DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] like Figure 1-8 The present invention shows a strip sample sampling device for fabric testing described in this embodiment, through which a strip sample with a certain length and width can be obtained. Through the strip sample, the tensile strength test of the fabric can be completed. The sampling device includes a base 1, a pressing plate 2, a driving arm 3, and a cutting device. Among them, the pressing plate 2 has a preset weight, and has a length extending along the first direction and a width extending along the second direction. The pressing plate 2 is arranged above the base 1 and is movably arranged up and down relative to the base 1. Specifically, at least two groups of columns 12 are installed in parallel on the base 1. The top of the column 12 forms a free end. A third sleeve 24 is installed on the pressing plate 2 corresponding to the column 12. The third sleeve 24 is sleeved on the column 12 through the free end of the column 12, so that it can be slidably connected with the column 12 up and down, so that the pressing plate 2 can move up and down relative to the base 1. The fabric is placed between the base 1 and the pressing plate 2. When the pressing plate 2 is pressed down, the material can be pressed and fixed on the surface of the base 1 by the gravity of the pressing plate 2 itself, so as to facilitate the subsequent cutting operation. A plurality of jacking positions 21 are formed on the bottom surface of the pressing plate 2.

[0030] The pressing plate 2 is made of a steel plate. To increase the weight of the pressing plate 2, a counterweight 26 is arranged on the pressing plate 2.

[0031] In this embodiment, the aforementioned columns 12 are arranged on the same side of the base 1, so that an inlet and outlet are formed between the base 1 and the side of the pressing plate 2 away from the columns 12. The fabric can enter between the base 1 and the pressing plate 2 through the inlet and outlet, so as to facilitate the feeding of the fabric between the pressing plate 2 and the base 1, and facilitate the adjustment of the cutting position of the fabric between the pressing plate 2 and the base 1.

[0032] The aforementioned driving arm 3 has a designed length, and is hinged to the base 1 through a hinge seat, so that the driving arm 3 has an abutting end 32 and a pressing end 31 that move up and down around the hinge position. The number of the abutting ends 32 corresponds to the number of the aforementioned lifting positions 21. The abutting end 32 and the pressing end 31 are arranged on opposite sides of the hinge position of the driving arm 3, so that when the pressing end 31 moves downward, the abutting end 32 is driven to move upward. The aforementioned abutting end 32 is in abutment and cooperation with the lifting positions 21 of each corresponding position. Through the above-mentioned structural design, when the pressing end 31 of the driving arm 3 is pressed down, the pressing plate 2 can be lifted up, thereby driving the pressing plate 2 to move upward to move away from the base 1. In this embodiment, in the specific structural design, the force arm length from the pressing end 31 to the hinge position of the driving arm 3 is greater than the length from the abutting end 32 to the hinge position of the driving arm 3, so that the pressing plate 2 can be easily lifted up by the driving arm 3, which plays a labor-saving role. A pressing handle 311 is installed on the driving arm 3 at the pressing end 31 , and the pressing end 31 of the driving arm 3 can be easily pressed down by holding the pressing handle 311 .

[0033] In this embodiment, the aforementioned cutting device is movably mounted on the pressing plate 2 along the first direction, and includes two groups of cutters 5. The two groups of cutters 5 are arranged side by side in the second direction, and a cutting distance is formed between them. The cutting distance is also the width of the strip sample. The aforementioned cutter 5 has a cutting portion exposed below the bottom of the pressing plate 2. The cutting portion is a cutting edge. The cutter 5 of this embodiment is a round knife. An avoidance groove 11 is arranged on the aforementioned base 1 corresponding to the cutter 5. When the pressing plate 2 presses the fabric on the base 1, the cutting portion enters the avoidance groove 11, and when the cutter 5 is pushed to move, the fabric can be cut through the cutting portion. The above-mentioned cutting device includes a push-pull handle 4. The push-pull handle 4 is formed by welding a round tube. A cross bar 42 extending along the second direction is formed on the push-pull handle 4. A first sleeve 51 is fixed to the outer shell of the cutter 5. The first sleeve 51 is slidably sleeved on the cross bar 42 and has a plurality of locking positions. A locking matching structure is arranged between the crossbar 42 and the first sleeve 51. The locking matching structure is used to lock the first sleeve 51 in the locking position or unlock it. Through the above-mentioned structural design, the position of the cutter 5 on the crossbar 42 can be adjusted, and then the size of the cutting spacing between the cutters 5 on both sides can be adjusted, and then the width size of the strip sample after cutting can be adjusted. The aforementioned locking matching structure includes a positioning hole 511, a threaded hole 43 and a threaded rod. The crossbar 42 is processed with a threaded hole 43 corresponding to each locking position. The positioning hole 511 is arranged on the first sleeve 51. In the aforementioned locking position, the threaded rod is inserted into the positioning hole 511 and the threaded hole 43, and is threadedly connected with the threaded hole 43, so as to realize the locking of the first sleeve 51 in the locking position. Among them, the base 1 is processed with an avoidance groove 11 corresponding to each locking position. In the aforementioned locking position, when the pressing plate 2 presses down the fabric, the cutter 5 enters the avoidance groove 11 at the corresponding position to perform the cutting operation.

[0034] In this embodiment, the aforementioned pressing plate 2 is provided with a cutting groove 22 extending along the first direction corresponding to the cutter 5. The cutter 5 extends into the cutting groove 22 at the corresponding position and is exposed below the bottom of the pressing plate 2. One end of the cutting groove 22 forms an open end, and an operation space 23 connected to the open end of each cutting groove 22 is processed on the pressing plate 2. The operation space 23 is arranged at the front end position of the cutting groove 22 in the first direction. The operation space 23 extends along the width direction of the pressing plate 2. The aforementioned cutter 5 moves along the first direction to have a stay state in the operation space 23. In this stay state and when the first sleeve 51 is unlocked, the cutter 5 can move back and forth in the second direction on the cross bar 42 in the operation space 23, and the position of the cutter 5 on the cross bar 42 can be adjusted by the cutter 5 moving back and forth in the operation space 23. Among them, a long rod 25 extending along the first direction is fixed on the pressing plate 2 by welding. The plurality of long rods 25 are welded to the third sleeve 24. The end of the long rod 25 away from the first sleeve 51 forms a free end. A second sleeve 41 is arranged on the push-pull handle 4. The second sleeve 41 is sleeved on the long rod 25 via the free end of the long rod 25 and is connected to the long rod 25 in a sliding fit. By moving the second sleeve 41 on the long rod 25, the push-pull handle 4 and the cutter 5 can move along the first direction. In addition, by rotating and raising the position of the cutter 5, the push-pull handle 4 and the cutter 5 can be moved out of the free end of the long rod 25 as a whole.

[0035] When in use, the pressing end 31 of the driving arm 3 is pressed down to lift the pressing plate 2 upward. Insert the fabric between the pressing plate 2 and the base 1, release the pressing end 31 of the driving arm 3, and the pressing plate 2 uses its own gravity to press and fix the fabric on the base 1. Push the handle to drive the two cutters 5 to move and cut along the cutting groove 22 synchronously to cut the strip sample of preset length and width, and finally use scissors to cut the root of the cut strip sample, so as to realize the sampling operation of the strip sample of the fabric. After the above operation is completed, press the pressing end 31 of the driving arm 3 again to lift the pressing plate 2, adjust the cutting position of the fabric between the pressing plate 2 and the base 1, and release the pressing end 31 of the driving arm 3 so that the strip sample can be cut again. The above operation is convenient, the length and width of the strip sample are accurate and consistent, and the batch sampling operation of the strip sample of the fabric can be quickly realized, which saves time and effort and effectively meets the detection requirements of polyester fabrics. In addition, according to actual needs, by moving the cutter 5 to different locking positions and locking them, the cutting interval between the two cutters 5 can be adjusted to meet the sampling operation of strip samples of different widths.
