Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a cutting adjustment fixture for a cigarette machine paper feeder. Background Technology

[0002] In modern automated tobacco production systems, the efficient and stable operation of cigarette rolling machines is crucial for ensuring both product quality and production efficiency. For example, the ZJ112 cigarette rolling machine, a widely used mainstream model in the industry, boasts a high degree of automation and fast production speed, playing a core role in the cigarette production process. The automated production line operation of the ZJ112 is interconnected, from the conveying of cigarette paper and the filling and rolling of tobacco shreds to the forming and cutting of cigarettes. Any deviation in any link can affect the final cigarette quality. Among these components, the SE paper feeder, as the core actuator for the continuous supply of cigarette paper in the ZJ112 cigarette rolling machine, plays a vital role. During the continuous supply of cigarette paper, when a roll of cigarette paper is about to run out and needs to be replaced with new paper, the cutter of the SE paper feeder needs to precisely and quickly cut the old cigarette paper and connect it with the new paper to ensure uninterrupted cigarette production. The cutting accuracy, angle, and coordination of the cutter of the SE paper feeder directly determine the success rate and production continuity of the cigarette paper changing process. If the cutter is not properly adjusted, problems such as uneven cigarette paper cuts and failed paper changing leading to equipment downtime may occur, which not only reduces production efficiency but may also cause a chain reaction such as cigarette appearance defects and material waste.

[0003] However, the existing method of adjusting the cutter of the paper feeder in cigarette machines mainly relies on manual operation. Operators need to adjust the position, angle and other parameters of the cutter based on their experience. This adjustment method is highly dependent on the operator's skills and experience. During the adjustment process, the position and angle of the cutter need to be adjusted continuously, and the position and angle of the cutter need to be judged by manual visual inspection to see if they meet the technical requirements for the cutter. This is not only inefficient, but also prone to human error, affecting the adjustment accuracy.

[0004] Therefore, the existing methods for adjusting the cutter of the paper feeder in cigarette machines have technical problems such as complex operation and limited adjustment accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cutting adjustment fixture for a cigarette machine paper feeder, so as to solve the technical problems of complex operation and limited adjustment accuracy of the existing cutting adjustment method for cigarette machine paper feeders.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A cutting adjustment fixture for a cigarette machine paper feeder, the cigarette machine paper feeder including a rear cutter, a loop roller, a front cutter, a tape holder, and a guide roller, the cutting adjustment fixture for the cigarette machine paper feeder includes: a front cutter adjustment fixture for adjusting the gap between the blade of the front cutter and the tape holder, the front cutter adjustment fixture including a U-shaped structural component, the U-shaped structural component including two parallel side plates, the thickness of at least one side plate being a first preset value, the first preset value being the gap between the blade of the front cutter and the tape holder as specified by the blade alignment technical requirements of the front cutter; and a rear cutter adjustment fixture for adjusting the gap between the blade of the rear cutter and the guide roller, the rear cutter adjustment fixture including a semi-cylindrical structural component and an L-shaped positioning block, the two sides of the semi-cylindrical structural component being provided with first vertical extensions. The semi-cylindrical structure has a second vertical extension and a second vertical extension. The thickness of the semi-cylindrical structure is a second preset value, which is the gap between the blade of the rear cutter and the guide roller as specified in the back cutter's blade setting technical requirements. When setting the front cutter, the tape holder is placed between the two side plates of the U-shaped structure to mount the U-shaped structure on the tape holder. When setting the rear cutter, the L-shaped positioning block is fixedly installed above the guide roller, and the L-shaped positioning block is located on a vertical surface passing through the center line of the guide roller. The semi-cylindrical structure is mounted on the guide roller, and the inner wall of the semi-cylindrical structure is tightly fitted to the outer side of the guide roller. The first vertical extension is tightly fitted and fixedly connected to the L-shaped positioning block, and the outer side of the second vertical extension is located on a vertical surface passing through the center line of the guide roller.

[0008] The beneficial technical effects of this utility model are as follows: The above-mentioned cutting blade adjustment fixture for the cigarette machine paper receiver includes a front cutting blade adjustment fixture and a rear cutting blade adjustment fixture. The front cutting blade adjustment fixture includes a U-shaped structural component, and the rear cutting blade adjustment fixture includes a semi-cylindrical structural component and an L-shaped positioning block. When the front cutting blade needs to be aligned, the U-shaped structural component is installed on the tape holder. During alignment, the U-shaped structural component is used as an alignment guide; simply placing the blade of the front cutting blade against the surface of the U-shaped structural component completes the alignment, eliminating the error of manual visual judgment. This invention enables rapid and standardized adjustment of the gap between the front cutter blade and the tape holder. When the rear cutter needs to be aligned, the semi-cylindrical structure is mounted on the guide roller via the L-shaped positioning block and pressed tightly against the guide roller. During alignment, the rear cutter blade only needs to be placed against the connection between the semi-cylindrical structure and the second vertical extension below it. The combined positioning of the L-shaped positioning block and the semi-cylindrical structure during alignment eliminates reliance on experience, achieving automatic locking through a mechanical structure, significantly improving alignment accuracy and efficiency. In summary, this invention provides a cutting adjustment fixture for cigarette machine paper feeders, enabling rapid, convenient, and precise alignment of the front and rear cutters. It achieves efficient calibration of the front and rear cutter parameters, is easy to operate, and solves the technical problems of complex operation and limited adjustment accuracy in existing cigarette machine paper feeder cutting adjustment methods.

[0018] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2 As shown, the cigarette machine paper feeder includes a rear cutter 1, a loop roller 2, a front cutter 3, a tape holder 4 for bonding cigarette paper, a negative pressure suction device 5, a moving bracket 6, and a guide roller 7 for rotating the cigarette paper. The cigarette machine paper feeder is used to bond the nearly used cigarette paper roll to the new roll. After bonding, the remaining paper roll and the starting paper roll of the new roll are cut off. The entire paper feeding process is as follows: when the nearly used roll reaches the set residual diameter, the acceleration function of the new roll is triggered; when the paper roll speeds on both sides reach the same, the bonding action begins; simultaneously, the front cutter 3 cuts the remaining roll, and the negative pressure suction device 5 sucks away the cut paper; the tape holder 4 releases and rotates out from the bonding position, the loop roller 2 releases, and the rear cutter 1 cuts off the starting paper roll of the new roll at the joint, thus completing the entire paper feeding process.

[0020] To ensure the success rate and production continuity of the cigarette paper replacement process, the position, angle, pressure, and other parameters of the front cutter 3 and rear cutter 1 of the cigarette machine paper receiver need to be adjusted before cigarette production begins. To achieve efficient calibration of the parameters of the front cutter 3 and rear cutter 1 of the cigarette machine paper receiver, this invention provides a cutter adjustment fixture for the cigarette machine paper receiver, including a front cutter adjustment fixture and a rear cutter adjustment fixture. The front cutter adjustment fixture is used to adjust the gap between the blade of the front cutter 3 and the tape holder 4, and the rear cutter adjustment fixture is used to adjust the gap between the blade of the rear cutter 1 and the guide roller 7.

[0021] like Figure 4 As shown, the front cutter adjustment fixture includes a U-shaped structural component 10, which includes a first side plate 11 and a second side plate 12, which are parallel to each other. The U-shaped structural component 10 is made of tool steel or other hardware materials.

[0022] like Figure 5As shown, in a preferred embodiment of this utility model, the thickness of the first side plate 11 of the U-shaped structural member 10 is d1, the thickness of the second side plate 12 is d2, and d1 > d2. To meet the blade setting requirements of the front cutter 3, d1 is set to a first preset value, which is the gap between the blade of the front cutter 3 and the tape holder 4 as specified in the blade setting requirements. For example, if the blade setting requirements of the front cutter 3 are: the gap B between the blade of the front cutter 3 and the tape holder 4 is 3mm ± 0.1mm, and it is parallel to the tape holder 4; then, the value of d1 is d1 = 3mm ± 0.1mm. Those skilled in the art will understand that the thickness d1 of the first side plate 11 can be adjusted accordingly based on the different blade setting requirements of the front cutter 3. In this embodiment, with the thickness of the first side plate 11 being a first preset value, the thickness of the second side plate 12 is designed to be less than the first preset value, that is, less than the thickness of the first side plate 11. This makes the U-shaped structural component 10 lighter and saves materials.

[0023] like Figure 3 As shown, when the front cutter 3 needs to be aligned, the tape holder 4 is first placed between the two side plates of the U-shaped structural member 10 and the U-shaped structural member 10 is installed on the tape holder 4, and the first side plate 11 is placed on the top surface of the tape holder 4; then the tape holder 4 is rotated to the bonding position, and the front cutter 3 is aligned; when aligning, the U-shaped structural member 10 is used as the alignment gauge. The blade of the front cutter 3 is simply attached to the first side plate 11 of the U-shaped structural member 10 to ensure that the gap between the blade of the front cutter 3 and the tape holder 4 meets the design standard, eliminating the error of manual visual judgment and realizing the rapid and standardized adjustment of the gap between the blade of the front cutter 3 and the tape holder 4.

[0024] To allow the tape holder 4 to be inserted between the two side plates of the U-shaped structural member 10 and mounted on the tape holder 4, this invention designs the distance between the first side plate 11 and the second side plate 12 of the U-shaped structural member 10 to be greater than or equal to the thickness of the tape holder 4. Specifically, to ensure the tape holder 4 can be inserted between the two side plates of the U-shaped structural member 10, the distance between the first side plate 11 and the second side plate 12 is at least the thickness of the tape holder 4; and since, after the U-shaped structural member 10 is mounted on the tape holder 4, one side plate of the U-shaped structural member 10 lies flat on the top surface of the tape holder 4, therefore, the distance between the first side plate 11 and the second side plate 12 can be greater than the thickness of the tape holder 4.

[0025] like Figure 3As shown, the tape holder 4 is rotatably connected to the cigarette machine paper receiver via a rotating shaft 8. The tape holder 4 can be rotated to or away from the bonding position. When installing the U-shaped structural component 10, the tape holder 4 can be rotated away from the bonding position to facilitate the installation of the U-shaped structural component 10. After installing the U-shaped structural component 10 on the tape holder 4, the tape holder 4 can be rotated to the bonding position to begin the blade alignment operation of the front cutter 3.

[0026] In other embodiments of this utility model, the first side plate 11 and the second side plate 12 of the U-shaped structural member 10 can have the same thickness, that is, the thickness of the first side plate 11 and the second side plate 12 is designed to a first preset value, so as to achieve the symmetrical design of the U-shaped structural member 10. The first side plate 11 and the second side plate 12 can both be used to assist in completing the cutting operation of the front cutter 3, which can avoid the failure of cutting due to misalignment of the two side plates of the U-shaped structural member 10. Alternatively, the thickness d1 of the first side plate 11 of the U-shaped structural member 10 can be designed to a first preset value, and the thickness d2 of the second side plate 12 can be designed to be d2 > d1.

[0027] like Figure 6 As shown, the rear cutter adjustment fixture includes a semi-cylindrical structure 20 and an L-shaped positioning block 30. The L-shaped positioning block 30 and the semi-cylindrical structure 20 are made of tool steel or other hardware materials. Figure 7 As shown, the semi-cylindrical structure 20 has a first vertical extension 21 and a second vertical extension 22 on both sides, and the thickness of the first vertical extension 21 and the second vertical extension 22 is the same as the thickness of the semi-cylindrical structure 20.

[0028] like Figure 8 As shown, the thickness of the semi-cylindrical structure 20 is d3. To meet the tool setting requirements of the rear cutter 1, d3 is set to a second preset value, which is the gap between the blade of the rear cutter 1 and the guide roller 7 as specified in the tool setting requirements. For example, when the tool setting requirements of the rear cutter 1 are: the gap C between the rear cutter 1 on the moving bracket 6 and the guide roller 7 is 2.5mm ± 0.1mm, and the blade of the rear cutter 1 is parallel to the vertical plane passing through the center line of the guide roller 7 and located directly below the center line of the guide roller 7; then, the value of d3 is d3 = 2.5mm ± 0.1mm. Those skilled in the art will understand that the thickness d3 of the semi-cylindrical structure 20 can be adjusted accordingly based on the different tool setting requirements of the rear cutter 1.

[0029] like Figure 6As shown, when the rear cutter 1 needs to be set, the L-shaped positioning block 30 is first fixedly installed above the guide roller 7, and the L-shaped positioning block 30 is located on a vertical surface passing through the center line of the guide roller 7; then, the semi-cylindrical structure 20 is installed on the guide roller 7 by tightly fitting and fixing the first vertical extension 21 to the L-shaped positioning block 30. At this time, the inner wall of the semi-cylindrical structure 20 is tightly fitted to the outer side of the guide roller 7, and the outer side of the second vertical extension 22 is located on a vertical surface passing through the center line of the guide roller 7; finally, the blade of the rear cutter 1 is placed at the connection between the semi-cylindrical structure 20 and the second vertical extension 22 to complete the setting. During the setting process, the combination positioning of the L-shaped positioning block 30 and the semi-cylindrical structure 20 makes the setting process of the rear cutter no longer dependent on experience, but is automatically locked by the mechanical structure, which greatly improves the accuracy and efficiency of the setting process.

[0030] like Figure 8 As shown, the distance between the plane containing the inner side of the first vertical extension 21 (near the L-shaped positioning block) and the plane containing the outer side of the second vertical extension 22 is d4. During the back cutter 1's blade alignment, to ensure that the outer side of the second vertical extension 22 is located on a vertical plane passing through the centerline of the guide roller 7, the value of d4 needs to be designed to be half the thickness of the L-shaped positioning block 30.

[0031] like Figure 6 , Figure 7 , Figure 9 As shown, in some preferred embodiments of this utility model, a gap 41 is provided on the mounting bracket 40 of the guide roller 7. The L-shaped positioning block 30 includes a connecting part 31 connected to the first vertical extension 21 and a fixing part 32 perpendicularly connected to the connecting part 31. The fixing part 32 of the L-shaped positioning block 30 is inserted into the gap 41 to fix the L-shaped positioning block 30 above the guide roller 7. A through hole 33 is provided on the connecting part 31, and a threaded hole 211 is provided on the first vertical extension 21 corresponding to the through hole 33. A screw passes through the through hole 33 and is threaded into the threaded hole 211 to achieve a fixed connection between the first vertical extension 21 and the L-shaped positioning block 30.

[0032] This utility model provides a cutting blade adjustment fixture for a cigarette machine paper feeder, including a front cutting blade adjustment fixture and a rear cutting blade adjustment fixture. The front cutting blade adjustment fixture includes a U-shaped structural component, and the rear cutting blade adjustment fixture includes a semi-cylindrical structural component and an L-shaped positioning block. When the front cutting blade of the cigarette machine paper feeder needs to be aligned, the U-shaped structural component is installed on the tape holder. During alignment, the U-shaped structural component serves as an alignment guide; simply placing the blade edge of the front cutting blade against the surface of the U-shaped structural component completes the alignment, eliminating errors from manual visual judgment and achieving precise alignment of the front cutting blade. The invention enables rapid and standardized adjustment of the gap between the blade and the tape holder. When the rear cutter of the cigarette machine paper feeder needs to be aligned, the semi-cylindrical structure is mounted on the guide roller via the L-shaped positioning block and closely adheres to the guide roller. During alignment, the blade of the rear cutter is simply placed against the connection between the semi-cylindrical structure and the second vertical extension below it. The combined positioning of the L-shaped positioning block and the semi-cylindrical structure during alignment eliminates reliance on experience, achieving automatic locking through a mechanical structure, significantly improving alignment accuracy and efficiency. In summary, this invention provides a cutting adjustment fixture for the cigarette machine paper feeder, enabling rapid, convenient, and precise alignment of the front and rear cutters. It achieves efficient calibration of the front and rear cutter parameters, is easy to operate, and solves the technical problems of complex operation and limited adjustment accuracy in existing cigarette machine paper feeder cutting adjustment methods.

All equivalent changes or modifications made within the scope of the claims should fall within the protection scope of the present utility model.
