[0001] The utility model relates to the field of printing machines, in particular to a negative pressure heating two-in-one seat body for film printing. Background Art
[0002] Decal printing is a printing method in which transferable graphics and texts are printed on a paper or plastic film coated with a glue film (also called a film), and then these graphics and texts are transferred to the surfaces of various materials. Decal printing generally adopts the method of lithography, printing the pattern on the paper surface or plastic film coated with an adhesive layer, and then pasting it on the surface of the object to be decorated during use, and obtaining the decal pattern through transfer. The core of this printing method lies in its transferability, enabling the pattern to be easily transferred from the carrier to the target object. It is not only applicable to the decoration of utensils such as porcelain and glass, but also widely used in the printing of trademarks and patterns in fields such as machine tools, instruments, bicycles, and furniture.
[0003] During the printing process, negative pressure is required to tightly suck the film glue film on the surface of the object. After the current printing seat body generates negative pressure, due to problems such as fewer negative pressure holes and uneven arrangement, the pressure at different positions inside the seat body is uneven, resulting in uneven adsorption force at different positions of the film glue film, affecting the printing quality. And the heating device inside the seat body is usually set on the cover plate, and the preheating and heating effects on the seat body are not good, which needs to be improved.

Specific embodiments
[0023] Embodiment 1, referring to the attached drawings of the specification Figure 1-6 , a negative pressure heating two-in-one base body for film suction printing, comprising a base body 01 and an air suction plate 02. A receiving groove 11 is provided inside the base body 01. The air suction plate 02 is fitted and installed at the bottom of the receiving groove 11. The receiving groove is used to place the items to be printed. A plurality of air suction grooves 21 are arranged in a criss-cross pattern on the bottom surface of the air suction plate 02 in a grid shape. The air suction grooves 21 and the bottom of the receiving groove 11 form a square hole air duct 31. A plurality of small air suction holes 22 are equidistantly arranged along the length direction in the middle of the air suction grooves 21. These small air suction holes are communicated with the square hole air duct 31. Therefore, the respective small air suction holes 22 are in a mutually communicated state; an air suction blind hole 12 is provided in the middle of the side surface of the base body 01. An air joint 13 is installed at the outer end of the air suction blind hole. The air joint 13 is connected to a negative pressure fan. A main air suction hole 14 communicating with the receiving groove 11 is provided at the inner end of the air suction blind hole 12. The main air suction hole corresponds to the position of the air suction groove 21 in the middle of the air suction plate 02.
[0024] As Figure 1 and Figure 2 shown, a layer of high-temperature resistant cloth 61 is covered on the surface of the air suction plate. The high-temperature resistant cloth covers each small air suction hole 22, which is beneficial to further improve the uniformity of air suction through the structural gaps of the cloth itself. Hinge seats 17 are provided at both ends of one side of the base body 01. The hinge seats are used to install the cover plate.
[0025] When the base body 01 is in use, first place the item to be printed on the surface of the air suction plate 02 inside the base body, then cover the film adhesive on the surface of the item. After covering the cover plate, start the negative pressure fan to draw air into the air suction blind hole 12 to generate negative pressure. The negative pressure acts on the interconnected square hole air ducts 31 from the main air suction hole 14, and then a negative pressure is formed on the surface of the air suction plate 02. The film adhesive is sucked tightly on the surface of the item, and then the subsequent heating and printing process is carried out.
[0026] Embodiment 2, referring to the attached drawings of the specification Figure 1-3, 7. On the basis of the first embodiment, in this embodiment, pipe holes are provided in the seat body 01 on both sides of the air suction blind hole 12. A heating pipe 05 is installed in the pipe holes. The wires 51 of the heating pipe extend out of the seat body 01. A long hole 15 is provided on the bottom surface of the seat body. The long hole 15 can reduce the friction force of the heating pipe 05 in the pipe hole, making installation and disassembly more convenient, improving the convenience of maintenance, and appropriately releasing the heat in the pipe hole through the long hole 15 to avoid overheating of the heating pipe. The position of the long hole 15 corresponds to that of the pipe hole. The side surface and the bottom surface of the seat body 01 are both covered with heat insulation plates 62. The heat insulation plates are fixedly connected to the seat body 01 by screws. Legs 16 are provided at the four corners of the bottom surface of the seat body 01, and the legs extend out of the heat insulation plate 62 on the ground. In this embodiment, a heating pipe 05 is provided in the seat body 01 to heat the film adhesive for printing, and the heating pipe 05 is built into the seat body to directly heat the seat body, with little heat loss. Combined with the heat insulation plates 62 around and on the bottom surface of the seat body 01, it can effectively shorten the preheating and heating time of the printing space inside the seat body 01.
[0027] Embodiment Three. Refer to the attached drawings of the specification Figure 1 , 3 , on the basis of the first embodiment, in this embodiment, at least two fixing blocks 04 are provided on the surface of the air suction plate 02. Tapered holes are provided at both ends of the fixing blocks. Countersunk head screws 42 are installed in the tapered holes to fix the fixing blocks 04. An auxiliary hole 41 is provided in the middle of the fixing block 04. The auxiliary hole corresponds to a small air suction hole 22 on the air suction plate 02 up and down. The suction force is transmitted to the auxiliary hole 41 through the small air suction hole 22, so that an adsorption force is generated in the middle of the surface of the fixing block 04. On the one hand, the fixing block 04 is used to support the object to be printed, avoiding deformation of some elastic objects caused by negative pressure and ensuring the flatness of its printing surface. At the same time, it can suck the inner surface of the object through the auxiliary hole 41 to fix the object and avoid displacement of the object caused by negative pressure, further improving the printing effect of the object.
