Description

A kind of positive/negative-pressure Packing Machine
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 The higher article of required precision is processed, and quality is difficult to ensure, and unstable quality, is unable to satisfy the need of actual production It wants.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of positive/negative-pressure Packing Machine, this positive/negative-pressure plastic uptake function The power for enough allowing sheet material to be subject to is more uniform, better quality, more stable, effectively improves the precision of processing.The technical solution of use It is as follows:
A kind of positive/negative-pressure Packing Machine, including sheet conveying mechanism, heating system, vacuum and compressed air system, molding machine Structure, shaping mechanism include rack, upper mold, lower mold, upper mold driving device, and upper mold driving device, lower mold are solid respectively It is fixed that upper mold is liftably mounted on the rack and is located at right above lower mold on the rack, upper mold driving device with it is upper Mold connection, vacuum and compressed air system are connected to lower mold, and upper mold bottom surface is equipped with forming cavity, it is characterised in that: described It is lower that a plurality of micro- stomata is provided between die top and bottom surface, and micro- stomata is uniformly distributed in lower die top, lower mold bottom surface It is connected to vacuum and compressed air system;Heating system is connect with lower mold.Due to replacing an atmosphere using a large amount of micro- stomatas 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.
