UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a line wheel which is easy to dismount and simple in structure, and meet the requirement of quick replacement of diamond cutting wire in use.

[0005] The technical solution adopted by the utility model to solve the technical problem is:

[0006] A kind of line wheel convenient to dismount, including line cylinder, center shaft, front cone cover, rear cone cover, the both ends of line cylinder are equipped with annular limit plate, line cylinder inner center line is equipped with the hollow cavity that contains center shaft, the both ends of hollow cavity are connected with front cone cover, rear cone cover respectively, the abutment of center shaft and rear cone cover is integrally formed with limit step, its end is equipped with positioning screw hole, positioning screw hole is connected with fastening screw rod thread, the end of front cone cover is detachably connected with center shaft by fastening screw rod, the outer side of front cone cover is equipped with positioning blind hole.

[0007] In a certain demonstration embodiment, the front cone cover is made of cast iron or other material with high hardness, to meet the requirement that the front cone cover will not deform during the limiting process of inserting the crescent wrench into the positioning blind hole.

[0008] The front cone cover has a limiting groove and a retaining groove at the end away from the spool. The limiting groove contains a buffer pad and a flange ring. The buffer pad is in the shape of a disc. The flange ring has a groove in the middle that matches the end of the central shaft, and its end face has a connecting through hole. The retaining groove contains a retaining block, which is located at the end of the buffer pad and flange ring away from the central shaft to prevent the flange ring from detaching from the limiting groove.

[0009] Preferably, a positioning sleeve is fitted on the central shaft located in the middle of the spool, and the circumferential surface of the positioning sleeve is in contact with the inner surface of the middle part of the spool body.

[0010] The positioning sleeve is connected to the limiting concave surface on the central shaft via a limiting screw.

[0011] The end of the central shaft furthest from the spool is fixed on the mounting base and connected to the servo motor via a coupling.

[0012] In one exemplary embodiment, the mounting base is provided with a locking block, one end of which extends to the top of the rear cone cover and has a locking through hole at the end. The rear cone cover is provided with locking holes at intervals. By inserting a locking rod through the locking through hole and into the locking hole, the rotation of the spool is locked, so that the spool no longer rotates with the rotation of the central shaft.

[0013] During the machining of the wire reel, the spool and the limiting plate are directly integrally molded. Then, the front and rear conical covers are embedded into the spool. The central shaft then passes sequentially through the rear conical cover, the spool, and the front conical cover. Finally, a fastening screw connects to the threaded end of the central shaft and is tightened. The fastening screw is pressed against the flange ring inside the front conical cover. The limiting step on the central shaft limits the rear conical cover, thus working with the front and rear conical covers to center and tighten the spool. When the central shaft rotates, it is supported and rotated by the mounting base, providing stable rotational power to the wire reel.

[0014] When in use, the spool needs to be rotated and locked. This can be done by inserting a locking rod into the locking through hole of the locking block and then further inserting it into the locking hole of the rear cone cover.

[0015] When the spool needs to be disassembled and replaced, simply insert a crescent wrench into the positioning blind hole of the front cone cover to quickly lock the spool, then rotate the fastening screw to separate the front cone cover from the central shaft, and then remove the spool from the rear cone cover.

[0016] The advantages of this easily detachable spool:

[0017] Compared to existing reels, which use a rear cone cover and locking block to lock the rotation of the reel before loosening the fastening screw to disassemble the reel, this application uses a crescent wrench inserted into a positioning blind hole on the outer side of the front cone cover to limit the rotation of the front cone cover and the reel before loosening the fastening screw to disassemble the reel. This not only avoids the shortcomings of existing reel disassembly methods that cause deformation of the locking block, but also works with the locking block to lock the rotation of the reel, reducing wear on the equipment.

[0018] The easily disassembled spool of this application features a front cone cover made of high-hardness materials such as cast iron, which reduces deformation of the positioning blind hole when the front cone cover is locked during spool disassembly. Furthermore, the raw materials are widely available, meeting the needs of large-scale production. Its central shaft adopts a one-piece molded structure, with a limiting step in the middle that limits the rear cone cover. This, combined with the front cone cover, centers and tightens the spool, resulting in a simple structure that provides stable rotational power to the spool. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-7 This application discloses a detachable reel, comprising a spool 4, a central shaft 9, a front conical cover 3, and a rear conical cover 5. The spool 4 has annular limiting plates 41 at both ends, and a hollow cavity 42 accommodating the central shaft 9 is provided along the centerline of the spool 4. The two ends of the hollow cavity 42 are connected to the front conical cover 3 and the rear conical cover 5, respectively. A limiting step 91 is integrally formed at the contact point between the central shaft 9 and the rear conical cover 5, and a positioning screw hole 92 is provided at its end, which is threadedly connected to a fastening screw 1. The front conical cover 3 is detachably connected to the end of the central shaft 9 via the fastening screw 1, and a positioning blind hole 31 is provided on the outer surface of the front conical cover 3.

[0029] The front cone cover 3 is made of a material with high hardness, such as cast iron, so as to meet the requirement that the front cone cover 3 will not deform during the process of limiting the front cone cover 3 by inserting a crescent wrench into the positioning blind hole 31.

[0030] See Figure 4 and 5 The front cone cover 3 is provided with a limiting groove 33 and a retaining groove 32 at the end away from the spool 4. The limiting groove 33 is provided with a buffer pad 13 and a flange ring 2. The buffer pad 13 is in the shape of a circular plate. The flange ring 2 is provided with a groove in the middle that matches the end of the central shaft 9, and its end face is provided with a connecting through hole. The retaining groove 32 is provided with a retaining block 12. The retaining block 12 is located at the end of the buffer pad 13 and the flange ring 2 away from the central shaft 9, and is used to prevent the flange ring 2 from detaching from the limiting groove 33. The outer periphery of the front conical cover 3 facing the end of the spool 4 is provided with a first conical surface, a second conical surface, and a third conical surface that abut against the inner side of the spool 4. The middle part is provided with a through hole that communicates with the limiting groove for holding the central shaft 9. The dimensions of the first conical surface, the second conical surface, and the third conical surface decrease in sequence. The first conical surface facilitates the front conical cover 3 and the rear conical cover 5 to center and tighten the spool. The second conical surface and the third conical surface facilitate the centering of the front conical cover 3 with the central shaft 9 and facilitate the tightening of the end of the central shaft.

[0031] A positioning sleeve 11 is fitted onto the central shaft 9 located in the middle of the spool 4. The circumferential surface of the positioning sleeve 11 is in contact with the inner surface of the spool body in the middle. The positioning sleeve 11 is connected to the limiting concave surface 93 on the central shaft 9 via a limiting screw. The positioning sleeve 11 can better support the middle of the spool 4 and prevent the spool 4 from deforming due to the pulling force of the cutting wire during use.

[0032] The outer periphery of the limiting plate 41 is rounded.

[0033] The end of the central shaft 9 away from the spool 4 is fixed on the mounting base 6 and connected to the servo motor 7 via the coupling 10.

[0034] The mounting base 6 is provided with a locking block 8. One end of the locking block 8 is fixed on the mounting base 6, and the other end extends to the top of the rear cone cover 5. The end of the locking block 8 is provided with a locking through hole 81. The rear cone cover 5 is provided with locking holes 51 at intervals. The locking rod is inserted into the locking hole 51 through the locking through hole 81, thereby locking the rotation of the spool 4 and preventing the spool 4 from rotating with the rotation of the central shaft 9.

[0035] Working principle and usage of this utility model:

[0036] During the machining of the wire reel, the wire spool 4 and the limiting plate 41 are directly integrally molded. Then, the front conical cover 3 and the rear conical cover 5 are embedded into the wire spool 4. The central shaft 9 then passes through the rear conical cover 5, the wire spool 4, and the front conical cover 3 in sequence. Finally, the central shaft 9 is threadedly connected to and secured to the end of the central shaft 9 by a fastening screw 1. The fastening screw 1 is pressed against the flange ring 2 inside the front conical cover 3. The limiting step 91 on the central shaft 9 can limit the rear conical cover 5, thereby working with the front conical cover 3 and the rear conical cover 5 to tighten the wire reel. When the central shaft 9 rotates, it is supported and rotated by the mounting base 6, which can provide stable rotational power for the wire reel.

[0037] When in use, the spool 4 needs to be rotated and locked. A locking rod can be inserted into the locking through hole 81 of the locking block 8, and the locking rod can be further inserted into the locking hole 51 of the rear cone cover 5 to lock the spool 4 so that the spool 4 no longer rotates with the rotation of the central shaft 9.

[0038] When the reel needs to be disassembled and replaced, simply insert a crescent wrench into the positioning blind hole 31 on the outer side of the front cone cover 3 to quickly restrict the rotation of the spool 4 with the central shaft 9. Then rotate the fastening screw 1 to unscrew it from the positioning screw hole 92. Then remove the front cone cover 3 from the central shaft 9. Next, remove the spool 4 and the rear cone cover 5 from the central shaft 9 in sequence to disassemble the spool 4. Then, put the rear cone cover 5, the spool 4, and the front cone cover 3 to be replaced onto the central shaft 9 in sequence to replace it with a new reel.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is used only to illustrate the technical solution of this utility model, and is not intended to limit the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the protection scope of this utility model.
