The control frame is driven by the threaded rod to move up and down in the cotton conveying pipeline, so that the space, capable of conveying cotton, in the cotton conveying pipeline is changed, the number of passing cotton flows is reduced through friction between the control frame and the inner wall of the cotton conveying pipeline, but the airflow conveying speed is not changed, and the carding machine at the rearmost end can obtain sufficient cotton. After the control frame ascends, the pressure plate descends relatively, the abutting block is extruded out of the control frame, the abutting plate on the abutting block pops up under the action of the first spring and abuts against the inner wall of the cotton conveying pipeline, and the higher the control frame moves upwards, the higher the pressure between the abutting plate and the inner wall of the cotton conveying pipeline is, the higher the pressure between the abutting plate and the inner wall of the cotton conveying pipeline is. Therefore, the purpose of protecting the control frame and the inner wall of the cotton carding pipeline attached to the control frame is achieved. The inclined plates, the telescopic rods and the sliding grooves are arranged, so that the inclined plates abut against the inner wall of the cotton conveying pipeline all the time to form inclined planes, and conveying of the cotton flow is facilitated.

Description

Technical Field

[0001] The utility model relates to the technical field of cotton flow control of a cotton carding machine, in particular to a cotton flow control device for a cotton yarn carding machine. Background Art

[0002] At present, the cotton flow control of the carding machine transports cotton through the cotton conveying pipeline: the first carding machine connected to the cotton flow control pipeline of the carding machine lacks the relevant methods to actively increase the cotton falling, and all depends on the automatic falling of cotton under the action of airflow. If the cotton flow speed (that is, the air flow speed) is reduced, the machine at the end cannot provide enough cotton; if the cotton demand of the last machine is met, the cotton drop of the first carding machine is passively reduced. The pipeline related to the first carding machine cannot be modified. The modification methods such as turning, sinking, and side pressure will cause uneven cotton flow speed, affecting the normal cotton use of other machines behind the cotton flow control of the carding machine.

[0003] The existing cotton flow control of the carding machine mainly relies on adjusting the cotton feeding amount of the cotton cleaning equipment and the wind speed of the cotton conveying fan to ensure that the cotton reaches the last carding machine. To ensure that each carding machine can drop the same cotton, it is mainly solved by adjusting the negative pressure of the upper cotton box and the size of the cotton box pressure relief port. Since the cotton needs to reach the last carding machine, the wind speed must be increased, so that the cotton of the first carding machine is not easy to fall. If the carding machine of a line is to be opened normally, the quality of the first and last carding machines can only be sacrificed. Therefore, it is necessary to design a cotton flow control device for a cotton yarn carding machine. Utility Model Content

[0004] Based on this, it is necessary to provide a cotton flow control device for a cotton yarn carding machine to address the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a cotton flow control device of a cotton yarn carding machine, including a frame, a cotton conveying pipeline and a mounting plate, the frame is rotatably connected with a threaded rod, a control frame is installed on the mounting plate, the control frame slides in the cotton conveying pipeline, the threaded rod is threadedly connected to the control frame, two inclined grooves are provided on the control frame, the inclined grooves are arranged oppositely, an abutment block is slidably connected in the inclined groove, an abutment groove is provided on the abutment block, an abutment plate is slidably connected in the abutment groove, a spring is installed in the abutment groove, the spring is connected to the abutment plate, one end of the threaded rod is rotatably connected with a pressure block, and the pressure block and the abutment block are arranged in coordination.

[0006] Preferably, a slide groove is provided in the control frame, a slider is slidably connected in the slide groove, a telescopic rod is installed on the slider, an inclined plate is hinged on the control frame, the output end of the telescopic rod is hinged to the inclined plate, and one end of the inclined plate hinged to the control frame is rounded.

[0007] Preferably, two limit plates are installed on the control frame, and the limit plates are located on both sides of the pressure block and abut against the pressure block.

[0008] Preferably, a second spring is installed on the control frame, and one end of the second spring is connected to the abutment block.

[0009] Preferably, fixed blocks are installed on both sides of the cotton conveying pipeline, and a fixed rod is installed on the mounting plate, and the fixed rod is slidably connected to the fixed block.

[0010] Preferably, a rotation driving device is installed on the frame, and the output end of the rotation driving device is drivingly connected to the threaded rod.

[0011] Preferably, a mounting opening is provided on the top of the rack, and a limit strip installed on the cooling fan control frame is installed in the mounting opening, and the limit strip is matched with the abutment plate.

[0012] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0013] The threaded rod drives the control frame to move up and down in the cotton conveying pipe, thereby changing the space in the cotton conveying pipe that can convey cotton. The friction between the control frame and the inner wall of the cotton conveying pipe reduces the amount of cotton flowing through, but the air flow conveying speed remains unchanged, so that the cotton carding machine at the rear end can also get enough cotton.

[0014] After the control frame rises, the pressure plate drops relatively, thereby squeezing the abutment block out of the control frame from the inclined slot, and then the abutment plate on the abutment block pops out under the action of spring 1 and abuts against the inner wall of the cotton conveying pipe. The more the control frame moves up, the greater the pressure between the abutment plate and the inner wall of the cotton conveying pipe through the inclined slot, thereby protecting the control frame and the inner wall of the cotton combing pipe to which it fits;

[0015] By setting the telescopic rod sliding in the slide groove, when the inclined plate is raised or lowered by the control frame, the inclined plate always abuts against the inner wall of the cotton conveying pipe to form an inclined surface, thereby facilitating the conveyance of the cotton flow and avoiding the cotton flow from getting stuck.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] See also Figures 1 to 5 The embodiment of the present application provides a cotton flow control device for a cotton yarn carding machine, including a frame 1, a cotton conveying pipe 2 and a mounting plate 101. The frame 1 is rotatably connected with a threaded rod 3, and a control frame 4 is installed on the mounting plate 101. The control frame 4 slides in the cotton conveying pipe 2 and abuts against the inner wall of the cotton conveying pipe 2. The threaded rod 3 is threadedly connected to the control frame 4. The control frame 4 is provided with two inclined grooves 5, which are arranged opposite to each other. An abutment block 6 is slidably connected in the inclined groove 5, and an abutment groove 7 is provided on the abutment block 6. An abutment plate 8 is slidably connected in the abutment groove 7. A spring 9 is installed in the abutment groove 7, and the spring 9 is connected to the abutment plate 8. One end of the threaded rod 3 is rotatably connected with a pressure block 10, and the pressure block 10 is arranged in conjunction with the abutment block 6.

[0024] In this embodiment, the threaded rod 3 on the control frame 1 is rotated so that the control frame 4 threadedly connected to the threaded rod 3 slides up and down in the cotton conveying pipe 2, so that the cotton flow can only pass through the gap between the control frame 4 and the cotton conveying pipe 2, thereby reducing the number of cotton flows passing through, and achieving the purpose of controlling the cotton flow; in the process of the control frame 4 gradually rising, the thrust of the airflow on it also gradually increases. When the control frame 4 rises, the pressure block 10 at one end of the threaded rod 3 rotatably connected to the threaded rod 3 descends relative to the control frame 4, so that the pressure block 10 squeezes the abutment block 6, causing it to slide out of the control frame 4 from the inclined slot 5. Through the inclined setting of the inclined slot, the higher the control frame 4 rises, the smaller the distance between the abutment block 6 and the inner wall of the cotton conveying pipe 2 is, so that the abutment plate 8 is squeezed out of the abutment slot 7 by the spring 19 which is always in a compressed state, and abuts against the inner wall of the cotton conveying pipe 2. The smaller the distance between the abutment block 6 and the inner wall of the cotton conveying pipe 2, the greater the pressure of the spring 19 on the abutment plate 8, thereby protecting the control frame 4 and the cotton conveying pipe 2 abutting against the control frame 4 on the other side of the airflow direction.

[0025] In some embodiments, in order to facilitate the transportation of cotton flow, a slide groove 11 is set in the control frame 4, and a slider 12 is slidably connected in the slide groove 11. A telescopic rod 13 is installed on the slider 12. An inclined plate 14 is hinged on the control frame 4. The output end of the telescopic rod 13 is hinged to the inclined plate 14, and one end of the inclined plate 14 hinged to the control frame 4 is rounded. The telescopic rod 13 is hinged with the inclined plate 14 hinged on the control frame 4, so that its inclination angle is limited to a certain extent, and the inclined plate 14 is limited by its own gravity, so that the end that is not hinged to the control frame 4 is always in contact with the inside of the cotton conveying pipe 2, thereby forming an inclined surface, which cooperates with the chamfer setting on the side of the airflow direction of the top of the control frame 4, so that the cotton flow will not be stuck by the control frame 4, and when the control frame 4 descends, the collision between the telescopic rod 13 and the inner wall of the cotton conveying pipe 2 enables the slider 12 to drive the telescopic rod 13 to move upward in the slide groove 11; the rounded corner setting ensures that when the inclined plate 14 rotates, one side of it is always in contact with the control frame 4, thereby preventing cotton from entering the gap between the inclined plate 14 and the control frame 4.

[0026] In some embodiments, in order to prevent the pressure block 10 rotatably connected to the threaded rod 3 from rotating, two limit plates 15 are installed on the control frame 4 . The limit plates 15 are located on both sides of the pressure block 10 and abut against the pressure block 10 .

[0027] In some embodiments, in order to facilitate the retraction of the abutment block 6 after being squeezed and ejected by the pressure block 10 , a second spring 16 is installed on the control frame 4 , and one end of the second spring 16 is connected to the abutment block 6 .

[0028] In some embodiments, in order to facilitate the protection of the threaded rod 3, fixed blocks 17 are installed on both sides of the cotton conveying pipe 2, and a fixed rod 18 is installed on the mounting plate 101, and the fixed rod 18 is slidably connected to the fixed block 17.

[0029] In some embodiments, in order to facilitate driving the threaded rod 3 , a rotation drive device 19 is installed on the frame 1 . The rotation drive device 19 may be a servo motor, and the output end of the rotation drive device 19 is drivingly connected to the threaded rod 3 .

[0030] In some embodiments, in order to prevent cotton from entering the control frame 4 through the gap between the abutment block 6 and the control frame 4 , a limit strip 20 is installed on the control frame 4 , and the limit strip 20 is matched with the abutment plate 8 .
