Description

Technical Field

[0001] This utility model relates to the field of tobacco and tobacco product grinding technology, and in particular to a sample preparation device for tobacco and tobacco product laboratory use. Background Technology

[0002] In the analysis and testing of tobacco and tobacco products, it is necessary to prepare solid tobacco powder samples, which generally involves grinding, pulverizing, and sieving, often using small pulverizers. Existing pulverizing equipment is prone to accidental activation of switches when placing or discharging samples after pulverization, causing mechanical damage. Frequent plugging and unplugging of the power supply can also easily generate sparks. Utility Model Content

[0003] This invention primarily addresses the technical problem of accidental mechanical injury caused by accidental contact in existing laboratory sample preparation devices. It proposes a laboratory sample preparation device for tobacco and tobacco products, equipped with a safety interlock device for protection, which can reduce the risk of mechanical injury from accidental contact. Simultaneously, the pulverizer body can rotate, facilitating sample pouring and filtering, thus combining ease of use with enhanced safety.

[0004] This utility model provides a laboratory sample preparation device for tobacco and tobacco products, including a base;

[0005] Protective plates are provided on both sides of the base; the crusher body is located between the two protective plates; a top cover is provided on the top of the crusher body;

[0006] A sample tray is movably arranged between the base and the crusher body.

[0007] Furthermore, the two sides of the crusher body are respectively mounted on the protective plate by fastening bolts;

[0008] When the fastening bolts are tightened, the crusher body is fixed to the protective plate;

[0009] When the fastening bolt is loosened, the crusher body can rotate around the fastening bolt.

[0010] Furthermore, the top cover is connected to the crusher body via a snap-fit ​​mechanism.

[0011] Furthermore, a safety interlocking device is provided on the buckle.

[0012] Furthermore, a sieve is provided between the sample tray and the pulverizer body.

[0013] Furthermore, a vibrator is provided on the outer wall of the screen.

[0014] Furthermore, a vibration switch and a crushing switch are respectively installed on the side of the protective plate on the right side of the base;

[0015] The crushing switch is electrically connected to the safety interlock device; the vibration switch is electrically connected to the vibrator.

[0016] Furthermore, the screen has a variety of particle sizes.

[0017] Furthermore, a ring-shaped buckle is provided on the lower inner side of the protective plate.

[0018] Compared with the prior art, the sample preparation device for tobacco and tobacco products in the laboratory provided by this utility model has the following advantages:

[0019] 1. The preparation device of this utility model is equipped with a buckle, and a safety interlock device is installed on the buckle. The safety interlock device is electrically connected to the pulverizer switch. When the top cover is open, the pulverizer cannot be started. When the top cover is opened during operation, the pulverizer blades stop directly, reducing mechanical damage caused by accidental contact and ensuring high safety.

[0020] 2. The pulverizer body of this utility model preparation device can rotate. After the pulverization work is completed, the fastening bolts can be loosened directly, and the pulverizer can be rotated manually so that the opening of the pulverizer body corresponds to the sample tray, and the sample can be taken out directly. The operation is simple and the work efficiency is increased. Attached Figure Description

[0024] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0025] like Figure 1-2 As shown in the figure, a sample preparation device for tobacco and tobacco products in the laboratory provided by this utility model includes a base 10;

[0026] Protective plates 9 are respectively provided on both sides of the base 10; the crusher body is located between the two protective plates 9; a top cover 8 is provided on the top of the crusher body; the top cover 8 is connected to the crusher body by a buckle 1, and a safety interlock device is provided on the buckle 1. The safety interlock device is an electrical safety interlock device. The buckle has a safety interlock device. When the top cover is closed, it will contact the contact of the safety interlock device. The crusher will only start working when the crushing switch is opened. This is how the safety interlock is achieved, which is similar to the principle that a washing machine will not work when the lid is open.

[0027] A sample tray 4 is movably disposed between the base 10 and the pulverizer body. Multiple annular clips are arranged along the vertical direction on the lower inner side of the protective plate 9; the annular clips on the two protective plates are symmetrically arranged, and the two ends of the sample tray can be locked onto the annular clips. When the sample tray needs to be removed, it can be lifted upwards. A sieve 3 is disposed between the sample tray 4 and the pulverizer body. After the sample tray is placed, the two ends of the sieve are also locked onto the annular clips. A vibrator 7 is disposed on the outer wall of the sieve 3. A sieve cover is fitted on the top of the sieve 3 to prevent sample splashing when the vibrator is working. The sieve 3 has multiple particle sizes, suitable for screening samples of different diameters. A sieve cover is fitted on the upper end of the sieve 3; after the pulverized sample is introduced into the sieve 3 from the pulverizer body, the sieve cover is closed.

[0028] The pulverizer body is mounted on the protective plate 9 on both sides by fastening bolts 2; the pulverizer body has symmetrical vertical grooves on both sides, and the fastening bolts 2 can be tightened into the vertical grooves.

[0029] When the fastening bolt 2 is tightened, the crusher body is fixed on the protective plate 9;

[0030] When the fastening bolt 2 is loosened, the crusher body can rotate or move up and down around the fastening bolt.

[0031] Vibration switch 6 and crushing switch 5 are respectively installed on the protective plate 9 on the right side of the base 10; the crushing switch 5 is electrically connected to the safety interlock device; the vibration switch 6 is electrically connected to the vibrator 7.

[0032] The working process of this utility model patent is as follows: Open the top cover 8, place the sample to be crushed into the crusher body, connect the power supply, close the top cover 8, tighten the buckle, and turn on the crushing switch 5. At this time, the safety interlock device senses the buckle being tightened, and the crusher starts working. After crushing, turn off the crushing switch, open the top cover, loosen the fastening bolt 2, rotate the crusher body so that the crusher body opening aligns with the sieve 3, pour the crushed sample into the sieve 3, then close the sieve cover, turn on the vibration switch 6, and the vibrator 7 starts working. The vibration uses vibration to sieve the crushed sample into the sample tray 4. After sieving is complete, remove the sample tray 4 and bag the sample. Figure 2 As shown.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
