Description

Technical Field

[0001] This utility model relates to the technical field of ton bag packaging machines, specifically to a bag hanging device and a ton bag packaging machine. Background Technology

[0002] BOOM (Flexible Intermediate Bulk Container), also known as a flexible container bag or space bag, is a medium-sized bulk container and a type of unitized container. When used in conjunction with cranes or forklifts, it enables efficient unitized transport.

[0003] Before operation, ton bag packaging machines require the four corner straps of the ton bag to be suspended from the bag-hanging device below the machine. However, the bag-hanging devices currently available on the market are complex and relatively bulky. For example, Chinese patent CN222022977U discloses a bag-hanging mechanism and a ton bag packaging machine. The bag-hanging mechanism includes a hook and a stop. The hook can rotate around a hinged position under the drive of a drive cylinder to achieve bag hanging and unloading. The hook itself has a concave cavity for hanging the ton bag, which is not closed and has an opening for the ton bag to be hung. During the filling operation, as the material inside the ton bag gradually increases, the increased weight causes the hook to straighten and may compress the stop, causing it to deform inward and become damaged. This not only increases the difficulty of the operator's work but also poses a risk of tipping over during transport due to the hook's inability to disengage properly.

[0004] Therefore, simplifying the structural design of the existing bag hanging device of the ton bag packaging machine, while improving the operational stability of the unhooking operation, is one of the technical problems that urgently need to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a bag hanging device and a ton bag packaging machine, which can solve the problems of complex structure and easy damage and failure of the bag hanging device of the ton bag packaging machine in the prior art.

[0006] To achieve the above and other objectives, this utility model is implemented through the following technical solution: As a first aspect, this utility model proposes a bag hanging device, including a mounting frame; a side sliding sleeve installed at one end of the mounting frame; a main sliding sleeve installed at the other end of the mounting frame and coaxially arranged with the side sliding sleeve; a gap is formed between the side sliding sleeve and the main sliding sleeve for inserting a ton bag lifting strap; a bag hanging shaft slidably installed in the main sliding sleeve; and a driving device connected to the bag hanging shaft for driving the bag hanging shaft to slide in the main sliding sleeve and pushing the bag hanging shaft into the side sliding sleeve.

[0007] In one embodiment, a rotating plunger is installed on the main sliding sleeve, and a limiting groove is provided on the bag hanging shaft. When the rotating plunger is inserted into the limiting groove, the rotating plunger locks the bag hanging shaft in a retracted state.

[0008] In one embodiment, the mounting bracket includes a first fixed plate, a first side plate, a second side plate, and a third side plate, wherein the first side plate, the second side plate, and the third side plate are vertically mounted on the lower end surface of the first fixed plate from left to right; the side sliding sleeve is mounted on the first side plate, and the two ends of the main sliding sleeve are respectively mounted on the second side plate and the third side plate.

[0009] In one embodiment, a second fixing plate is installed on the upper surface of the first fixing plate with fixing bolts, and the bag hanging device is clamped and installed on the ton bag packaging machine by the first fixing plate and the second fixing plate.

[0010] In one embodiment, the mounting bracket is provided with a handle.

[0011] In one embodiment, the two ends of the handle are respectively mounted on the second side plate and the third side plate.

[0012] In one embodiment, the driving device is a single-acting cylinder, and its guide rod is connected to the bag hanging shaft.

[0013] In one embodiment, the drive device is fixedly mounted on the third side plate via a mounting bracket.

[0014] As a second aspect, this utility model proposes a ton bag packaging machine, including the bag hanging device as described in the first aspect.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0029] like Figure 1 As shown, this utility model provides a bag hanging device, including a mounting frame 10, a side sliding sleeve 20, a main sliding sleeve 30, a bag hanging shaft 40, and a driving device 50. The side sliding sleeve 20 is installed at one end of the mounting frame 10, and the main sliding sleeve 30 is installed at the other end of the mounting frame 10 and is coaxially arranged with the side sliding sleeve 20. A gap is formed between the side sliding sleeve 20 and the main sliding sleeve 30 for inserting the ton bag lifting strap. The bag hanging shaft 40 is a cylinder and is slidably installed in the main sliding sleeve 30. The driving device 50 is fixedly installed on the mounting frame 10, and its guide rod 51 is connected to one end of the bag hanging shaft 40 for driving the bag hanging shaft 40 to slide in the main sliding sleeve 30 and can push the bag hanging shaft 40 into the side sliding sleeve 20.

[0030] like Figure 1 and 3 As shown, in order to lock the retracted state of the bag hanging shaft 40, a rotary plunger 60 can be installed on the main sliding sleeve 30, and a limiting groove 41 can be provided on the bag hanging shaft 40. When the rotary plunger 60 is inserted into the limiting groove 41, the rotary plunger 60 can prevent the displacement of the bag hanging shaft 40 and lock the bag hanging shaft 40 in the retracted state.

[0031] like Figure 2 As shown, the mounting bracket 10 may include a first fixed plate 11, a first side plate 12, a second side plate 13, and a third side plate 14. The first side plate 12, the second side plate 13, and the third side plate 14 are vertically mounted on the lower end surface of the first fixed plate 11 from left to right. The side sliding sleeve 20 is mounted on the first side plate 12, and the two ends of the main sliding sleeve 30 are respectively mounted on the second side plate 13 and the third side plate 14. The detachable design of the first side plate 12, the second side plate 13, and the third side plate 14 allows for easy adjustment of the installation distance between the side sliding sleeve 20 and the main sliding sleeve 30.

[0032] Furthermore, in order to facilitate the adjustment of the installation position of the bag hanging device on the ton bag packaging machine to accommodate ton bags of different sizes, a second fixing plate 15 can be installed on the upper end face of the first fixing plate 11 with fixing bolts 16. The bag hanging device is clamped and installed on the ton bag packaging machine by the first fixing plate 11 and the second fixing plate 15, and the position can be adjusted by loosening the fixing bolts 16.

[0033] like Figure 1As shown, in order to facilitate the installation and operation of the bag hanging device, a handle 17 can be added to the mounting frame 10. Specifically, the two ends of the handle 17 can be installed on the second side plate 13 and the third side plate 14 respectively.

[0034] like Figure 2 As shown, the drive unit 50 can be a single-acting cylinder, with its guide rod 51 connected to the bag hanging shaft 40. To improve the installation stability of the drive unit 50, the drive unit 50 can be fixedly mounted on the third side plate 14 via the mounting base 52.

[0035] In summary, the working process of the bag-hanging device provided by this utility model is as follows: Figure 2 and Figure 3 As shown, when packaging begins, the bag-hanging shaft 40 is locked in the retracted state by the rotating plunger 60. The operator places the ton bag lifting strap into the space formed between the side sliding sleeve 20 and the main sliding sleeve 30. Manually pulling out the knob plunger 4 releases the limit on the bag-hanging shaft 40, at which point the guide rod 51 of the drive device 50 can push the guide rod shaft 10 into the side sliding sleeve 20 (e.g., ...). Figure 4 As shown), the ton bag lifting strap is locked, and the bag hanging is completed; after packaging is completed, the drive device 50 vents and pushes the bag hanging shaft 40 back into the main sliding sleeve 30 through the guide rod 51, and the ton bag lifting strap automatically falls off, completing the bag unhooking process.

[0036] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
