Description

Technical Field

[0001] This utility model belongs to the field of strapping machines, specifically relating to an automatic knot-tying device. Background Technology

[0002] A strapping machine is a device that uses flexible rope to bundle and knot materials. It mainly includes a guide rod for the strapping rope, a rope unwinding mechanism, and a knotting mechanism. The knotting mechanism includes components such as a rope clamp, knotting pliers, and a rope cutter.

[0003] Existing strapping machines work by placing materials into their workstations and then strapping them together. However, some materials are not suitable for strapping on these machines, such as the pipes of refrigerator condensers. These pipes are complex and curved after forming, requiring rope loops for separation during stacking. It is also inconvenient to place them into the strapping machine one by one. The strapping machine needs to automatically form knotted rope loops even when there are no materials, and then place the finished rope loops directly onto the condenser pipe production line for strapping. Therefore, existing strapping machines lack the function of automating the production of rope loops. Utility Model Content

[0004] The purpose of this invention is to provide an automatic knot-tying device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

The base also includes a support mechanism and a track assembly for moving the support mechanism. The support mechanism includes a base, a hinge seat disposed on the base, and support rods hinged to the hinge seat and arranged in a circular array. The support rods are used to simulate material as the basis for generating the rope loop. A telescopic rod is provided axially on the base, and a connecting rod is provided between the end of the telescopic rod and the support rod for driving the support rod to rotate towards the center of the array.

[0007] As a further optimization of this utility model, the telescopic rod is driven by a cylinder installed in the base. Specifically, the telescopic rod is extended and retracted by a cylinder, but other components can also be used for driving. For this purpose, the base is shaped as two coaxially connected cylinders of different sizes. The larger cylinder is used to connect the support rod, and the smaller cylinder is used to accommodate the cylinder and is connected to the connecting seat.

[0008] As a further optimization of this utility model, the track assembly includes a slide rail disposed on one side of the base, a sliding member with a drive on the slide rail, and a connecting seat for connecting to the base on the sliding member. The track assembly is used to unload the material by moving the support mechanism away from the binding area. The slide rail can be driven by a pneumatic drive source or by a servo system threaded screw.

[0009] As a further optimization scheme of the utility model, the slide rail and the slide piece are both two, the connecting seat is arranged between the two slide pieces to form a space below the supporting mechanism, and the knotted rope sleeve is conveniently dropped.

[0010] As a further optimization scheme of the utility model, the base and the surface of the connecting seat butt joint are provided with two side rods on each side, the inner side surface of the connecting seat is provided with a side groove corresponding to the two side rods, the side groove is divided into two sections, one section is horizontal and the other section is inclined, the slide rail is provided with a baffle at one end extending upward, the baffle is provided with a tension spring connected with the base, the tension spring is used for pulling the base to make the two side rods enter the horizontal section of the side groove when the base is away from the baffle, in order to further conveniently drop the rope sleeve after knotting, the scheme has the function of being inclined downward when the supporting mechanism reaches the unloading area, and the function is realized through the side rods and the side groove on the two sides.

[0011] As a further optimization scheme of the utility model, the baffle is further provided with a limiting piece, which is used for abutting against the base to make one of the side rods enter the inclined section of the side groove when the connecting seat is close to the baffle.

[0012] The utility model has the advantages that:

[0013] The utility model discloses a supporting rod is arranged as an analog material and is put into a bundling machine to be bundled to form a rope sleeve, then the supporting rod is rotated along the hinge seat to the array center to make the cylindrical structure formed by the supporting rod become a circular truncated cone structure, and the tightly bundled rope sleeve is loosened and dropped, thereby playing the role of producing and collecting the rope sleeve.
