Problems solved by technology

Due to the thickness and elasticity of the double-sided adhesive, and the error of manual bonding is also large, which will affect the measurement accuracy
For example, when testing the pressure application time, manual observation and stopwatch are often used in conjunction with the measurement method, which will also affect the measurement accuracy
For example, when measuring displacement when applying pressure, manual observation and calipers are often used in conjunction with measurement methods, which will also affect the measurement accuracy
[0006] However, the existing hardness testing equipment has methods such as up and down pressure testing and left and right pressure testing, and there is no unified matching verification device, which not only affects the measurement accuracy, but also is not conducive to the general technology promotion of hardness testing equipment

Embodiment 1

[0031] Such as Figure 1 to Figure 2 As shown, a comprehensive test bench hardness unit rapid verification device of this embodiment includes a clamping base 1 and a column 2 vertically arranged on the clamping base. The column 2 is provided with a bracket 3 vertically arranged thereon. The bracket 3 The end of the sensor is provided with a verification sensor mounting seat. The verification sensor mounting base includes a base body and a sensor installed on the base body, and the central control display 8 of the sensor is installed at the clamping base 1 .

[0032] In this embodiment, the sensor is a load cell 73, so that pressure verification can be realized.

[0033] The seat body includes a support arm 71 extending forward along the direction of the bracket 3, the end of the support arm 71 is provided with a seat ring 72, the load cell 73 is embedded on the seat ring 72, and the sensing surface of the load cell 73 protrudes from the seat ring 72 setting, which is conveni...

Embodiment 2

[0042] like Figure 3 to Figure 4 As shown, the difference between this embodiment and the first embodiment is that the sensor is a grating scale sensor 62, and the grating scale sensor 62 is installed on the base body 61, so that the pressure displacement can be verified.

[0043] The sensor can also be an infrared sensor or an image sensor, and its installation refers to the second embodiment, which can cooperate to realize the verification of the pressure application time or pressure displacement.

Abstract

The invention discloses a quick verification device for a hardness unit of a comprehensive testing platform, which comprises a clamping base and a column vertically arranged on the clamping base. There is an angle adjustment mechanism between the verification sensor mounting seat and the bracket, and a level and lifting adjustment mechanism between the bracket and the column. The invention not only realizes the horizontal and lifting support adjustment of the verification sensor mounting seat, but also realizes the rotation adjustment of the verification sensor mounting seat, so that it can be applied to the cooperative verification of different hardness detection equipment, not only ensuring the accuracy of measurement, but also It is beneficial to general technical promotion of hardness testing equipment.

Description

technical field [0001] The invention belongs to the technical field of comprehensive testing of cigarette filter rods, and in particular relates to a rapid verification device for hardness units of a comprehensive test bench. Background technique [0002] Cigarette hardness refers to "the percentage of the diameter of the sample after being subjected to a certain radial pressure in a certain period of time and the diameter of the sample before being compressed." The hardness of cigarettes and filter rods is one of the physical indicators required by the national standard. Hardness It is an important technical index to comprehensively evaluate the processing performance and quality of cigarettes and filter rods. It is closely related to the weight and draw resistance of cigarettes and filter rods. It directly affects the quality and efficiency of cigarette and filter rods. , smoke analysis, tar content, carbon monoxide, nicotine content and other chemical indicators have a ce...
