Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a high-precision fancy spinning bottom roller with a slotted structure. Background Art

[0002] The field of textile equipment technology is a category that covers various mechanical devices used in textile production and their related technologies. It includes equipment involved in the entire process from fiber raw material processing to final fabric formation, such as cotton cleaning machines, carding machines, drawing machines, roving machines, spinning machines, winding machines and other machines. In textile equipment, rollers are very important components. Rollers are generally cylindrical rollers and play a key role in the spinning process. The front bottom roller is mainly used in spinning equipment such as spinning machines. With the improvement of living standards, the market demand for various fancy yarns is increasing, and the market prospects are relatively broad.

[0003] Traditional fancy yarns are mainly single-core fancy yarns. The principle is that the roving is drafted by the rear and middle rollers, and the single-core wire is input into the core roller, and at the same time enters the front roller for drafting, and is twisted through the hollow spindle to the output roller for winding to achieve the purpose of yarn formation. However, for double-core fancy yarns that require higher strength, traditional fancy spinning twisting machines cannot solve the problem of orderly feeding and winding of the double-core wires. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a high-precision fancy spinning bottom roller with a slotted structure, which solves the problem that traditional fancy spinning twisting machines cannot solve the problem of orderly feeding and winding of double-core wires.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-precision fancy spinning bottom roller with a slotted structure, comprising a front bottom roller roller, the outer wall of the front bottom roller roller is evenly and fixedly connected with guide teeth, the outer wall of the guide teeth is symmetrically provided with grooves, and the sides where the guide teeth are connected to the grooves are provided with fourth arc chamfers, a connecting structure is provided in the middle of one end of the front bottom roller roller, and a first connecting column is fixedly connected in the middle of the other end of the front bottom roller roller, and the tooth shape, tooth top and tooth root of the guide teeth are all arc-shaped.

[0006] Preferably, the connecting structure includes a second connecting column, one end of the second connecting column is fixedly connected to the middle of one end of the front bottom roller, and the middle of the other end of the second connecting column is fixedly connected to a connecting head.

[0007] Preferably, the other end of the second connecting column is provided with a fifth arc chamfer.

[0008] Preferably, a through hole is provided inside the first connecting column, and the groove is a straight groove.

[0009] Preferably, a through groove is provided inside one end of the front bottom roller, and the interior of the through groove is connected with the interior of the through hole.

[0010] Preferably, a third arc chamfer is provided at one end of the first connecting column away from the front bottom roller.

[0011] Preferably, both ends of the front bottom roller are provided with a second arc chamfer.

[0012] Preferably, both ends of the guide tooth are provided with a first arc chamfer.

[0013] Working principle: through the setting of the connector and the second connecting column, and through the through groove inside the front lower roller roller connected with the through hole inside the first connecting column, it is convenient to connect the front lower roller roller with other equipment components, and the coarse yarn is transported and stretched by the front lower roller roller during the spinning process, and the guide teeth evenly fixedly connected to its outer wall play a guiding and controlling role in the transmission of the coarse yarn. The design of the groove straight groove makes the spun yarn more stable during the movement, and enables the double core wire to be input into the hollow spindle in an orderly manner. At the same time, the setting of the fourth arc chamfer optimizes the transition of the fiber between the guide tooth and the groove, and the tooth shape, tooth top and tooth root of the guide tooth are all arc-shaped. The arc-shaped tooth shape can make the fiber receive more uniform pressure when passing through the guide tooth, reducing fiber damage and breakage. The arc design of the tooth top can effectively prevent the core wire from being entangled on the tooth top during movement, and the arc of the tooth root is conducive to the smooth transition of the fiber. When the core wire enters the hollow spindle, the tooth top will not entangle the core wire.

[0014] The present invention provides a high-precision fancy spinning bottom roller with a slotted structure. It has the following beneficial effects:

[0015] 1. The tooth shape, tooth top and tooth root of the guide teeth of the present invention are all arc-shaped, so that the fibers are subjected to uniform pressure when passing through, reducing fiber damage and breakage, and the straight groove design of the groove is conducive to the smooth movement of the fiber, which is beneficial to ensuring the quality uniformity and strength of the yarn. At the same time, its symmetrical design enables the double-core wire to be fed into the hollow spindle in an orderly manner, and the fourth arc chamfer optimizes the transition of the fiber between the guide teeth and the groove, preventing it from being hooked or stuck at the connection, ensuring the continuity and stability of the entire spinning process, and solving the problem of orderly feeding and winding of the double-core wire that cannot be solved by traditional fancy spinning twisting machines.

[0016] 2. The chamfer design of each component of the present invention optimizes the transition of the fiber on the roller, prevents the fiber from hooking or getting stuck, and ensures the continuity and stability of the spinning process. The slotted structure may be more suitable for the spinning of fine and ultra-fine fancy yarns, making the yarn pattern more precise, stable and reliable. At the same time, it avoids the problems of large consumption of the leather rollers caused by slotting on traditional leather rollers, time-consuming replacement of the leather rollers, and low production efficiency.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a high-precision fancy spinning bottom roller with a slotted structure, comprising a front bottom roller roller 1, the outer wall of the front bottom roller roller 1 is evenly fixedly connected with guide teeth 2, the outer wall of the guide teeth 2 is symmetrically provided with grooves 4, and the sides where the guide teeth 2 are connected to the grooves 4 are provided with fourth arc chamfers 11, a connecting structure is provided in the middle of one end of the front bottom roller roller 1, and a first connecting column 7 is fixedly connected in the middle of the other end of the front bottom roller roller 1, and the tooth shape, tooth top and tooth root of the guide teeth 2 are all arc-shaped; the connecting structure comprises a second connecting column 12, one end of the second connecting column 12 is fixedly connected to the A connector 3 is fixedly connected to the middle part of one end of the front lower roller 1 and the middle part of the other end of the second connecting column 12; a fifth arc chamfer 13 is provided at the other end of the second connecting column 12; a through hole 9 is provided inside the first connecting column 7, and the groove 4 is a straight groove; a through groove 10 is provided inside one end of the front lower roller 1, and the interior of the through groove 10 is connected with the interior of the through hole 9; a third arc chamfer 8 is provided at the end of the first connecting column 7 away from the front lower roller 1; second arc chamfers 6 are provided at both ends of the front lower roller 1; and first arc chamfers 5 are provided at both ends of the guide tooth 2.

[0024] Specifically, the roving is transported and stretched during the spinning process by the front lower roller 1, which is made of high-strength steel to ensure that it can maintain stable performance during long-term high-speed operation without deformation or damage. The guide teeth 2 evenly fixedly connected to its outer wall guide and control the roving during transmission. The straight groove design of the groove 4 makes the roving more stable during movement, reduces the jitter and deviation of the roving, and enables the double-core wire to be input into the hollow spindle in an orderly manner. At the same time, the setting of the fourth arc chamfer 11 optimizes the transition of the fiber between the guide teeth 2 and the groove 4, prevents the fiber from being hooked or stuck at the connection, thereby ensuring the continuity and stability of the entire spinning process, and solves the problem that the traditional fancy spinning twisting machine cannot solve the problem of orderly feeding and winding of the double-core wire.

[0025] The tooth shape, tooth top and tooth root of the guide tooth 2 are all arc-shaped. The arc-shaped tooth shape can make the fiber receive more uniform pressure when passing through the guide tooth 2, reducing the damage and breakage of the fiber. The arc design of the tooth top can effectively prevent the core wire from being entangled on the tooth top during movement, ensuring the smoothness of fiber transmission. The arc of the tooth root is conducive to the smooth transition of the fiber, avoiding the accumulation or jamming of the fiber at the tooth root. When the core wire enters the hollow spindle, the tooth top will not be entangled with the core wire, and the core wire will not shake, thereby not damaging the fiber. The spun yarn movement is more stable, making the yarn quality stable.

[0026] The through slot 10 inside the front bottom roller 1 is connected with the through hole 9 inside the first connecting column 7, which facilitates the connection with other equipment components. For example, the power can be transmitted to the front bottom roller 1 by inserting a transmission shaft into the through hole 9, so that it can rotate at a predetermined speed and direction, thereby realizing accurate drafting of the fiber.

[0027] By setting the connecting head 3 and the second connecting column 12, it is convenient to connect the front bottom roller 1 with other equipment parts. The first arc chamfer 5 is set at both ends of the guide tooth 2, which not only makes the appearance of the guide tooth 2 smoother and more beautiful, but also plays a guiding role when the fiber enters and leaves the guide tooth 2, thereby reducing the friction resistance of the fiber and reducing the risk of fiber damage.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
