Abstract
The utility model discloses a structure enabling temperature of a heat sealing face to be even. The structure enabling temperature of the heat sealing face to be even comprises a sealing head, a heating element and a bracket, wherein the heating element for heating is arranged inside the sealing head, and the region, corresponding to a member to be sealed, of the sealing head is a heat sealing region; the heat sealing region corresponds to a heating region of the heating element, and the heat sealing region is equal to or less than the heating region of the heating element; holes for heat dissipation are formed in a non heat sealing region of the sealing head, and the sealing head is fixed to the bracket. According to the structure enabling temperature of the heat sealing face to be even, temperature uniformity of the heat sealing region is controlled through adjusting the number, position and shape of holes in the sealing head, and the structure is simple, convenient to produce and low in cost.
Description
Technical field
The utility model relates to a kind of uniform structure of heat cover temperature that makes.
Background technology
In the Heat Sealing of flexible packaging, various film materials etc., to the temperature uniformity in heat-sealing region, require higher.But during end socket heating, due to the two ends rapid heat dissipation in heat-sealing region, middle part heat radiation is slow, often causes two ends, same heat-sealing region and middle part to have 3～6 ℃ of heal differentials.During Heat Sealing, meeting that temperature is on the low side causes sack, complex film not to be sealed up, excess Temperature can make material thawing cause sealing the problems such as edge leakage, so heat-sealing region non-uniform temperature can cause the phenomenons such as the same hot-seal such as packaging bag, complex film place is wrinkling, bubble, edge leakage.Conventional terms of settlement is at two ends, to increase attemperator at present, or the power of increase two ends heating resistor etc., current method comparison is complicated, and temperature uniformity control effect is undesirable, generally at 2～3 ℃.
Utility model content
The utility model is exactly in order to solve prior art above shortcomings, and a kind of uniform structure of regional temperature that makes to seal is provided, and it can well control the temperature uniformity in heat-sealing region, and simple in structure, easily manufactured, and cost is low.
The utility model is to adopt following technical proposals to realize:
Make the uniform structure of heat cover temperature, comprise end socket, heater element and support, be provided with a heater element for heating in the inside of described end socket, the region that described end socket and elements relative to be sealed are answered is heat-sealing region; Described heat-sealing region is corresponding with the heating region of heater element, and heat-sealing area size is equal to or less than the heating region of heater element; On the non-heat-sealing region of end socket, be provided with the hole for dispelling the heat, described end socket is fixed on support.
Described hole comprises at least one, its be arranged on end socket non-heat-sealing region the same face or not on coplanar.
Described hole is the hole of arbitrary shape, as rectangle, square, circular, oval, polygon or irregular shape.
The high-temperature zone, middle part in non-heat-sealing region is located in described hole; Described heat-sealing region is smooth flat, or is the plane with asperities.
Described heater element is the pipeline of heating pipe or heater strip or heater wire or the gas of aluminium foil temperature booster or inner intervenient heating or the liquid of heating; Described heater element is connected with thermal source.
Principle of work of the present utility model: element to be sealed is put on platform, and end socket is heated to design temperature, involution elements act is treated in heat-sealing region.During end socket heating, outside contacts with air, and dissipating area is large, rapid heat dissipation, and middle part does not contact with air, and relative heat radiation is slower, causes thus same heat-sealing regional temperature to be reduced gradually to two ends by middle part highest temperature.The utility model, by offering the dissipating area that slotted eye increases middle part in middle part, the non-heat-sealing region certain limit at end socket, dwindles the heal differential in same heat-sealing region.For the end socket of different size, by professional software, analyze and put into practice position, shape, the quantity of determining perforate, in order to guarantee that the temperature uniformity in same heat-sealing region is controlled in 1 ℃.
Advantage of the present utility model: 1, temperature is controlled evenly, the heal differential in heat-sealing region is controlled in 1 ℃; 2, simple in structure, easily manufactured, cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is left view of the present utility model.
Wherein, 1. end socket, 2. heater element, 3. heat-sealing region, 4. hole, 5. support, 6. wire.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment 1:
As Fig. 1, shown in Fig. 2, a kind of uniform structure of heat cover temperature that makes, comprise a rectangle end socket 1, heater element 2, support 5, in the inside of described end socket 1, be provided with one through its inside and the heater element 2 for heating, heat-sealing region 3 is a rectangle plane, described heat-sealing region 3 is positioned on the bottom surface or other at least one face of end socket 1, and the non-heat-sealing region at described end socket 1 is provided with the hole 4 for dispelling the heat, end socket 1 is fixed on support 5, by wire 6, give heater element 2 energisings, heater element 2 heatings, heat in heat-sealing region 3 to end socket 1, because end socket 1 external cooling is fast, middle part heat radiation is slow, cause end socket 1 medium temperature high, two ends temperature is lower, heat-sealing region 3 heal differentials reach 3～6 ℃, by the hole 4 arranging on end socket 1, the heal differential in heat-sealing region 3 is controlled in 1 ℃.
Embodiment 2:
Described end socket is a circle, and heat-sealing region is an annulus, and other,, with reference to embodiment 1, do not repeat them here.
Embodiment 3:
