Description

Technical Field

[0001] This utility model relates to the field of paper testing technology, and in particular to a paper dust content measuring instrument. Background Technology

[0002] Traditional paper dust measuring instruments, such as Figure 3 As shown, the device includes a housing 1, a placement plate 2, and a light 3. By placing paper on the placement plate 2 and then illuminating the paper with the light 3, the dust on the paper can be clearly seen. Then, a dust standard chart is taken out for comparison to determine the dust level on the paper. However, in order to better observe the paper, the placement plate 3 is tilted. As a result, the paper is very easy to slip off the placement plate 2, which makes it inconvenient for the user to observe the paper. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper dust content measuring instrument.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a paper dust content measuring instrument, including a housing and a lighting lamp, wherein a rotating hole is provided on the inclined surface of the housing, a rotating connecting tube is inserted into the rotating hole, one end of the connecting tube is connected to an adsorption element, and the other end of the connecting tube is connected to the housing.

[0005] Preferably, the adsorption element is a placement plate, with a cavity inside the placement plate, the cavity being connected to the connecting pipe, and a set of adsorption holes on one side of the cavity.

[0006] Preferably, an air intake pump is connected to one side of the chassis, and the air intake port of the air intake pump is connected to the chassis.

[0007] Preferably, a motor is connected inside the chassis, and the motor drives the connecting pipe to rotate through a transmission mechanism.

[0015] like Figure 1 As shown, the paper dust content measuring instrument provided by this utility model includes a housing 1 and a lighting lamp 3. A rotating hole is provided on the inclined surface of the housing 1, a bearing is installed in the rotating hole, and a rotating connecting pipe 4 is inserted into the bearing. One end of the connecting pipe 4 is connected to an adsorption element 5, which adsorbs paper. The other end of the connecting pipe 4 is connected to the housing 1.

[0016] like Figure 2 As shown, the adsorption component 5 includes a placement plate, a connecting pipe 4 connected to one side of the placement plate, a cavity 6 provided inside the placement plate, a vent 6.2 provided on one side of the cavity 6, the vent 6.2 connected to the connecting pipe 4, and a set of adsorption holes 6.1 provided on one side of the cavity 6, through which paper is adsorbed.

[0017] An air pump 7 is connected to one side of the housing 1. The air inlet of the air pump 7 is connected to the housing 1. The air pump 7 draws air from the housing 1, and then draws air from the cavity 6, so that the adsorption hole 6.1 can firmly adsorb the paper and prevent the paper from slipping and affecting the observation.

[0018] A motor 8 is connected inside the housing 1 and is mounted on an inclined surface inside the housing 1. The motor 8 drives the connecting pipe 4 to rotate via a transmission mechanism. The transmission mechanism includes a drive wheel 8.1 connected to the main shaft of the motor 8. The drive wheel 8.1 drives the driven wheel 8.3 via a transmission belt 8.2. The driven wheel 8.3 is connected to the connecting pipe 4. In this embodiment, the transmission mechanism adopts a belt and pulley mechanism, that is, the drive wheel 8.1 and the driven wheel 8.3 are pulleys, and the transmission belt 8.2 is a belt. The driven wheel 8.3 is provided with a mounting through hole, and is fixed to the connecting pipe 4 through the mounting through hole. The motor 8 drives the drive wheel 8.1 to rotate, and the drive wheel 8.1 drives the driven wheel 8.3 via the transmission belt 8.2. The driven wheel 8.3 drives the connecting pipe 4 to rotate, thereby driving the placement plate to rotate, so that the paper can rotate during observation, allowing the user to observe the paper more conveniently and comprehensively.

[0019] When the paper is placed on the adsorption element 5, the air pump 7 draws air from the inside of the housing 1, and then draws air from the cavity 6 inside the placement plate, so that the placement plate adsorbs the paper through the adsorption hole 6.1, preventing the paper from slipping when observing the paper. In addition, the motor 8 and the transmission mechanism can drive the placement plate to rotate, and the paper can be firmly adsorbed when rotating, making it convenient for users to observe the paper.
