[0045] The first threading module 22 is provided with a first threading groove 221, and the second threading module 23 is provided with a second threading groove 231. The first threading groove 221 and the second threading groove 231 are enclosed to form a threading groove, one end notch of the threading groove is communicated with the first hole 91, and the other end notch of the threading groove is communicated with the second hole 92;

[0046] The threading mechanism 4 is used to drive the working line 33 to move through the first hole 91, through the wire groove and out of the second hole 92; the wire clamping mechanism 5 clamps the thread end of the working line 33 passing through the second hole 92; the wire cutting mechanism 6 is used to cut the working line 33 on the threading mechanism 4. In this embodiment, the first driving assembly 7 includes a first slide 71 slidably connected to the frame 1, and the threading mechanism 4 and the wire cutting mechanism 6 are both installed on the first slide 71, and the frame 1 is equipped with a first driving cylinder 72 for driving the first slide 71 to rise and fall in the vertical direction. The second driving assembly 8 includes a second slide 81 slidably connected to the frame 1, and the frame 1 is equipped with a second driving cylinder 82 for driving the second slide 81 to rise and fall in the vertical direction.

[0047] It should be noted that the working line 33 is driven by the threading mechanism 4 to move through the first hole 91, through the wire groove and out of the second hole 92; the wire clamping mechanism 5 clamps the thread end of the working line 33 passing through the second hole 92; the wire cutting mechanism 6 cuts the working line 33 on the threading mechanism 4, thereby providing a drum paper threading machine, realizing the automatic threading of the drum paper 9, improving the threading efficiency of the drum paper 9, and reducing labor costs.

[0048] like Figure 1 and Fig.16As shown, it also includes a buffer mechanism 10 located between the wire supply mechanism 3 and the threading mechanism 4. The buffer mechanism 10 keeps a certain tension on the working wire 33 passing through the buffer mechanism 10, so that the working wire 33 enters the threading mechanism 4 in the vertical direction. In the specific implementation process, the buffer mechanism 10 includes a lead-in platform 101 installed on the frame 1, and the lead-in platform 101 is installed with a first lead-in wheel 102, a second lead-in wheel 103 and a third lead-in wheel 104. The first lead-in wheel 102 and the third lead-in wheel 104 are arranged side by side, and the working wire 33 contacts the first lead-in wheel 102, the second lead-in wheel 103 and the third lead-in wheel 104 in sequence, and the working wire 33 is led out from the third lead-in wheel 104 to the threading mechanism 4.

[0049] like Figure 1-4 As shown, the number of the wire feeding mechanism 3, the threading mechanism 4 and the buffer mechanism 10 is set to two. In the specific implementation process, the number of the first hole 91 and the second hole 92 is set to two, the two first holes 91 are arranged side by side, and the two second holes 92 are arranged side by side.

[0050] like Figure 1-16 As shown, the wire feeding mechanism 3 includes a wire feeding motor 31 mounted on the frame 1, a wire feeding frame 32 is mounted on the output shaft of the wire feeding motor 31, and a working wire 33 is wound on the wire feeding frame 32. It should be noted that the wire feeding frame 32 is driven to rotate by the wire feeding motor 31, so that the working wire 33 can be transported forward or recovered backward.

[0051] like Figure 1-11 As shown, the threading mechanism 4 includes a threading frame 401, on which a wiring wheel 402, a threading tube 403 and a threading motor 404 are installed, and a driving wheel 405 is installed on the output shaft of the threading motor 404. The threading frame 1 is rotatably connected to two driven wheels 406 arranged side by side, and a threading belt 407 is wound around the driving wheel 405 and the two driven wheels 406;

[0052] The working wire 33 contacts the wiring wheel 402 and the threading belt 407 in sequence, and passes through the threading tube 403. The threading tube 403 is arranged in a vertical state at one end close to the threading workbench 2.

[0053] It should be noted that the driving wheel 405 is driven to rotate by the threading motor 404; since the threading belt 407 is wound around the driving wheel 405 and the two driven wheels 406, the threading belt 407 is driven to move, so that the working line 33 moves forward along the threading tube 403, facilitating the threading operation.

[0054] like Figure 1-11As shown, the threading frame 401 is slidably connected to a sliding platform 408, and a limiting cylinder 409 for driving the sliding platform 408 to move is installed on the threading frame 401. The sliding platform 408 is rotatably connected to a pressing wheel 410 that contacts the working line 33. It should be noted that through the driving action of the limiting cylinder 409, the pressing wheel 410 is pressed down to contact the working line 33, so that the threading belt 407 drives the working line 33 to move.

[0055] like Figure 1-11 As shown, the threading frame 401 is provided with a through slot communicating with the threading tube 403, and a limit block 411 embedded in the through slot is installed on the sliding platform 408, and the limit block 411 is used to limit the working line 33 passing through the through slot. It should be noted that, through the driving action of the limit cylinder 409, the pressing wheel 410 and the limit block 411 are pressed down synchronously to contact and limit the working line 33, so that the threading belt 407 drives the working line 33 into the threading tube 403.

[0056] like Figure 1 and Fig.14 As shown, the wire clamping mechanism 5 includes a wire clamping cylinder 51, a first clamping frame 52 and a second clamping frame 53. The first clamping frame 52 is fixedly mounted on the wire clamping cylinder 51, and the second clamping frame 53 is slidably connected to the wire clamping cylinder 51. The wire clamping cylinder 51 is used to drive the second clamping frame 53 to move closer to or away from the first clamping frame 52.

[0057] It should be noted that the second driving assembly 8 drives the clamping mechanism 5 to move to the clamping position, and the clamping cylinder 51 drives the second clamping frame 53 to approach the first clamping frame 52; the first clamping frame 52 and the second clamping frame 53 play a clamping role, and the first clamping frame 52 and the second clamping frame 53 clamp the thread end of the working line 33. The number of the second clamping frames 53 is set to two, and the two second clamping frames 53 are distributed on opposite sides of the first clamping frame 52.

[0058] like Figure 1 and Fig.14 As shown, the first clamping frame 52 has a first inclined surface 521 at the bottom, and the second clamping frame 53 has a second inclined surface 531 at the bottom. It should be noted that the first inclined surface 521 and the second inclined surface 531 prevent the drum paper 9 from being damaged when the first clamping frame 52 and the second clamping frame 53 are pressed down.

[0059] like Figure 1 and Fig.15 As shown, the thread trimming mechanism 6 includes a first thread trimming cylinder 61 and a second thread trimming cylinder 62, the second thread trimming cylinder 62 is slidably connected to two thread trimming blades 63, the first thread trimming cylinder 61 is used to drive the second thread trimming cylinder 62 to move in the horizontal direction, and the second thread trimming cylinder 62 is used to drive the two thread trimming blades 63 to slide relatively. The thread trimming mechanism 6 is located below the threading mechanism 4.

[0060] It should be noted that the first driving assembly 7 drives the thread trimming mechanism 6 to move to the thread trimming position, the first thread trimming cylinder 61 drives the second thread trimming cylinder 62 to move in the horizontal direction, and the second thread trimming cylinder 62 drives the two thread trimming blades 63 to approach each other to cut the working line 33.

[0061] The specific steps of threading the drum paper 9 are as follows: the first drive component 7 drives the threading mechanism 4 to move downward, so that the threading tube 403 is close to the first hole 91, and the threading motor 404 drives the threading belt 407 to move, so that the thread end of the working line 33 enters the first hole 91, and after passing through the first threading groove 221 and the second threading groove 231, the thread end of the working line 33 passes through the second hole 92; then, the second drive component 8 drives the clamping mechanism 5 to move downward to the clamping position, because the first clamping frame 52 and the second clamping frame 53 play a clamping role, the first clamping frame 52 and the second clamping frame 53 clamp the thread end of the working line 33; at this time, the first drive component 7 drives the cutting mechanism 6 to move upward to the cutting position, the first cutting cylinder 61 drives the second cutting cylinder 62 to move in the horizontal direction, and the second cutting cylinder 62 drives the two cutting blades 63 to approach each other to cut the working line 33, thereby realizing the threading process of the drum paper 9.

[0062] Working principle: the threading mechanism 4 drives the working line 33 to move through the first hole 91, through the wire groove and out from the second hole 92; the wire clamping mechanism 5 clamps the thread end of the working line 33 passing through the second hole 92; the wire cutting mechanism 6 cuts the working line 33 on the threading mechanism 4, thereby providing a drum paper threading machine, realizing the automatic threading of the drum paper 9, improving the threading efficiency of the drum paper 9, and reducing labor costs.

[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
