Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically, to an auxiliary device for inkjet coding of tubular materials. Background Technology

[0002] Currently, some cosmetics are packaged in tubular containers, which require inkjet printers to mark information such as production date and batch number during the production process. To achieve accurate coding, auxiliary devices are needed to position and stably convey the tubular material, ensuring that the material remains fixed in posture, without shifting or rotating, during the coding process.

[0003] Existing inkjet coding auxiliary devices for tubular materials have the following shortcomings: First, the positioning structure is mostly designed with a fixed spacing, which is not adaptable to tubular materials of different diameters; Second, some devices with adjustable spacing use a sliding adjustment mechanism, which is complex in structure and easy to loosen after adjustment, resulting in a decrease in positioning accuracy during the conveying process. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for inkjet printing of tubular materials to solve the problems of poor adaptability and insufficient inkjet printing accuracy in the prior art.

[0005] The embodiments of this utility model are achieved through the following technical solutions: A coding auxiliary device for tubular materials includes a frame positioned below a coding machine. The frame is equipped with a conveying mechanism, a positioning structure, a spacing adjustment mechanism, a positioning stabilization mechanism, and a coding adapter mechanism. The positioning structure is mounted on the conveying mechanism to achieve orderly positioning and transportation of the tubular material, facilitating precise coding of the material's surface by the coding machine. The spacing adjustment mechanism is used to change the shape of the positioning structure to adjust the spacing between adjacent positioning structures. The positioning stabilization mechanism is positioned corresponding to the coding station. The coding adapter mechanism works in conjunction with an external coding machine.

[0006] In some embodiments, the conveying mechanism is a belt conveyor driven by a motor, and the positioning structure is a positioning bar arranged at intervals along the conveying direction of the belt conveyor, with adjacent positioning bars forming a V-shaped groove; the positioning bar is adapted to the spacing adjustment mechanism, and the two are detachably coupled.

[0007] In some embodiments, the spacing adjustment mechanism includes a shape adjustment component corresponding to each positioning strip and an independent locking unit; the shape adjustment component is disposed on both sides of the positioning strip and is used to independently change the extension length of the corresponding positioning strip, thereby adjusting the gap width between adjacent positioning strips; the independent locking unit is used to fix the adjusted shape of the positioning strip.

[0008] In some embodiments, the shape adjustment component includes splicing unit segments that match the shape of the positioning strip. Each splicing unit segment has a boss and a slot at both ends. Adjacent splicing unit segments are connected by fitting the boss and the slot. The extension length of the positioning strip is changed by increasing or decreasing the number of splicing unit segments or adjusting the fitting depth, thereby adjusting the gap width between adjacent positioning strips. The positioning strip also has bosses and slots on both sides for adapting and connecting with the splicing unit segments.

[0009] In some embodiments, both the boss and the slot of the splicing unit segment are provided with through locking holes. The locking holes are opened along the extension direction of the positioning strip and are used to cooperate with the independent locking unit to achieve positioning. The independent locking unit is a threaded locking member with an anti-slip structure. The threaded locking member passes through the locking hole and locks and fixes the splicing unit segment by tightening it against the mating surface of the boss and the slot.

[0010] In some embodiments, the boss, slot, and locking hole are all located at corresponding positions of the positioning bar near the conveyor belt, and do not protrude from the inner sidewall of the V-shaped groove of the positioning bar, so as to prevent surface damage caused by contact with tubular materials.

[0011] In some embodiments, the positioning strip has a trapezoidal structure and anti-slip texture on its sidewalls; the positioning strip is fixedly connected to the conveyor belt.

[0012] In some embodiments, the positioning stabilization mechanism includes two guide plates symmetrically arranged on both sides of the conveying mechanism and extending along the conveying direction; the frame is provided with a locking mechanism for adjusting and locking the position of the guide plates, and the guide plates are located directly below the inkjet printer.

[0013] In some embodiments, the locking mechanism includes a vertical rod and a clamping member; the bottom end of the vertical rod is fixedly disposed on the outside of the frame, and the vertical rod is slidably sleeved inside the vertical clamping hole of the clamping member. The clamping member is also provided with a horizontal clamping hole, and a horizontal rod is slidably sleeved in the horizontal clamping hole. The horizontal rod is fixedly connected to the outside of the guide plate at one end near the frame; both the vertical clamping hole and the horizontal clamping hole are tightened with bolt assemblies to abut against the vertical rod or the horizontal rod, thereby achieving clamping and locking of the clamping member with the vertical rod and the horizontal rod.

[0014] In some embodiments, the inkjet printing adapter mechanism includes a photoelectric trigger sensor; the photoelectric trigger sensor is fixedly mounted above the frame, arranged in front of the inkjet printing station, and connected to an external inkjet printer signal.

[0015] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects: 1. This device, through its adjustable spacing structure combining splicing unit segments and threaded locking components, can flexibly adapt to tubular materials of different diameters. Adjustment is convenient and locking is stable, eliminating the need for complete replacement of the positioning components. The positioning strip uses a snap-on detachable connection, and the design of the boss, slot, and locking hole not protruding from the inner wall of the V-shaped groove facilitates maintenance and prevents scratching the material surface. The positioning stabilization mechanism, through the combined action of a bidirectional adjustable guide plate and the anti-slip texture of the positioning strip, effectively limits the lateral offset and circumferential rotation of the material. Combined with the synchronous linkage between the photoelectric trigger sensor and the inkjet printer, it significantly improves inkjet printing accuracy, simplifies changeover operations, and increases production efficiency. The overall structure is simple, practical, and highly adaptable. Attached Figure Description

[0024] Please see Figures 1-4 As shown, the main body of this embodiment is a tubular material inkjet printing auxiliary device, which is installed directly below the inkjet printer 1. The core consists of a frame 2, a conveying mechanism, a positioning structure, a spacing adjustment mechanism, a positioning stabilization mechanism, and an inkjet printing adapter mechanism. The frame 2 supports all functional components; the conveying mechanism is arranged horizontally on the frame 2; the positioning structure is mounted on the surface of the conveying mechanism; the spacing adjustment mechanism is located on both sides of the positioning structure; the positioning stabilization mechanism faces the inkjet printing station; and the inkjet printing adapter mechanism is installed above the frame 2 near the inkjet printer 1. All mechanisms work together to achieve synchronized material positioning, conveying, and inkjet printing.

[0025] Furthermore, the conveying mechanism employs a belt conveyor driven by a stepper motor 3. The stepper motor 3 is connected to the drive roller 4 of the belt conveyor, driving the conveyor belt 5 to run at a uniform speed along a set direction. The positioning structure consists of several positioning strips 6 evenly spaced along the conveying direction of the conveyor belt 5. The positioning strips 6 are trapezoidal in shape, and adjacent positioning strips 6 form a V-shaped groove for accommodating tubular materials. The sidewalls of the positioning strips 6 are provided with anti-slip textures to enhance friction with the tubular materials. The positioning strips 6 are fixedly connected to the conveyor belt 5 with bolts for easy maintenance or replacement.

[0026] Furthermore, the spacing adjustment mechanism includes a shape adjustment component corresponding to each positioning strip 6 and an independent locking unit. The shape adjustment component is a splicing unit segment 20 that matches the shape of the positioning strip 6. Both ends of the splicing unit segment 20 are integrally formed with a boss 7 and a slot 8, respectively. The two sides of the positioning strip 6 are also provided with matching bosses 7 and slots 8. Adjacent splicing unit segments 20 and splicing unit segments 20 and positioning strip 6 are engaged and connected through bosses 7 and slots 8.

[0027] Furthermore, the splicing unit segment 20 has through-hole locking holes 9 at both the boss 7 and the slot 8. The locking holes 9 are arranged along the extension direction of the positioning strip 6, and the boss 7, slot 8, and locking holes 9 are all located at corresponding positions on the positioning strip 6 near the conveyor belt 5, so as not to protrude from the functional area of ​​the inner sidewall of the V-shaped groove (the sidewall of the positioning strip 6). The independent locking unit is a threaded locking part 10 with anti-slip texture. The threaded locking part 10 is threadedly adapted to the locking hole 9. After being screwed in, it can abut against the mating surface of the boss 7 and the slot 8, thereby fixing the splicing unit segment 20 to the positioning strip 6.

[0028] Furthermore, the positioning and stabilizing mechanism includes two symmetrically arranged guide plates 11, which extend along the conveying direction of the conveying mechanism and are directly opposite the inkjet printing station below the inkjet printer 1. The guide plate 11 is connected to the frame 2 via a locking mechanism, which consists of a vertical rod 12, a clamping member 13, and a horizontal rod 14. The bottom end of the vertical rod 12 is fixed to the outside of the frame 2. The clamping member 13 has a vertical clamping hole 15 and a horizontal clamping hole 16. The vertical rod 12 slides through the vertical clamping hole 15, and the horizontal rod 14 slides through the horizontal clamping hole 16. The end of the horizontal rod 14 near the frame 2 is fixedly connected to the outside of the guide plate 11. Both the vertical clamping hole 15 and the horizontal clamping hole 16 are equipped with adjustment grooves 17 that communicate with the outside of the clamping member 13. The clamping member 13 is provided with bolt assemblies 18 that pass through the adjustment grooves 17. By tightening the bolt assemblies 18, the vertical rod 12 and the horizontal rod 14 can be respectively tightened, thereby realizing the adjustment and locking of the vertical and horizontal positions of the guide plate 11.

[0029] Furthermore, the inkjet printing adapter is a photoelectric trigger sensor 19. The sensor 19 is fixed above the frame 2 by a bracket and is arranged in front of the inkjet printing station. The signal output end of the sensor 19 is connected to the signal input end of the external inkjet printer 1 by wire or wireless means to detect the position of the tubular material and trigger the inkjet printer 1 to print.

[0030] The working process and adjustment method of this device: 1. Spacing Adjustment Operation According to the diameter specifications of the tubular material, adjust the gap width between adjacent positioning strips 6: loosen the threaded locking part 10 of the independent locking unit, and change the extension length of the positioning strip 6 by increasing or decreasing the number of splicing unit segments 20, or adjusting the fitting depth between the splicing unit segment 20 and the positioning strip 6, thereby adjusting the V-shaped groove spacing formed by adjacent positioning strips 6; after the spacing is adjusted to the correct position, screw the threaded locking part 10 into the locking hole 9 and tighten it, so that the boss 7 and the slot 8 fit and fix it, thus completing the spacing locking.

[0031] 2. Positioning and stabilization adjustment Adjust the position of the guide plate 11 according to the material diameter: loosen the bolt assembly 18 on the clamping member 13, slide the clamping member 13 along the vertical rod 12 to adjust the height of the guide plate 11, slide the horizontal rod 14 along the horizontal clamping hole 16 to adjust the distance between the two guide plates 11, and ensure that the guide plate 11 is slightly in contact with the side wall of the material; after adjustment, tighten the bolt assembly 18 to lock the position of the guide plate 11, thereby keeping the material parallel during transportation and preventing skewing.

[0032] 3. Inkjet coding workflow The tubular materials are placed one by one into the V-shaped groove formed by the positioning strip 6. The conveying mechanism is started, and the stepper motor 3 drives the conveyor belt 5 to run at a constant speed. The materials are conveyed synchronously with the belt. When the materials run to the front of the inkjet printing station, the photoelectric trigger sensor 19 detects the materials and sends a signal to the inkjet printer 1. The inkjet printer 1 starts printing synchronously. During the conveying process, the guide plate 11 restricts the lateral deviation of the materials, and the anti-slip texture of the positioning strip 6 prevents the materials from rotating, ensuring the accuracy of the inkjet printing.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
