Description

Technical Field

[0001] This utility model relates to the field of high temperature and high pressure dyeing machine technology, and in particular to a high temperature and high pressure dyeing machine with an electromechanical integrated fabric lifting wheel structure. Background Technology

[0002] Existing high-temperature and high-pressure dyeing machines primarily rely on the spray pressure provided by nozzles for circulation. However, an auxiliary circulation power unit is required during the dyeing process, especially when dyeing thick or heavy fabrics. This auxiliary circulation power unit is essential. This unit is installed at the corner of the transition chamber between the main drum and the nozzle of the dyeing machine.

[0003] like Figure 1 and Figure 2 As shown, the existing high-temperature and high-pressure dyeing machine includes a main cylinder 1 and a nozzle 2. A transition device cavity 3 is installed between the main cylinder and the nozzle. A lifting wheel shaft 5 is rotatably connected inside the transition device cavity. A lifting wheel is fixedly connected to the lifting wheel shaft. A transmission wheel is set at the end of the lifting wheel shaft. The transmission wheel is driven by a three-phase asynchronous motor and a reducer 4 via belt drive. A sealing device is installed on a bearing seat on one side of the transition device cavity to seal the lifting wheel shaft and prevent dye liquor leakage during dyeing. In this high-temperature and high-pressure dyeing machine, the three-phase asynchronous motor, reducer, belt drive, lifting wheel shaft, and lifting wheel constitute an auxiliary circulation power unit. This auxiliary circulation power unit is activated when active lifting is required for dyeing heavy fabrics. When dyeing light and thin fabrics, the power source provided by the lifting wheel and the motor is manually disconnected, thus passively lifting the fabric. Its disadvantages are high energy consumption, cumbersome structure, high failure rate, cumbersome process requiring manual switching between active and passive lifting, and difficulty in achieving the process requirement of switching between active and passive lifting at any time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a high-temperature and high-pressure dyeing machine with an electromechanical integrated fabric lifting wheel structure.

[0005] The present invention adopts the following technical solution:

[0006] A high-temperature and high-pressure dyeing machine with an electromechanical integrated fabric lifting wheel structure includes a main cylinder and a nozzle. A transition device cavity is installed between the main cylinder and the nozzle. The electromechanical integrated fabric lifting wheel structure is fixedly installed in the transition device cavity. The electromechanical integrated fabric lifting wheel structure includes an inner stator of a permanent magnet motor, an outer rotor of a permanent magnet motor, and a fabric lifting wheel. The inner stator of the permanent magnet motor is fixed at both ends of the transition device cavity. The outer rotor of the permanent magnet motor is sleeved on the outer edge of the inner stator of the permanent magnet motor and driven to rotate. The fabric lifting wheel is fixedly installed on the outer edge of the outer rotor of the permanent magnet motor.

[0007] Preferably, flanges are fixedly installed at both ends of the inner stator of the permanent magnet motor, and are fixedly installed at both ends of the transition device cavity via the flanges.

[0008] Preferably, the inner stator of the permanent magnet motor includes a coil and a spindle.

[0009] Preferably, the two ends of the outer rotor of the permanent magnet motor are fixedly connected to limit bushings.

[0010] Preferably, a bearing is installed between the limiting bushing and the flange.

[0011] Preferably, the bearing is a ceramic bearing.

[0012] Preferably, limiting plates are fixedly installed on both sides of the fabric lifting wheel.

[0013] Preferably, the limiting piece is flared outward in a trumpet shape.

[0014] Preferably, the fabric lifting wheel is fitted with a rubber sleeve. The rubber sleeve on the working surface of the lifting wheel increases friction and improves efficiency during active fabric lifting. All components are made of high-temperature resistant materials, enabling the lifting wheel to withstand working environments up to 145°C.

[0015] The beneficial effects of this utility model are as follows: Based on the principle of permanent magnet motor, this utility model replaces the rotor of a conventional permanent magnet motor with an inner stator and the stator with an outer rotor. The lifting wheel is installed on the outer profile of the outer rotor, and the two ends of the inner stator spindle are fixedly installed on both sides of the transition device cavity. The lifting wheel adopts computer + PLC digital automatic control. When active assistance in lifting the cloth is required, the lifting wheel is activated; when passive lifting is required, the lifting wheel is allowed to move freely. It can switch seamlessly between active and passive assisted lifting according to the needs of the dyeing process. Furthermore, it can automatically calculate the lifting speed to match the cycle speed according to the pre-set and in-process parameters such as the specifications of the dyed fabric, the weight of the dyed fabric, the weight of the dye liquor, the nozzle pressure, and the duration of a single dyeing cycle, so that the linear speed of the lifting wheel matches the linear speed generated by the nozzle spraying the dyed fabric. This prevents the linear speed from being inconsistent with the nozzle linear speed after active lifting, thus avoiding dyeing quality defects. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0023] Example: Figures 3-5 As shown, a high-temperature and high-pressure dyeing machine with an electromechanical integrated fabric lifting wheel structure includes a main cylinder 1 and a nozzle 2. A transition device cavity 3 is installed between the main cylinder and the nozzle. The electromechanical integrated fabric lifting wheel structure is fixedly installed in the transition device cavity. The electromechanical integrated fabric lifting wheel structure includes an inner stator 10 of a permanent magnet motor, an outer rotor 9 of a permanent magnet motor, and a fabric lifting wheel 7. Flanges 6 are fixedly installed at both ends of the inner stator of the permanent magnet motor, and are fixedly installed at both ends of the transition device cavity through the flanges. The outer rotor of the permanent magnet motor is sleeved on the outer edge of the inner stator of the permanent magnet motor and driven to rotate. The fabric lifting wheel is fixedly installed on the outer side of the outer rotor of the permanent magnet motor.

[0024] The inner stator of the permanent magnet motor includes coils and a spindle. Limiting bushings 12 are fixedly connected to both ends of the outer rotor of the permanent magnet motor.

[0025] A bearing is installed between the limiting bushing and the flange. The bearing is a ceramic bearing 11. Limiting plates 8 are fixedly installed on both sides of the cloth-lifting wheel. The limiting plates are flared outward in a trumpet shape.

[0026] The fabric lifting wheel is fitted with a rubber sleeve. The rubber sleeve on the working surface of the lifting wheel increases friction and improves efficiency during active fabric lifting. All components are made of high-temperature resistant materials, enabling the lifting wheel to withstand working environments up to 145℃.

[0027] This utility model is based on the principle of permanent magnet motor. The rotor of the conventional permanent magnet motor is changed to an inner stator (i.e., coil and spindle), and the stator of the conventional permanent magnet motor is changed to an outer rotor (i.e., magnet). The cloth lifting wheel is installed on the outer contour of the outer rotor, and the two ends of the inner stator spindle are fixedly installed on both sides inside the cavity of the transition device.

[0028] The fabric lifting wheel adopts computer + PLC digital automatic control. It is activated when active fabric lifting is required and allowed to move freely when passive fabric lifting is required (at this time, the magnetic levitation effect of the permanent magnet motor can be used to make the frictional resistance of the fabric lifting wheel device infinitely close to zero). It can switch seamlessly between active and passive fabric lifting according to the needs of the dyeing process. It can also automatically calculate the fabric lifting speed to match the cycle speed according to the pre-set and real-time parameters such as the specifications of the fabric to be dyed (mainly weight / meter), the weight of the fabric to be dyed, the weight of the dye liquor, the nozzle pressure, and the duration of a single dyeing cycle. This ensures that the linear velocity of the fabric lifting wheel matches the linear velocity generated by the nozzle spraying the fabric to be dyed, preventing the inconsistency between the linear velocity and the nozzle linear velocity after active fabric lifting, which would lead to dyeing quality defects.

[0029] This utility model has a simple and compact structure, is easy and convenient to operate and use, requires no manual intervention, has low energy consumption, no noise, no leakage, reduces the failure rate, and extends the service life.

[0030] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
