Description

Technical Field

[0001] This utility model relates to the field of building ceramics production equipment, and in particular to a dehumidification and moisture-proof device for an inkjet printer. Background Technology

[0002] To enhance the decorative richness of ceramic tiles, after glazing the tile surface, an inkjet printer can typically be used to print ink onto the glazed surface, creating the desired patterns and textures. Some existing inkjet printers have a print head fixed in the printing channel. As the tile passes beneath the print head, the print head precisely jets ink onto the tile surface according to a preset pattern and program, thus achieving the printing process.

[0003] However, the glaze used in the previous glazing step contains moisture, and the brick blank itself has a certain temperature due to the drying process. During the inkjet printing process, the moisture in the glaze will evaporate due to the temperature of the brick blank and rise into the printing channel. In the printing channel, it will liquefy upon cooling and form water droplets, making the circuit board in the printing channel very susceptible to malfunction due to moisture. When large-scale production is required, moisture accumulates even faster, the frequency of machine failures increases, seriously affects the normal operation of the circuit, and may even lead to equipment damage, reduced production efficiency, and increased production costs, which is not conducive to large-scale production. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a dehumidification and moisture-proof device for inkjet printers, thereby solving the problem that moisture from the surface of brick blanks entering the printing channel can easily cause internal circuit board malfunctions due to moisture.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A dehumidification and moisture-proof device for an inkjet printer includes a dehumidification and cooling mechanism and pipes;

[0007] The air inlet of the pipe is connected to the output end of the dehumidification and cooling mechanism, and the air outlet of the pipe is located inside the printing channel of the inkjet printer. Below the printing channel of the inkjet printer is a brick conveying device.

[0008] The dehumidification and cooling mechanism includes a fan and a dehumidification and cooling module. The dehumidification and cooling module, the fan, and the pipe are connected in sequence, and the air inlet of the dehumidification and cooling module is connected to the atmosphere. The dehumidification and cooling module is used to dehumidify and cool the atmosphere to obtain dry cold air. The fan is used to transport the dry cold air processed by the dehumidification and cooling module to the printing channel.

[0009] Preferably, the inkjet printer is provided with a plurality of printing channels;

[0010] The pipeline includes a main pipeline and several branch pipelines. The air inlet of the main pipeline is connected to the output end of the fan, and the air outlet of the main pipeline is connected to several branch pipelines. The number of branch pipelines is equal to the number of printing channels, and one pipeline is connected to one printing channel.

[0011] Furthermore, the diameter of the main pipeline is larger than the diameter of the branch pipeline, and the diameters of several branch pipelines are equal.

[0012] Preferably, the dehumidification and cooling module is a compressor dehumidification device.

[0013] Preferably, the dehumidification and cooling module is a semiconductor dehumidification device.

[0014] Preferably, both the dehumidification and cooling mechanism and the pipe are located above the inkjet printer.

[0017] The technical solution provided by this utility model can include the following beneficial effects:

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] A dehumidification and moisture-proof device for an inkjet printer includes a dehumidification and cooling mechanism and a pipe 3;

[0026] The air inlet of the pipe 3 is connected to the output end of the dehumidification and cooling mechanism, and the air outlet of the pipe 3 is located inside the printing channel 41 of the inkjet printer 4. Below the printing channel 41 of the inkjet printer 4 is the brick blank conveying device 43.

[0027] The dehumidification and cooling mechanism includes a fan 2 and a dehumidification and cooling module 1. The dehumidification and cooling module 1, the fan 2, and the pipe 3 are connected in sequence, and the air inlet of the dehumidification and cooling module 1 is connected to the atmosphere. The dehumidification and cooling module 1 is used to dehumidify and cool the atmosphere to obtain dry cold air. The fan 2 is used to transport the dry cold air processed by the dehumidification and cooling module 1 to the printing channel 41.

[0028] To address the problems existing in the prior art, this utility model proposes a dehumidification and moisture-proof device for an inkjet printer, specifically for an inkjet printer 4 equipped with a printing channel 41 and a brick conveying device 43 for conveying brick blanks located below the printing channel 41. Specifically, the dehumidification and moisture-proof device of this utility model includes a dehumidification and cooling mechanism and a pipe 3, such as... Figure 1As shown, the dehumidification and cooling module 1, fan 2, and duct 3 are connected in sequence. The air outlet of the duct 3 faces the printing channel 41 from top to bottom. The dehumidification and cooling module 1 dehumidifies and cools the outside air to obtain dry cold air. The fan 2 draws the obtained dry cold air and transports it through the duct 3. The dry cold air is discharged from the air outlet of the duct 3 and continuously flows from top to bottom through the printing channel 41. After the brick blank is glazed, during the printing process of the brick blank using the inkjet printer 4, the air outlet of the duct 3 continuously outputs dry cold air, which flows from top to bottom through the printing channel 41. At this time, the flowing dry cold air has the characteristics of low water vapor content, low temperature, and directional flow. The brick blank passes under the printing channel 41 under the brick blank conveying device 43. The water vapor formed by the glaze due to the temperature of the brick blank itself comes into contact with the dry cold air flowing from top to bottom during the rising process. It is carried by the dry cold air and driven out of the printing channel 41 according to the original flow direction of the dry cold air. Even during its ascent, moisture is affected by dry, cold air and blown out of the device before reaching the printing channel 41, maintaining the dryness of the printing channel 41. This reduces the likelihood of malfunctions caused by moisture affecting the control boards inside the printing channel 41, ensuring normal circuit operation, reducing the frequency of inkjet printer 41 failures, extending the equipment's lifespan, and minimizing downtime due to printing channel 41 malfunctions. Consequently, production efficiency is improved, maintenance costs are reduced, and the problem of moisture entering the printing channel 41 from the brick surface, which easily causes internal circuit board malfunctions due to moisture, is solved.

[0029] In addition, the air outlet of the pipe 3 is located inside the printing channel 41. Dry, cold air passes through the pipe 3 from top to bottom through the printing channel 41, precisely controlling the drying position instead of large-area cooling and dehumidification, thus reducing energy consumption.

[0030] Preferably, the inkjet printer 4 is provided with a plurality of the printing channels 41;

[0031] The pipe 3 includes a main pipe 31 and several branch pipes 32. The air inlet of the main pipe 31 is connected to the output end of the fan 2. The air outlet of the main pipe 31 is connected to several branch pipes 32. The number of branch pipes 32 is equal to the number of printing channels 41, and one branch pipe 32 is connected to one printing channel 41.

[0032] Specifically, existing inkjet printers, in order to obtain tiles with rich colors, need to have multiple printing channels 41 to perform inkjet printing operations on different color cards. The pipe 3 consists of a main pipe 31 and branch pipes 32. The air inlet of the main pipe 31 is connected to the output end of the fan 2. The fan 2 draws the dry cold air obtained after being processed by the dehumidification and cooling module 1 to the main pipe 31. The dry cold air passes through several printing channels 41 from top to bottom through the branch pipes 32, realizing the drying treatment of multiple printing channels 41 and achieving efficient dehumidification.

[0033] It is worth noting that the number of printing channels 41 is determined according to production needs, and the number of branch pipes 32 is equal to the number of printing channels 41, ensuring that each printing channel 41 is dried.

[0034] Furthermore, the diameter of the main pipe 31 is larger than the diameter of the branch pipe 32, and the diameters of the branch pipes 32 are equal.

[0035] Thus, during the delivery of dry and cold air, the larger diameter of the main pipe 31 can provide a larger flow area, ensuring sufficient flow to supply each of the branch pipes 32, ensuring that several printing channels 41 have continuous dry and cold air passing through, and ensuring that all printing channels 41 are not affected by the water vapor formed by the brick blanks.

[0036] Furthermore, the branch pipes 32 have the same diameter, ensuring that each printing channel 41 receives the same amount of dry, cold air, which helps maintain the pressure balance within the pipes 3.

[0037] Preferably, the dehumidification and cooling module 1 is a compressor dehumidification device.

[0038] Specifically, the compressor dehumidification device uses its internal compressor to drive the internal refrigerant circulation, and the water vapor in the air is condensed through the low-temperature surface of its internal evaporator. It can reduce the humidity of the air to the required range in a relatively short time, obtaining dry air, while at the same time lowering the air temperature, quickly obtaining the required dry and cold air.

[0039] Preferably, the dehumidification and cooling module 1 is a semiconductor dehumidification device.

[0040] Specifically, the semiconductor dehumidifier utilizes its internal semiconductor thermoelectric cooling chip to achieve dehumidification and cooling functions, obtaining the required dry and cold air. Furthermore, the semiconductor dehumidifier can control the temperature of the dry and cold air by adjusting the magnitude and direction of the current, obtaining dry and cold air at the required temperature according to the working environment requirements of the inkjet printer 4.

[0041] Preferably, the dehumidification and cooling mechanism and the pipe 3 are both located above the inkjet printer 4.

[0042] During the operation of the inkjet printer 4, some moisture generated by the brick blanks is blown out of the machine by dry and cold air, participating in the formation of hot and humid air. The dehumidification and cooling mechanism and the pipe 3 are located above the inkjet printer 4, which can capture the hot and humid air in time, perform dehumidification and cooling treatment, and improve air handling efficiency.

[0043] Furthermore, placing the dehumidification and cooling mechanism and the pipe 3 above the inkjet printer 4 facilitates the delivery of dry and cold air, reduces the resistance caused by the length of the pipe 3, and effectively reduces the energy consumption of the fan 2.

[0044] Preferably, the upper surface of the housing of the inkjet printer 4 is provided with a mounting port 42, and the mounting port 42 is located above the printing channel 41, and the air outlet of the pipe 3 is fitted into the mounting port 42.

[0045] In this way, the dry, cold air flowing in the pipe 3 can be accurately passed through the printing channel 41 from top to bottom, ensuring that the rising water vapor is carried away.

[0046] Preferably, the fan 2 is disposed on the side of the dehumidification and cooling module 1.

[0047] Specifically, the fan 2 is located on the side of the dehumidification and cooling module 1, which can more evenly draw the dry cold air processed by the dehumidification and cooling module 1, so that the dry cold air entering the pipe 3 is more evenly distributed and can be more evenly diffused to all corners of the printing channel 41, ensuring the drying effect.

[0048] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
