Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, and particularly relates to a bag-opening device for a self-standing side-suction nozzle packaging bag of a bag-type packaging machine. Background Art

[0002] Packaging products on the market now, such as granular seasonings, white granulated sugar, etc., have the packaging bags made in the style of self-standing side-suction nozzles. The self-standing design is to enable the packaging bag to stand on the table or storage rack after the product is used up, which is convenient for placement and taking; for the side-suction nozzle, after unscrewing the cover of the suction nozzle, it is convenient to pour out the product from the suction nozzle, and then screw the cover of the suction nozzle after use to facilitate storage and sealing.

[0003] Since a suction nozzle is added to the bag-opening top end of the self-standing side-suction nozzle packaging bag, the filling port is too small and the filling speed is slow. In order to improve the filling efficiency, it is mostly filled from the self-standing end at the bottom. However, this will cause a problem. The self-standing end is a four-layer packaging bag. When making the bag, three layers are glued together to form a self-standing bottom, and a single side is left for bag opening and filling. In this way, ordinary bag opening is likely to suck open the pre-made self-standing bottom. When feeding, when the funnel presses on the three-layer edge of the self-standing bottom, it will cause material scattering, or some materials will fall into the sandwich of the three-layer self-standing part, resulting in poor sealing and clamping during sealing, directly causing low packaging output and high packaging waste.

[0020] Such as Figure 1-2As shown in the figure, the present utility model provides a technical solution: a bag-feeding type packaging machine self-standing side suction nozzle bag opening device, which includes a transmission mechanism, a main support mechanism, and an upper execution mechanism. The transmission mechanism includes a main shaft 54, and a cam 53 is fixedly installed on the outer side of the main shaft 54. The main shaft 54 is connected to the main motor of the equipment. The cam 53 is clamped on the main shaft 54 by bolts. The high and low point strokes and angles of the main shaft 54 control when the bag opening device closes and when it opens. There is a fitting rolling bearing 51 on the surface of the main shaft 54. The rolling bearing 51 is connected to a rocker 50 through a bearing shaft 52. A support shaft 55 is rotatably installed on the rocker 50. A copper sleeve is movably installed between the rocker 50 and the support shaft 55 to ensure that the rocker 50 rotates flexibly on the support shaft 55. Limit sleeves 56 are installed on both sides of the rocker 50 to limit the position of the rocker 50. An internal thread spherical plain bearing 60 is installed at the top of the rocker 50. This spherical plain bearing 60 has a right-hand thread. The joint of the spherical plain bearing 60 is connected to the rocker 50 through bolts. A pull rod 61 is installed in the threaded inner hole of the spherical plain bearing 60. The pull rod 61 has a right-hand and left-hand thread. The left-hand thread end of the pull rod 61 is installed with a left-hand internal thread spherical plain bearing 62. In this way, the pull rod 61 and the internal thread spherical plain bearings 60 and the first bearing 62 at both ends form a connecting rod that can move flexibly at both ends. The spherical plain bearing 62 is installed with a driving clamp block 63 through bolts;

[0021] The main support mechanism includes a support column 1 and a transmission shaft 2. The support column 1 is fixed on the frame. Third bearings 20 are installed at both ends of the support column 1 to play a supporting role and make the transmission shaft 2 rotate flexibly. The transmission shaft 2 passes through the core of the support column 1 and is installed together with the support column 1 through the third bearings 20 at both ends. A driving clamp block 63 is installed at the lower end of the transmission shaft 2. The driving clamp block 63 is clamped on the transmission shaft 2 by bolts. A support seat 102 is installed at the top of the support column 1. The upper end of the transmission shaft 2 passes through the support seat 102. A swing rod 105 is installed at the top of the transmission shaft 2. The swing rod 105 is connected to the transmission shaft 2 through a setscrew;

[0022] Upper actuator. The upper actuator includes a support base 102 and a straight-open bag suction pipe 14. The support base 102 symmetrically mounts two guide rails 103 along the center. A slidable slider 104 is mounted on the guide rails 103. There are two sliders 104. A second fixed arm 10 is mounted on one of the sliders 104. A cylinder fixing seat 11 is mounted at the outer bottom end of the second fixed arm 10. The connection between the cylinder fixing seat 11 and the second fixed arm 10 is an elongated hole. The cylinder fixing seat 11 has a threaded hole and is connected by a bolt. The cylinder fixing seat 11 can be adjusted back and forth along the elongated hole. An auxiliary cylinder 12 is mounted at the bottom end of the cylinder fixing seat 11. A suction pipe fixing plate 13 is mounted at the front end of the auxiliary cylinder 12. The straight-open bag suction pipe 14 is mounted on the suction pipe fixing plate 13. An opening bag suction cup 6 is mounted at the front end of the straight-open bag suction pipe 14. A first fixed arm 7 is mounted on the other slider 104. A fixed rod 3 is mounted at the front end of the first fixed arm 7. Two fixed blocks 5 are mounted at the other end of the fixed rod 3. An air suction pipe 4 is mounted on the fixed blocks 5. A suction cup 6 is mounted at the front end of the air suction pipe 4. A connecting plate 106 is mounted at the slider 104 of the first fixed arm 7 and the second fixed arm 10. Second bearings 107 are mounted in two holes of the connecting plate 106. One hole of the connecting plate 106 and the first fixed arm 7 and the second fixed arm 10 are connected together by a bolt. The other hole is fixed to the two end holes of a swing rod 105 by a bolt. In this way, the cam 53 controls the movement of the rocker 50.

[0023] Working principle: The rocker 50 controls the rotation of the transmission shaft 2 through a connecting rod composed of a pull rod 61, a joint bearing 60 and a first bearing 62, and a driving clamp block 63 fixed on the transmission shaft 2. The transmission shaft 2 controls the first fixed arm 7 and the second fixed arm 10 seat to perform linear motion through a swing rod 105, a connecting plate 106, a guide rail 103 and a slider 104 fixed at the top end. Finally, the opening bag suction cup 6 is closed to suck the bag. When the suction cup 6 separates, the bag mouth is sucked open. Due to the addition of a suction nozzle at the opening top end of the self-standing side-suction nozzle packaging bag, the filling port is too small and the filling speed is slow. In order to improve the filling efficiency, it is mostly filled from the bottom self-standing end. In this way, a problem will occur. The self-standing end is a four-layer packaging bag. When making the bag, three layers are glued together to form a self-standing bottom, leaving a single-sided opening for filling. In this way, ordinary bag opening is very easy to suck open the pre-made self-standing bottom. When feeding, when the funnel presses on the three-layer edge of the self-standing bottom, it will cause material scattering, or some materials will fall into the interlayer of the three-layer self-standing part, resulting in poor sealing and clamping of the seal. Therefore, an auxiliary cylinder 12 is specially added. Before opening the bag, the shaft of the auxiliary cylinder 12 extends out, folds the three-layer edge of the packaging bag, plays a shaping role, and then the shaft of the auxiliary cylinder 12 returns, pulls out the single side, and then the two suction cups 6 are opened with the action of the cam 53 to complete the entire bag opening action, ensuring the filling qualification rate, high bag opening efficiency and high qualification rate, not affecting the packaging speed, avoiding the packaging material loss caused by poor bag opening, and reducing the production cost.
