DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1-9An embodiment of the present invention provides a water-soluble yarn textile elasticity testing device, including a workbench 1, on which a slider 2, a movable block 3 and a two-stage driving mechanism are provided. The slider 2 is slidably connected to the workbench 1 and is used to place the textile; the movable block 3 is located above the slider 2 and is used to cooperate with the slider 2 to clamp the end of the textile; the two-stage driving mechanism has a first stroke for driving the movable block 3 to be close to the slider 2 and a second stroke for driving the movable block 3 to slide along the workbench 1 with the slider 2 to stretch the textile.

[0035] Specifically, when conducting elasticity tests on textiles, a constant force method (stretching the textile at a specified tensile force) or a fixed elongation method (stretching the textile to a specified length) is generally used to test data such as the elongation, fixed elongation force, elastic recovery rate and plastic deformation rate of the textile; when conducting elasticity tests, a stretching structure is required to apply tension to the opposite ends of the textile, thereby forcing the textile to undergo elastic deformation. The above are all existing technologies and will not be elaborated here. The innovation of the embodiment of the present invention is that a slider 2, a movable block 3 and a two-stage driving mechanism are arranged on a workbench 1, and the slider 2 is slidably connected to the workbench 1. When in use, the end of the textile can be placed on the slider 2; the movable block 3 is located above the slider 2. After the textile is placed, the first stroke of the two-stage driving mechanism can drive the movable block 3 to be close to the slider 2 to clamp and fix the end of the textile, and then the second stroke of the two-stage driving mechanism can drive the movable block 3 to slide along the workbench 1 together with the slider 2, thereby stretching the end of the textile to complete the operation of stretching the water-soluble yarn textile, and then the two-stage driving mechanism is reversed to drive the movable block 3 and other structures to reset so that the textile can shrink to complete an elasticity test. During the process, the two strokes of the two-stage driving mechanism are operated alternately in sequence, which can reduce the probability of device error and minimize the impact on the accuracy of the textile elasticity test.

[0036] An embodiment of the present invention provides a water-soluble yarn textile elasticity testing device. When in use, one end of the textile is placed on a slider 2, and then the first stroke of the two-stage driving mechanism can drive the movable block 3 to be close to the slider 2 to clamp and fix one end of the textile. Then, the second stroke of the two-stage driving mechanism can drive the movable block 3 to slide along the workbench 1 with the slider 2, so that one end of the textile is stretched by the movable block 3 and the slider 2, thereby completing the elasticity test of the water-soluble yarn textile. During the process, the two strokes of the two-stage driving mechanism run in sequence to minimize the probability of error.

[0037] In another embodiment provided by the present invention, further, a horizontal portion 4 is constructed on the workbench 1, and sliders 2 and movable blocks 3 are arranged on both sides of the horizontal portion 4. A slide groove 5 is constructed on the workbench 1, and the two sliders 2 are slidably connected in the slide groove 5. Specifically, the two sliders 2 protrude from the top surface of the workbench 1, and the top surface of the horizontal portion 4 and the top surfaces of the two sliders 2 are maintained on the same plane; the slide groove 5 is arranged along the length direction of the horizontal portion 4, so that the two sliders 2 can approach or move away from each other along the length direction of the horizontal portion 4. The advantage of such an arrangement is that when the two sliders 2 and the horizontal portion 4 are fitted, the top surfaces of the three are smoothly connected, so that the textile can be directly placed on the horizontal portion 4, and at the same time, the opposite ends of the textile are respectively on the two sliders 2, and then the two movable blocks 3 are driven by the two-stage driving mechanism to clamp and stretch the opposite ends of the textile to complete the stretching operation.

[0038] Furthermore, the two-stage driving mechanism includes a lifting plate 6, the lifting plate 6 is provided with an inclined groove 7, and the movable block 3 is slidably connected in the inclined groove 7. Support frames 8 are fixed on both sides of the workbench 1, a top plate 9 is fixed on the support frame 8, and a driving member 10 for driving the lifting plate 6 to rise and fall is fixed on the top plate 9. Specifically, the widths of the workbench 1, the slider 2, the movable block 3 and the flat portion are substantially the same, support frames 8 are fixed on both sides of the workbench 1, and the top plate 9 is fixed on the top of the two support frames 8. The driving member 10 can be a cylinder or a hydraulic cylinder in the prior art, which is vertically fixed on the top plate 9. The connection between the output end of the driving member 10 and the lifting plate 6 can be a fixed connection, so as to drive the lifting plate 6 to rise and fall on the workbench 1 when the driving member 10 is running; the lifting plate 6 is located on one side of the workbench 1, and the lifting plate 6 is symmetrically constructed with two inclined grooves 7 on one side close to the workbench 1, and the two movable blocks 3 are respectively slidably connected in the two inclined grooves 7, and the bottom ends of the two inclined grooves 7 are closer to the center of the workbench 1; the movable block 3 is set as a counterweight block, which has a certain weight, so that the movable block 3 can move to the bottom end of the inclined groove 7 (that is, the end of the inclined groove 7 close to the center of the workbench 1) under the action of gravity; in this way, when the lifting plate 6 is in a position close to the top plate 9, the two movable blocks 3 move to the bottom end of the corresponding inclined groove 7 under the action of gravity, and the textile can be placed on the horizontal portion 4 and the slider 2 , then the driving member 10 controls the lifting plate 6 to descend until the movable block 3 fits with the slider 2, and the movable block 3 presses the textile end against the slider 2 under the action of gravity, which is the first stroke of the two-stage driving mechanism; then the driving member 10 controls the lifting plate 6 to continue to descend, and the movable block 3 and the slider 2 can be forced to move away from the horizontal part 4 while clamping the textile end through the inner wall of the inclined groove 7 (the movable block 3 presses the textile end under the action of gravity and drives the slider 2 away from the horizontal part 4 along the slide groove 5 through friction. Obviously, the greater the mass of the movable block 3, the greater the pressure on the textile, the greater the friction between the textile and the slider 2, and the more stable the operation of the device), thereby stretching the textile, which is the second stroke of the two-stage driving mechanism; conversely, when the lifting plate 6 rises, the inner wall of the inclined groove 7 can force the movable block 3 and the slider 2 to approach the plane portion along the slide groove 5 until the slider 2 moves to a position fitting the plane portion, and the lifting plate 6 continues to rise to drive the movable block 3 to separate from the slider 2, thereby driving the slider 2 and other structures to reset to shrink the textile.

[0039] In order to improve the clamping force of the movable block 3 and the slider 2 on the textile end, preferably, the movable block 3 and the slider 2 are both magnet blocks. Specifically, the opposite side of the movable block 3 and the slider 2 is a magnetic pole of opposite polarity, so that the movable block 3 can attract the slider 2 after the lifting plate 6 descends, so as to improve the clamping force of the movable block 3 and the slider 2 on the textile end through magnetic attraction; conversely, when the lifting plate 6 rises, the resistance force of the inner wall of the inclined groove 7 on the movable block 3 can force the movable block 3 to separate from the slider 2.

[0040] Furthermore, a pin 11 is constructed on one side of the movable block 3, and a slot 12 adapted to the pin 11 is constructed on one side of the slider 2. Specifically, the pin 11 is located on the side of the movable block 3 away from the lifting plate 6, the slot 12 and the pin 11 are on the same side and the positions of the two correspond to each other, and the slot 12 is composed of a protruding structure on the side of the slider 2. The advantage of such a setting is that when the movable block 3 is close to the slider 2, the pin 11 is inserted into the corresponding slot 12 to limit the horizontal position of the movable block 3 and the slider 2, so that the movable block 3 and the slider 2 can slide stably along the slide groove 5 together, and try to avoid the movable block 3 and the slider 2 from sliding relative to each other when the movable block 3 and the slider 2 stretch the textile.

[0041] In the above embodiment, the movable block 3 and the slider 2 can attract each other through magnetic force, wherein the movable block 3 is at the bottom of the inclined slot 7 under the action of gravity, and the position of the slider 2 is easily offset in the slot 5 and away from the plane part, which will cause the movable block 3 and the slider 2 to be easily misaligned, and easily cause the position deviation of the textile end. For this reason, the top of the slot 12 can be constructed as an open opening, so that the pin 11 can be inserted into the open opening of the slot 12 when the movable block 3 descends, thereby correcting the position of the slider 2. As an alternative to the top of the slot 12 being constructed as an open opening, preferably, a wedge block 13 is slidably connected to the workbench 1, and a first elastic member 14 for forcing the wedge block 13 to be inserted into the slot 12 is also provided on the workbench 1. Specifically, a protrusion is constructed on the side of the workbench 1 away from the lifting plate 6, and a wedge block 13 is inserted into the protrusion, so that the wedge block 13 has a certain vertical sliding stroke on the protrusion; the first elastic member 14 can select a spring structure in the prior art, one end of which is fixed to the bottom end of the wedge block 13, and the other end is fixed to the outer wall of the workbench 1, so that the wedge block 13 is forced to slide to the top of its stroke through the first elastic member 14 and inserted into the corresponding slot 12, so that the slider 2 can be restricted to the position of the flat part by the wedge block 13; in this embodiment, when the slider 2 is in contact with the horizontal part 4, the pin 11, the slot 12 and the wedge block 13 are on the same vertical plane; when the movable block 3 descends with the lifting plate 6, it will press the textile end on the slider 2 under the action of gravity and magnetic force. During the process, the bottom end of the pin 11 is inserted into the corresponding slot 12 and contacts the wedge block 13, so as to force the wedge block 13 to overcome the elastic force of the first elastic member 14 and descend and move out of the slot 12 (such as Figure 3 Then the lifting plate 6 continues to descend to force the movable block 3 and the slider 2 to move away from the plane portion synchronously. After the pin 11 moves away from the wedge block 13, the pin 11 is reset under the action of the first elastic member 14 (as shown in FIG. Figure 4As shown); when the lifting plate 6 moves upward, the movable block 3 and the slider 2 approach the plane portion synchronously, until the slider 2 is about to approach the plane portion, the outer wall of the slot 12 (that is, the outer wall of the convex structure on the side of the slider 2 constituting the slot 12) can resist the wedge surface of the wedge block 13 to force the wedge block 13 to fall again, until the slider 2 is close to the plane portion, the wedge block 13 moves relatively to the bottom of the pin 11, and then the lifting plate 6 rises and drives the movable block 3 to rise, the wedge block 13 can be inserted into the corresponding slot 12 under the action of the first elastic member 14 to limit the position of the slider 2 again. The advantage of such a setting is that by setting the wedge block 13, the slider 2 can be restricted to the position close to the plane portion, until the movable block 3 and the slider 2 are in contact, the wedge block 13 passively releases the restriction on the slider 2, so that the slider 2 and the movable block 3 can be synchronously moved away from or close to the plane portion, and the position of the slider 2 is prevented from being offset after the movable block 3 and the slider 2 are separated.

[0042] It should be noted that the magnetic attraction between the movable block 3 and the slider 2 and the gravity of the movable block 3 are greater than the elastic force of the first elastic member 14, so that the movable block 3 can force the wedge block 13 to descend through the pin 11 while pressing the end of the textile, and the bottom end of the pin 11 is slightly exposed from the bottom end of the slot 12, so as to avoid the situation where the pin 11 cannot force the wedge block 13 to move out of the slot 12 due to the presence of textile between the movable block 3 and the slider 2.

[0043] In another embodiment provided by the present invention, further, the movable block 3 is constructed with an extension portion 15, a connecting rod 16 is hinged on the extension portion 15, a roller 17 is rotatably connected to the end of the connecting rod 16, and a torsion spring is provided between the extension portion 15 and the connecting rod 16. A stopper 19 is constructed on the extension portion 15, and an engaging groove 18 adapted to the connecting rod 16 is constructed at the bottom of the movable block 3. Specifically, the side of the movable block 3 close to the center of the workbench 1 is constructed with the extension portion 15, and the extension portion 15 is slightly higher than the bottom surface of the movable block 3; Figure 6 As shown, the movable block 3 fits the slider 2 to press the textile, and the connecting rod 16 is constructed in a Z shape, one end of which is kept in the same plane as the extension portion 15 (try to avoid the part of the connecting rod 16 located outside the fitting groove 18 from fitting the textile on the horizontal portion 4), and the other end is located in the fitting groove 18 and the bottom surface is smoothly connected to the bottom surface of the movable block 3; the stopper 19 is provided to limit the rotation angle of the connecting rod 16, so that the rotation range of the connecting rod 16 is less than 90 degrees, that is, the connecting rod 16 can be rotated from the position of contacting the fitting groove 18 to the position of contacting the stopper 19; the torsion spring is used to force the connecting rod 16 to rotate to the position of contacting the stopper 19, at which time the angle between the connecting rod 16 and the extension portion 15 is an acute angle (such as Figure 5As shown); the roller 17 is rotatably connected to the end of the connecting rod 16 away from the extension part 15, and the roller 17 is arranged along the width direction of the plane part. In this way, when the movable block 3 descends with the lifting plate 6 but is not close to the slider 2, the connecting rod 16 hits the stopper 19 under the action of the torsion spring. At this time, the descent of the movable block 3 can drive the roller 17 to hit the plane part. As the lifting plate 6 descends, the reaction force of the plane part on the roller 17 can force the connecting rod 16 to overcome the elastic force of the torsion spring and rotate into the fitting groove 18. Accordingly, the roller 17 will be attached to the plane part and roll to one side of the slider 2 under the action of the torsion spring until the movable block 3 and the slider 2 are close. Then, the roller 17 rotates to the side of the movable block 3 away from the plane part. At this time, the end of the connecting rod 16 away from the extension part 15 is embedded in the fitting groove 18 to cooperate with the movable block 3 to press the textile on the slider 2 (as shown in FIG. 2 ). Figure 6 As shown); in this process, the movable block 3 does not shift in position under the action of its own gravity, that is, the reaction force of the plane part on the connecting rod 16 cannot force the movable block 3 to move up along the inclined groove 7. The advantage is that by setting the connecting rod 16 and the roller 17, the textile on the plane part and the slider 2 can be rolled during the descent of the lifting plate 6, so as to apply a pre-tension to the textile while smoothing the textile, that is, the roller 17 forces the opposite ends of the textile to move away from each other so as to stretch on the plane part and the slider 2, and try to avoid wrinkles on the textile during the elasticity test. At the same time, the setting of the connecting rod 16 and the roller 17 will not hinder the operation of the movable block 3 and the slider 2, so that the device can operate adaptively and provide the textile with a pre-tension required for an elasticity test.

[0044] In another embodiment provided by the present invention, as an alternative solution for the fixed connection between the output end of the driving member 10 and the lifting plate 6, further, a lifting slot 20 is vertically constructed on the support frame 8, the lifting plate 6 is slidably connected in the lifting slot 20, a movable slot 21 is constructed on the lifting plate 6, and a connecting portion 22 is fixed to the output end of the driving member 10 and the connecting portion 22 is inserted in the movable slot 21. Specifically, both ends of the supporting frame 8 are constructed with lifting slots 20, both ends of the lifting plate 6 are slidably connected in two lifting slots 20, and the movable slot 21 is vertically constructed on the lifting plate 6; in this embodiment, the driving member 10 can be selected to be a cylinder or hydraulic cylinder structure, which is vertically fixed on the top plate 9, and the connecting portion 22 is fixed to the output end of the driving member 10 and movably arranged in the movable slot 21. With such arrangement, when the driving member 10 drives the connecting portion 22 to descend, the lifting plate 6 moves down along the lifting groove 20 under the action of gravity, and at the same time, the connecting portion 22 moves up relatively along the movable groove 21 until the connecting portion 22 contacts the top wall of the movable groove 21, and the position of the lifting plate 6 no longer drops, and then the driving member 10 drives the connecting portion 22 to continue to descend, and the lifting plate 6 drops accordingly under the action of gravity, and the connecting portion 22 always contacts the top wall of the movable groove 21; until the movable block 3 contacts the slider 2, the lifting plate 6 and the movable block 3 and other structures will be supported on the slider 2, and the driving member 10 continues to drive the connecting portion 22 to descend to form Figure 8 In the state shown, the movable block 3 and the slider 2 are attracted by magnetic force and clamp the end of the textile, and the weight of the lifting plate 6 and the slider 2 is completely supported on the slider 2, so that the weight of the lifting plate 6 and the slider 2 can passively force the two sliders 2 to move away from each other, and then use the gravity of the lifting plate 6 and the slider to stretch the textile (in the process of stretching the textile by gravity, the driving member 10 does not run, and the connecting part 22 only moves relatively in the movable groove 21), so that the elasticity of the textile can be tested using the specified tension; after the movable block 3 and the slider 2 are fitted, the pin 11 is inserted into the card slot 12, at this time, the horizontal component force from the lifting plate 6 on the movable block 3 is the tension on the end of the textile, and the weight of the lifting plate 6 is constant, and its horizontal pressure on the movable block 3 is also constant, so that the textile can be tested for elasticity using the constant force method; preferably, a counterweight structure can be assembled on the lifting plate 6 to perform a constant force method test on the textile under different tension conditions.

[0045] Figure 8 In the embodiment, the gravity of the lifting plate 6 and other structures acts on the movable block 3, so that the lifting plate 6 continues to descend under the action of gravity. At this time, the driving member 10 continues to operate to drive the connecting portion 22 to continue to move downward, so that the connecting portion 22 contacts the bottom wall of the movable groove 21, thereby driving the lifting plate 6 to continue to descend along the lifting groove 20 to form Fig. 9In the state shown, the lifting plate 6 is lowered to the bottom of its stroke, and the two sliders 2 are also moved to the extreme position away from the plane part, so that the textile can be stretched to a specified length to achieve an elastic test of the fixed elongation method. Whether it is the fixed force method or the fixed elongation method, the driving member 10 drives the connecting part 22 to move upward to drive the movable block 3 and the slider 2 and other structures to reset, so that the textile shrinks, and then the size and other data of the textile after shrinkage are measured to complete an elastic test. The advantage of such a setting is that by setting the connecting part 22 and the movable groove 21, the textile can be selectively subjected to a fixed force method elastic test or a fixed elongation method elastic test based on the operation of the driving member 10, so as to improve the scope of application of the device.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
