Description
Technical field
The utility model relates to a kind of detecting device, especially relates to a kind of pick-up unit that the can crimping repeatedly connects rate that detects.
Background technology
Can is to pack in the container processing raw-food material after the seasoning, through making behind the sealing high temperature sterilization, has long shelf-life, transport easy to carryly, edible easy, and is not subjected to season and the regional advantages such as restriction, liked by the consumer.It is not corrupt why tinned food can keep for a long time, be because container by vacuum seal after, food in the tank has completely cut off and the contacting of air, extraneous microorganism can't invade tank internal contamination food, so the airtight quality of crimping is extremely important, be to guarantee the long-time most important condition of preserving of food.The can pack container generally adopts tinplate to make, the hermetically-sealed construction of can all is the double seam formula, namely be to intervolve mutually between can body and the cover, pair of rollers can body by tin seamer is repeatedly done relative lift-over with the cover trip edge, make the edge of the two because of flexural deformation, closely hook together mutually and reach sealing (such as Fig. 1).To the can of outlet American-European countries, U.S. FDA is very strict to the airtight quality requirement of container crimping 3, and the crimping 3 that proposes can must reach three 50%, and namely repeatedly spreading degree and the rate that repeatedly connects all must be greater than 50%, and wrinkle rating is less than 50%.Shown in Fig. 2,3, the body hook 11 of crimping can body 1 hooks together together with the lid hook 21 of cover 2, body hook 11 is greater than more than 50% of crimping 3 width with the length that lid hook 21 overlaps, repeatedly connect rate and be body hook and the actual repeatedly spreading degree of lid hook divided by the body hook with cover the hook theory spreading degree that changes and multiply by 100 and draw.Lid hook and hooking together of body hook are to be formed overlapping by the extruding of roller groove, the standard radian that roller groove and cover round edge two cooperatively interact, and the correct debugging of tin seamer, be directly connected to the quality of tank body sealing crimping, at tin seamer at a high speed and in the process of long-term operation, die wear occurs easily and affect the airtight quality of crimping, so the manufacturing enterprise that can exports, in process of production, a timing can opening of overlapping three grades has been set up in the detection of crimping and detected system.Repeatedly connect the detection of rate for crimping, because there not being checkout equipment, checker and tin seamer commissioning staff detect the rate that repeatedly connects of crimping, all are the measurement data according to body, lid hook width and seam width, by the computing formula that repeatedly connects rate: repeatedly meet rate %=(BH+CH+1.1tc-W)/(W-(2.6tc+1.1tb)) * 100 and calculate, such as Fig. 3, in the formula: BH is body hook width, and CH is for to cover the hook width, and W is seam width, tc is bottom iron thickness, and tb is can body iron thickness.This detection method speed is very slow, has affected production efficiency, in case go wrong in the production run, because detection speed is slow, can not in time find, produces easily a large amount of substandard products, causes serious economic loss.
Summary of the invention
The purpose of this utility model is for existing problem, provides a kind of speed fast, and precision is high, and volume is little, and is easy to carry, and can crimping simple to operate repeatedly connects the rate pick-up unit.
In order to solve above-mentioned technical matters, the technical scheme that adopts is: a kind of crimping repeatedly connects the rate pick-up unit, comprise housing and be arranged on the interior digital display system of this housing, the inner chamber of described housing is provided with dip stick, the fixed claw of dip stick is parallel to each other corresponding with mobile moving jaws on dip stick, and stretch out outside the housing their lower end, dip stick and moving jaws two forward surfaces are equipped with the palisade pole piece of sensor, moving jaws one side connects one and promotes the moving jaws displacement and with the push rod of teeth, the teeth of push rod and gear engagement, the top of housing is provided with body hook numerical value input key and lid hook numerical value input key and crimping numerical value input key, also be provided with on the panel of housing to read and repeatedly connect rate score affirmation button, each button links to each other single-chip microcomputer with the single-chip microcomputer of digital display system, sensor, control circuit and display screen are electrical connection.
Also be provided with on ﹠ off switch, zero suppression key, shift key on the panel of described housing.
The gear shaft of described gear is fixed on the housing, and gear bush has torque spring, and torque spring places in the gear, and the torque spring two ends are fixed on gear and the gear shaft.
The top of described push rod is provided with the promotion key, promotes key and stretches out outside the housing.
Two of described dip stick and moving jaws are provided with between the forward surface of palisade pole piece and are provided with the gap.
Described housing inner chamber also is provided with the battery compartment that power supply is provided.
After adopting above-mentioned structure, when the measurement crimping moves moving jaws, be fixed in opposite directions that relative displacement produces between the palisade pole piece of the capacitor grid transducer on dip stick and the moving jaws, this displacement is transformed into the phase changing capacity of electric signal, gives metering circuit and carry out data and process and convert digital quantity to and show from display screen; Body hook numerical value input key is used for the numerical value of input body hook width measure; Lid hook numerical value input key is used for the numerical value that the hook width measure is covered in input; Crimping numerical value input key is used for the numerical value that the input seam width is measured, by each button the data of measuring are input in the single-chip microcomputer, deposited the rate that repeatedly the connects computing formula program of input in the storer of single-chip microcomputer, control circuit is confirmed the push button signalling indication by repeatedly connecing rate score, digital quantity signal after the computing is input on the display screen again shows, we just can intuitively read the rate that repeatedly connects of crimping.When operation, press the promotion key of moving jaws, make moving jaws and fixed claw displacement and clamp crimping, there is this moment relative displacement to produce between moving jaws and the dip stick, this displacement is converted to digital quantity, and show at display screen, press crimping numerical value input key, with measured to the seam width value be input in the single-chip microcomputer; Same method, measure lid hook width and body hook width after the tank body crimping is disassembled, in succession press body hook numerical value input key and lid hook numerical value input key, the numerical value that covers hook width and body hook width is input in the single-chip microcomputer, press again and repeatedly connect rate score affirmation button, control circuit is indicated by push button signalling, shows the rate that repeatedly the connects result that screen display calculates.
The utility model has improved the detection speed that repeatedly connects rate, and computational accuracy is high, and simple to operate, volume is little, and is easy to carry.
