Description

Technical Field

[0001] This utility model belongs to the field of molding technology, and specifically relates to a rapid prototyping mold for anti-counterfeiting embossing of tobacco packaging boxes. Background Technology

[0002] As a high-value-added industry, the tobacco industry relies heavily on embossed anti-counterfeiting marks on its packaging for brand protection, consumer rights maintenance, and market order management. Their anti-counterfeiting performance directly impacts brand reputation and consumer rights. ^p Using specific molds to press anti-counterfeiting marks onto tobacco boxes is a common technique used by companies. This creates anti-counterfeiting indentations with specific patterns and structures on the tobacco box. The depth of these indentations often affects the anti-counterfeiting effect and subsequent processing quality. However, existing molds struggle to control and adjust the depth of the indentations during pressing, failing to meet the tobacco industry's demand for efficient and high-quality anti-counterfeiting indentations. ^p Referring to Chinese patent document CN208099068U, entitled "Indentation Forming Mold," the invention includes a base, a pressing head seat, a pressing head, and a pad. The base... Utility Model Content

[0003] The technical problem to be solved by this utility model is: when performing anti-counterfeiting embossing on tobacco boxes, the depth of the embossing can be adjusted quickly and accurately to achieve rapid and high-quality anti-counterfeiting embossing forming of tobacco packaging boxes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rapid prototyping mold for anti-counterfeiting embossing of tobacco packaging carton, including a support frame, a lifting rod and an embossing plate. An adjusting ring is sleeved on the lifting rod, and a first stop block is provided on the adjusting ring. A second stop block is installed on the lifting rod above the first stop block. A right-angle bevel gear is installed on the adjusting ring and located on the support frame. An internal thread is provided on the outer surface of the adjusting ring, and an external thread that meshes with the internal thread is provided on the right-angle bevel gear. A rotating handwheel is connected to the right-angle bevel gear.

[0005] By adopting the above technical solution, rotating the right-angle bevel gear can drive the adjusting ring to move vertically, thereby allowing the first stop block to move closer to or further away from the second stop block. When the lifting rod drives the indentation plate to imprint downwards, the first stop block and the second stop block can cooperate to limit the lifting rod, thereby achieving rapid and accurate adjustment of the indentation depth.

[0006] Optionally, the lifting rod is equipped with scale lines.

[0007] By adopting the above technical solution, when adjusting the distance between the first and second stop blocks by vertically sliding the adjusting ring, the staff can easily make adjustments by referring to the scale lines.

[0008] Optionally, the lifting rod is equipped with a locking assembly for replacing the indentation plate. The locking assembly includes a through hole one on the lifting rod, a connecting block on the indentation plate, a connecting groove on the connecting block, the lifting rod being installed on the connecting groove, a through hole two on the connecting groove and the connecting block, bolts being installed on the through hole one and the through hole two, and the connection between the connecting groove and the lifting rod being set as a spiral installation.

[0009] By adopting the above technical solution, the spiral connection between the connecting groove and the lifting rod facilitates the disassembly of the imprint plate. The bolts ensure the stability of the imprint plate when pressed down. The easy disassembly design allows for convenient replacement of the anti-counterfeiting imprint template, improving the practicality of the device.

[0010] Optionally, a handle may be provided on the bolt.

[0011] By adopting the above technical solution, the handle can enhance the convenience for staff when replacing the indentation plate.

[0012] Optionally, a protective housing is installed on the support frame to protect the right-angle bevel gear.

[0013] By adopting the above technical solution, the protective shell can prevent the right-angle bevel gear from coming into contact with workers, thus ensuring the safety of the working environment.

[0014] Optionally, a shock-absorbing rubber pad is installed on the stop block.

[0015] By adopting the above technical solution, when the first stop block and the second stop block come into contact, the shock-absorbing rubber pad prevents the first stop block from directly impacting the second stop block, which can reduce the noise generated by the impact and at the same time buffer the lifting rod, further protect the lifting rod, and improve the service life of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] Firstly, by adjusting the internal thread on the ring and the external thread on the right-angle bevel gear, the vertical adjustment of the lifting rod can be achieved simply by turning the handwheel, changing the distance between the first and second stop blocks, and controlling the depth of the anti-counterfeiting indentation. Compared with existing technologies, this device has a simple structure and is convenient for staff to adjust and control the depth of the indentation, improving the accuracy and convenience of adjustment.

[0018] Secondly, the embossing plate is installed on the lifting rod by a screw, which makes it convenient for staff to replace the anti-counterfeiting embossing plate for different templates. At the same time, it ensures the stability of the embossing plate when pressed down. The bolt setting can strengthen the tightness between the embossing plate and the lifting rod, further enhancing the stability of the embossing plate when pressed down. The design of the locking component not only enhances the stability and precision of the mold, but also improves the flexibility and practicality of the mold, allowing operators to replace different embossing plates as needed to adapt to different anti-counterfeiting requirements.

[0025] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0026] like Figure 1-4As shown, a rapid prototyping mold for anti-counterfeiting embossing on tobacco packaging cartons includes a support frame 1, an adjustment component 2, and a locking component 3. A lifting rod 11 and an embossing plate 12 are mounted on the support frame 1. The adjustment component 2 includes an adjustment ring 21. The lifting rod 11 is driven by an externally connected drive cylinder, causing it to slide vertically back and forth. The embossing plate 12 is spirally mounted on the bottom of the lifting rod 11 and is detachable for easy replacement of different embossing plates 12. The adjustment ring 21 is sleeved on the lifting rod 11. The adjustment component 2 is used to move the adjustment ring 21 closer to or away from the upper part of the lifting rod 11. The locking component 3 is used to lock the embossing plate 12, further improving the tightness of the connection between the embossing plate 12 and the lifting rod 11.

[0027] like Figure 2 and Figure 3 As shown, the adjusting assembly 2 includes a stop block 1 22, a stop block 23, a scale line 27, and a shock-absorbing rubber pad 28. A stop block 1 22 is installed on the top of the adjusting ring 21, and a stop block 23, located above the stop block 1 22, is installed on the lifting rod 11. A scale line 27 is provided on the lifting rod 11 between the stop block 1 22 and the stop block 23, allowing staff to easily observe the distance between them. A shock-absorbing rubber pad 28 is installed on the stop block 1 22. When the stop block 23 moves down synchronously with the lifting rod 11, the shock-absorbing rubber pad 28 prevents direct collision between the stop block 1 22 and the stop block 23, thus providing shock absorption and reducing noise generated by the impact.

[0028] The adjustment assembly 2 also includes a right-angle bevel gear 24, an internal thread 25, an external thread, and a rotating handwheel 26. The support frame 1 is provided with a protective housing 13 and a sealed bearing 242. A support ring 241 is connected to the right-angle bevel gear 24. A right-angle bevel gear 24 is mounted on the adjusting ring 21 and located on the support frame 1. A protective shell 13 is mounted on the support frame 1 and covers the right-angle bevel gear 24. The protective shell 13 has holes for the lifting rod 11 and the adjusting ring 21 to pass through. A support ring 241 is coaxially mounted on the transversely distributed gears of the right-angle bevel gear 24. A sealed bearing 242 is installed inside the protective shell 13. The support ring 241 is sleeved on the sealed bearing 242. The support ring 241 and the sealed bearing 242 are used to support the transverse gears of the right-angle bevel gear 24. A rotating shaft is coaxially mounted on the vertical gear of the right-angle bevel gear 24. A rotating handwheel 26 is connected to the rotating shaft. The rotating handwheel 26 passes through the protective shell 13 and is located outside the protective shell 13. An internal thread 25 is provided on the outer surface of the adjusting ring 21. An external thread is provided on the transverse gear of the right-angle bevel gear 24. The external thread meshes with the internal thread 25.

[0029] like Figure 1 and Figure 4As shown, the locking assembly 3 includes a through hole 31, a connecting block 32, a connecting groove 33, a second through hole 34, a bolt 35, and a handle 36. The first through hole 31 is formed on the lifting rod 11. The top of the indentation plate 12 is provided with a connecting block 32, and a connecting groove 33 is formed on the connecting block 32. The connection between the inside of the connecting groove 33 and the lifting rod 11 is screwed together, which facilitates the replacement of indentation plates 12 of different specifications and templates. The second through hole 34 is formed on the connecting groove 33 and the connecting block 32. The bolt 35 is installed on the first through hole 31 and the second through hole 34. The bolt 35 can further enhance the tightness of the connection between the indentation plate 12 and the lifting rod 11. A handle 36 is provided on the bolt 35 to facilitate the removal of the bolt 35.

[0030] Working principle: When in use, firstly, according to the required anti-counterfeiting embossing depth, rotate the handwheel 26 to drive the right-angle bevel gear 24 to rotate. The external thread on the right-angle bevel gear 24 meshes with the internal thread 25 on the adjusting ring 21, which allows the adjusting ring 21 to slide vertically on the lifting rod 11, thereby causing the first stop block 22 to move closer to or further away from the second stop block 23. By observing the scale line 27, the operator can make fine adjustments to the distance between the first stop block 22 and the second stop block 23, so that the same embossing depth can be quickly adjusted next time.

[0031] When anti-counterfeiting embossing is required on tobacco packaging cartons, the tobacco packaging cartons are placed under the embossing plate 12. Then, the drive cylinder is activated, which drives the lifting rod 11 to slide vertically back and forth. The lifting rod 11 drives the embossing plate 12 to move downward. When the embossing plate 12 contacts the tobacco packaging cartons, it continues to move downward, squeezing the tobacco packaging cartons to form anti-counterfeiting embossing. During the embossing process, the first stop block 22 and the second stop block 23 limit the lifting rod 11 to prevent it from moving too far and causing the embossing to be too deep. After the embossing is completed, the drive cylinder drives the lifting rod 11 and the embossing plate 12 to reset, and the tobacco packaging cartons can be removed.

[0032] In addition, when it is necessary to replace different anti-counterfeiting embossing templates, the bolts 35 can be loosened, the connecting block 32 can be removed from the lifting rod 11, and then a new embossing plate 12 can be installed. The connecting block 32 and the lifting rod 11 can then be connected by threads and the bolts 35 can be tightened.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
