Description

Technical Field

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

[0002] A conveyor belt is a device for continuously conveying materials. Its main function is to convey 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 time of the conveyor belt surface under friction and wear conditions. A conveyor belt with good durability is not easily worn during use, can extend its service life, reduce the replacement frequency and maintenance cost. Therefore, detecting the durability of the conveyor belt can ensure the performance and reliability of the conveyor belt in actual use, so as to meet the requirements of different application scenarios.

[0003] Currently, when testing the durability of a conveyor belt, first, the conveyor belt is 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 is in tight contact with the conveyor belt. Next, the rotating roller is started to drive the conveyor belt to rotate, so that the outer side of the conveyor belt rubs against the friction roller. After rubbing for a period of time, the thickness of the conveyor belt is measured to obtain the durability of the conveyor belt.

[0004] However, when the conveyor belt is manufactured, due to manufacturing errors, the density of each part of the material on the conveyor belt cannot be the same, resulting in different durability at different positions on the conveyor belt. When the friction roller straddles the conveyor belt and rubs against it, the more wear-resistant position on the conveyor belt will顶住 the friction roller, making it impossible for the friction roller to fully rub against the less wear-resistant position on the conveyor belt. And the durability of the less wear-resistant position on the conveyor belt often determines the overall durability of the conveyor belt, so that the existing testing method cannot accurately obtain the overall durability of the conveyor belt. Moreover, when measuring the thickness of the conveyor belt in the prior art, the position where the thickness of the conveyor belt is the smallest cannot be accurately measured, resulting in an incorrect measurement result of the conveyor belt thickness, and further leading to inaccurate detection results.

[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 regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[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 upper rear side 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 arranged on the front side of the support frame 2 and slides up and down.

[0033] When it is necessary to test the durability of the conveyor belt, the conveyor belt is firstly wound on the rotating mechanism 3, and then the conveyor belt is driven to run by the detection mechanism 4. At the same time, the detection mechanism 4 rubs the conveyor belt and performs real-time detection of its elongation, thickness and weight. Within the prescribed 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 light 5, thereby ending the detection and obtaining a test result that the durability of the conveyor belt is unqualified.

[0034] See also Figure 1 and Figure 2 The rotating mechanism 3 includes a fixed ear seat 31 which is symmetrical and fixedly installed on the upper rear side of the base plate 1. A movable ear seat 32 is symmetrical and slidably arranged on the base plate 1. A rotating roller 33 is rotatably arranged on the upper part of the movable ear seat 32 and the fixed ear seat 31. A guard plate 34 corresponding to the rotating roller 33 is fixedly installed on the upper front side of the movable ear seat 32 and the upper front side of the base plate 1 by bolts. A tensioning component 35 for pushing the movable ear seat 32 is arranged at the lower part of the base plate 1.

[0035] Continue reading 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, and a push plate 352 is symmetrically and slidably arranged at the lower part of the base plate 1. The push plate 352 is threadedly connected to two threaded sections on the bidirectional threaded rod 351 respectively, and a push spring is arranged between the push plate 352 and the movable ear seat 32 at the corresponding position.

[0036] In the initial state, the guard plate 34 is not connected to the movable ear seat 32 and the base plate 1, and the two movable ear seats 32 drive the rotating rollers 33 thereon to be close to each other. The operator sets the conveyor belt to be inspected on the outside of the four rotating rollers 33 together, and then installs the guard plate 34 on the movable ear seat 32 and the base plate 1 respectively by bolts, so as to prevent the rotating rollers 33 from being skewed during rotation.

[0037] After the guard plate 34 is installed and fixed, the operator manually rotates the bidirectional threaded rod 351, so that the bidirectional threaded rod 351 drives the two push plates 352 to move away from each other, and the push plates 352 push the two movable ear seats 32 to move away from each other synchronously through the push springs, so that the two movable ear seats 32 tighten the conveyor belt through the rotating rollers 33 thereon. When the conveyor belt is tightened, the bidirectional threaded rod 351 continues to be rotated, so that the bidirectional threaded rod 351 compresses the push spring through the push plate 352, so that the elastic force of the push spring has a tendency to push the conveyor belt to extend.

[0038] See also Figure 1 , Figure 4 and Figure 6The detection mechanism 4 includes two sliding plates 41 slidably arranged on the support frame 2 up and down. The two sliding plates 41 are arranged up and down. A moving wheel frame 42 is slidably arranged on one side of the two sliding plates 41 close to each other, and a friction wheel 43 is rotatably arranged on one side of the upper and lower moving wheel frames 42 close to each other. A tightening component 47 for driving the friction wheel 43 to press against the conveyor belt is arranged on the support frame 2.

[0039] See also Figure 4 , Figure 5 and Figure 6 The clamping assembly 47 includes a T-shaped plate 471 which is slidably arranged on the rear side of the support frame 2 up and down, a synchronous plate 472 is rotatably arranged in the middle of the horizontal section of the T-shaped plate 471, and 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 sliding plate 41 at the corresponding position, and an electric push rod 474 is commonly arranged between the two sliding plates 41. An insertion rod 475 is slidably arranged on the T-shaped plate 471, and a plurality of positioning holes 476 for the insertion of the insertion rod 475 are opened at equal intervals in the up and down directions 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 move closer to each other. The sliding plate 41 drives the friction wheel 43 to press against the inner and outer side surfaces of the upper part of the conveyor belt through the movable wheel frame 42. At the same time, the reaction force of the conveyor belt on the friction wheel 43 causes the friction wheel 43 to push the two sliding plates 41 through the movable wheel frame 42 to be symmetrically arranged relative to the upper part of the conveyor belt.

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

[0042] By pushing the two sliding plates 41 back by the conveyor belt to a symmetrical arrangement, 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, the two sliding plates 41 can move synchronously in opposite directions relative to the upper part of the conveyor belt, so that the sliding plate 41 drives the friction wheels 43 on the upper and lower sides to apply the same extrusion pressure to the upper and lower sides of the conveyor belt, preventing the situation where gravity drives the upper friction wheel 43 to apply a large extrusion pressure on the upper side of the conveyor belt, while the lower friction wheel 43 applies a small extrusion pressure on the lower side of the conveyor belt.

[0043] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The detection mechanism 4 also includes a friction assembly 44 arranged on the support frame 2, and the friction assembly 44 includes an actuator motor 441 fixedly installed on the lower front side of the support frame 2. A transmission rod 442 is rotatably arranged on the side where the two sliding plates 41 are close to each other. The transmission rod 442 is slidably connected to the friction wheel 43 at the corresponding position forward and backward. Two pulleys 443 are arranged on the rear side of the support frame 2 for vertical rotation. The lower pulley 443 is fixedly connected to the output shaft of the actuator motor 441, and the lower pulley 443 is connected to the rotating roller 33 on the lower right side through a belt. A feeding part 444 that drives the friction wheel 43 to move back and forth is provided on the support frame 2, and the two transmission rods 442 are connected to the lower pulley 443 through a tensioning part 445.

[0044] See also Figure 4 , Figure 5 and Figure 6 The feeding part 444 includes reciprocating screws 4441 which are 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 two pulleys 443 and the rear ends of the two reciprocating screws 4441.

[0045] Continue reading Figure 4 , Figure 5 and Figure 6 The tensioning part 445 includes two tensioning blocks 4451 slidably arranged on the support frame 2 along the vertical direction, a tensioning spring is arranged between the tensioning block 4451 and the support frame 2, a follower rotating rod 4452 is rotatably arranged on the tensioning block 4451, and two active rotating rods 4453 are rotatably arranged on the support frame 2 and located between the two tensioning blocks 4451. Transmission gears 4454 are fixedly installed on the rear sides of the two active rotating rods 4453, and the two transmission gears 4454 are meshed with each other. The upper active rotating rod 4453 is connected to the lower pulley 443 through a belt.

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

[0047] The upper active rotating rod 4453 drives the lower active rotating rod 4453 to rotate synchronously in the opposite direction through the transmission gear 4454, and the upper active rotating rod 4453 drives the upper transmission rod 442 to rotate counterclockwise, and 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, so that the upper friction wheel 43 rubs the upper side surface of the conveyor belt. Similarly, the lower active rotating rod 4453 drives the lower friction wheel 43 to rotate clockwise, so that the lower friction wheel 43 rubs the lower side surface of the conveyor belt.

[0048] As the pulley 443 rotates, the belt wound around its outside drives the two reciprocating screws 4441 to rotate synchronously, so that the reciprocating screw 4441 drives the friction wheel 43 to move back and forth through the movable wheel frame 42, so that each position on the conveyor belt is independently rubbed by the friction wheel 43, thereby ensuring that both the wear-resistant and non-wear-resistant positions on the conveyor belt can rub against the friction wheel 43, accurately reflecting the durability of the conveyor belt, making the test result 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, and the electric push rod 474 can automatically shorten and drive the two sliding plates 41 closer to 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 tensioning spring pushes the tensioning block 4451 through its own elastic force, so that the tensioning block 4451 drives the follower rotating rod 4452 to tighten the belt between the active rotating rod 4453 and the transmission rod 442, thereby ensuring the stable rotation of the friction wheel 43.

[0050] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 The alarm light 5 is fixedly connected to the T-shaped plate 471, and a group of conductive columns 51 are fixedly installed at the left and right positions on the upper and lower sides of the alarm light 5, and each group of conductive columns 51 is composed of two conductive columns 51 symmetrically arranged front and back. The rotating mechanism 3 also includes a No. 1 trigger component 36 that is jointly arranged at the rear of the two movable ear seats 32, and the No. 1 trigger component 36 includes a movable cross bar 361 that is slid up and down and is arranged at the lower front side of the support frame 2. The left and right ends of the movable cross bar 361 are hinged to the movable ear seats 32 on both sides through hinge plates 362. A No. 1 short-circuit 363 is slid up and down on the left front part of the movable cross bar 361. The No. 1 short-circuit 363 is fixed to the movable cross bar 361 by fastening screws, and the upper part of the No. 1 short-circuit 363 is an electrode column structure that is mutually conductive.

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

[0052] When the elongation exceeds the standard, the movable cross bar 361 drives the No. 1 short-circuit component 363 to move upward to connect with a group of conductive columns 51 on the lower left side of the alarm light 5, so that the group of conductive columns 51 on the lower left side of the alarm light 5 are connected to each other, thereby lighting up the alarm light 5, and then concluding that the durability of the conveyor belt is unqualified.

[0053] It should be noted that by moving the height of the No. 1 short-circuit component 363 on the movable cross bar 361 up and down in advance, the alarm light 5 can be turned on when the conveyor belt is extended by different amounts, thereby being able to adapt to different detection requirements.

[0054] See also Figure 1 , Figure 4 , Figure 7 and Figure 8 The detection mechanism 4 also includes a No. 2 trigger assembly 45 arranged on the support frame 2, and the No. 2 trigger assembly 45 includes a suction bin 451 which is slidably arranged on the right side of the support frame 2, and a constant force spring is arranged between the lower part of the suction bin 451 and the support frame 2, and a driven cross bar 453 is fixedly installed on the upper part of the suction bin 451, and a No. 2 short-circuit 454 is slidably arranged on the left side of the driven cross bar 453, and the No. 2 short-circuit 454 is fixed to the driven cross bar 453 by fastening screws, and an air guide pipe 455 is fixedly installed on the right side of the mobile wheel frame 42, and the lower end of the air guide pipe 455 is aligned with the friction wheel 43 at the corresponding position, and a shovel plate 456 for shoveling away rubber particles adhered to the friction wheel 43 is fixedly installed on the lower part of the air guide pipe 455, and the ends of the two air guide pipes 455 that are away from each other are connected to the suction bin 451 through a pipe 457, and the lower part of the No. 2 short-circuit 454 is an electrode column structure that is mutually conductive.

[0055] When the friction wheel 43 starts to rotate, the friction wheel 43 rubs the conveyor belt, so that the rubber particles on the conveyor belt are ground off, and at the same time, negative pressure is generated through the suction bin 451, so that the suction bin 451 absorbs the fallen rubber particles through the pipeline 457 and the air guide pipe 455. In addition, the rubber particles that melt and adhere to the friction wheel 43 due to the high temperature of friction are shoveled off by the shovel plate 456 and then absorbed by the air guide pipe 455, so that the rubber particles that fall off the conveyor belt are introduced into the interior of the suction bin 451.

[0056] When the rubber particles inside the suction bin 451 increase, it indicates that more rubber particles have fallen on the conveyor belt, which indicates that the overall mass of the conveyor belt has decreased. At the same time, the weight of the suction bin 451 increases and compresses the constant force spring downward, and the suction bin 451 drives the No. 2 short-circuit 454 to move downward synchronously through the driven cross bar 453. When the rubber particles falling on the conveyor belt exceed the detection standard, the overall mass of the surface conveyor belt is less than the standard, that is, the conveyor belt is excessively worn as a whole. At this time, the No. 2 short-circuit 454 moves downward until it is connected to a group of conductive columns 51 on the upper left side of the alarm light 5, thereby lighting up the alarm light 5, and then concluding that the durability of the conveyor belt is unqualified.

[0057] It should be noted that by moving the height of the second short-circuit component 454 on the driven cross bar 453 up and down in advance, the alarm light 5 can be turned on when the conveyor belt has different qualities, thereby being able to adapt to different detection requirements.

[0058] See also Figure 1 , Figure 4 , Figure 7 and Fig. 9 The detection mechanism 4 also includes a No. 3 trigger component 46 arranged on the moving wheel frame 42, and the No. 3 trigger component 46 includes a pressing column 461 which is slidably arranged on the left side of the moving wheel frame 42, and a ball 462 is rolled on the lower side of the pressing column 461. A tension spring is arranged between the pressing column 461 and the moving wheel frame 42, and a driven plate 463 is slidably arranged on the support frame 2 along the vertical direction. The driven plate 463 is connected to the pressing column 461 at the corresponding position for front and rear sliding. A No. 3 short-circuit 464 is slidably arranged on the left rear part of the driven plate 463, and the No. 3 short-circuit 464 is fixed to the driven plate 463 by screws. The No. 3 short-circuit 464 is close to the side of the alarm light 5 and has an electrode column structure that is mutually conductive.

[0059] When the moving wheel frame 42 moves back and forth, the moving wheel frame 42 synchronously drives the pressing column 461 to move, so that the pressing column 461 drives the ball 462 to always press on the position of the conveyor belt that is polished by the friction wheel 43 under the elastic force of the tension spring. When the friction wheel 43 reduces the thickness of the conveyor belt polished, the elastic force of the tension spring drives the pressing column 461 to move toward the conveyor belt. At the same time, the pressing column 461 drives the No. 3 short-circuit 464 to move toward the direction close to the alarm light 5 through the driven plate 463.

[0060] When the thickness of the conveyor belt is too thin, the No. 3 short-circuit 464 moves to be connected to the corresponding group of conductive columns 51 on the right side of the alarm light 5, so that the alarm light 5 lights up, and then it is concluded that the durability of the conveyor belt is unqualified. The operator can adjust the position of the No. 3 short-circuit 464 up and down by turning the screw in advance, so that the alarm light 5 can be lit when the local thickness of the conveyor belt is different, thereby adapting to different detection needs.

[0061] When testing the durability of the conveyor belt, the present invention also includes the following steps: In the first step, the operator puts the conveyor belt to be tested together on the outside of the four rotating rollers 33, and then installs the guard plate 34 on the movable ear seat 32 and the base plate 1 respectively by bolts, so as to prevent the rotating roller 33 from being skewed during rotation.

[0062] In the second step, the operator manually rotates the bidirectional threaded rod 351 to control the two movable ear seats 32 to move away from each other synchronously, so that the two movable ear seats 32 tighten the conveyor belt through the rotating rollers 33 thereon. When the conveyor belt is tightened, the bidirectional threaded rod 351 continues to be rotated, so that the bidirectional threaded rod 351 compresses the push spring through the push plate 352.

[0063] In the third step, the operator retracts the telescopic section of the electric push rod 474 to drive the two friction wheels 43 to press 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, thereby fixing 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] The fourth step is to start the execution motor 441 to drive the friction wheel 43 to rub the upper and lower sides of the conveyor belt. At the same time, the two reciprocating screws 4441 drive the friction wheel 43 to move back and forth, so that the friction wheel 43 independently rubs each position on the conveyor belt.

[0065] The fifth step, when the elongation exceeds the standard, the moving cross bar 361 drives the No. 1 short-circuit 363 to move upward to connect with a group of conductive posts 51 on the lower left side of the alarm light 5, so that the group of conductive posts 51 on the lower left side of the alarm light 5 are connected to each other, thereby lighting up the alarm light 5, and then concluding that the durability of the conveyor belt is unqualified.

[0066] The sixth step is that when the rubber particles dropped from the conveyor belt exceed the inspection standard, the overall mass of the surface conveyor belt is less than the standard, that is, the conveyor belt as a whole is excessively worn. At this time, the No. 2 short-circuit 454 moves downward to conduct with a group of conductive columns 51 on the upper left side of the alarm light 5, thereby lighting up the alarm light 5, and then concluding that the durability of the conveyor belt is unqualified.

[0067] In the seventh step, when the thickness of the conveyor belt is too thin, the No. 3 short-circuit component 464 moves to be connected with the corresponding group of conductive posts 51 on the right side of the alarm light 5, so that the alarm light 5 lights up, thereby concluding that the durability of the conveyor belt is unqualified.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
