At the same time, the staff performs the bundling operation for a long time, which increases the labor intensity of the staff and reduces the packaging efficiency of the product. Utility Model Content

[0004] In order to improve the problem of product packaging efficiency, the present application provides an automatic strapping machine.

[0005] The present application provides an automatic strapping machine, which adopts the following technical solution:

[0007] By adopting the above technical scheme, when the product is processed and needs to be bundled and fixed, the end of the rope in the wire drum is passed through the guide space and embedded in the limiting space in turn, and the inner wall of the limiting space is pressed against the outer wall of the rope to form a limit, so that the end of the rope is limited on the limit block. At the same time, the rotating shaft rotates on the surface of the machine body, driving the guide rod to rotate around the periphery of the product, driving the rope in the wire drum to be wound around the periphery of the product, and at the same time, the automatic knotter knots and fixes the rope, so as to realize automatic bundling and fixation of the product. There is no need for staff to use ropes to wrap around the periphery of the product and perform bundling operations, which reduces the work intensity of staff, improves the packaging efficiency of the product, and thus reduces the processing cost of the product.

[0008] Optionally, the bundling assembly further comprises an automatic rope cutter, which is connected to a surface of the machine body facing the guide rod, and can cut the rope between the automatic knotter and the limit block.

[0009] By adopting the above technical solution, the automatic rope cutter is installed on the surface of the machine body facing the guide rod. When the automatic knotter completes tying the rope, the automatic rope cutter cuts the rope between the limit block and the automatic knotter.

When the automatic knotter is tying a knot, the positioning rod slides in the direction close to the automatic knotter, and the surface of the positioning rod abuts against the rope and drives the rope close to the automatic knotter, thereby improving the knotting efficiency of the automatic knotter for the rope.

[0012] Optionally, a positioning groove for the cord to be embedded is provided on the surface of the positioning rod facing the automatic knotter.

[0013] By adopting the above technical solution, when the positioning rod slides toward the direction close to the automatic knotter, the rope is embedded in the positioning groove, and the outer wall of the rope abuts against the inner wall of the positioning groove to form a limit, so that the rope is not easy to separate from the positioning rod.

[0016] Optionally, the surface of the extrusion plate facing the product is connected with an elastic strip, and the elastic strip can squeeze the surface of the product.

[0017] By adopting the above technical solution, when the extrusion plate slides towards the direction close to the product and the elastic strip squeezes the product, the pressure of the product on the elastic strip drives the elastic strip to deform, making the product less likely to be squeezed and damaged, thereby improving the bundling quality of the product.

[0021] By adopting the above technical solution, the end of the wire rope in the wire drum passes through the wheel surface of the positioning pulley and the guide space in turn and is embedded in the limiting space. The inner wall of the limiting space presses against the end of the wire rope to achieve limiting. At the same time, the wheel surface of the positioning pulley is in rolling contact with the wire rope, and rolling friction replaces sliding friction, thereby reducing the wear on the wire rope and improving the bundling quality of the product.
