Description

Technical Field

[0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a filter rod bonding strength detector. Background Art

[0002] The filter rod is a component of a cigarette, and plays a role in partially filtering harmful substances or other particulate matter in the smoke when people smoke cigarettes. There are many indicators to measure the quality of filter rod products, and its bonding strength is one of the important indicators. When the filter rod is affected by a large external force during transportation or cigarette rolling, the composite filter rod may have the quality problem of turning around. The main reasons are as follows: 1. During the filter rod molding process, the center glue of the composite filter rod is not applied or the center glue is applied intermittently and incoherently; 2. The width of the center glue is narrow or the amount is small, resulting in insufficient bonding strength between the base rod and the molding paper. During the cigarette rolling process, unqualified filter rod bonding strength will cause the filter rod to turn around, resulting in serious quality accidents. Therefore, it is of great practical significance and promotion and application value to test the bonding strength of the composite filter rod to check whether the bonding strength of the base rod meets the qualified indicators.

When installed, the upper shearing mounting plate 02404 and the lower shearing mounting plate 02405 are relatively installed on the double guide rod 02407, so that when the double guide rod 02407 rotates, the upper shearing mounting plate 02404 and the lower shearing mounting plate 02405 can approach or move away at the same time, so as to meet the shearing module 02400 to perform the action of clamping and releasing.

[0038] The upper clamping scissors 02402 are fixedly mounted on the upper clamping scissors mounting plate 02404, and the lower clamping scissors 02403 are fixedly mounted on the lower clamping scissors mounting plate 02405. It should be noted that the clamping scissors structure composed of the upper clamping scissors 02402 and the lower clamping scissors 02403 is a well-known sharp-mouthed tweezer structure with clamping ability. The clamping scissors motor 02409 is installed above the clamping scissors base 02401 and is connected to the double guide rod 02407 through the coupling 02408 to drive the double guide rod 02407 to rotate to manipulate the upper clamping scissors 02402 and the lower clamping scissors 02403 to perform a clamping action.

The upper proximity switch 02410 is installed above a certain distance from the upper shear clamp mounting plate 02404, and the lower proximity switch 02411 is installed below a certain distance from the lower shear clamp mounting plate 02405. They are used to detect the operating positions of the upper shear clamp mounting plate 02404 and the lower shear clamp mounting plate 02405, respectively, to prevent the upper shear clamp mounting plate 02404 and the lower shear clamp mounting plate 02405 from moving beyond a safe range.

[0040] See also Figure 4 and Figure 5 The hopper 03000 of the embodiment of the present invention comprises a hopper support 03100, a material box 03200, a roller 03300, a turntable 03400, a screw-in 03500, a material sorter 03600 and a hopper motor 03700. The hopper support 03100 is fixedly mounted on the equipment workbench 00000 and is located in the moving direction of the mobile platform 01000 close to the detection device 02000; the material box 03200 is supported by the hopper support 03100 and is clamped with it, and a material sorter 03600 is installed inside the material box 03200, so that the material sorter 03600 can move along the direction of the mobile platform 01000, so that the filter rod to be tested entering the hopper 03000 from the material box 03200 keeps both ends aligned for the next operation. In this embodiment, a connecting hole is opened on the material box 03200 to cooperate with the moving rod on the material sorter 03600 to realize the movement of the material sorter 03600 on the material box 03200; accordingly, the side of the material sorter 03600 that contacts the end face of the filter rod to be tested is a baffle arranged perpendicular to the horizontal plane to align the end face of the filter rod to be tested; the material in the material box 03200 is aligned by manually pushing the material sorter 03600.

[0041] The turntable 03400 is installed below the material box 03200 to receive the filter rod to be tested that falls from the material box 03200 . There are multiple grooves on the turntable 03400 to adapt to the filter rod to be tested. One end of the turntable 03400 is rotatably installed in the hopper bracket 03100, and the other end is connected to the screw-in 03500. The screw-in 03500 has two left and right screw-in parts, and the two screw-in parts are respectively connected to the turntable 03400 and the roller 03300. Correspondingly, a feeding trough matching the number of grooves on the turntable 03400 is opened on the roller 03300. The feeding trough and the grooves work together to drive the filter rod to be tested to rotate. The other end of the roller 03300 is connected to the hopper motor 03700. The hopper motor 03700 drives the turntable 03400 and the roller 03300 to rotate the filter rod to be tested that enters from the material box 03200 to the clamping device 04000 below for fixation.

[0042] In this embodiment, the turntable 03400 is provided with grooves of large and small sizes for selecting and limiting the circumferential specifications of the filter rod to be tested. The large and small sizes correspond to ordinary filter rods and ultrafine filter rods respectively. The grooves of the two specifications are evenly staggered and distributed on the outer circumference of the turntable 03400, and the number is 5, and each groove of the same size is evenly distributed. Correspondingly, the number of the feeding grooves on the outer circumference of the roller 03300 is 5, and the specification is adapted to the circumferential size of the ordinary filter rod. When in use, first determine the specifications of the filter rod to be tested, seal the grooves of the specifications that are not used temporarily with a model or a cover plate, and manually adjust the screw-on parts at both ends of the screw-on 03500 to align the grooves on the turntable 03400 with the feeding grooves on the roller 03300, so that the material to be tested falls into the grooves and the feeding grooves at the same time.

[0043] A clamping baffle 03800 and a proximity switch 03900 are installed on the outer periphery of the turntable 03400. The clamping baffle 03800 is fixedly installed on the hopper bracket 03100, and the proximity switch 03900 is installed on the clamping baffle 03800. In this embodiment, the clamping baffle 03800 is a U-shaped thin plate structure, and its U-shaped mouth is installed on the outer periphery of the turntable 03400 with an upward direction, so as to prevent the filter rod to be tested placed in the groove of the turntable 03400 from falling during the rotation of the turntable 03400; the proximity switch 03900 is installed on the clamping baffle 03800 and is located on the central axis of the turntable 03400 and the clamp device 04000 that fixes the position of the filter rod to be tested, so as to detect the position information of the filter rod to be tested.

[0052] Preferably, the force gauge 02300 may be a strain sensor or a piezoelectric force sensor.

[0053] Please refer again Figure 1 and Figure 2 The use of the present invention includes a debugging step and a formal use. Before the formal use, the present invention needs to be debugged to ensure that the present invention can safely and reliably complete the designated detection work when it is formally used.

[0054] During debugging, disconnect the power supply, determine the specifications of the filter rod to be tested, screw the screws at both ends of the screw-in device 03500 to align the groove on the turntable 03400 that meets the specifications of the filter rod to be tested with the feeding slot on the roller 03300, put the filter rod to be tested into the groove and the feeding slot, manually rotate the turntable 03400 to move the filter rod to be tested in the groove to the designated detection point, manually adjust the position of the clamp device 04000 to make the clamp 04300 face the turntable 03400; manually screw the upper clamp 02 402 and the lower clamp 02403 make their pointed ends fit together, manually adjust the mobile platform 01000, the Y-axis regulator 02100 and the Z-axis regulator 02200, so that the pointed ends of the upper clamp 02402 and the lower clamp 02403 fit together coincide with the center line of the filter rod to be tested in the turntable 03400, adjust the mobile platform 01000 to make the detection device 02000 away from the filter rod to be tested and separate the upper clamp 02402 and the lower clamp 02403 that are fitted together, and complete the debugging;

[0055] When it is officially used, close the protective cover 05000, put the filter stick to be tested into the material box 03200, manually adjust the material sorter 03600 to align the two end surfaces of the filter stick to be tested in the material box 03200, and press the start button 08000; the filter stick to be tested falls into the turntable 03400, and is brought to the designated detection point under the rotation of the turntable 03400, and the proximity switch 03900 installed on the clamping baffle 03800 detects that the filter stick to be tested has reached the designated position, and sends a signal to the PLC system. After receiving the processed signal, the PLC system drives the clamp device 04000 to move the clamp 04300 to move closer to the turntable 03400, and the clamp 04300 cooperates with the groove on the turntable 03400 to fix one end of the filter stick to be tested. Then the detection device 02000 starts to work, and the mobile platform 01000 moves towards the unfixed end of the filter rod to be tested under the signal of the PLC until the upper clamp 02402 and the lower clamp 02403 are inserted into the filter rod to be tested to a specified depth; then the clamp motor 02409 starts to work, driving the double guide rod 02407 to rotate, and the double guide rod 02407 drives the upper clamp 02402 and the lower clamp 02403 to approach each other, thereby clamping the wire bundle in the filter rod to be tested, thereby clamping the filter rod to be tested; then the detection device 02000 moves in the direction away from the filter rod to be tested, and at the same time, the other end of the filter rod to be tested is fixed by the turntable 03400 and the clamp 04300. At this time, one end of the filter rod to be tested is pulled and the other end is fixed to simulate the process of the filter rod falling off outward; the maximum pulling force when the filter rod to be tested is pulled by the dynamometer 02300, that is, the bonding strength of the filter rod to be tested.
