Description

Technical Field

[0001] The invention relates to tea leaf forming equipment, which is used for shaping tea leaves into pieces with fixed shapes and belongs to the field of tea leaf processing equipment. Background Art

[0002] Traditional tea-forming machines are generally pneumatic devices with a cylinder installed in the middle to provide a power source and four guide rods around them. They use molds to squeeze the tea leaves into tea balls. This type of machine is generally used to make large tea cakes.

[0003] When making small tea balls, the cylinder must return after being pushed out before it can be pushed out again. This is an intermittent operation with low efficiency. In addition, the cylinder outputs a fixed speed and force, which affects the quality of the tea balls. Summary of the invention

The central shaft is fixed at the center of the frame I. Cam II is mounted and fixed on the central shaft and is located above the frame I. The worm wheel is mounted on the central shaft through a bearing and is located above the cam II. The disc is mounted on the central shaft through a bearing and fixed on the top of the worm wheel. Cam I is mounted and fixed on the central shaft and is located above the disc. More than 10 ejector rod holes II are opened through the lower part of the disc and the worm wheel. The upper ends of more than 0 ejector rods II are respectively placed in more than 10 ejector rod holes II, the spring II is sleeved on the ejector rod II and is located between the bottom of the worm gear and the cam II, the bottom end of the ejector rod II is a spherical bottom end and the spherical bottom end is always in contact with the upper surface of the cam II; more than 10 ejector rod holes I are opened on the upper part of the disc, the lower ends of more than 10 ejector rods I are respectively placed in more than 10 ejector rod holes I, the spring I is installed on the ejector rod I and is located between the top of the disc and the cam I, the top end of the ejector rod I is a spherical top end and the spherical bottom end is always in contact with the lower surface of the cam I;

[0006] Cam I is composed of wheel I, wheel II, and wheel III connected in sequence. Cam I is provided with a slot I. The bottom surfaces of wheel I and wheel III are arc-shaped. Idle wheel I is movably arranged on one end of shaft I through a bearing. Idle wheel I is fixed to the upper part of frame II through shaft I. Idle wheel I is arranged in slot I. A hopper is arranged on one side of wheel II. The hopper outlet is located above ejector hole II. Idle wheel II is movably arranged on one end of shaft II through a bearing. Idle wheel II is fixed to the lower part of frame II through shaft II. Cam II is provided with a slot II. Idle wheel II is arranged in slot II. A protrusion on cam II is arranged below the entrance of the discharge trough. A receiving trough is arranged below the discharge trough.

[0007] The transmission mechanism includes a worm gear, a pulley, a belt, and a motor. Both ends of the worm gear are arranged on the frame II through bearings and are located above the idler wheel II. The pulley is fixed on one end of the worm gear. The pulley is connected to the output end of the motor through a belt. The motor is fixed at the lower part of the frame I. The worm gear is meshed with the worm wheel and drives the worm wheel to rotate.

[0008] The disc comprises disc I, disc II and disc III, disc II is fixed between disc I and disc III, a push rod hole I is opened on disc I, and a push rod hole II is opened through disc III and the worm wheel.

[0009] A shell is arranged at the lower part of the forming mechanism, and a hopper is fixed on the shell, and an outlet of the hopper is located above the ejector hole II.

[0010] The discharging trough comprises a baffle and a bottom plate with holes, wherein the baffles are arranged on both sides of the bottom plate, and one end of the baffle is arranged above the tray III for collecting the formed tea leaves into the discharging trough.

[0011] A shell is arranged outside the pulley, the belt and the motor.

When wheel Ⅱ transitions to idler wheel Ⅰ and idler wheel Ⅱ, the gap between push rod Ⅰ and push rod Ⅱ is the smallest, which is the shape of tea ball; when the hole is turned to the discharge port, push rod Ⅰ retreats, and push rod Ⅱ pushes the formed tea ball out of push rod hole Ⅱ under the action of the convex block on cam Ⅰ, and flows out of the discharge chute under the action of the baffle; a hole is opened on the bottom plate of the discharge chute, and broken tea and unformed tea leaves leak into the receiving chute from the hole; this process is repeated, and push rod Ⅰ and push rod Ⅱ continuously repeat the same operation in push rod hole Ⅰ and push rod hole Ⅱ, forming a tea-making equipment assembly line.

[0015] The device of the present invention uses a motor as a power source and realizes tea feeding, tea ball forming, tea ball ejection and tea dust recovery through the coordination of the actions of a worm, a worm wheel, a cam, a spring, a push rod and the like. The device of the present invention has a simple structure, is easy to operate, has reliable equipment performance, high production efficiency and good product quality, and is suitable for industrial production and market promotion and application.
