Abstract

This utility model discloses a guiding device for multi-nozzle oil painting printing, relating to the technical field of guiding devices. It includes a correction guiding mechanism, with a compensation mechanism and a limiting mechanism arranged on its inner side. By coordinating the compensation and limiting mechanisms, this utility model ensures that during the correction process, the compensation mechanism, through the linkage of the limiting collar and the compensation connecting plate, allows the correction roller to maintain contact with the printing fabric even when tilted, enhancing the friction between the correction roller and the printing fabric and preventing secondary deviation due to insufficient friction, thus improving the stability of the canvas transport. Through the design of the lifting block and auxiliary roller in the limiting mechanism, the height of the auxiliary roller can be automatically adjusted via a pull rope mechanism during the correction process, ensuring it remains in contact with the printing fabric at all times, achieving secondary correction and guiding functions, further enhancing the trajectory control capability of the canvas during the correction process.

Description

Technical Field

[0001] This utility model relates to the field of guiding device technology, specifically a guiding device for multi-nozzle oil painting printing. Background Technology

[0002] A multi-head inkjet printing guide device is a mechanical device used to precisely control the movement of multiple inkjet heads along a preset trajectory on the artwork. Its core lies in the collaborative work of a mechanical structure and an intelligent control system, ensuring that inkjet heads of different colors or functions can operate synchronously or in shifts along predetermined paths, achieving high-fidelity image reproduction. This device is typically equipped with an adjustable guide rail system to adapt to canvases of different sizes, and incorporates sensors to calibrate the position in real time, compensating for deviations caused by factors such as material deformation.

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] Existing multi-nozzle oil painting guiding devices use sensors to detect whether the canvas has deviated. When a deviation occurs, feedback is sent to the cylinders at both ends of the correction roller, causing the correction roller to tilt and thus guide the canvas. However, during use, due to the tilt of the correction roller, the tilted end of the correction roller cannot make contact with the canvas above it. This reduces the friction between the correction roller and the canvas, making it difficult to stably constrain the movement trajectory of the canvas and easily causing secondary deviation of the canvas during transmission.

[0005] Therefore, this solution provides a guiding device for multi-nozzle oil painting printing to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a guiding device for multi-nozzle oil painting printing, so as to solve the problem that insufficient friction between the correction roller and the canvas during correction in the prior art leads to unstable canvas movement trajectory.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A guiding device for multi-nozzle oil painting printing includes a correction guiding mechanism, with a compensation mechanism and a limiting mechanism disposed on the inner side of the correction guiding mechanism; the correction guiding mechanism includes a support frame, an offset sensor mounted on the support frame, and two symmetrical mounting plates, with a linkage roller rotatably connected above the support frame and a correction shaft disposed thereon; the compensation mechanism includes a compensation connecting plate and limiting collars at both ends of the compensation connecting plate; the limiting mechanism includes a limiting slide and a lifting block at one end of the limiting slide, with a platform mounted on one side of the lifting block, and an auxiliary roller rotatably connected above the platform.

[0009] Preferably, a cylinder is installed above the mounting plate, the output end of the cylinder is connected to a correction slider, the two ends of the correction shaft are rotatably connected above the correction slider, and correction rollers are movably connected to the periphery of the correction shaft. The limiting collar is penetrated by the correction slider and located at both ends of the correction rollers.

[0010] Preferably, the lower part of the limiting collar is fixedly connected to the compensation connecting plate by the connecting plate, and the lower part of both ends of the compensation connecting plate is fixedly connected to the pull ring, and the inner side of the limiting collar is embedded with the circumferentially distributed rollers.

[0011] Preferably, a rotating shaft runs through the middle of the compensation connecting plate, a compensation slider is fixedly connected to the bottom of the rotating shaft, a compensation groove is provided above the limiting slide, the compensation slider is slidably connected inside the compensation groove, a receiving plate is fixedly connected below the limiting slide, and support frames are connected to both ends of the receiving plate.

[0012] Preferably, a slot is provided above one end of the limiting slide, the lifting block is slidably connected to the inside of the slot, and a stop block is slidably connected inside the compensation slide, the stop block fitting the bottom of the lifting block.

[0013] Preferably, one end of the limiting slide is rotatably connected to two symmetrical guide rollers, and both sides of one end of the abutment are connected to telescopic pull ropes. The telescopic pull ropes pass through the periphery of the guide rollers, and the other end of the telescopic pull ropes is fixedly connected to a pull ring. The lifting block has two symmetrical mounting slots, and one side of the platform is threaded with a positioning bolt, which passes through the mounting slot.

[0014] Preferably, a printing cloth is provided above the support frame, the printing cloth passes below the linkage roller and above the correction roller, and passes inside the offset sensor.

[0015] The beneficial effects of this utility model are:

[0016] I. This utility model, by setting up a compensation mechanism and a limiting mechanism to work together, during the correction process, when the contact area between the edge of the correction roller and the printing cloth is reduced due to tilting, the compensation mechanism can maintain full contact with the printing cloth while the correction roller is tilted through the linkage of the limiting collar and the compensation connecting plate. This enhances the friction between the correction roller and the printing cloth, avoids the problem of secondary offset caused by insufficient friction, and improves the stability and correction accuracy of the canvas transmission.

[0017] Second, through the design of the lifting block and auxiliary roller in the limiting mechanism, the height of the auxiliary roller can be automatically adjusted by the rope mechanism during the correction process, so that it always keeps in contact with the printing cloth, realizing the secondary correction and guiding functions, further enhancing the trajectory control capability of the canvas during the correction process, and improving the overall printing quality.

[0018] Third, this utility model can flexibly adapt to printing cloths of different thicknesses and widths by adjusting the connection height between the positioning bolt and the lifting block, thus enhancing the versatility and practicality of the device and making it suitable for various printing scenarios.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] According to the appendix Figure 1 - Figure 5 As shown, this utility model provides a guide device for multi-nozzle oil painting printing, including a correction guide mechanism 1, and a compensation mechanism 3 and a limiting mechanism 4 are provided on the inner side of the correction guide mechanism 1.

[0033] The correction guide mechanism 1 includes a support frame 11, an offset sensor 13 mounted on the support frame 11, and two symmetrical mounting plates 14. A linkage roller 12 is rotatably connected to the top of the support frame 11, and a correction shaft 17 is provided.

[0034] The compensation mechanism 3 includes a compensation connecting plate 31 and limiting collars 33 at both ends of the compensation connecting plate 31;

[0035] The limiting mechanism 4 includes a limiting slide 41 and a lifting block 43 at one end of the limiting slide 41. A platform 44 is installed on one side of the lifting block 43, and an auxiliary roller 45 is rotatably connected above the platform 44.

[0036] The correction guide mechanism 1 is placed at the input port of the multi-head oil painting printing machine to guide the canvas into the printing machine; the offset sensor 13 can determine the position of the edge of the printing cloth 2 by laser irradiation, and the offset of the edge of the printing cloth 2 will be fed back to the controller, which will cause the cylinder 15 to operate for correction. If the printing cloth 2 is offset to the left during correction, the left cylinder 15 will extend its output end, while the right cylinder 15 will retract its output end, thereby causing the correction shaft 17 and the correction roller 18 to tilt on the horizontal plane, thereby correcting the offset printing cloth 2 to the correct track and guiding it.

[0037] In a further embodiment, a cylinder 15 is mounted above the mounting plate 14. The output end of the cylinder 15 is connected to a correction slider 16. The two ends of the correction shaft 17 are rotatably connected above the correction slider 16. A correction roller 18 is movably connected to the periphery of the correction shaft 17. The limiting collar 33 is penetrated by the correction slider 16 and located at both ends of the correction roller 18.

[0038] In this embodiment, the correction slider 16 is slidably connected above the mounting plate 14, and the sliding direction is consistent with the direction of the mounting plate 14; the correction roller 18 can be rotatably connected, and can also slide along the axial direction.

[0039] In a further embodiment, the lower part of the limiting collar 33 is fixedly connected to the compensation connecting plate 31 by the connecting plate 32, and the lower part of both ends of the compensation connecting plate 31 is fixedly connected to the pull ring 35. The inner side of the limiting collar 33 is embedded with the circumferentially distributed rollers 34.

[0040] In this embodiment, the inner side of the limiting collar 33, through which the correction shaft 17 passes, has a certain gap with the correction shaft 17 and is equipped with balls. The compensation connecting plate 31 is parallel to the correction shaft 17. The roller 34 is used to reduce friction with both ends of the correction roller 18. Therefore, the correction roller 18 is restricted by both the limiting collars 33 at both ends and by the compensation slider 37 and the compensation groove 411, thus compensation can be performed, so that the center of the compensation connecting plate 31 and the correction roller 18 after tilting and rotating is still within the range of the compensation groove 411.

[0041] In a further embodiment, a rotating shaft 36 passes through the middle of the compensation connecting plate 31, and a compensation slider 37 is fixedly connected to the bottom of the rotating shaft 36. A compensation groove 411 is provided above the limiting slide block 41, and the compensation slider 37 is slidably connected inside the compensation groove 411. A receiving plate 49 is fixedly connected below the limiting slide block 41, and support frames 11 are connected to both ends of the receiving plate 49.

[0042] In this embodiment, the rotating shaft 36 makes the correction shaft 17 and the correction roller 18 centered on the rotating shaft 36 when tilted; the receiving plate 49 is used to support the limiting slide 41 so that the limiting slide 41 is in the middle position at the bottom of the support frame 11 during installation.

[0043] In a further embodiment, a plug groove 412 is provided above one end of the limiting slide block 41, and the lifting block 43 is slidably connected to the inside of the plug groove 412. A stop block 47 is slidably connected inside the compensation slide groove 411, and the stop block 47 fits the bottom of the lifting block 43.

[0044] In this embodiment, the bottom of the lifting block 43 is provided with a notch so that it can fit into the abutment block 47; the abutment block 47 is composed of a long strip, a pull ring and an inclined abutment block, wherein the inclined abutment block fits into the notch at the bottom of the lifting block 43 so as to lift the lifting block 43.

[0045] In a further embodiment, one end of the limiting slide 41 is rotatably connected to two symmetrical guide rollers 42, and the two sides of one end of the abutment block 47 are connected to telescopic pull ropes 48. The telescopic pull ropes 48 pass through the periphery of the guide rollers 42, and the other end of the telescopic pull ropes 48 is fixedly connected to a pull ring 35. The lifting block 43 has two symmetrical mounting grooves 431, and one side of the base 44 is threaded with a positioning bolt 46, which passes through the mounting groove 431.

[0046] In this embodiment, the opening of the mounting groove 431 allows the height of the platform 44 to be selected when it is installed by the positioning bolt 46, thereby preventing the auxiliary roller 45 from exceeding the outer periphery of the correction roller 18. At the same time, the auxiliary roller 45 can also be adapted when facing different printing cloths 2 and when the correction roller 18 is replaced. The telescopic pull rope 48 has a certain elasticity, so it can extend and retract when one end is pulled by the pull ring 35.

[0047] In a further embodiment, a printing cloth 2 is disposed above the support frame 11, the printing cloth 2 passes below the linkage roller 12 and above the correction roller 18, and passes inside the offset sensor 13.

[0048] In this embodiment, the correction and guidance mechanism 1 constitutes a correction and guidance device, while the printing cloth 2 is the canvas to be printed.

[0049] The working principle of this utility model is as follows:

[0050] When the printing cloth 2 deviates, the deviation sensor 13 can provide feedback to the external control device, which can then operate the cylinders 15 at both ends to tilt the two ends of the correction shaft 17, along with the correction rollers 18, in the direction of deviation, thereby correcting the deviation. During this process, since the compensation connecting plate 31 is rotatably connected above the compensation slider 37 via the rotating shaft 36, and the compensation slider 37 is slidably connected in the compensation groove 411 of the limit slide 41, when the correction shaft 17 rotates, it will cause the limit collar 33, the connecting plate 32, and the compensation connecting plate 31 to rotate around the rotating shaft 36. Thus, the correction shaft 17 can be finely adjusted through the limit collar 33, so that the two ends and the middle of the correction shaft 17 still maintain contact with the printing cloth 2 when tilted, thereby preventing deviation.

[0051] Additionally, when the correction shaft 17 and correction roller 18 tilt, causing the compensation connecting plate 31 to tilt, the lower ends of the compensation connecting plate 31 can pull the telescopic rope 48 through the pull ring 35, thereby causing the stop block 47 to contact the lower part of the lifting block 43. This allows the lifting block 43 to move upward along with the platform 44 and the auxiliary roller 45, so that the top of the auxiliary roller 45 can contact the printing cloth 2, thereby providing auxiliary secondary correction guidance. At the same time, the initial height of the platform 44 and the auxiliary roller 45 can be adjusted according to the thickness of the correction roller 18 by rotating the positioning bolt 46 to adjust the connection height with the lifting block 43, thus adapting to printing cloths 2 of different widths.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
