Description

Technical Field

[0001] This utility model relates to the technical field of household textile processing equipment, specifically to a magnetic function nailing magnet device. Background Technology

[0002] Magnetic quilts have several permanent magnets evenly fixed inside the core. The magnetic field generated by these magnets provides certain health benefits.

[0003] In existing technology, magnets are typically encased in a resin shell. During installation, a sewing machine is generally used to sew the resin shell to the bedding fabric. The binding process involves first placing the magnet connected to the shell in the sewing position, then covering the magnet with the duvet cover, adjusting its position, lowering the pressure plate, and then starting the sewing machine. After sewing, the fabric-connected magnet is removed, a new magnet is placed, and the sewing process is repeated.

[0004] The placement of the magnets during the entire binding process is time-consuming. It's crucial to ensure the magnets don't obstruct the needle's work, and the needle's landing point isn't too far from the magnet. Furthermore, during sewing, the relative positions of the fabric, magnets, and needles need constant adjustment to guarantee sewing quality. However, the magnets' inherent magnetism easily attracts the worktable, making position adjustment difficult. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a magnetically functional nailed magnet device.

[0006] The technical solution of this utility model is:

[0007] A magnetically functional magnet-pinning device, comprising:

[0008] A sewing machine includes a worktable, a sewing head mounted on the top surface of the worktable, the sewing head being used for sewing fabric, and a pressing assembly located below the needle of the sewing head, the pressing assembly being connected to a drive assembly;

[0009] The pressing assembly includes a positioning plate for determining the position of the magnet, and a pressing plate is rotatably mounted on the positioning plate via a lifting plate for pressing the fabric.

[0010] The drive assembly includes a transmission plate, the bottom center of which is rotatably connected to the worktable via an eccentric assembly. The front end of the transmission plate is fixedly connected to a positioning plate. The rear end of the transmission plate is connected to a second power source via a second eccentric assembly. When the second power source is working, it can drive the transmission plate to perform circular motion via the eccentric assembly.

[0011] Preferably, the positioning plate has a positioning groove at the top front end for placing a magnet, and a through hole at the center of the positioning groove, the inner diameter of which is larger than the outer diameter of the magnet.

[0012] Preferably, the front end of the pressure plate is provided with sewing holes running vertically through it. The inner diameter of the sewing holes is larger than the outer diameter of the magnet, and the axis of the sewing holes coincides with the center line of the positioning groove.

[0013] Preferably, the maximum rotation angle of the lifting plate relative to the positioning plate is 90°, and the maximum rotation angle of the pressure plate relative to the lifting plate is 90°.

[0014] Preferably, a push-pull electromagnet is provided behind the lifting plate, and tension springs are provided on both sides of the push-pull electromagnet. The two ends of the tension springs are respectively connected to the lifting plate and the positioning plate.

[0015] Preferably, the eccentric component includes an intermediate turntable, on which a plurality of second adjustment holes are symmetrically provided, and the middle part of the transmission plate is rotatably connected to the second adjustment holes through a rotating pin.

[0016] Preferably, the second eccentric component includes an adjusting plate, the center of which is fixedly connected to the output shaft of the second power source, and a plurality of adjusting holes are symmetrically provided on the adjusting plate. The tail end of the transmission plate is rotatably connected to the adjusting holes through a rotating pin.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention reduces the difficulty and time of magnet positioning by setting up a pressing assembly and using a positioning plate to determine the position of the magnet. A push-pull electromagnet pushes the pressing plate downward to press the fabric and magnet, preventing the magnet from deviating during sewing. By setting up a driving assembly, a second power source works, and the cooperation of the eccentric assembly and the second eccentric assembly drives the transmission plate to make a circular motion around the center of the central turntable, which in turn drives the pressing assembly to make a circular motion, thereby causing the magnet and fabric to make a circular motion. This works in conjunction with the sewing machine to automatically sew the fabric and magnet together, improving efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0031] A magnetically functional magnet-pinning device, comprising:

[0032] Sewing machine 1 includes a worktable 11, with a machine head 12 mounted on the top surface of the worktable 11. The machine head 12 is used for sewing fabric. A pressing assembly 2 is provided below the needle of the machine head 12, and the pressing assembly 2 is connected to a drive assembly 3.

[0033] A first power source 13 is fixedly installed under the workbench 11 by screws, and the output shaft of the first power source 13 is connected to the input shaft of the machine head 12 through the belt drive assembly 14.

[0034] The first power source 13 can be an electric motor, which, when in operation, drives the sewing machine head 12 via the belt drive assembly 14. The sewing machine head 12 is a known sewing machine head.

[0035] The pressing assembly 2 includes a positioning plate 21, which is used to determine the position of the magnet. A pressing plate 23 is rotatably mounted on the positioning plate 21 via a lifting plate 25. The pressing plate 23 is used to press the fabric.

[0036] The positioning plate 21, lifting plate 25 and pressure plate 23 are all made of non-magnetic metal materials.

[0037] The top front end of the positioning plate 21 is provided with a positioning groove 22, which is used to place the magnet. The center of the positioning groove 22 is provided with a through hole, the inner diameter of which is larger than the outer diameter of the magnet.

[0038] After the magnet is placed in the positioning groove 22, the magnet is located in the center of the through hole, and the gap between the magnet and the through hole is used for the sewing machine needle to pass through.

[0039] The front end of the pressure plate 23 is provided with a sewing hole 24 running through it from top to bottom. The inner diameter of the sewing hole 24 is larger than the outer diameter of the magnet, and the axis of the sewing hole 24 coincides with the center line of the positioning groove 22.

[0040] After the pressure plate 23 presses down on the fabric, the fabric covers the magnet, and the magnet is located in the center of the sewing hole 24. The gap between the sewing hole 24 and the magnet is used for the sewing machine needle to pass through.

[0041] The maximum rotation angle of the lifting plate 25 relative to the positioning plate 21 is 90°, and the maximum rotation angle of the pressure plate 23 relative to the lifting plate 25 is 90°.

[0042] The lifting plate 25 can rotate within a range of 90° horizontally and vertically upward. The pressure plate 23 can only rotate relative to the lifting plate 25 within a range of 90° horizontally and vertically downward. When the lifting plate 25 is stationary, the pressure plate 23 cannot rotate upward, which facilitates pressing the fabric.

[0043] A push-pull electromagnet 27 is provided behind the lifting plate 25. Tension springs 26 are provided on both sides of the push-pull electromagnet 27. The two ends of the tension springs 26 are connected to the lifting plate 25 and the positioning plate 21, respectively.

[0044] The tension spring 26 is a helical spring. The elastic force of the tension spring 26 can drive the lifting plate 25 to rotate upward relative to the positioning plate 21, thereby driving the pressure plate 23 to move upward, and thus releasing the cloth and magnet.

[0045] The push-pull electromagnet 27 is fixedly installed on the top surface of the positioning plate 21 behind the lifting plate 25 by screws. The end of the movable rod of the push-pull electromagnet 27 is threaded with a ball head 28.

[0046] When the push-pull electromagnet 27 is energized, it can drive the ball head 28 to move towards the lifting plate 25, thereby pressing down the lifting plate 25, and then causing the pressure plate 23 to move downward and press onto the fabric.

[0047] After the push-pull electromagnet 27 is de-energized, the ball head 28 moves away from the lifting plate 25 and rotates upward under the elastic force of the tension spring 26.

[0048] The drive assembly 3 includes a transmission plate 36. The bottom center of the transmission plate 36 is rotatably connected to the worktable 11 through an eccentric assembly. The front end of the transmission plate 36 is fixedly connected to the positioning plate 21. The rear end of the transmission plate 36 is connected to a second power source 31 through a second eccentric assembly. When the second power source 31 is working, it can drive the transmission plate 36 to make circular motion through the eccentric assembly.

[0049] The tail end of the positioning plate 21 is fixedly connected to the transmission plate 36 by screws. When the transmission plate 36 makes a circular motion, the positioning plate 21 will move along with the transmission plate 36.

[0050] The eccentric assembly includes an intermediate turntable 34, on which several second adjustment holes 35 are symmetrically arranged. The middle part of the transmission plate 36 is rotatably connected to the second adjustment holes 35 through a rotating pin 37.

[0051] The intermediate turntable 34 is mounted on the rear side of the top surface of the worktable 11 via a rotating shaft. The distance from the rotating pin 37 to the center of the intermediate turntable 34 should be greater than the outer diameter of the magnet but less than the inner diameter of the sewing hole 24.

[0052] The second eccentric component includes an adjustment plate 32, the center of which is fixedly connected to the output shaft of the second power source 31. Several adjustment holes 33 are symmetrically provided on the adjustment plate 32, and the tail end of the transmission plate 36 is rotatably connected to the adjustment holes 33 through a rotating pin 37.

[0053] The second power source 31 adopts a servo motor. The second power source 31 is fixedly installed on the bottom surface of the workbench 11 by screws. The output shaft of the second power source 31 passes through the workbench 11 and is snapped into the adjustment plate 32.

[0054] The adjusting plate 32 is elongated, and the spacing and size of the adjusting holes 33 on the adjusting plate 32 are the same as the spacing and size of the second adjusting holes 35. The distance between the rotating pin 37 and the output shaft of the second power source 31 should be the same as the distance between the rotating pin 37 and the center of the intermediate turntable 34.

[0055] At the same time, the rotating pin 37 should be located on the same side of the output shaft of the second power source 31 and the center of the intermediate turntable 34.

[0056] When the second power source 31 is working, it can drive the adjusting plate 32 to rotate, thereby driving the tail of the transmission plate 36 to make a circular motion around the output shaft of the second power source 31, and then driving the intermediate turntable 34 to rotate through the transmission plate 36. Since the distance between the rotating pin 37 and the output shaft of the second power source 31 should be the same as the distance between the rotating pin 37 and the center of the intermediate turntable 34, the entire transmission plate 36 makes a circular motion around the center of the intermediate turntable 34, and thus the pressing assembly 2 also makes a circular motion.

[0057] In this embodiment, when using this equipment, the operator selects different pressing components 2 according to the size of the magnet, and fixes the positioning plate 21 and the transmission plate 36 with screws. At the same time, the position of the transmission plate 36 is adjusted so that the distance from the rotating pin 37 to the center of the intermediate turntable 34 is greater than the outer diameter of the magnet and less than the inner diameter of the sewing hole 24.

[0058] At the same time, it must be ensured that the distance between the rotating pin 37 and the output shaft of the second power source 31 is the same as the distance between the rotating pin 37 and the center of the intermediate turntable 34. Furthermore, the rotating pin 37 is located on the same side as the output shaft of the second power source 31 and the center of the intermediate turntable 34.

[0059] When the push-pull electromagnet 27 is de-energized, the ball head 28 moves away from the lifting plate 25 and rotates upward under the elastic force of the tension spring 26, thereby driving the pressure plate 23 to move upward.

[0060] Place the magnet into the positioning slot 22, cover it with the quilt cover to be sewn, and adjust the position of the quilt cover. Then energize the push-pull electromagnet 27. When the push-pull electromagnet 27 is energized, it can drive the ball head 28 to move towards the lifting plate 25, thereby pressing down the lifting plate 25, which in turn causes the pressure plate 23 to move downward and press onto the fabric.

[0061] Then, the second power source 31 is controlled to work, driving the pressing assembly 2 to perform circular motion. The radius of motion of the pressing assembly 2 is the same as the distance from the rotating pin 37 to the center of the intermediate turntable 34.

[0062] The circular motion of the pressing component 2 will cause the magnet and the fabric to move simultaneously. At this time, the control head 12 will work to sew the magnet and the fabric together.

[0063] The number of rotations of the output shaft of the second power source 31 is controlled according to the sewing requirements.

[0064] Then the second power source 31 and the machine head 12 can be controlled to stop working.

[0065] Then, the push-pull electromagnet 27 is de-energized, the ball head 28 moves away from the lifting plate 25, and rotates upward under the elastic force of the tension spring 26, thereby driving the pressure plate 23 to move upward, releasing the pressure on the fabric, and then inserting a new magnet to sew again.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
