The cutting tool 26 is arranged at the lower end of the movable tool holder 25 for cutting the beading line. The driving motor drives the eccentric rotating component to rotate through the gear box 27, thereby driving the movable tool holder 25 to move up and down, so as to realize the precise cutting of the beading line by the cutting tool 26.

[0070] The arrangement shaft includes an arrangement optical axis 31 and a threaded axis 32, which are arranged alternately. The ends of the arrangement optical axis 31 and the threaded axis 32 are connected to the transmission gear set 30, and are driven to rotate by the transmission gear set 30 to arrange the beads. The arrangement shaft is tilted and one end connected to the transmission gear set 30 is higher than the other end. This tilted setting helps the beads to automatically slide down and be arranged neatly under the combined action of gravity and the rotation of the arrangement shaft.

[0071] Combined with Figure 1 , 5 9. The auxiliary wire pressing mechanism includes an outer cover 33 and a wire pressing assembly 34. The wire pressing assembly 34 is arranged above the bead arrangement driving assembly, and the outer cover 33 surrounds the wire pressing assembly 34. The structure of the wire pressing assembly 34 is the same as that of the wire feeding assembly, and is used to press the bead threading wire.

[0072] Combined with Figure 12-14 The transport mechanism includes a transport fixed bracket 35, a rotating assembly, a suspension frame and a clamping assembly. The rotating assembly includes a rotating drive motor 36 and a rotating frame 37. The rotating drive motor 36 is fixed on the transport fixed bracket 35. The rotating frame 37 is connected to the power output end of the rotating drive motor 36 and rotates under the drive thereof. For the convenience of use, a speed change gear box 27 can be added to the power output end of the rotating drive motor 36, and the rotation speed can be adjusted by the speed change gear. The power output structure of the speed change gear box 27 is connected to the rotating shaft of the rotating frame 37, thereby driving the rotating frame 37 to rotate; in this way, by controlling the rotating drive motor 36, the rotation of the rotating frame 37 can be realized, thereby adjusting the working position of the clamping assembly.

[0073] The suspension frame is arranged in the rotating frame 37 and is rotatably connected to both sides thereof, and is used to suspend the clamping assembly. This design allows the suspension frame to rotate relative to the rotating frame 37, and in conjunction with the self-gravity of the clamping assembly, the clamping assembly is always kept parallel to the horizontal plane during the rotation of the rotating frame 37.

[0074] The clamping assembly includes a connecting frame plate 38, a clamp mounting plate 39, a clamp 40, and a clamping driving component 41. The connecting frame plate 38 is connected to the end of the suspension frame, the clamp mounting plate 39 is fixed on the connecting frame plate 38, the clamp 40 is arranged on the clamp mounting plate 39 and connected to the clamp driving assembly, and the clamp 40 clamps and releases the object under the drive of the clamp driving assembly.

[0075] The clamping components of the present invention can be arranged in several groups symmetrically about the suspension frame, and specifically, one group can be arranged symmetrically around the center, so as to clamp the two ends of the beaded product.

[0076] The clamping drive component 41 includes a clamp driving motor, a clamp driving eccentric wheel and a clamp push plate. The power output end of the clamp driving motor is connected to the clamp driving gear box 27, and the output end of the clamp driving gear box 27 is connected to the clamp driving eccentric wheel. A moving block is provided on one side of the clamp driving eccentric wheel, and the moving block is fixed on the clamp push plate. When the clamp driving motor is working, the clamp driving eccentric wheel is driven to rotate through the clamp driving gear box 27, and then the clamp push plate is driven to move, pushing the clamp 40 to clamp or release the object.

[0077] The clamp 40 includes a left clamp body, a right clamp body and a reset torsion spring. The left clamp body and the right clamp body are both rotatably connected to the clamp mounting plate 39. The reset torsion spring is arranged between the left clamp body and the right clamp body and its two ends are respectively connected to the left clamp body and the right clamp body. Under the action of the reset torsion spring, the left clamp body and the right clamp body can be automatically reset to achieve the clamping and release of the object.

[0078] In order to further improve the stability of clamping, the top of the right clamp body is higher than the left clamp body, and a downward extending push piece is provided at the lower end of the clamp push plate, which can contact the top of the right clamp body to drive the right clamp body to separate from the left clamp body, so as to separate the left clamp body from the right clamp body. When the clamp push plate drives the push piece to separate from the right clamp body, the left clamp body and the right clamp body are automatically closed and clamped under the drive of the reset torsion spring. This design makes the clamp 40 more stable when clamping objects and not easy to fall off.

[0079] In addition, a clamp mounting hole is provided on the side of the lower part of the right clamp body close to the left clamp body, and a removable extended clamp is provided in the clamp mounting hole. Since the right clamp body as a whole is moved upward relative to the left clamp body, the lower end of the right clamp body is lengthened by the extended clamp so that it can cooperate with the left clamp body for clamping.

[0080] In order to increase the clamping force and stability of the clamp 40, the middle parts of the left clamp body and the right clamp body are provided with mutually meshing protruding teeth. In this way, when the clamp 40 clamps an object, the protruding teeth can mesh with each other to improve the clamping stability.

[0081] In order to further improve the stability of the rotating mechanism, a stabilizing structure is provided on one side of the rotating frame 37, and the stabilizing structure includes a first pulley, a second pulley, and a belt connecting the two. The first pulley is arranged outside the rotating frame 37 and is coaxially connected to the rotating shaft of the rotating frame 37, and the second pulley is arranged on the same side as the first pulley and is coaxially connected to the suspension frame. This design can effectively prevent the rotating frame 37 from shaking during rotation, and improve the stability of the entire device.

[0082] In order to limit the rotation range of the rotating frame 37, a rotation limiter is provided at the end of the rotation axis of the rotating frame 37. By adjusting the position of the rotation limiter, the rotation angle of the rotating frame 37 can be controlled to avoid damage caused by excessive rotation. Specifically, in the present application, the rotating frame 37 is limited to rotate within the range of 0-180°.

[0083] In addition, the present invention further comprises a bead collection platform 42, which is arranged on one side of the support frame 1 and located on the side of the transfer mechanism for collecting the beads.

[0084] A beading process comprises the following steps:

[0085] Step S1: The wire feeding cam of the wire feeding assembly presses the bead threading wire;

[0086] Step S2: The positioning assembly, the bead threading assembly, and the wire feeding assembly move forward synchronously to send the positioning tube to the positioning block;

[0087] Step S3: When the bead threading line is a hard thread, the bead threading assembly and the thread feeding assembly move synchronously to thread the beads onto the bead threading tube, and at the same time, the bead threading tube is sent to the pressing and fixing position of the thread pressing cam of the thread pressing assembly;

[0088] Step S4: the wire feeding assembly moves forward alone to feed the bead threading wire 2 cm out of the bead threading tube;

[0089] Step S5: compressing the wire pressing cam of the wire pressing assembly, opening the wire feeding cam of the wire feeding assembly, and fixing the beading wire on the wire pressing block of the wire pressing cam of the wire pressing assembly;

[0090] Step S6: The positioning assembly, the wire feeding assembly, and the bead threading assembly move backward synchronously, leaving the bead thread inside the beads;

[0091] Step S7: The wire feeding cam of the wire feeding assembly is pressed, the wire cutting mechanism is started to cut the beading wire, and the transfer mechanism is started to clamp the two ends of the beading wire to clamp the product and transfer it to the beading collection table;

[0092] In step S3, when the beading thread is a soft thread, a wire feeding tube is installed on the wire feeding assembly, and the wire feeding tube is sleeved on the outside of the beading thread. The wire feeding assembly moves forward to drive the beading thread to move, and the wire feeding tube is inside the beading tube.

[0093] During the bead threading process when the bead threading tube moves forward, the bead threading wire moves inside the bead threading tube and synchronously with the bead threading wire. The present invention provides a specific structure for implementing the wire pressing by using a wire pressing cam. Those skilled in the art can change the wire pressing method according to actual needs. When the wire pressing structure is replaced with other existing structures, it should also be within the protection scope of the present application.

[0094] The specific implementation process of a bead threading machine and a bead threading process of the present invention is as follows:
