[0031] As a further solution of this example, the mixed rubber comprehensive performance testing device also includes a release agent spraying component 2, which includes a release agent box 201, a delivery pipe 202, and a spraying pipe 203; the release agent box 201 is used to contain the release agent; one end of the delivery pipe 202 is connected to the release agent box 201, and the other end is connected to the spraying pipe 203; the spraying pipe 203 is arranged between the upper layer of cellophane and the lower layer of cellophane, and a one-way valve is provided inside the delivery pipe 202 and the spraying pipe 203, and the release agent is sprayed on the opposite surfaces of the upper layer of cellophane and the lower layer of cellophane.

[0032] As a further solution of this example, the release agent spraying assembly 2 also includes a stirring shaft 204 and a first rotating disk 205.

The stirring shaft 204 is provided with a pulley, which is connected to the first rotating disk 205 through a belt, and drives the stirring shaft 204 to perform stirring when the first rotating disk 205 rotates.

[0033] As a further solution of this example, the mixed rubber comprehensive performance detection device also includes a mixed rubber 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. Among them, the second motor 701 provides power; the receiving reel 702 is arranged on one side of the cutting assembly 5 and is connected to the second motor 701 by transmission; the feeding reel 703 is arranged on the other side of the cutting assembly 5; the conveyor belt assembly 704 is arranged on one side of the cutting assembly 5 of the receiving reel 702; the conveyor belt assembly 704 is connected to the stirring shaft 204 by transmission; and the conveying robot 705 is used to move the mixed rubber on the conveyor belt assembly 704 to the glass paper of the lower winding assembly.

[0034] The working principle of the comprehensive performance testing device for mixed rubber in this application: 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 passes through the through slot and is fixed on the surface of the take-up reel 702; 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.

[0035] Then, the first motor 401 is started, and the output end of the first motor 401 drives the drive shaft 403 to rotate through the transmission belt, and the drive shaft 403 drives the first drive disk 404 and the second drive disk 405 at both ends to rotate. During the rotation of the first drive disk 404, the first drive plate 406 is controlled to slide back and forth on the surface of the support body 3 through the first protrusion 4041, and the first transmission shaft 408 is driven to rotate back and forth when it slides. The second drive disk 405 at the other end has the same motion principle, and drives 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 movement directions of the first drive plate 406 and the second drive plate 407 are opposite, and the arc surface at the upper end of the first transmission shaft 408 and the second transmission shaft 409 are opposite to the structure of the vertical surface, that is, when the drive shaft 403 rotates, the first transmission shaft 408 and the second transmission shaft 409 respectively control the movement modes of the first matching shaft 503 and the second matching shaft 603 in opposite directions.

[0036] 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 matching shaft 503 below the cutting component 5. At this time, the first matching shaft 503 slides upward inside the limit block 501. The first matching shaft 503 can be connected to the limit block 501 by sliding up and down through the splines or straight grooves 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 matching shaft 603 below the fluidity detection component 6 reverses. At this time, the second transmission shaft 409 contacts the vertical surface of the second matching shaft 603, driving the second matching shaft 603 to rotate.

[0037] Furthermore, when the first mating shaft 503 below the cutting assembly 5 slides upward, the connecting seat 501 is driven to move upward synchronously. The connecting seat 501 moves upward and drives the cutting ring 502 to circularly cut the mixed rubber strip inside the through groove through the pressure sensor 5112. At the same time, during the cutting process, the shear resistance of the mixed rubber is judged by the pressure fed back to the pressure sensor 504 by the cutting ring 502. At the same time, the connection seat 501 drives the hardness detector 801 to move upward synchronously, and the hardness of the surface of the original mixed rubber material is tested while cutting. A brush 802 is arranged around the hardness detector 801. When the hardness detector 801 moves up and down, the brush 802 can automatically clean the surface of the hardness detector 801 to avoid residual glue sticking to the surface of the hardness detector 801, which affects the subsequent detection effect and improves the detection accuracy.

[0038] 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 second transmission rod 306 to rotate through the transmission belt during the rotation process, and the second transmission rod 306 drives the lower material collection roll 304 to rotate during the rotation process, and the lower material collection roll 304 drives the upper material collection roll 302 to rotate through the transmission belt, and pulls the cellophane in the upper material collection roll 301 and the lower material collection roll 303 during the rotation process, wherein the cellophane in the upper material collection roll 303 and the lower material collection roll 303 is provided with 3 layers, which is not easily damaged, and the transmission ratio of the lower material collection roll 304 to the upper material collection roll 302 is 2:1, and during the pulling process, there is a difference in the pulling speed of the cellophane in the upper material collection roll 301 and the lower material collection roll 302, so that the tested mixed rubber can be separated better and faster.

[0039] During the continuous rotation of the first driving disk 404 and the second driving disk 405, when the first driving plate 406 below the cutting component 5 moves in the direction away from the first driving 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 501, and the second mating shaft 603 below the fluidity detection component 6 will move upward.

[0040] When the first mating shaft 503 below the cutting component 5 rotates, the first rotating disk 205 is driven to rotate. The first rotating disk 205 drives the stirring shaft 204 to rotate through the transmission belt, and stirs 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 convey the cut mixed rubber.

[0041] 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 rubber from being deformed by instantaneous high temperature and affecting the detection efficiency.

[0042] 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 a 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.

[0043] 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 to pull the mixed rubber on the feeding reel 703 through the transmission belt, and performs sensing control through the sensor. When the cutting ring 502 moves upward, the second motor 701 is turned off. At this time, the cutting ring 502 cuts the original mixed rubber, and at the same time, the hardness and shear resistance performance are tested; At this time, the lower take-up roll 304 and the upper take-up roll 302 pull the glass paper to remove the previous group of tested mixed rubber; the mixed rubber above the pulled glass paper falls into the inside of the recovery box 9 for collection.

[0044] 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 rubber mix again. During the pulling process, the cut rubber mix is ​​pulled out, and the discarded rubber mix is ​​rolled up by the receiving reel 702. The cut rubber mix to be tested automatically falls onto the surface of the conveyor belt assembly 704 by its gravity and is then transported; when the rubber mix 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.

[0045] At this time, the rubber mix to be tested is transported by the transport robot 705 , and after being adsorbed by the suction cup of the transport robot 705 , the rubber mix to be tested is placed on the upper surface of the cellophane of the lower material roll 303 just above the testing tank 602 .

[0046] At this time, after the tray 601 moves upward, the first motor 401 stops, so there is sufficient time to preheat and detect the cellophane and the mixed rubber to be tested; when the detector 604 is testing, the internal test hydraulic cylinder of the detector 604 moves downward for detection, and the height of the internal test hydraulic cylinder of the detector 604 decreases over time to reflect the flow rate of the mixed rubber, 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 device for detecting the mixed rubber.

[0047] Furthermore, during the operation of the winding assembly 3 , the release agent is sprayed onto the surface of the glass paper through the conveying pipe 202 and then through the spraying pipe 5014 .

[0048] The above-mentioned embodiments only express the implementation methods of the present invention, and cannot be understood as limiting the scope of the invention patent, nor is it any form of limitation on the structure of the present invention. It should be pointed out that for ordinary technicians in this field, several changes and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
