Description

Technical Field

[0001] The present invention relates to the field of drawing frames, in particular to a drawing frame for chemical fiber blended products. Background Art

[0002] Textile machinery is a general term for the various mechanical devices required to process natural or chemical fibers into textiles. The processes required to process different fibers, such as cotton, linen, silk, and wool, into textiles vary, necessitating a wide variety of machinery. This primarily includes spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber spinning equipment, silk reeling equipment, and non-woven fabric equipment. Spinning equipment is categorized into two types, depending on the raw materials being processed: short fiber processing and long fiber processing. The processing steps for these two types of fibers differ, and the equipment cannot be interchangeable. For long fiber processing, the following processes, in their order of importance within the process flow, include opening and cleaning machinery, carding machines, and drawing frames.

[0003] The function of the draw frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments while reducing weight unevenness. This straightens and parallelizes the fibers in the sliver, reduces hooks, ensures that the fineness meets the specified requirements, and evenly blends raw materials of different types or qualities to achieve the specified blend ratio. Draw frames are divided into two categories based on the drafting mechanism: roller drafting draw frames and gilling draw frames.

[0004] However, the existing drawing machines mostly use a one-to-one single roller body, and after the chemical fiber blended product is pulled and squeezed by the roller body, in order not to affect the arrangement structure of the internal lines of the chemical fiber blended product, the drawing process of the chemical fiber blended product is manually intervened by the operator, that is, the chemical fiber blended product after the initial extrusion is manually pulled into the next processing station. In this process, traditional belt transmission and chain transmission are not applicable. First, the traditional leather conveyor belt cannot be equipped with a traction component, that is, it is impossible to draw the chemical fiber blended product after the initial extrusion; and the chain transmission is blocked by chemical fiber debris between the chain links after a long period of work due to the presence of chemical fiber debris, causing the device to fail to operate normally, and the chain can only change the angle parallel to the sprocket end face, and cannot change the angle in multiple planes. Therefore, in order to improve production efficiency and reduce manual intervention of operators, it is necessary to design a chemical fiber blended product drawing machine that can evenly pull chemical fiber blended products and does not require manual intervention in this process.

[0036] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] refer to Figures 1 to 9 , a drawing frame for chemical fiber blended products, comprising:

[0038] Four supporting bases 1 are arranged in a vertical state;

[0039] The carrying platform 2 is fixedly arranged on the upper ends of the four supporting bases 1;

[0040] Two baffles 5 are arranged in a vertical state and are respectively connected to the two long sides of the carrying platform 2;

[0041] The transmission mechanism 6 is connected to the two baffles 5, and the transmission mechanism 6 can perform the initial extrusion and traction for the chemical fiber blended product to be processed;

[0042] The steering and pulling assembly 15 includes two steering and pulling mechanisms 16 symmetrically arranged about the center line of the short side of the carrying platform 2. The steering and pulling mechanisms 16 can steer and pull the chemical fiber blended product after the initial extrusion;

[0043] Two drawing mechanisms 32 are symmetrically arranged about the center line of the short side of the carrying platform 2. The two drawing mechanisms 32 can perform secondary extrusion on the chemical fiber blended product pulled by the steering and pulling mechanism 16;

[0044] The guiding mechanism 36 is connected to the two steering and pulling mechanisms 16. The guiding mechanism 36 can guide the chemical fiber blended product after two extrusion and drawing processes to the next processing device.

[0045] The transmission mechanism 6 includes several traction roller shafts 7, several traction roller cores 8, several transmission wheels 9 and several belts 10, wherein the several traction roller cores 8 are arranged at equal intervals along the long side direction of the carrying platform 2, and every two adjacent traction roller cores 8 are staggered. The two ends of the traction roller core 8 pass through the two baffles 5 and are rollingly connected with the two baffles 5. The traction roller shaft 7 is coaxially fixedly sleeved on the outside of the traction roller core 8, and the two transmission wheels 9 are coaxially fixedly sleeved on the two ends of the traction roller core 8. The two ends of the belt 10 are rollingly sleeved with the two adjacent transmission wheels 9. When the device is running, the transmission wheel 9 rotates to drive the traction roller core 8 to rotate. The traction roller shaft 7 is fixedly sleeved on the outside of the traction roller core 8. The rotation of the traction roller core 8 drives the traction roller shaft 7 to rotate. The two ends of the belt 10 are rolled and sleeved with the two adjacent transmission wheels 9. When one transmission wheel 9 rotates, this transmission wheel 9 will drive the adjacent transmission wheel 9 to rotate. When the traction roller shaft 7 rotates, the chemical fiber blended product will be pulled by the two adjacent traction roller shafts 7. At this time, the chemical fiber blended product will be initially extruded and shaped by the traction roller shaft 7, and then the chemical fiber blended product that has undergone preliminary processing will be pulled for further processing.

[0046] The transmission mechanism 6 also includes a transmission motor 11, a driving wheel 12, a motor wheel 13 and a power roller shaft 14. The transmission motor 11 is arranged in a horizontal state through the motor frame. The motor wheel 13 is coaxially fixedly sleeved on the outside of the output end of the transmission motor 11. The transmission wheel 9 is transmitted by the motor wheel 13 through the belt 10. The driving wheel 12 is located above the motor wheel 13. The driving wheel 12 is transmitted by the motor wheel 13 through the belt 10. One end of the power roller shaft 14 passes through the baffle 5 and is coaxially fixedly inserted with the driving wheel 12, and the other end passes through the baffle 5 and is rollingly connected to the baffle 5. When the device is running: the transmission motor 11 is working, and the motor wheel 13 is fixedly sleeved on the outside of the motor output end. When the motor wheel 13 starts to rotate, since the motor wheel 13 is simultaneously transmitted with the transmission wheel 9 and the driving wheel 12 through two belts 10, the rotation of the motor wheel 13 will drive the transmission wheel 9 to rotate, and the rotation of the transmission motor 11 will also drive the driving wheel 12 to rotate. The driving wheel 12 is fixedly sleeved with the power roller shaft 14, and the rotation of the driving wheel 12 will drive the power roller shaft 14 to rotate.

[0047] The carrying platform 2 is formed with two first avoidance grooves 3, and the two first avoidance grooves 3 are symmetrically arranged about the center line of the short side of the carrying platform 2. The steering and pulling assembly 15 includes two groups of steering and pulling mechanisms 16, and the two groups of steering and pulling mechanisms 16 are arranged in the two first avoidance grooves 3. Each steering and pulling mechanism 16 includes a transmission belt 17, a first transmission gear 22, a transmission baffle 23, a universal transmission chain 27 and a second transmission gear 31. The first transmission gear 22 is coaxially fixed on the outside of the power roller shaft 14, and the transmission belt 17 is meshed with the first transmission gear 22 for transmission. The universal transmission chain 27 is located inside the transmission belt 17, and the universal transmission chain 27 provides support for the transmission belt 17. The two transmission baffles 23 are vertically arranged on both sides of the transmission belt 17. At the same time, the two transmission baffles 23 are rollingly connected to the power roller shaft 14 near one end of the first transmission gear 22, and the second transmission gear 31 is arranged at the end of the transmission belt 17 away from the first transmission gear 22. When the device is running: the first transmission gear 22 is fixedly sleeved on the outside of the power roller shaft 14, and the rotation of the power roller shaft 14 will drive the first transmission gear 22 to rotate, and the transmission belt 17 is meshed with the first transmission gear 22 for transmission, and the rotation of the first transmission gear 22 will drive the transmission belt 17 to rotate, and one end of the transmission belt 17 is meshed with the first transmission gear 22 for transmission, and the other end is meshed with the second transmission gear 31 for transmission, and the rotation of the transmission belt 17 will drive the second transmission gear 31 to rotate, and two transmission baffles 23 are vertically arranged on both sides of the transmission belt 17. The two transmission baffles 23 can prevent the debris of chemical fiber blended products from flying into the transmission belt 17 during the drawing process. After a long time, the debris of chemical fiber blended products gradually accumulates and causes the device to run smoothly. The transmission belt 17 is made of soft rubber material and has certain ductility and plasticity. However, in the actual transmission process, if only the transmission belt 17 is relied upon for transmission, the transmission belt 17 is too soft and cannot achieve the traction effect on the chemical fiber blended products. Therefore, the transmission belt 17 needs to be provided with auxiliary parts to pull the chemical fiber blended products. Therefore, a skeleton needs to be provided inside the transmission belt 17. This skeleton can fix the auxiliary parts for traction without affecting the plasticity of the transmission belt 17. The skeleton of the transmission belt 17 in this device adopts a universal transmission chain 27. The existence of the universal transmission chain 27 can provide support inside the transmission belt 17 without affecting the change of any angle of the transmission belt 17 during the transmission process.

[0048] The steering and pulling mechanism 16 also includes a plurality of hooks 24, each of which is formed with a tip 25 and a connecting end 26. The universal transmission chain 27 includes a plurality of universal ball heads 28, a plurality of connecting short rods 29 and a plurality of universal ball sleeves 30. One end of the connecting short rod 29 is fixedly plugged into the universal ball head 28, and the universal ball sleeve 30 is fixedly sleeved on the other end of the connecting short rod 29, and the universal ball sleeve 30 is also connected to the adjacent universal ball head 28. The tip 25 of the hook 24 extends out of the transmission belt 17, and the connecting end 26 of the hook 24 is fixedly sleeved on the outside of the connecting short rod 29. When the device is in operation, the connecting end 26 of the hook 24 is fixedly sleeved on the outside of the connecting short rod 29. The tip 25 of the hook 24 passes through the transmission belt 17 and extends outward. When the transmission belt 17 rotates, the universal transmission chain 27 set inside the transmission belt 17 will rotate accordingly. The universal ball sleeve 30 is fixedly sleeved on one end of the connecting short rod 29, and the universal ball head 28 is fixedly sleeved on the other end of the connecting short rod 29. When the chemical fiber blended product needs to change its angle during traction, the universal ball sleeve 30 will deflect with the universal ball head 28. The accumulated local deflection will cause the overall movement trajectory of the universal transmission chain 27 to deflect, and the hook 24 can pull the chemical fiber blended product after primary processing. This allows the chemical fiber blended product after primary processing to undergo the next drawing and extrusion without human intervention.

[0049] The transmission belt 17 includes a transmission toothed belt 21, a transmission belt 18 and two connecting baffles 20. One end of the transmission toothed belt 21 is engaged with the first transmission gear 22, and the other end is engaged with the second transmission gear 31. The transmission belt 18 includes a plurality of transmission belt pieces 19 and two connecting baffles 20. The two connecting baffles 20 are fixedly arranged on both sides of the transmission toothed belt 21. The two connecting baffles 20 are sewn together with a plurality of connecting short rods 29. At the same time, the two connecting baffles 20 are sewn together with the transmission toothed belt 21, and a plurality of transmission belt pieces 19 are sewn together with the two connecting baffles 20. A plurality of transmission belt pieces 19 are sewn together in pairs. At the same time, a plurality of transmission belt pieces 19 are sewn together with a plurality of connecting short rods 29. When the device is in operation: one end of the transmission toothed belt 21 is meshed with the first transmission gear 22, and the other end is meshed with the second transmission gear 31. Then, when the first transmission gear 22 rotates, the transmission toothed belt 21 can rotate accordingly. At the same time, the rotation of the transmission toothed belt 21 can drive the rotation of the second transmission gear 31. The two connecting baffles 20 are used to connect the transmission toothed belt 21 with the plurality of transmission belt pieces 19. Due to the limitations of the processing technology, the two connecting baffles 20 and the plurality of transmission belt pieces 19 need to be sewn together by the processing personnel during processing, and the connecting short rod 29 needs to be sewn together during sewing, so that the connecting short rod 29 is fixedly connected to the transmission belt piece 19 and the transmission toothed belt 21, so that the transmission toothed belt 21 can drive the connecting short rod 29 to move when it moves. It should be noted that the material of the transmission belt piece 19, the connecting baffle 20 and the transmission toothed belt 21 is soft rubber material. This material has strong plasticity and soft texture, which is convenient for processing personnel to sew.

[0050] The drawing mechanism 32 includes a drawing extrusion wheel 33 and a power motor 35. The drawing extrusion wheel 33 is located beside the conveyor belt 18. The drawing extrusion wheel 33 is formed with an extrusion portion 34. The power motor 35 is hoisted at the lower end of the carrying platform 2. The output shaft of the power motor 35 extends upward and is fixedly connected to the drawing extrusion wheel 33 coaxially. When the device is in operation: the power motor 35 is running, and the two drawing extrusion wheels 33 are respectively fixedly connected coaxially with the output shaft of the power motor 35. The operation of the power motor 35 drives the two drawing extrusion wheels 33 to rotate, and the two drawing extrusion wheels 33 turn in opposite directions. The chemical fiber blended product pulled by the crochet hook 24 can be further drawn and extruded by the extrusion portion 34. This extrusion is the secondary drawing extrusion. The chemical fiber blended product after extrusion can be woven and drawn or parallel drawn according to production needs.

[0051] The carrying platform 2 is also formed with a second avoidance groove 4, which is located in the middle of the two drawing extrusion wheels 33. The guiding mechanism 36 includes a traction gear 37, a traction belt 38, an auxiliary gear 39, a limit shaft 40, two limit frames 41, a plurality of positioning shafts 42 and a plurality of positioning rollers 43. The traction gear 37 is fixedly sleeved on the middle part of the power roller shaft 14, and the auxiliary gear 39 is located between the two second transmission gears 31. At the same time, the auxiliary gear 39 also passes through the second avoidance groove 4, and one end of the traction belt 38 is engaged with the traction gear 37, and the other end passes through the two After the strip extrusion wheels 33 are drawn, they are meshed with the auxiliary gear 39. The limiting shaft 40 passes through the two second transmission gears 31 in a horizontal state. At the same time, the limiting shaft 40 is rolled and sleeved on the middle part of the limiting shaft 40. The two limiting frames 41 are fixedly set at both ends of the limiting shaft 40. The two ends of the limiting shaft 40 pass through the transmission block 23 and are rolled in connection with the two limiting frames 41. Several positioning shafts 42 are fixedly inserted in the upper end of the carrying platform 2 in a vertical state. The positioning roller 43 is coaxially rolled with the positioning shaft 42, and the outer edge of the positioning roller 43 slides with the transmission block 23. When the device is running: Since the second transmission gear 31 and the first transmission gear 22 rely on the transmission toothed belt 21 for transmission, but the transmission toothed belt 21 changes direction many times during the transmission process, its transmission force cannot support the normal rotation of the second transmission gear 31, so the auxiliary gear 39 is used to supplement the power for the second transmission gear 31, one end of the traction belt 38 is engaged with the auxiliary gear 39, and the other end is engaged with the traction gear 37, then the traction gear 37 is fixedly sleeved with the power roller shaft 14, and the rotation of the power roller shaft 14 will drive the rotation of the traction gear 37, and the rotation of the traction gear 37 The auxiliary gear 39 will be driven to rotate through the traction belt 38. The rotation of the auxiliary gear 39 supplements the power of the second transmission gear 31. The second avoidance groove 4 provides avoidance space for the auxiliary gear 39 to prevent the auxiliary gear 39 from colliding with the support platform during rotation. Several positioning shafts 42 are fixedly inserted in a vertical state on the upper end of the carrying platform 2. The positioning roller 43 is coaxially connected to the positioning shaft 42 in a rolling manner. The positioning shaft 42 is used to change the moving trajectory of the conveyor belt 21. At the same time, the positioning shaft 42 slides with the transmission baffle 23 to assist in limiting the pulled chemical fiber blended products.

[0052] The working principle of this device is: when the device is running: the transmission motor 11 is working, and the motor wheel 13 is fixedly sleeved on the outside of the motor output end. When the motor wheel 13 starts to rotate, since the motor wheel 13 is simultaneously transmitted with the transmission wheel 9 and the driving wheel 12 through two belts 10, the rotation of the motor wheel 13 will drive the transmission wheel 9 to rotate, and the rotation of the transmission wheel 9 drives the traction roller core 8 to rotate. The traction roller shaft 7 is fixedly sleeved on the outside of the traction roller core 8, and the rotation of the traction roller core 8 drives the traction roller shaft 7 to rotate. The two ends of the belt 10 are rolled and sleeved with the two adjacent transmission wheels 9. When one transmission wheel 9 rotates, this transmission wheel 9 will drive the adjacent transmission wheel 9 to rotate. When the traction roller shaft 7 rotates, the chemical fiber blended product will be pulled by the two adjacent traction roller shafts 7. At this time, the chemical fiber blended product will be initially extruded and shaped by the traction roller shaft 7, and then the chemical fiber blended product that has undergone preliminary processing will be pulled for further processing. And the rotation of the transmission motor 11 will also drive the driving wheel 12 to rotate. The driving wheel 12 is fixedly sleeved with the power roller shaft 14. The rotation of the driving wheel 12 will drive the power roller shaft 14 to rotate. The first transmission gear 22 is fixedly sleeved on the outside of the power roller shaft 14. The rotation of the power roller shaft 14 will drive the first transmission gear 22 to rotate. The transmission belt 17 is meshed with the first transmission gear 22 for transmission. The rotation of the first transmission gear 22 will drive the transmission belt 17 to rotate. One end of the transmission belt 17 is meshed with the first transmission gear 22 for transmission, and the other end is meshed with the second transmission gear 31 for transmission. The rotation of the transmission belt 17 will drive the second transmission gear 31 to rotate. The two transmission baffles 23 are vertically arranged on both sides of the transmission belt 17. The two transmission baffles 23 can prevent the debris of chemical fiber blended products from flying into the transmission belt 17 during the drawing process. After a period of time, the debris of chemical fiber blended products gradually accumulates and causes device operation failure. Since the material of the transmission belt 17 is soft rubber material, it has certain ductility and plasticity. However, in the actual transmission process, if only the transmission belt 17 is relied upon for transmission, the transmission belt 17 is too soft and cannot achieve the traction effect on the chemical fiber blended products. Therefore, a skeleton needs to be set inside the transmission belt 17 for support. The skeleton of the transmission belt 17 in this device adopts a universal transmission chain 27. The existence of the universal transmission chain 27 can provide support inside the transmission belt 17 without affecting the change of any angle of the transmission belt 17 during the transmission process.

[0053] The connecting end 26 of the hook 24 is fixedly sleeved on the outside of the connecting short rod 29. The tip 25 of the hook 24 extends outward after passing through the transmission belt 17. When the transmission belt 17 rotates, the universal transmission chain 27 set inside the transmission belt 17 will rotate accordingly. The universal ball sleeve 30 is fixedly sleeved on one end of the connecting short rod 29, and the universal ball head 28 is fixedly sleeved on the other end of the connecting short rod 29. When the chemical fiber blended product needs to change its angle during towing, the universal ball sleeve 30 will deflect with the universal ball head 28. The accumulated local deflection will cause the overall movement trajectory of the universal transmission chain 27 to deflect, and the hook 24 can pull the chemical fiber blended product after primary processing. This allows the chemical fiber blended product after primary processing to undergo the next drawing and extrusion without human intervention. In addition, the crochet hooks 24 can evenly pull the chemical fiber textile products, thereby ensuring that the chemical fiber textile products are not damaged due to local pulling during the pulling process. Several crochet hooks 24 are evenly inserted into the chemical fiber textile products, so that the arrangement and combination of the chemical fiber textile products' own silk threads will not be disrupted or interrupted when the chemical fiber textile products are separated from the crochet hooks 24. One end of the transmission toothed belt 21 is meshed with the first transmission gear 22, and the other end is meshed with the second transmission gear 31. When the first transmission gear 22 rotates, the transmission toothed belt 21 can rotate accordingly. At the same time, the rotation of the transmission toothed belt 21 can drive the rotation of the second transmission gear 31. The two connecting baffles 20 are used to connect the transmission toothed belt 21 with the plurality of transmission belt pieces 19. Due to the limitations of the processing technology, the two connecting baffles 20 and the plurality of transmission belt pieces 19 need to be sewn together by the processing personnel during processing, and the connecting short rod 29 needs to be sewn together during sewing, so that the connecting short rod 29 is fixedly connected to the transmission belt piece 19 and the transmission toothed belt 21, so that the transmission toothed belt 21 can drive the connecting short rod 29 to move when it moves. It should be noted that the material of the transmission belt piece 19, the connecting baffle 20 and the transmission toothed belt 21 is all soft rubber material. This material has strong plasticity and soft texture, which is convenient for processing personnel to sew.

[0054] Since the second transmission gear 31 and the first transmission gear 22 are driven by the transmission toothed belt 21, but the transmission belt 21 changes direction many times during the transmission process, its transmission force cannot support the normal rotation of the second transmission gear 31, so the auxiliary gear 39 is used to supplement the power for the second transmission gear 31, and one end of the traction belt 38 is engaged with the auxiliary gear 39, and the other end is engaged with the traction gear 37. The traction gear 37 is fixedly sleeved with the power roller shaft 14, and the rotation of the power roller shaft 14 will drive the rotation of the traction gear 37, and the rotation of the traction gear 37 will be driven by the power roller shaft 14. The traction belt 38 drives the auxiliary gear 39 to rotate. The rotation of the auxiliary gear 39 supplements the power of the second transmission gear 31. The second avoidance groove 4 provides avoidance space for the auxiliary gear 39 to prevent the auxiliary gear 39 from colliding with the support platform during rotation. Several positioning shafts 42 are fixedly inserted in a vertical state on the upper end of the carrying platform 2. The positioning roller 43 is coaxially connected to the positioning shaft 42 in a rolling manner. The positioning shaft 42 is used to change the moving trajectory of the conveyor belt 21. At the same time, the positioning shaft 42 slides with the transmission baffle 23 to assist in limiting the pulled chemical fiber blended products.

[0055] Finally, when the chemical fiber blended product after the initial extrusion and drawing passes through the two drawing extrusion wheels 33. At this time, the two power motors 35 are running, and the two drawing extrusion wheels 33 are respectively fixedly connected to the output shafts of the two power motors 35 coaxially. Then, the operation of the power motors 35 drives the two drawing extrusion wheels 33 to rotate, and the two drawing extrusion wheels 33 turn in opposite directions. The chemical fiber blended product pulled by the hook 24 can be further drawn and extruded by the extrusion part 34. This extrusion is the second drawing extrusion. The chemical fiber blended product after extrusion can be woven and drawn or parallel drawn according to production requirements.

[0056] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
