Abstract
The utility model relates to an automatic pressure regulating mechanism of a plastic product hot wire fusing machine and aims to provide a mechanism which has the characteristics of simple structure, reliable work and low cost on the premise of automatically regulating the pressure between upper and lower pressing plates. The technical scheme is that the automatic pressure regulating mechanism of the plastic product hot wire fusing machine comprises a guide post standing on a frame and an upper pressing plate and a lower pressing plate capable of moving along the guide post. The automatic pressure regulating mechanism is characterized by also comprising an elastomer for applying a force to the upper pressing plate or the lower pressing plate so that the upper pressing plate and the lower pressing plate have opposite motion tendency.
Description
Technical field
The utility model relates to a kind of plastic parts hot line Heat sealing machine, especially can automatically regulate the automatic pressure governor motion of pressure between lower platen.
Background technology
Along with the fast development of economic society, increasing product has proposed high requirement to dustproof and waterproof; As solar water heater control box, street lamp control box, and household electrical appliances, automotive electronics, Industry Control box etc.Because the existing water-proofing treatment (all adopting the mode that rubber washer is set at interface) of this series products is difficult to reach requirement, thereby inventor has proposed a kind of hot line fusion method (steel wire of plastic parts seam crossing embedding being bonded together at two needs of plasthetics, and when two plastic parts are applied to certain pressure in opposite directions, to the logical certain electric current of steel wire, the seam crossing of plastic parts is melted, be bonded together after cooling).But the method has proposed high requirement to the pressure control of hot line Heat sealing machine, between to the front upper lower platen of steel wire energising heating, need to control a determining deviation; And when the seam crossing of plastic parts after steel wire energising heating is during in molten condition, the spacing between upper lower platen should have and reduces to be on a small quantity beneficial to melting position and fit tightly adhesion; Keeping making melting position cooling to obtain approved product under certain pressure afterwards.
Although above-mentioned requirements can reach by automatic control means, control technology relative complex, and need control appliance and the corresponding investment of some.
Utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes above-mentioned background technology, a kind of automatic pressure governor motion of plasthetics hot line Heat sealing machine is provided, this mechanism should be able to automatically regulate under the prerequisite of pressure between lower platen, has simple in structure, reliable operation and the low feature of cost.
The technical scheme in the invention for solving the above technical problem is: a kind of automatic pressure governor motion of plasthetics hot line Heat sealing machine, comprises and stand the guide pillar in frame and the top board that can move along guide pillar and lower platen; It is characterized in that this automatic pressure governor motion also comprises the elastomer that top board or the lower platen application of force is made to have between top board and lower platen move toward one another trend.
Described elastomer is spring; This spring is positioned between frame and lower platen and respectively frame and lower platen is applied to pressure on top surface.
Described spring is helical spring; This helical spring is set on the guide pillar position between frame and lower platen.
The beneficial effects of the utility model are: owing to having adopted elastomer to top board or the lower platen application of force, after top board and lower platen are drawn close in opposite directions, still there is pre-top set and press the mode of active force, not only meet the technological requirement of hot line fusion method, guarantee that after processing, the sealing property of product meets waterproof requirement completely, and whole mechanism is very simple, working stability is reliable, and cost of manufacture is also low, has general promotion prospect.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model.
Fig. 2 is the schematic cross-section of two plastic parts melting connecting portions.
The specific embodiment
Further illustrate below in conjunction with accompanying drawing.
In the automatic pressure governor motion of plasthetics hot line Heat sealing machine shown in the drawings, guide pillar 3 stands in frame 1, and upper and lower pressing plate is positioned in frame mutually accordingly; Visible in figure, lower platen 2 is positioned in frame, and 5 of top boards are equipped with the sliding sleeve matching with guide pillar, under actuating unit (preferably cylinder 6) orders about along guide pillar slide (also can locate top board, actuating unit orders about lower platen and slides along guide pillar).On described top board or lower platen, also dispose at least one pair of electrode 10 for switching on, this seam crossing to electrode alignment institute processing plastic product, to provide melt plastic cement required electric current.
The cross section of two plastic parts 8 melting connecting portions as shown in Figure 2 (as recommendation, on the faying face of two plastic parts, make respectively can be chimeric groove and boss), after steel wire 13 is imbedded wherein and plastic parts be combined as a whole.
Above structure is the conventional structure of hot line Heat sealing machine.
Improvement of the present utility model is the automatic pressure governor motion having configured top board or the lower platen application of force; This automatic pressure governor motion comprises the elastomer that makes to have between top board and lower platen move toward one another trend, and top board and lower platen all can be along guide pillar surface sliding (as recommendations, top board with on lower platen, the sliding sleeve coordinating with guide pillar should be installed respectively).
As preferably, described elastomer is spring (can be helical spring, air spring or torsion spring etc.); Position is set to be determined on a case-by-case basis.In the time that top board is movable part (top board ordered about along guide pillar by actuating unit slide up and down), this spring should be positioned between frame and lower platen and respectively frame and lower platen are applied to pressure on top surface.If when lower platen is movable part (lower platen ordered about along guide pillar by actuating unit slide up and down), this spring should be positioned between top board 7 and top board and (replace cylinder location in figure) and respectively top board and top board are applied to pressure on top surface.
Concrete force application location also can be selected to determine as requested; Can be arranged in the central part (as Fig. 1 double dot dash line frame 11 positions) of top board or lower platen, also can be at the position, both sides of top board or lower platen.
As recommendation, described spring adopts helical spring 12; This helical spring is set on the guide pillar position between frame and lower platen.
Operation principle of the present utility model is: when work, actuating unit order about lower on lower platen matched moulds, now, under spring-force driven dual, two plastic parts between upper lower platen keep certain thrust; Then steel wire energising heating makes the seam crossing melted by heating of plastic parts, because of melting position rigidity reduce thus under spring force pressure between two plastic parts and on draw close in opposite directions distance slightly between lower platen, make melting position fit tightly adhesion; Steel wire power-off is subsequently cooling, and two plastic parts are just completely tightly connected and are integrated.
In figure, also have: directly outsourcing of programmable power supply 9().
