[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown in the figure, a color printing device for producing plastic packaging films includes: a base 3, on the upper end surface of the base 3, a housing 11 is fixedly arranged, and universal wheels 4 are symmetrically installed at the bottom end of the base 3, facilitating the movement of the entire device.

[0025] On the upper end surface of the base 3 and at a position outside the housing 11, two fixed plates 7 are fixedly connected. On one side of the two fixed plates 7 close to each other, the same material feeding roller 8 is rotatably connected, and a plastic packaging film is wound around the material feeding roller 8.

[0026] On the lower inner wall of the housing 11, a pigment box 2 is fixedly arranged. The pigment box 2 is in a "U" shape, and pigments are arranged inside the pigment box 2. Between the front inner wall and the rear inner wall of the pigment box 2, a color printing roller 9 is rotatably connected. Between the front inner wall and the rear inner wall of the housing 11, an imprinting roller 10 is rotatably connected. The imprinting roller 10 is located directly above the color printing roller 9. Both the color printing roller 9 and the imprinting roller 10 are driven to rotate by motors.

[0027] An exhaust pipe 12 is fixedly inserted into the upper end of the housing 11. The function of the exhaust pipe 12 is to discharge the gas or steam inside the housing 11. In the color printing device, when the device operates for a long time, gas or steam may be generated inside. If it is not discharged in time, it may cause the internal pressure of the device to be too high or the temperature to be overheated.

[0028] On one side of the housing 11, a feed inlet is provided, and on the other side of the housing 11, a discharge outlet is provided. Between the front inner wall and the rear inner wall of the discharge outlet, two limiting rollers 14 are rotatably connected. One of the limiting rollers 14 is located directly above the other limiting roller 14. The plastic packaging film on the material feeding roller 8 passes through the feed inlet, the gap between the imprinting roller 10 and the color printing roller 9, and the gap between the two limiting rollers 14 in sequence, and finally leads to the outside.

[0029] During the color printing process, the limiting rollers 14 help control the position and movement direction of the plastic packaging film, ensure the correct position of the plastic packaging film between the color printing roller 9 and the imprinting roller 10, so as to achieve an accurate color printing effect. The limiting rollers 14 can play a role in positioning and guiding.

[0030] On the lower inner wall of the housing 11, a hair dryer 16 is fixedly arranged. The upper end of the hair dryer 16 is open. Air inlets 5 are provided on both sides of the hair dryer 16 and close to the bottom end. A hair dryer 6 is arranged inside the hair dryer 16, and a heating wire 13 is fixedly arranged inside the hair dryer 16 and above the hair dryer 6.

[0031] When in use, the external device pulls the plastic packaging film to the right, so that the discharge roller 8 rotates to discharge the material, and the color printing roller 9 and the impression roller 10 are controlled to rotate. The color printing roller 9 rotates to pick up the pigment from the pigment frame 2. Under the joint action of the color printing roller 9 and the impression roller 10, the ink attached to the surface of the color printing roller 9 can be printed on the plastic packaging film. The hair dryer 6 is started to work, and the heating wire 13 can emit heat. The hair dryer 6 blows the heat to the lower surface of the plastic packaging film to achieve rapid drying of the ink, thereby preventing the ink from drying and affecting the next step of production.

[0032] When the color printing roller 9 transfers the pigment to the plastic packaging film, not all parts of the lower surface of the plastic packaging film are stained with pigment, and some parts of the lower surface of the plastic packaging film are not stained with pigment. If the hair dryer 6 is fixedly arranged, the hair dryer 6 needs to blow air to the entire lower surface of the plastic packaging film, and it is necessary to ensure that the wind can cover the entire lower surface of the plastic packaging film. When the hair dryer 6 blows air to the entire lower surface of the plastic packaging film, it will also blow air to the parts that are not stained with pigment, resulting in a waste of wind power.

[0033] A camera 1 is fixedly arranged on the side of the paint frame 2, and a controller is arranged on the outer side of the shell 11. The camera 1 is electrically connected to the controller. The camera 1 can monitor in real time the situation of the color printing roller 9 transferring the paint to the plastic packaging film. The camera 1 transmits the image data to the controller. The image transmitted by the camera 1 can be seen through the video monitoring software pre-installed in the controller. The staff can clearly see the contamination of the paint on the lower surface of the plastic packaging film based on the image.

[0034] The hair dryer 6 is rotatably arranged inside the hair dryer tube 16, and the hair dryer 6 includes a protective shell 61, a dust cover 62, a fixed shaft 63, and fan blades 64. A rotating motor is fixedly arranged inside the protective shell 61, and the output shaft of the rotating motor is fixedly connected to the fixed shaft 63. The circumferential rotation of the fixed shaft 63 is connected to multiple fan blades 64. A dust cover 62 is fixedly arranged outside the fan blades 64, and the bottom end of the dust cover 62 is connected to the protective shell 61. The dust cover 62 is used to protect the fan blades 64 and the fixed shaft 63.

[0035] A rotating shaft 15 is rotatably connected between the two inner walls of the hair dryer 16, and a protective shell 61 is fixedly sleeved on the outer side of the rotating shaft 15. The rotating shaft 15 can drive the protective shell 61 to rotate together. A driving motor 19 is fixedly provided on the inner wall of the lower end of the hair dryer 16. A worm 18 is fixedly connected to the output shaft of the driving motor 19. The worm 18 is vertically provided. A turbine 17 is fixedly sleeved on the outer side of the rotating shaft 15. The turbine 17 is meshed with the worm 18. When the driving motor 19 is started, the output shaft of the driving motor 19 drives the worm 18 to rotate. The worm 18 drives the rotating shaft 15 to rotate by meshing with the turbine 17. Since the protective shell 61 is fixedly sleeved on the rotating shaft 15, the rotating shaft 15 drives the protective shell 61 to rotate.

[0036] Each fan blade 64 can rotate: a plurality of power motors 65 are fixedly arranged inside the fixed shaft 63, the number of the power motors 65 is the same as the number of the fan blades 64, and the power motors 65 are arranged corresponding to the fan blades 64, and the output shaft of the power motor 65 passes through the side wall of the fixed shaft 63 and is fixedly connected to the corresponding fan blade 64.

[0037] Working principle:

[0038] When in use, the camera 1 monitors the color printing roller 9 transmitting the pigment to the plastic packaging film in real time, and the camera 1 transmits the image data to the controller. The image transmitted by the camera 1 can be seen through the video monitoring software pre-installed in the controller. The staff can clearly see the contamination of the pigment on the lower surface of the plastic packaging film according to the image. The controller calculates the time when the pigment part on the plastic packaging film reaches the top of the hair dryer 6. The staff starts the driving motor 19 and rotates the motor according to the arrival time, so that the position of the hair dryer 6 is deflected and the hair dryer 6 is blown. The hair dryer 6 is rotated to the position aligned with the pigment part, and the multiple fan blades 64 are rotated to blow the pigment part, and the part without the pigment will not be blown, saving electricity.

[0039] At the same time, the power motor 65 can also be started, and the output shaft of the power motor 65 drives the corresponding fan blades 64 to rotate. Changing the angle of the fan blades 64 can adjust the wind direction of the hair dryer 6. Adjusting the angle of the fan blades 64 to a suitable position can allow air to flow in a specific direction, ensuring that the wind blows toward the paint area.

[0040] It should be noted that: this solution is only applicable when the pigment on the lower surface of the plastic packaging film is regular. The pigment is either near the front end, near the rear end, or in the middle. The pigment cannot be evenly distributed on the lower surface of the plastic packaging film in a scattered manner.

[0041] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
