Abstract
Description
Technical Field
[0001] The present application relates to the field of embroidery machines, and in particular to a multi-needle position cord embroidery shearing device for convenient threading. Background Art
[0002] Rope embroidery is a special embroidery technique. Different from traditional embroidery techniques, rope embroidery is unique in that it uses ropes instead of traditional silk threads, which gives the work a unique texture and visual effect. At the same time, rope embroidery is also different from ribbon embroidery. Although ribbon embroidery also uses ribbons as materials, its embroidery method and presentation effect are different from rope embroidery. Specifically, rope embroidery is completed by using a computerized rope embroidery machine to perform rope embroidery and other operations on the fabric. This process allows the selection of yarns or ropes of various materials, such as hemp rope, cotton rope, space-dyed big-belly yarn, etc., but the thickness of the rope should usually not be greater than 5 mm.
[0003] As a traditional handicraft, rope embroidery not only has practical value, but also carries rich cultural connotations and historical values. Through continuous innovation and development, it has formed a unique artistic style and characteristics, and has become an intangible cultural heritage with local characteristics. It has broad application prospects in the fields of home textile design and so on. However, in the traditional rope embroidery production process, for the shearing of rope embroidery thread, a method is usually adopted in which a hook hook hangs the rope embroidery thread close to a cutter and automatically cuts it off. In this rope embroidery thread cutting method, the hook hook needs to move a long distance, which leads to an increase in the stroke of the cylinder used to drive the crochet hook, and increases the overall size of the rope embroidery thread shearing structure, which is not conducive to the streamlined assembly control at the needle head of the embroidery machine. For this reason, the present application proposes a multi-needle position rope embroidery shearing device that is convenient for threading. Utility Model Content

[0008] Furthermore, a baffle is provided on the side wall of the hook knife close to one end of the hook ring, and the baffle is located on one side of the hook ring opening.
[0009] Furthermore, a guide groove is provided on the upper surface of the knife seat for the hook knife and the first rack to fit in and slide and translate.
[0010] Furthermore, the second rack is slidably fitted with the upper surface of the knife seat, and a buckle is provided on the movable sleeve of the second rack, and the buckle is fixed on the knife seat.
[0011] Furthermore, one end of the cutter facing the hook ring is tilted and bent toward the hook knife and is provided with a cutting edge, the cutting edge is in contact with the upper surface of the hook knife, and a pressing member for pressing the cutter downward is fixed on the knife seat.
[0012] Furthermore, the clamping member includes a fixing frame fixed on the knife holder, the fixing frame is a U-shaped structure, the two vertical arms of the fixing frame abut against the two sides of the cutter, a roller frame is slidably embedded in the fixing frame, a roller body is installed on the roller frame, and an adjusting bolt is threadedly penetrated on the top wall of the fixing frame, and the adjusting bolt is rotationally connected to the roller frame.
[0013] The beneficial effects of this application are:
[0014] By setting the driving structure and utilizing the symmetrical meshing of the first rack and the second rack with the driving gear, when the driving cylinder pushes the first rack to slide and translate, the cutting knife and the hook knife can be driven to translate in opposite directions. As a result, the driving cylinder is started to push the hook knife to slide away from the knife seat, and the hook ring at the end of the hook knife hooks the rope embroidery thread. The driving cylinder is started to contract, driving the hook knife to slide and translate toward the knife seat, and at the same time, the cutting knife will translate close to the hook ring, and then the cutting blade and the rope embroidery thread hooked by the hook ring will move toward each other, so the rope embroidery thread can be quickly cut off. Compared with the method of only relying on the hook ring to hook the rope embroidery thread close to the cutting blade for cutting, the structural method of moving the cutting blade and the rope embroidery thread hooked by the hook ring towards each other for shearing shortens the shearing stroke of the rope embroidery thread, and the rope embroidery thread is symmetrically stressed, thereby improving the smoothness of shearing.
