Description

Technical Field

[0001] This utility model relates to the field of steel plate transfer technology, and in particular to a steel plate centering and pushing mechanism. Background Technology

[0002] Gravure printing rollers are made by coating the entire surface of the roller with ink, then using a special doctor blade to remove the ink from the blank areas, leaving only the ink in the halftone dots of the image areas. Under the pressure generated during rolling, the ink is transferred to the surface of the substrate to obtain the printed product. Gravure printing rollers are a type of direct printing. The image areas of the gravure printing roller are recessed, and the degree of recess varies with the depth of the image. The blank areas of the printing plate are raised and on the same plane.

[0003] During the processing of gravure rollers, a flat steel plate is continuously rolled to form a roller-like structure. When entering the winding mechanism, the steel plate needs to be pushed into the winding mechanism by a pushing mechanism. Most existing pushing mechanisms use rolling support to advance into the winding mechanism, which will cause friction on the surface of the steel plate, resulting in more serious scratches. In addition, the steel plate has weight, and rolling support can also easily cause the steel plate to deform. Utility Model Content

[0004] The purpose of this invention is to provide a steel plate centering and pushing mechanism to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A steel plate centering and pushing mechanism includes a centering support plate for supporting the steel plate. The centering support plate is provided with a drive seat, which can move along the length direction of the centering support plate. The drive seat is provided with a clamping module and a positioning module. The clamping module includes a pair of spaced-apart clamping bars, with side clamping plates installed at the ends of the clamping bars and transversely arranged support plates installed on the side clamping plates. The positioning module includes a positioning plate located between the two clamping bars, with a positioning block installed at the end of the positioning plate that elastically contacts the side wall of the steel plate.

[0007] Furthermore: the drive seat is provided with an adjustment mechanism for adjusting the distance between the two clamping bars. The adjustment mechanism includes an adjustment screw arranged along the length of the drive seat. The left and right halves of the adjustment screw are respectively formed with external thread structures. The direction of the external thread structure of the left half is opposite to that of the external thread structure of the right half. An adjustment sliding seat is installed at the inner end of the clamping bar. The adjustment sliding seat is equipped with an adjustment sleeve that is threaded to the external thread structure.

[0008] Furthermore, the adjustment mechanism also includes adjustment guide rods disposed on both sides of the adjustment screw, and the adjustment sliding seat is equipped with an adjustment sleeve seat that slides in cooperation with the adjustment guide rods.

[0009] Furthermore: bearing seats are installed at both ends of the drive seat, and the adjusting screw is installed between the two bearing seats. The drive seat also has a drive motor and a reducer located on the outside of one of the bearing seats.

[0010] Furthermore: a longitudinally arranged motor plate is provided at one end of the drive base, and the drive motor and reducer are respectively mounted on the motor plate. The drive end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the adjusting screw.

[0011] Furthermore: there are two or more positioning plates, and the two positioning plates are arranged at intervals. Positioning posts are installed on the outer ends of the positioning plates. The positioning blocks are formed with sliding holes that slide with the positioning posts. A compression spring is provided between the positioning plates and the positioning blocks and sleeved on the positioning posts.

[0012] Furthermore: a bottom support plate is provided at the bottom of the central support plate, and a bottom drive mechanism is provided below the bottom support plate to drive the drive seat to move along the length direction of the central support plate.

[0013] Furthermore: Guide structures for sliding support drive seats are provided on both sides of the bottom support plate along the length direction.

[0016] The beneficial effects of this utility model are as follows: The steel plate to be wound is placed on the central support plate, and the steel plate is located between the two side clamping plates. Since the support plate provides lateral support, the lateral support plate can support the steel plate. Then, the distance between the two clamping strips is adjusted so that the side clamping plates contact the two side walls of the steel plate to achieve clamping.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1-3 As shown, a steel plate centering and pushing mechanism includes a centering support plate 1 for supporting the steel plate. The centering support plate 1 is provided with a drive seat 11, which can move along the length direction of the centering support plate 1. The drive seat 11 is provided with a clamping module 12 and a positioning module 2. The clamping module 12 includes a pair of spaced clamping bars 13, with side clamping plates 14 installed at the ends of the clamping bars 13 and transversely arranged support plates 15 installed on the side clamping plates 14. The positioning module 2 includes a positioning plate 21 located between the two clamping bars 13, with a positioning block 22 installed at the end of the positioning plate 21 that elastically contacts the side wall of the steel plate.

[0033] The steel plate to be wound is placed on the central support plate 1, with the steel plate positioned between the two side clamping plates 14. Due to the lateral support of the support plate 15, the lateral support plate can support the steel plate. Subsequently, the distance between the two clamping strips 13 is adjusted so that the side clamping plates 14 contact the two side walls of the steel plate, achieving clamping. In conjunction with the support plate 15, the steel plate can be clamped and supported without the need for rolling support. Then, the drive seat 11 moves along the length of the central support plate 1 to push the steel plate into the winding mechanism. When pushed in, the positioning block 22 installed on the positioning plate 21 makes elastic contact with the front side wall of the steel plate, which has a certain buffering effect and improves the winding quality.

[0034] Specifically, the drive base 11 is equipped with an adjustment mechanism 3 for adjusting the distance between the two clamping bars 13. The adjustment mechanism 3 includes an adjustment screw 31 arranged along the length of the drive base 11. The left and right halves of the adjustment screw 31 are respectively formed with external thread structures, and the direction of the external thread structure of the left half is opposite to that of the external thread structure of the right half. An adjustment sliding seat 16 is installed at the inner end of the clamping bar 13, and an adjustment sleeve 32 that is threadedly engaged with the external thread structure is installed on the adjustment sliding seat 16. When the adjustment screw 31 rotates, it simultaneously engages with the two adjustment sleeves 32. Since the direction of the external thread structure of the left half is opposite to that of the external thread structure of the right half, the two adjustment sleeves 32 will move closer or further apart to adjust the distance between the two clamping bars 13, which is convenient for adapting to steel plates of different sizes and for clamping and tightening the steel plates.

[0035] Furthermore, the adjusting mechanism 3 also includes adjusting guide rods 33 disposed on both sides of the adjusting screw 31, and the adjusting sliding seat 16 is equipped with an adjusting sleeve seat 34 that slides with the adjusting guide rods 33. When the adjusting sliding seat 16 moves along the length direction of the adjusting screw 31, the adjusting sleeve seat 34 slides with the adjusting guide rods 33 to ensure the stable movement of the adjusting sliding seat 16.

[0036] Furthermore, bearing seats 35 are respectively installed at both ends of the drive base 11, and an adjusting screw 31 is installed between the two bearing seats 35. The drive base 11 also has a drive motor 37 and a reducer 38 located on the outside of one of the bearing seats 35. A longitudinally arranged motor plate 36 is provided at one end of the drive base 11. The drive motor 37 and the reducer 38 are respectively installed on the motor plate 36. The drive end of the drive motor 37 is connected to the input end of the reducer 38, and the output end of the reducer 38 is connected to the adjusting screw 31. The drive motor 37 and the reducer 38 form a power output to drive the adjusting screw 31 installed on the bearing seat 35 to rotate, thereby adjusting the distance between the two clamping bars 13, which is convenient for adapting to steel plates of different sizes and for clamping and tightening the steel plates.

[0037] Furthermore, there are two or more positioning plates 21, arranged at intervals. Positioning posts 23 are installed at the outer ends of each positioning plate 21. Positioning blocks 22 are formed with sliding holes 24 that slide with the positioning posts 23. A compression spring 25, sleeved on the positioning posts 23, is provided between the positioning plates 21 and the positioning blocks 22. The positioning blocks 22 contact the front sidewall of the steel plate, and under the action of the compression spring 25, they provide a buffering effect, preventing impacts and effectively protecting the steel plate.

[0038] A bottom support plate 4 is provided at the bottom of the central support plate 1, and a bottom drive mechanism 40 is provided below the bottom support plate 4 to drive the drive seat 11 to move along the length direction of the central support plate 1. The bottom drive mechanism 40 includes a bottom drive screw 41 arranged along the length direction of the bottom support plate 4, and a bottom drive sleeve 42 is slidably mounted on the bottom drive screw 41. The bottom drive sleeve 42 is connected to the drive seat 11. When the bottom drive screw 41 rotates, the bottom drive sleeve 42 will engage with the bottom drive screw 41 in a transmission relationship, and the bottom drive sleeve 42 will move along the length direction of the bottom drive screw 41. Since the bottom drive sleeve 42 is connected to the drive seat 11, it can drive the drive seat 11 to move forward or backward.

[0039] Preferably, the drive base 11 is connected to longitudinally arranged side drive plates 43 at both ends, the longitudinal drive plates extend downward, and a transversely arranged transverse drive plate 44 is installed between the two side drive plates 43. The transverse drive plate 44 is connected to the bottom drive screw sleeve 42. The side drive plates 43 are located at both ends of the drive base 11 and will not collide when moving. The bottom between the two side drive plates 43 is connected by the transverse drive plate 44, and the transverse drive plate 44 is connected to the bottom drive screw sleeve 42, thereby realizing the connection between the bottom drive screw sleeve 42 and the drive base 11, and realizing the forward and backward movement of the drive base 11.

[0040] Preferably, the bottom support plate 4 has guide structures on both sides along its length for slidingly supporting the drive seat 11. The guide structures include sliding guide rods 45, and a bottom sleeve seat 46 that slides with the sliding guide rods 45 is installed at the bottom of the drive seat 11. When the drive seat 11 moves, the sliding engagement between the bottom sleeve seat 46 and the sliding guide rods 45 ensures the stability of the drive seat 11's movement.

[0041] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
