Description

Technical Field

[0001] This utility model relates to the field of quilting and embroidery machine technology, and in particular to a multi-layer feeding device for quilting and embroidery machines. Background Technology

[0002] Existing quilting and embroidery machines use multiple layers of fabric for sewing, resulting in low pattern accuracy. To better meet customer requirements, existing quilting and embroidery machines have been equipped with multi-layer feeding devices, enabling multi-layer fabric sewing without wrinkles or deviation, and achieving high pattern accuracy.

[0003] Patent CN211420499U, entitled "Multi-layer Feeding Device for Quilting and Embroidery Machines," discloses a multi-layer feeding device for quilting and embroidery machines, including: a quilting and embroidery machine main unit, a feeding device, and a cotton feeding device. The feeding device includes: a left feeding bracket, a connecting plate, casters, bearing positioning components, a fabric winding shaft, a long shaft connector, a rotating shaft, a first connecting plate, a long connecting rod, a male transmission tenon, a female transmission tenon, a geared motor, a motor cover, a one-hole speed control box, and a right feeding bracket. The position of the fabric winding shaft in this patent cannot be flexibly adjusted, thus failing to meet the needs of fabric winding at different positions and with different tensions, resulting in insufficient applicability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-layer feeding device for quilting and embroidery machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-layer feeding device for a quilting and embroidery machine includes two feeding frames, with a connecting rod between the two feeding frames. The two ends of the connecting rod are respectively fixedly connected to the side walls of the two feeding frames. One end of each feeding frame is fixedly connected to a mounting plate, and the other end of each feeding frame is fixedly connected to a vertical rod. The lower end of each vertical rod is equipped with a moving wheel. Two fabric winding mechanisms are provided between the two vertical rods, and the two fabric winding mechanisms are arranged vertically.

[0007] As a further improvement of this utility model, the fabric rolling mechanism includes two sliding sleeves, which are slidably sleeved on two vertical rods respectively. Each of the two sliding sleeves has a locking structure on its side wall, and each of the two vertical rods has locking holes arranged on its side wall to cooperate with the locking structure. Each of the two sliding sleeves has a mounting base fixedly connected to its side wall, and each of the two mounting bases has a bearing fixedly embedded in it. A fabric rolling shaft is provided between the two mounting bases, and both ends of the fabric rolling shaft are respectively inserted into the inner side of the two bearings. A fixing frame is fixedly connected to the side wall of one of the mounting bases, and a motor is fixedly installed on the side wall of the fixing frame. The output shaft of the motor passes through the fixing frame and is fixedly connected to one end of the fabric rolling shaft.

[0008] As a further improvement of this utility model, the locking structure includes a locking rod that passes through the side wall of the sliding sleeve. The locking rod is slidably connected to the sliding sleeve. A pull rod is fixedly connected to the end of the locking rod. A tension spring is sleeved on the locking rod. One end of the tension spring is connected to the pull rod, and the other end of the tension spring is connected to the side wall of the sliding sleeve.

[0009] As a further improvement of this utility model, a diagonal rod is fixedly connected to the lower side wall of the feeding rack, and the end of the diagonal rod away from the feeding rack is fixedly connected to the side wall of the vertical rod.

[0010] As a further improvement of this utility model, four mounting holes are provided on the side wall of the mounting plate, and the four mounting holes are distributed in a rectangular structure.

[0011] As a further improvement of this utility model, the number of connecting rods is two.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a fabric rolling mechanism, the sliding sleeve can slide on the vertical rod, which can drive the fabric rolling shaft to move vertically, thereby adjusting the vertical position of the fabric rolling shaft to meet the needs of different positions and making it more versatile.

[0014] By setting a locking structure, the locking rod is inserted into the locking hole, and the tension of the spring acts on the locking rod, which can fix the sliding sleeve to the vertical rod, ensuring the stability of the sliding sleeve position, and making the adjustment of the sliding sleeve position convenient and quick.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A multi-layer feeding device for a quilting and embroidery machine includes two feeding racks 1, with a connecting rod 2 between the two feeding racks 1. The two ends of the connecting rod 2 are respectively fixedly connected to the side walls of the two feeding racks 1. There are two connecting rods 2. One end of the two feeding racks 1 is fixedly connected to a mounting plate 3. The side wall of the mounting plate 3 has four mounting holes 4, which are distributed in a rectangular structure. The other end of the two feeding racks 1 is fixedly connected to a vertical rod 6. The lower end of the two vertical rods 6 is equipped with a moving wheel 17. The lower side wall of the feeding rack 1 is fixedly connected to a diagonal rod 5. The end of the diagonal rod 5 away from the feeding rack 1 is fixedly connected to the side wall of the vertical rod 6. Two fabric rolling mechanisms are provided between the two vertical rods 6, and the two fabric rolling mechanisms are arranged vertically.

[0021] In this utility model, the fabric rolling mechanism includes two sliding sleeves 8, which are slidably sleeved on two vertical rods 6 respectively. Each of the two sliding sleeves 8 has a locking structure on its side wall, and each of the two vertical rods 6 has a locking hole 7 arranged on its side wall to cooperate with the locking structure. Each of the two sliding sleeves 8 has a mounting base 10 fixedly connected to its side wall, and each of the two mounting bases 10 has a bearing 11 fixedly embedded in it. A fabric rolling shaft 9 is provided between the two mounting bases 10, and both ends of the fabric rolling shaft 9 are respectively inserted into the inner side of the two bearings 11. A fixing frame 12 is fixedly connected to the side wall of one of the mounting bases 10, and a motor 13 is fixedly installed on the side wall of the fixing frame 12. The output shaft of the motor 13 passes through the fixing frame 12 and is fixedly connected to one end of the fabric rolling shaft 9.

[0022] The locking structure includes a locking rod 14 that runs through the side wall of the sliding sleeve 8. The locking rod 14 is slidably connected to the sliding sleeve 8. A pull rod 16 is fixedly connected to the end of the locking rod 14. A tension spring 15 is sleeved on the locking rod 14. One end of the tension spring 15 is connected to the pull rod 16, and the other end of the tension spring 15 is connected to the side wall of the sliding sleeve 8.

[0023] When using this utility model, if the position of the fabric roll shaft 9 needs to be adjusted, first operate the pull rod 16 to move the locking rod 14 outward so that the locking rod 14 moves out of the locking hole 7. Then move the sliding sleeve 8 to drive the fabric roll shaft 9 to move vertically and adjust the position of the fabric roll shaft 9. Then release the pull rod 16. Under the pulling force of the tension spring 15, the locking rod 14 is inserted into the locking hole 7, which can fix the position of the sliding sleeve 8, and thus fix the position of the fabric roll shaft 9.
