Description

TECHNICAL FIELD

[0001] The present application relates to the field of learning office supplies, and particularly relates to an electric control automatic staple extractor. BACKGROUND

[0002] Staplers are widely used in daily learning and office work, and splitting of the bound documents also occurs from time to time. The process of removing staples is time-consuming and laborious, and sometimes can cause injury to the nails or fingers. The bound staples can also cause injury to the human body if they are ejected. Most of the existing staple extractors are laborious to use. For example, a staple extractor disclosed in Chinese patent CN 113319793 A is based on the principle that the staple is ejected from the document by a staple extraction needle with a certain curvature, and the staple extraction action still needs to be completed manually, and the problem of time-consuming and laborious is not fundamentally solved. A new type of paper shredder for automatically removing staples is disclosed in Chinese patent CN 204892058 U, and the principle is that the movable staple is taken down by the upper and lower clamps. However, the main body of the device is still a paper shredder, and the staple extraction mechanism cannot work independently and cannot be used in other situations except for the paper shredder. A multifunctional automatic staple extractor is disclosed in Chinese patent CN 112873135 A, and the principle is that the automatic clamping and pulling realize automatic staple extraction. However, the device still needs the operator to perform the action of hand gripping and opening and closing, and long-time operation is time-consuming and laborious. SUMMARY

[0003] In order to solve the problems of the prior art, the present application provides an electric control automatic staple extractor, which realizes automatic staple extraction by controlling the position of the clamp and the action of the clamp. The technical scheme of the present application is as follows:

[0004] The present application discloses an electric control automatic staple extractor, which is characterized by being composed of a driving module, a transmission module and an execution module. The driving module comprises a lifting motor, an opening and closing motor, a lifting motor mounting seat, an opening and closing motor mounting plate, a thrust bearing seat, a shaft coupling and a main body mounting seat. The transmission module comprises a flange nut, a flange nut connecting plate, a long suspension shaft, a short suspension shaft, a guide shaft support, a suspension table and an opening and closing motor balance plate. The execution module comprises a fastening ring, a connecting column, a connecting knob, a clamp rotating shaft, a large clamp arm, a small clamp arm and a distance switch.

[0005] In the driving module of the electric control automatic staple extractor, the lifting motor is installed on the lifting motor mounting seat in a vertical downward manner of the rotating shaft, the lifting motor mounting seat is π-shaped, the lifting motor rotating shaft is inserted into the thrust bearing seat, and the thrust bearing seat is installed on the main body mounting seat.

[0006] In the driving module of the electric control automatic staple extractor, the opening and closing motor is installed on the opening and closing motor mounting plate, the opening and closing motor mounting plate is L-shaped, and the opening and closing motor rotating shaft is connected with the clamp rotating shaft through the shaft coupling.

[0007] The flange nut of the transmission module of the electric control automatic nail extractor is installed on the rotating shaft of the lifting motor, and the rotating shaft of the lifting motor and the flange nut form a screw nut mechanism, which converts the rotary motion of the rotating shaft of the lifting motor into the linear motion of the flange nut. The flange nut is connected by bolts in sequence from bottom to top to fix the flange nut connecting plate, the long suspension shaft, the short suspension shaft, the opening and closing motor balance plate, the guide shaft support, the suspension table and the opening and closing motor mounting plate. The suspension table, the short suspension shaft, the flange nut connecting plate, the long suspension shaft and the opening and closing motor balance plate form a carrying pole structure, which ensures the stability of the lifting motion.

[0008] The fastening ring of the execution module of the electric control automatic nail extractor is installed and fixed at the lowermost end of the short suspension shaft. The fastening ring is circular with a 30° notch. The notch of the fastening ring is used to clamp the large and small clamp arms. The large and small clamp arms are sequentially provided with a fixed section, a hinged section, a power section and a clamping section from the upper end to the lower end. The groove back of the fixed section has a clamping groove for clamping the notch of the fastening ring to realize fixation. The hinged section has a circular-arc-shaped notch in the groove opening for clamping the connecting column to realize the hinge connection of the large and small clamp arms. The groove back of the power section has a runway-shaped hole, and the clamping device rotating shaft extends from the runway-shaped hole. The groove ridge of the power section has a through circular hole, and the cylindrical connecting knob is installed in the circular hole. The clamping section is a crescent-shaped nail lifting tooth, and the nail lifting teeth of the large and small clamp arms are inserted into the gap between the staple and the document to realize the clamping action.

[0009] The electromagnetic iron is installed in the groove of the small clamp arm in the execution module of the electric control automatic nail extractor. When the clamping action is performed, the electromagnetic iron is electrified to generate electromagnetic force to attract the staple, thereby avoiding the staple from bouncing out of the nail lifting tooth and preventing safety hazards to people.

[0010] The connecting knob of the execution module of the electric control automatic nail extractor is a cylinder with an outer diameter equal to the diameter of the circular hole of the power section of the large and small clamp arms. There is a threaded hole with a diameter equal to the diameter of the clamping device rotating shaft in the axial middle of the connecting knob. On the one hand, the connecting knob has a threaded hole, which is a nut in the screw nut mechanism. On the other hand, the opening and closing action of the large and small clamp arms has an arc-shaped motion track. The connecting knob is installed in the circular hole of the large and small clamp arms. When the large and small clamp arms perform arc-shaped motion, the connecting knob rotates in the circular hole by the same angle, realizing the relative static state of the clamping device rotating shaft and the opening and closing motor rotating shaft.

[0011] The rotary shaft of the gripper in the execution module of the electric control automatic nail taking device is welded into one body by a pair of left-handed screw rods and right-handed screw rods with equal length, and the rotary shaft of the gripper is screwed into the threaded holes of the connecting knobs at both ends respectively. The rotary shaft of the gripper and the connecting knobs constitute a screw nut mechanism, which converts the rotary motion of the rotary shaft of the gripper into the linear motion of the connecting knobs. When the rotary shaft of the gripper rotates, the connecting knobs screwed with the left-handed screw rod and the right-handed screw rod respectively will produce linear motion in the direction of approaching or moving away from each other, thereby realizing the approaching or moving away of the large arm and the small arm, and realizing the clamping action and opening action of the gripper.

[0012] The electric control automatic nail taking device has the advantages of automatic nail taking, convenience, time and labor saving, and solves the problems of flying of the staple during the nail taking process and the like, avoids hurting the user, is efficient and safe.
