By adjusting the focal length of the zoom lens, the position of the focal point of the laser beam in the height direction of the housing 1 can be changed. By adjusting the galvanometer, the position of the focal point of the laser beam in the length direction and the width direction of the gantry 1 can be changed.

Specifically, the first conveyance mechanism 3 includes a first motor 31 and a plurality of first rotation shafts 32.

The first motor 31 is bolted to the machine frame 1, with its shaft running in the width direction of the machine frame 1 and connected to one of the first shafts 32 by means of a coupling.

The first rotating shaft 32 is arranged along the width direction of the frame 1 and rotatably erected on the frame 1 through a bearing seat. The first rotating shafts 32 are located in the middle of the frame 1 in the width direction, the first rotating shafts 32 are uniformly arranged in the length direction of the frame 1, and each first rotating shaft 32 is sleeved with a first roller 33.

In this embodiment, each first rotating shaft 32 is keyed with a sprocket, and each sprocket is wound with a chain. When the first motor 31 drives one of the first rotating shafts 32 to rotate, the first rotating shafts 32 rotate synchronously under the driving of the chain and the chain wheel, and finally the first rollers 33 rotate synchronously.

In other embodiments of the present application, a main gear may be provided on the first shaft 32, and a plurality of sub-gears may be rotatably provided on the frame 1. The auxiliary gear is placed between two adjacent main gears, and the auxiliary gear is engaged with the two main gears simultaneously, so that each first rotating shaft 32 can rotate synchronously.

Further, the first roll 33 is composed of a roll body 331 and a roll cover 332.

The cylinder 331 is composed of a square cylinder section 3311 and a cylinder section 3312, wherein the cross section of the square cylinder section 3311 is square outside and round inside, and the square cylinder section 3311 is sleeved on the middle part of the first rotating shaft 32. The cylindrical sections 3312 are provided in pairs at both ends of the square cylindrical section 3311, and are integrally formed with the square cylindrical section 3311, and the outer diameter of the cylindrical section 3312 is larger than the maximum length of the cross section of the square cylindrical section 3311.

The outer side wall of the roller sleeve 332 is provided with an arc-shaped groove 3321 and a notch 3322, wherein the arc-shaped groove 3321 is arranged along the circumferential direction of the roller sleeve 332, and the notch 3322 is arranged along the radial line direction of the roller sleeve 332. The width of the notch 3322 is equal to the width of the square barrel 3311, and the roller shell 332 is engaged with the square barrel 3311 through the notch 3322. In addition, a screw 333 is inserted into the square tube section 3311, and the screw 333 is inserted into the slot 3322 and the square tube section 3311, and is screwed with the roller shell 332 after passing through the square tube section 3311, thereby fixing the roller shell 332 and the square tube section 3311.

When the plate material is conveyed, the worker unscrews the screw 333, removes the roller shell 332 from the square cylindrical section 3311, and supports the plate material by the cylindrical section 3312. When the pipe is conveyed, an operator clamps the roller sleeve 332 on the square barrel section 3311, screws 333 are screwed in, the pipe is supported by the roller sleeve 332, and the inner wall of the arc-shaped groove 3321 is tightly attached to the bottom end of the pipe.

The second main shaft 43 and each second auxiliary shaft 44 are sleeved with a second roller 45, when the second motor 46 is started, the second main shaft 43 and each second auxiliary shaft 44 synchronously rotate, and each second roller 45 synchronously rotates to match with the first roller 33 to convey the plates or the pipes.

Further, a second motor 46 is bolted to the frame 1, a transmission shaft 47 is rotatably mounted on the frame 1 through a bearing seat, and the second main shaft 43 and each of the second auxiliary shafts 44 are rotatably mounted on the roll-over stand 42 through a bearing seat.

The turning shaft 41 is superposed on the axis of the transmission shaft 47 and rotatably erected on the frame 1 through a bearing seat. The roll-over stand 42 is fixedly connected to the roll-over shaft 41 and thus is in a rotating fit with the frame 1. When the roll-over stand 42 rolls over around the axis of the roll-over shaft 41, the second main shaft 43, the second auxiliary shaft 44, the second roller 45 and the auxiliary bevel gear roll over along with the roll-over stand 42, but the auxiliary bevel gear is always meshed with the main bevel gear 491, so that the second motor 46 can drive the second main shaft 43 to rotate no matter the angle to which the roll-over stand 42 rolls over.

When the plates are conveyed, the piston rods of the oil cylinders are in a contracted state, the roll-over stand 42 is kept horizontal, the axes of the second main shaft 43 and each second auxiliary shaft 44 are also kept horizontal, and the top ends of the second rollers 45 are flush with the top ends of the first rollers 33. At this time, the second rollers 45 and the first rollers 33 support the lower surface of the plate material together.

When the pipe is conveyed, the operator controls the piston rod of the oil cylinder to extend out to jack the roll-over stand 42, so that the side of the roll-over stand 42, which is back to the first conveying mechanism 3, is turned upwards, and the second main shaft 43, the second auxiliary shaft 44 and the second roller 45 are also inclined accordingly. At this time, the first rollers 33 hold the bottom end of the pipe, and the second rollers 45 of the two second conveying mechanisms 4 respectively abut against the lower portions of the two sides of the pipe.

The top end of the carrier roller 5 is flush with the top end of the first roller 33, and when the plate is conveyed, the carrier roller 5 supports two sides of the plate, so that the two sides of the plate are prevented from being deformed and drooping.

Example 2

Referring to fig. 7, the difference from embodiment 1 is that the angle adjusting assembly 48 is composed of a wedge 481 and a screw 482.
