[0002] Most existing sheet metal printing equipment is a two-dimensional oscillating device with X and Y axes. To achieve two-dimensional oscillation, it is necessary to have motion guides in at least two directions of movement. For example, it is necessary to adjust the synchronization and coordination of at least two motors, which requires a high degree of equipment motion synchronization and coordination. At the same time, the printing equipment basically only has inkjet coloring function and does not have the function of performing pre-processing on the sheet metal before inkjet printing. Therefore, the sheet metal needs to be pre-processed on other processing equipment before inkjet printing, which results in high equipment costs, occupies a lot of factory space, and has low production efficiency.

[0019] A textured pattern processing device for artificial stone slabs includes: an X-axis slab conveying device (1), a Y-axis moving device (2), a pre-processing mechanism (3), and an inkjet printing mechanism (4); The Y-axis moving device (2) includes: a Y-axis frame (21); The conveying end of the X-axis slab conveying device (1) passes between the two ends of the Y-axis frame (21) and is used to convey artificial stone slabs (7) along the X-axis direction. The pretreatment processing mechanism (3) and the inkjet printing mechanism (4) are movably mounted on the Y-axis frame (21); the pretreatment processing mechanism (3) moves from one end of the Y-axis frame (21) to above the conveying end of the X-axis sheet material conveying device (1), and the pretreatment processing mechanism (3) is used to perform corona pretreatment on the artificial stone sheet (7); the inkjet printing mechanism (4) moves from the other end of the Y-axis frame (21) to above the conveying end of the X-axis sheet material conveying device (1), and the inkjet printing mechanism (4) is used to perform inkjet printing on the pretreated area of the artificial stone sheet (7).
[0020] This solution provides an artificial stone slab texture pattern processing equipment, which transports artificial stone slabs (7) through an X-axis slab conveying device (1), and controls the pre-treatment processing mechanism (3) or inkjet printing mechanism (4) to be positioned directly above or away from the artificial stone slabs (7). This reduces the requirements for motion synchronization and coordination between the pre-treatment processing mechanism (3) and the inkjet printing mechanism (4), thereby simplifying the structure of the equipment and solving the problem of high equipment cost and low production efficiency caused by the pre-treatment and inkjet printing of artificial stone slabs (7) being performed step by step in different equipment.
[0021] Specifically, an artificial stone slab (7) is placed at the conveying end of the X-axis slab conveying device (1), and the artificial stone slab (7) is conveyed towards the X-axis direction at the conveying end of the X-axis slab conveying device (1). The artificial stone slab (7) is conveyed to the Y-axis moving device (2). The pre-processing mechanism (3) and the inkjet printing mechanism (4) are movably mounted on the Y-axis frame (21) in a known manner. In this way, the pre-processing mechanism (3) and the inkjet printing mechanism (4) can move independently on the Y-axis frame (21) and can be used as needed. Move to the conveying end of the conveying device (1) to process the artificial stone slab (7); the pre-treatment processing mechanism (3) is used to pre-treat the artificial stone slab (7) with corona, mainly before the artificial stone slab (7) is printed, in order to make the surface of the artificial stone slab (7) have stronger adhesion, and pre-treat with corona; the inkjet printing mechanism (4) is used to inkjet print and cure the artificial stone slab (7), mainly outputting ink, powder, pigment and other media to the artificial stone slab (7) and curing the media to surface dry. The X-axis sheet material conveying device (1), the pre-processing mechanism (3), and the inkjet printing mechanism (4) can be linked for processing. In the initial state, the pre-processing mechanism (3) and the inkjet printing mechanism (4) are located at different ends of the Y-axis frame (21). When the artificial stone sheet (7) is conveyed from the conveying end of the X-axis sheet material conveying device (1) to the bottom of the Y-axis moving device (2), the unprocessed area of the artificial stone sheet (7) is located directly below the Y-axis frame (21). The inkjet printing mechanism (4) moves in advance or moves synchronously to one end of the Y-axis frame (21), and the pre-processing mechanism (3) moves from one end of the Y-axis frame (21) to the unprocessed area of the artificial stone sheet (7). The pre-processing mechanism (3) performs corona pre-processing on the artificial stone sheet (7). After the pre-processing mechanism (3) completes the pre-processing, the pre-processing mechanism (3) resets and moves to one end of the Y-axis frame (21). At this time, the inkjet printing mechanism (4) is called. 4) Move the inkjet printing mechanism (4) from one end of the Y-axis frame (21) to the unprocessed area of the artificial stone slab (7); the inkjet printing mechanism (4) performs inkjet printing on the artificial stone slab (7). After the inkjet printing mechanism (4) completes inkjet printing on the pre-processed area, the inkjet printing mechanism (4) resets and moves to one end of the Y-axis frame (21). At this time, the X-axis slab conveying device (1) is called. The conveying end of the X-axis slab conveying device (1) drives the artificial stone slab (7) forward one unit. The unprocessed area of the artificial stone slab (7) moves to below the Y-axis frame (21). The X-axis slab conveying device (1), the Y-axis moving device (2), the pre-processing mechanism (3) and the inkjet printing mechanism (4) repeat the above steps until the unprocessed area of the artificial stone slab (7) is completed with inkjet printing. Subsequently, depending on the processing needs, the artificial stone slab (7) can be subjected to a curing process to cure the ink on the surface of the artificial stone slab (7).Thus, this solution simplifies the equipment structure, significantly reducing the space required for pretreatment and inkjet printing processes.
[0022] The X-axis sheet material conveying device (1) is a known mechanism that drives the sheet material to move, such as a conveyor belt device, a conveyor roller device, a moving trolley, a robot arm, a combination of gears and chains, etc. It is sufficient to directly or indirectly drive the sheet material to move. The movement of the pre-processing mechanism (3) and the inkjet printing mechanism (4) on the Y-axis frame (21) can be achieved by a known mechanism that drives the movement, such as a cylinder, a hydraulic cylinder, a linear motor, a combination of a motor and a lead screw, a robot arm, a combination of gears and racks, a combination of gears and chains, etc. It is sufficient to achieve movement on the Y-axis frame (21).
[0023] Optimally, the pretreatment processing mechanism (3) includes: a corona frame (31), a corona lifting seat (32), a corona head (33), a corona thickness measuring device (34), and a corona Z-axis lifting driver (35); The corona frame (31) is movably mounted on the Y-axis frame (21) and moves from one end of the Y-axis frame (21) to above the conveying end of the X-axis plate conveying device (1); the corona lifting seat (32) is movably mounted on the corona frame (31); the corona head (33) is mounted on the corona lifting seat (32); the corona thickness measuring device (34) is connected to the corona frame (31) and is communicatively connected to the corona Z-axis lifting driver (35) for detecting the local corona thickness of the artificial stone slab (7) below the corona lifting seat (32); the corona Z-axis lifting driver (35) is mounted on the corona frame (31) and its output end is connected to the corona lifting seat (32) for driving the corona lifting seat (32) to move up and down according to the local corona thickness.
[0024] The corona frame (31) moves on the Y-axis frame (21), thereby driving the corona lifting seat (32), corona head (33), corona thickness measuring device (34), and corona Z-axis lifting drive (35) to move as a whole on the Y-axis frame (21); the corona lifting seat (32) can be lifted relative to the corona frame (31); the corona head (33) is set on the corona lifting seat (32) for corona pretreatment of the artificial stone slab (7) below. It uses high frequency and high voltage to corona discharge on the surface to be treated, thereby generating low temperature plasma. These ions penetrate into the surface of the substrate by electric shock and penetration, destroying its molecular structure, thereby oxidizing and polarizing the surface molecules to be treated. Ion electric shock erodes the surface, thereby increasing the adhesion of the substrate surface; the corona thickness measuring device (34) is set on the corona lifting seat (32) for detecting the local corona thickness of the artificial stone slab (7) below the corona lifting seat (32); the corona thickness measuring device (34) As the corona machine frame (31) moves along the Y-axis, the corona thickness measuring device (34) can detect the local corona thickness of the artificial stone slab (7) below and feed back the local corona thickness to the corona Z-axis lifting driver (35). The corona Z-axis lifting driver (35) can drive the corona lifting seat (32) to move up and down according to the local corona thickness, so that the corona head (33) is raised and lowered to the designated position, so that the distance between the output end of the corona head (33) and the surface of the artificial stone slab (7) is adjusted to within the preset range. On the one hand, this can avoid the corona head (33) from hitting the uneven surface of the artificial stone slab (7) when moving in the Y direction. On the other hand, it can make the corona head (33) be in the best pre-processing position, so that each unprocessed area of the artificial stone slab (7) is kept at a specific distance from the output end of the corona head (33), so that the corona environment is kept consistent and the problem of color appearing in the texture pattern of the artificial stone slab is reduced during the corona pre-processing process.
[0025] The corona lift base (32) can be lifted and installed on the corona machine frame (31) and can be connected by conventional sliders and slide rails.
[0026] Optimally, the inkjet printing mechanism (4) includes: an inkjet base (41), an inkjet printhead (42), and a UV curing lamp (43); The inkjet printhead (42) and UV curing lamp (43) are respectively connected to the inkjet base (41); the inkjet base (41) is movably mounted on the Y-axis frame (21), driving the inkjet printhead (42) and UV curing lamp (43) to move; the inkjet base (41) moves from one end of the Y-axis frame (21) to above the conveying end of the X-axis sheet material conveying device (1); The inkjet printhead (42) is used to print inkjet prints on the artificial stone slab (7), and the UV curing lamp (43) is used to UV cure the artificial stone slab (7) in the area after inkjet printing.
[0027] The inkjet printer base (41) can move along the Y-axis frame (21); the inkjet printhead (42) can output ink to the artificial stone slab (7); the inkjet printing mechanism (4) presets specific patterns and textures; the inkjet printhead (42) outputs ink to the artificial stone slab (7) according to preset parameters; the UV curing lamp (43) is also located on the inkjet printer base (41); the UV curing lamp (43) can UV cure the ink output by the inkjet printhead (42); the movement of the inkjet printer base (41) can drive the UV curing lamp (43) to move synchronously, thereby driving the UV curing lamp (43) to the position after the inkjet printhead (42) prints; the UV curing lamp (43) can cure the ink.
[0028] Alternatively, the inkjet printing mechanism (4) may further include: a printing lifting seat (44), a printing thickness measuring device (45), and a printing Z-axis lifting driver (46); The printing lifting base (44) is movably and vertically connected to the inkjet printer base (41), the inkjet printhead (42) is mounted on the printing lifting base (44), and the UV curing lamp (43) is located on the printing lifting base (44). The printing thickness measuring device (45) is connected to the printing lifting base (44) and is used to detect the local printing thickness of the artificial stone slab (7) below the printing lifting base (44). The printing thickness measuring device (45) is communicatively connected to the printing Z-axis lifting driver (46). The printing Z-axis lifting driver (46) is mounted on the inkjet printer base (41), and the output end of the printing Z-axis lifting driver (46) is connected to the printing lifting base (44) to drive the printing lifting base (44) to move vertically and vertically according to the local printing thickness, so as to adjust the distance between the inkjet printhead (42) and the artificial stone slab (7).
[0029] The printing lifting platform (44) is flexibly mounted on the inkjet printer base (41). The printing Z-axis lifting driver (46) is mounted on the inkjet printer base (41). The printing Z-axis lifting driver (46) drives the printing lifting platform (44) to rise and fall on the inkjet printer base (41). The inkjet printhead (42) is mounted on the printing lifting platform (44). The rising and falling movement of the printing lifting platform (44) drives the printing thickness measuring device (45) and the UV curing lamp (43) to rise and fall synchronously. The inkjet printer base (41) moves on the Y-axis frame (21), thereby driving the inkjet printhead (42), the printing thickness measuring device (45), and the UV curing lamp (43) to move horizontally synchronously to the unprocessed area of the artificial stone slab (7). The printing thickness measuring device (45) can detect the local printing thickness of the artificial stone slab (7) below and feed back the local printing thickness to the printing Z-axis lifting driver (46). The actuator (46) can drive the printing lifting seat (44) to move up and down according to the local thickness of the printing, so that the inkjet print head (42) is raised and lowered to the designated position, so that the distance between the output end of the inkjet print head (42) and the surface of the artificial stone slab (7) is adjusted to a preset range. On the one hand, it can avoid the inkjet print head (42) from hitting the uneven surface of the artificial stone slab (7) when moving in the Y direction. On the other hand, it can keep the inkjet print head (42) at the optimal inkjet height position based on the different thicknesses below, so that the unprocessed areas of the artificial stone slab (7) and the output end of the inkjet print head (42) maintain a preset inkjet distance, so that the physical and chemical properties of the ink output are consistent with the environment, and the ink in multiple unprocessed areas remains uniform. This solves the problem of large color when the inkjet print head (42) outputs ink on the uneven surface of the artificial stone slab (7).
[0030] The printing lifter (44) is movable and height-adjustable to the inkjet printer base (41), and the connection can be achieved through conventional sliders and slide rails.
[0031] Optimally, the printing lifting seat (44) has the printing thickness measuring device (45) on the side away from the corona thickness measuring device (34), and the corona frame (31) has the corona thickness measuring device (34) on the side away from the printing thickness measuring device (45); the printing thickness measuring device (45) and the corona thickness measuring device (34) are communicatively connected.
[0032] The printing thickness measuring device (45) is located on the side of the printing lifting platform (44) away from the corona thickness measuring device (34), and the printing thickness measuring device (45) is located on the side of the corona frame (31) away from the printing thickness measuring device (45). Thus, when the pre-processing mechanism (3) and the inkjet printing mechanism (4) are integrated as a whole, the printing thickness measuring device (45) and the corona thickness measuring device (34) are equivalent to being located on both sides of the Y-axis of the whole. In the initial state, the corona thickness measuring device (34) and the corona head (33) move synchronously along the Y-axis. For each unit of movement of the corona head (33), the corona thickness measuring device (34) detects the thickness of the stone slab below and obtains multiple units of movement in the Y-axis direction. The pre-processing Y-axis driver (24) records the horizontal position of each corona local thickness in the Y-axis direction until the pre-processing mechanism (3) completes the corona treatment and is placed in the stationary section (222) on one side; based on the communication connection between the printing thickness measuring device (45) and the corona thickness measuring device (34), the corona thickness measuring device (34) sends the corona local thickness to the printing thickness measuring device (45), and the pre-processing Y-axis driver (24) sends the corresponding movement unit to the printing Y-axis driver (25); at this time, the printing Y-axis driver (25) drives the inkjet printing mechanism (4) to move from the stationary section (222) on the other side to the processing section (221); the inkjet printing mechanism (4) can Printing begins at the end of the processing section (221) closest to the pre-processing mechanism (3), which is equivalent to printing along the movement path of the pre-processing mechanism (3); the inkjet printing mechanism (4) can also begin printing at the end of the processing section (221) furthest from the pre-processing mechanism (3), which is equivalent to printing along the opposite movement path of the pre-processing mechanism (3); after the inkjet printing mechanism (4) moves to the position where the pre-processing mechanism (3) has been corona-electrode and prints ink, the printing Y-axis driver (25) drives the inkjet printing mechanism (4) to move horizontally along the Y-axis by one unit. Since the position of the corona has recorded the local thickness of the corona, during the Y-axis movement, the printing Z-axis lifting driver (46) can... The height of the printing lifting seat (44) is coarsely adjusted according to the local corona thickness. After the Y-axis movement, the Z-axis lifting driver (46) then finely adjusts the height of the printing lifting seat (44) according to the local printing thickness obtained in real time by the printing thickness measuring device (45). In this way, the inkjet printing mechanism (4) can be coarsely adjusted according to the local corona thickness during the Y-axis movement, so as to shorten the time for the inkjet printing mechanism (4) to adjust the height after reaching the next moving unit, improve the processing efficiency of the texture pattern of artificial stone slabs (7), and solve the problem that the existing digital inkjet printer cannot react in time to adjust the height of the digital inkjet head due to the excessively fast movement speed, resulting in poor printing effect and damage to the digital inkjet head.
[0033] The printing thickness measuring device (45) and the corona thickness measuring device (34) mainly use known non-contact measuring devices to measure the thickness of artificial stone slabs (7), such as ultrasonic thickness measuring devices, laser thickness measuring devices, capacitive sensing devices, eddy current sensors, etc., as long as the local thickness measurement of artificial stone slabs (7) is achieved.
[0034] Alternatively, the inkjet printing mechanism (4) may further include: an anti-collision sensor (47); The anti-collision sensor (47) is communicatively connected to the printing Y-axis driver (25); the anti-collision sensor (47) is disposed on the side of the inkjet base (41) in the Y-axis direction, and the anti-collision sensor (47) is used to control the conveyor end of the printing Y-axis driver (25) to stop moving.
[0035] The anti-collision sensor (47) can be set on one side of the inkjet printer base (41) or on both sides of the inkjet printer base (41). The anti-collision sensor (47) is mainly set on the side of the inkjet printer base (41) in the Y-axis direction, such as the front side and / or the rear side in the Y-axis direction. When the inkjet printer base (41) moves along the Y-axis direction, if the anti-collision sensor (47) is horizontally close to or in contact with other objects other than the inkjet printing mechanism (4), the anti-collision sensor (47) can control the conveying end of the printing Y-axis driver (25) to stop moving, thereby preventing the inkjet printer base (41) from continuing to move forward, thereby avoiding the inkjet printing mechanism (4) from colliding with other objects, thereby ensuring the movement stability of the inkjet printing mechanism (4).
[0036] The anti-collision sensing device (47) is a known mechanism with anti-collision function, such as an anti-collision micro switch, a laser anti-collision device, an infrared anti-collision device, an ultrasonic anti-collision device, an electromagnetic wave anti-collision device, a vibration / tilt sensor device, etc.
[0037] Alternatively, the inkjet printing mechanism (4) may further include: a side frame (48); The side frame (48) is installed on the side of the printing lifting seat (44) in the Y-axis direction. The side frame (48) surrounds the side of the printing lifting seat (44) to form a post-processing frame opening (481). The UV curing lamp (43) is located at the post-processing frame opening (481). The printing lifting seat (44) and the post-processing frame opening (481) are positioned sequentially along the Y-axis in the area of the artificial stone slab (7) after corona pretreatment.
[0038] This scheme divides the inkjet printing mechanism (4) horizontally into different functional areas: a printing lift (44) with an inkjet printhead (42) and a post-processing frame (481) with a UV curing lamp (43). When the inkjet printing mechanism (4) moves one unit, its printing lift (44) first stays in the pre-treated area of the artificial stone slab (7), and the inkjet printhead (42) performs inkjet printing on the corona-treated area. After that, the inkjet printing mechanism (4) continues to move one unit, and the post-processing frame (481) stays in the inkjet-printed area, and the UV curing lamp (43) of the post-processing frame (481) performs UV curing on the ink in the inkjet-printed area. In this way, the printing lift (44) and the post-processing frame (481) simultaneously perform inkjet printing and curing on two adjacent areas of the artificial stone slab (7) along the Y-axis, which greatly improves the processing efficiency of the texture pattern of the artificial stone slab (7).

[0040] The inkjet printer base (41) has an upper seat (411) above the inkjet printhead (42). The CNC board (5) is installed on the upper seat (411) and moves along the Y-axis with the inkjet printer base (41). A middle seat (412) is left between the upper seat (411) and the printing lifter (44). The middle seat (412) is used to set the ink cartridge (6). The ink cartridge (6) can be used to provide ink to the inkjet printhead (42) below, so as to provide ink replenishment function for the inkjet printhead (42) after long-term operation. In this way, the upper seat (411), the middle seat (412) and the inkjet printhead (42) are arranged in a stacked structure. The layers do not interfere with each other. The inkjet printing mechanism (4), ink cartridge (6) and CNC board (5) moving along the Y-axis are arranged in a three-in-one stacked structure, which can make full use of the longitudinal space of the non-working area.

The pre-processing mechanism (3) and the inkjet printing mechanism (4) are movably disposed on the Y-axis moving track (22). The Y-axis moving track (22) has a processing section (221) in the area directly above the conveying end of the X-axis sheet material conveying device (1). The two ends of the processing section (221) are respectively provided with stationary sections (222). The output end of the pre-processing Y-axis driver (24) is connected to the pre-processing mechanism (3) and is used to drive the pre-processing mechanism (3) to move on the Y-axis moving track (22); the output end of the printing Y-axis driver (25) is connected to the inkjet printing mechanism (4) and is used to drive the inkjet printing mechanism (4) to move on the Y-axis moving track (22); The X-axis sheet material conveying device (1), the pre-processing Y-axis driver (24), and the printing Y-axis driver (25) are communicatively connected; when the pre-processing Y-axis driver (24) drives the pre-processing mechanism (3) to move in the processing section (221), the printing Y-axis driver (25) causes the inkjet printing mechanism (4) to stay in the stationary section (222); when the printing Y-axis driver (25) drives the inkjet printing mechanism (4) to move in the processing section (221), the pre-processing Y-axis driver (24) causes the pre-processing mechanism (3) to stay in the stationary section (222).

Above the left and right sides of the conveying end of the shaft plate conveying device (1); the pre-processing Y-axis driver (24) can be set on the Y-axis frame (21) or the pre-processing mechanism (3) to drive the pre-processing mechanism (3) to move on the Y-axis moving track (22); the printing Y-axis driver (25) can be set on the Y-axis frame (21) or the inkjet printing mechanism (4) to drive the inkjet printing mechanism (4) to move on the Y-axis moving track (22); in this way, the pre-processing mechanism (3) and the inkjet printing mechanism (4) can move independently on the Y-axis.

[0043] The X-axis slab conveying device (1), the pre-processing Y-axis driver (24), and the printing Y-axis driver (25) are connected in communication and can be processed in conjunction with each other. When the artificial stone slab (7) is conveyed from the conveying end of the X-axis slab conveying device (1) to the area below the Y-axis moving device (2), the unprocessed area of the artificial stone slab (7) is located directly below the processing section (221). The printing Y-axis driver (25) pre-drives the inkjet printing mechanism (4) to move to the stationary section (222) on one side. The pre-processing Y-axis driver (24) drives the pre-processing mechanism (3) to move along the Y-axis moving track (22), so that the pre-processing mechanism (3) performs corona pre-processing on the artificial stone slab (7) in the Y-axis direction. After the pre-processing mechanism (3) completes the pre-processing, the pre-processing Y-axis driver (24) drives the pre-processing mechanism (3) to move to the stationary section on the other side. (222) At this time, the printing Y-axis driver (25) is called.
