Description

Technical Field

[0001] The present invention belongs to the field of spinning machinery equipment, and particularly relates to a multi-motor servo-driven high-speed sliver lap machine. Background Art

[0002] In the current cotton spinning process, the main types of cotton spinning comber sliver lap machines are the roller winding type and the belt winding type. Among them, the roller winding type sliver lap machine has a simple structure and low working costs, but its maximum production speed is only 120 - 130 meters per minute, and the output does not exceed 350 kilograms per hour; the production speed of the belt winding type sliver lap machine can reach 230 meters per minute, and the output is 600 kilograms per hour, but its machine structure is complex, the production cost is very high, and the requirements for machine production maintenance are also very high.

[0003] Currently, most manufacturers still use the roller winding type sliver lap machine by extending working hours to meet the output requirements and reduce production costs, but this is ultimately not a long-term solution, and there are still many inconveniences in the use of the roller winding type sliver lap machine. For example: this type of machine uses a single ordinary motor to provide power for the front lap roller, rear lap roller, and pressure roller in the machine through a gearbox. On the premise of causing a high load on the single ordinary motor, the production speed and output of the machine have reached their limits, and this is far from enough in modern production; in addition, this type of machine relies on a large gearbox to provide transmission for the front lap roller, rear lap roller, and pressure roller in the machine at the same time. While the accuracy requirements for the gearbox are relatively strict, when changing the cotton yarn material wound by this sliver lap machine, the module, number of teeth, etc. of the gears in its gearbox need to be adjusted as required, which reduces the practicability of this roller winding type sliver lap machine, and the adjustment process of the gearbox greatly increases the production cost. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a multi-motor servo-driven high-speed sliver lap machine, which is based on the original roller winding type sliver lap machine for transformation with a small increase in cost, aiming to overcome the defects of the original roller winding type sliver lap machine, such as low production speed and output, low practicability for winding different cotton yarn materials, and high cost for adjusting the gearbox.

[0005] In order to achieve the above invention purpose, the present invention adopts the following technical solutions:

[0024] Preferably, the control device includes a display screen and a controller. Control signals are sent to the controller through the display screen, and then the movements of the first servo motor, the second servo motor, and the third servo motor are controlled.

[0025] The beneficial effects of the present invention are as follows:

[0033] 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.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Due to the improvement of the requirements for the output and quality of the cotton spinning process in modern industry, most manufacturers still use the roller winding type sliver lap machine by extending working hours to meet the output requirements and reduce production costs. However, this type of machine uses a single ordinary motor to provide power for the front lap roller, rear lap roller, and pressure roller in the machine. On the premise of causing a high load on the single ordinary motor, the production speed and output of the machine have reached the limit, which is far from enough in modern production.

[0036] Therefore, based on the original model, the inventor of the present invention replaces the single ordinary motor in the original model with three independent servo motors, and at the same time supplements a new control device and three sets of transmission mechanisms to provide power for the first pressure roller, front lap roller, and rear lap roller, effectively solving the problem of low production speed and output of the original model due to the influence of the rated driving power of the original model and the structure of the transmission mechanism itself.

[0037] Next, the technical solutions of the present invention will be described in detail in conjunction with the drawings.

[0038] A multi-motor servo-driven high-speed sliver lap machine according to the present invention includes: a frame 1, a pressure roller drafting mechanism 2, a coil holding mechanism 3, a driving mechanism 4, a transmission mechanism 5, and a control mechanism 6. In the present invention, the cotton web after drawing the sliver is input into the pressure roller drafting mechanism 2, pressed into a cotton sheet, and then input into the coil holding mechanism 3. By using the linkage between the front coil holding roller 301, the rear coil holding roller 302, and the bobbin 303, and supplemented by three independent driving systems mainly composed of the driving mechanism 4, three independent transmission systems in the transmission mechanism 5, and the cooperation of the control mechanism 6, the cotton sheet is wound around the bobbin 303, greatly improving the production speed and output of the present invention.

[0039] In the present invention, as Figures 1-3 shown, the frame 1 is used to support the entire sliver lap machine. The frame 1 includes at least two wallboards, the two wallboards are arranged in parallel, and an installation area is formed between the two wallboards.

[0040] In this technical solution, the present invention is modified based on the original roller winding type sliver lap machine, that is, installed and arranged on the original frame 1. This solution saves production costs and improves the utilization rate of the original model.

[0041] In the present invention, as Figures 1-3 shown, the pressure roller drafting mechanism 2 is located in the installation area, and the pressure roller drafting mechanism 2 is arranged at the input end of the sliver lap machine. The pressure roller drafting mechanism 2 includes a first pressure roller 201, a second pressure roller 202, a third pressure roller 203, and a fourth pressure roller 204. The cotton web passes through the fourth pressure roller 204, the third pressure roller 203, the second pressure roller 202, and the first pressure roller 201 in a meandering manner, is successively pressed to form a cotton sheet, and is drafted and fed into the coil holding mechanism 3.

[0042] Among them, in the pressure roller drafting mechanism 2, the fourth pressure roller 204, the third pressure roller 203, the second pressure roller 202, and the first pressure roller 201 are arranged in sequence along the circumference of the front coil holding roller 301 from the input end of the cotton web to the output end of the cotton sheet.

[0043] In this embodiment, the cotton web passes through the fourth pressure roller 204, the third pressure roller 203, the second pressure roller 202, and the first pressure roller 201 in a meandering manner for successive pressing, so that the output cotton sheet is thinner and the rebound effect is reduced.

[0044] In the present invention, as Figures 1-3As shown, the roll supporting mechanism 3 is disposed below the roller drafting mechanism 2. The roll supporting mechanism 3 includes a front roll supporting roller 301, a rear roll supporting roller 302, and a bobbin 303. The front roll supporting roller 301, the rear roll supporting roller 302, and the bobbin 303 are arranged in a “pin” shape. Among them, the bobbin 303 is disposed on a pressing mechanism 304. The bobbin 303 is in contact with both the front roll supporting roller 301 and the rear roll supporting roller 302, and is located above the front roll supporting roller 301 and the rear roll supporting roller 302. During operation, the pressing mechanism 304 drives the bobbin 303 to provide a downward pressure along the same tangent direction of the front roll supporting roller 301 and the rear roll supporting roller 302, thereby completing the winding of the cotton sheet of the sliver lap machine.

[0045] Among them, as Figure 4 shown, the pressing mechanism 304 includes a pressing arm 305, a conversion arm 306, and a pressing cylinder 307. The pressing arm 305 is movably installed on both sides of the frame 1 along the same tangent direction of the front roll supporting roller 301 and the rear roll supporting roller 302. A bobbin hole 308 is provided on the pressing arm 305. The pressing arm 305 is sleeved with the bobbin 303 through the bobbin hole 308. One end of the pressing arm 305 is connected to one end of the conversion arm 306; the center of the conversion arm 306 is rotatably connected to the bottom of the installation area through a rotating shaft, and the other end of the conversion arm 306 is connected to the output end of the pressing cylinder 307;

[0046] The cylinder body of the pressing cylinder 307 is horizontally disposed at the bottom of the installation area. When the pressing cylinder 307 operates, the pressing cylinder 307 provides a thrust to the conversion arm 306. Through the rotation of the conversion arm 306, the direction of this thrust is changed, and finally this thrust is converted into a pressure applied to both the front roll supporting roller 301 and the rear roll supporting roller 302 along the same tangent direction of the front roll supporting roller 301 and the rear roll supporting roller 302. Among them, the converted pressure is transmitted from the pressing arm 305 to the bobbin 303, and the front roll supporting roller 301 and the rear roll supporting roller 302 are simultaneously pressed through the bobbin 303.

[0047] In this embodiment, grooves 309 are also uniformly provided on the circumferential outer wall of the front roll supporting roller 301. By means of the grooves 309, the friction between the front roll supporting roller 301 and the cotton sheet is increased. Supplementary to the pressure of the pressing mechanism 304 on the bobbin 303, after the cotton sheet is pulled, the cotton sheet is stably wound on the surface of the bobbin 303. Among them, the output directions of the front roll supporting roller 301 and the rear roll supporting roller 302 are the same.

[0048] In the present invention, as Figures 1-3As shown, the driving mechanism 4 is arranged on both sides of the frame 1.

[0052] The first pressure roller transmission mechanism 502 includes a first transmission shaft 513. One end of the first transmission shaft 513 is connected to the output end of the first servo motor 401. A first driving belt gear 514 is arranged at the other end of the first transmission shaft 513. The first driving belt gear 514 is connected to a first driven belt gear 516 through a first belt 515. The first driven belt gear 516 is arranged at the input end of the first pressure roller 201. The power of the first servo motor 401 is transmitted to the entire pressure roller drafting mechanism 2 through the first pressure roller transmission mechanism 502;

[0053] The front take-up roller drive mechanism 503 includes a second transmission shaft. One end of the second transmission shaft is connected to the output end of the second servo motor 402. The other end of the second transmission shaft is provided with a second driving belt gear. The second driving belt gear is connected to a second driven belt gear 520 through a second belt 519. The second driven belt gear 520 is connected to a front take-up roller shaft 521. The power of the second servo motor 402 is transmitted to the front take-up roller 301 through the front take-up roller drive mechanism 503;

[0054] The rear take-up roller drive mechanism 504 includes a third transmission shaft. One end of the third transmission shaft is connected to the output end of the third servo motor 403.

The power of the third servo motor 403 is transmitted to the rear take-up roller 302 through the rear take-up roller drive mechanism 504.

[0055] In addition, as Figures 1-2 shown, the drive mechanism 5 further includes a small wall panel 527, a first drive support frame 529 and a second drive support frame 530. The small wall panel 527 is installed on one side of the frame 1 through four feet 528. The small wall panel 527 is provided with a first drive installation hole and a second drive installation hole. The output end of the first transmission shaft 513 passes through the first drive installation hole. The output end of the second transmission shaft 517 passes through the second drive installation hole. The second servo motor 402 is also provided on the small wall panel 527; the output end of the first servo motor 401 and one end of the first transmission shaft 513 connected to the output end of the first servo motor 401 are both arranged on the first drive support frame 529; the output end of the third servo motor 403, the third transmission shaft 522 and the third driven belt gear 525 are all arranged on the second drive support frame 530; the small wall panel 527, the first drive support frame 529 and the second drive support frame 530 provide a structural basis for the stable transmission of power of the drive mechanism 5.

[0056] Based on the above embodiments, what is more important is that: on the basis of the original roller winding type sliver lap machine, the present invention uses three independent first servo motors 401, second servo motors 402 and third servo motors 403 to replace the single ordinary motor in the original model, and at the same time correspondingly sets three independent first pressure roller drive mechanisms 502, front take-up roller drive mechanisms 503 and rear take-up roller drive mechanisms 504 to replace the gearbox in the original model, and provides power for the first pressure roller 201, the front take-up roller 301 and the rear take-up roller 302 respectively. The specific transmission method is as Figure 5As shown, the production speed and output of the present invention in the drawing-in and lap-forming process are greatly improved; in addition, replacing the gearbox with the new transmission mechanism 5 simplifies the original complex transmission system and reduces the failure rate of the transmission mechanism 5 in the present invention. Compared with the disadvantages of the toothed chain in the original model, such as slow speed and high noise, the first belt 515, the second belt 519, and the third belt 524 used in the present invention are rubber toothed belts, which are lighter in texture and faster in speed; furthermore, the horizontal and vertical sides of the four supports 528 for fixing the small wallboard 527 have relatively high process standards, ensuring the stable transmission of the power of the transmission mechanism and improving the stability of the operation of the entire drawing-in and lap-forming machine.

[0057] In the present invention, as Figure 2 shown, the control device 6 is provided on the frame 1 and includes a display screen 601 and a controller 602. Control signals are sent to the controller 602 through the display screen 601, and then the movements of the first servo motor 401, the second servo motor 402, and the third servo motor 403 are controlled.

[0058] Based on the above embodiments, more importantly: the present invention uses the control device 6 to uniformly regulate and monitor the working states of the first servo motor 401, the second servo motor 402, and the third servo motor 403 to ensure simultaneous operation and simultaneous stop; ensure that the running speeds of the first pressing roller 201, the front lap-forming roller 301, and the rear lap-forming roller 302 are the same. Here, the same speed specifically refers to the same numerical value of the running linear speed; it can also be regulated according to the different lap-forming requirements of different cotton yarn materials, increasing the practicability of the present invention.

[0059] Specifically, when the present invention is working, the first servo motor 401, the second servo motor 402, and the third servo motor 403 simultaneously drive the first pressing roller 201, the front lap-forming roller 301, and the rear lap-forming roller 302 to perform movements with the same numerical value of the running linear speed; the roller drafting mechanism 2 gradually presses the cotton web that winds around the four rollers into a cotton sheet, and then through the cooperation of the front lap-forming roller 301, the rear lap-forming roller 302, and the bobbin 303, the cotton sheet is wound around the bobbin 303. During this period, the pressing mechanism 304 of the bobbin 303 provides pressure that is simultaneously applied to the front lap-forming roller 301 and the rear lap-forming roller 302; when the present invention lap-forms different cotton yarn materials or has different lap-forming requirements, the running states of the first pressing roller 201, the front lap-forming roller 301, and the rear lap-forming roller 302 are regulated through the display screen 601 of the control device 6 to meet different requirements.

[0060] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
