Description

Technical Field

[0001] This utility model relates to the field of material feeding structures, specifically a material feeding structure for an automatic sewing machine. Background Technology

[0002] As an important textile machine, the sewing machine has undergone a long technological evolution. Early manual sewing was inefficient and labor-intensive. With the rise of the Industrial Revolution, the demand for mechanized sewing became urgent. At the end of the 18th century, the Englishman Thomas Sander invented the world's first practical sewing machine, laying the foundation for the modern sewing machine. Subsequently, many inventors continuously improved the sewing machine, gradually perfecting its structure and function. For example, the emergence of lockstitch technology improved sewing quality, and foot-operated drive replaced manual operation, greatly improving work efficiency. In the 20th century, the application of electric motors enabled the sewing machine to be automated, and the integration of electronic technology further promoted its intelligent development, enabling functions such as automatic thread breakage detection and multiple stitch selection.

[0003] An existing automatic sewing machine's feeding structure typically includes a set of mounting platforms with through slots. When materials accumulate on the mounting platforms, they are manually pushed into the through slots to complete the feeding process.

[0004] However, for the existing automatic sewing machine's feeding structure, manually pushing the material into the slot to complete the feeding process is cumbersome and wastes manpower. At the same time, the material passing through the rotating plate will accumulate together. After working for a long time, the accumulated material will come into contact with the rotating plate, making the rotating plate unusable and affecting the normal feeding of the device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a feeding structure for an automatic sewing machine to solve the technical problem mentioned in the background art that the feeding structure of the existing automatic sewing machine has poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding structure for an automatic sewing machine, comprising an installation platform, a support plate fixedly installed on the top of the installation platform, a hinge fixedly installed on one side of the support plate, a slide plate fixedly installed on one side of the hinge, a sliding base fixedly installed on the bottom of the slide plate, a vertical rod fixedly installed on the bottom of the slide plate, a sleeve rod fixedly installed at one end of the vertical rod, a vertical plate fixedly installed on the bottom of the installation platform, a hydraulic rod movably installed inside the vertical plate, a limiting plate fixedly installed on the bottom of the installation platform, a side groove opened in the limiting plate, a sliding rod sleeved in the side groove, a locking block provided at the bottom of the sliding rod, a crossbar fixedly installed between the locking blocks, a limiting rod fixedly installed at the bottom of the sliding rod, and a rotating plate movably installed between the limiting rods.

[0007] By adopting the above technical solution, the problem of poor material feeding structure in existing automatic sewing machines mentioned in the background art is solved. By setting up a sliding plate, when material accumulates on the sliding plate, the retracting hydraulic rod can drive the sliding plate to rotate to one side. The hydraulic rod is movably installed inside the vertical plate, which is fixedly installed at the bottom of the mounting platform. One end of the hydraulic rod is sleeved in the sliding base on one side of the sliding plate, so that the material accumulated on the top of the sliding plate can fall into the receiving box in the mounting platform, avoiding material accumulation and affecting the normal use of the device. At the same time, raising the hydraulic rod to drive the sliding plate to rotate improves the material feeding effect and enhances the practicality of the device.

[0011] Preferably, a receiving box is installed inside the installation platform to prevent materials from falling into the platform and requiring manual collection. The limiting rod and the rotating plate are fitted inside the receiving box so that the rotating plate can push the materials that are piled up too high, so that the materials can be dispersed in the receiving box and prevent the materials from piling up too high, which would affect the normal use of the device.

[0012] The present invention is further configured such that a side groove is provided on one side of the receiving box, and the cross-sectional area of ​​the side groove is larger than the cross-sectional area of ​​the rotating plate.

[0013] Preferably, a side groove is provided on one side of the receiving box, and the cross-sectional area of ​​the side groove is larger than that of the rotating plate. This allows the receiving box to be smoothly removed from the installation platform after collection, avoiding collisions between the receiving box and the limiting rod and the rotating plate, which would affect the normal use of the device.

[0014] The present invention is further configured such that a mounting plate is provided on one side of the limiting plate, and the limiting plate is fixedly installed on the bottom of the mounting platform by the mounting plate.

[0015] Preferably, by providing an installation plate on one side of the limiting plate, the limiting plate is fixedly installed at the bottom of the installation platform, thereby achieving the effect of fixed installation.

[0016] The present invention is further configured such that the thickness of the slide bar is the same as the thickness of the side groove, and the inside of the side groove is smoothly arranged.

[0017] Preferably, by setting the thickness of the slide rod to be the same as the thickness of the side groove, the slide rod can be stably installed in the side groove. The inside of the side groove is smoothly arranged to reduce the friction generated when the slide rod slides in the side groove, thereby improving the practicality of the device.

[0018] The present invention is further configured such that a through groove is provided inside the sleeve rod, and the diameter of the through groove is the same as the diameter of the crossbar.

[0019] Preferably, a through groove is provided inside the sleeve rod, the diameter of which is the same as the diameter of the crossbar, so that the slide can push the slide rod through the vertical rod.

[0020] The present invention is further configured such that a cavity is formed inside the tray, and the cross-sectional area of ​​the slide plate is the same as the cross-sectional area of ​​the cavity.

[0021] Preferably, by creating a cavity inside the pallet, the cross-sectional area of ​​the slide plate is the same as that of the cavity, allowing materials to accumulate on the slide plate, thereby completing the unloading process.

[0022] The present invention is further configured such that the surface of the slide plate is smooth, and the diameter of the sleeve is larger than the diameter of the vertical rod.

[0023] Preferably, by making the surface of the slide plate smooth, the material can be smoothly fed through the slide plate, avoiding excessive friction between the material and the slide plate, which would affect the normal sliding of the material. The diameter of the sleeve rod is larger than the diameter of the vertical rod, so that the sleeve rod can achieve the desired effect.

[0024] The present invention is further configured such that the length of the sleeve rod is the same as the length of the crossbar, and the surface of the crossbar is smooth.

[0025] Preferably, by making the length of the sleeve rod the same as the length of the crossbar, the sleeve rod can be stably installed between the locking blocks, and the surface of the crossbar is smoothly set to reduce the friction between the sleeve rod and the crossbar, thereby improving the practicality of the device.
