[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 7 A cardboard printing and drying device provided in this embodiment includes a conveyor 1, a protrusion 2 is arranged on the conveyor belt of the conveyor 1, a frame 3 located above the conveyor belt is arranged on the conveyor 1, a vent hole 4 is opened at one end of the frame 3, a dustproof net 5 is arranged on the frame 3 at one side of the vent hole 4, and a heating component 6 is arranged on the frame 3 at the other side of the vent hole 4, and a chip removal mechanism 7 is arranged at the other end of the frame 3.

[0028] In the utility model, the cardboard to be dried is placed on the protrusion 2 of the conveyor 1. The conveyor 1 adopts the belt conveyor structure commonly used in the prior art. The conveyor 1 delivers the cardboard to be dried into the rack 3. When the external air enters the rack 3 through the vent 4, it is heated by the heating component 6 to form hot air. The hot air heats and dries the cardboard. The dustproof net 5 on the vent 4 plays a dustproof role to prevent dust and impurities from entering the rack 3. During the drying process, the chip removal mechanism 7 removes impurities such as paper scraps and dust, thereby preventing the paper scraps and dust from causing a decrease in the heat transfer efficiency of the drying device. The heat of the drying device can be directly transferred to the cardboard without increasing heat loss, thereby greatly improving the drying efficiency.

[0029] It should be noted that when the chip removal mechanism 7 is working, the air in the frame 3 is discharged to the outside, so that the external air can enter the frame 3 through the vent hole 4, and then the air can pass through the heating component 6 and be heated, and further the hot air can flow axially on the surface of the paperboard, accelerating the flow speed of the air on the surface of the paperboard, thereby improving the drying speed;

[0030] Meanwhile, the protrusion 2 includes a cylindrical section arranged on the conveyor belt, and a hemispherical contact section is arranged on the top of the cylindrical section. When the cardboard is dried, it is located on the top of the contact section. The design of the protrusion 2 can avoid the lower surface of the cardboard being completely attached to the conveyor belt, resulting in a reduction in the heating area. The contact section adopts a hemispherical design, and the contact section is made of rubber material. While ensuring the stability of the cardboard on the protrusion 2, it can greatly increase the drying area of ​​the cardboard, thereby improving the drying speed.

[0031] Specifically, Figure 2-Figure 4 As shown, the chip removal mechanism 7 includes a mounting base 71 that passes through the frame 3, a draft fan 72 is provided on the side of the mounting base 71 away from the frame 3, an absorption cover 73 is provided on the end of the mounting base 71 facing the inside of the frame 3, and a filter assembly 74 is provided in the middle of the mounting base 71.

[0032] When the chip removal work is performed, the induced draft fan 72 on the mounting seat 71 discharges air to the outside, thereby generating negative pressure suction in the mounting seat 71. At this time, impurities such as paper scraps and dust on the cardboard in the frame 3 are sucked into the mounting seat 71 under the action of the negative pressure suction, and then the impurities such as paper scraps and dust are filtered out by the filter assembly 74, thereby achieving the removal of impurities such as paper scraps and dust on the cardboard;

[0033] An absorption cover 73 with a trapezoidal structure is provided at the opening position of the mounting seat 71, and the flared end of the absorption cover 73 faces the interior of the frame 3. The absorbed paper scraps and dust will pass through the absorption cover 73. The absorption cover 73 can prevent air backflow from causing paper scraps and dust to re-enter the frame 3, thereby ensuring the effective chip removal work of the chip removal mechanism 7.

[0034] Specifically, Figure 4 and Figure 5 As shown, the filter assembly 74 includes a fixing plate 741 fixed on the inner wall of the mounting seat 71 , a filter screen 743 is provided on the fixing plate 741 via a connecting rod 742 , and a first spring 744 is sleeved on the connecting rod 742 between the fixing plate 741 and the filter screen 743 .

[0035] Among them, the fixing plate 741 is fixed on the inner wall of the mounting seat 71, and the filter 743 is installed in the mounting seat 71 through the connecting rod 742. The filter 743 is used to filter out impurities such as paper scraps and dust. The first spring 744 on the connecting rod 742 can enable the filter 743 to vibrate slightly with the airflow, so that the impurities such as paper scraps and dust filtered out of the filter 743 are vibrated down, avoiding clogging of the filter 743 and ensuring the filtering effect of the filter 743.

[0036] It should be noted that a threaded end 745 is provided at one end of the connecting rod 742 away from the fixing plate 741, and a locking nut 746 is provided on the threaded end 745 to abut against the filter screen 743. When the filter screen 743 needs to be disassembled and replaced, the locking nut 746 on the threaded end 745 is opened, and then the filter screen 743 can be pulled out from the connecting rod 742, so that the filter screen 743 can be easily disassembled and assembled.

[0037] Specifically, Figure 4-Figure 6 As shown, an elastic component 75 is provided on the mounting seat 71, and the elastic component 75 includes a striking rod 751 that passes through the mounting seat 71, a limiting plate 752 is provided on the striking rod 751 at a position located inside the mounting seat 71, and a second spring 753 is sleeved on the striking rod 751 at a position between the limiting plate 752 and the inner wall of the mounting seat 71, a pull ring 754 is provided at one end of the striking rod 751 located outside the mounting seat 71, and a head 755 is provided at one end of the striking rod 751 close to the filter screen 743.

[0038] Among them, the impact rod 751 is pulled backward through the pull ring 754. At this time, the limit plate 752 squeezes the second spring 753 and compresses it, and then the pull ring 754 is released. Under the action of the restoring elastic force of the second spring 753, the impact rod 751 hits the filter 743, thereby causing the filter 743 to vibrate locally, so that impurities such as paper scraps and dust filtered out of the filter 743 fall down, and avoid adhering to the filter 743 and causing the filter 743 to be blocked. The top 755 on the impact rod 751 is made of rubber material, which can prevent the filter 743 from being damaged when the impact rod 751 hits the filter 743.

[0039] Specifically, Figure 2 , Figure 3 and Figure 7As shown, the heating assembly 6 includes a mounting frame 61 fixed inside the frame 3 , a wiring seat 62 is provided on the mounting frame 61 , and a plurality of electric heating tubes 63 are provided inside the mounting frame 61 .

[0040] Among them, the terminal socket 62 on the installation frame 61 is connected to the power supply, so that the electric heating tube 63 on the installation frame 61 is energized. The electric heating tube 63 performs heating work when working, on the one hand, it dries the cardboard, and on the other hand, it heats the air entering through the vent 4 to form hot air, which further heats and dries the cardboard.
