Description

Technical Field

[0001] This utility model relates to the field of textile machinery, specifically a PLC controller for textile machinery. Background Technology

[0002] Originally, textiles referred to the general concepts of spinning and weaving. However, with the continuous development and improvement of textile knowledge and disciplines, especially with the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, textiles today are no longer limited to traditional hand spinning and weaving. They also include nonwoven fabric technology, modern three-dimensional weaving technology, and modern electrostatic nanofiber web forming technology, used for clothing, industrial, and decorative textiles. Therefore, modern textiles refer to a multi-scale structural processing technology for fibers or fiber assemblies. Modern textile machines, equipped with PLC controllers, improve the efficiency and stability of automated control.

[0003] The existing devices have the following shortcomings when in use: the PLC controller for textile machines has poor heat dissipation after long-term operation, resulting in excessive internal temperature, which affects the normal operation and service life of the PLC controller. When disassembling and assembling the PLC controller, tools are required to pry open the outer shell and various component boards, which is inconvenient and can easily damage the outer shell and various component boards. Utility Model Content

[0004] The purpose of this invention is to provide a PLC controller for textile machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PLC controller for textile machines, comprising a PLC controller housing, a housing cover, a power board, a heat sink, a ventilation duct, and a control interface board. The power board and control interface board are installed in the PLC controller housing from bottom to top. A housing cover is installed on the top of the PLC controller housing, and an installation window is provided on the housing cover. A heat sink is installed in the installation window via screws. A fan is installed in the heat sink, and a filter is installed at the air inlet of the heat sink. A ventilation duct is installed in the housing cover, with one end of the ventilation duct connected to the installation window. A ventilation channel is provided in the inner wall of the PLC controller housing, and the other end of the ventilation duct is inserted into the ventilation channel. An air outlet is provided on the inner wall of the PLC controller housing, connected to the ventilation channel. An air outlet is provided on the PLC controller housing.

[0006] By adopting the above technical solution, the cover is installed on the PLC controller housing, and one end of the ventilation pipe on the cover is inserted into the ventilation channel opened in the inner wall of the PLC controller housing. The heat sink is installed in the installation window by screws. The fan inside the heat sink is driven by an external power supply, generating airflow. The rotation of the fan drives the air to enter from the air inlet of the heat sink. After passing through the filter screen, dust and impurities are removed, ensuring that the air entering the PLC controller is clean. The filtered air enters the ventilation channel through the ventilation pipe, and then blows through the air outlet to each layer of component boards inside the PLC controller, such as the power board and control interface board. This allows the air to circulate between each layer of component boards, effectively carrying away the heat generated by these components. Finally, the hot air is discharged from the PLC controller housing through the air outlet, forming a complete heat dissipation cycle. This prevents the PLC controller from overheating, which could lead to equipment failure or performance degradation, and improves the heat dissipation efficiency and effectiveness of the PLC controller.

[0007] Preferably, the power board and the control interface board are provided with mounting slots, a spring column is installed in the mounting slot, a fixing rod is installed at one end of the spring column, a fixing slot is provided on the outer wall of the PLC controller housing, the fixing rod is slidably connected to the fixing slot, and a semi-circular silicone cover is installed on the PLC controller housing outside the fixing slot.

[0008] Using the above technical solution, when it is necessary to fix the power board and control interface board inside the PLC controller housing, first push the fixing rod into the mounting slot. The spring column is compressed, pushing the power board and control interface board into the PLC controller housing. When the fixing rod moves to the fixing slot position, the spring column returns to its original shape, pushing the fixing rod into the fixing slot and protruding a section into the semi-circular silicone cover, thus achieving quick fixing of the power board and control interface board. The shapes of the fixing rod and slot are different for the power board and control interface board. When it is necessary to remove the power board and control interface board, press the semi-circular silicone cover to make the fixing rod exit from the fixing slot, and then the power board and control interface board can be pulled out from the PLC controller housing. This fixing method is simple to operate, requires no tools, facilitates the disassembly and maintenance of the power board and control interface board, and avoids damage to the component boards.

[0009] Preferably, a spring is installed on the cover, a buckle is installed at one end of the spring, and a slot is provided on the PLC controller housing, with the buckle slidably connected to the slot.

[0010] Using the above technical solution, when the cover is installed on the PLC controller housing, the spring is compressed. When the latch moves to the slot on the PLC controller housing, the spring returns to its original shape, pushing the latch into the slot, thus achieving a stable connection between the cover and the PLC controller housing. When maintenance or replacement of parts inside the PLC controller is required, pressing the latch causes it to slide out of the slot, making it easy to open the cover. This facilitates quick disassembly and assembly of the cover, and the operation is simple and requires no tools, improving maintenance efficiency.

[0011] Preferably, one end of the ventilation duct protrudes outside the housing cover, and a sealing ring is provided on the exposed section of the outer wall of the ventilation duct.

[0012] By adopting the above technical solution, the setting of the sealing ring ensures the sealing between the ventilation pipe and the ventilation duct when the ventilation pipe is inserted into the ventilation duct, and also ensures the stable connection between the ventilation pipe and the ventilation duct, preventing air leakage from affecting the heat dissipation effect.

[0013] Preferably, the external power supply cable on the heat sink is connected to the fan motor.

[0014] Using the above technical solution, the fan inside the heat sink is driven by an external power cord, ensuring that the fan generates sufficient airflow during operation and provides a stable heat dissipation effect for the PLC controller.

[0015] Preferably, the power board and the control interface board are connected by a connector, and the control interface board includes a control unit and a signal receiving and transmitting unit.

[0016] Using the above technical solution, the control unit of the control interface board is responsible for controlling and adjusting the PLC controller according to preset logic. The signal receiving and transmitting unit is responsible for communicating with external devices, transmitting and receiving data and instructions. The power supply board provides power to the PLC controller. The connector connection method also facilitates the disassembly, assembly, and maintenance of the power supply board and the control interface board, reducing maintenance costs and time.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The fan's rotation drives air into the heat sink through the air inlet. After passing through the filter, the filtered air enters the ventilation duct through the ventilation pipe, and then blows through the air outlet onto each component board inside the PLC controller, such as the power board and control interface board. This allows the air to circulate between each component board, effectively carrying away the heat generated by these components. Finally, the hot air is discharged from the PLC controller housing through the air outlet, forming a complete heat dissipation cycle. This prevents the PLC controller from overheating, which could lead to equipment failure or performance degradation, and improves the heat dissipation efficiency and effectiveness of the PLC controller.

[0019] 2. When it is necessary to fix the power board and control interface board inside the PLC controller housing, first push the fixing rod into the mounting slot. The spring column will be compressed, pushing the power board and control interface board into the PLC controller housing. When the fixing rod moves to the fixing slot position, the spring column returns to its original shape, pushing the fixing rod into the fixing slot and protruding a section into the semi-circular silicone cover, thus quickly fixing the power board and control interface board. The shapes of the fixing rod and slot are different for the power board and control interface board. When it is necessary to remove the power board and control interface board, press the semi-circular silicone cover to make the fixing rod exit from the fixing slot, and then the power board and control interface board can be pulled out from the PLC controller housing. This fixing method is simple to operate, requires no tools, facilitates the disassembly and maintenance of the power board and control interface board, and avoids damage to the component boards.

Install the heat sink 9 into the installation window 8 with screws. The fan 10 inside the heat sink 9 is driven by an external power supply, generating airflow. The rotation of the fan 10 drives the air to enter from the air inlet of the heat sink 9. After being filtered by the filter screen 11, dust and impurities are removed, ensuring that the air entering the PLC controller is clean. The filtered air enters the ventilation channel 16 through the ventilation pipe 17, and then blows through the air outlet 19 to each layer of component boards inside the PLC controller, such as the power board 3 and the control interface board 21, so that the air circulates between each layer of component boards, effectively carrying away the heat generated by these components. Finally, the hot air is discharged from the PLC controller housing 1 through the air outlet 18, forming a complete heat dissipation cycle. This prevents the PLC controller from overheating, which could lead to equipment failure or performance degradation, and improves the heat dissipation efficiency and effect of the PLC controller.

When it is necessary to fix the power board 3 and the control interface board 21 inside the PLC controller housing 1, first push the fixing rod 5 into the mounting slot 15. The spring column 4 will be compressed, pushing the power board 3 and the control interface board 21 into the PLC controller housing 1. When the fixing rod 5 moves to the fixing slot 6, the spring column 4 returns to its original shape, pushing the fixing rod 5 into the fixing slot 6 and protruding a section into the semi-circular silicone cover 7, thus achieving quick fixing of the power board 3 and the control interface board 21. The rod and slot of the power board 3 and the control interface board 21 have different shapes. When it is necessary to remove the power board 3 and the control interface board 21, press the semi-circular silicone cover 7 to make the fixing rod 5 exit from the fixing slot 6, and then the power board 3 and the control interface board 21 can be pulled out from the PLC controller housing 1. This fixing method is simple to operate, requires no tools, facilitates the disassembly and maintenance of the power board 3 and the control interface board 21, and avoids damage to the component boards.

A slot 13 is provided on the PLC controller housing 1, and the buckle 12 is slidably connected to the slot 13. When the cover 2 is installed on the PLC controller housing 1, the spring 14 is compressed. When the buckle 12 moves to the slot 13 on the PLC controller housing 1, the spring 14 returns to its original position, pushing the buckle 12 into the slot 13, thus achieving a stable connection between the cover 2 and the PLC controller housing 1. When it is necessary to maintain or replace parts inside the PLC controller, press the buckle 12 to slide it out of the slot 13, and the cover 2 can be easily opened. This facilitates quick disassembly and assembly of the cover 2, and the operation is simple and requires no tools, improving maintenance efficiency.

[0029] One end of the ventilation pipe 17 protrudes outside the housing cover 2, and a sealing ring 20 is provided on the exposed outer wall of the ventilation pipe 17. The sealing ring 20 ensures the sealing between the ventilation pipe 17 and the ventilation channel 16 when the ventilation pipe 17 is inserted into the ventilation channel 16, and also ensures the stable connection between the ventilation pipe 17 and the ventilation channel 16, preventing air leakage from affecting the heat dissipation effect.

[0030] The external power supply cable on the heat sink 9 is connected to the motor of the fan 10. The fan 10 inside the heat sink 9 is driven by the external power supply cable, ensuring that the fan generates sufficient airflow during operation and provides a stable cooling effect for the PLC controller.

[0031] The power supply board 3 and the control interface board 21 are connected via connectors. The control interface board 21 includes a control unit and a signal receiving and transmitting unit. The control unit of the control interface board 21 is responsible for controlling and adjusting the PLC controller according to preset logic.

After passing through the filter screen 11, dust and impurities are removed, ensuring that the air entering the PLC controller is clean. The filtered air enters the ventilation channel 16 through the ventilation pipe 17, and then blows through the air outlet 19 to each layer of component boards inside the PLC controller, such as the power board 3 and the control interface board 21, allowing air to circulate between each layer of component boards, effectively carrying away the heat generated by these components. Finally, the hot air is discharged from the PLC controller housing 1 through the air outlet 18, forming a complete heat dissipation cycle and avoiding... This method prevents PLC controller internal temperature from causing equipment failure or performance degradation, and improves the heat dissipation efficiency and effectiveness of the PLC controller.
