Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machine maintenance, and more specifically to a tool for removing a linear bearing in a separating block of a separating wheel of a cigarette making machine. Background Art

[0002] The separation wheel of a cigarette making machine is an extremely important component of the machine. Its main function is to absorb and transfer the single-length filter-free cigarettes cut in the previous process to the inner and outer separation blocks of the separation wheel assembly. When the separation wheel rotates counterclockwise, the separation blocks move away from each other, completely separating the single-length cigarettes.

[0003] During this process, the separation wheel relies on linear bearing movement.

[0004] Since the separation wheel is a high-frequency moving component, it requires regular maintenance and upkeep. The linear bearing, which serves as the main guide mechanism, needs to be disassembled, replaced or maintained.

[0005] The separation block is a relatively special structure with a flat surface at one end and an inclined surface at the other end. The hole for installing the linear bearing is located in the outer area of the separation block, and due to the performance requirements of the separation block, the end of the linear bearing cannot exceed the surface of the separation block.

[0006] This brings several problems: when using the pulling method to remove the linear bearing, a load-bearing platform needs to be applied on the flat side of the separation block, but there are steps on the flat side of the separation block, which is not easy to use as a load-bearing platform. Therefore, more solutions will use the method of knocking from the other side to remove the linear bearing.

[0007] A groove structure for removal is provided inside the linear bearing. A tooling is designed to remove the linear bearing by knocking, and can provide sufficient pre-tightening force to prevent it from loosening during the knocking process. Utility Model Content

[0008] One purpose of the present utility model is to provide a new technical solution for removing the linear bearing in the separating block of the separating wheel of a cigarette making machine, so as to effectively solve the problems raised in the above-mentioned background technology.

[0034] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] like Figure 1-Figure 3 As shown, a tool for removing the linear bearing in the separation block of the separation wheel of a cigarette making machine includes a long guide rod 1, a first limit plate 2, a second limit plate 3, a hook assembly 4, a pre-tightening bolt 5 and a tightening sleeve 6.

[0036] The long guide rod 1 includes a first section 11 and a second section 12 that are continuously arranged. The first limiting plate 2 and the second limiting plate 3 are arranged in the transition area between the first section 11 and the second section 12. The installation area of the hook assembly 4 is between the first limiting plate 2 and the second limiting plate 3.

[0037] In this solution, the end of the second section 12 is a striking end, the first section 11 and the second section 12 are an integrated structure, the diameter of the first section 11 is larger than the diameter of the second section 12, and the first limiting plate 2 and the second limiting plate 3 are connected to the long guide rod 1 by welding.

[0038] The hook assembly 4 includes a base 41, two bent arms 42 and two hooks 43. A through hole is set at the center of the base 41, and the through hole is set in the installation interval. The base 41 is constrained in the installation interval by the first limit plate 2 and the second limit plate 3. The bent arm 42 extends outward from the center of the base 41, and the hook 43 is set at the terminal end of the bent arm 42. The hook 43 is set outward to clamp the groove 8 on the inner wall of the linear bearing 7.

[0039] In this solution, the hook assembly 4 is an integrally formed structure. The material of the hook assembly 4 is spring steel. The base 41 and the bent arm 42 of the hook assembly 4 are both made of spring steel with a thickness of more than 1 cm. On the one hand, it provides good elastic deformation ability, and on the other hand, it can prevent cracking during knocking.

[0040] The tightening sleeve 6 includes a force transmission sleeve 61 and a support sleeve 62. The force transmission sleeve 61 is slender, and the support sleeve 62 is an arc surface with an arc transition on the outer circumference. The support sleeve 62 and the force transmission sleeve 61 are connected together, and the support sleeve 62 is arranged between the two bent arms 42 of the hook assembly 4; the force transmission sleeve 61 and the support sleeve 62 are an integrally formed structure, and the length ratio of the force transmission sleeve 61 to the support sleeve 62 exceeds 4:1.

[0041] The pre-tightening bolt 5 is installed at the end of the second section 12. The end of the second section 12 is provided with an external thread. The pre-tightening bolt 5 is screwed on the external thread. The pre-tightening bolt 5 is used to drive the tightening sleeve 6 to move toward the hook assembly 4. The support sleeve 62 is used to drive the two bent arms 42 of the hook assembly 4 to deform outward.

[0042] The tightening sliding sleeve 6 and the long guide rod 1 are both made of steel, which provides sufficient rigidity, is not easy to deform, and is resistant to knocking.

[0043] Working principle description:

[0044] When the linear bearing 7 needs to be taken out, the linear bearing 7 is placed in a suitable position so that it is flat, with the installation port side of the linear bearing 7 facing downward and the inclined side of the separation block 9 facing upward.

[0045] First, loosen the pre-tightening bolt 5, push the sliding sleeve 6 away from the hook assembly 4, and insert the tooling from bottom to top. The bent arm 42 of the hook assembly 4 is slightly deformed by the inner wall of the linear bearing 7 and smoothly enters the interior of the linear bearing. When passing through the groove 8, the hook assembly 4 recovers its deformation and enters the groove 8. The operator can hear a click and then stop.

[0046] Then screw in the pre-tightening bolt 5 to move the tightening sleeve 6 forward. The outer wall of the supporting sleeve 62 at the front end of the tightening sleeve 6 contacts and squeezes the bent arm 42 , so that the hook 43 is tightly pressed into the groove 8 .

[0047] Then tap the end of the second section 12 of the long guide rod 1 to remove the linear bearing 7.

[0048] After taking it out, loosen the pre-tightening bolt 5 to reset it and fully remove the linear bearing 7.

[0049] The advantage of using a hook structure is that linear bearings are different from other bearings. They have several rows of balls inside. Compared with some annular structures, the hook structure can avoid the balls, prevent damage to the balls, and reduce bearing damage.

[0050] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
