Description

Technical Field

[0001] This utility model relates to the field of carding machine equipment technology, and in particular to an anti-tangling mechanism for silk floss carding machine. Background Technology

[0002] Silk floss is a flocculent material made from the scraps of silkworm cocoons and the floating silk on the surface of the cocoon shell. It is processed through processes such as refining, dissolving sericin, and loosening the fibers. In ancient times, people used silk floss to fill their clothes as a way to keep warm or to make silk quilts. In modern technology, a carding machine is used to process the silk floss raw material. The carding machine is a spinning machine that sorts the pre-processed spinning raw material into single fibers, forms a thin layer of mesh fibers, and then gathers them into fiber strips.

[0003] A search revealed Chinese Patent Publication No. CN219709674U, which discloses an anti-tangling yarn combing machine. The machine includes a combed fiber strip that is discharged after operation. The fiber strip is fixed on a take-up roller, and a motor is started. The rotation of the motor's output shaft drives the take-up roller to rotate, thus achieving the effect of winding the fiber strip. Simultaneously, through the cooperation of a rectangular rod, transmission shaft, sprocket, chain, and reciprocating screw, a moving seat is driven to reciprocate left and right, achieving uniform winding of the fiber strip and preventing yarn tangling during the winding process.

[0004] In actual use, the aforementioned carding machine requires feeding the loosened silk floss material through the opener into the rollers, pressure rollers, or curtains via a conveyor belt. However, the placement of the material on the conveyor belt often relies on manual operation, resulting in varying amounts of material at different locations on the conveyor belt. This can lead to situations where the fiber layer is too thick in some areas. When excessive fiber enters the feeding rollers or pressure rollers, it can easily accumulate due to insufficient clamping force or speed mismatch, posing a risk of fiber entanglement on the surface of the rollers or carding cloth, forming "knots." In severe cases, this can block the feeding channel, requiring machine shutdown for cleaning and impacting production efficiency. Therefore, an anti-entanglement mechanism silk floss carding machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-tangling mechanism for silk floss combing machines, which aims to improve the problem in the prior art where the silk floss raw material is placed too thickly on the conveyor belt, posing a risk of fibers tangling on the roller or carding cloth surface.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tangling mechanism for silk floss combing, comprising a housing, a combing mechanism disposed inside the housing, a fixed frame fixedly connected to the left side of the housing, a conveyor belt disposed inside the fixed frame, a drive motor fixedly connected to the front surface of the fixed frame, the rear output end of the drive motor passing through the fixed frame, a limit roller fixedly connected to the rear output end of the drive motor, a movable plate disposed to the left side of the limit roller, a plurality of scraper needles fixedly connected in a linear array on the bottom surface of the movable plate, a connecting rod fixedly connected to the upper surface of the movable plate, a reciprocating unit disposed to the left side of the connecting rod, the reciprocating unit being used to drive the movable plate to perform reciprocating linear motion in the front-back direction.

[0007] As a further description of the above technical solution:

The rear output end of the reciprocating motor passes through the fixed frame, and a lead screw is fixedly connected to the rear output end of the reciprocating motor. A movable slider is threaded to the outer side of the lead screw, and a limit rod is fixedly connected inside the fixed frame.

[0021] This utility model has the following beneficial effects:

[0022] 1.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2 This utility model provides an embodiment of an anti-entanglement silk cotton carding machine, comprising a housing 1, inside which a carding mechanism 2 is arranged. The carding mechanism 2 includes a feeding mechanism, a licker-in roller, a cylinder, a cover plate, a doffer, a stripper, a dust removal knife, and a waste removal system. The rotation of the licker-in roller and the cylinder decomposes the fiber bundle into single fibers, reducing entanglement. The interaction between the needle cloth of the cylinder and the cover plate causes the fibers to align in parallel, removing residual impurities. The centrifugal force of the licker-in roller, the dust removal knife, and the waste removal system remove impurities from the fibers. The gap between the cover plate and the cylinder... The design separates short fibers and increases the proportion of long fibers. The doffer and stripping device gather the combed fibers into a uniform thin web to prepare for subsequent sliver forming or spinning. During the combing process, different batches or types of fibers are evenly mixed to ensure product consistency. A fixed frame 3 is fixedly connected to the left side of the machine housing 1. A conveyor belt 4 is set inside the fixed frame 3. When the raw material that has been loosened by the opening machine is placed on the conveyor belt 4, it can automatically move the raw material to the feeding mechanism for feeding. The above structures are all existing technologies in the field and will not be described in detail here.

[0032] A drive motor 5 is fixedly connected to the front surface of the fixed frame 3. The rear output end of the drive motor 5 passes through the fixed frame 3. A limit roller 6 is fixedly connected to the rear output end of the drive motor 5. The rear end of the limit roller 6 is rotatably connected to the rear inner wall surface of the fixed frame 3. When the drive motor 5 starts, it can drive the limit roller 6 to rotate. There is a distance between the bottom end of the limit roller 6 and the upper surface of the conveyor belt 4. This distance can be adapted to the optimal feeding thickness of the raw material of the carding machine. When the raw material moves to the right on the conveyor belt 4 and passes through the limit roller 6, the excessively thick raw material will be blocked by the limit roller 6. The raw material that meets the requirements can move directly to the feeding mechanism to the right through the bottom of the limit roller 6.

[0033] Reference Figures 2-4A movable plate 7 is provided on the left side of the limiting roller 6. Several scraper needles 8 are fixedly connected in a straight array on the bottom surface of the movable plate 7. The bottom end of the scraper needles 8 is on the same horizontal plane as the bottom end of the limiting roller 6. The bottom end of the scraper needles 8 is inclined towards the bottom end of the limiting roller 6, which allows the bottom end of the scraper needles 8 to move closer to the bottom of the limiting roller 6, thereby better moving the material blocked by the limiting roller 6. When the movable plate 7 moves, it can drive the scraper needles 8 to move synchronously. When the movable plate 7 drives the scraper needles 8 to move in a straight line in the back and forth direction, it can move the excessively thick material blocked by the limiting roller 6 to the front and back sides, so that the material in the excessively thick position can move to the thinner position, improving the uniformity of feeding and avoiding the phenomenon of entanglement caused by excessively thick material feeding. A connecting rod 9 is fixedly connected to the upper surface of the movable plate 7. When the connecting rod 9 moves, it can drive the movable plate 7 to move synchronously.

[0034] A reciprocating unit 10 is provided on the left side of the connecting rod 9. The reciprocating unit 10 includes a reciprocating motor 101, which is fixedly connected to the front surface of the fixed frame 3. The rear output end of the reciprocating motor 101 passes through the fixed frame 3. A lead screw 102 is fixedly connected to the rear output end of the reciprocating motor 101. The rear end of the lead screw 102 is rotatably connected to the rear inner wall surface of the fixed frame 3. When the reciprocating motor 101 is started, it can drive the lead screw 102 to rotate. A movable slider 103 is threadedly connected to the outer side of the lead screw 102. When the lead screw 102 rotates, it can drive the movable slider 103 to rotate. The slider 103 moves synchronously. The right side surface of the movable slider 103 is fixedly connected to the end of the connecting rod 9 away from the movable plate 7. When the movable slider 103 moves, it can drive the movable plate 7 to move synchronously through the connecting rod 9. The fixed frame 3 is internally fixedly connected to a limiting rod 104. The rear end of the limiting rod 104 passes through the movable slider 103. The limiting rod 104 is inserted into the movable slider 103 and can cooperate with the lead screw 102 to guide and limit the movement of the movable slider 103, so that the movable slider 103 can only move in a straight line in the forward and backward direction.

[0035] When the reciprocating motor 101 starts and drives the lead screw 102 to rotate, it can drive the movable slider 103 to move linearly in the forward and backward direction under the guidance and limitation of the limit rod 104. Since the length of the lead screw 102 is fixed, the moving distance of the movable slider 103 can be controlled by controlling the running time of the reciprocating motor 101. When the movable slider 103 moves to the end of the lead screw 102, the reciprocating motor 101 will drive the lead screw 102 to rotate in the opposite direction, so that the movable slider 103 can move in the opposite direction, thereby realizing the continuous reciprocating linear motion of the movable slider 103. The operation control of the reciprocating motor 101 is a simple PLC control technology in this field, which will not be described in detail here.

[0036] Reference Figures 3-4An L-shaped air pipe 11 is provided above the moving plate 7. An air pump 12 is fixedly connected to the upper surface of the moving slider 103. A connecting pipe 13 is fixedly connected to the right output end of the air pump 12. The bottom of the L-shaped air pipe 11 passes through the moving plate 7, and the bottom of the L-shaped air pipe 11 is inclined towards the bottom end of the limiting roller 6. When airflow passes through the L-shaped air pipe 11, it can blow towards the bottom end of the scraper needle 8. The end of the connecting pipe 13 away from the air pump 12 is fixedly connected to the upper end of the L-shaped air pipe 11. When the air pump 12 is started, it can blow air through the connecting pipe 13 towards the bottom end of the scraper needle 8. Air is pumped inside the L-shaped air tube 11, allowing airflow to be blown from the bottom of the L-shaped air tube 11 to the bottom of the scraper needle 8. There are two L-shaped air tubes 11, located on the front and rear sides of the scraper needle 8 respectively. The number of output ends of the air pump 12 and connecting pipes 13 are matched. When the airflow passes through the bottom of the L-shaped air tube 11, it can blow the material scraped by the scraper needle 8 downward, so that the material can quickly fall when it reaches a thinner section, further improving the sorting and stirring effect of the material.

[0037] Working principle: After the raw material loosened by the opening machine is placed above the conveyor belt 4, the conveyor belt 4 is started to move the raw material to the right. Simultaneously, the drive motor 5 and reciprocating motor 101 are started, causing the limiting roller 6 and the lead screw 102 to rotate synchronously. When the limiting roller 6 rotates, it can screen the raw material moving to the right. Excessively thick material will be blocked by the limiting roller 6, while qualified material can continue to move to the right and enter the combing mechanism 2 for combing processing. When the lead screw 102 rotates, it will be guided by the limiting rod 104. The lower position drives the movable slider 103 to move linearly in the front and back direction, which in turn drives the scraper needle 8 to move synchronously through the connecting rod 9 and the movable plate 7. During this process, the scraper needle 8 will push the excessively thick material blocked by the limiting roller 6 to the front and back sides. At the same time, the air pump 12 is started to blow air to the front and back sides of the scraper needle 8 through the connecting pipe 13 and the L-shaped air pipe 11, so that the material falls quickly when it reaches the thinner part, so that the material can move more evenly to the combing mechanism 2, and avoid the situation where the material is too thick and tangles.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
