[0032] Working process: When the device is in use, the external power supply is energized. When the medium fiber board body 18 is fixed according to the width of the medium fiber board body 18, the medium fiber board body 18 is placed at the upper end of the rubber roller 17, and the hand circle 6 is rotated. The rotation of the hand circle 6 drives the two-way threaded rod 7 fixedly connected on one side to rotate, and the rotation of the two-way threaded rod 7 drives the support frame 8 connected by the outer spiral to move. The support frame 8 is slidably connected to the inner side of the movable box board 5 through a limit slider, which has the effect of limiting the movement of the support frame 8. According to the thread setting structure of the two-way threaded rod 7, when the two-way threaded rod 7 rotates, the two medium fiber board bodies can be moved. The body 18 moves in opposite directions at the same time, the support frame 8 moves to drive the upper fixed block 9 fixed at the upper end to move, and the upper fixed block 9 moves to drive the device set inside to move. When the extrusion plate 13 contacts the medium fiberboard body 18, the extrusion plate 13 pushes the square slider 12 to move, and the extrusion plate 13 squeezes the spring 14, and the spring 14 is deformed. Under the elastic force of the spring 14, the friction coefficient between the extrusion plate 13 and the outer side of the medium fiberboard body 18 is increased, and the stability of the extrusion plate 13 clamping and fixing the medium fiberboard body 18 is improved. The square slider 12 slides on the inner side of the idle column 10, and the idle column 10 is rotatably connected to the idle column 10 through the limit ring 11. The inner side of the upper fixing block 9 is convenient for the later unloading of the processed medium-density fiberboard body 18. At this time, the effect of fixing the medium-density fiberboard body 18 can be achieved. When the medium-density fiberboard body 18 needs to be coated, the motor 2 fixedly connected to one side of the coating machine case 1 is started, and the main shaft of the motor 2 rotates to drive the one-way threaded rod 3 fixedly connected to the end of the main shaft to rotate, and the one-way threaded rod 3 rotates to drive the threaded block 4 spirally connected on the outside to move, and the threaded block 4 drives the movable box plate 5 fixedly connected at the upper end to move, and the movable box plate 5 drives the column hole block 16 to move, and the inner side of the column hole block 16 is slidably connected to the outer side of the sliding stick 15, which plays a role in the movable box plate 5 moving. In order to achieve the effect of limiting the position, when the number of surfaces of the MDF body 18 to be coated is required and double-sided coating is required on the MDF body 18, the two hydraulic cylinders 21 are started and the hydraulic cylinders 21 push the coating rollers 20 to move. At this time, the lower coating roller 20 contacts the lower end of the MDF body 18, and the upper coating roller 20 contacts the upper end of the MDF body 18. The film is conveyed to the coating rollers 20 through the discharge roller 19 to achieve the effect of simultaneous double-sided coating. The heating roller 23 contacts the MDF body 18 under the elastic force of the spring telescopic rod 22 to heat the MDF body 18 and the film.
