Description

Technical Field

[0001] The invention relates to the technical field of tobacco detection, and in particular to a tobacco rod-shaped material inclination angle test device and a measuring method. Background Art

[0002] The cigarette making machine equipment currently used in the cigarette factory's packaging workshop involves the reception and transmission of filter rods. The friction between the filter rods and the cigarette making machine equipment components will directly affect the service life of the cigarette making machine equipment components and the efficiency of the machine operation. Therefore, the friction coefficient of the filter rod is an important parameter that the workshop pays attention to.

[0003] The tilt angle test is one of the test methods used in discrete element simulation to obtain the static friction coefficient and rolling friction coefficient between materials and between materials and contact surfaces. The Chinese utility model patent with the authorization announcement number CN206960328U discloses a measuring device for measuring the friction coefficient of filter rods. The measuring device is used for quick and easy measurement of the friction coefficient on site. It has a single purpose, low precision, relatively simple structural design, pure manual drive and adjustment, limited degree of automation, and the reading results also rely on manual judgment. It has operation sensitivity and large error in the results. The speed and stability of each manual loading vary from person to person, and the judgment of the end of the test also depends entirely on human reaction, which will affect the stability and accuracy of the test results. At the same time, tobacco rod-shaped materials involve multiple specifications. When the material specifications change, the operator needs to re-paste the material on the measuring plate, which takes a long period of time, and the density of the paste will also affect the test results. At the same time, the tilt angle test also has certain requirements for the horizontality of the measuring device, and the measuring device cannot adjust the level, resulting in limited accuracy of the test. Summary of the invention

[0071] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0073] Figure 1 FIG. 1 is a perspective view of a test device for the inclination angle of tobacco rod-shaped materials according to the present invention. In the following description, Figure 1 The attached figure in the figure is used as a reference for the direction. Figure 1 In the figure, the length direction of the extension platform 2 is defined as the left-right direction, and the movable platform 3 is located on the right side of the extension platform 2; the width direction of the extension platform 2 is defined as the front-back direction, and the distance scale 82 is set on the rear side of the extension platform 2; the height direction of the height scale 83 is defined as the up-down direction, and the falling mechanism is set above the movable platform 3.

[0074] like Figure 1 As shown, the present invention provides a tobacco rod-shaped material inclination angle test device, which includes a platform bracket 1, an extension platform 2, a movable platform 3, a driving mechanism, a falling mechanism, an angle scale 81, a distance scale 82, a height scale 83 and a distance sensor 84.

[0075] The bottom of the platform bracket 1 is provided with four adjustment legs 13, each of which is adjustable in height, and is used to keep the platform bracket 1 horizontal. The extension platform 2 is horizontally arranged on the platform bracket 1, and a distance scale 82 extending along the length direction of the extension platform 2 is arranged on the rear side of the extension platform 2, and a plurality of distance scales are arranged on the distance scale 82. The movable platform 3 is connected to the extension platform 2, and an end (i.e., the left end) of the movable platform 3 close to the extension platform 2 is provided with a rotating shaft 31 extending along the width direction of the extension platform 2, and the rotating shaft 31 is connected to the platform bracket 1 through the first support block 11. Specifically, the first support block 11 is provided with a plurality of long grooves extending in the left and right directions, and the long grooves are connected to the platform bracket 1 through fasteners. By adjusting the position of the fasteners in the long grooves, the left and right positions of the first support block 11 on the platform bracket 1 can be adjusted, thereby realizing fine adjustment of the left and right positions of the rotating shaft 31. Furthermore, a second support block 12 is also provided on the platform bracket 1, and the second support block 12 is used to support the end of the movable platform 3 away from the extension platform 2, so that the movable platform 3 is kept horizontal.

[0076] A plurality of mold boxes 5 are detachably mounted on the top of the extension platform 2 and the movable platform 3. The test personnel can lay the material in the mold box 5 to form the contact medium 7 required for the tilt angle test on the top of the extension platform 2 and the movable platform 3. Specifically, the material laid in the mold box 5 is the same as the material 6 to be tested, which is a tobacco rod-shaped material (such as a cigarette or a filter rod). When the material 6 to be tested has a variety of different specifications, the present invention can quickly replace the contact medium 7 by replacing the mold box 5 of the corresponding specifications. The replacement is more flexible and maximizes the continuity and stability of the test. Figure 1 , Figure 6 and Figure 7 As shown, multiple groups of mold box installation grooves 21 are opened on the top of the extension platform 2, and multiple groups of mold box installation grooves 34 are opened on the top of the movable platform 3. Each group of mold box installation grooves 21 / 34 includes two mold box installation grooves that are parallel to each other and extend along the width direction of the extension platform 2. The mold box 5 is inserted and matched with the mold box installation grooves. In this way, the mold box 5 can be stably installed, and the mold box 5 can be prevented from falling off from the top of the extension platform 2 or the movable platform 3 during the test, which affects the test progress or test results.

[0077] Preferably, a starting position mark 51 is provided on one of the mold boxes 5 in the movable platform 3 , and the material 6 to be tested can be subjected to relevant tests starting from the starting position mark 51 .

[0078] Furthermore, if Figure 1 , Figure 5 and Figure 6As shown, a fixed block 22 is provided at one end (i.e., the right end) of the extension platform 2 close to the movable platform 3, and a transition guide plate 52 is installed on the top of the fixed block 22. The transition guide plate 52 is located between the extension platform 2 and the movable platform 3, and is used to cover the gap between the extension platform 2 and the movable platform 3 to ensure that the material 6 to be measured can smoothly roll into the extension platform 2 along the movable platform 3.

[0079] A sensor platform 32 is also provided on the top of one end (i.e., the right end) of the movable platform 3 away from the extension platform 2, and a distance sensor 84 is mounted on the sensor platform 32. The distance sensor 84 is a prior art, which specifically includes a transmitter and a receiver, and can realize non-contact distance measurement through the principle of photoelectric effect.

[0080] like Figure 1-4 and Figure 7 As shown, the driving mechanism is used to drive the movable platform 3 to rotate around the rotating shaft 31. In a specific embodiment of the utility model, the driving mechanism includes a driving source 41, a linear displacement component 42 connected to the driving source 41, and a lifting portion 33 arranged at the bottom of the movable platform 3. The linear displacement component 42 includes a slide rail 423 extending along the length direction of the extension platform 2, a slider 421 slidingly arranged on the slide rail 423, and a lifting roller 422 rotatably arranged on the top of the slider 421. The slider 421 moves along the slide rail 423 under the drive of the driving source 41, and the lifting roller 422 abuts against the lifting portion 33. The thickness of the lifting portion 33 gradually decreases from the end close to the extension platform 2 (i.e., the left end) to the end away from the extension platform 2 (i.e., the right end). Furthermore, an arc surface is provided at the bottom of the lifting portion 33, and the arc surface abuts against the lifting roller 422. The driving source 41 is fixed on the driving mechanism bracket 14 of the platform bracket 1 . Its specific form is not limited and it can be a linear displacement driving device such as a screw motor, a hydraulic cylinder or a pneumatic cylinder, and its output end is connected to the slider 421 .

[0081] In the initial state, the slider 421 is located at the right end of the slide rail 423, and the right end of the movable platform 3 is placed on the second support block 12. At this time, the movable platform 3 and the extension platform 2 are in the same horizontal plane, and the distance between the right end of the lifting part 33 and the slider 421 is not less than the height of the lifting roller 422, so the lifting roller 422 has no lifting effect on the movable platform 3. In the process of the driving source 41 driving the slider 421 to move to the left, the distance between the lifting part 33 and the slider 421 gradually decreases, and the lifting roller 422 lifts the movable platform 3 upward. Under the lifting effect of the lifting roller 422, the movable platform 3 rotates counterclockwise around the rotating shaft 31, so its angle changes.

[0082] The angle scale 81 is arranged on the length direction side (i.e., the rear side) of the movable platform 3, and is provided with a plurality of angle scales. During the rotation of the movable platform 3, a side edge extending along the length direction thereof will coincide with a scale on the angle scale 81, so as to facilitate obtaining the angle value of the movable platform 3 at this time. The height scale 83 is arranged on the width direction side (i.e., the right side) of the movable platform 3 through a scale bracket 831, and is provided with a plurality of height scales.

[0083] like Figure 1-2 and Figure 8 As shown, the drop mechanism is arranged on the height scale 83, and is used to place the measured material 6 horizontally and make the measured material 6 fall freely. Specifically, the drop mechanism is located above the movable platform 3, and includes a support rod 92 arranged at a preset height of the height scale 83, the right end of the support rod 92 is fastened to the height scale 83 through a butterfly nut 91, and the left end is provided with a nut 96, a fixed baffle 93 and a movable part 97 from left to right, wherein the nut 96 and the fixed baffle 93 are both fixedly connected to the support rod 92, and the movable part 97 is slidably arranged on the support rod 92. The drop mechanism also includes a button 94, which penetrates the fixed baffle 93 and is connected to the movable part 97, and a reset spring 95 is also sleeved on the button 94, and the right end of the reset spring 95 abuts against the fixed baffle 93. A horizontal drop platform 971 is also provided at the bottom of the movable part 97, and the drop platform 971 penetrates the bottom of the fixed baffle 93 and extends to the left.

[0084] In the initial state, the reset spring 95 is in a natural state, and the movable part 97 is in contact with the fixed baffle 93; when performing the tilt angle rolling friction coefficient measurement test, the material 6 to be tested is placed on the drop platform 971, and then the button 94 is pressed to drive the movable part 97 to overcome the spring force and move in the direction away from the fixed baffle 93 (i.e., the right side), and the drop platform 971 is then retracted to the right side of the fixed baffle 93, and the material 6 to be tested falls freely from the drop platform 971. After the button 94 is stopped being pressed, the drop platform 971 is reset under the reset action of the reset spring 95, and the material 6 to be tested can be placed on the drop platform 971 again.

[0085] Furthermore, the test device of the present invention further includes a controller, which is respectively connected to the driving source 41 and the distance sensor 84. When the test of measuring the static friction coefficient of the inclined angle is performed, when the distance sensor 84 detects that the distance between it and the material 6 to be measured exceeds the threshold value, the distance sensor 84 sends a signal to the controller, and the controller controls the driving source 41 to stop working, so that the movable platform 3 stops rotating. This arrangement makes the test process of measuring the static friction coefficient of the inclined angle more automated, eliminates human interference to the maximum extent, and improves the accuracy of the test results.

[0086] The present invention also provides a method for measuring the inclination angle test device of the tobacco rod-shaped material, the method comprising the following steps:

[0087] like Figure 3 As shown, the movable platform 3 is adjusted to a horizontal position, and the material is evenly and continuously laid in the mold box 5 of the movable platform 3 and the extension platform 2 according to the specifications of the material 6 to be tested to form a contact medium 7.

[0088] When conducting the test for measuring the static friction coefficient at an inclined angle: Figure 1 As shown, a material 6 to be measured is placed at the starting position mark 51 of the movable platform 3, and then the distance sensor 84 is started, so that the transmitter and receiver of the sensor 84 are kept in a horizontal posture and aligned with the center of the material 6 to be measured, and calibrated according to the initial distance; then the driving mechanism drives the movable platform 3 to rotate counterclockwise around the rotating shaft 31 at a small angular velocity. When the movable platform 3 rotates to a certain angle, the material 6 to be measured rolls down, and the distance sensor 84 detects that the distance between it and the material 6 to be measured changes, the driving mechanism stops working, the movable platform 3 stops rotating, and remains at the current angle. Finally, it stands at the position facing the angle scale 81 to read and record the current angle of the movable platform 3. The material 6 to be measured is replaced, and the above steps are repeated for multiple measurements, and the inclination angle of the movable platform 3 is processed. The processed data is used for discrete element simulation analysis.

[0089] When conducting the tilt angle rolling friction coefficient test: Figure 1 and Figure 4-5 As shown, the driving mechanism drives the movable platform 3 to rotate to a preset angle (preferably 30° or 45°), clamps both ends of the material 6 to be tested at the starting position mark 51 of the movable platform 3 and then releases, and the material 6 to be tested rolls freely from the movable platform 3 to the stop position A4 on the extension platform 2, and the rolling distance of the material 6 to be tested on the extension platform 2 is recorded according to the distance scale 82. Repeat the measurement and record the rolling distance of the material 6 to be tested on the extension platform 2 according to the above steps, and the obtained data is processed for discrete element simulation analysis.

[0090] The collision recovery coefficient is a parameter that reflects the deformation recovery ability of an object during a collision. It is only related to the material of the colliding object and is defined as the ratio of the normal relative separation velocity to the normal relative approach velocity of the contact point of the object before and after the collision. When conducting a collision recovery coefficient measurement test: Figure 1 and Figure 2As shown, the camera is set up in the direction facing the height scale 83 and the camera starts recording. A material 6 to be measured is placed on the drop platform 971 in the drop mechanism, and its height is recorded as the starting height A1; then the button 94 is pressed, and the drop platform 971 shrinks to the right side of the fixed baffle 93, and the material 6 to be measured falls from the starting height A1 in a free fall state. After colliding with the contact medium 7 at the collision height A2, it rebounds. The rebound height A3 of the center of mass of the material 6 to be measured is recorded according to the imaging of the camera, and finally the ratio of the rebound height A3 to the starting height A1 is calculated to obtain the collision recovery coefficient between the materials. Repeat the above steps for multiple times to measure and record the rebound height A3 of the material 6 to be measured, and the obtained data is processed for discrete element simulation analysis.

[0091] Preferably, the starting height A1 is 30 cm.

[0092] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
