Description

Technical Field

[0001] The invention relates to the field of detection tools, in particular to a sealing gasket detection annular automatic sampler for alkaline water hydrogen production. Background Art

[0002] There are three main types of existing annular sampling technologies: 1. Annular die sampling is only suitable for materials with thin thickness and poor rigidity. The service life of sealing gaskets made of such materials will be very short; 2. Molding sampling, the tool is thicker, and when the thickness is thicker (≥2mm), it is easy to cause sample damage, deformation and burrs, and the test value is inaccurate; 3. Laser sampling, fast speed and smooth molding, but laser sampling has high energy consumption, slight pollution and is not suitable for gaskets with reflective fillers.

[0003] At the same time, when the existing sampler samples the sealing gasket, in some cases, especially at low temperatures, the gasket material may become brittle and hard, which increases the risk of deformation during the sampling process. When the sampler is feeding the sealing gasket sample material, the edge of the sealing gasket sample material will rub against the cutter. At this time, if the sample material is rigidly pushed by the push rod, the sealing gasket may be damaged during the feeding process.

[0004] Furthermore, when the sampler drives the sampled part to move, the sample material sampled by the sampler may shrink due to factors such as aging of the material of the sealing gasket during manufacturing or storage, changes in the temperature and humidity of the environment, etc. This shrinkage will cause the size of the sample to change, especially when the sample shrinkage rate is large (the shrinkage rate refers to the ratio of the sample size reduction under specific conditions such as temperature, humidity or external force), the sampler fixture that was originally adapted to the sample size will no longer be suitable, resulting in unstable clamping. At this time, some samples will fall during the movement, which is not conducive to the collection and induction of samples. Summary of the invention

[0005] Based on this, it is necessary to provide a sealing gasket detection annular automatic sampler for alkaline water hydrogen production in response to the existing technical problems.

[0024] Thirdly, the device cuts the sample material by means of several groups of outer blades, and several outer blades can be moved so that when the sample is subsequently removed from the sampler, the sample material will not be stuck between the inner blades and the outer blades. At the same time, after the outer blades move, a gap will appear between the outer blades and the edge of the sample material, and this gap can prevent the edge of the sample material from being damaged during the unloading process.

DETAILED DESCRIPTION

[0036] 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.

[0037] refer to Figures 1 to 9 , a sealing gasket detection annular automatic sampler for alkaline water hydrogen production, comprising an oil cylinder 1, a supporting cylinder 2 fixedly connected to the movable end of the oil cylinder 1, a main pressure plate 3 fixedly connected to the lower end of the supporting cylinder 2 and a carrier 4 arranged below the oil cylinder 1, and also comprising a heating silicone pad 5, an inner knife 8, an outer knife 9, a cutting assembly 10, a pushing mechanism and a pressure sensor 6. The heating silicone pad 5 is arranged at the upper end of the carrier 4 and can heat the sample 7 to be sampled. The inner knife 8 is coaxially fixedly connected to the lower end of the supporting cylinder 2. A plurality of outer knives 9 are arranged, and each outer knife 9 is distributed at equal angles along the circumferential direction of the lower end of the main pressure plate 3 and can slide relatively with the main pressure plate 3. The cutting assembly 10 is arranged with The main pressure plate 3 is connected, and the cutting assembly 10 includes an air cooling mechanism 16, a plurality of vacuum suction nozzles 28 and a plurality of vacuum machines 27. The air cooling mechanism 16 is arranged beside the supporting cylinder 2, and the plurality of vacuum suction nozzles 28 are respectively arranged beside the plurality of outer knives 9, and the plurality of vacuum machines 27 are respectively arranged above the plurality of vacuum suction nozzles 28. The pushing mechanism is connected to the supporting cylinder 2, and the pushing mechanism includes a first push rod 33 and a plurality of second push rods 47. The first push rod 33 is arranged coaxially with the inner knife 8, and the plurality of second push rods 47 are respectively arranged beside the plurality of outer knives 9. The pressure sensor 6 is arranged beside the heating silicone pad 5, and can limit the movement of the supporting cylinder 2. The plurality of vacuum machines 27 can be replaced by a vacuum pump and a negative pressure tank, and the negative pressure tank is connected to the plurality of vacuum suction nozzles 28 at the same time, and the vacuum pump is connected to the negative pressure tank and evacuates the negative pressure tank. A heating wire can be arranged in the heating silicone pad 5 to achieve heating.

[0038] When the device is in operation, after the operator places the sample 7 on the upper end of the carrier 4, the heating silicone pad 5 can heat the sample 7 to prevent the sample 7 from breaking during the subsequent cutting process.

[0039] When the cylinder 1 is started, the cylinder 1 will drive the supporting cylinder 2 and the main pressure plate 3 to move downward, and finally the inner knife 8 and the plurality of outer knives 9 will perform circular cutting on the sample 7 on the upper end of the carrier 4, and the sampled part of the sample 7 will be adsorbed by the plurality of vacuum suction nozzles 28. Then, when the device moves, the plurality of vacuum suction nozzles 28 can prevent the sample 7 from falling from the gap between the inner knife 8 and the plurality of outer knives 9. When the sampled sample 7 needs to be unloaded, the vacuum machine 27 stops running, the pushing mechanism starts and pushes the sampled sample 7 out of the device through the first push rod 33 and the second push rod 47.

[0040] When the supporting cylinder 2 and the main pressure plate 3 move downward, the air cooling mechanism 16 will contact the pressure sensor 6, and the pressure sensor 6 will transmit this signal to the controller. The controller uses this data to control the descending range of the supporting cylinder 2 and the main pressure plate 3, that is, the descending range of the inner knife 8 and several outer knives 9.

[0041] In order to improve the accuracy of sampling, the following features are also set:

[0042] The air cooling mechanism 16 also includes a first air cooler 17 and a plurality of second air coolers 18. The first air cooler 17 is arranged inside the supporting cylinder 2 and can cool down the inner knife 8. The supporting cylinder 2 is provided with an air duct that cooperates with the first air cooler 17. The plurality of second air coolers 18 are respectively fixedly arranged beside the plurality of outer knives 9, and the plurality of second air coolers 18 can cool down the plurality of outer knives 9 respectively. When the inner knife 8 and the plurality of outer knives 9 cut and sample the sample 7, if the temperature of the blade itself is too high, the blade may cause local heat deformation or thermal damage to the sample 7 when it contacts the sample 7. The risk of such thermal damage can be reduced by cooling, and the original structure and properties of the sample 7 can be maintained, thereby improving the reliability of the test results. At the same time, lowering the blade temperature can reduce the thermal deformation and thermal stress generated during the cutting process, making the cutting more accurate and smooth. This helps to ensure the accuracy of sampling and reduce analytical errors caused by poor cutting quality.

[0043] In order to cut the sample 7 located inside the inner knife 8, the following features are also specifically set:

[0044] The pushing mechanism also includes a pushing motor 48, a first gear 38, a first gear ring 37, a first screw sleeve 36, a first screw 34, a positioning disc 39 and a first silicone sleeve 35. The pushing motor 48 is fixedly connected to the upper part of the supporting cylinder 2. The positioning disc 39 is arranged at the upper end of the first air cooler 17 and is coaxially fixedly connected to the supporting cylinder 2. The first gear 38 is rotatably arranged at the upper end of the positioning disc 39 and is coaxially fixedly connected to the output end of the pushing motor 48. The first gear ring 37 is coaxially rotatably arranged at the upper end of the positioning disc 39 and meshes with the first gear 38. The first screw sleeve 36 is coaxially fixedly connected to the first gear ring 37. The first screw 34 is threadedly connected to the first screw sleeve 36. The first push rod 33 is coaxially fixedly connected to the lower end of the first screw 34. The first push rod 33 is slidably connected to the lower end of the supporting cylinder 2. The first silicone sleeve 35 is coaxially fixedly connected to the lower end of the first push rod 33. After the push motor 48 is started, the push motor 48 will drive the first gear ring 37 to rotate through the first gear 38, and the first gear ring 37 will drive the first screw 34 to move through the first screw sleeve 36. After the first screw 34 moves, it will drive the first silicone sleeve 35 to move through the first push rod 33. At this time, the sample 7 located inside the inner knife 8 will be pushed down by the first silicone sleeve 35. Since the sampled and tested part is the sample 7 located between the inner knife 8 and the plurality of outer knives 9 (the sample 7 is in the shape of a ring, which is the subsequent test object), the sample 7 located inside the inner knife 8 does not need to worry about being damaged during the feeding process. Furthermore, a first limiting groove is provided on the first push rod 33, and a first limiting platform matched with the first limiting groove is provided on the supporting cylinder 2. The first limiting platform can be slidably arranged in the first limiting groove. Since the first screw 34 is fixedly connected to the first push rod 33, the first screw 34 can be prevented from rotating with the first screw sleeve 36. The first silicone sleeve 35 and the first push rod 33 can rotate relative to each other, so as to avoid wear between the first silicone sleeve 35 and the sample 7 .

[0045] In order to extract the sample 7 between the inner knife 8 and the outer knives 9, the following features are also specifically provided:

[0046] The pushing mechanism also includes a connecting sleeve 40, a second gear ring 41, an assembly gear ring 42, a plurality of second silicone sleeves 43, a plurality of transfer gears 46, a plurality of second screw sleeves 44 and a plurality of second screws 45.

The plurality of second screw sleeves 44 are respectively connected to the plurality of transfer gears 46 coaxially, the plurality of second screw rods 45 are respectively threadedly connected to the plurality of second screw sleeves 44, the plurality of second push rods 47 are respectively slidably connected to the lower end of the main pressure plate 3 through rod seats, the plurality of second push rods 47 are respectively connected to the plurality of second screw rods 45 coaxially, and the plurality of second silicone sleeves 43 are respectively connected to the lower ends of the plurality of second push rods 47. When the first gear 38 rotates, the first gear 38 drives the connecting sleeve 40 to rotate through the second gear ring 41, and the connecting sleeve 40 drives the plurality of transfer gears 46 to rotate through the assembly gear ring 42. The plurality of transfer gears 46 drive the plurality of second screws 45 to move through the plurality of second screw sleeves 44. After the plurality of second screws 45 move, the plurality of second silicone sleeves 43 are driven to move through the plurality of second push rods 47. The plurality of second silicone sleeves 43 push the sample 7 to move. At this time, the sample 7 located between the inner knife 8 and the plurality of outer knives 9 will fall to realize the unloading of the sample 7. Furthermore, each second push rod 47 is provided with a second limiting groove, and the main pressure plate 3 is provided with a second limiting platform matched with the second limiting groove. Each second limiting platform can be slidably arranged in the corresponding second limiting groove. The second push rod 47 is fixedly connected with the corresponding second screw 45, so that the second screw 45 can be prevented from rotating with the second screw sleeve 44. The second silicone sleeve 43 and the corresponding second push rod 47 can rotate relative to each other to avoid causing wear to the sample 7.

[0047] In order to realize the movement of the plurality of outer knives 9, the following features are also specifically provided:

[0048] The cutting assembly 10 also includes a plurality of limit racks 11, a plurality of limit gears 12, a plurality of driven bevel gears 13, a plurality of active bevel gears 14 and a plurality of driving gears 15. The plurality of active gears 15 are rotatably arranged at the upper end of the main pressure plate 3 and mesh with the plurality of transfer gears 46. The plurality of active bevel gears 14 are coaxially fixedly connected with the plurality of active gears 15, the plurality of driven bevel gears 13 are meshed with the plurality of active bevel gears 14, the plurality of limit gears 12 are coaxially fixedly connected with the plurality of driven bevel gears 13, the plurality of limit racks 11 are meshed with the plurality of limit gears 12, and the plurality of limit racks 11 are respectively fixedly connected with the upper ends of the plurality of outer knives 9. During the rotation of the plurality of transfer gears 46, the plurality of transfer gears 46 will respectively drive the plurality of active bevel gears 14 to rotate through the plurality of active gears 15, the plurality of active bevel gears 14 will respectively drive the plurality of limit gears 12 to rotate through the plurality of driven bevel gears 13, and the plurality of limit gears 12 will respectively drive the plurality of outer knives 9 to move through the plurality of limit racks 11.

[0049] The limiting gear 12 is slidably mounted on the main pressure plate 3 , and a plurality of limiting gears 12 are rotatably mounted on the main pressure plate 3 .

[0050] When cutting and sampling the sample 7, the outer knives 9 move toward the direction close to the axis of the supporting cylinder 2, and the outer knives 9 gather together to form a complete circular blade. When cutting the sample 7, the outer knives 9 move away from the axis of the supporting cylinder 2, and the outer knives 9 disperse, and the edge of the sample 7 located between the inner knife 8 and the outer knives 9 will be separated from the outer knives 9 to prevent the edge of the sample 7 from being damaged when the second silicone sleeves 43 push the sample 7 to move.

[0051] In order to realize the function of the vacuum nozzle 28, the following features are also specifically provided:

[0052] The cutting assembly 10 also includes a plurality of air guide tubes 26, a plurality of sliding gaskets 29, a plurality of sliding ducts 30, a plurality of air relief mechanisms 19 and a plurality of sliding springs 31. The plurality of air guide tubes 26 are respectively fixedly arranged on the sides of the assembly gear ring 42. The upper ends of the plurality of air guide tubes 26 are respectively fixedly connected to the output ends of the plurality of vacuum machines 27. The plurality of sliding ducts 30 are respectively connected to the lower dynamic seals of the plurality of air guide tubes 26. The plurality of vacuum suction nozzles 28 are respectively fixedly connected to the lower ends of the plurality of sliding ducts 30. The plurality of sliding gaskets 29 are respectively fixedly connected coaxially with the plurality of sliding ducts 30. The plurality of sliding springs 31 are respectively sleeved on the outside of the plurality of sliding ducts 30. The upper ends of the plurality of sliding springs 31 are respectively fixedly connected to the main pressure plate 3, and the lower ends are respectively fixedly connected to the plurality of sliding gaskets 29. The plurality of air relief mechanisms 19 are respectively arranged on the sides of the plurality of air guide tubes 26 and are connected to the air guide tubes 26. When the vacuum suction nozzle 28 needs to adsorb the sample 7, the plurality of vacuum machines 27 are started to adsorb the sample 7 through the plurality of air guide tubes 26, the plurality of sliding guide tubes 30 and the plurality of vacuum suction nozzles 28 in sequence. During this process, the plurality of sliding springs 31 can ensure that the samples 7 with different shrinkage rates can still be pressed when being adsorbed, so as to prevent the samples 7 from being deformed and separated from the plurality of vacuum suction nozzles 28.

[0053] Furthermore, the upper end of the sliding guide tube 30 can be slidably inserted into the lower end of the air guide tube 26 to form a telescopic tube. The telescopic tube can also directly adopt an existing telescopic tube.

[0054] In order to supplement the specific structure of the deflation mechanism 19, the following features are also specifically provided:

[0055] The deflation mechanism 19 includes a power gear 20, a deflation gear 21, a deflation rack 22 and a deflation circular pipe 23. The power gear 20 is rotatably arranged beside the assembly gear ring 42 and meshes with the assembly gear ring 42. The deflation gear 21 is coaxially fixedly connected to the power gear 20. The deflation rack 22 is slidably arranged above the main pressure plate 3 through a gear seat and meshes with the deflation gear 21. The deflation circular pipe 23 is dynamically sealed with the air guide pipe 26, and the deflation circular pipe 23 is fixedly connected to the deflation rack 22. When the assembly gear ring 42 rotates, the assembly gear ring 42 will also drive the plurality of power gears 20 to rotate. After the plurality of power gears 20 rotate, they will respectively drive the plurality of air relief racks 22 to move through the plurality of air relief gears 21. After the plurality of air relief racks 22 move, they will drive the plurality of air relief tubes 23 to move. After the plurality of air relief tubes 23 move, the air in the air guide tube 26 can be released to prevent the plurality of vacuum nozzles 28 from still adsorbing the sample 7 after the plurality of vacuum machines 27 stop working.

[0056] In order to release the air in the air guide tube 26 after the deflation tube 23 moves, the following features are also specifically provided:

[0057] A first air leakage hole 24 and a second air leakage hole 25 are formed on the plurality of air leakage round tubes 23, respectively. The first air leakage hole 24 is arranged on the side of the air leakage round tube 23 close to the vacuum machine 27, the first air leakage hole 24 is arranged in the middle of the air leakage round tube 23, the second air leakage hole 25 is arranged on the side of the air leakage round tube 23 away from the vacuum machine 27, and the second air leakage hole 25 is arranged on the end of the air leakage round tube 23 away from the air leakage rack 22. Fig. 9 When the deflation circular tube 23 does not move, the air flow in the air guide tube 26 will not leak out. However, when the deflation circular tube 23 moves, the air flow in the air guide tube 26 will flow out from the second air leakage hole 25 through the first air leakage hole 24, thereby quickly releasing the air in the air guide tube 26.

[0058] The working principle of the device is that when the device is in operation, after the operator places the sample 7 on the upper end of the carrier 4, the heating silicone pad 5 can heat the sample 7 to prevent the sample 7 from breaking during the subsequent cutting process.

[0059] When the oil cylinder 1 is started, the oil cylinder 1 will drive the supporting cylinder 2 and the main pressure plate 3 to move downward, and finally the inner knife 8 and several outer knives 9 will perform circular cutting on the sample 7 on the upper end of the carrier 4, and the sampled part of the sample 7 will be adsorbed by several vacuum nozzles 28. When it is necessary to unload the sample 7, the vacuum machine 27 stops running, and the pushing motor 48 is started to push the sample 7 out of the device through the first push rod 33 and the second push rod 47.

[0060] During the movement of the second push rods 47, the limiting gears 12 drive the outer knives 9 to move through the limiting racks 11. It can be seen that when cutting and sampling the sample 7, the outer knives 9 move toward the axis of the supporting cylinder 2, and the outer knives 9 gather to form a complete circular blade, and when cutting the sample 7, the outer knives 9 move away from the axis of the supporting cylinder 2, and the outer knives 9 disperse, and the edge of the sample 7 between the inner knife 8 and the outer knives 9 is separated from the outer knives 9 to prevent the edge of the sample 7 from being damaged when the second silicone sleeves 43 push the sample 7 to move.

[0061] In order to prevent the vacuum nozzles 28 from still adsorbing the sample 7 after the vacuum machines 27 stop working, when the pusher motor 48 starts and drives the assembly gear ring 42 to rotate, the air leakage tubes 23 will move to release the air in the air guide tube 26 through the first air leakage hole 24 and the second air leakage hole 25. At this time, the second air leakage hole 25 moves to the outside of the air guide tube 26.

[0062] When the supporting cylinder 2 and the main pressure plate 3 move downward, the second air cooler 18 located above the pressure sensor 6 will resist the pressure sensor 6. The pressure sensor 6 transmits this signal to the controller, and the controller uses this data to control the descending amplitude of the supporting cylinder 2 and the main pressure plate 3, that is, the cutting amplitude of the inner knife 8 and several outer knives 9 on the sample 7.

[0063] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
