Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a quick disassembly and installation device for the inner frame of an embroidery machine frame and an embroidery machine. Background Technique

[0002] There are various types and specifications of embroidery machines. At present, there is no unified classification method. Generally speaking, the following classification methods are commonly used: classified by the number of machine heads, it can be divided into single-head and multi-head machines; classified by the number of machine needles contained in each head, it can be divided into single-needle and multi-needle; classified by the form of the feeding tensioning frame, it can be divided into plate type and simple type; classified by the stitch form used in embroidery, it can be divided into lock stitch and chain stitch. Since each machine type has problems such as the number of machine heads, the number of machine needles, the form of the tensioning frame, and the stitch form, by combining and arranging these and refining the classification, the number of embroidery machine types will be a very large number. Therefore, it can meet the needs of customers at different levels, scales, and requirements. At present, most embroidery machines use an embroidery frame to clamp the fabric to assist in completing the embroidery work on the fabric. At present, most of the embroidery frames use a method of pressing and combining multiple pressing plates to fix the fabric. However, this clamping method is complicated to operate and the clamping effect is not obvious, resulting in the movement of the fabric during embroidery and affecting the embroidery effect.

[0003] To solve the above technical problems, a Chinese patent with the publication number of CN220812904U in the prior art discloses an embroidery machine frame, including a fixed frame of the embroidery machine. Sliding grooves are opened on both sides of the fixed frame of the embroidery machine. A connecting strip is slidably connected in the sliding grooves. A lower clamping plate is connected to the connecting strip. Connecting plates are connected to the front and rear of the lower clamping plate. A first frame plate is connected to the connecting plate located in front of the lower clamping plate. A connecting rod penetrates through the connecting plate. A plurality of rod sleeves are rotatably connected to the connecting rod. An upper clamping plate is connected to the rod sleeves. A fixed toothed plate is connected to the lower part of the upper clamping plate. A telescopic rod is connected in the groove. A sliding toothed plate is connected to the lower part of the telescopic rod.

[0004] Although the above prior art solution enhances the fixing effect of the fabric and avoids the movement of the fabric during embroidery, after the upper clamping plate and the lower clamping plate are fitted together, the locking and unlocking between the two both require the staff to rotate each group of bolts one by one, increasing the labor intensity of the staff and the downtime during the feeding of the embroidery machine, thereby affecting the work efficiency.
