Abstract

The present invention relates to the field of detection devices, specifically a conveyor belt performance detection device, which includes a base plate. A support frame is fixedly installed on the upper rear side of the base plate. The upper part of the support frame is in a U-shaped structure. A rotating mechanism for rotating the conveyor belt is arranged on the upper part of the base plate. A detection mechanism for detecting the durability of the conveyor belt is arranged on the support frame. An alarm lamp is slidably arranged up and down on the front side of the support frame. The present invention adopts a tightening component to drive two friction wheels to always tightly press against the inner and outer sides of the conveyor belt.

Description

Technical Field

[0001] The invention relates to the field of detection devices, in particular to a conveyor belt performance detection device. Background Art

[0002] A conveyor belt is a device used to continuously transport materials. Its main function is to transport materials from one location to another, thereby improving production efficiency and reducing labor intensity. The durability of a conveyor belt refers to the maximum service life of the conveyor belt surface under friction and wear conditions. A conveyor belt with good durability is not easily worn during use, which can extend its service life and reduce replacement frequency and maintenance costs. Therefore, testing the durability of the conveyor belt can ensure the performance and reliability of the conveyor belt in actual use, thereby meeting the needs of different application scenarios.

[0003] Currently, when testing the durability of a conveyor belt, the conveyor belt is first installed and wound around a rotating roller. Then a friction roller is placed on the outer side of the conveyor belt so that the friction roller and the conveyor belt are in close contact. The rotating roller is then started to drive the conveyor belt to rotate so that the outer side of the conveyor belt rubs against the friction roller. After a period of friction, the thickness of the conveyor belt is measured to determine the durability of the conveyor belt.

[0004] However, when the conveyor belt is manufactured, the density of the material at every location on the conveyor belt cannot be the same due to manufacturing errors, resulting in different durability at different locations on the conveyor belt. When the friction roller spans the conveyor belt and rubs against it, the more wear-resistant location on the conveyor belt will press against the friction roller, making it impossible for the friction roller to fully rub against the less wear-resistant location on the conveyor belt. The durability of the less wear-resistant location on the conveyor belt often determines the overall durability of the conveyor belt, so that the existing testing method cannot accurately determine the overall durability of the conveyor belt. In addition, when measuring the thickness of the conveyor belt, the existing technology cannot accurately measure the location where the thickness of the conveyor belt is the smallest, which makes the measurement result of the conveyor belt thickness incorrect, and further leads to inaccurate detection results.

[0014] As a preferred technical solution of the present invention, the first triggering component includes a moving cross bar slidably arranged up and down at the lower part of the front side of the support frame. The left and right ends of the moving cross bar are respectively hinged to the moving ear seats on both sides through hinge plates. A first short connecting piece is slidably arranged up and down on the left side of the front part of the moving cross bar.

[0015] As a preferred technical solution of the present invention, the second triggering component includes a suction bin slidably arranged up and down on the right side of the support frame. A constant force spring is arranged between the lower part of the suction bin and the support frame. A driven cross bar is fixedly installed on the upper part of the suction bin. A second short connecting piece is slidably arranged up and down on the left side of the driven cross bar. The second short connecting piece is fixed to the driven cross bar through a fastening screw. A duct component is fixedly installed on the right side of the moving wheel frame.

[0017] The beneficial effects of the present invention are as follows: First, the present invention adopts a pressing component to drive the two friction wheels to always press against the inner and outer sides of the conveyor belt. At the same time, the friction component can drive the friction wheels to reciprocate in the front and rear directions, so that the friction wheels perform independent friction tests on various positions on the inner and outer sides of the conveyor belt, ensuring that both the wear-resistant and non-wear-resistant positions on the conveyor belt can be in friction with the friction wheels, thereby accurately reflecting the durability of the conveyor belt and making the test results more accurate.

[0018] II. The present invention uses a second trigger component to measure the thickness of the position on the conveyor belt that has been polished by the friction wheel in real time. Once it is measured that the thickness of the conveyor belt is less than the specified thickness, a detection failure result can be obtained. By means of real-time measurement following the friction wheel, the thickness of the least wear-resistant position on the conveyor belt can be accurately captured, thereby further increasing the accuracy of the detection result.

[0019] III. The present invention uses a first trigger component to detect the elongation of the conveyor belt. When the conveyor belt is worn excessively and causes excessive elongation, the first trigger component can detect that the durability of the conveyor belt is unqualified. At the same time, a third trigger component is used to collect and weigh the rubber particles polished from the conveyor belt in real time. When there are too many rubber particles polished from the conveyor belt, the third trigger component can detect that the durability of the conveyor belt is unqualified. By simultaneously detecting the elongation, thickness, and weight of the conveyor belt through the first trigger component, the second trigger component, and the third trigger component, the accuracy of the detection is further increased.

Specific embodiments

[0031] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments, the techniques or conditions described in the literature in this field or according to the product manual are followed.

[0032] Refer to Figure 1 、 Figure 2 and Figure 4 , a conveyor belt performance detection device, including a base plate 1, a support frame 2 is fixedly installed on the rear side of the upper part of the base plate 1, the upper part of the support frame 2 is in a U-shaped structure, a rotating mechanism 3 for rotating the conveyor belt is arranged on the upper part of the base plate 1, a detection mechanism 4 for detecting the durability of the conveyor belt is arranged on the support frame 2, and an alarm lamp 5 is slidably arranged up and down on the front side of the support frame 2.

[0033] When it is necessary to detect the durability of the conveyor belt, first wind the conveyor belt around the rotating mechanism 3, and then drive the conveyor belt to run through the detection mechanism 4. At the same time, the detection mechanism 4 frictions the conveyor belt and detects its elongation, thickness, and weight in real time. Within the specified detection time, when one of the elongation, thickness, and weight of the conveyor belt does not meet the standard, the detection mechanism 4 can light up the alarm lamp 5, thereby ending the detection and obtaining the detection result that the durability of the conveyor belt is unqualified.

[0034] Refer to Figure 1 and Figure 2 , the rotating mechanism 3 includes fixed ear seats 31 that are symmetrically arranged left and right and fixedly installed on the rear side of the upper part of the base plate 1. Moving ear seats 32 are symmetrically arranged left and right and slidably arranged on the base plate 1. Rotating rollers 33 are rotatably arranged on the upper parts of the moving ear seats 32 and the fixed ear seats 31. Protective plates 34 corresponding to the rotating rollers 33 are fixedly installed on the front side of the upper part of the moving ear seats 32 and the front side of the upper part of the base plate 1 through bolts. A tensioning assembly 35 for pushing the moving ear seats 32 is arranged at the lower part of the base plate 1.

[0035] Continue to refer to Figure 1 and Figure 2 , the tensioning assembly 35 includes a bidirectional threaded rod 351 rotatably arranged at the lower part of the base plate 1. Pushing plates 352 are symmetrically arranged left and right and slidably arranged left and right at the lower part of the base plate 1. The pushing plates 352 are respectively threadedly connected to two threaded sections on the bidirectional threaded rod 351. A pushing spring is arranged between the pushing plates 352 and the corresponding moving ear seats 32.

[0036] In the initial state, the protective plates 34 are not connected to the moving ear seats 32 and the base plate 1, and the two moving ear seats 32 drive the rotating rollers 33 on them to be in a position close to each other. The operator sleeved the conveyor belt to be detected on the outside of the four rotating rollers 33 together, and then installed the protective plates 34 on the moving ear seats 32 and the base plate 1 respectively through bolts, thereby preventing the rotating rollers 33 from skewing during rotation.

[0037] After the protective plates 34 are installed and fixed, the operator manually rotates the bidirectional threaded rod 351, so that the bidirectional threaded rod 351 drives the two pushing plates 352 to move away from each other. The pushing plates 352 push the two moving ear seats 32 to move away from each other synchronously through the pushing springs, so that the two moving ear seats 32 tighten the conveyor belt through the rotating rollers 33 on them. When the conveyor belt is tightened, continue to rotate the bidirectional threaded rod 351, so that the bidirectional threaded rod 351 compresses the pushing spring through the pushing plates 352, so that the elastic force of the pushing spring has a tendency to push the conveyor belt to elongate.

[0038] Refer to Figure 1 , Figure 4 and Figure 6, the detection mechanism 4 includes two sliding plates 41 that are slidably arranged up and down on the support frame 2. The two sliding plates 41 are arranged vertically. A moving wheel frame 42 is slidably arranged back and forth on the sides of the two sliding plates 41 that are close to each other. Friction wheels 43 are rotatably arranged on the sides of the upper and lower moving wheel frames 42 that are close to each other. A pressing component 47 for driving the friction wheels 43 to press against the conveyor belt is arranged on the support frame 2.

[0039] Refer to Figure 4 , Figure 5 and Figure 6 , the pressing component 47 includes a T-shaped plate 471 that is slidably arranged up and down on the rear side of the support frame 2. A synchronous plate 472 is rotatably arranged in the middle of the horizontal section of the T-shaped plate 471. Connecting plates 473 are hinged at both ends of the synchronous plate 472. The end of the connecting plate 473 away from the synchronous plate 472 is hinged to the corresponding sliding plate 41. An electric push rod 474 is jointly arranged between the two sliding plates 41. An insertion rod 475 is slidably arranged back and forth on the T-shaped plate 471. A number of positioning holes 476 for the insertion rod 475 to penetrate are equally spaced in the vertical direction on the support frame 2.

[0040] When the conveyor belt is tightened on the rotating roller 33, the upper part of the conveyor belt is located between the two sliding plates 41. Then, the operator contracts the telescopic section of the electric push rod 474, so that the electric push rod 474 drives the two sliding plates 41 to approach each other. The sliding plates 41 drive the friction wheels 43 to abut against the inner and outer sides of the upper part of the conveyor belt through the moving wheel frame 42. At the same time, due to the reaction force of the conveyor belt on the friction wheels 43, the friction wheels 43 push the two sliding plates 41 to be symmetrically arranged relative to the upper part of the conveyor belt through the moving wheel frame 42.

[0041] When one side of the sliding plate 41 moves, it drives the synchronous plate 472 to rotate through the corresponding connecting plate 473. The synchronous plate 472 drives the sliding plate 41 on the other side to move synchronously and in the opposite direction through the connecting plate 473 on the other side, so that the middle of the synchronous plate 472 is always located at the central position between the two sliding plates 41. Thus, the synchronous plate 472 drives the T-shaped plate 471 to slide vertically to the central position above the conveyor belt. Subsequently, the operator holds the insertion rod 475 and inserts it into the corresponding positioning hole 476, thereby fixedly connecting the T-shaped plate 471 and the support frame 2 together.

[0042] By pushing the two sliding plates 41 to be symmetrically arranged by the conveyor belt, it can automatically adapt to conveyor belts of different thicknesses for detection. When the T-shaped plate 471 is fixedly connected to the support frame 2, it can make the two sliding plates 41 move synchronously and in the opposite direction relative to the upper part of the conveyor belt, so that the sliding plates 41 drive the upper and lower friction wheels 43 to apply the same extrusion force to the upper and lower sides of the conveyor belt, preventing the situation where the extrusion force of the upper friction wheel 43 on the upper side of the conveyor belt is large due to gravity and the extrusion force of the lower friction wheel 43 on the lower side of the conveyor belt is small.

[0043] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in FIGS.

[0044] Refer to Figure 4 、 Figure 5 and Figure 6 The feeding part 444 includes reciprocating screws 4441 respectively rotatably arranged on the sides of the two sliding plates 41 away from each other. The reciprocating screws 4441 are threadedly connected to the moving wheel frames 42 at corresponding positions. A belt is wound around the rear ends of the two belt pulleys 443 and the two reciprocating screws 4441 together.

[0045] Continue to refer to Figure 4 、 Figure 5 and Figure 6 The tensioning part 445 includes two tensioning blocks 4451 slidably arranged on the support frame 2 in the vertical direction. A tensioning spring is arranged between the tensioning blocks 4451 and the support frame 2. A follower rotating rod 4452 is rotatably arranged on the tensioning blocks 4451. Two driving rotating rods 4453 are rotatably arranged on the support frame 2 and between the two tensioning blocks 4451. Transmission gears 4454 are fixedly installed on the rear sides of the two driving rotating rods 4453. The two transmission gears 4454 mesh with each other. The upper driving rotating rod 4453 is connected to the lower belt pulley 443 by a belt.

[0046] After the T-shaped plate 471 is fixedly connected to the support frame 2, the actuating motor 441 is started to drive the lower belt pulley 443 to rotate. The lower belt pulley 443 drives the upper belt pulley 443 to rotate synchronously. At the same time, the lower belt pulley 443 also drives the upper driving rotating rod 4453 and the lower right rotating roller 33 to rotate synchronously. The lower right rotating roller 33 drives the conveyor belt to rotate counterclockwise, that is, the upper part of the conveyor belt moves from right to left.

[0047] ​​​The upper driving rotating rod 4453 drives the lower driving rotating rod 4453 to rotate synchronously and in the opposite direction through the transmission gear 4454. The upper driving rotating rod 4453 drives the upper transmission rod 442 to rotate counterclockwise. The upper transmission rod 442 drives the upper friction wheel 43 to rotate counterclockwise synchronously, that is, the lower part of the upper friction wheel 43 rotates from left to right, thereby enabling the upper friction wheel 43 to friction the upper surface of the conveyor belt. Similarly, the lower driving rotating rod 4453 drives the lower friction wheel 43 to rotate clockwise, enabling the lower friction wheel 43 to friction the lower surface of the conveyor belt.

[0048] While the pulley 443 rotates, it drives two reciprocating screws 4441 to rotate synchronously through the belt wound around its outer side, enabling the reciprocating screws 4441 to drive the friction wheel 43 to move back and forth through the moving wheel frame 42, so as to independently friction each position on the conveyor belt through the friction wheel 43, thereby ensuring that both the wear-resistant and non-wear-resistant positions on the conveyor belt can friction with the friction wheel 43, accurately reflecting the durability of the conveyor belt and making the test results more accurate.

[0049] It should be noted that when the friction wheel 43 wears the conveyor belt, the thickness of the conveyor belt becomes smaller. The electric push rod 474 can automatically shorten to drive the two sliding plates 41 to approach each other, thereby ensuring that the pressing force of the friction wheel 43 on the conveyor belt is always the same. And when the friction wheel 43 moves, the tension spring pushes the tension block 4451 through its own elastic force, enabling the tension block 4451 to drive the follower rotating rod 4452 to tighten the belt between the driving rotating rod 4453 and the transmission rod 442, thereby ensuring the stable rotation of the friction wheel 43.

[0050] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown in

[0051] When the conveyor belt elongates due to wear, the pushing spring uses its own elastic force to push the moving ear seats 32 on both sides away from each other. When one moving ear seat 32 moves away from the support frame 2, the moving ear seat 32 can pull the moving cross bar 361 upward through the hinge plate 362 at the corresponding position. When the moving cross bar 361 moves upward, it can push the moving ear seat 32 on the other side to move away from the support frame 2 synchronously through the hinge plate 362 on the other side, so that the two moving ear seats 32 move synchronously in opposite directions.

[0052] When the elongation exceeds the standard, the moving cross bar 361 drives the first short connector 363 to move upward until it is connected to a set of conductive columns 51 on the lower left side of the alarm lamp 5, making a set of conductive columns 51 on the lower left side of the alarm lamp 5 conduct with each other, so that the alarm lamp 5 lights up, and then it is concluded that the durability of the conveyor belt is unqualified.

[0053] It should be noted that by pre-adjusting the height of the first short connector 363 on the moving cross bar 361 up and down, the alarm lamp 5 can be lit when the conveyor belt elongates by different amounts, and thus different detection requirements can be met.

[0054] Refer to Figure 1 、 Figure 4 、 Figure 7 and Figure 8 As shown in FIGS., the detection mechanism 4 further includes a second trigger assembly 45 provided on the support frame 2. The second trigger assembly 45 includes a suction chamber 451 slidably arranged up and down on the right side of the support frame 2. A constant force spring is arranged between the lower part of the suction chamber 451 and the support frame 2. A driven cross bar 453 is fixedly installed on the upper part of the suction chamber 451. A second short connector 454 is slidably arranged up and down on the left side of the driven cross bar 453. The second short connector 454 is fixed to the driven cross bar 453 by fastening screws. A gas guide member 455 is fixedly installed on the right side of the moving wheel frame 42. The lower end of the gas guide member 455 is aligned with the friction wheel 43 at the corresponding position. A scraper plate 456 for removing the rubber particles adhered to the friction wheel 43 is fixedly installed on the lower part of the gas guide member 455. The mutually remote ends of the two gas guide members 455 are communicated with the suction chamber 451 through a pipeline 457. The lower part of the second short connector 454 is in the structure of electrode columns that conduct with each other.

[0055] When the friction wheel 43 starts to rotate, the friction wheel 43 frictions the conveyor belt, so that the rubber particles on the conveyor belt are polished and fall off. At the same time, a negative pressure is generated in the suction chamber 451, so that the suction chamber 451 and the gas guide member 455 suck the fallen rubber particles through the pipeline 457. In addition, the rubber particles melted and adhered to the friction wheel 43 due to frictional heat are scraped off by the scraper plate 456 and then sucked by the gas guide member 455, so that the rubber particles falling off the conveyor belt are introduced into the interior of the suction chamber 451.

[0056] When the rubber particles inside the suction bin 451 increase, it indicates that there are more rubber particles falling on the conveyor belt, thus indicating that the overall quality of the conveyor belt decreases. At the same time, the suction bin 451 gains weight and compresses the constant force spring downward, and the suction bin 451 drives the second short connector 454 to move downward synchronously through the driven cross bar 453. When the rubber particles falling on the conveyor belt exceed the detection standard, it means that the overall quality of the conveyor belt is less than the standard, that is, the overall wear of the conveyor belt is excessive. At this time, the second short connector 454 moves downward to be electrically connected to a set of conductive columns 51 on the upper left side of the alarm lamp 5, so that the alarm lamp 5 is lit, and then it is concluded that the durability of the conveyor belt is unqualified.

[0057] It should be noted that by pre-adjusting the height of the second short connector 454 on the driven cross bar 453, the alarm lamp 5 can be lit when the conveyor belt has different qualities, and thus different detection requirements can be met.

[0058] Refer to Figure 1 、 Figure 4 、 Figure 7 and Figure 9 As shown in FIGS.

[0059] When the mobile wheel frame 42 reciprocates back and forth, the mobile wheel frame 42 drives the pressing column 461 to move synchronously, so that the pressing column 461 drives the running bead 462 to always press on the position of the conveyor belt polished by the friction wheel 43 under the elastic force of the tension spring. When the thickness of the conveyor belt polished by the friction wheel 43 decreases, the elastic force of the tension spring drives the pressing column 461 to move towards the conveyor belt, and at the same time, the pressing column 461 drives the third short connector 464 to move towards the alarm lamp 5 through the driven plate 463.

[0060] When the thickness of the conveyor belt is too thin, the third short connector 464 moves to be electrically connected to the corresponding set of conductive columns 51 on the right side of the alarm lamp 5, so that the alarm lamp 5 is lit, and then it is concluded that the durability of the conveyor belt is unqualified. And the operator can adjust the position of the third short connector 464 up and down by pre-rotating the screw, so that the alarm lamp 5 can be lit when the local part of the conveyor belt has different thicknesses, and thus different detection requirements can be met.

[0061] When detecting the durability of the conveyor belt, the present invention further includes the following steps: First step, the operator sleeved the conveyor belt to be detected on the outer sides of the four rotating rollers 33 together, and then installed the guard plates 34 on the moving ear seats 32 and the base plate 1 through bolts respectively, so as to prevent the rotating rollers 33 from skewing during rotation.

[0062] Second step, the operator manually rotates the bidirectional threaded rod 351 to control the two moving ear seats 32 to move away from each other synchronously, so that the two moving ear seats 32 tighten the conveyor belt through the rotating rollers 33 on them. When the conveyor belt is tightened, continue to rotate the bidirectional threaded rod 351, so that the bidirectional threaded rod 351 compresses the pushing spring through the pushing plate 352.

[0063] Third step, the operator contracts the telescopic section of the electric push rod 474 to drive the two friction wheels 43 to abut against the inner and outer sides of the upper part of the conveyor belt. Then the operator holds the insertion rod 475 and inserts it into the positioning hole 476 at the corresponding position, so as to fixedly connect the T-shaped plate 471 and the support frame 2 together, so that the friction wheels 43 apply the same extrusion force to the upper and lower sides of the conveyor belt.

[0064] Fourth step, start the execution motor 441 to drive the friction wheels 43 to rub the upper and lower sides of the conveyor belt. At the same time, the two reciprocating threaded rods 4441 drive the friction wheels 43 to move back and forth, so that the friction wheels 43 rub each position on the conveyor belt independently.

[0065] Fifth step, when the elongation exceeds the standard, the moving cross bar 361 drives the first short connector 363 to move upward to connect with a group of conductive columns 51 on the lower left side of the alarm lamp 5, so that a group of conductive columns 51 on the lower left side of the alarm lamp 5 are electrically connected to each other, so that the alarm lamp 5 lights up, and then it is concluded that the durability of the conveyor belt is unqualified.

[0066] Sixth step, when the rubber particles falling on the conveyor belt exceed the detection standard, it means that the overall quality of the surface conveyor belt is less than the standard, that is, the overall conveyor belt is excessively worn. At this time, the second short connector 454 moves downward to be electrically connected to a group of conductive columns 51 on the upper left side of the alarm lamp 5, so that the alarm lamp 5 lights up, and then it is concluded that the durability of the conveyor belt is unqualified.

[0067] Seventh step, when the thickness of the conveyor belt is too thin, the third short connector 464 moves to be electrically connected to the corresponding group of conductive columns 51 on the right side of the alarm lamp 5, so that the alarm lamp 5 lights up, and then it is concluded that the durability of the conveyor belt is unqualified.

[0068] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
