Hauv kev lag luam ntawm cov khoom ntim tsis siv neeg, lub khob khob tshuab tau dhau los ua cov cuab yeej tseem ceeb ntawm kev lag luam ntim khoom noj niaj hnub vim tias nws muaj peev xwm ua tau zoo thiab raug. Cam mechanism, raws li cov tub ntxhais kis tau tus mob ntawm daim ntawv khob tshuab, paub qhov tsis siv neeg txuas ntawm ntau tshaj kaum txheej txheem xws li ntawv suction, yas shaping, sealing thiab curling nyob rau hauv daim ntawv khob ntau lawm los ntawm meej mechanical zog tswj. Nyob rau hauv daim ntawv no, lub hauv paus ntsiab lus ntawm kev ua hauj lwm, cov yam ntxwv ntawm tus yam ntxwv thiab cov tswv yim siv ntawm no mechanical kis tau tus mob yuav qhia nyob rau hauv ib qho yooj yim -to- to taub.
I. Cam Mechanism: "conductor" ntawm Mechanical Motion
Cam mechanism yog ib tug khub siab mechanism uas tus tsav taug qab (xws li laub pas nrig lossis viav vias pas nrig) paub txog qee txoj cai txav los ntawm qhov nkhaus ntawm tus tswv cuab tsav (cam). Nws tus nqi tseem ceeb nyob rau hauv lub peev xwm los hloov cov kev sib hloov mus rau hauv txoj kab ncaj nraim los yog oscillating motion, nrog kev tswj kom meej yam tsis tas yuav tsum muaj txoj hlua sib txuas sib txuas.
1.1 Peb lub ntsiab lus tseem ceeb ntawm cov qauv
- Cam: Ib qho kev txav, feem ntau yog disc -zoo li tus, cylindrical, lossis muaj ib qho profile tshwj xeeb. Nyob rau hauv cov ntawv khob tshuab, disk cams feem ntau yog siv los tsav cov kev sib hloov ua raws.
- Hauv qab: Tus actuator tuaj yeem muab faib ua ob hom, linear (nce thiab nqis) thiab oscillatory (rotating nyob ib ncig ntawm lub axis ruaj), raws li nws hom kev txav. Cov menyuam ua raws li feem ntau rau cov ntawv khob tshuab, txo kev sib txhuam los ntawm kev sib cuag.
- Ncej: tus neeg txhawb nqa uas kho lub camshaft thiab txwv txoj kev txav ntawm tus neeg taug qab kom ntseeg tau qhov kev ruaj ntseg ntawm lub cev.
1.2 Cov ntsiab cai hloov pauv hloov.
Thaum lub cam tig ntawm qhov ceev tsis tu ncua, qhov chaw sib cuag ntawm qhov chaw ntawm lub cam thiab cov neeg taug qab hloov tas li, yuam cov neeg taug qab mus raws li qhov kev sib tw ua ntej. Piv txwv li:
- Ascending theem: Lub cam contour radius nce zuj zus, thawb tus neeg taug qab mus rau pem hauv ntej (raws li nyob rau hauv cov txheej txheem sidewall folding txheej txheem thaum daim ntawv khob shaping).
- Lub cam contour vojvoog tseem zoo ib yam thiab cov follower tseem zoo ib yam (xws li thaum cua sov thiab sealing thaum compression).
- Rov qab theem: Cam contour radius txo thiab rov qab mus rau qhov qub (npaj rau lub voj voog tom ntej).
- Lub sij hawm no "thawb-dwell-rov qab" cov lus tsa suab yog tus yuam sij rau kev tsim cov ntawv khob tas li.
Daim ntawv thov kev tshuaj ntsuam ntawm Cam Mechanisms hauv Paper Cup Tshuab
Siv yim lub khob ntim puv tshuab, uas nws cov txheej txheem tseem ceeb suav nrog:

Cam system configuration:
- Main cam: Tswj lub nce thiab nqis txav ntawm molding tuag.
- Pab cam: Tsav cov kab rov tav txav ntawm sab phab ntsa folding phaj.
- Indexing cam: Siv qhov chaw nres tsheb hloov dua siab tshiab (8-station intermittent rotation).
Lub sijhawm ua haujlwm:
- 0℃-45 degree: Cov tuag nce thiab cov phaj folding txuas rau kab rov tav.
- 45℃-135℃: Cov tuag txuas ntxiv nce thiab cov phaj folding ua tiav rau sab pre-folding.
- 135℃-225 degree: Cov tuag txuas ntxiv nce thiab cov phaj folding ua tiav qhov kawg folding.
- 225℃-315 degree: Pwm txo, folding phaj shrinks.
- 315℃-360 degree: Cov pwm tseem poob qis, npaj rau lub voj voog tom ntej.
Technological breakthroughs:
