Description

Technical Field

[0001] The utility model relates to the technical field of box folding machines, in particular to an anti-collision suction nozzle hook. Background Art

[0002] In the prior art, when taking out materials from paper boxes, a suction hook is usually used to take out materials. Glue is applied on the upper side of the paperboard, and then the suction hook moves to the lower side of the paperboard for adsorption, thereby driving the paperboard to move to a designated station. At this time, the suction hook not only needs to move back and forth, but also needs to move up and down. The up and down movement is usually driven by a driving member, and the driving member is usually a cylinder or an electric cylinder, and its output shaft is relatively fragile. If a collision occurs when the suction hook moves, the output shaft is easily deformed or broken, and the service life is relatively short. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an anti-collision nozzle hook, which provides a buffer by arranging an adaptive elastic positioning structure on the nozzle hook, and swings when the nozzle hook collides with each other, thereby making an adaptive adjustment to prevent hard collision, thereby increasing the service life of the lifting drive component.

[0004] The utility model discloses an anti-collision suction nozzle hook, which includes a mounting seat, a lifting frame lifted on the mounting seat, a lifting drive member for driving the lifting frame to lift and lower, and a suction nozzle hook arranged on the lifting frame, wherein the suction nozzle hook is provided with a suction hole, and is characterized in that: the lifting frame is provided with a hinge shaft, one end of the suction nozzle hook away from the suction hole is rotatably hinged on the hinge shaft, and an elastic positioning structure is also provided on the suction nozzle hook.

[0005] By adopting the above technical solution, when in use, it is assembled on a box folding machine, and the box folding machine can drive it to move forward and backward. At the same time, the suction hole of the suction nozzle hook can be moved to the lower side of the cardboard in cooperation with the lifting drive component. At this time, the suction hole on the suction nozzle hook can suck the cardboard and move it, thereby realizing the transportation of the cardboard. If the suction nozzle hook is obstructed and collides during the transportation of the cardboard, the elastic positioning structure will undergo elastic deformation, and the suction nozzle hook can rotate relatively around the hinge axis to adaptively avoid, thereby preventing a head-on collision, thereby avoiding deformation and disconnection of the output shaft of the lifting drive component.

[0006] The utility model is further configured as follows: the elastic positioning structure comprises an elastic ejector pin arranged on the nozzle hook and a positioning slot arranged on the lifting frame.

[0007] By adopting the above technical solution, the elastic ejector pin cooperates with the positioning groove, and when subjected to external force, the elastic ejector pin can be compressed to deform, thereby disengaging from the positioning groove, so that the nozzle hook can rotate relatively.

[0008] The utility model is further configured as follows: a pressing member and a pressing driving member for driving the pressing member to approach or move away from the suction hole are provided on the suction nozzle hook above the suction hole.

[0009] By adopting the above technical solution, the force of sucking the cardboard by the suction hole alone is relatively small, and the pressing member is used to press it while sucking, so that the cardboard can be better carried for transportation.

[0010] A further configuration of the utility model is that the pressing piece is made of an anti-adhesive material or is provided with a sheath made of an anti-adhesive material.

[0011] The above technical solution is adopted to facilitate the processing of the adhesive on the pressing part to prevent the adhesive from accumulating.

[0012] The utility model is further configured as follows: the lifting drive members are provided with two groups, one group is fixedly arranged on the mounting seat, and the other group is fixedly arranged on the lifting frame, and the output ends of the two groups of lifting drive members are fixedly connected.

[0013] By adopting the above technical solution, the displacement of the nozzle hook in two strokes can be controlled by two sets of lifting drive components, and the control requirements are relatively low. The output ends of the two sets of lifting drive components are relatively fixedly connected. When one set of lifting drive components is working, the other set will not hinder the movement.

[0014] The utility model is further configured as follows: a triggering member is provided at the connection of the two sets of lifting drive members, and a displacement sensor is provided on the lifting frame and the mounting seat at a position corresponding to the triggering member.

[0015] By adopting the above technical solution, it is easy to understand and control the lifting and lowering of the suction nozzle hook. BRIEF DESCRIPTION OF THE DRAWINGS

The elastic push pin 61 cooperates with the positioning slot 62, and when subjected to external force, the elastic push pin 61 can be compressed to deform, thereby disengaging from the positioning slot 62, so that the nozzle hook 3 can rotate relatively. Of course, the elastic positioning structure can also be a tension spring or a spring.

[0025] The nozzle hook 3 is provided with a clamping member 8 and a clamping driving member 9 driving the clamping member 8 to approach or move away from the suction hole 4 above the suction hole 4. The force of sucking the cardboard by the suction hole 4 alone is relatively small. The clamping member 8 is used to compress the cardboard while sucking, so that the cardboard can be better carried for transportation.

[0026] The clamping member 8 is made of anti-adhesive material or is provided with a sheath made of anti-adhesive material, so as to facilitate the processing of adhesive on the clamping member 8 and prevent adhesive accumulation. The most preferred anti-adhesive material is Teflon material, which can be purchased directly on the market and will not be introduced in detail in this article.
