Description
Technical Field
[0001] The utility model relates to the technical field of upper sealing machines, and more specifically, to an upper sealing machine with firm sealing. Background Art
[0002] The upper sealing machine, namely the carton sealing machine, is mainly applicable to the carton sealing and packaging. It can operate independently or be used in conjunction with an assembly line. It can operate on a single carton or be used in combination with equipment such as a carton forming and opening machine, a cartoning machine, a labeling machine, a strapping machine, a pallet stacking machine, and a conveyor to form a packaging assembly line, and it is an essential equipment for packaging assembly line operations.
[0003] In order to ensure the firm sealing of the top of the carton, the existing upper sealing machines usually set secondary pressing wheels on the equipment to re-press the sealing tape, so as to ensure the firm sealing of the tape to the top of the carton. Although this method improves the firmness of the tape's sealing to the top of the carton, if there is dust on the top of the carton, after the tape adheres to the top of the carton, it will greatly affect the firmness of the tape's adhesion to the top of the carton, and the tape is very likely to separate from the carton. Even if it is repeatedly rolled and reinforced, the effect is minimal. In view of this, we propose an upper sealing machine with firm sealing. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide an upper sealing machine with firm sealing, so as to solve the technical problem that when the existing upper sealing machine seals the top of the carton, the sealing tape is easily affected by dust, resulting in poor adhesion of the tape to the top of the carton.
[0005] To solve the above technical problems, the utility model provides the following technical solution: an upper sealing machine with firm sealing, including an upper sealing machine main body, a pretreatment structure is arranged at the front end of the top of the conveying table of the upper sealing machine main body, the pretreatment structure includes a concave frame, the concave frame is arranged on the conveying table of the upper sealing machine main body, a hydraulic cylinder is arranged at the center of the inner top of the concave frame, a blowing plate is arranged at the piston end of the hydraulic cylinder, and a blowing structure is arranged on the top of the concave frame;
[0006] The blowing plate is in a triangular strip shape, and blowing ports are arranged on the inclined surfaces on both sides of the blowing plate, and the blowing ports are arranged obliquely.
[0007] Through the designed pretreatment structure of the utility model, before the carton enters the main body of the upper sealer for sealing, the carton will pass through the pretreatment structure in advance. During the process of the carton passing through the pretreatment structure, the hydraulic cylinder in the pretreatment structure is controlled to drive the blowing plate to lift and lower, so that the blowing plate approaches the top of the carton. Then, the air blowing structure is controlled to supply air to the blowing plate, and then the blowing plate blows air towards the top of the carton, so that the dust on the top of the carton can be directly blown away, ensuring the cleanliness of the top of the carton. In order to facilitate the subsequent adhesion of the tape to the top of the carton, the tape can be firmly adhered to the top of the carton, thus ensuring the firmness of the tape's sealing of the top of the carton. When the blowing plate blows air to clean the dust on the carton, the air flow blown out by the blowing plate is in the form of tilting forward and tilting backward. Therefore, during the process of the carton passing through the concave frame, it can not only blow and clean the dust on the top of the carton, but also clean the front and back sides of the carton, ensuring the firmness of the two ends of the tape adhered to the front and back sides of the carton, further improving the adhesion effect between the tape and the carton. Moreover, the air blowing ports arranged in the front and back of the blowing plate can achieve the effect of blowing and cleaning the top of the carton twice, improving the dust cleaning performance of the carton. When the air blowing structure supplies air to the blowing plate, the fan works, and then the air at the carton is absorbed through the air suction hood, so that the dust blown up on the carton together with the air can be inhaled and conveyed to the water tank. Then, the water source inside the water tank realizes the cleaning of the dust in the air, ensuring the cleanliness of the air. Then, the clean air is conveyed from the water tank to the blowing plate to complete the air supply operation. This method can effectively collect and process the dust blown off from the box body, avoid the dispersion of dust in the working environment, and ensure the cleanliness of the working environment.
[0008] Preferably, sliding grooves are formed on both sides inside the concave frame, sliders are slidably arranged inside the sliding grooves, and connecting rods are connected between the sliders and the blowing plate.
[0009] Preferably, the air blowing structure includes an air suction hood, a water tank and a fan. The air suction hood is arranged on both sides of the concave frame, the water tank is arranged in the center of the top of the concave frame, and the fan is arranged on one side of the top of the concave frame.
[0010] Preferably, an L-shaped installation pipe is arranged on one side of the top of the water tank, and the bottom end of the L-shaped installation pipe is located at the inner bottom of the water tank. The top end port of the L-shaped installation pipe is connected to the output end of the fan. A connection port is arranged on the other side of the top of the water tank. The connection port is connected to the input end of the blowing plate through a three-way hose. The output end of the fan is connected to the two air suction hoods through a conduit.
[0011] Preferably, the inside of the blowing plate and the air suction hood is hollow. The air suction hood is concave, and two groups of symmetric air suction ports are formed on the side of the air suction hood facing the blowing plate.
[0012] Preferably, a top port is arranged in the center of the top of the water tank, and a top cover is arranged on the top of the top port. A rubber plug is arranged at the bottom of the front side of the water tank.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. Through the designed pretreatment structure of the present utility model, before the carton enters the main body of the upper sealer for sealing, the carton will pass through the pretreatment structure in advance. During the process of the carton passing through the pretreatment structure, the hydraulic cylinder in the pretreatment structure is controlled to drive the air blowing plate to lift and lower, so that the air blowing plate approaches the top of the carton. Then, the air blowing structure is controlled to send air to the air blowing plate, and then the air blowing plate will blow air to the top of the carton, so as to directly blow off the dust on the top of the carton, ensure the cleanliness of the top of the carton, so that when the tape seals the top of the carton subsequently, the tape can be firmly adhered to the top of the carton, thereby ensuring the firmness of the tape sealing the top of the carton, and solving the technical problem that when the current upper sealer seals the top of the carton, the sealing tape is easily affected by dust, resulting in the tape not being firmly adhered to the top of the carton. Therefore, the present utility model has the advantage of more firmly packaging the top of the carton.
[0015] 2. The overall shape of the air blowing plate of the present utility model is triangular strip-shaped, and the air outlets on both sides of the air blowing plate are inclined. Therefore, when the air blowing plate blows air to clean the dust on the carton, the air flow blown out by the air blowing plate is in the form of being inclined forward and inclined backward. Therefore, during the process of the carton passing through the concave-shaped frame, it can not only blow air to clean the dust on the top of the carton, but also clean the front and back sides of the carton, which can ensure the firm adhesion of both ends of the tape to the front and back sides of the carton, further improve the adhesion effect between the tape and the carton, and the air outlets arranged in the front and back of the air blowing plate can achieve the effect of blowing air twice to clean the top of the carton, improving the dust cleaning performance of the carton.
[0016] 3. The air blowing structure in the present utility model is composed of an air suction hood, a water tank and a fan. Therefore, when the air blowing structure sends air to the air blowing plate, the fan works, and then the air at the carton is absorbed through the air suction hood, so that the dust blown up on the carton together with the air can be inhaled and conveyed to the water tank. Then, the water source inside the water tank realizes the cleaning of the dust in the air, ensuring the cleanliness of the air. Then, the clean air is conveyed from the water tank to the air blowing plate to complete the air supply operation. This way can effectively collect and process the dust blown off from the box body, avoid the dust from escaping in the working environment, and ensure the cleanliness of the working environment.

During the process of the carton passing through the concave frame 3 of the pretreatment structure 2, control the hydraulic cylinder 4 in the pretreatment structure 2 to drive the blowing plate 5 to lift and lower, so that the blowing plate 5 approaches the top of the carton, and then control the blowing structure 6 to send air to the blowing plate 5, and then the blowing plate 5 will blow air to the top of the carton, so as to directly blow away the dust on the top of the carton, ensure the cleanliness of the top of the carton, so that when the tape in the subsequent upper sealing machine main body 1 seals the top of the carton, the tape can be firmly adhered to the top of the carton, thus ensuring the firmness of the tape sealing the top of the carton.
[0026] Specifically, slide grooves 301 are opened on both sides inside the concave frame 3, and slide blocks 302 are slidably arranged inside the slide grooves 301. A connecting rod 502 is connected between the slide blocks 302 and the blowing plate 5. With the cooperation of the slide grooves 301, the slide blocks 302 and the connecting rod 502, the blowing plate 5 is stably supported to ensure the stability of the blowing plate 5.
[0027] In an embodiment of the present utility model, the blowing plate 5 is in a triangular strip shape. Blowing ports 501 are provided on the inclined surfaces on both sides of the blowing plate 5, and the blowing ports 501 are arranged obliquely. When the blowing plate 5 blows air to clean the dust on the cardboard box, the air flow blown out by the blowing plate 5 is in the form of being obliquely forward and obliquely backward.

[0031] Working principle: This embodiment provides an upper sealer with firm sealing. First, before the carton enters the main body 1 of the upper sealer for sealing its top, the carton will pass through the pretreatment structure 2 in advance. During the process of the carton passing through the concave frame 3 of the pretreatment structure 2, control the hydraulic cylinder 4 in the pretreatment structure 2 to drive the blowing plate 5 to lift and lower, so that the blowing plate 5 approaches the top of the carton. Then control the air blowing structure 6 to send air to the blowing plate 5, and then the blowing plate 5 will blow air to the top of the carton, so as to directly blow away the dust on the top of the carton, ensure the cleanliness of the top of the carton, and facilitate the subsequent packaging of the top of the carton by the tape in the main body 1 of the upper sealer, so that the tape can be firmly adhered to the top of the carton, thus ensuring the firmness of the tape's sealing of the top of the carton;
[0032] Secondly, when the blowing plate 5 blows air to clean the dust of the carton, the air flow blown out by the blowing plate 5 is in the form of tilting forward and tilting backward.

[0033] Finally, when the air blowing structure 6 sends air to the blowing plate 5, the fan 9 works, and then absorbs the air at the carton through the air suction hood 7, so as to suck the dust blown up on the carton together with the air, and convey it to the water source inside the water tank 8 through the L-shaped installation pipe 801. Then the water source inside the water tank 8 cleans the dust in the air to ensure the cleanliness of the air. Then the clean air is output from the connection port 802 of the water tank 8 and then conveyed to the blowing plate 5 through the pipeline to complete the air supply operation. This method can effectively collect and process the dust blown off the box body, avoid the dust from escaping in the working environment, and ensure the cleanliness of the working environment.
