Abstract
Description
Technical Field
[0001] This utility model relates to the field of circular cutting auxiliary technology, and more specifically, to a circular cutting auxiliary device for a multilayer composite glass fiber folded film. Background Technology
[0002] Multilayer composite glass fiber membranes are prized for their excellent thermal insulation, tensile strength, and lightweight properties. However, circular cutting presents several technical challenges. For instance, due to the difference in mechanical properties between the glass fiber layer (brittle) and the polymer layer (tough), traditional cutting tools (such as rotary blades and stamping dies) are prone to causing interlayer delamination or edge burrs, affecting the sealing and structural integrity of the finished product. Furthermore, the difference in mechanical properties between the glass fiber layer (brittle) and the polymer layer (tough) means that existing cutting devices often rely on manual positioning or unidirectional clamping fixtures, leading to problems such as coaxiality errors and center offset in circular cutting.
[0003] When glass fiber membranes are folded and cut with a traditional rotary cutter, tangential forces can easily cause the circular surface to deform and become embedded in the cutter. If a ring cut is used, the folded filter membrane will inevitably spring open during cutting and cannot be shaped.
[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0005] The purpose of this invention is to provide a circular cutting auxiliary device for multi-layer composite glass fiber folded membranes. This circular cutting auxiliary device alleviates the damage to the membrane material caused by the cutting tool, effectively prevents the risk of the folded filter membrane being embedded in the ring cutter, reduces the tangential force released when the membrane material is partially cut, and ensures the integrity and roundness of the filter cake.
[0006] This utility model provides a circular cutting auxiliary device for multilayer composite glass fiber folded film, including a main unit, a base, a pressure rod, a pressure plate, and a ring cutter; the base is square plate-shaped, with a through hole in the middle and connecting holes at the four corners; the ring cutter is annular, with a cutting edge at its lower end and its upper end fixedly connected to the bottom of the base, the axis of the through hole and the axis of the ring cutter coincide; the pressure rod passes through the through hole, and the pressure plate is fixedly connected to its lower end, with external threads on the side of the upper end of the pressure rod, and the diameter of the pressure plate is smaller than the inner diameter of the ring cutter.
[0007] Using the above technical solution, during assembly, the base is connected to the output end of the main unit via bolts passing through the connecting holes at the corners, and the pressure rod is connected to the output end of the main unit via external threads; the ring cutter is connected to the base via injection molding or embedding process, with the inner diameter tolerance controlled within ±0.05mm to achieve high-precision fit with the processed parts; during use, the filter membrane is fixed on the worktable of the main unit, and under the control of the servo motor, the output end of the main unit drives the ring cutter to rotate and descend at a set rate to rotate and press down to cut the filter membrane. After cutting, the ring cutter rises, and the pressure plate on the pressure rod presses down on the cut filter cake and delays its ascent.
[0008] Furthermore, a circular groove is provided on the lower part of the base, and the ring cutter is connected in the circular groove.
[0009] Furthermore, the height of the ring cutter is greater than the thickness of the pressure plate.
[0010] This invention relates to a circular cutting auxiliary device for multi-layer composite glass fiber pleated membranes. During assembly, the base is connected to the output end of the main unit via bolts passing through the corner connection holes. The pressure rod is connected to the output end of the main unit via external threads. The ring cutter is connected to the base via injection molding or embedding, with an inner diameter tolerance controlled within ±0.05mm to achieve high-precision fit with the workpiece. In use, the filter membrane is fixed on the worktable of the main unit. Under the control of a servo motor, the output end of the main unit drives the ring cutter to rotate and descend at a set rate, rotating and pressing down to cut the filter membrane. After cutting, the ring cutter rises, and the pressure plate on the pressure rod presses down on the cut filter cake, delaying its ascent. This invention uses cutter rotation to reduce pressure during the downward pressing process, accelerating the cutting while mitigating damage to the membrane material. The delayed ascent of the pressure rod effectively prevents the risk of the pleated filter membrane embedding into the ring cutter. Through CNC programming, the speed of the cutter's descent is controlled, reducing the tangential force released when the membrane material is partially cut, ensuring the integrity and roundness of the filter cake.

After the cutting is completed, the ring cutter 4 rises, and the pressure plate 3 on the pressure rod 2 presses down on the cut filter cake and delays its rise.
[0033] The circular cutting auxiliary device of this utility model uses the rotation of the cutter to reduce the pressure during the downward pressing of the cutter, which accelerates the cutting while mitigating the damage to the membrane material by the cutter; the delayed rise of the pressure rod 2 effectively prevents the risk of the folded filter membrane being embedded in the ring cutter 4; through CNC programming, the speed of the cutter when it descends is controlled, reducing the tangential force released when the membrane material is partially cut, thus ensuring the integrity and roundness of the filter cake.
