When the wide paper is cut, the cutter of the cutting device firstly cuts the wide paper into a plurality of paper tape strips with the same width, and at the moment, the plurality of paper tape strips cut by the cutter are separated from each other, but the distance between the adjacent paper tape strips is small. In order to facilitate the subsequent use of the paper tapes on the winding drum, when a plurality of paper tapes are wound on the winding drum, a certain distance is required between two adjacent paper tapes, so that after wide paper is cut off by the cutter, a separating device is required to guide the paper tapes during the conveying process of the paper tapes, and the two adjacent paper tapes are separated by a certain distance.

In this embodiment, the deviation correcting component 3 includes a left deviation correcting member 32 and a right deviation correcting member 33, the tops of the left deviation correcting member 32 and the right deviation correcting member 33 are both connected with the connecting shaft 4, the bottoms of the left deviation correcting member 32 and the right deviation correcting member 33 are both provided with a limiting half hole 328, the limiting half hole 328 of the left deviation correcting member 32 and the limiting half hole 328 of the right deviation correcting member 33 form a limiting channel 31, the distance between the left deviation correcting member 32 and the right deviation correcting member 33 is adjustable, and the specific effect is shown in fig. 1 and fig. 2. Each deviation rectifying component 3 consists of a left deviation rectifying part 32 and a right deviation rectifying part 33, the tops of the left deviation rectifying part 32 and the right deviation rectifying part 33 are connected with the connecting shaft 4, the bottoms of the left deviation rectifying part 32 and the right deviation rectifying part 33 are respectively provided with a limiting half hole 328, and the limiting half hole 328 of the left deviation rectifying part 32 and the limiting half hole 328 of the right deviation rectifying part 33 form a complete limiting channel 31. The distance between the two limit half holes 328 forming a complete limit channel 31 is adjusted by adjusting the distance between the left deviation correcting part 32 and the right deviation correcting part 33 on the connecting shaft 4, so that the width of the limit channel 31 is adjusted.

In this embodiment, the left deviation rectifying member 32 and the right deviation rectifying member 33 both include a hanging ring 321 sleeved on the connecting shaft 4, a limiting block 322 provided with a limiting half hole 328, and a connecting rod member connecting the hanging ring 321 and the limiting block 322, and the specific effects are shown in fig. 3. The left deviation correcting piece 32 and the right deviation correcting piece 33 are identical in structure and respectively comprise a hanging ring 321, a limiting block 322 and a connecting rod piece, the hanging ring 321 is sleeved on the connecting shaft 4, the top of the limiting block 322 is connected with the hanging ring 321 through the connecting rod piece, a limiting half hole 328 is arranged at the bottom of the limiting block 322, the hanging ring 321 moves on the connecting shaft 4, the distance between the limiting half hole 328 of the left deviation correcting piece 32 and the limiting half hole 328 of the right deviation correcting piece 33 is adjusted, and therefore width adjustment of the limiting channel 31 is achieved.

It is foreseen that: because the left deviation rectifying part 32 and the right deviation rectifying part 33 are sleeved on the connecting shaft 4 through the hanging ring 321, the left deviation rectifying part 32 and the right deviation rectifying part can axially move along the connecting shaft 4 and can also circumferentially rotate around the connecting shaft 4. When the slitting equipment slits wide paper, the width and the number of slit paper tapes are different according to the specifications of different products. In the application, only when the connecting rod member vertically extends downwards on the connecting shaft 4, the limiting passage 31 formed by the limiting half hole 328 of the left deviation correcting member 32 and the limiting half hole 328 of the right deviation correcting member 33 can limit the paper tape, so that when the number of the cut paper tapes is reduced and the deviation correcting assemblies 3 are not needed, the left deviation correcting member 32 or the right deviation correcting member 33 in excess can rotate on the connecting shaft 4 through the hanging ring 321, the left deviation correcting member 32 or the right deviation correcting member 33 in excess circumferentially rotate on the connecting shaft 4 by a certain angle, the paper tape does not pass through the limiting half hole 328 of the left deviation correcting member 32 or the right deviation correcting member 33 when passing, and the left deviation correcting member 32 or the right deviation correcting member 33 can not obstruct the transmission of the paper tapes; when the number of the cut paper strips is increased, the left deviation correcting pieces 32 or the right deviation correcting pieces 33 with corresponding number are rotated circumferentially along the connecting shaft 4, and the connecting rod pieces vertically extend downwards on the connecting shaft 4, so that the number of the limiting channels 31 formed by the limiting half holes 328 of the left deviation correcting pieces 32 and the limiting half holes 328 of the right deviation correcting pieces 33 is matched with the number of the paper strips.

In the embodiment, the limiting half-hole 328 is surrounded by an upper limiting plate 3281, a lower limiting plate 3282 and a side limiting plate 3283, and an arc-shaped chamfer 3284 is arranged on the inner sides of the upper limiting plate 3281, the lower limiting plate 3282 and the side limiting plate 3283, and the specific effect is shown in fig. 4. The half-hole 328 is surrounded by an upper limiting plate 3281, a lower limiting plate 3282, and a side limiting plate 3283, and one side of the half-hole 328 is opened. Therefore, the limit half-hole 328 of the left deviation correcting element 32 is surrounded by the upper limit plate 3281, the lower limit plate 3282 and the left side limit plate 3283, and the right side thereof is open, and the limit half-hole 328 of the right deviation correcting element 33 is surrounded by the upper limit plate 3281, the lower limit plate 3282 and the right side limit plate 3283, and the left side thereof is open. The right opening of the limiting half hole 328 of the left deviation correcting member 32 is opposite to the left opening of the limiting half hole 328 of the right deviation correcting member 33, so that the limiting half hole 328 of the left deviation correcting member 32 and the limiting half hole 328 of the right deviation correcting member 33 can form a limiting channel 31 for the paper supply tape to pass through.

It is foreseen that: when the limiting channel 31 limits the passing paper tape, if the paper tape deviates, the side limiting plate 3283 of the left deviation correcting part 32 and the side limiting plate 3283 of the right deviation correcting part 33 abut against the two sides of the paper tape, so that the paper tape is guided, and the deviation of the paper tape is prevented. Under the tension of the conveying, the paper tape may abut against the upper and lower limiting plates 3281 and 3282 of the left and right deviation correcting members 32 and 33. Whether the side limiting plate 3283 abuts against the two sides of the paper tape strip or the upper limiting plate 3281 and the lower limiting plate abut against the upper side face and the lower side face of the paper tape strip respectively, the paper tape strip may be damaged or broken, and the winding and the use of the paper tape strip are influenced. Therefore, in the present application, the inner sides of the upper limiting plate 3281, the lower limiting plate 3282 and the side limiting plate 3283 are all provided with an arc-shaped chamfer 3284, so that the paper tape strip is prevented from being damaged or broken when the upper limiting plate 3281, the lower limiting plate 3282 and the side limiting plate 3283 abut against the paper tape strip.

In the embodiment, the length of the lower limiting plate 3282 is greater than that of the upper limiting plate 3281, as shown in fig. 4. The width of the limiting channel 31 can be increased by increasing the distance between the left deviation correcting piece 32 and the right deviation correcting piece 33, but the width is the minimum width which can be adjusted by the limiting channel 31 when the upper limiting plate 3281 of the left deviation correcting piece 32 is abutted with the upper limiting plate 3281 of the right deviation correcting piece 33 or the lower limiting plate 3282 of the left deviation correcting piece 32 is abutted with the lower limiting plate 3282 of the right deviation correcting piece 33. In the application, the length of the lower limiting plate 3282 is set to be greater than that of the upper limiting plate 3281, so that when the limiting channel 31 is in the minimum width, the lower limiting plate 3282 of the left deviation correcting part 32 abuts against the lower limiting plate 3282 of the right deviation correcting part 33, the upper limiting plate 3281 of the left deviation correcting part 32 is still separated from the upper limiting plate 3281 of the right deviation correcting part 33 by a certain distance, and therefore through the space between the upper limiting plate 3281 of the left deviation correcting part 32 and the upper limiting plate 3281 of the right deviation correcting part 33, the end part of the paper tape can be conveniently pulled to pass through the limiting channel 31 formed by the limiting half holes 328 of the left deviation correcting part 32 and the limiting half holes 328 of the right deviation correcting part 33, and the use of the device is more convenient and rapid.

In this embodiment, the link member includes an upper link 323 fixedly connected to the hanging ring 321, and a connecting elastic sheet 324 for connecting the upper link 323 and the limiting block 322, as shown in fig. 3. The connecting rod piece comprises an upper connecting rod 323 and a connecting elastic sheet 324, the top of the upper connecting rod 323 is fixedly connected with the hanging ring 321, and the connecting elastic sheet 324 connects the top of the limiting block 322 with the bottom of the upper connecting rod 323. The reason that the connecting elastic piece 324 is arranged in the middle of the connecting rod part is that a certain tension exists in the process of backward conveying of the paper tape, if the left deviation correcting part 32 and the right deviation correcting part 33 are rigid parts, the paper tape passes through the limiting channel 31 formed by the limiting half hole 328 of the left deviation correcting part 32 and the limiting half hole 328 of the right deviation correcting part 33, and the limiting channel 31 can possibly tear the paper tape under the action of the conveying tension, so that the rolling of the paper tape is influenced.

And set up one section at connecting rod spare middle part and connect shell fragment 324, connect shell fragment 324 and have certain elastic deformation ability, therefore the paper tape when transfer process produces great tension, connect shell fragment 324 can produce and warp to buffering the transmission tension on the paper tape, preventing that spacing passageway 31 from tearing the paper tape apart, and then make the result of use of this device better, the practicality is stronger. When the transmission tension on the paper tape strip is reduced, the connecting elastic sheet 324 restores the original shape under the action of the elasticity of the connecting elastic sheet.

In this embodiment, the connecting elastic sheet 324 is disposed on the top of the limiting block 322, the bottom of the upper connecting rod 323 is provided with an insertion groove 3231 for the connecting elastic sheet 324 to be inserted, the connecting elastic sheet 324 is axially provided with a plurality of first through holes 3241, the upper connecting rod 323 is provided with two second through holes 3232 which are oppositely disposed and respectively communicate two sides of the insertion groove 3231 with the outside, the connecting rod further includes a first bolt 325, one end of which sequentially penetrates through one second through hole 3232, one first through hole 3241 and the other second through hole 3232, and a nut 326, one end of which sequentially penetrates through one second through hole 3232, one first through hole 3241 and the other second through hole 3232 with the first bolt 325, and the specific effect is shown in fig. 3. The connecting elastic sheet 324 is arranged at the top of the limiting block 322, the bottom of the upper connecting rod 323 is provided with an inserting groove 3231, the connecting elastic sheet 324 is axially provided with a plurality of first through holes 3241, the upper connecting rod 323 is provided with two second through holes 3232 which are oppositely arranged, two sides of the inserting groove 3231 are communicated with the outside through the two second through holes 3232, one end of the connecting elastic sheet 324, which is far away from the connecting with the limiting block 322, is inserted into the inserting groove 3231, the central axis of one first through hole 3241 is overlapped with the central axes of the two second through holes 3232, one end of the first bolt 325 sequentially penetrates through one second through hole 3232, one first through hole 3241 and the other second through hole 3232, and the nut 326 and the first bolt 325 sequentially penetrate through one end of one second through hole 3232, one first through hole 3241 and the other second through hole 3232 to be screwed, so that the connecting elastic sheet 324 is fixedly connected with the upper connecting rod 323.

The arrangement is that when the end of the elastic connecting piece 324 far away from the end connected with the limiting block 322 is inserted into the insertion groove 3231, the insertion depth of the elastic connecting piece 324 in the insertion groove 3231 can be adjusted by the central axes of the first through hole 3241 and the two second through holes 3232 at different axial positions of the elastic connecting piece being overlapped with the central axes of the two second through holes 3232, so as to adjust the height of the limiting channel 31. The paper tape passes through from the top of bearing roller 2 earlier, passes from spacing passageway 31 again, and the high fixed of bearing roller 2 on support frame 1 through the height of adjusting spacing passageway 31, can make the difference in height between spacing passageway 31 and the bearing roller 2 change to make spacing passageway 31 when leading the paper tape, also can adjust the tension of paper tape, and then make the practicality of this device stronger.

In this embodiment, the lifting ring 321 is provided with a threaded hole 3211, and the left deviation correcting member 32 and the right deviation correcting member 33 further include a second bolt 327 having one end penetrating through the threaded hole 3211 and abutting against the connecting shaft 4, which is shown in fig. 3 and 5. In this application, the hanging ring 321 is sleeved on the connecting shaft 4, so that the left deviation correcting member 32 and the right deviation correcting member 33 can perform axial movement along the connecting shaft 4 and can also perform circumferential rotation around the connecting shaft 4. However, when the connecting rod extends vertically downward on the connecting shaft 4, and the paper tape is guided by the limiting channel 31 formed by the limiting half-hole 328 of the left deviation correcting element 32 and the limiting half-hole 328 of the right deviation correcting element 33, in order to prevent the paper tape from being driven to change the positions of the left deviation correcting element 32 and the right deviation correcting element 33 on the connecting shaft 4 under the action of the conveying tension of the paper tape, the left deviation correcting element 32 and the right deviation correcting element 33 cannot achieve a good limiting effect on the paper tape. Therefore, when the left deviation correcting piece 32 and the right deviation correcting piece 33 guide the paper tape, the left deviation correcting piece 32 and the right deviation correcting piece 33 need to be fixed on the connecting shaft 4, so that the limiting effect of the left deviation correcting piece 32 and the right deviation correcting piece 33 on the paper tape is ensured.

In addition, in the present application, the number of the limiting channels 31 for guiding the paper tapes can be adjusted according to the number of the paper tapes, and the left deviation correcting member 32 or the right deviation correcting member 33 in excess number can rotate on the connecting shaft 4 in the circumferential direction by a certain angle, so that the connecting rod member does not extend vertically and downwardly on the connecting shaft 4, but forms a certain included angle with the connecting shaft 4, and further the paper tapes do not pass through the limiting half-holes 328 of the left deviation correcting member 32 or the right deviation correcting member 33, and the left deviation correcting member 32 or the right deviation correcting member 33 does not hinder the transmission of the paper tapes. In order to prevent the left deviation rectifying part 32 or the right deviation rectifying part 33 which forms a certain included angle with the connecting shaft 4 from rotating on the connecting shaft 4 in the circumferential direction by a certain angle, the left deviation rectifying part 32 or the right deviation rectifying part 33 is automatically restored to be in a state of extending vertically and downwards on the connecting shaft 4 under the action of self gravity, and after the left deviation rectifying part 32 or the right deviation rectifying part 33 rotates on the connecting shaft 4 in the circumferential direction by a certain angle, the left deviation rectifying part 32 or the right deviation rectifying part 33 also needs to be fixed.

Therefore, in the present application, the hanging ring 321 is provided with a threaded hole 3211, and when the hanging ring 321 is sleeved on the connecting shaft 4, the hanging ring 321 is screwed with the threaded hole 3211 through the second bolt 327 and penetrates through the threaded hole 3211 to abut against the connecting shaft 4, so that the hanging ring 321 can be fixed on the connecting shaft 4.
