[0001] The invention relates to the technical field of curtain fabric processing equipment, and in particular to a curtain fabric folding wheel. Background Art

[0002] The curtain fabric folding wheel is used to press the curtains during the production process and assist the presser foot in feeding the cloth (hereinafter referred to as the mopping wheel) to prevent the curtain fabric from slipping and deflecting. The common cloth feeding method is to feed the cloth by cooperating with the presser foot and the teeth below. This cloth feeding method usually causes slippage, which makes the sewn stitches inconsistent in size and affects the aesthetics. For some special fabrics, there is a problem of difficulty in feeding the cloth, and it may even fail to work normally. In order to solve the problem of smooth cloth feeding of the sewing machine, the prior art provides a variety of mopping devices for the sewing machine.

[0003] The mop wheels used in the prior art mop devices can only drag a single type of curtain fabrics. Different curtain fabrics require different mop wheels, and the mop wheels need to be disassembled and replaced when different curtain fabrics need to be mopped. This is troublesome to operate and will affect the work efficiency of curtain production. Summary of the invention

[0009] Furthermore, it also includes a first rotating frame, which is rotatably connected to a side of the driving wheel away from the reduction motor, and a second rotating frame is rotatably connected to the first rotating frame. The outer side of the first rotating frame is fixedly connected to uniformly arranged closing plates, and the outer side of the second rotating frame is fixedly connected to uniformly arranged closing frames. The closing plates are located inside the closing frames, and both the closing plates and the closing frames can move inside the driving wheel. A driving component for driving the closing plates and the closing frames to move is provided inside the driving wheel.

[0010] Furthermore, the driving assembly includes a plurality of limit rods, and the plurality of limit rods are fixedly connected to the side wall of the guide plate. A first bevel gear is connected to the side of the first rotating frame close to the guide plate and the second rotating frame. A second bevel gear is rotatably connected to the inner wall of the driving wheel. The first bevel gear is meshed with the second bevel gear. An annular groove is formed in the first bevel gear close to the guide plate. The plurality of limit rods are located in the annular groove. A plurality of groups of limit blocks are slidably connected in the annular groove. A first spring is connected between each group of limit blocks and the first bevel gear.

[0011] Furthermore, the guide plate drives the limiting rod to rotate and contact the limiting block, and the limiting block drives the first bevel gear to rotate to drive the closing plate and the closing frame to rotate and close the driving wheel.

[0012] Furthermore, the sides of each of the limit blocks facing each other are arc-shaped.

[0013] Furthermore, it also includes symmetrically arranged sliders, which are slidably connected to the mounting frame, one of the rotating shafts passes through the sliders, and the tops of the sliders are rotatably connected to threaded rods, which pass through the mounting frame, and the tops of the mounting frame are rotatably connected to symmetrically arranged nuts, which pass through and engage with the nuts, and a flat belt is wound around the symmetrically arranged nuts via a pulley, and a plurality of prisms are fixed to the top of one of the nuts, and handles are placed between the plurality of prisms.

There is no need to disassemble and replace the entire driving wheel, and the operation is convenient, thereby ensuring the work efficiency of curtain production.

[0016] The guide plate is controlled to rotate by a reduction motor, so that the guide wheel drives the moving teeth to move, and then the driving wheel can be transformed between the gear shape and the cylinder. In this way, curtain fabrics of different materials can be further mopped, and the replacement flexibility is high, the operation is simple, and the applicability is strong.

[0017] The driving wheel can be transformed between a gear shape and a cylinder. During the transformation, the closing plate and the closing frame can be driven to rotate to open and close the driving wheel, so that the driving wheel can be transformed into a closed cylinder, thereby improving the flatness of the driving wheel after deformation, so that it can better adapt to the curtain fabric required for the mop.

[0018] By turning the handle, the nut is driven to rotate, and then the position of the threaded rod and the slider is adjusted, so that the slider drives the upper rotating shaft and the driving wheel to move up and down. In this way, fabrics of different thicknesses can be pressed and mopped, ensuring the mopping effect of the driving wheel and the driven wheel on the curtain fabric.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0036] Example 1: A curtain fabric folding wheel, see Figure 1-Figure 2 , including a mounting frame 1, on which two rotating shafts 11 are rotatably connected, a driven wheel 12 is connected to the left side of the rotating shaft 11 on the lower side, a detachable driving wheel 13 is installed on the left side of the rotating shaft 11 on the upper side, the driving wheel 13 is hollow inside, a rubber sleeve 14 is sleeved on the outer side of the driving wheel 13, the rubber sleeve 14 is toothed inside, and a transmission wheel 15 is fixedly connected to the right side of the rotating shaft 11 on the upper side.

[0037] When in use, the mounting frame 1 is fixed on the sewing machine, and then the belt is wound around the transmission wheel 15 and the power component of the sewing machine. Then, when the power component of the sewing machine rotates, the transmission wheel 15 and the upper rotating shaft 11 are driven to rotate, and the upper rotating shaft 11 drives the driving wheel 13 to rotate, and the driving wheel 13 then drives the driven wheel 12 to rotate through friction. The user places the curtain fabric between the driven wheel 12 and the driving wheel 13, so that the driving wheel 13 and the driven wheel 12 suppress the stitches of the curtain fabric, thereby keeping the stitches of the curtain fabric flat and free of wrinkles, and then the driving wheel 13 and the driven wheel 12 are used to rotate the curtain fabric. The wheel 12 is used to mop the curtain fabric. Different fabrics require the driving wheel 13 of different materials to prevent the fabric from slipping and deviating during the mopping process, which will affect the production effect of the curtain fabric. The user can select the material of the driving wheel 13 according to the material of the curtain fabric. When rubber material is required, the rubber sleeve 14 can be put on the driving wheel 13. When the rubber sleeve 14 is removed, the driving wheel 13 is in the shape of a gear and can mop the required curtain fabric. In this way, fabrics of different materials can be mopped without disassembling and replacing the entire driving wheel 13. The operation is convenient, thereby ensuring the work efficiency of curtain production.

[0038] Example 2: Based on Example 1, please refer to Figure 1-Figure 15 , also includes a fixed plate 2, the fixed plate 2 is fixedly connected to the inner wall of the driving wheel 13, the fixed plate 2 is provided with evenly arranged guide grooves on the right side, and the guide grooves of the fixed plate 2 are slidably connected with mobile teeth 21, the driving wheel 13 is rotatably connected with a guide plate 22 inside, the guide plate 22 is provided with evenly arranged oblique grooves, each of the right inner sides of the mobile teeth 21 is fixedly connected with a guide rod 23, each of the guide rods 23 is located in an adjacent oblique groove on the guide plate 22, the left side of the guide plate 22 is keyed to a ring gear 24, the left side of the driving wheel 13 is fixedly connected to a motor frame 25, a reduction motor 26 is installed on the top of the motor frame 25, a spur gear 27 is keyed to the output shaft of the reduction motor 26, and the spur gear 27 is meshed with the ring gear 24.

[0039] When it is necessary to replace the cylindrical driving wheel 13, the reduction motor 26 can be controlled to start by an external switch, and the output shaft of the reduction motor 26 drives the spur gear 27 to rotate, and then drives the ring gear 24 to rotate, and the ring gear 24 drives the guide plate 22 to rotate. When the guide plate 22 rotates, it drives the guide rod 23 to move inward through the inclined groove, and then pulls the moving tooth 21 to move inward and be collected into the driving wheel 13, so that the driving wheel 13 is deformed from a gear shape to a cylindrical shape. In this way, curtain fabrics of different materials can be further mopped, and the replacement flexibility is high, the operation is simple, and the applicability is strong. When the toothed driving wheel 13 is needed, the output shaft of the reduction motor 26 can be controlled to reverse.

[0040] The first rotating frame 3 is also included. The first rotating frame 3 is rotatably connected to the right side inside the driving wheel 13. The right side of the first rotating frame 3 is rotatably connected to the second rotating frame 31. The outer side of the first rotating frame 3 is fixedly connected with uniformly arranged closing plates 32. The outer side of the second rotating frame 31 is fixedly connected with uniformly arranged closing frames 33. The closing plates 32 are located inside the closing frames 33. Both the closing plates 32 and the closing frames 33 can move inside the driving wheel 13. A driving component for driving the closing plates 32 and the closing frames 33 to move is provided inside the driving wheel 13.

[0041] The driving assembly includes four limit rods 4, and the four limit rods 4 are fixedly connected to the right side of the guide plate 22. The left side of the first rotating frame 3 and the left side of the second rotating frame 31 are both keyed with a first bevel gear 41. The inner wall of the driving wheel 13 is rotatably connected with a second bevel gear 42. The two first bevel gears 41 are meshed with the second bevel gear 42. The first bevel gear 41 on the left side is provided with an annular groove 43. The four limit rods 4 are all located in the annular groove 43. Four groups of limit blocks 44 are slidably connected in the annular groove 43, and every two limit blocks 44 form a group. The outer side of each group of limit blocks 44 is connected to the first bevel gear 41 on the left side with a first spring 45, and the inner side of each limit block 44 is arc-shaped.

[0042] When the driving wheel 13 needs to change from a gear shape to a cylindrical shape, the guide plate 22 rotates clockwise, driving the limit rod 4 to rotate clockwise. When the moving tooth 21 is about to be retracted into the driving wheel 13, the limit rod 4 contacts the limit block 44, thereby driving the first bevel gear 41 and the second bevel gear 42 to rotate, so that the first rotating frame 3 and the second rotating frame 31 drive the closing plate 32 and the closing frame 33 to rotate in the opposite direction, thereby separating the closing plate 32 and the closing frame 33. When the moving tooth 21 is retracted into the driving wheel 13, the closing plate 32 and the closing frame 33 just close the driving wheel 13, so that the driving wheel 13 becomes a closed cylindrical shape. At this time, the guide plate 22 continues to drive the limit rod 4 to rotate over the limit block 44, and the first spring 45 performs adaptive deformation. When the driving wheel 13 needs to change from a cylindrical shape to a gear shape, the guide plate 22 rotates counterclockwise. The first spring 45 is adaptively deformed, and the guide plate 22 drives the moving tooth 21 to move out of the driving wheel 13, so that the driving wheel 13 can be deformed from the gear shape to the cylinder shape, and then the cylinder shape to the gear shape process, which is simple to operate, does not need to be disassembled and replaced, and has high working efficiency.

[0043] It also includes two sliders 5, which are slidably connected to the mounting frame 1, and the rotating shaft 11 on the upper side passes through the two sliders 5. The tops of the two sliders 5 are rotatably connected to threaded rods 51, and the two threaded rods 51 pass through the mounting frame 1. The top of the mounting frame 1 is rotatably connected to two nuts 52, and the two threaded rods 51 pass through the adjacent nuts 52 and mesh with the nuts 52. A flat belt 53 is wound around the two nuts 52 through a pulley, and four prisms 54 are fixedly connected to the top of the nut 52 on the right side, and a handle 55 is placed between the four prisms 54.

[0044] It also includes a moving block 6, which is slidably connected to the right front side of the mounting frame 1, a second spring 61 is connected between the top of the moving block 6 and the inside of the mounting frame 1, a short rod 62 is rotatably connected to the front side of the moving block 6, and a tensioning wheel 63 is fixedly connected to the right side of the short rod 62.

[0045] The user can adjust the distance between the driving wheel 13 and the driven wheel 12 according to the material and thickness of the curtain fabric, put the handle 55 on the prism 54, and then pass the belt wrapped around the driving wheel 15 and the power component of the sewing machine around the tensioning wheel 63, and then rotate the handle 55 forwards and backwards, and the handle 55 drives the nut 52 on the right side to rotate through the prism 54, and the nut 52 on the right side drives the nut 52 on the left side to rotate through the flat belt 53, so that the nut 52 drives the threaded rod 51 to move up and down, and the threaded rod 51 drives the slider 5 to move up and down to adjust. The slider 5 drives the rotating shaft 11 on the upper side to move up and down for adjustment, so that the distance between the driving wheel 13 and the driven wheel 12 can be adjusted, thereby ensuring the mopping effect of the driving wheel 13 and the driven wheel 12 on the curtain fabric, so as to avoid the inability to mop thinner or thicker curtain fabrics; as the transmission wheel 15 moves up and down for adjustment, under the action of the second spring 61 and the belt, the tensioning wheel 63, the short rod 62 and the moving block 6 move up and down, and the second spring 61 is adaptively deformed, so that it can be ensured that the driving wheel 13 can smoothly adjust its position.
