Description

Technical Field

[0001] The invention relates to the field of bow-knot generation, and in particular to a bow-knot tying device for textile and apparel design. Background Art

[0002] Bows are a widely used decorative item and are extremely popular among consumers, so they are widely used in packaging, clothing and other fields. However, due to the special way of tying bows, they can only be produced by hand or with manual assistance. The work efficiency is low, the product quality is inconsistent, and it is difficult to meet the mass production requirements of producers. Bow production equipment is needed to improve efficiency.

[0003] In the process of knotting, the traditional knotting method of current bow production equipment requires more operating steps and the method required is too complicated. There are three main power sources for bow production machines on the market: foot-operated type, which has simple equipment and requires manual pedaling for a long time, which can easily make people's legs tired and consumes a lot of energy. Long-term use will cause joint pain and strain; pure pneumatic and pure electric, which have stable equipment and high output. Workers do not need to repeatedly use force to pedal and are not easy to cause fatigue. However, unlike the foot-operated type, it cannot be used casually. Once it is used, it requires energy consumption. When tying knots for a small number of samples, it wastes resources and cannot be used conveniently, resulting in limited scope of application.

[0004] Therefore, we make improvements on this and propose a bow tying device for textile and clothing design. Summary of the invention

[0048] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0049] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0051] Example 1, please refer to Figure 7 , a bow-tying device for textile and apparel design, wherein the knotting member 200 comprises a pair of slide plates 201 with the outer ends extending out of the machine box 101 and in a horizontally staggered cross state, for details, please refer to Figure 1 The middle of the slide plate 201 is penetrated by a notch 202, and a pull rod 203 is provided in the notch 202 for limited sliding. The inner end of the pull rod 203 has an upward convex plate 204, and the connecting member 303 has a slot 3031 adapted to the convex plate 204. By separating the connecting member 303 from the knotting member 200, it is convenient to quickly replace the knotting member 200. The outer end of the pull rod 203 has a hook groove for hooking the belt body. There is a convex point in the middle part, and a linear groove is provided on the skateboard 201. The convex point is located in the linear groove to realize the limited sliding of the pull rod 203 and the skateboard 201. In the specific implementation, the pull rod 203 first pulls the belt body to move, and when the convex point contacts the inner wall of the linear groove, the pull rod 203 contacts the outer end of the skateboard 201 to limit the belt body, and the pull rod 203 continues to move to drive the skateboard 201 to move synchronously, and the knotting process of the bow is realized by the cooperation of the two knotting pieces 200.

[0052] For further information, please refer to Figure 1 A group of guide wheels 305 are provided on one side of the end of the slide bar 302, one end of the pull rope 307 is fixed on the top of the driving block 304, and the other end passes around the guide wheel 305 and is parallel to the slide bar 302. Through the setting of the guide wheel 305, when the pedal 301 is manually stepped on, the pull rope 307 moves more smoothly and labor-saving, which is conducive to improving the efficiency of bow tie production in the power-off state.

[0053] For further information, please refer to Figure 1 and Figure 4 and Figure 6 The bottom of the machine box 101 has an arc-shaped groove 102, and a rotating shaft 501 is arranged in the arc-shaped groove 102. The inner end of the connecting member 303 has a connecting plate inserted on the rotating shaft 501, and the top of the connecting plate has a sleeve sleeved on the slide rod 302, and the outer end of the sleeve has a downward protrusion, and the bottom of the protrusion is provided with a card groove 3031 adapted to the protrusion plate 204, and a reset spring 306 is arranged between the connecting plate and the inner wall of the arc-shaped groove 102. Through the setting of the reset spring 306, the pull rope 307 can be reset in the process of producing bows through the first driving mechanism 300 or the second driving mechanism 400, so that the two driving mechanisms are reset by the same power source, which is convenient for the two driving mechanisms to operate independently without interfering with each other, and convenient for the flexible use of the device.

[0054] For further information, please refer to Figure 5The rope pull member 403 is an L-shaped pull block, the outer end of the pull block is provided with a through hole 4031 coaxial with the pull rope 307, the inner end of the pull block is provided with a sliding sleeve 4032, both sides of the turntable 401 are installed with slide rails 405, the sliding sleeve 4032 is slidably embedded in the slide rail 405, and the connecting rod 404 is hinged between the sliding sleeve 4032 and the outer periphery of the turntable 401. Through the cooperation of the above structure, during the reversal of the turntable 401, the two pull rods 203 on both sides are synchronously belted with the sliding sleeves 4032 on both sides along the sliding rails The rail 405 makes linear motion, thereby driving the corresponding pull block to make linear motion, so that the pull ropes 307 on both sides are pulled inward, so that the driving block 304 drives the connecting piece 303 to drive the knotting piece 200 to run to realize the bow production process. It can be explained that the pull rope 307 is pulled inward by linear motion here, and the foot pedal 301 is fixedly installed on the frame 100, and the foot pedal 301 generally does not move upward, so in this process, only the driving block 304 moves along the slide rod 302.
