Description

Technical Field

[0001] The present invention relates to the technical field of cloth detection, in particular to a cloth waterproofness detection mechanism. Background Art

[0002] With the continuous progress of society, waterproof fabrics have gradually won wide popularity. The so-called waterproof fabric refers to a kind of fabric that is given waterproof function by coating or laminating PU, TPU, TPE and other materials on the surface of the fabric. In order to promote the widespread application of such waterproof fabrics, it is necessary to conduct strict testing on their waterproof performance.

[0003] A fabric waterproofness detection mechanism with the publication number CN218297954U specifically relates to the field of fabric detection technology, including a base, a support column is installed on the upper end surface of the base, a support plate is installed on the upper end of the support column, a balance is installed on the upper end of the support plate, a water collecting frame is provided on the upper end of the balance, a fixing rod is installed on the upper end of the base, a connecting rod is installed on the side end of the fixing rod, a support plate is installed on the other end of the connecting rod, a frame is installed on the top of the fixing rod, an electric telescopic rod is installed on the bottom end of the frame, a clamp is installed on the bottom end of the electric telescopic rod, a rubber strip is installed on the bottom end of the clamp, a water source box is installed on the top end of the frame, and a water outlet pipe is installed on the bottom end of the water source box. The patent uses the electric telescopic rod to drive the clamp and the rubber strip to move downward, and the clamp and the rubber strip fix the fabric on the support plate. The fixing step is simple to operate, and the waterproof effect can be known by the change of the weight of the balance, which effectively improves the accuracy of the detection.

[0004] The device evaluates the waterproof properties of fabrics by pressing them tightly together and observing the water seepage from the bottom. However, before testing the fabric, it is important to ensure that the fabric is properly tensioned on the test table. This is because if wrinkles appear in the middle of the fabric, its waterproof properties cannot be accurately assessed. In addition, the device pours water directly on the fabric during the test, and after the test is completed, there is still residual water on the surface of the fabric. If the fabric is removed at this time, water may spill into the device, resulting in the need for separate cleaning of the device later, which will consume a lot of valuable time. Summary of the invention

[0005] The object of the present invention is to provide a fabric waterproofness detection mechanism to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for detecting the waterproof performance of textile fabrics, comprising a basic support frame, a top bearing frame, a supporting column, a clamping mechanism, a detecting mechanism and a collecting mechanism, wherein the top bearing frame is firmly installed at the top position of the basic support frame, and the supporting column is located in the central part of the top bearing frame, the clamping mechanism is configured at the bottom of the top bearing frame and is connected to the bottom of the supporting column, the detecting mechanism and the collecting mechanism are both arranged in the middle area of ​​the basic support frame, the clamping mechanism is further composed of a lifting unit and a clamping unit, wherein the lifting unit is located at the bottom of the top bearing frame, and the clamping unit is fixed to the lower end of the lifting unit, the detecting mechanism is composed of a detecting unit, a water supply unit and a drainage unit, the detecting unit is arranged at the bottom of the supporting column, the water supply unit is located above the detecting unit, and the drainage unit is built into the detecting unit.

[0007] According to the above technical scheme, the lifting unit is composed of a power telescopic pump, a connecting block and a pressure plate. The top end of the power telescopic pump is installed on the bottom surface of the top carrier frame via a fixing device, and is symmetrically arranged on the top surface of the basic support frame to ensure the smooth lifting and lowering of the pressure plate. The connecting block is fixed to the bottom end of the power telescopic pump, and the pressure plate is fixed to the middle position of the connecting block. A through hole is provided in the middle of the pressure plate, and card grooves are provided on both sides of the top surface. The card groove cooperates with the card block to press the cloth into the card groove, thereby achieving stable fixation of the cloth.

[0008] According to the above technical scheme, the clamping unit is composed of a pressure rod, a handle, a sliding guide rail, a card block, a limit block and a first spring. The pressure rod is symmetrically installed on the top surface of the pressure plate. It is used in conjunction with the pressure plate to achieve the clamping of the cloth. The handle is fixed to the top surface of the pressure rod, which is convenient for the operator to lift the pressure rod to simplify the operation process.

When the pressure rod rises, the sliding guide rail also rises accordingly, thereby compressing the first spring. The bottom end of the sliding guide rail passes through the bottom end of the pressure plate and is installed and fixed. The card block is fixed to the bottom surface of the pressure rod and embedded in the card slot to further stabilize the cloth. The limit block is fixed to the surface of the sliding guide rail, and the first spring is installed on the surface of the sliding guide rail to ensure the stable operation of the clamping unit.

[0009] According to the above technical solution, the detection unit is composed of a water storage barrel and a water source box. The water storage barrel is fixedly installed on the bottom surface of the supporting column. Its shape is cylindrical, and the bottom is open. The opening size is larger than the leakage hole.

The second rubber ring is fixedly installed on the top of the movable tube, the top of the second spring is fixed to the bottom surface of the first rubber ring, and the bottom end thereof is fixed to the top surface of the second rubber ring. Through the action of the second spring, the bottom end of the water absorption tip can be closely attached to the cloth, thereby achieving thorough absorption of the water on the top surface of the cloth. The water absorption tip is fixedly installed on the bottom end of the movable tube, and its water absorption holes are respectively arranged on the left and right sides to ensure that when in close contact with the cloth, the water inside the water storage barrel can still be effectively absorbed.

[0012] According to the above technical solution, the collecting mechanism is composed of a positioning substrate and a collecting bin. The positioning substrate is firmly fixed to the central part of the base support frame, and the collecting bin is flexibly installed in the central area of ​​the positioning substrate. Through the installation of this collecting bin, the moisture leaked from the cloth can be effectively collected.

[0013] According to the above technical solution, the upper end of the first spring is fixed to the lower surface of the pressure plate, and the lower end of the first spring is installed on the upper surface of the limit block. By configuring the second spring, it is ensured that the pressure rod continuously applies a stable pressing force to the cloth.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The fabric waterproofness detection mechanism is equipped with a clamping mechanism. Pull the handle on the top of the pressure rod to make the sliding guide rail rise. Then, place one end of the fabric in the middle of the pressure plate and the pressure rod. The spring extends to make the pressure rod press the fabric on the top of the pressure plate. Then, perform the same operation on the other end of the fabric, thereby achieving the compression and fixation of the fabric. This effectively solves the problem of fabric wrinkles in the original device.

[0015] 2. The fabric waterproofness testing mechanism is configured to install a water supply unit in the testing mechanism and start the first water pump, so that the first water pump can transport the water in the water source box to the water storage barrel through the water inlet pipe, thereby achieving the goal of supplying water to the water storage barrel and testing the fabric.

[0016] 3. The fabric waterproofness testing mechanism can be equipped with a drainage unit in the testing mechanism and the second water pump can be turned on to pump the water used for testing in the water storage barrel back into the water source tank, thereby achieving the goal of recycling water resources.

[0017] 4. The fabric waterproofness testing mechanism installs the drainage unit in the testing mechanism, and the power telescopic pump retracts the pressure plate upward, so that the water suction tip contacts the fabric on the top surface of the pressure plate. During the contact process, the movable tube squeezes and contracts the second spring, so that the water suction tip always remains at the lowest point inside the water storage barrel. This process realizes the suction of water inside the water storage barrel after the test is completed, effectively solving the problem that the original device cannot collect water.
