However, it is found in actual use that the clamp and the binding device of such equipment are usually fixed, that is, they can only adapt to a single specification of plastic packing box. Once the size of the plastic packing box changes, it cannot be used, and the versatility is poor. SUMMARY

[0004] The purpose of the present application is to solve the problem that the clamp and the binding device of the binding equipment in the prior art are usually fixed, that is, they can only adapt to a single specification of plastic packing box. Once the size of the plastic packing box changes, it cannot be used, and the versatility is poor.

[0005] To solve the above problems, the present application provides an adjustable automatic binding equipment, which comprises a base frame, and further comprises:

[0006] A trigger is arranged on the front side of the base frame.

[0007] A clamp assembly comprises an adjusting disc and at least two clamping seats. All the clamping seats are distributed around the trigger and are slidably connected to the front side of the base frame in the radial direction with the trigger as the center. The clamping seats protrude forward and have positioning tables for abutting and positioning workpieces. The adjusting disc is rotationally connected to the rear side of the base frame and has a rotational axis along the front-rear direction and coaxial with the trigger. The adjusting disc is provided with connecting rods corresponding to the clamping seats in the circumferential direction. The connecting rods are rotationally connected to the outer edge of the adjusting disc at the first end and are provided with adjusting holes at the tail end.

The clamping seats are provided with screw holes facing the long holes. The bolts pass through the corresponding long holes and are screwed to the screw holes of the corresponding clamping seats. When the bolts are loose, the adjusting disc drives the connecting rods to move by forward and reverse rotation, and the connecting rods drive the clamping seats to move closer to or away from each other through the bolts. When the bolts are locked, the clamping seats and the connecting rods are locked relative to the base frame.

[0008] The front side of the base frame is connected with a bracket, the bracket is located below the clamping seat and extends forward, and the upper side of the bracket is provided with a rest table for resting the workpiece;

[0009] The binding assembly corresponds to the clamping seat one by one, the binding assembly comprises a binder and a linear drive connected to the base frame, the binder is connected to the output end of the corresponding linear drive and is driven by the linear drive to approach or move away from the corresponding clamping seat, the binder has a nail head facing the positioning table of the corresponding clamping seat, when the trigger is triggered, the linear drive drives the binder to approach the positioning table, and the binder binds the workpiece.

[0010] Compared with the prior art, the clamping seat is designed to be slidably connected to the front side of the base frame, when the model size of the workpiece such as a plastic packaging box changes, the bolt is loosened by rotating, and the adjusting disc is forward or reverse rotated, at this time, the tail end of the connecting rod pushes the clamping seat to approach or move away from the center of the adjusting disc, that is, the clamping seats approach or move away from each other, after adjustment, the bolt is locked, so that the positioning table of the clamping seat can be adapted to and abutted to the inner wall of the workpiece of different model sizes to fix the workpiece, and the universality is effectively improved; and the binder is driven by the linear drive to approach or move away from the corresponding clamping seat, so that even if the spacing between the positioning tables of the clamping seats changes, the binder can still ensure that the workpiece on the positioning table is bound, and the use is simple and convenient.

[0011] In an improved scheme, the clamping seat is four and is located at the upper, lower, left and right of the front side of the base frame, and the trigger is located in the middle of the front side of the base frame, considering that the plastic packaging box is mostly square tubular, four clamping seats are provided, and the positioning tables of the four clamping seats are respectively abutted and positioned to the four inner walls of the plastic packaging box.

[0012] In an improved scheme, the middle of the rear side of the adjusting disc is provided with a limiting table protruding rearward, the outer peripheral wall of the limiting table is provided with an arc-shaped surface concave at a position corresponding to the leading end of each connecting rod, and the leading end of the connecting rod has a rounded corner to slide and abut against the corresponding arc-shaped surface, so that when the adjusting disc is forward or reverse rotated, the arc-shaped surface of the limiting table can support the leading end of the connecting rod to a certain extent, and the structural stability is improved.

[0013] In an improved scheme, the adjusting disc is provided with a hexagonal column table extending rearward, so that the rotation of the adjusting disc can be realized by the cooperation of the wrench and the hexagonal column table, and the operation is simple and convenient.
