[0002] Eels usually need to be frozen as soon as possible after they are at their freshest and have been processed (such as slaughtered and cleaned) to maintain their quality and extend their shelf life. They should also be packaged after freezing to maintain their freshness and taste.

[0003] A Chinese patent with publication number CN216204596U was searched and it was found that a quick-freezing device for grilled eels was disclosed.

[0004] The utility model comprises a frame, wherein a first conveyor belt and a second conveyor belt are respectively arranged in the frame, a freezing bin is arranged on the first conveyor belt and the second conveyor belt, a liquid nitrogen quick freezer is arranged on the freezing bin, a cleaning mechanism is also arranged on the first conveyor belt, the cleaning mechanism comprises a fixed plate arranged above the first conveyor belt, a water distribution pipe is arranged at the bottom of the fixed plate, and a plurality of high-pressure cleaning nozzles are opened at the bottom of the water distribution pipe. By adopting the above technical scheme, eels are placed on the first conveyor belt, and the first conveyor belt conveys the eels to the cleaning mechanism and the freezing bin in turn, and the eels are cleaned by the high-pressure cleaning nozzles. After cleaning, the eels enter the freezing bin, and the upper surface of the eels is quickly frozen by the liquid nitrogen quick freezer, and then the eels are turned over by the turning mechanism and fall on the second conveyor belt, and the bottom surface of the eels is quickly frozen by the liquid nitrogen quick freezer on the second conveyor belt, thereby realizing quick freezing of both sides of the eels.

[0005] However, the patent has the following problems: the patent technology increases the comprehensiveness of freezing, so that seafood can be completely frozen on both sides to keep fresh, but it is impossible to drain the water during freezing, and the water adhering to the surface of the eel will form a thicker ice layer, which affects the later weighing accuracy and increases the calculation amount of packaging and transportation. Therefore, those skilled in the art provide an eel freezing and packaging integrated machine to solve the problems raised in the above background technology. Utility Model Content

[0006] The utility model aims to provide an eel freezing and packaging integrated machine, which has the advantage of being able to drain the cleaned eels, and solves the problem that the surface water of the eels cannot be drained when they are frozen, thus affecting the weighing weight.

[0007] The utility model provides the following technical solution: an eel freezing and packaging integrated machine, comprising a draining mechanism, a freezing mechanism and a packaging machine arranged in sequence from left to right;

[0008] The drainage mechanism comprises a support platform, on which a plurality of transmission rollers are arranged to rotate from left to right, on which a belt is arranged, and the transmission rollers are driven by a first motor arranged on the support platform to drive the belts;

[0009] A mounting frame is fixed above the middle of the support platform, and a fan is provided on each of the left and right sides of the mounting frame; a second motor is also installed in the mounting frame, a rotating shaft is fixed to the output shaft of the second motor, and a cam is fixed to the surface of the rotating shaft; a first spring is installed below the mounting frame, a pressure plate is fixed to the bottom of the first spring, a second spring is fixed to the bottom of the pressure plate, and a drain plate is fixed to the bottom of the second spring; the cam is located above the pressure plate, and realizes the up and down reciprocating motion of the pressure plate by pushing the pressure plate;

[0010] A connecting frame is fixed to the rear side of the pressing plate. The connecting frame extends downward and a lifting plate is connected to the bottom of the connecting frame. The lifting plate is located between two layers of belts.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model arranges the drain mechanism so that the washed eels can be drained, and the washed eels are placed on the surface of the belt. When the first motor is started, the belt is driven to rotate through the transmission roller, so that the eels can be transported, and the second motor is driven to rotate the cam through the rotating shaft when it is started. When the cam rotates downward, the cam surface pushes the pressure plate downward, so that the first spring is stretched and the drain plate can collide with the surface of the eel being transported. The collision of the drain plate is equivalent to a physical extrusion effect, which can force water to be squeezed out from the surface of the eel, and the second spring can generate compression, so that the drain plate can be buffered. Compared with direct and strong mechanical extrusion, this gentle pressing effect can reduce Less physical damage to the surface of the eel is beneficial to maintaining the integrity of the eel's appearance and reducing quality loss. The movement of the pressure plate will drive the lifting plate to move synchronously through the connecting frame. When the cam rotates upward, the first spring will reset, causing the pressure plate to drive the lifting plate to move upward through the connecting frame. At this time, the lifting rod on the surface of the lifting plate will slightly lift the belt, causing the belt surface to vibrate. The vibration can make the gap between the eel and the belt constantly change, which helps to form more tiny gaps, providing more escape paths for moisture and accelerating the drainage process. The fan can be in working condition, and the wind can take away the evaporated moisture, while promoting air circulation on the surface of the eel, making the moisture evaporation more uniform and efficient.

DETAILED DESCRIPTION

[0020] like Figure 1-6 As shown, an eel freezing and packaging integrated machine comprises a draining mechanism 2, a freezing mechanism 3 and a packaging machine 1 which are arranged in sequence from left to right;

[0021] The packaging machine 1 is used for packaging frozen eels, the draining mechanism 2 allows the washed eels to be drained, and the freezing mechanism 3 allows the eels to be frozen.

[0022] The drain mechanism 2 includes a support platform 201, on which a plurality of transmission rollers 203 are provided to rotate from left to right, and on which a belt 204 is provided. The transmission rollers 203 are driven by a first motor 202 provided on the support platform 201 to drive the belt 204;

[0023] A mounting frame 205 is fixed above the middle of the support platform 201, and a fan 206 is provided on each of the left and right sides of the mounting frame 205; a second motor 207 is also installed in the mounting frame 205, and a rotating shaft 208 is fixed to the output shaft of the second motor 207, and a cam 209 is fixed to the surface of the rotating shaft 208; a first spring 210 is installed below the mounting frame 205, and a pressing plate 211 is fixed to the bottom of the first spring 210, and a second spring 212 is fixed to the bottom of the pressing plate 211, and a drain plate 213 is fixed to the bottom of the second spring 212; the cam 209 is located above the pressing plate 211, and realizes the reciprocating movement of the pressing plate 211 up and down by pushing the pressing plate 211;

[0024] A connecting frame 214 is fixed to the rear side of the pressing plate 211 . The connecting frame 214 extends downward and a lifting plate 215 is connected to the bottom of the connecting frame 214 . The lifting plate 215 is located between the two belts 204 .

[0025] The washed eels are placed on the surface of the belt 204. When the first motor 202 is started, the belt 204 is driven to rotate through the transmission roller 203 so that the eels can be transported. When the second motor 207 is started, the cam 209 is driven to rotate through the rotating shaft 208. When the cam 209 rotates downward, the surface of the cam 209 pushes the pressing plate 211 downward, so that the first spring 210 is stretched and the drain plate 213 can collide with the surface of the eel being transported. Since the collision of the drain plate 213 is equivalent to a physical squeezing effect, it can force water to squeeze out of the surface of the eel, and the second spring 212 can generate compression, so that the drain plate 213 can be buffered. Compared with direct and strong mechanical squeezing, this gentle pressing effect can reduce physical damage to the surface of the eel, which is conducive to maintaining the appearance integrity of the eel and reducing quality loss.

[0026] The movement of the pressure plate 211 will drive the lifting plate 215 to move synchronously through the connecting frame 214. When the cam 209 rotates upward, the first spring 210 is reset, so that the pressure plate 211 drives the lifting plate 215 to move upward through the connecting frame 214. At this time, the lifting rod on the surface of the lifting plate 215 will slightly lift the belt 204, causing the surface of the belt 204 to vibrate. The vibration can make the gap between the eel and the belt 204 constantly change, which helps to form more tiny gaps, providing more escape paths for moisture, and accelerating the drainage process. The fan 206 can be in working state, and the wind can take away the evaporated moisture, while promoting air circulation on the surface of the eel, making the moisture evaporation more uniform and efficient.

[0027] Furthermore, the freezing mechanism 3 includes a roller conveyor 301, and the left and right ends of the roller conveyor 301 are respectively connected to the draining mechanism 2 and the packaging machine 1; a freezing chamber shell 302 is provided in the middle of the roller conveyor 301, a cooling pipe 303 is fixed to the inner wall of the freezing chamber shell 302, a nozzle 304 is connected to the surface of the cooling pipe 303, and the surface of the cooling pipe 303 passes through the freezing chamber shell 302 and is connected to a connecting valve 305.

[0028] The roller conveyor 301 can convey the drained eels, and the connecting valve 305 can be connected to the external liquid nitrogen conveying equipment. When the eels are conveyed to the inside of the freezing chamber shell 302, the connecting valve 305 is opened to allow the liquid nitrogen to be sprayed out through the cooling pipe 303 and the nozzle 304, and the liquid nitrogen can quickly freeze the eels. The frozen eels can be directly conveyed to the inside of the packaging machine 1 for packaging through the roller conveyor 301.

[0029] The bottom of the freezing chamber shell 302 is connected to a drain valve 306 , and the entrances and exits on the left and right sides of the freezing chamber shell 302 are both fixed with sealing curtains 307 .

[0030] The V-shaped structure can make the liquid nitrogen gather at the lowest point at the bottom of the freezing chamber shell 302, so that the liquid nitrogen can be more easily discharged through the drain valve 306, and the closed curtain 307 can provide a certain protection effect on the cold air and liquid nitrogen, so that the liquid nitrogen is not easy to splash outside the freezing chamber shell 302.

[0031] The surfaces of the mounting frame 205 and the pressure plate 211 are penetrated by a sliding rod 217 , the bottom of the sliding rod 217 is fixedly connected to the top of the drain plate 213 , and the first spring 210 and the second spring 212 are sleeved on the outer periphery of the sliding rod 217 .

[0032] The slide bar 217 can provide a guiding effect for the pressing plate 211 and the drain plate 213 to prevent the pressing plate 211 and the drain plate 213 from being offset when the first spring 210 and the second spring 212 are compressed.

[0033] The first spring 210 is a tension spring, and the second spring 212 is a compression spring.

[0034] By selecting the corresponding springs, it is ensured that when the cam 209 rotates upward, the first spring 210 can pull the pressure plate 211 to move upward, and when the drain plate 213 contacts the surface of the eel, the second spring 212 can be compressed inward and reset.

[0035] The surface of the support platform 201 is rotatably connected to a plurality of support rollers 216 , and the support rollers 216 are slidably connected to the surface of the belt 204 .

[0036] The support roller 216 can provide support for the belt 204 to prevent the belt 204 from being greatly depressed downward due to gravity when the eels are transported to a position near the middle of the belt 204 .

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
