Description

Technical Field

[0002] Rubber compounds are an important part of the development of the rubber industry and are widely used in many fields such as automobiles, electronics, construction, and medical care. With the continuous advancement of technology, the performance and quality of rubber compounds will continue to improve, providing better material support for the development of various industries.

[0003] Patent authorization announcement number CN109187274B discloses a fully automatic mixed film fluidity tester and its testing method, which includes a cellophane conveying device, an extrusion test device, a rotary disk loading device, a SCARA loading robot and a frame. By placing cellophane between the extrusion test device and the mixed film, waste glue is prevented from sticking to the extrusion test device; the mixed film to be tested is pre-set on the rotary disk, and multiple experiments can be carried out by loading it once, ensuring a fast and standardized loading process; the SCARA loading robot and suction cup are used to realize the loading action of the mixed film to be tested, shortening the experimental time.

[0099] As a further embodiment of this embodiment, the device for testing the comprehensive properties of the rubber mix further includes a rubber mix conveying assembly 7, which includes a second motor 701, a receiving reel 702, a feeding reel 703, a conveyor belt assembly 704, and a conveying robot 705. The second motor 701 provides power; the receiving reel 702 is located on one side of the cutting assembly 5 and is in transmission connection with the second motor 701; the feeding reel 703 is located on the other side of the cutting assembly 5; the conveyor belt assembly 704 is located on the side of the receiving reel 702 on the cutting assembly 5; the conveyor belt assembly 704 is in transmission connection with the stirring shaft 204; and the conveying robot 705 is used to move the rubber mix on the conveyor belt assembly 704 onto the cellophane paper on the lower winding assembly.

[0100] The working principle of the comprehensive performance testing device for rubber mix of this application:

[0101] After the discharge port 103 is opened, the feed reel 703 wound with the mixed rubber tape is placed inside it, and the end of the mixed rubber tape is fixed on the surface of the take-up reel 702 after passing through the through slot; the ends of the cellophane on the upper discharge reel 301 and the lower discharge reel 303 are pulled, wherein the end of the cellophane in the upper discharge reel 301 is fixed to the surface of the upper take-up reel 302, and the end of the cellophane on the surface of the lower discharge reel 303 is fixed to the surface of the lower take-up reel 304.

[0102] Next, the first motor 401 is started. The output end of the first motor 401 rotates the drive shaft 403 via a transmission belt. The drive shaft 403 then rotates the first drive disc 404 and the second drive disc 405 at both ends. During the rotation of the first drive disc 404, the first protrusion 4041 controls the first drive plate 406 to slide back and forth on the surface of the support body 3, while simultaneously driving the first transmission shaft 408 to rotate back and forth as it slides. The second drive disc 405 at the other end operates on the same principle, driving the second transmission shaft 409 to rotate back and forth. However, due to the opposite positions of the first protrusion 4041 and the second protrusion 4051, the first drive plate 406 and the second drive plate 407 move in opposite directions. Furthermore, the curved surfaces at the upper ends of the first transmission shaft 408 and the second transmission shaft 409 are arranged in opposite directions relative to the vertical plane. Therefore, when the drive shaft 403 rotates, the first transmission shaft 408 and the second transmission shaft 409 respectively control the first mating shaft 503 and the second mating shaft 603 to move in opposite directions.

[0103] Specifically, when the first driving plate 406 below the cutting component 5 moves toward the direction of the first driving disk 404, the first transmission shaft 408 reverses. When the first transmission shaft 408 reverses, it contacts the arc surface of the first mating shaft 503 below the cutting component 5. At this time, the first mating shaft 503 slides upward inside the limit block 505. The first mating shaft 503 can be connected to the limit block 501 for sliding up and down through the spline or straight groove on its surface. At this time, the second driving plate 407 below the fluidity detection component 6 moves away from the second driving disk 405, and the second mating shaft 603 below the fluidity detection component 6 reverses. At this time, the second transmission shaft 409 contacts the vertical surface of the second mating shaft 603, driving the second mating shaft 603 to rotate.

[0104] Furthermore, when the first mating shaft 503 below the cutting assembly 5 slides upward, it drives the connecting seat 501 to move upward synchronously. The upward movement of the connecting seat 501 drives the cutting ring 502 upward through the pressure sensor 504 to circularly cut the mixed rubber strip inside the through groove. At the same time, during the cutting process, the pressure fed back to the pressure sensor 504 by the cutting ring 502 is used to determine the shear resistance of the mixed rubber strip.

[0105] At the same time, the connector 501 drives the hardness detector 801 upward, testing the hardness of the mixed film surface during cutting. A brush 802 is positioned around the hardness detector 801. As the hardness detector 801 moves up and down, the brush 802 automatically cleans the surface of the hardness detector 801, preventing residual adhesive from sticking to the surface and affecting subsequent testing results, thereby improving test accuracy.

[0106] When the second mating shaft 603 below the fluidity detection component 6 rotates, the second mating shaft 603 drives the second rotating disk 305 to rotate through the spline or straight groove, and controls the rotation of the second transmission rod 306 through the transmission belt during the rotation process. The second transmission rod 306 drives the lower take-up roll 304 to rotate during the rotation process, and the lower take-up roll 304 drives the upper take-up roll 302 to rotate through the transmission belt. During the rotation process, it pulls the cellophane in the upper unloading roll 301 and the lower unloading roll 303, wherein the cellophane in the upper unloading roll 303 and the lower unloading roll 303 is provided with 3 layers, which is not easily damaged, and the transmission ratio of the lower take-up roll 304 to the upper take-up roll 302 is 2:1. During the pulling process, there is a difference in the pulling speed of the cellophane in the upper unloading roll 301 and the lower unloading roll 302, so the mixed film after the test can be separated better and faster.

[0107] During the continuous rotation of the first drive disk 404 and the second drive disk 405, when the first drive plate 406 below the cutting component 5 moves in the direction away from the first drive disk 404, the first mating shaft 503 below the cutting component 5 rotates. At this time, the spline or straight groove of the first mating shaft 503 is disengaged from the limit block 505, and the second mating shaft 603 below the fluidity detection component 6 will move upward.

[0108] When the first mating shaft 503 below the cutting assembly 5 rotates, it drives the first rotating disk 205 to rotate, and the first rotating disk 205 drives the stirring shaft 204 to rotate through the transmission belt, stirring the release agent inside the release agent box 201 to prevent its precipitation and affect the uniformity; at the same time, the stirring shaft 204 rotates the conveyor belt assembly 704 to operate and transport the cut mixed rubber.

[0109] When the second mating shaft 603 below the fluidity detection component 6 moves upward, the mating shaft 603 drives the tray 601, the detection slot 602 and the heater 605 to move upward, preheating the cellophane and the mixed material on the lower material roll 303, so as to prevent the cellophane and the mixed film from being deformed by instantaneous high temperature and affecting the detection efficiency.

[0110] The first transmission shaft 408 and the second transmission shaft 409 have one or two right-angled surfaces at their upper ends. When the first transmission shaft 408 and the second transmission shaft 409 have one right-angled surface at their upper ends and the two right-angled surfaces are located in the same plane, when the first transmission shaft 408 and the second transmission shaft 409 rotate one circle, the first drive disk 404 and the second drive disk 405 complete a 180° rotation. When the first transmission shaft 408 and the second transmission shaft 409 have two right-angled surfaces, when the first transmission shaft 408 and the second transmission shaft 409 rotate one circle or half a circle, the first drive disk 404 and the second drive disk 405 complete a 180° rotation.

[0111] The specific implementation process is as follows: the second motor 701 is started, and the output end of the second motor 701 controls the receiving reel 702 through the transmission belt to pull the mixed rubber tape on the feeding reel 703, and the sensor is used for sensing control. When the cutting ring 502 moves upward, the second motor 701 is turned off. At this time, the cutting ring 502 cuts the mixed rubber tape, and the hardness and shear resistance performance are tested at the same time;

[0112] At this time, the lower take-up roll 304 and the upper take-up roll 302 pull the cellophane roll to remove the previous group of tested mixed films; the mixed films above the pulled cellophane fall into the interior of the recycling box 9 for collection.

[0113] When the stirring shaft 204 rotates the conveyor belt assembly 704 to operate, the second motor 701 is started again, and the receiving reel 702 pulls the mixed tape again. During the pulling process, the cut mixed film is pulled out, and the discarded mixed tape is wound up by the receiving reel 702, and the cut mixed film to be tested automatically falls onto the surface of the conveyor belt assembly 704 by its gravity and is then transported; when the mixed film to be tested is transported to the other side of the conveyor belt assembly 704, the second motor 701 and the first motor 401 stop moving.

[0114] At this time, the mixed film to be tested is transported by the transport robot 705 , and after being adsorbed by the suction cup of the transport robot 705 , the mixed film to be tested is placed on the upper surface of the cellophane of the unwinding roll 303 just above the testing tank 602 .

[0115] At this time, after the tray 601 moves upward, the first motor 401 stops, so there is sufficient time to preheat and test the cellophane and the mixed rubber sheet to be tested; when the detector 604 is testing, the internal test hydraulic cylinder of the detector 604 moves downward for detection, and the flow rate of the mixed rubber is reflected by the height of the internal test hydraulic cylinder of the detector 604 falling over time, and a mixed rubber flow rate curve is drawn in real time. When a plateau period appears, the value at this time is a reference value, which is used to characterize the fluidity of the mixed rubber; when the detection is completed, the first motor 401 is started again to perform the next set of detection operations, so as to realize the continuity of the mixed rubber detection of the device.

[0116] Furthermore, during the operation of the winding assembly 3 , the release agent is sprayed onto the surface of the glass paper through the delivery pipe 202 and then through the spray pipe 5014 .

[0117] The above-described embodiments merely illustrate the implementation methods of the present invention and are not to be construed as limiting the scope of the invention, nor are they to impose any formal limitations on the structure of the present invention. It should be noted that a person skilled in the art may make various changes and improvements without departing from the scope of the present invention, and all such changes and improvements fall within the scope of protection of the present invention.
