Description

Technical Field

[0001] This utility model specifically relates to a device for detecting the dust shedding rate of paper towels, belonging to the field of paper towel testing technology. Background Technology

[0002] Currently, the papermaking instrument testing industry generally follows standards such as Appendix B (Normative) of GB / T 20808-2022 "Determination of Dust Shedding Rate" or Appendix B (Normative Appendix) of GB / T 20810-2018 "Determination of Dust Shedding Rate" for toilet paper (including toilet paper base paper), and designs and manufactures dust shedding rate measuring instruments for related tests. The design principle is to simulate pinching a tissue with fingers and shaking it to cause dust to fall, and then calculate the dust shedding rate based on this. Existing testing instruments on the market generally suffer from problems such as complex overall structure, non-standard sample clamping, and lack of automatic weighing and calculation functions.

[0003] Although the prior art CN110333161A discloses "a dusting rate detection device for household paper", it mainly achieves the movement of the clamp through the cooperation between the connecting rod, the circular rotary wheel and the linear guide rail, which is complex in structure and inconvenient to operate; in addition, the fixed clamp is prone to overload movement, etc.

[0004] Therefore, a device with a simple structure, stable clamping operation, and effective protection of the clamping mechanism is needed. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, a device for detecting the dust shedding rate of tissue paper is proposed. In this invention, through a specific arrangement of a base plate, transmission mechanism, weighing mechanism, and clamping mechanism, not only is accurate measurement of the dust shedding rate of tissue paper achieved, but the device also boasts a simple structure and convenient operation; simultaneously, it effectively protects the clamping mechanism and extends its service life.

[0006] To achieve the above technical objectives, the following technical solution is proposed:

[0007] A device for detecting the powder shedding rate of paper towels includes a base plate, a transmission mechanism disposed above the base plate, and a weighing mechanism and a clamping mechanism disposed below the base plate.

[0008] Base plate: The base plate is provided with a connecting through groove;

[0009] Transmission mechanism: includes a connecting plate fitted in the connecting through groove, the upper end of the connecting plate extends upward toward the bottom plate and the lower end extends downward toward the bottom plate; a slider and a linear guide rail are provided on the front side of the upper part of the connecting plate, the slider and the linear guide rail are fitted together, and the connecting plate is connected to the linear guide rail through the slider; the linear guide rail is parallel to the connecting through groove.

[0010] A transmission disc is located on the rear side of the upper part of the connecting plate, and a driver is located on the rear side of the transmission disc. The output shaft of the driver is connected to the transmission disc, and a traction component is provided on the transmission disc to move the connecting plate. When the driver is running, the transmission disc connected to the output shaft of the driver rotates synchronously, and the traction component mounted on the transmission disc drives the connecting plate and the slider to reciprocate along the linear guide rail.

[0011] Clamping Mechanism: Connected to the lower part of the connecting plate. Specifically, the clamping mechanism includes a gripper and a paper clamp. The gripper is located below the connecting plate and includes a telescopic rod (preferably a miniature electric push rod), a damper, and a chuck. Both the telescopic rod and the damper are connected to the lower part of the connecting plate, with the damper located on one side of the telescopic rod. The chuck is located below the telescopic rod and is connected to the lower part of the telescopic rod. The paper clamp is located below the chuck and is movably connected to the chuck. The paper clamp includes a clamp seat and a clamp, with the clamp connected to the chuck via the clamp seat. More specifically, the chuck has a positioning through-slot I that mates with the clamp seat, and the clamp seat has a positioning pin for mates with the weighing mechanism.

[0012] Weighing mechanism: Located on one side of the clamping mechanism, the weighing mechanism includes a sensor bracket located below the base plate. The sensor bracket is equipped with a weighing fork and a weighing sensor, with the weighing sensor located below the weighing fork. The weighing fork is provided with a positioning through groove II that cooperates with the positioning pin. Preferably, the positioning through groove II is located near the edge of the weighing fork.

[0013] Furthermore, the base plate is provided with a track bracket for mounting the linear track.

[0014] Furthermore, the driver is fixed to the base plate by a driver bracket to ensure smooth operation and accurate and reliable stopping position.

[0015] The positional relationships involved in this technical solution, such as "above", "below", "upper", "inner", "upper end", "lower end", "between", "upper part", "front side", "one side", and "near", are defined according to the actual usage conditions and are conventional terms in this technical field, as well as conventional terms used by those skilled in the art in actual use.

[0016] In the description of this technical solution, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technical solution based on the specific circumstances.

[0017] The beneficial technical effects of adopting this technical solution are as follows:

[0018] This invention, through a specific arrangement of a base plate, transmission mechanism, weighing mechanism, and clamping mechanism, not only achieves accurate measurement of paper towel dust shedding rate, but also ensures that the device has a simple structure and is easy to operate; at the same time, it can effectively protect the clamping mechanism and improve its service life.

[0019] Through specific arrangements between the transmission disc, connecting plate, slider and linear guide rail, the linear reciprocating linear motion of the connecting plate is realized, thereby ensuring that the connecting plate can carry the clamping mechanism to perform stable linear reciprocating motion, while ensuring that the overall structure of the device is simple.

[0020] In the clamping mechanism, the damper and the telescopic rod are properly coordinated to effectively prevent the telescopic rod from moving under overload, thereby ensuring that the sample clamping fully meets the standards.

[0021] In the weighing mechanism, the coordinated arrangement of the sensor bracket, weighing fork, and weighing sensor ensures that the device has an automatic weighing calculation function, thereby improving the accuracy of the detection, etc. Attached Figure Description

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] Example 1

[0033] This embodiment provides: a device for detecting the dust shedding rate of paper towels, such as... Figure 1-2 As shown, it includes a base plate 1, a transmission mechanism 2 located above the base plate 1, a weighing mechanism 3 located below the base plate 1, and a clamping mechanism 4. The base plate 1 is provided with a connecting through groove 11, and the weighing mechanism 3 is located on one side of the clamping mechanism 4.

[0034] The transmission mechanism 2 includes a connecting plate 21 sleeved in the connecting through groove 11. The upper end of the connecting plate 21 extends upward toward the bottom plate 1, and the lower end extends downward toward the bottom plate 1. A slider 22 and a linear guide rail 23 are provided on the front side of the upper part of the connecting plate 21. The slider 22 and the linear guide rail 23 are configured to cooperate with each other, and the connecting plate 21 is connected to the linear guide rail 23 through the slider 22. The linear guide rail 23 is arranged parallel to the connecting through groove 11. In a specific implementation, the linear guide rail can be installed on the surface of the bottom plate 1 through the rail bracket 27.

[0035] like Figure 2 As shown, a transmission disk 24 is provided on the rear side of the upper part of the connecting plate 21, and a driver 25 (preferably a variable frequency motor) is provided on the rear side of the transmission disk 24. The output shaft of the driver 25 is connected to the transmission disk 24, and a traction member 29 is provided on the transmission disk 24 to drive the connecting plate 21 to move. As a preferred embodiment, the traction member 29 is movably connected to the connecting plate 21, and the traction member 29 is located near the edge of the transmission disk 24. The connecting plate 21 is provided with a longitudinally arranged sliding through groove 211. One end of the traction member 29 is fixedly connected to the transmission disk 24, and the other end is sleeved in the sliding through groove 211 through a pulley 9. The sliding through groove 211 and the pulley 9 are configured to cooperate with each other. The clamping mechanism 4 is connected to the lower part of the connecting plate 21. In a specific implementation, the driver 25 can be fixed to the surface of the base plate 1 through the driver bracket 28. When the driver 25 is running, the transmission disk 24 installed on the output shaft of the driver 25 rotates synchronously. The bearing installed on the transmission disk 24 drives the connecting plate 21 and the slider 22 to move back and forth along the linear guide rail 23. The back and forth movement of the connecting plate 21 realizes the back and forth movement of the clamping mechanism 4, so as to ensure the smooth operation of the paper towel dust rate detection work.

[0036] The cooperation between the slider 22 and the linear guide rail 23 ensures the stability of the movement of the connecting plate 21, thereby improving the smoothness of the movement of the clamping mechanism 4, and ultimately achieving accurate measurement of the paper towel dust rate, etc.

[0037] Example 2

[0038] Based on Embodiment 1, this embodiment further defines the clamping mechanism 4 to further illustrate the technical solution.

[0039] like Figure 2 As shown, the clamping mechanism 4 includes a clamp and a paper clamp 41. The clamp is located below the connecting plate 21 and includes a telescopic rod 42 (preferably a miniature electric push rod), a damper 43, and a chuck 413. Both the telescopic rod 42 and the damper 43 are connected to the lower part of the connecting plate 21, and the damper 43 is located on one side of the telescopic rod 42. The chuck 413 is located below the telescopic rod 42 and is connected to the lower part of the telescopic rod 42. The paper clamp 41 is located below the chuck 413 and is movably connected to the chuck 413. The paper clamp 41 includes a clamp seat 412 and a clamp 411. The clamp 411 is connected to the chuck 413 through the clamp seat 412, thereby ensuring that the sample clamping meets the standard. More specifically, the clamp 413 is provided with a positioning through groove I 415 that cooperates with the clamp seat 412, and the clamp seat 412 is provided with a positioning pin 414 for cooperating with the weighing mechanism 3.

[0040] More preferably, the telescopic rod 42 is a miniature electric push rod, which is small in size and has a large thrust, while the damper 43 can effectively prevent the electric push rod from overloading.

[0041] Example 3

[0042] Based on Examples 1-2, this example further defines the balancing mechanism 3 to further illustrate the technical solution.

[0043] like Figure 1 As shown, the weighing mechanism 3 includes a sensor bracket 31 located below the base plate 1. The sensor bracket 31 is equipped with a weighing fork 32 and a weighing sensor 33, with the weighing sensor 33 located below the weighing fork 32. The weighing fork 32 is provided with a positioning through groove II 34 that cooperates with the positioning pin 414. In specific implementation, the positioning through groove II 34 is located near the edge of the weighing fork 32, so that when the connecting plate 21 moves to the weighing mechanism 3, the telescopic rod 42 is released, and the positioning pin 414 on the paper clamp 41 falls into the positioning through groove II 34, which can automatically weigh the paper. This overcomes the shortcomings of manual handling of the sample, which causes the sample to shed powder and makes the test results inaccurate. Finally, the paper towel powder shedding rate is calculated according to the formula by weighing the paper towel twice before and after the test.

[0044] Example 4

[0045] Based on Examples 1-4, this example provides a tissue paper dust shedding rate detector, such as... Figure 3-4 As shown, the device includes a box-shaped housing fitted around the outside of the tissue paper dust rate detection device. A base plate 1 separates the box-shaped housing into an upper housing 5 and a lower housing 6. An upper cavity is formed inside the upper housing 5, primarily used to install the transmission mechanism 2, and, if necessary, a controller, etc. The upper housing 5 is equipped with a display screen and operation buttons. Furthermore, the back of the upper housing 5 has heat dissipation holes 7 for heat dissipation.

[0046] The lower housing 6 has a lower cavity, which is mainly used to install the clamping mechanism 4 and the weighing mechanism 3, as well as the operating space for detecting the paper towel dust rate. The upper housing 5 is equipped with a display screen and operating buttons. In addition, the front of the lower housing 6 has a door 8 for easy operation.

[0047] The operation process is as follows: Set the starting position to the right end. After the paper clamp 41 clamps the paper towel sample, place the whole sample on the chuck 413. First, clamp it. Then, driven by the driver 25, move the clamping mechanism to the left end. The clamping mechanism is released and the first weighing is performed. After weighing, clamp it again and make a back-and-forth motion according to the test standard requirements. After the motion is completed, weigh it again. After weighing, clamp it, return to the right end, release it, and the test is completed.
