Description

Technical Field

[0001] This utility model relates to the technical field of heat press machine accessories, and in particular to a heat press plate with a double-layered top shell. Background Technology

[0002] The ironing plate is one of the core components of a heat press machine. Its main function is to generate sufficient heat to transfer a pattern onto the fabric surface using a heat transfer method when pressure is applied. Therefore, the ironing plate is equipped with a heating element and a horizontal heat-conducting base plate. The heat generated by the heating element is transferred to the heat-conducting base plate, which then lowers to apply pressure to the fabric for the transfer. Typically, the ironing plate also has a top shell that attaches to the heat-conducting base plate. The top shell and the heat-conducting base plate form a closed box; the heating element is housed within this closed box. For example, the heating box 107 of a dual-station heat press machine, as described in utility model patent CN220535199U, contains a heating plate 111. If the heat press machine operates for an extended period, the heat generated by the heating plate 111 is also transferred to the top and sides of the heating box 107, posing a serious safety hazard to operators who accidentally touch it. There is an urgent need for a heat pressing plate that can prevent burns. Utility Model Content

[0003] The purpose of this invention is to solve the above problems and provide a double-layered top shell heat press plate.

[0004] The technical solution of this utility model is as follows: A double-layered heating plate includes a top shell assembly and a heat-conducting base plate that are snapped together. The top shell assembly and the heat-conducting base plate form a box structure. A heating element is integrally installed on the heat-conducting base plate. The heating element generates heat and transfers it to the heat-conducting base plate. The top shell assembly includes an inner top shell and an outer top shell that are snapped together. A heat-insulating cavity is left between the inner top shell and the outer top shell. The inner top shell is snapped onto the top of the heat-conducting base plate. A small amount of heat generated by the heating element is transferred to the inner top shell, but due to the insulation of the heat-insulating cavity, it will not continue to be transferred to the outer top shell. Therefore, the temperature of the outer top shell will be significantly lower than that of the inner top shell to avoid scalding the operator who accidentally touches it.

[0005] Preferably, the main body of the heat-conducting base plate is in the shape of a box; the inner top shell is in the shape of a lid; and there is a gap between the side of the heat-conducting base plate and the side of the inner top shell to reduce heat transfer from the heat-conducting base plate to the inner top shell.

[0006] Furthermore, the top four corners of the heat-conducting base plate are provided with vertical connecting posts; the top shell assembly also includes connecting screws and spacer nuts; the vertical connecting posts are provided with threaded holes A that match the connecting screws; the connecting screws pass through the outer top shell, spacer nuts, and inner top shell and are threadedly connected to the threaded holes A to realize the connection between the outer top shell, inner top shell, and heat-conducting base plate; by adjusting the number or size of the spacer nuts, the size of the heat insulation cavity can be changed, thereby adjusting the heat insulation effect of the heat insulation cavity.

[0007] Furthermore, the double-layered heat press plate of the top shell also includes a lower pressure plate, a mold spring, and a pressure-relieving screw; the center of the top of the outer top shell has a clearance hole that matches the lower pressure plate; the lower pressure plate is positioned directly above the clearance hole, applying downward pressure to the heat-conducting base plate; the area below the clearance hole on the heat-conducting base plate has a rectangular arrangement of vertical connecting posts B; the vertical connecting posts B have threaded holes B corresponding to the pressure-relieving screws; the pressure-relieving screws pass through the corner of the lower pressure plate, the mold spring, the inner top shell, and are threadedly connected to the threaded holes B; the clearance hole can serve as a heat dissipation vent for the heat insulation cavity, preventing the outer top shell from overheating. When the lower pressure plate presses down, it is through the mold spring acting on the heat-conducting base plate. When the heat-conducting base plate presses against the fabric, the mold spring will compress to a certain extent to buffer the impact force brought by the lower pressure plate, while the heat-conducting base plate applies pressure smoothly to the fabric surface. The clearance hole allows the lower pressure plate to pass through; thus, the heat insulation cavity can avoid compression deformation, achieving a stable heat insulation effect.

[0008] Furthermore, both vertical connecting column A and vertical connecting column B extend beyond the top of the heat-conducting base plate, maintaining a certain distance from the heat-conducting base plate to reduce heat transfer from the heat-conducting base plate to the inner top shell.

[0009] Furthermore, the double-layered heat press plate of the top shell also includes an adjusting nut; the adjusting nut is located between the mold spring and the inner top shell and is threadedly engaged with the buffer screw; adjusting the position of the adjusting nut relative to the buffer screw can change the preload of the mold spring, thereby adjusting the mold spring's ability to absorb impact force.

[0010] Furthermore, the lower pressure plate is equipped with a vertical guide shaft to guide the lower pressure plate as it presses down.

[0011] Preferably, the outer top shell has heat dissipation holes on its side for heat dissipation of the heat insulation cavity and to reduce the temperature of the outer top shell surface.

[0012] Furthermore, the top of the heat-conducting base plate is equipped with vertical grids to improve the pressure resistance of the guide base plate.

[0013] Furthermore, the bottom of the vertical grille is provided with a through hole; the heating element is a resistance wire, which passes through the through hole and reciprocates on the heat-conducting base plate; the through hole limits the resistance wire; the resistance wire is evenly distributed on the heat-conducting base plate so that heat can be evenly transferred to the heat-conducting base plate.

[0014] Furthermore, a terminal block is installed at the end of the resistance wire; the terminal block includes an insulating sleeve and an insulating cover; the insulating cover is snapped onto the insulating sleeve; the insulating sleeve is fitted onto the end of the resistance wire; a wiring notch is provided on the side of the insulating sleeve; the terminal block can prevent leakage of current from the heat-conducting base plate.

[0015] The beneficial effects of this utility model are as follows: The double-layered top shell pressing plate of this utility model has the following advantages:

[0016] (1) The heat insulation cavity of this utility model isolates the inner top shell from the outer top shell, so that the temperature of the outer top shell will be significantly lower than that of the inner top shell, so as to avoid burns to the operator who accidentally touches it.

[0017] (2) By adjusting the number or size of the spacer nuts, this utility model can change the size of the heat insulation cavity, thereby adjusting the heat insulation effect of the heat insulation cavity. Attached Figure Description

The top shell assembly and the heat-conducting base plate 2 form a box structure. A heating element 21 is integrally installed on the heat-conducting base plate 2. The heating element 21 generates heat and transfers it to the heat-conducting base plate 2. The top shell assembly includes an inner top shell 11 and an outer top shell 12 that are snapped together. A heat-insulating cavity 13 is left between the inner top shell 11 and the outer top shell 12. The inner top shell 11 is snapped onto the top of the heat-conducting base plate 2. A small amount of heat generated by the heating element 21 is transferred to the inner top shell 11, but due to the insulation of the heat-insulating cavity 13, it will not continue to be transferred to the outer top shell 12. Therefore, the temperature of the outer top shell 12 will be significantly lower than that of the inner top shell 11 to avoid burns to operators who accidentally touch it.

[0030] Compared with the prior art, the present invention is provided with a heat insulation cavity 13 to prevent the inner top shell 11 from transferring heat to the outer top shell 12, so that the temperature of the outer top shell 12 will be significantly lower than that of the inner top shell 11, thereby avoiding burns to operators who accidentally touch it.

[0031] The main body of the heat-conducting base plate 2 is in the shape of a box; the inner top shell 11 is in the shape of a lid; a gap 14 is left between the side of the heat-conducting base plate 2 and the side of the inner top shell 11, which can reduce the heat transfer from the heat-conducting base plate 2 to the inner top shell 11.

[0032] The top four corners of the heat-conducting base plate 2 are provided with vertical connecting posts A 22; the top shell assembly also includes connecting screws 15 and spacer nuts 16; the vertical connecting posts A 22 are provided with threaded holes A 221 that match the connecting screws 15; the connecting screws 15 pass through the outer top shell 12, spacer nuts 16, and inner top shell 11 and are threadedly connected to the threaded holes A 221 to realize the connection between the outer top shell 12, the inner top shell 11, and the heat-conducting base plate 2; by adjusting the number or size of the spacer nuts 16, the size of the heat insulation cavity 13 can be changed, thereby adjusting the heat insulation effect of the heat insulation cavity 13.

[0033] The top shell assembly also includes a protective sleeve 17 and a protective cover 18; the bottom of the protective sleeve 17 is closed; the connecting screw 15 passes through the bottom of the protective sleeve 17; the protective cover 18 is fastened to the top of the protective sleeve 17; the protective sleeve 17 and the protective cover 18 cooperate with each other to prevent the bolt head of the connecting screw 15 from being exposed.

[0034] The double-layered pressing plate of the top shell also includes a lower pressure plate 3, a mold spring 4, and a pressure-relieving screw 5; the top center of the outer top shell 12 is provided with a clearance hole 121 that matches the lower pressure plate 3; the lower pressure plate 3 is positioned directly above the clearance hole 121, applying downward pressure to the heat-conducting base plate 2; the area on the heat-conducting base plate 2 below the clearance hole 121 is provided with a rectangular arrangement of vertical connecting posts B 23; the vertical connecting posts B 23 are provided with threaded holes B 231 that match the pressure-relieving screw 5; the pressure-relieving screw 5 passes through the corner of the lower pressure plate 3, the mold spring 4, the inner top shell 11, and is threadedly connected to the threaded hole B 231; the clearance hole 121 can serve as a heat dissipation vent for the heat insulation cavity 13, preventing the outer top shell 12 from overheating. When the lower pressure plate 3 presses down, it is through the mold spring 4 that it acts on the heat-conducting base plate 2. When the heat-conducting base plate 2 presses against the fabric, the mold spring 4 will be compressed to buffer the impact force brought by the lower pressure plate 3, while the heat-conducting base plate 2 applies pressure smoothly to the fabric surface. The clearance hole 121 allows the downward pressing plate 3 to pass through; thus, the heat insulation cavity 13 can avoid compression deformation and achieve a stable heat insulation effect.

[0035] Both vertical connecting column A 22 and vertical connecting column B 23 extend beyond the top of the heat-conducting base plate 2 and maintain a certain distance from the heat-conducting base plate 2 to reduce the heat transfer from the heat-conducting base plate 2 to the inner top shell 11.

[0036] The double-layered heat press plate of the top shell also includes an adjusting nut 6; the adjusting nut 6 is located between the mold spring 4 and the inner top shell 11 and is threadedly engaged with the buffer screw; adjusting the position of the adjusting nut 6 relative to the buffer screw can change the preload of the mold spring 4, thereby adjusting the ability of the mold spring 4 to absorb impact force.

[0037] The lower pressure plate 3 is equipped with a vertical guide shaft 31, which provides guidance for the lower pressure plate 3 to press down.

[0038] The outer top shell 12 has heat dissipation holes 122 on its side for heat dissipation of the heat insulation cavity 13 and to reduce the temperature of the surface of the outer top shell 12.

[0039] The top of the heat-conducting base plate 2 is provided with a vertical grid 24 to improve the pressure resistance of the guide base plate.

[0040] The bottom of the vertical grille 24 is provided with a through hole 241; the heating element 21 is a resistance wire, which passes through the through hole 241 and is in a reciprocating state on the heat-conducting base plate 2; the through hole 241 limits the resistance wire; the resistance wire is evenly distributed on the heat-conducting base plate 2 so that the heat can be evenly transferred to the heat-conducting base plate 2.

[0041] The working principle of this embodiment is as follows: The top shell assembly and the heat-conducting base plate 2 form a box structure; the heating element 21 generates heat and transfers it to the heat-conducting base plate 2; a small amount of the heat generated by the heating element 21 is transferred to the inner top shell 11, but due to the insulation of the heat-insulating cavity 13, it will not continue to be transferred to the outer top shell 12; therefore, the temperature of the outer top shell 12 will be significantly lower than that of the inner top shell 11, to avoid burns to operators who accidentally touch it. A gap 14 is left between the side of the heat-conducting base plate 2 and the side of the inner top shell 11, which can reduce the heat transfer from the heat-conducting base plate 2 to the inner top shell 11. By adjusting the number or size of the spacer nuts 16, the size of the heat-insulating cavity 13 can be changed, thereby adjusting the heat insulation effect of the heat-insulating cavity 13. The clearance hole 121 can serve as a heat dissipation vent for the heat-insulating cavity 13, preventing the outer top shell 12 from overheating. When the lower pressure plate 3 is pressed down, it is through the mold spring 4 that the heat-conducting base plate 2 is acted upon. When the heat-conducting base plate 2 presses against the fabric, the mold spring 4 is compressed to buffer the impact force from the downward pressure of the lower pressure plate 3, while the heat-conducting base plate 2 applies pressure smoothly to the fabric surface. The clearance hole 121 allows the downward pressure plate 3 to pass through; thus, the heat insulation cavity 13 can avoid compression deformation and achieve a stable heat insulation effect. Adjusting the position of the adjusting nut 6 on the buffer screw can change the preload of the mold spring 4, thereby adjusting the ability of the mold spring 4 to absorb impact force.
