Technical Field
[0001] This utility model relates to the field of finished paper roll storage technology, specifically a finished paper roll storage device. Background Technology
[0002] This invention relates to the field of finished paper roll storage technology, specifically to a device for storing finished paper rolls. Paper rolls are important raw materials in industries such as tobacco and food packaging, and their storage and transportation require maintaining a stable state to avoid structural deformation or surface damage.
[0003] Traditional paper roll storage devices typically employ a simple box structure, with the paper roll supported by a bracket. However, this design presents several problems in practical applications. For instance, traditional devices lack effective positioning and fixing structures. In existing technologies, the paper roll is positioned solely by support points at both ends of the bracket, making it prone to rolling or displacement when subjected to external impacts or tilting.
[0004] To address the above problems, the present invention provides a novel storage device for finished paper rolls. Utility Model Content
[0005] The purpose of this utility model is to provide a finished paper roll storage device, which has the advantages of stable structure, reliable positioning and convenient operation, and solves the problem that the paper roll is easily rolled or displaced by external impact due to the lack of an effective positioning structure in traditional storage devices.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a paper roll finished product storage device, including a placement compartment, a support movably placed in the placement compartment, a cover being rotatably installed on the top of the placement compartment via a hinge, a first groove being formed on the upper surface of the placement compartment, a second groove being formed on the placement compartment at the front end of the first groove, and a limiting component being movably installed in the second groove;
[0007] The limiting component includes a base frame, with a limiting plate fixedly installed on the inner side of the base frame. The two limiting plates are slidably installed in the second groove, and a positioning component is movably installed at the bottom of the limiting component.
[0008] The positioning component includes a base plate, on which a connecting spring is elastically mounted, and the top of the connecting spring is elastically connected to the bottom of the base frame.
[0009] Preferably, the support is wound with a finished paper roll, and the two ends of the support are respectively movably placed in the first groove.
[0010] In the design, by placing the two ends of the support for the finished paper roll into the first groove respectively, the horizontal stability of the paper roll and the convenient picking and putting function are achieved.
[0011] The first groove is designed to match the diameter of the support shaft of the bracket, ensuring that the bracket is naturally aligned when placed and forming a stable support reference surface;
[0012] The movable placement allows the bracket to slide along the first groove, facilitating quick loading and unloading of paper rolls while avoiding wear and tear on the bracket caused by traditional fixed installation methods.
[0013] Preferably, a handle is fixedly installed on the cover, and an acrylic observation window is embedded in the upper end face of the cover.
[0014] In the design, by fixing a handle to the cover and embedding an acrylic observation window, the device can be easily transported and its storage status can be visualized and monitored.
[0015] The handle features an ergonomic curve design and a non-slip textured surface to ensure comfort and stability when holding the handle during transport.
[0016] The acrylic observation window is embedded in the upper surface of the cover through a slot. It has high light transmittance and is scratch-resistant. Operators can directly observe the placement status of the internal support through the observation window without having to frequently open the cover.
[0017] Preferably, the base frame adopts a U-shaped structure design, with its inner side fitting with the outer wall of the placement compartment with a clearance, and limit holes are respectively opened on both sides of the upper end face of the base frame.
[0018] In the design, the sliding adjustment and precise positioning of the limiting components are achieved through the U-shaped structure design of the base frame, clearance fit and limiting holes.
[0019] The inner side of the U-shaped base frame forms a wrap-around structure with the outer wall of the placement compartment, which enhances the guiding stability of the limiting components when they slide.
[0020] The clearance fit between the base frame and the placement compartment ensures that the limiting component can slide smoothly along the second groove while avoiding excessive shaking;
[0021] Limiting holes are located on both sides of the upper surface of the base frame, precisely corresponding to the sliding rods of the positioning component, enabling the limiting component to be quickly aligned and locked.
[0022] Preferably, both limiting plates adopt a triangular structure design, and the limiting plate cooperates with the first groove to achieve limiting by the vertical edge of the limiting plate contacting the side of the bracket.
[0023] In the design, the three-dimensional limiting and automatic limiting functions of the bracket are realized by the cooperation of the triangular limiting plate and the first groove.
[0024] The vertical side of the triangular limiting plate is in close contact with the side of the bracket, effectively restraining the lateral displacement of the bracket;
[0025] The beveled design of the limiting plate provides a guiding function. When the bracket is placed, the bevel can guide the bracket to slide into the first groove, ensuring accurate positioning of the bracket.
[0026] The synergistic effect of the limiting plate and the first groove enables the bracket to provide stable support in the vertical direction and limit displacement in the horizontal direction.
[0027] Preferably, slide rods are fixedly installed on both sides of the upper surface of the base plate, and the top of the slide rods has screw holes that pass through the limiting holes. A positioning bolt is threaded onto the top of the slide rods through the screw holes.
[0028] In the design, the elastic buffer function of the limiting component is achieved through the combination of the base plate, slide bar, connecting spring and positioning bolt.
[0029] The connecting spring is elastically installed between the base plate and the base frame to absorb vibration energy during transportation and avoid rigid collision between the limit plate and the bracket.
[0030] The positioning bolts are connected to the threaded holes at the top of the slide rod to lock the base frame at the target height, ensuring the structural stability of the limit assembly in the storage state.
[0031] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0032] This invention forms a stable support system by setting a first groove that fits into the movable placement of the bracket, combined with a U-shaped base frame and a gap-wrapping structure between the base frame and the placement chamber. The bracket's two ends are embedded in the first groove to ensure no horizontal displacement; the inner side of the base frame of the limiting component fits with the outer wall of the placement chamber, enhancing the guiding stability during sliding and preventing the bracket from falling off or tipping over when the device tilts or is impacted.
[0033] This invention achieves three-dimensional positioning and dynamic shock resistance by setting a triangular limiting plate that contacts the vertical side of the support, combined with the elastic buffer of the connecting spring. The inclined side design of the triangular limiting plate guides the sliding placement of the support, while the vertical side restricts lateral displacement; the connecting spring absorbs energy during transportation vibrations, avoiding structural damage caused by rigid collisions between the limiting plate and the support, and ensuring that the paper roll remains stable at all times.

[0039] 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.
[0040] Example 1
[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: a paper roll finished product storage device, including a placement compartment 1, a support 3 movably placed in the placement compartment 1, a cover 2 rotatably installed on the top of the placement compartment 1 via a hinge, a first groove 11 is provided on the upper end surface of the placement compartment 1, a second groove 12 is provided on the placement compartment 1 at the front end of the first groove 11, and a limiting component 4 is movably installed in the second groove 12.
[0042] The limiting component 4 includes a base frame 41, with a limiting plate 42 fixedly installed inside the base frame 41. The two limiting plates 42 are slidably installed in the second groove 12 respectively, and a positioning component 5 is movably installed at the bottom of the limiting component 4.
[0043] The positioning component 5 includes a base plate 51, on which a connecting spring 53 is elastically mounted, and the top of the connecting spring 53 is elastically connected to the bottom of the base frame 41.
[0044] Specifically, by setting the first groove 11 to cooperate with the movable placement of the bracket 3, combined with the gap-wrapping structure between the U-shaped base frame 41 and the placement chamber 1, a stable support system is formed. The two ends of the bracket 3 are embedded in the first groove 11 to ensure that there is no horizontal displacement; the inner side of the base frame 41 of the limiting component 4 is gap-fitted with the outer wall of the placement chamber 1 to enhance the guiding stability during sliding and prevent the bracket 3 from falling off or tipping over when the device tilts or is impacted.
[0045] This invention achieves three-dimensional positioning and dynamic shock resistance by setting a triangular limiting plate 42 in contact with the vertical side of the support 3, combined with the elastic buffer of the connecting spring 53. The inclined side design of the triangular limiting plate 42 guides the sliding placement of the support 3, while the vertical side restricts lateral displacement; the connecting spring 53 absorbs energy during transportation vibrations, avoiding structural damage caused by rigid collision between the limiting plate 42 and the support 3, and ensuring that the paper roll remains stable at all times.
[0046] Example 2
[0047] To achieve horizontal and stable support for the paper roll and facilitate easy loading and unloading, such as Figure 1 and Figure 2 As shown, in this embodiment, a finished paper roll is wound on the support 3, and the two ends of the support 3 are respectively movably placed in the first groove 11.
[0048] In the design, by placing the two ends of the support 3 for winding the finished paper roll into the first groove 11 respectively, the horizontal and stable support of the paper roll and the convenient picking and putting function are realized.
[0049] The first groove 11 is designed to match the diameter of the support shaft of the bracket 3, ensuring that the bracket 3 is naturally aligned when placed, forming a stable support reference surface;
[0050] The movable placement method allows the bracket 3 to slide along the first groove 11, which facilitates quick loading and unloading of paper rolls, while avoiding the wear and tear caused to the bracket 3 by traditional fixed installation methods.
[0051] Furthermore, a handle 21 is fixedly installed on the cover 2, and an acrylic observation window is embedded in the upper surface of the cover 2.
[0052] In the design, by fixing the handle 21 to the cover 2 and embedding an acrylic observation window, the device can be easily transported and its storage status can be visualized and monitored.
[0053] The handle 21 features an ergonomic curve design and a non-slip textured surface to ensure comfort and stability when holding the handle during transport.
[0054] The acrylic observation window 22 is embedded into the upper surface of the cover 2 through a slot. It has high light transmittance and is scratch-resistant. Operators can directly view the placement status of the internal support 3 through the observation window 22 without having to frequently open the cover 2.
[0055] Example 3
[0056] To achieve the sliding adjustment and precise positioning of the limiting component 4, as well as the effective limiting and elastic buffering functions of the bracket 3, such as Figure 3 and Figure 4As shown, in this embodiment, the base frame 41 adopts a U-shaped structure design, with its inner side having a clearance fit with the outer wall of the placement compartment 1, and limit holes 411 are respectively opened on both sides of the upper end face of the base frame 41.
[0057] In the design, the sliding adjustment and precise positioning of the limiting component 4 are achieved through the U-shaped structure design of the base frame 41, the clearance fit and the limiting hole 411.
[0058] The inner side of the U-shaped base frame 41 forms a wrapping structure with the outer wall of the placement compartment 1, which enhances the guiding stability of the limiting component 4 when it slides.
[0059] The clearance fit between the base frame 41 and the placement compartment 1 ensures that the limiting component 4 can slide smoothly along the second groove 12 while avoiding excessive shaking;
[0060] Limiting holes 411 are provided on both sides of the upper end face of the base frame 41, and correspond precisely to the slide rod 52 of the positioning component 5, so as to realize the quick alignment and locking of the limiting component 4.
[0061] Furthermore, both limiting plates 42 adopt a triangular structure design. The limiting plate 42 cooperates with the first groove 11, and the limiting is achieved by the vertical side of the limiting plate 42 contacting the side of the bracket 3.
[0062] In the design, the three-dimensional limiting and automatic limiting functions of the bracket 3 are realized by the cooperation of the triangular limiting plate 42 and the first groove 11.
[0063] The vertical side of the triangular limiting plate 42 is in close contact with the side of the bracket 3, effectively restraining the lateral displacement of the bracket 3.
[0064] The beveled design of the limiting plate 42 provides a guiding function. When the bracket 3 is placed, the beveled edge can guide the bracket 3 to slide into the first groove 11, ensuring that the bracket 3 is accurately positioned.
[0065] The synergistic effect of the limiting plate 42 and the first groove 11 achieves stable support of the bracket 3 in the vertical direction and displacement restriction in the horizontal direction.
[0066] Furthermore, slide rods 52 are fixedly installed on both sides of the upper end face of the base plate 51. The top of the slide rod 52 has a screw hole and passes through the limiting hole 411. The top of the slide rod 52 is threaded with a positioning bolt 521 through the screw hole.
[0067] In the design, the elastic buffer function of the limiting component 4 is realized through the combination of the base plate 51, the slide rod 52, the connecting spring 53 and the positioning bolt 521.
[0068] The connecting spring 53 is elastically installed between the base plate 51 and the base frame 41 to absorb vibration energy during transportation and prevent rigid collision between the limiting plate 42 and the bracket 3.
[0069] The positioning bolt 521 connects to the threaded hole at the top of the slide bar 52 to lock the base frame 41 at the target height, ensuring the structural stability of the limit assembly 4 in the storage state.
[0070] When using this invention, the device must first be opened to facilitate the placement or removal of the bracket 3. Specifically, the operation involves holding the handle 21 on the cover 2 and flipping the cover 2 upwards using the hinge structure between the cover 2 and the main body of the device. During the flipping process, the cover 2 can rotate smoothly along the axis of the hinge until it reaches a horizontal position. At this point, the internal space of the placement compartment 1 will be fully exposed, facilitating subsequent operations.
[0071] Place the support 3, with the finished paper roll wound around it, into the device. During operation, align both ends of the support 3 with the first groove 11 on the upper surface of the placement compartment 1, and gently insert it. The design of the first groove 11 matches the shape of the support 3, providing initial positioning and support for the support 3.
[0072] Once the support 3 is placed in the first groove 11, the finished paper roll will be fixed by the three-point support structure formed by the limiting component 4 and the support 3. The limiting plate 42 in the limiting component 4 will automatically contact the support 3, and through its interaction with the support 3, a stable three-point support structure will be formed. This structure can effectively prevent the finished paper roll from rolling or shifting in the placement chamber 1, ensuring the stability of the paper roll in the device.
[0073] To remove bracket 3, the fixing effect of the limiting component 4 on bracket 3 must first be released. During operation, press down on the base frame 41 by hand; the base frame 41 will compress the connecting spring 53. The connecting spring 53 is mounted on the base plate 51, and its elasticity allows the limiting plate 42 to move up and down. When the base frame 41 is pressed, the connecting spring 53 is compressed, and the limiting plate 42 moves downward, thereby releasing the limiting effect on bracket 3. At this time, bracket 3 is no longer constrained by the three-point support structure and can slide smoothly out of the first groove 11, completing the removal operation.
[0074] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
