Description

Technical Field

[0001] The present application relates to the field of die-cutting processing, and in particular to a die-cutting production line. Background Art

[0002] In existing die-cutting production lines, auxiliary rods are often installed above the circular die-cutting machine when die-cutting the workpiece strip. During die-cutting, the loading reel rotates so that the workpiece strip passes through the auxiliary rod and is then conveyed to the circular die-cutting machine. The circular die-cutting machine then die-cuts the workpiece strip, causing the die-cut workpiece to fall onto the conveyor belt below the workpiece strip. At the same time, the die-cut workpiece strip is wound up by the take-up reel. In actual applications, since each workpiece on the conveyor belt needs to maintain a certain distance, the distance between two adjacent die cavities formed after the workpiece strip is die-cut by the circular die-cutting machine is often large. When the size of the die-cut workpiece is smaller than the distance between two adjacent workpieces on the conveyor belt, the utilization rate of the workpiece strip is low, which in turn leads to higher die-cutting costs. Therefore, how to improve the utilization rate of the workpiece strip and reduce the die-cutting cost is a technical problem that needs to be solved urgently. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a die-cutting production line that fully die-cuts workpiece strips and reduces die-cutting costs.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] The die-cutting production line according to the first embodiment of the present application includes:

[0006] A feeding and winding mechanism, which is used to provide the workpiece material strip and to wind up the workpiece material strip after die-cutting;

[0007] A die-cutting circular knife component, which is used to die-cut the workpiece strip passing through;

[0008] Angle adjustment components, two of which are provided, both of which are provided above the die-cutting circular knife component, and the distance between the two angle adjustment components is adjustable; the two angle adjustment components are used to allow the workpiece material strip provided by the feeding and winding mechanism to pass through the die-cutting circular knife component and then return to the die-cutting circular knife component for secondary die-cutting and then be wound up by the feeding and winding mechanism.

[0009] The die-cutting production line according to the embodiment of the present application has at least the following beneficial effects: Due to the provision of two angle adjustment assemblies, the position at which the workpiece strip, after being discharged from the loading and reeling mechanism, passes through the two angle adjustment assemblies and returns to the die-cutting circular blade assembly is offset from the position at which the workpiece strip is conveyed to the die-cutting circular blade assembly by the loading and reeling mechanism. After the first die-cutting of the workpiece strip conveyed directly to the die-cutting circular blade assembly by the loading and reeling mechanism is completed, the spacing between two adjacent die cavities on this portion of the workpiece strip is a preset distance. As the loading and reeling mechanism rewinds, this portion of the workpiece strip passes through the two angle adjustment assemblies and returns to the die-cutting circular blade assembly, and the workpiece strip between two adjacent die cavities moves to the die-cutting position, allowing this portion of the strip to complete the second die-cutting. At this point, the two angle adjustment assemblies can shorten the spacing between two adjacent die cavities on the workpiece strip rewound by the loading and reeling mechanism, thereby increasing the utilization rate of the workpiece strip. Therefore, compared with the prior art, the present application solves the technical problem of how to improve the utilization rate of the workpiece strip and reduce the cost of die-cutting.

[0012] According to some embodiments of the present application, the horizontal swing angle range of the auxiliary rod relative to the base is 0 to 180°.

[0030] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0031] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0032] Figure 1 Schematic diagram of an embodiment of the die-cutting production line of the present application. Figure 1 As shown, the die-cutting production line of the embodiment of the present application includes a loading and reeling mechanism 300, a die-cutting circular knife component 200, and an angle adjustment assembly 100. The loading and reeling mechanism 300 is used to provide a workpiece material strip and reel the workpiece material strip after die-cutting. The die-cutting circular knife component 200 is used to die-cut the workpiece material strip passing through. Two angle adjustment assemblies 100 are provided. Both angle adjustment assemblies 100 are arranged above the die-cutting circular knife component 200. The spacing between the two angle adjustment assemblies 100 is adjustable. The two angle adjustment assemblies 100 are used to allow the workpiece material strip provided by the loading and reeling mechanism 300 to pass through the die-cutting circular knife component 200 and then return to the die-cutting circular knife machine 210 for secondary die-cutting before being reeled by the loading and reeling mechanism 300.

[0033] Since the above embodiment is provided with two angle adjustment components, there is a positional offset between the position where the workpiece material strip returns to the die-cutting circular knife component after being discharged from the feeding and winding mechanism through the two angle adjustment components and the material strip conveyed to the die-cutting circular knife component by the feeding and winding mechanism. After the first die-cutting of the workpiece material strip conveyed directly to the die-cutting circular knife component by the feeding and winding mechanism is completed, the spacing between two adjacent die cavities on this part of the workpiece material strip is a preset distance. As the feeding and winding mechanism is wound, this part of the workpiece material strip passes through the two angle adjustment components and returns to the circular knife die-cutting component, and the workpiece material strip between two adjacent die cavities will move to the die-cutting position so that this part of the material strip completes the second die-cutting. At this time, the two angle adjustment components can make the spacing between two adjacent die cavities on the workpiece material strip wound by the feeding and winding mechanism shorter. Therefore, the embodiment of the present application improves the utilization rate of the workpiece material strip and reduces the die-cutting cost.

[0034] The embodiment of the present application does not limit the spacing and the swing angle of the two angle adjustment components 100, and those skilled in the art can adjust them according to actual die-cutting requirements. In some embodiments, Figure 1 As shown, the angles of the two angle adjustment components 100 are adjusted so that they are closer to the middle. After the workpiece material strip undergoes the first die-cutting, it passes through the two angle adjustment components 100, causing the feeding direction of the workpiece material strip to deviate from the original straight line direction, and the position of the workpiece material strip is offset relative to the workpiece material strip conveyed to the die-cutting circular knife component 200 by the loading and rewinding mechanism 300. When the workpiece material strip passes through the die-cutting circular knife component 200 again, the die-cutting circular knife component 200 can die-cut the workpiece material strip between the die cavities produced by the first die-cutting. Therefore, compared to a single die-cutting process in which the workpiece material strip passes through an auxiliary rod whose angle cannot be adjusted, the workpiece material strip passes through two angle adjustment components 100 with a certain angle so that the feeding direction deviates from the straight line and undergoes two die-cutting processes. This can make the distance between two adjacent die cavities of the workpiece material strip smaller, reduce the amount of workpiece material strip used, improve the utilization rate of the workpiece material strip, and reduce the die-cutting cost.

[0035] It is understandable that the die-cutting production line also includes at least one die-cutting station, such as one of the die-cutting stations can be used for feeding and winding the conveyor belt, and another one of the die-cutting stations can die-cut the workpiece again after die-cutting on the workpiece belt, etc. In this regard, those skilled in the art can selectively set the die-cutting station according to actual needs, and the embodiments of the present application do not impose too many restrictions.

[0036] Figure 2 FIG. 1 is a schematic diagram of the structure of the angle adjustment assembly 100 of an embodiment of the die-cutting production line of the present application. It is understood that, referring to FIG. Figure 1 and Figure 2 As shown, the angle adjustment assembly 100 includes a base 110 and an auxiliary rod 120. One end of the auxiliary rod 120 is horizontally rotatably connected to the base 110. By adjusting the distance between the two auxiliary rods 120, the position of the workpiece strip returned to the circular die-cutting blade assembly 200 can be adjusted. The base 110 is disposed above the circular die-cutting blade assembly 200. By horizontally rotatably connecting one end of the auxiliary rod 120 to the base 110, the angle of the auxiliary rod 120 can be adjusted.

[0037] For example, Figure 2 As shown, the auxiliary rod 120 can be adjusted left and right after being connected to the base 110. The embodiment of the present application does not limit the rotation angle of the auxiliary rod 120. In some embodiments, the auxiliary rod 120 can rotate with the base 110 as the axis to a minimum of 0° and a maximum of 180°.

[0038] It is understandable that referring to Figure 2As shown, the base 110 is provided with a fixing screw hole 111, which is used to fix the base 110 above the die-cutting circular knife component 200 by screws. By providing the fixing screw hole 111, the base 110 can be screwed through the fixing screw hole 111 and fixed above the die-cutting circular knife component 200.

[0039] The embodiment of the present application does not limit the number of fixing screw holes 111, and those skilled in the art can selectively set them according to actual needs. For example, taking the setting of two fixing screw holes 111 as an example, Figure 2 As shown, the base 110 is symmetrically provided with two fixing screw holes 111 , and the base 110 is fixed above the circular die-cutting machine by passing two screws through the two fixing screw holes 111 .

[0040] It is understood that the horizontal swing angle range of the auxiliary rod 120 relative to the base 110 is 0-180 degrees. The auxiliary rod 120 can swing horizontally 0-180 degrees relative to the base 110, which can cause different degrees of deviation in the feeding direction of the workpiece strip passing through it.

[0041] It is understandable that referring to Figure 2 As shown, the base 110 is provided with two clamping blocks arranged in parallel with each other, and the two clamping blocks are spaced apart to form a clamping space. One end of the auxiliary rod 120 is disposed in the clamping space. Both clamping blocks are provided with a first connecting hole 112, and the two first connecting holes 112 are aligned. One end of the auxiliary rod 120 is provided with a second connecting hole 123 corresponding to the first connecting hole 112. By providing two clamping blocks and forming a clamping space between the clamping blocks, one end of the auxiliary rod 120 is embedded in the clamping space and can swing left and right.

[0042] For example, Figure 1 As shown, one end of the auxiliary rod 120 is embedded in the clamping space formed by the clamping block of the base 110 and adjusted to a certain angle. Then, a screw is used to pass through the first connecting hole 112 and the second connecting hole 123 to connect with the nut and tighten it to fix the auxiliary rod 120 and the base 110, so that the swing angle of the auxiliary rod 120 remains unchanged during the die-cutting process.

[0043] It is understandable that referring to Figure 2 As shown, the auxiliary rod 121 assembly includes an auxiliary rod 121 and a rotatable member 122. One end of the auxiliary rod 121 is connected to the rotatable member 122, and the rotatable member 122 is horizontally rotatably connected to the base 110. The auxiliary rod 121 is detachably connected to the rotatable member 122, and the rotatable member 122 is embedded in the base 110 and horizontally rotatably connected to the base 110, allowing the auxiliary rod 121 to swing left and right.

[0044] The embodiments of the present application do not limit the connection method of the auxiliary rod 121. For example, in some embodiments, one end of the auxiliary rod 121 is provided with an external thread, and the rotatable member 122 is provided with an internal threaded hole. One end of the auxiliary rod 121 can be threadedly connected to the rotatable member 122, making it easier to install the auxiliary rod 121 and the rotatable member 122. In other embodiments, one end of the auxiliary rod 121 can be directly welded to the rotatable member 122.

[0045] Figure 3 FIG. 1 is a structural diagram of a rotatable member 122 of an embodiment of a die-cutting production line of the present application. Figure 3 As shown, the rotatable member 122 includes a main body and a protrusion. The protrusion can be embedded in the base 110 and horizontally rotatably connected to the base 110. The main body is horizontally rotatably connected to the auxiliary rod 121. The rotatable member 122 is provided with a protrusion, which is embedded in the clamping space of the base 110 and rotatably connected to the base 110, so that the rotatable member 122 can rotate on the base 110.

[0046] It is understandable that referring to Figure 1 As shown, the circular die-cutting blade assembly 200 includes a circular die-cutting blade machine 210 and a plurality of positioning rods 220. The positioning rods 220 are located between the circular die-cutting blade machine 210 and the angle adjustment assembly 100. The positioning rods 220 are used to tighten the workpiece strip between the circular die-cutting blade machine 210 and the angle adjustment assembly 100. By providing the positioning rods 220 between the workpiece strip and the angle adjustment assembly 100, the workpiece strip between the circular die-cutting blade machine 210 and the angle adjustment assembly 100 is tightened, thereby fully flattening the workpiece strip. When the circular die-cutting blade machine 210 is die-cutting the workpiece strip, the workpiece strip can pass smoothly through the circular die-cutting blade machine 210, reducing the possibility of the workpiece strip being stuck.

[0047] The embodiment of the present application does not limit the number of positioning rods 220, and those skilled in the art can adjust it according to actual conditions. For example, one positioning rod 220 or two or more positioning rods are provided. The embodiment of the present application does not further limit the specific position of the positioning rod 220. For example, Figure 1 As shown, taking the setting of a positioning rod 220 as an example, a positioning rod 220 is set near the workpiece material strip outlet of the circular die cutting machine 210.

[0048] Refer to the following Figures 1 to 3 , describes the die-cutting process of one of the die-cutting stations in the die-cutting production line of the embodiment of the present application, as follows:

[0049] like Figure 1As shown, the feeding reel 301 rotates to convey the workpiece strip to the circular die-cutting machine 210, which then performs the first die-cut on the workpiece strip. After the first die-cut, the workpiece falls onto one side of the conveyor belt below the workpiece strip. After the first die-cut is completed, the strip passes through two auxiliary rods 121 and is rewound by the take-up reel, allowing the workpiece strip to be conveyed back to the circular die-cutting machine 210. The circular die-cutting machine 210 performs the second die-cut on the workpiece strip. At this point, the circular die-cutting machine will die-cut the portion of the strip between adjacent die cavities created after the first die-cut. After the second die-cut, the workpiece falls onto the conveyor belt below the workpiece strip, on the other side that is offset from the first die-cut. After the second die-cut is completed, the rewinding mechanism rewinds the waste strip. During the die-cutting process, there is a positional offset between the position where the workpiece strip returns to the circular die-cutting machine 210 after being discharged from the loading reel 301 and the position where the workpiece strip is transported from the loading reel 301 to the circular die-cutting machine 210. Therefore, when the circular die-cutting machine 210 performs a second die-cut on the workpiece strip, the die-cutting position is the portion between adjacent die cavities generated after the first die-cutting of the workpiece strip. Therefore, the distance between two adjacent die cavities on the workpiece strip is shorter. Therefore, the embodiment of the present application improves the utilization rate of the workpiece strip, thereby reducing the die-cutting cost.

[0050] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
