Description

Technical Field

[0001] The utility model relates to the technical field of textile machines, in particular to a winding mechanism with a pressure roller. Background Art

[0002] In the textile industry, after yarn is coated with sizing, it needs to be rolled into rolls for easy transportation and storage, which requires a winding mechanism. Existing winding mechanisms typically consist of a winding roller and multiple traction rollers. The winding roller rotates under the power of a motor, pulling the yarn around the winding roller in turns, while the yarn drives the multiple traction rollers to rotate. However, because existing winding mechanisms struggle to effectively tension the yarn, the yarn wound around the winding rollers is prone to becoming loose and loose. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a winding mechanism with a pressure roller, which can effectively prevent the yarn from being unwound on the winding roller.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a winding mechanism with a pressure roller, including a frame and a traction roller group, a pressure roller group, and a winding roller group arranged on the frame; the yarn can be wound on the winding roller group after passing through the traction roller group and the pressure roller group in sequence; wherein,

[0005] The pressure roller group includes a pressure driving member, a rotating seat, and a pressure roller; the pressure driving member is installed on the frame to drive the rotating seat to rotate; two pressure rollers are provided, and are symmetrically arranged on the rotating seat with the rotation axis of the rotating seat as the center line; a gap is defined between the two pressure rollers for the yarn to pass through; when the pressure driving member drives the rotating seat to rotate, the two pressure rollers rotate synchronously so that the yarn can be wound onto the outer surfaces of the two pressure rollers.

[0006] The beneficial effects of the winding mechanism of the utility model are:

[0007] During the process of winding the yarn, the rotating seat is driven to rotate by the compression drive member, which can drive the two pressure rollers to rotate synchronously, so that the yarn close to the compression roller group can be wound onto the outer surfaces of the two pressure rollers to extend the traction path of the yarn, and the yarn located between the compression roller group and the winding roller group can be in a taut state, so as to avoid the yarn from being loosened before the yarn is wound onto the winding roller group.

[0008] In addition, if the yarn wound on the winding roller group becomes loose, the winding action of the winding roller group is stopped, and the clamping drive member is driven in reverse so that the rotating seat drives the two pressure rollers to rotate in the opposite direction. At this time, the yarn wound on the winding roller group can be rewound onto the outer surfaces of the two pressure rollers so that the loose yarn part returns to the traction path; and then the winding roller group is restarted to wind the yarn again.

[0009] Specifically, the rotating base includes a first rotating plate and a second rotating plate arranged in parallel. A rotating shaft coaxially connected to the pressing drive member is located at the center of each of the first and second rotating plates. Each of the first and second rotating plates is provided with pressing roller perforations corresponding to the pressing rollers, with the diameters of the pressing roller perforations matching the outer diameters of the corresponding pressing rollers. The coordination of the first and second rotating plates allows the spacing between the two pressing rollers to be defined, thereby ensuring a stable spacing between the two rollers.

[0010] Furthermore, the pressure roller assembly includes a pair of limit plates for limiting the position of the yarn. Each limit plate is mounted on the two pressure rollers and locked to the pressure rollers via a locking member. The limit plates can be used to define the winding position of the yarn on the pressure rollers, and the locking member can be used to lock the position of the limit plates on the pressure rollers.

[0011] Specifically, the locking member includes a matching hoop seat and a clamping strip. Opposite sides of the hoop seat and the clamping strip are each provided with an arcuate groove that matches the shape of the pressure roller. The hoop seat and the clamping strip are locked together by bolts. The detachable connection between the hoop seat and the clamping strip facilitates adjustment of the position of the limit plate on the pressure roller.

[0012] Furthermore, a rubber gasket is provided between the arc groove and the pressure roller to prevent the pressure roller from being damaged when the hoop seat and the clamping strip are locked.

[0013] Specifically, the pulling roller assembly includes a first pulling portion, a second pulling portion, and a third pulling portion, which are arranged in sequence. Each of the first, second, and third pulling portions pulls the yarn in different directions. The pulling direction refers to the direction in which the yarn moves along each pulling portion. By defining different pulling directions for each pulling portion, the yarn pulling path becomes more complex, thereby achieving a certain degree of yarn tensioning.

[0014] Furthermore, the first traction part includes a plurality of first traction rollers, the second traction part includes a plurality of second traction rollers, and the third traction part includes a plurality of third traction rollers, and the outer diameters of the first traction rollers, the second traction rollers, and the third traction rollers are all different.

[0015] Furthermore, the winding roller assembly includes a winding drive member, a synchronous transmission member, and a winding drum installed on the frame, and the winding drive member drives the winding drum to rotate through the synchronous transmission member.

[0016] Furthermore, the synchronous transmission member adopts chain transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0029] Example

[0030] See attached Figure 1-2As shown, the present invention provides a winding mechanism with a pressure roller, comprising a frame 1 and a traction roller group 2, a pressure roller group 3, and a winding roller group 4 arranged on the frame 1. The yarn 5 can be wound onto the winding roller group 4 after passing through the traction roller group 2 and the pressure roller group 3 in sequence. The pressure roller group 3 includes a pressure drive 31, a rotating base 32, and a pressure roller 33. The pressure drive 31 is mounted on the frame 1 to drive the rotating base 32 to rotate. Two pressure rollers 33 are provided and are symmetrically arranged on the rotating base 32 with the rotating axis of the rotating base 32 as the center line. A gap is defined between the two pressure rollers 33 for the yarn 5 to pass through. When the pressure drive drives the rotating base to rotate, the two pressure rollers rotate synchronously, so that the yarn can be wound onto the outer surfaces of the two pressure rollers.

[0031] In the process of winding the yarn, the yarn 5 can be wound onto the winding roller group 4 after passing through the traction roller group 2 and the pressure roller group 3 in sequence. If the yarn 5 becomes loose before it is wound onto the winding roller group 4, the rotating seat 32 is driven to rotate by the pressure driving member 31 (such as Figure 1 The two pressure rollers 33 can rotate synchronously, so that the yarn 5 near the pressure roller group 3 can be wound onto the outer surfaces of the two pressure rollers 33 to tighten the yarn 5 (equivalent to extending the traction path of the yarn). This can prevent the yarn 5 from being loosened before it is wound onto the winding roller group 4.

[0032] When the yarn 5 is wound around the winding roller group 4 and becomes loose, the winding action of the winding roller group 4 is stopped, and the pressing drive member 31 is driven in the reverse direction so that the rotating seat 32 drives the two pressing rollers 33 to rotate in the reverse direction (such as Figure 1 At this time, due to the lack of power source of the winding roller group 4, the yarn 5 wound on the winding roller group 4 can be rewound onto the outer surfaces of the two pressure rollers 33 under the action of the pressure roller group 3, so that the yarn 5 with the loose winding part can be returned to the traction path; and then the winding roller group 4 is restarted to rewind the yarn 5.

[0033] In some embodiments, see Appendix Figure 2-3 As shown, the rotating base 32 includes a first rotating plate 321 and a second rotating plate 322 arranged in parallel. A rotating shaft 323, coaxially connected to the pressing drive 31, is located at the center of each of the first and second rotating plates 321, 322. Furthermore, each of the first and second rotating plates 321, 322 is provided with pressing roller perforations corresponding to the pressing rollers 33. The diameter of each pressing roller perforation matches the outer diameter of the corresponding pressing roller 33. The coordination of the first and second rotating plates 321, 322 allows the spacing between the two pressing rollers 33 to be defined, ensuring stability.

[0034] For further information, see Appendix Figure 3As shown, the pressure roller assembly 3 also includes a pair of limiting plates 34. Each limiting plate 34 is mounted on the two pressure rollers 33 and locked to the pressure rollers 33 via a locking member. The yarn 5 can be wound around the pressure rollers 33 between the pair of limiting plates 34. The limiting plates 34 can define the winding position of the yarn 5 on the pressure rollers 33, and the locking member can lock the limiting plates 34 on the pressure rollers 33 to ensure the stability of the limiting plates 34.

[0035] Furthermore, the locking member includes a cooperating hoop seat 351 and a clamping strip 352. Opposing sides of the hoop seat 351 and the clamping strip 352 are each provided with an arcuate groove that matches the shape of the pressure roller 33. The hoop seat 351 and the clamping strip 352 are locked together by bolts. The use of bolts to lock the hoop seat 351 and the clamping strip 352 allows for quick disconnection and detachment of the hoop seat 351 and the clamping strip 352, facilitating adjustment of the position of the limit plate 34 on the pressure roller 33 as needed.

[0036] Furthermore, a rubber gasket is sandwiched between the arc groove and the pressure roller 33 to prevent damage to the pressure roller 33 when the clamp seat 351 and the clamp strip 352 are locked.

[0037] In some embodiments, see Appendix Figure 4 As shown, the pulling roller assembly 2 includes a first pulling section 21, a second pulling section 22, and a third pulling section 23, arranged in sequence. The first, second, and third pulling sections 21, 22, and 23 all have different pulling directions for the yarn. The pulling direction refers to the direction in which the yarn 5 moves along each pulling section. Defining different pulling directions for each pulling section increases the complexity of the yarn pulling path, thereby achieving a certain degree of yarn tension. Furthermore, the first pulling section 21 includes multiple first pulling rollers, the second pulling section 22 includes multiple second pulling rollers, and the third pulling section 23 includes multiple third pulling rollers. The outer diameters of the first, second, and third pulling rollers are all different.

[0038] In some embodiments, see Appendix Figure 5 As shown, the winding roller assembly 4 includes a winding drive member 41, a synchronous transmission member, and a winding drum 42 mounted on the frame 1. The winding drive member 41 drives the winding drum 42 to rotate via the synchronous transmission member. The synchronous transmission member adopts a chain drive and includes a driving sprocket 431, a driven sprocket 432, and a chain 433. The driving sprocket 431 is coaxially connected to the winding drive member 41, the driven sprocket 432 is coaxially connected to the winding drum 42, and the chain 433 is arranged in a closed loop around the driving sprocket 431 and the driven sprocket 432.

[0039] It should be noted that both the pressing drive member 31 and the winding drive member 41 can be motors.

Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
