Description

Technical Field

[0001] The utility model relates to the technical field of quilting machines, in particular to a double-head quilting mechanism of a quilting machine. Background Art

[0002] A quilting machine is a textile machine used to sew linear patterns on the surfaces of mattresses, bedspreads, quilts, etc. Quilting is the process of sewing interlayered textiles with long needles to fix the cotton wool inside. After the quilt is filled with cotton wool, a quilting machine is needed to sew the outer fabric and cotton wool according to the pattern to fix the cotton wool.

[0003] Most of the traditional quilting machines only have one head to work. Quilts are of different sizes. When only one head is working, it is difficult to deal with quilts with larger areas or multiple rows of the same pattern, as the patterns need to be symmetrical and even. Using a single head has a slow movement speed and takes a long time, which seriously affects production efficiency.

[0004] Based on this, in order to solve the above-mentioned technical defects, a double-head quilting mechanism of a quilting machine is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a double-head quilting mechanism of a quilting machine.

[0006] A double-head quilting mechanism of a quilting machine includes a support frame, a fixing component, a slider, an electric box, a connecting plate, an electric slide rail 1, a sliding block, a quilting machine, a curved back needle, an electric slide rail 2, a controller, a thread locking component and an oil storage component. A fixing component for fixing a quilt is provided on the top of the support frame, and an electric slide rail 2 is symmetrically installed on the support frame. The electric slide rail 2 is slidably connected with sliders, and the tops of the sliders are connected to an electric box. A connecting plate is connected between the upper sides of the two electric boxes, and an electric slide rail 1 is symmetrically installed on the connecting plate. Sliding blocks are slidably connected between the front sides and the rear sides of the two electric slide rails 1.

A controller is installed on the left wall of the support frame, and the electric slide rail 2, the electric slide rail 1 and the quilting machine are electrically connected to the controller. A thread locking component is provided on the slider, and an oil storage component is provided on the thread locking component.

[0007] Furthermore, the fixing assembly includes a support frame, a fixing plate and a clip. The support frame is placed on the top of the support frame, two fixing plates are connected to the left side of the support frame, the two fixing plates are fixed to the support frame by pins, and clips for clamping the quilt are evenly installed on the outside of the support frame.

[0008] Furthermore, the thread locking assembly includes a rotary hook, a limit block and a U-shaped frame. The limit block is connected between the two sliders. The rotary hook is symmetrically slidably connected to the limit block. The U-shaped frame is connected between the rotary hook and the sliding block on the same side.

[0009] Furthermore, the rotary shuttle and the quilting machine are symmetrical up and down. When the curved back needle is sewing the quilt, it will be inserted into the rotary shuttle, and the thread on the locking thread structure in the rotary shuttle will intersect with the thread on the curved back needle.

[0010] Furthermore, the oil storage assembly includes an oil storage tank, an oil delivery pipe and a pumping pump.

[0024] like Figure 1 As shown, the fixing assembly includes a support frame 2, a fixing plate 3 and a clip 4. The support frame 2 is placed on the top of the support frame 1, and two fixing plates 3 are connected to the left side of the support frame 2. The two fixing plates 3 are fixed to the support frame 2 by pins, and clips 4 for clamping the quilt are evenly installed on the outside of the support frame 2 at intervals.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the thread locking assembly includes a rotary shuttle 15, a limit block 16 and a U-shaped frame 18. The limit block 16 is connected between the two sliders 5. The rotary shuttle 15 is symmetrically slidably connected to the limit block 16 in the front and back directions. The rotary shuttle 15 and the quilting device 10 are symmetrical up and down. When the curved back needle 12 sews the quilt, it will pass into the rotary shuttle 15. The thread on the thread locking structure in the rotary shuttle 15 will intersect with the thread on the curved back needle 12. The U-shaped frame 18 is connected between the rotary shuttle 15 and the sliding block 9 on the same side, and the rotary shuttle 15 and the quilting device 10 will move synchronously.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the oil storage assembly includes an oil storage tank 20, an oil delivery pipe 22 and a pumping pump 23. The lower side of the rotary hook 15 is equipped with an oil storage tank 20 containing oil. The rotary hook 15 and the oil storage tank 20 on the same side are connected with an oil delivery pipe 22. The oil delivery pipe 22 is equipped with a pumping pump 23.

The top of the sliding block 9 is welded with a support rod 13 for supporting the thread drum, and the top of the sliding block 9 is located on the left side of the support rod 13 and is connected to a T-shaped frame 14 for limiting the line.

[0028] When sewing the quilt, first remove the support frame 2, fix the four sides of the quilt on the support frame 2 by means of clips 4, then place the support frame 2 on the top of the support frame 1, and use a latch to fix the fixing plate 3 to the support frame 1 to stabilize the quilt. After the quilt is fixed, the thread spool to be used can be put on the support rod 13, and the tail end of the thread can be passed around the support rod 13. The support rod 13 is limited and the tail end of the thread is wound around the curved back needle 12. The sewing pattern and the line are transmitted to the controller 19 through the program, and the settings are made on the controller 19. The controller 19 then operates the electric slide rail 1 8 and the electric slide rail 2 17 according to the settings. The operation of the electric slide rail 17 can drive the slider 5 to move to the left or right, and the slider 5 will drive the electric box 6, the connecting plate 7, the sliding block 9, the quilting device 10 and the curved back needle 12 to move, and then the limit block 16 and the U-shaped frame 18 drive the rotary hook 15 to move, and the oil storage assembly will also move, and the operation of the electric slide rail 18 can drive the sliding block 9 and the quilting device 10 to move forward or backward, and then drive the U-shaped frame 18 to move, and the U-shaped frame 18 will drive the rotary hook 15 to move forward or backward along the limit block 16, and the U-shaped frame 18 will not affect the movement of the rotary hook 15, so the controller 19 will move according to the needs. The pattern to be sewn controls the rotary shuttle 15 and the quilting machine 10 to move synchronously, and controls the start and opening of the quilting machine 10. The presser foot 11 will press the surface of the quilt. When the quilting machine 10 works to control the curved back needle 12 to move the thread down through the quilt, the curved back needle 12 will penetrate into the rotary shuttle 15, intersect with the thread of the thread locking structure in the rotary shuttle 15, and bring out the thread in the thread locking structure, and sew it on the bottom surface of the quilt, playing a role in coordinating sewing. The quilting machine 10 and the rotary shuttle 15 will move synchronously to complete the positioning stitching of the quilt. The double heads are used to improve the overall work efficiency. After the stitching is completed, the controller 19 will control the electric slide 1 8 and the electric slide 2 1 7 is paused, and the staff can fix and cut the tail line. After finishing, operate the controller 19 to reset and close the electric slide rail 1 8 and the electric slide rail 2 17, and then remove the pin that fixes the fixing plate 3, remove the support frame 2, and disassemble the quilt on the support frame 2. In this way, the sewing work of the quilt is completed. When the internal rolling structure of the rotary hook 15 makes noise during use, the controller 19 can be operated to start the pumping pump 23, and the oil in the oil storage tank 20 can be sent into the rotary hook 15 through the oil delivery pipe 22 to lubricate the internal rolling structure of the rotary hook 15 to ensure smooth output of the line. After completion, the pumping pump 23 can be turned off.
