Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, and in particular to a pin-type blanking structure for a flatbed die cutter. Background Technology

[0002] In modern industrial production, die-cutting machines, as key equipment widely used in material processing, play an indispensable role in many manufacturing industries. The processing of materials using die-cutting machines involves precision operations such as die-cutting and trimming of various materials (e.g., paper, plastic film, thin metal sheets). After these materials are precisely cut by the die-cutting blades, waste of varying shapes and sizes is generated. The existence of this waste is a crucial aspect of the entire production process that requires proper handling, as effective waste management is essential for ensuring production efficiency and product quality. From a production efficiency perspective, if waste is not handled promptly and effectively, it will accumulate in the processing area. For highly automated die-cutting machine production lines, even a small amount of accumulated waste can disrupt the normal material transport path.

[0003] The existing structure has the following problems when in use: 1. The traditional method of manually cleaning waste is inefficient and prone to oversight, resulting in waste residue and affecting product quality; while the collection tank design of the simple mechanical cleaning method is not perfect, and the waste generated from the processing of multi-hole products is not completely collected; 2. The existing ejector device cannot flexibly adjust the number and layout of ejector pins according to the number and shape of the product holes, and cannot meet the processing needs of different products (such as single-hole and multi-hole products), resulting in poor waste ejection effect; 3. The ejector pin angle is fixed and cannot be adjusted slightly according to the actual processing situation, which limits the applicability of the ejector device to different products and affects the waste separation efficiency. Therefore, a flat-blade machine ejector pin-type material discharge structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pin-type blanking structure for a flat-blade machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flat-blade machine ejector pin-type blanking structure, including a worktable, a lower template installed at the center of the top of the worktable, guide support rods fastened to both sides of the top of the worktable near the lower template, a limit lifting plate installed at the top of the guide support rods, an upper template installed at the bottom of the limit lifting plate, a pressing structure installed at the top of the limit lifting plate, the pressing structure being controlled by a cylinder, a first mounting bracket fastened to one side of the limit lifting plate, a sliding groove opened on the outer side of one side of the guide support rod, and a second mounting bracket slidably connected within the sliding groove of the guide support rod.

[0006] Preferably, a discharge platform is installed on the top of the workbench near the guide support rod, and the top of the discharge platform is provided with a slot.

[0007] Preferably, a vacuum cleaner is placed at the bottom of the workbench, and a vacuum cleaner head is connected to the top of the vacuum cleaner head, with the top of the vacuum cleaner head connected to the bottom of the slot.

[0008] Preferably, a central conveyor is installed on the bottom of the workbench near the discharge platform, and a bottom conveyor is installed on one side of the workbench.

[0009] Preferably, the first mounting bracket and the second mounting bracket have the same structure. Both sides of the first mounting bracket and the second mounting bracket are fitted with connecting collars. Both sides of the first mounting bracket and the second mounting bracket are engaged with connecting rods. The front of each connecting rod is provided with a bolt hole.

[0010] Preferably, a mounting block is sleeved on the outside of the connecting rod, and a fixing bolt passes through the mounting block and the connecting rod. The fixing bolt and the bolt hole are mutually compatible, and a connecting post connects the mounting blocks on the first mounting frame and the second mounting frame.

[0011] Preferably, an adjuster is snapped into the bottom of the connecting column, and a ring is embedded inside the adjuster. The ring is semi-circular, and an adjusting head is installed inside the ring. A drive motor is installed on the front of the adjusting head, and a pin is threaded to the bottom of the adjusting head.

[0012] Beneficial effects

[0013] In this invention, the ejector-pin type feeding structure of the flatbed cutting machine has a significant effect on improving production efficiency. Through a rationally designed conveying system, including a discharge platform, a middle conveyor, and a bottom conveyor, materials can be continuously, stably, and efficiently conveyed forward, reducing time wastage caused by poor conveying. Furthermore, the automated ejector-pin feeding design, combined with a dust collector to collect waste, avoids the tedious process of manual waste removal and the increased downtime due to human error. Throughout the process, waste is promptly handled, preventing accumulation in the processing area and ensuring stable operation of the flatbed cutting machine for extended periods. This greatly increases the product output per unit time, effectively improving overall production efficiency.

[0014] In this invention, the ejector pin-type blanking structure of the flatbed die-cutting machine significantly improves product quality. The ejector pin device can be flexibly adjusted according to the specific multi-hole structure of the product, accurately adapting to both single-pin and multi-pin (row) structures. Furthermore, the ejector pins can swing slightly left and right to adjust their angle, ensuring that waste material is precisely ejected during die-cutting, preventing waste residue from scratching, contaminating the product, or affecting the bonding effect between multiple layers of material. Simultaneously, the cuttable release film design on the discharge platform further ensures effective separation of waste material from the product, preventing waste from re-mixing into the product, effectively guaranteeing the surface quality and overall performance of the product, significantly reducing the defect rate, and improving product quality.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-6 A flat-blade cutting machine ejector pin-type blanking structure includes a worktable 1. A lower template 11 is installed at the center of the top of the worktable 1. Guide support rods 7 are engaged on both sides of the top of the worktable 1 near the lower template 11. A limit lifting plate 2 is installed on the top of the guide support rod 7. An upper template 12 is installed at the bottom of the limit lifting plate 2. A pressing structure 10 is installed on the top of the limit lifting plate 2. The pressing structure 10 is controlled by a cylinder. A first mounting bracket 3 is engaged on one side of the limit lifting plate 2. A sliding groove 8 is opened on the outer side of one guide support rod 7. A second mounting bracket 4 is slidably connected in the sliding groove 8 of the guide support rod 7.

[0027] During operation, the material passes between the upper template 12 and the lower template 11, through the discharge platform 9, the middle conveyor 5, and the bottom conveyor 6. The material is continuously conveyed forward. The pressing structure 10 can drive the limit lifting plate 2 and the bottom upper template 12 to rise and fall. When the limit lifting plate 2 descends, the first mounting frame 3 on one side will also descend. At the same time, because the first mounting frame 3 and the second mounting frame 4 are assembled together, the second mounting frame 4 at the bottom will also descend when the first mounting frame 3 descends.

[0028] A discharge platform 9 is installed on the top of the workbench 1 near the guide support rod 7, and a slot 15 is opened on the top of the discharge platform 9.

[0029] A vacuum cleaner 14 is placed at the bottom of the workbench 1. A vacuum cleaner head 13 is connected to the top of the vacuum cleaner 14. The top of the vacuum cleaner head 13 is connected to the bottom of the slot 15.

[0030] A central conveyor 5 is installed on the bottom of the workbench 1 near the discharge platform 9, and a bottom conveyor 6 is installed on one side of the workbench 1.

[0031] The first mounting bracket 3 and the second mounting bracket 4 have the same structure. Both sides of the first mounting bracket 3 and the second mounting bracket 4 are fitted with connecting collars 21. Both sides of the first mounting bracket 3 and the second mounting bracket 4 are fitted with connecting rods 20. Both sides of the connecting collars 21 are fitted with bolt holes 22.

[0032] The connecting rod 20 is provided with multiple bolt holes 22, and each bolt hole 22 can be used to install a set of mounting blocks 16.

[0033] A mounting block 16 is sleeved on the outside of the connecting rod 20. A fixing bolt 23 passes through the mounting block 16 and the connecting rod 20. The fixing bolt 23 and the bolt hole 22 are compatible with each other. A connecting post 17 connects the mounting blocks 16 on the first mounting bracket 3 and the second mounting bracket 4.

[0034] An adjuster 18 is snapped into the bottom of the connecting post 17. An ring 24 is embedded inside the adjuster 18. The ring 24 is a semi-circular ring. An adjusting head 25 is installed inside the ring 24. A drive motor 19 is installed on the front of the adjusting head 25. A pin 26 is threadedly connected to the bottom of the adjusting head 25.

[0035] like Figure 4 and Figure 5 As shown, Figure 4 To install a set of ejector pins 26, Figure 5 Multiple sets of ejector pins 26 are installed in a row, and the ejector pins 26 at the bottom of the adjuster 18 can swing left and right slightly to adjust the angle. Specific Implementation Example 2:

[0037] Reference Figure 1-6 The following is the working principle of the entire device:

[0038] I. Structural Setup and Initial State

[0039] Workbench and template installation:

[0040] The workbench 1 serves as the basic support platform for the entire structure, with the lower template 11 securely installed at its top center, providing a reference surface for subsequent material processing. Simultaneously, guide struts 7 are precisely engaged on both sides of the top of the workbench 1 near the lower template 11, ensuring its verticality and stability and strictly limiting the movement path of the limiting lifting plate 2.

[0041] The lifting structure is associated with the formwork:

[0042] The upper template 12 is firmly installed at the bottom of the limiting lifting plate 2, and the two form an integral motion unit. The pressing structure 10 at the top of the limiting lifting plate 2 is driven by a cylinder. The cylinder serves as a power source, providing precise and controllable force to the pressing structure 10. In the initial state, when the pressing structure 10 is not activated, the upper template 12 and the limiting lifting plate 2 are at a specific initial height, waiting for processing instructions.

[0043] Mounting bracket and guide structure fit together:

[0044] One side of the limiting lifting plate 2 is snapped into the first mounting bracket 3, and the two are tightly connected to ensure the synchronization of movement. A carefully designed sliding groove 8 on the outer side of the guide support rod 7 slides in conjunction with the second mounting bracket 4. This design allows the second mounting bracket 4 to slide smoothly within the groove 8 while restricting its freedom in other directions, ensuring the stability of the entire motion system. The first mounting bracket 3 and the second mounting bracket 4 have identical structures and are interconnected. Connecting collars 21 are fitted onto both sides of each bracket, and connecting rods 20 are snapped between the connecting collars 21. Bolt holes 22 on the connecting rods 20 are evenly distributed at specific intervals for mounting blocks 16. The mounting blocks 16 are fixed to the connecting rods 20 by the tight fit of fixing bolts 23 with the bolt holes 22, ensuring that they will not loosen during operation. A connecting column 17 connects the mounting blocks 16 on the first mounting bracket 3 and the second mounting bracket 4. The bottom of the connecting column 17 is firmly snapped into the adjuster 18, forming a stable force transmission link.

[0045] II. Orderly Process of Material Transfer

[0046] Materials enter the processing area:

[0047] After the work is started, the material is accurately conveyed from the external conveying device to the processing area between the upper template 12 and the lower template 11. At this time, the lower template 11 provides a stable support plane for the material, ensuring that the material is in the correct position and posture before processing, and also provides reaction force support for subsequent die-cutting processing.

[0048] Transition of the discharge platform:

[0049] After processing between the upper template 12 and the lower template 11, the material is transferred to the discharge platform 9. The discharge platform 9 is located on the top of the workbench 1, near the guide support rod 7, and its top slot 15 has a special design consideration. The shape, size, and position of the slot 15 are carefully designed according to the waste processing flow and material characteristics. Its basin-like shape facilitates the centralized collection and guidance of waste. The release film covering the discharge platform 9 can be precisely cut according to the size of the product holes. This not only effectively prevents the material from sliding or shifting on the discharge platform 9, but also ensures that the waste smoothly separates from the product after passing through the release film and enters the slot 15.

[0050] Middle and bottom conveyors relay:

[0051] The material exiting from the discharge platform 9 is smoothly received by the central conveyor 5, which is installed at the bottom of the worktable 1 and close to the discharge platform 9. Through precisely designed conveying speed and friction, it ensures that the material will not jam or deform during transport. After a brief stay on the central conveyor 5, the material continues to be conveyed to the bottom conveyor 6, which is installed on one side of the worktable 1. The bottom conveyor 6 has sufficient conveying capacity and stability to deliver the processed material out of the flatbed cutter, completing the entire material conveying process and ensuring a continuous, stable, and orderly flow of material throughout the entire processing.

[0052] III. Working principle and waste disposal details of the ejector pin

[0053] The downward pressure drives the ejector pin to move:

[0054] When the flatbed cutting machine begins processing, the downward pressing structure 10 is activated by the cylinder, applying downward pressure to the limiting lifting plate 2. Due to the transmission of force, the limiting lifting plate 2 causes the upper template 12 to begin to descend, and simultaneously, the first mounting bracket 3 connected to it also descends synchronously. Due to the assembly relationship between the first mounting bracket 3 and the second mounting bracket 4, the second mounting bracket 4 slides downward along a predetermined path within the groove 8 of the guide support rod 7. This linkage mechanism ensures the synchronization of the movement of the entire mounting bracket system (including the first mounting bracket 3, the second mounting bracket 4, and all components connected to them) with the upper template 12.

[0055] Ejector action and waste separation:

[0056] As the first mounting bracket 3 and the second mounting bracket 4 descend, the adjuster 18 connected via the connecting column 17 also descends. The internal structural design of the adjuster 18 is crucial for the precise control of the ejector pin 26. A semi-circular ring 24 is embedded inside the adjuster 18, and an adjusting head 25 is installed within the ring 24. A drive motor 19 mounted on the front of the adjusting head 25 provides power for the angle adjustment of the ejector pin 26. During descent, the ejector pin 26 contacts the material processing area. When the ejector pin 26 moves upward, its top makes close contact with the material. Through the precisely designed shape and height of the ejector pin, waste generated during material processing can be accurately separated from the product. Depending on the different product requirements, the number and layout of the ejector pins 26 can be flexibly adjusted by selecting appropriate bolt holes 22 on the connecting rod 20 to install mounting blocks 16, thereby achieving a single ejector pin or multi-ejector pin (row) structure, ensuring adaptability to different porous products.

[0057] Waste collection process:

[0058] After being ejected by the ejector pin 26, the waste material falls naturally due to gravity, passing through the slot 15 on the discharge platform 9. At this time, the vacuum cleaner 14 placed at the bottom of the workbench 1 begins to function. The suction pipe head 13 connected to the top of the vacuum cleaner 14 is tightly connected to the bottom of the slot 15, forming an efficient waste collection channel. The vacuum cleaner 14 uses its powerful suction to quickly suck up the waste material falling through the slot 15, preventing waste from accumulating in the workbench 1, thus keeping the work area clean and preventing waste from interfering with equipment operation. For example, it prevents waste from entering the conveying mechanism and affecting the smoothness of material conveying, or prevents waste from entering other moving parts and causing wear or malfunction, ensuring the stability and efficiency of the entire production process.

[0059] IV. Precise Adjustment Mechanism of the Ejector Device

[0060] Adjustment of the number and position of ejector pins:

[0061] The layout adjustment of the ejector pin 26 is mainly achieved by installing different numbers of mounting blocks 16 in the bolt holes 22 on the connecting rod 20. Each bolt hole 22 provides an installation position option, allowing the operator to select the appropriate bolt hole 22 to install the mounting block 16 based on the specific multi-hole configuration of the product. The number and position of the mounting blocks 16 determine the distribution of the connecting posts 17, thus affecting the layout of the ejector pin 26. This flexible adjustment method allows the ejector pin 26 to accurately align with the scrap area on the product, improving the efficiency and accuracy of scrap ejection.

[0062] Adjustment of ejector pin angle and plane position:

[0063] The adjusting head 25 inside the adjuster 18 can rotate precisely under the drive of the drive motor 19. Since the bottom of the adjusting head 25 is threadedly connected to the ejector pin 26, the ejector pin 26 can swing slightly left and right to adjust its angle when the adjusting head 25 rotates. Simultaneously, the entire guide rod support (including the first mounting bracket 3, the second mounting bracket 4, and other related components) is fixedly connected to the upper template of the flatbed cutting machine and moves with the upper template. During this process, the ejector pin device on the intermediate guide rod can move within a certain range in the X and Y axes. This movement function is achieved through a special connection structure between the guide rod and the upper template of the flatbed cutting machine, as well as the design of the guide rod itself. In actual operation, the ejector pin device can be moved to a suitable position in the X and Y axes by adjusting the upper template of the flatbed cutting machine or fine-tuning the connection point between the guide rod support and the upper template. This multi-dimensional adjustment mechanism (including the adjustment of the number, angle, and planar position of ejector pins) can better adapt to the shape and porous structure of different products, ensuring that ejector pin 26 can accurately and efficiently eject waste material under various production conditions, thus ensuring the smooth progress of the production process and the stability of product quality.

[0064] In summary:

[0065] 1. In this device, the limiting lifting plate 2 is snapped into the first mounting frame 3 on one side, and the two are tightly connected to ensure the synchronization of movement. The carefully designed sliding groove 8 on the outer side of the guide support rod 7 slides with the second mounting frame 4. This design allows the second mounting frame 4 to slide smoothly in the sliding groove 8, while restricting its freedom in other directions, ensuring the stability of the entire motion system. The first mounting frame 3 and the second mounting frame 4 have the same structure and are interconnected. Both sides of them are fitted with connecting collars 21, and connecting rods 20 are snapped between the connecting collars 21. The bolt holes 22 on the connecting rods 20 are evenly distributed at a specific interval for installing mounting blocks 16. The mounting blocks 16 are fixed to the connecting rods 20 by the tight fit of the fixing bolts 23 with the bolt holes 22, ensuring that there will be no loosening during operation. A connecting column 17 connects the mounting blocks 16 on the first mounting frame 3 and the second mounting frame 4. The bottom of the connecting column 17 is firmly snapped into the adjuster 18 to form a stable force transmission link.

[0066] 2. After processing between the upper template 12 and the lower template 11, the material is transferred to the discharge platform 9. The discharge platform 9 is located on the top of the workbench 1, near the guide support rod 7, and its top slot 15 has special design considerations. The shape, size, and position of the slot 15 are carefully designed according to the waste processing flow and material characteristics. Its shape is similar to a basin, which is conducive to the centralized collection and guidance of waste. The release film covering the discharge platform 9 can be precisely cut according to the size of the product hole. This not only effectively prevents the material from sliding or shifting on the discharge platform 9, but also ensures that the waste smoothly passes through the release film, separates from the product, and enters the slot 15.
