Description

Technical Field

[0001] The invention relates to the technical field of die-cutting, in particular to a label die-cutting device capable of reducing the relative impact of upper and lower templates. Background Art

[0002] The die-cutting device is an application tool for cutting and cutting workpieces. For example, when mass-producing labels, after the label style forms unique label patterns and text on the paper, due to the printing process of the label patterns and text, the patterns and patterns exist in a preset arrangement, and there are blank areas left; At this time, in order to meet the needs of subsequent label production, processing and use, it is necessary to perform die-cutting operations on the blank spaces remaining on the paper after superposition to form effective labels without excessive invalid residues.

[0003] Existing die-cutting devices are mostly divided into small manual label die-cutting processing equipment and large unified die-cutting cutting equipment after a large number of labels are piled up. In the process of use, both of them are manually positioned after the label is positioned, and the excess invalid area is cut by the lifting drive of the cutting blade. This type of die-cutting device has high efficiency, but in the die-cutting process, due to the thickness and size differences of the labels to be die-cut, there are still certain problems in the use process: For example, the die-cutting effect is achieved by driving the tool to rise and fall. When the thickness of the label to be die-cut is too large, the anti-shear force and friction force increase. For this type of label die-cutting, it is often necessary to apply a larger driving kinetic energy to drive the tool. After the tool cuts the label, the anti-shear force and friction force suddenly decrease, and the lower driving force applied by the die-cutting is vertically downward. This process can easily cause impact and vibration of the tool during the die-cutting process, resulting in tool collision and damage. Although the existing lower driving force also provides sensors and supporting pressure relief components to reduce the impact force after the tool cuts the label, its application cost is high, and the tool collision phenomenon caused by impact force also often occurs.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original label die-cutting device. Summary of the invention

[0005] The purpose of the present invention is to provide a label die-cutting device that can reduce the relative impact of upper and lower templates, so as to solve the problem that the existing label die-cutting device proposed in the above background technology needs to apply greater driving kinetic energy.

[0007] Preferably, the working template and the lifting template are arranged relatively parallel, wherein a sensor is arranged between the lifting template and the working template, and the sensor monitors the distance between the two.

[0008] Preferably, a press platform is fixed at the bottom back of the lifting template, the bottom of the press platform and the pressure assembly are located in the same horizontal plane, and the press platform and the lifting template form a relative sliding installation structure.

[0009] Preferably, the lateral hydraulic rods and the middle hydraulic rods are parallel to each other, and the lateral hydraulic rods are symmetrically distributed about the vertical center axis of the middle hydraulic rod, and the internal upper sections of the lateral hydraulic rods and the middle hydraulic rod are controlled by the same hydraulic assembly.

[0010] Preferably, the first connecting member and the output shaft of the lateral hydraulic rod are hingedly connected, and the first connecting member and the slide groove on the die-cutting blade are in a snap-fitting sliding connection; The second connecting member is vertically fixedly connected to the middle hydraulic rod, and the bottom of the second connecting member is hingedly arranged with the middle section of the die-cutting blade.

[0011] Preferably, the output shaft of the lateral hydraulic rod is composed of a sealed telescopic rod, the lower end of the sealed telescopic rod penetrates to the bottom of the lateral hydraulic rod, and the upper end and middle section of the sealed telescopic rod are fixed with sealing plates, and an elastic member is fixed between the sealing plate in the middle section and the bottom inner wall of the lateral hydraulic rod; At the same time, the through connection between the pipeline and the middle section inside the lateral hydraulic rod is located between the sealing plate at the upper end and the middle section of the sealing telescopic rod.

[0012] Preferably, the sealing plate and the lateral hydraulic rod are in a sealed, fitted, sliding connection, and a valve assembly is also installed on the outer wall of the through connection between the pipeline and the lateral hydraulic rod.

[0013] Preferably, one end of an air pressure regulating tube is fixedly penetrated through the upper end of the sealed telescopic rod, and the other end of the air pressure regulating tube penetrates to the outside of the lateral hydraulic rod.

[0014] Preferably, a distance sensor is fixed at the end edge of the die-cutting blade, a liquid pusher plate is movably installed on the outer wall of the pipeline inside the through-connection between the valve assembly and the lateral hydraulic rod, and an electromagnet is fixed inside the through-connection between the valve assembly and the lateral hydraulic rod; The electromagnet is electrically connected to the distance sensor, the liquid pushing plate is magnetically arranged on one side facing the electromagnet, and sealing rings are arranged at the middle and outer edge of the liquid pushing plate.

[0015] Preferably, the hydraulic adjustment assembly includes an inner hollow cavity for positioning and an electric screw assembly rotatably mounted in the middle of the inner hollow cavity, and a liquid sealing plate is threadedly mounted on the outer side of the electric screw assembly; The liquid sealing plate and the inner cavity are in sealed sliding connection, and photoelectric sensors are correspondingly installed at the bottom of the liquid sealing plate and the middle of the inner wall of the inner cavity. Transparent shells are provided at the bottom of the liquid sealing plate and the inner wall of the inner cavity outside the photoelectric sensor.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the label die-cutting device capable of reducing the relative impact of the upper and lower templates can stably complete the die-cutting work when there are many stacked label workpieces, resulting in an increase in the shearing resistance and friction of the label workpieces, and will not cause the die-cutting process to impact the knife. The specific method is as follows: 1. Through the lateral hydraulic rods and the middle hydraulic rods installed through the sliding, the die-cutting blade works synchronously when it moves forward and backward, which is convenient for the subsequent lifting and lowering control of the die-cutting blades at different positions to achieve die-cutting operations. The lateral hydraulic rods and the upper section of the middle hydraulic rod are controlled by hydraulic components, which is convenient for adjusting the synchronous overall lifting. The hydraulic adjustment components are set to act on the left and right ends of the die-cutting blade to make it swing when it is lifted and lowered, thereby improving the cutting efficiency and reducing the impact force during die-cutting; Furthermore, the hydraulic adjustment component controls the reciprocating motion of the liquid sealing plate through the electric screw assembly, so that the oil inside the hydraulic adjustment component is synchronously introduced and exported in the symmetrically distributed lateral hydraulic rods, and is introduced into the space between the two sealing plates. The expansion and contraction control effect of the sealing expansion and contraction rod is achieved through the change of oil pressure, so that the left and right ends of the die-cutting blade are synchronously lifted and lowered in different directions around the hinge node of the second connecting member during the lifting process. Under the action of the synchronous descending driving force of the die-cutting blade during die-cutting, the die-cutting effect is achieved more quickly; 2. When the die-cutting blade is lifted and swung to achieve the die-cutting operation of the label, the valve assembly stabilizes the hydraulic pressure in the middle section of the lateral hydraulic rod, thereby controlling the inclination angle or positioning state of the die-cutting blade. An additional distance sensor is provided. When the die-cutting blade falls and collides with the blade due to the side effect of the impact force during the die-cutting process, the monitoring and control of the electromagnet are activated, causing the push plate to undergo electromagnetically driven displacement, thereby achieving the effect of decompression in the middle section of the lateral hydraulic rod, and the die-cutting blade rebounds to prevent collision with the blade and temporarily reset.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 7 The present invention provides a technical solution: a label die-cutting device capable of reducing the relative impact of upper and lower templates, comprising: an outer support assembly 1, wherein a working template 2 and a lifting template 3 are fixedly installed from the bottom and the top, respectively, wherein the lifting template 3 is driven by a hydraulic assembly at the top of the outer support assembly 1, and hydraulic guide rails 4 are symmetrically installed at the bottom of the lifting template 3, and a pressure assembly 5 is fixed between the hydraulic guide rails 4; the working template 2 and the lifting template 3 are relatively parallel, wherein a sensor is arranged between the lifting template 3 and the working template 2, and the sensor monitors the distance between the two; In the above technical scheme, the lifting template 3 is driven to rise and fall by the hydraulic component to change the distance between the lifting template 3 and the working template 2. First, the label workpiece to be die-cut can be clamped and positioned between the two by downward pressing. A pressing platform 501 is fixed at the bottom back of the lifting template 3. The bottom of the pressing platform 501 and the pressure component 5 are located in the same horizontal plane. At the same time, the pressing platform 501 and the lifting template 3 form a relatively sliding installation structure. At the same time, the hydraulic guide rail 4 can be used to adjust the front and rear positions of the pressure component 5 and the die-cutting knife 8 for subsequent die-cutting, wherein the pressure component 5 presses the edge of the label workpiece to be die-cut to prevent the edge of the label from curling up and affecting the subsequent die-cutting process.

[0021] The technical scheme also includes: the lateral hydraulic rod 6 and the middle hydraulic rod 7 are installed through the edge and the middle position of the lifting template 3, the lateral hydraulic rod 6 and the middle hydraulic rod 7 are positioned by the pressure assembly 5, and the lower ends of the output shafts of the lateral hydraulic rod 6 and the middle hydraulic rod 7 are respectively movably connected and positioned with the die-cutting knife 8 through the first connecting member 9 and the second connecting member 10; the lateral hydraulic rod 6 and the middle hydraulic rod 7 are parallel to each other, and the lateral hydraulic rod 6 is symmetrically distributed about the vertical center axis of the middle hydraulic rod 7, and the internal upper sections of the lateral hydraulic rod 6 and the middle hydraulic rod 7 are hydraulically controlled by the same hydraulic assembly.

[0022] In the above technical solution, the following is adopted: Figure 3-Figure 7The technical structure shown achieves the installation and positioning of the lateral hydraulic rod 6 and the middle hydraulic rod 7 through the pressure component 5, so that they can move synchronously when in use. The upper sections of the lateral hydraulic rod 6 and the middle hydraulic rod 7 can be hydraulically controlled by the hydraulic component, so that the lateral hydraulic rod 6 and the middle hydraulic rod 7 can be synchronously extended and retracted, and the die-cutting knife 8 can be controlled to perform lifting and lowering to realize the label die-cutting processing.

[0023] Furthermore, in the technical solution, the hydraulic adjustment component 11 is fixed to the top of the outer bracket component 1, and the hydraulic adjustment component 11 adjusts the hydraulic strength of the middle section inside the lateral hydraulic rod 6 through the pipeline; the first connecting member 9 and the output shaft of the lateral hydraulic rod 6 constitute an articulated rotation setting, and the first connecting member 9 and the slide groove on the die-cutting knife 8 are engaged in a sliding connection; wherein the second connecting member 10 and the middle hydraulic rod 7 are vertically fixedly installed and connected, and the bottom of the second connecting member 10 is articulated with the middle section of the die-cutting knife 8; the output shaft of the lateral hydraulic rod 6 adopts a sealed telescopic rod 60 1, the lower end of the sealing telescopic rod 601 penetrates to the bottom of the lateral hydraulic rod 6, and the upper end and the middle section of the sealing telescopic rod 601 are fixed with sealing plates 602, and an elastic member is fixed between the sealing plate 602 in the middle section and the bottom inner wall of the lateral hydraulic rod 6; at the same time, the through connection between the pipeline and the middle section inside the lateral hydraulic rod 6 is located between the sealing plate 602 in the upper end and the middle section of the sealing telescopic rod 601; the sealing plate 602 and the lateral hydraulic rod 6 are in a sealed fitting sliding connection, and a valve assembly 603 is also installed on the outer wall of the through connection between the pipeline and the lateral hydraulic rod 6; In the above scheme, if Figure 8 and Fig. 9 As shown, by using the hydraulic adjustment component 11, the oil is introduced and exported synchronously in different directions in the symmetrically distributed left and right lateral hydraulic rods 6. In this process, the oil passes through the valve component 603 in the liquid cavity between the two sealing plates 602 in the middle section of the lateral hydraulic rod 6 to complete the oil pressure regulation, so that the sealed telescopic rod 601 telescopes under the action of the change of the oil pressure in the middle section, and the telescopic movement states of the sealed telescopic rods 601 corresponding to the left and right lateral hydraulic rods 6 are completely opposite. The telescopic movement of the sealed telescopic rod 601 causes the lower end of the sealed telescopic rod 601 to be hinged and rotatably installed. The second connecting piece 10 engages and slides with the die-cutting blade 8, so that the die-cutting blade 8 swings around the first connecting piece 9 at its central hinge point. When the die-cutting blade 8 is lifted and lowered due to the synchronous extension and retraction of the lateral hydraulic rod 6 and the middle hydraulic rod 7, the left and right ends of the die-cutting blade 8 swing to improve the shearing and cutting effect from the edge to the middle of the label workpiece. Under the driving action of a smaller lifting external force, the die-cutting efficiency and stability of the label are improved, and the die-cutting blade 8 is reduced due to the impact collision of the die-cutting blade 8 caused by the sudden reduction of the anti-shearing external force and the damping friction after the label die-cutting is completed due to excessive lifting driving external force.

[0024] In the above technical scheme, the lifting drive and the swinging shearing drive of the die-cutting knife 8 can also be carried out in steps. At this time, it is only necessary to maintain the stability of the oil pressure in the middle section of the lateral hydraulic rod 6 through the valve assembly 603, so as to achieve a good application effect of the die-cutting knife 8 being lifted and lowered separately. At the same time, in this technical scheme: the upper end of the sealed telescopic rod 601 is also fixed with one end of the air pressure regulating tube 604, and the other end of the air pressure regulating tube 604 passes through the outside of the lateral hydraulic rod 6. Such a setting can enable the sealed telescopic rod 601 to perform telescopic movement, control its internal air pressure, prevent its internal air pressure from becoming unstable, and affect the regulation efficiency of the oil pressure in the middle section of the lateral hydraulic rod 6.

[0025] In the above technical solution, if Fig. 9 It is further provided that: a distance sensor 12 is fixed at the end edge of the die-cutting blade 8, a liquid pusher plate 1201 is movably installed on the outer wall of the pipe inside the through connection between the valve assembly 603 and the lateral hydraulic rod 6, and an electromagnet 1202 is fixed inside the through connection between the valve assembly 603 and the lateral hydraulic rod 6; the electromagnet 1202 is electrically connected to the distance sensor 12, the liquid pusher plate 1201 is magnetically arranged toward one side of the electromagnet 1202, and sealing rings are arranged at the middle and outer edges of the liquid pusher plate 1201; The above scheme settings, such as Figure 8-Figure 10 As shown, when the die-cutting blade 8 is swinging, a distance sensor 12 is provided to monitor the positioning height of the die-cutting blade 8. When the die-cutting blade 8 is too close to the working template 2, the electromagnet 1202 is controlled to start by signal transmission, so that the electromagnet 1202 drives the liquid push plate 1201 to move its position by magnetic effect, thereby increasing the internal volume of the through connection between the valve assembly 603 and the lateral hydraulic rod 6, and introducing the oil pressure in the middle section of the lateral hydraulic rod 6 into the enlarged cavity inside the through connection between the valve assembly 603 and the lateral hydraulic rod 6. In this process, the oil pressure in the middle section of the lateral hydraulic rod 6 achieves a pressure relief effect, and the die-cutting driving external force of the die-cutting blade 8 due to the swinging die-cutting controlled by the oil pressure is reduced, which can also facilitate the balance control of the die-cutting blade 8 while reducing the external impact force of the die-cutting blade 8.

[0026] Embodiment 2: Based on Embodiment 1, this technical solution is further Fig.11 and Fig.12 The hydraulic adjustment assembly 11 is disclosed as shown, including a positioned inner hollow cavity and an electric screw assembly 1101 rotatably mounted in the middle of the inner hollow cavity, and a liquid sealing plate 1102 is threadedly mounted on the outer side of the electric screw assembly 1101; wherein the liquid sealing plate 1102 and the inner hollow cavity are in sealed sliding connection, and a photoelectric sensor 1103 is correspondingly mounted on the bottom of the liquid sealing plate 1102 and the middle of the inner wall of the inner hollow cavity, and a transparent shell is disposed on the bottom of the liquid sealing plate 1102 and the inner wall of the inner hollow cavity outside the photoelectric sensor 1103; In the above scheme, the servo motor is used to control the forward and reverse rotation of the electric screw assembly 1101, so that the liquid sealing plate 1102 moves during the rotation. The pipeline is set to import and export the oil in the middle section of the left and right lateral hydraulic rods 6, thereby controlling the oil pressure in the middle section of the lateral hydraulic rod 6. The photoelectric sensor 1103 is used to facilitate the resetting of the liquid sealing plate 1102 after movement.

[0027] At the same time, the hydraulic adjustment component 11 can also be set up through the existing hydraulic valve and oil pressure injection component to achieve synchronous adjustment and control of the oil in the middle section of the left and right lateral hydraulic rods 6.
