[0020] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] A crushing and feeding device for injection molding of an acoustic housing comprises a housing 1, wherein the housing 1 is provided with a cylindrical temporary storage chamber 2 located at the top and a cylindrical crushing chamber 3 arranged horizontally at the bottom, wherein the temporary storage chamber 2 and the crushing chamber 3 are connected by a connecting pipe 4, and an operating chamber 5 is provided in the housing 1 between the temporary storage chamber 2 and the crushing chamber 3, wherein a knocking mechanism 6 is provided in the operating chamber 5;

[0022] A circular hole 7 is provided at the top of the temporary storage chamber 2, wherein a cover plate 8 for sealing the circular hole 7 is provided above the circular hole 7, and the cover plate 8 is driven by an electric push rod 27, and a cylinder 9 passing through the circular hole 7 is provided at the bottom of the cover plate 8, wherein a circular plate 10 is provided in the cylinder 9, and the circular plate 10 is driven by a motor I11, and multiple groups of crushing components 12 are axially provided at the bottom edge of the circular plate 10, wherein the bottoms of the multiple groups of crushing components 12 are connected by a bracket 13, and a rotating shaft 14 connected to the bracket 13 is provided at the bottom of the circular plate 10, and a rolling bearing 15 is provided at the bottom of the rotating shaft 14, wherein a clamping block 16 is provided on the outer sleeve of the rolling bearing 15, and a clamping ring 17 for fixing the clamping block 16 is provided in the top opening of the connecting pipe 4.

[0023] like Figure 1 、 3 As shown, a circle of arc grooves 18 are correspondingly provided on the inner wall of the cylinder 9 and the outer wall of the circular plate 10, wherein two groups of arc grooves 18 form a group of sliding channels with a circular cross section, and multiple groups of balls 19 are arranged in parallel in the sliding channels.

[0024] The circular plate 10 is prevented from sliding up and down in the cylinder 9 by the ball bearing 19 clamping the arc groove 18. At the same time, when the cylinder 9 is driven by the motor I11 to rotate, it will also drive the ball bearing 19 to rotate in the arc groove 18 to reduce the resistance it encounters during rotation. The upper half of the rotating shaft 14 is fixed by the cylinder 9 and the circular plate 10, and the lower half of the rotating shaft 14 is fixed by the connecting pipe 4, the retaining ring 17, the block 16 and the rolling bearing 15, so as to achieve the purpose of improving its stability and preventing it from swinging. In addition, the upper and lower ends of the crushing assembly 12 can be indirectly fixed through the bracket 13 to prevent it from being unstable and easy to bend when crushing the material.

[0025] In this embodiment, a recessed portion 20 for accommodating the electric push rod 27 is recessed downward on the cover plate 8 , wherein a feed pipe 23 is also provided on the cover plate 8 .

[0026] In this embodiment, the snap ring 17 is fixed in the connecting tube 4. The cross-section of the internal opening of the snap ring 17 is polygonal, and the size of the clamping block 16 is adapted to the size of the internal opening of the snap ring 17. When the rotating shaft 14 rotates in the rolling bearing 15, the snap ring 17 fixes the clamping block 16 and thus the outer ring of the rolling bearing 15, preventing the clamping block 16 from rotating together with the rolling bearing 15 and the rotating shaft 14.

[0027] In this embodiment, a crushing mechanism 22 is provided in the crushing chamber 3 , wherein a discharge pipe 23 is provided at the bottom of the crushing chamber 3 .

[0028] In this embodiment, a feed channel 24 is provided at the top of the crushing chamber 3, communicating with the bottom end of the connecting pipe 4. The feed channel 24 is arranged at an angle. Material flowing down the connecting pipe 4 flows through the feed channel 24 to the feed opening at the top of the crushing chamber 3, preventing the crushing mechanism 22 from pulverizing the material in the crushing chamber 3 and splashing into the connecting pipe 4.

[0029] In this embodiment, the striking mechanism 6 comprises a rotating shaft driven by a motor II, to which a striking ball 602 is fixed via a connecting rod 601, resting against a side wall of the operating chamber 5. The side wall of the operating chamber 5 is also provided with an inlet and outlet sealed by a switch door. During operation, the motor II drives the rotating shaft, which, via the connecting rod 601, drives the striking ball 602 to strike the upper and lower walls of the operating chamber 5. This vibrates the bottom wall of the temporary storage chamber 2, the top wall of the feed channel 24, and the top wall of the crushing chamber 3, preventing material from adhering to the shaft and hindering its flow or otherwise affecting the crushing effect.

[0030] In this embodiment, a circular ring 25 with a height of no more than 1 cm is provided at the bottom of the temporary storage chamber 2 , wherein scraping portions are provided obliquely at both ends of the circular ring 25 , and a cross bar 26 fixedly connected to the inner wall of the circular ring 25 is radially provided on the rotating shaft 14 .

[0031] The method of use of the present invention: Figure 1 As shown, the connecting pipe 4 is sealed by the retaining ring 17, the retaining block 16, the rolling bearing 15 and the rotating shaft 14 to prevent the material in the temporary storage chamber 2 from flowing into the crushing chamber 3 without human intervention. The motor I11 drives the crushing assembly 12 to rotate by driving the circular plate 10, thereby performing primary crushing on the material in the temporary storage chamber 2 to prevent it from agglomerating into blocks. During the above process, the circular plate 10 also drives the rotating shaft 14 to rotate in the rolling bearing 15 to prevent it from interfering with the normal rotation of the rotating shaft 15 and the circular plate 10.

[0032] When the material in the temporary storage chamber 2 needs to be processed in the bottom crushing chamber 3, the electric push rod 27 drives the cover plate 8 to drive the cylinder 9 to move upward in the circular hole 7, and also drives the rolling bearing 15 and the clamping block 16 to slide upward from the clamping ring 17 through the circular plate 10 and the rotating shaft 14, so that the material in the temporary storage chamber 2 can flow into the inner diameter feeding channel 24 of the connecting pipe 4 and flow into the crushing chamber 3 for re-crushing. At this time, the distance between the clamping block 16 and the opening of the clamping ring 17 can be adjusted or it can be slid into the opening of the clamping ring 17 to achieve the purpose of controlling the feed amount of the crushing chamber 3. In the above process, the rotating shaft 14 will also drive the ring 25 to move up and down, so as to scrape off the material inside the temporary storage chamber 2 to prevent it from adhering and affecting subsequent processing work.

[0033] In the present invention, the distance between the clamping block 16 and the opening of the clamping ring 17 is adjusted or the clamping block 16 is slid into the opening of the clamping ring 17 to achieve the purpose of controlling the feed amount of the crushing chamber 3. At the same time, the material is initially crushed by the crushing component 12 in the temporary storage chamber 2, and then the material is crushed again by the crushing mechanism 22 in the crushing chamber 3 to prevent the material from clumping and affecting its subsequent introduction into the injection molding equipment, or affecting the injection molding work of the subsequent injection molding equipment.

[0034] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
