Description

Technical Field

[0001] This utility model relates to the technical field of composite membrane residue testing equipment, and in particular to a cutting and preparation device for testing composite membrane test samples. Background Technology

[0002] Composite films are multi-layered films formed by bonding various plastics with paper, metals, or other materials through processes such as lamination, extrusion, and co-extrusion. Different types of plastic composite films require sample testing to meet national standards before they can be marketed. According to the standards "Dry Lamination and Extrusion Lamination of Plastic Composite Films and Bags for Packaging" (GB / T10004-2008) and "General Rules for Pharmaceutical Composite Films and Bags" (YBB00132002-2015), the solvent residue sample preparation method requires "cutting a 0.2 m..." 2 The sample to be tested was cut into 10 mm × 30 mm fragments; according to the sample preparation method in "Determination of Phthalate Esters and Migration in Food Contact Materials and Articles" (GB 31604.30-2016), "cut 5 g of sample into individual fragments with a diameter ≤ 0.2 cm"; and according to the sample preparation method for the dissolution test in "General Rules for Pharmaceutical Composite Films and Bags" (YBB00132002-2015), "take samples with an inner surface area of ​​600 cm² of each sample". 2 "Divide it into small pieces that are 3 cm long and 3 cm wide", etc.

[0003] Composite membranes for different applications require different testing standards, and the size of the cut samples also varies.

[0049] Working principle:

[0050] This utility model relates to a cutting and preparation device for testing composite membrane samples. When in use:

[0051] 1. Place the raw materials into the feed trough of the raw material table, turn the hand crank, and the first cutting component will vertically cut the raw materials. The conveyor roll assembly and the pressure film damping roll assembly will push the raw materials forward.

[0052] 1.1 Cutting: The first gear drives the second gear to rotate, and the second gear drives the circular cutting blade to rotate, thus performing the first cut on the material;

[0053] 1.2 Movement: The third gear drives the fourth gear to rotate via the second conveyor belt. The fourth gear drives the conveyor roller below the raw material to rotate, and the raw material moves forward. At the same time, the first conveyor belt drives the pressure film damping roller to rotate. When rotating, the raw material is brought into the system and pressed down to keep the material flat.

[0054] 2. Driven by the first conveyor belt, the ejector plate of the pressure film damping roller moves forward (the raw material is under the pressure film damping roller). When the ejector plate of the pressure film damping roller reaches the spring clip, it starts to push the automatic spring clip to move until the clip falls off. Under the pressure of the spring, the pressing table moves upward to the fixed clamping plate (at this time, the raw material is clamped between the pressing table and the fixed clamping plate).

[0055] 3. The first conveyor belt continues forward, pressing the top plate of the pressure film damping roller until the front top block separates from the top plate of the pressure film damping roller; after separation, the top plate of the pressure film damping roller slowly retracts; at this time, the raw material is fixed between the pressing table and the fixed clamping plate and cannot be retracted.

[0056] 4. Press the hand lever handle to cut the raw material horizontally through the second cutting component. The material after vertical cutting is in strip shape, and then the material after horizontal cutting is in block shape. The raw material after the two cuts falls into the receiving trough (finished product).

[0057] The size of the sample can be adjusted by changing the distance between the blades of the two cutting components according to the required sample size.

[0058] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
