Description

Technical Field

[0001] This invention relates to a paper feeding device, and more particularly to a paper feeding and curling device for a ZJ17 feeding and loading machine, belonging to the technical field of tobacco processing equipment. Background Technology

[0002] The function of the feed roller of the ZJ17 feeder is to pull the tipped paper out of the paper tray support and run it at a certain speed. The tipped paper passes through the feed roller and is pressed by the pressure roller. The friction between the feed roller and the tipped paper drives the tipped paper to be conveyed, so as to achieve continuous and uniform paper feeding.

[0003] like Figure 4 As shown, two rubber pressure rollers 100 are mounted on a bracket 101. An eccentric shaft is located within the bracket 101. Rotating the handle 103 lifts the two pressure rollers 100, disengaging them from the feed roller 102. A microswitch is installed on the upper part of the feed roller 102. The feed roller 102 must be replaced promptly after its diameter wears down. The existing mechanism of the feed roller 102's engagement with the rubber pressure rollers 100 results in very rapid wear of the feed roller 102, necessitating periodic replacement.

[0004] In addition, the ZJ17 splicing machine is also equipped with a tipping paper curler. The main function of the tipping paper curler is to curl the tipping paper in operation using a ceramic scraper, thereby improving the quality and stability of misjoining when tipping paper is misjoined.

[0005] Existing tipping paper curlers such as Figure 5 As shown, when the curler enters the working position: solenoid valve 104 opens and the exhaust port closes. Compressed air enters cylinder 107 from above through the first hose 105, causing the curler to move towards the coated surface of the tipping paper. After adjusting the speed at which the curler moves towards the tipping paper, there should be no breakage of the tipping paper. When the curler disengages from the working position: solenoid valve 104 closes to cut off the air from the first hose 105, and the exhaust port of solenoid valve 104 opens. Compressed air flows into cylinder 107 from below through the second hose 106. The air in the upper part of cylinder 107 escapes, and the curler quickly rotates to the non-working position.

[0006] The existing cigarette rolling device is not only complex in structure, but the ceramic scraper of the rolling device also wears out quickly and needs to be replaced regularly. Otherwise, it will cause cigarette quality defects such as curling of the tipping paper and air leakage. If the flipping mechanism fails, the ceramic scraper will not flip or will flip too fast or too slow, which will cause quality problems such as misjoining of the tipping paper. Summary of the Invention

[0007] The purpose of this invention is to provide a paper feeding and curling device for the ZJ17 feeder to solve the technical problems in the prior art. It can both transport and curl the tipped paper, and has the advantages of long service life and no need for frequent replacement, thereby improving production efficiency and reducing production costs.

[0008] This invention provides a paper feeding and curling device for a ZJ17 feeder, comprising a negative pressure suction stator, a mesh-type paper feeding roller, and a compressed air air knife curler. The compressed air air knife curler is fixed inside the negative pressure suction stator, which is installed inside the mesh-type paper feeding roller. A connecting pipe on the negative pressure suction stator passes through the side wall of one end of the mesh-type paper feeding roller and is connected to a negative pressure device. One end of the mesh-type paper feeding roller is connected to a drive device.

[0009] In the aforementioned ZJ17 paper feeding and curling device for the feeder, preferably, the negative pressure suction stator is a cylindrical structure, and a negative pressure cavity is formed inside the negative pressure suction stator. The connecting pipe is fixed at one end of the negative pressure suction stator, and the two are coaxially arranged. The connecting pipe communicates with the negative pressure cavity inside the negative pressure suction stator.

[0010] In the aforementioned ZJ17 paper feeding and winding device, preferably, an opening is provided on the side wall of the negative pressure suction stator.

[0011] In the aforementioned ZJ17 feeder paper curling device, preferably, both ends of the compressed air air knife curler are fixedly connected to the inner walls of both ends of the negative pressure suction stator. The compressed air air knife curler is located in the middle of the opening. An exhaust hole is opened on the top surface of the compressed air air knife curler. One end of the compressed air air knife curler is connected to an air inlet pipe. One end of the air inlet pipe extends to the mesh-type paper feed roller through the connecting pipe. The air inlet pipe is connected to an air compressor.

[0012] In the aforementioned ZJ17 paper feeding and curling device, preferably, the cross-sectional shape of the compressed air air knife curler is an isosceles trapezoid with a smaller top and a larger bottom.

[0013] In the aforementioned ZJ17 feeder paper curling device, preferably, the perforated paper feed roller has a cylindrical structure, and several rows of through holes are evenly distributed on the side wall of the perforated paper feed roller. Each row of through holes is arranged along the axial direction of the perforated paper feed roller. One end of the perforated paper feed roller is detachably fitted with an end cap, and the other end of the perforated paper feed roller has an end plate. The end plate has a paper feed roller mounting hole, and the center of the end plate has a connecting pipe mounting hole.

[0014] Compared with existing technologies, this invention includes a negative pressure suction stator, a mesh-type paper feed roller, and a compressed air air knife curler. The compressed air air knife curler is fixed inside the negative pressure suction stator, which is installed inside the mesh-type paper feed roller. A connecting pipe on the negative pressure suction stator passes through the side wall of one end of the mesh-type paper feed roller and is connected to the negative pressure equipment. One end of the mesh-type paper feed roller is connected to the drive device. This invention uses a fixed negative pressure suction stator and a rotating mesh-type paper feed roller to adsorb and drive the tipping paper. It replaces the original tipping paper pressing roller's function of using pressure to cooperate with the paper feed roller to drive the tipping paper. The curler is designed as a compressed air air knife curler, using a high-pressure air jet to curl the tipping paper. This avoids quality problems such as tipping paper cutting caused by malfunctions in the paper feed mechanism and the curler mechanism, improving product quality and maintenance efficiency.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Embodiments of the present invention: such as Figure 1 , Figure 2 and Figure 3As shown, a paper feeding and curling device for a ZJ17 feeder includes a negative pressure suction stator 1, a mesh-type paper feeding roller 2, and a compressed air air knife curler 3. The compressed air air knife curler 3 is fixed inside the negative pressure suction stator 1. The negative pressure suction stator 1 is installed inside the mesh-type paper feeding roller 2. A connecting pipe 4 on the negative pressure suction stator 1 passes through the side wall of one end of the mesh-type paper feeding roller 2. The connecting pipe 4 is connected to a negative pressure device. One end of the mesh-type paper feeding roller 2 is connected to a drive device.

[0023] During operation, the negative pressure suction stator 1, connected to the negative pressure equipment, remains stationary. Under the action of the negative pressure equipment, negative pressure is generated on the surfaces of the negative pressure suction stator 1 and the mesh-type paper feed roller 2, achieving adsorption of the tipped paper. The mesh-type paper feed roller 2, connected to the drive device, rotates continuously, realizing the conveying of the tipped paper. Compared with existing technologies, this structure not only achieves the conveying of tipped paper but also greatly simplifies the structure and solves the problem of rapid wear of traditional rubber pressure rollers. High-pressure air is introduced into the compressed air air knife curler 3. The high-pressure air blown out by the compressed air air knife curler 3 can achieve the curling of the tipped paper, making the structure simpler than existing technologies.

[0024] In one specific embodiment, the negative pressure suction stator 1 has a cylindrical structure and a negative pressure cavity is formed inside the negative pressure suction stator 1. The connecting pipe 4 is fixed at one end of the negative pressure suction stator 1 and is coaxially arranged with the negative pressure suction stator 1. The connecting pipe 4 communicates with the negative pressure cavity inside the negative pressure suction stator 1.

[0025] The connecting pipe 4 is fixed to the negative pressure device. The negative pressure device is existing technology, and its structure will not be described in detail. The negative pressure device forms negative pressure in the negative pressure cavity of the negative pressure suction stator 1 through the connecting pipe 4.

[0026] Furthermore, the mesh-type paper feed roller 2 has a cylindrical structure. Several rows of through holes 8 are evenly distributed on the sidewall of the mesh-type paper feed roller 2, with each row of through holes 8 arranged along the axial direction of the mesh-type paper feed roller 2. One end of the mesh-type paper feed roller 2 is detachably fitted with an end cap 9, which can be connected by snap-fit ​​or screws. The other end of the mesh-type paper feed roller 2 has an end plate 10, on which a paper feed roller mounting hole 11 is opened. A connecting pipe mounting hole 12 is opened at the center of the end plate 10. The paper feed roller mounting hole 11 is used for fixed connection between the end plate 10 and the drive device. The connecting pipe mounting hole 12 is used for the connecting pipe 4 to pass through. The diameter of the connecting pipe mounting hole 12 is slightly larger than the outer diameter of the connecting pipe 4, thereby ensuring that the mesh-type paper feed roller 2 can rotate smoothly. An opening 5 is opened on the sidewall of the negative pressure suction stator 1. The length of the opening 5 is less than the length of the negative pressure suction stator 1, and the width of the opening 5 is equal to the diameter of the negative pressure suction stator 1.

[0027] The cross-sectional shape of both ends of the negative pressure suction stator 1 is circular, and the cross-sectional shape of the opening 5 area is semi-circular. The opening 5 area coincides with the path of the tipping paper as it adheres to the mesh feed roller 2, ensuring that the tipping paper can be firmly adsorbed by the negative pressure in the stator when running on the mesh feed roller 2.

[0028] Furthermore, the two ends of the compressed air air knife curler 3 are fixedly connected to the inner walls of the two ends of the negative pressure suction stator 1. The compressed air air knife curler 3 is located in the middle of the opening 5. An exhaust port 6 is opened on the top surface of the compressed air air knife curler 3. One end of the compressed air air knife curler 3 is connected to an air inlet pipe 7. One end of the air inlet pipe 7 extends to the mesh-type paper feed roller 2 through a connecting pipe 4. The air inlet pipe 7 is connected to an air compressor, and an air inlet solenoid valve is installed on the connecting pipe between the two. The cross-sectional shape of the compressed air air knife curler 3 is an isosceles trapezoid with a smaller top and a larger bottom.

[0029] The working principle of this invention is as follows: During operation, the negative pressure device draws air from the negative pressure suction stator 1 through the connecting pipe 4, creating a negative pressure in the negative pressure chamber of the negative pressure suction stator 1. The negative pressure suction stator 1 remains stationary during operation. The mesh-type paper feed roller 2 rotates at a uniform speed under the drive of the driving device. When the mesh-type paper feed roller 2 rotates, its through-hole 8 rotates to the opening 5 area on the negative pressure suction stator 1, creating a negative pressure on the surface of the through-hole 8. This causes the mesh-type paper feed roller 2 to adhere to the tipping paper, thus conveying the tipping paper. When it is necessary to curl the tipping paper, the air inlet solenoid valve is opened, and high-pressure air enters the compressed air air knife curler 3 through the air inlet pipe 7 and is ejected through the air outlet 6 at its top, forming a row of air knives. These air knives apply non-contact blowing pressure to the working surface of the tipping paper running on the mesh-type paper feed roller 2, causing the working surface of the tipping paper to bend and deform into a curl.

[0030] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures.
