Technical Field

The invention belongs to the technical field of brick tea production equipment, and relates to a turnover type discharging mechanism on a tea steaming production line.

background

In the brick tea production process, it is very key step to evaporate tea, evaporates numerous factors such as the precision of tea time, the play tea opportunity after evaporating tea, the cleanliness of tea box play tea after, directly influences the quality of brick tea and the quality of brick tea, and the tradition evaporates the tea production line and adopts artifical title tea pan feeding, artifical tea pouring, artifical the moving to the suppression transfer chain, and manual operation's non-standardization, uncontrollable nature and difference influence brick tea quality and production efficiency.

The tea steaming production line has the advantages that the tea steaming production line is comprehensively improved and reformed to meet the requirements, the tea steaming time can be adjusted, the tea steaming production line can be accurately fed (the tea leaves after the tea steaming are immediately required to enter a pressing die for pressing, otherwise the temperature is easily reduced, and the tea leaves are overcooked, The mutual viscosity can be reduced, the brick tea is not pressed tightly, the taste is poor, the tea pulp is lost and the like), the full-automatic blanking, the tea box is free from cleaning (can be recycled and reused online) and the like.

Disclosure of Invention

The invention aims to provide a turnover type blanking mechanism on a tea steaming production line aiming at the problems in the prior art, and the technical problem to be solved by the invention is how to thoroughly blank and avoid tea leaves from adhering to the inner wall of a tea box.

The purpose of the invention can be realized by the following technical scheme: the turnover type discharging mechanism on the tea steaming production line is characterized in that the tea steaming production line comprises a machine base, a tea steaming box, a receiving hopper, a lower fixed rail fixed in the tea steaming box and a plurality of tea boxes sliding on the lower fixed rail, wherein the lower fixed rail comprises a plurality of lateral supporting rods which are transversely arranged and fixed on the tea steaming box;

The tea box comprises a box body II with an upper opening and a lower opening, two guide plates symmetrically distributed on two opposite inner side surfaces of the box body II are fixedly arranged in the box body II, the outer end of each guide plate is connected with an arc-shaped bent plate, a cylinder is rotatably connected on the box body II between the two arc-shaped bent plates, the peripheral surface of the cylinder is matched with the two arc-shaped plates, the cylinder is of an incomplete cylindrical structure with a notch formed in the axis direction, two ends of the cylinder are rotatably connected to the box body II through a pin shaft respectively, and a torsion spring for driving the notch of the cylinder to face the upper opening of the box body is arranged between the box body II and the pin shaft; the cylinder, the connecting plate and the arc-shaped bent plate cover the opening at the lower end of the box body II when the torsion spring is not under the action of external force; a gear is fixedly arranged on the pin shaft, two sides of each gear are respectively provided with at least two shaft sleeves which are rotatably connected to the second box body, and the shaft sleeves extend out of the gears; the peripheral surfaces of the guide plate, the arc-shaped bent plate and the cylinder are all of grid structures;

The blanking mechanism comprises a first step surface and a second step surface which are arranged on the lateral supporting rod, the first step surface is matched with the shaft sleeve, the second step surface is matched with the gear, and a rack which can be meshed with the gear is arranged on the second step surface which is positioned above the material receiving hopper.

Under the scheme, the tea box is matched with the blanking mechanism for use, the tea box is supported by the shaft sleeve and the first step surface in the process of moving on the lower fixed track except the material receiving hopper, the bottom supporting rod is not arranged in the scheme, the bottom of the tea box is wide, when the tea box moves to the position of the material receiving hopper, the gear is meshed with the rack, the cylinder rotates, the restoring force of the torsional spring is overcome, the lower end opening of the box body II which is originally closed by the cylinder, the connecting plate and the arc-shaped bent plate is gradually opened, tea leaves in the box body II are poured out, in the pouring-out process, one side edge part of the cylinder moves downwards, the other side edge part moves upwards, the tea leaves are not extruded, the tea leaves are prevented from being blocked at a movable part, the damage of tea leaves caused by extrusion is avoided, the tea leaves in the box body II sequentially break away from the contact with the two arc-shaped bent plates, the whole tea leaves in, the gear is separated from the meshing with the rack, the torsion spring drives the cylinder to reset under the action of restoring force, and the bottom opening of the second box body is closed again.

In the above scheme, the radian of the cylinder is less than 180 degrees, an inclination angle of less than 70 degrees is formed between the side wall of the second guide plate and the side wall of the second box body, and the radian of the arc-shaped bent plate is less than 60 degrees, so that the arrangement has the following advantages: the steam contact area at the bottom of the tea box is greatly increased, the tea steaming efficiency is improved, the tea box running speed can be increased, and the tea steaming efficiency is improved; the arc-shaped bent plate has no dead angle capable of storing tea, no dead angle allowing the tea to be poured out exists between the guide plate and the inner wall of the box body II, the amount of the tea reserved in the tea box is very small, the repeated steaming amount of the tea is small, and the quality of brick tea is improved; the torsion spring acts on the tea box in the instant torque of the torsion spring in the resetting process of the cylinder, and the vibration exists between the cylinder and the tea box, so that the tea leaves remained in the tea box can fall out due to the vibration, and the possibility of the tea leaves adhering in the tea box is further reduced.
