Description

Technical Field

[0001] This invention belongs to the field of yarn processing technology, and relates to a yarn production equipment and production method. Background Technology

[0002] In the yarn production field, the drawing frame is one of the key pieces of equipment. Its main function is to combine and draft multiple cotton slivers to improve the structural uniformity and fiber straightness of the slivers, thereby providing stable raw materials for subsequent spinning processes. In the traditional yarn production process, the drawing frame is often used in conjunction with a feed hopper. The feed hopper is used to hold the cotton slivers to meet the continuous production needs of the drawing frame.

[0003] However, existing yarn production equipment has many inconveniences in actual operation. In terms of the use of material hoppers, when the cotton strips in the material hopper are used up, the material hopper needs to be replaced. The traditional replacement method mostly relies on manual operation. Manually moving the material hopper is not only labor-intensive but also inefficient. This problem is even more prominent when the production scale is large and the material hopper needs to be replaced frequently.

[0004] Meanwhile, during the replacement process, the cotton slivers need to be placed on the support frame manually and manually introduced into the drawing frame. Since there are a large number of cotton slivers, they cannot be introduced into the drawing frame at the same time, which reduces the processing efficiency.

[0005] Therefore, we propose a yarn production equipment and method to solve the problems mentioned above. Summary of the Invention

[0006] In view of this, in order to solve the above problems, the present invention provides a yarn production equipment and a production method.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a yarn production device, comprising:

[0008] Drawing frame, used for yarn production;

[0009] A support frame is provided on one side of the drawing frame;

[0010] Multiple support rods are installed on the support frame to guide the cotton strips inside the material bucket;

[0011] Multiple limiting rods are provided on the support rod to limit the movement of the cotton strip;

[0012] The small bucket changing platform is located at the discharge end of the drawing frame and is used to hold the small buckets.

[0013] The first movable frame is movably disposed on one side of the support frame, and a second movable frame is movably connected to one side of the frame.

[0014] The loading and unloading mechanism is respectively set on the first movable frame and the second movable frame. The loading and unloading mechanism includes a driver and a plurality of clamps. The clamps hold the material bucket, and the driver drives the lifting to realize the loading and unloading of the material bucket.

[0015] A fixing component, mounted on the first movable frame, is used to fix one end of the tampon and, in conjunction with the loading and unloading mechanism, to place the tampon into position during the material hopper replacement process.

[0016] As a further improvement to the above technical solution:

[0017] The loading and unloading mechanism further includes: two first sliding blocks that are slidably engaged with the first movable frame; two first fixed rods that are fixedly connected between the two first sliding blocks; and a connecting seat that is fixedly fitted onto the outer wall of the first fixed rod, with the output end of the driver fixedly connected to the connecting seat.

[0018] The clamp includes:

[0019] Two second sliding blocks are slidably mounted on two first fixed rods; a clamping plate is fixedly disposed on the outer end of the second sliding blocks; a guide seat is fixedly installed on one side of the first movable frame, corresponding to the clamp; an extension plate is fixedly disposed on both sides of the guide seat; a guide plate is disposed at one end of the extension plate, abutting against the second sliding blocks; a flange is disposed on the top outer wall of the material bucket, and is used in conjunction with the clamping plate. When the driver lifts, the clamping plate abuts against the bottom of the flange to ensure stable clamping of the material bucket.

[0020] Multiple fixing blocks are fixedly fitted onto the outer walls of two first fixing rods, located between two adjacent second sliding blocks; multiple springs are fitted onto the outer walls of the first fixing rods, with the two ends of each spring contacting the adjacent sides of the fixing blocks and second sliding blocks via spring seats; a guide rod has its bottom end penetrating the top of the guide seat and fixedly connected to the fixing blocks; when the clamp holds or releases the material barrel, the springs act as buffers and resets, ensuring stable clamping force and avoiding excessive squeezing of the material barrel, while the guide rod ensures stable lifting and lowering of the fixing blocks.

[0021] The driver is an electric push rod, which is connected to one side of the first movable frame via a mounting plate. The output end of the electric push rod is fixedly connected to the connecting seat to drive the first fixed rod and the clamp.

[0022] The fixing component includes:

[0023] Multiple mounting bases are fixedly installed on one side of the first movable frame; a second fixing rod is fixedly installed on one side of the mounting base; a clamping rod is fixedly installed at the top of the guide rod, located below the second fixing rod; an extension frame is fixedly installed at the top of the guide rod on one side, located below the second fixing rod on the side; by raising and lowering the fixing block, the clamping rod and the extension frame are driven to move closer to the second fixing rod to fix the cotton strip.

[0024] The first groove is formed at the bottom of the second fixing rod and is adapted to the clamping rod and the extension frame; the second groove is formed on the outer wall of the clamping rod and the extension frame and is used to limit the cotton strip; the cotton strip is clamped between the first groove and the second groove to prevent it from slipping off during the fixing process.

[0025] A sleeve rod is fixedly installed on top of multiple second fixed rods; a sliding rod, L-shaped, is slidably installed inside the sleeve rod, with one end of it fixedly connected to the second movable frame via a connecting rod; when the second movable frame moves, it drives the sliding rod to slide inside the sleeve rod, ensuring the stable movement of the second movable frame.

[0026] Two rotating shafts are rotatably mounted on the top of the sleeve rod; a sprocket is fixedly mounted on the outer wall of the rotating shaft; a chain is driven and connected to the outer wall of the two sprockets; a drive block is fixedly mounted on one side of the chain, and its other end is fixedly connected to the second movable frame; a protective cover is fixedly mounted on the top of the sleeve rod; a motor is fixedly mounted on the top of the protective cover, and the output end of the motor is fixedly connected to the corresponding rotating shaft; a rectangular opening is opened on one side of the protective cover, corresponding to the drive block; the motor drives the rotating shaft to rotate, which in turn drives the drive block to move through the sprocket and chain, thereby driving the second movable frame to move; the protective cover protects the internal transmission components from cotton lint contamination; and the rectangular opening ensures a reliable connection between the drive block and the second movable frame.

[0027] A method for producing yarn, based on the aforementioned yarn production equipment, includes the following steps:

[0028] S1. Place the cotton strip on the support rod of the support frame and between the limit rods, and introduce one end of the cotton strip into the drawing machine;

[0029] S2. Drive the first moving frame to the side of the full material barrel, and drive the second moving frame to move and be misaligned by the motor.

[0030] S3. The electric push rod retracts, clamps the full bucket with the clamp and lifts it up and down, while the fixing component fixes one end of the cotton strip.

[0031] S4. When the material bucket of the support frame is empty, move the first moving frame to the side of the support frame, the electric push rod extends to release the full material bucket, and the fixing component places the cotton strip on the support rod.

[0032] S5. Remove the empty material bucket and repeat the above steps to replace the material bucket.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. The yarn production equipment disclosed in this invention achieves precise positioning of the loading and unloading mechanism in three-dimensional space through the coordinated movement of the first and second moving frames. At the same time, the linkage design of the drive and the clamp ensures that the material bucket maintains horizontal stability during the lifting process. Combined with the flange structure on the top of the material bucket, the loading and unloading efficiency is significantly improved. Before replacement, the material bucket containing cotton strips can be moved to one side of the support frame. When replacement is needed, the empty material bucket can be directly moved out of the support frame, and then the material bucket containing cotton strips can be moved to the bottom of the support frame.

[0035] 2. The yarn production equipment disclosed in this invention, during the lifting and lowering of the fixed block, drives the clamping rod and the extension frame to move through the guide rod, and cooperates with the groove structure at the bottom of the second fixed rod to form a multi-point flexible fixation of the cotton strip, so that the cotton strip can be manually placed before loading and then fixed, so that the cotton strip can be directly positioned during the subsequent replacement of the material bucket without waiting for manual pulling and winding.

[0036] 3. The yarn production equipment disclosed in this invention uses a motor-driven shaft to rotate a sprocket, causing the drive block to run stably along the chain track. This transmission method features accurate transmission ratio and strong load-bearing capacity. Combined with the guiding structure of the sliding rod and sleeve rod, it ensures the smooth movement of the second moving frame. The protective cover not only protects the transmission components from cotton lint contamination, but the rectangular opening design also ensures a reliable connection between the drive block and the second moving frame, extending the equipment's service life.

[0037] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0050] Example 1

[0051] like Figures 1-7 As shown, a yarn production equipment is mainly composed of a drawing frame 1, a material bucket 13, a small bucket material changing platform 5, a first moving frame 6, a second moving frame 7, a loading and unloading mechanism, and fixed components.

[0052] The drawing frame 1 is one of the core components of the entire equipment for yarn production. It adopts a mature textile machinery design and has a stable sliver output capacity. On one side of the drawing frame 1, there is a metal support frame 2. The support frame 2 is made of high-strength steel, such as Q345 steel, and undergoes welding and heat treatment processes to ensure sufficient strength and stability to withstand the weight of subsequently installed components and vibrations during operation. The height of the support frame 2 is set according to the working height and operational requirements of the drawing frame 1.

[0053] Multiple support rods 3 are installed on the support frame 2. These support rods 3 are arranged horizontally, and the spacing is precisely set according to the specifications of the cotton strip and the guiding requirements. The support rods 3 are made of smooth stainless steel tubes with polished surfaces to reduce friction during the conveying process and prevent the cotton strip from pilling or breaking.

[0054] The small bucket changing table 5 is located at the discharge end of the drawing frame 1. When the small bucket is full of finished yarn, it can be easily and automatically removed from the changing table and replaced with an empty bucket, ensuring the continuity of production.

[0055] The first movable frame 6 is movably mounted on one side of the support frame 2. A second movable frame 7 is movably mounted on one side of the first movable frame 6. Both frames have two casters 9 bolted to their bottoms. An AGV trolley is mounted at the bottom of the first movable frame 6, which can automatically control the movement of the frame 6 through programming to achieve automated operation.

[0056] Both the first movable frame 6 and the second movable frame 7 are equipped with loading and unloading mechanisms for loading and unloading the material bucket 13. The loading and unloading mechanism includes a driver 17 and multiple clamps 15. The driver 17 is connected to one side of the first movable frame 6 via a mounting plate 25, and specifically uses an electric push rod 26 as the driving element. The electric push rod 26 is a product from a well-known brand, and its thrust is selected according to the weight of the material bucket 13 and the loading and unloading requirements. The output end of the electric push rod 26 is fixedly connected to a connecting seat 23, which is made of high-strength aluminum alloy and is connected to the output end of the electric push rod 26 and the first fixed rod 19 by bolts.

[0057] There are two first fixing rods 19, which are connected by two first sliding blocks 18. Each first sliding block 18 is slidably fitted onto the first movable frame 6 and contains a linear bearing. The clearance between the first sliding block 18 and the first movable frame 6 is small, ensuring that the first fixing rods 19 can move smoothly on the first movable frame 6 along with the first sliding blocks 18. The first fixing rods 19 are made of solid stainless steel bars, possessing sufficient strength and rigidity.

[0058] The clamp 15 includes two second sliding blocks 21 slidably mounted on two first fixed rods 19. A clamping plate 22 is fixedly mounted on the outer end of each second sliding block 21. The clamping plate 22 is made of flat steel, is arc-shaped, and has a thickness of 5-10 mm. Its surface is treated with an anti-slip coating to increase friction with the flange 14 of the material bucket 13, preventing the material bucket 13 from slipping during loading and unloading. The top outer wall of the material bucket 13 is provided with a flange 14 that cooperates with the clamping plate 22 to prevent it from falling off during lifting.

[0059] A guide seat 32 corresponding to the clamp 15 is fixedly provided on one side of the first movable frame 6. The guide seat 32 is made of metal and is fixed to the first movable frame 6 by bolts. Extension plates 33 are fixed on both sides of the guide seat 32. One end of the extension plate 33 is provided with a guide plate 34 that abuts against the second sliding block 21. The guide plate 34 is made of hard plastic with a smooth surface and can guide the movement of the second sliding block 21 to ensure that the clamp 15 can accurately clamp the material bucket 13. When it is necessary to load or unload the material bucket 13, the electric push rod 26 pushes the connecting seat 23 to move upward, thereby driving the first fixed rod 19 and the second sliding block 21 to move upward. During the upward movement, the guide plate 34 drives the clamping plate 22 to clamp the material bucket 13 and abuts against the bottom of the flange 14 during the lifting process to ensure the stability of the clamping.

[0060] Multiple fixing blocks 20 are fixedly fitted onto the outer walls of the two first fixing rods 19, with the fixing blocks 20 located between two adjacent second sliding blocks 21. The fixing blocks 20 are made of metal and are fixed to the first fixing rods 19 by bolts. Multiple springs 24 are fitted onto the outer walls of the first fixing rods 19, with the two ends of each spring 24 contacting the adjacent sides of the fixing blocks 20 and the second sliding blocks 21 via spring seats. The springs 24 are compression springs. When the clamp 15 holds the material bucket 13, the springs 24 act as a buffer, preventing the clamp 15 from excessively squeezing the material bucket 13 and damaging it. They also ensure the stability of the clamping force of the clamp 15 on the material bucket 13 and automatically drive the clamp 15 away from the material bucket 13 during placement. A guide rod 30 is slidably mounted through the top of the guide seat 32, with the bottom end of the guide rod 30 fixedly connected to the fixing block 20. The guide rod 30 is made of stainless steel to ensure the stability of the fixing block 20 during lifting.

[0061] A fixing component is mounted on the first movable frame 6 to secure one end of the tampon and works in conjunction with the loading and unloading mechanism to place the tampon into position during the replacement of the feed hopper 13. The fixing component includes multiple mounting seats 27 fixed to one side of the first movable frame 6. The mounting seats 27 are made of metal and are bolted to the first movable frame 6. A second fixing rod 28 is fixed to one side of each mounting seat 27. The second fixing rod 28 is made of stainless steel and has a rubber pad at its bottom to increase friction with the tampon.

[0062] Multiple second fixed rods 28 are fixedly mounted on the top of the same sleeve rod 10, which is made of hollow stainless steel tubing. A sliding rod 11, L-shaped, is slidably mounted inside the sleeve rod 10, with one end fixedly connected to the second movable frame 7 via a connecting rod 12. The connecting rod 12 is made of metal and is welded to the sliding rod 11 and the second movable frame 7 to ensure a secure connection. This structure allows the movement of the second movable frame 7 to drive the sliding rod 11 to slide within the sleeve rod 10, ensuring the stability of the movement of the second movable frame 7.

[0063] Example 2

[0064] Reference Figures 1-7 The support rod 3 is equipped with multiple limiting rods 4, which are perpendicular to the support rod 3 and fixed to it with bolts. Their positions can be adjusted according to the width of the cotton strip. The spacing between the limiting rods 4 is 5-10 cm, effectively preventing the cotton strip from shifting or tangling during transport and ensuring stable transport. The ends of the limiting rods 4 are rounded to avoid scratching the cotton strip.

[0065] A clamping rod 29 is fixedly mounted at the top of the guide rod 30, located below the second fixing rod 28. An extension frame 31 is fixedly mounted at the top of the guide rod 30 on one side, located below the second fixing rod 28 on the side. A first groove 35 is formed at the bottom of the second fixing rod 28, which is adapted to the clamping rod 29 and the extension frame 31. A second groove 36 is formed on the outer wall of the clamping rod 29 and the extension frame 31 to limit the cotton strip. The first groove 35 and the second groove 36 are semi-circular in shape, which can effectively prevent the cotton strip from slipping off during the fixing process.

[0066] When the fixing block 20 rises, it drives the clamping rod 29 and the extension frame 31 to move closer to the second fixing rod 28, clamping the cotton strip between the first groove 35 and the second groove 36, thereby fixing the cotton strip.

[0067] The top of the sleeve rod 10 is equipped with two rotating shafts 37. The shafts 37 are made of high-strength steel and have undergone quenching treatment to improve their hardness and wear resistance. A sprocket 38 is fixedly fitted onto the outer wall of each shaft 37. The outer walls of the two sprockets 38 are connected by the same chain 39. A drive block 40 is fixedly mounted on one side of the chain 39, and the other end of the drive block 40 is fixedly connected to the second movable frame 7. A protective cover 41 is fixedly mounted on the top of the sleeve rod 10. The protective cover 41 is made of metal and has a painted surface, serving to prevent rust and protect internal components. A motor 16 is fixedly mounted on the top of the protective cover 41. The motor 16 is a common three-phase asynchronous motor. The output end of the motor 16 is fixedly connected to the corresponding rotating shaft 37. A rectangular opening 42 corresponding to the drive block 40 is provided on one side of the protective cover 41. The size of the rectangular opening 42 is designed according to the size of the drive block 40 to ensure that the drive block 40 can move freely. When the second moving frame 7 needs to be moved, the motor 16 is started to drive the rotating shaft 37 to rotate. During the rotation, the chain 39 can be moved through the sprocket 38, and the drive block 40 is moved. The movement of the drive block 40 will drive the second moving frame 7 to move along the length direction of the first moving frame 6, so that the material bucket 13 in the first moving frame 6 corresponds to the support frame 2.

[0068] Working principle:

[0069] When in use, place the cotton strips in the material bucket 13 on the support rod 3 and between the two limit rods 4. At the same time, place one end of multiple cotton strips in the drawing machine 1 for drawing, and then drop them into the small bucket on the small bucket changing table 5.

[0070] At the same time, the AGV trolley 8 is started to drive the first moving frame 6 to move to the side of the material bucket 13 filled with cotton strips. The motor 16 is started to drive one of the rotating shafts 37 to rotate. During the rotation of the rotating shaft 37, the drive block 40 can be driven to move through the sprocket 38 and the chain 39. Since the drive block 40 is fixed on the second moving frame 7, the movement of the drive block 40 can drive the second moving frame 7 to move, and cause the sliding rod 11 to move within the sleeve rod 10 until the second moving frame 7 and the first moving frame 6 are misaligned.

[0071] The AGV trolley 8 is started to drive the first moving frame 6 to approach the material bucket 13 until the material bucket 13 is located between the corresponding two clamping plates 22. One end of the cotton strip in the material bucket 13 is placed on multiple clamping rods 29 and extension frame 31 in sequence. The electric push rod 26 is started to retract. During the retraction of the electric push rod 26, it can drive the two first fixed rods 19 to move upward through the connecting seat 23. The upward movement of the first fixed rods 19 can drive multiple sets of clamping plates 22 to move upward. When the clamping plates 22 contact the guide plate 34, they can overcome the force of the spring 24 and use the inclined surface of the guide plate 34 to drive the clamping plates 22 to move inward, so that the two clamping plates 22 clamp the material bucket 13. At the same time, the clamping plates 22 abut against the bottom of the flange 14 on the material bucket 13 until the material bucket 13 is lifted off the ground.

[0072] During the upward movement of the first fixing rod 19, the guide rod 30 can be driven to move upward through the fixing block 20. The upward movement of the guide rod 30 can drive the clamping rod 29 and the extension frame 31 to move upward, which can cooperate with the second fixing rod 28 above to clamp and fix the cotton strip.

[0073] The starter motor 16 rotates in the reverse direction, driving the second movable frame 7 to move to one side of the first movable frame 6;

[0074] When it is necessary to replace the material bucket 13 under the support frame 2, start the AGV trolley 8 to drive the first moving frame 6 and the second moving frame 7 to move to one side of the support frame 2, so that the material bucket 13 is located in the multiple clamps 15 on the second moving frame 7, start the electric push rod 26 on the second moving frame 7 to retract, and fix and lift the material bucket 13.

[0075] The start motor 16 drives the second moving frame 7 to move to one side, so that the first moving frame 6 corresponds to the support frame 2. The AGV trolley 8 is started to drive the first moving frame 6 to move into the support frame 2. At this time, the clamping rod 29 is located above the top of the limit rod 4. The electric push rod 26 on the first moving frame 6 is started to extend. During the extension process, it can push the first fixed rod 19 to move downward, and can drive the clamping rod 29 and the extension frame 31 to move downward, placing the cotton strip on the support rod 3 and between the two adjacent limit rods 4.

[0076] Continue to activate the electric push rod 26 to extend, and place the material bucket 13 filled with cotton strips in the first moving frame 6 on the ground. At this time, the second sliding block 21 moves to the bottom of the guide plate 34 and moves outward with the force of the spring 24, so that it is away from the material bucket 13.

[0077] Start the AGV trolley 8 to drive the first moving frame 6 to move outward, then start the motor 16 to drive the second moving frame 7 to reset and move. Then use the above method to place the empty material bucket 13 in the designated position, and load the material bucket 13 filled with cotton strips through the first moving frame 6.

[0078] However, as is well known to those skilled in the art, the working principles and wiring methods of the drawing frame 1, AGV trolley 8, motor 16 and electric push rod 26 are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
