Description

Technical Field

[0001] This utility model relates to the field of automatic packaging machine technology, specifically a strapping and tightening lifting device. Background Technology

[0002] In the field of automatic packaging machine technology, bundling and packaging items is a common operational procedure. During the bundling process, the tightening and lifting of the strapping is a crucial step, and its stability and efficiency directly affect the quality and effectiveness of the packaging. However, existing strapping tightening and lifting devices have some problems in practical use. For example, the tightening effect on the strapping is poor, easily causing the strapping to slip during tightening, affecting the strength of the bundling; or the structural design of the device is not reasonable enough, making the tightening and lifting action not smooth, reducing packaging efficiency. These problems make it difficult for existing strapping tightening and lifting devices to meet the needs of efficient and stable packaging. Therefore, we have introduced a strapping tightening and lifting device to solve the above problems. Utility Model Content

One side of the mounting bracket is provided with an inwardly inclined slope. The side of the mounting bracket away from the slope is provided with a feeding port and a discharging port.

[0009] The pressure tongue is strip-shaped, with one end hinged in the mounting bracket and the other end extending to the outside of the slope. A connecting post is provided on one side of the pressure tongue, and the connecting post slides in contact with the slope.

[0010] A compression spring, one end of which is connected to the outer side of the side plate and the other end of which is connected to a connecting post; and

[0011] A cylinder, the drive end of which is hinged to the mounting bracket.

[0012] Preferably, the feeding port is rectangular and cylindrical, with its bottom end inserted into the port of the perforated connecting bucket. The bottom end of the connecting bucket has a feeding outlet, which is flat.

[0013] Preferably, the linear guide rail is provided with a first limiting block and a second limiting block at both ends.

[0014] Preferably, the driving end of the cylinder is provided with a transfer bracket, which is hinged to the L-shaped base frame via a hinge shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The beneficial effects of this invention are mainly reflected in its reasonable structural design, which achieves effective tightening and lifting of the strapping tape, ensuring the stability and efficiency of the strapping operation, as detailed below:

[0020] Good clamping effect: The bottom end face of the pressure tongue has a bevel and an arc surface, and there are several protrusions on the arc surface, which can enhance the friction of the strapping, prevent slippage, and ensure a firm binding.

[0021] Smooth and efficient operation: The cylinder drives the mounting bracket to slide on the linear guide rail. Combined with the hinged design of the pressure tongue and the tension of the pressure spring, the tightening and lifting actions are smooth and continuous, improving packaging efficiency.

[0022] The structure is reasonably designed: the feeding port is a rectangular cylinder, and the bottom end is inserted into the hole-shaped connecting bucket port. The belt outlet at the bottom of the connecting bucket is flat. This design facilitates the introduction and export of strapping and ensures the stability of strapping conveying.

[0023] Limit protection: The first and second limit blocks at both ends of the linear guide rail can prevent the mounting bracket from sliding excessively, thus playing a limit protection role and ensuring the safe operation of the device.

[0024] Stable connection: The side plate of the mounting bracket is connected to the L-shaped base frame by bolts, and the hinge bracket at the cylinder drive end is hinged to the L-shaped base frame by a hinge shaft, so that the connection of each component is stable and the overall performance of the device is reliable.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 2 This utility model provides a technical solution: a strapping band tightening and lifting device, including a mounting platform 1, a linear guide rail 2, a mounting bracket 3, a pressure tongue 4, a clamping spring 5, and a cylinder 6. The linear guide rail 2 is mounted on the mounting platform 1, the mounting bracket 3 is slidably mounted on the linear guide rail, the pressure tongue 4 is hinged to the mounting bracket, and the pressure tongue 4 is used to tighten the strapping band during operation. The cylinder 6 is mounted on one side of the mounting platform.

[0030] In an embodiment of this utility model, the mounting bracket 3 includes an L-shaped base frame 31 and a side plate 32. The side plate 32 is bolted to the L-shaped base frame 31. One side of the mounting bracket 1 is provided with an inwardly inclined slope 33. The side of the mounting bracket away from the slope is provided with a feeding port 34 and a discharging port 35.

[0031] In an embodiment of this utility model, the feeding port 34 is a rectangular cylinder, with its bottom end inserted into the port of the hole-shaped connecting bucket 36. The bottom end of the connecting bucket 36 is provided with a feeding port 34, which is flat.

[0032] In an embodiment of this utility model, the pressure tongue 4 is strip-shaped, with one end hinged in the mounting bracket 3 and the other end extending to the outside of the slope 33. A connecting post 41 is provided on one side of the pressure tongue 4, and the connecting post 41 slides in contact with the slope 13.

[0033] In this embodiment of the invention, one end of the compression spring 5 is connected to the outer side of the side plate, and the other end is connected to the connecting post. The compression spring 5 is used to tighten the pressure tongue 4.

[0034] In this embodiment of the invention, the driving end of the cylinder 6 is hinged to the mounting bracket 1. Specifically, the driving end of the cylinder 6 is provided with a connecting bracket 61, which is hinged to the L-shaped base frame 31 via a hinge shaft 62.

[0035] In an embodiment of this utility model, the two ends of the linear guide rail 2 are respectively provided with a first limiting block 21 and a second limiting block 22.

[0038] In this embodiment of the invention, the working principle is as follows: The mounting platform 1 is installed at a suitable position on the strapping machine. The strapping tape enters from the feeding port 14 and extends from the output port 15 into the strapping station of the strapping machine. The cylinder 6 drives the pressure tongue to tighten the strapping tape, and the strapping machine begins packaging. After packaging is completed, the cylinder 6 retracts, and the pressure tongue leaves the strapping tape. Since the end of the strapping tape connected to the strapping machine is still inside the machine, the feeding port 14 rises, generating tension at the end of the strapping tape connected to the machine, causing the strapping tape to be pulled out from the output port after entering from the feeding port. Before the next packaging begins, the cylinder 6 drives the pressure tongue to press down again, tightening the strapping tape. This process is repeated to tighten and lift the strapping tape.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
