[0002] In the cigarette manufacturing process, tipping paper is needed to make filter tips of cigarettes. With the wide application of cigarette reducing process, it is necessary to use punching equipment to make laser punching on tipping paper. The punching equipment mainly includes a paper feeding roller, a paper collecting roller, a transition roller, a laser puncher and a zero meter mechanism. The paper feeding roller is used to feed the tipping paper without punching, the paper collecting roller is used to wind the punched tipping paper, and the transition roller is installed between the paper feeding roller and the paper collecting roller, which is used to limit the conveying path of the tipping paper. The laser puncher is used to make laser punching on the tipping paper. The zero meter mechanism is installed at the corresponding position of the paper collecting roller, which is used to wind the waste tipping paper which has not completed punching or has unqualified punching.

[0003] Specifically, during the starting stage of the punching equipment, part of the tipping paper without laser punching and the tipping paper with unqualified punching interval due to the low conveying speed of the tipping paper at the initial stage of the equipment operation need to be wound by the zero meter mechanism.

DETAILED DESCRIPTION

[0027] The advantages and features of the utility model and the method for realizing them will become apparent from the following embodiments described in detail in conjunction with the drawings. However, the utility model is not limited to the following disclosed embodiments, but can be realized in various different forms, and the present embodiments are provided only to accomplish the disclosure of the utility model and make those skilled in the art fully understand the scope of the utility model, and the utility model is only limited by the scope of claims. The same reference signs represent the same constituent elements throughout the specification.

[0028] Hereinafter, the present application will be described in detail with reference to the accompanying drawings.

[0029] As shown in Figure 1 and Figure 2 , a zero-meter mechanism 300 of a cigarette paper punching device is provided for removing unqualified cigarette paper in the cigarette paper punching device. The zero-meter mechanism 300 of the cigarette paper punching device comprises a paper winding assembly 310 and a brake assembly. Among them, the paper winding assembly 310 comprises a base 311 and a waste paper roller 312, a cutting piece 313 and a second driving piece 314 arranged on the base 311. The base 311 plays a whole supporting role and provides space for the installation of various parts. The waste paper roller 312 is installed on the base 311, and the waste paper roller 312 is used to wind the unqualified cigarette paper. The second driving piece 314 comprises a cylinder and a motor, the output end of the cylinder is connected with the waste paper roller 312 to drive the linear motion of the waste paper roller 312. The output end of the motor is connected with the waste paper roller 312 to drive the rotation of the waste paper roller 312 around its own axis. The cutting piece 313 is installed on the base 311, which is used to cut off the unqualified cigarette paper. When it is needed to wind the unqualified cigarette paper, the cylinder drives the waste paper roller 312 to contact with the cigarette paper to wind the unqualified cigarette paper on the waste paper roller 312; when the cigarette paper is punched qualified, the cutting piece 313 cuts off the cigarette paper, and the cylinder drives the waste paper roller 312 away from the qualified cigarette paper.

[0030] The brake assembly plays a role of stopping the waste paper roller 312. When the waste paper roller 312 is away from the qualified cigarette paper, the waste paper roller 312 will continue to rotate at high speed under the action of inertia. Therefore, the brake assembly is used to limit the rotation of the waste paper roller 312 to facilitate the operator to quickly remove the unqualified cigarette paper on the waste paper roller 312. The brake assembly comprises a first driving piece 3 and a pressing part 2. In this embodiment, the first driving piece 3 is a cylinder. In other embodiments, the first driving piece 3 can also be a hydraulic cylinder or an electric telescopic piece. The first driving piece 3 is installed on the base 311, and the pressing part 2 is installed on the output end of the first driving piece 3. The first driving piece 3 is used to drive the pressing part 2 to approach or move away from the waste paper roller 312, so that the pressing part 2 can limit the rotation of the waste paper roller 312. When the waste paper roller 312 needs to be stopped, the pressing part 2 approaches the waste paper roller 312 and abuts, and the friction between the two makes the waste paper roller 312 slow down and stop rotating.

[0031] In this embodiment, the cigarette paper is water-based paper used for making filter tips of cigarette.

[0032] Specifically, as shown in Figure 2 , the brake assembly further comprises a mounting seat 1, the mounting seat 1 is arranged on the base 311, and the pressing part 2 is slidingly arranged on the mounting seat 1. The sliding connection between the pressing part 2 and the mounting seat 1 is used to control the movement direction of the pressing part 2.

[0033] The mounting base 1 comprises a bracket 11, a sliding rail 13 and an ear plate 12. The bracket 11 is in a "U" shape structure, and has an open end which is mounted on the base 311 by screws, bolts or other fasteners. The ear plate 12 is arranged at the end of the bracket 11 away from the base 311, and the ear plate 12 is two, which are arranged in a horizontal direction and spaced apart, and a space capable of accommodating the sliding rail 13 and the first driving member 3 is formed between the two ear plates 12. The sliding rail 13 is arranged between the two ear plates 12. The first driving member 3 is a pneumatic cylinder, and the fixed end of the pneumatic cylinder is mounted on the ear plate 12, and the telescopic end (i.e. the output end) of the pneumatic cylinder is connected with the extrusion part 2.

[0034] The extrusion part 2 comprises a sliding block 23, a friction plate 21, a connecting plate 22 and an adapter plate 24. The sliding block 23 is in sliding connection with the sliding rail 13. The adapter plate 24 is in an "L" shape structure, and the output end of the first driving member 3 is mounted on the sliding block 23 through the adapter plate 24. Of course, in other embodiments, the output end of the first driving member 3 can be directly connected with the sliding block 23 to drive the sliding block 23 to slide relative to the sliding rail 13. The connecting plate 22 is adjustably arranged on the sliding block 23, and the friction plate 21 is used to abut against the waste paper roller 312. In actual application, the position of the connecting plate 22 can be adjusted according to actual conditions, so that the friction plate 21 can be well matched with the waste paper roller 312. Specifically, the connecting plate 22 is provided with a guide groove 221 which penetrates through the opposite two side faces of the connecting plate 22. The sliding block 23 is provided with a screw 25, and the screw 25 is arranged in the guide groove 221. When the screw 25 is loosened from the connecting plate 22, the screw 25 can move along the length direction of the guide groove 221. The length direction of the guide groove 221 is consistent with the moving direction of the friction plate 21 towards the waste paper roller 312. The friction plate 21 is arranged at the end of the connecting plate 22 away from the sliding block 23. During work, when it is needed to stop the waste paper roller 312, the output end of the pneumatic cylinder drags the sliding block 23 to slide relative to the sliding rail 13, so that the sliding block 23 drives the friction plate 21 to approach the waste paper roller 312. The friction plate 21 abuts against the waste paper roller 312 to stop the waste paper roller 312 by using the friction force between them.

[0035] Specifically, the extrusion part 2 is arranged directly above the waste paper roller 312, that is, the entire stopping assembly is located directly above the waste paper roller 312. The first driving member 3 drives the sliding block 23 and the friction plate 21 to move up and down in the vertical direction. This structure is conducive to the operator to clearly see the position of the extrusion part 2, and avoids mechanical injury when removing the cigarette paper.

[0036] In another embodiment, with reference to Figure 3As shown, the friction plate 21 is provided with an arc surface on the side facing the side surface of the waste paper roller 312. The arc surface of the friction plate 21 is used to abut against the waste paper roller 312. It can be understood that the arc surface structure of the friction plate 21 is beneficial to increase the friction surface between the friction plate 21 and the waste paper roller 312, and improve the braking effect. For the convenience of processing, the friction plate 21 is directly processed into an arc plate, and the concave side thereof is used to abut against the waste paper roller 312.

[0037] In another embodiment, referring to Figure 4 As shown, the connecting plate 22 is elastically connected with the sliding block 23. The connecting plate 22 is provided with a guide groove 221 penetrating through the opposite side surfaces of the connecting plate 22. The sliding block 23 is provided with a pin 231, the pin 231 is arranged in the guide groove 221, and the pin 231 can move along the length direction of the guide groove 221. The length direction of the guide groove 221 is consistent with the moving direction of the friction plate 21 towards the waste paper roller 312. The pin 231 is provided with a spring 232, one end of the spring 232 away from the pin 231 is fixedly connected with the groove wall of the guide groove 221, and the spring 232 is contained in the guide groove 221. This mechanism is used to realize the elastic connection between the connecting plate 22 and the sliding block 23. The spring 232 can play a buffering role. When the first driving member 3 drives the friction plate 21 to abut against the waste paper roller 312, the spring 232 can gradually increase the friction between the two under the buffering action, thereby avoiding the cigarette paper wound on the waste paper roller 312 from being broken due to the sudden excessive force on the waste paper roller 312, and avoiding the waste paper roller 312 from being subjected to excessive impact when braking.

[0038] As Figure 1 and Figure 2As shown, the zero-meter mechanism 300 of the cigarette paper punching equipment is applied to the cigarette paper punching equipment, and the cigarette paper punching equipment further comprises a paper releasing roller 100, a paper collecting roller 200, a transition roller 400, a tension roller 500, a deviation rectifying device 600, a laser puncher 700, an online monitoring device 800 and a paper pressing roller 900. Among them, the paper releasing roller 100 is used to wind the un-punched cigarette paper (i.e. raw material), and the paper collecting roller 200 is used to wind the finished cigarette paper after punching. The transition roller 400 is multiple, and multiple transition rollers 400 are arranged between the paper releasing roller 100 and the paper collecting roller 200. The cigarette paper released from the paper releasing roller 100 passes through the multiple transition rollers 400 in turn and is wound on the paper collecting roller 200, and the transition roller 400 is used to limit the conveying path of the cigarette paper. Along the conveying direction of the cigarette paper, the tension roller 500, the deviation rectifying device 600, the laser puncher 700 and the online monitoring device 800 are arranged in turn from the direction of the paper releasing roller 100 to the paper collecting roller 200. Among them, the cigarette paper is wound on the tension roller 500, and the movement of the tension roller 500 is used to straighten the cigarette paper, so as to facilitate the subsequent punching operation. The deviation rectifying device 600 is used to correct the position of the cigarette paper, so as to facilitate the positioning of the punching position. The laser puncher 700 is used to punch the cigarette paper. The online monitoring device 800 is used to detect the punching quality, including the hole diameter and the distribution density of the holes. The zero-meter mechanism 300 of the cigarette paper punching equipment is used to remove the unqualified cigarette paper after punching. When the online monitoring device 800 detects that the punching is unqualified, the waste paper roller 312 is close to the paper collecting roller 200, and the unqualified cigarette paper is wound on the waste paper roller 312. When the online monitoring device 800 detects that the punching is qualified, the cutting piece 313 is used to cut off the cigarette paper, and the waste paper roller 312 is away from the paper collecting roller 200. The paper pressing roller 900 is arranged at a position adjacent to the paper collecting roller 200. After the punching is qualified, the paper pressing roller 900 abuts against the paper collecting roller 200, and under the action of the paper pressing roller 900, the cigarette paper is wound on the paper collecting roller 200.

[0039] The beneficial effects of the embodiment are that: by arranging the brake assembly in the zero-meter mechanism 300 of the cigarette paper punching equipment, when the waste paper roller 312 receives the unqualified cigarette paper and is away from the paper collecting roller 200, the first driving piece 3 is used to drive the extrusion part 2 to extrude between the extrusion part 2 and the waste paper roller 312, so as to promote the waste paper roller 312 to slow down and stop rotating, and then the operator can quickly remove the unqualified cigarette paper on the waste paper roller 312, so as to avoid that the unqualified cigarette paper scratches the operator due to the continuous rotation of the waste paper roller 312. Therefore, the zero-meter mechanism 300 of the cigarette paper punching equipment has the characteristics of high work efficiency and high safety.

[0040] Although the embodiments of the present application have been described above with reference to the drawings, the present application is not limited to the above embodiments, but can be manufactured in various forms, and it will be understood by those skilled in the art that the present application can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present application. Therefore, it should be understood that the above-described embodiments are exemplary in all aspects and are not limiting.
