Description

Technical Field

[0001] This utility model relates to the field of packaging box printing technology, and in particular to a packaging box printing device with a positioning mechanism. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, etc. The functions of packaging boxes include: ensuring the safety of products during transportation and enhancing the product's grade.

[0003] Currently, most existing positioning mechanisms for packaging box printing still require manual adjustment of each box to the correct position during printing. This results in low printing efficiency and high labor costs. Furthermore, some boxes may have dust or other impurities adhering to their surfaces. If these are not removed before printing, the dust will eventually fall off the box, leading to missing printed content and significantly reducing print quality. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a packaging box printing device with a positioning mechanism, which has the advantages of good printing quality and high printing efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A packaging box printing apparatus with a positioning mechanism includes a conveyor frame, a conveying mechanism inside the conveyor frame, two guide frames symmetrically arranged on the inner side of the conveyor frame with inclined front ends, connecting shafts passing through both sides of the conveyor frame, one end of each connecting shaft being fixedly connected to one side of the two guide frames, and the other end of each connecting shaft being connected to a movable seat, a moving mechanism on the conveyor frame connected to the two movable seats, a frame fixedly mounted at the upper end of the conveyor frame, a first electric push rod mounted on the top of the frame, a frame body inside the frame, and the output shaft of the first electric push rod being fixedly connected to the upper end of the frame body. Next, a hollow column is rotatably connected to the lower end of the frame, and a turntable is connected to the lower end of the hollow column. Several bristles are connected to the lower end of the turntable. A cavity is provided inside the turntable, and the hollow column is connected to the cavity. Several air holes are opened at the lower end of the turntable, and all of the air holes are connected to the cavity. A blower is provided at the top of the frame. A connecting pipe is rotatably connected to the upper end of the hollow column, and a flexible hose is connected between the connecting pipe and the blower. A rotating mechanism is provided on the frame, and the rotating mechanism is connected to the hollow column. A second electric push rod is also installed at the top of the frame. A printing plate is provided on the inner side of the frame, and the output shaft of the second electric push rod is fixedly connected to the upper end of the printing plate.

[0006] Preferably, the conveying mechanism includes a first motor installed on one side of the conveyor frame, two rotating rollers passing through the inner side of the conveyor frame, the output shaft of the first motor being fixedly connected to one end of one of the rotating rollers via a coupling, and a conveyor belt being sleeved between the two rotating rollers.

[0007] Preferably, the moving mechanism includes a rotating shaft, mounting brackets are fixedly provided on both sides of the conveying frame, and through slots are provided on both sides of the conveying frame. Two through slots are respectively passed through the two ends of the rotating shaft and are rotatably connected to the two mounting brackets. A second motor is installed on one side of the mounting bracket, and the output shaft of the second motor is fixedly connected to one end of the rotating shaft. Two external threads with opposite thread directions are provided on the rotating shaft. Threaded holes are respectively provided on the lower sides of the two moving seats and are threaded through the rotating shaft via the external threads.

[0008] Preferably, the rotating mechanism includes a third motor mounted on the frame, a main gear is provided below the frame, and the output shaft of the third motor is fixedly connected to the upper end of the main gear. A moving gear is connected to the outside of the hollow column, and the main gear meshes with the moving gear.

[0009] Preferably, a protruding ring is fixedly provided on the lower side of the connecting pipe, and an annular groove is provided on the inner side of the hollow column, with the protruding ring slidably embedded in the annular groove.

[0010] Preferably, a support platform is fixed to the inner side of the conveyor frame, and the two sides of the support platform are respectively attached to the inner side of the conveyor belt.

[0011] Preferably, a baffle is also fixed on one side of the printing plate.

[0012] The beneficial effects of this utility model are as follows: 1. The rotation of the first motor drives one of the rotating rollers to rotate, and then the other rotating roller enables conveyor belt transport. The moving mechanism drives two moving seats to move simultaneously, thereby adjusting the distance between the two moving seats. When the two moving seats move, they drive two connecting shafts to move simultaneously, thereby driving two guide frames to move simultaneously. Ultimately, the distance between the two guide frames can be adjusted. The staff can adjust the distance between the two guide frames according to the width of the packaging boxes to be printed in the same batch. Since the front ends of both guide frames are inclined, the packaging boxes can be guided back to their original positions through the front ends of the guide frames, so that the packaging boxes can pass straight between the two guide frames, which can play a role in limiting the transport of the packaging boxes, thereby ensuring the uniformity of the printing position of the packaging boxes in the same batch.

[0013] 2. The first electric push rod can drive the frame to move up and down, thereby driving the hollow column to move up and down, and finally driving the turntable to move up and down. Therefore, the height of the turntable can be adjusted according to the height of the packaging boxes in the same batch, so that the bristles can contact the upper surface of the packaging box. The rotating mechanism can drive the hollow column to rotate, thereby driving the turntable to rotate, and finally driving several bristles to rotate. The bristles are soft, so the surface of the packaging box can be cleaned by the bristles to ensure the cleanliness of the printed surface and further improve the printing quality.

[0014] 3. An airflow can be generated by a blower and delivered to a connecting pipe through a hose. Finally, the airflow is sent into the cavity inside the turntable through a hollow column and blown out through several air holes. This allows the airflow to be blown onto the surface of the packaging box while the brushes clean the box, further improving the cleaning efficiency and greatly increasing the practicality of the device.

[0015] 4. The output shaft of the second electric push rod can drive the printing plate to move up and down. When the packaging box passes under the printing plate, the printing plate can contact the upper surface of the packaging box to complete the printing work. The baffle can block one side of the packaging box to ensure that the printing plate can effectively contact the surface of the packaging box. Attached Figure Description

[0022] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0023] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0024] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figures 1 to 5 As shown, a packaging box printing device with a positioning mechanism includes a conveyor frame 1, and a conveying mechanism 2 is provided inside the conveyor frame 1. The conveying mechanism 2 can convey packaging boxes. The conveying mechanism 2 includes a first motor 21 installed on one side of the conveyor frame 1. Two rotating rollers 22 are installed inside the conveyor frame 1. The output shaft of the first motor 21 is fixedly connected to one end of one of the rotating rollers 22 through a coupling. A conveyor belt 23 is sleeved between the two rotating rollers 22. The rotation of the first motor 21 can drive one of the rotating rollers 22 to rotate, and then the other rotating roller 22 can be used to convey the packaging box through the conveyor belt 23. The coupling (not shown in the figure) can ensure the tension of the conveyor belt 23 to prevent the conveyor belt 23 from slipping. Therefore, the operator can place the packaging box to be printed on the upper end of the conveyor belt 23, and the packaging box is conveyed by the transmission of the conveyor belt 23.

[0025] Two guide frames 3 are symmetrically arranged on the inner side of the conveyor frame 1, with their front ends inclined. Connecting shafts 4 are threaded through both sides of the conveyor frame 1. One end of each connecting shaft 4 is fixedly connected to one side of each guide frame 3, and the other end is connected to a movable seat 5. A moving mechanism 6 is provided on the conveyor frame 1, and the moving mechanism 6 is connected to both movable seats 5. The moving mechanism 6 can drive the two movable seats 5 to move simultaneously, thereby adjusting the distance between them. When the two movable seats 5 approach each other, they can drive the two connecting shafts 4 to move simultaneously, thus driving the two guide frames 3 to move. When the two guide frames 3 move simultaneously, they move closer together. Conversely, when the two moving seats 5 move away from each other, the two guide frames 3 move further apart. This allows for adjustment of the distance between the two guide frames 3. The staff can adjust the distance between the two guide frames 3 according to the width of the packaging boxes to be printed in the same batch. Since the front ends of both guide frames 3 are inclined, the packaging boxes can be guided back to their original positions through the front ends of the guide frames 3. This allows the packaging boxes to pass straight between the two guide frames 3, which helps to limit the conveying of the packaging boxes and ensures the uniformity of the printing position of the packaging boxes in the same batch.

[0026] The moving mechanism 6 includes a rotating shaft 24. Mounting brackets 25 are fixedly mounted on both sides of the conveyor frame 1. Through slots 26 are opened on both sides of the conveyor frame 1. Two through slots 26 are passed through each end of the rotating shaft 24, and both ends are rotatably connected to the two mounting brackets 25. A second motor 27 is mounted on one side of each mounting bracket 25, and the output shaft of the second motor 27 is fixedly connected to one end of the rotating shaft 24. Rotation of the second motor 27 drives the rotating shaft 24 to rotate. Two external threads 28 with opposite directions are provided on the rotating shaft 24. Threaded holes are opened on the lower sides of the two moving seats 5, and the external threads 28 pass through the rotating shaft 24. Rotation of the rotating shaft 24 drives the two external threads 28 to rotate simultaneously. Since the two external threads 28 have opposite directions, the two moving seats 5 can be moved closer or further apart through the threaded holes, ultimately allowing adjustment of the distance between the two moving seats 5.

[0027] A frame 7 is fixedly installed at the upper end of the conveyor frame 1. A first electric push rod 8 is installed on the top of the frame 7. A frame body 9 is provided on the inner side of the frame 7. The output shaft of the first electric push rod 8 is fixedly connected to the upper end of the frame body 9. A hollow column 10 is rotatably connected to the lower end of the frame body 9. A turntable 11 is connected to the lower end of the hollow column 10. Several bristles 12 are connected to the lower end of the turntable 11. The frame body 9 can be moved up and down by the first electric push rod 8, which in turn moves the hollow column 10 up and down, and finally moves the turntable 11 up and down. Therefore, the height of the turntable 11 can be adjusted according to the height of the packaging boxes in the same batch so that the bristles 12 can contact the upper surface of the packaging box. A rotating mechanism 18 is provided on the frame 9, and the rotating mechanism 18 is connected to the hollow column 10. The rotating mechanism 18 can drive the hollow column 10 to rotate, thereby driving the turntable 11 to rotate, and finally driving several bristles 12 to rotate. The bristles 12 are soft bristles, so the surface of the packaging box can be cleaned by the bristles 12 to ensure the cleanliness of the printed surface and further improve the printing quality.

[0028] The rotating mechanism 18 includes a third motor 29 mounted on the frame 9. A main gear 30 is provided below the frame 9, and the output shaft of the third motor 29 is fixedly connected to the upper end of the main gear 30. A moving gear 31 is connected to the outside of the hollow column 10, and the main gear 30 meshes with the moving gear 31. The rotation of the third motor 29 can drive the main gear 30 to rotate, thereby driving the moving gear 31 to rotate, and finally driving the hollow column 10 to rotate, so as to drive the turntable 11 to rotate.

[0029] The turntable 11 has a cavity 13, and the hollow column 10 is connected to the cavity 13. Several air holes 14 are opened at the lower end of the turntable 11, all of which are connected to the cavity 13. A blower 15 is installed at the top of the frame 7. A connecting pipe 16 is rotatably connected to the upper end of the hollow column 10, and a flexible hose 17 connects the connecting pipe 16 and the blower 15. The blower 15 generates airflow, which is then transported through the flexible hose 17 to the connecting pipe 16. Finally, the airflow is delivered through the hollow column 10 into the cavity 13 within the turntable 11 and blown out through the air holes 14. This allows for airflow to be blown onto the surface of the packaging box while the brush 12 cleans it, further improving cleaning efficiency and greatly increasing the practicality of the device. In actual use, an electrostatic precipitator (not shown in the figure, representing existing technology) can also be installed inside the frame 7 to adsorb floating dust and prevent dust from flying away.

[0030] A protruding ring 32 is fixedly provided on the lower side of the connecting pipe 16, and an annular groove 33 is provided on the inner side of the hollow column 10. The protruding ring 32 is slidably embedded in the annular groove 33. When the hollow column 10 rotates, the protruding ring 32 can slide in the annular groove 33. Therefore, the cooperation between the protruding ring 32 and the annular groove 33 can play a role in limiting the installation of the connecting pipe 16 and the hollow column 10.

[0031] A second electric push rod 19 is also installed on the top of the frame 7. A printing plate 20 is provided on the inner side of the frame 7, and the output shaft of the second electric push rod 19 is fixedly connected to the upper end of the printing plate 20. The output shaft of the second electric push rod 19 can drive the printing plate 20 to move up and down. When the packaging box passes under the printing plate 20, the printing plate 20 can contact the upper surface of the packaging box to complete the printing work. The structure and model of the printing plate 20 are existing technologies, so they will not be described in detail. A baffle 35 is also fixed on one side of the printing plate 20. When the printing plate 20 moves downward, it can drive the baffle 35 to move downward. Therefore, the baffle 35 can block one side of the packaging box to ensure that the printing plate 20 can effectively contact the surface of the packaging box.

[0032] The inner side of the conveyor frame 1 is also fixed with a support platform 34, and the two sides of the support platform 34 are respectively attached to the inner side of the conveyor belt 23. The support platform 34 can provide a certain support for the packaging box on the conveyor belt 23 to prevent the support platform 34 from sinking.

[0033] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
