Description

Technical Field

[0001] The utility model relates to the technical field of circular knife die-cutting equipment, in particular to a striping traction integrated device. Background Art

[0002] The circular die-cutter, also known as the "multi-station rotary die-cutter", is a machine that continuously rotates in the form of a roller to perform die-cutting. It is widely used in the production and processing of products in the fields of liquid crystal display, digital cameras, automobiles, lithium batteries, semiconductors, medical devices, etc. In the production process of the product, the material strip is cut, pulled, cut, punched, and many other processes are completed on the circular die-cutter. The processed material strip has multiple finished products arranged side by side, so a slitting device is needed to slit it.

[0003] After the product processing is completed, according to the actual distribution of the products on the material strip, the slitting device on the slitting knife seat is used to cut the material strip into several strips, and then the traction device on the traction knife seat is used to pull the material strip to the next process for subsequent processing. The slitting work is performed alone on the slitting knife seat. Since the manufacturing cost of the knife seat is very high, the structure of the separate slitting device increases the cost investment of production, and the separate knife seat requires an independent power source to drive, resulting in higher energy consumption in production.

[0004] Therefore, a strip-drawing integrated device is needed that can solve the above problems. Utility Model Content

[0005] The utility model provides a slitting and traction integrated device, which realizes the integrated setting of a slitting mechanism and a traction mechanism, solves the problem of increased energy consumption due to the separate setting of the slitting mechanism, and reduces the production cost investment.

[0006] The technical solution of the utility model is achieved in this way:

[0007] The slitting and pulling integrated device comprises a pulling knife seat, on which a pulling mechanism for pulling the material strip forward is installed, and two vertical plates are arranged on the feeding side of the pulling knife seat, each of which is fixed on the pulling knife seat, and a slitting mechanism for slitting the material strip is installed on the two vertical plates;

[0008] The slitting mechanism includes a horizontally arranged upper knife shaft and a lower knife shaft, both ends of the upper knife shaft are rotatably mounted on the corresponding vertical plate through a bearing seat, a plurality of slitting upper knives are axially arranged on the upper knife shaft, and both ends of the lower knife shaft are rotatably mounted on the corresponding vertical plate, the upper knife shaft and the lower knife shaft are driven to rotate by the traction mechanism, and a plurality of slitting lower knives are fixedly mounted on the lower knife shaft, and the positions of the slitting lower knives correspond to the positions of the slitting upper knives one by one, and each of the slitting lower knives is used in conjunction with the corresponding slitting upper knife, and a support mechanism for supporting the material strip is commonly mounted on the upper knife shaft and the lower knife shaft.

[0009] As a preferred technical solution, the support mechanism includes a first support ring arranged between the two lower strip knives, the first support ring is fixedly installed on the lower knife shaft, both ends of the lower knife shaft are fixedly installed with a second support ring, and both ends of the upper knife shaft are fixedly installed with a pressure ring, and the position of each pressure ring corresponds to the position of the corresponding second support ring.

[0010] As a preferred technical solution, each of the vertical plates is provided with a vertically arranged guide groove, each of the bearing seats is arranged in the corresponding guide groove, each of the bearing seats is fixedly mounted on the corresponding vertical plate through an adjusting block, and an adjusting screw is threadedly mounted on the top of each of the vertical plates along the vertical direction, and the lower end of each of the adjusting screws is fixedly connected to the corresponding bearing seat.

[0011] As a preferred technical solution, the traction mechanism includes a transmission bottom shaft, a traction lower roller and a traction upper roller which are arranged in sequence from bottom to top, and the transmission bottom shaft, the traction lower roller and the traction upper roller are all arranged to extend along the axial direction of the upper knife shaft and the lower knife shaft, the transmission bottom shaft is driven to rotate by a servo motor, a driving gear is fixedly installed at one end of the transmission bottom shaft, a first driven gear meshing with the driving gear is fixedly installed on the traction lower roller, and a second driven gear meshing with the first driven gear is fixedly installed on the traction upper roller.

[0012] As a preferred technical solution, a first intermediate gear and a second intermediate gear that mesh with each other are rotatably installed on the corresponding vertical plate, the first intermediate gear meshes with the first driven gear, a third driven gear that meshes with the second intermediate gear is fixedly installed on the lower knife shaft, and a fourth driven gear that meshes with the third driven gear is fixedly installed on the upper knife shaft.

[0013] As a preferred technical solution, a plurality of support rods are installed between the two vertical plates, and each of the support rods is extended along the axial direction of the upper knife shaft.

[0014] As a preferred technical solution, each of the vertical plates is fixedly mounted on the traction knife seat via a knife seat hanger.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0016] Since the slitting and traction integrated device includes a traction knife seat, the traction knife seat is equipped with a traction mechanism and a slitting mechanism. In the utility model, the slitting mechanism is directly installed on the traction knife seat and shares a knife seat with the traction mechanism, thereby realizing the integrated setting of the slitting mechanism and the traction mechanism, thereby eliminating the need to set up a separate slitting knife seat, reducing the manufacturing cost of the knife seat, and further reducing the cost investment in production.

[0017] Since the slitting mechanism includes an upper knife shaft and a lower knife shaft, both of which are driven by a traction mechanism, in the utility model, the slitting mechanism is driven by a servo motor on the traction mechanism, and there is no need to set a separate power source for the slitting mechanism, thereby solving the problem of increased energy consumption caused by the separate setting of the slitting mechanism.

[0018] Since a support mechanism is installed on the upper knife shaft and the lower knife shaft, the support mechanism includes a first support ring, a second support ring and a pressure ring. In the utility model, the support mechanism is used to support the material belt passing through the upper knife shaft and the lower knife shaft. The setting of the first support ring and the second support ring makes the material belt always in a tensioned state. The setting of the pressure ring makes the material belt flatly attached to the first support ring and the second support ring, thereby ensuring the accurate stripping of the material belt by the upper stripping knife and the lower stripping knife.

[0019] The adjusting screw drives the bearing seat and the upper knife shaft to move upward, thereby increasing the gap between the pressing ring and the second support ring, and between the upper knife and the lower knife of the stripping. On the contrary, when the thickness of the material strip is small, the adjusting screw is turned to move it downward, and the adjusting screw drives the bearing seat and the upper knife shaft to move downward, thereby reducing the gap between the pressing ring and the second support ring, and between the upper knife and the lower knife of the stripping. Therefore, the upper knife and the lower knife of the stripping can strip material strips of different thicknesses, thereby improving the applicability of the utility model and ensuring the pressing effect of the pressing ring on material strips of different thicknesses.

[0036] like Figure 1 As shown, each vertical plate 2 is fixedly mounted on the traction tool holder 1 via a tool holder hanger 26 .

[0037] The method of using the utility model is as follows:

[0038] In the first step, the servo motor 17 is started, and the motor shaft of the servo motor 17 drives the transmission bottom shaft 14 to rotate, and drives the traction upper roller 16 and the traction lower roller 15 to rotate through the power transmission of the gears.
