Description

Technical Field

[0001] This utility model relates to the field of steel plate transfer technology, and in particular to a steel plate centering 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 directly use a pusher plate to push forward. Since the steel plate is rectangular, direct forward pushing is prone to deviation on both sides, resulting in low shape accuracy of the gravure roller. Utility Model Content

[0004] The purpose of this invention is to provide a steel plate centering 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 mechanism includes a centering frame, which has a first rolling support area for rolling support of the bottom surface of the steel plate, and second rolling support areas that roll with the sides of the steel plate on the left and right sides of the first rolling support area.

[0007] The first rolling support area includes multiple spaced-apart first support rollers.

[0008] The second rolling support area includes multiple spaced second support rollers, which are longitudinally arranged to roll in cooperation with the side of the steel plate; the second support rollers are capable of moving along the width direction of the centering frame; the centering frame is also provided with a push plate that moves along its length direction and a propulsion area for the push plate to move.

[0009] Furthermore: the first rolling support area includes a left rolling support area and a right rolling support area, and multiple first support rollers are respectively installed in the left rolling support area and the right rolling support area.

[0010] Furthermore: the left rolling support area and the right rolling support area each include a support mounting strip arranged along the length of the center frame. The support mounting strip is equipped with multiple spaced movable mounting seats along its length. The first support roller is equipped with rotating shafts at both ends, and the rotating shafts are connected to the movable mounting seats.

[0011] Furthermore: the first support rollers of the left and right rolling support areas are laterally aligned.

The push plate is installed on the top of the propulsion drive seat. The propulsion drive seat is provided with a drive screw sleeve that is in transmission cooperation with the drive screw and a guide sleeve that is in sliding cooperation with the drive guide rod.

[0013] Furthermore: the second rolling support area includes a movable plate located below the first rolling support area, the movable plate being installed on the left and right sides of the first rolling support area respectively, and the second support rollers being installed at intervals on the movable plate, the second support rollers being disposed between two adjacent first support rollers.

[0014] Furthermore: the second rolling support area is provided with an adjustment mechanism for the distance between the two moving plates. The adjustment mechanism includes a pair of parallel spaced teeth. The outer ends of the teeth are connected to the moving plates. A rotatable drive gear is installed between the two teeth.

[0035] The present invention will now be described in detail with reference to the accompanying drawings.

[0036] like Figure 1-4 As shown, a steel plate centering mechanism includes a centering frame 1, which is provided with a first rolling support area 10 that provides rolling support to the bottom surface of the steel plate, and second rolling support areas 3 that are provided on the left and right sides of the first rolling support area 10 to roll and cooperate with the side of the steel plate.

[0037] The first rolling support area 10 includes a plurality of first support rollers 11 arranged at intervals.

[0038] The second rolling support area 3 includes a plurality of spaced second support rollers 31, which are longitudinally arranged and roll in cooperation with the side of the steel plate; the second support rollers 31 are capable of moving along the width direction of the centering frame 1; the centering frame 1 is also provided with a push plate 26 that moves along its length direction and a propulsion area 2 for the push plate 26 to move.

[0039] When winding is required, the steel plate is placed into the first rolling support area 10, and multiple first support rollers 11 roll to support the bottom surface of the steel plate. At the same time, according to the width of the steel plate, the second support rollers 31 in the second rolling support area 3 move laterally to adjust the lateral position so that the second support rollers 31 can roll to contact the side wall of the steel plate. Finally, the push plate 26 moves along the length of the pushing area 2 to push the steel plate into the winding mechanism to form a cylindrical structure, which can prevent the steel plate from shifting to the left or right and ensure high precision of the wound gravure roller.

[0040] Furthermore, the first rolling support area 10 includes a left rolling support area 12 and a right rolling support area 13, with multiple first support rollers 11 respectively installed in the left rolling support area 12 and the right rolling support area 13; the pushing area 2 is located between the left rolling support area 12 and the right rolling support area 13, and the left rolling support area 12 and the right rolling support area 13 respectively provide rolling support to the steel plate through the first support rollers 11. At the same time, since the pushing area 2 is located between the left rolling support area 12 and the right rolling support area 13, the push plate 26 can contact the middle area of ​​the steel plate. When pushing, the area where the push plate 26 contacts the steel plate is subjected to more uniform force, reducing the probability of the steel plate deviating.

[0041] Preferably, a propulsion drive seat 23 is slidably mounted in the propulsion area 2, and a drive screw 21 and a drive guide rod 22 are arranged along the length of the propulsion area 2. A push plate 26 is mounted on the top of the propulsion drive seat 23. The propulsion drive seat 23 is provided with a drive screw sleeve 24 that is in transmission cooperation with the drive screw 21 and a guide sleeve 25 that is in sliding cooperation with the drive guide rod 22. The drive screw 21 rotates under the drive of the motor. The drive screw 21 is in transmission cooperation with the drive screw sleeve 24 of the propulsion drive seat 23. The propulsion drive seat 23 moves forward through the guide sleeve 25 and the drive guide rod 22. The push plate 26 can push the steel plate forward. The steel plate can simultaneously roll with the first support roller 11 and the second support roller 31 and be stably pushed forward into the winding mechanism for the next process.

[0042] The left rolling support area 12 and the right rolling support area 13 each include a support mounting strip 14 arranged along the length of the centering frame 1. Multiple spaced movable mounting seats 15 are mounted on the support mounting strip 14 along its length. A rotating shaft 16 is mounted at both ends of the first support roller 11, and the rotating shaft 16 is connected to the movable mounting seat 15. The rotating shaft 16 is mounted on the movable mounting seat 15, and the two ends of the first support roller 11 are rotatably connected to the rotating shaft 16 through a hole structure, allowing the first support roller 11 to rotate around the rotating shaft 16, facilitating rolling contact with the steel plate.

[0043] The first support rollers 11 of the left rolling support area 12 and the right rolling support area 13 are laterally aligned. The second rolling support area 3 includes a movable plate 32 located below the first rolling support area 10. The movable plate 32 is installed on the left and right sides of the first rolling support area 10, and the second support rollers 31 are installed at intervals on the movable plate 32, with the second support rollers 31 positioned between two adjacent first support rollers 11. Since the two adjacent first support rollers 11 are arranged at intervals and parallel to each other, a gap can be formed for the second support rollers 31 to move laterally, thereby adjusting the distance between the two movable plates 32. According to the width of the steel plate, it can adaptively roll and cooperate with the left and right side walls of the steel plate, guiding the rolling of the steel plate side and preventing left and right deviation when pushing forward.

[0044] Furthermore, the top of the movable plate 32 is provided with a plurality of upright support columns 33, and a support shaft 34 is installed on the top of the support column 33. The second support roller 31 is rotatably sleeved on the support shaft 34. The second support roller 31 can rotate on the support shaft 34. When the steel plate is pushed forward, the second support roller 31 rotatably rolls with the side wall of the steel plate.

[0045] Specifically, the second rolling support area 3 is equipped with an adjustment mechanism 4 that drives the distance between the two moving plates 32. The adjustment mechanism 4 includes a pair of parallel spaced toothed conditions 41. The outer ends of the toothed conditions 41 are connected to the moving plates 32. A rotatable drive gear 42 is installed between the two toothed conditions 41. The drive gear 42 meshes with both toothed conditions 41 to drive the two toothed conditions 41 to move relative to each other. When adjusting the distance between the two moving plates 32, the drive gear 42 rotates and meshes with both toothed conditions 41, causing the two toothed conditions 41 to move relative to each other. The moving plates 32 installed at the outer ends of the toothed conditions 41 can move, thereby adjusting the distance between the two moving plates 32, which facilitates the rolling contact between the second support roller 31 and the side wall of the steel plate.

[0046] Furthermore, the second rolling support area 3 is provided with a horizontally arranged bottom support plate 43. A drive motor 46 is mounted on the bottom of the bottom support plate 43, and a bottom drive hole 44 is opened in the bottom support plate 43. A drive shaft 45 is mounted on the top of the bottom drive hole 44, and a drive gear 42 is rotatably mounted on the drive shaft 45. The drive end of the drive motor 46 is connected to the drive shaft 45 to drive the drive gear 42 mounted on the drive shaft 45 to rotate, thereby adjusting the distance between the two moving plates 32.

[0047] Furthermore, the bottom support plate 43 is provided with a longitudinally arranged pressure plate 47, which is installed parallel to the outside of the tooth condition 41. The pressure plate 47 is equipped with a longitudinally arranged guide roller 48, the bottom of which rolls in contact with the top surface of the tooth condition 41 to prevent the tooth condition 41 from tilting up during movement.

[0048] Furthermore, the adjusting mechanism 4 also includes a bottom guide rod 35 arranged along the length of the second rolling support area 3, and a bottom sliding seat 36 that slides with the bottom guide rod 35 is installed at the bottom of the moving plate 32. When the gear condition 41 moves, the bottom sliding seat 36 installed at the bottom of the moving plate 32 slides with the bottom guide rod 35 through a sleeve structure to ensure the stability of the moving plate 32 when it moves laterally and to prevent any deviation. The steel plate can then roll stably with the second support roller 31.

[0049] 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.
