The device has the beneficial effect that the positions of the two baffles are adjusted more simply and conveniently.

Description

Technical Field

[0001] This utility model relates to a winding device, and more particularly to a baffle structure for a winding device. Background Technology

[0002] In the textile industry, winding devices are generally used to wind fabric onto a reel. A common winding device structure includes: a frame, two support rollers rotatably connected to the frame, two baffles, and a motor. A reel of matching length is selected based on the fabric width, and the reel is placed on the two support rollers. The two baffles can be adjusted axially along the support rollers, and their positions are adjusted according to the reel length. The fabric first passes between the two support rollers and then winds onto the reel. The motor is started, driving at least one support roller to rotate, causing the reel to rotate through friction, thus winding the fabric. During the winding process, the two baffles limit the axial displacement of the reel and restrict the edges of the fabric, ensuring that the fabric is wound relatively neatly onto the reel.

[0003] The existing baffle adjustment method is generally as follows: two guide rods are installed on the equipment frame, and two support rollers are positioned between the two guide rods; two slide bars are slidably connected to the two guide rods, and two baffles are fixedly connected to the two slide bars respectively; both ends of the slide bars have threaded through holes, and hand-tightening bolts are threaded into the threaded through holes. Tightening the hand-tightening bolts causes them to press against the guide rods, thereby fixing the slide bars to the guide rods. This adjustment method also has problems: it is relatively cumbersome to operate, especially when tightening the hand-tightening bolts on the rear side, which is very inconvenient due to the greater distance.

[0005] This application provides a baffle structure for a winding device, comprising:

[0006] The mounting strip is horizontal and has a first toothed rack.

[0007] The support bar is horizontal; the top surface is the support surface and has a strip-shaped through groove; a second toothed rack is also located below the support surface.

[0008] Both slide bars are longitudinal; a baffle is located in the middle; the first end of each slide bar is slidably connected to the first mounting bar.

[0009] Two first gears are rotatably connected to the first ends of two slide bars about a vertical axis; both mesh with the first rack.

[0010] Two sets of limiting components are respectively set at the second end of the two slide bars;

[0011] A set of limiting components includes:

[0012] a second shaft, rotatably connected to the slide bar about a vertical axis;

[0013] a transmission pair, disposed between the second shaft and the first gear; the transmission pair is used to rotate the two in the same direction or in the opposite direction, and the numerical value of the angular velocity of rotation is the same;

[0014] a third shaft, telescopically connected to the second shaft and rotates with the second shaft; the bottom end penetrates the strip-shaped through slot;

[0015] a limiting block, connected to the third shaft; above the support surface;

[0016] a second gear, having the same number of teeth and modulus as the first gear; fixedly connected to the third shaft; below the support surface;

[0017] a spring, acting on the third shaft, so that the limiting block remains in contact with the support surface to keep the support slide bar in a state, and the second gear remains in a state of limiting the movement of the second rack to keep the second gear engaged with the second rack.

[0018] In some embodiments, the transmission pair includes two synchronous pulleys fixedly connected to the second shaft and the first gear respectively, and a synchronous belt tensioned between the two synchronous pulleys.

[0023] In summary, in the present application, a baffle structure of a winding device includes a mounting bar, a support bar, two slide bars, two first gears, and two sets of limiting members. The movement of the slide bar is limited by the interlocking of the two sets of gear and rack, so that the slide bar is stably maintained on the mounting bar and the support bar. When it is necessary to adjust the position of the slide bar, a person works on the third shaft to overcome the action of the spring on the third shaft, so that the third shaft moves upward, correspondingly, the limiting block moves away from the support surface, and the second gear disengages from the second rack. The interlocking of the two sets of gear and rack is also released, and the slide bar can be moved. In the moving process, the first gear rotates and also rotates the second gear through the transmission pair. Therefore, after the slide bar moves to the corresponding position, the third shaft is released, the second gear can restore engagement with the second rack, the two sets of gear and rack are interlocked again to limit the movement of the slide bar. The position of the two baffles is adjusted, and the operation is more simple and convenient. BRIEF DESCRIPTION OF DRAWINGS

[0038] Please refer to Figure 1 and Figure 2 A baffle structure of a winding device includes a mounting bar 1, a supporting bar 2, two sections of sliding bars 3, two first gears 4, and two sets of limiting members 5.

[0039] The mounting bar 1 is transverse, and is used to be fixedly connected to a mounting frame of the winding device. The mounting bar 1 further has a first rack 1a. Correspondingly, the first rack 1a is also transverse. Considering that the length of the winding shaft changes within a certain range, the first rack 1a can be divided into two sections, which are respectively located at the portions of the mounting bar 1 close to the two ends.

[0040] In some embodiments, the mounting bar 1 is rod-shaped, and the outer wall has a plurality of notches to form the first rack 1a.

[0041] The supporting bar 2 is transverse, and is also used to be fixedly connected to the mounting frame of the winding device. After the mounting bar 1 and the supporting bar 2 are fixedly connected to the mounting frame, two supporting rollers of the winding device are located between the mounting bar 1 and the supporting bar 2.

[0042] The top surface of the supporting bar 2 is a supporting surface, and the supporting surface further has a strip-shaped through groove 2a. The supporting bar 2 further has a second rack 2b at a position below the supporting surface. More specifically, the cross section of the supporting bar 2 can be rectangular, hollow inside, and the second rack 2b can be fixedly connected to a vertical inner wall of one side. Considering that the length of the winding shaft changes within a certain range, the strip-shaped through groove 2a can be divided into two sections, which are respectively located at the portions of the supporting surface close to the two ends; and the second rack 2b can be divided into two sections, which are respectively located at the portions of the supporting bar 2 close to the two ends.

[0043] Both of the two segments of the slide bar 3 are longitudinal. The first end of the slide bar 3 is slidingly connected to the first mounting bar 1, and more specifically, a slide sleeve 3a is fixedly connected to the slide bar 3, the slide sleeve 3a is sleeved on the first mounting bar 1, and the slide sleeve 3a has a notch corresponding to the position of the first rack 1a.

[0044] In combination with the above embodiment in which the mounting bar 1 is a rod, the mounting bar 1 also has a notch to form a limiting plane 1b, and the slide sleeve 3a is attached to the limiting plane 1b, thereby limiting the rotation of the slide sleeve 3a relative to the first mounting bar 1.

[0045] The middle position of the two segments of the slide bar 3 has a baffle 3b, that is, the position of the baffle 3b is adjusted by the sliding of the slide bar 3.

[0046] Please refer to Figure 3 and Figure 5 , the two first gears 4 are respectively rotatably connected to the first ends of the two slide bars 3 about vertical axes, that is, the first ends of the slide bars 3 are rotatably connected with the first shafts 4a on which the first gears 4 are fixedly connected. Both of the two first gears 4 are engaged with the first rack 1a. Correspondingly, if the first rack 1a is designed to be divided into two segments, the two first gears 4 are engaged with one segment respectively.

[0047] The two sets of limiting members 5 are respectively arranged at the second ends of the two slide bars 3. One set of limiting members 5 includes a second shaft 51, a transmission pair 52, a third shaft 53, a limiting block 54, a second gear 55, and a spring 56.

[0048] The second shaft 51 is rotatably connected to the slide bar 3 about a vertical axis.

[0049] The transmission pair 52 is arranged between the second shaft 51 and the first gear 4, that is, between the second shaft 51 and the first shaft 4a. The transmission pair 52 is used to make the two rotate in the same direction or in opposite directions, and the numerical value of the angular velocity of rotation is the same.

[0050] In some embodiments, the transmission pair 52 includes a connecting shaft and two sets of bevel gear pairs. The connecting shaft is rotatably connected to the slide bar 3 about a longitudinal axis, one set of bevel gear pairs is arranged between the connecting shaft and the first shaft 4a, and the other set of bevel gear pairs is arranged between the connecting shaft and the second shaft 51. Correspondingly, the second shaft 51 and the first gear 4 rotate in opposite directions.

[0051] In some embodiments, the transmission pair 52 includes two synchronous wheels 521 and a synchronous belt 522. The two synchronous wheels 521 are respectively fixedly connected to the second shaft 51 and the first gear 4, and the synchronous belt 522 is tensioned between the two synchronous wheels 521. Correspondingly, the second shaft 51 and the first gear 4 rotate in the same direction.

[0052] Compared with the connecting shaft and the two sets of bevel gear pairs, the two synchronous wheels 521 and the synchronous belt 522 are used as the transmission pair 52, and the limiting member 5 is more simple and convenient to assemble on the slide bar 3.

[0053] Please refer to Figure 1 and Figure 2 In some embodiments, the slide 3 comprises two housings 31 separated by a longitudinal vertical surface. The two housings 31 are detachably connected.

[0054] The rotational connection between the first shaft 4a and the slide 3, the rotational connection between the second shaft 51 and the slide 3, and the arrangement of the transmission pair 52 between the first shaft 4a and the second shaft 51 are all relatively convenient.

[0055] Please refer to Figure 3 and Figure 5 The third shaft 53 is telescopic up and down in the second shaft 51, that is, the second shaft 51 is hollow for the third shaft 53 to pass through. The third shaft 53 rotates together with the second shaft 51, and more specifically, the inner wall of the second shaft 51 has a limiting protrusion, and the outer wall of the third shaft 53 has a matching limiting groove 53a.

[0056] The bottom end of the third shaft 53 passes through the strip-shaped through slot 2a. The limiting block 54 is connected to the third shaft 53 above the support surface. The second gear 55 has the same number of teeth and module as the first gear 4 and is fixedly connected to the third shaft 53 below the support surface.

[0057] The spring 56 acts on the third shaft 53, and more specifically, the spring 56 is a compression spring 56 sleeved on the third shaft 53; the upper end of the spring 56 abuts against the bottom surface of the second shaft 51, and the lower end abuts against the limiting block 54. Through the action of the spring 56:

[0058] The limiting block 54 is kept in the state of supporting the slide 3 against the support surface, that is, for the connection of the limiting block 54 and the third shaft 53, the limiting block 54 is limited to move up and down relative to the third shaft 53.

[0059] It also keeps the second gear 55 in the state of engaging with the second rack 2b to limit the movement of the slide 3, that is, if the second shaft 51 and the first gear 4 rotate in opposite directions, the first rack 1a is on the first side of the first gear 4, and the second rack 2b is also on the first side of the second gear 55, if the second shaft 51 and the first gear 4 rotate in the same direction, the first rack 1a is on the first side of the first gear 4, and the second rack 2b is on the second side of the second gear 55.

[0060] In summary, the two sets of gear and rack interlock to limit the movement of the slide 3, so that the slide 3 is stably kept on the mounting strip 1 and the support strip 2. When the position of the slide 3 needs to be adjusted, the third shaft 53 is manually operated to overcome the effect of the spring 56 on the third shaft 53, so that the third shaft 53 moves upward, and correspondingly, the limiting block 54 leaves the support surface, and the second gear 55 disengages from the second rack 2b. The interlocking of the two sets of gear and rack is released, so that the slide 3 can be moved. During the movement, the first gear 4 rotates and drives the second gear 55 to rotate through the transmission pair 52. Therefore, after the slide 3 is moved to the corresponding position, the third shaft 53 is released, the second gear 55 can be engaged with the second rack 2b again, the two sets of gear and rack interlock again to limit the movement of the slide 3.

[0061] Please refer to Figure 3 and Figure 5 In some embodiments, the limiting block 54 and the third shaft 53 are fixedly connected, and more specifically, they can be integrated. The bottom end of the third shaft 53 is the position for manually operating the third shaft 53, and more specifically, the bottom surface of the support strip 2 also has a strip-shaped through slot 2a for the third shaft 53 to pass through.

[0062] Please refer to Figure 4 and Figure 6 In some embodiments, the limiting block 54 and the third shaft 53 are rotatably connected, and more specifically, the third shaft 53 has a thread, and the limiting block 54 is sleeved with a stepped nut 54a which is threadedly connected to the thread. Correspondingly, the lower end of the spring 56 can also abut against the nut 54a. The limiting block 54 is the position for manually operating the third shaft 53.
