Wheel 26.
Adhesive tape 24 rotates a circle and parcel realizes circumference packaging, and centre experiences Automatic-clamping, smooths the mistake with automatic shearing
Journey, in order to realize these steps, designed gear ring 25 and cam assembly 3 to complete these motion, by with train wheel bridge,
The combination of lower platen 13 completes whole packaging.
Refer to Fig. 5-Fig. 8, cam assembly 3, by cam A31, cam B32, cam C33, cam D34, cam E35,
Cam F42, pressing plate B, shearing blade 38, chuck 39 form with pressing plate A, cam A31, cam B32, cam C33, cam D34, cam

Pressing plate about the B place 37 connection cam F42 of place 36 connection cam E35, pressing plate bar B.
2, concrete Packaging Principle:
Stage one: wrap up by being manually placed on lower platen 13 appointment position, adhesive tape 24 one end is placed in cam assembly 3, profit
Clamping with chuck, start power supply, lifting assembly 6 promotes lower platen 13 to be promoted by parcel, and parcel touches bottom train wheel bridge
Lift assembly 6 after travel switch to quit work, wrap up Automatic-clamping.
Stage two: pressing plate A locates 40(up and down and connects cam A31) move downward to be pressed in adhesive tape 24 and wrap up surface, pressing plate A is left
Right place 41(connects cam D34) continue to move right an adhesive tape 24 head part and smooth and to encapsulate parcel surface, whole cam fills
Part 3 is return.
In the stage three: gear 26 and gear ring 25 engage, adhesive tape 24 is arranged on gear ring 25 surface, and gear ring 25 rotarily drives adhesive tape 24
Rotating, rotate a circle, parcel realizes circumference packaging, adhesive tape 24 returns to the position started when packing.
In the stage four: the cam assembly 3 originally exited moves again, chuck 39(connects cam C33) transport downwards
Dynamic clamping adhesive tape 24, then shearing blade 38(connects cam B32) move downward and cut off adhesive tape 24, then pressing plate bar B locates 36 up and down
(connecting cam E35) moves downward and adhesive tape 24 is pressed in parcel surface, and last pressing plate about B place 37(connects cam F42) to the left
Motion smooths on parcel surface.
After whole packaging completes, adhesive tape end is clamped by chuck, eliminates the puzzlement again looking for adhesive tape end, second time bag
Directly parcel is put into the when of dress lower platen 13, starts power supply the most permissible.
3, innovative point and application
1) type of parcel is not limited by automatic packaging machine, can not only pack casing class parcel, it is also possible to pack packed bag
Wrap up in, as books, clothes etc. wrap up;
2) packer is small and exquisite, overall floor space, convenient placement;
3) packer weight also only has about 40kg, is moved easily;
4) packer is with low cost, and according to investigation, the most can not pack the machine of multiclass parcel;
5) simple to operation, it is suitable for businessman of middle-size and small-size Taobao or the businessman of Taobao of ground zero and express company, eliminates fast
The packing charges that company of passing is unnecessary;
6) within packer completes once to wrap up and is packaged in 10s, the most rapidly, a large amount of saving packaging times.
Application prospect
Along with the development of present shopping at network, the quantity of parcel is also ramping every day, and how fast package has been rolled into existing
In problem in the urgent need to address, it is contemplated that to how fast package wraps up this problem, further according to the investigation in market and
Analyzing, so devising this general-purpose glue banding packing machine, being possible not only to pack casing class parcel, it is also possible to packaging bag turns class
Parcel, and product overall volume of the present invention is little, only has about 1/3 size of normal packet installation on the market, takes up an area less than one cube
Rice, weight only has about about 40kg, it is simple to mobile and placement.Installing compared to the normal packet on market, the present invention is not only suitable for
High-volume packaging, also is adapted for the packed single of businessman of small-sized Taobao, uses with the opening, and it is convenient to facilitate.So relative to current packer
Market, packer of the present invention has the advantage of oneself uniqueness, and application prospect is the most optimistic.
4, Design Theory calculates:
4.1 overall framework size design
After the parcel Package size determined is 420X300X300mm to the maximum, the interior diameter of design gear ring is 560mm, with sheave pair
Gear ring carries out clamping to be fixed, it is thus determined that a length of 800mm of the general frame of mechanism, a height of 800mm, a width of 860mm
The design of 4.2 lifting assemblies 6 and lifting assembly 6 selection of Motor
Lower platen 13 undertakes the intensity (stress of lifting assembly 6) of goods
By above analyzing investigation, product of the present invention packaging size is 420*300*300 to the maximum, and package weight is less than or equal to 20kg,
Then F=198N, g=9.8N*M
According to the needs of the clamping parcel that lower platen 13 moves up and down, devise the lifting assembly 6 supporting lower platen 13 motion,
Structure chart is as shown in Figure 2.
According to parcel specification, lifting assembly 6 stroke of design at H=0-300mm,
Being elevated to maximum position required time is T=1.5s
Lifting assembly 6 maximum weighted is i.e. size F=198 of lower platen 13 load-bearing
Then the acting of lifting assembly 6 is;W==594J
Analysis to lifting assembly 6 working environment, looks into mechanical design handbook 17, selects 12V direct current generator to transmit lifting
The power of machine
The power of lifting assembly 6
P=39.6/1.5=39.6W
Assume motor efficiency of transmission N=90%
Then motor temporal power P(is actual)=P/90%=44W
The most finally select the motor of 12v 45W.
4.3 industrial aluminum profile stress deformation amounts calculate
M aluminium section bar line density (kg)
L load (N)
L aluminium section bar unbraced length (mm)
E elastic modelling quantity (70000)
I set inertia ()
Z cross section inertia ()
g=9.81N/kg
Deflection (mm)
Aluminium section bar deflection under dead load situation:
Aluminium section bar deflection under no load state:
The maximum allowable bending stress of aluminium section bar:
4.4 cam assembly 3 designs calculate
4.4.1 according to the size of general frame, devising the size of cam platform, the whole height of cam platform is 300mm.Root again
The function completed by regular hour order according to cutter, chuck and pressing plate, uses the mechanism of cam to complete each motion.Due to
The height of cam and chuck, cutter, the height of pressing plate and the relation of stroke distribution, utilize lever principle, devise the connecting rod of 1:2
Reduce Leahy and overall size.And because in packaging process, in order to allow the motion of cam platform and gear ring not interfere,
Cam platform needs to exit a certain distance, therefore uses spring sliding track mechanism to realize the advance and retreat of cam platform.Integrated model such as figure
Shown in 5-7.
4.4.2 the determination of base radius
When designing cam, in addition to considering that cam assembly 3 has preferable stressing conditions, in addition it is also necessary to have compact chi
Very little, for making the mechanism can work well, it is stipulated that the allowable value of pressure angle, on the premise of allowable value allows, choose the least
Base radius.
According to formula
Choose the eccentric throw of the pressure angle beneficially reducing rise, the base radius of minimum can be obtained,
=125mm
Checking through actual motion, cam base circle meets movement needs
4.4.3 the determination of cam contour
The time that the function completed by regular hour order according to cutter, chuck and pressing plate and cam are retreated designs cam
Profile, as design time distribute the angle corresponding to each cam contour, further according to the row of cutter, chuck and pressing plate
Journey designs the stroke of cam, analyzes as shown in table 2.
