Description

Technical Field

[0001] This invention relates to the field of nylon roller can processing technology, and more specifically, to a high-precision CNC machine tool for processing nylon roller cans. Background Technology

[0002] Nylon roller cans, as important industrial components, are widely used in industries such as textiles, printing, papermaking, and logistics. These components are typically made from nylon or its composite materials, cast or extruded into blanks, and then machined to achieve the final dimensional accuracy and surface quality requirements. The diameter of nylon roller cans usually ranges from a few millimeters to several meters. During the casting process, wear on the mold surface or gaps at the joints of mating molds can easily cause burrs to form on the inner wall of the nylon roller can. If nylon roller cans are used in the food, pharmaceutical, or cosmetic industries, these burrs can contaminate the materials, leading to product loss.

[0003] In related technologies, deburring equipment is typically used to remove burrs from the outer wall of nylon roller cans. However, for burrs inside the nylon roller cans, workers usually manually clean them with brushes, which is cumbersome and prone to omissions. Therefore, we propose a high-precision CNC machine tool for processing nylon roller cans. Summary of the Invention

Detailed Implementation

[0035] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0036] like Figures 1-15 As shown, a high-precision CNC machine tool for processing nylon roller cans includes a nylon roller can 1, a processing table 2, a clamping assembly 3, and a cleaning assembly 4. The processing table 2 primarily serves as a mounting and supporting element, providing a carrier for mounting and supporting corresponding components. The clamping assembly 3 is mainly used to clamp the nylon roller can 1, maintaining its stability and facilitating deburring. The cleaning assembly 4 is mainly used to remove burrs from the inner wall of the nylon roller can 1.

[0037] Specifically, such as Figure 1 As shown, the processing table 2 includes a top plate 21 and multiple support columns 22. The multiple support columns 22 are fixedly connected to the bottom of the top plate 21 to support the top plate 21.

[0038] In addition, such as Figure 1 and Figure 2 As shown, the clamping assembly 3 is mounted on the top plate 21. The clamping assembly 3 includes three L-shaped clamping rods 31 and a drive assembly 32. The drive assembly 32 drives the three clamping rods 31 to move radially along the nylon roller can 1, selectively clamping the outer wall of the nylon roller can 1. That is, the three clamping rods 31 can clamp the outer wall of the nylon roller can 1, or they can leave it unclamped. Specifically, before cleaning the burrs on the inner wall of the nylon roller can 1, the drive assembly 32 can be used to move the three clamping rods 31 towards the axis of the nylon roller can 1 to clamp the outer wall and maintain its stability. After the burrs on the inner wall of the nylon roller can 1 are cleaned, the drive assembly 32 can be used to move the three clamping rods 31 away from the axis of the nylon roller can 1, thereby releasing the nylon roller can 1 for easy removal and placement of a new nylon roller can 1.

[0039] Furthermore, if Figure 3As shown, the drive assembly 32 includes a motor 321, a gearbox 322, and a three-jaw chuck 323. The motor 321 is fixedly connected to the top of the top plate 21. The output end of the motor 321 is connected to the gearbox 322, and the output end of the gearbox 322 is fixedly connected to the three-jaw chuck 323. The three-jaw chuck 323 is existing technology, featuring three jaws. Three clamping rods 31 correspond one-to-one with the three jaws on the three-jaw chuck 323, with one end of each clamping rod 31 fixedly connected to the corresponding jaw, and the other end selectively clamping against the outer wall of the nylon roller tank 1. It should be noted that since the axis of the nylon roller tank 1 is horizontal, the other end of the clamping rod 31 can also be horizontally positioned along the axis of the nylon roller tank 1.

[0040] In use, initially, the radius of the circumference of the other ends of the three clamping rods 31 is larger than the radius of the nylon roller can 1. The nylon roller can 1 is then placed between the three clamping rods 31. The three-jaw chuck 323 is then adjusted to move the three jaws towards its center, allowing the other ends of the three clamping rods 31 to move towards the nylon roller can 1 until it is secured. When it is necessary to drive the nylon roller can 1 to rotate, the motor 321 is started. The motor 321, through the gearbox 322, drives the three-jaw chuck 323 to rotate, which in turn drives the nylon roller can 1 to rotate through the three clamping rods 31.

[0041] In addition, such as Figures 1-3 , Figure 5 and Figure 8 As shown, the cleaning assembly 4 is mounted on the top plate 21. The cleaning assembly 4 includes: a moving rod 41, a brush 42, an angle adjustment assembly 43, a distance adjustment assembly 44, and a second drive assembly 45. The moving rod 41 is horizontally arranged along the axial direction of the nylon roller tank 1. The second drive assembly 45 is mounted on the top plate 21 and is fixedly connected to one end of the moving rod 41. The second drive assembly 45 is used to drive the moving rod 41 to move in and out of the nylon roller tank 1 along its axis.

[0042] An angle adjustment component 43 is mounted on the moving rod 41 and connected to the distance adjustment component 44. The distance adjustment component 44 is connected to the brush 42. The angle adjustment component 43 is used to adjust the angle between the distance adjustment component 44 and the brush 42 in the vertical direction so that the distance adjustment component 44 and the brush 42 selectively pass through the opening of the nylon roller tank 1. The distance adjustment component 44 is used to adjust the distance between the brush 42 and the inner wall of the nylon roller tank 1.

[0043] Specifically, such as Figure 5 , Figure 8 , Figures 13-15As shown, the angle adjustment assembly 43 includes: a first rotating shaft 431, a second rotating shaft 432, a first sprocket 433, a second sprocket 434, a chain 435, a second motor 436, and a rotating base 437. The first rotating shaft 431 and the second rotating shaft 432 are rotatably connected to the moving rod 41 at a parallel interval. The axes of both the first rotating shaft 431 and the second rotating shaft 432 can be horizontally set and perpendicular to the axis of the nylon roller tank 1. The first rotating shaft 431 passes through the moving rod 41. The first sprocket 433 and the second sprocket 434 are respectively fixedly connected to one end of the first rotating shaft 431 and the second rotating shaft 432. The chain 435 is drively connected to the first sprocket 433 and the second sprocket 434. The rotating base 437 is fixedly connected to the other end of the first rotating shaft 431. The second motor 436 is fixedly connected to the moving rod 41, and the output end of the second motor 436 is fixedly connected to the second rotating shaft 432.

[0044] When in use, starting motor 2 436 will cause the rotating shaft 2 432 to rotate. The rotation of rotating shaft 2 432 will be transmitted through sprocket 2 434, chain 435, sprocket 1 433 and rotating shaft 1 431 to drive rotating seat 437 to rotate. This will drive distance adjustment component 44 and brush 42 to rotate in the vertical plane, thereby adjusting the angle of distance adjustment component 44 and brush 42 in the vertical direction, so that distance adjustment component 44 and brush 42 can pass smoothly through the mouth of nylon roller tank 1.

[0045] Furthermore, if Figure 8 and Figure 11 As shown, the distance adjustment assembly 44 includes a mounting plate 441, a cylinder 442, a mounting base 443, and a connecting plate 444. The mounting plate 441 is fixedly connected to the rotating seat 437, and the cylinder 442 is fixedly connected to the mounting plate 441, with the extension / retraction direction of the cylinder 442 in the initial state being the same as the axial direction of the moving rod 41. The extension / retraction end of the cylinder 442 is fixedly connected to the mounting base 443, and the mounting base 443 is fixedly connected to the connecting plate 444. The brush 42 is fixedly connected to the side of the connecting plate 444 away from the mounting base 443.

[0046] It should be noted that, since the opening of the nylon roller tank 1 is smaller than its internal dimensions, to allow the cleaning component 4 to smoothly enter the interior of the nylon roller tank 1, the cylinder 442 can be initially positioned horizontally, with its extension / retraction direction aligned with the axial direction of the moving rod 41. This minimizes the volume of the cleaning component 4 at the opening of the nylon roller tank 1. After the cylinder 442 is fully inside the nylon roller tank 1, the angle of the cylinder 442 is adjusted using the angle adjustment component 43. Once the angle of the cylinder 442 is adjusted, it is activated, extending its extension end. This extension, transmitted through the mounting base 443 and the connecting plate 444, drives the brush 42 towards the inner wall of the nylon roller tank 1, thereby enabling the brush 42 to clean the inner wall of the nylon roller tank 1.

[0047] In addition, such as Figure 13 and Figure 15 As shown, the connecting plate 444 has an L-shaped structure and is made of a super-elastic material. The super-elastic material can withstand large recoverable deformation. Since the inner circumferential wall of the nylon roller tank 1 has an arc-shaped structure and the brush 42 has a flexible structure, this design allows the connecting plate 444 to better adapt to the shape of the inner circumferential wall of the nylon roller tank 1, thereby allowing the brush 42 to better clean the inner circumferential wall of the nylon roller tank 1.

[0048] Specifically, the connecting plate 444 includes a first bending portion 4441 and a second bending portion 4442. The second bending portion 4442 is arranged parallel to and spaced apart from the mounting base 443. The two ends of the first bending portion 4441 are fixedly connected to the end of the mounting base 443 away from the moving rod 41 and the end of the second bending portion 4442 away from the moving rod 41, respectively. This allows for the allowance of deformation space for the second bending portion 4442. The brush 42 is fixedly connected to the second bending portion 4442.

[0049] Furthermore, such as Figure 15 As shown, the end of the second bend 4442 away from the first bend 4441 extends toward the moving rod 41 and beyond the axis of the moving rod 41. This increases the adhesion area of ​​the brush 42 on the second bend 4442. Furthermore, since the axis of the moving rod 41 is collinear with the axis of the nylon roller tank 1, by setting the second bend 4442 to cover the axis of the moving rod 41, that is, by setting the brush 42 to cover the axis of the moving rod 41, the brush 42 can cover the center of the bottom wall of the nylon roller tank 1, thereby cleaning the inner wall of the nylon roller tank 1 more thoroughly.

[0050] In addition, such as Figures 2-4 As shown, a movable hole 211 is provided on the top plate 21 along the axial direction of the nylon roller tank 1. The movable hole 211 can play a guiding and avoidance role.

[0051] Drive assembly 2 45 includes motor 3 451, gearbox 2 452, two fixed seats 1 453, screw 1 454, nut seat 1 455, and motor 456. The two fixed seats 1 453 are fixedly connected to the bottom of the top plate 21 and are respectively located on both sides of the moving hole 1 211, thus avoiding interference with components above the top plate 21. Both ends of the screw 1 454 are rotatably connected to the two fixed seats 1 453, and one end of the screw 1 454 extends out of the corresponding fixed seat 1 453 and is fixedly connected to the output shaft of motor 456. The axial direction of the screw 1 454 is the same as the axial direction of the nylon roller tank 1, and motor 456 is fixedly connected to the bottom of the top plate 21. Motor 3 451 is located on the upper side of top plate 21. Nut seat 1 455 is threadedly connected to screw 1 454, and the top of nut seat 1 455 is fixedly connected to motor 3 451 through moving hole 1 211. The output shaft of motor 3 451 is connected to gearbox 2 452, and the output end of gearbox 2 452 is connected to moving rod 41.

[0052] When it is necessary to adjust the axial position of the brush 42 in the nylon roller tank 1, the motor 456 is started. The motor 456 drives the screw 454 to rotate, which causes the nut seat 455 to move axially along the screw 454. The movement of the nut seat 455, in turn, drives the brush 42 to move axially along the nylon roller tank 1 through the transmission of the motor 451, the reduction gearbox 452, the moving rod 41, the angle adjustment component 43, and the distance adjustment component 44. This allows for a more comprehensive cleaning of the inner wall of the nylon roller tank 1. It should be noted that during the cleaning process, the bottom wall of the nylon roller tank 1 can be cleaned first, and then the inner circumferential wall of the nylon roller tank 1 can be cleaned from the inside out. This sequential cleaning can reduce the occurrence of missed areas.

[0053] The above cleaning method mainly involves keeping the brush 42 stationary while using the clamping assembly 3 to rotate the nylon roller tank 1, thereby cleaning the inner wall of the nylon roller tank 1. Alternatively, the motor 3 451 can be started simultaneously, driving the brush 42 to rotate via the gearbox 2 452, the moving rod 41, the angle adjustment assembly 43, and the distance adjustment assembly 44. The direction of the brush 42's rotation is opposite to the direction of the nylon roller tank 1's rotation, which speeds up the cleaning of the inner wall of the nylon roller tank 1.

[0054] In addition, such as Figure 5 , Figure 8 , Figure 10 and Figure 11As shown, a flow channel 411 is formed inside the moving rod 41 along its length. An inlet 412 and an outlet 413, communicating with the flow channel 411, are respectively formed at both ends of the moving rod 41. The inlet 412 is located at the end closer to the brush 42, and the outlet 413 is located at the end farther from the brush 42. The outlet 413 can be connected to an existing external vacuum cleaner. A cavity 4431 is formed inside the mounting base 443. Multiple suction holes 4432 communicating with the cavity 4431 and one dust outlet 4433 communicating with the cavity 4431 are formed on the mounting base 443. A retractable corrugated pipe 5 connects the dust outlet 4433 to the inlet 412.

[0055] During use, while the brush 42 cleans the inner wall of the nylon roller tank 1, an external vacuum cleaner is activated to draw air through the discharge port 413, creating negative pressure within the flow channel 411. This allows the cleaned burrs to enter the cavity 4431 through the suction holes 4432, then through the dust outlet 4433 and the corrugated pipe 5 into the flow channel 411, and finally exit through the discharge port 413. This reduces the adhesion and residence time of the cleaned burrs on the nylon roller tank 1. The multiple suction holes 4432 provide a more comprehensive suction experience, allowing for the absorption of cleaned burrs from multiple directions, which is beneficial for burr collection and processing.

[0056] In addition, such as Figures 1-4 and Figure 6 As shown, a second movable hole 212 is provided on the top plate 21 along the axial direction of the nylon roller tank 1. The second movable hole 212 can play a guiding and avoidance role.

[0057] The high-precision CNC machine tool also includes a support and centering assembly 6. The support and centering assembly 6 includes: a support ring 61, a connecting rod 62, a second screw 63, a second nut seat 64, a fifth motor 65, and two second fixed seats 66. The two second fixed seats 66 are fixedly connected to the bottom of the top plate 21, and are respectively positioned on both sides of the second moving hole 212, thus reducing interference with the upper components of the top plate 21. Both ends of the second screw 63 are rotatably connected to the two second fixed seats 66, and one end of the second screw 63 protrudes from the corresponding second fixed seat 66 and is fixedly connected to the output shaft of the fifth motor 65. The axial direction of the second screw 63 is the same as the axial direction of the nylon roller tank 1. The fifth motor 65 is fixedly connected to the bottom of the top plate 21. Connecting rod 62 is located on the upper side of top plate 21. Nut seat 64 is threaded onto screw rod 63, and the top of nut seat 64 is fixedly connected to the bottom of connecting rod 62 through moving hole 212. The top of connecting rod 62 is fixedly connected to support ring 61. The inner diameter of support ring 61 is the same as the outer diameter of the opening of nylon roller tank 1. Support ring 61 selectively supports the opening of nylon roller tank 1. It should be noted that support ring 61 is concentrically arranged with three-jaw chuck 323.

[0058] In use, after the clamping assembly 3 clamps the outer wall of the nylon roller can 1, and before the brush 42 extends into the inner wall of the nylon roller can 1, the motor 65 is started. The motor 65 will drive the screw 63 to rotate. The rotation of the screw 63 will drive the nut seat 64 to move along the axial direction of the screw 63. The movement of the nut seat 64 will then drive the support ring 61 to move toward the opening of the nylon roller can 1 through the connecting rod 62, until the support ring 61 engages with the opening of the nylon roller can 1, thereby supporting and limiting the opening of the nylon roller can 1, and thus making the nylon roller can 1 more stable when rotating.

[0059] Furthermore, such as Figure 9 As shown, a limiting ring 67 is provided inside the support ring 61. The inner diameter of the limiting ring 67 is less than or equal to the inner diameter of the opening of the nylon roller can 1, and the outer diameter of the limiting ring 67 is the same as the inner diameter of the support ring 61. This allows the limiting ring 67 to limit the opening of the nylon roller can 1, preventing it from moving along its axial direction and further improving its stability. Furthermore, a sanding plate 68 that mates with the opening of the nylon roller can 1 is fixedly connected to the limiting ring 67. During the rotation of the nylon roller can 1, the sanding plate 68 can be used to polish the opening, thereby improving its flatness.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
