Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tools for cigarette machine calibration, specifically to an auxiliary adjustment fixture for a cigarette machine tobacco strip delivery system. Background Technology
[0002] The cigarette rolling machine mainly consists of three parts: the feeding and forming unit (VE), the rolling and forming unit (SE), and the filter tip assembly unit (MAX), which are responsible for feeding and forming the cigarettes, rolling and forming the cigarettes, and assembling the filter tips, respectively. During the double-length cigarette transfer process between SE and MAX, the "spider-hand" in the cigarette transfer system plays a crucial role. The spider-hand uses its suction groove to pick up the cigarettes from the guide rail and precisely deliver them to the receiving groove of the first receiving drum of the MAX filter tip assembly machine, thus ensuring a stable transfer of the cigarettes.
[0003] When adjusting the cigarette bar delivery system, the clearance between the gear and the drive gear, as well as the clearance between the gear and the pinion shaft, must be consistent. However, the method used in current maintenance manuals to align the spider arm position by aligning the gauge holes is difficult to achieve uniform clearance. Therefore, in actual adjustment, it is often necessary to manually calibrate the position of each spider arm one by one. In addition, there are various methods for adjusting the positioning of the spider arm in cigarette rolling machines, and different models require different adjustment tools and methods, with a lack of unified standards for the number and specifications of tools.
[0004] When using 90° right-angle fittings for calibration, the fitting base is typically placed on a V-shaped guide rail to maintain horizontality. However, if the guide rail itself is not perfectly level, it can easily lead to errors in adjustment accuracy, resulting in the spider arm not being in the correct position, thus affecting the stability of cigarette stick connection. This can cause cigarette stick breakage, smoke splattering, and in severe cases, even blockage of the MAX splicing block, causing equipment downtime. This not only affects production efficiency and increases auxiliary material consumption but may also lead to market complaints.
[0005] The inconsistent dimensions and lack of standardized design of existing right-angle components exacerbate debugging errors and affect the stability and consistency of equipment operation. This problem is particularly prominent in actual production and urgently needs to be addressed by improving adjustment methods and tools. Utility Model Content

[0032] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0033] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.
[0034] This utility model provides an auxiliary adjustment fixture for a cigarette machine tobacco strip delivery system, comprising:
[0035] The fixture body 3 includes a horizontally placed base 3a and a vertically placed measuring arm 3b. The bottom of the measuring arm 3b is fixedly connected to the edge of the base 3a. The measuring arm 3b has a measuring surface on one side near the left or right edge of the base 3a. The measuring surface is a planar structure.
[0036] Scale 1 is set on measuring arm 3b.
[0037] Level 2 is fixed on the upper surface of base 3a.
[0038] The leveling mechanism includes two parts, left and right, respectively located on the left and right sides of the lower surface of the base 3a. The leveling mechanism includes a stud 4 and a support leg 5. The upper end of the stud 4 is fixed to the lower surface of the base 3a, and the support leg 5 has a threaded hole. The support leg 5 is threaded with the bottom of the stud 4 through the threaded hole.
[0039] The fixture body 3 is L-shaped and includes a base 3a and a measuring arm 3b. The base 3a is the shorter side, and the measuring arm 3b is the longer side. The measuring arm 3b is vertically mounted on the base 3a. When the base 3a is placed horizontally, the measuring arm 3b remains vertical. The base 3a and the measuring arm 3b of the fixture body 3 are integrated to prevent tilting or movement during measurement. The width of the base 3a in the front-to-back direction is greater than the width of the measuring arm 3b in the front-to-back direction.
[0040] The measuring arm 3b has a measuring surface on one side near the end of the base 3a. When in use, the measuring surface is placed against the object being measured.
[0041] The scale 1 includes multiple spaced graduation lines and numbers indicating the graduation lines. One end of each graduation line points towards the measuring surface for easy reading of the height of the scale 1.
[0042] like Figure 3 As shown, the level 2 is a bubble level. The bubble level includes a sealed outer shell containing liquid, and the liquid contains bubbles 2b. A positioning line 2a is provided on the sealed outer shell; when the bubble 2b is positioned in the middle of the positioning line 2a, the bubble level is in a horizontal state. One bubble level can be used, or two mutually perpendicular bubble levels can be used.
[0043] Appendix Figure 1-3 In the specific implementation, only one bubble level is provided. With only one bubble level, the measuring direction of the bubble level is perpendicular to the measuring surface.
[0044] With two bubble levels set up, the two bubble levels are perpendicular to each other, both are perpendicular to the extension direction of the measuring arm 3b, and one of the levels 2 is perpendicular to the measuring surface. That is, the measuring arm 3b and the two mutually perpendicular bubble levels are parallel to the three axes of the orthogonal coordinate system.
[0045] A U-shaped groove is formed on the upper surface of the base 3a. The level 2 is embedded in the U-shaped groove and is set parallel to the base 3a. When the level 2 is level, the base 3a is in a level state.
[0046] The lower surface of the base 3a is provided with a threaded hole, and the top of the stud 4 is screwed into the threaded hole. The top of the stud 4 is screwed onto the base 3a, and the height of the stud 4 can be adjusted when the stud 4 rotates. At the same time, the support leg 5 is screwed onto the bottom of the stud 4, and the height of the support leg 5 can also be adjusted independently when the support leg 5 rotates while the stud 4 remains stationary.
[0047] The fixture body 3 is made of metal. The fixture body 3 is cast, with the measuring surface machined to ensure its flatness. The U-shaped groove for mounting the level 2 is machined and perpendicular to the measuring surface.
[0048] like Figure 4 and Figure 5 As shown. In use, the support leg 5 is mounted on the cigarette bar guide rail. The tilt angle of the base 3a can be adjusted by adjusting the two leveling mechanisms on the left and right sides respectively. The leveling mechanism, together with the level 2, adjusts the base 3a to a horizontal state. Then, rotate the trolley so that the air intake groove 7 of the leftmost spider hand transfer arm 6 is exactly at the intersection position with the drum groove of the receiving drum. The measuring surface of the measuring arm 3b is in contact with the spider hand, and the scale value 'a' corresponding to the rightmost spider hand is read. When each trolley rotates to the rightmost spider hand at this scale value 'a', it can be ensured that the equipment is in the intersection position of the cigarette bar transfer system.
[0049] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0050] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0051] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
