Description

Technical Field

[0001] This utility model belongs to the technical field of flower tying machines, and specifically relates to a flower tying machine. Background Technology

[0002] Tie-dyeing, also known as tie-dyeing, clamp-dyeing, and dyeing, is a traditional and unique folk dyeing technique in China, and one of the traditional hand-dyeing skills in China. The tie-dyeing process consists of two parts: tying the pattern and dyeing. Tying the pattern, originally called tying knots, involves selecting the fabric and then shaping it according to the pattern using methods such as gathering, folding, rolling, and squeezing. Then, the knots are sewn or tied tightly with needle and thread, creating a series of knots. The purpose of this is to prevent the tied parts from being dyed, allowing the tied parts to retain their original color while the untied parts are dyed evenly, thus creating uneven shades and rich layers of color and wrinkles. The tighter and more secure the fabric is tied, the better the dye-resistant effect.

[0003] According to patent number CN201110291955.3, a flower-tying machine includes a frame, a movable support, a left foot pedal, a right foot pedal, a motor, a pulley, a main drive wheel, a large-stroke gear, a small-stroke gear, a bearing box, a flower-tying winding box, a thread presser, a needle bar, a flower-tying head, and a pull rope. The motor is connected to the main drive wheel via the pulley. The main drive wheel drives the large-stroke gear, which in turn drives the small-stroke gear. The bearing box and the flower-tying winding box are connected to the small-stroke gear via a lead screw. The thread presser is connected to the flower-tying winding box.

[0004] The above-mentioned technical solutions still have some technical defects in actual use. Because the design and operation of the above solutions are purely mechanical structures and the design is relatively cumbersome, there are problems such as high failure rate, difficult maintenance, difficulty for novice operators, high noise, and complex operation. Moreover, in the current tie-dyeing process, it is still mainly done by hand, stitch by stitch, which has the following problems: First, it is difficult to make handicrafts with high degree of delicacy and strict standardization using the "hand tie-dyeing" method (hand tie-dyeing patterns are mostly rough and hazy); second, when "tie-dyeing" products are mass-produced, it is difficult to maintain the same quality in the same batch; third, the production efficiency of "tie-dyeing" products is low and affected by the busy agricultural season. Therefore, we propose a tie-dyeing machine. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution for a flower-tying machine: it includes a machine head 1, a tensioner 15, and a tensioner clamp 39. One end of the bottom of the outer casing 16 of the machine head 1 is movably connected to a winding box 14 via a bearing 27.

[0024] Specifically, a first servo motor 10 is fixedly mounted on one side of the outer side of the housing 16. The output shaft of the first servo motor 10 extends to the bottom side of the housing 16. A first synchronous pulley 8 is fixedly mounted on the output shaft of the first servo motor 10. A first synchronous belt 9 is provided between the first synchronous pulley 8 and the winding shaft synchronous pulley 25. The two inner ends of the first synchronous belt 9 are engaged with the winding shaft synchronous pulley 25 and the first synchronous pulley 8.

[0025] Specifically, a second servo motor 23 is fixedly mounted on the outside of the housing 16 near the first servo motor 10. A second synchronous pulley 22 is fixedly mounted at the end of the output shaft of the second servo motor 23. A rectangular slot is opened on one side of the top of the housing 16. The lead screw synchronous pulley 33 extends into the interior of the rectangular slot. The lead screw synchronous pulley 33 and the second synchronous pulley 22 are connected by a second synchronous belt 21.

[0026] Specifically, a tensioner 15 is provided on one side of the bottom of the winding box 14. The tensioner 15 consists of a tensioner screw 38, a tensioner clip 39, a tensioner spring 40, and a tensioner adjusting nut 41. The tensioner clip 39 and the tensioner spring 40 are sequentially sleeved on the outer periphery of the tensioner screw 38 and close to the end of the tensioner adjusting nut 41. The tensioner screw 38 extends into the interior of the winding box 14. A balancing 7 is installed on the outer bottom of the winding box 14 away from the tensioner 15. Wire box fixing pins 13 are provided on both sides of the top of the winding box 14.

[0027] Specifically, the top of the needle bar 32 extends to the top of the housing 16 and is fixedly installed with a needle bar adjustment handle 18. A needle bar locking handle 17 is installed in a notch on one side of the top of the housing 16. A hook force adjuster 19 is also installed on the top side of the housing 16 near the needle bar 32.

[0028] Specifically, machine position fixing seats 11 are fixedly installed on both sides of the bottom of the outer side of the housing 16, and angle fixing seats 12 are fixedly installed on the outer side of the housing 16 away from the second servo motor 23.

[0029] Specifically, the machine head 1 is mounted on the top of the frame 4 via the mounting bases 11 located on both sides of the bottom of the outer casing 16. A computer control box 2 is fixedly installed on the inner side of the middle of the frame 4, and a control foot pedal 3 is fixedly installed on the inner side of the bottom of the frame 4 near the machine head 1.

[0030] Specifically, a height adjuster 43 is installed at one end of the top of the frame 4 where the head 1 is mounted, and an angle adjuster 42 is provided at the connection point between the top of the height adjuster 43 and the head 1.

[0031] In this implementation plan, the tie-dye dots printed with the pattern on the tie-dye fabric are first placed under the tie-dye nozzle 6. Then, the control foot pedal 3 is pressed. By adopting a single-pedal design, the control foot pedal 3, in conjunction with the computer control box 2, realizes the microcomputer control function of the equipment. With the addition of an external display screen, the human-machine interaction function is realized. Different parameters can be modified to flexibly adjust different production processes. Compared with the mechanical control operation of the double-pedal, the single-pedal inching control operation uses electrical signals to send running instructions to the computer. The computer runs automatically according to real-time parameters. The power part uses a first servo motor 10 and a second servo motor 23 (both are driven by industrial servo motors), in conjunction with a photoelectric positioning plate 26, a first photoelectric switch 28, and a second photoelectric switch 31, which can accurately control the operation of the equipment. The operator does not need to frequently adjust the equipment, thereby improving production efficiency. The first servo motor 10, in conjunction with the first synchronous pulley 8 and the first synchronous belt 9, drives the winding shaft synchronous pulley 25 to rotate, which drives the ball spline shaft 29 and the winding box 14 to rotate synchronously. The servo motor 23, in conjunction with the second synchronous pulley 22 and the second synchronous belt 21, drives the lead screw synchronous pulley 33, enabling the lead screw 34 at the bottom to rotate. This drives the lead screw seat 30, thereby achieving vertical movement of the ball spline shaft 29. This facilitates the tying of the fabric according to different production processes. The tensioner 15, by rotating the tensioner adjusting nut 41, along with the tensioner clamp 39 and tensioner spring 40, drives the tensioner screw 38, thus achieving thread tightening. The purpose is to install the machine head 1 on the frame 4 using the height adjuster 43. The height adjuster 43 adjusts the height of the machine head 1 by adjusting the tightness of the fastening screws on the top shaft of the frame 4. The angle of the machine head 1 is adjusted by adjusting the tightness of the fastening screws on the angle adjuster 42 on the shaft of the height adjuster 43. The hook force adjuster 19 is connected to the hook bar 32 of the hook 5. By rotating, the built-in adjustable damping is adjusted, thereby adjusting the downward force of the hook bar 32.
