[0002] Embroidery is a traditional handicraft that mainly uses needle and thread to embroider certain patterns and colors on fabric to create decorative patterns or designs. In the traditional embroidery process, the base fabric serves as the basis for embroidery, and its role is to support and carry the exquisite patterns. Depending on the design and end use, it is sometimes necessary to cut and trim the base fabric.

[0003] According to the Chinese patent publication number: CN219906380U, a base fabric trimming device for embroidery craft includes a bracket, a winding roller is rotatably connected to the inside of the bracket, a screw rod is rotatably connected to the inside of the bracket, a limit rod is fixed inside the bracket, a rotating shaft is rotatably connected to the inside of the bracket, a connecting ring is slidably connected to the outer surface of the limit rod, a clamping assembly is constructed at the top and bottom of the connecting ring, a distance adjustment assembly is constructed at the outer surface of the screw rod, a driving motor is installed on one side of the bracket, the output end of the driving motor is fixedly connected to the winding roller, a trimming knife is arranged on the outer surface of the rotating shaft, a driven wheel is fixed to one end of the rotating shaft, a driving wheel is fixed to one end of the winding roller, and the driving wheel is connected to the driven wheel by a belt.

[0004] In the above scheme, the sliding block drives the connecting ring to move, and then drives the connecting bearing to move, thereby driving the trimming knife to move, and then drives the wedge block of the trimming knife to slide in the wedge groove. However, in actual embroidery technology, most of the stretched cloth is elliptical or circular, so the above scheme can only perform linear base cloth trimming, which makes the application range of the base cloth trimming device not high. Utility Model Content

[0005] The utility model aims to provide a base fabric trimming device for embroidery craft, so as to solve the problem that only straight line base fabric trimming can be performed, so that the base fabric trimming device has a limited application range.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a base fabric trimming device for embroidery craft, including a protective cover, a positioning hole is opened on the top surface of the protective cover, a driving motor is detachably fixed on the top surface of the positioning hole, an axis locking mechanism is fixed on the output end of the driving motor, a cloth cutting saw blade is detachably fixed to the output end of the driving motor through the axis locking mechanism, a front protective cover is arranged on the front side of the protective cover, a guide opening is opened on the front side of the front protective cover, and the guide opening is a V-shaped structure.

[0007] Preferably, a fixing block is fixed to the rear side of the protective cover, a handle is fixed to the rear side of the fixing block, and the front side of the protective cover is rotatably connected to two side protective covers via hinges.

[0008] Preferably, a plurality of limit pins are fixed to the rear side of the front shield, a plurality of limit slots are provided on the front side of the shield, and the limit pins are plugged into the limit slots.

[0009] Preferably, barb blocks are fixed to the sides of the two side protective covers that are close to each other, and barb bayonet sockets are respectively provided on the left and right sides of the front protective cover, and the barb blocks are snap-connected with the barb bayonet sockets.

[0010] Preferably, the front side and the rear side of the fixing block and the front side and the rear side of the handle are penetrated with wire harness reserved holes, and the outer wall of the handle is fixed with a non-slip rubber sleeve.

[0011] Preferably, a fixing ring is fixed to the outer wall of the driving motor, a plurality of thread grooves are provided on the top surface of the protective cover, a through hole for sleeve bolts is provided on the fixing ring, and the threaded end of the bolt is threadedly connected to the thread groove.

[0012] Compared with the prior art, the embroidery base fabric trimming device using the above technical solution has the following beneficial effects:

[0013] 1. During use, the staff starts the drive motor, and the output end of the drive motor will drive the cloth cutting saw blade to rotate. The staff manually picks up the entire device and pulls the base fabric that needs to be trimmed upwards, so that the base fabric that needs to be trimmed is in a stretched state. At this time, the entire device is pushed to insert the base fabric that needs to be trimmed into the inside of the guide port. The excess base fabric is trimmed by the rotation of the cloth cutting saw blade. The "V" shape of the guide port can better guide the base fabric to the inside of the front guard to ensure that the base fabric can be accurately trimmed by the cloth cutting saw blade. At the same time, the protective cover, front guard, and side guards are used to protect the front, back, left, and right sides of the cloth cutting saw blade to ensure that the staff is safer during the process of trimming the base fabric, improving the safety of the entire device. It can be more flexible through manual operation by the staff, and can be used for trimming various special-shaped stretched fabrics, improving applicability. The device is compact and convenient as a whole, and can effectively improve the efficiency of trimming the base fabric.

[0014] 2. During use, when the staff pushes the machine by hand, the flat shape of the handle can provide a better grip, making the process more stable. At the same time, the anti-slip rubber sleeve increases the friction of the handle to ensure that the hand will not slip during the gripping process, thereby improving the safety of the staff. The reserved hole for the harness can better control the power cord and ensure that the power cord is at the rear end of the handle to prevent the power cord from being cut during the bottom fabric trimming work, thereby improving the safety of the bottom fabric trimming work. The drive motor can be disassembled by removing the bolts, which facilitates later repairs and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] During use, the staff fixes the cloth-cutting saw blade 5 to the output end of the driving motor 3 through the shaft locking mechanism 4, and inserts the front guard 6 into the front end of the guard 1, and ensures that the front guard 6 will not deviate after insertion through the cooperation of the limit groove 12 and the limit pin 11. At this time, the staff can press the front ends of the two cloth-cutting saw blades 5 to move closer to each other, and the barb block 13 will be clamped inside the barb clamping hole 14, so as to clamp the side guard 10 and the front guard 6 together, ensuring that the cloth-cutting saw blade 5 will not fall off during the process of cutting the bottom cloth;

[0023] When everything is ready, the staff starts the drive motor 3, and the output end of the drive motor 3 drives the cloth cutting saw blade 5 to rotate. The staff manually picks up the whole device and pulls the base fabric that needs to be trimmed upward, so that the base fabric that needs to be trimmed is in a stretched state. At this time, the whole device is pushed to insert the base fabric that needs to be trimmed into the inside of the guide port 7. The excess base fabric is trimmed by the rotation of the cloth cutting saw blade 5. The "V" shape of the guide port 7 can better guide the base fabric to the inside of the front guard 6 to ensure that the base fabric can be accurately trimmed by the cloth cutting saw blade 5. At the same time, the protective cover 1, the front guard 6, and the side guard 10 protect the front, back, left, and right sides of the cloth cutting saw blade 5 to ensure that the staff is safer in the process of trimming the base fabric, improve the safety of the whole device, and can be more flexible through manual operation by the staff. It can be applied to various special-shaped stretched fabrics for trimming, and improve applicability. The device is compact and convenient as a whole, and can effectively improve the efficiency of trimming the base fabric.
