The bottom surface of the sealing ring 2 is overlapped with a limit ring 4, and the inner ring surface of the limit ring 4 is slidably connected with the transmission rod 3.

[0028] The limiting ring 4 is set to fix the longitudinal moving path of the transmission rod 3, and the upper scrapers 5 are fixedly connected to the two side surfaces of the limiting ring 4, and the adjacent sides of the two upper scrapers 5 are fixedly connected to the limiting ring 4, and the two end surfaces of the upper scraper 5 are fixedly connected to the side scrapers 6, and the adjacent sides of the two side scrapers 6 are fixedly connected to the lower scraper 7, so that the two upper scrapers 5 and the two side scrapers 6 and a limiting ring 4 and a lower scraper 7 are combined into a closed loop, which further improves the functional structural stability of the equipment, and the inner top wall, the inner bottom wall and the side wall of the reactor body 1 are in sliding and frictional contact with the upper scraper 5, the lower scraper 7 and the side scraper 6 respectively, so that the PUR glue liquid raw material adhered to the inside of the reactor body 1 can be scraped off by the upper scraper 5, the lower scraper 7 and the side scraper 6, thereby improving the stirring and mixing effect of the PUR glue liquid raw material inside the reactor body 1.

[0029] The side scraper 6 is slidably connected to the limit block 8 near the lower scraper 7 through the opened slide groove to fix the longitudinal movement path of the limit block 8. The two limit blocks 8 are fixedly connected to the adjacent sides with connecting plates 9 to fix the longitudinal movement path of the connecting plates 9. The top of the connecting plate 9 is fixedly connected to the transmission rod 3 to achieve synchronous rotation of the connecting plate 9 and the transmission rod 3. A number of stirring plates 10 are fixedly connected to the side of the transmission rod 3, so that the transmission rod 3 drives the several stirring plates 10 to rotate and stir the PUR glue liquid raw material, thereby driving the connecting plate 9 to rotate. At the same time, it is convenient to realize the longitudinal movement of the connecting plate 9, thereby improving the structural flexibility of the equipment parts.

[0030] The two ends of the top of the reactor body 1 are fixedly connected with support plates 12, and the support plates 12 are provided to provide support. The side of the support plate 12 is embedded with a fixed limit bearing 13 to fix the position of the limit bearing 13. The inner ring of the limit bearing 13 is interference-fitted with a rotating block 14. The limit bearing 13 is provided to fix the rotation position of the rotating block 14 and reduce the rotation resistance of the rotating block 14. The end face of the rotating block 14 is fixedly connected with a rotating plate 15, and the side of the rotating plate 15 close to the rotating block 14 is overlapped with the support plate 12, and the rotating plate 15 is located between the two support plates. On one side adjacent to 12, the two rotating plates 15 are fixedly connected with movable rods 16 on the adjacent sides, and the rotating blocks 14 and movable rods 16 fixedly connected on both sides of the rotating plate 15 are staggered, so that when the rotating block 14 rotates, the movable rod 16 makes a circular motion with the rotating block 14 as the center. The top of the transmission rod 3 is fixedly connected with the output shaft of the stirring motor 11, and the stirring motor 11 is provided to provide power. The fixed end of the stirring motor 11 is fixedly connected with a mounting plate 18 to fix the position of the stirring motor 11, and the top of the mounting plate 18 is fixedly connected with a movable plate 17.

[0031] The side of the movable plate 17 is movably connected to the movable rod 16 through the through groove, so that when the movable rod 16 moves horizontally and vertically, it can move and rotate relatively in the inner cavity of the movable plate 17. When the longitudinal movement path of the transmission rod 3 is fixed, the longitudinal reciprocating movement of the movable plate 17 is realized. During the transmission process, the longitudinal stirring positions of the plurality of stirring plates 10 are adjusted to improve the uniform stirring effect on the PUR glue liquid raw material.

[0032] The stirring motor 11 and the rotating motor 19 are both prior arts, and their working principles, sizes and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] How it works

[0034] When using the reactor processing equipment for PUR glue processing, the user introduces PUR glue liquid raw materials into the reactor body 1 through the feed port 20, starts the stirring motor 11, and rotates the output shaft of the stirring motor 11 to drive the transmission rod 3 to rotate, thereby causing a plurality of stirring plates 10 to rotate with the transmission rod 3 as the center of the circle, so as to achieve stirring and mixing of the PUR glue liquid raw materials. At the same time, a connecting plate 9 is fixedly connected to the bottom end of the transmission rod 3, and the limit blocks 8 fixedly connected at both ends of the connecting plate 9 extend into the side scraper 6, so that the transmission rod 3 can rotate while driving the rotation of the two side scrapers 6. During the transmission process, the upper scraper 5, the side scraper 6 and the lower scraper 7 can scrape off the PUR glue liquid raw materials adhered to the reactor body 1, thereby improving the stirring and mixing effect of the reactor processing equipment on the PUR glue liquid raw materials. The limit ring 4 is provided to further improve the longitudinal movement flexibility of the transmission rod 3 and improve the functional structure stability of the equipment.

[0035] Start the rotating motor 19, so that the output shaft of the rotating motor 19 rotates and drives the rotating block 14 to rotate. During the transmission process, the mounting plate 18 drives the stirring motor 11 to move back and forth in the longitudinal direction, thereby realizing the longitudinal reciprocating stirring of the plurality of stirring plates 10 inside the reactor body 1, and preliminarily improving the uniform stirring effect of the PUR glue liquid raw material. The rotating block 14 and the movable rod 16 fixedly connected on both sides of the rotating plate 15 are arranged in a staggered manner, so that the movable rod 16 can rotate and move with the rotating block 14 as the center, thereby realizing the relative rotation and movement of the movable rod 16 in the inner cavity of the movable plate 17. When the longitudinal movement path of the transmission rod 3 is fixed, the longitudinal reciprocating movement stability of the movable plate 17 is realized, and the functional structure stability of the equipment is improved. At the same time, the rotating motor 19 provides a uniform rotation effect, and the longitudinal reciprocating uniform movement of the plurality of stirring plates 10 is realized during the transmission process, further improving the uniform stirring of the PUR glue liquid raw material by the equipment.
