DETAILED DESCRIPTION

[0017] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0018] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation and be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0019] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0020] The following combination Figures 1 to 7The embodiments of the present application are described.

[0021] When using a single type of dry granule full-sheet fabric, a negative pressure device is required to remove any unadhered dry granules. This suction also removes dust from the air, contaminating the dry granules. Large quantities of dry granules circulating in the pipes can also cause rapid wear and tear, leading to contamination. Furthermore, when recovering large quantities of dry granules, the negative pressure pipes must maintain sufficient negative pressure and air speed, requiring the use of a high-power fan (230), which increases energy consumption.

[0022] Secondly, when multiple dry particles are required for decoration, the existing equipment needs to be equipped with multiple sets of inkjet machines and dry particle machines in combination, and equipped with multiple negative pressure suction devices 20. This not only increases the equipment investment due to the high cost of the inkjet machine itself, but also requires the length of the glaze line to be extended to accommodate these devices, ultimately resulting in a complex overall equipment structure and inconvenient operation.

[0023] Based on this, the present application provides a dry particle distribution device, which includes a frame, a discharging mechanism 10, a discharging control component 110 and a rotating component 120; The discharging mechanism 10 is provided on the frame and has a feeding end 1011 and a discharging gap 1022. Dry particles can be fed from the feeding end 1011. The discharge control assembly 110 includes a plurality of control cylinders 111 and blocking plates 112. The plurality of control cylinders 111 are sequentially arranged along the length of the discharge mechanism 10. The control cylinders 111 are provided with a plurality of air inlet channels, each of which is provided with a solenoid valve. Each control cylinder 111 is connected to a blocking plate 112. The solenoid valve controls the cylinders 111 to drive the connected blocking plates 112, thereby driving the blocking plates 112 to open or close specific areas or corresponding portions of the discharge gap 1022. The rotating assembly 120 is rotatably connected to the discharge mechanism 10 to adjust its discharge angle. When the blocking plate 112 is opened, the dry particles fall through the gap, and the discharge speed is adjusted according to the angle of the hopper base 102. The closed area is blocked by the blocking plate 112, preventing other dry particles from falling.

[0024] Therefore, by setting up multiple independent control cylinders 111 to drive the blocking plate 112, the corresponding area of ​​the discharge gap 1022 can be opened or closed, thereby accurately controlling the drop area of ​​the dry particles in the width direction of the cloth; at the same time, the rotating component 120 is used to adjust the overall inclination angle of the discharge mechanism 10, change the discharge speed and throwing trajectory of the dry particles, and realize fixed-point adjustment of the cloth amount and cloth position, and further reduce the waste or pollution of dry particles by reducing the cloth amount of dry particles.

[0025] Specifically, the discharge mechanism 10 includes a dry granule hopper 101 and a hopper base 102. The dry granule hopper 101 is mounted on a frame. The hopper base 102 is disposed below the dry granule hopper 101 and is rotatably connected to a rotating assembly 120. A feed end 1011 is disposed at the top of the dry granule hopper 101, and a discharge end is disposed at the bottom of the dry granule hopper 101. The hopper base 102 is provided with a feed trough 1021, the opening of which is connected to the discharge end. A discharge gap 1022 is disposed at the bottom of the hopper base 102 and is connected to the feed trough 1021. Dry granules fall from the dry granule hopper 101 into the feed trough 1021 of the hopper base 102, are guided to the bottom of the hopper 102 through the feed trough 1021, and fall through the discharge gap 1022.

[0026] Optionally, a discharge sealing plate 103 is fixed to the bottom of the hopper base 102 , and a gate plate 104 is fixed to the side thereof, and a discharge gap 1022 is formed between the discharge sealing plate 103 and the gate plate 104 .

[0027] In some embodiments, the rotating assembly 120 includes a support plate 121 and a driving device. There are two support plates 121, and the two support plates 121 are fixed on the frame and arranged on both sides of the hopper base 102. A rotating shaft 122 and a protrusion 123 are fixed on one side of the hopper base 102. Each support plate 121 is provided with a fulcrum hole 124 and a limiting groove 125. The protrusion 123 is slidably arranged in the limiting groove 125. The rotating shaft 122 passes through the fulcrum hole 124 and is connected to the driving device. The driving device drives the hopper base 102 to rotate with the rotating shaft 122 as the axis.

[0028] Exemplarily, the driving device is a motor, which drives the rotating shaft 122 to rotate. The hopper base 102 rotates around the rotating shaft 122 as the axis, and the protrusion 123 slides along the limiting groove 125 to limit the rotation angle, thereby adjusting the discharge angle.

[0029] Optionally, the inclination angle ranges from 35° to 70°. Exemplarily, the limiting groove 125 is an arc-shaped groove with an arc of 35°, and the limiting groove 125 is arranged opposite to the fulcrum hole 124 .

[0030] In some embodiments, a connecting base 105 is fixed to the hopper base 102. The connecting base 105 is provided with a plurality of limiting inserts 106 along its length. The blocking piece 112 is provided with limiting slots 1121 that engage with the limiting inserts 106. After the blocking piece 112 is engaged with the limiting inserts 106 on the connecting base 105 through the limiting slots 1121, when the control cylinder 111 pushes the blocking piece 112, the limiting inserts 106 restrict the blocking piece 112 from vertically rising and falling, preventing the blocking piece 112 from horizontally shifting, ensuring the accuracy of opening and closing the discharge gap 1022, and preventing the blocking piece 112 from shifting due to vibration or pressure.

[0031] The present application also provides a distribution assembly comprising any of the above dry particle distribution devices, a negative pressure suction device 20, and a conveyor. The negative pressure suction device 20 is used to absorb loose dry particles that are not attached to the conveyor. Multiple dry particle distribution devices and multiple negative pressure suction devices 20 are alternately arranged along the conveying direction of the conveyor. The multiple dry particle distribution devices are arranged along the conveying direction of the conveyor and sequentially distribute dry particles at fixed points. The negative pressure suction device 20 is located between adjacent distribution devices to absorb loose dry particles after the previous distribution.

[0032] Specifically, a conveyor transports the bricks to be distributed. The first dry granule distribution device distributes the granules in a designated area on the baseplate. When the baseplate moves to the negative pressure device, the unattached granules are sucked away. The second dry granule distribution device then distributes the granules in a new area, and the process repeats. This allows for the separate recycling of different types of dry granules by alternating the dry granule distribution devices, preventing cross-contamination of the dry granule materials.

[0033] In some embodiments, each negative pressure suction device 20 includes a suction nozzle 210, a fan 230, and a cyclone separator 220. The suction nozzle 210 is positioned above the conveyor and between adjacent dry particle distribution devices. The cyclone separator 220 is connected to and communicates with the suction nozzle 210 and the fan 230, respectively. In other words, the negative pressure suction device 20 only requires alternating placement of the suction nozzles 210 and dry particle distribution devices; the remaining components can be centralized. Centralized suction can be used, with multiple fans 230 controlled by variable frequency according to the distribution volume of each section.

[0034] Optionally, the cyclone separation barrel 220 includes a barrel 221 and a cone 222 that are interconnected. The barrel 221 has an inlet 2211 and an outlet. The inlet is connected to the suction nozzle 210, and the outlet is connected to the air inlet of the fan 230. The cone 222 is conical in shape and has a discharge port 223 at the bottom for discharging dry particles. The airflow containing dry particles enters the barrel 221 through the inlet 2211. The airflow rotates within the barrel 221, and the dry particles are thrown toward the barrel wall. The conical cone 222 can guide the dry particles to gather and fall toward the center, improving separation efficiency. The dry particles then slide along the cone 222 to the discharge port 223. The purified air is discharged from the top outlet, thereby avoiding dust pollution. The dry particles can be recycled for secondary use.

[0035] Furthermore, a dust bag is installed at the exhaust port of fan 230 to filter out dust. After cyclonic separation, the air still contains a small amount of fine dust, which is filtered through the dust bag before being discharged. The bag has a porous filter layer that allows air to pass through but absorbs fine dust, achieving secondary purification.

[0036] The present application also provides a method for controlling a cloth assembly, which is used to control the operation of the cloth assembly. The cloth assembly further includes an inkjet printer and a coding machine. The cloth control method includes the following steps: The dry particle area layer data is obtained and converted into a cloth instruction file in a preset format; specifically, the part of the inkjet design drawing that needs to spray dry particles is extracted to the layer, the dry particle area layer data in the inkjet design drawing is obtained, and the layer data is converted into a CSV format cloth instruction file.

[0037] According to the fabric instruction file in a preset format, corresponding positioning marks are extracted to obtain associated positioning marks.

[0038] Based on the associated positioning marks, the inkjet machine and the coding machine are controlled to spray and print the bricks to obtain the brick positioning marks; Specifically, an inkjet printer is used to position and spray glue on the surface of the brick, and a coding machine is used to print marks on specific positions of the brick.

[0039] Collect the positioning mark image of the brick and generate real-time control signals; Specifically, the positioning mark image of the brick is collected in real time by a camera device, and is decoded to generate a real-time control signal.

[0040] In response to the real-time control signal, the control cylinder 111 group of at least one dry particle distribution channel is controlled to perform opening and closing actions, thereby delivering dry particles to a specific area at a fixed point; that is, in actual configuration, multiple distribution devices form different distribution channels, and in response to the generated real-time control signal, the solenoid valves on different distribution channels are controlled to operate to control the control cylinder 111 of at least one dry particle distribution device to perform opening and closing actions.

[0041] The negative pressure suction device 20 is started to suck different dry particles; specifically, each negative pressure suction device 20 sucks the dry particles on the brick surface that are not adhered to the glue into an independent cyclone separation barrel for recycling.

[0042] Furthermore, before the control cylinder 111 group of at least one dry particle distribution channel is controlled to perform an opening and closing action in response to a real-time control signal, thereby delivering dry particles to a specific area, the method further includes: According to the distribution instruction file, the opening of the gate 104 of the distribution device and the inclination angle of the rotating component 120 are adjusted to control the amount of dry particle distribution; specifically, the opening size of the gate 104 or the inclination angle of the rotating component can be pre-set, or adjusted according to the corresponding distribution requirements, so that the size of the discharge gap is limited by the gate height, and the distribution angle is adjusted by the rotating component to control the distribution amount.

[0043] Therefore, for the glue applied at specific points by inkjet printers, using a dry particle distribution device capable of targeted distribution can significantly reduce the total amount of dry particle distribution. This significantly reduces the amount of dry particles that are not adhered to the glue when passing through the negative pressure suction device, which not only reduces pipe wear but also reduces dust contamination. This in turn reduces fan power and optimizes energy consumption.

[0044] In practical applications involving a wide range of dry granule distribution, a single inkjet printer is required to perform the targeted glue spraying, with multiple sets of dry granule distribution equipment and negative pressure suction devices arranged alternately. The negative pressure suction device only requires alternating nozzles with the dry granule distribution equipment, while all other components can be centrally arranged. This allows for the separate recovery of various dry granules, effectively preventing secondary contamination caused by mixed dry granules. It also significantly shortens the glazing line, simplifies the equipment layout, and improves operational convenience.
