Description

Technical Field

[0001] This utility model relates to the field of jacquard machine technology, and in particular to a jacquard machine filter back-blowing cleaning device. Background Technology

[0002] A jacquard machine is a type of textile machinery primarily used for weaving fabrics with complex patterns. This machine precisely controls the rise and fall of the warp yarns, allowing the weft yarns to interweave and form specific patterns or designs. During operation, the internal components of the jacquard machine generate heat, which is often dissipated by fans installed on the machine unit, along with filters to prevent dust and lint from being drawn in and affecting the core components.

[0003] Conventional jacquard machines often accumulate a lot of lint and other impurities on their filters after prolonged use, affecting their permeability and resulting in poor filtration performance. This prevents the air generated by the fan from passing through in a timely manner, affecting the heat dissipation of the unit. Furthermore, since the filter is located inside the unit, manually cleaning the lint and impurities on the filter is inconvenient, time-consuming, and affects the normal operation of the jacquard machine.

[0004] To address this, a reverse-blowing cleaning device for jacquard machine filters is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a back-blowing cleaning device for the filter screen of a jacquard machine, in order to solve the problems mentioned in the background art, where conventional jacquard machines often accumulate a lot of cotton lint and other impurities on the filter screen after prolonged use, affecting the permeability of the filter screen, resulting in poor filtration performance, and the inability of the air generated by the fan to pass through in time, affecting the heat dissipation of the unit. Furthermore, since the filter screen is located in the unit, it is inconvenient and time-consuming to manually clean the lint and impurities on the filter screen, thus affecting the normal use of the jacquard machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a jacquard machine filter back-blowing cleaning device, comprising a jacquard machine body, wherein an air channel is provided in the jacquard machine body, and a filter screen is fixedly installed in the air channel; the jacquard machine body is provided with a back-blowing cleaning component for cleaning lint and impurities on the surface of the filter screen, the back-blowing cleaning component includes a movable frame attached to the jacquard machine body for changing the air direction, a sealing plate is provided on the movable frame, the jacquard machine body is provided with a bent air duct, and the bent air duct is connected to the air channel, and the movable frame is provided with an upper channel and a lower channel.

[0007] Preferably, a detachable filter bag is connected to the upper channel, the filter bag is used to collect lint and impurities on the surface of the filter, and a fan is fixedly installed on the lower channel.

[0008] Preferably, a connecting plate is fixedly connected to the movable frame, and a limiting groove is provided on the jacquard machine body, with the connecting plate slidably connected in the limiting groove.

[0009] Preferably, a motor is fixedly installed on the jacquard machine body, and a threaded rod is fixedly connected to the output shaft of the motor, and the threaded rod is threadedly connected to the connecting plate.

[0010] Preferably, a spring is fixedly connected between the sealing plate and the movable frame, and a guide plate is fixedly installed on the movable frame, with the guide plate slidably connected to the sealing plate.

[0011] Preferably, an isolation plate for blocking the air passage is fixedly connected to the movable frame, and the isolation plate is slidably connected in the jacquard machine body.

[0012] Preferably, the bent air duct is rotatably connected to a cover plate for preventing backflow of wind, and the bent air duct is fixedly connected to an inclined block for limiting the opening angle of the cover plate.

[0013] The beneficial effects of this utility model are:

[0014] This invention, by setting up a reverse-blowing cleaning component, allows the movable frame to move downwards under the drive of a motor, causing the upper channel to replace the lower channel. The lower channel is connected to the bent air duct. Cooling air generated by the fan enters the bent air duct through the lower channel and reaches the air duct. Under the obstruction of the baffle plate, the cooling air is blown towards the inside of the filter screen and comes out from the outside, forming a reverse-blowing airflow. This cleans away lint and impurities on the outside of the filter screen without the need for manual disassembly of the filter screen for cleaning, improving cleaning efficiency and making the cleaning process quick and fast.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 7As shown in the figure, a specific embodiment of this utility model provides a jacquard machine filter back-blowing cleaning device, including a jacquard machine body 1, an air channel 2 in the jacquard machine body 1, and a filter 3 fixedly installed in the air channel 2; the jacquard machine body 1 is provided with a back-blowing cleaning component for cleaning lint and impurities on the surface of the filter 3. By setting the back-blowing cleaning component, lint and impurities adhering to the filter 3 can be cleaned, so that the filter 3 does not need to be manually disassembled for cleaning, improving cleaning efficiency and making the cleaning process quick and fast, preventing the filter 3 from clogging and affecting the cooling of the internal components of the jacquard machine body 1. The back-blowing cleaning component includes a movable frame 4 attached to the jacquard machine body 1 for changing the air direction, a sealing plate 5 on the movable frame 4, a bent air channel 6 in the jacquard machine body 1, and the bent air channel 6 connected to the air channel 2. The movable frame 4 has an upper channel 7 and a lower channel 8.

[0027] like Figures 1 to 7As shown, specifically, a fan 10 is fixedly installed on the lower channel 8. During normal use of the jacquard machine body 1, the cooling air generated by starting the fan 10 passes through the lower channel 8 and the filter screen 3. The filter screen 3 filters the cooling air, removing lint and other impurities. After passing through the filter screen 3, the cooling air enters the air channel 2. The air channel 2 is connected to the core components inside the jacquard machine body 1 that require cooling. Thus, the cooling air is blown onto the core components through the air channel 2 and cools them down. The jacquard machine body 1 also has a cooling air exhaust system. The channel system, which is existing technology, has a connecting plate 11 fixedly connected to the movable frame 4. A limiting groove 12 is formed on the jacquard machine body 1, and the connecting plate 11 is slidably connected in the limiting groove 12. A motor 13 is fixedly installed on the jacquard machine body 1, and a threaded rod 14 is fixedly connected to the output shaft of the motor 13. The threaded rod 14 is threadedly connected to the connecting plate 11. When the surface of the filter screen 3 needs to be cleaned after prolonged use, the motor 13 is started, driving the threaded rod 14 to rotate, thereby causing the connecting plate 11 to move downwards in the limiting groove 12. The connecting plate 11 drives the movable frame 4 to move downwards until the upper channel 7 on the movable frame 4 moves to the position of the lower channel 8 and stops moving, that is, the upper channel 7 is connected to the air duct 2. A spring 15 is fixedly connected between the sealing plate 5 and the movable frame 4. A guide plate 16 is fixedly installed on the movable frame 4, and the guide plate 16 is slidably connected to the sealing plate 5. During the downward movement of the movable frame 4, the sealing plate 5 on the movable frame 4 gradually moves downwards and contacts the bent air duct 6 at the bottom. Under the pressure of the reaction force of the bent air duct 6, the sealing plate 16 and the guide plate 16 are pressed together. As the movable frame 4 moves upward, the spring 15 contracts under force, generating a reaction force. Meanwhile, the bent air duct 6 gradually replaces the sealing plate 5 and connects with the movable frame 4. At this time, a connecting channel is formed between the bent air duct 6 and the lower channel 8 on the movable frame 4. An isolation plate 17 for blocking the air duct 2 is fixedly connected to the movable frame 4, and the isolation plate 17 is slidably connected in the jacquard machine body 1. As the movable frame 4 moves downward, the isolation plate 17 moves downward in the jacquard machine body 1 and enters the air duct 2, thereby forming an isolation effect on the air duct 2.

[0028] like Figures 1 to 7As shown, specifically, a cover plate 18 for preventing backflow of wind is rotatably connected to the bent air duct 6, and an inclined block 19 for limiting the opening angle of the cover plate 18 is fixedly connected to the bent air duct 6. When the fan 10 is restarted, the cooling air generated by the fan 10 enters the lower channel 8 and passes through the bent air duct 6. After entering the bent air duct 6, the cooling air blows towards the cover plate 18, causing the cover plate 18 to flip upward under the action of the wind force, thereby allowing the cooling air to enter the air duct 2. The cover plate 18 is limited by the inclined block 19. The opening angle is limited, allowing the cover plate 18 to reset under gravity and block the bent air duct 6 when the wind disappears. The cooling air entering the air duct 2 is then blocked by the baffle plate 17, allowing it to blow towards the inside of the filter screen 3. At this time, the lint and impurities adhering to the outside of the filter screen 3 are blown into the upper channel 7 by the cooling air. This entry into the upper channel 7 is due to the downward movement of the movable frame 4 during the process, forming a connection between the upper channel 7 and the air duct 2. The upper channel 7 is connected to a detachable filter bag 9, which collects lint and impurities from the surface of the filter screen 3. After entering the upper channel 7, the lint and impurities are blown into the filter bag 9. After further filtration, the lint and impurities are collected in the filter bag 9. After cleaning, the reverse drive motor 13 causes the movable frame 4 to move upwards and reset, thereby causing the lower channel 8 to move upwards and reconnect with the air duct 2. As the movable frame 4 moves upwards, the insulating plate 17 also moves, no longer isolating the air duct 2. The sealing plate... After gradually being freed from the pressure of the bent air duct 6, the frame gradually moves downward and resets under the reaction force of the spring 15. After returning to the initial state, the fan 10 can continue to generate cooling air that enters the lower channel 8, passes through the filter screen 3, and enters the air duct 2, blowing towards the internal components for cooling. During the movement of the movable frame 4, the cooling air generated by the fan 10 can change from entering the inner side of the filter screen 3 from the outer side to blowing outward from the inner side of the filter screen 3, forming a reverse blowing air, thereby blowing away the lint and impurities attached to the outer side of the filter screen 3.
