Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A pressing and adjusting structure for a coating machine includes a side plate 1, a support plate 2 mounted on the outer side of the side plate 1, a bearing roller 3 rotatably connected to the outer wall of the side plate 1, a lifting roller 4 rotatably connected to the outer wall of the side plate 1, a bearing shaft 5 mounted on the outer wall of the side plate 1, a pressing roller 6 rotatably connected to the outer wall of the bearing shaft 5, a moving groove 7 formed on the outer wall of the side plate 1, a slide rod 8 fixedly mounted on the inner wall of the moving groove 7, a moving plate 9 movably sleeved on the outer wall of the slide rod 8, a drive spring 10 movably sleeved on the outer wall of the slide rod 8, a lower screw 11 fixedly mounted on the outer wall of the moving plate 9, an upper screw 12 mounted on the outer wall of the moving plate 9, a drive cylinder 13 threadedly connected to the outer wall of the lower screw 11, an mounting plate 14 fixedly mounted on the outer wall of the bearing shaft 5, a tension gauge 15 mounted on the outer wall of the support plate 2, and a coated finished product 16 movably sleeved on the outer wall of the bearing roller 3.

[0022] By using the movable groove 7 opened on the outer wall of the side plate 1 and the support plate 2, and the bearing shaft 5 movably sleeved on the outer wall of the movable groove 7, the driving spring 10 can apply an upward or downward thrust to the bearing shaft 5, so that the outer walls of the upper and lower bearing shafts 5 move closer to each other, thereby increasing the pressure applied by the outer walls of the two side extrusion rollers 6 to the coated product 16, thus pressing the coated product 16.

[0023] In a preferred embodiment, the two ends of the outer wall of the drive spring 10 are connected to the outer walls of the moving plate 9 and the bearing shaft 5, respectively, and the rest length of the drive spring 10 when it is not under force is greater than half the length of the outer wall of the slide bar 8.

[0024] By providing a drive spring 10 on the outer wall of the slide bar 8, when the two ends of the outer wall of the drive spring 10 contact the outer walls of the moving plate 9 and the bearing shaft 5 respectively, the drive spring 10 will be in a compressed state, thereby enabling the drive spring 10 to provide power to the bearing shaft 5, so that the upper and lower bearing shafts 5 can move closer to each other, thereby achieving the squeezing of the coated finished product 16.

[0025] In a preferred embodiment, the inner cavity of the bearing shaft 5 is provided with a movable hole, and the inner wall diameter of the movable hole matches the outer wall diameter of the slide rod 8.

[0026] By means of the bearing shaft 5 movably sleeved on the outer wall of the slide bar 8, the driving spring 10 is compressed to drive the bearing shaft 5, so that the bearing shaft 5 can move up and down on the outer wall of the slide bar 8, better pressing the outer wall of the coated product 16. By adjusting the position of the moving plate 9, the stroke of the driving spring 10 is changed, thereby increasing or decreasing the elastic force it exerts on the outer wall of the bearing shaft 5.

[0027] In a preferred embodiment, the outer wall of the drive cylinder 13 at the end away from the upper screw 12 meshes with the outer wall of the lower screw 11, and the threads on the outer wall of the upper screw 12 and the outer wall of the lower screw 11 are in opposite directions.

[0028] By using the drive cylinder 13 provided on the outer walls of the lower screw 11 and the upper screw 12, when the drive cylinder 13 is rotated, the lower screw 11 and the upper screw 12 can be moved closer to each other or further away from each other under the action of the drive cylinder 13, thereby adjusting the distance between the outer walls of the lower screw 11 and the upper screw 12, thereby compressing or extending the stroke of the drive spring 10 and changing the magnitude of the elastic force it exerts on the outer wall of the bearing shaft 5.

[0029] In a preferred embodiment, there are two drive cylinders 13, and the two drive cylinders 13 are respectively installed on the outer wall of the upper screw 12 on both sides.

[0030] By providing a drive cylinder 13, an upper screw 12, and a lower screw 11 on the outer walls of both the side plate 1 and the support plate 2, the distance between the lower screw 11 and the upper screw 12 can be adjusted by rotating the drive cylinder 13, so that the lower screw 11 and the upper screw 12 move closer to each other, thereby compressing the drive spring 10. The drive spring 10 can provide greater elastic force, thus better achieving the pressing and fixing of the coated finished product 16.

[0031] In a preferred embodiment, an elastic rope is installed on the outer wall of the mounting plate 14, and the outer wall of the end of the elastic rope away from the mounting plate 14 is connected to the outer wall of the tension gauge 15.

[0032] By using the mounting plate 14 installed on the outer wall of the bearing shaft 5 and the elastic rope installed on the outer wall of the mounting plate 14, when the bearing shaft 5 moves upward under the action of the drive spring 10, the tension gauge 15 will be pulled by the elastic rope. At this time, the tension generated by the movement of the bearing shaft 5 can be measured under the action of the tension gauge 15. At this time, the pressure applied to the bearing shaft 5 can be adjusted according to the actual production needs. By adjusting the position of the moving plate 9, the pressure acting on the outer wall of the coated finished product 16 can be appropriately changed.

[0033] Working principle: During use, the coated product 16 passes through the outer walls of the bearing roller 3, the lifting roller 4, and the bearing shaft 5. Pressure is applied to the outer wall of the extrusion roller 6 by the bearing shafts 5 on both sides, thus pressing the outer wall of the extrusion roller 6. By rotating the drive cylinder 13, the distance between the outer walls of the lower screw 11 and the upper screw 12 is adjusted, compressing the stroke of the drive spring 10 under the action of the moving plate 9. This increases the elastic force of the drive spring 10 acting on the outer wall of the bearing shaft 5, thereby better compressing the coated product 16. When clamping and pressing different coated products 16, the drive cylinder 13 is rotated according to the pressure they can withstand, causing the lower screw 11 and the upper screw 12 to move closer or further apart. Adjustments are made based on the reading of the tension gauge 15 to better press the coated product 16.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
