Background technique

The tea stripping machine is one of the key equipment for green tea finishing and shaping. It has been widely used in the tea processing production line. The tea leaves are thrown, collided, rubbed, squeezed and other forces in the reciprocating U-shaped tank to make the shape. At the same time, corresponding physical and biochemical changes of tea leaves occur under the heat of the heating device: to inactivate the activity of polyphenol oxidase, evaporate part of the water, volatilize the smell of green grass, and soften the tissue; to achieve the purpose of finishing and shaping. In order to meet the requirements of different strip shapes (needle shape, flat shape, etc.), in the practice of tea making for many years, it is usually completed by placing a pressure rod in the U-shaped groove pot of the machine, but the release of the pressure rod and the Recycling still has to be done manually. While increasing the labor intensity, it is not conducive to the requirement of unmanned processing workshops for clean production of tea. In addition, the quality of tea processing is restricted by the technical experience of workers, which cannot achieve standardized production of tea. Requirements affect the quality of finished tea.

Contents of the invention

The purpose of the present invention is to solve the problem that manual operation is still required for pressurization and shaping of tea leaves, and automatic operation cannot be realized, and an electromagnetic automatic pressurization machine is provided to reduce labor intensity and can be used continuously with tea leaves. Chemical and clean production lines.

Its technical solution is: an electromagnetic automatic pressurization machine, including a frame, a heating unit arranged on the frame and a U-shaped groove pot composed of multiple U-shaped grooves supported by rollers, installed on a frequency conversion The drive sprocket on the output shaft of the motor is connected to the crank through the chain, and the connecting rod is hinged with the crank and the slider arranged on one side of the U-shaped pot, and it is characterized in that: the top of the inlet and outlet ends of the U-shaped pot is provided There are electromagnet brackets fixed on the four corners of the U-shaped pot. On the electromagnet bracket above the inlet and outlet ends of the U-shaped pot, electromagnetic coils corresponding to the two ends of the U-shaped slot of the U-shaped pot and the electromagnetic coils are installed. The controlled armature and the U-shaped groove of the U-shaped groove pot are respectively placed with pressure rods coated with steel plates at both ends.

Its technical effect is: the present invention is arranged on the electromagnetic coil in the electromagnet bracket above the U-shaped tank pot and the armature controlled by the electromagnetic coil, and according to the set program, utilizes the effect of electromagnetic force to place the U-shaped tank pot The two ends of the U-shaped tank covered with steel plates are automatically released and recovered, so as to control the pressurization time of the tea leaves in the U-shaped tank pot, and realize the automatic control of the pressure when the tea leaves are shaped; and by adjusting The speed of the frequency conversion motor is used to realize the frequency of the reciprocating linear vibration of the U-shaped tank pot; the scope of application of the machine and the types of tea making are enhanced, and the quality of the finished tea is improved, the labor intensity is reduced, and the processing of continuous and clean production of tea is realized. The requirement of unmanned workshop.

Detailed ways

As shown in Figures 1-4, an electromagnetic automatic pressure trimmer includes a frame 3, a heating unit 6 arranged on the frame and a U-shaped U-shaped groove composed of a plurality of U-shaped grooves supported by rollers 5. The grooved pot, the drive sprocket mounted on the frequency conversion motor 4 output shafts are connected by a chain crank 2, and the connecting rod 1 hinged with the crank and the slide block arranged on one side of the U-shaped grooved pot. The top of the U-shaped groove pot 7 import and export ends is provided with the electromagnet support 9 that is fixed on the four corners of the U-shaped groove pot, and on the electromagnet support above the U-shaped groove pot import and export end, a U-shaped groove with the U-shaped groove pot is installed. Electromagnetic coils 11 corresponding to both ends and armatures 10 controlled by the electromagnetic coils, and pressure rods 8 coated with 401 stainless steel plates at both ends are respectively placed in the U-shaped grooves of the U-shaped groove pot.

The center of the above-mentioned crank is above the straight line of the motion track of the U-shaped pot, and its distance is the eccentric distance, so that it has a better transmission angle and is beneficial to reduce machine vibration and noise.
