[0070] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0071] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0072] like Figure 1 As shown, the present embodiment provides an automatic hook loom, which is used to automatically hook a decorative loop of a thread such as a jade thread on a carrier ring 72, and the carrier ring 72 is generally a plastic ring. The automatic hook loom may include a carrier ring rotating mechanism, a hook mechanism and a wire feeding mechanism.

[0073] In this embodiment, the bearing ring rotating mechanism is used to clamp the bearing ring 72 and drive the bearing ring 72 to rotate around the center of the circle. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bearing ring rotating mechanism includes a first base plate 3 , two fixed clamping components 4 arranged opposite to each other on the first base plate 3 , and an adjustable clamping component 5 arranged on the first base plate 3 .

[0074] Specifically, the adjustable clamping component 5 is located on the midline of the line connecting the two fixed clamping components 4, the wire feeding bend 1 and the hook needle 2 are both arranged between the two fixed clamping components 4, and a threading hole 6 is arranged on the first substrate 3 between the two fixed clamping components 4. The wire passes upward from the threading hole 6 and enters the wire feeding bend 1 of the crochet mechanism.

[0075] The fixed clamping assembly 4 includes a sleeve 7 fixedly and vertically arranged on the first base plate 3, a rotating shaft rotatably arranged in the sleeve 7 along the axial direction of the sleeve 7, and a first clamp 8 rotatably installed on the top of the sleeve 7 through a bearing, the bottom of the first clamp 8 is connected to the top of the rotating shaft, and the bottom of the rotating shaft is installed with a driven synchronous wheel 9 after passing downward from the first base plate 3. The driven synchronous wheel 9 rotates, driving the rotating shaft in the sleeve 7 to rotate, thereby driving the first clamp 8 to rotate.

[0076] The adjustable clamping assembly 5 includes an inverted L-shaped mounting seat 10, a sliding seat 11 slidably mounted on the top of the mounting seat 10, an adjusting member 12 arranged at one end of the top of the mounting seat 10, and a second clamping member 13 rotatably mounted on the end of the mounting seat 10 away from the adjusting member 12 through a bearing. The bottom of the second clamping member 13 is connected to one end of a universal joint shaft 14, and the other end of the universal joint shaft 14 is also connected to a driven synchronous wheel 9 after passing through the bottom of the first substrate 3 downward. The universal joint shaft 14 is driven to rotate by the driven synchronous wheel 9, and the universal joint shaft 14 drives the second clamping member 13 to rotate.

[0077] The adjusting member 12 is connected to one end of the sliding seat 11, and is used to drive the sliding seat 11 to slide along the top of the mounting seat 10 to make the second clamping member 13 approach or move away from the first clamping member 8. When the second clamping member 13 approaches the first clamping member 8, the bearing ring 72 can be clamped on the second clamping member 13 and the two first clamping members 8, and when the second clamping member 13 and the first clamping member 8 rotate, the bearing ring 72 can be driven to rotate. The first clamping member 8 and the second clamping member 13 are arranged in the same horizontal plane, so that the clamped bearing ring 72 can be kept in a horizontal state, and the bearing ring 72 can be prevented from tilting, which may cause the crocheted decorative coil to fail to meet the quality requirements.

[0078] A first motor 15 is provided at the bottom of the first substrate 3, and an active synchronous wheel 16 is installed on the first motor 15, and the active synchronous wheel 16 is connected to three driven synchronous wheels 9 through a synchronous belt. The first motor 15 drives the active synchronous wheel 16 to rotate, and the active synchronous wheel 16 drives the three driven synchronous wheels 9 to rotate in the same direction at the same time through the synchronous belt, so as to drive the bearing ring 72 to rotate. In order to accurately control the rotation speed of the bearing ring 72, the first motor 15 can adopt a servo motor or a stepping motor.

[0079] In order to provide stable support for the bearing ring 72 with a larger diameter, the bearing ring rotating mechanism also includes auxiliary clamping components 17 arranged opposite to each other on both sides of the first substrate 3. The auxiliary clamping component 17 includes a first column 18 and a third clamping component 80 rotatably mounted on the top of the first column 18. The third clamping component 80, the first clamping component 8 and the second clamping component 13 are all arranged in the same horizontal plane. The bottom end of the first column 18 is adjustably mounted in an adjustment hole 19 on the first substrate 3 by bolts. The adjustment hole 19 is in the shape of a long strip and is perpendicular to the center line of the line connecting the two fixed clamping components 4. The first column 18 slides along the adjustment hole 19 to adjust the distance between the two auxiliary clamping components 17. By adjusting the distance between the two auxiliary clamping components 17, it is used to adapt to the load-bearing requirements of bearing rings 72 of different sizes.

[0080] Specifically, the first clamp 8, the second clamp 13 and the third clamp 80 have the same structure. The first clamp 8 includes a disc 20 and a truncated cone 21 concentrically arranged on the top of the disc 20, the lower bottom surface of the truncated cone 21 is smaller than the upper bottom surface, and a connecting rod 22 extending downward is concentrically arranged at the bottom of the disc 20. The outer edge of the bearing ring 72 is connected to the connection between the truncated cone 21 and the disc 20. It can be understood that the connecting rod 22 of the first clamp 8 is fixedly connected to the top of the rotating shaft in the sleeve 7, the connecting rod 22 of the second clamp 13 is connected to the top of the universal transmission shaft 14, and the connecting rod 22 of the third clamp 80 is connected to the bearing at the top of the first column 18.

[0081] In this embodiment, the adjusting member 12 can be a push-pull type quick clamp, which is convenient and quick to operate. The sliding seat 11 is slidably connected to the top of the mounting seat 10 through a linear slide rail.

In this way, when the adjustment member 12 pushes the sliding seat 11 to slide and drives the second clamping member 13 to translate, the length of the connecting shaft 25 extending out of the sleeve 24 can be adaptively changed without affecting the shaft driving the second clamping member 13 to rotate.

[0083] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12As shown, the crocheting mechanism includes an inverted L-shaped wire feeding bend 1, a hook 2 and a driving assembly, and the vertical section of the wire feeding bend 1 and the hook 2 are both installed on the driving assembly. The wire feeding bend 1 and the hook 2 are arranged opposite to each other, and the wire outlet port on the top of the wire feeding bend 1 is arranged toward the hook 2, and the wire material enters from the bottom of the wire feeding bend 1 and passes out from the top of the wire feeding bend 1. The driving assembly is used to drive the wire feeding bend 1 to swing back and forth within a first preset angle range on a vertical plane. The driving assembly is also used to drive the hook 2 to approach or move away from the wire feeding bend 1, and drive the hook 2 to reciprocate axially within a second preset angle range to cooperate with the swing of the wire feeding bend 1. The driving assembly is also used to drive the hook 2 to reciprocate up and down synchronously with the wire feeding bend 1. Specifically, a complete crocheting process is as follows Figure 16-Figure 21 shown.

[0084] In this embodiment, the driving assembly includes a bending tube driving module, a hook driving module, and a coordination module for coordinating the movements of the bending tube driving module and the hook driving module.

[0087] The coordination module includes an up-and-down motion coordination unit, a pipe bending swing coordination unit, a hook rotation coordination unit, a hook advance-and-retreat coordination unit, and a second motor 73. The up-and-down motion coordination unit, the pipe bending swing coordination unit, and the hook advance-and-retreat coordination unit are all connected to the second motor by transmission, and the up-and-down motion coordination unit, the pipe bending swing coordination unit, and the hook advance-and-retreat coordination unit are driven by the second motor 73 to move synchronously.

[0088] The up-down motion coordination unit is connected to the first mounting rod 26 and the second mounting rod 30 in a transmission connection, and is used to drive the first mounting rod 26 and the second mounting rod 30 to swing up and down synchronously within a preset range. The elbow swing coordination unit is connected to the first mounting rod 26 in a transmission connection, and is used to drive the first mounting rod 26 to reciprocate axially within a first preset angle range.

[0090] One end of the driving plate 34 is rotatably connected to the top of the third column 36, and the bottom of the third column 36 is fixedly connected to the second base plate 29. The driving plate 34 is located on one side of the driving column 33, and the plate surface is arranged longitudinally.

[0091] A driving groove 37 is provided on the outer peripheral wall of the driving column 33, and the driving groove 37 is provided through the outer peripheral wall surface of the driving column 33. A pin shaft 38 is provided on the driving plate 34, and one end of the pin shaft 38 is inserted into the driving groove 37 and contacts the inner wall of the driving groove 37. When the driving column 33 rotates, the pin shaft 38 moves along the track of the driving groove 37, and the pin shaft 38 drives the driving plate 34 to rotate up and down around the connection with the third column 36 following the track of the driving groove 37.

[0092] like Fig.13 As shown, the driving plate 34 has two connecting holes 39 spaced apart and arranged in parallel, and a connecting block 40 is sleeved on the middle part of the first mounting rod 26 and the middle part of the second mounting rod 30. The connecting block 40 on the second mounting rod 30 is slidably connected to the second mounting rod 30, so as not to affect the axial reciprocating sliding of the second mounting rod 30 along the second mounting rod 30.

[0093] like Fig. 9 As shown, the two connecting blocks 40 are connected with screw rods 41, and the two screw rods 41 are respectively inserted into the corresponding connecting holes 39. When the driving plate 34 rotates up and down, the first mounting rod 26 and the second mounting rod 30 are driven to rotate up and down synchronously through the screw rods 41. The first mounting rod 26 rotates around the connection between the U-shaped frame and the second column 28, and the second mounting rod 30 rotates around the connection between the second mounting block 31 and the U-shaped frame.
