Technical Field

[0001] This utility model relates to the field of tobacco manufacturing equipment maintenance technology, and in particular to a positioning device for a cigarette machine leveler. Background Technology

[0002] like Figure 1 As shown, the leveling device 100 of the dual-channel high-speed cigarette rolling machine includes a first leveling device 101 and a second leveling device 102. The first leveling device 101 and the second leveling device 102 have a V-shaped structure design, respectively adjusting the tobacco in the front and rear flues. The first leveling plate 1011 of the first leveling device 101 is mounted outwardly on the first drive shaft 1012, and the second leveling plate 1021 of the second leveling device 102 is mounted inwardly on the second drive shaft 1022. The leveling device 100 can be disassembled for replacement or repair. After repair and reinstallation, the leveling device 100 needs to be repositioned to ensure that the heights of the first leveling plate 1011 and the second leveling plate 1021 are consistent. Furthermore, after the cigarette rolling machine is installed and debugged, it must be ensured that the center of the leveling device 100 does not shift relative to the center of the tobacco suction guide rail.

[0003] Because the first leveling plate 1011 and the second leveling plate 1021 are tilted, when measuring the height of the first leveling plate 1011 and the second leveling plate 1021, the measuring ruler cannot find a stable reference point and support point, and may tilt inward or outward or left or right, resulting in a large measurement error and inaccurate measurement results. Moreover, it is impossible to measure whether the center of the leveling instrument 100 has shifted. Utility Model Content

[0004] The purpose of this invention is to provide a leveling device for a cigarette rolling machine, so as to accurately measure whether the heights of the first leveling device and the second leveling device are consistent, and whether the center of the leveling device is offset relative to the center of the suction guide rail.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A positioning device for a cigarette machine leveling device, the leveling device comprising a first leveling device and a second leveling device arranged in a V-shape, wherein the positioning device includes:

[0007] A measuring block having a side extending in the width direction, wherein at least one end of the side is provided with a centering scale line;

[0008] One end of the measuring block abuts against the wire-suction guide rail, and the other end abuts against the leveling device, which can determine whether the heights of the first leveling device and the second leveling device are consistent.

[0009] As an optional solution for the positioning device of the cigarette machine leveler, the width of the measuring block is equal to the width of the suction guide rail, and one end of the measuring block is provided with the centering scale line.

[0010] As an optional solution for the positioning device of the cigarette machine leveler, the positioning device further includes a fixing block, the end of the measuring block away from the centering scale line is retractably connected to the fixing block, and the width of the fixing block is equal to the width of the suction guide rail.

[0011] As an optional solution for the positioning device of the cigarette machine leveler, a connecting block is provided at the end of the measuring block away from the centering scale line, and a connecting groove is provided at one end of the fixing block. The connecting block is retractably disposed in the connecting groove.

[0012] As an optional solution for the positioning device of the cigarette machine leveler, the connecting block is provided with an oblong hole extending along the height direction of the measuring block, and a connecting hole is provided in the connecting groove, through which the fastener passes and connects to the connecting hole.

[0013] As an optional positioning device for the cigarette machine leveler, the fastener is a fastening screw, the connecting hole is a threaded hole, and the stud of the fastening screw passes through the oblong hole and is screwed into the threaded hole.

[0019] As an optional solution for the positioning device of the cigarette machine leveler, the accuracy of the centering scale line is 0.2mm to 0.8mm.

[0020] The beneficial effects of this utility model are:

[0021] The leveling device for a cigarette machine provided by this utility model includes a measuring block. At least one end of the side of the measuring block extending along its width is provided with a centering scale line. When positioning the first and second leveling devices arranged in a V-shape, the suction guide rail moves away from the leveling devices, bringing one end of the measuring block into contact with the bottom of the suction guide rail. At this time, one end of the side of the measuring block contacts the first and / or second leveling devices, thereby enabling accurate measurement of whether the heights of the leveling devices are consistent. Furthermore, by determining that the centerline of the centering scale line is located at the center of the suction guide rail, and by observing the position of the first leveling disc of the first leveling device and the second leveling disc of the second leveling device relative to the centerline of the centering scale line near the leveling device, it is determined whether the center of the leveling device is offset from the center of the suction guide rail. This leveling device for a cigarette machine can accurately position the leveling devices, ensuring that the center of the leveling device does not shift relative to the center of the suction guide rail, and that the heights of the first and second leveling devices are consistent. At the same time, it greatly shortens the adjustment time of the leveler, improves maintenance efficiency, and reduces the rejection rate of empty cigarette ends. Attached Figure Description

[0034] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The working principle of the cigarette machine's tobacco suction forming and weight control system is as follows: Using negative pressure air, the tobacco supplied by the feeding system is drawn upwards along the vertical air duct and adsorbed onto the suction belt. With the cyclical movement of the suction belt, a continuous tobacco bundle is formed. Under the action of the weight control device, the leveling device moves up and down according to the change in tobacco density in the tobacco strip, trimming the supplied tobacco bundle to ensure a basically uniform cross-section and minimal weight deviation along the specified length. The tobacco trimmed by the leveling device is then fed to the lower part of the feeding system for reuse by the spiral tobacco return device and the return vibrating trough.

[0037] like Figure 1 As shown, the leveling device 100 includes a base 103 and a first leveling device 101 and a second leveling device 102 arranged in a V-shape. The first leveling device 101 includes a first leveling plate 1011 and a first drive shaft 1012. The second leveling device 102 includes a second leveling plate 1021 and a second drive shaft 1022. The first drive shaft 1012 and the second drive shaft 1022 are mounted on the base 103 in a V-shape. The first leveling plate 1011 is connected to the top end of the first drive shaft 1012, and the second leveling plate 1021 is connected to the top end of the second drive shaft 1022. The first drive shaft 1012 and the second drive shaft 1022 can be raised and lowered relative to the base 103 to adjust the height of the first leveling plate 1011 and the second leveling plate 1021 to adapt to the processing of cigarettes of different specifications.

[0038] After long-term use, the first leveling plate 1011 and the second leveling plate 1021 of the leveling device 100 may wear or be damaged. It is necessary to disassemble the first leveling plate 1011 and / or the second leveling plate 1021 for repair or replacement. After the repair or replacement is completed, the leveling device 100 after reinstallation must ensure that the height of the first leveling plate 1011 and the second leveling plate 1021 are consistent.

[0039] In the prior art, because the first leveling plate 1011 and the second leveling plate 1021 are tilted, it is impossible to accurately measure whether the heights of the first leveling plate 1011 and the second leveling plate 1021 are consistent, and whether the center of the leveler 100 has shifted.

[0040] like Figures 2-6 As shown, this embodiment provides a positioning device for a cigarette machine leveler. The positioning device includes a measuring block 1, which has a side extending along its width. At least one end of the side has a centering scale line 11. One end of the measuring block 1 abuts against the suction guide rail 200, and the other end abuts against the leveler 100. It can determine whether the heights of the first leveler 101 and the second leveler 102 are consistent. The centering scale line 11 can measure whether the centers of the first leveler 101 and the second leveler 102 are offset from the center of the suction guide rail 200.

[0041] The suction chamber uses a parallelogram mechanism for lifting and lowering. When the suction guide rail 200 of the suction chamber is in the working position, the gap between it and the first leveling plate 1011 and the second leveling plate 1021 is only 0.3mm to 0.5mm, which trims the initial shape of the supplied tobacco bundle. During the debugging of the cigarette machine, the axial position of the suction guide rail 200 needs to be adjusted. After the adjustment is completed, it must be ensured that the center of the leveling device 100 does not deviate relative to the center of the suction guide rail 200, so as to ensure accurate trimming of the initial shape of the tobacco bundle and reduce the rejection rate of empty tobacco paper.

[0042] Since the gap between the suction guide 200 and the first leveling plate 1011 and the second leveling plate 1021 is only 0.3mm to 0.5mm when the suction guide 200 is in the working position, it is impossible to measure the height and center position of the leveling device 100. When positioning the leveling device 100 using the positioning device of the cigarette machine leveling device provided in this embodiment, the suction chamber is driven to rise by the parallelogram mechanism. At this time, the axial position of the suction chamber will not change. The measuring block 1 is placed between the suction guide 200 and the leveling device 100, and one end of the measuring block 1 is abutted against the bottom surface of the suction guide 200, ensuring that the center line 111 of the centering scale line 11 is aligned with the center of the suction guide 200. First, observe whether both the first leveling plate 1011 and the second leveling plate 1021 are in contact with the other end of the measuring block 1. If either the first leveling plate 1011 or the second leveling plate 1021 is not in contact with the other end of the measuring block 1, it indicates that the heights of the first leveling device 101 and the second leveling device 102 are inconsistent. If the first leveling plate 1011 is not in contact with the other end of the measuring block 1, adjust the height of the first drive shaft 1012 to make the first leveling plate 1011 in contact with the other end of the measuring block 1, thus achieving the same height for the first leveling device 101 and the second leveling device 102. If the second leveling plate 1021 is not in contact with the other end of the measuring block 1, adjust the height of the second drive shaft 1022 to make the second leveling plate 1021 in contact with the other end of the measuring block 1, thus achieving the same height for the first leveling device 101 and the second leveling device 102. Then observe the distance between the center line 111 of the centering scale line 11 near the end of the leveling device 100 and the edge of the first leveling plate 1011 near the second leveling plate 1021 (hereinafter collectively referred to as the first centering edge) and the edge of the second leveling plate 1021 near the first leveling plate 1011 (hereinafter collectively referred to as the second centering edge). If the distance between the center line 111 of the centering scale line 11 and the first centering edge is equal to the distance to the second centering edge, it indicates that the center of the leveling device 100 has not shifted. If the distance between the center line 111 of the centering scale line 11 and the first centering edge is different from the distance to the second centering edge, then adjust the position and structure of the base 103 so that the distance between the center line 111 of the centering scale line 11 and the first centering edge is equal to the distance to the second centering edge.

[0043] The positioning device for the cigarette machine leveler provided in this embodiment can quickly solve the problem of the center of the suction guide rail 200 deviating from the center of the leveler 100 during the installation and debugging of the cigarette machine; it can also be used to adjust and measure the height of the first leveler 101 and the second leveler 102 after routine maintenance of the leveler 100, ensuring the adjustment accuracy of the leveler 100, while greatly shortening the adjustment time, improving maintenance efficiency, and reducing the rate of discarding empty cigarette ends.

[0044] In one embodiment, the accuracy of the centering scale line 11 is 0.2 mm to 0.8 mm. The higher the accuracy of the centering scale line 11, the higher the alignment accuracy between the leveler 100 and the wire-feeding guide rail 200. In this embodiment, the accuracy of the centering scale line 11 is 0.5 mm.

[0045] In one embodiment, the width of the measuring block 1 is equal to the width of the suction guide rail 200, and a centering scale line 11 is provided at one end of the measuring block 1. By setting the width of the measuring block 1 to be equal to the width of the suction guide rail 200, during measurement, the two edges along the width direction of the end of the measuring block 1 that abuts against the suction guide rail 200 are aligned with the two edges along the width direction of the suction guide rail 200, respectively. The centering scale line 11 is located at the end of the measuring block 1 that abuts against the leveling device 100. Since the centerline 111 of the centering scale line 11 is located at the center position of the measuring block 1 along the width direction, the center of the suction guide rail 200 is located on the centerline 111 of the centering scale line 11. It is only necessary to confirm whether the distance between the centerline 111 of the centering scale line 11 and the first centering edge is equal to the distance between the centerline and the second centering edge. This arrangement saves centering measurement time and improves the efficiency of centering measurement.

[0046] In this embodiment, centering scale lines 11 are provided on both opposite sides of one end of the measuring block 1 along the width direction. With this arrangement, the measuring personnel can observe whether the center of the level 100 is offset from the center of the wire suction guide 200 from both the left and right sides.

[0047] Of course, in other embodiments, both ends of the measuring block 1 are provided with centering scale lines 11, and the width of the measuring block 1 is not limited. During measurement, first ensure that the center line 111 of the centering scale line 11 at the end of the measuring block 1 that abuts against the wire suction guide 200 is located at the center position of the wire suction guide 200, and then observe whether the distance between the center line 111 of the centering scale line 11 at the end of the measuring block 1 that abuts against the level 100 and the first centering edge is equal to the distance between the center line 111 and the second centering edge.

[0048] To ensure that the positioning device can be used with levelers 100 at different heights, that is, to ensure that the positioning device can be placed between wire-suction guide rails 200 and levelers 100 at different intervals, measurement time can be further saved and measurement efficiency improved.

[0049] In one embodiment, the positioning device further includes a fixing block 2. The end of the measuring block 1 furthest from the centering scale line 11 is retractably connected to the fixing block 2. The width of the fixing block 2 is equal to the width of the wire-suction guide rail 200. By adding a fixing block 2 at the end of the measuring block 1 furthest from the centering scale line 11, and using the fixing block 2 as the other end of the measuring block 1, the measuring block 1 is retractably set relative to the fixing block 2, making the height of the positioning device adjustable to accommodate wire-suction guide rails 200 and levelers 100 with different spacing, thus improving the versatility of the positioning device.

[0050] In one embodiment, a connecting block 3 is provided at the end of the measuring block 1 away from the centering scale line 11, and a connecting groove 21 is provided at one end of the fixing block 2. The connecting block 3 is telescopically disposed within the connecting groove 21. By cooperating with the connecting groove 21, the cooperation length between the connecting block 3 and the connecting groove 21 can be adjusted, thereby achieving height adjustment of the positioning device.

[0051] Specifically, the connecting block 3 is configured as a flat block, and the end of the connecting block 3 away from the measuring block 1 is configured as an arc-shaped end face; correspondingly, one end of the connecting groove 21 is connected to one end face of the fixing block 2, and the other end is configured as an arc-shaped inner wall that matches the arc-shaped end face. When the height of the positioning device is at its minimum, the arc-shaped end face of the connecting block 3 abuts against the arc-shaped inner wall of the connecting groove 21.

[0052] In one embodiment, the connecting block 3 and the measuring block 1 are integrally formed. By making the connecting block 3 and the measuring block 1 an integral structure, there is no need to set up a connection structure between the connecting block 3 and the measuring block 1, which makes the structure simpler, easier to manufacture, and saves costs.

[0053] In one embodiment, the width of the connecting block 3 is smaller than the width of the measuring block 1. With this arrangement, when the connecting block 3 is connected to the fixing block 2, the opposite side walls of the connecting groove 21 restrict the opposite side walls of the connecting block 3, thereby ensuring that the center line of the fixing block 2 and the center line of the measuring block 1 are on the same straight line, further improving the alignment accuracy of the leveling device 100 and the wire suction guide 200.

[0054] In one embodiment, such as Figures 3-5 As shown, the connecting block 3 has an oblong hole 31 extending along the height direction of the measuring block 1, and a connecting hole 211 is provided in the connecting groove 21. The fastener passes through the oblong hole 31 and connects with the connecting hole 211. The length of the oblong hole 31 and the position of the connecting hole 211 in the connecting groove 21 determine the height adjustment of the positioning device. This connection method has a simple structure, is easy to process and manufacture, and has higher connection stability between the connecting block 3 and the fixing block 2.

[0055] Of course, in other embodiments, a spring can also be provided at the end of the connecting groove 21 away from the connecting block 3. When the positioning device is placed between the wire suction guide 200 and the level 100, the spring can be compressed according to the distance between the wire suction guide 200 and the level 100 to automatically adjust the height of the positioning device so that the positioning device adapts to the distance between the wire suction guide 200 and the level 100.

[0056] Specifically, the fastener is a fastening screw (not shown in the figure), the connecting hole 211 is a threaded hole, and the stud of the fastening screw passes through the oblong hole 31 and is screwed into the threaded hole. When the fastening screw fixes the connecting block 3, the stud of the fastening screw is screwed into the threaded hole, and the fastening head of the fastening screw abuts against the side of the connecting block 3 away from the threaded hole, so as to ensure the stability of the connection between the connecting block 3 and the fixing block 2.

[0057] Of course, in other embodiments, the fasteners can also be set as fastening bolts and nuts to fix the connecting block 3 and the fixing block 2.

[0058] Furthermore, the outer periphery of the fastening head of the fastening screw is knurled to increase the friction between the hand and the fastening screw when manually tightening and loosening the fastening screw, making it easier to adjust the extension and retraction of the connecting block 3 and improving the adjustment efficiency.

[0059] In one embodiment, the connecting hole 211 is located at the center of the connecting groove 21. This arrangement shortens the adjustment height of the positioning device, but ensures the stability of the positioning device height. It also prevents the connecting block 3 from being too close to the through end of the connecting groove 21, which would result in an unstable fit between the connecting block 3 and the fixed block 2 after they are connected due to the small contact area between the connecting block 3 and the connecting groove 21. This would cause the measuring block 1 to become skewed, resulting in a change in the position of the centering scale line 11 of the measuring block 1, and thus affecting the centering accuracy of the leveler 100 and the wire suction guide rail 200.

[0060] In one embodiment, the connecting groove 21 is provided through one side of the fixing block 2. On the one hand, this facilitates the processing of the connecting groove 21; on the other hand, when the fastening screw fixes the connecting block 3 and the fixing block 2, it is convenient for the fastening screw to pass through the waist-shaped hole 31 and be screwed into the threaded hole, which further improves the adjustment efficiency.

[0061] In one embodiment, the height of the connecting block 3 is the same as the height of the measuring block 1, and the height of the fixing block 2 is greater than the height of the connecting block 3. Setting the height of the connecting block 3 and the measuring block 1 to be the same maximizes the height adjustment range of the positioning device while ensuring the stability of the connection between the measuring block 1 and the fixing block 2. The height of the fixing block 2 is greater than the height of the connecting block 3, so that the fixing block 2 has sufficient height to accommodate the connecting groove 21 that mates with the connecting block 3.

[0062] In this embodiment, the measuring block 1 has a length of 16mm, a width of 9.2mm, and a height of 40mm, and the connecting block 3 has a height of 40mm. The fixing block 2 has a length of 16mm, a width of 9.2mm, and a height of 60mm.

[0063] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
