Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printing ink drying mechanism. Background Technology

[0002] In the printing industry, ink drying is a crucial step in the printing process. Its efficiency and quality directly affect the drying effect, color stability, and yield of printed materials. As the printing industry develops towards high speed, precision, and intelligence, the market has placed higher demands on the efficiency, stability, and adaptability of ink drying equipment.

[0003] Chinese Patent Publication No. CN222610727U discloses a printing ink drying mechanism, which provides a printing ink drying mechanism with a dispersing and guiding structure. The printing ink drying mechanism includes a wind box, a guiding component, and a diversion structure. The wind box is provided with a guiding component for guiding hot air. A diversion structure for uniformly dispersing hot air is provided between the wind box and the inner wall of the drying chamber. By controlling the cylinder to drive the rack to move back and forth, the guide plate on the rack will swing back and forth from left to right under the transmission action of the rack and gear. This can uniformly disperse and guide the heated air so that the hot air can flow down from the top center of the drying chamber and flow into the center of the drying chamber from the air guide ports on the left and right sides. In this way, the hot air is evenly blown onto the tray containing the printed matter from different directions so that the printed matter can be heated evenly.

[0004] The aforementioned patent documents still have the following defects in practice:

[0005] The lack of an active fixing structure for printed materials means that relying solely on tray support is insufficient to withstand the impact of high-speed drying airflow, which can easily lead to the offset or flipping of printed materials, resulting in uneven ink drying or even misalignment of patterns. Utility Model Content

[0006] The main purpose of this invention is to provide a printing ink drying mechanism that can effectively solve the problem of printed materials shifting or flipping.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A printing ink drying mechanism includes a door, a box body rotatably connected to the front right side of the door, a heater fixedly connected to the upper end of the box body, a second air duct fixedly connected to the upper end of the heater, an air pump fixedly connected to the end of the second air duct away from the heater, a fixing device fixedly connected to the rear end of the air pump, a conveying mechanism fixedly connected to the inner wall of the box body, and several ventilation openings opened at the front end of the box body.

[0009] Preferably, the conveying mechanism includes an air supply channel, the left and right ends of which are fixedly connected to the left and right walls of the inner cavity of the box, and several strip-shaped air ducts are fixedly connected to the upper end of the inclined air duct on the same layer as the air supply channel.

[0010] Preferably, the air supply channel has four layers of double-inclined air ducts, each layer of double-inclined air ducts is upward and inclined to each other, the upper end of the strip air duct is provided with a strip air outlet, and the air outlet of the heater is connected to the inner cavity of the air supply channel and the inner cavity of the strip air duct.

[0011] Preferably, the fixing device includes four cavity plates. The left and right ends of the cavity plates are fixedly connected to the inner side of the air supply channel. A fixing plate is fixedly connected to the upper end of the cavity plates. A plurality of air holes are opened on the upper end of the fixing plate. A plurality of arc-shaped rubber blocks are fixedly connected to the upper end of the fixing plate. A duct is fixedly connected to the left and right ends of the front end of the cavity plates. A control mechanism is fixedly connected to the lower end of the plurality of ducts. The front part of the control mechanism is fixedly connected to the rear end of the air pump.

[0012] Preferably, each cavity plate is located below the inclined air duct of the same layer air supply channel, and the cavity plate has a partition that divides the cavity plate into left and right parts.

[0013] Preferably, the control mechanism includes a diverter tube, the front end of which is fixedly connected to the rear end of the air pump, a connecting rod rotatably connected to the vertical part of the diverter tube, two semi-circular blocks fixedly connected to the outer surface of the connecting rod, and a handle fixedly connected to the front end of the connecting rod.

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

[0015] 1. In this embodiment, a four-layer double-inclined air duct structure is set up. Each layer of air duct is upward and inclined to each other. Combined with the strip air outlet of the strip air duct, hot air is spread all over the fixed plate from different angles. The inclined air duct blows some of the hot air obliquely upward to form a three-dimensional airflow field. The strip air duct (including the L-shaped end air duct) makes the hot air fall evenly from the top and form a circulating airflow through the gap of the air duct. This avoids the local wind force being too strong and blowing away the ink. At the same time, it ensures that the surface of the printed matter is heated evenly. A heating plate is set at the lower end of the cavity plate. In conjunction with the heater, it continuously supplies heat to maintain a stable temperature inside the chamber and further improves the drying efficiency.

[0016] 2. In this embodiment, the number of cavity plate layers involved in adsorption can be flexibly adjusted according to the size and quantity of the printed materials. It does not require full-load operation, and some airflow channels can be closed when not necessary, thereby reducing the load on the air pump, reducing energy consumption, and extending the service life of the equipment.

[0024] 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.

[0025] Example 1, as Figures 1-2 As shown, a printing ink drying mechanism includes a door 1, a box body 2 rotatably connected to the front right side of the door 1, a heater 3 fixedly connected to the upper end of the box body 2, an air duct 7 fixedly connected to the upper end of the heater 3, an air pump 6 fixedly connected to the end of the air duct 7 away from the heater 3, a fixing device 5 fixedly connected to the rear end of the air pump 6, a conveying mechanism 4 fixedly connected to the inner wall of the box body 2, and several ventilation openings 8 opened at the front end of the box body 2.

[0026] In this embodiment, the printed cardboard is placed on the fixing device 5, the heater 3 and the air pump 6 are started. The air pump 6 draws in the air from the box 2 through the fixing device 5, and then delivers it to the heater 3 through the air duct 2 7. The heater 3 heats the air and then delivers it to the box 2 through the conveying mechanism 4 to dry the printing ink. The air enters and exits the box 2 through the ventilation port 8.

[0027] To prevent the ink from being blown away during ink drying, please refer to... Figure 3The conveying mechanism 4 includes an air supply channel 41. The left and right ends of the air supply channel 41 are fixedly connected to the left and right walls of the inner cavity of the box 2, respectively. Several strip air channels 42 are fixedly connected to the upper end of the inclined air channel on the same layer of the air supply channel 41. The air supply channel 41 has four layers of double inclined air channels. Each layer of double inclined air channels is upward and inclined to each other. A strip air outlet is opened at the upper end of the strip air channel 42. The air outlet of the heater 3 is connected to the inner cavity of the air supply channel 41 and the inner cavity of the strip air channel 42.

[0028] During implementation, hot air is blown upwards at an angle from the air supply channel 41, and another part of the air is sent out from the top of the strip air duct 42. The frontmost and rearmost strip air ducts 42 are L-shaped, so that after the air is blown out from the top, it flows downwards from the gaps between the strip air ducts 42, so that the hot air covers the top of the fixing plate 51 and dries the printing ink on the cardboard. This reduces the impact of the air on the ink and also improves the drying efficiency.

[0029] Example 2: To secure the cardboard, refer to... Figure 4 The fixing device 5 includes four hollow plates 55. The left and right ends of the hollow plates 55 are fixedly connected to the inner side of the air supply channel 41. A fixing plate 51 is fixedly connected to the upper end of the hollow plates 55. Several air holes 53 are opened on the upper end of the fixing plate 51. Several arc-shaped rubber blocks 52 are fixedly connected to the upper end of the fixing plate 51. Air ducts 54 are fixedly connected to the left and right parts of the front end of the hollow plates 55 respectively. A control mechanism 56 is fixedly connected to the lower end of several air ducts 54. The front part of the control mechanism 56 is fixedly connected to the rear end of the air pump 6.

[0030] Each cavity plate 55 is located below the inclined air duct of the same layer air supply channel 41. The cavity plate 55 has a partition inside, which divides the cavity plate 55 into left and right parts.

[0031] During the process, the cardboard is placed on the arc-shaped rubber block 52. The arc-shaped rubber block 52 lifts the cardboard and increases the friction. Then, the air pump 6 draws air in through the air hole 53 through the control mechanism 56, the air duct 54 and the cavity plate 55, which changes the pressure on the cardboard and makes the cardboard be sucked above the fixing plate 51 to fix the cardboard. The cavity plate 55 has a heating plate at the lower end to ensure the constant temperature inside the box 2 and improve the drying efficiency.

[0032] For further details, please refer to [link / reference]. Figure 5 The control mechanism 56 includes a diversion pipe 561, the front end of which is fixedly connected to the rear end of the air pump 6, a connecting rod 563 rotatably connected to the vertical part of the diversion pipe 561, two semi-circular blocks 562 fixedly connected to the outer surface of the connecting rod 563, and a handle 564 fixedly connected to the front end of the connecting rod 563.

[0033] During implementation, the outer surface of the connecting rod 563 is coated with a damping coating. When the operator grasps the handle 564, the handle 564 drives the connecting rod 563 to rotate, and the connecting rod 563 drives the semi-circular block 562 to rotate. The control mechanism 56 can be adjusted according to different cardboard sizes and quantities. When not needed, the control mechanism 56 can be turned off to reduce the load and extend the machine's service life.

[0034] It should be noted that the specific installation method, circuit connection method, and control method of the heater 3 and air pump 6 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
