Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5This utility model provides an embodiment of a novel PA66 slicing and sieving device, comprising a sieving box 1, wherein the sieving box 1 is provided with a sieving chamber 101 and a storage tank 102, and a sieve plate 9 is provided inside the sieving chamber 101, and the sieve plate 9 is inclined. The sieve plate 9 includes a sieve mesh 901 and side plates 902. Two side plates 902 are provided, and the two side plates 902 are symmetrically fixedly installed on both sides of the sieve mesh 901. Each side plate 902 has an insertion groove 9021 on its lower end surface. The side plate 902 has a plate groove 9022 along one side of the insertion groove 9021, and the plate groove 9022 communicates with the insertion groove 9021. The width of the insertion groove 9021 is greater than the overall width of the insert plate 18 plus the limiting plate 19. Pad blocks 11 are symmetrically provided on both sides below the sieve plate 9. The upper surface of the screen plate is inclined, and the angle of the inclined surface matches the inclination angle of the screen plate, so that the screen plate can fit and contact the pad 11. The two pads 11 correspond to the positions of the two insertion slots 9021 respectively. An insert plate 18 is fixedly installed on the top of the pad 11, and a limiting plate 19 is fixedly installed on one side of the insert plate 18. When installing the screen plate, the insertion slot 9021 of the screen plate 9 is aligned with the insert plate 18 and the limiting plate 19. Then, the screen plate 9 is held down and the insert plate 18 and the limiting plate 19 are inserted into the insertion slot 9021. Then, the screen plate 9 is released. Under the action of gravity, the screen plate 9 will tilt to the left and move downward on the pad 11. At this time, the limiting plate 19 is inserted into the plate groove 9022, so that the screen plate 9 is stably installed. A sealing groove 103 is provided on the front end face of the screening box 1, and a sealing cover 5 is provided inside the sealing groove 103.

[0025] When the screen plate needs maintenance and cleaning, the cover 5 is removed, and the screen plate 9 is tilted to the upper right to move it so that the limiting plate 19 is disengaged from the plate groove 9022. Then the screen plate 9 can be removed from the pad 11 and taken out of the screening box 1 through the cover groove 103. The overall operation is simple and convenient, and no tools are required, which increases the convenience of removing the screen plate 9 and is conducive to the maintenance and cleaning of the screen plate 9.

[0026] Furthermore, a square frame 12 is fixedly installed below the pad 11, and a vibration motor 14 is fixedly installed inside the square frame 12. A compression spring 16 is fixedly installed below the square frame 12, and the lower end of the compression spring 16 is fixedly connected to the screening box 1. During the screening of PA66 new slices, by starting the vibration motor 14 and under the action of the compression spring 16, the screen plate 9 can be shaken, which facilitates the spread of PA66 new slices falling on the screen plate 9, which is beneficial to the screening of PA66 new slices.

[0027] Furthermore, an upper sleeve 15 is fixedly installed below the frame 12 along the outer side of the compression spring 16. A lower sleeve 17 is fitted on the outer side of the upper sleeve 15, and the lower end of the lower sleeve 17 is fixedly connected to the screening box 1. A baffle 13 is provided on one side of the frame 12, and the baffle 13 is fixedly connected to the screening box 1. The inner side of the lower sleeve 17 is in contact with the outer side of the upper sleeve 15, so that when the vibrating motor 14 starts and causes the screen plate 9 to shake, the upper sleeve 15 and the lower sleeve 17 can play a limiting and guiding role, causing the screen plate 9 to shake in the up and down direction.

[0028] Furthermore, a discharge square tube 8 is provided on one side of the lowest end of the sieve plate 9, and the discharge square tube 8 is fixedly connected to the screening box 1 and extends to the outside of the screening box 1. The internal width of the discharge square tube 8 is greater than the width of the sieve plate 9. Protective plates 903 are symmetrically fixedly installed on the front and rear ends of the two side plates 902, which can protect and restrict the PA66 new slices falling on the sieve plate 9, prevent the PA66 new slices from falling from the front and rear ends of the sieve plate 9, and increase the stability of PA66 new slice screening.

[0029] Furthermore, a feed pipe 3 is fixedly installed above the screening box 1, and a guide pipe 10 is fixedly installed above the screening chamber 101 of the screening box 1, and the guide pipe 10 is connected to the feed pipe 3. This guide pipe can guide the input of the PA66 new chips, making it easier for the PA66 new chips to fall stably onto the screen plate 9. A dust suction pipe 4 is fixedly installed on one side above the screening box 1. The dust suction pipe 4 is connected to an air extraction device, which facilitates the extraction and treatment of dust floating in the screening process inside the screening box 1, increasing its practicality.

[0030] Furthermore, the front end face of the cover 5 is flush with the front end face of the screening box 1. Stabilizing plates 6 are symmetrically arranged on both sides of the front end of the cover 5, and the stabilizing plates 6 are in contact with the cover 5. The upper end of the stabilizing plate 6 is rotatably connected to the screening box 1 through a pin. The setting of the stabilizing plate 6 can restrict the cover 5 and increase its practicality.

[0031] Furthermore, a support column 2 is fixedly installed at the bottom of the screening box 1, and a sealing door 7 is installed on the front face of the screening box 1 by means of a hinge. The sealing door 7 is positioned corresponding to the storage tank 102, which facilitates the cleaning of the screened debris in the storage tank 102 and increases its practicality.

[0032] Working principle: During use, when screening PA66 new chips, the PA66 new chips are added into the feed pipe 3 and guided by the guide pipe 10 to fall onto the screen plate 9. At the same time, the vibration motor 14 is started, and under the action of the compression spring 16, the screen plate 9 can shake, which facilitates the spread of the PA66 new chips on the screen plate. Then, the debris in the PA66 new chips falls down, and the PA66 new chips slide to one side along the screen plate 9 and are output through the discharge square pipe 8. When the screen plate 9 needs maintenance and cleaning, the two stabilizing plates 6 can be rotated to move the two stabilizing plates 6 from the front end of the cover 5 to other positions. Then the cover 5 can be removed, and the screen plate 9 can be tilted to the upper right to move the limiting plate 19 out of the plate groove 9022. Then the screen plate 9 can be removed from the pad block 11 and taken out from the screening box 1 through the cover groove 103. This increases the convenience of removing the screen plate 9 and is conducive to the maintenance and cleaning of the screen plate 9.
