Description

Technical Field

[0001] The utility model relates to the technical field of gift box preparation, and more specifically, to a sectional heating and drying box for gift box preparation. Background Art

[0002] Gift box, also known as gift box, is a practical gift packaging with the main purpose of giving gifts to relatives and friends and expressing affection. It is an extension of the social need of a functional packaging method. According to the packaging materials, there are paper products, plastic products, metals, bamboo and wooden packaging, glass containers and composite materials, etc. Generally, gift boxes are mostly made of paper packaging. During the preparation process, the gift boxes need to be dried due to spraying paint or other aspects. Therefore, a drying oven is needed when preparing the gift boxes.

[0003] After searching, a Chinese patent with publication number CN218034282U discloses a packaging box processing and drying device, wherein a reflux component is installed under a drying box, and the hot air inside the drying box is blown by a fan, passes through a transmission chain plate and contacts with the reflux component. Under the action of the reflux component, the hot air forms a vortex, which can dry the packaging box attached to the surface of the transmission chain plate. At the same time, a cylinder body, a first bracket and a second bracket are provided inside the reflux component, and the cylinder body is connected to the second bracket. In this way, the distance between the first bracket and the second bracket can be changed under the action of the cylinder body, thereby changing the reflux efficiency of the hot air.

[0029] Working principle: This utility model designs a segmented heating and drying box for gift box preparation. The specific structure is as shown in the attached manual. Figure 1-4As shown, when the present technical solution is used, the gift box placed or transmitted to the transmission belt 9 is first positioned, and the piston rod of the cylinder 113 is extended to push the clamping plate 111 to push the gift box, and the gift box is kept in the middle position of the transmission belt 9, so that the gift box will not fall due to placement offset during the transmission to the first synchronous conveyor belt 6 and enter the interior of the oven 2, thereby improving the stability during transmission; secondly, in the present solution, the oven 2 is divided into three parts: a first heating section, a second heating section and an air-drying section, wherein the first heating section is the area where the first synchronous conveyor belt 6 is located, the second heating section is the area where the second synchronous conveyor belt 14 is located, and the air-drying section is the area where the third synchronous conveyor belt 17 is located, and the second synchronous conveyor belt 14 on the second heating section is staggered with the first synchronous conveyor belt 6 and the third synchronous conveyor belt 17, and the air-drying section and the heating section on the air guide shell at each position are separated by a partition 22, so that high temperature will not be generated inside the air guide shell of the air-drying section, Since the second synchronous conveyor belt 14 is staggered with the first synchronous conveyor belt 6 and the third synchronous conveyor belt 17, the gift box is first dried with hot air during the transmission of the first synchronous conveyor belt 6. During the transmission process, the contact surface between the bottom of the gift box and the first synchronous conveyor belt 6 remains unchanged, which makes the existing transmission heating and drying method not completely dry the bottom of the gift box. By transmitting the gift box from the first synchronous conveyor belt 6 to the displaced second synchronous conveyor belt 14, the original transmission contact position is changed, so that the part that has not been in direct contact with the hot air is exposed to the air, thereby achieving effective drying treatment of the bottom position. After the gift box is transmitted from the second synchronous conveyor belt 14 to the third synchronous conveyor belt 17, hot air is no longer blown directly. Due to the hot air input from the first heating section and the second heating section, the overall internal heat of the oven 2 is sufficient, and the drying effect can be maintained without directly introducing hot air in the air-drying section, and it can be used to reduce the temperature of the gift box when it is discharged, which is convenient for subsequent operations.
