Description
Technical field
The utility model belongs to plastic product forming technical field, relates in particular to attemperating unit before a kind of plastic products blow molding.
Background technology
Blow molding is also known as hollow blow molding, and being make closed hot melt parison in a mold be blown into the method for hollow product by means of gas pressure, is a kind of plastic working method comparatively common at present.Moulding in the plastic products blow-molding process such as cup, the formation of parison and inflation are the cores of blow-molding process, parison is formed and the height of inflation quality directly affects the quality of vessel prepd, and the heating temperature of melt, cool time all will affect the shaping of parison and inflation quality.
Plastic products must be heated by heating furnace before blow molding, to ensure that plastics complete in forming process in the temperature range of technological requirement, current main flow heating furnace all adopts the mode of radiation heating, the control of furnace temperature is to detect heater temperature to realize, production process mainly relies on the experience of operator, state according to manufactured goods constantly adjusts, the result of such control causes the instability of production process, the true temperature of plastic sheet cannot be determined, occur in stove abnormal also cannot Timeliness coverage, finally will have a strong impact on production quality.
Utility model content
For this reason, technical problem to be solved in the utility model is that in prior art, plastic products adopt the mode of radiation heating to heat before blow molding, production process mainly relies on the experience of operator, inaccuracy is controlled, easily cause production process unstable, abnormal not easily Timeliness coverage, causes product quality poor in stove, thus proposes a kind of can automatically detection and attemperating unit before regulating the blow molding of in-furnace temperature.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The utility model provides temperature control equipment before a kind of plastic blow molding, it comprises, heater, the relay be electrically connected with described heater, the attemperating unit be electrically connected with described relay and the temperature measuring equipment be electrically connected with described attemperating unit, described heater comprises fixed head and is fixed on the heating watt on described fixed head.
As preferably, described fixed head is the fixed head of pair of opposing, leaves the space passed through for plastic plate between two pieces of fixed heads.
As preferably, described temperature measuring equipment is infrared temperature measuring head, for detecting the temperature of plastic plate and temperature information being sent to described attemperating unit.
As preferably, described attemperating unit is temp controlled meter, and the temperature information that described temperature measuring equipment records by described temp controlled meter and design temperature contrast, and determines whether to export control voltage.
As preferably, described two pieces of fixed heads are fixed on a support relatively.
As preferably, described heating watt is fixed on described fixed head by pin.
Technique scheme of the present utility model has the following advantages compared to existing technology: temperature control equipment before plastic blow molding described in the utility model, comprise, heater, the relay be electrically connected with described heater, the attemperating unit be electrically connected with described relay and the temperature measuring equipment be electrically connected with described attemperating unit, wherein, described heater is some heating watt of being fixed on fixed head.Plastic plate is when passing through the space between two pieces of fixed heads, temperature measuring equipment detects the temperature of plastic plate and this temperature data is transferred to attemperating unit, the temperature data that this records by attemperating unit compares with the temperature value preset, if the temperature of test is lower than preset temperature, attemperating unit then exports control voltage to relay, relay is by power stage extremely heating watt, and regulate and control heating power, described plastic plate is heated, after heating, plastic plate is delivered in mould and carries out blow molding.
Before plastic blow molding described in the utility model, temperature control equipment can detect plastic plate temperature automatically, and automatically control to heat plastic plate, the experience improved only by operator in conventional method constantly manually adjusts the present situation of in-furnace temperature, solve plastic plate to be heated uneven problem, this apparatus structure is simple, be easy to safeguard, control directly perceived, achieve production process data, low power consuming, avoid in production process instability and stove abnormal not easily by the problem of Timeliness coverage, heating process is stablized, the product quality finally obtained is good, the yield of product is greatly improved.
