[0002] The carding and combing equipment is a front spinning equipment composed of a cotton grabbing machine, an opening machine, a multi-bin cotton blending machine, a cotton cleaning machine, a cotton carding machine and the like, and is usually provided with a fan, a gold fire detector, a micro dust removing machine and the like, and the carding and combing equipment undertakes the production process from raw cotton to sliver.

[0003] The traditional manual cotton blending method is basically to pre-blend and then put into the carding and combing production line for production, so as to realize full mixing of multiple components. With the increasing requirement of market for the diversity of differentiated fabrics, the demand of textile enterprises for mixing of multiple varieties of raw materials is increasing, and the traditional manual cotton blending method cannot meet the production demand in terms of mixing precision and production efficiency.

[0004] In recent years, with the rapid development of blending market, the automatic weighing cotton blending equipment in the field of carding and combing is applied more and more widely, and is not suitable for continuous and automatic production of super multi-component (≥6) variety blending due to the influence of component number and proportion difference, and still needs to use the traditional manual cotton blending method for production, that is, manual pre-blending and then packaging, and then put into the conventional carding and combing production line.

[0005] The existing multi-component weighing cotton feeder is only suitable for blending of 6 or less fibers, and it is difficult to achieve blending of more than 10 fibers through process expansion, and the process expansion brings additional equipment use, increasing the equipment investment cost and land area.

[0006] In addition, the existing multi-component blending equipment is difficult to meet the user's demand in terms of blending precision and blending uniformity when used for blending of fibers with many varieties and large differences.

Summary of the Invention

[0011] To address the aforementioned problems in the prior art, this invention provides a multi-component blended spinning cleaning and carding system and production method, which is suitable for blended varieties with more than 10 fiber components. Moreover, the fiber material mixing method is reasonable, the blending fineness and uniformity are high, the cotton blending process is short, and continuous production can be basically achieved. The operation is flexible and convenient, and it has a wide range of applications.

[0012] The objective of this invention is achieved through the following technical solution: A multi-component blending and carding system includes a cotton grabber, a multi-bin blender, a cotton cleaner, a carding machine, and a control system. The system is characterized by having two large-bin fine blenders preceding the multi-bin blender. Each large-bin fine blender includes a frame and blending bins on the frame. The two ends of each blending bin are an inlet and an outlet, respectively. A tipping bucket is installed at the inlet for manual weighing and feeding. A circulating mixing device is installed inside each blending bin for the repeated mixing of raw materials. Two cotton grabbers are each connected to one large-bin fine blender. The two large-bin fine blenders are connected in parallel and then connected to one multi-bin blender. The cotton cleaner connected to the multi-bin blender is connected to multiple carding machines.

[0013] Improvements to the above technical solution: The cotton grabber is a disc-type cotton grabber, and a cotton condenser is installed on the top of the cotton mixing bin near the feed inlet. The cotton condenser is connected to the disc-type cotton grabber through a cotton conveying pipe, and automated production is achieved through disc-type cotton feeding.

[0014] Further improvements to the above technical solution: The circulating mixing device in the cotton blending bin includes, from the inlet end to the outlet end, a small flat curtain, an opening beater, a large flat curtain, a blending beater I, a blending beater II, a stripping beater, a corner nail curtain, a stripping roller, and a leveling roller. One end of the large flat curtain is located below the material drop end of the small flat curtain, and the other end of the large flat curtain is close to the lower end of the corner nail curtain. The stripping beater is located on the side of the corner nail curtain facing the inlet, the stripping roller is located on the side of the corner nail curtain facing the outlet, and the leveling roller is located above the corner nail curtain. The corner nail curtain is tilted. The corner nail curtain has two tilt angles to switch between cotton mixing and cotton output modes. The corner nail curtain is equipped with a tilting drive mechanism, which is controlled by the control system to tilt and swing the curtain. The upper end of the corner nail curtain tilts towards the feed inlet for cotton mixing mode, and the upper end tilts towards the outlet for cotton output mode. In cotton mixing mode, the upper half of the corner nail curtain is close to the cotton stripping beater. In cotton output mode, the top side of the corner nail curtain is close to the cotton stripping roller, and the top of the corner nail curtain is close to the cotton leveling roller.

[0015] Further improvements to the above technical solution: The tilting drive mechanism includes a screw, a drive motor, and drive components installed on the top of the cotton blending bin above the corner nail curtain; in the cotton blending mode, the angle between the corner nail curtain and the large flat curtain is 60°-75°; in the cotton discharging mode, the angle between the corner nail curtain and the large flat curtain is 105°-120°.

[0016] Further improvements to the above technical solution: The area above the large flat curtain in the cotton blending bin is divided into a first cotton blending zone, a second cotton blending zone, and a third cotton blending zone. The first cotton blending zone is used to receive raw materials falling from the small flat curtain. Two cotton blending beaters I are installed in the second cotton blending zone, and two cotton blending beaters II are installed in the third cotton blending zone. A top cover is installed above the first, second, and third cotton blending zones. A door is installed on the side wall of the cotton blending bin in the first cotton blending zone. Two opening beaters arranged vertically are installed above the material dropping end of the small flat curtain. The opening beaters are double-sided toothed opening beaters.

[0017] The present invention discloses a production method for the above-mentioned multi-component blended yarn cleaning and carding system, characterized in that the production method includes the following steps: Step 1: Weighing is performed manually or / and via the feeding module flat curtain weighing method configured in the large warehouse fine cotton blending machine. In the manual weighing method, the various fibers weighed in proportion are placed on the tipping bucket, and the tipping bucket flips the fibers through the feed port of the large warehouse fine cotton blending machine into the small flat curtain inside the blending bin. In the feeding module flat curtain weighing method, the raw materials grabbed by the disc cotton grabber are mixed into the cotton condenser through the cotton conveying pipe, and then enter the small flat curtain inside the cotton condenser. Step 2: After the opening beater opens the fibers, it throws them into the large flat curtain. The large flat curtain transports the fibers to the corner nail curtain position. At this time, the upper end of the corner nail curtain is tilted towards the outlet end and is in the cotton blending mode. The corner nail curtain carries the fibers up and they are separated by the stripping beater. The cotton blending beater I and cotton blending beater II then throw the fibers towards the end of the large flat curtain near the small flat curtain. This cycle is repeated to mix the fibers in the cotton blending chamber evenly. Step 3: After the fibers are mixed, the upper end of the corner nail curtain is tilted towards the feed inlet to enter the cotton blending mode. The corner nail curtain carries the fibers on the large flat curtain and conveys them to the multi-compartment cotton blending machine through the outlet of the large compartment fine cotton blending machine. During this process, the cotton equalization roller peels the excess fibers on the corner nail curtain into the cotton blending compartment to prevent the outlet pipe from being blocked. The cotton stripping roller peels the fibers on the corner nail curtain into the outlet of the large compartment fine cotton blending machine. Step 4: The fibers that have been evenly mixed by the large-bin fine blending machine are conveyed to the multi-bin blending machine for further mixing, and then conveyed to the carding machine after being opened by the cotton cleaning machine.

[0018] An improvement to the above technical solution: a single large-scale fine cotton blending machine is a non-continuous output device. When two large-scale fine cotton blending machines are blending the same variety, the two large-scale fine cotton blending machines alternately blend and output cotton to achieve continuous production of subsequent machines.

[0019] Another improvement to the above technical solution: a single large-scale fine cotton blending machine is a non-continuous output device. When two large-scale fine cotton blending machines blend different varieties, the two large-scale fine cotton blending machines can achieve alternating production of two varieties.

[0020] Compared with the prior art, the present invention has the following advantages and positive effects: 1. This invention is applicable to blended varieties with more than 10 fiber components. Moreover, the fiber material is mixed in a reasonable way, with high blending fineness and uniformity, short blending process, and can basically achieve continuous production. It is flexible and convenient to operate and has a wide range of applications. 2. The large-scale fine cotton blending machine of this invention can directly select manual weighing to feed raw materials, which is particularly suitable for small-batch orders and varieties with many mixed raw materials; it can also use cotton grabber 1 to feed raw materials, and weigh them through the flat curtain of the feeding module, which is particularly suitable for large-batch cotton blending production with a small variety of products. In this way, automated production can be achieved and production efficiency can be high; in addition, a combination of manual weighing and cotton grabber feeding can be used, which is suitable for situations where the proportion of one raw material is very large and the proportion of other raw materials is very small. For raw materials with a large proportion, feeding them with cotton grabber 1 can reduce the intensity of manual labor and improve production efficiency. Attached Figure Description

The cotton condenser 2.17 is connected to the disc-type cotton grabber through a cotton conveying pipe, and automated production is achieved through disc-type cotton feeding.

[0026] Furthermore, the aforementioned small flat curtain 2.3, opening beater 2.4, large flat curtain 2.6, blending beater I 2.7, blending beater II 2.8, stripping beater 2.9, corner nail curtain 2.10, stripping roller 2.13, and leveling roller 2.15 are all present. One end of the large flat curtain 2.6 is located below the material discharge end of the small flat curtain 2.3, and the other end of the large flat curtain 2.6 is close to the lower end of the corner nail curtain 2.10. The stripping beater 2.9 is positioned on the side of the corner nail curtain 2.10 facing the feed inlet, the stripping roller 2.13 is positioned on the side of the corner nail curtain 2.10 facing the outlet, and the leveling roller 2.15 is located above the corner nail curtain 2.10. The corner nail curtain 2.10 is tilted and oscillates, with two tilt angles to switch between blending and discharge modes.

[0027] The aforementioned corner nail curtain 2.10 is equipped with a tilting drive mechanism. The control system controls the tilting drive mechanism to drive the corner nail curtain 2.10 to tilt and swing. The upper end of the corner nail curtain 2.10 tilts towards the feed inlet to set it to cotton mixing mode, and the upper end of the corner nail curtain 2.10 tilts towards the outlet to set it to cotton discharge mode. In the cotton mixing mode, the upper half of the corner nail curtain 2.10 is close to the stripping beater 2.9. In the cotton discharge mode, the top side of the corner nail curtain 2.10 is close to the stripping roller 2.13, and the top of the corner nail curtain 2.10 is close to the even cotton roller 2.15.

[0028] Furthermore, the aforementioned tilting drive mechanism includes a lead screw, a drive motor, and drive components mounted on the top of the cotton blending bin above the corner nail curtain. In the cotton blending mode, the angle between the corner nail curtain 2.10 and the large flat curtain 2.6 ranges from 60° to 75°; in the cotton discharging mode, the angle between the corner nail curtain 2.10 and the large flat curtain 2.6 ranges from 105° to 120°.

[0029] Furthermore, the area above the large flat curtain 2.6 in the cotton blending bin is divided into a first blending zone, a second blending zone, and a third blending zone. The first blending zone is used to receive raw materials falling from the small flat curtain 2.3. Two blending beaters I 2.7 are installed in the second blending zone, and two blending beaters II 2.8 are installed in the third blending zone. A top cover 2.16 is installed above the first, second, and third blending zones. A door 2.5 is installed on the side wall of the blending bin in the first blending zone. Two vertically arranged opening beaters 2.4 are installed above the material dropping end of the small flat curtain 2.3. The opening beaters 2.4 are double-sided toothed opening beaters.

[0030] Specifically: an output component 2.12 is installed inside the outlet of the cotton blending bin, and a guardrail 2.1 is installed around the tipping bucket 2.2 at the feed inlet of the cotton blending bin.

[0031] See Figure 1 , Figure 2 An embodiment of the production method of the above-mentioned multi-component blended yarn cleaning and carding system of the present invention includes the following steps: Step 1: Weighing is performed manually or / and via the feeding module flat curtain of the large warehouse fine cotton blending machine. In the manual weighing method, the various fibers weighed according to the ratio are placed on the tipping bucket 2.2, and the tipping bucket 2.2 flips the fibers through the feed inlet of the large warehouse fine cotton blending machine onto the small flat curtain 2.3 inside the blending bin. In the feeding module flat curtain weighing method, the raw materials grabbed by the disc cotton grabber are mixed into the cotton condenser 2.17 through the cotton conveying pipe, and then enter the small flat curtain 2.3 inside the cotton condenser 2.17. Step 2: After the opening beater 2.4 opens the fibers, it throws them into the large flat curtain 2.6. The large flat curtain 2.6 conveys the fibers to the corner nail curtain 2.10. At this time, the upper end of the corner nail curtain 2.10 is tilted towards the outlet end and is in the cotton blending mode. The corner nail curtain 2.10 carries the fibers up and then they are peeled by the stripping beater 2.9, and then thrown by the cotton blending beater I 2.7 and cotton blending beater II 2.8 towards the end of the large flat curtain 2.6 near the small flat curtain 2.3. This cycle is repeated to mix the fibers in the cotton blending bin evenly.

[0032] Step 3: After the fibers are well mixed, the upper end of the corner nail curtain 2.10 is tilted towards the feed inlet to enter the cotton blending mode. The corner nail curtain 2.10 carries the fibers on the large flat curtain 2.6 and conveys them through the outlet of the large warehouse fine cotton blending machine 2 to the multi-warehouse cotton blending machine 3. During this process, the cotton equalization roller 2.15 peels the excess fibers on the corner nail curtain 2.10 into the cotton blending bin to prevent the outlet pipe from being blocked. The cotton stripping roller 2.13 peels the fibers on the corner nail curtain 2.10 into the outlet of the large warehouse fine cotton blending machine 2.

[0033] Step 4: After being evenly mixed by the large-compartment fine blending machine 2, the fibers are transported to the multi-compartment blending machine 3 for further mixing, and then loosened by the cotton cleaning machine 11 before being transported to the carding machine 12.

[0034] The first specific implementation method of the production method of the above-mentioned multi-component blending and combing system is as follows: a single large-scale fine blending machine is a non-continuous output device. When two large-scale fine blending machines are blending the same variety, the two large-scale fine blending machines alternately blend and output cotton to realize continuous production of subsequent machines.

[0035] Specifically: a screw 2.14 is installed outside the top of the cotton blending bin above the corner nail curtain 2.10; an output component 2.12 is installed inside the outlet of the cotton blending bin; and a guardrail 2.1 is installed around the tipping bucket 2.2 at the feed inlet of the cotton blending bin.

[0036] See Figure 1 , Figure 2 The present invention discloses a production method for the above-mentioned multi-component blended yarn cleaning and carding system, characterized in that the production method includes the following steps: Step 1: Weigh the various fibers according to the ratio by manual weighing or by weighing the feed module flat curtain configured in the large warehouse fine cotton blending machine 2. Place the weighed fibers on the tipping bucket 2.2. The tipping bucket 2.2 will turn the fibers into the small flat curtain 2.3 in the cotton blending bin through the feed port of the large warehouse fine cotton blending machine 2.

[0037] Step 2: After the opening beater 2.4 opens the fibers, it throws them into the large flat curtain 2.6. The large flat curtain 2.6 conveys the fibers to the corner nail curtain 2.10. At this time, the upper end of the corner nail curtain 2.10 is tilted towards the outlet end and is in the cotton blending mode. The corner nail curtain 2.10 carries the fibers up and then they are peeled by the stripping beater 2.9, and then thrown by the cotton blending beater I 2.7 and cotton blending beater II 2.8 towards the end of the large flat curtain 2.6 near the small flat curtain 2.3. This cycle is repeated to mix the fibers in the cotton blending bin evenly.

[0038] Step 3: After the fibers are well mixed, the upper end of the corner nail curtain 2.10 is tilted towards the feed inlet to enter the cotton blending mode. The corner nail curtain 2.10 carries the fibers on the large flat curtain 2.6 and conveys them through the outlet of the large warehouse fine cotton blending machine 2 to the multi-warehouse cotton blending machine 3. During this process, the cotton equalization roller 2.15 peels the excess fibers on the corner nail curtain 2.10 into the cotton blending bin to prevent the outlet pipe from being blocked. The cotton stripping roller 2.13 peels the fibers on the corner nail curtain 2.10 into the outlet of the large warehouse fine cotton blending machine 2.

[0039] Step 4: After being evenly mixed by the large-compartment fine blending machine 2, the fibers are transported to the multi-compartment blending machine 3 for further mixing, and then loosened by the cotton cleaning machine 11 before being transported to the carding machine 12.

[0040] The first specific production method: A single large-compartment fine blending machine 2 is a non-continuous output device. When two large-compartment fine blending machines 2 are blending the same variety, they alternate blending and outputting cotton to achieve continuous production for subsequent machines. Specifically, the two large-compartment fine blending machines 2 alternately blend and transport the cotton to the multi-compartment blending machine 3: that is, while one large-compartment fine blending machine 2 is blending cotton, the other large-compartment fine blending machine 2 has already finished blending and is transporting the fibers to the multi-compartment blending machine 3.

[0041] The second specific production method: a single large warehouse fine cotton blending machine 2 is a non-continuous output device. When two large warehouse fine cotton blending machines 2 blend different varieties, the two large warehouse fine cotton blending machines 2 realize the alternating production of the two varieties.

[0042] The large-scale fine cotton blending machine 2 of this invention can directly select manual weighing to feed raw materials, which is particularly suitable for small-batch orders and varieties with many mixed raw materials; it can also use the cotton grabber 1 to feed raw materials, and weigh them through the flat curtain of the feeding module, which is particularly suitable for large-batch cotton blending production with a limited variety of products. In this way, automated production can be achieved, resulting in high production efficiency. In addition, a combination of manual weighing and cotton grabber 1 can be used to feed raw materials, which is suitable for situations where the proportion of one raw material is very large and the proportion of other raw materials is very small. When the raw material with a large proportion is fed by the cotton grabber 1, the intensity of manual labor can be reduced and production efficiency can be improved.

[0043] The working principle of the Okura Fine Blending Machine 2 is as follows: it repeatedly mixes various fibers added in a specific ratio to achieve fine mixing and high uniformity. The mixture is then conveyed to subsequent equipment in the cleaning and carding line. The Okura Fine Blending Machine 2 is a non-continuous output device, with a single blending volume exceeding 300 kg. Due to its different mixing principle, the Okura Fine Blending Machine 2 can blend varieties with any fiber composition, showing a significant advantage, especially in multi-component blends.

[0044] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
