Description

Technical Field

[0001] The utility model belongs to the technical field of textile washing, and in particular relates to a textile washing shrinkage sample holder. Background Art

[0002] The textile wash shrinkage test is an important means of evaluating the dimensional changes and performance stability of textiles during the wash process. During this testing process, the specimen holder is a key piece of equipment, used to secure the specimen and ensure its stability and consistency during the wash process. The design and performance of the specimen holder directly impact the accuracy and reliability of the test results. The basic function of a textile wash shrinkage specimen holder is to secure the specimen during the wash process, preventing it from shifting or deforming under the action of water and mechanical forces. Traditional specimen holders typically use mechanical clamping methods, such as clips and splints. These holders secure the specimen by applying a certain amount of mechanical force, but they have some significant drawbacks.

[0003] Disadvantages of traditional textile wash shrinkage specimen holders: Traditional holders typically use metal clamps or plates. These hard materials can easily scratch, indent, or otherwise damage the specimen surface when clamping. This damage not only affects the specimen's appearance but can also alter its physical properties, leading to inaccurate test results. The clamping force of traditional holders is often concentrated at the contact points of the clamps or plates, resulting in uneven force distribution on the specimen. This uneven clamping force can cause excessive force in some areas of the specimen and insufficient clamping in others, compromising the consistency and reliability of test results. Due to the limited clamping force of traditional holders, specimens may slip or shift during laundering. This slippage prevents accurate measurement of specimen dimensional changes, affecting the accuracy of test results. Traditional holders are often complex to operate, requiring manual adjustment of the clamping force, which must be readjusted for each test. This not only increases the operator's workload but also introduces potential for human error, impacting the repeatability and reliability of test results. Utility Model Content

[0004] In view of this, the utility model provides a textile washing shrinkage sample holder, which solves the disadvantage that traditional holders easily cause scratches, indentations or other forms of damage to the sample surface, and maintains the integrity and physical properties of the sample.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a textile washing shrinkage sample holder, which includes a holder body, a rubber tube, an air inlet and an air outlet valve. The rubber tube is arranged in the internal cavity of the holder body and is arranged along the circumferential direction of the holder body. The air inlet and the air outlet valve are both connected to the rubber tube. The air inlet is located at one end of the holder body and is connected to an external air source. The air outlet valve is located at the other end of the holder body. The air outlet valve is used to adjust the air pressure in the rubber tube. A sample placement area is provided at the center of the holder body, a base is provided at the bottom of the holder body, and the rubber tube is arranged around the sample placement area.

[0007] The technical effects of this utility model's textile wash shrinkage sample holder are as follows: By inflating a rubber tube, the tube expands and comes into close contact with the sample, achieving a seamless grip. The cylindrical design of the holder's main body helps evenly distribute pressure, ensuring the sample remains stable during testing.

[0008] Inflation: By inflating air into the rubber tube, the rubber tube expands and comes into close contact with the sample, thereby achieving seamless clamping of the sample.

[0009] Uniform pressure: The expansion of the rubber tube can be evenly distributed on the surface of the sample, avoiding damage to the sample caused by excessive local pressure.

[0010] Air pressure adjustment: The air pressure in the rubber tube is adjusted by the air outlet valve to ensure that the clamping force is moderate, so that the specimen can be firmly clamped without causing damage to it.

[0011] On the basis of the above technical solution, the textile washing shrinkage sample holder of the present invention can also be improved as follows:

[0012] The interior of the clamp body is a hollow cylindrical structure, the internal cavity is cylindrical, and the rubber tube is arranged in a ring shape along the inner wall of the cylindrical cavity, matching the shape of the inner wall of the clamp body.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the cylindrical design ensures that the rubber tube can expand evenly when inflated, provides uniform clamping force, and avoids deformation of the sample caused by local uneven force.

[0014] Furthermore, the annular inner diameter of the rubber tube is smaller than the diameter of the cylindrical cavity.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the inner diameter design of the rubber tube ensures that the rubber tube is close to the inner wall when not inflated, and can expand evenly after inflation to achieve all-round clamping of the sample.

[0016] Furthermore, the sample placement area and the base of the holder body are an integrally formed structure, the sample placement area is circular or rectangular, and the sample placement area is located on the axial center line of the holder body.

[0017] The beneficial effects of adopting the above-mentioned improved solution are as follows: the design of the sample placement area ensures the stability and central placement of the sample during the test, and avoids deviation and sliding of the sample.

[0018] Furthermore, when the rubber tube is not inflated, a gap of 0.1 mm to 0.5 mm is left between the outer surface of the rubber tube and the inner wall of the clamp body.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the wall thickness design of the rubber tube ensures its strength and flexibility when inflated, avoiding rupture caused by being too thin and uneven expansion caused by being too thick.

[0020] Furthermore, the length of the rubber tube is equal to or greater than the length of the inner cavity of the clamp body.

[0021] The beneficial effect of adopting the above-mentioned improvement scheme is that the length design of the rubber tube ensures that it can completely cover the sample placement area after inflation, thereby achieving all-round clamping of the sample.

[0022] Furthermore, the connection between the rubber tube and the clamp body is a snap connection, there are multiple snaps, and the snaps are installed on the inner wall of the clamp body by welding or bonding.

[0023] The groove or hole of the buckle is oriented toward the center of the holder body so that the rubber tube can pass through. The rubber tube is fixed by the groove or hole on the buckle, ensuring that the rubber tube does not shift during inflation.

[0024] Furthermore, the wall thickness of the rubber tube is between 0.5 mm and 2 mm, and the surface of the rubber tube is provided with an anti-slip texture, and the anti-slip texture is integrally formed with the rubber tube to increase friction with the sample.

[0025] The anti-slip texture includes, but is not limited to, dot-shaped, wavy, and grid-like projections. Made from the same material as the rubber tube, the micro-texture increases friction between the tube and the specimen, ensuring specimen stability and preventing slippage during testing.

[0026] Furthermore, the air inlet and the air outlet valve are both provided with sealing rings, and the air inlet is provided with a filter screen.

[0027] Choose common micro air valves on the market, such as air valves with G1 / 4 threaded interface. The specific model can be selected according to actual needs, such as "SMC VU2100 series" or "Festo VUV series".

[0028] Furthermore, the rubber tube is made of synthetic rubber.

[0029] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the use of synthetic rubber ensures the durability and chemical stability of the rubber tube, thereby extending the service life of the clamp.

[0030] Compared with the prior art, the textile washing shrinkage sample holder provided by the present invention has the following beneficial effects:

[0031] 1. Seamless clamping:

[0032] This new model achieves seamless clamping of the specimen through pneumatic expansion of the inner liner, avoiding mechanical damage to the specimen caused by traditional clamps. The softness and uniform expansion characteristics of the rubber tube ensure that the specimen is not damaged during the clamping process, maintaining the integrity and physical properties of the specimen.

[0033] 2. Uniform clamping force:

[0034] The rubber tubes are arranged along the circumference of the gripper body. When inflated, they can squeeze the specimen evenly from all sides toward the center, ensuring that the specimen is evenly stressed. This uniform clamping force avoids excessive force or insufficient clamping in certain areas of the specimen, improving the consistency and reliability of test results.

[0035] 3. Prevent the sample from sliding:

[0036] The surface of the rubber tube is finely textured, increasing friction with the specimen, ensuring specimen stability and preventing slippage during testing. Even when subjected to water and mechanical forces during washing, the specimen remains in place, avoiding measurement errors caused by dimensional changes.

[0037] 4. Easy to operate:

[0038] The gripper of this utility model is easy and quick to operate, as it is inflated and deflated through an air inlet and an air outlet valve. The user only needs to inflate the rubber tube through the air inlet to clamp the sample, without the need for complex mechanical adjustments. After the test is completed, the air is released through the air outlet valve, and the rubber tube returns to its original state, making it easy to remove the sample.

[0039] 5. Wide range of applications:

[0040] The flexible design of this new clamp is suitable for specimens of different materials, thicknesses, and shapes. The expansion coefficient of the rubber tube is precisely calculated to accommodate specimens of different sizes, ensuring moderate clamping force. This avoids the limited applicability of traditional clamps and reduces testing costs and complexity.

[0041] 6. Strong durability:

[0042] The rubber tube is made of synthetic rubber material with good elasticity and chemical resistance, ensuring its durability and chemical stability in multiple uses. The holder body is made of stainless steel or aluminum alloy material, with good corrosion resistance and mechanical strength, prolonging the service life of the equipment.

[0065] Specifically, the principle of the present utility model is:

[0066] 1. Working principle of pneumatic expansion liner:

[0067] The core technology of this utility model lies in the pneumatic expansion lining, which is to expand the rubber tube by inflating it with air, thereby achieving a traceless clamping of the sample. The specific working principle is as follows:

[0068] Installation of rubber hose:

[0069] The rubber tube is installed in the internal cavity of the gripper body, close to the inner wall. The inner diameter of the rubber tube is slightly smaller than the inner diameter of the gripper body, ensuring that the rubber tube is close to the inner wall when not inflated and can expand evenly after inflation;

[0070] Inflation:

[0071] Air is added to the rubber tube through the air inlet to expand it. The expansion coefficient of the rubber tube is precisely calculated to ensure that it can generate sufficient clamping force without damaging the specimen. During the inflation process, the inner wall of the rubber tube will expand evenly, forming an all-round clamping of the specimen.

[0072] Uniform clamping force:

[0073] The rubber tubes are arranged along the circumference of the gripper body and, when inflated, can evenly squeeze the specimen from all sides toward the center. This uniform clamping force avoids excessive force or insufficient clamping in certain areas of the specimen, improving the consistency and reliability of test results.

[0074] Anti-slip design:

[0075] The surface of the rubber tube is provided with fine texture, which increases the friction with the sample, ensures the stability of the sample during the test process and prevents slipping. Even if the sample is subjected to water and mechanical action during washing, it can remain in a fixed position, avoiding measurement errors due to dimensional changes;

[0076] Air pressure adjustment:

[0077] The air pressure inside the rubber tube is adjusted by the air outlet valve, ensuring moderate clamping force. If the clamping force is too small, it can be inflated further; if the clamping force is too large, it can be appropriately deflated through the air outlet valve. The design of air pressure adjustment ensures the controllability and flexibility of clamping force, adapting to samples of different materials and thicknesses;

[0078] 2. Design of the clamping body:

[0079] Cylindrical design:

[0080] The clamping body is cylindrical in shape, with a hollow cylindrical structure inside. This design ensures that the rubber tube can expand uniformly when inflated, providing uniform clamping force and avoiding deformation of the sample caused by uneven local stress;

[0081] Material selection:

[0082] The clamping body is made of stainless steel or aluminum alloy, which has good corrosion resistance and mechanical strength. The selection of these materials ensures the durability and stability of the clamp during multiple uses, extending the service life of the equipment;

[0083] Sample placement area:

[0084] The sample placement area is located at the center of the clamping body, i.e. on the axial centerline of the cylindrical clamping body. The size of the sample placement area matches the size of the standard sample, ensuring that the sample can be placed flatly. The design of the sample placement area ensures the stability and central placement of the sample during the test process, avoiding the displacement and sliding of the sample;

[0085] 3. Design of the buckle connection:

[0086] Shape and connection method of the buckle:

[0087] The buckle is designed in L or T shape, depending on the inner wall structure of the clamping body and the installation requirements of the rubber tube. The buckle is fixed to the inner wall of the clamping body by welding, bonding or screw connection, etc. One buckle is set every 5-10 cm, ensuring that the rubber tube can be evenly fixed during installation;

[0088] Installation of the rubber tube:

[0089] The rubber tube is fixed by the grooves or holes on the buckle, ensuring that the rubber tube is close to the inner wall when not inflated and can expand evenly after inflation. The buckle design ensures the stable installation of the rubber tube and avoids displacement and falling off during inflation;

[0090] 4. Design of air inlet and outlet valve:

[0091] Air Inlet:

[0092] The air inlet is located at one end of the gripper body and is connected to the rubber tube. A filter screen is installed in the air inlet to prevent dust and impurities from entering the rubber tube. The air inlet design facilitates the inflation of the rubber tube, ensures a stable supply of air, and improves the convenience and reliability of operation.

[0093] Outlet valve:

[0094] The outlet valve, located at the other end of the gripper body, connects to the rubber hose. This valve can be opened and closed manually or automatically, allowing the user to adjust the air pressure within the hose as needed. The valve's design ensures an airtight seal, preventing gas leakage and enhancing the gripper's reliability and safety.
