Description

Technical Field

[0001] This application relates to the field of die-cutting technology, specifically to a die-cutting apparatus. Background Technology

[0002] Currently, some plastic fasteners (or accessories made of other materials) have a symmetrical structure. After injection molding, the symmetrical injection molded parts are connected by a connecting frame. The connecting frame is the excess part formed when the injection mold pours material from the gate and simultaneously casts the two symmetrical injection molded parts. After injection molding, the connecting frame needs to be separated from the symmetrical injection molded parts. Currently, this connecting frame is cut off using a die-cutting machine to achieve the die-cutting and collection of the injection molded parts. The current problem is that after the injection molded parts are die-cut and collected, the symmetrical injection molded parts (corresponding to the left and right sides of the shoulder strap, thus two different structures) are mixed together, requiring manual sorting to separate the symmetrical injection molded parts, which is time-consuming and labor-intensive. Utility Model Content

[0003] In view of the above problems, this application provides a die-cutting device.

[0026] like Figure 1 As shown, the part to be processed 200 includes a connecting frame 220 and a first part 210 and a second part 230 connected to the connecting frame 220. The first part 210 and the second part 230 have different structures. The first part 210, the second part 230, and the connecting frame 220 are integrally formed by injection molding. After injection molding, the first part 210 and the second part 230 are separated from the connecting frame 220 by a punching mechanism 20. The first part 210 and the second part 230 have different structures, specifically they can be symmetrical structural parts or asymmetrical parts with different structures. Taking the part to be processed 200 as a shoulder buckle as an example, the connecting frame 220 has multiple first parts 210 arranged along the first direction X and the second direction Y, and multiple second parts 230 arranged along the first direction X and the second direction Y. In this configuration, multiple first accessories 210 and second accessories 230 are arranged alternately along the first direction X, meaning that a second accessory 230 is placed between two adjacent first accessories 210, and a first accessory 210 is placed between two second accessories 230. Similarly, multiple first accessories 210 and second accessories 230 are arranged alternately along the second direction Y, meaning that a second accessory 230 is placed between two adjacent first accessories 210, and a first accessory 210 is placed between two second accessories 230. The first accessories 210 and second accessories 230 have a symmetrical structure. For example, on a backpack, the left and right shoulder buckles are roughly symmetrical, but their structures are different, requiring separate placement of the left and right shoulder buckles.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, according to an embodiment of this application, a die-cutting apparatus 100 is provided for die-cutting and dispensing a workpiece 200 to be processed. The die-cutting apparatus 100 includes a dispensing mechanism 10, a die-cutting mechanism 20 and a driving mechanism 30.

[0028] The material distribution mechanism 10 includes a support plate 11, a first guide plate 12, and a second guide plate 13. The support plate 11 is configured to hold the parts to be processed 200. The support plate 11 has a first guide port 112 and a second guide port 113 spaced apart from each other. The first guide port 112 and the second guide port 113 are respectively configured to output the first part 210 and the second part 230 in a one-to-one correspondence. The first guide port 112 is connected to the first guide plate 12, and the second guide port 113 is connected to the second guide plate 13. The drive mechanism 30 is capable of driving the punching mechanism 20. The drive mechanism 30 drives the punching mechanism 20 to move to separate the first part 210 and the second part 230 from the connecting frame 220. The separated first part 210 and the second part 230 fall onto the first guide plate 12 and the second guide plate 13 through the first guide port 112 and the second guide port 113, respectively.

[0029] In one example, multiple first accessories 210 connected to the connecting frame 220 and arranged along the first direction X and the second direction Y each correspond to a first guide port 112, and multiple second accessories 230 connected to the connecting frame 220 and arranged along the first direction X and the second direction Y each correspond to a second guide port 113. The specific positions of the first guide ports 112 and the second guide ports 113 can be determined based on the first accessories 210 and the second accessories 230 on the connecting frame 220.

[0030] The number of first feed inlets 112 and second feed inlets 113 can both be one or more.

[0031] The drive mechanism 30 can be, but is not limited to, linear drive components such as cylinders or electric push rods.

[0032] The support plate 11 has a support surface 111 on the side facing the punching mechanism 20. The support surface 111 is provided with a first guide port 112 and a second guide port 113. The first guide port 112 and the second guide port 113 respectively penetrate the support plate 11 along the thickness direction of the support plate 11.

[0033] Both the first guide plate 12 and the second guide plate 13 can be flat plates or bent plates.

[0034] The first guide plate 12 and the second guide plate 13 can be set horizontally or at an angle. When the first guide plate 12 and the second guide plate 13 are set horizontally, the material can be picked up manually.

[0035] The first guide port 112 can be connected to the first guide plate 12 through a pipeline, or the first guide plate 12 can be directly set below the first guide port 112, and the first accessory 210 falls directly from the first guide port 112 to the first guide plate 12.

[0036] The second guide port 113 can be connected to the second guide plate 13 through a pipeline, or the second guide plate 13 can be directly set below the second guide port 113, and the second accessory 230 falls directly from the second guide port 113 to the second guide plate 13.

[0037] In one example, the first discharge port 122 of the first guide plate 12 is provided with two first arc-shaped retaining edges 123.

[0038] In one example, the second discharge port 132 of the second guide plate 13 is provided with two second arc-shaped baffles 133, and the second arc-shaped baffles 133 on both sides of the second guide plate 13 form the second discharge port 132 at one end of the second guide plate 13.

[0039] The first discharge port 122 and the second discharge port 132 can be respectively arranged on opposite sides or adjacent sides of the material distribution mechanism 10 along the horizontal direction.

[0040] The driving mechanism 30 drives the punching mechanism 20 to punch the first part 210 and the second part 230 off the connecting frame 220. The first part 210 is discharged through the first guide port 112 and the first guide plate 12, and the second part 230 is discharged through the second guide port 113 and the second guide plate 13. This achieves the classification and collection of the first part 210 and the second part 230 with different structures. Compared with the prior art, it can avoid the first part 210 and the second part 230 from being mixed together, thus saving the trouble of manual sorting and saving time and effort.

[0041] In some implementations, such as Figure 3 and Figure 5 As shown, the die-cutting device 100 has a height direction Z. The first guide plate 12 and the second guide plate 13 are spaced apart in the height direction Z. The second guide plate 13 is located above the first guide plate 12. The die-cutting device 100 also has a guide tube 14 with open ends. The guide tube 14 passes through the second guide plate 13. The first end of the guide tube 14 is connected to the first guide port 112. The second end of the guide tube 14 is spaced apart from the first guide plate 12 and located above the first guide plate 12. The first accessory 210 is conveyed to the first guide plate 12 via the guide tube 14.

[0042] The height direction Z refers to the reference direction of the die-cutting device 100 in its working or naturally placed state.

[0043] The feed tube 14 can be, but is not limited to, a square tube or a round tube.

[0044] In one example, such as Figure 3 As shown, the material distribution mechanism 10 also includes a base plate 15 and a connecting column 16. The base plate 15 is connected to the support plate 11 through the connecting column 16. Both the first guide plate 12 and the second guide plate 13 are provided with clearance holes 17 to facilitate the passage of the connecting column 16. Along the height direction Z of the material distribution mechanism 10, the guide tube 14 is provided with a through hole 18 at the projection position of the second guide plate 13 so that the guide tube 14 can pass through the through hole 18.

[0045] The length direction of the feed tube 14 can be the same as the height direction Z, or it can be inclined relative to the height direction Z.

[0046] Both the first guide plate 12 and the second guide plate 13 can be fixed to the side plate 19 connected to the base plate 15, specifically by means of screws, riveting or welding.

[0047] After the punching mechanism 20 punches the first part 210 and the second part 230, the first part 210 falls into the first guide plate 12 through the guide pipe 14 to collect the first part 210. The first part 210 and the second part 230 are discharged from different guide ports, which can avoid the first part 210 and the second part 230 from being mixed together and avoid the trouble of manual sorting. In some implementations, such as Figure 3 , Figure 7 and Figure 8 As shown, there are multiple first guide ports 112 and multiple second guide ports 113, and multiple guide tubes 14 are provided. Each first guide port 112 is connected to a guide tube 14. The multiple guide tubes 14 are spaced apart and have gaps W. The second guide port 113 is connected to the gaps W. The separated second accessory 230 falls to the second guide plate 13 through the gaps W.

[0048] The gap W can be designed according to the maximum size of the second accessory 230, so that the maximum size of the second accessory 230 can pass through it.

[0049] The second part 230 falls from the second guide port 113 and directly onto the second guide plate 13 through the gap W. There is no need to set up additional components to guide the second part 230 between the second guide port 113 and the second guide plate 13. This makes the structure simple and compact, and reduces the probability of the second part 230 getting stuck due to additional guiding components between the second guide port 113 and the second guide plate 13, thereby improving the reliability of the die-cutting device 100.

[0050] In some implementations, such as Figure 3 and Figure 6 As shown, the guide tube 14 is located at the bottom of the support plate 11. The guide tube 14 includes a tube body 141 and a connecting part 142. The tube body 141 has the aforementioned first end and second end, both of which are open structures. The connecting part 142 is located outside the tube body 141 and connected to the first end of the tube body 141. The connecting part 142 is detachably connected to the support plate 11. The second end of the tube body 141 is spaced apart from the first guide plate 12 and located above the first guide plate 12.

[0051] In one example, the connecting portion 142 can be connected to the support plate 11 via a fastener. Specifically, the connecting portion 142 has a first connecting hole 1421, and the support plate 11 has a second connecting hole 115 on the side facing the connecting portion 142. The end of the fastener passes through the first connecting hole 1421 and is threadedly connected to the second connecting hole 115. The fastener can be a screw or a combination of a stud and a nut. In other examples, the connection between the connecting portion 142 and the support plate 11 can be a snap-fit ​​connection.

[0052] The connecting part 142 is detachably connected to the support plate 11, which facilitates the disassembly and assembly of the guide tube 14, so as to facilitate the maintenance and replacement of the die-cutting device 100.

[0053] In some implementations, such as Figure 2 , Figure 3 and Figure 5 As shown, the die-cutting device 100 has a height direction Z. The first guide plate 12 and the second guide plate 13 are spaced apart in the height direction Z. The first guide plate 12 has a first receiving surface 121 and a first discharge port 122. The first receiving surface 121 is configured to receive the first part 210 discharged from the first guide port 112 and discharge it from the first discharge port 122. The second guide plate 13 has a second receiving surface 131 and a second discharge port 132. The second receiving surface 131 is configured to receive the second part 230 discharged from the second guide port 113 and discharge it from the second discharge port 132. The first discharge port 122 and the second discharge port 132 are respectively located on different sides of the material distribution mechanism 10 in the first direction X. The first direction X intersects with the height direction Z of the material distribution mechanism 10.

[0054] In order to enable the first component 210 and the second component 230 to slide smoothly from the first receiving surface 121 and the second receiving surface 131 respectively, the surfaces of the first receiving surface 121 and the second receiving surface 131 can be made smooth to reduce the resistance to sliding.

[0055] Both the first receiving surface 121 and the second receiving surface 131 can be a plane, a concave curved surface, or a convex curved surface.

[0056] A receiving tool 40 can be provided at the first discharge port 122 and the second discharge port 132 respectively. The discharge sides of the first receiving surface 121 and the second receiving surface 131 are different sides of the material distribution mechanism 10 along the first direction X. Compared with the first receiving surface 121 and the second receiving surface 131 being set on the same side of the material distribution mechanism 10, the first accessory 210 and the second accessory 230 of different specifications are discharged from the first discharge port 122 and the second discharge port 132 respectively, avoiding material mixing during receiving, avoiding the trouble of manual sorting, and enabling the receiving tool 40 to have sufficient receiving space.

[0057] In some implementations, such as Figure 7 As shown, the first receiving surface 121 and the second receiving surface 131 are both inclined relative to the support plate 11, and the first receiving surface 121 and the second receiving surface 131 have an included angle α, where the angle α ranges from 5° to 85°.

[0058] This creates receiving spaces of different sizes between the first receiving surface 121 and the second receiving surface 131 to accommodate the first component 210 and the second component 230 of different volumes. The first component 210 falls into the receiving space from the first guide port 112 and from the first receiving surface 121 to the first discharge port 122, while the second component 230 falls into the receiving space from the second guide port 113 and from the second receiving surface 131 to the second discharge port 132.

[0059] In some implementations, such as Figure 3 and Figure 4 As shown, the punching mechanism 20 includes a connecting seat 21 and a breaking member 22. The connecting seat 21 is driven and connected to the driving mechanism 30. The breaking member 22 is located at the bottom of the connecting seat 21 and connected to it. A breaking member 22 corresponds to each of the first guide port 112 and the second guide port 113. The die-cutting device 100 has a height direction Z. The breaking member 22 is configured to move along the height direction Z under the drive of the driving mechanism 30 and break the connecting frame 220. The breaking member 22 has a breaking inclined surface 221. When the first component 210 and the second component 230 are about to break with the connecting frame 220, or at the moment of breaking, the contact area between the breaking member 22 and the first component 210 and the second component 230 is maximized to prevent the first component 210 and the second component 230 from splashing during the breaking process.

[0060] The connection between the drive end of the drive mechanism 30 and the connecting seat 21 can be a screw connection, welding, or bolt connection, etc.

[0061] In one example, the die-cutting device 100 further includes a support 50, and a connecting seat 21 is slidably connected to the support 50 along the height direction Z. Specifically, the support 50 is equipped with a guide rail 51, and a slider 52 is slidably connected to the guide rail 51. The slider 52 and the connecting seat 21 can be fixed with screws. A drive mechanism 30 is mounted on the support 50, and the drive end of the drive mechanism 30 is connected to the connecting seat 21 with screws. For example, the drive mechanism 30 is a cylinder.

[0062] During the punching process, the pressure-breaking bevel 221 can gradually increase the pressing area during the downward pressing process to prevent the first component 210 and the second component 230 from splashing due to sudden stress changes at the connection positions between them and the connecting member 220. This allows the first component 210 and the second component 230 to be discharged from their respective guide ports, reducing the possibility of material mixing. In other examples, the pressure-breaking member 22 can also be directly driven by the drive mechanism 30. Each pressure-breaking member 22 is driven by a drive mechanism 30, and each pressure-breaking member 22 is driven individually by a drive mechanism 30 to achieve punching.

[0063] In some embodiments, when the punching mechanism 20 moves toward the material distribution mechanism 10 to its maximum stroke, a portion of the breaking member 22 corresponding to the first guide port 112 is located inside the first guide port 112, and a portion of the breaking member 22 corresponding to the second guide port 113 is located inside the second guide port 113, thereby separating the first accessory 210 and the second accessory 230 from the connecting frame 220.

[0064] Compared with the method of cutting the connecting frame 220 connected to the first accessory 210 and the second accessory 230 respectively on the support surface 111 by the punching mechanism 20, the possibility of the support surface 111 being crushed can be reduced. Moreover, the punching mechanism 20 has a large stroke, which can reduce the possibility that the connection position between the first accessory 210 and the second accessory 230 and the connecting frame 220 cannot be completely cut off, which is beneficial to improving the reliability of the molding punching device 100.

[0065] In some implementations, such as Figure 3 and Figure 4 As shown, the punching mechanism 20 also includes a pre-pressing mechanism 23, which includes a pre-pressing rod 231 and an elastic element 232. The pre-pressing rod 231 is slidably connected to the connecting seat 21 along the height direction Z of the material distribution mechanism 10 and is configured to press the connecting frame 220 against the support plate 11. One end of the elastic element 232 abuts against the pre-pressing rod 231, and the other end of the elastic element 232 abuts against the connecting seat 21. The elastic element 232 is configured to cause the pre-pressing rod 231 to tend to move towards the material distribution mechanism 10.

[0066] When the preload rod 231 is not pressed, the distance from the bottom of the preload rod 231 to the top of the connecting seat 21 along the height direction Z is greater than the distance from the compression member 22 to the top of the connecting seat 21.

[0067] The elastic element 232 can be a spring or an elastic plate, etc.

[0068] For example, the elastic element 232 can be a compression spring, which is sleeved on the preload rod 231 and located at the bottom of the connecting seat 21. In its natural state (when the preload rod 231 is not in contact with the connecting frame 220), the preload rod 231 is in an extended state under the elastic force of the compression spring. The compression spring can be replaced by multiple elastic plates. The elastic plates can be elastic plates with one concave side and the other bulging side, with a hole in the center of the elastic plate. The preload rod 231 passes through the hole of the elastic plate, and the multiple elastic plates are located below the connecting seat 21.

[0069] The connecting seat 21 is provided with a guide hole 211 that slides with the preload rod 231. In order to prevent the preload rod 231 from disengaging from the connecting seat 21 under the action of the elastic member 232, a limiting part 2311 is provided at the top of the preload rod 231. In the natural state of the preload rod 231, the limiting part 2311 abuts against the connecting seat 21.

[0070] Multiple preload rods 231 can be set to simultaneously press down on multiple different positions of the same connecting frame 220. Alternatively, multiple parts to be processed 200 can be placed on top of the material distribution mechanism 10 and fixed by the preload rods 231. Multiple cutting elements 22 are used to punch the multiple parts to be processed 200, thereby improving punching efficiency.

[0071] During the downward movement of the punching mechanism 20, before the breaking member 22 touches the connecting frame 220 connected to the first accessory 210 and the second accessory 230, the bottom of the pre-compression rod 231 first contacts the connecting frame 220. As the punching mechanism 20 moves downward, the breaking member 22 then abuts against the connecting frame 220. This allows the pre-compression rod 231 to pre-fix the connecting frame 220, preventing displacement of the connecting frame 220 during the cutting process and ensuring the reliability of the cutting. In addition, the pre-compression of the pre-compression rod 231 can also reduce the possibility that the first accessory 210 and the second accessory 230 will be bounced out of the first guide port 112 or the second guide port 113 due to the elastic deformation of the connecting frame 220 after cutting, reducing the probability of material mixing and improving the reliability of material distribution.

[0072] In some implementations, such as Figure 8 and Figure 9As shown, the support plate 11 has a support surface 111, and the support surface 111 is provided with a first positioning groove 1141 and a second positioning groove 1142. The first positioning groove 1141 extends along the first direction X, and the second positioning groove 1142 extends along the second direction Y. The first positioning groove 1141 and the second positioning groove 1142 are used to accommodate the connecting frame 220 and position the connecting frame 220. The first direction X, the second direction Y and the height direction Z of the material distribution mechanism 10 are perpendicular to each other.

[0073] The cross-sectional shape of both the first positioning groove 1141 and the second positioning groove 1142 can be, but is not limited to, a semi-circular arc, a rectangle, a V-shape, or a trapezoid.

[0074] Therefore, before the breakage, the first positioning groove 1141 and the second positioning groove 1142 can position the connecting frame 220 along the first direction X and the second direction Y to improve the accuracy of the breakage position.
