Technical Field
[0001] This utility model relates to the field of silk production technology, and in particular to a silk blank winding device. Background Technology
[0002] There are several common ways to store silk blanks, such as folded storage and rolled storage. For example, rolled storage involves manually or mechanically winding the silk blank onto a rotating shaft to achieve the winding process.
[0003] In the prior art, such as the silk blank winding device disclosed in CN219688848U, a frame is included, and a platform is arranged above the frame. A drive mechanism for driving the platform to rotate is fixedly installed in the frame. The platform is rotated by activating the drive mechanism through the control unit to adjust the winding angle of the blank, so as to keep the blank able to be wound smoothly and avoid wrinkles during the winding process.
[0004] In order to keep the silk flat when winding the silk blank, the tension of the silk blank is increased by the tensioning mechanism to ensure the tension of the silk blank. However, the tension will cause the silk blank to be tightly wound on the take-up roller, and the friction between the silk blank and the take-up roller will increase, making it difficult to remove the silk blank from the take-up roller.

[0009] The bottom of the arc-shaped groove and the arc-shaped plate are provided with a clamping structure, which is used to clamp the blank.
[0010] Furthermore, the clamping structure includes a triangular groove at the bottom of the arc-shaped groove and an inclined surface at the bottom of the arc-shaped plate. The rear wall of the triangular groove is a slope that slopes downward at the front end and is parallel to the inclined surface. The slope and the inclined surface are used to clamp the blank.
[0011] Furthermore, the control component includes a main plunger hole opened at the left end of the roller and a plurality of support plunger holes opened on the inner arc surface of the arc groove and connected to the main plunger hole. A plunger is slidably installed at the left end of the main plunger hole through a drive component, and a support plunger is slidably installed inside the support plunger hole. The rear ends of the plurality of support plungers are fixedly connected to the arc plate.
[0012] Furthermore, the drive assembly includes a circular hole at the left end of the roller, and a cone is slidably installed inside the circular hole. A plunger is fixedly connected to the right end of the cone. A retaining ring is fixedly provided on the inner wall of the front end of the circular hole.

[0015] The present invention proposes a silk blank winding device with the following advantages: by setting an arc groove, an arc plate, and a clamping structure, the cross-sectional area of the winding roller is reduced by the arc plate being fully retracted into the arc groove, creating a gap between the winding roller and the blank, making it easier to remove the blank. The arc plate moves backward so that the inclined surface is close to the slope to clamp the blank, making it easier to fix the silk blank on the winding roller and prevent slippage during winding. Pushing the left baffle forward moves the arc plate backward while limiting the blank, and pushing the left baffle backward moves the arc plate backward while releasing the restriction, making the operation simpler and more convenient.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-5 As an embodiment of the present utility model, a silk blank winding device is disclosed, including a frame 1 and a winding roller 3 is rotatably mounted on the inner side of the frame 1 via a rotating assembly 2. An arc-shaped groove 4 is provided on the outer wall of the winding roller 3, and the arc-shaped groove 4 is used to reduce the cross-sectional area of the winding roller 3.
[0024] An arc-shaped plate 6 is slidably installed inside the arc-shaped groove 4 via a control component 5, and the arc-shaped plate 6 is used to close the arc-shaped groove 4.
[0025] The bottom of the arc-shaped groove 4 and the arc-shaped plate 6 are provided with a clamping structure 7, and the clamping structure 7 is used to clamp the blank.
[0026] Before winding the billet, one end of the billet is inserted into the bottom of the arc groove 4 and below the arc plate 6. The arc plate 6 is moved backward by the control component 5 to close the arc groove 4 so that the winding roller 3 returns to a circle. At the same time, the arc plate 6 moves backward to drive the clamping structure 7 to close and clamp the billet.
[0027] After the billet is wound, the arc plate 6 is moved forward by the control component 5 to open the arc groove 4 and the clamping structure 7, thereby releasing the clamping of the billet. The arc plate 6 is moved forward to completely retract the arc groove 4, which reduces the cross-sectional area of the roller 3 and creates a gap between the roller 3 and the billet, making it easier to remove the billet.
[0028] Specifically, the clamping structure 7 includes a triangular groove 71 at the bottom of the arc groove 4 and an inclined surface 72 at the bottom of the arc plate 6. The rear wall of the triangular groove 71 is a slope 73 that slopes downward at the front end and is parallel to the inclined surface 72. The slope 72 and the inclined surface 72 are used to clamp the blank.
[0029] Before winding the billet, one end of the billet is inserted into the arc groove 4 and placed on the slope 73. The arc plate 6 is moved back so that the inclined surface 72 is close to the slope 73, and finally the billet is clamped between the slope 73 and the inclined surface 72.
[0030] Furthermore, the control component 5 includes a main plunger hole 51 opened at the left end of the roller 3 and a plurality of support plug holes 52 opened on the inner arc surface of the arc groove 4 and connected to the main plunger hole 51. A plunger 53 is slidably installed at the left end of the main plunger hole 51 through the drive component 8. Support plugs 54 are slidably installed inside the support plug holes 52, and the rear ends of the plurality of support plugs 54 are fixedly connected to the arc plate 6.
[0031] The piston 53 is controlled to move left and right by the drive component 8, and hydraulic oil is injected into or extracted from the main piston hole 51 and the support piston hole 52, so that the support piston 54 drives the arc plate 6 to move back and forth.
[0032] Furthermore, the drive assembly 8 includes a circular hole 81 opened at the left end of the roller 3, and a cone 82 is slidably installed inside the circular hole 81. A plunger 53 is fixedly connected to the right end of the cone 82. A retaining ring 83 is fixedly provided on the inner wall of the front end of the circular hole 81. An inner retaining ring 84 is fixedly provided on the inner wall of the support plug hole 52. A spring 85 is inserted into the inner wall of the support plug hole 52, and the spring 85 is clamped between the support plug 54 and the inner retaining ring 84.
[0033] By pressing the cone 82 to the right, the plunger 53 is moved to the right. After releasing the cone 82, the spring 85 pushes the plunger 53 to the left, causing it to move to the left. The retaining ring 83 prevents the cone 82 from disengaging.
[0034] It should be noted that a right baffle 9 is sleeved on the right end of the roller 3, a limiting groove 10 is opened on the top of the right baffle 9, and a push plate 11 is rotatably installed in the limiting groove 10. A threaded hole is opened on the side of the upright plate of the frame 1, and a screw 12 is threadedly connected in the threaded hole. The left end of the screw 12 is fixedly connected to the push plate 11. An mounting plate 13 is fixedly installed on the bottom plate of the frame 1, and a connecting rod 14 is rotatably installed on the left end face of the mounting plate 13. A left baffle 15 is fixedly connected to the upper end of the connecting rod 14, and the right end of the left baffle 15 abuts against the roller 3 and the cone 82. Two stop posts 16 located on both sides of the connecting rod 14 are fixedly installed on the left end face of the mounting plate 13.
[0035] Push the left baffle 15 forward until it is blocked by the front stop post 16. At the same time, the right end face of the left baffle 15 abuts against the winding roller 3. During the forward push, the left baffle 15 squeezes the cone surface of the cone 82 to move it to the right. The left and right ends of the blank are limited by the right baffle 9 and the left baffle 15. The screw 12 is rotated by the knob on the right end of the screw 12 to drive the push plate 11 to move left and right. The push plate 11 drives the right baffle 9 to move left and right through the limiting groove 10 to adapt to blanks of different widths. After the winding is completed, push the left baffle 15 backward until the connecting rod 14 is blocked by the rear stop post 16. Release the left baffle 15 from limiting the blank, and then pull out the rolled blank.
[0036] In some embodiments, the rotating assembly 2 includes a bearing seat 21 fixed to the outside of the upright plate of the frame 1, the right end of the roller 3 passes through the frame 1 and is installed in the bearing seat 21, a square hole is opened on the inner wall of the upright plate of the frame 1, and a motor 22 is fixedly installed in the square hole, and the output shaft of the motor 22 is connected to the right end of the roller 3.
[0037] The output shaft of motor 22 drives the roller 3 to rotate via a transmission assembly including a timing belt and a timing pulley.
[0038] Working method: Before winding, place one end of the billet on the slope 73, then push the left baffle 15 forward until the connecting rod 14 is blocked by the front stop 16. At the same time, the left baffle 15 presses the cone surface of the cone 82 to the right, causing the plunger 53 to move to the right. The plunger 53 moves to the right and squeezes the hydraulic oil in the support plug hole 52 into the main plunger hole 51, so that the support plug 54 drives the arc plate 6 to move backward to close the compensating arc groove 4. At the same time, the inclined surface 72 approaches the slope 73 and finally clamps the billet between the slope 73 and the inclined surface 72.
[0039] During unloading, push the left baffle 15 until the connecting rod 14 is blocked by the rear stop 16. The spring 85 pushes the plunger 53 to the left, causing the cone 82 to move to the left until it is blocked by the retaining ring 83. The leftward movement of the plunger 53 draws the hydraulic oil in the support plug hole 52 back to the main plunger hole 51, causing the support plug 54 to move the arc plate 6 forward and completely retract the arc groove 4. This reduces the cross-sectional area of the roller 3, creating a gap between the roller 3 and the blank, making it easier to remove the blank. At the same time, the inclined surface 72 moves away from the slope 73, releasing the clamping of the blank, making it easier to remove the blank and place one end of the blank on the slope 73 again.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
