Digital printing printers integrate mechanical, computer and electronic information technology. Digital printing printers are usually used to make large-format printed fabrics. Among them, during the spraying process of digital printing printers, the flatness of the printing medium will directly affect the printing effect.

The printer paper leveling environmental protection device not only realizes the elastic pressure-covering type efficient drying of the paper leveling device during paper transportation, facilitates the convenient control and adjustment type contact leveling of paper, but also improves the efficiency of the paper leveling device, and facilitates the filtering and purification of harmful gases generated by the paper. However, the device cannot level and limit the printing medium during the printing process. Utility Model Content

[0004] In order to limit the edge of the printing medium in real time to prevent it from folding, and to adjust it in real time according to the width of the printing medium, the technical solution adopted by the utility model is: a magnetic paper pressing mechanism, including a paper pressing board base, and a pair of slides installed on the side walls of the printing platform;

[0005] The slideway is magnetically adsorbed with a magnet, and both ends of the press paper substrate are bent downward to form a fixed bending plate for connecting the magnet.

[0006] A paper pressing strip is connected to one side of the paper pressing paper substrate. The paper pressing strip is suspended in the air, and a space for the edge of the printing medium to move is formed between the lower surface of the paper pressing strip and the upper surface of the printing platform.

[0007] Based on the above, in order to facilitate the printing medium to enter under the paper pressing bar, the length of the paper pressing bar is greater than the length of the paper pressing board substrate.

[0008] Based on the above, in order to facilitate firm fixation, a fixing block is further connected to the inner side of the magnet, and the fixed bending plate is detachably clamped between the magnet and the fixing block.

[0009] Based on the above, in order to ensure smooth movement, the slide is an inverted L-shaped slide, and a pair of the inverted L-shaped slides are symmetrically installed on the side walls of the printing platform and are set at the same height.

[0010] Based on the above, the width of the paper pressing strip is smaller than the width of the paper pressing paper substrate.

[0011] Based on the above, in order to expand the space for the edge of the printing medium to move, the upper surface of the paper pressing strip is higher than the upper surface of the paper pressing board base, that is, the paper pressing strip is connected to the paper pressing board base through an inclined plate.

[0012] The utility model also provides an industrial printer, which is equipped with the magnetic suction paper pressing mechanism.

[0013] The utility model has substantial features and progress compared with the prior art. Specifically, the magnetic paper pressing mechanism and industrial printer provided by the utility model install slides on both sides of the printing platform of the industrial printer, install a pair of magnets on the slides, and then install a pair of paper pressing mechanisms for smoothing the edges of both sides of the printing medium on the magnets. In this way, the side edges of the printing medium can be smoothed in real time during the paper feeding process of the printer, effectively preventing wrinkles, folds, etc. from occurring on the edges of the printing medium.

[0014] At the same time, the magnetic paper pressing mechanism uses magnets as fixing parts to adsorb the paper pressing board base onto the printing platform. There is a magnetic adsorption force, which limits the free swinging range of the printing medium along its width direction, effectively preventing the paper pressing strip from being squeezed open due to the left and right shaking of the printing medium.

[0015] Furthermore, by slidingly arranging a pair of paperboard pressing mechanisms on the printing platform, it is convenient to adjust according to different widths of the printing medium, and the operation is convenient.

[0016] Furthermore, the fixing is performed by magnet adsorption, which ensures that the press paper has a certain installation stability, and at the same time, it is convenient for sliding adjustment, and the steps of removing the fixing screws are omitted. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0023] Example 1

[0024] This embodiment provides a magnetic suction paper pressing mechanism, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a paperboard base 6 and a pair of slideways 2 installed on the side walls of the printing platform 1.

[0025] A magnet 5 is magnetically adsorbed on the slideway 2 , and both ends of the paperboard base 6 are bent downward to form a fixed bending plate 8 for connecting the magnet 5 .

[0026] A paper pressing strip 7 is connected to one side of the paper pressing board base 6, and the paper pressing strip 7 is suspended, and a space for the edge of the printing medium to move is formed between the lower surface of the paper pressing strip 7 and the upper surface of the printing platform 1. That is, the paper pressing board base is adsorbed on the printing platform by a magnet as a fixing part, and due to the existence of magnetic adsorption force, the magnetic adsorption force will limit the free swinging range of the printing medium along its width direction, effectively preventing the situation where the paper pressing strip is squeezed open due to the left and right shaking of the printing medium.

[0027] In this embodiment, in order to facilitate firm fixation, a fixing block 4 is further connected to the inner side of the magnet 5, and the fixing bending plate 8 is detachably clamped between the magnet 5 and the fixing block 4. An exhaust fan 9 is also provided at the bottom of the printing platform, so that the printing platform forms an adsorption platform, further increasing the flatness of the printing medium.

[0028] When in use, two magnetic paper pressing mechanisms can be installed at both ends of the printing platform and arranged relative to each other, so that the side of the printing medium can be flattened in real time during the paper feeding process of the printer, effectively preventing wrinkles and folds on the edge of the printing medium.

[0029] Example 2

[0030] This embodiment provides a magnetic paper pressing mechanism, which is mainly different from the embodiment 1 in that: in this embodiment, in order to facilitate the printing medium to enter under the paper pressing strip 7, the length of the paper pressing strip 7 is greater than the length of the paper pressing paper substrate 6. The width of the paper pressing strip 7 is less than the width of the paper pressing paper substrate 6. In order to expand the space for the edge of the printing medium to travel, the upper surface of the paper pressing strip 7 is higher than the upper surface of the paper pressing paper substrate 6.

[0031] Example 3

[0032] This embodiment provides a magnetic paper pressing mechanism, which is mainly different from the embodiment 1 in that, in this embodiment: in order to move smoothly, the slide 2 is an inverted L-shaped slide, and a pair of the inverted L-shaped slides are symmetrically installed on the side walls of the printing platform 1 and are arranged at the same height. Specifically, the inverted L-shaped slide can be made of angle iron. A ruler 3 is also provided on the printing platform 1.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
