Description

Technical Field

[0001] The utility model relates to the field of cigarette making equipment, and more specifically to a tipping paper supply and pressing device for a YJ27 cigarette maker. Background Art

[0002] The ZJ17 cigarette-making and splicing unit consists of the YJ17 tobacco feeder, the YJ17 tobacco rod forming and rolling machine, and the YJ27 filter splicer. The tipping paper supply system on the YJ27 splicer is an auxiliary process flow for the splicer. After being loaded onto the paper tray, the tipping paper is pulled by the paper feed roller and the pressure roller through the automatic splicer and the tipping paper curler before entering the gluing device. After being coated with glue, it enters the tipping paper cutting wheel, where the cutter cuts the tipping paper into standard sheets. The sheets then enter the gathering drum and merge with the main process flow, where they are glued one by one onto the "cigarette pack." The splicing drum and the washboard work together to splice the sheets into filter cigarettes.

[0003] During actual production, the tipping paper attachment section of filter cigarettes often exhibits quality defects such as air leaks, wrinkles, and warping. To ensure quality, the maintenance team adjusted and modified the attachment machine, adjusting the angle or increasing the number of tipping paper curlers. This ensured that the glued surface of the tipping paper was scraped and curled, ensuring a fully and evenly applied glue, thus preventing these quality defects. However, this measure increased the traction force on the tipping paper, causing the tipping paper feed to slip. The laser perforation glue line shifted, ultimately resulting in a lack of glue at the laser-perforated joint of the tipping paper and warping of the edges. Utility Model Content

[0004] One purpose of the present utility model is to provide a new technical solution for the tipping paper feeding and pressing device of the YJ27 tipping machine, so as to solve the problems raised in the above-mentioned background technology.

[0005] According to a first aspect of the present invention, a tipping paper feeding and pressing device for a YJ27 tipping machine is provided, comprising a cylinder, a pressing roller and a paper feeding roller;

[0006] The cylinder is fixed to the mounting device through a support plate, and the piston rod of the cylinder passes through the support plate and is connected to a connecting seat, and the paper pressing roller is rollingly connected in the connecting seat;

[0007] The paper feed roller is arranged on the connecting machine, and the circumferential surface of the paper feed roller corresponds to the circumferential surface of the paper pressing roller. The tipping paper shuttles between the circumferential surface of the paper feed roller and the circumferential surface of the paper pressing roller. The cylinder can drive the paper pressing roller close to the paper feed roller.

[0008] Optionally, according to the tipping paper supply and pressing device of the YJ27 loader described in the present invention, a protective plate is provided on the outer side of the connecting seat, and the protective plate is fixed on the loader.

[0009] Optionally, according to the YJ27 tipping paper supply and pressing device of the loader described in the present invention, the top of the protective plate extends above the connecting seat, and a base is provided on the upper side of the protective plate, and the support plate is fixed on the base.

[0020] 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.

[0021] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0022] 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 part of the specification.

[0023] 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.

[0024] according to Figure 1 As shown, the utility model provides a YJ27 tipping paper feeding and pressing device for a tipping paper loading machine, comprising a cylinder 3, a pressing roller 7 and a paper feeding roller 8;

[0025] The cylinder 3 is fixed to the mounting device through the support plate 5, and the piston rod of the cylinder 3 passes through the support plate 5 and is connected to the connecting seat, and the paper pressing roller 7 is rollingly connected in the connecting seat;

[0026] The paper feed roller 8 is arranged on the connecting machine, and the circumferential surface of the paper feed roller 8 corresponds to the circumferential surface of the paper pressing roller 7. The tipping paper shuttles between the circumferential surface of the paper feed roller 8 and the circumferential surface of the paper pressing roller 7. The cylinder 3 can drive the paper pressing roller 7 to be close to the paper feed roller 8.

[0027] When the machine is started, the PLC electronic control system uses the electromagnetic valve to make the compressed air push the piston rod of the cylinder 3, and the piston rod drives the connecting seat to push the paper pressing roller 7. Because the working pressure of the cylinder 3 is stable and the pressure size is controllable, the cylinder 3 is pressurized to apply a constant pressure to the paper pressing roller 7. At the same time, the pressure spring in the original tipping paper rack also applies a certain pressure to the tipping paper pressure roller 7. Under the action of double pressure, the friction between the paper pressing roller 7 and the paper supply roller 8 is increased to prevent the tipping paper from slipping, thereby eliminating the quality defects of the tipping paper laser punching glue line movement, the tipping paper overlap laser punching without glue, and the warping edge.

[0028] Furthermore, a protective plate 9 is provided on the outer side of the connecting seat, and the protective plate 9 is fixed on the connecting machine.

[0029] The top of the protective plate 9 extends above the connecting seat, and a base is provided on the upper side of the protective plate 9, and the support plate 5 is fixed on the base. In this embodiment, the protective plate 9 is located outside the paper pressing roller 7 and has an overall L-shaped structure to protect the paper pressing roller 7.

[0030] Furthermore, the two ends of the connecting base are provided with an upwardly extending front pressure plate 1 and rear pressure plate 2. A connecting plate 4 is provided between the tops of the front pressure plate 1 and the rear pressure plate 2. The connecting plate 4 is connected to the piston rod of the cylinder 3. During operation, the front pressure plate 1 and the rear pressure plate 2 are respectively connected to the two ends of the connecting base, thereby driving the paper pressing roller 7 to move downward as a whole, ensuring uniform contact between the paper pressing roller 7 and the paper feed roller 8, and preventing the tipping paper from being subjected to uneven pressure from the paper pressing roller 7 and the paper feed roller 8.

[0031] Furthermore, downwardly extending roller frames 6 are provided at both ends of the connecting base, and the roller shafts at both ends of the pressure roller 7 are rollingly connected to the roller frames 6. There are two pressure rollers 7, symmetrically arranged in the roller frames 6, centered around the axis of the feed roller 8. In operation, the two pressure rollers 7 press the tipping paper against the feed roller 8, thereby increasing the contact area between the tipping paper and the feed roller 8, ensuring that the feed roller 8 effectively drives the tipping paper.

[0032] Furthermore, the roller frame 6 is provided with an axial hole for connecting the paper pressing roller 7, and the side wall of the axial hole is provided with a slot extending outside the roller frame 6. The bottom of the roller frame 6 is provided with an adjusting bolt 10 passing through the slot, and the adjusting bolt 10 is used to adjust the width of the slot to adjust the diameter of the axial hole.

[0033] In this embodiment, the diameter of the shaft hole is slightly larger than the diameter of the roller shaft of the paper pressing roller 7, so that the paper pressing roller 7 can be easily installed in the roller frame 6. The width of the slot is adjusted by tightening and loosening the adjusting bolt 10. The two ends of the slot are an integrated structure with the shaft hole, so that the change of the slot can directly affect the change in the diameter of the shaft hole, thereby adjusting the rotational friction coefficient between the paper pressing roller 7 and the roller frame 6 to prevent the paper pressing roller 7 and the paper feed roller 8 from being too tight or too loose, which may cause the paper pressing roller 7 to be unable to rotate effectively or the tipping paper to slip.

[0034] This utility model, through the application of pressure by the air cylinder 3, completely eliminates the problem of the laser-punched fish glue line moving, which can cause problems such as a lack of glue and warping at the laser-punched holes in the tipping paper overlap. This ensures the quality of the tipping paper splices on filter cigarettes and eliminates the quality defects caused by a lack of glue and warping at the laser-punched holes in the tipping paper overlap. This improves product quality and reduces material consumption caused by the lack of glue and warping at the laser-punched holes in the tipping paper overlap.

[0035] 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.
