[0002] In the production process of plastic woven cloth, finished yarns of various properties and colors are used for weaving; in the processing of finished yarns, plastic particles of different materials are melted and drawn. The particles need to be mixed in a certain proportion first, and then the mixed particles are melted and drawn, and finally the finished yarns are woven.
[0003] In the related art, when particles of different materials are mixed, the required various plastic particles are usually manually poured into a mixing tank in packages, and then transferred to a wire drawing machine for wire drawing after manual stirring or drum mixing, and finally processed into finished wire.
[0004] However, since the plastic particles are added in packages, the addition ratio of the plastic particles cannot be well controlled. A large difference in the ratio of plastic particles may lead to large differences in the physical and mechanical properties of the finished silk, and also cause the color and luster of the finished silk to be uneven, resulting in the finished silk being inconsistent with the required finished silk, which in turn makes the subsequent production of high-end plastic woven cloth The qualified rate is low, and the scrap rate is relatively high in the subsequent lamination and color printing processing.

[0009] An adjustment component is provided on the outside of the metering bucket, and the adjustment component includes a power member and an adjustment block. A plug hole is provided on the outer side of the metering bucket for the adjustment block to be inserted and moved.

After the internal space of the quantitative hopper is filled with plastic particles, the first solenoid valve and the upper solenoid valve are controlled to close, and the lower solenoid valve is opened, so that the plastic particles in the quantitative hopper are injected into the mixing barrel in proportion, and the plastic particles in the mixing barrel are mixed by the stirring component.
[0011] By adopting the above technical scheme, when mixing plastic particles of different proportions, the volume size of the metering hopper is first adjusted through the power parts and the adjustment block according to the proportion of different particles, and then the plastic particles of various materials are respectively injected into the corresponding feed hopper, and the staff controls the first solenoid valve and the upper solenoid valve to open, and closes the lower solenoid valve at the same time, so that the particles inside the feed hopper are injected into the metering hopper from the upper opening of the metering hopper. After the metering hopper is filled with plastic particles, the first solenoid valve and the upper solenoid valve are controlled to be closed, and the lower solenoid valve is opened at the same time, so that the plastic particles inside the metering hopper are injected into the mixing barrel from the lower opening of the metering hopper in a certain proportion, and finally the stirring component is started to stir the plastic particles inside the mixing barrel evenly, and finally the storage is completed through the storage box, and the discharging component completes the discharging; through the coordinated setting of the feed hopper and the metering hopper, the mixing ratio of different types of particles is more accurate, and the color and quality of the processed finished silk are improved.

[0015] By adopting the above technical scheme, the plastic particles discharged from the lower side of the metering hopper first fall into the diffusion mixing disk. As the diffusion mixing disk rotates, the plastic particles on the diffusion mixing disk diffuse to the edge and fall into the gathering mixing disk. The gathering mixing disk rotates synchronously with the diffusion mixing disk, so that the particles falling on the gathering mixing disk fall into the mixing barrel through the discharge hole. Through the coordinated arrangement of the diffusion mixing disk and the gathering mixing disk, different types of particles can be mixed more evenly.
[0016] Optionally, the diameter of the diffusion mixing disk is smaller than the diameter of the gathering mixing disk, and a blocking plate is provided on the upper edge of the gathering mixing disk, and the upper edge of the blocking plate is higher than the lower edge of the diffusion mixing disk.
[0017] By adopting the above technical scheme, during the operation of the diffusion mixing disk and the gathering mixing disk, the possibility of particles on the diffusion mixing disk not being able to smoothly fall onto the gathering mixing disk is reduced through the setting of the baffle, so that the particles on the diffusion mixing disk fall into the gathering mixing disk as much as possible, thereby reducing the loss of different particles during mixing.
[0018] Optionally, a diffusion spiral baffle is provided on the upper side of the diffusion mixing disk, and a gathering spiral baffle is installed on the upper side of the gathering mixing disk.
[0019] By adopting the above technical solution and setting the diffusion spiral baffle and the gathering spiral baffle, the time of particles on the diffusion mixing disk and the gathering mixing disk is prolonged, so that the particles can have more time to mix, further enhancing the mixing effect of the plastic particles.
[0020] Optionally, an opening and a second control valve for controlling the opening is provided at the lower portion of the mixing barrel, and an injection port is provided on the upper side of the material storage box and is located directly below the lower opening of the mixing barrel.
[0021] By adopting the above technical solution and setting the second control valve, the stirring time of the plastic particles inside the mixing barrel can be better controlled. After a certain period of stirring, the second control valve is controlled to open, and the evenly mixed particles inside the mixing barrel are injected from the injection port into the storage box for storage.

[0025] By adopting the above technical solution, during the assembly process of the metering hopper and the feed hopper, the installation stability of the feed hopper and the metering hopper is enhanced by setting the mounting frame and the mounting plate, thereby avoiding the possibility of loose assembly of the feed hopper and the metering hopper during the process.
[0026] Optionally, the power component is an adjusting motor, which is fixedly mounted on the lower side of a mounting plate for fixing the metering bucket. The output shaft of the adjusting motor is connected to a screw. The part of the adjusting block located on the outer side of the metering bucket is fixedly provided with an adjusting plate. The adjusting plate is provided with a screw hole that cooperates with the screw thread. The adjusting block abuts against the lower side of the mounting plate for fixing the metering bucket.
[0027] By adopting the above technical solution, since different plastic particles correspond to different proportions and quantities, the adjustment ratio of the corresponding plastic particles is controlled by adjusting the volume inside the metering bucket; starting the adjustment motor drives the screw to rotate, and drives the adjustment plate to move along the axial direction of the screw, so as to control the volume of the adjustment block inside the metering bucket, so as to better adjust the volume inside the metering bucket.
[0028] Optionally, the mixing method includes the following steps: S1: loading, first injecting plastic particles of different materials into the corresponding feed hopper. S2: batching, controlling the first solenoid valve and the upper solenoid valve to open, and the lower solenoid valve to close, so that the particles inside the feed hopper are injected into the quantitative hopper through the feed port, until the quantitative hopper is filled with plastic particles, and then controlling the first solenoid valve and the upper solenoid valve to close. S3: preliminary mixing, controlling the lower solenoid valve to open, so that the plastic particles in the quantitative hopper fall into the upper side of the diffusion mixing disk, and are scattered along the diffusion spiral baffle to the edge of the diffusion mixing disk, and then the plastic particles fall from the edge of the diffusion mixing disk to the upper side of the gathering mixing disk. During the rotation of the gathering mixing disk, the plastic particles on the gathering mixing disk gather to the middle and flow into the mixing barrel through the discharge hole. S4: mixing again, the rotating shaft drives the stirring blade inside the mixing barrel to rotate, so that the mixing particles falling into the mixing barrel are further mixed. S5: Material storage.

[0031] 1. Through the coordinated setting of the quantitative bucket and the adjustment component, the mixing ratio of different types of particles can be more accurately achieved, thus improving the color and quality of the finished silk.
[0032] 2. Through the coordinated setting of the diffusion mixing disk and the gathering mixing disk, the plastic particles discharged from the lower side of the metering hopper first fall into the diffusion mixing disk.
