Description

Technical Field

[0001] The invention relates to coconut processing equipment, in particular to an automatic young coconut processing machine. Background Art

[0002] Coconut is a perennial tropical woody oil crop of the genus Cocos in the palm family. The main product of the coconut tree is the coconut fruit, which is nearly spherical in shape and consists of the exocarp, mesocarp, endocarp, seed coat, coconut meat, coconut water and other parts. Green coconut, also known as green coconut, has a shorter fruiting cycle than yellow coconut. Coconut water is sweet and relieves heat and promotes salivation. Green coconut is freshest when it is picked, and the flesh tastes the most milky. The flesh is generally thin or thick, and is more suitable for making coconut jelly, coconut chicken soup and other foods than old coconut (hairy coconut). The green coconut food processing industry, which uses coconut meat and coconut water as raw materials, is an important pillar of Hainan's food processing. In summary, green coconut has a very huge economic value.

[0003] Ripe coconuts can be stored for a long time without special preservation, but young coconuts must be preserved because they are relatively fresh. In order to meet the demand for fresh coconuts from people far away from the place of production and facilitate the long-distance transportation and storage of coconuts, it is necessary to peel, soak and wrap the young coconuts. The most time-consuming and labor-intensive process is to peel the outer layer of the young coconuts and process them into a regular shape with a cylindrical main body and a spire at the top. Soaking and wrapping the young coconuts after processing can effectively extend their shelf life. Otherwise, its epidermis will age quickly, affecting the taste of the juice and pulp and reducing its nutritional value. At present, the machinery for processing young coconuts is relatively backward and mainly relies on manual cutting, which is time-consuming and labor-intensive, unsafe and unhygienic. This method has low processing efficiency, high labor costs, and is prone to personal accidents, which to a certain extent restricts the development of enterprises. Summary of the invention

[0004] The present invention is an efficient, safe and automatic coconut green processing equipment. The invention of the equipment can change the early process of coconut green processing - coconut green cutting and forming process from manual operation to machine operation, which can not only ensure the consistency of products, greatly improve production efficiency, and provide sufficient raw materials for later processes, but more importantly, it can ensure the personal safety of operators and reduce the occurrence of disability accidents. At the same time, since the process adopts automation, it can not only save a large number of labor forces, but also solve the bottleneck problem of coconut production enterprises expanding production scale, and open up new ways for enterprises to expand production scale and improve economic benefits.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a frame is provided, a coconut cutting device is provided at the front of the frame, a coconut grabbing manipulator is provided at the rear of the coconut cutting device, and a coconut bottom cutting device is provided at the lower part of the coconut grabbing manipulator.

[0006] The coconut cutting device is provided with a rotating motor, a rotating nail disk is installed on the rotating motor, a clamping cylinder is provided just above the rotating nail disk, a clamping flange is provided at the lower end of the clamping cylinder, and an integrated molded tool and an electric push rod are symmetrically provided above both sides of the rotating nail disk.

[0007] The one-piece cutter consists of a blade and a blade support.

[0008] Right below the one-piece cutter is a coconut peeling opening.

[0009] The coconut green grasping manipulator is provided with a screw-nut mechanism, wherein a screw in the screw-nut mechanism is connected to a stepping motor, a lifting cylinder is provided under the nut in the screw-nut mechanism, and a clamping jaw opening and closing cylinder and a clamping jaw are provided under the lifting cylinder.

[0010] The clamping jaw is provided with a clamping jaw bracket, and a gear and a rack for driving the clamping jaw to move are arranged in the clamping jaw bracket. The front part of the clamping jaw bracket is provided with a clamping jaw finger, and the clamping jaw finger is connected with the gear.

[0011] The coconut bottom cutting device is provided with a band saw motor, a band saw wheel disc is provided in front of the band saw motor, and a band saw blade is arranged on the band saw wheel disc.

[0012] A coconut cutting outlet is arranged below the saw blade of the band saw, and a coconut finished product discharge outlet is arranged at the rear lower part of the motor of the band saw.

[0013] During operation, the green coconut to be processed is placed vertically upward on the rotating nail plate, the piston rod of the clamping cylinder is extended, and the clamping flange is driven to move downward, and the green coconut to be processed is pressed down, so that the fixing nails on the rotating nail plate are inserted into the bottom of the green coconut to be processed, and then the piston rod of the clamping cylinder is retracted, driving the clamping flange to move upward and return to the initial position. After the green coconut to be processed is fixed, the rotary motor rotates, driving the rotating nail plate and the green coconut to be processed to rotate together. Then the electric push rods on both sides work at the same time, pushing the one-piece molded tool 4 to approach the green coconut to be processed at the same time, and cutting the side and top of the green coconut. The cut coconut green skin falls from the coconut green peeling and blanking ports on both sides under the action of gravity. After cutting is completed, the electric push rod is retracted, so that the two sets of tools are returned to the initial position at the same time, and the rotating motor stops.

[0014] Then the stepper motor is in forward transmission, and drives the lifting cylinder, the jaw opening and closing cylinder and the jaw installed below to move forward together through the screw nut mechanism. At the same time, the lifting cylinder piston rod is pushed out, and the piston rod of the jaw opening and closing cylinder is pushed out, pushing the rack to drive the gear to rotate, so that the jaw fingers open and stop on both sides of the processed coconut. Then, the piston rod of the jaw opening and closing cylinder retracts, pulling the rack to drive the gear to reverse, so that the jaw fingers close and firmly hold the coconut. Then the lifting cylinder piston rod retracts, driving the jaw and coconut to move upward together, so that the bottom of the coconut is separated from the rotating nail plate. Then the stepper motor reverses, and drives the lower jaw and coconut to move backward through the screw nut mechanism. When the coconut moves to the empty space between the nail plate and the band saw blade, it pauses, and the piston rod of the lifting cylinder extends to move the coconut downward, ready for bottom cutting. Start the band saw motor, drive the band saw blade to rotate through the band saw disc, and then the stepper motor continues to reverse, so that the coconut continues to move backward. When the bottom of the coconut contacts the band saw blade, the bottom of the coconut is cut off by the band saw blade and falls into the coconut bottom cutting opening. The processed coconut continues to move backward with the clamp to the top of the coconut finished product discharge port. The piston rod of the clamp opening and closing cylinder is pushed out, pushing the rack to drive the gear to rotate, so that the clamp fingers open, and the processed coconut falls into the coconut finished product discharge port, thus completing a working cycle.

[0015] The beneficial effects of the present invention are that the coconut green processing procedure is automated, the labor cost is reduced, the production efficiency is improved, and the foundation is laid for the production enterprises to expand the production scale; at the same time, the occurrence of personnel injury accidents is reduced; and the coconut green processing procedure is made efficient, safe and automatic.
