Description

[0001] The utility model belongs to the technical field of paper suction mechanisms, and particularly relates to a suction nozzle mechanism for facilitating the separation of plate materials and paper. Background Art

[0002] PS plate is the abbreviation of pre-coated photosensitive plate, and a thin paper is provided on the surface of the PS plate. Since the plate material is thin and has a large area, it is generally arranged in the form of one PS plate material and one thin paper when stacked to protect the surface base film of the PS plate material. Before transporting the plate material, it is necessary to remove the thin paper on the plate material. At present, most on the market adopt the form of a single suction cup to suck up the thin paper, so as to facilitate the removal of the thin paper from the plate material; however, due to the thin paper being attached to the plate material, a vacuum is formed between the plate material and the paper, which is not easy to separate. When lifting the paper, there is an accidental phenomenon that the paper falls off from the suction nozzle of the single suction cup, affecting the success rate of thin paper separation.

Detailed implementation manners

[0023] The present utility model will be further described below with reference to the accompanying drawings.

[0024] A nozzle mechanism for facilitating the separation of a plate and paper, the nozzle mechanism is connected to an external air circuit, and the external air circuit is used to evacuate the suction cups of the nozzle mechanism, so as to directly adsorb on the suction cups, and the operation of the nozzle mechanism is controlled by controlling the on-off of the external air circuit.

[0025] The present nozzle mechanism includes a nozzle spacing adjustment assembly 4, a lifting assembly 6, a translation assembly 7, a nozzle mounting beam 8 and a plurality of nozzle units. The translation assembly 7 is connected to the nozzle mounting beam 8 and is used to drive the nozzle mounting beam 8 to translate. The lifting assembly 6 and the nozzle spacing adjustment assembly 4 are respectively installed on the nozzle mounting beam 8. The nozzle spacing adjustment assembly 4 is connected to the plurality of nozzle units and is used to adjust the spacing between the nozzle units. The lifting assembly 6 is connected to the nozzle mounting beam 8 and drives the nozzle mounting beam 8 to move up and down. Among them, the nozzle mounting beam 8 is a double-layer structure, the upper layer is used to install the lifting assembly 6, and the lower layer is used to install the nozzle spacing adjustment assembly 4.

[0026] Each nozzle unit includes a first suction cup assembly 1, a second suction cup assembly 2 and a nozzle fixing block 3. The first suction cup assembly 1 and the second suction cup assembly 2 are used to wrinkle the paper, facilitating air to enter between the paper and the plate, so as to facilitate the separation of the paper and the plate. The second suction cup assembly 2 is used to adsorb the paper, so as to lift the paper and realize the separation of the paper and the plate. The first suction cup assembly 1 and the second suction cup assembly 2 are respectively connected to the external air circuit, that is, the external air circuit can independently control the working conditions of the first suction cup assembly 1 and the second suction cup assembly 2.

[0027] The first suction cup assembly 1 and the second suction cup assembly 2 are slidably installed on the nozzle fixing block 3, so that the contact between the first suction cup assembly 1 and the second suction cup assembly 2 and the paper and the plate is a flexible contact, preventing the first suction cup assembly 1 and the second suction cup assembly 2 from damaging the paper and the plate during the pressing process.

[0028] The first suction cup assembly 1 includes a suction pipe 1-1 slidably mounted on the nozzle fixing block 3 and a suction cup 1-2 connected to the end of the suction pipe 1-1. Two limit nuts 1-3 are provided on the suction pipe 1-1, and the two limit nuts 1-3 are respectively located on both sides of the nozzle fixing block 3 to control the sliding amount of the suction pipe 1-1 relative to the nozzle fixing block 3. A spring 1-4 is sleeved outside the suction pipe 1-1, and both ends of the spring 1-4 are respectively abutted between the lower end of the nozzle fixing block 3 and the lower limit nut 1-3; the structure of the second suction cup assembly 2 is the same as that of the first suction cup assembly 1, and the diameter of the suction cup 1-2 of the first suction cup assembly 1 is smaller than the diameter of the suction cup of the second suction cup assembly 2, ensuring that the suction cup 1-2 on the first suction cup assembly 1 wrinkles the paper, so as to facilitate the entry of air between the paper and the board.

[0029] In this embodiment, four nozzle units are slidably mounted on the nozzle mounting beam 8 through slide rails. Among them, the nozzle units located on both sides of the nozzle mounting beam 8 are connected to the nozzle spacing adjustment assembly 4, and the spacing between the nozzle units is adjusted through the nozzle spacing adjustment assembly 4. The two nozzle units located in the middle are connected to the pulling member 5. Under normal conditions, the positions of the two nozzle units located in the middle do not change. During the movement of the nozzle units on both sides towards the nozzle units in the middle, the nozzle units on both sides will push the two nozzle units in the middle to move further towards the midpoint position of the nozzle mounting beam 8, so as to further reduce the width of the four nozzle units to meet the adsorption of smaller-sized paper.

[0030] The nozzle spacing adjustment assembly 4 includes a belt driving member and a traction block 4-1. The nozzle unit is connected to the belt driving member through the traction block 4-1, and the belt driving member drives the nozzle unit to move.

[0031] The belt driving member includes a belt driving motor 4-2, a spacing adjustment belt 4-3 and a belt pulley 4-4.

The belt driving motor 4-2 is connected to the belt pulley 4-4 to drive the belt pulley 4-4 to rotate. The nozzle units on both sides are connected to the spacing adjustment belt 4-3 through the traction block 4-1. To ensure that the nozzle units on both sides can move towards each other, the nozzle units on both sides are respectively connected to the spacing adjustment belt 4-3 located on the belt pulley 4-4.

[0032] The pulling member 5 is used to reset the nozzle units in the middle of the nozzle mechanism. The pulling member 5 includes a column 5-1, a guide wheel 5-2 and a return spring 5-3. Both ends of the return spring 5-3 are respectively connected to the column 5-1 and the nozzle unit in the middle, and the middle of the return spring 5-3 is wound around the guide wheel 5-2.

[0033] The working principle of the nozzle spacing adjustment component 4 is as follows. The belt drive motor 4-2 operates to drive the spacing adjustment belt 4-3 to translate, causing the two outer nozzle units connected to the spacing adjustment belt 4-3 to move towards each other. When the outer nozzle units interfere with the middle nozzle unit, the middle nozzle unit overcomes the force of the return spring 5-3, causing the middle nozzle unit to move towards the center of the nozzle mounting beam 8, changing the spacing between the nozzle units, so as to meet the adsorption of papers of different sizes.

[0034] The lifting component 6 includes a lifting drive member, a lifting lead screw 6-1 and a connecting frame 6-2. The lifting drive member is installed on the nozzle mounting beam 8. The lifting lead screw 6-1 is connected to the lifting drive member. The connecting frame 6-2 is installed on the nozzle mounting beam 8 in a liftable manner through a slide rail.

The drive belt 6-5 is sleeved outside the lifting pulley 6-6. The lifting motor 6-4 is connected to one of the lifting pulleys 6-6 to drive the drive belt 6-5 to operate.

[0036] The translation component 7 is connected to the connecting frame 6-2 of the lifting component 6.

[0037] The translation component 7 includes a frame beam 7-1, a gear drive member and a mounting block 7-3. The lifting component 6 is slidably installed on the frame beam 7-1 through the mounting block 7-3. A rack 7-4 is connected to one side of the mounting block 7-3. The gear drive member is connected to the rack 7-4 to drive the mounting block 7-3 to slide on the frame beam 7-1.

[0038] The gear drive member includes a gear drive motor 7-2, a rotating shaft 7-5 and gears 7-6.

[0043] (4) The first suction cup component 1 works to wrinkle the paper, the second suction cup component 2 works to adsorb the paper on the second suction cup component 2, and the lifting component 6 works to lift the paper.
