Description

TECHNICAL FIELD

[0001] The utility model relates to heating film printing processing equipment technical field, especially a kind of printing device for heating film. BACKGROUND

[0002] Heating film is a kind of translucent polyester film that can generate heat after being electrified, which is made of special conductive ink and metal current-carrying strip by processing and hot pressing between insulating polyester film. When working, heating film is used as a heating body to send heat into space in the form of radiation, so that the human body and objects can obtain warmth, and its comprehensive effect is better than that of traditional convection heating method.

[0003] At present, heating film usually needs to print marks or patterns on the surface before leaving the factory, so as to be distinguished and sold. The existing factory often uses pad printing machine to print patterns on heating film, and its principle is to etch patterns on printing flat plate, then coat ink on etching plate, and finally transfer ink to heating film by silicone head. However, since heating film is generally long, and the printing processing table space of pad printing machine is small, workers usually need to manually press heating film on printing processing table during printing process, so as to ensure that silicone head can transfer ink to the specified position of heating film. In addition, UV ink is often used for printing patterns on heating film, and UV ink needs to be cured by ultraviolet irradiation immediately after printing. Therefore, workers need to manually transfer heating film into and out of ultraviolet lamp box after printing each heating film, which leads to high intensity and low efficiency of heating film printing work.

The rotating plate one is located diagonally above the rotating plate two, and when the rotating plate one and the rotating plate two are closest to each other on their respective sides away from their rotation centers, the rotating plate one and the rotating plate two are flush with each other. A baffle two is fixedly installed on one side of the rotating plate two, and the baffle two and the rotating shaft two are perpendicular to each other, with the rotating shaft two fixedly passing through the baffle two.

[0006] A further feature of this invention is that a pair of horizontal guide rods are fixedly installed inside the box, and the two guide rods move through the sliding table.

[0007] A further feature of this invention is as follows: a U-shaped frame is fixed to one side of the box body with screws; a rotating shaft is located in the middle of the U-shaped frame, and both ends rotate through the two side plates of the U-shaped frame; a worm gear reducer motor is fixed to the outer wall of one side plate of the U-shaped frame, and its output end is fixedly connected to one end of the rotating shaft that extends out of the side plate of the U-shaped frame; a worm gear reducer motor is fixed to the outer wall of the side plate of the ultraviolet irradiation cabinet, and one end of the rotating shaft rotates through the side plate and is fixedly connected to the output end of the worm gear reducer motor.

[0008] A further feature of this invention is that: the two side panels of the ultraviolet irradiation cabinet are respectively fixedly provided with diagonal braces supporting the bottom of the two side panels of the U-shaped frame; a pair of support plates are fixedly provided on the outer wall of the back panel of the ultraviolet irradiation cabinet, and one side of the two support plates is flush with the outer wall of the two side panels of the ultraviolet irradiation cabinet; the upper and lower ends of the support plates are respectively fixedly connected to the box body and the base.

[0009] A further feature of this invention is that a stop bar is fixedly connected to one side of the flip plate, the stop bar and the flip plate are perpendicular to each other, and the rotation shaft passes through the stop bar.

[0010] A further feature of this invention is that a U-shaped guardrail made of transparent material is fixedly installed on the second baffle, and the two sides of the U-shaped guardrail are flush with the two sides of the second flip plate.

[0011] A further feature of this invention is that a square receiving groove is provided on the base, the square receiving groove is located below the first flip plate and on one side of the second flip plate, and a right-angled trapezoidal slope is fixedly provided on the side of the square receiving groove near the second flip plate.

[0012] A further feature of this invention is that a rectangular groove is provided on the inner wall of the back panel of the ultraviolet irradiation cabinet, and the ultraviolet lamp is vertically fixed in the rectangular groove.

[0013] A further feature of this invention is that a baffle is fixedly provided at the bottom of the U-shaped frame. When the first flip plate and the second flip plate are flush with each other, the baffle is perpendicular to the first flip plate or the second flip plate, and the lower end of the baffle is located above the gap between the first flip plate and the second flip plate.

[0014] A further feature of this invention is that the sliding assembly includes a lead screw that is horizontally rotatably disposed inside the box and moves through the sliding table, a nut fixed on the sliding table and threadedly connected to the lead screw, and a servo motor that drives the lead screw to rotate.

Figure 1 and attached Figure 2 After the heating film printing is completed, the worm gear reducer motor one drives the rotating shaft one to rotate, causing the flip plate one connected to the rotating shaft one to flip downwards. Once the flip plate one is flush with the flip plate two, the heating film on the flip plate one will slide down onto the flip plate two under gravity and be inserted obliquely into the slot formed by the U-shaped guardrail and the baffle two. Then, the worm gear reducer motor two drives the rotating shaft two to rotate, causing the flip plate two connected to the rotating shaft two to flip inwards into the UV irradiation cabinet. Once the flip plate two is vertical and the UV irradiation cabinet is closed... After the heating film is placed inside the UV irradiation cabinet, the UV lamp inside the cabinet is turned on to cure the UV ink printed on the heating film. After the curing process is completed, the UV lamp is turned off, and the worm gear reducer motor drives the rotating shaft in the opposite direction, causing the flip plate to flip in the opposite direction until one end of the flip plate extends into the square receiving groove of the base. At this point, the heating film, which has finished curing, slides down the flip plate again and into the square receiving groove, thus achieving the automatic feeding effect of the heating film.

[0016] The above-mentioned heating film printing and curing process is fully automated except for material feeding. This not only greatly reduces the labor intensity of manual labor, but also ensures a fast and smooth transition between the two processes of preliminary printing and curing. Furthermore, it can automatically unload the material after completion. Therefore, it is more efficient than traditional pad printing machines and UV light boxes that process heating films separately. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: A printing apparatus for heating films, such as Figures 1-4As shown, the device includes a base 1, a UV irradiation cabinet 2 fixed to the base 1, multiple vertically arranged UV lamps 3 fixed inside the UV irradiation cabinet 2, a box 4 fixed to the top of the UV irradiation cabinet 2, a sliding table 5 sliding inside the box 4, a sliding assembly 6 driving the sliding table 5 to slide relative to the inside of the box 4, a pad printing machine 7 mounted on the sliding table 5, a rotating shaft 8 horizontally rotatably mounted on one side of the box 4, a worm gear reducer motor 9 driving the rotating shaft 8, a flip plate 10 fixedly connected to the rotating shaft 8 on one side, a rotating shaft 1a rotatably mounted inside the UV irradiation cabinet 2, a worm gear reducer motor 1b driving the rotating shaft 1a, and a worm gear reducer motor 1b fixedly connected to the rotating shaft 1a on one side. The second flip plate 1c is located on one side of the rotating shaft 8, with the opening of the UV irradiation cabinet 2 facing the box body 4. The irradiation direction of the UV lamp 3 is directly facing the opening of the UV irradiation cabinet 2. The rotating shaft 1a and the second flip plate 1c are close to the opening of the UV irradiation cabinet 2. When the second flip plate 1c is vertical, it can close the opening of the UV irradiation cabinet 2. The first flip plate 10 is located diagonally above the second flip plate 1c. When the first flip plate 10 and the second flip plate 1c are closest to each other on the side away from their respective rotation centers, the first flip plate 10 and the second flip plate 1c are flush with each other. A second baffle 1c1 is fixedly installed on one side of the second flip plate 1c. The second baffle 1c1 and the second flip plate 1c are perpendicular to each other, and the rotating shaft 1a is fixedly passed through the second baffle 1c1.

[0025] By using the above-mentioned pad printing device, not only can the automatic printing and automatic curing of the heating film be achieved, but also the sliding table 5 can be controlled by the sliding component 6 to adjust the printing position of the pad printing machine 7 to a certain extent, thereby adapting to heating films of different lengths and meeting the needs of different printing positions. By using the above-mentioned baffle 1c1, not only can the heating film be prevented from sliding off the flip plate 1c before curing preparation, but it can also support and position the heating film, ensuring that the printing side of the heating film is fully irradiated by the ultraviolet lamp 3.

[0026] Furthermore, a pair of horizontal guide rods 41 are fixedly installed inside the box body 4, and the two guide rods 41 move through the sliding table 5 to ensure the sliding stability of the sliding table 5.

[0027] Furthermore, a U-shaped frame 1d is fixed to one side of the housing 4 with screws. A rotating shaft 8 is located in the middle of the U-shaped frame 1d, with both ends rotating through the side plates of the U-shaped frame 1d. A worm gear reducer motor 9 is fixed to the outer wall of one side plate of the U-shaped frame, and its output end is fixedly connected to one end of the rotating shaft 8 that extends out of the side plate of the U-shaped frame 1d. A second worm gear reducer motor 1b is fixed to the outer wall of the side plate of the ultraviolet irradiation cabinet 2. One end of a rotating shaft 1a rotates through the side plate and is fixedly connected to the output end of the second worm gear reducer motor 1b. By adopting the above-mentioned installation method of the U-shaped frame 1d, the worm gear reducer motor 9, and the worm gear reducer motor 1b, the rotational stability of the rotating shaft 8 and the operational stability of the worm gear reducer motors 9 and 1b can be effectively ensured.

[0028] Furthermore, each of the two side panels of the ultraviolet irradiation cabinet 2 is fixedly equipped with diagonal braces 21 supporting the bottom of the U-shaped frame 1d. A pair of support plates 22 are fixedly installed on the outer wall of the back panel of the ultraviolet irradiation cabinet 2, with one side of the two support plates 22 flush with the outer wall of the two side panels of the ultraviolet irradiation cabinet 2. The upper and lower ends of the support plates 22 are fixedly connected to the box body 4 and the base 1, respectively. By adopting the above-mentioned diagonal braces 21 and support plates 22, the structural strength of this device can be improved to ensure the stable operation of each component of this device.

[0029] Furthermore, a baffle strip 101 is fixedly connected to one side of the flip plate 10. The baffle strip 101 and the flip plate 10 are perpendicular to each other, and the rotating shaft 8 is fixedly passed through the baffle strip 101. By using the baffle strip 101, the position of the heating film can be easily positioned on the flip plate 10 to ensure the printing quality of the heating film.

[0030] Furthermore, a transparent U-shaped guardrail 1c2 is fixedly installed on the second baffle 1c1, with both sides of the U-shaped guardrail 1c2 flush with both sides of the second flip plate 1c. By using the above-mentioned U-shaped guardrail 1c2, the heating film can be prevented from tipping over and falling into the ultraviolet irradiation cabinet 2 when the second flip plate 1c is in a vertical position.

[0031] Furthermore, a square receiving groove 11 is provided on the base 1, which is located below the first flip plate 10 and on one side of the second flip plate 1c; a right-angled trapezoidal ramp 12 is fixedly provided on the side of the square receiving groove 11 near the second flip plate 1c. By using the above-mentioned square receiving groove 11 and ramp 12, it can cooperate with the second flip plate 1c to flip, effectively realizing the automatic feeding effect of the heating film.

[0032] Furthermore, a rectangular groove 23 is provided on the inner wall of the back panel of the ultraviolet irradiation cabinet 2, and the ultraviolet lamp 3 is vertically fixed in the rectangular groove 23. The rectangular groove 23 mentioned above can not only effectively protect the ultraviolet lamp 3, but also better concentrate the ultraviolet light, making the ultraviolet light more concentrated.

[0033] Furthermore, a baffle 1f is fixedly installed at the bottom of the U-shaped frame 1d. When the first flip plate 10 and the second flip plate 1c are aligned with each other, the baffle 1f is perpendicular to either the first flip plate 10 or the second flip plate 1c, and the lower end of the baffle 1f is located above the gap between the first flip plate 10 and the second flip plate 1c. By using the baffle 1f, the downward movement of the heating film can be hindered before the first flip plate 10 is aligned with the second flip plate 1c, so as to prevent the heating film from falling too fast during this stage and thus falling onto the second flip plate 1c or flying into the ultraviolet irradiation cabinet 2 prematurely.

[0034] Furthermore, the sliding assembly 6 includes a lead screw 61 horizontally rotatably disposed inside the housing 4 and moving through the sliding platform 5, a nut 62 fixed to the sliding platform 5 and threadedly connected to the lead screw 61, and a servo motor 63 driving the lead screw 61 to rotate. The servo motor 63 is fixed to the outer wall of the side plate of the housing 4, and one end of the lead screw 61 rotates out of the side plate of the housing 4 and is fixedly connected to the output end of the servo motor 63. By using the above-mentioned sliding assembly 6, when the sliding platform 5 needs to slide, the servo motor 63 is started to drive the lead screw 61 to rotate. Then, the nut 62 threadedly connected to the lead screw 61 will move forward or backward along the axis of the lead screw 61 under the rotation of the lead screw 61. Finally, the sliding platform 5 will slide relative to the housing 4 under the drive of the nut 62.

[0035] The working principle of this embodiment:

[0036] When printing heating film, first place the heating film on the horizontal flip plate 10, then turn on the pad printing machine 7 on the sliding table 5 to initially print the heating film. After the heating film printing is completed, the worm gear reducer motor 9 drives the rotating shaft 8 to rotate, causing the flip plate 10 connected to the rotating shaft 8 to flip downwards. When the flip plate 10 is flush with the flip plate 1c, the heating film on the flip plate 10 will slide down onto the flip plate 1c under gravity and be inserted obliquely into the slot formed by the U-shaped guardrail 1c2 and the baffle 1f. Then, the worm gear reducer motor 1b drives the rotating shaft 1a to rotate, causing the flip plate 1c connected to the rotating shaft 1a to be exposed to ultraviolet light. The interior of the UV irradiation cabinet 2 is flipped; once the flipping plate 1c is vertical and the cabinet opening of the UV irradiation cabinet 2 is closed, the heating film will be sealed inside the UV irradiation cabinet 2. At this time, the UV lamp 3 inside the UV irradiation cabinet 2 is turned on to cure the UV ink printed on the heating film. Finally, after the curing process is completed, the UV lamp 3 is turned off, and the worm gear reducer motor 1b drives the rotating shaft 1a in the opposite direction, causing the flipping plate 1c to flip in the opposite direction until one end of the flipping plate 1c extends into the square receiving groove 11 of the base 1. At this time, the heating film that has finished curing will slide down from the flipping plate 1c again and slide into the square receiving groove 11, thereby achieving the automatic feeding effect of the heating film.

[0037] The above-mentioned heating film printing and curing process is fully automated except for material feeding. This not only greatly reduces the labor intensity of manual labor, but also ensures a fast and smooth transition between the two processes of preliminary printing and curing. Furthermore, it can automatically unload the material after completion. Therefore, it is more efficient than traditional pad printing machines and UV light boxes that process heating films separately.
