[0031] The following describes in detail the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments

[0032] As Figures 1-8 shown, a disposable forming production line for double-folded bottom of medical sterilized paper bags provided by an embodiment of the present invention includes a material distribution table 1, a paper bag sorting conveyor 6, and an identification device 7. The paper bag sorting conveyor 6 is arranged on the material distribution table 1. The paper bag sorting conveyor 6 is used for transporting paper bags. The identification device 7 is arranged above the paper bag sorting conveyor 6. The identification device 7 can take pictures of the paper bags and identify the taken pictures to judge whether there are scratches on the outer surface of the paper bags, serving as an appearance inspection process before paper bag packaging

[0033] In order to accelerate the speed of the paper bags entering the paper bag loading conveyor 2, a paper bag loading conveyor 2 is arranged on one side of the paper bag sorting conveyor 6. Two side plates 3 are installed on the upper side of the paper bag loading conveyor 2. The two side plates 3 are respectively located on both sides of the upper end surface of the paper bag loading conveyor 2. The paper bag loading conveyor 2 is inclined, and the height of the paper bag loading conveyor 2 is higher than the height of the paper bag sorting conveyor 6

[0034] Specifically, in order to separate the paper bags, a feed baffle 4, a telescopic rod 5, and a paper bag transfer mechanism 15 are provided at the bottom of the paper bag loading conveyor 2. The feed baffle 4 is movably connected to the paper bag loading conveyor 2 through a rotating shaft. The feed baffle 4 is movably connected to the telescopic rod 5, and the other end of the telescopic rod 5 is movably connected to the outer wall of the paper bag loading conveyor 2. The telescopic rod 5 can drive the feed baffle 4 to rotate around the rotating shaft, enabling the feed baffle 4 to switch between an inclined state and a horizontal state. When the feed baffle 4 is in the inclined state, the feed baffle 4 blocks the paper bag loading conveyor 2, and the paper bags conveyed from the paper bag loading conveyor 2 fall onto the feed baffle 4. When the feed baffle 4 is in the horizontal state, the paper bags on the feed baffle 4 rotate under the action of gravity and are above the horizontal feed baffle 4. The paper bag transfer mechanism 15 can send the paper bags above the feed baffle 4 onto the paper bag sorting conveyor 6. Refer to Figure 1 , the paper bag sorting conveyor 6 has the ability to move left and right and up and down.

[0035] The identification device 7 performs an appearance identification on the paper bags on the paper bag sorting conveyor 6 and identifies unqualified paper bags. In order to distinguish between qualified and unqualified paper bags, a defective product sorting mechanism 8, a defective product conveyor 9, a defective product storage box 10, and a qualified product storage box 11 are provided on the sorting table 1. The defective product sorting mechanism 8 includes a first suction cup assembly 801, a first lifting mechanism 802, a first telescopic mechanism 803, and a first frame 804. The first suction cup assembly 801 is installed on the first lifting mechanism 802. The first lifting mechanism 802 is connected to the first telescopic mechanism 803. The first lifting mechanism 802 is installed at the first frame 804 provided on the sorting table 1. Specifically, a first chute is provided inside the first frame 804. A first support for support is provided at the first lifting mechanism 802. The first support is movably connected to the first chute. The defective product conveyor 9, the defective product storage box 10, and the qualified product storage box 11 are all provided on the sorting table 1.

[0036] When the first lifting mechanism 802 inside the defective product sorting mechanism 8 is activated, it can move the first suction cup assembly 801 to the paper bag. When the first suction cup assembly 801 is activated, it can suck the paper bag on the paper bag sorting conveyor 6. Then, the first telescopic mechanism 803 can push the sucked paper bag to the defective product conveyor 9. The defective product conveyor 9 is aligned with the defective product storage box 10, and can push the unqualified paper bags sucked by the first suction cup assembly 801 into the defective product storage box 10 for unified collection.

[0037] In order to sort out qualified products, a qualified product sorting mechanism 12 is provided on the material distribution table 1 for moving the qualified paper bags from the paper bag sorting conveyor 6 into the qualified product storage box 11. The structure of the qualified product sorting mechanism 12 is roughly the same as that in the unqualified product sorting mechanism 8. The first lifting mechanism 802 and the first telescopic mechanism 803 in the unqualified product sorting mechanism 8 can both adopt air cylinders.

[0038] Specifically, a second suction cup assembly 1201, a second lifting mechanism 1202, a second telescopic mechanism 1203, and a second frame 1204 are provided in the qualified product sorting mechanism 12. The second suction cup assembly 1201 is connected to the second lifting mechanism 1202, the second lifting mechanism 1202 is connected to the second telescopic mechanism 1203, the second telescopic mechanism 1203 is arranged on the second frame 1204, and the second frame 1204 is installed on the material distribution table 1. The qualified product sorting mechanism 12 can send the qualified paper bags recognized by the identification device 7 into the qualified product storage box 11, facilitating subsequent classification processing.

[0039] After the paper bags stored in the storage box reach a certain quantity, a new storage box needs to be replaced. In order to improve the efficiency of replacing the storage box, a storage box conveyor 13 for transporting the unqualified product storage box 10 and the qualified product storage box 11 is provided on the material distribution table 1. The traveling direction of the storage box conveyor 13 is opposite to that of the paper bag sorting conveyor 6.

[0040] In order to send the storage box away as soon as possible, a storage box discharging mechanism 14 is provided on the material distribution table 1. The storage box discharging mechanism 14 can remove the unqualified product storage box 10 and the qualified product storage box 11 filled with paper bags.

[0041] Specifically, the storage box discharging mechanism 14 includes clamping plates 1401, threaded rods 1402, clamping drive motors 1403, a clamping frame, a rack 1404, a gear 1405, an upper frame 1406, a discharging table 1409, and a lead screw 1410. There are two clamping plates 1401, and both clamping plates 1401 cooperate with the threaded rod 1402. The thread directions of the threaded rod 1402 at the positions corresponding to the two clamping plates 1401 are opposite. The lower end surface of the clamping plate 1401 is slidably connected to the clamping frame. The threaded rod 1402 cooperates with the clamping drive motor 1403. The rack 1404 is connected to the clamping frame. The rack 1404 is arranged in the upper frame 1406. The rack 1404 is connected to the gear 1405 through meshing transmission, and the gear 1405 is connected to the output end of the power motor.

[0042] More specifically, a loading and unloading hole 1407 is provided inside the upper frame 1406. The loading and unloading hole 1407 allows the storage box to pass through. A lifting power mechanism 1408 is provided at the bottom of the upper frame 1406. The lifting power mechanism 1408 can adopt a cylinder. The lifting power mechanism 1408 is arranged on the blanking table 1409. The blanking table 1409 is threadedly connected to the lead screw 1410. The blanking table 1409 abuts against the outer wall of the material distribution table 1. The lead screw 1410 is connected to a driving mechanism, and the driving mechanism can adopt a motor.

[0043] The driving mechanism can drive the lead screw 1410 to rotate, thereby driving the blanking table 1409 to move along the material distribution table 1. Components such as the lifting power mechanism 1408, gear 1405, and rack 1404 on the upper side of the blanking table 1409 cooperate with each other to send the two clamping plates 1401 to both sides of the storage box. When the clamping driving motor 1403 is started, it can drive the threaded rod 1402 to rotate, thereby driving the two clamping plates 1401 to approach each other and clamp the storage box. After that, the gear 1405 rotates, which can drive the rack 1404, clamping plate 1401, and storage box to move. The storage box can be discharged from the loading and unloading hole 1407. In this way, the blanking work of the storage box filled with paper bags is completed, which can effectively improve the sorting efficiency of paper bags.

[0044] In summary: The embodiment of the present invention provides a medical sterilization paper paper bag double-folded bottom disposable forming production line. When the first lifting mechanism 802 inside the defective product sorting mechanism 8 is started, it can move the first suction cup assembly 801 to the paper bag. When the first suction cup assembly 801 is started, it can suck the paper bag on the paper bag sorting conveyor 6. After that, the first telescopic mechanism 803 can push the sucked paper bag to the defective product conveyor 9. The defective product conveyor 9 is aligned with the defective product storage box 10, and can push the defective paper bag adsorbed by the first suction cup assembly 801 into the defective product storage box 10 for unified collection. The qualified product sorting mechanism 12 can send the qualified paper bags identified by the identification device 7 into the qualified product storage box 11, which is convenient for subsequent classification processing.

[0045] The driving mechanism can drive the lead screw 1410 to rotate, thereby driving the blanking table 1409 to move along the material distribution table 1. Components such as the lifting power mechanism 1408, gear 1405, and rack 1404 on the upper side of the blanking table 1409 cooperate with each other to send the two clamping plates 1401 to both sides of the storage box. When the clamping driving motor 1403 is started, it can drive the threaded rod 1402 to rotate, thereby driving the two clamping plates 1401 to approach each other and clamp the storage box. After that, the gear 1405 rotates, which can drive the rack 1404, clamping plate 1401, and storage box to move. The storage box can be discharged from the loading and unloading hole 1407. In this way, the blanking work of the storage box filled with paper bags is completed, which can effectively improve the sorting efficiency of paper bags.

[0046] The above are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
