Description

Cutting device equipped with a rotating cutter mounted by magnetic force

[0001] The present invention relates to a cutting device having a magnetically mounted rotary cutter, and more particularly, to a cutting device having a magnetically mounted rotary cutter, which enables the rotary cutter to be easily mounted magnetically on the rotational axis of a driving motor, while the rotary cutter is mounted eccentrically on the rotational axis of the driving motor to extend the cutting length, and improves cutting efficiency by allowing the rotary cutter to slide laterally when it rotates and intersects a fixed cutter.

[0002] Electric cutting devices are used for a variety of purposes in industrial settings.

[0003] Electric cutting devices are classified into stationary and portable types depending on whether they are portable or not.

[0004] These electric cutting devices cut using a rotary cutter that is rotated by a drive motor.

[0005] In conventional electric cutting devices, a rotary cutter is fixed to the rotating shaft of the driving motor with bolts and nuts.

[0006] Rotary cutters can become damaged when cutting hard materials or through repeated use over long periods of time.

[0007] When the rotary cutter is damaged and needs to be replaced, there was a problem that it took a lot of time to replace it because the bolts and nuts had to be loosened to remove the rotary cutter.

[0008] Therefore, there is an urgent need to develop an electric cutting device that is easy to remove when the rotary cutter is damaged.

[0009] The present invention has been proposed to solve the above problems, and aims to facilitate the installation and removal of a rotary cutter.

[0010] In addition, the present invention aims to extend the cutting length of a rotary cutter.

[0011] In addition, the present invention aims to increase the cutting efficiency of a rotary cutter.

[0012] The present invention comprises a frame having a plurality of supports formed at a predetermined interval and a body portion connecting the upper portions of the supports;

[0013] A cutting target support member that is connected to the front side of the above body part and supports the cutting target;

[0014] A driving motor that is arranged adjacent to the cutting target support and is coupled to the body part and provides cutting power;

[0015] A rotary cutter coupled to a rotary shaft located at the bottom of the above driving motor; and,

[0016] A cutting device is provided, characterized in that it includes a controller that controls the operation of the driving motor.

[0017] In addition, the rotary cutter of the present invention is characterized in that it is mounted on a rotary shaft by magnetic force.

[0018] In addition, the present invention has an insertion groove formed at the end of the rotating shaft formed of iron,

[0019] A magnet is attached to the bottom surface of the above insertion groove,

[0020] The above rotary cutter is formed in a plate shape, and a protrusion formed of iron that fits into the insertion groove is formed on the upper surface.

[0021] The above rotary cutter is characterized in that it can be easily inserted and removed into the insertion groove by the magnetic force of the magnet.

[0022] In addition, the protrusion of the rotary cutter of the present invention is characterized in that it is eccentric from the center of the upper surface and coupled to the rotary axis.

[0023] In addition, the insertion groove of the present invention has one side open in the radial direction of the rotation axis and a slot formed on the other side,

[0024] The protrusion is formed at both ends of the projection in a longitudinal direction, and the edge of the protrusion is formed in an arc shape corresponding to the rotational direction of the rotary cutter, so that when the rotary cutter rotates, the protrusion interferes with the frame and the rotary cutter slides along the insertion groove.

[0025] In addition, the present invention comprises a deformation plate disposed at the lower portion of the cutting target support, the two ends of which are connected to the support at a predetermined distance;

[0026] It further includes a spring that is coupled to the lower part of the deformation plate and supports the deformation plate;

[0027] When the above rotary cutter cuts the cutting target, the rotary cutter penetrates into the inside of the cutting target, and when the deformation plate receives a downward load from the cutting target, it is deformed downward, thereby reducing the vertical resistance applied to the rotary cutter.

[0028] In addition, the rotary cutter of the present invention has a blade formed on one side that is thinner than the body,

[0029] A fixed cutter further includes a blade having a thinner thickness than the body of the fixed cutter formed on one side and a fixed cutter connected to the frame with a hinge having a built-in torsion spring on the other side;

[0030] It is characterized in that the cutting target is cut as the blade of the above rotary cutter moves to the upper part of the blade of the above fixed cutter and intersects with it.

[0031] In addition, the present invention includes a detection sensor disposed at the lower portion of the spring to detect the elastic force transmitted by the spring and transmit it to the controller;

[0032] The above controller is characterized in that it stops the rotation of the driving motor when receiving force measurement data measured by the detection sensor.

[0033] In addition, the cutting target support of the present invention is characterized in that four plates are arranged vertically, the lower part of the plates is connected to the frame by a hinge having a built-in torsion spring, and a roller is connected to the inside of the plates.

[0034] In addition, the present invention further includes a discharge rod coupled to the lower portion of the rotary cutter;

[0035] The above discharge bar is characterized in that it discharges the cutting target cut by the above rotary cutter in the direction of rotation.

[0036] The cutting device according to the present invention has the effect of making it easy to mount and dismount the rotary cutter.

[0037] Additionally, the present invention has the effect of extending the cutting length of the rotary cutter.

[0038] In addition, the present invention has the effect of increasing the cutting efficiency of a rotary cutter.

[0050] FIG. 1 is a perspective view of a cutting device (1000) according to a first embodiment of the present invention, FIG. 2 is an exploded view of a cutting device (1000) according to a first embodiment of the present invention, FIG. 3 is a drawing explaining a situation in which a cutting target is cut by a cutting device (1000) according to a first embodiment of the present invention, and FIG. 4 is a side view when a cutting device (1000) according to a first embodiment of the present invention cuts a cutting target.

[0051] A cutting device (1000) according to a first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

[0052] Although Fig. 1 shows cutting fish, the cutting target is not limited to this.

[0053] A cutting device (1000) according to the present invention includes a frame (100), a cutting target support (200), a driving motor (300), a rotary cutter (400), and a controller (not shown in the drawing).

[0054] The frame (100) is provided with a plurality of supports (110) formed at a predetermined interval and a body part (130) connecting the upper portions of the supports (110).

[0055] The body (130) is raised from the ground to a predetermined height by a support (110). This is to enable the rotary cutter (400) described later to rotate smoothly without interference with the ground.

[0056] The cutting target support (200) is a configuration for supporting the cutting target and is connected to the front side of the body part (130).

[0057] In the present invention, in order to smoothly insert the cutting target into the cutting target support (200), it was manufactured so that it can be opened outward as shown in the enlarged view of Fig. 1.

[0058] To this end, the cutting target support (200) is formed by four plates (210) arranged vertically, and the lower part of the plates (210) is connected to the frame (100) by a hinge (230) having a built-in torsion spring.

[0059] In addition, a roller (250) is combined on the inside of the plate (210) to reduce friction with the cutting target, thereby allowing the cutting target to be easily inserted.

[0060] The driving motor (300) is placed adjacent to the cutting target support (200) and is coupled to the body part (130) to provide cutting power.

[0061] In Fig. 2, the member coupled to the rear of the driving motor (300) is configured to stably couple the driving motor (300) to the frame (100).

[0062] The rotary cutter (400) is coupled to a rotary shaft (310) located at the bottom of the driving motor (300).

[0063] In the present invention, in order to facilitate the attachment and detachment of the rotary cutter (400), it is coupled to the rotary shaft (310) by magnetic force.

[0064] The detachable structure of the rotary cutter (400) is described in detail.

[0065] An insertion groove (311) is formed at the end of the rotation shaft (310) formed of iron, and a magnet (313) is coupled to the bottom surface of the insertion groove (311).

[0066] The rotary cutter (400) is formed in the shape of a plate (210), and a protrusion (410) made of iron that fits into the insertion groove (311) is formed on the upper surface.

[0067] Accordingly, the rotary cutter (400) can be easily installed and removed into the insertion groove (311) of the rotary shaft (310) by the magnetic force of the magnet (313), thereby shortening the replacement time of the rotary cutter (400).

[0068] The material of the rotary shaft (310) and the rotary cutter (400) is not limited to iron and can be any material that can be attached to the magnet (313).

[0069] Meanwhile, there are often cases where a cutting target with a large diameter needs to be cut.

[0070] To this end, in the present invention, the protrusion (410) of the rotary cutter (400) is coupled to the rotary shaft (310) eccentrically from the center of the upper surface to extend the cutting length.

[0071] As a result, the effect of extending the cutting length in the rotary cutter (400) of unit weight is obtained.

[0072] Meanwhile, in the present invention, the rotary cutter (400) is rotated and slides laterally, thereby making it easier to cut the cutting target.

[0073] This is based on the idea that when a user cuts an object placed on a cutting board with a knife, the knife is moved diagonally rather than vertically downward.

[0074] Referring to FIGS. 2 and 3, the insertion groove (311) has one side open in the radial direction of the rotation axis (310) and a slot (312) formed on the other side.

[0075] At both ends of the protrusion (410), a projection (411) extending in the longitudinal direction is formed, and the edge of the projection (411) is formed in an arc shape corresponding to the rotational direction of the rotary cutter (400).

[0076] The rotary cutter (400) formed with this structure slides along the insertion groove (311) when the protrusion (411) interferes with the frame (100) while rotating.

[0077] Meanwhile, a discharge rod (430) is attached to the lower part of the rotary cutter (400).

[0078] The discharge rod (430) discharges the cutting target cut by the above rotary cutter (400) in the direction of rotation to enable continuous cutting work.

[0079] If the cut cutting target is not discharged smoothly, the rotary cutter (400) experiences resistance in subsequent cutting, making it impossible to perform continuous work.

[0080] In addition, a deformation plate (500) and a spring (600) may be provided to reduce the vertical resistance of the rotary cutter (400) during cutting.

[0081] Referring to FIG. 4, the deformation plate (500) is placed at the bottom of the cutting target support (200), and both ends of the deformation plate (500) are connected to a support (110) spaced apart at a predetermined interval.

[0082] A spring (600) is coupled to the lower part of the deformation plate (500) to support the deformation plate (500).

[0083] When the rotary cutter (400) cuts the cutting target, the rotary cutter (400) penetrates into the cutting target and the deformation plate (500) receives a downward load due to the cutting target, so the deformation plate (500) is deformed downward, thereby reducing the vertical resistance applied to the rotary cutter (400).

[0084] FIG. 5 is an exploded view of a cutting device (1000) according to a second embodiment of the present invention, FIG. 6 is a drawing explaining a situation in which a cutting target is cut by a cutting device (1000) according to a second embodiment of the present invention, and FIG. 7 is a side view when a cutting device (1000) according to a second embodiment of the present invention cuts a cutting target.

[0085] This is explained with reference to Figures 5 to 7.

[0086] In explaining the second embodiment of the present invention, the differences from the first embodiment will be mainly explained.

[0087] In the second embodiment, a fixed cutter (700) is provided together with a rotary cutter (400), and cutting is performed in the same manner as cutting with scissors.

[0088] Like the rotary cutter (400), the fixed cutter (700) has a blade formed on one side that is thinner than the body, and the other side is connected to the frame (100) by a hinge (710) with a built-in torsion spring.

[0089] The cutting target is cut as the blade of the rotary cutter (400) moves to the upper part of the blade of the fixed cutter (700) and intersects with it.

[0090] In this way, since cutting is performed by intersecting the rotary cutter (400) and the fixed cutter (700), the cutting surface is cut more smoothly than when cutting is performed only with the rotary cutter (400).

[0091] And the other side of the fixed cutter (700) is connected to a hinge (710) having a built-in torsion spring so that the rotary cutter (400) can rotate with less resistance in the vertical direction when the rotary cutter (400) moves to the upper part of the fixed cutter (700) and intersects with it.

[0092] In the second embodiment, the rotation of the rotation axis (310) is stopped after cutting is performed.

[0093] This is for tasks such as discharging the cut cutting object individually after cutting or causing another projectile to get caught in the cutting object.

[0094] For this purpose, a detection sensor (800) is provided.

[0095] The detection sensor (800) is arranged at the bottom of the spring (600) and is configured to detect the elastic force transmitted by the spring (600) and transmit it to the controller.

[0096] When the controller receives force measurement data measured by the detection sensor (800), it stops the rotation of the driving motor (300).

[0097] And, the rotary cutter (400) of the second embodiment is not equipped with a discharge rod (430).

[0098] The present invention relates to a cutting device (1000) equipped with a magnetically mounted rotary cutter (400), and more specifically, to a cutting device (1000) equipped with a magnetically mounted rotary cutter (400), which enables the rotary cutter (400) to be easily mounted magnetically on a rotary shaft (310) of a driving motor (300), and at the same time, the rotary cutter (400) is mounted eccentrically on the rotary shaft (310) of the driving motor (300) to extend the cutting length, and at the same time, improves cutting efficiency by allowing the rotary cutter (400) to slide laterally when it rotates and intersects a fixed cutter (700).

[0099]

[0100] Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by those skilled in the art without departing from the spirit or scope of the present invention as claimed in the claims. Furthermore, such modified embodiments should not be understood individually from the technical idea or prospect of the present invention.
