DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1: A tipping paper air permeability testing device, such as Figure 1 and Figure 2 As shown, it includes a detection frame 1, an air delivery box 101, an air delivery plate 102, an air connection box 103, a micro-test plate 104, a material distribution plate 105 and a material distribution rotating rod 202. The air delivery box 101 and the air connection box 103 are installed on the detection frame 1. The air delivery box 101 is provided with a circular through hole at one end close to the air connection box 103, and the air connection box 103 is provided with a cylindrical groove at one end close to the air delivery box 101, and the ends of the air delivery box 101 and the air connection box 103 opposite to each other are both open. The air delivery plate 102 is slidably connected to the side of the air delivery box 101 away from the air connection box 103. The air delivery plate 102 is used to push the gas in the air delivery box 101 into the air connection box 103. The micro-test plate 104 is slidably connected in the cylindrical groove of the air connection box 103. The air permeability of the tipping paper is judged by the moving distance of the micro-test plate 104, and the air permeability of the tipping paper is qualified. Figure 2It can be seen that the upper and lower sides of the air box 103 are provided with channels for connecting the cylindrical groove with the outside, so that the micro-test plate 104 can slide freely. The detection frame 1 is rotatably connected to the material dividing rod 202, and the material dividing plate 105 is fixedly connected to the material dividing rod 202. The material dividing plate 105 is used to guide the detected packaging paper. When the micro-test plate 104 moves, it will trigger the material dividing rod 202 to drive the material dividing plate 105 to rotate, so that qualified and unqualified packaging paper fall to different sides of the material dividing plate 105.

[0027] When the tipping paper needs to be tested, the tipping paper is placed between the air delivery box 101 and the air receiving box 103, and then the air delivery box 101 is controlled to move toward the air receiving box 103. Figure 2 It can be seen that the opposite ends of the gas delivery box 101 and the gas receiving box 103 are both provided with an annular protrusion structure. The gas delivery box 101 and the gas receiving box 103 clamp the tipping paper through the protrusion structure, and then control the gas delivery plate 102 to move to the inside of the gas delivery box 101, so that the gas in the gas delivery box 101 can pass through the tipping paper and move toward the micro-test plate 104, and the gas will move between the tipping paper and the micro-test plate 104. When the gas pressure between the tipping paper and the micro-test plate 104 reaches When the gas permeability of the tipping paper meets the standard, the gas will push the micro-test plate 104 to move away from the gas delivery box 101. In a fixed time, the distance moved by the micro-test plate 104 is monitored to determine whether the air permeability of the tipping paper meets the standard. When the air permeability exceeds the standard, the distance moved by the micro-test plate 104 will be too large. When the air permeability is qualified, the distance moved by the micro-test plate 104 will not exceed the specified value. When the micro-test plate 104 moves, the material dividing plate 105 will also rotate. When the micro-test plate 104 moves too large, the material dividing plate 105 will rotate. Figure 2 From the perspective of , the upper side of the dividing plate 105 will tilt to the left. After detecting a fixed time, the air delivery box 101 will be controlled to move away from the air receiving box 103, thereby loosening the clamping of the butt paper, and the butt paper will fall downward. The dividing plate 105 guides the fallen butt paper, so that the butt paper with excessive air permeability will fall to the right side of the dividing plate 105, and the butt paper with normal air permeability will fall to the left side of the dividing plate 105.

[0028] like Figure 2-Figure 4As shown, it also includes a distribution mechanism for making the micro-test plate 104 and the dividing plate 105 cooperate with each other, the distribution mechanism is connected to the air receiving box 103, the distribution mechanism includes a fixed plate 3, an air receiving plate 301, a first spring 302, an air supply pipe 4, a deflation ring 401, an air blocking plate 402, an air blocking convex plate 403, a connecting rod 404, an air blocking guide 405, a second spring 406 and a transmission assembly, and a fixed plate 3 is fixedly connected to the side of the air receiving box 103 away from the air delivery box 101, and an air receiving plate 301 is slidably connected to the air receiving box 103, and the air receiving plate 301 It is slidably connected to the fixed plate 3 through a guide rod, and a No. 1 spring 302 is sleeved on the guide rod. When the air receiving plate 301 slides in the direction of the fixed plate 3, the No. 1 spring 302 will be compressed, and a transmission component is connected to the guide rod. When the air receiving plate 301 slides, the dividing plate 105 will be driven to rotate through the transmission component. An air supply pipe 4 is fixedly connected to the air receiving box 103, and the air supply pipe 4 is connected to the inside of the air receiving box 103. The air supply pipe 4 is used to transport gas into the air receiving box 103, so as to push the air receiving plate 301 to slide in the direction of the fixed plate 3 through the gas. The air supply pipe 4 is in the A deflation ring 401 is fixedly connected to one end of the air receiving box 103, and three fan-shaped through holes are opened on the deflation ring 401. A blocking plate 402 and a blocking convex plate 403 are coaxially rotatably connected to the deflation ring 401. The blocking plate 402 is composed of three fan-shaped plates. The blocking plate 402 is used to block the fan-shaped through holes on the deflation ring 401. The eccentric position of the blocking convex plate 403 is rotatably connected to a connecting rod 404. An end of the micro-test plate 104 away from the air delivery box 101 is fixedly connected to a blocking guide frame 405. The blocking guide frame 405 is provided with a straight-line slideway. The connecting rod 404 is connected to the air receiving box 103. 04 slides in the vertical direction in the I-shaped slideway connected to the air blocking guide 405. When the micro-test plate 104 moves away from the gas transmission box 101, it will drive the air blocking convex plate 403 to rotate through the connecting rod 404 and the air blocking guide 405, so that the air blocking plate 402 no longer blocks the through hole on the venting ring 401, so that the gas can enter the gas transmission box 101 to push the air receiving plate 301 to slide. A No. 2 spring 406 is provided on the air blocking guide 405. When the micro-test plate 104 moves away from the gas transmission box 101, the No. 2 spring 406 will be compressed.

[0029] When the micro-test plate 104 moves in the direction away from the gas delivery box 101, the No. 1 spring 302 will be compressed, and the gas blocking guide frame 405 will be driven to move synchronously. The gas blocking guide frame 405 will drive the gas blocking plate 402 to rotate through the connecting rod 404 and the gas blocking convex plate 403. When the gas blocking plate 402 rotates, the fan-shaped through hole on the air release ring 401 will gradually open. When the fan-shaped through hole on the air release ring 401 is opened, the high-pressure gas in the air supply pipe 4 will enter the air receiving box 103, and the gas will push the air receiving plate 301 to move in the direction of the fixed plate 3, and the No. 1 spring 302 will be compressed, and the micro-test plate 104 will move. The larger the distance, the larger the angle of rotation of the air blocking plate 402, and the larger the fan-shaped through hole on the air release ring 401 will be opened, so that more gas will enter the air receiving box 103 within a fixed time, and the larger the distance the air receiving plate 301 moves. When the air receiving plate 301 moves, it will drive the material dividing plate 105 to rotate through the transmission assembly to guide the butt paper through the material dividing plate 105; when the air delivery box 101 and the air receiving box 103 release the clamping of the butt paper, the compressed spring 302 will push the micro-test plate 104 to reset, and drive the air blocking guide frame 405 and the air blocking plate 402 to reset. In actual detection, since the gas flow passing through the tipping paper is relatively small, the distance moved by the micro-test plate 104 is short. By setting the distribution mechanism, the moving distance of the micro-test plate 104 can be amplified, which is not only convenient for the technicians to directly observe the test results with the naked eye, but also enables the material dividing plate 105 to automatically adjust the tilt angle according to the movement of the micro-test plate 104.

[0030] like Figure 2 As shown, the transmission assembly includes a driven plate 2 and a material dividing rod 201.

The other end of the material dividing rod 201 is rotatably connected to the material dividing plate 105, and the material dividing rod 201 is located on the lower side of the material dividing rotating rod 202.

[0031] When the air receiving plate 301 moves, it will drive the driven plate 2 to move synchronously, and the driven plate 2 drives the material distribution plate 105 and the material distribution rotating rod 202 to rotate through the material distribution pull rod 201.

An air pumping ring 410 is fixedly connected to the air pumping rod 409, and the No. 3 spring 411 is located between the air pumping ring 410 and the push plate 412.

[0033] When the air delivery box 101 moves toward the air receiving box 103, the pumping rod 409 will be pushed through the push plate 412, the No. 3 spring 411 and the pumping ring 410, so that the pumping rod 409 drives the pumping plate 408 to move toward the direction of the air supply pipe 4, thereby pushing the gas in the pumping pipe 407 into the air supply pipe 4 and compressing the gas. When the gas is compressed to a certain extent, the push plate 412 will gradually compress the No. 3 spring 411, and the No. 3 spring 411 can play a buffering and protective role to prevent the hard compressed air from causing the pumping pipe 407 and the air supply pipe 4 to rupture. When the fan-shaped through hole on the deflation ring 401 is opened, the compressed air will enter the air receiving box 103 through the air supply pipe 4.

The drive plate 601 is fixed to the outer end of the gas delivery plate 102, and the drive plate 601 is used to push the gas delivery plate 102 to move so as to push the gas into the gas receiving box 103.

[0035] The gas delivery guide frame 6 guides the gas delivery box 101 and the driving plate 601, so that the gas delivery box 101 and the gas delivery plate 102 can move smoothly.

The friction wheel 703 is exposed upward from the through hole in the middle of the material tray 7. The rotating shaft of the friction wheel 703 is rotatably connected to a feeding gear 704 through a one-way bearing, so that the feeding gear 704 can only drive the friction wheel 703 to rotate in one direction. A feeding rack 706 is fixed to the air transmission box 101, and the feeding rack 706 is meshed with the feeding gear 704. The feeding rack 706 can drive the friction wheel 703 to rotate through the feeding gear 704 only when it is away from the material tray 7. Two electric rollers 707 are symmetrically connected to the lower side of the material tray 7. The electric rollers 707 are rollers that can rotate automatically in the prior art. The electric rollers 707 are located on both sides of the material channel 701, and the adjacent sides of the two electric rollers 707 are close together.

[0039] The staff will cut the connecting device to be tested into a square in advance, and then stack the cut tipping paper on the material tray 7. The tipping paper at the bottom will contact the friction wheel 703. When the air delivery box 101 moves away from the air receiving box 103, the friction wheel 703 will be driven to rotate through the feeding gear 704 and the feeding rack 706. The friction wheel 703 will use the friction force to make the bottom tipping paper move downward along the material channel 701, and the tipping paper will pass between the two electric rollers 707. The two electric rollers 707 rotate relatively, and the tipping paper can be further transported downward by the two electric rollers 707. Since the two electric rollers 707 are in close contact, the tipping paper will not fall downward under the action of gravity, so that the air delivery box 101 and the air receiving box 103 can clamp the tipping paper; when the air delivery box 101 approaches the air receiving box 103, the friction wheel 703 will not be driven to rotate by the feeding gear 704.

A lifting assembly is connected to the air delivery box 101, and the lifting assembly is used to drive the clamping rod 801 to move up and down.

[0041] The lower side of the tipping paper will be conveyed between the two clamping plates 804. In the process of the air delivery box 101 approaching the air receiving box 103, the lifting assembly will drive the clamping rod 801 to slide downward along the clamping frame 8, and the clamping rod 801 will drive the clamping plate 804 to disengage from the contact rod 805. Then the clamping plate 804 will move relative to each other under the push of the No. 5 spring 803, thereby clamping the tipping paper through the clamping plate 804, and in the process of the clamping rod 801 continuing to move downward, the clamping plate 804 will tighten the tipping paper for testing; in the process of the air delivery box 101 moving away from the air receiving box 103, the lifting assembly will drive the clamping rod 801 to move upward along the clamping frame 8. In this process, the contact rod 805 will squeeze the clamping plate 804 to both sides, so that the clamping plate 804 releases the clamping of the tipping paper, and the No. 5 spring 803 will be compressed.

When the gas transmission box 101 moves away from the gas receiving box 103, the lifting rack 902 will drive the lifting gear 901 to rotate counterclockwise, and the lifting gear 901 will drive the clamping rod 801 to move upward through the lifting rod 903 and the lifting shaft 904.

[0045] When it is necessary to place the tipping paper on the material tray 7, the staff will first push the pressure plate 12 upwards, and then place the tipping paper under the pressure plate 12. The No. 6 spring 13 will apply a downward force to the pressure plate 12 to increase the friction between the tipping paper and the friction wheel 703.
