Description

Technical Field

[0001] The utility model relates to the technical field of cigarette experimental equipment, in particular to a negative pressure quantitative adsorption tobacco extraction system. Background Art

[0002] In the cigarette production process, smokers' satisfaction and comfort need to be considered while ensuring the safety of tobacco products. Studies have shown that the intrinsic qualities of cigarettes, such as the ratio of tobacco product ingredients, tobacco filling density, and filling uniformity, have an impact on the aroma quality and the release of harmful components in the smoke. Therefore, in order to improve the intrinsic quality of cigarettes, laboratory personnel of tobacco companies will change the ratio of tobacco products and develop new formula tobacco products. When developing new formula tobacco products, it is necessary to prepare cigarettes with well-proportioned formula tobacco and conduct smoking aroma tests. However, since it is an experimental test sample, the amount of formula tobacco is small, and it is impossible to prepare formula cigarettes on the cigarette production line.

[0003] Among them, the preparation and testing of formula cigarettes have high requirements for the weight accuracy of tobacco. Currently, most laboratory personnel weigh tobacco manually, which is labor-intensive, has high labor costs, and has extremely low weighing efficiency and poor weighing accuracy, resulting in low filling efficiency and may also contaminate tobacco, affecting test results.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a negative pressure quantitative adsorption tobacco extraction system. The utility model has high tobacco extraction efficiency, high tobacco weight accuracy, improved cigarette filling efficiency, high degree of mechanization, low labor intensity, low labor cost, avoids tobacco contamination, and ensures test results.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a negative pressure quantitative adsorption tobacco extraction system, including a linear reciprocating drive mechanism, a tobacco storage box with an open top, an adsorption component, a lifting mechanism, a tobacco beating and cutting mechanism and a weighing tray. The tobacco storage box, the tobacco beating and cutting mechanism and the weighing tray are arranged at intervals along a straight line on the same side of the linear reciprocating drive mechanism. The straight line where the tobacco storage box, the tobacco beating and cutting mechanism and the weighing tray are located is parallel to the movement direction of the linear reciprocating drive mechanism. The adsorption component is installed on the lifting mechanism and rises and falls under the drive of the lifting mechanism. The lifting mechanism is installed on the linear reciprocating drive mechanism. The linear reciprocating drive mechanism drives the lifting mechanism to perform linear reciprocating motion, so that the lifting mechanism drives the adsorption component to reciprocate between the tobacco storage box and the weighing tray and pass through the tobacco beating and cutting mechanism. The adsorption component is externally connected to a negative pressure suction device.

[0007] Based on the above, the adsorption assembly includes an adsorption box with an open bottom, the lower port of the adsorption box is covered and fixedly installed with an adsorption mesh plate, the top of the adsorption box is provided with a suction port connected to the interior of the adsorption box, and the interior of the adsorption box is fixedly installed with an air distribution plate parallel to the adsorption mesh plate, the air distribution plate is evenly distributed with air holes, and the suction port is connected to the negative pressure suction device through a suction hose.

[0008] Based on the above, the cigarette beating and cutting mechanism includes a cigarette beating motor, a frame and a circular cutter. The frame is arranged between the tobacco storage box and the weighing tray. The cigarette beating motor is vertically fixed on the frame. The circular cutter is co-centeringly fixed on the upper end of the motor shaft of the cigarette beating motor and is located between the tobacco storage box and the weighing tray.

[0009] Based on the above, the height of the circular cutter is higher than the heights of the tobacco storage box and the weighing tray.

[0010] Based on the above, the linear reciprocating drive mechanism is a linear module including a slide.

[0011] The lifting mechanism includes a cylinder bracket, a slide cylinder and a lifting bracket. The bottom of the cylinder bracket is fixedly installed on the slide seat of the linear reciprocating drive mechanism. The slide cylinder is vertically fixedly installed on the cylinder bracket. The lifting bracket is horizontally arranged. One end of the lifting bracket is fixedly installed on the slide top plate of the slide cylinder. The other end of the lifting bracket is a cantilever end above the tobacco storage box and is fixedly connected to the upper side of the adsorption box.

[0012] Based on the above, a blade shaft is coaxially fixedly installed on the upper end of the motor shaft of the smoke suppressor motor, a cutter disc is fixedly installed on the upper end of the blade shaft by a knurled high-head screw, a circular cutter is coaxially arranged between the cutter disc and the upper end of the blade shaft, the knurled high-head screw passes through the center hole of the circular cutter, and the cutter disc presses the circular cutter to fix the upper end of the blade shaft.

[0013] Based on the above, the width of the weighing tray is greater than the width of the adsorption box.

[0014] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model controls the lifting and lowering of the adsorption component through a lifting mechanism, provides negative pressure through a negative pressure suction device, uses the adsorption component to adsorb a certain weight of tobacco layer from the tobacco storage box, and then drives the adsorption component to move toward the weighing tray through a linear module. When the adsorption component passes through the tobacco beating and cutting mechanism, the bottom of the tobacco layer is cut flat, ensuring that the tobacco adsorbed and extracted each time has the same thickness and weight and meets the required weight. When the adsorption component reaches above the weighing tray, the negative pressure suction device is closed to make the tobacco fall onto the weighing tray, and the weighing tray transfers the tobacco to the next process for pouring out. Then, the weighing tray, the linear module and the adsorption component are reset, and the above operation is repeated. Then, the weighing tray can receive the same weight of tobacco again, with high efficiency in extracting tobacco and high precision in weight of extracted tobacco, improved cigarette filling efficiency, high degree of mechanization, low labor intensity, low labor cost, avoidance of tobacco pollution, and guaranteed test results.

[0015] After working for a period of time, in order to ensure the adsorption effect, the negative pressure suction device is controlled to blow air in the reverse direction to clean the adsorption mesh plate of the adsorption component to achieve self-cleaning. The air distribution plate of the adsorption component ensures uniform negative pressure on the adsorption mesh plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0026] Example 1

[0027] like Figure 1-8 As shown, the negative pressure quantitative adsorption tobacco extraction system includes a linear reciprocating drive mechanism, a tobacco storage box 1 with an open top, an adsorption component, a lifting mechanism, a tobacco beating and cutting mechanism, and a weighing tray 2. The tobacco storage box 1, the tobacco beating and cutting mechanism, and the weighing tray 2 are arranged in a straight line at intervals on the same side of the linear reciprocating drive mechanism. The straight line where the tobacco storage box 1, the tobacco beating and cutting mechanism, and the weighing tray 2 are located is parallel to the movement direction of the linear reciprocating drive mechanism. The adsorption component is installed on the lifting mechanism and is lifted and lowered under the drive of the lifting mechanism. The lifting mechanism is installed on the linear reciprocating drive mechanism. The linear reciprocating drive mechanism drives the lifting mechanism to perform linear reciprocating motion, so that the lifting mechanism drives the adsorption component to reciprocate between the tobacco storage box 1 and the weighing tray 2 and pass through the tobacco beating and cutting mechanism. The adsorption component is externally connected to a negative pressure suction device. The negative pressure suction device is not shown in the figure. The negative pressure suction device is a device that generates negative pressure such as a vacuum pump or a negative pressure fan.

[0028] The adsorption assembly includes an adsorption box 3 with an open bottom, the lower port of the adsorption box 3 is covered and fixedly installed with an adsorption mesh plate 4, the top of the adsorption box 3 is provided with a suction port 5 connected to the interior of the adsorption box 3, and the interior of the adsorption box 3 is fixedly installed with an air distribution plate 6 parallel to the adsorption mesh plate 4, and the air distribution plate 6 is evenly distributed with air holes 7, and the suction port 5 is connected to the negative pressure suction device through a suction hose.

[0029] The cigarette beating and leveling mechanism includes a cigarette beating motor 8, a frame 9 and a circular cutter 10. The frame 9 is arranged between the tobacco storage box 1 and the weighing tray 2. The cigarette beating motor 8 is vertically fixed on the frame 9. The circular cutter 10 is co-centrally fixed on the upper end of the motor shaft of the cigarette beating motor 8 and is located between the tobacco storage box and the weighing tray. The height of the circular cutter 10 is higher than the height of the tobacco storage box 1 and the weighing tray 2.

[0030] The linear reciprocating drive mechanism 11 is a linear module including a slide. The linear reciprocating drive mechanism 11 in this embodiment adopts a ball screw type linear module, and in other embodiments, it can also be a synchronous belt type or a linear motor type linear module.

[0031] A blade shaft is coaxially fixedly mounted on the upper end of the motor shaft of the smoke-removing motor 8, and a cutter disc is fixedly mounted on the upper end of the blade shaft by a knurled high-head screw. A circular cutter 10 is coaxially arranged between the cutter disc and the upper end of the blade shaft, and the knurled high-head screw passes through the center hole of the circular cutter. The cutter disc presses the circular cutter 10 to fix the upper end of the blade shaft.

[0032] The width of the weighing tray 2 is greater than the width of the adsorption box 3 .

[0033] When the present embodiment starts working, tobacco is filled in the tobacco storage box 1, and the adsorption box 3 is located above the tobacco storage box 1. Then, the adsorption box 3 is lowered into the tobacco storage box 1 through the lifting mechanism, the negative pressure suction device is started and a certain negative pressure is set, and negative pressure is generated in the adsorption box 3. Due to the setting of the air balancing plate 6, the negative pressure on the adsorption mesh plate 4 is guaranteed to be uniform, and the lower surface of the adsorption mesh plate 4 uniformly adsorbs a certain weight of tobacco layer, and then the adsorption box 3 is raised to a set height through the lifting mechanism and taken out of the tobacco storage box 1. After that, the adsorption box 3 is driven to move toward the weighing tray 2 through the linear reciprocating drive mechanism 11, and the cigarette beating motor 8 is started at the same time, and the cigarette beating motor 8 drives the circular cutter 10 to rotate at high speed When the adsorption box 3 passes through the circular cutter 10, the bottom of the tobacco layer is cut flat, ensuring that the tobacco adsorbed and extracted each time has the same thickness and weight and meets the required weight. When the adsorption box 3 reaches above the weighing tray 2, the negative pressure suction device is closed to make the tobacco fall onto the weighing tray 2. The weighing tray 2 transfers the tobacco to the next process and pours it out. Then, the weighing tray 2, the linear module 11 and the adsorption box 3 are reset, and the above operation is repeated. Then, the weighing tray 2 can receive the same weight of tobacco again. The efficiency of extracting tobacco is high, the weight accuracy of extracted tobacco is high, the filling efficiency is improved, the degree of mechanization is high, the labor intensity is low, the labor cost is low, tobacco pollution is avoided, and the test results are guaranteed.

[0034] After working for a period of time, in order to ensure the adsorption effect, the negative pressure suction device is controlled to blow air in the reverse direction to clean the adsorption mesh plate 4 of the adsorption component to achieve self-cleaning.

The slide cylinder 13 can accurately control the height of the adsorption box 3.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
