Technical Field
[0001] This utility model relates to the field of cigarette manufacturing, and more specifically, to an improved steel stamping roller for a ZB45 hard-pack packaging machine. Background Technology
[0002] Generally speaking, the ZB45 packaging machine is used to package small hard-pack cigarette packs. The function of the steel stamping roller assembly is to print a clear steel stamp number on the bottom of the hard-pack cigarette pack according to the process quality requirements, and all the steel stamp characters must be neat and consistent in depth.
[0003] The ZB45 hard-pack packaging machine has a packaging speed of 400 packs / minute. During high-speed operation, the stamped serial number on each pack of cigarettes must be clear, neat, and consistent in depth. Due to the high operating speed and long operating time, the stamped serial number will wear into the liner roller, creating grooves of varying depths. Because the original design of the liner roller is keyed to the shaft, the stamped serial number is always pressed into a fixed position on the liner roller, eventually causing grooves and resulting in unclear, inconsistent, or even punctured stamped serial numbers. When these defects occur, the liner roller must be replaced. After replacement, the height of the stamped serial number needs to be readjusted, leading to excessive consumption of spare parts, wasting a lot of time, affecting the effective operating rate of the equipment, and increasing the risk of product quality defects.
[0004] In summary, excessive wear on the working surface of the stamping roller liner can cause quality defects such as unclear stamped characters. At the same time, frequent replacement of the liner roller also leads to excessive consumption of spare parts, and adjusting the position of the stamped characters will waste too much working time, resulting in a decrease in equipment efficiency.
[0005] Therefore, how to provide an improved steel stamping roller for the ZB45 hard box packaging machine has become a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0006] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide an improved steel stamping code liner roller for the ZB45 packaging machine. By using bearings to make the liner roller rotate as a whole, it prevents the same position from being continuously pressed with steel stamping numbers, which would cause wear and grooves to appear on the liner roller after long-term use, resulting in unclear steel stamping numbers, inconsistent steel stamping numbers, or even steel stamping numbers being directly penetrated, thus reducing the risk of product quality defects.
[0007] At the same time, frequent replacement of faulty rollers will also cause excessive wear and tear on spare parts. For example, after replacing the rollers, it is necessary to adjust the height of the stamped characters, which will result in more wasted time and increased equipment maintenance costs.
[0008] Another objective of this invention is to prevent the loosening caused by deformation of the fixed position within the original fixed roller, which would affect printing quality and result in blurry prints, by using a bearing to rotate the entire roller. During the disassembly and replacement of the original roller, dust and moisture entering the threaded holes could cause bolt corrosion and jamming, hindering disassembly. Similarly, jamming could occur between the roller and the fixed shaft. Replacing the roller with a bearing structure avoids these issues, facilitating replacement operations, saving time, and improving the equipment's effective operating rate.
[0009] To solve the above problems and achieve the above-mentioned objectives, this utility model provides an improved steel stamping roller for the ZB45 packaging machine, which is achieved by adopting the following design structure and the following technical solution.
[0010] An improved ZB45 packaging machine steel stamping code roller, including a fixed shaft (3) passing through the steel stamping code roller, is characterized in that it further includes:
[0011] The steel stamp code roller (1) is connected to the fixed shaft (3) through a sleeve.
[0012] Limiting component (2) is located at one end of the steel stamp code roller (1) and is connected to the fixed shaft (3) through a sleeve.
[0013] Among them, rotating components are installed at both ends of the steel stamp code roller (1);
[0014] Both ends of the steel stamping code roller (1) are provided with snap ring grooves and bearing grooves from the outside to the inside;
[0015] The rotating assembly includes:
[0016] The bearing (11) has an inner ring that can be fitted onto the fixed shaft (3), and an outer ring that contacts the bearing grooves at both ends of the steel stamp code roller (1).
[0017] The snap ring (12) is embedded in the snap ring grooves at both ends of the steel stamp code roller (1) and closely adheres to the bearing (11).
[0018] Among them, the bearing (11) and the snap ring (12) are two sets, symmetrically designed;
[0019] The limiting member (2) includes:
[0020] The limiting component body (21) is a hollow columnar structure. There is a protrusion on the surface of the limiting component body (21), and the protrusion is provided with an internal thread hole.
[0021] The limiting screw (22) is used in conjunction with the internal threaded hole on the limiting part body (21).
[0022] Preferably, the length of the external thread section of the limiting screw (22) is greater than the length of the internal thread hole of the limiting part body (21). After the limiting screw (22) is tightened, the limiting part body (21) can be fixed on the fixed shaft (3).
[0023] Preferably, the diameter and thickness of the limiting member body (21) are the same as the diameter and thickness of the inner ring of the bearing (11);
[0024] The protruding part of the limiting member body (21) is used to restrict the lateral movement of the steel stamp code roller (1) and does not affect the rotation of the bearing (11).
[0025] Preferably, the fixed shaft (3) comprises:
[0026] The fixed shaft body (32) has two ring structures of different lengths. One end of the fixed shaft body (32) is fixedly connected to the main body of the equipment (6), and the other end allows the steel stamp code roller (1) and the limiting piece (2) to pass through.
[0027] Washer (31) is fitted onto fixed shaft (3). The diameter and thickness of washer (31) are the same as the inner ring diameter and thickness of bearing (11).
[0028] The working principle is as follows: Before the ZB45 packaging machine steel stamp code roller with the above-mentioned improved design structure is used, the original steel stamp code roller is fixed to the fixed shaft 3 by bolts. Therefore, the process of replacing the steel stamp code roller is as follows: First, loosen and remove the connecting bolts on the steel stamp code roller to be replaced and store it in the fixed position. Then, remove the steel stamp code roller to be replaced. Install bearings (11) and snap rings (12) at both ends of the steel stamp code roller (1). The bearings (11) are located in the bearing grooves at both ends of the steel stamp code roller (1), and the snap rings (12) are located in the snap ring grooves at both ends of the steel stamp code roller (1), fitting with the bearings (11) and fixing the bearings (11) to both ends of the steel stamp code roller (1). Then, insert the washer (31) from one end of the fixed shaft (3) and fit it against the ring structure fixed on the fixed shaft (3). Then, install the bearings (11) and snap rings (12) on the steel stamp code roller (1). Finally, the limiting body (21) is passed through the fixed shaft (3), with the protruding end located at the far end of the steel stamp code roller (1). The limiting body (21) is pushed, and the steel stamp code roller (1) is driven until the bearing (11), washer (31) and the annular structure on the fixed shaft (3) are tightly fitted. Then, the limiting screw (22) is tightened from the threaded hole protruding from the limiting body (21) to fix the limiting part (2) on the fixed shaft (3). The lateral movement of the steel stamp code roller (1) is restricted by the limiting part (2), washer (31) and the annular structure on the fixed shaft. Then, the position of the steel stamp code (4) is adjusted so that the code can fall in the fixed area of the steel stamp code roller (1).
[0029] During use: After the cigarette pack paper (5) from the previous station arrives at the printing station, the cigarette pack paper (5) moves and is conveyed between the steel printing code roller (1) and the steel printing code (4). After the cigarette pack paper (5) reaches the position to be marked, the steel printing code (4) moves downward and prints the code on the fixed position of the cigarette pack paper (5). At this time, the steel printing code roller (1) is driven by the cigarette pack paper (5) and rotates around the fixed shaft (3) through the bearing (11). Each time the steel printing code (4) falls, the force position of the steel printing code roller (1) is not fixed and is different.
[0030] When replacement is required, pause the operation of the cigarette pack paper (5) and the stamped code (4), first loosen the limit screw (22), then remove the limit piece (2) from one end of the fixed shaft (3), and fix the other end of the fixed shaft (3) to the main body of the equipment (6). Then remove the stamped code roller (1) and check whether the bearing (11) or the stamped code roller (1) needs to be replaced. If the bearing (11) needs to be replaced, remove the retaining rings (12) at both ends of the stamped code roller (1), remove the old bearing, replace it with a new bearing, and then repeat the above operation for installation. If the stamped code roller (1) needs to be replaced, take out the new stamped code roller (1) and then perform the above installation operation. This will not be repeated here until all operations are completed.
[0031] Finally, as time goes by, once all the work is completed, operators only need to clean and repair the various components of this invention, and conduct regular maintenance and inspections to ensure its safety and reliability.
[0032] In summary, the beneficial effects of this utility model compared with the prior art are as follows:
[0033] 1. By setting a bearing (11) and a retaining ring (12), the steel stamp code roller (1) can rotate freely on the fixed shaft (3), which avoids the steel stamp code (4) being subjected to a fixed position due to long-term use when the steel stamp code roller (1) is fixed, resulting in severe local wear of the steel stamp code roller (1) and unclear steel stamp code.
[0034] 2. By eliminating the original fixing bolts and replacing them with bearings (11) and limiting parts (2), this utility model avoids the situation where the original threaded structure may rust and jam between the bolts and various parts due to factors such as moisture and dust in the environment during long-term use, making it impossible to disassemble the steel stamp code roller (1). Moreover, it can solve the problem that frequent replacement and adjustment will cause excessive wear of spare parts, waste a lot of time, affect the working rate, and increase the risk of product quality defects.

[0045] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0046] Example 1
[0047] An improved ZB45 packaging machine steel stamping code roller, comprising a fixed shaft 3 passing through the steel stamping code roller, characterized in that: it further comprises:
[0048] Steel stamp code roller 1, steel stamp code roller 1 is connected to fixed shaft 3 through a sleeve;
[0049] Limiting component 2 is located at one end of the steel stamp code roller 1 and is sleeved and connected to the fixed shaft 3.
[0050] Among them, rotating components are installed at both ends of the steel stamp code roller 1;
[0051] Both ends of the steel stamp code roller 1 are provided with snap ring grooves and bearing grooves from the outside to the inside;
[0052] The rotating assembly includes:
[0053] Bearing 11, the inner ring of bearing 11 can be sleeved on fixed shaft 3, and the outer ring is in contact with the bearing grooves at both ends of steel stamp code roller 1;
[0054] Snap ring 12 is embedded in the snap ring grooves at both ends of the steel stamp code roller 1 and is in close contact with the bearing 11;
[0055] Among them, bearing 11 and snap ring 12 are two sets, with a symmetrical design.
[0056] In the ZB45 packaging machine's improved steel stamp code roller design described above, the original steel stamp code roller is fixed to the fixed shaft 3 with bolts. Therefore, the process of replacing the steel stamp code roller is as follows: First, loosen and remove the connecting bolts on the steel stamp code roller to be replaced, store it in the fixed position, and then remove the steel stamp code roller to be replaced. Bearings 11 and retaining rings 12 are installed at both ends of the steel stamp code roller 1. The bearings 11 are located in the bearing grooves at both ends of the steel stamp code roller 1, and the retaining rings 12 are located in the retaining ring grooves at both ends of the steel stamp code roller 1, fitting against the bearings 11, and fixing the bearings 11 to both ends of the steel stamp code roller 1.
[0057] Example 2
[0058] Furthermore, the limiting member 2 includes:
[0059] The limiting component body 21 is a hollow cylindrical structure with a protrusion on its surface and an internal threaded hole on the protrusion.
[0060] Limit screw 22 is used in conjunction with the internal threaded hole on the limit component body 21.
[0061] Furthermore, the length of the external thread section of the limiting screw 22 is greater than the length of the internal thread hole of the limiting component body 21. After the limiting screw 22 is tightened, the limiting component body 21 can be fixed on the fixed shaft 3.
[0062] Furthermore, the diameter and thickness of the limiting member body 21 are the same as the diameter and thickness of the inner ring of the bearing 11;
[0063] The protruding portion of the limiting member body 21 is used to restrict the lateral movement of the steel stamp code roller 1, and does not affect the rotation of the bearing 11.
[0064] In this utility model, the original steel stamp code roller was fixed to the fixed shaft 3 by bolts. After the design was changed to bearing 11 and snap ring 12, the steel stamp code roller 1 lacked a fixing mechanism and would move laterally on the fixed shaft 3. Therefore, the design of the limiting part 2 was added so that the steel stamp code roller 1 could rotate in a fixed position, avoiding repeated adjustment of the steel stamp code 4.
[0065] Example 3
[0066] Furthermore, the fixed shaft 3 includes:
[0067] The fixed shaft body 32 has two ring-shaped structures of different lengths. One end of the fixed shaft body 32 is fixedly connected to the main body 6 of the equipment, and the other end allows the steel stamping code roller 1 and the limiting member 2 to pass through.
[0068] Washer 31 is fitted onto fixed shaft 3. The diameter and thickness of washer 31 are the same as the diameter and thickness of the inner ring of bearing 11.
[0069] In the use of this utility model, after installing the bearing 11 and the retaining ring 12, the washer 31 is inserted from one end of the fixed shaft 3 and fitted against the annular structure fixed on the fixed shaft 3. The steel stamp code roller 1 is then fitted with the bearing 11 and the retaining ring 12. Finally, the limiting member body 21 is passed through the fixed shaft 3, with its protruding end located at the far end of the steel stamp code roller 1. The limiting member body 21 is pushed, moving the steel stamp code roller 1 until the bearing 11, the washer 31, and the annular structure on the fixed shaft 3 are tightly fitted. The limiting screw 22 is then tightened from the threaded hole protruding from the limiting member body 21, fixing the limiting member 2 to the fixed shaft 3. The lateral movement of the steel stamp code roller 1 is restricted by the limiting member 2, the washer 31, and the annular structure on the fixed shaft. Then, the position of the steel stamp code 4 is adjusted so that the code falls within the fixed area of the steel stamp code roller 1.
[0070] In this utility model, the design of the washer 31 can effectively prevent the annular structure on the fixed shaft 3 from affecting the rotation of the bearing 11 when the steel stamp code roller 1 rotates on the fixed shaft 3. By setting a washer 31 with the same diameter and thickness as the inner ring diameter and thickness of the bearing 11, the inner ring of the bearing is fixed, and the outer ring will not be affected by other components during rotation, thus ensuring smooth rotation.
[0071] In summary, a more specific embodiment of this utility model is as follows:
[0072] like Figure 1 As shown, an improved ZB45 packaging machine steel stamping code roller includes a steel stamping code roller 1, a limiting component 2, a fixed shaft 3, steel stamping code 4, cigarette pack paper 5, and the main body of the equipment 6.
[0073] Before use: The original steel stamp code roller is fixed to the fixed shaft 3 with bolts. Therefore, the process of replacing the steel stamp code roller is as follows: First, loosen and remove the connecting bolts on the steel stamp code roller to be replaced and store it in the fixed position. Remove the steel stamp code roller to be replaced. Install bearings 11 and retaining rings 12 at both ends of the steel stamp code roller 1. The bearings 11 are located in the bearing grooves at both ends of the steel stamp code roller 1, and the retaining rings 12 are located in the retaining ring grooves at both ends of the steel stamp code roller 1, fitting against the bearings 11, and fix the bearings 11 to both ends of the steel stamp code roller 1. Then, insert the washer 31 from one end of the fixed shaft 3 and fit it against the annular structure fixed on the fixed shaft 3. Then, install the steel stamp code roller 1 with the bearings 11 and retaining rings 12. Finally, the limiting component body 21 is passed through the fixed shaft 3, with the protruding end located at the far end of the steel stamp code roller 1. The limiting component body 21 is pushed, driving the steel stamp code roller 1 until the bearing 11, washer 31 and the annular structure on the fixed shaft 3 are tightly fitted. The limiting screw 22 is then tightened from the threaded hole protruding from the limiting component body 21 to fix the limiting component 2 on the fixed shaft 3. The lateral movement of the steel stamp code roller 1 is restricted by the limiting component 2, washer 31 and the annular structure on the fixed shaft. Then the position of the steel stamp code 4 is adjusted so that the code can fall in the fixed area of the steel stamp code roller 1.
[0074] During use: After the cigarette pack paper 5 from the previous station arrives at the printing station, the cigarette pack paper 5 moves and is conveyed between the steel printing code roller 1 and the steel printing code 4. After the cigarette pack paper 5 reaches the position to be marked, the steel printing code 4 moves downward and prints the code on the fixed position of the cigarette pack paper 5. At this time, the steel printing code roller 1 is driven by the cigarette pack paper 5 and rotates around the fixed shaft 3 through the bearing 11. Each time the steel printing code 4 falls, the force position of the steel printing code roller 1 is not fixed and is different.
[0075] When replacement is needed, pause the operation of the cigarette pack paper 5 and the stamped code 4. First, loosen the limit screw 22, then remove the limit piece 2 from one end of the fixed shaft 3. The other end of the fixed shaft 3 is fixedly connected to the main body 6 of the equipment. Then, remove the stamped code roller 1 and check whether the bearing 11 or the stamped code roller 1 needs to be replaced. If the bearing 11 needs to be replaced, remove the retaining springs 12 at both ends of the stamped code roller 1, remove the old bearing, replace it with a new bearing, and then repeat the above operation for installation. If the stamped code roller 1 needs to be replaced, remove the new stamped code roller 1 and then perform the above installation operation, which will not be repeated here.
[0076] Finally, as time goes by, once all the work is completed, operators only need to clean and repair the various components of this invention, and conduct regular maintenance and inspections to ensure its safety and reliability.
[0077] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit connection, or a plug-in structure connection.
[0078] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments.
