[0007] The feeding mechanism includes a cylinder, a square column, a spiral strip, a round rod, a semi-circular block, a cuboid, a protrusion, a long column, a protruding rod, a screen plate, a buffer plate, and a pressure block. The square column is slidably installed in the first chute. One side of the cylinder is fixedly installed on the top of the square column. The cuboid is fixedly installed on the top of the cylinder.

One side of the round rod is rotatably installed at the bottom of the square column. The buffer plate is fixedly installed on the right side of the inner wall of the feed pipe. The pressure block is fixedly installed on the inner wall of the feed pipe. When the round rod moves, it drives the square column to move. When the square column moves, it drives the cylinder to move. When the cylinder moves, it drives the cuboid to move. When the cuboid moves, it drives the protrusion to move.

[0008] According to the above technical solution, the protrusion contacts the protruding rod, and the semicircular block contacts the transmission device. When the transmission device is started, it will drive the semicircular block to move up and down repeatedly.

[0009] According to the above technical solution, the spiral strip is fixedly installed on the circumferential surface of the round rod, and the semicircular block is fixedly installed on the other side of the round rod. When the round rod moves, it will drive the spiral strip to move. When the spiral strip moves, it will rotate due to the pressure block.

[0010] According to the above technical solution, the screening mechanism includes a connecting plate, a column plate, a triangular prism, small blocks, a door panel, a collection box, a gear, a flexible fan plate, and a rotating shaft. The connecting plate is fixedly installed at the right end of the square column, and the column plate is fixedly installed at the top of the front and rear ends of the connecting plate. The triangular prism is rotatably installed on the side of the column plate close to the cylindrical column, and one side of the small block is fixedly installed on the side of the column plate away from the cylindrical column. The door panel is fixedly installed on the other side of the small block. The collection box is slidably installed on the right side of the feed pipe, and the rotating shaft is rotatably installed on the inner wall of the feed pipe. When the column plate moves, it drives the triangular prism to move. When the triangular prism moves, it drives the gear to rotate. When the gear rotates, it drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the flexible fan plate to rotate.

[0011] According to the above technical solution, the triangular prism meshes with the gear, and the flexible fan plate contacts the sieve plate. When the triangular prism moves downward, it will drive the gear to rotate; when the triangular prism rises, it cannot drive the gear to rotate.

[0012] According to the above technical solution, the gear is fixedly installed on the circumferential surface of the rotating shaft, and the flexible fan plate is fixedly installed on the circumferential surface of the rotating shaft. When the flexible fan plate rotates, it will throw the accumulated material back towards the direction of the round rod, and perform secondary screening on the accumulated material.

[0013] According to the above technical solution, the heat insulation mechanism includes a square plate, a telescopic plate, a triangular prism, a baffle, a sliding plate, a round-headed column, a long plate, a square column, a push plate, and a heat insulation plate. The triangular prism is fixedly installed on the inner wall of the feed pipe, the sliding plate is fixedly installed on the bottom of the triangular prism, the baffle is rotatably installed on the bottom of the triangular prism, the heat insulation plate is rotatably installed on the side of the sliding plate near the round rod, the square plate is fixedly installed on the circumferential surface of the round rod, the telescopic plate is fixedly installed on the bottom of the square plate, the round-headed column is slidably installed on the inner wall of the feed pipe, one side of the long plate is fixedly installed on the side of the round-headed column away from the round rod, one end of the square column is fixedly installed on the other side of the long plate, and the push plate is fixedly installed on the other end of the square column. When the telescopic plate moves, it will press the baffle below the triangular prism downwards, and when the baffle moves, it will push the round-headed column towards the side near the feed pipe.

[0014] According to the above technical solution, the push plate is in contact with the heat insulation plate, and the telescopic plate is in contact with the baffle. When the push plate moves downward, it will drive the heat insulation plate to move downward, pouring the internal material into the lower part.

[0015] A method of using a feeding device for plastic hot cutting production includes the following steps:

[0016] Step 1: Pour the material into the feed pipe. The material will flow from the buffer plate to the screen plate. When the conveyor rotates, it will drive the semi-circular block to move. When the semi-circular block moves, it will drive the round rod to move. When the round rod moves, it will drive the spiral to move. The spiral will rotate under the pressure of the pressure block. When the round rod moves, it will drive the protrusion to move. When the protrusion contacts the protrusion rod, it will generate vibration, causing the screen plate to vibrate.

[0017] Step 2: When the column moves, it will drive the triangular prism and the small block to move. When the triangular prism moves, it will drive the gear to move. When the gear moves, it will drive the flexible fan plate to move. When the small block moves, it will drive the door panel to open and close repeatedly.

[0018] Step 3: When the round rod moves, it will cause the square plate to move. When the square plate moves, it will cause the baffle to open and close. When the baffle opens and closes, it will cause the round head column to move. When the round head column moves, it will cause the heat insulation plate to open and close.

[0019] This invention provides a feeding device for plastic hot-cutting production. It has the following advantages:

[0020] (1) In this invention, when the round rod moves upward, it will drive the spiral to move. When the spiral contacts the pressure block, it will cause the spiral to rotate. This can prevent blockage caused by excessive material flow and increase manual working time. When the square column moves, it will drive the round column to move. When the round column moves, it will drive the cuboid to move. When the cuboid moves, it will drive the protrusion to move. The protrusion will contact the semicircular block to generate vibration, which will increase the screening effect on the material above. At the same time, it can prevent the material above from blocking the screen plate and affecting the screening process.

[0021] (2) In this invention, when the column plate moves upward, it will drive the small piece to move, and when the small piece moves, it will drive the door plate to move, which can prevent the accumulation of defective materials on the screen plate and affect the screening of materials on the screen plate. When the column plate moves, it will drive the triangular column to move, and when the triangular column moves, it will drive the gear to move. However, when the gear moves, it will drive the soft fan plate to move, which can perform secondary screening of the materials after the first screening. At the same time, it can avoid the inability to effectively screen the usable materials to the bottom when there is too much material, thus avoiding material waste.

[0022] (3) In this invention, when the round rod moves, it will drive the square plate to move. When the square plate moves, it will drive the baffle to move. When the baffle is opened, the material will continue to fall. This can control the feeding rate of the material and prevent the material feeding rate from affecting the conveying device below. When the round column moves, it will drive the long plate to move. When the long plate moves, it will drive the square column to move. When the long column moves, it will drive the heat insulation plate to move. This can effectively block the heat below and prevent the heat below from being dispersed to the feed pipe and affecting the material that has not fallen. It can also effectively prevent the heat below from being wasted and affecting the work below. Attached Figure Description

[0040] The push plate 509 contacts the heat insulation plate 510, and the telescopic plate 502 contacts the baffle 504. When the push plate 509 moves downward, it will drive the heat insulation plate 510 to move downward, pouring the internal material into the lower part.

[0041] A method of using a feeding device for plastic hot cutting production includes the following steps:

[0042] Step 1: Pour the material into the feed pipe 3. The material will flow onto the screen plate 310 on the buffer plate 311. When the conveying device 2 rotates, it will drive the semi-circular block 305 to move. When the semi-circular block 305 moves, it will drive the round rod 304 to move. When the round rod 304 moves, it will drive the spiral strip 303 to move. The spiral strip 303 will rotate under the pressure of the pressure block 312. When the round rod 304 moves, it will drive the protrusion 307 to move. When the protrusion 307 contacts the protrusion rod 309, it will generate vibration, causing the screen plate 310 to vibrate.

[0043] Step 2: When the column plate 402 moves, it will drive the triangular column 403 and the small block 404 to move. When the triangular column 403 moves, it will drive the gear 407 to move.

[0045] During operation: The transmission device 2 in pipe 1 is activated. When the transmission device 2 is activated, it moves the semi-circular block 305. When the semi-circular block 305 moves, it moves the circular rod 304. When the circular rod 304 moves, it moves the spiral strip 303. When the spiral strip 303 moves, it rotates due to the pressure of the pressure block 312. When the circular rod 304 moves, it moves the square column 302. When the square column 302 moves, it moves the circular column 301. When the circular column 301 moves… When the material moves, it will cause the cuboid 306 to move. When the cuboid 306 moves, it will cause the protrusion 307 to move. When the protrusion 307 moves, it will contact the protrusion 309 on the column 308 and generate vibration. When the column 308 vibrates, it will cause the screen plate 310 to vibrate. When the material enters the feed pipe 3, it will fall onto the buffer plate 311. When the material falls from the buffer plate 311, it will enter the screen plate 310. When the material vibrates, the defective material will be screened out.

[0046] When the square column 302 moves, it drives the connecting plate 401 to move. When the connecting plate 401 moves, it drives the column plate 402 to move. When the column plate 402 moves, it drives the triangular column 403 to move. When the triangular column 403 moves, it drives the gear 407 to rotate. When the gear 407 rotates, it drives the rotating shaft 409 to rotate. When the rotating shaft 409 rotates, it drives the flexible fan plate 408 to rotate. When the flexible fan plate 408 rotates, it throws the accumulated material away from the triangular column 403 for secondary screening. When the column plate 402 moves, it drives the small piece 404 to move. When the small piece 404 moves, it drives the door plate 405 to move. When the door plate 405 moves, it opens the seal on the collection box 406. When the seal on the collection box 406 is released, the screened defective material will enter the collection box 406.

[0047] When the material falls above the baffle 504, the movement of the round rod 304 will cause the square plate 501 to move. When the square plate 501 moves, it will cause the telescopic plate 502 to move. When the telescopic plate 502 moves, it will press the baffle 504 below the triangular prism 503 downward. When the baffle 504 moves, it will push the round head column 506 towards the side closer to the feed pipe 3. When the round head column 506 moves, it will cause the long plate 507 to move. When the long plate 507 moves, it will cause the square column 508 to move. When the square column 508 moves, it will cause the push plate 509 to move. When the push plate 509 moves, it will cause the heat insulation plate 510 on the slide plate 505 to move. When the heat insulation plate 510 opens, it will pour the internal material into the conveying device 2 below.

Step 2: When the column plate (402) moves, it will drive the triangular column (403) and the small block (404) to move. When the triangular column (403) moves, it will drive the gear (407) to move. When the gear (407) moves, it will drive the flexible fan plate (408) to move. When the small block (404) moves, it will drive the door plate (405) to open and close repeatedly. Step 3: When the round rod (304) moves, it will drive the square plate (501) to move. When the square plate (501) moves, it will drive the baffle (504) to open and close. When the baffle (504) opens and closes, it will drive the round head column (506) to move. When the round head column (506) moves, it will drive the heat insulation plate (510) to open and close.
