Description

Technical Field

[0001] This utility model relates to the field of coating machines, and in particular to a positioning fixture for interior wall panels of a drum coating machine. Background Technology

[0002] A drum coating machine, also known as a drum glue applicator, is a mechanical device that uses a rotating drum structure to achieve uniform glue or coating. It is widely used in industries such as papermaking, packaging, printing, and wood processing. Its core feature is that the rotational motion of the drum uniformly transfers adhesives, coatings, or other media to the substrate surface, offering advantages such as high efficiency, continuous operation, and uniform coating. The drum surface of the drum coater absorbs the adhesive or coating, and pressure is used to uniformly transfer the medium to the substrate surface. The coating thickness can be precisely controlled by adjusting the gap between the drum and the substrate, the drum rotation speed, or the glue supply. Drum coating machines are widely used in the paper industry for surface sizing and coating of paper, improving its strength, gloss, and printability; in the packaging industry for applying adhesives or protective coatings to materials such as films and aluminum foil, used in the production of composite packaging materials; in the printing industry for applying varnishes, matte coatings, etc., to printed materials, enhancing their visual appeal and durability; in wood processing for applying adhesives to the surface of wood panels and plywood, used in board lamination or veneer processes; and in the electronics industry for applying conductive adhesives or insulating coatings to substrates such as circuit boards and flexible circuits.

[0003] Currently, both drum-type and roller-type glue applicators on the market require the substrate to be glued to be fed into the glue applicator head. This means that the substrate, such as interior wall panels, needs to be manually fed into the glue applicator before the glue is applied. However, manually pushing the interior wall panels makes them prone to shaking, affecting the quality of the glue application. Furthermore, manual pushing requires workers to be in constant contact with the interior wall panels, increasing the workload of the workers. Utility Model Content

The positioning fixture for the inner wall panel of the drum coating machine includes two sets of positioning units, which are distributed left and right. The positioning units are used to position the inner wall panel when the drum coating machine is working.

[0053] The fixed transmission unit includes an upper positioning shaft 1 and a lower positioning shaft 2, which are symmetrically distributed vertically.

[0054] The two sets of fixed transmission units are respectively connected to the two ends of the adaptation component 6 and the bottom end of the adaptation component 6 is connected to the movable base 7. The adaptation component 6 is used to adjust the height of the fixed transmission unit.

[0055] In this technical solution, two sets of upper positioning shafts 1 and lower positioning shafts 2 can position and transport the inner wall panel, so that the inner wall panel can be sent into the drum coating machine for coating operation. During the coating process, under the limit of the fixed transmission unit, the inner wall panel will not shake randomly, which increases the stability of the inner wall panel during coating and thus increases the quality of inner wall panel coating.

[0056] The adjustable distance component 3 includes a bidirectional stud 31, the end face of which is rotatably connected to the fixed frame 4;

[0057] The surface of the bidirectional stud 31 is threaded with two symmetrically distributed adjusting plates 32. One side of each adjusting plate 32 is rotatably connected to one end of the upper positioning shaft 1 and one end of the lower positioning shaft 2, respectively.

[0058] In this technical solution, the distance between the upper positioning shaft 1 and the lower positioning shaft 2 can be adjusted using the adjusting component 3.

The anti-deviation blocks 33 are slidably connected to the inner side of the fixing frame 4 through the track grooves.

[0060] In this technical solution, the movement trajectory of the adjusting plate 32 can be limited by the anti-deviation block 33 and the fixing frame 4.

[0061] In use, the drive transmission component 5 drives the bidirectional stud 31 to rotate, which in turn drives the adjusting plates 32 on both sides to move towards or away from each other, and at this time, the anti-deviation block 33 can move in the same direction.

[0062] When the adjustment plates 32 on both sides move, they can drive the corresponding upper positioning shaft 1 and lower positioning shaft 2 to move in the same direction, so that the upper positioning shaft 1 and lower positioning shaft 2 can move towards each other or away from each other, and the distance between the upper positioning shaft 1 and lower positioning shaft 2 can be adjusted, so that the upper positioning shaft 1 and lower positioning shaft 2 can position and transport inner wall panels of different thicknesses.

[0064] The drive assembly 5 includes a fixed housing 51, and a plurality of connecting strips 52 are connected to the top of the fixed housing 51. The top of the connecting strips 52 is connected to the bottom of the fixed frame 4.

[0065] A bidirectional drive source 53 is connected to the inner cavity of the fixed housing 51. Both output ends of the bidirectional drive source 53 are connected to a drive shaft 54. The end of the drive shaft 54 ​​away from the bidirectional drive source 53 is connected to a drive part 55. The top of the drive part 55 is connected to the bottom end of the bidirectional stud 31.

[0068] In this technical solution, when the bidirectional stud 31 rotates, it can drive the adjusting plates 32 on both sides to move simultaneously towards or away from each other.

[0069] The transmission unit 55 consists of two meshing bevel gears, one of which is connected to one end of the transmission shaft 54, and the other bevel gear is connected to the bottom end of the bidirectional stud 31.

[0070] In this technical solution, the bidirectional stud 31 and the drive shaft 54 ​​are connected by the transmission part 55.

[0071] The inner wall of the fixed outer shell 51 is connected to two symmetrically distributed reinforcing plates 56. The reinforcing plates 56 are provided with mounting holes, and the surface of the drive shaft 54 ​​is rotatably connected to the reinforcing plates 56 through the mounting holes.

[0072] In this technical solution, the reinforcing plate 56 can be used to support the transmission shaft 54, making the transmission shaft 54 ​​more stable when rotating.

[0073] In use, the bidirectional drive source 53 can drive the transmission shaft 54 ​​to rotate, which in turn drives the transmission part 55 to rotate, and in turn drives the bidirectional stud 31 to rotate, providing rotational power for the bidirectional stud 31.

[0074] The adaptation component 6 includes a support frame 61, and a lifting plate 62 is provided on the inner side of the support frame 61. One side of the lifting plate 62 is connected to the fixed frame 4.

[0075] The bottom of the lifting plate 62 is connected to a lifting power source 63, and the bottom of the lifting power source 63 is connected to the inner wall of the bottom surface of the support frame 61.

[0076] In this technical solution, the height of the fixed transmission unit can be adjusted using the adaptive component 6.

[0077] The inner wall of the support frame 61 is connected to a plurality of anti-deviation rails 64, and the surface of the anti-deviation rails 64 is slidably connected to the lifting plate 62.

[0078] In this technical solution, the movement trajectory of the lifting plate 62 can be limited by the anti-deviation rail 64.

[0079] In use, based on the height of the drum filler's feed inlet, the lifting power source 63 can drive the lifting plate 62 to move vertically along the anti-deviation track 64, which in turn can drive the fixed transmission unit to move in the same direction. This allows the height of the upper positioning shaft 1 and the lower positioning shaft 2 to be adjusted so that the inner wall panel can be adjusted to the height of the drum filler's feed inlet, making it easier to feed the inner wall panel into the drum filler from the feed inlet.
