Description
Technical field
The utility model relates to a kind of Packing Machines, more specifically to a kind of positive/negative-pressure Packing Machine.
Background technique
Packing Machine is called thermoplastic shaping machine, is by the thermoplastics coiled material such as PVC, PE, PP, PET, HIPS of heating plasticizing
Inhale the machine that the products such as advanced packing and decorating box of various shapes, frame are made.The pull of vacuum generated using vacuum pump, will heat
The thermoplastic plastics sheet material such as PVC, PET after softening is by mold plastic uptake at vacuum (-tight) housing of various shapes, plastic-sucking tray, blister
Deng.
Packing Machine is generally divided into negative pressure Packing Machine and positive/negative-pressure Packing Machine, and difference is that negative pressure Packing Machine only has plastic uptake function
Can, positive/negative-pressure Packing Machine has the function of blow molding and plastic uptake；Negative pressure Packing Machine is lower than positive/negative-pressure Packing Machine cost, and structure is more
It is simple.
Positive/negative-pressure Packing Machine generally includes grasping system (i.e. sheet conveying mechanism), heating system, vacuum and compressed air
Several parts such as system, shaping mechanism, shaping mechanism include upper mold, lower mold, and upper mold bottom surface is equipped with forming cavity, sheet material at
The intracavitary molding of type, vacuum and compressed air system are connected to lower mold.Usually there are one and vacuum and compressed air on lower mold
The stomata of system connectivity is used to plastic uptake (vacuumizing) or blow molding (air blowing).
But the shortcomings that above-mentioned this scheme, is, and due to being evacuated or blowing by a biggish stomata of internal diameter, each portion
The air-flow divided is not uniform enough, it is difficult to ensure steady air current, so if being used to smaller and right in equal volume to nicknack vehicle shell

Hole, it is better quality, more stable so that more evenly, the power for allowing sheet material to be subject to is more uniform for the flowing of gas when vacuumizing, blowing.
And heating system is connect with lower mold, is directly heated to lower mold, can be saved a step, be not only saved space, and
It improves work efficiency, in process, the air (hot-air) of lower die top and the blowout of micro- stomata can be persistently equal
Sheet material is heated evenly, further improves product quality.
Preferably scheme, the lower mold bottom surface are equipped with the air cavity that shape is in inverted cone body shape, and air cavity bottom end opening is logical
Tracheae is crossed to be connected to vacuum and compressed air system.That is, air cavity top internal diameter is greater than air cavity bottom end internal diameter, this design
The stability of the gas flowing by each micro- stomata can further be improved.
Preferably scheme, the inside diameter ranges of micro- stomata are 0.20-0.50 millimeters.Preferred scheme, micro- stomata
Inside diameter ranges be 0.30-0.40 millimeters.Internal diameter is too small, and it is too fast to will lead to air-flow, causes adverse effect to molding, and be difficult to
Processing；And internal diameter is excessive, then the effect being not achieved.
Preferably scheme, the lower die top have shaping area, and the lower die top in shaping area is covered with micro- gas
Hole.
More optimal solution, the lower die top square centimeter in shaping area have 2-8 micro- stomatas.Preferred side
Case, the lower die top square centimeter in shaping area have 4-6 micro- stomatas.
Preferably scheme, the heating system include heating device and Duo Gen heating tube, and heating device adds with more respectively
Heat pipe electrical connection, lower mold are provided with heating tube slot, and heating tube is inserted into heating tube slot.
More optimal solution, the temperature range of the heating tube are 80-100 degree.
Compared with the prior art, the utility model has the beneficial effect that due to being improved existing structure, by gross blow hole
It is changed to micro- stomata, therefore air flowing is more evenly stable；And heating system is directly connected to lower mold, then can reduce processing step
Suddenly, working efficiency is improved, makes sheet material heated more evenly, the quality for processing shell is very good and stable, can satisfy people
Demand to high-quality product.
