Description

Technical Field

[0001] This utility model relates to the field of reflective sheet feeding technology, specifically to an automatic feeding system for reflective sheet printing with correctable deviation. Background Technology

[0002] The automatic feeding system with corrective deviation for reflective sheet printing is mainly used in reflective sheet printing production. It can automatically complete the feeding of reflective sheets, improve production efficiency, and reduce manual operation. In the reflective sheet printing production process, the stability and accuracy of the feeding process play a decisive role in the final product quality. Traditional feeding methods mostly use sliding rails combined with top-loading cylinders, that is, the reciprocating motion of the top-loading cylinder pushes the reflective sheet placed on the sliding rail to the printing station. However, the top-loading cylinder, as a power output device, generates a large amount of kinetic energy during operation. In stark contrast, the reflective sheet is usually lightweight and thin. When the top-loading cylinder with its large kinetic energy acts on the lightweight reflective sheet, it is very easy for the reflective sheet to wobble during the pushing process. This wobble makes it difficult for the reflective sheet to reach the predetermined printing station stably and accurately, resulting in positional deviation. Once the reflective sheet is misaligned during loading, subsequent printing processes will not be able to guarantee that the pattern is accurately printed on the target area of ​​the reflective sheet, leading to a significant increase in the printing scrap rate. In view of this, we propose an automatic loading system for reflective sheet printing with corrective deviation. Utility Model Content

When the top-loading cylinder acts on the reflective sheet, it is easy for the sheet to sway during pushing, making it difficult to accurately reach the printing station and causing positional deviation. Once the feeding position is deviated, the subsequent printing process cannot guarantee that the pattern is accurately printed in the target area, resulting in a significant increase in the scrap rate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] The problem is that the top-loading cylinder, as a power output device, has a large kinetic energy when working, while the reflective sheet is small in mass and thin in material. When the top-loading cylinder acts on the reflective sheet, it is easy for the sheet to sway during the pushing process, making it difficult to accurately reach the printing station and causing positional deviation. Once the feeding position is deviated, the subsequent printing process cannot guarantee that the pattern is accurately printed in the target area, resulting in a significant increase in the scrap rate. like Figures 1-7 As shown, this embodiment provides an automatic feeding system for printing reflective sheets with corrective properties, including a support rail 1. An anti-deviation bearing assembly 2 is slidably connected to the upper surface of the support rail 1, and a docking mechanism 3 is slidably connected to one side of the support rail 1. The anti-deviation bearing assembly 2 includes a bearing platform 21, with two bearing seats 22 fixedly connected to the upper surface of the bearing platform 21. A bearing rod 23 is fixedly connected between the two bearing seats 22. A connecting seat 24 is slidably connected to the outer side of the bearing rod 23. Both ends of the connecting seat 24 are fixedly connected to buffer springs 25, which are sleeved on the outside of the bearing rod 23. A correction platform 26 is fixedly connected to the top of the connecting seat 24, and a correction rod 27 is elastically connected to the center of the correction platform 26. The front end of the correction rod 27 is fixedly connected to... The top of the correction rod 27 is fixedly connected to the limit mechanism 29, which is connected to the S pole magnetic block 28. The docking mechanism 3 includes a docking plate 31. A docking disk 32 is fixedly connected to the top of the docking plate 31 near the anti-deviation bearing component 2. An N pole magnetic block 33 is fixedly connected to the inner side of the docking disk 32. The height of the docking disk 32 is the same as the height of the correction rod 27. The N pole magnetic block 33 and the S pole magnetic block 28 are magnetically attracted to each other. Slide rails 8 are fixedly connected to both sides of the upper surface of the bearing platform 21. The two slide rails 8 are symmetrically arranged with the connecting seat 24 as the center. The top of the slide rail 8 is slidably connected to the lower surface of the correction platform 26. A top material cylinder 10 is fixedly connected to one end of the support rail 1. The telescopic end of the top material cylinder 10 is fixedly connected to the center of the bottom of the bearing platform 21. The buffer springs 25 at both ends of the connecting seat 24 can effectively cope with the inertial force generated when the correction table 26 moves. When the top material cylinder 10 pushes the correction table 26 to move quickly, the inertia of the correction table 26 will cause the connecting seat 24 to move on the bearing rod 23. At this time, the buffer springs 25 frequently extend and retract to offset or weaken this inertial force, avoid the reflector from being deviated due to shaking, and ensure that the reflector remains stable during the movement. The docking mechanism 3 also has a fine adjustment function for the position of the correction table 26. Through magnetic adsorption, the position of the correction table 26 can be precisely adjusted, which further improves the accuracy of feeding, reduces printing deviation, and thus ensures printing quality. like Figure 1-7 As shown, the limiting mechanism 29 includes a limiting rod 291, which is L-shaped. A fixed plate 292 is fixedly connected to the front end of the limiting rod 291, and a spring telescopic rod 293 is fixedly connected to the bottom end of the fixed plate 292. The telescopic end of the spring telescopic rod 293 is hinged to a limiting wheel 294 via a connecting seat. Heat dissipation grooves 295 are provided on both sides of the limiting rod 291. This design of the spring telescopic rod 293 and the limiting wheel 294 allows the limiting height to be automatically adjusted according to the thickness of the reflector. This improves the applicability to reflective sheets of different specifications. The "L"-shaped structure of the limiting rod 291, together with the fixed plate 292, the spring telescopic rod 293 and the limiting wheel 294, can accurately limit the position of the reflective sheet in the placement groove 6, prevent it from shifting during the printing process, and ensure printing accuracy. The heat dissipation groove 295 can assist in heat dissipation during its frequent movement, avoid the impact of frictional heat on the performance of the mechanism, and effectively extend the service life of the limiting mechanism 29 and reduce the occurrence of failures caused by overheating. like Figures 1-5 As shown, one side of the bottom of the docking plate 31 is slidably connected to one side of the support rail 1. The docking plate 31 and the correction table 26 are parallel to each other. There is a gap between the outer side of the docking plate 31 and the outer side of the correction table 26. There are multiple N-pole magnetic blocks 33 arranged inside the docking plate 32. The multiple N-pole magnetic blocks 33 are arranged equidistantly in a circle around the docking plate 32. An electromagnet 34 is fixedly connected to the bottom of the docking plate 31. The front end of the electromagnet 34 is magnetically attracted to the outer side of the support rail 1. This sliding connection design between the docking plate 31 and the support rail 1 makes it convenient to flexibly adjust the docking position and can adapt to the position requirements of different printing presses. Compared with the traditional mechanical fixing method, the adsorption fixing method of the electromagnet 34 is simpler and faster to operate, and the fixing effect is stable and reliable. The multiple equidistant N-pole magnetic blocks 33 enhance the adsorption force on the correction rod 27, which can quickly stop the shaking correction table 26 and improve the stability of feeding. In addition, the fine adjustment function of the docking mechanism 3 on the position of the correction table 26 further improves the accuracy of feeding and reduces printing deviation. like Figures 1-4As shown, the correction rod 27 is a three-section cylinder, which increases the heat dissipation area on the inner side of the correction rod 27 and reduces its weight. The correction table 26 has an internal movable groove 4. The inner side of the movable groove 4 is slidably connected to the outer side of the correction rod 27. The rear end of the correction rod 27 is fixedly connected to a return spring 9. The rear end of the return spring 9 is fixedly connected to one end of the inner wall of the movable groove 4. The setting of the return spring 9 can realize the automatic reset of the correction rod 27 and the limiting mechanism 29, reduce manual intervention, and improve work efficiency. like Figures 1-6 As shown, a vertically penetrating positioning groove 5 is provided on one side of the interior of the alignment table 26. The interior of the positioning groove 5 is connected to the interior of the movable groove 4. The inner wall of the positioning groove 5 slides in cooperation with the outer wall of the limiting rod 291. A placement groove 6 is provided at the center of the top of the alignment table 26. A limiting member 7 is fixedly connected to one side of the placement groove 6. The vertical cross-section of the limiting member 7 is "L" shaped. The limiting wheel 294 is located above the other side of the placement groove 6. The cooperation between the placement groove 6, the limiting member 7, and the limiting wheel 294 provides a stable placement and limiting environment for the reflective sheet, preventing the reflective sheet from shifting or falling before printing, improving the reliability of the feeding, and thus ensuring the printing quality.

[0017] In summary, the working principle of this solution is as follows: Before operation, the docking plate 31 is moved according to the position of the printing end of the printing machine. The support rail 1 serves as the moving path of the docking plate 31, ensuring precise alignment between the docking plate 31 and the printing end of the printing machine. This step ensures accurate material loading and prepares for subsequent material loading and printing. The electromagnet 34 is used to attract and firmly fix the contact point with the side of the support rail 1. The electromagnet 34 generates magnetism when energized, achieving reliable positioning of the docking plate 31 and preventing displacement of the docking mechanism 3 during subsequent material loading. This pushes the limiting mechanism 29 forward, placing the plate to be printed... The reflective sheet material is placed in a specific placement slot 6, and the limiting mechanism 29 is released. The limiting mechanism 29 is reset by the correction rod 27 under the pull of the return spring 9. The limiting member 7 is responsible for limiting the upper part of one side of the reflective sheet, and the limiting wheel 294 in the limiting mechanism 29 is responsible for limiting the upper part of the other side of the reflective sheet. During the feeding stage, the top material cylinder 10 is activated. The telescopic end of the top material cylinder 10 pushes the correction table 26 forward to the preset position. During the rapid movement of the correction table 26, the connecting seat 24 is fixedly connected to the correction table 26. The force generated by the inertia of the correction table 26 will be applied to the connecting seat. 24. This causes the connecting seat 24 to move. The bearing rod 23 provides a path for the movement of the connecting seat 24. The connecting seat 24 also compresses the buffer springs 25 at both ends. The buffer springs 25 use frequent expansion and contraction to counteract or weaken the force caused by the inertia of movement, so that the correction table 26 and the reflective sheet to be printed above remain stable. After the correction table 26 moves to the position of the docking mechanism 3, the magnetic force of the N pole magnetic block 33 quickly attracts the S pole magnetic block 28 at the front end, causing the correction rod 27 to move forward and fit tightly against the docking plate 32. This allows the shaking correction table 26 to stop quickly. Since the correction rod 27 is connected to the correction table 26... Meanwhile, the docking mechanism 3 can fine-tune the position of the correction table 26. After the correction adjustment, the position of the correction table 26 is more accurate. It should be added that the correction rod 27 will drive the limiting mechanism 29 to move quickly during the movement. The limiting rod 291 can move the limiting wheel 294 above the reflector through the spring telescopic rod 293. This will not obstruct the printing operation of the printing machine and improve the printing space. After the printing operation is completed, the reset spring 9 drives the anti-deviation bearing component 2 to reset. The correction rod 27 and the limiting mechanism 29 are also reset under the action of the reset spring 9 to prepare for the next printing operation.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
