Description

Technical Field

[0001] This application relates to the technical field of fiber dyeing equipment, and particularly to a feeding device and a feeding method for loose fiber cakes. Background Art

[0002] Fibers are divided into two major categories: natural fibers and chemical fibers. Natural fibers exist naturally and are further divided into plant fibers, animal fibers, and mineral fibers. Chemical fibers are made through chemical processing and can be divided into artificial fibers, synthetic fibers, and inorganic fibers. Most fibers are loose fibers, and for loose fibers, it is necessary to form them into cakes.

[0003] During the later processing of fiber cakes, it is necessary to perform fiber opening on the fibers. Fiber opening is the process of separating large fiber clusters and lumps into small pieces and bundles. Fiber opening reduces the scale of the lateral connection of fibers and creates conditions for further loosening to the single-fiber state in the future. In the textile industry, it is necessary to use a fiber opener to open the lumped cotton. After fiber opening, the following effects are achieved: separating fibers: separating fiber bundles into single fibers, facilitating the next step of reeling; improving spinning efficiency: through the fiber opening process, fibers can be better dispersed and moisture-absorbed, which can improve the efficiency of the spinning machine; improving the quality of the finished product: the fiber opening process can make the details of the fibers clearer, and the length and diameter distribution of the fibers more uniform, thus improving the quality of the finished product; reducing costs: through the fiber opening process, the efficiency of the spinning machine can be improved, thereby reducing production costs.

[0004] Currently, when using a fiber opener to open fiber cakes, first dehydrate the loose fiber cakes and then transfer them to the fiber opening area of the dryer. Then manually tear the fiber cakes, put the torn fibers into the fiber opener, and the fiber opener starts fiber opening and drying.

[0034] The following Figures 1-5 further elaborates on the present application in detail with reference to the attached

[0035] The embodiment of the present application discloses a feeding device for a loose fiber cake. Refer to Figure 1 and Figure 2, the feeding device for the loose fiber cake includes a material platform 1 and a mounting frame 2 located on one side of the fiber opening machine 3. The fiber cake 17 to be fiber-opened is placed on the material platform 1. The receiving area of the material platform 1 is larger than the bottom area of the fiber cake 17. A feeding pusher 4 is slidably arranged on the mounting frame 2. The feeding pusher 4 is located above the fiber cake 17 to be fiber-opened. The feeding pusher 4 faces the feeding port of the fiber opening machine 3. The area of the feeding port of the fiber opening machine 3 is larger than the area of the fiber layer. The feeding pusher 4 slides in the direction approaching or departing from the feeding port of the fiber opening machine 3. A first driving member is arranged on the mounting frame 2 for driving the feeding pusher 4 to slide and scraping the fiber layer on the surface of the fiber cake 17 into the fiber opening machine 3. In the embodiment of the present application, the first driving member includes a cylinder 5 arranged on the mounting frame 2. The length direction of the output shaft of the cylinder 5 is parallel to the sliding direction of the feeding pusher 4 and the feeding pusher 4 is fixedly arranged on the output shaft of the cylinder 5;

[0036] Refer to Figure 1 , a placing plate 6 is arranged on the material platform 1. The fiber cake 17 is located on the placing plate 6. The placing plate 6 is slidably arranged on the material platform 1. The placing plate 6 slides in the vertical direction. A second driving member is arranged on the material platform 1 for driving the placing plate 6 to slide to send the fiber cake 17 to the feeding pusher 4. In the embodiment of the present application, the second driving member includes a lifter 7 arranged on the material platform 1. The placing plate 6 is fixedly arranged on the lifter 7.

[0037] When the fiber is put into the fiber opening machine 3, first, the fiber cake 17 is hoisted onto the placing plate 6. Subsequently, the placing plate 6 is driven to move by the lifter 7. The placing plate 6 drives the fiber cake 17 to rise. After the fiber cake 17 rises to a position where the surface layer is within the action range of the feeding pusher 4, the cylinder 5 is started. The cylinder 5 drives the feeding pusher 4 to slide. When the feeding pusher 4 slides to the side of the fiber cake 17, the feeding pusher 4 enters the fiber cake 17. The feeding pusher 4 acts on the fiber layer and tears the fiber layer. When the fiber layer is separated from the fiber cake 17, under the action of the feeding pusher 4, the fiber layer slides on the fiber cake 17 and enters the fiber opening machine 3, completing the feeding operation of the fiber layer. The operation is simple and convenient and the feeding efficiency is relatively high.

[0038] Furthermore, magnetic switches are arranged on both the mounting frame 2 and the fiber opening machine 3. Both magnetic switches are connected to the control system of the cylinder 5; by adjusting the distance between the two magnetic switches, the operating stroke of the conveying shaft of the cylinder 5 is adjusted, thereby facilitating the feeding operation of the fiber cake 17.

[0039] Furthermore, a grating sensor and a controller are arranged on the fiber opening machine 3. The grating sensor is electrically connected to the controller, and the controller is electrically connected to the lifter 7; the height of the fiber cake 17 is detected by the grating sensor and the controller, and the fiber cake 17 is driven to rise by controlling the lifter 7.

[0040] In other embodiments of the present application, the cylinder 5 can be replaced with an oil cylinder, an electric cylinder, a rodless hydraulic cylinder, etc.

[0041] Referring to Figure 2 and Figure 3 , in the embodiment of the present application, the feeding pusher 4 includes a mounting seat 41 slidably arranged on the mounting frame 2 and a toothed rake 42 arranged on the lower surface of the mounting seat 41. The mounting seat 41 slides in a direction close to or away from the fiber opening machine 3. The mounting seat 41 is fixedly arranged on the output shaft of the cylinder 5. The tooth rods 422 on the toothed rake 42 are evenly and spacedly arranged. When the cylinder 5 pushes the mounting seat 41 to slide, the mounting seat 41 drives the toothed rake 42 to slide. After the toothed rake 42 slides to the side wall of the fiber cake 17, the toothed rake 42 enters the fiber cake 17 to scrape the fiber layer, thereby separating the fiber layer on the surface of the fiber layer. Because the toothed rake 42 is evenly and spacedly arranged, it is convenient for the toothed rake 42 to enter the fiber layer, so as to facilitate the separation of the fiber layer and the fiber cake 17.

[0042] Referring to Figure 2 and Figure 3 , when the toothed rake 42 enters the fiber cake 17 and drives the fiber layer to slide, there is a possibility that some fiber bundles are wound around the toothed rake 42, resulting in a low utilization rate of raw materials. To improve the utilization rate of raw materials, the toothed rake 42 includes a mounting rod 421 arranged on the mounting seat 41 and a plurality of tooth rods 422 arranged on the mounting rod 421. The length direction of the mounting rod 421 is perpendicular to the sliding direction of the mounting seat 41 and parallel to the ground. The plurality of tooth rods 422 are evenly and spacedly arranged. The tooth rods 422 are located on the side of the mounting rod 421 away from the mounting seat 41. Further, both the mounting rod 421 and the tooth rods 422 are hollow and communicate with each other. Combining Figure 4 , a plurality of air holes 8 are formed in the tooth rod 422. The air holes 8 are evenly arranged along the circumferential direction of the tooth rod 422 and are staggered along the length direction of the tooth rod 422. A gas supply device is arranged on the mounting seat 41. The gas supply device is used to introduce gas into the tooth rod 422 and eject it from the air holes 8 to separate the fiber wound around the tooth rod 422. The gas supply device includes an air compressor 9 fixedly arranged on the mounting seat 41. The mounting rod 421 is communicated with the output port of the air compressor 9.

[0043] After the toothed rake 42 moves out of the fiber layer on the surface of the fiber cake 17 and during the return process (moving in the direction away from the fiber opening machine 3), the air compressor 9 is started. The air compressor 9 sends the compressed air into the mounting rod 421, and transfers it to the tooth rod 422 through the mounting rod 421, and then ejects it from the air holes 8. During the process of the compressed air being ejected, the fiber bundles wound around the tooth rod 422 are moved out. The moved-out fiber bundles fall on the surface of the fiber cake 17. During the next feeding process, the moved-out fiber bundles are fed into the fiber opening machine 3, thereby improving the utilization rate of raw materials.

[0044] Referring toFigure 3 And Figure 4 , to improve the removal effect of the fiber bundle on the rack 422, the air holes 8 are obliquely formed on the rack 422, and the axis of the air holes 8 is inclined towards the direction close to the end of the rack 422; the air holes 8 are obliquely formed to guide the ejected compressed air, so that the compressed air is ejected obliquely along the direction of the rack 422, and the ejected air acts on the fiber bundle and drives the fiber bundle to slide along the rack 422, thereby improving the removal effect of the fiber bundle.

[0045] Referring to Figure 3 , to facilitate the separation of the fiber layer on the surface of the fiber cake 17, the mounting rod 421 is slidably arranged on the mounting seat 41, the sliding direction of the mounting rod 421 is perpendicular to the sliding direction of the mounting seat 41 on the mounting frame 2, and a third driving member for driving the sliding of the mounting rod 421 is arranged on the mounting seat 41. In the embodiment of the present application, the third driving member includes a reciprocating push rod 10 arranged in the mounting seat 41, and the length direction of the output shaft of the reciprocating push rod 10 is parallel to the length direction of the mounting rod 421. Further, a connecting plate 11 is fixedly arranged on the output shaft of the reciprocating push rod 10, and the mounting rod 421 is fixedly arranged on the connecting plate 11; after the mounting seat 41 drives the mounting rod 421 into the fiber cake 17, the reciprocating push rod 10 is started, and the reciprocating push rod 10 drives the mounting rod 421 to reciprocate in the fiber cake 17, and the sliding of the mounting rod 421 drives the rack 422 to move in the fiber cake 17, thereby tearing the fiber cake 17 to separate the fiber layer, so as to facilitate the fiber layer to enter the fiber opening.

[0046] Referring to Figure 3 And Figure 5 , in the embodiment of the present application, the rack 422 includes a first rod body 4221 fixedly arranged on the mounting rod 421 and a second rod body 4222 hinged to the first rod body 4221. The first rod body 4221 is hollow and communicated with the mounting rod 421. The second rod body 4222 is hollow and the air holes 8 are formed on the second rod body 4222. An air pipe 12 is arranged in the first rod body 4221, and the air pipe 12 is communicated with the second rod body 4222. The air pipe 12 is communicated with the output end of the air compressor 9. The rotation axis of the second rod body 4222 is perpendicular to the sliding direction of the mounting seat 41. A limiting member is arranged on the first rod body 4221, and the limiting member is used to fix the second rod body 4222 to the cutting state when the mounting seat 41 slides towards the fiber opener 3, or the second rod body 4222 resumes the rotation trend to bear on the top surface of the fiber cake 17 when the mounting seat 41 slides away from the fiber opener 3;

[0047] Referring to Figure 3 And Figure 5, The limiting member includes a limiting block 13 provided on the first rod body 4221. The limiting block 13 is triangular. The limiting block 13 is located on the side of the second rod body 4222 away from the fiber opening machine 3. The end of the second rod body 4222 away from the first rod body 4221 is inclined towards the fiber opening machine 3, and the second rod body 4222 is received on the inclined surface of the limiting block 13.

[0048] When the mounting base 41 drives the mounting rod 421 to slide towards the fiber opening machine 3, the second rod body 4222 first abuts against the side wall of the fiber cake 17. Under the action of the reaction force, the second rod body 4222 rotates towards the limiting block 13 and is received on the limiting block 13, and keeps the second rod body 4222 in the above state to enter the fiber cake 17; when the mounting base 41 drives the mounting rod 421 to slide in the direction away from the fiber opening machine 3, since the second rod body 4222 has passed over the fiber cake 17, after the second rod body 4222 contacts the fiber cake 17, the second rod body 4222 rotates in the direction towards the fiber opening machine 3 and then is received on the surface of the fiber cake 17, so as to facilitate the second rod body 4222 to slide to the initial position; further, when the second rod body 4222 returns to the initial position, since it is received on the surface of the fiber cake 17, when compressed air acts on the fiber bundle wound around the second rod body 4222, the fiber bundle separates from the second rod body 4222 and moves onto the fiber cake 17, reducing the possibility of the fiber bundle fluttering.

[0049] Refer to Figure 3 and Figure 5 , Further, when the second rod body 4222 moves in the direction away from the fiber opening machine 3 and passes over the fiber cake 17, in order to facilitate the second rod body 4222 to rotate and be received on the limiting block 13, a hinge shaft 14 is fixedly provided on the first rod body 4221. The second rod body 4222 is rotatably provided on the hinge shaft 14. A torsion spring 15 is sleeved on the hinge shaft 14. One side of the torsion spring 15 is fixedly provided on the hinge shaft 14, and the other side is fixedly provided on the second rod body 4222. The torsion spring 15 drives the second rod body 4222 to have a tendency to rotate in the direction away from the fiber opening machine 3.

[0050] Refer to Figure 3 and Figure 5 , In order to reduce the possibility of the fiber bundle entering the second rod body 4222 through the air hole 8, the air hole 8 is covered with a cover 16. The cover 16 protrudes outward in the direction away from the air hole 8. The air hole 8 is communicated with the internal space of the cover 16. The bottom of the cover 16 is open.

[0051] The implementation principle of a feeding device for loose fiber cakes in an embodiment of the present application is as follows:

[0052] When the fiber is put into the fiber opening machine 3, first, the fiber cake 17 is hoisted and placed on the placing plate 6. Subsequently, the placing plate 6 is driven to move by the elevator 7, and the placing plate 6 drives the fiber cake 17 to rise. After the fiber cake 17 rises to a position where the surface layer is within the action range of the feeding pusher 4, the air cylinder 5 is started. The air cylinder 5 drives the feeding pusher 4 to slide. When the feeding pusher 4 slides to the side of the fiber cake 17, the feeding pusher 4 enters the fiber cake 17. The feeding pusher 4 acts on the fiber layer and tears the fiber layer. When the fiber layer is separated from the fiber cake 17, under the action of the feeding pusher 4, the fiber layer slides on the fiber cake 17 and enters the fiber opening machine 3, completing the feeding operation of the fiber layer. The operation is simple and convenient, and the feeding efficiency is relatively high.

[0053] When the feeding pusher 4 returns to the initial position, the air compressor 9 is started. The air conveyed by the air compressor 9 is ejected through the air holes 8 to separate the cellulose wound on the rack 422 and return it to the fiber cake 17.

[0054] The embodiment of the present application discloses a method for feeding a loose fiber cake. Referring to Figure 1 , the method for feeding a loose fiber cake uses a feeding device for a loose fiber cake, and further includes:

[0055] S1: Use a hoisting machine to hoist the fiber cake 17 onto the placing plate 6. Subsequently, adjust the height of the placing plate 6 through the second driving member to adjust the height of the top of the fiber cake 17, so that the top of the fiber cake 17 is within the action range of the feeding pusher 4;

[0056] S2: Drive the feeding pusher 4 to slide through the first driving member. The feeding pusher 4 scrapes the fiber layer on the top of the fiber cake 17 and drives the fiber layer into the fiber opening machine 3;

[0057] S3: After the feeding pusher 4 enters the fiber cake 17, drive the mounting rod 421 to reciprocate and slide through the third driving member. The mounting rod 421 drives the rack 422 to slide, and the rack 422 slides to tear the fiber layer on the surface layer of the fiber cake 17 to separate the fiber layer and the fiber cake 17;

[0058] S4: When the feeding pusher 4 returns to the initial position, the air supply device sends air into the rack 422 and discharges it through the air holes 8. The discharged air acts on the fiber wound on the rack 422 to separate the fiber from the rack 422;

[0059] S5: Then drive the placing plate 6 to rise through the second driving member. The placing plate 6 drives the fiber cake 17 to rise to the action range of the feeding pusher 4.

[0060] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
