Description

Technical Field

[0001] This invention relates to the field of quilting machine technology, and more particularly to an automatic thread-cutting roller quilting machine. Background Technology

[0002] Quilting machines are commonly used quilting equipment and are widely used in the home textile industry, such as mattresses, bedspreads, and quilts. Roller quilting machines require the textiles to be fixed on the rollers for quilting during operation.

[0003] A search revealed that Chinese Patent Publication No. CN218621323U discloses a roller quilting machine for mattress cover production, comprising a support platform, with first fixing plates fixedly connected to both sides of the upper surface of the support platform. An unwinding mechanism and a rewinding mechanism are respectively arranged on the upper sides of the two first fixing plates. A feeding mechanism is located below the unwinding and rewinding mechanisms on the upper side of the support platform. A second fixing plate is fixedly connected to the middle of the upper side of the support platform. A guide sleeve arranged along the width direction of the support platform is fixedly connected to the upper end of the second fixing plate. A quilting head is slidably connected to the lower side of the guide sleeve. A driving mechanism for driving the quilting head to slide is arranged inside the guide sleeve. Two guide rollers are located on both sides of the quilting head on the upper side of the support platform. A guiding mechanism for straightening the fabric is also provided on the upper side of the support platform, which can improve the guiding effect of the mattress cover, prevent deviation, and improve quilting accuracy.

[0004] The above technical solution has the following disadvantages when used: When in use, the fabric remains in a loose state during quilting, lacking a mechanism to fix the fabric in place. As a result, the fabric is prone to shifting during quilting, affecting the quilting accuracy. When quilting, the surface of the fabric may have wrinkles. The lack of the ability to stretch and flatten the fabric makes it easy for wrinkles to appear on the surface when quilted, and there will be overlapping parts at the quilting point, thus affecting the quilting quality of the fabric. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an automatic thread-cutting roller quilting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic thread-cutting roller quilting machine includes: frame; A lifting movable frame slides through the top of the frame. A fixed plate is fixedly installed inside the frame, and an electric push rod for driving the lifting movable frame to rise and fall is fixedly installed at the bottom of the fixed plate. Flattening and positioning components are used to stretch and secure textiles; A movable quilting thread cutter assembly for quilting and cutting quilting threads onto textiles; A roller conveyor assembly for conveying textiles to a position below the flattening and positioning assembly; A movable support assembly for lifting the frame; Two cleaning components are symmetrically arranged on the top of the frame for cleaning dust from the surface of the textile fabric on the roller conveyor assembly.

[0007] Preferably, the leveling and positioning assembly includes two pairs of brackets fixedly installed on both sides of the lifting movable frame. A leveling roller is rotatably installed between each pair of brackets. A first motor for driving the corresponding leveling roller is fixedly installed on the surface of one of the brackets. Gears are coaxially fixedly installed on the ends of the two leveling rollers away from the first motor, and the two gears mesh with each other and are rotatably installed on the surface of the corresponding bracket.

[0008] Preferably, the movable quilting thread cutting assembly includes a lead screw rotatably mounted inside a lifting movable frame, a second motor for driving the lead screw is fixedly mounted on the outer side of the lifting movable frame, a movable block is threadedly connected to the top outer wall of the lead screw, an electric quilting head is fixedly mounted on the bottom of the movable block, and an electric telescopic rod is fixedly mounted on the side wall of the movable block, with an electric shearing blade fixedly mounted on the driving end of the electric telescopic rod.

[0009] Preferably, the roller conveying assembly includes multiple conveying rollers rotatably mounted in the frame, each conveying roller having a sprocket coaxially fixedly mounted at its end, the multiple sprockets being connected together by a chain, and a third motor for driving one of the conveying rollers being fixedly mounted on the outside of the frame.

[0010] Preferably, the movable support assembly includes multiple casters symmetrically fixedly installed at the bottom of the frame, and multiple support frames are slidably sleeved on the surface of the frame. A connecting plate is fixedly installed between each pair of adjacent support frames. A screw rod is threaded through the top of one of the connecting plates. A support plate is fixedly installed inside the frame, and a fourth motor for driving the screw rod is fixedly installed at the bottom of the support plate.

[0011] Preferably, the cleaning assembly includes a gate-shaped plate fixedly installed on the top of the frame, and a plurality of cleaning bristles are fixedly installed on the inner top of the gate-shaped plate, and the plurality of cleaning bristles are distributed in a linear array.

[0012] Preferably, a control panel is fixedly mounted on the surface of the frame, and the control panel is electrically connected to the first motor, the second motor, the third motor and the fourth motor.

[0013] Preferably, the top of the moving block slides against the inner top wall of the lifting moving frame.

[0014] Preferably, the size of each of the casters is smaller than the size of the support frame.

[0015] Compared with existing technologies, the advantages of the automatic thread-cutting roller quilting machine provided by this invention are as follows: 1. By controlling the electric push rod to push the lifting moving frame down, when the textile is conveyed to the bottom of the two flat rollers, the two flat rollers will come into contact with the textile, which can effectively position the textile and prevent it from shifting during quilting; 2. The first motor drives the flattening roller connected to it to rotate. Then, under the transmission of two meshing gears, the other flattening roller rotates in the opposite direction. That is, the two flattening rollers rotate in opposite directions to spread the textile out and flatten it, which can prevent the textile from becoming loose when quilting, thus ensuring the quality of quilting. 3. The second motor drives the lead screw to rotate, causing the moving block to move the electric quilting head. The electric quilting head can then perform quilting operations on the textile. After quilting is completed, the electric telescopic rod is controlled to drive the electric shearing blade to move down. When it is aligned with the quilting thread, the electric shearing blade can cut off the excess tail thread, achieving the effect of automatic thread cutting of the quilting thread. 4. The third motor controls the rotation of the connected conveyor rollers. Under the transmission between multiple sprockets and chains, each conveyor roller can rotate synchronously and in the same direction, automatically conveying textiles. This is convenient, fast, and helps improve the quilting efficiency of textiles. In summary, this invention, through two lifting and reversing rollers, can effectively position textiles to prevent them from shifting during quilting. It can also flatten the quilted areas of the textiles, preventing them from becoming loose during quilting and thus ensuring the quality of the quilting process. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Reference Figures 1 to 5 An automatic thread-cutting roller quilting machine includes: The frame 1 has a lifting movable frame 2 that slides through the top of the frame 1. A fixed plate 3 is fixedly installed inside the frame 1. An electric push rod 4 for driving the lifting movable frame 2 to lift is fixedly installed at the bottom of the fixed plate 3. The electric push rod 4 controls the lifting movable frame 2 to move in the vertical direction, thereby controlling the lifting movable frame 2 to perform lifting operations.

[0020] The flattening and positioning assembly is used to spread and fix the textile. The flattening and positioning assembly includes two pairs of brackets 5 respectively fixedly installed on both sides of the lifting moving frame 2. A flattening roller 6 is rotatably installed between each pair of brackets 5. A first motor 8 for driving the corresponding flattening roller 6 is fixedly installed on the surface of one of the brackets 5. Gears 7 are coaxially fixedly installed on the ends of the two flattening rollers 6 away from the first motor 8, and the two gears 7 mesh with each other. When the textile is conveyed to the bottom of the two flattening rollers 6, the electric push rod 4 is controlled to push the lifting moving frame 2 down until the two flattening rollers 6 contact the textile, which can effectively position the textile to prevent it from shifting during quilting. At the same time, the first motor 8 is started to drive the flattening roller 6 connected to it to rotate. Then, under the transmission of the two meshing gears 7, the other flattening roller 6 rotates in the opposite direction. That is, the two flattening rollers 6 rotate in opposite directions to spread and flatten the textile, which can prevent the textile from loosening during quilting, thereby ensuring the quilting quality.

[0021] A movable quilting thread cutter assembly is used to quilt quilting threads onto textiles and cut them. The movable quilting thread cutter assembly includes a lead screw 9 rotatably mounted inside a lifting movable frame 2. A second motor 10 for driving the lead screw 9 is fixedly mounted on the outside of the lifting movable frame 2. A movable block 11 is threadedly connected to the top outer wall of the lead screw 9. The top of the movable block 11 slides against the inner top wall of the lifting movable frame 2, which serves to limit the movement of the movable block 11, so as to ensure that the movable block 11 can move along the axial direction of the lead screw 9 under the limit of the lifting movable frame 2 when moving, and prevent the movable block 11 from rotating.

[0022] An electric quilting head 12 is fixedly installed at the bottom of the movable block 11, and an electric telescopic rod 13 is fixedly installed on the side wall of the movable block 11. An electric shearing blade 14 is fixedly installed at the drive end of the electric telescopic rod 13. During quilting, the electric quilting head 12 and the second motor 10 are started. The second motor 10 drives the lead screw 9 to rotate, causing the movable block 11 to move the electric quilting head 12. The electric quilting head 12 can then perform quilting operations on the textile. After quilting is completed, the electric telescopic rod 13 is controlled to drive the electric shearing blade 14 to move down. When it is aligned with the quilting thread, the electric shearing blade 14 can cut off the excess tail thread, achieving the effect of automatic thread cutting of the quilting thread.

[0023] The roller conveyor assembly is used to convey textiles to the area below the flattening and positioning assembly. The roller conveyor assembly includes multiple conveyor rollers 16 rotatably mounted in the frame 1. Each conveyor roller 16 has a sprocket 18 coaxially fixedly mounted at its end. A chain 19 is sleeved between the multiple sprockets 18. A third motor 17 for driving one of the conveyor rollers 16 is fixedly mounted on the outside of the frame 1. When conveying textiles, the third motor 17 is started to control the rotation of the conveyor roller 16 connected to it. At this time, under the transmission between the multiple sprockets 18 and the chain 19, each conveyor roller 16 can rotate synchronously and in the same direction, automatically conveying the textiles. This is convenient, fast, and helps to improve the quilting efficiency of textiles.

[0024] A movable support assembly is used to lift the frame 1. The movable support assembly includes multiple casters 20 symmetrically fixedly installed at the bottom of the frame 1, and multiple support frames 21 are slidably fitted on the surface of the frame 1. The size of each caster 20 is smaller than the size of the support frame 21. A connecting plate 22 is fixedly installed between each pair of adjacent support frames 21. A screw 23 is threaded through the top of one of the connecting plates 22. A support plate 24 is fixedly installed inside the frame 1. A fourth motor 25 for driving the screw 23 is fixedly installed at the bottom of the support plate 24. By controlling the rotation of the screw 23 through the fourth motor 25, the connecting plate 22 can drive each support frame 21 to move vertically along the surface of the frame 1. When moving upward, each caster 20 can be exposed, making it convenient for workers to push the device for transportation and transfer. When moving downward, each caster 20 can be lifted off the ground. At this time, the frame 1 can be supported by each support frame 21 to prevent the frame 1 from shifting position during operation and to ensure the operational stability of the device.

[0025] Two cleaning components are symmetrically arranged on the top of the frame 1 to clean the dust on the surface of the textile fabric on the roller conveyor assembly. The cleaning components include a gate-shaped plate 26 fixedly installed on the top of the frame 1. Multiple cleaning soft bristles 27 are fixedly installed on the inner top of the gate-shaped plate 26, and the multiple cleaning soft bristles 27 are distributed in a linear array. When the textile fabric is conveyed by the roller conveyor assembly, when its surface comes into contact with the cleaning soft bristles, the lint or dust can be automatically swept off.

[0026] Furthermore, a control panel 15 is fixedly mounted on the surface of the frame 1, and the control panel 15 is electrically connected to the first motor 8, the second motor 10 and the third motor 17. The first motor 8, the second motor 10 and the third motor 17 are all controlled by the control panel 15.

[0027] The working principle of this invention is as follows: In use, the textile to be quilted is placed on the conveyor roller 16, and then the third motor 17 connected to it is controlled by the control panel 15 to drive the conveyor roller 16 to rotate. At this time, under the transmission between multiple sprockets 18 and chains 19, each conveyor roller 16 can rotate synchronously and in the same direction to convey the textile. Then, when the quilted part of the textile is conveyed to the underside of the electric quilting head 12, the electric push rod 4 is controlled to push the lifting moving frame 2 down until the two flattening rollers 6 come into contact with the textile, which can effectively position the textile to prevent it from shifting during quilting. At the same time, the first motor 8 is started to drive the flattening roller 6 connected to it to rotate. Then, under the transmission of two meshing gears 7, the other flattening roller 6 rotates in the opposite direction. That is, the two flattening rollers 6 rotate in opposite directions to spread the textile flat. After the textile is flattened at the quilted seam, the electric quilting head 12 and the second motor 10 are started. The second motor 10 drives the lead screw 9 to rotate, causing the moving block 11 to move the electric quilting head 12. The electric quilting head 12 can then perform quilting operations on the textile. After quilting is completed, the electric telescopic rod 13 is controlled to drive the electric shearing blade 14 to move down. When it is aligned with the quilting thread, the electric shearing blade 14 can automatically cut off the excess tail thread.

[0028] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
