The multi-bin cotton mixing machine mainly consists of a cotton inlet fan 1, a cotton distribution channel 2, a cotton storage bin 3, a first motor 4, a cotton feeding roller 501, a cotton opening beater 502, a frame 6, a second motor 7, a cotton conveying flat curtain 8 and an electrical control system. During operation, the raw material enters the cotton distribution channel 2 from the cotton inlet through the cotton inlet fan 1. Under the control of the electrical control system, the bin cover valve on the upper part of the cotton storage bin 3 is opened and closed in sequence to complete the bin filling action one by one. The bin filling time is affected by the volume and quantity of the cotton storage bin 3. The larger the volume and the more the quantity, the longer the bin filling time.

[0004] At the same time, the important role of the cotton mixer is to mix multiple raw materials. In the prior art, the raw materials are mixed by the time difference of the cotton grabbing machine "feeding one bin by one and outputting at the same time". After the two raw materials grabbed by the cotton grabbing machine enter the multi-bin cotton mixer, it can only improve the mixing degree between the fibers of the two raw materials to a certain extent, and cannot achieve accurate mixing of the two raw materials in a certain proportion.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The core of the utility model is to provide a multi-bin cotton mixing machine, which adopts a multi-cotton distribution channel design, reduces the cotton storage bins connected by a single cotton distribution channel, reduces the time required for cotton filling, and improves work efficiency; and different raw materials can be filled into different cotton distribution channels, and the cotton distribution ratio of different raw materials can be accurately controlled according to the ratio of the number of cotton storage bins connected by different cotton distribution channels.

[0040] Another core of the utility model is to provide a cotton mixing production line including the above-mentioned multi-bin cotton mixing machine, which can solve the same technical problem.

[0041] Please refer to Figure 2 , Figure 2 A multi-bin cotton mixing machine, comprising:

[0042] At least two cotton storage bins 3, with a cotton outlet assembly 5 provided at the outlet of the cotton storage bins 3;

[0043] At least two cotton distribution channels 2, each of which is connected to at least one cotton storage bin 3;

[0044] The cotton conveying flat curtain 8 is used for receiving the cotton discharged from the cotton storage bin 3 .

[0045] By setting multiple cotton dispensing channels 2 for synchronous cotton filling, compared with the design of only one cotton dispensing channel 2 in the prior art, the time required for cotton filling is effectively reduced, the cotton mixing efficiency is improved, and each cotton dispensing channel 2 can be filled with raw materials of different components respectively, so as to achieve accurate mixing of multiple raw materials;

[0046] In some embodiments, two cotton dispensing paths 2 are designed, and the ratio of the number of cotton storage bins 3 corresponding to the two cotton dispensing paths 2 can be 1:1, 1:2, 1:3, 1:4, 1:9, 2:3, 3:7, etc. The ratio of the number of cotton storage bins 3 corresponding to the two cotton dispensing paths 2 is designed according to the required mixing ratio; when two cotton dispensing paths 2 are used, and the ratio of the number of corresponding cotton storage bins 3 is 1:1, the two cotton dispensing paths 2 are filled with cotton at the same time, and the time required for filling cotton is saved by 50% compared with the prior art;

[0047] There are also designs of three, four, and five cotton distribution channels 2, and the number of cotton storage bins 3 corresponding to the cotton distribution channels 2 is still designed according to the mixing ratio of different component raw materials to meet production needs;

[0048] The cotton discharging assembly 5 is mainly used for uniformly discharging the raw materials in the cotton storage bin 3. Its structure is varied, mainly in the form of rollers, to hold and peel the internal fibers, to avoid the accumulation of raw materials at the outlet of the cotton storage bin 3 and cause the outlet to be blocked;

[0049] The cotton conveying flat curtain 8 is fixedly installed on the frame 6 below the cotton storage bin 2. Its function is to receive the cotton discharged from the cotton storage bin 3. After the raw materials in the cotton storage bin 3 are discharged through the cotton discharge assembly 5, they are spread flat on the upper layer of the cotton conveying flat curtain 8. The raw materials from different cotton storage bins 3 are stacked in layers to achieve the purpose of mixing cotton.

[0050] In some embodiments, a bin cover valve 301 is provided at the connection point between the cotton storage bin 3 and the cotton distribution channel 2, and the cotton distribution channel 2 is connected to at most one cotton storage bin 3 at a time by controlling the opening and closing of the bin cover valve 301;

[0051] like Figure 2 As shown, the cotton distribution channel 2 is arranged above the cotton storage bin 3, and a bin cover valve 301 is arranged at the cotton inlet of the cotton storage bin 3. When the bin cover valve 301 is opened, the cotton distribution channel 2 is connected with the cotton storage bin 3, and when the bin cover valve 301 is closed, the cotton distribution channel 2 is not connected with the cotton storage bin 3. During the cotton filling process, at most one group of bin cover valves 301 is in the open state at a time, that is, at most one group of cotton storage bins 3 is connected with the cotton distribution channel 2, thereby realizing cotton filling bin by bin, ensuring that each cotton storage bin 3 stores raw materials of different time periods, thereby improving the mixing effect of the raw materials.

[0052] A plurality of cotton storage bins 3 are connected in parallel and connected to the cotton distribution path 2. When one of the bin cover valves 301 is opened, the corresponding cotton storage bin 3 is connected to the cotton distribution path 2 and blocks the cotton distribution path 2 on the downstream side of the bin cover valve 301.

[0053] In some embodiments, the mounting shaft of the bin cover valve 301 is located between two groups of cotton storage bins 3. When the bin cover valve 301 is opened, the cotton distribution channel 2 is divided into two sections at the opened bin cover valve 301. The upstream side is a connecting area capable of filling cotton, and the downstream side is a blocked closed area. The cotton storage bin 3 corresponding to the opened bin cover valve 301 is in the connecting area, that is, the cotton storage bin 3 can be filled with cotton, while the cotton storage bin 3 in the closed area cannot be filled with cotton even if the bin cover valve 301 is opened. Therefore, the cotton inlet of the cotton storage bin 3 at the most downstream may not be provided with a bin cover valve 301.

[0054] Meanwhile, when only one cotton storage bin 3 is provided corresponding to one cotton distribution channel 2 , the cotton storage bin 3 also does not need to be provided with a bin cover valve 301 .

[0055] In some embodiments, a cotton feeding fan 1 is connected in series in the cotton feeding channel 2;

[0056] During the cotton filling process, positive pressure is often used to blow the raw materials into the cotton distribution channel 2. Therefore, a cotton feeding fan 1 can be integrated in the cotton distribution channel 2. However, in some embodiments, an external cotton feeding fan 1 is used to blow the raw materials into the cotton distribution channel 2. The principle is the same.

[0057] like Figure 2 As shown, the cotton discharging assembly 5 includes:

[0058] Cotton discharge roller 501, two cotton discharge rollers 501 are arranged in a pair of rollers, and are used for stripping and balancing cotton;

[0059] The cotton opening beater 502 is used to open the cotton layer. The cotton opening beater 502 is arranged directly below the two cotton outlet rollers 501 and is arranged parallel to the cotton outlet rollers 501;

[0060] In addition to mixing raw materials, the cotton mixer also has a certain ability to loosen the cotton layer. The circumferential surface of the cotton discharge roller 501 has many protrusions. When the cotton discharge roller 501 rotates, the protrusions on its surface can hook the fibers in the raw materials and bring the raw materials out of the cotton storage bin 3. The speed of its rotation affects the speed of cotton discharge. Therefore, by adjusting its rotation speed, the mixing ratio of the raw materials in the corresponding cotton storage bin 3 in the product can be changed. The structure and working principle of the cotton discharge roller 501 are all existing technologies and will not be described in detail here.

[0061] The cotton opening beater 502 is mainly used to loosen the cotton layer, and its working effect is affected by its own rotation speed and cotton discharge speed. Therefore, in general design, the cotton opening beater 502 and the cotton discharge roller 501 are driven separately. However, in some implementations, the cotton opening beater 502 and the cotton discharge roller 501 are driven together. Both schemes have their own advantages and disadvantages. The former is convenient for controlling and regulating the working effect, but the number of motors needs to be increased, which increases the cost. The latter cannot independently control the cotton discharge speed and cotton opening effect, but has a simple structure and low cost.

[0062] In some embodiments, each set of cotton discharge rollers 501 is provided with a first motor 4 for individual driving;

[0063] Each cotton opening beater 502 is provided with a second motor 7 for independent driving;

[0064] That is, the cotton discharge speed and cotton opening effect of each cotton storage bin 3 can be controlled individually without being affected by other cotton storage bins 3. The cotton discharge speed of different cotton storage bins 3 can be adjusted to change the ratio of different raw materials. At the same time, the rotation speed of the cotton opening beater 502 can be adjusted to adapt to the cotton discharge speed generated by different rotation speeds of the cotton discharge roller 501 to ensure the cotton opening effect. However, this design requires adding a larger number of motors, which increases the cost significantly. It is only suitable for the production of small batches and multiple ratios of products.

[0065] In other embodiments, all the cotton discharge rollers 501 are driven by the same first motor 4;

[0066] All the cotton opening beaters 502 are driven by the same second motor 7;

[0067] In this design, the number of motors can be controlled to a minimum and the cost is lowest, but the rotational speeds of all cotton discharge rollers 501 are the same or the rotational speed ratio is fixed, that is, the cotton discharge speeds of all cotton storage bins 3 are consistent or the ratio is fixed. During the production process, it is impossible to achieve flexible adjustment of the cotton mixing ratio by differentiating the cotton discharge speeds, and is suitable for large-scale fixed-ratio product production.

[0068] In other embodiments, all the cotton delivery rollers 501 corresponding to the same cotton distribution path 2 are driven by the same first motor 4;

[0069] All the cotton beaters 502 corresponding to the same cotton distribution path 2 are driven by the same second motor 7;

[0070] All the cotton discharging rollers 501 under the same cotton distributing path 2 are driven uniformly, which ensures that the discharging speed of raw materials of the same component is consistent. The proportion of raw materials of different components can be adjusted by adjusting the speed difference of the cotton discharging rollers 501 under different cotton distributing paths 2. Compared with the designs in the first two embodiments, the number of motors is related to the number of cotton distributing paths 2, the overall cost is controllable, and it is suitable for the production of products in various modes and batches.

[0071] In some embodiments, Figure 2 As shown, the cotton storage bin 3 is arranged vertically, the top is connected to the cotton distribution channel 2, the cotton outlet assembly 5 is arranged at the bottom, and the cotton conveying flat curtain 8 is arranged below all the cotton storage bins 3;

[0072] By adopting a vertically arranged cotton storage bin 3, the raw materials inside can fall naturally under the action of gravity, and the raw materials after passing through the cotton discharging component 5 can fall naturally to the surface of the cotton conveying flat curtain 8 under the action of gravity, which can effectively simplify the internal design of the cotton storage bin 3; in some embodiments, due to the space limitation of the equipment, a horizontal cotton storage bin 3 is adopted, and a conveying component needs to be set inside it to transfer the raw materials at the cotton inlet to the cotton outlet. The internal structure of the cotton storage bin 3 is complicated, but it can still play its original role.

[0073] In some embodiments, there are ten cotton storage bins 3 arranged in parallel, and the cotton distribution path 2 includes a first cotton distribution path 201 and a second cotton distribution path 202; one of the cotton storage bins 3 is connected to the second cotton distribution path 202, and the remaining nine cotton storage bins 3 are connected to the first cotton distribution path 201;

[0074] like Figure 2 As shown, the left arrow is the first cotton feeding direction, the top arrow on the right is the second cotton feeding direction, and the bottom arrow on the right is the feeding direction of the cotton conveying flat curtain 8;

[0075] The multi-bin cotton mixing machine is provided with a total of ten cotton storage bins 3, which are bin 10, bin 9, bin 8, bin 7, bin 6, bin 5, bin 4, bin 3, bin 2 and bin 1 from left to right, wherein bin 10 to bin 2 are connected with the first cotton distribution channel 201, and bin 1 is connected with the second cotton distribution channel 202; and each cotton storage bin 3 from bin 10 to bin 3 is provided with a bin cover valve 301 at the cotton inlet, and bin 2 and bin 1 are not provided with a bin cover valve 301 at the cotton inlet, and are in a directly connected state; the ratio of the cotton storage bins 3 corresponding to the two cotton distribution channels 2 is 9:1; when filling cotton, the first cotton distribution channel 201 fills cotton from the first cotton distribution channel 202 from the second cotton distribution channel 202.

[0076] In actual production, the two raw materials fed by the multi-bin cotton mixer in this embodiment are output at the same time, and the mixing ratio of the output raw materials is about 9:1, and the proportion of the small proportion of raw materials is about 11%; by analogy, when the two-way cotton feed corresponds to the cotton storage bin 3 with a quantity ratio of 8:2, the output raw material mixing ratio is 8:2; when the two-way cotton feed corresponds to the cotton storage bin 3 with a quantity ratio of 7:3, the output raw material mixing ratio is 7:3; when the two-way cotton feed corresponds to the cotton storage bin 3 with a quantity ratio of 6:4, the output raw material mixing ratio is 6:4; when the two-way cotton feed corresponds to the cotton storage bin 3 with a quantity ratio of 5:5, the output raw material mixing ratio is 5:5.

[0077] In addition to the multi-bin cotton mixing machine disclosed in the above embodiments, the utility model also provides a cotton mixing production line including the multi-bin cotton mixing machine, such as Figure 3 As shown, the upstream end of the cotton blending channel 2 is connected in series with a cotton opener 9, and the cotton feeding of the two groups of cotton blending channels 2 does not interfere with each other. For the structures of other parts of the cotton blending production line, please refer to the prior art and will not be described in detail herein.

[0078] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0079] The above is a detailed introduction to the multi-bin cotton blending machine provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
