Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, and in particular to a 15-step baffle calibration fixture. Background Technology

[0002] In the cigarette packaging production process, the fifteen-step station is a critical node for the transfer and conveying of label paper. The label paper output from the fifteen-step station needs to be accurately transferred to the longitudinal conveyor channel, and then conveyed to the subsequent packaging station. The accuracy of the label paper transfer directly determines the packaging quality and production continuity of the cigarette packs. The fifteen-step station is equipped with a first baffle and a second baffle on both sides, extending in the front-to-back direction and spaced apart in the left-to-right direction. Their symmetrical center lines must coincide with the symmetrical center lines of the guide rails of the longitudinal conveyor channel. If there is a deviation between the two center lines, the label paper is prone to offset, skew, misalignment, and jamming during the transfer process. This not only wastes the label paper but also reduces the operating efficiency of the cigarette packaging machine and increases manual adjustment costs.

[0003] Currently, because the baseline for debugging is only a virtual line and cannot be used for measurement and positioning, and because the label paper is enclosed in a metal shell and cannot be observed during transport, adjustments can only be made based on the operator's own experience. This involves repeated debugging and repeated machine start-up verification, which increases the operator's workload, makes the operation cumbersome, and makes it difficult to guarantee accuracy. The debugging time is long, which reduces the efficiency of the cigarette packaging machine, frequently causes label paper edge opening quality problems, creates hidden quality issues, increases the scrap rate, and wastes raw and auxiliary materials.

[0004] Therefore, a fifteen-step workstation baffle calibration fixture is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a 15-step baffle calibration fixture, which eliminates the need for operators to repeatedly debug and verify the machine based on experience, shortens the debugging time, ensures accurate positioning of the label paper conveying, reduces potential quality problems, lowers the scrap rate, and reduces the waste of raw and auxiliary materials.

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

[0007] A 15-step station baffle calibration fixture is used to adjust the first and second baffles on both sides of the 15-step station in a cigarette packaging machine. The first and second baffles are spaced apart in the left-right direction and extend in the front-back direction. The guide rail of the longitudinal conveying channel in the cigarette packaging machine is located downstream of the 15-step station and extends in the front-back direction. After adjustment, the center line of symmetry of the first and second baffles coincides with the center line of symmetry of the guide rail in the front-back direction. The 15-step station baffle calibration fixture includes:

[0008] A rectangular substrate extends along the front-back direction, with its two ends along its length being a positioning end and a mounting end, respectively.

[0009] A positioning insert is fixed to the lower side of the positioning end. Along the front-back direction, the center line of the positioning insert is collinear with the center line of the rectangular substrate. The positioning insert is adapted to and can extend into the gap between the first baffle and the second baffle.

[0010] A positioning support block is fixed to the lower side of the mounting end. After the guide rail is removed, the positioning support block can be adapted to and fixedly installed in the original mounting position of the guide rail.

[0011] Adjust the first baffle and the second baffle so that the opposite sidewalls of the first baffle and the second baffle are respectively in contact with the two sidewalls of the positioning insert plate, so as to calibrate the position of the first baffle and the second baffle.

[0012] As an optional solution for a 15-step baffle calibration fixture, the lower surface of the positioning plate is coplanar with the lower surface of the positioning end of the rectangular substrate along the vertical direction.

[0013] As an optional solution for a 15-step baffle calibration fixture, the width of the positioning plate is adapted to the gap width between the first baffle and the second baffle along the left-right direction.

[0014] As an optional solution for a 15-step station baffle calibration fixture, the length of the positioning plate is greater than or equal to the length of the first baffle and greater than or equal to the length of the second baffle along the front-back direction.

[0015] As an optional solution for a 15-step station baffle calibration fixture, the width of the rectangular base plate is smaller than the width of the positioning insert plate in the left-right direction; and the length of the rectangular base plate is adapted to the total length of the 15-step station and the longitudinal conveying channel in the front-back direction.

[0016] As an optional solution for a 15-step baffle calibration fixture, the 15-step baffle calibration fixture includes two positioning support blocks, which are fixedly mounted at intervals along the front-back direction on the lower surface of the mounting end of the rectangular substrate.

[0017] As an optional solution for a 15-step station baffle calibration fixture, the original mounting position of the guide rail is provided with two threaded holes spaced apart along the center line of the guide rail; the 15-step station baffle calibration fixture also includes two fasteners, each of the two positioning support blocks is provided with a first mounting hole that matches the corresponding threaded hole, and the rectangular base plate is provided with a second mounting hole that is coaxial with the first mounting hole. Both fasteners can pass through the corresponding first mounting hole and the second mounting hole and be threadedly connected to the corresponding threaded hole to fix the relative position of the two positioning support blocks and the cigarette packaging machine.

[0018] As an optional solution for a 15-step station baffle calibration fixture, the height of the positioning support block is consistent with the installation height of the guide rail in the vertical direction. After the two positioning support blocks are fixed, the rectangular base plate is parallel to the conveying reference plane of the cigarette packaging machine.

[0019] As an optional solution for a 15-step station baffle calibration fixture, the positioning insert is provided with scale lines distributed along the length of the positioning insert. The zero mark of the scale line is aligned with the end of the positioning insert that is away from the positioning support block.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-3As shown, this embodiment provides a 15-step station baffle calibration fixture, which is used to adjust the first baffle and the second baffle on both sides of the 15-step station in a cigarette packaging machine. The first baffle and the second baffle are spaced apart in the left-right direction and both extend in the front-back direction. The guide rail of the longitudinal conveying channel in the cigarette packaging machine is located downstream of the 15-step station and extends in the front-back direction. After adjustment, the center line of symmetry of the first baffle and the second baffle coincides with the center line of symmetry of the guide rail in the front-back direction. The 15-step baffle calibration fixture includes a rectangular base plate 1, a positioning insert plate 2, and a positioning support block 3. The rectangular base plate 1 extends in the front-to-back direction, with its two ends along its length being a positioning end and a mounting end, respectively. The positioning insert plate 2 is fixed to the lower side of the positioning end. In the front-to-back direction, the center line of symmetry of the positioning insert plate 2 is collinear with the center line of symmetry of the rectangular base plate 1. The positioning insert plate 2 is adapted to and can extend into the gap between the first baffle and the second baffle. The positioning support block 3 is fixed to the lower side of the mounting end. After the guide rail is removed, the positioning support block 3 is adapted to and can be fixedly installed in the original mounting position of the guide rail. The first baffle and the second baffle are adjusted so that the opposite sidewalls of the first baffle and the second baffle are respectively in contact with the two sidewalls of the positioning insert plate 2 to calibrate the positions of the first baffle and the second baffle.

[0033] When using this 15-step station baffle calibration fixture, insert the positioning plate 2 into the gap between the first and second baffles, fix the positioning support block 3 in its original installation position on the guide rail, and adjust the first and second baffles so that their opposite sidewalls are in contact with the side walls of the positioning plate 2. This will make the symmetrical center lines of the first and second baffles coincide with the symmetrical center lines of the guide rail. This 15-step station baffle calibration fixture eliminates the need for operators to repeatedly debug and verify based on experience, significantly reducing the labor intensity of operators, shortening debugging time, improving the efficiency of cigarette packaging machines, ensuring accurate positioning of label paper feeding, effectively avoiding quality problems such as label paper edge cracking, surface uncleanliness, and misaligned steel stamps, reducing potential quality risks, improving the quality of subsequent cigarette box packaging, reducing scrap rates, and reducing waste of raw and auxiliary materials.

[0034] It is worth noting that the average debugging time based on the operator's own experience is 34 minutes, while the average debugging time using the 15-step station baffle calibration fixture is 3 minutes. Moreover, it can accurately complete the positioning adjustment of the starting end of the longitudinal conveying of the label paper in the front-back direction in one go without placing the label paper, achieving zero debugging consumption and greatly shortening the debugging time.

[0035] like Figure 3 As shown, along the vertical direction, the lower surface of the positioning plate 2 is coplanar with the lower surface of the positioning end of the rectangular substrate 1. This ensures that the positioning plate 2 is inserted smoothly into the gap between the first and second baffles, avoiding jamming or positioning misalignment of the positioning plate 2 due to surface height differences, and further ensuring the reliability of the calibration of the first and second baffles.

[0036] like Figures 1-2 As shown, the width of the positioning plate 2 is matched with the gap width between the first and second baffles along the left-right direction. With fine-tuning, the opposite sidewalls of the first and second baffles can be precisely fitted with the two sidewalls of the positioning plate 2, greatly simplifying the calibration process, reducing the frequency of repeated adjustments, and quickly ensuring that the symmetrical center lines of the first and second baffles coincide with the symmetrical center lines of the guide rail. This effectively avoids quality defects in the label paper feeding caused by positioning deviations, improving calibration efficiency and reliability.

[0037] like Figures 1-3 As shown, along the front-to-back direction, the length of the positioning plate 2 is greater than or equal to the length of the first baffle, and greater than or equal to the length of the second baffle. This ensures that the positioning plate 2 completely covers the extension range of the first and second baffles in the front-to-back direction, guaranteeing that the opposite sidewalls of the first and second baffles precisely fit with the two sidewalls of the positioning plate 2, avoiding local positioning deviations, and further improving calibration accuracy and stability.

[0038] like Figures 1-3 As shown, along the left-right direction, the width of the rectangular base plate 1 is smaller than the width of the positioning insert 2; along the front-back direction, the length of the rectangular base plate 1 is adapted to the total length of the fifteen-step station and the longitudinal conveying channel. On the one hand, the width of the rectangular base plate 1 being smaller than the width of the positioning insert 2 along the left-right direction can avoid interference between the rectangular base plate 1 and the first baffle and the second baffle, ensuring that the positioning insert 2 can smoothly extend into the gap; on the other hand, the length of the rectangular base plate 1 being adapted to the total length of the fifteen-step station and the longitudinal conveying channel along the front-back direction can cover the entire calibration range, ensuring the continuity and uniformity of the positioning reference, and improving the accuracy of the position calibration of the first baffle and the second baffle.

[0039] like Figures 1-3 As shown, the fifteen-step baffle calibration fixture includes two positioning support blocks 3, which are fixedly mounted on the lower surface of the mounting end of the rectangular substrate 1 at intervals along the front-back direction. The two positioning support blocks 3, fixedly mounted on the lower surface of the mounting end of the rectangular substrate 1 at intervals along the front-back direction, provide dual-point stable support for the rectangular substrate 1, ensuring the stability of the positioning insert 2's posture, enhancing the reliability of the overall positioning reference, and improving the accuracy of the alignment of the symmetrical center lines of the first and second baffles with the symmetrical center lines of the guide rail.

[0040] like Figures 1-2As shown, the original mounting position of the guide rail has two threaded holes spaced apart along the center line of the guide rail; the fifteen-step station baffle calibration fixture also includes two fasteners. Each of the two positioning support blocks 3 has a first mounting hole 31 that matches the corresponding threaded hole, and the rectangular base plate 1 has a second mounting hole 11 coaxial with the first mounting hole 31. Both fasteners can pass through the corresponding first mounting hole 31 and second mounting hole 11 and be threadedly connected to the corresponding threaded hole to fix the relative position of the two positioning support blocks 3 and the cigarette packaging machine. The two fasteners passing through the corresponding first mounting hole 31 and second mounting hole 11 and being threadedly connected to the threaded hole at the original mounting position of the guide rail enable a detachable and fixed connection between the two positioning support blocks 3 and the cigarette packaging machine, thereby fixing the overall relative position of the fifteen-step station baffle calibration fixture and the cigarette packaging machine, preventing displacement during calibration, ensuring the stability and reliability of the positioning reference, and the double-point threaded connection structure further improves assembly accuracy, ensuring the accurate positioning of the first and second baffles after calibration.

[0041] like Figure 3 As shown, along the vertical direction, the height of the positioning support block 3 is consistent with the installation height of the guide rail. After the two positioning support blocks 3 are fixed, the rectangular base plate 1 is parallel to the conveying reference plane of the cigarette packaging machine. This ensures that the insertion posture of the positioning insert 2 is horizontal, avoiding uneven contact between the positioning insert 2 and the first and second baffles due to the tilt of the rectangular base plate 1. It also ensures the accuracy of the alignment between the symmetrical center lines of the first and second baffles and the symmetrical center line of the guide rail, improving the stability and reliability of the calibration operation.

[0042] In this embodiment, the positioning insert 2 is provided with scale lines distributed along its length. The zero mark of the scale lines is aligned with the end of the positioning insert 2 opposite to the positioning support block 3. The scale lines are used to measure the depth to which the positioning insert 2 extends between the first and second baffles. This facilitates quick reading of the insertion value and allows for precise control of the insertion position of the positioning insert 2. Combined with the stable positioning of the positioning support block 3, this ensures consistent insertion depth for each adjustment, avoiding deviations in insertion depth that could affect calibration accuracy. This further improves the accuracy and repeatability of adjusting the positions of the first and second baffles.

[0043] In this embodiment, the rectangular base plate 1, the positioning insert plate 2, and the positioning support block 3 are integrally formed. This eliminates positioning errors caused by assembly gaps between components, ensures that the symmetrical center lines of the three components are always collinear along the front-back direction, improves the rigidity and stability of the overall structure, avoids component loosening or deformation during long-term use, ensures long-term stable calibration accuracy, and simplifies the processing and use of the tooling.

[0044] In summary, the steps for calibrating the positions of the first and second baffles using the fifteen-step baffle calibration fixture are roughly as follows:

[0045] First, stop the cigarette packaging machine, keep the first and second baffles stationary, and remove the guide rails of the longitudinal conveyor channel;

[0046] Next, the positioning insert 2 of the fifteen-step station baffle calibration fixture is inserted into the gap between the first baffle and the second baffle, and the two fasteners are respectively inserted through the corresponding first mounting hole 31 and second mounting hole 11 and threadedly connected to the corresponding threaded hole to fix the relative position of the two positioning support blocks 3 and the cigarette packaging machine, thereby fixing the relative position of the entire fifteen-step station baffle calibration fixture and the cigarette packaging machine.

[0047] Next, loosen the first fixing nut of the first baffle, push the first baffle to fit against one side wall of the positioning plate 2, adjust it, and then tighten the first fixing nut to fix the position of the first baffle; loosen the second fixing nut of the second baffle, push the second baffle to fit against the other side wall of the positioning plate 2, adjust it, and then tighten the second fixing nut to fix the position of the second baffle.

[0048] Finally, remove the two fasteners, disassemble the fifteen-step station baffle calibration fixture, reinstall the guide rail, and the position calibration of the first and second baffles of the fifteen-step station is completed, ensuring that the positioning accuracy error is within 0.1 mm.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
