However, in the actual production process, the length of a roll of pultruded plate is long, and the straightness of the entire roll of pultruded plate cannot be tested at one time, and only the straightness of the roll can be tested in sections
Although the degree of deviation of each detected section is qualified, the above-mentioned straightness evaluation method has the possibility that the pultruded plate is biased to one side and causes excessive bending, resulting in missed inspection of unqualified products and unqualified quality, which increases the defective rate and reduces production. efficiency

Embodiment Construction
[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0042] A method for evaluating the straightness of composite pultruded parts, which obtains the straightness of the pultruded board in the current detection section, and the detection section is the section of the pultruded board in the straightness detection state,
[0043] When the straightness is greater than or equal to the first threshold, the pultruded plate in the detection section returns to the correction device for straightness adjustment, and the value range of the first threshold is 1.5mm / 6m~2.5mm / 6m;
[0044] When the straightness is less than the first threshold and greater than or equal to the second threshold, the pultrusion plate in the detection sect...

The invention relates to a straightness evaluation method for a composite pultrusion part. The method comprises the steps that the straightness of a current detection section is acquired, the detection section is a pultrusion plate section in a straightness detection state, and when the straightness is greater than or equal to a first threshold value, the detection section returns to a deviation rectification device for straightness adjustment; when the straightness is smaller than a first threshold value and larger than or equal to a second threshold value, the detection section continues tobe transported, wherein the second threshold value is smaller than the first threshold value; when the straightness is smaller than the second threshold value, the straightness of the detection section is judged to be qualified, and the pultrusion plate of the detection section is rolled; and the number L of times of continuous transportation after detection is counted, and when the number L of times of continuous transportation is accumulated to be equal to a preset threshold value M of the number of times of continuous transportation and the L sections are adjacent sections, it is judged that the detection sections are bent excessively, and the detection sections are sent to the deviation rectifying device for straightness adjustment. The situation that the pultrusion plate is excessively bent towards one side is effectively avoided, and the percent of pass of workpieces is increased.
Description
technical field [0001] The invention relates to the technical field of pultruded sheet detection, in particular to a method for evaluating the straightness of a composite pultruded piece. Background technique [0002] In the process of straightness detection, the comparison between straightness and threshold is often used to evaluate the degree of straightness deviation of the plate. However, in the actual production process, the length of a roll of pultruded plate is long, and the straightness of the entire roll of pultruded plate cannot be tested at one time, and the straightness test can only be carried out in sections. Although the degree of deviation of each detected section is qualified, the above-mentioned straightness evaluation method has the possibility that the pultruded plate is biased to one side and causes excessive bending, resulting in missed inspection of unqualified products and unqualified quality, which increases the defective rate and reduces production....
