Description

[0002] The fixed flat of the carding machine is an important part of the carding machine. It is fixed and plays the role of pre-combing fibers, reducing the load on the working flat, and improving the parallel straightness of fibers. The fixed flat, also known as the front and rear combing plates of the cylinder, is usually installed on the front lower cover plate and the needle gate or the rear cover plate of the cylinder. It can increase the combing area of ​​the cylinder arc surface, so that the fibers can be pre-combed before entering the cylinder and flat combing area, making the combing more detailed. At the same time, the fixed flat can also supplement the combing of fibers combed by the cylinder and the benefit plate to further improve the quality of the fibers. In the fully fixed flat carding machine, the fixed flat replaces the traditional movable flat and cooperates with the cylinder to complete the combing function.

[0003] During the initial use of the current fixed cover, it is necessary to adjust the matching distance with the cylinder to improve the use effect of the fixed cover. However, currently the distance between the needle plate and the cylinder in the fixed cover is often adjusted by rotating the fixing bolts on the fixed cover, which is a cumbersome operation. After the fixed cover has been used for a period of time, it is necessary to clean the impurities such as short fluff adhered to the needle plate in the fixed cover and readjust it to ensure the normal use of the fixed cover.

Then, the connecting rod will drive the needle plate to move different distances inside the sliding hole, thereby adjusting the distance between the needle teeth on the needle plate and the cylinder.

[0022] 2. When the needle plate needs to be re-adjusted after being used for a period of time, the needle plate can be turned 180 degrees after approaching the rectangular block by setting structures such as magnetic springs, electric push rods and cavities, so as to facilitate the cleaning of short lint and impurities on the needle plate;

[0023] 3.

[0024] 4. During the rotation of the third conical wheel, the third conical wheel drives the round rod to rotate, so that the round rod drives the cam to rotate. During the rotation of the cam, the matching plate that slides against it drives the U-shaped frame to slide back and forth inside the fixed cover plate through the sliding plate, thereby increasing the operating range of multiple hollow rollers, thereby improving the cleaning ability of impurities such as short fluff on the needle plate, and facilitating the subsequent readjustment of the distance between the needle plate and the cylinder, so as to improve the quality of the needle plate combing process.

[0045] A method for adjusting a fixed flat plate adjustment structure for a carding machine, comprising the following steps:

[0046] S1. By starting the magnetic push rod 23, the movable end of the magnetic push rod 23 will drive the distance between the piston ring 19 and the side plate 20 to change, thereby changing the position of the connecting rod 21. Then, the connecting rod 21 will drive the needle plate 3 to move different distances inside the sliding hole 9, thereby adjusting the distance between the needle teeth on the needle plate 3 and the cylinder;

[0047] S2, the magnetic spring 27 is energized, and then the electric push rod 7 is turned on, so that the needle plate 3 continues to approach the rectangular block 17. When the rectangular block 17 moves to the end of the stroke, the magnetic spring 27 is deenergized, so that the rectangular block 17 drives the needle plate 3 to turn 180 degrees through the connecting rod 21;

[0048] S3, turn on the micro motor 5 and the electric telescopic plate 43, so that the hollow roller 46 can scrape off impurities such as short lint attached to the needle teeth on the needle plate 3 through multiple cylinders 47 during the rotation process.

[0049] In the present invention, when the user fixes the fixed frame 1 and the carding machine and then adjusts the distance between the needle plate 3 in the fixed cover plate 2 and the cylinder on the carding machine, the user turns on the magnetic push rod 23, the magnetic push rod 23 and the side plate 20 are fixedly connected, and the movable end of the magnetic push rod 23 and the piston ring 19 are fixedly connected. Then, when the movable end of the magnetic push rod 23 moves, the movable end of the magnetic push rod 23 will drive the distance between the piston ring 19 and the side plate 20 to change, and then change the position of the connecting rod 21. Then, the connecting rod 21 will drive the needle plate 3 to move different distances inside the sliding hole 9, and then adjust the distance between the needle teeth on the needle plate 3 and the cylinder.

[0050] After the needle plate 3 has been used for a period of time, impurities such as short fibers produced during the production process of the cotton carding machine adhere to the needle plate 3, which will affect the use effect of the needle plate 3. At this time, the needle plate 3 needs to be re-adjusted. At this time, the magnetic spring 27 is energized. After the magnetic spring 27 is energized, it shrinks a certain distance, which will drive the plug rod 28 and the slot 25 fixedly connected thereto to disengage from the limit position. Then, when the main shaft 16 rotates, it will not drive the rectangular block 17 to rotate.

[0051] Then, the electric push rod 7 is turned on, and the movable end of the electric push rod 7 drives the shaped plate 8 to slide to the left for a distance (such as Figure 4As shown, the U-shaped plate 8 will drive the first rack 10 and the box body 11 to move synchronously. The first rack 10 will drive the second gear 14 meshed with it to rotate. The second gear 14 will drive the second rack 13 meshed with it to move in the reverse direction for a certain distance. Then the second rack 13 will drive the sliding plate 12 to slide quickly and seal inside the box body 11, so that the sliding plate 12 will draw the hydraulic oil inside the cavity 18 into the box body 11 through the connecting pipe 15. Then the piston ring 19 will drive the connecting rod 21 to move upward for a certain distance through the magnetic push rod 23 and the side plate 20, making the needle plate 3 continuously approach the rectangular block 17, facilitating the subsequent flipping operation.

[0052] After the rectangular block 17 moves to the end of the stroke, at this time, the magnetic spring 27 is powered off. The magnetic spring 27 elongates and drives the insertion rod 28 to insert into the slot 25. When the U-shaped plate 8 drives the first rack 10 to continue moving, the first rack 10 will drive the rectangular block 17 to rotate 180 degrees through the second gear 14 and the main shaft 16. Then the rectangular block 17 will drive the needle plate 3 to flip 180 degrees through the connecting rod 21. At this time, the second rack 13 and the sliding plate 12 penetrate and slide for buffering.

[0053] Then, the electric telescopic plate 43 drives structures such as the U-shaped frame 42, the limiting rod 38, and the limiting holes to drive the L-shaped plate 31 and the vertical plate 30 to move downward synchronously, so that the third conical wheel 34 and the first conical wheel 29 are engaged. The micro motor 5 is started. The output end of the micro motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the first conical wheel 29 to rotate. The first conical wheel 29 drives the third conical wheel 34 meshed with it to rotate. The third conical wheel 34 drives the second conical wheel 33 meshed with it to rotate. Then the second conical wheel 33 will drive the spline shaft 32 fixedly connected to it to rotate. The spline shaft 32 drives a plurality of first bevel gears 41 keyed to it to rotate. Each first bevel gear 41 drives the second bevel gear 45 meshed with it to rotate. The second bevel gear 45 drives the circular tube 44 fixedly connected to it to rotate. Each circular tube 44 drives the hollow roller 46 fixedly connected to it to rotate. The cylinders 47 uniformly distributed and penetrated and fixed on the side wall of the hollow roller 46 will scrape off impurities such as short lint adhered to the needle teeth on the needle plate 3. And each rotary joint 48 is fixedly connected to the outside blower through an external connecting pipe. Then the blower can draw negative pressure inside the hollow roller 46 through the rotary joint 48 and the circular tube 44, so that the short lint and other impurities scraped off on the cylinder 47 are drawn into the hollow roller 46 through the suction pores 49 and then discharged to the outside through the rotary joint 48 for collection.

[0054] And during the rotation of the third conical wheel 34, the third conical wheel 34 drives the round rod 35 to rotate, so that the round rod 35 drives the cam 36 to rotate, and the cam 36 drives the U-shaped frame 42 to slide back and forth inside the fixed cover plate 2 through the electric telescopic plate 43 through the matching plate 37 that slides against it during the rotation, thereby increasing the operating range of the multiple hollow rollers 46, and then improving the cleaning ability of impurities such as short fluff on the needle plate 3, making it convenient to readjust the distance between the needle plate 3 and the cylinder to improve the quality of the needle plate 3 in the combing process.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
