Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to an automatic screen printing and folding box forming machine. Background Art

[0002] In the process of production and sales of commodities, various packaging designs are often adopted. Among them, using a folding carton for packaging is one of the most common methods. The traditional folding carton forming is carried out by manual processing, that is, the designed graphic logo is printed on the original carton material first, and then the original carton material is manually folded and glued into a finished carton. Such a processing method not only has low efficiency, but also it is difficult to guarantee the quality of the formed carton. In addition, at present, there are also a small number of cartons produced by automated equipment, but the printing and folding of most cartons are completed on different equipment, and cumbersome transfer operations are required. Moreover, most of the traditional folding equipment can only fold single-layer sidewall cartons. When folding double-layer sidewall cartons, multiple different folding mechanisms arranged in sequence are required. First, the cardboard is folded into a box shape, and then it is sent to the next folding mechanism through a conveying device to fold the erected sidewalls inward to be horizontal, and then it is sent to the subsequent folding mechanism to squeeze and fold the horizontal sidewalls inward to be vertically extended downward.

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0021] As Figures 1 to 7As shown in the figure, this is an automatic screen printing folding box forming machine 100 of the present utility model, which includes a processing table 10 and a feeding assembly 20, a feeding assembly 30, a screen printing assembly 40, a drying assembly 50, a folding box assembly 60 and a discharging assembly 70 installed on the processing table 10. Among them, the feeding assembly 30 runs across the processing table 10, and the feeding assembly 20, the screen printing assembly 40, the drying assembly 50, the folding box assembly 60 and the discharging assembly 70 are arranged in sequence along the feeding assembly 30. It can be understood that in the present utility model, there are also several air sources, driving devices and automatic control devices. Since they are all conventional technical contents in this technical field, they will not be described in detail here.

[0022] The feeding assembly 20 includes a feeding bin 21 and a feeding suction cup 22. The feeding bin 21 is arranged above the feeding assembly 30 and includes several storage plates 211. The several storage plates 211 enclose to form the feeding bin 21. The bottom of the feeding bin 21 is hollowed out and communicated with the feeding assembly 30 below. The feeding suction cup 22 is arranged below the feeding assembly 30 and corresponds to the feeding bin 21 up and down. The feeding suction cup 22 can move up and down and stretch through the bottom of the feeding assembly 30 and the feeding bin 21. When feeding is required, only the original paper box material needs to be placed into the feeding bin 21. Then the feeding suction cup 22 will rise to adsorb and grab the original paper box material at the bottom of the feeding bin 21, and then drive the original paper box material to descend and place it on the feeding assembly 30. In this embodiment, there are paper box creases on the original paper box material. Therefore, when the feeding suction cup 22 sucks and pulls the original paper box material downward, the original paper box material can be deformed along the crease, so as to facilitate material taking.

[0023] The feeding assembly 30 includes a feeding slide rail 31, a lifting slide seat 32, a bearing plate 33, a support column 34 and an auxiliary beam 35. The feeding slide rail 31 is installed on the processing table 10. The lifting slide seat 32 is clamped on the feeding slide rail 31 and can slide horizontally and lift vertically. The bearing plate 33 is installed at the upper end of the lifting slide seat 32. The support columns 34 are all fixedly erected on the processing table 10. The auxiliary beam 35 is installed at the upper end of the support columns 34 and is located on both sides of the bearing plate 33.

[0024] When the original paper box material is located on the feeding assembly 30, the lifting slide seat 32 and the bearing plate 33 will automatically drive the original paper box material to be horizontally transported along the feeding slide rail 31. During the transportation process, the middle part of the original paper box material is supported by the bearing plate 33, and the two sides of the original paper box material are supported by the auxiliary beam 35. When the lifting slide seat 32 slides along the slide rail 31, it will synchronously drive the bearing plate 33 and the original paper box material supported by the bearing plate to be transported from one side to the other side. Then the lifting slide seat 32 will descend along the slide rail 31 to return to the starting point to continue the next transportation; thus completing a series of subsequent processing such as screen printing, drying and folding box forming.

[0025] The screen printing assembly 40 includes a positioning module 41 which is arranged on both sides of the feeding assembly 30. The positioning module 41 includes a plurality of horizontal carriages 411, telescopic cylinders 412 and limit blocks 413. The plurality of horizontal carriages 411 are all installed on the processing table 10 and are respectively located on both sides of the feeding assembly 30. The plurality of telescopic cylinders 412 are respectively horizontally and obliquely installed on the plurality of horizontal carriages 411 and can slide back and forth driven by the horizontal carriages 411. The telescopic cylinders 412 can also move and expand and contract in the inclined direction. The plurality of limit blocks 413 are respectively installed at the inner ends of the plurality of telescopic cylinders 412. When the original paper box material is transported to the screen printing assembly 40, the positioning module 41 will start to work. By the sliding and expansion and contraction of the horizontal carriages 411 and the telescopic cylinders 412, the limit blocks 413 are driven to push inward, and then the possible skew problem of the original paper box material is corrected by the limit blocks 413.

[0026] The screen printing assembly 40 further includes a lifting module 42 which is arranged below the feeding assembly 30. The lifting module 42 includes a lifting frame 421 and a lifting suction cup 422. The lifting frame 421 is installed below the feeding frame and can move up and down. The lifting suction cup 422 is installed on the lifting frame 421. When the original paper box material is correctly aligned on the feeding assembly 30, the lifting frame 421 will drive the lifting suction cup 422 to rise. The lifting suction cup 422 adsorbs the original paper box material and drives it to continue to be transported upward.

[0027] The screen printing assembly 40 further includes a screen printing module 43 which is arranged above the feeding assembly 30. The screen printing module 43 includes a mounting frame 431, a screen printing stencil 432, a sliding robotic arm 433 and a screen printing squeegee 434. The mounting frame 431 stands on the processing table 10 and is located on one side of the feeding assembly 30. The screen printing stencil 432 is installed on the mounting frame 431 and is located above the feeding assembly 30. The screen printing stencil 432 is also arranged corresponding to the lifting module 42 up and down. The sliding robotic arm 433 is slidably installed on the mounting frame 431. The sliding robotic arm 433 can slide horizontally and lift vertically. The screen printing squeegee 434 is installed at the lower end of the sliding robotic arm 433 and is located above the screen printing stencil 432. The rising original paper box material finally abuts and fits against the bottom of the screen printing stencil 432. Then the sliding robotic arm 433 drives the screen printing squeegee 434 to scrape along the upper surface of the screen printing stencil 432, so that the screen printing ink is printed on the surface of the original paper box material along the preset stencil pattern.

[0028] The drying component 50 includes a drying furnace (not shown in the figure) and a heater (not shown in the figure). The drying furnace is designed in an "n" shape and is installed on the processing table 10 from top to bottom, covering the upper part and both sides of the feeding component 30. The heater is installed on the inner side wall of the drying furnace. The paper box raw material with the ink pattern printed on it is driven by the lifting component and placed back on the feeding component 30 to continue transmission. When it enters the drying component 50, the high temperature generated by the heater will evaporate the moisture of the ink pattern, so that the silk-screened pattern is completely cured on the surface of the paper box raw material.

[0029] The box folding component 60 includes a base 61, a material grabbing robotic arm 62, a long side folding cylinder 63, an ear folding cylinder 64 and a short side folding cylinder 65. The base 61 is installed below the feeding component 30. The material grabbing robotic arm 62 is installed above the feeding component 30 and is arranged corresponding to the base 61 up and down. A material grabbing suction cup (not shown in the figure) is also provided at the bottom of the material grabbing robotic arm 62. The long side folding cylinder 63, the ear folding cylinder 64 and the short side folding cylinder 65 are all installed below the feeding component 30. Among them, the long side folding cylinder 63 is symmetrically arranged on both long side sides of the base 61, and a limiting folding plate 631 is also provided inside the long side folding cylinder 63. The ear folding cylinders 64 are respectively arranged in parallel on the outer sides of the long side folding cylinders 63. The short side folding cylinders 65 are respectively symmetrically arranged on both short side sides of the base 61.

[0030] After the paper box raw material is dried and processed, it continues to be sent to the box folding component 60 by the feeding component 30. At this time, the material grabbing robotic arm 62 first grabs the paper box raw material through the material grabbing suction cup and presses it down onto the base 61. Before the paper box raw material is pressed down, the long side folding cylinder 63 will drive the limiting folding plate 631 to adjust the distance to match the width of the paper box. When the paper box raw material is pressed down, its long side will be limited by the limiting folding plate 631 and thus bend upward until it is folded into the long side of the paper box. Then the ear folding cylinder 64 is activated to push and bend the ear structure outside the long side of the paper box. Then the short side folding cylinder 65 pushes the short side to bend. Finally, the material grabbing robotic arm 62 presses down again to fold the short side secondarily and fit it to the inner side wall of the paper box, so that the paper box product is finally formed.

[0031] The blanking component 70 includes a blanking push rod 71 and a blanking chute 72. The blanking push rod 71 is installed on one side of the bottom of the material grabbing robotic arm 62. The blanking chute 72 is connected to the end of the feeding component 30 and is arranged horizontally opposite to the blanking push rod 71. The formed paper box product is lifted by the base and returns to the feeding component 30 again, and is further pushed backward by the blanking push rod 71 until it enters the blanking chute 72. The inclined blanking chute 72 enables the paper box product to slide out of the equipment under the action of its own gravity, realizing simple and rapid blanking operation.

[0032] In summary, the beneficial effects of the automatic screen printing folding box forming machine 100 of the present utility model are as follows: The folding box component 60 is designed to automatically fold and form the paper box, which greatly improves the forming efficiency of the paper box compared with the manual folding and forming method, and at the same time, the quality of the formed paper box is more stable and reliable; The feeding component 20 and the material feeding component 30 are designed to realize automatic feeding during the folding box process, further improving the automation ability and processing and forming efficiency of the equipment; The screen printing component 40 is designed to automatically screen print graphic marks on the paper box, and cooperate with the drying component 50 to quickly dry and form the screen printing, which not only improves the forming efficiency of the paper box again, but also greatly improves the printing quality and aesthetics of the paper box; The present utility model has strong practicability and has strong promotion significance.
