Abstract
Description
Technical Field
[0001] This utility model relates to the field of bagging technology, specifically to an automatic bagging feeding hopper. Background Technology
[0002] In traditional material packaging processes, manual bagging is not only inefficient but also labor-intensive, especially when handling powdery or granular materials, easily leading to dust and spillage, affecting the working environment and the health of operators. While existing automated bagging equipment has improved efficiency to some extent, it still has shortcomings in securing the bag opening and controlling material feeding. For example, some equipment relies on complex mechanical structures or pneumatic devices to secure the bag opening, resulting in high costs and inconvenient maintenance; others lack effective sealing mechanisms, easily leading to material leakage or bag opening detachment during feeding, affecting the accuracy and stability of bagging. Therefore, there is an urgent need for a simple, easy-to-operate, and highly efficient automated bagging feeding hopper to solve the problems existing in current technologies. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing an automatic bagging feeding hopper.
[0004] This utility model is achieved through the following technical solution: providing an automatic bagging feeding hopper, including a hopper body with a discharge port at the lower end, with feeding plates hinged to both the front and rear sides of the lower end of the hopper body, the lower ends of the two feeding plates being fitted together to block the discharge port, and the lower ends of the two feeding plates being separated to open the discharge port, a limiting stop bar fixed to the hopper body is provided on the side of the two feeding plates that are far apart from each other, and an opening cylinder for driving the feeding plates to swing is installed on the hopper body.
[0005] In this solution, the bag opening is placed over the lower end of the two closed feeding plates. The opening cylinder drives the two feeding plates to open, and presses the two sides of the bag opening onto the two limit bars to fix the position of the bag opening. After the feeding plates open, the material in the hopper falls into the bag. After the bag is filled, the two feeding plates close to seal the outlet, and the bag containing the material falls.
[0006] As an optimization, the upper end of the feeding plate is hinged to the hopper body, and the two feeding plates are fitted together to form a cone shape. In this design, the feeding plates are fitted together to form a cone shape, which facilitates the packaging bag being placed on the structure after the two feeding plates are closed.
[0007] As an optimization, a bag-supporting mechanism is also included. This mechanism comprises a vertically lifting seat plate, two bag-supporting sliding seats slidably connected to the lifting seat plate, and a bag-supporting drive mechanism that drives the two sliding seats to slide in opposite directions. A bag-supporting arm is fixedly connected to each sliding seat, and a vertical bag-supporting rod is fixedly connected to each arm. The two bag-supporting rods are located on the left and right sides of the hopper body, respectively. In this design, the two bag-supporting rods are inserted into the bag opening when the packaging bag is inserted. By moving the two rods outward, they open both ends of the bag opening, straightening the opening of the material-filled packaging bag for easier subsequent conveying.
[0008] As an optimization, the bag-supporting drive mechanism includes two bag-supporting cylinders mounted on the lifting seat plate, and the telescopic shafts of the two bag-supporting cylinders are respectively connected to two bag-supporting sliding seats. In this solution, the two bag-supporting cylinders drive the two bag-supporting sliding seats to achieve sliding.
[0009] As an optimization, the lifting seat plate is vertically slidably connected to two lifting guide shafts. In this design, the vertical sliding of the lifting seat plate is guided by two lifting guide shafts.
[0010] As an optimization, the bag-supporting mechanism also includes a lifting seat cylinder that drives the lifting seat plate to move vertically up and down. In this solution, the lifting seat cylinder drives the lifting seat plate to move vertically up and down.
[0011] The beneficial effects of this utility model are as follows: The automatic bagging feeding hopper of this utility model, through the cooperation of a closed feeding plate and an opening cylinder, achieves rapid fixing and reliable clamping of the bag opening, ensuring that the bag opening remains open throughout the bagging process and preventing material spillage. The feeding plate design not only precisely controls the material flow but also automatically closes after bagging, effectively sealing the outlet and preventing residual material leakage. Simultaneously, the limit stop further enhances the stability of the bag opening fixation, making it particularly suitable for packaging bags of different sizes. The entire bagging process requires no manual intervention, significantly improving bagging efficiency, reducing labor intensity, and minimizing material waste and environmental pollution. It is especially suitable for the automated packaging needs of powdery and granular materials. The device has a simple structure, is easy to maintain, and possesses high practicality and economic efficiency. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0022] like Figures 1-7 As shown, the present invention provides an automatic bagging feeding hopper, which includes a hopper body 1 with a discharge port at the lower end, the hopper body 1 containing materials, and a feeding port at the upper end of the hopper body 1 for easy replenishment of materials.
[0023] The material hopper 1 has a feeding plate 2 hinged to both the front and rear sides at the lower end. The upper end of the feeding plate 2 is hinged to the material hopper 1 and the two hinge axes are set in parallel. The two feeding plates 2 are fitted together to form a cone shape, which makes it easy to put the bag mouth on.
[0024] The hopper body 1 is equipped with an opening cylinder 4 that drives the feeding plate 2 to swing. The upper end of the opening cylinder 4 is hinged to the bracket on the outside of the hopper body 1, and the lower end of the opening cylinder 4 is hinged to the feeding plate 2, thereby realizing the swinging of the feeding plate 2.
[0025] On the side of the two feeding plates 2 that are far apart from each other, there is a limiting rod 3 that is fixedly connected to the hopper body 1. The two limiting rods 3 are arranged in parallel, and the two ends of the limiting rods 3 are fixedly connected to the side plates 5 on the left and right sides of the hopper body 1, so as to achieve fixed connection with the hopper body 1 through the side plates 5.
[0026] The two feed plates 2 move in opposite directions until they are pressed against the limit stop bar 3 and then stop, thus pressing the packaging bag between the feed plate 2 and the limit stop bar 3.
[0027] The left and right side plates 5 of the hopper body 1 are provided with conical parts, and the packaging bag mouth is also wrapped around the conical parts when it is put on the lower end of the two lower plates 2.
[0028] The two feeding plates 2 separate at their lower ends to open the discharge port. At this time, the two feeding plates 2 open the bag opening and press the edge against the limit stop bar 3, and the material falls into the packaging bag.
[0029] To facilitate the subsequent conveying and sealing operations, the packaging bag opening is made elongated and flat. This application also includes a bag-supporting mechanism, which comprises a vertically lifting base plate 6, two bag-supporting sliding seats 8 slidably connected to the lifting base plate 6, and a bag-supporting drive mechanism that drives the two bag-supporting sliding seats 8 to slide in opposite directions.
[0030] The lifting seat plate 6 is located in front of or behind the hopper body 1. The lifting seat plate 6 is vertically slidably connected to two vertical lifting guide shafts 7, which are fixed to the frame. The bag-supporting mechanism also includes a lifting seat cylinder 13 that drives the lifting seat plate 6 to move vertically. The upper end of the lifting seat cylinder 13 is hinged to the frame, and the lower end is hinged to the lifting seat plate 6, thereby realizing the lifting operation of the lifting seat plate 6.
[0031] Four box-type linear bearings are fixedly connected to the bag support sliding seat 8, and two transverse sliding seat guide shafts 9 are fixedly connected to the lifting seat plate 6. The four box-type linear bearings slide on the two sliding seat guide shafts 9 respectively, thereby realizing the transverse sliding of the bag support sliding seat 8.
[0032] The bag-supporting drive mechanism includes two bag-supporting cylinders 10 mounted on the lifting seat plate 6. The two bag-supporting cylinders 10 extend in opposite directions. The cylinder body of the bag-supporting cylinder 10 is hinged to the lifting seat plate 6. The extension shafts of the two bag-supporting cylinders 10 are respectively connected to two bag-supporting sliding seats 8, thereby realizing the opposite sliding of the two bag-supporting sliding seats 8.
[0033] The bag-supporting sliding seat 8 is fixedly connected to two bag-supporting arms 11, which are arranged horizontally and parallelly, with their ends extending to the left and right sides of the hopper body 1. Vertical bag-supporting rods 12 are fixedly connected to the bag-supporting arms 11, with the two rods 12 located on the left and right sides of the hopper body 1, respectively. The bag-supporting rods 12 are vertical round shafts. When the packaging bag is placed under the hopper body 1, the two rods 12 are positioned close to the hopper body 1.
[0034] How to use this utility model:
[0035] In use, the bag opening is placed over the lower end of the two closed feeding plates 2. The opening cylinder 4 drives the two feeding plates 2 to open, and presses the two sides of the bag openings onto the two limit bars 3 respectively, thus fixing the position of the bag openings. After the feeding plates 2 open, the material in the hopper 1 falls into the bag. At the same time, the lifting seat cylinder 13 drives the lifting seat plate 6 to descend, so that the two bag-supporting rods 12 are inserted into the two ends of the bag opening. Then, the two bag-supporting sliding seats 8 move in the opposite direction, so that the two bag-supporting rods 12 open the two ends of the bag opening. After the bag is filled, the two feeding plates 2 close, thus sealing the outlet, and the bag containing the material falls.
