Description

Technical Field

[0001] This invention relates to sealing and pasting devices in the tobacco industry, and in particular to an automatic sealing and pasting device for recycling unsealed cigarette packs. Background Technology

[0002] During production, the YB25 packaging machine experiences several issues. These include manual shutdown, seal adhesion failure, misaligned seal conveying, and malfunctions in the seal conveying mechanism. This results in a large number of unsealed cigarette packs and poorly sealed packs being rejected at the machine's exit, leading to product loss. A significant number of unsealed packs must be manually resealed by the machine operators. On average, each machine produces approximately 350 unsealed packs per shift (8 hours). Operators manually reseal these packs during production, and some packs that cannot be properly sealed are treated as defective products, resulting in substantial material waste. Furthermore, the speed at which operators manually reseal the packs varies, averaging 45 minutes for 350 packs. Manual resealing also causes significant fluctuations in the quality of the sealed packs. Additionally, operator-resealed processes hinder real-time monitoring of the equipment, creating potential quality issues. The glue application position and method differ significantly between manually resealed packs and those produced automatically, further impacting product quality. This increases the workload of operators, and the manually applied seals differ significantly from those applied to cigarette packs produced online, resulting in poor product homogeneity. Therefore, the development of an offline automatic sealing device for the YB25 packaging machine will help improve the homogeneity of cigarette products and reduce the labor intensity of workers. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic sealing device for recycling unsealed cigarette packs.

[0004] To achieve the purpose of this invention, the following technical solution is adopted:

[0005] This invention discloses an automatic label-applying device for recycling unsealed cigarette packs. It comprises: a cigarette storage compartment, a first conveyor belt frame, a first conveyor belt, a second conveyor belt, a first support, a second slide rail, a cigarette box conveyor frame, an angle control frame, an angle electric suction claw, a label feeder, a second support, a push rod, a cylinder, an operating platform, a second slider, a rotary motor, a mounting plate, a reciprocating motor, a first slide rail, a cigarette pusher plate, and a first slider. The second support is placed on one side of the first support and is higher than the first support. The first and second conveyor belts are respectively mounted on the first support, parallel to each other, with the height of the first conveyor belt higher than that of the second conveyor belt. The operating platform is fixedly supported on the first support, at a height equal to that of the second conveyor belt, and is located between the first conveyor belt, the second conveyor belt, and the second support. The cigarette storage compartment is vertically fixed to the first conveyor belt frame at one end of the first conveyor belt. Cigarette boxes are stacked inside the cigarette storage compartment. The first conveyor belt transports the bottom cigarette box from the cigarette storage compartment to the operating platform. Specifically: a pusher plate driven by a pusher cylinder is installed on the operating platform below the first conveyor belt to push cigarette boxes that fall onto the operating platform; a mounting plate is fixed on the second support on one side of the operating platform, and a crossbar spanning the first and second conveyor belts is fixed on the mounting plate below the operating platform. The first slide of the two conveyor belts has a first slider driven by a reciprocating motor that moves left and right on the first slide. A chute is provided on the operating platform, and the first slide is parallel to the chute. The lower end of the cigarette box conveyor is fixed to the first slider, and the upper end of the cigarette box conveyor passes through the chute to receive cigarette boxes pushed by the cigarette pusher. The cigarette box conveyor delivers the cigarette boxes to the operating platform directly opposite the second conveyor belt. A seal feeder is installed on a second bracket between the first and second conveyor belts. An angle control bracket is fixed on the second bracket directly below the seal feeder. The lower end of an angle electric suction claw is mounted on the angle control bracket via a rotating shaft. The angle electric suction claw is driven by a rotary motor and moves left and right on the seal feeder. The dispenser and the operating platform rotate intermittently. As the cigarette box held by the cigarette box conveyor moves along the first slide, the angled electric suction claw conveys the seal obtained from the seal dispenser to the cigarette box clamped on the cigarette box conveyor. A second slide is fixed on the operating platform outside the second conveyor belt. The second slide is parallel to the second conveyor belt. A second slider is mounted on the second slide and is driven by a cylinder, causing the second slider to move back and forth along the second slide. A push rod is mounted on the second slider, which pushes the cigarette box from the cigarette box conveyor into the second conveyor belt. The second conveyor belt sends the sealed cigarette box out for the automatic seal-sticking device for recycling unsealed cigarette packs.

[0006] The present invention provides an automatic label pasting device for recycling unsealed cigarette packs, wherein: the angled electric suction claw is F-shaped in the vertical state, and the cigarette box conveying frame is C-shaped with an opening to the left. When the angled electric suction claw rotates to the operating platform, the cigarette box conveying frame passes through the angled electric suction claw, and the label adsorbed on the angled electric suction claw is transferred and pasted on the cigarette box.

[0007] The present invention provides an automatic sealing device for recycling unsealed cigarette packs, wherein the distance between the upper and lower horizontal bars of the F-type angled electric suction claw is greater than the thickness of the cigarette pack conveyor.

[0008] The present invention provides an automatic sealing device for recycling unsealed cigarette packs, wherein: a crossbeam is installed at the other end of a first conveyor belt, and a first sensor is installed on the crossbeam for detecting cigarette packs.

[0009] The present invention discloses an automatic sealing device for recycling unsealed cigarette packs, wherein: the angle control frame is a quarter-circular arc plate, and a mounting hole is opened at the lower right end and the upper left end of the arc plate respectively. A second sensor is installed in the mounting hole, and the second sensor is used to detect the position of the angle electric suction claw.

[0010] The present invention provides an automatic sealing device for recycling unsealed cigarette packs, wherein: a cigarette guide bend is installed on a first conveyor belt frame at the other end of a first conveyor belt for guiding the cigarette packs onto an operating platform.

[0011] The present invention provides an automatic sealing device for recycling unsealed cigarette packs, wherein baffles are respectively installed on the operating platforms on both sides of the chute.

[0012] The present invention provides an automatic sealing device for recycling unsealed cigarette packs, wherein: it further includes a controller, which is connected to a first sensor, a second sensor, a motor driving a first conveyor belt, a motor driving a second conveyor belt, a cylinder, a rotary motor, a reciprocating motor, and a cigarette-pushing cylinder driving a cigarette-pushing plate.

[0013] Compared with existing manual packaging methods for recycled unsealed cigarette packs, this invention has the following advantages:

[0014] 1. The quality of the sealed cigarette packs is guaranteed after the seals are affixed, which helps to improve the homogeneity of cigarette products;

[0015] 2. The defect rate is reduced, saving raw materials;

[0016] 3. It reduced the labor intensity of workers;
