Description

Technical Field

[0001] This application relates to the field of embroidery machines, and more particularly to a magnetic assembly for an embroidery frame of an embroidery machine. Background Technology

[0002] An embroidery machine is a machine used to embroider fabric. The embroidery frame of the embroidery machine is used to fix the fabric to be embroidered. The fabric can move with the embroidery frame. When the embroidery frame moves, the machine head can perform embroidery operations on the fabric. The embroidery frame is made of metal. When fixing the embroidered fabric, magnets are often used to attract the fabric to the embroidery frame, thereby fixing the fabric. Strong magnets are used to fix the fabric firmly. However, strong magnets have strong magnetic force. When the fabric is finished being embroidered and the strong magnet needs to be removed, it is easy for the strong magnet to move relative to the embroidery frame, scratching the fabric and causing damage. Utility Model Content

[0003] To reduce fabric scratches when removing strong magnets, this application provides a magnetic attachment assembly for embroidery frames of embroidery machines.

[0004] This application provides a magnetic suction component for an embroidery frame on an embroidery machine, which adopts the following technical solution: A magnetic suction assembly for an embroidery frame of an embroidery machine includes a mounting block, a magnet, a dial plate, and a mounting component. The mounting block has a mounting groove, and the mounting component is used to mount the magnet into the mounting groove. The dial plate is located on the side of the mounting block away from the magnet, and a gripping plate is provided on the dial plate. The gripping plate is located on the side wall of the dial plate, and the orthographic projection of the gripping plate is located outside the orthographic projection of the mounting block.

[0005] By adopting the above technical solution, magnets are used to fix the fabric to the embroidery frame. When the fabric needs to be removed from the embroidery frame, the worker can hold the holding plate. Since the orthographic projection of the holding plate is outside the orthographic projection of the mounting plate, the position of the holding plate forms a lever. The holding plate can lift the mounting block with the magnet installed, reducing the movement of the magnet relative to the embroidery frame and scratching the fabric. The magnet is installed through the mounting component. When the magnet is damaged, it can be replaced, improving the service life of the magnetic components.

[0006] Optionally, the mounting component includes a mounting bolt and a mounting nut. The magnet has a countersunk hole on the side away from the dial plate. The tail of the mounting bolt passes through the countersunk hole, the mounting block, and the dial plate in sequence. The head of the mounting bolt is located in the countersunk hole. The mounting nut is threaded onto the mounting bolt and abuts against the dial plate.

[0007] By adopting the above technical solution, the mounting bolt passes through the countersunk hole, the mounting block, and the dial plate, and the mounting nut is threadedly connected to the mounting bolt. The mounting bolt and the mounting nut integrate the magnet, the mounting block, and the dial plate into one unit, thereby improving the reliability of operating the magnet.

[0008] Optionally, the angle between the grip plate and the lever plate is an obtuse angle.

[0009] By adopting the above technical solution, the angle between the grip plate and the lever is obtuse, and the grip plate is tilted, which allows the wrist to be better maintained in a more neutral and relaxed posture; it reduces the bending angle of the wrist and improves the comfort of the operator.

[0010] Optionally, both the grip plate and the lever plate have chamfered edges.

[0011] By adopting the above technical solution, the grip plate and lever plate are parts that workers can easily come into contact with. By rounding the corners, the possibility of workers being scratched by the grip plate or lever plate is reduced.

[0012] Optionally, the mounting block is provided with a lifting assembly for reducing friction. The lifting assembly includes a lifting frame, two rotating rollers, and an adjusting component. The lifting frame is slidably connected to the mounting block along the direction from the mounting block to the lever plate. The two rotating rollers are located on both sides of the magnet and are rotatably connected to the lifting frame. The adjusting component is used to change the distance between the magnet and the embroidery frame.

[0013] By adopting the above technical solution, when the fabric is placed and needs to be fixed with magnets, the magnets move at a relatively fast speed during the magnetic attraction process. This high speed brings impact force, which can cause the originally placed fabric to shift and require adjustment. Since the contact area between the magnet and the embroidery frame is large, directly pulling the fabric may damage it. The staff can first move the lifting frame using the adjusting device so that the two rollers contact the embroidery frame and the magnets cannot contact the embroidery frame. At this time, the embroidery frame only contacts the rollers, and the fabric can be moved more easily. After the fabric is adjusted, the staff can then use the adjusting device to retract the rollers until the magnets fully contact the fabric.

[0014] Optionally, the adjusting component includes an adjusting screw and a rotating handle. The length direction of the adjusting screw is parallel to the sliding direction of the lifting frame. The adjusting screw is rotatably connected to the mounting block. The lifting frame is threadedly connected to the adjusting screw. The rotating handle is disposed on the adjusting screw.

[0015] By adopting the above technical solution, when the operator needs to adjust the position of the rotating roller, the operator can hold the rotating handle, which drives the adjusting screw to rotate. The adjusting screw drives the lifting frame to move, and the lifting frame drives the rotating roller to move until the rotating roller lifts the mounting block, so that the magnet is separated from the fabric. The adjusting component has a simple structure, and the screw has a self-locking effect, making the structure more reasonable.

[0016] Optionally, the adjusting screw passes through the dial plate, and the end of the adjusting screw is provided with a plug-in block. The rotating handle is provided with a plug-in groove, and the rotating handle is engaged with the plug-in block through the plug-in groove.

[0017] By adopting the above technical solution, the dial plate and the grip plate are metal plates. During the assembly of the magnet assembly, the dial plate is installed on the mounting block through the mounting parts. At this time, the adjusting screw passes through the dial plate, and finally the rotating handle is snapped into the plug block of the adjusting screw through the plug slot. This conforms to the installation structure sequence of the magnet assembly and is convenient for production and manufacturing.

[0018] Optionally, the grip plate is provided with grip grooves to reduce relative hand movement of the worker.

[0019] By adopting the above technical solution, when the magnet needs to be detached from the fabric, the worker can hold the gripping groove. The gripping groove increases the friction between the worker's hand and the gripping plate, thereby improving the reliability of the magnet detaching from the fabric.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The orthographic projection of the holding plate is located outside the orthographic projection of the mounting block. When it is necessary to remove the magnet from the fabric, the magnet can be lifted by bending the holding plate, which reduces the movement of the magnet relative to the fabric and ensures the quality of the fabric. 2. The lifting component detaches the magnet from the fabric, making it easier to adjust the fabric's position. Attached Figure Description
