Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and specifically relates to a semi-automatic plate chain disassembly machine. Background Technology

[0002] In practical applications, the required length of plate chains varies, and most purchased plate chains are large coils exceeding tens of meters in length. Therefore, it is necessary to split these coils to obtain the required length. However, traditional chain disassembly processes typically rely on manual operation, which is not only inefficient and labor-intensive but also prone to operator fatigue and errors, thus affecting production efficiency and product quality. Furthermore, manual disassembly poses certain safety hazards. To address these issues, developing a semi-automatic disassembly device is crucial. Improving the automation level of chain disassembly, reducing manual labor intensity, and enhancing production efficiency and safety are research topics for those skilled in the art. Utility Model Content

[0003] This invention provides a simple and efficient semi-automatic plate chain disassembly machine.

[0004] A semi-automatic plate chain disassembly machine includes a plate chain feeding device, which works in conjunction with a plate chain disassembly device. The plate chain disassembly device includes a plate chain flattening device, a plate chain positioning device, a pin disassembly device, and a pin riveting device. The plate chain flattening device includes a first guide wheel, a second guide wheel, and a third guide wheel spaced vertically. A guide rod is located at the bottom of the third guide wheel, and a sprocket driven by a first motor is positioned on the lower side of the guide rod. The sprocket meshes with and connects to the plate chain. This invention automatically introduces the plate chain into the pin disassembly device via the plate chain feeding device. The precise alignment of the pin holes by the plate chain positioning device enables rapid removal of the pins from the plate chain. Subsequently, the pin riveting device manually rivets the disassembled pins back into the pin holes. The entire process achieves semi-automatic operation of feeding, pin disassembly, and riveting, making operation simpler and more efficient.

[0005] The third guide wheel is axially connected to the second cylinder via a lifting slider. The lifting slider has an extension section on its side, which is connected to a guide rod via a pressure block. Driven by the second cylinder, the lifting slider raises and lowers the third guide wheel. Adjusting the height of the third guide wheel allows for the adaptation to different specifications of plate chains, ensuring the plate chain is in the correct position when meshing with the sprocket and effectively preventing the plate chain from tilting. The guide rod further ensures the plate chain is smoothly introduced into the pin disassembly device.

[0006] The plate chain positioning device includes a first cylinder, the push rod of which is connected to a positioning seat. A positioning block is engaged within the positioning seat, and the positioning block presses against the plate chain. The plate chain is located within a pin-removing guide rail. A first cylinder seat is provided on one side of the pin-removing guide rail to fix the first cylinder, and a first stop is provided on the other side. The pin-removing device includes a punch driven by a first hydraulic cylinder, which engages with the pin hole of the plate chain. Precise positioning of the plate chain is achieved through the positioning block, ensuring that the punch is accurately aligned with the pin hole. Under the action of the punch, the pin can quickly detach from the plate chain, making the entire disassembly process both fast and stable. Furthermore, the first stop prevents displacement of the pin-removing guide rail due to impact during disassembly, further improving the accuracy and efficiency of the disassembly.

[0007] The pin riveting device includes a riveting head die seat driven by a second hydraulic cylinder, the riveting head die seat is connected to a riveting guide rail, and a second stop is connected to the other side of the riveting guide rail.

[0008] The plate chain feeding device includes a base plate with at least two guide rails. The guide rails are connected to a material roll frame seat via sliders. The material roll frame seat supports and connects a first feeding frame and a second feeding frame. The first and second feeding frames are driven to move along the guide rails by a screw device. The screw device includes a main pulley driven by a first motor. The main pulley drives a driven pulley via a belt. The driven pulley drives a screw, and the screw drives a screw nut seat base plate via a screw nut seat. The screw nut seat base plate is fixedly connected to the material roll frame seat, thereby enabling the first and second feeding frames to move along the guide rails, ensuring that the plate chain can be transferred to the first guide wheel, thus achieving automatic feeding of the plate chain.

[0009] The first and second feeding frames are installed as a set of two plate chain reels.

[0010] This invention introduces a plate chain into a pin disassembly device. By precisely aligning the pin hole with the plate chain positioning device, the pin on the plate chain can be quickly removed. Subsequently, the pin riveting device manually rivets the dismounted pin into the pin hole. The entire process realizes semi-automatic operation of feeding, pin disassembly, and riveting, making the operation simpler and more efficient. Attached Figure Description
