A high-efficiency feed bagging device

Abstract

This utility model relates to a high-efficiency feed bagging device, particularly in the field of feed processing equipment technology. The utility model includes a base plate, a first side plate, a second side plate, a buffer hopper, a weighing mechanism, a bagging bracket, a support frame, and a vibrating feeding mechanism. The weighing mechanism is located directly below the buffer hopper, and the bagging bracket is fixed to the base plate directly below the weighing mechanism. Through a two-stage control of coarse weighing and fine weighing, a large flow rate is initially used for feeding, followed by a small flow rate for compensation, resulting in an error rate of less than 1%, significantly improving weighing accuracy. When the coarse weighing stage is completed and the fine weighing stage is about to begin, the first solenoid valve closes. Due to the continuous operation of the vibrating motor, the buffer hopper continues to complete the pre-feeding work for the next coarse weighing without waiting, greatly saving bagging time and improving bagging efficiency to meet the needs of mass production.

The bagging process is time-consuming and cannot meet the needs of large-scale production. In addition, the vibration feeding of existing equipment can easily lead to uneven feed accumulation, affecting the stability of the bagging. Utility Model Content

The first side plate and the second side plate are vertically arranged on the top of the base plate. A fixing bracket for fixing the buffer hopper is provided between the first side plate and the second side plate. The weighing mechanism is located directly below the buffer hopper. The bagging bracket is fixed on the base plate directly below the weighing mechanism. The support frame is provided on the top of the base plate on one side of the first side plate. The vibrating feeding mechanism for feeding material into the buffer hopper is provided on the top of the support frame.

[0004] Preferably, the weighing mechanism includes a weighing hopper, a fixing plate, a weighing hopper placement plate, and a weighing sensor. A fixing plate is installed between the first side plate and the second side plate. The weighing hopper placement plate is provided between the fixing plates. The weighing sensor is provided on the weighing hopper placement plate. The weighing hopper is placed inside the weighing hopper placement plate.

[0007] Preferably, the area of ​​the first storage area is larger than the area of ​​the second storage area.

[0008] Preferably, the frame is equipped with a controller, and the first solenoid valve, the second solenoid valve, and the weighing sensor are electrically connected to the controller.

[0009] (2) Beneficial effects This invention provides a highly efficient feed bagging device, which has the following advantages compared with the prior art: 1. By using a two-stage control system of "coarse weighing + fine weighing" (first feeding at a large flow rate, then compensating with a small flow rate), the error rate is less than 1%, which greatly improves the weighing accuracy.

[0010] 2. When the coarse weighing stage is completed and the fine weighing stage is about to begin, the first solenoid valve closes. Due to the continuous operation of the vibrating motor, the buffer hopper continues to complete the pre-feeding work for the next coarse weighing without waiting, which greatly saves bagging time and improves bagging efficiency to meet the needs of mass production.

Detailed Implementation

[0017] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1-4 As shown, the present invention discloses a high-efficiency feed bagging device, comprising a base plate 1, a first side plate 2, a second side plate 3, a buffer hopper 5, a weighing mechanism, a bagging bracket 11, a support frame 12, and a vibrating feeding mechanism. The first side plate 2 and the second side plate 3 are vertically arranged on the top of the base plate 1. A fixing bracket 4 for fixing the buffer hopper 5 is provided between the first side plate 2 and the second side plate 3. The weighing mechanism is located directly below the buffer hopper 5. The bagging bracket 11 is fixed on the base plate 1 directly below the weighing mechanism for fixing feed bags. The support frame 12 is provided on the top of the base plate 1 on one side of the first side plate 2. The vibrating feeding mechanism for feeding material into the buffer hopper 5 is provided on the top of the support frame 12.

[0019] The weighing mechanism includes a weighing hopper 7, a fixing plate 8, a weighing hopper placement plate 9, and a weighing sensor 10. The fixing plate 8 is installed between the first side plate 2 and the second side plate 3. The weighing hopper placement plate 9 is located between the fixing plates 8. The weighing sensor 10 is located on the weighing hopper placement plate 9. The weighing hopper 7 is placed inside the weighing hopper placement plate 9. The bottom edge of the weighing hopper 7 is located on the weighing sensor 10. The material feeding is controlled by real-time monitoring of weight data.

[0020] The bottom of the buffer hopper 5 is provided with a first discharge port 51, and the bottom of the weighing hopper 7 is provided with a second discharge port 71. The first discharge port 51 is provided with a first solenoid valve 6, and the second discharge port 71 is provided with a second solenoid valve 72.

[0021] The vibrating feeding mechanism includes a frame 13, a vibrating box 14, a connecting plate 15, a shock-absorbing spring 16, and a vibrating motor 17. The frame 13 is fixed to the top of the support frame 12. The vibrating box 14 is located above the frame 13. The connecting plate 15 is located on both sides of the vibrating box 14. The upper end of the shock-absorbing spring 16 is fixedly connected to the connecting plate 15, and the lower end of the shock-absorbing spring 16 is fixedly supported on the support leg of the frame 13. The vibrating motor 17 is mounted on the bottom of the vibrating box 14 via a mounting base. The vibrating motor 17 drives the vibrating box 14 to vibrate at high frequency to prevent feed from bridging. The vibrating box 14 is divided into a first storage area 141 and a second storage area 142 by a partition 19. The first storage area 141 has a first discharge port 20 extending above the buffer hopper 5 on one side, and the second storage area 142 has a second discharge port 21 extending above the weighing hopper 7 corresponding to the buffer hopper 5 on one side.

[0022] The area of ​​the first storage area 141 is larger than the area of ​​the second storage area 142. A controller 18 is provided on the frame 13. The first solenoid valve 6, the second solenoid valve 72, and the weighing sensor 10 are electrically connected to the controller 18. The controller 18 receives the signal from the weighing sensor 10 and dynamically controls the opening and closing of each solenoid valve.

[0023] Working principle: Initial setup: Set the target weight (e.g., 50kg / bag) via the controller, start the vibration motor 17, and the feed will enter the two storage areas from the vibration box 14; Coarse weighing stage: When the fast feeding begins, the controller opens the first solenoid valve 6, and the buffer hopper 5 feeds material at a large flow rate into the weighing hopper 7. After feeding for a period of time, when the slow feeding stage begins, the vibration motor 17 is adjusted to reduce the vibration feeding frequency to make it close to the target value. When the weight reaches 90% of the target value, the first solenoid valve 6 is closed. Precision weighing stage: The feed is fed into the weighing hopper 7 in a small flow through the second feeding port 21 by low-frequency vibration of the vibration motor 17 until the weighing sensor 10 detects the precise weight. Feeding and bagging: The packaging bag is pre-placed inside the bagging bracket 11, the second solenoid valve 72 is opened, and the weighed feed in the weighing hopper 7 falls into the packaging bag, completing one bagging cycle. When the coarse weighing stage is completed and the fine weighing stage is about to begin, the first solenoid valve 6 is closed. Due to the continuous operation of the vibration motor 17, the buffer hopper 5 continues to complete the pre-feeding work for the next coarse weighing cycle without waiting, greatly saving bagging time and improving bagging efficiency.
