Description

Technical Field

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

[0002] Traditional heat press machines use a single screw design for their two-stage pressing mechanism, which takes up a lot of space. Furthermore, the speed is limited when the hot platen mechanism is pressing down. Simply increasing the screw speed to increase the pressing speed of the hot platen can easily cause instability in the hot platen mechanism. Utility Model Content

[0003] In view of the above problems, this utility model proposes a two-stage pressing device for a heat press machine, which occupies little space and makes the pressing mechanism of the hot platen efficient and stable.

[0004] The technical solution of this utility model:

[0005] A two-stage pressing device for a heat press machine includes two-stage telescopic housings and a two-stage driving mechanism. The two-stage telescopic housings include an outer shell, a primary telescopic housing, and a secondary telescopic housing. The upper end of the outer shell is fixed to an upper support. The primary telescopic housing is installed inside the outer shell, and the secondary telescopic housing is installed inside the primary telescopic housing, with its lower end extending out and connected to a heat press plate assembly. The two-stage driving mechanism includes a driving screw, a sliding outer screw, a primary driving nut, and a secondary driving nut. The driving screw is installed on the upper support. The sliding outer screw is sleeved on the driving screw and connected to the driving screw via a sliding groove structure. The primary driving nut is sleeved on... The first-stage drive nut is threaded onto and connected to the drive screw, and is located above the sliding outer screw. The upper end of the sliding outer screw is rotatably connected to the first-stage drive nut. The second-stage drive nut is fitted onto the sliding outer screw and threaded onto it. The first-stage drive nut is connected to the first-stage telescopic housing, and the second-stage drive nut is connected to the second-stage telescopic housing. When the drive screw rotates, the sliding outer screw rotates with the drive screw. The first-stage drive nut drives the first-stage telescopic housing to extend and retract, and the sliding outer screw to move. The second-stage drive nut drives the second-stage telescopic housing to extend and retract, and the extension and retraction of the second-stage telescopic housing drives the hot press plate assembly to move up and down.

[0006] Further refining the above technical solution, the two-stage drive mechanism is located inside the two-stage telescopic housing; the layout is reasonable and compact.

[0007] To further refine the above technical solution, the two-stage drive mechanism uses a motor as a power source, and the motor is connected to the upper end of the drive screw.

[0008] Further refining the above technical solution, the outer shell, the first-stage telescopic shell, and the second-stage telescopic shell are all square shells; the structure is simpler, and the square shape is used to guide the telescopic movement of the first-stage telescopic shell and the second-stage telescopic shell.

[0009] To further refine the above technical solution, the upper end of the sliding external screw is sleeved on the lower end of the primary drive nut, and the lower end of the primary drive nut is equipped with a sliding external screw anti-disengagement plate, which constitutes the anti-disengagement limit of the sliding external screw.

[0010] Further refining the above technical solution, the slide structure includes two guide grooves and two guide blocks. The two guide grooves are arranged on the outer periphery of the drive screw and are symmetrical. The two guide blocks are arranged on the inner side of the sliding outer screw and are symmetrical. The two guide blocks are respectively placed in the two guide grooves and are slidably connected.

[0011] The advantages of this utility model are that it has a reasonable design, simple structure, two-stage telescopic design, and small space occupation; when the hot press plate assembly is pressed down, the hot press plate assembly moves downward at twice the speed under the cooperation of the drive screw, sliding outer screw, first-stage drive nut and second-stage drive nut, which is efficient and stable.
