Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing of the bag opening of an aluminum foil bag, in particular to an automatic sealing machine for the bag opening of an aluminum foil bag. Background Art

[0002] Aluminum foil bag 1 is used to package tablets, and its structure is as follows Figure 1 As shown, it includes a bag body 2 and a bag opening 3, the bag opening 3 is connected to the bag body 2, and the bag opening 3 is located at the upper end of the bag body 2. After the worker fills the tablets into the bag body 2 from the bag opening 3, the worker needs to use a heat sealer to seal the bag opening 3 of the aluminum foil bag.

[0003] The heat sealing machine used in a certain workshop includes a workbench, a bracket fixed on the workbench, and a lifting cylinder fixed on the bracket. A hot pressing plate is fixed on the active end of the piston rod of the lifting cylinder. The hot pressing plate is arranged directly above the workbench. The terminal of the hot pressing plate is connected to a power supply. The power supply energizes the hot pressing plate, and heat is generated on the hot pressing plate.

[0004] The method by which the heat sealer seals the bag opening 3 of the aluminum foil bag is as follows:

[0005] S1. A worker takes out an aluminum foil bag 1 filled with tablets, places the bag body 2 of the aluminum foil bag 1 flat on the workbench, and places the bag opening 3 flat on the workbench downward, while ensuring that the bag opening 3 is directly below the hot pressing plate;

[0006] S2, the piston rod of the control lifting cylinder extends downward, the piston rod drives the hot pressing plate to move downward, the hot pressing plate presses the bag opening 3 on the workbench, and after maintaining the pressure for a period of time, the bag opening of the aluminum foil bag 1 can be heat-sealed;

[0007] S3, after sealing, the worker throws the aluminum foil bag 1 with the bag opening 3 sealed into the material basket;

[0008] S4. Repeat the operations of steps S1 to S3 to continuously throw a plurality of aluminum foil bags 1 with sealed bag openings 3 into the material basket.

[0009] However, although this heat sealer can heat seal the bag opening 3 of the aluminum foil bag 1, it still has the following technical defects:

[0010] I. In step S1, after the worker places the bag body 2 of the aluminum foil bag 1 flat on the workbench, it is necessary to manually frequently adjust the position of the bag body 2 so that the bag opening 3 is directly below the hot pressing plate. Frequent position adjustment undoubtedly increases the heat-sealing time of the bag opening 3 of the aluminum foil bag 1, thereby reducing the heat-sealing efficiency of the bag opening of the aluminum foil bag 1.

[0011] II. When the basket is full of aluminum foil bags 1, it is necessary to manually replace the empty basket with a new one. However, the manual replacement of the empty basket with a new one is slow, thereby prolonging the heat sealing time of subsequent aluminum foil bags (because heat sealing can only continue after replacement). Therefore, there is a technical defect of low heat sealing efficiency.

[0012] Therefore, there is an urgent need for an automatic sealing machine that greatly improves the heat-sealing efficiency of the aluminum foil bag mouth. Utility Model Content

[0013] The utility model aims to overcome the shortcomings of the prior art and provide an automatic sealing machine for the bag opening of an aluminum foil bag which has a compact structure, greatly improves the heat-sealing efficiency of the bag opening of an aluminum foil bag, and has a high degree of automation.

[0015] The belt conveyor A located on the upper side includes a driving motor A fixedly mounted on the rear end surface of the vertical plate, a driving pulley A and a driven pulley A rotatably mounted on the front end surface of the vertical plate, a heat-resistant belt is installed between the driving pulley A and the driven pulley A, and the output shaft of the driving motor A is connected to the driving pulley A;

[0016] Two electric heating plates are fixedly arranged on the front end surface of the vertical plate, one of which is located in the heat-resistant belt of the upper belt conveyor A, and the other is located in the heat-resistant belt of the lower belt conveyor A;

[0017] A roller conveyor fixed on a pad is arranged directly below the flat belt conveying mechanism, and a material blocking electric cylinder fixed on the pad is arranged directly below the roller conveyor. The piston rod of the material blocking electric cylinder extends upward above the roller conveyor, and a baffle is fixed on the extended end.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings, and the protection scope of the utility model is not limited to the following:

[0030] The belt conveyor A7 located on the upper side includes a driving motor A9 fixedly mounted on the rear end surface of the vertical plate 6, a driving pulley A10 and a driven pulley A11 rotatably mounted on the front end surface of the vertical plate 6, a heat-resistant belt 12 is installed between the driving pulley A10 and the driven pulley A11, and the output shaft of the driving motor A9 is connected to the driving pulley A10; two electric heating plates 13 are fixedly mounted on the front end surface of the vertical plate 6, and the connection terminals of the two electric heating plates 13 are connected to a power source, one of the electric heating plates 13 is located in the heat-resistant belt 12 of the belt conveyor A7 on the upper side, and the other electric heating plate 13 is located in the heat-resistant belt 12 of the belt conveyor A7 on the lower side;

[0031] A roller conveyor 14 fixed on the pad 4 is arranged directly below the flat belt conveying mechanism 5. The roller conveyor 14 is in a closed state in the initial state. A material blocking electric cylinder 15 fixed on the pad 4 is arranged directly below the roller conveyor 14. The piston rod of the material blocking electric cylinder 15 extends upward above the roller conveyor 14, and a baffle 16 is fixed on the extended end. A plurality of material baskets 17 placed on the roller of the roller conveyor 14 are sequentially abutted against the right side of the baffle 16.

[0032] The belt conveyor B8 includes a driving motor B18 fixedly mounted on the rear end surface of the vertical plate 6, a driving pulley B19 and a driven pulley B20 rotatably mounted on the front end surface of the vertical plate 6, a belt 21 is installed between the driving pulley B19 and the driven pulley B20, and the output shaft of the driving motor B18 is connected to the driving pulley B19.

[0033] The sealing machine also includes a controller, which is electrically connected to the material blocking electric cylinder 15, the drive motor A9 and the drive motor B18 via a signal line. The worker can control the piston rod of the material blocking electric cylinder 15 to extend or retract through the controller, and can also control the start or shut down of the drive motor A9 and the drive motor B18, which facilitates the worker's operation and has the characteristics of a high degree of automation.

[0034] The working process of the utility model is as follows:

[0035] S1. Turn on the driving motors B18 of the two belt conveyors B8. The driving motors B18 drive the driving pulleys B19 to rotate. The driving pulleys B19 drive the belt 21 to rotate. The belt 21 of the upper belt conveyor B8 rotates clockwise, while the belt 21 of the lower belt conveyor B8 rotates counterclockwise.

[0036] S2, turn on the drive motors A9 of the two belt conveyors A7, the drive motor A9 drives the active pulley A10 to rotate, and the active pulley A10 drives the heat-resistant belt 12 to rotate, wherein the heat-resistant belt 12 of the upper belt conveyor A7 rotates clockwise, and the heat-resistant belt 12 of the lower belt conveyor A7 rotates counterclockwise;

[0037] S3, open the flat belt conveying mechanism 5, and the flat belt 22 of the flat belt conveying mechanism 5 rotates counterclockwise;

[0038] S4, turn on the power supply, the power supply energizes the two electric heating plates 13, both electric heating plates 13 generate heat, and the heat is transferred to the heat-resistant belt 12;

[0039] S5, the worker takes out a Figure 1 The aluminum foil bag 1 shown in the figure, the bag body 2 of the aluminum foil bag 1 is placed flat on the flat belt 22 of the flat belt conveyor mechanism 5, as shown in the figure. Figure 4 As shown, the bag opening 3 of the aluminum foil bag 1 is horizontally embedded between the two heat-resistant belts 12, as shown in FIG. Figure 4 As shown, the flat belt 22 transports the bag body 2 of the aluminum foil bag 1 from right to left, and at the same time, the two heat-resistant belts 12 transport the bag opening 3 of the aluminum foil bag 1 from right to left, and the heat-resistant belts 12 heat the bag opening 3;

[0040] S6, when the bag opening 3 of the aluminum foil bag 1 moves between the two belts 21, the two belts 21 squeeze the bag opening 3, and under the squeezing effect, the bag opening 3 of the aluminum foil bag 1 is closed, thereby achieving heat sealing of the bag opening 3; then the bag opening 3 of the aluminum foil bag 1 escapes from the left end of the two belts 21, and after escaping, the flat belt 22 continues to transport the sealed aluminum foil bag 1 to the left until the aluminum foil bag 1 falls into the leftmost material basket 17, and the falling direction of the aluminum foil bag 1 is as follows Figure 4 As indicated by the hollow arrow;

[0041] S7, the worker repeats the operations of steps S5 to S6 to continuously heat-seal the bag openings 3 of multiple aluminum foil bags 1, and collects the sealed aluminum foil bags 1 in the leftmost material basket 17;

[0042] Among them, from steps S5 to S6, it can be seen that the worker only needs to place the bag body 2 of the aluminum foil bag 1 flat on the flat belt 22, and at the same time, embed the bag opening 3 of the aluminum foil bag 1 between the two heat-resistant belts 12, and then the flat belt 22 transports the bag body 2 to the left, and at the same time, the heat-resistant belt 12 transports the bag opening 3 to the left, and the heat-resistant belt 12 heats the bag opening 3, and then when the bag opening 3 enters between the two belts 21, the two belts 21 squeeze the heated bag opening 3, thereby realizing automatic heat sealing of the bag opening 3 of the aluminum foil bag 1. It can be seen that compared with the heat sealing machine used in the workshop, the sealing machine does not require the worker to frequently adjust the position of the bag body 2 so that the bag opening 3 is positioned directly below the hot pressing plate, thereby greatly shortening the heat sealing time of the bag opening 3 of the aluminum foil bag 1, and then greatly improving the heat sealing efficiency of the bag opening 3 of the aluminum foil bag 1.

[0043] S8. When the leftmost basket 17 is full of aluminum foil bags 1, the worker controls the piston rod of the material blocking electric cylinder 15 to retract downward, and the piston rod drives the baffle 16 to move downward. Figure 5As shown, the worker takes the basket 17 away from the roller conveyor 14 in the direction of Figure 5 As shown by the solid arrow in the middle; after taking it away, the piston rod of the material blocking electric cylinder 15 is controlled to extend upward to reset the baffle 16. After resetting, the roller conveyor 14 is controlled to start, and the roller conveyor 14 conveys the subsequent empty material basket 17 to the left until the empty material basket 17 is blocked by the baffle 16, thereby realizing the rapid replacement of the empty material basket 17.

[0044] Among them, it can be seen from step S8 that only by controlling the actions of the material blocking electric cylinder 15 and the roller conveyor 14, the subsequent empty material basket 17 can be quickly transported to the material receiving station without manual replacement of the empty material basket 17, and the heat sealing time of the subsequent aluminum foil bag will not be extended, thereby further improving the heat sealing efficiency of the bag mouth 3 of the aluminum foil bag 1.
