Description

Technical Field

[0001] The invention relates to the technical field of waterproof paper detection, and in particular to a waterproof paper anti-penetration detection device. Background Art

[0002] Waterproof paper is a paper material with waterproof properties. Its characteristics include moisture resistance, water resistance, oil resistance, etc. It is widely used in packaging, printing, labeling and other fields. Waterproof paper can be divided into many types, including but not limited to the following types: coated paper, synthetic paper, graphene paper and natural paraffin paper. In the production process of waterproof paper, it is necessary to conduct anti-penetration testing on the waterproof paper to determine whether the waterproof paper is qualified. Chinese utility model patent CN219179164U discloses a waterproof paper anti-penetration performance testing device, but the device also has the following defects:

[0003] First, the conventional waterproof paper penetration test mostly uses dripping or spraying to sprinkle the test liquid on the waterproof paper, which has little impact on the waterproof paper. However, in the above patent, the external test liquid source needs to enter the water injection pipe through a lifting pump. When the valve is opened, the test liquid will have a greater impact force on the waterproof paper due to the hydraulic pressure, and the waterproof paper may eventually be broken due to water impact.

[0004] Second, if the current waterproof paper has strong anti-penetration performance, the sprayed test liquid will remain on the waterproof paper. When the waterproof paper is replaced later, the test liquid on the waterproof paper may be spilled onto the humidity sensor in the test box, which will affect the next round of testing;

[0005] Third, if the current waterproof paper has poor anti-penetration performance, the sprayed test liquid will pass through the waterproof paper and fall into the test box. Then, before the next round of testing begins, the test liquid in the test box needs to be removed. Therefore, every time the waterproof paper is tested, the test liquid in the test box needs to be removed, which will ultimately increase the test time and reduce the test efficiency.

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] refer to Figures 1 to 19 The waterproof paper anti-penetration detection device shown in the figure comprises a vertical support frame, on which a pressing mechanism, a water spraying mechanism and a water permeability detection mechanism are sequentially distributed from top to bottom in the vertical direction. The pressing mechanism comprises a pressure rod 1 vertically connected to the support frame for sliding, and the water spraying mechanism comprises a connecting plate 2, a pressing plate 3, a water tank 4 and a pressure extraction member. The connecting plate 2 is horizontally fixed to the lower end of the pressure rod 1, and the pressing plate 3 is horizontally arranged below the connecting plate 2. A through hole 5 is arranged on the pressing plate 3, and the pressing plate 3 is elastically connected to the connecting plate 2. A plurality of groups of presser feet 6 are arranged at the bottom of the pressing plate 3. The water tank 4 is fixedly arranged on the side of the support frame, and the top of the water tank 4 is an open structure. The pressure extraction member is arranged between the connecting plate 2 and the pressing plate 3, and the pressure extraction member comprises a water spraying tube 7 and a piston 8, as shown in FIG. Fig.12 As shown, the water spray barrel 7 is vertically connected to the pressure plate 3, the piston 8 is vertically connected to the connecting plate 2, and the cap end of the piston 8 extends downward into the water spray barrel 7. The lower end of the water spray barrel 7 is provided with a water spray port 9 facing the through port 5, and a No. 1 one-way valve is provided in the water spray port 9. Fig. 9As shown, a water inlet 10 is provided on the outer wall of the lower end of the water spray tube 7, and a No. 2 one-way valve is connected to the water inlet 10, and a hose 11 leading to the water tank 4 is connected to the No. 2 one-way valve. The water permeability detection mechanism includes a No. 1 platform 12, a No. 2 platform 13 and a water recovery component. The No. 1 platform 12 is fixedly arranged below the pressure plate 3, and the No. 2 platform 13 is fixedly arranged below the No. 1 platform 12. A through groove 14 facing the water spray tube 7 is opened on the No. 1 platform 12. The water recovery component includes a scraper bar 15 and a water collecting box 16. The scraper bar 15 is horizontally arranged on the top of the No. 1 platform 12, and the water collecting box 16 is arranged in the through groove 14. The top of the water collecting box 16 is an open structure, and the water collecting box 16 is located below the scraper bar 15.

[0042] There is dyed water in the water tank 4. Before the waterproof paper is subjected to penetration testing, the dyed water in the water tank 4 needs to be injected into the water spray barrel 7. At this time, the pressure rod 1 is pressed down, and the pressure rod 1 drives the pressure plate 3 to descend through the connecting plate 2. When the pressure foot 6 arranged at the bottom of the pressure plate 3 is pressed on the No. 1 platform 12, the distance between the pressure plate 3 and the connecting plate 2 is shortened, and the cap end of the piston 8 gradually extends into the water spray barrel 7. Thereafter, the pressure rod 1 is lifted, and the connecting plate 2 immediately rises following the pressure rod 1. Due to the elastic connection between the pressure plate 3 and the connecting plate 2, the pressure plate 3 will be pressed on the No. 1 platform 12 during the rising process of the connecting plate 2. Then, at this time, only the piston 8 extending into the water spray barrel 7 will rise, while the water spray barrel 7 connected to the pressure plate 3 will not move. Finally, the dyed water in the water tank 4 is drawn into the water spray barrel 7 through the water inlet 10 through the negative pressure suction force generated when the piston 8 rises.

[0043] After the dyed water is injected into the water spray barrel 7, the waterproof paper is spread flat on the No. 1 platform 12, and the test paper is spread flat on the No. 2 platform 13. Then, the pressure rod 1 is pressed down again. As the pressure rod 1 is pressed down, the connecting plate 2 will drive the pressing plate 3 to press the waterproof paper on the No. 1 platform 12. When the pressure foot 6 provided at the bottom of the pressing plate 3 is pressed on the waterproof paper, the connecting plate 2 continues to descend. At this time, the piston 8 connected to the connecting plate 2 will continue to be pushed into the water spray barrel 7, so that the dyed water in the water spray barrel 7 will be sprayed from the water spray port 9 onto the waterproof paper. When the dyed water falls on the waterproof paper, the color of the test paper is continuously observed. If the test paper changes color, it means that the current waterproof paper has poor anti-permeability. If the test paper does not change color, it means that the current waterproof paper has good anti-permeability.

[0044] After the detection is completed, the pressure rod 1 is lifted up and reset. At this time, the dyed water in the water tank 4 is pumped into the water spray barrel 7 again through the negative pressure suction force generated by the rising of the piston 8. When the pressure rod 1 is lifted up and reset, the waterproof paper is replaced. In this process, one end of the waterproof paper is held and the waterproof paper is pulled out. If the current waterproof paper has good permeability resistance, the dyed water will remain on the top surface of the waterproof paper. When the waterproof paper is pulled out, the dyed water remaining on the top surface of the waterproof paper will be scraped toward one end of the waterproof paper by the scraper strip 15. Finally, when the waterproof paper is completely pulled out from the No. 1 platform 12, the dyed water on the waterproof paper will be scraped into the water collecting box 16. Since the current detection paper does not contact the dyed water, the detection paper does not need to be replaced. If the current waterproof paper has poor permeability resistance, the dyed water will drip through the waterproof paper onto the detection paper. Therefore, when replacing the waterproof paper, the detection paper needs to be replaced together. Among them, the dyed water retained on the waterproof paper is recovered by the water collecting box 16, and finally part of the dyed water is recycled.

[0045] In order to show the specific structure of the pressing mechanism, the following features are set:

[0046] The support frame includes a bottom plate 17, a No. 1 flat plate 18, a No. 2 flat plate 19 and two vertical plates 20. The two vertical plates 20 are spaced apart in the horizontal direction, and each vertical plate 20 is fixed on the bottom plate 17. The No. 1 flat plate 18 and the No. 2 flat plate 19 are fixed between the two vertical plates 20, and the No. 1 flat plate 18 is located directly above the No. 2 flat plate 19. The pressing mechanism also includes a No. 1 rotating frame 21, a No. 2 rotating frame 22, an arc rod 23, a connecting block 24 and two straight rods 25. The lower end of the No. 1 rotating frame 21 is hinged to the No. 1 flat plate 18, and the lower end of the No. 2 rotating frame 22 is hinged to the No. 2 flat plate 19. The two straight rods 25 are respectively arranged on the sides of the No. 1 rotating frame 21, and the two ends of each straight rod 25 are respectively hinged to the middle part of the No. 1 rotating frame 21 and the upper end of the No. 2 rotating frame 22. The pressing rod 1 passes through the No. 1 flat plate 18 and the No. 2 flat plate 19 downward in sequence, and the connecting block 24 is located below the No. 1 flat plate 18. Figure 5 As shown, the connecting block 24 is fixedly connected to the pressure rod 1, and a horizontal rotating rod 26 is provided on the second rotating frame 22. One end of the arc rod 23 is hinged to the connecting block 24, and the other end of the arc rod 23 is fixedly connected to the rotating rod 26.

[0047] When the pressure rod 1 needs to be lowered, the No. 1 turntable 21 is rotated downward. At this time, the No. 1 turntable 21 drives the No. 2 turntable 22 to rotate downward through the two straight rods 25. When the No. 2 turntable 22 rotates downward, the No. 2 turntable 22 drives the connecting block 24 to move downward through the arc rod 23, and finally drives the pressure rod 1 to descend through the connecting block 24. When the pressure rod 1 needs to be raised, the No. 1 turntable 21 is rotated upward, then the No. 2 turntable 22 will be driven to rotate upward, and finally, through the transmission of the arc rod 23, the connecting block 24 will drive the pressure rod 1 to rise. In summary, through the transmission of the No. 1 turntable 21, the No. 2 turntable 22, the arc rod 23 and the straight rod 25, the operator can save more effort when pressing the pressure rod 1, so as to facilitate the operator to work for a long time.

[0048] In order to enable the pressure rod 1 to hover in the raised state, the following features are set:

[0049] A horizontal insertion rod 27 is fixed on the No. 1 rotating frame 21, a vertical support rod 28 is fixed on the top of the No. 1 flat plate 18, an elastic ring 29 is fixed on the top of the support rod 28, and a No. 1 notch 30 is provided on the elastic ring 29 for the insertion of the insertion rod 27, and a vertical shifting rod 31 is fixed on the upper end of the No. 1 rotating frame 21.

[0050] The lever 31 provided on the No. 1 turret 21 is convenient for the operator to drive the No. 1 turret 21. When the No. 1 turret 21 is shifted to be vertical, the insertion rod 27 provided on the No. 1 turret 21 is inserted into the elastic ring 29 through the No. 1 notch 30, so that the insertion rod 27 is fixed by the elastic ring 29, and finally it is ensured that the pressure rod 1 can be suspended in the ascending state.

[0051] In order to specifically demonstrate how the pressure plate 3 is elastically connected to the connecting plate 2, the following features are set:

[0052] Four vertical shafts 32 distributed in a matrix are formed on the top of the pressure plate 3. Each vertical shaft 32 passes through the connecting plate 2 upward. One end of each vertical shaft 32 passing through the connecting plate 2 is threaded, and a No. 1 limit nut 33 is screwed on the threaded end of each vertical shaft 32. A No. 1 spring 34 is sleeved on each vertical shaft 32, and the two ends of the No. 1 spring 34 respectively conflict with the bottom of the connecting plate 2 and the top of the pressure plate 3.

[0053] The four No. 1 springs 34 are used to keep the pressure plate 3 away from the connecting plate 2, and the No. 1 limit nut 33 is used to prevent the vertical shaft 32 from separating from the connecting plate 2. When the pressure rod 1 drives the connecting plate 2 to descend, the pressure plate 3 suspended below the connecting plate 2 will move along with the connecting plate 2. When the pressure plate 3 is pressed on the No. 1 platform 12, the pressure plate 3 stops descending, and the connecting plate 2 will continue to descend. At this time, each No. 1 spring 34 will be compressed by the connecting plate 2 to generate elastic force, and when the pressure plate 3 stops moving, the descending connecting plate 2 will drive the piston 8 to descend in the water spray barrel 7. Finally, the dyed water in the water spray barrel 7 is pressed out by the downward pressure of the piston 8. When the pressure rod 1 drives the connecting plate 2 to rise, the No. 1 spring 34 will continue to press the pressure plate 3 on the No. 1 platform 12 through the elastic force. At this time, the pressure plate 3 does not move, and the connecting plate 2 continues to rise. In this process, the rising connecting plate 2 will drive the piston 8 to rise in the water spray barrel 7. Finally, the dyed water in the water tank 4 is drawn into the water spray barrel 7 through the negative pressure suction force generated by the piston 8 when it rises. When the connecting plate 2 rises to conflict with the No. 1 limit nut 33, the pressure plate 3 will be driven to rise together with the connecting plate 2.

[0054] In order to show the specific installation method of the water spray barrel 7, the following features are set:

[0055] A vertical support 35 is fixedly provided on the top of the pressure plate 3, a water spraying tube 7 is vertically fixedly connected to the vertical support 35, the lower end of the water spraying tube 7 is gradually tapered, a water spraying port 9 is provided on the tapered end of the water spraying tube 7, and a rubber plug 36 is fixedly provided on the lower end of the piston 8. Fig.12 As shown, the rubber plug 36 slides in the water spray barrel 7 , and the rubber plug 36 is the cap end of the piston 8 , and the upper end of the piston 8 is fixedly connected to the bottom of the connecting plate 2 .

[0056] When the piston 8 descends, the rubber plug 36 arranged at the lower end of the piston 8 will slide downward in the water spray barrel 7, and the dyed water in the water spray barrel 7 will be pressed out from the water outlet 9 by the rubber plug 36. When the piston 8 rises, the rubber plug 36 will slide upward in the water spray barrel 7, and negative pressure will be generated in the water spray barrel 7 by the upward sliding rubber plug 36, so that the dyed water in the water tank 4 will be drawn into the water spray barrel 7.

[0057] In order to show the specific structure of the No. 1 check valve, the following features are set:

[0058] The first check valve comprises a first valve plate 37, a second spring 38 and a first circular sealing plug 39. A first retaining ring 40 is coaxially formed in the water spray port 9. Fig. 9As shown, a conical surface 41 which tapers upward is formed on the inner ring of the No. 1 baffle ring 40, a circular plug 39 is arranged in the water outlet 9 and below the No. 1 baffle ring 40, a valve plate 37 is arranged in the water outlet 9 and above the No. 1 baffle ring 40, a connecting rod 42 which connects the No. 1 valve plate 37 and the circular plug 39 is arranged between the two, a No. 2 spring 38 is arranged in the water outlet 9, and the No. 2 spring 38 is sleeved on the connecting rod 42, and the two ends of the No. 2 spring 38 are respectively in conflict with the No. 1 valve plate 37 and the No. 1 baffle ring 40, the No. 1 valve plate 37 is circular, the outer diameter of the No. 1 valve plate 37 is consistent with the inner diameter of the water outlet 9, and a plurality of No. 2 notches 43 are provided at the outer edge of the No. 1 valve plate 37.

[0059] In the initial state, the No. 2 spring 38 generates elastic force to drive the No. 1 valve plate 37 to rise, so that the No. 1 valve plate 37 will drive the No. 1 circular seal 39 upward to block the No. 1 baffle ring 40 through the No. 1 connecting rod 42. At this time, the dyed water in the water spray barrel 7 will not flow out from the water spray port 9. When the piston 8 is pressed down, the dyed water in the water spray barrel 7 acts on the No. 1 circular seal 39. Finally, the water pressure will overcome the elastic force of the No. 2 spring 38 to drive the No. 1 circular seal 39 to descend. When the No. 1 circular seal 39 descends, the No. 1 baffle ring 40 will open, so that the dyed water in the water spray barrel 7 will pass through the No. 2 notch 43 and the No. 1 baffle ring 40 in turn and be sprayed out from the water spray port 9.

[0060] In order to show the specific structure of the No. 2 check valve, the following features are set:

[0061] The second check valve includes a valve tube 44, a second valve plate 45 and a second circular sealing plug 46. Fig.15 As shown, one end of the valve tube 44 is fixed in the water inlet 10, and a No. 2 baffle ring 47 is coaxially formed in the valve tube 44, and a No. 2 conical surface 48 which gradually shrinks toward the outside of the water inlet 10 is formed on the inner ring of the No. 2 baffle ring 47, and a No. 2 circular plug 46 and a No. 2 valve plate 45 are both arranged in the valve tube 44, and the No. 2 circular plug 46 and the No. 2 valve plate 45 are respectively located on both sides of the No. 2 baffle ring 47, and the No. 2 circular plug 46 is close to the water spray tube 7, and a No. 2 connecting rod 49 is provided between the No. 2 valve plate 45 and the No. 2 circular plug 46 to connect the two, the outer diameter of the No. 2 valve plate 45 is consistent with the inner diameter of the valve tube 44, and a number of No. 3 notches 50 are opened at the outer edge of the No. 2 valve plate 45, and one end of the hose 11 is fixedly connected to the end of the valve tube 44 away from the water inlet 10.

[0062] When the piston 8 is pressed down, the rubber plug 36 arranged at the lower end of the piston 8 will squeeze the dyed water in the water spray barrel 7, so that part of the dyed water will act on the second circular sealing plug 46, so that the second circular sealing plug 46 is pressed toward the second baffle ring 47 by the dyed water, and finally the second baffle ring 47 is blocked by the second circular sealing plug 46. Then, when the second baffle ring 47 is blocked, the dyed water cannot flow out through the water inlet 10, so the dyed water can only flow out from the water spray port 9. When the piston 8 rises, the rubber plug 36 arranged at the lower end of the piston 8 6 causes negative pressure to be generated in the water spray tube 7, so that the No. 2 circular sealing plug 46 will be driven to move toward the water spray tube 7 due to the suction force of the negative pressure, and the No. 2 circular sealing plug 46 will be separated from the No. 2 retaining ring 47, and the dyed water in the water tank 4 will flow into the valve pipe 44 through the hose 11, and finally the dyed water flowing into the valve pipe 44 will flow into the water spray tube 7 through the No. 3 notch 50 and the No. 2 retaining ring 47 in sequence. At the same time, the No. 1 retaining ring 40 is blocked by the No. 1 circular sealing plug 39, so the dyed water flowing into the water spray tube 7 at this time will not flow out from the water spray port 9.

[0063] In order to show the specific installation method of the scraper strip 15, the following features are set:

[0064] The top of the first platform 12 is formed with two blocking bars 51 spaced apart in the horizontal direction. Fig.16 As shown, each baffle 51 is formed with a vertically upward limiting shaft 52 on its side. Figure 2 As shown, the scraper strip 15 is horizontally arranged between the two baffles 51, and both ends of the scraper strip 15 are formed with horizontal support plates 53, each limiting shaft 52 passes through the support plate 53, the top of each limiting shaft 52 is threaded, and the top of each limiting shaft 52 is screwed with a No. 2 limiting nut 54, and each limiting shaft 52 is sleeved with a No. 3 spring 55, and the two ends of the No. 3 spring 55 are respectively in conflict with the No. 2 limiting nut 54 and the support plate 53, and the inner bottom of the water collecting box 16 is formed with a slope 56, as shown in FIG. Fig.18 As shown, a water outlet 57 is formed at one end of the water collecting box 16 .

[0065] Each of the three springs 55 presses the support plate 53 downward by elastic force, so that the scraper strip 15 is pressed toward the first platform 12. Figure 2As shown, when laying the waterproof paper, the scraper bar 15 is lifted up, and then the waterproof paper is passed between the scraper bar 15 and the No. 1 platform 12. When the waterproof paper is laid flat on the No. 1 platform 12, the scraper bar 15 is released to press the scraper bar 15 against the waterproof paper. When the waterproof paper is laid on the No. 1 platform 12, the waterproof paper is located between the two baffle bars 51, and the baffle bars 51 are used to locate the laying position of the waterproof paper. The length of the water collecting box 16 is not less than the width of the waterproof paper. When the dyed water stored on the waterproof paper is scraped into the water collecting box 16 by the scraper bar 15, the water in the water collecting box 16 will flow to the water outlet 57 through the slope 56, and finally be discharged through the water outlet 57. In actual use, a guide pipe can be connected to the water outlet 57, and the water in the water collecting box 16 can be discharged through the guide pipe, so as to realize the recycling of the dyed water.

[0066] Working principle:

[0067] There is dyed water in the water tank 4. Before the waterproof paper is subjected to penetration testing, the dyed water in the water tank 4 needs to be injected into the water spray barrel 7. At this time, the pressure rod 1 is pressed down, and the pressure rod 1 drives the pressure plate 3 to descend through the connecting plate 2. When the pressure foot 6 arranged at the bottom of the pressure plate 3 is pressed on the No. 1 platform 12, the distance between the pressure plate 3 and the connecting plate 2 is shortened, and the cap end of the piston 8 gradually extends into the water spray barrel 7. Thereafter, the pressure rod 1 is lifted, and the connecting plate 2 immediately rises following the pressure rod 1. Due to the elastic connection between the pressure plate 3 and the connecting plate 2, the pressure plate 3 will be pressed on the No. 1 platform 12 during the rising process of the connecting plate 2. Then, at this time, only the piston 8 extending into the water spray barrel 7 will rise, while the water spray barrel 7 connected to the pressure plate 3 will not move. Finally, the dyed water in the water tank 4 is drawn into the water spray barrel 7 through the water inlet 10 through the negative pressure suction force generated when the piston 8 rises.

[0068] After the dyed water is injected into the water spray barrel 7, the waterproof paper is spread flat on the No. 1 platform 12, and the test paper is spread flat on the No. 2 platform 13. Then, the pressure rod 1 is pressed down again. As the pressure rod 1 is pressed down, the connecting plate 2 will drive the pressing plate 3 to press the waterproof paper on the No. 1 platform 12. When the pressure foot 6 provided at the bottom of the pressing plate 3 is pressed on the waterproof paper, the connecting plate 2 continues to descend. At this time, the piston 8 connected to the connecting plate 2 will continue to be pushed into the water spray barrel 7, so that the dyed water in the water spray barrel 7 will be sprayed from the water spray port 9 onto the waterproof paper. When the dyed water falls on the waterproof paper, the color of the test paper is continuously observed. If the test paper changes color, it means that the current waterproof paper has poor anti-permeability. If the test paper does not change color, it means that the current waterproof paper has good anti-permeability.

[0069] After the detection is completed, the pressure rod 1 is lifted up and reset. At this time, the dyed water in the water tank 4 is pumped into the water spray barrel 7 again through the negative pressure suction force generated by the rising of the piston 8. When the pressure rod 1 is lifted up and reset, the waterproof paper is replaced. In this process, one end of the waterproof paper is held and the waterproof paper is pulled out. If the current waterproof paper has good permeability resistance, the dyed water will remain on the top surface of the waterproof paper. When the waterproof paper is pulled out, the dyed water remaining on the top surface of the waterproof paper will be scraped toward one end of the waterproof paper by the scraper strip 15. Finally, when the waterproof paper is completely pulled out from the No. 1 platform 12, the dyed water on the waterproof paper will be scraped into the water collecting box 16. Since the current detection paper does not contact the dyed water, the detection paper does not need to be replaced. If the current waterproof paper has poor permeability resistance, the dyed water will drip through the waterproof paper onto the detection paper. Therefore, when replacing the waterproof paper, the detection paper needs to be replaced together. Among them, the dyed water retained on the waterproof paper is recovered by the water collecting box 16, and finally part of the dyed water is recycled.
