Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically, to an adjustment device for changing the final coil direction of a drawing frame. Background Technology

[0002] Currently, rotor spinning mills use slivers produced by the first drawing pass directly for rotor spinning machine production in order to shorten the spinning process. However, due to the unique fiber opening and impurity removal mechanism of the rotor spinning machine, it cannot achieve the desired effect in opening and removing impurities from the fibers in the sliver produced by the first drawing pass.

[0003] When the sliver drawing machine starts drawing new slivers, it is easy to lose control. The slivers between the bottom cover of the sliver drawer and the sliver drawing disc cannot be effectively controlled due to space constraints. This causes the slivers at the bottom of the sliver drawer to become disordered, which affects the normal use of subsequent processes. Therefore, it is necessary to adjust the feeding direction of the cooked slivers. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown, this utility model provides an adjustment device for changing the final coil direction of a drawing frame, comprising: a support frame 2, on which a lifting frame 3 is slidably connected; a lifting arm 4, which is installed below the lifting frame 3, and includes a connecting rod 401, a pneumatic sleeve rod 403, and a telescopic claw 404. A top head 402 is fixedly installed at the bottom of the connecting rod 401, and the pneumatic sleeve rod 403 and the telescopic claw 404 are sleeved on the outside of the connecting rod 401. The pneumatic sleeve rod 403 is located above the telescopic claw 404, and the connecting rod 401 is fixedly connected below the lifting frame 3; and a flipping assembly, which is movably installed on the support frame 2, and includes a flipping shaft 6, a turntable 9, and a clamping fork. The flipping shaft 6 is connected to the output end of a rotary motor 7, and the rotary motor 7 is connected to the output end of a telescopic motor 8. The telescopic motor 8 is fixedly installed on the support frame 2, and the other end of the flipping shaft 6 is connected to the turntable 9. A clamping fork is movably installed on the turntable 9, and the movement of the clamping fork achieves clamping of the sliver and the tray 5.

[0022] A perforation is provided in the center of the tray 5, and the lifting arm 4 passes through the strip and the tray 5. The lifting arm 4 is used to pick up or release the tray 5 and the strip on it to prevent the strip from being damaged. The flipping component is used to clamp the strip and the tray 5 and flip the strip 180° so that the bottom and top of the strip are interchanged, thereby changing the feeding direction of the strip.

[0023] The telescopic claw 404 includes a top plate 4042, a bottom plate 4043, and an elastic steel sheet 4041. The elastic steel sheet 4041 is fixedly installed between the top plate 4042 and the bottom plate 4043. A connecting rod 401 passes through the top plate 4042 and the bottom plate 4043. A through hole 4044 is provided at the center of the top plate 4042 and the bottom plate 4043. The size of the through hole 4044 is adapted to the connecting rod 401. The connecting rod 401 passes through the top plate 4042 and the bottom plate 4043 through the through hole 4044. A top head 402 is fixed at the bottom of the connecting rod 401. The diameter of the top head 402 is larger than the diameter of the through hole 4044, but smaller than the diameter of the hole in the center of the tray 5.

[0024] Both the top head 402 and the bottom plate 4043 are magnetic components. In this embodiment, the top head 402 and the bottom plate 4043 are magnets, and the tray 5 is a ferromagnet. In this embodiment, the tray 5 is made of iron. The top head 402 fixes the bottom plate 4043 by magnetic attraction. The top plate 4042 is slidably connected to the connecting rod 401. Both the top head 402 and the bottom plate 4043 have magnetic attraction to the tray 5, which facilitates fixing the tray 5.

[0025] The top of the support frame 2 is connected to the lifting frame 3 via a lifting motor. This structure can be replaced by existing technology as long as it can enable the lifting frame 3 to rise and fall on the support frame 2. A screw jack can be used, in which the motor drives the screw to rotate, causing the thread on the screw to interact with the nut. The nut is fixed on the lifting frame 3, thereby enabling the lifting frame 3 to move up and down. The side of the lifting frame 3 away from the support frame 2 is connected to the lifting arm 4. The rise or fall of the lifting frame 3 causes the lifting arm 4 to move up or down.

[0026] The connecting rod 401 is fixedly installed below the lifting frame 3, controlling the lifting motor so that the lifting frame 3 drives the lifting arm 4 to descend. The top head 402, telescopic claw 404, and pneumatic sleeve 403 pass through the strip and through the perforation to the tray 5 in sequence. The pneumatic sleeve 403 is adjusted so that it moves downward and squeezes the telescopic claw 404. The bottom plate 4043 of the telescopic claw 404 is fixed on the top head 402, and the top head 402 is fixed to the bottom of the connecting rod 401. At this time, the top plate 4042 of the telescopic claw 404 is subjected to force and slides downward along the connecting rod 401. The elastic steel sheet 4041 is squeezed and opens under the tray 5. The telescopic claw 404 supports the tray 5, and the distance between the top head 402 and the bottom plate 4043 and the tray 5 is reduced. The top head 402 and the bottom plate 4043 have a magnetic attraction to the tray 5, further stabilizing the state of the tray 5. The lifting motor is controlled to move the lifting frame 3 and the lifting arm 4 upwards, and the elastic steel sheet 4041 supports the pallet 5 and the strips above it, moving upwards and detaching from the strip drum.

[0027] The flipping component moves horizontally toward the strip and tray 5, clamps the tray 5 and the strip, and flips them 180°.

[0028] A slide rail 10 is provided on the side of the turntable 9 away from the flipping axis 6. In this embodiment, there are two slide rails 10. A clamping fork is slidably connected in the slide rail 10. The clamping fork includes a first clamping fork 11 and a second clamping fork 12. The first clamping fork 11 is located above the second clamping fork 12. The second clamping fork 12 is fixedly connected to the slide rail 10. The first clamping fork 11 is slidably connected to the slide rail 10. An electric telescopic rod 13 is installed between the first clamping fork 11 and the second clamping fork 12. The electric telescopic rod 13 can adjust the distance between the first clamping fork 11 and the second clamping fork 12, so as to better clamp and fix the strip and the tray 5.

[0029] Driven by the telescopic motor 8, the flipping shaft 6 can move horizontally. When it is necessary to clamp the strip and the tray 5, the telescopic motor 8 is controlled to move the flipping shaft 6 closer to the strip. The second clamping fork 12 is located below the tray 5. The electric telescopic rod 13 is adjusted to control the distance between the first clamping fork 11 and the second clamping fork 12, so that the first clamping fork 11 is located above the strip and applies force to the strip and the tray 5 to clamp and fix the strip and the tray 5, thus completing the clamping of the strip and the tray 5. At this time, the pneumatic sleeve 403 is controlled to move upward, releasing the pressure applied to the telescopic claw 404. The elastic steel sheet 4041 returns to its original shape under its own elastic force, releasing the supporting effect on the pallet 5. The lifting motor is controlled to drive the lifting frame 3 and the lifting arm 4 to move upward, so that the lifting arm 4 is away from the strip, making it easier for the strip to flip. The magnetic attraction force of the top head 402 and the bottom plate 4043 on the pallet 5 is less than the lifting force of the lifting frame 3, and also less than the clamping force of the first clamping fork 11 and the second clamping fork 12 on the strip and the pallet 5.

[0030] Under the action of the rotary motor 7, the flipping shaft 6 drives the turntable 9, the first clamping fork 11, the second clamping fork 12, as well as the strips and the tray 5 to flip 180°, so that the strips that were originally messy at the bottom of the strip drum are flipped to the top. This allows problems to be detected in time when the strips are being combined, and it is easier to intervene through operation to avoid losses.

[0031] The lifting arm 4 is used again to pass through the strip and the tray 5, and to squeeze the elastic steel sheet 4041, so that the elastic steel sheet 4041 is in an open state under the tray 5, supporting the tray 5 and the strip, and placing the flipped strip into the strip drum. The telescopic motor 8 drives the flipping shaft 6, the turntable 9 and the clamping fork to move horizontally away from the lifting arm 4, so as to avoid the flipping component affecting the strip placed by the lifting arm 4.

[0032] The support frame 2 is fixedly connected to the base 1 at the top, which can ensure the overall stability of the device.
