The rear end of the right driving shaft 6 is fixedly sleeved with a ball cam ring 941, and the ball cam ring 941 is meshed with the ball cam disc 94. When the ball cam ring 941 rotates, the ball cam ring 941 can drive the ball cam disc 94 to rotate.

[0036] First, pull the sealing cover 2 upward to swing open, pull the mounting frame 4 upward to swing it to drive the drive shaft 6 to swing upward to a suitable position, then put the winding roller on the right drive shaft 6, and put a roll of photosensitive dry film coated with masterbatch on the left drive shaft 6, pull the mounting frame 4 downward to swing it to a horizontal state, and then pull the head end of the photosensitive dry film to move to the right and fix it on the winding roller, twist the threaded rod 8 in reverse to drive the U-shaped frame 81 to move backward, the U-shaped frame 81 moves backward and drives the card plate 82 to move backward through the buffer spring 83, when the card plate 82 moves backward and contacts the winding roller, the card plate 82 limits the winding roller, and at the same time, the card plate 82 moves backward The movement also drives the front sliding column 96 to move backward, and the front sliding column 96 moves backward to drive the front limit frame 92 to swing to the left, and the front limit frame 92 swings to the left and drives the sliding rod 91 to move to the left, and the sliding rod 91 moves to the left and drives the rear limit frame 92 to swing to the left, and the front and rear limit frames 92 swing to the left and drive the front and rear smoothing rods 93 to swing to the left, and the front and rear smoothing rods 93 swing to the left to adapt to the size of the photosensitive dry film. When the card plate 82 stops moving backward, the U-shaped frame 81 continues to move backward to compress the buffer spring 83, stop twisting the threaded rod 8, the U-shaped frame 81 stops moving backward, and the card plate 82 also stops driving the front sliding column 9 6 moves backward, and the front and rear smoothing rods 93 stop swinging to the left. The front and rear smoothing rods 93 are just the right size of the photosensitive dry film. Then the sealing cover 2 is pulled downward to swing to seal the heating box 1, and then the heating module 3 is started. The heating module 3 emits heat to dry both sides of the photosensitive dry film at the same time. At this time, the motor 7 is started, and the motor 7 drives the right driving shaft 6 to rotate through the synchronous belt assembly. The rotation of the right driving shaft 6 drives the winding roller to rotate. The winding roller rotates to reel up the photosensitive dry film, which makes the photosensitive dry film move to the right and be fully dried. At the same time, the rotation of the right driving shaft 6 also drives the ball convex ring 941 to rotate. The ball convex ring 9 The rotation of 41 drives the ball convex disc 94 to rotate, the rotation of the ball convex disc 94 drives the spline shaft 95 to rotate through the synchronous belt assembly, the rotation of the spline shaft 95 drives the worm 99 to rotate, the rotation of the worm 99 drives the worm wheel 98 to rotate, the rotation of the worm wheel 98 drives the rotating shaft 97 to rotate, the rotation of the rotating shaft 97 drives the front and rear smoothing rods 93 to rotate through the bevel gear assembly, the front and rear smoothing rods 93 rotate to smooth the middle position of the photosensitive dry film from the outside, and the smoothed photosensitive dry film is then wound up by the winding roller, which can prevent the photosensitive dry film from becoming soft after being heated, resulting in wrinkles in the winding process, affecting the quality of the photosensitive dry film, thereby improving the quality of the photosensitive dry film.When all the photosensitive dry films have been dried, the motor 7 is turned off, the right driving shaft 6 stops driving the winding roller to rotate, the spline shaft 95 also stops driving the worm 99 to rotate, the front and rear smoothing rods 93 stop rotating, the sealing cover 2 is pulled to swing upward to open, and then the threaded rod 8 is twisted to rotate forward to drive the U-shaped frame 81 to move forward and reset. The reset of the U-shaped frame 81 first stretches the buffer spring 83 to reset, and then the U-shaped frame 81 drives the card plate 82 to move forward and reset through the buffer spring 83. The card plate 82 is reset and disengages from the winding roller, and the card plate 82 also drives the front sliding column 96 to move forward and reset, which makes the front and rear smoothing rods 93 swing right and reset, and the mounting frame 4 is pulled again to drive the driving shaft 6 to swing upward, and the winding roller of the wound photosensitive dry film is removed from the right driving shaft 6 for subsequent processing. According to the above operation, the next roll of photosensitive dry film can be dried again. Example 2

[0039] It also includes a dehumidification component, which is used to absorb and remove moisture in the hot air. The dehumidification component includes a desiccant plate 13, a column disc 131, a slotted connecting rod 132, a positioning seat 133 and a guide plate 134. Fig.10 As shown, the lower left side of the heating box 1 is embedded with a sliding connection with a desiccant plate 13, and the desiccant plate 13 is located in the cavity of the heating box 1. When the hot air contacts the desiccant plate 13, the desiccant plate 13 can absorb and remove the moisture in the hot air. The front side of the cavity of the heating box 1 is evenly spaced and rotatably connected with six guide plates 134, and each three guide plates 134 form a group. The guide plates 134 are located at the rear side of the return pipe 115. When the guide plates 134 swing left and right, the guide plates 134 can evenly diffuse the hot air on the desiccant plate 13. The top center positions of the six guide plates 134 are fixed with positioning seats 133, a slotted connecting rod 132 is slidably connected to the front side of the cavity of the heating box 1, and the groove of the slotted connecting rod 132 is slidably connected to the positioning seat 133. When the slotted connecting rod 132 moves, the slotted connecting rod 132 can drive the positioning seat 133 to swing back and forth. A straight hole is opened on the right side of the slotted connecting rod 132, and a columnar disc 131 is fixedly connected to the front end of the spline shaft 95. A column is fixedly connected to the eccentric position of the front side of the columnar disc 131, and the column of the columnar disc 131 is located in the straight hole of the slotted connecting rod 132. When the columnar disc 131 rotates, the columnar disc 131 can drive the slotted connecting rod 132 to move left and right.

[0040] When the sealing cover 2 is opened, the locking rod 101 is twisted and moved downward, and the locking rod 101 moves downward to drive the left and right locking plates 102 to swing upward. The locking plates 102 swing upward without limiting the drive shaft 6. Stop twisting the locking rod 101 and move downward, and then pull the mounting frame 4 to drive the drive shaft 6 to swing upward, and put the winding roller and a roll of photosensitive dry film on the drive shaft 6. Then pull the mounting frame 4 to drive the drive shaft 6 to swing downward and reset, twist the locking rod 101 to move upward and reset, and the locking rod 101 resets and drives the left and right locking plates 102 to swing downward and reset. The left and right locking plates 102 reset to limit the left and right drive shafts 6, and stop twisting the locking rod 101, and then proceed with subsequent operations. When the rolled-up photosensitive dry film needs to be removed, the locking plates 102 swing according to the above operation so that the drive shaft 6 is not limited, and then the mounting frame 4 is pulled to drive the drive shaft 6 to swing upward to a suitable position, and then the rolled-up photosensitive dry film can be removed. In this way, the driving shaft 6 can be prevented from swinging upward during the rotation process to affect the winding and drying of the photosensitive dry film, thereby ensuring the stability of the drying of the photosensitive dry film.

[0041] When the heating module 3 dries the photosensitive dry film, the air pump 112 is started, and the air pump 112 draws the hot air in the heating box 1 into the cavity of the heating box 1 through the return pipe 115, and the hot air is then drawn into the air inlet pipe 114, and the hot air in the air inlet pipe 114 is discharged into the three-way hose 113 through the air pump 112, and the hot air in the three-way hose 113 is discharged into the diverter pipe 111, and the hot air in the diverter pipe 111 is discharged into the guide pipe 11, and the hot air in the guide pipe 11 is sprayed on the photosensitive dry film, which further dries the photosensitive dry film. At the same time, the return pipe 115 continues to draw the hot air in the heating box 1 into the cavity of the heating box 1, and so on and so forth, which can continuously drive the hot air to circulate and flow to dry the photosensitive dry film, and accelerate the flow of the hot air. When the photosensitive dry film is dried, the air pump 112 is turned off, and the return pipe 115 stops pumping the hot air. In this way, the hot air can flow faster, thereby improving the drying effect of the photosensitive dry film.

[0042] When the motor 7 is started, the rotation of the spline shaft 95 also drives the column disk 131 to rotate, and the rotation of the column disk 131 drives the slotted connecting rod 132 to move left and right, and the left and right movement of the slotted connecting rod 132 drives the positioning seat 133 to swing left and right, and the left and right swing of the positioning seat 133 drives the guide plate 134 to swing left and right, and then when the return pipe 115 draws the hot air in the heating box 1 into the cavity of the heating box 1, the hot air contacts the guide plate 134, and the guide plate 134 swings left and right to evenly diffuse the hot air on the desiccant plate 13, and the desiccant plate 13 absorbs and removes moisture in the hot air, and the hot air after moisture is removed is drawn out by the air inlet pipe 114, which makes the guide pipe 11 spray the hot air with moisture removed on the photosensitive dry film for drying. When the motor 7 is turned off, the spline shaft 95 stops driving the cylindrical disc 131 to rotate, the cylindrical disc 131 stops driving the slotted connecting rod 132 to move left and right, and the slotted connecting rod 132 stops driving the guide plate 134 to swing left and right through the positioning seat 133. When the desiccant plate 13 needs to be replaced after a long period of use, the desiccant plate 13 is pulled to the left to break away from the contact with the heating box 1, and a new desiccant plate 13 is placed in the heating box 1. In this way, it can prevent moisture in the hot air from affecting the drying effect, thereby ensuring the drying effect of the hot air on the photosensitive dry film. Example 3

[0043] On the basis of the embodiment 1 and the embodiment 2, a buffer block 14 and a column spring 15 are also included. Fig.11 As shown, a buffer block 14 is slidably mounted on the rear side of the right driving shaft 6. The buffer block 14 contacts the winding roller and can buffer the winding roller. A column spring 15 is connected between the rear side of the buffer block 14 and the rear side of the driving shaft 6.

[0044] Also included is a diffusion rack 16, see Fig.12As shown, a diffusion frame 16 is fixedly connected to the top of the sealing cover 2 and the bottom of the heating box 1. The heating module 3 is located in the diffusion frame 16. When hot air contacts the diffusion frame 16, the diffusion frame 16 can diffuse the hot air on the photosensitive dry film.

[0045] Also includes a sealing gasket 17, see Fig.12 As shown, a sealing gasket 17 is fixedly connected to the top of the heating box 1 along the circumferential direction. The sealing gasket 17 is in contact with the sealing cover 2, so that the gap between the heating box 1 and the sealing cover 2 can be filled.

[0046] When the winding roller is sleeved on the right driving shaft 6, the winding roller contacts the buffer block 14, and the buffer block 14 buffers the winding roller due to the action of the column spring 15. In this way, the winding roller can be prevented from being violently sleeved on the driving shaft 6 to cause vibration deformation, thereby ensuring the stability of the winding roller placement.

[0047] When the heating module 3 emits hot air, the hot air contacts the diffusion rack 16, and the diffusion rack 16 makes the hot air flow more evenly distributed in the heating box 1. In this way, the hot air can contact the photosensitive dry film more evenly for drying, thereby further improving the drying effect.

[0048] When the sealing cover 2 swings upward to open, the sealing cover 2 is out of contact with the sealing gasket 17, and when the sealing cover 2 swings downward to close, the sealing cover 2 is in contact with the sealing gasket 17, and the sealing gasket 17 fills the gap between the sealing cover 2 and the heating box 1. In this way, the hot air in the heating box 1 can be prevented from overflowing through the gap between the sealing cover 2 and the heating box 1 to affect the drying temperature, thereby ensuring the drying effect of the hot air on the photosensitive dry film.
