Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production equipment, and specifically relates to a simple replaceable reversing end sleeve at both ends of the spiral groove of the grooved drum. Background Technique

[0002] The wire arranging mechanism of a direct yarn drawing machine is the core component of the drawing machine. In particular, the grooved drum (cam) has a direct impact on the formation of the yarn bobbin. Since the winding of glass fiber direct yarn depends on the reciprocating wire arrangement of the sliding shuttle, the reciprocating motion of the sliding shuttle depends on the positive and negative double spiral grooves on the grooved drum. The positive and negative double spiral grooves push the sliding shuttle as the grooved drum rotates. Under the guidance of the guide plate, the sliding shuttle makes high-frequency reciprocation in the positive and negative double spiral grooves of the grooved drum to achieve linear reciprocating wire arrangement motion. However, this wire arrangement with double spiral grooves on the grooved drum has two fatal defects: one is that the service life of the sliding shuttle is too short, the impact at the reversing points at both ends of the double spiral grooves on the grooved drum is large and it is easy to wear, the sliding shuttle needs to be replaced frequently during shutdown, and the speed cannot be increased, etc., which cannot meet the high wire speed drawing process; the second is the material and processing. Since the multi-strand drawing process is basically adopted for drawing now, the grooved drum also needs to meet the multi-strand drawing process, so the grooved drum will be longer. In order to increase its own rigidity and wear resistance, the long grooved drum is usually processed and hardened as a whole, but it is easy to deform during the overall processing and the deformation is even greater after the hardening treatment, which is very difficult to control. There are also contradictions in the material selection: since the double spiral grooves are suitable for milling cutter processing and the inner groove is small, it is easy to wear or break the cutter, but the base material must have characteristics such as strong corrosion resistance, wear resistance and impact resistance. At present, in order to reduce the consumption of the sliding shuttle and the frequent shutdown for replacing the sliding shuttle and appropriately increase the running speed, the nylon sliding shuttle material is made by adding fibers or resin fibers to increase the wear resistance and extend the service life of the sliding shuttle. However, while increasing the wear resistance of the sliding shuttle, the hardness is also increased, resulting in excessive impact and too fast wear at the reversing points at both ends of the spiral groove of the grooved drum.

[0021] Beneficial technical effects:

[0022] 1. The reversing end sleeves at both ends of the spiral groove of the grooved drum disclosed in the present application can be assembled on the grooved drum and form groove sections at the reversing locations of the double spiral grooves at both ends of the grooved drum by cooperating with corresponding structures on the grooved drum. Therefore, when the groove sections at the reversing locations of the double spiral grooves at both ends of the grooved drum are severely worn, the grooved drum can be maintained by simply replacing the reversing end sleeves, thus avoiding the technical problem in the prior art that the entire grooved drum must be replaced once the groove sections at the reversing locations are damaged, thereby being beneficial to saving production costs, reducing the difficulty of equipment maintenance, and reducing downtime for maintenance.

[0023] 2. Since the reversing end sleeve is formed independently of the grooved barrel, the reversing end sleeve, a vulnerable part that operates in a part with large collision and friction, can be made of a more wear-resistant, corrosion-resistant, and impact-resistant material; and the grooved barrel itself is a part that is not easily damaged, and a more cost-effective material can still be used. Based on this, the shuttle can also be equipped with a more wear-resistant and harder material, and with the independently formed reversing end sleeve, the service life of the equipment can be maximized, and the equipment downtime for replacement of vulnerable parts and maintenance time can be reduced. At the same time, the reversing end sleeve and the grooved barrel formed by it are combined with the wear-resistant and high-hardness shuttle, which can also increase the line speed and meet the production of high-end products.

[0024] 3. The reversing end sleeve and the grooved cylinder formed thereby disclosed in the present application can be used to form a multi-part elongated grooved cylinder, thereby reducing the processing difficulty of the existing one-piece long grooved cylinder, improving the processing accuracy of the forward and reverse spiral grooves, and reducing the equipment manufacturing, operation, maintenance and overhaul costs by several times.

[0025] 4. The use of a shuttle equipped with a reciprocating drive unit and a reversing drive unit can disperse the wear and tear of the shuttle during operation to different parts of the shuttle (reciprocating drive unit, reversing drive unit), which helps to extend the service life of the equipment.

[0026] 5. The use of a sliding shuttle composed of a shuttle body made of metal material and a wear-resistant resin cover made of resin material can also prevent in-phase wear between components, further reduce the wear degree during the operation of the equipment, and extend the service life of the equipment.

[0047] Term description: The positive and negative spiral grooves on the grooved drum are used to drive the shuttle to reciprocate to complete the wire arranging action. When the shuttle moves to both ends of the positive and negative spiral grooves, automatic reversing is required. In this application, both ends of the positive and negative spiral grooves are called the reversing end or reversing point. Correspondingly, the reversing end head sleeve refers to the component assembled at both ends of the spiral groove of the grooved drum to drive the shuttle to complete the reversing action.

[0048] Please refer to Figures 1 - 4 , the simply replaceable reversing end head sleeve at both ends of the spiral groove of the grooved drum disclosed in this application includes an end sleeve 10 and a barrel sleeve 20; the end sleeve 10 includes an outer end sleeve 130 and an inner end sleeve 140. The outer end sleeve 130, the inner end sleeve 140 and the barrel sleeve 20 are all separately formed components, and the assembly and disassembly are very convenient.

[0049] A large groove coordination part 110 is provided on the outer end sleeve 130, and a small groove coordination part 120 is provided on the inner end sleeve 140. The large groove coordination part 110 is used to cooperate with the corresponding structure on the barrel sleeve 20 to define a reversing large groove 30, and the small groove coordination part 120 is used to cooperate with the corresponding structure on the grooved drum 50 to define a reversing small groove 40. The reversing small groove 40 constitutes the groove section at both ends of the positive and negative spiral grooves 510 on the grooved drum 50. This groove section is also the groove section where the shuttle reverses, and thus is the part most easily damaged due to wear and collision.

[0050] When the reversing groove section at both ends of the positive and negative spiral grooves of the existing integral grooved drum is damaged, it is necessary to stop the machine for maintenance, and even the entire grooved drum needs to be replaced. The maintenance frequency is high, the downtime is long, and the maintenance cost is high.

[0051] The simply replaceable reversing end head sleeve at both ends of the spiral groove of the grooved drum disclosed in this application can maintain the grooved drum by simply replacing the reversing end head sleeve when the groove section at both ends of the double spiral grooves on the grooved drum is severely worn. This avoids the technical problem in the prior art that once the groove section at the reversing point is damaged, the entire grooved drum must be replaced, which is beneficial to saving production costs, reducing the difficulty of equipment maintenance, and reducing the downtime for maintenance.

[0052] The sleeve 20 is provided with a large groove defining portion 210, and the grooved cylinder 50 is provided with a positive and negative spiral groove 510, an end sleeve fitting 520, and a small groove defining portion 530. The end sleeve fitting 520 is located at both ends of the positive and negative spiral groove 510, and the small groove defining portion 530 faces the end sleeve fitting 520.

[0053] The inner end sleeve 140 is fixedly assembled in the end sleeve fittings 520 at both ends of the grooved drum 50, the outer end sleeve 130 is fixedly assembled on the inner end sleeve 140, and the cylinder sleeve 20 is fixedly assembled on the grooved drum 50 to avoid the forward and reverse spiral grooves 510 and close to the end sleeve 10.

[0054] A large reversing groove 30 is defined between the large groove coordinating portion 110 and the large groove defining portion 210 , and a small reversing groove 40 is defined between the small groove coordinating portion 120 and the small groove defining portion 530 . The small reversing groove 40 is located inside the large reversing groove 30 .

[0055] The fixed connection between the outer end sleeve 130, the inner end sleeve 140, the barrel sleeve 20 and the sleeve 50 can be completed by using common fasteners such as screws and screw holes. For example, assembly holes are respectively provided on the outer end sleeve 130, the inner end sleeve 140, the barrel sleeve 20, and the grooved barrel 50, and then the fastening connection is achieved by screws.

[0056] See also Figure 5 The wire arrangement shuttle 80 used in conjunction with the reversing end sleeves at both ends of the spiral groove of the simple replaceable groove drum disclosed in the present application includes a slider 810, a spacer 820, a shuttle 830, and a wire guide 840. The slider 810 is provided with a slide rail groove 8110 and a spacer hole 8120. The spacer 820 is provided with a shuttle hole 8210 and a baffle 8220. The shuttle 830 is provided with a reciprocating drive unit 8310, a reversing drive unit 8320, and a shuttle shaft 8330.

[0057] The wire guide sheet 840 is fixedly assembled on the slider 810, the spacer sleeve 820 is arranged in the spacer sleeve hole 8120, the shuttle shaft 8330 is arranged in the shuttle hole 8210 on the spacer sleeve 820, the reciprocating drive unit 8310 and the reversing drive unit 8320 extend out of the baffle plate 8220, and the slide rail groove 8110 is used to cooperate with the corresponding slide rail to increase the stability of the movement of the wire shuttle.

[0058] Implementation principle:

[0059] The groove drum 50 rotates under the drive of the groove drum motor, driving the wire shuttle 80 to move within the range of the forward and reverse spiral grooves 510. At this time, the reciprocating drive part 8310 and the forward and reverse spiral grooves 510 cooperate with each other, and the driving force of the wire shuttle 80 comes from the reciprocating drive part 8310.

[0060] When the wire arranging shuttle 80 runs to both ends of the grooved drum 50, i.e., the commutation ends, the commutation driving part 8320 cooperates with the large commutation groove 30, and the reciprocating driving part 8310 cooperates with the small commutation groove 40. At this time, the driving force of the wire arranging shuttle 80 comes from the commutation driving part 8320; the shuttle 830 interacts with the commutation end head sleeve at the commutation part 70 of the positive and negative spiral grooves 510 and then changes direction to perform wire arranging movements in opposite directions. Since the wear or collision during the commutation process mainly occurs between the shuttle 830 and the commutation end head sleeve, even if the commutation end head sleeve is damaged, it will not affect the structure and performance of the grooved drum 50. Therefore, when performing maintenance, there is no need to replace the entire grooved drum 50, and only simple disassembly and assembly of the commutation end head sleeve are required to resume production immediately.

[0061] In addition, since the commutation end head sleeve is independently formed relative to the grooved drum 50, more wear-resistant and impact-resistant materials (such as titanium alloy materials) can be used for the commutation end head sleeve, which is a vulnerable part operating in a position with large collision and friction; while the grooved drum 50 itself is a part that is not easily damaged (because there will be no serious wear and collision with the shuttle during operation), and a material with a relatively high cost performance (such as nylon materials PA6 / PA66) can still be used. Furthermore, by configuring the shuttle 830 with more wear-resistant and higher-hardness materials, and cooperating with the independently formed commutation end head sleeve with more wear-resistant, corrosion-resistant, and impact-resistant materials, the service life of the equipment can be extended to the maximum extent, and the time for the equipment to stop for replacing vulnerable parts and maintenance can be reduced.

[0062] Moreover, in the existing integral grooved drum, since the commutation part 70 of the grooved drum is on the same side of the axis of the grooved drum and is an asymmetric structure, when the rotational speed of the grooved drum is relatively high, the eccentric moment of the grooved drum itself is also very large, and the stability and wire arranging accuracy during equipment operation will be affected, thus restricting the increase of the rotational speed of the grooved drum and directly affecting the production efficiency of the wire drawing machine or the winding machine. The simple replaceable commutation end head sleeves at both ends of the spiral groove of the grooved drum provided in this application can partially solve the problem of the eccentric moment through the grooved drum structure of "titanium alloy (commutation end head sleeve) + nylon (grooved drum body) + titanium alloy (commutation end head sleeve)". Although the commutation part 70 in this grooved drum structure is also on the same side of the axis of the grooved drum, due to the significant reduction in the overall weight of the grooved drum, the formed eccentric moment can also be effectively controlled, thereby allowing the grooved drum to have a relatively high rotational speed, which helps to improve the working efficiency. At the same time, since the weight of the grooved drum is reduced, the energy consumption during equipment operation and the difficulty and cost during the assembly and maintenance of the grooved drum can also be effectively controlled.

[0063] In addition, as mentioned above, when the wire shuttle 80 runs within the range of the forward and reverse spiral grooves 510 on the groove drum 50, the driving force mainly comes from the reciprocating drive part 8310, so that the wear also mainly occurs on the reciprocating drive part 8310; when the wire shuttle 80 runs to the two ends of the groove drum 50, that is, the reversing end, the driving force mainly comes from the reversing drive part 8320, so that the wear also mainly occurs on the reversing drive part 8320; therefore, the reversing end head cover at both ends of the spiral groove of the simply replaceable groove drum disclosed in the present application can also disperse the wear of the shuttle 830 during the working process to different parts of the shuttle (reciprocating drive part 8310, reversing drive part 8320), which helps to reduce accumulated wear and reduce the cost of equipment manufacturing, operation, maintenance and overhaul.

[0064] Furthermore, the simple and replaceable reversing end sleeves at both ends of the spiral groove of the grooved drum and the grooved drum formed by the same disclosed in the present application can also help reduce the processing difficulty of the long grooved drum and meet the application requirements of the multi-branch drawing process and equipment for the long grooved drum. Figure 6 In one embodiment of the present application, a grooved cylinder shaft 60 is further included, and a plurality of grooved cylinders 50 are fixedly assembled on the grooved cylinder shaft 60 to form a plurality of elongated grooved cylinders. The grooved cylinder 50 and the grooved cylinder shaft 60 are fixedly connected by the grooved cylinder shaft hole 540 on the grooved cylinder 50 and the grooved cylinder shaft 60 and by fasteners such as screws. A reversing end cap is provided at both ends of each grooved cylinder 50. The connection method between the reversing end cap and the grooved cylinder 50 is not described in detail.

[0065] The use of a plurality of grooved cylinders 50 and reversing end sleeves to form a multi-part elongated grooved cylinder can, on the one hand, reduce the difficulty of processing the existing one-piece long grooved cylinder and improve the processing accuracy of the forward and reverse spiral grooves; on the other hand, it can also reduce the maintenance and repair costs of the equipment by several times.

[0066] In addition, it should be noted that the outer end sleeve 130 and the inner end sleeve 140 in the present application can also adopt an integrally formed structure, that is, the large groove coordination portion 110 and the small groove coordination portion 120 respectively arranged on the outer end sleeve 130 and the inner end sleeve 140 in the above embodiment are both arranged on the integrally formed end sleeve 10. The shape and position relationship between the large groove coordination portion 110 and the small groove coordination portion 120 is the same as that in the above embodiment, and will not be repeated here.

[0067] In a modified embodiment of the present application, an integrally formed structure is adopted between the barrel sleeve 20 and the groove barrel 50. The shape and position relationship of the large groove defining portion 210 on the barrel sleeve 20 is the same as that of the above embodiment, and will not be repeated here.

[0068] See also Figures 7 - 8, as previously mentioned, the sleeve structure of "titanium alloy (commutation end sleeve) + nylon (bobbin body) + titanium alloy (commutation end sleeve)" in this application allows the bobbin to have a relatively high rotational speed, which is conducive to improving production efficiency. At the same time, the commutation end sleeve and the bobbin composed of it, in combination with the wear-resistant, high-hardness and smooth shuttle, can also increase the linear speed and meet the production of high-end products. To cooperate with the high-speed operation of the bobbin, this application also relates to a wear-resistant wire arranging shuttle.

[0069] The structure and connection and assembly relationship of the wear-resistant wire arranging shuttle are the same as those of the wire arranging shuttle shown in Figure 5 . The difference lies in:

[0070] 1. The shuttle 830 includes a shuttle body 8340 and a wear-resistant resin cover 8350. A reciprocating drive portion 8310 and a shuttle shaft 8330 are provided on the shuttle body 8340. The reciprocating drive portion 8310 and the shuttle shaft 8330 are integrally formed. The functions of the reciprocating drive portion 8310 and the shuttle shaft 8330 are the same as those in the foregoing embodiments and will not be elaborated. A commutation drive portion 8320, a spacer connection portion 8351, and a shuttle shaft tight-fitting hole 8352 are provided on the wear-resistant resin cover 8350. The commutation drive portion 8320 and the spacer connection portion 8351 are integrally formed. The shuttle shaft tight-fitting hole 8352 penetrates through the commutation drive portion 8320 and the spacer connection portion 8351. The function of the commutation drive portion 8320 is the same as that in the foregoing embodiments and will not be elaborated. The shuttle shaft 8330 is fixedly arranged in the shuttle shaft tight-fitting hole 8352, the commutation drive portion 8320 extends out of the shuttle shaft tight-fitting hole 8352, and the reciprocating drive portion 8310 extends out of the commutation drive portion 8320.

[0071] By adopting the shuttle 830 tightly fitted by the shuttle body 8340 and the wear-resistant resin cover 8350, it can not only realize the guiding of the wear-resistant resin cover at the commutation large groove, but also extend the service life of the reciprocating drive portion through the nylon bobbin material, and can avoid the direct rigid wear between the spacer 820 and the shuttle body 8340, further increasing the wear resistance of the shuttle 830.

[0072] At the same time, by adopting the shuttle 830 tightly fitted by the shuttle body 8340 made of metal material and the wear-resistant resin cover 8350 made of resin material, it can also avoid the in-phase wear (wear occurring between the same materials) between the shuttle 830 and the bobbin 50, greatly reducing the wear degree of the components. Generally, it is considered that since the friction coefficients between the same materials are relatively close, it is easier to reach a relatively high temperature and pressure during the friction process, resulting in aggravated wear (aggravated adhesive wear).

[0073] In the foregoing equipment solution of "titanium alloy (commutating end sleeve) + nylon (bobbin body) + titanium alloy (commutating end sleeve)", if a fully metal sliding shuttle 830 is used, there will still be co-directional wear between the sliding shuttle 830 and the commutating end sleeve. If a nylon sliding shuttle 830 is used, there will also be co-directional wear between the sliding shuttle 830 and the nylon bobbin 50. The composite shuttle body formed by tightly fitting the "metal shuttle body 8340 + wear-resistant resin cover 8350" introduced in this embodiment can solve the problem of co-directional wear on the wire arranging sliding shuttle.

[0074] When the sliding shuttle 830 makes a reciprocating wire arranging movement, a sliding fit occurs between the reciprocating driving part 8310 made of metal and the positive and negative spiral grooves 510 on the nylon bobbin. The wear between the reciprocating driving part 8310 and the positive and negative spiral grooves 510 belongs to out-of-phase wear. When the sliding shuttle 830 makes a commutation movement, a sliding fit occurs between the commutation driving part 8320 made of resin and the commutating end sleeve made of metal. The wear between the commutation driving part 8320 and the commutating end sleeve (including end sleeve 10 and barrel sleeve 20) also belongs to out-of-phase wear. When the sliding shuttle 830 rotates relatively between the spacer sleeves 820, the wear between the spacer sleeve connecting part 8351 made of resin and the spacer sleeve 820 made of metal also belongs to out-of-phase wear. Therefore, the sliding shuttle 830 formed by tightly fitting the shuttle body 8340 made of metal and the wear-resistant resin cover 8350 made of resin can also avoid in-phase wear between components, further reduce the wear degree during the operation of the equipment, and extend the service life of the equipment.

[0075] 2. The wire guiding piece 840 adopts a partial thickening structure different from the uniform structure shown in Figure 5 Specifically, a wire guiding port thickening structure 8420 is formed by adding materials near the opening part of the wire guiding port 8410 to increase the wear resistance of the wire guiding port 8410. The foregoing sleeve structure of "titanium alloy (commutating end sleeve) + nylon (bobbin body) + titanium alloy (commutating end sleeve)" and the sliding shuttle structure with the wear-resistant resin cover 8350 improve the wear resistance and impact resistance of the wire arranging sliding shuttle 80. However, the wire guiding port 8410 of the wire guiding piece 840 is still a weak link. By adding materials to form the wire guiding port thickening structure 8420, this easily worn soft rib can be eliminated, effectively improving the durability of the wire arranging sliding shuttle 80.

[0076] The technical solutions and technical effects of the present application have been elaborated in detail above in combination with the specification drawings and specific embodiments. It should be noted that those skilled in the art can also develop other embodiments on this basis; any simple deformation and equivalent replacement that do not depart from the innovative concept of the present application are covered by the present application and belong to the protection scope of this patent.
