Description

Technical Field

[0001] The invention relates to the field of clothing production equipment, in particular to an automatic label folding and pasting device. Background Art

[0002] During the fabric manufacturing process, labels are usually sewn on the inside of the fabric to serve as identification. When sewing the labels, a single label is usually cut from a whole roll of labels, and then the label is folded in half and sewn onto the textile product.

[0003] Related technologies can refer to the Chinese patent with announcement number CN211446151U, which discloses a label folding device, including a support plate, a label pressing mechanism and a label folding mechanism; at least one through hole is set on the support plate; the label pressing mechanism includes a pressure rod and a first driving mechanism for driving the pressure rod to rise and fall; the pressure rod is located above the support plate; a through hole is set on the pressure rod; the label folding mechanism includes a plug plate and a second driving mechanism for driving the plug plate to rise and fall; the plug plate can pass through the through hole and the through hole. The device has a simple structure and is easy to use. It can automatically fold the label, save time and effort, and has good folding quality. The plug rod can also provide support for the label, which is convenient for subsequent clamping and placement of the label, improves work efficiency, and is convenient for mass production.

[0004] Regarding the above-mentioned related technologies, the material of the label is different depending on the different fabric usage environments. For labels on sportswear or outdoor products, they are usually required to have high strength and wear resistance. Therefore, this type of label mostly uses nylon as the raw material. In addition to high strength and wear resistance, nylon is also elastic. After such labels are folded in half by the above-mentioned folding mechanism, if they are not further pressed and fixed, the folded labels are easily reset due to their own elasticity. When storing the folded labels in batches, an additional pressing device is required, which makes it inconvenient to fold the labels in half. Summary of the invention

[0007] By adopting the above technical solution, when the label roll is placed on the unwinding roller, the label is driven by the feeding roller to pass through the feed port, the clamping plate is initially located away from the positioning plate, and the clamping plate and the positioning plate are arranged vertically, one end of the label passes between the clamping plate and the positioning plate, at this time, the rack is operated to move downward, so that the rack drives the positioning plate and the clamping plate to rotate through the gear, and the positioning plate and the clamping plate cooperate to drive the end of the label to flip, and the flipped clamping plate is directly opposite to the resistance block, the resistance block is operated to approach the clamping plate, and the clamping plate is pushed close to the positioning plate, so that the clamping plate and the positioning plate disc cooperate with the end of the label to clamp, and the elastic member is deformed. The feeding roller continues to convey the label, and the label is bent in a state where the end is restricted. When the bent label reaches the required length, the cutting knife is driven downward under the action of the support frame, so that the cutting knife cuts the folded label. The folded label is transported to the top of the support plate by the feeding clamp, and the two ends of the label are heat-pressed by the heat pressing plate, thereby reducing the probability of the label being reset after being folded, making it easier to store the label and improving the convenience of folding the label.

[0008] Optionally, the feeding clamp comprises an upper clamp, a lower clamp, a transverse frame and a longitudinal frame. The frame is fixedly connected with a guide rail along the direction of the support frame pointing to the support plate, the guide rail is located on the same side of the support plate and the support frame, the longitudinal frame is slidably connected to the guide rail along the length direction of the guide rail, the guide rail is provided with a driving member 1 for driving the longitudinal frame to move, the transverse frame is slidably connected to the longitudinal frame along the width direction of the guide rail, the longitudinal frame is provided with a driving member 2 for driving the transverse movement, the upper clamp and the lower clamp are both located on the side of the transverse frame close to the support plate, and the upper clamp is located directly above the lower clamp, the transverse frame is provided with a clamp cylinder for driving the upper clamp and the lower clamp to move closer to or away from each other, and an avoidance groove adapted to the upper clamp and the lower clamp is opened on the upper end of the support plate, and the avoidance groove is located on the side of the hot pressing plate away from the support frame.

[0009] By adopting the above technical scheme, in the initial state, the transverse moving frame is located near the guide rail, and when the label is folded in half, the second driving member drives the transverse moving frame close to the label, so that the transverse moving frame drives the upper clamp and the lower clamp close to the label, and the label is located between the upper clamp and the lower clamp, and the upper clamp is driven close to the lower clamp by the clamp cylinder, so that the upper clamp and the lower clamp cooperate to clamp the label, and the longitudinal moving frame is driven to move along the guide rail by the first driving member, and then the label is driven to move above the support plate, so that the hot pressing plate can heat press the label. During hot pressing, the upper clamp and the lower clamp are located in the avoidance groove, thereby reducing the probability of collision between the hot pressing plate and the upper clamp.

[0010] Optionally, the frame is further provided with a re-pressure plate, which is located on the side of the hot pressing plate away from the support frame, and the re-pressure plate is located directly above the support plate.

[0013] By adopting the above technical solution, after completing the second folding of the label, the label is driven to move to the top of the extension block by the material picking claw. At this time, the grabbing plate is controlled to move downward, so that the grabbing plate drives the suction cup to contact the label. Under the action of the vacuum device, the grabbing plate adsorbs the label through the suction cup. After the suction cup adsorbs the label, the grabbing plate resets, and the material picking block moves horizontally, thereby driving the label to move above the material storage box, making it easy to place the label in the material storage box, which is beneficial to improving the convenience of placing the label.

[0014] Optionally, a limit plate is provided between the support frame and the discharge roller, the limit plate is perpendicular to the label conveying direction, a material feeding trough is provided at the lower end of the limit plate, two baffles parallel to each other are provided in the material feeding trough, and two through slots corresponding to the baffles are provided along the length direction of the limit plate, and the baffles are provided with abutment bolts, which pass through the through slots and are threadedly connected to the baffles, and the label passes between the two baffles and abuts against the baffles.

[0015] By adopting the above technical solution, the limit plate limits the vertical displacement of the baffle through the material feeding trough, and limits the lateral displacement of the baffle through the abutment bolt, so that the baffle is in a positioned state, and the baffle and the limit plate cooperate to limit the label, which is beneficial to improve the convenience of conveying labels.

[0016] Optionally, the frame is provided with a control center for controlling the operation of the feed roller, and a detection device is provided on the side of the limit plate close to the support frame. The label passes through the sensing area of ​​the detection device, and the detection device is electrically connected to the control system. When the detection device senses that the length of the label passing through the sensing area reaches a threshold, it is triggered and sends an electrical signal to the control center. After receiving the electrical signal, the control center controls the feed roller to stop.

[0017] By adopting the above technical solution, the detection device is used to monitor the conveying length of the label, thereby ensuring that the bending length of the label meets the standard. Under the action of the control center, the detection device and the feeding roller are linked to improve the cutting accuracy of the label.

[0018] Optionally, the feeding roller includes a positioning roller, a supporting roller and a driving roller, there are two positioning rollers, the two positioning rollers are parallel to each other and arranged vertically, the frame is provided with a fixed block for supporting the positioning roller, the fixed block is located on the side of the limit plate away from the supporting frame, the label passes between the two positioning rollers and extends toward the limit plate along the positioning roller located below, the driving roller is located on the side of the limit plate away from the positioning roller, the driving roller is rotatably connected to the supporting frame, the supporting roller is located below the driving roller and is rotatably connected to the frame, the frame is provided with a driving motor for driving the supporting roller to rotate, the label passes between the driving roller and the supporting roller and is rollingly connected to both, the outer side of the driving roller is coated with an anti-slip layer, and the anti-slip layer is in contact with the label.

[0019] By adopting the above technical solution, the positioning roller restricts the label under the support of the fixed block, and the label is kept in a tensioned state during the transportation process through friction. The driving motor drives the driving roller and the supporting roller to rotate to drive the label to move. The anti-skid layer is beneficial to improving the contact stability between the driving roller and the label and reducing the probability of relative slippage between the driving roller and the label.

[0020] Optionally, the storage box is vertically provided with a placement cavity for placing labels, a carrying plate is provided in the placement cavity, the carrying plate is vertically slidably connected to the storage box, an elastic member 2 is provided between the carrying plate and the storage box, the elastic member 2 applies an upward thrust to the carrying plate, and a pressure plate for sealing the placement cavity is provided at the upper end of the storage box.

[0021] By adopting the above technical solution, the placement cavity is used to place the label. After the label is placed in the placement cavity, the carrier plate cooperates with the pressure plate under the action of the second elastic member to clamp and position the label, and then further compresses and shapes the label.

[0022] Optionally, the pressure plate is vertically connected to the material storage box for rotation, a torsion spring is provided between the pressure plate and the material storage box, the torsion spring is used to drive the pressure plate to approach the load-bearing plate, the upper end of the pressure plate is hinged with a connecting rod, the end of the connecting rod away from the pressure plate is hinged with a moving block, the moving block is vertically connected to the material storage box for sliding, the material storage box is also vertically connected with an adjusting block for sliding, a connecting rod is provided between the adjusting block and the moving block, when the adjusting block moves, the moving block is driven to move in the opposite direction by the connecting rod, one end of the adjusting block passes through the material storage box and is located in the placement cavity, and the material taking plate is opposite to the adjusting block after entering the placement cavity.

[0023] By adopting the above technical scheme, in the initial state, both pressure plates are in a horizontal state under the action of the torsion spring. At this time, the adjusting block is located at the upper end of the material storage box. The grabbing plate drives the label to move toward the placement cavity and approaches the adjusting block, and pushes the adjusting block downward. When the adjusting block moves, it drives the moving block to move in the opposite direction through the linkage rod, so that the moving block drives the connecting rod to move upward. When the connecting rod moves, it drives the corresponding pressure plate to flip upward, and then avoids the grabbing plate, so that the grabbing plate drives the label to move under the pressure plate. At this time, the adsorption of the label is stopped, and the grabbing plate is driven to move up. Under the action of the torsion spring, the pressure plate drives the moving block and the adjusting block to reset, and the pressure plate presses the label tightly, thereby improving the placement stability of the label.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1.

The feed roller continues to convey the label, and the label is bent in a state where the end is restricted. When the bent label reaches the required length, the cutting knife is driven downward by the support frame, so that the cutting knife cuts the folded label. The folded label is conveyed to the top of the support plate by the feeding clamp, and the two ends of the label are heat-pressed by the heat pressing plate, thereby reducing the probability of the label being reset again after being folded, making it easier to store the label and improving the convenience of folding the label; 2.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses a device for automatically folding and pasting labels.

[0034] Example: Reference Figure 1 and Figure 2 A device for automatically folding and pasting labels comprises a frame 1, the upper end of which is rotatably connected to a feeding roller 11, and the feeding roller 11 is used to place a label roll. A support frame 3 is also fixed to the upper end of the frame 1, and the support frame 3 is arranged vertically, and a feeding port 31 is opened at the lower end of the support frame 3.

[0035] Reference Figure 2 and Figure 3 A limit plate 7 is also provided at the upper end of the frame 1, and a material feeding groove 71 is opened along the width direction on one side of the limit plate 7 close to the frame 1. Two baffles 72 are provided between the limit plate 7 and the frame 1, and both baffles 72 are located in the material feeding groove 71 and are slidably connected with the limit plate 7 along the length direction of the material feeding groove 71.

[0036] Reference Figure 2 and Figure 3The limiting plate 7 cooperates with the frame 1 to limit the displacement of the baffle 72 in the vertical direction. The baffle 72 is provided with two abutting bolts 74 corresponding to the baffle 72, and the baffle 72 is provided with a through slot 73 adapted to the abutting bolts 74 along the length direction. The abutting bolts 74 pass through the through slot 73 and are threadedly connected to the baffle 72. The limiting plate 7 cooperates with the abutting bolts 74 to limit the displacement of the baffle 72 in the lateral direction. When the position of the baffle 72 needs to be adjusted, the abutting bolts 74 are moved along the length direction of the through slot 73, thereby driving the baffle 72 to move.

[0037] Reference Figure 2 and Figure 3 A feeding roller 2 is provided between the unwinding roller 11 and the support frame 3. The feeding roller 2 includes two positioning rollers 21, a driving roller 23 and a supporting roller 22. Two fixing blocks 18 are fixed to the upper end of the frame 1. The two positioning rollers 21 are fixedly connected between the two fixing blocks 18. The two positioning rollers 21 are parallel to each other and distributed vertically. One end of the label roll is wound around two positioning rollers 21 in sequence and extends toward the support frame 3. After passing through the positioning rollers 21, the label passes between the two baffles 72. The baffles 72 cooperate with the limiting plate 7 to limit the label. The baffle 72 has a straight groove along the length direction. The side of the label is located in the straight groove, thereby improving the limiting effect of the baffle 72 on the label.

[0038] Reference Figure 2 and Figure 3 The support roller 22 is located at the lower end of the support frame 3. The frame 1 is provided with a groove for placing the support roller 22. The support roller 22 is located in the groove and is rotatably connected to the frame 1. The upper end of the support roller 22 is flush with the upper end of the frame 1. The frame 1 is provided with a driving motor 19. The output shaft of the driving motor 19 is connected to the support roller 22 to drive the support roller 22 to rotate. The outer circle of the support roller 22 is provided with a plurality of anti-skid grooves. The driving roller 23 is located at the lower end of the support frame 3 and is rotatably connected to the support frame 3. The driving roller 23 is located directly above the supporting roller 22. The end of the label passes through between the two baffles 72 and enters between the driving roller 23 and the supporting roller 22.

[0039] Reference Figure 2 and Figure 3 The driving roller 23 and the supporting roller 22 are in contact with the label and position the label, so that the supporting roller 22 drives the label to move when rotating, and then pulls the label, so that the label material is unwound under the support of the unwinding roller 11. The driving roller 23 is provided with an anti-skid layer 231 on the outside, which is conducive to improving the friction between the driving roller 23 and the label, thereby improving the connection stability between the driving roller 23 and the label. A detection device 75 is installed on the side of the limit plate 7 away from the positioning roller 21. The detection device 75 can be a visual sensor, a displacement sensor, etc., which is used to measure the conveying length of the label.

[0040] Reference Figure 2 and Figure 3 When the label passes between the two baffles 72, it passes through the detection range of the detection device 75. At this time, the detection device 75 detects the conveying length of the label. When the detection device 75 detects that the conveying length of the label reaches the threshold, it is triggered. The frame 1 is provided with a control center for controlling the operation of the drive motor 19. The control center is a prior art, so it is not described in detail here. The detection device 75 is electrically connected to the control center. After the detection device 75 is triggered, it sends an electrical signal to the control center. After receiving the electrical signal, the control center controls the drive motor 19 to stop running. When the support roller 22 and the drive roller 23 drive the label to move, the positioning roller 21 blocks the label through friction, so that the label is in a tensioned state, which is beneficial to improve the measurement accuracy of the detection device 75.

[0041] Reference Figure 1 and Figure 4 The support frame 3 is rotatably connected with gears 32 on both sides of the feed port 31. The label passes between the two gears 32 under the action of the feed roller 2. The support frame 3 is vertically slidably connected with a rack 33 meshing with the gear 32, and the support frame 3 is installed with a cylinder 331 for driving the rack 33 to move. When the rack 33 moves, it drives the gear 32 to rotate. A positioning plate 321 and a clamping plate 322 are arranged between the two gears 32. The positioning plate 321 and the clamping plate 322 are parallel to each other, and the positioning plate 321 and the clamping plate 322 are fixedly connected. The clamping plate 322 is slidably connected with the gear 32 in the direction of approaching or moving away from the positioning plate 321. When the gear 32 rotates, it drives the positioning plate 321 and the clamping plate 322 to move. An elastic member 323 is provided between the gear 32 and the clamping plate 322. The elastic member 323 is a spring. One end of the spring is fixedly connected to the gear 32, and the other end is fixedly connected to the clamping plate 322. The elastic member 323 pushes the clamping plate 322 away from the positioning plate 321 in a natural state, so that there is a gap between the clamping plate 322 and the positioning plate 321.

[0042] Reference Figure 1 and Figure 4 Initially, the positioning plate 321 is located directly below the clamping plate 322, and the label is on the feeding roller 2 (reference Figure 2) passes through the gap between the clamping plate 322 and the positioning plate 321, and then operates the rack 33 to move vertically, so that the rack 33 drives the gear 32 to rotate. When the gear 32 rotates, it drives the end of the label to bend through the clamping plate 322 and the positioning plate 321. The support frame 3 is connected with a resistance block 35 along the vertical sliding. The support frame 3 is also equipped with a cylinder 2 351 for driving the resistance block 35 to move. When the label is flipped, the clamping plate 322 is directly opposite to the resistance block 35. At this time, the cylinder 2 351 is controlled to drive the resistance block 35 to approach the clamping plate 322, and push the clamping plate 322 to approach the positioning plate 321, so that the clamping plate 322 and the positioning plate 321 cooperate to clamp and position the end of the label. After clamping the end of the label, the feeding roller 2 continues to drive the label material roll to unwind, so that the label continues to bend along the bend, thereby realizing the folding of the label.

[0043] Reference Figure 1 and Figure 4 The support frame 3 is vertically slidably connected with a cutting knife 34, and the projection of the cutting knife 34 on the horizontal plane is located on the side of the gear 32 close to the unloading roller 11. The support frame 3 is equipped with a cutting cylinder 341 for driving the cutting knife 34 to move. The cutting cylinder 341 is connected to the control center. When the detection device 75 detects that the conveying length of the label reaches the threshold, the feeding roller 2 stops continuing to pull the label to move. At this time, the bent part of the label reaches the standard, and the control center controls the cutting cylinder 341 to drive the cutting knife 34 to move, so that the cutting knife 34 can accurately cut the label.

[0044] Reference Figure 1 and Figure 2 The upper end of the frame 1 is also fixed with a support plate 42, which is located on the side of the support frame 3 away from the unloading roller 11. The frame 1 is provided with a hot pressing plate 41, which is located above the support plate 42. The frame 1 is equipped with a hot pressing motor for driving the hot pressing plate 41 to approach or move away from the support plate 42. The lower end of the hot pressing plate 41 is provided with a heating block, which heats the hot pressing plate 41 when working. The upper end of the frame 1 is fixed with a guide rail 12, which is arranged along the direction of the support frame 3 pointing to the support plate 42, and the guide rail 12 is parallel to the label conveying direction.

[0045] Reference Figure 1 and Figure 5The frame 1 is provided with a feeding clamp 5 which moves along the guide rail 12. The feeding clamp 5 includes an upper clamp 51, a lower clamp 52, a transverse frame 53 and a longitudinal frame 54. The longitudinal frame 54 is slidably connected to the guide rail 12 along the length direction of the guide rail 12. The guide rail 12 is installed with a driving member 13. The driving member 13 is a motor and a lead screw. The lead screw is arranged parallel to the guide rail 12 and is rotatably connected to the guide rail 12. The lead screw passes through the longitudinal frame 54 and is threadedly connected to the longitudinal frame 54. The motor is fixedly connected to the guide rail 12, and the motor output shaft is coaxially fixed with the lead screw. When the motor is working, it drives the lead screw to rotate, so that the lead screw pushes the longitudinal frame 54 to move along the guide rail 12.

[0046] Reference Figure 1 and Figure 5 The transverse frame 53 is slidably connected to the longitudinal frame 54 along a direction perpendicular to the length direction of the guide rail 12. When the longitudinal frame 54 moves, it drives the transverse frame 53 to move. The longitudinal frame 54 is equipped with a second driving member 55. The second driving member 55 is a cylinder. The second driving member 55 is used to push the transverse frame 53 to move, so that the transverse frame 53 is close to or away from the support plate 42.

[0047] Reference Figure 1 and Figure 5 The traverse frame 53 is equipped with a clamping cylinder 531, and a lifting cylinder 532 is arranged between the traverse frame 53 and the clamping cylinder 531. The lifting cylinder 532 is fixedly connected to the traverse frame 53, and the clamping cylinder 531 is slidably connected to the traverse frame 53 in the vertical direction, and the output end of the lifting cylinder 532 is fixedly connected to the clamping cylinder 531. The lower clamping jaw 52 is fixedly connected to the clamping jaw cylinder 531, and the lower clamping jaw 52 is perpendicular to the guide rail 12. When the clamping jaw cylinder 531 moves, it drives the lower clamping jaw 52 to move. The upper clamping jaw 51 is located above the lower clamping jaw 52. The output end of the clamping jaw cylinder 531 is fixedly connected to the upper clamping plate. When the clamping jaw cylinder 531 works, it drives the upper clamping jaw 51 to approach or move away from the lower clamping jaw 52.

[0048] Reference Figure 1 and Figure 5 In the initial state, the longitudinal frame 54 is located at one end of the guide rail 12 close to the support frame 3, and the transverse frame 53 is located close to the guide rail 12. At this time, the upper clamp 51 is away from the lower clamp 52, and the label is directly opposite to the gap between the upper clamp 51 and the lower clamp 52. After the cutting knife 34 cuts the label, the transverse frame 53 is driven away from the guide rail 12 by the driving member 2 55, so that the transverse frame 53 drives the upper clamp 51 and the lower clamp 52 to approach the label. When the label is between the upper clamp 51 and the lower clamp 52, the clamp cylinder 531 drives the upper clamp 51 and the lower clamp 52 to cooperate to clamp the bent label.

[0049] Reference Figure 4 and Figure 5, manipulate the abutment block 35 away from the clamping plate 322, so that the clamping plate 322 is away from the positioning plate 321 under the action of the elastic member 1 323, thereby releasing the clamping of the label, and driving the longitudinal moving frame 54 along the guide rail 12 away from the support frame 3 through the driving member 13 (refer to Figure 1 ), so that the upper clamping jaw 51 and the lower clamping jaw 52 cooperate to drive the label to move above the support plate 42. When the longitudinal moving frame 54 moves, the rack 33 is operated to reset, so that the gear 32 drives the positioning plate 321 and the clamping plate 322 to return to the initial state, and the feeding roller 2 (reference Figure 2 ) continues to drive the label to move toward the gap between the positioning plate 321 and the clamping plate 322.

[0050] Reference Figure 1 and Figure 5 The upper end of the support plate 42 is provided with an escape groove 422. When the lower clamp 52 moves to the top of the escape groove 422, the lifting cylinder 532 drives the clamp cylinder 531 to move downward, so that the clamp cylinder 531 drives the lower clamp 52 to enter the escape groove 422. The hot pressing cylinder 43 drives the hot pressing plate 41 downward, so that the hot pressing plate 41 and the support plate 42 cooperate to press the end of the label, thereby reducing the probability of the folded label being reset under the action of its own elasticity.

[0051] Reference Figure 1 and Figure 5 The frame 1 is also provided with a re-pressing plate 14, which is located on the side of the hot pressing plate 41 away from the support frame 3. A re-pressing cylinder 141 is installed on the upper end of the frame 1, and the output end of the re-pressing cylinder 141 is fixedly connected to the re-pressing plate 14. During the hot pressing process of the label, the re-pressing cylinder 141 is operated to drive the re-pressing plate 14 to move downward, so that the re-pressing plate 14 and the support plate 42 cooperate to press the label, and then the label is folded again, thereby improving the folding effect of the label.

[0052] Reference Figure 1 and Figure 6 A material storage box 6 is installed on the side of the frame 1 away from the material discharge roller 11. The material storage box 6 has a storage cavity for placing labels. The material storage box 6 is slidably connected to a carrier plate 62 along the length direction of the storage cavity. An elastic member 63 is provided between the carrier plate 62 and the material storage box 6. The elastic member 63 is a spring. One end of the spring is fixedly connected to the carrier plate 62, and the other end is fixedly connected to the material storage box 6. The elastic member 63 pushes the carrier plate 62 to move toward the upper end of the material storage box 6 in a natural state.

[0053] Reference Figure 1 and Figure 6The upper end of the frame 1 is provided with a material taking block 15, which is slidably connected to the frame 1 along the direction of the support plate 42 pointing to the material taking box. An extension block 421 is fixedly connected to one side of the support plate 42. When the material taking block 15 moves, it passes over the extension block 421. The frame 1 is provided with a transverse cylinder 151 for driving the material taking block 15 to move. The lower end of the material taking block 15 is provided with a grab plate 16, and the material taking block 15 is installed with a vertical cylinder 162. The output end of the vertical cylinder 162 is fixedly connected to the grab plate 16. When the material taking block 15 moves, the grab plate 16 is driven to move by the vertical cylinder 162. When the vertical cylinder 162 is working, it drives the grab plate 16 to move close to or away from the extension block 421.

[0054] Reference Figure 1 and Figure 6 , a plurality of suction cups 161 are arranged at the lower end of the grab plate 16, and a vacuum device 17 is installed on the frame 1. The vacuum device 17 is provided with a hose connected to the suction cup 161. When the vacuum device 17 is working, the suction cup 161 is made to generate adsorption force through the hose. After the label is hot pressed and folded twice, the transverse frame 53 is driven to approach the guide rail 12 by the second driving member 55, so that the upper clamping jaw 51 and the lower clamping jaw 52 cooperate to drive the label to move toward the extension block 421. The grab plate 16 is initially located directly above the extension block 421. At this time, the grab plate 16 is driven to approach the extension block 421 by the vertical cylinder 162, and the suction cup 161 adsorbs the label after contacting the label.

[0055] Reference Figure 1 and Figure 6 After the label is adsorbed, the upper clamp 51 and the lower clamp 52 are operated to separate from the label. At this time, the vertical cylinder 162 drives the suction cup 161 to move upward through the grab plate 16, thereby driving the label away from the extension block 421. The lateral cylinder 151 drives the material taking block 15 to move, so that the grab plate 16 drives the label to move toward the placement cavity 61 of the material storage box 6 through the suction cup 161. When the label moves to the top of the placement cavity 61, the vertical cylinder 162 drives the grab plate 16 and the label to move downward.

[0056] Reference Figure 1 and Figure 6 A pressing plate 64 is provided at the upper end of the material storage box 6. The pressing plate 64 is rotatably connected to the material storage box 6 in the vertical direction. A torsion spring 641 is provided between the material storage box 6 and the pressing plate 64. One end of the torsion spring 641 is fixedly connected to the pressing plate 64, and the other end is fixedly connected to the material storage box 6. The torsion spring 641 pushes the pressing plate 64 to rotate toward the bearing plate 62 in a natural state. The pressing plate 64 contacts the material storage box 6 in the maximum position and is in a horizontal state. A connecting rod 65 is hinged at the upper end of the pressing plate 64. A moving block 651 is provided at one end of the connecting rod 65 away from the pressing plate 64. A limiting groove is opened vertically in the material storage box 6. The moving block 651 is located in the limiting groove and is slidably connected to the material storage box 6 along the length direction of the limiting groove. When the moving block 651 moves, the pressing plate 64 is driven to rotate through the connecting rod 65.

[0057] Reference Figure 1 and Figure 6 The material storage box 6 is also connected with an adjustment block 66 in a vertical sliding manner. The adjustment block 66 is located above the pressure plate 64. The material storage box 6 is provided with a slide groove adapted to the adjustment block 66. One end of the adjustment block 66 passes through the slide groove and is located in the storage cavity. After the grab plate 16 enters the storage cavity, it is close to the adjustment block 66. A linkage rod 67 is provided between the adjustment block 66 and the moving block 651. The middle position of the linkage rod 67 is rotatably connected to the material storage box 6. The linkage rod 67 is provided with a moving groove 672 along the length direction. The adjustment block 66 and the moving block 651 are both fixedly connected with a rotating rod 671. The two rotating rods 671 are respectively inserted into the two moving grooves 672, and the rotating rod 671 is slidably connected with the linkage rod along the length direction of the moving groove 672. Under the connection between the rotating rod 671 and the moving groove 672, when the adjustment block 66 moves down, the moving block 651 is driven to rise through the linkage rod 67.

[0058] Reference Figure 1 and Figure 6 In the initial state, the pressing plate 64 is in a horizontal state. At this time, the moving block 651 is located near the pressing plate 64, and the adjusting block 66 is above the moving block 651. When the material picking plate contacts the adjusting block 66, the adjusting block 66 is driven to move downward. The adjusting block 66 drives the moving block 651 to move upward through the linkage rod 67. At this time, the pressing plate 64 rotates upward under the action of the connecting rod 65, thereby avoiding the label under the grabbing plate 16. The grabbing plate continues to move downward. When the label moves to the bottom of the pressing plate 64 and contacts the carrying plate 62, the suction cup 161 is operated to stop adsorbing the label. The grabbing plate 16 is operated to move upward. At this time, the pressing plate 64 is reset under the action of the torsion spring 641. The carrying plate 62 and the pressing plate 64 cooperate to clamp and position the label, which is conducive to improving the pressing stability of the label, and then the label is pressed and shaped.

[0059] The working principle of an automatic label folding and pasting device in an embodiment of the present application is as follows: the support roller 22 and the driving roller 23 are coordinated to drive the label to move, so that the label material roll is unrolled under the support of the unwinding roller 11, and after one end of the label passes through between the clamping plate 322 and the positioning plate 321, the gear 32 is driven to rotate by the rack 33, so that the clamping plate 322 and the positioning plate 321 drive the end of the label to bend, and after the gear 32 rotates, the clamping plate 322 is opposite to the resistance block 35, and the resistance block 35 is manipulated to be close to the clamping plate 322, so that the clamping plate 322 and the positioning plate 321 cooperate to clamp and position the label. The label is driven to continue to move by the driving roller 23, so that the label is bent in a state where the end is restricted, and the conveying length of the label is monitored by the detection device 75. When the length of the bent label reaches the standard, the folded label is cut by the cutting knife 34, and the feeding clamp 5 transfers the folded label to the top of the support plate 42, and the open end of the label is pressed by the hot pressing plate 41, and the label is pressed again by the re-pressing plate 14 to position the label and reduce the probability of the label being reset again after being folded. It is more convenient to store the label, which is conducive to improving the convenience of folding the label.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
