Technical Field
[0001] This utility model relates to the field of cigarette testing technology, specifically, to a composite device for cigarette weighing and draw resistance testing. Background Technology
[0002] The performance parameters of cigarettes are tested in a wide range of ways, with relevant national standards as a reference. They mainly include physical and chemical indicators. Among them, physical indicators are tested through a series of physical measurement methods, and the test results have a significant impact on the quality of the finished cigarettes.
[0003] The national standard GB / T22838.5-2009 "Determination of Physical Properties of Cigarettes and Filter Rods" specifies the determination of cigarette properties in 18 parts, including multiple parameters such as length, mass, circumference, hardness, ventilation rate, and draw resistance.
[0004] Among them, there are dedicated suction resistance testing devices available for suction resistance testing, while quality testing is usually carried out using high-precision scales.
[0005] Although the aforementioned national standards specify the performance requirements of available equipment for testing the above parameters, as well as the relevant testing standards, they do not consider automation methods and only provide independent guidance for each part.
[0006] In the application of empty cigarette dispensers, the tobacco to be tested is filled into empty cigarettes to make temporary test cigarettes for evaluation. Therefore, it is necessary to test the above parameters on the temporarily manufactured test cigarettes. The compliance of the cigarettes is a prerequisite for subsequent evaluation of the tobacco.
[0007] Among these issues, the main problem that needs to be solved is how to automate the weighing and suction resistance detection processes to simplify the detection steps and improve efficiency.
[0008] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content
[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a combined device for weighing and detecting the resistance of cigarettes, which can automate the weighing and resistance detection of cigarettes.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is: a composite device for weighing and detecting the suction resistance of cigarettes, including a cigarette inlet channel, a cigarette outlet mechanism, a cigarette slide, a cigarette receiving rack, a weighing component, a suction resistance detection component, and a cigarette clamping robot.
[0011] The smoke inlet channel is a channel that accommodates the axial movement of a single cigarette, and a smoke return groove is provided at the tail end of the smoke inlet channel;
[0012] The smoke removal mechanism includes a smoke removal lifting assembly and a smoke removal arm. The smoke removal arm is disposed in the smoke removal groove. The smoke removal lifting assembly lifts the smoke removal arm by driving it up and down, thereby lifting the cigarette out from the tail end of the smoke inlet channel.
[0013] The cigarette slide is an inclined slide, located at the front of the end of the smoke inlet channel, and is used to receive cigarettes lifted out from the end of the smoke inlet channel.
[0014] The cigarette receiving rack is located at the upper end of the weighing assembly and below the cigarette slide, and is used to receive cigarettes that slide down from the cigarette slide.
[0015] The suction resistance detection component is located on one side of the weighing component;
[0016] The cigarette-holding robot is located on the other side of the weighing assembly and is used to hold one end of the cigarette and feed the cigarette into the suction resistance detection assembly.
[0017] Based on the above, the cross-section of the smoke inlet channel is a U-shaped groove.
[0018] Based on the above, the smoke trough is a plurality of parallel troughs formed at the tail end of the smoke inlet channel, the troughs being located at the bottom of the smoke inlet channel and penetrating the rear side of the smoke inlet channel.
[0019] Based on the above, the upper end face of the part of the cigarette ejector arm that enters the cigarette ejector groove is set as a forward-inclined end face, which is used to provide forward rolling potential energy after the cigarette is lifted out of the smoke channel.
[0020] Based on the above, limiting baffles are provided at both ends of the cigarette slide, and the spacing between the limiting baffles is greater than the length of the cigarette.
[0021] Based on the above, a V-shaped groove is provided at the top of the cigarette receiving rack, and the overall length of the V-shaped groove is less than the length of the cigarette, so that after the cigarette falls into the cigarette receiving rack, the end near the cigarette holding robot is suspended in the air.
[0022] Based on the above, the cigarette robot includes a horizontal clamping mechanism, a transverse movement mechanism, and a longitudinal movement mechanism, wherein the clamping end of the horizontal clamping mechanism is provided with a U-shaped clamp that matches the cigarette.
[0023] Based on the above, a weighing lifting mechanism is provided at the bottom of the weighing component for driving the weighing component to lift as a whole.
[0024] Based on the above, the clamping hole of the suction resistance detection component is at the same height as the clamping height of the cigarette robot.
[0025] Based on the above, it also includes a collection trough, which is located within the stroke range of the cigarette robot and is used to collect the tested cigarettes.
[0026] This utility model has substantial features and progress compared to the prior art. Specifically, in terms of operation logic, this utility model uses a cigarette ejection mechanism to lift and eject the cigarette, uses a cigarette slide to allow the cigarette to enter the cigarette receiving rack from the cigarette inlet channel, uses a weighing component to weigh the cigarette in real time, and uses a robotic arm and a suction resistance detection component to transfer the cigarette from the cigarette receiving rack to the suction resistance detection component. Through the cooperation of various mechanisms, the entire system realizes the automated and continuous weighing and suction resistance detection of the cigarette. Attached Figure Description

[0032] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0033] like Figures 1-4 As shown, a combined device for weighing and detecting the suction resistance of cigarettes includes a cigarette inlet channel 1, a cigarette outlet mechanism 2, a cigarette slide 3, a cigarette receiving rack 4, a weighing component 5, a suction resistance detection component 6, and a cigarette clamping robot 7.
[0034] The smoke inlet channel 1 is a channel for accommodating the axial movement of a single cigarette. Its cross-section is a U-shaped groove. A push rod mechanism can be configured upstream to realize the movement of the cigarette along the smoke inlet channel 1. A smoke outlet groove 11 is provided at the tail end of the smoke inlet channel. The smoke outlet groove 11 consists of several parallel grooves opened at the bottom of the smoke inlet channel 1. The grooves extend to and through the rear end of the smoke inlet channel 1 so that the smoke outlet arm 21 of the smoke outlet mechanism 2 can enter the smoke outlet groove 11.
[0035] The cigarette removal mechanism 2 includes a cigarette removal lifting assembly 22 and a cigarette removal arm 21. The cigarette removal arm 21 is disposed in the cigarette removal groove 11. The cigarette removal lifting assembly 22 lifts the cigarette 8 from the tail end of the cigarette inlet channel 1 by driving the cigarette removal arm 21 to rise and fall. In this embodiment, the cigarette removal lifting assembly 22 is a lifting cylinder or electric cylinder, and is equipped with a limit sensor for the upper and lower positions to constrain the lifting stroke of the cigarette removal arm 21. The upper end face of the portion of the cigarette removal arm 21 located in the cigarette removal groove 11 is set as a forward inclined slope. When the cigarette 8 is raised beyond the cigarette inlet channel 1, the inclined slope can provide the potential energy for the cigarette 8 to roll forward, so that the cigarette 8 can smoothly enter the cigarette slide 3.
[0036] The cigarette slide 3 is an inclined slide, located at the front of the end of the cigarette inlet channel 1, and is used to receive the cigarettes 8 lifted out from the end of the cigarette inlet channel 1. To prevent the cigarettes from deviating from their current direction, limiting baffles 31 are respectively set at the left and right ends of the cigarette slide 3, and the distance between the limiting baffles 31 is greater than the length of a single cigarette.
[0037] The cigarette receiving rack 4 is located at the upper end of the weighing component 5 and below the cigarette slide 3. It is used to receive the cigarettes 8 that slide down from the cigarette slide 3. The upper end of the cigarette receiving rack 4 is a V-shaped groove, and the groove depth can be appropriately increased to prevent the rolling cigarettes 8 from slipping off due to inertia.
[0038] The cigarette receiving rack 4 is installed on the weighing assembly and can be regarded as the pallet of the weighing assembly. When weighing the cigarettes 8, a tare operation needs to be performed.
[0039] The lower end surface of the cigarette holder 4 is flat and can be fixed to the supporting surface of the weighing component by means of bonding, welding, magnetic attraction, etc.
[0040] To avoid spatial interference between the weighing component and the cigarette receiving rack 4 and subsequent clamping and transfer actions, a weighing lifting mechanism 9 is provided at the bottom of the weighing component 5 to drive the weighing component 5 to lift as a whole.
[0041] The suction resistance detection component 6 is located on one side of the weighing component 5. In this embodiment, it is located on the left side. The suction resistance detection component 6 is an existing detection device. It achieves a seal at a specific position by fixing the cigarette mouthpiece end with a rubber airbag ring. Then, it measures the suction resistance of the cigarette by connecting to a smoking machine, differential pressure gauge and other special equipment. Therefore, at the execution level, the required operation is to transfer the cigarette 8 from the cigarette receiving rack 4 to the hole of the suction resistance detection component 6.
[0042] The cigarette clamping robot 7 is located on the other side of the weighing component 5. In this embodiment, it is located on the right side and is used to clamp one end of the cigarette 8 and send the mouthpiece end of the cigarette 8 into the hole of the suction resistance detection component 6.
[0043] To facilitate the rapid clamping of cigarettes by the cigarette-holding robot 7 and reduce spatial interference, the overall length of the cigarette receiving rack 4 is designed to be shorter than the cigarette, with the shorter part closer to the side of the cigarette-holding robot 7. This ensures that after the cigarette falls into the cigarette receiving rack 4, the end closest to the cigarette-holding robot 7 is suspended in the air.
[0044] The clamping hole of the suction resistance detection component 6 is at the same height as the clamping height of the cigarette robot 7. The cigarette robot 7 includes a horizontal clamping mechanism 71, a transverse movement mechanism 72, and a longitudinal movement mechanism 73. The transverse movement mechanism 72 and the longitudinal movement mechanism 73 are two mutually perpendicular moving mechanisms in the horizontal plane.
[0045] The horizontal clamping mechanism 71 has a U-shaped clamping end that matches the cigarette. After the cigarette is clamped in the suspended position, the weighing component descends to make room, and the cigarette robot arm 7 then horizontally sends the cigarette into the hole of the suction resistance detection component 6.
[0046] To prevent the cigarettes from being left lying around after testing, a collection trough 10 is also included. The collection trough 10 is located within the stroke range of the cigarette robot arm 7 and is used to collect the cigarettes 8 after testing.
[0047] Specific work process:
[0048] Taking the process of filling an empty chimney with smoke as an example, after the upstream filling is completed, the smoke sticks are pushed one by one to the end of the smoke inlet channel 1 by a horizontal pushing mechanism. The rhythm needs to be executed according to the rhythm of the detection.
[0049] After reaching the end of the smoke inlet channel 1, the smoke removal mechanism 2 drives the smoke removal arm 21 to rise, raising the cigarette stick 8 until it exceeds the side wall of the smoke inlet channel 1. Then, under the action of the inclined surface of the smoke removal arm 21, it rolls forward and enters the cigarette receiving rack 4 through the guide of the cigarette slide 3.
[0050] After the weighing component weighs the cigarette in real time, the cigarette clamping robot 7 clamps the tail end of the cigarette 8 from the right end. Then the weighing component 5 lowers to a certain height to make room, and the cigarette clamping robot 7 horizontally sends the cigarette into the hole of the suction resistance detection component 6 and releases it to perform suction resistance detection.
[0051] After the suction resistance test is completed, the cigarette holding robot 7 then holds the cigarette 8 and transfers it to the collection tank 10, waiting for the next cigarette to be tested.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
