Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate purification, in particular to an online code spraying system and method of a plate purification production line. BACKGROUND

[0002] Composite plates need to use wood fiberboard or shaving board and plywood as base materials, and are hot-pressed with impregnated paper. In the manufacturing process, tri-aldehyde glue containing formaldehyde is widely used. After the plate manufacturing is completed, the composite plate contains a large amount of formaldehyde, which will gradually release and harm human health if used directly. After the manufacturing is completed, the composite plate usually needs to be treated by high-temperature de-aldehyde. The conventional processing scheme usually uses a conveying belt to send the plate into a drying kiln, and then sends it out of the drying kiln after the purification is completed for other process treatment. However, the conventional processing scheme has a series of problems such as uneven heating of both sides of the plate, easy bending and deformation of the plate, incomplete formaldehyde release, low degree of automation of the entire purification process, and low purification efficiency.

[0003] To solve the problems of uneven heating of the plate and low degree of automation in the conventional plate purification route, the current solution is to use a plate transportation frame to clamp and transport the plate, so that the plate is maintained in a vertical state during transportation. The plate is continuously sent into and out of the drying cabin, the conditioning cabin, and the spraying cabin in a rhythmic manner for a series of plate purification treatments, and the plate purification process is completed.

[0004] After the plate is treated by each process, it will be subjected to code spraying before being packaged for delivery, so that the C-end consumer can check and confirm the plate purification status, material quality, environmental protection level, and other information. The code spraying module on the existing production line usually uses a code spraying machine. The two-dimensional code sequence is placed in the code spraying machine in advance. At the code spraying moment, the two-dimensional code and the code spraying time provided by the code spraying machine are sequentially sprayed onto the material. However, the current code spraying method can only record the code spraying time of the code spraying machine, and does not record the time after the plate material is treated by the entire purification process. The sprayed code is a two-dimensional code sequence pre-stored in the database and sequentially sprayed, which causes the current code spraying machine to be unable to bind the material code. For the current multi-stage treatment of various types and grades of plates, the existing code spraying machine cannot achieve online real-time code spraying according to the actual situation of the material.

[0005] Under the above background technology, the inventor designs an online code spraying system and method of a plate purification production line to solve the above problems, and thus proposes the present application. SUMMARY

[0056] Meanwhile, it should be understood that the sizes of the various parts shown in the drawings are not drawn in accordance with the actual proportional relationship for the convenience of description.

[0057] In addition, the description of the well-known structures, functions and configurations can be omitted for the sake of clarity and conciseness. Those skilled in the art will recognize that various changes and modifications of the examples described herein can be made without departing from the spirit and scope of the disclosure.

[0058] The technologies, methods and devices known to those skilled in the relevant art can not be discussed in detail, but should be considered as part of the authorized description where appropriate.

[0059] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the example embodiments can have different values.

[0060] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0061] Example 1:

[0062] like Figures 1 to 4 As shown, an online inkjet printing system for a board purification production line includes a board purification production line, an inkjet printing actuator installed at the discharge end of the board purification production line, and a central controller, a data acquisition module, and an inkjet printing actuator, all of which are connected to a communication module.

[0063] The acquisition module includes acquisition unit A for acquiring the time T before the board enters the board purification production line, and acquisition units B, C and D for acquiring the operating mode data of the board purification production line.

[0064] The central controller is used to generate the inkjet printing execution time and inkjet printing sequence table based on the time T it acquires and the operating mode data of the board purification production line;

[0065] The communication module is used to forward time T and operating mode data to the central controller, and to forward the real-time code in the inkjet sequence table to the inkjet execution mechanism at the inkjet execution time.

[0066] The inkjet printing actuator is used to receive inkjet printing information from the communication module and perform inkjet printing actions.

[0067] The design concept of this embodiment is to utilize a data acquisition module, a communication module, a central controller, and a coding execution mechanism to collect real-time data on the time T before the board enters the processing stage, as well as the processing mode data of the board purification production line, and forward this data to the central controller. After processing by the central controller, a coding execution time and a coding sequence table are generated. At the coding execution time, the real-time code in the coding sequence table is forwarded to the coding execution mechanism to perform the coding action. This enables the board purification system and the coding execution mechanism to be linked and bound online and in real time, forming a material-code binding effect, rather than the existing stand-alone coding where the coding machine and the production line are independent of each other. This effectively solves the problems of existing technologies.

[0071] The time T when the digital code printing sequence table is acquired by the central controller and the plate purification production line operation mode are generated. The real-time code is divided into a two-dimensional code and a digital code, which facilitates the consumer C-end customer to intuitively observe the plate production time, plate category, environmental protection information and other information.

[0072] Referring to Figure 2 In the embodiment, the two-dimensional code printing sequence table includes a two-dimensional code sequence field, and its corresponding:

[0076] The central controller is used to acquire and process the high-temperature cabin operation mode, the spraying cabin operation mode, and the tempering cabin operation mode information and fill them into the two-dimensional code printing sequence table.

[0077] In the embodiment, the high-temperature cabin processing time, the tempering cabin processing time, and the spraying cabin processing time are all indirectly obtained plate estimated processing times, and the high-temperature cabin processing time data, the tempering cabin processing time data, and the spraying cabin processing time data can be obtained by calculation or according to the high-temperature cabin operation mode, the tempering cabin operation mode, and the spraying cabin operation mode.

[0080] The acquisition unit B is used to acquire the heating power of the first heating structure and the rotation speed of the plate drying rack in the high-temperature cabin. The length distance of the high-temperature cabin is the distance between its feeding port and discharging port. In the case where the rotation speed of the plate drying rack is determined, the linear speed of the transmission chain driving the rotation of the plate drying rack can be obtained, and thus the plate residence processing time in the high-temperature cabin can be obtained, i.e., the processing time data under the high-temperature cabin time field can be obtained.

[0081] According to the acquired heating power of the first heating structure, the corresponding heating temperature in the high-temperature cabin can be obtained, which is a prior art and will not be described here.

[0085] The collection unit C is used to collect the heating power of the second heating structure, the rotation speed of the airing plate rack in the tempering cabin, and the humidifying power of the humidifying structure. In the embodiment, the processing time data of the plate in the high-temperature cabin can be obtained by the same principle and process, and the temperature data in the tempering cabin can be obtained. By obtaining the humidifying power of the humidifying structure, the processing humidity data in the tempering cabin can be obtained.

[0086] In the embodiment, referring to Figure 2 As shown, the spraying cabin operation mode field further includes a medicament spraying amount field;

[0087] The spraying cabin operation module includes a medicament adding structure for spraying medicament to the plate;

[0088] The collection unit D is used to collect the medicament adding power of the medicament adding structure and the linear speed of the conveying belt in the spraying cabin.

By collecting the atomizing power of the atomizing sheet, the medicament spraying amount data of the spraying cabin can be obtained. In the embodiment, the linear speed of the conveying belt is a fixed value, and the time length of the plate from the high-temperature cabin to the tempering cabin can be obtained according to the distance between the discharge port of the high-temperature cabin and the inlet port of the tempering cabin. The spraying time length can also be obtained according to the distance between the inlet port and the discharge port of the spraying cabin and the linear speed of the conveying belt.

[0089] In the embodiment, referring to Figure 2 As shown and Figure 3 As shown, the high-temperature cabin operation mode field, the spraying cabin operation mode field and the tempering cabin operation mode field all include a processing time length field;

[0090] The digital code spraying code sequence table includes a digital code sequence field, and its corresponding:

[0091] An estimated spraying code time field;

[0092] The central controller is used to obtain and process the processing time data under the processing time field in the two-dimensional code inkjet code sequence list, superimposes the processing time T obtained by the central controller to generate the estimated inkjet code time data S of the board, and fills the digital code inkjet code sequence list.

[0093] In this embodiment, the estimated inkjet code time data S under the estimated inkjet code time field is the time for the inkjet mechanism to perform inkjet, and is also part of the data information content in the digital code.

[0094] In this embodiment, the digital code contains the category data information of the board, the environmental protection level data information, and the information of the estimated inkjet code time data S,

[0095] In this embodiment, the digital code inkjet code sequence list further includes an environmental protection level field and a board category field. Figure 3

[0096] The central controller is used to generate a digital code according to the environmental protection level data and the board category data under the environmental protection level field and the board category field, and the estimated inkjet code time data S, and bind the digital code with the corresponding two-dimensional code inkjet code sequence list. In some embodiments, the digital code can also include other information such as board function.

[0097] In this embodiment, the board category data and the environmental protection level data can be imported into the digital code inkjet code sequence list, or can be judged by real-time data acquisition. Both are prior art, and will not be described here. In some embodiments, the high-temperature cabin running module, the spraying cabin running module, and the conditioning cabin running module adjust the running mode according to the board category data and the environmental protection level data.

[0100] The acquisition unit C acquires data within the period of (T+Sa, T+Sb);
