Description

Technical Field

[0001] This utility model relates to the textile field, and in particular to a movable cutting mechanism for a single-needle quilting machine. Background Technology

[0002] A quilting machine is a textile machine used to sew linear patterns onto the surfaces of mattresses, bedspreads, quilts, and other fabrics. Quilting machines used for quilting can be divided into two categories based on the number of stitches and the number of patterns they can sew: straight quilting machines and computerized quilting machines. Straight quilting machines typically come in 7-needle, 9-needle, and 11-needle configurations; these machines can only sew straight lines. Computerized quilting machines are single-needle designs and use a computer-controlled visual interface to move the machine and create patterns. When sewing patterns, a cutting device is needed to cut the fabric.

[0003] Existing cutting mechanisms are inconvenient for cutting. Currently, the two edge-cutting blades of a single-head quilting machine are installed in a separate cutting device. When quilting patterns on a single-head machine, the fabric and sponge must be tightened before quilting. After loosening the material and pulling it back to the cutting device, the pattern will be deformed, making it difficult for the edge-cutting blades to align with the edge line. The position and width need to be adjusted frequently, increasing the workload and reducing work efficiency. It is also inconvenient to replace the cutting blades. Generally, the cutting blades are installed and fixed to the output shaft of the motor with bolts. Disassembly and assembly require tools, which is cumbersome, increases workload, and reduces replacement efficiency. To solve the above problems, we propose a movable cutting mechanism for a single-needle quilting machine. Utility Model Content

[0004] The purpose of this invention is to provide a movable cutting mechanism for a single-needle quilting machine, which has the advantages of being easy to cut and easy to replace the cutting blade.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a movable cutting mechanism for a single-needle quilting machine, comprising a fixed beam, a slide rail bolted to the surface of the fixed beam, a slide block slidably connected to the surface of the slide rail, a transverse cylinder bolted to the surface of the slide block, one end of the transverse cylinder being bolted to the surface of the fixed beam, a movable machine head mounted on the surface of the fixed beam, and cutting mechanisms provided on the surface of the movable machine head and the bottom of the slide block, the cutting mechanism comprising a fixed plate, a blade holder mounted on the surface of the fixed plate, a motor mounted on the surface of the blade holder, a cutting blade provided at the output end of the motor, an up-and-down swing cylinder mounted between the blade holder and the fixed plate, and a first spring mounted between the blade holder and the fixed plate.

[0006] By adopting the above technical solution, two cutting mechanisms are installed on the fixed beam and the movable head respectively. After quilting, the fixed beam cutting blade is pushed to the right by the horizontal cylinder, and the movable head cutting blade moves to the right side of the head, aligns with the flower-shaped outer frame, and the up-and-down swing cylinder pushes the blade downward. The fixed beam moves backward to cut. Since the material is not loosened at this time, the cut edge is very flat, thereby facilitating cutting, reducing workload, and improving work efficiency.

[0007] The present invention is further configured such that: a fixed head is slidably sleeved on the inner wall of the motor output end, and the cutting blade is slidably sleeved on the fixed head; a rotating rod is rotatably sleeved on the inner wall of the fixed head; a connecting rod is hinged to the surface of the rotating rod; a snap-fit ​​connector is hinged to the other end of the connecting rod; a snap-fit ​​groove is provided on the inner wall of the motor output end, and the snap-fit ​​groove snaps into the snap-fit ​​connector; and a second spring is provided between the snap-fit ​​connector and the inner wall of the fixed head.

[0008] By adopting the above technical solution, rotating the rotating head causes the rotating rod to move the connecting rod. The movement of the connecting rod causes the snap-fit ​​connector to disengage from the snap-fit ​​hole, allowing the fixing head to be removed and the cutting blade to be replaced. This method facilitates the replacement of the cutting blade, reduces workload, and improves replacement efficiency.

[0009] The present invention is further configured such that a rotating head is bolted to one end of the rotating rod.

[0010] By adopting the above technical solution, a rotating head is provided to facilitate the rotation of the rotating rod.

[0011] The present invention is further configured such that: a positioning rod is bolted to the surface of the fixing head, and the positioning rod is engaged with the inner wall of the cutting blade.

[0012] By adopting the above technical solution, the fixed head is positioned by setting a positioning rod, which facilitates installation.

[0013] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0014] By adopting the above technical solution, one end of the connector is wedge-shaped, which facilitates the installation of the cutting blade.

[0015] The present invention is further configured such that: a protective cover is installed on the surface of the blade holder, and the cutting blade is located inside the protective cover.

[0016] By adopting the above technical solution, a protective cover is set up to protect the cutting blade.

[0017] The present invention is further configured such that a sharpener is mounted on the surface of the fixing plate.

[0018] By adopting the above technical solution, a sharpening device is set up to sharpen the cutting blade, ensuring the cutting effect.

[0019] The present invention is further configured such that a limit rod is bolted to the surface of the fixed beam.

[0020] By adopting the above technical solution, a limit rod is set to prevent the slide block from separating from the slide rail.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model installs two cutting mechanisms on a fixed beam and a movable head respectively. After quilting, the fixed beam cutting blade is pushed to the right by the horizontal cylinder, and the movable head cutting blade moves to the right side of the head, aligns with the flower-shaped outer frame, and the up-and-down swing cylinder pushes the blade downward. The fixed beam moves backward to cut. Since the material is not loosened at this time, the cut edge is very flat, thus achieving the purpose of easy cutting, reducing workload and improving work efficiency.

[0023] 2. This utility model achieves the purpose of conveniently replacing the cutting blade by rotating the rotating head to move the rotating rod and the connecting rod. The movement of the connecting rod causes the snap-fit ​​connector to disengage from the snap-fit ​​hole, allowing the fixing head to be removed and the cutting blade to be replaced. This reduces the workload and improves the efficiency of replacement. Attached Figure Description

The cutting mechanism 6 includes a fixed plate 7, a blade holder 8 mounted on the surface of the fixed plate 7, a motor 9 mounted on the surface of the blade holder 8, and a cutting blade 10 provided at the output end of the motor 9. A swing cylinder 11 is installed between the fixed plates 7, and a first spring 12 is installed between the knife holder 8 and the fixed plate 7. By installing the two cutting mechanisms 6 on the fixed beam 1 and the movable head 5 respectively, after quilting, the cutting blade of the fixed beam 1 is pushed to the right by the horizontal cylinder 4, and the cutting blade of the movable head 5 moves to the right side with the head, aligning with the flower-shaped outer frame. The swing cylinder 11 pushes the blade downward, and the fixed beam 1 moves backward to cut. Since the material is not loosened at this time, the cut edge is very flat, thereby facilitating cutting, reducing workload, and improving work efficiency.

The cutting mechanism 6 installed on the movable head 5 can move with the movable mechanism. When quilting the pattern, the fabric is first clamped and then pulled horizontally to perform normal quilting. After quilting, the cutting blade 10 on the fixed beam 1 is pushed to the right by the horizontal cylinder 4. The cutting blade 10 on the movable head 5 moves to the right side of the fixed beam 1 with the movable head 5, aligning with the outer frame of the fabric pattern. The two up-and-down swing cylinders 11 push the cutting blade 10 downward. The fixed beam 1 moves backward, and the cutting blade 10 cuts the fabric. Since the fabric is not loosened at this time, the cut edge is very flat. After cutting, the two cutting blades 10 are raised again. The cutting blade 10 on the fixed beam 1 is moved to the leftmost side by the horizontal cylinder 4, the clamping plate is released, and the fabric is pulled forward to proceed to the next process, thereby achieving the purpose of facilitating cutting.

[0043] Rotate the rotating head 19, which in turn drives the rotating rod 14 to rotate. The rotating rod 14 in turn drives the connecting rod 15 to move. The moving connecting rod 15 in turn drives the snap-fit ​​connector 16 to move. The snap-fit ​​connector 16 moves so that it disengages from the snap-fit ​​hole.
