Description

Technical Field

[0001] The utility model relates to the field of quartz stone plate production equipment, in particular to an internal airbag press. Background Art

[0002] Quartz stone plates are artificial plates made by mixing quartz sand and other mixtures with resin and then placing them in a mold and pressing them with a plate press. The working principle of the plate press is that in a vacuum environment, the vibrating head is pressed down to contact the quartz stone slab, and the quartz stone slab is vibrated and compacted by vibration. The way to control the pressing down of the vibrating head is to use a hydraulic cylinder to control, which makes hard contact with the quartz stone slab. When pressing the plate, the pressing head is prone to yaw, affecting the pressing effect. Therefore, it is particularly necessary to develop an internal airbag press that can improve the yaw of the pressing head, ensure stable pressing of the plate, and have a good vibration compaction effect on quartz stone plates. Summary of the Invention

[0004] The adopted technical scheme is as follows:

[0005] An internal airbag press includes a machine base. A conveyor belt is arranged at the upper end of the machine base. A vacuum hood is arranged above the conveyor belt. A plurality of first telescopic cylinders connected to the vacuum hood are vertically arranged on the machine base. A pressing head assembly is arranged inside the vacuum hood. The pressing head assembly is slidably and sealingly connected with the vacuum hood. A plurality of second telescopic cylinders are vertically arranged on the vacuum hood. A plurality of supports are connected to the upper end of the pressing head assembly. The supports correspond to the second telescopic cylinders up and down. The pressing head assembly is provided with a plurality of airbags. The upper ends of the airbags are connected to the vacuum hood. The pressing head assembly is provided with a double-headed vibration motor.

[0006] Preferably, a plurality of guide shafts are vertically arranged on the machine base, and a plurality of guide sleeves corresponding to the guide shafts one by one are arranged on the vacuum hood.

[0007] Preferably, both the first telescopic cylinder and the second telescopic cylinder are hydraulic cylinders.

[0008] Preferably, a wire pipe rack is arranged at the upper end of the vacuum hood, and a plurality of groups of wire pipe clips are arranged on the wire pipe rack.

[0009] Preferably, the pressing head assembly includes a frame, a pressing plate is arranged at the lower end of the frame, and the double-headed vibration motor is fixedly arranged on the pressing plate.

[0010] Compared with the prior art, the beneficial effects are as follows:

[0011] When the utility model presses the plate, the first telescopic cylinder is used to drive the vacuum hood to descend and press on the machine base, the second telescopic cylinder extends to push the pressing head assembly upward, so that the pressing head assembly rises. The external vacuum pumping equipment is used to pump the air in the vacuum hood to a vacuum state. Then the double-head vibration motor is started, and the lifting of the air bag is controlled to control the pressing head assembly to press the quartz stone plate in the mold. The lifting of the air bag is combined with the vibration of the double-head vibration motor to pat the quartz stone plate. The pressing head assembly is in flexible contact with the quartz stone plate through the air bag. During the vibration process, the pressing head assembly is not prone to yaw, is easy to control, and has a good plate pressing effect. Description of the Drawings
