[0001] This utility model belongs to the field of pulp molding technology, and in particular relates to a rapid drying device for pulp molding. Background Technology
[0002] Pulp molding is an environmentally friendly product made from plant fibers through processes such as molding and drying. It is widely used in packaging, tableware, and industrial cushioning. Its core characteristics are biodegradability, renewability, and wide availability of raw materials. It is an important environmentally friendly material to replace plastic packaging. Its production process mainly includes five core links: raw material processing, pulping, molding, drying, and post-processing. After molding, it is still a wet preform and belongs to semi-finished products, which need to be dried.
[0003] After the pulp molding process, the wet preforms need to be placed on a tray, and then the tray is placed on the conveyor belt of the pulp molding dryer. The wet preforms on the tray are then sent into the drying chamber of the dryer for drying. When placing the trays containing the wet pulp molding preforms on the conveyor belt of the dryer, it usually requires multiple people to manually arrange the trays. Due to differences in skill level, the arrangement of the trays is not uniform and neat, which can easily lead to uneven heating in the dryer. Therefore, a rapid drying device for pulp molding is needed, which can push the trays containing the pulp moldings onto the dryer through a feeding structure, thereby avoiding manual intervention in tray arrangement. Utility Model Content

[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model places a tray containing wet molded pulp blanks on three horizontal support plates on the front. The output shaft of a servo motor drives the support plates on the surface of the scraper conveyor to move. After the servo motor drives the support plates to move a certain distance, it automatically stops. At this time, the cylinder is activated, and the output end of the cylinder drives the push plate to move to the right. The push plate pushes the tray onto the conveying system of the pulp molding dryer, and then the tray enters the drying chamber of the pulp molding dryer to dry the wet molded pulp blanks in the tray. This achieves the purpose of pushing the tray containing molded pulp onto the dryer through the feeding structure, thereby avoiding manual intervention in tray placement.
[0012] 2. This utility model uses the combination of the limiting slide rod and the limiting sleeve. When the output end of the cylinder drives the push plate to move to the right, the push plate is limited by the limiting sleeve and drives the limiting slide rod to move to the right, thereby improving the stability of the push plate and preventing the push plate from bending and deforming.

A servo motor 7 is fixedly mounted on the surface of tray 4. A fixed platform 8 is set on the left side of tray 6. Two symmetrical limiting slide rods 12 are fixedly connected to the top of the fixed platform 8. Through the cooperation of the limiting slide rods 12 and the limiting sleeve 13, when the output end of the cylinder 9 drives the push plate 10 to move to the right, the push plate 10 drives the limiting slide rods 12 to move to the right through the limiting sleeve 13, thereby improving the stability of the push plate 10 and preventing the push plate 10 from bending and deforming. The limiting slide rods 12 pass through the limiting sleeve 13 and are slidably connected to the limiting sleeve 13. A cylinder 9 is fixedly mounted on the top of the fixed platform 8.

[0022] Working Principle: In use, the user places the wet pulp molded preform in tray 6, places tray 6 on the three horizontal support plates 5 on the front, and starts the servo motor 7. The output shaft of the servo motor 7 drives the support plates 5 on the surface of the scraper conveyor 4. The conveying distance and pause time of the servo motor 7 are preset in advance via the PLC control cabinet 2. The preset conveying distance ensures that one of the support plates 5 is on the same horizontal line as the conveying system of the pulp molding dryer 1. The servo motor 7, controlled by the PLC control cabinet 2, drives the support plates 5 on the surface of the scraper conveyor 4 a certain distance and then automatically stops. At this time, the cylinder 9 is activated, and the air pressure is set via the PLC control cabinet 2. The waiting time between one cycle of the extension and retraction of the cylinder 9 output end and the next cycle action, wherein the pause time of the servo motor 7 is longer than the time of two cycles of the cylinder 9 output end, so that the output end of the cylinder 9 drives the push plate 10 to move to the right, so that the push plate 10 pushes the tray 6 onto the conveying system of the pulp molding dryer 1, and then the tray 6 enters the drying chamber of the pulp molding dryer 1 to dry the pulp molding wet preform in the tray 6. This achieves the purpose of pushing the tray containing the pulp molding onto the dryer through the feeding structure, thereby avoiding manual intervention in tray placement; it should be noted that the settings and control in the PLC control cabinet 2 are existing technologies and will not be described in detail here.
[0023] In summary, this rapid drying device for pulp molding achieves its purpose by placing a tray 6 containing wet pulp molding blanks on three horizontal support plates 5 on the front. The output shaft of the servo motor 7 drives the support plates 5 on the surface of the scraper conveyor 4 to move. After the servo motor 7 drives the support plates 5 a certain distance, it automatically stops. At this time, the cylinder 9 is activated, and the output end of the cylinder 9 drives the push plate 10 to move to the right. The push plate 10 pushes the tray 6 onto the conveying system of the pulp molding dryer 1, thereby allowing the tray 6 to enter the drying chamber of the pulp molding dryer 1 for drying of the wet pulp molding blanks in the tray 6. This achieves the goal of pushing the tray containing pulp molding blanks onto the dryer through the feeding structure, thus avoiding manual intervention in tray placement.
