Description

Technical Field

[0001] This utility model relates to the technical field of POM board production equipment, and in particular to a storage rack for POM board production. Background Technology

[0002] POM (Polyoxymethylene) sheets are high-performance engineering plastic sheets made from polyoxymethylene resin through extrusion or compression molding. They possess excellent mechanical strength, wear resistance, fatigue resistance, and dimensional stability, and are widely used in the manufacturing of automotive parts, precision gears, electronic components, and industrial guide rails. During production, POM sheets are typically formed in strip or sheet form and must be stored in a constant temperature and dry environment to maintain material properties and prevent warping or deformation due to moisture absorption or temperature changes.

[0003] After POM boards are produced, they need to be stacked for storage. Because POM boards are relatively long (commonly 1-3 meters) and have limited thickness (usually 5-50mm), direct stacking can easily cause the boards to tilt or collapse due to the high center of gravity, resulting in surface scratches or even structural damage. Therefore, forklift pallets are used for auxiliary storage. The POM boards are placed on the forklift pallet, and then the forklift is used to transfer the pallet containing the POM boards to a storage rack. However, this method has the following problems:

[0004] 1. Operation relies on human experience: Forklift operators need to precisely control the spacing between forklift pallets to prevent collisions, which requires a high level of operational proficiency, resulting in high labor costs and unstable efficiency.

[0005] 2. Significant space waste: To avoid collisions between forklift pallets and existing forklift pallets and POMs when placing them on storage racks, a safe distance must be ensured. A large gap (usually ≥200mm) must be reserved between adjacent pallets, resulting in low utilization of horizontal rack space and failure to meet production needs. Utility Model Content

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a storage rack for POM board production that can adjust the position of forklift pallets, improve space utilization, and is easy to operate.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A storage rack for POM board production includes at least one shelf unit, with adjacent shelf units arranged side by side; each shelf unit includes a base, four vertically arranged columns fixedly installed on the base, and several shelves; the four columns are arranged in a rectangular shape; each shelf includes two opposite side panels and two opposite side rods, the two side panels and two side rods forming a rectangular structure, and the ends of the side panels and side rods are fixedly connected to the columns; several spaced-apart support rods are fixed between the two side rods, and three support blocks are fixedly installed on each support rod, with gaps between adjacent support blocks; two sets of walking structures are arranged between the two side panels, and the walking structures are located within the gaps between the two support blocks.

[0009] In this way, the base and columns form the foundation for the shelving unit. POM boards are placed on forklift pallets, which are then moved onto the shelving unit by the forklift. The shelving unit supports the forklift pallets. The forklift then places the pallets on the traveling mechanism of the shelving unit, which moves the pallets with POM boards, ensuring that the pallets are neatly stacked on the shelving unit, making efficient use of space and preventing collisions between the pallets and the POM boards.

[0010] Preferably, the walking structure includes two screws, two walking blocks, and a lifting plate. The two ends of the screws are respectively connected to two side plates via bearings. A drive assembly for rotating the screws is installed on the side plates. Nut blocks are threadedly connected to the two screws. The walking blocks have mounting holes and clearance holes. The nut blocks are fixedly installed in the mounting holes of the walking blocks. The clearance holes are offset and allow clearance for the screws. The mounting holes on the two walking blocks are offset. A guide support assembly for guiding and supporting the walking blocks is also provided between the two side plates. The lifting plate is connected to the walking blocks via the lifting assembly.

[0011] Preferably, the drive assembly includes a servo motor fixedly mounted on the side plate, an active bevel gear fixedly mounted on the output shaft of the servo motor, and a driven bevel gear meshing with the active bevel gear fixedly mounted on the end of the screw.

[0012] Preferably, the guide support assembly includes two guide rods, the two ends of which are fixedly connected to two end plates respectively, and the movable block has guide holes that slide with the guide rods.

[0013] Preferably, the lifting assembly includes electric push rods fixedly installed on both sides of the walking block, and a battery for electrical connection with the electric push rods is fixedly installed on the walking block. The telescopic end of the electric push rod is fixedly connected to the lifting plate. When the electric push rod is in the retracted state, the upper surface of the lifting plate is lower than the upper surface of the support block.

[0014] Preferably, the ends of the side plate and the side rod are welded to the column.

[0015] In summary, this storage rack for POM board production has the advantages of being able to adjust the position of forklift pallets, improving space utilization, and being easy to operate. Attached Figure Description

[0023] like Figure 1-6 As shown, a storage rack for POM board production includes at least one shelf unit 1, with adjacent shelf units arranged side by side; each shelf unit includes a base 2, four vertically arranged columns 3 fixedly installed on the base, and several shelves; the four columns are arranged in a rectangular shape; each shelf includes two opposite side plates 4 and two opposite side rods 5, the two side plates and two side rods forming a rectangular structure, and the ends of the side plates and side rods are fixedly connected to the columns; several spaced support rods 6 are fixed between the two side rods, and three support blocks 7 are fixedly installed on the support rods, with gaps between adjacent support blocks; two sets of walking structures 8 are arranged between the two side plates, and the walking structures are arranged within the gaps between the two support blocks.

[0024] In this way, the base and columns form the foundation for the shelving unit. POM boards are placed on the forklift pallet, which is then placed onto the shelving unit by the forklift, which provides support. The forklift places the pallet on two sets of traveling mechanisms on the shelving unit, which move the pallet with the POM boards, ensuring the pallets are neatly stacked on the shelving unit, making efficient use of space, and preventing collisions between the pallets and the POM boards.

[0025] In implementation, the walking structure includes two screws 9, two walking blocks 10, and a lifting plate 11. The two ends of the screws are respectively connected to the two side plates via bearings. A drive assembly for rotating the screws is installed on the side plates. Nut blocks 12 are threaded onto the two screws respectively. The walking blocks have mounting holes and clearance holes. The nut blocks are fixedly installed in the mounting holes of the walking blocks. The clearance holes are staggered and make way for the screws. The mounting holes on the two walking blocks are staggered, and the clearance holes make way for the other screw to avoid interference. A guide support assembly for guiding and supporting the walking blocks is also provided between the two side plates. The lifting plate is connected to the walking blocks via the lifting assembly.

[0026] In this way, the traveling structure uses two screws, each with its own drive assembly. A single screw drives the movement of a single traveling block, allowing for independent adjustment of the two traveling blocks' positions. This enables the use of forklift pallets of different sizes, increasing its applicability. It also allows for pallet transfer between two individual rack units. When transferring a forklift pallet, the lifting assembly raises the lifting plate above the support block, lifting the pallet. The traveling blocks then move the pallet. Once in position, the lifting assembly lowers the lifting block below the support block, using the support block to support the pallet. The lifting block can then move with the traveling blocks to the outside of the pallet for easy reuse.

[0027] In implementation, the drive assembly includes a servo motor 13 fixedly mounted on a side plate, a driving bevel gear 14 fixedly mounted on the output shaft of the servo motor, and a driven bevel gear 15 meshing with the driving bevel gear fixedly mounted on the end of the screw. The servo motor drives the driving bevel gear to rotate, and the meshing of the driving and driven bevel gears drives the screw to rotate.

[0028] In implementation, the guide support assembly includes two guide rods 16, with each end of the guide rod fixedly connected to two end plates. The moving block has guide holes that slide with the guide rods. The guide rods provide support and guidance for the moving block.

[0029] In implementation, the lifting assembly includes electric push rods 17 fixedly installed on both sides of the traveling block. A battery for electrical connection with the electric push rods is fixedly installed on the traveling block. The telescopic end of the electric push rod is fixedly connected to the lifting plate. When the electric push rod is in the retracted state, the upper surface of the lifting plate is lower than the upper surface of the support block. The electric push rod drives the lifting block to rise, resulting in a simple structure and ease of use.

[0030] In practice, the ends of the side plates and side rods are welded to the columns. This facilitates manufacturing.

[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
