[0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. It coats the rolled substrate with a layer of glue, coating or ink with specific functions, and then rewinds it after drying. It adopts a special multi-functional coating head, which can realize various forms of surface coating treatment. The rewinding and unwinding of the coating machine are equipped with full-speed automatic film splicing mechanism, and the PLC program can achieve tension closed-loop automatic control operation;

[0003] However, the coating equipment in the prior art is still prone to the following situations during operation:

[0004] Most of them use multiple sets of rollers to drive the substrate, which is not only easy to cause the substrate to deviate during the transmission process, but also difficult to achieve the effect of flipping the surface, which is easy to affect the double-sided coating efficiency of the substrate;

[0005] Moreover, some coating devices with a flipping structure are difficult to adapt and adjust when flipping the substrate due to its limited structure. As a result, the tension of the substrate cannot be adjusted, causing the substrate to become loose and sticky or tight and torn, which greatly affects the flipping and coating efficiency of the substrate.

[0006] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention cooperates with a movable frame, a fixed frame, a transposition plate, a storage plate and an anti-slip mechanism, and a cylinder drives the connecting plate and the vertical rod to sink, forcing the two corresponding groups of inclined plates to rotate, pulling the two groups of slide plates to approach each other, and the two groups of resistance rods to approach each other until the distance between the two is adapted to the width of the substrate, so as to facilitate the correction and straightening of the substrate;

[0020] The present invention is also assisted by the setting of the turning mechanism. The second motor drives the vertical plate to rotate counterclockwise, and uses the inner groove to pull the two groups of round shafts and the transposition plate to move respectively. The upper and lower groups of transposition plates drive the corresponding coiling rollers to move in the opposite direction. The two groups of coiling rollers are in opposite diagonal lines. The coating surface of the substrate is turned upward to replace the uncoated surface of the substrate, so as to realize the rapid turning over and double-sided coating of the substrate.

[0021] Then, by using the cooperation of the turning mechanism, the shifting plate and the winding roller, the winding teeth move in a straight line inside the transverse groove 1. The winding teeth first mesh with the tooth grooves on the inner wall of the bottom of the transverse groove 1, forcing the winding teeth and the winding roller at the top to rotate counterclockwise and wind up the loose substrate in turn, keeping the turned over substrate straight and tight. When the winding teeth pass the middle position of the transverse groove 1, the winding teeth contact the tooth grooves on the inner wall of the top of the transverse groove 1, forcing the winding teeth and the winding roller to rotate clockwise, and the auxiliary wound substrate is gradually unwound to prevent the substrate from being too tight and causing breakage and tearing. When the structure is turned over, the tension of the substrate is continuously adjusted to reduce the looseness, sticking or tightness and tearing of the substrate, thereby further improving the turning efficiency of the substrate.

[0037] Example 2: Please refer to Figure 5 - Figure 6 As shown, the anti-slip mechanism 5 includes a concave vertical frame 51, which is fixedly mounted on the bottom surface of the top plate 404 and located on one side of the top surface of the storage plate 403, and a second transverse groove 52 is provided on the bottom inner wall of the concave vertical frame 51, and a slide plate 53 is slidably connected to the bottom inner wall of the concave vertical frame 51 at the front and rear positions of the top of the second transverse groove 52, and a slide cylinder 54 is fixedly mounted on one side of the bottom end of each group of slide plates 53, and the bottom of the slide cylinder 54 extends to the inside of the second transverse groove 52 and is penetrated and connected with a blocking rod 55, and the bottom of the blocking rod 55 extends to the inside of the corresponding limiting groove 408;

[0038] A long groove 56 is provided on the inner wall of one side of the second transverse groove 52, and an inclined groove 57 is provided at the front and rear of the long groove 56, and the two groups of inclined grooves 57 are mirror-symmetrical with respect to the central axis of the long groove 56. A round shaft 58 is provided at the middle section of one side of the two groups of blocking rods 55, and the round shaft 58 is slidably connected to the front and rear ends of the long groove 56. Vertical grooves 59 are provided on the front and rear end surfaces of the concave vertical frame 51, and inclined plates 510 are hinged inside the two groups of vertical grooves 59, and the bottom of the inclined plates 510 extends to the inside of the concave vertical frame 51 and is hinged to the end of the slide plate 53.

[0039] A second inclined groove 511 is provided on one side of the inclined plate 510, and a connecting rod 512 is movably connected between the front and rear groups of inclined plates 510, and sliding shafts 513 are fixedly installed on one side of the connecting rod 512 at the front and rear ends. The two groups of sliding shafts 513 are respectively slidably connected in the corresponding second inclined groove 511, and a connecting plate 514 is fixedly installed at the center between the left and right groups of connecting rods 512. A second cylinder 515 is arranged at the top center of the connecting plate 514 through a push rod, and the second cylinder 515 is arranged at the center of the bottom surface of the top plate 404.

[0040] The substrate laid flat on the surface of the storage plate 403 is limited by the anti-slip mechanism 5, and the bottom ends of the blocking rods 55 are respectively inserted into the limiting grooves 408. The two adjacent blocking rods 55 are respectively used to limit the front and back of the substrate. The spacing between the two groups of blocking rods 55 is the width of the substrate. By starting the second cylinder 515, the push rod is used to push the connecting plate 514 and the two groups of connecting rods 512 to sink downward, and the sliding shafts 513 at the front and rear ends of each group of connecting rods 512 move downward along the corresponding inclined grooves 511, forcing the two groups of inclined plates 510 corresponding to the front and rear to rotate, and pulling the two groups of slide plates 53 to approach each other, and the bottom ends of the two groups of blocking rods 55 move along the limiting grooves 408, and the front and rear groups of blocking rods 55 approach each other until the distance between them is adapted to the width of the substrate, so as to facilitate the correction and straightening of the substrate.

[0041] After the single-side coating of the substrate is completed, the second cylinder 515 is started again, and the connecting plate 514 is used to pull the two groups of connecting plates 514 to move upward, and the sliding shaft 513 slides upward along the inside of the second inclined groove 511, thereby, the two groups of inclined plates 510 corresponding to the front and rear rotate in the opposite direction, and pull the two groups of slide plates 53 away from each other, and the blocking rod 55 moves synchronously with the slide plate 53, and the round shaft 2 58 slides from the long groove 1 56 to the inside of the inclined groove 1 57, and the blocking rod 55 is lifted upward and inserted into the inside of the slide cylinder 54, and the bottom end of the blocking rod 55 is away from the inside of the limiting groove 408, and the edge of the substrate is lost, so that the substrate can be easily separated from the surface of the storage plate 403;

[0042] This structure can not only make limited adjustments according to the width of the substrate during the coating process and reduce the deviation of the substrate during the coating and flipping process, but also realize the automatic retraction of the blocking rod 55 after the coating is completed and before flipping to avoid obstruction of the substrate flipping operation.

[0043] Embodiment 3: Before flipping, the anti-slip mechanism 5 is first separated from the storage plate 403 and the substrate, and then the cylinder 1 402 is started, which uses the push rod to push the slide bar 401 and the movable frame 4 to move forward, and the ends of the slide bar 401 respectively move forward inside the slide frame 2 until the substrate is detached from the surface of the storage plate 403, thereby reducing the obstruction to the substrate when flipping;

[0044] See also Figure 3 , Figure 4 and Figure 7As shown, two groups of transposition plates 302 are arranged diagonally, and a round shaft 306 is fixedly installed on the rear end surfaces of the two groups of transposition plates 302 and near the opposite ends. A transverse groove 307 is arranged on the inner wall of the rear end of the fixed frame 3 at the upper end, and a plurality of groups of tooth grooves 308 are evenly arranged on one half of the inner wall at the bottom of the transverse groove 307 and one half of the other side of the inner wall at the top. The rolling teeth 305 extend to one end of the interior of the transverse groove 307, and a flip assembly 6 is arranged on the rear ends of the upper and lower groups of transposition plates 302;

[0045] The flip assembly 6 includes a second motor 61, which is arranged at the center of the inner wall of the rear end of the fixed frame 3, and a vertical plate 62 is fixedly installed at the output end of the second motor 61, and the upper and lower ends of the vertical plate 62 are extended to the inner parts of the corresponding upper and lower empty slots 301, and the inner parts of the vertical plate 62 are provided with inner slots 63 at the upper and lower ends, and the two sets of inner slots 63 are respectively sleeved on the outer parts of the corresponding round shaft 1 306;

[0046] When flipping, the second motor 61 is started, which drives the vertical plate 62 to rotate counterclockwise, and uses the inner groove 63 to pull the two sets of round shafts 306 and the transposition plate 302 to move respectively, and the upper and lower sets of transposition plates 302 drive the corresponding winding rollers 303 to move in the opposite direction, and the two sets of winding rollers 303 are in opposite diagonals, thereby, the coating surface of the substrate is flipped upward to replace the uncoated surface of the substrate, so as to achieve rapid substrate flipping and double-sided coating;

[0047] After flipping, the cylinder 402 is used again to pull the slide bar 401 and the movable frame 4 to move backward, and the flipped substrate is moved to the surface of the storage plate 403 again, and the above steps can be repeated again to achieve coating on the reverse side of the substrate.

[0048] It is worth noting that during the substrate flipping process, the two sets of winding rollers 303 move and the straight-line distance between them becomes shorter. Therefore, the originally stretched substrate is very likely to become loose due to the close position of the two sets of winding rollers 303, which in turn causes the coating surface of the substrate to overlap and stick, thus affecting the coating effect.

[0049] Therefore, when the structure is in operation, the rolling teeth 305 move synchronously with the winding roller 303 and move in a straight line along the inside of the transverse groove 307. The rolling teeth 305 first mesh with the tooth grooves 308 on the inner wall at the bottom of the transverse groove 307, forcing the rolling teeth 305 and the winding roller 303 at the top to rotate counterclockwise and reel in the loose substrate in turn, keeping the flipped substrate straight and tight. When the rolling teeth 305 pass the middle position of the transverse groove 307, the rolling teeth 305 no longer contact the tooth grooves 308 at the bottom of the transverse groove 307, but contact the tooth grooves 308 on the inner wall at the top of the transverse groove 307, forcing the rolling teeth 305 and the winding roller 303 to rotate clockwise, and the auxiliary rolled substrate is gradually unwound to prevent the substrate from being too tight and causing breakage and tearing. When the structure is turned over, the tension of the substrate is continuously adjusted to reduce the looseness, sticking or tightness and tearing of the substrate, thereby further improving the flipping efficiency of the substrate.

[0050] When the present invention is used, the rolled substrate is firstly rolled up outside the winding roller 303 at the top, and then the starting end of the substrate is pulled to the winding roller 303 at the bottom, and the motor 1 304 is started to drive the winding roller 303 to rotate counterclockwise to roll up the substrate, and the substrate located between the two sets of winding rollers 303 is laid flat on the storage plate 403;

[0051] Secondly, the second cylinder 515 is started, which uses a push rod to push the connecting plate 514 and the two groups of connecting rods 512 to sink downward, and the sliding shafts 513 at the front and rear ends of each group of connecting rods 512 move downward along the corresponding second inclined groove 511, forcing the two corresponding groups of inclined plates 510 to rotate and pull the two groups of slide plates 53 to approach each other, while the bottom ends of the two groups of blocking rods 55 move along the inside of the limiting groove 408, and the front and rear groups of blocking rods 55 approach each other until the distance between them matches the width of the substrate, and the bottom surface of the substrate contacts the coating roller 406, and the bottom surface of the substrate is evenly coated as the substrate is rolled up;

[0052] Then, when the single-side coating of the substrate is completed, the second cylinder 515 is started again, and the connecting plate 514 is used to pull the two groups of connecting plates 514 to move upward, and the sliding shaft 513 slides upward along the inside of the second inclined groove 511, thereby, the two groups of inclined plates 510 corresponding to the front and rear rotate in the opposite direction, and pull the two groups of slide plates 53 away from each other, and the blocking rod 55 moves synchronously with the slide plate 53, and the round shaft 2 58 slides from the long groove 1 56 to the inside of the inclined groove 1 57, and the blocking rod 55 is lifted upward and inserted into the inside of the slide cylinder 54, and the bottom end of the blocking rod 55 is away from the inside of the limiting groove 408, losing the limitation on the edge of the substrate, and then the cylinder 1 402 is started again, and the push rod is used to push the slide bar 401 and the movable frame 4 to move forward, and the ends of the slide bar 401 respectively move forward inside the slide frame 2 until the substrate is detached from the surface of the storage plate 403.

[0053] Then start the motor 2 61, which drives the vertical plate 62 to rotate counterclockwise, and uses the inner groove 63 to pull the two sets of circular shafts 1 306 and the transposition plate 302 to move respectively, and the upper and lower sets of transposition plates 302 drive the corresponding winding rollers 303 to move in the opposite direction, and the two sets of winding rollers 303 are in opposite diagonals. As a result, the coated surface of the substrate is turned upward and replaced by the uncoated surface of the substrate. After the turning is completed, the cylinder 1 402 is used again to pull the slide bar 401 and the movable frame 4 to move backward, and the turned substrate moves to the surface of the storage plate 403 again, and the above steps can be repeated again to achieve coating on the reverse side of the substrate.
