Description

Technical Field

[0001] The utility model relates to the technical field of leather roller processing, in particular to a leather roller clamping device. Background Art

[0002] The leather roller is one of the main parts of the drafting device of the spinning machine. The middle of the warp and weft spinning machine leather roller is a metal rod, and the two ends are leather roller parts. The leather roller will be continuously worn during use, so it is necessary to polish the leather roller after a period of use to ensure the normal use of the leather roller.

[0003] Currently, during the grinding process of the leather roller, two push rods are used to hold the two ends of the metal rod on the leather roller against each other, and then the leather roller is ground close to the grinding roller. However, during the grinding process, this method is likely to cause the metal rod on the leather roller to separate from the two push rods due to the inconsistency between the force and clamping force applied to the leather roller during grinding, and the grinding of the leather roller is stopped. Moreover, due to the high-speed rotation of the grinding roller, the leather roller is subjected to a large force at this time. When the metal rod separates from the two push rods, the leather roller will be thrown out with a large force, which can easily cause injury to the operator. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 4 A leather roller clamping device includes an operating table 1 and a leather roller body 10. Further, the leather roller body 10 is composed of a metal rod and two leather roller parts, which is a prior art.

[0023] A grinding mechanism is used to grind the surface of the leather roller body 10. The grinding mechanism includes two third plates 15 fixedly connected to the upper end of the operating table 1. A grinding roller 16 is rotatably connected between the side walls of the two third plates 15 through a rotating shaft. A second motor 17 is fixedly connected to the side wall of one of the third plates 15. The movable end of the second motor 17 is fixedly connected to one end of the rotating shaft, so that the high-speed rotating grinding roller 16 can grind the adjacent end of the leather roller body 10.

[0024] The clamping mechanism includes two first plates 2 fixedly connected to the upper end of the operating table 1, a rectangular block 4 is rotatably connected between the two first plates 2 through a first rod 3, two second plates 5 are fixedly connected to the upper end of the rectangular block 4, the two second plates 5 are tilted toward the grinding mechanism, a first arc groove 6 is provided on the side wall of the second plate 5 close to the grinding mechanism, a supporting plate 8 is rotatably connected between the side walls of the two second plates 5 through a second rod 7, a second arc groove 9 is provided on the upper end of the supporting plate 8, and the leather roller body 10 is located in the second arc groove 9, one of the side walls of the second plate 5 is fixedly connected to a first motor 11, and the movable end of the first motor 11 is fixedly connected to one end of the second rod 7.

[0025] The first motor 11 is a self-locking motor. When the roller body 10 is clamped, the initial position of the carrier plate 8 is as follows: Figure 3 As shown, the metal rod on the roller body 10 can be placed in the second arc groove 9, and then the first motor 11 is driven to rotate counterclockwise, and the second rod 7 drives the roller body 10 to rotate counterclockwise through the supporting plate 8, so that the side wall of the metal rod on the roller body 10 is against the inner wall of the first arc groove 6, and then under the action of the supporting plate 8 and the two second plates 5, the metal rod on the roller body 10 is clamped, and the roller body 10 is clamped. In this way, when the roller body 10 is close to the grinding roller 16, the roller body 10 will not separate from the supporting plate 8 and the two second plates 5, resulting in failure of grinding of the roller body 10 or even injury to the staff.

[0026] One end of the first rod 3 passes through one of the side walls of the first plate 2 and is fixedly connected to an operating disk 12. A hand lever 13 is fixedly connected to the side wall of the operating disk 12, which can drive the clamping mechanism to rotate toward the grinding roller 16 to grind the roller body 10.

[0027] The first rod 3 is located between the first plate 2 and the operating panel 12 and is sleeved with a torsion spring 14 . One end of the torsion spring 14 is fixedly connected to the side wall of the first plate 2 adjacent to it, and the other end of the torsion spring 14 is fixedly connected to the side wall of the operating panel 12 .

[0028] like Figure 1 and Figure 2 As shown, when the staff drives the operating disk 12 to rotate clockwise through the hand lever 13, so that the first rod 3 drives the rectangular block 4 to rotate clockwise close to the grinding roller 16, elastic potential energy will be stored on the torsion spring 14 at this time. After the grinding roller 16 grinds the leather roller body 10, the staff releases the hand lever 13, and the elastic potential energy will be released on the torsion spring 14, so that the first rod 3 drives the rectangular block 4 to rotate counterclockwise to its original position, and the position stability of the rectangular block 4 can also be ensured.

[0029] Before grinding the roller body 10, first drive the first motor 11 to rotate clockwise, and the second rod 7 drives the supporting plate 8 to rotate downward to the initial position (such as Figure 3 As shown, the metal rod on the roller body 10 is then placed in the second arc-shaped groove 9, and then the first motor 11 is driven to rotate counterclockwise. The second rod 7 drives the roller body 10 to rotate counterclockwise through the supporting plate 8, so that the side wall of the metal rod on the roller body 10 abuts against the inner wall of the first arc-shaped groove 6. Then, under the action of the supporting plate 8 and the two second plates 5, the metal rod on the roller body 10 is clamped, and the roller body 10 is clamped;

[0030] Then the second motor 17 is driven to rotate, driving the grinding roller 16 to rotate at high speed;

[0031] Then the staff drives the operating disk 12 to rotate clockwise through the hand lever 13, so that the first lever 3 drives the rectangular block 4 to rotate clockwise close to the grinding roller 16, and drives the roller body 10 close to the grinding roller 16, and grinds the two roller parts on the roller body 10;

[0032] At this time, elastic potential energy will be stored on the torsion spring 14. After the grinding roller 16 grinds the leather roller body 10, the staff will release the hand lever 13, and the elastic potential energy will be released on the torsion spring 14, so that the first rod 3 drives the rectangular block 4 to rotate counterclockwise to its original position, and the position stability of the rectangular block 4 can be ensured. Then repeat the above steps to grind the subsequent leather roller body 10.

[0033] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
