[0023] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] This utility model provides a paper feeding and slitting device, including a cutting blade, a cutting blade shaft, a cutting blade holder, a paper cutting roller, a paper pressing roller, and a pneumatic component. The cutting blade shaft and the paper pressing roller are mounted on the cutting blade holder and are located on opposite sides above the paper cutting roller. The cutting blade is fixedly mounted on the cutting blade shaft. The paper cutting roller has a cutting blade groove corresponding to the cutting blade. The pneumatic component is fixedly connected to the cutting blade holder and is used to drive the cutting blade holder to move up and down. The cutting blade of the tipping paper slitting device, in conjunction with the cutting groove of the cutting roller, can slit the tipping paper. The cutting roller, in conjunction with the pressure roller, can convey the tipping paper. When the tipping paper slitting device is applied to tipping paper rolling equipment, it can simultaneously undertake the functions of tipping paper slitting and tipping paper conveying, thereby reducing the number of parts in the tipping paper rolling equipment. During the production process, it can shorten the travel path of the tipping paper, reduce the phenomenon of tipping paper shaking and deviation caused by excessively long paths, and further reduce the phenomenon of tipping paper strip flipping and cigarette air leakage, thereby improving product yield and production efficiency.

[0025] like Figure 2-4 As shown, in one embodiment of this utility model, the paper feeding and slitting device 3 includes a cutting blade 31, a cutting blade shaft 32, a cutting blade holder 33, a paper cutting roller 34, a paper pressing roller 35, and a pneumatic component 36. The cutting blade shaft 32 and the paper pressing roller 35 are mounted on the cutting blade holder 33 and are located on both sides above the paper cutting roller 34. The cutting blade 31 is fixedly mounted on the cutting blade shaft 32. The paper cutting roller 34 has a cutting blade groove 341 corresponding to the cutting blade 31. The pneumatic component 36 is fixedly connected to the cutting blade holder 33 to drive the cutting blade holder 33 to move up and down. The splicing paper slitting device 3 also includes a motor, which is connected to the paper cutting roller 34 via a belt or chain. When slitting the splicing paper, the cutting blade 31 is placed in the cutting blade groove 34 and abuts against the bottom of the cutting blade groove 34. The surface of the paper pressing roller 35 abuts against the surface of the paper cutting roller 34. The motor drives the paper cutting roller 34 to rotate, and the rotation of the paper cutting roller 34 drives the cutting blade 31 to rotate, thus slitting the splicing paper by shearing. At the same time, the rotation of the paper cutting roller 34 drives the rotation of the paper pressing roller 35, and the splicing paper strip obtained after slitting is conveyed to the rear end.

[0026] The cutting blade holder 33 includes a crossbeam 331 and two side plates 332 corresponding to both ends of the crossbeam 331. The cutting blade shaft 32 and the paper pressure roller 35 are mounted on the two side plates 332 via bearings. The pneumatic component 36 includes a mounting base 361, a cylinder 362 fixedly mounted on the mounting base 361, and a mounting plate 363 connected to the end of the cylinder telescopic rod. The mounting plate 363 is fixedly connected to the crossbeam 331 of the cutting blade holder 33. The pneumatic element 36, with the operator selecting a suitable air pressure, drives the cutting blade holder 33 to move up and down. The up and down movement of the cutting blade holder 33 drives the cutting blade shaft 32 to move up and down, performing forward and backward cutting motion on the cutting blade 31. At the same time, the up and down movement of the cutting blade holder 33 drives the paper pressure roller 35 to move up and down. The paper cutting roller 34 and the paper pressure roller 35 cooperate to convey the paper to be loaded. By selecting a suitable air pressure, it is possible to prevent paper slippage due to insufficient air pressure causing insufficient friction between the paper to be loaded and the paper pressure roller 35, or paper blockage due to excessive air pressure causing excessive friction between the paper to be loaded and the paper pressure roller 35.

[0027] A cutting blade holder 311 is fixedly mounted on the cutting blade shaft 32, and the cutting blade 31 is fixedly connected to the cutting blade holder 311 via a retaining spring 312. A spring seat 381 is also fixedly mounted on the cutting blade shaft 32, and a spring 38 is sleeved on the cutting blade shaft 32. One end of the spring 38 abuts against the spring seat 381, and the other end of the spring 38 abuts against the side plate 332. A slanted block 37 is provided at the end of the cutting blade shaft 32 away from the spring 38, and the end of the cutting blade shaft 32 abuts against the slanted block 37. The slanted block 37 is wider at the top and narrower at the bottom than the side closest to the cutting blade shaft 32, forming a slanted surface. The cutting blade 31 is axially positioned by the spring 38 and the slanted block 37, and circumferentially positioned by the cutting blade holder 311 and the retaining spring 312, and cooperates with the cutting groove 341 of the paper cutting roller 34 to perform the cutting motion of the loaded paper.

[0028] The tipping paper slitting device can be applied to tipping paper roll packaging equipment, such as... Figure 5 As shown, the tipping paper roll packaging equipment includes a tipping paper slitting device 3, a glue coating roller 4, a heater 5, a paper cutting roller 6, a knife roller 7, and a converging roller 8. The tipping paper slitting device 3 employs... Figure 2-4 The tipping paper slitting device in the illustrated embodiment. During production, the cutting blade 31 of the tipping paper slitting device cooperates with the cutting groove 341 of the cutting roller 34 to slit the tipping paper, and the cutting roller 34 cooperates with the pressure roller 35 to convey the tipping paper. The specific working process is as follows:

[0029] The feed paper enters from the side of the cutter 31 and exits from the side of the pressure roller 35. When the feed paper passes by, the pneumatic component 36 pressurizes to the pressure set for the feed action, driving the cutter holder 33 to move downwards for the feed motion. At this time, the cutter shaft 32 moves downwards from the upper end of the inclined block 37. Since the inclined block 37 is wider at the top and narrower at the bottom, the spring 38 on the cutter shaft 32 extends and pushes the spring seat 381 to drive the cutter shaft 32 to move towards the side of the inclined block 37. The cutter shaft 32 simultaneously performs downward and forward feed actions. After completing the feed action, the cutter 31 is placed in the cutter groove 34 and abuts against the bottom of the cutter groove 34. The surface of the pressure roller 35 abuts against the surface of the cutter roller 34. At this time, the motor drives the cutter roller 34 to rotate. The rotation of the cutter roller 34 drives the cutter 31 to rotate, performing a cutting motion on the feed paper by shearing. At the same time, the rotation of the cutter roller 34 drives the pressure roller 35 to rotate, conveying the feed paper tape obtained after cutting to the rear end. When the splice paper needs to be removed, the pneumatic component 36 depressurizes to the set pressure of the retraction action, driving the cutting blade holder 33 to move upward to perform the retraction action. At this time, the cutting blade shaft 32 moves upward from the lower end of the inclined block 37. Since the inclined block is wider at the top and narrower at the bottom, the cutting blade shaft 32 is squeezed by the inclined block 37 and moves towards the side of the spring 38. The cutting blade shaft 32 simultaneously performs upward and backward retraction actions. After completing the retraction action, the splice paper slitting action stops.

[0030] exist Figure 2-4 In the illustrated embodiment, the tipping paper slitting device has two cutting blades 32. In other embodiments of this invention, the number of cutting blades 32 can be three, four, or other numbers, and the distance between each cutting blade 32 can be adjusted according to actual conditions, thereby enabling the tipping paper slitting device to be applicable to cigarette production with different tipping paper cutting sizes. For example, the tipping paper slitting device can be applied to the production of cigarettes with ternary cavity filter rods and visual display, such as... Figure 6 As shown, the three-component cavity filter rod visualized cigarette includes a cigarette 11 and a three-component cavity filter rod 12. The three-component cavity filter rod 12 includes a front filter rod 121, a rear filter rod 122, and a transparent cavity 123 located between the front filter rod 121 and the rear filter rod 122. The transparent cavity 123 is filled with natural coconut shell activated carbon particles, which can reduce harm and tar, and enhance and preserve aroma. The front filter rod 121 and the rear filter rod 122 are each wrapped with a layer of tipping paper 13, while the transparent cavity 123 is exposed, thus obtaining the three-component cavity filter rod visualized cigarette.

[0031] Refer again Figure 5In some preferred embodiments of this utility model, the tipping paper roll packaging equipment further includes a connecting device 2 disposed at the front end of the tipping paper cutting device 3. The connecting device 2 is used to automatically connect the tipping paper in the two paper trays 1. When the tipping paper in the lower paper tray 1 is about to run out, the connecting device 2 connects the tipping paper in the two paper trays 1 by pressing with double-sided adhesive, then cuts the tipping paper that is about to run out, and then rotates and swaps the positions of the two paper trays 1, and new tipping paper begins to be used, completing the automatic connection of the tipping paper.

[0032] In some preferred embodiments of this invention, the tipping paper rolling equipment further includes a tipping paper tape guiding device, which is disposed between the heater and the cutting roller. The tipping paper tape guiding device is used to set the distance between the tipping paper tapes obtained by the tipping paper slitting device, thereby meeting the requirements for cigarette production of corresponding sizes.

[0033] In some preferred embodiments of this utility model, the splicing paper roll packaging equipment further includes a splicing paper online correction and early warning device, which is disposed between the splicing paper belt guide device and the paper cutting wheel, and is used to provide real-time early warning of the splicing paper belt deviation distance.

[0034] The beneficial technical effects of this utility model are as follows: the cutting blade of the tipping paper slitting device cooperates with the cutting groove of the cutting roller to achieve the slitting of the tipping paper; the cutting roller cooperates with the pressure roller to achieve the conveying function of the tipping paper. When the tipping paper slitting device is applied to the tipping paper rolling equipment, the tipping paper slitting device can simultaneously undertake the functions of tipping paper slitting and tipping paper conveying, thereby reducing the number of parts in the tipping paper rolling equipment. During the production process, the travel path of the tipping paper can be shortened, reducing the phenomenon of tipping paper shaking and deviation caused by excessively long paths, thereby reducing the phenomenon of tipping paper tape flipping and cigarette air leakage, improving product yield, and improving production efficiency.
