The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0037] like Figure 1 , 2 As shown in , 3, 4, and 5, a novel coil heating device comprises a bracket 10, wherein at least one heating chamber 20 in a "U"-shaped structure is arranged inside the bracket 10, at least one transmission wheel 22 away from each other is arranged on both sides of the opening end of the "U" shape, and a guide wheel 21 is arranged at the bottom of the "U" shape;

[0038] The guide wheel 21 includes a rotating shaft 211 connected to the bracket 10, and two winding wheels 212 are arranged on the rotating shaft 211 and are separated from each other. The outer diameter of the winding wheel 212 is larger than the outer diameter of the rotating shaft 211, and the winding wheel 212 can rotate relative to the bracket 10;

[0039] The heating chamber 20 is provided with an air outlet 50 and a heating component 30 , and the heating component 30 includes a heating body 31 .

[0040] like Figure 5 As shown, in this embodiment, the coil 80 passes through the heating chamber 20 in a "U" shape from the transmission wheel 22 → the coil wheel 212 → the transmission wheel 22 in sequence, and the two sides of the pattern surface of the coil 80 are respectively in contact with the two coil wheels 212, and the pattern area passes through the middle of the two coil wheels 212 without contacting the coil wheels 212. The heating element 31 is in the middle of the "U" shape, that is, both sides of the heating element 31 are the pattern surfaces of the coil 80 that need to be heated, thereby improving the heating efficiency, and the coil wheel 212 will not rub against the pattern surface.

[0041] According to the tension and deformation of the coil, the number of coil wheels 212 can be increased to 3 or more. It should be noted that the pattern area needs to avoid the coil wheel 212 to prevent the coil wheel 212 from deforming the pattern.

[0042] Further, such as Figure 1 , 5 As shown, since hot air has lift, a vertical "U"-shaped heating chamber design is adopted, with the opening facing upward, and the exhaust port 50 is set at the open end of the "U"-shaped top, which is conducive to the discharge of volatiles generated by heating such as hot melt powder and coiled materials; the exhaust port 50 can be connected to an external air treatment device. The coiling wheel 212 is below the transmission wheel 22, and the coiling wheel 212 is aligned with the center of the "U"-shaped opening, and the exhaust port 50 is close to the open end of the heating chamber 20.

[0043] In order to increase the length of the heating zone, a plurality of "U"-shaped heating chambers connected in series (arranged in a wave shape) may also be provided.

[0044] Further, such as Figure 3 , 4 As shown in FIG. 5 , in order to support the coil 80, a pulley 213 is provided at each end of the rotating shaft 211.

The inner side of the conveyor belt 40 is sequentially connected to all the transmission wheels 22, and the two sides of the conveyor belt 40 are respectively connected to the pulley 213.

[0046] In this embodiment, the two sides of the conveyor belt 40 are respectively connected to the pulley 213, and the two sides of the coil 80 are connected to the coil wheel 212. The outer diameter of the pulley 213 is larger than the outer diameter of the coil wheel 212 to avoid mutual friction between the coil 80 and the conveyor belt 40 at the position of the guide wheel 21.

[0047] Furthermore, since the heating chamber is curved and closed, in order to facilitate guiding the coil 80 to pass through the transmission wheel 22 and the guide wheel 21, a coil guide clamp 41 is provided on the outer side of the conveyor belt 40.

[0048] When in use, the conveyor belt 40 can be set to run synchronously with the coil 80 at the same speed to reduce the friction between the conveyor belt 40 and the coil 80; according to the material and tension conditions, the conveyor belt 40 can also be set to be stationary and only play a supporting role. In this embodiment, the conveyor belt 40 only runs when guiding the coil 80 to load, and does not rotate during normal use.

[0049] Furthermore, in order to make the roll guide clamp 41 stop accurately at a position convenient for clamping during loading, a sensor 42 fixed to the bracket 10 is provided on one side of the conveyor belt 40 , and the sensor 42 corresponds to the movement trajectory of the roll guide clamp 41 .

[0050] Furthermore, in order to reduce the rotation of the automatic driving conveyor belt 40 during loading, at least one of the driving wheels 22 is connected to the driver 23 in a driving manner.

[0051] The driver in this embodiment is a rotary motor.

[0052] Further, such as Figure 1 As shown, the heating component 30 includes heating bodies 31 evenly arranged inside the heating chamber 20 .

[0053] The heating element 31 in this embodiment is an infrared electric heating tube, and electric heating materials such as resistance wires can also be selected as the heating element as needed.

[0055] The bellows 34 has a heating element 31 disposed therein, and the bellows 34 is provided with a plurality of hot air ports 341 for connecting the interior of the bellows 34 with the heating chamber 20 .

[0056] In this embodiment, the hot air is blown uniformly from bottom to top toward the heating chamber 20 through the hot air outlet 341 , and then circulated under the pressure of the fan 33 .

[0057] Furthermore, in order to prevent the circulating air from contaminating the heated objects such as patterns and coils and to reduce pollutant emissions, a filter 32 is further provided on the air duct 35 .

[0058] The filter 32 in this embodiment is an activated carbon filter, and filters such as water curtain filter and catalytic filter can also be selected or used in combination according to the situation.

[0059] Further, such as Figure 4 As shown, in order to prevent the conveyor belt 40 from deviating, a guide strip 43 is provided on the conveyor belt 40 , and a guide groove 221 corresponding to the guide strip 43 is provided on the driving wheel 22 .

[0060] Furthermore, in order to improve the temperature resistance of the conveyor belt, the material of the conveyor belt 40 is Teflon or metal material.

[0061] In order to reduce friction, avoidance holes or mesh-structured conveyor belts can be provided on the conveyor belt.

[0062] like Figure 5 As shown, a powder shaking and color fixing machine includes the above-mentioned coil heating device, and a powder sprinkling device 60 is provided on one side of the heating chamber 20, and a winding device 70 is provided on the other side.

[0063] When in use, the powder sprinkling device 60 sprinkles hot melt powder on the printed pattern of the thermal transfer film, and then the hot melt powder adsorbed on the thermal transfer film pattern is melted in the heating chamber 20 and solidified on the thermal transfer film, and finally the winding device 70 winds up the thermal transfer film; as needed, a powder shaking device can be set between the powder sprinkling device 60 and the heating chamber 20, and a thermal transfer film cooling device can also be set between the heating chamber 20 and the winding device 70.

[0064] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
