Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and more specifically, to an integrated die-cutting and waste removal device. Background Technology

[0002] The normal production of paper dinner plates involves printing, die-cutting, waste removal, forming, and packaging. Die-cutting and waste removal are essential steps. Currently, the process involves printing followed by die-cutting, then stacking the plates, followed by manual waste removal, re-stacking, and neat stacking. Currently, the die-cutting and waste removal processes are isolated, and waste removal relies entirely on manual labor, which is extremely demanding and physically exhausting, often resulting in untimely waste removal and accumulation of semi-finished products. Furthermore, after die-cutting, ejector pins are needed to lift the waste material to separate it from the finished product. Existing ejector pins are only located on the upper die to create a unidirectional force on the waste, resulting in a relatively long travel distance for the ejector pins during waste separation, affecting efficiency and indicating room for improvement. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides an integrated die-cutting and waste removal device, comprising a machine body, an upper die-cutting die and a lower die-cutting die disposed on the machine body, the upper die-cutting die being located above the lower die-cutting die and capable of moving closer to or away from the lower die-cutting die, both the upper die-cutting die and the lower die-cutting die being provided with multiple ejector pin assemblies, the ejector pin assemblies on the lower die-cutting die being adapted to apply a force to the waste material, and the ejector pin assemblies on the upper die-cutting die being adapted to apply a force to the die-cut product; the machine body is provided with a waste material conveyor belt and a product conveyor belt, the waste material conveyor belt being spaced above the product conveyor belt, the die-cut waste material being conveyed to the waste material conveyor belt, and the die-cut product being conveyed to the product conveyor belt.

[0004] Optionally, the machine body is provided with a waste material clamping and conveying assembly, which is adapted to clamp the die-cut waste material and convey it to the waste material conveyor belt.

[0005] Optionally, two sets of the waste material clamping and conveying components are provided at intervals and symmetrically, with the two sets of waste material clamping and conveying components located on both sides of the die-cutting lower die.

[0006] Optionally, the waste clamping and conveying assembly includes a support plate, a circulating conveyor belt, and a clamping cylinder. The support plate is located on one side of the die-cutting lower die and is fixedly installed on the machine body. The circulating conveyor belt is rotatably disposed on the side of the support plate near the die-cutting lower die. The clamping cylinder is installed on the circulating conveyor belt and moves synchronously with the circulating conveyor belt.

[0007] Optionally, the end of the circulating conveyor belt near the waste conveyor belt extends into the range of the waste conveyor belt.

[0008] Optionally, multiple clamping cylinders are provided circumferentially at intervals on the circulating conveyor belt.

[0009] Optionally, the die-cutting upper die includes an upper die base and an upper ejector plate. The upper die base is slidably mounted on the machine body. An ejector groove is provided on the top of the upper die base. The upper ejector plate is slidably mounted on the ejector groove and can be raised and lowered synchronously with the upper die base. The ejector assembly is mounted on the upper ejector plate.

[0010] Optionally, the ejector pin assembly includes an ejector pin rod, a threaded post, and a micro motor. The micro motor is connected to the threaded post and is adapted to drive the threaded post to rotate. The micro motor is fixedly installed on the upper ejector pin plate. One end of the ejector pin rod has a threaded groove. The threaded post is inserted into the threaded groove and threadedly connected to the ejector pin rod. The bottom of the ejector pin groove has an ejector pin hole through which the ejector pin rod passes. The outer wall of the ejector pin rod has a positioning strip. The wall of the ejector pin hole has a positioning groove for the positioning strip to be inserted.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] 1. By generating shearing force through bidirectional ejection, the ejector pin assemblies on both the upper and lower molds only need to move half of the previous distance, which improves the efficiency of waste separation.

[0013] 2. The die-cutting mechanism and the waste separation mechanism are both integrated on the machine body. The waste is automatically transported to the waste conveyor belt for collection through the waste clamping and conveying component. The whole process is relatively automated, which reduces the intensity of manual labor and improves the overall production efficiency.

[0014] 3. For materials of different thicknesses, the rotation of the micro motor can drive the extension and retraction of the ejector pin rod during waste separation, thus making it suitable for different application scenarios and improving the applicability of the ejector pin assembly.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-6 Specific embodiments of this utility model will be described in detail.

[0023] This utility model embodiment provides an integrated die-cutting and waste removal device, referring to... Figure 1 and Figure 2 The integrated die-cutting and waste removal device includes a body 1, an upper die-cutting die 2 and a lower die-cutting die 3 mounted on the body 1. The upper die-cutting die 2 is located above the lower die-cutting die 3 and can move closer to or away from the lower die-cutting die 3. Both the upper die-cutting die 2 and the lower die-cutting die 3 are equipped with multiple ejector pin assemblies 4. The ejector pin assemblies 4 on the lower die-cutting die 3 are suitable for applying force to the waste material, and the ejector pin assemblies 4 on the upper die-cutting die 2 are suitable for applying force to the die-cut product. In addition, the body 1 is equipped with a waste conveyor belt 11, a product conveyor belt 12, and a waste clamping and conveying assembly 13. The waste conveyor belt 11 is spaced above the product conveyor belt 12. The die-cut waste material is conveyed to the waste conveyor belt 11 by the waste clamping and conveying assembly 13, and the die-cut product is conveyed to the product conveyor belt 12.

[0024] One side of the machine body 1 is equipped with a raw material conveying device (not shown in the figure). The raw material conveying device is located on the side of the die-cutting lower die 3 away from the waste conveyor belt 11 and is suitable for conveying raw materials onto the die-cutting lower die 3. The die-cut products are pushed onto the product conveyor belt 12 by the conveyed raw materials.

[0025] Reference Figure 1 and Figure 2The die-cutting upper die 2 includes an upper die base and an upper ejector plate 21. An ejector groove is formed on the top of the upper die base, and a top cover is fitted and bolted to the groove opening. An upper drive cylinder 22 is fixedly installed on the top cover near the bottom of the ejector groove. The telescopic rod of the upper drive cylinder 22 is fixedly connected to the upper ejector plate 21, thereby driving the upper ejector plate 21 to slide up and down within the ejector groove. Multiple sets of ejector assemblies 4 on the die-cutting upper die 2 are all installed on the upper ejector plate 21 near the bottom of the ejector groove and arranged circumferentially. The multiple sets of ejector assemblies 4 have the same structure; the following description uses one set of ejector assemblies 4 as an example.

[0026] Combination Figure 2 Reference Figure 3 and Figure 4 The ejector assembly 4 includes an ejector rod 41, a threaded post 42, and a micro motor 43. The micro motor 43 is bolted to the upper ejector plate 21, and its motor shaft is connected to the threaded post 42 to drive its rotation. One end of the ejector rod 41 has a threaded groove, into which the threaded post 42 is inserted and threadedly connected. The bottom of the groove has an ejector hole for the ejector rod 41 to pass through. The outer wall of the ejector rod 41 has a positioning strip 44, and the wall of the ejector hole has a positioning groove for the positioning strip 44 to be inserted. When separating waste materials of different thicknesses, the micro motor 43 drives the threaded post 42 to rotate. The ejector rod 41, positioned by the positioning strip 44, is less likely to rotate synchronously with the threaded post 42, but instead will extend or retract relative to it. Furthermore, each micro motor 43 can be individually controlled, allowing different ejector rods 41 to extend or retract to different lengths, suitable for scenarios with varying raw material thicknesses, thus improving the applicability of the ejector assembly 4.

[0027] The top cover is equipped with a lifting cylinder 23. The telescopic rod of the lifting cylinder 23 is fixedly connected to the top cover. The cylinder body of the lifting cylinder 23 is fixed to the top of the machine body 1. Then, the upper mold base, ejector plate, and upper drive cylinder 22 will be lifted and lowered through the lifting cylinder 23 and cooperate with the lower die-cutting mold 3 to complete the die-cutting action.

[0028] Reference Figure 1 and Figure 5 The die-cutting lower die 3 includes a lower template 31, a lifting plate 32, and a lower drive cylinder 33. The lower template 31 is fixed to the machine body 1, the lifting plate 32 is located below the lower template 31, and the lower drive cylinder 33 is located below the lifting plate 32. The cylinder body of the lower drive cylinder 33 is fixed to the machine body 1, and the telescopic rod of the lower drive cylinder 33 is fixedly connected to the lifting plate 32 to drive the lifting plate 32 to rise and fall. The ejector pin assembly 4 on the die-cutting lower die 3 is located on the top of the lifting plate 32, and the lower template 31 has through holes for the corresponding ejector pin rod 41 to pass through and side grooves for the positioning strip 44 to be inserted.

[0029] Combination Figure 1 Reference Figure 5and Figure 6 Two sets of waste material clamping and conveying assemblies 13 are arranged symmetrically and at intervals. The two sets of waste material clamping and conveying assemblies 13 are located on both sides of the die-cutting lower die 3, which makes the movement of waste material more stable and prevents the waste material from colliding with the product and causing interference. The following description uses one set of waste material clamping and conveying assemblies 13 as an example.

[0030] The waste material clamping and conveying assembly 13 includes a support plate 14, a circulating conveyor belt 15, and a clamping cylinder 16. The circulating conveyor belt 15 is rotatably mounted on the support plate 14 near the die-cutting lower die 3. The support plate 14 is fixedly installed on the machine body 1, and the support plate 14 is equipped with a drive motor that drives the circulating conveyor belt 15 to rotate. The conveying direction of the circulating conveyor belt 15 is the same as the conveying direction of the waste material conveyor belt 11. The circulating conveyor belt 15 is a relatively thick and rigid conveyor belt. The clamping cylinder 16 is fixedly installed on the circulating conveyor belt 15 and moves synchronously with the circulating conveyor belt 15. After die-cutting is completed, the drive motor drives the circulating conveyor belt 15 to rotate so that the clamping cylinder 16 moves towards the waste material conveyor belt 11. During this process, the clamping cylinder 16 clamps the lifted waste material and conveys it onto the waste material conveyor belt 11. After the waste material is conveyed onto the waste material conveyor belt 11, the clamping cylinder 16 releases.

[0031] Multiple clamping cylinders 16 are arranged circumferentially on the circulating conveyor belt 15. When die-cutting, one of the clamping cylinders 16 clamps the previous waste material and conveys it to the waste material conveyor belt. At this time, the adjacent clamping cylinder 16 is located on the side of the die-cutting lower die 3 away from the waste material conveyor belt 11 and does not interfere with the die-cutting.

[0032] The end of the waste conveyor belt 11 near the die-cutting die 3 is located between and within the range of the two circulating conveyor belts 15. In this way, the clamping cylinder 16 can move the waste onto the waste conveyor belt 11 along with the circulating conveyor belts 15.

[0033] The implementation principle of the integrated die-cutting and waste removal device in this application embodiment is as follows: The ejector components on the upper die 2 and the lower die 3 can generate bidirectional shearing force through ejection. The ejector pin components 4 on both the upper and lower dies only need to move half the distance previously, improving the efficiency of waste separation. Furthermore, after die-cutting, the drive motor drives the circulating conveyor belt 15 to rotate, causing the clamping cylinder 16 to move towards the waste conveyor belt 11. During this process, the clamping cylinder 16 clamps the ejected waste and transports it to the waste conveyor belt 11. After the waste is transported to the waste conveyor belt 11, the clamping cylinder 16 releases, making the entire process relatively automated. When separating waste of different thicknesses, the micro motor 43 can drive the threaded column 42 to rotate. The ejector pin rod 41, positioned by the positioning strip 44, is not easily synchronized with the threaded column 42 but instead extends and retracts relative to the threaded column 42.

[0034] Similarly, the components included in the "components," "mechanisms," and "devices" of this disclosure can also be flexibly combined. They can be modularly produced according to actual needs and assembled as an independent module; or they can be assembled separately to form a module in this device.
