[0024] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] As Figure 1 , Figure 2 and Figure 3 shown, a dry granule digital printing device includes a frame 100, a material storage mechanism, and a gate control assembly 300. The material storage mechanism includes a plurality of material boxes 200, and the material boxes 200 are installed on the frame 100. A plurality of cloth outlets 210 are provided at the bottom of the material box 200. The cloth outlets 210 are arranged in a longitudinal column, and there is an interval between adjacent cloth outlets 210. The gate control assembly 300 includes a plurality of gates 310 and a control mechanism 320. The gates 310 and the control mechanism 320 are arranged along the y-axis direction ( Figure 1 , Figure 2 and Figure 3 only shows a part of the gate control assembly 300), and the number of gates 310 corresponds to the cloth outlets 210 one by one. A control mechanism 320 controls a gate 310 to move below a corresponding cloth outlet 210 at the bottom of the material box 200. A through hole 311 is provided on the gate 310. Normally, the through hole 311 and the cloth outlet 210 are misaligned with each other, so as to block the cloth outlet 210 by using the gate 310. When the gate 310 moves to a position where the through hole 311 and the cloth outlet 210 are communicated, the dry granules in the material box 200 fall through the cloth outlet 210 and the through hole 311 to achieve cloth laying.

[0026] As Figure 3 shown, when viewed from the bottom direction, the plane space at the bottom of the material storage mechanism is defined as an x-y axis coordinate system, and the long side direction of the material box 200 is the y-axis direction. The following takes two material boxes 200 as an example for illustration. Two material boxes 200 are arranged along the x-axis direction. Each material box 200 is provided with two columns of cloth outlets 210 arranged along the y-axis direction. There is a certain interval between the cloth outlets 210 in the same column, and the adjacent three columns of cloth outlets 210 are arranged according to the following rules (as Figure 4As shown in the figure: The first fabric outlet 210a in the third column is spatially located below and tangent to the first fabric outlet 210b in the first column. The first fabric outlet 210c in the second column is spatially located below and tangent to the first fabric outlet 210a in the third column. The second fabric outlet 210d in the first column is spatially located below and tangent to the first fabric outlet 210c in the second column. They are arranged in sequence in the above-mentioned manner. It is equivalent to that the interval between two adjacent fabric outlets 210 in the same column is the size of two fabric outlets 210 in the other two columns. The size of the through hole 311 of the gate 310 is the same as the size of the fabric outlet 210. It is equivalent to that when the dry particles fall through the fabric outlet 210 and the through hole 311, their fabric ranges are tangent to each other along the y-axis direction. The tile moves along the x-axis direction under the digital printing device. According to the specific pattern of the tile, each corresponding gate 310 is driven by each control mechanism 320 to control the opening and closing of each fabric outlet 210. With a tangent fabric range along the y-axis, only by controlling the number of fabric outlets 210 distributed, as well as the sizes of the fabric outlet 210 and the through hole 311, can all ranges of the tile be covered for fabric, and it can be ensured that accurate fabric can be carried out according to the pattern position of the tile, and the fineness of the pattern laid out is very high. The position of the fabric outlet 210 is set in this way. In addition to achieving the main purpose of fabric accuracy, another main purpose is to solve the problem that the gate 310 and the control mechanism 320 have minimum size limitations in the mechanical structure. For example, in order to meet the pattern accuracy standard, the fabric outlet 210 or the through hole 311 needs to be controlled within a range of 2.3 mm. However, the minimum mechanical size of a conventional control mechanism 320 can only reach 7 mm. Then there will inevitably be a spacing of about 4.7 mm between adjacent fabric outlets 210. In order to make up for the problem that the spacing range cannot be fabric, the above-mentioned structural method of setting multiple columns of fabric outlets 210 is used to solve the above problem.

[0027] In some specific embodiments of the present invention, a chute 220 is provided at the interval between two adjacent fabric outlets 210 in the same column. Protruding edges 312 that can be clamped in the chute 220 are provided on both sides of the gate 310. As Figure 5 and Figure 6 shown, there are chutes 220 on both sides of a fabric outlet 210. The gate 310 is in a plate-like structure. The protruding edges 312 on both sides of the gate 310 are clamped in the chute 220. The upper end surface of the gate 310 is attached to the bottom surface of the material box 200. When the control mechanism 320 drives the gate 310 to move, the inner wall of the protruding edge 312 is attached to the side wall of the chute 220 and slides along the chute 220. That is, the chute 220 has a guiding and limiting effect on the gate 310, ensuring that the fabric outlet 210 and the through hole 311 can be centered and aligned, and ensuring the blanking effect.

[0028] Further, one end of the sliding groove 220 is open and the other end is closed. The closed end of the sliding groove 220 limits the moving stroke of the convex edge 312. The convex edge 312 of the gate 310 slides into the sliding groove 220 from the open end of the sliding groove 220. When the gate 310 moves until one end of the convex edge 312 abuts against the closed end of the sliding groove 220, the cloth outlet 210 and the through hole 311 are communicated to perform positioning.

[0029] In some specific embodiments of the present invention, two rows of cloth outlets 210 are provided at the bottom of each material box 200, and a gate control assembly 300 corresponding to the cloth outlet 210 is provided on both sides of each material box 200. The gate control assembly 300 is installed by using the space on the long side of both sides of the material box 200 to make full use of the space.

[0030] In some specific embodiments of the present invention, the gate control assembly 300 is pneumatically driven, the control mechanism 320 is a solenoid valve, and each gate 310 is pneumatically connected by controlling the solenoid valve so that each gate 310 moves. The quantity and position distribution of the cloth outlets 210 are set according to the mechanical dimensions of the solenoid valve.

[0031] The above-mentioned gate control assembly 300 can select the structure of an integrated pneumatic device in Chinese Patent CN201821346681.7.
