Description

Technical Field

[0001] The present application relates to the technical field of spinning, and in particular to a cotton cleaning device. Background Art

[0002] In the blowing and carding of the spinning industry, Figure 1 As shown, the cotton cleaning machine is located between the multi-bin cotton mixing machine and the carding unit, and further opens and removes impurities from the cotton bundles delivered by the multi-bin cotton mixing machine, and then delivers the processed cotton bundles to the carding unit. At present, the cotton cleaning machine usually includes a machine body and several parts such as a conveying fan 01, a cotton box 02, an exhaust mesh plate 03, a feeding roller, a beater, and an impurity removal work area arranged in the machine body.

[0003] As the output of the cleaning and combing process increases, the number of bins in the multi-bin cotton mixing machine is often not less than ten. In order to transfer the raw materials in each cotton channel of the multi-bin cotton mixing machine to the cotton cleaning machine in time, the conveying fan 01 is required to provide a larger air volume and a higher air pressure. The larger the air volume and the higher the air pressure of the conveying fan 01, the greater the exhaust wind speed of the exhaust mesh plate 03 above the cotton box 02. This requires that the dust filter negative pressure is relatively increased to transfer the airflow above the cotton box 02 in time and realize the air-fiber separation. However, the greater the exhaust wind speed of the exhaust mesh plate 03, the mesh of the exhaust mesh plate 03 will be blocked with fibers, affecting the air-fiber separation, and then causing larger cotton blocks to be blown into the beater area, causing the beater to be blocked. In addition, if the wind pressure at the cotton cleaning machine outlet is large, the airflow impact force is large when the cotton flow falls, and the raw materials will tumble violently in the cotton box 02, which will not only cause photoelectric malfunctions, but also produce more ropes and cotton knots, affecting the yarn index.

[0004] From the above, it can be seen that too high or too low wind pressure and air volume of the cotton cleaner will affect the operating effect of the cotton cleaner and is not conducive to the quality of the yarn. This is in irreconcilable contradiction with the increasing output requirements of the current cleaning and carding process. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the structure of a cotton cleaning machine provided by the prior art; Figure 2 A schematic diagram of the structure of the cotton cleaning device provided in the embodiment of the present application; Figure 3 A schematic diagram of the structure of a cotton cleaning machine provided in an embodiment of the present application; Figure 4 A schematic diagram of the structure of the dust stick group provided in the embodiment of the present application; Figure 5 A schematic diagram of the structure of the rigid supporting plate provided in an embodiment of the present application.

[0030] Please refer to Figure 2 and Figure 3 The present application provides a cotton cleaning device, including a cotton mixing machine 1, a cotton cleaning machine 2 and a conveying fan 3; a working chamber 21 is provided in the cotton cleaning machine 2, and no power equipment such as a fan that can be specifically used to exhaust gas is provided in the working chamber 21. This type of power equipment can be regarded as a wind conveying device, that is, no wind conveying device is provided in the working chamber 21; the working chamber 21 includes a cotton cleaning machine inlet 211 and a cotton cleaning machine outlet 212, and the cotton cleaning machine inlet 211 and the cotton cleaning machine outlet 212 are respectively connected to the conveying fan 3; all the conveying fans 3 are arranged outside the cotton cleaning machine 2.

[0031] In this embodiment, the cotton mixer 1 is located upstream of the cotton cleaner 2 and can supply cotton materials to the cotton cleaner 2; the cotton cleaner 2 is located downstream of the cotton mixer 1 and is used to break up and loosen the cotton materials supplied by the cotton mixer 1; the cotton cleaner inlet 211 and the cotton cleaner outlet 212 of the cotton cleaner 2 are respectively connected to the conveying fan 3. It can be seen that the cotton mixer 1, the conveying fan 3, the cotton cleaner 2 and the conveying fan 3 are connected in sequence.

[0032] The cotton cleaner inlet 211 and the cotton cleaner outlet 212 are connected to the conveying fan 3 respectively. If the conveying fan 3 connected to the cotton cleaner inlet 211 is regarded as the first conveying fan 3, and the conveying fan 3 connected to the cotton cleaner outlet 212 is regarded as the second conveying fan 3, then the first conveying fan 3 and the second conveying fan 3 are respectively located upstream and downstream of the cotton cleaner 2. The first conveying fan 3 is located upstream of the cotton cleaner 2, and is also located between the cotton mixer 1 and the cotton cleaner 2; the first conveying fan 3 can not only suck cotton materials from the cotton mixer 1 to move the cotton materials in the cotton mixer 1 toward it, but also can send air toward the cotton cleaner 2 to make the cotton materials continue to move from the cotton mixer 1 toward the cotton cleaner 2. The second conveying fan 3 is located downstream of the cotton cleaner 2, and can suck cotton materials from the cotton cleaner 2 to move the cotton materials in the cotton cleaner 2 out of the cotton cleaner outlet 212.

[0033] Usually, any two adjacent ones of the cotton mixer 1, the first conveying fan 3, the cotton cleaner 2 and the second conveying fan 3 can be connected by pipelines, which can be referred to Figure 1 A rigid pipe is provided between any two adjacent ones of the cotton mixing machine 1, the first conveying fan 3, the cotton cleaning machine 2 and the second conveying fan 3, and the cotton material moves along each rigid pipe in sequence under the drive of the first conveying fan 3 and the second conveying fan 3.

[0034] As can be seen from the above, all the conveying fans 3 of the cotton cleaning equipment can guide the cotton material to flow through the cotton mixer 1 and the cotton cleaning machine 2 in sequence, meeting the conveying requirements of the cotton material. Since all the conveying fans 3 are arranged outside the cotton cleaning machine 2, the operator can easily and quickly adjust the power of the conveying fans 3, so that the power of the conveying fans 3 can be flexibly and accurately matched to the installation relationship, operation characteristics and output requirements of the relevant devices.

[0035] The cotton cleaning device provided in the present application is further described below in conjunction with the accompanying drawings and implementation methods.

[0036] The cotton cleaner 2 is provided with an operating chamber 21. In some embodiments, the operating chamber 21 includes not only a cotton cleaner inlet 211 and a cotton cleaner outlet 212, but also a cotton inlet passage 213, an exhaust passage 214, a cotton processing chamber 215 and a cotton outlet passage 216. Figure 2 and Figure 3, the cotton inlet channel 213, the exhaust channel 214, the cotton processing chamber 215 and the cotton outlet channel 216 are connected in sequence; wherein, the cotton cleaner inlet 211 is connected to the cotton inlet channel 213, and the cotton outlet channel 216 is connected to the cotton cleaner outlet 212. When the cotton mixer 1 supplies cotton material to the cotton cleaner 2, the cotton material in the cotton mixer 1 enters the cotton inlet channel 213 from the cotton cleaner inlet 211, and the cotton material is broken up and loosened in the cotton cleaner 2 and then flows out of the cotton cleaner outlet 212 from the cotton outlet channel 216.

[0037] In the above embodiment, the cotton inlet channel 213, the exhaust channel 214 and the cotton processing chamber 215 form a bend; the cotton processing chamber 215 extends downward to guide the cotton material to flow downward; part of the channel wall around the exhaust channel 214 is an exhaust mesh plate 22, which allows air flow to pass through and hinders the passage of cotton material, that is, when the air flow carrying cotton material flows through the cotton inlet channel 213, the exhaust channel 214 and the cotton processing chamber 215 in sequence to form a bend, most of the air flow flows out of the exhaust mesh plate 22 from the exhaust channel 214, and a small part of the air flow carries the cotton material downward into the cotton processing chamber 215.

[0038] In the above embodiment, the mesh size of the exhaust mesh plate 22 can be specifically designed according to the type of cotton material. For example, for recycled cotton, viscose fiber, polyester and other cotton materials, the mesh size can be appropriately reduced to ensure the exhaust effect and prevent the mesh from being blocked by cotton fibers.

[0039] like Figure 2 and Figure 3 As shown, an exhaust pipe 23 may also be provided in the cotton cleaner 2; the exhaust pipe 23 and the exhaust passage 214 are separated by the exhaust mesh plate 22 and the air paths are connected. For example, one end of the exhaust pipe 23 and the exhaust passage 214 are respectively arranged on both sides of the exhaust mesh plate 22, and the other end of the exhaust pipe 23 faces the outside of the cotton cleaner 2. In this embodiment, the exhaust mesh plate 22 as a plate body can separate the exhaust pipe 23 and the exhaust passage 214, and the mesh of the exhaust mesh plate 22 can connect the exhaust pipe 23 and the exhaust passage 214, so that the exhaust pipe 23 and the exhaust passage 214 are connected in air paths. When the airflow carries cotton materials and flows through the cotton inlet passage 213, the exhaust passage 214 and the cotton processing chamber 215 in sequence, most of the airflow flows from the exhaust mesh plate 22 into the exhaust pipe 23, and then is discharged from the cotton cleaner 2 from the exhaust pipe 23; at the same time, a very small part of the airflow carries cotton materials and flows downward into the cotton processing chamber 215.

[0040] In the above embodiment, the cotton inlet channel 213 may include an inlet section 2131 and an extension section 2132 connected to each other; wherein the inlet section 2131 is lower than the exhaust channel 214, and the extension section 2132 extends upward and connects to the exhaust channel 214. In combination with the above, it can be seen that the cotton processing chamber 215 extends downward starting from the exhaust channel 214. It can be seen that the cotton inlet channel 213, the exhaust channel 214 and the cotton processing chamber 215 form a curve that can guide the cotton material to flow upward first, then turn along the exhaust channel 214, and finally flow downward. Usually, the angle between the inlet position and the outlet position of the aforementioned curve is greater than or equal to 90° and less than 180°.

[0041] In the above embodiment, the cotton inlet channel 213 and the exhaust mesh plate 22 are respectively located on two opposite sides of the exhaust channel 214. Figure 3 As shown, the cotton inlet channel 213 is located on the left side of the exhaust channel 214, and the exhaust mesh plate 22 is located on the right side of the exhaust channel 214. When the airflow carries the cotton material and flows through the cotton inlet channel 213, the exhaust channel 214 and the cotton processing chamber 215 in sequence, the relative position relationship between the cotton inlet channel 213 and the exhaust mesh plate 22 can guide more airflow to be discharged from the exhaust mesh plate 22, thereby preventing more airflow from entering the cotton processing chamber 215 and generating a higher flow rate in the cotton processing chamber 215, thereby preventing the airflow from interfering with the processing effect of the cotton material in the cotton processing chamber 215.

[0042] In some embodiments, the cotton processing chamber 215 may include a connected cotton storage channel 2151 (also known as a cotton box) and a loosening and debris removal channel 2152; the cotton storage channel 2151 extends vertically and can temporarily store cotton materials; the loosening and debris removal channel 2152 is located below the cotton storage channel 2151, and is provided with a loosening and debris removal component 24 for breaking up the cotton materials.

[0043] For reference Figure 3 In the above embodiment, the exhaust channel 214, the cotton storage channel 2151 and the loosening and debris removal channel 2152 are sequentially distributed from top to bottom in the cotton cleaning machine 2 and are interconnected. After the airflow carries the cotton into the exhaust channel 214, most of the airflow is discharged from the exhaust mesh plate 22, and a very small part of the airflow flows into the cotton storage channel 2151 with the cotton. After the cotton continuously enters the cotton storage channel 2151, it can be temporarily stored in the cotton storage channel 2151; wherein, the cotton at the bottom of the cotton storage channel 2151 enters the loosening and debris removal channel 2152 in an orderly manner at a relatively slow speed. The loosening and debris removal component 24 is provided in the loosening and debris removal channel 2152, and the loosening and debris removal component 24 can break up the cotton, so that the clumped cotton is dispersed into uniform and fine strips and flocculent cotton, and can often remove impurities such as cotton seeds, seed cotton, leaf debris, short lint, mud and sand in the cotton.

[0044] Still available for reference Figure 3, the loosening and impurity removal component 24 may include a cotton feeding roller 241, a beater 242 and a dust bar group 243; the cotton feeding roller 241, the beater 242 and the dust bar group 243 are arranged in the loosening and impurity removal channel 2152 from top to bottom in sequence; the cotton feeding roller 241 is arranged above the beater 242, and is used to transport cotton materials toward the beater 242, so that the cotton materials can be transported to a specific part of the beater 242 along a specific path; the beater 242 is fixedly mounted in the loosening and impurity removal component 24, and when the beater 242 rotates, it can preliminarily break up the cotton materials and separate the cotton materials from impurities, and at the same time guide the cotton materials and impurities to move downward along different routes; the dust bar group 243 is arranged below the beater 242, and the dust bar group 243 includes a plurality of rotatable dust bars 2431, and these dust bar groups 243 can further break up the cotton materials and further separate the cotton materials from impurities. It can be seen that this embodiment uses the beater 242 and the dust bar group 243 to break up the cotton materials in sequence.

[0045] For reference Figures 3 to 5 In the above embodiment, the loosening and debris removal channel 2152 includes a rotating chamber 21521 that can accommodate a beater 242, and the loosening and debris removal component 24 also includes a rigid supporting plate 244; the dust stick group 243 also includes a mounting frame 2432, and a plurality of dust sticks 2431 are rotatably mounted on the mounting frame 2432 around their respective rotating axes; the rigid supporting plate 244 and the mounting frame 2432 are both arc-shaped plates, and the rigid supporting plate 244 and the mounting frame jointly surround the circumferential lower half of the rotating chamber 21521, and the lower end of the rigid supporting plate 244 is connected to the upper end of the mounting frame 2432, for example, the mounting frame 2432 is located directly below the circumference of the rotating chamber 21521, and the rigid supporting plate 244 is located obliquely below the circumference of the rotating chamber 21521. When the loosening and impurity removal component 24 processes the cotton material, the cotton feeding roller 241 transports the cotton material toward the beater 242, so that the cotton material is transported to a specific position of the beater 242 along a specific path; the beater 242 rotates on a fixed axis to preliminarily break up the cotton material and separate the cotton material from impurities; the cotton material processed by the beater 242 falls down, and part of the cotton material directly falls on the dust bar group 243, and is broken up and separated again by the dust bar group 243, and part of the cotton material falls onto the rigid supporting plate 244, and then gradually enters the dust bar group 243 along the rigid supporting plate 244.

[0046] In addition, on the basis of the above-mentioned embodiment, a supporting rod 246 and a locking assembly are further provided in the loosening and dropping assembly 24; a plurality of supporting rods 246 are fixedly installed in the loosening and dropping assembly 24, and each supporting rod 246 is provided with a locking assembly; both ends of the mounting frame 2432 and both ends of the rigid supporting plate 244 are provided with hooks 245 bent downward. In this embodiment, both the mounting frame 2432 and the rigid supporting plate 244 can be hung between the two supporting rods 246 through the hooks 245, and the locking assemblies on each supporting rod 246 can lock and fix the hooks 245. It can be seen that the mounting frame 2432 and the rigid supporting plate 244 are installed in the same manner, and modular interchangeability can be achieved.

[0047] Taking the mounting frame 2432 as an example, when the mounting position of the mounting frame 2432 needs to be adjusted, the locking assembly can be unlocked first, and then the mounting frame 2432 is moved along the supporting rod 246 to adjust the mounting frame 2432 to a new target position, and finally the mounting frame 2432 and the supporting rod 246 are locked by the locking assembly; when the mounting frame 2432 needs to be disassembled, the locking assembly can be unlocked first, and then the mounting frame 2432 and its hook 245 are moved upward to separate the hook 245 from the supporting rod 246, and finally the mounting frame 2432 is moved out of the cotton cleaning machine 2. This embodiment provides a simple, easy, fast and accurate installation method for the dust stick group 243, which is conducive to the operator to maintain the dust stick group 243 in time and ensure the dust stick group 243 has the effect of breaking up, conveying and separating the cotton material.

[0048] Generally, when processing cotton fibers, the loosening and debris removal component 24 may include two groups of dust bar groups 243, which focuses on removing large impurities of machine-picked cotton; when processing viscose fibers and polyester, the loosening and debris removal component 24 may include one group of dust bar groups 243 and one group of rigid support plates 244, which focuses on opening viscose fibers and polyester, and can also remove a small amount of stiff blocks and dust. The cotton cleaning device can flexibly combine the dust bar group 243 and the rigid support plate 244 according to actual needs, meet the processing requirements of various fibers, and improve the scope of application.

[0049] In some of the embodiments provided above, two photoelectric sensors 4 are provided in the cotton storage channel 2151; the two photoelectric sensors 4 are spaced apart in the up-down direction in the cotton storage channel 2151, that is, one of the photoelectric sensors 4 is located at the upper position in the cotton storage channel 2151, and the other photoelectric sensor 4 is located at the lower position in the cotton storage channel 2151; the cotton mixer 1 and the two photoelectric sensors 4 are coupled to the same host computer, and the host computer can adjust the feeding speed of the cotton mixer 1 in three stages according to the detection signals of the two photoelectric sensors 4. Compared with the current single photoelectric adjustment, the three-stage speed adjustment is conducive to maintaining the pressure of the cotton storage channel 2151 and avoiding affecting the operation quality of the cotton cleaning machine 2.

[0050] With respect to the three-stage speed adjustment of the host computer, an implementation method is provided below.

[0051] Two photoelectric sensors 4 are spaced apart in the cotton storage channel 2151 along the up-down direction. For example, one of the photoelectric sensors 4 is arranged at the upper third of the cotton storage channel 2151, and the photoelectric sensor 4 can be regarded as the first photoelectric sensor. The other photoelectric sensor 4 is arranged at the lower third of the cotton storage channel 2151, and the photoelectric sensor 4 can be regarded as the second photoelectric sensor. When the first photoelectric sensor detects a blocking signal, the upper computer controls the cotton mixer 1 to supply cotton material to the cotton cleaner 2 at a first preset speed; when the first photoelectric sensor does not detect a blocking signal and the second photoelectric sensor detects a blocking signal, the upper computer controls the cotton mixer 1 to supply cotton material to the cotton cleaner 2 at a second preset speed; when the second photoelectric sensor does not detect a blocking signal, the upper computer controls the cotton mixer 1 to supply cotton material to the cotton cleaner 2 at a third preset speed; wherein the third preset speed is greater than the second preset speed, and the second preset speed is greater than the first preset speed.

[0052] In the above example, if the first photoelectric sensor detects an occlusion signal, this means that the cotton material in the cotton storage channel 2151 has filled up the lower two-thirds of the space in the cotton storage channel 2151. At this time, the upper computer slows down the cotton supply speed of the cotton mixer 1, and makes the cotton mixer 1 supply cotton material to the cotton cleaner 2 at a low speed, or stops supplying cotton material to the cotton cleaner 2, so as to avoid the cotton material from continuing to accumulate in large quantities in the cotton storage channel 2151 of the cotton cleaner 2; if the first photoelectric sensor does not detect an occlusion signal and the second photoelectric sensor detects an occlusion signal, this means that the cotton material in the cotton storage channel 2151 has filled up the lower one-third of the space in the cotton storage channel 2151, but has not yet reached the lower two-thirds of the space in the cotton storage channel 2151. At this time, the upper computer makes the cotton mixer 1 supply cotton material to the cotton cleaner 2 at a medium speed to maintain the amount of cotton material accumulated in the cotton storage channel 2151; if the second photoelectric sensor does not detect an occlusion signal, this means that the cotton material in the cotton storage channel 2151 has not yet filled up the lower one-third of the space in the cotton storage channel 2151. At this time, The upper computer instructs the cotton mixer 1 to supply cotton material to the cotton cleaner 2 at a high speed, and quickly increases the amount of cotton material accumulated in the cotton storage channel 2151. It can be seen that the first photoelectric sensor and the second photoelectric sensor in the cotton storage channel 2151 can be combined with the upper computer to jointly control the cotton material supply speed of the cotton mixer 1 to the cotton cleaner 2, realize three-stage speed cotton feeding control, improve the uniformity of the cotton layer in the cotton storage channel 2151, and help maintain the output stability of the cotton cleaner 2, and also help to ensure the processing quality of the cotton material by the cotton cleaner 2.

[0053] In some of the embodiments provided above, the cotton cleaner 2 can be set as a cotton cleaner 2 with a condenser, and at the same time, the conveying fan 3 provided at the inlet and outlet of the cotton cleaner 2 is eliminated. The aforementioned cotton cleaner 2 has a compact structure, and the condenser has the function of blocking the airflow, so that the airflow will not enter the cotton box of the cotton cleaner 2, and thus the cotton layer in the cotton box is uniform. In addition, the condenser can adjust the air volume and wind speed according to the output size to meet the requirements of the cotton outlet air volume and wind pressure of the downstream equipment.

[0054] The cotton cleaning device provided by the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
