The casing cover member 1b includes an upper casing member 1b1 that covers the upper stand 1a1, a lower casing member 1b2 that covers the lower stand 1a2, and a side casing member 1b3 that covers the side stand 1a3. The driving mechanism m is attached to the upper stand 1a1. The hot pressure plate module H is disposed under the upper casing 1b1 and moves up and down by the driving mechanism m. The bracket 3 is supported by the lower stand 1a2 and is used to provide support for the thermal transfer article.

[0023] 1, 2, 10 and 11, the driving mechanism m includes a motor m1, a reduction gear m2, a toothed member m3 and a rod nut R, and the upper end of the rod R1 is fixedly connected to the center of the reduction gear m2. The hot pressure plate module H is disposed under the upper stand 1a1, its center is fixedly connected to the nut R2, and moves up and down by the rotational driving of the rod R1. By using the screw nut pair R to drive the hot pressure plate module H to rise and fall, the driving mechanism m is attached to the upper stand 1a1 and located in the upper casing 1b1, and the vertical direction of the rod R1 is fixed, which can reduce the volume and weight of the product and reduce costs.

[0024] By designing the main body 1 into a metal stand 1a and a casing cover member 1b, the driving unit m and the bracket 3 are connected to the metal stand 1a, the weight and working force of the driving unit m and the bracket 3 are added to the metal stand 1a, and the casing cover member 1b plays an aesthetic and protective role, and the selection space for the material of the casing cover member 1b is large, while ensuring the structural strength, the weight and volume of the main body 1 can be effectively reduced and the cost reduced. In addition, the outer casing cover 1b can be made of common outer casing industrial materials, which further increases the appearance design space of the product.

[0025] 1, 7 and 8, in one embodiment, the drive mechanism m further includes a transmission m4 mounted on the drive mounting area 1.10, a rod upper end, a reduction gear m2, and a transmission gear member mounted in the transmission m4, and the motor m1 is fixedly connected to the transmission m4. With the above structure, the volume of the entire drive mechanism m is further smaller. Since the drive gear member is a worm and the reduction gear m2 is a worm gear, the thickness of the drive mechanism m can be further reduced, and therefore the thickness of the upper holder 1.1 can be further reduced.

[0026] 10 and 11, in one embodiment, the transmission box m4 includes a first box member m41 and a second box member m42 arranged one above the other. 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 mounting 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 above and 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 in the first bearing mounting portion m411, and the second plane bearing m52 is installed in the second bearing mounting portion m421. The upper end of the rod R1 adopts 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, and which utilizes the axial support characteristics of the first flat bearing m51 and the second flat bearing m52 to assemble with the first bearing mounting part m411 and the second bearing mounting part m421, thereby realizing axial positioning of the rod R1. In this way, a universal rod R1 can be used, and there is no need to machine an axial positioning structure on the rod R1, which is more economical.

[0027] In order to maintain the concentricity of the rod R1, a radial bearing m53 is further provided at the bottom of the rod mounting hole m422. This radial bearing m53 is attached to a radial bearing m53, where radial bearing m refers to a bearing capable of maintaining concentricity such as a roller bearing. In order to facilitate the attachment of the radial bearing m53, a third bearing attachment portion m423 with an open bottom is provided at the bottom of the rod mounting hole m422, and the radial bearing m53 is attached within the third bearing attachment portion m423 and fixed at the bottom by a screw.

[0028] In one embodiment, the reduction gear m2 is made of plastic and fixed to the rod R1 by injection molding. A pin hole R10 is provided at the location where the rod R1 connects to the reduction gear m29. A pin (not shown) is installed in the pin hole R10.

[0031] In one embodiment, the side stand 1a3 includes two spaced apart side pillars 1a31, one end of each upper pillar 1a11 is connected to the upper end of the corresponding side pillar 1a31, and the lower end of each side pillar 1a31 is connected to the lower stand 1a2. This structure can be adopted to reduce the weight of the side stand 1a3, ensure the structural rigidity, and reduce the material cost.

[0032] 4 to 8, in one embodiment, the connection between one end of the upper support arm 1a11 and the upper end of the corresponding side upright 1a31 includes a tripod support connection part 1a13 and a corner connection part 1a14. The triangular support connection part 1a13 connects the lower side of one end of each upper support arm 1a11 to the inner side of the upper end of the corresponding side upright 1a31. The length of the corner connection part 1a14 matches the distance between the upper ends of the two side uprights 1a31, and both ends of the corner connection part 1a14 cover and connect the upper side of one end of each upper support arm 1a11 to the outer upper part of the corresponding side upright 1a31. In another design, two corner connection parts 1a14 are installed and arranged to cover the outer upper part of the side upright 1a31 that connects the upper side of one end of each upper support arm 1a11 to the corresponding side.

[0033] By adopting the above connecting structure, the triangular stability of the triangular support connecting member 1a13 and the corner limiting characteristics of the corner connecting member 1a14 can ensure that the connection between the upper end of the upper support arm 1a11 and the upper end of the side upright 1a31 is stable and reliable.

[0034] In one embodiment, the corner connection portion 1a14 and the corresponding side pillar 1a31 are fixed by welding, thereby ensuring the stability of the connection with the side pillar 1a31, and in order to facilitate welding between the corner connection portion 1a14 and the corresponding side pillar 1a31, the two can be pre-positioned by screws.

[0035] The corner connection 1a14 and the corresponding side upright 1a31 may be connected by screws only if the stress is met, and the product dimensions, weight, and the magnitude of the hot pressing plate module H pressure are the main considerations.

[0036] The triangular support connecting member 1a13 is preferably connected by a screw, which makes it easy to connect and remove the upper stand 1a1 and the side upright 1a31. For the stability of the connection, it is also possible to add welding assistance or to connect by welding only.

The lower stand 1a2 adopts the above structure to ensure structural strength and reduce material weight at the same time, and at the same time, the space formed under the support surface 1a20 is rationally used to provide a space position for the lower connection of the two side uprights 1a31, making the product structure more compact, and the column socket 1a23 makes the installation of the two side uprights 1a31 convenient and quick.

[0038] A lateral stopper structure is disposed below the column socket 1a23 to laterally restrict the lower side of the side pillar 1a31. Because the thickness of the support surface 1a20 is limited, the lateral stopper structure reduces the contact surface between the column socket 1a23 and the two side pillars 1a31, preventing the two side pillars 1a31 from becoming unstable laterally. Of course, the lateral stopper structure can also be installed above the column socket 1a23 without affecting the assembly. The lateral limit structure scheme is the extension wall 1a231.

[0039] In one embodiment, the lower ends of the two side pillars 1a31 and the lower end of the lower stand 1a2 are connected by welding, so that the connection between them becomes stronger. Reinforcing connectors 1a24 are arranged to reinforcingly connect the lower sides of the two side pillars 1a31 and the lower stand 1a2.
