Description

Technical Field

[0001] This utility model relates to the field of film processing technology, and in particular to a feeding device for a film extrusion equipment. Background Technology

[0002] Patent document CN220443696U discloses a feeding mechanism for a casting machine, relating to the technical field of casting machine devices. It includes: a support frame, a mixing tank inside the support frame, a sealing cap on the top of the mixing tank, a three-way pipe connected to the bottom of the mixing tank, a mixing component located on one side of the mixing tank, and a material control component located on one side of the three-way pipe. The mixing component ensures uniform mixing of the raw materials. Raw materials at the bottom of the mixing tank flow from the feed pipe into the lifting pipe. A first drive motor drives an auger to lift the raw materials from the bottom of the mixing tank into the discharge pipe, and then back into the mixing tank. Multiple mixing processes ensure thorough mixing of the various raw materials. Furthermore, the material control component controls the outflow of raw materials, preventing excessive material from entering the casting machine, which could lead to sedimentation, overflow of excessive material, and incomplete melting of the raw materials, resulting in particulate protrusions on the cast film.

[0003] However, the feeding device still relies on manual feeding, which is inefficient for mass production. Furthermore, during the process of heating and extruding the raw material through the extrusion equipment to the film head, the terrain and frame design result in a long conveying pipe distance, causing the raw material to gradually cool down and reducing its quality, thus leading to a decline in film quality. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

The conveying component is connected to the heating component and conveys the raw material. The heat preservation component is sleeved on the conveying component and prevents the temperature of the raw material in the conveying component from dropping.

[0046] In this embodiment, the raw material mixing assembly includes a mixing tank 110, a mixing motor 120, mixing blades 130, and a control valve 140. The mixing tank is located on one side of the frame and has a mixing chamber. The bottom of the mixing tank has a discharge section 111, and the top of the mixing tank has an exhaust pipe 112. The mixing motor is located at the top of the mixing tank, with its rotating end facing the mixing chamber of the mixing tank. The rotating end of the mixing motor is rotatably located in the mixing tank. The mixing blades are rotatably located in the mixing tank, and their tops are connected to the mixing motor. The mixing blades mix the raw materials in the mixing tank. The control valve is located at the bottom of the mixing tank and controls the opening and closing of the discharge section of the mixing tank.

[0047] In this embodiment, the feeding assembly includes a vacuum feeder 210 and a suction pipe 220. The vacuum feeder is located at the top of the mixing tank, and its outlet is connected to the mixing tank. The vacuum feeder draws the raw materials into the mixing tank. One side of the suction pipe is connected to the inlet of the vacuum feeder, and the suction pipe sucks up the raw materials. This vacuum feeder is existing technology and will not be described in detail here.

[0048] In this embodiment, the drying assembly includes a blower 310, a heating box 320, and an air supply duct 330. The blower is located on one side of the mixing tank, and one side of the heating box is connected to the blower. An electric heating rod is arranged in a circuitous manner in the heating box to heat the cold air. One side of the air supply duct is connected to the heating box, and the other side of the air supply duct is connected to the mixing tank to deliver hot air.

[0049] In this embodiment, the heating component includes an extrusion device 410, which is disposed at the bottom of the mixing tank and heats the raw materials after mixing.

[0050] In this embodiment, the conveying assembly includes a discharge pipe 510, one side of which is connected to the extrusion device, and the heated raw material is conveyed to the extrusion die by the discharge pipe.

[0051] Example 2

[0052] like Figure 1-5 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, the heat preservation component includes a heat preservation cover 610 and an electric heating wire 620. The heat preservation cover is connected to the frame and is fitted onto the discharge pipe.

[0054] The working principle of this utility model:

[0055] During operation, the suction pipe is placed into the hopper, and the vacuum feeder is activated, drawing the raw material into the mixing tank through the suction pipe. Once a single raw material has been drawn, the suction pipe is placed into another hopper. After the material is drawn, the blower delivers cold air to the heating chamber, where electric heating rods heat the cold air. The heated air is then delivered to the mixing tank to preheat and dry the raw material. The mixing motor drives the mixing blades to rotate, thus mixing the raw material. Once mixing is complete, the control valve opens the discharge section, transferring the raw material to the extrusion device. The extrusion device heats the raw material, and the melted material is then conveyed through the discharge pipe to the die head. During this conveying process, electric heating wires continuously heat the raw material in the discharge pipe to prevent its temperature from dropping.
