Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a roving machine winding mechanism. Background Art

[0002] Roving frames are spinning machines that turn fiber strips into roving. Roving frames are divided into wing-spindle roving frames and twist-twist roving frames according to the twisting mechanism. Wing-spindle roving frames continuously apply twist to the yarn strips by rotating the spindle wings to produce twisted roving. Twist-twist roving frames clamp and twist the yarn strips with a pair of twisting leather plates, forming a false twist with alternating positive and negative twists on the yarn strips to produce non-twist roving. Wing-spindle roving frames and twist-twist roving frames can be divided into first-pass, second-pass and single-pass roving frames. The feeding forms, roving packages and number of spindles of various roving frames are different, but the machine structure and function are roughly the same.

[0003] After searching, the Chinese patent with publication number CN206799826U discloses a roving machine winding mechanism, including a frame, a movable seat body driven by a cylinder to lift and lower is provided on the frame, a clamping block for clamping the bottom end of the yarn tube is provided on the movable seat body, and a vertically extending spindle wing driven by a motor to rotate is provided just above the movable seat body, and the spindle wing includes a spindle rod with a yarn guide path inside, and wing arms are symmetrically fixed on both sides of the spindle rod, wherein the wing arm on one side of the spindle rod is also provided with a yarn guide path inside and a pressure palm is provided at the bottom of the wing arm. The structure of the roving machine winding mechanism is simple.

[0004] However, in the above technical solution, the seat body is driven by a cylinder to move in the vertical direction to avoid damage and deflection caused by the rotation and lifting of the spindle wing, and the clamping block is pushed by a spring to clamp and fix the yarn bobbin. However, after the yarn bobbin is wound and lowered, the clamping block needs to be manually moved away from the yarn bobbin before it can be removed. If the clamping block only contacts the surface of the yarn bobbin, it is easy to disassemble and assemble, but its clamping and fixing effect will be reduced. If the clamping block is inserted into a groove on the yarn bobbin, additional disassembly steps are required to facilitate the disassembly and assembly of the yarn bobbin. Utility Model Content

[0005] The utility model aims to provide a roving machine winding mechanism in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is as follows: a roving machine winding mechanism comprises a frame, a bottom plate is arranged under the frame, a hydraulic cylinder is connected to the bottom plate, a support plate is connected to the piston rod of the hydraulic cylinder, a yarn tube is placed on the support plate, a fixing mechanism for limiting the movement of the yarn tube is arranged on the outer peripheral surface of the yarn tube, guide mechanisms for guiding the movement of the support plate are arranged on both sides of the fixing mechanism, and a cleaning mechanism for cleaning the surface of the yarn tube is arranged on the guide mechanism;

[0007] The fixing mechanism includes a clamping assembly and an expansion assembly.

The expansion assembly is arranged on the inner peripheral wall of the yarn tube to enhance the fixing effect of the clamping assembly on the yarn tube.

[0008] Preferably, the clamping assembly includes a clamping block, a moving rod, a first spring and a sliding plate. The yarn tube is slidably connected to a circular receiving groove opened on the support plate. A clamping groove for sliding connection with the clamping block is opened on the peripheral wall of the yarn tube. The moving rod is connected to the clamping block. The first spring is sleeved on the outer peripheral surface of the moving rod. The moving rod passes through a through hole opened on the outer wall of the receiving groove and is rotatably connected to the sliding plate. The sliding plate is slidably connected to the guide mechanism.

[0009] Preferably, the guide mechanism includes a guide rod, a limit block and a guide block, the guide rod is symmetrically connected to the hydraulic cylinder, the top of the guide rod is connected to the limit block, the guide rod is slidably connected to the limit block with a through hole, and the limit block is connected to the support plate.

[0010] Preferably, a through hole slidably connected to the guide rod is provided on the sliding plate, and a stopper fixed at the bottom of the guide rod is slidably connected to the sliding plate, and an upper surface of the stopper is slidably connected to the sliding plate.

[0011] Preferably, the expansion assembly includes an arc plate and a second spring, the second spring is circumferentially distributed on the inner wall of the accommodating groove, the second spring is connected to the symmetrically arranged arc plate, and the arc plate is slidably connected to the inner circumferential wall of the yarn tube.

[0015] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0016] When the yarn bobbin is replaced, it can be directly inserted into the accommodating groove. The first spring in the accommodating groove pushes the clamping block into the clamping groove at the bottom of the yarn bobbin to fix it. When the yarn bobbin is removed, the support plate is driven downward by the hydraulic cylinder, and the sliding plate contacts the block and is blocked, while the support plate continues to move so that the sliding plate can pull the moving rod to make the clamping block lose its clamping effect. The yarn bobbin can be directly taken out, eliminating the additional step of disassembling the yarn bobbin and saving the time required for yarn bobbin replacement.

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-Figure 4 As shown, a roving machine winding mechanism proposed by the utility model comprises a frame 1, a bottom plate 2 is arranged below the frame 1, a hydraulic cylinder 3 is connected to the bottom plate 2, a support plate 4 is connected to the piston rod of the hydraulic cylinder 3, a yarn tube 5 is placed on the support plate 4, a fixing mechanism for limiting the movement of the yarn tube 5 is arranged on the outer circumference of the yarn tube 5, guide mechanisms for guiding the movement of the support plate 4 are arranged on both sides of the fixing mechanism, and a cleaning mechanism for cleaning the surface of the yarn tube 5 is arranged on the guide mechanism;

[0024] The fixing mechanism includes a clamping assembly and an expansion assembly. The clamping assembly is arranged on the support plate 4 to clamp the outer peripheral wall of the yarn tube 5 to limit the movement of the yarn tube 5. The expansion assembly is arranged on the inner peripheral wall of the yarn tube 5 to enhance the fixing effect of the clamping assembly on the yarn tube 5. The clamping assemblies are symmetrically arranged on both sides of the yarn tube 5. When the yarn tube 5 is placed on the support plate 4, its outer surface contacts the clamping block 6 and pushes the clamping block 6 to move in the receiving groove 10. The first spring 8 rebounds and pushes the clamping block 6 to insert into the clamping groove 11 on the yarn tube 5 to limit the movement of the yarn tube 5. The expansion assembly contacts the inner wall of the yarn tube 5 through the arc plate 16, and the arc plate 16 is brought close to the inner wall of the yarn tube 5 through the second spring 17. The inner and outer walls of the yarn tube 5 are clamped by the clamping assembly and the expansion assembly to enhance the clamping effect of the clamping assembly.

[0025] The clamping assembly includes a clamping block 6, a moving rod 7, a first spring 8 and a sliding plate 9. The yarn drum 5 is slidably connected to the annular receiving groove 10 provided on the support plate 4. The peripheral wall of the yarn drum 5 is provided with a clamping groove 11 for sliding connection with the clamping block 6. The moving rod 7 is connected to the clamping block 6. The first spring 8 is sleeved on the outer peripheral surface of the moving rod 7. The moving rod 7 passes through the through hole provided on the outer wall of the receiving groove 10 and is rotatably connected to the sliding plate 9. The sliding plate 9 is slidably connected to the guide mechanism. The yarn drum 5 is inserted into the receiving groove 10 and contacts with the clamping block 6. The yarn drum 5 pushes the clamping block 6 and the moving rod 7 to move and compress the first spring 8. The first spring 8 is compressed and then rebounds to drive the clamping block 6 to enter the clamping groove 11 on the surface of the yarn drum 5 to limit the movement of the yarn drum 5 and prevent the yarn drum 5 from shaking due to winding.

[0026] The sliding plate 9 is provided with a through hole slidably connected to the guide rod 12. The sliding plate 9 is slidably connected to a stopper 15 fixed to the bottom of the guide rod 12. The upper surface of the stopper 15 is slidably connected to the sliding plate 9. After the sliding plate 9 contacts the stopper 15, the piston rod of the hydraulic cylinder 3 still contracts, and the movement of the sliding plate 9 is restricted, thereby pulling the moving rod 7 to move so that the clamping block 6 and the clamping groove 11 are away from each other.

[0027] In this embodiment, the yarn tube 5 can be quickly replaced. When the yarn tube 5 is replaced, it can be directly inserted into the accommodating groove 10. The first spring 8 in the accommodating groove 10 pushes the clamping block 6 into the clamping groove 11 at the bottom of the yarn tube 5 to fix it. When the yarn tube 5 is disassembled, the support plate 4 is driven by the hydraulic cylinder 3 to move downward, the sliding plate 9 contacts the stopper 15 and is blocked, and the support plate 4 continues to move so that the sliding plate 9 can pull the moving rod 7 to make the clamping block 6 lose the clamping effect. The yarn tube 5 can be directly taken out, eliminating the additional step of disassembling the yarn tube 5, and saving the time required for replacing the yarn tube 5.

[0028] Embodiment 2

[0029] like Figure 1-Figure 3 As shown, a roving machine winding mechanism proposed in this embodiment, compared with the first embodiment, in this embodiment, the guide mechanism includes a guide rod 12, a limit block 13 and a guide block 14, the guide rod 12 is symmetrically connected to the hydraulic cylinder 3, the top of the guide rod 12 is connected to the limit block 13, the guide rod 12 is slidably connected to the limit block 13 with a through hole, and the limit block 13 is connected to the support plate 4. The movement of the support plate 4 drives the guide block 14 to slide on the guide rod 12, and when the support plate 4 moves to the top, the guide blocks 14 on both sides of it contact the limit blocks 13 to limit the continued movement of the support plate 4.

[0030] The stroke of the guide rod 12 is smaller than the stroke of the piston rod of the hydraulic cylinder 3. The shorter stroke of the guide rod 12 allows the piston rod of the hydraulic cylinder 3 to continue to retract after the sliding plate 9 contacts the stopper 15, and the movement of the sliding plate 9 is restricted, thereby pulling the moving rod 7 and causing the clamping block 6 to move away from the clamping groove 11 and lose the clamping effect on the bobbin 5, making it easier for the staff to remove the bobbin 5.

[0031] Embodiment 3

[0032] like Figure 3 As shown, the present embodiment proposes a roving machine winding mechanism. Compared with the second embodiment, in the present embodiment, the expansion assembly includes an arc plate 16 and a second spring 17. The second spring 17 is circumferentially distributed on the inner wall of the receiving groove 10. The second spring 17 is connected to the symmetrically arranged arc plates 16. The arc plates 16 are slidably connected to the inner peripheral wall of the yarn tube 5. The inner peripheral wall of the yarn tube 5 contacts the arc plate 16 and the protective pad 18 on the arc plate 16, and the second spring 17 is compressed. Then the second spring 17 rebounds and pushes the two arc plates 16 to move in opposite directions to contact the yarn tube 5 to enhance the fixing effect of the clamping assembly on the yarn tube 5.

[0033] The outer peripheral wall of the arc plate 16 is connected with a protective pad 18. The protective pad 18 is made of rubber material and plays a buffering role when the yarn tube 5 contacts the arc plate 16 to prevent the yarn tube 5 from being damaged by scratches.

[0034] Embodiment 4

[0035] like Figure 4 As shown, a roving machine winding mechanism proposed in this embodiment, compared with the third embodiment, in this embodiment, the cleaning mechanism includes a connecting rod 19, a mounting plate 20 and a cleaning brush 21, the symmetrically arranged connecting rod 19 is connected to the surface of the limit block 13, the connecting rod 19 is connected to the outer peripheral wall of the arc-shaped mounting plate 20, and the inner peripheral wall of the mounting plate 20 is connected to the cleaning brush 21 slidably connected to the yarn tube 5. After being lifted by the piston rod of the hydraulic cylinder 3, the support plate 4 gradually approaches the frame 1, and the cleaning brush 21 on the mounting plate 20 contacts the yarn tube 5, and its surface is cleaned by sliding between the two, reducing the dust and debris that may be contaminated on the surface of the yarn tube 5.

[0036] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
