Its core function is to ensure the efficiency of the production process and the consistency of product quality.

[0003] While existing plastic feeding devices can effectively remove dust and impurities from the surface of plastic granules, the failure to synchronize dust removal and material conveying processes means that the device can only convey clean granules to the next process after dust removal is completed. This intermittent working mode severely disrupts the continuity of the production process, not only reducing production efficiency but also creating a capacity bottleneck, failing to meet the process requirements of modern plastic processing for continuous and automated production. Utility Model Content

[0018] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0019] Example 1: like Figs. 1-3 As shown, this utility model provides a plastic production feeding device, including a support platform 1 and a housing 2 disposed on the support platform 1. The housing 2 has a receiving space, and the receiving space of the housing 2 contains plastic granules. It also includes: Fixed plate 3, there are several fixed plates 3, several fixed plates 3 are set in the housing 2, and each of the several fixed plates 3 is provided with a material dropping hole 4; Rotary table 5, there are several rotating tables 5, several rotating tables 5 are respectively set on several fixed plates 3, and each of the several rotating tables 5 is provided with a discharge hole 6 that matches the discharge hole 4 on the several fixed plates 3. The dust removal component is mounted on the support platform 1. The output end of the dust removal component is connected to the housing 2. The dust removal component is used to remove dust from the plastic particles inside the housing 2. The drive assembly is mounted on the housing 2. The output end of the drive assembly is connected to several rotating tables 5. The drive assembly drives the several rotating tables 5 to rotate along the upper surface of several fixed plates 3, so as to control the alternating and intermittent cooperation between the material discharge holes 4 on the fixed plates 3 and the material discharge holes 6 on the rotating tables 5 to limit the falling speed of the plastic particles.

[0020] During use, plastic granules are fed into the receiving space of the housing 2. At this time, the discharge hole 4 on the fixed plate 3 and the discharge hole 6 on the rotating table 5 are misaligned, and the granules are temporarily blocked above the fixed plate 3. The drive component is started, which drives the rotating tables 5 of each layer to start rotating. When the discharge hole 6 of the rotating table 5 is aligned with the discharge hole 4 of the fixed plate 3, the plastic granules will fall from the hole. During the falling process, the dust removal component continuously introduces clean airflow into the device to blow away the dust on the surface of the granules. As the rotating table 5 continues to rotate, the hole is misaligned again, and the feeding stops. This cycle repeats, realizing intermittent but continuously controllable feeding. The whole process ensures both the uniformity of feeding and the dust removal effect, realizing efficient and continuous production operation.

[0021] Example 2: like Figs. 1-3 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, several fixing plates 3 are fixedly installed on the inner sidewall of the housing 2, dividing the accommodating space inside the housing 2 into three equal parts. The fixing plates 3 are arranged parallel to each other, and grooves 7 are formed on the upper surface of each fixing plate 3. After the plastic granules enter the device, they first fall onto the uppermost fixing plate 3. When the rotating table 5 rotates to align the discharge hole 6 with the discharge hole 4 of the fixing plate 3, the granules will fall from the hole. The fixing plates 3 are arranged vertically along the inner wall of the device, realizing the layer-by-layer segmented discharge of the granules.

[0022] Furthermore, the size and shape of several rotating platforms 5 are adapted to the grooves 7 on several fixed plates 3, and the upper surfaces of several rotating platforms 5 are flush with the upper surfaces of several fixed plates 3, and the several rotating platforms 5 are slidably connected to the grooves 7 on several fixed plates 3. When the motor 14 drives the rotating platforms 5 to rotate, the two holes will periodically align with the material discharge holes 4 on the fixed plates 3, controlling the falling of plastic granules. The material flow rate is controlled by the alternating opening and closing of the two material discharge holes 6.

[0023] Furthermore, the dust removal assembly includes a blower 8 and an exhaust fan 9. Several ventilation holes 10 are provided on the two opposite side walls of the housing 2 in the vertical direction. Ventilation chambers 11 are fixedly installed on the two opposite side walls of the housing 2. The ventilation holes 10 on the two opposite side walls of the housing 2 are respectively located in the two ventilation chambers 11. The blower 8 and the exhaust fan 9 are both fixedly installed on the support platform 1 and are respectively located on both sides of the housing 2. The output end of the blower 8 is connected to a blower pipe 12, which is connected to one of the ventilation chambers 11. The output end of the exhaust fan 9 is connected to an exhaust pipe 13, which is connected to the other ventilation chamber 11. When blower 8 is started, a powerful airflow is forced into the left ventilation chamber 11 through blower pipe 12. The airflow is sprayed into the feeding device from the ventilation hole 10 on the left side of the device, blowing up the dust on the surface of the plastic particles. At the same time, exhaust fan 9 continuously draws air from the right ventilation chamber 11 through exhaust pipe 13, forming a stable airflow channel inside the device. The air containing dust is sucked out from the right ventilation hole 10. Dust removal is completed during the falling process of the plastic particles. The exhaust fan 9 used in this paper is connected to a dust filter collection device to facilitate the collection of dust drawn out by the exhaust fan 9. The connection between the filter collection device and the exhaust fan 9 is existing technology and will not be described here.

[0024] Furthermore, the drive assembly includes a motor 14, which is fixedly mounted on the top surface of the housing 2. A drive shaft 15 is fixedly mounted on the output end of the motor 14, passing through the top surface of the housing 2. The drive shaft 15 is fixedly connected to several rotating platforms 5 inside the housing 2, and rotatably connected to several fixed plates 3 inside the housing 2. When the motor 14 is started, it drives the drive shaft 15, which runs through the entire device, to rotate. Since the drive shaft 15 is connected to the rotating platforms 5, the operation of the motor 14 simultaneously drives all the rotating platforms 5 to rotate synchronously on the fixed plates 3, ensuring that the rotating platforms 5 on each layer operate in a coordinated manner.

[0025] Furthermore, several cleaning brushes 16 are fixedly mounted vertically on the outer side of the drive shaft 15. These cleaning brushes 16 correspond to several rotating tables 5 and are located above each of the rotating tables 5. When the motor 14 drives the drive shaft 15 to rotate, these brushes will rotate along with it. Utilizing the rotational power of the drive shaft 15 itself, without the need for additional energy, it can prevent plastic particles from accumulating or blocking the vent holes 10, ensuring smooth feeding and making the entire production process stable and reliable.

[0026] Furthermore, the length of several cleaning brushes 16 is equal to the diameter of several rotating platforms 5. When the drive shaft 15 drives the cleaning brushes 16 to rotate, the bristles can cover the entire surface of the rotating platform 5, sweeping all the way to the ventilation holes 10 on both sides of the feeding device, effectively preventing plastic particles from accumulating on the rotating platform 5, and continuously cleaning the area around the ventilation holes 10 to avoid particle blockage affecting the dust removal effect. At the same time, the self-cleaning is achieved by utilizing the rotational power of the drive shaft 15 itself, without the need for additional energy consumption.

[0027] Furthermore, two inlets 17 are provided on the top wall of the housing 2. Plastic granules are fed simultaneously through the two inlets 17 at the top. The two inlets 17 evenly distribute the material inside the device, avoiding the accumulation and blockage that can easily be caused by single-point feeding, and improving the overall feeding efficiency.

[0028] Furthermore, a hopper 18 is fixedly installed at the bottom of the housing 2. The conical design of the hopper 18 allows the material to be automatically concentrated at the outlet position, making it convenient to directly connect to the feed port of the next process.

[0029] The working principle of a plastic production feeding device disclosed in this application is as follows: In use, after the plastic granules are fed into the housing 2, they first fall onto the top fixed plate 3. At this time, the discharge hole 4 of the fixed plate 3 and the discharge hole 6 of the rotating table 5 are misaligned, and the granules are temporarily blocked. The motor 14 starts and drives the drive shaft 15 to rotate, so that each layer of rotating table 5 slides in the groove 7 of the fixed plate 3. When the discharge hole 6 of the rotating table 5 and the discharge hole 4 of the fixed plate 3 are aligned, the granules will fall layer by layer. During the falling process, the blower 8 blows airflow from the ventilation chamber 11 on one side to blow up the dust on the surface of the granules. At the same time, the exhaust fan 9 on the other side draws away the dust-laden air through the ventilation chamber 11, completing the dust removal. As the rotating table 5 continues to rotate, the holes are misaligned again and the feeding stops. By controlling the rotation speed of the rotating table 5, the feeding speed is adjusted. The entire device achieves controllable intermittent feeding through the alternating cooperation of multiple layers of fixed plates 3 and rotating tables 5, and can also complete the dust removal during the falling process, ensuring the uniformity, continuity and cleanliness of the feeding.

[0030] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
