[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] like Figures 1-7 As shown, this embodiment provides a carton side sealing mechanism 1, including an adhesive dispensing assembly 11, an adhesive sticker assembly 12, a carton flipping assembly 13, a carton baffle assembly 14, a carton positioning assembly 15, an ear folding assembly 16, and a packaging base plate 17. The adhesive dispensing assembly 11 is used to apply adhesive to both sides of the back M2 of the carton on the side sealing plate F. The adhesive sticker assembly 12 is used to flip the side sealing plate F close to the carton X1, and press the adhesive surface against the ear M5 for adhesion. The carton flipping assembly 13 is used to drive the carton X1 to flip so that its side opening faces the rear and upward. The carton baffle assembly 14 is used to provide front support for the carton X1 on the carton flipping assembly 13. The carton positioning assembly 15 is used to perform adsorption and positioning on both sides of the carton X1 on the carton flipping assembly 13. The ear folding assembly 16 is used to fold the ear M5 on the carton X1 inward.

[0030] It should be noted that, in this embodiment, the cardboard box X1 is a semi-finished cardboard box folded by a folding mechanism, having a top opening and a side opening. Specifically, the front M1 of the cardboard box faces forward, the left side M3 and the right side M4 face backward, the lower edges of the left side M3 and the right side M4 are folded up relative to each other, and the lower edge of the front M1 is folded up backward and upward to cover the bottom surface of the lower edges of the left side M3 and the right side M4; the rear ends of the left side M3 and the right side M4 both have outwardly extending lugs M5. In this embodiment, the side sealing plate F is a cardboard piece with the rear M2 of the cardboard box and its attached upper and lower folds, which is to be glued to the cardboard box X1.

[0031] The dispensing assembly 11 comprises front and rear dispensing driving members 111, a dispensing moving table 112 fixedly connected with the movable ends of the front and rear dispensing driving members 111, dispensing side shifting driving members 113 arranged on the left and right sides of the dispensing moving table 112, and two dispensing side shifting driving members 113 facing each other. A dispensing bracket 114 is mounted on the movable end of the dispensing side shifting driving member 113, a dispensing gun 115, specifically a strip-shaped hot melt glue gun, is arranged on the dispensing bracket 114, and a side sealing push block 116 is further mounted on the dispensing bracket 114 and located on the inner side of the dispensing gun 115, and the dispensing gun 115 is located above the side sealing push block 116. The dispensing gun 115 and the side sealing push block 116 will be pushed and shifted by the dispensing side shifting driving member 113 and moved forward and backward by the front and rear dispensing driving members 111. The side sealing push blocks 116 and the dispensing guns 115 on the left and right sides of the dispensing moving table 112 will move towards each other or away from each other.

[0032] When the dispensing assembly 11 is in action, the side sealing push block 116 is first moved to the outside of the rear side M2 of the carton of the side sealing plate F, and then the side sealing push blocks 116 on the left and right sides move towards each other to align the side sealing plate F to the fixed position. At this time, the dispensing guns 115 on the left and right sides are located above the front end of the inner edge of the left and right sides of the rear side M2 of the carton, respectively, and the dispensing gun 115 moves backward with the dispensing moving table 112 while dispensing glue and coating on the inner edge of the side of the rear side M4 of the carton.

[0033] When the side sealing plate F is placed, the dispensing gun 115 and the side sealing push block 116 are moved to the left and right sides to leave the space for placing the plate.

[0034] The sticker assembly 12 comprises two spaced-apart sticker uprights 121 which are erected on the bag loading base plate 17. The sticker uprights 121 are fixed with an axle connecting base plate 122. The axle connecting base plate 122 is provided with sticker bearing seats 123 on both sides. The sticker bearing seats 123 are provided with sticker bearing members. The sticker bearing members on both sides are connected with a synchronously rotatable sticker pressing plate 124. The outer side of one sticker bearing member is further connected with a sticker turnover driving member 125. The front side of the sticker pressing plate 124 is further provided with a transition plate 126 which is horizontally fixed on the axle connecting base plate 122 through a transition support plate 1261. The sticker pressing plate 124 is provided with a paper pushing assembly 127 on both sides. The paper pushing assembly 127 comprises a paper pushing block 1271 and a paper pushing driving member 1272 which drives the paper pushing block 1271 to push forward. The pushing path of the paper pushing block 1271 is perpendicular to the sticker pressing plate 124. The sticker pressing plate 124 is correspondingly provided with a paper pushing hole through which the paper pushing block 1271 pushes. The sticker pressing plate 124 is further provided with a paper suction hole 1241 in the middle. The paper suction hole 1241 is provided below with a sticker suction assembly 128. The sticker suction assembly 128 comprises a sticker suction disc block 1281 and a sticker suction disc 1282. The sticker suction disc 1282 is fixed on the sticker suction disc block 1281. The sticker suction disc 1282 is arranged perpendicularly to the sticker pressing plate 124. The suction disc surface of the sticker suction disc 1282 is in the same plane as the upper surface of the sticker pressing plate 124. The sticker suction assembly 128 further comprises a sticker suction disc driving member 1283. The fixed end of the sticker suction disc driving member 1283 is mounted on the bottom surface of the sticker pressing plate 124. The movable end is fixedly connected with the sticker suction disc block 1281.

[0035] The sticker pressing plate 124 can be used to receive the side sealing plate F to be glued. The side sealing plate F can be turned over with the sticker pressing plate 124 to be close to the carton X1. The transition plate 126 can be used to rest the flange of the carton rear M4 below the back M4 of the side sealing plate F. The paper pushing assembly 127 can push the carton rear M4 on both sides away from the sticker pressing plate 124 and press the carton rear M4 on both sides to the ear edges M5 of the carton X1, so that the carton rear M4 on both sides is adhered to the ear edges M5, and the side sealing action of the carton X1 is completed. The sticker suction assembly 128 can suck the carton rear M4 on the sticker pressing plate 124, so as to avoid the side sealing plate F from sliding off the sticker pressing plate 124 when the sticker pressing plate 124 is turned over. In order to avoid the front end of the side sealing plate F from being hung on the carton turnover mechanism 13 when the side sealing plate F is placed, the placement position of the side sealing plate F will be slightly later. The sticker suction disc driving member 1283 drives the sticker suction disc 1282 to move forward and backward for a short distance, and then drives the side sealing plate F to move forward until the designated position. During the sticker action, the already folded ear edges M5 have a tendency to turn back. The paper pushing block 1271 has a tendency to press the left and right sides of the carton rear M2 forward. Under the relative action of the two forces, the left and right sides of the carton rear M2 have a better adhesion effect with the ear edges M5.

[0036] Before pasting the paper, the box overturning plate 131 is first rotated to be vertical, and the bottom of the paper box X1 will press the folded edge of the back M2 of the paper box on the transition plate 126, and then the paper pasting plate 124 drives the back M2 of the paper box to overturn upward, and the back M2 of the paper box and the folded edge below it will have a certain folding effect with the overturning of the paper pasting plate 124. When the paper pasting plate 124 finally reaches the paper pasting position, the back M2 of the paper box and the folded edge below it can produce a right angle effect, and the folded edge below the back M2 of the paper box is automatically folded on the bottom of the paper box X1. Therefore, there is no need for additional action to fold the folded edge below the back M2 of the paper box, and the structure design is simple and ingenious.

[0037] The paper box overturning assembly 13 comprises a box overturning plate 131, a box overturning bearing seat 132, a box overturning rotating shaft 133, a box overturning fixed seat 134, and a box overturning driving member 135. The box overturning plate 131 is in the shape of a long plate, and has a groove on the back side for accommodating the transition plate 126. Preferably, the transition plate 126 is slightly higher than the box overturning plate 131 in the horizontal state, so that the folded edge below the back M2 of the paper box will not be jammed by the edge of the box overturning plate 131. The box overturning bearing seat 132 is fixed to the bottom of the box overturning plate 131, and there are two box overturning bearing seats 132 arranged apart from each other. The box overturning rotating shaft 133 is arranged in the middle of the box overturning bearing seat 132, and the box overturning plate 131 can be overturned along the box overturning rotating shaft 133. The two ends of the box overturning rotating shaft 133 are fixed to the box overturning fixed seat 134, and the box overturning fixed seat 134 is fixed to the packing bottom plate 17. The fixed end of the box overturning driving member 135 is hinged to the packing bottom plate 17, and the movable end of the box overturning driving member 135 is hinged to the box overturning plate 131 through the hinge seat 136, and the hinge seat 136 is fixed to the middle of the back end of the bottom surface of the box overturning plate 131. The box overturning driving member 135 is in an inclined state as a whole.

[0038] The blocking box assembly 14 comprises an L-shaped blocking plate 141, a blocking box driving member 142 and a blocking box fixing plate 143. The vertical plate of the L-shaped blocking plate 141 is perpendicular to the box turnover plate 131 and close to the front end of the box turnover plate 131. The vertical plate of the L-shaped blocking plate 141 can move up and down on the front end of the box turnover plate 131. The front end of the flat plate of the L-shaped blocking plate 141 is fixed with the movable end of the blocking box driving member 142. The blocking box driving member 142 is arranged vertically to the box turnover plate 131. The fixed end of the blocking box driving member 142 is fixedly connected with the blocking box fixing plate 143. The blocking box fixing plate 143 is fixed on the bottom surface of the rear side of the box turnover plate 131. When the movable end of the blocking box driving member 142 is driven to pull up, the L-shaped blocking plate 141 will rise, providing front side support for the paper box X1 placed on the box turnover plate 131. At the same time, since the blocking box assembly 14 is installed on the box turnover plate 131, it will be turned synchronously with the box turnover plate 131. The vertical plate of the L-shaped blocking plate 141 is always perpendicular to the box turnover plate 131, ensuring the coordination of the turnover box and the blocking box.

[0039] The box positioning assembly 15 has two groups and is symmetrically arranged on the left and right sides of the upper surface of the box turnover plate 131. The box positioning assembly 15 comprises a positioning fixing support plate 151 fixed on one side of the upper surface of the box turnover plate 131. The box positioning driving member 152 is installed on the positioning fixing support plate 151. The movable end of the box positioning driving member 152 is fixed with the box positioning plate 153. The outer end of the box positioning plate 153 is installed with the box positioning suction cup 154. The left and right box positioning suction cups 154 are oppositely arranged. The box positioning driving member 152 can drive the box positioning suction cup 154 to move in the left and right directions. The box positioning suction cups 154 of the two groups of box positioning assemblies 15 move towards each other, which can respectively adsorb and position the left side M3 and the right side M4 of the paper box X1 on the box turnover plate 131, avoiding the influence of the inner folding on the placement of the bag, and also playing a certain positioning role on the whole paper box X1. In combination with the blocking box assembly 14, the paper box X1 in the inclined state is prevented from sliding down. At the same time, since the box positioning assembly 15 is installed on the box turnover plate 131, it will be turned synchronously with the box turnover plate 131, ensuring the coordination of the turnover box and the box positioning.

[0040] The two box positioning assemblies 15 are each installed with an ear folding assembly 16.

[0041] The ear folding assembly 16 comprises an ear folding rear pushing driving member 161, an ear folding side pushing connecting plate 162, an ear folding side pushing driving member 163 and an ear folding pushing plate 164. The fixed end of the ear folding rear pushing driving member 161 is fixed on the positioning fixed support plate 151 and located outside the box body positioning driving member 152. The movable end of the ear folding rear pushing driving member 161 is fixedly connected with the ear folding side pushing connecting plate 162. The ear folding side pushing connecting plate 162 is provided with a fixing member of the ear folding side pushing driving member 163. The movable end of the ear folding side pushing driving member 163 is provided with the ear folding pushing plate 164. The ear folding pushing plate 164 is a vertical long thin plate. The height of the ear folding pushing plate 164 corresponds to the ear edge M5. The left and right ear folding pushing plates 164 are oppositely arranged. The ear folding pushing plate 164 is driven by the ear folding rear pushing driving member 161 to move forward and backward and is driven by the ear folding side pushing driving member 163 to move left and right. After the carton X1 is loaded with the bag, the ear folding pushing plate 164 moves backward and sideward to fold and press the ear edge M5. The ear folding pushing plate 164 moves to the outside of the ear edge M5 first and then moves to press the ear edge M5 sideward. Finally, the ear edge M5 is close to being perpendicular to the left face M3 of the carton or the right face M4 of the carton. At the same time, since the ear folding assembly 16 is installed on the positioning fixed support plate 151, it will be synchronized with the box body turning plate 131 to turn over, thereby ensuring the turning over of the box body, the positioning of the suction box and the cooperation of the ear folding.

[0042] When the box body turning plate 131 rotates, the ear folding assembly 16 can always press on the ear edge M5 to serve as a rear stop for the goods in the carton X1 during the rotation of the carton X1. After the carton X1 is turned over, the ear folding assembly 16 leaves a space for the ear edge M5 to stop the goods and then performs a side sealing plate sticking action.

[0043] After the carton X1 is loaded with the goods and the side plate is adhered and the bottom face is folded, the carton shape with the right face M4 of the carton folded downward is a carton two. During the dragging of the carton two, the box body turning plate 131 simultaneously provides support for the folded edge of the rear face M2 of the carton and the folded edge of the front face M1 of the carton to ensure that the bottom part of the carton two does not scatter the goods. The carton two will be removed later and the bottom will be sealed with adhesive tape.

[0044] The specific working process of the carton side sealing in the embodiment is as follows: 1.
