Description

Technical Field

[0001] The utility model relates to the technical field of material strip processing, in particular to a pneumatic knife pressing mechanism. Background Art

[0002] During the processing of the material strip, a knife pressing device is required according to the production process of the material strip. The driving mechanism of the traditional knife pressing device is mostly a manual screw rod or a hydraulic cylinder. The free ends of the manual screw rod and the hydraulic cylinder are against the pressure roller lifting frame on which the pressure roller is installed, which makes the pressure roller only able to press down but not rise. When installing the material strip, the pressure roller lifting frame needs to be lifted manually, which is troublesome to operate. Some pressure roller lifting frames are connected to the manual screw rod or the hydraulic rod with a connecting device that is not easy to disassemble. After adopting the connecting device, although it is convenient to install the material strip, the drive component will inevitably malfunction and be damaged during use. Since the connecting device cannot be quickly disassembled, the drive component cannot be removed separately, which makes the replacement and disassembly of the drive component troublesome.

[0003] Therefore, a pneumatic knife pressing mechanism is needed to solve the above problems. Utility Model Content

[0004] The utility model provides a pneumatic knife pressing mechanism, which realizes the rapid and stable connection and rapid replacement between the knife pressing assembly and the knife pressing cylinder through a quick-release assembly, so that the pressing wheel mounting frame can simultaneously complete the lifting and lowering of the pressing wheel.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The pneumatic knife pressing mechanism comprises a knife seat, and a knife pressing assembly is installed on the two side plates of the knife seat through a pair of quick-release assemblies, and a knife pressing cylinder mounting seat is detachably mounted on the top of the knife seat, and two knife pressing cylinders are vertically arranged on the knife pressing cylinder mounting seat, and each of the quick-release assemblies comprises a limit mounting seat, and the piston rod of each knife pressing cylinder passes through the knife pressing cylinder mounting seat and is fixedly mounted with a limit plate, and each of the limit mounting seats is provided with a first limit groove for limiting the corresponding piston rod, and each of the limit mounting seats is also provided with a second limit groove for limiting the corresponding limit plate, and each of the first limit groove and the second limit groove is provided with an opening, and the opening directions of the openings of the two limit mounting seats are the same, and the knife pressing assembly comprises a pressing wheel lifting frame driven by the two knife pressing cylinders, and the two limit mounting seats are both installed on the top of the pressing wheel lifting frame.

[0007] As a preferred technical solution, the knife pressing cylinder mounting seat is detachably mounted on the top of the two side plates by two pairs of connecting bolts.

[0008] As a preferred technical solution, two pressing wheel mounting frames are adjustably mounted on each of the pressing wheel lifting frames, and a pair of pressing wheels are rotatably mounted on each of the pressing wheel mounting frames.

[0009] As a preferred technical solution, each of the pressure wheel mounting frames is mounted on the pressure wheel lifting frame via a limiting bolt.

[0010] As a preferred technical solution, the knife pressing cylinder mounting seat and the pressing wheel lifting frame are both arranged horizontally.

[0011] As a preferred technical solution, each of the openings extends in a horizontal direction.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0013] Since the pneumatic knife pressing mechanism includes a quick-release component, when the material strip needs to be installed during the use of this mechanism, the two knife pressing cylinders drive the pressing wheel lifting frame to move up, so that the material strip can pass between the die-cutting bottom roller and the die-cutting roller, and then pass through the knife pressing cylinder, the pressing wheel lifting frame moves down, and the pressing wheel presses against the die-cutting bottom roller. Further, the material strip is pressed between the die-cutting bottom roller and the die-cutting roller, and the material strip begins to be processed under the drive of the driving motor. During the processing, when the driving cylinder needs to be replaced, the connecting bolts can be removed, and the knife pressing cylinder mounting seat can be pushed to move the two piston rods out of the corresponding first limit grooves. At this time, the driving cylinder can be It can be quickly removed from the tool holder for maintenance and replacement, and a new driving cylinder can be installed on the tool holder through the quick-release assembly and connecting bolts, and the material strip can continue to be processed, thereby not affecting the material strip processing and facilitating the maintenance of the driving cylinder. In the utility model, compared with the traditional top connection, the limit plate and the piston rod are hard connected, and the limit plate is installed on the limit mounting seat through the second limiting groove fiber, thereby realizing a fast and stable connection between the knife pressing assembly and the knife pressing cylinder, so that the knife pressing cylinder drives the pressing wheel mounting frame to realize automatic lifting of the pressing wheel, avoiding manual operation and facilitating the installation and removal of the material strip.

[0014] In the utility model, since the first limiting groove and the second limiting groove are provided on the limiting mounting seat, after the driving cylinder is connected to the knife pressing assembly through the quick-connect assembly, the first limiting groove limits the piston rod, and the second limiting groove limits the limiting plate. The two limits make the connection between the driving cylinder and the knife pressing assembly more stable. Due to the disc-shaped setting of the limiting plate, the contact area with the inner wall of the second limiting groove is reduced, making the connection and disassembly of the driving cylinder and the knife pressing assembly easier.

[0015] Since the pressure wheel mounting frames are mounted on the pressure wheel lifting frame by limiting bolts, in the utility model, the position of the pressure wheel on the pressure wheel lifting frame, that is, the position where the pressure wheel presses against the die-cutting bottom roller, can be adjusted according to the processing requirements of the material strip and the size of the die-cutting bottom roller, so that the pressure knife assembly can adapt to the processing requirements of various material strips and die-cutting bottom rollers of different sizes, thereby increasing the application range of the pressure knife assembly.
