[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figures 1-3 , Figure 5 and Figure 6The technical solution shown is a closed metering and filling device for PET plastic granules. To solve the problem of inconvenient collection after PET plastic granules scatter, the device discloses: a machine body 1 and a cylinder 2 installed on the upper part of the machine body 1. A closing door 9 is rotatably installed at the front end of the machine body 1. A feed inlet 3 is installed at an angle on the upper end of the cylinder 2. An electronic valve 8 is installed on the upper end of the machine body 1, and the upper end of the electronic valve 8 is connected to the interior of the cylinder 2. A filling box 14 is provided inside the machine body 1, and a closed metering and filling mechanism is provided at the lower end of the filling box 14. The closed metering and filling mechanism collects the PET plastic granules. The closed metering and filling mechanism is provided with a collection box 10, and the two sides of the collection box 10 are embedded with… The sleeve is installed at the bottom of the machine body 1. The machine body 1 has a movable frame 11 inside, and sliders 15 are fixedly installed on the left and right sides of the movable frame 11. The two sides of the sliders 15 are slidably connected to the inside of the machine body 1. The movable frame 11 has a tray frame 12 fixedly installed inside, and the upper end of the tray frame 12 is provided with an adhesive anti-slip pad 13. The upper end of the adhesive anti-slip pad 13 is correspondingly bonded to the bottom of the filling box 14. The upper end of the filling box 14 corresponds to the lower end of the electronic valve 8. The machine body 1 has a scraper 16 fixedly installed inside, and the height of the scraper 16 is slightly higher than the upper end of the filling box 14. The rear end of the scraper 16 is inclined and corresponds to the top of the filling box 14.

[0020] When using a closed-loop metering and filling device for PET plastic granules, an appropriate amount of PET plastic granules is added through the feed inlet 3 at the top of the cylinder 2. After addition, the granules are stored. When filling is required, the electronic valve 8 is activated. Activating the electronic valve 8 opens the inside of the cylinder 2, allowing the PET plastic granules inside the cylinder 2 to fall into the filling box 14 for collection. Once the filling box 14 is full of PET plastic granules, the closing door 9 is opened. By pulling the movable frame 11, the sliders 15 on both sides of the movable frame 11 move along... As the machine body 1 slides inside, the movable frame 11 is pulled outward. Inside the movable frame 11, the filling box 14 is supported by the tray frame 12. The tray frame 12 and the filling box 14 are bonded together by the adhesive anti-slip pad 13. As the movable frame 11 is pulled, the filled PET plastic granules come into contact with the scraper 16 and are leveled by the rear end of the scraper 16, so that the PET plastic granules inside the collection box 10 are quantitatively measured and can be filled. The scraped PET plastic granules fall into the collection box 10 after passing through the tray frame 12. The collected PET plastic granules can be put back into the filling.

[0021] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, discloses the following to address the issue of caking affecting subsequent filling: an auxiliary anti-caking mechanism is provided at the upper end of the cylinder 2, which prevents PET plastic particles from clumping. The auxiliary anti-caking mechanism is equipped with a hydraulic rod 4, the middle end of which is fixedly installed at the upper end of the cylinder 2. A lifting chamber 5 is fixedly installed at the output end of the hydraulic rod 4. A drive motor 6 is fixedly installed inside the lifting chamber 5. A stirring rod 7 is fixedly installed at the output end of the drive motor 6, and the stirring rod 7 is rotatably installed at the bottom of the lifting chamber 5.

[0022] After PET plastic granules are filled into the feed inlet 3, they enter the cylinder 2 for storage. By starting the drive motor 6 inside the lifting chamber 5, the drive motor 6 can drive the stirring rod 7. The rotation of the stirring rod 7 can drive the PET plastic granules inside the cylinder 2 to stir and disperse them, preventing the PET plastic granules from clumping and solidifying, which would affect the metering and filling. At the same time, the lifting chamber 5 can drive the stirring rod 7 to adjust its height by starting the hydraulic rod 4. The height can be adjusted while stirring, which further improves the stirring and dispersing effect.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
