[0037] refer to Figures 1 to 3 , the embodiment of the present application provides a paper box end surface forming device 100. The paper box end surface forming device 100 includes: a loading mechanism 110, a folding mechanism 120 and an ear insertion mechanism 130. Among them, the loading mechanism 110 has a cavity 101 and has an opening facing the first direction X. The main body of the paper box 200 is accommodated in the cavity 101. The end surface to be formed of the paper box 200 is unfolded outward from the opening along the first direction X. The folding mechanism 120 is arranged on one side of the opening of the loading mechanism 110 along the first direction X. The folding mechanism 120 is used to fold the first side and the second side of the paper box 200 that are relatively arranged along the second direction Y and the third side and the fourth side 204 that are relatively arranged along the third direction Z into shape. The ear insertion mechanism 130 is arranged on one side of the opening of the loading mechanism 110 along the first direction X. The ear insertion mechanism 130 is used to insert the paper ear 205 on the fourth side 204 of the paper box 200 into the ear slit on the third side. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. In order to better illustrate the embodiment of the present application, a rectangular coordinate system is established with the first direction X as the X-axis, the second direction Y as the Y-axis, and the third direction Z as the Z-axis. The first direction X is the direction of the long side of the paper box 200, the second direction Y is the direction of the wide side of the paper box 200, and the third direction Z is the direction of the height of the paper box 200.

[0038] The paper box end face forming device 100 provided in the embodiment of the present application, the folding mechanism 120 folds two groups of four side faces of the paper box 200 into shape, and inserts the paper ears 205 into the corresponding ear gaps through the ear insertion mechanism 130, thereby realizing the automatic forming of the end face of the paper box 200 with the paper ears 205, realizing the automation of the end face forming of the paper box 200, simplifying the production process, reducing dependence on manual labor, reducing labor costs, avoiding fatigue and errors in manual operation, improving the stability of the production process, greatly increasing the production speed, and being suitable for large-scale production needs; at the same time, the machine operation is precise, and each box folding can achieve the same quality and standard, ensuring the uniformity and standardization of the finished product.

[0039] Furthermore, the loading mechanism 110, the folding mechanism 120 and the ear inserting mechanism 130 are all fixed on the base plate. In this way, the position structure of the loading mechanism 110, the folding mechanism 120 and the ear inserting mechanism 130 is fixed to form a whole, which is convenient for positioning and ensures the uniformity and stability of the end surface molding of the paper box 200.

[0040] In one possible implementation, Figures 1 to 3 As shown, the folding mechanism 120 includes a first folding assembly 121. The first folding assembly 121 is arranged on a side of the first side away from the second side. The first folding assembly 121 includes a first push plate 1211 and a first driving member 1212. The first push plate 1211 is connected to the first driving member 1212. The first driving member 1212 drives the first push plate 1211 to push the first side to fold along the second direction Y toward the direction close to the second side. The first side is folded and formed by the first folding assembly 121, which has a simple structure and is easy to maintain. As an example, the first driving member 1212 can be a linear driving device that outputs a driving force along the second direction Y, for example, a servo electric cylinder with a push rod, which can push a short distance and a small force. For example, the first driving member 1212 can also be a linear drive, which can be electric (such as an electric linear slide, a servo motor with a linear guide), pneumatic or hydraulic drive, and is suitable for horizontal push applications that require precise control. For another example, the first driving member 1212 can also be a lifting device that outputs along the second direction Y. As an example, the first driving member 1212 can still be a linear driving device as described above, but the direction of the output driving force has a certain angle with the second direction Y. For example, the first driving member 1212 can output the driving force from the outside of the first side surface in a direction that is 45° to the first direction X, or the first side surface can be folded inwardly. In short, as long as the second side surface can be pushed inwardly from the outside of the second side surface, it will be fine.

[0041] In one possible implementation, Figures 1 to 3As shown, the first driving member 1212 is a rotary motor. The first push plate 1211 is fixed at the output end of the rotary motor, and the rotary motor drives the first push plate 1211 to push the first side to fold and form in the direction close to the second side. Selecting a rotary motor as the first driving member 1212 can make the first push plate 1211 not a fixed force point when applying a driving force to the first side, but gradually move downward along the third direction Z from the initial force point as the first driving member 1212 drives the first push plate 1211 to rotate, so that the area receiving the driving force from the first side is larger and the force is more uniform, avoiding the deformation of the first side of the paper box 200 caused by a single point of force, and reducing the occurrence of defective products.

[0042] Furthermore, the first push plate 1211 has a bending structure. Specifically, the first push plate 1211 has a connecting portion and an abutting portion that are interconnected. Among them, the connecting portion is used to be fixedly connected to the output end of the first driving member 1212, and the abutting portion is used to abut the first side surface. The bending structure refers to that the abutting portion and the connecting portion are not connected in a straight line, but have a certain angle or arc. The angle or arc is an angle or arc deflected in the direction in which the first side surface needs to be folded and formed. In this way, when the rotating motor drives the first push block to rotate and move toward the first side surface, the abutting portion gradually approaches the first side surface, and the contact range with the first side surface increases, such as 1 to Figure 3 As shown, when the abutting portion is perpendicular to the connecting portion, when the rotating motor drives the first push block to rotate until the connecting portion is parallel to the second direction Y, the abutting portion is parallel to the third direction Z, and the side walls of the abutting portion along the third direction Z all contact the first side surface, and the abutting area is large, so the first side surface can be better folded into shape.

[0043] In one possible implementation, Figures 1 to 3As shown, the folding mechanism 120 also includes a second folding assembly 122, the second folding assembly 122 is arranged on the side of the second side away from the first side, the second folding assembly 122 includes a second push plate 1221 and a second driving member 1222, the second push plate 1221 is connected to the second driving member 1222, and the second driving member 1222 drives the second push plate 1221 to push the second side to fold along the second direction Y toward the direction close to the first side. The second side is folded and formed by the second folding assembly 122, which has a simple structure and is easy to maintain. As an example, the second driving member 1222 can be a linear driving device that outputs a driving force along the second direction Y, for example, a servo electric cylinder with a push rod, which can push a short distance and a small force. For example, the second driving member 1222 can also be a linear drive, which can be electric (such as an electric linear slide, a servo motor with a linear guide), pneumatic or hydraulic drive, and is suitable for horizontal push applications that require precise control. For another example, the second driving member 1222 can also be a lifting device output along the second direction Y. As an example, the second driving member 1222 can still be a linear driving device as described above, but the direction of the output driving force has a certain angle with the first direction X. For example, the second driving member 1222 can output the driving force from the outside of the second side, in a direction at an angle of 45° to the second direction Y, or the second side can be folded inwardly to form. In short, as long as the second side can be pushed inwardly from the outside of the second side, it will be fine. The second folding assembly 122 can have the same or similar structure as the first folding assembly 121, and is relatively arranged on both sides of the paper box 200 along the second direction Y. When the end face of the paper box 200 is folded and formed, the first folding assembly 121 and the second folding assembly 122 can operate simultaneously, or they can operate one after another. In some cases, the operation one after another can cause the first side and the second side to partially overlap each other.

[0044] In one possible implementation, Figures 1 to 3 As shown, the second driving member 1222 is a rotary motor. The second push plate 1221 is fixed at the output end of the rotary motor, and the rotary motor drives the second push plate 1221 to push the second side surface to fold and form in a direction close to the second side surface. Selecting a rotary motor as the second driving member 1222 can make the second push plate 1221 not a fixed force application point when applying a driving force to the second side surface, but gradually move downward along the third direction Z from the initial force point as the second driving member 1222 drives the second push plate 1221 to rotate, so that the area receiving the driving force from the second side surface is larger and the force is more uniform, thereby avoiding the deformation of the second side surface of the paper box 200 caused by a single point of force, and reducing the occurrence of defective products.

[0045] Furthermore, the second push plate 1221 has a bending structure. Specifically, the second push plate 1221 has a connecting portion and an abutting portion that are interconnected. Among them, the connecting portion is used to be fixedly connected to the output end of the second driving member 1222, and the abutting portion is used to abut the second side surface. The bending structure refers to that the abutting portion and the connecting portion are not connected in a straight line, but have a certain angle or arc. The angle or arc is an angle or arc deflected in the direction in which the second side surface needs to be folded and formed. In this way, when the rotating motor drives the second push block to rotate and move toward the second side surface, the abutting portion gradually approaches the second side surface, and the contact range with the second side surface increases, such as Figures 1 to 3 As shown, when the abutting portion is perpendicular to the connecting portion, when the rotating motor drives the second push block to rotate until the connecting portion is parallel to the second direction Y, the abutting portion is parallel to the third direction Z, and the side walls of the abutting portion along the third direction Z all contact the second side surface, and the abutting area is large, so the second side surface can be better folded into shape.

[0046] In a feasible embodiment, the structures of the first folding assembly 121 and the second folding assembly 122 may also be different. For example, one folding assembly uses a rotary motor as a driving force output device, while the other folding assembly uses a linear drive device, which can also achieve the forming of the first side surface and the second side surface.

[0047] In a feasible implementation, the folding mechanism 120 includes a third folding assembly 123. The third folding assembly 123 is arranged on the side of the third side away from the fourth side 204. The third folding assembly 123 includes a third push plate 1231 and a third driving member 1232. The third push plate 1231 is connected to the third driving member 1232, and the third driving member 1232 drives the third push plate 1231 along the third direction Z to push the third side to fold in the direction close to the fourth side 204. The third side is folded and formed by the third folding assembly 123, which has a simple structure and is also easy to maintain. Figures 1 to 3 As shown, the third driving member 1232 can be a cylinder that outputs driving force along the third direction Z, and the third push plate 1231 is fixedly connected to the output end of the cylinder, and the length direction of the third push plate 1231 is arranged along the second direction Y. In this way, the third push block can approach the third side surface along the third direction Z under the drive of the cylinder to fold the third side surface into shape. Furthermore, the part of the third push block that abuts against the third side surface can be a flexible material, such as urethane, POM or high molecular polymer resin, so that the third push block can be in flexible contact with the third side surface when applying thrust to the third side surface, thereby reducing the risk of damage to the third side surface caused by extrusion and reducing the product defect rate.

[0048] In a feasible implementation, the folding mechanism 120 includes a fourth folding component 124, and the fourth folding component 124 is arranged on the side of the fourth side 204 away from the third side. The fourth folding component 124 includes a fourth push plate 1241 and a fourth driving member 1242, and the fourth push plate 1241 is connected to the fourth driving member 1242, and the fourth driving member 1242 drives the fourth push plate 1241 along the third direction Z to push the fourth side 204 to fold in the direction close to the third side. The fourth side 204 is folded and formed by the fourth folding component 124, and the structure is simple and easy to maintain. Furthermore, the third driving member 1232 is fixed on the loading mechanism 110. In this way, the position of the third driving member 1232 relative to the paper box 200 is fixed, the structure is stable, and the quality and effect of the forming of the paper box 200 can also be improved. Figures 1 to 3 As shown, the fourth driving member 1242 can be a cylinder that outputs a driving force in the fourth direction, and the fourth push plate 1241 is fixedly connected to the output end of the cylinder, and the length direction of the fourth push plate 1241 is arranged along the second direction Y. In this way, the fourth push block can approach the fourth side 204 along the fourth direction under the drive of the cylinder, and fold the fourth side 204 into shape. Further, the part of the fourth push block that abuts the fourth side 204 can be a flexible material, such as urethane, POM or high molecular polymer resin, so that the fourth push block can be in flexible contact with the fourth side 204 when applying a thrust to the fourth side 204, reducing the risk of damage to the fourth side 204 caused by squeezing, and reducing the product defect rate. Further, the fourth folding component 124 can be fixed in the center of the first folding component 121 and the second folding component 122, so that the end face of the carton 200 can be better shaped, ensuring the consistency of the folding and forming of the carton 200, and improving the product yield.

[0049] In a feasible implementation, the folding mechanism 120 further includes a fifth folding assembly 125, which is arranged on one side of the opening of the loading mechanism 110 along the axial direction of the paper box 200 in the first direction X, and includes a fifth push plate 1251 and a fifth driving member 1252, wherein the fifth push plate 1251 is connected to the fifth driving member 1252, and the fifth driving member 1252 drives the fifth push plate 1251 along the first direction X to push the fourth side surface 204 to fold in a direction close to the main body of the paper box 200. The fifth folding assembly 125 and the fourth folding assembly 124 fold the fourth side surface 204 in a direction close to the main body of the paper box 200 from two directions respectively.

[0050] Further, such as Figures 1 to 3As shown, the fifth push plate 1251 has a U-shaped structure, and the opening of the U-shaped structure faces the fourth side surface 204. In this way, the fifth push plate 1251 can better fit the fourth side surface 204 to fold the fourth side surface 204 into shape.

[0051] In a feasible implementation, the ear plug mechanism 130 includes an ear plug push plate 131 and an ear plug driver 132. The ear plug push plate 131 is connected to the ear plug driver 132. The ear plug driver 132 drives the ear plug push plate 131 along the first direction X to push the paper ear 205 to fold in the direction close to the ear seam. As an example, the ear plug push plate 131 can be sheet-shaped, and the width of the ear plug push plate 131 is less than or equal to the length of the paper ear 205 along the second direction Y, so that the ear plug push plate 131 can insert the ear into the ear seam under the drive of the ear plug driver 132. As an example, the ear plug driver 132 can be a linear drive device that outputs a driving force along the first direction X, for example, a servo electric cylinder with a push rod, which can push a short distance and a small force. For example, the ear plug driver 132 can also be a linear drive, which can be electric (such as an electric linear slide, a servo motor with a linear guide), pneumatic or hydraulic drive, suitable for horizontal push applications that require precise control. For another example, the ear plug driving member 132 may also be a linear module output along the first direction X.

[0052] In a feasible implementation, the ear insertion mechanism 130 further includes an ear pulling assembly 133. The ear pulling assembly 133 includes an ear pulling driving member 1331 and an ear pulling member 1332. The ear pulling member 1332 is connected to the ear pulling driving member 1331. When the fourth driving member 1242 drives the fourth push plate 1241 along the third direction Z to push the fourth side surface 204 to fold in a direction close to the third side surface, the ear pulling driving member 1331 drives the ear pulling member 1332 along the second direction Y to insert between the fourth side surface 204 and the third side surface, and cooperates with the ear insertion push plate 131 to fold the paper ear 205 relative to the fourth side surface 204. The paper ear 205 is connected to a side of the fourth side surface 204 close to the third side surface, and the ear pulling assembly 133 can prevent the fourth folding assembly 124 and the fifth folding assembly 125 from forming the paper ear 205 together when forming the fourth side surface 204, and the ear insertion push plate 131 cannot work. Further, the ear-pulling member 1332 can be arranged along the first direction X, the ear-pulling member 1332 can extend between the fourth side 204 and the main body of the paper box 200 under the drive of the ear-pulling member 1331, the height of the ear-pulling member 1332 is in the position of the paper ear 205 simultaneously, like this, when the fourth folding assembly 124 is folding the fourth side 204, the ear-pulling member 1332 can stop the paper ear 205 from approaching the paper box 200 main body with the fourth side 204, at this moment, the ear-plugging push plate 131 pushes the paper ear 205 again, then can be along the horizontal direction, paper ear 205 is inserted in the ear seam. As an example, the ear-pulling member 1331 can be the linear drive device outputting driving force along the second direction Y, for example, the servo electric cylinder with push rod can carry out the pushing of short distance, small strength. As an example, the ear-pulling member 1332 can also have the flexible structure of similar sponge cover. In this way, the contact area between the ear-pulling member 1332 and the paper ear 205 can be increased, and the effect of pulling the ear can be improved. At the same time, the flexible material or flexible contact can avoid damage to the paper ear 205 when pulling the ear, and reduce defective products.
