Description

Technical Field

[0001] The utility model belongs to the technical field of rubber particle detection, and particularly relates to a regenerated rubber particle detection device. Background Art

[0002] In the rubber industry, the use of recycled rubber particles has become an important means to improve resource utilization efficiency and environmental protection. However, the quality of recycled rubber particles directly affects the effect of their reuse. Wear resistance is one of the key properties of rubber products, which directly affects their service life and safety. By testing the wear resistance of rubber particles, it is possible to evaluate whether their quality meets the relevant standards and requirements, thereby ensuring the stable and reliable quality of rubber products.

[0003] The Chinese utility model patent currently announced as: CN216117065U discloses a rubber wear-resistant detection device, which is provided with a shell, a moving block is movably connected inside the shell, and fixing bolts are movably connected to the left and right sides of the moving block. A compression spring is fixedly connected to the top of the moving block, a worm is fixedly connected to the top of the compression spring, a turntable is fixedly connected to the top of the worm, and a trigger mechanism is fixedly connected to the top of the moving block. The moving block moves upward, thereby driving the trigger mechanism to move upward together, so that the trigger mechanism contacts the contact point. At this time, the external driving source stops working, and then the workbench stops moving. At this time, the moving block moves upward, causing the compression spring to be compressed and deformed, thereby compressing the inside of the compression spring, and then the extrusion force between the rubber material and the workbench returns to the initial state, so that when the friction force is reduced, the force is automatically adjusted to prevent affecting the wear resistance detection effect.

[0004] When this patent is used, it is necessary to wrap the rubber material around the moving block, and use the moving block to drive the rubber material to move, so as to test the wear resistance of the rubber material. However, it can only be applied to the testing of rubber, and cannot be applied to the rubber particles after production. Utility Model Content

[0005] The utility model aims to provide a regenerated rubber particle detection device, which solves the problem that an existing regenerated rubber particle detection device needs to wrap a rubber material with a moving block, and the rubber material is driven to move by the moving block, so as to detect the wear resistance of the rubber material, but the device can only be used for the detection of rubber, and cannot detect rubber particles after production.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a regenerated rubber particle detection device, comprising a mounting frame and a bottom plate, the mounting frame is provided with a wear-resistant detection mechanism, and the bottom plate is provided with a slidable collection mechanism;

[0007] The wear-resistant detection mechanism includes a rotating cylinder, a motor, a rotating cavity, a through groove, a rotating ring, a first movable block, a second movable block, a first friction layer, a second friction layer and a rotating sleeve. The rotating cylinder is rotatably arranged between two mounting frames, the motor is arranged on the rotating frame and connected to the rotating cylinder, the rotating cavity is arranged in the inner wall of the rotating cylinder, the through groove is arranged on the inner wall of the rotating cylinder and penetrates into the rotating cavity, the number of the through grooves is two and they are symmetrically arranged, the rotating ring is arranged in the rotating cavity, the first movable block and the second movable block are elastically arranged on the rotating ring, the first friction layer is arranged on the inner wall of the rotating cylinder and the first movable block, the second friction layer is arranged on the second movable block, the first movable block and the second movable block are consistent with the cross-section of the through groove, the rotating sleeve is arranged on the rotating ring and extends to the outside of the rotating cylinder, and the friction coefficient of the second friction layer is greater than the friction coefficient of the first friction layer.

[0008] The above technical scheme is adopted, by setting a mounting frame, a bottom plate, a wear-resistant detection mechanism and a collecting mechanism. When in use, the bottom plate connects the two mounting frames, and then the wear-resistant detection mechanism performs a wear-resistant detection on the rubber particles. After the detection is completed, the rubber particles are collected by the collecting mechanism, wherein the wear-resistant detection mechanism includes a rotating cylinder, a motor, a rotating cavity, a through groove, a rotating ring, a first movable block, a second movable block, a first friction layer, a second friction layer and a rotating sleeve. When in use, the rotating cylinder is first rotated and set between the two mounting frames, and the weighed rubber particles are placed inside the rotating cylinder. The rotating cylinder is driven by the motor to rotate, and the first friction layer is used to collect the rubber particles. The friction layer rubs the rubber particles, and the wear resistance of the rubber particles can be detected through the loss of rubber. Then, the rotating ring is driven by the rotating sleeve to rotate in the rotating cavity. When the first movable block coincides with the through groove, the rubber particles are detected only by the first friction layer. Then, when the second friction layer detects the rubber particles when needed, the rotating ring is driven by the rotating sleeve to rotate in the rotating cavity so that the second movable block coincides with the through groove. At this time, the second friction layer on the second movable block can detect the rubber particles. Since the friction coefficient of the second friction layer is greater than that of the first friction layer, it can simulate the wear resistance of the rubber particles in different environments.

[0009] Further: the collecting mechanism includes a trapezoidal groove, a screw rod, a sliding block, a handle, a mounting plate, a collecting chamber and a filter plate, the trapezoidal groove is arranged on the bottom plate, one end of the screw rod is rotatably arranged on the inner wall of the trapezoidal groove, the other end of the screw rod extends to the outside of the trapezoidal groove, the sliding block is threadedly rotatably arranged on the screw rod, the handle is arranged on the other end of the screw rod, the mounting plate is arranged on the sliding block, the collecting chamber is arranged on the mounting plate, and the filter plate is arranged inside the collecting chamber.

[0010] By adopting the above technical scheme, by setting a trapezoidal groove, a screw rod, a sliding block, a handle, a mounting plate, a collecting chamber and a filter plate, when the rubber particle detection is completed, the rubber particles are discharged from the rotating cylinder and enter the collecting chamber, and then the filter plate in the collecting chamber can filter the debris generated by the detection and retain the complete rubber particles. Then, the screw rod is rotated by the handle, and since the sliding block is rotatably connected to the screw rod thread, the collecting chamber can be moved, and then the collecting chamber is moved out from the bottom of the rotating cylinder, so as to facilitate the collection of the rubber particles after the detection.

[0011] Furthermore: a discharge port is arranged on the rotating cylinder, a sealing cover is hinged on the discharge port, and a handle is arranged on the sealing cover.

[0012] By adopting the above technical solution, by providing a discharge port, a sealing cover and a handle, when in use, the discharge port can be convenient for placing and removing rubber particles, and then the discharge port can be sealed by the sealing cover, and then the handle can provide a fulcrum for the staff.

[0013] Further: a pressing plate is arranged on the rotating cylinder, the pressing plate bypasses the rotating sleeve, and a fixing rod is arranged at the other end of the pressing plate.

[0014] By adopting the above technical solution, a pressure plate, a rotating sleeve and a fixed rod are set. When in use, first one end of the pressure plate is set on the rotating cylinder and bypasses the rotating sleeve. After the adjustment of the rotating sleeve is completed, the pressure plate is fixed to the surface of the rotating cylinder so that the pressure plate presses the rotating sleeve, so that the rotating sleeve cannot continue to rotate.

[0015] Furthermore: a limiting groove is arranged on the bottom plate, the number of the limiting grooves is two and they are symmetrically arranged, a limiting rod is arranged in the limiting groove, a limiting block is slidably arranged on the limiting rod, and the limiting block is connected to the mounting plate.

[0016] By adopting the above technical solution, by setting a limit groove, a limit rod and a limit block, when in use, first the limit groove is set on both sides of the trapezoidal groove. When the collecting chamber moves, the limit block can move on the limit rod, thereby limiting the movement of the collecting chamber.

[0017] Further: a weighing device for weighing is arranged on the bottom plate.

[0018] By adopting the above technical solution, a weighing device is set up. When in use, the weighing device can measure and record the weight of the rubber particles before and after the detection. By comparing the amount of weight loss of the rubber particles during the detection process, the wear resistance of the rubber particles can be understood.

[0019] Furthermore: the rotating sleeve is provided with an anti-skid groove for increasing friction.

[0020] By adopting the above technical solution, the anti-skid groove is provided. When in use, the anti-skid groove can increase the friction between the staff and the rotating sleeve, thereby preventing the staff from slipping.

[0021] Further: support columns are arranged on the lower surface of the base plate, the number of the support columns is four and they are arranged symmetrically, and anti-slip pads are arranged on the support columns.

[0022] By adopting the above technical solution, by setting support columns and anti-skid pads, when in use, the support columns can provide support to the base plate to increase the ground clearance of the base plate, and then the anti-skid pads can increase the friction between the support columns and the ground, further improving the stability of the base plate.

[0023] In summary, the utility model has the following beneficial effects:

The wear resistance of the rubber particles can be detected by the loss of rubber, and then the rotating ring is driven by the rotating sleeve to rotate in the rotating cavity. When the first movable block coincides with the through groove, that is, the rubber particles are detected only by the first friction layer, and then when the second friction layer detects the rubber particles when needed, the rotating ring is driven by the rotating sleeve to rotate in the rotating cavity, so that the second movable block coincides with the through groove. At this time, the second friction layer on the second movable block can detect the rubber particles. Since the friction coefficient of the second friction layer is greater than that of the first friction layer, the wear resistance of the rubber particles in different environments can be simulated.

[0025] By setting up a weighing device, when in use, the weighing device can measure and record the weight of the rubber particles before and after the test. By comparing the amount of weight loss of the rubber particles during the test process, the wear resistance of the rubber particles can be understood.

[0026] Based on the above improvements, the overall technical effect achieved by the device is to enable rubber particles to contact surfaces with different friction coefficients, and then measure the wear resistance of the rubber particles through the reduced weight of the rubber particles, and can detect rubber particles with smaller volumes.

[0048] Brief description of the usage process:

[0049] When in use, first, the rotating cylinder 301 is rotatably arranged between the two mounting frames 1, and the weighed rubber particles are put into the rotating cylinder 301. The rotating cylinder 301 is driven to rotate by the motor 302, and the rubber particles are rubbed by the first friction layer 308.

Then, the filter plate 407 in the collecting chamber 406 can filter the debris generated by the detection and retain the complete rubber particles. Then, the screw rod 402 is rotated by the handle 404. Since the sliding block 403 is threadedly connected to the screw rod 402, the collecting chamber 406 can be moved, and then the collecting chamber 406 is moved out from the bottom of the rotating cylinder 301, so as to collect the rubber particles after the detection.
