[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. In this utility model, the raw material is fed into the metering cylinder through the feed inlet. The metering cylinder receives the raw material and applies force to the pressure sensor after receiving it. Once the set weight is reached, the feeding stops. After the solenoid valve opens, the first motor drives the transmission rod to rotate the screw pusher and feed the material into the mixing box. This achieves quantitative feeding and mixing, resulting in better mixing effect and higher quality after mixing. It also avoids manual weighing and feeding, making the work more efficient.

[0018] 2. In this utility model, the third motor drives the rotating shaft to rotate the second stirring rod, which is installed on the outside and inside in a staggered manner, to mix the raw materials, thereby making the mixing effect better and the quality better;

[0019] Furthermore, the second motor drives the scraper to rotate, which can scrape off any raw materials that may be adhering to the inner wall and discharge them, preventing them from sticking to the inner wall during mixing and affecting subsequent production results. It also saves subsequent cleaning time and makes the work more efficient. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Please see Figure 1 and Figure 2 This utility model provides a mixing device for plastic bag production, including a mixing tank 1 for mixing raw materials inside, achieving proper mixing. Support feet 2 are provided at the bottom of the mixing tank 1 to elevate it and facilitate the installation of a mounting frame 18. A controller 3 is installed on the outside of the mixing tank 1, allowing for convenient operation by the staff. A discharge port 14 is provided at the bottom of the mixing tank 1 to discharge the mixed raw materials. Rotating shafts 16 are symmetrically mounted on both sides of the mixing tank 1 via bearings, and several second stirring rods 17 are staggered between the rotating shafts 16. This mutual stirring during mixing enhances the mixing effect and improves work efficiency. The rotation speed is faster. A drive mechanism is installed at the bottom of the rotating shaft 16 to make it rotate. The drive mechanism includes a driving wheel 19 and a driven wheel 110 respectively located at the bottom of the rotating shaft 16. The driving wheel 19 and the driven wheel 110 are connected by a belt 111. A mounting frame 18 is provided at the bottom of the mixing box 1. The mounting frame 18 is easy to open to replace the internal parts. A third motor 112 is installed inside the mounting frame 18 and connected to a rotating shaft 16. When the third motor 112 is working, the driving wheel 19 and the driven wheel 110 at the bottom of the rotating shaft 16 rotate under the action of the belt 111, so that the rotating shaft 16 can drive the second stirring rod 17 at the top to stir the internal raw materials.

[0028] Please see Figure 2 and Figure 3A metering cylinder 4 is installed at the top of the mixing tank 1 to receive and weigh the raw materials. Two metering cylinders 4 can be installed to speed up the process. A feed inlet 5 is located on one side of the top of the metering cylinder 4 to facilitate the input of raw materials for weighing. A groove is recessed on the top surface of the mixing tank 1 to connect with the metering cylinder 4, improving its stability when it is inside the groove and reducing shaking through a snap-fit ​​mechanism. A pressure sensor 10 is installed inside the groove to weigh the metering cylinder 4, facilitating quantitative weighing before unloading and avoiding the slow efficiency of manual weighing. A funnel-shaped discharge pipe 8 extends from the bottom of the metering cylinder 4 through the top of the mixing tank 1. The funnel shape facilitates downward discharge, increasing efficiency during discharge. An internal solenoid valve 9 is installed, which facilitates the user's operation of feeding, allowing the material to be discharged after quantitative weighing. A transmission rod 11 is fixedly installed inside the quantitative cylinder 4 via bearings. A spiral push rod 13 is connected to the bottom end of the transmission rod 11 and is located inside the feeding pipe 8. The spiral push rod 13 rotates downward to discharge material, preventing blockage. A first motor 6 is installed at the top of the quantitative cylinder 4 and connected to the transmission rod 11. After weighing, the solenoid valve 9 opens, and the first motor 6 drives the transmission rod 11 to rotate, causing the internal spiral push rod 13 to rotate and discharge material, making the feeding faster and more automated. Several first stirring rods 12 are installed on the outside of the transmission rod 11 inside the quantitative cylinder 4. The first stirring rods 12 enhance the crushing effect of the raw materials during the stirring process, reduce agglomeration, and improve the mixing effect.

[0029] Please see Figure 2 and Figure 4 The mixing box 1 is equipped with a U-shaped scraper 15 that fits against its inner wall, resulting in better scraping effect. The top protruding rod of the scraper 15 is connected to the mixing box 1 via a bearing. A second motor 7 is installed at the top of the mixing box 1, and the output end of the second motor 7 is connected to the protruding rod of the scraper 15. When the second motor 7 drives the scraper 15 to rotate, the scraper 15 scrapes the inner wall of the mixing box 1, thereby scraping away the raw materials attached to the inner wall and preventing the raw materials from adhering to the inner wall, which would make subsequent cleaning inconvenient and improve work efficiency.

[0030] Working principle: In use, first connect the first motor 6, the second motor 7, the solenoid valve 9, the pressure sensor 10, the third motor 112, and the controller 3, and connect them to an external power supply. Then, feed the raw material into the metering cylinder 4 through the feed port 5. After feeding, the weight of the metering cylinder 4 is weighed under the pressure of the pressure sensor 10 at the bottom. After reaching the set value, the feeding stops, and the solenoid valve 9 is opened. This allows the first motor 6 to drive the transmission rod 11, which in turn drives the screw pusher 13 to feed the raw material into the mixing box 1. Then, the third motor 112 drives the rotating shaft 16 to rotate through the drive wheel 19, the driven wheel 110, and the belt 111. The rotating shaft 16 drives the second stirring rod 17 to rotate, which stirs the raw material inside the mixing box 1. After stirring, the raw material can be discharged through the discharge port 14. Moreover, the second motor 7 drives the scraper 15 to rotate, which can scrape the inner wall and speed up the discharge rate, thus completing the work.
