Description

Technical Field

[0001] This utility model relates to the field of cold drying equipment, and in particular to a cold drying device for paper box printing. Background Technology

[0002] In the paper box printing industry, the drying process is a core technical step to ensure ink adhesion and printing accuracy. Traditional cold air drying technology, because the cold air blows in one direction, causes the ink to shift on the paper box surface, resulting in ink flow, especially when not fully dry. This flow can cause ink to accumulate in a specific direction, leading to blurred or distorted lettering edges. For example, the wind direction may cause ink to accumulate on the windward side, while the leeward side dries faster, causing lettering to tilt or stretch.

[0003] Conventional cold air drying fans require multiple motors to control simultaneously when adjusting the angle on both sides. Due to the large number of motors, the overall cost of the production line is also high. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and achieve the above-mentioned functions, this utility model provides a paper box printing cold drying device.

[0005] This utility model is achieved through the following technical solution:

[0006] A paper box printing cold drying equipment includes a cold drying base plate installed above the paper box conveyor belt, a fixed base plate installed at the rear end of the cold drying base plate, and cold drying side plates rotatably connected to both sides. The cold drying base plate and the cold drying side plates are provided with grids that run vertically through the paper box. Two vertical fans are symmetrically fixed on the cold drying base plate, and one oblique fan is fixed on each cold drying side plate.

[0007] A motor is mounted on the fixed base plate, and the output shaft of the motor is fixedly connected to the rotating shaft in the center of the front cold drying base plate through a coupling.

[0008] Two columns are installed on both sides of the cold drying base plate and on the inside of the cold drying side plate. Rotating cylinders b are rotatably installed on the front and rear columns on both sides of the cold drying base plate.

[0009] A support column is fixed on the upright of the cold drying side plate. A retaining ring is fixed in the center of each support column. The rear half of the support column on the left side is rotatably connected to a rotating cylinder a, and the front half of the support column on the right side is rotatably connected to a rotating cylinder a. Pull rope a and pull rope b are fixed on the left and right rotating cylinders a respectively. The other ends of pull rope a and pull rope b pass over and abut against the top of the rotating cylinder b and are fixed to the central rotating shaft.

[0010] A front cover plate and a rear cover plate are installed at the front and rear of the cold drying base plate, respectively. The top of the front cover plate and the rear cover plate are connected by a top plate. A refrigeration unit is installed on the top plate, and the refrigeration evaporator tube of the refrigeration unit is installed below the top plate.

[0011] Furthermore, it also includes two accordion covers fixed on both sides. The accordion covers are three-folded, with one side fixed to the front, rear, and side edges of the cold-drying side plate, and the other side fixed to the side edges of the front cover plate, rear cover plate, and top plate. The two accordion covers are stretched and rotated around the rotation axis of the cold-drying bottom plate and the cold-drying side plate.

[0012] Furthermore, both the cooling base plate and the cooling side plate are provided with fan slots, and both the vertical fan and the oblique fan are snapped into the fan slots.

[0013] Furthermore, a bearing seat is installed in the middle of the front end of the cold drying base plate, and the front end of the rotating shaft is rotatably connected to the bearing seat.

[0014] Furthermore, two columns are installed between the shaft and the right vertical fan, and a rotating cylinder c is rotatably installed between these columns. The pull rope b crosses over and abuts above the rotating cylinder c, and is then wound around and fixed to the shaft from below.

[0015] The pull rope a wraps around the rotating shaft from above after crossing the rotating cylinder b.

[0016] Furthermore, the pull ropes a and b are parallel to each other and are located in the front and rear halves of the rotating shaft, respectively. The stretching lengths of the pull ropes a and b ensure that the tilt angles of the inclined fans on both sides remain consistent.

[0017] Furthermore, both the vertical fan and the angled fan can blow the cool air inside the device downwards and outwards, and an air inlet is provided on the top plate.

[0018] Furthermore, the front and rear center lines of this device are aligned with the center of the carton conveyor belt.

[0019] The beneficial effects of this utility model are:

[0020] This invention can blow cold air obliquely from both sides to dry the ink after printing on the paper box. It is driven by only a single motor, which is low cost. The rotating shaft and the rope connection can ensure that the blowing angle on both sides is consistent, which is ingenious design. The sides are also fixed with accordion covers, which can be folded and unfolded in the direction of rotation to ensure structural stability. Attached Figure Description

[0039] like Figures 1 to 9 As shown, this utility model includes a cold drying base plate 1 installed above the carton conveyor belt. A fixed base plate 102 is installed at the rear end of the cold drying base plate 1, and cold drying side plates 101 are rotatably connected to both sides. Both the cold drying base plate 1 and the cold drying side plates 101 are provided with vertically penetrating grilles 105 as cold air outlets. Two vertical fans 5 are symmetrically fixed on the left and right sides of the cold drying base plate 1, mainly providing longitudinal vertical air in the middle. Each cold drying side plate 101 is fixed with an oblique fan 501 to provide side air at an appropriate angle.

[0040] The fixed base plate 102 is equipped with a motor 3, which is a driving element. The output shaft of the motor 3 is fixedly connected to the rotating shaft 301 in the center of the front cold drying base plate 1 through a coupling.

[0041] refer to Figure 4 Two front and rear columns 6 are installed on both sides of the cold drying base plate 1 and the inner side of the cold drying side plate 101. A rotating cylinder b604 is rotatably installed on the front and rear columns 6 on both sides of the cold drying base plate 1 to facilitate raising the height of the pull ropes on both sides so that they do not interfere with the vertical fan 5. A bearing column 601 is fixed on the column 6 of the cold drying side plate 101. A retaining ring 602 is fixed in the center of each bearing column 601 to prevent the axial movement of the rotating cylinder a603. The fixing method can be conventional methods such as welding, which will not be described in detail. The rear half of the bearing column 601 on the left side Rotary connection is provided with rotating cylinder a603. The front half of the bearing column 601 on the right side is rotatably connected to rotating cylinder a603, which can be driven to rotate freely. Pull rope a7 and pull rope b701 are fixed on the left and right rotating cylinders a603 respectively. The two can be made of nylon or stainless steel chain rope. The fixing method is conventional methods such as bolt locking or welding. The other end of pull rope a7 and pull rope b701 both cross over and abut against the top of rotating cylinder b604 and are fixed to the central rotating shaft 301. When rotating shaft 301 rotates, it drives pull rope a7 and pull rope b701.

[0042] A front cover plate 2 and a rear cover plate 202 are installed at the front and rear of the cold drying base plate 1, respectively. The tops of the front cover plate 2 and the rear cover plate 202 are connected by a top plate 103. A cooler 4 is installed above the top plate 103. The evaporator tube 402 of the cooler 4 is installed below the top plate 103. The cooler 4 is a conventional cooler, similar to the air conditioning refrigeration scheme. The relevant principles will not be described in detail. The cooling medium in the evaporator tube 402 will generate low temperature, which will drive down the air temperature inside the device.

[0043] refer to Figure 1 The present invention also includes two accordion covers 201 fixed on both sides. The accordion covers 201 are three-folded. One side is fixed to the front, rear and side edges of the cold drying side plate 101, and the other side is fixed to the side edges of the front cover plate 2, the rear cover plate 202 and the top plate 103. The two accordion covers 201 are stretched and rotated around the rotation axis of the cold drying bottom plate 1 and the cold drying side plate 101. Of course, those skilled in the art should also know that the inner rotating edge of the accordion cover 201 should be fixed with screws or other conventional means around this center.

[0044] Both the cold drying base plate 1 and the cold drying side plate 101 are provided with fan slots 502, and the vertical fan 5 and the oblique fan 501 are both engaged in the fan slots 502 to ensure positioning.

[0045] The front end of the cold drying base plate 1 is equipped with a bearing seat 302, and the front end of the rotating shaft 301 is rotatably connected to the bearing seat 302.

[0046] refer to Figure 4 Two columns 6 are installed between the rotating shaft 301 and the right vertical fan 5. A rotating cylinder c605 is rotatably mounted between these columns 6. The pull rope b701 crosses over and abuts above the rotating cylinder c605, and is then wound around and fixed to the rotating shaft 301 from below. The pull rope a7 crosses the rotating cylinder b604 and is wound around the rotating shaft 301 from above, ensuring that the inclined fans 501 on both sides can simultaneously extend and rise when the rotating shaft 301 rotates. The pull rope a7 and pull rope b701 are parallel to each other and are located in the front and rear halves of the rotating shaft 301 respectively to prevent them from crossing and tangling. The stretching length of the pull ropes a7 and b701 ensures that the tilt angle of the inclined fans 501 on both sides remains consistent.

[0047] Both the vertical fan 5 and the oblique fan 501 can blow the cold air in the device downwards and outwards, and the top plate 103 is provided with an air inlet 104.

[0048] The front and rear center lines of this device are aligned with the center of the carton conveyor belt.

[0049] Of course, many existing technologies, such as the need for the bracket to be fixed directly above the conveyor belt, and the connection of the external host computer (or PLC control module) and power supply module, have been omitted in this utility model.

[0050] The principle of this invention is as follows: The two oblique fans of this invention blow out cool air from inside the device, drying the ink on the cardboard box from both sides to prevent the ink from shifting in one direction. Of course, although it is a quiet wind with low wind force, it can still cause the ink to bulge in the middle. Therefore, the two vertical fans in the middle blow air longitudinally to exert vertical pressure and evenly flatten the ink. The two sides can be blown synchronously and at a custom angle according to the actual effect. The four fans quickly dry the ink.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
