Description
Technical Field
The invention relates to the fields of fish processing, fry vaccine injection and classification, in particular to an automatic fry turning device.
Background
With the rapid development of the aquatic product industry, the popularization of new technologies such as industrialized aquaculture and the integration of upstream and downstream industrial chains, the requirements on production and processing automation are gradually increased.
The requirements for automation in the fields of fish processing, vaccine injection, classification and the like are gradually increased.
How to arrange the fry with the head facing to each direction into a state facing to a uniform direction in an automatic process is a precondition and a key for the success of mechanisms such as subsequent processing, vaccine injection, grading and the like.
At present, the fry is unified mainly by manpower. Before entering the processes of processing, vaccine injection, grading and the like, workers put the head or the tail of the fry into a machine forward according to the design requirements of the mechanism, however, the manual method has the defects of low efficiency and high cost.
In the prior art, the invention patent with application number 201410143355.6 discloses a fish head guiding device for fish vaccine injection, which can correct the bodies of fish fries to be parallel to the running direction of a conveyor belt and uniformly guide the fish fries to be in a state that the fish heads are forward.
Disclosure of Invention
The invention provides an automatic fry turning device, which aims to solve the problem that fries are arranged in a uniform orientation state in automatic fish processing procedures such as fish processing, fry vaccine injection, grading and the like.
The technical scheme adopted by the invention is as follows:
an automatic fry turning device comprises a conveyor belt, a fish baffle plate, a driving roller, a power transmission mechanism, a motor, a turning roller, a fish receiving baffle plate and a frame; one end of the conveying belt is connected with the driving roller, and the other end of the conveying belt is connected with the turning-over roller; the fish blocking plates are arranged on two sides of the conveyor belt; the fish receiving baffle is arranged below the turnover roller and is used for receiving fish conveyed from the conveyor belt; the driving roller is connected with the motor through a power transmission mechanism; the driving roller and the turning-over roller are both arranged on the frame.
In the technical scheme, furthermore, the radius of the turning-over roller is larger than or equal to the maximum curvature radius of the body contour curve when the fish to be turned over is laterally bent, so that the body of the fry is tightly attached to the surface of the conveyor belt in the whole turning-over process, and the fry is prevented from being separated from the conveyor belt in advance due to the fact that the radius of the turning-over roller is too small.
Furthermore, the end of the conveyor belt where the turnover roller is located is not lower than the end of the conveyor belt where the driving roller is located or is on the same horizontal plane. If the turning-over roller is in a low position, the fry is accelerated to move circularly when turning over, the centrifugal force is large, and the fry is easy to separate from the conveyor belt to cause failure of turning over; if the turnover roller is in a high position, the speed of the fry is low in the whole turnover process, the stress is good, and a liquid bridge formed between the fry and the conveyor belt is not easy to break. However, the static friction force of the conveying belt to the fry cannot resist the gliding force of the fry due to the excessively high relative position of the turnover roller, and the fry reversely slides along the moving direction of the conveying belt, so that the included angle between the conveying belt and the horizontal plane is smaller than the friction angle between the fry and the conveying belt material when the fry is wet.
Further, connect the fish baffle including connecing fish baffle main part and locating the side shield that connects fish baffle main part both sides, connect fish baffle main part by swash plate, bent plate, connecting plate consecutive obtaining, the connecting plate be located the top and link to each other with the frame.
Furthermore, the included angle between the inclined plate of the fish receiving baffle and the horizontal plane is larger than the friction angle between the fry and the selected material of the inclined plate when the fry is wet, so that the fry can stably slide on the inclined plate.
Furthermore, the included angle between any tangent plane of the curved surface of the curved plate of the fish catching baffle and the horizontal plane is larger than the friction angle between the fry and the selected material of the curved plate when the fry is wet, so that the fry can stably slide on the curved plate.
When the device is used for turning over the fry, the fry placed in the device is anesthetized to lose mobility, so that the fry is prevented from moving to cause damage to a liquid bridge system; the conveyor belt should be kept relatively wet so that a liquid bridge can be stably formed between the fish body and the conveyor belt. The fry should be physically oriented parallel to the direction of movement of the conveyor belt as it enters the apparatus of the invention (manual placement, or other automated means to adjust the fry's body orientation, such as the straightening mechanism of the invention patent application No. 201410143355.6, may be used).
The invention principle of the invention is as follows:
the automatic fry turning device utilizes the liquid bridge phenomenon, and realizes the turning of fries in different directions into a state that the heads of the fries are forward by designing the structure of the automatic fry turning device. Liquid bridges are now a common force for solid-liquid-solid systems. In the case of highly or completely wetted contacting solid surfaces, a thin layer of liquid exists between them, which is called a liquid bridge. The force of the liquid bridge pulling the solids on both sides is called the liquid bridge force. Liquid bridge force is the force that is overcome to pull two solids apart. From the aspect of characterization, the liquid bridge force is the action of surface tension generated by bending the surface of the liquid, and is formed by the mutual action of the cohesion of the liquid and the adhesion between the liquid and the solid in essence. The concave liquid level between the liquid and the air results in a pressure difference between the gas and the liquid, which pressure difference is directed from the convex surface to the concave surface, i.e. to the inside of the liquid. The liquid creates suction on both sides of the solid surface along the normal direction of the contact surface.
On the curved surface of the conveyor belt where the turnover roller is located, the larger area of the fish tail and the flatter surface enable larger liquid bridge force to exist between the fish tail and the conveyor belt, and the fish head is weak in liquid bridge force due to the fact that the contact area of the fish head is smaller and the curvature of the fish head is large. When the fish tail enters the curved surface of the turnover roller forward, the fish tail part is attached to the surface of the conveying belt without separation under the action of the liquid bridge force and continues to be attached to the conveying belt to move until the heavy head part tears the liquid bridge from the head part under the condition of smaller contact area after the fish head enters the curved surface of the turnover roller. The fish head is separated from the surface of the conveyor belt earlier, the fish fry drops downwards in the air, falls onto the fish receiving baffle and moves along the curved plate of the fish receiving baffle, and finally the fish fry is adjusted to be in a state that the head faces forwards and the tail faces backwards, so that the fish fry is turned over; if the fish head enters the turning-over roller forwards, the fish head is directly separated from the conveying belt, the tail part is further driven to be separated from the surface, the fish head is still in a head-down state when falling, and the direction of the fish head is changed by the fish receiving baffle plate and then the fish head also forwards. In this way, after passing through the turning mechanism, the fry in different orientations are adjusted to be in a head-forward state and sent to the lower mechanism.
Compared with the background art, the invention has the beneficial effects that:
1. the automatic fry turning-over device is designed by utilizing the curvature characteristics and the adhesion characteristics of fries, and can turn the fries in different directions into the fries with the heads facing forwards.
2. Compare in artifical the putting, this scheme of use is efficient, the success rate is high, with low costs and easily realize.
