Description

TECHNICAL FIELD

[0001] The utility model belongs to material pressure's machine, relate to sheet material gluing after alignment pressure equipment, more specifically, it is a kind of pressure machine that the air of air cylinder rising discharge is injected into workbench plate, make workbench plate change from negative pressure state to positive pressure state, so that sheet material can quickly separate from workbench plate.

[0002] In the pressure machine, sheet material composite is realized by the pressure of upper and lower workbench plate, usually by cylinder drive upper workbench plate up and down, so as to carry out sticking and separation with lower workbench plate, during composite operation, frequently accompanied by workbench plate conveying, turnover and brushing glue, pressure and other operations, which may cause sheet material to fall or shift in workbench plate, therefore, people also use negative pressure in workbench plate, use the adsorption of negative pressure to position sheet material in workbench plate, to avoid sheet material falling, shifting or curling during movement or operation, ensure the integrity of composite and the accuracy of position, play a key role in the composite process.

[0003] However, when sheet material composite operation is completed, because negative pressure restores normal pressure with delay, composite sheet material cannot immediately separate from upper workbench plate, which affects the next step operation: one is the time waiting for composite sheet material to completely fall off, two is that it may not completely fall off, resulting in the error of next operation, so that the product appears defect, needs to stop troubleshooting. These will affect the working efficiency of machine. SUMMARY

[0004] The utility model discloses a kind of pressure machines that the air of air cylinder movement discharge is injected into workbench plate, make workbench plate change from negative pressure state to positive pressure state instantaneously, it can quickly release negative pressure, let composite sheet material immediately fall off, so as to speed up operation speed, its work efficiency is higher, energy consumption is also lower.

[0005] Its purpose is realized by the following scheme:

[0006] A pressure machine, including upper ventilation workbench plate and lower ventilation workbench plate, negative pressure is formed at upper workbench plate by high-pressure fan through ventilation pipe, and upper ventilation workbench plate is driven up and down by cylinder, so that upper workbench plate can be stuck with lower ventilation workbench plate to carry out pressure on sheet material, wherein compressed air pipe is connected to cylinder air inlet by pneumatic electromagnetic valve, and its characteristics are that cylinder air outlet is connected with ventilation pipe by exhaust pipe and pneumatic electromagnetic valve.

[0007] In this way, when the sheet is being pressed, the high-pressure fan can generate negative pressure at the upper ventilation workbench plate; after the pressing operation is completed, when the upper workbench plate moves away from the lower workbench plate, the high-pressure fan stops working, and the pneumatic electromagnetic valve can be switched to inject air discharged from the air outlet of the cylinder into the upper ventilation workbench plate through the ventilation pipe, so that the upper ventilation workbench plate is rapidly converted from the negative pressure state to the positive pressure state, so that the pressed sheet can immediately fall off to the lower ventilation workbench plate.

[0008] The pressing machine provided by the application can rapidly convert the upper ventilation workbench plate from the negative pressure state to the positive pressure state by injecting air discharged from the cylinder into the upper workbench plate, so that the pressed sheet can rapidly fall off from the upper ventilation workbench plate without being disturbed by the negative pressure, thereby reducing operation errors and failure accidents.

[0009] The pressing machine provided by the application can rapidly convert the upper ventilation workbench plate from the negative pressure state to the positive pressure state by injecting air discharged from the cylinder into the upper workbench plate, so that the pressed sheet can rapidly fall off from the upper ventilation workbench plate without being disturbed by the negative pressure, thereby reducing operation errors and failure accidents.

[0010] The pressing machine provided by the application can rapidly convert the upper ventilation workbench plate from the negative pressure state to the positive pressure state by injecting air discharged from the cylinder into the upper workbench plate, so that the pressed sheet can rapidly fall off from the upper ventilation workbench plate without being disturbed by the negative pressure, thereby reducing operation errors and failure accidents.

[0011] Figure 1 is a schematic diagram of the specific structure of the utility model pressing machine. DETAILED DESCRIPTION

[0012] The specific embodiment of the utility model will be further described in detail below with reference to the drawings:

[0013] Referring to Figure 1 The pressing machine comprises an upper ventilation workbench plate 1 and a lower ventilation workbench plate 2, a high-pressure fan 3 forms negative pressure at the upper workbench plate 1 through a ventilation pipe 4, and a cylinder 5 drives the upper ventilation workbench plate 1 to move up and down, so that the upper workbench plate 1 can be attached to the lower workbench plate 2 to press the sheet, wherein a compressed air pipe is connected to the air inlet 51 of the cylinder through a pneumatic electromagnetic valve 7, and the air outlet 52 of the cylinder is communicated with the ventilation pipe 4 through the exhaust pipe 6 and the pneumatic electromagnetic valve 7.

[0014] In this way, when the sheet is being laminated, the high-pressure fan 3 can generate negative pressure at the upper ventilation workbench plate 1 through the ventilation pipe 4; after the sheet lamination operation is completed, when the upper ventilation workbench plate 1 moves away from the lower ventilation workbench plate 2, the high-pressure fan 3 stops working, and is switched by the pneumatic electromagnetic valve 7, so that the air discharged from the air outlet 52 of the air cylinder is sent to the upper ventilation workbench plate 1 through the ventilation pipe 4, and the negative pressure is released, so that the laminated sheet can be immediately detached to the lower ventilation workbench plate 2.
