Description

Technical Field

[0001] This utility model relates to the field of texturing machine control technology, and in particular to a dual-switch TMT texturing machine with power failure restart function. Background Technology

[0002] TMT texturing machines are used in the textile and chemical fiber processing industry.

[0003] Existing TMT texturing machines employ an automatic temperature control device for the electrical control cabinet, as disclosed in announcement number CN222801056U. This device controls the internal temperature of the control cabinet based on temperature changes, ensuring a stable temperature that does not rise with the external temperature. This reduces inverter tripping accidents in the control cabinet, thereby minimizing machine downtime. However, TMT texturing machines consistently suffer from frequent tripping due to overheating or malfunction of the power switches on the PSA and PSB circuits. Existing TMT texturing machines, like this one, often use a single-wire circuit structure. When this circuit short-circuits, the circuit is immediately broken, cutting off the power and causing the machine to stop immediately. Immediate repair is necessary to minimize the impact on textile and chemical fiber processing, but this requires significant time and manpower and necessitates prolonged restarts, severely delaying processing. This has a substantial negative impact on performance indicators, production costs, and employee workload. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the efficiency of the existing TMT texturing machine is easily affected by power outages due to short circuits, and to propose a dual-switch TMT texturing machine with a power failure restart function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-switch TMT texturing machine with power failure and restart function includes a chassis with a built-in main power supply. The chassis has a first path and a second path that are symmetrically connected to the main power supply. The chassis also has a fuse switch for controlling the on / off state of the first path and the second path.

[0007] Preferably, the first path includes a first live wire and a first neutral wire, and the first live wire is provided with a first upper conductive terminal and a first lower conductive terminal; the second path includes a second live wire and a second neutral wire, and the second live wire is provided with a second upper conductive terminal and a second lower conductive terminal.

[0008] Preferably, the fuse switch includes a lower bracket and an upper bracket fixedly mounted inside a chassis. A thermal sensor fixedly mounted on the lower bracket and fixedly connected to a first lower conductive terminal is also fixedly mounted on the lower bracket. A thermal actuator fixedly connected to the thermal sensor is also fixedly mounted on the lower bracket. A lifting rack fixedly connected to the output end of the thermal actuator is slidably mounted inside the chassis. A transmission shaft is rotatably mounted on the upper bracket. A driven gear meshing with the lifting rack is keyed to the transmission shaft. A deflection lever is fixedly mounted on the transmission shaft. A movable slider movably pulled by the deflection lever is slidably mounted on the upper bracket. Conductive blocks corresponding to the first upper conductive terminal, the first lower conductive terminal, the second upper conductive terminal, and the second lower conductive terminal are fixedly connected to both ends of the movable slider.

[0009] Preferably, the upper bracket is located between the first live wire and the second live wire, and the movable slider is located between the first upper conductive end, the first lower conductive end and the second upper conductive end, the second lower conductive end.

[0010] Preferably, the thermal sensor is electrically connected to the thermal driver.

[0011] Preferably, a traction hole is provided at the free end of the deflection lever, and a traction bolt that is slidably fitted into the traction hole is integrally connected to the movable slider.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model sets up a first path and a second path that are electrically connected to the main power supply inside the chassis, and designs the first live wire and the second live wire in the first path and the second path to disconnect the circuit respectively, so that the first path is used to power the chassis under normal conditions. At the same time, a thermal sensor is set up to monitor the first path for short circuit and temperature monitoring, so as to monitor and judge whether the first path is operating normally.

[0014] 2. This utility model provides a fuse switch located between the first and second live wires inside the chassis. A thermal actuator electrically connected to a thermal sensor is included, so that when a short circuit occurs in the first path, the abnormal high temperature information is received, which drives the lifting rack to move vertically up and down, thereby driving the transmission shaft to rotate, which in turn drives the moving slider and conductive block to move linearly, cutting off the first path and connecting the second path at the same time, providing a safe power supply for the chassis that can be restarted instantly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5A dual-switch TMT texturing machine with power failure and restart function includes a chassis 1 with a built-in main power supply 2. The input and output voltage of the main power supply 2 is 220V. The chassis 1 is symmetrically equipped with a first path 3 and a second path 4 that are electrically connected to the main power supply 2. The ends of the first path 3 and the second path 4 away from the main power supply 2 are connected to the relevant equipment of the TMT texturing machine. By setting a transformer between the first path 3 and the second path 4 of the main power supply 2, the normal voltage of the first path 3 is 26.5V and the normal voltage of the second path 4 is 26V. It should be noted that the higher voltage is given priority, so the power switch current of the first path 3 is set to be large and starts running first. The added second path 4 is in standby mode. When the main power supply 2 trips and the voltage is zero, the circuit of the added second path 4 switch is immediately switched to start the switching power supply. The chassis 1 will not trip due to the failure of the main power supply 2 switch. The first path 3 includes a first live wire and a first neutral wire, and the first live wire is provided with a first upper conductive terminal 31 and a first lower conductive terminal 32. The second path 4 includes a second live wire and a second neutral wire, and the second live wire is provided with a second upper conductive terminal 41 and a second lower conductive terminal 42. A conductive block 510 is provided between the first upper conductive terminal 31 and the first lower conductive terminal 32, and between the second upper conductive terminal 41 and the second lower conductive terminal 42. Under normal operating conditions, the chassis 1 is powered through the first path 3. At this time, the conductive block 510 in the first path 3 contacts the first upper conductive terminal 31 and the first lower conductive terminal 32 to conduct electricity.

[0023] The chassis 1 is also equipped with a fuse switch 5 for controlling the connection and disconnection of the first path 3 and the second path 4, as detailed in the instruction manual. Figure 3 -Appendix Figure 5When the first passage 3 inside the chassis 1 is broken, the thermal sensor 53 immediately senses the abnormal temperature of the first lower conductive terminal 32 in the first live wire, and causes the thermal driver 54 to start running through signal transmission. A PLC control center can be set between the thermal sensor 53 and the thermal driver 54 to realize the transmission and processing of electrical signals, so that the thermal driver 54 can perform real-time opening and closing control according to the thermal sensor 53. The fuse switch 5 includes a lower bracket 51 and an upper bracket 52 fixedly mounted inside the housing 1. A thermal sensor 53 fixedly mounted on the lower bracket 51 and fixedly connected to the first lower conductive terminal 32, and a thermal actuator 54 fixedly mounted on the lower bracket 51 and fixedly connected to the thermal sensor 53, are slidably mounted inside the housing 1 and fixedly connected to the output end of the thermal actuator 54. A transmission shaft 56 is rotatably mounted on the upper bracket 52. A driven gear 57 that meshes with the lifting rack 55 is keyed to the transmission shaft 56, and a deflection lever 58 is fixedly mounted on the transmission shaft 56. A movable slider 59 that is movably pulled by the deflection lever 58 is slidably mounted on the upper bracket 52. Conductive blocks 510 corresponding to the first upper conductive terminal 31, the first lower conductive terminal 32, the second upper conductive terminal 41, and the second lower conductive terminal 42 are fixedly connected to both ends of the movable slider 59. When the movable slider 59 is in position... When the upper bracket 52 is in the middle position, both the first passage 3 and the second passage 4 are in an open circuit state. When the chassis 1 is in normal operation, a conductive block 510 on the left end of the movable slider 59 contacts the first upper conductive end 31 and the first lower conductive end 32, so that the first passage 3 is energized. At this time, the temperature of the first lower conductive end 32 is 98-109℃. When a short circuit occurs in the first passage 3, the temperature of the first lower conductive end 32 rises to 165-182℃ within 0.85-1.03s. The thermal sensor 53 immediately senses the abnormal temperature value and drives the thermal actuator 54 to start running. The movable slider 59 drives the conductive block 510 to disengage from the first upper conductive end 31 and the first lower conductive end 32. At the same time, another conductive block 510 and the second upper conductive end 41 and the second lower conductive end 42 come into contact, thus realizing the disconnection of the first passage 3 and the opening of the second passage 4.

[0024] The upper bracket 52 is located between the first live wire and the second live wire, and the movable slider 59 is located between the first upper conductive end 31, the first lower conductive end 32 and the second upper conductive end 41, the second lower conductive end 42. By moving the two conductive blocks 510 between the first live wire and the second live wire, the on / off control of the first live wire and the second live wire can be achieved.

[0025] The thermal sensor 53 is electrically connected to the thermal driver 54. By setting up a PLC control center between the thermal sensor 53 and the thermal driver 54, it is possible to realize real-time processing of electrical signal information.

[0026] A traction hole is provided at the free end of the deflection lever 58, and a traction bolt is integrally connected to the movable slider 59 and slidably fitted into the traction hole. The deflection lever 58 enables bidirectional driving of the movable slider 59, allowing the two conductive blocks 510 to be adjusted in position according to the opening and closing requirements of the first passage 3 and the second passage 4.

[0027] This measure helps reduce machine downtime, increase output, improve the rate of high-quality products, reduce waste yarn rate, reduce the labor intensity of employees, maintain stable production, and increase economic benefits.

[0028] It should be noted that the specific models and specifications of the chassis 1, main power supply 2, thermal sensor 53 and thermal driver 54 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] The chassis 1 is powered by the main power supply 2 through the first channel 3. The thermal sensor 53 monitors the temperature of the first live wire in the first channel 3. During this process, the moving slider 59 tends to move closer to the left side of the first live wire, that is, the conductive block 510 on the left end of the moving slider 59 abuts against the first upper conductive end 31 and the first lower conductive end 32.

[0031] When a short circuit occurs in the first circuit 3, the temperature rises sharply. After the thermal sensor 53 detects the high temperature, it transmits information to activate the thermal actuator 54. The thermal actuator 54 drives the lifting rack 55 to move upward, which drives the transmission shaft 56 to rotate through the driven gear 57. The transmission shaft 56 drives the deflection lever 58 to deflect. The deflection lever 58 drives the moving slider 59 to move closer to the right side of the second fire wire through the traction hole and traction bolt. At the same time, one conductive block 510 on the left end of the moving slider 59 disengages from the first upper conductive end 31 and the first lower conductive end 32, while another conductive block 510 on the right end of the moving slider 59 abuts against the second upper conductive end 41 and the second lower conductive end 42, thereby providing subsequent power to the main power supply 2.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
