Description

Technical Field

[0001] The present invention relates to the technical field of ABS plate production marking, in particular to an ABS plate continuous marking device. Background Art

[0002] As we all know, ABS sheet is an emerging material in the sheet industry. Its full name is acrylonitrile / butadiene / styrene copolymer sheet. It is a polymer with large production volume and wide application. Continuous marking of ABS sheet refers to the process of continuously and automatically marking various types of information on the surface of the sheet through specific equipment and technology during the continuous production or processing of ABS sheet.

[0003] In the continuous production of ABS sheets, the marking process is a key link in achieving product traceability, specification identification, and personalized customization. However, the existing continuous marking technology for ABS sheets has the following significant defects in practical applications: the existing technology is difficult to simultaneously meet the requirements of different thicknesses. When marking sheets with varying thicknesses, traditional devices require manual adjustment of the marking head height. The adjustment accuracy depends on operating experience, and the adjustment process is time-consuming, seriously affecting production efficiency. In addition, for curved ABS sheets, the fixed-angle marking head cannot adapt to the curvature of the curved surface, causing the angle between the marking surface and the nozzle to deviate from the optimal angle, affecting the marking quality. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an ABS sheet continuous marking device, which has an integrated marking system of dynamic centering, adaptive marking and precise ink control through the coordinated design of a conveying structure, a centering holding structure and a marking structure.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a continuous marking device for ABS sheet materials, comprising a conveying structure, a central retaining structure bolted to the interior of the conveying structure, a bracket bolted to the top of the conveying structure, and a marking structure disposed within the bracket, the marking structure comprising a marking mechanism located within the bracket, an adaption mechanism bolted to the front and rear sides of the bracket, and the adaption mechanism being slidably connected to the marking mechanism on a side adjacent to the marking mechanism; The marking mechanism includes two arc-shaped guide rails, and the top and bottom between the two arc-shaped guide rails on the front and rear sides are both notched. The opposite sides of the arc-shaped guide rails are bolted with connecting frames, and the top between the two connecting frames is bolted with an ink replenishing assembly. The ink replenishing assembly is slidingly connected to the adaptation mechanism on the side close to the adaptation mechanism, and a marking head is rotatably connected between the opposite sides of the two connecting frames, and one end of the marking head is between the two arc-shaped guide rails. The marking head is used in conjunction with the ink replenishing assembly.

[0006] With the above technical solution, by providing a marking mechanism, when the sheet is conveyed on the conveying structure, the adapting mechanism will first contact the sheet and automatically adjust the distance between the marking mechanism and the sheet according to the thickness of the sheet, thereby enabling the marking mechanism to adapt to sheets of different thicknesses, making the marking mechanism adaptable and flexible, and eliminating the need for manual adjustment. When marking the sheet, an external drive device drives the marking head to rotate. When the marking head rotates along the inner wall of the curved guide rail, the marking head is constrained by the curved guide rail and is in a retracted state. When the marking head is in the notch-shaped portion at the bottom, the curved guide rail loses its constraint on the marking head. Therefore, the marking head will reset under the elastic action of its own elasticity and generate a certain contact force with the sheet. Therefore, the marking head will print the marking information on the sheet, thereby marking the sheet. As the marking head continues to rotate, the marking head will contact the end of the curved guide rail again, be constrained again, and retract. When the marking head moves to the ink replenishing assembly, the above steps will be repeated and the marking head will contact the ink replenishing assembly, and the ink replenishing assembly will replenish the ink in the marking head. Through the above steps, the marking head achieves connection marking of the sheet.

[0007] The present invention is further configured as follows: a guide rod is bolted to the top of the ink replenishing assembly, and a connecting plate is slidably sleeved on the surface of the guide rod; an adjustment frame is bolted to the top of the connecting plate, and an adjustment screw is passed through the internal thread of the adjustment frame; both ends of the adjustment screw are rotatably connected to the inner wall of the bracket.

[0008] By adopting the above technical solution, the adjustment screw is driven to rotate by an external driving device, which can drive the adjustment frame to move left and right along the adjustment screw, and then drive the ink replenishing component to adjust the lateral position to adapt to the needs of different marking positions. Through the setting of the guide rod and the connecting plate, the moving trajectory of the marking mechanism can be limited when the adaptation mechanism adjusts the height of the marking mechanism.

[0009] The present invention is further configured as follows: the ink replenishing assembly includes a storage box, the storage box is bolted to the bottom of the guide rod, the bottom of the storage box is connected to a quantity control part, and the bottom of the quantity control part is connected to a shell, an adsorption sponge is provided inside the shell, the top and bottom of the adsorption sponge are respectively filled with a fixed plate and a movable plate, a movable rod is provided on the top of the movable plate, the top of the movable rod passes through the fixed plate and is connected to the quantity control part, an elastic sleeve is sleeved on the surface of the guide rod, and the elastic sleeve is connected to the fixed plate and the movable plate on one side respectively.

[0010] By adopting the above technical solution, an ink replenishing component is set up. When the marking head contacts the adsorption sponge, the ink stored inside it will be automatically replenished to the marking head. When the marking head contacts the adsorption sponge, it will push the movable plate and the movable rod to move, and the elastic sleeve will shrink. Under the push of the movable rod, the control part will automatically open, so that the ink in the storage box will be replenished to the adsorption sponge in small amounts, and excessive ink discharge will be avoided. Therefore, the ink is evenly dispersed through the adsorption sponge, avoiding the flow caused by local excess ink, improving the flatness of the marking surface, and keeping the amount of ink adsorbed by the adsorption sponge within a certain range, which is convenient for continuous marking of the marking head.

[0011] The present invention is further configured as follows: the quantity control part includes a connecting tube, which is connected between the storage box and the shell, and a fixing ring is provided inside the connecting tube. The interior of the fixing ring is hollow, and the interior of the fixing ring is in close contact with a blocking sphere, and a connecting rod is welded to the bottom of the blocking sphere, and the bottom of the connecting rod is connected to the movable rod, and a first return spring is provided at the bottom of the fixing ring, and the bottom of the first return spring is connected to the surface of the movable rod.

[0012] By adopting the above technical solution, by setting a control part, when the movable plate and the movable rod move upward, the connecting rod will be pushed to move synchronously, and since the upper end of the movable rod is provided with a hollow plate-like structure connected to the first return spring, the upward movement of the movable rod will compress the first return spring through the hollow plate-like structure, so that the connecting rod pushes the blocking ball out from the inside of the fixed ring, which can release the blockage of the fixed ring and allow the ink in the storage box to enter the adsorption sponge, thereby realizing the supply of ink to the adsorption sponge. When the movable plate and the movable rod move downward, the elasticity of the first return spring can be used to make the blocking ball re-seal the fixed ring, thereby completing an ink supply operation.

[0013] The present invention is further configured as follows: the marking head includes a rotating shaft, a shaft sleeve is sleeved on the surface of the rotating shaft, and a fixing rod is welded to the rear side of the shaft sleeve, a sliding sleeve is slidably sleeved on the surface of the fixing rod, and a second return spring is provided on the inner wall of the sliding sleeve, the other end of the second return spring is connected to the fixed rod, a ball hinge is bolted to the rear side of the sliding sleeve, and a marking plate is bolted to the rear side of the ball hinge, a push block is sleeved on the surface of the ball hinge, and the push block is in sliding contact with the side close to the arc guide rail.

[0014] The above technical solution is adopted, by setting a marking head, and driving the rotating shaft to rotate between the two connecting frames through an external driving device, and driving the fixed rod and the sliding sleeve to rotate through the shaft sleeve. When the pushing block rotates along the inner wall of the arc guide rail, the pushing block is constrained by the arc guide rail to drive the sliding sleeve to move on the fixed rod and cause the second return spring to be in a contracted state. When the pushing block is in the bottom notch-shaped part, the arc guide rail loses its constraint on the pushing block, so it will be reset under the elastic action of the second return spring and generate a certain contact force with the plate. Therefore, the marking plate will print the marking information on the plate, and through the setting of the ball joint, the marking plate can adapt to a certain curved surface of the plate and has good flexibility, thereby realizing marking of the plate. As the rotating shaft continues to rotate, the pushing block will contact the end of the arc guide rail again and be constrained and contracted. When the marking plate moves to the ink replenishing component, the above steps will be repeated and contact the ink replenishing component, and the ink replenishing component will replenish the ink on the marking plate. Through the above steps, the marking head realizes the connection marking of the plate.

[0015] The present invention is further configured as follows: the adaptation mechanism includes two support plates, the support plate is bolted to the bracket on one side close to the support plate, a moving rod passes through the interior of the support plate, the bottom of the moving rod is bolted to a mounting bracket, the interior of the mounting bracket is rotatably connected to an adaptation wheel, and a lifting plate is welded to the surface of the adaptation wheel in a ring shape, a U-shaped lifting plate is sleeved between the surfaces of the two moving rods, a guide plate is bolted between the side of the lifting plate close to the bracket, and the guide plate is slidably connected to the storage box, a third return spring is sleeved on the surface of the moving rod, and the third return spring is connected to the lifting plate and the support plate on one side close to the two.

[0016] By adopting the above technical solution and setting up an adaptive mechanism, when the plate is conveyed on the conveying structure, its end in the conveying direction will contact the bottom lifting plate and push the adaptive wheel to rotate, so that the lifting plate on the front side will contact the surface of the plate, thereby automatically lifting the lifting plate and the mounting frame, and synchronously driving the moving rod and the lifting plate to move. The movement of the lifting plate will drive the marking mechanism to rise through the guide plate, so that the marking mechanism can adapt to plates of different thicknesses, making the marking mechanism adaptable and flexible, and no manual adjustment is required.

[0017] The present invention is further configured as follows: limiting protrusions are provided on the front and rear sides of the storage box, and a limiting groove for use with the limiting protrusion is provided on one side of the guide plate close to the limiting protrusion, and the limiting protrusion is slidably arranged inside the limiting groove.

[0018] By adopting the above technical solution, by setting the limiting protrusion and the limiting groove, the marking mechanism can be connected to the guide plate without affecting the adjustment of the marking position, thereby facilitating the guide plate to drive the marking mechanism to rise or fall.

[0019] The present invention is further configured as follows: inclined portions are provided at both ends of the inner side of the arc-shaped guide rail, an arc-shaped portion with a smooth curved surface is provided on one side of the push block close to the arc-shaped guide rail, and the arc-shaped portion is used in conjunction with the inclined portion.

[0020] By adopting the above technical solution, the inclined portions at both ends of the inner side of the arc-shaped guide rail are inclined along the extension direction of the arc-shaped guide rail. Specifically, when transitioning from the ends of the arc-shaped guide rail to the middle notch, the inclined portions are inclined in the direction away from the marking head. The inclination reference is the central axis of the arc-shaped guide rail, that is, the tangent direction of the inclined portion and the tangent direction of the middle part of the arc-shaped guide rail form an angle of 15 degrees to 30 degrees, ensuring that the push block can be gradually subjected to force when it contacts the inclined portion, and because a smooth arc portion is provided on the side of the push block close to the arc-shaped guide rail, the curvature radius of the arc portion is the same as the curvature radius of the arc-shaped guide rail. Correspondingly, when the pushing block rotates to the end of the arc-shaped guide rail, the arc-shaped portion first contacts the inclined portion. The inclination angle of the inclined portion causes the pushing block to be subjected to a radially inward force along the arc-shaped guide rail, driving the sliding sleeve to compress the second return spring, thereby achieving a smooth contraction of the marking head; when the pushing block leaves the inclined portion and enters the middle notch, the force component gradually disappears, and the second return spring resets to allow the marking head to extend smoothly. This design converts the rotational motion of the pushing block into a linear motion of axial contraction / extension through the progressive contact between the inclined surface and the arc-shaped surface, thereby avoiding rigid collision and achieving a smooth transition.

[0021] The present invention is further configured as follows: the central retaining structure includes two shafts, the shafts are rotatably connected to the bottom of the conveying structure, screws are welded on both sides of the shaft, the surface of the screws is threadedly connected to a movable plate, and the opposite sides of the two movable plates on both sides are bolted with connecting shafts, the side of the connecting shaft away from the movable plate is bolted with a fixing frame, the front and rear sides of the fixing frame are rotatably provided with retaining wheels, and the surface threads of the two screws on both sides are arranged in opposite directions.

[0022] By adopting the above technical solution and setting up a centering holding structure, the screw can be driven to rotate by the shaft, and the screw and the thread of the movable plate can cooperate to make the movable plates on both sides move relative to or oppositely. The distance between the holding wheels on both sides can be adjusted to achieve automatic centering of the plate, thereby adapting to the automatic positioning of plates of different widths and avoiding the problem of marking position deviation caused by plate offset.

[0023] The present invention is further configured as follows: a driving motor is bolted to the bottom of the conveying structure, and a driving shaft is bolted to the output end of the driving motor; synchronous wheels are sleeved on the surfaces of the driving shaft and the shaft, and a synchronous belt is wound between the insides of two adjacent synchronous wheels.

[0024] By adopting the above technical solution, a drive shaft, a synchronous wheel and a synchronous belt are set up, and the drive shaft is driven to rotate by a drive motor. Under the action of the synchronous wheel and the synchronous belt, the effect of synchronous rotation of the two shafts is achieved, so that the retaining wheels on the front and rear sides can be displaced synchronously, ensuring the effect of centering the plate.

[0025] Compared with the prior art, the present invention provides an ABS sheet continuous marking device, which has the following beneficial effects: The ABS sheet continuous marking device has a centering holding structure that automatically centers the sheet through a screw drive. Combined with the setting of the ball joint in the marking structure, the marking head can adapt to changes in moving thickness and curved surfaces, solving the problem of manual adjustment required for traditional devices. The symmetrical screw drive in the centering holding structure enables the holding wheels on both sides to move synchronously toward the center, which can adapt to the automatic positioning of sheets of different widths and solve the problem of marking position deviation caused by sheet offset in traditional transportation. The adaptation mechanism in the marking structure can automatically adapt to sheets of different thicknesses, and the position of the marking mechanism will be synchronously adjusted during its adaptation process, so that the marking structure has adaptability and flexibility. In addition, the ink replenishing component can automatically replenish the marking head with an appropriate amount of ink after each marking is completed, which can avoid excess or insufficient ink and improve the consistency of marking quality.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: See also Figure 1-7 A continuous marking device for ABS sheets includes a conveying structure 1, a bracket 3 is bolted to the top of the conveying structure 1, and a marking structure 4 is provided inside the bracket 3. The marking structure 4 includes a marking mechanism 5, and the marking mechanism 5 is inside the bracket 3. The front and rear sides of the bracket 3 are both bolted to an adaptation mechanism 6, and the adaptation mechanism 6 is slidably connected to the marking mechanism 5 on the side close to the adaptation mechanism 6; Please refer to Figure 3The marking mechanism 5 includes two arcuate guide rails 51, and the top and bottom between the two arcuate guide rails 51 on the front and rear sides are notched. Connecting frames 52 are bolted to the opposite sides of the arcuate guide rails 51, and an ink replenishing assembly 53 is bolted to the top between the two connecting frames 52. The ink replenishing assembly 53 is slidably connected to the side close to the adapting mechanism 6, and a marking head 54 is rotatably connected between the opposite sides of the two connecting frames 52, and one end of the marking head 54 is between the two arcuate guide rails 51. The marking head 54 is used in conjunction with the ink replenishing assembly 53. By setting the marking mechanism 5, when the plate is conveyed on the conveying structure 1, the adapting mechanism 6 will first contact the plate and automatically adjust the distance between the marking mechanism 5 and its plate according to the thickness of the plate, so that the marking mechanism 5 can adapt to plates of different thicknesses, so that the marking mechanism 5 has adaptability and flexibility, and does not require manual adjustment, and is convenient for marking the plate. During timing, the external driving device drives the marking head 54 to rotate. When the marking head 54 rotates along the inner wall of the arc guide rail 51, the marking head 54 is constrained by the arc guide rail 51 and is in a retracted state. When the marking head 54 is in the bottom notch-shaped part, the arc guide rail 51 loses its constraint on the marking head 54. Therefore, under the elastic action of the marking head 54 itself, it will reset and generate a certain contact force with the plate. Therefore, the marking head 54 will print the marking information on the plate to achieve marking of the plate. As the marking head 54 continues to rotate, the marking head 54 will contact the end of the arc guide rail 51 again and be constrained and retracted. When the marking head 54 moves to the ink replenishing component 53, it will repeat the above steps and contact the ink replenishing component 53, and the ink replenishing component 53 will replenish the ink for the marking head 54. Through the above steps, the marking head 54 achieves connection marking of the plate.

[0030] Among them, the top of the ink replenishing component 53 is bolted with a guide rod 7, and the surface of the guide rod 7 is slidably sleeved with a connecting plate 8, the top of the connecting plate 8 is bolted with an adjustment frame 9, and the internal thread of the adjustment frame 9 is penetrated by an adjustment screw 10, and both ends of the adjustment screw 10 are rotatably connected to the inner wall of the bracket 3. The adjustment screw 10 is driven to rotate by an external driving device, which can drive the adjustment frame 9 to move left and right along the adjustment screw 10, and then drive the ink replenishing component 53 to adjust its lateral position to meet the needs of different marking positions. Through the setting of the guide rod 7 and the connecting plate 8, the moving trajectory of the marking mechanism 5 can be limited when the adaptation mechanism 6 adjusts the height of the marking mechanism 5.

[0031] Among them, please refer to Figure 5 and Figure 6The ink replenishing assembly 53 includes a storage box 531, which is bolted to the bottom of the guide rod 7. The bottom of the storage box 531 is connected to the control piece 532, and the bottom of the control piece 532 is connected to the shell 533. An adsorption sponge 534 is provided inside the shell 533. The top and bottom of the adsorption sponge 534 are respectively filled with a fixed plate 535 and a movable plate 536. A movable rod 537 is provided on the top of the movable plate 536. The top of the movable rod 537 passes through the fixed plate 535 and is connected to the control piece 532. An elastic sleeve 538 is sleeved on the surface of the guide rod 7, and the elastic sleeve 538 is connected to the fixed plate 535 and the movable plate 536 on one side. By setting the ink replenishing assembly Part 53, when the marking head 54 contacts the adsorption sponge 534, the ink stored inside it will be automatically replenished to the marking head 54, and when the marking head 54 contacts the adsorption sponge 534, it will push the movable plate 536 and the movable rod 537 to move upward, and the elastic sleeve 538 will shrink. Under the push of the movable rod 537, the control part 532 will automatically open, so that the ink in the storage box 531 will be replenished to the adsorption sponge 534 in small quantities, and excessive ink discharge will be avoided. Therefore, the ink is evenly dispersed through the adsorption sponge 534, avoiding the flow caused by local excess ink, improving the flatness of the marking surface, and keeping the amount of ink adsorbed by the adsorption sponge 534 within a certain range, which is convenient for continuous marking by the marking head 54.

[0032] Among them, the control part 532 includes a connecting tube 532a, which is connected between the storage box 531 and the shell 533. A fixing ring 532b is provided inside the connecting tube 532a. The interior of the fixing ring 532b is hollow, and the interior of the fixing ring 532b is in close contact with a blocking ball 532c. A connecting rod 532d is welded to the bottom of the blocking ball 532c, and the bottom of the connecting rod 532d is connected to the movable rod 537. A first return spring 532e is provided at the bottom of the fixing ring 532b, and the bottom of the first return spring 532e is connected to the surface of the movable rod 537. By setting the control part 532, when the movable plate 536 and the movable rod 537 move up, they will synchronously push the connecting rod 532d. The rod 532d moves, and since the upper end of the movable rod 537 is provided with a hollow plate structure connected to the first return spring 532e, the upward movement of the movable rod 537 will compress the first return spring 532e through the hollow plate structure, so that the connecting rod 532d pushes the blocking ball 532c to move out from the inside of the fixed ring 532b, which can release the blockage of the fixed ring 532b and allow the ink in the storage box 531 to enter the adsorption sponge 534, thereby realizing the supply of ink to the adsorption sponge 534. When the movable plate 536 and the movable rod 537 move downward, the elasticity of the first return spring 532e can be used to make the blocking ball 532c re-seal the fixed ring 532b, thereby completing an ink supply operation.

[0033] Among them, please refer to Figure 4The marking head 54 includes a rotating shaft 541, a shaft sleeve 542 is sleeved on the surface of the rotating shaft 541, and a fixing rod 543 is welded on the rear side of the shaft sleeve 542, a sliding sleeve 544 is slidably sleeved on the surface of the fixing rod 543, and a second return spring 545 is provided on the inner wall of the sliding sleeve 544, the other end of the second return spring 545 is connected to the fixing rod 543, a ball hinge 546 is bolted to the rear side of the sliding sleeve 544, and a marking plate 547 is bolted to the rear side of the ball hinge 546, The surface of the hinge 546 is sleeved with a push block 548, and the push block 548 is in sliding contact with the side of the arc guide rail 51. By setting the marking head 54, the external driving device drives the rotating shaft 541 to rotate between the two connecting frames 52, and drives the fixed rod 543 and the sliding sleeve 544 to rotate through the shaft sleeve 542. When the push block 548 rotates along the inner wall of the arc guide rail 51, the push block 548 is constrained by the arc guide rail 51 and drives the sliding sleeve 544 to rotate on the fixed rod 543 moves up and makes the second return spring 545 contracted. When the pushing block 548 is in the notch-shaped part at the bottom, the arc guide rail 51 loses its constraint on the pushing block 548. Therefore, it will be reset under the elastic action of the second return spring 545 and generate a certain contact force with the plate. Therefore, the marking plate 547 will print the marking information on the plate, and through the setting of the ball hinge 546, the marking plate 547 can adapt to the plate with a certain curved surface and has good flexibility, thereby realizing the marking of the plate. As the rotating shaft 541 continues to rotate, the pushing block 548 will contact the end of the arc guide rail 51 again and be constrained and contracted. When the marking plate 547 moves to the ink replenishing component 53, it will repeat the above steps and contact the ink replenishing component 53, and the ink replenishing component 53 will replenish the ink to the marking plate 547. Through the above steps, the marking head 54 realizes the connection marking of the plate.

[0034] Among them, please refer to Figure 7The adaptation mechanism 6 includes two support plates 61, and the support plate 61 is bolted to the side of the bracket 3. A moving rod 62 is passed through the interior of the support plate 61, and a mounting bracket 63 is bolted to the bottom of the moving rod 62. The interior of the mounting bracket 63 is rotatably connected to an adaptation wheel 64, and a lifting plate 65 is welded to the surface of the adaptation wheel 64 in a ring shape. A U-shaped lifting plate 66 is sleeved between the surfaces of the two moving rods 62, and a guide plate 67 is bolted between the sides of the lifting plate 66 close to the bracket 3, and the guide plate 67 is slidably connected to the storage box 531. A third return spring 68 is sleeved on the surface of the moving rod 62, and the third return spring 68 is close to the top One side of the lifting plate 66 and the support plate 61 are respectively connected to the two. By setting up the adaptation mechanism 6, when the plate is conveyed on the conveying structure 1, its end in the conveying direction will contact the bottom lifting plate 65 and push the adaptation wheel 64 to rotate, so that the lifting plate 65 on the front side will contact the surface of the plate, thereby automatically lifting the lifting plate 65 and the mounting frame 63, and synchronously driving the moving rod 62 and the lifting plate 66 to move. The movement of the lifting plate 66 will drive the marking mechanism 5 to rise through the guide plate 67, so that the marking mechanism 5 can adapt to plates of different thicknesses, so that the marking mechanism 5 has adaptive flexibility and does not require manual adjustment.

[0035] Among them, the front and rear sides of the storage box 531 are both provided with limiting protrusions, and the side of the guide plate 67 close to the limiting protrusion is provided with a limiting groove for use therewith, and the limiting protrusion is slidably set inside the limiting groove. By setting the limiting protrusion and the limiting groove, the connection with the guide plate 67 can be achieved without affecting the adjustment of the marking position of the marking mechanism 5, thereby facilitating the guide plate 67 to drive the marking mechanism 5 to rise or fall.

[0036] Among them, inclined portions 14 are provided at both ends of the inner side of the arc guide rail 51, and an arc portion 15 with a smooth curved surface is provided on the side of the pushing block 548 close to the arc guide rail 51, and the arc portion 15 is used in conjunction with the inclined portion 14. The inclined portions 14 at both ends of the inner side of the arc guide rail 51 are inclined along the extension direction of the arc guide rail 51. Specifically, when transitioning from the ends of both ends of the arc guide rail 51 to the middle notch, the inclined portion 14 is inclined in the direction away from the marking head 54, and its inclination reference is the central axis of the arc guide rail, that is, the tangential direction of the inclined portion 14 and the tangential direction of the middle part of the arc guide rail 15 form an angle of 15 degrees to 30 degrees, ensuring that the pushing block 548 can be gradually subjected to force when contacting the inclined portion 14, and because the pushing block 548 is provided with a The smooth arc-shaped portion 15 has a curvature radius that matches the curvature radius of the arc-shaped guide rail 51. When the push block 548 rotates to the end of the arc-shaped guide rail 51, the arc-shaped portion 15 first contacts the inclined portion 14. The inclination angle of the inclined portion 14 causes the push block 548 to be subjected to a radially inward component of force along the arc-shaped guide rail 51, driving the sliding sleeve 544 to compress the second return spring 545, thereby achieving a smooth contraction of the marking head 54; when the push block 548 leaves the inclined portion 14 and enters the middle notch, the component of force gradually disappears, and the second return spring 545 is reset to allow the marking head 54 to extend smoothly. This design converts the rotational motion of the push block 548 into a linear motion of axial contraction / extension through the progressive contact between the inclined surface and the arc-shaped surface, thereby avoiding rigid collision and achieving a smooth transition.

[0037] The working principle of this embodiment is as follows: first, the adjusting screw 10 is driven to rotate by an external driving device, and the adjusting frame 9 moves laterally along the adjusting screw 10, and the marking mechanism 5 is driven to move laterally as a whole through the connecting plate 8 and the guide rod 7 to adapt to the needs of different marking positions on the plate. Then, when the ABS plate enters the conveying structure 1, the lifting plate 65 at the bottom of the adapting wheel 64 in the adapting mechanism 6 first contacts the surface of the plate. When the plate is conveyed, its front end first contacts the front end surface of the lifting plate 65 at the bottom of the adapting wheel 64. As the plate continues to move, the bottom lifting plate 65 is pushed forward, driving the adapting wheel 54 to rotate. At this time, the front lifting plate 65 rotates to the lowest point with the adapting wheel 54, and its end contacts the top surface of the plate, thereby The mounting frame 63 is automatically lifted and drives the moving rod 62 to move upward. The moving rod 62 simultaneously drives the lifting plate 66 to rise. The lifting plate 66 pushes the storage box 531 to move upward along the guide rod 7 through the guide plate 67, thereby driving the entire marking mechanism 5 to rise, completing the initial adaptive adjustment of the distance between the marking head 54 and the plate surface to adapt to plates of different thicknesses. Moreover, since the lifting plates 65 are evenly distributed along the circumference of the adaptation wheel 64, when the front lifting plate 65 contacts the plate, the bottom lifting plate 65 has been separated from the front end surface of the plate, and the subsequent lifting plates 65 rotate in turn to contact the top surface of the plate to form a continuous support. The continuous support makes the marking mechanism 5 highly stable, so there is no height fluctuation at the moment of marking action, ensuring the marking quality.

[0038] During the marking process, the external driving device drives the rotating shaft 541 to rotate, and the shaft sleeve 542 drives the fixed rod 543, the sliding sleeve 544 and the marking plate 547 to rotate. When the pushing block 548 moves along the inner wall of the arc guide rail 51, the inclined portion of the arc guide rail 51 generates pressure on the arc portion of the pushing block 548, and the pushing block 548 drives the sliding sleeve 544 to slide on the fixed rod 543, compressing the second return spring 545, causing the marking plate 547 to retract inward and away from the surface of the plate. When the pushing block 548 moves to the notch-shaped part at the bottom of the arc guide rail 51, the constraint of the arc guide rail 51 is lost, and the second return spring 545 is reset, pushing the sliding sleeve 544 and the marking plate 547 to extend outward. The marking plate 547 contacts the surface of the plate and generates a certain pressure, printing the marking information on the plate. Continuing to rotate, the push block 548 leaves the gap and contacts the end of the arc guide rail 51 again through the arc portion 15 and the inclined transition structure on the side of the push block 548. The inclination angle of the inclined portion 14 causes the push block 548 to be subjected to a radially inward component of the arc guide rail 51, driving the sliding sleeve 544 to compress the second return spring 545, thereby achieving a smooth contraction of the marking head 54. When it moves to the ink replenishing component 53, the marking plate 547 contacts the adsorption sponge 534, pushing the movable plate 536 and the movable rod 537 upward, the elastic sleeve 538 is compressed, and the movable rod 537 drives the blocking ball 532c to move out of the fixed ring 532b through the connecting rod 532d. The ink in the storage box 531 flows into the shell 533 through the connecting tube 532a and is absorbed by the adsorption sponge 534, thereby achieving ink replenishment for the marking head 54.

[0039] Example 2: Based on Example 1, Figure 8 The cam 24 is connected to the bottom of the conveying structure 1 by means of a screw 22 and a fixing frame 25 is connected to the fixing frame 25 on the side opposite to the moving plate 23. The front and rear sides of the fixing frame 25 are both rotatably provided with a holding wheel 26. The surface threads of the two screws 22 on both sides are arranged in opposite directions. By setting the centering holding structure 2, the screw 22 can be driven to rotate by the shaft 21, and the screw 22 and the moving plate 23 can cooperate with each other to make the moving plates 23 on both sides move relative to or oppositely. The spacing between the holding wheels 26 on both sides can be adjusted to realize automatic centering of the plate, thereby adapting to the automatic positioning of plates of different widths and avoiding the problem of marking position deviation caused by plate offset.

[0040] Among them, the bottom of the conveying structure 1 is bolted with a driving motor, and the output end of the driving motor is bolted with a driving shaft 11. The surfaces of the driving shaft 11 and the shaft rod 21 are both sleeved with synchronous wheels 12, and a synchronous belt 13 is wound between the insides of two adjacent synchronous wheels 12. By setting the driving shaft 11, synchronous wheels 12 and synchronous belt 13, the driving shaft 11 is driven to rotate by the driving motor, and under the action of the synchronous wheels 12 and the synchronous belt 13, the effect of synchronous rotation of the two shaft rods 21 is achieved, so that the retaining wheels 26 on the front and rear sides can be displaced synchronously to ensure the effect of centering the plate.

[0041] The working principle of this embodiment is as follows: After the drive motor is started, the drive shaft 11 rotates, driving the two shafts 21 to rotate synchronously through the synchronous wheel 12 and the synchronous belt 13. Since the threads of the screws 22 on both sides are in opposite directions, when the shafts 21 rotate, the movable plates 23 on both sides move toward or away from each other along the screws 22. When the movable plates 23 move toward each other, they drive the fixed frame 25 and the retaining wheel 26 to move toward the center through the connecting shaft 24; When moving in opposite directions, they move away from the center. According to the width of the plate, the spacing between the holding wheels 26 is adjusted so that the plate is clamped between the holding wheels 26 on both sides to achieve automatic centering; after the plate enters the conveying structure 1, the holding wheels 26 on both sides initially clamp the edge of the plate, and the rotation of the shaft 21 drives the screw 22 to transmit. The movable plate 23 automatically adjusts the spacing between the holding wheels 26 according to the width of the plate. The holding wheels 26 contact the edge of the plate and apply appropriate pressure to offset the lateral deviation during the conveying process of the plate, so that the plate always moves along the central axis of the conveying structure 1. When the holding wheels 26 contact the plate, the elastic action of the holding wheels 26 made of rubber buffers the tension fluctuations in the conveying of the plate, avoids deformation of the plate due to tension changes, and ensures the accuracy of the marking position.
