Description

Automatic Chestnut Cutting Machine

technical field

The invention relates to the technical field of chestnut cutting equipment, in particular to a fully automatic chestnut cutting machine.

Background technique

As a fast-selling product of chestnut products, sugar-fried chestnuts are strongly loved by consumers. In the process of making, it is necessary to make an incision on the surface of the chestnut to scratch the shell without hurting the meat. In order to allow consumers to peel off the shell easily and the meat is not easy to break, the incision surface must be in the center of the chestnut arc surface, and the incision position should be along the chestnut. In the length direction, the incision length is along the length direction plus the front and rear sides to achieve a complete opening. In the past, most chestnuts could only be cut by traditional handwork, and workers used knives to cut them by hand. Because the volume of chestnut is very small, it is not easy to fix, and it is easy to scratch the operator, and the efficiency of manual incision is low. So automatic chestnut cutting machines began to appear to replace manual chestnut cutting to improve work efficiency and work safety. However, the traditional chestnut cutting machine does not consider the chestnut incision surface and incision position, and the incision length cannot meet the above requirements, and there are problems such as chaotic opening directions and different opening lengths.

Contents of the invention

The present invention mainly provides a fully automatic chestnut cutting machine, which solves the problems that the chestnut cutting machine in the prior art does not consider the chestnut cutting surface and the cutting position, and the length of the cutting does not meet the above requirements, and there are messy opening directions and different opening lengths.

In order to solve the above technical problems, the present invention adopts the following technical solutions:

A full-automatic chestnut cutting machine, comprising a circular feeding mechanism, a horizontal distance and attitude adjustment mechanism installed at the output end of the circulation feeding mechanism, a rotary clamping mechanism installed at the output end of the horizontal distance and attitude adjustment mechanism, and a mechanism for cutting chestnuts. The floating cutting mechanism; the cycle feeding mechanism includes a first frame, a feeding chute is installed on the first frame, a hopper is installed at the lower end of the feeding chute, and a hopper is installed in the feeding chute A lifting assembly that drives a single chestnut to rise, a vertical attitude adjustment chute is installed on the first frame corresponding to the side of the feed chute, and a vertical attitude adjustment chute is installed on the upper end of the feed chute to the vertical attitude adjustment chute. A material guide plate for guiding materials, a vertical posture adjustment assembly for turning chestnuts is installed on the first frame corresponding to the position below the vertical posture adjustment trough, and a vertical posture adjustment component for driving chestnuts to move is installed in the vertical posture adjustment trough. The conveying assembly also includes a visual recognition camera for recognizing the vertical attitude of the chestnuts at the output position of the vertical attitude adjustment trough, and an air blowing assembly for blowing the chestnuts to fall into the hopper after the recognition. Wherein, the lifting component can adopt any one in the prior art, such as: a hoist, a lifting tray and other structures. As long as a single chestnut can be lifted in the feeding trough. The conveying component can adopt any one in the prior art, such as: a conveyor belt, etc., as long as the chestnut can be moved from the inlet end to the output end in the vertical attitude-adjusting trough. The air blowing assembly can adopt the prior art, as long as the chestnut can be blown. When in use, pour the chestnuts into the hopper, and the chestnuts fall into the feeding chute from the lower end of the hopper, and the lifting components installed in the feeding chute drive a single chestnut to lift, and then fall into the vertical adjustment through the material guide plate at the upper end of the feeding chute. In the attitude trough, the chestnut is driven to move by the transmission component in the vertical attitude adjustment trough, and the horizontal distance and attitude adjustment mechanism that moves from the inlet end to the output end can move through the vertical attitude adjustment trough. The vertical attitude adjustment component on a frame turns over the chestnuts in the vertical attitude adjustment trough, turns over the chestnuts with the curved surface facing downwards, and makes the plane of the chestnuts face downwards. Identify the chestnuts in the vertical posture adjustment trough by installing a visual recognition camera. If it is recognized that the plane of the chestnut is facing upwards, the chestnuts will be blown down by starting the air blowing component, so that the chestnuts with the plane facing upwards will fall into the hopper again. Feeding; when the chestnuts enter the horizontal distance adjustment mechanism, the distance between adjacent chestnuts can be adjusted through it, and finally move to the clamping station, and the chestnuts are clamped and moved by the rotating clamping mechanism, so that they can pass through the floating cutting mechanism Carry out the cutting of the cambered shell of the chestnut. This application can effectively prevent the chestnuts from being crowded and blocked in the feeding trough by lifting and feeding the chestnuts individually; the chestnuts are turned over by the vertical posture adjustment component, so that the curved surface of the chestnuts becomes the incision surface upwards, and the horizontal spacing is adjusted The mechanism and the rotating clamping mechanism control the incision position of the chestnut, so that the floating cutting mechanism can open the middle part of the chestnut arc surface, so that the incision can fully ensure the length of the incision from one end of the arc surface to the other end, and reduce the disorder of the opening direction.

Further, the vertical attitude adjustment assembly includes a swing wire support installed on the first frame, a swing wire installation frame rotatably connected between the swing wire supports, and a swing wire mounting frame installed on the first frame.
