Description

TECHNICAL FIELD

[0001] The present application relates to the field of plate strip polishing, in particular to a threading mechanism and a threading method. BACKGROUND

[0002] The plate strip is usually made by hot rolling process, and before actual use, the surface of the plate strip will produce rust, scale and the like, which needs to be polished by a brush roll. In order to facilitate disassembly and maintenance, a brush roll structure is provided with a plurality of polishing brush discs sleeved on the roll shaft. The polishing brush disc is provided with a plurality of wire holes uniformly distributed in the circumferential direction on the inner side, and a plurality of parallel material wires made of resin material are arranged in the wire holes. The plurality of parallel material wires are folded in half along the radial direction away from the brush disc to form two sub-material wires on both sides of the brush disc. The two sub-material wires are fixed to each other and form a wire bundle for polishing the surface of the plate strip.

[0003] The manual threading method is too low in efficiency. In order to improve the threading efficiency, the applicant previously designed a patent for a threading mechanism with publication number CN112353088. The structure is horizontally arranged. After the wire conveying mechanism conveys the preliminary material wire forward, the wire cutting mechanism cuts the preliminary material wire to obtain a predetermined length of the cut material wire. Then the wire conveying mechanism continues to convey the cut material wire to the wire hole of the brush disc, so that the two ends of the cut material wire are located on both sides of the brush disc. However, the threading mechanism has some disadvantages.

[0004] The wire conveying mechanism and the wire cutting mechanism in the entire threading mechanism are horizontally arranged, which requires a large layout space.

[0005] When the wire cutting mechanism cuts and forms the cut material wire, the cut material wire is actually no longer connected to the preliminary material wire. When the preliminary material wire continues to press and force the cut material wire into the wire hole, the preliminary material wire is easily misaligned with the cut material wire due to the elasticity of the material wire, which affects the threading quality and efficiency.

Each working mechanism on the threading mechanism is arranged longitudinally on the rack, which saves the volume and space occupied by the threading mechanism. Meanwhile, the wire conveying mechanism, the wire clamping mechanism and the wire cutting mechanism cooperate to cut the material wire of a predetermined length after the preliminary material wire is pulled into position, without the need to press the cut material wire by the preliminary material wire, thereby avoiding the misalignment between the preliminary material wire and the cut material wire during threading, which affects the threading efficiency in the wire hole.

The extension portion and the wire clamping portion form a strip-shaped groove 393 for accommodating the traction section 71 and extending longitudinally. The traction section 71 is kept stable in the strip-shaped groove 393 when clamped by the wire clamping assembly.

[0069] Further, the wire clamping rod and the extension portion are arranged on the same side. In order to avoid interference between the wire clamping rod and the extension portion, the extension portion is provided with a through groove matched with the wire clamping rod, and the wire clamping rod is inserted into the through groove. When the piston rod of the clamping cylinder 393 extends, the wire clamping block is away from the wire clamping rod, the head of the wire clamping rod is retracted into the through groove, and the traction section 71 enters the strip-shaped groove 393. When the piston rod of the clamping cylinder 393 is retracted, the wire clamping block is close to the wire clamping rod, the head of the wire clamping rod is inserted into the limiting groove, and the traction section 71 in the strip-shaped groove 393 is clamped. This design ensures that the wire clamping block with the extension portion does not interfere with the wire clamping rod and can normally cooperate with the wire clamping portion.

[0070] Furthermore, after the cut wire 8 is inserted into the wire hole 91, the brush plate 2 divides the cut wire 8 into two strands located on both sides of the brush plate 9. To fold the two strands outward, the frame 3 is provided with a wire folding mechanism 37. The wire folding mechanism 37 includes a wire folding frame 371 and a drive assembly for driving the wire folding frame 371 to move horizontally. The head of the wire folding frame 371 is the wire folding end, and the wire folding end has a strip groove 375 extending inward to the inside of the wire folding frame 371. The strip groove 375 divides the wire folding end into an upper wire folding part 375a and a lower wire folding part 375b. The wire folding frame 371 has a... The folding cavity extends vertically; the brush plate 9 is inserted into the strip groove 375, and the corresponding wire hole 91 on the brush plate 9 is located in the folding cavity; when the cut wire 8 is inserted into the wire hole 91, the cut wire 8 is divided into two strands of wire located on both sides of the brush plate 9. At this time, the wire clamping mechanism 39 releases the traction section 71, and the drive component drives the folding frame 371 to move away from the brush plate 9, so that the upper folding part 375a and the lower folding part 375b overlap the two strands of wire outward into a wire bundle; the folding mechanism 37 makes the two strands of wire quickly overlap into a wire bundle, improving the folding efficiency.

[0071] Furthermore, such as Figure 1 As shown, a guide assembly is provided inside the folding cavity. The guide assembly includes two opposing guide plates 372, one of which is connected to a guide cylinder 374. When the wire conveying mechanism 33 transports the prepared wire 7 downward, the piston rod of the guide cylinder 374 extends, causing the two guide plates 372 to come close together and form a guide groove 373 for guiding the prepared wire 7 into the wire hole 91. When the folding frame 371 moves away from the brush plate 9, the piston rod of the guide cylinder 374 retracts, causing the two guide plates 372 to move away from each other to avoid the outwardly overlapping stranded wires. In this embodiment, the guide assembly, while guiding the wire into the wire hole, also considers the problem of the guide plate avoiding the stranded wires during folding. Thus, the guide cylinder 374 controls the movement of one of the guide plates 372, effectively preventing the two stranded wires from interfering with the guide plate 372 when folding.

[0072] Furthermore, when the guide assembly is set in the wire folding cavity, the guide plate 372 is prone to interference with the brush plate 9. Therefore, in this embodiment, both guide plates 372 are provided with avoidance grooves (not shown) that correspond to the strip grooves 375 and are used to avoid the brush plate 9. The avoidance grooves divide the entire guide plate 372 into two guide support plates. The avoidance grooves can prevent the guide plate 372 from interfering with the brush plate inserted into the strip grooves 375, so that the wire folding work can proceed smoothly.

[0073] Furthermore, such as Figure 10To ensure that the brush disc 9 can rotate in the circumferential direction of its own axis and to press and fix the wire bundle after folding, the brush disc 9 is arranged on a wire pressing assembly. A plurality of wire holes 91 on the end face of the brush disc 9 form a closing area. The wire pressing assembly includes a support shaft 636 that can rotate in the circumferential direction. The top end of the support shaft 636 is provided with two wire pressing discs that are closed on the upper and lower sides of the brush disc 9 and are located in the closing area. The outer periphery of the wire pressing disc and the outer periphery of the lower wire pressing disc 638 are uniformly distributed with radial sliding grooves 631b corresponding to the wire holes 91. The radial sliding grooves 631b are slidably connected with radial pressing rods 633. The end face of the wire pressing disc away from the brush disc 9 is uniformly distributed with a plurality of radial guide grooves 632 connected with the radial sliding grooves 631b in the circumferential direction. The radial pressing rods 633 are provided with protruding portions 634 that extend beyond the end face of the wire pressing disc away from the brush disc 9 and are slidably connected in the radial guide grooves 632. The brush disc 9 divides the two wire pressing discs into an upper wire pressing disc 631 and a lower wire pressing disc 638. The frame 3 is also provided with an upper pull rod 341 and a lower pull rod 351 located on the upper and lower sides of the brush disc 9. The upper pull rod 341 and the lower pull rod 351 are respectively driven by an upper pull cylinder 342 and a lower pull cylinder 353. The upper pull rod 341 and the upper pull cylinder 342 constitute an upper pull assembly 34. The lower pull rod 351 and the lower pull cylinder 353 constitute a lower pull assembly 35. The upper pull rod 341 is located on the inner side of the protruding portion 634 of the upper wire pressing disc 631. The lower pull rod 351 is located on the inner side of the protruding portion 634 of the lower wire pressing disc 638. When the wire folding frame 371 folds two stock wires into a wire bundle, the upper pull cylinder 342 and the lower pull cylinder 353 respectively drive the upper pull rod 341 and the lower pull rod 351 to move away from the brush disc 9 and act on the corresponding protruding portion 634, so that the corresponding radial pressing rod 633 extends and presses the two stock wires on the corresponding end face of the brush disc 9. The formed wire bundle is kept fixed and does not spread outward, so as to be fixed.

[0074] Further, as Figure 7As shown, the structure of the folding mechanism 37 is as follows: the folding mechanism 37 is provided with a linkage assembly, which includes a first support plate 374a and a second support plate 374b away from a folding frame 371 in sequence, and a first cross rod 377 connected between the first support plate 374a and the second support plate 374b, and the folding frame 371 is arranged on the first support plate 374a; the driving assembly includes a first driving cylinder 376 and a second driving cylinder 379 acting on the second support plate 374b, the piston rod of the first driving cylinder 376 is telescopic and drives the folding frame 371 to move away from the radial direction of the brush disc 9 to leave space for the radial pressing rod 633 to extend radially; after the radial pressing rod 633 extends and presses the split material filaments, the piston rod of the second driving cylinder 379 is telescopic and drives the folding frame 371 to continue to move away from the brush disc 9, so that the folding frame 371 is completely separated from the filament bundle; the first driving cylinder 376 and the second driving cylinder 379 can form step-by-step driving on the second support plate 374b to make up for the response time difference of the driving assembly and the upper push-pull cylinder 342 and the lower push-pull cylinder 353, so that the piston rod of the first driving cylinder 376 is telescopic and leaves space for the corresponding radial pressing rod 633, and at the same time, the two split material filaments are still clamped in the strip-shaped groove 375 and do not spread outward, and after the radial pressing rod 633 presses the split material filaments, the piston rod of the second driving cylinder 376 is telescopic and completely separates from the formed filament bundle, so that the folding mechanism 37 can smoothly press the filament bundle after folding.

[0075] Further, since the filament hole 91 of the brush disc 9 is close to the outer peripheral edge of the brush disc 9, so that the two split material filaments are folded to form a filament bundle exceeding the outer periphery of the brush disc, and after the filament bundle is formed, the length of the split material filaments attached to the end face of the brush disc 9 is smaller than the length of the split material filaments exceeding the brush disc 9, therefore, corresponding to the two lengths, the telescopic stroke of the piston rod of the first driving cylinder 376 is smaller than that of the piston rod of the second driving cylinder 379, which is specifically manifested as: when the piston rod of the first driving cylinder 376 is telescopic and drives the folding frame 371 to move away from the radial direction of the brush disc 9 and leaves space for the radial pressing rod 633 to extend radially, the folding end only needs to just leave the end face of the brush disc 9, so the active range of the folding frame 371 at this time is relatively short; then the folding frame 371 needs to completely separate from the filament bundle, and the required active range is relatively long, so the telescopic length of the piston rod of the second driving cylinder 379 is relatively long.

[0076] Further, if the first driving cylinder 376 and the second driving cylinder 379 are arranged side by side to drive the folding frame 371 step by step, the piston rod of one cylinder will certainly move when the other cylinder is extended or retracted, which will affect the smoothness of the folding frame 371. Therefore, in order to meet the purpose of driving the folding frame 371 step by step, the first driving cylinder 376 is arranged on the first support plate 374a, the second driving cylinder 379 is arranged on the first vertical plate 378 close to the first support plate 374a, and the piston rod of the first driving cylinder 376 and the piston rod of the second driving cylinder 379 are opposite and connected together. Specifically, the piston rod of the first driving cylinder 376 and the piston rod of the second driving cylinder 379 have a shaft sleeve therebetween, and are inserted into the shaft sleeve and locked by screws. Thus, the space for arranging the driving assembly is saved while meeting the step-by-step driving of the folding frame 374.

[0077] Further, as shown in Figure 15 At the outer peripheral position of the pressing disc, a limiting portion 631a is formed between every two adjacent radial sliding grooves 631b, and the movable pressing rod 633 has two opposite side extension portions 633a on both sides. When the movable pressing rod 633 is retracted, the two side extension portions 633a abut against the corresponding limiting portion 631a, preventing the entire movable pressing rod 633a from being completely retracted into the radial sliding groove 631b.

[0078] Further, the bottom end of the movable pressing rod 633 has a limiting groove 635. After the movable pressing rod 633 is extended, the divided stock yarn is limited in the limiting groove 635, preventing the divided stock yarn from spreading to both sides.

[0079] Further, a plurality of weight-reducing grooves 631c are arranged through and uniformly distributed in the circumferential direction on the end face of the pressing disc, so as to lighten the structure of the entire pressing disc 631.

[0080] Further, as shown in Figure 2As shown, the upper push-pull assembly 34 is specifically structured as follows: the support frame 3 is provided with a horizontal plate 343 for mounting the upper push-pull assembly 34, and the horizontal plate 343 is provided with a relief hole 344 for avoiding the guide pipe 324; the upper push-pull assembly 34 comprises a first vertical plate 346 arranged on the support frame 3, an upper driving member in the form of an upper push-pull cylinder 342 connected to the first vertical plate 346, and a push-pull rod 341 connected to the piston rod of the upper push-pull cylinder 342; in order to ensure smooth movement of the push-pull rod 341, the first vertical plate 346 is provided with a connecting plate 345 for mounting the push-pull rod 341, and a second guide assembly is arranged between the connecting plate 345 and the first vertical plate 346; the second guide assembly comprises a second horizontal rod 344, and the connecting plate 345 is provided with a second guide hole matched with the second horizontal rod 344; the second guide holes are symmetrically arranged on the connecting plate 345, and the number and position of the second horizontal rod 344 and the second guide holes are matched; one end of the second horizontal rod 344 acts on the push-pull rod 341, and the other end penetrates into the second guide hole, thereby guiding the movement of the push-pull rod 341.

[0081] Further, as shown in Figure 8 the lower push-pull assembly 35 is specifically structured as follows: the lower push-pull assembly 35 comprises two mounting plates 352 arranged at intervals on the support frame 3, and a third horizontal rod 355 connected between the two mounting plates 352; a lower push-pull rod 351 is mounted on the mounting plate 352 close to the wire folding frame 371, and a second driving member in the form of a lower push-pull cylinder 353 acts on the mounting plate 352 away from the wire folding frame 371; in order to ensure smooth movement of the lower push-pull rod 351, the support frame 3 is provided with a second vertical plate 354 for mounting the lower push-pull cylinder 353, and the second vertical plate 354 is provided with a third guide hole for sliding cooperation with the third horizontal rod 355; the third guide holes are symmetrically arranged on the second vertical plate 354, and the number and position of the third horizontal rod 355 and the third guide holes are matched; the third horizontal rod 355 guides the movement of the lower push-pull rod 351.

[0082] Further, the wire holes 91 on the brush disc 9 that are not threaded are divided into wire feeding holes, and the wire holes 91 with wire bundles are divided into threaded holes; as shown in Figures 11-13To ensure that the yarn in the yarn hole will not be forked back to the yarn hole due to its own elasticity, the yarn penetrating mechanism further comprises a yarn pushing mechanism 38 arranged on the frame 3. The yarn pushing mechanism 38 is arranged at the side of the yarn clamping seat 396 in the yarn clamping mechanism 39, and the yarn pushing mechanism 38 can move synchronously with the yarn clamping mechanism 39 to approach or move away from the lower end of the brush disc 9. The yarn pushing mechanism 38 comprises a movable pushing rod 381 extending in the longitudinal direction and a rotating shaft 382. The rotating shaft 382 is connected with a pushing driving element, and the rotating shaft 382 is connected with the movable pushing rod 381 through a linkage rod 383. The pushing driving element can drive the rotating shaft 382 to rotate, and the linkage rod 383 moves to the adjacent yarn hole and the yarn hole on the brush disc 9, so as to push the yarn in the yarn hole to one side of the yarn hole. The next yarn hole can smoothly perform the yarn penetrating and folding, and the formed yarn is prevented from being rolled into the next formed yarn.

[0083] Further, the specific structure of the yarn pushing mechanism 38 is as follows: the pushing driving element can be directly connected with the rotating shaft 1 to drive the movable pushing rod 381 to move, or the pushing driving element is indirectly connected with the rotating shaft 1 through a transmission assembly. In the embodiment, the rotating shaft 382 is arranged on a pushing seat 386, and the pushing seat 386 is provided with a transmission assembly. The transmission assembly comprises a transmission rod 388 slidingly connected on the pushing seat 386. The transmission rod 388 is provided with a plurality of tooth grooves 389. The shaft body of the rotating shaft 1 is fixedly connected with a swing tooth element 387. The swing tooth element 387 has a plurality of tooth portions 387a matched with the tooth grooves 389. The driving element is a pushing cylinder 384. The piston rod of the pushing cylinder 384 is indirectly connected with the transmission rod 388 through a transition connecting plate 385. The piston rod of the pushing cylinder 384 is retracted or extended to drive the transmission rod 388 to slide on the pushing seat 386, so that the tooth grooves 389 are matched with the tooth portions 387a to drive the rotating shaft 1 to rotate.

[0084] Further, compared with the standard tooth-shaped groove arranged on the rod body of the transmission rod 388, the transmission rod 388 in the embodiment has lower cost and is more convenient to process, that is, the transmission rod 388 is a screw rod, and the tooth groove 389 is a spiral groove arranged on the screw rod. Compared with the standard tooth-shaped groove arranged on the transmission rod 388, the screw rod with the spiral groove has lower cost, and the meshing effect of the tooth groove 389 and the tooth portion 387a can be ensured.

[0085] Further, the volume of the wire poking mechanism 38 needs to be miniaturized, and the miniaturized wire poking mechanism 38 is easier to be installed to the corresponding position of the wire threading mechanism, so a containing cavity 3861 is arranged on the wire poking seat 386 in the embodiment, the rotating shaft 1 has a matching part penetrating in the containing cavity 3861, the matching part is fixedly connected with the swing tooth piece 387, a sliding guide hole 3862 communicating with the outside is arranged on the side wall of the containing cavity 3861, and the transmission rod 388 is slidingly connected in the sliding guide hole 3862; the containing cavity 3861 can contain the transmission assembly in the wire poking seat 386, reduce the space occupied by the transmission assembly in the wire poking mechanism, optimize the structural layout of the wire poking mechanism, and facilitate the installation of the wire poking mechanism to the wire threading mechanism to perform the wire poking work.

[0086] Further, the connecting relationship among the transition connecting plate 385, the transmission rod 388 and the wire poking cylinder 384 is as follows: the transition connecting plate 385 is provided with a connecting sleeve penetrating in the sliding guide hole 3862, the end of the transmission rod 388 is provided with a screw hole corresponding to the position of the connecting sleeve, a screw penetrates through the connecting sleeve and is screwed into the screw hole, so that the transmission rod 388 is connected with the transition connecting plate 385; the piston rod of the wire poking cylinder 384 is connected with a threaded rod, the transition connecting plate 385 is connected with an internal thread sleeve corresponding to the threaded rod, and the threaded rod is locked by the nut after being matched with the internal thread sleeve, so that the piston rod is connected with the transition connecting plate 385.

[0087] Further, when the wire is threaded and folded in the plurality of material wire holes one by one, only the adjacent wire bundle at the wire-threaded hole needs to be poked by the movable poking rod 381, but when the wire is threaded and folded in the last material wire hole, the wire holes on both sides of the last material wire hole have been threaded and formed into wire bundles, so another poking rod needs to be matched with the movable poking rod 381; as shown in the figure, the wire poking mechanism 38 in the embodiment further comprises a fixed poking rod 38a adjacent to the movable poking rod 381; when the support shaft 636 rotates and the last material wire hole on the brush disc 9 is threaded, wire bundles are formed in the two wire-threaded holes adjacent to the material wire hole, the wire poking drive member drives the rotating shaft 382 to rotate, so that the movable poking rod 381 moves to between one of the wire-threaded holes and the material wire hole, and pokes the wire bundle on one side of the wire-threaded hole, at this time, the fixed poking rod 38a is between the other wire-threaded hole and the material wire hole, and pokes the wire bundle on one side of the other wire-threaded hole. Figure 14

[0088] Based on the wire threading mechanism, the embodiment provides a wire threading method, which comprises the following steps:

[0089] S1: the wire conveying mechanism 33 downwardly conveys the prepared material wire 7, and makes the lower end of the prepared material wire 7 penetrate through one of the wire holes 91 of the brush disc 9 to form a traction section 71 beyond the lower end surface of the brush disc 9;

[0090] ​S2: The wire clamping mechanism 39 clamps the traction section 71 and is driven downward by the driving member to pull the prepared material wire 7 downward to a predetermined position;

[0091] S3: The wire cutting mechanism 36 cuts the prepared material wire 7, and the cut material wire 8 of a predetermined length is arranged in place in the wire hole 91;

[0092] S4: The brush disc 9 is rotated and the next wire hole 91 on the brush disc 9 is aligned with the prepared material wire 7;

[0093] S5: Steps S1-S4 are repeated in sequence until all the wire holes 91 on the brush disc 9 are completed. Through this wire threading method, each wire hole 91 on the brush disc 9 is threaded one by one, improving the quality and efficiency of wire threading, and facilitating efficient wire threading of multiple brush discs 9 one by one on the wire threading mechanism.

[0094] The above describes the present application and its embodiments in a schematic manner, which is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto.

A threader according to claim 6, wherein: The linkage assembly comprises a first supporting plate (374a) and a second supporting plate (374b) which are sequentially away from the wire folding frame (371), and a first cross rod (377) is connected between the first supporting plate (374a) and the second supporting plate (374b), and the wire folding frame (371) is arranged on the first supporting plate (374a); the driving assembly comprises a first driving cylinder (376) and a second driving cylinder (379) which act on the second supporting plate (374b), and a piston rod of the first driving cylinder (376) is telescopic and drives the wire folding frame (371) to move in a radial direction away from the brush disc (9) to leave a space for the radial pressing rod (633) to extend in the radial direction; after the radial pressing rod (633) extends and presses the separated material wire, the piston rod of the second driving cylinder (379) is telescopic and drives the wire folding frame (371) to continue to move in a direction away from the brush disc (9), so that the wire folding frame (371) is completely separated from the wire bundle.

8. A threader as defined in claim 1, wherein: The wire holes (91) on the brush disc (9) which are not threaded with the material wire are divided into material wire holes to be filled, and the wire holes (91) on the brush disc (9) which are threaded with the wire bundle are divided into material wire holes which are already filled; the wire pushing mechanism (38) is arranged on the rack (3), and the wire pushing mechanism (38) comprises a movable pushing rod (381) and a rotating shaft (382) which extend in the longitudinal direction, the rotating shaft (382) is connected with a wire pushing driving element, and the rotating shaft (382) is connected with the movable pushing rod (381) through a linkage rod (383); the wire pushing driving element can drive the rotating shaft (382) to rotate and drive the movable pushing rod (381) to move to between the adjacent material wire hole to be filled and the material wire hole which is already filled on the brush disc (9) to push the wire bundle in the material wire hole which is already filled to one side of the material wire hole which is already filled.

9. A threader according to claim 8, wherein: The wire pushing mechanism further comprises a fixed pushing rod (38a) which is adjacent to the movable pushing rod (381); when the supporting shaft (636) rotates and makes the last material wire hole to be filled on the brush disc (9) to be threaded with the material wire, the wire bundle is formed in the two material wire holes which are already filled which are adjacent to the material wire hole to be filled, the wire pushing driving element drives the rotating shaft (382) to rotate, the movable pushing rod (381) moves to between one of the material wire holes which are already filled and the material wire hole to be filled, and the wire bundle on one side of the one of the material wire holes which are already filled is pushed, at this time, the fixed pushing rod (38a) is between the other material wire hole which is already filled and the material wire hole to be filled, and the wire bundle on one side of the other material wire hole which is already filled is pushed.

10. A method of threading a filament based on the threading mechanism of claim 1, characterized in that: The following steps are included: S1: the wire conveying mechanism (33) conveys the prepared material wire (7) downward, and the lower end of the prepared material wire (7) passes through one of the wire holes (91) of the brush disc (9) to form a traction section (71) which exceeds the lower end surface of the brush disc (9); S2: the wire clamping mechanism (39) clamps the traction section (71), and the driving element drives the wire clamping mechanism (39) to move downward to pull the prepared material wire (7) downward to a predetermined position; S3: the wire cutting mechanism (36) cuts the prepared material wire (7) to make the cut material wire (8) of a predetermined length to be threaded in the wire hole (91); S4: the brush disc (9) is rotated and the next wire hole (91) on the brush disc (9) is aligned with the prepared material wire (7); S5: steps S1-S4 are repeated in sequence until all the wire holes (91) on the brush disc (9) are completed to be threaded with the material wire.
