Description

Technical Field

[0001] The present application relates to the field of die-cutting machines, and in particular to an automatic continuous waste removal device and a die-cutting machine. Background Art

[0002] like Figure 1 As shown, the die-cut paper is divided into a finished product 100 and a waste 101 part, and the finished product 100 and the waste 101 are connected by a connection point 102. After the paper enters the waste removal device, the waste 101 is removed from the paper by the waste removal device.

[0003] In the related art, the patent with publication number CN207495662U discloses a waste cleaning mold of an automatic die-cutting machine, and its waste cleaning principle is: when working, the automatic die-cutting machine transports the die-cut paper to a preset position on the middle template 2, and then the lower template 3 rises until the upper end of the spring ejector 31 passes through the waste leakage hole 21 and sticks to the bottom of the paper, then the upper template 1 is pressed down, the paper presser 12 presses the paper, and the upper template 1 continues to press down. The upper waste cleaning needle presses the part of the paper to be removed together with the spring ejector 31 below to separate the paper scraps, and then the lower template descends and resets, the paper scraps fall, and finally the upper template rises and resets, and the automatic die-cutting machine transports the cleaned paper away, completing a waste cleaning work.

[0004] With regard to the above-mentioned related technologies, the removal of waste materials mainly relies on the upper waste cleaning needle and the lower waste cleaning needle to clamp the waste materials, and then the upper waste cleaning needle and the lower waste cleaning needle move downward as a whole, thereby realizing the separation of waste materials and paper. The above separation method is suitable for some papers with higher hardness, while for some papers with greater softness, the above separation method is not easy to remove the connection point 102, which affects the quality of paper. Summary of the invention

[0005] In order to effectively remove waste from paper with greater flexibility, the present application provides an automatic continuous waste removal device and a die-cutting machine.

[0006] In the first aspect, the present application provides an automatic continuous waste removal device and a die-cutting machine using the following technical solutions: An automatic continuous waste removal device, comprising: A female template, the upper surface of which is used to support the finished product; the female template is provided with waste removal holes matching the waste materials; An upper waste cleaning frame is arranged above the female template, and an upper waste cleaning needle is installed in the upper waste cleaning frame; A lower waste stripping frame is arranged below the female template, and a lower waste stripping needle is installed in the lower waste stripping frame; Among them, the upper waste cleaning needle and the lower waste cleaning needle are staggered and diagonally arranged. When removing waste, the upper waste cleaning needle descends and the lower waste cleaning needle rises to separate the waste from the finished product in a diagonally inclined manner. At this time, the waste is clamped between the upper waste cleaning needle and the lower waste cleaning needle, and then the upper waste cleaning needle and the lower waste cleaning needle descend to pass the clamped waste through the waste cleaning hole, and then the upper waste cleaning needle stops descending and rises, and the lower waste cleaning needle continues to descend, and the waste falls to the bottom of the lower waste cleaning frame under the action of gravity.

[0007] By adopting the above technical solution, the staggered diagonal setting of the upper waste cleaning needle and the lower waste cleaning needle enables the waste to be effectively separated in a diagonally inclined manner, avoiding the problem of waste residue that may be caused by the traditional vertical up and down movement. At the same time, this design also reduces the adhesion between the waste and the finished product, further improving the success rate of waste removal. In addition, through the coordinated movement of the upper waste cleaning needle and the lower waste cleaning needle, it is ensured that the waste is discharged smoothly at the waste cleaning hole and finally falls under the lower waste cleaning frame under the action of gravity. The whole process is smooth and reliable, achieving efficient and stable removal of waste, and improving production efficiency and product quality.

[0008] Optionally, a first suction hole is opened on the upper surface of the female template, a second suction hole is opened on the hole wall of the waste cleaning hole, and a suction channel is opened in the female template, the suction channel is connected with the first suction hole and the second suction hole, the first suction hole is used to absorb the finished product, and the second suction hole is used to absorb the waste and the connection point between the waste and the finished product downward.

[0009] By adopting the above technical solution, the first suction hole is arranged on the upper surface of the female template, which can stably absorb the finished product and ensure that the finished product will not be displaced during the waste cleaning process, thereby improving the quality and stability of the finished product. The hole wall of the waste cleaning hole is provided with a second suction hole, which can absorb the waste and its connection points downward during the separation of the waste and the finished product, preventing the detached connection points from adhering to the finished product, further ensuring the waste cleaning effect.

[0010] Optionally, the first air suction hole is arranged on the peripheral side of the waste cleaning hole.

[0011] By adopting the above technical solution, the upper waste cleaning needle and the lower waste cleaning needle mainly operate the waste of the finished product at the waste cleaning hole, that is, only the finished product around the waste needs to be stabilized, which can ensure the subsequent waste cleaning. This method can improve the fixing effect of the finished product around the waste, thereby improving the subsequent waste cleaning effect.

[0012] Optionally, the waste cleaning device also includes a middle frame, the female template is installed on the middle frame, and the middle frame and the lower waste cleaning frame are connected with a first driving mechanism, and the first driving mechanism is used to drive the middle frame and the lower waste cleaning frame to rise or fall synchronously, and the rising or falling amplitude of the lower waste cleaning frame is greater than the rising or falling amplitude of the middle frame so that the lower waste cleaning needle can move relative to the female template.

[0013] By adopting the above technical solution, the design enables the middle frame and the lower waste stripping frame to rise or fall synchronously, but the lower waste stripping frame has a larger movement range, thereby ensuring that the lower waste stripping needle can move relative to the female template during the waste stripping process. This structure not only improves the waste stripping efficiency, but also reduces mechanical wear and extends the service life of the equipment. The large-scale lifting and lowering movement of the lower waste stripping frame helps to better coordinate the movement of the upper waste stripping needle, realize the complete separation and discharge of waste, and avoid product quality problems caused by waste residue. At the same time, this design also facilitates waste collection and processing, and improves the automation level of the entire production process.

[0014] Optionally, the first driving mechanism includes: Side stand; A first driving swing frame and a second driving swing frame are coaxially arranged and rotatably connected to the side bracket; A lower frame transmission assembly, one end of which is connected to the first driving swing frame, and the other end of which is connected to a lower waste stripping frame, wherein the lower waste stripping frame is vertically slidably connected to the side bracket; A middle frame transmission assembly, one end of which is connected to the second driving swing frame, and the other end of which is connected to the middle frame, and the middle frame is slidably connected to the side bracket in the vertical direction; Wherein, the first driving swing frame and the second driving swing frame swing synchronously to realize synchronous movement of the lower waste removal frame and the middle frame.

[0015] By adopting the above technical solution, the first driving mechanism can ensure the synchronous movement of the lower waste cleaning frame and the middle frame, thereby ensuring the coordinated movement of the upper waste cleaning needle and the lower waste cleaning needle during the waste cleaning process.

[0016] Optionally, the lower frame transmission assembly includes: The lower frame transmission beam is fixed to the first driving swing frame; A lower frame transmission bearing is connected to the lower waste removal frame, and the bottom side of the lower frame transmission bearing is in sliding contact with the top side of the lower frame transmission crossbeam; The middle frame transmission assembly comprises: A middle frame connecting plate, one end of which is rotatably connected to the second driving swing frame, and the other end of which is rotatably connected to the middle frame; A middle frame tension spring, one end of which is connected to the middle frame, and the other end of which is connected to the side bracket, wherein the middle frame tension spring has elastic potential energy for pulling the middle frame downward.

[0017] By adopting the above technical solution, the design of the lower frame transmission assembly and the middle frame transmission assembly enables the lower waste stripping frame and the middle frame to achieve precise synchronous movement, ensuring that the relative displacement between the lower waste stripping needle and the female template is accurate during the up and down movement. At the same time, the presence of the middle frame tension spring ensures that the middle frame is always in a downward pulling state, improving the stability and reliability of the entire waste stripping process. This design effectively avoids the risk of incomplete waste removal or damage to the finished product due to the matching error between components, and significantly improves production efficiency and product quality.

[0018] Optionally, the female template is detachably connected to the middle frame, and a female template supporting assembly for supporting the female template is provided in the middle frame, and the position of the female template supporting assembly in the middle frame is adjustable.

[0034] The following will be combined with the attached Figure 1-7 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0035] The inventor of the present application discovered that the problem existing in the prior art is that the waste cleaning process for paper with greater flexibility is inefficient and easily produces waste residue. For this reason, the present application mainly adopts the following automatic continuous waste cleaning device to achieve the effect of improving waste cleaning efficiency and reducing waste residue. The present application is further described in detail below.

[0036] The automatic continuous waste removal device provided in the embodiment of the present application refers to Figure 2 and Figure 3, including a female template 1, an upper waste cleaning frame 2 and a lower waste cleaning frame 3. The finished product 100 is transported to the upper surface of the female template 1 through the paper gripper row, and the upper surface of the female template 1 is used to support the finished product 100; the female template 1 is provided with a waste cleaning hole 11 matching the waste 101. The upper waste cleaning frame 2 is arranged above the female template 1, and an upper waste cleaning needle 21 is installed in the upper waste cleaning frame 2. The lower waste cleaning frame 3 is arranged below the female template 1, and a lower waste cleaning needle 31 is installed in the lower waste cleaning frame 3. The upper waste cleaning needle 21 and the lower waste cleaning needle 31 are staggered and diagonally arranged. When the waste 101 is removed, the upper waste cleaning needle 21 descends and the lower waste cleaning needle 31 rises to separate the waste 101 from the finished product 100 in a diagonally inclined manner. At this time, the waste 101 is clamped between the upper waste cleaning needle 21 and the lower waste cleaning needle 31, and then the upper waste cleaning needle 21 and the lower waste cleaning needle 31 descend to pass the clamped waste 101 through the waste cleaning hole 11, and then the upper waste cleaning needle 21 stops descending and rises, and the lower waste cleaning needle 31 continues to descend, and under the action of gravity, the waste 101 falls below the lower waste cleaning frame 3, thereby achieving the effect of improving the waste cleaning efficiency and reducing the residue of waste 101.

[0037] Specifically, the diameter of the waste cleaning hole 11 on the female template 1 can be adjusted according to the size of the waste 101 , and is generally slightly larger than the size of the waste 101 .

[0038] Reference Figure 4 and Figure 5 The waste cleaning device further comprises a middle frame 4, the female template 1 is detachably connected to the middle frame 4, a positioning block 41 is provided on the side of the middle frame 4, the positioning block 41 is used to position the female template 1, and a female template support assembly 5 for supporting the female template 1 is provided on the bottom side of the middle frame 4, and the position of the female template support assembly 5 in the middle frame 4 is adjustable.

[0039] Specifically, the female template support assembly 5 includes a female template support bracket 51, a support bracket adjustment shaft 52, a support bracket adjustment gear 53 and a support bracket adjustment rack 54. The female template support bracket 51 is slidably connected to the middle frame 4 along the conveying direction of the finished product 100. The support bracket adjustment shaft 52 is rotatably connected to the female template support bracket 51. The support bracket adjustment gear 53 is fixed to the support bracket adjustment shaft 52. The support bracket adjustment rack 54 is fixed to the middle frame 4. The support bracket adjustment rack 54 is meshed with the support bracket adjustment gear 53. By rotating the support bracket adjustment shaft 52, the support bracket adjustment gear 53 can be rolled on the support bracket adjustment rack 54, thereby adjusting the position of the female template support bracket 51, thereby realizing the adjustment of the position of the female templates 1 of different sizes. At the same time, the female template support bracket 51 can also be avoided below the waste removal hole 11 to ensure the normal dropping of the waste 101.

[0040] Reference Figure 6In a preferred embodiment, the upper surface of the female template 1 is further provided with a first suction hole 12, the hole wall of the waste removal hole 11 is provided with a second suction hole 13, and a suction channel 14 is provided in the female template 1, the suction channel 14 is connected with the first suction hole 12 and the second suction hole 13, and one end of the suction channel 14 can be connected to a negative pressure system. The first suction hole 12 is used to absorb the finished product 100 to prevent it from moving during the waste removal process, and the second suction hole 13 is used to absorb the waste 101 and the connection point 102 separated from the waste 101 and the finished product 100 downward, thereby enhancing the separation effect of the waste 101.

[0041] In the present application, since the waste 101 is separated from the finished product 100 by diagonally tilting, during the separation process, the connection point 102 between the waste 101 and the finished product 100 may fall off and adhere to the upper surface of the finished product 100. When the finished products 100 are subsequently stacked, the connection point 102 is easily imprinted on the surface of the finished product 100, thereby affecting the surface quality of the finished product 100. Therefore, the detached connection point 102 can be discharged through the second suction hole 13 to ensure the surface quality of the finished product 100.

[0042] Optionally, a blocking net can be set at the air inlet of the second air inlet hole 13 to prevent the connection point 102 from entering the second air inlet hole 13 and blocking the air inlet channel 14. When the air inlet stops, the connection point 102 falls under the action of gravity. It is also possible not to set a blocking net at the air inlet of the second air inlet hole 13, so that the connection point 102 is sucked into the air inlet channel 14 and discharged through the air inlet channel 14.

[0043] Furthermore, the first air suction holes 12 can be evenly distributed around the waste cleaning hole 11. Since the waste 101 is mainly operated during the waste cleaning process, the position of the finished product 100 around the waste 101 is stabilized, which can improve the separation effect of the waste 101.

[0044] Among them, refer to Figure 2 and Figure 7 The middle frame 4 and the lower waste stripping frame 3 are connected with a first driving mechanism 6, and the first driving mechanism 6 is used to drive the middle frame 4 and the lower waste stripping frame 3 to rise or fall synchronously. The rising or falling amplitude of the lower waste stripping frame 3 is greater than the rising or falling amplitude of the middle frame 4, so that the lower waste stripping needle 31 can move relative to the negative template 1.

[0045] Preferably, the first driving mechanism 6 includes a side bracket 61, a first driving swing frame 62, a second driving swing frame 63, a lower frame transmission assembly and a middle frame transmission assembly. The first driving swing frame 62 and the second driving swing frame 63 are rotatably connected to the side bracket 61 through the same rotating shaft 64. The first driving swing frame 62 and the second driving swing frame 63 are arranged at the four corners of the lower waste material 101 frame, and the rotating shaft 64 can be driven to reciprocate by the telescopic driving member, thereby driving the first driving swing frame 62 and the second driving swing frame 63 to swing back and forth. Optionally, the telescopic driving member can be a hydraulic cylinder or a cylinder.

[0046] The lower frame transmission assembly includes a lower frame transmission beam 65 and a lower frame transmission bearing 66. The lower frame transmission beam 65 is rotatably mounted between the two first drive swing frames 62. The lower frame transmission bearing 66 is mounted on the side of the lower waste stripping frame 3. The bottom side of the lower frame transmission bearing 66 is in sliding contact with the top side of the lower frame transmission beam 65. The lower waste stripping frame 3 and the middle frame 4 are vertically slidably connected with the side bracket 61, so that when the first drive swing frame 62 reciprocates, the lower waste frame 101 can be driven to reciprocate and rise and fall.

[0047] Reference Figure 2 and Figure 7 Preferably, the middle frame transmission assembly includes a middle frame connecting plate 67 and a middle frame tension spring 68. One end of the middle frame connecting plate 67 is rotatably connected to the second driving swing frame 63, and the other end is rotatably connected to the middle frame 4. One end of the middle frame tension spring 68 is connected to the middle frame 4, and the other end is connected to the side bracket 61. The middle frame tension spring 68 has elastic potential energy to pull the middle frame 4 downward. Therefore, when the second driving swing frame 63 reciprocates, it can drive the middle frame 4 to reciprocate and rise and fall. At the same time, by designing the transmission ratio and transmission mode of the middle frame transmission assembly and the lower frame transmission assembly, the amplitude of the rise or fall of the lower waste stripping frame 3 is greater than the amplitude of the rise or fall of the middle frame 4, so that the lower waste stripping needle 31 can move relative to the female template 1. The function of the lower waste stripping frame 3 being able to rise and fall is to provide a more compact structural design. After the lower waste stripping frame 3 is lowered, it can allow the paper gripper row to pass through, and when it rises, it can ensure the normal progress of the waste stripping process.

[0048] The upper waste cleaning frame 2 is connected to a second driving mechanism, and the structure and principle of the second driving mechanism are similar to those of the first driving mechanism 6, which will not be described in detail here.

[0049] Reference Figure 4 and Figure 5 In a preferred embodiment, the upper waste cleaning frame 2 and the lower waste cleaning frame 3 both include a fixed frame 71 and a frame body 72 slidably connected to the fixed frame 71, the upper waste cleaning needle 21 or the lower waste cleaning needle 31 are both arranged in the frame body 72, and the frame body 72 can slide into or out of the fixed frame 71 from the side, and the fixed frame 71 is provided with a locking member 73 for locking the position of the frame body 72.

[0050] Specifically, the fixing frame 71 is slidably connected with the side bracket 61 in the vertical direction, and the fixing frame 71 can be made of cast iron material, which has good rigidity and wear resistance. The frame body 72 can also be made of aluminum material to reduce weight while ensuring sufficient strength.

[0051] A sliding crossbeam 74 and a sliding seat 75 are provided between the upper waste cleaning needle 21 or the lower waste cleaning needle 31 and the frame body 72. The sliding crossbeam 74 is connected to the frame body 72 by sliding in the transverse direction, and the sliding seat 75 is connected to the sliding crossbeam 74 by sliding in the longitudinal direction. The upper waste cleaning needle 21 or the lower waste cleaning needle 31 is installed on the sliding seat 75. By adjusting the sliding crossbeam 74 and the sliding seat 75, the position of the upper waste cleaning needle 21 or the lower waste cleaning needle 31 can be adjusted to match the waste cleaning hole 11. In the drawings of the present application specification, only one upper waste cleaning needle 21 or lower waste cleaning needle 31 is shown. In practice, the number and position of the upper waste cleaning needle 21 or the lower waste cleaning needle 31 must match the number and position of the waste cleaning holes 11.

[0052] Preferably, the locking member 73 includes a locking block, which is detachably connected to the side of the fixing frame 71, and the locking block abuts against the two sides of the frame body 72 to fix the frame body 72. Optionally, a handle 76 is provided on the side of the frame body 72 to facilitate the extraction of the frame body 72 and to quickly replace the upper waste cleaning needle 21 or the lower waste cleaning needle 31.

[0053] In addition, a waste collection box may be provided below the lower waste removal frame 3, and the waste 101 may be recycled through the waste collection box.

[0054] The implementation principle of this embodiment is as follows: the staggered diagonal setting of the upper waste cleaning needle 21 and the lower waste cleaning needle 31 enables the waste 101 to be effectively separated in a diagonally inclined manner, avoiding the problem of waste 101 residue that may be caused by the traditional vertical up and down movement. At the same time, this design also reduces the adhesion between the waste 101 and the finished product 100, further improving the success rate of removing the waste 101. In addition, through the coordinated movement of the upper waste cleaning needle 21 and the lower waste cleaning needle 31, it is ensured that the waste 101 is smoothly discharged at the waste cleaning hole 11, and finally falls under the lower waste cleaning frame 3 under the action of gravity. The whole process is smooth and reliable, achieving efficient and stable removal of the waste 101, and improving production efficiency and product quality.

[0055] The embodiment of the present application also discloses a die-cutting machine, including the above-mentioned automatic continuous waste removal device. By integrating the automatic continuous waste removal device, the die-cutting machine has a higher degree of automation and waste removal efficiency, which is particularly suitable for large-scale production scenarios. The various components of the automatic continuous waste removal device can be seamlessly connected with the functional modules of other die-cutting machines to ensure the smooth operation of the entire production line.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
