Description

Technical Field

[0001] The present application relates to the technical field of label processing, and in particular to an automatic label die-cutting machine. Background Art

[0002] Labels are used to indicate product information. During the label production process, the product is printed on a paper tape. Depending on the size of the label, multiple labels will be arranged side by side along the length of the paper tape. The paper tape is placed in a die-cutting machine, which will cut the labels into independent labels.

[0003] At present, the existing automatic label die-cutting machine includes a frame, a pressing mechanism, a roller mechanism and a cutting mechanism; the pressing mechanism is slidably connected to the frame and is used to press the paper; the roller mechanism includes a roller assembly and a roller drive assembly, the roller mechanism is rotatably connected to the frame and is used to transfer the paper tape; the cutting mechanism includes a cutting assembly and a cutting drive assembly, the cutting mechanism is slidably connected to the frame and is used to cut the label.

[0004] When in use, place the paper strip at the entrance of the automatic die-cutting machine, start the roller drive assembly, the roller drive assembly will drive the roller assembly to rotate and transfer the paper tape. When the paper tape is under the pressing mechanism, start the cutting drive assembly, and the cutting drive assembly will drive the cutting assembly to cut the trademark on the paper tape.

[0005] With respect to the above-mentioned related technologies, the inventor believes that when cutting labels, the movement of the cutting mechanism inevitably causes the paper tape to deflect as the cutting mechanism moves, thereby affecting the cutting accuracy. Utility Model Content

[0006] In order to solve the problem that the movement of the cutting mechanism causes the paper tape to deflect and affects the cutting accuracy, the present application provides an automatic label die-cutting machine.

[0007] This application provides an automatic label die-cutting machine, which adopts the following technical solutions:

[0008] A label automatic die-cutting machine includes a frame, a roller mechanism arranged on the frame and used to convey labels, a pressing mechanism arranged on the frame and used to press labels, a cutting mechanism and a limiting mechanism arranged between the roller mechanism and the pressing mechanism, the limiting mechanism includes two limiting components for limiting the movement of labels and a driving component for driving the limiting components to move, and the limiting components are all installed on the driving component.

[0009] By adopting the above technical solution, the label is placed at the entrance of the die-cutting machine, and the roller mechanism and the limit mechanism are driven to operate synchronously, wherein the roller mechanism sends the label through between the two limit components to the bottom of the pressing mechanism. The pressing mechanism presses the label to reduce the wrinkles of the label. The driving component drives the limit assembly to move so that the distance between the two limit components is the same as the size of the label. Then, the cutting mechanism cuts the label. After the cutting is completed, the label is taken out from the outlet, and the cutting of the label is finally completed.

[0010] During the die-cutting process, labels are subject to displacement due to the cutting mechanism. The limiting components within the limiting mechanism, located on either side of the label, limit the label, reducing deflection and improving cutting accuracy. Simultaneously, the drive assembly drives the two limiting components to move, changing the distance between them. This allows for positioning of labels of varying sizes, expanding the application range of the limiting mechanism.

[0011] Optionally, the limiting mechanism is located between the roller mechanism and the cutting mechanism.

[0012] By adopting the above technical solution, the limiting mechanism is installed between the roller mechanism and the cutting mechanism, which can limit the label when it just passes through the roller mechanism, reducing the deflection generated when the roller mechanism transmits the label, and making it easier for the cutting mechanism to position and cut during cutting, thereby improving the cutting effect.

[0013] Optionally, the driving assembly includes a bidirectional screw rod arranged in a horizontal direction and a driving motor for driving the screw rod to rotate, the bidirectional screw rod is rotatably connected to the frame, the bidirectional screw rod includes a first rotating part and a second rotating part with opposite thread rotation directions, the limiting assembly includes a limiting plate, a guide member for guiding the movement of the limiting plate and a sliding block fixedly connected to the guide member, one sliding block is threadedly and slidably connected to the first rotating part, and the other sliding block is threadedly and slidably connected to the second rotating part; in the starting position, the two sliding blocks are symmetrical along the vertical center axis of the bidirectional screw rod, and the guide member is used to guide the limiting plate to perform linear motion.

[0014] By adopting the above technical solution, the driving component is used to drive the two limit components to slide synchronously and in opposite directions on the bidirectional screw rod, thereby adjusting the distance between the two limit components and realizing the limitation of labels of different sizes. The use of the bidirectional screw rod realizes the movement of the two limit components on the same screw rod. Compared with installing a limit component on a unidirectional screw rod, the use of the bidirectional screw rod saves manufacturing costs.

[0015] Optionally, the limiting assembly further includes a pressing member for pressing the label, and the pressing member is connected to the limiting plate.

[0016] By adopting the above technical solution, the pressing member is used to press the label. Under the action of the pressing member, the surface flatness of the label is improved, which is conducive to the cutting mechanism to cut the label.

[0017] Optionally, the pressing member includes a pressing rod and a pressing wheel for pressing the label, one end of the pressing rod is connected to the limiting plate, and the other end is hinged to the pressing wheel.

[0018] By adopting the above technical solution, the pressing wheel will rotate during the process of the roller mechanism conveying the label, and rolling friction will be generated between the label and the pressing wheel, thereby reducing the impact of the pressing member on the label conveyance.

[0019] Optionally, an anti-scratch layer is provided on the outer side of the pressing wheel.

[0020] By adopting the above technical solution, the provision of the anti-scratch layer reduces the damage to the label surface caused by the pressing wheel, thereby reducing the situation where the label cannot be used due to damage to the label surface, thereby improving the label yield.

[0021] Optionally, the pressing rod includes a guide tube, a connecting rod inserted into the guide tube and slidably connected to the guide tube, a fixing plate is provided at one end of the guide tube away from the connecting rod, a support plate is provided at one end of the connecting rod away from the guide tube, a spring is provided on the guide tube and the connecting rod, one end of the spring abuts against the fixing plate, and the other end abuts against the support plate.

[0022] By adopting the above technical solution, the telescopic design of the pressing rod is used to press labels of different thicknesses. In the initial state, the spring is in a free state. When labels of different thicknesses move to the bottom end of the pressing wheel, the spring will be in different compression states, thereby generating different elastic forces to press the labels.

[0023] Optionally, the pressing member is provided with a guide plate for guiding the movement of the paper, one end of the guide plate is fixedly connected to the pressing member, and the other end extends to the side of the roller mechanism close to the limiting mechanism.

[0024] By adopting the above technical solution, the guide plate is used to guide the label from the outlet end of the roller mechanism to the bottom of the pressing wheel, avoiding the situation where the label fails to enter under the pressing wheel during the transmission process, thereby improving the label cutting effect.

[0025] Optionally, the top portion of the guide plate is arc-shaped.

[0026] By adopting the above technical solution, the top of the guide plate is in an arc shape, so that the label slides along the bottom of the guide plate, which is conducive to guiding the label to the bottom of the pressing wheel.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Placing the label between the two limit components can reduce the deviation of the label caused by the movement of the cutting mechanism, thereby improving the cutting accuracy;

[0029] 2. The driving component is used to adjust the distance between the two limit components, thereby limiting the movement of different labels. Therefore, the cutting mechanism can cut labels of different widths, and the pressing member can press labels of different thicknesses through the spring, which increases the application range of the limit mechanism.

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The embodiment of the present application discloses an automatic label die-cutting machine. Figure 1 and Figure 2 The automatic label die-cutting machine includes a frame 1, a roller mechanism 2 arranged on the frame 1 and used to transmit labels, a pressing mechanism 3 arranged on the frame 1 and used to press labels, a cutting mechanism 4 arranged between the roller mechanism 2 and the pressing mechanism 3, and a limiting mechanism 5 arranged between the roller mechanism 2 and the cutting mechanism 4.

[0040] The roller mechanism 2 includes a motor and two transmission wheels. Both ends of each transmission wheel are rotatably connected to the frame 1. A gear is fixedly installed at one end of each transmission wheel, and the two gears of the two transmission wheels are meshed for transmission. The output end of the motor is connected to one end of one of the transmission wheels near the gear through a conveyor belt. When the motor is started, the motor will drive the transmission wheel to rotate, and the two rollers will rotate relative to each other through the gear transmission; the pressing mechanism 3 includes a pressing roller extending in the horizontal direction, and both ends of the pressing roller are rotatably connected to the frame 1; the cutting mechanism 4 includes a cutting assembly for cutting and a moving assembly for moving the cutting assembly; since the roller mechanism 2, the pressing mechanism 3 and the cutting mechanism 4 are existing technologies, they are not described in detail in the embodiment.

[0041] Reference Figure 3 and Figure 4 The limiting mechanism 5 includes two limiting assemblies 51 for limiting the movement of the label and a driving assembly 52 for driving the limiting assemblies 51 to move. The limiting assemblies 51 are mounted on the driving assembly 52. ​​The driving assembly 52 controls the distance between the limiting assemblies 51 by moving the limiting assemblies 51, and transfers the label between the two limiting assemblies 51. The limiting assemblies 51 limit the label position, reducing label deflection and improving cutting accuracy.

[0042] In order to save manufacturing costs and realize synchronous and reverse sliding of the two limit assemblies 51, the driving assembly 52 in this embodiment includes a bidirectional screw rod 521 arranged in the horizontal direction and a driving motor 522 for driving the screw rod to rotate, wherein the bidirectional screw rod includes a first rotating part 5211 and a second rotating part 5212 with opposite thread rotation directions, both ends of the bidirectional screw rod 521 are rotatably connected to the frame 1, and one end of the bidirectional screw rod 521 is fixedly connected to the output end of the driving motor 522, and the bidirectional screw rod 521 and the connecting plate 5131 are perpendicular to each other.

[0043] Each limiting assembly 51 includes a limiting plate 511, a sliding block 512 and a guide 513. The limiting plate 511 is a rectangle extending in the vertical direction. The sliding block 512 is provided with a rotating hole. The sliding block 512 is sleeved in the bidirectional screw rod 521 through the rotating hole, and the two sliding blocks 512 are symmetrical along the vertical center axis of the bidirectional screw rod 521. One sliding block 512 is threadedly and slidably connected to the first rotating part 5211, and the other sliding block 512 is threadedly and slidably connected to the second rotating part 5212.

[0044] The guide member 513 includes two connecting plates 5131 extending in the horizontal direction and two guide rods 5132 arranged in the horizontal direction. The two guide rods 5132 are arranged parallel to each other. The two connecting plates 5131 are both slidably connected to the guide rods 5132. The top end of the connecting plate 5131 is fixedly connected to the bottom end of the limit plate 511, and the bottom end of the connecting plate 5131 is fixedly connected to the top end of the sliding block 512. The limit plate 511 and the sliding block 512 are both located at the center position of the connecting plate 5131. The use of the guide member 513 can realize the linear motion of the limit plate 511.

[0045] The guide rods 5132 are located on both sides of the bidirectional screw rod 521, and the central axes of the guide rods 5132 are parallel to the central axes of the bidirectional screw rods 521. A mounting seat 5133 is fixedly provided at both ends of each guide rod 5132, and one end of the mounting seat 5133 is fixedly connected to the frame 1. Two guide blocks 5134 are slidingly provided on each guide rod 5132 along the length direction of the guide rod 5132. The guide blocks 5134 are all cubes, and the guide blocks 5134 are sleeved on the guide rods 5132. The top ends of the two guide blocks 5134 on the same side of the two guide rods 5132 are fixedly connected to the bottom end of one of the connecting plates 5131.

[0046] During use, the drive assembly 52 drives the slide block 512 to move synchronously along the length of the guide rod 5132 according to the size of the label. The movement of the slide block 512 causes the limit plate 511 to move, so that the distance between the two limit plates 511 is the same as the size of the label. When the driving roller mechanism 2 transfers the label between the two limit assemblies 51, the limit plates 511 and the label are attached, thereby limiting the label. The drive assembly 52 drives the two limit assemblies 51 to move, causing the distance between the two limit assemblies 51 to change, thereby limiting the position of labels of different sizes, thereby expanding the application range of the limit assembly 51.

[0047] Reference Figure 5 and Figure 6The limiting assembly 51 also includes a pressing member 514, which presses the label to increase the flatness of the label surface, making it easier for the cutting mechanism 4 to cut the label. The pressing member 514 is fixedly mounted on the limiting plate 511. In order to enable the pressing member 514 to press labels of different thicknesses, the pressing member 514 is configured as a telescopic pressing member 514. The pressing member 514 includes a pressing rod 5141 arranged in the vertical direction, a support plate 5142 arranged in the horizontal direction, and a fixing plate 5143, wherein the pressing rod 5141 includes a guide tube 51411 and a connecting rod 51412 both arranged in the vertical direction. The connecting rod 51412 is inserted into the guide tube 51411, and the inner wall of the connecting rod 51412 is slidably connected to the guide tube 51411. The connecting rod 51412 is cylindrical in shape.

[0048] Reference Figure 6 and Figure 7 Two stoppers 51413 are fixedly mounted on the side of the connecting rod 51412. The two stoppers 51413 are symmetrically arranged along the central axis of the connecting rod 51412 and are located at the upper portion of the connecting rod 51412. Two stoppers 51414 are formed on the inner wall of the guide tube 51411 to match the outer sides of the stoppers 51413. The stoppers 51414 extend in the same direction as the length of the guide tube 51411 and are symmetrical along the central axis of the guide tube 51411. The stoppers 51414 extend downward from the top of the guide tube 51411, and their length is one-third of the length of the guide tube 51411. The coordinated use of the limiting groove 51414 and the limiting block 51413 allows the pressing rod 5141 to move linearly along the length direction of the limiting groove 51414 without causing the pressing rod 5141 to rotate in the guide tube 51411 .

[0049] Reference Figure 5 and Figure 6 The support plate 5142 is used to connect the guide tube 51411 and the limit plate 511. The support plate 5142 is rectangular in shape. One side of the support plate 5142 is fixedly connected to one side of the limit plate 511. The bottom end of the support plate 5142 is detachably connected to the top end of the guide tube 51411 by screws; the cross-section of the fixing plate 5143 is square, and the fixing plate 5143 is sleeved on the connecting rod 51412 and fixedly connected to the connecting plate 5131. The fixing plate 5143 is close to the bottom end of the connecting plate 5131.

[0050] A spring 5144 is sleeved on the guide tube 51411 and the connecting rod 51412. One end of the spring 5144 is fixedly connected to the top of the fixing plate 5143, and the other end is fixedly connected to the bottom of the support plate 5142. When there is no label under the pressing piece 514, the spring 5144 is in a free state. The spring 5144 is set between the support plate 5142 and the fixing plate 5143 to prevent the spring 5144 from falling off.

[0051] A pressing wheel 5145 is provided at the bottom end of the connecting rod 51412. During label transport, rolling friction is generated between the label and the pressing wheel 5145, thereby reducing the impact of the pressing member 514 on label transport. The pressing wheel 5145 is hinged to the bottom of the connecting rod 51412. The pressing wheel 5145 is a bidirectional wheel with an anti-scratch layer 51451 provided on its outer side. The anti-scratch layer 51451 is made of rubber and is fixedly connected to the pressing wheel 5145 by adhesive.

[0052] During use, when the label is located below the pressing piece 514, the limit block 51413 will slide along the length direction of the limit slot 51414, thereby driving the connecting rod 51412 and the fixing plate 5143 to move, so that the spring 5144 is in a compressed state, thereby generating elastic force on the label, thereby pressing the label. By extending and retracting the pressing piece 514, the pressing of labels of different thicknesses is achieved.

[0053] Reference Figure 2 and Figure 5 The limiting assembly 51 also includes a guide plate 515. The top portion of the guide plate 515 is a smooth arc. After one end of the label passes through the roller mechanism 2, it moves along the top portion of the guide plate 515 to the bottom portion of the pressing wheel 5145. This arc shape prevents the label from bending during movement. One side of the guide plate 515 is fixedly connected to one side of the limiting plate 511. One end of the pressing plate is close to the pressing wheel 5145, and the other end extends to the side of the roller mechanism 2 near the limiting mechanism 5.

[0054] The implementation principle of an automatic label die-cutting machine in an embodiment of the present application is as follows: a label is placed at the entrance of the die-cutting machine, then the roller mechanism 2 and the limiting mechanism 5 operate synchronously, the roller mechanism 2 conveys the label to the limiting mechanism 5, the driving component 52 drives the limiting component 51 to move, so that the distance between the limiting components 51 is equal to the width of the label, after the label passes through the roller mechanism 2, it runs along the bottom end of the guide plate 515 to the bottom of the pressing wheel 5145, the connecting rod 51412 slides upward along the length of the guide tube 51411, causing the spring 5144 to generate elastic force, thereby pressing the label and reducing the wrinkles of the label, when the label is conveyed to the bottom of the pressing mechanism 3, the cutting mechanism 4 cuts the label, and after cutting is completed, the label is conveyed to the exit, completing the cutting of the label. The use of the limiting component 51 can reduce the deflection of the label caused by the movement of the cutting mechanism 4, thereby improving the cutting accuracy. At the same time, the use of the driving assembly 52 and the pressing member 514 enables the limiting mechanism 5 to limit labels of different sizes and thicknesses, thereby increasing the application range of the limiting mechanism 5.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
