DETAILED DESCRIPTION

[0032] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 11 , the present invention provides a technical solution:

[0034] Embodiment 1, an auxiliary pleating mechanism for sewing curtain pleats, comprises: curtain fabric 1.

[0035] Specifically, a sliding vertical plate 2 is provided on the side of the curtain fabric 1, and the curtain fabric 1 itself is kept in horizontal transportation. The sliding vertical plate 2 can limit the position of the curtain fabric 1 on the side to prevent the curtain fabric 1 from shifting in its width direction during transportation. A stop roller 28 is rotatably installed on the front of the sliding vertical plate 2, and the stop roller 28 is located on the upper side of the curtain fabric 1. The stop roller 28 is set to block the upper side of the curtain fabric 1, such as Figure 2As shown, when the device pleats the curtain fabric 1, the middle part of the curtain fabric 1 is pulled upward, and at this time, the blocking roller 28 will block the curtain fabric 1 in the middle part of the curtain fabric 1, so that the curtain fabric 1 forms an "M"-shaped fold in the middle position. In addition, a pressing frame 3 is provided on both sides of the blocking roller 28, and the pressing frame 3 is slidably connected to the sliding vertical plate 2. The two pressing frames 3 can slide in the horizontal direction, and the sliding directions are opposite, so as to achieve mutual distance or approach. The two pressing frames 3 are symmetrically distributed, as shown in FIG. Figure 2 As shown, after an "M"-shaped fold is formed in the middle of the curtain fabric 1, the two pressing frames 3 move closer to each other and can squeeze and press the "M"-shaped fold from the middle. At this time, the multiple layers of curtain fabric 1 on the fold fit together, so that subsequent sewing work can be facilitated;

[0036] Secondly, a reversing roller 31 is rotatably installed at the lower end of the pressing frame 3. The reversing roller 31 is used to bend and change the direction of the curtain fabric 1, and the surface of the reversing roller 31 itself is a curved surface, which can prevent the curtain fabric 1 from having creases at this position. A linkage plate 32 is rotatably installed on the outer side of one end of the rotating shaft of the reversing roller 31. One end of each of the two linkage plates 32 is rotatably installed with a forming roller 33, and the two forming rollers 33 are relatively fixed by a connecting frame 34. The forming roller 33 is located on the lower side of the curtain fabric 1, and the forming roller 33 slides vertically between the reversing roller 31 and the stop roller 28. The setting of the forming roller 33 mainly slides upward and pushes the middle part of the curtain fabric 1 to deform upward, such as Fig.11 The figure shows the initial state of the curtain fabric 1. At this time, the curtain fabric 1 is transported normally. When it is necessary to pleat the specified position of the curtain fabric 1, the forming roller 33 is moved upward and the middle part of the curtain fabric 1 is pushed to deform upward. However, since the two forming rollers 33 are respectively located on both sides of the stop roller 28, and the height position of the stop roller 28 itself remains unchanged, the forming roller 33 and the stop roller 28 cooperate with each other during the upward movement of the forming roller 33 to form "M"-shaped folds on the curtain fabric 1. Since the forming roller 33 and the stop roller 28 can both rotate, the curtain fabric 1 can be transported and moved for a certain distance to adapt to the forming of the folds. In addition, the folds after forming are all arc-shaped at the bending parts and will not be affected by In order to avoid creases caused by pressure, thereby avoiding affecting the aesthetics, a sewing mechanism and a shuttle mechanism are respectively installed in the middle of the two pressing frames 3. The sewing mechanism and the shuttle mechanism are structures known in the prior art, and are mainly used to sew the wrinkles of the fabric. Their role in this device is mainly to sew and fix the "M"-shaped wrinkles. In addition, after the wrinkles are sewn, the sliding vertical plate 2 of the device slides in the direction away from the curtain fabric 1, and the blocking roller 28, the forming roller 33 and the pressing frame 3 can be removed from the curtain fabric 1, so that the curtain fabric 1 together with the "M"-shaped wrinkles can be transported and moved, and then the sliding vertical plate 2 is reset, and pleating can continue at other positions on the curtain fabric 1.

[0037] In order to guide and limit the sliding of the sliding vertical plate 2, the present application also has a base 6 arranged below the sliding vertical plate 2, the base 6 itself is installed on a workbench or an external mounting frame to ensure that its position is fixed, side baffles 61 are fixed above both sides of the base 6, and the sliding vertical plate 2 is located between the two side baffles 61, and two guide shafts 63 are movably penetrated at both ends of the sliding vertical plate 2, and the two ends of the guide shaft 63 are respectively fixedly connected to the two side baffles 61, such as Fig.10 As shown, the guide shaft 63 can be used to guide and limit the movement of the sliding vertical plate 2, ensuring that the sliding vertical plate 2 can only approach or move away from the curtain fabric 1. In addition, the four guide shafts 63 cooperate with each other to limit the installation direction of the sliding vertical plate 2, ensuring that the sliding vertical plate 2 itself always remains vertically placed and does not tilt or fall. The two side baffles 61 can respectively limit the side edges of the curtain fabric 1 and the sliding of the sliding vertical plate 2, avoiding the curtain fabric 1 from deviating during transportation and movement, and preventing the sliding vertical plate 2 from detaching from the guide shaft 63.

[0038] In order to drive the sliding vertical plate 2 to slide, the present application also has a limit roller 64 rotatably sleeved on the outer side of one end of the guide shaft 63, and the four limit rollers 64 are respectively located on the upper and lower sides of both ends of the curtain fabric 1, such as Fig.10 As shown, the setting of the limiting roller 64 can, on the one hand, convey and limit the curtain fabric 1 to ensure that the curtain fabric 1 remains horizontal above the base 6, and on the other hand, limit the sliding of the sliding vertical plate 2 to prevent the sliding vertical plate 2 from sliding too far when it slides close to the curtain fabric 1 and squeezing the curtain fabric 1. Figure 2 As shown, the spacing between the limiting rollers 64 located on the upper and lower sides of the curtain fabric 1 is greater than the thickness of the curtain fabric 1 itself. After the "M"-shaped pleats are formed and sewing is completed, the curtain fabric 1 continues to be conveyed and moved to drive the pleats to pass through the gap between the upper and lower limiting rollers 64. A horizontal cylinder 62 is fixedly installed on the side of a side baffle plate 61. The movable end of the horizontal cylinder 62 movably penetrates a side baffle plate 61 and is fixedly connected to the back of the sliding vertical plate 2. The setting of the horizontal cylinder 62 is mainly used to drive the sliding vertical plate 2 to slide. In order to ensure the sliding stability of the sliding vertical plate 2, the horizontal cylinder 62 is set in groups of two and is symmetrically distributed at both ends of the sliding vertical plate 2 in the horizontal direction.

[0039] In order to guide the sliding of the reversing roller 31 and the forming roller 33, the present application also has a guide groove 24 and a vertical groove 25 formed on the surface of the sliding vertical plate 2, and a guide slider 311 is fixedly provided at one end of the rotating shaft of the reversing roller 31. Figure 3 As shown, the guide slider 311 itself is fixedly connected to the surface of the pressing frame 3, and the guide slider 311 is located in the inner cavity of the guide slot 24 and is slidably connected thereto, as shown in FIG. Figure 5The cam 33 is provided with two connecting rods 34 and 35, and the connecting rod 34 is provided with two connecting rods 34. The ...

[0040] In order to further prevent the clamping frame 3 from rotating, the present application also has an anti-deflection slide groove 26 and an avoidance groove 27 that penetrate through the surface of the sliding vertical plate 2, an anti-deflection protrusion 35 is fixedly installed on the upper side of one end surface of the clamping frame 3, and the anti-deflection protrusion 35 is slidably installed in the inner cavity of the anti-deflection slide groove 26, the anti-deflection slide groove 26 is used to limit and guide the sliding of the anti-deflection protrusion 35, and at the same time, the anti-deflection protrusion 35 and the guide slider 311 cooperate with each other to further prevent the clamping frame 3 from rotating and tilting. In addition, a driving screw 38 is rotatably installed in the middle part of the clamping frame 3, one end of the driving screw 38 extends to the outside of the clamping frame 3 and is movably connected with the avoidance groove 27, a linkage gear 381 is fixedly arranged on the outside of one end of the driving screw 38, and the linkage gear 381 is located on the back of the sliding vertical plate 2, and the avoidance groove 27 is mainly used to prevent the movement of the driving screw 38 from being hindered.

[0041] In order to avoid collision and interference between the linkage gear 381 and the linkage plate 32, the present application also has a backing plate 312 fixedly arranged on the outer side of the guide slider 311, and a gap is left between the linkage plate 32 and the back side of the sliding vertical plate 2 for the linkage gear 381 to move. Figure 3 and Figure 5 It can be seen that the pad 312 is placed on the inner side of the linkage plate 32. On the one hand, it is used to prevent the guide slider 311 from escaping from the inner cavity of the guide slot 24. On the other hand, it can form a gap between the linkage plate 32 and the back of the sliding vertical plate 2 for the linkage gear 381 to be installed, ensuring that the linkage gear 381 and the linkage plate 32 are respectively located in two vertical planes to avoid collision and interference with each other. The two linkage gears 381 are close to each other and mesh with each other. The other end of the drive screw 38 is installed with a drive motor 382 that drives the drive screw 38 to rotate. Figure 5 and Fig. 9It can be seen that when the two clamping frames 3 approach each other to the closest position, the two interlocking gears 381 can mesh with each other for transmission, and the driving screws 38 in the two clamping frames 3 can maintain synchronous reverse rotation. Conversely, when the two clamping frames 3 move away from each other until the two interlocking gears 381 separate from each other, the two driving screws 38 cannot maintain synchronous rotation.

[0042] In order to achieve the sewing fixation of the pleats, the present application also has guide slide bars 37 fixedly connected to the pressing frame 3 on both the upper and lower sides of the driving screw 38, the sewing mechanism includes a sewing seat 4 and a sewing needle 41, the sewing seat 4 is provided with a sliding sleeve 44 and a threaded sleeve 45, and the sliding sleeve 44 and the threaded sleeve 45 are respectively sleeved on the outer side of a group of guide slide bars 37 and the driving screw 38, combined with Figure 3 , Figure 4 and Figure 7 As shown, the sewing seat 4 can be driven to slide in the inner cavity of a pressing frame 3 by a driving screw 38, and the setting of the guide slide bar 37 can be used to guide the sliding direction of the sewing seat 4 and prevent the sewing seat 4 from rotating. The shuttle mechanism includes a shuttle seat 5, and the shuttle seat 5 is provided with a second sliding sleeve 55 and a second threaded sleeve 56, and the second sliding sleeve 55 and the second threaded sleeve 56 are respectively sleeved on the outer side of another group of guide slide bars 37 and the driving screw 38, combined with Figure 3 and Figure 8 As shown, the shuttle seat 5 is driven to slide in the inner cavity of the other pressing frame 3 by the driving screw 38. Combined with the above, when the two pressing frames 3 approach each other until the two linkage gears 381 are meshed with each other, the pressing frames 3 press the "M"-shaped folds, and the two driving screws 38 rotate synchronously and drive the sewing mechanism and the shuttle mechanism to move synchronously in the same direction. Then the sewing mechanism and the shuttle mechanism cooperate with each other to sew and fix the "M"-shaped folds. In addition, after the two pressing frames 3 move away from each other, the relative positions of the sewing mechanism and the shuttle mechanism can be adjusted separately to ensure that the two always remain corresponding.

[0043] In order to sew the wrinkles, the present application also has a controller 42 and a wire-releasing box 43 fixedly installed on the sewing seat 4 to drive the sewing needle 41 to work. The controller 42 is used to control the reciprocating extension and contraction of the sewing needle 41, and the wire-releasing box 43 is used to release the needle thread on the sewing needle 41. A wire-releasing device 51 controlled by a wire-releasing motor 53 and a shuttle body 52 controlled by a shuttle motor 54 are rotatably installed in the inner cavity of the shuttle seat 5. The notch of the sewing needle 41 and the shuttle body 52 are directly opposite to each other. The shuttle body 52 swings and rotates, and the corner of its notch can hook the needle thread on the sewing needle 41, and the thread releaser 51 releases another needle thread to be entangled with the needle thread on the sewing needle 41 hooked by the shuttle body 52, thereby realizing the sewing of the folds on the curtain fabric 1. In addition, a sewing slot 36 for the sewing needle 41 to pass through is opened through the inner wall of the pressing frame 3, and the sewing slot 36 is in a horizontal long strip shape, so that the sewing needle 41 can sew the needle thread while moving.

[0044] In order to drive the forming roller 33 to move, the present application also has a cylinder seat 21 fixedly installed on the back of the sliding vertical plate 2, and the cylinder seat 21 is fixed with a vertical cylinder 22, and the movable end of the vertical cylinder 22 is fixedly connected with a connecting plate 23, and the two ends of the connecting plate 23 are respectively fixedly connected to one end of the rotating shaft of the two forming rollers 33. Figure 5 and Fig. 9 As shown, the vertical cylinder 22 mainly provides power for the movement of the forming roller 33. When working, it drives the connecting plate 23 to slide up and down in the vertical direction, thereby driving the two forming rollers 33 to move up and down synchronously.

[0045] In order to avoid creases on the surface of the curtain fabric 1, the two pressing frames 3 of the present application are parallel to each other on one side, and the corners of the pressing frames 3 are provided with rounded corners. The middle part of the curtain fabric 1 is in an "M" shape and is wound around the outer sides of the reversing roller 31, the forming roller 33 and the stop roller 28 in sequence. Fig.11 and Figure 2 It can be seen that the vertical surface of the pressing frame 3 is mainly used to press the folds horizontally, and the rounded corners are used to prevent scratches on the surface of the curtain fabric 1 and creases on the surface of the curtain fabric 1, thereby ensuring that the folds are in a stable position during the sewing process, and no creases will be generated on the surface of the curtain fabric 1 after sewing, which is more beautiful.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
