DETAILED DESCRIPTION

[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] In one embodiment, Figure 1-7 shown.

[0028] The present embodiment provides a cotton blending device for spinning colored spun yarn, which includes a general cabin 1, a feed port 2 is provided at the top of one end of the general cabin 1, a discharge port 3 is provided at the bottom of the other end of the general cabin 1, a first beater 4, a second beater 5, and a third beater 6 are provided in the general cabin 1, and the first beater 4, the second beater 5, and the third beater 6 are arranged in sequence from one end of the feed port 2 to one end of the discharge port 3, the second beater 5 corresponds to between the first beater 4 and the third beater 6, and is close to the bottom of the general cabin 1, and the third beater 6, the second beater 5, and the third beater 6 are arranged in sequence from one end of the feed port 2 to one end of the discharge port 3. The first beaters 4 are arranged in a triangle, and a first partition 7 is provided in the main cabin 1. The first partition 7 blocks the third beater 6 and the discharge port 3. A slot adjacent to the second beater 5 and the third beater 6 is provided in the middle of the first partition 7. A cotton board 8 facing the second beater 5 and the third beater 6 is installed on the first partition 7 through the slot. The main cabin 1 is divided into a mixing cabin 101 and a discharge cabin 102 by the first partition 7, and at the same time, an interconnected cross-material channel 103 is formed on the top of the mixing cabin 101 and the discharge cabin 102. An air duct 9 is provided in the general cabin 1. One end of the air duct 9 is horizontally extended and provided with a lower bent portion 10. The lower bent portion 10 is bent between the second beater 5 and the third beater 6. The pipe mouth direction of the lower bent portion 10 passes through between the second beater 5 and the third beater 6 and faces the cotton receiving plate 8, so that the ejected gas impacts the cotton receiving plate 8. A first beating rod 11 is fixed on the first beater 4 and the second beater 5. A second beating rod 111 is provided on the third beater 6. The length of the second beating rod 111 on the third beater 6 can be changed. When the second beating rod 111 rotates with the third beater 6 to contact the cotton receiving plate 8, it is compressed and shortened. When the second beating rod 111 rotates with the third beater 6 to enter the cross-material channel 103, it can be stretched and lengthened. The other end of the air duct 9 away from the lower bent portion 10 extends horizontally and communicates with the cross-material channel 103.

[0029] In the present embodiment, cotton balls of two or more colors are put into the mixing chamber 101 from the feeding port 2 during use. With the rotating action, the first beating rod 11 on the first beater 4 breaks the cotton balls once and opens the cotton, and then transfers them to the second beater 5 under the rotating action. The first beating rod 11 on the second beater 5 opens the cotton for the second time and then transfers them toward the third beater 6. When the cotton balls are transferred toward the third beater 6, a part of them directly crosses the cotton receiving plate 8 and is entangled by the second beating rod 111 on the third beater 6. After that, they are put into the discharging chamber 102 through the cross-material channel 103 by means of rotating belt and are finally discharged out of the discharging port 3. Another part of the cotton balls are blown by the gas discharged from the lower bent portion 10 and temporarily stay on the cotton receiving plate 8. In particular, a large amount of cotton balls that will continue to be entangled with the second beater 5 and the third beater 6 are blown to the cotton receiving plate 8 and temporarily stay there. When the third beater 6 rotates with the second beating rod 111 above until it contacts the cotton receiving plate 8, this part of the cotton balls will be scraped off. To the third beater 6, and then with the continued rotation of the third beater 6, it is brought into the cross-material channel 103. Since the second beating rods 111 are retractable, these second beating rods 111 will become longer due to inertia when they rotate into the cross-material channel 103, and the cotton wool is thrown from the cross-material channel 103 into the discharge chamber 102 by inertia, and finally discharged outward through the discharge port 3. In the present invention, only three beaters are provided, and the three beaters are distributed in a triangular pattern, thereby making the size of the total chamber 1 smaller than that of the prior art. In order to reduce the overall size of the equipment, the third beater 6, the second beater 5 and the first beater 4 in the present invention are arranged in a triangular shape. In order to make the triangular structure of the three beaters reasonably distributed, especially to make the third beater 6 at a high position, so that the cotton wool from the second beater 5 can be reasonably brought into the discharge chamber 102, the second beating rod 111 provided on the third beater 6 has the characteristic of being stretched and lengthened.

[0030] In one embodiment, Figure 1-7 shown.

[0031] The present embodiment provides a cotton mixing device for spinning colored yarn, wherein the specific structure of the second beating rod 111 is composed of a plurality of sleeves 112 fixed on the third beater 6 and a swinging rod 113 arranged in the sleeve 112, one end of the swinging rod 113 is inserted in the sleeve 112, and can be telescopically moved along the tube cavity of the sleeve 112, the other end of the swinging rod 113 is provided with a shoulder 114, a spring 115 is provided between the outer periphery of the swinging rod 113 and the tube cavity of the sleeve 112, one end of the spring 115 is connected to the inner end of the tube cavity of the sleeve 112, and the other end of the spring 115 is elastically connected to the shoulder 114 of the swinging rod 113. When the third beater 6 rotates with the upper part of the second beating rod 111 to contact the cotton receiving plate 8, the end of the swing rod 113 actually contacts the cotton receiving plate 8. Since the cotton receiving plate 8 is fixed on the first partition plate 7, when the end of the swing rod 113 contacts the cotton receiving plate 8, it will be blocked by the first partition plate 7. Under the blocking of the first partition plate 7, the swing rod 113 is forced to retreat into the sleeve 112. When the swing rod 113 retreats into the sleeve 112, the ring shoulder 114 is used to squeeze the spring 115, so as to force the spring 115 to be compressed and shortened in the sleeve 112. At the same time, the end of the swing rod 113 The end of the swing rod 113 will scrape off the cotton wool attached to the cotton receiving plate 8. As the third beater 6 continues to rotate, the end of the swing rod 113 will slide along the inner surface of the first partition plate 7 into the cross-material channel 103. At this time, the end of the swing rod 113 will no longer be compressed, and the spring 115 will release its elastic force and become longer. When the spring 115 releases its elastic force and becomes longer, the swing rod 113 will be ejected. When the swing rod 113 is ejected, an inertia force will be generated. The inertia force will act on the spring 115 in the reverse direction, so that the spring 115 forms a reverse buffer in the sleeve 112, and the reverse buffer is formed by the shoulder 114. The swing rod 113 is used to vibrate the swing rod 113, and the vibrating action of the swing rod 113 is used to swing the scraped cotton wool through the cross-material channel 103 and drop it into the discharge chamber 102. Since the air duct 9 is provided with two exhaust ports, one exhaust port corresponds to between the first beating rod 11 and the swing rod 113 after the lower bending portion 10 is bent downward, so the exhausted gas can blow the cotton wool remaining on the swing rod 113 and attach it to the cotton receiving plate 8, and can also blow the cotton wool remaining on the first beating rod 11 after the cotton is opened and scraped from the cotton receiving plate 8 to the cotton receiving plate 8. The former has a great influence on the cotton wool remaining after the cotton is opened. The cotton wool remaining on the swinging rod 113 is cleaned, and the latter blows the cotton wool remaining on the first beating rod 11 after opening the cotton to the cotton receiving plate 8. The purpose is to increase the delivery amount of the cotton wool from the cotton opened by the first beater 4 and the second beater 5 when it is transferred to the swinging rod 113 on the third beater 6. The purpose is also to increase the delivery amount of the cotton wool when it is put into the discharge chamber 102 through the swinging rod 113. Although the equipment is small in size, it can still meet the normal cotton opening and cotton discharging, so that after two or more cotton balls are put in, the cotton opening and mixing work can be completed through the cooperation of the above three beaters.

[0032] In this embodiment, each first beating rod 11 on the first beater 4 corresponds to between two first beating rods 11 on the second beater 5, and the first second beating rod 111 on the third beater 6 corresponds to between two first beating rods 11 on the second beater 5, that is, the beating rods on the three beaters are designed to cross each other. After the cotton ball is broken open by the first beating rod 11 on the first beater 4, it is taken by the first beating rod 11 on the second beater 5 and then transferred to the third beater 6 in the same cross-crossing manner by the second beating rod 111.

[0033] In the present embodiment, in order to enable the outer end of the swinging rod 113 to abut against the cotton receiving plate 8 so that the cotton wool blown onto the cotton receiving plate 8 can be reasonably scraped and released in the direction of the cross-material channel 103 as the inertial force generated during rotation, a hooking portion 116 for scraping the cotton wool is provided at the outer end of the annular shoulder 114. The hooking portion 116 is bent in the clockwise rotation direction of the third beater 6. When the swinging rod 113 rotates to the cross-material channel 103 and the cotton wool becomes longer due to the inertial force and is released toward the discharge chamber 102, the hooking portion 116 is downward at this time, and the cotton wool can smoothly fall in the direction of the discharge chamber 102.

[0034] In this embodiment, there are several air holes 81 evenly distributed on the cotton receiving plate 8, one end of the air hole 81 is connected to the cotton mixing chamber 101, and the other end is connected to the discharge chamber 102, and the air hole 81 is inclined toward the discharge port 3. When the pipe mouth of the lower bend 10 is exhausted, in addition to blowing most of the cotton wool after opening onto the cotton receiving plate 8, the excess gas will pass through the air holes 81 and be discharged into the discharge chamber 102. Since the cotton receiving plate 8 is breathable, it can be ensured that the cotton wool blown onto the cotton receiving plate 8 can be effectively attached to the cotton receiving plate 8, so that it can be scraped away by the subsequent rotating swinging rod 113.

[0035] In this embodiment, the first partition 7 is arc-shaped, the cotton receiving plate 8 is arc-shaped, and the degree of arc is consistent with that of the first partition 7. When the swing rod 11 rotates with the third beater 6 until it contacts the cotton receiving plate 8 and scrapes the cotton on the cotton receiving plate 8 and continues to rotate, the arc of the first partition 7 is used to form a smooth guide for the cotton and the end of the swing rod 113, and the swing rod 113 is gradually pressed into the sleeve 112, and at the same time, the spring 115 is forced to compress and shorten to store elastic force in the sleeve 112, so as to ensure that when the swing rod 113 leaves the first partition 7 and rotates into the cross-material channel 103, the spring 115 is instantly released in length, so that the swing rod 113 vibrates, and ensures that the cotton scraped on the hook part 116 is instantly dropped into the discharge chamber 102.

[0036] In this embodiment, a diverter plate 91 is provided in the air duct 9, and an interconnecting interface 12 is provided between the top of the general cabin 1 and the top of the air duct 9. There are two interfaces 12, which are symmetrically arranged on both sides of the diverter plate 91. Inclined surfaces 92 are provided at both ends of the air duct 9. One inclined surface 92 is provided on the pipe mouth of the lower bend 10 and is opposite to the cotton receiving plate 8, and the other inclined surface 92 is provided on the horizontal section of the air duct 9 and is opposite to the cross-material channel 103, and is communicated with the top of the discharge cabin 102. In actual use, it is necessary to install a fan on the top of the general cabin 1, and an exhaust duct is connected to each of the exhaust ports of the fan. The two exhaust ducts are respectively connected to the two interfaces 12. One exhaust channel acts between the second beater 5 and the third beater 6 to help blow the cotton wool attached to the two beaters after the cotton is opened onto the cotton receiving plate 8, and the other exhaust channel acts on the cross-material channel 103 to help the cotton wool on the swing rod 113 pass through the cross-material channel 103 and fall into the discharge cabin 102.

[0037] In this embodiment, a conveyor belt 13 is provided in the discharge chamber 102, and two upper and lower transmission rollers 14 are provided in the discharge chamber 102 through bearings. The two transmission rollers 14 are vertically arranged one above and one below. The conveyor belt 13 is transmission-connected to the two transmission rollers 14. The upper end of the conveyor belt 13 is adjacent to the cross-material channel 103 and is opposite to the second beating rod 111 movably connected to the third beater 6. The bottom end of the conveyor belt 13 extends vertically downward to the vicinity of the feed port 2. The discharge chamber 102 is provided with a shielding member on the conveyor belt. 13 and the second partition 15 between the cotton receiving plate 8, one end of the second partition 15 extends upward and is connected to the middle of the first partition 7, the other end of the second partition 15 extends downward and then extends to the bottom of the discharge port 3. When the cotton wool is put into the discharge chamber 102, it will adhere to the conveyor belt 13, and as the conveyor belt 13 is transferred downward and scraped by the scraper 16, it will finally be discharged out through the discharge port 3. The setting of the conveyor belt 13 can increase the discharge speed of the cotton wool according to the floating characteristics of the cotton wool.

[0038] In this embodiment, the outer end of the transmission roller 14 is connected to the outer ends of the first beater 4, the second beater 5, and the third beater 6 by a belt drive from the outside of the main cabin 1, and can also be connected by a transmission method such as gears. Regardless of the transmission connection method, a motor for driving their rotation will eventually be set outside the equipment or on the main cabin 1.

[0039] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
