It has excellent physical and mechanical properties, chemical stability, electrical insulation, and heat resistance, as well as good optical and barrier properties, so it is widely used in packaging, printing, electronics, construction, and other fields. Raw material mixing is an important part of the PET film production process. During the mixing process of raw materials, mixing devices are usually used. These devices have different structures and functions, but the common goal is to achieve uniform mixing of raw materials. For example, a common raw material mixing device for PET film processing includes a support frame, a drive component box, a mixing box, and a stirring mechanism. Among them, the stirring mechanism is the core component of the mixing device, which uniformly mixes the raw materials through rotation and stirring.

[0004] In the prior art, when mixing granular PET film processing raw materials, the raw materials cannot be fully mixed, the mixing time is long, and the efficiency is low. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model aims to provide a raw material mixing device for PET film processing to solve the technical problems in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A raw material mixing device for PET film processing includes a support frame, a drive component box at one end of the inner wall of the support frame, a mixing box at the other end of the inner wall of the support frame and on one side of the drive component box, a mixing cavity is provided in the inner wall of the mixing box, and a stirring mechanism is provided in the mixing cavity.

[0008] The stirring mechanism is composed of a driving rotor, multiple connecting rods at both ends of the driving rotor, a first mixing component that is slidably connected to the inner wall of the mixing tank at one end of the connecting rod, and a second mixing component located on the outer wall of the driving rotor and on one side of the connecting rod.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example

[0024] like Figs. 1 to 3 As shown, a raw material mixing device for PET film processing includes a support frame 11, a drive component box 12 at one end of the inner wall of the support frame 11, a mixing box 13 at the other end of the inner wall of the support frame 11 and located on one side of the drive component box 12, a mixing cavity 14 provided on the inner wall of the mixing box 13, and a stirring mechanism 20 provided in the mixing cavity 14.

[0025] The stirring mechanism 20 is composed of a driving rod 21, multiple connecting rods 22 at both ends of the driving rod 21, a first mixing component 23 with one end of the connecting rod 22 slidably connected to the inner wall of the mixing box 13, and a second mixing component 24 on the outer wall of the driving rod 21 and located on one side of the connecting rod 22.

[0026] It should be noted that, in this embodiment, the support frame 11 serves as the support structure for the entire device. One end of its inner wall is provided with a drive component box 12 for mounting power components such as drive motors. The other end of the inner wall of the support frame 11, located on one side of the drive component box 12, is provided with a mixing chamber 13. The mixing chamber 13 has a mixing cavity 14 inside for containing and mixing the raw materials required for PET film processing.

[0027] The stirring mechanism 20 is the core component of the mixing device, and it is located inside the mixing chamber 14. The stirring mechanism 20 mainly consists of a drive rod 21, a connecting support rod 22, a first mixing component 23, and a second mixing component 24. One end of the drive rod 21 is rotatably connected to the inner wall of one end of the mixing chamber 13, and the other end passes through the inner wall of the other end of the mixing chamber 13 and is connected to the actuator end of the drive motor located inside the drive component housing 12. In this way, the drive motor can drive the stirring mechanism 20 to rotate via the drive rod 21.

[0028] The bottom of the mixing chamber 13 is provided with a discharge door 131, which is hinged to the bottom of the mixing chamber 13. One side of the discharge door 131 is a discharge port 132, which is connected to the inside of the mixing chamber 14.

[0029] One end of the drive rod 21 is rotatably connected to the inner wall of one end of the mixing chamber 13, and the other end of the drive rod 21 passes through the inner wall of the other end of the mixing chamber 13 and is connected to the actuator end of the drive motor provided in the drive component box 12.

[0030] The other end of the connecting rod 22 is connected to the inner wall of the first hybrid component 23, and the connecting rods 22 are arranged in a ring to drive the two ends of the outer wall of the rotating rod 21.

[0031] The first mixing component 23 is cylindrical in shape, and its outer wall is provided with multiple circular through holes 231. These through holes can increase the mixing effect of the raw materials.

[0032] The second mixing component 24 includes a mixing connecting rod 241 connected to the outer wall of the drive rotating rod 21, and a stirring blade 242 at one end of the mixing connecting rod 241. Based on the stirring blade 242 of the second mixing component 24, the number of blades is increased and the blade shape is optimized, such as using spiral or arc blades, to improve mixing efficiency and mixing uniformity.

[0033] The stirring blade 242 is tilted. The tilted setting of the stirring blade 242 can generate a stronger stirring force when rotating, further improving the mixing effect of the raw materials.

[0034] The top of the mixing chamber 13 is also provided with a feed inlet 133, which is connected to the inside of the mixing chamber 14.

[0035] The working principle of this utility model is as follows:

[0036] In this device, the raw material enters the mixing chamber 14 through the feed port 133 at the top of the mixing box 13. The design of the feed port ensures that the raw material can enter the mixing chamber smoothly, while preventing excessive dust or splashing during the feeding process.

[0037] The drive motor starts, driving the stirring mechanism 20 to rotate via the drive rod 21. The connecting support rod 22 rotates with the drive rod 21, simultaneously driving the first mixing component 23 to rotate within the mixing chamber 14. The cylindrical design and circular through-holes 231 on the outer wall of the first mixing component 23 facilitate the mixing and dispersion of the raw materials. The stirring blades 242 of the second mixing component 24 are inclined, generating a stronger stirring force during rotation, further promoting the mixing of the raw materials. The inclination angle and number of the stirring blades 242 are carefully designed to ensure optimal mixing results. Under the action of the stirring mechanism 20, the raw materials are continuously subjected to shearing, convection, and diffusion within the mixing chamber 14, thereby achieving uniform mixing. During the mixing process, the speed of the drive motor and the structural parameters of the stirring mechanism 20 can be adjusted as needed to achieve the best mixing effect.

[0038] Once the raw materials are evenly mixed, turn off the drive motor to stop the rotation of the stirring mechanism 20. Open the discharge door 131 at the bottom of the mixing chamber 13, and the mixed raw materials are discharged through the discharge port 132. The design of the discharge door 131 ensures that the raw materials can be discharged smoothly while preventing excessive dust or leakage during the discharge process. After discharge is completed, close the discharge door 131 and prepare for the next feeding and mixing operation.

[0039] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
