Description

Technical Field

[0001] This utility model relates to the field of chemical fiber paper tube technology, and in particular to a device for testing the humidity resistance of chemical fiber paper tubes. Background Technology

[0002] In the chemical fiber and textile industry, paper tubes serve as the core carrier for yarn winding, and their moisture resistance directly affects the quality of yarn storage and transportation. If the paper tube deforms or loses strength after becoming damp, it may cause the yarn to loosen, break, or even affect subsequent textile processing. Therefore, moisture resistance testing of paper tubes is a crucial step in production quality control.

[0003] Current technologies typically employ fixed testing chambers to test the moisture resistance of paper tubes, using fixed nozzles inside the chamber to spray a localized area of ​​the paper tube. However, due to the limited spray range of static testing methods, the test data only reflects localized performance, making it difficult to comprehensively assess the actual moisture resistance characteristics of the paper tube, resulting in severely insufficient representativeness of the test results. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the spray range of the static detection method in the prior art is limited, resulting in the detection data only reflecting local performance, and proposes a humidity resistance testing device for chemical fiber paper tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A moisture resistance testing device for chemical fiber paper tubes includes a mounting base with an open front, a screw rotatably connected inside the mounting base, a motor for driving the screw to rotate fixed on the mounting base, a screw block threadedly connected to the screw, a liquid storage tank fixed on the top of the mounting base, and a carrier fixed at the bottom of the inner cavity of the mounting base.

[0007] Also includes:

[0008] A spray-wet pressing mechanism is provided on the screw block and is used to perform spray-wet pressing operations on the paper tube.

[0009] A fixing mechanism is provided on the carrier seat and is used to limit and fix the paper tube.

[0010] Preferably, the spray pressing mechanism includes a hose fixedly extending through the bottom of the liquid storage tank, a water pump fixed on the screw block, one end of the hose being connected to the water pump in a through manner, a liquid storage box being fixedly extending through the bottom of the water pump, and a spray head being fixedly extending through the bottom of the liquid storage box.

[0011] Preferably, the hose is embedded in and fixedly mounted on the mounting base.

[0012] Preferably, the spraying and pressing mechanism further includes a mounting plate fixedly connected to the bottom of the water pump, a cylinder fixedly connected to the bottom of the mounting plate, and a pressure plate fixed to the output end of the cylinder.

[0013] Preferably, the fixing mechanism includes a pair of rectangular plates fixedly connected to the vertical sidewall of the carrier, the two rectangular plates are rotatably connected to the same bidirectional lead screw on opposite sidewalls, a pair of connecting plates are threaded onto the bidirectional lead screw, a transmission rod is fixedly connected to the top of the connecting plate, and a clamping plate is fixedly connected to the transmission rod.

[0014] Preferably, one end of the bidirectional lead screw extends to the opposite sides of the two rectangular plates and is fixedly connected to a screw block, and the connecting plate and the carrier are horizontally slidably connected.

[0015] Preferably, the mounting base is fixedly connected to the bottom of the mounting base, and four support legs are fixedly connected to the bottom of the base.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] This invention, through the design of a spray-pressing mechanism and a fixing mechanism, allows for precise operation. During operation, simply rotating the screw block drives the bidirectional lead screw, enabling the clamping plates on both sides to move synchronously and quickly achieve stable fixing of the paper tube. During testing, a motor-driven screw moves the spraying mechanism horizontally, working in conjunction with a water pump to achieve uniform spraying and precise humidification of different parts of the paper tube. Subsequently, a cylinder drives the pressure plate to apply controllable pressure, simulating humidity stress under actual working conditions. This device supports multi-point testing, covering the entire length of the paper tube, ensuring comprehensive and representative data, thereby guaranteeing testing efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-3 A moisture resistance testing device for chemical fiber paper tubes includes a mounting base 1 with an open front, which facilitates operator observation and adjustment of the paper tube position, improving the convenience of the testing process. A screw 2 is rotatably connected inside the mounting base 1, and the screw 2 and screw block 4 are threadedly engaged to ensure precise movement of the spraying and pressing mechanism and avoid offset errors. A motor 3 is fixed on the mounting base 1 to drive the screw 2. The motor 3 provides stable power, and the movement speed is adjustable to adapt to different testing needs, improving testing efficiency and enabling multi-point testing while reducing manual intervention. A screw block 4 is threadedly connected to the screw 2. A liquid storage tank 5 is fixed to the top of the mounting base 1, and a carrier 6 is fixed to the bottom of the inner cavity of the mounting base 1.

[0025] Also includes:

[0026] The wet spraying and pressing mechanism is mounted on the screw block 4 and is used to wet and press the paper tube.

[0027] The fixing mechanism is set on the carrier 6 and is used to limit and fix the paper tube.

[0028] The spray-pressing mechanism includes a flexible hose 51 fixedly extending through the bottom of the liquid storage tank 5, and a water pump 52 fixed on the screw block 4. The water pump 52 and the liquid storage box 53 are integrated on the screw block 4 and operate synchronously with the screw block 4 to avoid liquid delivery delay. One end of the flexible hose 51 is connected to the water pump 52, and the bottom of the water pump 52 is fixedly extending through the liquid storage box 53. A spray head 54 is fixedly extending through the bottom of the liquid storage box 53. The spray head 54 adopts a multi-hole design to ensure that the liquid evenly covers the surface of the paper tube, simulating a real humidity environment.

[0029] The hose 51 is embedded and fixedly mounted on the mounting base 1. This arrangement prevents the hose from getting tangled or interfering, and ensures smooth movement of the spray pressing mechanism.

[0030] The spray pressing mechanism also includes a mounting plate 55 fixedly connected to the bottom of the water pump 52. A cylinder 56 is fixedly connected to the bottom of the mounting plate 55, and a pressure plate 57 is fixed to the output end of the cylinder 56. The cylinder 56 drives the pressure plate 57 to press down, and the pressure is adjustable, suitable for moisture resistance testing of paper tubes of different specifications.

[0031] The fixing mechanism includes a pair of rectangular plates 61 fixedly connected to the vertical sidewalls of the carrier 6. The two rectangular plates 61 are rotatably connected to the same bidirectional lead screw 62 on opposite sidewalls. By rotating the screw block 66, the clamping plates 65 on both sides can be adjusted synchronously, achieving quick clamping / loosening and convenient operation. A pair of connecting plates 63 are threaded onto the bidirectional lead screw 62. A transmission rod 64 is fixedly connected to the top of the connecting plate 63, and a clamping plate 65 is fixedly connected to the transmission rod 64. Anti-slip pads can be added to the contact surface between the clamping plate 65 and the paper tube to prevent damage to the paper tube surface and enhance fixing stability.

[0032] One end of the bidirectional lead screw 62 extends to the opposite sides of two rectangular plates 61 and is fixedly connected to a screw block 66. The connecting plate 63 and the carrier 6 are horizontally slidably connected.

[0033] The mounting base 1 is fixedly connected to a base 7 at its bottom, and four support legs 8 are fixedly connected to the bottom of the base 7. The four support legs 8 enhance the overall stability and reduce vibration interference during the testing process.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] First, place the paper tube to be tested horizontally on the carrier 6, rotate the screw block 66 of the bidirectional lead screw 62 to drive the two connecting plates 63 to move towards each other, and drive the clamping plate 65 to clamp the two ends of the paper tube through the transmission rod 64.

[0036] Start motor 3 to drive screw 2 to rotate, so that screw block 4 drives the spray pressing mechanism to move directly above the part of the paper tube to be tested.

[0037] Turn on the water pump 52 to pump the liquid in the storage tank 5 into the storage box 53 through the hose 51, and spray the liquid evenly onto the surface of the paper tube by the spray head 54 to simulate the humidity environment.

[0038] Then, cylinder 56 pushes pressure plate 57 down, so that the paper tube undergoes a constant pressure test in a damp state.

[0039] During the test, the horizontal position of the spray pressing mechanism can be adjusted via motor 3 to achieve multi-point detection. After the test is completed, cylinder 56 resets, and the reverse rotation of the screw block 66 releases the clamp, allowing the paper tube to be removed to observe its moisture deformation.

[0040] The device is kept stable by the base 7 and the legs 8, and the embedded design of the hose 51 ensures smooth movement.

[0041] This process enables automated pressure testing of paper tube humidity tolerance, is easy to operate, and yields repeatable data.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
