Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a paper feeding guide device. Background Technology

[0002] Tipping paper is a crucial material in cigarette production, used to attach cigarette packs and filters during the cigarette manufacturing process. Before tipping, the tipping paper undergoes processes such as rolling, positioning, gluing, preheating, and cutting to ensure uniform size and correct positioning for the tipping operation. Correct positioning prevents problems such as curled edges, crooked or uneven cuts, misaligned cigarette lengths, air leakage, and glue sticking in areas without glue. To guarantee effective tipping, the tipping machine employs a tipping paper guide device for precise positioning.

[0003] The existing tipping paper guiding device consists of two symmetrically designed tipping paper guide blocks and a hollow shaft. The two tipping paper guide blocks are fastened to the hollow shaft with locking screws. Each tipping paper guide block has a separate integrated component with a tipping paper support surface and a guide surface. The guidance and support of the tipping paper are completed by the combination of the two tipping paper guide blocks. The hollow shaft is fitted onto the support shaft of the paper guiding device, and the support shaft is fastened to the wall panel with a locking nut. A locating pin is provided on the hollow shaft to prevent it from rotating along the support shaft. When it is necessary to change the tipping paper specification, the fastening screws of the two tipping paper guide blocks are loosened, and the two tipping paper guide blocks are separated or joined axially.

[0004] When the same equipment produces multiple brands of cigarettes, the specifications of the tipping paper (usually referring to the width of the tipping paper) often change. This requires frequent adjustments to the tipping paper guide blocks of the tipping machine, which can easily lead to problems such as: if the left and right guide blocks are separated too much, the center separation position of the tipping paper guide blocks will be concave, causing wrinkles, misalignment, and bubbles in the tipping paper; the guide blocks are easily rotated when adjusted independently relative to the hollow shaft, causing unstable tipping paper operation, long adjustment time, and material waste.

[0005] Therefore, how to provide a paper feeding guide device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] One objective of this invention is to provide a new technical solution for a paper feeding and guiding device.

[0007] According to a first aspect of the present invention, a paper feeding guide device is provided, comprising: a paper guide block, an adjustment component, and a rotation component;

[0026] 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 arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figures 1 to 4 As shown, this utility model embodiment provides a paper feeding guide device, including: a paper guide block 1, an adjustment component 2, and a rotation component 3.

[0031] The adjusting assembly 2 includes two limiting plates 21, multiple fixing holes 22, and fastening bolts 23. The multiple fixing holes 22 are respectively located at both ends and both sides of the paper guide block 1. The fastening bolts 23 pass through the limiting plates 21 and the fixing holes 22 to fix the limiting plates 21 onto the paper guide block 1. Specifically, there are eight fixing holes 22, which are respectively located at the four corners of the paper guide block 1, with each pair of fixing holes 22 forming a group.

[0032] The rotating component 3 is connected to the paper guide block 1 and is used to drive the paper guide block 1 to rotate axially.

[0033] Specifically, when the cigarette machine needs to change the distance between the two limit plates 21 by changing the tipping paper, the operator can adjust the fastening bolts 23 in different fixing holes 22, thereby increasing or decreasing the distance between the two limit plates 21 to accommodate tipping paper of different specifications, so that the guide block 1 can transport tipping paper of different specifications.

[0034] Furthermore, the paper guide block 1 of this utility model eliminates the support structure in the middle of the splicing paper, and solves the problems of wrinkles, length discrepancies, and unstable operation of the splicing paper caused by the different arc surfaces of the left and right paper guide blocks 1 in the prior art.

[0035] This invention features multiple fixing holes 22 respectively located at both ends and sides of the paper guide block 1, with fastening bolts 23 penetrating the limiting plate 21 and fixing holes 22, thereby fixing the limiting plate 21 onto the paper guide block 1 and connecting the rotating assembly 3 to the paper guide block 1. In use, the operator first moves the limiting plates 21 at both ends of the paper guide block 1 according to the specifications of the receiving paper, ensuring the distance between the two limiting plates 21 equals the size of the receiving paper. This adjustment of the limiting plate 21 positions allows the paper guide block 1 to transport paper guide blocks of different specifications, reducing the number of defective products generated during adjustment, saving adjustment time, reducing the consumption of cigarette raw materials and auxiliary materials, and lowering spare parts costs. It also eliminates the problems and quality risks of the original paper guide device, improving the effective operating rate of the equipment.

[0036] In one embodiment of the paper feeding guide device of this utility model, such as Figure 2 As shown, scale lines 4 are provided on the side wall of the paper guide block 1. This design allows for accurate adjustment of the position of the limit block.

[0037] In one embodiment of the paper feeding guide device of this utility model, such as Figure 1 and Figure 4 As shown, the adjustment component 2 also includes waist-shaped holes 24, which are respectively disposed on both ends of the limiting plate 21.

[0038] Specifically, when it is necessary to change the distance between the two limiting plates 21, the operator can adjust the position of the fastening bolt 23 in the waist-shaped hole 24, thereby increasing or decreasing the distance between the two limiting plates 21, realizing the rapid adjustment of the axial guidance of the paper splicing, saving time and material consumption caused by changing the splicing paper specifications.

[0039] It should be noted that this method only allows for fine-tuning of the distance between the two limiting plates 21. When the required displacement is large, it is necessary to adjust the fastening bolts 23 by placing them in different fixing holes 22.

[0040] Furthermore, the waist-shaped hole 24 extends along the width direction of the limiting plate 21.

[0041] In one embodiment of the paper feeding guide device of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the adjustment component 2 also includes a slide groove 25 and a moving block 26. The moving block 26 is disposed on the inner wall of the limiting plate 21. The slide groove 25 is disposed on both ends of the paper guide block 1 and extends along the length direction of the paper guide block 1. The slide groove 25 is located in the middle position of the paper guide block 1. The moving block 26 is slidably disposed in the slide groove 25.

[0042] This invention improves the guiding and limiting effect of the movement of the limiting block by setting the movable block 26 on the inner wall of the limiting plate 21, setting the sliding groove 25 on both ends of the paper guide block 1 and extending along the length of the paper guide block 1, and positioning the sliding groove 25 in the middle of the paper guide block 1. The movable block 26 is slidably set in the sliding groove 25. Through the cooperation of the movable block 26 and the sliding groove 25, the movement of the limiting block is improved, and the stability of the movement of the limiting block is increased.

[0043] In one embodiment of the paper feeding guide device of this utility model, such as Figure 2 and Figure 4As shown, the adjustment component 2 also includes a fixing block 27 and a connecting groove 28. The connecting groove 28 is disposed on the two side walls of the paper guide block 1, and the fixing block 27 is disposed on both ends of the limiting plate 21. The fixing block 27 is disposed in the connecting groove 28.

[0044] This utility model improves the stability of installation by setting the connecting groove 28 on the two side walls of the paper guide block 1 and setting the fixing blocks 27 on both ends of the limiting plate 21. The fixing blocks 27 are set in the connecting groove 28, that is, the limiting plate 21 is locked in the connecting groove 28 on both sides of the paper guide block 1 by the two fixing blocks 27.

[0045] In one embodiment of the paper feeding guide device of this utility model, such as Figure 1 and Figure 2 As shown, a connecting hole 11 is provided in the center of the paper guide block 1.

[0046] The rotating assembly 3 includes a knurled knob 31, a first connecting block 32, and a second connecting block. The first end of the knurled knob 31 is connected to the connecting hole 11. The first connecting block 32 is disposed at the first end of the knurled knob 31 and abuts against the end of the paper guide block 1.

[0047] This utility model connects the first end of the knurled knob 31 to the connecting hole 11, sets the first connecting block 32 at the first end of the knurled knob 31 and abuts against the end of the paper guide block 1, and sleeves the second connecting block 33 on the second end of the knurled knob 31, thereby causing the knurled knob 31 to drive the paper guide block 1 to rotate, so as to achieve fine adjustment of the position of the paper guide block 1.

[0048] In one embodiment of the paper feeding guide device of this utility model, such as Figure 1 and Figure 2 As shown, the rotating assembly 3 also includes a limiting post 34 and a mounting hole 35. The mounting hole 35 is located at the bottom of the paper guide block 1 and communicates with the connecting hole 11.
