[ Utility model ] content

In order to solve the above-mentioned technical problem that exists among the prior art, the utility model provides a hot melt machine heating die head solves the problem that the district that generates heat is inhomogeneous, the mould is heated inhomogeneous influence hot melt machine bonding effect, in order to realize above-mentioned purpose, the technical scheme of the utility model as follows:

the utility model provides a hot melt machine heating die head, includes hot plate and power connecting piece, evenly be provided with two piece at least first heater and two piece at least second heater on the hot plate, first heater with second heater vertically and horizontally staggered sets up, power connecting piece's one end with first heater and/or second heater are connected, the other end extends outside the hot plate and with external power source connection.

Further, the first heating wire and the second heating wire are crossed with each other to form a net structure.

Further, the first heating wire and the second heating wire are arranged perpendicular to each other.

Furthermore, the heating plate is provided with a plurality of cross-arranged concave parts, and the first heating wire and/or the second heating wire are/is arranged in the concave parts.

Further, the concave part is a groove arranged on the bottom surface of the heating plate.

Furthermore, the number of the power supply connecting pieces is at least two, and the first heating wire and the second heating wire are respectively connected with the power supply connecting pieces.

A hot melt machine comprising a hot melt machine heating die as described above.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a hot plate uses first heater and the second heater that vertically and horizontally staggered set up to replace current single heater, connects the power back through the power connecting piece, can make the thermally equivalent of whole hot plate, has solved the single heater that exists among the prior art and has generated heat, and the position of keeping away from the heater on the hot plate is heated less and leads to the hot plate to generate heat inhomogeneous problem, makes the hot plate evenly generate heat, and then increases the bonding effect of hot melt machine.

[ description of the drawings ]

FIG. 1 is a schematic structural view of the bottom surface of the heating plate of the present invention;

FIG. 2 is a cross-sectional view A-A of FIG. 1;

fig. 3 is a sectional view taken along line B-B of fig. 1.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-2, a heating die head of a hot melting machine comprises a heating plate 1 and a power supply connecting piece 4, wherein at least two first heating wires 2 and at least two second heating wires 3 are uniformly arranged on the heating plate, and the first heating wires 2 and the second heating wires 3 are arranged in a criss-cross manner; one end of the power supply connecting piece 4 is connected with the first heating wire, and the other end extends out of the heating plate 1 and is connected with an external power supply. During the use, the power passes through power connecting piece 4 and heats first heater wire 2, and first heater wire 2 realizes heating second heater wire 3 through setting up with second heater wire 3 alternately to the realization is to the even heating of hot plate 1, makes hot plate 1 be heated evenly.

Among the above-mentioned technical scheme, change single heater on the traditional hot plate into vertically and horizontally staggered's first heater 2 and second heater 3, and first heater 2 and second heater 3 all have two at least, make every position of hot plate be heated evenly, effectively solved the position that the heater was kept away from to current hot plate and heated inhomogeneous problem.

Furthermore, the first heating wire 2 and the second heating wire 3 are crossed with each other to form a net structure, so that the uniform heating effect of the heating plate 1 can be improved; preferably, the first heating wire 2 and the second heating wire 3 are perpendicular to each other; more preferably, the plurality of first heating wires 2 and the plurality of second heating wires 3 are equally spaced.
