Description
Technical Field
[0001] The utility model belongs to the technical field of plastic processing, and in particular relates to a leak-proof plastic particle feeding device. Background Art
[0002] Plastic particles are widely used and can be used to make various plastic products.
[0003] Plastic particles need to be strictly screened when they are fed. They are usually screened by a vibrating screening machine. Multiple layers of screens are set up during screening. The mesh of the upper layer is larger than that of the lower layer. The screens are tilted. After the plastic particles fall from the top layer of the screen, they roll downward under the vibration of the screen. Particles with a diameter larger than the mesh remain in the corresponding layer, and particles with a diameter smaller than the mesh fall from the mesh. Then particles of different sizes flow out from the corresponding outlets to meet the feeding requirements of the corresponding particle size.
[0004] When the screen is tilted and accompanied by vibration, when the particles roll down at a faster speed, they are easily driven by other particles and flow directly to the outlet without being screened, resulting in leakage, which is not conducive to accurate feeding and processing. Utility Model Content
[0005] The utility model provides a leak-proof plastic particle feeding device. By setting a blocking belt, the particles are blocked and rolled multiple times by the blocking belt while rolling downward, thereby preventing the particles from being accelerated out by other particles and facilitating full contact with the sieve plate for screening, so as to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leak-proof plastic particle feeding device, comprising a base, a feeding box is mounted on the base, and three inclined sieve plates are mounted inside the feeding box, namely the first sieve plate, the second sieve plate and the third sieve plate; the first sieve plate and the second sieve plate are respectively covered with first material holes and second material holes, and the diameter of the first material hole is larger than the diameter of the second material hole; the third sieve plate is a straight plate without holes; a sealing cover is provided on the feeding box, and a feeding funnel is mounted on the sealing cover, and the feeding funnel is located above the high point of the inclined sieve plate; spaced barrier strips are fixed on the surfaces of the first sieve plate and the second sieve plate; a vibrator is mounted on the bottom of the feeding box; and a discharge port and a discharge nozzle are respectively provided at the lower part of the inclined sieve plate of the feeding box.

A lower limit column is provided on the top of the support leg. The diameter of the lower limit column is smaller than the diameter of the support leg. The bottom surface of the loading box is provided with an upper limit column opposite to the lower limit column. The spring is installed between the lower limit column and the upper limit column.

[0011] Preferably, a plurality of mounting plates are provided on the front and rear of the bottom surface of the sieve plate, and mounting holes are provided on the mounting plates, which are fixed by screws outside the feeding box body.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

According to the required particle diameter, the material is loaded. For example, if particles with a smaller diameter than the first material hole 6 and a larger diameter than the second material hole 7 are selected, they can be added from the discharge nozzle 13 corresponding to the second sieve plate 4. During this period, the vibrator 11 will drive the sieve plate to vibrate, which is conducive to the downward rolling and dispersion of the plastic particles, thereby facilitating the particles to fall to the corresponding sieve plate before rolling to the discharge port 12. Due to the provision of the blocking belt 10, the particles are facilitated to roll downward while being blocked and tumbled multiple times by the blocking belt 10, thereby preventing the particles from being accelerated out by other particles without fully contacting the sieve plate for screening.
[0023] Specifically, the base 1 includes a bottom plate 14, support legs 15 and a spring 16. The support legs 15 are arranged at the four corners of the top surface of the bottom plate 14. A lower limit column 17 is provided on the top of the support leg 15. The diameter of the lower limit column 17 is smaller than the diameter of the support leg 15. The bottom surface of the feeding box 2 is provided with an upper limit column 18 opposite to the lower limit column 17. The spring 16 is installed between the lower limit column 17 and the upper limit column 18; in this embodiment, when the vibrator 11 drives the feeding box 2 to vibrate, the feeding box 2 has sufficient space to vibrate under the action of the spring 16, and the lower limit column 17 cooperates with the upper limit column 18 to prevent the spring 16 from detaching. When the feeding box 2 vibrates, the spring 16 prevents the bottom plate 14 from being interfered with and continues to support stably.
[0024] Specifically, the cross-section of the barrier strip 10 is triangular; in this embodiment, while providing a certain degree of resistance to the plastic particles, it also facilitates their continued downward rolling.
[0025] Specifically, a cavity 19 is provided inside the barrier belt 10, and a row of multiple micropores 20 are provided on the surface of the barrier belt 10 facing the upper part of the inclined screen plate, and a joint 21 connected to the rear end of the barrier belt 10 is provided on the outside of the loading box 2; in this embodiment, the micropores 20 are provided, and an external blowing device can be connected through the joint 21 for intermittent blowing, which further facilitates the full dispersion and screening of the particles when blowing through the micropores 20.
[0026] Specifically, the micropores 20 are close to the sieve plate; in this embodiment, particles are prevented from remaining at the connection between the blocking belt 10 and the sieve plate, and are allowed to fully flow out.
[0027] Specifically, a plurality of mounting plates 22 are provided on the front and rear of the bottom of the sieve plate. The mounting plates 22 are provided with mounting holes and are fixed by screws outside the feeding box 2. In this embodiment, the sieve plate can be conveniently assembled and disassembled by detachable screws.
[0028] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.
[0029] Working principle: During processing, plastic particles are added to the first sieve plate 3 in the feeding box 2 through the feeding funnel 9. When the vibrator 11 drives the feeding box 2 and the first sieve plate 3, the second sieve plate 4, and the third sieve plate 5 therein to vibrate, particles with a diameter larger than the first material hole 6 will remain on the first sieve plate 3, particles with a diameter smaller than the first material hole 6 and a diameter larger than the second material hole 7 will remain on the second sieve plate 4, and particles with a diameter smaller than the second material hole 7 will fall from the second material hole 7 onto the third sieve plate 5, and finally flow out from the corresponding discharge port 12 and discharge nozzle 13. According to the required particle diameter, the material is loaded. For example, if the particles with a diameter smaller than the first material hole 6 and a diameter larger than the second material hole 7 are selected, the material can be added from the discharge nozzle 13 corresponding to the second sieve plate 4. During this period, the vibrator 11 will drive the screen plate to vibrate, which is conducive to the downward rolling and dispersion of the plastic particles, so that they are conducive to falling onto the corresponding screen plate before rolling to the discharge port 12. Due to the provision of the barrier strip 10, while the particles are conducive to rolling downward, they are repeatedly blocked by the barrier strip 10 to prevent the particles from being accelerated out by other particles, which is conducive to full contact with the screen plate for screening. At the same time, micro-pores 20 are provided, which can be connected to an external blowing device through the connector 21 for intermittent blowing. When blowing, the micro-pores 20 further facilitate the full dispersion and screening of the particles, while also preventing the particles from remaining at the connection between the barrier strip 10 and the screen plate, so as to achieve full outflow.
