Description

Technical Field

[0001] The utility model belongs to the technical field of aerogel felt coil thickness measurement, in particular to a continuous thickness measuring mechanism and a thickness measuring device. Background Art

[0002] Existing aerogel felt sheets are usually made by cutting aerogel felt coils, and the production process is: unwinding the aerogel felt coil - slitting - thickness measurement - packaging. The aerogel felt sheets after slitting need to be measured by staff using a special thickness gauge. Single-piece measurement not only takes a long time but can only reflect the local thickness data of the sheet. On the one hand, due to the large number of aerogel felt sheets, a certain sampling ratio is often used to judge whether they are qualified, which has low production efficiency and poor economy. On the other hand, the measured aerogel felt sheet thickness data is discontinuous, and the scattered thickness data cannot reflect the actual thickness of the aerogel felt sheet. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a continuous thickness measuring mechanism, which moves the thickness measuring process forward, measures the thickness while unwinding, and continuously collects the thickness data of the aerogel felt coil in real time to achieve continuous thickness measurement. In addition, the present invention also provides a thickness measuring device.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by a continuous thickness measuring mechanism of the present invention is:

[0005] A continuous thickness measuring mechanism, comprising:

[0006] Mounting base, used to fix on the rack;

[0007] A displacement sensor is fixed on the mounting base, and the displacement sensor includes a detection rod that can be extended and retracted up and down;

[0008] A measuring block is provided below the mounting base, and a guiding telescopic structure is provided between the mounting base and the measuring block in the vertical direction so that the measuring block can move up and down relative to the mounting base when the thickness of the structure being measured changes;

[0009] The lower end of the detection rod is in pressing contact with the measuring block, so that when the measuring block moves up and down, the length of the detection rod changes to obtain continuous thickness data.

[0010] Beneficial effect: When measuring the thickness of flexible materials, since the materials will deform under pressure, it is usually necessary to measure the thickness of the material to be measured under a certain pressure. A continuous thickness measuring mechanism of the present invention is used to measure the thickness of flexible materials such as glass fiber felt, ceramic fiber felt, pre-oxidized silk fiber felt or aerogel felt composite fiber felt. With the continuous thickness measuring mechanism of the present invention, when the material to be measured passes under the measuring block, the measuring block is pressed on the material to be measured under the action of gravity. If the thickness of the material to be measured changes, the measuring block will move up and down. At this time, the guide telescopic structure will expand and contract in the vertical direction corresponding to the position of the measuring block, and the detection rod of the displacement sensor pressing on the measuring block will expand and contract, thereby measuring the thickness of the material to be measured according to the change in the length of the displacement sensor detection rod. The thickness measuring mechanism of the present invention can continuously measure the thickness of the material to be measured in real time. The measuring block presses the material to be measured on the pad with a certain pressure, and continuously measures the thickness of the flexible material with a fixed pressure, forming a large amount of measurement data for reference. In addition, the thickness measuring mechanism is automatic detection, which reduces the number of staff measuring the thickness and reduces labor costs.

[0011] Furthermore, the measuring block includes a T-shaped probe base and a measuring head fixed to the lower end of the probe base. Two guiding telescopic structures are provided, and the two guiding telescopic structures are respectively placed on both sides of the displacement sensor.

[0012] Beneficial effects: The measuring block includes a T-shaped probe base and a measuring head fixed at the lower end of the probe base. On the one hand, the T-shaped probe base can be connected to the mounting base through a guide telescopic structure. The two guide telescopic structures are respectively located on both sides of the displacement sensor, making the measuring block more stable during the up and down movement; on the other hand, setting the measuring block into a split T-shaped probe base and a measuring head fixed at the lower end of the probe base can achieve the distinction between the material of the measuring head and the material of the probe base, thereby ensuring the wear resistance of the measuring head.

[0013] Furthermore, the guiding telescopic mechanism includes a guiding column fixed on the mounting base and a linear bearing fixed on the probe base, and the guiding column is adapted to slide upward and downward along the linear axis.

[0014] Beneficial effect: The guide column fixed on the mounting base can guide the linear bearing fixed on the probe base, so that the probe base can move up and down along the guide column.

[0015] It also includes a clamping unit, which includes a rotating shaft, a swivel, a pushing connecting rod and a pressure block. The rotating shaft is rotatably mounted on the frame, the swivel is sleeved on the rotating shaft and fixedly connected to the rotating shaft, one end of the pushing connecting rod is hinged to the swivel, and the other end is hinged to the pressure block to form a structure in which the rotating shaft rotates to drive the swivel and the pushing connecting rod to rotate to achieve lifting or pressing down of the pressure block.

[0016] Beneficial effect: The pressing unit can flatten the aerogel felt roll before thickness measurement to prevent the thickness measurement accuracy from being affected by the warping of the felt.

[0017] Furthermore, the clamping unit also includes a connecting plate and a fixed ring. The connecting plate is fixed on the mounting base, the fixed ring is sleeved on the rotating shaft and is rotatably connected to the rotating shaft, and the fixed ring and the pressure block are hingedly connected through a follower connecting rod; when the rotating shaft rotates, the rotating ring rotates with the rotating shaft, and the pressure block is driven to move by pushing the connecting rod. The fixed ring is fixed relative to the frame, and the pressure block drives the follower connecting rod to rotate around the hinge point with the fixed ring to control the angle of the pressure block and keep the pressure block vertical.

[0018] Beneficial effect: The arrangement of the fixed ring and the follower connecting rod can keep the pressing block in a vertical state during the up and down movement, and the up and down movement of the pressing block is more stable.

[0019] Furthermore, the clamping unit includes two fixed rings and one rotating ring, and the two fixed rings are respectively arranged on both sides of the rotating ring. An avoidance hole for the pushing connecting rod to pass through is opened on the connecting plate, and two follower connecting rods are arranged in parallel at intervals above and below, so that the pressure block, fixed ring and follower connecting rod form a parallelogram structure.

[0020] Beneficial effect: The follower connecting rods corresponding to the two fixed rings are located on both sides of the pressing block, forming parallelogram structures on both sides of the pressing block, making the up and down movement of the pressing block more stable.

[0021] The pressure block includes a horizontally arranged pressure plate, which includes a linkage body, a first plate body and a second plate body. The linkage body is connected to the push rod. The first plate body and the second plate body are both connected to the linkage body and are arranged at intervals. The measuring block is arranged between the first plate body and the second plate body.

[0022] Beneficial effect: The pressing block includes a horizontally arranged pressing plate, so that the pressing block provides a larger pressing surface for the aerogel felt, and the flattening effect is better.

[0023] A horizontally arranged lifting screw is fixed on the measuring head base. The lifting screw is arranged above the pressing block so that the measuring head can be lifted by pushing the lifting screw when the pressing block is lifted.

[0024] Beneficial effect: With the setting of the lifting screw, when the front end of the aerogel felt roll enters the thickness measuring mechanism, the rotating shaft rotates, driving the pressure block to move upward. When the pressure block is lifted, the lifting screw is pushed to lift the probe block, making it easier for the felt roll to enter, thereby measuring the material thickness through the probe block and the displacement sensor.

[0025] According to another aspect of the present application, the present application further provides a thickness measuring device, comprising:

[0026] The continuous thickness measurement mechanism described above;

[0027] A frame is used to install a continuous thickness measuring mechanism, wherein a plurality of continuous thickness measuring mechanisms are arranged at intervals in the extending direction of the frame;

[0028] The guide connecting plate is fixed on the frame and comprises a guide plate body which is tilted and guides the measured structure to move toward the continuous thickness measuring mechanism.

[0029] Beneficial Effects: When measuring the thickness of flexible materials, since the materials will deform under pressure, it is usually necessary to measure the thickness of the material under a certain pressure. The thickness measuring device of the utility model is used to measure the thickness of flexible materials such as glass fiber mat, ceramic fiber mat, pre-oxidized silk fiber mat or aerogel composite fiber mat. With the continuous thickness measuring device of the present invention, when the material to be measured passes under the measuring block, the measuring block is pressed on the material to be measured under the action of gravity. If the thickness of the material to be measured changes, the measuring block will move up and down. At this time, the guide telescopic structure corresponds to the position of the measuring block in the up and down directions, and the detection rod of the displacement sensor pressing on the measuring block is also telescopic, thereby measuring the thickness of the material to be measured according to the length change of the detection rod of the displacement sensor. The thickness measuring mechanism of the present invention can continuously measure the thickness of the material to be measured in real time. The measuring block presses the material to be measured against the pad with a certain pressure, and continuously measures the thickness of the flexible material with a fixed pressure, forming a large amount of measurement data for reference. In addition, the thickness measuring mechanism is automatic detection, which reduces the number of staff for thickness measurement and reduces labor costs. The provision of the guide connecting plate in the measuring device facilitates the guidance of the measuring block when the material to be measured enters under the measuring block, so that the material to be measured can smoothly enter under the measuring block.

[0030] Furthermore, the frame includes two vertical plates arranged at intervals, an upper crossbeam fixed between the vertical plates, and a lower crossbeam fixed between the vertical plates. The lower crossbeam is arranged below the upper crossbeam, and the lower crossbeam includes two spaced apart beams. The pad is fixed between the two lower crossbeams. The pad is arranged adjacent to the guide plate body so that the guide plate body and the pad form a continuous guide support surface.

[0031] Beneficial effects: The frame structure is highly stable, and the pad is adjacent to the guide plate body so that the guide plate body and the pad form a continuous guide support surface, so that the material to be measured can smoothly enter under the measuring block along the guide support surface.

DETAILED DESCRIPTION

[0042] The following is a further detailed description of a continuous thickness measuring mechanism and a thickness measuring device of the present invention in conjunction with the accompanying drawings and specific embodiments:

[0043] Specific embodiment 1: Figure 1As shown, a continuous thickness measuring mechanism of the present invention includes a thickness measuring unit 10, which is used to measure the thickness of flexible materials such as glass fiber mat, ceramic fiber mat, pre-oxidized silk fiber mat or aerogel composite fiber mat. The thickness measuring unit 10 includes a mounting base 11 fixed on a frame 30, and a displacement sensor 12 is fixed on the mounting base 11. The displacement sensor 12 includes a detection rod that can be extended and retracted up and down. In this embodiment, the displacement sensor 12 is a contact displacement sensor. A measuring block 13 is installed below the mounting base 11, and a guide telescopic structure 14 is provided between the mounting base 11 and the measuring block 13 in the up and down directions. When the thickness of the structure to be measured changes, the guide telescopic structure 14 is extended and retracted, so that the measuring block 13 moves up and down relative to the mounting base 11.

[0044] The measuring block 13 includes a T-shaped probe base 131 and a measuring head 132 fixed to the lower end of the probe base 131. The T-shaped probe base 131 includes a horizontal cross block and a vertical block vertically fixed on the horizontal cross block. The measuring head 132 is fixed to the bottom end of the vertical block. In this embodiment, the measuring head 132 is in direct contact with the aerogel felt coil. The measuring head 132 is made of a material with good wear resistance, such as polyethylene, polystyrene, polytetrafluoroethylene, etc.

[0045] There are two guiding telescopic structures 14, which are respectively located on both sides of the displacement sensor 12. Specifically, the guiding telescopic structures 14 are located at both ends of the horizontal cross block of the T-shaped probe base 131. That is, when the measuring block 13 moves up and down, the two guiding telescopic structures 14 guide it on both sides of the measuring block 13 to ensure that the measuring block 13 moves up and down more smoothly.

[0046] The guiding telescopic structure 14 includes a guiding column 141 fixed on the mounting base 11 and a linear bearing 142 fixed on the probe base 131 . The guiding column 141 and the linear bearing 142 are adapted to guide and slide up and down.

[0047] The thickness measuring unit 10 also includes a pad, which is horizontally fixed on the frame and arranged correspondingly above and below the measuring block. The pad is used to support the material to be measured so as to measure the thickness of the material to be measured when the measuring block presses down on the structure to be measured.

[0048] The lower end of the detection rod of the displacement sensor 12 presses against the measuring block 13. As the measuring block 13 moves up and down in response to changes in the thickness of the aerogel felt coil, the length of the detection rod changes, thereby obtaining continuous thickness data for the aerogel felt coil. In this embodiment, the structure and detection principle of the contact displacement sensor 12 are conventional and will not be described in detail here. The thickness measurement unit 10 measures the thickness of the aerogel felt coil in real time and automatically archives the measurement data.

[0049] In order to make the aerogel felt coil smoother before it enters the measuring block 13 for thickness measurement, in this embodiment, the continuous thickness measurement mechanism also includes a pressing unit 20, which includes a rotating shaft 21, a rotating ring 22, a pushing link 23, and a pressing block 24. The rotating shaft 21 is rotatably mounted on the frame, the rotating ring 22 is sleeved on the rotating shaft and fixedly connected to the rotating shaft 21, and one end of the pushing link 23 is hinged to the rotating ring and the other end is hinged to the pressing block, forming a structure in which the rotating shaft 21 rotates to drive the rotating ring 22 and the pushing link 23 to rotate, thereby lifting or pressing the pressing block 24. In this embodiment, the rotating ring 22 is fixed to the rotating shaft 21 by a set screw 221, so that the rotating ring 22 can rotate as the rotating shaft 21 rotates.

[0050] In order to further ensure the stability of the pressing block 24 during the lifting or pressing process, in this embodiment, the pressing unit 20 includes a connecting plate 25 and a fixed ring 26. The connecting plate 25 is fixed to the mounting base 11. The fixed ring 26 is sleeved on the rotating shaft 21 and rotatably connected to the rotating shaft. The fixed ring and the pressing block are hingedly connected by a follower link 27. That is, one end of the follower link 27 is hingedly connected to the fixed ring 26, and the other end of the follower link 27 is hingedly connected to the pressing block 24. When the rotating shaft 21 rotates, the rotating ring 22 rotates with the rotating shaft 21, and the pressing block 24 is driven to move by the push link 23. The fixed ring 26 is fixed relative to the frame, and the pressing block 24 drives the follower link 27 to rotate around the hinge point with the fixed ring 26 to control the angle of the pressing block 24 and keep the pressing block 24 vertical.

[0051] In this embodiment, the clamping unit 20 includes two fixed rings 26 and a rotating ring 22. The two fixed rings 26 are respectively arranged on both sides of the rotating ring. An avoidance hole for the push link 23 to pass through is opened on the connecting plate 25. Two follower links 27 are arranged in parallel and spaced apart above and below, so that the pressure block 24, the fixed ring 26, and the follower link 27 form a parallelogram structure. When the rotating shaft 21 drives the rotating ring 22 and the push link 23 to rotate, thereby driving the pressure block 24 to move up and down, the follower link 27 rotates around the hinge point of the fixed ring 26 as the pressure block 24 moves, thereby increasing the stability of the movement of the pressure block 24.

[0052] The pressing block 24 includes a linkage, a first plate 241, and a second plate 242. The linkage is connected to the push rod. The first plate 241 and the second plate 242 are both connected to the linkage and spaced apart. The measuring block 13 is disposed between the first plate 241 and the second plate 242. On the one hand, the pressing surface of the pressing block 24 on the aerogel felt coil is increased. On the other hand, the measurement block 13 is disposed between the first plate 241 and the second plate 242. The surrounding structure of the aerogel felt coil to be measured can be flattened by the first plate 241 and the second plate 242, thereby reducing the measurement error caused by the warping of the aerogel felt coil to be measured and making the measured thickness of the aerogel felt coil more accurate.

[0053] A horizontally mounted lifting screw 15 is fixed to the probe base 131. By lifting the lifting screw 15 upward, the linear bearing 142 on the probe base 131 moves along the guide post 141, causing the probe base 131 to move upward, facilitating the entry of the aerogel felt coil beneath the continuous thickness measurement mechanism. In this embodiment, the lifting screw is positioned above the pressure block, so that when the pressure block is lifted, the lifting screw pushes against the lifting screw, raising the measuring head.

[0054] In this embodiment, the pressing unit 20 flattens the aerogel felt coil to prevent the warping of the aerogel felt coil from causing errors in thickness measurement. When measuring the thickness of the aerogel felt coil, the rotating shaft 21 rotates, and the rotating shaft 21 moves with the swivel 22 and the push rod 23 to move the pressure block 24 upward. When the pressure block 24 is lifted, the bolt is lifted upward to make the linear bearing 142 on the probe base 131 move along the guide column 141, and the probe base 131 moves upward to facilitate the entry of the aerogel felt coil.

[0055] Specific embodiment 2: A thickness measuring device 1 of the present invention includes a frame 30 and a continuous thickness measuring mechanism fixed to the frame 30. Multiple continuous thickness measuring mechanisms are spaced apart along the extension direction of the frame 30. The frame 30 includes two spaced-apart vertical plates 31, an upper crossbeam 32 fixed between the vertical plates 31, and a lower crossbeam 33 fixed between the vertical plates 31. The lower crossbeam 33 is disposed below the upper crossbeam 32 and includes two spaced-apart lower crossbeams 33. A pad 34 is fixed between the two lower crossbeams 33. In this embodiment, the pad 34 is disposed below the measuring block 13 to support the aerogel felt coil being measured and serves as a reference surface for thickness measurement. Since the pad 34 directly contacts the aerogel felt coil, it is made of a wear-resistant material, such as polyethylene, polystyrene, or polytetrafluoroethylene. In this embodiment, the mounting base 11 of the thickness measuring unit 10 is fixed to the upper crossbeam 32.

[0056] In order to allow the aerogel felt coil to smoothly enter the thickness measuring device, in this embodiment, a guide connecting plate 35 is fixed to the frame 30. The guide connecting plate 35 includes an inclined guide plate body that guides the measured structure to move toward the continuous thickness measuring mechanism. The pad is arranged adjacent to the guide plate body so that the guide plate body and the pad form a continuous guide support surface.
