Description

Technical Field

[0001] This utility model relates to the technical field of POE film extrusion equipment, and in particular to a POE film extrusion molding device. Background Technology

[0002] In photovoltaics, electronic packaging, and other fields, POE (polyolefin elastomer) films have become key materials due to their excellent flexibility, weather resistance, and electrical insulation. With the continuous growth of market demand for POE films and the increasing diversification of product specifications and performance requirements, the performance and efficiency of POE film extrusion molding equipment have attracted much attention. Currently, traditional POE film extrusion molding devices have many limitations. Regarding mold replacement, most use complex fixing methods such as bolts, which are not only cumbersome and time-consuming to disassemble and install, affecting production efficiency, but also prone to equipment damage due to frequent operation. In the cutting stage, some equipment lacks cutting precision, making it difficult to accurately control the cutting blade's stroke and cutting timing, resulting in inconsistent film lengths and failing to meet the stringent dimensional accuracy requirements of high-end applications. Manual or inefficient cutting methods further limit the improvement of production efficiency. Regarding cooling systems, some devices have poor cooling effects, failing to cool the film quickly and evenly, leading to instability in the internal molecular structure and crystallinity of the film, affecting key properties such as tensile strength and flexibility. Therefore, we propose a POE film extrusion molding device to solve this problem. Utility Model Content

Pulling the pull plate moves the fixed shaft, fixed plate, and insert block, causing the fixed plate to compress the spring and pull the insert block out of the extrusion die head. This allows for the disassembly of the extrusion die head, facilitating the extrusion production of films of different specifications. A motor drives an eccentric wheel to rotate, which in turn drives a sliding rod to reciprocate linearly within a limit frame via a connecting rod.

Compared to manual cutting or other inefficient cutting methods, this significantly improves film cutting efficiency, accelerates production, and enhances overall production efficiency.

[0012] In this invention, a POE film extrusion molding device is provided, comprising a cooling assembly, drainage plates, and drainage pipes. When the pump is activated, cooling water from the water tank is drawn out through a short pipe, diverted to two side distribution pipes via a connecting pipe, and then sprayed evenly onto the film by spray nozzles at the bottom of the multiple distribution pipes to cool the film. A placement plate is used to receive the cut film, and drainage plates on both sides of the placement plate guide the water generated during film cooling to a drain pipe on one side of the placement box for discharge, preventing water accumulation from affecting film quality and subsequent operations. The multiple spray nozzles can... It can fully cover the surface of the adhesive film, quickly remove the heat from the film, and allow it to solidify and set rapidly. The rapid and uniform cooling can precisely control the molecular structure and crystallinity inside the film, ensuring that key performance indicators such as tensile strength, flexibility, and weather resistance of the film are stable and meet the standards, providing a reliable guarantee for the performance of the film. In addition, the combined design of the drainage plate and drainage pipe can promptly and effectively drain the water generated by cooling the film from the placement box, avoiding water accumulation on the placement plate and working area, preventing the film from getting damp and damaged due to prolonged contact with water, and keeping the film dry and clean.

[0021] In this embodiment, both sides of the extrusion box 2 are provided with placement grooves and sliding grooves.

The insert block 403 is movably inserted into the interior of the corresponding extrusion die head 5, facilitating the installation and removal of the extrusion die head 5. For disassembly and replacement, the eccentric wheel 701 is rotatably mounted on one side of the fixed frame 6, and the auger 3 is rotatably mounted on the inner wall of one side of the extrusion box 2. Motors are fixedly mounted on one side of both the fixed frame 6 and the extrusion box 2. The output shafts of the two sets of motors are fixedly connected to the eccentric wheel 701 and the auger 3, respectively. The cutting blade 704 is located above the placement plate 12. A limit frame 705 is fixedly mounted on one side of the fixed frame 6. The slide rod 703 is slidably mounted inside the limit frame 705 to facilitate the rotation of the auger 3 and the eccentric wheel 701, facilitate the extrusion of the film, and facilitate the reciprocating cutting of the film.

[0022] In this embodiment, a pump body 803 is fixedly installed at the bottom of the short pipe, one end of the pump body 803 is fixedly connected to the connecting pipe 804, the pump body 803 is fixedly installed on the inner wall of the top of the bracket 9, multiple spray heads 806 are located on the right side of the cutting blade 704, the water tank 802 is fixedly installed on the top of the bracket 9, and the top of the water tank 802 is fixedly installed with a water inlet pipe 801 to facilitate cooling of the extruded film, two sets of fixing plates 404 are slidably installed inside the corresponding placement slots, two sets of insert blocks 403 are slidably installed inside the corresponding slide grooves, the two ends of two sets of springs 405 are fixedly connected to the corresponding fixing plates 404 and the inner wall of one side of the placement slot, two sets of guide plates 406 are fixedly installed on one side of each of the two sets of pull plates 401, and the two sets of guide plates 406 are slidably installed inside the two sides of the extrusion box 2 to facilitate stable sliding of the insert blocks 403, drain plates 11 are fixedly installed on both sides of the placement plate 12, and a drain pipe is fixedly installed on one side of the placement box 10 to facilitate the discharge of cooling wastewater.

[0023] In this embodiment, when in use, after the POE raw material is fed into the extrusion box 2 from the feed hopper 1, the motor drives the auger 3 to rotate. The auger 3, through the propulsive action of the spiral blades, conveys the raw material forward along the inside of the extrusion box 2. During the conveying process, the raw material is squeezed, stirred and heated to plasticize it. The plasticized raw material is pushed to the extrusion die head 5. Through the specific shape and size of the extrusion die head 5, a POE film with a specific cross-sectional shape is extruded. When the extrusion die head 5 needs to be replaced, the pull plate 401 is pulled, which drives the fixed shaft 402, the fixed plate 404 and the insert block 403 to move. This causes the fixed plate 404 to squeeze the spring 405, so that the insert block 403 is pulled out from the extrusion die head 5. The extrusion die head 5 can be disassembled, which is convenient for extruding films of different specifications. During installation, by releasing the pull plate 401, the insert block 403 is re-inserted into the replaced extrusion die head 5 under the reset action of the spring 405. The extruded POE film enters the placement box 10. The water tank 802 at the top of the bracket 9 stores cooling water. The water inlet pipe 801 at the top of the water tank 802 can be used to replenish the cooling water. Pump 803 starts, drawing cooling water from water tank 802 through a short pipe. The water is then diverted through connecting pipe 804 to two branch pipes 805 on either side, and sprayed evenly from spray nozzles 806 at the bottom of the branch pipes 805. This cooling process allows the film to solidify quickly, ensuring its quality and performance. The motor drives eccentric wheel 701 to rotate, which in turn drives sliding rod 703 to reciprocate linearly within limit frame 705 via connecting rod 702. The cutting blade 704 at the bottom of sliding rod 703 moves up and down accordingly. Once the film has cooled to a certain temperature, the cutting blade 704 moves downwards, cutting the film. Placement plate 12 receives the cut film. Drainage plates 11 on both sides of placement plate 12 guide water generated during film cooling to a drain pipe on one side of placement box 10, preventing water accumulation that could affect film quality and subsequent operations.
