Description

Technical Field

[0001] This utility model relates to the field of digital printing drying technology, and in particular to an energy-saving dryer. Background Technology

[0002] With the rapid development of digital printing technology, its application areas have expanded from traditional document printing to multiple industries such as textiles, packaging materials, advertising printing, and building materials decoration. In the digital printing process, after the ink is precisely sprayed onto the surface of the substrate through the printhead, it needs to undergo drying treatment to achieve curing, in order to ensure the color stability, adhesion, and abrasion resistance of the printed pattern. Therefore, the drying device has become one of the core components of digital printing equipment.

[0003] Current digital printer dryers generally adopt the mature approach of "resistance heating plus air blowing." While this achieves basic drying functions, it suffers from high energy consumption, uneven temperature distribution, heat leakage, and high maintenance requirements due to open-loop heat circulation, inefficient heating elements, insufficient frame rigidity, and lack of heat recovery mechanisms. Future development of energy-efficient dryers should focus on improvements in areas such as high-efficiency heat sources, closed-loop airflow, lightweight frames, precise temperature control, and modular design.

[0004] Existing equipment suffers from significant heat loss during operation, and the escaped heat is extremely detrimental to the site environment. Therefore, this energy-saving dryer, equipped with a PTC ceramic heater and a heat circulation device, was invented. It quickly and efficiently dries materials while saving energy and reducing heat loss. Thus, we propose an energy-saving dryer to address the aforementioned problems. Summary of the Invention

[0005] The main purpose of this invention is to provide an energy-saving dryer that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An energy-saving dryer includes a control component, a drying component installed in the inner cavity of the control component, a blowing component installed in the inner cavity of the control component, an air outlet duct I installed at the front and rear of the blowing component, and an air inlet duct II installed at the front and rear of the blowing component.

[0008] Preferably, the control component includes a housing, a control panel is mounted on the left side of the housing, an air outlet is mounted on the lower end of the housing, and the housing has a cavity inside.

[0009] Preferably, the drying assembly includes a partition plate installed inside the cavity of the outer shell, and a plurality of PTC ceramic heaters are installed at the upper left end of the outer shell.

[0010] Preferably, the blowing assembly includes a fixing block installed inside the first cavity of the outer shell, and a collection shell installed at the lower end of the fixing block. The collection shell has a second cavity, and multiple fans are installed inside the second cavity.

[0011] Preferably, the air outlet duct includes two connecting pipes, which are respectively installed at the front and rear ends of the housing, and each of the two connecting pipes has several air blowing pipes installed on its outer surface.

[0012] Preferably, the second air inlet duct includes a second connecting pipe, and the two second connecting pipes are respectively installed at the front end and the rear end of the collection shell, and the lower ends of the two second connecting pipes are jointly installed with a recovery shell.

[0013] Preferably, the blower pipes are parallel to each other and the PTC ceramic heaters are parallel to each other, and the ends of the two connecting pipes that are far apart from each other are respectively installed on the front and rear side walls of the inner cavity of the outer shell.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device achieves uniform and safe drying through its designed drying components, blowing components, and air outlet duct. The PTC ceramic heater is characterized by its self-limiting temperature; when the temperature reaches its Curie point, the resistance increases sharply, and the power automatically decreases, thus stabilizing within the set temperature range. This avoids the problems of continuous heating and overheating burnout that occur with traditional heating wires. Combined with the airflow from multiple fans, heat can be further evenly distributed to the surface of the printed material, preventing material deformation, ink carbonization, or fiber damage caused by localized overheating. It is especially suitable for temperature-sensitive digital printing scenarios. At the same time, the thermal response speed of the PTC ceramic heater is far superior to that of traditional heating wires or infrared heaters. It can reach the set operating temperature within seconds after being powered on, without the need for preheating. With the instant airflow from multiple fans, heat can be quickly transferred to the surface of the freshly printed substrate, directly shortening the drying cycle for single-sheet or single-roll printing.

[0016] This device achieves hot air recovery through its designed air inlet duct. In traditional drying equipment, the hot air heated by the printed materials is directly exhausted outside the equipment, resulting in significant heat loss. Hot air recovery, through its duct design, reintroduces this waste hot air into the air inlet of the PTC ceramic heater, preheating the newly drawn-in cold air. Simultaneously, the preheated air temperature is significantly increased, eliminating the need for the PTC ceramic heater to heat the air from zero; it only needs to replenish the heat difference between the preheated air and the target drying temperature, drastically reducing the PTC's power consumption. Depending on the printing substrate and drying temperature, hot air recovery can reduce overall energy consumption, making it particularly suitable for industrial digital printing machines, wide-format advertising inkjet printers, and other equipment that operates under high loads for extended periods, significantly reducing electricity costs in the long run.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figure 1 As shown, an energy-saving dryer includes a control component 1, a drying component 2 installed inside the control component 1, a blowing component 3 installed inside the control component 1, an air outlet duct 4 installed at the front and rear of the blowing component 3, and an air inlet duct 5 installed at the front and rear of the blowing component 3.

[0025] When implementing this solution, the operator first installs the device at the location where it is needed. Then, the operator places the digitally printed items that need to be dried under the control component 1. After that, the operator starts the drying component 2 and the blowing component 3 through the control component 1. The drying component 2 will then heat up quickly to generate hot air, and the blowing component 3 will blow this hot air from the control component 1 onto the surface of the digitally printed items, thereby achieving the drying effect.

[0026] Meanwhile, during the drying process, hot air will disperse in all directions. This hot air will not only raise the temperature of the drying area, but also cause the loss of this hot air. Especially in summer, the increased temperature will make the operator feel uncomfortable. By recycling this hot air through the air inlet duct 25, the room temperature can be reduced, and the power consumption of the drying component 2 can also be reduced.

[0027] Specifically, in order to dry, such as Figure 1 and Figure 2 As shown, in this solution, the control component 1 includes a housing 11, a control panel 12 is installed on the left side of the housing 11, an air outlet plate 13 is installed at the lower end of the housing 11, and the housing 11 has a cavity inside.

[0028] For further details, please refer to [link / reference]. Figure 3 The drying assembly 2 includes a partition plate 21, which is installed inside the cavity of the outer shell 11. Several PTC ceramic heaters 22 are installed on the upper left end of the outer shell 11.

[0029] For further details, please refer to [link / reference]. Figure 5 The blowing component 3 includes a fixing block 31, which is installed inside the cavity 1 of the outer shell 11. A collection shell 32 is installed at the lower end of the fixing block 31. The collection shell 32 has a cavity 2, and multiple fans 33 are installed inside the cavity 2.

[0030] For further details, please refer to [link / reference]. Figure 4 The air outlet duct 4 includes two connecting pipes 41, which are respectively installed at the front and rear ends of the housing 32. Several air blowing pipes 42 are installed on the outer surface of the two connecting pipes 41.

[0031] Further, see Figure 4 Several air blowing pipes 42 are parallel to several PTC ceramic heaters 22, and the ends of two connecting pipes 41 that are far apart from each other are respectively installed on the front and rear side walls of the inner cavity of the outer shell 11.

[0032] When implementing this solution, the operator first installs the device at the location where it is needed. Then, the operator places the digitally printed items to be dried under the air outlet plate 13. After that, the operator starts the PTC ceramic heater 22 and the multi-fan 33 through the control panel 12. The PTC ceramic heater 22 will then heat up quickly to generate hot air, and the multi-fan 33 will blow this hot air from inside the air outlet plate 13 onto the surface of the digitally printed items, thereby achieving the drying effect.

[0033] The core principle of the control panel 12 controlling the PTC ceramic heater 22 and the multi-fan 33 can be summarized as follows: the control panel receives the user's instructions, converts them into electrical signals, and then controls the power input of the motor through different circuit methods, such as changing the voltage, current or signal frequency, thereby realizing the start, stop and speed adjustment of the control panel 12 and the multi-fan 33.

[0034] The air outlet plate 13 requires an external cable to connect the PTC ceramic heater 22 and the multi-fan 33 to provide power to them.

[0035] Example 2, which is based on Example 1, can recover hot air.

[0036] Specifically, in order to recover hot air, such as Figure 3 As shown, in this scheme, the air inlet duct 2 5 includes connecting pipe 2 51. The two connecting pipes 2 51 are respectively installed at the front end and the rear end of the collection shell 32, and the lower ends of the two connecting pipes 2 51 are jointly installed with the recovery shell 52.

[0037] When this solution is implemented, during the drying process, the hot air will disperse in all directions. This hot air will not only raise the temperature of the drying area, but will also be lost. Especially in summer, the increased temperature will cause discomfort to the operators. Through the design of the connecting pipe 51 and the recovery shell 52, the multiple fans 33 can draw in air and then allow the blown hot air to return to the connecting pipe 51 through the recovery shell 52, and then to the collection shell 32 to achieve airflow. This recovers the hot air, which not only reduces the room temperature, but also reduces the power consumption of the drying component 2.

[0038] In summary, the implementation process of this utility model is as follows:

[0039] The operator first installs the device at the location where it is needed. Then, the operator places the digitally printed items to be dried under the air outlet plate 13. After that, the operator starts the PTC ceramic heater 22 and the multi-fan 33 through the control panel 12. The PTC ceramic heater 22 will heat up quickly to generate hot air, and the multi-fan 33 will blow this hot air out from the air outlet plate 13 to the surface of the digitally printed items, thereby achieving the drying effect.

[0040] Meanwhile, during drying, hot air disperses everywhere. This not only raises the temperature of the drying area but also causes the loss of hot air. Especially in summer, the increased temperature can cause discomfort to the operator. Through the design of connecting pipe 2 51 and recovery shell 52, the multiple fans 33 allow the hot air blown out to re-enter the connecting pipe 2 51 through the recovery shell 52 and then into the collection shell 32 to achieve airflow. This recovers the hot air, which not only reduces the room temperature but also reduces the power consumption of the drying component 2.

[0041] It should be noted that the specific installation method, circuit connection method, and control method of the PTC ceramic heater 22 and the multi-fan 33 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
