[0008] The fixing mechanism includes a fixing seat, which is symmetrically arranged on the outside of the feeding bin. The cover plate is provided with a connecting rod penetrating the cover plate at a symmetrical position on the top of the cover plate. A sleeve shaft is rotatably installed in the middle of the fixing seat, and the sleeve shaft is adapted to the connecting rod.

[0009] As an improved technical solution, the fixing mechanism further includes baffles, which are symmetrically arranged inside the fixing seat and sleeved on the outside of the sleeve shaft. A torsion spring is sleeved between the two baffles on the outside of the sleeve shaft, and the two ends of the torsion spring are fixedly connected to the fixing seat and one side baffle, respectively. The inner wall of the opening end of the sleeve shaft is symmetrically provided with locking blocks, and the outer wall of one end of the connecting rod is symmetrically provided with rail grooves that are adapted to the locking blocks.

[0011] As an improved technical solution, the rail groove is L-shaped, the baffle is an annular structure, and the connecting rod is threadedly connected to the cover plate.

[0012] As an improved technical solution, the cleaning assembly includes a mounting bracket, which is fixed to the outer side of the upper end of the rotating shaft. The upper part of the rotating shaft has a transmission groove that communicates with the mounting bracket and the output shaft of the hollow shaft motor. The bottom of the mounting bracket is symmetrically provided with a scraping seat. One side of the scraping seat has a mounting groove. A push plate is slidably provided in the mounting groove. The push plate is symmetrically provided with a telescopic rod on the side away from the opening of the mounting groove.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model can drive the gear ring to rotate via the drive rod, thereby simultaneously driving multiple sleeve shafts to rotate, so that the locking block moves in the rail groove to the position corresponding to the lower opening of the rail groove.

[0030] like Figure 1 - Figure 3 and Figure 5 As shown in the figure, this embodiment provides a feeding device for silicone rubber production, including a frame 1, a feeding bin 2 fixedly embedded in the middle of the frame 1, a cover plate 3 on the top of the feeding bin 2, the cover plate 3 being connected to the feeding bin 2 by a fixing mechanism, a hollow shaft motor 4 on the top of the cover plate 3, and in this example, a feed inlet on one side of the top of the cover plate 3; the output end of the hollow shaft motor 4 is connected to a rotating shaft 5 inside the feeding bin 2, blades 6 are symmetrically arranged on the outer wall of the rotating shaft 5, and a cleaning assembly connected to the rotating shaft 5 is provided inside the feeding bin 2; in this example, a controller is provided on one side of the frame 1, which is prior art and is not shown in the figure; the fixing mechanism includes a fixing seat 11, and the fixing seat 11 is symmetrically arranged on the outside of the feeding bin 2, and a connecting rod 12 penetrating the cover plate 3 is provided at symmetrical positions on the top of the cover plate 3, and a sleeve shaft 13 penetrating the fixing seat 11 is rotatably installed in the middle of the fixing seat 11, and the sleeve shaft 13 is adapted to the connecting rod 12.

[0031] In this example, the fixing mechanism also includes baffles 14, which are symmetrically arranged inside the fixing seat 11 and sleeved on the outside of the sleeve shaft 13. A torsion spring 15 is sleeved between the two baffles 14 on the outside of the sleeve shaft 13, and the two ends of the torsion spring 15 are fixedly connected to the fixing seat 11 and one side baffle 14 respectively. The inner wall of the opening end of the sleeve shaft 13 is symmetrically provided with locking blocks 16, and the outer wall of one end of the connecting rod 12 is symmetrically provided with a rail groove 17 that matches the locking block 16, so as to quickly disassemble and assemble the cover plate 3, thereby facilitating the cleaning of the inside of the feeding bin 2, and also facilitating the inspection and maintenance of its internal components.

[0032] In this example, a toothed ring 18 is rotatably fitted on the outer wall of the feeding bin 2, and several toothed grooves that mesh with the toothed ring 18 are symmetrically opened on the lower outer wall of the sleeve shaft 13. Several drive rods 19 are symmetrically arranged at the bottom of the toothed ring 18 so as to synchronously drive multiple sleeve shafts 13 to rotate, and to conveniently and quickly separate the sleeve shaft 13 from the connecting rod 12.

[0033] In this example, the rail groove 17 is L-shaped, the baffle 14 is an annular structure, and the connecting rod 12 is threadedly connected to the cover plate 3 so as to use the trajectory of the rail groove 17 to restrict the locking block 16 so that the sleeve shaft 13 and the connecting rod 12 can be connected.

[0034] In this example, the lower end of the rotating shaft 5 is fitted with a spiral blade 7 inside the feeding bin 2. A solenoid valve is installed inside the spiral blade 7 on the lower inner wall of the feeding bin 2. A floating plug 8 is movably connected to the lower end of the feeding bin 2. Floating cylinders 9 are symmetrically arranged on the lower outer wall of the feeding bin 2. The telescopic end of the floating cylinder 9 is fixedly connected to the floating plug 8. A gravity sensor 10 is provided at the bottom of the floating plug 8 so as to push the material through the spiral blade 7 to avoid blockage. At the same time, the amount of material fed is controlled and adjusted by the gravity sensor 10.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown in the example, the cleaning assembly includes a mounting bracket 20, which is fixed to the outer side of the upper end of the rotating shaft 5. The upper part of the rotating shaft 5 has a transmission groove communicating with the mounting bracket 20 and the output shaft of the hollow shaft motor 4. The bottom of the mounting bracket 20 is symmetrically provided with scraping seats 21. One side of the scraping seat 21 has a mounting groove, and a push plate 22 slides within the mounting groove. A telescopic rod 23 is symmetrically provided on the side of the push plate 22 away from the opening of the mounting groove. A water spray frame 24 is provided at the end of the push plate 22 away from the telescopic rod 23. The water frame 24 is equipped with several nozzles at one end, and a sealing plate 25 is connected to one side of the cleaning seat 21 at the other end of the water frame 24. Several water spray heads are symmetrically arranged at the bottom of the mounting frame 20 so that during normal cleaning operations, the output end of the hollow shaft motor 4 can be directly connected to one end of the pipe of the external water supply equipment by using the rotating connector without disassembling the cover plate 3, thereby delivering water to the mounting frame 20 and distributing it into the water spray frame 24, so that the water can be sprayed out through the nozzles to rinse and clean the inner wall of the feeding bin 2.

[0036] In this example, one end of the scraper seat 21 is tangent to the inner wall of the feeding bin 2, and the sealing plate 25 is provided with a sealing gasket on the side near the scraper seat 21 so as to scrape the inner wall of the feeding bin 2. The setting of the sealing gasket can improve the sealing between the sealing plate 25 and the scraper seat 21.

[0037] When cleaning or maintenance is required inside the feeding hopper 2, the gear ring 18 can be driven to rotate via the drive rod 19, which, in conjunction with the rail groove 17, drives the sleeve shaft 13 to rotate. The sleeve shaft 13 rotates under the limit of the baffle 14, and simultaneously twists the torsion spring 15. The rotation of the sleeve shaft 13 also causes the locking block 16 to rotate synchronously within the torsion spring 15, so that the locking block 16 moves to the position corresponding to the lower opening of the rail groove 17. Then, pulling up the cover plate 3 causes the connecting rod 12 to separate from the locking block 16, allowing the cover plate 3 to be disassembled. Then, the feeding hopper 2 can be cleaned or maintained. During installation, repeat the above steps to install the cover plate 3. Afterward, release the force applied to the gear ring 18 to reset the locking block 16 within the rail groove 17. The device can be moved to restrict and fix the feeding bin 2 and the cover plate 3, so as to quickly connect and fix them. During normal use, the cover plate 3 can be left unremoved for cleaning of the feeding bin 2. The output end of the hollow shaft motor 4 can be connected to the pipe of the external water supply equipment by using the rotating connector to supply water. At the same time, the hollow shaft motor 4 is started to drive the rotating shaft 5, the mounting bracket 20 and the cleaning seat 21 to rotate synchronously, so that the cleaning seat 21 can clean the inner wall of the feeding bin 2. At the same time, the telescopic rod 23 is activated to push the push plate 22 to move the water spray frame 24 and the sealing plate 25 out of the mounting groove, so that the nozzle and water spray head can spray water to rinse and clean the inner wall of the feeding bin 2. This is convenient for daily cleaning, easy to use and highly practical.

[0038] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
