Technical Field
[0001] This utility model relates to the field of rubber sheet processing technology, specifically to a high-efficiency cutting and edge treatment device for flame-retardant rubber sheets. Background Technology
[0002] Flame-retardant rubber sheets, as a material with excellent fire-resistant properties, are widely used in industries such as construction, automotive, and electronics for critical components such as sealing, insulation, or protection. The core processes in their processing include precise cutting and meticulous edge treatment: cutting aims to divide large sheets into specific sizes and shapes to meet assembly requirements; edge treatment removes burrs, flash, and irregular edges generated during cutting through grinding, ensuring a smooth and flat surface and preventing stress concentration, sealing failure, or safety hazards during use. This process demands extremely high precision because rubber materials have elasticity and toughness; improper handling can easily lead to deformation, tearing, or dimensional deviations, thus affecting the performance and lifespan of the final product. Traditional cutting and edge treatment often require separate equipment or workstations. Operators must manually move the rubber sheet between the cutting machine and the grinding machine, which is not only time-consuming and labor-intensive, increasing production costs, but may also cause material damage or contamination during the handling process. In addition, the existing device's fixing mechanism for the rubber sheet is not stable enough, and it is prone to displacement or vibration during cutting. Therefore, we propose a high-efficiency cutting and edge treatment device for flame-retardant rubber sheets. Utility Model Content

[0016] The working principle of the high-efficiency cutting and edge treatment device for flame-retardant rubber sheets provided by this utility model is as follows: First, the operator places the flame-retardant rubber sheet on the placement frame 1, and the external PLC controller starts the first hydraulic rod 2 to drive the connecting frame 3 forward to the edge of the flame-retardant rubber sheet, thereby ensuring that the blade 73 in the cutting and grinding assembly 7 is accurately located at the edge of the rubber sheet. After adjustment, the second hydraulic rod 11 is started, causing the guide frame 41 to move downward and drive the blade 73 downward to insert into the edge of the flame-retardant rubber sheet. Then, the external PLC controller controls the lower fourth hydraulic rod 81 to work and drive the fastening frame 82 downward to press and fix the edge of the rubber sheet to prevent displacement. After fixing, the first motor 46 of the moving assembly 4 drives the threaded rod 44 to rotate, and the moving frame 42 slides inside the guide frame 41. The strip-shaped opening of the rubber sealing strip 48 seals the moving gap, and the blade 73 performs efficient cutting of the flame-retardant rubber sheet. After cutting, the control... The second hydraulic rod 11 retracts, causing the guide frame 41 to rise. Then, the second motor 52 is started to drive the right rotating shaft 47 to rotate, causing the guide frame 41 to rotate. At this time, the third hydraulic rod 61 of the fixing component 6 retracts, causing the chuck 62 to disengage from the slot 64 of the fixing ring 63, and the grinding wheel 75 is switched to the lower position. Subsequently, the fourth hydraulic rod 81 corresponding to the grinding wheel 75 is started, pushing the fastening frame 82 to press down on the edge of the rubber plate for secondary fixation. Finally, the third motor 77 is started to drive the grinding wheel 75 to rotate at high speed. Then, the grinding wheel 75 is moved to the right by the moving component 4 to perform fine grinding on the cutting edge, removing burrs and flash. The whole process realizes the integrated operation of cutting and edge processing, improving efficiency and processing accuracy. During the movement of the moving frame 42, the two pressure sensors 43 will work continuously. When one pressure sensor 43 contacts the inner wall of the guide frame 41, the external PLC controller will automatically control the first motor 46 to shut down.
[0017] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The first hydraulic rod 2, the second hydraulic rod 11, the third hydraulic rod 61, the fourth hydraulic rod 81, the first motor 46, the second motor 52, the third motor 77, the pressure sensor 43, and the brush slip ring 53 can be freely configured according to the actual application scenario.
