Description

Technical Field

[0001] This utility model relates to the field of suction ribbon installation technology, and in particular to a suction ribbon replacement tool and a cigarette rolling machine. Background Technology

[0002] The tobacco suction cable is a crucial component in the tobacco manufacturing industry. It drives the movement of the tobacco bundle adhered to it, forcibly delivering the evenly distributed tobacco bundle to the cigarette holder, where it merges with the cigarette paper and is then rolled into shape, thus achieving stable tobacco delivery. Therefore, the suction cable needs frequent replacement to ensure effective suction and delivery. Traditionally, operators manually pull the suction cable to engage it in the groove of the suction guide. Because the suction cable is already tensioned and fixed, pulling it causes greater deformation at the tensioned point compared to other areas, reducing its lifespan. Furthermore, manually pulling the tensioned cable is labor-intensive and inefficient.

[0003] In existing technologies, a mounting fixture is typically used to replace the suction cable. This fixture includes an arc-shaped plate and a push-in boss. The central angle of the arc-shaped plate is less than 180°. The push-in boss is located on the circumferential outer surface of the arc-shaped plate, gradually widening along its circumferential direction. When installing the suction cable, the suction cables from both the front and rear tracks are first placed over the fixture and secured to the drive wheel. Then, the suction cable is placed on the arc-shaped plate. The fixture is rotated using a wrench, and the push-in boss aligns the suction cable with the groove. A 180° rotation of the fixture completely guides the suction cable into the groove. The fixture is then rotated again to remove the suction cable from the fixture, and the fixture is then removed. However, the wrench is difficult to operate during rotation, and repeated rotation with the wrench causes wear on both the fixture and the wrench, leading to decreased sensitivity during subsequent rotations.

[0034] This embodiment provides a tooling for changing suction ribbons, such as... Figures 1-3 As shown, a tooling body 1 and a drive assembly 2 are used to drive the suction ribbon drive wheel (not shown) to rotate. The tooling body 1 is connected to the suction ribbon drive wheel and has at least two connecting holes 11. The at least two connecting holes 11 are evenly distributed around the circumference of the tooling body 1. The drive assembly 2 includes a drive member 21. One end of the drive member 21 can be inserted into at least two connecting holes 11, and the outer wall of the drive member 21 can fit against the inner wall of the connecting hole 11. The drive member 21 can drive the tooling body 1 to rotate.

[0035] When replacing the suction ribbon, the suction ribbon is first placed on the suction ribbon drive wheel. The fixture body 1, as the basic support structure of the suction ribbon replacement fixture, is precisely connected to the suction ribbon drive wheel. One end of the drive component 21 is inserted into at least two connecting holes 11 on the fixture body 1, thereby driving the fixture body 1 to rotate. The above arrangement avoids excessive torque on the part of the drive component 21 that contacts the connecting holes 11 when driving the fixture body 1 to rotate, which would cause wear on the drive component 21 or the connecting holes 11. This improves the reliability of the suction ribbon replacement fixture and increases the suction ribbon replacement efficiency.

[0036] Optionally, in this embodiment, the tooling body 1 is detachably connected to the suction ribbon drive wheel. Specifically, it is a threaded connection. In other embodiments, the tooling body 1 can also be snapped onto or glued to the suction ribbon drive wheel. No limitations are imposed here.

[0037] Furthermore, such as Figure 3 As shown, the driving component 21 includes a connecting portion 212 and at least two driving portions 211. The driving portions 211 are inserted into the connecting hole 11, and their outer walls can fit against the inner wall of the connecting hole 11. The connecting portion 212 is fixedly connected to the at least two driving portions 211, and the connecting portion 212 drives the driving portions 211 to move. When an external power source transmits power to the connecting portion 212, the connecting portion 212 can convert the power into a rotational driving force and transmit it to the connected driving portion 211, thereby driving the driving portion 211 to move within the connecting hole 11, thus realizing the rotation of the tooling body 1. It should be noted that in this embodiment, the connecting portion 212 is an L-shaped connecting rod, and the driving portion 211 is a cylindrical structure. In other embodiments, the shape of the connecting portion 212 is not limited, as long as it can be fixedly connected to the driving portion 211 and can drive the driving portion 211 to move.

[0038] Optionally, in this embodiment, the connecting portion 212 drives the driving portion 211 to rotate about the axial direction of the tooling body 1. In other embodiments, the connecting portion 212 may also drive the driving portion 211 to slide about the axial direction of the tooling body 1, as long as it can drive the tooling body 1 to rotate. No limitation is made here.

[0039] Optionally, such as Figures 1-3As shown, in this embodiment, the tooling body 1 has two connecting holes 11. The driving component 21 includes two driving parts 211, which are arranged at intervals along the extension direction of the connecting part 212. The connecting hole 11 is an arc-shaped waist hole. The center line of the arc-shaped waist hole, the center line of the line connecting the center lines of the two driving parts 211, and the axis of the tooling body 1 are coaxial. The distance between the center lines of the two driving parts 211 is the same as the diameter of the connecting hole 11. This coaxial arrangement enables the driving component 21 to achieve precise force transmission and motion control when driving the tooling body 1, avoiding problems such as torque, wear, and reduced efficiency caused by misalignment. At the same time, the distance between the center lines of the two driving parts 211 is the same as the diameter of the connecting hole 11, allowing the driving parts 211 to be precisely embedded in the connecting hole 11, achieving a tight and stable connection between the tooling body 1 and the driving component 21. In actual operation, when the drive component 21 operates, the drive part 211 can efficiently and smoothly transmit power to the tooling body 1 through cooperation with the connecting hole 11, thereby driving the tooling body 1 to rotate and drive the drive wheel of the suction ribbon to rotate. In other embodiments, the tooling body 1 may also have three connecting holes 11, the drive component 21 includes three drive parts 211, the three drive parts 211 are arranged at intervals along the circumferential direction of the connecting part 212, and the connecting hole 11 is an arc-shaped waist hole, the center line of the arc-shaped waist hole, the center point of the line connecting the center lines of the three drive parts 211, and the axis of the tooling body 1 are coaxial. Alternatively, the tooling body 1 may also have four connecting holes 11, the drive component 21 includes four drive parts 211, the four drive parts 211 are arranged at intervals along the circumferential direction of the connecting part 212, and the connecting hole 11 is an arc-shaped waist hole, the center line of the arc-shaped waist hole, the center line of the line connecting the center lines of the four drive parts 211, and the axis of the tooling body 1 are coaxial, etc. No restrictions are imposed here.

[0040] Furthermore, such as Figures 1-3As shown, the connecting hole 11 includes a first hole 111 and a second hole 112 that are interconnected. The driving member 21 also includes a limiting part 213, which is fixedly connected to the second end of the driving part 211. The size of the limiting part 213 is larger than that of the driving part 211. The limiting part 213 can be limited to pass through the first hole 111 and can abut against the side of the tooling body 1 facing the suction belt drive wheel. The outer wall of the driving part 211 can fit against the inner wall of the second hole 112. When the driving member 21 is inserted into the tooling body 1, the limiting part 213 is limited to pass through the first hole 111. The connecting part 212 is rotated so that the limiting part 213 rotates in the circumferential direction of the tooling body 1. At the same time, the limiting part 213 abuts against the side of the tooling body 1 facing the suction belt drive wheel, and the outer wall of the driving part 211 fits against the inner wall of the second hole 112. The above settings effectively limit the excessive movement of the drive component 21 in the axial direction of the suction ribbon drive wheel, ensuring that the drive component 21 always remains in the accurate position during operation. This, in turn, ensures the stability and accuracy of the suction ribbon changing fixture in the drive suction ribbon drive wheel, avoids system failures or work deviations caused by improper displacement of the drive component 21, and greatly improves the working performance and reliability of the suction ribbon changing fixture.

[0041] Furthermore, such as Figure 2 As shown, a groove 13 is formed on the side of the tooling body 1 facing the suction belt drive wheel, and the inner diameter of the groove 13 is the same as the outer diameter of the suction belt drive wheel. The groove 13 allows the tooling body 1 and the suction belt drive wheel to fit tightly together, thereby achieving more efficient operation, and also facilitates the insertion of the drive part 211 and the limiting part 213 into the tooling body. It should be noted that the depth of the groove 13 is not limited.

[0042] Furthermore, such as Figure 3 As shown, the drive assembly 2 also includes a rotating member 22, which is rotatably connected to the other end of the drive member 21. This arrangement makes it more convenient for the drive member 21 to drive the tooling body 1 to rotate. It should be noted that in this embodiment, the rotating member 22 is a rotating handle. In other embodiments, the rotating member 22 can also be a handwheel or a rotatable handle, etc. No limitation is made here.

[0043] Furthermore, such as Figure 1As shown, the fixture body 1 has a mounting hole 12. The suction ribbon replacement fixture also includes a fixing member (not shown in the figure). One end of the fixing member passes through the mounting hole 12 and is connected to the suction ribbon drive wheel. The other end of the fixing member can abut against the outer surface of the fixture body 1. After the fixing member passes through the mounting hole 12, one end of the fixing member is connected to the suction ribbon drive wheel, and the other end of the fixing member can abut against the outer surface of the fixture body 1. When the other end of the fixing member abuts against the outer surface of the fixture body 1, the fixing member generates a reverse supporting force, forming a balanced force state with the end of the fixing member connected to the suction ribbon drive wheel. This not only helps to stabilize the operation of the suction ribbon drive wheel and prevent it from shaking or shifting during operation, but also further enhances the structural stability of the suction ribbon replacement fixture, providing a solid guarantee for the replacement of the suction ribbon.

[0044] Optionally, in this embodiment, the fastener is a bolt, including a bolt shank and a bolt head for fixed connection. The bolt shank passes through the mounting hole 12 and is threaded onto the suction belt drive pulley, while the bolt head abuts against the outer surface of the tooling body 1. In other embodiments, the fastener may also be a snap-fit ​​or a pin, etc. No limitation is imposed here.

[0045] Optionally, such as Figure 1 As shown, in this embodiment, the mounting hole 12 is a countersunk hole. The countersunk hole makes the structure after the fastener is fixed in place more flat and aesthetically pleasing, and also avoids scratches or obstructions that might be caused by protruding fasteners. In other embodiments, the mounting hole 12 can also be a through hole, etc. No limitation is made here.

[0046] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, the edges of the fixture body 1 are all rounded. The rounded edges reduce the potential injury to operators during the use of the suction ribbon changing fixture. Compared to sharp edges, rounded edges are safer, reducing the risk of accidental scratches; secondly, rounded edges are more aesthetically pleasing and streamlined, improving the overall visual effect. In other embodiments, the edges of the fixture body 1 may also be chamfered, etc. No limitations are imposed here.

[0047] A cigarette rolling machine includes a machine body and a suction ribbon replacement fixture. The suction ribbon replacement fixture is fixedly mounted on the machine body. By incorporating the suction ribbon replacement fixture, the cigarette rolling machine avoids excessive torque on the part of the drive component 21 that contacts the connecting hole 11 when the fixture body 1 rotates, thus preventing wear of the drive component 21 or the connecting hole 11. This improves the reliability of the suction ribbon replacement fixture and increases the efficiency of suction ribbon replacement.

[0048] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
