Description

Technical Field

[0001] The present invention belongs to the field of ceramic production, relates to inkjet technology, and specifically is a ceramic inkjet printing device for ceramic production. Background Art

[0002] The working principle of a ceramic inkjet printing device is mainly to control the ink in the ink cartridge to form an image on the ceramic surface; when the print head moves according to a predetermined pattern, the ink is sprayed on the ceramic surface in the form of tiny droplets; after these droplets dry on the ceramic surface, the required image or pattern is formed.

[0003] Referring to the patent name: A ceramic inkjet printing device for ceramic production (Patent Publication No.: CN221718158U), by turning on the motor to drive the first reciprocating lead screw and the second reciprocating lead screw to rotate, the two first reciprocating lead screws are fixed to each other and can rotate simultaneously. The first reciprocating lead screw drives the clamping plates sleeved on the outer wall with threads to reciprocate towards the middle. In this way, the two clamping plates will clamp the ceramic conveyed on the conveyor belt, changing the skewed conveying posture of the ceramic into a vertical conveying posture, which is convenient for subsequent printing; the rotation of the second reciprocating lead screw causes the reciprocating slider to drive the cleaning brush head to reciprocate, realizing the cleaning before printing.

[0004] However, when implementing the above technical solutions, there are the following problems: the movable area of the cleaning brush head in the above device is constant and difficult to change. When cleaning a single ceramic product, it is necessary to wait for its reciprocating movement and clean the ceramic product twice. The cleaning time is fixed. If the ceramic product to be inkjet has a relatively small size, its cleaning process only requires a small reciprocating process. However, due to the fixed reciprocating path, it will relatively take a long time, extending the overall processing and inkjet time of the ceramic product.

[0005] Therefore, the present invention proposes a ceramic inkjet printing device for ceramic production. Summary of the Invention

A cleaning rod 1 is rotatably connected inside the cleaning rack, and a cleaning brush is slidably arranged on the surface of the cleaning rod 1.

A threaded rod is rotatably connected inside the centering rack, and two centering rods are threadedly connected to the surface of the threaded rod. The cleaning rack, the dual-axis motor, the centering rack, and the inkjet printer main body are arranged in sequence. Synchronous wheels and synchronous belts are arranged between the dual-axis motor and the cleaning rod 1 and the threaded rod respectively to realize the rotational adjustment of the cleaning rod 1 and the threaded rod. And a sliding conveyor belt is arranged inside the inkjet printer base;

[0033] An adjustment mechanism is arranged between the cleaning rod 1 and the cleaning brush. The adjustment mechanism includes:

[0034] A number of driving rings 21, the driving rings 21 are all detachably arranged on the surface of the cleaning rod 1. Cross grooves 22 are formed on the surface of the driving rings 21. The projection of the cross grooves 22 is funnel-shaped. A driving ball is fixedly connected to the surface of the cleaning brush, and the driving ball is adapted to the cross grooves 22. A fixing component is arranged between adjacent driving rings 21;

[0035] It should be noted that after a number of the driving rings 21 are sequentially attached, the cross grooves 22 will be combined into two thread groove shapes with the same pitch and opposite helix directions. Through the adaptation of the cross grooves 22 and the driving balls, the cleaning brush can reciprocally slide on the surface of the driving rings 21;

[0036] The fixing component includes a clamping groove 23 formed on the surface of the driving ring 21. The cross section of the clamping groove 23 is T-shaped. Insertion rods 24 are all slidably connected inside the driving rings 21. The length of the insertion rods 24 is equal to the length of the driving rings 21. A clamping rod 25 is rotatably connected inside the insertion rods 24. An eccentric wheel is slidably connected to the end of the clamping rod 25. A clamping shaft 26 is slidably connected inside the insertion rods 24. The clamping shaft 26 is slidably connected to the eccentric wheel. The clamping shaft 26 and the insertion rods 24 are adapted to the clamping groove 23;

[0037] A limiting component is arranged between the driving ring 21 and the cleaning rod 1 to make the surfaces of the two parallel;

[0038] In the actual application process of the ceramic inkjet printing device for ceramic production, the rod for sliding the cleaning brush is split into a number of driving rings 21. Cross grooves 22 are provided on the surface of the driving ring 21. The reciprocating movement of the cleaning brush is realized through the contact between the cross grooves 22 and the driving balls on the surface of the cleaning brush. Furthermore, a certain number of driving rings 21 can be selectively combined according to the size of the ceramic product. The stroke distance of the reciprocating sliding of the cleaning brush is limited by the combined length of the driving rings 21, which is convenient for adjusting the cleaning time according to ceramic products of different sizes and quickly completing the cleaning before ceramic inkjet. The connection between several driving rings 21 is realized through a rotating eccentric wheel and a sliding locking shaft 26, which is convenient for positioning two driving rings 21 according to the positions of the insertion rod 24 and the locking groove 23, ensuring that the cross grooves 22 on their surfaces can fit and the movement of the cleaning brush is unobstructed;

[0042] In a further embodiment, the connecting component includes a connecting rod 36 rotatably arranged inside the limiting ring 31, the end of the connecting rod 36 is threadedly connected to the connecting groove, and the length of the connecting rod 36 is equal to the sum of the widths of the limiting ring 31 and the eccentric wheel; through grooves 37 are formed on the surfaces of the positioning blocks 32, and the through grooves 37 are adapted to the connecting rod 36; by providing the connecting rod 36 passing through the limiting ring 31, a structure capable of being adapted to the locking groove 23 can exist on the surface of the limiting ring 31, and the positions of the driving ring 21 and the limiting ring 31 can be further fixed through the locking groove 23 on the surface of the driving ring 21, so that the centers of the driving ring 21 and the cleaning rod 1 can be ensured to be on the same horizontal line;

[0043] In a further embodiment, the limiting component includes a threaded groove formed on the surface of the driving ring 21, the projection of the intersection position of the cross grooves 22 covers the projection of the threaded groove, a limiting rod is threadedly connected inside the threaded groove, and the end of the limiting rod away from the cleaning rod 1 is recessed inside the threaded groove; the limiting rod can provide a supporting force between the cleaning rod 1 and the driving ring 21, and at the same time, the limiting rod does not prevent the formation of the cross grooves 22 and the sliding of the cleaning brush;

[0044] In some specific embodiments, a moving groove is formed on the surface of the eccentric wheel, a moving column is fixedly connected to one end of the locking shaft 26 close to the eccentric wheel, the moving column is adapted to the moving groove, and a moving spring is fixedly connected between the moving column and the insertion rod 24; the moving spring can quickly reset the locking shaft 26 and can reduce the force required for the eccentric wheel to reset, facilitating quick disassembly;

[0045] In some specific embodiments, a moving block 41 is detachably connected to the surface of the cleaning rod 1, two moving shafts 42 are slidably connected to the surface of the cleaning rod 1, a moving spring 43 is fixedly connected between the two moving shafts 42, a moving groove is formed on the surface of the moving block 41, and the moving groove is adapted to the moving shaft 42; through the moving shaft 42 and the moving groove, the cleaning rod 1 can be disassembled and the insertion block can be driven to slide;

[0046] The working principle of the present invention:

[0047] Before using the ceramic inkjet printer, first adjust the number of components of the driving ring 21 according to the size of the ceramic to be cleaned to change the sliding stroke of the cleaning brush. Press the abutting shaft 42 to make the abutting shaft 42 disengage from the abutting groove, remove the abutting block 41, then first slide in a limiting ring 31, and then slide in the driving ring 21 according to the position of the connecting rod 36 on the surface of the limiting ring 31. The next driving ring 21 is placed according to the positions of the clamping groove 23 and the insertion rod 24, so that the insertion rod 24 is inserted into the clamping groove 23. Then rotate the clamping rod 25 to make the eccentric wheel slide, drive the clamping shaft 26 to slide, and the clamping shaft 26 contacts the clamping groove 23 to limit the position between the two driving rings 21. Slide in the appropriate number of driving rings 21 in the same operation, and at the same time ensure that the cross grooves 22 on the surface of a single driving ring 21 are in contact with the driving balls. Then put in the limiting ring 31, and then rotate the worm 35 inside the limiting ring 31. The rotation of the worm 35 causes the worm gear 34 to rotate, and then the positioning block 32 slides. When the positioning block 32 contacts the cleaning rod 1, stop rotating the worm 35. The limiting ring 31 will drive the driving ring 21 to move, and then screw in the limiting rod according to the position of the thread groove on the surface of the corresponding driving ring 21 to make the limiting rod contact the cleaning rod 1.
