Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, and more specifically to a filter rubbing plate positioning tool for a cigarette assembling machine. Background Art

[0002] The filter supply system of the YJ29 assembler adopts the principle of rolling and rubbing dislocation. The filter rubbing plate mechanism, as an important functional component, needs to switch positions when the assembler is started and stopped.

[0003] Specifically, the entire filter supply system includes a staggered drum wheel, the surface of which is provided with a plurality of staggered arc grooves, and negative pressure is passed through the arc grooves for adsorbing the filter;

[0004] The filter rubbing plate mechanism includes a swing arm bracket 11, an axially distributed guide rail 12, at least two rubbing plate mounting blocks 13 and at least two filter rubbing plates 6. One end of the swing arm bracket is hinged and the far end is movable. The guide rail is arranged at the movable end of the swing arm bracket, the rubbing plate mounting block is installed on the guide rail, and the rubbing plate is installed on the rubbing plate mounting block.

[0005] Among them, in the working state, the arc surface of the washboard is concentric with the outer cylindrical surface of the offset drum wheel, the washboard mounting block can be used to adjust the radial distance between the washboard and the offset drum wheel, and the guide rail cooperates with the washboard mounting block to adjust the axial and circumferential position of the washboard and the offset drum wheel; in the non-working state, the entire filter washboard mechanism rotates around one end of the swing arm bracket away from the offset drum wheel.

[0006] It can be seen from the above structure that under the dynamic movement of the filter rubbing plate mechanism, the accuracy of the relative offset drum position is difficult to guarantee, so each start-up needs to be calibrated once with a rod sample similar to the filter; during maintenance, the entire filter supply system needs to be dismantled and reinstalled, and after reinstallation, it will take multiple starts, trial production and adjustments to achieve the set accuracy.

[0007] Since the movable parts are not frequently assembled and disassembled, there is no corresponding calibration tooling designed. Generally, manual calibration is performed using a ruler. However, with the continuous improvement of production efficiency and the excessive reliance on manual proficiency, it is necessary to design a tooling to meet the calibration requirements of the filter rubbing plate after reassembly and at startup, so as to improve the calibration efficiency.

[0037] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0039] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] according to Figures 1 to 6 As shown, the utility model provides a positioning tool for a filter rubbing plate 6 of a cigarette assembling machine, comprising an arc plate body 1, an inner positioning rib 2 and an outer positioning protrusion 3;

[0043] The arc surface of the arc plate body 1 is concentric with the arc surface of the offset drum 4 to form an independent arc-shaped buckle plate pattern, which is temporarily assembled with the offset drum 4 .

[0044] The inner positioning ribs 2 are arranged on the inner surface of the arc plate body 1. The distribution of the inner positioning ribs 2 corresponds one-to-one to the distribution of the arc grooves 5 on the offset drum wheel 4. The thickness of the arc plate body 1 is the calibrated thickness. The inner positioning ribs 2 are used to match one-to-one with the arc grooves 5 on the offset drum wheel 4 for positioning during installation.

[0045] The external positioning protrusion 3 is arranged on the outer surface of the arc plate body 1. The external positioning protrusion 3 is a plurality of arc strips parallel to each other that are integrally formed on the outer surface of the arc plate body 1. The spacing distance of the external positioning protrusion 3 matches the theoretical spacing of adjacent filter rubbing plates 6, so that the filter rubbing plates 6 can control the spacing between each other during the installation and adjustment process to complete the axial adjustment.

[0046] Furthermore, the inner positioning rib 2 is integrally formed with the arc plate body 1 or assembled into one with bolts.

[0047] Furthermore, the inner surface of the arc plate body 1 or the inner positioning rib 2 body or the inner positioning rib 2 surface is set as a magnetic material. The two can be fixed by magnetic attraction or adhesive. The present embodiment adopts the magnetic attraction method, and the magnetic attraction material is designed as a magnetic attraction layer set on the inner surface of the arc plate body 1 or the inner positioning rib 2 itself, or the inner positioning rib 2 surface.

[0048] In some embodiments, the two axial ends of the arc plate body 1 are not blocked, and the arc plate body 1 can adjust its axial position relative to the offset drum wheel 4 , so that it can be used in offset drum wheels 4 of different specifications.

[0049] like Figure 6 As shown, in other embodiments, a limit baffle 7 is provided at one end of the arc plate body 1, and an adjusting screw 8 is provided on the limit baffle 7. The end of the adjusting screw 8 abuts against the end face of the offset drum wheel 4 to adjust the distance between the limit baffle 7 and the end face of the offset drum wheel 4.

[0050] Furthermore, a handle is provided at the outer end of the adjustment limit baffle 7 to improve the convenience of operation.

[0051] Furthermore, the axial length of the arc plate body 1 is greater than the axial length of the offset drum wheel 4, the adjustable limit is larger, and the two ends are exposed, which makes it easier to operate and push.

[0052] Furthermore, in order to prevent the tool from being too heavy, the material of the arc plate body 1 is set to be plastic material, which is light and easy to use.

[0053] Furthermore, the arc angle of the arc plate body 1 is between 60° and 180°. The larger the arc angle, the more secure the installation is, but the volume of the tooling also increases accordingly, so it needs to be set according to actual conditions.

[0054] Working process:

[0055] During maintenance or pneumatic calibration, the tooling is first mounted upside down on the surface of the offset drum 4, and the axial position of the tooling is adjusted so that the plurality of external positioning protrusions 3 are located at the set positions.

[0056] Then rotate the offset drum 4 to make the tooling correspond to the adjustment position of the filter rubbing plate 6, and then adjust the filter rubbing plate 6 to the working position. At this time, the tooling is located between the offset drum 4 and the filter rubbing plate 6. Then adjust the movable block of the filter rubbing plate 6 to be close to the outer surface of the arc plate body 1 to achieve radial adjustment. The process of complete fitting achieves circumferential adjustment. At the same time, in the circumferential direction, make each filter rubbing plate 6 close to the outer positioning protrusion 3 to achieve axial adjustment.

[0057] After the adjustment is completed, the offset drum 4 is slowly rotated to completely rotate the tooling out, and then the tooling is removed to complete the calibration process.

[0058] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
