Technical Field

[0001] The utility model relates to the technical field of automatic lock-sewing machines, in particular to an automatic lock-sewing machine for curtain production and processing. Background Art

[0002] Curtains are made of cloth, linen, yarn, aluminum sheets, wood chips, metal materials, etc. They have the functions of sunshade, heat insulation and regulating indoor light. Curtains are divided into cotton gauze, polyester cloth, polyester-cotton blended, cotton-linen blended, non-woven fabrics, etc. Different materials, textures, colors, patterns, etc. are combined to form curtains of different styles, which are matched with interior design curtains of different styles. The fabric patchwork or lock cloth heads are processed by automatic lockstitching machines. Lockstitching usually has two meanings: one refers to wrapping the raw edges or seams of fabrics or clothing pieces with sewing thread to lock them to prevent them from falling off and spreading; the other refers to tying a knot, which is also to reinforce the stitches, and repeatedly zigzag lockstitching back and forth to reinforce the stress points.

[0003] For example, a Chinese patent (publication number: CN211112565U) discloses an automatic lock-sewing machine for curtain production and processing, including a base, two side panels are fixedly installed on the top of the base, the same control seat is fixedly installed on the top of the two side panels, one side of the two side panels is provided with a fixing hole, a movable seat is slidably installed in the two fixing holes, the bottom of the two movable seats is provided with a mounting groove, the two mounting grooves are slidably installed with a mounting seat, and the bottom of the two mounting seats is fixedly installed with a clamping plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 In this embodiment, an automatic lock-stitching machine for curtain production and processing includes a workbench 1, four bases are fixed to the lower surface of the workbench 1, a lock-stitching machine body 4 is fixed to the right side of the upper surface of the workbench 1, a protective plate 3 is fixed to the left side of the workbench 1, and a limiting mechanism 2 is provided on the workbench 1 and the protective plate 3.

[0022] See also Figure 1-3In order to facilitate the device to be applicable to more sizes of curtains to be locked, the limiting mechanism 2 in this embodiment includes an adjusting component arranged on the workbench 1 and the protective plate 3, a first connecting plate 207 arranged on the adjusting component, a threaded rod 208 fixed to the top of the first connecting plate 207, a second connecting plate 213 fixed to the right side of the upper surface of the workbench 1, and a limiting component arranged on the second connecting plate 213 and the first connecting plate 207.

[0023] Among them, the adjustment component includes an adjustment motor 203 fixed to the left side of the protective plate 3, two driving rods 201 rotatably connected between the left and right sides of the inner wall of the workbench 1, an adjustment slider 202 threadedly connected to the outer surface of the driving rod 201, a first transmission wheel 204 fixed to the outer surface of the front driving rod 201, a second transmission wheel 205 fixed to the outer surface of the back driving rod 201, and a conveyor belt 206 transmission-connected between the second transmission wheel 205 and the first transmission wheel 204, so as to drive the driving rod 201 to rotate, thereby providing a power source for the stable movement of the conveyor belt 206, and adjusting the distance between the first connecting plate 207 and the second connecting plate 213, so as to facilitate the subsequent locking of the lock-seam curtains.

[0024] At the same time, the limiting component includes a connecting through hole 214 opened on the upper surface of the first connecting plate 207 and the second connecting plate 213, a threaded rod 208 slidably connected to the inner wall of the connecting through hole 214, a fixing plate 209 fixed to the bottom of the threaded rod 208, an adjusting nut 211 threadedly connected to the outer surface of the threaded rod 208, a spring 212 sleeved on the outer surface of the threaded rod 208, and a rotating shaft 210 rotatably connected between the left and right sides of the inner wall of the fixing plate 209. The cross-sections of the protective plate 3 and the rotating shaft 210 are both U-shaped, which is convenient for limiting the position of curtains of different sizes to be locked, so that curtains of different sizes to be locked can always remain flat and will not deviate during the subsequent locking steps.

[0025] In addition, a movable hole is provided on the upper surface of the workbench 1, and the first connecting plate 207 is slidably connected to the movable hole. The lower surface of the conveyor belt 206 slides in contact with the inner bottom wall of the workbench 1, so that the conveyor belt 206 moves more stably, and the movement of the first connecting plate 207 is more stable, which can drive the rotating shaft 210 to move stably, so as to facilitate the directional limitation of curtains of different widths to be locked.

[0026] In addition, the output shaft of the adjusting motor 203 is fixed to the left end of the front driving rod 201, and the left end of the back driving rod 201 is rotatably connected to the inner right side wall of the protective plate 3, providing more support for the stable rotation of the driving rod 201 itself, so that the driving rod 201 can more stably drive the conveyor belt 206 located on the outer surface of the driving rod 201 to move, and the spring 212 is located between the first connecting plate 207 and the fixed plate 209. The cross-sections of the first connecting plate 207 and the second connecting plate 213 are both L-shaped, so that the rotating shaft 210 will not be over-extruded when restricting the curtains to be locked, which is convenient for subsequent steps.

[0027] The working principle of the above embodiment is:

[0028] According to actual needs, the operator can start the adjustment motor 203 to drive the front driving rod 201 and the first transmission wheel 204 on the front driving rod 201 to rotate, so that the first transmission wheel 204 drives the second transmission wheel 205 to rotate through the conveyor belt 206, and then the back driving rod 201 will also rotate. Since the left end of the back driving rod 201 is rotatably connected to the right inner wall of the protective plate 3, more support force can be provided for the rotation of the driving rod 201, so that the two driving rods 201 can rotate more stably, and then the conveyor belt 206 located on the outer surface of the driving rod 201 can be driven to move more stably, so that the first connecting plate 207 can move more smoothly along the moving hole. At the same time, since the lower surface of the conveyor belt 206 fits and slides with the inner bottom wall of the workbench 1, it also further promotes the more stable movement of the conveyor belt 206. According to actual conditions, the relative distance between the first connecting plate 207 and the second connecting plate 213 can be adjusted to allow different widths of windows to be locked. The curtain is subsequently fixed so that curtains of more sizes can be used in the equipment. The position of the adjusting nut 211 on the outer surface of the threaded rod 208 can also be adjusted according to the thickness of the curtain to be locked, and then the relative distance between the rotating shaft 210 and the curtain to be locked located on the upper surface of the workbench 1 can be adjusted, so that the curtains of different thicknesses and widths that need to be locked can be positioned and flattened, so that the curtains of different sizes to be locked can always move in a relatively stable direction when being locked through the lock-sewing machine body 4, and will not deviate while being kept flat, thereby ensuring the accuracy of the lock-sewing. At the same time, when the curtain is long, there is no need to manually fix the curtain again, and the unlocked part can be smoothly and stably transferred to the bottom of the lock-sewing machine body 4 for locking, which saves time and effort. Due to the elastic force of the spring 212 between the fixing plate 209 and the first connecting plate 207 or the second connecting plate 213, the rotating shaft 210 will not be excessively squeezed when restricting the curtain to be locked, which is more conducive to the processing of subsequent steps.
