Description

Technical Field

[0001] This invention relates to the field of tipping paper, and more specifically to a tipping paper guiding device. Background Technology

[0002] The ZJ17 cigarette-making equipment's tipping paper guide rail consists of a guide block, two M5 locking screws, and a sleeve. Its function is to adjust the inward and outward position of the tipping paper, ensuring it is centered twice the size of the cigarette. The adjustment requirements are: the center of the tipping paper guide rail should be 205mm from the machine base, and the distance between the guide rail's limiting groove and the tipping paper width plus 0.5mm. Incorrect adjustment of the tipping paper guide rail significantly impacts cigarette quality (e.g., tipping paper length discrepancies, wrinkles, and burrs, etc., resulting in Class B and Class C quality defects). Since different cigarette brands require tipping paper of varying widths, the warehouse needs to store a large number and variety of guide blocks, increasing spare parts costs and affecting equipment operating efficiency during parts retrieval.

[0003] Due to the personalization and diversification of cigarette design, the design of tipping paper has also become very diverse. During the production process, the printed surface of the tipping paper may have poor water absorption due to special treatment or design requirements. In addition, the differences between different manufacturers and batches have a significant impact on the splicing quality of cigarettes, consumption per carton, and equipment operation. Maintenance personnel need to frequently and repeatedly adjust the equipment to adapt to different tipping papers.

[0004] Based on the on-site investigation, there is ample space near the tipping paper guide rail. It is proposed to design a tipping paper guiding device in combination with the structural dimensions of the tipping paper guide rail and the tipping paper bending process to improve the quality of cigarette products, reduce spare parts inventory, and improve equipment operating efficiency.

[0005] like Figure 1 As shown, the tipping paper guide rail is located in the transmission path between the paper feeding roller and the gluing device. The inward and outward positions of the tipping paper are adjusted by the combined action of the adjusting rod and the compression spring, and guided by the pin connection between the sleeve and the adjusting rod. The adjustment requirements for the tipping paper guide rail are as follows: the center of the tipping paper guide rail should be 205mm from the machine base, adjusted by manually rotating the adjusting rod; the distance between the limit grooves of the tipping paper guide rail should be the width of the tipping paper plus 0.5mm, determined according to the product specifications. The guide block must be replaced each time the paper size is changed.

[0006] The tipping paper guide rail consists of a paper guide block, two M5 screws, and a sleeve. The paper guide block is fixed to the sleeve by the two M5 screws, and the sleeve is fixed to the adjusting rod. When the tipping paper guide rail is correctly adjusted, the tipping paper is in the overlapping position in the middle of the double cigarette, that is, the tipping paper is in the correct overlapping position.

[0007] The following problems exist with the tipping paper guide rail: ① High replacement frequency of the tipping paper guide rail. Because the required width and length of tipping paper vary for each type of cigarette product; and the tipping paper guide rail is related to the cigarette brand specifications, the guide rail must be replaced every time the brand is changed, resulting in a large workload. (Common tipping paper widths are 60mm, 64mm, 70mm, 72mm, etc., and the number of brand changes reaches more than ten times per month.)

[0008] ② The quantity of spare parts for cork paper guide rails is large. Since each set of equipment and each type of specification requires a paper guide block, the quantity of spare parts in the warehouse is large and the cost of spare parts is high.

[0009] ③ The tipping paper guide rail has a single function. Since the tipping paper guide rail only plays the role of guiding the tipping paper in the winding and splicing equipment, it has a simple structure and a single function. Summary of the Invention

[0010] This invention provides a tipping paper guiding device to solve the problems in the background art.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A tipping paper guiding device includes: a first guide rail having a first arc-shaped guide groove; a second guide rail having a second arc-shaped guide groove; a sleeve having the first and second guide rails slidably fitted onto the sleeve, such that the first and second arc-shaped guide grooves are arranged opposite to each other; and a scraper having the scraper disposed on the first and second guide rails for scraping the tipping paper on the first and second arc-shaped guide grooves.

[0013] Furthermore, the sleeve is provided with scale lines.

[0014] Furthermore, a first positioning groove is provided on the side wall of the first guide rail, and a second positioning groove is provided on the side wall of the second guide rail. The scraper is limited by the first positioning groove and the second positioning groove, and is fixed on the side wall of the first guide rail and the second guide rail by the arc-shaped pressure plate.

[0015] Furthermore, the cross-section of the first guide rail is fan-shaped with a central angle of 90°, and the first positioning groove is formed on the side wall of the first guide rail corresponding to the 45° central angle; the cross-section of the second guide rail is fan-shaped with a central angle of 90°, and the second positioning groove is formed on the side wall of the second guide rail corresponding to the 45° central angle.

[0016] The beneficial effects of this invention compared to the prior art are:

[0017] By applying the tipping paper guiding device provided by this invention, it was found that the tipping paper guiding function is normal, replacement and adjustment are convenient, the cigarette splicing quality is good, and the equipment production efficiency is greatly improved. This design not only optimizes the adjustment method of the tipping paper guide rail, but also solves the time-consuming problem of frequently replacing the tipping paper guide rail.

[0018] The technical solution of this invention incorporates a doctor blade, which further roughens the surface of the tipping paper, increasing its absorbency and improving the adhesion between the tipping paper and the printed surface. This, in turn, improves the quality of cigarette splicing and the stability of equipment operation, while also reducing energy consumption. No adjustments or parameter changes are required when using tipping paper from different manufacturers or from different batches of the same manufacturer. The splicing quality is significantly improved, resulting in enhanced quality, reduced energy consumption, increased equipment operating efficiency, and lower spare parts costs and operator workload.

[0022] Figure 4 This is a schematic diagram of the assembly of the sleeve, the first guide rail, and the second guide rail of a tipping paper guiding device according to the present invention.

[0023] The markings in the diagram are: 1-first guide rail, 2-arc pressure plate, 3-sleeve, 4-scraper, 5-second guide rail, 6-second arc guide groove, 7-first arc guide groove, 8-second positioning groove, 9-first positioning groove. Detailed Implementation

[0024] like Figure 3 As shown, a tipping paper guiding device includes: a first guide rail 1, on which a first arc-shaped guide groove 7 is formed; a second guide rail 5, on which a second arc-shaped guide groove 6 is formed; a sleeve 3, on which the first guide rail 1 and the second guide rail 5 are slidably sleeved, such that the first arc-shaped guide groove 7 and the second arc-shaped guide groove 6 are arranged opposite to each other; and a scraper 4, which is disposed on the first guide rail 1 and the second guide rail 5, for scraping the tipping paper on the first arc-shaped guide groove 7 and the second arc-shaped guide groove 6.

[0025] Because the original tipping paper guide rail was a single integrated paper guide block, such as Figure 2As shown, it is designed with two adjustable paper guide blocks, namely the first guide rail 1 and the second guide rail 5. This solves the problem of limited equipment space and facilitates installation. On the other hand, the adjustable paper guide blocks reduce spare parts costs and inventory. The first guide rail 1 and the second guide rail 5 can slide simultaneously on the sleeve 3, thereby meeting the guiding requirements of tipping paper of different widths.

[0026] To ensure the separation distance between the two guide blocks meets the requirement (tip paper width + 0.5mm), we designed a scale on sleeve 3 that expands outwards from the center line. The sleeve 3 is equipped with scale lines.

[0027] like Figure 4 The sleeve 3 is marked with graduations, where A = tipping paper width + 0.5mm, B = 30.25mm, and 2B = 60.5mm. This means that when the two guide blocks are fitted and locked together, the width of the tipping paper guide rail is 30.25 x 2 = 60.5mm, suitable for tipping paper with a width of 60mm. Each small division in the graduations is 1mm, and each large division is 5mm. To ensure the tipping paper guide device remains centered, both guide blocks need to be moved simultaneously to the left and right. When the desired graduation is reached, the two locking screws secure the device.

[0028] In this embodiment, a first positioning groove 9 is formed on the side wall of the first guide rail 1, and a second positioning groove 8 is formed on the side wall of the second guide rail 5. The scraper 4 is limited by the first positioning groove 9 and the second positioning groove 8, and is fixed to the side walls of the first guide rail 1 and the second guide rail 5 by the arc-shaped pressure plate 2. The cross-section of the first guide rail 1 is a fan shape with a central angle of 90°, and the first positioning groove 9 is formed on the side wall of the first guide rail 1 corresponding to a central angle of 45°. The cross-section of the second guide rail 5 is a fan shape with a central angle of 90°, and the second positioning groove 8 is formed on the side wall of the second guide rail 5 corresponding to a central angle of 45°.

[0029] This invention designs a secondary texturing device, namely a scraper 4, for the tipping paper in a cigarette machine, aiming to solve the problem that existing pre-texturing devices cannot adapt to different tipping papers. By measuring the relevant dimensions of the two guide rails and considering the transmission direction of the tipping paper, a ceramic scraper 4 is designed on the two guide rails to perform secondary bending and texturing on the tipping paper during operation. This facilitates subsequent gluing and splicing of the tipping paper, improves the quality of cigarette splicing, and reduces tipping paper wrinkling and cigarette air leakage.

[0030] Since the tipping paper is furthest away at 45° on the guide rail (where the roughening effect is best), in order to bend the tipping paper and fully roughen it, the groove of the ceramic scraper 4 is located at 45° on the front and rear guide rails, at the center of the pressure plate.

[0031] It should be noted that the scraper 4 is fixed by a pressure plate, and the pressure plate is fixed to the first guide rail 1 and the second guide rail 5 by screws. The screws that fix the pressure plate also serve to fix the first guide rail 1 and the second guide rail 5, that is, to lock the first guide rail 1 and the second guide rail 5 onto the sleeve 3.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
