[0014] A process for adding an auxiliary agent to prepare silicone rubber, using the above-mentioned device for adding an auxiliary agent to prepare silicone rubber, comprises the following steps:

[0015] S1: When preparing silicone rubber, the additive is first added to the addition box. Under the action of gravity, the addition box and the movable plate are driven downward. At the same time, the third spring is compressed. At this time, the distance sensor detects the change in the distance of the movable plate to determine the compression amount of the third spring, thereby controlling the weight of the added additive. Next, the silicone rubber is adhered to the side wall of the adhesion roller. Then, the rolling roller and the adhesion roller are rotated, so that the silicone rubber passes through the gap between the two scrapers and is transported between the rolling roller and the adhesion roller for rolling, forming a thin sheet and continuing to be transported along the adhesion roller;

[0016] S2: Then, the motor is started, and the rotation of the motor drives the rotation of the threaded rod, thereby driving the L-shaped plate to move downward. When the L-shaped plate moves downward, the U-shaped plate and the telescopic mechanism can drive the scraper block to move downward and contact the surface of the adhesion roller. When the thin sheet of silicone rubber is against the side wall of the scraper, it can be scraped and gradually bent toward the middle. When the silicone rubber is against the side wall of the scraper block, it can push the scraper block to move in the direction close to the third connecting block. At the same time, the first sleeve is compressed. At the same time, when the scraper block moves, the first connecting block and the sealing plate can be pushed to move through the second L-shaped block and the first L-shaped block. At the same time, the first spring is compressed, so that the first through hole and the second through hole coincide with each other. At this time, the additive in the addition box can be added to the thin sheet of silicone rubber through the first through hole and the second through hole. At the same time, the greater the amount of silicone rubber, the greater the thrust on the scraper block, and the larger the overlapping area of ​​the first through hole and the second through hole, so that it is convenient to adjust the adding speed of the additive according to the amount of silicone rubber, so that the adding effect is better;

[0017] S3: After the addition is completed, the scraper can make the thin sheet of silicone rubber continue to bend toward the middle and cover the additive, so that the added additive is wrapped in the thin sheet of silicone rubber. Then, it passes through the gap between the two scrapers and continues to be transported to the rolling roller and the adhesion roller for rolling, which prevents it from falling and improves the mixing efficiency and effect, thereby making the addition effect of the additive better.

[0018] S4: When the L-shaped plate moves downward, it can drive the L-shaped frame to move downward synchronously and abut against the top of the adding box, thereby pushing the adding box downward and making the rubber wheel abut against the surface of the adhesion roller. At this time, when the adhesion roller rotates, it can drive the rubber wheel to rotate. When the rubber wheel rotates, it can drive the driving pulley to rotate through the rotating shaft. When the driving pulley rotates, it can drive the driven pulley to rotate through the belt, thereby driving the rotating rod and the stirring rod to rotate, which can automatically stir the additive in the adding box to avoid accumulation and agglomeration, thereby ensuring its addition effect;

[0019] S5: When the rotating rod rotates, it can drive the rotating disk to rotate synchronously. When the conical block contacts the side wall of the pushing block, it can push the moving block and the rubber rod to move toward the adding box. At the same time, the fourth spring is compressed. When the conical block passes over the pushing block, the moving block and the rubber rod can move and reset under the action of the fourth spring. This reciprocating process allows the rubber rod to knock and vibrate the side wall of the adding box back and forth to avoid accumulation and adhesion to the inner wall, thereby ensuring the adding effect.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The device and process for adding auxiliary agents for preparing silicone rubber are provided with a telescopic mechanism, etc. When preparing silicone rubber, the auxiliary agent is first added into the adding box. Under the action of gravity, the adding box and the movable plate can be driven to move downward. At the same time, the third spring is compressed. At this time, the distance sensor detects the distance change of the movable plate to determine the compression amount of the third spring, thereby controlling the weight of the added auxiliary agent. Next, the silicone rubber is adhered to the side wall of the adhesion roller. Then, the rolling roller and the adhesion roller are rotated, so that the silicone rubber passes through the gap between the two scrapers and is transported to the rolling roller and the adhesion roller for rolling, so that it forms a thin sheet and continues to be transported as the adhesion roller continues. Next, the motor is started, and the rotation of the motor drives the rotation of the threaded rod, thereby driving the L-shaped plate to move downward. When the L-shaped plate moves downward, the U-shaped plate and the telescopic mechanism can drive the scraper block to move downward and contact the surface of the adhesion roller. When the thin sheet of silicone rubber hits the side wall of the scraper, it can be scraped up and gradually bent toward the middle. When the silicone rubber is in contact with the side wall of the scraper block, When the scraper arrives, it can push the scraper to move in the direction close to the third connecting block, and at the same time, the first sleeve is compressed. At the same time, when the scraper moves, it can push the first connecting block and the sealing plate to move through the second L-shaped block and the first L-shaped block. At the same time, the first spring is compressed, so that the first through hole and the second through hole coincide with each other. At this time, the additive in the adding box can be added to the thin sheet of silicone rubber through the first through hole and the second through hole. At the same time, the greater the amount of silicone rubber, the greater the thrust on the scraper, and the larger the overlapping area of ​​the first through hole and the second through hole, so that it is convenient to adjust the adding speed of the additive according to the amount of silicone rubber, so that the adding effect is better, and after the adding is completed, under the action of the scraper, the thin sheet of silicone rubber can continue to bend toward the middle and cover the additive, so that the added additive is wrapped in the thin sheet of silicone rubber, and then, after passing through the gap between the two scrapers, it continues to be transported to the space between the rolling roller and the adhesion roller for rolling, so as to avoid falling, and improve the mixing efficiency and effect, so that the adding effect of the additive is better;By setting a stirring mechanism and a vibration mechanism, when the L-shaped plate moves downward, it can drive the L-shaped frame to move downward synchronously and abut against the top of the adding box, thereby pushing the adding box downward and making the rubber wheel abut against the surface of the adhesion roller. At this time, when the adhesion roller rotates, it can drive the rubber wheel to rotate. When the rubber wheel rotates, it can drive the active pulley to rotate through the rotating shaft. When the active pulley rotates, it can drive the driven pulley to rotate through the belt, thereby driving the rotating rod and the stirring rod to rotate, which can The additive inside is automatically stirred to prevent accumulation and caking, ensuring the effective addition. Furthermore, when the rotating rod rotates, it can drive the rotating disk to rotate synchronously. When the conical block abuts the side wall of the push block, it can push the moving block and rubber rod toward the addition box. At the same time, the fourth spring is compressed. When the conical block passes the push block, the moving block and rubber rod can move back to their original position under the action of the fourth spring. This reciprocating movement allows the rubber rod to reciprocate and vibrate the side wall of the addition box, preventing accumulation and adhesion on the inner wall, ensuring the effective addition.

[0043] A process for adding an auxiliary agent to prepare silicone rubber, using the above-mentioned device for adding an auxiliary agent to prepare silicone rubber, comprises the following steps:

[0044] S1: When preparing silicone rubber, the additive is first added to the adding box 12. Under the action of gravity, the adding box 12 and the movable plate 20 can be driven to move downward. At the same time, the third spring 403 is compressed. At this time, the distance sensor 405 detects the distance change of the movable plate 20 to determine the compression amount of the third spring 403, thereby controlling the weight of the added additive. Next, the silicone rubber is adhered to the side wall of the adhesion roller 104. Then, the rolling roller 102 and the adhesion roller 104 are rotated, so that the silicone rubber passes through the gap between the two scrapers 10 and is transported between the rolling roller 102 and the adhesion roller 104 for rolling, so that it forms a thin sheet and continues to be transported along with the adhesion roller 104.

[0045] S2: Then, the motor 905 is started. The rotation of the motor 905 drives the rotation of the threaded rod 904, thereby driving the L-shaped plate 16 to move downward. When the L-shaped plate 16 moves downward, the U-shaped plate 18 and the telescopic mechanism can drive the scraper 19 to move downward and contact the surface of the adhesion roller 104. When the thin sheet of silicone rubber abuts against the side wall of the scraper 10, it can be scraped and gradually bent toward the middle. When the silicone rubber abuts against the side wall of the scraper 19, it can push the scraper 19 to move toward the third connecting block 301. At the same time, the first sleeve 303 is compressed. At the same time, when the scraper When the scraper 19 moves, the second L-shaped block 206 and the first L-shaped block 205 can push the first connecting block 201 and the sealing plate 14 to move. At the same time, the first spring 204 is compressed, so that the first through hole 13 and the second through hole 15 overlap. At this time, the additive in the adding box 12 can be added to the thin sheet of silicone rubber through the first through hole 13 and the second through hole 15. At the same time, the greater the amount of silicone rubber, the greater the thrust on the scraper 19, and the larger the overlapping area of ​​the first through hole 13 and the second through hole 15, so that the adding speed of the additive can be adjusted according to the amount of silicone rubber, so that the adding effect is better.

[0046] S3: After the addition is completed, the scraper 19 can make the thin sheet of silicone rubber continue to bend toward the middle and cover the additive, so that the added additive is wrapped in the thin sheet of silicone rubber. Then, it passes through the gap between the two scrapers 19 and continues to be transported to the rolling roller 102 and the adhesion roller 104 for rolling, which prevents it from falling and improves the mixing efficiency and effect, thereby achieving a better addition effect of the additive.

[0047] S4: When the L-shaped plate 16 moves downward, it can drive the L-shaped frame 17 to move downward synchronously and abut against the top of the adding box 12, thereby pushing the adding box 12 downward and making the rubber wheel 606 abut against the surface of the adhesion roller 104. At this time, when the adhesion roller 104 rotates, it can drive the rubber wheel 606 to rotate. When the rubber wheel 606 rotates, it can drive the driving pulley 603 to rotate through the rotating shaft 602. When the driving pulley 603 rotates, it can drive the driven pulley 604 to rotate through the belt 605, thereby driving the rotating rod 501 and the stirring rod 502 to rotate, and can automatically stir the additive in the adding box 12 to avoid accumulation and agglomeration, thereby ensuring its addition effect.

[0048] S5: When the rotating rod 501 rotates, it can drive the rotating disk 805 to rotate synchronously. When the conical block 806 abuts against the side wall of the pushing block 804, it can push the moving block 701 and the rubber rod 702 to move toward the adding box 12. At the same time, the fourth spring 803 is compressed. When the conical block 806 passes over the pushing block 804, the moving block 701 and the rubber rod 702 can move and reset under the action of the fourth spring 803. This reciprocating process can make the rubber rod 702 knock and vibrate the side wall of the adding box 12 back and forth to avoid accumulation and adhesion to the inner wall, thereby ensuring the effect of adding.

10. A process for adding an auxiliary agent to prepare silicone rubber, using the device for adding an auxiliary agent to prepare silicone rubber according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: When preparing the silicone rubber, the additive is first added into the adding box (12). Under the action of gravity, the adding box (12) and the movable plate (20) can be driven to move downward. At the same time, the third spring (403) is compressed. At this time, the distance change of the movable plate (20) is detected by the distance sensor (405), and the compression amount of the third spring (403) can be determined, thereby controlling the weight of the added additive. Then, the silicone rubber is adhered to the side wall of the adhesion roller (104). Then, the rolling roller (102) and the adhesion roller (104) are rotated, so that the silicone rubber passes through the gap between the two scrapers (10) and is transported between the rolling roller (102) and the adhesion roller (104) for rolling, so that it forms a thin sheet and continues to be transported along with the adhesion roller (104); S2: Then, the motor (905) is started. The rotation of the motor (905) drives the rotation of the threaded rod (904), thereby driving the L-shaped plate (16) to move downward. When the L-shaped plate (16) moves downward, the U-shaped plate (18) and the telescopic mechanism drive the scraper (19) to move downward and contact the surface of the adhesion roller (104). When the thin sheet of silicone rubber abuts against the side wall of the scraper (10), it can be scraped and gradually bent toward the middle. When the silicone rubber abuts against the side wall of the scraper (19), it can push the scraper (19) to move toward the third connecting block (301). At the same time, the first sleeve (30 3) is compressed. At the same time, when the scraping block (19) moves, the first connecting block (201) and the sealing plate (14) can be pushed to move by the second L-shaped block (206) and the first L-shaped block (205). At the same time, the first spring (204) is compressed, so that the first through hole (13) and the second through hole (15) overlap. At this time, the additive in the adding box (12) can be added to the thin sheet of silicone rubber through the first through hole (13) and the second through hole (15). At the same time, the greater the amount of silicone rubber, the greater the thrust on the scraping block (19), and the larger the overlapping area of ​​the first through hole (13) and the second through hole (15); S3: After the addition is completed, the scraper (19) can be used to bend the thin sheet of silicone rubber toward the middle and cover the additive, thereby wrapping the added additive in the thin sheet of silicone rubber. Then, the additive passes through the gap between the two scrapers (19) and is continuously transported to the space between the rolling roller (102) and the adhesion roller (104) for rolling. S4: When the L-shaped plate (16) moves downward, it can drive the L-shaped frame (17) to move downward synchronously and abut against the top of the adding box (12), thereby pushing the adding box (12) to move downward and causing the rubber wheel (606) to abut against the surface of the adhesion roller (104). At this time, when the adhesion roller (104) rotates, it can drive the rubber wheel (606) to rotate. When the rubber wheel (606) rotates, it can drive the driving pulley (603) to rotate through the rotating shaft (602). When the driving pulley (603) rotates, it can drive the driven pulley (604) to rotate through the belt (605), thereby driving the rotating rod (501) and the stirring rod (502) to rotate, and automatically stirring the additive in the adding box (12); S5: When the rotating rod (501) rotates, it can drive the rotating disk (805) to rotate synchronously. When the conical block (806) abuts against the side wall of the pushing block (804), it can push the moving block (701) and the rubber rod (702) to move in the direction close to the adding box (12). At the same time, the fourth spring (803) is compressed. When the conical block (806) passes over the pushing block (804), the moving block (701) and the rubber rod (702) can move and reset under the action of the fourth spring (803). This reciprocating movement can cause the rubber rod (702) to knock and vibrate the side wall of the adding box (12) back and forth.
