Description

Technical Field

[0001] This invention relates to the field of inkjet printing for charging piles, and particularly to a multi-directional inkjet printing device for the production of charging piles. Background Technology

[0002] Charging stations are charging devices that provide energy replenishment for electric vehicles. After production, charging stations need to be transported in packaging boxes. The product packaging needs to be printed with the production date, barcode, QR code, and serial number.

[0003] Chinese patent document CN110962468A discloses a coding device for charging pile production, including a fixed machine base. The top of the fixed machine base has a vertically arranged mounting groove. Horizontally arranged rotating rollers are connected to both ends of the inner walls of the two sides of the fixed machine base via bearings. A horizontally arranged transmission belt is fitted onto the outer circumference of the two rotating rollers. Horizontally arranged fixed bases are bolted to the middle of both sides of the fixed machine base. A vertically arranged worktable is bolted to the top of the two fixed bases. In this invention, horizontally arranged electric push rods are bolted between the fixed side plates. A guide wheel is installed on one side of the electric push rod. The position of the charging pile is determined by a controller through a grating installed on the inner wall of the top of the fixed frame. The position of the charging pile is adjusted by a processor and four electric push rods to ensure the charging pile is centered and that coding is performed smoothly.

[0004] However, in actual use, the device places the packaging box on the surface of the conveyor belt, and the conveyor belt transports the packaging box to the bottom of the inkjet printer for inkjet printing. Since the inkjet printing position is different for different packaging boxes, in the above application, the inkjet printer can only be adjusted in height in the vertical direction. It cannot print on other positions on the top of the packaging box, the side of the packaging box, or the bottom of the packaging box, which greatly reduces the applicability of the inkjet printing device in the above application to charging pile packaging boxes.

[0005] Therefore, in view of the above problems, there is a need to provide a multi-directional inkjet printing device for charging pile production. Summary of the Invention

[0006] The main objective of this invention is to provide a multi-directional inkjet printing device for charging pile production, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

A third cylinder is fixedly installed inside the translation bracket. A housing is fixedly installed on one side of the piston rod of the third cylinder. An inkjet printer is rotatably installed on the side of the housing away from the column via a rotating shaft. The inkjet printer prints codes on different positions of the charging pile packaging box through the second cylinder and the third cylinder.

[0011] A switch assembly is provided at one end of the lifting base and one end of the column. A trigger assembly is provided on the back of the translation bracket and on the side of the lifting base near the column. An adjustment assembly is provided inside the housing. When the second cylinder drives the translation bracket to the last end, the inkjet printer rotates clockwise with the cooperation of the switch assembly in the lifting base, the trigger assembly in the translation bracket, and the adjustment assembly to print code on the side of the charging pile packaging box. When the lifting base descends to the switch assembly in the column, the inkjet printer rotates clockwise again to print code on the bottom of the charging pile packaging box.

[0012] The inside of the roller conveyor has a coding groove, and the coding groove corresponds to the position of the coding device. After the coding device is adjusted to be below the roller conveyor, the coding device will print the code on the bottom of the charging pile packaging box through the coding groove.

[0013] Preferably, the centering component includes two side support plates, and each side support plate is provided with a mounting housing. The mounting housing is rotatably provided with a plurality of evenly distributed conveying wheels. Two first cylinders are symmetrically arranged on the side of the mounting housing near the side support plate, and the first cylinders are fixedly connected to the side support plate.

[0014] Preferably, a first guide rod is fixedly provided at the bottom of the back side of the housing, the first guide rod passing through the translation bracket and extending to the back side of the translation bracket.

[0015] Preferably, a plurality of limiting grooves are provided on one side of the lifting seat, and a sliding bar with the same number as the limiting grooves is fixedly provided on one side of the translation bracket, and the sliding bar and the limiting grooves cooperate with each other.

[0016] Preferably, the adjusting assembly includes a first gear and a second gear, the first gear meshing with the second gear, and the first gear being rotatably disposed inside the housing, the second gear being connected to the inkjet printer, a rack being slidably disposed inside the housing, the rack meshing with the top of the first gear, a take-up motor being fixedly disposed inside the housing at the end away from the first gear, the output shaft of the take-up motor being connected to a take-up reel, a connecting rope being wound around the outside of the take-up reel, the end of the connecting rope away from the take-up reel being connected to the rack, and two third springs being disposed between the side of the rack near the take-up reel and the inner wall of the housing.

[0017] Preferably, two second guide rods are fixedly disposed inside the housing, the bottom end of the rack is slidably sleeved on the outside of the two second guide rods, and the two third springs are respectively sleeved on the outside of the two second guide rods.

[0018] Preferably, the switch assembly includes a support rod, a first switch and a second switch are disposed on the top of the support rod, and two pressing blocks are slidably disposed on the top of the support rod, the two pressing blocks respectively corresponding to the first switch and the second switch, and a first spring is disposed between the first switch and the second switch and the pressing blocks;

[0019] Both the first switch and the second switch are electrically connected to the winding motor.

[0020] Preferably, the triggering component includes a first trigger block and a second trigger block, both of which are rotatably disposed inside the translation bracket. The ends of the first and second trigger blocks near the first switch are inclined, and the first and second trigger blocks are mirror images of each other. A second spring is disposed between the side of the first and second trigger blocks near the inclined surface and the translation bracket.

[0021] Preferably, a guide wheel is fixedly provided at one end of the housing near the inside of the winding reel, and the connecting rope is provided on the lower side of the guide wheel.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This invention places the charging pile packaging box on top of a roller conveyor frame, which then transports the box to below the inkjet printer. Driven by a lifting motor, the lifting seat lowers the inkjet printer closer to the charging pile packaging box. Subsequently, a second cylinder pushes the translation bracket, housing, and inkjet printer to the front. Then, a third cylinder pushes the housing and inkjet printer forward until the inkjet printer is moved to the desired inkjet printing position on the charging pile packaging box, thus enabling inkjet printing processing on the top of the charging pile packaging box.

[0024] 2. In this invention, the switch component, trigger component, and adjustment component work together. When the second cylinder is shortened to its shortest distance, the trigger component at one end of the translation bracket works with the switch component in the lifting seat and transmits the signal to the adjustment component. The inkjet printer rotates 90 degrees clockwise, and at this time, the inkjet printer can perform inkjet printing on the side of the charging pile packaging box.

[0025] 3. In this invention, the switching component, triggering component, and adjusting component work together to make the piston rods in the second and third cylinders at their shortest lengths, causing the lifting seat to descend until the triggering component on one side of the lifting seat works with the switching component in the column and transmits a signal to the adjusting component. The inkjet printer then rotates 90 degrees clockwise again, at which point the inkjet printer can print the bottom of the charging pile packaging box through the inkjet printing slot.

[0026] 4. This invention uses a centering component to center multiple identical charging pile packaging boxes, ensuring that the packaging boxes are all positioned under the inkjet printer. This facilitates subsequent inkjet printing operations on multiple identical charging pile packaging boxes and prevents the need for multiple adjustments to the inkjet printer when multiple packaging boxes are moved to the inkjet printer in a disordered manner.

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0042] like Figures 1-13 As shown, this embodiment discloses a multi-directional inkjet printing device for charging pile production, including a roller conveyor frame 1 and a column 2. A lead screw 4 is rotatably installed inside the column 2, and a lifting motor 5 is fixedly installed on the top of the column 2. The output shaft of the lifting motor 5 is connected to the lead screw 4, and a lifting seat 6 is threadedly connected to the outside of the lead screw 4. By operating the lifting motor 5, the height of the lifting seat 6 is adjusted, thereby enabling inkjet printing on charging pile packaging boxes of different specifications and sizes.

[0043] A centering component 3 is provided at one end of the top of the roller conveyor 1. This component is used to center the charging pile packaging boxes on the top of the roller conveyor 1. It centers multiple identical charging pile packaging boxes so that the charging pile packaging boxes are moved to the same position under the inkjet printer 11. This facilitates the subsequent inkjet printer 11 inkjet printing operation on multiple identical charging pile packaging boxes and prevents the inkjet printer 11 from needing to be adjusted multiple times when multiple charging pile packaging boxes are moved to the position under the inkjet printer 11 for inkjet printing.

[0044] A second cylinder 7 is fixedly installed at the bottom of the lifting seat 6. A translation bracket 8 is fixedly installed on one side of the piston rod of the second cylinder 7. A third cylinder 9 is fixedly installed inside the translation bracket 8. A housing 10 is fixedly installed on one side of the piston rod of the third cylinder 9. An inkjet printer 11 is rotatably installed on the side of the housing 10 away from the column 2 via a rotating shaft. The inkjet printer 11 prints codes on different positions of the charging pile packaging box through the second cylinder 7 and the third cylinder 9.

[0045] A switch assembly 16 is provided at one end of the lifting seat 6 and one end of the column 2. A trigger assembly 17 is provided on the back of the translation bracket 8 and on the side of the lifting seat 6 near the column 2. An adjustment assembly 18 is provided inside the housing 10. When the second cylinder 7 drives the translation bracket 8 to the last end, the inkjet printer 11 rotates 90 degrees clockwise with the cooperation of the switch assembly 16 in the lifting seat 6, the trigger assembly 17 in the translation bracket 8 and the adjustment assembly 18 to print a code on the side of the charging pile packaging box. When the lifting seat 6 descends to the switch assembly 16 in the column 2, the inkjet printer 11 rotates 90 degrees clockwise again to print a code on the bottom of the charging pile packaging box.

[0046] The inside of the roller conveyor 1 has a coding groove 15, and the coding groove 15 corresponds to the position of the coding machine 11. After the coding machine 11 is adjusted to be below the roller conveyor 1, the coding machine 11 will print the bottom of the charging pile packaging box through the coding groove 15.

[0047] Furthermore, such as Figure 2 As shown, the centering component 3 includes two side support plates 31. Each side support plate 31 has a mounting shell 32 on its opposite side. Several evenly distributed conveying wheels 33 are rotatably arranged inside the mounting shell 32. Two first cylinders 34 are symmetrically arranged on the side of the mounting shell 32 near the side support plate 31. The first cylinders 34 are fixedly connected to the side support plate 31. When the charging pile packaging box passes through the centering component 3, the first cylinders 34 drive the mounting shell 32 to move inward, so that the conveying wheels 33 contact the surface of the charging pile packaging box, thereby centering the charging pile packaging box.

[0048] like Figure 4 and Figure 6 As shown, a first guide rod 12 is fixedly installed at the bottom of the back of the housing 10. The first guide rod 12 passes through the translation bracket 8 and extends to the back of the translation bracket 8. Through the first guide rod 12, when the third cylinder 9 drives the housing 10 to move, the first guide rod 12 improves the stability of the housing 10 when it moves.

[0049] like Figure 12 and Figure 13As shown, a number of limiting slide grooves 13 are provided on one side of the lifting seat 6, and the same number of slide bars 14 as the limiting slide grooves 13 are fixedly provided on one side of the translation bracket 8. The slide bars 14 and the limiting slide grooves 13 cooperate with each other. Under the cooperation of the limiting slide grooves 13 and the slide bars 14, the stability of the translation bracket 8 when moving under the action of the second cylinder 7 is improved.

[0050] like Figure 8 and Figure 9 As shown, the adjustment assembly 18 includes a first gear 181 and a second gear 182. The first gear 181 meshes with the second gear 182, and the first gear 181 is rotatably disposed inside the housing 10. The second gear 182 is connected to the inkjet printer 11. A rack 183 is slidably disposed inside the housing 10, and the rack 183 meshes with the top of the first gear 181. A take-up motor 184 is fixedly disposed inside the housing 10 at the end away from the first gear 181. The output shaft of the take-up motor 184 is connected to a take-up reel 185. A connecting rope 186 is wound around the outside of the take-up reel 185. The end of the connecting rope 186 away from the take-up reel 185 is connected to the rack 183. The side of the rack 183 near the take-up reel 185 is connected to the inner wall of the housing 10. Two third springs 187 are installed between them. When the switch assembly 16 transmits a signal to the take-up motor 184, the take-up motor 184 drives the take-up reel 185 to perform forward unwinding and reverse winding. When the take-up reel 185 rotates forward to unwind, the third springs 187 exert a pushing force on the rack 183, and the rack 183 moves forward along the second guide rod 188. The first gear 181 rotates counterclockwise, and the second gear 182 drives the inkjet printer 11 to rotate clockwise. The angle of each rotation of the second gear 182 is 90 degrees. When the take-up reel 185 rotates in reverse to wind up, the connecting rope 186 shortens, thereby pulling the rack 183 to move backward and squeezing the third springs 187. The second gear 182 then drives the inkjet printer 11 to rotate counterclockwise.

[0051] Furthermore, two second guide rods 188 are fixedly installed inside the housing 10. The bottom end of the rack 183 is slidably sleeved on the outside of the two second guide rods 188. Two third springs 187 are respectively sleeved on the outside of the two second guide rods 188. Through the second guide rods 188, the rack 183 can slide stably along the second guide rods 188, so that the rack 183 can always mesh with the first gear 181.

[0052] Furthermore, a guide wheel 19 is fixedly provided at one end of the housing 10 near the inside of the winding reel 185, and the connecting rope 186 is provided on the lower side of the guide wheel 19. The friction between the connecting rope 186 and the housing 10 is reduced by the guide wheel 19.

[0053] Therefore, the specific implementation method of this embodiment is as follows: When in use, the charging pile packaging box is placed on top of the roller conveyor 1. By starting the roller conveyor 1, the charging pile packaging box is conveyed to the area below the inkjet printer 11. When the charging pile packaging box passes the centering component 3, the first cylinder 34 drives the mounting housing 32 to move inward, so that the conveyor wheel 33 contacts the surface of the charging pile packaging box and centers the charging pile packaging box. When the charging pile packaging box moves to the area below the inkjet printer 11, the lifting seat 6 drives the inkjet printer 11 to descend and approach the charging pile packaging box through the drive of the lifting motor 5. Then, the second cylinder 7 pushes the translation bracket 8, the housing 10 and the inkjet printer 11 to the front. Then, the third cylinder 9 pushes the housing 10 and the inkjet printer 11 forward until the inkjet printer 11 is moved to the position where the charging pile packaging box needs to be printed, so that the top of the charging pile packaging box can be printed.

[0054] When it is necessary to print the side of the charging pile packaging box, firstly, the piston rod in the third cylinder 9 is shortened to its minimum, and then the second cylinder 7 is shortened to its shortest distance to drive the translation bracket 8 to move to the rearmost position. At this time, the trigger component 17 at one end of the translation bracket 8 cooperates with the switch component 16 in the lifting seat 6 and transmits the signal to the winding motor 184. The winding motor 184 rotates forward to unwind the wire, the third spring 187 generates a thrust on the rack 183, and the rack 183 moves forward along the second guide rod 188. The first gear 181 rotates counterclockwise, and the second gear 182 drives the inkjet printer 11 to rotate 90 degrees clockwise. At this time, the inkjet printer 11 can print the side of the charging pile packaging box. Furthermore, according to the size of the charging pile packaging box, the front and rear positions of the inkjet printer 11 can be adjusted by the third cylinder 9 based on the position of the translation bracket 8 at the rearmost end, so that the side of the charging pile packaging box of different specifications and sizes can be printed.

[0055] When it is necessary to print the bottom of the charging pile packaging box, the piston rods in the second cylinder 7 and the third cylinder 9 are at their shortest positions. The lifting motor 5 is started, which drives the lifting seat 6 to descend until the trigger component 17 on one side of the lifting seat 6 and the switch component 16 in the column 2 cooperate with each other and transmit the signal to the winding motor 184. The winding motor 184 rotates forward again to release the wire. The rack 183 moves forward again under the action of the third spring 187. The second gear 182 drives the inkjet printer 11 to rotate 90 degrees clockwise again. At this time, the inkjet printer 11 can print the bottom of the charging pile packaging box through the inkjet printing slot 15. At the same time, the front and rear positions of the inkjet printer 11 in this state can be adjusted by the third cylinder 9. Example 2

[0056] This embodiment further improves upon Embodiment 1 on a multi-directional inkjet printing device for charging pile production.

[0057] Specifically, such as Figure 5 and Figure 7 As shown, the switch assembly 16 includes a support rod 161. A first switch 162 and a second switch 163 are provided on the top of the support rod 161. Two pressing blocks 164 are slidably provided on the top of the support rod 161. The two pressing blocks 164 correspond to the first switch 162 and the second switch 163 respectively. A first spring 165 is provided between the first switch 162 and the second switch 163 and the pressing blocks 164.

[0058] Both the first switch 162 and the second switch 163 are electrically connected to the winding motor 184;

[0059] Furthermore, the trigger assembly 17 includes a first trigger block 171 and a second trigger block 172. Both the first trigger block 171 and the second trigger block 172 are rotatably disposed inside the translation bracket 8. The ends of the first trigger block 171 and the second trigger block 172 near the first switch 162 are inclined and mirror images of each other. A second spring 173 is disposed between the side of the first trigger block 171 and the second trigger block 172 near the inclined surface and the translation bracket 8.

[0060] Therefore, the specific implementation of this embodiment is as follows: When printing the side of the charging pile packaging box, the piston rod in the second cylinder 7 is retracted to its shortest length. At this time, the first trigger block 171 at one end of the translation bracket 8 acts on the pressing block 164 above. The pressing block 164 is forced to compress the first spring 165. When the pressing block 164 touches the first switch 162, the first switch 162 transmits a signal to the winding motor 184, controlling the winding motor 184 to rotate forward. The spring force of the second spring 173 is less than that of the first spring 165. While the upper pressing block 164 is in contact with the lower pressing block 164, the second trigger block 172 also contacts the lower pressing block 164. However, due to the shapes of the first trigger block 171 and the second trigger block 172, during the process of the translation bracket 8 moving to the rear end, when the second trigger block 172 contacts the lower pressing block 164, the second trigger block 172 is subjected to force and rotates, squeezing the second spring 173 on one side of the second trigger block 172. This prevents the second trigger block 172 from triggering the second switch 163. As the piston rod in the second cylinder 7 extends, As the translation bracket 8 moves forward, the first trigger block 171 rotates under the action of the upper pressing block 164, thus preventing the first switch 162 from being triggered. The second trigger block 172 then acts on the lower pressing block 164, triggering the second switch 163. The second switch 163 transmits a signal to the take-up motor 184, causing it to reverse. With the piston rods in the second cylinder 7 and the third cylinder 9 at their shortest lengths, the inkjet printer 11 moves downwards to print on the bottom of the charging pile. Similarly, the first trigger block 171 in front of the lifting seat 6 is triggered... The first trigger block 171 in front of the lifting platform 6 will not trigger the first trigger block 162 in front of the lifting platform 6, while the second trigger block 172 in the rear will not trigger the second trigger block 163 in the rear. The first trigger block 162 will transmit a signal to the winding motor 184, causing the winding motor 184 to rotate forward. Correspondingly, when the lifting platform 6 rises from below, the first trigger block 171 in front of the lifting platform 6 will not trigger the first trigger block 162 in front of the lifting platform 6, while the second trigger block 172 in the rear will trigger the second trigger block 163 in the rear. The second trigger block 163 will transmit a signal to the winding motor 184, causing the winding motor 184 to rotate in reverse.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
