For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] As shown in the accompanying drawings, the utility model includes a frame 20, a conveyor 21 is provided below the frame 20, and a plate centering device and a glue spraying assembly are provided on the frame 20 above the conveyor 21.

[0024] The plate centering device includes a pair of transverse centering plates 23 and a pair of longitudinal centering plates 24 that are symmetrically arranged. The frame 20 is provided with a transverse centering plate driving cylinder 25 for driving the transverse centering plates 23 to swing left and right, and a translation cylinder 26 for driving the longitudinal centering plates 24 to move horizontally.

[0025] The glue spraying assembly includes a transverse translation slide 28 and a glue spraying box 29 installed on the transverse translation slide 28. The bottom of the glue spraying box 29 is an opening, and a group of glue spraying heads are provided in the bottom opening.

[0026] The plate is moved to the designated position by the conveyor 21 and stops. A pair of transverse centering plates 23 and a pair of longitudinal centering plates 24 clamp the sides of the plate from all sides to center the plate. In this case, the transverse centering plates 23 and the longitudinal centering plates 24 are both L-shaped structures. While centering the plate, the transverse centering plates 23 and the longitudinal centering plates 24 are surrounded by the plate, effectively preventing glue mist from escaping from all sides of the plate to the equipment when spraying glue.

[0027] In this case, the width of conveyor 21 is smaller than the width of the sheet material, and the length of glue spray box 29 is the same as the sheet material. A set of glue spray heads are arranged in sequence along the length of glue spray box 29. The glue barrel can be mounted on the top of frame 20. The glue spray heads are connected to the glue barrel via a high-pressure hose. During glue spraying, the horizontal translation slide 28 is activated, moving glue spray box 29 at a constant speed along the length of the sheet material. During this movement, the glue spray heads evenly spray glue onto the surface of the sheet material. During glue spraying, a gap of 15-20 mm is provided between the bottom opening of glue spray box 29 and the sheet material to reduce the escape of glue mist.

[0028] Preferably, the conveyor 21 is a belt conveyor or a synchronous belt conveyor; the conveyor 21 is a belt conveyor or a synchronous belt conveyor.

[0029] Specifically, the transverse center plate 23 is hinged to the frame 20 through a pin shaft, and both ends of the transverse center plate driving cylinder 25 are movably connected to the transverse center plate 23 and the frame 20 respectively.

[0030] Furthermore, a pair of guide rods 32 are provided on both sides of the frame 20, and the longitudinal centering plate 24 is movably mounted on the guide rods 32. Each longitudinal centering plate 24 corresponds to two translation cylinders 26. The translation cylinders 26 are fixed to the frame 20 and drive the longitudinal centering plate 24 to move horizontally.

[0031] The longitudinal centering plate 24 is provided with a guide sleeve that cooperates with the guide rod 32. Since the longitudinal centering plate 24 corresponds to the length direction of the plate, the length of the longitudinal centering plate 24 is longer. The longitudinal centering plate 24 is synchronously driven by two translation cylinders 26 to move horizontally, making its movement stable.

[0032] Preferably, the lateral translation slide 28 is an electric slide.

[0033] Furthermore, a plate positioning assembly 35 and a plate lifting assembly are respectively provided on the frame 20 on both sides of the conveyor 21. The plate positioning assembly 35 includes a positioning plate 36 and a positioning plate driving cylinder 37. The positioning plate 36 is hinged to the frame 20 via a pin, and the two ends of the positioning plate driving cylinder 37 are movably connected to the positioning plate 36 and the frame 20 respectively.

[0034] The plate lifting assembly includes a lifting roller 38 and a pair of lifting cylinders 39. The pair of lifting cylinders 39 are respectively fixed to the frame 20. The two ends of the lifting roller 38 are respectively mounted on the piston rods of the pair of lifting cylinders 39 through bearings.

[0035] When the plate enters the glue spraying area, one end of the positioning plate 36 extends upward to block the plate and locate the plate's moving position. Then the positioning plate 36 retracts downward to under the plate, and the plate lifting assembly starts, and the plate is partially lifted up by the lifting rollers 38 on both sides. The plate can move left and right on the two lifting rollers 38. At this time, the plate centering device is started again to clamp and center the plate on all sides.

[0036] Furthermore, a demister barrel 40 is provided on the top of the frame 20, an induced draft fan 41 is provided on the top of the demister barrel 40, a sedimentation area is provided at the bottom of the demister barrel 40, a spray pipe 42 connected to the sedimentation area is provided at the upper part of the demister barrel 40, air guide grooves 43 are provided on the top of the transverse center plate 23 and the longitudinal center plate 24, and air inlets are provided on the demister barrel 40, respectively connected to each air guide groove 43.

[0037] The horizontal parts of the transverse center plate 23 and the longitudinal center plate 24 are hollow structures, and a group of air inlet holes are arranged on the air guide groove 43. After the induced draft fan 41 is turned on, the air inlet holes of the transverse center plate 23 and the longitudinal center plate 24 are in a negative pressure state. The glue mist escaping from all sides during the glue spraying process can enter the demisting barrel 40 through the air inlet holes. The spray pipe 42 is connected to the sedimentation area through a pump. A plurality of spray heads are provided on the spray pipe 42 for forming a water curtain in the demisting barrel 40. The glue mist enters the demisting barrel 40 and adheres to the water for purification, thereby further preventing the glue mist from escaping.
