Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blade sharpener which can be used not only as a wet type sharpener but also as a dry type sharpener, and which can be switched very easily.

[0002]

[Conventional branch surgery]

 As conventional blade sharpeners, both wet type so-called water sharpeners that use water and dry type sharpeners that do not use water have been found.

However, since the wet type blade sharpener uses water, a method in which a disk-shaped grindstone rotates in a horizontal direction at a low speed was often used, and this was changed to a dry type that does not use water. Even if it was diverted and rotated at a high speed, the sharpening of the blade was uneven due to the contact surface between the grindstone and the blade, and perfect polishing could not be performed.

Therefore, conventionally, in order to be used as both a wet type and a dry type blade sharpener, both blades for wet and dry are equipped, and a blade equipped with a rotation mechanism having a rotation speed suitable for each is provided. Although a sharpening machine was found, the size of the entire device was increased, and the structure was complicated and inevitably expensive.

[0005]

[Problems to be solved by the device]

 The problem to be solved is that the conventional sharpener that can be used for both wet type and dry type is not only large in size and complicated in structure, but also expensive in product. is there.

[0006]

[Means for Solving the Problems]

 The present invention includes a rotating mechanism such as a motor mounted on the main body, a pulley that is rotated and transmitted from this rotating mechanism to rotate in the vertical direction, and a large and small gear that is fixed to the same rotating shaft as the pulley and rotates in synchronization. Either a rotary spindle with a small diameter gear meshed with a gear and a dry type grindstone fixed, or a rotary spindle with a large diameter gear meshed with a small gear and a wet type grindstone fixed. It consists of a pair of bearings, which have the function of replacing one of the bearings, and a water tank formed below the bearings.

[0007]

[Action]

 When used as a dry-type blade sharpener, a rotary main shaft with a dry-type grindstone fixed is spanned over a bearing to support the shaft, and a small gear on the rotary shaft rotates in synchronization with a pulley. Rotate by engaging with.

Next, in the case of using as a wet type blade sharpener, a rotary main shaft to which a wet type grindstone is fixed is spanned over a bearing portion to be pivotally supported, and a large diameter gear of the rotary shaft is rotated in synchronization with a pulley. It is rotated by meshing with a small gear, and water is put in a water tank to immerse the lower part of a wet type grindstone in water. .

The replacement of these grindstones is performed by disassembling the bearing portion, and the number of rotations of the grindstones is set to the number of rotations suitable for each polishing operation.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a main body, and a rotation mechanism 3 such as a motor in which a rotation output unit 2 is located laterally is housed in a portion near the operator side. ing.

Reference numeral 4 denotes a pulley that rotates in a vertical direction by transmitting the rotation of the rotating mechanism 3 by a timing belt 5 and is fixed to a rotating shaft 6 that is supported on one side of a central portion of the main body 1.

Reference numerals 7 and 8 denote large and small gears fixed to the rotary shaft 6 on the inner side of the pulley 4, and rotate in synchronization with the rotation of the pulley 4.

Reference numeral 9 denotes a small-diameter gear meshed with a large gear 7 fixed to the rotary shaft 6, and the small-diameter gear 9 is attached to a rotary main shaft 11 to which a dry type grindstone 10 is fixed.

The rotary main shaft 11 is laid and supported by a pair of bearing parts 12 provided on both sides of the main body 1 and having a replacement function.

Reference numeral 13 denotes a large-diameter gear meshed with a small gear 8 fixed to the rotary shaft 6. The large-diameter gear 13 is attached to a rotary main shaft 15 to which a wet type grindstone 14 is fixed. Similar to the rotary main shaft 11 to which the dry type grindstone 10 is fixed, it is bridged and supported by a pair of bearing parts 12 provided on both sides of the main body 1 and having an exchange function.

Reference numeral 16 denotes a water tank formed between the pair of bearing portions 12 of the main body 1 for containing water when the wet type grindstone 14 is used.

In the embodiment shown in the drawings, the bearing 12 is divided into upper and lower parts and screwed, but the present invention is not limited to this.

[0018]

[Effect of device]

 According to the present invention, as described above, the large and small gears 7 and 8 are fixed to the rotating shaft 6 of the pulley 4 to which the rotation of the rotating mechanism 3 is transmitted, and the small diameter gear 9 meshed with these large and small gears 7 and 8. Since the rotary spindles 11 and 15 having the large-diameter gear 13 and fixed with the dry type grindstone 10 and the wet type grindstone 14 are interchangeably supported, the grindstones 10 and 14 can be replaced as needed. It is easy and the polishing work according to the purpose can be done with one device.

Further, since the dry type grindstone 10 and the wet type grindstone 14 are interchangeable, the entire apparatus can be made compact, and the structure can be simple and can be provided at low cost.
