If the first and second are described only for the purpose of distinguishing technical features, they should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0045] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0046] The following refers to Figures 1 to 3 to describe in detail the blanking method of the first aspect of the present invention.

[0047] Refer to Figure 1 , according to the blanking method of the embodiment of the first aspect of the present invention, includes but is not limited to the following steps:

[0048] Step S200: Cut the connection between the first section and the second section of the cotton pads. Among them, at least part of the first section is wound around the reel to form a material roll, and the second section is to be wound around the reel;

[0049] Step S300: Drive the reel to continue rotating a certain angle along the winding direction of the first section, so that the movable end of the first section is completely wound on the material roll;

[0050] Step S400: Adhere and fix the movable end of the first section on the material roll.

[0051] It should be noted that after the cotton pads are wound around the reel to form a material roll, the reel needs to be blanked, and another new reel is replaced to continue winding the remaining cotton pads. However, after cutting the first section and the second section of the cotton pads, the first section cannot be completely wound around the reel. Under the action of gravity, the movable end of the first section will droop. In this case, if the reel wound with the first section is directly transported or stored,

[0052] Under the action of external force, the cotton pads on the reel will come loose.

[0053] It can be understood that in the blanking method of the present application, first, the connection between the first section and the second section of the cotton pad is cut off. Then, the reel is driven to continue rotating a certain angle along the winding direction of the first section, so that the movable end of the first section is completely wound on the material roll. Next, the movable end of the first section is adhered and fixed on the material roll, so that the movable end of the material roll on the reel can be fixed on the material roll, thereby reducing the probability that the cotton pads wound on the reel automatically unwind.

[0054] In some embodiments of the present invention, referring to Figure 1 , before step S200, there are also steps including but not limited to the following:

[0055] Step S100: Drive the reel to move in a direction away from the second section to tension the junction of the first section and the second section.

[0056] It can be understood that by driving the reel to move in a direction away from the second section, the junction of the first section and the second section can be tensioned, facilitating subsequent cutting of the junction of the first section and the second section.

[0057] In some embodiments of the present invention, referring to Figure 2 , in step S200, there are also steps including but not limited to the following:

[0058] Step S210: Fix the first section and the second section respectively;

[0059] Step S220: Extrude the junction of the first section and the second section to cut off the connection between the first section and the second section;

[0060] Step S230: Release the fixation of the first section and the second section.

[0061] It can be understood that before cutting off the connection between the first section and the second section, by fixing the first section and the second section respectively, the deformation of the first section and the second section during the cutting process can be reduced;

[0062] It can be understood that by fixing the first section and the second section, the junction of the first section and the second section can be cut more smoothly under the extrusion effect, thereby reducing the cutting difficulty between the first section and the second section.

[0063] In some embodiments of the present invention, referring to Figure 3 , in step S400, there are also steps including but not limited to the following:

[0064] Step S410: Remove the label from the bottom film;

[0065] Step S420: Drive the label to adhere and fix the movable end of the first section on the material roll.

[0066] It can be understood that by using the label to complete the fixation of the active end of the first section on the material roll, the pasting of the label on the material roll can be synchronously completed, reducing the processes of the entire blanking method and saving time and effort.

[0067] The following refers to Figures 4 to 9 to describe in detail the unwinding device according to the second aspect of the embodiments of the present invention.

[0068] Referring to Figure 4 , the unwinding device provided according to the second aspect of the embodiments of the present invention includes a winding module 100, a cutting module 200, an adjustment module 300, and an adhesion module 400; the winding module 100 is used for winding the cotton pads so that at least a part of the first section of the cotton pads is wound around the reel, and the cotton pads further include a second section connected to the first section, and the second section is to be wound around the reel; the cutting module 200 is used for cutting the connection between the first section and the second section of the cotton pads; the adjustment module 300 is used for driving the reel to continue to rotate a certain angle along the winding direction of the first section so that the active end of the first section is completely wound on the material roll; the adhesion module 400 is used for adhering and fixing the active end of the first section on the material roll.

[0069] It can be understood that in the unwinding device of the present invention, after the winding module 100 winds the first section of the cotton pads on the reel, first, the cutting module 200 cuts the connection between the first section and the second section of the cotton pads, and then, the adjustment module 300 drives the reel to continue to rotate a certain angle along the winding direction of the first section so that the active end of the first section is completely wound on the material roll, and then the adhesion module 400 adheres and fixes the active end of the first section on the material roll so that the active end of the material roll on the reel can be fixed on the material roll, thereby reducing the probability that the cotton pads wound on the reel automatically unwind.

[0070] In some embodiments of the present invention, the adjustment module 300 includes a clamping assembly 310, the clamping assembly 310 includes a first driver 311, a second driver 312, a first jaw 313, and a second jaw 314. A clamping area for clamping the reel is formed between the first jaw 313 and the second jaw 314. The first jaw 313 includes a clamping frame 313a and a driving roller 313b. The driving roller 313b is rotatably arranged on the clamping frame 313a. The first driver 311 is connected to the clamping frame 313a and is used for driving the driving roller 313b to approach or depart from the clamping area. The second driver 312 is drivingly connected to the driving roller 313b, and the second driver 312 can drive the driving roller 313b to rotate to drive the reel in the clamping area to rotate.

[0071] For example, as Figure 5As shown, the clamping assembly 310 includes a first driver 311, a second driver 312, a first jaw 313, and a second jaw 314. The first jaw 313 is located above the second jaw 314, and a clamping area is formed between the first jaw 313 and the second jaw 314. The first jaw 313 includes a clamping frame 313a and two driving rollers 313b. The two driving rollers 313b both extend in the left-right direction and are distributed in the front-back direction. The two driving rollers 313b are rotatably arranged on the clamping frame 313a. The first driver 311 is respectively connected to the first jaw 313 and the second jaw 314 and is used to drive the first jaw 313 and the second jaw 314 to approach or move away from the clamping area synchronously. The second driver 312 is drivingly connected to the driving rollers 313b and is used to drive the driving rollers 313b to rotate.

[0072] It can be understood that the first driver 311 can drive the first jaw 313 and the second jaw 314 to approach each other to clamp the reel in the clamping area. At this time, the driving rollers 313b can abut against the material roll wound on the reel. Under the drive of the second driver 312, the material roll and the reel can rotate synchronously so that the movable end of the first section can be completely wound and attached to the material roll.

[0073] In a further embodiment of the present invention, referring to Figure 5 , the second driver 312 includes a motor 312a and a first transmission belt 312b. The motor 312a is drivingly connected to the driving roller 313b located at the rear through the first transmission belt 312b. The first jaw 313 further includes a second transmission belt 313c. The two driving rollers 313b are drivingly connected through the second transmission belt 313c.

[0074] Furthermore, under the drive of the motor 312a, the first transmission belt 312b can drive the driving roller 313b located at the rear to rotate, and the driving roller 313b located at the rear can synchronously drive the driving roller 313b located at the front to rotate through the second transmission belt 313c, thereby realizing the synchronous rotation of the two driving rollers 313b.

[0075] In some embodiments of the present invention, referring to Figure 5 , the adjustment module 300 further includes a driving assembly 320. The driving assembly 320 is connected to the clamping assembly 310. Under the drive of the driving assembly 320, the clamping assembly 310 can clamp the reel in the winding module 100 through the first jaw 313 and the second jaw 314 and move in a direction away from the second section to tension the junction of the first section and the second section.

[0076] It can be understood that after the reel in the winding module 100 finishes winding the cotton pads, the driving assembly 320 can drive the clamping assembly 310 to move forward, so that the reel can be located in the clamping area between the first jaw 313 and the second jaw 314. Then, the first driver 311 drives the first jaw 313 and the second jaw 314 to approach each other to clamp the reel. The driving assembly 320 drives the clamping assembly 310 to move backward to drive the reel away from the winding module 100, and at the same time, the junction of the first section and the second section is tensioned. Then, the cutting module 200 cuts the junction of the first section and the second section. Next, the second driver 312 drives the driving roller 313b to rotate, and the driving roller 313b drives the reel and the material roll to rotate a certain angle, so that the movable end of the first section is completely wound on the material roll.

[0077] In a further embodiment of the present invention, referring to Figure 5 , the driving assembly 320 includes a fifth driver 321, a slide rail 322 and a slide block 323. The slide rail 322 extends in the front-rear direction, and the slide block 323 is slidably disposed on the slide rail 322 in the front-rear direction. The driving end of the fifth driver 321 is connected to the slide block 323 and is used to drive the slide block 323 to slide along the slide rail 322. The clamping assembly 310 is disposed on the slide block 323.

[0078] Furthermore, driven by the fifth driver 321, the slide block 323 can drive the clamping assembly 310 to slide back and forth along the slide rail 322.

[0079] In a further embodiment of the present invention, referring to Figure 4 , the blanking device further includes a blanking track 500, and the blanking track 500 is located below the adjustment module 300. When the driving assembly 320 drives the clamping assembly 310 to move backward for a certain distance, the clamping assembly 310 is just located directly above the blanking track 500. At this time, after the first driver 311 drives the first jaw 313 and the second jaw 314 to move away from each other, the reel in the clamping area can just fall into the blanking track 500 to achieve the blanking of the reel.

[0080] In some embodiments of the present invention, the cutting module 200 includes a mounting frame 210, an upper cutting assembly 220, and a lower cutting assembly 230. The upper cutting assembly 220 includes a third driver 221, a first pressing member 222, a cutting knife 223, and an elastic connecting member. The first pressing member 222 includes a first pressing portion 222a and a second pressing portion 222b distributed horizontally. The cutting knife 223 is disposed between the first pressing portion 222a and the second pressing portion 222b. Both the first pressing member 222 and the cutting knife 223 are slidably disposed on the mounting frame 210 in the vertical direction, and are connected by an elastic connecting member between the first pressing member 222 and the cutting knife 223. The third driver 221 is connected to the cutting knife 223 and is used to drive the cutting knife 223 to perform a lifting motion. The lower cutting assembly 230 is used to cooperate with the first pressing portion 222a and the second pressing portion 222b to respectively press the first section and the second section.

[0081] For example, as Figure 6 and Figure 7 shown, the cutting module 200 includes a mounting frame 210, an upper cutting assembly 220, and a lower cutting assembly 230. The upper cutting assembly 220 includes a third driver 221, a first pressing member 222, a cutting knife 223, and an elastic connecting member. The first pressing member 222 includes a first pressing portion 222a and a second pressing portion 222b distributed front and back. The cutting knife 223 is disposed between the first pressing portion 222a and the second pressing portion 222b. Both the first pressing member 222 and the cutting knife 223 are slidably disposed on the mounting frame 210 in the vertical direction, and are connected by an elastic connecting member between the first pressing member 222 and the cutting knife 223. The third driver 221 is disposed on the mounting frame 210 and is connected to the cutting knife 223. The lower cutting assembly 230 is disposed below the upper cutting assembly 220.

[0082] It can be understood that, under the drive of the third driver 221, the first pressing member 222 and the cutting knife 223 move downward synchronously and close to each other, so that the first pressing portion 222a cooperates with the lower cutting assembly 230 to press the second section, and the second pressing portion 222b cooperates with the lower cutting assembly 230 to press the first section. Under the continuous drive of the third driver 221, the elastic connecting member is compressed, and the cutting knife 223 continues to move downward to squeeze the junction of the first section and the second section to cut off the connection between the first section and the second section.

[0083] In a further embodiment of the present invention, referring to Figure 6, the lower cutting assembly 230 includes a sixth driver 231 and a second pressing member 232. The second pressing member 232 is slidably disposed on the mounting bracket 210 in the vertical direction. The second pressing member 232 includes a third pressing portion 232a and a fourth pressing portion 232b distributed front and rear. The third pressing portion 232a is directly below the first pressing portion 222a, and the fourth pressing portion 232b is directly below the second pressing portion 222b. The sixth driver 231 is connected to the second pressing member 232 and is used to drive the second pressing member 232 to move in the vertical direction.

[0084] Furthermore, driven by the third driver 221, the first pressing member 222 moves downward. Driven by the sixth driver 231, the second pressing member 232 moves upward. The first pressing portion 222a and the third pressing portion 232a cooperate to clamp the second segment, and the second pressing portion 222b and the fourth pressing portion 232b cooperate to clamp the first segment.

[0085] In some embodiments of the present invention, referring to Figure 8 , the pasting module 400 includes a label supply component 410 and a labeling component 420. The label supply component 410 is used to supply labels. The labeling component 420 includes a fourth driver 421 and a suction head 422. The fourth driver 421 is connected to the suction head 422. Driven by the fourth driver 421, the suction head 422 can adsorb the labels supplied by the label supply component 410 and drive the labels to adhere and fix the movable end of the first segment on the coil.

[0086] It can be understood that after the label supply component 410 provides the labels, driven by the fourth driver 421, the suction head 422 can adsorb the labels provided by the label supply component 410. Then, the suction head 422 approaches the reel adjusted by the adjustment module 300, and transfers the movable end of the first segment to the coil on the reel through the labels.

[0087] In a further embodiment of the present invention, referring to Figure 8 and Figure 9 , the label supply component 410 includes a conveying roller group 411, a peeling knife 412, and a blowing head 413. The peeling knife 412 includes a first surface 412a and a second surface 412b with a certain included angle. The blowing head 413 is disposed on the front side of the peeling knife 412.

[0088] It can be understood that the conveying roller group 411 conveys the base film with labels pasted thereon to the first surface 412a. The base film moves along the first surface 412a and the second surface 412b in sequence. During the process of the base film moving from the first surface 412a to the second surface 412b, the labels on the base film fall off from the base film. During this process, the blowing head 413 blows air upward to support the labels separated from the base film until the labels move forward and are adsorbed on the lower end surface of the suction head 422.

[0089] Subsequently, driven by the fourth driver 421, the suction head 422 drives the label to move downward to attach the label to the material roll of the web.

[0090] The cotton pad production line according to the embodiment of the third aspect of the present invention includes the blanking device according to the embodiment of the second aspect of the present invention.
