Description

Technical Field

[0001] This utility model relates to the field of cotton harvesting technology in textile machinery, specifically a filtration device for cotton harvesting and combing equipment in textile machinery. Background Technology

[0002] Combining cleaning and carding is a development trend in cotton spinning technology and a key indicator of the automation, continuity, and modernization of cotton spinning engineering. It's not simply a connection between cleaning and carding, but a recombination of the two under new conditions into a new production line. The application of combined cleaning and carding in textile processes is becoming increasingly widespread. Traditional spinning processes can no longer meet people's personalized needs, and combined cleaning and carding improves traditional spinning processes. In the processing of machine-picked cotton, due to the large differences in the maturity of the seed cotton during harvesting, it requires multiple cleaning, drying, and lint removal processes, leading to problems such as high impurity content, high short fiber content, and numerous defects. Strengthening the research on the process of combing machine-picked cotton in combined cleaning and carding is crucial to improving the combing effect and ensuring yarn quality. Spinning machine cotton cleaning and carding equipment often requires specialized filtration devices.

[0003] According to the authorized announcement number CN215050909U, a filtering device for cotton picking and carding equipment in textile machinery is disclosed, including a machine casing, a filter screen, and a door. A cotton suction machine is fixedly installed on the top of the machine casing, and a cotton inlet pipe is fixedly connected to the bottom of the cotton suction machine. A first rubber hose is fixedly installed on the side of the cotton inlet pipe, and a pipe head is fixedly connected to the bottom of the first rubber hose. A rolling shaft is fixedly installed inside the cotton outlet. This filtering device for cotton picking and carding equipment in textile machinery features a filter screen capable of secondary elastic filtration. A spring is installed at the bottom of the filter screen. When the cotton that has been sucked in falls onto the filter screen, it applies pressure to the filter screen, which causes the spring to be elastic, making the filter screen shake up and down. When there are a lot of impurities on the cotton, they will be shaken off and fall to the bottom plate. The shaken cotton will roll onto the filter screen below, thus achieving secondary filtration, improving the filtration capacity of the device, and making it less likely for impurities to remain on the cotton.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is found that although the filter screen of the aforementioned equipment can achieve secondary elastic filtration with the help of springs, that is, by using the gravity of the falling cotton to act on the filter screen, the spring elasticity drives the filter screen to shake up and down to separate impurities, it lacks an active vibration structure and relies solely on the spring force and the weight of the cotton to trigger vibration. When faced with cotton of different humidity and density, it is easy to have insufficient vibration intensity and incomplete impurity separation, making it difficult to adapt to diverse processing needs.

[0022] Reference Figure 1-3This is the first embodiment of the present invention, providing a filtering device for a cotton picking and combing equipment in a textile machine. The device includes a filtering mechanism 1, which comprises a filter box 101. The top of the filter box 101 has an inlet 102 connected to an external cotton suction machine. The bottom of the filter box 101 is open. A first receiving plate 103 is fixedly installed on the left side of the top of the filter box 101. The top of the first receiving plate 103 is movably connected to a first screen plate 104 via a hinge. A second receiving plate 105 is fixedly installed on the right side of the bottom of the filter box 101. The top of the second receiving plate 105 is movably connected to a second screen plate 106 via a hinge. The first screen plate 104 and the second screen plate 106 are... The filter box 101 is tilted and includes a vibration mechanism 2. The vibration mechanism 2 includes a rotating rod 21, which is located on the top of the first screen plate 104 and the top of the second screen plate 106. Rubber actuating rods 22 are fixedly connected to the left and right sides of the surface of the rotating rod 21 near the edges of the first screen plate 104 and the second screen plate 106. Springs 23 are fixedly connected to the front and rear sides of the top left side of the first receiving plate 103 and the front and rear sides of the top right side of the second receiving plate 105. The other ends of the springs 23 are fixedly connected to the bottom of the first screen plate 104 and the second screen plate 106, respectively. Rotating components 24 are fixedly connected to the front and rear sides of the surface of the rotating rod 21. A transmission mechanism 3 is located on the back of the filter box 101.

[0023] Specifically, by setting up a vibration mechanism 2, the rotating rod 21 and the rubber actuating rod 22 actively drive the screen plate to vibrate, which changes the existing device's method of relying solely on the elasticity of the spring 23 and the weight of the cotton to trigger vibration. This enhances the vibration intensity and can more thoroughly separate impurities in cotton with different humidity and density, adapting to diverse processing needs.

[0024] Furthermore, during screening, the transmission mechanism 3 drives the rotating rod 21 to rotate, and the rubber actuating rod 22 on the rotating rod 21 rotates accordingly, continuously actuating the first screen plate 104 and the second screen plate 106. At the same time, the spring 23 at the bottom of the first screen plate 104 and the second screen plate 106 cooperates with its movement, causing the first screen plate 104 and the second screen plate 106 to vibrate. The cotton undergoes two screenings on the vibrating first screen plate 104 and the second screen plate 106. Impurities fall onto the first impurity receiving plate 103 and the second impurity receiving plate 105 through the first screen plate 104 and the second screen plate 106. The filtered cotton is discharged from the bottom opening of the filter box 101. Example

[0025] In the second embodiment of this utility model, the rotating assembly 24 includes a bearing 241, which is fixedly connected to the front and rear sides of the surface of the rotating rod 21. The filter box 101 has a mounting hole 242 for use with the bearing 241, and the bearing 241 is fixedly installed inside the mounting hole 242.

[0026] Specifically, by setting the rotating component 24, the rotating rod 21 is ensured to rotate stably and smoothly, which improves the stability and reliability of the vibration mechanism 2, reduces wear during equipment operation, and extends the service life of the device.

[0027] Furthermore, in the rotating assembly 24, the bearing 241 is fixed to the front and rear sides of the surface of the rotating rod 21 and installed in the mounting hole 242 inside the filter box 101, providing support and positioning for the rotation of the rotating rod 21 and reducing friction and shaking when the rotating rod 21 rotates. Example

[0028] In the third embodiment of this utility model, the transmission mechanism 3 includes a transmission pulley 31, which is located on the back of the filter box 101. The transmission pulley 31 is fixedly connected to the rear side of the surface of the rear rotating rod 21. The surfaces of the two transmission pulleys 31 are connected by the same transmission belt 32. A drive assembly 33 is provided at the rear end of the rotating rod 21 at the top of the first screen plate 104.

[0029] Specifically, by setting up the transmission mechanism 3, the synchronous movement of the two rotating rods 21 is achieved, ensuring the coordination of the vibration of the first screen plate 104 and the second screen plate 106, so that the cotton is subjected to uniform force during the two filtration processes, improving the consistency and effect of filtration, while simplifying the drive structure and reducing equipment costs.

[0030] Furthermore, in use, the drive assembly 33 drives the top rotating rod 21 of the first screen plate 104 to rotate, and the transmission pulley 31 on the rear side of the rotating rod 21 rotates accordingly. Through the transmission belt 32, the transmission pulley 31 on the top rotating rod 21 of the second screen plate 106 is driven to rotate, thereby making the two rotating rods 21 rotate synchronously.

[0031] First, the operator starts the drive motor 332 via the control panel 7. The drive motor 332, acting as a power source, drives the rotating rod 21 at the top of the first screen plate 104 to rotate. Since a transmission pulley 31 is fixedly connected to the rear of the rotating rod 21 at the top of the first screen plate 104, and this transmission pulley 31 is connected to the transmission pulley 31 at the rear of the rotating rod 21 at the top of the second screen plate 106 via a transmission belt 32, the two rotating rods 21 rotate synchronously under the action of the transmission mechanism 3. Simultaneously, the bearings 241 on the front and rear sides of the rotating rod 21 are installed in the mounting holes 242 inside the filter box 101, providing stable support for the rotation of the rotating rod 21, reducing friction and shaking, and ensuring smooth operation. Next, an external cotton suction machine feeds cotton into the filter box 101 through the feed inlet 102 at the top of the filter box 101. The cotton first falls onto the inclined first screen plate 104. On screen 04, as the rotating rod 21 rotates, the rubber actuating rod 22 on its surface near the edge of the first screen plate 104 continuously actuates the first screen plate 104. At the same time, the spring 23 connected to the bottom of the first screen plate 104 and the top left side of the first impurity receiving plate 103 moves in coordination, causing the first screen plate 104 to vibrate. Under the vibration of the first screen plate 104, some impurities in the cotton fall through the screen plate onto the first impurity receiving plate 103, achieving preliminary filtration. Subsequently, the cotton that has been preliminarily filtered by the first screen plate 104 slides down the inclined first screen plate 104 onto the equally inclined second screen plate 106. At this time, the rubber actuating rod 22 on the surface of the rotating rod 21 near the edge of the second screen plate 106 also continuously actuates the second screen plate 106, and the spring 23 connected to the bottom of the second screen plate 106 and the top right side of the second impurity receiving plate 105 moves in coordination, causing the second screen plate 106 to vibrate. Under the vibration of the second sieve plate 106, the remaining impurities fall onto the second receiving plate 105, completing secondary filtration. Throughout the filtration process, the operator can visually observe the filtration status of the cotton inside the filter box 101 and the accumulation of impurities on the first and second receiving plates 103 and 105 through the transparent acrylic observation window 6. When the impurities accumulate to a certain amount, the operator can open the switch door 5 on the impurity discharge trough 4 to discharge the impurities from the filter box 101, preventing the accumulation of impurities from affecting the vibration of the sieve plate and the filtration effect. Finally, the cotton after two filtrations is discharged from the opening at the bottom of the filter box 101 and enters the subsequent processing stage. In addition, the operator can adjust the speed of the drive motor 332 through the control panel 7 according to the different conditions such as the humidity and density of the cotton, thereby changing the rotation speed of the rotating rod 21 and adjusting the frequency of the rubber actuating rod 22 to actuate the sieve plate, thus controlling the vibration intensity and frequency of the sieve plate to adapt to diverse processing needs, ensure thorough impurity separation, and guarantee the quality of subsequent yarn production.

[0032] In summary: By setting up a vibration mechanism 2, the rotating rod 21 and the rubber actuating rod 22 actively drive the screen plate to vibrate, changing the existing device's method of relying solely on the spring force 23 and the cotton's own weight to trigger vibration. During screening, the transmission mechanism 3 drives the rotating rod 21 to rotate, and the rubber actuating rod 22 on the rotating rod 21 rotates accordingly, continuously actuating the first screen plate 104 and the second screen plate 106. Simultaneously, the springs 23 at the bottom of the first screen plate 104 and the second screen plate 106 cooperate with its movement, causing the first screen plate 104 and the second screen plate 106 to vibrate. The cotton undergoes two screenings on the vibrating first screen plate 104 and the second screen plate 106, and impurities fall onto the first impurity receiving plate 103 and the second impurity receiving plate 105. The filtered cotton is discharged from the bottom opening of the filter box 101. This enhances the vibration intensity, enabling more thorough separation of impurities in cotton with different moisture and density, adapting to diverse processing needs, and solving the problem of insufficient vibration intensity and incomplete impurity separation caused by the existing device relying solely on the spring force and the cotton's own weight to trigger vibration, thus achieving the effect of auxiliary vibration.
