[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The terms "first" and "second" in the specification and claims of this utility model may explicitly or implicitly include one or more of the features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] The following is combined Figure 1 This invention describes a carton sealing device and a carton sealing production line equipment.

[0023] like Figure 1 As shown, in an embodiment of this utility model, the carton sealing device includes: a pair of first connecting plates 1, a sealing mechanism 2, and a cutting mechanism 3. The pair of first connecting plates 1 are arranged opposite to each other, and the sealing mechanism 2 and the cutting mechanism 3 are located between the pair of first connecting plates 1. The sealing mechanism 2 is rotatably connected to the pair of first connecting plates 1, and plastic tape is laid on the sealing mechanism 2. The cutting mechanism 3 includes a cutting blade 31. The sealing mechanism 2 has a switchable first state and a second state. When the carton is pressed onto the sealing mechanism 2, the sealing mechanism 2 is in the first state, and the sealing mechanism 2 is perpendicular to the first connecting plates 1, with the cutting blade 31 located below the sealing mechanism 2. When the carton is separated from the sealing mechanism 2, the sealing mechanism 2 is in the second state, and the sealing mechanism 2 is inclined to the first connecting plates 1, with the cutting blade 31 extending beyond the pair of first connecting plates 1.

[0024] Specifically, a pair of first connecting plates 1 are arranged opposite each other, forming a moving track for sealing the carton. A sealing mechanism 2 and a cutting mechanism 3 are located between the pair of first connecting plates 1, with the sealing mechanism 2 rotatably connected to the pair of first connecting plates 1. In the initial state, i.e., before the carton is conveyed onto the pair of first connecting plates 1, the sealing mechanism 2 is tilted relative to the first connecting plates 1; this is the second state of the sealing mechanism 2. The cutting blade 31 of the cutting mechanism 3 extends beyond the pair of first connecting plates 1.

[0025] When the carton is conveyed to the pair of first connecting plates 1, the carton comes into contact with the sealing mechanism 2. Under the pressure of the carton, the sealing mechanism 2 rotates relative to the first connecting plates 1 and eventually becomes perpendicular to them; this is the first state of the sealing mechanism 2. As the carton moves along the first connecting plates 1, it presses against the cutting mechanism 3, causing the cutting mechanism 3 to move downwards, positioning the cutting blade 31 below the sealing mechanism 2. At this time, the plastic tape is horizontally positioned, and as the carton passes the sealing mechanism 2, the plastic tape adheres to the sealed area of ​​the carton.

[0026] When the carton moves outside the sealing mechanism 2, the carton separates from the sealing mechanism 2, and both the sealing mechanism 2 and the cutting blade 31 return to their initial state. The cutting blade 31 extends beyond the pair of first connecting plates 1, cutting the plastic tape between the carton and the sealing mechanism 2. This operation allows for the automatic sealing of multiple cartons.

[0027] The carton sealing device provided in this embodiment of the utility model, by setting a sealing mechanism and a cutting mechanism, can seal the carton when it is pressed on the sealing mechanism; and cut the plastic tape when the carton leaves the sealing mechanism, thus realizing automatic sealing of the carton and automatic cutting of the plastic tape, eliminating the need for manual sealing, improving the efficiency of carton sealing, and reducing the labor intensity of operators.

[0028] like Figure 1 As shown in the embodiment of this utility model, the sealing mechanism 2 includes a first wheel assembly, which is disposed between a pair of first connecting plates 1 and rotatably connected to the first connecting plates 1. Plastic tape is disposed on the first wheel assembly. The first wheel assembly has a first state and a second state. When the carton is pressed onto the first wheel assembly, the first wheel assembly is in the first state. When the carton is separated from the first wheel assembly, the first wheel assembly is in the second state.

[0029] Specifically, when the carton is not in contact with the first wheel assembly, the first wheel assembly is in its second state, with the first wheel assembly tilted relative to the first connecting plate 1, and plastic tape wrapped around it with the adhesive side facing upwards. When the carton comes into contact with the first wheel assembly, the first wheel assembly rotates relative to the first connecting plate 1, eventually reaching a horizontal state. At this point, the plastic tape is also horizontal, and as the carton passes over the first wheel assembly, the plastic tape adheres to the seal of the carton.

[0030] like Figure 1 As shown, in an embodiment of this utility model, the first wheel assembly includes: a first transmission wheel 21, a first connecting member 22, and a second transmission wheel 23. The first connecting member 22 has a frame-shaped structure, and its two sides are respectively rotatably connected to a pair of first connecting plates 1. The first transmission wheel 21 and the second transmission wheel 23 are both disposed on the first connecting member 22, and are arranged in parallel. Plastic tape is wrapped around the first transmission wheel 21 and the second transmission wheel 23. When the first wheel assembly is in the second state, the second transmission wheel 23 is located above the first connecting plate 1, and the first transmission wheel 21 is located between the pair of first connecting plates 1. When the carton is conveyed to the pair of first connecting plates 1, the carton contacts the second transmission wheel 23, causing the first wheel assembly to rotate from an inclined state to a horizontal state. As the carton moves on the second transmission wheel 23 and the first transmission wheel 21, the plastic tape is adhered to the seal of the carton.

[0031] like Figure 1 As shown, in an embodiment of this utility model, the sealing mechanism 2 further includes a second wheel assembly and an elastic element 25. The second wheel assembly is rotatably connected to a pair of first connecting plates 1, and the second wheel assembly is symmetrically arranged with the first wheel assembly. The cutting blade 31 is located between the first wheel assembly and the second wheel assembly. The two ends of the elastic element 25 are respectively connected to the first wheel assembly and the second wheel assembly, so that the second wheel assembly has the same first state and second state as the first wheel assembly.

[0032] Specifically, in this embodiment, the structure of the second wheel group is the same as that of the first wheel group, and the second wheel group is connected to the first wheel group through an elastic element 25. The plastic tape is only wrapped around the first wheel group. When the carton presses against the first wheel group, the first wheel group rotates, causing the elastic element 25 to compress, thereby driving the second wheel group to move symmetrically with the first wheel group. That is, when the first wheel group is in the first state, the second wheel group is also in the first state, and the carton can move along the first wheel group and the second wheel group. When the carton leaves the second wheel group, the elastic element 25 extends, using elastic force to drive the first wheel group and the second wheel group to move away from each other, ultimately causing both the first wheel group and the second wheel group to be in the second state.

[0033] like Figure 1 As shown in the embodiment of this utility model, the sealing mechanism 2 further includes a pair of second connecting plates 24, which are disposed opposite to each other between a pair of first connecting plates 1, and the first connecting member 22 is rotatably connected to the pair of second connecting plates 24.

[0034] Furthermore, the sealing mechanism 2 also includes a pair of third connecting plates 26, which are disposed outside the pair of second connecting plates 24 and located between the pair of first connecting plates 1. The second connecting plates 24 are connected to the third connecting plates 26, and the third connecting plates 26 are connected to the first connecting plates 1.

[0035] like Figure 1 As shown in the embodiment of this utility model, the cutting mechanism 3 includes a pair of second connecting members 32, which are arranged opposite to each other. The first end of each second connecting member 32 is dampedly connected to the third connecting plate 26, and the second end of each second connecting member 32 is connected to the cutting blade 31. The second connecting member 32 has a switchable first position and a second position. When the carton is pressed against the second connecting member 32, the second connecting member 32 is arranged parallel to the first connecting plate 1. When the carton is separated from the second connecting member 32, the second connecting member 32 is arranged at an angle to the first connecting plate 1.

[0036] Specifically, in the initial state, the second connector 32 and the third connecting plate 26 are angled together, which is the second position of the second connector 32, and the cutting blade 31 is located above the first connecting plate 1. When the carton moves onto the first connecting plate 1, the carton presses against the second connector 32, causing the second end of the second connector 32 to move downwards, eventually bringing the second connector 32 to a horizontal position, which is the first position of the second connector 32. At this time, the cutting blade 31 is located below the first wheel assembly, allowing the plastic tape to be adhered to the seal of the carton. When the carton moves away from the second connector 32, the second connector 32 returns to its initial state under the action of damping force, and the cutting blade 31 extends beyond the pair of first connecting plates 1 to cut the plastic tape.

[0037] like Figure 1As shown, the cutting mechanism 3 also includes a pair of driving members 33, which are arranged opposite to each other. The first end of each driving member 33 is connected to a second connecting member 32, and the second end of each driving member 33 is a free end. In the initial state, the driving members 33 are inclined to the first connecting plate 1, and the free ends of the driving members 33 extend beyond the pair of first connecting plates 1. When the carton is pressed onto the driving members 33, the driving members 33 move downward, causing the second connecting member 32 to move downward. The driving members 33 eventually reach a horizontal state, and the cutting blade 31 is located below the first wheel assembly. After the carton moves away from the driving members 33, the driving members 33 return to the initial state, thereby causing the second connecting member 32 and the cutting blade 31 to return to the initial state.

[0038] like Figure 1 As shown, the cutting blade 31 has multiple teeth facing the surface of the plastic tape to cut the plastic tape.

[0039] Furthermore, in an embodiment of this utility model, the carton sealing device further includes a third connector, which is connected to any of the first connecting plates 1. The third connector is used to fix the plastic tape, and the starting end of the plastic tape is wrapped around the first transmission wheel 21 and the second transmission wheel 23.

[0040] This utility model embodiment also provides a carton sealing production line equipment, including a conveying mechanism and a carton sealing device. The conveying mechanism is located at the front end of the carton sealing device and is used to convey the carton to the carton sealing device. The carton sealing device is used to seal the opening of the carton and cut the plastic tape.

[0041] In this embodiment, the conveying mechanism can be a conveyor belt or other forms of conveying structure with conveying function in the prior art.

[0042] The carton sealing production line equipment provided in this embodiment of the utility model realizes automatic carton conveying, automatic sealing and automatic cutting of plastic tape by setting up a conveying mechanism and a carton sealing device, thereby improving the production efficiency of carton sealing.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
