Description

Technical Field

[0001] This utility model relates to the field of tobacco testing technology, specifically to a rapid testing platform for online batch testing of cigarette filter rods. Background Technology

[0002] With the surge in demand for automated factories (lights-out factories), the need for automated testing methods for cigarette sticks / filters is extremely urgent.

[0003] Currently, the testing methods for cigarettes / filters at the production end mostly involve sampling, where staff randomly select a portion of cigarettes for testing. The main testing equipment is a comprehensive testing bench, which checks at a rate of no more than 6 cigarettes per minute. Moreover, the comprehensive testing bench needs to test the weight, length, circumference, draw resistance, ventilation, and hardness of the cigarettes / filters sequentially, which is time-consuming.

[0004] In the process of automation transformation, the manual extraction of cigarettes can be solved by various robotic arms or other automated solutions, which is a relatively easy problem to solve. However, how to improve testing efficiency is one of the main obstacles at present.

[0005] Since the speed of cigarette rolling machines and filter rod forming machines usually reaches more than 5,000 cigarettes / minute, or even more than 10,000 cigarettes / minute, the testing speed of the cigarette / filter rod integrated testing platform is far from keeping up with the production speed. Moreover, there is an order of magnitude difference between the number of samples tested and the number of productions, making it difficult to match the current production rhythm and reflect the quality of the cigarettes currently produced.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an online batch testing platform for cigarette filter rods that can quickly measure the draw resistance / ventilation rate of cigarettes on the production line and meet the sampling inspection requirements of high-speed production lines.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a rapid testing platform for online batch testing of cigarette filter rods, including a horizontally movable feeding mechanism and several testing units;

[0009] The material feeding mechanism reciprocates in the horizontal direction. The material feeding mechanism includes a hopper and a vertical slide rail disposed below the hopper. The bottom end of the vertical slide rail is the material feeding port.

[0010] Several test units are arranged in a straight line below the movement trajectory of the unloading mechanism. The test chamber of each test unit is a vertical channel formed within the test unit, with the top of the vertical channel being the inlet and the bottom being the outlet.

[0011] As the feeding mechanism reciprocates horizontally, the feeding port passes through the inlet at the top of each test unit one by one for feeding.

[0012] Based on the above, several of the test units constitute a series of test units with identical functions.

[0013] Based on the above, the test unit is a ventilation rate test unit or a suction resistance test unit.

[0014] Based on the above, the test unit is a combined test unit for ventilation rate and suction resistance.

[0015] Based on the above, the ventilation rate test unit or suction resistance test unit includes a test head, a test chamber, a negative pressure system, and a latex clamp. The latex clamp is ring-shaped and distributed vertically in the test chamber. The negative pressure system is used to drive the latex clamp to open or close. The test head is provided with a passage and test components for testing ventilation rate or suction resistance.

[0016] Based on the above, the ventilation rate and suction resistance composite test unit includes a test head, a test chamber, a negative pressure system, and a latex clamp. The latex clamp is ring-shaped and distributed vertically in the test chamber. The negative pressure system is used to drive the latex clamp to open or close. The test head is provided with a passage and test components for testing ventilation rate and suction resistance.

[0017] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model decomposes the numerous test units in the comprehensive test bench and can be designed into multiple functional modules for detecting single parameter information. Each functional module includes only a material feeding mechanism capable of reciprocating horizontal movement and several test units for detecting single parameters, such as ventilation rate test unit or suction resistance test unit. This allows the entire module to efficiently perform rapid and simultaneous multi-item testing of single parameters, greatly improving testing efficiency and meeting the sampling inspection and automation transformation needs of composite automated production lines.

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0023] Example 1

[0024] like Figures 1-3 As shown, a rapid testing platform for online batch testing of cigarette filter rods includes a horizontally movable feeding mechanism 1 and several testing units 2.

[0025] The feeding mechanism 1 reciprocates in the horizontal direction. The feeding mechanism 1 includes a hopper 11 and a vertical slide 12 disposed below the hopper 11. The bottom end of the vertical slide 12 is the feeding port. The docking area between the cone-shaped opening below the hopper 11 and the vertical slide 12 can be designed as a gradually narrowing structure so that the cigarette can gradually change from horizontal to vertical as it slides through the layers, and finally enter the vertical slide 12.

[0026] Several test units 2 are arranged in a straight line below the movement trajectory of the feeding mechanism. The test cavity 21 of the test unit 2 is a vertical channel formed in the test unit. The top end of the vertical channel is the inlet and the bottom end is the outlet.

[0027] As the feeding mechanism 1 reciprocates horizontally, the feeding port passes through the inlet at the top of each test unit one by one for feeding. In this embodiment, several test units 2 are a row of test units with the same function.

[0028] During the feeding process, the top of the test unit 2 can be spliced ​​into a smooth plane to avoid damage to the cigarettes during horizontal sliding. Alternatively, an automatic baffle can be installed at the feeding port. When the device moves above the inlet of the test unit 2, the baffle opens to allow the cigarettes to fall into the test chamber 21.

[0029] The test unit is either a ventilation rate test unit or a suction resistance test unit. Alternatively, the test unit may be a combined ventilation rate and suction resistance test unit.

[0030] In this embodiment, a combined ventilation rate and suction resistance test unit is used as an example for illustration. Its structure is roughly equivalent to the single-function ventilation rate test unit or suction resistance test unit, and it can be used as an example for illustration.

[0031] Specifically, its structure includes a test head 22, a test chamber 21, a negative pressure system 23, and a latex clamp 24. The latex clamp 24 is ring-shaped and is vertically distributed in the test chamber 21. The negative pressure system 23 is used to drive the latex clamp 24 to open or close. The test head 22 is provided with a passage and test components for testing ventilation rate or suction resistance.

[0032] Specifically, the test head is essentially a traditional device used to test suction resistance and ventilation rate. Its structure is existing technology. The latex clamp 24 includes a cylindrical latex film and a latex film fixing frame. The latex film fixing frame has a negative pressure hole. The deformation of the latex film can be controlled by the negative pressure system, thereby changing the closing diameter of the latex clamp 24 and realizing the function of clamping or releasing the cigarette to be tested.

[0033] Its main innovation lies in integrating the passage and components used to test ventilation rate or suction resistance into the test head 22. The structure of the test head 22 is modularized, the volume is increased, but the components themselves are unchanged. They all utilize the condition of forming a flow rate of 17.5 ml / s in the suction passage to observe the changes in flow rate and pressure difference.

[0034] 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.
