and the lower clamping jaw 12 together clamp and fix the plastic pipe 101.

[0040] In one embodiment of the utility model, the material of the plastic pipe 101 can be PVC, PPR, PE, etc. The shape of the lower clamping jaw 12 can be V-shaped or semicircular, and its shape can be adapted to the outer shape of the circular plastic pipe 101. The lower clamping jaw 12 can be constructed with a positioning groove or a positioning hole so that the plastic pipe 101 can be placed in the positioning groove or the positioning hole of the lower clamping jaw 12. The shapes of the upper clamping jaw 13 and the lower clamping jaw 12 can match each other, and can be two semi-circular opposed clamping. It can also be two annular parts that overlap or penetrate each other, that is, the inner ring and the outer ring are nested with each other. When the plastic pipe 101 is clamped, the inner ring and the outer ring move relative to each other and are displaced, thereby clamping the plastic pipe 101 between the inner ring and the outer ring, and there is no specific limitation.

[0041] Combination Figure 2 , Figure 4 and Figure 5 As shown, the cutting assembly 2 includes a cutter seat 21, a cutter disc 22 rotatably disposed on the cutter seat 21, a power module 23 for driving the cutter disc 22 to rotate, and an inner chamfering cutter 24 and an outer chamfering cutter 25 radially movably disposed on the cutter disc 22. The cutter disc 22 has a rotation center 221, and the moving path of the inner chamfering cutter 24 and the moving path of the outer chamfering cutter 25 intersect at the rotation center 221.

[0042] Specifically, the tool holder 21 has a rotatable input shaft 211 and an output shaft 212, the power module 23 includes a rotating motor 231, a driving wheel 232, a driven wheel 233 and a transmission belt 234, the driving wheel 232 is installed on the rotating motor 231, the driven wheel 233 is installed on the input shaft 211 of the tool holder 21, the transmission belt 234 is connected between the driving wheel 232 and the driven wheel 233, and the tool disc 22 is installed on the output shaft 212 of the tool holder 21.

[0043] In some embodiments, the rotating motor 231 may be a speed-regulating motor or a servo motor, without limitation.

[0044] During operation, the driving wheel 232 is driven to rotate by the rotating motor 231, and the torque output by the rotating motor 231 is transmitted to the driven wheel 233 through the transmission belt 234. The driven wheel 233 drives the input shaft 211 of the cutter seat 21 to rotate, and then drives the output shaft 212 of the cutter seat 21 to rotate, so that the cutter disc 22 rotates around the rotation center 221. The inner chamfering cutter 24 and the outer chamfering cutter 25 on the cutter disc 22 respectively move in a circular trajectory to perform a cutting action.

[0045] Since the inner chamfering knife 24 and the outer chamfering knife 25 are respectively movably arranged on the cutter disc 22 in the radial direction, the distance between the inner chamfering knife 24 and the outer chamfering knife 25 and the rotation center 221 of the cutter disc 22 can be adjusted to be suitable for cutting plastic pipes 101 with different wall thicknesses.

[0046] The first adjustment component 3 is disposed on the cutter disc 22 and is used to adjust the distance between the inner chamfering knife 24 and the rotation center 221; the second adjustment component 4 is disposed on the cutter disc 22 and is used to adjust the distance between the outer chamfering knife 25 and the rotation center 221. The distance between the inner chamfering knife 24 on the cutter disc 22 and the rotation center 221 of the cutter disc 22 is adjusted by the first adjustment component 3, and the distance between the outer chamfering knife 25 on the cutter disc 22 and the rotation center 221 of the cutter disc 22 is adjusted by the second adjustment component 4. The difference between the two distances is the wall thickness value of the plastic pipe 101, which can be suitable for chamfering plastic pipes 101 with different wall thicknesses, and can simultaneously chamfer the inner and outer sides of the pipe mouths of plastic pipes 101 with different specifications.

[0047] Specifically, the first adjustment assembly 3 includes a first adjustment member 31 slidably disposed on the cutter disc 22, a first adjustment screw 32 rotatably disposed on the cutter disc 22 and threadedly connected to the first adjustment member 31, and the inner chamfering knife 24 is mounted on the first adjustment member 31. The second adjustment assembly 4 includes a second adjustment member 41 slidably disposed on the cutter disc 22, a second adjustment screw 42 rotatably disposed on the cutter disc 22 and threadedly connected to the second adjustment member 41, and the outer chamfering knife 25 is mounted on the second adjustment member 41.

[0048] The cutter disc 22 may be provided with two radially extending movable grooves 222 , the two movable grooves 222 intersect at a rotation center 221 of the cutter disc 22 , and the first adjusting member 31 and the second adjusting member 41 may be slidably fitted in the movable grooves 222 , respectively.

[0049] When replacing plastic pipes 101 of different wall thicknesses and sizes for chamfering operations, the distance from the inner chamfering knife 24 to the rotation center 221 can be adjusted by rotating the first adjusting screw 32, and the distance from the outer chamfering knife 25 to the rotation center 221 can be adjusted by rotating the second adjusting screw 42. The difference between the two distances is the wall thickness value of the plastic pipe 101.

[0050] It should be noted that when the plastic pipes 101 of different specifications and sizes are chamfered, since the plastic pipes 101 of different diameters are processed before and after, after the processing of the previous plastic pipe 101 is completed, the center of the pipe mouth of the latter plastic pipe 101 and the rotation center 221 of the cutter disc 22 will deviate after the plastic pipe 101 of different sizes is replaced and clamped and fixed by the clamping assembly 1, and the rotation center 221 of the cutter disc 22 and the center of the pipe mouth of the latter plastic pipe 101 need to be repositioned and aligned. This is because after the plastic pipes 101 of different diameters are replaced and clamped and fixed by the clamping assembly 1, the center of the pipe mouth of the plastic pipe 101 generally does not deviate in the left-right direction, so there is no need to adjust the rotation center 221 of the cutter disc 22 in the left-right direction. Since the diameter of the latter plastic pipe 101 is different from that of the former plastic pipe, the center of the pipe mouth of the plastic pipe 101 usually deviates in the height direction. Generally, when the chamfering operation is performed from a plastic pipe 101 with a smaller diameter to a plastic pipe 101 with a larger diameter, the center of the pipe opening of the plastic pipe 101 with a larger diameter is higher than the center of the pipe opening of the plastic pipe 101 with a smaller diameter, and the rotation center 221 of the cutter disc 22 needs to be moved up so that it can be positioned and aligned with the center of the pipe opening of the plastic pipe 101 to be processed, so as to facilitate the subsequent chamfering operation. Similarly, when the chamfering operation is performed from a plastic pipe 101 with a larger diameter to a plastic pipe 101 with a smaller diameter, the center of the pipe opening of the plastic pipe 101 with a smaller diameter is lower than the center of the pipe opening of the plastic pipe 101 with a larger diameter, and the rotation center 221 of the cutter disc 22 needs to be moved down so that it can be positioned and aligned with the center of the pipe opening of the plastic pipe 101 to be processed, so as to facilitate the subsequent chamfering operation.

[0051] In order to solve the above problems, in one embodiment of the utility model, the lifting component 5 and the moving component 6 are used to drive the tool holder 21 to rise and fall and move forward respectively, so that the rotation center 221 of the cutter disc 22 is quickly aligned with the center of the pipe mouth of the plastic pipe 101, and the center of the pipe mouth of the plastic pipe 101 to be processed can be quickly positioned and found; the operating efficiency is higher and the versatility is better.

[0052] Combination Figure 1 , Figure 3As shown, the lifting assembly 5 is used to drive the knife seat 21 to lift and lower, so as to align the rotation center 221 of the knife disc 22 with the center of the pipe mouth of the plastic pipe 101. The moving assembly 6 is used to drive the knife seat 21 to move forward, so that the inner chamfering knife 24 and the outer chamfering knife 25 on the knife disc 22 extend into the inner and outer sides of the pipe mouth of the plastic pipe 101, so as to facilitate the subsequent chamfering operation of the plastic pipe 101.

[0053] The lifting assembly 5 includes a base plate 51 , a lifting motor 52 disposed on the base plate 51 , and a screw transmission module 53 disposed on the base plate 51 and transmission-connected to the lifting motor 52 .

[0054] In some embodiments, the lifting motor 52 may be a servo motor, which has higher precision, and is not specifically limited thereto.

[0055] The screw transmission module 53 is configured to transmit the power of the lifting motor 52 to the base plate 61 of the moving assembly 6 so as to drive the base plate 61 to rise and fall. Specifically, the screw transmission module 53 includes a lifting screw 531 that is transmission-connected to the lifting motor 52, and a lifting nut 532 that is slidably fitted on the lifting screw 531, and the lifting nut 532 is fixed to the base plate 61.

[0056] During operation, the lifting motor 52 drives the lifting screw 531 to rotate, so that the lifting nut 532 drives the base plate 61 to rise or fall together, thereby realizing the lifting action.

[0057] In order to improve the stability of the base plate 61 during lifting, a guide structure is provided between the base plate 51 and the base plate 61, and the guide structure includes a guide shaft 533 and a guide sleeve 534. The upper end of the guide shaft 533 is fixedly connected to the base plate 61, and the lower end of the guide shaft 533 is slidably fitted in the guide sleeve 534, and the guide sleeve 534 is installed on the base plate 51. During operation, the lifting motor 52 drives the lifting screw 531 to rotate, and the lifting nut 532 drives the base plate 61 to rise or fall together. During the lifting and lowering of the base plate 61 relative to the base plate 51, the guide shaft 533 slides relative to the guide sleeve 534.

[0058] The moving assembly 6 includes a base plate 61 , a moving plate 62 movably arranged on the base plate 61 along the front-rear direction, a pushing cylinder 63 arranged on the base plate 61 and transmission-connected to the moving plate 62 , and the tool holder 21 and the power module 23 are arranged on the moving plate 62 .

[0059] Specifically, a sliding module 64 is provided between the base plate 61 and the movable plate 62, and the sliding module 64 includes a slide rail 641 provided on one of the base plate 61 and the movable plate 62, and a slider 642 provided on the other of the base plate 61 and the movable plate 62, and the slide rail 641 and the slider 642 are slidably matched. In one embodiment of the utility model, the relative movement structure between the movable plate 62 and the base plate 61 is not limited to the structure of the slide rail and the slider, but can also be a structure of the slide member and the slide groove, which is not specifically limited.

[0060] Combination Figure 6 As shown, the control component 7 may include a controller 71 and a touch screen 72. The controller 71 may be controlled and connected to the rotating motor 231 of the power module 23, the lifting motor 52 of the lifting component 5, and the pushing cylinder 63 of the moving component 6, respectively. The touch screen 72 may be connected to the controller 71 in communication. The touch screen 72 may be used as a module with both input and output functions, may receive information input by the user, provide a human-machine interface for interaction with the user, and may display the program instructions pre-stored in the controller 71, the parameters of the rotating motor 231, the lifting motor 52, and the pushing cylinder 63, as well as the wall thickness parameters of plastic pipes of different specifications and sizes, the height difference between the rotating center 221 of the cutter head 22 and the center of the pipe mouth of plastic pipes of different diameters (usually an absolute value), etc. The controller 71 may receive, store, and execute the program instructions edited and input by the user through the touch screen 72. For example, the user may input the processing program instructions of plastic pipes of different diameters and wall thicknesses through the touch screen 72, and the processing program instructions of the parameter values ​​of plastic pipes of different diameters and wall thicknesses may be stored and executed in the controller 71. For example, when processing a plastic pipe with a diameter of 20 mm and a wall thickness of 2 mm, after the plastic pipe is clamped and fixed by the clamping assembly 1, there is a height above the ground between the center of the pipe mouth of the plastic pipe and the ground, which can be stored in the controller 71 as an initial height value. The controller 71 can also pre-store the start and stop instructions and speed parameters of the rotating motor 231, the start and stop instructions and speed parameters of the lifting motor 52, the start and stop instructions of the pushing cylinder 63, the initial value of the rotation center 221 of the cutter disc 22 from the ground, and the initial height value above the ground corresponding to the processing of the plastic pipe with a diameter of 20 mm and a wall thickness of 2 mm. When switching to processing plastic pipes with a diameter of 30 mm and a wall thickness of 4 mm, there is a difference between the distance from the ground between the center of the pipe mouth of the plastic pipe with a diameter of 30 mm and a wall thickness of 4 mm and the distance from the ground between the center of the pipe mouth of the plastic pipe with a diameter of 20 mm and a wall thickness of 2 mm, for example, 10 mm. At this time, the controller 71 can store an absolute value of the height difference of 10 mm. Therefore, when processing plastic pipes with a diameter of 30 mm and a wall thickness of 4 mm, the controller 71 only needs to send a control command to the lifting motor 52 to move it up by 10 mm to achieve the accurate positioning of the rotation center 221 of the cutter disc 22 and the center of the pipe mouth of the plastic pipe to be processed.

[0061] In some embodiments, the controller 71 may be a PLC controller or a computer, and the touch screen 72 may be replaced by an input module and an output module, such as a keyboard or an operation panel and a display, without specific limitation.

[0062] In addition, the wall thickness adjustment of processing a plastic pipe with a diameter of 20 mm and a wall thickness of 2 mm to processing a plastic pipe with a diameter of 30 mm and a wall thickness of 4 mm is adjusted by the first adjustment component 3 and the second adjustment component 4 on the cutter head 22. As mentioned above, when changing a plastic pipe 101 with different wall thicknesses and sizes for chamfering, the distance from the inner chamfering cutter 24 to the rotation center 221 can be adjusted by rotating the first adjustment screw 32, and the distance from the outer chamfering cutter 25 to the rotation center 221 can be adjusted by rotating the second adjustment screw 42. The difference between the two distances is the wall thickness value of the plastic pipe 101. The wall thickness value of 2 mm can be adjusted first, and then the processing program corresponding to the plastic pipe of different diameters can be switched through the touch screen 72.

[0063] In one embodiment of the utility model, the working principle of the plastic pipe chamfering mechanism 100 is implemented as follows:

[0064] After the plastic pipe 101 is placed in the clamping assembly 1 and clamped and fixed, the user can adjust the distance between the inner chamfering knife 24 and the rotation center 221 by rotating the first adjusting screw 32, and adjust the distance between the outer chamfering knife 25 and the rotation center 221 by rotating the second adjusting screw 42. The difference between the two distances is the wall thickness value of the plastic pipe 101 to be processed; then the user can select the control instruction program corresponding to the processing of the plastic pipe of the current diameter and wall thickness through the touch screen 72, so that the controller 71 controls the lifting motor 5 The cutter disc 22 is driven to move up or down to a set height value, so that the rotation center 221 of the cutter disc 22 and the center of the pipe mouth of the plastic pipe 101 are quickly positioned and found, and then the controller 71 controls the push cylinder 63 of the moving assembly 6 to drive the cutter seat 21 to move forward, so that the inner chamfering knife 24 and the outer chamfering knife 25 on the cutter disc 22 extend into the inner and outer sides of the pipe mouth of the plastic pipe 101, and controls the rotation motor 231 of the power module 23 to rotate, and drives the cutter disc 22 to rotate, so as to realize the simultaneous chamfering of the inner and outer sides of the pipe mouth of the plastic pipe 101.

[0065] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
