Description

Technical Field

[0001] This utility model relates to heat press machines, specifically to a pressing device for a heat press machine. Background Technology

[0002] Heat transfer machines, such as automatic pressure heat transfer devices (202220400207.8), use a motor as a power source and a lead screw structure to press down the heat plate assembly. This has been improved, but some shortcomings still exist, such as poor self-locking performance and high cost. Utility Model Content

[0003] In view of the above problems, this utility model proposes a pressing device for a heat press machine, which has good self-locking performance and low cost.

[0004] The technical solution of this utility model:

[0005] A pressing device for a heat press machine includes a bracket, a rod, a gear, and a rack. The bracket is fixed to an upper support. The rod is installed inside the bracket, extends out at its lower end, and is connected to a hot press plate assembly. The gear is installed on the bracket, and the rack is installed on the rod, with the gear meshing with the rack. The pressing device also includes a worm gear / worm assembly, which is installed on the bracket, with the worm gear coaxially connected to the gear. The worm gear / worm assembly drives the gear to rotate, causing the rack to move up and down. The rod and the hot press plate assembly move up and down together with the rack.

[0006] Further refining the above technical solution, the worm gear / worm assembly uses a motor as a power source, and the motor is connected to the worm of the worm gear / worm assembly.

[0007] The above technical solution is further refined to include a clearance fit between the rod and the bracket.

[0008] Further refining the above technical solution, a number of teeth or grooves are evenly distributed on one side of the rod to form a rack; when the rod and the bracket are in clearance fit, the design of the grooves can prevent wear on the bracket during the up-and-down movement of the rod.

[0009] Further refining the above technical solution, the rod is a square rod; the square rod and the bracket are fitted with a clearance to form a guide for the up and down movement of the square rod, which requires no additional design.

[0010] Further refining the above technical solution, the side wall of the bracket has a window, and the gear meshes with the rack through the window in the side wall of the bracket; the meshing point is located inside the bracket, which effectively ensures the stability of the connection between the gear and the rack.

[0011] To further refine the above technical solution, a mounting plate is fixedly connected to the lower end of the rod, and the hot press plate assembly is fixed on the mounting plate.

[0012] The advantages of this utility model are that it has a reasonable design, simple structure, adopts a worm gear / worm assembly, and is supplemented by gear and rack design, which has good self-locking performance and low cost. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of a heat press machine.

[0014] Figure 2 This is a schematic diagram (3D) of the pressing device.

[0015] The diagram shows: upper support 1, lower pressing device 2, bracket 2-1, square rod 2-2, gear 2-3, rack 2-4, worm gear / worm assembly 2-5, mounting plate 2-6, hot press plate assembly 3, and motor 4. Detailed Implementation

[0016] like Figure 1-2 As shown, a heat press machine includes an upper support 1, a lower pressing device 2, and a hot press plate assembly 3. The lower pressing device 2 includes a bracket 2-1, a square rod 2-2, a gear 2-3, a rack 2-4, and a worm gear / worm assembly 2-5. The bracket 2-1 is fixed on the upper support 1 and has a window in its side wall. The square rod 2-2 is set inside the bracket 2-1 and is clearance-fitted with the bracket 2-1. Its lower end extends out and is fixed with a mounting plate 2-6. The hot press plate assembly 3 is fixed on the mounting plate 2-6. A number of toothed grooves are evenly distributed on one side of the square rod 2-2 to form a rack 2-4. The gear 2-3 is installed on the bracket 2-1 and meshes with the rack 2-4 through the window in the side wall of the bracket 2-1. The worm gear / worm assembly 2-7 is installed on the bracket 2-1, and its worm gear is coaxially connected with the gear 2-3. The motor 4 is installed on the upper support 1 and connected to the worm of the worm gear / worm assembly 2-5.

[0017] In use, motor 4 drives the worm of worm gear assembly 2-5 to rotate, the worm of worm gear assembly 2-5 drives gear 2-4 to rotate, rack 2-4 moves up and down, square rod 2-2 and hot press plate assembly 3 move up and down together with rack 2-4, realizing the pressing down and resetting of hot press plate assembly 3.
