Technical Field

[0001] The present invention relates to the technical field of sewing machines, in particular to a sliding storage mechanism for a sewing machine. Background Art

[0002] Existing sewing machines sew large-format fabrics using an upper feed assembly with a roller presser foot and a lower feed assembly with a feed wheel. The roller presser foot and the feed wheel work together, sandwiching the fabric between them. The rotation of the roller presser foot and the feed wheel allows for feeding. In fabric sewing workshops, sewing machines are equipped with storage troughs for storing fabric to be sewn or finished fabric.

[0003] The existing sewing machine storage structure mainly adopts a sliding tray structure, which only has a simple item storage function. The fabric is piled up and entangled on the surface of the tray. Affected by the weight of the fabric, during the garment sewing process, the fabric needs to be transported slowly and evenly according to the sewing progress so that the fabric can move forward at a uniform speed along with the sewing progress. Since the sewing machine operating table is small, the fabric is generally dragged to the ground, and manual pushing of the fabric is required to avoid the problem of the fabric being stuck and stopped on the sewing machine surface due to the gravity of the fabric. The manual pushing method requires controlling the uniform speed of the fabric based on operating experience. The operation is cumbersome and requires high concentration. Long-term operation is prone to fatigue and has low production efficiency. In view of this, the existing problems are studied and improved, and a sliding storage mechanism for sewing machines is provided to solve the current problems. The purpose is to achieve the purpose of solving the problem and improving the practical value through this technology. Summary of the Invention

[0028] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0029] A sliding storage mechanism for a sewing machine provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] Combine Figure 1-6 As shown, the present invention provides a sliding storage mechanism for a sewing machine, comprising: a fixed base 100, an extension slide 200, and a driving rail 300. The driving rail 300 is provided in two groups and is symmetrically arranged on both sides of the extension slide 200. The driving rail 300 includes a lifting slide 310, a transverse slide 320, and a connecting sleeve 330 slidably sleeved on the surfaces of the lifting slide 310 and the transverse slide 320. The top surface of the lifting slide 310 is fixedly connected to the bottom surface of the fixed base 100. A connecting pin 340 is provided on one side of the transverse slide bar 320, which is fixedly connected to the side of the extension slide 200. The extension slide 200 includes a main storage tank 210, a fixed guide seat 230, and a plurality of slides 220. The slides 220 are slidably connected in sequence, with the main storage tank 210 slidably connected to the inner side of the main storage tank 210, and the fixed guide seat 230 slidably connected to the outer side of the slide 220. The ends of the main storage tank 210 and the slide 220 are fixedly connected to a linear actuator 240 for driving the sliding.

[0031] The lifting slide bar 310 and the transverse slide bar 320 have the same structure and are both provided with a fixed block 321, a first traction bar 322, and a second traction bar 323 inside. The first rotating pin 324 and the second rotating wheel 325 are rotatably installed at both ends of the lifting slide bar 310 and the transverse slide bar 320. The first traction bar 322 is fixed to the inner side of the lifting slide bar 310 and the transverse slide bar 320. The first traction bar 322 is wrapped around the surface of the second rotating wheel 325 at both ends and the end is fixedly connected to the two ends of the fixed block 321. The first rotating pin 324 is rotatably sleeved on the inner side of the second rotating wheel 325. The second traction bar 323 is wrapped around the surface of the first rotating pin 324 at both ends and the end is fixedly connected to the two ends of the connecting sleeve 330. The lifting slide bar 310 and the transverse slide bar 320 are respectively provided with a reduction motor 326 at both ends for driving the first rotating pin 324 and the second rotating wheel 325 to rotate.

[0032] In this embodiment, the lifting slide bar 310 and the transverse slide bar 320 are hollow metal tubular structures. Both ends of the lifting slide bar 310 and the transverse slide bar 320 are provided with blocking blocks, and the reduction motor 326 is fixed to the surface of the blocking blocks.

[0033] Furthermore, the reduction motor 326 at one end of the lifting slide bar 310 and the transverse slide bar 320 is used to drive the first rotating pin 324 to rotate, and the reduction motor 326 at the other end is used to drive the second rotating wheel 325 to rotate.

[0034] Specifically, two reduction motors 326 are used to control the movement of the fixed block 321 and the first traction bar 322 respectively, so as to realize dual-motor drive control of the movement of the lifting slide 310 and the transverse slide 320 relative to the connecting sleeve 330, thereby better controlling the reciprocating motion of the lifting slide 310 and the transverse slide 320 and improving the output torque.

[0035] In this embodiment, the reduction motor 326 is a harmonic reduction motor structure, and the input ends of the reduction motor 326 and the linear actuator 240 are electrically connected to a servo controller, and the input end of the servo controller is electrically connected to the main control end of the sewing machine.

[0036] Specifically, the sewing machine's electronic control terminal adaptively adjusts the working speed of the reduction motor 326 and the linear actuator 240 according to the rotation speed of the feed wheel.

[0037] In this embodiment, the connecting sleeve 330 is slidably sleeved on the outer sides of the lifting slide 310 and the transverse slide 320. The lifting slide 310 and the transverse slide 320 are arranged perpendicular to each other. The lifting slide 310 is vertically connected to the bottom surface of the sewing machine table through the fixed base 100.

[0038] In this embodiment, both sides of the fixed guide seat 230 are fixedly connected to the inner connecting pins 340 of the transverse sliding rod 320 , and the fixed guide seat 230 and the transverse sliding rod 320 are arranged in parallel.

[0039] Furthermore, several slide drawers 220 have the same structure and their volumes increase successively. The linear actuator 240 at the end of the upper slide drawer 220 is fixedly connected to the inner side of the lower slide drawer 220. The slide drawer 220 at the end of the main storage tank 210 is fixedly connected to the inner side of the smallest slide drawer 220, and the main storage tank 210 is slidably sleeved on the inner side of the smallest slide drawer 220.

[0040] Specifically, the multi-stage slide 220 performs an extension movement of the main storage tank 210 to achieve the traction and extension of the fabric, and after contraction, it realizes the storage function together with the fixed guide seat 230.

[0041] In this embodiment, a spring clip for fixing one end of the fabric is fixedly installed on the inner side of the main storage slot 210. The main storage slot 210, the slide drawer 220 and the fixed guide seat 230 are aluminum alloy components.

[0042] The working principle and use process of the present invention:

[0043] When using the sliding storage mechanism of the sewing machine, the fixed base 100 is fixed under the sewing machine table, and the extended slide drawer 200 and the transverse sliding rod 320 are completely stored and hidden under the sewing table for storage. Before starting work, one end of the fabric is fixed to the inside of the main storage groove 210, and all the fabrics are placed in the extended slide drawer 200 for storage. During sewing work, one end of the fabric is introduced into the roller presser foot and the feed wheel for clamping and clamping during sewing. The extended slide drawer 200 can be located at the lowest position by sliding the transverse slide rod 320 and the connecting sleeve 330 downward, so that the traction fabric is arranged in a vertical line, and the main storage groove 210 and the multiple slide drawers 220 are extended under the extension of the multiple linear actuators 240, so that one end of the traction fabric is extended as much as possible and laid flat in a straight line;

[0044] During sewing, the internal reduction motor 326 of the lifting slide 310 controls the connecting sleeve 330 to slide along the surface of the lifting slide 310, driving the transverse slide 320 and the extension slide 200 to move upward at a uniform speed as a whole to feed the material. When the extension slide 200 reaches the top, the linear actuator 240 controls the main storage tank 210 and the slide 220 to retract at a uniform speed, and feeds the material at a uniform speed following the sewing movement, thereby reducing the influence of gravity and friction during the movement of the fabric and improving the sewing effect.

[0045] Although the 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 invention, and that the scope of the invention is defined by the claims and their equivalents.
