Description

Technical Field

[0001] The invention relates to the technical field of plastic packaging film forming, in particular to a plastic packaging film forming device. Background Art

[0002] Plastic film is a plastic product made of a uniform mixture of polymer synthetic materials and other auxiliary materials in a certain proportion. It has a specific thickness (usually between 0.01 and 0.25 mm), width and length, and a flat, smooth and soft surface.

[0003] Plastic film has the following characteristics: Material and thickness: Made of a variety of polymer materials, such as polyethylene, polypropylene, polyvinyl chloride, etc., with a wide range of thicknesses, suitable for different needs, Appearance and touch: The surface is flat, smooth and soft, and some products may be transparent or translucent, Physical properties: Good flexibility, wear resistance, corrosion resistance, and some products also have waterproof, moisture-proof, antibacterial and other functions;

When the threaded transport plate rotates, the raw material in the left connecting seat is transported to the right connecting seat.

[0021] S3: The raw material falls into the feed pipe from the right connecting seat, and then enters the extrusion chamber. After the raw material in the feed pipe is finished entering, the control console controls the first solenoid valve to close and the electric heating tube to start. The electric heating tube increases the temperature inside the extrusion chamber to melt the raw material in the extrusion chamber, controls the second solenoid valve on the extrusion head to open, and the second electric hydraulic rod drives the extrusion plate to move, extruding the melted raw material in the extrusion chamber, so that the melted raw material is discharged from the extrusion head, which can control the amount of the melted raw material extruded, which is helpful to control the thickness of the film;

[0024] (1) The present invention adjusts the feeding speed of the raw materials through the rotation amplitude of the electric regulating valve, thereby avoiding blockage caused by too fast feeding speed or production interruption caused by too slow feeding speed. The rotation speed of the servo motor output shaft is controlled to adjust the feeding speed of the raw materials, which helps to produce a film with uniform thickness and stable performance, thereby achieving the effect of controlling the feeding speed of the raw materials.

[0025] (2) The present invention drives the H-shaped movable plate to move by the first electric hydraulic rod. When the H-shaped movable plate moves, the horizontal height of the movable seat changes, thereby changing the height of the lower end of the connecting rod. When the connecting rod moves, the closing of the front and rear sealing frames is controlled, which facilitates the cleaning of the sealing frames and the raw materials in the connecting seat, avoids the accumulation of raw materials in the sealing frames and the connecting seat, and achieves the effect of quickly cleaning the inner wall of the sealing frame and the connecting seat.

[0026] (3) The present invention increases the temperature inside the extrusion bin through the electric heating tube, so that the raw materials in the extrusion bin melt. The second electric hydraulic rod drives the extrusion plate to move, and extrude the melted raw materials in the extrusion bin, so that the melted raw materials are discharged from the extrusion head. The amount of the melted raw materials extruded can be controlled, thereby achieving the effect of controlling the thickness of the film production.

[0027] (4) The present invention drives the T-shaped positioning frame and the driving rod to move horizontally through the adjusting rod. When the driving rod moves, it drives the partition to move synchronously, thereby adjusting the spraying area at the lower end of the extrusion head, and then controlling the width of the film after production. It can be adjusted according to production needs to achieve the effect of controlling the production width of the film. BRIEF DESCRIPTION OF THE DRAWINGS

10. A plastic packaging film forming process, characterized in that: The following steps are involved: S1: Pour the raw materials from the feed hopper (41) into the connecting pipe (42), and the control console (3) controls the electric regulating valve (46) to rotate, and adjusts the feeding speed of the raw materials according to the rotation amplitude of the electric regulating valve (46) to avoid blockage caused by too fast feeding speed or production interruption caused by too slow feeding speed; S2: The raw material falls from the connecting tube (42) into the left connecting seat (43), and the servo motor starts to work, driving the rotating rod (412) to rotate, and the rotating rod (412) drives the threaded transport plate (413) to rotate. When the threaded transport plate (413) rotates, the raw material in the left connecting seat (43) is transported to the right connecting seat (43). By controlling the rotation speed of the servo motor output shaft, the feeding speed of the raw material can be adjusted, which helps to produce a film with uniform thickness and stable performance; S3: The raw material falls from the right connecting seat (43) into the feed pipe (52) and then into the extrusion chamber (51). After the raw material in the feed pipe (52) has finished entering, the control console (3) controls the first electromagnetic valve (53) to close and the electric heating tube (510) to start. The electric heating tube (510) increases the internal temperature of the extrusion chamber (51) to melt the raw material in the extrusion chamber (51). The second electromagnetic valve on the extrusion head (511) is controlled to open, and the second electric hydraulic rod (55) drives the extrusion plate (56) to move, extruding the melted raw material in the extrusion chamber (51) so that the melted raw material is discharged from the extrusion head (511). The amount of the melted raw material extruded can be controlled, which helps to control the thickness of the film. S4: The electric slide rail (513) drives the sliding seat (515) to move, the sliding seat (515) drives the extrusion chamber (51) and the extrusion head (511) to move synchronously, the output cylinder (66) drives the T-shaped moving frame (65) to move, the T-shaped moving frame (65) drives the adjusting rod (67) to move, the adjusting rod (67) drives the T-shaped positioning frame (68) and the driving rod (69) to move horizontally, and when the driving rod (69) moves, it drives the partition (63) to move synchronously, thereby adjusting the spraying area at the lower end of the extrusion head (511), thereby controlling the width of the film after production, and can be adjusted according to production needs.
