Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber production equipment, and specifically relates to a reversing end cap sleeve at both ends of a spiral groove of a grooved drum that can be simply replaced. Background Art

[0002] The wire arrangement mechanism of the direct yarn drawing machine is the core component of the wire drawing machine, especially the groove drum (cam) has a direct impact on the yarn ball forming. Since the glass fiber direct yarn drawing winding yarn relies on the shuttle to reciprocate the wire arrangement, the reciprocating motion of the shuttle depends on the positive and negative double spiral grooves on the groove drum. The positive and negative double spiral grooves push the shuttle with the rotation of the groove drum. Under the guidance of the guide plate, the shuttle reciprocates at a high frequency in the positive and negative double spiral grooves of the groove drum to achieve linear reciprocating wire arrangement motion. However, this groove drum double spiral groove wire arrangement has two fatal defects: one is that the service life of the shuttle is too short, the reversing points of the double spiral grooves of the groove drum at both ends are easily impacted and worn, the machine is frequently stopped to replace the shuttle, and the speed cannot be increased, which cannot meet the high-speed wire drawing process; the second is material and processing. Since the multi-point drawing process is basically adopted for wire drawing, the groove drum must also meet the multi-point drawing process, so the groove drum will be longer. In order to increase its own rigidity and wear resistance, the long groove drum is usually processed and hardened in an integral form, but the overall processing is easy to deform and the deformation is greater after hardening, which is difficult to control. There are also contradictions in the selection of materials: since the double spiral groove is suitable for milling, the inner groove is small and easy to wear or break, but the base material must be resistant to strong corrosion, wear and impact. At present, in order to reduce the consumption of the shuttle and the frequent shutdown to replace the shuttle and appropriately increase the running speed, the nylon shuttle material is made of fiber or resin fiber to increase the wear resistance and extend the life of the shuttle. However, while the wear resistance of the shuttle is increased, the hardness is also increased, resulting in excessive impact and excessive wear at the reversing points of the spiral grooves at both ends of the groove barrel.

[0020] Beneficial technical effects: 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 5. The sliding shuttle made of a metal shuttle body and a resin wear-resistant resin cover can also avoid the same-phase wear between the components, further reduce the degree of wear during equipment operation, and extend the service life of the equipment.

DETAILED DESCRIPTION

[0028] Terminology: The forward and reverse spiral grooves on the groove drum are used to drive the shuttle to reciprocate to complete the wire arrangement. When the shuttle moves to the two ends of the forward and reverse spiral grooves, it will automatically reverse. In this application, the two ends of the forward and reverse spiral grooves are called reversing ends or reversing points. Correspondingly, the reversing end head cover refers to the component assembled at the two ends of the spiral groove of the groove drum to drive the shuttle to complete the reversing action.

[0029] See also Figure 1-Figure 4 The simple and replaceable reversing end sleeves at both ends of the spiral groove of the grooved drum disclosed in the present application include 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 parts, and are very convenient to assemble and disassemble.

[0030] The outer end sleeve 130 is provided with a large groove matching portion 110, and the inner end sleeve 140 is provided with a small groove matching portion 120. The large groove matching portion 110 is used to cooperate with the corresponding structure on the sleeve 20 to define the large reversing groove 30, and the small groove matching portion 120 is used to cooperate with the corresponding structure on the groove cylinder 50 to define the small reversing groove 40. The small reversing groove 40 constitutes the groove section of the forward and reverse spiral grooves 510 on the groove cylinder 50 located at both ends of the groove cylinder, and the groove section is also the groove section of the shuttle reversing, so it is also the part most easily damaged by wear and collision.

[0031] When the reversing groove sections at both ends of the forward and reverse spiral grooves of the existing one-piece groove drum are damaged, the machine has to be shut down for maintenance, or even the entire groove drum has to be replaced, which results in high maintenance frequency, long downtime and high maintenance costs.

[0032] The present application discloses a simply replaceable reversing end sleeve at both ends of the spiral groove of the grooved drum. When the groove sections at the reversing points 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 sleeve. This avoids the technical problem in the prior art that the entire grooved drum must be replaced once the groove sections at the reversing points are damaged, which is beneficial to saving production costs, reducing the difficulty of equipment maintenance, and reducing downtime for maintenance.

[0033] 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.

[0034] 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.

[0035] 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 .

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Implementation principle: 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. When the wire arranging shuttle 80 runs to the two ends of the groove drum 50, i.e., the reversing ends, the reversing drive unit 8320 cooperates with the reversing large groove 30, and the reciprocating drive unit 8310 cooperates with the reversing small groove 40. At this time, the driving force of the wire arranging shuttle 80 comes from the reversing drive unit 8320; the shuttle 830 interacts with the reversing end head sleeve at the reversing part 70 of the forward and reverse spiral grooves 510 and then changes direction to perform wire arranging movement in the opposite direction. Since the wear or collision parts during the reversing process mainly occur between the shuttle 830 and the reversing end head sleeve, even if the reversing end head sleeve is damaged, it will not affect the structure and performance of the groove drum 50, so that when repairing, it is not necessary to replace the entire groove drum 50, and production can be resumed immediately by simply disassembling and assembling the reversing end head sleeve.

[0040] In addition, since the reversing end cap is independently formed relative to the grooved barrel 50, a more wear-resistant and bump-resistant material (such as titanium alloy) can be used for the reversing end cap, which is a vulnerable part that operates in a part with greater collision and friction; and the grooved barrel 50 itself is a component that is not easy to be damaged (since it will not cause serious wear and collision with the shuttle during operation), it can still use a more cost-effective material (such as nylon material PA6 / PA66). Furthermore, by configuring the shuttle 830 with a more wear-resistant and harder material, and matching the independently formed reversing end cap with a more wear-resistant, corrosion-resistant and impact-resistant material, the service life of the equipment can be extended to the maximum extent, and the equipment downtime for replacing vulnerable parts and maintenance time can be reduced.

[0041] Furthermore, in the existing integrated groove drum, since the reversing part 70 of the groove drum is on the same side of the axis of the groove drum, it is an asymmetric structure. When the rotation speed of the groove drum is relatively large, the eccentric torque of the groove drum itself is also very large, and the stability and line arrangement accuracy of the equipment during operation will be affected, thereby limiting the increase in the rotation speed of the groove drum, and directly affecting the production efficiency of the wire drawing machine or the winding machine. The reversing end sleeves at both ends of the spiral groove of the simple replaceable groove drum provided in this application can partially solve the problem of eccentric torque through a groove drum structure such as "titanium alloy (reversing end sleeve) + nylon (groove drum body) + titanium alloy (reversing end sleeve)". Although the reversing part 70 in the groove drum structure is also on the same side of the axis of the groove drum, the eccentric torque formed can also be effectively controlled due to the greatly reduced weight of the entire groove drum, thereby allowing the groove drum to have a larger rotation speed, which helps to improve work efficiency. At the same time, due to the reduced weight of the groove drum, the energy consumption of equipment operation and the difficulty and cost of assembling and repairing the groove drum can also be effectively controlled.

[0042] 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.

[0043] 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 6In 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] See also Figure 7-Figure 8 As mentioned above, the sleeve structure of "titanium alloy (reversing end sleeve) + nylon (groove barrel body) + titanium alloy (reversing end sleeve)" in this application allows the groove barrel to have a higher rotation speed, which is conducive to improving production efficiency. At the same time, the combination of the reversing end sleeve and the groove barrel formed by it and the wear-resistant and high-hardness shuttle can also increase the line speed to meet the production of high-end products. In order to cooperate with the high-speed operation of the groove barrel, this application also involves a wear-resistant wire arrangement shuttle.

[0048] The structure and connection assembly relationship of the wear-resistant wire shuttle Figure 5 The differences are: 1. The shuttle 830 includes a shuttle body 8340 and a wear-resistant resin cover 8350. The shuttle body 8340 is provided with a reciprocating drive unit 8310 and a shuttle shaft 8330. The reciprocating drive unit 8310 and the shuttle shaft 8330 are integrally formed. The functions of the reciprocating drive unit 8310 and the shuttle shaft 8330 are the same as those in the above-mentioned embodiment and are not described in detail. The wear-resistant resin cover 8350 is provided with a reversing drive unit 8320, a spacer sleeve connecting unit 8351, and a shuttle shaft tight-fitting hole 8352. The reversing drive unit 8320 and the spacer sleeve connecting unit 8351 are integrally formed. The shuttle shaft tight-fitting hole 8352 penetrates the reversing drive unit 8320 and the spacer sleeve connecting unit 8351. The functions of the reversing drive unit 8320 are the same as those in the above-mentioned embodiment and are not described in detail. The shuttle shaft 8330 is fixedly disposed in the shuttle shaft tight-fitting hole 8352 , the reversing drive portion 8320 extends out of the shuttle shaft tight-fitting hole 8352 , and the reciprocating drive portion 8310 extends out of the reversing drive portion 8320 .

[0049] By adopting the sliding shuttle 830 which is tightly matched with the shuttle body 8340 and the wear-resistant resin cover 8350, the wear-resistant resin cover can be used as a guide at the large reversing groove, and the service life of the reciprocating drive part can be extended by the nylon groove tube material, which can avoid direct rigid wear between the spacer sleeve 820 and the shuttle body 8340, and further increase the wear resistance of the sliding shuttle 830.

[0050] At the same time, the use of the sliding shuttle 830 formed by the metal shuttle body 8340 and the wear-resistant resin cover 8350 made of resin material can also avoid the same-phase wear (wear between the same materials) between the sliding shuttle 830 and the groove drum 50, greatly reducing the wear of the parts. It is generally believed that since the friction coefficients between the same materials are relatively close, it is easier to reach higher temperatures and pressures during the friction process, thereby causing aggravated wear (aggravated adhesive wear).

[0051] In the aforementioned equipment scheme of "titanium alloy (reversing end cover) + nylon (groove drum body) + titanium alloy (reversing end cover)", if a full metal shuttle 830 is used, there will still be unidirectional wear between the shuttle 830 and the reversing end cover. If a nylon shuttle 830 is used, there will also be unidirectional wear between the shuttle 830 and the nylon groove drum 50. The composite shuttle body formed by the tight fit of "metal shuttle body 8340 + wear-resistant resin cover 8350" introduced in this embodiment can solve the problem of unidirectional wear on the wiring shuttle.

[0052] When the shuttle 830 performs reciprocating motion for arranging the wires, a sliding fit occurs between the reciprocating drive part 8310 made of metal and the forward and reverse spiral grooves 510 on the nylon grooved barrel, and the wear between the reciprocating drive part 8310 and the forward and reverse spiral grooves 510 is out-of-phase wear; when the shuttle 830 performs reversing motion, a sliding fit occurs between the reversing drive part 8320 made of resin and the reversing end cover made of metal, and the wear between the reversing drive part 8320 and the reversing end cover (including the end cover 10 and the barrel cover 20) is also out-of-phase wear; when the shuttle 830 performs relative rotation 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 is also out-of-phase wear; thus, the shuttle 830 formed by the tight fit of the shuttle body 8340 made of metal and the wear-resistant resin cover 8350 made of resin can also avoid the same-phase wear between the components, further reduce the degree of wear during the operation of the equipment, and extend the service life of the equipment.

[0053] 2. The wire guide 840 adopts Figure 5 The uniform structure shown is different from the local thickening structure. Specifically, material is added near the opening of the wire guide port 8410 to form a wire guide port thickening structure 8420 to increase the wear resistance of the wire guide port 8410. The aforementioned sleeve structure of "titanium alloy (reversing end sleeve) + nylon (groove barrel body) + titanium alloy (reversing end sleeve)" and the shuttle structure using a wear-resistant resin cover 8350 improve the wear resistance and impact resistance of the wire arranging shuttle 80, but the wire guide port 8410 of the wire guide sheet 840 is still a weak link. By adding material to form a wire guide port thickening structure 8420, this easily worn soft rib can be eliminated, effectively improving the durability of the wire arranging shuttle 80.

[0054] The technical scheme and technical effects of the present application are described in detail above in combination with the drawings and specific embodiments of the specification. It should be noted that technicians in this field can also develop other embodiments on this basis; any simple deformation and equivalent substitution that does not deviate from the innovative concept of the present application are covered by the present application and belong to the scope of protection of this patent.
