Detailed implementation method:
[0027] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4:
[0028] An embroidery frame mounting structure for an embroidery machine includes a crossbeam 1, a transverse guide rail 2 on the crossbeam 1, a slider sliding on the transverse guide rail 2, a connecting plate 3 mounted on the slider, an assembly plate 4 mounted on the connecting plate 3, and a flat embroidery frame 5 mounted on the assembly plate 4. A guide plate 6 is vertically mounted on the crossbeam 1, and the length direction of the guide plate 6 is transversely arranged. The flat embroidery frame 5 is provided with multiple mounting seats 7, which are located on the left and right sides of the connecting plate 3 respectively. The mounting seats 7 are provided with multiple rolling elements that roll in contact with the guide plate 6, and the rolling elements are located on the front and rear sides of the guide plate 6 respectively.
[0029] like Figure 1-4As shown, the connecting plate 3 slides horizontally on the horizontal guide rail 2 via a slider, which drives the flat embroidery frame 5 connected to the connecting plate 3 via the mounting plate 4 to move. During the horizontal sliding of the flat embroidery frame 5, the two rolling parts set on the mounting base 7 are in rolling contact with the guide plate 6, which limits the flat embroidery frame 5 to the front and back and prevents it from shaking back and forth. The mounting base 7 is located on the left and right sides of the connecting plate 3, that is, it limits the flat embroidery frame 5 to the front and back at both ends of the left and right sides, effectively preventing the flat embroidery frame 5 from shaking, thereby avoiding the situation of the frame flying out, resulting in precise embroidery and good embroidery quality.
[0030] This utility model features a guide plate 6 on a crossbeam 1 and mounting seats 7 on the flat embroidery frame, connecting the left and right sides. Two rolling elements are mounted on the mounting seats 7, located on the front and rear sides of the guide plate 6 respectively. This effectively limits the front and rear movement of both ends of the flat embroidery frame 5, preventing the frame from shaking and thus avoiding frame slippage. This results in precise embroidery and high-quality embroidery. At the same time, the rolling elements and the guide plate 6 experience rolling friction, resulting in low friction and minimal wear.
[0031] The structure and installation structure of the rolling element: The guide plate 6 is located between the transverse guide rail 2 and the flat embroidery frame 5. The mounting seat 7 is located above the flat embroidery frame 5. The rolling element is a bearing 8 located below the mounting seat 7. The bearing 8 is mounted on the mounting seat 7 by connecting screws 9. The head of the connecting screw 9 is mounted on the inner ring of the bearing 8. The shank of the connecting screw 9 is fixedly connected to the mounting seat 7.
[0032] Structure of mounting base 7: The mounting base 7 includes a mounting plate 7a and a pad 7b. One end of the mounting plate 7a is fitted with the connecting screw 9, and the other end is mounted on the flat embroidery frame 5. The pad 7b is disposed between the mounting plate 7a and the flat embroidery frame 5. The mounting plate 7a and the pad 7b are separate structures, and the pad 7b can be replaced according to the height difference between the flat embroidery frame 5 and the guide plate 6, thus having high adaptability.
[0033] Connection structure between connecting screw 9 and mounting plate 7a: The shank of connecting screw 9 can be screwed onto mounting plate 7a, and the shank of connecting screw 9 can also extend out of mounting plate 7a and be screwed onto a nut, with a protective cap fitted over the nut. In this embodiment, the shank of connecting screw 9 near the flat embroidery frame 5 extends out of mounting plate 7a and is screwed onto the nut, while the shank of connecting screw 9 away from the flat embroidery frame 5 is screwed onto mounting plate 7a.
[0034] To facilitate adjustment of the front and rear positions of the mounting base 7, both the mounting plate 7a and the pad 7b are provided with oblong holes arranged longitudinally in the length direction. The shank of the screw passes through the oblong holes of the mounting plate 7a and the pad 7b in sequence and is screwed into the flat frame 5.
[0035] To improve the wear resistance of the rolling elements and prevent the bearing 8 from wearing out and failing to contact the guide plate 6, which would cause the flat frame 5 to wobble, such as... Figure 2 ,3 As shown, the outer ring of the bearing 8 is fitted with a plastic ring 10, which makes rolling contact with the guide plate 6.
[0036] To better prevent the flat embroidery frame 5 from shaking, such as Figure 1 , 2 As shown, the connecting plate 3 has two or more mounting seats 7 spaced apart on its left and right sides, and each mounting seat 7 is equipped with the rolling element. In this embodiment, the connecting plate 3 has three mounting seats 7 spaced apart on its left and right sides.
[0037] The driving structure of connecting plate 3: as follows Figure 1 As shown, the crossbeam 1 is L-shaped, including a vertical plate 1a and a horizontal plate 1b. A motor 11 is located at the rear of the vertical plate 1a, and a ring-shaped belt 12 driven by the motor 11 is located at the front of the vertical plate 1a. A pressure plate is located above the lower belt 12. Fastening screws pass through the pressure plate and the belt 12 and are screwed to the connecting plate 3. The transverse guide rail 2 and the guide plate 6 are set on the horizontal plate 1b. The structure is simple and easy to process and install.
[0038] To reduce assembly steps and ensure a secure and reliable connection, the guide plate 6 and the crossbeam 1 are integrally formed.
[0039] The structure of connecting plate 3 and its mounting structure: such as Figure 1 , 4 As shown, the connecting plate 3 is elongated and includes a front plate 3a, a rear plate 3b arranged in parallel, and an upper plate 3c connecting the front plate 3a and the rear plate 3b. The slider is located between the front plate 3a and the rear plate 3b and below the upper plate 3c. The lower end of the front plate 3a is provided with a lower plate 3d, and the mounting plate 4 is installed on the lower plate 3d.
[0040] To reduce assembly steps and ensure a secure and reliable connection, the connecting plate 3 is integrally formed by bending.
[0041] The mounting structure of the connecting plate 3 and the slider, and the mounting structure of the assembly plate 4 and the connecting plate 3 and the flat frame 5, the shank of the screw passes through the upper plate 3c and is screwed to the slider, the shank of the screw passes through the lower plate 3d and is screwed to the assembly plate 4, and the shank of the screw passes through the flat frame 5 and is screwed to the assembly plate 4.
[0042] To enhance the strength of the connecting plate 3, the connecting plate 3 also includes an intermediate plate 3e located below the upper plate 3c. The front end of the intermediate plate 3e is connected to the front plate 3a, and the rear end is connected to the rear plate 3b. The intermediate plate 3e is not provided at the slider.
[0043] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
