Description

Technical Field

[0001] This utility model belongs to the field of printing technology, and specifically relates to a pre-printing roller storage rack. Background Technology

[0002] In the packaging and printing industry, pre-printing rollers are one of the core components for achieving high-speed, high-quality printing, and are widely used in the pre-printing process of packaging products such as corrugated boxes and color boxes. The surface of the pre-printing roller is precision-machined to form specific printing patterns, and the flatness and integrity of its printed surface directly determine the quality of the final printed product. At the same time, pre-printing rollers are usually made of metal, and to ensure printing accuracy and structural stability, their overall weight is relatively large, with a single roller typically weighing tens or even hundreds of kilograms.

[0003] Because the pre-printing roller is heavy, it cannot be handled manually. During production, storage and turnover, it must be lifted by cranes or other lifting equipment. Moreover, its printing surface is extremely delicate. Once it is bumped, worn or scratched, it will directly cause the printed pattern to be distorted, fail to meet production requirements, or even cause the entire roller to be scrapped. Therefore, it is necessary to strictly avoid contact or collision between the printing surface and other objects during storage and handling.

[0004] Currently, triangular supports are commonly used in the industry as storage devices for pre-printing rollers. These triangular supports are typically made of welded steel or fixed wood, forming a triangular structure. The pre-printing rollers need to be placed horizontally on the two inclined sides of the triangular support. To facilitate the alignment, placement, and retrieval of the pre-printing rollers by operators assisting with crane operations, and to avoid difficulties in manual assistance or safety hazards due to excessive height of the supports, the height of the triangular supports is generally controlled within two meters. Due to the limitations of height and the inclination angle of the sides, each triangular support can only hold three to four pre-printing rollers on a single side, limiting the overall storage capacity of a single support. With the rapid development of the packaging and printing industry, the demand for pre-printing rollers is increasing. Multiple specifications and batches of pre-printing rollers need to be stored simultaneously. The existing storage space of triangular supports can no longer meet the large-scale storage needs of enterprises, forcing them to increase the number of supports to solve the storage problem. This not only occupies a large amount of workshop production space but also increases the equipment investment costs for enterprises.

[0005] Furthermore, because the existing triangular support has an inclined waist surface, the pre-printing rollers are placed in layers along this inclined direction. When accessing the lower-layer pre-printing rollers, the crane must move the rollers along this inclined direction, making them highly susceptible to contact or collision with the rollers above them. Even with careful crane control, it is difficult to completely avoid damage to the printed surface caused by lifting accuracy deviations or roller wobbling. This not only affects the service life of the pre-printing rollers but also increases the risk of production delays and costs due to roller repair or replacement. Utility Model Content

[0006] The present invention aims to provide a pre-printing roller storage rack, which is mainly used to solve the technical problem of small storage space in the existing technology.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pre-printing roller storage rack includes a support frame, with a storage device for storing pre-printing rollers rotatably connected to the middle of the support frame. The storage device includes a support rod with both ends rotatably connected to the support frame. Two symmetrically arranged turntables are fixedly connected to the middle of the support rods. Each turntable includes a connecting rod equidistantly fixed to the outer circumference of the support rod. A plurality of storage components for placing pre-printing rollers are rotatably connected to the connecting rod.

[0008] Preferably, the connecting rods are one, two, three, or four.

[0009] Preferably, the storage assembly includes a fixed rod that is perpendicularly fixed to the connecting rod, and a rotating block is rotatably connected to the fixed rod. The lower end of the rotating block is bent into a hook that can accommodate the end of the pre-printing roller.

[0010] Preferably, the storage device includes a fixing ring coaxially arranged with the support rod, and the fixing ring is fixed to the end of the connecting rod away from the support rod.

[0011] Preferably, a pad is also fixed on the fixed rod, and the pad is disposed between the rotating block and the connecting rod.

[0012] Preferably, one end of the support rod is fixed with a rotating disk for rotating the support rod.

[0013] Preferably, the rotating disk has equidistant circumferentially distributed insertion holes on its surface, and the bracket has limit holes, with a limit rod passing through both the insertion holes and the limit holes.

[0014] Preferably, the end of the limiting rod that passes through the limiting hole is tapered.

[0015] The beneficial effects of this utility model are as follows: (1) This device stores pre-printing rollers by rotating a storage unit mounted on a support. Specifically, at least one connecting rod is first rotated to a horizontal position, and the storage components are arranged horizontally. Then, with the help of a lifting device and manual intervention, the pre-printing roller is hoisted between two symmetrically corresponding storage components, and the two metal ends of the pre-printing roller are placed on the storage components. This process is repeated until all storage components contain pre-printing rollers. During rotation, because the storage components are rotatable, the ends of the pre-printing rollers only move on the same plane and do not rotate, regardless of how they are rotated. When the pre-printing roller needs to be retrieved, one of the connecting rods is rotated to a horizontal position, and then the pre-printing roller is lifted and transferred using a lifting device and manual intervention. Compared to traditional storage devices, this device provides a larger storage space.

[0016] (2) Because the number of connecting rods is controlled between 1 and 4, and the included angle between adjacent connecting rods is greater than or equal to 90°, in the process of storing and retrieving pre-printed rollers, since the corresponding connecting rods are set horizontally, the movement trajectory of the pre-printed rollers is vertical up and down, which will not interfere with other connecting rods or the pre-printed rollers on the same connecting rod. However, the traditional triangular placement frame may interfere with the pre-printed rollers above the placement position when lifting or placing the pre-printed rollers, causing the pre-printed rollers to collide and be damaged.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] To ensure the clarity and replicability of the implementation process of this utility model, the following provides a detailed description of the storage rack for facilitating the storage and retrieval of pre-printing rollers, in conjunction with specific structural details and connection relationships: like Figures 1-4As shown, the storage rack for facilitating the storage and retrieval of the pre-printing roller 8 is first equipped with a support 1. This support 1 serves as the supporting foundation for the entire device and is generally inverted U-shaped. It includes a bottom fixed plate and upright plates on both sides of the fixed plate, and the side projection of the support 1 is trapezoidal, making the support 1 more stable on the ground. A storage device is rotatably connected to the middle of the support 1 to realize the storage and rotation adjustment of the pre-printing roller 8. The storage device includes a support rod 2, and the two ends of the support rod 2 are rotatably connected to the left and right upright plates of the support 1 through deep groove ball bearings, thereby ensuring that the support rod 2 can rotate stably on the support 1 with low friction.

[0025] Two symmetrically arranged turntables are fixedly connected to the support rod 2 at the middle between the two upright plates. The two turntables are located near the two ends of the support rod 2 and are fixed to the support rod 2 as a whole by welding, rotating synchronously with the support rod 2. Each turntable includes a connecting rod 31. In different embodiments, the number of connecting rods 31 can be one, two, three, or four, and each connecting rod 31 is fixed at equal intervals on the outer circumference of the support rod 2 and connected by welding. When there are two connecting rods 31, the two rods are symmetrically distributed at 180°. When there are three, they are distributed at 120°. When there are four, they are distributed at 90°, ensuring that the included angle between adjacent connecting rods 31 is greater than or equal to 90°, thus reserving sufficient operating space for the storage and retrieval of the pre-printing roller 8. A fixing ring 32 is fixed to the end of each connecting rod 31 away from the support rod 2. The fixing ring 32 is welded to the end of each connecting rod 31 away from the support rod 2. It is coaxial with the support rod 2 and its function is to enhance the connection strength between each connecting rod 31 and prevent the connecting rod 31 from bending and deforming when bearing the weight of the pre-printing roller 8.

[0026] Several storage components are rotatably connected to each connecting rod 31. These storage components are equidistantly distributed along the length of the connecting rod 31, with the spacing between adjacent storage components greater than the length of the pre-printing roller 8 to prevent interference during storage and retrieval. Figure 4As shown, the storage assembly includes a fixing rod 33, which is perpendicular to the connecting rod 31 and fixed to the side of the connecting rod 31 by welding, pointing towards the direction between the two storage devices. The number of fixing rods 33 fixed on each connecting rod 31 is set according to the storage requirements of the pre-printing roller 8. A rotating block 35 is sleeved on the fixing rod 33 on the side of the pad 34 away from the connecting rod 31, and the rotating block 35 is rotatably connected to the fixing rod 33. The lower end of the rotating block 35 is bent to form a hook 36, which has a semi-circular arc structure. Its inner diameter matches the diameter of the metal shaft head at the end of the pre-printing roller 8, ensuring that the metal end of the pre-printing roller 8 can be stably placed in the hook 36 without sliding left or right. A pad 34 is also fixed on the fixed rod 33. The pad 34 is fixed on the fixed rod 33 and is located between the rotating block 35 and the connecting rod 31. It is used to adjust the distance between the corresponding rotating plates on the two storage components, and at the same time, to keep the rotating plate and the connecting rod 31 at a sufficient distance. The rotating block 35 is pushed out, so that the metal shaft head of the preprint roller 8 can be easily placed in the hook 36 from top to bottom.

[0027] The spacing between adjacent storage components is greater than the sum of the lengths of the two rotating blocks 35 and the radius of the pre-printing roller 8. During the rotation of the support rod 2, the pre-printing rollers 8 on the same connecting rod 31 will not interfere with each other.

[0028] like Figure 2 As shown, a rotating disk 4 is fixed to one end of the support rod 2. The rotating disk 4 is located on the outside of the bracket 1 and is fixedly connected to the end of the support rod 2 by welding, allowing the operator to drive the support rod 2 to rotate. The rotating disk 4 includes equidistantly distributed circumferential insertion holes 5 on its surface. A limiting hole 6 is provided on the upright plate of the bracket 1 near the rotating disk 4. When the support rod 2 rotates to a horizontal position on a certain connecting rod 31, a certain insertion hole 5 is exactly aligned with the limiting hole 6. The limiting rod 7 is a cylindrical rod that can pass through the insertion hole 5 and the limiting hole 6, thereby fixing the position of the support rod 2 and preventing the support rod 2 from rotating accidentally when storing or retrieving the pre-printing roller 8. The end of the limiting rod 7 that passes through the limiting hole 6 is set in a conical shape. The conical structure facilitates the quick insertion of the limiting rod 7 into the limiting hole 6 and the insertion hole 5, improving operational convenience.

[0029] The diameters of the insertion hole 5 and the limiting rod 7 are matched so that the rotating disk 4 will not wobble when the limiting rod 7 is inserted into the insertion hole 5 and the limiting hole 6.

[0030] The specific implementation process of this device is as follows: When it is necessary to store the pre-printing roller 8, first pull out the limiting rod 7, hold the second fixing ring 32 and rotate the rotating disk 4, drive the support rod 2 and the turntable to rotate synchronously, rotate one of the connecting rods 31 to the horizontal state, at this time the insertion hole 5 is aligned with the limiting hole 6 on the bracket 1, insert the limiting rod 7 to fix the support rod 2. At this point, the storage components on the horizontal connecting rod 31 are arranged horizontally. The operator uses a crane in the factory to lift the pre-printing roller 8, adjusts its position so that the metal shaft ends at both ends are aligned with the hooks 36 of the corresponding storage components on the two symmetrical turntables, and slowly lowers the crane so that the metal shaft ends of the pre-printing roller 8 fall into the hooks 36. During this process, no matter how the support rod 2 rotates, the rotating block 35 will rotate around the pivot pin on the fixed rod 33 under the weight of the pre-printing roller 8, always keeping the hooks 36 facing downwards. That is, no matter how the support rod 2 is rotated subsequently, the rotation of the rotating block 35 will always cause the end of the pre-printing roller 8 to translate in the same vertical plane without circumferential rotation, so that the pre-printing rollers 8 will not interfere with each other during rotation. Repeat the above operation, rotating each connecting rod 31 to the horizontal and fixing it in sequence, and placing the pre-printing roller 8 on the corresponding storage component until all storage components are loaded.

[0031] When the pre-printing roller 8 needs to be retrieved, pull out the limiting rod 7, rotate the rotating disk 4 to rotate the connecting rod 31 containing the target pre-printing roller 8 to a horizontal state, and then insert the limiting rod 7 again to fix the support rod 2; then hook the middle of the pre-printing roller 8 with the lifting hook, slowly lift it, so that the end of the pre-printing roller 8 is separated from the hook 36 of the storage component, and the pre-printing roller 8 can be transferred to the designated position.

[0032] In the above implementation process, since the included angle between the connecting rods 31 is greater than or equal to 90° (the attached figure shows the structure when there are 4 connecting rods 31, and the included angle between adjacent connecting rods 31 is 90°), and the pre-printing roller 8 moves in the vertical direction when it is stored and retrieved, interference with other connecting rods 31 and the pre-printing roller 8 is effectively avoided. At the same time, the connection method and structural parameters of each component are clear, and those skilled in the art can select appropriate materials according to actual needs for processing and assembly to completely replicate the device.
