Description

Technical Field

[0001] The present invention relates to the technical field of packaging and transportation, and in particular to a printing and packaging lifting device and a method for using the same. Background Art

[0002] As packaging containers, packaging boxes effectively protect the contents and reduce the risk of damage during transport. Some special items require printed logos to ensure they meet transport requirements. In these cases, a printing and packaging lifting device is required to move the box lid under the printing equipment to print the logo.

[0003] The existing Chinese patent with authorization announcement number CN116620822B discloses a carton packaging and printing conveyor, including a conveyor belt assembly and two side frames, as well as a bearing rotation assembly and a side pressure correction assembly. When the carton moves on the conveyor belt assembly, the front end of the carton can push the bearing rotation assembly to rotate around the connection with the side frame; the lower sides of the two side pressure correction assemblies are connected by a correction spring, and each side frame is also provided with a blocking assembly, the blocking assembly is connected to the bearing rotation assembly and the rotating bearing rotation assembly can drive the blocking assembly to move on the cross plate, and the blocking assembly can limit the side pressure correction assembly from rotating around the connection with the side frame; the middle part of the blocking assembly is connected to the end of the cross plate by a reset spring; this invention transports the packaging box by belt conveyor, and the bearing rotation assembly can drive the side pressure correction assembly to push the carton from both sides with the help of the power of the carton's forward movement, thereby automatically correcting the position of the carton, which is convenient for subsequent printing of the carton.

[0004] However, the printing and packaging device has the following defects when used: 1. When existing conveyor belts are used to transport packaging boxes to the bottom of a printing device for printing, in order to ensure normal printing, they need to drive the printing device or packaging box to move up and down, as well as rotate, so that the printing device and packaging box can be brought close to each other and the angle of the packaging box can be adjusted according to the printing position. However, during these operations, the lifting, moving, and rotating of the packaging box takes a long time, which causes significant wear and tear on the drive source (which performs the lifting, moving, and rotating operations). Furthermore, when one drive source is mounted on the end of the shaft of another drive source, the pressure on the drive source at the bottom is greater, making the drive source at the bottom more susceptible to damage and shortening its service life. 2. When the existing device moves the packaging box to the bottom of the printing equipment for printing, in order to ensure that the packaging box does not deviate or shake during the lifting and movement, the packaging box needs to be fixed. Among them, the method of adsorbing the packaging box with a vacuum suction cup is a common fixing solution for the packaging box. However, in the actual process of the vacuum suction cup adsorbing and fixing the packaging box, the bottom of the packaging box will come into direct contact with the suction port on the surface of the vacuum suction cup. Impurities on the packaging box can easily reduce its adsorption force, resulting in the vacuum suction cup being unable to generate sufficient adsorption force. At the same time, if the suction port is used for a long time or exposed to harsh environments, the vacuum suction cup may age or be damaged, and its service life will be short. Summary of the Invention

Wherein, a guide plate is provided through the guide support rod, and oblique bodies are provided on the left and right sides of the guide plate.

[0015] The present invention also provides a method for using a printing and packaging lifting device, comprising the following steps: S1. Conveying packaging materials: When printing logos on packaging carton board materials, a mechanical robot first places the carton board materials on top of the belt conveyor assembly, and the belt conveyor assembly operates to convey the carton board materials horizontally; S2. Elastic positioning of materials: When the conveyed carton board material moves to the side of the side positioning support assembly, the side positioning support assembly performs elastic positioning on the conveyed carton board material to ensure that the carton board material moves evenly to the top of the packaging lifting mechanism; S3. Printing of material logo: When the carton board material moves to the top of the packaging lifting mechanism, the spiral lifting component is activated, driving the turnover adsorption component to rise and adsorb the carton board material. The adsorbed and fixed carton board material is then lifted and moved to the bottom of the printing equipment to print the logo. At the same time, when the carton board material is printed, the turnover adsorption component will drive the carton board material to rotate and adjust the position and angle of the logo printed on the carton board material surface. Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects: 1. In the printing and packaging lifting device and its use method, the upper rotating rod can be raised and lowered outside the intermediate rotating shaft to drive the material (packaging box cardboard) adsorbed and fixed by the vacuum suction plate to be raised and lowered, and the material (packaging box cardboard) is moved to the bottom of the printing equipment for printing. At the same time, the design of the external protrusion and recessed structure at the connection between the upper rotating rod and the intermediate rotating shaft ensures the stability of the upper rotating rod's lifting and movement outside the intermediate rotating shaft. When the intermediate rotating shaft rotates, it can synchronously drive the upper rotating rod and the material (packaging box cardboard) adsorbed on the top of the upper rotating rod to rotate (360 degrees). The lifting and coordinated rotation operations of the two complement each other and eliminate interference and conflict. While ensuring the stability of both operations, it can effectively reduce the degree of damage to the second drive source and the hydraulic drive source, effectively ensuring the service life of the device, and is suitable for long-term operation for printing operations such as lifting and rotating materials (packaging box cardboard); 2. In the printing and packaging lifting device and its use method, a suction spacer is connected to the top of the suction port inside the vacuum suction plate through a spring sheet. On the one hand, this can prevent the material (packaging box cardboard) from directly contacting the suction port of the vacuum suction plate, thereby protecting the vacuum suction plate and its suction port, extending the service life of the vacuum suction plate while reducing the probability of impurities on the material surface being directly extracted. On the other hand, a larger space for gas movement is left between the suction spacer and the vacuum suction plate. When the air in the suction spacer is extracted to form a higher negative pressure, the pressure difference between the suction cup and the material will also increase, and the adsorption force will also be strengthened, which can better fix the material (packaging box cardboard) and prevent it from falling off. 3. In the printing and packaging lifting device and its method of use, the guide plate installed on the top of the conveyor belt can guide and position the material (packaging box cardboard) in the conveying state, ensuring that the material (packaging box cardboard) transferred to the top of the vacuum suction plate will not deviate. When the vacuum suction plate is sucking the material (packaging box cardboard), the middle part of the material (packaging box cardboard) can be sucked. At the same time, the oblique body installed on the side of the guide plate can expand the space between the guide plate and the material before contact. The obliquely conveyed material has a buffer space to enter the vertical space (between the two guide plates), which minimizes damage to the material. 4. In the printing and packaging lifting device and its use method, a triangular guide head is installed at the end of the oblique body. This can reduce the contact area between the conveying material (packaging cardboard) and the material (packaging cardboard) when they come into contact and collide (due to the traction force of the conveyor belt). This ensures that the colliding material (packaging cardboard) is not easily deflected at a large angle, protecting the guided and positioned material (packaging cardboard). Simultaneously, multiple horizontally arranged oblique grooves reduce the force (friction) applied when the material collides with or rubs against the guide plate, making it easier for the material to be carried by the conveyor belt.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application. Example

[0020] See also Figures 1-11A printing and packaging lifting device includes a device frame 10; a belt conveyor assembly 20 installed on the top of the device frame 10; a packaging lifting mechanism 30 installed on the inner side of the belt conveyor assembly 20; a side positioning support assembly 40 installed at the top edge of the belt conveyor assembly 20, and the packaging lifting mechanism 30 includes: a basic bracket 301 installed at the inner center of the belt conveyor assembly 20; a spiral lifting assembly 302 installed inside the basic bracket 301 and extending to the top of the basic bracket 301; an intermediate rotating shaft 303 rotatably connected to the top center of the base bracket 301; an outer protrusion 304 installed on the outside of the intermediate rotating shaft 303; a recessed portion 305 slidably connected to the outside of the outer protrusion 304; an upper rotating rod 306 movably connected to the intermediate rotating shaft 303 through the recessed portion 305 and the outer protrusion 304; a turnover adsorption assembly 307 installed on the top of the upper rotating rod 306 and located above the spiral lifting assembly 302, and the top of the turnover adsorption assembly 307 adsorbs and fixes materials.

[0021] The operating principle is as follows: During the printing process of a logo on a material (packaging box cardboard), a robot grabs the material (packaging box cardboard) and loads it onto the top of the belt conveyor assembly 20, where it is then conveyed and moved. Once the material (packaging box cardboard) reaches above the base support 301, the spiral lift assembly 302 is activated to drive the rotating suction assembly 307 upward and downward to contact and absorb the material (packaging box cardboard), simultaneously moving the material (packaging box cardboard) below the printing device. The rotating suction assembly 307, which absorbs the material (packaging box cardboard), can be rotated 360 degrees by the intermediate shaft 303, adjusting the angle and position of the material (packaging box cardboard) for printing to meet different printing requirements. Among them, the rotation of the turnover adsorption component 307 and the operation of the spiral lifting component 302 are both completed by lifting and rotating on the same shaft end, which can reduce the degree of damage to the driving source while ensuring the stability of the rotating and lifting materials (packaging box cardboard), effectively ensuring the service life of the device, and is suitable for long-term and high-intensity operations.

[0022] Specific reference Figure 3 and Figure 4The belt conveyor assembly 20 includes: a frame body 201 installed on the top of the device frame 10 by screws; an outer protective cover 202 installed on the outer side of the frame body 201; a first driving source 203 installed on the side of the outer protective cover 202; a side transmission belt 204 connected to the output end of the first driving source 203 through a synchronous wheel; a conveying shaft 205 connected to the side transmission belt 204 through a synchronous wheel, wherein two frame bodies 201 are provided, and the two frame bodies 201 are connected by a metal rod 2011, and two conveying shafts 205 are provided, and the two conveying shafts 205 are respectively rotatably connected to the front and rear sides of the frame body 201, and a side positioning support assembly 40 is installed on the top of the frame body 201 by screws.

[0023] In this solution, a conveying gear 2051 is fixedly installed on the outer side of the conveying shaft 205 and is rotatably connected to the inside of the frame body 201. There are multiple conveying gears 2051, and the outer sides of two conveying gears 2051 are meshed and connected with conveying belts 2052, wherein the conveying belts 2052 are movably arranged inside the frame body 201, and the top support of the conveying belts 2052 is positioned with materials.

[0024] In the above solution, the first driving source 203 is preferably a servo motor.

[0025] In the printing and packaging lifting device of the present invention, when conveying material (packaging cardboard), the first drive source 203 is activated, driving the side drive belt 204 connected to the outer side of the output end of the first drive source 203 via a synchronous pulley. This in turn causes the conveyor shaft 205 connected to the inner side of the side drive belt 204 via a synchronous pulley to rotate. This rotation of the conveyor shaft 205 in turn drives the conveyor gear 2051 mounted on its outer side to rotate, causing the conveyor belt 2052 meshing with the outer side of the conveyor gear 2051 to move, transporting the material (packaging cardboard) that the top of the conveyor belt 2052 contacts.

[0026] Specific reference Figure 5 and Figure 6 The spiral lifting assembly 302 includes: a second driving source 3021 installed at an eccentric position inside the basic bracket 301; a main shaft 3022 connected to the output end of the second driving source 3021; ​​a lower transmission belt 3023 connected to the outside of the main shaft 3022 through a synchronous wheel; a reciprocating screw rod 3024 connected to the inside of the lower transmission belt 3023 through a synchronous wheel, wherein the lower transmission belt 3023 is rotatably connected to the bottom of the basic bracket 301, and the reciprocating screw rod 3024 is rotatably connected to the center inside the basic bracket 301.

[0027] In this solution, the outer side of the reciprocating screw 3024 is connected to the lifting slider 30241 through a ball bearing, and the lifting slider 30241 is slidably connected to the inside of the basic bracket 301. The left and right sides of the lifting slider 30241 are installed with L-shaped support arms 30242 by screws. The L-shaped support arms 30242 extend to the top of the basic bracket 301, wherein the top of the L-shaped support arm 30242 is installed with an upper bracket 30243 by screws. The upper bracket 30243 is arranged above the basic bracket 301, and an upper rotating rod 306 is movably provided inside the upper bracket 30243, and a turnover adsorption component 307 is provided on the top of the upper bracket 30243.

[0028] In the above solution, when the reciprocating screw 3024 rotates, the lifting slider 30241 connected to its outer side via a ball bearing will operate, causing the L-shaped support arm 30242, which is screw-mounted to the outer side of the lifting slider 30241, to move up and down. When the L-shaped support arm 30242 moves up and down, the upper bracket 30243 mounted on top of the L-shaped support arm 30242 will also move up and down, causing the turnover adsorption assembly 307 mounted on top of the upper bracket 30243 to also move up and down.

[0029] In the printing and packaging lifting device of the present invention, when the material (packaging box cardboard) needs to be lifted and lowered for printing, the second drive source 3021 is activated, driving the main shaft 3022 connected to the output end of the second drive source 3021 to rotate. The rotation of the main shaft 3022 in turn drives the lower transmission belt 3023, which is connected to the outer side of the main shaft via a synchronous pulley, causing the reciprocating screw 3024, which is connected to the inner side of the lower transmission belt 3023 via the synchronous pulley, to rotate.

[0030] Specific reference Figure 7 、 Figure 8 and Figure 9 The outer side of the intermediate rotating shaft 303 is connected to the transmission gear 3031 through the outer protrusion 304, and the transmission gear 3031 is rotatably connected to the center of the top of the base bracket 301, and the side of the transmission gear 3031 is meshedly connected with a toothed rod 3032, and the toothed rod 3032 is slidably connected to the eccentric part of the top of the base bracket 301, wherein the toothed rod 3032 is connected to the output end of the hydraulic drive source 3033, and the hydraulic drive source 3033 is installed at the eccentric part of the top of the base bracket 301; an annular body 3061 is installed at the center of the outer side of the upper rotating rod 306, and the outer side of the upper rotating rod 306 is movably connected to the mounting block 3062 through the annular body 3061, and the mounting block 3062 is installed at the center inside the upper bracket 30243.

[0031] In the printing and packaging lifting device of the present invention, when the upper bracket 30243 is raised or lowered, the upper rotating rod 306, connected to its inner side via the mounting block 3062, also moves. At this point, the upper rotating rod 306 is slidably connected to the exterior of the intermediate rotating shaft 303 via the recess 305 and the outer protrusion 304, ensuring that the intermediate rotating shaft 303 and the upper rotating rod 306 are always connected. To rotate the material (packaging cardboard), the hydraulic drive source 3033 is activated, driving the toothed rod 3032 connected to the output end of the hydraulic drive source 3033 to move, causing the transmission gear 3031 meshing with the toothed rod 3032 to rotate. The rotation of the transmission gear 3031 causes the intermediate rotating shaft 303 mounted on its inner side to rotate. The design of the recess 305 and the outer protrusion 304 allows the upper rotating rod 306 to rotate, which in turn drives the turnover suction assembly 307 and the material (packaging cardboard) to rotate.

[0032] In the present invention, the hydraulic drive source 3033 is preferably a linear electric cylinder.

[0033] Specific reference Figure 7 The turnover adsorption component 307 includes: an adsorption bracket 3071 installed on the top of the upper rotating rod 306; a hydraulic support system 3072 installed at the eccentric bottom of the adsorption bracket 3071, and the hydraulic support system 3072 is movably connected to the inside of the guide ring groove 3073; a vacuum adsorption disk 3074 installed at the bottom of the adsorption bracket 3071 and located on the inner side of the hydraulic support system 3072, and the top of the vacuum adsorption disk 3074 is installed inside the adsorption bracket 3071, wherein a plurality of hydraulic support systems 3072 are provided, and the guide ring groove 3073 is provided at the edge of the top of the upper bracket 30243, and a plurality of vacuum adsorption disks 3074 are provided, and the top of the vacuum adsorption disk 3074 adsorbs and fixes the material.

[0034] In the printing and packaging lifting device of the present invention, when the upper rotating rod 306 rotates, the suction bracket 3071 connected to its top also rotates, causing the material (packaging cardboard) held by the vacuum suction plate 3074 on top of the suction bracket 3071 to rotate. During this rotation, the hydraulic support system 3072 rotates synchronously, constantly supporting the suction bracket 3071 at various eccentric points, ensuring that the printed material (packaging cardboard) remains parallel.

[0035] Specific reference Figure 10 and Figure 11The side positioning support assembly 40 includes: a side baffle 401 installed at the top edge of the frame body 201 by screws; a guide support rod 402 slidably connected to the inside of the side baffle 401; an assembly ring 403 threadedly connected to the outside of the guide support rod 402; a guide plate 404 installed on the side of the assembly ring 403 by screws; a buffer spring 405 arranged between the side baffle 401 and the guide plate 404, and the buffer spring 405 is arranged on the outside of the guide support rod 402, wherein the guide support rod 402 is penetrated by a guide plate 404, and an oblique body 4041 is arranged on the left and right sides of the guide plate 404.

[0036] In the printing and packaging lifting device of the present invention, during the conveying process of the material (packaging cardboard), the conveying cardboard contacts the inclined body 4041 and is moved through the inclined body 4041 into the interior of the guide plate 404. The design of the guide plate 404 guides and positions the conveyed material (packaging cardboard), ensuring that the material (packaging cardboard) is horizontal and flat when it reaches the top of the turnover adsorption assembly 307. The guiding guide plate 404 can be moved to different positions on the guide support rod 402 via a threaded connection, allowing the distance between the two guide plates 404 to be adjusted according to actual needs, enabling the adjustment of the guide plates 404 at a specific distance. Example

[0037] See also Figures 1-11 A method for using a printing and packaging lifting device comprises the following steps: S1. Conveying packaging materials: When printing a logo on a carton board material for packaging, a mechanical robot first places the carton board material on top of the belt conveyor assembly 20, and the belt conveyor assembly 20 operates to convey the carton board material horizontally; S2. Elastic positioning of materials: When the conveyed carton board materials move to the side of the side positioning support assembly 40, the side positioning support assembly 40 performs elastic positioning processing on the conveyed carton board materials to ensure that the carton board materials are evenly moved to the top of the packaging lifting mechanism 30; S3. Printing the Material Logo: When the carton board material moves above the packaging lifting mechanism 30, the spiral lifting assembly 302 is activated, driving the turnover suction assembly 307 to rise and suck the carton board material. The suctioned and fixed carton board material is then lifted and moved to the bottom of the printing device to print the logo. Simultaneously, while the carton board material is being printed, the turnover suction assembly 307 drives the carton board material to rotate, adjusting the position and angle of the logo printed on the carton board surface. Example

[0038] Based on the above embodiment, it was discovered during use that when the oblique body 4041 guides the material (packaging cardboard), its contact area with the packaging cardboard is large, resulting in greater horizontal or oblique impact forces on the material (packaging cardboard). This impact force can cause the material to deflect significantly, leading to a significant obstruction when the material (packaging cardboard) moves between the two guide plates 404 due to its steep slope. Furthermore, direct contact between the material (packaging cardboard) and the guide plates 404 can easily damage the angled portion of the packaging cardboard, affecting the sealing performance of the assembled packaging cardboard.

[0039] For this purpose, refer specifically to Figure 12 A plurality of triangular guide heads 4042 are installed on the inner bottom of the oblique body 4041 by screws, and a plurality of oblique grooves 4043 are opened on the surface of the oblique body 4041 , and the oblique grooves 4043 are arranged on the side of the triangular guide head 4042 .

[0040] In the printing and packaging lifting device of the present invention, the design of multiple triangular guide heads 4042 allows the tapered contact surfaces of the triangular guide heads 4042 to reduce the contact area with the material (packaging box cardboard). This in turn reduces the angle at which the material (packaging box cardboard) deflects due to collision, ensuring that the material (packaging box cardboard) can be moved between the two guide plates 404 at a smaller deflection angle. This reduces the likelihood of jams during positioning and conveying via the guide plates 404. Furthermore, the probability of collisions between the guide plates 404 and the material at an angle is reduced, minimizing damage to the material. Example

[0041] Based on the above embodiment, it was found during use that when the material (packaging box cardboard) is directly adsorbed and fixed, the adsorption port 30741 of the vacuum adsorption plate 3074 is likely to come into direct contact with impurities or oil stains at the bottom of the material (packaging box cardboard), resulting in poor adsorption and fixing effect of the vacuum adsorption plate 3074 on the material (packaging box cardboard).

[0042] For this purpose, refer specifically to Figure 13 A spring sheet 50 is installed on the side of the suction port 30741 inside the vacuum suction disk 3074. The top of the spring sheet 50 is in contact with a suction spacer 501 movably connected to the surface of the vacuum suction disk 3074. A plurality of suction openings 502 are provided inside the suction spacer 501. The suction openings 502 and the suction port 30741 are in the same vertical plane, and a gap is left between the vacuum suction disk 3074 and the suction spacer 501.

[0043] In the printing and packaging lifting device of the present invention, the weight of the material (packaging box cardboard) automatically drives the suction spacer 501 in contact with the material (packaging box cardboard) downward, bringing it closer to the suction port 30741 of the vacuum suction plate 3074. Simultaneously, the vacuum extraction force generated by the suction port 30741 is first transmitted through the suction spacer 501 to the surface of the material (packaging box cardboard). This prevents direct contact between the material (packaging box cardboard) and the suction port 30741, reducing the likelihood of impurities or oil from the material (packaging box cardboard) entering the vacuum suction plate 3074. This improves the suction and fixation of the material (packaging box cardboard) while ensuring the service life of the vacuum suction plate 3074. Furthermore, the gap created between the suction spacer 501 and the vacuum suction plate 3074 provides more space for the vacuum suction plate 3074 to extract air for suction, thereby increasing the vacuum level within the vacuum suction plate 3074 and strengthening the suction force between the vacuum suction plate 3074 and the material.

[0044] Without limitation, any person skilled in the art who is familiar with the technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the protection scope of the present invention.
