Description

Area of ​​the utility model

[0001] The present utility model relates to the field of tool grinding technology, in particular to a novel roller grinder. State of the art

[0002] A roller grinder is a tool used for sharpening knife tools. It sharpens the knife blade through rolling friction, thus making the knife sharper. Compared to conventional manual whetstones or fixed whetstones, roller grinders are typically constructed with cylindrical or segmented grinding wheels to make grinding more efficient and less labor-intensive.

[0003] However, the grinding plate currently installed on the roller grinder rotates with the body. The main grinding mechanism is rotary grinding. Although rotary grinding can grind the tool blade more evenly, rotary grinding generally requires special grinding machine equipment. Its operation is relatively complex and requires a certain level of skill and experience. However, linear grinding is simple. It involves holding the knife in the hand and moving it exclusively along the grindstone. Abandonment of the utility model

That is, unless explicitly stated, each feature is only one example of a series of equivalent or similar features.

[0016] As in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig.5, a novel roller grinder according to the present utility model comprises a body 1, a rotary grinding wheel fastener 17, and a linear grinding wheel fastener 2, wherein both ends of the body 1 protrude to form a fastening portion 18. A fastening hole passing through the body 1 and the fastening portion 18 is provided at the fastening portion 18. One end of the rotary grinding wheel fastener 17 and one end of the linear grinding wheel fastener 2 are respectively provided in the fastening hole on both sides and are fixedly fastened to a cylinder with a bolt 12 and a nut 13. A linear grinding wheel 4 is provided on an outer side of the linear grinding wheel fastener 2.Outside the rotary grinding wheel fastener 17, a first rolling wheel ring 3 is movably provided, which rotates synchronously with the body 1, and on an outer side of the first rolling wheel ring 3, a rotary grinding wheel 16 is provided.

[0017] In this embodiment, an outer end surface of the linear grinding wheel fastener 2 is recessed to form a first positioning groove, and an outer end surface of the first rolling wheel ring 3 is recessed to form a second positioning groove. A magnetic fastening disc 10 is provided in each of the first positioning groove and the second positioning groove, and a magnet 15 is provided on an inner side of each of the magnetic fastening disc 10. The linear grinding wheel 4 is provided in the first positioning groove and is adsorbed by the magnet 15. The rotary grinding wheel 16 is provided in the second positioning groove and is adsorbed by the magnet 15.

[0018] In this embodiment, a first bearing 11 is mounted on the linear grinding wheel fastener 2, and a second rolling wheel ring 8 is mounted on the outer ring of the first bearing 11, a sunken ring groove 9 is provided on an outer ring surface of the first rolling wheel ring 3 and on an outer ring surface of the second rolling wheel ring 8, and a silicone ring 7 is provided in each of the ring groove 9, and a second bearing 14 is mounted between the rotary grinding wheel fastener 17 and the second rolling wheel ring 8.

[0019] In this embodiment, an outer ring surface of the first positioning groove and an outer ring surface of the second positioning groove are each sunken and form a plurality of positioning openings 6, wherein an outer ring of the linear grinding wheel 4 and an outer ring of the rotary grinding wheel 16 each protrude at a position corresponding to the positioning opening 6 and form a positioning section 5, which is each provided inserted in the positioning opening 6.

[0020] The linear grinding wheel 4 and the rotary grinding wheel 16 are adsorbed and fixed by magnets after being inserted into the corresponding first positioning groove and the second positioning groove, while the linear grinding wheel 4 and the rotary grinding wheel 16 can be positioned in the circumferential direction by the plug connection between the positioning opening and the positioning section in order to avoid spontaneous rotation.

[0021] In this embodiment, a diameter of the silicone ring 7 is larger than a diameter of the body 1, so that the silicone ring is in full contact with the table and the rotation of the rotary grinding wheel is thus enabled by friction.

[0022] In this embodiment, the rotary grinding wheel fastener 17 and the linear grinding wheel fastener 2 are each provided with a through hole at one end within the mounting hole, wherein the screw 12 passes through the through hole and the mounting hole and is threadably connected to the nut 13. After removing the magnetic mounting disc, the nut can be unscrewed and the screw removed, so that the rotary grinding wheel fastener 17 and the linear grinding wheel fastener 2 can be removed to the outside to facilitate disassembly and replacement.

[0023] This device must be used with the magnetic tool holder. After the tool is attached to the magnetic tool holder, when the tool is to be ground, the rotary grinding wheel is brought into contact with the blade of the tool and the body is rotated, causing the body to rotate forward. The movement of the body moves the first rolling wheel ring through the friction of the silicone ring, and the first rolling wheel ring moves the rotary grinding wheel, causing the rotary grinding wheel to rotate forward and grind.

[0024] When rotary grinding is not needed, the linear grinding wheel is brought into contact with the tool blade and the body is advanced. When the body rotates forward, only the second roller wheel ring rotates, and the linear grinding wheel does not rotate, as the second roller wheel ring is mounted on the first bearing. Thus, the linear grinding wheel rolls to grind the tool, increasing adaptability.

[0025] The above are only concrete embodiments of the present utility model, but the scope of protection of the present utility model is not limited to them. Any modification or replacement not conceived through creative work should fall within the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be the scope defined in the claims. List of reference symbols
