Description

Technical Field

[0001] This invention relates to the technical field of pipe fitting marking, specifically to an automatic laser engraving and screen printing machine. Background Technology

[0002] In automotive hoses, markings such as installation location and specifications are necessary for easy connection. This allows assembly and maintenance personnel to select the appropriate hose for installation and ensures proper placement based on the location markings.

[0003] Currently, due to their small size and insufficient dimensions, it is difficult to mark automotive hoses on the market. In the traditional processing, the markings need to be manually processed on the surface of the hose. Furthermore, since the hose is cylindrical, the markings need to be rotated continuously, which is not only inconvenient, but also makes it easy for the starting point of the markings on each hose to be determined manually. This can easily lead to inconsistent marking standards, resulting in the markings on the hoses shifting and affecting their accuracy. Consequently, this can lead to improper installation after installation, posing a safety hazard. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention aims to provide an automatic laser engraving and screen printing machine. This machine features a turntable with several clamping positions, and a screen printing assembly is located beside the turntable. The clamping positions are used to mount the tubing to be processed, ensuring the uniformity and accuracy of the tubing processing position, guaranteeing consistent marking standards, and ensuring the quality of tubing processing. This avoids problems with improper installation later on. Simultaneously, the rotation of the turntable causes each tubing to pass through the screen printing assembly, and an auxiliary drive assembly rotates the clamping positions, allowing the tubing to also rotate. This, in conjunction with the screen printing assembly, enables the marking to be printed on the outer surface of the cylindrical tubing, achieving automated processing and making processing more convenient.

[0005] The specific technical solution is as follows:

[0006] Automatic laser engraving and screen printing machines have the following characteristics, including:

[0007] The frame has a turntable that rotates in a vertical plane rotatably mounted on one side. Several clamping positions are arranged in a circular array on the outer edge of the turntable.

The feeding assembly is located on one side of the turntable and at the end of the clamping shaft opposite to the driven wheel. The feeding assembly includes a conveyor belt, a feeding rack, and a pusher rack. The conveyor belt is located on the side of the machine frame and one end extends to the turntable. The feeding rack is located at the end of the conveyor belt extending to the turntable and has a feeding groove. When the turntable rotates, the feeding groove is aligned with the axial direction of the clamping shaft of each clamping position. The pusher rack is located on the side of the feeding rack opposite to the turntable, and the pusher head of the pusher rack selectively extends into the feeding groove.

[0014] The aforementioned automatic laser engraving screen printing machine further includes a feeding component. Along the rotation direction of the turntable, the feeding component is located beside the turntable and behind the screen printing component. The feeding component includes a feeding slide frame and grippers. The feeding slide frame is mounted on the frame and moves back and forth along the axial direction of the turntable, and the grippers are mounted on the feeding slide frame.

[0015] The aforementioned automatic laser engraving and screen printing machine further includes an auxiliary support frame, which comprises a support rod, an auxiliary telescopic device, and a pressure roller. One end of the support rod is mounted on the machine frame and extends out of the turntable along the axial direction. The auxiliary telescopic device is mounted on the end of the support rod that extends out of the turntable and is located below the screen printing frame. The auxiliary telescopic device is arranged radially along the turntable and is located on both sides of the clamping position along with the scraper. The pressure roller is mounted on the telescopic shaft of the auxiliary telescopic device and moves towards or away from the clamping position.

[0016] The aforementioned automatic laser engraving and screen printing machine further includes a positioning component. Along the rotation direction of the turntable, the positioning component is located in front of the screen printing component. The positioning component includes a mounting block, a positioning driver, and a pressure block. One end of the mounting block is mounted on the frame and arranged radially along the turntable. The positioning driver is mounted on the mounting block. The pressure block is mounted on the telescopic shaft of the positioning driver and moves towards or away from the clamping position along the axial direction of the turntable.

[0017] The aforementioned automatic laser engraving and screen printing machine further includes a feeding adjustment component, which is located below the feeding assembly. The feeding adjustment component includes a mounting plate, a sliding plate, a lifting plate, an adjusting rod, and a guide rod. The mounting plate is horizontally arranged and fixed to the frame on one side. A sliding plate is slidably mounted on the mounting plate along the axial direction of the turntable. A guide hole is opened on the sliding plate in the vertical direction, and a guide rod passes through the guide hole. A lifting plate is mounted on the upper end of the guide rod, and the lifting plate is arranged parallel to the mounting plate and the sliding plate. The feeding assembly is mounted on the lifting plate. An adjusting rod parallel to the guide rod is also provided between the lifting plate and the sliding plate. The upper end of the adjusting rod is rotatably mounted on the bottom of the lifting plate, and the lower end of the adjusting rod is threadedly connected to the sliding plate.

[0018] In the aforementioned automatic laser engraving and screen printing machine, a plurality of strip-shaped sliding holes are provided on the mounting plate along the axial direction of the turntable. The plurality of sliding holes are respectively aligned with the guide rod and the adjusting rod in the vertical direction. The lower end of the guide rod passes through the guide hole and extends into the corresponding sliding hole. The lower end of the adjusting rod is threadedly connected to the sliding plate and extends to the bottom of the sliding plate and into the corresponding sliding hole.

[0019] The positive effects of the above technical solution are:

[0020] The aforementioned automatic laser engraving and screen printing machine, by setting a screen printing component above a rotating turntable in a vertical plane, and having several clamping positions on the turntable that rotate under the action of an auxiliary drive component, uses these clamping positions to mount the rubber tubes to be processed. This ensures the uniformity and accuracy of the rubber tube processing position, guarantees the consistency of the marking standards, ensures the quality of the rubber tube processing, and avoids problems with improper installation later. In addition, it can also automatically move the rubber tube to the screen printing component. Through the rotation of the clamping positions and the translation of the screen printing component, the markings on the outer surface of the cylindrical rubber tube are automatically printed, meeting the needs of automatic processing and facilitating processing.

Detailed Implementation

[0033] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 11 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0034] Figure 1 This is a structural diagram of an embodiment of the automatic laser engraving and screen printing machine of the present invention. Figure 1 As shown, the automatic laser engraving and screen printing machine provided in this embodiment includes: a frame 1 and a turntable 2, an auxiliary drive assembly 3 and a screen printing assembly 4 disposed on the frame 1.

[0035] Figure 2 This is a preferred embodiment of the present invention, showing the turntable mounted on frame 1. Figure 1 and Figure 2As shown, a turntable 2 is rotatably mounted on one side of the frame 1. The turntable 2 rotates in a vertical plane, allowing it to move the workpiece to be processed vertically, adapting to the screen printing direction of the subsequent screen printing assembly 4. Simultaneously, several clamping positions 21 are arranged in a circular array on the outer edge of the turntable 2. These clamping positions 21 accommodate the installation of the rubber tubes to be processed, and drive the rubber tubes to be processed sequentially through the screen printing assembly 4, thus providing conditions for automated screen printing. Furthermore, each clamping position 21 includes a clamping fixing seat 211, a clamping rotating shaft 212, and a driven wheel 213. The clamping fixing seat 211 is mounted on the turntable 2, and the clamping rotating shaft 212 is rotatably mounted on the clamping fixing seat 211, with both ends extending axially out of the turntable 2. This satisfies the installation requirements on the turntable 2 through the clamping fixing seat 211, while also allowing the clamping rotating shaft 212 to rotate on the turntable 2, providing conditions for subsequently driving the rotation of the hose to be processed. Simultaneously, a driven wheel 213 is mounted on the end of the clamping rotating shaft 212 extending out of the turntable 2 and near the frame 1. The driven wheel 213 drives the clamping rotating shaft 212 to rotate, providing the driving conditions for the rotation of the clamping rotating shaft 212.

[0036] Figure 3 This is a structural diagram of an auxiliary drive component according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 3 As shown, the auxiliary drive assembly 3 includes an auxiliary lifting frame 31 and an auxiliary driver 32. The auxiliary lifting frame 31 is mounted on the frame 1 and moves vertically. The auxiliary driver 32 is mounted on the auxiliary lifting frame 31, so that the auxiliary lifting frame 31 can drive the auxiliary driver 32 to move vertically through its own lifting motion. During the lifting process of the auxiliary lifting frame 31, the auxiliary driver 32 can selectively contact the driven wheel 213. That is, a lifting wheel is installed on the drive shaft of the auxiliary driver 32. When the lifting wheel contacts the driven wheel 213, the driven wheel 213 can drive the clamping shaft 212 to rotate on the turntable 2, thereby meeting the rotation requirements of the rubber tube to be processed that is clamped on the clamping shaft 212, and ensuring that marking and printing can be performed on the outer surface of the cylindrical rubber tube.

[0037] Figure 4 This is a structural diagram of a screen printing assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 4As shown, the screen printing assembly 4 includes a translation frame 41, a screen printing frame 42, a squeegee 44, a lifting frame 43, and a squeegee 44. The translation frame 41 is horizontally positioned on the frame 1 and above the turntable 2, thus enabling the screen printing assembly 4 to be mounted on the frame 1. Furthermore, the translation frame 41 reciprocates along the tangent of the turntable 2. Simultaneously, the screen printing frame 42 is mounted on the translation frame 41 and positioned above several clamping positions 21, allowing the screen printing frame 42 to move tangentially along the turntable 2 in the horizontal plane, following the translation frame 41. It also allows the screen printing frame 42 to move tangentially along the clamping shaft 212, providing conditions for the screen printing frame 42 to adapt to the rotation of the tube to be processed through translation. Furthermore, the scraper 44 lifting frame 43 is set on the frame 1 and located above the screen printing frame 42. At the same time, the scraper 44 is installed on the scraper 44 lifting frame 43. The scraper 44 can be extended into the screen printing frame 42 through the scraper 44 lifting frame 43 and the height of the scraper 44 in the screen printing frame 42 can be controlled. When the screen printing frame 42 moves, by controlling the height of the scraper 44 in the screen printing frame 42, the ink in the screen printing frame 42 can be scraped flat and the ink can be scraped out of the screen printing mesh and printed on the surface of the rubber tube to be processed, thus meeting the requirements of automatic processing.

[0038] Figure 5 This is a structural diagram of a lifting adjustment assembly according to a preferred embodiment of the present invention. Figure 1 and 5 As shown, a lifting and adjusting assembly 5 is also provided between the frame 1 and the screen printing assembly 4. At this time, the lifting and adjusting assembly 5 includes an adjusting guide rail 51, an adjusting screw 52, ​​an adjusting slide plate 53, an adjusting screw block 54, and an adjusting driver 55. The adjusting guide rail 51 is vertically set on the frame 1, and the adjusting slide plate 53 is slidably set on the adjusting guide rail 51, so that the adjusting slide plate 53 can move up and down along the adjusting guide rail 51 in the vertical direction. The adjusting driver 55 is installed on the frame 1, and the adjusting screw 52 is arranged parallel to the adjusting guide rail 51 and is poweredly connected to the adjusting driver 55. The adjusting screw 52 is rotatably installed on the frame 1. At the same time, the adjusting screw block 54 is threaded onto the adjusting screw 52 and connected to the adjusting slide plate 53, so that when the adjusting driver 55 rotates, the adjusting driver 55 drives the adjusting screw 52 to rotate, thereby forcing the adjusting screw block 54 to move along the axial direction of the adjusting screw 52. That is, the adjusting screw block 54 drives the adjusting slide plate 53 to move on the adjusting guide rail 51, thereby realizing the adjustment of the height of the adjusting slide plate 53. Furthermore, the translation frame 41, the scraper 44, and the lifting frame 43 are all installed on the adjusting slide plate 53. That is, the height of the screen printing component 4 can be adjusted by adjusting the adjusting slide plate 53, thereby adjusting the distance between the screen printing component 4 and the clamping position 21 on the turntable 2. This ensures that the screen printing frame 42 can contact the tube to be processed during subsequent screen printing, meeting the screen printing requirements, and also meeting the printing and processing of tubes of different specifications and models. The structural design is more reasonable.

[0039] More specifically, a laser engraving machine 11 is also installed on the frame 1. The laser head of the laser engraving machine 11 faces the turntable 2, and as the turntable 2 rotates, the laser head corresponds sequentially to each clamping position 21. This allows the laser engraving machine 11 to engrave characters onto the rubber tubes clamped at the clamping positions 21. In other words, the rubber tubes can meet both screen printing requirements and marking requirements via the laser engraving machine 11, satisfying the processing of different styles of markings on the rubber tubes. This provides better adaptability and can accommodate more processing needs, thus providing conditions for the automatic processing and shaping of rubber tubes. It is worth noting that the laser engraving machine 11 can be purchased directly from the market; selecting a suitable specification and model that meets the laser engraving requirements is sufficient. Furthermore, the technology of existing laser engraving machines 11 is mature; therefore, its specific structure will not be described in detail here.

[0040] More specifically, a blower 12 is also installed on the frame 1. The air outlet of the blower 12 faces the turntable 2, and as the turntable 2 rotates, the air outlet corresponds sequentially to each clamping position 21. This means the blower 12 dries the screen-printed tubing on the clamping position 21, allowing the printed markings to dry quickly, improving processing efficiency and facilitating subsequent unloading, preventing damage to the markings after unloading. Furthermore, along the rotation direction of the turntable 2, the air outlet is located behind the screen-printing assembly 4, ensuring that the blower 12 dries only products that have not fully dried after screen printing, resulting in a more rational structural design.

[0041] Figure 6 This is a structural diagram of an end-drive assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 6 As shown, an end drive assembly 121 is also provided on the frame 1 at the position corresponding to the blower 12. The end drive assembly 121 includes an end telescopic frame 1211, an end driver 1212, and an end drive wheel 1213. The end telescopic frame 1211 is installed inside the frame 1 and moves telescopically along the axial direction of the turntable 2, allowing it to move away from or towards the turntable 2. Simultaneously, the end driver 1212 is installed on the end telescopic frame 1211, allowing it to follow the end telescopic frame 1211 as it moves closer to or further away from the turntable 2. Furthermore, the drive shaft of the end driver 1212... An end drive wheel 1213 is installed on the end. When the end telescopic frame 1211 extends or retracts, the end drive wheel 1213 selectively contacts the driven wheel body 213. That is, when the end driver 1212 approaches the turntable 2, the end drive wheel 1213 contacts the driven wheel body 213, thereby driving the driven wheel body 213 to rotate, causing the clamping shaft 212 to rotate, thereby driving the screen-printed rubber tube clamped on the clamping shaft 212 to rotate, so that the blower 12 can blow air evenly on the surface of the screen-printed rubber tube, ensuring the drying effect and making the structural design more reasonable.

[0042] Figure 7 This is a structural diagram of a feeding assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 7 As shown, a feeding assembly 6 is also provided on the frame 1. The feeding assembly 6 is located on one side of the turntable 2 and at the end of the clamping shaft 212 opposite to the driven wheel 213. This means the feeding assembly 6 can automatically feed the hose to be processed onto the clamping shaft 212 from the end opposite to the driven wheel 213. Furthermore, the feeding assembly 6 includes a conveyor belt 61, a feeding rack 62, and a pusher rack 63. The conveyor belt 61 is located beside the frame 1, with one end extending to the turntable 2. The feeding rack 62 is located at the end of the conveyor belt 61 extending to the turntable 2 and has a feeding trough 621, allowing the hose to be processed conveyed by the conveyor belt 61 to fall into the feeding trough 621. When the turntable 2 rotates, the feeding trough 621 sequentially connects with the clamping shaft 21 of each clamping position 21. The axial alignment of 2 ensures that the hose to be processed falling into the loading trough 621 is aligned with the clamping shaft 212. At the same time, the pusher 63 is located on the side of the loading rack 62 away from the turntable 2, and the pusher head of the pusher 63 selectively extends into the loading trough 621. When the pusher head extends into the loading trough 621, it can push the hose to be processed in the loading trough 621 toward the clamping shaft 212, so that the hose to be processed can be fitted over the clamping shaft 212, thus completing the automatic loading operation.

[0043] Figure 8 This is a structural diagram of the feeding assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 8 As shown, the frame 1 is also equipped with a feeding component 7. Along the rotation direction of the turntable 2, the feeding component 7 is located on the side of the turntable 2 and behind the screen printing component 4. This not only prevents the feeding component 7 from interfering with the rotation of the turntable 2, but also automatically removes the screen-printed tube from the clamping position 21, thus meeting the automatic feeding requirements. At this time, the unloading assembly 7 includes an unloading slide frame 71 and a gripper 72. The unloading slide frame 71 is installed on the frame 1 and moves back and forth along the axis of the turntable 2, so that the unloading slide frame 71 can move away from or towards the turntable 2 along the axis of the turntable 2. At the same time, the gripper 72 is installed on the unloading slide frame 71, so that the gripper 72 moves away from or towards the turntable 2 along the axis of the turntable 2 under the action of the unloading slide frame 71. Thus, when the gripper 72 clamps the rubber tube on the clamping position 21, the rubber tube can be removed from the clamping position 21 by moving the gripper 72 driven by the unloading slide frame 71, thus completing the automatic unloading operation.

[0044] More specifically, a flipping driver 73 is provided between the unloading slide frame 71 and the gripper 72. The flipping driver 73 is mounted on the unloading slide frame 71, and the gripper 72 is mounted on the flipping shaft of the flipping driver 73. This allows the flipping driver 73 to move with the unloading slide frame 71, and also allows the flipping slide frame to drive the gripper 72 to flip. Furthermore, the flipping shaft of the flipping driver 73 is arranged perpendicularly to the clamping shaft 212 of the clamping position 21. This allows the gripper 72 to further feed the processed tubing out after the gripper 72 removes the processed tubing from the clamping position 21, and then flips the gripper 72 via the flipping driver 73, thus better meeting the needs of automated processing.

[0045] Figure 9 This is a structural diagram of an auxiliary support frame according to a preferred embodiment of the present invention. Figure 1 and Figure 9 As shown, an auxiliary support frame 8 is also provided on the frame 1 and located at the center of the turntable 2. At this time, a through hole is opened in the center of the turntable 2. The auxiliary support frame 8 includes a support rod 81, an auxiliary telescopic device 82, and a pressure roller 83. One end of the support rod 81 is installed on the frame 1. The support rod 81 is arranged along the axial direction of the turntable 2 and one end of the support rod 81 is fixed to the frame 1. The other end of the support rod 81 extends out of the turntable 2 from the through hole. At the same time, the auxiliary telescopic device 82 is installed on the end of the support rod 81 that extends out of the turntable 2, so that the support rod 81 can serve as the mounting carrier for the auxiliary telescopic device 82. Furthermore, the auxiliary telescopic device 82 is located below the screen printing frame 42, and the auxiliary telescopic device 82 is arranged radially along the turntable 2 and is located on both sides of the clamping position 21 with the scraper 44. The pressure roller 83 is set on the telescopic shaft of the auxiliary telescopic device 82 and moves closer to or away from the clamping position 21. That is, the telescopic movement of the auxiliary telescopic device 82 allows the pressure roller 83 to move closer to or away from the clamping position 21. In other words, the pressure roller 83 presses against or releases the clamping position 21, so that when screen printing is required, the pressure roller 83 can press against the rubber tube to be processed, so that the rubber tube can be tightly attached to the screen printing frame 42, ensuring the quality of screen printing processing.

[0046] Figure 10 This is a structural diagram of a positioning component according to a preferred embodiment of the present invention. Figure 1 and Figure 10As shown, a positioning component 9 is also provided on the frame 1. At this time, along the rotation direction of the turntable 2, the positioning component 9 is located in front of the screen printing component 4. That is, the positioning component 9 pushes the tube to be processed, which is automatically fed by the feeding component 6, further towards the clamping shaft 212 on the clamping position 21, so that the tube to be processed can be clamped in place, thereby ensuring the accuracy of processing. Furthermore, the positioning component 9 includes a mounting block 91, a positioning driver 92, and a pressure block 93. One end of the mounting block 91 is mounted on the frame 1 and arranged radially along the turntable 2, thus enabling the positioning component 9 to be installed on the frame 1. The positioning driver 92 is mounted on the mounting block 91, and the pressure block 93 is mounted on the telescopic shaft of the positioning driver 92, moving towards or away from the clamping position 21 along the axial direction of the turntable 2. When the pressure block 93 moves towards the turntable 2 under the action of the positioning driver 92, it can press against the end of the hose to be processed on the clamping position 21, thereby pushing the hose to be processed to move and clamping it into place. This further ensures the accuracy of the markings on the processed hose and improves product quality. It is worth noting that the end of the mounting block 91 mounted on the frame 1 can be mounted on the support rod 81 of the auxiliary support frame 8, eliminating the need for a separate mounting structure and making the structural design more reasonable.

[0047] Figure 11 This is a structural diagram of a feeding adjustment assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 11As shown, a feeding adjustment component 64 is also provided between the feeding component 6 and the frame 1. At this time, the feeding adjustment component 64 is located below the feeding component 6, that is, the feeding adjustment component 64 serves as the mounting carrier for the feeding component 6. Meanwhile, the feeding adjustment component 64 includes a mounting plate 641, a sliding plate 642, a lifting plate 643, an adjusting rod 644, and a guide rod 645. The mounting plate 641 is arranged horizontally and one side is fixed to the frame 1. The sliding plate 642 is slidably mounted on the mounting plate 641 along the axial direction of the turntable 2, so that the sliding plate 642 can be adjusted by moving to adjust the distance between itself and the turntable 2 to adapt to the feeding requirements of hoses of different lengths to be processed. Meanwhile, a guide hole is vertically formed on the sliding plate 642, and a guide rod 645 passes through the guide hole. A lifting plate 643 is mounted on the upper end of the guide rod 645, and the lifting plate 643 is arranged parallel to the mounting plate 641 and the sliding plate 642. The guide rod 645 maintains the parallel relationship between the lifting plate 643 and the sliding plate 642, and the movement of the guide rod 645 within the guide hole accommodates the height adjustment requirements of the lifting plate 643. Furthermore, the feeding assembly 6 is mounted on the lifting plate 643. An adjusting rod 644, parallel to the guide rod 645, is also provided between the lifting plate 643 and the sliding plate 642. The upper end of the adjusting rod 644 is rotatably mounted on the bottom of the lifting plate 643, and the lower end is threadedly connected to the sliding plate 642. Rotating the adjusting rod 644 allows it to extend and retract on the lifting plate 643, thereby driving the lifting plate 643 to move up and down, thus adjusting the height of the lifting plate 643. The height of the feeding trough 621 in the material assembly 6 is adapted to the feeding requirements of rubber tubes of different diameters to be processed. This allows the rubber tubes to be processed in the feeding trough 621 to always be axially aligned with the clamping shaft 212 of each clamping position 21 by adjusting the positions of the sliding plate 642 and the lifting plate 643 after changing to different specifications of rubber tubes. This provides the conditions for the pusher frame 63 to put the rubber tubes to be processed in the feeding trough 621 onto the clamping shaft 212 on the clamping position 21.

[0048] More specifically, the mounting plate 641 has several strip-shaped sliding holes 6411 along the axial direction of the turntable 2, giving each sliding hole a certain length. These sliding holes 6411 are vertically aligned with the guide rod 645 and the adjusting rod 644, meaning each has a corresponding sliding hole 6411. Furthermore, the lower end of the guide rod 645 passes through the guide hole and extends into the corresponding sliding hole 6411. Similarly, the lower end of the adjusting rod 644 is threaded to the sliding plate 642, extends below the sliding plate 642, and extends into the corresponding sliding hole 6411. This design ensures that when the sliding plate 642 needs to move along the axial direction of the turntable 2 on the mounting plate 641, the sliding holes 6411 provide clearance for the guide rod 645 and the adjusting rod 644, guaranteeing the normal movement of the sliding plate 642 and resulting in a more rational structural design.

[0049] In a preferred embodiment, the auxiliary driver 32, the adjustment driver 55, and the end driver 1212 are electric motors, the flipping driver 73 is a rotary cylinder, and the auxiliary telescopic device 82 and the positioning driver 92 are telescopic cylinders. As long as the usage requirements are met, the technology is mature and more convenient to use.

[0050] The automatic laser engraving and screen printing machine provided in this embodiment includes a frame 1, an auxiliary drive assembly 3, and a screen printing assembly 4. A turntable 2 rotating in a vertical plane is provided on the frame 1, and several clamping positions 21 are rotatably mounted on the turntable 2. The auxiliary drive assembly 3 selectively drives the clamping positions 21 to rotate, and the screen printing assembly 4 is positioned above the turntable 2. The clamping positions 21 clamp the rubber tube to be processed, and the auxiliary drive assembly 3 drives the rubber tube to rotate when it contacts the clamping positions 21. Simultaneously, the screen printing assembly 4 slides on the frame 1. The sliding of the screen printing assembly 4 and the rotation of the clamping positions 21 enable the printing of markings on the surface of the rubber tube to be processed. This ensures the uniformity and accuracy of the processing position and standards for the rubber tube markings, guarantees processing quality, avoids problems with improper installation later, and also achieves automatic processing, improving processing efficiency and better meeting processing needs.

Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
