Description

Technical Field

[0001] This utility model relates to the field of weaving equipment technology, and in particular to a flexible material feeding device for a fully automatic weaving machine. Background Technology

[0002] In the existing technology, the weaving equipment used to weave various mats, curtains and decorative fabrics mostly relies on manual addition of weaving materials during the weaving process. Although there are a few automatic feeding devices, the feeding is generally uneven, especially when weaving irregularly shaped materials. Multiple weaving threads can crowd into the feed, leading to blockages. This not only affects production efficiency but also results in uneven and rough woven products, thus affecting product quality.

[0003] Chinese Patent (Patent Application No. 201811416216.0) discloses an "Automatic Feeding Device for a Roller Shutter Weaving Machine," which includes a feeding bracket, a hooking device, and a roller feeding device. The feeding bracket has a vertical feeding trough, wider at the top and narrower at the bottom, with the bottom width only accommodating a single woven strip. A transverse chute is located at the bottom of the feeding trough. The hooking device includes a hook and a hooking drive device that drives the hook to reciprocate along the transverse chute. The roller feeding device is positioned corresponding to the transverse chute. The hook, driven by the hooking drive device, hooks the woven strip from the bottom of the feeding trough and moves it along the transverse chute to the roller feeding device, where it is then automatically fed. This invention's entire mechanism works in synergy and sequential coordination to ingeniously feed the woven strip, improving feeding accuracy, significantly saving manpower, automating feeding, and thus increasing feeding efficiency.

[0004] Another Chinese patent (patent application number 201721490885.3) discloses a "yarn guiding transmission device for a rope braiding machine," which includes a first yarn feeding shaft, a second yarn feeding shaft, a main drive wheel, and a feed plate mounted on the frame. The first yarn feeding shaft has a first fixed sleeve at its end, and a first connecting rod on the first fixed sleeve. The first connecting rod is hinged to one end of the drive arm, and the other end of the drive arm is hinged to the edge of the main drive wheel. The second yarn feeding shaft has a second fixed sleeve at its end, and a second connecting rod on the second fixed sleeve. The second connecting rod is hinged to one end of the driven arm, and the other end of the driven arm is hinged to the middle of the drive arm. Sliding plates are provided at both ends of the bottom of the feed plate, and a limiting groove is provided on the frame. This solution effectively reduces power consumption and makes the feeding transmission of the braiding machine smoother.

[0005] Another invention, disclosed in Chinese Patent No. 201110323260.9, is a "Manual Bamboo Fence Weaving Machine." It includes a frame, a weaving mechanism mounted on the frame, an arc-shaped sliding plate, a material feeding mechanism, and a wire turntable assembly. The weaving mechanism comprises at least three sets of parallel wire twisters. Each set consists of a base, a driving wire twisting shaft connected to the base, a driving gear and a double sprocket connected to the driving wire twisting shaft, a driven wire twisting shaft connected to the base, and a driven gear connected to the driven wire twisting shaft. The double sprockets on adjacent wire twisters are connected by a chain. Both the driving and driven wire twisting shafts have two axially oriented wire-passing grooves on their cylindrical surfaces, through which multiple galvanized iron wires pass. This invention has a simple structure and low manufacturing cost. Due to the use of mechanical transmission and twisting weaving, the woven bamboo fences are of consistent specifications and stable quality. Because it is manually driven, the weaving speed can be manually controlled, making it not only simple to operate but also safe and reliable, and with high production efficiency. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a feeding device that can safely push the incoming braiding yarn and is suitable for fully automatic braiding equipment.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a flexible material feeding device for a fully automatic knitting machine: it includes a frame plate 1, and a feeding groove 22, a feeding groove 17, and a mounting groove 12 are respectively provided in the upper middle, middle, and lower middle parts of the frame plate 1. The lower part of the feeding groove 22 is connected to the upper part of the feeding groove 17.

[0008] The rotating shaft mechanism includes a rotating shaft 42, a rotating shaft cylinder 43, a front rotating shaft bearing 39, and a rear rotating shaft bearing 41. The rotating shaft cylinder 43 is installed in the lower left part of the mounting groove 12 of the frame plate 1, and the front and rear ends of its inner hole are respectively installed with the front rotating shaft bearing 39 and the rear rotating shaft bearing 41. After the front and rear ends of the rotating shaft 42 pass through the front rotating shaft bearing 39 and the rear rotating shaft bearing 41, they are rotatably connected to the flexible feeding mechanism and the feeding drive mechanism, respectively.

[0009] The flexible feeding mechanism includes a flexible feeding drum 2, a flexible feeding drum bearing 28, a flexible feeding rod 5, and a flexible feeding assembly; the flexible feeding drum bearing 28 is installed in the inner hole of the flexible feeding drum 2 and is rotatably mounted on the front end of the rotating shaft 42; the flexible feeding rod 5 is located on the upper part of the outer cylindrical surface of the flexible feeding drum 2, and its upper end is connected to the lower part of the flexible feeding assembly.

[0010] The flexible feeding assembly includes a symmetrical front flexible feeding plate 19 and a rear flexible feeding plate 34, as well as an upper screw 25 and a lower screw 26; the front flexible feeding plate 19 is shaped as follows: The flexible feed bar 5 is clamped on the front and rear sides of the upper part of the flexible feed bar 5 and fixed by the upper screw 25 and the lower screw 26, respectively, and the "I"-shaped parts of the upper parts of the two extend to the front and rear sides of the frame plate 1 at the upper end of the feed trough 17.

[0011] On the upper left side of the front flexible material feeding plate 19 and the rear flexible material feeding plate 34, there are also front flexible material feeding sub-plates 18 and 35 facing forward and backward respectively.

[0012] The feeding drive mechanism includes a feeding drive drum 30, a feeding drive drum bearing 33, a feeding drive rod 13, and a positioning rod 14. The feeding drive drum bearing 33 is installed in the inner hole of the feeding drive drum 30 and is rotatably mounted on the rear end of the rotating shaft 42. The feeding drive rod 13 is located on the upper part of the outer cylindrical surface of the feeding drive drum 30, and the positioning rod 14 is arranged in the front-rear direction at its upper end. The front end of the positioning rod 14 passes through the mounting groove 12 and reaches the left side of the upper end of the flexible feeding rod 5.

[0013] The feeding power mechanism includes a feeding power rod 7, a feeding power rod pin 8, a feeding power rod connector 6, a feeding power cam connecting rod 4, a feeding power traction rod 9, and a feeding power traction spring 11. The right end of the feeding power rod 7 is connected to the left side of the outer cylindrical surface of the feeding drive drum 30. The front and rear ends of its left end are respectively fitted by the feeding power rod pin 8 through the lower end of the feeding power traction rod 9 and the upper end of the feeding power rod connector 6. The lower end of the feeding power rod connector 6 is connected to the upper end of the feeding power cam connecting rod 4. The left end of the feeding power traction spring 11 is hooked on the upper end of the feeding power traction rod 9, and its right end is hooked on the rear end of the upper screw 25 extending to the back of the frame plate 1.

[0014] A stop plate 15 is also provided in front of the frame plate 1 on the left side of the feed trough 17, and a forward-bent stop plate 16 is provided on the right side of the stop plate 15.

[0015] The flexible feeding device for the fully automatic braiding machine of this utility model adopts a spring-driven flexible feeding mechanism for rotating feeding. When the braiding yarn enters the upper end of the feeding trough from the feed trough and encounters jamming due to special circumstances, the flexible feeding mechanism will automatically stop rotating. Therefore, it not only avoids the braiding yarn from being broken, but also avoids damage to the flexible feeding mechanism and other adjacent supporting devices, thereby improving the safety of equipment operation.

[0035] The receiving robot (not shown in the figure) is installed in front of the frame plate 1 on the upper right side of the pushing and dispersing mechanism.

[0037] The rotating shaft 42 is a two-way double-step shaft, which is installed in the inner hole of the rotating shaft cylinder 43, and its front and rear ends protrude from the front and rear ends of the rotating shaft cylinder 43.

[0038] The front half of the rotating shaft cylinder 43 passes through the lower left part of the mounting groove 12 of the frame plate 1 from back to front and is fixed. A front bearing 39 and a rear bearing 41 are respectively installed at the front and rear ends of its inner hole (which is a through hole). The inner rings of these bearings abut against two steps in the middle of the rotating shaft 42, with the front bearing 39 positioned at the front of the frame plate 1. The front end of the front bearing 39 and the rear end of the rear bearing 41 in the inner hole of the rotating shaft cylinder 43 are respectively positioned by a front bearing retaining ring 38 and a rear bearing retaining ring 40. After the front and rear ends of the rotating shaft 42 pass through the front bearing 39 and the rear bearing 41, they are rotatably connected to the flexible feeding mechanism and the feeding drive mechanism, respectively.

[0039] Flexible material feeding mechanism (see attachment) Figure 1 , 2 As shown in Figure 3, it consists of a flexible feeding drum 2, a flexible feeding drum bearing 28, a flexible feeding rod 5, and a flexible feeding assembly.

[0040] The inner hole in the middle of the flexible material feeding rotary drum 2 is a stepped through-hole. The flexible material feeding rotary drum bearing 28 is installed in the inner hole of the flexible material feeding rotary drum 2, and a retaining ring 3 for the flexible material feeding rotary drum bearing hole is installed at the front end of the flexible material feeding rotary drum bearing 28 for positioning the outer ring of the flexible material feeding rotary drum bearing 28; the flexible material feeding rotary drum bearing 28 is sleeved on the front end of the rotating shaft 42, and a flexible material feeding rotary drum bearing end cover 29 is also installed on the front end face of the rotating shaft 42 for positioning the inner ring of the flexible material feeding rotary drum bearing 28.

[0041] The flexible material feeding rod 5 is arranged at the upper part of the outer cylindrical surface of the flexible material feeding rotary drum 2, and its upper end is connected to the lower part of the flexible material feeding assembly.

[0042] The flexible material feeding assembly is composed of a front flexible material feeding plate 19 and a rear flexible material feeding plate 34 which are roughly symmetrical, and an upper screw rod 25 and a lower screw rod 26.

[0043] The front flexible material feeding plate 19 is shaped like a certain shape. The "one" in the middle is the front flexible material feeding plate bent horizontal part 45, which is used to bend its upper part forward to the front of the pusher and material spreading mechanism front plate 21; the "one" in the middle of the rear flexible material feeding plate 34 is the rear flexible material feeding plate bent horizontal part 44, and its length is greater than that of the front flexible material feeding plate bent horizontal part 45. Similarly, it is used to bend its upper part backward and pass through the installation groove 12 to the rear side of the frame plate 1; the middle and lower parts of the front flexible material feeding plate 19 and the rear flexible material feeding plate 34 are respectively clamped on the front and rear sides of the upper part of the flexible material feeding rod 5 (after clamping, it is in a certain shape), and are fixed by the upper screw rod 25 (this screw rod extends backward and passes through the installation groove 12 to the rear side of the frame plate 1) and the lower screw rod 26. The "I" shaped part at the upper part of the front flexible material feeding plate 19 extends to the front of the middle and upper part of the pusher and material spreading mechanism front plate 21 and is slightly higher than the lower port of the material discharging groove 22; the "I" shaped part at the upper part of the rear flexible material feeding plate 34 extends to the rear side of the frame plate 1 at the upper end part of the feed groove 17 respectively, and is also slightly higher than the lower port of the material discharging groove 22.

[0044] At the left side of the upper ends of the front flexible material feeding plate 19 and the rear flexible material feeding plate 34, there are respectively provided front flexible material feeding auxiliary plates 18 and rear flexible material feeding auxiliary plates 35 which face forward and backward respectively, for increasing the material feeding area and reducing the damage to the braided material filaments during the material feeding process.

[0045] At the front of the frame plate 1 on the left side of the feed groove 17 (that is: the lower end of the material blocking mechanism front plate 20), a material stopping plate 15 is also provided, and a material stopping auxiliary plate 16 which bends forward is provided on the right side of the material stopping plate 15 (that is: the material stopping plate 15 and the material stopping auxiliary plate 16 are combined into one to form a "horizontally folded plate"), for stopping the braided material filaments that are fed in place by the flexible material feeding assembly.

[0046] The material feeding driving mechanism (see attachment Figure 1, 2 (As shown in Figure 3) It consists of a feeding drive drum 30, a feeding drive drum bearing 33, a feeding drive rod 13, and a positioning rod 14.

[0047] The inner hole of the feeding drive drum 30 is a stepped through hole. The feeding drive drum bearing 33 is installed in the inner hole of the feeding drive drum 30. A retaining ring 31 for the feeding drive drum bearing hole is also installed at the rear end of the feeding drive drum bearing 33 for positioning the outer ring of the feeding drive drum bearing 33. The feeding drive drum bearing 33 is mounted on the rear end of the rotating shaft 42. A feeding drive drum bearing end cap 32 is also installed on the rear end face of the rotating shaft 42 for positioning the inner ring of the feeding drive drum bearing 33.

[0048] The feeding drive rod 13 is located on the upper part of the outer cylindrical surface of the feeding drive drum 30. A positioning rod 14 is provided at its upper end in the front-back direction (the positioning rod 14 is used to prevent the flexible feeding mechanism, i.e., the flexible feeding rod 5, from excessive feeding, and also to push the flexible feeding rod 5 to return, i.e., to release feeding). The front end of the positioning rod 14 passes through the mounting groove 12 and reaches the left side of the upper end of the flexible feeding rod 5 (i.e., the middle left side of the front flexible feeding plate 19).

[0049] Material feeding power mechanism (see attachment) Figure 1 and 2 The device shown is composed of a feeding power rod 7, a feeding power rod pin 8, a feeding power rod connector 6, a feeding power cam connecting rod 4, a feeding power traction rod 9, and a feeding power traction spring 11.

[0050] The right end of the feeding power rod 7 is connected to the left side of the outer cylindrical surface of the feeding drive drum 30. The front and rear ends of its left end are respectively fitted with the lower end of the feeding power traction rod 9 and the upper end of the feeding power rod joint 6 (a fisheye joint, i.e., a self-lubricating rod end spherical bearing) by the feeding power rod pin 8. The lower end of the feeding power rod joint 6 is connected to the upper end of the feeding power cam connecting rod 4. The lower end of the feeding power cam connecting rod 4 is connected to the cam on the main shaft of the fully automatic braiding machine (not shown in the figure). The left end of the feeding power traction spring 11 is hooked on the feeding power traction spring hook rod 10 at the upper end of the feeding power traction rod 9, and its right end is hooked on the rear end of the upper screw 25 extending to the rear side of the frame plate 1.

[0051] The flexible material feeding device for the fully automatic braiding machine in this embodiment is used in conjunction with the fully automatic braiding machine.

[0052] In use, the ends of the braided yarns fall downward from the feed trough 22 of the frame plate 1 and accumulate in a narrow, elongated cavity that is wider at the top and narrower at the bottom. This cavity is formed by the right side of the blocking blade of the blocking mechanism front plate 20 and the blocking mechanism rear plate 37 and the sliding blade of the sliding mechanism front plate 23 and the sliding mechanism rear plate 36. At this time, the gap between the blocking blade formed by the right side of the blocking mechanism front plate 20 and the blocking mechanism rear plate 37 and the left side of the pushing and dispersing mechanism front plate 21 and the pushing and dispersing mechanism rear plate 24 is basically slightly larger than the thickness of a single braided yarn. However, since the braided yarn itself is not very thick, it usually accumulates. That is to say, in most cases, it is stacked by 2-3 or even more yarns, causing mutual crowding. This prevents the braided yarns from naturally passing down through the narrow cavity and entering the feed trough 17 at the lower end of the feed trough 22.

[0053] At this time, the cam mechanism on the main shaft of the fully automatic braiding machine pushes the material feeding and dispersing power mechanism 27, together with the front plate 21 and the rear plate 24 of the material feeding and dispersing mechanism, to move upward. The left side of the front plate 21 and the rear plate 24 of the material feeding and dispersing mechanism presses down on the braiding filaments on the one hand, and on the other hand, moves them to the upper left, forming a "rubbing" action. In this way, the multiple stacked braiding filaments are rubbed and dispersed to the upper left, so that they are arranged in a single strand, and then fall to the lower end of the feed trough 22. Then, the receiving robot catches and clamps the bottommost braiding filament, and then swings it to the middle of the feed trough 17 to the lower left, and then releases the clamp.

[0054] At this time, the cam mechanism on the main shaft of the fully automatic braiding machine moves the feeding power cam connecting rod 4, along with the feeding power rod joint 6 and the feeding power rod 7, downwards. This, in turn, causes the feeding drive drum 30, along with the feeding power rod 7 and the feeding power traction rod 9, to rotate counterclockwise around the rotating shaft 42 (see...). Figure 1 As shown, in Figure 2In the middle (which manifests as clockwise rotation), at this time, the material-pushing power traction spring 11 hooked on the upper end of the material-pushing power traction rod 9 and the material-pushing power traction spring hook rod 10 pulls the flexible material-pushing rod 5 and the flexible material-pushing assembly to rotate counterclockwise through the upper screw 25 hooked on the other end of the material-pushing power traction spring 11. The front flexible material-pushing sub-plate 18 and the rear flexible material-pushing sub-plate 35 on the front flexible material-pushing plate 19 and the rear flexible material-pushing plate 34 of the flexible material-pushing assembly then push the braided material threads on the receiving robot arm to the left. The material is fed to the left side of the feed trough 17, and the stop plate 15 and the stop plate 16 stop it from continuing to push to the left to avoid over-pushing. At the same time, the positioning rod 14 at the upper end of the feeding drive rod 13 also blocks the flexible feeding rod 5, together with the front flexible feeding plate 19 and the rear flexible feeding plate 34 above it, from continuing to push to the left, thereby further avoiding over-pushing. At this point, the feeding work is completed, and the braiding yarn that has been fed is then transported to the fully automatic braiding machine by the feeding device of the fully automatic braiding machine for weaving.

[0055] Next, the cam mechanism on the main shaft of the fully automatic knitting machine moves the feeding power cam connecting rod 4, along with the feeding power rod joint 6 and the feeding power rod 7, upwards. This, in turn, causes the feeding drive drum 30, along with the feeding power rod 7 and the feeding power traction rod 9, to rotate clockwise around the rotating shaft 42 (see...). Figure 1 As shown, in Figure 2 In the middle, it rotates counterclockwise. At this time, the positioning rod 14 at the upper end of the feeding drive rod 13 pushes the flexible feeding rod 5, together with its upper front flexible feeding plate 19 and rear flexible feeding plate 34, to swing to the right (see...). Figure 1 As shown, the flexible feeding drum 2, together with the flexible feeding rod 5 and its upper front flexible feeding plate 19 and rear flexible feeding plate 34, rotates clockwise around the rotating shaft 42 to its original position (at this time, the right side of the bent horizontal part 45 of the front flexible feeding plate and the bent horizontal part 44 of the rear flexible feeding plate respectively abuts against the left side of the front plate 21 of the material pushing and dispersing mechanism and the left side of the rear plate 24 of the material pushing and dispersing mechanism); then, the next feeding process is carried out.

[0056] During the material feeding process, when a special situation occurs, such as when the braided material gets stuck at the lower end of the feeding trough 22 or on the receiving robot arm, the braided material gets stuck on the upper left side of the front flexible feeding plate 19 and the rear flexible feeding plate 34 and cannot swing synchronously with the feeding drive rod 13. At this time, since the flexible feeding mechanism and the feeding drive mechanism are rotatably mounted at the front and rear ends of the rotating shaft 42, the flexible feeding rod 5 and the front flexible feeding plate 19 and the rear flexible feeding plate 34 above it will overcome the tension of the feeding power traction spring 11 and remain stationary, thereby preventing the braided material from being broken or further damaging the equipment. This is the key to flexible feeding.

[0057] The flexible material feeding device for the fully automatic weaving machine of this invention can be used in conjunction with the fully automatic weaving machine to weave various types of mats, curtains, and decorative fabrics.
