Description

Technical Field

[0001] This utility model belongs to the field of spinning machine technology, specifically relating to a compensation device for a ring rail and yarn guide lifting system. Background Technology

[0002] Currently, the drafting drive system of ring spinning frames is divided into two types: mechanical drafting and fully electronic drafting. Among them, the fully electronic drafting drive system is a modification of the mechanical drafting drive system developed with the advancement of technology. The fully electronic drafting drive system can achieve more precise control of the front, middle and rear rollers in terms of transmission control. However, when configuring a ring spinning frame with a fully electronic drafting drive system, the top plane height of the short beam in the ring spinning frame will be lowered due to the need to replace the transmission gear set as required. This results in a mismatch between the original ring rail and yarn guide lifting system and the fully electronic drafting drive system. That is, a height difference inevitably occurs between the interface plane of the ring rail and yarn guide lifting system and the top plane of the short beam. Therefore, a compensation device needs to be designed to make up for this height difference so that the original ring rail and yarn guide lifting system can operate normally when the ring spinning frame is equipped with a fully electronic drafting drive system. Utility Model Content

[0003] In view of this, the present invention provides a compensation device for a steel ring plate and yarn guide plate lifting system, which aims to use the cooperation between the machine beam seat and the compensation component to achieve height compensation for the original steel ring plate and yarn guide plate lifting system, so that the fully electronic drafting transmission system can work normally.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A compensation device for a ring bar and yarn guide plate lifting system is applied in a ring spinning machine equipped with a fully electronic drafting drive system. The ring spinning machine includes a short frame beam and a frame body, with the short frame beam located on one side of the frame body. The frame body has two spinning stations, each including a yarn guide plate and a ring bar. The lifting system includes a power assembly and two sling groups corresponding to the two spinning stations. Each sling group includes two drafting slings, one end of which is connected to the yarn guide plate and the ring bar, respectively, and the other end is connected to the power assembly located inside the short frame beam. The power to the power assembly is provided by the fully electronic drafting drive system. The compensation device includes:

[0006] The machine beam support includes two, which are symmetrically arranged at the top of the short machine beam. The sum of the vertical heights of the machine beam support and the short machine beam is flush with the height of the frame body. In addition, each machine beam support is provided with a clearance hole.

[0007] The compensation components are provided in two sets, symmetrically arranged on two machine beam seats. Each set of compensation components includes an integrally formed mounting plate and a pulley seat. The mounting plate is screwed onto the machine beam seat. The pulley seat passes through the clearance hole on the machine beam seat and is located in the area between the two machine beam seats. A set of chain pulleys is rotatably arranged on the pulley seat. The set of chain pulleys cooperates with two traction belts in a sling group to change the extension direction of the traction belts.

[0008] Preferably, in the compensation assembly, the pulley seat includes a base plate, two side plates symmetrically arranged on both sides of the base plate, one of which is configured as a first side plate, the end face of the first side plate being fixedly connected to the mounting plate, and the other side plate being configured as a second side plate, the second side plate being parallel to the first side plate. In addition, a set of mounting holes are correspondingly opened on the first side plate and the second side plate, and a bridge mandrel is connected in a common set of mounting holes. An intermediate bushing is fitted in the middle of the bridge mandrel, and end bushings are fitted at both ends of the bridge mandrel. A rolling bearing is provided between each end bushing and the intermediate bushing, and the chain pulley is fitted on the outer circumference of each rolling bearing.

[0009] Preferably, in the compensation assembly, a threaded hole is provided on the second side plate, and a limiting bolt is fitted in the threaded hole. The limiting bolt passes through the threaded hole and extends into the mounting hole, and abuts against the outer circumferential wall of the bridge mandrel.

[0010] Preferably, in the compensation assembly, the thickness of the first side plate is greater than the thickness of the second side plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] In general, the compensation device for the ring rail and yarn guide plate lifting system provided by this utility model compensates for the height difference between the top surface of the short beam and the spinning station of the spinning machine by using the machine beam seat, and changes the extension direction of the traction belt in the lifting system by using the chain pulley in the compensation component, so that one end of the traction belt is connected to the power component of the lifting system, and the other end is connected to the spinning station in a horizontal form, preventing interference between the traction belt and the spinning station, and ensuring the normal operation of the all-electronic drafting transmission system.

[0013] In addition, threaded holes are provided on the second side plate of the compensation component, and the limit bolts are used to fix the bridge mandrel in the mounting hole to prevent the bridge mandrel from rotating or moving axially. On this basis, the thickness of the first side plate is greater than the thickness of the second side plate, so that after the chain pulley and the traction belt are engaged, interference between the traction belt and the machine beam seat is prevented.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] 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, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] In this technical solution, such as Figure 1-2As shown, a compensation device for a ring bar and guide plate lifting system is applied in a ring spinning machine equipped with a fully electronic drafting transmission system. The ring spinning machine includes a short frame beam 1 and a frame body 2, with the short frame beam 1 located on one side of the frame body 2. The frame body 2 has two spinning stations, and each spinning station includes a guide plate 7 and a ring bar 8. In addition, the lifting system includes a power assembly 5 and two sling groups 6 corresponding to the two spinning stations, and each sling group 6 includes two drafting slings 601. One end of the two drafting slings 601 is connected to the guide plate 7 and the ring bar 8 respectively, and the other end is connected to the power assembly 5 located inside the short frame beam 1. The power of the power assembly 5 is provided by the fully electronic drafting transmission system.

[0022] For ease of understanding, it should be noted in this application that: the lifting system is an essential transmission system in the core process of spinning and winding yarn using the guide plate 7 and the ring rail 8 in existing ring spinning machines. Therefore, it is equipped in conventional ring spinning machines. In addition to the power unit 5 and the lifting belt group 6, the lifting system also includes a steering wheel 10 that is installed on the spinning station. The lifting belt 601 is connected to the guide plate 7 and the ring rail 8 after being turned by the steering wheel 10, and realizes the lifting and reciprocating motion of the guide plate 7 and the ring rail 8 under the power provided by the power unit 5.

[0023] Since the core of this application is to solve the problem that the height of the short beam 1 in a spinning frame equipped with a fully electronic drafting drive system is not compatible with the lifting system configured in the original spinning station, this application only provides a rough description of the structure and function of the lifting system and the fully electronic drafting drive system. These are not the core innovations of this application. Furthermore, since both the lifting system and the fully electronic drafting drive system are existing technologies, those skilled in the art can learn about their specific structure and operation through existing patent documents and other channels.

[0024] In the compensation device provided in this application, such as Figure 1-4 As shown, the compensation device includes: a beam support 3 and a compensation assembly 4, wherein:

[0025] The machine beam base 3 includes two, which are symmetrically arranged at the top of the short machine beam 1. The sum of the vertical heights of the machine beam base 3 and the short machine beam 1 is flush with the height of the frame body 2. In addition, each machine beam base 3 is provided with a clearance hole 301.

[0026] The compensation components 4 are provided in two sets, symmetrically arranged on the two machine beam supports 3, wherein, for example... Figure 2-3As shown, each compensation component 4 includes an integrally formed mounting plate 401 and a pulley seat 402. The mounting plate 401 is screwed onto the machine beam seat 3. The pulley seat 402 passes through the clearance hole 301 on the machine beam seat 3 and is located in the area between the two machine beam seats 3. A set of chain pulleys 9 are rotatably mounted on the pulley seat 402. The set of chain pulleys 9 cooperates with two traction belts 601 in a sling group 6 to change the extension direction of the traction belts 601.

[0027] Specifically, such as Figure 3-4 As shown, in the compensation assembly 4, the pulley seat 402 includes a base plate 403. Two side plates are symmetrically arranged on both sides of the base plate 403. One of the side plates is configured as a first side plate 404, and the end face of the first side plate 404 is fixedly connected to the mounting plate 401. The other side plate is configured as a second side plate 405, and the second side plate 405 is parallel to the first side plate 404. In addition, a set of mounting holes 406 are correspondingly opened on the first side plate 404 and the second side plate 405. A bridge mandrel 407 is connected in the set of mounting holes 406. An intermediate bushing 408 is sleeved in the middle of the bridge mandrel 407. End bushings 409 are sleeved at both ends of the bridge mandrel 407. A rolling bearing 410 is provided between each end bushing 409 and the intermediate bushing 408. A chain pulley 9 is sleeved on the outer circumference of each rolling bearing 410.

[0028] Based on the above embodiments, the intermediate bushing 408 separates the two rolling bearings 410, preventing the two chain pulleys 9 from interfering with each other after the rolling bearings 410 are engaged with the chain pulleys 9.

[0029] like Figure 4 As shown, in the compensation component 4, a threaded hole 411 is provided on the second side plate 405, and a limiting bolt 412 is fitted in the threaded hole 411. The limiting bolt 412 passes through the threaded hole 411 and extends into the mounting hole 406, and abuts against the outer circumferential wall of the bridge mandrel 407.

[0030] Based on the above embodiments, the limiting bolt 412 and the threaded hole 411 are used to fix the bridge mandrel 407 in the mounting hole 406, preventing the bridge mandrel 407 from rotating or moving axially, thereby improving the stability of the chain pulley 9.

[0031] In addition, in the compensation component 4, the thickness of the first side plate 404 is greater than the thickness of the second side plate 405. This arrangement prevents the chain pulley 9 from interfering with the traction belt 601 after they are engaged with each other.

[0032] Specifically, this utility model provides a compensation device for a ring rail and yarn guide lifting system. It uses the machine beam base 3 to compensate for the insufficient height of the short machine beam 1, and a compensation component 4 is set on the machine beam base 3 corresponding to the lifting belt 601 of the lifting system. By using the cooperation between the chain pulley 9 in the compensation component 4 and the lifting belt 601, the horizontal height of the part of the lifting belt 601 that enters the spinning station is raised, so that it cooperates with the steering wheel 10 in the spinning station and enters the spinning station in a more horizontal form. This prevents the lifting belt 601 from interfering with other components in the spinning station and the machine frame body 2 during operation. Since the power of the power component 5 is provided by the fully electronic drafting transmission system, the compensation device also ensures the normal operation of the fully electronic drafting transmission system.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
