[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution: a modified plastic production auxiliary material adding device, including a frame 100 and a quantitative material transfer mechanism 200 fixedly installed on the frame 100, and a feed pipe 300 and a blanking pipe 400 respectively assembled in the middle of the top surface and the right side of the bottom surface of the quantitative material transfer mechanism 200. The quantitative material transfer mechanism 200 includes a housing 310 and a cylinder 320, and a slider 330 slidably installed in the housing 310. The left and right sides of the housing 310 are respectively encapsulated with a first end plate 340 and a second end plate 350. The cylinder 320 is fixedly installed along the length direction of the housing 310 on the outside of the second end plate 350. The output end of the cylinder 320 penetrates through the second end plate 350 and is fixedly connected to the slider 330. A first material hole 360 and a second material hole 370 are respectively opened in the middle of the top surface and the right side of the bottom surface of the housing 310. The first material hole 360 is coaxially docked with the feed pipe 300, and the second material hole 370 is coaxially docked with the blanking pipe 400. A columnar material chute 380 is opened on the right side of the top of the slider 330.

[0029] Based on the above structure settings, the auxiliary material adding device for modified plastics production is composed of a frame 100, a quantitative material transfer mechanism 200, a feed pipe 300, and a discharge pipe 400. Among them, the frame 100 provides structural support for the quantitative material transfer mechanism 200. The quantitative material transfer mechanism 200 cooperates with the feed pipe 300 and the discharge pipe 400 to achieve the quantitative addition of auxiliary materials for modified plastics production. Specifically, during the working process, the auxiliary materials are input into the quantitative material transfer mechanism 200 through the feed pipe 300. When the output end of the cylinder 320 is at the maximum extended stroke position, the material trough 380 is coaxially distributed with the first material hole 360. The auxiliary materials fall into the material trough 380 through the first material hole 360 and fill the material trough 380. Subsequently, the output end of the cylinder 320 resets, and the slider 330 moves to the right until the output end of the cylinder 320 is completely reset. The left side of the slider 330 blocks the first material hole 360. The material trough 380 on the right side of the slider 330 is coaxially distributed with the second material hole 370. The auxiliary materials filling the material trough 380 are output through the discharge pipe 400 through the second material hole 370. By reciprocating the output end of the cylinder 320, the intermittent quantitative feeding of the auxiliary materials can be achieved. The auxiliary material adding device for modified plastics production, by setting the quantitative material transfer mechanism 200, can drive the slider 330 to move horizontally within the housing 310 under the drive of the telescopic movement of the output end of the cylinder 320, so as to cooperate with the material trough 380 to achieve the quantitative discharging of the auxiliary materials for modified plastics production, ensuring the accuracy of the feeding amount of the auxiliary materials.

[0030] Furthermore, two clamping plates 390 for flange edge embedding of the feed pipe 300 or the discharge pipe 400 are welded to the top and bottom of the housing 310 respectively. The two clamping plates 390 are symmetrically distributed, and the tops of both are threadedly penetrated by fastening screws 3910 distributed in the vertical direction. Among them, the two symmetrically distributed clamping plates 390 form a receiving groove for flange edge embedding of the feed pipe 300 or the discharge pipe 400. Specifically, the operator tightens the fastening screws 3910, and one end of the fastening screw 3910 presses against the flange edge of the feed pipe 300 or the discharge pipe 400, so as to limit and fix the feed pipe 300 or the discharge pipe 400. The disassembly and assembly are convenient, ensuring the sealing performance of the assembly of the feed pipe 300 or the discharge pipe 400.

[0031] Further, it further includes a rotary discharger 500 with a flange assembled at the input end of the feed pipe 300. The rotary discharger 500 includes a cylinder body 510 and closing plates 520 welded to both ends of the cylinder body 510, and two pipe bodies 530 respectively penetrating and welded to the top and bottom of the cylinder body 510 and distributed coaxially. Mounting plates 540 are welded to the top and bottom of both closing plates 520, and a servo motor 550 is fixedly installed on the outer side of one of the closing plates 520. The output end of the servo motor 550 penetrates through the closing plate 520 and is fixedly connected to a shaft rod 560. The shaft rod 560 is rotatably mounted inside the cylinder body 510 and a star wheel 570 is fixedly sleeved outside it. Among them, by assembling the rotary discharger 500 at the input end of the feed pipe 300, on the one hand, it can cooperate with the star wheel 570 driven by the servo motor 550 to further control the feeding, and on the other hand, it can avoid the blockage phenomenon when the auxiliary materials are input into the quantitative material transfer mechanism 200.

[0032] Further, the outer ends of the pipe bodies 530 penetrate through the mounting plates 540 in the vertical direction, and the outer walls of the pipe bodies 530 are fitted and adapted to the inner walls of the feed pipe 300. Among them, the pipe bodies 530 are designed to be lengthened and extended. The pipe body 530 located at the bottom of the cylinder body 510 extends into the feed pipe 300 and is adapted to the feed pipe 300 to ensure the sealing performance of the assembly of the rotary discharger 500 at the input end of the feed pipe 300.
