[0035] During the scribing process of the pipe, the pipe needs to be supported. Therefore, a bracket 26 is fixedly connected inside the processing bin 1. The length of the bracket 26 is provided with multiple support components that cooperate with the pipe. The support components include: a positioning block 27 fixedly connected to the bracket 26. The positioning block 27 is hinged with a support plate 28. The support plate 28 is rotatably connected with a roller that contacts the pipe. One end of a tension spring 29 is fixedly connected to the support plate 28, and the other end of the tension spring 29 is fixedly connected to the support plate 28. The positioning block 27 is provided with a limiting portion, and the support plate 28 is fixedly connected with a limiting rod that cooperates with the limiting portion. Since the pipe is relatively long, it is inevitable that the pipe will be deformed due to the action of gravity during the pad printing process. By using multiple support components to support the pipe, the accuracy of the scribing size is improved, and the overall deformation amount of the pipe is reduced. Under the action of the tension spring 29, the support plate 28 is driven to rotate around the hinge end until the limiting rod contacts the limiting portion, driving the pipe to be supported.

[0036] Inside the processing bin 1, there is also a moving seat 2 that moves along the length direction of the pipe. Inside the processing bin 1, there is a slide rail that cooperates with the moving seat 2. The moving seat 2 is fixedly connected with a displacement motor 30.

A driving gear is arranged on the output shaft of the displacement motor 30. By the cooperation of the driving gear and the rack 31, the moving seat 2 is driven to move along the length direction of the slide rail (the length direction of the slide rail is the axial direction of the pipe).

[0037] The moving seat 2 is fixedly connected with a pad printing component for marking the outer surface of the pipe. The outer surface of the pipe is printed by the pad printing component.

[0038] The pad printing component includes: a horizontal module 4 arranged on the moving seat 2 through a connecting frame 3. A vertical module 5 is movably arranged on the horizontal module 4. A lifting frame is movably arranged on the vertical module 5. The lifting frame is provided with a marking component that cooperates with the pipe. The moving seat 2 is fixedly connected with a seasoning placement component that cooperates with the marking component. By driving the marking component to move horizontally through the horizontal module 4, mainly driving the marking component to move from the seasoning placement component to the pipe or the marking component to move from the pipe to the seasoning placement component.

[0039] The vertical module 5 mainly drives the marking component to perform longitudinal displacement, so as to realize the contact between the marking component and the pipe or the seasoning placement component.

[0040] The marking component includes: a moving motor 7 fixedly arranged on the lifting frame. The output shaft of the moving motor 7 is fitted with two marking blocks 8. The moving motor 7 drives the two marking blocks 8 to move towards each other or in opposite directions. By adjusting the distance between the two marking blocks 8 through the moving motor 7, the positions of the two marking blocks 8 corresponding to the pipe are ensured, and the position adjustment of the marking is realized.

[0041] The seasoning placement component includes: a support frame 9 fixed on the moving base 2. The support frame 9 is connected with a displacement plate 10 through an adjustment component. The displacement plate 10 is fixedly connected with a driving cylinder 11. The telescopic rod of the driving cylinder 11 is fixedly connected with a printing plate 12. There is an oil cup 13 directly above the printing plate 12. The oil cup 13 is fixedly connected with the displacement plate 10 through a positioning frame 14. The printing plate 12 has multiple workstations, and each workstation is provided with a seasoning groove 1201 that cooperates with the oil cup 13. The driving cylinder 11 drives the seasoning groove 1201 of the printing plate 12 to cooperate with the marking block 8.

[0042] When the oil cup 13 contacts one of the workstations, it will drive the seasoning into the seasoning groove 1201 (using the existing oil cup 13 of the pad printer to drive the seasoning into the seasoning groove 1201).

[0043] The multiple workstations mainly play a supporting role for the oil cup 13, reducing the state where the oil cup 13 is suspended.

[0044] The adjustment component includes: a slider 15 fixedly arranged at the bottom of the moving plate. The bottom of the slider 15 is fixedly connected with a nut. The support frame 9 is rotatably connected with a lead screw that cooperates with the nut. The lead screw extends outside the support frame 9 and is connected with a hand wheel 16. The hand wheel 16 mainly drives the cooperation of the lead screw and the nut to realize the lateral displacement of the slider 15, adjust the position of the seasoning groove 1201 and the marking block 8, and improve the processing accuracy.

[0045] The pad printing component further includes: positioning plates 17 fixedly arranged on both sides of the displacement plate 10. Both positioning plates 17 are rotatably connected with rotating brackets 18. The rotating brackets 18 are each provided with a roller 19 through a plurality of positioning columns. A tape is wound around each roller 19, and the adhesive surface of the tape faces the two marking blocks 8. One of the positioning plates 17 is fixedly connected with a driving motor 20. The output shaft of the driving motor 20 is fixedly connected with one of the rotating brackets 18. The driving motor 20 drives the tape to wind from one roller 19 to the other roller 19. The tape mainly cleans the dust and impurities on the marking block 8. Since the marking block 8 drives the seasoning to contact the pipe, there may be impurities on the surface of the pipe. After the marking block 8 finishes marking, it will drive the impurities to move towards the seasoning groove 1201. Therefore, the adhesive surface of the tape is used to clean the impurities on the marking block 8, reducing the adsorption of impurities on the marking block 8 and resulting in marking defects when contacting the pipe.

[0046] When the marking block 8 is marking, it is necessary to support the pipe. Therefore, the moving base 2 is fixedly connected with a connecting plate. The connecting plate is fixedly connected with a support cylinder 32. The telescopic rod of the support cylinder 32 is fixedly connected with a support plate. The support plate is rotatably connected with a plurality of rollers that cooperate with the pipe. The support plate drives the rollers to contact the pipe, playing a supporting role for the pipe and improving the marking effect.

[0047] The moving seat 2 is also fixedly connected with a cutting plate. The cutting plate is fixedly connected with a cutting cylinder 33. The cutting plate is provided with a cutting groove adapted to the pipe. The telescopic rod of the cutting cylinder is fixedly connected with a cutting knife adapted to the cutting groove. After the pipe is marked, the cutting cylinder drives the cutting knife to cooperate with the cutting groove to realize the cutting of the pipe.

[0048] During operation, the pipe is driven to be placed on a plurality of supporting components, and then the two ends of the pipe are clamped by the clamping components. After the pipe is clamped, a driving gear is arranged on the output shaft of the displacement motor 30, and the driving gear cooperates with the rack 31, so as to drive the moving seat 2 to move along the length direction of the slide rail (the length direction of the slide rail is also the axial direction of the pipe). When the moving seat 2 moves to the position where the pad printing component needs to mark.

[0049] The longitudinal module 5 mainly drives the marking component to move longitudinally, so as to realize the contact between the marking component and the seasoning placing component, realize the cooperation between the marking block 8 and the seasoning groove 1201, and realize that the lower surface of the marking block 8 adsorbs the seasoning. The longitudinal module 5 drives the marking block 8 to move upward, and then the transverse module 4 drives the marking block 8 to move horizontally until it moves to directly above the pipe, and the longitudinal module 5 drives the marking block 8 to move downward to contact the outer surface of the pipe.

[0050] At this time, the rotating motor 23 drives the pipe to rotate. While the pipe is rotating, the transverse module 4 also moves, driving the seasoning adsorbed by the marking block 8 to be evenly marked on the outer surface of the pipe. The distance between the two marking blocks 8 is adjusted according to the requirements, so as to adjust the distance between the same group of marks.

[0051] When the marking block 8 finishes working, the transverse module 4 and the longitudinal module 5 work to drive the marking block 8 to contact the adhesive surface of the tape (this can be set randomly and does not necessarily contact the tape every time after marking), driving the impurities and the remaining paint on the marking block 8 to be cleaned, so as to improve the overall cleaning effect of the marking block 8.

[0052] In this way, the outer surface of the pipe is marked repeatedly (according to the set requirements, the output shaft of the displacement motor 30 is controlled to rotate, so as to control the moving distance of the moving seat 2 to realize the specific marking position on the pipe).

[0053] After the marking is completed, the cutting cylinder drives the cutting knife to cooperate with the cutting groove to realize the cutting of the pipe.

[0054] The disclosed embodiments of the present utility model are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model according to the above embodiments and make different extensions and changes, but as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
