Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane sample preparation technology, specifically a waterproof membrane cutting and sample preparation device. Background Technology

[0002] Waterproof membrane is a block-shaped waterproof material that can be rolled into rolls and manufactured in factories using special production processes. It is widely used in waterproofing projects in fields such as construction, transportation, and environmental protection. Waterproof membranes often have the following advantages: strong impermeability: effectively resisting the leakage of external rainwater and groundwater, and is impermeable under pressure water; high tensile strength: having high tensile strength and elongation, it can adapt to the deformation of the substrate without easily cracking; good weather resistance: having good water resistance, temperature stability, mechanical strength, flexibility, and aging resistance, and maintaining stable performance in various harsh environments.

[0003] Therefore, waterproof membranes need to be tested before leaving the factory. During testing, the waterproof membranes need to be cut and sampled. However, the existing technology often uses direct cutting, so it is often possible to cut and prepare samples one by one, which makes the sample preparation efficiency very low.

[0004] To address the aforementioned technical issues, a waterproof membrane cutting and sample preparation device was designed. Utility Model Content

[0005] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a waterproof roll material cutting and sample preparation device.

[0006] This utility model overcomes the above technical problems by adopting the following technical solution:

[0007] A waterproof membrane cutting and sample preparation device includes a frame, a placement plate on top of the frame, a cutting assembly on top of the placement plate, a cutting plate assembly connected to the bottom of the cutting assembly, the cutting plate assembly including a cutting plate and multiple sets of blades on the cutting plate, the multiple sets of blades forming multiple rectangular frames of the same size, and a positioning assembly on the placement plate for fixing the waterproof membrane.

[0008] Preferably, the blade has elastic strips surrounding both sides of its cutting edge, and the height of the elastic strips is 0.5-2mm higher than the height of the cutting edge.

[0009] Preferably, the cutting plate is provided with multiple through holes, and the elastic strip is fixed to the cutting plate by passing through the through holes with a fixing wire, which facilitates the replacement of the elastic strip. It can be replaced according to the damage of the broken elastic strip, thus saving costs.

[0010] Preferably, the cutting assembly includes a mounting bracket with a placement plate, a stamping cylinder on the mounting bracket, the stamping cylinder moving up and down, a connecting plate at the tail of the stamping cylinder, and the connecting plate being connected to the cutting plate assembly.

[0011] Preferably, the positioning component includes positioning plate components disposed on both sides of the cutting component, the positioning plate components include positioning frames, the positioning frames are linear frames, the positioning frames are provided with lifting cylinders at both ends, and the positioning frames are provided with pressing plates at the bottom.

[0012] Preferably, the bottom of the pressing plate is provided with an anti-slip layer.

[0013] Preferably, the connecting plate is detachably connected to the cutting plate assembly.

[0014] Preferably, the elastic strip is a rubber structural component, and the anti-slip layer is a rubber structural component.

[0015] Working Principle: In existing technologies, waterproof membranes require sampling for physical performance testing, often using direct cutting for sample preparation. However, this method is inefficient due to the need for dimensional accuracy. This application addresses this by first fixing the waterproof membrane using a positioning component. Specifically, the membrane is placed at the bottom of the positioning component, and then a lifting cylinder lowers the pressing plate to press and fix the membrane, preventing shifting during cutting. A stamping cylinder then drives the cutting plate assembly downwards to cut the waterproof membrane, allowing for simultaneous sample preparation. Furthermore, because the waterproof membrane is thin, the rigid platform of the mounting frame can cause the blade to curl under high pressure during cutting. Therefore, this application incorporates elastic strips on both sides of the blade, with the strips higher than the blade itself. This prevents the blade from contacting the mounting frame first due to impact during stamping, further protecting the blade.

[0016] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0017] 1. This utility model utilizes positioning and cutting components to simultaneously prepare multiple samples of waterproof membrane, resulting in high sample preparation efficiency.

[0018] 2. This utility model has elastic strips on both sides of the blade, and the height of the elastic strips is higher than the blade. Therefore, during the stamping process, the blade will not come into contact with the mounting bracket first due to the impact force, thus further protecting the blade.

[0019] 3. The cutting plate of this utility model is provided with multiple through holes, and the elastic strip is fixed to the cutting plate by passing through the through holes with a fixing wire, which makes it convenient to replace the elastic strip. It can be replaced according to the damage of the broken elastic strip, thus saving costs. Attached Figure Description

In a specific embodiment, four parallel vertical blades 402 are used to divide the cutting plate 401 into four sets of cutting frames, the rectangular frames being of the same size. Then, a horizontal blade 402 is provided at both ends of the four vertical blades 402, and the horizontal blades 402 and the vertical blades 402 thus form a closed rectangular frame. A positioning assembly 5 is provided on the placement plate 2, and the positioning assembly 5 is used to fix the waterproof membrane.

[0027] Furthermore, the positioning component 5 includes positioning plate components disposed on both sides of the cutting component 3. The positioning plate components include a positioning frame 501, which is a straight frame 1. The positioning frame 501 is provided with lifting cylinders 502 at both ends and a pressing plate 503 at the bottom.

[0028] Furthermore, the cutting assembly 3 includes a mounting bracket 301 on the placement plate 2, a stamping cylinder 302 on the mounting bracket 301, the stamping cylinder 302 moves up and down, and a connecting plate 303 is provided at the tail of the stamping cylinder 302, the connecting plate 303 being connected to the cutting plate assembly 4.

[0034] Working Principle: In existing technologies, waterproof membranes require sampling for physical performance testing, often using direct cutting for sample preparation. However, this method is inefficient due to the need for dimensional accuracy. This application addresses this by first fixing the waterproof membrane using a positioning component 5. Specifically, the waterproof membrane is placed at the bottom of the positioning component 5, and then a lifting cylinder 502 lowers a pressing plate 503 to press and fix the membrane, preventing displacement during cutting. Then, a stamping cylinder 302 drives the cutting plate component 4 downwards to cut the waterproof membrane, enabling simultaneous sample preparation. Furthermore, because the waterproof membrane is thin, the rigid platform of the placement frame can cause blade curling under high pressure during cutting. Therefore, this application incorporates elastic strips on both sides of the blade, with the strips higher than the blade itself. This prevents the blade from contacting the placement frame first due to impact during stamping, further protecting the blade.
