Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label embossing printing technology, specifically a 3D embossing printing device for self-adhesive labels. Background Technology

[0002] Embossing technology involves creating tiny raised or recessed areas on self-adhesive materials to give patterns or text a three-dimensional feel to the touch and visually. Generally, embossing technology is divided into two types: raised embossing and recessed embossing. Raised embossing involves printing bentonite or polymer materials onto the label surface to create raised patterns or text. This method is suitable for thicker label paper, but it is prone to uneven bulging and poor results when the material is thin. Relief printing, on the other hand, uses laser etching or mechanical engraving to create recessed patterns or text on the back of the label. Since the recessed part can be flush with the surface, this method has a significant advantage on thin self-adhesive materials. Among them, Chinese patent number CN202421308292.0 discloses a new type of self-adhesive label printing equipment, which has a mechanism for supporting the conveyor belt, so that the self-adhesive label products are tightly attached to the bottom of the printing cylinder, thus enhancing the efficiency and effect of the printing equipment. It includes a conveying component, a support frame, a drive component, and a printing cylinder. The printing cylinder is set in the top area of ​​the support frame, the drive component is set in the left end of the support frame, the conveying component is set in the bottom end of the printing cylinder, and the support mechanism is set in the middle of the support frame.

[0003] Based on the above, the inventors have discovered the following problems: The above-mentioned patent can adjust the height of the support mechanism to adapt to the printing of various self-adhesive labels and can enhance the efficiency and effect of printing equipment, but it does not have the effect of embossed printing, resulting in a relatively limited range of self-adhesive labels to be produced. Furthermore, dust may fall onto the label surface during the printing process, affecting the subsequent color printing effect of the self-adhesive labels. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 The present invention provides a technical solution as follows:

[0023] Example:

[0024] In this embodiment, a 3D embossed printing device for self-adhesive labels includes a base 1 and a label tape 3. A take-up roller 2 is provided on one side of the base 1, a feed roller 4 is provided on one side of the take-up roller 2, a limiting roller group 7 is provided on one side of the feed roller 4, and a laser etching mechanism 5 is provided on one side of the limiting roller group 7. The laser etching mechanism 5 has auxiliary components, and a printing mechanism 9 is provided at its lower end. The feed roller 4, laser etching mechanism 5, limiting roller group 7, and printing mechanism 9 are all mounted on the base 1. One end of the label tape 3 is connected to the feed roller 4, and the other end of the label tape 3 passes sequentially through the limiting roller group 7. The laser etching mechanism 5 and the printing mechanism 9 are connected to the receiving roller 2. Several rotating rollers 6 are provided on the machine base 1 and on the side of the label tape 3. A motor 18 is provided on the side of the machine base 1 away from the laser etching mechanism 5. One end of the limiting roller group 7 passes through the upper end of the machine base 1 and is provided with a drive shaft. The drive shaft is provided with belt drive group three 22, belt drive group two 20 and belt drive group one 19. The end of belt drive group three 22 away from the drive shaft is connected to a connecting shaft 23. The end of belt drive group two 20 away from the drive shaft is connected to the output end of the motor 18. The end of belt drive group one 19 away from the drive shaft is connected to the feeding roller 4.

[0025] The label tape 3 moves to the laser etching mechanism 5 and pauses briefly for etching by the laser etching mechanism 5. Then, it is printed on the printing mechanism 9 and finally wound up by the take-up roller 2.

[0026] Among them, motor 18 is a power drive mechanism. The rotation of motor 18, together with the cooperation of belt drive group 20, drives the limit roller group 7 to rotate synchronously. The drive shaft on the limit roller group 7, in conjunction with the action of belt drive group 19, drives the feeding roller 4 to rotate synchronously. The feeding roller 4, the limit roller group 7, and the receiving roller 2 can drive the label tape 3 to perform precise conveying motion on this device.

[0027] Furthermore, the rotating shaft on the limiting roller group 7, combined with the design of the belt drive group 22, can drive the connecting shaft 23 to rotate.

[0028] The auxiliary components include a pressure frame 16, a connecting plate 11 at the lower end of the laser etching mechanism 5, a connecting frame 13 at the lower end of the connecting plate 11, a plurality of springs 17 evenly distributed at the lower end of the connecting frame 13, the plurality of springs 17 being connected to the upper end of the pressure frame 16, a limiting plate 10 at the lower end of the pressure frame 16 and located on the base 1, the laser etching mechanism 5, the connecting frame 13, the pressure frame 16 and the limiting plate 10 being arranged in parallel to each other, and the label tape 3 passing through the gap between the limiting plate 10 and the pressure frame 16;

[0029] Through the action of the pressure frame 16, spring 17 and limiting plate 10, the label tape 3 can remain stable when it is etched by the laser etching mechanism 5, making the etching of the label tape 3 more stable and ensuring the etching quality of the label tape 3.

[0030] The pressure frame 16 has a movable hole 33 on one side of the base 1. A connecting frame 32 is provided in the movable hole 33, and one end of the connecting frame 32 is connected to the side of the pressure frame 16. A connecting plate 29 is provided at the lower end of the movable hole 33 and on the side of the base 1. A slider 27 is provided on the side of the connecting frame 32 near the base 1. A limiting groove 28 is provided on the connecting plate 29, and the limiting groove 28 is movably connected to the slider 27. A movable plate 26 is provided on the side of the connecting frame 32 away from the slider 27. An inclined surface 39 is provided on one side of the movable plate 26, and the lower end of the movable plate 26 is attached to a... A rack 25 is provided with a special-shaped gear 24 at its lower end and on the side of the base 1. The special-shaped gear 24 is mounted on the connecting shaft 23. The special-shaped gear 24 includes a tooth section 38 and an arc section 37. A pair of tooth sections 38 are provided on the special-shaped gear 24, and an arc section 37 is provided between the tooth sections 38. One of the tooth sections 38 meshes with the rack 25. A second spring 36 is provided on the side of the rack 25 away from the moving plate 26. The second spring 36 is connected to a fixing block 34, and the fixing block 34 is fixedly mounted on the connecting plate 29.

[0031] The rotation of the connecting shaft 23 drives the shaped gear 24 to rotate synchronously, which in turn drives the rack 25 to move horizontally and pushes the moving plate 26 to move vertically along the limiting groove 28. With the cooperation of the movable hole 33 and the connecting frame 32, the pressure frame 16 can be driven to move vertically away from the limiting plate 10 and the label tape 3, thereby releasing the fixing effect of the label tape 3 on the limiting plate 10. At this time, the unetched label tape 3 on one side of the laser etching mechanism 5 can be smoothly moved to the upper end of the limiting plate 10 under the action of the motor 18, the feeding roller 4, the limiting roller group 7 and the receiving roller 2. At this time, the tooth section 38 on the shaped gear 24 that meshes with the rack 25 rotates to the tail of the tooth section 38. Then, under the action of the arc section 37 and the second spring 36, the rack 25 can be driven to move away from the moving plate 26 along the moving groove 30. Under the action of spring 17, the pressure frame 16 presses and fixes the unetched label tape 3 on the limiting plate 10. Then, the motor 18 is turned off, and the laser etching mechanism 5 is started to etch the label tape 3. When the label tape 3 is etched, the motor 18 is started again to continue rotating, so that the other tooth section 38 of the special gear 24 can continue to drive the rack 25 to push the moving plate 26, so that the pressure frame 16 moves away from the limiting plate 10, releasing the fixing effect of the label tape 3. At the same time, the synchronous rotation of the feeding roller 4, the limiting roller group 7 and the receiving roller 2 can drive the next part of the unetched label tape 3 to the limiting plate 10, so that the etching operation can be repeated. In summary, the movement of the pressure frame 16 does not require a separate power source, saving power consumption and reducing the operating cost of this device.

[0032] Wherein, the arc length of the tooth interval 38 is equal to the length of the pressure frame 16;

[0033] By designing that the arc length of the toothed section 38 is equal to the length of the pressure frame 16, when the toothed section 38 drives the rack 25 to move horizontally, it can drive the rack 25 to push the inclined surface 39 on the moving plate 26, so that the moving plate 26 moves vertically for a period of time. This time is the same as the start and end time of engagement between a certain toothed section 38 and the rack 25, and is the same as the time when the un-etched label tape 3 segment on one side of the laser etching mechanism 5 runs to the upper end of the limiting plate 10.

[0034] The rack 25 is provided with a retaining plate 31 on the side near the connecting plate 29, and the connecting plate 29 is provided with a moving groove 30, which is movably connected to the retaining plate 31.

[0035] The design of the clamping plate 31 and the moving groove 30 can limit the movement of the rack 25, allowing the rack 25 to move horizontally along the moving groove 30.

[0036] Among them, the first spring 17 is provided with a limiting post 15, and the second spring 36 is provided with a guide post 35. The fixing block 34 is provided with a through hole, and the guide post 35 is movably connected to the through hole.

[0037] The design of guide post 35 and fixing block 34 can limit the movement direction of spring 2 36, making the horizontal movement of rack 25 more stable. The design of limiting post 15 can guide the movement direction of spring 1 17, making the vertical movement of spring 1 17 accurate. This allows the pressure frame 16 to stably and accurately fix part of the label tape 3 on the upper end of the limiting plate 10, facilitating the accuracy of laser etching mechanism 5 in processing the label tape 3.

[0038] The pressure frame 16 is provided with a telescopic cover 8 on its outer side. The telescopic cover 8 is connected to the lower end of the connecting frame 13. The connecting frame 13 is connected through an air pipe 14. The air pipe 14 is connected to a vacuum cleaner 21. The receiving roller 2 is provided with a power drive device on its side.

[0039] The design of the air tube 14 and the vacuum cleaner 21 can remove the dust generated when the laser etching mechanism 5 etches the label tape 3 in time, so as to avoid affecting the printing operation of the label tape 3 at the printing mechanism 9. The design of the telescopic cover 8 can prevent dust from splashing during the etching operation of the label tape 3. The combination of the vacuum cleaner 21 and the air tube 14 can increase the cleaning effect of the laser etching mechanism 5.

[0040] The rotation of the receiving roller 2, the discharging roller 4, and the limiting roller group 7 can drive the label tape 3 to move stably on this device.

[0041] Working principle: When using this device, the label tape 3 roll is placed on the feeding roller 4, and one end of the label tape 3 passes through the limiting roller group 7, the pressure frame 16 and the limiting plate 10, the printing mechanism 9 and several rotating rollers 6 in sequence and is connected to the receiving roller 2. The label tape 3 moves to the laser etching mechanism 5 and pauses briefly for etching by the laser etching mechanism 5. Then, the printing operation is performed on the printing mechanism 9, and finally the receiving roller 2 rewinds it.

[0042] Among them, motor 18 is a power drive mechanism. The rotation of motor 18, together with the cooperation of belt drive group 20, drives the limit roller group 7 to rotate synchronously. The drive shaft on the limit roller group 7, in conjunction with the action of belt drive group 19, drives the feeding roller 4 to rotate synchronously. The feeding roller 4, the limit roller group 7, and the receiving roller 2 can drive the label tape 3 to perform precise conveying motion on this device.

[0043] Furthermore, the rotating shaft on the limiting roller group 7, combined with the design of the belt drive group 22, can drive the connecting shaft 23 to rotate, which in turn drives the special gear 24 to rotate. This allows the rack 25 to move horizontally and pushes the moving plate 26 to move vertically along the limiting groove 28. With the cooperation of the movable hole 33 and the connecting frame 32, the pressure frame 16 can move vertically away from the limiting plate 10 and the label tape 3, thereby releasing the fixing effect of the label tape 3 on the limiting plate 10. At this time, the unetched label tape 3 on one side of the laser etching mechanism 5 can move smoothly to the upper end of the limiting plate 10 under the action of the motor 18, the feeding roller 4, the limiting roller group 7, and the receiving roller 2. At this time, the tooth section 38 on the special gear 24 that meshes with the rack 25 rotates to the tail of the tooth section 38.

[0044] Then, under the action of the arc-shaped section 37 and the second spring 36, the rack 25 can be driven to move away from the moving plate 26 along the moving groove 30, so that the pressure frame 16, under the action of the first spring 17, can press and fix the unetched label tape 3 on the limiting plate 10; then the motor 18 is turned off and the laser etching mechanism 5 is started to etch the label tape 3.

[0045] When the label tape 3 is etched, the motor 18 is restarted to continue rotating, so that the other tooth section 38 of the special gear 24 can continue to drive the rack 25 to push the moving plate 26, so that the pressure frame 16 moves away from the limiting plate 10, releasing the fixing effect of the label tape 3. At the same time, the synchronous rotation of the feeding roller 4, the limiting roller group 7 and the receiving roller 2 can drive the next part of the unetched label tape 3 to move to the limiting plate 10, so that the etching operation can be repeated.

[0046] The pressure frame 16, spring 17, and limiting plate 10 ensure that the label tape 3 remains stable during the etching process of the laser etching mechanism 5, making the etching of the label tape 3 more stable and guaranteeing the etching quality of the label tape 3. When the pressure frame 16 is tightly attached to the upper end of the label tape 3, the vacuum cleaner 21 can thoroughly remove the dust generated during the operation of the laser etching mechanism 5 with the cooperation of the telescopic cover 8, ensuring the printing effect of the label tape 3 at the printing mechanism 9. At the same time, the movement of the pressure frame 16 does not require a separate power source, saving power consumption and reducing the operating cost of the device.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
