Description

Technical Field

[0002] Graphite soft felt is a soft material made of graphite fiber. It has good high temperature resistance, thermal insulation, corrosion resistance and low thermal conductivity. Graphite soft felt is often used in high temperature industrial fields, such as metallurgy, chemical industry, solar energy, nuclear industry, etc. It can be used as thermal insulation material, sealing material, etc. It is also used in some scientific research experimental devices.

[0003] The graphite soft felt is needle-punched to make the graphite fibers interweave with each other to initially form a felt structure. The felt is then heat-treated in a high-temperature environment to remove impurities and increase the degree of graphitization. Finally, the graphite soft felt is trimmed and inspected to ensure that the quality meets the requirements. The thickness needs to be tested during the inspection stage to ensure the continuity and uniformity of the thickness of the graphite soft felt. The existing inspection uses multi-point inspection, which cannot fully inspect the surface of the graphite soft felt and is prone to omissions, resulting in inconsistent thickness in some parts of the graphite soft felt.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0031] Specifically, the edge of the graphite felt is pulled and laid on the conveyor belt 11 by the pulling mechanism 2, and then the flattening mechanism 3 is controlled to press on the graphite felt, and the continuous conveying and detection operation of the graphite felt is realized when the conveyor belt 11 rotates.

[0032] like Figure 5 , Figure 6 As shown, the contact detection mechanism 4 includes a mounting shaft 40 connected to the side frame 10, the mounting shaft 40 is perpendicular to the moving direction of the conveyor belt 11, the mounting shaft 40 is evenly provided with mounting plates 41, the circumference of the mounting plates 41 is evenly provided with telescopic shafts 42, the end of the telescopic shaft 42 is connected to a ring frame 43, the upper side of the mounting shaft 40 is provided with an intermediate plate 47, the intermediate plate 47 is fixedly connected to the side frame 10, both sides of the ring frame 43 are provided with annular matching grooves 44, a lifting frame 45 is inserted into the intermediate plate 47, the lifting frame 45 is buckled on both sides of the ring frame 43, matching blocks 46 are provided on both sides of the lifting frame 45, the matching blocks 46 and the annular matching grooves 44 cooperate with each other, an intermediate plate 47 is provided on the top of the lifting frame 45, and a marking mechanism 5 is provided between the intermediate plate 47 and the lifting frame 45.

[0033] Specifically, the annular frame 43 is movably installed by using the mounting plate 41 and the telescopic shaft 42. When the graphite soft felt moves forward driven by the flattening mechanism 3 and the conveyor belt 11, the lowest point of the annular frame 43 contacts the surface of the graphite soft felt. By adjusting the height of the mounting shaft 40 at the center of the mounting plate 41, the center of the annular frame 43 is coaxial with the mounting shaft 40 when the graphite soft felt is at a standard thickness. When there is a portion on the surface of the graphite soft felt that exceeds the thickness standard, the annular frame 43 will jump upward with the movement of the graphite soft felt. Since the matching blocks 46 at both ends of the lifting frame 45 cooperate with the annular matching grooves 44, the jumping of the annular frame 43 will drive the lifting frame 45 to move synchronously. The movement of the lifting frame 45 and the marking mechanism 5 are used to continuously detect and record the thickness change of the graphite soft felt.

[0034] Further, such as Figure 6 , Figure 8 As shown, the marking mechanism 5 includes a fixed plate 2 31 fixedly arranged on both sides of the middle plate 47, and a mounting frame 500 is symmetrically arranged on the fixed plate 2 31 close to the release cylinder 12. A tape roller 501 is rotatably installed between the mounting frames 500, and the tape roller 501 is sequentially provided with a tape roll 502 corresponding to the annular frame 43. A positioning roller 51 is vertically installed between the middle plate 47 and the lifting frame 45. A transparent tape 50 is wound on the tape roller 501, and a plurality of gathering rollers 54 are arranged on the fixed plate 2 31 away from the side of the tape roller 501. The transparent tape 50 passes through the positioning roller 51 and the gathering roller 54 and is pressed together. The lifting frame 45 is provided with a horizontal frame 48 at the upper end of the middle plate 47, and a marking pen 49 is arranged on the horizontal frame 48. The marking pen 49 is in contact with the side of the transparent tape 50, and the transparent tape 50 between the gathering rollers 54 is connected with a driving component 55.

[0035] Specifically, the driving assembly 55 drives the gathering roller 54 to rotate, so that the compressed transparent tape 50 is continuously pulled out from the tape roll 502, and the pulled transparent tape 50 contacts the marking pen 49, and the jumping process of the lifting frame 45 is recorded on the transparent tape 50. The thickness change process of the graphite soft felt is judged by observing the marking line on the compressed transparent tape 50.

[0036] Further, such as Figure 4 As shown, the flattening mechanism 3 includes swing rods 30 respectively arranged on both sides of the mounting shaft 40, the swing rod 30 is rotatably installed between the end of the mounting shaft 40, a telescopic cylinder 32 is arranged at the bottom of the fixed plate 31, the telescopic cylinder 32 is connected to the clamping frame 33, a matching slide groove 34 is arranged on the swing rod 30, the clamping frame 33 and the matching slide groove 34 are slidably installed, a pressure roller 1 35 is rotatably installed between the swing rods 30 on the side close to the release cylinder 12, and a pressure roller 2 39 is rotatably installed between the swing rods 30 on the side away from the release cylinder 12, and the driving assembly 55 is connected to the pressure roller 2 39.

[0037] Specifically, the swing rod 30 is controlled by the telescopic cylinder 32 to rotate around the mounting shaft 1 40, and the pressure roller 1 35 and the pressure roller 2 39 on both sides are respectively driven to press against the conveyor belt 11, and the graphite felt is smoothed and pressed, so as to ensure the data accuracy when the contact detection mechanism 4 and the graphite felt are contacted and detected. At the same time, through the pressing contact between the pressure roller 2 39 and the graphite felt on the conveyor belt 11, the power of the conveyor belt 11 is transmitted from the graphite felt to the pressure roller 2 39, and then transmitted to the transparent tape 50 by the driving component 55, so that the transparent tape 50 is continuously released and pulled out from the tape roll 502, and the thickness change is marked in combination with the marking mechanism 5.

[0038] Further, such as Fig. 9 , Fig.10 As shown, the second pressure roller 39 is rotatably installed between the second mounting shaft 551 and the edge of the swing rod 30, the driving assembly 55 includes a spring rod 550 arranged on the swing rod 30, a bevel gear 552 and a connecting frame 554 are coaxially installed on the second mounting shaft 551, a spring rod 558 is connected to the upper end of the connecting frame 554, and the spring rod 558 is connected to the edge of the second top fixing plate 31, a positioning frame 555 is arranged on the connecting frame 554, a bevel gear 553 is rotatably installed on the positioning frame 555, and the bevel gear 552 is coaxially installed on the second mounting shaft 551. 2 is meshed with the bevel gear 2 553, a telescopic transmission shaft 557 is provided on the rotation axis of the bevel gear 2 553, a pulley 1 559 is rotatably installed on the bottom of the fixed plate 2 31, a gathering flange 5513 is provided on the middle edge of the fixed plate 2 31, a pressure wheel 5511 is rotatably installed on the gathering flange 5513, the transparent tape 50 passes through the pressure wheels 5511 and moves forward, a pulley 2 5512 is provided at the bottom of the pressure wheel 5511, and a transmission belt 5510 is provided between the pulley 2 5512 and the pulley 1 559.

[0039] Specifically, the pressure roller 2 39 presses the graphite felt against the conveyor belt 11. When the conveyor belt 11 moves, the graphite felt and the pressure roller 2 39 are driven to rotate. While the pressure roller 2 39 rotates, the telescopic transmission shaft 557 is driven to rotate by the bevel gear 1 552 and the bevel gear 2 553. Combined with the pulley 1 559 and the pulley 2 5512, the power is transmitted to the pressure wheel 5511, thereby conveying the transparent tape 50 between the pressure wheels 5511, and realizing the continuous release of the transparent tape 50 on the tape roll 502. In order to ensure reliable transmission of power when the pressure roller 2 39 detects graphite soft felt of different thicknesses, a spring rod 1 550 is provided on the swing rod 30, and the connecting frame 554 is connected to the top fixed plate 2 31 through a spring rod 2 558. When the thickness of the detected graphite soft felt changes, reliable compression between the pressure roller 2 39 and the conveyor belt 11 can be ensured, and the power of the pressure roller 2 39 can be transmitted to the clamping wheel 5511 in combination with the driving assembly 55.

[0040] Furthermore, one side of the transparent tape 50 is provided with adhesive, the marking pens 49 have different colors, and the marking pens 49 are provided on the side of the transparent tape 50 that does not contain adhesive.

[0041] Specifically, adhesive is provided on one side of the transparent tape 50 to facilitate the transparent tape 50 to be attached together under the action of the gathering roller 54 and the clamping wheel 5511. At the same time, the colors of the marking pens 49 are different from each other, which makes it easy to observe the parts where the thickness of the graphite soft felt changes.

[0042] Further, such as Figure 4 As shown, a mounting roller 36 is rotatably mounted between the swing rods 30 on the side away from the release cylinder 12 , a leveling knife 37 is provided on the mounting roller 36 , and the mounting roller 36 is connected to a second motor 38 .

[0043] Specifically, the portion of the graphite soft felt whose thickness exceeds the standard is cut off by the leveling knife 37, and the height of the edge of the leveling knife 37 is controlled by the motor 2 38 to adapt to the cutting process of graphite soft felts with different thicknesses.

[0044] Further, such as Figure 7 As shown, a vertical slot 100 is provided on the side frame 10, a matching slider 411 is slidably installed in the vertical slot 100, a mounting flange 410 is provided on the top of the vertical slot 100, a lifting motor 412 is provided on the mounting flange 410, the mounting shaft 40 is rotationally connected to the matching slider 411, and the output shaft of the lifting motor 412 is rotationally installed with the end of the mounting shaft 40.

[0045] Specifically, the lifting motor 412 controls the movement of the matching slider 2 411 in the vertical slot 100, thereby adjusting the height of the mounting shaft 1 40, and further adjusting the overall height of the contact detection mechanism 4 to adapt to the surface contact detection of graphite soft felts of different thicknesses.

[0046] Further, such as Figure 2 As shown, the pulling mechanism 2 includes a mounting groove 20 arranged on one side of the side frame 10, a matching slider 21 is slidably installed in the mounting groove 20, a fixing plate 25 is rotatably installed on one end of the matching slider 21 toward the side frame 10, the edge of the graphite soft felt is fixedly installed on the surface of the fixing plate 25, a rack 26 is arranged on the edge of the mounting groove 20, a connecting plate 22 is arranged on the matching slider 21, a motor 24 is fixedly arranged on the connecting plate 22, the motor 24 is connected to a driving gear 23, and the driving gear 23 and the rack 26 are meshed with each other.

[0047] Specifically, when in use, the fixing plate 25 is pulled out from the edge of the side frame 10, rotated to a position perpendicular to the side frame 10 and locked, and the edge of the graphite soft felt is fixed on the fixing plate 25. The motor 24 drives the driving gear 23 and the rack 26 to engage with each other, thereby driving the matching slider 21 and the fixing plate 25 to move in the installation slot 20, and then driving the graphite soft felt to enter the bottom of the contact detection mechanism 4 and the flattening mechanism 3, which is convenient for subsequent flattening processing and contact detection operations.

[0048] Further, such as Figure 3 As shown, a support roller 110 is installed on the rotating rod between the annular frame 43 and the conveyor belt 11 directly below the pressure roller 1 35 and the pressure roller 2 39.

[0049] The working principle of the embodiment of the present invention is: like Figure 1-Figure 10 As shown, the annular frame 43 is movably installed by using the mounting plate 41 and the telescopic shaft 42. When the graphite soft felt moves forward driven by the flattening mechanism 3 and the conveyor belt 11, the lowest point of the annular frame 43 contacts the surface of the graphite soft felt. By adjusting the height of the mounting shaft 40 at the center of the mounting plate 41, the center of the annular frame 43 is coaxial with the mounting shaft 40 when the graphite soft felt is at a standard thickness. When there is a portion on the surface of the graphite soft felt with excessive thickness, the annular frame 43 will jump upward with the movement of the graphite soft felt. Since the matching blocks 46 at both ends of the lifting frame 45 cooperate with the annular matching grooves 44, the jumping of the annular frame 43 will drive the lifting frame 45 to move synchronously. The movement of the lifting frame 45 and the marking mechanism 5 are used to continuously detect and record the thickness change of the graphite soft felt. The swing rod 30 is controlled by the telescopic cylinder 32 to rotate around the mounting shaft 1 40, and the pressure rollers 1 35 and 2 39 on both sides are driven to press against the conveyor belt 11, and the graphite felt is smoothed and pressed, so as to ensure the data accuracy when the contact detection mechanism 4 and the graphite felt are in contact. At the same time, through the pressing contact between the pressure roller 2 39 and the graphite felt on the conveyor belt 11, the power of the conveyor belt 11 is transmitted from the graphite felt to the pressure roller 2 39, and then transmitted to the transparent tape 50 by the driving component 55, so that the transparent tape 50 is continuously released and pulled out from the tape roll 502, and the thickness change is marked in combination with the marking mechanism 5. The pressure roller 2 39 presses the graphite felt against the conveyor belt 11. When the conveyor belt 11 moves, the graphite felt and the pressure roller 2 39 are driven to rotate. While the pressure roller 2 39 rotates, the telescopic transmission shaft 557 is driven to rotate by the bevel gear 1 552 and the bevel gear 2 553. Combined with the pulley 1 559 and the pulley 2 5512, the power is transmitted to the pressure wheel 5511, thereby conveying the transparent tape 50 between the pressure wheels 5511, and realizing the continuous release of the transparent tape 50 on the tape roll 502. In order to ensure reliable transmission of power when the pressure roller 2 39 detects graphite soft felt of different thicknesses, a spring rod 1 550 is provided on the swing rod 30, and the connecting frame 554 is connected to the top fixed plate 2 31 through a spring rod 2 558. When the thickness of the detected graphite soft felt changes, reliable compression between the pressure roller 2 39 and the conveyor belt 11 can be ensured, and the power of the pressure roller 2 39 can be transmitted to the clamping wheel 5511 in combination with the driving assembly 55.
