The beneficial effects of the utility model are: for having impression when solving handle and composite membrane electric welding, bond unstable problem and improve bag speed, select first to carry out preheating (selecting the preheat temperature be applicable to according to the handle of unlike material) to handle before handle spot welding, go again to bond with composite membrane after the uniform temperature that allowed handle have, do not need to absorb a lot of heat to be bonded together with composite membrane, the spot welding time will effectively shorten, heat-sealing temperature and heat-sealing pressure can regulate in the reasonable scope, would not impression be there is in composite membrane and handle when bonding, both ensured that the sack made was attractive in appearance, also reduce the spot welding time simultaneously, improve bag efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is schematic diagram one of the present utility model;
Fig. 2 is schematic diagram two of the present utility model;
Fig. 3 is the schematic diagram that handle point is welded on composite membrane;
Fig. 4 is the finished product schematic diagram that handle is welded on bag completely.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 4, the utility model is the handle preheating device of a kind of meter of bag weldering handle bag, comprise frame 1 and heater, frame 1 is provided with a heat tunnel 2 slipped over for handle 0, heater is used for heating the handle 0 through heat tunnel 2.Impression is had with during composite membrane 10 electric welding for solving handle 0, bond unstable problem and improve bag speed, select first to carry out preheating (selecting the preheat temperature be applicable to according to the handle 0 of unlike material) to handle 0 before handle 0 spot welding, allow handle 0 had uniform temperature after go again to bond with composite membrane 10, do not need to absorb a lot of heat to be bonded together with composite membrane 10, the spot welding time will effectively shorten, heat-sealing temperature and heat-sealing pressure can regulate in the reasonable scope, would not impression be there is in composite membrane 10 and handle 0 when bonding, both ensured that the sack made was attractive in appearance, also reduce the spot welding time simultaneously, improve bag efficiency.
As shown in the figure, in order to improve pre-heat effect, a through hole 3 is provided with bottom heat tunnel 2, lower heater can directly be contacted with handle 0, through hole 3 lateral dimension is less than the lateral dimension of handle 0, through hole 3, in longitudinally can cover multiple handle 0 simultaneously, makes heater can heat multiple handle 0 simultaneously.
As shown in the figure, heater specifically can adopt following embodiment, comprises heater and lower heater, upper heater is positioned at above through hole 3, for heating handle 0 top, lower heater is positioned at below through hole 3, for heating handle 0 bottom; Upper heater comprises the first preheating table 41, guide rod 42, spring 43 and the first heating tube 44, guide rod 42 one end is slidably arranged in frame 1, the other end is fixedly connected with the first preheating table 41, it is inner that first heating tube 44 is arranged on this first preheating table 41, spring 43 one end is resisted against in frame 1, the other end is resisted against on the first preheating table 41, and the first preheating table 41 is positioned at above through hole 3, and the first preheating table 41 can cover multiple handle 0 simultaneously; Lower heater comprises the second preheating table 51 and the second heating tube 52, second preheating table 51 and to be arranged in frame 1 and to be positioned at through hole 3, and the second heating tube 52 is arranged in the second preheating table 51, and the second preheating table 51 can cover multiple handle 0 simultaneously.Adopt the concrete action of heater of said structure as follows, at drive unit, (drive unit adopts existing mature technology to handle 0, be not described further at this) effect under move forward with the form of stepping, through through hole 3 position, under the effect of spring 43, the first preheating table 41 acts on handle 0, and handle 0 and the second preheating table 51 are compressed, handle 0 is heated in the gap of stepping by the first preheating table 41 and the second preheating table 51, because the first preheating table 41 and the second preheating table 51 can cover multiple handle 0, therefore each handle 0 can by the first preheating table 41 and the second preheating table 51 heating for multiple times through through hole 3, and then reach, before spot welding, its temperature is increased to setting requirement.
Concrete pinpoint welding procedure is as follows, handle 0 is delivered between two-layer composite membrane 10 after preheating, then instantaneous by the centre position of handle 0 and composite membrane 10 spot welding by spot welding device, the two sides of handle 0 all has two positions and composite membrane 10 spot welding to live, namely relative position between the handle and composite membrane 10 of a postwelding is fixed, and then the handle 0 of a postwelding is delivered to subsequent handling with composite membrane 10 and welds comprehensively.
