[0043] Reference Figures 1 to 7 , a bottle cap packaging production line, including a loading device 100, a first feeding conveyor line 200, a palletizing device 300 and a packaging device 400;

[0044] The feeding device 100 is used to provide bottle caps;

[0045] The first feeding conveyor line 200 is provided with a plurality of horizontal first feeding stations at intervals;

[0046] The palletizing device 300 is connected between the loading device 100 and the first feeding conveyor line 200, and is used to stack the bottle caps on the first feeding station into a horizontal stack of bottle caps;

[0047] The packaging device 400 is connected to the discharge end of the first feeding conveyor line 200 and is used to perform plastic-sealing packaging on the bottle cap stacks.

[0048] 1) Reference Figure 1-Figure 3In some embodiments, the loading device 100 includes a feed hopper 110, a lifting line 120, a feeding chute 130 and a first material transfer assembly 140; the feed hopper 110 is used to store bottle caps; the feeding end of the lifting line 120 is connected to the feed hopper 110 for lifting the bottle caps to a high place; the feeding chute 130 is connected to the discharge end of the lifting line 120 for arranging the bottle caps into rows; the first material transfer assembly 140 is connected between the feeding chute 130 and the palletizing device 300 for transferring the bottle caps to the palletizing device 300 row by row.

[0049] Specifically, the bottle caps are placed in the feed hopper 110, lifted to a higher position by the lifting line 120, and then enter the feeding chute 130 from the discharge end of the lifting line 120. The feeding chute 130 includes a first straight end 131, an S-shaped segment 132, and a second straight segment 133 connected in sequence. The second straight segment 133 is connected to the palletizing device 300. The bottle caps are arranged in a row in the second straight segment 133 and are transferred to the palletizing device 300 in the form of a whole row by the first material transfer assembly 140.

[0050] 2) Reference Figure 1-Figure 3 Furthermore, the first material moving assembly 140 includes a material moving box 141 and a first driving assembly 142. The material moving box 141 has a side opening and a lower opening; the end of the feeding chute 130 has an upper opening; the side opening of the material moving box 141 is connected to the discharge port of the feeding chute 130, and the lower opening is connected to the upper opening of the feeding chute 130, so that the bottle caps in the feeding chute 130 enter the material moving box 141; the first driving assembly 142 is connected to the material moving box 141, and is used to drive the material moving box 141 to move back and forth between the feeding chute 130 and the palletizing device 300.

[0051] Specifically, the upper end opening of the end of the feeding slide 130 is composed of a second straight segment 133, that is, the transfer box 141 is located above the second straight segment 133, and the bottle caps are arranged in a row in the space enclosed by the transfer box 141 and the second straight segment 133, and are scraped by the transfer box 141 to the palletizing device 300 under the drive of the first drive component 142, specifically, to the belt conveyor line 310.

[0052] 3) Reference Figure 1-Figure 3 In some embodiments, a palletizer for bottle caps further includes a supporting slide 500 docked between the feeding chute 130 and the palletizing device 300, and the material transfer box 141 is located above the supporting slide 500, and the height of the supporting slide 500 gradually decreases along the feeding chute 130 toward the palletizing device 300.

[0053] Specifically, the supporting slide 500 is connected between the second straight segment 133 and the palletizing device 300 (belt conveyor line 310), and serves as a supporting bridge for the bottle caps in the process of the transfer box 141 scraping the bottle caps from the second straight segment 133 to the palletizing device 300. Furthermore, the height of the supporting slide 500 is gradually lowered along the feeding slide 130 toward the palletizing device 300, so that after the transfer box 141 scrapes the bottle caps into the palletizing device 300, there is a height difference between the bottle caps and the transfer box 141, which will not hinder the resetting of the transfer box 141.

[0054] 4) Reference Figure 1-Figure 5 In some embodiments, the palletizing device 300 includes a belt conveyor line 310, a plurality of dividing rods 320, and a plurality of dropping hoppers 330; the feeding end of the belt conveyor line 310 is connected to the loading device 100; the dividing rods 320 are arranged at the discharging end of the belt conveyor line 310 and are spaced apart along the width direction of the belt conveyor line 310 to separate a plurality of palletizing channels 340; the first feeding conveyor line 200 is located below the palletizing channels 340 and has an angle α with the belt conveyor line 310; the dropping hopper 330 is connected between the palletizing channels 340 and the first feeding conveyor line 200; the first feeding station can receive the bottle caps dropped from the dropping hopper 330 one by one when passing through the belt conveyor line 310, so that the bottle caps are stacked into a horizontal bottle cap stack on the first feeding station.

[0055] Specifically, after the first material moving assembly 140 transfers the bottle caps to the belt conveyor line 310, the belt conveyor line 310 drives the bottle caps to move forward until each row of bottle caps enters the corresponding stacking channel 340, and then falls into the corresponding drop hopper 330 one by one, and finally falls onto the first feeding conveyor line 200 below the drop hopper 330; specifically, while the bottle caps fall into the drop hopper 330, the first feeding conveyor line 200 also moves forward continuously. For example, when the first feeding conveyor line 200 drives the first first feeding station thereon to pass through the first drop hopper 330, due to the angle α between the first feeding conveyor line 200 and the belt conveyor line 310, The first bottle cap will be arranged at the first position of the first first feeding station; when the first feeding conveyor line 200 drives the first first feeding station thereon to pass through the second drop hopper 330, the second bottle cap will be arranged at the second position of the first first feeding station through the second drop hopper 330; when the first feeding conveyor line 200 drives the first first feeding station thereon to pass through the third drop hopper 330, the third bottle cap will be arranged at the third position of the first first feeding station... until the required quantity is stacked; it should be noted that baffles are provided at the front and rear ends of the drop hopper 330 to prevent the bottle caps from tipping forward or backward.

[0056] 5) Reference Figure 1-Figure 5In some embodiments, a palletizer for bottle caps further includes a material partitioning assembly 600 arranged between the belt conveyor line 310 and the drop hopper 330, for dropping the bottle caps on the belt conveyor line 310 into the drop hopper 330 row by row; as a preferred embodiment of the material partitioning assembly 600, the material partitioning assembly 600 includes a second drive assembly 610, a connecting plate 620 and a plurality of material blocking rods 630; the output end of the second drive assembly 610 is connected to the connecting plate 620; the connecting plate 620 extends along the width direction of the belt conveyor line 310; the material blocking rod 630 is installed on the connecting plate 620; the second drive assembly 610 can drive the connecting plate 620 to reciprocate along the width direction of the belt conveyor line 310, so that the material blocking rod 630 extends into the palletizing channel 340 or is withdrawn from the palletizing channel 340.

[0057] Specifically, at the first moment, the second drive assembly 610 drives the connecting plate 620 to drive the blocking rod 630 to be withdrawn from the palletizing channel 340, thereby removing the obstruction to the movement of the bottle caps in the palletizing channel 340, so that the bottle caps can smoothly enter the drop hopper 330; at the second moment, the second drive assembly 610 drives the connecting plate 620 to drive the blocking rod 630 to enter the palletizing channel 340, thereby blocking the movement of the bottle caps in the palletizing channel 340, thereby preventing the bottle caps from falling into the drop hopper 330 and affecting the arrangement of the bottle caps on the first feeding station.

[0058] 6) Reference Figure 1-Figure 5 In some embodiments, the first feeding conveyor line 200 includes a first chain loop component 210 and a plurality of first supporting rods 220 spaced apart on the first chain loop component 210 , and two adjacent first supporting rods 220 constitute a first feeding station.

[0059] 7) Reference Figure 1-Figure 2 and Figure 6-Figure 7 In some embodiments, the packaging device 400 includes a second feeding conveyor line 410, a film feeding assembly 420, a second material moving assembly 430 and a heat sealing assembly 440; a plurality of horizontal second feeding stations are arranged at intervals on the second feeding conveyor line 410; the film feeding assembly 420 is used to provide a packaging film located above the second feeding station; the second material moving assembly 430 is used to transfer the stack of bottle caps on the first feeding station to the second feeding station and press them on the packaging film; the heat sealing assembly 440 is used to heat seal the packaging film so that the packaging film covers the stack of bottle caps.

[0060] Specifically, the second feeding conveyor line 410 is parallel to the first feeding conveyor line 200 and adopts the same structure, that is, the second feeding conveyor line 410 includes a second chain circulation component and a plurality of second supporting rods spaced apart on the second chain circulation component, and two adjacent second supporting rods constitute a second feeding station; the working process of the packaging device 400 is as follows: the film feeding component 420 first conveys the packaging film to the top of the second feeding station, and the heat sealing component 440 performs the first heat sealing as the first side end seal of the packaging bag, and then the second material moving component 430 transfers the stack of bottle caps stacked on the first feeding conveyor line 200 to the sealed packaging film, so that the packaging film is pressed against the second feeding station under the action of the gravity of the bottle cap stack, and then the heat sealing component 440 performs the second heat sealing as the second side end seal of the packaging bag, thereby completing the heat sealing of the bottle cap stack; it should be noted that the front and rear end openings of the bottle cap stack can be heat sealed by the second heat sealing component, or can be shrunk by an overheating shrinking furnace.

[0061] 9) Reference Figure 1-Figure 2 and Figure 6-Figure 7 In some embodiments, the film feeding assembly 420 includes a first film storage roller 421, a second film storage roller 422, a first film feeding roller 423 and a second film feeding roller 424; the first film storage roller 421 and the first film feeding roller 423 are located on one side of the heat sealing assembly 440, for providing a first film body; the second film storage roller 422 and the second film feeding roller 424 are located on the other side of the heat sealing assembly 440, for providing a second film body; the heat sealing assembly 440 is used to heat seal the first film body and the second film body at their ends to form a packaging film.

[0062] Specifically, at the first moment, the first film feed roller 423 and the second film feed roller 424 respectively feed the film bodies on the first film storage roller 421 and the second film storage roller 422 from both sides of the second feeding station, and then the heat sealing component 440 performs the first heat sealing, and then the bottle cap stack is placed on the sealed packaging film. It should be noted that the second side end seal of the previous bottle cap stack serves as the first side end seal of the next bottle cap stack, and the cycle is repeated.

[0063] 10) Reference Figure 1-Figure 2 In some embodiments, a palletizer for bottle caps further includes a labeling device 700 and a third material transfer assembly 800. The labeling device 700 is used to provide labels, and the third material transfer assembly 800 is used to transfer the labels one by one to the packaging film. The packaging of the bottle cap stack also needs to be accompanied by a corresponding production label, which is marked with the production date, production batch number, product purpose, etc.

[0064] Specifically, the label distribution device 700 provides labels one by one. After the heat sealing component 440 seals the first side end of the packaging film, the third material transfer component 800 transfers the label to the packaging film with the first side end sealed, and then the second material transfer component 430 transfers the bottle cap stack to the packaging film and presses it against the label, and finally performs the second side end sealing.
