Description

Technical Field

[0001] This utility model belongs to the field of textile testing technology, and in particular relates to a clamping mechanism for testing the tear resistance of textiles. Background Technology

[0002] In the process of textile production and processing, tear resistance is an important indicator for testing the quality of textiles. When conducting tear resistance tests, it is necessary to use a clamping mechanism to hold the textiles to ensure the smooth progress of the test.

[0003] Chinese utility model patent CN215414722U discloses a clamping, stretching, and rotating device for textile testing. The device includes a support frame and two clamping mechanisms arranged opposite each other on the support frame for clamping fabric. Each clamping mechanism includes a clamping base, a clamping block, and a positioning element. The clamping base has a placement groove for placing the fabric. The clamping block is movably disposed in the placement groove to clamp the fabric. The positioning element is disposed between the clamping base and the clamping block to fix the clamping block. This device can test both the tensile properties and wrinkle resistance of the fabric, improving testing efficiency, saving costs, and possessing high practicality. However, this device only clamps the textile using the clamping base and clamping block, resulting in relatively weak clamping force. During tear testing, excessive tension can easily cause the textile to detach from the clamping mechanism, affecting the tear resistance test results.

[0004] Therefore, there is an urgent need to improve the existing clamping, stretching, and rotating devices for textile testing, and to provide a clamping mechanism for testing the tear resistance of textiles with stronger clamping force. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a reasonably designed, simple structure, dual clamping function, and stronger clamping force for testing the tear resistance of textiles, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A clamping mechanism for testing the tear resistance of textiles includes a fixed plate and a chassis. The fixed plate is fixedly mounted on the upper surface of the chassis. A fixed clamping plate is vertically fixed above one end of the fixed plate, and a movable clamping plate is slidably mounted above the other end of the fixed plate. A first electric push rod is fixedly mounted at the middle of the bottom end of the fixed clamping plate, and the telescopic end of the first electric push rod is fixedly connected to the movable clamping plate. A horizontal plate is fixed to the middle of the outer wall of the movable clamping plate near the fixed clamping plate. A through groove structure is formed at the height position corresponding to the horizontal plate at the bottom end of the fixed clamping plate. First clamping parts that can interlock are fixed on the top sides of both the movable clamping plate and the fixed clamping plate. Two support rods are symmetrically fixed to the outer wall of the fixed clamping plate away from the movable clamping plate. Clamping components are installed on the support rods corresponding to the through groove structure. A pushing component for controlling the operation of the clamping components is provided between the two support rods.

[0007] Preferably, the bottom surface of the movable clamping plate slides in contact with the upper surface of the fixed plate, and the heights of the fixed clamping plate and the movable clamping plate are equal.

[0008] Preferably, the clamping assembly includes a movable frame, a lower clamping plate, and an upper clamping plate. The movable frame includes two vertical sections on the left and right, and a horizontal section located at the top of the vertical sections. The two vertical sections on the left and right are slidably connected to two support rods respectively. The lower clamping plate is fixedly installed at the bottom of the movable frame, and the upper clamping plate is provided directly above the lower clamping plate. The left and right ends of the upper clamping plate are slidably sleeved on the outside of the two vertical sections of the movable frame respectively.

[0009] Preferably, the lower clamping plate and the upper clamping plate are arranged symmetrically about the through groove structure inside the bottom end of the fixed clamping plate, and the lower clamping plate and the upper clamping plate are linked by a pushing component and their sliding directions are opposite to each other.

[0010] Preferably, both the lower and upper clamping plates are fixedly installed with second clamping parts that can interlock with each other on the side of the cross plate that is close to each other, and brackets are fixedly installed at the middle of the upper end face of the horizontal section of the movable frame and the upper clamping plate.

[0011] Preferably, the pushing assembly includes a fixed shaft, a rotating rod, and connecting rods. The fixed shaft is fixedly mounted on the outer wall of the fixed clamping plate on the side away from the movable clamping plate. The rotating rod is sleeved on the outer bearing of the fixed shaft. Both ends of the rotating rod are hinged to connecting rods. The ends of the two connecting rods away from the rotating rod are respectively hinged to two brackets provided in the clamping assembly.

[0012] Preferably, a second electric push rod is also hinged to the outer wall of the fixed clamp on the side opposite to the movable clamp, and the telescopic end of the second electric push rod is hinged to the rotating rod.

[0013] Preferably, the second electric actuator and the first electric actuator are electrically connected to an existing external controller via a connecting wire.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the movable clamping plate can be horizontally moved towards the fixed clamping plate by the first electric push rod. The first clamping parts on the top of both the movable and fixed clamping plates can interlock to facilitate strong clamping of textiles. When the movable clamping plate moves, it can also push part of the textiles into the clamping assembly through the horizontal plate. The second clamping parts fixed on the side of the lower and upper clamping plates that are close to the horizontal plate can interlock to achieve secondary clamping of textiles. Compared with the prior art, this device can achieve double clamping of textiles, and the clamping force is stronger and the effect is better.

[0015] This invention controls the extension and retraction of the second electric push rod, which in turn drives the rotating rod to rotate around the fixed axis. This allows the two connecting rods to push the upper clamping plate and the movable frame to rise and fall vertically in opposite directions, thus enabling convenient adjustment of the distance between the upper and lower clamping plates and facilitating the clamping of textiles.

[0018] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings: like Figure 1-5 As shown in the figure, the clamping mechanism for testing the tear resistance of textiles of this utility model includes a fixed plate 1 and a base plate 2. The fixed plate 1 is fixedly installed on the upper surface of the base plate 2. A fixed clamping plate 3 is vertically fixed above one end of the fixed plate 1, and a movable clamping plate 4 is slidably provided above the other end of the fixed plate 1. The top sides of the movable clamping plate 4 and the fixed clamping plate 3, which are close to each other, are fixed with first clamping parts 5 that can interlock with each other. A first electric push rod 6 is fixedly installed at the middle of the bottom end of the fixed clamping plate 3. The telescopic end of the first electric push rod 6 is fixedly connected to the movable clamping plate 4. Two support rods 7 are symmetrically fixed on the outer wall of the fixed clamping plate 3 away from the movable clamping plate 4. A clamping assembly 8 is installed on the support rods 7. A pushing assembly 9 for controlling the operation of the clamping assembly 8 is provided between the two support rods 7. A horizontal plate 10 is fixed at the middle of the outer wall of the movable clamping plate 4 near the fixed clamping plate 3.

[0019] As a preferred embodiment, based on the above structure, the bottom end face of the movable clamping plate 4 is further fitted and slidably attached to the upper end face of the fixed plate 1, the fixed clamping plate 3 and the movable clamping plate 4 are at the same height, and a through groove structure is provided at the bottom end of the fixed clamping plate 3 at the height position corresponding to the horizontal plate 10.

[0020] In this embodiment, the movable clamping plate 4 slides and cooperates with the fixed clamping plate 3 to facilitate the initial clamping of textiles.

[0021] As a preferred embodiment, based on the above structure, the clamping assembly 8 further includes a movable frame 81, a lower clamping plate 82, and an upper clamping plate 83. The movable frame 81 includes two vertical sections on the left and right and a horizontal section located at the top of the vertical sections. The two vertical sections on the left and right are slidably connected to two support rods 7 respectively. The lower clamping plate 82 is fixedly installed at the bottom of the movable frame 81. The upper clamping plate 83 is provided directly above the lower clamping plate 82. The left and right ends of the upper clamping plate 83 are slidably sleeved on the outside of the two vertical sections of the movable frame 81 respectively.

[0022] As a preferred embodiment, based on the above structure, the lower clamping plate 82 and the upper clamping plate 83 are arranged symmetrically about the through groove structure inside the bottom end of the fixed clamping plate 3. The lower clamping plate 82 and the upper clamping plate 83 are linked by the pushing component 9 and their sliding directions are opposite to each other.

[0023] In this embodiment, by pushing component 9 to control the upper clamping plate 83 and the lower clamping plate 82 to slide in opposite directions, it is convenient to achieve secondary clamping of textiles.

[0024] As a preferred embodiment, based on the above structure, both the lower clamping plate 82 and the upper clamping plate 83 are further provided with a second clamping part 11 that can interlock with each other on the side of the horizontal plate 10 that is close to each other, and a bracket 84 is fixedly provided on the horizontal section of the movable frame 81 and the middle position of the upper end face of the upper clamping plate 83.

[0025] In this embodiment, by using multiple interlocking second clamping parts 11, the clamping force on the textile can be enhanced, preventing the textile from detaching from the clamping mechanism during the test.

[0026] As a preferred embodiment, based on the above structure, the pushing component 9 further includes a fixed shaft 91, a rotating rod 92 and a connecting rod 93. The fixed shaft 91 is fixedly mounted on the outer wall of the fixed clamping plate 3 on the side away from the movable clamping plate 4. The rotating rod 92 is sleeved on the outer bearing of the fixed shaft 91. Both ends of the rotating rod 92 are hinged to the connecting rod 93. The ends of the two connecting rods 93 away from the rotating rod 92 are respectively hinged to the two brackets 84.

[0027] As a preferred embodiment, based on the above structure, a second electric push rod 94 is further hinged to the outer wall of the fixed clamping plate 3 on the side opposite to the movable clamping plate 4. The telescopic end of the second electric push rod 94 is hinged to the rotating rod 92. The second electric push rod 94 and the first electric push rod 6 are electrically connected to an existing external controller through a connecting line.

[0028] In this embodiment, the second electric push rod 94 can be used to drive the rotating rod 92 to rotate around the fixed shaft 91, so that the two connecting rods 93 can be used to push the upper clamping plate 83 and the lower clamping plate 82 to rise and fall in opposite directions, thereby making it easy to adjust the distance between them.

[0029] The working principle of this utility model is as follows: When in use, first place one end of the textile to be tested between the fixed clamping plate 3 and the movable clamping plate 4, and leave an appropriate length below the horizontal plate 10. Then, control the first electric push rod 6 to retract and drive the movable clamping plate 4 to move stably and approach the fixed clamping plate 3. The first clamping part 5 provided on the top of the two clamps interlocks with each other, which can clamp the textile in an interlocking manner with higher clamping force. When the movable clamping plate 4 moves, the reserved textile can be pushed into the clamping assembly 8 through the horizontal plate 10. At this time, the second electric push rod 94 can be activated to extend it, which can push the rotating rod 92 to rotate around the fixed shaft 91. Thus, the two connecting rods 93 can be used to push the two brackets 84 to drive the upper clamping plate 83 and the movable frame 81 to move vertically in opposite directions. This allows for convenient adjustment of the distance between the upper clamping plate 83 and the lower clamping plate 82. The second clamping part 11 fixed on the side of the lower clamping plate 82 and the upper clamping plate 83 that is close to each other can be used to engage with the textile for easy clamping again. In summary, this device has dual clamping functions, both of which use an interlocking clamping method, resulting in stronger and better clamping force for textiles. It should be noted that the chassis 2 in this device is installed on a rotating base in the prior art using the existing method. The device is powered by an external power source. The first electric push rod 6 and the second electric push rod 94 are electrically connected to an external existing controller through a connecting line. The specific control method is a mature technology. The above is not the key innovation of this case, so it will not be described in detail.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
