[0043] An embodiment of the present invention discloses a drum paper threading machine, as Figure 1 shown in □16, including: a frame 1 arranged in a frame structure, on which a threading workbench 2, a wire supply mechanism 3, a threading mechanism 4, a wire clamping mechanism 5, and a wire cutting mechanism 6 are installed; the wire supply mechanism 3 is used to provide a working wire 33 for threading the drum paper 9; a first driving component 7 and a second driving component 8 are installed on the frame 1, the first driving component 7 is used to drive the threading mechanism 4 and the wire cutting mechanism 6 to perform synchronous lifting and lowering in the vertical direction, and the second driving component 8 is used to drive the wire clamping mechanism 5 to perform lifting and lowering movement in the vertical direction;

[0044] The threading workbench 2 includes a threading base 21, on which a first threading module 22 and a second threading module 23 are provided. On one side of the threading base 21, a telescopic cylinder 24 is installed for driving the second threading module 23 to approach or move away from the first threading module 22; a drum paper 9 is lapped on the first threading module 22 and the second threading module 23, and a first hole 91 and a second hole 92 are adjacently arranged on the drum paper 9; a movable block 25 is connected to the telescopic rod of the telescopic cylinder 24, the movable block 25 is movably embedded in the threading base 21, and the movable block 25 is fixedly connected to the second threading module 23;

[0045] The first threading module 22 is provided with a first threading groove 221, the second threading module 23 is provided with a second threading groove 231, the first threading groove 221 and the second threading groove 231 enclose a through threading groove, one end slot of the through threading groove communicates with the first hole 91, and the other end slot of the through threading groove communicates with the second hole 92;

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

[0047] It should be noted that the threading mechanism 4 drives the working wire 33 to move into the first hole 91, pass through the through threading groove and then pass out from the second hole 92; the wire clamping mechanism 5 clamps the end of the working wire 33 passing through the second hole 92; the wire cutting mechanism 6 cuts the working wire 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 the labor cost.

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

[0049] As Figures 1-4 shown in the figure, the numbers of the wire supply mechanism 3, the wire threading mechanism 4 and the buffer mechanism 10 are all set to two. In the specific implementation process, the numbers of the first holes 91 and the second holes 92 are both 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] As Figures 1-16 shown in the figure, the wire supply mechanism 3 includes a wire supply motor 31 installed on the frame 1. A wire supply frame 32 is installed on the output shaft of the wire supply motor 31. The working wire 33 is wound on the wire supply frame 32. It should be noted that by driving the wire supply frame 32 to rotate by the wire supply motor 31, the working wire 33 can be transported forward or retracted backward.

[0051] As Figures 1-11 shown in the figure, the wire threading mechanism 4 includes a wire threading frame 401. A connection wheel 402, a wire threading pipe 403 and a wire threading motor 404 are installed on the wire threading frame 401. A driving wheel 405 is installed on the output shaft of the wire threading motor 404. Two driven wheels 406 arranged side by side are rotatably connected to the frame 1. A wire threading belt 407 is wound around the driving wheel 405 and the two driven wheels 406;

[0052] The working wire 33 is successively in contact with the connection wheel 402 and the wire threading belt 407, and passes through the wire threading pipe 403. One end of the wire threading pipe 403 close to the wire threading workbench 2 is arranged in a vertical state.

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

[0054] As Figures 1-11As shown, a threading frame 401 is slidably connected with a sliding table 408. A limit cylinder 409 for driving the sliding table 408 to move is installed on the threading frame 401. The sliding table 408 is rotatably connected with a wire pressing wheel 410 that contacts the working wire 33. It should be noted that through the driving action of the limit cylinder 409, the wire pressing wheel 410 presses down to contact the working wire 33, facilitating the threading belt 407 to drive the working wire 33 to move.

[0055] As Figures 1-11 shown, the threading frame 401 is provided with a through groove communicating with the threading pipe 403. A limit block 411 embedded in the through groove is installed on the sliding table 408. The limit block 411 is used to limit the working wire 33 passing through the through groove. It should be noted that through the driving action of the limit cylinder 409, the wire pressing wheel 410 and the limit block 411 press down synchronously to contact and limit the working wire 33, facilitating the threading belt 407 to drive the working wire 33 into the threading pipe 403.

[0056] As Figure 1 and Figure 14 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 installed on the wire clamping cylinder 51. The second clamping frame 53 is slidably connected with the wire clamping cylinder 51. The wire clamping cylinder 51 is used to drive the second clamping frame 53 to approach or move away from the first clamping frame 52.

[0057] It should be noted that through the driving of the second driving component 8, the wire clamping mechanism 5 is moved to the wire clamping position, and the wire 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 end of the working wire 33. The number of the second clamping frames 53 is set to two, and the two second clamping frames 53 are distributed on the opposite sides of the first clamping frame 52.

[0058] As Figure 1 and Figure 14 shown, a first inclined surface 521 is provided at the bottom of the first clamping frame 52, and a second inclined surface 531 is provided at the bottom of the second clamping frame 53. It should be noted that due to the settings of the first inclined surface 521 and the second inclined surface 531, it is prevented that the first clamping frame 52 and the second clamping frame 53 damage the drum paper 9 when pressing down.

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

[0060] It should be noted that the first driving assembly 7 drives the wire cutting mechanism 6 to move to the wire cutting position. The first wire cutting cylinder 61 drives the second wire cutting cylinder 62 to move horizontally. The second wire cutting cylinder 62 drives two wire cutting blades 63 to approach each other to cut the working wire 33.

[0061] The specific steps of threading the drum paper 9 are as follows: The first driving assembly 7 drives the threading mechanism 4 to move downward to make the thread guide tube 403 close to the first hole 91. The threading motor 404 drives the threading belt 407 to move to make the end of the working wire 33 enter the first hole 91. After passing through the first wire groove 221 and the second wire groove 231, the end of the working wire 33 passes out from the second hole 92. Then, the second driving assembly 8 drives the wire clamping mechanism 5 to move downward to the wire clamping position. Since the first clamping bracket 52 and the second clamping bracket 53 play a clamping role, the first clamping bracket 52 and the second clamping bracket 53 clamp the end of the working wire 33. At this time, the first driving assembly 7 drives the wire cutting mechanism 6 to move upward to the wire cutting position. The first wire cutting cylinder 61 drives the second wire cutting cylinder 62 to move horizontally. The second wire cutting cylinder 62 drives two wire cutting blades 63 to approach each other to cut the working wire 33, thus realizing the threading process of the drum paper 9.

[0062] Working principle: The threading mechanism 4 drives the working wire 33 to move through the first hole 91, passes through the wire groove and passes out from the second hole 92. The wire clamping mechanism 5 clamps the end of the working wire 33 passing through the second hole 92. The wire cutting mechanism 6 cuts the working wire 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 the labor cost.

[0063] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill 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 manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
