Description

Technical Field

[0001] This utility model relates to the technical field of shrimp vacuum packaging machines, specifically a synchronous quantitative weighing vacuum packaging machine for shrimp. Background Technology

[0002] A vacuum packaging machine for seasoned shrimp is a device used to vacuum-pack seasoned shrimp. Its main function is to pack shrimp into bags and remove air from the bags through vacuuming, thereby extending the shrimp's shelf life and preserving its freshness.

[0003] A search revealed existing technology, such as CN215044017U, a shrimp vacuum packaging device, including a processing table and a support column. A conveyor belt is movably mounted on the top of the processing table, and a top extraction frame is fixedly installed on the top of the support column. A hydraulic tank is fixedly installed in the middle of the inner cavity of the top extraction frame, and a hydraulic device is fixedly installed on the top of the inner cavity of the hydraulic tank. A stretching suction plate is fixedly connected to the bottom of the hydraulic device, and a suction column is fixedly connected to the bottom of the stretching suction plate. This invention, by setting up a vacuum extraction device, addresses the issue that shrimp stored in the packaging bag will have low quality due to the lack of air extraction. The shrimp will be easily corroded and contaminated by the air, rendering them inedible. The vacuum extraction device removes the air from the packaging bag during the shrimp packaging process, thus avoiding both low shrimp quality and high cost, thereby improving the quality of shrimp packaging.

[0004] In summary, existing shrimp vacuum packaging devices have solved the problem of high cost losses. However, existing shrimp vacuum packaging devices usually rely on manual weighing of shrimp, which is inefficient and difficult to guarantee in terms of accuracy. Therefore, a synchronous quantitative weighing modulated shrimp vacuum packaging machine is proposed. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a vacuum packaging machine for shrimp meat with synchronous quantitative weighing. A conveying mechanism 2 is provided above the mounting platform 1, and several sets of placement slots 201 are installed on the conveying mechanism 2. A fixing frame 3 is installed above the mounting platform 1, and the fixing frame 3 is connected to the shrimp meat storage box 301.

[0025] To further explain, the top of the mounting platform 1 is equipped with a vacuum mechanism 4 that works in conjunction with the conveying mechanism 2. The vacuum mechanism 4 is existing technology and will not be described in detail.

[0026] Specifically, the shrimp storage box 301 has a first discharge port 302 at its bottom, which is connected to the quantitative storage box 303. The quantitative storage box 303 has a second discharge port 304 at its bottom, which is connected to the telescopic pipe 305 via a connector. The other end of the telescopic pipe 305 is connected to the discharge port 306, which is located directly above the weighing opening trough 307. A discharge channel 308 is provided on one side of the weighing opening trough 307, and a collection trough 309 is provided at the top of the discharge channel 308. The collection trough 309 facilitates the collection of materials.

[0027] In a further embodiment, the shrimp storage box 301 is provided with a feed inlet 3011 at the top, and the shrimp storage box 301 is provided with symmetrical inclined plates 3012 at the bottom of the inner side. The inclined plates 3012 facilitate the collection of materials above the first discharge port 302.

[0028] In a further embodiment, the first discharge port 302 and the second discharge port 304 are equipped with matching valves to facilitate the opening and closing of the first discharge port 302 and the second discharge port 304 in the future.

[0029] Specifically, drive plates 3061 are fixedly installed on both sides of the discharge port 306, and second electric telescopic rods 3062 are symmetrically arranged at the bottom of the quantitative storage box 303 to drive the drive plates 3061 to move. When the discharge port 306 is discharging, the second electric telescopic rod 3062 drives the telescopic tube 305 to be in an extended state, so that the discharge port 306 is closer to the weighing opening sump 307, avoiding the leakage of shrimp. When the discharge port 306 is not discharging, the second electric telescopic rod 3062 drives the telescopic tube 305 to be in a compressed state, so as to avoid the discharge port 306 affecting the weighing opening sump 307.

[0030] Specifically, the weighing opening trough 307 includes a weighing scale 3071, which can be electrically connected to a controller. When the weighing scale 3071 detects an abnormal weight of shrimp inside the opening trough 3075, it sends a signal to the controller, which then controls an alarm to sound. The weighing scale 3071 is installed above a horizontal plate 3072. A connecting plate 3073 is provided on the top of the weighing scale 3071, and two sets of vertical plates 3074 are provided on the top of the connecting plate 3073. The vertical plates 3074 are rotatably connected to the opening trough 3075, and the bottom of the opening trough 3075 is connected to the connecting plate 3073 via a first electric telescopic rod 3076. A third discharge port 3077 is provided on one side of the opening trough 3075, and a matching valve is installed inside the third discharge port 3077.

[0031] To further clarify, the first electric telescopic rod 3076 is movably connected to the connecting plate 3073 and the opening slot 3075.

[0032] In use, the valve inside the first discharge port 302 is opened to allow the shrimp in the shrimp storage box 301 to enter the quantitative storage box 303. After the shrimp completely fills the quantitative storage box 303, the valve inside the first discharge port 302 is closed, and the valve inside the second discharge port 304 is opened to allow the shrimp to enter the opening slot 3075 for weighing. After the weighing is correct, the first electric telescopic rod 3076 is opened. Under the action of the first electric telescopic rod 3076, the opening slot 3075 is tilted, so that the shrimp in the opening slot 3075 enters the discharge channel 308 through the third discharge port 3077, and finally enters the inside of the shrimp storage bag placed in the placement slot 201.
