Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a material bag ejection mechanism for a valve bag packaging machine. Background Technology

[0002] A powder bag packaging machine is an automated device that integrates filling and bag sealing. After the material is injected into the packaging bag, it is first sealed and then pushed away to prepare for the next packaging.

[0003] Traditional pushing mechanisms mostly utilize hydraulic equipment, with a pusher plate installed at the output end of the hydraulic equipment. The hydraulic equipment extends, pushing the packaging bag away through the pusher plate, thereby achieving packaging separation.

[0004] However, with this method, the packaging bag is pushed and falls directly, making it easy for it to get caught on the packaging machine's parts, causing damage. The packaging bag may also tear upon landing due to the excessive weight of the materials it contains.

[0005] Therefore, this utility model provides a material bag ejection mechanism for a valve bag packaging machine, which enables the packaging bag to be ejected smoothly and avoids snagging. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing a material bag ejection mechanism for a valve bag packaging machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A material bag ejection mechanism for a valve bag packaging machine includes two drive rods rotatably mounted on both sides of the machine frame. A push frame is rotatably mounted on the upper ends of both drive rods. Driven rods, spaced apart from the drive rods, are rotatably mounted on both sides of the push frame. A connecting plate fixed to the machine frame is rotatably connected to the lower end of each driven rod. Ejection cylinders are rotatably mounted on both sides of the machine frame. The extended ends of the two ejection cylinders are rotatably connected to the corresponding drive rods. The drive rods and driven rods form a four-bar linkage, and their dimensions satisfy the following: the push frame remains vertical during deflection. A mounting plate is fixed to the lower end of the push frame on the side away from the machine frame. A support plate is rotatably mounted on the mounting plate. A tilting cylinder is rotatably mounted on the mounting plate below the support plate. A connecting rod is rotatably connected to the extended end of the tilting cylinder. The connecting rod is fixed to the support plate and rotatably mounted on one end of the push frame.

[0009] Preferably, the upper end of the pusher is provided with triangular support plates on both sides facing away from the frame. The upper end of the driven rod is rotatably mounted on the triangular support plate. An extension plate facing the frame is fastened to the side of the triangular support plate, and the upper end of the driving rod is rotatably mounted on the end of the extension plate.

[0010] Preferably, the driving rod and the driven rod are arranged alternately.

[0011] Preferably, a transverse cylinder is fixedly installed on each of the two triangular support plates, and the extended ends of the two transverse cylinders are arranged opposite to each other and are fixedly installed with clamps.

[0012] Preferably, the clamping plate is bent on the side facing the frame and a locking post is fixed at the other end.

[0013] Preferably, the mounting plate has a notch, and the extended end of the tilting cylinder passes through the notch and connects to the connecting rod.

[0014] Preferably, the side wall of the active rod is provided with a plurality of adjustment holes that are hinged to the extended end of the push-out cylinder.

[0015] Compared with the prior art, this utility model provides a material bag ejection mechanism for a valve bag packaging machine, which has the following beneficial effects:

[0016] First, the pusher cylinder drives the pusher away from the frame, creating a sufficient gap to avoid movement interference that could cause hooks. Then, the tilting cylinder controls the pallet to tilt, causing the packaging bag to slide off the pallet and fall smoothly. Compared to a direct drop, its falling potential energy is smaller, providing cushioning and preventing the packaging bag from tearing due to the impact of the fall.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-10 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0030] Example 1: To address the problems existing in the prior art, this example provides a material bag ejection mechanism for a valve bag packaging machine. It includes active rods 3 rotatably mounted on both sides of the frame 1 of the bag packaging machine. A pusher 2 is rotatably mounted on the upper ends of the two active rods 3. Driven rods 4, spaced apart from the active rods 3, are rotatably mounted on both sides of the pusher 2. A connecting plate 7, fixed to the frame 1, is rotatably connected to the lower end of each driven rod 4. Ejection cylinders 10 are rotatably mounted on both side walls of the frame 1. The extended ends of the two ejection cylinders 10 are rotatably connected to corresponding side rods. The active rods 3 and driven rods 4 form a four-bar linkage, and their dimensions satisfy the following: the pusher 2 remains vertical during deflection. A mounting plate 9 is fixed to the lower end of the pusher 2 on the side away from the frame 1. A support plate 5 is rotatably mounted on the mounting plate 9. A tilting cylinder 12 is rotatably mounted on the mounting plate 9 below the support plate 5. A connecting rod is rotatably connected to the extended end of the tilting cylinder 12. The connecting rod is fixed to the support plate 5 and rotatably mounted on one end of the pusher 2.

[0031] Principle details of this embodiment:

[0032] A material bag ejection mechanism for a valve bag packaging machine includes two drive rods 3, which are rotatably mounted on both sides of the frame 1 of the bag packaging machine. The lower ends of the two drive rods 3 are mounted on the same rotating shaft. A pusher 2 is rotatably mounted on the upper ends of the two drive rods 3. A driven rod 4 is rotatably mounted on each side of the pusher 2, located on the side of the drive rods 3 away from the frame 1 and spaced apart from the drive rods 3. A connecting plate 7 is rotatably connected to the lower ends of the two driven rods 4, and the two connecting plates 7 are welded and fixed to the frame 1. The installation positions of the drive rods 3 and driven rods 4 form a four-bar linkage mechanism, and the dimensions satisfy that the pusher 2 remains vertical when deflected.

[0033] Both sides of the frame 1 are rotatably mounted with push-out cylinders 10, and the extended ends of the two push-out cylinders 10 are rotatably connected to the corresponding side drive rods 3.

[0034] The pusher 2 has a mounting plate 9 fixed to its lower end on the side opposite to the frame 1. A support plate 5 is rotatably mounted on the mounting plate 9. A tilting cylinder 12 is rotatably mounted on the mounting plate 9 below the support plate 5. A connecting rod is rotatably connected to the extended end of the tilting cylinder 12. The connecting rod is fixed to the support plate 5 and rotatably mounted on one end of the pusher 2. The dimensions of the support plate 5 are such that it completely illuminates the fixed end of the tilting cylinder 12.

[0035] Based on the above technical solution:

[0036] In use, the packaging bag containing powder is placed on the pallet 5, and then the bag opening is sealed by the sealing device. After sealing, the push cylinder 10 extends and pushes the drive rod 3 counterclockwise. The deflection of the drive rod 3 causes the driven rod 4, push frame 2, and pallet 5 to shift towards the main frame 1. This removes the packaging bag from the frame 1, creating sufficient safety space. At this time, the tilting cylinder 12 extends and tilts the pallet 5 through the connecting rod. The packaging bag slides off the pallet 5 under its own weight and is unloaded, completing the unloading process.

[0037] The entire process begins with the pusher cylinder 10 driving the pusher 2 away from the frame 1, creating a sufficient gap to avoid movement interference. Then, the tilting cylinder 12 controls the tray 5 to tilt, causing the packaging bag to slide off the tray 5. Compared to a direct fall, its falling potential energy is smaller, providing cushioning and preventing the packaging bag from tearing due to the impact of the fall.

[0038] In a further embodiment of this solution, the upper sides of the push frame 2 are provided with triangular support plates 8 on the side facing away from the frame 1. The upper end of the driven rod 4 is rotatably mounted on the triangular support plate 8. An extension plate facing the frame 1 is fastened to the side of the triangular support plate 8. The upper end of the driving rod 3 is rotatably mounted on the end of the extension plate.

[0039] The triangular support plate 8 provides a mounting base for the driven rod 4 and the driving rod 3, while ensuring sufficient clearance between the driving rod 3 and the driven rod 4 so that the push frame 2 remains vertical when it flips.

[0040] In Example 3, a further embodiment of this solution, the driving rod 3 and the driven rod 4 are staggered. Furthermore, the rotational connection between the ejector cylinder 10 and the driving rod 3 is symmetrical to the driven rod 4 along the driving rod 3, avoiding positional interference due to flipping and ensuring the smooth operation of the equipment.

[0041] In Example 4, a further embodiment of this solution, a transverse cylinder 11 is fixedly installed on each of the two triangular support plates 8, and the extended ends of the two transverse cylinders 11 are arranged opposite to each other and are fixedly installed with clamping plates 6.

[0042] Two horizontal cylinders 11 control the opening and closing of two clamping plates 6 to hold and fix the packaging bag. This ensures the packaging bag remains stable during sealing and the offset of the pusher 2, preventing it from falling or shifting. Before the tray 5 flips, the clamping plates 6 loosen their grip, allowing the packaging bag to relax.

[0043] In Example 5, a further embodiment of this solution, the clamping plate 6 is bent along the axis of the pusher 2 on one side facing the frame 1, and a locking post is fixed at the other end. This restricts the packaging bag on both sides except for the straight side of the clamping plate 6, preventing the packaging bag from tilting to one side.

[0044] Example 6, a further embodiment of this solution, refers to the appendix. Figure 10 As shown, the mounting plate 9 has a notch, and the extended end of the tilting cylinder 12 passes through the notch and connects to the connecting rod. The tilting cylinder 12 is not suspended, ensuring the installation stability of the tilting cylinder 12, and thus ensuring the lifting stability of the packaging bag.

[0045] Example 7, a further embodiment of this solution, wherein the side wall of the active rod 3 is provided with multiple adjustment holes that are hinged to the extended end of the push-out cylinder 10. (See attached diagram) Figure 7 As shown, multiple adjustment holes are distributed along the length of the drive rod 3, and the extended end of the ejector cylinder 10 is connected to the adjustment holes via pre-drilled bolts. By changing the hinged connections of the extended end of the ejector cylinder 10 to different adjustment holes, the deflection angle of the drive rod 3 can be adjusted, thereby controlling the ejection distance.
