The invention has the advantages that: according to the invention, multiple devices such as slicing, deodorization, air drying and baking are optimized, so that on one hand, the flow property among the devices is improved, and on the other hand, the structure of each device is optimized, so that the processing efficiency and the processing quality of each procedure are improved. The invention adopts the conveying device with the square circulating structure, realizes continuous air drying and baking and can also carry out circulating feeding.

Furthermore, in the slicing stage, the invention can complete continuous cutting of multiple rows and multiple columns of eels in one time period of the cutting process, and can ensure timely blanking of eel blocks after each cutting, thereby realizing the advantages of strong industrial processing water flowing property and high automatic cutting effect. The eel cutting machine adopts an oblique cutting mode to cut eels, can realize that the cut eels automatically slide out of the sliding plate under the action of gravity to finish blanking, and does not need manual blanking or special equipment for mechanical blanking compared with a horizontal plate in the prior art.

Secondly, because of the oblique cutting, the eel cutting process which has the cutting stability problem is more difficult to control. By adopting the movable clamping and limiting device, the eel can be clamped and limited in the clamping and limiting stage, the relative position stability of the eel in the inclined state and the sliding state of the sliding plate is ensured, after the eel is cut, the eel block still clamped by the cantilever is subjected to the jacking action of the ejector rod, the free end of the cantilever is bounced off from the clamping position, the first torsion spring is reset, and the eel block is in a free state after losing the downward pressing and clamping action of the cantilever and finishes blanking under the action of the self weight. Therefore, the movable clamping and limiting device has different functions in different eel cutting links, can play a good clamping and limiting function before cutting, and can be flicked from the clamped position in real time after cutting without influencing the blanking of eel blocks.

Thirdly, because the thread direction of the section matched with the left limiting part is opposite to the thread direction of the section matched with the right limiting part in the first screw rod, the synchronous increase or synchronous reduction of the width of the limiting channels of the plurality of limiting assemblies in the same cantilever can be met only by rotating the first screw rod forwards or reversely during operation, and the technical effect of quickly adjusting the width of the limiting channels according to different widths of eels can be realized.

Furthermore, in the first air drying stage, because the planetary gear set is arranged in the air drying main bin and is matched with the four-corner rotating piece with the structure, the net cage can be turned through the rotation of the planetary gears, so that the eel blocks in the net cage are turned over, the front and the back of the eel blocks can be subjected to the air drying effect of hot air, and the drying uniformity of the eel blocks is improved. The turning-over of the eel blocks can be realized by rotating the planet wheel in the air drying main bin, so that the mechanization of the turning-over is realized, and the technical problems of low efficiency, time consumption and the like caused by taking out the airing net and then manually turning over in the prior art are not needed. In addition, the machine for realizing turnover has simple structure and simple and convenient operation.

Secondly, the work continuity of the invention is strong, the traditional conveyer belt such as a belt, preferably a chain conveyer is combined with the net cage of the invention, the technical effect of air drying while putting the eel blocks into the net cage is realized, the feeding process and the air drying process are combined continuously, and the whole water flowing property of the production line is improved.

Thirdly, the traditional air drying bin is divided into an air purifying and filtering bin and an air drying main bin, dust and impurities in the air are filtered in advance through the air purifying and filtering bin, and then the clean air is conveyed into the air drying main bin, so that the cleanness of an air source for drying the eel fillets is improved. Because the flowing filter felt is adopted to replace a screen cloth in the prior art, on one hand, the filter felt can flow in the air purification filter bin all the time through the continuous work of the feeding roller and the winding roller, so that the filter felt adsorbed with impurities and dust can be moved out of the air purification filter bin in time and wound on the winding roller, and the impurities and dust in the filter felt are prevented from being excessively accumulated on the filter felt to influence the normal filtration; on the other hand, the filter felt filtered by the invention can be moved out of the air purification filter bin in time, so that the mode of replacing the filter element by replacing a screen in the prior art is abandoned, and the technical effect of automatically replacing the filter element on line without stopping the production and processing process is ensured.

Therefore, the movable clamping and limiting device has different functions in different eel cutting links, can play a good clamping and limiting function before cutting, and can be flicked from the clamped position in real time after cutting without influencing the blanking of eel blocks. In the first screw rod 153 of the present invention, the direction of the thread of the section of the first screw rod matched with the left limiting member 154 is opposite to the direction of the thread of the section of the first screw rod matched with the right limiting member 155, so that during operation, only by rotating the first screw rod 153 in the forward direction or in the reverse direction, the synchronous increase or synchronous decrease of the widths of the limiting channels of the plurality of limiting assemblies in the same cantilever 152 can be satisfied, and the technical effect of quickly adjusting the widths of the limiting channels according to the difference of the widths of eels can be realized.

In the first air drying stage, because the planetary gear set is arranged in the air drying main bin 332 and the four-corner rotating piece 3123 with the structure of the invention is matched, the net cage 3121 can be turned over through the rotation of the planetary gear 352, so that the eel blocks in the net cage 3121 are turned over, the front and the back of the eel blocks can be subjected to the air drying effect of hot air, and the drying uniformity of the eel blocks is improved. Because the turning-over of the eel blocks can be realized by rotating the planet wheel 352 in the air-drying main bin 332, the mechanization of the turning-over is realized, and the technical problems of low efficiency, time consumption and the like caused by taking out the airing net and then manually turning over in the prior art are not needed. In addition, the machine for realizing turnover has simple structure and simple and convenient operation. Secondly, the work continuity of the invention is strong, the traditional conveyer belt 311 such as a belt, preferably a chain conveyer is combined with the net cage 3121 of the invention, the technical effect of air drying while putting the eel blocks into the net cage 3121 is realized, the feeding process and the air drying process are combined continuously, and the whole water flow of the production line is improved. Thirdly, the traditional air drying bin 33 is divided into an air purifying and filtering bin 331 and an air drying main bin 332, dust and impurities in the air are filtered in advance through the air purifying and filtering bin 331, and then the clean air is conveyed into the air drying main bin 332, so that the cleanness of an air source for drying the eel fillets is improved. Because the flow type filter felt 342 is adopted to replace a screen cloth in the prior art, on one hand, the filter felt 342 can flow in the air purification filter bin 331 all the time through the continuous work of the feeding roller 341 and the winding roller 343, so that the filter felt 342 adsorbed with impurities and dust can be moved out of the air purification filter bin 331 in time and can be wound on the winding roller 343, and the impurities and dust in the filter felt 342 are prevented from being excessively accumulated on the filter felt 342 to influence the normal operation of filtration; on the other hand, the filter felt 342 after being filtered by the invention can be moved out of the air purification filter bin 331 in time, so that the mode of replacing the filter element by replacing a screen in the prior art is abandoned, and the technical effect of automatically replacing the filter element on line without stopping the production and processing process is ensured.

Example 2

As shown in fig. 11, 12 and 13, the present embodiment is different from the above embodiments in that the bottom surface of the free end of the cantilever 152 is an inclined surface 1521 that is low in the front and high in the rear. When the rear edge of the bottom surface of the free end of the cantilever 152 is in contact with the jack 16, the rear edge is flush with the top surface of the jack 16 or slightly higher than the top surface of the jack 16. The direction of the arrow in fig. 19 is the direction of the sliding plate 14.

Thus, when the rear edge of the bottom surface of the free end of the cantilever 152 moves to the position contacting with the top bar 16, the top bar 16 can continuously give an upward vertical component to the free end of the cantilever 152 until the cantilever 152 is pushed away from the bottom plate 12 as the slide plate continues to move downward and obliquely rearward due to the inclined surface 1521 of the bottom surface of the free end of the cantilever 152 that is lower in front and higher in rear. Because the thicknesses of different batches of eels are greatly different, as shown in fig. 14, in the invention, the bottom of the fixing seat 151 is provided with a lifting mechanism, which can be an air cylinder or other prior art to adjust the height of the fixing seat 151, the lifting mechanism can be a sliding plate 14 provided with a fixed screw 1105, the fixing seat 151 is sleeved in the fixed screw 1105, the bottom of the fixing seat 151 is supported by a nut 1106 matched with the fixed screw 1105, and the nut 1106 is rotated to realize the up-and-down movement of the nut 1106 and drive the up-and-down movement of the fixing seat 151. In order to improve the stability of the fixing base 151, the nut 1106 includes an upper nut 11061 and a lower nut 11062, wherein the lower nut 11062 is used to support the bottom of the fixing base 151, the upper nut 11061 is located above the fixing base 151, and the upper nut and the lower nut act simultaneously to clamp the fixing base 151. The height of the cantilever 152 is adjusted through the lifting mechanism, so that the eel with different thicknesses can be clamped. In this way, the engaging groove or the protrusion provided on the bottom plate 12 for engaging with the free end of the cantilever 152 is configured to move up and down, and specifically, the engaging groove or the protrusion can move up and down by the above-mentioned lifting mechanism. The top rod 16 of the present invention can be a screw rod, and is in threaded fit with the bottom plate 12, and the height of the screw rod exposed out of the bottom plate 12 is adjusted by rotating the screw rod. The invention can meet the matching requirement of the cantilever 152 and the mandril 16 by optimizing the structure of the free end of the cantilever 152, and has the technical effects of simple structure, high efficiency and quickness in work.

As shown in fig. 15, the present embodiment is different from the above embodiments in that the push rod 16 is driven to reciprocate vertically by the first transmission mechanism, and the upward movement of the push rod 16 can push the free end of the cantilever 152 in the engaged state to be separated from the base plate 12. Cutting device 11 includes cutting knife 111, cutting knife base 112, second drive mechanism, and the one end and the cutting knife base 112 of cutting knife 111 are articulated, and the other end of cutting knife 111 is the free end, and the free end of cutting knife 111 is connected with second drive mechanism from left to right or from right to left to span the slip orbit of slide 14 to drive cutting knife 111 luffing motion through second drive mechanism. The first transmission mechanism comprises a first guide sleeve 171, a first connecting rod 172, a second connecting rod 173 and a first rotating wheel 174, the upper end of the first connecting rod 172 is connected with the ejector rod 16, the lower end of the first connecting rod 172 penetrates through the first guide sleeve 171 from top to bottom to be hinged with one end of the second connecting rod 173, and the other end of the second connecting rod 173 is eccentrically hinged with the first rotating wheel 174. The second transmission mechanism comprises a second guide sleeve 175, a third connecting rod 176, a third connecting rod 177 and a second rotating wheel 178, the upper end of the third connecting rod 176 is connected with the free end of the cutting knife 111, the lower end of the third connecting rod 176 penetrates through the second guide sleeve 175 from top to bottom to be hinged with one end of the third connecting rod 177, and the other end of the third connecting rod 177 is eccentrically hinged with the second rotating wheel 178. The first rotating wheel 174 is connected to the second rotating wheel 178 by a belt or a chain.

According to the invention, the second rotating wheel 178 is driven to rotate by the rotating wheel motor, the second rotating wheel 178 rotates to drive the third connecting rod 177 connected with the fourth connecting rod to transmit, the third connecting rod 176 is driven to move up and down in the second guide sleeve 175, and then the free end of the cutting knife 111 is driven to swing up and down, when the third connecting rod 176 moves to the highest point, the opening of the cutting knife 111 is the largest, and when the third connecting rod 176 moves to the lowest point, the knife head of the cutting knife 111 contacts with the sliding plate 14, so that one-time cutting work is completed. Meanwhile, the second rotating wheel 178 rotates to drive the first rotating wheel 174 to rotate, and the first rotating wheel 174 rotates to drive the second connecting rod 173 to transmit, so as to drive the first connecting rod 172 to move up and down in the first guiding sleeve 171, and further drive the top rod 16 to move up and down. When the rear side of the free end of the cantilever 152 moves to a position right above the ejector rod 16, the ejector rod 16 moves upwards just to a position contacting with the bottom of the free end of the cantilever 152, the ejector rod 16 continues to move to eject the free end of the cantilever 152 from a clamping or attracting state, and the ejector rod 16 is at the highest point when the ejector rod is ejected.

The difference between this embodiment and the above embodiment 2 is that the way the ram 16 pushes the cantilever 152 open is based on the active extension movement of the ram 16. And the movement of the ejector rod 16 and the movement of the cutting knife 111 in the embodiment are continuously matched through the transmission system of the invention, so that the sequential operation of cutting and blanking is ensured. Compared with the passive ejection type of the embodiment 2, the technical effect of ejecting through the active movement of the ejector rod 16 is that enough ejection force can be provided. Compared with the mode of cutting by rotating a milling cutter or a round cutter in the prior art, the cutting mode of the invention adopts a guillotine type cutting mode, and can reduce the problem of splashing of blood flowing out of the fish body in the cutting process.

As shown in fig. 16, in addition, since the second guiding sleeve 175 is vertically arranged in the above embodiment, when the sliding plate 14 is tilted, it cuts the fish on the sliding plate 14 obliquely, i.e. the cutting surface of the fish is tilted. In order to achieve a parallel horizontal plane of the cutting surface of the fish, the second guide sleeve 175 may be arranged at an angle of inclination which corresponds to the angle of inclination of the slide 14, i.e. the second guide sleeve 175 is perpendicular to the slide 14 in the inclined state. Thus, the fixing seat 151 and the cutting blade 111 also need to be inclined correspondingly.

A blanking sloping plate 101 is provided behind the sliding track of the sliding plate 14. The base plate 12 is pivotally moved by a telescoping mechanism such as a pneumatic cylinder 1102.

The second screw 181 of the present invention is preferably driven by a servo motor 182. Since the cutting operation of the present invention is preferably performed when the sliding plate 14 and the cutting blade 111 are relatively stationary in the horizontal direction, the present invention is provided with a first proximity switch (not shown) behind the cutting device 11, when the cantilever 152 moves to a position corresponding to the first proximity switch, the first proximity switch sends a signal to the numerical control center, and after the numerical control center analyzes the signal, the first proximity switch sends a signal to the servo motor 182, the servo motor 182 stops working, and the sliding plate stands still. After the cutting knife 111 finishes one cutting, that is, the knife edge of the cutting knife 111 contacts with the sliding plate, the free end of the cutting knife 111 is close to a second proximity switch (not shown in the figure), the second proximity switch sends a signal to the numerical control center, the numerical control center sends a signal to the servo motor 182 after analyzing the signal, and the servo motor 182 starts to work again.
