Description

Technical Field

[0001] The utility model relates to the technical field of fabric testing devices, and particularly relates to a wear resistance testing device for wear-resistant fiber fabrics. Background Technique

[0002] With the development of technology, people have more requirements for various properties of fabrics. There are a variety of functional fabrics such as wear-resistant fabrics. After the wear-resistant fabrics are produced, it is necessary to test their wear resistance to compare and improve different processes or formulas. The wear resistance of fabrics refers to the durability of fabrics under the action of friction, scratching, etc. Generally, the fabric is rubbed with a friction mechanism, and the weight or appearance of the fabric before and after is recorded to evaluate the wear resistance of the fabric.

[0003] However, most of the existing testing devices adopt an open structure. Although it is convenient to disassemble and replace the fabric inside from all aspects, it will also cause problems such as fiber dust scattering everywhere, and it is not convenient for internal temperature control. But if a dust-proof structure is added, due to the small volume of the testing device, when disassembling and replacing the fabric, it is necessary to reach into the inside of the testing body, and this single-disassembly method is not convenient for batch testing work. A lot of time is required for loading, unloading and adjustment between the front and back fabrics, and the efficiency is low. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wear resistance testing device for wear-resistant fiber fabrics, which can prevent fibers or dust from flying outwards during the testing process of the testing device, improve cleanliness and safety, facilitate external environmental protection and internal temperature control, etc. At the same time, it takes into account the convenience of loading, unloading and material changing work after the testing is completed inside the testing mechanism, and improves the efficiency of batch detection.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A wear resistance testing device for wear-resistant fiber fabrics includes a testing body. An opening and closing door is provided on one side of the testing body. An upper template and a lower template are provided inside the testing body. A plurality of rows of sliding rails are connected below the upper template. One end of the sliding rail is far from the opening and closing door, and the other end is close to the opening and closing door and is provided with a locking member. The mounting plate slides into the sliding rail from the outer end and is limited by the locking member. A plurality of testing heads are provided below the mounting plate, and corresponding friction heads are provided on the lower template. The testing heads clamp the fabric, and the upper template reciprocates horizontally inside the testing body to drive the fabric to reciprocally rub against the friction heads.

[0007] Furthermore, the sliding rails are paired and symmetrically arranged, including side plates and rail bodies. The mounting plate is located between the two side plates, and both sides are respectively abutted against the upper side of the rail bodies.

[0008] Furthermore, the locking member includes a limiting weight block which is slidably connected up and down in the upper template. The lower limit point of the sliding of the limiting weight block is blocked on the sliding path of the corresponding mounting plate, and the upper limit point is away from the sliding path of the corresponding mounting plate.

[0009] Furthermore, the test head is detachably connected to the lower part of the mounting plate.

[0010] Furthermore, a plurality of adjusting screws are connected to the lower part of the mounting plate, and the test head is threadedly connected to the lower end of the adjusting screw.

[0011] Furthermore, the friction head is detachably connected to the lower template.

[0012] Furthermore, the lower template is detachably connected to the test body. A plurality of fixing screws are connected to the outside of the lower template. After passing through the lower template downward, the fixing screws are threadedly connected to the test body.

[0013] Furthermore, the upper template is driven to move reciprocally by a driving member. The driving member includes a turntable which is driven to rotate by a motor. A vertical eccentric rod is connected to one side of the turntable, and the other end of the eccentric rod is connected to the upper template.

[0014] In summary, the utility model has the following beneficial effects:

[0015] The arrangement of the opening and closing door can prevent fibers or dust from flying out during the testing process of the testing device, improve cleanliness and safety, and facilitate the testing of the wear resistance of fabrics at different temperatures through the temperature control system. At the same time, the mounting plate is installed conveniently and quickly through the guidance of the slide rail and the self-weight limit of the limiting weight block. Multiple test heads are installed on the mounting plate at one time. After the fabric test is completed, the next batch of test fabrics can be replaced directly by replacing the mounting plate. Compared with reaching into the deep part of the test body to disassemble and replace, it greatly improves the convenience of the loading, unloading and material changing work after the internal test of the test mechanism is completed, as well as the efficiency of batch detection.

Specific embodiments

[0020] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings. This embodiment does not constitute a limitation to the present invention. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of this application.

[0021] A wear resistance testing device for wear-resistant fiber fabrics, as Figure 1 shown, includes a test body 1. On one side of the test body 1, there is an opening and closing door 11 for opening and closing the inside of the test body 1 for testing, and preventing sundries such as fibers or dust generated during the test from scattering outside the test body 1, and to a certain extent reducing the working noise and protecting the stability of the working environment. A dust collection device can be set inside the test body 1, or it can be connected to a temperature control device to control the temperature inside the test body 1 to help test the wear resistance under different temperature conditions.

[0022] As Figure 2 and Figure 3 shown, inside the test body 1, there are an upper template 2 and a lower template 3. The upper template 2 is used to connect several test heads 41. There are corresponding friction heads 31 on the lower template 3. The test heads 41 clamp the fabric. The upper template 2 as a whole horizontally reciprocates inside the test body 1 through a driving member, driving the fabric to reciprocally rub against the friction heads 31. The upper template 2 and the lower template 3 can also be arranged upside down.

[0023] In this embodiment, the driving member includes several turntables 5. At least one turntable 5 is driven to rotate by a motor. At the same position on one side of each turntable 5, there is a vertical eccentric rod 51 connected. The other end of the eccentric rod 51 is connected to the upper template 2, used to drive the upper template 2 as a whole to reciprocate, or support the upper template 2 to achieve reciprocal circular rubbing between the fabric and the friction heads 31.

[0024] The turntable 5 and the eccentric rod 51 can be connected to the top of the upper template 2 or supported below the upper template 2 (replacing the rear test head 41 and the friction head 31 to make way). The two sides of the turntable 5 are respectively connected to the eccentric rod 51 and the central rotating shaft. The central rotating shaft is fixed in the testing machine body through bearings, and one of the central rotating shafts is driven to rotate by a motor. The lower part of the upper template 2 can also be supported on the horizontal plane of the testing machine body 1 through structures such as balls to provide support and reduce friction. The driving member can also be replaced with a horizontal linear module or a linear driving device such as a hydraulic cylinder. By driving the upper template 2 to reciprocate horizontally, the wear resistance test can be realized.

[0025] Among them, how the test head 41 clamps the fabric and how the friction head 31 clamps the friction surface belong to the prior art and will not be elaborated here. For example, the fabric is padded on the back by a sponge and then fixed by a pressing ring around it, and the friction surface is fixed by a pressing ring.

[0026] As Figure 2 shown, several columns of slide rails 21 are connected below the upper template 2. One end of the slide rail 21 is far from the opening and closing door 11, and the other end is close to the opening and closing door 11 and is provided with a locking member. The mounting plate 4 slides into the slide rail 21 from the outer end and is limited by the locking member. Several test heads 41 are connected below the mounting plate 4.

[0027] In this embodiment, the slide rails 21 are arranged in pairs and symmetrically, including side plates and rail bodies fixed to the inner side of the bottom of the side plates, in an L shape. The mounting plate 4 is located between the two side plates, and the two lower sides respectively abut against the upper sides of the rail bodies. The rail bodies can be anti-friction components such as balls.

[0028] The locking member includes a limiting weight 22. The limiting weight 22 is slidably connected up and down in the upper template 2, and the lower limit point of the sliding of the limiting weight 22 blocks the sliding path of the corresponding mounting plate 4, while the upper limit point leaves the sliding path of the corresponding mounting plate 4. During installation, the inner end of the mounting plate 4 is pushed upward to lift the limiting weight 22, and then inserted into the slide rail 21. After installation in place, the limiting weight 22 falls under its own weight and abuts against the outer end of the mounting plate 4. During disassembly, the limiting weight 22 is pushed upward, and then the mounting plate 4 is pulled out for replacement or disassembly and assembly.

[0029] As Figure 2 shown, the test head 41 is detachably connected below the mounting plate 4. Several adjusting screws 42 are connected below the mounting plate 4. The test head 41 is threadedly connected to the lower end of the adjusting screw 42 to control the test pressure so that the fabric is pressed against the friction head 31 with different pressures.

[0030] The friction head 31 is detachably connected to the lower template 3 for easy replacement, and it can be connected by means of threads or plugging. The lower template 3 is detachably connected to the test body 1 for easy overall replacement. In this embodiment, an insertion cylinder with an opening facing the opening and closing door 11 is connected to the inside of the test body 1, and the inside of the lower template 3 is horizontally inserted into the insertion cylinder. Several vertical fixing screws 32 are connected to the outside of the lower template 3. After passing through the lower template 3 downward, the fixing screws 32 are threadedly connected to the test body 1.

[0031] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the technical solution of the present invention.
