If the specific posture changes, the directional indication will also change accordingly. In addition, if there is a description of "first", "second", etc. in the embodiment of the present invention, the description of "first", "second", etc. is only used for descriptive purposes and cannot be understood as indicating or implying its relative importance or implicitly indicating the number of the indicated technical features.

[0029] like Figure 1-Figure 6As shown, an automatic film-sticking device for ceramic tiles comprises a frame 1, a centering device 2, a conveyor belt 5, two pressure roller devices 3 and a cutter device 4. The conveyor belt 5 is arranged on the frame 1 and driven by a motor. The centering device 2, the two pressure roller devices 3 and the cutter device 4 are all arranged on the frame 1 and arranged above the conveyor belt 5 in sequence along the conveying direction of the conveyor belt 5. The function of the pressure roller device 3 is to cover the film on the surface of the ceramic tile, and the function of the cutter device 4 is to cut the film from the gap between two adjacent ceramic tiles on the conveyor belt 5 to complete the film-sticking process. Furthermore, the conveyor belt 5 comprises a centering conveying section 51 and a film-sticking conveying section 52. The centering device 2 is installed on the centering conveying section 51, and the pressure roller device 3 and the cutter device 4 are installed on the film-sticking conveying section 52.

[0030] The pressure roller device 3 includes a traction roller 32, a bracket 31, a feeding part 34 and a main pressure roller 33. The traction roller 32, the feeding part 34 and the main pressure roller 33 are all arranged on the bracket 31. The feeding part 34 includes a material bin 341 and a clamping part 342 for clamping a film roll. The material bin 341 and the clamping part 342 are both arranged on the bracket 31, and the clamping part 342 is rotatably matched with the bracket 31. The function of the pressure roller device 3 is to cover the ceramic tile sent by the conveyor belt 5 with a film. The film roll is placed on the clamping part 342 and can rotate. One end of the film roll bypasses the traction roller 32 and is then wound onto the main pressure roller 33. The traction roller 32 plays the role of traction of the film, and the main pressure roller 33 makes the film close to the surface of the ceramic tile. Furthermore, the clamping component 342 includes a clamping seat 3421, a clamping cylinder 3422, a clamping head 3424 and a connecting seat 3423. The clamping seat 3421 is fixed on the support plate 311 of the bracket 31, the clamping cylinder 3422 is installed on the clamping seat 3421, and the connecting seat 3423 is fixed to one end of the piston rod of the clamping cylinder 3422. The clamping cylinder 3422 drives the connecting seat 3423 to move horizontally, and the clamping head 3424 can be rotatably set on the connecting seat 3423. The clamping head 3424 is set in a truncated cone shape, and the ends with smaller diameters of the two clamping heads 3424 are opposite to each other, and a clamping position for clamping the film roll is formed between the two clamping heads 3424. The clamping cylinder 3422 drives the connecting seat 3423 to move from the outside of the conveyor belt 5 to the middle of the conveyor belt 5, and the connecting seat 3423 drives the clamping head 3424 to move. The two clamping heads 3424 are driven by the clamping cylinder 3422 to approach each other. Therefore, since the two clamping heads 3424 are both truncated cone-shaped structures, when the two clamping heads 3424 extend into the paper tube of the film roll under the action of the clamping cylinder 3422, the two clamping heads 3424 can lift the top of the film roll to make the film roll leave the silo 341, completing the loading process.

[0031] The above-mentioned automatic film-sticking equipment for ceramic tiles has a centering device 2, two roller devices 3 and a cutting device 4 arranged above the conveyor belt 5 along the conveying direction of the conveyor belt 5. The ceramic tiles enter from one end of the conveyor belt 5, are centered by the centering device 2, and then are pasted with films by the roller device 3, and then are sent to the cutting device 4. The cutting device 4 cuts off the film between the front and rear ceramic tiles on the conveyor belt 5 to complete the film-sticking process. The ceramic tiles pasted with films are sent out through the conveyor belt 5 and enter the next process. The film-sticking process of the equipment is fully automated. Two roller devices 3 are arranged on the conveyor belt 5. When the film roll of one roller device 3 is used up, it automatically switches to the other roller device 3 for film-sticking operation. No manual operation is required, and the film-sticking efficiency is high. Moreover, when replacing the film roll, it is only necessary to place the new film roll in the silo 341, start the clamping component 342, and the clamping component 342 can clamp the film roll to complete the replacement. The film roll replacement is simple and convenient, eliminating safety hazards.

[0032] More specifically, the working process of the equipment is as follows: the tiles to be filmed are loaded from the centering conveying section 51 of the conveyor belt 5, and the centering device 2 starts working to push the tiles to the middle of the centering conveying section 51, that is, the middle of the entire conveyor belt 5 along the width direction. The centering device 2 pushes the tiles to the middle of the conveyor belt 5 to ensure that the film roll can fully cover the surface of the tiles during filming, thereby ensuring the filming effect. The centered tiles are continuously conveyed by the conveyor belt 5 to the two pressing roller devices 3, which are arranged in parallel along the conveying direction of the conveyor belt 5 and span above the conveyor belt 5. Therefore, both of the two pressing roller devices 3 can apply film to the tiles, and in actual application, only one of the pressing roller devices 3 is required for filming. When in use, one of the pressing roller devices 3 applies film to the tiles, and when the film roll on it is used up, the pressing roller device 3 stops working and reminds the operator to replace the film roll through the control system. At this time, the other pressing roller device 3 starts automatically to apply film to the tiles. Switching back and forth between the two pressure roller devices 3 can keep the entire device working continuously, so the film-sticking efficiency of the entire device is high. In the process of replacing the film roll, there is no need to stop the operation. The operator only needs to place the film roll on the silo 341. It should be noted that when preventing the film roll, the length direction of the film roll should be consistent with the width direction of the conveyor belt 5. After the film roll is placed on the silo 341, the clamping component 342 is started. The clamping component 342 clamps the film roll so that the film roll is separated from the silo 341, and the loading process can be completed. The entire loading process only requires the use of equipment to lift the film roll to the silo 341, without manual operation, which is time-saving, efficient and safe. The tiles that have been film-sticked by the pressure roller device 3 are further transported to the cutter device 4. There is a gap between the two adjacent tiles on the conveyor belt 5. The cutter device 4 cuts the film from the gap, and then the tiles are continued to be sent out. At this point, the entire film-sticking process is completed. The cutting device 4 is a prior art and has been widely used in the field of tile machinery, so its structure is not described in detail here. It should be noted that the cutting blade of the cutting device 4 should be able to be replaced with cutting blades of different widths according to different tile widths, which can ensure that the cutting device 4 can quickly cut the film on the tile.

[0033] Furthermore, the support 31 includes two support plates 311 of the same structure, the two support plates 311 are respectively arranged on opposite sides of the conveyor belt 5, and each support plate 311 is respectively installed with a clamping component 342 corresponding to each other, and the clamping component 342 is located above the silo 341; the silo 341 includes two connecting rods 3411 that can move up and down on the support plate 311, and the two connecting rods 3411 are arranged in parallel. The two support plates 311 are arranged on both sides of the conveyor belt 5 and correspond to each other to form the support 31 of the roller device 3, and the support plates 311 can be fixed to the frame 1 by bolts. The two connecting rods 3411 are arranged in parallel, so the silo 341 for temporarily placing the film roll is formed between the two connecting rods 3411. It should be noted that the relative distance between the two connecting rods 3411 is less than the outer diameter of the film roll. When loading, it is necessary to keep the paper tube of the film roll near the clamping head 3424. The two connecting rods 3411 can move up and down on the support plate 311. Therefore, the position of the connecting rods 3411 can be adjusted according to the film rolls of different diameters so that the paper tube of the film roll after loading can be kept near the clamping head 3424.

[0034] Furthermore, the main pressure roller 33 includes a first roller 332 and two first mounting parts 331. The two first mounting parts 331 are relatively arranged on both sides of the width direction of the conveyor belt 5. The first mounting part 331 includes a first cylinder 3312 and a first mounting seat 3311. The first cylinder 3312 is installed on the bracket 31. The first mounting seat 3311 is fixed on the piston rod of the first cylinder 3312 and is driven by the first cylinder 3312 to move up and down. The first roller 332 is arranged between the two first mounting seats 3311 and is rotatably matched with the first mounting seat 3311. After the first roller 332 is installed on the first mounting seat 3311, the expansion and contraction of the piston rod of the first cylinder 3312 will drive the first mounting seat 3311 to move up and down, that is, the distance between the bottom of the first roller 332 and the surface of the conveyor belt 5 can be changed, so that the first roller 332 can better stick the film to the surface of the tile.

[0035] Furthermore, the roller device 3 further comprises an auxiliary roller 35, which is located upstream of the main roller 33 along the conveying direction of the conveyor belt 5, and comprises a driving device 351 and a second roller 352, wherein one driving device 351 is provided on each support plate 311; the driving device 351 comprises a second cylinder 3512 and a crank arm 3511, wherein the second cylinder 3512 is fixed on the support plate 311, wherein the middle part of the crank arm 3511 is rotatably matched with the support plate 311, wherein one end of the crank arm 3511 is connected to the piston rod of the second cylinder 3512, and the other end of the crank arm 3511 is connected to a guide rod, and the two ends of the second roller 352 are rotatably matched with one of the guide rods 3513. Furthermore, a guide groove 3111 is provided on the support plate 311, and the connecting rod 3411 passes through the guide groove 3111 and is connected to the second roller 352. The guide groove 3111 is set on the bracket 31 at a certain angle to the horizontal plane, and the function of the guide groove 3111 is to guide the movement of the guide rod 3513. The piston rod of the second cylinder 3512 is extended and retracted, driving the crank arm 3511 to rotate, and the rotating crank arm 3511 drives the second roller 352 to move up and down, which can change the distance between the second roller 352 and the surface of the conveyor belt 5. In the film pasting process, the film on the film roll first bypasses the traction roller 32, then bypasses the second roller 352, and finally falls under the first roller 332. The second roller 352 first flattens the film so that the film covers the surface of the tile, and then the tile passes through the first roller 332, and the first cylinder 3312 drives the first roller 332 to press down so that the film is tightly attached to the surface of the tile.

[0036] Furthermore, the pressure roller device 3 also includes a suction cup assembly 38. Along the conveying direction of the conveyor belt 5, the suction cup assembly 38 is located upstream of the auxiliary pressure roller 35. The bracket 31 is provided with a crossbeam 36. The crossbeam 36 is provided with a third cylinder 37 pointing vertically downward. The suction cup assembly 38 is fixed on the piston rod of the third cylinder 37. Before film pasting and after loading, the suction cup assembly 38 absorbs the end of the film roll to complete the preparation work. Then, when the tile is sent to the bottom of the suction cup assembly 38, the third cylinder 37 is started to send the suction cup assembly 38 to the top of the tile, driving the end of the film roll downward, and the suction cup assembly 38 blows air to loosen the film and press the film roll down on the surface of the tile. At this time, the piston rod of the third cylinder 37 retracts and brings back the suction cup assembly 38. The suction cup assembly 38 should include a suction cup and a vacuum generating device. The vacuum generating device is connected to the suction cup. The vacuum generating device absorbs air, and the suction cup can absorb the film. The vacuum generating device blows air, and the film falls off the suction cup and covers the surface of the tile.

[0037] In general, the working process of the automatic film sticking equipment is as follows: the pressure roller device 3 is prepared before starting, the film roll is placed on the silo 341, the clamping component 342 is started to clamp the film roll, and then the suction cup assembly 38 is started to adsorb the end of the film roll to complete the preparation work. At this time, both pressure roller devices have complete film rolls. The working process is that the tile passes under the suction cup assembly 38, the third cylinder 37 drives the suction assembly downward and makes the third cylinder 37 and the suction cup assembly 38 press the film roll down to the surface of the tile, and then the suction cup assembly 38 is reset, and the auxiliary pressure roller 35 is pressed down to flatten the film to prevent the end of the film from rolling up and the bottom surface from sticking to the main pressure roller when the new film roll is pasted on the first tile. After the first tile is pressed, the subsequent tiles are normally pasted under the action of the pressure roller device. When switching workstations: a film shortage alarm is sounded, and then the film sticking workstation is automatically switched, the original film sticking workstation stops working, and the new workstation enters the working state, and the operator presses the stop alarm to prepare for the start-up of the pressing roller device 3 of the original workstation. The two workstations work in this cycle to efficiently stick films on tiles.

[0038] Furthermore, a film-missing signal monitor 39 is installed on the bracket 31. The film-missing signal monitor 39 is an infrared detector. After the film-missing signal monitor 39 detects that there is no film roll on the pressing roller device 3, an alarm is issued through the control system of the entire device to remind the operator to replace the film roll.

[0039] Furthermore, two centering devices 2 are provided, and the two centering devices 2 are respectively provided on opposite sides of the centering conveying section 51. The centering device 2 comprises a base 21, a centering cylinder 22, a limit plate 23 and a centering wheel set 24. The base 21 is fixed on the frame 1, the centering cylinder 22 is installed on the base 21, the limit plate 23 is fixed on the piston rod of the centering cylinder 22, the centering cylinder 22 drives the limit plate 23 to move from the edge to the middle of the centering conveying section 51, and the centering wheel set 24 is provided on the limit plate 23. The two centering cylinders 22 are controlled by the control system and can move synchronously, so that the limit plate 23 is pushed from the edge of the conveying belt 5 to the middle of the conveying belt 5. The two centering cylinders 22 work simultaneously to deliver the tiles to the middle of the centering conveying section 51, which is convenient for the subsequent film pasting operation.
