Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and specifically relates to a fabric stretch testing device with a quick disassembly and assembly structure. Background Technology

[0002] A fabric tensile testing device is used to evaluate the performance of fabrics under tensile conditions. It measures key indicators such as breaking strength, elongation, and elastic recovery by applying a certain tensile force. Existing fabric tensile testing devices often face the challenge of testing fabrics of varying widths, thus requiring multiple clamps of different sizes to accommodate different fabric widths. Operators can select and install the appropriate clamp according to actual needs. The advantage of this method is its targeted approach; each clamp is optimized for a specific fabric width, and because each clamp is designed for a specific width, the testing accuracy is high. However, the disadvantages of this method include the need for frequent clamp changes, increasing operation time and complexity, and requiring more storage space to store clamps of different sizes. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0006] In a preferred embodiment, the workbench is composed of a vertical plate and a horizontal plate, the vertical plate is located on the right side of the horizontal plate and is an integral structure with the horizontal plate, and a support base is provided on the left and right sides of the rear top of the workbench.

[0007] A motor is installed at the front and rear positions on the right side of the vertical plate. The two sets of motors are synchronous reverse motors. The output end of the motor on the left side is connected to a set of transmission shafts through a coupling.

[0008] In a preferred embodiment, the drive shaft is located inside the shaft hole on the side of the support base, and the left side of the drive shaft is recessed to the right to form a screw groove, and an internal thread groove is provided on the inner side of the screw groove.

[0009] In a preferred embodiment, a clamping assembly is installed between each pair of left-right opposing support bases and adjustment components. The clamping assembly has a second rotating shaft on its right side, and a connecting rod on its right side. The connecting rod has a thread on its outer side that matches the specifications of the internal thread groove.

[0010] In a preferred embodiment, the clamping assembly has a rotating shaft on the left side, which is placed inside the placement slot. The clamping assembly consists of an upper clamping member and a lower clamping member.

[0011] The upper and lower clamping components together form a cylindrical structure. The left and right sides of the upper and lower clamping components are connected and fixed by two sets of bolts. The upper and lower clamping components together form a cylindrical structure, and the surfaces of the upper and lower clamping components are bonded with rubber layers to increase the friction between them and the fabric, which facilitates the stretching of the fabric. At the same time, a pressure sensor is embedded in the curved side of the upper clamping component to monitor the tension during the fabric stretching process in real time and transmit the data to an external control terminal.

[0012] In a preferred embodiment, the horizontal structure of the L-shaped support plate has a screw hole that matches the specifications of the positioning screw.

[0026] Please see Figures 1 to 4 A fabric stretch testing device with a quick-assembly and disassembly structure includes: a workbench 100 and an adjustment component 300. The workbench 100 has an adjustment groove 110 on the left and right sides of the top front for adjusting the sliding distance of the adjustment component 300.

[0027] The adjustment assembly 300 includes a positioning screw 321 for positioning the position of the adjustment assembly 300. The top of the positioning screw 321 is provided with a knob 320. Below the knob 320 is a support plate 310 with an L-shaped structure. The upper right side of the support plate 310 is provided with a placement groove 311. Below the support plate 310 is a sliding block 312 for sliding.

[0028] The workbench 100 consists of a vertical plate and a horizontal plate. The vertical plate is located on the right side of the horizontal plate and is an integral structure with the horizontal plate. A support base is provided on the left and right sides of the rear top of the workbench 100.

[0029] A motor is installed at the front and rear positions on the right side of the vertical plate. The two sets of motors are synchronous reverse motors. The output end of the motor on the left side is connected to a set of transmission shafts 230 through a coupling.

[0030] The drive shaft 230 is located inside the shaft hole opened on the side of the support base. The left side of the drive shaft 230 is recessed to the right to form a screw groove 231, and an internal thread groove is opened on the inner side of the screw groove 231.

[0031] Between each pair of left and right opposing support bases and adjustment components 300, a clamping component 200 is installed. The clamping component 200 has a rotating shaft 220 on its right side, and a connecting rod 221 on its right side. The connecting rod 221 has a thread on its outer side that matches the specifications of the internal thread groove.

[0032] The clamping assembly 200 has a rotating shaft 210 on the left side, which is placed inside the placement slot 311. The clamping assembly 200 consists of an upper clamping member and a lower clamping member.

[0033] The upper and lower clamping components together form a cylindrical structure. The left and right sides of the upper and lower clamping components are connected and fixed by two sets of bolts. The upper and lower clamping components together form a cylindrical structure, and the surfaces of the upper and lower clamping components are bonded with rubber layers to increase the friction between them and the fabric, which facilitates the stretching of the fabric. At the same time, a pressure sensor is embedded in the curved side of the upper clamping component to monitor the tension during the fabric stretching process in real time and transmit the data to an external control terminal.

[0034] The horizontal structure of the L-shaped support plate 310 has a screw hole that matches the specifications of the positioning screw 321. Several sets of positioning holes are opened from left to right on the lower inner surface of the adjusting groove 110. The radius of the positioning screw 321 matches the radius of the positioning hole.

[0035] The longitudinal section of the adjusting groove 110 is U-shaped, and the longitudinal section of the sliding block 312 matches the shape of the longitudinal section of the adjusting groove 110. The sliding block 312 is located at the bottom of the vertical structure of the L-shaped structure of the support plate 310.

[0036] A push-pull plate 313 for the push-pull adjustment assembly 300 is provided on the upper left side of the support plate 310. The worktable 100 has scale lines at the front and rear positions of the top. The front scale line is located in front of the front adjustment groove 110, and the rear scale line is located behind the rear adjustment groove 110. Each scale line is a scale unit every 5cm. By aligning the knob 320 with the scale unit, the position of the positioning screw 321 below the knob 320 can be determined to be aligned with the positioning hole. This facilitates flexible adjustment of the distance between the adjustment assembly 300 and the support base, and also facilitates positioning the positioning screw 321 with the positioning hole. The engagement between the positioning screw 321 and the positioning hole makes it easy to fix the position of the adjustment assembly 300.

[0037] Example 1: Please refer to Figures 1 to 4In actual use, an adjustment groove 110 is provided on the front and back positions of the top left side of the worktable 100. Several sets of positioning holes are sequentially provided on the lower inner surface of the adjustment groove 110 from left to right. A scale line is provided on the top of the front adjustment groove 110 near the front side of the worktable 100. Each 5cm increment on the scale line is a graduation unit, and each graduation unit corresponds to a positioning hole. The front and back sides of the worktable 100 have identical structural specifications. An adjustment assembly 300 is provided above the adjustment groove 110. The adjustment assembly 300 includes a… An L-shaped support plate 310 has a placement groove 311 on the top of the vertical structure on the right side of the support plate 310 for placing the rotating shaft 210 on the left side of the clamping mechanism. A sliding block 312 is provided below the vertical structure. The longitudinal section of the sliding block 312 matches the longitudinal section shape of the adjustment groove 110. A screw hole is provided on the top of the horizontal structure on the left side of the support plate 310. A positioning screw 321 is provided inside the screw hole. A knob 320 is provided on the top of the positioning screw 321. A push-pull plate 313 for pushing and pulling the adjustment assembly 300 is provided on the left side of the horizontal structure.

[0038] In actual operation, firstly, place the front and back sides of the fabric on top of the lower clamping components on the front and back sides respectively. Then, pick up the two sets of upper clamping components. Each set of upper clamping components is fixed to the left and right sides of the lower clamping components with two sets of bolts, thereby clamping and fixing the front and back sides of the fabric with two sets of clamping components 200 respectively. At this time, the fabric is in a relaxed state, and the rotating shaft 210 on the left side of the lower clamping component is inside the placement groove 311. The rotating shaft 220 on the right side of the lower clamping component is threadedly connected to the screw groove 231 on the left side of the drive shaft 230 through the screw on its right side. The drive shaft 230 is inside the shaft hole opened on the side of the support base. The right side of shaft 230 is connected to the motor on the right side of the vertical plate via a coupling. Two sets of motors are started simultaneously. The two sets of motors are synchronous reverse motors (the motors are existing technology, and their internal structure and working principle will not be described here). The two sets of motors reverse, driving the two sets of clamping components 200 to reverse, thereby rotating and wrapping the fabric around the surface of the clamping components 200, and then gradually increasing the tensile force on the fabric. A pressure sensor is embedded in the curved side of the outer side of the upper clamping component, which can monitor the change of the tensile force on the fabric in real time, thereby enabling the fabric to be tensile tested (the fabric tensile testing is existing technology, and its working principle will not be described here).

[0039] After the test is completed, the fabric and the two sets of upper clamping components can be removed by reversing the above steps. Then, first, rotate the two sets of knobs 320 respectively, so that the knobs 320 drive the positioning screw 321 to rotate in the opposite direction and move upward, so that the bottom of the positioning screw 321 disengages from the positioning hole. Then, pinch the push-pull plate 313 and move it to the left. Each 5cm is a scale unit on the scale line, and the knobs 320 are opposite to each scale unit. That is, by the opposition of the knobs 320 to each scale unit, the vertical opposition of the positioning screw 321 to the positioning hole below can be determined, thereby determining the moving distance and positioning of the adjustment base. This increases the distance between the two sets of adjustment components 300 and the support base, thereby achieving adaptability to clamping components 200 of different widths. The final effect is that by moving the two sets of adjustment components 300, adaptability to clamping components 200 of different widths can be achieved, thus clamping fabrics of different widths without occupying extra space, which greatly improves the flexibility of the testing device.

[0040] Example 2: Please refer to Figures 1 to 4 When the clamping component 200 needs to be replaced, first calculate the distance that the adjusting component 300 needs to move based on the total length of the clamping component 200 to be replaced. Then, rotate the knob 320 in the reverse direction to drive the positioning screw 321 to disengage from the positioning hole. Then, move the clamping component 200 a corresponding distance according to its length and make the distance between the adjusting component 300 and the support base match. At this time, the knob 320 and the corresponding scale unit are opposite each other. Rotate the knob 320 in the forward direction to drive the positioning screw 321 to connect with the screw hole threadedly. Push the positioning screw 321 down and insert it into the positioning hole directly below it, thereby completing the adjustment of the adjusting component 300. Then, put the rotating shaft 210 on the left side of the lower clamping part into the placement groove 311. Then, hold the outside of the lower clamping part and rotate the lower clamping part in the forward direction so that the screw rod 221 on the right side of the rotating shaft 220 on the right side is threadedly connected to the screw groove 231 on the left side of the transmission shaft 230.

[0041] It should be noted that, apart from the difference in total length, the structure of each clamping component 200 is the same, and will not be described in detail here. This allows for quick disassembly and replacement of the clamping component 200. When it is necessary to replace or maintain the adjusting component 300, reverse the above steps and then pinch the push-pull plate 313 and move it to the left until the sliding block 312 is completely disengaged from the adjusting groove 110 to the left. Then the adjusting component 300 can be removed. Therefore, the final effect is to greatly improve the ease and efficiency of disassembly and assembly of the clamping component 200, and at the same time facilitate the maintenance and replacement of the adjusting component 300.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
