Description

Technical Field

[0001] The invention relates to the technical field of carding machines, in particular to a flexible carding mechanism and a damage control method of a cashmere carding machine. Background Art

[0002] Cashmere specifically refers to the dense undercoat of hair that grows at the base of goats' skin in winter to protect them from the cold. However, raw cashmere is not a "pure fiber" and is contaminated with impurities such as sand, grass scraps, and dander. If used directly for textiles, these impurities can cause yarn breakage and fabric pilling. Therefore, the raw cashmere must be separated from the high-quality long cashmere fibers through a carding machine to obtain pure cashmere fibers that meet textile requirements.

[0003] The carding mechanism of existing carding machines is mostly composed of rollers, cylinder rollers, doffer rollers and licker-in. Its working principle is as follows: the pretreated cashmere is pulled by the rollers to the licker-in, and the impurities and short fibers are initially separated by the impact of the licker-in needle cloth and the centrifugal force. Subsequently, the cashmere fibers are transferred to the surface of the cylinder roller. The cylinder roller and the doffer roller rotate at a differential speed, and the short fibers and fine impurities are further removed by multiple combing of the needle cloth. Finally, the combed cashmere is transferred to the cleaning area, where cleaning and drying complete the cashmere carding process.

[0004] In the actual production process, cashmere fibers are prone to abnormal attachment to the cloth needles on the outside of the doffer roller. As the doffer roller continues to rotate, these attached fibers will gradually accumulate due to mechanical action to form a tangled layer, resulting in a dynamic imbalance of the fiber load in the combing area. The initial manifestation is a reduction in the effective combing area and a decrease in combing efficiency. As the thickness of the tangled layer increases, the mechanical stress on the fibers during the transfer process intensifies, which is more likely to cause structural damage problems such as fiber breakage and increased hair particles, ultimately affecting product quality. Therefore, the present application proposes a flexible combing mechanism and damage control method for a cashmere carding machine. Summary of the Invention

[0028] 1. The present invention utilizes a transverse plate and flexible spherical needles, coordinated with the periodic expansion and contraction control of an adjustment mechanism, to achieve synergistic optimization of efficient combing and entanglement removal. When the needles initially protrude, the flexible spherical tips reduce fiber puncture damage and improve combing efficiency. When the doffer roller rotates to a set number of turns, the reset assembly pulls the transverse plate back, and the needles retract to simultaneously clean the entangled cashmere on the surface, avoiding fiber damage caused by accumulated entanglement layers. This design dynamically balances combing strength and fiber protection, significantly improving the equipment's continuous operation stability and product quality.

[0029] 2. The present invention is powered by a small blower and a battery, and cooperates with the through-hole design inside the horizontal plate and the cloth needle to link the baffle plate, coil spring and guide wheel and other structures to achieve precise control of airflow: under normal circumstances, the baffle plate closes the through-hole to prevent airflow loss; only when the horizontal plate rotates out of engagement with the doffer roller, the traction rope pulls the baffle plate to swing open the through-hole, and the blower blows air through the through-hole to the outside of the cloth needle to clean the cashmere. After cleaning is completed, the coil spring resets and closes the through-hole. This design only concentrates the airflow during cleaning to avoid dispersion, thereby significantly enhancing the efficiency of cashmere entanglement cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example

[0043] like Figure 1 and Figure 2 As shown, the flexible combing mechanism of the cashmere carding machine proposed in the present invention includes a cylinder roller 1, and the two ends of the cylinder roller 1 are rotatably connected to a connecting frame 2. A motor 3 for driving the cylinder roller 1 to rotate is installed on the outside of the connecting frame 2. When the motor 13 is running, its transmission shaft will drive the cylinder roller 1 to rotate synchronously. It also includes: two groups of relatively arranged lifting frames 4 and a doffer roller 5 located between the two groups of lifting frames 4. The lifting frames 4 are provided with a motor 2 6 for driving the doffer roller 5 to rotate. When the motor 2 6 is running, it will drive the doffer roller 5 to rotate, and the doffer roller 5 and the cylinder roller 1 rotate in opposite directions, and the rotation speed of the doffer roller 5 is lower than the rotation speed of the cylinder roller 1. At this time, the cashmere located between the cylinder roller 1 and the doffer roller 5 will move under the traction of the cylinder roller 1, and the rotation speed of the doffer roller 5 is slower than that of the cylinder roller 1. The doffer roller 5 will pull and comb the cashmere. It should be noted that the cylinder roller 1 and the doffer roller 5 are both conventional technologies in the existing carding machine, and will not be elaborated in detail.

[0044] As an implementation method, Figure 1 and Figure 2 As shown, the flexible combing mechanism in this embodiment also includes a lifting mechanism, which is used to adjust the height of the doffer roller 5 and is installed on the lifting frame 4; when the lifting mechanism is running, it can drive the doffer roller 5 to change its height. When facing different types of cashmere, the interval between the doffer roller 5 and the cylinder roller 1 can be adjusted in real time through the lifting mechanism. This dynamic adjustment method can better adapt to the working scenarios required by different cashmere.

[0045] Further, such as Figure 3-Figure 6 As shown, the flexible combing mechanism in this embodiment also includes multiple groups of transverse plates 7, and the multiple groups of transverse plates 7 are distributed inside the doffer roller 5. The inner wall of the doffer roller 5 is provided with a slide groove 28 corresponding to the transverse plate 7, and the slide groove 28 is slidably connected to the transverse plate 7. The side of the transverse plate 7 is fixed with multiple groups of cloth needles 8, and the multiple groups of cloth needles 8 protrude outward from the inside of the doffer roller 5, which can increase the friction between the doffer roller 5 and the cashmere, thereby improving its efficiency during combing. The cloth needle 8 is spherical at one end away from the transverse plate 7, and the cloth needle 8 is made of flexible material. The spherical shape combined with the flexible material design can reduce fiber puncture damage when the cloth needle 8 contacts the cashmere.

[0046] As an implementation method, Figure 4 、 Figure 5 and Figure 6As shown, the adjusting mechanism includes a moving component and a reset component, wherein: the moving component is used to drive the cloth needle 8 to extend out of the inside of the doffer roller 5 when the doffer roller 5 rotates. In the initial state, the moving component will squeeze the cross plate 7 so that the cross plate 7 fits the inner wall of the doffer roller 5. At this time, the cloth needle 8 is in a state of protruding from the inside of the doffer roller 5. The cloth needle 8 will comb the cashmere synchronously with the rotation of the doffer roller 5. The reset component is used to pull the cloth needle 8 back to the inside of the doffer roller 5 when the doffer roller 5 rotates to a certain number of circles. When the doffer roller 5 rotates to a certain number of circles, the reset component will drive a group of cross plates 7 and multiple groups of cloth needles 8 fixed to the group of cross plates 7 to reset. The cross plate 7 will move along the slide groove 28 at this time to make the cloth needle 8 be in a state inside the doffer roller 5. When resetting, the cloth needle 8 will move toward the inside along the doffer roller 5, and the cashmere entangled or attached to the outside of the cloth needle 8 will be affected by the cloth. The cloth needles 8 are affected by the doffer roller 5 and move synchronously. When the cashmere moves, it will eventually touch the outside of the doffer roller 5, and as the cloth needles 8 continue to move, the cashmere is blocked by the doffer roller 5 and cannot continue to move, thereby breaking away from the outside of the cloth needles 8, solving the problem of cashmere entanglement, and effectively preventing the cashmere fibers from being entangled on the outside of the cloth needles 8, gradually accumulating to form a entanglement layer, resulting in a dynamic imbalance of the fiber load in the combing area and damage to the cashmere fibers. After the cloth needles 8 are reset to the inside of the doffer roller 5, the group of transverse plates 7 and cloth needles 8 are again affected by the moving component, and the cloth needles 8 protrude again, while the other group of transverse plates 7 and cloth needles 8 are affected by the reset component, and the above-mentioned actions occur in the same way. Therefore, when the doffer roller 5 rotates one circle, it can ensure that each group of transverse plates 7 and cloth needles 8 can clean the cashmere wrapped around the outside, thereby improving the continuous operation capability of the equipment.

[0047] At this time, if Figure 4 As shown, the blowing mechanism is connected to the limiting column 13, which is used to blow out the wind inside the doffer roller 5. The blowing mechanism is located inside the limiting column 13. The blowing mechanism can transmit the outside air into the interior of the cloth needle 8, and then blow it out from the end of the cloth needle 8 away from the horizontal plate 7, so that its airflow can cooperate with the cloth needle 8 to further comb the cashmere, and under the action of the airflow, the cashmere wrapped around the outside of the cloth needle 8 can also be blown off, and the cashmere can be mechanically cleaned by moving the cloth needle 8 to the interior of the doffer roller 5. The combination of the two has a better effect.

[0048] As an implementation method, Figure 2 As shown, the lifting mechanism includes a limit block 10, a pair of limit rods 11 and a cylinder 12. The lifting mechanism is described in detail below:

[0049] The limit block 10 is arranged inside the lifting frame 4, and both ends of a pair of limit rods 11 are fixed to the inner wall of the lifting frame 4, and the limit rods 11 pass through the limit block 10. The pair of limit rods 11 can limit the limit block 10, ensuring that the limit block 10 can only move up and down along the limit rods 11. It should be noted that the motor 2 6 is installed on the outside of the limit block 10. Therefore, when the limit block 10 moves, it will not only drive the doffer roller 5 to move, but also drive the motor 2 6 to move, ensuring that the output end of the motor 2 6 can always drive the doffer roller 5 to move. The roller 5 rotates, and the cylinder 12 is installed on the top of the lifting frame 4. The output end of the cylinder 12 is fixedly connected to the top of the limit block 10. When the cylinder 12 is running, it can drive the limit block 10 to move and adjust it to the specified position. The limit block 10 then drives the doffer roller 5 to adjust the height. It should be noted that the cylinder 12 is externally connected to an air compressor, and the air compressor is fixed on the lifting frame 4 (the air compressor is not shown in the figure). The compressed air enters the rodless cavity of the cylinder 12, pushing the piston to move, and the piston drives the piston rod to output linear reciprocating motion.

[0050] Among them, Figure 4 、 Figure 5 and Figure 6 As shown, the moving assembly includes a limiting column 13, a connecting rod 14, a pair of concave rods 15 and a pair of guide columns 16. The moving assembly is described in detail below:

[0051] The limit post 13 is located inside the doffer roller 5, and the connecting rod 14 is fixed to the limit post 13. The end of the connecting rod 14 away from the limit post 13 passes through the doffer roller 5 and extends to the outside of the doffer roller 5. A pair of concave rods 15 are fixed to the outside of the connecting rod 14, and the end of the concave rod 15 away from the connecting rod 14 is fixed to the limit block 10. The concave rod 15 and the connecting rod 14 can both support the limit post 13. When the limit block 10 moves in height, the concave rod 15 and the connecting rod 14 can drive the limit post 13 to move synchronously, ensuring that the limit post 13 is always inside the doffer roller 5 and moves synchronously with the height movement of the doffer roller 5. A pair of guide posts 16 are fixed to the cross plate 7, and the guide posts 16 are in contact with the outside of the limit post 13. In the initial state, the guide posts 16 are squeezed by the limit post 13, thereby pushing a part of the cloth needle 8 to the outside of the doffer roller 5, presenting a convex state (such as Figure 5 As shown in the working state, when the doffer roller 5 rotates, the doffer roller 5 drives the transverse plate 7 to rotate synchronously, and the rotation of the transverse plate 7 drives the cloth needle 8 to make a circular motion with the doffer roller 5 as the center, thereby combing the cashmere.

[0052] In addition, if Figure 5 and Figure 6 As shown, the reset assembly includes a support block 17 and a pair of springs 18. The reset assembly is described in detail below:

[0053] The support block 17 is fixedly connected to the inner wall of the doffer roller 5, and the pair of springs 18 are fixedly connected to the transverse plate 7. The end of the spring 18 away from the transverse plate 7 is fixedly connected to the support block 17. When the limit column 13 applies an extrusion force to the guide column 16, the spring 18 is in a stretched state. As the cloth needle 8 makes a circular motion, the guide column 16 will reach the recessed position of the limit column 13 (such as Figure 6 The working state shown in the figure) is shown in the figure. At this time, the spring 18 releases its elastic potential energy, thereby pulling the cross plate 7 to move. The movement of the cross plate 7 drives the cloth needle 8 to move toward the inside of the doffer roller 5. The cloth needle 8 cooperates with the doffer roller 5 at this time to scrape off the cashmere wrapped around the outside of the cloth needle 8. Then, when the cloth needle 8 continues to move in a circular motion, the guide column 16 contacts the concave inclined surface of the limiting column 13. The limiting column 13 applies an extruding force to the guide column 16 again, so that the cloth needle 8 protrudes to the outside of the doffer roller 5 again, and the spring 18 is in a stretched state again.

[0054] It should be noted that if Figure 4 As shown, the blowing mechanism includes a small blower, a battery and a through hole 9. The blowing mechanism is described in detail below:

[0055] The small blower and the battery are both installed inside the limiting column 13. The battery is connected to the input end of the small blower. The battery provides a power source for the small blower. The through hole 9 is opened inside the horizontal plate 7 and the cloth needle 8. When the small blower is running, the air inside the doffer roller 5 will be discharged from the inside of the doffer roller 5 through the through hole 9. Since the through hole 9 is opened inside the horizontal plate 7 and the cloth needle 8, the airflow will impact the cashmere wrapped around the outside of the cloth needle 8 and blow away the cashmere at the end of the cloth needle 8. The battery and the small blower are both existing mature technologies and are not marked in the figure, so they will not be elaborated in detail.

[0056] As an implementation method, Figure 7 、 Figure 8 and Figure 9As shown, the transverse plate 7 is provided with multiple groups of blocking plates 19 corresponding to the through holes 9. When the transverse plate 7 and the doffer roller 5 are in contact, the blocking plates 19 and the transverse plate 7 are in contact, and the through holes 9 can be closed to avoid the loss of wind force. The rotating shaft of the blocking plate 19 is hinged with a side plate 20, and the top of the blocking plate 19 is fixedly connected with a top plate 21. A traction rope 22 is fixed between the top plate 21 and the doffer roller 5. When the transverse plate 7 moves out of contact with the doffer roller 5, it means that the cloth needle 8 is in the doffer roller. 5, to clean the cashmere. At this time, the movement of the horizontal plate 7 will drive the blocking plate 19 to move synchronously through the side plate 20. Due to the limited distance of the traction rope 22, when the blocking plate 19 moves, the traction rope 22 will cooperate with the doffer roller 5 to pull the top plate 21. The top plate 21 is subjected to force and drives the blocking plate 19 to swing. The swing of the blocking plate 19 will end the closure of the through hole 9. At this time, the air inside the doffer roller 5 will pass through the through hole 9 on the set of horizontal plates 7 to pass the air into the interior of the cloth needle 8, and then The wind impacts the entangled cashmere through the cloth needle 8, and a coil spring 23 is fixed between the rotating shaft of the side plate 20 and the blocking plate 19. When the blocking plate 19 swings, the coil spring 23 is also driven to deform, so that it generates elastic potential energy. A guide wheel 27 is fixed to the outer side of the horizontal plate 7. The guide wheel 27 is in contact with the traction rope 22. The guide wheel 27 can guide the traction position of the traction rope 22. When the horizontal plate 7 is in contact with the doffer roller 5 again, the traction rope 22 stops pulling the top plate 21. , the coil spring 23 will release the elastic potential energy, thereby driving the rotating shaft of the blocking plate 19 to reverse and reset, and the blocking plate 19 will then close the through hole 9 again. Through the above-mentioned structural design, it is achieved that the air flow channel of the through hole 9 can be opened only when the cross plate 7 is separated from the doffer roller 5 (the cloth needle 8 needs to enter the interior of the doffer roller 5 to clean the entangled cashmere), thereby increasing the airflow and avoiding the situation where the through holes 9 on the multiple groups of cross plates 7 are in a flow state under normal circumstances, which disperses the airflow and causes a small airflow.

[0057] In addition, if Figure 8 As shown, a groove 24 is provided at one end of the guide column 16 close to the limiting column 13, and a roller 25 is rotatably connected inside the groove 24. The roller 25 fits against the outer side of the limiting column 13, and the opening of the groove 24 provides an installation space for the roller 25. When the guide column 16 directly contacts the limiting column 13, the friction is too large and damage is easily caused. The setting of the roller 25 can rotate along the limiting column 13, thereby reducing friction, reducing damage, and improving the service life of the device.

[0058] Further, such as Figure 8 As shown, a rubber pad 26 is glued to the bottom end of the blocking plate 19, and the rubber pad 26 is in contact with the horizontal plate 7. The rubber pad 26 can increase the sealing performance when the blocking plate 19 contacts the horizontal plate 7, and can also play a buffering role when the blocking plate 19 contacts the horizontal plate 7.

[0059] A damage control method for a cashmere carding machine, the method comprising the following steps:

[0060] S1: In the initial state, the guide column 16 is squeezed by the limiting column 13, thereby pushing a portion of the cloth needle 8 to the outside of the doffer roller 5, presenting a convex state;

[0061] S2: When the doffer roller 5 rotates, the doffer roller 5 drives the cross plate 7 to rotate synchronously, and the rotation of the cross plate 7 drives the cloth needles 8 to make a circular motion with the doffer roller 5 as the center, thereby combing the cashmere;

[0062] S3: When the limiting column 13 applies an extrusion force to the guide column 16, the spring 18 is in a stretched state. As the cloth needle 8 makes a circular motion, the guide column 16 reaches the recess of the limiting column 13;

[0063] S4: At this time, the spring 18 releases its elastic potential energy, thereby pulling the transverse plate 7 to move, and the movement of the transverse plate 7 drives the cloth needle 8 to move toward the inside of the doffer roller 5;

[0064] S5: The cashmere is blocked by the doffer roller 5 and cannot continue to move with the cloth needle 8, thereby separating from the outside of the cloth needle 8, thereby effectively preventing the cashmere fibers from being entangled on the outside of the cloth needle 8 and gradually accumulating to form an entanglement layer, resulting in a dynamic imbalance of the fiber load in the combing area and damage to the cashmere fibers.

[0065] The implementation principle of the present invention is as follows: when the motor 1 3 is running, its transmission shaft will drive the cylinder roller 1 to rotate synchronously, and when the motor 2 6 is running, it will drive the doffer roller 5 to rotate, and the directions of rotation of the doffer roller 5 and the cylinder roller 1 are opposite. At this time, the cashmere between the cylinder roller 1 and the doffer roller 5 will move under the traction of the cylinder roller 1, and the rotation speed of the doffer roller 5 is slower than that of the cylinder roller 1. The doffer roller 5 will pull and comb the cashmere. When the cylinder 12 is running, it can drive the limit block 10 to move and adjust it to the specified position. The limit block 10 then drives the doffer roller 5 to adjust the height. In the initial state, the guide column 16 is squeezed by the limit column 13, thereby pushing a part of the cloth needle 8 to the outside of the doffer roller 5, presenting a convex state. When the doffer roller 5 rotates, the doffer roller 5 will drive the cross plate 7 to rotate synchronously, and the cross plate The plate 7 rotates and drives the cloth needle 8 to make a circular motion with the doffer roller 5 as the center, thereby combing the cashmere. When the limit column 13 applies an extrusion force to the guide column 16, the spring 18 is in a stretched state. As the cloth needle 8 makes a circular motion, the guide column 16 reaches the recessed position of the limit column 13. At this time, the spring 18 releases its elastic potential energy, thereby pulling the cross plate 7 to move. The movement of the cross plate 7 drives the cloth needle 8 to move toward the inside of the doffer roller 5. The cloth needle 8 cooperates with the doffer roller 5 at this time to scrape off the cashmere wrapped around the outside of the cloth needle 8. Then, when the cloth needle 8 continues to move in a circular motion, the guide column 16 contacts the recessed inclined surface of the limit column 13. The limit column 13 applies an extrusion force to the guide column 16 again, so that the cloth needle 8 protrudes to the outside of the doffer roller 5 again, and the spring 18 is in a stretched state again.

[0066] When the small blower is running, the air inside the doffer roller 5 will be discharged from the inside of the doffer roller 5 through the through hole 9. Since the through hole 9 is opened inside the cross plate 7 and the cloth needle 8, the airflow will impact the cashmere wrapped around the outside of the cloth needle 8 and blow away the cashmere at the end of the cloth needle 8.

[0067] When the horizontal plate 7 and the doffer roller 5 are in contact, the blocking plate 19 is in contact with the horizontal plate 7, which can close the through hole 9 and avoid the loss of wind force. When the horizontal plate 7 moves out of contact with the doffer roller 5, it means that the cloth needle 8 is inside the doffer roller 5 to clean the cashmere. At this time, the movement of the horizontal plate 7 will drive the blocking plate 19 to move synchronously through the side plate 20. Due to the limited distance of the traction rope 22, when the blocking plate 19 moves, the traction rope 22 will cooperate with the doffer roller 5 to pull the top plate 21. The force on the top plate 21 will drive the blocking plate 19 to swing, blocking The swing of plate 19 will end the closing of the through hole 9. At this time, the air inside the doffer roller 5 will pass through the through holes 9 on the group of horizontal plates 7 to transmit the air into the interior of the cloth needles 8, and then the cloth needles 8 will impact the entangled cashmere with the wind force. When the blocking plate 19 swings, it will also drive the coil spring 23 to deform, causing it to generate elastic potential energy. When the horizontal plate 7 and the doffer roller 5 are fitted together again, the traction rope 22 stops pulling the top plate 21, and the coil spring 23 will release the elastic potential energy, thereby driving the rotating shaft of the blocking plate 19 to reverse and reset, and the blocking plate 19 will then close the through hole 9 again.

[0068] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
