[0029] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] In order to solve the technical problems in the prior art, the utility model proposes a universal removal tool for the driving wheel 4 of a cigarette making machine, such as Figure 1 As shown, it includes: a bracket 1, a pulling assembly 2, and a supporting assembly 3; the pulling assembly 2 includes a pulling rod 22 and a pulling claw 21, as shown in FIG. Figure 4 As shown, the first end of the pull rod 22 (i.e. Figure 4 The lower end of the middle end of the pull rod 22 is installed on the bracket 1 and can move along the radial direction of the transmission wheel 4 on the bracket 1. The pull claw 21 is arranged at the second end of the pull rod 22 (i.e. Figure 4 The pull claw 21 is used to abut against the inner side of the transmission wheel 4 (such as Figure 7 The support assembly 3 includes a support rod 31, as shown Figure 5 As shown, the support rod 31 is threadedly mounted on the bracket 1 and can move radially along the transmission wheel 4 on the bracket 1, and the support rod 31 is located on the radial outside of the pull rod 22 along the transmission wheel 4, and the inner end of the support rod 31 is against the equipment wall panel 6 in the cigarette making machine.

[0031] The tooling can slide along the radial direction of the transmission wheel 4, so it can realize the removal of transmission wheels 4 of different sizes and structures, thereby improving the maintenance efficiency of the transmission wheel 4, while avoiding rough operations such as knocking, punching and prying, and improving the safety of the maintenance process. In addition, the support rod 31 is located on the radial outside of the pull rod 22. During disassembly, the support rod 31 is pressed against the equipment wall panel 6 to prevent damage to the electronic components in the core of the transmission wheel 4. In addition, since a large number of transmission wheels 4 and other components are arranged on the equipment wall panel 6, the support rod 31 in the tooling can also slide along the radial direction on the bracket 1 to avoid other transmission wheels 4 or other components on the wall panel, prevent other transmission wheels 4 or other components from being damaged, improve the adaptability of the tooling, and ensure that transmission wheels 4 of different diameters and different positions can be smoothly removed.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the bracket 1 includes a first support plate 11 and a second support plate 12, the first support plate 11 is a straight plate, the second support plate 12 includes a transverse plate 121 and a connecting plate 122, the transverse plate 121 and the connecting plate 122 form an L shape, one end of the connecting plate 122 is connected to the transverse plate 121, and the other end is connected to the first support plate 11, and two second support plates 12 are installed on the first support plate 11, and the length of the two second support plates 12 is greater than the length of the first support plate 11, as shown in FIG. Figure 1 As shown, the pull rod 22 of the pulling assembly 2 is installed on the first support plate 11 , and the support rod 31 of the support assembly 3 is installed on the second support plate 12 .

[0033] Since the transmission wheel 4 is located inside the device housing, when disassembling, the inspection door of the device is opened and the tooling is pushed into the device, and the internal space of the device is limited, therefore, the present application designs the bracket 1 as a layered structure of a first support plate 11 and a second support plate 12, on the one hand, to avoid interference between the ball sleeve 32 and the pull rod 22; on the other hand, when in use, the first support plate 11 enters the interior of the device, which is convenient for use in the narrow space inside the device, and provides solid support for the claw 21 and the pull rod 22. The second support plate 12 is located outside the device, providing solid support for the support rod 31.

[0034] The first support plate 11 is provided with a first slide groove 111, and there are two first slide grooves 111, which are symmetrically arranged on the first support plate 11 and arranged along the radial direction of the transmission wheel 4, and the pull rod 22 is installed on the first slide groove 111. The first support plate 11 is 320 mm long, and the length of the first slide groove 111 is greater than the maximum diameter of the transmission wheel 4, so as to adapt to transmission wheels 4 of various sizes.

[0035] like Figure 1 , Figure 4 As shown, the pull rod 22 is a threaded rod, and the threaded rod passes through the first slide groove 111. A pair of first locking nuts 23 are installed on the threaded rod, and the pair of first locking nuts 23 are respectively located on both sides of the first support plate 11. The cross section of the pull claw 21 is an L-shaped grab hook, and the pull claw 21 is rotatably installed on the pull rod 22. Specifically, it can be connected by threads. Through the rotational connection between the pull claw 21 and the pull rod 22, when installing the pull claw 21, the pull claw 21 can be rotated 90 degrees first, so that it can pass through the gap between the transmission wheel 4 and other components. After the pull claw 21 passes through the gap, it is rotated back 90 degrees to form a shape as shown in the figure. Figure 7 The device shown in the figure can thus remove the transmission wheel 4 which is surrounded by obstructions and in a narrow space.

[0036] like Figure 1 , Figure 5 As shown, the support assembly 3 also includes a ball sleeve 32, the support rod 31 is threadedly connected to the ball sleeve 32, and the ball sleeve 32 is installed on the second slide groove 123 of the second support plate 12. The ball screw principle is adopted. When the support rod 31 is rotated, the ball sleeve 32 drives the bracket 1 to move axially. The support assembly 3 also includes a second locking nut 33, and the second locking nut 33 is installed on the support rod 31. The ball sleeve 32 and the second locking nut 33 are respectively located on both sides of the second support plate 12. After adjusting the position of the support rod 31, the second locking nut 33 is used to fix the support rod 31 to the second support plate 12. A handle 34 is provided at the outer end of the support rod 31, and the handle 34 is arranged perpendicular to the support rod 31. The handle 34 can be as follows Figure 5The rod shown may also be other structures such as a hand wheel.

[0037] The support rod 31 adopts a ball screw, with a handle 34 installed at one end and the other end against the equipment wall panel 6. The ball sleeve 32 is installed on the bracket 1 and the position is adjustable. By rotating the pull rod 22, the bracket 1 can be driven to drive the pull claw 21 to take out the transmission wheel 4. The ball sleeve 32 is installed on the second slide groove 123 of the second support plate 12, and the ball sleeve 32 can move along the second slide groove 123 to adapt to different internal spaces of the equipment.

[0038] Further, such as Figure 5 , Figure 6 As shown, the support assembly 3 further includes a rotating seat 35, the rotating seat 35 includes a base 351, a pressure bearing 352 and a connecting seat 353, and the connecting seat 353 is installed at the inner end of the support rod 31, for example, by threaded connection. The pressure bearing 352 is located between the connecting seat 353 and the base 351, and the connecting seat 353 and the base 351 are rotatably connected through the pressure bearing 352, and the base 351 abuts against the equipment wallboard 6. By arranging the rotating seat 35 at the inner end of the support rod 31, the friction between the support rod 31 and the equipment wallboard 6 can be reduced when rotating, and it is more labor-saving to use.

[0039] When in use, clamp the pulling claw 21 of the tool on the transmission wheel 4, move the pulling claw 21 to make it close to the transmission wheel 4, adjust the position of the support rod 31, rotate the support rod 31 to make it rest against the equipment wall panel 6, continue to rotate the handle 34 of the support rod 31, drive the bracket 1 to drive the pulling claw 21 to pull the transmission wheel 4 out of the transmission shaft 5.

[0040] Of course, it is understandable that a top column can also be installed on the middle thread of the first support plate 11. When there is no electronic device in the middle of the transmission wheel 4, the middle top column can be used to press against the transmission shaft 5 for disassembly.

[0041] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
