Description

Technical Field

[0001] This utility model relates to the field of material storage technology, and in particular to a sealed storage box for water-based coatings. Background Technology

[0002] In paint production, warehousing, and application sites, water-based paints are typically stored in drums. Existing storage methods mostly employ fixed shelves or storage bins, whose positions are fixed and cannot be adjusted. This fixed structure presents several inconveniences in practical use: First, when placing or retrieving paint drums from higher shelves, operators often need to use ladders, stepladders, or other auxiliary tools, which is not only cumbersome but also poses certain safety hazards. Second, during storage and retrieval, personnel need to constantly adjust their positions to adapt to different shelf heights, resulting in high labor intensity and low efficiency. Furthermore, to facilitate retrieval, lower shelves usually have ample space, leading to low vertical space utilization. Although some liftable storage equipment exists on the market, its structure is complex, its cost is high, and it is mostly designed for uniform lifting of entire layers or rows of goods, failing to meet the need for flexible and sequential storage and retrieval of multiple layers and batches of paint drums within a limited space.

[0003] Therefore, a sealed storage box for water-based coatings is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a sealed storage box for water-based coatings.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sealed storage box for water-based coatings, comprising a box body with an opening on the front, a dust cover provided on the top of the box body corresponding to the position of the drive motor, and a filter screen provided on the top of the dust cover.

[0006] As a preferred technical solution of this utility model, the box is provided with a lifting assembly, which includes a number of moving ends arranged in a row, and each moving end is connected to a material rack. The lifting assembly includes a guide rail, and there are two guide rails distributed on the left and right sides of the box. A number of slides are provided on the guide rails, and lifting connectors are connected to the slides. The free end of the lifting connector is connected to the material rack.

[0007] As a preferred technical solution of this utility model, a drive assembly is provided inside the housing. The drive assembly has a number of control terminals corresponding to the number of moving ends. The control terminals are used to drive the corresponding moving ends to rise and fall. A drive motor is also provided on the housing. The control terminals are connected to the drive motor. The drive assembly includes drive connectors. There are several drive connectors connected to the slide block. Several drive screws are rotatably installed on one side of the bottom surface of the housing from front to back. The drive screws pass through the top of the housing. The top surface of the drive connectors on the corresponding side is provided with a threaded hole and several through holes at the position corresponding to the drive screw. Each drive connector is threadedly connected to one drive screw and is fitted into the drive screws at other positions. A drive slide is provided on the bottom surface of the housing opposite to the drive screw. A sliding hole is provided on the drive connector on the corresponding side and is slidably connected to the drive slide.

[0008] As a preferred embodiment of this utility model, the housing is equipped with a switching assembly. This assembly allows the drive shaft of the drive motor to switch between driving different control terminals, causing the material rack to move up and down sequentially under the control of the drive motor. The switching assembly includes a drive shaft rotatably connected to a dust cover. The drive shaft is connected to several drive screws with first bevel gears at their respective positions, and the ends of the drive screws are connected to second bevel gears, which mesh with each other. The end of the drive shaft is connected to a first spur gear, and the drive shaft of the drive motor is connected to a second spur gear, which meshes with each other. The drive shaft is composed of several switching shafts, each corresponding to a first bevel gear. The gear and several switching shafts have circular through holes on their corresponding surfaces, which are interconnected. The switching shaft has a hole corresponding to the inner ring of the first bevel gear, and a telescopic shaft is inserted into the hole. The end of the telescopic shaft is hemispherical. The inner wall of the first bevel gear has a curved groove adapted to the telescopic shaft. A sealing plate is fitted into the inner wall of the switching shaft outside the first bevel gear, and the sealing plate closes the through hole. A rotating shaft is connected to the outer wall of the switching shaft at the position corresponding to the sealing plate. The rotating shaft passes through the switching shaft and is connected to the sealing plate. A sleeve is connected to the outer wall of the switching shaft. A torsion spring is installed in the sleeve. The two ends of the torsion spring are connected to the sleeve and the rotating shaft, respectively. Hydraulic oil is injected into the switching shaft.

[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0014] Example: Figure 1 and Figure 2 As shown, a sealed storage box for water-based coatings includes a box body 1 with an open front. A door 11 is hinged to the front of the box body 1, and an electrical control box 12 integrating control circuitry is fixed to the back. Windows with transparent panels 13 are provided on the left and right sides of the box body 1 to facilitate observation of the coating buckets on the internal storage racks 3. A dust cover 14 is provided on the top of the box body 1 corresponding to the drive unit, and a filter screen 15 is installed on the top of the dust cover 14 for ventilation and dust prevention. A temperature-controlled fan (not shown) is also installed inside the box body 1 as needed. In some embodiments, this fan can be a heating fan or a cooling fan to maintain a suitable temperature inside the box and ensure the quality of the water-based coatings. It should be noted that the enclosure 1 constitutes a sealed and controllable storage environment; the enclosure door 11 facilitates overall storage and retrieval and sealing; the transparent panel 13 enables visual operation and management; the electrical control box 12 provides centralized control and convenient operation; the dust cover 14 and the filter 15 protect the core drive components and extend the equipment's lifespan.

[0015] like Figure 1 and Figure 2 As shown, two vertical guide rails 21 are symmetrically arranged inside the box 1. Several slide blocks 22 are slidably installed on each guide rail 21. The inner side of the slide block 22 is connected to the lifting connector 23 by bolts. The free end of the lifting connector 23 extends forward and connects to the material rack 3. The slide block 22 and the lifting connector 23 constitute the moving end.

[0016] It should be noted that the guide rail 21 and the slide 22 provide precise and low-friction vertical guidance for the lifting and lowering of the material rack 3, ensuring the stability of the lifting and lowering process; at the same time, the guide rail 21, which is symmetrically distributed on the left and right, ensures that the material rack 3 is subjected to balanced force, preventing jamming or shaking due to uneven load, and ensuring the safety and stability of the paint bucket during the lifting and lowering process.

[0017] like Figure 1 and Figure 2 As shown, the drive assembly 4 includes several drive screws 41 that are vertically rotatably mounted on the bottom surface of one side of the housing 1. An L-shaped drive connector 42 is fixed to the right side of each slide 22. The top surface of the horizontal part of the drive connector 42 has an opening. Each drive connector 42 is threadedly connected to a specific drive screw 41 through a threaded hole, while it is slidably fitted into other drive screws 41 through a larger through hole. A drive slide rod 43 is correspondingly provided on the other side of the bottom surface of the housing 1. A sliding hole is opened on the drive connector 42 on the corresponding side to slide with it. The drive screws 41 and the drive connector 42 constitute the control end.

[0018] It should be noted that each material rack 3 is driven by an independent drive screw 41, which realizes the basis of independent control; the opening design of the drive connector 42 allows it to be driven to rise and fall on the connected drive screw 41, while sliding freely on other drive screws 41 without interfering with each other; the drive slide bar 43 provides sliding support on the other side, effectively preventing the material rack 3 from twisting or tilting due to uneven force during the lifting process, ensuring smooth and accurate operation.

[0019] like Figure 1 , Figure 3 and Figure 4As shown, a drive motor 5 is installed on the top surface of the housing 1 below the dust cover 14. The output shaft of the drive motor 5 is equipped with a second spur gear 65. The switching assembly 6 includes a transmission shaft 61 spliced ​​from multiple switching shafts 611. The transmission shaft 61 is rotatably connected to the dust cover 14 via a bearing seat. One end of the transmission shaft 61 is equipped with a first spur gear 64 that meshes with the second spur gear 65. Each switching shaft 611 corresponds to a drive screw 41 and is connected to a first bevel gear 62 via a key. The top end of the drive screw 41 is equipped with a second bevel gear 63 that meshes with the first bevel gear 62. The inner side of the first bevel gear 62 is provided with a curved groove 66. An axial through hole 612 is provided in the switching shaft 611 and they are interconnected. A fixed amount of hydraulic oil is injected into the axial through hole 612. The amount of hydraulic oil injected is controlled so that only one switching shaft can be switched. The telescopic shaft (613) on the switching shaft (611) extends by a certain amount. The switching shaft 611 has a radial hole corresponding to the curved surface groove 66. The telescopic shaft 613 is inserted into the hole. The inner wall of the end of the switching shaft 611 is hinged to a sealing plate 614 through a rotating shaft 615. The outer edge of the sealing plate 614 has a sealing ring. The outer end of the rotating shaft 615 is fitted with a sleeve 616. The sleeve 616 contains a torsion spring 617. One end of the torsion spring 617 is fixed to the sleeve 616, and the other end acts on the rotating shaft 615, so that the sealing plate 614 has a tendency to be normally closed. The torsion spring 617 is a known technology that generates torque or rotational force through elastic deformation. This application selects a torsion spring 617 with greater stiffness, which will not be elaborated here. Initially, only the telescopic shaft 613 of the last switching shaft 611 extends under hydraulic oil pressure and engages with the curved surface groove 66.

[0020] It should be noted that the power of the drive motor 5 is transmitted to the transmission shaft 61 through gears; the switching component 6 is the core of the present invention to realize sequential control. It constitutes a precise automatic sequential switching mechanism through the preset hydraulic oil volume, the extension and retraction of the telescopic shaft 613, the opening and closing of the sealing plate 614 and the reset of the torsion spring 617. It uses mechanical resistance to trigger hydraulic transmission, realizes the automatic switching of the power path, and uses a motor to drive a complex sequence of actions.

[0021] Furthermore, the curved grooves 66 opened on the inner side of each first bevel gear 62 are staggered by one curved groove 66 in circumferential position along the drive shaft 61 from front to back. This ensures that when the previous telescopic shaft 613 is retracted by force and disengages from its corresponding curved groove 66 due to the material rack 3 rising to the limit position, the next telescopic shaft 613, which has just been pushed out by hydraulic oil, rotates to the position directly opposite its corresponding curved groove 66 and then extends to complete the engagement, thereby achieving seamless switching of the power path. To ensure that the relative position of the corresponding telescopic shaft 613 and the curved groove 66 remains consistent with the initial engagement state each time the material rack 3 rises to the top limit position, a limit component (not shown in the figure) is provided inside the housing 1 corresponding to the end point of the rising stroke of each material rack 3 to precisely control the final stopping position of the material rack 3.

[0022] Working principle: In the initial state, all the material racks 3 are located at the bottom. The telescopic shaft 613 of the bottommost switching shaft 611 extends under hydraulic pressure and engages with the curved groove 66. When placing paint buckets, they are stacked starting from the topmost material rack 3. When the topmost rack is full, the drive motor 5 is started to rotate forward. Power is transmitted through the transmission shaft 61, the topmost switching shaft 611, and the telescopic shaft 613 to the first bevel gear 62 and the corresponding drive screw 41, thereby driving the topmost material rack 3 to rise. When the material rack 3 rises to the top limit, the drive screw 41 can no longer rotate, and the resistance increases. At this time, the drive motor 5 continues to rotate, and the force forces the currently extended telescopic shaft 613 to overcome the hydraulic oil pressure and retract towards the shaft center, squeezing the hydraulic oil. The hydraulic oil pressure is transmitted through the through hole 612, overcoming the torque of the torsion spring 617 at the sealing plate 614 in the next switching shaft 611, pushing open the sealing plate 614, and rushing into the chamber of the switching shaft 611, pushing out its telescopic shaft 613 and engaging with the corresponding curved groove 66. At the same time, the original telescopic shaft 613 is completely retracted and disengaged. At this point, the power is automatically switched to the next layer drive screw 41, which can drive the material rack 3 of this layer to rise after placing the paint bucket, thereby freeing up new space for stacking. This cycle is repeated to achieve sequential filling from top to bottom.

[0023] During material retrieval, the process is reversed. The drive motor 5 reverses, and the bottom-level fully loaded material rack 3 descends to the bottom first, freeing up operating space for material retrieval. Once this layer is emptied, it continues to reverse, triggering the switching mechanism to lower the upper-level material rack 3, thus achieving sequential emptying from bottom to top. The entire process is automatic and continuous.

[0024] Therefore, the core objective of this invention is to cleverly achieve on-demand, sequential lifting and lowering of multi-layer storage racks under a single power source through an integrated drive and automatic switching mechanism, perfectly solving the problems of inconvenient access and low space utilization of fixed racks, and achieving labor-saving, efficient, and intelligent storage effects.

[0025] It should be noted that the dimensions of the drive screw 41, the first bevel gear 62, the second bevel gear 63, and the switching shaft 611 in the figure are all examples and can be adjusted in actual applications to consider pressure requirements, etc.

They are only for the purpose of more clearly describing the technical solutions of this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting this invention.

Various substitutions, alterations, and modifications can be conceived without departing from the spirit and scope of the invention.
