Description

Technical Field

[0001] This utility model relates to the field of cleanroom cloth testing technology, specifically a device for extracting square test samples from cleanroom cloths. Background Technology

[0002] Cleanroom wipes, also known as cleanroom cleaning cloths, are commonly found on the market to be made of polyester-nylon composite yarn. After the fibers are opened, the cross-section of the yarn presents a petal shape, the surface is soft, it is easy to wipe sensitive surfaces, does not shed fibers when rubbed, and has good water absorption and cleaning efficiency.

[0003] After refining, cleanroom wipes experience fiber breakage and detachment due to the different shrinkage rates of the polyester and nylon components in the polyester-nylon composite yarn. This often results in a petal-shaped cross-section after fiber opening, allowing for the removal of more dirt. However, precisely because of this difference in shrinkage rate, it's necessary to test the shrinkage rate of the cleanroom wipes before cutting to ensure dimensional stability of the finished product and guarantee that the dimensions after washing meet customer requirements. Since cleanroom wipes often exhibit significant differences in shrinkage rates in the radial and weft directions, they must be cut into square sizes to allow for testing of both radial and weft shrinkage rates.

[0004] Common shrinkage rate testing cutting methods require workers to manually measure dimensions and complete the process through two transverse cuts and two longitudinal cuts. This process is labor-intensive, monotonous, and tiring for workers, which is not conducive to the rapid detection of the shrinkage rate of cleanroom fabrics. Utility Model Content

[0005] The purpose of this invention is to provide a device for extracting square test samples from a cleanroom cloth, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for extracting square test sample cloth from a cleanroom cloth, comprising a fixed base rod, a sleeve, a fixed arm, and a fixed crossbeam. One end of the fixed crossbeam is fixed to the middle of the fixed base rod, and the other end of the fixed crossbeam is fixed to the fixed arm. The fixed base rod is fixed to the bottom of the fixed arm, and the sleeve is fixed to the front end of the fixed arm. An ear seat is fixed to the front side of the sleeve, and a cutter head fixing post passes through the sleeve. A connecting piece is fixed to the fixed arm by bolts, and the connecting piece is connected to one end of a connecting rod by a rotating... Shaft 1 is movably connected together. The other end of connecting rod 1 is movably connected to one end of connecting rod 2 via shaft 4. The other end of connecting rod 2 is movably connected to connecting rod 3 via shaft 3. A pressure rod is fixed at the front end of connecting rod 3. The rear end of connecting rod 3 is movably connected to ear seat via shaft 2. A square cutter head is fixed at the bottom of the cutter head fixing post. A platform is provided corresponding to the square cutter head. A spring limiting pin is provided at the upper part of the cutter head fixing post. The spring is sleeved on the cutter head fixing post and is located between the spring limiting pin and the sleeve.

[0007] Preferably, the top of the cutter head fixing post is a raised arc shape.

[0008] Preferably, the second connecting rod is in the shape of the letter "L".

[0009] Preferably, the platform is fixed at the connection between the fixed arm and the fixed crossbeam.

[0010] This utility model relates to a device for extracting square test samples of cleanroom wipes. In use, the device first determines the size of the cleanroom wipe sample and manufactures a square cutter head 12, which is then fixed to the bottom of a cutter head fixing post 6. Next, the cleanroom wipe to be cut is laid flat on a platform 11, and a pressure rod 9 is pressed down. The pressure rod 9 drives multiple connecting rods, causing connecting rod 5 to press down on the cutter head fixing post 6, thereby causing the square cutter head 12 to cut out a sample of the desired size of cleanroom wipe and release it. Finally, after cutting, under the restoring force of a spring 7, the cutter head fixing post 6 moves upward, moving the square cutter head 12 away from the platform 11, preparing for the next cutting. In summary, this device can cut out a square sample of cleanroom wipe in one operation, reducing the labor intensity of workers and improving the efficiency of cleanroom wipe cutting and testing, making it suitable for widespread use.
