Embodiment Construction
[0023] The following is further described in detail through specific implementation methods:
[0024] The reference signs in the drawings of the description include: material box 1, screw feed pipe 2, extrusion die 3, cooling box 4, pipeline 5, extrusion mechanism 6, guide roller 7, receiving roller 8, third motor 9 , the first support frame 10, the cross bar 11, the switch 12, the second support frame 13, the casing 14, the gear 15, the rack 16, the plate 17, the second discharge roller 18, the first discharge roller 19.
[0025] Such as figure 1 The production device of the shown IPE blown film includes an extruding mechanism, a cooling mechanism, an extruding mechanism 6 and a winding mechanism connected in sequence. The extrusion mechanism includes a material box 1 connected in sequence, a screw feed pipe 2 and an extrusion die 3. The temperature of the extrusion die 3 is controlled between 160-190°C, but the temperature can be adjusted according to the actual situation. ...

The invention belongs to the field of film processing, and particularly relates to a production device for an IPE blow molding film. The production device comprises an extruding mechanism, a cooling mechanism, a squeezing mechanism and a winding mechanism which are sequentially arranged; and the squeezing mechanism comprises a box body, two wedge surfaces are arranged in the box body by taking thehorizontal center line of the box body as the symmetric line, the two wedge surfaces jointly form a herringbone channel, plates sliding in the inclination direction of the wedge surfaces are slidablyconnected to the two wedge surfaces separately, and the plates are both connected with a power unit. In order to solve the problems that in the prior art, the herringbone plate angle adjusting process is very complicated, and film bubbles generate folds due to the fact that the adjusting angle and amplitude of the two plates of the herringbone plate are not prone to keeping consistent, the production device with the structure achieves the effect that the tightening angles of the plates are consistent through the fixed angles of the two sides of the herringbone channel.
Description
technical field [0001] The invention belongs to the field of film processing, and in particular relates to a production device for IPE blown film. Background technique [0002] A film is a thin, flexible, transparent sheet made of plastic, adhesive, rubber, or other material. Now it has been widely used in packaging, agriculture, industry and many other fields. Film can be divided into polyethylene film, polypropylene film, polyvinyl chloride film and polyester film according to different raw materials, and can be divided into blown film, cast film and calendered film according to different molding methods. Most of the existing blown film production processes include: feeding, melting and plasticizing, extruding film tubes, inflation, cooling and setting, clamping, traction and coiling, and other processes. Each process is important to the quality of the final film. Impact. [0003] The current production process generally uses a herringbone plate to flatten the bubble of...
