[0016] A slitting method for a high-speed label automatic slitting machine comprises the following steps:

[0017] Step 1: Put a reel that matches the horizontal size of the label after slitting on the reel rod, and stick an adhesive strip on the reel. The reel rod located below the pressure-bonding strip plate is driven by the slave motor to reel the label. After reeling to a certain thickness, the main motor drives the rotating disk to rotate 180 degrees, automatically switching the positions of the two reel rods. During the switching, the label and the adhesive strip on the reel are automatically bonded and positioned by the positioning pressure-bonding component, and the label between the two reel rods is automatically separated by the energy-free segmenting component.

[0018] Step 2: Go to the reel rod at the corresponding position of the mounting shell and turn the cut end of the label to the corresponding through hole. Pull the rotating push plate in the middle position downward by hand. The rotating push plate drives other rotating push plates through the connecting piece, thereby driving the rotating handle to rotate. The rotating handle drives the multi-claw disk and the tape-receiving roller to rotate 90 degrees through the contact between the spring limit head and the arc-shaped limit plate to pull the adhesive tape, and fix the position of the multi-claw disk through the limit plate, so that an unused adhesive strip corresponds to the through hole.

[0019] Step 3: The rotating handle is attached to the last stop bar, and the rotating push plate is rotated to deflect the lower edge toward the position of the mounting shell. The single-rod arc push plate is pushed through the fixing plate to push the adhesive strip of the corresponding through hole toward the edge of the corresponding label opening at this time. The adhesive strip sticks to the edge of the label opening to prevent it from spreading. The rotating push plate is lifted up to the original position. At this time, the spring limit head, the rotating handle and the single-rod arc push plate are all back to their original positions and wait for the next use.

[0020] Step 4: According to the number and size of label slitting, choose to install the corresponding number of push-sealing parts at the corresponding middle position of each winding drum, and use the bolts in the bolt sliding block to install the push-sealing parts on the screw holes at different positions on the multi-screw hole support strip, so as to change the position and number of the push-sealing parts. The coordinated use can improve the flexibility of the synchronous sealing assembly; Step 5: After the push-sealing parts are installed, pull the screw hole rotary joints in the middle of two adjacent push-sealing parts to drive the sliding rod and the sliding cylinder to slide relative to each other until the screw hole rotary joints are correspondingly stuck under the connecting head, and use the screw rod to connect the two together. Later, one of the rotating push plates can be used to drive the other rotating push plates to perform the same movement.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. After the reel rod located below the pressure-bonding strip is driven by the slave motor to reel the label to a certain thickness, the main motor drives the rotating disk to rotate 180 degrees, automatically changing the positions of the two reel rods, and automatically positioning the label and the adhesive strip on the reel by pressing and bonding through the positioning pressure-bonding piece during the change of position. At the same time, under the limit of the triangular head, the angle plate is deflected and quickly reset under the action of the third spring, so that the cutting blade automatically separates the labels between the two reel rods. This method replaces manual operation without interrupting the work of the slitting machine. The working efficiency of the slitting machine is high, the manual labor is reduced, and the energy consumption of the slitting machine will not be increased.

[0023] 2. Hold the rotating push plate in the middle position and pull it downward. The rotating push plate drives other rotating push plates to move together through the connecting piece. The rotating handle bar will drive the multi-claw disk to rotate 90 degrees through the abutment of the spring limit head and the arc-shaped limit plate. The multi-claw disk drives the take-up roller to pull the adhesive tape to an adhesive strip corresponding to the through hole. After the rotating handle bar is limited by the last stop bar, the rotating push plate is rotated to push the single-rod arc-shaped push plate through the fixed plate to push the adhesive strip corresponding to the through hole to the corresponding label opening edge at this time to seal it. All the openings of the labels that have been slit and rolled up can be sealed by one press. There is no need to seal them one by one, wasting time and physical effort, thereby reducing labor.

[0033] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0034] The present invention provides a technical solution: a high-speed automatic label cutting machine, such as Figure 1-4As shown, it includes an equipment frame 1, a self-changing cutting component 4 and a synchronous sealing component 5. A support frame 2 is fixed on one side above the equipment frame 1. Vertical slots 3 are provided on one side of the equipment frame 1 and the support frame 2. A control box is arranged above the equipment frame 1. A rotating disk 6 is rotated on one side of the equipment frame 1. Two winding rods 7 are rotated on one side of the rotating disk 6. The two winding rods 7 are equidistantly distributed and are used to rewind the slit labels. A main motor 8 and two slave motors 9 are arranged on the other side of the rotating disk 6. One end of the output shaft of the main motor 8 is fixed to one side of the rotating disk 6. The main motor 8 and the two slave motors 9 are connected through the existing technology and the control switch in the control box. One end of the output shaft of the two slave motors 9 is respectively fixed to one end of the two winding rods 7. When the two winding rods 7 are changed in position, the PLC controller in the control box controls the main motor 8 to start, and the main motor 8 rotates 180 degrees to interchange the positions of the two winding rods 7. As for the main motor When the machine 8 is started, a starting time interval can be set. The positions of the two winding rods 7 are interchanged at regular intervals so that the thickness of the labels wound on the two winding rods 7 is similar. When the main motor 8 is started, the slave motor 9 connected to the winding rod 7 with the labels wound on it slows down, and the labels cut in sections are wound on the winding rod 7. The winding rod 7 with no labels wound on it will be sent to the position below the pressing and gluing strip 49, and the winding rod 7 with the labels wound on it will be sent to the corresponding position on the back of the mounting shell 51. An adjustable slitting mechanism 10 and a unwinding rod 11 are provided on one side of the equipment frame 1. The spacing of the slitting knives in the adjustable slitting mechanism 10 is adjustable. The labels placed on the unwinding rod 11 pass through each guide roller, pass through the adjustable slitting mechanism 10, and one end is adhered to the winding drum arranged outside the winding rod 7. The slave motor 9 corresponding to the winding rod 7 can be started to wind up the labels. When the labels are wound up, they are cut into required sizes by the slitting of the adjustable slitting mechanism 10.

[0035] like Figure 1-4As shown, the self-changing cutting component 4 is arranged between the equipment frame 1 and the support frame 2. The self-changing cutting component 4 automatically aligns the label, rewinds and cuts it when the label is changed. There is no need to manually change the position of the two rewinding rods 7 and then cut the label between the two rewinding rods 7, and press the label to stick it on the rewinding drum arranged outside the rewinding rod 7. These works can automatically realize energy-free cutting and segmentation when the two rewinding rods 7 change positions and rewind. There is no need to stop the slitting machine when performing the above working steps, thereby improving the working efficiency of the slitting machine. The self-changing cutting component 4 includes a positioning pressing and bonding part, a positioning pressing and bonding part, a positioning pressing and bonding part, and a positioning pressing and bonding part. The pressure-bonded part includes a gravity bar 41, the two ends of which slide inside the two vertical grooves 3 respectively, a plurality of fixed cylinders 42 are fixed below the gravity bar 41, a first spring 43 is fixed inside the plurality of fixed cylinders 42, a connecting rod 44 slides inside the plurality of fixed cylinders 42, one end of the first spring 43 is fixed to the upper end of the connecting rod 44, when the first spring 43 is at its original length, only one end of the connecting rod 44 connected to the first spring 43 is in the fixed cylinder 42, and the rest of the rod body is below the fixed cylinder 42, a hollow bar 44 is fixed between one end of the plurality of connecting rods 44 5. A sliding plate 46 slides inside the hollow bar 45, and a plurality of second springs 47 are fixed above the sliding plate 46. One end of the second spring 47 is fixed to the top of the inner wall of the hollow bar 45. A plurality of guide rods 48 are fixed below the sliding plate 46. One end of each of the plurality of guide rods 48 extends to the bottom of the hollow bar 45. A pressing and bonding strip plate 49 is fixed between one end of the plurality of guide rods 48. The lower edge of the pressing and bonding strip plate 49 is set in an arc shape, and the curvature of the bottom is in contact with the outer surface of the winding drum sleeved on the winding rod 7. When the gravity bar 41 falls, it is limited by the second spring 47. Before the gravity bar 41 falls to the bottom of the vertical groove 3, the pressing and gluing strip 49 will first press on the outer surface of the winding drum, thereby pressing the label so that it sticks to the adhesive strip that has been glued to the outside of the winding drum in advance and fixes it, making it convenient for the winding rod 7 to wind up the label. When the gravity bar 41 continues to fall to the bottom of the vertical groove 3 in the later stage, the pressing and gluing strip 49 will push the guide rod 48 and the sliding plate 46 to slide upward and squeeze the second spring 47. When the winding rod 7 rotates in the later stage, the thickness of the label wound on the outside of the winding drum gradually increases, thereby pushing the pressing and gluing strip 49 upward, and the pressing and gluing strip 49 is always pressed above the rolled label.

[0036] like Figure 1-4As shown, the self-changing cutting component 4 also includes an energy-free segmenting member, which is arranged on the front of the hollow strip 45. The energy-free segmenting member is used to automatically segment the label. The energy-free segmenting member includes a hollow shell 410 and two triangular head bar rods 411. The hollow shell 410 is fixed to the front of the hollow strip 45. One end of the two triangular head bar rods 411 is respectively fixed to one side of the equipment frame 1 and the support frame 2, and the triangular head end of the triangular head bar rod 411 is at the bottom. The interior of the hollow shell 410 is slidably provided with a cutting blade 4 12, a transverse groove is provided below the hollow shell 410, and the cutting blade 412 passes through the hollow shell 410 through the transverse groove, and a plurality of third springs 413 are fixed above the cutting blade 412, and one end of the third spring 413 is fixed above the inner wall of the hollow shell 410, and both sides above the cutting blade 412 are provided with a slide groove 414, and a slider 415 is slidably provided inside the two slide grooves 414, and a folded angle plate 416 is rotated above the two sliders 415, and when the third spring 413 is at the original length, the cutting blade 4 12 is inside the hollow shell 410 to prevent the sharp edge of the cutting blade 412 from being outside the hollow shell 410 and cutting the label. Through slots 417 are provided on both sides of the hollow shell 410. The corners of the two angled plates 416 are rotated inside the hollow shell 410. The two angled plates 416 are respectively inserted into the two through slots 417. When the pressing and bonding strip 49 is just pressed on the winding drum, the end of the angled plate 416 outside the hollow shell 410 just contacts the upper side of the triangular head and is pressed on the gravity strip 4 When the label 410 continues to slide downward, driven by the hollow bar 45, the hollow shell 410 and the angle plate 416 continue to move downward, and one end of the angle plate 416 is deflected upward by the limit of the triangular head, so that the other end pushes the cutting blade 412 out of the hollow shell 410 through the slider 415 to segment the label between the two winding rods 7, and when the gravity bar 41 falls to the bottom of the vertical groove 3, one end of the angle plate 416 moves to the bottom of the triangular head, and drives the cutting blade 412 to return to its original position under the reset of the third spring 413.

[0037] A take-up drum that matches the lateral size of the label after slitting is put on the take-up rod 7, and an adhesive strip is attached to the take-up drum, so that one end of the label can be glued to the take-up drum and fixed. A take-up rod 7 located below the pressure-bonding strip plate 49 is driven by a slave motor 9 connected to it, and the take-up drum outside it reels the label slit by the adjustable slitting mechanism 10. When rewinding, as the thickness of the label gradually increases, the pressure-bonding strip plate 49 will be pushed upward, and the pressure-bonding strip plate 49 will push the hollow strip 45 upward, so as to push the connecting rod 44 into the fixed tube 42 to squeeze the first spring 43, and in the process of the hollow strip 45 driving the hollow shell 410 to move upward, one end of the angle plate 416 will be on the triangular head strip Under the limit of the triangular head of the rod 411, it deflects downward, so that the other end will move upward and drive the cutting blade 412 upward through the slider 415 until the angle plate 416 moves above the triangular head. Under the reset of the third spring 413, the cutting blade 412 returns to its original position until it is wound for a certain period of time. After a certain thickness is wound on the winding drum, the main motor 8 drives the rotating disk 6 to rotate 180 degrees, and the winding rod 7 under the pressing and bonding strip plate 49 is turned from the top to the position of the mounting shell 51. When the winding rod 7 rotates, the self-changing cutting assembly 4 will be moved upward as a whole through the pressing and bonding strip plate 49, and the gravity bar 41 will move vertically upward under the guidance of the vertical groove 3 until the winding is completed. The rod 7 is staggered to the position below the pressure-bonding strip 49, and the gravity strip 41 falls downward. Limited by the second spring 47, the pressure-bonding strip 49 will first press on the outer surface of the winding drum before the gravity strip 41 falls to the bottom of the vertical groove 3, so as to press the label to make it stick to the adhesive strip that has been pre-pasted on the outside of the winding drum and fix it, making it convenient for the winding rod 7 to roll up the label. When the pressure-bonding strip 49 is just pressed on the winding drum, one end of the angle plate 416 outside the hollow shell 410 just touches the upper side of the triangular head, and when the gravity strip 41 continues to slide down, the angle plate 416 continues to move downward under the drive of the hollow strip 45, and one end of the angle plate 416 is deflected upward by the limit of the triangular head, so as to The other end uses the slider 415 to push the cutting blade 412 out of the hollow shell 410 to cut the label between the two winding rods 7 in sections, and when the gravity bar 41 falls to the bottom of the vertical groove 3, one end of the angle plate 416 will move to the bottom of the triangular head, and the cutting blade 412 will be driven to return to its original position under the reset of the third spring 413. At this time, the label cut by the winding rod below the pressing and bonding strip 49, the other winding rod 7 will rotate from the bottom to the bottom of the pressing and bonding strip 49, and the winding rod 7 will continue to rewind the label by the slave motor 9 connected to it, without interrupting the operation of the slitting machine, the working efficiency of the slitting machine is high, the labor workload is reduced, and the energy consumption of the slitting machine will not be increased.

The synchronous sealing assembly 5 is used to uniformly seal the rolls of labels that are slit and rewound. The synchronous sealing assembly 5 includes a plurality of sealing pushers. The number of sealing pushers corresponds to the number of sections into which the labels are transversely slit. The sealing pushers include a mounting shell 51. An arc is arranged in the middle of the back of the mounting shell 51. A through hole is opened at the arc setting position. A tape unwinding roller 52 and a tape rewinding roller 53 are rotated inside the mounting shell 51. A U-shaped arc is fixed inside the mounting shell 51. shaped limiting plate 54, the U-shaped arc limiting plate 54 is close to the through hole, and an adhesive tape 55 is wrapped around the outside of the tape unwinding roller 52. The adhesive tape 55 is provided with a sticky adhesive strip that can be torn off at the corresponding through hole, and "punch lines" similar to the connection of a roll of toilet paper are provided around the adhesive strip to facilitate separation from the adhesive tape 55 later. The adhesive strip is located in the middle position on the adhesive tape 55 and is arranged one by one. One end of the adhesive tape 55 passes through the inner side of the U-shaped arc limiting plate 54 and is wrapped around the outside of the tape taking-up roller 53.

[0039] like Figure 5-7 As shown, one end of the take-up roller 53 is fixed with a multi-claw disc 56. Figure 7As shown, the multi-claw disk 56 is composed of a disk and four claws equidistantly distributed around the disk. The four claws have a certain curvature, one side is a convex curved surface, and the other side is a concave surface. The internal rotation of the mounting shell 51 is limited by a dial plate 57, and an inner spring 58 is fixed below the limit dial plate 57. When the inner spring 58 is at its original length, the limit dial plate 57 is in the concave surface of a claw, thereby limiting the position of the multi-claw disk 56. At this time, there is a connecting piece fixed to the inside of the mounting shell 51 above the limit dial plate 57, and the connecting piece limits the position of the limit dial plate 57 To prevent it from being deflected upward under force, a plurality of arc-shaped limit pieces 59 are fixed on one side of the multi-claw disk 56. There are four arc-shaped limit pieces 59, which are equidistant from each other. Like the four claws, the angle between adjacent claws is ninety degrees. A rotating handle 510 is rotatably arranged on one side of the multi-claw disk 56. The rotating handle 510 is located outside the mounting shell 51. A spring limit head 511 is arranged on one side of the rotating handle 510. The spring limit head 511 is located inside the mounting shell 51 and corresponds to the position of the arc-shaped limit piece 59. The spring limit head 511 is composed of a hollow protrusion, which is fixed The small spring fixed in the hollow protrusion and the protrusion sliding inside the hollow protrusion are combined. When the small spring is at its original length, the protrusion is completely outside the hollow protrusion. At this time, the protrusion is in the gap between the head and the tail of the two arc-shaped limit pieces 59. One end of the rotating handle 510 is rotated with a rotating push plate 512, and one side of the mounting shell 51 is fixed with a starting stop bar 513 and an end stop bar 514. When the rotating handle 510 and the starting stop bar 513 are fitted, the rotating handle 510 can be rotated later to drive the multi-claw disk 56 to rotate ninety degrees through an arc-shaped limit piece 59 until the rotation The movable handle bar 510 is fitted on the final stop bar 514, which is the path for the rotating handle bar 510 to rotate ninety degrees. At this time, the limit dial plate 57 will be stuck in one of the corresponding claws on the multi-claw disk 56, and a single-rod arc-shaped push plate 515 is slid inside the mounting shell 51. A return spring 516 is sleeved on the outside of the single-rod arc-shaped push plate 515, and one end of the return spring 516 is fixed to the inside of the mounting shell 51, and one end of the single-rod arc-shaped push plate 515 extends to the outside of the mounting shell 51. A fixing plate is fixed to one end of the single-rod arc-shaped push plate 515 extending to the outside of the mounting shell 51.

[0040] The motor 9 on the take-up rod 7 rotates to the corresponding position of the mounting shell 51 and slowly rotates until the end of the label to be cut corresponds to the through hole. At this time, the rotating push plate 512 in the middle position is held and pulled downward. The rotating push plate 512 drives other rotating push plates 512 through the connecting piece, and the rotating push plate 512 drives the rotating handle bar 510 to rotate. The rotating handle bar 510 will drive the multi-claw plate 56 to rotate ninety degrees through the abutment of the spring limit head 511 and the arc limit plate 59, and the multi-claw plate 56 will drive the take-up roller 53 to reel up a part of the adhesive tape 55 on its outside. At this time, the adhesive tape 55 on the unwinding roller 52 will release a part. At this time, an adhesive strip will move to the through hole correspondingly. When the multi-claw plate 56 rotates ninety degrees, the limit dial plate 57 will be stuck in the concave surface of the next claw tooth, fixing the position of the multi-claw plate 56. At this time, the rotating handle bar 510 will be attached to the last stop bar 514 and will not continue to move downward, and will not drive the multi-claw plate 56 to continue to rotate. The push plate 512 is then rotated and the lower edge of the push plate 512 is deflected toward the position of the mounting shell 51, and the single-rod arc push plate 515 is pushed by the fixing piece to move, and the single-rod arc push plate 515 pushes the adhesive strip of the corresponding through hole to the edge of the label opening corresponding to the label opening at this time, and the adhesive strip sticks to the edge of the label opening to prevent it from spreading. After pressing, the push plate 512 is lifted upward, and the rotating handle bar 510 drives the spring limit head 511 to rotate ninety degrees and get stuck between the head and tail ends of the two arc limit plates 59, and the multi-claw disc 56 will not be reversed under the blocking position of the limit dial plate 57. At this time, the rotating handle bar 510 is stuck on the starting stop bar 513, waiting for the next use. At this time, the single-rod arc push plate 515 returns to its original position under the reset of the reset spring 516 and waits for the next use. By pressing once, all the openings of the labels that have been cut and rolled up are sealed, and there is no need to seal them one by one to waste time and physical strength, reducing the workload.

[0041] like Figure 1-7As shown, the synchronous sealing assembly 5 also includes a plurality of connecting members, which are arranged on both sides of the rotating push plate 512, and are used to connect two adjacent pushing and sealing members. The connecting members include a sliding cylinder 517 that slides inside the rotating push plate 512 and a connecting head 518 that is fixed to one side of the rotating push plate 512. Two or more sliding cylinders 517 can also be provided, which are slidably mounted on each other. The specific size and number are set according to the rotating push plate 512. The internal thread of the connecting head 518 is connected with a screw rod 519, and a sliding rod 520 slides inside the sliding cylinder 517. A screw hole rotary joint 521 is fixed to one end of the sliding rod 520. The screw hole rotary joints 521 and the connecting head 518 on two adjacent rotating push plates 512 are stacked up and down and engaged, and the screw 519 is screwed into the screw hole of the screw hole rotary joint 521 The synchronous sealing assembly 5 also includes a positioning member, which is arranged on one side of the equipment frame 1 and is used to change the positions of multiple sealing members. The positioning member includes a multi-screw hole support strip 522 fixed to one side of the equipment frame 1 and a bolt sliding block 523 sliding on the outside of the multi-screw hole support strip 522. The bolt sliding block 523 is fixed to the bottom of the mounting shell 51. A screw hole positioning strip 524 is fixed below the multi-screw hole support strip 522. Bolts are threadedly connected in the bolt sliding block 523. The screw hole positioning strip 524 is provided with a screw hole alignment groove. An alignment strip corresponding to the bolt position above and below is provided below the bolt sliding block 523. When the alignment strip corresponds to the screw hole alignment groove on the screw hole positioning strip 524, the bolt corresponds to a screw hole on the multi-screw hole support strip 522, which helps to quickly align the bolt and the screw hole.

[0042] The locking member 520 and the locking member 521 are used to lock the locking member 520 and the locking member 522.

[0043] A slitting method for a high-speed label automatic slitting machine comprises the following steps:

[0044] Step 1: Put a reel that matches the transverse size of the label after slitting on the reel rod 7, and stick an adhesive strip on the reel. The reel rod 7 located below the pressure-bonding strip plate 49 is driven by the slave motor 9 to reel the label. After reeling to a certain thickness, the main motor 8 drives the rotating disk 6 to rotate 180 degrees, automatically switching the positions of the two reel rods 7. During the switching, the label and the adhesive strip on the reel are automatically bonded and positioned by the positioning pressure-bonding component, and the label between the two reel rods 7 is automatically separated by the energy-free segmenting component.

[0045] Step 2: Go to the reeling rod 7 at the corresponding position of the mounting shell 51 and turn the cut end of the label to the corresponding through hole. Pull down the rotating push plate 512 in the middle position by hand. The rotating push plate 512 drives other rotating push plates 512 through the connecting piece, thereby driving the rotating handle 510 to rotate. The rotating handle 510 drives the multi-claw disk 56 and the tape-receiving roller 53 to rotate ninety degrees through the contact between the spring limit head 511 and the arc-shaped limit sheet 59 to pull the adhesive tape 55, and fix the position of the multi-claw disk 56 through the limit dial plate 57, so that an unused adhesive strip corresponds to the through hole.

[0046] Step 3: Rotate the handle 510 to stick it on the last stop bar 514, rotate the rotating push plate 512 to make its lower edge deflect toward the position of the mounting shell 51, push the single-rod arc push plate 515 through the fixing piece to push the adhesive strip of the corresponding through hole toward the edge of the corresponding label opening at this time, and the adhesive strip sticks to the edge of the label opening to prevent it from spreading, and lift the rotating push plate 512 upward to the original position, at this time the spring limit head 511, the rotating handle 510 and the single-rod arc push plate 515 all return to their original positions and wait for the next use;

[0047] Step 4: According to the number and size of the labels cut, i.e. the position and number of the winding drums, a corresponding number of sealing pushers are selected and installed at the corresponding middle position of each winding drum, and the sealing pushers are installed on the screw holes at different positions on the multi-screw hole support bar 522 by using the bolts in the bolt sliding block 523, so as to change the position and number of the sealing pushers, and the flexibility of the synchronous sealing assembly 5 can be improved by using them together;

[0048] Step 5: After the push-sealing parts are installed, pull the screw hole rotary joint 521 between the two adjacent push-sealing parts to drive the sliding rod 520 and the sliding cylinder 517 to slide relative to each other until the screw hole rotary joint 521 is correspondingly stuck under the connecting head 518, and use the screw 519 to connect the two together. Later, one of the rotating push plates 512 can be used to drive the other rotating push plates 512 to perform the same movement.
