Description

Technical Field

[0001] This utility model belongs to the field of fabric pilling comparison testing technology, and in particular relates to a fabric pilling comparison testing device. Background Technology

[0002] In the production process, after the fabric is spun into fabric blanks by textile and other equipment, in order to ensure the quality of the fabric, it is often necessary to test the produced fabric during the production process. The tests include tensile strength test, abrasion resistance test, shrinkage test and pilling test.

[0003] The pilling test is used to determine whether and how severe the pilling occurs when the fabric is rubbed over a long period of time, in order to assess the effectiveness of the fabric's weaving process.

[0004] The current testing method involves the workshop taking fabric samples and sending them directly for testing. However, in actual production, because the production equipment runs continuously, many batches of fabric are produced daily, necessitating timely submission for testing and obtaining test reports. Furthermore, due to the large number of fabric batches produced, each batch requires sampling and testing according to production requirements.

[0005] Therefore, in actual production, the method of sending the fabric for testing and obtaining the test report cannot meet the production needs. This is reflected in the fact that once the fabric is found to be substandard in the test, the equipment in the production workshop has already produced a large number of substandard batches of fabric.

[0006] Therefore, in the actual production process, if a simple testing device can be used to quickly test the fabrics produced on multiple production lines in the workshop, and evaluate the quality of the fabric production in a highly intuitive way, it can not only ensure a high pass rate of the produced fabrics and reduce the probability of scrap rate, but also detect unqualified fabrics in a timely manner and troubleshoot the equipment.

[0007] Comparative testing is a method that simultaneously compares experimental fabrics with qualified fabrics. It offers advantages such as fast testing speed, high accuracy, and the ability to promptly intervene in production equipment when unqualified fabrics are detected. Therefore, it is widely used in workshop production processes, such as for fabric tensile comparison tests and abrasion resistance comparison tests.

[0008] However, there is currently no rapid testing device for detecting pilling in fabrics during workshop production. Utility Model Content

[0009] Based on the above background, the purpose of this utility model is to provide a fabric pilling comparison test device.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A fabric pilling comparison test device includes a bottom support, a plurality of adjustable columns are installed on the top of the bottom support, and test brackets are symmetrically arranged vertically and vertically connected between the adjustable columns; friction test pads are detachably installed on the test brackets.

[0012] It also includes a friction test assembly that works with the test bracket. The friction test assembly includes a rotating bracket with several sample mounting structures that work with the friction test pieces. After the test fabric is mounted and fixed by the sample mounting structures, it is tested for pilling by friction with the friction test pieces.

[0013] The rotating bracket is driven to rotate by a motor.

[0014] Preferably, a first test bracket and a second test bracket, symmetrically arranged vertically, are assembled and connected between the adjusting columns;

[0015] The first test bracket and the second test bracket are each integrally formed with a plurality of protrusions that slide to connect and adjust the columns;

[0016] The upper and lower sides of the adjusting column are respectively threaded with push nuts that push the first test bracket and the second test bracket to abut against the test bracket.

[0017] Preferably, the friction test piece is annular in shape;

[0018] Several short mounting screws are fixedly connected to the outer edge and inner edge of the first test bracket and the second test bracket, respectively. Several through holes are opened on the outer edge and inner edge of the friction test piece. The short mounting screws pass through the through holes and are threaded with locking nuts to lock the friction test piece.

[0019] Preferably, the friction test piece is abrasive paper.

[0020] Preferably, the rotating support includes a central rotating seat;

[0021] The outer wall of the central rotating seat is detachably equipped with several mounting brackets for mounting the sample structure.

[0022] The sample loading structure is installed on the outside of the mounting bracket.

[0023] Preferably, the sample loading structure includes a sample loading seat installed on the top of the mounting bracket and cooperating with the first test bracket, and a sample loading seat installed on the bottom of the mounting bracket and cooperating with the second test bracket;

[0024] The outer wall of the upper sample holder is threaded with a retaining ring. After the test fabric is placed in the upper sample holder, the edge of the test fabric is locked between the retaining ring and the outer wall of the upper sample holder by the retaining ring.

[0025] Preferably, the mounting bracket has a mounting hole, and a threaded sleeve is fixedly installed in the mounting hole;

[0026] The upper sample holder is fixedly connected to a stud that is threaded onto a threaded tube sleeve.

[0027] Preferably, the inner ends of the mounting bracket are integrally formed with first mounting seats on both sides, and the outer side of the central rotating seat is fixedly connected with a second mounting seat, and the first mounting seat and the second mounting seat are fastened together by bolts.

[0028] Preferably, the motor is fixedly mounted at the top position of the bottom bracket;

[0029] A long drive shaft is fixedly mounted on the output shaft of the motor, and the long drive shaft is fixedly mounted on the central rotating seat.

[0030] Preferably, a plurality of rotating connecting brackets with rotating connecting long drive shafts are fixedly installed on the adjusting column;

[0031] The rotating connecting bracket is equipped with a bearing, and the long drive shaft is rotatably connected to the bearing.

[0032] This utility model has the following beneficial effects:

[0033] 1. During the testing process, first adjust the first and second test brackets to move closer to the sample structure to facilitate testing. Then, hold the first and second test brackets in position by turning the push nuts until they respectively abut against the top of the first test bracket and the bottom of the second test bracket. Friction test pads are detachably mounted on the test brackets.

[0034] The above method enables rapid testing by quickly adjusting the first and second test brackets to simultaneously contact the fabric after the fabric sample is loaded, while in traditional testing methods, each test unit requires the installation of a friction pad, which is very cumbersome.

[0035] 2. The sample loading structure includes a sample holder mounted on the top of the mounting bracket and mating with the first test bracket, and a sample holder mounted on the bottom of the mounting bracket and mating with the second test bracket (the cross-sectional shape of the sample holder is annular). A retaining ring is threaded onto the outer wall of the sample holder (the inner wall of the retaining ring and the outer wall of the sample holder have mating threads). During sample loading, the fabric is secured by the retaining ring, making the loading method simple and fast. Simultaneously, this structure allows two test fabrics to be loaded onto one test site at the same time, enabling the entire device to test a larger number of fabric samples in a single experiment.

[0036] 3. This method enables comprehensive and rapid comparative testing of a large number of batches of fabric produced in the production workshop, using a relatively accurate, efficient, and simple testing operation. It allows for the timely identification of substandard fabrics (severe pilling) and prompt troubleshooting of production equipment, preventing significant economic losses from large quantities of defective fabrics.

[0048] Example 1

[0049] like Figure 1-6 As shown, a fabric pilling comparison test device includes a bottom support 4, and a plurality of circumferentially distributed adjustment columns 5 are installed on the top of the bottom support 4. The adjustment columns 5 have a threaded structure.

[0050] Meanwhile, test brackets are symmetrically arranged at the top and bottom of the adjusting columns 5; specifically, the upper end is the first test bracket 1, and the lower end is the second test bracket 2.

[0051] The first test bracket 1 and the second test bracket 2 are ring-shaped structures made of stainless steel plates.

[0052] Meanwhile, in order to achieve friction testing between the first test bracket 1 and the second test bracket 2 and the sample structure below during the test, the first test bracket 1 and the second test bracket 2 are designed to be locked after sliding adjustment.

[0053] Specifically, the first test bracket 1 and the second test bracket 2 are each integrally formed with a number of sliding connection adjustment columns 5 protrusions; the upper and lower sides of the adjustment columns 5 are respectively threaded with push nuts that push the first test bracket 1 and the second test bracket 2 to abut against the test bracket.

[0054] During the test, the first test bracket 1 and the second test bracket 2 are first adjusted to move closer to the sample structure to facilitate testing with the sample structure. Then, the first test bracket 1 and the second test bracket are kept in position by turning the push nut until it abuts against the top of the first test bracket 1 and the bottom of the second test bracket 2, respectively.

[0055] According to the existing friction pilling test, the above-mentioned test bracket is detachably equipped with a friction test piece 3 (which adopts the conventional test principle of friction test for existing fabric pilling test).

[0056] Specifically, the friction test piece 3 is ring-shaped; several short mounting screws 31 are fixedly connected to the outer edge and inner edge of the first test bracket 1 and the second test bracket 2, and several through holes are opened on the outer edge and inner edge of the friction test piece 3. The short mounting screws 31 pass through the through holes, and a locking nut for locking the friction test piece 3 is threaded onto the short mounting screws 31.

[0057] Before testing, the friction test piece 3 is installed on the first test bracket 1 and the second test bracket 2. After installation, the locking nut is tightened.

[0058] During the test, the sample fabric is subjected to friction test piece 3 (friction test piece 3 is a conventional test surface used for existing fabric friction pilling tests, such as sandpaper or fabric with high friction).

[0059] Example 2

[0060] like Figure 1-6 As shown, this embodiment, based on the structure of Embodiment 1, improves upon the following to simultaneously test different batches of fabric produced on multiple production lines, following the principle of controlled experimental testing: qualified fabric and fabric from the production batch are simultaneously sampled and tested. The present invention makes the following improvements:

[0061] It also includes a friction test assembly that works with the test bracket. The friction test assembly includes a rotating bracket. The specific structure of the rotating bracket is as follows: the rotating bracket includes a central rotating seat 71; the outer side wall of the central rotating seat 71 is detachably equipped with several mounting brackets 72 for mounting the sample structure; the outer end of the mounting bracket 72 is equipped with the sample structure 73.

[0062] The test fabric and the qualified fabric of the control sample are simultaneously sampled on the sample structure 73.

[0063] Specifically, the sample mounting structure 73 includes a sample mounting seat that is installed on the top of the mounting bracket 72 and cooperates with the first test bracket 1, and a sample mounting seat 731 that is installed on the bottom of the mounting bracket 72 and cooperates with the second test bracket 2 (the cross-sectional shape of the sample mounting seat 731 is annular).

[0064] Meanwhile, the outer side wall of the upper sample holder 731 is threadedly connected to a ferrule 732 (the inner side wall of the ferrule 732 and the outer side wall of the upper sample holder 731 have a threaded structure that mates).

[0065] During the sample loading process, the operator first prepares a fabric sample according to the size of the sample holder 731 (the fabric sample is also in the shape of a round piece, and its size is larger than that of the sample holder 731). The round piece of fabric sample is placed on the sample holder 731. Then the operator tucks the edge of the fabric towards the side wall of the sample holder 731 to keep the fabric test friction surface flat and fully tensioned on the sample holder 731.

[0066] The locking ferrule 732 is then threaded onto the sample holder 731. Because the fabric is relatively thin, the ferrule 732 can smoothly connect to the sample holder 731 and press the fabric threads against it (under the pressure of the ferrule 732, the fabric deforms and gets into the threaded groove). Simultaneously, the sample holder 731 has an integrally formed annular flange 7311 corresponding to the ferrule 732. After the ferrule 732 clamps the fabric, it abuts against the annular flange 7311.

[0067] Therefore, in actual operation, in order to prevent the fabric from coming loose, the fabric disc is tucked and attached to the side of the upper sample holder 731 (at this time the fabric shape is similar to a cylindrical structure), and the bottom edge of the fabric is attached to the annular flange and pressed down by the retaining ring 732. This method ensures the stability of the fabric feeding and prevents the fabric from coming loose.

[0068] The above method enables the simultaneous sampling of both production and experimental fabrics.

[0069] Because the above structure allows for the placement of a fabric disc sample at both the top and bottom of each mounting bracket 72, it enables the testing of multiple samples in a single operation. This method not only improves testing efficiency but also allows for rapid fabric sample loading and testing.

[0070] The reason is that after the sample fabric is applied, the upper and lower test brackets can be quickly adjusted and tested in the manner described above.

[0071] During the test, the sample holder 731 rubs against the fabric at the center of the annular friction test piece 3, and maintains a safe distance from the short mounting screws 31 fixedly installed on both sides of the friction test piece 3.

[0072] After testing for a period of time, such as 30 minutes as required, the upper and lower test supports can be quickly separated and the test fabric removed for comparison with the qualified control fabric.

[0073] This approach allows for precise, efficient, and simple testing of a large number of batches of fabric produced in the production workshop within a short period. It also enables timely identification of substandard fabrics (such as those with severe pilling) and prompt removal of debris from malfunctioning production equipment, preventing significant economic losses from a large number of defective batches.

[0074] Example 3

[0075] like Figure 1-6 As shown, in this embodiment, based on the structure of Embodiment 1, the mounting bracket 72 has mounting holes, and a threaded tube sleeve is fixedly installed in the mounting holes; a stud 733 threaded to the threaded tube sleeve is fixedly connected to the sample holder 731. This method allows the sample structure 73 to be installed on the top and bottom of the mounting bracket 72, thereby increasing the amount of fabric sample tested.

[0076] The upper mounting bracket 72 is detachably installed as follows: the inner ends of the mounting bracket 72 are integrally formed with first mounting seats on both sides, and a pair of second mounting seats are fixedly connected to the outer side wall of the central rotating seat 71 (the second mounting seats are fixedly installed on the outer side wall of the central rotating seat 71 by mounting rods), and the first mounting seats and the second mounting seats are fastened together by bolts.

[0077] The sample loading structure 73 can be replaced in a detachable manner, such as by replacing it with a larger sample loading seat 731.

[0078] The rotating bracket is driven to rotate by a motor 74. Specifically, following the existing motor 74 drive rotation connection method, the motor 74 is fixedly installed at the top center position of the bottom bracket 4. At the same time, a long drive shaft is fixedly installed on the output shaft of the motor 74, and the long drive shaft is fixedly installed at the center position of the central rotating seat 71.

[0079] Meanwhile, a pair of rotating connecting brackets 6 with vertically spaced rotating connecting long drive shafts are fixedly installed on the adjusting column 5; according to the existing method, bearings are installed on the rotating connecting brackets 6, and the long drive shafts are rotatably connected to the bearings.

[0080] This method increases the stability of the rotating drive bracket 6.

[0081] The aforementioned motor 74 drives the rotating bracket to rotate, and the rotating connecting bracket that increases the rotational stability of the long drive shaft is a conventional design in the prior art.

[0082] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
