[Technical Field]

[0001] The present application relates to the field of thermal transfer equipment technology, specifically to a thermal transfer device, and in particular to an improvement in a bracket. [Background technology]

[0002] Traditional thermal transfer machines generally use hydraulic or pneumatic methods, which are complicated in structure and heavy in weight. To solve these problems, some manufacturers have designed motor-driven solutions. This type of thermal transfer machine includes a body, a base, a bracket and a heating platen module. The bracket is installed on the base, and a pad is generally placed on the bracket to improve ventilation and heat pressing effect. Summary of the Invention

Positioning protrusions are provided on the upper edge of the bracket, surrounding a cushion member mounting area. The pad member is installed within the pad member mounting area and is positioned by the positioning protrusion, with the thickness of the pad member projecting beyond the upper surface of the positioning protrusion.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Referring to Figures 1 to 8, the thermal transfer device includes a main body 1, a thermal pressure plate module 2, a bracket 3, and a pad d. The main body 1 has a level upper support seat 1.1 and a lower support seat 1.2. The thermal pressure plate module H is located below the upper support seat 1.1 and is operated for vertical movement by a drive mechanism m. The bracket 3 is located above the lower support seat 1.2 and is used to provide support for the thermal transfer material. Positioning protrusions 3.1 are provided along the upper side of the bracket 3, which surround a cushion member placement area 3-d. The pad d is located within the pad placement area 3-d and is positioned by the positioning protrusions 3.1, with the thickness of the pad d extending beyond the upper surface of the positioning protrusions 3.1. The positioning protrusions 3.1 on the edge of the bracket 3 provide effective positioning for the cushion member d, preventing displacement of the cushion member d and the bracket 3. This results in a simple structure and quick operation.

[0018] The positioning protrusion 3.1 is a convex edge that surrounds the edge of the bracket 3, and this structure is strong and easy to manufacture. A control area e is provided on the front end surface of the upper support base 1.1, and control equipment devices such as keys and touch screens are installed in the control area e.

A first bearing mounting portion m411 is installed on the inner wall of the first box member m41. A second bearing mounting portion m421 and a rod assembly hole m422 passing through the middle of the second bearing mounting portion m421 are installed on the inner wall of the second box member m42. The upper end of the rod R1 passes through the upper side of the reduction gear m2 and is located below the reduction gear m2 to connect the first plane bearing m51 and the second plane bearing m52, respectively. The first plane bearing m51 is installed on the first bearing mounting portion m411, and the second plane bearing m52 is installed on the second bearing mounting portion m421. The upper end of the rod R1 employs a first flat bearing m51 and a second flat bearing m52, which are assembled with the first box part m41 and the second box part m42. The axial support characteristics of the first flat bearing m51 and the second flat bearing m52 are utilized to assemble with the first bearing mounting part m411 and the second bearing mounting part m421, thereby realizing axial positioning of the rod R1. By using a general-purpose rod R1 in this way, there is no need to process an axial positioning structure on the rod R1, which is more economical.

[0021] To maintain the concentricity of the rod R1, a radial bearing m53 is also provided below the rod mounting hole m422. The rod R1 is mounted on the radial bearing m53, which refers to a bearing that can maintain coaxiality, such as a roller bearing. To facilitate the mounting of the radial bearing m53, a third bearing mounting portion m423 that opens downward is provided below the rod mounting hole m422, and the radial bearing m53 is attached to this third bearing mounting portion m423 by screws.

In other embodiments, the positioning protrusions 3.1 may be provided in several numbers, arranged all the way around the edge of the bracket 3.

This arrangement effectively improves the structural integrity of the rail mounting protruding wall S1, more stably supports the bracket 3, and more stably transmits force.

[0025] The reinforcing rib structure t includes a reinforcing ring t0 located on the lower edge of the bracket body 3.2 and surrounding the inner wall edge 3.3 of the bracket, a first reinforcing bar t1 connecting the reinforcing ring t0 to the bracket wall edge 3.3, a second reinforcing bar t2 located horizontally inside the reinforcing ring t0, and a third reinforcing bar t3 located vertically inside the reinforcing ring t0, where the first vertical reinforcing bar S11 and the second vertical reinforcing bar S12 are connected to the second reinforcing bar t2 at corresponding positions.
