Description

A packaging machine Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a packaging machine. Background Technology

[0002] With technological advancements, eye patch packaging is now typically done using packaging machines, which significantly improves packaging efficiency compared to manual packaging. The process involves first folding the tray, placing the eye patch inside, and then placing the tray onto the first conveyor belt. The first conveyor belt transports the tray to the pushing area, where a pushing mechanism advances it onto the second conveyor belt. However, the tray may shift during transport on the first conveyor belt, resulting in an uneven position when it reaches the pushing area. This can cause the tray to become stuck on the packaging machine during pushing, potentially damaging the tray or the machine itself. Summary of the Invention

[0036] This invention relates to a packaging machine, comprising a frame, a first conveyor belt, a second conveyor belt, a guide member, and a pushing mechanism. Both the first and second conveyor belts extend in a front-to-back direction and are staggered left-to-right. A guide member is located at the rear of the first conveyor belt. During operation, box trays are conveyed from front to back by the first conveyor belt, entering a guide channel from the rear end of the first conveyor belt. The box trays within the guide channel move backward along the guide channel under the pushing action of other box trays in front. When a box tray moves to one side of the pushing mechanism, the pushing mechanism pushes the box tray towards the second conveyor belt. A guide member with a guide channel is located at the rear of the first conveyor belt. The box tray enters the guide channel through the inlet at the front end. Due to the wide inlet of the guide channel, even if the box tray deviates from its position on the first conveyor belt, it can still enter the guide channel. The box tray is conveyed backward along the guide channel, where the width gradually decreases. The walls on both sides of the guide channel contact the box trays, arranging them neatly. By gradually narrowing the front end of the guide channel, the box trays that deviate during the conveying process are arranged neatly, preventing the box trays from getting stuck on the packaging machine when the pushing mechanism pushes them, thus preventing damage to the box trays or the packaging machine.

[0046] Figure 1 is a schematic structural diagram of a packaging machine according to an embodiment of the present invention. As shown in Figure 1, and referring to Figures 2 and 3, this embodiment of the present invention provides a packaging machine 100, including a frame 110, a first conveyor belt 210, a second conveyor belt 220, a guide member 30, and a feeding mechanism 40. The first conveyor belt 210 is disposed on the frame 110 and extends in a front-rear direction. The second conveyor belt 220 is disposed on the frame 110 and extends in a front-rear direction. The rear end of the first conveyor belt 210 is located in front of the front end of the second conveyor belt 220, and the first conveyor belt 210 and the second conveyor belt 220 are staggered left and right. A guide member 30 is mounted on the frame 110, forming a guide channel 310 extending in the front-to-back direction. The guide channel 310 is located at the rear end of the first conveyor belt 210, and is positioned opposite to the first conveyor belt 210. The bottom wall of the guide channel 310 is on the same plane as the upper surface of the first conveyor belt 210, so that the box tray 520 on the conveyor belt is conveyed backward along the guide channel 310. The front end of the guide channel 310 narrows from front to back. A pushing mechanism 40 is mounted on the frame 110, and is configured to push the box tray 520 conveyed from the guide channel 310 onto the second conveyor belt 220.

[0047] In this embodiment, the packaging machine 100 includes a frame 110, a first conveyor belt 210, a second conveyor belt 220, a guide member 30, and a pushing mechanism 40. Both the first conveyor belt 210 and the second conveyor belt 220 extend in a front-to-back direction and are staggered left and right. A guide member 30 is provided at the rear of the first conveyor belt 210. When the packaging machine 100 is operating, the box tray 520 is conveyed from front to rear by the first conveyor belt 210, entering the guide channel 310 from the rear end of the first conveyor belt 210. The box tray 520 within the guide channel 310 moves backward along the guide channel 310 under the pushing action of other box trays 520 in front. When the box tray 520 moves to one side of the pushing mechanism 40, the pushing mechanism 40 pushes the box tray 520 towards the second conveyor belt 220. A guide member 30 is provided at the rear of the first conveyor belt 210, and the guide member 30 has a guide channel 310 within it. The box tray 520 enters the guide channel 310 through the inlet at the front end of the guide channel 310. Due to the wide inlet of the guide channel 310, even if the box tray 520 deviates on the first conveyor belt 210, it can still enter the guide channel 310. The box tray 520 is conveyed backward along the guide channel 310, and the width of the guide channel 310 gradually decreases. The walls on both sides of the guide channel 310 contact the box tray 520 to organize it, making the box tray 520 neatly arranged. The gradually narrowing front end of the guide channel 310 ensures that the box tray 520, which may deviate during the conveying process, is neatly arranged, preventing the box tray 520 from getting stuck on the packaging machine 100 when the pushing mechanism 40 pushes it, thereby preventing damage to the box tray 520 or the packaging machine 100.

[0048] In some embodiments of this utility model, as shown in Figures 1 and 2, the guide member 30 includes a first guide plate 321 and a second guide plate 331. The first guide plate 321 is vertically arranged. The second guide plate 331 is vertically arranged and disposed on the side of the first guide plate 321 away from the second conveyor belt 220. The second guide plate 331 is disposed opposite to the first guide plate 321 to form a guide channel 310 between the first guide plate 321 and the second guide plate 331. The front end of the first guide plate 321 has a first inclined plate 322, which is inclined from front to back in a direction away from the second conveyor belt 220. The second guide plate 331 has a second inclined plate 332, which is inclined from front to back in a direction closer to the second conveyor belt 220.

[0049] In this embodiment, the guide member 30 includes a first guide plate 321 and a second guide plate 331 disposed opposite to each other. The front end of the first guide plate 321 has a first inclined plate 322, and the front end of the second guide plate 331 has a second inclined plate 332. A reduced section at the front end of the guide channel 310 is formed between the first inclined plate 322 and the second inclined plate 332. The guide channel 310 formed between the first guide plate 321 and the second guide plate 331 allows the box holder 520 to pass through. The guide member 30 has a simple structure and is easy to manufacture and install.

[0050] In some embodiments of this utility model, as shown in FIG2, the rear end of the first guide plate 321 also has a guide surface 323 that bends toward the direction away from the second conveyor belt 220, and the end of the guide surface 323 is tangent to a vertical plane extending in the left-right direction.

[0051] In this embodiment, the rear end of the first guide plate 321 has a curved guide surface 323, the end of which is tangent to a vertical plane extending in the left-right direction. After the box tray 520 is conveyed out of the guide channel 310, it is pushed by the pushing mechanism 40 towards the second conveyor belt 220, that is, the box tray 520 is pushed to move in the left-right direction. The end of the guide surface 323 is tangent to the vertical plane extending in the left-right direction. When the box tray 520 moves towards the second conveyor belt 220, the guide surface 323 guides the box tray 520 to move in the left-right direction, preventing the box tray 520 from shifting when the pushing mechanism 40 pushes the box tray 520, avoiding the box tray 520 from getting stuck on the packaging machine 100, thereby reducing the risk of damage to the box tray 520 and the packaging machine 100.

[0052] In some embodiments of this utility model, as shown in FIG2, the pushing mechanism 40 is located on the side of the second conveyor belt 220 closer to the first conveyor belt 210. The pushing mechanism 40 includes a driving mechanism 410, a push plate 420, a baffle, and a reinforcing plate 440. The driving mechanism 410 is fixedly mounted on the frame 110 and has an output end that extends and retracts in the left-right direction. The output end is located on the side of the driving mechanism 410 closer to the second conveyor belt 220. The push plate 420 is fixedly mounted on the output end and is vertically arranged. The baffle is connected to the push plate 420 and extends in the left-right direction. Two adjacent sides of the reinforcing plate 440 are respectively connected to the push plate 420 and the baffle.

[0053] In this embodiment, the feeding mechanism 40 includes a drive mechanism 410, a push plate 420, a baffle, and a reinforcing plate 440. The drive mechanism 410 is mounted on the frame 110. The push plate 420 is connected to the output end of the drive mechanism 410 near the second conveyor belt 220. The baffle is connected to the side of the push plate 420 near the first conveyor belt 210, and the baffle is perpendicular to the push plate 420. The reinforcing plate 440 is connected above the push plate 420 and the baffle. When the feeding mechanism 40 is working, the drive mechanism 410 drives the output end to move toward the second conveyor belt 220, thereby causing the push plate 420 to push the tray 520 toward the second conveyor belt 220. The baffle extends in the left and right direction. When it moves with the push plate 420 to the second conveyor belt 220, the baffle blocks the front box tray 520 from moving backward, preventing multiple box trays 520 from squeezing and affecting the operation of the pusher mechanism 40, improving the stability of the pusher mechanism 40, and thus preventing the box tray 520 from getting stuck on the packaging machine 100, improving the stability of the packaging machine 100, and preventing damage to the box tray 520 or the packaging machine 100.

[0054] Furthermore, the two adjacent edges of the reinforcing plate 440 are respectively connected to the push plate 420 and the baffle to prevent the push plate 420 and the baffle from shaking or bending, thereby improving the structural stability of the pushing mechanism 40, and thus preventing the box tray 520 from getting stuck on the packaging machine 100, further improving the stability of the operation of the packaging machine 100, and preventing damage to the box tray 520 or the packaging machine 100.

[0055] In some embodiments of this utility model, the drive mechanism 410 is a cylinder or a single-axis robot.

[0056] In some embodiments of this utility model, as shown in FIG1, the projection portion of the guide member 30 on the horizontal plane is located on the first conveyor belt 210. The guide member 30 and the first conveyor belt 210 are spaced apart.

[0057] In this embodiment, the front end of the guide member 30 is positioned above the first conveyor belt 210. That is, the inlet of the guide channel 310 is positioned above the rear end of the first conveyor belt 210, and the box tray 520 directly enters the guide channel 310 from the rear end of the first conveyor belt 210. The connection is relatively tight, preventing the box tray 520 from shifting due to the gap between the first conveyor belt 210 and the guide channel 310. This avoids the box tray 520 shifting and getting stuck in the packaging machine 100, thereby improving the stability of the packaging machine 100's operation and preventing damage to the box tray 520 or the packaging machine 100.

[0058] In some embodiments of this utility model, as shown in FIG2, the packaging machine 100 further includes a mounting plate 121 and a pushing area 122, with the guide member and the pushing mechanism 40 fixed on the mounting plate 121. The mounting plate 121, located behind the guide member 30, forms the pushing area 122, which is situated between the pushing mechanism 40 and the second conveyor belt 220. The pushing area 122 is provided with a guide groove 123, the bottom wall of which slopes downward toward the second conveyor belt 220, and the bottom of the guide groove 123 on the side closest to the second conveyor belt 220 is flush with the upper surface of the second conveyor belt 220.

[0059] In this embodiment, the pushing area 122 is provided with a guide groove 123, and the end of the guide groove 123 near the pushing mechanism 40 is higher than the end near the second conveyor belt 220. When the pushing mechanism 40 pushes the box tray 520 to the second conveyor belt 220, the box tray 520 moves along the guide groove 123 and is sandwiched between the two side walls of the guide groove 123 to prevent the box tray 520 from deviating during the pushing process, thereby ensuring that the box tray 520 is stably pushed to the second conveyor belt 220.

[0060] Furthermore, the bottom of the guide groove 123 is inclined downward, which is more conducive to the movement of the box holder 520, reduces friction during movement, and prevents damage to the box holder 520.

[0061] In some other embodiments of the present invention, the bottom of the guide groove 123 on the side near the second conveyor belt 220 is higher than the upper surface of the second conveyor belt 220.

[0062] In some embodiments of this utility model, as shown in FIG1, a feeding bin 510 is provided on the second conveyor belt 220, and the feeding bin 510 is arranged opposite to the pushing mechanism 40. The packaging machine 100 also includes a positioning plate 60, which is vertically arranged on the frame 110 and extends to the left and right. The front surface of the positioning plate 60 is on the same plane as the rear wall of the bin.

[0063] In this embodiment, the packaging machine 100 also includes a positioning plate 60, which extends in the left-right direction. The front surface of the positioning plate 60 is on the same plane as the rear wall of the hopper. After the box tray 520 is conveyed out from the guide channel 310, it moves backward under the squeezing action of the front box tray 520 until the rear wall of the last box tray 520 contacts the front surface of the positioning plate 60. The positioning plate 60 plays a positioning role. After each box tray 520 moves to a fixed position, it is pushed onto the second conveyor belt 220 by the pushing mechanism 40. This facilitates the pushing of the box tray 520, prevents the box tray 520 from shifting and causing the pushing mechanism 40 to be unable to push the box tray 520 onto the second conveyor belt 220, avoids the box tray 520 getting stuck on the packaging machine 100, improves the stability of the packaging machine 100 operation, and prevents damage to the box tray 520 or the packaging machine 100.

[0064] Furthermore, the positioning plate 60 extends in the left and right direction, so even if the box tray 520 is offset before being pushed, it can be straightened by the mutual squeezing action of the front box tray 520 and the positioning plate 60, further preventing the box tray 520 from getting stuck on the packaging machine 100, improving the stability of the packaging machine 100 operation, and preventing damage to the box tray 520 or the packaging machine 100.

[0065] In some embodiments of this utility model, the second conveyor belt 220 is provided with a plurality of hoppers for accommodating the box trays 520. As the second conveyor belt 220 conveys, the position of the hoppers also moves. When the hopper moves to a position corresponding to the pushing mechanism 40, the hopper becomes the feeding hopper 510.

[0066] In some other embodiments of the present invention, the front surface of the positioning plate 60 is arranged parallel to the rear wall surface of the hopper, and the front surface of the positioning plate 60 is located in front of the rear wall surface of the hopper.

[0067] In this embodiment, the front surface of the positioning plate 60 is located in front of the rear wall of the hopper. Since the box tray 520 has a right angle, even when the front surface of the positioning plate 60 and the rear wall of the hopper are on the same plane, the corner of the box tray 520 may get stuck on the side of the rear wall of the feeding hopper 510. With the front surface of the positioning plate 60 in front of the rear wall of the feeding hopper 510, there is a certain gap between the box tray 520 and the rear wall of the feeding hopper 510 when the box tray 520 enters the feeding hopper 510, preventing the box tray 520 from contacting the feeding hopper 510 and avoiding it getting stuck, thus preventing damage to the box tray 520 or the packaging machine 100. Furthermore, the lack of contact between the box tray 520 and the feeding hopper 510 reduces friction between them, which is more conducive to the conveying of the box tray 520.

[0068] In some embodiments of this utility model, as shown in FIG1, the packaging machine 100 further includes a third guide plate 710, which is vertically disposed on the frame 110. The third guide plate 710 is located on the side of the second conveyor belt 220 near the pushing mechanism 40 and behind the positioning plate 60. The front end of the third guide plate 710 has a third inclined plate 720, which is inclined from front to back towards the second conveyor belt 220.

[0069] In this embodiment, the packaging machine 100 further includes a third guide plate 710, which is disposed on one side of the second conveyor belt 220 and located behind the positioning plate 60. The front end of the third guide plate 710 has a third inclined plate 720, which is inclined from front to back towards the second conveyor belt 220. When the box tray 520 is pushed onto the second conveyor belt 220 by the pushing mechanism 40, the second conveyor belt 220 conveys the box tray 520 backward. Even if the box tray 520 is not fully pushed into position during conveying, it will first contact the third inclined plate 720. The surfaces of the box tray 520 and the third inclined plate 720 interact, thereby pushing the box tray 520 away from the pushing mechanism 40. The third inclined plate 720 can adjust the position of the box tray 520, so as to prevent the box tray 520 from being squeezed and damaged by the frame 110 on the side of the second conveyor belt 220 during the conveying process if the box tray 520 is not pushed into place, or to prevent the box tray 520 from falling out of the feed hopper 510 during the conveying process, thereby improving the packaging efficiency of the packaging machine 100.

[0070] In some embodiments of this utility model, as shown in FIG1, the packaging machine 100 further includes a first sensing device 810, which is used to detect whether there is a box tray 520 in the pushing area 122. The pushing mechanism 40 is configured such that when the first sensing device 810 senses that there is a box tray 520 in the pushing area 122, the pushing mechanism 40 pushes the box tray 520 into the feeding bin 510.

[0071] In this embodiment, the packaging machine 100 also includes a first sensing device 810. The area between the pushing mechanism 40 and the second conveyor belt 220 is the pushing area 122. When the packaging machine 100 is working, the first sensing device 810 senses whether there is a box tray 520 in the pushing area 122. If there is a box tray 520, the pushing mechanism 40 pushes the box tray 520 towards the feeding bin 510. If there is no box tray 520 in the pushing area 122, the pushing mechanism 40 does not push the box tray. By controlling the operation of the pushing mechanism 40 with the information obtained by the first sensing device 810, the packaging machine 100 can avoid malfunctions in some mechanisms while other mechanisms continue to operate, thereby improving the automation and packaging efficiency of the packaging machine 100.

[0072] In some embodiments of this utility model, as shown in FIG1, the packaging machine 100 further includes a second sensing device 820, which is used to detect whether there is a box tray 520 in the feeding bin 510. The pushing mechanism 40 is configured such that when the second sensing device 820 senses that there is a box tray 520 in the pushing area 122, the pushing mechanism 40 stops pushing the box tray 520.

[0073] In this embodiment, the packaging machine 100 also includes a second sensing device 820. When the packaging machine 100 is working, the second sensing device 820 senses whether there is a box tray 520 in the feeding bin 510. If there is a box tray 520, it means that the second conveyor belt 220 has not delivered the box tray 520 in time. The pushing mechanism 40 pauses the pushing mechanism of the box tray 520 and resumes the pushing action after the box tray 520 is delivered. By setting the information obtained by the second sensing device 820 to control the action of the pushing mechanism 40, it is possible to avoid the packaging machine 100 from malfunctioning in some mechanisms while other mechanisms continue to operate, and to prevent multiple box trays 520 from being pushed into one feeding bin 510 and causing the box trays 520 to be crushed. This improves the automation of the packaging machine 100 and increases the packaging efficiency of the packaging machine 100.

[0074] In some embodiments of this utility model, as shown in FIG1, the packaging machine 100 further includes a first sensing device 810 and a second sensing device 820. The first sensing device 810 is used to detect whether there is a box tray 520 in the pushing area 122. The pushing mechanism 40 is configured such that when the first sensing device 810 senses that there is a box tray 520 in the pushing area 122, the pushing mechanism 40 pushes the box tray 520 into the feeding bin 510. The second sensing device 820 is used to detect whether there is a box tray 520 in the feeding bin 510. The pushing mechanism 40 is configured such that when the second sensing device 820 senses that there is a box tray 520 in the pushing area 122, the pushing mechanism 40 stops pushing the box tray 520.

[0075] In some embodiments of this utility model, as shown in FIG3, the packaging machine 100 further includes at least two folding mechanisms 90 and at least two third conveyor belts 230. The folding mechanisms 90 are used to fold the box trays 520. The third conveyor belts 230 are arranged in a one-to-one correspondence with the folding mechanisms 90. The front end of the third conveyor belt 230 is connected to the discharge end of the folding mechanism 90, and the rear end of the third conveyor belt 230 is arranged opposite to the first conveyor belt 210, so that the box trays 520 on the third conveyor belt 230 are conveyed to the first conveyor belt 210.

[0076] In this embodiment, the packaging machine 100 further includes a folding mechanism 90 and a third conveyor belt 230. The folding mechanism 90 folds the box tray 520 and places it on the third conveyor belt 230, which then conveys the box tray 520 to the first conveyor belt 210. On the first conveyor belt 210, eye patches are placed into the box tray 520 manually or by machine, and the pushing mechanism 40 then pushes the box tray 520 along with the eye patches onto the second conveyor belt 220. The folding and conveying of the box tray 520 are automated, improving the automation of the packaging machine 100, saving labor and time, and increasing the packaging efficiency of the packaging machine 100.

[0077] In other embodiments of this invention, the first conveyor belt 210 and the second conveyor belt 220 can also be used to convey packaging boxes or other packaged items. Accordingly, the folding mechanism 90 can also be used for folding packaging boxes or other packaged items, and the third conveyor belt 230 can also be used to convey packaging boxes or other packaged items.

[0078] In some embodiments of this utility model, the packaging machine 100 can be used for packaging eye patches, or for packaging other products.
