Description

Technical Field

[0001] This utility model relates to the field of mixed bean processing technology, and in particular to a quantitative screw feeding device for nitrogen-filled mixed bean processing. Background Technology

[0002] Nitrogen is commonly used in modern times to replace air in food storage and transportation, effectively reducing the possibility of food oxidation and spoilage and extending the shelf life of food. In the canning and packaging process of mixed beans, a certain amount of mixed beans needs to be injected into the can first, and then nitrogen is filled into the can to complete the packaging operation.

[0003] Before nitrogen filling, a variety of beans need to be evenly mixed and put into the tank to be filled with nitrogen. However, most current feeding devices are equipped with multiple spiral feeding structures to ensure the feeding of different beans. Each spiral structure operates independently, resulting in high operating costs, high energy consumption, increased maintenance costs and overall operating expenses.

[0004] Therefore, in view of the fact that existing nitrogen-filled mixed bean processing equipment requires multiple independent spiral feeding structures according to the variety of beans when feeding nitrogen, a quantitative spiral feeding device for nitrogen-filled mixed bean processing can be designed. By using segmented feeding, regardless of the variety of beans, only two sets of spiral structures are needed to complete the quantitative feeding operation, improve the linkage between device structures, reduce the power source of the device, reduce energy consumption and operating costs, and thus effectively enhance the practical value of the device. Utility Model Content

[0005] To overcome the problem that most nitrogen-filled mixed bean processing feeding devices are equipped with multiple spiral feeding structures to ensure the feeding of different types of beans, and each spiral structure operates independently, resulting in high operating costs and high energy consumption, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a quantitative screw feeding device for nitrogen-filled mixed beans processing, including a feeding pipe and a storage component. The storage component is equidistantly arranged at the top of the feeding pipe. It also includes a feeding component, a discharge pipe and a feeding auger. The feeding component is arranged inside the feeding pipe. The feeding component includes a drive shaft, a spiral blade and a partition. The drive shaft is rotatably connected to the inside of the feeding pipe. The spiral blade is arranged outside the drive shaft. Multiple sets of partitions are equidistantly arranged outside the drive shaft. The partitions divide the feeding pipe into multiple feeding chambers of equal length. Multiple sets of discharge pipes are equidistantly connected to the bottom of the feeding pipe. The top of the discharge pipe is connected to the front end of the feeding chamber. A feeding auger is arranged at the bottom of each discharge pipe.

[0007] Preferably, by setting up storage components to store various types of beans in categories, the feeding component drives the drive shaft to rotate, and the drive shaft drives the spiral blades to rotate. The feeding pipes are divided by partitions at equal intervals, so that each storage component has a corresponding independent feeding chamber. The rotation of the spiral blades transports the beans in the storage components to the corresponding feeding chambers in the feeding pipes. The number of rotations of the spiral blades controls the feeding amount of each type of bean. Different types of beans are transported to the discharge pipe through the spiral blades. All beans are uniformly discharged to the feeding auger through the discharge pipe. The feeding auger transports the mixed beans to the tank or box to be nitrogen-filled. This achieves quantitative feeding operation with only two sets of spiral structures, improves the linkage between the device structures, reduces the power source of the device, reduces energy consumption and operating costs, and enhances the practical value of the device.

[0008] Preferably, the feeding assembly also includes a first motor, with the first motor located at the rear end of the feeding pipe, and the output end of the first motor connected to the drive shaft.

[0009] Preferably, the feeding assembly also includes annular grooves and limiting rings. Multiple sets of annular grooves are equidistantly provided on the inner side of the feeding pipe, and limiting rings are provided on the outer edge of the partition. The limiting rings are fitted and rotated along the annular grooves.

[0010] Preferably, the storage assembly includes a storage hopper and a hopper cover. Multiple storage hoppers are equidistantly arranged at the top of the feed pipe. The bottom of the storage hopper is connected to the rear end of the feeding chamber. The top of the storage hopper is provided with a hopper cover to close the storage hopper.

[0011] Preferably, a feeding pipe is connected to the bottom of the discharge pipe, a feeding auger is rotatably connected to the inside of the feeding pipe, a second motor is provided at the rear end of the feeding pipe, the output end of the second motor is connected to the feeding auger drive mechanism, and a discharge pipe is provided at the bottom of the front end of the feeding pipe.

[0012] Preferably, the feed pipe and the delivery pipe are fixed above the corresponding workstation of the modified atmosphere packaging machine by a support frame.

[0013] The beneficial effects of this utility model are:

[0014] During feeding, various beans are stored separately, and the feeding pipes are divided at equal intervals by partitions, so that each type of bean has a corresponding independent feeding chamber. The drive shaft rotates, driving the spiral blades to rotate, and the spiral blades transport the beans to the corresponding feeding chambers in the feeding pipes. The number of rotations of the spiral blades controls the amount of each type of bean fed. Different types of beans are transported to the discharge pipe through the spiral blades, and all beans are uniformly discharged to the feeding auger through the discharge pipe. The feeding auger transports the mixed beans and delivers them to the tank or box to be nitrogen-filled. Thus, only two sets of spiral structures are needed to complete the quantitative feeding operation, reducing the power source of the device, reducing energy consumption and operating costs. This solves the problem that most nitrogen-filled mixed bean processing feeding devices are equipped with multiple spiral feeding structures to ensure the feeding of different types of beans. Each spiral structure operates independently, resulting in high operating costs and high energy consumption. This enhances the practical value of the device. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] Please see Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment: a quantitative screw feeding device for nitrogen-filled mixed beans processing, including a feeding pipe 1 and a storage component. The storage component is equidistantly arranged at the top of the feeding pipe 1. It also includes a feeding component, a discharge pipe 2 and a feeding auger 3. The feeding component is arranged inside the feeding pipe 1. The feeding component includes a drive shaft 101, a spiral blade 102 and a partition 103. The drive shaft 101 is rotatably connected to the inside of the feeding pipe 1. The spiral blade 102 is arranged outside the drive shaft 101. Multiple sets of partitions 103 are equidistantly arranged outside the drive shaft 101. The partitions 103 divide the feeding pipe 1 into multiple feeding chambers of equal length. Multiple sets of discharge pipes 2 are equidistantly connected to the bottom end of the feeding pipe 1. The top end of the discharge pipe 2 is connected to the front end of the feeding chamber. A feeding auger 3 is arranged at the bottom end of each discharge pipe 2.

[0023] Please see Figure 2 In this embodiment, the feeding assembly further includes a first motor 104. The first motor 104 is located at the rear end of the feeding pipe 1, and its output end is connected to the drive shaft 101. The first motor 104 is typically an SGM7G servo motor. The first motor 104 drives the drive shaft 101 to rotate, thereby driving the spiral blades 102 to rotate and feed material. The number of rotations of the spiral blades 102 can be flexibly controlled to achieve quantitative feeding. The storage assembly includes... Storage hopper 401 and hopper cover 402: Multiple sets of storage hoppers 401 are equidistantly arranged at the top of the feeding pipe 1. The bottom end of the storage hopper 401 is connected to the rear end of the feeding chamber. The top of the storage hopper 401 is provided with a hopper cover 402. The storage hopper 401 is closed by the hopper cover 402. Different types of beans are stored separately by the storage hopper 401 to ensure that the quantity of each type of bean in the mixed beans is evenly distributed. The storage hopper 401 is opened and closed flexibly by the hopper cover 402 to prevent impurities from falling into the storage hopper 401.

[0024] Please see Figure 3 and Figure 4 In this embodiment, the bottom end of the discharge pipe 2 is connected to the feeding pipe 301, and the feeding auger 3 is rotatably connected to the inside of the feeding pipe 301. A second motor 302 is provided at the rear end of the feeding pipe 301, and the output end of the second motor 302 is connected to the driving mechanism of the feeding auger 3. A discharge pipe 303 is provided at the bottom of the front end of the feeding pipe 301. The second motor 302 is generally a DC geared motor of model JGA25-370. The second motor 302 drives the feeding auger 3 to rotate, and the rotation of the feeding auger 3 causes the mixed beans in the discharge pipe 2 to fall into the feeding pipe 301 in sequence. The rotation of the feeding auger 3 transports the mixed beans in the feeding pipe 301 to the discharge pipe 303, and the mixed beans are discharged from the discharge pipe 303 to the tank or box at the corresponding station. The feeding pipe 1 and the feeding pipe 301 are fixed above the corresponding station of the modified atmosphere packaging machine by a support frame.

[0025] Before feeding, different types of beans are sorted and stored in the storage hopper 401, and then the hopper cover 402 is tightly closed.

[0026] During feeding, the first motor 104 drives the drive shaft 101 to rotate, and the rotation of the drive shaft 101 drives the spiral blades 102 to rotate a corresponding number of revolutions. The rotation of the spiral blades 102 causes the beans in the storage hopper 401 to fall into the feeding pipe 1. Each type of bean falls into the feeding chamber separated by the corresponding partition 103. Different types of beans are transported to the discharge pipe 2 by the rotation of the spiral blades 102. All beans are uniformly discharged to the feeding pipe 301 through the discharge pipe 2. At the same time, the second motor 302 drives the feeding auger 3 to rotate, and the rotating feeding auger 3 transports the mixed beans. Finally, the mixed beans are discharged through the discharge pipe 303 into the tank or box to be nitrogen-filled.

[0027] Example 2

[0028] Please see Figure 3 and Figure 4 The difference from Embodiment 1 is that in this embodiment, the feeding assembly further includes an annular groove 105 and a limiting ring 106. Multiple sets of annular grooves 105 are equidistantly provided on the inner side of the feeding pipe 1. A limiting ring 106 is provided on the outer edge of the partition 103. The limiting ring 106 is fitted and rotates along the annular groove 105. When the drive shaft 101 rotates, it drives the partition 103 to rotate synchronously. At this time, the limiting ring 106 rotates synchronously along the annular groove 105. The limiting ring 106 limits the partition 103, ensuring the stable rotation of the partition 103, and further ensuring the stable separation of the feeding pipe 1 by the partition 103.

[0029] Through the above steps, various beans are stored in a categorized manner using storage components. The feeding component drives the drive shaft 101 to rotate, which in turn drives the spiral blades 102 to rotate. The feeding pipes 1 are equidistantly separated by partitions 103, so that each storage component has an equidistant and independent feeding chamber. The spiral blades 102 rotate to transport the beans in the storage components to the corresponding feeding chambers in the feeding pipes 1. The number of rotations of the spiral blades 102 controls the amount of each type of bean fed. Different types of beans are transported to the discharge pipe 2 through the spiral blades 102. All beans are then uniformly discharged to the feeding auger 3 through the discharge pipe 2. The feeding auger 3 transports the mixed beans to the tank or box to be nitrogen-filled. Thus, only two sets of spiral structures are needed to complete the quantitative feeding operation, improving the linkage between the device structures, reducing the power source of the device, and lowering energy consumption and operating costs.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
