[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] The embodiments of the present application disclose a circular knife cutting die and a die-cutting production device using the die.

[0026] Reference Figure 1 The circular knife die cutting production equipment comprises a frame 1 and a cutting station arranged on the frame 1. The frame 1 is provided with two sets of mounting plates 2 at the cutting station. A circular knife cutting die 3, a pressure roller 4 and a tension roller 5 are rotatably mounted between the two sets of mounting plates 2. The circular knife cutting die 3 and the pressure roller 4 are arranged up and down. The tension roller 5 is arranged in front of the circular knife cutting die 3 along the conveying direction of the material belt.

[0027] Reference Figure 2 The circular knife cutting die 3 includes a core shaft 31, a knife roller 32 is coaxially fixed to the core shaft 31, a cutting knife 33 is arranged on the outer surface of the knife roller 32, and a transmission gear 6 is detachably fixedly connected to one end of the core shaft 31.

[0028] The detachable connection between the transmission gear 6 and the mandrel 31 can be set as a key connection, a threaded connection or a connection through a fastener. In this embodiment, the fastener can be set as a truncated cone-shaped plug cover 7 with a center hole, the center hole of the plug cover 7 is a threaded hole, and a threaded section is arranged at one end of the mandrel 31, so that the plug cover 7 can be screwed on the mandrel 31.

[0029] A clamping block and a clamping groove are respectively provided on the side of the transmission gear 6 facing the knife roller 32. After the transmission gear 6 is sleeved on the core shaft 31, it abuts against the knife roller 32. The setting of the clamping block and the clamping groove can make the transmission gear 6 more stably installed, thereby ensuring the transmission effect of the transmission gear 6.

[0030] A connecting hole that matches the shape of the blocking cover 7 is provided on the side of the transmission gear 6 facing away from the knife roller 32. Elastic sheets 61 are evenly distributed along the circumference of the wall of the connecting hole. A gap is left between the elastic sheet 61 and the wall of the connecting hole. After the blocking cover 7 is screwed and squeezed on the transmission gear 6, the truncated cone-shaped part of the blocking cover 7 enters the connecting hole of the transmission gear 6 to squeeze the elastic sheet 61. At the same time, the elastic sheet 61 applies a reverse thrust to the blocking cover 7, thereby preventing the blocking cover 7 from loosening and achieving stable installation of the transmission gear 6.

[0031] A gear is installed at one end of the pressure roller 4, which meshes with the transmission gear 6 of the circular knife cutting die 3. The pressure roller 4 cooperates with the circular knife cutting die 3 to cut the material strip.

[0032] When the circular knife die-cutting production equipment performs the final slitting work, the product strip is first tensioned by the tension roller 5, and then cut by the circular knife cutting die 3 and the pressure roller 4, and the slitting process of the product is completed.

[0033] In this solution, the transmission gear 6 of the circular knife cutting die 3 is set as an independent detachable part. Through the asynchronous segmentation process, the transmission gear 6 of the circular knife cutting die 3 is divided into several tooth number specifications, that is, a variety of circular knife products can share one cutting knife. Before the slitting work, the cutting die with the corresponding number of teeth is selected in advance according to the cutting size of the product, thereby greatly reducing the number of circular knife cutting dies 3, saving warehouse space, and facilitating the search and installation of machines. Parameters can be set for multiple products to achieve cutting pieces with different numbers of teeth, thereby achieving high-precision, high-speed, quality and quantity production of products, saving tool costs, saving tool search time, and greatly improving the production speed and yield of finished products.

[0034] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application.
