[0023] A punching device for thin products, see Figures 1-3 It includes a bottom mold 1 and a top mold 11 that engages with the bottom mold 1. A pre-cutting mechanism 2 for pre-cutting thin products and a punching mechanism 3 for punching and blanking thin products are sequentially arranged between the bottom mold 1 and the top mold 11 along the conveying direction.
[0024] The bottom mold 1 is provided with a feeding channel 4 below the punching mechanism 3, and the bottom mold 1 is provided with a feeding mechanism 5 at the feeding channel 4, through which the thin product is guided out of the feeding channel 4.
[0025] In this embodiment, the material strip is pre-cut at the pre-cutting mechanism 2 through the mold closing operation of the bottom mold 1 and the top mold 11. Then, the material strip moves the product to the punching mechanism 3, where the pre-cut product is completely cut. The punched product falls into the feeding channel 4, and the feeding mechanism 5 guides the product out of the feeding channel 4 for collection. This completes the punching of thin products, avoiding the accumulation and blockage of thin products in the feeding channel 4, and ensuring the smooth progress of subsequent production.
[0026] Specifically, the pre-cutting mechanism 2 includes a pre-cutting blade 21 disposed on the top mold 11 and a pre-cutting station 22 disposed on the bottom mold 1. Through the closing of the bottom mold 1 and the top mold 11, the pre-cutting blade 21 will complete the multi-face cutting of the thin product at the pre-cutting station 22.
[0027] Since the thin products on the strip are connected together, they need to be cut from the strip first. However, considering the thinness of the products, they are cut twice, pre-cut. Through the mold closing of the bottom mold 1 and the top mold 11, the pre-cutting blade 21 cuts the thin products connected to the strip on three or two sides at the pre-cutting station 22, so as to facilitate the preparation for the second cutting.
[0028] Specifically, the blanking mechanism 3 includes a blanking cutter 31 disposed on the top mold 11 and a blanking station 32 disposed on the bottom mold 1. Through the closing of the bottom mold 1 and the top mold 11, the blanking cutter 31 completes the cutting of the excess surface of the thin product at the blanking station 32.
[0029] Based on the pre-cutting mechanism, the punching cutter 31 completes the trimming of the remaining surface of the thin product at the punching station 32 through the mold closing of the bottom mold 1 and the top mold 11. This trimming of the remaining surface refers to the remaining connection surface between the thin product and the strip.
[0030] Specifically, the feeding mechanism 5 includes an inflation channel 51 located in the bottom mold 1. The inflation channel 51 is connected to the feeding channel 4. The air outlet of the inflation channel 51 is located at the top of the feeding channel 4. The inflation channel 51 is intermittently inflated by connecting with an external inflation device.
[0031] After the punching station 32 has punched the thin product, the air channel 51 is inflated by an external air inflator. The airflow is used to make the thin product flow out along the outlet of the unloading channel 4, thus completing the product unloading.
[0032] Specifically, the feeding mechanism 5 also includes a flow channel 52 disposed in the bottom mold 1. The flow channel 52 is connected to the feeding channel 4. The air outlet of the flow channel 52 is located below the inflation channel 51. The flow channel 52 is inclined and set towards the discharge outlet of the feeding channel 4. The flow channel 52 is connected to the external inflation device for intermittent inflation.
[0033] The external inflation device inflates the flow channel 52, creating an air pressure difference inside the discharge channel 4, which in turn promotes the flow of thin products along the discharge port of the discharge channel 4.
[0034] The external inflation device is an air inflator.
[0035] Specifically, protective covers 6 are provided at the pre-cutting mechanism 2 and the punching mechanism 3 to ensure the independent operation of the two stations, the pre-cutting station 22 and the punching station 32, and to reduce interference from the external environment.
[0036] See Figure 4 Specifically, the discharge port of the feeding channel 4 is provided with a fixing mechanism for fixing the material tube or bottle body 7. The material tube or bottle body 7 is provided with a limiting groove 71. The fixing mechanism includes several pre-tightening springs 8, which abut against the limiting groove 71 to fix the material tube or bottle body 7.
[0037] The material tube or bottle body 7 facilitates the collection of thin products.
[0038] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
