Description

Technical Field

[0001] This utility model belongs to the technical field of paper box drying equipment, specifically relating to a color packaging paper box printing drying equipment. Background Technology

[0002] After color printing, cardboard boxes need to be dried to allow the ink on their surface to adhere quickly.

[0003] For example, a color packaging paper box printing drying device, as disclosed in announcement number CN218315828U, includes a drying chamber. One outer wall of the drying chamber has a notch connecting to the outside, and a door for storing and retrieving paper boxes is hinged to the notch. The device also includes a rotating mechanism for rotating the paper boxes at a uniform speed. The rotating mechanism includes a drive motor and a turntable. The turntable, which carries the rotating paper boxes, is rotatably mounted at the bottom of the drying chamber. The drive motor is fixedly mounted at the bottom of the drying chamber, and its output shaft is fixedly connected to a rotating shaft via a coupling. The upper end of the rotating shaft passes through the bottom of the drying chamber and is fixedly connected to the center of the bottom of the turntable. The device also includes a drying mechanism for drying the paper boxes. By using the rotating mechanism, the paper boxes to be dried can be rotated at a uniform speed, ensuring that the ink on their surface is heated evenly. This not only guarantees good quality of the dried paper boxes but also reduces energy consumption.

[0004] The inventors believe that in the above-mentioned prior art, drying a rotating cardboard box by using an infrared heating plate can achieve uniform heating of the cardboard box to a certain extent, but its energy consumption reduction effect is not ideal, because some of the far-infrared rays generated by the infrared heating plate are absorbed by the inner wall of the drying chamber and cannot be efficiently reflected to the surface of the cardboard box for heating and drying.

[0005] In view of this, the present invention provides a color packaging paper box printing and drying device to solve the above problems. Utility Model Content

[0006] (1) Technical problems to be solved

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a color packaging paper box printing drying device, which aims to solve the technical problem of improving the diffuse reflection of far-infrared rays in the drying oven under the existing technology.

[0008] (2) Technical solution

[0009] To solve the above-mentioned technical problems, this utility model provides a color packaging paper box printing drying device, which includes a drying box and infrared heating plates symmetrically installed on the side wall of the drying box. The opening end of the drying box is hinged with a door, and a motor is installed at the bottom of the drying box. The output end of the motor passes through the bottom of the drying box and is connected to a rotating frame for supporting the paper boxes. An embossed aluminum plate is coupled on the inner wall of the drying box to improve the diffuse reflection inside the drying box.

[0010] When using the color packaging paper box printing drying device of this technical solution, the paper box is placed on the rotating frame, the door is closed, and the infrared heating plate and motor are started. The far-infrared energy generated by the infrared heating plate will irradiate the paper box. The rotation of the rotating frame driven by the motor will make the paper box rotate continuously, thereby achieving uniform heating and drying of the paper box. When the far-infrared energy emitted by the infrared heating plate irradiates the inner wall of the drying chamber, the embossed aluminum plate not only improves the reflection effect of the far-infrared energy, but also improves the diffuse reflection of the far-infrared energy in the drying chamber through the various uneven patterns on the surface of the embossed aluminum plate, so that it irradiates the paper box from different directions, achieving efficient and uniform drying of the paper box. Since the far-infrared energy weakens due to attenuation, it not only reduces the energy consumption of drying paper boxes, but also speeds up the drying speed of paper boxes.

[0011] Preferably, the color packaging paper box printing and drying device further includes a support mechanism for placing the paper boxes. The support mechanism includes: brackets and support screens. The brackets are symmetrically arranged on the top edge of the rotating frame, and the support screens are horizontally connected between the brackets. There are three sets of support screens, with each set of support screens arranged at intervals and in a hollowed-out shape. Through the arrangement of the support mechanism, paper boxes can be placed on each layer of support screens to achieve batch drying of paper boxes. At the same time, the hollowed-out shape of the support screens will not hinder the flow of heat.

[0012] Furthermore, the color packaging paper box printing drying device also includes a moisture-absorbing mechanism to extract moisture from inside the drying chamber. The moisture-absorbing mechanism includes: a fan installed on the top of the drying chamber, with the fan's exhaust end extending into the interior of the drying chamber; a through-vent on the surface of the chamber door; a dust filter inside the vent; and three sets of vents arranged at intervals. By controlling the operation of the fan, the moisture generated by drying the paper boxes inside the drying chamber can be quickly discharged to the outside, thereby shortening the drying time of the paper boxes and further improving drying efficiency. At the same time, the dust filter can effectively prevent dust from the external environment from entering the drying chamber, effectively reducing dust adsorption on the surface of the paper boxes and improving the production quality of the paper boxes.

[0013] Furthermore, the bottom of the drying oven is symmetrically equipped with support legs at the four corners to support the entire drying oven, and the bottom of the support legs is integrated with a foot brace.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention improves diffuse reflection within the drying chamber by coupling a layer of embossed aluminum plate to the inner wall of the drying chamber. When the infrared heating plate emits far-infrared energy, it can better act on the surface of the cardboard box, thus achieving fast, efficient, and energy-saving drying of the cardboard box.

[0023] This specific embodiment is a color packaging paper box printing drying device, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the color packaging paper box printing drying device includes: a drying box 1 and infrared heating plates 7 symmetrically installed on the side wall of the drying box 1. The opening end of the drying box 1 is hinged with a door 2. A motor 3 is installed at the bottom of the drying box 1. The output end of the motor 3 passes through the bottom of the drying box 1 and is connected to a rotating frame 4 for carrying the paper box. An embossed aluminum plate 8 is coupled on the inner wall of the drying box 1 to improve the diffuse reflection inside the drying box 1.

[0024] It also includes a support mechanism for placing cardboard boxes. The support mechanism includes a bracket 5 and a support mesh plate 6. The bracket 5 is symmetrically arranged on the top edge of the rotating frame 4. The support mesh plate 6 is horizontally connected between the brackets 5. It also includes a moisture-absorbing mechanism for extracting moisture from the inside of the drying box 1. The moisture-absorbing mechanism includes a fan 10 installed on the top of the drying box 1. The exhaust end of the fan 10 extends into the inside of the drying box 1. The surface of the box door 2 is provided with a through-ventilation port 11. The inside of the ventilation port 11 is provided with a dust filter. The infrared heating plate 7, the motor 3 and the fan 10 are all electrically connected to an external power source through a control switch.

[0025] Among them, the support mesh plate 6 is provided in three sets, and the support mesh plate 6 in each set is arranged at intervals and is arranged in a hollow shape; the ventilation port 11 is provided in three sets, and the ventilation port 11 in each set is arranged at intervals.

[0026] In addition, the bottom of the drying box 1 is symmetrically provided with four support legs 9 at the four corners to support the entire drying box 1. The bottom of the support legs 9 is integrally connected with a foot brace to support the entire device.

[0027] Working principle: When using the device of this technical solution, by opening the box door 2, the cardboard boxes are placed sequentially on each of the support mesh plates 6 and the rotating frame 4. Then, the box door 2 is closed, and the infrared heating plate 7 and the motor 3 are started. The motor 3 drives the rotating frame 4 to rotate, so that the cardboard boxes rotate inside the drying chamber 1. The far-infrared rays generated by the infrared heating plate 7 can irradiate the cardboard boxes, and the embossed aluminum plate 8 coupled to the inner wall of the drying chamber 1 can improve the diffuse reflection ability, so that the far-infrared rays can act on the surface of the cardboard boxes comprehensively and efficiently, achieving efficient and uniform drying of the cardboard boxes. Since the attenuation of far-infrared rays weakens, it not only reduces the energy consumption of drying cardboard boxes, but also speeds up the drying speed of the cardboard boxes.
