Description

Technical Field

[0001] This utility model belongs to the technical field of stretch film production equipment, specifically, it relates to a mixing device for stretch film raw materials. Background Technology

[0002] In the production process of stretch film, various raw materials need to be mixed in a certain proportion, and the uniformity of the mixing directly affects the quality of the stretch film. Most of the mixing devices currently used have problems such as uneven mixing and low mixing efficiency.

[0003] Application CN220808053U relates to the field of stretch film production equipment technology and discloses a raw material mixing mechanism for stretch film production. The mechanism includes a mounting base, a mixing tank fixedly mounted inside the mounting base, a drive motor mounted on the top of the mixing tank, and a mixing shaft fixedly connected to the output shaft of the drive motor. The end of the mixing shaft extends into the interior of the mixing tank and is fixedly connected to multiple stirring rods. A mixing assembly is disposed between two adjacent stirring rods, and the mixing assembly includes a fixed sleeve rotatably mounted on the outside of the mixing shaft. In use, the drive motor is started to rotate the mixing shaft, which in turn rotates the stirring rods and the mixing shaft, thereby achieving mixing of the raw materials in different directions. This improves the efficiency of raw material mixing while ensuring the mixing effect.

[0004] However, the aforementioned patent also has the following problems: During the raw material addition process, the device only has one set of feed inlets. In stretch film production, it is usually necessary to mix multiple different types of raw materials in specific proportions, and the single feed inlet design cannot meet the needs of rapid filling. In actual operation, multiple raw materials can only be added to the device sequentially for mixing. This batch-by-batch addition method is time-consuming, increases the labor intensity and operating time of workers, and reduces production efficiency. Due to the limited internal space of the mixing tank, the next batch of raw materials can only be added and mixed after the mixing of one batch is completed. This further limits the processing efficiency of the device, making it unable to meet the requirements of large-scale, continuous production, and causing inconvenience in the use of the device.

[0005] In view of this, this utility model is proposed. Utility Model Content

Since the second guide hopper 33 is connected to the third guide pipe 24 through the fourth guide pipe 25, the material can enter the third guide pipe 24 through the fourth guide pipe 25. The first feed pump 31 is started, and the material is conveyed to the inside of the first guide hopper 26 through the first feed pipe 32. The material in the first guide hopper 26 also enters the connected third guide pipe 24. The third feed pump 37 is started, and the material is added to the inside of the third guide hopper 36 through the third feed pipe 38 and the second feed pipe 35. Then, it is conveyed to the inside of the mixing tank 20 through the third guide hopper 36. The first servo motor 11 is started, and its output shaft drives the first rotating shaft 13 to rotate through the coupling. Both the first rotating shaft 13 and the second rotating shaft 14 are equipped with pulleys 15 on their outer walls. A transmission belt 16 is sleeved between the two sets of pulleys 15.

One end of the second rotating shaft 14 is fixedly connected to the auger 19. The rotation of the second rotating shaft 14 drives the auger 19 to rotate inside the first guide tube 18. The third guide pipe 24 is fixedly connected to the second guide pipe 22 via the connecting flange 23. The second guide pipe 22 is connected to the first guide pipe 18. The auger 19 rotates to transport the material in the third guide pipe 24 through the first guide pipe 18 to the inside of the mixing box 20. The second servo motor 28 is started, and its output shaft drives the third rotating shaft 29 to rotate via the coupling. A stirring plate 30 is fixedly installed on the outer wall of the third rotating shaft 29.
