Description

Technical Field

[0001] This utility model relates to the technical field of label making, and more specifically, to a cross-cutting mechanism for a label machine. Background Technology

[0002] Label printing machines, also known as self-adhesive label printing machines, were mostly designed for flat-press printing in the early days, resulting in poor printing quality. The biggest advantage of label printing machines is that they can perform multiple processes in one go. Depending on the model and features of the equipment, label printing machines can simultaneously complete processes such as printing, die-cutting, lamination, embossing, hot stamping, varnishing, computer hole punching, waste removal, bonding, sheet cutting, and paper rolling.

[0003] Currently, when trademark machines produce labels, the first step is to laminate the printed trademark labels. After lamination, the labels are manually cut. This process is not only inefficient, but also results in inconsistent edges on the trademark labels, making it impossible to achieve uniform label cutting. Utility Model Content

[0004] The purpose of this utility model is to provide a cross-cutting mechanism for a trademark machine, which effectively controls the yield rate and realizes fully automatic trademark generation, greatly improving the production efficiency of trademark labels, and aims to solve the problems in the prior art.

[0005] This utility model is implemented as follows: a transverse cutting mechanism for a trademark machine includes a transverse cutting housing mounted on a frame. Side plates are provided on both sides of the transverse cutting housing. A storage box is provided on the side of the transverse cutting housing near the side plates. Guide rails are provided on both sides of the interior of the transverse cutting housing. A paper pressing roller is provided on one side of the guide rails, and a lower blade is provided on the other side of the guide rails. A power cutting structure is provided on one side of the transverse cutting housing.

[0006] Furthermore, the power cutting structure includes a transverse cutting motor disposed on one side of the transverse cutting housing, and a paper feed roller synchronous belt is synchronously disposed at the output end of the transverse cutting motor. The paper feed roller synchronous belt drives the paper feed roller at the front of the frame, so that the plastic film roll can move forward sequentially and continuously.

[0007] Furthermore, the output end of the cross-cutting motor is also connected to a connecting rod assembly. One end of the connecting rod assembly is connected to a rocker arm shaft, the end of the rocker arm shaft is connected to an eccentric wheel, and the other end of the connecting rod assembly is connected to a slider, which is adapted to the guide rail.

[0008] Furthermore, an upper blade is provided between the sliders. Under the action of the connecting rod assembly, the rocker arm shaft and the eccentric wheel, the upper blade moves up and down in the guide rail, thereby opening and closing the upper blade and the lower blade, and cutting the input plastic film roll.

[0009] Furthermore, a paper feed roller is provided at the lower part of the pressure roller, and the paper feed roller and the pressure roller work together to flatten the plastic film roll.

[0010] Furthermore, the storage box is provided with a partition, which is adjustable to facilitate the division of space within the storage box.

[0011] Furthermore, a limiting plate is provided at the bottom of the storage box, and a mounting plate is provided on the side of the transversely cut shell away from the limiting plate. Mounting brackets are provided on both sides of the side plate, and the mounting brackets realize the installation and fixation of the transversely cut shell and the frame.

[0012] Compared with the prior art, the cross-cutting mechanism of the trademark machine provided by this utility model has the following beneficial effects:

[0013] 1. By adding an online testing agency to conduct rapid online testing of the initial trademark labels, problematic trademark labels can be identified. The labels detected by the online testing agency can be directly output to the waste label marking agency, which can quickly mark and cut the waste labels. After marking and cutting, the waste label removal agency can quickly remove them. Waste labels can be quickly identified through camera recognition, and the marking, cutting and removal ensure that all subsequent cut trademark labels are qualified products, effectively controlling the yield rate and realizing fully automated trademark generation, greatly improving the efficiency of trademark label production.

[0014] 2. The waste stripping mechanism of the label machine can quickly separate the coated plastic film roll from the waste film. The cutting force generated by the waste stripping component reduces the tensile force during separation, thus avoiding excessive drag on the plastic film roll during separation, which could damage and render it unusable. Since the waste film collection roller is relatively thick, the upward traction force of the waste film will tilt towards the label cutting module. Therefore, it is necessary to adjust the position of the waste stripping component to tilt it towards the label cutting module. The operation method is to loosen the adjustment handle so that the adjustment frame can rotate, thereby adjusting the position of the waste stripping cutting force and ensuring that the cutting force is always at an angle suitable for separating the plastic film roll from the waste film.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] The implementation of this utility model will be described in detail below with reference to specific embodiments.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0044] Reference Figure 1-18 As shown, the fully automatic label machine includes a frame 70. A raw material roller 71 is located on the lower side of one side of the frame 70. A plastic film roll is fitted onto the raw material roller 71. The plastic film roll is connected to a label cutting module 8 via multiple drive rollers. The label cutting module 8 cuts the label borders on the laminated plastic film roll, thus separating each label from the border film. A label machine waste removal mechanism 10 is located at one end of the label cutting module 8. The waste removal mechanism 10 separates the laminated plastic film roll from the border film, thus separating the cut border film from the laminated label. An online detection mechanism 20 is located on one side of the waste removal mechanism 10. The online detection mechanism 20 is used to perform online detection of the printed label pattern on the laminated plastic film roll, detecting the printed label on the plastic film roll. Whether the pattern meets the production standards is determined by quickly locating the defective labels. One side of the online detection mechanism 20 is connected to the defective label marking mechanism 30, which quickly cuts the defective labels located by marking them with a circle and cutting them. One side of the defective label marking mechanism 30 is connected to the defective label removal mechanism 40, which removes the trademarks marked and cut by the defective label marking mechanism 30. One side of the defective label removal mechanism 40 is equipped with a vertical cutting mechanism 50, which vertically cuts the qualified trademark labels, causing the trademark labels to be separated vertically. One side of the vertical cutting mechanism 50 is connected to a horizontal cutting mechanism 60, which horizontally cuts the vertically separated labels, finally completing the output of a single label block.

[0045] In this embodiment, a film roller 72 is provided on the frame 70 above the label cutting module 8. The film roller 72 is bonded to the plastic film roll through the extrusion roller on the frame 70. The label cutting module 8 cuts the film attached to the plastic film roll, so that each trademark label is independently bonded to the film. The label machine waste removal mechanism separates the frame film from the plastic film roll. The waste film collection roller 73 on the label machine waste removal mechanism 10 collects the frame film roll. At this time, the trademark labels on the plastic film rolls of the label machine waste removal mechanism 10 are all attached with film, and the edges of the plastic film rolls are in a film-free state.

[0046] In this embodiment, the waste removal mechanism 10 of the trademark machine includes a waste removal frame 11 fixed on the frame 70. The waste removal frame 11 is provided with four fixing members 12 on its bottom side. The fixing members 12 are fixed to the frame 70 by bolts. A driven roller 13 is provided on one side of the lower part of the waste removal frame 11. A waste removal roller 14 is provided on the waste removal frame 11 above the driven roller 13. A connecting roller 15 is provided on the waste removal frame 11 below the waste removal roller 14. The plastic film roll passes through the driven roller 13 to the waste removal roller 14, turns, and then passes out from the lower part of the connecting roller 15. A waste removal device is provided on the upper part of the waste removal roller 14.

[0047] In this embodiment, the waste stripping device includes an adjustment frame 17 fixed on both sides of the waste stripping roller 14, a waste stripping component 16 is arranged between the adjustment frames 17, and a peeling part 19 is arranged at the lower part of the waste stripping component 16. The peeling part 19 faces the waste stripping roller 14. In this way, when the plastic film roll is separated from the label and the waste film, a positive cutting force is achieved, so that the label and the waste film are quickly separated, avoiding damage to the plastic film roll caused by hard dragging. Furthermore, an adjustment handle 18 is arranged on one side of the adjustment frame 17. The adjustment handle 18 passes through the adjustment frame 17 and extends to the fixed shafts on both sides of the waste stripping roller 14. The adjustment handle 18 limits the adjustment resistance of the adjustment frame 17 on the waste stripping roller 14. If the adjustment handle 18 is tightened, the external force required for the peeling part 19 to adjust its position is greater, so that the peeling part 19 is more stable, ensuring that the probability of the peeling part 19 being deviated by external force when it is positioned at the optimal cutting force position is reduced.

[0048] Specifically, if the thickness of the waste film collection roller 73 is large, the waste stripping mechanism 10 of the trademark machine realizes the automatic adjustment of the resistance torque of the waste stripping part 16 relative to the waste stripping roller. When the radius of the waste roll changes, the winding resistance distance also changes, and the resistance and orientation of the stripping part 19 also change accordingly. The winding resistance distance will force the stripping part 19 to change its orientation to adapt to the current thickness of the waste film collection roller 73, so that the waste stripping force of the stripping part 19 is ideal.

[0049] In this embodiment, the online inspection mechanism 20 includes an inspection base 21 fixed on the frame 70. An inspection box 22 is provided on the upper part of the inspection base 21. An inspection camera 23 is provided at the top of the inspection box 22. The inspection camera 23 faces the plastic film roll at the bottom. An observation port 24 is provided on one side of the inspection box 22. A sealing plate 25 is provided outside the observation port 24. The sealing plate 25 is an acrylic plate, which can reduce the entry of external light and can also achieve internal sealing of the online inspection mechanism 20, so as to take pictures of the labels on the plastic film roll to determine whether they are qualified.

[0050] In this embodiment, the waste label marking mechanism 30 includes a marking track 31 set on the frame 70. One end of the marking track 31 is equipped with a servo motor to realize the transmission connection between the marking trolley that matches the marking track 31 and the output power to realize the marking trolley to move left and right on the marking track 31, and to mark and cut the unqualified trademarks detected on the bottom plastic film roll.

[0051] In this embodiment, the marking trolley includes a detection control board 32. The detection control board 32 receives external signals and outputs execution signals to unqualified trademarks, completing the marking and cutting action of the unqualified trademarks. The detection control board 32 is fixed on the trolley's main mounting plate 310. A plurality of sliding pressure rollers 34 are provided on one side of the trolley's main mounting plate 310. The sliding pressure rollers 34 are all arranged in the marking track 31. Synchronous belt clamping blocks 37 are arranged between the sliding pressure rollers 34. The synchronous belt clamping blocks 37 extend into the marking track 31 to limit the direction of the sliding pressure rollers 34 when they slide. To prevent displacement, a motor mounting plate 38 is provided on the other side of the main mounting plate 310. An eccentrically cut motor bracket is fixed on the motor mounting plate 38, and an eccentrically cut motor 33 is mounted on the eccentrically cut motor bracket. A coupling sleeve 320 is installed downwards along the output shaft of the eccentrically cut motor 33. A splined shaft 316 is nested at the lower end of the coupling sleeve 320. The splined shaft 316 passes through the bearing mounting plate 314 and extends downwards. A deep groove bearing 313 is installed inside the bearing mounting plate 314. The deep groove bearing 313 is adapted to the splined shaft 316, thus preventing displacement. When the key shaft 316 rotates, the friction is reduced by the deep groove bearing 313. A bearing pressure plate 315 is provided on the upper part of the spline shaft 316. Multiple positioning bolts are provided on the outside of the bearing pressure plate 315. The positioning bolts position the bearing pressure plate 315 on the spline shaft 316 and limit the downward movement of the spline shaft 316 during marking and cutting. A spline shaft seat 321 is provided at the bottom of the spline shaft 316. An offset groove 322 is provided at the bottom end of the spline shaft seat 321. An adjusting nut is provided on the outer wall of the spline shaft seat 321. The adjusting nut is equipped with a pressure device. Spring 317, pressure spring 317 abuts against positioning ball 318, one side of positioning ball 318 extends to the inner wall of offset groove 322, cutting blade 319 is provided in offset groove 322, cutting blade 319 extends downward and the blade head faces the plastic film roll paper, the deformation of pressure spring 317 is adjusted by adjusting nut to adjust the squeezing force of positioning ball 318 pressing the inner wall of offset groove 322, ball groove is provided on the upper part of cutting blade 319, ball groove is adapted to positioning ball 318 to complete the fixation of cutting blade 319 in offset groove 322;

[0052] In this embodiment, since the spline shaft 316 and the coupling sleeve 320 both rotate around the axis, and the bottom wall dot of the offset groove 322 is not located on the axis, when the spline shaft 316 rotates, the cutting blade 319 in the offset groove 322 rotates around the axis. When the whole action is completed, a corresponding circular mark will be drawn on the plastic film roll. The radius R of this circle is the horizontal projection distance between the rotation axis and the bottom wall dot of the offset groove 322.

[0053] In this embodiment, a voice coil motor frame is provided on one side of the motor mounting plate 38, and a voice coil motor 36 is mounted on the voice coil motor frame. A movable frame is provided at the output end of the voice coil motor 36. Magnet mounting frames 312 are provided on both sides of the voice coil motor 36. One side of the magnet mounting frame 312 is fixed to the motor mounting plate 3. Linear bearings 311 are provided on both sides of the magnet mounting frame 312. A guide post 39 is provided through the linear bearing 311. A return spring 35 is sleeved on the outer wall of the guide post 39 located on the upper part of the magnet mounting frame 312. The top end of the guide post 39 is connected to the movable frame, and the bottom end of the guide post 39 is connected to the bearing mounting plate 314. When marking is required... The voice coil motor 36 acts to attract the moving frame downwards, which in turn moves the guide post 39 downwards. The guide post 39 then moves the bearing mounting plate 314 downwards in sync, which in turn moves the cutting blade 319 downwards, bringing the bottom of the cutting blade 319 into contact with the plastic film roll. At this point, the eccentric cutting motor 33 drives the spline shaft seat 321 of the spline shaft 316 to move the cutting blade 319 in an eccentric circular motion. After marking is completed, a stop signal is sent to the voice coil motor 36. Under the action of the return spring 35, the guide post 39 moves upwards, which in turn moves the bearing mounting plate 314 upwards, separating the bottom of the cutting blade 319 from the plastic film roll, thus completing the marking and cutting of the waste label.

[0054] The waste label marking method based on rotational cutting completes the waste label marking process through the aforementioned waste label marking mechanism 30, specifically including the following steps:

[0055] S11: Receive the defective label positioning data output by the online detection agency 20, and control the marking trolley to move on the marking track 31 to the position of the defective label positioning data;

[0056] S12: The detection control board 32 receives the marking signal and sends a start signal to the voice coil motor 36. The voice coil motor 36 acts to attract the moving frame downward. The moving frame drives the guide post 39 to move downward. The guide post 39 drives the bearing mounting plate 314 to move downward synchronously.

[0057] S13: The bearing mounting plate 314 drives the cutting blade 319 to move downward, so that the bottom of the cutting blade 319 comes into contact with the plastic film roll paper;

[0058] S14: At this time, the eccentric cutting motor 33 drives the spline shaft seat 321 of the spline shaft 316 to drive the cutting blade 319 to perform an eccentric circular motion. After the marking is completed, the voice coil motor 36 sends a termination signal. Under the action of the return spring 35, the guide post 39 moves upward, driving the bearing mounting plate 314 to move upward, so that the bottom of the cutting blade 319 is separated from the plastic film roll, thus completing the marking and cutting of the waste label.

[0059] In this embodiment, the waste label discharge mechanism 40 includes a mounting frame 41 fixed on a support plate 51. A connecting buckle 42 is provided on one side of the mounting frame 41, and a connecting post 43 is provided between the connecting buckles 42. Brush bodies 44 are evenly distributed at the lower part of the connecting post 43. A support frame 45 is provided at the lower part of the brush body 44, and a waste discharge groove 46 is provided at the lower part of the support frame 45. When the plastic film roll that has been marked and cut by the waste label moves, the brush body 44 bends and generates a rebound force due to the friction between the brush body 44 and the plastic film roll. After encountering the waste label cut, it will return to its original position and remove the cut label from the waste discharge groove 46 of the support frame 45. At this time, the waste discharge process is completed.

[0060] In this embodiment, the longitudinal cutting mechanism 50 includes a support plate 51 mounted on the frame 70. A damping bearing 54 is provided between the opposing sides of the two support plates 51. A longitudinal cutting shaft 55 is provided between the damping bearings 54. A plurality of fixing clamps 56 are evenly distributed on the longitudinal cutting shaft 55. An adjusting member 57 is provided on one side of the fixing clamp 56 to adjust the position of the fixing clamp 56. A longitudinal cutting guide 58 is provided on the other side of the fixing clamp 56. A cutting head 59 is provided at the lower end of the longitudinal cutting guide 58. The cutting head 59 is in contact with the plastic film roll. A supporting rotating roller 510 is provided directly below the cutting head 59 to support the plastic film roll in contact with the cutting head 59 and provide support force for the cutting head 59 during longitudinal cutting.

[0061] In this embodiment, a connecting frame 52 is also provided on the support plate 51 on one side of the longitudinal cutting axis 55. The connecting frame 52 isolates the longitudinal cutting guide 58, and a through-hole 52 is provided in the middle of the connecting frame 52 for external observation of the longitudinal cutting guide 58 cutting the plastic film roll.

[0062] In this embodiment, the transverse cutting mechanism 60 includes a transverse cutting housing 61 mounted on the frame 70. Side plates 62 are provided on both sides of the transverse cutting housing 61. A storage box 63 is provided on the side of the transverse cutting housing 61 near the side plates 62. Guide rails 611 are provided on both sides of the interior of the transverse cutting housing 61. A paper pressing wheel 69 is provided on one side of the guide rails 611, and a lower blade 612 is provided on the other side of the guide rails 611. A power cutting structure is provided on one side of the transverse cutting mechanism 60.

[0063] In this embodiment, the power cutting structure includes a transverse cutting motor 68 disposed on one side of the transverse cutting housing 61. The output end of the transverse cutting motor 68 is synchronously provided with a paper feed roller synchronous belt 67. The paper feed roller synchronous belt 67 drives the paper feed roller at the front of the frame 70, so that the plastic film roll can move forward sequentially and continuously.

[0064] In this embodiment, the output end of the cross-cutting motor 68 is also connected to a connecting rod assembly 616. One end of the connecting rod assembly 616 is connected to a swing arm shaft 617, and the end of the swing arm shaft 617 is connected to an eccentric wheel 618. The other end of the connecting rod assembly 616 is connected to a slider 615. The slider 615 is adapted to the guide rail 611. An upper blade 614 is provided between the sliders 615. Under the action of the connecting rod assembly 616, the swing arm shaft 617 and the eccentric wheel 618, the upper blade 614 moves up and down in the guide rail 611, thereby realizing the opening and closing of the upper blade 614 and the lower blade 612, and realizing the cutting of the input plastic film roll.

[0065] In this embodiment, a paper feed roller 610 is provided at the lower part of the pressure roller 69. The paper feed roller 610 and the pressure roller 69 work together to flatten the plastic film roll.

[0066] In this embodiment, a partition 613 is provided in the storage box 43. The partition 613 is adjustable to facilitate the division of the space in the storage box 63.

[0067] In this embodiment, a limiting plate 64 is provided at the lower part of the storage box 63, and an installation plate 66 is provided on the side of the transversely cut shell 61 away from the limiting plate 64. Installation brackets 65 are provided on both sides of the side plate 62. The installation brackets 65 realize the installation and fixation of the transverse cutting mechanism 60 and the frame 70.

[0068] In this embodiment, a waste collection roller 74 is provided on the frame 70 above the transverse cutting mechanism 60. The waste collection roller 74 collects the edge plastic film rolls cut by the longitudinal cutting mechanism 50.

[0069] In this embodiment, an operating console 9 is provided on the rack 70 to control the internal system, and a display 91 is also provided on the upper part of the rack 70 to monitor the operating parameters of the equipment.

[0070] This technical solution adds an online inspection agency 20 to perform rapid online inspection of the initial trademark labels. This rapid inspection identifies problematic trademark labels and directly outputs the location of the labels detected by the online inspection agency 20 to the reject label marking agency 30. The reject label marking agency 30 can quickly mark and cut the reject labels. After marking and cutting, the reject label removal agency 40 can quickly remove them. Reject labels can be quickly identified through camera recognition, and the marking, cutting, and removal processes ensure that all subsequently cut trademark labels are qualified products, effectively controlling the yield rate. Furthermore, it achieves fully automated trademark generation, greatly improving the efficiency of trademark label production.

[0071] This technical solution utilizes multi-level control of the cutting equipment to create standardized label films, facilitating automated operation in subsequent processes using digital recognition systems. The label cutting is irregular-shaped cutting, achieved through high-precision motor drives in the X and Y directions, coupled with a Z-axis voice coil motor and a high-precision closed-loop control using a grating ruler. Another characteristic of this irregular-shaped label cutting is that it doesn't cut all the way through. Since labels are mostly plastic-paper self-adhesive printed materials, irregular-shaped label cutting involves cutting one side of the plastic seal without cutting the underlying paper material. This allows for easy peeling of the cut irregular-shaped self-adhesive portion from the substrate, which can then be applied to the desired location. The standard circular markings on the waste labels are also included in the cutting process. Cutting is a completely different cutting method. It involves making a destructive mark on the discovered defective labels, which facilitates quick identification in the next process. The cutting is thorough. It involves a trolley equipped with different rotary motors and eccentric blade holders. When the ordinary motor receives the task of marking the defective label, the trolley automatically travels to the top of the defective label. Driven by its voice coil motor, the trolley carries the blade downwards, and the blade tip embeds into the label material. The ordinary motor outputs a circle or larger than a circle, and the cutting blade will cut a circle of a fixed diameter on the label paper. The eccentric blade holder can be replaced as needed to solve this problem. Under normal circumstances, the diameter is stable. Due to the sharpness of the blade tip, the defective circle usually still sticks to the cardboard after cutting, which requires a special setting to remove the standard circle.

[0072] It adopts high-precision X / Y axis motor drive + Z axis voice coil motor closed-loop control to cut the plastic sealant layer without cutting through the substrate, which is convenient for peeling. It uses an eccentric tool holder + rotary motor to achieve full-through circular hole marking of waste labels, which is convenient for subsequent identification.

[0073] The label stripping mechanism 10 can quickly separate the coated plastic film roll from the waste film. The cutting force generated by the stripping component 16 reduces the tensile force during separation, thus preventing excessive drag on the plastic film roll during separation and causing damage and scrapping. Since the waste film collection roller 73 is relatively thick, the upward traction force of the waste film will tilt towards the label cutting module 8. At this time, it is necessary to adjust the position of the stripping component 16 to tilt towards the label cutting module 8. The operation method is to loosen the adjustment handle 18 so that the adjustment frame 17 can rotate, thereby completing the position adjustment of the stripping cutting force, so that the cutting force is always kept at an angle that matches the separation of the plastic film roll and the waste film.

[0074] In this embodiment, the entire operation process can be controlled by a computer, along with a PLC, to achieve automated operation control. In each operation stage, sensors can be set up to provide signal feedback and ensure that the steps are performed sequentially. These are all conventional knowledge in current automation control, and will not be elaborated on in this embodiment.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
