The bracket is arranged on the base, and a driving device is arranged on the machine base to drive the heat press plate assembly to rise and fall, thereby realizing heat transfer operation on the objects placed on the bracket.

[0005] Temperature, time and pressure are the three most important factors of a heat press. The control of temperature and time is easy to achieve through the control module, but the pressure is difficult to control accurately. Usually a fixed pressure is set, and the pressure is stopped when the hot press plate assembly descends toward the support to the maximum pressure. The pressure is controlled by the drive device.

[0006] The inventors have found through investigation and research that with existing heat presses of this type, users cannot set different pressures according to the thickness and type of the material, resulting in unsatisfactory transfer effects and a poor experience. Summary of the invention

[0007] The purpose of the utility model is to solve the problem that users of existing heat press machines cannot set the pressure of the heat press plate assembly according to their needs, resulting in unsatisfactory transfer effect and poor experience. The problem is solved by installing a pressure sensor at the support point and the control module calibrating the pressure of the heat press plate assembly according to the specified pressure parameters combined with the feedback of the pressure sensor.

[0010] The hot press plate assembly is arranged above the base, and the driving mechanism drives the hot press plate assembly to rise and fall relative to the base through a screw-nut pair. The support is connected to the base through a supporting fulcrum to provide support for the thermal transfer object. The pressure detection element is installed on the base and connected to the supporting fulcrum to detect the pressure applied by the hot press plate assembly to the support. The control module controls the driving mechanism to drive the hot press plate assembly to apply pressure downward according to the pressure data configured by the user, and adjusts the output of the driving mechanism according to the feedback of the pressure detection element so that the pressure borne by the support matches the pressure data configured by the user.

[0011] Compared with the prior art, the control module of the utility model can accurately adjust the pressure borne by the detection bracket through the pressure detection element, so that the actual pressure applied to the thermal transfer object matches the pressure data configured by the user, thereby improving the thermal transfer quality and user experience.

[0012] Further, the user configured pressure data is input by a user control having a plurality of settings for pressure calibration according to a material type of the thermal transfer object or one or more characteristics of the thermal transfer object, wherein the user control is positionable to the plurality of settings.

[0013] In another embodiment, the user control is a button-type electronic component, a rotary encoder or a touch-sensitive control configured on the automatic heat press.

[0014] In another embodiment, the user control is a key-type electronic component, a rotary encoder or a touch-type control configured on an external terminal that can be communicatively connected to the control module.

[0015] In another embodiment, the user control is configured in the local storage of the automatic heat press or in a cloud server, and is configured so that the user can access and control it through an external terminal.

[0016] Furthermore, the material type includes the type of material, and the one or more characteristics include the thickness and custom parameters of the material.

[0017] Furthermore, when the hot pressing plate assembly is pressed downward, it includes a first control stage and a second control stage, wherein the first control stage is 50%-95% of the pressure data configured by the user; and the second control stage is 100% of the pressure data configured by the user. By controlling the pressure in stages, the hot pressing efficiency can be high and the effect can be better.

[0018] Furthermore, the bracket is configured with at least four supporting fulcrums. With the above configuration, the force between the bracket and the base can be stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The driving mechanism 3 also includes a driving speed change device 3.1, the upper end of the screw rod is drivingly connected to the output end of the driving speed change device 3.1, and the middle part of the hot pressing plate assembly 2 is fixedly connected to the nut of the screw rod nut pair R.

[0031] The pressure detection element 5 may be a pressure sensor.

[0032] In one embodiment, a cushion 4' is disposed on the upper side of the bracket 4, and the cushion 4' is a flexible structure as a whole. An implementation scheme of the cushion 4' includes a fabric surface layer and a flexible support lining, and of course, the flexible support lining may include a flexible layer (such as sponge) and a heat-emitting layer (such as tin foil).

[0033] In one embodiment, a metal frame 4.2 is disposed at the lower side of the bracket 4, and the supporting fulcrum 4.1 is arranged on the metal frame 4.2.

[0034] Compared with the prior art, the control module e of the utility model can accurately adjust the pressure of the detection bracket 4 through the pressure detection element 5. When the pressure detection element 5 detects that the pressure exceeds the pressure configured by the user, the control module controls the driving mechanism to increase the pressure to match the pressure configured by the user. When the pressure detection element 5 detects that the pressure is less than the pressure configured by the user, the control module controls the driving mechanism to increase the output drive to match the pressure configured by the user.

[0035] The pressure detection element 5 and the speed change device 3.1 cooperate to accurately and quickly control the pressure of the hot pressing plate assembly 2, thereby improving the thermal transfer quality and user experience.

[0036] When the hot pressing plate assembly 2 is pressed downward, it includes a first control stage and a second control stage. The first control stage is a pressure of 50%-95% of the pressure data configured by the user; the second control stage is a pressure of 100% of the pressure data configured by the user.

[0038] The pressure is controlled in stages, with the first control stage being the ordinary control stage and the second control stage being the precise control stage, so that the hot pressing efficiency is high and the effect is better. In addition, in other embodiments, the pressing speed in the first control stage can be configured to be greater than the pressing speed in the second control stage, because the stroke in the first control stage is large, increasing the pressing speed can improve the work efficiency, and reducing the pressing speed in the second control stage can ensure a better effect of the hot pressing. It should be noted that the first control stage can include multiple pressure stages to control the final pressure to reach 50%-95%.

[0042] The material type includes the type of material, and the one or more properties include the thickness and custom parameters of the material.

[0043] The above-mentioned pressure calibration refers to different pressures corresponding to different types of materials. When one of the materials and / or characteristics is selected or input through the user control e1, the control module calls the relevant pressure parameters to control the output of the driving mechanism 3, thereby adjusting the downward pressure of the hot pressing plate assembly 2.

[0044] In one embodiment, the device storage module is preset with commonly used material types, characteristics and preset pressures. Of course, the user can customize the above material types, characteristics and related pressures.

[0045] It should be noted that the device storage module preset parameters and the specific implementation technical means selected through the user control e1 are existing, such as the solution disclosed in CN105189058A.

[0048] In one embodiment, the user control e1 is a touch-sensitive control configured on the automatic heat press, such as a control on a touch screen.

[0049] The hot press structure of this patent can be implemented by referring to the contents disclosed in the inventor's prior applications CN115195281A and 202323545216X.

[0051] Regarding the calculation of pressure data, one solution is that the control module e calculates an average value based on the detection data of all pressure detection elements 5 .

[0052] In other examples, the control module e determines the maximum value of the detection data of all the pressure detection elements 5 .

[0053] In other examples, the control module determines the lowest value of the detection data of all the pressure detection elements 5 .
