Description

Technical Field

[0001] This invention belongs to the field of inkjet printing device technology, and particularly relates to a gypsum board marking inkjet printing device and a marking method for the gypsum board marking inkjet printing device. Background Technology

[0002] Gypsum board is a commonly used building material, mainly composed of a gypsum core and a paper surface. It has advantages such as being lightweight, fire-resistant, sound-insulating, and easy to process, and is widely used in the construction and decoration of interior walls and ceilings. Inkjet printing technology using a coding device sprays ink onto the surface of the gypsum board to mark information, which typically includes the production date, batch number, product specifications, and other relevant data, ensuring that the product can be traced back to its production source, facilitating management and quality control.

[0003] When using an inkjet printer, some ink will remain on the surface of the printhead. After prolonged use, the ink will dry and adhere to the printhead surface, affecting the inkjet printer's printing process. Summary of the Invention

[0004] This invention addresses the problem in existing technologies where residual ink on the printhead surface, after drying, affects the coding process of the coding device, and proposes the following technical solution:

[0005] The gypsum board marking and coding device includes:

[0006] The nozzle is connected to an external supply box via a pipeline;

[0007] A cleaning assembly for cleaning residual ink at the bottom of the printhead. The cleaning assembly includes a cleaning brush, a mounting block, a mounting shaft, and a rotating shaft. The mounting shaft is rotatably inserted into the middle of the mounting block, and limit brackets are provided at both ends of the mounting shaft. The cleaning brush is sleeved on the surface of the mounting shaft, and a connector is provided between the rotating shaft and the mounting block.

[0008] The rotating shaft reciprocates in direction A, and the connector maintains the connection between the rotating shaft and the mounting block. Under the restriction of the limit frame, the mounting shaft drives the cleaning brush to reciprocate in direction B to clean the residual ink at the bottom of the printhead.

[0009] As a preferred embodiment of the above technical solution, the connector includes a connecting rod and a plug rod movably inserted into the connecting rod. A spring is fixedly connected between the plug rod and the connecting rod. The connecting rod and the plug rod are respectively fixedly connected to the rotating shaft and the mounting block.

[0010] As a preferred embodiment of the above technical solution, the cleaning assembly further includes a power component, which drives the rotating shaft to reciprocate in direction A. The power component includes a power wheel and a power gear. A reciprocating lead screw is fixedly connected to one side of the power wheel. A spur rack matching the power gear is threaded onto the surface of the reciprocating lead screw. An auxiliary gear is meshed with one side of the power gear. The auxiliary gear is coaxially and fixedly connected to the rotating shaft.

[0011] As a preferred embodiment of the above technical solution, the drive wheel is in contact with the top surface of the plasterboard that it passes over, and the drive wheel rotates as the plasterboard moves.

[0012] As a preferred embodiment of the above technical solution, the cleaning assembly further includes a mounting bracket for mounting a limiting bracket, a rotating shaft, a power gear, and a reciprocating lead screw.

[0013] As a preferred embodiment of the above technical solution, the cleaning brush is cylindrical in shape, and the cleaning brush deforms upon contact with the printhead to absorb and clean residual ink.

[0014] The inkjet printing method for gypsum board marking devices is characterized by comprising the following steps:

[0015] S1, gypsum board conveying;

[0016] The external conveying equipment continuously transports the gypsum board, and the external supply box performs inkjet printing on the gypsum board through the nozzle. The power wheel rotates as the gypsum board moves to provide power to the power unit.

[0017] S2, The rotating shaft reciprocates;

[0018] The power component periodically pushes the rotating shaft to deflect rapidly in direction A and retracts, while the mounting shaft moves along the limit frame, causing the cleaning brush to move in direction B and retract.

[0019] S3. Nozzle cleaning;

[0020] The cleaning brush moves along the bottom surface of the printhead and deforms, absorbing and cleaning the residual ink on the bottom surface of the printhead.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The cleaning brush is quickly moved by the rotation of the rotating shaft. Under the restriction of the limit frame, the cleaning brush moves along the bottom surface of the printhead and deforms, thereby absorbing and cleaning the residual ink on the bottom surface of the printhead. This prevents the ink from drying out for a long time and affecting the ink passage, thus ensuring the coding processing of the coding device.

[0023] 2. By utilizing the contact between the drive wheel and the plasterboard, the drive wheel rotates as the plasterboard moves. This drives the reciprocating screw to rotate and move the rack. The frequency of the drive to the rotating shaft is controlled by varying the length of the reciprocating screw, thus cooperating with the inkjet printer to print on the plasterboard and avoiding any impact on the inkjet printer.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0030] Example

[0031] Figures 1-3 The gypsum board marking and coding device includes:

[0032] Nozzle 10, which is connected to an external supply box via a pipeline;

[0033] The cleaning assembly is used to clean residual ink at the bottom of the printhead 10. The cleaning assembly includes a cleaning brush 21, a mounting block 22, a mounting shaft 23, and a rotating shaft 24. The mounting shaft 23 is rotatably inserted into the middle of the mounting block 22, and limit brackets 25 are provided at both ends of the mounting shaft 23. The cleaning brush 21 is sleeved on the surface of the mounting shaft 23. A connector 26 is provided between the rotating shaft 24 and the mounting block 22.

[0034] The rotating shaft 24 reciprocates in direction A, and the connector 26 maintains the connection between the rotating shaft 24 and the mounting block 22. Under the restriction of the limit frame 25, the mounting shaft 23 drives the cleaning brush 21 to reciprocate in direction B to clean the residual ink at the bottom of the print head 10.

[0035] The connector 26 includes a connecting rod 261 and a plug rod 262 movably inserted into the connecting rod 261. A spring 263 is fixedly connected between the plug rod 262 and the connecting rod 261. The connecting rod 261 and the plug rod 262 are fixedly connected to the rotating shaft 24 and the mounting block 22, respectively.

[0036] When printing inkjet printing on gypsum board, the external conveying equipment continuously conveys the gypsum board. Then, the external supply box prints ink onto the surface of the gypsum board at regular intervals through the printhead 10. The power wheel 271 rotates as the gypsum board moves, providing power to the power component 27, causing the rotating shaft 24 to rotate. The rotating shaft 24 is pushed by the power component 27 to deflect rapidly in direction A. Due to the restriction of the limit frame 25, the mounting shaft 23 moves along the limit frame 25, driving the cleaning soft brush 21 to move in direction B. The mounting block 22 moves accordingly and pulls the plug rod 262 out from the connecting rod 261. The spring 263 is stretched and deformed. The cleaning soft brush 21 moves along the bottom surface of the printhead 10 and deforms. The cleaning soft brush 21 absorbs and cleans the residual ink on the bottom surface of the printhead 10. When the power component 27 resets the rotating shaft 24, the spring 263 resets and pulls the plug rod 262 back into the connecting rod 261, thus resetting the connecting piece 26.

[0037] The cleaning brush 21 is quickly displaced by the rotation of the rotating shaft 24. Under the restriction of the limit frame 25, the cleaning brush 21 moves along the bottom surface of the printhead 10 and deforms, thereby adsorbing and cleaning the residual ink on the bottom surface of the printhead 10, preventing the ink from drying out for a long time and affecting the ink passage, thus ensuring the coding process of the coding device.

[0038] The inkjet printing method for gypsum board marking devices includes the following steps:

[0039] S1, gypsum board conveying;

[0040] The external conveying equipment continuously conveys the gypsum board, and the external supply box performs inkjet printing on the gypsum board through the nozzle 10. The power wheel 271 rotates as the gypsum board moves to provide power to the power unit 27.

[0041] S2, rotating shaft 24 reciprocates;

[0042] The power component 27 periodically pushes the rotating shaft 24 to deflect rapidly in direction A and retract it; the mounting shaft 23 moves along the limit frame 25, driving the cleaning soft brush 21 to move in direction B and retract it.

[0043] S3, nozzle 10 cleaning;

[0044] The cleaning brush 21 moves along the bottom surface of the printhead 10 and deforms, and the cleaning brush 21 absorbs and cleans the residual ink on the bottom surface of the printhead 10.

[0045] Figure 1 , Figure 2 and Figure 3 The cleaning assembly further includes a power component 27, which drives the rotating shaft 24 to reciprocate in direction A. The power component 27 includes a power wheel 271 and a power gear 272. A reciprocating lead screw 273 is fixedly connected to one side of the power wheel 271. A spur rack 274 matching the power gear 272 is threaded onto the surface of the reciprocating lead screw 273. The movement path of the spur rack 274 is restricted by external equipment. An auxiliary gear 275 is meshed with one side of the power gear 272. The auxiliary gear 275 is coaxially fixedly connected to the rotating shaft 24.

[0046] The drive wheel 271 is in contact with the top surface of the plasterboard that it passes over, and the drive wheel 271 rotates as the plasterboard moves.

[0047] When the gypsum board is being transported, the drive wheel 271 and the reciprocating screw 273 rotate as the gypsum board moves. Due to external equipment limitations, the rack 274 moves toward the drive gear 272 and comes into contact with it. The drive gear 272 is pushed to rotate by the rack 274, which in turn drives the drive gear 272 to rotate, and the rotating shaft 24 can then rotate.

[0048] By utilizing the contact between the drive wheel 271 and the gypsum board, the drive wheel 271 rotates as the gypsum board moves. The drive wheel 271 can drive the reciprocating screw 273 to rotate and move the rack 274. Furthermore, by controlling the different lengths of the reciprocating screw 273, the driving frequency of the rotating shaft 24 is controlled, thereby cooperating with the inkjet printer to perform inkjet printing on the gypsum board and avoiding any impact on the inkjet printer.

[0049] Figures 1-3 The cleaning assembly also includes a mounting bracket 28 for mounting a limit bracket 25, a rotating shaft 24, a power gear 272, and a reciprocating lead screw 273.

[0050] The mounting bracket 28 is used to install the limiting bracket 25, the rotating shaft 24, the power gear 272 and the reciprocating screw 273, so as to prevent the cleaning components from shifting and failing to work properly.

[0051] Figures 1-3 In this process, the cleaning soft brush 21 is cylindrical in shape. The cleaning soft brush 21 deforms upon contact with the printhead 10 to absorb and clean residual ink.

[0052] The cleaning brush 21 can deform after contacting the printhead 10, which can increase the friction with the surface of the printhead 10, thereby enhancing the adsorption and cleaning effect on the surface of the printhead 10.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
