Description

Technical Field

[0001] The utility model relates to a bobbin of a cloth loom, in particular to a bobbin of a denim loom capable of preventing jumping, and belongs to the technical field of denim production and processing. Background Art

[0002] A loom, also known as a spinning machine, weaving machine, or cotton spinning machine, is a mechanical device used to weave cloth. The earliest looms were floor-mounted looms, also called waist looms, and were powered by human labor. With the advancement of the textile industry, looms have evolved from traditional shuttle looms to newer shuttleless looms. Shuttleless looms, with their high efficiency and high quality, have gained a significant position in modern textile production.

[0003] With the development of my country's social economy, cloth looms are widely used in the textile industry. Most textile threads are usually wound on bobbins. During textile production, the textile threads drive the bobbins to rotate. Since the textile operation is fast, the bobbins rotate at a fast speed. In particular, the yarn of denim is relatively rough, and the bobbins will jump up and down along the bobbin axis, which will increase the possibility of the textile threads being entangled with each other and affect the subsequent weaving work. Utility Model Content

[0004] The purpose of the present utility model is to provide a bobbin for a denim loom that prevents jumping in order to solve the above-mentioned problem. The utility model solves the problem that most textile threads are wound on the bobbin, and the textile threads pull the bobbin to rotate during textile production. Since the textile operation is fast, the speed of the bobbin rotation is also fast. In particular, the yarn of denim is relatively rough, which may cause the bobbin to jump up and down along the bobbin axis.

The limiting assembly is arranged in the sleeve, and the adjusting bolt is connected to the top of the sleeve. The adjusting bolt is movably connected to the limiting assembly.

[0007] The limiting assembly includes multiple arc-shaped sliders, multiple connecting rods and multiple extrusion blocks. The multiple arc-shaped sliders are slidably connected to the inner wall of the bobbin. The two ends of the connecting rods are fixedly connected to the arc-shaped sliders and the extrusion blocks respectively. The extrusion blocks are movably connected in the sleeve.

[0008] Preferably, a circular sliding groove is provided on the inner wall of the wire barrel, and the arc-shaped sliding block is slidably connected in the circular sliding groove.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the utility model discloses a bobbin of a denim loom which is capable of preventing bouncing.

[0023] According to the attached Figure 1-4 As shown, it includes a wire spool 1, an installation unit 2 is inserted into the inner side of the wire spool 1, the installation unit 2 includes a sleeve 22, a limit assembly 23 and an adjusting bolt 24, the outer side of the sleeve 22 is sleeved with the wire spool 1, and the wire spool 1 is rotatably connected to the sleeve 22, the limit assembly 23 is arranged in the sleeve 22, the adjusting bolt 24 is connected to the top of the sleeve 22, and the adjusting bolt 24 is movably connected to the limit assembly 23.

[0024] Specifically disclosed, the limiting assembly 23 includes multiple arc-shaped sliders 231, multiple connecting rods 232 and multiple extrusion blocks 234. The multiple arc-shaped sliders 231 are slidably connected to the inner wall of the bobbin 1, and the two ends of the connecting rod 232 are fixedly connected to the arc-shaped slider 231 and the extrusion block 234 respectively. The extrusion block 234 is movably connected in the sleeve 22. Rotating the adjusting bolt 24 can move the adjusting bolt 24 downward, so that the conical block 241 can squeeze the extrusion block 234 to move in the first slide groove 222, thereby driving the connecting rod 232 to move, and then driving the arc-shaped slider 231 to move.

[0025] It should be noted that a circular groove 11 is provided on the inner wall of the bobbin 1, and the arc-shaped slider 231 is slidably connected in the circular groove 11, clamping and fixing the bobbin 1 on the sleeve 22, so that the bobbin 1 will not move up and down during the rotation process, reducing the possibility of the textile threads being entangled with each other.

[0026] Furthermore, a threaded hole 221 is formed on the top of the sleeve column 22 , and the adjusting bolt 24 is threadedly connected in the threaded hole 221 . The adjusting bolt 24 and the threaded hole 221 are partially threadedly connected.

[0027] Furthermore, a plurality of first sliding grooves 222 are defined inside the sleeve 22 , and the extrusion block 234 is slidably connected in the first sliding grooves 222 .

[0028] Furthermore, second sliding grooves 223 are formed on both sides of the sleeve column 22 , and the arc-shaped sliding blocks 231 are movably disposed in the second sliding grooves 223 .

[0029] The specifically disclosed limiting assembly 23 also includes a telescopic spring 233, one end of the telescopic spring 233 is fixedly connected to the extrusion block 234, and the other end is fixedly connected to one side of the first slide groove 222, and the telescopic spring 233 is arranged on the outside of the connecting rod 232. By arranging the telescopic spring 233, the extrusion block 234 compresses the telescopic spring 233 during the movement. When the bobbin 1 needs to be replaced, the adjusting bolt 24 is rotated in the opposite direction to separate the adjusting bolt 24 from the extrusion block 234. Under the action of the telescopic spring 233, the arc-shaped slider 231 is driven to reset to the second slide groove 223, which is convenient for removing and replacing the bobbin 1, thereby speeding up the replacement speed of the bobbin 1 and improving the weaving efficiency.

[0030] It should be noted that the bottom end of the adjusting bolt 24 is fixedly connected to a conical block 241, which abuts against multiple extrusion blocks 234. The extrusion blocks 234 can move back and forth in the first slide groove 222 through the abutment or separation of the conical block 241 and the extrusion blocks 234.

[0031] Furthermore, the installation unit 2 further includes a bottom plate 21 , the sleeve 22 is fixedly connected to the bottom plate 21 , and the bottom plate 21 is connected to the denim loom.

[0032] Working principle: First, put the bobbin 1 on the sleeve 22, and place the bottom of the bobbin 1 on the base plate 21. Then rotate the adjusting bolt 24 to make the adjusting bolt 24 move downward, driving the conical block 241 to move downward. The conical block 241 is pressed against and connected with multiple extrusion blocks 234, driving the extrusion block 234 to move into the first slide groove 222, driving the connecting rod 232 and the arc-shaped slider 231 to move until the arc-shaped slider 231 is engaged in the circular slide groove 11, completing the installation of the bobbin 1. At this time, the extrusion block 234 is completely moved into the first slide groove 222, and the telescopic spring 233 is in an extruded state.

[0033] When the bobbin 1 needs to be replaced, the adjusting bolt 24 is rotated in the reverse direction, so that the adjusting bolt 24 moves upward, driving the conical block 241 to move upward, so that the conical block 241 is separated from the multiple extrusion blocks 234. Under the action of the telescopic spring 233, the extrusion block 234 moves in the reverse direction to the original position in the first slide groove 222, driving the arc slider 231 to return to the second slide groove 223, and the bobbin 1 is removed from the sleeve 22 to complete the replacement.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
