Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette packaging equipment, and in particular relates to a steel stamping roller system. Background Technology

[0002] In the tobacco industry, the steel stamping roller system is the core device for achieving precise embossing. Through the coordinated operation of the steel stamping roller and the counter roller, it can emboss anti-counterfeiting marks and production information on the surface of cigarette boxes, as well as brand logos on cigarette filters or cigarette paper. The steel stamping roller has text, patterns, or codes pre-engraved on its surface, and a rubber sleeve is fitted onto the counter roller. The substrate to be embossed is laid flat on the rubber sleeve, and by adjusting the pressure between the counter roller and the steel stamping roller, the graphics and text on the steel stamping roller can be completely transferred to the substrate surface.

[0003] During long-term embossing, the surface of the rubber sleeve gradually wears down due to continuous friction, leading to a decrease in the clarity of the embossed characters, necessitating periodic replacement of the rubber sleeve. However, in existing technologies, the rubber sleeve of the pressure roller is generally designed as an integral part of the roller body, requiring the entire pressure roller to be removed and replaced when the rubber sleeve is replaced. This not only significantly increases equipment replacement costs but also prolongs downtime and reduces overall production efficiency. Furthermore, during long-term embossing, the pressure roller and the stamping roller are prone to relative movement due to vibration, wear, and other factors, causing the graphics on the stamping roller to misalign with the rubber sleeve of the pressure roller. This ultimately results in misalignment of the embossed text on the substrate, affecting the production quality of products such as cigarette boxes. However, adjusting the stamping position in existing technologies is extremely inconvenient. It generally requires disassembling the limiting sleeve and drive gear set at the end of the stamping roller before the stamping seat can be calibrated. This entire process is not only complex but also further increases equipment replacement costs and reduces overall production efficiency.

[0004] Therefore, there is an urgent need for a steel printing roller-to-roller system to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel stamping roller system that can not only reduce the cost of steel stamping sleeve position adjustment and improve the efficiency of steel stamping sleeve position adjustment, but also reduce the cost of flexible support sleeve replacement and improve the efficiency of flexible support sleeve replacement.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A steel stamping roller system is provided, comprising:

[0008] A steel stamping roller includes a steel stamping shaft, a limiting component, and several steel stamping sleeves. The steel stamping sleeves are fitted onto the steel stamping shaft, and the limiting component is movably mounted on the steel stamping shaft. The limiting component has a working state of gripping the steel stamping shaft and an adjusting state of loosening the steel stamping shaft. In the working state, the limiting component is used to limit the steel stamping sleeves to the stamping position. In the adjusting state, the position of the steel stamping sleeves on the steel stamping shaft is adjustable.

[0009] The pressure roller includes a pressure shaft, several mounting seats, and several flexible support sleeves. The mounting seats include a first mounting ring and a second mounting ring that are detachably connected. The first mounting ring is connected to the pressure shaft, and each second mounting ring is provided with a flexible support sleeve. At the imprinting position, each flexible support sleeve can contact a steel stamp sleeve.

[0010] Optionally, multiple steel stamp sleeves, mounting bases, and flexible support sleeves are provided, with multiple steel stamp sleeves arranged at intervals along the axial direction of the steel stamp shaft, and multiple flexible support sleeves corresponding one-to-one with multiple steel stamp sleeves.

[0011] Optionally, the stamping roller also includes several first partition rings sleeved on the stamping shaft, with a first partition ring provided between any two adjacent stamping sleeves;

[0012] The pressure roller also includes several second partition rings sleeved on the pressure shaft, with a second partition ring provided between any two adjacent mounting seats.

[0013] Optionally, the limiting member includes a limiting part and a fastening part. The limiting part extends circumferentially along the stamping shaft. In the use state, the fastening part passes through the first end of the limiting part and is fastened to the second end of the limiting part. In the adjustment state, the fastening part separates from the second end of the limiting part.

[0014] Optionally, the fastening part passes through the first end of the limiting part and is threaded into the second end of the limiting part.

[0015] Optionally, the first end of the limiting part is provided with a first connecting hole, the second end of the limiting part is provided with a threaded hole, and the fastening part includes a screw rod, which passes through the first connecting hole and is threadedly engaged with the wall of the threaded hole.

[0016] Optionally, the second mounting ring is provided with a mounting groove extending circumferentially thereon;

[0017] The flexible support sleeve is installed in the mounting groove and is fixedly connected to the groove wall;

[0018] Alternatively, the flexible support sleeve can be fitted into the mounting groove.

[0019] Optionally, the mounting base also includes a fastener that passes through the second mounting ring and is secured to the first mounting ring.

[0020] Optionally, the fastener is threaded to the first mounting ring.

[0021] Optionally, the first mounting ring is provided with a connection position, the connection position is provided with an internal thread, and the fastener is provided with an external thread that mates with the internal thread.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention provides a steel stamping roller system. In the stamping position, each stamping sleeve can contact a flexible support sleeve. Under contact pressure, the stamp on the stamping sleeve is transferred to the substrate laid on the surface of the flexible support sleeve, thus completing the stamping of the image onto the substrate. In operation, the limiting member grips the stamping shaft, restricting the position of the stamping sleeve on the shaft and preventing movement during stamping, ensuring smooth stamping operations. In adjustment, the limiting member loosens its grip on the stamping shaft, allowing the position of the stamping sleeve on the shaft to be adjusted. At this time, the operator can adjust the position between the stamping sleeve and the corresponding flexible support sleeve to ensure that the stamp on the stamping sleeve is always accurately pressed onto the flexible support sleeve, guaranteeing the accuracy of the stamping position. Compared with existing technologies, there is no need to disassemble the limiting member and the drive gear set located at the end of the stamping shaft, making operation convenient and quick, reducing adjustment costs and improving adjustment efficiency. A flexible support sleeve is mounted on the second mounting ring, which is detachably connected to the first mounting ring. When the flexible support sleeve wears out, workers can remove the second mounting ring from the first mounting ring to separate the flexible support sleeve from the pressure roller for replacement, significantly improving replacement efficiency. Moreover, during replacement, only the second mounting ring and the flexible support sleeve need to be replaced, eliminating the need to replace the entire pressure roller, thus reducing replacement costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 4 As shown, this embodiment provides a steel stamping roller system that can not only reduce the cost of adjusting the position of the steel stamping sleeve 13 and improve the efficiency of adjusting the position of the steel stamping sleeve 13, but also reduce the cost of replacing the flexible support sleeve 23 and improve the efficiency of replacing the flexible support sleeve 23.

[0036] See Figure 1The stamping roller system includes a stamping roller 1 and a counterweight roller 2. The stamping roller 1 includes a stamping shaft 11, a limiting member 12, and several stamping sleeves 13. The stamping sleeves 13 are fitted onto the stamping shaft 11. The limiting member 12 is movably mounted on the stamping shaft 11. The limiting member 12 has a working state of gripping the stamping shaft 11 and an adjusting state of loosening the stamping shaft 11. In the working state, the limiting member 12 is used to limit the stamping sleeves 13 to the stamping position. In the adjusting state, the position of the stamping sleeves 13 on the stamping shaft 11 is adjustable. The counterweight roller 2 includes a counterweight shaft 21, several mounting seats 22, and several flexible support sleeves 23. The mounting seat 22 includes a detachably connected first mounting ring 221 and a second mounting ring 222. The first mounting ring 221 is connected to the counterweight shaft 21. Each second mounting ring 222 is provided with a flexible support sleeve 23. In the stamping position, each flexible support sleeve 23 can contact a stamping sleeve 13.

[0037] In the steel stamping roller system provided in this embodiment, at the stamping position, each steel stamp sleeve 13 can contact a flexible support sleeve 23. At this time, the steel stamp on the steel stamp sleeve 13 can be transferred to the substrate laid on the surface of the flexible support sleeve 23 under the action of contact pressure, thereby completing the stamping of the image on the substrate. In the use state, the limiting member 12 is tightly held in the steel stamping shaft 11, which can restrict the position of the steel stamp sleeve 13 on the steel stamping shaft 11, so that the steel stamp sleeve 13 will not move during the stamping process, ensuring the smooth progress of the stamping operation. In the adjustment state, the limiting member 12 loosens its grip on the steel stamping shaft 11, and the position of the steel stamp sleeve 13 on the steel stamping shaft 11 is adjustable. At this time, the operator can adjust the position between the steel stamp sleeve 13 and the corresponding flexible support sleeve 23 so that the steel stamp on the steel stamp sleeve 13 can always be accurately pressed onto the flexible support sleeve 23, ensuring the accuracy of the stamping position. Compared with existing technologies, it is no longer necessary to disassemble the limiting member 12 and the drive gear set 100 located at the end of the stamping shaft 11, making the operation convenient and quick, reducing adjustment costs and improving adjustment efficiency. The flexible support sleeve 23 is mounted on the second mounting ring 222, which is detachably connected to the first mounting ring 221. When the flexible support sleeve 23 wears, the operator can remove the second mounting ring 222 from the first mounting ring 221 to separate the flexible support sleeve 23 from the pressure shaft 21 for replacement, significantly improving replacement efficiency. Moreover, during replacement, only the second mounting ring 222 and the flexible support sleeve 23 need to be replaced, without replacing the entire pressure roller 2, which helps reduce replacement costs.

[0038] Optionally, see Figure 1Multiple stamping sleeves 13, mounting bases 22, and flexible support sleeves 23 are provided. Multiple stamping sleeves 13 are arranged at intervals along the axial direction of the stamping shaft 11, and multiple flexible support sleeves 23 correspond one-to-one with multiple stamping sleeves 13. This arrangement allows for stamping of multiple brands of cigarette boxes or different positions on cigarette boxes using only one stamping roller system, significantly improving the applicability of the stamping roller system and enhancing the convenience of stamping cigarette boxes.

[0039] For example, see Figure 1 There are two of each of the following: the stamped sleeve 13, the mounting base 22, and the flexible support sleeve 23.

[0040] In this embodiment, see Figure 2 The stamping roller 1 also includes several first separating rings 14 sleeved on the stamping shaft 11, with one first separating ring 14 provided between any two adjacent stamping sleeves 13. The first separating rings 14 can separate two adjacent stamping sleeves 13, preventing collisions between the two stamping sleeves 13 and ensuring the reliability of the stamping.

[0041] In this embodiment, see Figure 3 The pressure roller 2 also includes several second partition rings 24 sleeved on the pressure shaft 21, with one second partition ring 24 provided between any two adjacent mounting seats 22. The second partition rings 24 can separate two adjacent mounting seats 22, preventing collisions between the two mounting seats 22 and ensuring the reliability of the imprinting.

[0042] Optionally, see Figure 2 The limiting member 12 includes a limiting part 121 and a fastening part 122. The limiting part 121 extends circumferentially along the stamping shaft 11. In the use state, the fastening part 122 passes through the first end of the limiting part 121 and is fastened to the second end of the limiting part 121, so that the first end and the second end of the limiting part 121 are tightly connected, thereby the limiting member 12 as a whole can hold the stamping shaft 11 tightly. In the adjustment state, the fastening part 122 is separated from the second end of the limiting part 121, so that the first end and the second end of the limiting part 121 are no longer tightly connected, thereby the limiting member 12 as a whole can loosen the stamping shaft 11.

[0043] The first end and the second end of the limiting part 121 are the two ends of the limiting shaft along its extension direction, respectively.

[0044] For example, see Figure 2 The limiting part 121 is a C-shaped ring.

[0045] Specifically, see Figure 2When the fastening part 122 is fastened to the second end of the limiting part 121, the fastening part 122 connects the first and second ends of the limiting part 121 together, allowing the limiting part 121 to be in close contact with the stamping shaft 11, and the limiting member 12 cannot move on the stamping shaft 11. At this time, the limiting member 12 is in use, and the lower end of the limiting part 121 can contact the stamping sleeve 13, thereby allowing the limiting member 12 to limit the stamping sleeve 13 to the stamping position. When the fastening part 122 is separated from the second end of the limiting part 121, the first end of the limiting part 121 is no longer fastened to the second end of the limiting part 121, the limiting part 121 is no longer in close contact with the stamping shaft 11, and a gap is created between the limiting part 121 and the stamping sleeve 13, thereby allowing the stamping sleeve 13 to move on the stamping shaft 11.

[0046] In this embodiment, the fastening part 122 passes through the first end of the limiting part 121 and is threadedly engaged with the second end of the limiting part 121. This arrangement allows the fastening part 122 to be connected to or separated from the second end of the limiting part 121 simply by tightening the fastening part 122, making the operation convenient and quick; moreover, it also ensures the stability of the connection between the fastening part 122 and the second end of the limiting part 121.

[0047] Specifically, see Figure 2 The first end of the limiting part 121 is provided with a first connecting hole 1211, and the second end of the limiting part 121 is provided with a threaded hole 1212. The fastening part 122 includes a screw rod, which passes through the first connecting hole 1211 and is threadedly engaged with the hole wall of the threaded hole 1212, thereby realizing the threaded connection between the fastening part 122 and the second end of the limiting part 121.

[0048] For example, the fastener 122 is a bolt or screw.

[0049] In an optional embodiment, see [link to relevant documentation] Figure 3 and Figure 4 The second mounting ring 222 has a mounting groove 2221 extending circumferentially therein. The flexible support sleeve 23 is disposed within the mounting groove 2221 and is fixedly connected to the groove wall of the mounting groove 2221. This arrangement allows the second mounting ring 222 to be removed from the first mounting ring 221 when the flexible support sleeve 23 needs to be replaced. The second mounting ring 222 can then drive the flexible support sleeve 23 away from the pressure shaft 21. Subsequently, the second mounting ring 222 and the flexible support sleeve 23 can be replaced together.

[0050] For example, the flexible support sleeve 23 includes a rubber sleeve that is bonded or vulcanized and fixed within the mounting groove 2221.

[0051] In another alternative embodiment, see [link to relevant documentation] Figure 3 and Figure 4The second mounting ring 222 is provided with a mounting groove 2221 extending circumferentially therein, and the flexible support sleeve 23 is engaged in the mounting groove 2221. This arrangement allows the flexible support sleeve 23 to be removed from the mounting groove 2221 and separated from the second mounting ring 222 after the second mounting ring 222 drives the flexible support sleeve 23 to disengage from the pressure shaft 21. Subsequently, a new flexible support sleeve 23 can be installed on the second mounting ring 222, which helps to further reduce the cost of replacing the flexible support sleeve 23.

[0052] Optionally, see Figure 4 The mounting base 22 also includes a fastener 223, which passes through the second mounting ring 222 and is fastened to the first mounting ring 221 to achieve a detachable connection between the first mounting ring 221 and the second mounting ring 222.

[0053] In this embodiment, see Figure 4 The fastener 223 is threadedly connected to the first mounting ring 221. This design not only ensures the stability of the connection between the fastener 223 and the first mounting ring 221, but also makes the connection and separation of the fastener 223 and the first mounting ring 221 more convenient and quick, which helps to improve the efficiency of replacing the flexible support sleeve 23.

[0054] Specifically, the first mounting ring 221 is provided with a connection position 2211, and the connection position 2211 is provided with an internal thread. The fastener 223 is provided with an external thread that mates with the internal thread, so as to realize the threaded connection between the fastener 223 and the first mounting ring 221.

[0055] For example, when the connection position 2211 is a hole, the internal thread is provided on the hole wall; when the connection position 2211 is a connecting groove, the internal thread is provided on the groove wall.

[0056] For example, fastener 223 is a bolt or screw.

[0057] See Figure 4 The second mounting ring 222 is provided with a second connecting hole 2222, and the fastener 223 passes through the second connecting hole 2222 and is threadedly connected to the first mounting ring 221.

[0058] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
