Description

Technical Field

[0001] The utility model relates to the technical field of celadon processing, in particular to an automatic rolling device for Longquan celadon clay blanks. Background Technique

[0002] Celadon processing refers to the entire technological process of making celadon, which encompasses a series of complex and delicate steps aimed at transforming raw materials into exquisite celadon artworks or daily necessities. Celadon processing includes the following aspects:

[0003] Raw material preparation: The first step in celadon processing is the preparation of raw materials. This includes selecting suitable porcelain clay (such as kaolin), glaze (high-temperature lime glaze with calcium oxide as the main flux and containing an appropriate amount of iron oxide), and other auxiliary materials. Through means such as crushing, grinding, washing, and refining, these raw materials are processed into blank materials and glaze materials suitable for various forming methods and glazing methods. Forming: Forming is a key link in celadon processing, which determines the final shape and size of celadon. Traditional forming processes mainly use methods such as throwing, molding, and hand-sculpting, while modern processes have gradually introduced new technologies such as mechanical die pressing and slip casting. These methods can produce celadon blanks in various shapes such as bowls, plates, cups, and bottles. Air-drying and trimming the blank: The freshly formed wet blank contains a large amount of moisture and needs to be air-dried to reach a certain hardness for subsequent processes such as trimming and glazing. Air-drying can be carried out by various methods such as natural drying or drying. Trimming is to trim the air-dried blank to make its surface delicate, smooth, and of uniform thickness, and operate on components such as bottom feet, ears, spouts, and handles according to needs. At the same time, decorative techniques such as scratching, engraving, and printing are often completed during the trimming process.

[0004] However, in actual use of the existing technology, Longquan celadon is world-famous for its unique glaze color and exquisite craftsmanship. In the production process of Longquan celadon, the forming of the clay blank is a key link. Traditional celadon clay blank forming usually uses the method of manual rolling. However, when processing celadon with simple shapes and large quantities, the manual rolling forming method not only has a high labor intensity but also low efficiency, making it difficult to meet the requirements of modern production.

[0027] Working principle: When in use, the utility model places the celadon clay blank to be rolled on the inner bottom of the rolling die 26. When the celadon clay blank is placed on the inner bottom of the rolling die 26, the adjusting screw rod 24 is synchronously rotated through the knob. When the adjusting screw rod 24 rotates, it will move inward due to the acting force generated by the threaded connection. When the adjusting screw rod 24 moves inward, it will drive the clamping piece 25 to move inward. When the clamping piece 25 moves inward, it will clamp and fix the rolling die 26. When the rolling die 26 is clamped and fixed, the third driving motor 20 is controlled to be turned on. When the third driving motor 20 is turned on, it will drive the rotating bottom column 21 to rotate. When the rotating bottom column 21 rotates, it will drive the rotating base 22 to rotate.

[0028] When the clamped and fixed rolling die 26 rotates horizontally, by controlling the first driving motor 7 to start. When the first driving motor 7 starts, it will drive the first synchronous pulley 8 to rotate. When the first synchronous pulley 8 rotates, it will drive the second synchronous pulley 9 to rotate through synchronous belt transmission. When the second synchronous pulley 9 rotates, it will drive the transmission screw rod 4 to rotate. And the external curved surface threads at both ends of the transmission screw rod 4 face in opposite directions, so that when the transmission screw rod 4 rotates, due to the acting force generated by screw connection, it will drive the upper L-shaped moving table 5 and the lower L-shaped moving table 10 to move linearly inward synchronously along the external curved surface of the limit slide rod 6. When the upper L-shaped moving table 5 and the lower L-shaped moving table 10 move linearly inward synchronously, they will drive the horizontally rotating rolling die 26 and the rolling head 16 to move linearly inward synchronously. When the horizontally rotating rolling die 26 and the rolling head 16 move linearly inward synchronously, the celadon clay blank inside the rolling die 26 can be rolled by the rolling head 16, thus realizing the function of facilitating the rolling operation of the celadon clay blank;

[0029] Meanwhile, by controlling the electric telescopic rod 17 to start. When the electric telescopic rod 17 starts, it will drive the rolling seat 15 to swing back and forth. When the rolling seat 15 swings back and forth, it will drive the rolling head 16 to swing back and forth for adjustment. By controlling the second driving motor 11 to start, when the second driving motor 11 starts, it will drive the first transmission gear 12 to rotate. When the first transmission gear 12 rotates, it will meshingly drive the second transmission gear 13 to rotate. When the second transmission gear 13 rotates, it will drive the rotating ejector pin 14 to rotate. When the rotating ejector pin 14 rotates, it will drive the rolling seat 15 to rotate. When the rolling seat 15 rotates, it will drive the rolling head 16 to adjust the horizontal rotation angle. Thus, while the celadon clay blank is being rolled, it is convenient to swing back and forth and adjust the rolling angle horizontally.
