Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging equipment, specifically to a dividing turntable assembly of a large bag-feeding packaging machine. Background Art
[0002] The structure of a general bag-feeding packaging machine includes a dividing turntable, on which are installed bag clamping assemblies evenly distributed around the circumference. The bag clamping assemblies sequentially pass through the bag loading station, bag opening station, feeding station, transfer station, and finally transfer to the vacuum sealing station. When such a bag-feeding packaging machine is used for packaging bags weighing more than 5 kilograms and with large bag specifications, the bag clamping assemblies may not be able to clamp the bags sufficiently or the bags may be stretched, deformed, or even torn by gravity. At the same time, the movement of the transferred bags is unstable due to their heavy weight, thus affecting the packaging quality and efficiency. Utility Model Content
[0003] To solve the above problems, the utility model provides a dividing turntable assembly for a large bag-feeding packaging machine, which aims to ensure stable transfer when the packaging bag is loaded with materials weighing more than 5 kilograms and avoid deformation of the packaging bag.
[0004] To achieve the above-mentioned purpose, the utility model provides a dividing turntable assembly of a large bag-feeding packaging machine, comprising a frame, a dividing turntable and a bag clamping assembly evenly distributed around the circumference, wherein a load-bearing support plate that can be adjusted up and down is provided under the bag clamping assembly; the load-bearing support plate is connected to the dividing turntable through a bracket, a vertical guide rod is provided on the bracket, an adjustment seat is slidably installed on the vertical guide rod, the load-bearing support plate is fixed to the adjustment seat and the height is locked by a tightening screw.
[0005] The indexing turntable assembly includes the following core improvements:
[0006] 1. Load-bearing support plate adjustment mechanism: An L-shaped bracket 5 is provided below each bag clamping assembly 3, connected to a slidable adjustment seat 52 via a vertical guide rod 51; a load-bearing support plate 4 is fixed to the adjustment seat 52, and its height is locked by a tension screw. The adjustment range covers 30-200mm, adapting to different bag shapes;
[0007] 2. The surface of the load-bearing plate 4 is processed with anti-slip patterns or paved with anti-slip mats, with a friction coefficient of ≥0.5 to prevent the bag from sliding.
[0008] 3. Guide rail structure: An arc-shaped guide rail 6 is installed on the inner side of the frame 1, and the arc radius is consistent with the rotation trajectory of the indexing turntable 2; the gap between the arc-shaped guide rail 6 and the inner side of the adjustment seat 52 is ≤ 2mm, which limits the radial swing amplitude of the load-bearing support plate. At the same time, the bearing 53 can further share the load-bearing support plate 4 by rolling along the arc-shaped guide rail 6, and also reduce the load-bearing force of the indexing turntable 2, making its rotation smoother. Beneficial effects
[0009] Improved stability: The load-bearing plate distributes more than 90% of the bag's weight, and the bag clamping component only needs to provide 10%-15% auxiliary clamping force to prevent bag opening deformation.
[0010] Compatibility Optimization: The height adjustment seat can adapt to a variety of bag types (such as square feed bags and cylindrical rice bags), reducing the time required for a single adjustment;
[0011] Reduced failure rate: The guide rail design reduces the swing amplitude of the packaging bag and improves the success rate of vacuum chamber transfer.
[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.
[0017] like Figure 1 、 Figure 2 As shown, this embodiment discloses a dividing turntable assembly of a large bag-feeding packaging machine, including a frame 1, a dividing turntable 2 and a bag clamping assembly 3 evenly distributed around the circumference, and a load-bearing support plate 4 that can be adjusted up and down is provided below the left and right clamps of the bag clamping assembly 3; the surface of the load-bearing support plate 4 is provided with anti-slip grooves (not shown in the figure) or an anti-slip mat (not shown in the figure) to prevent the packaging bag from sliding; the load-bearing support plate 4 is connected to the dividing turntable 2 through a bracket 5, and two vertical guide rods 51 are provided on the bracket 5, and an adjustment seat 52 is slidably installed on the vertical guide rod 51, and the load-bearing support plate 4 is fixed to the adjustment seat 52 and the height is locked by a loosening screw.
[0018] An adjustable curved guide rail 6 is mounted on the frame 1. Its outer surface is loosely fitted with the end of the adjustment seat 52 facing the center of the turntable. The curvature of the curved guide rail 6 matches the rotational trajectory of the indexing turntable 2. A bearing 53 is mounted on the adjustment seat 52, and the bearing 53 rolls in contact with the curved guide rail 6. This allows the weight of the load-bearing support plate 4 to be transferred to the frame 1 via the bearing 53 and the curved guide rail 6.
[0019] A vertically arranged guide column 7 is installed on the frame 1, and a guide rail fixing seat 8 is slidably installed on the guide column 7. The arc guide rail 6 is fixed on the guide rail fixing seat 8. The guide rail fixing seat 8 is locked in height by adjusting the screw. The height of the guide rail fixing seat 8 is adjusted according to the position of the adjustment seat 52 to ensure that the bearing 53 is in contact with the arc guide rail 6.
[0020] The bracket 5 is an L-shaped metal component. The indexing turntable 2 is provided with a mounting groove that matches the horizontal section of the bracket 5. The horizontal section of the bracket 5 is placed in the mounting groove and connected by bolts.
[0021] The beneficial effects achieved by adopting the above embodiment are:
[0022] Improved stability: The load-bearing plate distributes more than 90% of the bag's weight, and the bag clamping component only needs to provide 10%-15% auxiliary clamping force to prevent bag mouth deformation;
[0023] Compatibility Optimization: The height adjustment seat can adapt to a variety of bag types (such as square feed bags and cylindrical rice bags), reducing the time required for a single adjustment;
[0024] Reduced failure rate: The guide rail design reduces the swing amplitude of the packaging bag and improves the success rate of vacuum chamber transfer.
