Description

Technical Field

[0001] This invention relates to the field of quilting machine technology, and in particular to a clamping frame moving mechanism for a quilting machine. Background Technology

[0002] Quilting allows the outer fabric of a quilt to be tightly fixed to the inner core, making the quilt even in thickness. It stitches the outer fabric and the inner core together in parallel straight lines or decorative patterns. A quilting machine is a textile machine used to sew linear patterns on the surface of mattresses, bedspreads, quilts, etc.

[0003] Existing quilting machines have structures such as a quilting machine frame, a clamping frame, and a quilting machine body. The mattress fabric to be quilted is fixedly clamped in the clamping frame, the clamping frame is placed on the quilting machine frame, and the fabric on the clamping frame is quilted by the equipment on the quilting machine body.

[0004] Currently, after a quilting machine finishes quilting a fabric, the operator needs to manually remove the clamping frame from the quilting machine frame and replace it with a new clamping frame before the next quilting cycle can begin. Current quilting machines cannot automatically replace the clamping frame, and manual replacement is time-consuming and labor-intensive. Therefore, we propose a clamping frame moving mechanism for quilting machines to solve the above problems. Summary of the Invention

The connecting lines pass through one end of a corresponding first track and one end of a corresponding third track. A slider is fixedly connected between the ends of two adjacent connecting lines. The slider is slidably connected within a first limiting groove. Two pulleys are rotatably connected to the slider, and the pulleys roll on the inner wall of the first limiting groove. A first rubber pad is fixedly connected to the slider, and second rubber pads are fixedly connected to the two side walls of the clamping frame. The first rubber pad and the second rubber pad are in close contact.

[0008] In one embodiment of the present invention, two fixing plates are fixedly connected to the bottom of the second fixing frame, and a second rotating shaft is rotatably connected between the two fixing plates through a bearing. External threads are provided on the surfaces of both ends of the second rotating shaft, and a crank handle is fixedly connected to both ends of the second rotating shaft. An L-shaped plate is threadedly connected to the second rotating shaft through the external threads, and the top end of the L-shaped plate is fixedly connected to the corresponding third track.

[0009] In one embodiment of the present invention, a first spring is fixedly connected to the top four corners of the second fixing frame, a receiving plate is fixedly connected to the top of the four first springs, and a fixing post is fixedly connected to the top four corners of the second fixing frame, the fixing post being located inside the corresponding first spring.

[0010] In one embodiment of the present invention, a first slot is provided in the slider, a second spring is fixedly connected to the top of the first slot, an arc-shaped block is fixedly connected to the bottom of the second spring, the bottom end of the arc-shaped block is in close contact with the bottom of the first limiting slot, and a sliding groove is provided at the bottom of both third limiting slots.

[0011] In one embodiment of the present invention The slider and the first rubber pad each have two second grooves inside. mouth A connecting rope is fixed to the top of the second slot, a counterweight is fixed to the bottom of the connecting rope, an inclined plate is fixed to the counterweight, the inclined plate extends out of the second slot, and impact rods are fixed to the two side walls of the counterweight.

[0012] In one embodiment of the present invention, two guide rods are fixedly connected to the second fixed frame, and a guide hole is provided on the L-shaped plate, through which the guide rod slides.

[0013] In one embodiment of the present invention, a support plate is fixedly connected to the top of the two third tracks, and a rotating column is rotatably connected to the support plate via a bearing. Multiple fan blades are fixedly connected to the bottom surface of the rotating column, and a gear is fixedly connected to the top of the rotating column. A connecting plate is threadedly connected to the surface of the guide rod, and a connecting rod is fixedly connected to the top of the connecting plate. A rack is fixedly connected to one end of the connecting rod.

[0014] In one embodiment of the present invention, a circular plate is fixedly connected to the surface of the rotating column, and a torsion spring is fixedly connected between the circular plate and the support plate.

[0015] In one embodiment of the present invention, two first guide wheel frames are fixedly connected to the second fixed frame, and two second guide wheel frames are fixedly connected to the quilting machine body. Two guide wheels are installed on each of the first and second guide wheel frames. The guide wheels are used to change the direction of the connecting line. A circular hole is opened at one end of the two first tracks and one end of the two third tracks, and the connecting line passes through the circular hole.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] This invention, through the setting of a connecting line and a slider, allows the motor to be started when a new clamping frame needs to be replaced. The motor drives one of the first rotating shafts to rotate, which in turn drives the other first rotating shaft to rotate via a sprocket and chain. The two first rotating shafts rotating in the same direction allow the two winding wheels to simultaneously unload and retract the thread. This allows the slider to slide within the first limiting groove via the connecting line. The slider, through the first and second rubber pads, moves the clamping frame. The connecting line brings the clamping frame to the middle of the third limiting groove. Rotating the crank handle drives the second rotating shaft to rotate. The second rotating shaft, through the external threads on both sides, moves the L-shaped plates and the third track on both sides to the sides, causing the clamping frame to fall onto the receiving plate. Rotating the crank handle in the opposite direction resets the third tracks on both sides. Then, the new clamping frame is placed between the two third tracks. Finally, the motor drives the clamping frame to the first limiting groove, solving the problem that current quilting machines cannot automatically replace clamping frames.

[0018] This invention utilizes gears and racks. When the clamping frame needs to be clamped by the sliders on both sides, the gears mesh with the racks during the movement of the third tracks on both sides. The racks drive the gears to rotate, which in turn drives the rotating column and fan blades to rotate. The rotating column drives the circular plate and torsion spring to rotate, allowing the torsion spring to accumulate power. During the reset process of the two third tracks, the connecting plate rotates, and the connecting plate drives the rack to rotate via the connecting rod, causing the rack and gears to disengage. Under the action of the torsion spring, the fan blades suddenly rotate, generating a strong downward wind. This wind blows between the first and second rubber pads, removing impurities or lint and preventing slippage between them. Simultaneously, the wind can move the inclined plate, causing the counterweight to swing inward around the top of the connecting rope towards the slider. During the reset process of the counterweight, the impact rod strikes the first rubber pad, causing any attached impurities or lint to fall off. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] Reference Figures 1-9 As shown, a clamping frame moving mechanism for a quilting machine includes a quilting machine body 1. Two first tracks 2 are fixedly connected to the quilting machine body 1. First limiting grooves 3 are formed on the two first tracks 2. Clamping frames 4 are slidably connected within the two first limiting grooves 3. The clamping frames 4 are used to clamp and fix the item to be quilted. A first fixing frame 5 is fixedly connected to one end of the quilting machine body 1. Two vertical plates 6 are fixedly connected to the bottom of the first fixing frame 5. Two second tracks 7 are fixedly connected to the top of the first fixing frame 5. The second tracks 7 are fixedly connected to the corresponding first tracks 2. Second limiting grooves 8 are formed on the two second tracks 7. The second limiting groove 8 is connected to the corresponding first limiting groove 3. A second fixing frame 9 is provided on one side of the first fixing frame 5. Four support columns 10 are fixed to the bottom of the second fixing frame 9. Two third tracks 11 are provided above the second fixing frame 9. The two third tracks 11 are provided with third limiting grooves 12. The third limiting grooves 12 are connected to the corresponding second limiting grooves 8. The clamping frame 4 clamps and fixes the item to be quilted. The clamping frame 4 is located in the two first limiting grooves 3. The quilting machine body 1 can quilt the item in the clamping frame 4. The clamping frame 4 can slide in the first limiting groove 3, the second limiting groove 8 and the third limiting groove 12.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, two first rotating shafts 13 are rotatably connected between the two vertical plates 6 via bearings. Each of the two first rotating shafts 13 is fixedly connected to a sprocket 14. A chain 15 is provided on one side of one of the vertical plates 6, and the two sprockets 14 are connected via the chain 15. A support plate 16 is fixedly connected to one of the vertical plates 6, and a motor 17 is fixedly connected to the support plate 16. The output shaft of the motor 17 is fixedly connected to one end of one of the first rotating shafts 13. Two winding wheels 18 are fixedly connected to the surfaces of both first rotating shafts 13. Connecting lines 19 are wound and fixedly connected to the surfaces of the four winding wheels 18. The connecting lines 19 pass through one end of the corresponding first track 2 and one end of the corresponding third track 11. A slider 20 is fixedly connected between the ends of two adjacent connecting lines 19. The slider 20 is slidably connected within the first limiting groove 3. Two pulleys 21 are rotatably connected to the slider 20. The pulleys 21 are connected to the first limiting groove 3. The slider 20 rolls on the inner wall of the groove 3. A first rubber pad 22 is fixedly attached to the slider 20, and a second rubber pad 23 is fixedly attached to the two side walls of the clamping frame 4. The first rubber pad 22 and the second rubber pad 23 are in close contact. When the quilting of the item is completed, the item needs to be replaced, that is, the clamping frame 4 needs to be replaced. The motor 17 is started, and the motor 17 drives one of the first rotating shafts 13 to rotate. The first rotating shaft 13 drives the other first rotating shaft 13 to rotate through the sprocket 14 and the chain 15. The two first rotating shafts 13 rotate in the same direction. The two first rotating shafts 13 can simultaneously drive the winding wheel 18 to rotate in the same direction. The two adjacent winding wheels 18 simultaneously release the connecting line 19 and retract the connecting line 19. Thus, the slider 20 can be pulled to slide in the first limiting groove 3 through the connecting line 19. The slider 20 drives the clamping frame 4 to move through the first rubber pad 22 and the second rubber pad 23, and finally makes the clamping frame 4 stop in the third limiting groove 12.

[0033] Furthermore, such as Figure 4As shown, two fixing plates 24 are fixedly attached to the bottom of the second fixing frame 9. A second rotating shaft 25 is rotatably connected between the two fixing plates 24 via bearings. External threads 26 are provided on the surfaces of both ends of the second rotating shaft 25. A crank handle 27 is fixedly attached to both ends of the second rotating shaft 25. An L-shaped plate 28 is threadedly connected to the second rotating shaft 25 via the external threads 26. The top of the L-shaped plate 28 is fixedly connected to the corresponding third track 11. When the crank handle 27 is rotated, the crank handle 27 drives the second rotating shaft 25 to rotate. The second rotating shaft 25 drives the L-shaped plates 28 on both sides to move to both sides. The L-shaped plates 28 drive the third track 11 to move to both sides. The clamping frame 4 will disengage from the third limiting groove 12. When the crank handle 27 is rotated in the opposite direction, the third tracks 11 on both sides move towards the middle, so that the new clamping frame 4 can be placed on the two third tracks 11. Then, the crank handle 27 is rotated to clamp the clamping frame 4 through the slider 20. Finally, the clamping frame 4 is transported to the quilting machine body 1 by the motor 17 for quilting.

[0034] Furthermore, such as Figure 6 As shown, the top four corners of the second fixing frame 9 are fixed with first springs 29, the top ends of the four first springs 29 are fixed with receiving plates 30, and the top four corners of the second fixing frame 9 are fixed with fixing posts 31. The fixing posts 31 are located in the corresponding first springs 29. The clamping frame 4 will disengage from the third limiting groove 12 and fall onto the receiving plate 30 below. The first springs 29 play a buffering role.

[0035] Furthermore, such as Figure 8 As shown, the slider 20 has a first slot 32, the top of the first slot 32 is fixedly connected to a second spring 33, and the bottom of the second spring 33 is fixedly connected to an arc-shaped block 34. The bottom end of the arc-shaped block 34 is in close contact with the bottom of the first limiting slot 3. The bottom of the two third limiting slots 12 is provided with a sliding groove 54. After the slider 20 enters the third limiting slot 12, under the action of the second spring 33, the arc-shaped block 34 is inserted into the sliding groove 54. When the third track 11 moves to both sides, the arc-shaped block 34 and the sliding groove 54 can make the slider 20 follow the movement of the third track 11 and release the clamping frame 4.

[0036] Furthermore, such as Figure 8 As shown, Two second slots 35 are respectively opened inside the slider 20 and the first rubber pad 22. A connecting rope 36 is fixed to the top of the second slot 35, and a counterweight 37 is fixed to the bottom of the connecting rope 36. An inclined plate 38 is fixed to the counterweight 37 and extends out of the second slot 35. Impact rods 39 are fixed to the two side walls of the counterweight 37. Downward wind can blow towards the inclined plate 38, and the inclined plate 38 can make the counterweight 37 swing around the top of the connecting rope 36 toward the inside of the slider 20, so that the impact rods 39 can impact the first rubber pad 22. The impact generates vibration, which can cause impurities and lint with strong adhesion to fall off.

[0037] Furthermore, such as Figure 4 and Figure 5 As shown, two guide rods 52 are fixedly connected to the second fixed frame 9. The L-shaped plate 28 is provided with a guide hole 53. The guide rod 52 slides through the guide hole 53. During the movement of the third track 11, the L-shaped plate 28 slides on the surface of the guide rod 52 through the guide hole 53.

[0038] Furthermore, such as Figure 9 As shown, support plates 40 are fixed to the top of the two third tracks 11. Rotating columns 41 are rotatably connected to the support plates 40 via bearings. Multiple fan blades 42 are fixed to the bottom surface of the rotating columns 41, and a gear 43 is fixed to the top of the rotating columns 41. A connecting plate 44 is threaded onto the surface of the guide rod 52, and a connecting rod 45 is fixed to the top of the connecting plate 44. A rack 46 is fixed to one end of the connecting rod 45. During the movement of the third tracks 11 to both sides, the third tracks 11 drive the support plates... When the support plate 40 moves, the gear 43 meshes with the rack 46. The gear 43 drives the rotating column 41 and the fan blade 42 to rotate. After the new clamping frame 4 is placed on the third track 11, the connecting plate 44 is rotated so that the rack 46 and the gear 43 do not mesh. The fan blade 42 rotates rapidly in the opposite direction. The fan blade 42 can generate a downward wind. The wind can blow away the lint and impurities attached to the first rubber pad 22 and the second rubber pad 23, preventing the lint and impurities from affecting the friction between the first rubber pad 22 and the second rubber pad 23.

[0039] Furthermore, such as Figure 9 As shown, a circular plate 47 is fixedly connected to the surface of the rotating column 41, and a torsion spring 48 is fixedly connected between the circular plate 47 and the support plate 40. The rotation of the rotating column 41 can cause the torsion spring 48 to rotate, so that the torsion spring 48 accumulates force. The rack 46 and the gear 43 do not mesh. Under the action of the torsion spring 48, the fan blade 42 rotates rapidly in the opposite direction.

[0040] Furthermore, such as Figure 2 and Figure 6 As shown, two first guide wheel frames 49 are fixedly connected to the second fixed frame 9, and two second guide wheel frames 50 are fixedly connected to the quilting machine body 1. Two guide wheels are installed on each of the first guide wheel frames 49 and the second guide wheel frames 50. The guide wheels are used to change the direction of the connecting line 19. A round hole 51 is opened at one end of each of the two first tracks 2 and one end of each of the two third tracks 11. The connecting line 19 passes through the round hole 51. The first guide wheel frames 49 and the second guide wheel frames 50 can change the direction of the connecting line 19 so that the two connecting lines 19 can pull the slider 20.

[0041] Working principle: During use, the clamping frame 4 clamps and fixes the item to be quilted. The clamping frame 4 is located in the two first limiting grooves 3. The quilting machine body 1 can quilt the item in the clamping frame 4. After the item is quilted, it needs to be replaced, that is, the clamping frame 4 needs to be replaced. Start the motor 17. The motor 17 drives one of the first rotating shafts 13 to rotate. The first rotating shaft 13 drives the other first rotating shaft 13 to rotate through the sprocket 14 and the chain 15. The two first rotating shafts 13 rotate in the same direction. The two first rotating shafts 13 can simultaneously drive the winding wheel 18 to rotate in the same direction. The two adjacent winding wheels 18 simultaneously release the connecting line 19 and retract the connecting line 19, thereby allowing the connecting line to be quilted. Pulling the slider 20 through the connecting line 19 causes it to slide within the first limiting groove 3. The slider 20, via the first rubber pad 22 and the second rubber pad 23, drives the clamping frame 4 to move, eventually stopping the clamping frame 4 within the third limiting groove 12. Turning the crank handle 27 causes the second rotating shaft 25 to rotate, which in turn causes the L-shaped plates 28 on both sides to move to the sides. The L-shaped plates 28 then cause the third track 11 to move to the sides, causing the clamping frame 4 to detach from the third limiting groove 12 and fall onto the receiving plate 30 below. The first spring 29 acts as a buffer. Turning the crank handle 27 in the opposite direction causes the third tracks 11 on both sides to move towards the center, allowing a new clamping frame 4 to be placed on the two third tracks 11. Then, rotate... The crank handle 27 clamps the clamping frame 4 via the slider 20. Finally, the motor 17 transports the clamping frame 4 to the quilting machine body 1 for quilting. After the slider 20 enters the third limiting groove 12, under the action of the second spring 33, the arc-shaped block 34 is inserted into the slide groove 54. When the third track 11 moves to both sides, the arc-shaped block 34 and the slide groove 54 can make the slider 20 follow the movement of the third track 11, releasing the clamping frame 4. During the movement of the third track 11 to both sides, the third track 11 drives the support plate 40 to move. The support plate 40 causes the gear 43 to mesh with the rack 46. The gear 43 drives the rotating column 41 and the fan blade 42 to rotate. The rotation of the rotating column 41 can cause the torsion spring 48 to rotate, allowing the torsion spring 48 to accumulate force. After placing the new clamping frame 4 on the third track 11, rotate the connecting plate 44 so that the rack 46 and gear 43 are not meshed. Under the action of the torsion spring 48, the fan blade 42 rotates rapidly in the opposite direction. The fan blade 42 can generate a downward wind, which can blow away the lint and impurities attached to the first rubber pad 22 and the second rubber pad 23, preventing the lint and impurities from affecting the friction between the first rubber pad 22 and the second rubber pad 23. The downward wind can blow towards the inclined plate 38, which can make the counterweight 37 swing around the top of the connecting rope 36 towards the inside of the slider 20, so that the impact rod 39 can impact the first rubber pad 22. The impact generates vibration, which can make the strongly attached impurities and lint fall off.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
