The injection molding machine body 1 is the prior art, and the specific model can be selected according to actual needs, so the description is not provided herein.
The working principle is as follows: when the device is used by a worker, the plastic raw material to be melted is poured into the feeding bin 3 and falls into the top end of the receiving plate 24 when entering the feeding bin 3, so as to apply downward force to the receiving plate 24, because the rolling sleeve 23 is movably connected with the inner wall of the feeding bin 3 through the rotating shaft, the receiving plate 24 is forced to overturn downwards at this time, so that the plastic raw material on the receiving plate 24 falls into the top end of the first inserting plate 29 and passes through the first screening holes 30 and the second screening holes 33 to enter the inside of the injection bin 2, when the material receiving plate 24 is in a rotating state as the feeding is continued, the cleaning teeth 25 are in contact with the first insert plate 29, so as to clean the plastic raw material with larger particles on the first inserting plate 29 which can not pass through the first material sieving hole 30 to the material distributing groove 26, discharge and collect the plastic raw material into the material receiving bin 27, the plastic material in the receiving bin 27 can be discharged from the discharging pipe 28 by screwing a valve on the discharging pipe 28.
During the use accessible twists adjusting screw 35, because adjusting screw 35 and 34 screw-thread fit of thread groove, consequently drive second picture peg 32 and move to the left in third cavity 31 when adjusting screw 35 atress anticlockwise rotation, make first sieve material hole 30 and second picture peg 32 overlap through this kind of mode, can adjust the clearance in first sieve material hole 30 to adjust the diameter that first sieve material hole 30 sieved plastics raw materials.
When the feeding screw 36 rotates in the injection bin 2 to convey the plastic raw material, the first sliding block 4 is in rolling fit with the first sliding groove 5, so that the feeding screw 36 is fixedly connected with the injection bin 2, and the stability of the feeding screw 36 in the rotation of the injection bin 2 is improved.
When the size in 19 apertures of injection bin outlet is adjusted to the needs, thereby when adjusting and spraying raw materials volume, through stirring the blade on the arc sealing plate 20, because arc sealing plate 20 passes through damping pivot and injection head 8 swing joint, consequently when the staff stirs arc sealing plate 20, make the damping pivot rotate, thereby make arc sealing plate 20 move about on injection head 8, when arc sealing plate 20 activity is to a certain position, arc sealing plate 20 overlaps and blocks it with injection bin outlet 19, thereby adjust the aperture of injection bin outlet 19.
When the gas generated in the melting process of the plastic raw material in the injection bin 2 reaches a certain degree, the sealing block 214 is pushed to compress and deform the second compression spring 213, and at this time, the sealing block 214 is no longer sealed with the second cavity 212 in a blocking manner, so that the gas in the injection bin 2 enters the pressure relief pipe 211 through the second cavity 212 and is discharged outwards through the pressure relief exhaust pipe 215.
By pressing the push rod 16, the movable push block 17 drives the extension spring 18 to be stretched and deformed and move upwards in the limit groove 14, when the movable push block 17 moves to a certain position, the movable push block 17 is in contact with the limit inserted rod 13, when the movable push block 17 continues to be pressed, the movable push block 17 drives the limit inserted rod 13 to extrude the first compression spring 12 and contract inwards, so that the bottom end of the limit inserted rod 13 is no longer connected with the limit groove 14 for limiting, the injection head 8 can be pulled outwards by holding the injection head 8, so that the injection head 8 is detached from the injection bin 2, when the injection head is installed, the second slide block 7 on the injection head 8 is inserted in alignment with the second slide groove 6 on the injection bin 2, when the injection bin is inserted, the left side of the injection bin 2 extrudes the limit inserted rod 13, because the right side of the limit inserted rod 13 is arc-shaped, the right side of the limit inserted rod 13 is stressed to extrude the first compression spring 12 and contract inwards, when the injection, the elastic force generated by resetting drives the limit inserted rod 13 to be inserted into the limit groove 14, and at the moment, the limit inserted rod 13 and the limit groove 14 are limited mutually, so that the injection head 8 and the injection bin 2 are installed.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
