Description

Technical Field

[0001] The invention relates to the technical field of chenille weaving machines, in particular to a chenille weaving machine. Background Art

[0002] Chenille spinning machine is a new type of textile equipment used to produce chenille yarn. Due to the soft and comfortable, gentle touch and bright colors of chenille yarn, it is widely used in the production of clothing fabrics, furniture materials, automobile interiors and other fields.

[0003] When the chenille textile machine is working, the wool yarn is first wound onto the inverted triangle cutting blade through the high-speed rotating head. The width of the cutting blade neck determines the length of the pile yarn. Then the pressure roller is fed from the original yarn frame and two core wires are sent out, one of which constitutes the surface core wire of the chenille yarn, and the other constitutes the bottom core wire of the chenille yarn. The wool yarn on the cutting blade is pushed to the blade by the roller, and the blade cuts the wool yarn. The cut wool yarn is clamped between the surface core wire and the bottom core wire on both sides, and then the rotation of the winding spindle is used to make the sheet wool yarn between the two core wires spread out in all directions to become chenille yarn.

[0004] In order to improve the production efficiency of chenille textile machines and improve the quality of finished chenille yarns, the equipment needs to significantly increase its speed, especially in the yarn feeding device, rotary motor and twisting motor. Not only should its working speed be increased, but also its structural stability of long-term high-speed operation should be guaranteed. On the other hand, it is also necessary to flexibly adjust the yarn raw materials of different specifications and the moisture regain of different batches of yarns to ensure the quality and consistency of the finished chenille yarns. The existing chenille textile machines have slow working speeds, complex transmission structures, high failure rates, and high maintenance costs, and are unable to perform high-efficiency and high-quality chenille yarn production. Summary of the invention

[0005] The object of the present invention is to provide a chenille spinning machine which can produce chenille yarn with high efficiency and high quality by means of an improved machine body structure and a controllable motor arrangement.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0008] The left swing arm component and the right swing arm component are arranged in a left-right symmetrical structure, and two mounting holes are symmetrically arranged on the frame. The left swing arm component and the right swing arm component are both provided with mounting bearings, and the mounting bearings can be installed in the corresponding mounting holes. The left swing arm component and the right swing arm component are correspondingly installed with a left swing arm motor and a right swing arm motor on the rear side of the mounting holes.

[0014] Furthermore, the adjusting screw sleeve is connected to the roller shaft via a bearing, the inner ring of the bearing is connected to the roller shaft, and the outer ring of the bearing is connected to the inner wall of the adjusting screw sleeve.

[0015] Furthermore, a limiting nut is arranged on the external thread of the adjusting screw sleeve.

[0016] Furthermore, a wire break alarm component is arranged on the frame, and the wire break alarm component includes an alarm porcelain wheel and a wire break sensor, and the alarm porcelain wheel is arranged between the pressure roller shaft and the roller wheel in the core wire conveying path.

[0017] Furthermore, the spindle assembly includes a spindle motor and a spindle motor flange, and a shock absorbing component is arranged between the spindle motor flange and the frame.

[0018] Compared with the existing technology, this solution has the following advantages:

[0019] The chenille textile machine of this scheme is arranged in a middle-lower structure in a vertical direction through a swivel head assembly, a steel collar plate assembly and a spindle assembly, wherein the main body of the swivel head assembly is arranged through a three-motor independent structure, and the pressure roller motor, the left swing arm motor and the right swing arm motor are independently installed and arranged, and the pressure roller motor realizes the conveying of the core wire with tension maintenance.

[0035] The original intention of this plan is to design a chenille textile machine that can run at high speed and high efficiency, and can freely adjust the speed. The core component of the chenille textile machine, the rotary head assembly, is independently controlled by a motor, so that it can be suitable for various yarn types and batches, and produce high-quality and consistent chenille yarn. The production efficiency of chenille yarn can be greatly improved by increasing the speed and stability.

[0036] refer to Figure 1 A chenille textile machine has a main body of an upper-middle-lower structure, a swivel head assembly is arranged on a frame 19, and a steel collar plate assembly 7 and a spindle assembly 8 that can be raised and lowered synchronously are arranged below the swivel assembly. In the process of making chenille yarn, the swivel head assembly is used to separate the wool yarn and clamp the side-by-side wool yarn segments into two core wires. Then, in the steel collar plate assembly 7 and the spindle assembly 8, a high-speed rotating spindle motor 81 is used to realize the twisting operation, and finally the chenille yarn is made.

[0037] refer to Figures 2 to 5 The swivel head assembly includes a frame 1 and a pressure roller motor 21 arranged on the frame, a left swing arm motor 31 and a right swing arm motor are arranged on the frame 1, wherein the pressure roller motor 21, the left swing arm motor 31 and the right swing arm motor are arranged in a herringbone structure, the left swing arm motor 31 is connected to the left swing arm component 3, the right swing arm motor is connected to the right swing arm component, and the left swing arm component 3 and the right swing arm component are arranged symmetrically (for example to simplify the description, this scheme takes the left swing arm motor 31 and the left swing arm component 3 as an example for further description);

[0038] The roller motor 21 is installed at the center of the top of the frame 1. The rotating shaft 22 of the roller motor 21 is extended to both ends. The roller shafts 23 are connected to the left and right ends. The roller shaft 23 is matched with a roller wheel 24. The roller wheel 24 is an iron core wheel. The rotating shafts at both ends of the roller wheel 24 are limited in the U-shaped groove 25. Therefore, by appropriately changing the diameter of the roller wheel 24 (i.e. adjusting the weight of the iron core counterweight), the roller wheel 24 can always fit with the roller shaft 23. The roller shaft 23 is connected to the roller motor 21. The machine 21 is driven to rotate, and drives the pressure roller 24 to rotate accordingly. On one side of the pressure roller motor 21, the surface core yarn and the bottom core yarn of the chenille delivered from the front end are delivered between the pressure roller 24 and the pressure roller shaft 23 through the wire ring 26. Therefore, by controlling the speed of the pressure roller motor 21, the conveying speed and conveying tension of the two core yarns can be accurately controlled. The core yarns on the left and right sides of the pressure roller motor 21 are respectively delivered to the left swing arm component 31 and the right swing arm component to realize the production of chenille yarn.

[0039] The main body of the frame 1 is a bilaterally symmetrical structure. For the stability of the structure, it can be integrally formed by aluminum alloy castings or milling parts. The frame 1 is symmetrically provided with mounting holes 33. Both the left swing arm component 3 and the right swing arm component are provided with mounting bearings 34. The mounting bearings 34 can be installed in the corresponding mounting holes 33. Specifically, the outer wall of the outer ring of the mounting bearing 34 is tightly fitted with the inner wall of the mounting hole 33. The rear end of the left swing arm component 3 is provided with a hollow mounting seat 35, and the outer wall of the mounting seat 35 is precisely fitted with the inner wall of the inner ring of the mounting bearing 34. Therefore, the left swing arm component 3 can rotate about the center line of the mounting hole 33, the mounting bearing 34 or the mounting seat 35. During actual installation, the left swing arm component 3 is precisely mounted on the frame 1 through the mounting seat 35 and the mounting bearing 34. A motor gear 32 is arranged at the front end of the swing arm motor 31. The left swing arm motor 31 is installed from the rear end to the front end through screws and screw holes on the back of the frame 1. At the same time, the motor gear 32 passes through the central hollow of the mounting seat 35 to transmit power to the inside of the left swing arm component 3, and makes the center line of the rotating shaft of the left swing arm motor 31 coincide with the center line of the mounting bearing 34. Therefore, the installation can be more precise and the power transmission can be more stable. Even if the left swing arm motor 31 is adjusted at a high or low speed, it will not interfere with the rotation of the left swing arm component 3 itself. Therefore, when the speed of the left swing arm motor 31 is freely adjusted, the rotation of the left swing arm component 3 will not be affected, thereby not affecting the pressure of the left swing arm component 3 during the chenille spinning process, so the consistency and quality of the chenille yarn can be improved.

[0040] refer to Figure 6The left swing arm component 3 is hollow inside and is provided with two mutually meshing transmission wheels 36. A roller shaft component 4 is longitudinally arranged on the inner side of the top of the left swing arm component 3. The roller shaft component 4 includes a roller shaft 41. A roller shaft gear 42 is provided in the middle position of the roller shaft 41. The roller shaft gear 42 and the transmission wheel 36 are also in a meshing state. In terms of transmission, the left swing arm motor 31 transmits power to the roller shaft gear 42 and the roller shaft 41 through the left swing arm motor gear 32 and the transmission wheel 36. In this structure, there is no need for traditional couplings and other components, that is, as long as the left swing arm motor 31 is installed in place, the function of efficient and accurate transmission can be realized, which greatly simplifies the equipment installation operation and debugging process, and simplifies the transmission structure, thereby improving the transmission efficiency of the motor and the whole.

[0041] A cover plate 37 is provided on the top of the left swing arm component 3, and the cover plate 37 is installed on the top of the left swing arm component 3 by screws. Opening the cover plate 37 can facilitate installation and maintenance operations. When necessary, lubricant can be added to the inside of the left swing arm component 3, thereby ensuring that the internal gear transmission structure is lubricated and improving its service life and stability.

[0042] refer to Figure 7 Figure 8 The roller shaft 41 is stably installed inside the left swing arm component 3 through two roller bearings 43. At the front end of the roller shaft 41, a roller chuck 46, a roller wheel 47 and a roller cover plate 48 are arranged respectively, wherein the outer ring of the roller wheel 47 can be made of polyurethane material, and the surface core wire of the chenille yarn is transported around the roller disc 47. The roller chuck 46 and the roller cover plate 48 are used to install and fix the roller disc 47 on the roller shaft 41, wherein the front end of the roller cover plate 48 is provided with a mounting straight groove, and the hexagon socket mounting screw 49 is installed with the inside of the roller shaft 41 through a thread. During the installation process, the rotation of the roller cover plate 48 can be first limited by a wrench, and then by The mounting screw 49 is installed with an Allen wrench. Since the outer ring of the roller wheel 47 will wear out during the efficient production of chenille yarn, regular maintenance and replacement operations are required. The installation structure of this scheme has the characteristics of simple structure and convenient installation. It will not affect the rotation of the roller shaft 41 during the installation process, and prevent the roller shaft 41 from affecting the transition wheel 36 and the left swing arm motor 31 in the reverse direction due to the installation force; an oil seal 45 is provided on the roller shaft 41 between the roller bearing 43 and the roller chuck 46 to prevent the lubricating oil inside the left swing arm component 3 from overflowing or invading the roller wheel 47, thereby contaminating the yarn.

[0043] The position and rotation speed of the roller wheel 47 are important parameters for ensuring the quality of the chenille yarn. In order to accurately adjust the front and rear positions of the roller wheel 47, a distance fine-tuning component 400 is arranged at the rear end of the roller shaft 41. The distance fine-tuning component 400 includes an adjusting screw sleeve 401. The adjusting screw sleeve 401 is a hollow structure, and the hollow interior can accommodate the roller shaft 41. The outer wall of the adjusting screw sleeve 401 is provided with an external thread, and the inner wall of the shell of the left swing arm component 3 is provided with an internal thread, and the external thread and the internal thread can cooperate. The adjusting screw sleeve 401 and the roller shaft 41 are in a center-aligned arrangement state, and a bearing cavity 402 is provided at the rear end of the adjusting screw sleeve 401. The bearing cavity 402 can accommodate a fine-tuning bearing 403, that is, the outer ring of the fine-tuning bearing 403 The outer wall fits with the bearing cavity 402, and the inner wall of the inner ring of the fine-tuning bearing 403 fits with the outer wall of the rear end of the roller shaft 41. A shaft end retaining ring 404 is arranged at the outer end of the fine-tuning bearing 403 to cover the outer edge of the fine-tuning bearing 403. The shaft end retaining ring 404 is installed on the outer end of the roller shaft 41 through the retaining ring screw 405, thereby realizing the longitudinal displacement connection between the adjusting screw sleeve 401 and the roller shaft 41, but the rotation between the roller shaft 41 and the adjusting screw sleeve 401 is not subject to mutual interference. In actual operation, by rotating the adjusting screw sleeve 401, under the adjustment of the thread and the internal thread stroke, and through the fine-tuning bearing 403, the roller shaft 41 can be driven to move forward and backward, and then the position of the corresponding roller wheel 47 can be adjusted.

[0044] In order to make the adjustment position relatively stable and prevent the adjusting screw sleeve 401 from rotating during the operation of the left swing arm component 3, a limiting nut 408 is arranged on the external thread of the adjusting screw sleeve 401. The side wall of the limiting nut 408 can fit with the shell of the left swing arm component 3 to play a locking role, thereby preventing the adjusting screw sleeve 401 and the roller shaft 41 from being displaced after the adjustment is completed.

[0045] In order to play a sealing role, a sealing groove 406 is arranged on the outer wall of the front end of the adjusting screw sleeve 401, and an O-ring is arranged correspondingly in the sealing groove 406 to play the role of an oil seal; in order to reduce the impact on the gear transmission when the position of the roller shaft 41 is fine-tuned, the width of the roller shaft gear 42 is greater than the width of the transmission wheel 36, so it can be used to fine-tune the displacement tolerance of the roller shaft 41.

[0046] In order to detect whether the yarn is conveyed normally, a broken wire alarm component 11 is arranged on the frame 1, and the broken wire alarm component 11 includes an alarm ceramic wheel 12 and a broken wire sensor 13, wherein the alarm ceramic wheel 12 is arranged between the pressure roller shaft 23 and the roller wheel 47 in the core wire conveying path. Specifically, the broken wire sensor 13 can be a Hall sensor structure. When the yarn passes through the alarm ceramic wheel 12, it drives the alarm ceramic wheel 12 to rotate continuously, and obtains a voltage value of the corresponding frequency at the broken wire sensor 13. When the broken wire occurs, the broken wire sensor 13 cannot obtain the corresponding voltage value, so the system can determine that the broken wire occurs, and when necessary, the system can implement a shutdown operation; furthermore, through the analysis of the voltage value change of the broken wire sensor 13, the system can be used to obtain the current yarn conveying speed. Since the yarn conveyed between the pressure roller shaft 23 and the roller wheel 47 has a stable tension, the data acquisition has better accuracy.

[0047] refer to Figures 9 to 11 The rotary motor assembly 5 includes a rotary motor 50 and a rotary disk 52. The rotary motor 50 is arranged in a vertical direction and is arranged in the middle position of the top of the frame 1. The rotary motor shaft 51 of the rotary motor 50 is a hollow structure, and both ends of the rotary motor shaft 51 pass through the rotary motor 50. Specifically, the rotary motor shaft 51 is a part of the rotor of the rotary motor 50, and the hollow interior is used to transport the wool yarn. The rotary disk 52 is installed at the lower end position of the rotary motor shaft 51. The rotary motor shaft 51 is provided with a straight groove 53 that passes through the hollow structure horizontally. A wear-resistant ring 54 is arranged at the top position of the rotary motor shaft 51. A wear-resistant ring 54 is also arranged inside the rotary motor shaft 51 above the straight groove 53. The two wear-resistant rings 54 are arranged relative to each other.

[0048] Specifically, the wear-resistant ring 54 can be made of wear-resistant materials such as ceramics or glass, and its inner wall has a smooth arc structure, which can efficiently transport the wool yarn and reduce the wear on the wool yarn. At the same time, due to its excellent wear resistance, it will not have cracks after long-term use, thereby preventing the wool yarn from being cut off. The outer edge of the wear-resistant ring 54 has a concave structure and can be firmly installed on the rotary motor shaft 51 by interference fit. A dust cover 55 is installed at the top position of the rotary motor shaft 51. The dust cover can be made of flexible materials such as rubber, which can prevent the fluff or fine fibers generated during the wool yarn transportation process from entering the rotary motor 50 through the gap.

[0049] The turntable 52 is installed at the bottom of the rotating motor shaft 51, and two wire guide holes 56 are arranged diagonally on the outer circle thereof, that is, the connecting line of the two wire guide holes 56 passes through the center of the turntable 52, and a wire guide hole wear-resistant part 57 is arranged at the wire guide hole 56. The wire guide hole wear-resistant part 57 is also made of wear-resistant materials such as ceramic or glass, and its inner wall is a smooth arc structure, which can efficiently transport the wool yarn and reduce the wear on the wool yarn. The middle part of the outer edge of the wire guide hole wear-resistant part 57 has a groove, which can be firmly installed on the turntable 52.

[0050] At the bottom of the turntable 52, fins 58 are arranged. Specifically, the fins 58 are arranged upright and perpendicular to the line connecting the two wire guide holes 56. That is, in order to achieve dynamic balance of the turntable 52, the fins 58 and the wire guide holes 56 are arranged with their centers aligned at 90 degrees. When the turntable 52 rotates at a high speed, the fins 58 can produce the effect of a centrifugal fan, blowing out the fluff or fine fibers of the wool yarn during the winding and conveying process to prevent their accumulation.

[0051] In order to improve the installation stability, the turntable 52 and the rotary motor shaft 51 are installed and fixed by a conical bolt 59. Specifically, the top of the conical bolt 59 has a conical structure, and the inside of the rotary motor shaft 51 has a conical concave structure. The top of the conical bolt 59 has a hexagonal structure. During installation, the conical bolt 59 is inserted into the inside of the rotary motor shaft 51 through the straight groove 53, and the turntable 52 is installed at the bottom and fixed by screws, and the top is fixed and installed by a hexagonal screwdriver. Therefore, when the turntable 52 runs at high speed, it has self-locking ability, and the more it rotates, the more stable it is, which prevents the traditional bolts from loosening.

[0052] The cutting knife assembly 6 includes a cutting distance piece 60, a blade 64, a blade adjustment frame 66 and a knife holder shaft 65. The sharp surface of the blade 64 is arranged upward and is installed on the top of the blade adjustment frame 66. A straight hole 69 is provided at the bottom of the blade adjustment frame 66. The knife holder shaft 65 is a cylindrical structure with a smooth surface and is arranged in a horizontal direction. The straight hole 69 can cooperate with the knife holder shaft 65. The blade adjustment frame 66 can be arranged on the knife holder shaft 65 through the straight hole 69, and can make the blade adjustment frame 66 move forward and backward on the knife holder shaft 65.

[0053] The cutting piece 60 is arranged below the center of the rotary motor 50. The main body of the cutting piece 60 is a herringbone structure, the top of which is an inverted triangle structure, and a neck structure is arranged at the lower end. The width of the neck structure is the width of the wool thread cutting. At the neck, the wool thread is cut front and back and left and right into multiple short strip structures by the blade, so the sharp surface of the blade 64 is just arranged at the center of the neck. It is divided into left and right pieces below the cutting piece 60, which are respectively installed on the left and right sides of the cutting piece seat 61 through a screw structure. During actual installation, the cutting piece seat 61 is installed on the mounting portion 15 of the frame 1 through a cutting piece mounting block 62. A long waist hole in the vertical direction is arranged on the cutting piece seat 61, and it is installed with the mounting block 62 by screws passing through the long waist hole, and finally installed on the mounting portion 15. Therefore, through the long waist hole, the cutting piece 62 can slightly adjust the up and down position, so that the cutting piece 60, especially its neck position, can cooperate with the left and right roller wheels.

[0054] In the installation of the blade 64, the rear end of the tool holder shaft 65 is installed on the mounting portion 15 of the frame 1 through the tool holder shaft seat 67, and is located directly below the mounting seat 62. A fastening bolt 68 is arranged on the tool holder shaft seat 67 for installing and fixing the tool holder shaft 67. By releasing the fastening bolt 68, the tool holder shaft 65 can be quickly and conveniently removed from the tool holder shaft seat 67.

[0055] The blade adjustment frame 66 can be arranged on the tool holder shaft 65 through the straight hole 69, and a first mounting clamp and a second mounting clamp are installed on the upper end of the blade adjustment frame 66. The bottom of the first mounting clamp is fixed to the top of the blade adjustment frame 66 by a screw structure, and the second mounting clamp is fixed to the first mounting clamp by a screw structure, so that the blade 64 can be stably installed between the first mounting clamp and the second mounting clamp, and the center line of the blade 64 (especially the cutting line of the sharp surface of the blade) is parallel and aligned with the center line of the tool holder shaft 65.

[0056] The frame 1 is a left-right symmetrical structure, with a mounting portion 15 provided at the vertical center, and a vertical mounting groove 16 provided on the front side of the mounting portion 15. During installation, both sides of the tool holder shaft seat 67 and the rear end of the mounting block 62 are restricted in the mounting groove 16, so the tool holder shaft seat 67 and the mounting block 62 can be stably installed on the frame 1 in a vertically aligned manner. There are also long waist holes on both sides of the tool holder shaft seat 67, so that the tool holder shaft seat 67 can be adjusted up and down under the left and right restrictions of the mounting groove 16.

[0057] During the actual installation process, the cutting piece seat 61 and the tool holder shaft seat 67 can be adjusted vertically up and down in accordance with different core wire or wool yarn requirements, so that the isolation piece 60 and the blade 64 can meet the production requirements. Initially, the blade adjustment frame 66 is at the outer end position of the tool holder shaft 65, that is, the rear end of the blade 64 matches the neck position of the cutting piece 60. After using it for a certain period of time, when the corresponding blade 64 becomes relatively blunt due to cutting, a slight external force can be applied to the blade adjustment frame 66 to make it move slightly inward, and drive the blade 64 to move quickly inward by some positions, so that the cutting position of the blade 64 is replaced with a sharp surface, so that the cutting of the wool yarn can be kept stable, thereby realizing continuous and stable chenille yarn production for a long time.

[0058] refer to Fig.13 , after the two core wires are transported to the corresponding roller wheels 47 through the pressure roller motor 21, the tension of the core wire between the two can be freely adjusted by the pressure roller motor 21 and the left swing arm 47, and then the wool thread is segmented and cut into multiple wool thread segments by the blade 64 at the cutting piece 60, and the wool thread segments are clamped between the two core wires, and then under the high-speed rotation of the steel collar plate assembly 7 and the spindle motor assembly 8, the twisting function is realized, and finally chenille yarn is made. In order to cope with the high-speed rotating spindle motor 81, a shock-absorbing component 83 is arranged between the spindle motor flange 82 and the frame 19. Specifically, the shock-absorbing component 83 can be a shock-absorbing rubber block or a damping bearing, which can reduce the transmission of vibration and reduce resonance, and can greatly improve the working stability of the spindle motor.
