Description

Technical Field

[0001] The invention belongs to the field of cotton carding machines, in particular to an automatic cotton carding machine. Background Art

[0002] The carding machine is used to process cotton fiber and chemical fiber. It belongs to textile machinery. According to the spinning process, carding is an important process. The working principle of the carding machine is to open, comb and remove impurities from the cotton rolls sent from the previous process or the oily cotton layer supplied by the cotton box, so that all the curled cotton loops become basically straight single fibers. In the process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed, and then cotton strips of a certain specification are integrated and stored in cotton tubes for use in the drawing process.

[0003] A patent application with publication number CN109281000A discloses a cotton feeding and combing machine, including a frame, a raw material conveying component, a cotton feeding and combing component, and a finished product conveying component. The raw material conveying component, the cotton feeding and combing component, and the finished product conveying component are installed on the frame, and is characterized in that the raw material conveying component includes a first feed roller and a second feed roller provided with gears. The beneficial effect is that the cotton combing mechanism adopts an open structure, which is convenient and quick to clean.

[0004] The traditional carding machine needs to continuously add cotton material into the carding machine, and the carding machine then loosens, combs and removes impurities on the cotton material. The existing carding machine technology is relatively mature, but in the feeding stage, the cotton material is soft but entangled with each other and cannot be directly fed into the carding machine. Traditionally, the cotton material is spread on a conveyor belt, and the conveyor belt is used to gradually feed the cotton material into the carding machine, and the cotton material is squeezed when entering the carding machine. Since the cotton material is relatively fluffy and light in weight, the use of a long-distance conveyor belt is not only prone to problems during the transmission process, but also occupies a large space. Therefore, a short-distance conveyor belt is generally used, and the cotton yarn is slowly placed on the conveyor belt by manual means. The overall operation is relatively cumbersome and difficult to achieve full automation.

[0005] Therefore, the present invention provides an automatic carding machine. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the automatic cotton carding machine described in the present invention comprises a cover-type cotton carding machine body and a cotton material box, the cotton material box is located on one side of the feeding end of the cover-type cotton carding machine body, a movable moving tube is arranged above the cotton material box, the moving tube is made of a flexible material, a grabbing component is arranged at the end of the moving tube, the grabbing component is used to grab the cotton material inside the cotton material box, and a negative pressure pump is connected between the input end of the cover-type cotton carding machine body and the moving tube;

[0008] By setting up the cotton material box, it is only necessary to pile up the cotton material in the cotton material box, put the moving tube into the cotton material box, generate directional suction through the negative pressure pump, suck the cotton material in the cotton material box to the port of the moving tube, and grab the cotton material around the moving tube into the moving tube through the grabbing component, and then it can be transmitted to the cover-type carding machine body by suction for opening, combing and impurity removal. The grabbing of the grabbing component will only grab an appropriate amount of cotton material each time. When encountering a large volume of cotton material, it will also grab a part of the cotton material from the large ball of cotton material and send it into the moving tube. At the same time, the suction of the moving tube will also absorb the scattered cotton material. Through this setting, the moving tube can always input an appropriate amount of cotton material into the cover-type carding machine body, and it is only necessary to pour the cotton material directly into the large volume of cotton material box and wait for the absorption and grabbing of the moving tube. At the same time, the end of the moving tube can move. When the cotton material at the front end of the cotton material box is grabbed, the moving tube will move to the rear end to grab the remaining cotton material.

[0009] Preferably, the grabbing assembly includes four grabbing arms, the grabbing arms are bent, the surface of the grabbing arms is rounded, and a power assembly is provided on the outside of the moving tube. The power assembly is used to drive the grabbing arms to bend and unfold, and the four grabbing arms are driven to open and close by the power assembly. The ends of the grabbing arms rub against the cotton material, and during the closing process, part of the cotton material is pulled into the moving tube, thereby achieving the effect of continuously grabbing cotton material of appropriate size. Moreover, since the grabbing arms are constantly opening and closing, even if a large piece of cotton material is blocked on the outside of the moving tube, it will be pushed outward by the grabbing arms, so that the moving tube can work normally.

[0010] Preferably, the front end of the movable tube is fixedly connected with an absorption sleeve, and the absorption sleeve is made of solid material. Four connecting holes are opened on the outer side of the absorption sleeve near the end, and the two ends of the grabbing arm are through-set, and one end of the grabbing arm is fixedly connected to the connecting hole. The friction grabbing method of the grabbing arm is generally efficient, and the four grabbing arms are connected to the absorption sleeve. The suction generated by the absorption sleeve will directly act on the end of the grabbing arm. During the opening and closing process of the grabbing arm, the suction generated at the end will absorb part of the cotton material in the large cotton material. Since the opening at the end of the grabbing arm is small, the cotton material will be pulled off the large cotton material during the return process of the grabbing arm. Then, as the grabbing arm closes, the end of the grabbing arm faces the absorption sleeve. At this time, the suction direction will be distorted, so that the sucked cotton material falls from the grabbing arm into the absorption sleeve. Through this arrangement, the grabbing arm can use the suction of the movable tube to pull cotton material of appropriate size out of the large cotton material. Since it is pulled by suction, the cotton material will not be damaged, and the effect of grabbing the cotton material is also improved.

[0011] Preferably, the cross-sections of the absorption sleeve and the movable tube are both elliptical, and the four grabbing arms are located at the flat ends of the elliptical movable tube. The outer surfaces of the grabbing arms are fixed with a plurality of protrusions for increasing friction, and the interiors of the grabbing arms are fixed with elastic metal sheets. A pullback assembly is provided on the outer side of the movable tube. When the absorption sleeve sinks to the bottom, the wider side of the elliptical absorption sleeve will fit with the bottom of the cotton material box, and then in the process of continuous opening and closing of the grabbing arms, the outer surfaces of the grabbing arms will continuously rub the bottom of the cotton material box, forcing the absorption sleeve to move toward the rear end of the cotton material box, and when the movable tube moves to the rearmost end of the cotton material box, the pullback assembly will pull the movable tube back to its original position, and then the movable tube will continue to move forward, so that the cotton material accumulated in the cotton material box can be completely absorbed. In this way, the preparation work only needs to pile up the cotton material in the cotton material box.

[0012] Preferably, a ring-shaped magnet is fixedly connected to the middle part of the absorption sleeve, the outer walls of the cotton material box are made of plastic, the bottom plate of the cotton material box is made of magnetizable metal, and a swingable detection head is installed on the inner side of the movable tube. The detection head is a column with a smooth surface. Through the mutual adsorption of the magnet and the cotton material box, the absorption sleeve exerts a greater pressure on the bottom of the cotton material box. In this way, during the opening and closing of the grabbing arm, the reaction force generated by the cotton material box on the grabbing arm is sufficient to push the absorption sleeve forward. The detection head is arranged so that when only airflow passes through, the surface of the detection head is smooth and will not swing. The detection head will only swing when the airflow carries cotton material to hit the detection head, so that timely detection can be carried out.

[0013] Preferably, the power assembly includes a cable, both ends of which are fixedly connected to the outer side of the grabbing arm at both ends, four pulling boxes are fixedly connected to the outer side of the absorption sleeve, a servo motor is installed on the inner side of the pulling box, the middle part of the cable passes through the connection between the grabbing arm and the absorption sleeve, the middle part of the cable is wrapped around the outer side of the output end of the servo motor, and is driven by the servo motor. Since the cable is wrapped around the outer side of the output end of the servo motor, the cable can be controlled to move when the servo motor rotates. At the same time, since the middle part of the cable is fixedly connected to the grabbing arm, the opening and closing of the grabbing arm can be controlled by controlling the forward and reverse rotation of the servo motor.

[0014] Preferably, an absorption head is fixedly connected to the end of the grabbing arm, and a plurality of adsorption tubes are fixedly connected to the end of the absorption head. The adsorption tubes are arranged in a truncated cone shape, and a sealing block is fixedly connected to the outer side of the middle part of the absorption sleeve of the pulling cable. The sealing block is made of elastic material. Through the arrangement of the absorption head, the suction force generated by the absorption sleeve is dispersed to the plurality of absorption heads. Since the diameter of the end of the absorption head is relatively small, it is easier to grasp the cotton material when absorbing the cotton material, and the grasped cotton material can be spit out after the suction force is lost. During the closing process of the grabbing arm, the sealing block will block the connection between the moving tube and the grabbing arm under the pull of the pulling cable, so that the suction force cannot be transmitted to the grabbing arm, so that the cotton material grasped by the adsorption tube will be loosened, and then transported to the cover-type cotton combing machine body under the negative pressure of the moving tube.

[0015] Preferably, a separation plate is provided between the absorption head and the grabbing arm, and the area of ​​the separation plate is the same as that of the absorption head. Two symmetrically arranged spring telescopic rods are fixedly connected between the separation plate and the absorption head. When the suction force is transmitted to the grabbing arm, the spring telescopic rods are stretched under the pulling of the suction force, and the separation plate is away from the absorption head. The area of ​​the separation plate is smaller than the front end of the grabbing arm, so that the suction force can be normally delivered to the adsorption tube. When the grabbing arm is closed, the suction force inside the grabbing arm disappears. At this time, the spring telescopic rod quickly returns to its position, which will generate an airflow thrust to the adsorption tube, thereby pushing out the cotton material fixed at the end of the adsorption tube, assisting the cotton material to detach from the end of the adsorption tube and then enter the absorption sleeve.

[0016] Preferably, the pullback assembly includes an adjusting tube, the adjusting tube is connected between the negative pressure pump and the moving tube, the end of the moving tube is slidably connected to the inside of the adjusting tube, the top and bottom surfaces of the adjusting tube are fixedly connected to a power box, a reduction motor is fixedly connected in the power box, a steel cable is fixedly connected between the output end of the reduction motor and the moving tube, the top of the adjusting tube is connected to a screw nut mechanism for driving the horizontal movement of the adjusting tube, the output end of the negative pressure pump is slidably engaged with the cover-type cotton combing machine body, when the absorption sleeve moves toward the rear end with the moving tube, the moving tube in the adjustment tube will slide outward, when it slides out to the limit, the steel cable will be completely straightened, a rotation counting module is installed inside the reduction motor, which can record the number of rotations of the reduction motor, when the steel cable rotates to be straightened, the reduction motor drives the winding steel cable to pull the moving tube back into the adjustment tube, so that the position of the absorption sleeve can be reset, so that the absorption sleeve can continuously absorb the cotton material in the cotton material box.

[0017] Preferably, the negative pressure pump includes an outer shell, a circulation groove is provided in the outer shell, and two power wheels are rotatably clamped in the circulation groove. The two power wheels have three smooth protrusions, and the two power wheels are meshed with each other. The outer side of one of the power wheels is connected to a driving motor for driving the power wheel to rotate. The power wheel is driven to rotate by the driving motor, and the two power wheels rotate simultaneously in a meshing state, continuously transporting the air at one end to the other end, thereby generating suction. Since the power wheel has a simple structure and stable operation, the airflow and the cotton material carried in the airflow can be effectively input into the cover-type cotton combing machine body.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The automatic cotton combing machine described in the present invention, through the setting of the cotton material box, only needs to pile up the cotton material in the cotton material box, put the mobile tube into the cotton material box, generate directional suction through the negative pressure pump, suck the cotton material in the cotton material box to the port of the mobile tube, and grab the cotton material around the mobile tube into the mobile tube through the grabbing component, and then it can be transmitted to the cover plate type cotton combing machine body by suction to perform opening, combing and impurity removal. The grabbing component will only grab an appropriate amount of cotton material each time. When encountering a large volume of cotton When the cotton material is being fed into the moving tube, a part of the cotton material will be grabbed from the large ball of cotton material and fed into the moving tube. At the same time, the suction of the moving tube will absorb the scattered cotton material. Through this arrangement, the moving tube can always input an appropriate amount of cotton material into the cover-type cotton carding machine body, and it is only necessary to pour the cotton material directly into the large-volume cotton material box and wait for the moving tube to absorb and grab it. At the same time, the end of the moving tube can move. When the cotton material at the front end of the cotton material box is grabbed, the moving tube will move to the rear end to grab the remaining cotton material.

[0020] 2. The automatic cotton carding machine described in the present invention drives the opening and closing of four grabbing arms through a power component. The ends of the grabbing arms rub against the cotton material. During the closing process, part of the cotton material is pulled into the moving tube, thereby achieving the effect of continuously grabbing cotton material of appropriate size. Moreover, since the grabbing arms are constantly opening and closing, even if a large piece of cotton material is blocked on the outside of the moving tube, it will be pushed outward by the grabbing arms, allowing the moving tube to work normally.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 3As shown, an automatic cotton carding machine according to an embodiment of the present invention comprises a cover-type cotton carding machine body 1 and a cotton material box 3, wherein the cotton material box 3 is located at one side of the feeding end of the cover-type cotton carding machine body 1, and a movable moving tube 5 is arranged above the cotton material box 3, wherein the moving tube 5 is made of a flexible material, and a grabbing component is arranged at the end of the moving tube 5, wherein the grabbing component is used to grab the cotton material inside the cotton material box 3, and a negative pressure pump 19 is connected between the input end of the cover-type cotton carding machine body 1 and the moving tube 5;

[0032] The traditional carding machine needs to continuously add cotton materials into the carding machine, and the carding machine then performs tasks such as loosening, combing and removing impurities on the cotton materials. The existing carding machine technology is relatively mature, but in the feeding stage, since the cotton materials are soft but entangled with each other, they cannot be directly fed into the carding machine. Traditionally, the cotton materials are flattened on the conveyor belt and gradually fed into the carding machine with the conveyor belt. The cotton materials are squeezed when entering the carding machine. Since the cotton materials are relatively fluffy and light in weight, the use of long-distance conveyor belts is not only prone to problems during the transmission process, but also occupies a large space. Therefore, short-distance conveyor belts are generally used, and the cotton yarn is slowly placed on the conveyor belt by manual methods. The overall operation is relatively cumbersome and difficult to achieve full automation;

[0033] Through the setting of the cotton material box 3, it is only necessary to pile up the cotton material in the cotton material box 3, put the mobile tube 5 into the cotton material box 3, and generate directional suction through the negative pressure pump 19 to suck the cotton material in the cotton material box 3 to the port of the mobile tube 5, and grab the cotton material around the mobile tube 5 into the mobile tube 5 through the grabbing component, and then it can be transmitted to the cover type carding machine body 1 by suction to perform work such as loosening, combing and impurity removal. The grabbing component will only grab an appropriate amount of cotton material each time. When encountering a large volume of cotton material, it will also grab the large amount of cotton material from the large volume. A portion of the cotton material is grabbed from the cotton ball and fed into the moving tube 5, and the suction force of the moving tube 5 will also absorb the scattered cotton material. Through this arrangement, the moving tube 5 can always input an appropriate amount of cotton material into the cover-type cotton carding machine body 1, and it is only necessary to pour the cotton material directly into the large-volume cotton material box 3 and wait for the mobile tube 5 to absorb and grab it. At the same time, the end of the moving tube 5 can move. When the cotton material at the front end of the cotton material box 3 is grabbed, the moving tube 5 will move to the rear end to grab the remaining cotton material.

[0034] like Figures 1 to 5 As shown, the grabbing assembly includes four grabbing arms 8, the grabbing arms 8 are arranged in a bent shape, the surface of the grabbing arms 8 is arranged in a smooth shape, and a power assembly is arranged on the outer side of the moving tube 5, and the power assembly is used to drive the grabbing arms 8 to bend and unfold;

[0035] During operation, the four grabbing arms 8 are driven to open and close by the power assembly, and the ends of the grabbing arms 8 rub against the cotton material. During the closing process, part of the cotton material is pulled into the moving tube 5, thereby achieving the effect of continuously grabbing cotton material of appropriate size. Moreover, since the grabbing arms 8 are constantly opening and closing, even if large pieces of cotton material are blocked on the outside of the moving tube 5, they will be pushed outward by the grabbing arms 8, so that the moving tube 5 can work normally.

[0036] like Figures 1 to 5 As shown, the front end of the moving tube 5 is fixedly connected with an absorption sleeve 6, the absorption sleeve 6 is made of solid material, and four communication holes 9 are opened on the outer side of the absorption sleeve 6 near the end, and the two ends of the grabbing arm 8 are through-set, and one end of the grabbing arm 8 is fixedly connected to the communication hole 9;

[0037] When working, the friction grabbing method of the grabbing arms 8 is generally efficient. The four grabbing arms 8 are connected to the absorption sleeve 6. The suction generated by the absorption sleeve 6 will directly act on the end of the grabbing arms 8. During the opening and closing process of the grabbing arms 8, the suction generated at the end will suck part of the cotton material in the large cotton material. Since the opening at the end of the grabbing arms 8 is small, the cotton material will be pulled off the large cotton material during the return process of the grabbing arms 8. Then, as the grabbing arms 8 close, the end of the grabbing arms 8 faces the absorption sleeve 6. At this time, the suction direction will be distorted, causing the sucked cotton material to fall from the grabbing arms 8 into the absorption sleeve 6. Through this arrangement, the grabbing arms 8 can use the suction of the moving tube 5 to pull cotton material of appropriate size out of the large cotton material. Since it is pulled by suction, the cotton material will not be damaged. At the same time, the effect of grabbing the cotton material is also improved. The absorption sleeve 6 can be made of common ABS resin material.

[0038] like Figures 1 to 6 As shown, the cross-sections of the absorption sleeve 6 and the moving tube 5 are both elliptical, and the four grabbing arms 8 are located at the two flat ends of the elliptical moving tube 5. The outer surface of the grabbing arm 8 is fixed with a plurality of protrusions for increasing friction, and the inside of the grabbing arm 8 is fixed with an elastic metal sheet, and the outer side of the moving tube 5 is provided with a pull-back component;

[0039] During operation, after the absorption sleeve 6 sinks to the bottom, the wider side of the elliptical absorption sleeve 6 will fit with the bottom of the cotton material box 3, and then in the continuous opening and closing process of the grabbing arm 8, the outer surface of the grabbing arm 8 will continuously rub the bottom of the cotton material box 3, forcing the absorption sleeve 6 to move toward the rear end of the cotton material box 3. When the moving tube 5 moves to the rear end of the cotton material box 3, the pull-back assembly will pull the moving tube 5 back to its original position, and then the moving tube 5 will continue to move forward, so that the cotton material accumulated in the cotton material box 3 can be absorbed completely. In this way, the preparation work only needs to pile up the cotton material in the cotton material box 3.

[0040] like Figures 1 to 6As shown, a ring-shaped magnet is fixedly connected to the middle of the absorption sleeve 6, the outer wall of the cotton material box 3 is made of plastic material, the bottom plate of the cotton material box 3 is made of magnetizable metal material, and a swingable detection head 7 is installed on the inner side of the moving tube 5, and the detection head 7 is a column with a smooth surface;

[0041] During operation, the absorption sleeve 6 exerts a greater pressure on the bottom of the cotton material box 3 through the mutual adsorption of the magnet and the cotton material box 3. In this way, during the opening and closing of the grabbing arm 8, the reaction force generated by the cotton material box 3 on the grabbing arm 8 is sufficient to push the absorption sleeve 6 forward. The detection head 7 is arranged so that when only airflow passes through, the surface of the detection head 7 is smooth and will not swing. Only when the airflow carries cotton material and hits the detection head 7, the detection head 7 will swing, so that timely detection can be carried out.

[0042] like Figures 1 to 6 As shown, the power assembly includes a cable 11, the two ends of the cable 11 are respectively fixed to the outer side of the grabbing arm 8, four pulling boxes 22 are fixed to the outer side of the absorption sleeve 6, and a servo motor is installed on the inner side of the pulling box 22. The middle part of the cable 11 passes through the connection between the grabbing arm 8 and the absorption sleeve 6, and the middle part of the cable 11 is wrapped around the outer side of the output end of the servo motor.

[0043] During operation, it is driven by a servo motor. Since the cable 11 is wrapped around the outside of the output end of the servo motor, the cable 11 can be controlled to move when the servo motor rotates. At the same time, since the middle part of the cable 11 is fixedly connected to the grabbing arm 8, the opening and closing of the grabbing arm 8 can be controlled by controlling the forward and reverse rotation of the servo motor.

[0044] like Figures 1 to 6 As shown, the end of the grabbing arm 8 is fixedly connected to an absorption head 12, and the end of the absorption head 12 is fixedly connected to a plurality of absorption tubes 14, and the absorption tubes 14 are arranged in a truncated cone shape. The cable 11 is located at the outside of the middle of the absorption sleeve 6 and is fixedly connected to a sealing block 10, and the sealing block 10 is made of elastic material;

[0045] During operation, the suction force generated by the absorption sleeve 6 is dispersed to multiple absorption heads 12 through the setting of the absorption head 12. Since the diameter of the end of the absorption head 12 is small, it is easier to grasp the cotton material when absorbing it. After the suction force is lost, the grasped cotton material is spit out. During the closing process of the grabbing arm 8, under the pull of the cable 11, the sealing block 10 will block the connection between the moving tube 5 and the grabbing arm 8, so that the suction force cannot be transmitted to the grabbing arm 8. In this way, the cotton material grasped by the absorption tube 14 will be loosened, and then transported to the cover-type cotton carding machine body 1 under the negative pressure of the moving tube 5.

[0046] like Figures 1 to 6As shown, a separation disc 15 is provided between the absorption head 12 and the grabbing arm 8, the area of ​​the separation disc 15 is the same as that of the absorption head 12, and two symmetrically arranged spring telescopic rods 16 are fixedly connected between the separation disc 15 and the absorption head 12;

[0047] During operation, after the suction force is transmitted to the grabbing arm 8, the spring telescopic rod 16 is extended under the pull of the suction force, and the separation plate 15 is away from the absorption head 12. The area of ​​the separation plate 15 is smaller than the front end of the grabbing arm 8, so that the suction force can be normally transmitted to the adsorption tube 14. When the grabbing arm 8 is closed, the suction force inside the grabbing arm 8 disappears. At this time, the spring telescopic rod 16 quickly returns to its position, which will generate an airflow thrust for the adsorption tube 14, thereby pushing out the cotton material fixed at the end of the adsorption tube 14, and assisting the cotton material to detach from the end of the adsorption tube 14 and then enter the absorption sleeve 6.

[0048] like Figures 1 to 6 As shown, the pullback assembly includes an adjustment tube 4, which is connected between a negative pressure pump 19 and a moving tube 5, and the end of the moving tube 5 is slidably connected to the inside of the adjustment tube 4. The top and bottom surfaces of the adjustment tube 4 are fixedly connected with a power box 18, and a reduction motor is fixedly connected in the power box 18. A steel cable 17 is fixedly connected between the output end of the reduction motor and the moving tube 5. The top of the adjustment tube 4 is connected with a screw nut mechanism 2 for driving the adjustment tube 4 to move horizontally, and the output end of the negative pressure pump 19 is slidably engaged with the cover-type carding machine body 1;

[0049] During operation, when the absorption sleeve 6 moves toward the rear end with the movable tube 5, the movable tube 5 in the adjustment tube 4 will slide outward. When it slides out to the limit, the steel cable 17 will be completely straightened. A rotation counting module is installed inside the reduction motor to record the number of rotations of the reduction motor. When the steel cable 17 rotates to be straightened, the reduction motor drives the winding steel cable 17 to pull the movable tube 5 back into the adjustment tube 4. In this way, the position of the absorption sleeve 6 can be reset, so that the absorption sleeve 6 can continuously absorb the cotton material in the cotton material box 3.

[0050] like Figures 1 to 7 As shown, the negative pressure pump 19 includes a shell, a flow slot 21 is opened in the shell, and two power wheels 20 are rotatably clamped in the flow slot 21. The two power wheels 20 have three smooth protrusions, and the two power wheels 20 are meshed with each other. The outer side of one of the power wheels 20 is connected to a driving motor for driving the power wheel 20 to rotate;

[0051] During operation, the power wheel 20 is driven to rotate by the driving motor, and the two power wheels 20 rotate simultaneously in a meshing state, continuously transporting the air at one end to the other end, thereby generating suction. Since the power wheel 20 has a simple structure and stable operation, the airflow and the cotton material carried in the airflow can be effectively input into the cover-type cotton carding machine body 1.

[0052] During operation, through the setting of the cotton material box 3, it is only necessary to pile up the cotton material in the cotton material box 3, put the mobile tube 5 into the cotton material box 3, and generate directional suction through the negative pressure pump 19 to suck the cotton material in the cotton material box 3 to the port of the mobile tube 5, and grab the cotton material around the mobile tube 5 into the mobile tube 5 through the grabbing component, and then it can be transmitted to the cover type carding machine body 1 by suction to perform work such as loosening, combing and impurity removal. The grabbing component will only grab an appropriate amount of cotton material each time, and when encountering a large volume of cotton material, it will also Grab a portion of cotton material from the large ball of cotton material and feed it into the moving tube 5. At the same time, the suction force of the moving tube 5 will also absorb the scattered cotton material. Through this arrangement, the moving tube 5 can always input an appropriate amount of cotton material into the cover-type carding machine body 1, and the cotton material only needs to be directly poured into the large-volume cotton material box 3 and wait for the absorption and grabbing of the moving tube 5. At the same time, the end of the moving tube 5 can be moved. When the cotton material at the front end of the cotton material box 3 is grabbed, the moving tube 5 will move to the rear end to grab the remaining cotton material.

[0053] The four grabbing arms 8 are driven to open and close by the power assembly, and the ends of the grabbing arms 8 rub against the cotton material. During the closing process, part of the cotton material is pulled into the moving tube 5, thereby achieving the effect of continuously grabbing cotton material of appropriate size. Moreover, since the grabbing arms 8 are continuously opened and closed, even if a large piece of cotton material is blocked on the outside of the moving tube 5, it will be pushed outward by the grabbing arms 8, so that the moving tube 5 can work normally.

[0054] The efficiency of the friction grabbing method of the grabbing arms 8 is generally good. The four grabbing arms 8 are connected to the absorption sleeve 6. The suction generated by the absorption sleeve 6 will directly act on the ends of the grabbing arms 8. During the opening and closing process of the grabbing arms 8, the suction generated at the ends will suck part of the cotton in the large cotton. Since the opening at the ends of the grabbing arms 8 is small, the cotton will be pulled off the large cotton during the return process of the grabbing arms 8. Then, as the grabbing arms 8 are closed, the ends of the grabbing arms 8 face the absorption sleeve 6. At this time, the suction direction will be distorted, so that the sucked cotton falls from the grabbing arms 8 into the absorption sleeve 6. Through this arrangement, the grabbing arms 8 can use the suction of the moving tube 5 to pull cotton of appropriate size out of the large cotton. Since it is pulled by suction, the cotton will not be damaged, and the effect of grabbing the cotton is also improved.

[0055] When the absorption sleeve 6 sinks to the bottom, the wider side of the elliptical absorption sleeve 6 will fit with the bottom of the cotton material box 3. Then, during the continuous opening and closing of the grabbing arm 8, the outer surface of the grabbing arm 8 will continuously rub the bottom of the cotton material box 3, forcing the absorption sleeve 6 to move toward the rear end of the cotton material box 3. When the moving tube 5 moves to the rear end of the cotton material box 3, the pull-back assembly will pull the moving tube 5 back to its original position, and then the moving tube 5 will continue to move forward, so that the cotton accumulated in the cotton material box 3 can be completely absorbed. In this way, the preparation work only needs to accumulate the cotton in the cotton material box 3.

[0056] Through the mutual adsorption of the magnet and the cotton material box 3, the absorption sleeve 6 exerts a greater pressure on the bottom of the cotton material box 3. In this way, during the opening and closing of the grabbing arm 8, the reaction force generated by the cotton material box 3 on the grabbing arm 8 is sufficient to push the absorption sleeve 6 forward. The detection head 7 is set so that when only airflow passes through, the surface of the detection head 7 is smooth and will not swing. Only when the airflow carries cotton materials and hits the detection head 7, the detection head 7 will swing, so that timely detection can be carried out.

[0057] Driven by a servo motor, since the cable 11 is wound around the outer side of the output end of the servo motor, the cable 11 can be controlled to move when the servo motor rotates. At the same time, since the middle part of the cable 11 is fixedly connected to the grabbing arm 8, the opening and closing of the grabbing arm 8 can be controlled by controlling the forward and reverse rotation of the servo motor.

[0058] By setting the absorption head 12, the suction force generated by the absorption sleeve 6 is dispersed to multiple absorption heads 12. Since the diameter of the end of the absorption head 12 is small, it is easier to grasp the cotton material when absorbing the cotton material. After the suction force is lost, the grasped cotton material is spit out. When the grabbing arm 8 is closed, the sealing block 10 will block the connection between the moving tube 5 and the grabbing arm 8 under the pulling of the cable 11, so that the suction force cannot be transmitted to the grabbing arm 8, so that the cotton material grasped by the absorption tube 14 will be loosened, and then transported to the cover-type carding machine body 1 under the negative pressure of the moving tube 5;

[0059] When the suction force is transmitted to the grabbing arm 8, the spring telescopic rod 16 is stretched under the suction force, and the separation disc 15 is away from the absorption head 12. The area of ​​the separation disc 15 is smaller than the front end of the grabbing arm 8, so that the suction force can be normally transmitted to the absorption tube 14. When the grabbing arm 8 is closed, the suction force inside the grabbing arm 8 disappears. At this time, the spring telescopic rod 16 quickly returns to its position, which will generate an airflow thrust to the absorption tube 14, thereby pushing out the cotton material fixed at the end of the absorption tube 14, and assisting the cotton material to detach from the end of the absorption tube 14 and then enter the absorption sleeve 6.

[0060] When the absorbing sleeve 6 moves toward the rear end with the moving tube 5, the moving tube 5 in the adjusting tube 4 will slide outward. When it slides out to the limit, the steel cable 17 will be completely straightened. A rotation counting module is installed inside the reduction motor to record the number of rotations of the reduction motor. When the steel cable 17 rotates to be straightened, the reduction motor drives the winding steel cable 17 to pull the moving tube 5 back into the adjusting tube 4. In this way, the position of the absorbing sleeve 6 can be reset, so that the absorbing sleeve 6 can continuously absorb the cotton material in the cotton material box 3.

[0061] The power wheel 20 is driven to rotate by a driving motor, and the two power wheels 20 rotate simultaneously in a meshing state, continuously transporting the air at one end to the other end, thereby generating suction. Since the power wheel 20 has a simple structure and stable operation, the airflow and the cotton material carried in the airflow can be effectively input into the cover-type cotton combing machine body 1.
