[0018] Compared with the prior art, the present invention has achieved the following technical effects:

[0019] The automatic cotton mixing machine of the present invention achieves the effect of cotton coming out simultaneously but not simultaneously by making the rotation speeds of cotton feeding rollers in different cotton bins different and the rotation speeds of opening beaters in different cotton bins different, and can realize front and back cross mixing after opening, thereby improving the mixing effect of cotton.

[0020] Furthermore, the speed of the opening beater is directly proportional to the speed of the cotton feeding roller in the same cotton bin. If the speed of the cotton feeding roller is fast, the speed of the opening beater is fast, and if the speed of the cotton feeding roller is slow, the speed of the opening beater is slow, so as to ensure the average opening point of the cotton, the fiber damage rate is extremely small, and the growth rate of cotton knots is basically zero.

[0021] Furthermore, when the opening beater rotates, cotton delivery wind can be generated through the blade to blow the opened cotton out through the cotton path, thereby ensuring smooth cotton discharge, and the cotton discharge process is stable and smooth.

[0022] Furthermore, after the cotton is sent into the cotton tube, it will fall into the cotton storage bin under the action of its own gravity, and there is no need to consume other energy to send the cotton into the cotton storage bin.

[0023] Furthermore, the feed port is arranged on the side of the automatic cotton mixing machine, the cotton is fed from the side, and the cotton falls vertically into the cotton storage bin, forming an effect of efficient cotton feeding with horizontal spreading and direct taking; at the same time, the feed port can be easily set larger, and there is a gap between two adjacent cotton feeding tubes, which can make the cotton feeding smooth without the worry of cotton hanging or blocking.

[0024] Furthermore, the exhaust air is discharged from the dust collecting hood above, and the dust collecting hood is located above the upper cotton tube, so it is an upper suction method. When the cotton is full, the passage between the dust collecting hood and the upper cotton tube will not be blocked, so the wind force will not change, solving the problem of unstable suction.

[0025] Furthermore, since the dust collecting hood area is small and the pipes are concentrated, the dust collecting effect is significant, and fine impurities, flying dust and short fibers can be removed in advance, making the quality more stable.

[0026] Furthermore, two rollers are arranged in each cotton bin to clamp the cotton downwards, which is stable and trouble-free. The roller speeds are configured differently, forming a front-to-back cross-mixing effect in which cotton is fed in at the same time and discharged at different times, doubling the dust removal effect.

[0027] Furthermore, in actual applications, the number of cotton bins can be adjusted according to needs, and the cotton bins can be modularly designed, which is conducive to users to optimize the modular configuration in advance and combine them at will. It can be simple and easy to make on the manufacturing side, save material preparation, do not take up space, and save money. It can also be increased or decreased at any time during use to adapt to changes in variety and output, which can achieve multiple goals at one stroke to improve output, quality and efficiency as well as save machine costs.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The purpose of the present invention is to provide an automatic cotton mixing machine to solve the problems existing in the above-mentioned prior art and improve the quality of cotton mixing.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1-Figure 6 As shown, this embodiment provides an automatic cotton mixing machine, including a feeding unit, a cotton mixing unit, a dust collecting hood 9 and a cotton outlet hopper 13.

[0040] Among them, the feeding unit includes a feeding port 1, a cotton collecting fan 2 and a cotton feeding tube 3, one end of the cotton feeding tube 3 is connected to the feeding port 1, the air outlet of the cotton collecting fan 2 is connected to the feeding port 1, and the cotton collecting fan 2 is used to blow the cotton at the feeding port 1.

[0041] The cotton mixing unit includes at least two cotton bins distributed along the first direction, a cotton inlet tube 8 is arranged above each cotton bin, and any two adjacent cotton inlet tubes 8 are connected through a connecting elbow 7; a cotton storage bin 18, a cotton feeding roller 10, an opening beater 11 and a cotton path are arranged in sequence from top to bottom in the cotton bin, and a cotton dropping port communicating with the corresponding cotton storage bin 18 is arranged at the bottom of the cotton inlet tube 8, the two cotton paths of any two adjacent cotton bins are connected, and all cotton paths form a total cotton path; a transmission shaft and two cotton feeding rollers 10 are arranged in each cotton bin, and each cotton feeding roller 10 is connected to the transmission shaft through gear transmission.

[0042] In this embodiment, the speeds of the cotton feeding rollers 10 in different cotton bins are different, and the speeds of the opening beaters 11 in different cotton bins are different. The speed of the opening beater 11 is proportional to the speed of the cotton feeding rollers 10 in the same cotton bin. If the speed of the cotton feeding rollers 10 is fast, the speed of the opening beater 11 is fast, and if the speed of the cotton feeding rollers 10 is slow, the speed of the opening beater 11 is slow, so as to ensure the average opening point of the cotton, the fiber damage rate is extremely small, and the growth rate of cotton knots is basically zero.

[0043] The dust hood 9 is arranged above all the cotton inlet tubes 8, and the top end of each cotton inlet tube 8 is communicated with the dust hood 9, and a filter screen 6 is arranged at the opening between the top end of the cotton inlet tube 8 and the dust hood 9. The filter screen 6 is used to prevent cotton from entering the dust hood 9. An air outlet is arranged on the dust hood 9, and the air outlet of the dust hood 9 is connected with the dust suction port of the central dust collection system through a pipeline. The central dust collection system adopts existing equipment. Under the action of the suction force provided by the central dust collection system, the air and dust in the cotton inlet tube enter the dust hood 9 and finally enter the central dust collection system through the pipeline.

[0044] The feeding end of the cotton discharge hopper 13 is connected with the cotton discharge end of the main cotton channel. The cotton discharge hopper 13 is provided with a cotton discharge port 5. The other end of the cotton feeding tube 3 is connected with one end of the cotton inlet tube 8 close to the cotton discharge hopper 13 through a curved tube 4, and the cotton feeding tube 3 and all the cotton inlet tubes 8 form a cotton feeding channel.

[0045] In this embodiment, a first driving device is also included, and a driving sprocket and a driven sprocket are arranged on the transmission shaft. The driving sprocket on the transmission shaft and the driven sprocket on the adjacent transmission shaft are driven by a chain; the first driving device is used to be connected to one of the transmission shafts through a chain transmission mechanism; in this embodiment, the first driving device adopts a motor. When the first driving device drives one of the transmission shafts to rotate through the chain transmission mechanism, since the adjacent transmission shafts are connected together, the other transmission shafts will also rotate accordingly, thereby driving all the cotton feeding rollers 10 to rotate together. It should be noted that by making different driven sprockets have different diameters and numbers of teeth, the transmission ratio between two different transmission shafts is different, so that the rotation speeds of different transmission shafts are different, so that the rotation speeds of the cotton feeding rollers 10 in different cotton bins are different. In addition, in actual applications, the scheme for achieving different rotational speeds of the cotton feed rollers 10 in different cotton bins is not limited to the above-mentioned method of the present application. For example, the rotational speeds of the cotton feed rollers 10 in different cotton bins can be different by equipping different cotton bins with motors to drive the cotton feed rollers 10, as long as the rotational speeds of the cotton feed rollers 10 in different cotton bins can be different.

[0046] In this embodiment, a second driving device is also included, and a driven pulley is provided on the rotating shaft of each opening beater 11, and the diameters of the driven pulleys on different opening beaters 11 are different. A driving pulley is fixed on the output shaft of the second driving device, and a transmission belt is wound around the driving pulley and all the driven pulleys. The second driving device uses a motor. In addition, in practical applications, the scheme for achieving different rotation speeds of the opening beaters 11 in different cotton bins is not limited to the above-mentioned method of the present application. For example, different cotton bins can also be equipped with motors to drive the opening beaters 11, so that the rotation speeds of the opening beaters 11 in different cotton bins are different, as long as the rotation speeds of the opening beaters 11 in different cotton bins can be different.

[0047] In this embodiment, the cotton feeding roller 10 is evenly provided with 6 cotton feeding claws 101 along the circumferential direction to ensure that the cotton in the cotton storage bin 18 can be clamped and fed downward smoothly.

[0048] In this embodiment, the main body 111 of the opening beater 11 is in the shape of a rectangular column, and the cross-section of the main body 111 is square. A blade 112 is fixedly provided on each of the four circumferential edges of the main body 111. The angle between the blade 112 and the side wall of the main body 111 is 135°. A plurality of T-shaped teeth are provided at one end of each blade 112 away from the main body 111. When the opening beater 11 rotates, cotton delivery wind can be generated through the blade 112 to blow the opened cotton 12 out through the cotton path, thereby ensuring smooth cotton discharge, and the cotton discharge process is stable and smooth.

[0049] In this embodiment, a cotton drop observation port 14, an exhaust port and a cotton duct observation port 16 are provided on the side wall of the cotton bin. The cotton drop observation port 14 is located below the cotton drop port, an exhaust net 17 is provided at the exhaust port, and the cotton duct observation port 16 is located on one side of the cotton duct.

[0050] In this embodiment, an inspection port is further provided on the cotton bin, and an inspection door 15 is provided on the inspection port. When repair or maintenance is needed, the inspection door 15 is opened and the internal parts are repaired or maintained through the inspection port.

[0051] It is worth mentioning that in actual application, the number of cotton bins can be adjusted according to needs, and the cotton bins can be modularly designed, which is conducive to users to optimize the modular configuration in advance and combine them at will. It can be simple and easy to make, save material preparation, do not take up space, and save money on the manufacturing side. It can also be increased or decreased at any time during use to adapt to changes in its variety and output, which can achieve multiple goals at one stroke to improve output, quality and efficiency and save machine costs. For example, two cotton bins can be combined into one module (such as Figure 6 As shown in FIG. 1 , in addition to integrating two cotton bins, this module is also provided with a motor and electric control bin 19, an electric control unit 20 and a motor 21. The motor 21 is used to drive the cotton feeding roller 10 or the opening and beating hand 11 to rotate. It should be noted that although two cotton bins are provided in this module, only one cotton path observation port 16 is provided, and the cotton path observation port 16 is located between the two cotton bins. Naturally, except for Figure 6 In addition to the combination form, any other forms of combination can be made, such as combining three or more cotton bins into one module, and assembling different modules to obtain the final automatic cotton mixing machine. Of course, a single cotton bin can also be made as a module.

[0052] The working principle of the automatic cotton mixing machine in this embodiment is as follows:

[0053] The cotton is manually put into the feed port 1, and the cotton at the feed port 1 is blown into the cotton inlet tube 8 through the cotton feeding tube 3 under the action of the cotton collecting fan 2. In the first cotton inlet tube 8, part of the cotton falls into the cotton storage bin 18 of the first cotton bin under the action of its own weight, and the other cotton enters the cotton inlet tube 8 of the second cotton bin, and part of the cotton falls into the cotton storage bin 18 of the second cotton bin under the action of its own weight, and so on, until the remaining cotton enters the cotton inlet tube 8 of the last cotton bin, and falls into the cotton storage bin 18 of the last cotton bin under the action of its own weight. The blown air of the cotton collecting fan 2 is discharged through the dust collecting hood 9, and the dust collecting hood 9 will play a role in collecting dust; the dust collecting hood 9 is located above the upper cotton tube, so it is an upper suction mode, and the opening between the dust collecting hood 9 and the upper cotton tube will not be blocked when the cotton is full, so the wind force will not change, solving the problem of unstable suction;

[0054] After the cotton falls into the cotton storage bin 18, it will be sent to the bottom of the cotton feeding roller 10 under the action of the cotton feeding roller 10, and then the rotating opening beater 11 will loosen the cotton sent down. While the opening beater 11 rotates, it can generate cotton feeding wind through the blade 112 to blow the loosened cotton 12 out through the cotton channel, thereby ensuring smooth cotton discharge, and the cotton discharge process is stable and smooth; the loosened cotton 12 in the entire cotton discharge channel will enter the cotton discharge bucket 13 and be discharged through the cotton discharge port 5.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
