[0001] This utility model relates to the field of metal sheet printing technology, and in particular to drying equipment for metal sheet printing. [Background Technology]
[0002] Metal sheet printing is commonly used for label and advertising printing on metal containers. It includes printing and drying steps. After the pattern is printed on the surface of the metal sheet, it is transported to a dryer for drying to maintain the stability of the pattern. When the metal sheet is lifted from the receiving rack on the drying device after printing, it is prone to collisions with the rack due to the inertia of the conveyor belt on the printing press. This can cause chipped corners or cracks in the metal sheet, affecting the yield of subsequent processing. [Utility Model Content]
[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a drying device for printing on thin metal sheets, so as to solve the problem of easy bumping during the conveying of existing thin metal sheets in production lines.

Detailed Implementation Methods
[0018] This utility model provides a drying device for printing on thin metal sheets. To make the purpose, technical solution and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and examples.
[0019] In the description of this utility model, it should be understood that the terms "top" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0020] like Figure 1-3 As shown in the embodiment of this application, a drying device for printing on thin metal sheets is proposed, including an oven 1, a conveyor belt 2, multiple flower racks 3, a lifting device 4, and a buffer device 5. The conveyor belt 2 is installed inside the oven 1, and the multiple flower racks 3 are arranged around the conveyor belt 2. The lifting device 4 is located adjacent to the conveyor belt 2 at the feeding end of the oven 1, and the buffer device 5 is located between the lifting device 4 and the conveyor belt 2.
[0021] This utility model discloses a drying device for printing on thin metal sheets, including an oven 1, a conveyor belt 2, multiple printing racks 3, a lifting device 4, and a buffer device 5. The printed thin metal sheets are conveyed by the conveyor belt to a side near the inlet of the oven 1. The lifting device 4 lifts the side of the thin metal sheet closest to the oven 1 and places it on the buffer device 5. The buffer device 5 slows down the movement of the thin metal sheet until it stops. The conveyor belt 2 drives the multiple printing racks 3 to rotate, and any one of the printing racks 3 holds the thin metal sheet on the buffer device 5. The device elevates the metal sheet to prevent it from directly impacting the conveyor belt 2 or the flower rack 3 on the printing press. Simultaneously, the lifting device 4 can directly lift the metal sheet onto the buffer device 5, preventing collisions caused by the buffer device 5 being higher or level with the printing press's conveyor belt, and avoiding situations where the buffer device 5 is lower than the printing press's conveyor belt, resulting in poor buffering effect. The drying equipment disclosed in this application ensures the smooth transfer of the metal sheet, avoids collisions, and improves the yield rate of metal sheet printing.
[0022] The buffer device 5 includes a swing frame 51, a swing plate 52, a deceleration mechanism 53, and multiple rollers 54. The swing frame 51 is located at the feeding end of the oven 1. The swing plate 52 is connected to the swing frame 51. The deceleration mechanism 53 and multiple rollers 54 are respectively located on the side of the swing plate 52 facing away from the swing frame 51. The multiple rollers 54 are arranged along the length of the swing plate 52. Since the buffer device 5 is higher than the conveyor belt of the printing machine, when the metal sheet is placed on the conveyor belt of the printing machine and the buffer device 5, the metal sheet is in an inclined state. The angle of the swing plate 52 is adjusted by the swing frame 51 so that the swing plate 52 is always in contact with the metal sheet. The multiple rollers 54 convert the sliding friction between the metal sheet and the swing plate 52 into rolling friction to avoid scratching the metal sheet. The deceleration mechanism 53 gradually reduces the moving speed of the metal sheet until it stops to prevent the metal sheet from colliding with the conveyor belt 2 or the flower stand 3.
[0023] The deceleration mechanism 53 includes multiple deceleration mechanisms 53 arranged sequentially along the length of the swing plate 52. Each deceleration mechanism 53 includes an air pump, an air extraction pipe, and a connecting cylinder. The air extraction pipe connects the air pump and the connecting cylinder. The connecting cylinder is inserted into the swing plate 52. The air inlet of the connecting cylinder is located on the side of the swing plate 52 facing away from the swing frame 51, drawing away the air between the metal sheet and the swing plate 52 to create a pressure difference between the metal sheet. The connecting cylinder includes a straight section and a frustum section. The straight section is inserted into the swing plate 52, and the smaller diameter end of the frustum section is connected to the straight section, increasing the negative pressure range formed by the air extraction end and further improving the deceleration effect.
[0024] The buffer device also includes a protruding edge 55, which surrounds the edge of the swing plate 52 on the side facing away from the swing frame 51. This reduces the distance between the metal sheet and the outer edge of the swing plate 52, reduces the amount of air entering, facilitates the formation of a negative pressure chamber, and increases the air pressure difference on both sides of the metal sheet. The swing frame 51 includes a base 511, two telescopic rods 512, and two hinges 513. The two telescopic rods 512 are respectively located on both sides of the base 511. One end of each of the two hinges 513 is connected to one of the two telescopic rods 512. The two hinges 513 are respectively connected to the swing plate 52, independently controlling the extension and retraction length of the two telescopic rods 512. The two hinges 513 drive the two ends of the swing plate 52 to rise or fall respectively, adjusting the tilt of the swing plate 52.
[0025] The lifting device 4 includes a lifting base 41, an extension rod 42, and multiple roller sets 43. The extension rod 42 is mounted on the lifting base 41, and the multiple roller sets 43 are mounted on the extension rod 42 along its length. The lifting base 41 drives the extension rod 42 and the multiple roller sets 43 on the extension rod 42 to rise. The multiple roller sets 43 lift the metal sheet, and the metal sheet and the multiple roller sets 43 roll against each other to avoid scratching the metal sheet.
[0026] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
