The rotation control of carousel, the automatic drawing of patterns of tealeaves to and the tealeaves of tealeaves grinding apparatus are packed into through the cooperation more efficient of driving motor and pneumatic cylinder, automatic suppression, the automatic transport of tealeaves after the suppression is accomplished, overall structure is simpler, presses the tea efficiency higher, and the drawing of patterns breakage rate is lower, more automatic intelligent.

Through the design of the ejection part of the grinding tool, on one hand, accurate positioning after the turntable falls down is better realized, and the technical problems that the grinding tool in the prior art is poor in positioning accuracy and easy to damage by a hydraulic machine are well solved; on the other hand, the nondestructive automatic demoulding of the tea is realized. The safety coefficient is higher, and the life is longer.

The embodiment of the invention is directed to an automatic pressing machine, and only exemplifies an automatic pressing structure and a working principle, but the automatic pressing machine is not limited to the structure; the rotary table of the tea leaf pushing-out device can be modified into a rigid conveying belt with a supporting structure at the bottom, the rigid conveying belt is wound into a circle around the hydraulic press, holes of a tea leaf pressing grinding tool are formed in the rigid conveying belt, the tea leaf pressing grinding tool is fixedly installed on the holes of the rigid conveying belt, then a tea leaf pushing-out part is modified into a hydraulic rod, the point where the tea leaf pressing grinding tool at the rear end of the hydraulic press passes is arranged, after tea leaf pressing is completed, the tea leaf pressing grinding tool passes through the grinding tool pushing-out part, the hydraulic rod is started and pushed out upwards, tea leaves are pushed out to the upper portion from the barrel body, a tea leaf pushing-out part is also arranged at the position, and the tea leaf pushing-out part is pushed onto the conveying belt after being started. Although it is different from the technical solution of the present application, the structure can also implement the technical solution of the present application. Only because its pressure tea grinding apparatus support piece structure is complicated, compare this application carousel formula structure too complicated, occupation space is also great. But it is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
