Description

Technical Field

[0001] The present invention relates to the technical field of material detection, and particularly to a detection device for manufacturing rubber conveyor belts. Background Art

[0002] A rubber conveyor belt is a drive belt used to convey various materials. It is usually composed of a rubber layer and a skeleton material. The rubber layer wraps around the upper and lower surfaces of the conveyor belt, directly contacting the materials and the external environment, playing a role in protecting the skeleton material and conveying the materials. It usually has properties such as wear resistance, oil resistance, acid and alkali resistance, and aging resistance. The skeleton material is the load-bearing part of the conveyor belt, providing strength and flexibility to the conveyor belt so that it can withstand the weight of the materials and the tensile force during the conveying process.

[0003] In order to ensure the quality of rubber conveyor belts, performance detection of the rubber layer is required during its manufacturing process. Traditional detection devices usually consist of two rotating rollers. The distance between the two rotating rollers can be adjusted and they can rotate in the same direction. After sleeving the rubber belt on the two rotating rollers, the tensile performance of the rubber belt is detected by adjusting the distance between the rotating rollers, and the wear resistance of the rubber belt is detected by driving the rubber belt to rotate through the rotating rollers.

[0004] During the manufacturing process of the conveyor belt, the rubber belt is first in a strip-shaped wound state, and then after shearing, the head and tail of the rubber belt are connected to form an annular state. Existing detection devices can only detect the performance of the rubber belt in a single state, easily missing defects that only appear in other states. For example, when the rubber belt is in a strip-shaped wound state, fine cracks inside will become obvious due to bending during annular detection, and the bonding problem at the joint can only be detected when the rubber belt is in an annular state. Therefore, it is necessary to design a device that can detect the performance of the rubber belt in different states. Summary of the Invention

[0012] As a further description of a detection device for manufacturing a rubber conveyor belt of the above technology: A rotating shaft is fixedly connected to one side of the mounting seat. The friction roller is rotatably connected to the rotating shaft.

[0013] As a further description of a detection device for manufacturing a rubber conveyor belt of the above technology: There are two friction rollers, mounting seats and threaded rods, and they are symmetrically arranged with respect to the intersection of the two threads of the bidirectional lead screw.

[0014] Further description of a detection device for manufacturing a rubber conveyor belt as the above-mentioned technology: A connection accessory is arranged inside the friction roller.

At the same time, the friction roller is attached to the rubber belt. During the detection process, the offset of the rubber belt will drive the friction roller to deflect.

Detailed implementation mode

[0019] The following will clearly and completely describe a rubber conveyor belt manufacturing detection device in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0020] As Figures 1-11 shown, a rubber conveyor belt manufacturing detection device provided by the present invention includes a housing 10. A motor 11 and an electric telescopic rod 14 are fixedly installed inside the housing 10. A slider 12 fixedly connected to the telescopic end of the electric telescopic rod 14 is slidably connected inside the housing 10. The telescopic movement of the electric telescopic rod 14 drives the slider 12 to move up and down inside the housing 10. Two movable support rollers 13 are rotatably connected to one side of the slider 12. The slider 12 drives the movable support rollers 13 to move up and down to adjust the position of the movable support rollers 13. It further includes: A driving mechanism 20. The driving mechanism 20 includes two fixed support rollers 21 rotatably connected to one side of the housing 10 and vertically aligned with the two movable support rollers 13 respectively. The vertical movement of the movable support rollers 13 will change the distance between them and the fixed support rollers 21. When detecting a strip-shaped rubber belt, by adjusting the distance between the movable support rollers 13 and the fixed support rollers 21, the movable support rollers 13 and the fixed support rollers 21 can clamp and convey rubber belts of different thicknesses. One end of each of the fixed support rollers 21 and the movable support rollers 13 is fixedly connected with a worm gear 22. The driving shaft of the motor 11 is fixedly connected with a fixed worm 23. A connection unit 25 and a control unit 26 are arranged above the fixed worm 23. A transmission assembly 24 is arranged on one side of the slider 12; When the distance between the movable support rollers 13 and the fixed support rollers 21 is adjusted by the telescopic movement of the electric telescopic rod 14, and the movable support rollers 13 and the fixed support rollers 21 apply pressure to both sides of the rubber belt respectively, the detection of the strip-shaped rubber belt is realized. When the movable support rollers 13 and the fixed support rollers 21 apply tension to the inner wall of the rubber belt, the detection of the annular rubber belt is realized.

[0021] Refer to Figure 4 and Figure 5, in order to enable the movable supporting roller 13 to still rotate under the drive of the motor 11 after the position adjustment, the transmission assembly 24 includes a square rod 241 fixed to the top end of the connecting rod 252. One side of the slider 12 is rotatably connected with a movable worm 242 slidably connected with the square rod 241. When the slider 12 and the movable supporting roller 13 are adjusted in position, the movable worm 242 is driven to slide on the square rod 241. When the motor 11 drives the fixed worm 23 to rotate, the square rod 241 can be driven to rotate through the connecting unit 25 to make the movable worm 242 rotate. The movable worm 242 and the fixed worm 23 are respectively meshed and connected with two worm wheels 22. Therefore, through the transmission of the worm wheels 22, the movable supporting roller 13 and the fixed supporting roller 21 can be driven to rotate respectively. The thread directions of the fixed worm 23 and the movable worm 242 are opposite, so that the rotating directions of the fixed supporting roller 21 and the movable supporting roller 13 are opposite.

[0022] In order to be able to control the rotation of the fixed supporting roller 21 alone while the movable supporting roller 13 does not rotate, so that the annular rubber belt can circulate and rotate outside the movable supporting roller 13 and the fixed supporting roller 21 to simulate the actual working condition, the connecting unit 25 includes a fixed seat 251 fixed to the top end of the fixed worm 23. The inside of the fixed seat 251 is rotatably connected with a connecting rod 252. The inside of the fixed seat 251 is slidably connected with a first insert block 254 embedded at the bottom end of the connecting rod 252. A spring 253 is arranged between the first insert block 254 and the fixed seat 251. The spring 253 is always in a compressed state. The first insert block 254 is embedded in the connecting rod 252 under the elastic force of the spring 253, so that when the fixed seat 251 rotates, the connecting rod 252 and the square rod 241 are driven to rotate through the first insert block 254. The control unit 26 includes a magnet 261 fixed inside the first insert block 254. An electromagnet 262 is fixedly installed inside the fixed seat 251. After controlling the electromagnet 262 to generate magnetic suction to drive the first insert block 254 to disengage from the connecting rod 252, the rotation of the fixed seat 251 no longer drives the connecting rod 252 and the square rod 241 to rotate, so that the movable supporting roller 13 stops rotating.

[0023] Refer to Figure 3 and Figure 6 , it further includes a grinding mechanism 30. The grinding mechanism 30 includes a movable frame 31 slidably connected inside the housing 10. The top of the housing 10 is threadedly connected with a threaded rod 32 rotatably connected with the movable frame 31. A spacing adjustment assembly 34 is arranged inside the movable frame 31. A friction roller 33 is arranged on one side of the housing 10. By rotating the threaded rod 32, the movable frame 31 can be driven to lift inside the housing 10, and the position of the friction roller 33 can be adjusted according to the positions of the movable supporting roller 13 and the fixed supporting roller 21, so that the friction roller 33 can contact the annular rubber belt supported by the passive supporting roller 13 and the fixed supporting roller 21.

[0024] Refer to Figure 6 and Figure 7, in order to enable the two friction rollers 33 to move synchronously and support on both sides of the inner wall or the outer wall of the annular rubber belt with the same pressure, the spacing adjustment assembly 34 includes a mounting seat 341 slidably connected to the inside of the movable frame 31. One side of the mounting seat 341 is fixedly connected with a threaded cylinder 342. One side of the movable frame 31 is rotatably connected with a bidirectional lead screw 343 threadedly connected to the threaded cylinder 342. One side of the mounting seat 341 is fixedly connected with a rotating shaft 35. The friction roller 33 is rotatably connected to the rotating shaft 35. There are two friction rollers 33, mounting seats 341 and threaded rods 32, and they are symmetrically arranged with the two-thread intersection of the bidirectional lead screw 343 as the axis of symmetry. Therefore, when the bidirectional lead screw 343 rotates, it drives the two threaded cylinders 342, mounting seats 341 and friction rollers 33 to move towards each other or away from each other.

[0025] Refer to Figure 7 and Figure 8 , a connection accessory 36 is arranged inside the friction roller 33. The connection accessory 36 includes a motor 361 fixedly installed inside the mounting seat 341. A connecting piece 365 fixedly connected to the driving shaft of the motor 361 is rotatably connected inside the mounting seat 341. A fixed shaft 362 is fixedly connected inside the friction roller 33. A threaded rotating rod 363 is rotatably connected inside the fixed shaft 362. One end of the threaded rotating rod 363 is threadedly connected with a second insert block 364 slidably connected inside the fixed shaft 362. When the second insert block 364 is inserted into the connecting piece 365, the driving shaft of the motor 361 rotates and drives the fixed shaft 362 and the friction roller 33 to rotate through the connecting piece 365 and the second insert block 364. When the friction roller 33 contacts the rubber belt, the rotation of the friction roller 33 can detect the wear resistance of the rubber belt. When the second insert block 364 is not inserted into the connecting piece 365, since the friction roller 33 is rotatably connected to the rotating shaft 35, at this time, when the friction roller 33 contacts the rubber belt, an arc-shaped observation window is opened at one end of the fixed shaft 362. By controlling the reverse rotation of the two moving support rollers 13 and the fixed support roller 21, the wear resistance of the rubber belt can be detected and the annular rubber belt can be balanced in force. At this time, if the friction forces between the rubber belt and the two moving support rollers 13 and the fixed support roller 21 are different, the rubber belt will shift, causing the friction roller 33 to deflect relative to the rotating shaft 35. The relative deflection angle between the rotating shaft 35 and the friction roller 33 can be read through the observation window to judge the difference in wear resistance at different positions on the rubber belt.

[0026] Figure 9 This is a schematic diagram of the state for detecting the tensile strength of the strip rubber belt in this application. The two ends of the strip rubber belt are clamped by the moving support roller 13 and the fixed support roller 21, and the two moving support rollers 13 and the fixed support roller 21 are rotated in the opposite direction to apply tensile forces to the strip rubber belt towards both ends respectively. During this process, by controlling the rotation of the friction roller 33, the wear resistance of the strip rubber belt under tension can be detected. By rotating the two moving support rollers 13 and the fixed support roller 21 in the same direction, the strip rubber belt can also be conveyed to switch the detection position of the rubber belt; Figure 10 This is a schematic diagram of the state when simulating the working conditions of the annular rubber belt in this application. By simulating the use process of the annular rubber belt, various properties of the rubber belt can be detected. It should be noted that at this time, the moving support roller 13 rubs against the inner wall of the annular rubber belt, and the influence caused by the friction on the inner wall during the operation of the annular rubber belt can be tested. If it is necessary to avoid the friction between the moving support roller 13 and the rubber belt, the moving support roller 13 and the worm wheel 22 fixed thereto are fixed by bolts. By loosening the bolts, the moving support roller 13 can rotate relative to the worm wheel 22, so that when the annular rubber belt runs, the moving support roller 13 can rotate under the friction force, reducing the friction between the moving support roller 13 and the rubber belt.

[0027] Figure 11 This is a schematic diagram of the state for detecting the wear resistance difference at different positions of the annular rubber belt in this application. During this process, the two moving support rollers 13 and the fixed support roller 21 rotate in opposite directions. When the friction forces between the annular rubber belt and the two moving support rollers 13 and the fixed support roller 21 are the same, the annular rubber belt will not rotate due to the balanced force. When the wear resistance of the contact positions between the annular rubber belt and the two moving support rollers 13 and the fixed support roller 21 is inconsistent, the balanced force will be broken, and at this time, the annular rubber belt will shift, and then drive the friction roller 33 to deflect.

[0028] In each of the above states, by adjusting the position of the friction roller 33, the friction roller 33 can also be used to support the rubber belt, change the shape of the rubber belt, test the tensile properties and wear resistance of the rubber belt under different shapes, and detect the wear resistance of the rubber belt under different states by controlling the rotation of the friction roller 33.

[0029] Working principle: When detecting the strip-shaped rubber belt, pass the strip-shaped rubber belt through between the two moving support rollers 13 and the fixed support roller 21, control the electric telescopic rod 14 to extend to drive the slider 12, the moving support roller 13, the worm wheel 22 and the moving worm 242 to move downward until the moving support roller 13 and the fixed support roller 21 clamp the strip-shaped rubber belt. Then start the motor 11, and the motor 11 drives the fixed worm 23, the fixed seat 251, the first insert block 254, the connecting rod 252, the square rod 241 and the moving worm 242 to rotate. Then, through the transmission of the two worm wheels 22, the two moving support rollers 13 and the two fixed support rollers 21 are driven to rotate in opposite directions to test the tensile properties of the strip-shaped rubber belt. By changing the rotation direction of the driving shaft of one of the motors 11, the two moving support rollers 13 and the two fixed support rollers 21 can be rotated in the same direction, and the strip-shaped rubber belt can also be conveyed to adjust the detection position of the rubber belt; When detecting the annular rubber belt, the annular rubber belt is sleeved on two moving support rollers 13 and a fixed support roller 21. The distance between the moving support roller 13 and the fixed support roller 21 is controlled to increase by extending the moving support roller 13, so that the moving support roller 13 and the fixed support roller 21 stretch and tighten the annular rubber belt, and the tensile resistance of the annular rubber belt is detected. At this time, by controlling the two moving support rollers 13 and the two fixed support rollers 21 to rotate in opposite directions, the wear resistance of the annular rubber belt can be detected. After rotating the threaded rotating rod 363 to drive the second insert block 364 to disengage from the connecting member 365, the friction roller 33 is no longer driven by the motor 361. At this time, the friction roller 33 is attached to the annular rubber belt. When the annular rubber belt deviates, the friction roller 33 will rotate under the action of friction force. By observing the deflection angle between the friction roller 33 and the rotating shaft 35, it can be judged whether the wear resistance of different positions on the annular rubber belt is consistent; Start the electromagnet 262 to drive the first insert block 254 and the magnetic block 261 to disengage from the connecting rod 252 through magnetic attraction. At this time, the fixed seat 251 rotates and no longer drives the connecting rod 252 to rotate, and the motor 11 no longer drives the moving support roller 13 to rotate. At this time, by rotating the two fixed support rollers 21 in the same direction, the annular rubber belt can be made to rotate cyclically on the moving support roller 13 and the fixed support roller 21 to simulate the actual working conditions of the rubber belt for detection; Rotate the threaded rod 32 to drive the movable frame 31 to lift inside the housing 10, and adjust the position of the friction roller 33 according to the positions of the moving support roller 13 and the fixed support roller 21, so that the two friction rollers 33 can be located in the middle of the annular rubber belt. Then rotate the bidirectional lead screw 343 to drive the two threaded barrels 342, the mounting seat 341 and the friction rollers 33 to move towards or away from each other, so that the two friction rollers 33 can contact the annular rubber belt supported by the passive support roller 13 and the fixed support roller 21, apply pressure to the rubber belt, and assist in the detection of the rubber belt; Rotate the threaded rotating rod 363 in the reverse direction to drive the second insert block 364 to be embedded in the connecting member 365. Start the motor 361, and through the connecting member 365, the second insert block 364 and the fixed shaft 362, the friction roller 33 can be driven to rotate to polish the surface of the rubber belt and test the wear resistance of each position on the rubber belt.
