Definitions

  • the invention relates to the field of strapping machines, and in particular to a strap tensioning device for a strapping machine. Background technique
  • the strapping machine is a device for binding articles with a strapping strap
  • the strapping tensioning device is a device for tightening the strapping strap when the strapping strap is attached.
  • the conventional strap tensioning device comprises a swing arm controlled by a cam, and a pawl of the strap is arranged on the swing arm, and the timing of the gripping of the strap during the swinging of the swing arm is controlled by another adjustable cam mechanism. Therefore, the stroke of the swing arm to control the movement of the strap is controlled to control the tension of the strap.
  • the tension of the strapping belt is limited by the swinging stroke of the swing arm, and the adjustment range is limited.
  • the adjustment of the adjustable cam mechanism is entirely based on experience, and it is easy to cause the bundle of the same batch of articles. It’s not tight. Summary of the invention
  • the technical problem to be solved by the present invention is to provide a strap tensioning device for a strapping machine having a wider adjustment range of tension and a high degree of retractability.
  • the utility model adopts the following technical solutions: it comprises a first entraining roller driven by a motor and a second entraining roller matched with the first entraining roller, the second entraining roller is provided with an eccentric shaft, and the packing belt is pulled The tightening device is provided with a mechanism for driving the rotation of the eccentric shaft.
  • DRAWINGS 1 is a schematic view showing the structure of one side of a strapping machine according to an embodiment of the present invention.
  • Figure 2 is a schematic illustration of the structure of the embodiment of Figure 1 on the other side of the strapping machine.
  • Figure 3 is a front elevational view of the embodiment of Figure 1 on the side of the strapping machine.
  • Figure 4 is an enlarged view of A of Figure 1.
  • the invention comprises a first entrainment roller 2 driven by a motor 1 and a second entrainment roller 3 cooperating with a first entrainment roller, the shaft 31 of the second entrainment roller being an eccentric shaft, and the strap tensioning device being provided with a drive The mechanism by which the eccentric shaft rotates.
  • the driving of the eccentric shaft can be rotated in a variety of ways, such as using a cylinder and a corresponding mechanical connection.
  • the mechanism for driving the eccentric shaft rotation in this embodiment includes a rotary trigger arm 4 of the eccentric shaft, a link 7 connected to the wrench arm, a cam 5 for controlling the movement of the link, and a return spring 6 for the wrench arm.
  • the connecting rod is a flexible connecting rod supported by a compression spring, so that the clamping force of the first entraining roller and the second entraining roller on the packing belt can be automatically adjusted according to the difference of the packing belt.
  • the connecting rod includes a straight line segment 71 and a rotating portion 72 that cooperates with the cam 5.
  • the straight line segment is a flexible rod supported by the compression spring 73.
  • One end of the straight line segment is rotatably connected to one end of the rotating portion.
  • the other end of the straight section is rotatably coupled to the arm.
  • the straight section includes a rod 74 and a rod 75 that is inserted into the rod 75 with a compression spring disposed between the rod 74 and the rod 75.
  • the rotating section 72 When in use, the rotating section 72 is rotated by the action of the cam, and the straight section 72 is moved to the right direction of FIG. 3, thereby driving the trigger arm to rotate counterclockwise in FIG. 3, thereby driving the eccentric shaft 31 to rotate, so that the second The entraining roller 3 rotates toward the first entraining roller 2 to clamp the strap.
  • the first entraining roller When the first entraining roller cooperates with the second entraining roller to clamp the strap, the first entraining roller can actively tighten the strap after being driven by the motor.
  • the number of rotations or the angle of rotation determines the degree of tension of the strap, and the adjustment of the number of revolutions or the angle of rotation can be achieved by digitally controlling the rotation of the motor.
  • Reference numeral 76 is a bearing roller on the rotating section 72 which is in contact with the cam.
  • reference numeral 8 is a mounting plate in the binding machine to which the tensioning mechanism is mounted.

Abstract

L'invention porte sur un appareil de tension de feuillard de mise en balles d'une machine de cerclage, qui comprend le premier rouleau entraîné par un moteur électrique et le second rouleau qui se couple au premier rouleau. Ledit second rouleau comporte un arbre excentrique, ledit appareil de tension comportant un mécanisme de rotation entraînant l'arbre excentrique. Le degré de déformation des feuillards de mise en balles est commandé par la rotation du moteur électrique par l'intermédiaire du nombre de rotations du cylindre ou de l'angle d'oscillation du premier rouleau.
