Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an electric scissors. Background Art

[0002] Electric scissors are an electric cutting tool, mainly used for fast and precise cutting of various materials. Its working principle is to drive the blade or shear system to reciprocate or rotate through the built-in electric motor, so as to achieve efficient cutting. Electric scissors are widely used in the fields of clothing making, leather processing and home fabrics.

[0003] Existing electric scissors, for example, Chinese patent literature discloses an electric cutting scissors [patent number: 201210146994.9; application publication number: CN102644193B], which includes a frame, a cutting mechanism, a chassis mechanism and a motor control system. The chassis mechanism is installed at the lower part of the frame, the cutting mechanism includes a disc knife and a lower knife, a brushless motor housing is provided on the frame, the armature coil winding of the brushless motor is pasted in the motor housing, one end of the rotor shaft of the brushless motor is installed in the bearing at the rear end of the motor housing, and the other end is installed in the bearing on the motor cover, the rotor shaft protrudes from the frame disc, the Hall sensor is installed at the outer end of the rear end of the motor housing, and the disc knife in the cutting mechanism is directly installed on the rotor shaft of the brushless motor.

[0004] The electric scissors of this structure include a chassis mechanism, a frame and a disc knife, wherein the frame is fixedly connected to the chassis mechanism, the disc knife is installed on the frame, and the frame is located at the side of the disc knife. After the disc knife rotates, it will cut the cloth and move the cloth toward the two sides of the disc knife. However, since the bottom of the frame is located at the side of the disc knife, in order to prevent the cut cloth from being embedded between the bottom of the frame and the disc knife bracket, an elastic sheet is fixedly connected to the frame, and one piece of the elastic sheet is elastically attached to one side of the disc knife, so that the cut cloth can be separated. However, since the elastic sheet is attached to one side of the disc knife, the friction between the elastic sheet and the disc knife is large, the noise is large, and the disc knife is easily worn, which reduces the service life of the disc knife. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and proposes an electric scissors, which solves the technical problem of how to make the electric scissors have low noise and long service life.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an electric scissors, comprising a chassis, a blade and a frame, characterized in that the frame comprises a horizontal plate, a vertical plate and a mounting plate, the chassis has a long strip-shaped through hole, the horizontal plate is fixedly connected to the bottom of the chassis, the bottom of the vertical plate passes through the through hole and is fixedly connected to the horizontal plate, the mounting plate is fixedly connected to the upper part of the vertical plate, and there is a certain distance between the mounting plate and the chassis, the blade is arranged on the mounting plate, and the vertical plate is located directly behind the blade along the front-rear direction of the electric scissors.

[0007] When working, the blade rotates to cut the cloth, and the cloth is separated to the left and right sides of the blade. Since the horizontal plate is located at the bottom of the chassis, and the mounting plate is located above the chassis and has a certain distance from the chassis, the horizontal plate and the mounting plate will not contact the cloth. At the same time, the vertical plate is located directly behind the blade along the front and back direction of the electric scissors. At this time, the cloth is completely opened to the left and right sides of the blade and will not contact the cloth, so that the cloth will not contact the frame and will not be entangled, that is, there is no need to install an elastic sheet, that is, there will be no elastic sheet rubbing the blade, so that the electric scissors have low noise and long service life. The through hole is set for the vertical plate to pass through, so that the frame and the chassis are more compact.

[0008] In the above-mentioned electric scissors, the thickness of the vertical plate is slightly greater than the thickness of the blade. This structure ensures that the vertical plate has sufficient strength and does not get tangled with the cloth, ensuring that the cloth can be separated after cutting; slightly greater, for example, the thickness of the vertical plate is 1mm or 2mm greater than the thickness of the blade.

[0009] In the above-mentioned electric scissors, the lower part of the front end surface of the vertical plate has an arc-shaped arc surface, which is arranged along the edge of the blade, with a certain distance between the arc surface and the blade, and the arc surface is located directly below the blade. This structure enables the frame to have the best support effect and makes the electric scissors compact.

[0010] In the above-mentioned electric scissors, the bottom of the chassis has a mounting frame, the horizontal plate is embedded in the mounting frame, and the frame is fixedly connected to the chassis by fasteners that pass through the chassis and are inserted into the horizontal plate, and the fasteners are located below the upper surface of the chassis. This structure allows the horizontal plate to be embedded in the chassis, which is compact, increases the contact area between the frame and the chassis, increases the connection strength of the frame, and improves the stability of the electric scissors; the fasteners are located below the upper surface of the chassis, so that the fasteners will not interfere with the movement of the cloth, and the fasteners are installed from top to bottom, making the installation of the fasteners convenient.

[0011] In the above electric scissors, the horizontal plate and the vertical plate are an integrated structure, the horizontal plate and the vertical plate are T-shaped, and the vertical plate and the mounting plate are fixedly connected by fasteners. The design is reasonable, ensuring the strength of the frame while facilitating the installation of the blade.

[0012] In the above-mentioned electric scissors, a bottom knife is provided in the chassis, and the bottom knife part extends to the top of the chassis, and the bottom knife is attached to the left or right side of the blade along the front-back direction of the electric scissors. This structure enables the bottom knife to better fit the blade, thereby improving the effect of the electric scissors in cutting cloth.

[0013] In the above-mentioned electric scissors, the mounting plate is fixedly connected with an end cover on the left side along the front-back direction of the electric scissors, the end cover is spaced a certain distance from the chassis, the left side of the end cover has a first heat dissipation port, and the front end of the end cover has a second heat dissipation port. This structure enables the electric scissors to have a good heat dissipation effect, and the hot air will not face the operator.

[0014] In the above electric scissors, a handle is fixedly connected to the left side of the rear end of the mounting plate, and a control button for controlling the rotation of the blade is provided on the handle. The operator can operate the control button while holding the handle, which is convenient for operation.

[0015] Compared with the prior art, the electric scissors provided by the utility model have the following advantages:

[0016] 1. The vertical plate of the electric scissors is located directly behind the blade along the front-back direction of the electric scissors, so that the entire frame will not come into contact with the cut cloth, that is, there is no need to install an elastic sheet, that is, there will be no elastic sheet rubbing the blade, so that the electric scissors have low noise and long service life.

[0017] 2. The cross plate of the electric scissors is embedded in the chassis, which has a compact structure, increases the contact area between the frame and the chassis, increases the connection strength of the frame, and improves the stability of the electric scissors.
