Description

Technical Field

[0001] The utility model relates to an auxiliary device for detecting the strength of paper in papermaking production, belonging to the technical field of mechanical measurement. Background Technique

[0002] The detection methods of paper strength include the detection of three strength properties: tensile, compressive and tear resistance. When detecting the tensile strength, the measurement methods mainly include the breaking length method, the suspension method and the peeling method.

[0003] In the prior art, a Chinese utility model patent with the publication number of CN206470125U discloses a horizontal computerized tensile tester. The multi-degree-of-freedom gripper of this patent is arranged on the body of the computerized tensile tester and is located between the moving chuck and the static chuck. The clamping seat is a U-shaped seat body, and the clamping seat is detachably connected to the test bench of the computerized tensile tester body. There are four-way grooves at the top of the clamping seat, and the bottom of the support frame is arranged in the four-way grooves and is slidably matched with the four-way grooves. The top of the support frame is hinged to the bottom plate. One end of the moving clamp frame is the operating end, and the other end of the moving clamp frame is the clamping end. The operating end of the moving clamp frame is hinged to the top surface of the bottom plate through a torsion spring, and the operating rod is arranged on the moving clamp frame.

[0004] The utility model is used in the detection process of paper products.

[0005] Based on the existing horizontal computerized tensile tester, the above technology is provided with a detachable multi-degree-of-freedom gripper. By clamping the middle part of the paper with the gripper, when the paper is clamped between the two chucks, the fingers do not need to reach inside the chucks, which can avoid clamping the fingers. However, since most papers are relatively soft, after the middle part of the paper is clamped, both ends will naturally droop at a certain angle, making it difficult for the paper to penetrate into the inside of the chucks, and still requires fingers to assist in lifting the ends of the paper, and the potential safety hazard cannot be completely eliminated. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an auxiliary device for detecting the strength of paper in papermaking production. Based on the existing horizontal computerized tensile tester, it is improved to avoid the fingers being clamped by the static chuck or the moving chuck when moving the paper, avoid the operator from being injured, and reduce the transformation cost.

[0007] The utility model discloses an auxiliary device for detecting the strength of paper used in papermaking production, comprising a fixed plate, a U-shaped clamp, a square guide rod, a rotating plate, a fixed shaft, a sliding plate and symmetrically arranged parallel brackets. The square guide rod penetrates the U-shaped clamp and mounts the U-shaped clamp on the rotating plate. The rotating plate is sleeved on the outer periphery of the fixed shaft and is rotatably connected to the parallel brackets through the fixed shaft. The sliding plate can move on the fixed plate toward or away from a static clamp. Two parallel brackets are mounted on both ends of the sliding plate and move on the fixed plate with the sliding plate. The height of the U-shaped clamp opening when in a horizontal state matches the height of the static clamp and the dynamic clamp.

[0008] The fixing plate is placed below one side of the static clamp and the dynamic clamp, with the opening of the U-shaped clamp facing upwards, the paper to be tested is installed in the U-shaped clamp, the U-shaped clamp is rotated to make the opening of the U-shaped clamp face the static clamp and the dynamic clamp, and the sliding plate is pushed to move in the direction close to the static clamp and the dynamic clamp until the paper enters the static clamp and the dynamic clamp. By setting the U-shaped clamp, the paper is clamped and the function of the hand is realized, thereby avoiding the hand from being clamped. By setting the square guide rod, the rotating plate and the fixed shaft, the rotation of the U-shaped clamp is realized, and the flexibility of the U-shaped clamp is improved; by setting the parallel bracket and the sliding plate, the forward and backward movement of the U-shaped clamp is realized; the height of the U-shaped clamp opening when in a horizontal state is adapted to the height of the static clamp and the dynamic clamp, so that the paper is easily inserted into the static clamp and the dynamic clamp.

[0009] The U-shaped clip is provided with a square sliding hole corresponding to the square guide rod, and the square guide rod penetrates the square hole on the U-shaped clip to mount the U-shaped clip on the rotating plate, and the U-shaped clip can slide on the square guide rod. The square sliding hole on the U-shaped clip can prevent the U-shaped clip from rotating on the square guide rod, and can also enable the U-shaped clip to slide on the square guide rod, thereby realizing the adjustment of the position of the U-shaped clip.

[0010] The number of the U-shaped clamps is two. The two U-shaped clamps clamp the paper at the positions near the two ends respectively, so that only a small part of the two ends of the paper extends outward from the U-shaped clamp 27, making it less likely that the two ends of the paper will bend downward due to gravity, that is, the two ends of the paper are horizontal, which facilitates the two ends of the paper to enter the static clamp and the dynamic clamp respectively. In addition, the positions of the two U-shaped clamps are adjustable, which can meet the requirements of papers of different sizes and improve the adaptability of the device.

[0011] The fixed plate is provided with a guide rod, and the sliding plate is provided with a guide slider corresponding to the guide rod. By providing the guide rod and the guide slider, the sliding plate can only move along a straight line, preventing the sliding plate from deviating left and right during the movement, and ensuring that the paper accurately enters the static clamp and the dynamic clamp.

[0012] The U-shaped clamp is provided with a paper fastening assembly, which includes a clamping plate that can move up and down, a T-shaped rod and a spring. The clamping plate is placed in the U-shaped clamp, and a through hole is provided on the U-shaped clamp. The T-shaped rod passes through the through hole on the U-shaped clamp and is connected to the clamping plate. One end of the spring is fixedly connected to the top of the T-shaped rod, and the other end is fixedly connected to the top of the U-shaped clamp. When not working, the clamping plate abuts against the bottom of the U-shaped clamp. When it is necessary to clamp the paper, the T-shaped rod is pulled, the spring is stretched, the clamping plate is lifted, and the paper is placed in the gap between the clamping plate and the U-shaped clamp. The T-shaped rod is released, and the clamping plate and the U-shaped clamp clamp the paper, thereby increasing the reliability of paper clamping and preventing the paper from falling during rotation and movement.

[0013] An arc-shaped curved plate is arranged between the two parallel brackets. The arc-shaped curved plate is a quarter of a circle. The arc-shaped curved plate is arranged cocentrically with the fixed axis. Magnets are arranged at both ends of the arc-shaped curved plate, and iron bars are arranged on the rotating plate corresponding to the magnets. By arranging the arc-shaped curved plate, the rotation range of the U-shaped clamp is limited to 90 degrees, thereby preventing the U-shaped clamp from rotating too much. By arranging the magnet on the arc-shaped curved plate and the iron bar on the rotating plate, the rotating plate will not shake in the horizontal and vertical directions under the action of the magnet, thereby improving the stability of the U-shaped clamp.

[0015] (1) The utility model realizes paper clamping by providing a U-shaped clamp, realizes the function of the hand, and thus prevents the hand from being clamped; the square guide rod, the rotating plate and the fixed shaft are provided to realize the rotation of the U-shaped clamp, thereby improving the flexibility of the U-shaped clamp; the parallel bracket and the sliding plate are provided to realize the forward and backward movement of the U-shaped clamp; the height of the U-shaped clamp opening in a horizontal state is adapted to the height of the static clamp head and the dynamic clamp head, so that the paper is easily inserted into the static clamp head and the dynamic clamp head.

[0016] (2) A paper fastening assembly is provided on the U-shaped clamp, and the paper fastening assembly includes a clamping plate that can move up and down, a T-shaped rod, and a spring. The clamping plate is placed in the U-shaped clamp, and a through hole is provided on the U-shaped clamp. The T-shaped rod passes through the through hole on the U-shaped clamp and is connected to the clamping plate. One end of the spring is fixed to the top of the T-shaped rod, and the other end is fixed to the top of the U-shaped clamp.

The T-shaped rod is released, and the clamping plate and the U-shaped clamp clamp the paper, thereby increasing the reliability of paper clamping and preventing the paper from falling during rotation and movement.

[0017] (3) An arc-shaped bent plate is arranged between two parallel brackets. The arc-shaped bent plate is a quarter of a circle. The arc-shaped bent plate is arranged cocentrically with the fixed axis. Magnets are arranged at both ends of the arc-shaped bent plate, and iron bars are arranged on the rotating plate corresponding to the magnets.
