Description

Technical Field

[0001] The utility model relates to the technical field of paper product powder loss rate detection, in particular to a paper product powder loss rate detection device. Background Art

[0002] Powder loss testing typically measures the rate of powder shedding caused by friction and other factors during use of paper or similar materials. This test is crucial for assessing product quality and safety, particularly in the production and quality control of household paper products such as toilet paper and paper towels. The typical method for testing powder loss is to subject a sample to oscillation within a chamber for a specified time (usually two minutes). After the oscillation period, the sample is removed and weighed. The difference between the treated sample mass and the original mass is calculated, and this difference divided by the original mass yields the powder loss rate.

[0003] Currently, existing technologies all use a swinging method to test the dusting rate of paper products. Furthermore, the existing Chinese patent CN1 10333161B employs automatic clamping and positioning to reduce manual errors during the dusting rate test. However, this solution requires additional control procedures to control the cantilever and clamping head to clamp the paper product onto the weight sensor for weighing. This requires multiple steps and can easily reduce the efficiency of dusting rate testing.

[0004] In addition, the detection devices in the prior art only provide one detection method, which makes it impossible to verify the detection results, and thus cannot ensure the accuracy of the detection results. Utility Model Content

[0032] 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.

[0033] In order to address the shortcomings of existing technologies, such as Figure 1 and 2 As shown, the utility model provides a device for detecting the powder loss rate of paper products, comprising a chassis 2, wherein the front and rear sides of the chassis 2 are movably connected to a box door 3 by hinges, and movable wheels 4 are installed at the four corners of the bottom of the chassis 2. A control terminal 1 is provided on the top of the chassis 2, and an indicator light 5 controlled by the control terminal 1 is provided on one side of the top of the chassis 2. When the indicator light 5 is on, it indicates that the detection is in progress, and conversely, when the indicator light 5 is off, it indicates that the detection is completed. This setting can help staff judge the progress status of the detection;

[0034] like Figure 3 As shown, the chassis 2 is internally provided with a detection component 6 for detecting the powder loss rate of paper products; the detection component 6 includes a clamping claw 61 for clamping paper products, specifically, as shown in FIG. Figure 4 、 5 As shown in Figure 7, a swing drive mechanism 62 for driving the paper product to swing left and right is provided on the top of the clamping jaw 61. The swing drive mechanism 62 includes a connecting rod 621 fixed to the top of the clamping jaw 61. The top of the connecting rod 621 passes through the closed box 655 and is fixed with a slider 622. The top of the slider 622 is engaged with a swing rod 623. The rear side of the swing rod 623 is provided with a turntable 624 for driving the slider 622 to move left and right. The rear side of the turntable 624 is provided with a motor 625 for driving the turntable 624 to rotate.

[0035] Moreover, a mounting plate 626 is provided between the turntable 624 and the motor 1 625. The motor 1 625 is mounted on the rear side of the mounting plate 626 through a bracket. Both ends of the mounting plate 626 are fixed to the inner wall of the chassis 2. A motion track 627 is fixed to the bottom front side of the mounting plate 626 to limit the moving direction of the slider 622. The motor 1 625 in the present invention drives the turntable 624 to rotate. The rotating turntable 624 drives the bottom end of the rocker arm 623 to swing left and right. Then the swinging rocker arm 623 drives the slider 622 to drive the connecting rod 621 and the clamping claw 61 at the bottom end of the connecting rod 621 to swing left and right. In this process, the connecting rod 621 passes through the motion track 627 and moves left and right inside the motion track 627 to ensure that the clamping claw 61 can drive the clamped paper product to move left and right to realize the swing of the paper product, so as to shake off the powder on the paper product.

[0036] like Figure 4-6As shown, two weight sensors 63 distributed up and down are provided at the bottom of the clamping jaw 61. The weight sensors 63 are installed inside the cabinet 2 through a rotating mechanism 65. The rotating mechanism 65 includes a rotatable cylinder 651. Discs 652 are provided on both sides of the cylinder 651. The discs 652 are fixed to the inner wall of the chassis 2. A hollow shaft 653 is movably connected between the two discs 652 through a bearing. A second motor 654 is provided at one end of the hollow shaft 653 to drive the cylinder 651 to drive the two weight sensors 63 to rotate. The outer end of the second motor 654 is covered with a motor protective shell 7. The motor protective shell 7 is fixed to the outer wall of the chassis 2. The motor protective shell 7 can protect the second motor 654.

[0037] The two weight sensors 63 in the present invention are respectively embedded in the top and bottom of the cylinder 651, and a closed box 655 is provided on the top of the cylinder 651. The clamping claws 61 clamp the paper product and are located inside the closed box 655. The bottom of the closed box 655 is tangent to the outer wall of the cylinder 651. The front side of the closed box 655 is movably connected to a transparent door via a damping hinge. After closing the transparent door, the paper product can be enclosed between the closed box 655 and the cylinder 651. At this time, the powder shaken off from the shaking paper product will directly fall on the weight sensor 63 installed on the top of the cylinder 651. The weight of the shaken powder is weighed by the weight sensor 63. The original mass of the paper product is recorded as m0, and the weight of the powder shaken off is recorded as m1. The powder loss rate is calculated as follows: T1 = ((m0-m1) / m0) × 100%;

[0038] Then, motor 2 654 is started, driving hollow shaft 653 to rotate cylinder 651 180°, flipping weight sensor 63 at the bottom to the top. Then, jaws 61 are controlled to open, releasing the clamped paper product, allowing it to fall onto the top of the other weight sensor 63. The weight of the shaken paper product is measured and recorded as m2. The formula for calculating the powder loss rate is: T2 = (m2 / m0) × 100%. The present invention provides two different calculation methods for calculating the powder loss rate of paper products to improve the accuracy of the test results. By comparing the difference between T1 and T2, it can help personnel determine the accuracy of the measured powder loss rate.

[0039] In addition, if Figure 1-3As shown, the gripper 61, motor 1 625, and motor 2 654 in the present invention are all controlled by a control terminal 1. Two weight sensors 63 are connected to the control terminal 1 via wires 64. The weights m1 and m2 measured by the weight sensors 63 are uploaded to the control terminal 1 for display. The control terminal 1 automatically calculates T1 and T2, as well as the difference between T1 and T2, according to a formula to ensure the accuracy of the test results. Furthermore, the control terminal 1 can be used to control the test process to avoid errors caused by manual operation, thereby further improving the accuracy of the powder loss rate test results.
