Description

Technical Field

[0001] This utility model relates to the field of quilting equipment technology, and more particularly to a quilting frame for a single-needle quilting machine. Background Technology

[0002] Traditional quilting machines have several clamps around the perimeter of the quilt frame. When using them, the textile needs to be manually clamped around the perimeter with the clamps. Each clamp needs to be operated individually, and the textile needs to be pulled while clamping to make it taut. This method is not only time-consuming and labor-intensive, but the manual pulling operation also results in uneven tension of the textile, causing many problems for the quilting process. Utility Model Content

[0003] The main purpose of this utility model is to provide a clamping frame for a single-needle quilting machine, so as to solve the problem that the clamping frames in the prior art require manual clamping and tightening one by one, which is time-consuming and laborious, and also easily leads to uneven tension of textiles.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: a clamping frame for a single-needle quilting machine, characterized in that it includes an outer frame, inner rods, and clamping components. The outer frame is square, and there are four inner rods arranged in a square shape inside the outer frame. The outer frame has two mutually perpendicular bidirectional threaded rods, which are staggered vertically. The two ends of each bidirectional threaded rod are rotatably connected to the corresponding side of the outer frame. The two sides of the bidirectional threaded rod along its length direction are respectively provided with threads in opposite directions. The two opposing inner rods share a single bidirectional threaded rod, and the two ends of each bidirectional threaded rod pass through the corresponding two inner rods and are threadedly connected to the corresponding two inner rods.

[0005] Each inner rod has a clamping assembly on its upper surface. The clamping assembly includes a lower clamp, an upper clamp, and a driving part. The lower clamp is fixedly installed on the upper surface of the inner rod, and the upper clamp is located above the lower clamp. The upper clamp and the lower clamp are respectively provided with an upper clamping head and a lower clamping head at their ends near the center of the outer frame. The driving part is located between the upper clamp and the lower clamp and clamps the upper clamping head and the lower clamping head. The surfaces of the upper clamping head and the lower clamping head are respectively provided with opposing wavy clamping parts.

[0006] As a further technical solution, the upper clamp has an upper clamp tail at the end away from the center of the outer frame, the bottom of the upper clamp tail has a first connecting end, and the top of the upper clamp tail has a second connecting end; the lower clamp has a lower clamp tail at the end away from the center of the outer frame, and a third connecting end is provided between the lower clamp head and the lower clamp tail; the first connecting end of the upper clamp is rotatably connected to the third connecting end of the lower clamp, and the second connecting end is rotatably connected to the driving part.

[0007] As a further technical solution, the driving unit includes a driving rod, a driving component, a pushing block, and a cylinder. A slide rail is provided on the lower clamp tail, and connecting plates are symmetrically arranged on both sides of the slide rail. The driving component is triangular, with a fourth connecting end, a fifth connecting end, and a sixth connecting end at its three vertices. The sixth connecting end is an elongated keyway. The pushing block is slidably disposed in the slide rail, with a connecting pin fixedly attached to one end of the pushing block, and its other end fixedly connected to the piston rod of the cylinder. The second connecting end of the upper clamp is rotatably connected to one end of the driving rod, the other end of the driving rod is rotatably connected to the fourth connecting end on the driving component, the fifth connecting end on the driving component is rotatably connected to the top of the connecting plate, and the connecting pin on the pushing block is slidably connected to the sixth connecting end.

[0008] As a further technical solution, one end of each of the two bidirectional threaded rods passes through the corresponding side of the outer frame, and a rotating handle is fixedly provided at its end.

[0009] As a further technical solution, each of the bidirectional threaded rods is symmetrically provided with a rotating shaft on both sides. The two ends of the rotating shaft are fixedly connected to the corresponding side of the outer frame, and the two ends of each rotating shaft pass through the corresponding inner rod and are slidably connected to the inner rod.

[0010] As a further technical solution, both the upper and lower clamps are designed to be elongated, and each inner rod is provided with multiple clamping components arranged along its length.

[0011] As a further technical solution, the surface of the clamping part is covered with a layer of silicone, and the silicone layer is provided with friction bumps.

[0012] The beneficial effects of this utility model are as follows: the clamping components on each side of this application can clamp uniformly without manual operation, which is convenient, quick, and saves time and effort. In addition, after clamping is completed, the two bidirectional threaded rods can be manually rotated to make the four inner rods drive the textile to tighten in both the horizontal and vertical directions, making the tension of the textile more uniform.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-2As shown, this utility model proposes a clamping frame for a single-needle quilting machine, including an outer frame 1, inner rods 2, and clamping components 7. The outer frame 1 is square, and there are four inner rods 2 arranged in a square pattern inside the outer frame 1, with each inner rod 2 corresponding to one side of the outer frame 1 and parallel to that side. The outer frame 1 has two mutually perpendicular bidirectional threaded rods 3, which are staggered vertically. The center intersection of the two bidirectional threaded rods 3 on the projection plane is the center of the outer frame 1. Both ends of each bidirectional threaded rod 3 are rotatably connected to the corresponding side of the outer frame 1, and the two sides of the bidirectional threaded rod 3 have threads in opposite directions. Two opposing inner rods 2 share a single bidirectional threaded rod 3, and both ends of each bidirectional threaded rod 3 pass through the corresponding two inner rods 2 and are threadedly connected to them. One end of each of the two bidirectional threaded rods 3 passes through the corresponding side of the outer frame 1, and a rotating handle 6 is fixedly provided at its end. Each bidirectional threaded rod 3 has symmetrically arranged rotating shafts 5 on both sides. The two ends of the rotating shafts 5 are fixedly connected to the corresponding sides of the outer frame 1, and the two ends of each rotating shaft 5 pass through the corresponding inner rod 2 and are slidably connected to the inner rod 2. In this application, each inner rod 2 has a connecting strip 4 at its bottom. The connecting strip 4 is connected to the bidirectional threaded rod 3 and the rotating shaft 5, respectively. The two bidirectional threaded rods 3 are staggered vertically, and the rotating shafts 5 corresponding to the two bidirectional threaded rods 3 are also staggered vertically.

[0023] like Figure 1 As shown, each inner rod 2 has a clamping assembly 7 on its upper surface. Figures 3-5As shown, the clamping assembly 7 includes a lower clamp 71, an upper clamp 70, and a driving unit. The lower clamp 71 is fixedly mounted on the upper surface of the inner rod 2, and the upper clamp 70 is located above the lower clamp 71. The upper clamp 70 and the lower clamp 71 are respectively provided with an upper clamp head 700 and a lower clamp head 712 at their ends near the center of the outer frame 1. The driving unit is located between the upper clamp 70 and the lower clamp 71 and drives the upper clamp head 700 to clamp the lower clamp head 712. The driving unit includes a driving rod 72, a driving component 73, a pushing block 74, and a cylinder 75. The upper clamp 70 is provided with an upper clamp tail 701 at its end away from the upper clamp head 700. The bottom of the upper clamp tail 701 is provided with a first connecting end 702, and its top is provided with a second connecting end 703. The lower clamp 71 has a lower clamp tail 713 at the end away from the lower clamp head 712. A third connecting end 714 is provided between the lower clamp head 712 and the lower clamp tail 713. A slide rail 715 is provided on the lower clamp tail 713, and connecting plates 716 are symmetrically provided on both sides of the slide rail 715. The drive member 73 has a triangular cross-section. A fourth connecting end 730, a fifth connecting end 731, and a sixth connecting end 732 are respectively provided at the three vertices of the drive member 73. The sixth connecting end 732 is an elongated keyway. The push block 74 is slidably disposed in the slide rail 715. A connecting pin 740 is fixedly provided at one end of the push block 74, and its other end is fixedly connected to the piston rod of the cylinder 75. The piston rod of the cylinder 75 is fixedly connected to the push block 74 and pushes the push block 74 to slide back and forth in the slide rail 715. The first connecting end 702 of the upper clamp 70 is rotatably connected to the third connecting end 714 on the lower clamp 71, the second connecting end 703 is rotatably connected to one end of the drive rod 72, the other end of the drive rod 72 is rotatably connected to the fourth connecting end 730 on the drive member 73, the fifth connecting end 731 on the drive member 73 is rotatably connected to the top of the connecting plate 716, and the connecting pin 740 on the push block 74 is slidably connected to the sixth connecting end 732.

[0024] Among them, such as Figure 3 As shown, the driving component 73 in this application consists of two symmetrical triangular bodies and an intermediate rod connecting the two bodies. The three vertices of each body are respectively a fourth connecting end 730, a fifth connecting end 731, and a sixth connecting end 732. A through groove is provided between the two bodies, through which the pushing block 74 can pass. Furthermore, connecting pins 740 are provided on both sides of the end of the driving component 73 closest to the pushing block 74, and these connecting pins 740 are slidably connected to the sixth connecting ends 732 on the two bodies. The corresponding ends of the driving rod 72 are rotatably connected to the fourth connecting ends 730 on the two bodies.

[0025] In this application, the piston rod of cylinder 75 pushes the pusher block 74 to move closer to the upper clamp 70, such as Figure 4As shown, the push block 74 drives the drive member 73 to rotate via the connecting pin 740, causing the fourth connecting end 730 on the drive member 73 to rotate upward. This causes the fourth connecting end 730 to drive the drive rod 72 to push the upper clamp 700 downward to press the lower clamp 712, thus clamping the textile between the upper clamp 700 and the lower clamp 712. Conversely, the cylinder 75 drives the push block 74 to move away from the upper clamp 700, causing the upper clamp 700 to rotate and separate from the lower clamp 712, thereby releasing the textile. Figure 5 As shown. Among them, as... Figure 3 and Figure 5 As shown, the surfaces of the upper clamp 700 and the lower clamp 712 are respectively provided with mutually cooperating wave-shaped clamping portions 76. Each clamping portion 76 has a recessed portion 760 and a protruding portion 761. The clamping portions 76 on the upper clamp 700 and the lower clamp 712 are arranged opposite to each other, so that when the upper clamp 700 and the lower clamp 712 are clamped, they can clamp the textile and prevent it from detaching. In addition, the surface of the clamping portion 76 is covered with a layer of silicone, which has friction protrusions to increase the friction force on the textile during clamping. Furthermore, the silicone layer is relatively soft, which can prevent damage to the textile.

[0026] In this application, both the upper clamp 700 and the lower clamp 712 are elongated, which increases the clamping area for textiles. Additionally, each inner rod 2 has multiple clamping components 7 arranged along its length, such as... Figure 1 As shown.

[0027] This application allows for the installation of a controller, with all cylinders 75 connected to it. Each inner rod 2 has a clamping assembly 7 forming a group, and the switching of each group of clamping assemblies 7 is individually controlled. In actual operation, all clamping assemblies 7 are first opened via the controller, and then the worker clamps the textile along its four edges sequentially. After clamping, the handle of the bidirectional threaded rod 3 is manually rotated, causing the two opposing inner rods 2 to move away from each other, thus tightening the textile in that direction. Then, the other bidirectional threaded rod 3 is rotated in the same way to tighten the textile in the other direction, achieving rapid tightening of the textile.

[0028] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
