[0002] Socks are essential in people's lives. They not only provide wear and anti-slip protection, but also keep you warm and absorb sweat. They are primarily composed of a toe, sole, heel, barrel, and cuff. After knitting, the machine head and cap need to be raised to a certain height to allow space for the swing arm mechanism and coil grabbing mechanism to reach above the needle cylinder, grab all the coils on the needles, and transfer them to the needle disc for sewing. Once all the coils have been removed, the machine head lowers and resets to knit the next sock. However, existing machine heads and caps are raised and lowered separately by two lifting mechanisms, resulting in a large space occupation and thus increasing the overall structure.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 7 As shown, a vertical lifting component of a sock machine includes a lifting assembly, a head component, a half head assembly, and a cap cover. The half head assembly is installed on the head component. The lifting assembly drives and connects the head component and the cap cover. It also includes a switching mechanism. The switching mechanism controls the lifting assembly to only drive the head component to lift or drive the head component and the cap cover to lift together. During the lifting process of the head component, the half head assembly is driven to lift together.

[0026] like Figure 1 、 Figure 3 、 Figure 4 As shown, the lifting assembly includes a base 1 and a motor base 23. A guide sleeve 20 is installed on the upper part of the base 1. A screw rod 22 is rotatably arranged in the guide sleeve 20. A screw nut 21 is arranged on the screw rod 22. The screw nut 21 is fixedly installed on the guide sleeve 20. A lifting motor 24 is installed on the motor base 23. The lifting motor 24 drives the connecting screw rod 22. The head component includes a head cover 30. The head cover 30 is connected to the motor base 23. A lifting shaft sleeve 2 is provided on the upper part of the base 1. A guide disc lifting sleeve 3 is provided on the lifting shaft sleeve 2. The lifting shaft sleeve 2 and the guide disc lifting sleeve 3 are coaxially arranged, and the guide disc lifting sleeve 3 can move along the lifting shaft sleeve 2. The side of the yarn guide disc lifting sleeve 3 is connected to a connecting block 19, the hat cover includes a yarn guide disc 27, and a connecting seat 28 is provided on the yarn guide disc 27, and the connecting seat 28 is connected to the connecting block 19. A cylinder rod 25 is connected to the bottom of the motor seat 23, and the screw rod 22 is rotatably arranged in the cylinder rod 25. A card slot 26 is provided on the side of the cylinder rod 25 close to the yarn guide disc lifting sleeve 3. The switching mechanism includes a mounting plate 5, and the yarn guide disc lifting sleeve 3 is installed on the side close to the cylinder rod 25. A mounting plate 5 is provided on the upper part of the mounting plate 5. The rotating groove 60 is arranged along the front and rear directions. A bayonet 6 is rotatably provided in the rotating groove 60. The bayonet 6 is provided with a bayonet 7 on the side of the cylinder rod 25. An opening 61 is provided on the side of the mounting plate 5 close to the cylinder rod 25. One end of the opening 61 is connected to the side of the mounting plate 5, and the other end is connected to the rotating groove 60. Part of the cylinder rod 25 is located in the opening 61, and the cylinder rod 25 can be lifted and lowered in the opening 61. An adjusting mechanism 8 for driving the bayonet 7 to rotate is provided on the mounting plate 5 . The adjusting mechanism 8 is located on the side of the bayonet 6 away from the hinge.

[0027] The lifting motor 24 drives the screw rod 22 to rotate. Because the screw nut 21 is fixed in position, the motor base 23 can be raised and lowered. During the raising and lowering of the motor base 23, the head components are synchronously raised and lowered via the head cover 30. By adjusting the position of the bayonet 6, the bayonet 6 is rotated toward the cylinder rod 25, causing the bayonet 7 on the bayonet 6 to engage the slot 26 on the cylinder rod 25. When the motor base 23 is raised or lowered, the cylinder rod 25 and the yarn guide disc lifting sleeve 3 cooperate to drive the cap cover up or down. When the bayonet 6 is located in the rotation slot 60, away from the cylinder rod 25, the motor base 23 does not contact the bayonet 6 during raising or lowering, and thus does not drive the yarn guide disc lifting sleeve 3 and, consequently, the cap cover.

[0028] like Figure 2 As shown, the adjustment mechanism 8 includes a mounting block 9 mounted on the mounting plate 5. A baffle 11 is installed on the side of the mounting block 9 close to the guide disc lifting sleeve 3. A notch 10 is provided in the middle of the mounting block 9. The end of the bayonet 6 away from the hinge point is located in the notch 10. A mounting slot 12 is provided on the mounting block 9. The mounting slot 12 is connected to the notch 10. A push block 15 is installed in the mounting slot 12. A spring 16 is installed in the push block 15. The end of the spring 16 away from the push block 15 is placed against the baffle 11. A through hole 13 is provided on the mounting block 9 at a position corresponding to the mounting slot 12. The through hole 13 is connected to the notch 10. A cylinder 57 is installed in the through hole 13. The cylinder 57 drives a piston 14. The push block 15 and the piston 14 are respectively located on both sides of the bayonet 6.

[0029] Under the action of spring 16, push block 15 tends to move toward bayonet 6, thereby abutting bayonet 6. Cylinder 57 controls the expansion and contraction of piston 14, which abuts bayonet 6 from the other side. To rotate bayonet 6 toward rod 25, cylinder 57 controls piston 14 to retract into through-hole 13. Push block 15 rotates against bayonet 6, forcing it toward rod 25 and allowing bayonet notch 7 on bayonet 6 to engage with slot 26 on rod 25.

[0030] Furthermore, a contact sensor 58 is mounted on the mounting block 9, with the end of the contact sensor 58 extending into the notch 10. When the latch 6 rotates toward the barrel 25, it contacts the contact sensor 58. The contact sensor 58 generates a corresponding signal, indicating that the machine head assembly and the cap cover are now in the state of being driven to rise and fall together.

[0031] A guide cylinder 17 is provided on the base 1, and a guide rod 18 is installed on the yarn guide disc lifting sleeve 3. A part of the guide rod 18 is located in the guide cylinder 17. The lifting and lowering of the yarn guide disc lifting sleeve 3 is guided by the cooperation of the guide cylinder 17 and the guide rod 18.

[0032] like Figure 7As shown, a head transmission seat 31 is provided on the upper part of the head cover 30, and a spline shaft 1 32 and a spline shaft 2 33 are rotatably provided in the head transmission seat 31. The spline shaft 1 32 and the spline shaft 2 33 are connected by a belt drive. A lifting shaft sleeve 2 4 is passed through the guide disc lifting sleeve 3. The lifting shaft sleeve 2 4 is located above the lifting shaft sleeve 1 2. The upper end of the lifting shaft sleeve 2 4 is connected to the bottom of the head transmission seat 31, and the spline shaft 2 33 passes through the lifting shaft sleeve 2 4, the guide disc lifting sleeve 3, and the lifting shaft sleeve 1 2. A driving motor 56 is provided at the bottom of the base 1, and the driving motor 56 is connected to the lower end of the spline shaft 2 33. A driven pulley 34 and a driving pulley 36 are rotatably mounted on the head transmission base 31. A synchronous belt 41 is connected between the driven pulley 34 and the driving pulley 36. Spline shaft 1 32 and spline shaft 2 33 are respectively passed through the driven pulley 34 and the driving pulley 36. A transmission sleeve 38 is mounted on the upper portion of the driving pulley 36. A pulley seat 39 is mounted on the upper portion of the transmission sleeve 38. The transmission sleeve 38 is fixed to the driving pulley 36 through the pulley seat 39, so that the transmission sleeve 38 can drive the driving pulley 36 to rotate. Spline shaft 2 33 includes a spline section 40 at its upper end, and the transmission sleeve 38 meshes with the spline section 40.

[0033] Because the bottom end of spline shaft 2 33 is connected to the drive motor 56, the height of spline shaft 2 33 remains constant. During the raising and lowering of the machine head assembly, the machine head transmission base 31 is driven to rise and fall, thereby driving the transmission sleeve 38 in the driving pulley 36 to rise and fall along the spline section 40 on spline shaft 2 33. The lifting range of the transmission sleeve 38 remains within the length of the spline section 40, so that the transmission sleeve 38 remains in meshing state with the spline section 40. Therefore, when spline shaft 2 33 rotates, the spline section 40 and transmission sleeve 38 can cooperate to drive the driving pulley 36 to rotate. The driving pulley 36 then drives the driven pulley 34 to rotate via the synchronous belt 41.

[0034] like Figure 8 As shown, a spline sleeve 44 is mounted on the upper portion of the driven pulley 34, and the spline sleeve 44 engages with the splines on the spline shaft 1 32. The driven pulley 34 drives the spline shaft 1 32 to rotate via the spline sleeve 44. A mounting sleeve 1 45 is mounted on the spline shaft 1 32, and is installed between the driven pulley 34 and the spline sleeve 44. A spring 2 46 is disposed between the mounting sleeve 1 45 and the spline sleeve 44. A bolt passes through the spline sleeve 44 and the mounting sleeve 1 45, and is screwed into the driven pulley 34. By adjusting the depth of the bolt screwed into the driven pulley 34, the distance between the spline sleeve 44 and the driven pulley 34 can be adjusted to accommodate different spline positions on the spline shaft 1 32, ensuring that the spline sleeve 44 can be mated with the splines on the spline shaft 1 32.

[0035] Furthermore, a bearing seat 42 is provided above the machine head cover 30. A rotating ring 43 is connected to the upper end of the spline shaft 1 32. The rotating ring 43 is limited in rotation within the bearing seat 42. The bearing seat 42 vertically limits the position of the spline shaft 1 32, and the spline shaft 1 32 rises and falls with the bearing seat 42. As the machine head transmission seat 31 rises and falls, the driven pulley 34 and the spline shaft 1 32 rise and fall synchronously.

[0036] A second mounting sleeve 48 is installed at the lower portion of the machine head transmission seat 31 through a mounting seat 49 , and the first spline shaft 32 passes through the second mounting sleeve 48 .

[0037] like Figure 7 As shown, a half body 50 is installed below the head transmission seat 31, and a scissor disk 52 is installed at the bottom of the half body 50. A plurality of gate knives 51 are installed on the upper part of the scissor disk 52. The spline shaft 1 32 is installed through the half body 50 and the scissor disk 52. The portion of the spline shaft 1 32 that passes through the scissor disk 52 is installed with a half disk 53. A limit ring is provided on the spline shaft 1 32 above the half disk 53, and the end of the spline shaft 1 32 is threadedly connected to a fixing screw 54. When the fixing screw 54 is tightened, it moves upward against the half disk 53, so that the upper end of the half disk 53 presses against the limit ring, thereby completing the fixation of the half disk 53. A plastic cap 55 is sleeved on the bottom of the half disk 53, which can cover the half disk 53 and the bottom end of the spline shaft 1 32.

[0038] A mounting sleeve three 59 is connected between the half body 50 and the machine head transmission seat 31 , and the spline shaft 1 32 is arranged through the mounting sleeve three 59 .

[0039] Furthermore, fixed disks 35 are mounted above and below the driven pulley 34. The outer diameter of the fixed disk 35 is larger than that of the driven pulley 34. Retaining rings 37 are mounted above and below the driving pulley 36. The outer diameter of the retaining ring 37 is larger than that of the driving pulley 36. The fixed disks 35 and retaining rings 37 limit the position of the synchronous belt 41, preventing it from coming off the driven pulley 34 and the driving pulley 36.

[0040] Furthermore, a positioning plate 47 is installed on the machine head transmission seat 31, and a guide rod 29 is connected to the upper part of the yarn guide disc 27. The guide rod 29 is set through the positioning plate 47. Through the cooperation of the positioning plate 47 and the guide rod 29, the guidance is realized only during the lifting process of the machine head component.
