Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to a motor for a false twister. Background Technology

[0002] A false twister is a key piece of equipment in the textile industry used to false twist yarns. Its main function is to simulate twist to give the yarn a certain degree of twisting during the weaving process, thereby improving the elasticity and hand feel of the fabric.

[0003] Existing false twister motors mostly adopt traditional motor structures, which have the following technical problems:

[0004] First, traditional belt conveyors and external motors have complex structures, many parts, and cumbersome assembly processes. Changing the Z-twist and S-twist requires changing the position of the drive shaft, resulting in low production efficiency and high costs. Moreover, maintenance requires professional technicians, and replacing parts is difficult, which increases the cost of use.

[0005] Secondly, traditional false twist motors typically employ a structure where the rotor and shaft are separate. While this design meets functional requirements to some extent, it has some shortcomings in practical applications. For example, the connection between the rotor and shaft may introduce additional friction and clearance, reducing mechanical transmission efficiency and increasing energy loss. At the same time, structural complexity may also lead to increased manufacturing costs and maintenance difficulties. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a motor for a false twister. The motor for a false twister of this invention has a simple structure, is easy to maintain, and has high mechanical transmission efficiency.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a motor for a false twister, comprising a drive shaft, a stator, a stator housing, and a mounting base. The drive shaft is correspondingly disposed to the stator and has a gap therebetween. The stator is fixedly connected to the inner sidewall of the stator housing. The stator housing is detachably connected to the mounting base. The drive shaft passes through the interior of the mounting base and is rotatably connected to the mounting base. The drive shaft includes an integrally formed false twist shaft and a rotor. Gears and bearings are sleeved on the false twist shaft, and the rotor is located inside the stator.

[0008] Preferably, the stator includes a stator core, stator windings, and a terminal block. The bottom of the stator housing is provided with a fixing groove and a base. The terminal block is disposed in the fixing groove, and the base is used to fix the terminal block. The terminal block includes a top interface and a side interface.

[0009] Preferably, the mounting base has two driven shafts rotatably connected to the drive shaft, each driven shaft is fitted with a gear and a bearing, and the three gears mesh with a gear belt for synchronous transmission.

[0010] Preferably, the driving shaft and the two driven shafts are arranged in an equilateral triangle on the mounting base.

[0011] Preferably, the mounting base has a retaining ring at one end near the stator housing, the retaining ring being integrally formed with the mounting base, and the retaining ring being engaged with the inner side of the top of the stator housing.

[0012] Preferably, the outer circumferential array of the retaining ring is provided with a plurality of fixing blocks, and an annular groove is formed between the fixing blocks and the retaining ring, the annular groove being used to fix the top of the stator shell.

[0013] Preferably, the top of the drive shaft and the driven shaft are provided with threaded holes.

[0014] Preferably, the outer sidewall of the bearing is provided with an oiling hole.

[0015] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0016] The motor for the false twister provided by this utility model directly drives the drive shaft, eliminating the need for physical movement or replacement of the drive shaft position in traditional false twisters to change the twist direction. Since the drive shaft position is fixed, there is no need to change its location; the twist direction can be switched simply by changing the drive shaft's rotation. The drive shaft and driven shaft are arranged parallel to each other and synchronously driven by gears and belts, allowing all shafts to rotate together in the same or opposite directions. Because the friction disc, false twist shaft, and drive shaft structure do not require disassembly, only motor reversal control is needed, eliminating the need to change shaft positions. This reduces deviations caused by human disassembly, assembly errors, or shaft movement, thereby improving stability and reliability. This process eliminates mechanical disassembly and assembly operations, shaft adjustments, and component replacements, reducing labor and downtime. Furthermore, the quick twist direction switching equipment has a shorter conversion time, increasing production flexibility and capacity.

[0017] The false twister motor provided by this utility model features a design with a gap between the drive shaft and the stator. The stator housing is detachably connected to the mounting base, and the drive shaft passes through and rotatably connects to the mounting base. Furthermore, the drive shaft includes an integrally formed false twist shaft and rotor, with gears and bearings fitted onto the false twist shaft. This design reduces the number of parts, simplifies the assembly process, improves production efficiency, and lowers costs. Moreover, the motor's design makes assembly easier, eliminating the need for complex disassembly during maintenance, thus reducing maintenance costs and improving the maintainability of the equipment.

[0018] The false twister motor provided by this utility model eliminates the loosening or misalignment problems that may occur when the false twist shaft and rotor are connected separately in traditional motors by integral molding of the false twist shaft and rotor. This improves the stability and reliability of the motor and reduces energy loss.

[0019] The false twister motor provided by this utility model is connected to the mounting base by a retaining ring and a fixing block, which enhances the connection between the stator housing and the mounting base, ensures the safety of the motor during operation, and reduces failures caused by loose connections.

[0024] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Example 1

[0026] like Figure 1-3 As shown, this utility model provides a motor for a false twister, including a drive shaft 1, a stator 2, a stator housing 3, and a mounting base 4. The drive shaft 1 is correspondingly arranged with the stator 2 and has a gap. The stator 2 is fixedly connected to the inner side wall of the stator housing 3. The stator housing 3 is detachably connected to the mounting base 4. The drive shaft 1 passes through the interior of the mounting base 4 and is rotatably connected to the mounting base 4.

[0027] The drive shaft 1 includes an integrally formed false twist shaft 101 and a rotor 102. The false twist shaft 101 is fitted with a gear 103 and a bearing 104. The false twist shaft 101 is used to cooperate with the friction disc to achieve false twist deformation of the yarn. The rotor 102 is located inside the stator 2.

[0028] This invention utilizes a motor to achieve false twisting of the yarn through electromagnetic induction. When the motor is energized, the stator 2 generates a rotating magnetic field under the influence of the current, driving the rotor 102 located inside the stator to rotate. The rotor 102 is coaxially and integrally connected to the false twist shaft 101. During rotation, the false twist shaft 101 drives the gear 103 and bearing 104 mounted on it to rotate together. Several friction discs are mounted on the false twist shaft 101, which contact the yarn and cause false twisting deformation through friction. This structure simplifies the transmission system of traditional motors and improves working efficiency. By directly driving the drive shaft 1, it eliminates the need for transmission components that require physical movement or replacement of the drive shaft position in traditional false twisters to change the twist direction. Since the position of the drive shaft 1 is fixed, there is no need to change the shaft position; the twist direction can be switched by changing the direction of the drive shaft 1. The drive shaft 1 and the driven shaft 5 are arranged parallel to each other, and the gear 103 enables synchronous transmission of the three shafts, allowing all shafts to rotate together in the same or opposite directions. The change in twist direction is essentially a change in rotation direction. After the motor reverses, the rotation direction of the drive shaft 1 and all friction disc assemblies reverses, thereby changing the false twist direction. Since the friction discs, false twist shaft 101, and rotor 102 do not need to be disassembled, only the motor needs to be reversed. There is no need to change the shaft position, reducing deviations caused by human disassembly, assembly errors, or shaft movement, thus improving stability and reliability. This process eliminates mechanical disassembly and assembly operations, shaft adjustments, and parts replacement, reducing labor and downtime. Moreover, the quick twist direction switching equipment has a short conversion time, increasing production flexibility and capacity.

[0029] The false twist shaft 101 and the rotor 102 are connected as a single unit, which eliminates the loosening or misalignment problems that may be caused by the separate connection of the rotor and shaft in traditional motors. This improves the stability and reliability of the motor, while reducing additional connecting parts and space requirements, thus improving the space utilization of the motor and facilitating the miniaturization and weight reduction of the equipment.

[0030] Furthermore, in another embodiment, the stator 2 includes a stator core 201, a stator winding 202, and a terminal block 203. The stator housing 3 has a fixing groove and a base 301 at its bottom. The terminal block 203 is disposed in the fixing groove, and the base 301 is used to fix the terminal block 203. The terminal block 203 includes a top interface 2031 and a side interface 2032. The top interface 2031 is used to connect to an external power supply line, and the side interface 2032 is used to connect to internal winding leads. This optimizes the heat dissipation performance of the motor, ensures that the motor can maintain a stable working state even when running under high load, and extends the service life of the motor.

[0031] Furthermore, in another embodiment, two driven shafts 5 parallel to the drive shaft 1 are rotatably connected within the mounting base 4. Each driven shaft 5 is fitted with a gear 103 and a bearing 104. The three gears 103 mesh synchronously via a toothed belt. This synchronous transmission ensures that the three false-twist shafts can operate simultaneously, resulting in efficient and stable power transmission, reduced energy loss, and improved overall motor efficiency.

[0032] Furthermore, in another embodiment, the driving shaft 1 and the two driven shafts 5 are arranged in an equilateral triangle on the mounting base 4, so that the friction disc is subjected to uniform force and the yarn false twist stability is higher.

[0033] Furthermore, in another embodiment, the mounting base 4 is provided with a retaining ring 401 at one end near the stator housing 3. The retaining ring 401 is integrally formed with the mounting base 4 and is engaged with the inner side of the top of the stator housing 3, making assembly easier and eliminating the need for a complicated disassembly process during maintenance, thereby reducing maintenance costs and improving the maintainability of the equipment.

[0034] Furthermore, in another embodiment, the outer circumferential array of the retaining ring 401 is provided with a plurality of fixing blocks 402, and an annular groove is formed between the fixing blocks 402 and the retaining ring 401. The annular groove is used to fix the top end of the stator housing 3. The fixing blocks 402 and 401 cooperate to form an annular groove, which further enhances the connection between the stator housing and the mounting base, ensures the safety of the motor during operation, and reduces failures caused by loose connections.

[0035] Furthermore, in another embodiment, the top of the drive shaft 1 and the driven shaft 5 are provided with threaded holes for use with other structures.

[0036] Furthermore, in another embodiment, the outer sidewall of the bearing 104 is provided with an oiling hole 105. The oiling hole 105 facilitates bearing lubrication, reduces friction, lowers wear, ensures smooth motor operation, and extends the service life of the equipment.

[0037] Working principle: When the motor is powered on, the stator winding 202 in the stator 2 generates a rotating magnetic field under the action of the current. This rotating magnetic field drives the rotor 102 located inside the stator 2 to rotate. The rotor 102 is coaxially and integrally connected with the false twist shaft 101. Therefore, the rotation of the rotor directly drives the rotation of the false twist shaft 101. The false twist shaft 101 is equipped with a gear 103 and a bearing 104, and cooperates with multiple friction discs. During the rotation, the friction discs contact the yarn, and the yarn undergoes false twist deformation through friction. This simplifies the transmission system of the traditional motor and improves the working efficiency.
