Pushed by the push plate, the clamping frame moves onto the fixed frame, thus achieving automatic clamping frame replacement and greater efficiency.

Description

Technical Field

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

[0002] A quilting machine is a mechanical device used for weaving or sewing. It is mainly used to pass threads or bundles of threads through the holes or gaps in fabrics, textiles, or other materials to form intersections or connections, thereby completing the stitching, weaving, or sewing process. The clamping frame of the quilting machine is a device used to fix the workpiece to be quilted; it plays a role in clamping and stabilizing the workpiece during the quilting process to ensure the accuracy and quality of the quilting.

[0003] Currently, when quilting textiles with a quilting machine, the textiles must first be fixed to the clamping frame, which is then placed on the quilting machine frame. The quilting head then quilts the textiles. After quilting is completed, the operator needs to drag the clamping frame to the placement frame and move another set of textiles fixed to the clamping frame to the quilting machine frame for quilting. For a large number of quilting machines, this requires a large number of operators to assist in the operation, which is quite cumbersome and leads to a decrease in overall work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping frame moving mechanism for a quilting machine, which solves the problem of low efficiency in existing quilting machines where the clamping frame needs to be replaced by workers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping frame moving mechanism for a quilting machine, comprising a fixing component and a quilting machine head, a clamping frame disposed at the upper end of the fixing component, and a conveyor belt disposed at the lower end of the fixing component, wherein a feeding component is disposed on one side of the fixing component, and the fixing component includes:

[0006] A fixed frame is located at the lower end of the quilting machine head. A load-bearing plate is symmetrically and rotatably arranged on the inner side of the fixed frame. A drive component for driving the two sets of load-bearing plates to rotate is provided on one side of the fixed frame.

[0007] A baffle is slidably connected to one side of the fixed frame, and a first toothed rack is provided on one side of the baffle;

[0008] The feeding assembly includes:

[0009] A placement frame is provided on one side of the fixed frame;

[0010] An electric actuator is fixedly installed at the upper end of the placement frame, and a push plate is provided at the telescopic end of the electric actuator;

[0011] A connecting plate is rotatably mounted on one side of the placement frame. A connecting shaft is fixedly mounted on one side of the connecting plate. The connecting shaft extends rotatably to the outside of the placement frame and is provided with a push plate. A U-shaped connecting rod is provided at the upper end of the push plate. A second rack is provided on one side of the U-shaped connecting rod. The second rack meshes with a fourth gear. A third gear is also sleeved on the outside of the connecting shaft. The third gear meshes with a first rack.

[0012] Preferably, the lower end of the fixed frame is provided with a first leg, a mounting block is fixedly provided on one side of the first leg, and a connecting ring is provided on one side of the mounting block.

[0013] Preferably, the driving component includes a motor fixedly mounted on the upper end of the mounting block, a first gear mounted on the output shaft end of the motor, a transmission shaft rotatably connected inside the connecting ring, a second gear meshing with the first gear on the outer side of the transmission shaft, and second bevel gears symmetrically arranged at both ends of the transmission shaft.

[0014] Preferably, the lower end of the fixed frame is provided with a groove, and the two ends of the load-bearing plate are provided with a rotating shaft. The rotating shaft extends to the outside of the fixed frame and is provided with a first bevel gear, which meshes with a second bevel gear.

[0015] Preferably, one end of the fixed frame is provided with an L-shaped groove, an L-shaped slider is slidably disposed inside the L-shaped groove, the baffle is fixedly connected to the L-shaped slider, and one end of the L-shaped slider is fixedly connected to the first rack.

[0016] Preferably, a built-in cavity is provided on one side of the placement frame, and the third gear is located inside the built-in cavity.

[0017] Preferably, the lower end of the placement frame is provided with a second support leg, and the height of the placement frame is slightly higher than the height of the fixed frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention provides a clamping frame moving mechanism for a quilting machine. After the textile quilting on a set of clamping frames is completed, the two sets of load-bearing plates rotate in opposite directions under the drive of the drive component, allowing the upper clamping frame to fall onto the conveyor belt and be transported to the next process. After the load-bearing plates are reset, the push plate is moved by the electric push rod. Under the action of the second rack and fourth gear meshing and the first rack and third gear meshing, the connecting plate rotates to one side of the fixed frame and the baffle moves downward, allowing one end of the connecting plate to rotate to the upper end of the baffle. Under the push of the push plate, the clamping frame can move onto the fixed frame. Then, the push plate is retracted by the electric push rod, allowing the baffle and connecting plate to reset. This enables the quilting machine to automatically change the clamping frame, which is more convenient than manual disassembly and replacement by workers, and saves labor. When a large number of quilting machines are used simultaneously, a large number of workers are required to change the clamping frames at the same time, thus improving the working efficiency of a large number of quilting machines.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0031] Combination Figures 1-4 , Figures 6-8 The present invention discloses a clamping frame moving mechanism for a quilting machine, comprising a fixing component 1, a quilting machine head 2, a clamping frame 3 disposed on the upper end of the fixing component 1, and a conveyor belt 5 disposed on the lower end of the fixing component 1, wherein a feeding component 4 is disposed on one side of the fixing component 1, and the fixing component 1 includes:

[0032] A fixed frame 11 is located at the lower end of the quilting machine head 2. A load-bearing plate 13 is symmetrically and rotatably arranged on the inner side of the fixed frame 11. A drive component 14 for driving the two sets of load-bearing plates 13 to rotate is provided on one side of the fixed frame 11.

[0033] A baffle 15 is slidably connected to one side of the fixed frame 11, and a first rack 152 is provided on one side of the baffle 15;

[0034] The feeding component 4 includes:

[0035] Placement frame 41 is disposed on one side of the fixed frame 11;

[0036] An electric actuator 42 is fixedly installed on the upper end of the placement frame 41, and a push plate 43 is provided at the telescopic end of the electric actuator 42.

[0037] A connecting plate 44 is rotatably mounted on one side of the placement frame 41. A connecting shaft 441 is fixedly mounted on one side of the connecting plate 44. The connecting shaft 441 extends rotatably to the outside of the placement frame 41 and is provided with a push plate 43. A U-shaped connecting rod 431 is provided at the upper end of the push plate 43. A second rack 432 is provided on one side of the U-shaped connecting rod 431. The second rack 432 meshes with a fourth gear 443. A third gear 442 is also sleeved on the outside of the connecting shaft 441. The third gear 442 meshes with a first rack 152.

[0038] In this embodiment, the controller (not shown in the figure) controls the quilting machine head 2 to quilt the textile fixed by the clamping frame 3. After quilting is completed, the two sets of load-bearing plates 13 are rotated in opposite directions by the drive member 14, causing the clamping frame 3 at the upper end of the fixed frame 11 to fall to the upper end of the conveyor belt 5 and be transported by the conveyor belt 5 to the next process. At this time, the controller controls the drive member 14 to drive the two sets of load-bearing plates 13 back to the initial position. Then, the controller controls the electric push rod 42 to push the push plate 43 to one side of the fixed frame 11, so that the push plate 43 pushes the clamping frame 3 at the upper end of the placement frame 41 to move. While the push plate 43 is moving, it drives the second rack 432 to move to one side of the fixed frame 11 through the U-shaped connecting rod 431, so that the second rack 432 meshes and drives the fourth gear 443 to rotate. The fourth gear 443 drives the third gear 442 and the connecting plate 44 to rotate through the connecting shaft 441. The third gear 442 meshes and drives the first The rack 152 moves downward, and the first rack 152 drives the baffle 15 to move downward. When the connecting plate 44 rotates to the upper end of one side of the fixed frame 11, the teeth of the second rack 432 separate from the fourth gear 443. At this time, the fourth gear 443 stops rotating under the continuous push of the electric push rod 42, and the baffle 15 stops moving downward. The connecting plate 44 blocks the gap between the fixed frame 11 and the placement frame 41, and the clamping frame 3 moves to the upper end of the fixed frame 11 under the push of the push plate 43. When the clamping frame 3 is at the upper end of the fixed frame 11, the push plate 43 is reset by the electric push rod 42, so that the teeth of the second rack 432 re-mesh with the fourth gear 443, so that the fourth gear 443 drives the third gear 442 to rotate in the direction of rotation, thereby causing the first rack 152 to drive the baffle 15 to reset, so that the baffle 15 can block the clamping frame 3 and prevent it from deviating. At the same time, the connecting plate 44 is reset under the rotation of the fourth gear 443.

[0039] The present invention will be further described below with reference to embodiments.

[0040] Combination Figure 2 and Figure 3The lower end of the fixed frame 11 is provided with a first support leg 12. A mounting block 121 is fixedly provided on one side of the first support leg 12. A connecting ring 122 is provided on one side of the mounting block 121. The driving component 14 includes a motor 141 fixedly provided on the upper end of the mounting block 121, a first gear 142 installed on the output shaft end of the motor 141, a transmission shaft 143 rotatably connected inside the connecting ring 122, a second gear 144 meshing with the first gear 142 is provided on the outer side of the transmission shaft 143, and second bevel gears 145 are symmetrically provided at both ends of the transmission shaft 143.

[0041] In this embodiment, the motor 141 is started, and the motor 141 drives the first gear 142 to rotate. The first gear 142 meshes with and drives the second gear 144 to rotate. The rotation of the second gear 144 enables the transmission shaft 143 to rotate, and the rotation of the transmission shaft 143 drives the second bevel gears 145 at both ends of it to rotate.

[0042] Combination Figure 3 and Figure 5 The lower end of the fixed frame 11 is provided with a groove 111, and the two ends of the load-bearing plate 13 are provided with a rotating shaft 131. The rotating shaft 131 extends to the outside of the fixed frame 11 and is provided with a first bevel gear 132. The first bevel gear 132 meshes with a second bevel gear 145.

[0043] In this embodiment, the groove 111 prevents the load-bearing plate 13 from rotating to a position perpendicular to the ground, thus preventing damage caused by excessive rotation. Since the two sets of second bevel gears 145 mesh with the two sets of first bevel gears 132, and the transmission shaft 143 drives the second bevel gears 145 at both ends to rotate, the two sets of second bevel gears 145 mesh and drive the two sets of first bevel gears 132 to rotate. These two sets of second bevel gears 145 are symmetrically arranged, thus enabling them to mesh and drive the two sets of first bevel gears during rotation. 132 rotates in the opposite direction, and the two sets of first bevel gears 132 rotate in the opposite direction, driving the two sets of rotating shafts 131 to rotate in the opposite direction, thereby causing the two sets of load-bearing plates 13 to rotate in the opposite direction. Therefore, the clamping frame 3 at the upper end of the load-bearing plate 13 can gradually move down as the load-bearing plate 13 rotates. When the load-bearing plate 13 is perpendicular to the ground, the clamping frame 3 can fall to the upper end of the conveyor belt 5 and be transported by the conveyor belt 5 to the next process. This process is more convenient than the workers dragging the clamping frame 3, and also reduces labor costs.

[0044] Combination Figure 4 and Figure 5 An L-shaped groove 112 is provided at one end of the fixed frame 11. An L-shaped slider 151 is slidably arranged inside the L-shaped groove 112. The baffle 15 is fixedly connected to the L-shaped slider 151. One end of the L-shaped slider 151 is fixedly connected to the first rack 152.

[0045] In this embodiment, the push plate 43 is moved by the electric push rod 42, and at the same time, the second rack 432 is moved to one side of the fixed frame 11 by the U-shaped connecting rod 431. This causes the second rack 432 to mesh and drive the fourth gear 443 to rotate. The fourth gear 443 drives the third gear 442 and the connecting plate 44 to rotate simultaneously through the connecting shaft 441. When the third gear 442 rotates, it meshes and drives the first rack 152 to move downward. The first rack 152 drives the L-shaped slider 151 to slide downward inside the L-shaped groove 112. The L-shaped slider 151 drives the baffle 15 to move downward. When the teeth of the second rack 432 separate from the fourth gear 443, the fourth gear 443 stops rotating, and the third gear 442 stops rotating. This stops the first rack 152 from moving downward, and thus stops the L-shaped slider 151 and the baffle 15 from moving.

[0046] Combination Figure 6 The placement frame 41 has an internal cavity 411 on one side, the third gear 442 is located inside the internal cavity 411, the lower end of the placement frame 41 is provided with a second support leg 412, and the height of the placement frame 41 is slightly higher than the height of the fixed frame 11.

[0047] In this embodiment, the function of the built-in cavity 411 is to provide a position for the third gear 442 to rotate so that it does not collide with the placement frame 41 when it rotates. Since the height of the placement frame 41 is slightly higher than the height of the fixed frame 11, when the connecting plate 44 rotates to the upper end of the fixed frame 11, the connecting plate 44 and the placement frame 41 can remain parallel. Therefore, when the clamping frame 3 moves from the upper end of the placement frame 41 to the upper end of the fixed frame 11, it will not be blocked.

[0048] In summary: First, the quilting machine head 2 quilts the textile in the clamping frame 3 at the upper end of the fixed frame 11. After quilting is completed, the controller (not shown in the figure) controls the motor 141 to start. The motor 141 drives the first gear 142 to rotate, and the first gear 142 meshes with and drives the second gear 144 to rotate. Since the second gear 144 is fixedly connected to the transmission shaft 143, the rotation of the second gear 144 drives the transmission shaft 143 to rotate. The transmission shaft 143 drives the second bevel gears 145 at both ends to rotate. Because the two sets of second bevel gears 145 are symmetrically arranged, the meshing of the two sets of second bevel gears 145 drives the two sets of first bevel gears 132 to rotate in opposite directions, so that the two sets of first bevel gears 132 drive the two sets of rotating shafts 131 to rotate in opposite directions. The two sets of load-bearing plates 13 rotate in opposite directions, causing the clamping frame 3 at their upper ends to gradually move downwards. When the load-bearing plates 13 are perpendicular to the ground, the clamping frame 3 falls to the upper end of the conveyor belt 5, and the conveyor belt 5 transports the quilted textile to the next process. The motor 141 drives the first gear 142 to rotate in the opposite direction, causing the two sets of load-bearing plates 13 to reset. Then, the electric push rod 42 pushes the push plate 43 to one side of the fixed frame 11, causing the push plate 43 to push the clamping frame 3 at the upper end of the placement frame 41 to move. Simultaneously, the push plate 43, through the U-shaped connecting rod 431, drives the second rack 432 to one side of the fixed frame 11, causing the second rack 432 to mesh and drive the fourth gear 443 to rotate. 3. The connecting shaft 441 simultaneously drives the third gear 442 and the connecting plate 44 to rotate. The third gear 442 meshes and drives the first rack 152 to move downward. The first rack 152 drives the baffle 15 to move downward. When the connecting plate 44 rotates to the upper end of one side of the fixed frame 11, the teeth of the second rack 432 separate from the fourth gear 443. At this time, under the continuous push of the electric push rod 42, the fourth gear 443 stops rotating, and the third gear 442 stops rotating, so the first rack 152 stops moving downward. Therefore, the L-shaped slider 151 stops driving the baffle 15 to stop moving downward. At this time, one side of the fixed frame 11 is opened, and the connecting plate 44 connects the gap between the fixed frame 11 and the placement frame 41, so that the gap is blocked, and the electric push rod 44... 2. As the push plate 43 continues to move, it pushes the clamping frame 3 to the upper end of the fixed frame 11. Once the clamping frame 3 is at the upper end of the fixed frame 11, the push plate 43 is reset by the electric push rod 42. This causes the teeth of the second rack 432 to re-mesh with the fourth gear 443, which in turn drives the third gear 442 to rotate. This causes the first rack 152 to reset the baffle 15, preventing the clamping frame 3 from shifting during quilting. Simultaneously, the connecting plate 44 returns to its initial position as the fourth gear 443 rotates. This completes the automatic up-and-down movement of the clamping frame 3, compared to the manual dragging of the clamping frame 3 onto the placement rack.Moving another set of textiles, fixed to clamp 3, to the quilting machine frame for quilting further saves labor and improves work efficiency when multiple quilting machines are used simultaneously.
