Description

Technical Field

[0001] The invention relates to the field of physical parameter detection of cigarette popping beads, and in particular to a weightless popping bead strength detection device. Background Art

[0002] The use of popping beads for tobacco flavoring has become a development direction for Chinese cigarettes. The diameter of the popping beads is generally in the range of (2.5-3.8) mm. The popping beads are used as a carrier for cigarette flavoring and are widely used in cigarette product development. The strength of the popping beads is an important physical indicator of popping bead cigarette products. Due to the differences in the production materials and production processes of the popping beads, the strength of the popping beads varies. The size of the popping bead strength directly affects the consumer's experience. If the strength is too high, it is difficult to pinch it, and if the strength is too low, it is easy to break during processing and packaging.

[0003] Existing bursting bead strength testing devices usually adopt a vertical structure with two parallel pressure plates at the top and bottom for applying pressure in the vertical direction. This method has a simple structure and is easy to operate. However, when high-precision measurement of bursting bead strength is required, the vertical structure does not include the gravity of the bursting bead itself. Due to the gravity of the bursting bead itself, the force on the lower pressure plate is added and the force on the upper pressure plate is subtracted, thus affecting the accuracy and authenticity of the bursting bead strength test data. Summary of the invention

[0040] like Figure 1 As shown, an embodiment of the present invention provides a weightless bursting bead strength detection device, which includes a base 1, a fixed base 2, a probe 3, a horizontal guide structure 8, a sliding structure 9, a grating ruler 10, a pressure head 12, a column 4, a lifting slider 5, a crossbeam 6, a fixture 7 and a negative pressure air source; wherein the fixed base 2 is arranged on the base 1; the probe 3 is fixedly arranged on the fixed base 2, and a first pressure sensor is embedded in the probe 3; the horizontal guide structure 8 is arranged on the base 1; the sliding structure 9 is slidably connected to the horizontal guide structure 8; the grating ruler 10 is arranged on the sliding structure 9; the pressure head 12 is arranged on the sliding structure 9, the pressure head 12 is aligned with the position of the probe 3, and a second pressure sensor is embedded in the pressure head 12; the column 4 is arranged on the base 1; the lifting slider 5 is slidably connected to the column 4 in the vertical direction; the crossbeam 6 is slidably connected to the lifting slider 5 in the horizontal direction; one end of the fixture 7 is connected to the crossbeam 6, and the other end of the fixture 7 is used to fix the bursting bead 14, and a through hole is arranged in the fixture 7; the negative pressure air source is connected to the through hole on the fixture 7.

[0041] During the working process, the fixture 7 can be connected to the negative pressure gas source first, and the explosive bead 14 to be tested can be placed on the fixture 7, and the negative pressure gas source can be started to provide negative pressure to tightly adsorb the explosive bead 14 on the fixture 7 to fix the explosive bead 14. Then, the lifting slide block 5 can be controlled by the first stepper motor to rise to a preset position along the column 4 so that the explosive bead 14 is aligned between the pressure head 12 and the probe 3; then the crossbeam 6 can be controlled by the second stepper motor to move in the direction close to the pressure head 12 to drive the explosive bead 14 to gradually approach the probe 3; when the explosive bead 14 contacts the probe 3, the first pressure sensor embedded in the probe 3 can detect the pressure and produce a change in the pressure value, and the crossbeam 6 is controlled to stop moving. In this embodiment, in order to ensure that the explosive bead 14 is in a state of slight contact with the probe 3 without excessively squeezing the explosive bead 14, a stop signal can be issued at the moment when the first pressure sensor produces a value change, and the second stepper motor controls the crossbeam 6 to stop moving according to the stop signal.

[0042] After the position adjustment of the bursting bead 14 is completed, the linear motor can be controlled to drive the sliding structure 9 to slide on the horizontal guide structure 8, so that the pressure head 12 gradually approaches the measuring head 3; wherein, the sliding structure 9 can be the mover of the linear motor, and the horizontal guide structure 8 can be the stator of the linear motor. Before the pressure head 12 contacts the bursting bead 14, the mover can be driven to move at a speed of 50 mm / min. When the pressure head 12 is about to contact the bursting bead 14, the mover is driven to move at a speed of 10 mm / min. When the pressure head 12 contacts the bursting bead 14, the second pressure sensor embedded in the pressure head 12 will produce a change in value. When the pressure value displayed by the second pressure sensor is 0.1N, the second pressure sensor can send a stop signal, and the linear motor stops the mover movement according to the stop signal, thereby achieving a slight contact between the pressure head 12 and the bursting bead 14.

[0043] Then, the negative pressure gas source can be cut off to cancel the adsorption of the bursting bead 14, so that the bursting bead 14 is supported on the fixture 7 only by its own gravity. At the same time, the bursting bead 14 is also slightly squeezed by the measuring head 3 and the pressure head 12 to be fixed.

[0044] After the bursting bead 14 is fixed by the probe 3 and the pressure head 12, the lifting slider 5 is driven downward along the column 4 to move the clamp 7 out from between the probe 3 and the pressure head 12, while the bursting bead 14 remains motionless due to the slight squeezing effect of the probe 3 and the pressure head 12.

[0045] It can be understood that, in order for the clamp 7 to be smoothly moved out from between the probe 3 and the pressure head 12 after the bursting bead 14 is squeezed and fixed by the probe 3 and the pressure head 12 , the diameter of the clamp 7 can be smaller than the diameter of the bursting bead 14 .

[0046] Then, the linear motor drives the sliding structure 9 to move in the direction of the probe 3 at a speed of 10 mm / min, so that the pressure head 12 squeezes the bursting bead 14 to deform. During the movement of the sliding structure 9, the grating ruler 10 can record the displacement information in real time, and the first pressure sensor in the probe 3 can record the pressure information of the bursting bead 14 in real time. The grating ruler 10 and the first pressure sensor can send the above displacement information and pressure information to the controller. When the bursting bead 14 is crushed, the linear motor stops running, and the controller can draw a pressure-displacement curve based on the pressure information and displacement information.

[0047] Therefore, compared with the prior art, the weightless bursting bead strength detection device provided in this embodiment realizes the fixation of the bursting bead 14 in the horizontal direction through the cooperation of the probe 3 and the pressure head 12, eliminates the influence of the gravity of the bursting bead 14 on the strength detection of the bursting bead 14, and realizes the accurate detection of the strength of the bursting bead 14 by drawing the pressure-displacement curve.

[0048] Furthermore, the detection device further comprises a support plate 11 , wherein the support plate 11 is fixedly disposed on the sliding structure 9 , and the pressure head 12 is disposed on the support plate 11 .

[0049] The support plate 11 is in the shape of a "T", specifically including a vertical plate and a horizontal plate. The horizontal plate is fixedly set on the sliding structure 9, one end of the vertical plate is fixedly connected to the horizontal plate, and the other end of the vertical plate extends away from the horizontal plate. The axis of the pressure head 12 is perpendicular to the extension direction of the vertical plate, so that the pressure head 12 can be set at a position with a certain height to align the pressure head 12 with the measuring head 3.

[0050] Furthermore, the detection device further includes a bracket 13, one end of which is connected to the crossbeam 6, and the other end of which is connected to the fixture 7. The plane where the bracket 13 and the crossbeam 6 are located is perpendicular to the plane where the bracket 13 and the fixture 7 are located, so that the fixture 7 can be sent to the position between the probe 3 and the pressure head 12 through the bracket 13, and the movement path of the sliding structure 9 can be avoided at the same time.

[0051] Furthermore, an end portion of the clamp 7 is provided with an arc surface, and the arc surface is recessed toward the center of the clamp 7 .

[0052] The arc surface can fit with the surface of the bursting bead 14. When the negative pressure gas source provides negative pressure, the bursting bead 14 can be tightly adsorbed onto the arc surface, so that no gap is generated between the bursting bead 14 and the arc surface, thereby ensuring the reliability of the adsorption and fixation of the bursting bead 14.

[0053] Furthermore, in order to facilitate disassembly, assembly and replacement of the clamp 7, the clamp 7 and the bracket 13 may be connected by threads.

[0054] Since the diameter of the bursting beads 14 has various specifications, in order to be able to adsorb and fix the bursting beads 14 of different specifications, a clamp 7 of corresponding specifications can be selected and used according to the specifications of the bursting beads 14.

[0055] Furthermore, the diameter of the pressure head 12 is greater than or equal to 16 mm, so that the pressure head 12 has a sufficiently large pressure area to absorb the error caused by the positioning of the bursting bead 14; in addition, the diameter of the probe 3 can be larger than the diameter of the pressure head 12, so that the probe 3 has a sufficiently large contact area to withstand the squeezing of the bursting bead 14 by the pressure head 12, thereby improving the strength of the entire structure.

[0056] Furthermore, the diameter of the through hole is 0.2 mm to 0.3 mm. In this embodiment, the diameter of the through hole is preferably 0.2 mm.

[0057] Furthermore, in order to facilitate the sliding of the cross beam 6 relative to the lifting slider 5 and ensure the stability of the cross beam 6 when sliding, a sliding hole can be provided in the lifting slider 5, and the cross beam 6 is slidably set in the sliding hole.

[0058] Furthermore, a limit portion can be provided on the column 4, which can be used to prevent the lifting slider 5 from rising excessively, causing the bursting bead 14 to fail to be positioned between the probe 3 and the pressure head 12, thereby easily causing a rigid collision between the pressure head 12 and the probe 3 and damaging the device.

[0059] The weightless bursting bead strength detection device provided in the embodiment of the present invention fixes the bursting bead in the horizontal direction through the cooperation of the measuring head and the pressure head, eliminates the influence of the bursting bead gravity on the bursting bead strength detection, and realizes accurate detection of the bursting bead strength by drawing the pressure-displacement curve.
