Description

Technical Field

[0001] This utility model belongs to the field of artificial leather storage technology, specifically relating to a storage device for the production of PU artificial leather. Background Technology

[0002] In the production process of PU artificial leather, the rational design of storage devices plays a crucial role in ensuring product quality and production efficiency. PU (polyurethane) artificial leather is a high-performance synthetic leather made from polyurethane resin and various chemical reagents through complex chemical reactions.

[0003] The placement plates of existing storage devices used in PU artificial leather production are mostly fixed and cannot be moved outwards. As a result, the storage and retrieval of PU artificial leather rolls must be completed by lifting them through the opening of the box, which is not very convenient. At the same time, the placement plates lack targeted limiting structures, which makes the stability of the rolls insufficient after placement. During the movement of the device, axial displacement or shaking is likely to occur, which not only affects the storage and retrieval efficiency, but may also cause problems such as scratches on the surface of the rolls and edge deformation. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a storage device for PU artificial leather production, which features an outwardly movable placement plate for easy material handling and prevents the PU artificial leather from shifting or shaking on the placement plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a storage device for PU artificial leather production, comprising a storage box, a door hinged to the front end of the storage box, several placement plates spaced vertically inside the storage box, protrusions integrally formed on the rear sides of both ends of the placement plates, slide rails that slide and engage with the protrusions on the inner end walls of the storage box, pull grooves for easy pulling on the front end face of the placement plates, and several arc-shaped grooves adapted to PU artificial leather rolls on the upper end face of the placement plates; support plates are fixed to the inner end walls of the storage box at positions corresponding to each placement plate, and several rolling grooves are formed on the upper end face of the support plates, with ball bearings rotatably embedded in the rolling grooves, and the upper ends of the ball bearings rolling and adhering to the lower end face of the placement plates.

[0006] Preferably, two side plates are fixed to the inner side walls of one end of the storage box at the corresponding positions of each placement plate. A screw is rotatably connected between the two side plates on the same side, and a guide rod is fixed between the two side plates on the other side. A movable plate is provided on the upper side between the guide rod and the screw. A fixing rod is fixed to the end of the movable plate near the placement plate at the corresponding position of each arc groove. Arc rods are symmetrically fixed on both sides of the surface of the fixing rod.

[0007] Preferably, self-locking casters are symmetrically installed on both sides of the lower end face of the storage box, and several triangular reinforcing plates are fixed between the support plate and the inner wall of the storage box; several connecting rods are fixed between two adjacent fixed rods.

[0008] Preferably, the door is fitted with a transparent observation window, the two ends of the placement plate slide against the inner wall of the storage box, and the upper surface of the ball bearing protrudes from the upper surface of the support plate and rolls in close contact with the lower surface of the placement plate.

[0009] Preferably, the lower end of the screw passes through the lower side plate and is fixed with a knob. One side of the moving plate has a threaded hole that engages with the screw thread, and the other side has a sliding hole that engages with the guide rod.

[0010] Preferably, the connecting rod and the fixing rod are fixed by welding, the lower end of the arc rod is provided with a smooth arc structure on both sides, and a rubber anti-slip pad is attached to the lower end of the arc rod, and the surface of the anti-slip pad is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention optimizes the storage of PU artificial leather rolls through the synergistic combination of a pull-out placement plate and a precise pressing structure. During retrieval, the placement plate is pulled using a groove, with protrusions at both ends forming sliding limits with the storage box's slide rail. Ball bearings on the support plate reduce friction through rolling contact, allowing the placement plate to move smoothly. The roll can be precisely placed into or removed from the arc-shaped groove. After operation, simply reset and close the door. This significantly reduces storage and retrieval difficulty and improves operational convenience. During roll storage, rotating the screw drives the moving plate vertically downwards along the guide rod. The guide rod ensures smooth movement without deviation. The moving plate, through a fixed rod, drives the arc-shaped rod to precisely press the roll, effectively constraining its freedom of movement and preventing displacement and shaking of the roll during device movement. This ensures storage stability, prevents surface scratches and edge deformation, and meets the requirements for efficient and stable storage. Attached Figure Description

[0013] 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.

[0014] Please see Figure 1-4 The present invention provides the following technical solution: a storage device for the production of PU artificial leather, comprising a storage box 1, a door 4 hinged to the front end of the storage box 1, a plurality of placement plates 3 arranged vertically at intervals inside the storage box 1, protrusions 7 integrally formed on the rear sides of both ends of the placement plates 3, slide rails 8 that slide and cooperate with the protrusions 7 on the inner end walls of the storage box 1, a pull groove 5 for easy pulling on the front end face of the placement plates 3, and a plurality of arc-shaped grooves 6 adapted to PU artificial leather rolls on the upper end face of the placement plates 3; support plates 9 are fixed at corresponding positions on the inner end walls of the storage box 1 and each placement plate 3, and a plurality of rolling grooves are opened on the upper end face of the support plates 9, with ball bearings 10 rotatably embedded in the rolling grooves, and the upper end of the ball bearings 10 rolling and adhering to the lower end face of the placement plates 3.

[0015] Specifically, two side plates 12 are fixed to the two side walls of one end of the storage box 1 at the corresponding positions of each placement plate 3. A screw 13 is rotatably connected between the two side plates 12 on the same side, and a guide rod 17 is fixed between the two side plates 12 on the other side. A movable plate 14 is provided on the upper side between the guide rod 17 and the screw 13. A fixing rod 15 is fixed to the end of the movable plate 14 near the placement plate 3 at the corresponding positions of each arc groove 6. Arc rods 16 are symmetrically fixed on both sides of the surface of the fixing rod 15.

[0016] By adopting the above technical solution, when the PU artificial leather roll is placed in the arc-shaped groove 6 for storage, rotating the screw 13 can drive the moving plate 14 to move vertically downward along the guide rod 17. The guide rod 17 forms a lateral limit on the moving plate 14 to ensure the stability of the movement. During the downward movement of the moving plate 14, the fixed rod 15 simultaneously drives the arc-shaped rod 16 to approach the surface of the roll. Finally, the arc-shaped rod 16 forms a precise pressing and positioning of the roll in the arc-shaped groove 6. This limiting structure can effectively constrain the degree of freedom of the roll, avoid axial displacement or shaking of the roll during the movement of the device, ensure the stability of the roll storage, and prevent surface scratches or edge deformation.

[0017] Specifically, self-locking casters 2 are symmetrically installed on both sides of the lower end face of storage box 1, and several triangular reinforcing plates 11 are fixed between the support plate 9 and the inner wall of storage box 1; several connecting rods 18 are fixed between two adjacent fixed rods 15.

[0018] By adopting the above technical solutions, the self-locking caster 2 enables the device to move flexibly and be positioned stably, adapting to the needs of multi-station production. The triangular reinforcing plate 11 strengthens the load-bearing rigidity of the support plate 9, and the connecting rod 18 enhances the overall integrity of the limiting structure, ensuring storage and movement safety.

[0019] Specifically, the door 4 is fitted with a transparent observation window, the two sides of the placement plate 3 slide against the inner wall of the storage box 1, and the upper surface of the ball bearing 10 protrudes from the upper surface of the support plate 9 and rolls in close contact with the lower surface of the placement plate 3.

[0020] By adopting the above technical solutions, the transparent observation window makes it easy to intuitively view the status of the roll material, and the sliding bonding and rolling design of the ball bearing 10 ensures smooth movement of the placement plate 3 and reduces frictional wear.

[0021] Specifically, the lower end of the screw 13 passes through the lower side plate 12 and is fixed with a knob. The movable plate 14 has a threaded hole on one side that is threaded to the screw 13, and a sliding hole on the other side that is slidably engaged with the guide rod 17.

[0022] By adopting the above technical solution, the knob facilitates manual and precise adjustment of the screw 13, and the threaded transmission and guide rod 17 work together to ensure the smooth lifting and lowering of the moving plate 14, thereby achieving reliable pressing and positioning of the roll material.

[0023] Specifically, the connecting rod 18 and the fixing rod 15 are fixed by welding. The lower ends of the arc rod 16 are set with smooth arc structures on both sides, and the lower ends of the arc rod 16 are fitted with rubber anti-slip pads with anti-slip textures on the surface.

[0024] By adopting the above technical solution, the connection strength of the welding and fixing of the connecting rod 18 and the fixing rod 15 is enhanced, ensuring the stability of the limiting structure. The smooth arc shape and the rubber anti-slip pad are adapted to the shape of the roll material, and the anti-slip texture increases the friction resistance, achieving reliable positioning and preventing scratches.

[0025] The working principle and usage process of this utility model: When using the storage device for PU artificial leather production, the device is installed in a suitable position. When it is necessary to take or put in PU artificial leather rolls, the pull force is applied through the groove 5 at the front end of the placement plate 3, which can drive the placement plate 3 to move outward along the slide rail 8 on the inner wall of the storage box 1. The protrusions 7 at both ends form a sliding limit engagement with the slide rail 8. At the same time, the ball bearings 10 at the upper end of the support plate 9 roll into rolling contact with the lower end face of the placement plate 3, forming a rolling support to reduce the translational friction, so that the placement plate 3 can be moved out of the storage box 1 smoothly. At this time, the PU artificial leather rolls can be placed into the arc groove 6 of the placement plate 3, or the rolls can be taken out from the arc groove 6. After the operation is completed, push the placement plate 3 back to slide into the storage box 1, and close the box door 4 to complete the storage and retrieval process. This structure, through the pull-out design of the placement plate 3, greatly reduces the difficulty of the roll storage and retrieval operation and improves the convenience of operation.

[0026] When the PU artificial leather roll is stored in the arc-shaped groove 6, rotating the screw 13 can drive the moving plate 14 to move vertically downward along the guide rod 17. The guide rod 17 forms a lateral limit on the moving plate 14 to ensure the smoothness of the movement. During the downward movement of the moving plate 14, the fixed rod 15 simultaneously drives the arc-shaped rod 16 to approach the surface of the roll. Finally, the arc-shaped rod 16 forms a precise pressing and positioning of the roll in the arc-shaped groove 6. This limiting structure can effectively constrain the degree of freedom of the roll, prevent the roll from axial displacement or shaking during the movement of the device, ensure the stability of the roll storage, and prevent surface scratches or edge deformation.

[0027] 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.
