Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a binding limiting mechanism for corrugated paper boxes. Background Art

[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, stapling or gluing. Corrugated boxes are the most widely used packaging products and have always been the most used of all packaging products, including calcium plastic corrugated boxes. With their superior performance and good processing properties, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers and become the main force of transport packaging. The last step of the corrugated box manufacturing process is box forming, that is, workers glue or staple the boxes together. In this process, a binding machine is needed to bind the corrugated boxes. The existing technology has the following problems:

[0003] Chinese patent document CN220332096U provides a limiting mechanism for a corrugated cardboard box binding machine, which relates to the field of corrugated cardboard box binding technology, including a fixed plate, a second groove is provided on the top of the fixed plate, a slide rail is connected inside the second groove, one end of the slide rail is slidably connected to a slider, the other end of the slider is connected to a binding mechanism, a threaded hole is provided on the top of the fixed plate, and the internal thread connection of the threaded hole is connected by a screw rod. The utility model starts the first motor to rotate the screw rod connected to the bottom of the first motor, so that during the rotation of the screw rod, the fixed plate moves on the surface of the screw rod under the action of the threaded hole provided on the top, and the second groove provided on the surface of the fixed plate enables the slider connected to one end of the binding mechanism to move under the action of the slide rail connected inside the second groove, so that the binding can be in a straight line, which greatly improves the aesthetics.

[0004] In the above-mentioned document, a screw is used to drive the fixed plate to descend so as to suppress and limit the top of the corrugated cardboard box. However, only a telescopic rod is provided on the front side of the corrugated cardboard box, which results in that the front and rear positions of the corrugated cardboard box cannot be effectively limited, affecting the binding effect. At the same time, due to the limitation of the electric push rod and the push plate, each time the corrugated cardboard box is bound, it can only be taken out again manually, and then a new unbound corrugated cardboard box is placed under the fixed plate again. The operation steps are relatively cumbersome, affecting the binding efficiency. Utility Model Content

At this time, the left and right limiting clamping plates 14 can be completely moved out to the top of the carton placement plate 1. Then, the double-axis motor 132 in the left and right slide grooves 131 opened on the tops of the left and right clamping boxes 13 can be driven to rotate the threaded rods 133 connected to the output ends on the left and right sides. The threaded rods 133 with opposite threads and the threaded plates 134 of the translation plate 134 are used to rotate. The connection can drive the two left and right limit clamps 14 to clamp the left and right sides of the corrugated paper box, so that it is located in the center position below the limit binding plate 25 and is limited and fixed. At this time, the binding motor 253 can be directly started to drive the reciprocating screw 254 in the driving groove 252 to rotate, and the driving plate 255 is connected to the threaded connection of the outer wall of the reciprocating screw 254 to make the binding mechanism 256 move back and forth in the binding moving groove 251 to perform binding work on the top of the corrugated paper box below. After the binding is completed, the front and rear limit clamps 259 are released from the limit of the corrugated paper box by starting the output shaft of the clamping motor 258 to reverse, and the electric push rod 23 is started to drive The overall limit binding plate 25 rises, and then the double-axis motor 132 in the left and right clamping boxes 13 is started to reverse its output shaft, thereby releasing the left and right limit clamps 14 from limiting the corrugated cardboard box in the left and right directions. Then, the electric push rod 2 121 is started to make the two left and right limit clamps 14 descend until they completely enter the I-shaped groove 11. At this time, the rotating motor 32 at the bottom of the extension plate 31 is started to drive the discharge push plate 33 to rotate, and the corrugated cardboard box bound on the carton placement plate 1 is knocked forward to several sliding rollers 42 between the two inclined side plates 41. By rotating the sliding rollers 42, the bound carton can slide smoothly to the discharge platform 43 to complete the discharge.

[0033] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention.
