Abstract
The utility model specifically relates to a sectional power temperature compensation heating rod which is applied to non-PVC flexible package infusion solution production lines. The sectional power temperature compensation heating rod comprises a heating rod housing and at least two sections of heater strip-wrapped matrix magnesium oxide rods. The magnesium oxide rods are located in the heating rod housing, a heater strip is wrapped around the periphery of each magnesium oxide rod, two copper rods which are independent from each other pass through the magnesium oxide rods, the two copper rods are pressed onto two outgoing lines respectively, the starting point of each heater strip and one copper rod of the two copper rods are welded together, the ending point of each heater strip and the other copper rod of the two copper rods are welded together, and magnesium oxide power is filled into the gap between the heating rod housing and the magnesium oxide rods. By adopting the sectional structure, the power on one section can be different from the power on the other section, so the power of each section of magnesium oxide rod can be changed according to the distribution character of die surface temperature to achieve the purpose of die temperature compensation so as to improve the uniformity of the surface temperature of a welding die. By reducing the diameter of the heater strips and reducing the wrapping clearance of the heater strips, the heating efficiency of the heating rods can be improved, and the service life of the heating rods is prolonged.
Description
Technical field
The utility model relates to a kind of segmented power temperature-compensating heating rod, is applied in the weld molds such as the welding of non-PVC-soft packing large infusion production line bag forming, lettering welding, multi-cavity bag rosin joint.
Background technology
At present, non-PVC-soft packing infusion solutions high speed development, moulds such as bag forming welding, lettering welding, multi-cavity bag rosin joint adopt slab construction more, and welding region is big, and mould structure is complicated, and it is very inhomogeneous to cause mold surface temperature to distribute, and has a strong impact on welding quality.Non-PVC-soft packing infusion solutions bag type basic fixed mainly is divided into 100ml, 250ml, 500ml, 1000ml, 2000ml, 300ml.The length of corresponding welding region, broadband be basic fixed also.Temperature Distribution is inhomogeneities clocklike, if temperature can not get compensation, the welding of non-PVC film material is easy to generate hidden danger, can not well be suitable for the high-end infusion film material of welding temperature window narrows.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can improve the uniformity of weld mold surface temperature and the segmented power temperature-compensating heating rod that prolongs useful life.
The utility model solves the technical scheme that its technical problem adopted: described segmented power temperature-compensating heating rod; It is characterized in that: comprise that heating rod shell and at least two sections heater strips twine matrix magnesia rod; The magnesia rod is arranged in the heating rod shell, and the periphery of magnesia rod is wound with heater strip, and the inside of magnesia rod is installed with two separate copper rods; Two copper rods respectively with two lead-out wire crimping; The initiating terminal of heater strip and wherein copper rod welding, end and other copper rod welding are filled magnesium oxide powder in the space between heating rod shell and the magnesia rod.
Voltage between described two copper rods is 220V.
Described copper rod diameter is 0.5mm ~ 3mm.
Because the voltage 220V between two copper rods, voltage also is 220V between the heater strip that is therefore twined on every section magnesia rod, that is: the heater strip on the multistage magnesia rod is a parallel-connection structure.This heating rod can change each section power according to the distribution character of mold surface temperature through segmental structure, reaches the purpose of compensating mold surface temperature distribution, to improve the uniformity of weld mold surface temperature.Through changing the size that heater strip diameter or length (promptly twine the gap, it is short more to twine the big more heater strip in gap) can be regulated every section magnesia rod power easily.
When the diameter of inner heater strip diminished or twines gap smaller, with the heating rod of constant power, the electric current in the heater strip reduced, thereby improves greatly the heating efficiency and the useful life of heating rod.
Described heating rod shell adopts stainless-steel seamless pipe, thickness of steel pipe 0.5mm ~ 3mm.
The cylindricity of described heating rod shell external diameter is less than 0.1mm.Wherein, the external diameter of heating rod shell is processed through grinding machine, thereby cylindricity is controlled in the 0.1mm.
The beneficial effect that the utility model had is:
This heating rod is through adopting segmental structure, and every section power can be different, thereby can change the power of each section magnesia rod according to the distribution character of mold surface temperature, reaches the purpose of compensating mold temperature, to improve the uniformity of weld mold surface temperature; Through reducing the heater strip diameter, reducing heater strip winding gap, can improve the heating efficiency of heating rod, prolong the useful life of heating rod; Adopt welding between copper rod and the heater strip, can guarantee the reliable connection of heater strip.

Fig. 1 is the structural representation of the utility model.
Among the figure: 1, heating rod shell; 2, magnesia rod; 3, heater strip; 4, copper rod; 5, copper rod; 6, magnesium oxide powder; 7, lead-out wire.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; Segmented power temperature-compensating heating rod comprises that heating rod shell 1 and at least two sections heater strips twine matrix magnesia rod 2, and magnesia rod 2 is arranged in heating rod shell 1; The periphery of magnesia rod 2 is wound with heater strip 3; The inside of magnesia rod 2 be installed with two separate copper rods, 4,5, two copper rods respectively with 7 crimping of two lead-out wires, the initiating terminal of heater strip 3 and wherein copper rod 4 welding; End and 5 welding of an other copper rod are filled magnesium oxide powder 6 in the space between heating rod shell 1 and the magnesia rod 2.
Wherein: the voltage between described two copper rods is 220V; Described copper rod diameter is 0.5mm ~ 3mm; Heating rod shell 1 adopts stainless-steel seamless pipe, thickness of steel pipe 0.5mm ~ 3mm; The external diameter of heating rod shell 1 is through grinding machine processing, and cylindricity is controlled in the 0.1mm.
During making; Earlier heater strip 3 is wrapped on the magnesia rod 2, and the two ends of heater strip are welded with two copper rods respectively, after heater strip 3 welding are good; Magnesia rod 2 is penetrated in the seamless steel pipe (being heating rod shell 1) magnesia rod 2 and the middle magnesium oxide powder 6 of filling of seamless steel pipe.
Because the heater strip 3 on the multistage magnesia rod 2 is a parallel-connection structure; Therefore gross power is the segmented power sum, according to actual needs, and during making; Change the diameter of every section heater strip 3 or twine the gap; Can change the size of every section magnesia rod 2 power, thereby play the effect of compensating mold Temperature Distribution, to improve the uniformity of weld mold surface temperature.
When the diameter of inner heater strip 3 diminished or twines gap smaller, with the heating rod of constant power, the electric current in the heater strip reduced, thereby improves greatly the heating efficiency and the useful life of heating rod.
