[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1 and 2As shown, a carton edge sealing device includes a frame 1, a support plate 2 and a roller conveyor 3 are respectively installed on both sides of the top of the frame 1, a first folding component 4 is fixedly connected to one end of the frame 1, a side plate 5 is symmetrically arranged on the top of the frame 1, a second folding component 6 is arranged at one end inside the side plate 5, a third folding component 7 is symmetrically arranged inside the side plate 5, and a limit strip 11 is symmetrically arranged on the top of the support plate 2.

[0020] According to the above structure, the carton to be edge-sealed is placed between two limit bars 11 during use. Under the action of the carton's own weight and the gravity of the items inside, the carton is stably placed on the support plate 2. One of the box covers of the carton is bent inward and pushed forward by the first folding component 4. When the carton passes through the second folding component 6, the second folding component 6 bends the other box cover of the carton. When the carton passes through two third folding components 7, the third folding components 7 bend the last two box covers. After being pushed by the first folding component 4, the four box covers of the carton can be bent, thereby improving the edge sealing efficiency.

[0021] like Figure 3 As shown, the first folding assembly 4 includes an L-shaped frame 41 fixedly connected to one end of the frame 1, a multi-stage electric telescopic rod 42 is fixedly connected inside the L-shaped frame 41, one end of the multi-stage electric telescopic rod 42 is fixedly connected to an L-shaped push plate 43, the top of the L-shaped push plate 43 is fixedly connected to a first vertical plate 44, and both sides of the L-shaped frame 41 are fixedly connected to reinforcing ribs 45.

[0022] According to the above structure, when sealing the edge, the L-shaped push plate 43 is driven to move by extending the multi-stage electric telescopic rod 42. The top of the L-shaped push plate 43 first pushes the box cover of the carton to bend. When the side of the L-shaped push plate 43 contacts the carton, the carton is pushed to the left. The setting of the first vertical plate 44 facilitates pushing the box cover of the bent carton.

[0023] like Figure 3 As shown, the second folding assembly 6 includes a top plate 61, the top of the top plate 61 is fixedly connected to a second vertical plate 62, the top of the second vertical plate 62 is symmetrically fixedly connected to a cross plate 63, and one end of the two cross plates 63 is fixedly connected to one side of the two side plates 5 respectively.

[0024] According to the above structure, when the carton is pushed to one end of the top plate 61, the other box cover of the carton is automatically bent under the obstruction of the top plate 61 and the second vertical plate 62.

[0025] like Figure 4 As shown, the third folding assembly 7 includes a pressure plate 71 and a guide plate 72, a connecting plate 73 is fixedly connected between the pressure plate 71 and the guide plate 72, one side of the guide plate 72 and the top of the pressure plate 71 are fixedly connected with equidistantly distributed connecting rods 74, and one end of the connecting rod 74 is fixedly connected to one side of the side plate 5.

[0026] According to the above structure, the carton continues to move to the left and moves between the two guide plates 72. The guide plates 72 squeeze the last two box covers inward. After being guided by the connecting plate 73, the pressing plate 71 finally presses the box covers down to bend the last two box covers of the carton downward. At this time, the first vertical plate 44 and the horizontal plate 63 are distributed in the gap between the two box covers, and the carton is transported forward under the drive of the roller conveyor 3.

[0027] The working principle of the utility model is as follows: when in use, the carton to be edge-sealed is placed between two limit bars 11, and under the action of the deadweight of the carton and the gravity of the articles inside, the carton is stably placed on the support plate 2, and one of the box covers of the carton is folded inward and pushed forward by the first folding assembly 4, and when the carton passes through the second folding assembly 6, the second folding assembly 6 folds the other box cover of the carton, and when the carton passes through the two third folding assemblies 7, the third folding assemblies 7 fold the last two box covers, and after being pushed by the first folding assembly 4, the four box covers of the carton can be folded, thereby improving the edge sealing efficiency. When edge sealing, the L-shaped push plate 43 is driven to move by extending the multi-stage electric telescopic rod 42. The top end of the L-shaped push plate 43 first pushes the box cover of the carton to bend. When the side of the L-shaped push plate 43 contacts the carton, the carton is pushed to the left. The setting of the first vertical plate 44 facilitates pushing and bending the box cover of the carton. When the carton is pushed to one end of the top plate 61, the other box cover of the carton is automatically bent under the obstruction of the top plate 61 and the second vertical plate 62, and the carton continues to move to the left and moves between the two guide plates 72. The guide plates 72 squeeze the last two box covers inwardly. After being guided by the connecting plate 73, the pressing plate 71 finally presses the box cover down to bend the last two box covers of the carton downward. At this time, the first vertical plate 44 and the horizontal plate 63 are distributed in the gap between the two box covers, and the carton is conveyed forward under the drive of the roller conveyor 3.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
