Tank bottom pressure-resistant detection device with tank slip detection function

Abstract

The invention discloses a tank bottom pressure-resistant detection device with a tank slip detection function, and belongs to the field of package detection. The pressure-resistant detection device comprises a mounting frame, and also comprises a clamping assembly, a pressurization assembly, a deformation measurement assembly and a tank slip detection assembly, wherein the clamping assembly, the pressurization assembly, the deformation measurement assembly and the tank slip detection assembly are arranged on the mounting frame; the clamping assembly is used for clamping a tank body; the pressurization assembly is used for sealing in the tank body to form a pressurization cavity and pressurizing the pressurization cavity; the deformation measurement assembly is used for detecting the deformation amount of the bottom of the tank body; the tank slip detection assembly comprises a spring, a gratin ruler base, an auxiliary detection part and a grating ruler reading head; the auxiliary detection part is abutted against the tank opening of the tank body; the grating ruler reading head is arranged on the grating ruler base in a sliding manner; a moving assembly is connected with the mounting frame through the spring; one end of the spring is connected with the mounting bracket, and the other end of the spring is connected with the moving assembly; and when the spring slides on the tankbody, the auxiliary detection part is driven to move up along with the tank opening, and the grating ruler reading head reads the reading of the upward displacement. By virtue of the tank bottom pressure-resistant detection device, the accuracy of the tank bottom pressure-resistant detection value can be improved.

Description

technical field [0001] The invention relates to the field of packaging testing instruments, in particular to a tank slip detection mechanism and a pressure-resistant detection device with a calibration function. Background technique [0002] At present, pop cans are widely used in beer, beverage and other industries due to their environmental protection and aesthetic advantages. Changes in the external air temperature can also easily lead to an increase in the internal pressure of the tank; at the same time, in order to reduce costs, the factory generally thins the thickness of aluminum (or other tank materials) when making tanks, thereby reducing the pressure resistance of the tank bottom. Strength affects; in order to ensure that the cans maintain good pressure resistance during the process of packaging, transportation, and sales, and to avoid bulging or cracking of the cans, canning companies generally need to check the bottom of the cans (or called the bottom arch, that ...

Problems solved by technology

[0005] Due to the thin wall of the can, in order to avoid clamping and deforming the can body, the clamp cannot exert excessive clamping force on the can body. When the air pressure in the pressurized chamber increases, the can body will have a relative clamp The trend of sliding upwards, and in the specific detection process, it is impossible to guarantee whether the tank body is sliding upwards, so the accuracy of detecting the deformation of the tank bottom cannot be guaranteed
