Description

Technical Field

[0001] The utility model relates to a PET film production discharging device, belonging to the technical field of PET film production. Background Art

[0002] PET film is a thin film made of polyethylene terephthalate. PET film has good chemical stability and is not easily corroded by acids, alkalis and solvents. PET film is widely used in food packaging, pharmaceutical packaging, electronic product protective film, printing industry and other fields.

[0003] During the production of PET film, different types of raw materials are mixed, then poured into an extruder for extrusion molding, and finally formed through processes such as stretching. However, manual operation is required when mixing the raw materials. Manual operation cannot accurately control the materials, and mixing operations are required after manual weighing, resulting in low overall operating efficiency.

[0004] In order to solve the above problems, corresponding solutions have emerged in the industry, such as the Chinese authorized utility model patent with authorization announcement number CN219788898 U and patent name: A PET film production and discharging device. In the above patent, several material hoppers are provided, and the bottom ends of the material hoppers are equipped with flow electromagnetic valves, and the bottom end surface of the motor box is equipped with a pair of stirring mechanisms. The overall design of this PET film production and discharging device is novel and the structure is simple. It can discharge the PET film raw materials to be produced and can perform mixing operations at the same time, greatly improving the overall production efficiency.

[0005] However, the above patent has the following problems in actual use:

[0006] 1. When the device of the above patent is in use, the material in the hopper will fall onto the conveyor belt. At this time, the material will be spread flat on the conveyor belt and flow or flow. At this time, the material will fall into the gap of the conveyor belt, which will cause equipment failure or inaccurate material quantity. The baffle plate is located between the hopper and the curved plate, and cannot solve the problem that the material will flow when it just falls.

[0007] 2. The stirring mechanism of the above patent cannot stir the materials evenly during stirring. When the materials are transported to the stirring mechanism, due to the gaps between the arc-shaped plates, when the stirring blades start to rotate, the materials will be discharged from the gaps by the stirring blades. The materials are discharged before they are evenly stirred, resulting in the materials not being evenly stirred.

[0008] 3. The above patent cannot prepare multiple mixed materials at the same time when in use. The next mixed material can only be processed after the previous mixed material is processed, resulting in low production efficiency and failure to meet production needs. Summary of the Invention

[0009] The technical problem to be solved by the utility model is: to provide a discharging device for PET film production to solve the problems faced in the industry.

[0010] To solve the above technical problems, the utility model is realized through the following technical solutions: a discharging device for PET film production, including a portal support frame, a circular through hole is arranged at the middle position of the top of the portal support frame, a stirring structure is arranged above the circular through hole, a sealing structure is arranged below the circular through hole, a plurality of raw material hoppers are respectively arranged on both sides of the stirring structure, an internal support plate is arranged below the inner side of the portal support frame, a moving structure is arranged on the internal support plate, and a plurality of mixing hoppers are arranged on the moving structure.

[0011] Preferably, the stirring structure includes a stirring support frame, the stirring support frame is located above the circular through hole, a lifting cylinder is arranged on the stirring support frame, a stirring motor is arranged on the cylinder shaft of the lifting cylinder, and a plurality of stirring rods are arranged on the motor shaft of the stirring motor.

[0012] Preferably, the sealing structure includes a plurality of sealing cylinders installed on the side edges of the bottom of the circular through hole, a sealing pressing plate is arranged on the cylinder shaft of the sealing cylinder, and a circular retaining ring is arranged at the bottom of the sealing pressing plate.

[0013] Preferably, the moving structure includes a plurality of moving electric cylinders installed on the upper surface of the internal support plate and parallel to each other, a plurality of sliders are arranged on the moving electric cylinders, and the mixing hoppers are installed on the sliders.

[0014] Preferably, a middle rectangular through hole is arranged on the internal support plate, and the middle rectangular through hole penetrates from the upper surface to the lower surface of the internal support plate.

[0015] Preferably, electromagnetic flow valves are respectively arranged at the bottoms of the raw material hoppers and the mixing hoppers.

[0016] Compared with the prior art, the beneficial effect of the utility model is: when in use, various raw materials are respectively placed into the raw material hoppers. When different types of mixed materials are needed, the mixing hoppers are driven by the sliders to move to the bottom of the raw material hoppers to receive materials. Receiving materials through the hoppers solves the problem in the prior art that materials will fall into the gaps of the conveyor belt, resulting in equipment failures or inaccurate material quantities.

[0017] After the mixed materials are received, the mixed materials in the mixed materials are fully stirred by the stirring structure, thus solving the problem in the prior art that the materials are discharged before being evenly stirred, resulting in the materials not being evenly stirred.

[0018] In this patent, multiple mixing hoppers are provided to receive materials simultaneously, solving the problem in the prior art that multiple kinds of mixed materials cannot be prepared simultaneously during use, resulting in low production efficiency. Brief Description of the Drawings
