[0002] The coating machine is mainly used for the surface coating process production of films, papers, etc., coating a roll of base material with a glue, coating or ink with a specific function, etc., and winding it up after drying. When the working material belt on the working roll is unwound, the roll needs to be changed.

The third adsorption plate 122 and the fourth adsorption plate 123 are both arranged on the second rotating seat 121. A second clearance slot 126 is arranged in the middle of the fourth adsorption plate 123, and the second clearance slot 126 is used to clear the tape cutting module. The second clearance slot 126 divides the fourth adsorption plate 123 into two independent adsorption parts.

[0051] Specifically, the first rotating seat 111 and the second rotating seat 121 are arranged in parallel, and the axial directions of the first rotating seat 111 and the second rotating seat 121 extend along the axial direction of the new coil.

[0052] In terms of quantity, the number of the glue preparation mechanisms 2 is two, and the two glue preparation mechanisms 2 respectively supply tapes to the first adsorption plate 112 and the third adsorption plate 122.

[0053] Functionally, the tape traction mechanism 3 is used to traction the tape head of the new coil to the fourth adsorption plate 123, and the waste material collection mechanism 4 is used to collect the cut tail material.

[0054] During the coil changing process, it includes a glue preparation stage, a working tape cutting stage, a new coil tape cutting stage, a tape pasting stage and a waste material collection stage.

[0055] Glue preparation stage: Referring to Figure 10, the working strip is located between the first rotating seat 111 and the second rotating seat 121. The first power member 115 drives the first rotating seat 111 to rotate to drive the second adsorption plate 113 towards the working strip, and the third power member 124 drives the second rotating seat 121 to rotate to drive the fourth adsorption plate 123 towards the working strip. At this time, the two glue preparation mechanisms 2 respectively supply tapes to the first adsorption plate 112 and the third adsorption plate 122, and the first adsorption plate 112 and the third adsorption plate 122 respectively adsorb two tapes.

[0056] Cutting the working strip stage: Refer to Figure 11 , the second power member 116 drives the first rotating seat 111 to approach the second rotating seat 121, and the fourth power member 125 drives the second rotating seat 121 to approach the first rotating seat 111, so that the second adsorption plate 113 and the fourth adsorption plate 123 respectively clamp the working strip. Then, the tape cutting module extends out of the first clearance slot 117 and cuts the working strip. Subsequently, the adsorption part on the right side of the second adsorption plate 113 adsorbs the working strip, and the second power member 116 drives the first rotating seat 111 to move away from the second rotating seat 121, and the fourth power member 125 drives the second rotating seat 121 to move away from the first rotating seat 111.

[0057] It should be noted that the left side refers to the side close to the new coil, and the right side refers to the side far from the new coil.

[0058] Cutting the strip of the new coil stage: Refer to Figure 12 and Figure 13 , the strip traction mechanism 3 tractions the strip head of the new coil to the fourth adsorption plate 123, and the fourth adsorption plate 123 adsorbs the strip of the new coil. Then, refer to Figure 14 and Figure 15 , the strip traction mechanism 3 leaves the work station. The second power member 116 drives the first rotating seat 111 to approach the second rotating seat 121, and the fourth power member 125 drives the second rotating seat 121 to approach the first rotating seat 111. The tape cutting module extends out of the first clearance slot 117 and cuts the strip of the new coil, so that the strip connecting the new coil and the cut tail stock are respectively located on two independent adsorption parts of the fourth adsorption plate 123. At this time, the left adsorption part of the fourth adsorption plate 123 releases the strip connecting the new coil, and the left adsorption part of the second adsorption plate 113 adsorbs the strip connecting the new coil, while the tail stock is adsorbed by the right adsorption part of the fourth adsorption plate 123. Then, the fourth power member 125 drives the second rotating seat 121 to move away from the first rotating seat 111, and the second power member 116 drives the first rotating seat 111 to move away from the second rotating seat 121.

[0059] Waste collection stage: Refer to Figure 16, the third power component 124 drives the second rotating seat 121 to rotate, driving the third adsorption plate 122 towards the second adsorption plate 113. At this time, the fourth adsorption plate 123 is located on the other side of the second rotating seat 121. Then, the right adsorption part of the fourth adsorption plate 123 releases the tail material, and the waste collection mechanism 4 collects the tail material.

[0060] Gluing stage: Refer to Figure 17 , the fourth power component 125 drives the second rotating seat 121 to approach the first rotating seat 111, and the second power component 116 drives the first rotating seat 111 to approach the second rotating seat 121, so that the tape on the third adsorption plate 122 is pasted on the tape of the new coil and the working tape on the second adsorption plate 113. Then, the two independent adsorption parts of the second adsorption plate 113 are released simultaneously, and the third adsorption plate 122 sucks the connected tape. Then, the second power component 116 drives the first rotating seat 111 to move away from the second rotating seat 121, and the fourth power component 125 drives the second rotating seat 121 to move away from the first rotating seat 111. Refer to Figure 18 and Figure 19 , the first power component 115 drives the first rotating seat 111 to rotate to drive the first adsorption plate 112 towards the third adsorption plate 122. Subsequently, the second power component 116 drives the first rotating seat 111 to approach the second rotating seat 121, and the fourth power component 125 drives the second rotating seat 121 to approach the first rotating seat 111, so that the tape on the first adsorption plate 112 is pasted on the tape of the new coil and the working tape on the third adsorption plate 122. Refer to Figure 20 , finally, the third adsorption plate 122 is released, the glued tape detaches from the third adsorption plate 122, the fourth power component 125 drives the second rotating seat 121 to move away from the first rotating seat 111, and the second power component 116 drives the first rotating seat 111 to move away from the second rotating seat 121. The working tape after double-sided tape connection runs normally.

[0061] Therefore, the utility model can achieve double-sided gluing, ensure the firmness of tape connection, and can collect the cut tail material, prevent the tail material from floating on the equipment or the ground, and ensure the normal operation of the equipment.

[0062] Specifically, the first power component 115 is a rotary cylinder, the second power component 116 is a telescopic cylinder. The cylinder body of the telescopic cylinder is installed on the frame 5 through the mounting seat 1161. The telescopic end of the telescopic cylinder is provided with a connecting plate 1162, the connecting plate 1162 is connected with a follower plate 1163, the rotary cylinder is arranged on the follower plate 1163, and the output shaft of the rotary cylinder is connected with the first rotating seat 111.

[0063] Furthermore, a first linear guide rail 2124 is arranged between the mounting seat 1161 and the follower plate 1163, thereby increasing the stability of the first rotating seat 111 during movement.

[0064] More specifically, the number of the first driving members 115 and the second driving members 116 is two each. Both ends of the first rotating seat 111 are respectively connected to the two first driving members 115. Thus, when the first rotating seat 111 rotates or moves, the force received is uniform, further improving the stability of the first rotating seat 111 during movement.

[0065] It should be noted that the first driving member 115 has the same structure as the third driving member 124, and the second driving member 116 has the same structure as the fourth driving member 125.

[0066] Refer to Figure 4 , in some preferred embodiments, both the first adsorption plate 112 and the second adsorption plate 113 are connected to the first rotating seat 111 through springs 118. The tape cutting module includes a first cutter 114, and the first cutter 114 is fixed on the first rotating seat 111. The first cutter 114 corresponds to the first clearance long groove 117.

[0067] When the first adsorption plate 112 presses on the third adsorption plate 122, the spring 118 can buffer the pressure between the two, thus preventing the tape or the material tape from being damaged.

[0068] When the second adsorption plate 113 presses on the fourth adsorption plate 123, the spring 118 compresses, and the second adsorption plate 113 moves towards the first rotating seat 111 side, causing the first cutter 114 to extend out of the first clearance long groove 117. The first cutter 114 can cut the working material tape or the tape of the new coil. Moreover, the second clearance long groove 126 can clear the first cutter 114. Thus, the use of the driving device can be reduced, saving the equipment cost.

[0069] Furthermore, both the first adsorption plate 112 and the second adsorption plate 113 are provided with a plurality of guide posts 119, and the rotating seat is provided with a plurality of sliding sleeves 110. The plurality of sliding sleeves 110 are respectively in sliding fit with the plurality of guide posts 119. When the first adsorption plate 112 or the second adsorption plate 113 is stressed, the spring 118 compresses, and the first adsorption plate 112 or the second adsorption plate 113 moves towards the first rotating seat 111 side. At the same time, it drives the plurality of guide posts 119 to slide with the plurality of sliding sleeves 110 respectively. Thus, the stability of the first adsorption plate 112 or the second adsorption plate 113 during movement is improved, preventing shaking and improving the accuracy of tape cutting and tape pasting.

[0070] Refer to Figure 5 and Figure 6 , for the glue preparation mechanism 2, it includes a glue unwinding assembly 21 and a glue pulling assembly 22. The glue unwinding assembly 21 is used for unwinding the tape, and the glue pulling assembly 22 is used for pulling the tape onto the first adsorption plate 112 or the third adsorption plate 122.

[0071] Further, the glue releasing assembly 21 includes a first bottom plate 211, a fifth power member 212 for driving the first bottom plate 211 to translate, a glue unrolling roller 213, a guide roller 214, a first clamping jaw 215, a glue cutting module 216, and a first glue pressing module 217 provided on the first bottom plate 211.

[0072] Referring to Figure 7 , specifically, the glue cutting module 216 is located between the first clamping jaw 215 and the first glue pressing assembly. The first clamping jaw 215 is used to clamp or release the tape. The glue cutting module 216 includes a second cutter 2161 and a first cylinder 2162 for driving the second cutter 2161 to approach or move away from the tape. The first cylinder 2162 is provided on the first bottom plate 211. The first glue pressing module 217 includes a first support 2171, a first pressing roller 2172 rotatably connected to the first support 2171, and a second cylinder 2173 for driving the first support 2171 to approach or move away from the tape.

[0073] More specifically, a damper 218 is provided on the other side of the first bottom plate 211. The damper 218 is connected to one end of the glue unrolling roller 213. When the glue unrolling roller 213 unrolls the tape, the damper 218 is used to apply a resistance in the rotational direction to the glue unrolling roller 213, thereby increasing the tension of the tape and preventing the tape from wrinkling.

[0074] Referring to Figure 8 , further, the glue pulling assembly 22 includes a second bottom plate 221, a sixth power member 222 for driving the second bottom plate 221 to translate, a second clamping jaw 223, and a second glue pressing module 224 provided on the second bottom plate 221. The second clamping jaw 223 is used to clamp or release the head of the tape. The second glue pressing module 224 includes a swing arm 2241, a second pressing roller 2242 rotatably connected to one end of the swing arm 2241, and a seventh power member 2243 for driving the swing arm 2241 to rotate.

[0075] For convenient positioning, a first positioning sensor 219 is provided on the first bottom plate 211, and a second positioning sensor 225 is provided on the second bottom plate 221.

[0076] When applying glue, the first clamping jaw 215 clamps the head of the tape. The sixth power component 222 drives the second bottom plate 221 closer to the first bottom plate 211, so that the second clamping jaw 223 approaches the first clamping jaw 215. The second clamping jaw 223 grabs the head of the tape. Then, the first clamping jaw 215 releases. The sixth power component 222 drives the second bottom plate 221 away from the first bottom plate 211. The unwinding roller 213 unwinds the tape. The second bottom plate 221 drives the second clamping jaw 223 to pull the tape onto the first adsorption plate 112 or the third adsorption plate 122. At the same time, the second cylinder 2173 drives the first pressing roller 2172 to press the tape tightly against the first adsorption plate 112 or the third adsorption plate 122. The seventh power component 2243 drives the swing arm 2241 to swing, and the swing arm 2241 drives the second pressing roller 2242 to press the tape tightly against the first adsorption plate 112 or the third adsorption plate 122. When the second positioning sensor 225 senses the position of one end of the first adsorption plate 112 or the third adsorption plate 122, the second clamping jaw 223 releases. The sixth power component 222 first moves a certain distance further, so that one end of the tape is pressed on the first adsorption plate 112 or the third adsorption plate 122. Subsequently, the sixth power component 222 stops operating. The seventh power component 2243 drives the swing arm 2241 to swing to drive the second pressing roller 2242 to release. Then, the fifth power component 212 drives the first bottom plate 211 away from the second bottom plate 221. The first bottom plate 211 drives the first pressing roller 2172 to move and press the tape tightly against the first adsorption plate 112 or the third adsorption plate 122. When the first positioning sensor 219 determines that the tape reaches the other end of the first adsorption plate 112 or the third adsorption plate 122, the fifth power component 212 stops operating. Finally, the first cylinder 2162 drives the second cutting knife 2161 closer to the tape to cut the tape. The second cylinder 2173 drives the first pressing roller 2172 to release, completing one operation of reserving the tape. Thus, the tape can be automatically and accurately provided onto the first adsorption plate 112 and the third adsorption plate 122, improving production efficiency.

The third cylinder 2153 is arranged on the first bottom plate 211; the second clamping jaw 223 includes a second fixed clamping plate 2231, a second movable clamping plate 2232, and a fourth cylinder 2233 for driving the second movable clamping plate 2232 to approach or move away from the second fixed clamping plate 2231. The fourth cylinder 2233 is fixed on the second bottom plate 221 through a mounting plate.

[0078] Specifically, both the first fixed clamping plate 2151 and the first movable clamping plate 2152 are provided with first concave-convex teeth, and both the second fixed clamping plate 2231 and the second movable clamping plate 2232 are provided with second concave-convex teeth. The first concave-convex teeth and the second concave-convex teeth are misaligned and matched with each other, so that the second clamping jaw 223 can be prevented from interfering with the first clamping jaw 215 when grasping the material head of the tape.

[0079] In some preferred embodiments, the glue preparation mechanism 2 further includes a support plate 23. A rack 231 is provided on the support plate 23, and the length direction of the rack 231 is the same as the length direction of the support plate 23. The fifth power member 212 includes a transverse movement plate 2121, a motor 2122 installed on the transverse movement plate 2121, and a gear 2123 provided at the output end of the motor 2122. The gear 2123 meshes with the rack 231. The first bottom plate 211 is fixed to one side of the transverse movement plate 2121. Moreover, a second linear guide 2124 is provided between the transverse movement plate 2121 and the support plate 23. The motor 2122 drives the gear 2123 to rotate, and the gear 2123 meshes with the rack 231 to drive the transverse movement plate 2121 to move along the length direction of the support plate 23, so that the first bottom plate 211 can be driven to move along the length direction of the support plate 23.

[0080] It should be noted that the structure of the fifth power member 212 is the same as that of the sixth power member 222.

[0081] Refer to Figure 9 , in some preferred embodiments, the tape traction mechanism 3 includes an adsorption assembly 31 and a moving assembly 32. The adsorption assembly 31 is used to adsorb the material head of the new coil. The adsorption assembly 31 includes a third rotating seat 311, a plurality of suction cups 312 provided on the third rotating seat 311, and an eighth power member 313 for driving the third rotating seat 311 to rotate. The moving assembly 32 is used to drive the adsorption assembly 31 to reciprocate between the fourth adsorption plate 123 and the new coil.

[0082] Specifically, the eighth power member 313 is a rotary cylinder, and there are two eighth power members 313 and moving assemblies 32.

[0083] When pulling the strip of the new coil material, the moving assembly 32 drives the adsorption assembly 31 to approach the new coil material, so as to drive a plurality of suction cups 312 to move to one side of the strip head of the new coil material. Then, the plurality of suction cups 312 suck the strip head of the new coil material. Then, the moving assembly 32 drives the adsorption assembly 31 to move above the fourth adsorption plate 123. At this time, the eighth power member 313 drives the third rotating seat 311 to rotate to drive the plurality of suction cups 312 to face the side of the fourth adsorption plate 123. Then, the fourth power member 125 drives the second rotating seat 121 to approach the third rotating seat 311, so that the fourth adsorption plate 123 abuts against the strip on the suction cup 312. The fourth adsorption plate 123 sucks the strip, and the plurality of suction cups 312 release the strip. Finally, the moving assembly 32 drives the adsorption assembly 31 to move to the standby position. Thus, the strip head of the new coil material can be accurately pulled onto the fourth adsorption plate 123.

[0084] Further, the moving assembly 32 includes a first moving module 321 and a second moving module 322. The second moving module 322 is arranged on the first moving module 321, and the adsorption assembly 31 is arranged on the second moving module 322. The moving directions of the first moving module 321 and the second moving module 322 are the same. Thus, a longer moving distance can be achieved within a limited space, making the overall structure of the device more compact.

[0085] In some preferred embodiments, the waste collection mechanism 4 includes a waste box 41 and a ninth power member 42. The ninth power member 42 is arranged on the frame 5. The ninth power member 42 is used to drive the waste box 41 to approach or move away from the second rotating seat 121. The waste box 41 is used to receive the tail material after cutting.

[0086] After the strip head of the new coil material is cut off, the tail material is sucked by the right adsorption part of the fourth adsorption plate 123. The fourth power member 125 drives the second rotating seat 121 to move away from the first rotating seat 111. The third power member 124 drives the second rotating seat 121 to rotate to drive the fourth adsorption plate 123 outwards. Then, the ninth power member 42 drives the waste box 41 to approach one side of the second rotating seat 121, so that the waste box 41 is located directly below the fourth adsorption plate 123. Then, the right adsorption part of the fourth adsorption plate 123 releases the tail material, and the tail material falls into the waste box 41. Finally, the ninth power member 42 drives the waste away from the second rotating seat 121 to complete the collection of the tail material.

Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
