Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer equipment, in particular to a heat press, and is particularly suitable for printing flat and curved parts of substrates. Background Art

[0002] The heat press involved in this application is a device that generates heat through a heat plate component, and the user applies pressure to transfer the layer on the transfer paper to the substrate. It generally includes a gripping part and a heat pressing plate component, and the user controls the heat press through the gripping part. Existing heat presses of this type, such as the heat press disclosed in CN218020701U, have a flat heat pressing surface on the heat pressing plate component, which is only suitable for heat transfer to the flat part of the substrate, but not for heat transfer to the curved part. The user needs to buy another heat press with a concave heat pressing surface to complete the heat transfer to the curved part of the substrate, which increases the cost; in addition, the frequency of use of the heat press with a curved heat pressing surface by general users is much lower than that of the heat press with a flat heat pressing surface, so the utilization rate of the heat press with a curved heat pressing surface is low.

[0003] This section does not purport to be all prior art. Summary of the invention

[0004] This section provides a general summary of the application, and is not a comprehensive disclosure of its full scope or all of its features.

[0005] The purpose of the present application is to overcome the problem in the prior art that the flat part and the curved part of the printing material need to be realized by two heat presses, resulting in high cost and low overall utilization rate. One solution of the present application is to solve this problem by configuring a concave curved pressing part on the pressing surface.

[0006] A heat press provided in one aspect of the present application comprises a main body, a gripping portion and a heat plate; wherein the gripping portion is constructed on the main body, the heat plate is constructed at the lower part of the main body, and is constructed with a pressing surface and at least one curved pressing portion, wherein the at least one curved pressing portion is defined by a recessed portion at the lower end of the heat plate.

[0007] By constructing at least one concave curved pressing part on the pressing surface, when the user needs to perform thermal transfer on the arc-shaped part, it can be achieved through the curved pressing part. Therefore, the heat press machine of the present application realizes both flat thermal transfer operations and curved thermal transfer operations, with good economy and high overall utilization rate.

[0008] In some examples, at least one curved pressing part is connected to the side of the hot plate. Since at least one curved pressing part is connected to the side of the hot plate, the curved pressing part can move relative to the arc-shaped part of the printing material during operation, so as not to be limited by the area size of the curved pressing part.

[0009] In some examples, at least one curved pressing part is connected to the side of the hot plate and arranged at an angle relative to the pressing surface, so that the vertex of the outer end of the curved pressing part is higher than the intersection of its inner end and the pressing surface. In this way, when the curved pressing part moves relative to the arc-shaped part of the printing material, the printing material and the pressing surface are avoided at an angle to avoid interfering with the movement of the curved pressing part.

[0010] In some examples, at least one curved pressing part is connected to the side of the hot plate and arranged at an angle relative to the pressing surface, and the height of the curved pressing part relative to the pressing surface increases from the inside to the outside. With the above solution, the surface of the curved pressing part increases, and the user can operate the hot press machine to offset the curved pressing part within an angle range during operation, which does not interfere with the pressing surface and is convenient for operation.

[0011] In some examples, at least one curved pressing portion is connected to a side of the heat plate and is arranged at an angle relative to the pressing surface, and surfaces of the curved pressing portions have the same curvature.

[0012] In some examples, the curved pressing portion is disposed at the rear of the heat plate and communicates with the rear end.

Since the curved pressing part is constructed at the rear of the hot plate, during use, the interference and influence on the most commonly used forward and lateral movements of the pressing surface are minimized; on the other hand, the power cord of the hot press is generally at the lower rear part of the main body, and the curved pressing part is constructed at the rear of the hot plate, which has little influence on the use and appearance of the product.

In this improvement, the heating element extends to the curved pressing part, which can ensure the working temperature of the curved pressing part and ensure the thermal transfer effect.

[0052] In some examples, at least one curved surface pressing part 3.1 is connected to the side of the hot plate 3. Since at least one curved surface pressing part 3.1 is connected to the side of the hot plate 3, the curved surface pressing part 3.1 can move relative to the arc-shaped part of the printing material during operation, so as not to be limited by the area size of the curved surface pressing part 3.1. Figures 1 to 7 The curved pressing part 3.1 is connected to the side of the hot plate 3.

[0053] In some examples, at least one curved pressing part 3.1 is connected to the side of the hot plate 3 and arranged at an angle relative to the pressing surface 30, so that the vertex 3.11 of the outer end of the curved pressing part 3.1 is higher than the intersection 3.12 of its inner end and the pressing surface 30. In this way, when the curved pressing part 3.1 moves relative to the arc-shaped part of the printing material, the printing material and the pressing surface 30 are avoided at an angle to avoid interfering with the movement of the curved pressing part 3.1. Figures 1 to 7 The curved pressing portion 3.1 is connected to the side of the hot plate 3 and is arranged at an angle relative to the pressing surface 30.

[0054] In some examples, at least one curved pressing part 3.1 is connected to the side of the hot plate 3 and arranged at an angle relative to the pressing surface 30, and the height of the curved pressing part 3.1 relative to the pressing surface 30 increases from the inside to the outside.

[0055] See also Figure 5 In some examples, at least one curved pressing part 3.1 is connected to the side of the hot plate 3 and arranged at an angle relative to the pressing surface 30, and the surfaces of the curved pressing parts 3.1 have the same curvature.

[0056] See also Figures 1 to 10 In some examples, the curved pressing portion 3.1 is disposed at the rear of the hot plate 3 and connected to the rear end. Being disposed at the rear of the hot plate 3 has less impact on the daily use of the pressing surface 30 and also has less impact on the product appearance.

[0057] See also Fig.15 In some examples, at least two ends of the curved pressing part 3.1 are respectively connected to the side of the hot plate 3, and the printing object can move relative to the two ends of the curved pressing part 3.1, which is convenient for use and operation.

The number can also be 2 or more as required. Fig.14 There are two curved surface pressing parts 3.1, one is spherical and the other is ellipsoidal.
