[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the design of an infrared sensor, a first motor, a load cell, a conveyor belt, and a filling and loosening mechanism, when packaging fish feed, the packaging container is placed on the surface of the conveyor belt, and the first motor is started to drive the transmission column to drive two sets of conveyor belts. This allows the conveyor belt to transport the packaging container until it is level with the infrared sensor. At this point, the infrared sensor sends a signal to the controller, causing the controller to stop the first motor and start the filling and loosening mechanism and the second electric push rod. Simultaneously, the packaging container, being level with the infrared sensor, is also positioned on the upper surface of the load cell. The activation of the second electric push rod pushes the load cell up from within the conveyor belt, causing the load cell to push the packaging container between the conveyor belts, placing the packaging container on the upper surface of the load cell, thus enabling the weighing transmission... The sensor monitors the weight of the packaging container in real time. Once the fish feed poured into the container by the filling and loosening mechanism reaches the set weight value, the weighing sensor sends a signal to the controller. This causes the controller to restart the first motor, shut down the filling and loosening mechanism, and restart the second electric push rod. The second electric push rod pulls the weighing sensor back, allowing the packaging container on the surface of the weighing sensor to be placed on the surface of the conveyor belt. The conveyor belt then transports the packaging container with the specified weight. Through the coordinated work of the infrared sensor, the weighing sensor, and the controller, the entire packaging process is highly automated. When the packaging container reaches the correct position, the infrared sensor sends a signal, triggering subsequent operations such as unloading and weighing. The close connection between each link improves production efficiency and reduces the time and workload of manual intervention.

[0017] 2. Through the design of the second motor, spiral loosening rod, storage box, closing lid, and first electric push rod, the conveyor belt transports the packaging container to a position flush with the infrared sensor. The infrared sensor then sends a signal to the controller, causing the controller to stop the first motor and activate the first and second electric push rods. The first electric push rod pulls the connecting plate at one end of the closing lid, allowing the lid to unfold from the lower end of the storage box's outlet. This allows the fish feed stored in the storage box to be poured into the packaging container. The second electric push rod then pushes the weighing sensor up from within the conveyor belt, positioning the packaging container above the weighing sensor. This allows the weighing sensor to monitor the weight of the packaging container in real time until the amount of fish feed poured into the container reaches the specified level. Once the set weight value is reached, the weighing sensor sends a signal to the controller, which then restarts the first motor and activates the first and second electric push rods. The first electric push rod pushes the closing cover at one end of the piston rod to seal the outlet of the storage box, while the second electric push rod pulls the weighing sensor down, allowing the packaging container on the upper surface of the weighing sensor to be placed on the surface of the conveyor belt. The conveyor belt then transports the packaging container containing the specific weight away. When the fish feed in the storage box is poured into the packaging container, the second motor is activated simultaneously, driving the spiral loosening rod to rotate inside the storage box to stir and loosen the fish feed, thereby preventing the fish feed from clumping inside the storage box and allowing the various components in the fish feed to be mixed more evenly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This embodiment provides the following technical solution:

[0026] like Figures 1-3 As shown, a fish feed quantitative packaging device includes: a U-shaped frame 1, two sets of transmission columns 106 rotatably installed inside the U-shaped frame 1, a first motor 103 fixedly installed at one end of the U-shaped frame 1, the output shaft of the first motor 103 passing through the U-shaped frame 1 and fixedly connected to the transmission columns 106, conveyor belts 107 being fitted on both ends of the outer surfaces of the two sets of transmission columns 106, a support frame 101 fixedly installed on the upper surface of the U-shaped frame 1, a filling and loosening mechanism 2 fixedly installed inside the support frame 101, fish feed being stored inside the filling and loosening mechanism 2, and the filling and loosening mechanism 2 being able to break up the fish feed stored inside during the process of pouring it out.

[0027] Support plates 104 are fixedly installed on both sides of the inner side of the U-shaped frame 1. The support plates 104 are located on both sides of the inner side of the conveyor belt 107. A weighing sensor 105 is arranged between the two sets of support plates 104. The weighing sensor 105 is fixedly installed on the upper surface of the piston rod of the second electric push rod 108. The second electric push rod 108 is fixedly installed between the U-shaped frames 1. The weighing sensor 105 is located between the two sets of conveyor belts 107. The upper surface of the weighing sensor 105 can be pushed higher than the upper surface of the conveyor belt 107 by the piston rod of the second electric push rod 108.

[0028] An infrared sensor 102 is fixedly installed inside the support frame 101. The infrared sensor 102 is used to detect the packaging container delivered directly below it. When the packaging container is detected, it will be located on the surface of the weighing sensor 105 and be flush with the filling and loosening mechanism 2, thereby allowing the filling and loosening mechanism 2 to pour fish feed into the packaging container. At the same time, the weighing sensor 105 monitors the weight of the packaging container in real time.

[0029] The signal transmitting ends of the infrared sensor 102 and the weighing sensor 105 are both connected to the signal receiving end of the controller. The control output end of the controller is electrically connected to the electrical control end of the first motor 103 and the second electric push rod 108. The models of the infrared sensor 102, the weighing sensor 105 and the controller are Omron E3Z, HBM PW25 and Omron E3X-DA-S, respectively.

[0030] Through the design of the infrared sensor 102, the first motor 103, the weighing sensor 105, the conveyor belt 107, and the filling and loosening mechanism 2, when packaging fish feed, the packaging container is placed on the surface of the conveyor belt 107, and the first motor 103 is started to drive the transmission column 106 to drive the two sets of conveyor belts 107. This allows the conveyor belts 107 to transport the packaging container until it is flush with the infrared sensor 102. At this point, the infrared sensor 102 sends a signal to the controller, causing the controller to stop the first motor 103 and start the filling and loosening mechanism 2 and the second electric push rod 108. Simultaneously, the packaging container, being flush with the infrared sensor 102, is also positioned on the upper surface of the weighing sensor 105. The activation of the second electric push rod 108 pushes the weighing sensor 105 out of the conveyor belt 107, causing the weighing sensor 105 to push the packaging container between the conveyor belts 107, bringing the packaging container into position for weighing. On the upper surface of the device 105, the weighing sensor 105 monitors the weight of the packaging container in real time. When the fish feed poured into the packaging container by the filling and loosening mechanism 2 reaches the set weight value, the weighing sensor 105 sends a signal to the controller. This causes the controller to restart the first motor 103, shut down the filling and loosening mechanism 2, and restart the second electric push rod 108. The second electric push rod 108 pulls the weighing sensor 105 back, allowing the packaging container on the upper surface of the weighing sensor 105 to be placed on the surface of the conveyor belt 107. The conveyor belt 107 then transports the packaging container with the specified weight. Through the coordinated work between the infrared sensor 102, the weighing sensor 105, and the controller, the entire packaging process is highly automated. When the packaging container reaches the correct position, the infrared sensor 102 sends a signal to trigger subsequent operations, such as unloading and weighing. The close connection between each link improves production efficiency and reduces the time and workload of manual intervention.

[0031] like Figures 4-5 As shown, the filling and loosening mechanism 2 includes a storage box 203, which is fixedly installed inside the support frame 101. A closing cover 204 is rotatably installed on both sides of the discharge port opened on the lower surface of the storage box 203. A connecting plate 205 is fixedly installed at one end of the lower surface of the closing cover 204. The connecting plate 205 is rotatably connected to the piston rod of the first electric push rod 206. The first electric push rod 206 is rotatably installed inside the connecting frame 207. The connecting frame 207 is fixedly installed at one end of the storage box 203. The first electric push rod 206 is also controlled by the controller.

[0032] An inclined plate 208 is fixedly installed on the upper surface of the storage box 203. A second motor 201 is fixedly installed on one end of the inclined plate 208. A spiral loosening rod 202 is fixedly installed on one end of the output shaft of the second motor 201, so that the spiral loosening rod 202 rotates in the air inside the storage box 203.

[0033] Specifically, in this embodiment, in order to meet actual usage requirements, both the first motor 103 and the second motor 201 are geared motors.

[0034] Specifically, in this embodiment, in order to place the U-shaped frame 1 stably, several support legs are fixedly installed at the bottom of the U-shaped frame 1.

[0035] Through the design of the second motor 201, spiral loosening rod 202, storage box 203, closing cover 204, and first electric push rod 206, the conveyor belt 107 transports the packaging container to a position flush with the infrared sensor 102. The infrared sensor 102 then sends a signal to the controller, causing the controller to stop the first motor 103 and activate the first electric push rod 206 and the second electric push rod 108. The first electric push rod 206 then pulls the connecting plate 205 at one end of the closing cover 204, allowing the closing cover 204 to unfold from the lower end of the discharge port of the storage box 203. This allows the fish feed stored in the storage box 203 to be poured into the packaging container from the discharge port. The second electric push rod 108 then pushes the weighing sensor 105 up from within the conveyor belt 107, positioning the packaging container above the weighing sensor 105. This allows the weighing sensor 105 to monitor the weight of the packaging container in real time until the contents are poured into it. Once the fish feed reaches the set weight value, the weighing sensor 105 sends a signal to the controller, which then restarts the first motor 103 and activates the first electric push rod 206 and the second electric push rod 108. The first electric push rod 206 pushes the closing cover 204 at one end of the piston rod to seal the discharge port of the storage box 203, while the second electric push rod 108 pulls the weighing sensor 105 down, allowing the packaging container on the upper surface of the weighing sensor 105 to be placed on the surface of the conveyor belt 107. The conveyor belt 107 then transports the packaging container containing the specific weight away. When the fish feed in the storage box 203 is poured into the packaging container, the second motor 201 is activated to drive the spiral loosening rod 202 to rotate inside the storage box 203, thereby stirring and loosening the fish feed inside the storage box 203. This prevents the fish feed from clumping inside the storage box 203 and allows the various components in the fish feed to be mixed more evenly.

[0036] Based on the above technical solution, the working steps of this solution are summarized as follows: When packaging fish feed, the packaging container can be placed on the surface of the conveyor belt 107, and the first motor 103 can be started to drive the transmission column 106 to drive the two sets of conveyor belts 107. This allows the conveyor belts 107 to transport the packaging container until it is level with the infrared sensor 102. Then, the infrared sensor 102 sends a signal to the controller, causing the controller to stop the drive of the first motor 103 and start the first electric push rod 206 and the second electric push rod 108. The first electric push rod 206 pulls the connecting plate 205 at one end of the closing cover 204, thereby opening the closing cover 204 from the lower end of the discharge port of the storage box 203. This allows the fish feed stored in the storage box 203 to be poured into the packaging container from the discharge port. The second electric push rod 108 pushes the weighing sensor 105 up from inside the conveyor belt 107, allowing the packaging container to be fully opened. The container is positioned on the upper surface of the weighing sensor 105, allowing the weighing sensor 105 to monitor the weight of the packaging container in real time. Once the fish feed poured into the packaging container reaches the set weight value, the weighing sensor 105 sends a signal to the controller, which then enables the controller to restart the first motor 103 and activate the first electric push rod 206 and the second electric push rod 108. The first electric push rod 206 pushes the closing cover 204 at one end of the piston rod to seal the discharge port of the storage box 203, while the second electric push rod 108 pulls the weighing sensor 105 down, allowing the packaging container on the upper surface of the weighing sensor 105 to be placed on the surface of the conveyor belt 107. The conveyor belt 107 then transports the packaging container containing the specific weight away. When the fish feed in the storage box 203 is poured into the packaging container, the second motor 201 is activated simultaneously, driving the spiral loosening rod 202 to rotate inside the storage box 203, thereby stirring and loosening the fish feed inside the storage box 203.

[0037] In summary, the process of pouring fish feed can loosen the fish feed in storage box 203, thereby preventing the fish feed from clumping in storage box 203 and allowing the various components of the fish feed to be mixed more evenly.

[0038] All parts not described in this utility model are the same as or can be implemented using existing technology.
