Description

Technical Field

[0001] The utility model relates to the technical field of continuous cutting machines, in particular to a continuous cutting machine. Background Art

[0002] In traditional blister production lines, blister forming machines and cutting machines are key production equipment used to manufacture thermoplastic products of various shapes. The blister forming machine uses the vacuum suction force generated by a vacuum pump to blister the heated and softened plastic strip through a mold into a product. The cutting machine uses a mold to punch out and separate the formed product from the strip.

[0003] However, in traditional cutting machines, there is a key problem with the loading station, which is the lack of an accurate positioning mechanism. This technical defect directly leads to the unstable position of the strip during the cutting process, which often shifts or is in an improper position. This situation has a negative impact on the accuracy and stability of the product, and further leads to an increase in the scrap rate. What's worse, in order to correct this problem, additional manual operations are often required to manually adjust and maintain the machine, which undoubtedly reduces the stability and efficiency of the entire production line.

[0034] The die-cutting assembly 20 includes a lower die-cutting seat 21 installed in the middle of the frame 10, and an upper die-cutting seat 22 that can be raised and lowered above the lower die-cutting seat 21; the upper die-cutting seat 22 and the lower die-cutting seat 21 are used for the material belt to pass through, and the upper die-cutting seat 22 is used to press down to cut the material belt to cut out the product.

[0036] Specifically, the opposite ends of the upper crossbar 35 are respectively used to connect the piston rod of the lifting cylinder 37, and the upper pressing plate 36 can be driven to move up and down through the lifting cylinder 37. The opposite ends of the lower crossbar 32 are respectively used to connect the ends of the hand wheel 34, and the height position of the lower pressing plate 33 can be adjusted through the hand wheel 34, so as to cooperate with the upper pressing plate 36 to position and clamp the material strips of different thickness specifications.

[0037] In this embodiment, the end of the lower pressing plate 33 away from the die-cutting assembly 20 is bent in an arc shape, and the end of the upper pressing plate 36 away from the die-cutting assembly 20 is bent in an arc shape, which can conveniently guide the material strip into the feed channel between the lower pressing plate 33 and the upper pressing plate 36.

[0038] The loading conveyor assembly 40 includes a bearing frame 41 mounted on the top of the bracket 31, a synchronous belt 42 arranged along the length direction of the bearing frame 41, a driving motor 43 installed at one end of the synchronous belt 42, a moving beam 44 slidably connected to the middle of the bearing frame 41, a first cantilever 45 connected to the opposite ends of the moving beam 44, a second cantilever 46 fixedly connected to the opposite sides of one end of the bearing frame 41, a clamp 47 respectively installed on the inner side of each first cantilever 45 and the inner side of each second cantilever 46, and a positioning sensor 48 respectively installed on the outer side of each second cantilever 46.
