[0029] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0030] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present application.

[0031] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The accompanying drawings are the best embodiments of the automatic box sealing device for packaging boxes. The present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] An automatic box sealing device, comprising Figure 1 as well as Figure 2 As shown, it includes a pressing plate 2, which is used to press down the two pieces of cardboard at the sealing of the packaging box to make them in a horizontal state, which is convenient for pasting tape later. In order to guide the cardboard at the sealing, the front end of the pressing plate 2 is provided with a second guide plate 201 arranged obliquely upward.

[0034] The rear end of the pressing plate 2 is connected to a tape sleeve rod 5, a tape suction device is provided below the tape sleeve rod 5, and a blade 10 that moves up and down is provided at the rear end of the tape suction device. A telescopic device 11 is connected above the blade 10, and the telescopic device 11 is pneumatic or electric, both of which are prior art.

[0035] Depend on Figure 6 As shown, the tape adsorption device includes an adsorption tank 8 and a three-way valve 9. The bottom surface of the adsorption tank 8 is provided with a plurality of through holes 801. One interface of the three-way valve 9 is connected to the inner cavity of the adsorption tank 8 through a pipeline.

[0036] The three interfaces of the three-way valve 9 are respectively connected to the negative pressure pipeline, the air supply pipeline and the adsorption tank 8 through pipelines. The negative pressure pipeline and the air supply pipeline are both internal pipelines of the factory area, or connected to a vacuum pump and an air compressor.

[0037] The front end of the adhesive tape adsorption device is provided with a guide roller 7, and the guide roller 7 is connected to the adhesive tape sleeve connecting rod 5 through a bracket 4. In this embodiment, the front end of the adhesive tape adsorption device is provided with two guide rollers 7 arranged at intervals in an upper and lower manner.

[0038] Depend on Figure 7 As shown, the tape roll 12 is sleeved on the tape sleeve rod 5, and then the tape 1201 is led out, and its non-adhesive side abuts against the circumferential surface of the guide roller 7, and is guided by the guide roller 7 and passed to the bottom of the adsorption groove 8.

[0039] Before the pasting process begins, the adsorption groove 8 is connected to the negative pressure pipeline, and the tape 1201 is adsorbed by the negative pressure. When the packaging box starts to be sealed, the adsorption groove 8 is connected to the air supply pipeline, and the gas sprayed outward through the through hole 801 makes the tape 1201 tightly connected to the packaging box.

[0040] After completing the sealing of a packaging box, the blade 10 moves downward to cut the adhesive tape.

[0041] A vertically arranged side limit plate 1 is provided on both sides below the pressing plate 2. The side limit plate 1 is fixedly connected to the pressing plate 2 through the frame 3, and the bracket 4 is fixedly connected to the frame 3. A first guide plate 101 arranged outwardly tilted is provided at the front end of the side limit plate 1. A photoelectric beam sensor is provided on the frame 3 or the side limit plate 1 to detect the position of the packaging box.

[0042] In order to prevent the adhesive tape roll 12 from sliding off the adhesive tape sleeve connecting rod 5, the front end of the adhesive tape sleeve connecting rod 5 is provided with an adhesive tape anti-slip cover 6. The adhesive tape anti-slip cover 6 is detachably connected to the adhesive tape sleeve connecting rod 5.

[0043] Further, by Figures 3 to 5As shown, the end of the tape sleeve connecting rod 5 is coaxially provided with a plug hole 501, and a plurality of key slots 502 are concavely provided on the circumferential surface of the plug hole 501 close to the outside, and an annular rotating hole 503 is concavely provided on the inner circumferential surface of the plug hole 501. The tape anti-detachment cover 6 is coaxially fixed with an insertion shaft 601, and a locking key 602 is convexly provided on the circumferential surface of the end of the insertion shaft 601, and the height of the locking key 602 is the same as the depth of the rotating hole 503. After the locking key 602 passes through the key slot 502, it enters the inside of the rotating hole 503, and then rotates so that it is staggered with the key slot 502, so as to realize the fixed connection between the tape anti-detachment cover 6 and the tape sleeve connecting rod 5.

[0044] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
