Description

Technical Field

[0001] The present invention relates to the technical field of packaging processing, in particular to a fast gluing machine for carton processing. Background Art

[0002] Gluing machines, also known as gluing machines, are often used in carton processing procedures. In the prior art, there is a composite carton made of cardboard and foam lining bonded to each other. The processing flow is: first, glue is sprayed on the part of the cardboard to be folded by a gluing machine, and then the foam lining is placed in the center of the cardboard. The cardboard is then manually folded 90 degrees to fit the cardboard and the foam lining, and the cardboard and the foam lining are bonded as a whole by glue. In the process of folding the cardboard, the folded part of the cardboard will be reset due to elasticity, so that the cardboard and the foam lining are separated, so that the cardboard needs to be pressed manually multiple times to ensure the fit between the cardboard and the foam lining, which prolongs the bonding time of the cardboard and the foam lining and reduces the efficiency of the bonding and forming of the two. Moreover, when the edge of the cardboard is warped, the sprayed glue will be unevenly distributed on the cardboard, making the glue thickness at the edge thinner, so that the edge of the carton is more easily separated from the foam lining, reducing the bonding quality of the glue.

[0019] The driving assembly includes a first driving member 201, a connecting plate 202, a second driving member 203 and a third driving member 204; the first driving member 201 is fixedly connected to the fixed platform 1, and the first driving member 201 is an electric push rod; the telescopic end of the first driving member 201 is fixedly connected to the connecting plate 202; the connecting plate 202 is in the shape of a cuboid; a second driving member 203 is fixedly connected to each of the front, rear, left and right side surfaces of the connecting plate 202, and the second driving member 203 is an electric push rod; the telescopic end of each second driving member 203 is fixedly connected to the adjacent limiting plate 3; the bottom surface of the connecting plate 202 is fixedly connected to the third driving member 204, and the third driving member 204 is an electric push rod; the telescopic end of the third driving member 204 is fixedly connected to the glue spraying frame 4.

[0020] Furthermore, in order to prevent the cardboard 6 from shifting during subsequent folding, two limiting blocks 2002 are provided on each rotating plate 2.

[0021] The thickness of the limiting block 2002 is set to be less than the thickness of the cardboard 6.

[0022] It also includes an auxiliary separation assembly; the auxiliary separation assembly includes a fourth driving member 205, a fixed frame 206 and an electromagnet 208; two symmetric fourth driving members 205 are fixedly connected to the fixed platform 1, and the fourth driving member 205 is an electric push rod; the telescopic ends of all the fourth driving members 205 are commonly fixedly connected to the fixed frame 206; the lower side of the fixed frame 206 is a rectangular strip frame; electromagnets 208 are installed at the four corners of the rectangular strip frame; each electromagnet 208 is magnetically adsorbed to the adjacent connecting block 5.

[0023] Furthermore, in order to reduce the friction between the limiting plate 3 and the connecting block 5 and the folding part 6001, the surfaces of all the limiting plates 3 and the connecting blocks 5 are set to be smooth surfaces.

[0024] Furthermore, in order to facilitate the limiting plate 3 to be better inserted into the foam lining 7, the bottom surface of the limiting plate 3 is the lower surface 3002, and a chamfer is provided on the side of the lower surface 3002 away from the connecting plate 202.

[0025] The following is a detailed description of the processing process of the carton composed of the cardboard 6 and the foam lining 7: First, manually place the cardboard 6 at the center of the fixed platform 1. The folding parts 6001 of the cardboard 6 are respectively placed on the corresponding rotating plates 2, and the edges of the folding parts 6001 are limited by the limit blocks 2002 on the rotating plates 2, so as to facilitate the accurate placement of the cardboard 6 by the staff and avoid the displacement of the cardboard 6 during subsequent folding. It should be noted that at this time, the electromagnet 208 is in a non-magnetized state, there is no magnetic attraction between the electromagnet 208 and the connecting block 5, and at this time, the four limit plates 3 and the four connecting blocks 5 jointly form a rectangular frame through magnetic attraction. Subsequently, control the first driving member 201 to drive the connecting plate 202 and its connecting parts to move downward, so that the limit plates 3 and the connecting blocks 5 move downward to fit the upper surface of the cardboard 6, and the lower surface 3002 of the limit plate 3 presses on the folding line of the cardboard 6. Then, control the micro motors on the fixed platform 1 to drive their respective rotating plates 2 to rotate upward, so as to drive the folding parts 6001 to fold upward. At this time, the folding state of the cardboard 6 is as Figure 4 shown. Note that by pressing the lower surface 3002 of the limit plate 3 on the folding line of the cardboard 6, the flatness of the folding part 6001 during folding can be ensured, and the situation of folding line deviation can be avoided. If the edge of the cardboard 6 is warped in the initial state as Figure 12 shown, when the rotating plate 2 rotates 90 degrees to a vertical state, at this time, the folding part 6001 is jointly clamped and flattened by the corresponding rotating plate 2 and the limit plate 3, so that the folding part 6001 fits the rotating plate 2, and control the external air pump to pump air out of the cavity in the rotating plate 2 to generate suction at the suction holes 2001, so that the folding part 6001 is flatly adsorbed on the rotating plate 2 to ensure the uniformity of subsequent glue spraying. Thus, the bending of the cardboard 6 and the correction of the warped edge part are realized. Here, it should be noted that when the folding part 6001 is folded 90 degrees, two adjacent folding parts 6001 are mutually attached, and the four rotating plates 2 are mutually attached to form a closed loop. Moreover, the thickness of the limit block 2002 is less than that of the cardboard 6 to avoid the collision of the limit block 2002 when the rotating plate 2 folds, and ensure that the rotating plate 2 folds in place.

[0026] Subsequently, the glue spraying process is carried out. After the folding part 6001 is folded by 90 degrees, at this time, the limiting plate 3 is attached to the adjacent folding part 6001. Control the first driving member 201 to drive the connecting plate 202 and its connecting parts to move upward, so that the limiting plate 3 moves upward until it disengages from the upper surface of the cardboard 6. At the same time, control the third driving member 204 to drive the glue spraying frame 4 and the glue spraying valve 4001 to move downward, so that the glue spraying frame 4 moves downward until it protrudes from the lower surface 3002 of the limiting plate 3. Then control the external glue supply device to supply glue to the glue spraying valve 4001, so that the glue is sprayed onto the folding part 6001 through the glue spraying valve 4001. Here it is noted that the glue can be sprayed in the form of a fan-shaped spray through the glue spraying valve 4001, and by spraying glue together with multiple glue spraying valves 4001 on the same side, it can ensure that the side of the folding part 6001 facing the limiting plate 3 can be sprayed in place, avoiding missed spraying. During the glue spraying process, the first driving member 201 drives the limiting plate 3 and the glue spraying valve 4001 to continuously move upward until the glue is sprayed to the uppermost side of the folding part 6001. At this time, control the glue spraying valve 4001 to stop spraying glue, and at the same time control the first driving member 201 to drive the limiting plate 3 and the glue spraying valve 4001 to continue to move upward, so that the limiting plate 3 disengages from the folding part 6001. Thus, the glue spraying process for the cardboard 6 is completed. Here it is noted that by setting the surfaces of the limiting plate 3 and the connecting block 5 to be smooth surfaces, the friction between the limiting plate 3 and the connecting block 5 and the folding part 6001 is reduced, avoiding the folding part 6001 being driven to move upward when the limiting plate 3 and the connecting block 5 move upward.

[0027] Subsequently, the bonding process of the foam lining 7 and the cardboard 6 is carried out. After the glue spraying is completed, the cardboard 6 and the rotating plate 2 still remain Figure 5The folding parts 6001 on the front and rear sides are folded to 100 degrees, so that the folded parts 6001 on the front and rear sides are folded to 100 degrees, and the folded parts of the cardboard 6 are over-bent, thereby eliminating the subsequent resetting of the cardboard 6 due to elasticity. Then, the rotating plate 2 is controlled to drive the folding parts 6001 to rotate away from the connecting plate 202, so that the folding parts 6001 on the front and rear sides are folded to 80 degrees, forming an inverted eight-shaped arrangement. Similarly, according to the same steps above, the folding parts 6001 on the left and right sides are folded to 100 degrees and then to 80 degrees by the rotating plate 2. Then, the staff places the foam lining 7 in the center of the cardboard 6, and then controls the rotating plate 2 to rotate. Plate 2 drives the corresponding folding portion 6001 to fold to 90 degrees, so that the folding portion 6001 is fitted with the foam lining 7, and the folding portion 6001 and the foam lining 7 are bonded together into a whole through glue. Since the folding part of the cardboard 6 is folded in advance, the elasticity of the folding part of the cardboard 6 is eliminated, and the folding part of the cardboard 6 is prevented from resetting and rotating due to the elasticity, which causes the cardboard 6 to separate from the foam lining 7. Therefore, there is no need to press the cardboard 6 for a long time, which improves the bonding efficiency of the cardboard 6 and the foam lining 7, and completes the bonding process of the foam lining 7 and the cardboard 6. It should be noted that when the cardboard 6 and the foam lining 7 are fitted together, the external air pump is controlled to stop pumping air into the rotating plate 2, so that the rotating plate 2 is easy to separate from the folding portion 6001.

[0028] In summary, compared with conventional gluing machines, during the gluing process, the cardboard 6 is folded by the cooperation of the rotating plate 2, the limiting plate 3 and the connecting block 5, thereby eliminating the elasticity of the folded part of the cardboard 6, thereby eliminating the need to press the cardboard 6 for a long time, thereby improving the bonding efficiency between the cardboard 6 and the foam lining 7. In addition, the raised part of the cardboard 6 is flattened and corrected by the rotating plate 2, the limiting plate 3 and the connecting block 5, thereby ensuring that the folded part 6001 is in a flat state before spraying glue, thereby ensuring that the glue is evenly sprayed on the surface of the folded part 6001, thereby ensuring that the glue thickness of the raised part of the cardboard 6 is uniform, thereby improving the bonding quality of the glue.

[0029] On this basis, considering that the foam lining 7 is a porous structure and the glue needs to penetrate into the pores of the foam lining 7 to form a firm and reliable bonding surface, but it takes a long time for the glue to penetrate into the pores of the foam lining 7. Therefore, after the limiting plate 3 moves upward and disengages from the folding part 6001, the control limiting plate 3 continues to move upward so that the connecting block 5 fits against the adjacent electromagnet 208. At the same time, the electromagnet 208 is controlled to be magnetized, generating a magnetic attraction force between the electromagnet 208 and the connecting block 5. During this process, the staff places the foam lining 7 on the cardboard 6, and then controls the first driving member 201 to drive the limiting plate 3 to move downward. Here, it should be noted that the magnetic attraction force between the electromagnet 208 and the connecting block 5 is greater than the suction force between the connecting block 5 and the limiting plate 3, so that the connecting block 5 is in a static state. As the limiting plate 3 continues to move downward until the limiting plate 3 disengages from the adjacent connecting block 5, then the telescopic end of the second driving member 203 is controlled to retract, so that all the limiting plates 3 move toward the side close to the connecting plate 202 until the four limiting plates 3 fit together, and the outer shape after the four limiting plates 3 fit together is adapted to the inner shape of the foam lining 7. Then, the third driving member 204 is controlled to lift the glue spraying frame 4 and the glue spraying valve 4001 to a position where the lowest side of it is higher than the lower surface 3002. Then, the first driving member 201 is controlled to drive the four limiting plates 3 to move downward, so that the four limiting plates 3 are inserted into the hollow part of the foam lining 7 until the lower surface 3002 of the limiting plate 3 fits against the upper surface of the cardboard 6. Here, it should be noted that since a chamfer is provided on the side of the lower surface 3002 away from the connecting plate 202, it is convenient for the limiting plate 3 to be inserted into the hollow part of the foam lining 7. And according to the steps in the above bonding process, the folding part 6001 is brought into contact with the foam lining 7 through the rotating plate 2. Subsequently, the telescopic end of the second driving member 203 is controlled to extend, so that the limiting plate 3 moves away from the side of the connecting plate 202, so that the limiting plate 3 presses the foam lining 7, and the foam lining 7 presses the folding part 6001, thereby accelerating the penetration of the glue into the pores of the foam lining 7, and further helping to improve the bonding strength of the glue, so as to ensure that the cardboard 6 and the foam lining 7 will not separate during the blanking process, and improve the bonding quality.

[0030] After the limiting plate 3 presses the foam lining 7, the second driving member 203 is controlled to drive the limiting plate 3 to reset, so that the four limiting plates 3 fit together again. Then, the first driving member 201 is controlled to drive the limiting plate 3 to move upward. Note that at this time, the upper surface of the foam lining 7 is manually pressed to prevent the foam lining 7 from moving upward when the limiting plate 3 moves. Until the limiting plate 3 disengages from the foam lining 7, the cardboard 6 and the foam lining 7 are manually removed, and a new cardboard 6 is placed on the fixed platform 1 to perform a new round of glue spraying and bonding processes for the cardboard 6.

[0031] Embodiment 2: On the basis of Embodiment 1, referring to Figures 2 - 3 、 Figure 7 andFigure 8 As shown, each limiting plate 3 is internally provided with a cavity; a plurality of air injection holes 3001 are formed on the side surface of each limiting plate 3 facing the adjacent rotating plate 2, and the air injection holes 3001 are communicated with the corresponding internal cavity; the internal cavity of each limiting plate 3 is communicated with an external air pump.

[0032] It further includes a servo motor 207; each electromagnet 208 is arranged to be rotatably connected to the fixed frame 206; four servo motors 207 are fixedly connected to the fixed frame 206; the output end of each servo motor 207 is fixedly connected to the adjacent electromagnet 208; the electromagnet 208 is driven to rotate by the servo motor 207.

[0033] It further includes a gasket 209; a gasket 209 is arranged at the connection between each electromagnet 208 and the fixed frame 206; the gasket 209 is made of flexible rubber material.

[0034] Considering that when the foam lining 7 squeezes the folding part 6001, glue is likely to overflow from the edge of the contact surface between the foam lining 7 and the folding part 6001, resulting in waste of glue and a decrease in bonding quality. Therefore, after the four limiting plates 3 are inserted into the hollow part of the foam lining 7, as an alternative process to the limiting plate 3 squeezing the foam lining 7, with the view from right to left as the reference, at this time, control the left servo motor 207 to drive the two left electromagnets 208 and the connecting block 5 to rotate clockwise by 180 degrees, and control the right servo motor 207 to drive the two right electromagnets 208 and the connecting block 5 to rotate counterclockwise by 180 degrees. After the rotation is completed, the electromagnet 208 and the fixed frame 206 together form a closed rectangular strip frame, and then control the fourth driving member 205 to drive the electromagnet 208 and the fixed frame 206 to move downward, so that the closed rectangular strip frame fits on the upper surface of the foam lining 7. Its three-dimensional state is as Figure 10 shown, and the sectional structure is as Figure 11 shown. At this time, the rotating plate 2, the limiting plate 3, the cardboard 6, the fixed frame 206 and the electromagnet 208 together form a temporary sealing cavity, which wraps the foam lining 7 inside. Subsequently, control the external air pump to continuously pump air from the limiting plate 3 for 10 seconds, so that suction is generated at the air injection holes 3001, thereby pumping out the air in the pores of the foam lining 7, reducing the air pressure in the pores of the foam lining 7, and thus forming a negative pressure. In this way, it can accelerate the penetration of the glue into the pores of the foam lining 7, which helps to improve the bonding strength of the glue. It should be noted here that the gap between the electromagnet 208 and the fixed frame 206 is filled with the gasket 209 to improve the sealing performance of the temporary sealing cavity to ensure the negative pressure effect on the pores of the foam lining 7. In addition, the gasket 209 is made of flexible rubber material, ensuring the smooth rotation of the electromagnet 208.

[0035] After the air extraction of the limit plate 3 is completed, control the external air pump to convey air to the limit plate 3 to restore the air pressure in the temporary sealing cavity, and then control the first driving member 201 to drive the limit plate 3 to move upward to the initial position, and control the fourth driving member 205 to drive the fixed frame 206 and the electromagnet 208 to move upward to the initial position. At this time, the limit plate 3, the fixed frame 206 and the electromagnet 208 are all separated from the foam lining 7, and control the rotating plate 2 to rotate to the initial horizontal state. Subsequently, manually remove the cardboard 6 and the foam lining 7, and place a new cardboard 6 on the fixed platform 1 to perform a new round of glue spraying and bonding processes for the cardboard 6.
