DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] The utility model embodiment of a single-head embroidery machine frame includes a mounting base 1, a one-piece shuttle box body 4 fixedly mounted on the mounting base 1, a support arm 2 fixedly mounted on the one-piece shuttle box body 4, and a machine head 3 detachably connected to the support arm 2, the machine head 3 is used to install a needle bar frame, and the one-piece shuttle box body 4 is used to guide the weaving thread to gather; the horizontal cross-sectional range of the mounting base 1 is larger than the horizontal cross-sectional range of the one-piece shuttle box body 4, the support arm 2 and the machine head 3. Figure 1 .

[0032] In the present application, the frame includes a mounting base 1, a one-piece shuttle box 4, a support arm 2 and a machine head 3. The mounting base 1 is arranged on a workbench, and the one-piece shuttle box 4 is fixedly mounted on the mounting base 1. The one end of the support arm 2 close to the ground is connected to the one-piece shuttle box 4, and the one end away from the ground is connected to the machine head 3, so that the machine head 3 is located above the mounting base 1. The machine head 3 is used to install a needle bar frame, on which a needle is installed. The one-piece shuttle box 4 is used to guide the threads to gather. When the cloth is fixed on the workbench, the one-piece shuttle box 4 guides the threads to gather. At the same time, the needle bar frame located above the mounting base 1 moves up and down, driving the needle to move up and down, so that the needle embroiders the gathered threads on the cloth, thereby forming an embroidery.

[0033] Since the one-piece shuttle box 4, the supporting arm 2 and the machine head 3 are all located above the mounting base 1, in the present application, the cross-sectional range of the mounting base 1 in the horizontal direction is made larger than the cross-sectional range of the one-piece shuttle box 4, the supporting arm 2 and the machine head 3 in the horizontal direction, thereby increasing the contact area between the machine frame and the workbench, lowering the center of gravity of the machine frame, and thus improving the stability of the machine frame structure, reducing the jitter and noise generated when the embroidery machine runs at high speed, thereby ensuring the quality of the embroidery products and providing a good production environment.

[0034] Furthermore, in the present application, the end of the support arm 2 close to the ground is fixedly connected to the one-piece shuttle box 4, and the end away from the ground is detachably connected to the machine head 3. The cross-sectional range of the support arm 2 in the horizontal direction gradually decreases from the end close to the ground to the end away from the ground, thereby further lowering the center of gravity of the machine frame, improving the stability of the machine frame structure, and reducing the vibration and noise generated when the embroidery machine runs at high speed, which not only ensures the quality of the embroidery, but also provides a good production environment. In actual implementation, the mounting base 1 of the machine frame, the one-piece shuttle box 4, the support arm 2 and the machine head 3 can be formed by high-strength aluminum alloy die-casting, thereby enhancing the structural strength of the machine frame and making the overall weight of the machine frame lighter and easier to carry.

[0035] In the present application, the reason why the machine head 3 and the end of the supporting arm 2 away from the ground are detachably connected is to enable the machine head 3 and the supporting arm 2 to be designed and processed separately, so as to meet the different processing requirements of the machine head 3 and the supporting arm 2, thereby ensuring the processing accuracy of the machine head 3 and the supporting arm 2, and reducing the overall processing difficulty of the frame, thereby enhancing the practicality of the embroidery machine frame.

[0036] In this embodiment, the mounting base 1 is a U-shaped structure, and the extension direction of the machine head 3 on the supporting boom 2 is consistent with the extension direction of the opening of the U-shaped structure. Figure 1In the present application, the mounting base 1 is configured as a U-shaped structure, and the cross-sectional range of the mounting base 1 in the horizontal direction is larger than the cross-sectional range of the one-piece shuttle box 4, the supporting arm 2 and the machine head 3 in the horizontal direction, thereby reducing the overall weight of the frame and ensuring the stability of the mounting base 1 supporting the one-piece shuttle box 4, the supporting arm 2 and the machine head 3, thereby improving the stability of the frame structure.

[0037] When the machine head 3 is fixedly mounted on the end of the supporting arm 2 away from the ground, the extension direction of the machine head 3 on the supporting arm 2 is consistent with the extension direction of the opening of the U-shaped mounting base 1, so that the center of gravity of the overall structure of the frame is located in the center of the mounting base 1, so that the mounting base 1 is subjected to force more evenly, thereby providing strong support for the integrated shuttle box body 4, the supporting arm 2 and the machine head 3, and further improving the stability of the frame structure.

[0038] In this embodiment, the one-piece shuttle box body 4 includes a shuttle box body mounting seat 41 and a shuttle box 42. The shuttle box body mounting seat 41 is fixedly connected to the mounting base 1 to fix the shuttle box 42 on the mounting base 1. The shuttle box 42 is used to guide the weaving thread to gather. The end of the supporting arm 2 close to the ground is fixedly connected to the shuttle box body mounting seat 41. Figure 1 and Figure 3 In the present application, the one-piece shuttle box body 4 includes a shuttle box body mounting seat 41 and a shuttle box 42, and the shuttle box 42 is fixedly mounted on the mounting base 1 through the shuttle box body mounting seat 41 being fixedly connected to the mounting base 1. The end of the support arm 2 close to the ground is fixedly connected to the shuttle box body mounting seat 41, so that the shuttle box 42 is located between the support arm 2 and the mounting base 1. When the embroidery machine is running, the shuttle box 42 guides the threads to gather, and at the same time, the needle bar frame located above the shuttle box 42 moves up and down, so that the needles on the needle bar frame embroider the gathered threads on the fabric on the workbench, thereby forming embroidery.

[0039] In the present application, the shuttle box 42 and the shuttle box body mounting seat 41 are set as an integrated structure. Therefore, the shuttle box 42 can be fixedly mounted on the mounting base 1 through the fixed connection between the shuttle box body mounting seat 41 and the mounting base 1, and the structural strength and stability of the machine frame are made greater, thereby reducing the jitter and noise generated when the embroidery machine runs at high speed, which not only ensures the quality of the embroidery, but also provides a good production environment.

[0040] In this embodiment, a support column 11 is provided at one end of the mounting base 1 away from the ground, and a sleeve 411 is provided on the shuttle box mounting seat 41 to be sleeved on the support column 11. Figure 1 , Figure 2 and Figure 3In the present application, a support column 11 is provided at one end of the mounting base 1 away from the ground, and a sleeve 411 is provided on the shuttle box mounting seat 41. When the shuttle box mounting seat 41 is fixedly connected to the mounting base 1, the sleeve 411 on the shuttle box mounting seat 41 is sleeved on the support column 11 on the mounting base 1, so that the stability of the connection between the shuttle box mounting seat 41 and the mounting base 1 is enhanced through the cooperation between the support column 11 and the sleeve 411, thereby enhancing the structural strength and stability of the frame.

[0041] In actual implementation, multiple sleeves 411 can be provided on the shuttle box mounting seat 41, and multiple support columns 11 are provided at one end of the mounting base 1 away from the ground. When the shuttle box mounting seat 41 and the mounting base 1 are fixedly connected, the multiple sleeves 411 on the shuttle box mounting seat 41 are respectively sleeved with the multiple support columns 11 at corresponding positions on the mounting base 1, so that the stability of the connection between the shuttle box mounting seat 41 and the mounting base 1 is further enhanced through the cooperation between the multiple support columns 11 and the multiple sleeves 411. It can be foreseen that: a threaded hole is provided on the top of the support column 11, and when the sleeve 411 on the shuttle box mounting seat 41 is sleeved on the support column 11 of the mounting base 1, it is screwed with the threaded hole on the top of the support column 11 through a bolt until the nut of the bolt abuts against the upper surface of the sleeve 411, thereby fixing the shuttle box mounting seat 41 on the mounting base 1.

[0042] In this embodiment, the support boom 2 includes a vertically arranged support beam 21, and a connecting beam 22 extending horizontally on the support beam 21. The end of the support beam 21 close to the ground is fixedly connected to the shuttle box mounting seat 41, and the connecting beam 22 extends horizontally at the end of the support beam 21 away from the ground. The machine head 3 is fixedly connected to the end of the connecting beam 22 away from the support beam 21. Figure 1 and Figure 4 In the present application, the support arm 2 includes a support beam 21 and a connecting beam 22. The support beam 21 is vertically arranged, and one end of the support beam 21 close to the ground is fixedly connected to the shuttle box mounting seat 41. The connecting beam 22 extends horizontally at the end of the support beam 21 away from the ground, so that the machine head 3 is connected to the end of the connecting beam 22 away from the support beam 21, and the machine head 3 is fixedly installed above the shuttle box 42. Then, the needle bar frame on the machine head 3 moves up and down, so that the needles on the needle bar frame embroider the threads collected in the shuttle box 42 on the fabric on the workbench, thereby forming embroidery.

[0043] In the present application, the support beam 21 and the connecting beam 22 also adopt an integrated structure, thereby enhancing the integrity of the support boom 2 structure, thereby making the structural strength and stability of the frame greater. In the present embodiment, the specific implementation method of the end of the support beam 21 close to the ground being fixedly connected to the shuttle box body mounting seat 41 can be adopted: the shuttle box body mounting seat 41 is provided with a through hole, and the end of the support beam 21 close to the ground is provided with a threaded hole. After the bolt passes through the through hole from the bottom of the shuttle box body mounting seat 41, it is screwed with the threaded hole on the support beam 21 until the nut of the bolt abuts against the lower surface of the shuttle box body mounting seat 41, thereby achieving the fixed connection between the support beam 21 and the shuttle box body mounting seat 41.

[0044] In this embodiment, the cross-sectional range of the support beam 21 in the horizontal direction gradually decreases from the end close to the ground to the end far from the ground. Figure 4 . In the present application, since the support beam 21 extends upward on the shuttle box mounting seat 41, and the connecting beam 22 extends horizontally at the end of the support beam 21 away from the ground, the center of gravity height of the support beam 21 has a greater impact on the stability of the machine frame structure. In this embodiment, the cross-sectional range of the support beam 21 in the horizontal direction is gradually reduced from the end close to the ground to the end away from the ground, thereby reducing the center of gravity height of the support beam 21, further improving the stability of the machine frame structure, reducing the jitter and noise generated when the embroidery machine runs at high speed, and ensuring the quality of the embroidery products while providing a good production environment.

[0045] In this embodiment, the support boom 2 further includes a reinforcing rib 23, which extends from the support beam 21 to the connecting beam 22. Figure 4 In the present application, the support arm 2 also includes a reinforcing rib 23, and a portion of the reinforcing rib 23 extends vertically along the support beam 21, and another portion extends horizontally along the connecting beam 22, so that the support arm 2 has a stronger integrity and a greater structural strength, thereby making the structural strength and stability of the machine frame greater, further reducing the jitter and noise generated when the embroidery machine runs at high speed, which not only ensures the quality of the embroidery products, but also provides a good production environment.

[0046] In this embodiment, the embroidery machine frame also includes a driving device, which is arranged on the supporting arm 2 and the machine head 3, and is used to drive the needle bar frame to move on the machine head 3. In this application, the embroidery work is performed by moving the needle bar frame on the machine head 3 up and down, so that the needles on the needle bar frame embroider the collected threads on the cloth on the workbench to form embroidery. Therefore, the embroidery machine frame also includes a driving device, which is arranged on the supporting arm 2 and the machine head 3. The driving device drives the needle bar frame to move on the machine head 3, drives the needles on the needle bar frame to move synchronously, and completes the embroidery work on the cloth.

[0047] In this embodiment, a mounting groove 211 is provided on the support beam 21, and the driving device includes a driving motor provided in the mounting groove 211, and the driving motor is used to provide power for the movement of the needle bar frame on the machine head 3. Figure 4 . In the present application, the driving device includes a driving motor, which provides power to the needle bar frame through the driving motor, so that the needle bar frame moves on the machine head 3, thereby driving the needle located on the needle bar frame to move synchronously, and completing the embroidery work of the cloth. Since the connecting beam 22 extends horizontally at the end of the support beam 21 away from the ground, the machine head 3 is fixedly connected to the end of the connecting beam 22 away from the support beam 21, and the driving motor is heavy, setting the driving motor on the connecting beam 22 or the machine head 3 will cause the center of gravity of the driving motor to deviate from the vertical center axis of the support beam 21, thereby affecting the stability of the machine frame structure. Therefore, in the present application, a mounting groove 211 is provided on the support beam 21, and the mounting groove 211 is as close to the bottom of the support beam 21 as possible, and the driving motor is fixedly installed in the mounting groove 211, so that the center of gravity of the driving motor is close to the vertical center axis of the support beam 21, and the height of the center of gravity of the driving motor is reduced, thereby enhancing the stability of the machine frame structure.

[0048] It can be foreseen that: in actual implementation, the driving device also includes a transmission belt and a transmission wheel. The transmission wheel is arranged on the machine head 3. One end of the transmission belt is sleeved on the rotating shaft of the driving motor, and the other end is sleeved on the transmission wheel. Therefore, through the transmission belt connection, the driving motor drives the transmission wheel to rotate synchronously, and then the transmission wheel drives the needle bar rack on the machine head 3 to move up and down, thereby driving the needle on the needle bar rack to move synchronously to complete the embroidery work of the cloth.

[0049] In this embodiment, gripper sleeve installation grooves 12 are provided on both sides of the mounting base 1, and the gripper sleeve installation grooves 12 are used to move the whole machine. In this application, gripper sleeve installation grooves 12 are provided on both sides of the mounting base 1, and the gripper sleeves can be installed through the gripper sleeve installation grooves 12, so that the user can move the whole embroidery machine through the gripper sleeves installed on both sides of the mounting base 1, thereby making the use of the embroidery machine frame more convenient and more practical.

[0050] In this embodiment, a support leg 13 is provided at one end of the mounting base 1 close to the ground, and a shock absorbing pad 131 is provided at the bottom of the support leg 13. Figure 2. In the present application, a support leg 13 is provided at one end of the mounting base 1 close to the ground, and the mounting base 1 is placed on the workbench by abutting the support leg 13 against the workbench. A shock-absorbing pad 131 is provided at the bottom of the support leg 13, and the shock-absorbing pad 131 can reduce the jitter and noise generated when the embroidery machine runs at high speed, thereby further ensuring the quality of the embroidery and providing a good production environment. It can be foreseen that: in actual implementation, the shock-absorbing pad 131 can be made of an elastic material, such as rubber, so that the shock-absorbing pad 131 abuts against the workbench, and the jitter generated when the embroidery machine runs at high speed can be buffered.
