DETAILED DESCRIPTION

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown, a specific embodiment of the present invention provides a pattern forming device for an artificial quartz plate, including a frame base 1, on which a movable connecting component 2, a feed hopper 3 and a rotary driving mechanism 4 are provided, the movable connecting component 2 is connected to an external moving device, and is used to drive the frame base 1 to move; a rotating disk 11 and a color spraying mechanism 5 are provided at the lower part of the frame base 1, and a cutting device 6 and three discharge hoppers 7 are provided on the rotating disk 11 at intervals along the circumferential direction, and the discharge ends of the three discharge hoppers 7 have different discharge diameters, and the cutting device 6 is used to cut and groove the laid material layer; the rotary driving mechanism 4 is connected to the rotating disk 11, and is used to drive the rotating disk 11 to rotate, so that the corresponding discharge hopper 7 rotates to a position corresponding to the feed hopper 3, and at this time, the discharge hopper 7 is connected to the feed hopper 3; the discharge hopper 7 is used to fill the raw material in the feed hopper 3 into the groove, and the color spraying mechanism 5 is used to color the filler.

[0018] The mobile connection component 2 of the device is adapted to be connected with an external mobile device, and the external mobile device can drive the device or the frame base 1 to move along a specified path to assist in the automatic cutting, slotting, filling and coloring. The external mobile device is preferably a multi-axis manipulator device, but is not limited thereto.

[0019] When slotting is required, the external moving device can control the frame seat 1 to move along the corresponding pattern path in sequence according to the preset filler coloring pattern sequence and pattern path data, so that the cutting device 6 and the discharge hopper 7 on the frame seat 1 move above the material layer. During the slotting movement, the cutting knife 62 of the cutting device 6 moves downward, and the cutting device 6 can cut grooves of different widths on the laid material layer through horizontal movement to form the required pattern grooves. Since different pattern path data correspond to different wide-path slotting operations, that is, grooves of different or same widths and their path data are known in the preset data, they can be arranged in sequence according to the width to obtain the filler coloring pattern sequence, so as to retrieve the corresponding pattern path data according to the sequence relationship to control the cutting device to cut grooves of corresponding widths on the material layer. When filler coloring is required, the external moving device also controls the frame seat 1 to move along the groove direction of the corresponding width in sequence according to the preset filler coloring pattern sequence and pattern path data, such as controlling the frame seat 1 to move along the groove direction of the corresponding width according to the grooves and their path data arranged in sequence according to the width, and at the same time, the rotary drive mechanism 4 rotates the lower hopper of the corresponding discharge diameter to connect with the feed hopper 3 to achieve the corresponding filler preparation work; during the filler movement process, the raw material falls from the lower hopper into the groove, that is, the current discharge diameter of the discharge hopper 7 is slightly greater than or equal to the slot width, and the raw material is discharged from the discharge hopper 7 of the discharge diameter to fully fill the current groove, and at the same time, the color spraying mechanism 5 sprays the material of the required color to the filler to achieve filler coloring. When all slotted grooves have completed the filler coloring work, a pattern of the required shape and color will be formed on the material layer, and the corresponding quartz pattern plate can be obtained by subsequent extrusion molding.

When filling work is required, the rotating disk 11 can be driven to rotate through the rotating drive mechanism 4, so that the corresponding discharge hopper 7 can be rotated to the bottom of the feed hopper 3.
