Specific implementation mode
[0015] The following further describes the present utility model with reference to the attached drawings.
[0016] As Figures 1 - 3 shown, the carton sealing mechanism 1 includes a mounting bracket 1-1. The mounting bracket 1-1 is provided with a side pressing belt 1-2. One side of the mounting bracket 1-1 is provided with a tape applicator 1-3. The mounting bracket 1-1 is installed on the flat plate 1-5 through the guide rail slider mechanism 1-4. One side of the flat plate 1-5 is installed with a side pressing cylinder 1-6. The piston rod of the side pressing cylinder 1-6 is connected to the mounting bracket 1-1. Two sets of carton sealing mechanisms 1 are symmetrically arranged. The upper pressing mechanism 2 is arranged above the carton sealing mechanism 1. A pressing cylinder 2-1 is provided below the upper pressing mechanism 2. A pressing block 2-2 is connected below the pressing cylinder 2-1.
[0017] The side pressing belts 1-2 are arranged on the upper and lower sides of the mounting bracket 1-1. As Figure 2 shown, the side pressing belts 1-2 can clamp the carton 3 in the upper and lower positions. The tape applicator 1-3 is arranged on one side between the side pressing belts 1-2, so that the side pressing belts 1-2 can clamp and convey the carton 3 within the entire bracket range.
[0018] A guide plate 1-7 is provided between the upper and lower side pressing belts 1-2. The tape applicator 1-3 protrudes from the guide plate 1-7. The guide plate 1-7 can cooperate with the side pressing belts 1-2 to press the two sides of the carton 4 tightly. The guide plate 1-7 can be inclined outward at one end of the inlet end of the carton 4 to form an outward - expanding opening, which can play a guiding role when the carton 4 enters.
[0019] The upper pressure mechanism 2 is provided with mounting plates 2-3 on the left and right sides of the forward direction of the side pressure belt 1-2, and linear bearings 2-4 are provided on the left and right sides of the mounting plate 2-3. The guide rod 2-5 passes through the linear bearings 2-4 of the mounting plates 2-3 on both sides and is fixedly connected to the vertical rod 1-8 fixed on the flat plate 1-5. The clamping cylinder 2-1 is fixed on the mounting plate 2-3, and the mounting plates 2-3 on both sides are connected to the positive and negative threaded rods 2-7 through nuts 2-6. By rotating the positive and negative threaded rods 2-7, the nuts 2-6 drive the mounting plates 2-3 to move along the guide rods 2-5, and the distance between the mounting plates 2-3 can be adjusted to adapt to the sealing of cartons 4 of different widths.
[0020] A connecting plate 2-9 is provided between the guide rods 2-5, and a clamp 2-10 is provided on the connecting plate 2-9 for clamping the guide rods 2-5 and the positive and negative threaded rods 2-7. After adjusting the distance between the clamping blocks 2-2, the clamp 2-10 locks the connecting plate 2-9 with the guide rods 2-5 to fix the position of the connecting plate 2-9, and then locks the connecting plate 2-9 with the positive and negative threaded rods 2-7 to prevent the positive and negative threaded rods 2-7 from rotating, thereby fixing the position of the mounting plate 2-3.
[0021] A hand wheel 2-8 is provided on one side of the positive and negative threaded rod 2-7. Rotating the hand wheel 2-8 can drive the positive and negative threaded rod 2-7 to rotate, and manually adjust the distance between the pressing blocks 2-2.
[0022] When the utility model is used, Figure 1 As shown, the opening of the expanded carton 4 is facing both sides, and is pushed onto the flat plate 1-5 along the guide plate 1-7, and then the pressing cylinder 2-1 of the upper pressing mechanism 2 extends, and the upper and lower parts of the carton 4 are pressed together by the pressing block 2-2, and then the side pressing cylinder 1-6 is started to push the mounting bracket 1-1 to press the carton 4 left and right, and then the side pressing belt 1-2 is started to clamp and transport the carton 3, and the tape applicator 1-3 applies tape to the carton 4, and the sealing is completed. The expanded carton is pressed and sealed without misalignment, and the side pressing belt 1-2 does not produce indentations when conveying.
[0023] When the carton 4 needs to be changed, if the side width specification is within the stroke range of the side pressure cylinder 1-6, the cylinder will automatically stop when it presses against the carton 4, so the side pressure cylinder 1-6 does not need to be replaced. When the clamping position of the clamping block 2-2 needs to be adjusted, the hand wheel 2-8 is rotated to drive the positive and negative screw rods 2-7 to rotate, and the distance between the mounting plates 2-3 can be adjusted, thereby adjusting the clamping position of the clamping block 2-2. After the adjustment is completed, all the clamps 2-10 are locked.
