Description

Technical Field

[0001] The utility model relates to the technical field of digital direct-injection machines, in particular to a drying device for a digital direct-injection machine. Background Art

[0002] Digital inkjet printers have great investment advantages, such as low investment, low printing cost, optional printing size, high printing quality, small space occupation, few operators, low operating cost, and wide selection of printing material types and thickness. In addition, professional digital printing inks can achieve saturated and bright colors, wide color gamut, and good transition, far exceeding the traditional printing effect. After the base plate is printed and dried, it is generally taken out from the machine outlet manually. Because the surface temperature is high after drying, it is not easy to take it out, and there is a risk that the worker's palm will be caught in the conveyor belt when taking it out.

[0003] For example, Chinese patent announcement No. CN215551995U discloses a drying device for digital printing. When in use, the base plate to be printed is placed on the conveyor belt, and a turnover box is placed on one side of the unloading mechanism. The base plate is printed and dried by the digital printer and the dryer respectively. The conveyor belt continues to move with the base plate after drying. When the base plate moves to the edge of the conveyor belt, it slides along the guide plate into the arc groove on the top surface of the bearing block. At this time, the first electric cylinder is started, and the rack is pushed to move horizontally by the first electric cylinder, thereby driving the spur gear to rotate, and the connecting rod is driven to rotate by the rotation of the spur gear. , and then drive the bearing block to rotate, the bearing block deflects and separates from the press switch, the second electric cylinder starts to close the door body, blocking the bottom plate on the conveyor belt from continuing to flow out, when the bearing block deflects to a certain angle, the bottom plate in the arc groove slides into the turnover box, and the design of the arc groove surface makes the printing surface of the bottom plate always face upward. After unloading is completed, the first electric cylinder pulls its piston rod to reset, and then drives the rack to reset, so that the spur gear reverses, thereby driving the bearing block to reset through the connecting rod. The bearing block resets and presses the quick closure, and the second electric cylinder resets the door body to open, and so on and so forth, to achieve automatic unloading, which is highly practical.

[0004] However, the drying device for digital printing in the above application has a fixed height of the dryer, and during drying, local over-drying or local under-drying may occur, so there are certain limitations.

[0005] For this reason, we urgently need to provide a drying device for a digital direct-injection machine. Utility Model Content

[0006] The purpose of the utility model is to provide a drying device for a digital direct-injection machine, so as to solve the problem that the drying device for digital printing proposed in the above-mentioned background technology has a fixed height of the dryer, and during drying, local over-drying or local under-drying may occur.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drying device for a digital direct-injection machine, comprising a dryer body and a conveyor belt, wherein the conveyor belt is installed inside the dryer body, and a drying device and a cooling device are arranged on the right side of the dryer body.

[0008] The drying device comprises an adjusting unit, a drying unit and a buffer unit.

[0009] The adjusting unit includes a supporting frame, an electric lifting rod, and a mounting frame. The supporting frame is fixedly connected to the right side of the dryer body, the electric lifting rod is installed at the bottom center of the supporting frame, and the mounting frame is fixedly connected to the bottom of the electric lifting rod. When facing fabrics of different thicknesses, the electric lifting rod is started to drive the mounting frame to move downward, thereby driving the drying unit at the bottom of the mounting frame to move downward to contact the surface of the fabric, thereby drying the prints on the surface of the fabric, thereby improving the application scope of the device.

[0010] A further improvement is that the drying unit includes a rotating bearing, a rotating shaft, an electric heating rod, and a drying roller. The two rotating bearings are respectively fixedly connected to the front and rear inner walls of the mounting frame, the front and rear ends of the rotating shaft are respectively rotatably connected to the inside of the rotating bearing, the electric heating rod is installed inside the rotating shaft, and the drying roller is fixedly connected to the outside of the rotating shaft. The cloth transported by the conveyor belt contacts the surface of the drying roller, and the friction between the two drives the rotating shaft inside the drying roller to rotate inside the rotating bearing, and the electric heating rod inside the rotating shaft transfers heat to the drying roller, thereby realizing the drying roller rolling to dry the cloth surface.

[0011] A further improvement is that an installation compartment is opened inside the rotating shaft, the electric heating rod is installed inside the installation compartment, and the drying roller is made of alumina material. Alumina has good thermal conductivity, thereby improving the drying efficiency, reducing heat consumption, and saving energy.

[0012] A further improvement is that the buffer unit includes a spring cavity, a flexible spring, and a sliding rod. The spring cavity is opened inside the bottom of the electric lifting rod, and the flexible spring is installed inside the spring cavity. The sliding rod is fixedly connected to the bottom of the flexible spring and slidably connected to the inside of the spring cavity, and its bottom is fixedly connected to the mounting frame.

[0013] A further improvement is that electric contacts are fixedly installed at the center of the top wall of the spring cavity and the top center of the sliding rod. When the drying roller moves down to contact the surface of the cloth, the drying roller generates an upward thrust to push the sliding rod connected to the mounting frame to slide toward the inside of the spring cavity and squeeze the flexible spring until the two electric contacts come into contact, thereby sending an electrical signal to stop the electric lifting rod from moving downward, thereby avoiding excessive downward movement and affecting the normal transmission of the cloth.

[0014] A further improvement is that the cooling device includes a cooling box, a heat dissipation fan, an air supply pipe, an air distribution pipe, and a blow hood, the cooling box is installed at the right end of the dryer body, the heat dissipation fan is installed at the top center of the cooling box, the air supply pipe is fixedly connected to the bottom air outlet of the heat dissipation fan and extends into the interior of the cooling box, the air distribution pipe is fixedly connected to the bottom of the air supply pipe, and several blow hoods are equidistantly fixedly connected to the bottom of the air distribution pipe.

[0015] A further improvement is that inlet and outlet ports are provided on the outer surfaces of the left and right sides of the cooling box. The surface temperature of the cloth after drying is relatively high. Therefore, when it passes through the interior of the cooling box through the inlet and outlet ports, the heat dissipation fan is started to blow cold air into the interior of the air supply pipe, and then flows to the interior of the air distribution pipe, and finally blown out through the blow hood, thereby quickly dissipating the heat of the cloth and preventing workers from being burned when collecting the cloth.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. When facing fabrics of different thicknesses, the drying device of the digital direct-injection machine starts the electric lifting rod to drive the mounting frame to move downward, thereby driving the drying unit at the bottom of the mounting frame to move downward to contact the surface of the fabric, thereby drying the print on the surface, thereby improving the application range of the device.

[0018] 2. In the drying device of the digital direct-injection machine, when the drying roller moves down to contact the surface of the fabric, the drying roller generates an upward thrust to push the sliding rod connected to the mounting frame to slide toward the inside of the spring cavity and squeeze the flexible spring until the two electrical contacts come into contact, thereby sending an electrical signal to stop the electric lifting rod from moving down excessively to avoid affecting the normal transmission of the fabric.

[0019] 3. The drying device of the digital direct-injection machine has a high surface temperature of the fabric after drying. Therefore, when it passes through the inlet and outlet and passes through the interior of the cooling box, the heat dissipation fan is started to blow cold air into the interior of the air supply pipe, and then flows to the interior of the air distribution pipe, and finally blown out through the blow hood, thereby quickly dissipating the heat of the fabric and preventing workers from being burned when collecting the fabric.
