[0034] The utility model uses an intermittent cap transporting assembly, and can use a structural setting that includes multiple positioning columns in each group. Under the action of the feeding assembly, multiple bottle caps are simultaneously transported to a group of positioning columns, so that one end of the bottle cap opening is plugged and matched with the positioning column to facilitate positioning and film laminating. At the same time, under the action of the rotatable roller, each group of positioning columns carries the bottle cap located on the positioning column to change position every time it rotates an angle, so as to drive multiple bottle caps to move synchronously to different processing, thereby effectively improving the film laminating efficiency and realizing the processing of multiple bottle caps at one time.

[0035] According to the working principle of the utility model, the feeding component 50 is used to simultaneously convey multiple bottle caps to a group of positioning posts 220, so that the bottle caps 100 are plugged and matched with the positioning posts 220 to form a positioning match, and then under the action of the first rotating element 200, it drives the roller 210 to rotate a preset angle, so that the positioning posts 220 carrying the bottle caps 100 are rotated to the film laminating station, at this time, the bottle caps 100 are laminated by the film laminating component 30, and then the roller 210 is rotated a preset angle again, so that the positioning posts 220 carrying the bottle caps 100 are rotated to the secondary heating station, and the film is reheated by the secondary heating component 90, so that the film is firmly laminated on the bottle caps 100, and finally, the roller 210 is rotated again by a preset angle, so that the positioning posts 220 carrying the bottle caps 100 are rotated to the unloading station, and at this time, the bottle caps 100 that have been laminated are removed by the unloading component 80 to complete the entire processing flow.

[0036] Furthermore, the first rotating element 200 is driven by a servo motor and a reduction gearbox, and the servo motor drives the reduction gearbox to drive the roller shaft 210 to rotate.

[0037] In the utility model, the bottle cap 100 is a smart cap used for existing bottled water, and the function of the film is to protect the surface of the smart cap to prevent dust and other impurities from adhering to the surface of the smart cap and affecting the normal use in the later stage.

[0038] See also Figure 3 The film laminating assembly 30 includes a mounting frame 310 fixedly mounted on the frame 10, a positioning plate 330 is disposed on the mounting frame 310 above the roller 210, and a through hole 331 is disposed at a position of the positioning plate 330 corresponding to the positioning column 220;

[0039] A movable plate 340 is disposed above the positioning plate 330, and the movable plate 340 is disposed to move up and down relative to the mounting frame 310. The movable plate 340 is provided with a mounting hole at a position corresponding to the through hole 331, and a ring-shaped cutter 341 is disposed in the mounting hole.

[0040] A moving frame 350 is arranged above the moving plate 340, and the moving frame 350 is arranged to move up and down relative to the mounting frame 310. A mounting rod 360 is arranged at a position of the mounting frame 310 corresponding to the through hole 331. A concave cavity 362 is arranged at the bottom of the mounting rod 360. A first suction cup 363 for adsorbing a film is arranged in the concave cavity 362. A heating element 361 is installed in the mounting rod 360. The mounting rod 360 around the concave cavity 362 forms a convex ring 364 for pressing the film downward.

[0041] The mounting frame 310 is provided with a first linear element 370 and a second linear element 380. The first linear element 370 is used to drive the movable plate 340 to move up and down relative to the mounting frame 310. The second linear element 380 is used to drive the movable frame 350 to move up and down relative to the mounting frame 310.

[0042] The mounting frame 310 is provided with film wheels 320 on the left and right sides respectively, wherein one film wheel 320 is used for unwinding the film, and the other film wheel 320 is used for winding the used film, and the film is passed between the moving plate 340 and the positioning plate 330 .

[0043] Film laminating principle: during the laminating process, the positioning column 220 rotates with the roller 210, which drives the bottle cap 100 to the bottom of the through hole 331. At this time, the second linear element 380 drives the moving frame 350 to move downward. During this process, the moving frame 350 drives the mounting rod 360 and the second suction cup 363 to move downward. The mounting rod 360 passes through the mounting hole and the annular cutter 341 and moves downward to adsorb the film through the first suction cup 363. Then, the first linear element 370 drives the movable plate 340 to move downward. When the movable plate 340 moves downward, the annular cutter 341 is driven downward to cut off the film adsorbed by the first suction cup 353. The cut film remains on the first suction cup 353. At this time, the second linear element 380 continues to drive the movable frame 350 to move downward until the first suction cup 353 drives the cut film to adhere to the surface of the bottle cap 100. At this time, the heating element 361 is energized and dissipates heat, so that the film adheres to the surface of the bottle cap 100 to complete the film sticking work. The first linear element 370 and the second linear element 380 perform the resetting work.

[0044] Furthermore, the first linear element 370 and the second linear element 380 are driven by a pneumatic cylinder or an electric cylinder.

[0045] See also Figures 5 to 7 The feeding assembly 50 includes a first conveying line 40, and the first conveying line 40 is used to convey the bottle caps 100 one by one toward the axis direction of the roller 210;

[0046] The first conveying line 40 is divided into a conveying area 410 and a loading area 420. A material blocking assembly 60 is disposed between the conveying area 410 and the loading area 420. A material blocking member 430 is disposed at the end of the first conveying line 40.

[0047] The frame 10 is provided with a first cylinder 510, a movable seat 520 is installed on the cylinder shaft of the first cylinder 510, a positioning seat 550 is installed on the movable seat 520, a plurality of positioning cavities 560 corresponding to the bottle caps 100 are arranged on the positioning seat 550 along the conveying direction of the first conveyor line 40, the positioning cavity 560 is opened toward one side of the bottle caps 100, a push rod 530 is arranged in the positioning cavity 560 and is movable relative to the positioning cavity 560, and a second cylinder 540 for driving the push rod 530 to move relative to the positioning cavity 560 is arranged on the movable seat 520 or the positioning seat 550.

[0048] See also Figure 5 A sixth cylinder 1001 is provided on the frame 10 between the feeding area 420 and the roller 210, and a limit plate 1002 is installed on the cylinder shaft of the sixth cylinder 1001. The sixth cylinder 1001 drives the limit plate 1002 to move, so that the limit plate 1002 can be moved between the feeding area 420 and the roller 210.

[0049] Furthermore, the first conveyor line 40 is a conveyor belt.

[0050] See also Figure 7 The conveying direction of the first conveyor line 40 is from left to right, the roller 210 is located at the front side of the loading area 420, and the first cylinder 510, the positioning seat 550 and the push rod 530 are located at the rear side of the first conveyor line 40. The first conveyor line 40 is used to convey the bottle caps from the conveying area 410 to the loading area 420 in sequence, and the blocking member 430 can prevent the bottle caps 100 from falling off from the end of the first conveyor line 40.

[0051] When the bottle cap 100 is transported from the loading area 420 to the positioning column 220 of the roller 210, the first cylinder 510 first drives the moving seat 520 to move, so that the positioning seat 550, the push rod 530 and the second cylinder 540 move toward the bottle cap 100. At this time, the bottle cap 100 is blocked by the limiting plate 1002 and cannot move toward the positioning column 220, so that the bottle cap 100 enters the positioning cavity 560 of the positioning seat 550. The function of the positioning cavity 560 is to allow the bottle cap to enter the cavity so that the bottle cap 100 and the positioning column 220 can be accurately inserted. After the bottle cap 100 enters the positioning cavity 560, the sixth cylinder 1001 is started, which drives the limiting plate 1002 to move downward to release the limit. At this time, the first cylinder drives the movable seat 520 to move, so that the positioning seat 550 drives the bottle cap 100 to move toward the positioning column 220 until the bottle cap 100 and the positioning column 220 are plugged in. After the plug-in assembly is completed, the first cylinder drives the movable seat 520 to move backward for reset. While resetting, the second cylinder 540 drives the push rod 530 to move forward. At this time, the function of the push rod 530 is that when the positioning seat 550 moves backward and needs to be separated from the bottle cap 100, the push rod 530 can restrain the bottle cap 100 so that it will not be affected by the backward movement of the positioning seat 550, so that the bottle cap 100 is firmly plugged into the positioning column 220.

[0052] See also Figure 5 and Figure 6 The second cylinder 540 is arranged on the moving seat 520, the push rod 530 is fixedly connected with a connecting rod 570, the positioning seat 550 is provided with a through hole penetrating the positioning seat 550, and the push rod 530 passes through the through hole and is fixedly connected with the cylinder shaft of the second cylinder 540.

[0053] Furthermore, the connecting rod 570 is fixed on the moving seat 520 .

[0054] See also Figure 4 The secondary heating assembly 90 includes a movable base 920 movably arranged on the frame 10, and a plurality of heating elements 930 corresponding to the positioning column 220 are arranged on the movable base 920 along the axial direction of the roller shaft 210. A third cylinder 910 is installed on the frame 10 for driving the movable base 920 to move toward or away from the positioning column 220.

[0055] The heating element 930 adopts the existing heating element, which can generate heat when connected to electricity. Under the action of the third cylinder 910, it can drive the heating element 830 to be pressed on the bottle cap 100 with the film.

[0056] See also Figure 4The unloading assembly 80 includes a second conveying line 70 for conveying bottle caps 100 disposed on the frame 10 below the roller 210;

[0057] The unloading assembly 80 also includes a first rotating shaft 810 rotatably arranged on the frame 10, the first rotating shaft 810, the frame 10 is provided with a second rotating element 800 for driving the first rotating shaft 810 to rotate, the second rotating element 800 is installed with a fourth cylinder 820, the cylinder shaft of the fourth cylinder 820 is installed with a fixing plate 830, and the fixing plate 830 is arranged along the axial direction of the roller shaft 210 with a plurality of second suction cups 840 corresponding to the positioning column 220.

[0058] The function of the second suction cup 840 is that when it is attached to the bottle cap 100, the surfaces of the second suction cup 840 and the bottle cap 100 that are attached to each other form a vacuum adsorption cavity, so that the bottle cap 100 is firmly adsorbed on the second suction cup 840. Then, under the rotation of the first rotating shaft 810, it can drive the second suction cup 840 to rotate, so that the second suction cup 840 changes its position, so as to remove the bottle cap 100 from the positioning column 220, and then place the bottle cap 100 on the second conveyor line 70. The fourth cylinder 820 is used to drive the fixing plate 830 to move, so as to change the linear position of the second suction cup 840.

[0059] Furthermore, the second conveying line 70 adopts a conveyor belt.

[0060] See also Figure 7 The material blocking assembly 60 includes a fifth cylinder 610 arranged on the frame 10, and a blocking member 620 is installed on the cylinder shaft of the fifth cylinder 610. The fifth cylinder 610 is used to drive the blocking member 620 to move between the conveying area 410 and the loading area 420 or drive the blocking member 620 to leave from between the conveying area 410 and the loading area 420.

[0061] The first conveyor line 40 is a conveyor belt, which can drive the bottle caps 100 to move from the conveying area 410 to the loading area 420 when conveying the bottle caps 100. When the bottle caps 100 completely fill the loading area 420, the fifth cylinder 610 can drive the blocking member 620 to move between the conveying area 410 and the loading area 420 to block the bottle caps from entering the loading area 420, so as to avoid the first conveyor line 40 continuously feeding when the positioning seat 550 pushes the material forward, so as to avoid affecting the normal operation of the equipment.
