Description

Technical Field

[0001] The utility model relates to a bag feeding deviation correcting mechanism. Background Art

[0002] From the current market perspective, generally all fully automatic packaging machines include a bag delivery mechanism that delivers the bag to the required station for subsequent actions such as opening the bag mouth. The common bag delivery mechanism is manually adjusted to adapt to the size of the packaging bag to ensure the smooth centering of the centering cylinder, but manual adjustment is cumbersome and has large errors; and there is currently an unlimited position mechanism at the front end that limits the position of the moving direction of the packaging bag when it is delivered to the centering station, which often results in the inability to ensure that the centering is in the appropriate position, that is, the packaging position cannot be smoothly corrected, and the coordination with the bag opening station after centering needs to be improved, and the efficiency is insufficient.

[0017] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0018] like Figures 1 to 4 As shown, a bag feeding correction mechanism comprises a bag feeding conveyor belt C1, a correction component C2 is mounted above the conveying end of the bag feeding conveyor belt, the correction component comprises a laterally extending correction plate C3, two correction cylinder mounting plates C4 symmetrically arranged on the correction plate and slidably connected thereto, the two correction cylinder mounting plates are respectively connected to two groups of screw nuts of a screw C5 with positive and negative teeth integrated so as to be driven to slide toward or away from each other, a correction cylinder C6 is arranged at the lower end of the two correction cylinder mounting plates, the piston ends of the two correction cylinders are arranged facing each other and are fixedly connected to the ends with an inverted Z-shaped brush fixing plate C7, and a correction brush C8 is fixedly arranged at the bottom end of the brush fixing plate along its longitudinal extension direction; a limit component C9 for limiting the end of the packaging bag is mounted outside the conveying end of the bag feeding conveyor belt.

[0019] In the embodiment of the utility model, sliding blocks are fixedly connected to the two deflection cylinder mounting plates, and are slidably connected to the transverse slide rails fixedly arranged on the deviation correction plate through the sliding blocks.

[0020] In the embodiment of the utility model, a longitudinal extension section C10 is fixedly provided at the bottom of the brush fixing plate, and the longitudinal extension section extends toward the side of the limiting component and extends vertically downward at the end to form a vertical shifting section C11. Since the horizontal surface of the receiving platform used to receive the output end of the conveyor belt is generally lower than the upper end surface of the conveyor belt for receiving, the vertical shifting section can be arranged so that when the packaging bag is sent to the limiting frame through the bag conveying conveyor belt, the vertical shifting section can cooperate with the correction brush to limit and align the front end of the packaging belt during the adjustment process.

[0021] In the embodiment of the utility model, the screw rod extends transversely and is divided into two sections with opposite rotation directions to connect the two correction cylinder mounting plates. The screw rod is installed on the correction plate via a bearing seat, and one end of the screw rod is driven to rotate by the correction motor C12.

[0022] In the embodiment of the utility model, conveyor belt brackets C13 supporting the bag conveyor belt are arranged on both sides, and vertical support vertical plates C14 are fixed on both sides of the correcting plate and are fixedly connected to the conveyor belt brackets, and the correcting motor is fixed on the support vertical plates.

[0023] In an embodiment of the utility model, the limiting assembly includes an I-shaped limiting frame C15, a limiting cylinder C16 is fixedly provided below the top of the limiting frame, the top piston end of the limiting cylinder is fixedly connected to a limiting connecting plate C17, the longitudinal end of the limiting connecting plate extends out of the limiting frame and is fixedly connected with a plurality of limiting plates C18 at intervals along its transverse length direction, and the limiting plates all extend vertically upward to be connected to the end of the packaging bag through their longitudinal end faces for limiting.

[0024] In the embodiment of the utility model, a guide slide plate C19 is fixedly provided on the top surface of the limit frame, and a slant plate C20 for guiding between the limit frame and the bag conveyor frame is extended obliquely downward on the side of the guide slide plate close to the bag conveyor belt. The slant plate is arranged in the same length as the bag conveyor belt in the transverse width direction. The arrangement of the slant plate can effectively prevent the conveyor belt from getting stuck between the limit frame and the bag conveyor frame or falling off in the gap.

[0025] In an embodiment of the utility model, a clearance opening C21 is provided on the top of the limiting frame away from the bag conveyor belt and on the same position as the limiting connecting plate for the subsequent bag stretching station to absorb the upper and lower layers of the packaging bag for stretching. At least one group of the clearance openings is provided and is staggered with the limiting plate.

[0026] The working principle of the embodiment of the utility model is as follows: first, the position of the correcting cylinder mounting plate is set according to the width of the packaging bag, that is, the distance between the two correcting cylinder mounting plates is synchronously reduced or increased by rotating the screw rod to adapt to packaging bags of different widths. After being transported by the bag conveyor belt, part of the packaging belt reaches the limit frame and is limited by the limit plate. Then the bag conveyor belt stops, and the two correcting cylinders are started and the correcting brushes are moved toward each other to correct the position of the packaging bag and keep it in the center. The vertical shifting section cooperates to limit and align the front end of the packaging belt. After the correction, the limit cylinder retracts to move the limit plate downward, and at the same time, the suction cup of the bag opening station absorbs the upper and lower layers of the packaging bag at the outlet, and performs transfer and subsequent bag opening actions, and the longitudinal transfer passes through the limit frame. Due to the misaligned setting of the limit plate, there will be no interference with each other.

[0027] The utility model is not limited to the above-mentioned best implementation mode. Anyone can derive other forms of bag feeding and correcting mechanisms under the inspiration of the utility model. All equivalent changes and modifications made according to the scope of the patent application of the utility model shall fall within the scope of the utility model.
