Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and indicated in the drawings can be arranged and designed in various different configurations.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0021] The utility model discloses a kind of mixed hopper with noise reduction structure for plastic particle processing mainly applied to the scene that mixed hopper relies on single spiral structure, it is easy to cause particle to form laminar flow in hopper, thereby affect mixing effect.
[0022] Reference Figure 1 , Figure 2 And Figure 4The utility model provides a kind of mixing hopper with noise reduction structure for plastic particle processing, including hopper base body 1, guide plate 2 and the base body 3 being set on the bottom outer wall of hopper base body 1, further include: mixing mechanism: the bottom inner wall of hopper base body 1 is provided with rotating shaft 9 by bearing, the circumferential outer wall of rotating shaft 9 is provided with dragon blade 14, the circumferential outer wall of rotating shaft 9 close to guide plate 2 is provided with dispersion plate 12 and four stirring rods 11, the top outer wall of dispersion plate 12 is opened with scallop, the circumferential inner wall of hopper base body 1 is provided with sieve plate 10, and sieve plate 10 is opened with a plurality of sieve holes on the top outer wall;Noise reduction mechanism: noise reduction mechanism is set on the top outer wall of base body 3.
[0023] Guide plate 2 is set on the top outer wall of hopper base body 1, and valve 15 is set on the bottom inner wall of hopper base body 1.
[0024] Wherein, guide plate 2 is arranged on the top outer wall of hopper base body 1, which facilitates the smooth introduction of raw materials into the hopper, and the valve 15 arranged on the bottom inner wall of the hopper base body 1 is used for discharging, which facilitates the control of the discharging amount and timing. In actual application, a sealing cover can be arranged on the top of the guide plate 2, which can effectively block dust and impurities from entering the hopper when the equipment is idle or the feeding is intermittent, ensuring the purity of the plastic particles, reducing the noise transmission, further improving the noise reduction effect, and preventing the raw materials in the hopper base body 1 from being damp and oxidized, thereby ensuring the quality of the raw materials.
[0025] In the specific embodiment, after the raw materials are poured, they are first subjected to horizontal stirring by the stirring rods 11 for pretreatment, and then are dispersed by the dispersion plate 12. The dispersion plate 12 cooperates with the scallop to uniformly disperse the particles coming from the conveying to all directions, increasing the dispersion area. The pretreated raw materials are then introduced into the bottom through the sieve holes and are further mixed by the dragon blade 14. The raw materials are stirred from multiple dimensions, so that the plastic particles at different positions can be fully contacted, greatly improving the mixing efficiency and quality.
[0026] Referring to Figure 1 And Figure 4 In a preferred embodiment, the stirring rod 11 has an arc structure.
[0027] In particular, when the arc-shaped stirring rod 11 rotates, it can cover a larger hopper space and touch the inner wall and the center particles due to its unique shape, reducing the mixing dead angle and greatly improving the uniformity of the plastic particle mixing. The arc design can guide the flow of particles. When rotating, the tangential force is generated on the arc surface, so that the particles are not only stirred in the horizontal direction, but also flow longitudinally under the guidance of the arc, forming a three-dimensional mixing flow pattern, which makes the mixing effect better and provides better mixing guarantee for plastic particle processing.
[0028] Referring to Figure 2In a preferred embodiment, the end of the rotating shaft 9 is externally connected with the motor 13. In practical application, the device adopts the noise reduction motor 13 to reduce the noise from the source, create a more quiet and comfortable working environment for the operator, and reduce the damage of noise to the hearing and physical and mental health of the employees.
[0029] With reference to Figure 2 , Figure 3 and Figure 5 In a preferred embodiment, the noise reduction mechanism includes a sound insulation layer 16 arranged inside the hopper wall of the hopper base body 1, four support columns 5 arranged on the top outer wall of the base body 3, a fixing sleeve 6 arranged at one end of the support column 5, and a shock pad 7 arranged on the inner wall of the base body 3, the inner wall of the fixing sleeve 6, and one side of the outer wall of the support column 5.
[0030] Specifically, the sound insulation layer 16 is arranged inside the hopper wall of the hopper base body 1, which can effectively block the noise generated when the plastic particles are mixed from spreading outward, reduce the noise intensity from the source, create a quiet working environment for the operator, reduce the interference to the surrounding environment and personnel, increase the fixing area between the base body 3 and the hopper base body 1 by adding the fixing column and the fixing sleeve 6, improve the stability of the device, and set the shock pad 7 between the two, which can absorb and disperse the vibration energy when the device is running, reduce the influence of vibration on the device and the surrounding structure, reduce the noise caused by vibration, further optimize the noise reduction effect, prolong the service life of the device, and reduce the maintenance cost of the enterprise.
[0031] With reference to Figure 1 and Figure 3 In a preferred embodiment, four support feet 4 are arranged on the bottom outer wall of the base body 3, a non-slip pad 8 is arranged on the bottom outer wall of the support foot 4, and a tooth pattern is formed on the bottom outer wall of the non-slip pad 8.
[0032] Especially, the four support feet 4 can make the mixing hopper placed stably and provide a stable foundation for the operation of the device. The non-slip pad 8 at the bottom of the support foot 4 can increase the friction with the placement surface to prevent the device from sliding due to vibration during operation and ensure the stability of the device. The tooth pattern formed on the bottom of the non-slip pad 8 further improves the anti-skid performance, so that the device can be stable on various ground conditions, effectively avoid damage caused by movement and shaking of the device, and ensure safe and efficient production.
[0033] With reference to Figure 5 In a preferred embodiment, the sound insulation layer 16 adopts a porous structure.
[0034] It should be noted that the sound insulation layer 16 adopts a porous structure and is made of glass wool, and a large number of interconnected micro-pores inside it can reflect, refract and rub the noise sound waves, convert sound energy into heat energy consumption, reduce noise intensity, create a quiet working environment, and also absorb and disperse equipment vibration energy, reduce the impact on the equipment, reduce additional noise, and prolong the service life of the equipment.
[0035] Working principle: when in use, the plastic particles to be mixed are poured from the guide plate 2 into the hopper base body 1, the motor 13 is started to drive the rotating shaft 9 to rotate, and then drive the dragon blade 14, the dispersion plate 12 and the four stirring rods 11 to work. After the raw materials enter the hopper base body 1, the four arc-shaped stirring rods 11 perform transverse stirring on the raw materials to achieve pretreatment. Then, the dispersion plate 12 cooperates with the fan-shaped port to uniformly disperse the incoming particles in all directions, increase the dispersion area, and then the pre-mixed raw materials enter the bottom through the sieve holes on the sieve plate 10. After that, the dragon blade 14 further mixes the raw materials entering the bottom. In the mixing process, the sound insulation layer 16 inside the hopper base body 1 can effectively block the noise generated by the plastic particles during mixing from spreading outward. The shock pad 7 between the base body 3 and the hopper base body 1 can absorb and disperse vibration energy when the device is running and generate vibration, thereby reducing the noise caused by vibration. When the mixing is completed, the valve 15 on the inner wall of the bottom of the hopper base body 1 is opened to discharge the mixed plastic particles.
[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. The replacement can be a partial structure, device, method step replacement, or a complete technical solution. According to the technical scheme and the utility model concept of the present application, equivalent replacement or change should be covered within the protection scope of the present application.
