DETAILED DESCRIPTION

[0015] The utility model discloses an embodiment of the utility model will be below, clear, complete, the technical scheme in the embodiment of the utility model in the embodiment of the utility model is described, obviously, the described embodiment only is a part of embodiment of the utility model, instead of all the embodiment;Based on the embodiment in the utility model, all other embodiments that the ordinary skill in the art obtains without making creative labor are within the scope of the utility model protection.

[0016] By Figs. 1-3 Give, the utility model includes device main body 1 and sealing machine body 2, and the both sides of device main body 1 are penetrated by import and export, and the inside of device main body 1 is provided with conveying platform 3, and the both ends of conveying platform 3 correspond to import and export respectively, and the top of conveying platform 3 is provided with positioning mechanism and sealing machine body 2, and positioning mechanism includes first support frame 4, and first support frame 4 is penetrated by first sliding slot 5, and the cross section of first sliding slot 5 is rectangle, and first sliding slot 5 is slidably connected with sliding rod 6, and the cross section height of sliding rod 6 is consistent with the height of first sliding slot 5, and the bottom of sliding rod 6 is fixedly connected with trigger rod 7, and one end of first sliding slot 5 is provided with round hole 8, and the diameter of round hole 8 is greater than the length of the diagonal line of the cross section of sliding rod 6, and one end of first support frame 4 is fixedly connected with second support frame 9, and second support frame 9 is provided with second sliding slot, and second sliding slot is provided with screw rod 10, and gear 13 is fixedly arranged in the middle of screw rod 10, and the thread on the both sides of gear 13 is opposite, and rack 11 is arranged in first sliding slot 5, and one end of rack 11 is fixedly connected with connecting ring 12, and connecting ring 12 is rotatably sleeved on sliding rod 6, and rack 11 and gear 13 are engagedly connected, and the both ends of screw rod 10 are threadedly connected with positioning mechanism respectively.

[0017] Positioning mechanism includes two positioning plates 14, and one side of two positioning plates 14 is connected with connecting block 15, and the cross section of connecting block 15 and second sliding slot is rectangle with same size, and connecting block 15 is slidably connected in second sliding slot, and connecting block 15 is threadedly sleeved on the outside of screw rod 10, and screw rod 10 can drive positioning plate 14 to approach / away from each other through connecting block 15.

[0018] Two positioning plates 14 are provided with arc surfaces at one end, and the two arc surfaces are symmetrically arranged. The arc surfaces help to provide guidance for the movement of the carton, so that the carton can smoothly enter the middle of the two positioning plates 14.

[0019] A tension spring 16 is connected between the positioning plate 14 and the connecting block 15. The tension spring 16 can provide buffering after the two positioning plates 14 clamp the carton, so as to avoid excessive contraction of the positioning plate 14 and damage to the carton.

[0020] A compression spring 17 is arranged between the sliding rod 6 and the second support frame 9. The compression spring 17 pushes the trigger lever 7 during the movement and positioning of the carton, so as to compress the compression spring 17. After the carton moves away from the positioning mechanism, the compression spring 17 is released, and the sliding rod 6 drives the trigger lever 7 to reset.

[0021] Working principle: when the carton is placed on the conveying platform 3, the carton moves forward along the conveying platform 3 and gradually enters the clamping area formed by the two positioning plates 14. During this process, as the carton continues to move forward, the carton pushes the trigger lever 7, which pushes the sliding rod 6 to move forward. The sliding rod 6 drives the rack 11 to move, thereby driving the gear 13 to rotate. The gear 13 drives the screw rod 10 to rotate, so that the threads at both ends of the screw rod 10 act on the connecting block 15, thereby driving the two positioning plates 14 to approach each other. A pushing force is provided from both sides of the carton to adjust the position of the carton, and the tension spring 16 provides buffering to avoid damaging the carton. During this process, due to the loading of the carton, there is a large friction force between the bottom surface of the carton and the conveying platform 3, which can overcome the resistance of the compression spring 17 and compress it. When the carton is adjusted and continues to move forward, the sliding rod 6 moves into the circular hole 8, and the sliding rod 6 can rotate in the circular hole 8, so that the trigger lever 7 is flipped upward. The carton can leave the positioning mechanism and then enter below the carton sealing machine body 2. The middle seam of the positioned carton is aligned with the carton sealing machine body 2 for sealing. At the same time, as the carton leaves the positioning mechanism, the compression spring 17 is released, driving the sliding rod 6 and the trigger lever 7 to reset. At the same time, the screw rod 10 is reversely rotated under the action of the gear 13, so that the positioning plates 14 move away from each other and return to the initial state, facilitating the entry of the next carton.
