[0022] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0023] The tea leaf forming machine of the present invention is as follows Figure 1 , 2As shown, it includes a support seat 1, on which a forming mechanism 3 for rolling tea leaves into shape and a conveying mechanism 4 for conveying the formed tea leaves to a tea collection tank 5 are provided. The forming mechanism 3 includes two rollers arranged up and down, which have rolled the tea leaves into shape. One side of the rollers is provided with an operating table 2 for convenient operation and placement of tea leaves to be formed. The operating table 2 is provided with a feeding seat 6 for introducing the tea leaves to be formed between the two rollers. When in use, tea leaves are introduced into the forming mechanism one by one through the feeding seat 6, and the tea leaves are rolled into a flat and long strip by the upper and lower rollers. After forming, the tea leaves fall onto the conveying mechanism and are conveyed to the collection tank 5 below. This tea forming mechanism has a simple structure, a small size, a low cost, a high tea forming rate, and is easy to operate and use.

[0024] In the present invention, Figure 2 As shown in the figure, the conveying mechanism 4 includes a conveyor belt 42, and a driving shaft 43 and a driven shaft 44 are respectively provided at both ends of the conveyor belt 42. The driving shaft 43 and the driven shaft 44 support and drive the conveyor belt 42 to form a ring structure. A main transmission wheel is provided on the driving shaft 43, and the output end of the motor is transmitted to the main transmission wheel through the main transmission belt 41. The main transmission wheel drives the driving shaft 43 to rotate, and the conveyor belt 42 realizes transmission. After being formed, the tea leaves fall onto the conveyor belt 42, and are transported forward to the front end of the conveyor belt 42. After being flipped and transported by the arc-shaped flipping action, they fall into the collecting trough 5 below. The tea leaves falling into the collecting trough 5 are piled and orderly discharged, which is convenient for taking and placing for drying.

[0025] In the present invention, Figure 2 , 3 As shown, a transmission wheel I is provided at one end of the driving shaft 43, and the transmission wheel I drives the transmission wheel II provided at one end of the driving roller 31 to rotate through a transmission belt. The driving roller 31 can be driven to rotate by the driving shaft 43, and the other end of the driving roller 31 opposite to the transmission wheel II is provided with a gear I, and the driven roller is provided with a gear II33 meshing with the gear I. This structural setting can realize the control of the operation of the conveying mechanism and the forming mechanism through one motor, and has a simple structure and good synchronization.

[0026] In the present invention, in order to facilitate the adjustment and control of the tea leaf forming effect, the tea leaf forming machine is also provided with a gap adjustment structure for adjusting and controlling the gap between the two pressing rollers. Figure 4 As shown in , the gap adjustment mechanism includes adjustment blocks 35 disposed at both ends of the upper pressure roller, and a gap adjustment rod 34 is disposed on the adjustment block 35. In the present invention, the driven pressure roller 32 is located at the top, and the gap adjustment rod 34 is threadedly connected with the adjustment block 35. By adjusting the gap adjustment screw 34, the gap between the upper driven pressure roller 32 and the lower active pressure roller 31 is controlled to achieve fine adjustment of the gap, so as to better obtain the desired tea forming effect.

[0027] In the present invention, Figure 2 , 3As shown, a conveyor belt adjustment mechanism for controlling and adjusting the tightness of the conveyor belt 42 is provided on both sides of the conveying mechanism 4. The support seat 1 includes a vertical plate 11 provided on both sides, and the conveyor belt adjustment mechanism includes an adjustment seat 46 provided on the vertical plate. The adjustment seats 46 on both sides are provided with adjustment screws 48 respectively passing through the two ends of the driven shaft 44 vertically. The adjustment screws 48 are threadedly matched with the ends of the driven shaft 44. An adjustment slot 47 is provided on the side wall of the adjustment seat 46. A fastening screw for positioning the position of the driven shaft 44 on the adjustment seat 46 is provided at the end of the driven shaft 44. During the use of the tea forming machine, if the conveyor belt 42 is too loose, it will affect the normal conveying process, and if it is too tight, it will affect its service life. The tightness can be controlled and adjusted by the adjustment mechanism to ensure the normal operation of the forming drum. By simultaneously adjusting the adjustment screws 48 on both sides to drive the position of the driven shaft 44 relative to the driving shaft 43, the fastening screw passes through the adjustment slot 47 and is connected to the end of the driven shaft 44. After adjusting to the appropriate position, the fastening screw can be tightened to achieve positioning.

[0028] In the present invention, the adjustment seat 46 is connected to both sides of the column 11 through the adjustment plate 7, and three vertically arranged adjustment slots 9 are provided on the adjustment plate 7. The screws pass through the adjustment slots 9 and are connected to the adjustment seat 46. The inclination angle of the conveyor belt can be controlled by adjusting the position of the screws in each adjustment slot 9 to facilitate the operation of the operator.

[0029] In the present invention, Figure 2 As shown in the figure, a cleaning cotton 36 for cleaning the pressing roller is provided on the pressing roller to clean the impurities on the surface of the pressing roller to ensure the quality of the pressing roller molding. The feed seat 6 is provided with a plurality of perforations for passing tea leaves, usually with one end of the tea stem passing toward the perforation, and the perforations are set as conical holes to facilitate the tea leaves to pass out and improve the tea leaves molding efficiency. The feed seat 6 is installed on the operating table 2 by screws, and two, three or more operating positions can be set on the operating table as needed, and a feed seat 6 is correspondingly set on each operating position.

[0030] In the present invention, a table support 8 for supporting the operating table 2 is provided on the support seat 1, and the operating table is detachably mounted on the table support by screws to facilitate the maintenance and cleaning of the tea forming machine. Preferably, protective covers are provided above the pressing roller of the tea forming machine, on the main transmission belt and on the side transmission belt to improve the safety of operation.

[0031] The tea leaf forming machine of the present invention has a simple structure, low cost, high tea leaf forming rate, is easy to operate and use, and has strong practicality and good application prospect.

[0032] The present invention is described above by way of example in conjunction with the accompanying drawings, but the present invention is not limited to the above manner. As long as various non-substantial improvements made using the method concept and technical solution of the present invention or direct applications to other occasions are made, they all fall within the protection scope of the present invention.
