Description

Technical Field

[0001] The utility model relates to the field of plastic film processing equipment, in particular to a plastic film surface embossing device. Background Art

[0002] Plastic film embossing refers to a processing method that forms textures, patterns or designs on the surface of plastic film. By mechanically pressing or hot pressing the plastic film, uneven patterns can be produced on the surface of the film, thereby achieving a decorative effect or increasing the surface friction of the material. The general plastic film surface embossing device is mainly composed of a rubber cylinder, an embossing roller and a structure that assists the film transmission. The film passes through the rubber cylinder and is then clamped between the embossing roller and the rubber cylinder. By controlling the pressure, it contacts the film and applies sufficient hot pressure to cooperate with the rubber cylinder to emboss the pattern on the film surface. The heating can soften the plastic film and increase its flexibility, making it easier to perform the embossing operation.

[0003] After embossing, the surface needs to be cooled to prevent the embossed pattern from being flattened again when the film is rolled up, making the pattern unclear. Existing techniques generally use natural cooling and assisted cooling to cool the film, but these methods often result in long cooling times or incomplete cooling. Utility Model Content

[0004] In order to solve the above-mentioned problems in the prior art, the utility model provides a device for embossing the surface of a plastic film, which can help improve the cooling efficiency of the plastic film.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a plastic film surface embossing device, comprising a chassis, a feed port and a discharge port; the top and bottom of the chassis are respectively provided with a feed port and a discharge port; the interior of the chassis is provided with a heating zone, an embossing zone and a cooling zone which are connected in sequence from top to bottom, and the heating zone, the embossing zone and the cooling zone are separated by partitions; a heating mechanism is provided in the heating zone, a embossing mechanism is provided in the embossing zone, and a cooling mechanism is provided in the cooling zone.

[0006] The heating mechanism consists of two sets of connecting rods, heating plates, and heating wires. The two connecting rods are arranged horizontally, with opposite ends connected to a heating plate. Heating wires are located on opposite sides of the two heating plates, and the other ends of the connecting rods are connected to the inner wall of the chassis. The heating wires are electrically connected to a temperature controller located on the outer wall of the chassis. After the film enters the heating zone through the feed port at the top of the chassis and passes between the two heating plates, the film is heated and softened on both sides, facilitating subsequent embossing.

[0007] The embossing mechanism is composed of two embossing rollers connected to the inner wall of the chassis. The heated film passes between the two embossing rollers and is squeezed and embossed.

[0008] The cooling mechanism is composed of two cooling air blowers, the air outlets of the two cooling air blowers are oriented toward the center of the cooling zone; the embossed film passes between the two cooling air blowers, is cooled and solidified, and is then discharged from the discharge port for storage.

[0009] The connecting rod is an electric telescopic rod, and the controller of the electric telescopic rod is installed on the outer wall of the chassis; the controller can remotely control the telescopic length of the two connecting rods, thereby controlling the distance between the heating plate and the film, that is, the distance between the two heating plates can be adjusted according to the heat resistance of the film.

[0010] The top and bottom of the chassis are respectively provided with receiving rollers. The receiving roller on the top of the chassis is used for winding and receiving the film to be embossed, and the receiving roller on the bottom of the chassis is used for winding and receiving the film after embossing.

[0011] The bottom end of the chassis is provided with supporting legs, which can raise the chassis so that there is a certain space below the storage roller and the discharge port, which is convenient for storage operation.

[0012] The outer wall of the chassis is provided with a transparent observation window, which is convenient for staff to observe the working status of each internal area from the outside. After opening the transparent observation window, internal components can also be installed and replaced.

[0013] The beneficial effects of the utility model are:

[0014] The plastic film surface embossing device can realize the entire process of feeding, heating, embossing, cooling, discharging and storing the plastic film, with high working efficiency;

[0015] The distance between the two heating plates in the heating mechanism and the temperature of the heating wire are adjustable, so that the distance between the heating plates and the film and the heating temperature of the heating wire can be adjusted according to the properties of different plastic films, so as to heat and soften the film more accurately;

[0016] The layout of the heating zone, ginning zone and cooling zone is reasonable. The ginning zone is between the heating zone and the cooling zone, which lengthens the distance between the heating zone and the cooling zone and reduces the impact of air mixing in the two zones on their respective heating and cooling. In addition, the three zones are distributed vertically. The hot air in the upper heating zone mainly flows upward, and the cold air in the lower cooling zone mainly flows downward, further reducing the impact of regional temperature.
