DETAILED DESCRIPTION

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] A home computer embroidery machine includes an assembled frame 1 and a shuttle box mechanism 2, an embroidery drive member 3, a linkage mechanism 4, a thread rack mechanism 5 and an embroidery frame mechanism 6 installed on the assembled frame 1. A rotary hook 2-13 and a rotary hook drive assembly are provided in the shuttle box mechanism 2. The rotary hook drive assembly is connected to the rotary hook 2-13 and is used to drive the rotary hook 2-13 to rotate. A thread rack drive shaft 3-1 is provided in the embroidery drive member 3. The thread rack drive shaft 3-1 is used to drive the embroidery machine head to move up and down. The linkage mechanism 4 is connected to the rotary hook drive assembly and the thread rack drive shaft 3-1 respectively. The rotary hook 2-13 and the embroidery drive member 3 are driven to work through the linkage mechanism 4, reducing the number of drive members used to drive the rotary hook 2-13 and the embroidery drive member 3, thereby simplifying the overall structure of the home computer embroidery machine and reducing the production cost of the embroidery machine. The embroidery frame mechanism 6 is slidably installed on the assembled frame 1, and the cloth to be embroidered is moved by moving the embroidery frame mechanism 6.

[0048] The assembled frame 1 includes a frame base 1-1, a top seat plate 1-2 and two connecting wall panels 1-3. The top seat plate 1-2 is arranged above the frame base 1-1. The two connecting wall panels 1-3 are detachably connected to the frame base 1-1 and the two sides of the top seat plate 1-2 by bolts. By dividing the embroidery machine frame structure into the frame base 1-1, the top seat plate 1-2 and the connecting wall panels 1-3, it is convenient to manufacture each component of the embroidery machine frame structure. At the same time, this split structure can greatly improve the transportation convenience of the embroidery machine frame. In the subsequent maintenance process of the embroidery machine, different components of the frame structure can be replaced, reducing maintenance costs and improving maintenance efficiency.

[0049] The rack base 1-1 includes a base mounting plate 1-1-1 and a base plate 1-1-2. The base mounting plate 1-1-1 is connected to both sides of the base plate 1-1-2. The rack base 1-1 is assembled on the connecting wall plate 1-3 through the base mounting plate 1-1-1. A flat front surface is processed on the outer end surface of the base mounting plate 1-1-1 to ensure the assembly accuracy of the base mounting plate 1-1-1 and the connecting wall plate 1-3. A first reinforcing rib 1-1-3 is connected between the base mounting plate 1-1-1 and the base plate 1-1-2. The arrangement of the first reinforcing rib 1-1-3 facilitates increasing the connection strength of the base mounting plate 1-1-1 and the base plate 1-1-2.

[0050] A second reinforcing rib 1-1-4 is provided in the base plate 1-1-2 to increase the surface strength of the base plate 1-1-2, thereby ensuring the strength of the base plate 1-1-2 while achieving lightweighting of the base plate 1-1-2.

[0051] In this embodiment, both side end surfaces of the top seat plate 1-2 are surface-processed, and the both side end surfaces of the top seat plate 1-2 are assembled with the connecting wall panels 1-3.

[0052] A third reinforcing rib 1-2-1 is provided in the top seat plate 1-2. Similarly, the third reinforcing rib 1-2-1 is used to increase the surface strength of the top seat plate 1-2, thereby ensuring the strength of the base plate 1-1-2 while achieving lightweighting of the top seat plate 1-2.

[0053] A top boss 1-3-6 and a bottom boss 1-3-4 are provided on the inner end face of the connecting wall panel 1-3. A top mounting surface 1-3-1 is formed on the top boss 1-3-6, and a bottom mounting surface 1-3-2 is formed on the bottom boss 1-3-4. The top seat plate 1-2 is detachably connected to the connecting wall panel 1-3 through the top mounting surface 1-3-1, and the frame base 1-1 is detachably connected to the connecting wall panel 1-3 through the bottom mounting surface 1-3-2. By setting the top boss 1-3-6 and the bottom boss 1-3-4, the processing area of ​​the mounting surface on the connecting wall panel 1-3 can be reduced, thereby improving the processing efficiency of the connecting wall panel 1-3.

[0054] A wall panel groove 1-3-3 is provided in the bottom boss 1-3-4, and the bottom mounting surface 1-3-2 is arranged in the wall panel groove 1-3-3, thereby forming an annular protrusion on the outside of the bottom mounting surface 1-3-2. The annular protrusion provides positioning for the installation of the base mounting plate 1-1-1, thereby improving the assembly convenience of connecting the wall panel 1-3 and the rack base 1-1.

[0055] In order to further improve the assembly accuracy of the connecting wall panel 1-3 and the rack base 1-1, mounting surface grooves 1-3-5 are provided in the bottom mounting surface 1-3-2. The mounting surface grooves 1-3-5 are evenly distributed in the bottom mounting surface 1-3-2, so that the bottom mounting surface 1-3-2 has a grid structure. The area of ​​the bottom mounting surface 1-3-2 is reduced by the mounting surface grooves 1-3-5. On the one hand, the processing efficiency of the bottom mounting surface 1-3-2 can be improved. On the other hand, by reducing the area of ​​the bottom mounting surface 1-3-2, the contact area between the bottom mounting surface 1-3-2 and the end face of the base mounting plate 1-1-1 can be reduced, thereby preventing the processing error at a certain position on the bottom mounting surface 1-3-2 from affecting the assembly accuracy of the connecting wall panel 1-3 and the rack base 1-1.

[0056] The shape of the top mounting surface 1-3-1 is consistent with the shape of the end surfaces on both sides of the top seat plate 1-2, which facilitates ensuring the assembly accuracy between the connecting wall panel 1-3 and the top seat plate 1-2.

[0057] A supporting foot 1-4 is installed at the lower end of the connecting wall panel 1-3. The supporting foot 1-4 is used to support the embroidery machine as a whole. In some embodiments, a connecting screw is provided on the supporting foot 1-4. The height of the supporting foot 1-4 is adjusted by rotating the supporting foot 1-4, thereby leveling the embroidery machine.

[0058] The shuttle box mechanism 2 is fixedly mounted on the base plate 1-1-2. The rotary hook drive assembly installed in the shuttle box mechanism 2 includes a drive rod 2-14 and a transmission rod 2-16. The drive rod 2-14 and the transmission rod 2-16 are connected by helical gears. The power is transmitted to the rotary hook 2-13 through the transmission rod 2-16, thereby driving the rotary hook 2-13 to rotate. The transmission rod 2-16 is connected to the rotary hook, and the linkage mechanism 4 is connected to the drive rod 2-14.

[0059] The shuttle box mechanism includes a shuttle box body 2-1, a thread trimming motor 2-2, a thread trimming connecting rod 2-11 and a movable knife 2-12. A swing rod 2-7 is installed on the thread trimming motor 2-2. The swing rod 2-7 is connected to the movable knife 2-12 through the thread trimming connecting rod 2-11. The thread trimming motor 2-2 drives the swing rod 2-7 to swing, and transmits the swing amount to the movable knife 2-12 through the thread trimming connecting rod 2-11, thereby realizing the thread trimming operation of the movable knife 2-12, wherein the thread trimming connecting rod 2-11 and the movable knife 2-12 are both installed in the shuttle box body 2-1.

[0060] The shuttle box body 2-1 includes a transmission box body 2-1-1 and a driven box body 2-1-4. The driven box body 2-1-4 is connected to the transmission box body 2-1-1. The transmission box body 2-1-1 is used to install the drive rod 2-14, and the driven box body 2-1-4 is used to install the transmission rod 2-16. Box body grooves 2-15 are provided on the transmission box body 2-1-1 and the driven box body 2-1-4. The thread trimming connecting rod 2-11 is arranged in the box body groove 2-15. In order to facilitate reducing the overall volume of the embroidery machine shuttle box body mechanism, a motor installation space 2-3 is provided on one side of the transmission box body 2-1-1, and the thread trimming motor 2-2 is installed in the motor installation space 2-3.

[0061] By fixing the thread trimming motor 2-2 in the motor installation space 2-3 located on one side of the transmission box 2-1-1, the thread trimming motor 2-2 is integrated into the shuttle box 2-1, thereby making the structure of the shuttle box mechanism of the embroidery machine more compact, thereby reducing the overall size of the embroidery machine.

[0062] A recessed structure 2-1-5 is provided on the side wall of the transmission housing 2-1-1, and the motor installation space 2-3 is arranged in the recessed structure 2-1-5. Through the setting of the recessed structure 2-1-5, it is convenient to retract the thread trimming motor 2-2 into the transmission housing 2-1-1, thereby further reducing the overall size of the shuttle housing 2-1.

[0063] Two parallel motor mounting ribs 2-4 are connected to the side wall of the recessed structure 2-1-5, and a motor mounting space 2-3 is formed between adjacent motor mounting ribs 2-4, which facilitates the installation of the thread trimming motor 2-2 in the recessed structure 2-1-5.

[0064] A motor flange plate 2-6 is installed on the thread trimming motor 2-2, and the thread trimming motor 2-2 is installed on the motor flange plate 2-6 by bolts. The motor flange plate 2-6 is fixed to the upper end surface of the motor mounting rib 2-4 by bolts, so that the thread trimming motor 2-2 is installed in the motor mounting space 2-3 through the motor flange plate 2-6.

[0065] The upper end surface of the motor mounting rib 2-4 is set lower than the upper end surface of the shuttle box body 2-1, thereby preventing interference between the motor flange plate 2-6, the swing rod 2-7 and the box cover of the shuttle box body 2-1, and facilitating the installation of the thread trimming motor 2-2 through the upper end surface of the motor mounting rib 2-4.

[0066] An adjustment slot 2-5 is provided on the side wall of the motor mounting rib 2-4, and the adjustment slot 2-5 is connected to the motor mounting space 2-3, so that the thread trimming motor 2-2 in the motor mounting space 2-3 can be adjusted through the adjustment slot 2-5.

[0067] A mounting base plate 2-1-2 is provided on the lower end surface of the transmission case 2-1-1, and a limiting groove 2-1-3 is provided on the mounting base plate 2-1-2. The bottom end of the thread trimming motor 2-2 is assembled in the limiting groove 2-1-3. The position of the lower end of the thread trimming motor 2-2 is adjusted through the limiting groove 2-1-3, so as to improve the assembly convenience of the thread trimming motor 2-2.

[0068] An adjustment through slot is also provided in the limiting slot 2-1-3. The adjustment through slot in the limiting slot 2-1-3 is similar in structure to the adjustment through slot 2-5 on the motor mounting rib 2-4, both of which are waist-shaped holes.

[0069] A limit head 2-8 is installed on the motor flange plate 2-6, and the swing angle of the swing rod 2-7 is limited by the limit head 2-8.

[0070] A mounting block 2-10 is mounted on the lower end face of the driven box 2-1-4, and a cap frame guide shaft 2-9 is provided on the mounting block 2-10. The mounting block 2-10 extends toward the bottom of the driven box 2-1-4, thereby forming a guide space between the cap frame guide shaft 2-9 and the lower end face of the shuttle box body 2-1, which facilitates the stable installation of the cap frame on the shuttle box body 2-1.

[0071] The embroidery drive component 3 includes a thread rack drive shaft 3-1 and an embroidery motor 3-2. The embroidery motor 3-2 is installed on the connecting wall panel 1-3. The embroidery motor 3-2 is connected to the thread rack linkage belt 4-1 through a synchronous belt, thereby transmitting the power of the embroidery motor 3-2 to the thread rack drive shaft 3-1. The thread rack drive shaft 3-1 is connected to the kit shaft 7-1 of the embroidery machine head. The thread rack drive shaft 3-1 drives the cam to rotate, thereby driving the embroidery machine head to move up and down.

[0072] The linkage mechanism 4 includes a thread rack linkage belt 4-1, a linkage shaft 4-2 and a shuttle box linkage belt 4-3. The linkage shaft 4-2 is rotatably installed on the base plate 1-1-2 through a bearing seat.

The adjacent longitudinal frame adjustment members 6-4 are connected in the middle by a longitudinal adjustment shaft 6-6. The longitudinal frame adjustment members 6-4 on both sides are controlled by the longitudinal adjustment shaft 6-6 to work simultaneously, thereby ensuring that the adjustment seat 6-5 is in a translation state and preventing the adjustment seat 6-5 from tilting during movement. The transverse frame adjustment member 6-3 is installed in the adjustment seat 6-5, and the frame assembly 6-1 is connected to the transverse frame adjustment member 6-3 for moving the frame assembly 6-1 laterally.

[0077] In this embodiment, the longitudinal frame adjustment member 6-4 and the transverse frame adjustment member 6-3 are both synchronous belts, and the adjustment seat 6-5 is connected to the longitudinal frame adjustment member 6-4 through a splint structure. The synchronous belt is driven by a motor, thereby driving the adjustment seat 6-5 fixed on the synchronous belt to perform longitudinal translation. Similarly, the transverse frame adjustment member 6-3 is driven by a motor to work, thereby driving the frame assembly 6-1 fixed on the transverse frame adjustment member 6-3 to perform transverse translation.

[0078] In order to ensure the translational stability of the frame assembly 6-1, a guide rail 6-7 is provided on the connecting wall panel 1-3, and the splint structure is slidably installed on the connecting wall panel 1-3 through the guide rail 6-7. A limit sensor is provided on the guide rail 6-7, and the movement stroke of the splint structure is controlled by the limit sensor, thereby controlling the movement stroke of the frame assembly 6-1.

[0079] The frame assembly 6-1 includes a connecting plate 6-8 and an embroidery fixed frame 6-9. The connecting plate 6-8 is slidably installed in the adjustment seat 6-5 through a guide rail. One side of the connecting plate 6-8 is fixedly connected to the transverse frame adjustment member 6-3, and the other side of the connecting plate 6-8 is fixedly connected to the embroidery fixed frame 6-9, thereby driving the embroidery fixed frame 6-9 to move horizontally through the transverse frame adjustment member 6-3. The wire rack mechanism 5 includes a wire rack 5-1 and a wire feeding rack 5-2. The wire rack 5-1 is arranged on the wire feeding rack 5- 2.

[0085] The installation gap 8-2 is arranged on the mid-vertical plane of the needle bar driver 8, and the needle bar linkage rod assembly 9 is connected to the middle of the installation gap 8-2, ensuring that the force applied by the needle bar linkage rod assembly 9 to the needle bar driver 8 acts on the center position of the needle bar slide 8-4, thereby ensuring that the force applied to the needle bar driver 8 is located in the middle of the needle bar driver 8, reducing the wear of the needle bar driver 8 during use.

[0086] The needle bar joint 8-3 is provided with an upper end clamp 8-6 and a lower end clamp 8-7. By rotating the needle bar joint 8-3, the connecting head 12-1-3 of the embroidery needle bar 12-1 is clamped between the upper end clamp 8-6 and the lower end clamp 8-7, thereby driving the embroidery needle bar 12-1 to move up and down through the needle bar driver 8.

[0087] The needle bar linkage assembly 9 includes a swinging member and a tie rod 9-1. The swinging member is connected to the needle bar driver 8 via the tie rod 9-1. The tie rod 9-1 is arranged in the direction of movement of the needle bar driver 8. During the operation of the needle bar linkage assembly 9, the tie rod 9-1 can produce a certain swing perpendicular to the direction of movement of the needle bar driver 8. The arrangement of the tie rod 9-1 facilitates the stability of the needle bar linkage assembly 9 in driving the needle bar driver 8 to move. The swinging member includes a swing rod 9-2 and an eccentric shaft 9-3. One end of the swing rod 9-2 is rotatably mounted on the housing of the embroidery machine head, and the other end is rotatably connected to the tie rod 9-1. The eccentric shaft 9-3 is sleeved on the outside of the needle bar eccentric wheel 7-6, and the other end of the eccentric shaft 9-3 is rotatably connected to the middle part of the swing rod 9-2. The swing rod 9-2 is driven to swing through the needle bar eccentric wheel 7-6, thereby driving the needle bar driver 8 to move up and down.

[0088] The needle bar reset rod group 10 includes a first V-shaped rod, a second V-shaped rod and a reset connecting rod. The middle parts of the first V-shaped rod and the second V-shaped rod are rotatably connected to the embroidery machine head through a rotating shaft. The first V-shaped rod is connected to the needle bar reset cam 7-7, and the second V-shaped rod is connected to the first V-shaped rod through the reset connecting rod, and the end of the second V-shaped rod is arranged below the lower end clamp 8-7. When the embroidery needle bar 12-1 is embroidered downward, the needle bar reset cam 7-7 drives the first V-shaped rod to swing, which drives the second V-shaped rod to swing, thereby lifting and resetting the embroidery needle bar 12-1 through the second V-shaped rod.

[0089] The thread take-up lever driving rod group 11 includes a thread take-up shaft 11-3 and a first thread take-up link 11-1 and a second thread take-up link 11-2 fixedly connected to the thread take-up shaft 11-3. The first thread take-up link 11-1 is connected to the thread take-up lever cam 7-5, and the second thread take-up link 11-2 is in contact with the thread take-up lever 12-2. The thread take-up shaft 11-3 is connected to the embroidery machine head housing. The thread take-up lever cam 7-5 rotates, driving the first thread take-up link 11-1 to swing, thereby driving the thread take-up shaft 11-3 to rotate, and the second thread take-up link 11-2 swings as the thread take-up shaft 11-3 rotates, thereby driving the thread take-up lever 12-2 to move up and down.

[0090] The cam kit 7, the needle bar driver 8, and the needle bar linkage rod assembly 9 are connected to form a needle bar driving mechanism for driving the needle bar body 12-1-1 to move downward to embroider the cloth.

[0091] The embroidery needle bar 12-1 includes a needle bar body 12-1-1, a presser foot 12-1-2 and a connector 12-1-3. The connector 12-1-3 is fixedly mounted on the needle bar body 12-1-1.
