[0014] A processing method for a depilatory drawing frame for silk spinning, the specific steps of the method are as follows:

[0015] Step 1: When processing the fiber strip, it is necessary to first move the second winding roller with the unprocessed fiber strip wound on it to the surface of the base, and then pass the fiber strip around multiple fixed rods and through the stretching mechanism, the cutting mechanism and the drawing frame body before being wound by the first winding roller;

[0016] Step 2: The stretching mechanism will stretch the fiber sliver to make the fiber sliver in a straightened state;

[0017] Step 3: The cutting mechanism will cut off the lint on the surface of the fiber sliver;

[0018] Step 4: When the lint that is difficult to cut moves to the position of the cutting mechanism, the lint that is difficult to cut will cross the cutting mechanism, and the switching mechanism will act on the standby cutting mechanism to perform standby cutting on the lint during the process of the lint acting on the movement of the cutting mechanism;

[0019] Step 5: Subsequently, the main body of the drawing frame will process the fiber sliver, and the first winding roller will wind up the processed fiber sliver.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. During the process of processing the fiber sliver, the present invention uses the conveying roller to convey the fiber sliver, which is beneficial to making the part of the fiber sliver inside the protective shell be in a stretched and gathered state, so as to facilitate the subsequent cutting of the protruding lint on the surface of the fiber sliver, and avoid the fiber sliver being in a relatively fluffy state when it moves into the protective shell. When cutting the lint on the surface of the fiber sliver, it is easy to damage the fiber sliver itself, thus affecting the subsequent processing of the fiber sliver. And the first cutter and the second cutter are used to cut off the lint on the surface of the fiber sliver. The first cutter moves to act on the movement of the second cutter and cut off the lint on the surface of the fiber sliver, which is beneficial to cutting off different lint on the surface of the fiber sliver, ensuring the treatment of the fiber sliver, and avoiding that during the process of treating the lint on the surface of the fiber sliver, due to the decrease in the sharpness of the first cutter or the relatively tight adhesion of the lint, the lint on the surface of the fiber sliver cannot be cut off, thus affecting the subsequent processing of the fiber sliver.

[0022] 2. During the process of removing the surface lint of the sliver in the present invention, when the first cutter cannot remove the surface lint of the sliver, the surface lint of the sliver will act on the first cutter to move. The first cutter will drive the second cutter to move together through the first mounting plate, the push rod and the second mounting plate. The second cutter will drive the second guide rod to move in the second chute. Subsequently, when the second guide rod moves to the position of the limit rod, the guide rod will squeeze and move over the limit rod from the bottom of the limit rod, and the limit rod will limit the guide rod, so that the second cutter can maintain the closed state, ensuring the removal of the surface lint of the sliver. When the first mounting plate resets, when the first mounting plate moves to the position of the extension rod, it will drive the extension rod to move together. The extension rod will move upward under the action of the third guide groove. The extension rod and the limit rod will move upward under the action of the third guide groove, and the limit rod will move above the second guide groove. The second guide rod and the second mounting plate will return to their original positions, which is beneficial to keeping the two second cutters closed during the process when the first cutter has not re-closed after merging, thus ensuring the removal of the surface lint of the sliver, and avoiding that when the two first cutters return to their original positions and separate, the second cutter cannot maintain the closed state, so that the surface lint of the sliver cannot be removed, affecting the subsequent processing of the sliver.

[0023] 3. During the process of removing the surface lint of the sliver in the present invention, the surface lint of the sliver will drive the first cutter and the first mounting plate to move together. The first mounting plate will drive the second mounting plate and the second guide rod to move through the push rod. The second guide rod will drive the first arc plate to move towards the sliver side under the action of the second guide groove. The first arc plate will drive the first rotating shaft and the first gear to move together. The first gear will drive the first rotating shaft and the first driving wheel to rotate together under the action of the first rack. The first driving wheel will act on the second cutter to rotate during the merging process. The second cutter can remove the surface lint of the sliver during the rotational merging process, which is beneficial to enhancing the removal effect of the second cutter on the surface lint of the sliver, and can more quickly remove the surface lint of the sliver. Moreover, the rotation of the two second cutters can cover the positions where the two second cutters are not completely closed, avoiding omission. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

A switching mechanism is provided inside the cutting mechanism, and the switching mechanism is used to switch the spare cutting mechanism to cut the lint on the surface of the fiber strips when the lint that is difficult to cut on the surface of the fiber strips passes over the cutting mechanism;

[0041] The cutting mechanism includes a protective shell 7, the protective shell 7 is fixedly connected to the surface of the support plate 4, a first through hole 8 is opened on the surface of the protective shell 7, the first through hole 8 penetrates the protective shell 7, a first mounting plate 9 is provided inside the protective shell 7, a second through hole 10 is opened on the surface of the first mounting plate 9, two arc-shaped first cutting knives 11 are provided on the surface of the first mounting plate 9, the two first cutting knives 11 form a cylindrical shape, the end of the first cutting knife 11 inclines towards the second through hole 10, and the end of the first cutting knife 11 extends to the position of the first through hole 8;

[0042] The stretching mechanism includes two fixing plates 12, the two fixing plates 12 are respectively fixedly connected to the left and right surfaces of the protective shell 7, two rotating rods 13 are rotatably connected between the fixing plates 12 and the support plate 4, two conveying rollers 14 are fixedly connected to the two rotating rods 13, the two conveying rollers 14 are in contact with each other, and annular conveying grooves 15 are opened on the surfaces of the two conveying rollers 14;

[0043] :The spare cutting mechanism includes a second mounting plate 16, which is arranged on the inner wall surface of the protective housing 7. A third through port 17 is formed on the surface of the second mounting plate 16. Two arc-shaped second cutting blades 18 are arranged on the surface of the second mounting plate 16. The two second cutting blades 18 are located on the side of the first cutting blade 11 close to the drawing frame main body 2. The ends of the two second cutting blades 18 pass through the second through port 10 and extend into the first cutting blade 11;

[0044] The switching mechanism includes a plurality of first guide rods 19, which are arranged on the surface of the first cutting blade 11. A plurality of first guide grooves 20 are formed on the inner wall surface of the protective housing 7. The first guide grooves 20 are inclined away from the second through port 10. When the two first cutting blades 11 are in a combined state, the first guide rods 19 extend into the first guide grooves 20. Both the first mounting plate 9 and the second mounting plate 16 are elastically slidable on the inner wall surface of the protective housing 7. A plurality of second guide rods 21 are arranged on the surface of the second cutting blade 18. A plurality of second guide grooves 22 are formed on the inner wall surface of the protective housing 7. The second guide grooves 22 are inclined towards the third through port 17. When the two second cutting blades 18 are in a separated state, the second guide rods 21 extend into the second guide grooves 22. A push rod 23 is fixedly connected to the side of the first mounting plate 9 close to the second mounting plate 16;

[0045] During the processing of the sliver, the second winding roller 6 wound with the unprocessed sliver needs to be placed on the surface of the base 1 first. The second winding roller 6 will be located below the support plate 4. Subsequently, after the sliver bypasses multiple fixing rods 5 and passes through the conveying groove 15 between the two conveying rollers 14, the sliver will continue to pass through the first through-port 8 and pass through the protective shell 7. After passing through the protective shell 7, the sliver will extend into the drawing frame main body 2 for processing. The processed sliver will be wound by the first winding tube. During the processing of the sliver, the sliver will pass through the conveying groove 15 on the surface of the conveying roller 14. When the rotating rod 13 drives the conveying roller 14 to rotate to convey the sliver, the conveying groove 15 will clamp and convey the sliver. When the conveying grooves 15 on both sides of the protective shell 7 clamp and convey the sliver, the sliver between the conveying grooves 15 on both sides of the protective shell 7 will be stretched and in a gathered state, which is beneficial to making the part of the sliver inside the protective shell 7 in a stretched and gathered state, so as to facilitate the subsequent removal of the protruding fluff on the surface of the sliver and avoid the sliver being in a relatively fluffy state when it moves into the protective shell 7. When removing the fluff on the surface of the sliver, it is easy to damage the sliver itself, thus affecting the subsequent processing of the sliver. When the sliver moves through the first through-port 8 and between the two first cutting knives 11, the sliver will pass between the two first cutting knives 11. The ends of the two first cutting knives 11 will incline towards the surface of the sliver. During the movement of the sliver, the protruding fluff on the surface of the sliver will protrude outside the two first cutting knives 11, and the first cutting knives 11 will cut off the fluff on the surface of the sliver. Subsequently, when there is fluff tightly attached to the surface of the sliver, the first cutting knives 11 cannot cut off the fluff tightly attached to the surface of the sliver. When the fluff moves to the position of the first cutting knives 11, the first cutting knives 11 and the first mounting plate 9 will be driven by the fluff to move towards the second mounting plate 16. The movement of the first cutting knives 11 will drive the first guide rods 19 to move in the first guide grooves 20. The two first cutting knives 11 will move towards the upper and lower sides respectively under the action of the first guide rods 19 and the first guide grooves 20, and the two first cutting knives 11 will open. During the movement of the first mounting plate 9, the first mounting plate 9 will drive the push rod 23 to move together. The push rod 23 will act on the second mounting plate 16 and the second cutting knives 18 to move together. The second cutting knives 18 will drive the second guide rods 21 to move in the second guide grooves 22. The second guide rods 21 and the second guide grooves 22 will act on the two second cutting knives 18 to move towards each other. The two second cutting knives 18 will gradually approach and merge into a cylindrical shape. Subsequently, when the sliver moves to the position of the second cutting knives 18, the sharper second cutting knives 18 will cut off the fluff on the surface of the sliver. The present invention sets the second cutting knives 18 as a backup. When the first cutting knives 11 cannot cut off the fluff on the surface of the sliver, the movement of the first cutting knives 11 is used to act on the movement of the second cutting knives 18 and cut off the fluff on the surface of the sliver, which is beneficial to cutting off different fluff on the surface of the sliver and ensuring the treatment of the sliver.This prevents the first cutter 11 from being unable to remove the lint on the surface of the fiber strip during processing, as the sharpness of the cutter 11 decreases or the lint is tightly attached, thereby affecting subsequent processing of the fiber strip.

[0046] In the process of cutting off the hair particles on the surface of the fiber strip, the movement of the first cutter 11 will drive the second cutter 18 to move together, but the second cutter 18 cannot maintain a merged state. As a further solution of the present invention, the inner wall surface of the protective shell 7 is elastically slidably connected to the limit rod 24, the bottom of the limit rod 24 is an inclined surface, and the bottom of the limit rod 24 extends to the position of the second guide groove 22. The end of the limit rod 24 is fixedly connected with an L-shaped extension rod 25, and the extension rod 25 extends to the side of the first mounting plate 9 away from the second mounting plate 16. The extension rod 25 is retractable near the side of the limit rod 24. An inclined third guide groove 26 is provided on the inner wall surface of the protective shell 7, and the side of the extension rod 25 slides in the third guide groove 26. A clearance notch 27 is provided on the side of the second mounting plate 16 close to the inner wall of the protective shell 7 corresponding to the position of the limit rod 24;

[0047] In the process of cutting off the hair particles on the surface of the fiber strip, when the first cutter 11 cannot cut off the hair particles on the surface of the fiber strip, the hair particles on the surface of the fiber strip will act on the first cutter 11 to move, and the first cutter 11 will drive the second cutter 18 to move together through the first mounting plate 9, the push rod 23 and the second mounting plate 16, and the second cutter 18 will drive the second guide rod 21 to move in the second slide groove 35, and the limit rod 24 will pass through the mounting plate through the clearance gap 27. Then, when the second guide rod 21 moves to the position of the limit rod 24, the guide rod will squeeze and pass over the limit rod 24 from the bottom of the limit rod 24. The limit rod 24 will limit the guide rod, so that the second cutter 18 can remain in a merged state, ensuring the cutting of the hair particles on the surface of the fiber strip. During resetting, when the first mounting plate 9 moves to the position of the extension rod 25, it will drive the extension rod 25 to move together, and the extension rod 25 will move upward under the action of the third guide groove 26. The extension rod 25 and the limit rod 24 will move upward under the action of the third guide groove 26, and the limit rod 24 will move to above the second guide groove 22. The second guide rod 21 and the second mounting plate 16 will return to their original positions, which is conducive to the two second cutters 18 being able to remain closed after being merged while the first cutter 11 is not re-merged, thereby ensuring the removal of the hair particles on the surface of the fiber strip, and avoiding the second cutter 18 being unable to remain merged during the process of the two first cutters 11 returning to their original positions and separating, thereby failing to remove the hair particles on the surface of the fiber strip, affecting the subsequent processing of the fiber strip.

[0048] In the process of treating the surface fluff of the fiber sliver, it is not convenient to directly merge the two second cutting knives 18 to cut the surface fluff of the fiber sliver. As a further solution of the present invention, a first sliding groove 28 is formed on the surface of the second mounting plate 16. A first arc-shaped plate 29 is elastically slidably connected in the first sliding groove 28. The second cutting knife 18 slides on the surface of the first arc-shaped plate 29. A first rack 30 is fixedly connected in the first sliding groove 28. A first through hole 31 is formed on the surface of the first arc-shaped plate 29. A first rotating shaft 32 is rotatably connected in the first through port 8. The first rotating shaft 32 extends into the first sliding groove 28. A first gear 33 and a first driving wheel 34 are fixedly connected to the surface of the first rotating shaft 32. The first gear 33 is located in the first sliding groove 28 and meshes with the first rack 30. The first driving wheel 34 is located in the first through hole 31. The first driving wheel 34 is in contact with the surface of the second cutting knife 18;

[0049] In the process of cutting the surface fluff of the fiber sliver, the surface fluff of the fiber sliver will drive the first cutting knife 11 and the first mounting plate 9 to move together. The first mounting plate 9 will drive the second mounting plate 16 and the second guiding rod 21 to move through the push rod 23. The second guiding rod 21 will drive the first arc-shaped plate 29 to move toward the side close to the fiber sliver under the action of the second guiding groove 22. The first arc-shaped plate 29 will drive the first rotating shaft 32 and the first gear 33 to move together. The first gear 33 will drive the first rotating shaft 32 and the first driving wheel 34 to rotate together under the action of the first rack 30. The first driving wheel 34 will act on the second cutting knife 18 to rotate during the merging process. The second cutting knife 18 can cut the surface fluff of the fiber sliver during the rotational merging process, which is beneficial to enhancing the cutting effect of the second cutting knife 18 on the surface fluff of the fiber sliver, and can more quickly cut the surface fluff of the fiber sliver. Moreover, the rotation of the two second cutting knives 18 can cover the positions where the two second cutting knives 18 are not completely closed, avoiding omission.

[0050] During the process of removing the fluff on the surface of the sliver, the sharpness of the first cutter 11 for long-term cutting at a fixed position will decrease. As a further solution of the present invention, a second chute 35 is formed on the surface of the first mounting plate 9. A second arc-shaped plate 36 is elastically slidably connected in the second chute 35. The first cutter 11 slides on the surface of the second arc-shaped plate 36. A second rack 37 is fixedly connected in the second chute 35. A second through hole 38 is formed on the surface of the second arc-shaped plate 36. A second rotating shaft 39 is rotatably connected in the second through hole 38. A second driving wheel 40 is fixedly connected to the surface of the second rotating shaft 39. The second driving wheel 40 is located in the second through hole 38. The second driving wheel 40 is in contact with the surface of the first cutter 11. A second gear 41 is rotatably connected to the surface of the second driving wheel 40. The second gear 41 is located in the second chute 35. The second gear 41 meshes with the second rack 37. An annular card slot 42 is formed on the surface of the second gear 41. The edge of the card slot 42 is tooth-shaped. One side of the edge of the card slot 42 with teeth is a slope. An elastically telescopic limiting rod 43 is fixedly connected to the surface of the second rotating shaft 39. The limiting rod 43 is located in the card slot 42. One side of the end of the limiting rod 43 is a slope;

[0051] During the process of removing the fluff on the surface of the sliver, when the fluff on the surface of the sliver drives the first cutter 11 and the first mounting plate 9 to move, the first guiding rod 19 and the second arc-shaped plate 36 will move away from the sliver under the action of the first guiding groove 20. The second rotating shaft 39 and the second gear 41 will move together. During the rotation of the second gear 41, the limiting rod 43 will engage with the edge of the card slot 42. The second gear 41 will drive the second rotating shaft 39 and the second driving wheel 40 to rotate together through the limiting rod 43. The second driving wheel 40 will act on the first cutter 11 to rotate a certain angle, which is beneficial to switching the cutting position of the first cutter 11 and ensuring the cutting effect of the first cutter 11. Subsequently, during the process of the first mounting plate 9 returning to its original position, the second gear 41 rotates in the reverse direction, and the limiting rod 43 will move in the card slot 42. The limiting rod 43 will contract and rotate under the action of the slope on the edge of the card slot 42.

[0052] During the process of processing the fluff on the surface of the sliver, the fluff cut off by the first cutter 11 will fall onto the surface of the sliver during the movement of the first cutter 11. As a further solution of the present invention, a sweeping brush 44 is fixedly connected in the first through port 8;

[0053] During the process of removing the fluff on the surface of the sliver, the fluff cut off by the first cutter 11 will adhere to the surface of the sweeping brush 44, preventing the cut-off fluff from falling off and re-adhering to the surface of the sliver during the movement of the first cutter 11, thereby affecting the subsequent processing of the sliver.

[0054] A processing method of a carding machine for removing fluff in silk spinning, the specific steps of the method are as follows:

[0055] Step 1: When processing the fiber sliver, the second winding roller 6 wound with the unprocessed fiber sliver needs to be moved to the surface of the base 1 first. Subsequently, the fiber sliver is wound around multiple fixing rods 5 and passes through the stretching mechanism, the cutting mechanism and the drawing frame main body 2 and then is wound by the first winding roller 3;

[0056] Step 2: The stretching mechanism stretches the fiber sliver to make the fiber sliver in a straightened state;

[0057] Step 3: The cutting mechanism cuts off the fluff on the surface of the fiber sliver;

[0058] Step 4: When the fluff that is difficult to cut moves to the position of the cutting mechanism, the fluff that is difficult to cut will cross the cutting mechanism, and the switching mechanism will act on the spare cutting mechanism to perform spare cutting on the fluff during the process of the fluff acting on the movement of the cutting mechanism;

[0059] Step 5: Subsequently, the drawing frame main body 2 processes the fiber sliver, and the first winding roller 3 winds the processed fiber sliver.
