Description

Technical Field

[0001] The present application relates to the field of food processing, and in particular to a driving device for a stamping die. Background Art

[0002] Printing molds are often used in the field of food processing. They are tools used to print patterns, words or logos on the surface of food, and are commonly used in the production process of cakes, candies, biscuits, chocolates and other foods. When using a printing mold, the food needs to be placed on the mold, and then a certain amount of pressure is applied to make the mold contact the food, so as to leave the desired pattern or words on the surface of the food, and then the food is removed from the mold after completion. The application of printing molds can improve the efficiency and quality of food processing, and also increase the beauty and attractiveness of food.

[0003] The related prior art is such as the Chinese patent application "An automatic pressing and demolding device for food processing", application number: CN202310426308.1; it discloses a device frame, a conveyor belt, an embossing part, and an oil brushing part; two conveyor belts are provided, and the two conveyor belts are arranged alternately on the front and rear sides of the device frame; an embossing part is provided inside the device frame for sliding up and down; an oil brushing part is coaxially sleeved on the upper part of the embossing part. The present invention adopts the embossing part to print on the upper and lower sides of the moon cakes, thereby improving the market competitiveness of the moon cakes and increasing the sales volume of the moon cakes; and the upper pressing template is driven by the upper pressing cylinder to automatically press and demold the moon cake fabric, thereby improving the production efficiency of the moon cakes; the flip template is used to rotate around the fixed template, and the rear half of the pressed moon cake fabric is suspended in the air, and then the moon cake fabric is slowly placed on the conveyor belt through the unloading cylinder, thereby completing the unloading of the moon cake fabric, preventing the pattern on the lower part of the moon cake from being destroyed due to impact, and ensuring the pressing effect.

[0004] With the continuous development of science and technology, the technology of printing molds will be further innovated and improved. The inventor of this application has made further improvements to the driving device of the die, extending the service life of the driving device and facilitating assembly and maintenance by operators.

[0007] Compared with the prior art, the advantage of the present application is that the up and down movement of the die frame is achieved through the rotating shaft, rotating motor, and transmission assembly, and printing on food can be achieved in cooperation with other components of the mold. By providing multiple sleeves and guide shafts, the movement stroke limit of the die frame is achieved, ensuring that the die frame moves up and down along a predetermined route.

[0014] In some embodiments of the present application, one end of the connecting rod is fixedly connected to the middle of the flip shaft, and the other end of the connecting rod is movably connected to the output shaft of the linear cylinder.
