Description

Technical Field

[0001] This utility model relates to a bagging machine, specifically to a bag-supporting mechanism for a bagging machine. Background Technology

[0002] A bagging machine is a specialized piece of equipment used for the automated bagging of materials. The bag-opening mechanism is primarily used to open the bag opening to facilitate subsequent filling. Traditional bag-opening mechanisms mainly consist of two lateral opening plates that can swing. During operation, the bag is opened by controlling the swing of the opening plates. The drawback of this structure in practical use is that, because the opening plates only swing, they are linearly arranged when in a waiting state. To avoid interference between the two opening plates, their length is limited to a maximum of half the width of the bag opening. When opening smaller bags, the opening plates need to be replaced, which is cumbersome and results in a poor user experience. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a bag-supporting mechanism for a bagging machine to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A bag-supporting mechanism for a bagging machine, characterized in that: it includes left and right bag-supporting plates, the bag-supporting plates are mounted on corresponding swing blocks, the swing blocks are movably mounted on a movable seat and connected to a swing drive assembly, the movable seat is connected to the movable drive assembly, when the bag is being supported, the movable drive assembly first drives the movable seat to move, so that the two bag-supporting plates extend longitudinally into the open packaging bag, and then the swing drive assembly drives the swing blocks to swing, so that the bag-supporting plates swing outward to open the bag opening.

[0006] The swing drive assembly includes a drive shaft, the swing block is connected to the drive shaft, the drive shaft is rotatably mounted on the movable seat, the drive shaft is connected to one end of the transmission arm, and the other end of the transmission arm is hinged to the piston rod of the first cylinder.

[0007] The moving drive assembly includes a second cylinder, the piston rod of the second cylinder is connected to the moving seat, and a guide assembly is provided corresponding to the moving seat.

[0008] The bag-supporting mechanism of the bag-packing machine described above sets the bag-supporting plate on a movable seat, allowing the bag-supporting plate to first extend into the open packaging bag in a longitudinally parallel state. Then, the bag-supporting plate is controlled to swing and open the bag opening. This structure no longer limits the length of the bag-supporting plate, and the bag-supporting quality is stable and reliable. It can adapt to packaging bags of different sizes and effectively improves its versatility. Attached Figure Description

[0009] The present invention includes the following figures:

[0012] Figure 3 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] As shown in the figure, the bag-supporting mechanism of a bagging machine disclosed in this utility model includes bag-supporting plates 1 arranged on the left and right. The bag-supporting plates 1 are arranged on corresponding swing blocks 2. The swing blocks 2 are movably arranged on a movable seat 4 and connected to a swing drive assembly. The movable seat 4 is connected to the movable drive assembly. When the bag is supported, the movable drive assembly first drives the movable seat 4 to move, so that the two bag-supporting plates 1 extend longitudinally into the open packaging bag. Then, the swing drive assembly drives the swing blocks 2 to swing, so that the bag-supporting plates 1 swing outward to open the bag opening.

[0014] Furthermore, the swing drive assembly includes a drive shaft 3, with the swing block 2 connected to the drive shaft 3. The drive shaft 3 is rotatably mounted on the movable seat 4. One end of the drive shaft 3 is connected to the transmission arm 7, and the other end of the transmission arm 7 is hinged to the piston rod of the first cylinder 6. With this structure, by controlling the first cylinder 6 to drive the transmission arm 7, the drive shaft 3 can be rotated, thereby causing the swing block 2 and the bag support plate 1 to swing. Alternatively, a motor or similar structure can be used to directly drive the drive shaft 3 to rotate, thereby causing the swing block 2 and the bag support plate 1 to swing.

[0015] Furthermore, the moving drive assembly includes a second cylinder 5, the piston rod of which is connected to the moving seat 4, and a guide assembly is provided corresponding to the moving seat 4. The guide assembly includes a slide 9 connected to the moving seat 4, and a slide rail 8 that cooperates with the slide 9 is provided on the adjusting seat 10. With the above structure, the moving seat 4 and the bag support plate 1 can be moved by controlling the second cylinder 5.

[0016] Furthermore, two movable seats 4 are mounted on corresponding adjusting seats 10. The adjusting seats 10 are connected to a movable adjusting assembly, which can move the adjusting seats 10 to adjust the distance between the two adjusting seats 10. Specifically, the movable adjusting assembly includes an adjusting screw 11, which is rotatably mounted on the frame. The adjusting screw 11 has a first threaded section and a second threaded section with opposite thread directions. The first threaded section is screwed to one of the adjusting seats, and the second threaded section is screwed to the other adjusting seat. A guide assembly is provided for each adjusting seat. With the above structure, by controlling the rotation of the adjusting screw, the two adjusting seats 10 can be moved to adjust the distance between the two bag-supporting plates 1, adapting to packaging bags with different opening sizes and further improving the bag-supporting quality.

[0017] The working principle of this utility model is as follows: When the packaging bag is delivered to the filling station and the bag opening is opened, the second cylinder 5 is first controlled to drive the moving seat 4 to move, which in turn drives the two bag support plates 1 to extend longitudinally into the bag opening of the packaging bag. Then, the first cylinder 6 is controlled to move, which is transmitted through the transmission arm 7, thereby driving the drive shaft 3 to rotate, which in turn drives the swing block 2 and the bag support plates 1 to swing, so that the bag support plates 1 open the bag opening of the packaging bag.
