Description

Technical Field

[0001] The present invention relates to the technical field of belt detection, and particularly to a belt detection device and a detection method. Background Art

[0002] Belts are usually processed by patent leather technology, and it is necessary to detect their wear conditions before leaving the factory. At present, the folding resistance testing machine in the standard QB / T5246-2018 "Dynamic Folding Resistance Test Method for Leather Belt Products" is used for multiple folding tests to test the fatigue degree of the belt's resistance to folding. This detection method detects by folding the belt into a "ji" shape, mainly examining the crack situation of the patent leather when the belt is folded. However, in actual use, the belt is wound around the human waist, and it is difficult to form a bending situation similar to a "ji" shape. Usually, due to the movement of the belt, its bottom surface will rub against the waistband and cause wear. In addition, due to the deformation of the waistband, the belt loops will squeeze the upper edge of the belt and cause the belt to deform. Obviously, the existing detection standards cannot effectively detect the wear condition of the belt in the above situations, and lack guiding significance for practical applications.

[0041] See also Figure 1 , Figure 1The structure top view of the embodiment 1 of a belt detection device provided by the present invention is shown, which includes a belt fixing part, a test bench, a trouser waist 30, a belt 50, a fixed pressing block 32 and an anti-wear wheel 41.

[0042] The belt fixing member is fixedly connected to both ends of the belt 50 to tighten the belt 50 and drive the belt 50 to reciprocate in a first horizontal direction. Specifically, the belt fixing member includes a first slide rail 11, a first clamping block 12, a second slide rail 13, and a second clamping block 14. The first slide rail 11 and the second slide rail 13 are arranged opposite to each other and fixed on a base (the base here can be a machine fixed to the ground) at a certain distance. The first clamping block 12 and the second clamping block 14 are slidably arranged on the first slide rail 11 and the second slide rail 13 respectively, and move in the first direction along the tracks on the first slide rail 11 and the second slide rail 13 through the action of a motor or an air pump, etc. The first direction is as follows: Figure 1 Left and right directions shown.

[0043] The first slide rail 11 and the second slide rail 13 have the same structure, and a track is provided in the middle thereof for the first clamping block 12 and the second clamping block 14 to slide. The first clamping block 12 and the second clamping block 14 have the same structure, such as Figure 4 As shown, it includes a dynamic clamping block located on the upper side and a static clamping block located on the lower side. The surfaces facing each other between the dynamic clamping block and the static clamping block are clamping surfaces. The clamping surfaces are provided with a serrated structure to strengthen the bite force on the belt 50 and prevent the belt 50 from falling off. The dynamic clamping block is moved by the action of a motor or an air pump provided on the first clamping block 12 or the second clamping block 14 to clamp the belt 50.

[0044] After the first clamping block 12 and the second clamping block 14 clamp the belt 50 , the belt 50 needs to be tensioned, which can be achieved by moving and adjusting the relative positions of the first clamping block 12 and the second clamping block 14 on the first slide rail 11 or the second slide rail 13 .

[0045] The test bench is located between the two ends of the belt 50 and reciprocates in a second direction that is horizontally perpendicular to the first direction. Specifically, the test bench includes a platform 21, a third slide rail 22 and a slider 23. In this embodiment, a platform 21 and three third slide rails 22 and sliders 23 are provided. The three third slide rails 22 are arranged between the first slide rail 11 and the second slide rail 13 at a certain distance and fixed on the base. The three sliders 23 are respectively slidably arranged on the third slide rails 22 and move in the second direction along the track on the third slide rail 22 through the action of a motor or an air pump, etc. The second direction is as follows: Figure 1 Up and down directions shown.

[0046] A track for sliding the slider 23 is provided in the middle of the third slide rail 22. The slider 23 is fixed to the bottom of the platform 21 by welding or screwing, so that the platform 21 is located above the slider 23. The movement of the slide rail 23 on the third slide rail 22 can drive the platform 21 to move in the second direction.

[0047] The trouser waistband 30 is fixed on the surface of the test bench and is provided with a plurality of trouser loops 31. Specifically, in this embodiment, the structure of the trouser waistband 30 is as follows: Figure 3 As shown in FIG. 1 , it includes a detection portion supported by a plurality of different fabrics, and each detection portion is provided with a plurality of pairs of trouser loops 31. Figure 3 As shown, the waistband 30 comprises a first detection part 301, a second detection part 302, and a third detection part 303, wherein the first detection part is made of wool, the second detection part is made of polyester, and the third detection part is made of denim. The fabric of the trouser loop 31 on each detection part is consistent with the fabric used in the detection part where it is located.

[0048] The waistband 30 is fixed to the platform 21 by a fixed pressing block 41. Specifically, the fixed pressing block 41 can reciprocate in the vertical direction through the action of a motor or an air pump. When it descends, it can press against the waistband 30 on the platform 21, thereby fixing the waistband 30 on the platform 21 without causing it to move.

[0049] In another embodiment, a plurality of test benches are provided, and the structure of each test bench includes a platform 21, a third slide rail 22 and a slider 23. The test benches are provided between the first slide rail 11 and the second slide rail 12, and the slide rail 23 on each test bench can move independently. A trouser waist 30 is fixed on the platform 21 of each test bench, and the fabrics used for the trouser waists 30 on different platforms 21 are different. Similar to the structure of each detection part of the trouser waist 30 in the previous embodiment, a plurality of pairs of trouser loops 31 are provided on each trouser waist 30. The platform 21 is driven to move by the slider 23, and the movement direction of each trouser waist 30 can be independently controlled, which can complicate the folding of the trouser loops 31 and the edge of the belt 50, and more effectively simulate the actual use.

[0050] In particular, in the above two embodiments, no matter it is a whole waistband 30 or a waistband 30 disposed on several unconnected platforms, the trouser loops 31 disposed thereon can be discussed as a whole. The above trouser loops 31 are all located between the first slide rail 11 and the second slide rail 13, and the trouser loops 31 are all disposed in pairs, wherein the spacing between the pair of trouser loops 31 in the middle position is smaller than the spacing between the other pairs of trouser loops 31, specifically, the spacing between the pair of trouser loops 31 in the middle position is set in a range of 7-10 cm, and the spacing between the other pairs of trouser loops 31 is set in a range of 16-18 cm, so as to simulate the position setting of the trouser loops 31 on the actual waistband 30 as much as possible.

[0051] In addition, anti-wear wheels 41 are provided on the two side edges in the first direction of the platform 21 , and the bottom surface of the belt 50 contacts the anti-wear wheels 41 . The anti-wear wheels 41 can prevent the bottom surface of the belt 50 from scratching the edge of the platform 21 .

[0052] In addition, the present invention also provides embodiment 2, and its specific structure is as follows Figure 2 As shown, based on the above-mentioned embodiment 1, a shooting component 61 and a display component 62 as well as several groups of motors, air pumps and control units are further provided.

[0053] The photographing component 61 is fixedly arranged above the trouser waist 30 and is in communication connection with the display component 62. Specifically, it is a camera, which is controlled by the control unit to photograph the trouser waist 30 at regular intervals or in real time, and transmit the image information to the display component 62. The main body of the display component 62 is a display screen, which can display the image captured by the photographing component 61 for the staff to observe.

[0054] The motor, air pump, etc. are used to control the moving parts in the belt detection device, such as the first clamping block 12, the second clamping block 14, the sliding block 23, the fixed pressing block 42, etc.

[0055] The control unit is used to control the operation of the motor, the air pump, the shooting component 61 and the display component 62.

[0056] The present invention further provides a belt detection method, which is based on the belt detection device provided in the above-mentioned embodiment 1 or embodiment 2, and specifically includes the following steps:

[0057] Step 1, fix the waistband 30 on the surface of the test bench;

[0058] Step 2: Pass the belt 50 to be tested through the trouser loop 31 on the trouser waist 30 and then fix and tighten it with the belt fixing piece;

[0059] Step 3, fix the test bench, drive the belt 50 to reciprocate in the first direction, and detect the wear of the bottom surface of the belt 50 and the surface of the trouser waist 30;

[0060] Step 4: Fix the belt fixing member, drive the trouser waistband 30 to reciprocate in the second direction, and test the folding conditions of the two side edges of the belt 50 and the trouser loops 31.

[0061] In the above detection method, there are two parts of detection, one is the detection of the wear condition of the bottom surface of the belt 50, and the other is the detection of the folding condition of the two side edges of the belt 50. The detection of each part can simulate the actual use of the belt 50 by controlling the reciprocating motion of the moving parts, and then obtain the corresponding detection results through manual observation.

[0062] The present invention provides a belt detection device and detection method. By fixing a trouser waist 30 on a test bench, passing a belt 50 through a trouser loop 31 on the trouser waist 30, and utilizing the reciprocating motion of the belt fixing member and the test bench in a first direction and a second direction, the left-right movement of the belt 50 when worn and the folding of the trouser loop 31 on the edge of the belt 50 can be simulated, thereby effectively simulating the wear that may occur during the actual use of the belt 50 and providing a more instructive detection result.

[0063] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
