AI Technical Summary
In existing spinning machinery, the rotation speed of the rollers is uneven and unstable, causing the speed at which the yarn wraps around the spindle in the middle area of the rollers to lag behind that at both ends, thus reducing production efficiency.
An auxiliary drive assembly works in conjunction with the drive assembly to drive the front and rear groups of the roller assembly to rotate simultaneously. A large driving force is achieved through the gearbox and drive components to ensure that the rotation speed of the middle area is consistent with that of the end. A protective box and heat dissipation mesh are used to protect the gearbox.
This achieved uniformity and stability of the roller device's rotation speed, improved the consistency of yarn winding speed on the spindle, and increased production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, and in particular to a drafting roller system for spinning machinery. Background Technology
[0002] The spinning machine includes a back roller, a middle roller, and a front roller connected to a support frame. The yarn is processed (from coarse to fine) through the cooperation of the back roller group, the middle roller group, and the front roller group. Subsequently, several yarns output from the front roller group are wound onto corresponding spindles. The front roller group includes a left front roller and a right front roller rotatably connected to the support frame, and each front roller is relatively long (refer to the existing patent: A spinning machine, publication number "CN 211645484U", publication date: 2020.10.09). During operation, each front roller is equipped with a rotating device at both ends to drive its rotation (the principle of the rotating device driving the front roller to rotate is referenced in the existing patent: A Simple Roller Drive Assembly, Publication No.: CN 116446081A, Publication Date: 2023.07.18). During operation, the two rotating devices drive the two ends of the roller to drive the overall rotation of the roller. However, due to the long length of the roller, the driving force gradually weakens along the length of the roller. Therefore, the rotation speed in the middle area of the roller lags behind the rotation speed at both ends, resulting in uneven and unstable overall rotation speed of the roller. Consequently, the speed at which the yarn in the middle area of the roller winds around the spindle lags behind the speed at which the yarn winds around the spindle at both ends, reducing production efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a drafting roller system for spinning machinery, which solves the problem that the overall rotation speed of the existing rollers is uneven and unstable, causing the consistency of yarn winding around the spindle in the middle area of the roller to lag behind that of the yarn winding spindles at both ends, thus reducing production efficiency.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a drafting roller system for spinning machinery, including a roller assembly and drive components disposed at both ends of the roller assembly for rotating the rollers in the roller assembly. The roller assembly includes a front group and a rear group arranged sequentially along the length direction. The drive components are disposed at the far ends of the front group and the rear group, and an auxiliary drive component is connected between the near ends of the front group and the rear group. The auxiliary drive component cooperates with the drive components disposed on the front group and the rear group to drive the rollers in the front group and the rear group to rotate simultaneously.
[0005] Furthermore, the auxiliary drive assembly includes a gearbox connecting the front group and the rear group to adjacent ends, and a drive component that drives the gearbox to operate.
[0006] Furthermore, the auxiliary drive assembly also includes a protective housing for protecting the gearbox, with the gearbox disposed inside the protective housing.
[0007] Furthermore, the protective box is equipped with a heat dissipation mesh.
[0008] Furthermore, the length of the front group is similar to the length of the rear group.
[0009] Furthermore, the length of the front group is greater than the length of the rear group, or the length of the rear group is greater than the length of the front group.
[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a drafting roller system for spinning machinery, including a roller assembly and drive components disposed at both ends of the roller assembly for driving the roller assembly to rotate. The roller assembly includes a front group and a rear group arranged sequentially along its length. The drive components are disposed at the far ends of the front group and the rear group, and auxiliary drive components are connected to the near ends of the front group and the rear group. The auxiliary drive components cooperate with the drive components disposed on the front group and the rear group to drive the rollers in the front group and the rear group to rotate simultaneously. The driving force provided by the auxiliary drive components in cooperation with the drive components is relatively large. Although this large driving force gradually weakens along the length of the front or rear group, it can still ensure that the rotation speed of the middle area of the front or rear group is the same as the rotation speed of the end, thus ensuring the uniformity and stability of the overall rotation speed. This ensures that each yarn conveyed by this roller device winds onto the spindle at a consistent speed, improving yarn production efficiency. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0015] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0016] Example 1 refer to Figure 1 , Figure 2 and Figure 3For example, a drafting roller system for a spinning machine includes a roller assembly 1 and drive assemblies 2 disposed at both ends of the roller assembly 1 for rotating the roller assembly 1. The drive assemblies 2 can be electronic drafting drive assemblies or mechanical drafting drive assemblies. The roller assembly 1 includes a front group 11 and a rear group 12 arranged sequentially along its length. In this example, the length of the front group 11 and the rear group 12 are the same. Both the front group 11 and the rear group 12 include a rear roller 111, a middle roller 112, and a front roller 113. Drive assemblies 2 are disposed at the far ends of the front group 11 and the rear group 12, and auxiliary drive assemblies 3 are connected to the near ends of the front group 11 and the rear group 12. The auxiliary drive assemblies 3 cooperate with the drive assemblies 2 disposed on the front group 11 and the rear group 12 to drive the rollers in the front group 11 and the rear group 12 to rotate simultaneously. The auxiliary drive assembly 3 is located in the middle of the roller assembly 1. The auxiliary drive assembly includes a gearbox that connects the front and rear groups to the near ends and a drive component that drives the gearbox (the gearbox and drive component are not shown in the figure).
[0017] refer to Figure 1 , Figure 2 and Figure 3 During operation, the drive assembly 2, which drives the front group 11 and the rear group 12 to rotate respectively, and the auxiliary drive assembly 3, which drives the front group 11 and the rear group 12 to rotate simultaneously, are first adjusted to make the drive speeds of the drive assembly 2 and the auxiliary drive assembly 3 the same. Then, through the cooperation of the drive assembly 2 and the auxiliary drive assembly 3, the rollers in the corresponding front group 11 and the rear group 12 are driven to rotate simultaneously. The drive force provided by the auxiliary drive assembly 3 in cooperation with the drive assembly 2 is relatively large. Although this relatively large drive force gradually weakens along the length of the front group 11 or the rear group 12, it can still ensure that the rotation speed of the middle area of the front group 11 or the rear group 12 is the same as the rotation speed of the end, which can ensure the uniformity and stability of the overall rotation speed. This ensures that the speed at which each yarn conveyed by this roller device winds onto the spindle is consistent, thereby improving yarn production efficiency.
[0018] refer to Figure 1 and Figure 4 The auxiliary drive assembly 3 also includes a protective housing 4 that protects the gearbox, with the gearbox housed inside the protective housing 4. The drive motor is also installed inside the protective housing 4; the protective housing 4 protects the gearbox and prevents cotton lint from falling from the yarn from accumulating on the gearbox; by integrating the two gearboxes into the same protective housing 4, the structure is compact and the occupied area is reduced.
[0019] refer to Figure 1 and Figure 4 After prolonged operation, the gearbox is prone to generating heat. The protective box 4 is equipped with a heat dissipation mesh 6, which can dissipate and cool the generated heat, preventing the temperature inside the protective box 4 from becoming too high and affecting the normal operation of the gearbox.
[0020] Example 2 This embodiment has a basically the same structure as Embodiment 1, except that: refer to Figure 5 The length of the front group 11 is greater than the length of the rear group 12, or the length of the rear group 12 is greater than the length of the front group 11. In this example, the length of the front group 11 is greater than the length of the rear group 12. The auxiliary drive component 3 is located in the middle of the roller assembly 1, slightly to the right. The length of the front group 11 can be selected based on the condition that the cooperation between the drive component 2 and the auxiliary drive component 3 can ensure the uniform and stable rotation of the front group as a whole. The length of the rear group 12 is shorter, and the drive component 2 and the auxiliary drive component 3 are sufficient to ensure the uniformity and stability of the rotation of the rear group 12 as a whole.
[0021] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
