[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] The present invention is described in further detail below with reference to the accompanying drawings:

[0038] like Figures 1 to 5 As shown, a rotary inkjet printer device for a cylindrical support carrier according to the present invention includes: a fixed plate 1 and an inkjet printer 2 mounted on the fixed plate 1, a guide plate assembly 3, a lifting and pressing assembly 5, a power roller assembly 4 and a push plate assembly 6;

[0039] The guide plate assembly 3 includes a guide plate 31, which is provided with an arc-shaped guide groove 32. The coding device 2 is fixed to the position above the fixed plate 1 corresponding to the arc-shaped guide groove 32. The cylindrical support carrier 7 to be coded is placed on the arc-shaped guide groove 32 and the coding device 2 is sleeved in the cylindrical structure.

[0040] The power roller assembly 4 includes a driving assembly and a rubber-coated roller 43. The rubber-coated roller 43 is installed above the corresponding inkjet printer 2. The driving assembly can drive the rubber-coated roller 43 to rotate through the transmission assembly 42.

[0041] The jacking and pressing assembly 5 is arranged below the guide plate 31. The jacking and pressing assembly 5 includes a jacking cylinder 51 and a pressing roller assembly. Driven by the jacking cylinder 51, the pressing roller assembly can pass upward through the arc guide groove 32 and jack up the cylindrical support carrier 7 to pre-press it with the rubber coating roller 43, and drive the cylindrical support carrier 7 to rotate synchronously under the rotation of the rubber coating roller 43. At the same time, the coding device 2 is used to code the cylindrical inner wall of the cylindrical support carrier 7; the coding device 2 does not contact the cylindrical support carrier 7.

[0042] The push plate assembly 6 includes a push plate cylinder 61 and a push plate 62 . Driven by the push plate cylinder 61 , the push plate 62 can push the cylindrical support carrier 7 to slide along the arc-shaped guide groove 32 until it is out of the arc-shaped guide groove 32 .

[0043] In this embodiment, through the coordinated cooperation of the guide plate 31, the jacking and clamping assembly 5 and the power roller assembly 4, the cylindrical support carrier 7 placed on the guide plate 31 can automatically reach the coding position of the coding equipment 2. The process action is simple and the logic is clear and clear, which can effectively shorten the coding time and greatly improve the production efficiency. It can also realize the rotation of the cylindrical support carrier 7 to cooperate with the coding process of the coding equipment 2, and realize a larger area spraying on the cylindrical structure, thereby realizing complex identification coding, and the fixed plate 1 can carry a preset number of groups of coding equipment 2 to realize multi-piece coding at the same time, thereby improving the scalability and production efficiency of the rotary coding device.

[0044] Specifically, before inkjet printing, the cylindrical support carrier 7 to be coded is placed in the arc-shaped guide groove 32 of the guide plate 31. By moving the guide plate 31 back and forth, the cylindrical support carrier 7 can be moved to the coding position of the inkjet device 2. Through the lifting action of the lifting and pressing assembly 5, the pressing roller assembly passes through the slot in the arc-shaped guide groove 32 from bottom to top, and lifts the cylindrical support carrier 7 so that its upper surface is pre-pressed against the surface of the rubber-coated roller 43 above the inkjet device 2. At this time, the power roller assembly 4 drives its rubber-coated roller 43 to rotate. The friction between the rubber-coated roller 43 and the cylindrical support carrier 7 enables the cylindrical support carrier 7 to rotate synchronously with the rubber-coated roller 43. During the rotation, the pressing roller assembly can rotate synchronously to provide stable support for the cylindrical support carrier 7.

[0045] During this process, the preset rubber-coated roller 43 drives the rotation speed and direction of the cylindrical support carrier 7 to adapt it to the coding process of the coding device 2, so that while the coding device 2 is coding, the cylindrical support carrier 7 rotates in a preset direction at a certain speed, so that the logo or pattern sprayed on the inner wall of the cylindrical structure adapts to the shape and specifications of the cylindrical support carrier 7, thereby realizing the coding of complex logos, such as barcodes, QR codes, trademark logos, etc.

[0046] After the coding is completed, the cylindrical support carrier 7 is pushed out along the arc guide groove 32 by the push plate assembly 6, and then the spraying process of the new cylindrical support carrier 7 is carried out, realizing full-process automated operation and improving production efficiency.

[0047] In the above embodiment, preferably, a preset number of groups of inkjet printer devices 2 are installed on the fixed plate 1, and the guide plate 31 is provided with arc guide grooves 32 corresponding to the number of inkjet printer devices 2, the power roller assembly 4 includes a corresponding number of rubber-coated rollers 43 corresponding to the number of inkjet printer devices 2, and the jacking and compacting assembly 5 includes a corresponding number of compacting roller assemblies corresponding to the number of inkjet printer devices 2.

[0048] In this embodiment, by expanding the coding device 2, synchronous coding of multiple groups of cylindrical support carriers 7 can be achieved at the same time. The number of coding devices 2 is set according to the implementation scenario and requirements, and 3 to 5 groups are preferably used.

[0049] like Figure 6 As shown, in the above embodiment, preferably, the guide plate assembly 3 also includes a guide cylinder 33, the guide cylinder 33 is fixed relative to the fixed plate 1 through a connecting angle plate 34, the plate surface of the guide plate 31 is vertically arranged relative to the plate surface of the fixed plate 1, and the guide plate 31 is connected to the movable end of the guide cylinder 33 through a cylinder connecting plate 35, and can be moved back and forth relative to the inkjet printer 2 under the drive of the guide cylinder 33.

[0050] Specifically, the guide cylinders 33 are disposed on either side of the fixed plate 1 relative to the guide plate 31. The guide cylinders 33 are fixed relative to the fixed plate 1. The guide plate 31 is connected to the guide cylinders 33 via the cylinder connecting plates 35. During the extension and retraction of the movable end of the guide cylinders 33, the guide plate 31 can be driven to move forward and backward. The cylinder connecting plates 35 or the movable end of the guide cylinders 33 preferably extend through the fixed plate 1, allowing the guide plate 31 to have a more effective displacement distance relative to the inkjet printer 2.

[0051] like Figure 6As shown, in the above embodiment, preferably, linear guide rails 36 are further provided on both sides of the guide plate 31, and the linear guide rails 36 are movably connected to the slider 37. A connecting ear plate 38 is fixed on the slider 37, and the connecting ear plate 38 is fixed on the fixed plate 1, so that when the guide plate 31 is driven by the guide cylinder 33, the guide plate 31 can make a reciprocating linear motion relative to the slider 37 through the linear guide rails 36.

[0052] Furthermore, through the linear guide rails 36 set on both sides of the guide plate 31, the slider 37 is fixed relative to the fixed plate 1 through the connecting ear plate 38. In this way, when the guide cylinder 33 drives the guide plate 31 to move back and forth, it can obtain stable support from the linear guide rails 36, so that the guide plate 31 can achieve stable reciprocating linear motion.

[0053] Preferably, the guide plate 31 is integrally passed through the fixed plate 1, and both sides of the guide plate 31 are slidably mounted on the fixed plate 1 through linear guide rails 36, sliders 37 and connecting ear plates 38. The ends of the guide plate 31 are connected to the movable ends of the guide cylinders 33 through cylinder connecting plates 35. A buffer stop seat 39 is installed on the side of the guide plate 31 close to the guide cylinder 33 relative to the fixed plate 1. When the guide plate 31 moves toward the side of the inkjet printer 2 driven by the guide cylinder 33, the buffer stop seat 39 is used as a limiting device when it approaches the fixed plate 1 to prevent the guide plate 31 from rigidly colliding with the fixed plate 1 or exceeding the preset position.

[0054] like Figure 4 As shown, in the above embodiment, preferably, the driving assembly includes a driving device 41 and a transmission assembly 42. The driving device 41 is fixed relative to the fixed plate 1, and the rubber-coated roller 43 is vertically installed on the fixed plate 1 through the first linear bearing seat 44, and a clamping end cover 45 is provided at the axial end for limiting. The driving device 41 drives the rubber-coated roller 43 to rotate relative to the first linear bearing seat 44 through the transmission assembly 42, so as to drive the cylindrical support carrier 7 to rotate synchronously under the action of friction.

[0055] In this embodiment, the rubberized roller 43, the driving device 41, and the transmission assembly 42 are respectively arranged on both sides of the fixed plate 1. The rubberized roller 43 is mounted on the fixed plate 1 by a first linear bearing seat 44, so that the rubberized roller 43 can be driven by the transmission assembly 42 and rotate relative to the fixed plate 1 with the power of the driving device 41. During the rotation process, the first linear bearing seat 44 provides stable support for the rubberized roller 43, and the clamping end cap 45 provides a limit at the end to prevent the rubberized roller 43 from moving in the axial direction. Preferably, the surface of the rubberized roller 43 is made of rubber material, which can provide stable static friction for the cylindrical support carrier 7 when the cylindrical support carrier 7 is pre-pressed against the surface of the rubberized roller 43, thereby driving the cylindrical support carrier 7 to rotate without causing relative sliding.

[0056] like Figure 7 As shown, in the above embodiment, preferably, the driving device 41 includes a driving motor 411, a motor base 412 and a reducer 413. The driving motor 411 is mounted on the fixing plate 1 through the motor base 412, and the reducer 413 is cooperatively connected to the driving motor 411;

[0057] The transmission assembly 42 includes a synchronous wheel 421 and a synchronous belt 422. The synchronous wheel 421 is installed at the power output end of the reducer 413 and the power input end of the rubber-coated roller 43. The synchronous belt 422 is wound between the synchronous wheels 421 and drives the rubber-coated rollers 43 corresponding to all the inkjet printer devices 2 to rotate through the synchronous wheel 421 when the reducer 413 outputs power.

[0058] In this embodiment, the reducer 413 converts the output power of the drive motor 411 into the rotation speed required by the rubber-coated roller 43, and the synchronous belt 422 can synchronously transmit the output power of the reducer 413 to the synchronous wheel 421 corresponding to each rubber-coated roller 43, driving all the rubber-coated rollers 43 to rotate synchronously, thereby realizing the synchronous coding process of all cylindrical support carriers 7.

[0059] like Figure 5 As shown, further, a tensioning device 46 is fixed on the fixed plate 1 to tension the synchronous belt 422 between the synchronous wheels 421 to ensure that the synchronous wheels 421 rotate synchronously.

[0060] like Figure 8 As shown, in the above embodiment, preferably, the lifting and pressing assembly 5 further includes a guide shaft mounting plate 53, a cylinder mounting seat 54, a lifting guide shaft 55 and a compression spring 56, and the pressing roller assembly includes a roller mounting plate 57, a side support plate 58 and a pressing roller 52;

[0061] The cylinder mounting seat 54 is fixed on the fixed plate 1, and the lifting cylinder 51 is installed on the cylinder mounting seat 54; the lifting cylinder 51 drives the guide shaft mounting plate 53, and the plate surface of the guide shaft mounting plate 53 is vertically arranged relative to the plate surface of the fixed plate 1.

[0062] The lifting guide shaft 55 is vertically mounted on the guide shaft mounting plate 53 via a second linear bearing seat 59. A fixing ring 510 is mounted on the bottom end of the lifting guide shaft 55. The top end of the lifting guide shaft 55 passes through the guide shaft mounting plate 53 and is fixedly connected to the roller mounting plate 57. A compression spring 56 is mounted on the lifting guide shaft 55 and is located between the roller mounting plate 57 and the guide shaft mounting plate 53. Two sets of side support plates 58 are fixed on both sides of the top of the roller mounting plate 57. The two sets of compression rollers 52 are respectively mounted between the two sets of side support plates 58.

[0063] The movable end of the lifting cylinder 51 is connected to the guide shaft mounting plate 53. The guide shaft mounting plate 53 moves upward under the lifting action of the lifting cylinder 51, driving the two sets of clamping rollers 52 to pass through the slots of the arc-shaped guide groove 32 to support the cylindrical support carrier 7, and pre-tighten the cylindrical support carrier 7 onto the rubber-coated roller 43 under the elastic force of the compression spring 56.

[0064] In this embodiment, the jacking and pressing assembly 5 is installed as a whole below the guide plate assembly 3, and the two groups of pressing rollers 52 of the pressing roller 52 assembly are symmetrically arranged relative to the cylindrical support carrier 7. Under the lifting action of the jacking cylinder 51 through the jacking guide shaft 55, the pressing roller 52 passes through the slot of the arc-shaped guide groove 32 and stably supports the cylindrical support carrier 7, so that the cylindrical support carrier 7 can be pre-pressed to the surface of the rubber-coated roller 43.

[0065] Among them, the arrangement of the second linear bearing seat 59 and the jacking guide shaft 55 relative to the guide shaft mounting plate 53 can ensure that the clamping roller 52 assembly can achieve stable up and down linear reciprocating motion under the jacking action of the jacking cylinder 51.

[0066] The compression spring 56 provides a buffer when the compression roller 52 presses the cylindrical support carrier 7 upward onto the surface of the rubber-coated roller 43, achieving effective compression while preventing damage to the cylindrical support carrier 7 caused by hard contact. Specifically, the pre-compression force of the compression spring 56 can be adjusted by adjusting the position of the fixing ring 510 at the bottom of the lifting guide shaft 55.

[0067] like Figure 9 As shown, in the above embodiment, preferably, the push plate assembly 6 also includes a push plate guide shaft 63, which is vertically mounted on the fixed plate 1 through a third linear bearing seat, and the push plate 62 is fixed to one end of the push plate guide shaft 63. The push plate cylinder 61 is fixed on the fixed plate 1, and the movable end of the push plate cylinder 61 passes through the fixed plate 1 and is connected to the push plate 62. The push plate cylinder 61 can drive the push plate 62 to move back and forth, and is guided by the reciprocating motion of the push plate guide shaft 63 relative to the third linear bearing seat, and when the push plate 62 moves forward, it can push the cylindrical support carrier 7 to slide along the arc guide groove 32.

[0068] In this embodiment, the push plate guide shaft 63 can be installed through the fixed plate 1 or can be installed astride the top of the fixed plate 1. The push plate 62 serves as the pushing component of the cylindrical support carrier 7. To prevent the inkjet printer 2 from blocking the push plate 62 during its pushing process, a groove is preferably formed on the push plate 62. The edge of the groove intersects with the end face of the cylindrical support carrier 7. During the pushing process, the cylindrical support carrier 7 is pushed through the intersection, and the inkjet printer 2 passes through the groove.

[0069] Among them, preferably, the push plate guide shafts 63 are symmetrically installed on both sides of the push plate 62, so that the push plate 62 can move stably and balanced under the pushing action of the push plate cylinder 61 without causing the push plate 62 to tilt relative to the inkjet device 2.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
