But prior art there is problems：1st, only carton interior dust suction is not disappeared to carton interior Poison is very unhygienic；2nd, prior art continuously can not carry out dust suction or sterilization to carton, very inconvenient.

The content of the invention

It is an object of the invention to provide carton sterilization method, dust suction and sterilization continuously can be carried out to carton.

To reach above-mentioned purpose, base case of the invention is as follows：

Carton sterilization method, it is characterised in that carried out disinfection using carton continuous sterilization equipment, carton continuous sterilization equipment Including conveyer belt, conveyer belt includes transmission plane, driving wheel and driven pulley；Transmission plane is driven by driving wheel and driven pulley；Driving wheel Driven by partial gear；Transmission plane is provided with the cavity for placing carton, and transmission plane top is provided with and is promoted by power set respectively Hairbrush, sterilization dust removal machine and drying unit, hairbrush, sterilization dust removal machine and drying unit along conveyer belt direction of transfer successively Set；Sterilization dust removal machine includes atomization chamber, gas blow pipe and suction muffler；Atomization chamber is connected with gas blow pipe, the outlet side position of gas blow pipe In the lower section of sterilization dust removal machine；Top in atomization chamber is provided with airduct, and the bottom of atomization chamber is provided with disinfectant tube and multiple tuning forks, The bottom surface of atomization chamber is provided with apocenosis passage, and apocenosis passage is connected with discharging tube, and the drain side of discharging tube is provided with recovery pond, thimerosal Pipe is connected with recovery pond, and disinfectant tube is provided with water pump；Suction muffler is provided with air intake duct, and the suction port of air intake duct is located at sterilization The lower surface of dust removal machine.

Carton sterilization method is as follows：

Step one, places carton：By carton place on a moving belt and carton bottom be located at cavity in, conveyer belt is not The time that complete gear is engaged with driving wheel is the working time, otherwise is then the intermittent time；Intermittent time is 30~80s；

Step 2, rub carton：Carton in step one moves to hairbrush lower section, and hairbrush is moved downward and the carton that rubs Wall；The number of times of hairbrush friction carton walls is 2~4 times；

Step 3, dedusting of sterilizing：Carton in step 2 moves to sterilization dust removal machine lower section, and sterilization dust removal machine is moved downward Carry out disinfection dedusting to carton；The time of sterilization dedusting is 30~60s；The internal diameter of disinfectant tube is 0.5~1cm, disinfectant tube Spray speed be 1m/s；The wind speed of airduct is 1m/s；

Step 4, drying：Carton in step 3 moves to drying unit lower section, and drying unit moves downward and carton is entered Row drying；The time of drying is 10~15s.

When using, carton is placed on transmission plane, conveyer belt, when now carton moves to hairbrush lower section, Conveyer belt stop motion, power set promote hairbrush to move down, and now hairbrush can rub four walls of carton so that the four of carton Wall friction is negatively charged, and hairbrush is withdrawn in motion to power set upwards；Conveyer belt is rotated again, is removed when this carton moves to sterilization When dirt machine lower section, conveyer belt stop motion, power set promote sterilization dust removal machine to move downward, until sterilization dust removal machine Bottom is parallel with carton mouthful, and now gas blow pipe is extend into carton, positively charged atomization disinfection liquid (i.e. droplet charge cloud) Can be injected into carton, and carton walls are negatively charged, positively charged atomization disinfection liquid can be adsorbed on the wall of carton four.Separately Outward, because gas blow pipe has certain blowing force, the bottom of carton can be directed onto the thimerosal after being atomized so without worrying carton bottom Portion can be because no electric charge with thimerosal without contacting；After the completion of carton sterilization, power set again receive sterilization dust removal machine Return, now conveyer belt is moved again, when carton moves to drying unit lower section, conveyer belt stop motion, power set Drying unit is promoted to move downward, drying unit is dried to carton, carton below carries out disinfection drying successively.

The technique effect of this programme：

1st, cavity is set on conveyer belt, is primarily to facilitate placement carton, prevent carton from shifting；

2nd, the time that the partial gear of conveyer belt is engaged with driving wheel be the working time, as conveyer belt when Wait；Otherwise the time that then carton continuous sterilization equipment is operated for intermittent time, i.e. conveyer belt stop motion；Wherein, during interval Between be 30s~80s, i.e., carton continuous sterilization equipment running the time be 30s~80s, to be completed within this time to a paper The friction of case, sterilization dedusting and drying；When the intermittent time 30s is less than, the time mistake of carton continuous sterilization equipment operation It is short, carton is rubbed, dedusting sterilization and drying granary promote, it is impossible to enough carton dedusting is sterilized well；Work as the intermittent time When more than 80s, the overlong time of carton continuous sterilization equipment operation can delay the progress of carton dedusting sterilization；

3rd, the setting of hairbrush, primarily to friction papers chamber interior wall so that carton inwall negative charging tribomaterials lotus；Hairbrush rubs The number of times of carton walls be 2~4 times, when Rubbing number less than 2 this when, to carton friction portion completely, carton walls band can be influenceed Static content；Carton walls static electrification is just caused when friction 4 times completely, when Rubbing number is more than 4 times, friction Number of times can excessively influence the progress that carton dedusting is sterilized, and then cause activity time extension；

4th, the setting of atomization chamber, primarily to enabling that the thimerosal sprayed from disinfectant tube strikes atomization chamber Cavity wall；In order to increase the impulsive force of thimerosal, water pump is provided with disinfectant tube；So that the thimerosal for spraying can impact atomization The cavity wall in chamber, the thimerosal after ejection runs into the cavity wall of atomization chamber, liquid is splashed upwards, realizes that impact is powered, is forming band just The atomization disinfection liquid of electric charge；

5th, disinfectant tube is arranged on the bottom of atomization chamber, and airduct is arranged on the top of atomization chamber, the air outlet and mist of airduct Change passage correspondence；When preventing disinfectant tube to be located at airduct top, some big drops fall atomization chamber bottom surface under, easily quilt The wind of airduct is blown away, or is blown into gas blow pipe, and big drop is entered into carton and easily drenches carton, is highly detrimental to paper The later stage of case uses；

6th, atomization chamber bottom sets multiple tuning forks, and when water slug tuning fork, tuning fork can send out place's sound and dither, As long as a tuning fork sends acoustical vibration, other tuning forks all can dither, dither can by thimerosal vibratory atomizer, So that more and the impact band electric forming droplet charge cloud, i.e., positively charged atomization disinfection liquid of disinfectant liquid atomization.

The preferred scheme 2 that improvement to base case is obtained, carton continuous sterilization equipment is externally provided with tuning fork, it is necessary to increase sound During the vibration frequency of fork, the tuning fork outside carton continuous sterilization equipment is tapped.

Tuning fork is set outside carton continuous sterilization equipment, is easy to people to increase the vibration frequency of tuning fork, sterilized when needing to increase When the atomization quantity of liquid, it is only necessary to tap the tuning fork outside carton continuous sterilization equipment, vibration is passed in the form of ripple by medium Other tuning fork (tuning fork i.e. in atomization chamber) place is arrived, the tuning fork in atomization chamber can be with vibration, due to disappearing in atomization chamber Venom can clash into tuning fork, and tuning fork can also vibrate, and both add up so that the vibration of tuning fork is stronger.

The preferred scheme 3 that improvement to base case is obtained, gas blow pipe includes multiple branch pipes, and the outlet side of branch pipe is located at and disappears The lower section of malicious dust removal machine；Branch pipe includes inner and outer tubes, and inner tube is connected with atomization chamber, and outer tube sleeve is on inner pipe；Outer tube and inner tube It is slidably connected；Outer tube is provided with gas hole.

The preferred scheme 4 that improvement to base case is obtained, the thimerosal in step 3 is quaternary ammonium salt thimerosal, quaternary ammonium salt Content is 200mg/L~400mg/L.

When the content of quaternary ammonium salt is less than 200mg/L, the DeGrain of carton sterilization；When the content of quaternary ammonium salt is more than During 400mg/L, concentration crosses conference so that quaternary ammonium salt content overproof in carton, can influence the sterilization of carton；

In addition, thimerosal be quaternary ammonium salt because the mechanism of action of quaternary ammonium salt thimerosal be mainly cation by electrostatic force, Hydrophobic binding between hydrogen bond force and surfactant molecule and protein molecule etc. is acted on, and adsorbs electronegative bacterial body, is gathered On cell membrane, generating chamber's inhibition effect causes bacterial growth suppressed and dead to collection；Its hydrophobic alkyl can also be with the parent of bacterium simultaneously Water base effect, changes the permeability of film, and lysis then occurs, and destroys eucaryotic cell structure, causes the dissolving and death of cell；Will Quaternary ammonium salt thimerosal is sprayed into atomization chamber, and because quaternary ammonium salt thimerosal carries positive charge, it is more that it clashes into generation with atomization cavity wall Positively charged atomization quaternary ammonium salt thimerosal, after it enters in carton, because carton walls are negatively charged, is atomized quaternary ammonium salt thimerosal Can be attracted by carton walls, and then carton walls are carried out disinfection, it is very useful.

The preferred scheme 5 that improvement to base case is obtained, in step 4 using drying be using blowing by the way of High temperature drying is carried out, and drying temperature is 80~100 DEG C.

By the way of high temperature drying, carton inwall can again be carried out disinfection；When the temperature of wind is less than 80 DEG C, though Carton can so be dried, but not reach the effect sterilized again；When the temperature of wind is more than 100 DEG C, carton is easily allowed to produce Combustion is conigenous, it is very dangerous.
