Description

Technical Field

[0001] The utility model relates to the technical field of ferrite cutting, in particular to a ferrite cutter. Background Art

[0002] The demand for ferrite cutting usually comes from the use of rubber magnets, which are usually in rolls or strips. It is a special material that combines the elasticity of rubber and the magnetism of magnets. It can be cut, bent and processed as needed to meet the needs of different shapes and sizes. It is widely used in home life, teaching aids and industrial fields. In addition to mass-produced goods, there are usually customized sizes. Due to the high cost of production equipment and mold manufacturing, manual cutting meets profit needs, but since the cut magnets will still automatically adsorb together or adsorb on the tool, the disassembly step is added. Utility Model Content

[0003] The utility model provides a ferrite cutter, which aims to separate the cut ferrite and reduce the disassembly steps.

[0004] The above purpose is achieved through the following technical solutions:

The diameter of the anti-slip sleeve is not less than the maximum diameter of the straight rod. When the knife holder is subjected to a longitudinal external force, it can move longitudinally on the anti-slip sleeve, and the knife holder can maintain a relative position unchanged on the anti-slip sleeve through the friction between the two.

[0007] The non-slip cover is neoprene.

[0008] The upper end surface of the support platform is not higher than the top of the roller.

[0025] A ferrite cutter includes a support frame 1 and two supports, wherein the support frame 1 is used to elevate the supports, and there is a distance between the two supports. Specifically:

[0026] For example, the support device located on the left side includes a support platform 4, the right end of the support platform 4 is rotatably connected to a roller 5, the front end of the roller 5 is rotatably connected to a transmission wheel 6, the transmission wheel 6 can be a friction wheel or a gear, the support device is arranged in a mirror-symmetrical manner on the left and right sides, the two support platforms 4 are fixedly connected to the upper end of the support frame 1, the support frame 1 is fixedly connected to two straight rods 2, the two straight rods 2 are respectively located on the front and rear sides of the support device, a cutter 7 is arranged between the two support platforms 4, the cutter 7 can pass between the two support platforms 4 when moving longitudinally, the front and rear ends of the cutter 7 are respectively fixedly connected to a knife seat 8, the two knife seats 8 are respectively inserted into the two straight rods 2, so that the knife seats 8 can be longitudinally moved on the corresponding straight rods 2 Sliding, a transmission member 9 is fixedly connected to the knife seat 8 on the front side. Preferably, the transmission member 9 is an inverted mountain shape. When the transmission wheel 6 is a friction wheel, the left part of the transmission member 9 is frictionally transmitted with the left end of the transmission wheel 6 on the left side. Therefore, when the transmission member 9 descends, it can drive the transmission wheel 6 on the left side to rotate counterclockwise. Similarly, the right part of the transmission member 9 is frictionally transmitted with the right end of the transmission wheel 6 on the right side. The transmission member 9 can drive the transmission wheel 6 on the right side to rotate clockwise, so that the transmission wheel 6 on the left side drives the roller 5 on the left side to rotate counterclockwise, and the transmission wheel 6 on the right side drives the roller 5 on the right side to rotate clockwise.

[0027] Furthermore, a track member 10 is fixedly connected to the middle of the upper end of the cutter 7, and the left and right end surfaces of the track member 10 are both inclined. The track member 10 is generally a triangle with the tip facing downward. The left end surface of the track member 10 extends from bottom to top to the left, and the right end surface of the track member 10 extends from bottom to top to the right.

[0028] A necked section is provided at the top of the straight rod 2 to form a shoulder, and an anti-slip sleeve 3 is fixedly connected to the reduced diameter section of the straight rod 2. The diameter of the anti-slip sleeve 3 is not less than the maximum diameter of the straight rod 2. When the knife seat 8 is subjected to a longitudinal external force, it can move longitudinally on the anti-slip sleeve 3, and the knife seat 8 can maintain a relative position unchanged on the anti-slip sleeve 3 through the friction between the two.

[0029] During operation, a flexible ferrite, such as a rubber magnet, is placed between two support platforms 4 at a position to be cut. The flexible ferrite is placed on the two support platforms 4, and the cutter 7 is operated to descend to cut the flexible ferrite. At this time, the two rollers 5 also keep rotating, and the track member 10 descends with the cutter 7. The track member 10 applies a downward force to the flexible ferrite, increasing the friction between the flexible ferrite and the roller 5, so that the roller 5 on the left drives the left part of the cutting position of the flexible ferrite to move to the left, and the roller 5 on the right drives the left part of the cutting position of the flexible ferrite to move to the right, so as to avoid the flexible ferrite after cutting from being still adsorbed together. The track member 10 descends and is also inserted into the cutting position to separate the flexible ferrite divided into two, thereby realizing automatic separation after cutting.

[0030] Among them, preferably, the anti-slip sleeve 3 is made of chloroprene rubber to improve wear resistance, the upper end surface of the support platform 4 is not higher than the top of the roller 5, so that the flexible ferrite can be supported while the cutting position remains in contact with the roller 5, and the upper end surface of the support platform 4 is made of glass or acrylic material to make the surface as smooth as possible to reduce the friction between the flexible ferrite.

[0031] Preferably, the outer surface of the roller 5 is provided with anti-skid patterns, and the extending direction of the anti-skid patterns is parallel to the axis of the roller 5, so as to increase the friction between the roller 5 and the flexible ferrite.

[0032] The middle of the blade at the bottom of the cutter 7 is arched upward, so that the bottom of the cutter 7 forms two inclined blades, which contact the left and right edges of the upper end of the flexible ferrite at the same time, so that the flexible ferrite is centered during the cutting process.
