Description

Technical Field

[0001] This utility model relates to the technical field of computer embroidery machine equipment, specifically to an embroidery frame drive device for a computer embroidery machine. Background Technology

[0002] Computerized embroidery machines, also known as embroidery machines or computerized embroidery rigs, are the most advanced embroidery machinery of our time. They combine computer-aided design and electromechanical control technology to achieve the high speed and efficiency of traditional hand embroidery, and can meet the requirements of "multi-layered, multi-functional, uniform, and perfect" work that cannot be achieved by hand. Stepper motors drive the embroidery frame to precisely move the fabric along the designed path, while the main shaft motor controls the up-and-down movement of the needle, which works in conjunction with the rotary hook to form lockstitch stitches.

[0003] Utility model patent CN208136488U discloses a drive device for an embroidery frame of a cylindrical computerized embroidery machine. The device includes a drive main rod with two integrally formed protrusions at its left and right ends. A connecting body is fixedly connected to the right end of each protrusion. At least four lifting ports are opened at the upper end of the drive main rod, and at least four vertical columns are movably connected to the upper end of the drive main rod through these lifting ports. Connecting rods are connected to the upper ends of the vertical columns, and four small holes are opened at the four corners of the upper end of each connecting rod. This drive device facilitates the movement of the drive main rod during embroidery by using the protrusions, which are coated with a 0.2cm-0.5cm thick anti-rust coating. The protrusions also provide rust prevention. The connecting body prevents the drive main rod from falling off during movement. Screw holes, evenly distributed horizontally on the upper front end of the drive main rod, facilitate the fixing of the drive main rod when the embroidery machine is not in operation.

[0004] However, the embroidery frame drive device of this computer embroidery machine is prone to damaging the fabric when installing it onto the embroidery frame, leaving indentations on the fabric surface. When pressing the fabric, it is necessary to pull the fabric taut before installing it. Therefore, a computer embroidery frame drive device is proposed to solve the problems mentioned above.

[0024] 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.

[0025] Please see Figures 1 to 4The embroidery frame driving device of the computer embroidery machine in this embodiment includes a mounting base 1, a longitudinal base 2 slidably mounted on the top of the mounting base 1, a transverse base plate 3 slidably mounted on the top of the longitudinal base 2, and two sets of mounting upright plates 4 fixedly mounted on the top of the transverse base plate 3. Each set of mounting upright plates 4 consists of two plates, and a variable diameter clamping assembly is provided between the two mounting upright plates 4 in each set.

[0026] The variable diameter clamping assembly includes two rotating shafts 5 rotatably mounted between two mounting plates 4. Variable diameter pressure rollers 6 are fixedly mounted on the surface of the rotating shafts 5, and the distance between the two variable diameter pressure rollers 6 is equal to the maximum diameter of the variable diameter pressure rollers 6.

[0027] Specifically, the fabric is passed between the two sets of variable diameter pressure rollers 6 on both sides. The rotating shaft 5 rotates, which drives the variable diameter pressure rollers 6 to rotate, so that the gap between the variable diameter pressure rollers 6 is reduced, pressing the fabric between the two variable diameter pressure rollers 6. At the same time, the fabric is pulled outward, so that the fabric is tightened, making it easier to embroider.

[0028] Please see Figure 2 In this embodiment, a transmission box 7 is fixedly installed on one side of the mounting plate 4, and two connecting shafts 8 are rotatably installed on the inner side wall of the transmission box 7. One end of the connecting shaft 8 is fixedly connected to one end of the rotating shaft 5.

[0029] A transmission gear 9 is fixedly mounted on the surface of the connecting shaft 8, and the two transmission gears 9 mesh with each other. When one transmission gear 9 rotates, it drives the other transmission gear 9 to rotate, causing the two rotating shafts 5 to rotate in opposite directions.

[0030] Please see Figure 3 and Figure 4 In this embodiment, a turntable 10 is rotatably mounted on one side of the transmission box 7. The turntable 10 is fixedly connected to one end of the connecting shaft 8, and a drive rod 11 is fixedly mounted on one side of the turntable 10.

[0031] A mounting rod 12 is fixedly mounted on one side of the mounting plate 4. A fixed connecting plate 13 is rotatably mounted on the surface of the mounting rod 12. A rotating connecting plate 14 is rotatably mounted on the surface of the drive rod 11. A drive cylinder 15 is fixedly mounted between the fixed connecting plate 13 and the rotating connecting plate 14. The drive cylinder 15 drives the drive rod 11 to rotate, which in turn drives the turntable 10 to rotate, and in turn drives one of the transmission gears 9 to rotate.

[0032] Please see Figure 1 and Figure 2 In this embodiment, the top of the mounting base 1 is provided with three longitudinal sliding grooves 16, and a longitudinal sliding slider 17 is slidably installed inside the longitudinal sliding groove 16. The top of the longitudinal sliding slider 17 is fixedly connected to the bottom of the longitudinal sliding base 2.

[0033] One of the longitudinal movement slots 16 has a longitudinal movement screw 18 rotatably mounted inside, threadedly connected to a longitudinal movement slider 17. A longitudinal movement motor 19 is fixedly mounted on one side of the mounting base 1, and the output shaft of the longitudinal movement motor 19 is fixedly connected to one end of the longitudinal movement screw 18. The top of the longitudinal movement base 2 has three transverse movement slots 20. A transverse movement slider 21 is slidably mounted inside the longitudinal movement slider 17 and fixedly connected to the bottom of the transverse movement base plate 3. The longitudinal movement motor 19 drives the longitudinal movement screw 18 to rotate, which in turn moves the longitudinal movement slider 17, causing the longitudinal movement base 2 to move longitudinally, and thus the fabric to move longitudinally.

[0034] Finally, a transverse screw 22, threadedly connected to a transverse slider 21, is rotatably mounted inside one of the transverse grooves 20. A transverse motor 23 is fixedly mounted on one side of the longitudinal base 2, and the output shaft of the transverse motor 23 is fixedly connected to one end of the transverse screw 22. The transverse motor 23 drives the transverse screw 22 to rotate, which in turn drives the transverse slider 21 to move, which in turn drives the transverse base plate 3 to move, thus causing the fabric to move laterally.

[0035] The working principle of the above embodiment is as follows: the fabric is passed between the two sets of variable diameter pressure rollers 6 on both sides, the rotating shaft 5 rotates, which drives the variable diameter pressure rollers 6 to rotate, so that the gap between the variable diameter pressure rollers 6 becomes smaller, pressing the fabric between the two variable diameter pressure rollers 6, and at the same time pulling the fabric outward, so that the fabric is taut.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions.
