Description

Technical Field

[0001] The utility model belongs to the technical field of cup printing, and more specifically relates to a heat transfer printing coaster. Background Art

[0002] Heat transfer coasters are a type of auxiliary equipment specifically designed for the heat transfer process, primarily used to transfer designs or text onto items such as cups. During the heat transfer process, the coasters provide stable heat, ensuring the transferred design adheres firmly to the cup's surface, achieving a beautiful aesthetic effect. With the growing demand for personalized customization, heat transfer coasters are finding widespread use in gifts, souvenirs, and everyday items.

[0003] The design of heat-transfer coasters has made some progress. For example, Chinese Patent Publication No. CN217803852U discloses a coaster cable earmuff. This design protects the coaster's wiring by adding an earmuff body, extending its service life. Compared to traditional wrapping methods such as tape or heat shrink tubing, it is cleaner and more durable.

[0004] However, although this design solves the problem of protecting the wiring to a certain extent, the following defects still exist: First, the wire outlet of the coaster in the prior art is set on the outside, and the wire ends are exposed. They are easily bumped or pulled during use, causing damage to the line or loose wiring, which in turn affects the normal use of the coaster. This not only increases the user's maintenance costs, but may also have an adverse effect on the thermal transfer effect. Secondly, the wire outlet method of this coaster has certain limitations in machine design. Because the wire outlet end of the existing coaster is designed to be on the outside, it is difficult to meet the requirements of different machine designs. This limits the scope of application of thermal transfer coasters to a certain extent and also increases the difficulty and cost of machine design.

[0005] To this end, the utility model provides a heat transfer baking coaster. Utility Model Content

[0006] In view of the above-mentioned problems existing in the existing technology, the purpose of the present invention is to provide a heat transfer baking coaster to solve the problems existing in the existing baking coaster in the technology, such as the wire end is set on the outside, the wire end is exposed and easily bumped, and the customer has limitations in machine design.

[0007] The purpose of this utility model can be achieved through the following technical solutions:

[0008] A heat transfer baking coaster, the baking coaster having a three-layer nested structure, wherein the outer layer of the three-layer nested structure is a metal shell, the middle layer of the three-layer nested structure is a foamed silicone plate, and the inner layer of the three-layer nested structure is a silicone heating element. The foamed silicone plate is fixedly attached to and completely covers the inner wall surface of the metal shell, and the silicone heating element is fixedly attached to the inner side surface of the foamed silicone plate.

[0009] A threading hole is provided on the shell surface of the hardware shell. The silicone heating sheet includes a first silicone leather layer, a heating core, a second silicone leather layer and a glass fiber cloth layer stacked and fixed together from the outside to the inside. The heating core is connected to wires and cables. The wires and cables pass through the foamed silicone plate and through the threading hole of the hardware shell and extend out of the shell.

[0010] As a further preferred technical solution of the present invention, the overall shape of the hardware shell is a C-shaped cylinder, and the hardware shell is an integral piece made of stainless steel sheets through a bending process.

[0011] As a further preferred technical solution of the present invention, an L-shaped connecting portion is symmetrically bent and extended on both sides of the C-shaped opening of the hardware shell, and the L-shaped connecting portion of the hardware shell is provided with a first end face and a second end face, and circular and elliptical connecting holes are provided at both ends of the first end face, and elliptical connecting holes are provided at equal intervals on the second end face.

[0012] As a further preferred technical solution of the present invention, the first silicone leather layer and the second silicone leather layer are both high-temperature resistant leather materials.

[0013] As a further preferred technical solution of the present invention, the connection between the wires and cables and the foamed silicone plate is fixed by glue.

[0014] As a further preferred technical solution of the present invention, the wire and cable includes a metal shielding wire, a shielded heat shrink tubing, a connector shell and a connector terminal. One end of the metal shielding wire is electrically connected to the heating core, and the other end of the metal shielding wire passes through the shielded heat shrink tubing for heat shrinkage, and the core wire of the metal shielding wire is electrically connected to the connector terminal; the connector terminal is mounted on the connector shell.
