Description

Technical Field

[0001] This invention relates to the field of textile equipment, and in particular to a multi-opening uniform cotton feeding machine. Background Technology

[0002] Cotton feeders are used to open and mix wool fabrics. However, due to the accumulation and compression of wool fabrics in the storage bin, unevenness in yarn consistency can occur. As a result, the wool fabrics falling into the storage bin of the cotton feeder will also be unevenly mixed and have different densities. At the same time, when the existing cotton feeder is conveying wool fabrics, the inclined nail curtain randomly moves the wool fabrics near the curtain fabric of the storage bin upwards. This cannot guarantee the uniformity of the wool fabrics and can also easily cause problems such as the wool fabrics accumulating and clumping on the surface of the inclined nail curtain due to unsuitable conveying speed. Summary of the Invention

[0003] This invention aims to solve the above problems and provides a multi-opening uniform cotton feeding machine, the technical solution of which is as follows:

[0004] A multi-opening uniform cotton feeding machine includes a housing. A cotton inlet channel is provided at the top front end of the housing. Below the cotton inlet channel, a first opening device, a cotton storage bin, and a bottom flat curtain are arranged in sequence. An inclined nail curtain is inclinedly arranged at the rear of the bottom flat curtain in the transmission direction. The inclined nail curtain moves upward towards the side facing the bottom flat curtain. A cotton leveling roller and a cotton stripping roller are respectively arranged on the front and rear sides of the upper part of the inclined nail curtain. The cotton leveling roller and the cotton stripping roller rotate in opposite directions, and the cotton stripping roller rotates in the same direction as the inclined nail curtain. A cotton dropping chamber is provided below the cotton dropping roller. A cotton feeding roller is arranged in pairs and rotates relative to each other. A conveying curtain is arranged horizontally below the cotton feeding roller. The conveying direction of the conveying curtain is outward from the housing. The conveying speeds of the first opening device, the bottom flat curtain, and the inclined nail curtain are corresponding, so that the drop point height of the first opening device in the cotton storage bin is consistent, and the thickness of the material carried by the inclined nail curtain from the cotton storage bin is consistent.

[0005] Based on the above scheme, the first opening device includes a feeding roller, an opening roller, a cotton feeding plate, and an opening roller cover. The outer circumferential surface of the opening roller is provided with opening teeth. The feeding roller is located on the upper part of the opening roller. The feeding roller and the opening roller rotate in the same direction, and the linear velocity of the outer circumferential surface of the opening roller is greater than that of the outer circumferential surface of the feeding roller. The cotton feeding plate and the opening roller cover are both arc-shaped plates, and their opening directions are respectively facing the feeding roller and the opening roller. The upper and lower ends of the cotton feeding plate are respectively connected to the bottom of the side wall of the cotton inlet channel and the top of the opening roller cover. The cotton feeding plate is located on the lower side of the feeding roller, and the opening roller cover is located on the upper side of the opening roller.

[0006] Based on the above scheme, the distance between the lower part of the cotton feeding plate and the wool feeding roller is gradually reduced.

[0007] Preferably, it also includes a ventilation and lint removal device, which includes an air intake pipe, a fan and an air outlet pipe connected in sequence. The air intake of the air intake pipe is connected to the lint removal chamber and draws air from the lint removal chamber. The air outlet at the end of the air outlet pipe is connected to the inside of the slanted nail curtain and exhausts air into the slanted nail curtain.

[0008] Based on the above scheme, the lint removal chamber is enclosed by a filter screen, and the air intake is located on the outside of the filter screen.

[0009] Preferably, the air intake is located at the lower part of the shedding chamber, and the air outlet is located at the middle part of the slanted nail curtain.

[0010] Preferably, a wool storage sensor is provided on the wool storage bin to detect the height of the wool, and the wool storage sensor is set at the drop point of the first opening device in the wool storage bin.

[0011] Based on the above scheme, a horizontal slide rail and a vertical slide rail are provided on the housing. The horizontal slide rail is fixedly installed at the position of the wool storage bin in the horizontal direction, and the vertical slide rail is slidably installed on the horizontal slide rail in the vertical direction and moves along the horizontal slide rail. The wool storage sensor is slidably installed on the vertical slide rail and moves along the vertical slide rail.

[0012] Preferably, the housing is provided with a transparent observation window for entering the hair, an observation window for opening the hair, an observation window for storing the hair, and an observation window for falling the hair, which are respectively located at the positions of the hair entering channel, the first opening device, the hair storage chamber, and the falling hair cavity.

[0013] Based on the above scheme, a hair entry sensor is installed at the hair entry observation window, and a hair shedding upper limit sensor and a hair shedding lower limit sensor are installed at the hair shedding observation window.

[0014] The beneficial effects of this invention are as follows: A first opening device is added between the wool inlet channel and the wool storage bin, so that the wool with different densities in the storage bin is opened and mixed before falling into the wool storage bin layer by layer; by controlling the dropping speed of the first opening device and the conveying speed of the bottom flat curtain and the inclined nail curtain, the wool in the wool storage bin is conveyed with uniform thickness one after another. By laying the wool in the wool storage bin horizontally and picking it vertically, the wool is made evenly even in shape and color; the air in the wool dropping chamber is exhausted into the inclined nail curtain by the fan, and the inside of the inclined nail curtain is kept in a positive pressure state by the air supply, which blows the cotton lint from the edge of the curtain, effectively avoiding the problem of cotton lint entering the inside of the inclined nail curtain and causing entanglement. At the same time, a negative pressure environment is formed in the wool dropping chamber, which helps the wool at the stripping roller fall to the conveying curtain and be transported out of the cotton feeder, preventing the accumulation of wool lint from causing blockage.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] In the description of this invention, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "inner," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1 to 5 As shown, a multi-opening uniform cotton feeding machine includes a housing 10. A cotton inlet channel 22 is provided at the top front end of the housing 10. Below the cotton inlet channel 22, a first opening device, a cotton storage bin 41, and a bottom curtain 51 are arranged sequentially. The first opening device includes a feeding roller 31, an opening roller 32, a cotton feeding plate 33, and an opening roller cover 34. The outer circumferential surface of the opening roller 32 is provided with opening teeth. The feeding roller 31 is located above the opening roller 32. The feeding roller 31 and the opening roller 32 are connected... 2. The rotation direction is the same, and the linear velocity of the outer circumference of the opening roller 32 is greater than the linear velocity of the outer circumference of the feeding roller 31. The feeding plate 33 and the opening roller cover 34 are both arc-shaped plates, and their opening directions are respectively facing the feeding roller 31 and the opening roller 32. The upper and lower ends of the feeding plate 33 are respectively connected to the bottom of the side wall of the wool inlet channel 22 and the top of the opening roller cover 34. The feeding plate 33 is set on the lower side of the feeding roller 31, and the opening roller cover 34 is set on the upper side of the opening roller 32. The wool in the storage bin enters the wool inlet channel 22 after entering through the wool inlet 21, and enters between the feeding roller 31 and the opening roller 32 with the feeding plate 33. Then, as the opening roller 32 rotates, the wool is broken up by the opening teeth and falls down along the opening roller cover 34 into the wool storage bin 41, completing the first opening of the wool in the feeding machine. Preferably, the gap between the lower part of the feed plate 33 and the feed roller 31 gradually decreases, thereby improving the gripping effect of the feed plate on the wool.

[0025] A slanted nail curtain 52 is inclinedly arranged at the rear of the bottom flat curtain 51 in the transmission direction. The slanted nail curtain motor 55 is mounted on the housing 10. The slanted nail curtain 52 moves upward towards the side of the bottom flat curtain 51. A uniform roller 53 and a stripping roller 54 are respectively arranged on the front and rear sides of the upper part of the slanted nail curtain 52. The uniform roller 53 and the stripping roller 54 rotate in opposite directions, and the stripping roller 54 rotates in the same direction as the slanted nail curtain 52. A falling pile cavity 61 is arranged below the stripping roller 54. After the uniform roller 53 mixes the wool on the slanted nail curtain 52 evenly, the stripping roller 54 peels off the wool on the slanted nail curtain 52 and drops it into the falling pile cavity 61, completing the secondary loosening of the wool. A feeding roller 62 is provided at the lower part of the shedding chamber 61. The feeding rollers 62 are arranged in pairs and rotate relative to each other. A conveying curtain 63 is arranged horizontally below the feeding rollers 62. The conveying direction of the conveying curtain 63 is towards the outside of the housing 10. The wool falling from the shedding chamber 61 forms regular cotton strips after passing through the feeding rollers 62, and is then transported to the next process via the conveying curtain 63.

[0026] The conveying speeds of the first opening device, the bottom flat curtain 51, and the inclined nail curtain 52 correspond, so that the material drop point of the first opening device in the wool storage bin 41 is... Figure 2 The height of point C remains consistent, and the thickness of the material carried by the inclined nail curtain 52 from the wool storage hopper 41 is consistent, meaning that the amount of material carried each time is approximately [missing information]. Figure 2Below point B, where point B is the contact point between the upper edge of the wool in the wool storage bin 41 and the oblique nail curtain 52, the wool layered in the wool storage bin 41 is extracted in sheets sequentially along a direction parallel to the oblique nail curtain 52. By laying the wool horizontally and extracting it vertically, the wool on the oblique nail curtain 52 is conveyed in the manner of layered arrangement in the wool storage bin 31, ensuring uniform color mixing and even yarn count. The conveying speed of the first opening device, the bottom flat curtain 51, and the oblique nail curtain 52 can be achieved by visually observing the height and shape of the wool in the wool storage bin 41 and then adjusting the speed of each drive motor; alternatively, a wool storage sensor 43 can be installed on the wool storage bin 41 to detect the height of the wool. The wool storage sensor 43 is set at the drop point of the first opening device in the wool storage bin 41, and a sensor is installed on the housing 10 at the position corresponding to point B. By detecting the height and shape of the wool at points B and C, the speed of each motor can be determined to be appropriate, and then adjusted manually or automatically. Preferably, the housing 10 is provided with a horizontal slide rail 44 and a longitudinal slide rail 45. The horizontal slide rail 44 is fixedly installed at the position of the wool storage bin 41 in the horizontal direction, and the longitudinal slide rail 45 is slidably installed on the horizontal slide rail 44 in the vertical direction and moves along the horizontal slide rail 44. The wool storage sensor 43 is slidably installed on the longitudinal slide rail 45 and moves along the longitudinal slide rail 45. In this way, the position of the wool storage sensor 43 can be adjusted according to the actual production speed through the horizontal slide rail 44 and the longitudinal slide rail 45, so as to accurately observe the wool condition at the drop point C.

[0027] It also includes a ventilation and lint removal device, which comprises a suction pipe 74, a fan 71, and an exhaust pipe 75 connected in sequence. The suction port 73 of the suction pipe 74 is connected to the shedding chamber 61 and draws air from the shedding chamber 61. The exhaust port 76 at the end of the exhaust pipe 75 is connected to the interior of the oblique nail curtain 52 and exhausts air into the oblique nail curtain 52. The fan motor 72 drives the fan 71 to draw air from the shedding chamber 61 and exhaust it into the oblique nail curtain 52, creating a negative pressure environment in the shedding chamber 61, causing the wool to fall from the shedding chamber 61 and preventing blockage. A positive pressure environment is created inside the oblique nail curtain 52, causing air to be discharged outward from the gap between the oblique nail curtain 52 and the shell 10, while blowing away the cotton wool in that area, preventing the cotton wool from entering the interior of the oblique nail curtain 52 from the gap and getting tangled with the roller. Thus, the above functions can be completed through internal air circulation, avoiding the need for an external air source or external exhaust. Preferably, the shedding chamber 61 is enclosed by a filter screen 64, and the air inlet 73 is located on the outside of the filter screen 64 to prevent cotton lint from being sucked into the fan 71 or discharged into the oblique nail curtain 52. The air inlet 73 is located at the lower part of the shedding chamber 61, and the air outlet 76 is located in the middle of the oblique nail curtain 52, thereby improving the shedding efficiency and lint removal quality.

[0028] For easy observation, the housing 10 is provided with a transparent observation window 24 for entering the hair, an observation window for opening the hair, an observation window 44 for storing the hair, and an observation window for falling the hair. These are respectively located at the positions of the hair entry channel 22, the first opening device, the hair storage chamber 41, and the falling hair chamber 61. A hair entry sensor 23 is provided at the hair entry observation window 24, and a falling hair upper limit sensor 65 and a falling hair lower limit sensor 66 are provided at the falling hair observation window. The above sensors can be photoelectric sensors or other types of sensors.

[0029] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
