Description

Technical Field

[0001] The invention relates to the technical field of plastic film processing, and in particular to an extrusion shaping device for a textured TPU film and a use method thereof. Background Art

[0002] Double-glazing, also known as insulating glass, is composed of two layers of flat glass. Most system doors and windows will have inert gas filled in the middle of the double-glazing. Because of this structure, double-glazing has good heat insulation, sound insulation and thermal insulation. Some insulating glass will fill the gap with some high-density glue and then stick it with a sealing strip. Some insulating glass will use a plastic film with a certain elasticity in the middle to buffer the rigid contact between the two layers of glass. At the same time, different patterns can be formed on the surface of the plastic film and the refraction effect of the insulating glass can be changed, so that light passes through the insulating glass to form a scattering effect to prevent peeping.

[0003] When processing the plastic film, in order to form different patterns on the plastic film, different shapes are generally applied to the opening of the extruded plastic film to directly form corresponding patterns on the plastic film, or a cooling roller with a pattern on the surface is used to extrude the plastic surface that has not been completely cooled and solidified by one or two cooling rollers to form patterns. However, multiple embossings are required to form complex patterns with high precision, and after multiple embossings, the pattern on the plastic film cannot accurately correspond to the patterns on different shaping rollers (cooling rollers) in the horizontal direction and in its moving direction, which can easily cause the pattern on the next shaping roller to deviate from the pattern on the plastic film and affect the pattern effect.

At the same time, the upper and lower texture strips can also be aligned, further increasing the position accuracy of the texture on both sides of the plastic film. The texture strip is detachably connected to the upper mold and the lower mold, and thus when processing different plastic film textures, the production of different products can be completed by replacing the texture strips.

[0023] By adopting the above technical scheme, according to the different specifications of the texture strips and texture sleeves, the calibration strips with different texture structures are slid into the connecting slot, and then the block is inserted into the opening of the connecting slot, and the block is squeezed into the calibration strip in the connecting slot by using a screw. At the same time, there is a threaded column on the other side that abuts against the surface of the calibration strip. The position of the calibration strip in the connecting slot is controlled by rotating the screw and the threaded column, and then the relative position of the two calibration strips is controlled. Then, the structure of the rotating protrusion in the through groove and rotatably connected to the rotating shaft is used to enable the two calibration strips to rotate. Then, the calibration strip is inserted into the texture on the surface of the texture strip and the texture sleeve by using the texture of the calibration strip that is embedded with the texture of the texture strip and the texture sleeve, so as to complete the position control of the extrusion die and the shaping component at a relatively long distance, thereby improving product quality.

[0024] In summary, the present invention has the following beneficial effects: First, a pattern strip is used to form a positioning pattern on the surface of the plastic film, and the pattern sleeve is then aligned with the pattern to complete the positioning, and the pattern sleeve is then used to press out the remaining patterns on the plastic film, thereby forming complex patterns on the plastic film, thereby preventing quality problems from occurring when complex patterns with large depths of concave and convex are formed at one time, and also increasing the quality of the patterns on the plastic film.

[0025] Secondly, the upper and lower texture strips and the texture on the texture sleeve are aligned when calibrating the assembly to further increase the positional accuracy and quality of the texture on the plastic film.

[0026] Third, by utilizing the calibration components and the detachable connection between the texture strips, calibration strips, and texture sleeves, different texture strips and texture sleeves can be replaced to extrude and shape both sides of the plastic when producing different types of plastic films. At the same time, the position of the texture strip can be adjusted by adjusting the components and aligned with the texture on the texture sleeve to increase product quality.

[0035] First, according to the product type, the texture strips 12 with different textures are installed on the upper mold 11 and the lower mold 27, the texture sleeves 30 with different textures are installed on the sealing sleeve 31, and the calibration strips 41 with different textures are installed on the extension plate 39 and the rotating block 42, wherein the calibration strip 41 on the rotating block 42 corresponds to the texture of the two texture strips 12, and the calibration strip 41 on the extension plate 39 corresponds to the texture on the texture sleeve 30. If it is necessary to shape the plastic film on one side, the upper texture strip 12 and the upper texture sleeve 30 are uneven textures, and the texture strip 12 at the lower position and the texture sleeve 30 at the lower position are flat structures, and then the corresponding texture is processed on one side of the plastic film, and then the cooling water is introduced into the connecting cavity 33 through the connecting pipe 47 by using the external water supply system, and the cooling water then passes through the cooling groove 32 and enters the other side. The cooling water flows into the connecting cavity 33 at one end and flows out to the return water port of the external water supply system through the connecting pipe 47 at the other end, thereby completing the circulation of the cooling water. The textured sleeve 30 made of copper material is used to increase the heat exchange between the cooling water and the plastic film. At the same time, the sealing sleeve 31 made of polyurethane foam material is used to reduce the heat exchange between the cooling water and the intermediate shaft 29, so that the cooling water only absorbs the heat from the textured sleeve 30 and the plastic film, and the energy loss can be further reduced when the plastic film is cooled and formed. At the same time, the sealing sleeve 31 made of polyurethane foam material also has a certain toughness, so that when the textured sleeve 30 is put on the outer periphery of the sealing sleeve 31, the concave on the outer periphery of the sealing sleeve 31 and the concave on the inner wall of the textured sleeve 30 are used to form the cooling groove 32. The toughness and softness of the textured sleeve 30 and the sealing sleeve 31 are used to increase the sealing of the cooling groove 32, thereby increasing the use effect. The calibration strip 41 on the rotating block 42 corresponds to the texture on the texture strip 12, and the texture of the calibration strip 41 on the extension plate 39 corresponds to the surface texture of the texture sleeve 30.

When the texture strip 12 is installed in the receiving groove 14 on the upper mold 11 and the lower mold 27, the end of the connecting rod 16 away from the lifting thread 19 is first pulled out of the receiving groove 14, and the rotating shaft is inserted into the end of the connecting rod 16 and rotatably connected to one end of the texture strip 12, and then the texture strip 12 is inserted inward from the opening position of the receiving groove 14, and the positions of the two ends of the texture strip 12 are located outside the projection of the extrusion channel 13 on the horizontal plane, and then the pressing plate 23 is inserted into it from the opening of the receiving groove 26, and the pressing plate 23 is inserted into it. The pressing block 24 on the pressing plate 23 is in contact with the surface of the grain strip 12, and then the locking stud 25 is threadedly connected to the bottom wall of the receiving groove 26, and the locking stud 25 is rotated to drive the pressing plate 23 to move downward, and the pressing plate 23 drives the pressing block 24 to press the surface of the grain strip 12 and connect the grain strip 12 with the upper mold 11 or the lower mold 27 as a whole, wherein the grain on the grain strip 12 coincides with the extrusion channel 13 on the horizontal plane, and the grain on it extends upward into the extrusion channel 13, and then the grain of the calibration strip 41 on the extension plate 39 is inserted into the grain sleeve 30. The texture of the calibration strip 41 on the rotating block 42 is inserted into the texture strip 12 below, and the textures on the two are embedded, and then the locking studs 25 at the upper and lower positions are appropriately loosened to reduce the pressure of the clamping block 24 on the texture strip 12, and then the lifting thread 19 is rotated, and the lifting thread 19 drives the threaded slider 18 to move up and down. The threaded slider 18 drives one end of the connecting rod 16 to move up and down through the connecting block 17, and then drives the height difference of one end of the connecting rod 16 relative to the texture strip 12. When the connecting rod 16 on one side is in a horizontal state, the connecting rod 16 pushes the texture strip 12.
