[0023] A feeding device for an EVA internal mixer according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a feeding device for an EVA internal mixer, comprising a shell 1, an internal mixer feeding port 17 and a mounting tube 2, wherein the mounting tube 2 is fixedly mounted on the bottom end of the inner wall of the shell 1, and cleaning components are arranged at both ends of the shell 1; the cleaning components include a mounting plate 5, a plurality of cylinders 6, a connecting ring 7, a plurality of cleaning frames 9, a feeding pipe 8, an air jet nozzle 12, a water spray nozzle 13 and a motor 3, mounting grooves are provided at both ends of the mounting tube 2, the motor 3 is fixedly mounted on the wall of the mounting groove, the mounting plate 5 is fixedly mounted on one output end of the motor 3, a plurality of cylinders 6 are fixedly mounted on the top of the mounting plate 5, the connecting ring 7 is fixedly mounted on the output end of the cylinder 6, a plurality of cleaning frames 9 and the feeding pipe 8 are respectively fixedly mounted on the inner walls of the corresponding connecting rings 7, and the air jet nozzle 12 and the water spray nozzle 13 are fixedly mounted on one end of the inner wall of the cleaning frame 9.

[0026] It should be noted that, by setting up a cleaning component, the feeding conveying cylinder 4 can be replaced by rotating the mounting plate 5, and the cleaning frame 9 is rotated to the conveying cylinder 4 that needs to be cleaned for cleaning, which makes cleaning convenient. At the same time, when cleaning the conveying cylinder 4, the feeding device is not affected to feed the materials. The mounting plate 5 is provided to drive the cleaning frame 9 and the feeding pipe 8 to rotate and adjust their positions, and a water spray nozzle 13 is provided to spray high-pressure water to clean the inner wall of the conveying cylinder 4, and a jet nozzle 12 is provided to spray high-pressure air to dry the water stains on the inner wall of the conveying cylinder 4 and discharge them into the drainage frame 15.

[0027] In some embodiments, Figure 3 As shown, a plurality of conveying cylinders 4 are fixedly mounted on the inner wall of the housing 1 , the cleaning frame 9 and the feeding pipe 8 correspond to the conveying cylinders 4 , and the connecting pipe 14 is connected to the corresponding conveying cylinders 4 .

[0028] It should be noted that the motors 3 at both ends of the mounting cylinder 2 can both be servo motors, and the motors 3 at both ends of the mounting cylinder 2 rotate synchronously in the same direction, thereby driving the mounting plate 5 and the drainage frame 15 to rotate synchronously in the same direction. By setting the cylinder 6, the connecting ring 7 can be driven to rise and fall, thereby driving the cleaning frame 9 and the feeding pipe 8 to rise and fall. When the mounting plate 5 and the drainage frame 15 rotate, the cylinder 6 drives the cleaning frame 9 and the feeding pipe 8 to rise. When the rotation adjustment is completed, the cylinder 6 drives the cleaning frame 9 and the feeding pipe 8 to descend, so that one end of the cleaning frame 9 and the feeding pipe 8 is inserted into the corresponding conveying cylinder 4, and the corresponding conveying cylinder 4 is connected for feeding or cleaning.

[0029] In this example, four conveying cylinders 4 are provided, wherein three cleaning frames 9 correspond to the three conveying cylinders 4 , and one feeding tube 8 corresponds to the remaining conveying cylinder 4 .

The drainage frame 15 is located at the bottom end of the outer shell 1, and the mounting plate 5 is located at the top end of the outer shell 1. A plurality of connecting pipes 14 are fixedly installed at the bottom end of the outer shell 1, and a sealing ring is fixedly installed at the bottom end of the connecting pipe 14, and the connecting pipes 14 correspond to the corresponding connecting holes and the notch 16 respectively.

[0034] It should be noted that a sealing ring is provided to seal the connection between the connecting pipe 14 and the connecting hole, and a notch 16 is provided so that when discharging materials, the materials are discharged from the notch 16. A drainage pipe is provided on the outer wall of the drainage frame 15 to discharge the cleaned sewage, and the sewage from the cleaning conveying cylinder 4 flows into the drainage frame 15. By providing the drainage frame 15, the discharge of sewage is facilitated.

[0035] In this example, the housing 1 is fixedly mounted on the top of the inner wall of the internal mixer feeding port 17 by means of bolts.

[0036] Working principle: When using the internal mixer feeding device, the motor 3 rotates synchronously in the same direction, driving the mounting plate 5 and the drainage frame 15 to rotate synchronously in the same direction. The cylinder 6 can drive the connecting ring 7 to rise and fall, thereby driving the cleaning frame 9 and the feeding pipe 8 to rise and fall. When the mounting plate 5 and the drainage frame 15 rotate, the cylinder 6 drives the cleaning frame 9 and the feeding pipe 8 to rise. When the rotation adjustment is completed, the cylinder 6 drives the cleaning frame 9 and the feeding pipe 8 to descend, so that one end of the cleaning frame 9 and the feeding pipe 8 is stuck in the corresponding conveying cylinder 4, and the corresponding conveying cylinder 4 is connected for feeding or cleaning.
