Description

Technical Field

[0001] The invention relates to the technical field of cardboard storage, and in particular to a storage rack capable of preventing cardboard from being deformed. Background Art

[0002] Cardboard is a widely used packaging material. In order to save storage space, cardboard is often stored in multiple layers. However, in the process of placing cardboard, continuously placing cardboard on multiple layers will cause the upper cardboard to squeeze the lower cardboard. Especially when the cardboard is stacked unevenly, the stack of multiple layers of cardboard will be tilted. When the multiple layers of cardboard are tilted, the pressure distribution of the multiple layers of cardboard will be uneven, resulting in permanent deformation of the compressed cardboard, which will affect the performance and appearance of the cardboard during use. If the deformation of the lower cardboard is too large, it will cause the overall collapse of the cardboard stack, resulting in damage to the cardboard. Summary of the invention

[0003] In order to overcome the shortcomings pointed out in the above background technology, the present invention provides a storage rack for preventing cardboard from being deformed.

[0004] The technical implementation scheme of the present invention is: a storage rack for preventing cardboard from deforming, comprising a plurality of support rods distributed circumferentially and all arranged on a base, the base being fixedly connected with a support member, the support member being composed of an elastic ring at an upper portion and a plurality of support legs at a lower portion, the support member being slidably connected with a support frame distributed circumferentially, an elastic block being fixedly connected between the support frame and the base, a pressure sensor being installed between the support frame and the base, the base being fixedly connected with first electrically-controlled push rods distributed circumferentially and the same in number as the support frames, the telescopic end of the first electrically-controlled push rod being fixedly connected with a rectangular plate, the rectangular plate being slidably connected to the adjacent support frame, the rectangular plate at the telescopic end of the first electrically-controlled push rod being used to squeeze the support member.

[0005] Further description: the outer ring of the upper surface of the elastic ring on the support member is square, the circumferentially distributed support frames are respectively located at different edges of the support member, and the rectangular plate on the telescopic end of the first electric control push rod is located at the lower part of the adjacent support frame.

[0006] Further description, the support rod is slidably connected to an electromagnetic slider, the electromagnetic slider is fixedly connected to a connecting rod, the connecting rod is fixedly connected to a sliding block, and the sliding block is provided with a sliding plate.

[0007] Further description, the base is fixed with circumferentially distributed limit blocks and the number is the same as the number of the sliding plates, the limit blocks are used to guide adjacent sliding plates, the sliding blocks are slidably connected to the sliding plates, and elastic parts are fixed between the sliding blocks and the sliding plates.

[0008] It is further explained that a push plate is arranged on the sliding plate in a direction close to the support member, and the push plate is fixedly connected to a flexible plate.

[0009] It is further explained that the sliding plate is threadedly connected with symmetrically distributed threaded rods, and the threaded rods are rotationally connected to the adjacent pushing plates.

[0010] Further description, the sliding plate is installed with a second electric push rod, the telescopic end of the second electric push rod is fixedly connected to a sliding rod, the threaded rod is fixedly connected to a gear, the sliding rod is fixedly connected to a symmetrically distributed rack, and the rack is meshed with the gear of the adjacent threaded rod.

[0011] Further description, the thickness of the gear on the threaded rod is A, the thickness of the rack on the sliding rod is B, and A<B.

[0012] It is further explained that the sliding plate is fixedly connected to a shell, the shell is provided with a plurality of first holes distributed at intervals, and the shell is connected to an external air supply device.

[0013] Further description, the shell is installed with a motor, and the shell is rotatably connected with symmetrically distributed pulleys, the output shaft of the motor passes through the adjacent shell and is fixedly connected to the adjacent pulley, the pulleys symmetrically distributed in the shell are jointly wrapped with a shielding belt, the shielding belt is provided with a second hole, and the second hole is used to connect the adjacent first hole.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention supports the cardboard stack through the support member and the support frame. When the cardboard is unevenly placed, resulting in uneven pressure on various parts of the support member, the first circumferentially distributed electric push rod is used to adjust the deformation direction of the support member at various circumferential locations to control the inclination direction of the cardboard and reduce the degree of inclination of the cardboard, thereby ensuring that the cardboard is placed flat, thereby reducing the probability of compression and deformation of the cardboard due to tilted placement, and even causing the cardboard stack to collapse, thereby ensuring the performance of the cardboard during use and the safety during storage.

[0015] 2. The cardboard is squeezed and aligned by making the sliding plates distributed in the circumferential direction move back and forth horizontally respectively, so as to ensure that the cardboard is placed neatly. In the process of squeezing and aligning the cardboard by the sliding plates, the flexible plates rub the multi-layer cardboard upwards, so that gaps are generated between the multi-layer cardboards, so as to reduce the friction resistance generated when the multi-layer cardboards move relative to each other, improve the efficiency of cardboard alignment, and thus reduce the probability of compression deformation during the alignment of the cardboard. The push plate is driven to move by the rotation of the threaded rod, and the push plate drives the flexible plate to move, so as to adjust the distance between the flexible plate and the support, so as to squeeze and align cardboards of different sizes.

[0016] 3. The air flow is discharged to the second hole through the first hole. During the process of placing the cardboard, each layer of the multi-layer cardboard is blown from bottom to top, so that the air flow is blown into the space between adjacent cardboard sheets, reducing the frictional resistance generated by the contact between adjacent cardboard sheets, and thus reducing the difficulty of relative movement between adjacent cardboard sheets.

[0020] Embodiment 1

[0021] This embodiment discloses a storage rack for preventing cardboard from deforming, which is used to reduce the probability of deformation of the cardboard during the placement process.

[0022] As Figures 1-4As shown, the storage rack for preventing cardboard deformation includes four support rods 2 that are circumferentially distributed and are all arranged on the base 1. The base 1 is provided with a control terminal not shown in the figure. The base 1 is fixedly connected with a support member 3. The support member 3 is composed of an upper elastic ring and four lower support legs. The outer ring of the upper surface of the elastic ring on the support member 3 is square. Four circumferentially distributed support frames 4 are slidably connected to the support member 3. The four circumferentially distributed support frames 4 are respectively located at different edges of the support member 3. An elastic block 5 is fixedly connected between the support frame 4 and the base 1. Initially, the support member 3 and the elastic block 5 are not compressed. When the cardboard is placed on the support member 3 and the support frame 4, the elastic ring of the support member 3 is compressed and deformed. The support frame 4 moves downward and squeezes the elastic block 5. The elastic block 5 is compressed and deformed. A pressure sensor 6 is installed between the support frame 4 and the base 1. The pressure sensor 6 is electrically connected to the control terminal. The base 1 is fixedly connected with four first electric control push rods 7 that are circumferentially distributed and have the same number as the support frames 4. The first electric control push rods 7 are electrically connected to the control terminal. The telescopic end of the first electric control push rod 7 is fixedly connected with a rectangular plate. This rectangular plate is slidably connected to the adjacent support frame 4. The rectangular plate at the telescopic end of the first electric control push rod 7 is located below the adjacent support frame 4. The rectangular plate at the telescopic end of the first electric control push rod 7 is used to squeeze the elastic ring of the support member 3. When the cardboard is unevenly placed, resulting in uneven pressure on the four edges of the elastic block 5, the control terminal controls the telescopic end of the first electric control push rod 7 to move. Taking the example that the cardboard tilts forward, causing the front edge of the elastic ring of the support member 3 to be more pressured and the rear edge to be less pressured, the telescopic end of the front first electric control push rod 7 extends, and the telescopic end of the rear first electric control push rod 7 contracts. The telescopic end of the front first electric control push rod 7 extends and squeezes the front side of the elastic ring on the support member 3 through the rectangular plate, causing the front side of the elastic ring on the support member 3 to be compressed and deformed. The telescopic end of the rear first electric control push rod 7 drives the rectangular plate to move downward. The front side of the elastic ring on the support member 3 deforms upward and the rear side deforms downward, adjusting the position of the center of gravity of the cardboard stack to reduce the degree of downward tilt of the front side of the cardboard stack.

[0023] As Figure 2 , Figure 3 and Figure 5 shown, two electromagnetic sliders 8 that are both electrically connected to the control terminal are slidably connected to the support rod 2. Two electromagnetic sliders 8 on the same side of the same-side support rod 2 are jointly fixedly connected with a connecting rod 9. The connecting rod 9 is fixedly connected with a sliding block 10. The sliding block 10 is provided with a sliding plate 11. During the process of placing the cardboard, the electromagnetic slider 8 drives the adjacent sliding block 10 to reciprocate through the adjacent connecting rod 9. The sliding block 10 drives the adjacent sliding plate 11 to reciprocate. The reciprocating movement of the sliding plate 11 pushes the cardboard, improving the uniformity of placing multiple layers of cardboard. And when the left and right two sliding plates 11 move towards each other, the front and rear two sliding plates 11 move away from each other. When the left and right two sliding plates 11 move away from each other, the front and rear two sliding plates 11 move towards each other.

[0024] The specific working principle is as follows: When an operator needs to use this device to store cardboard, the operator first places several pieces of cardboard in multiple batches (each batch consists of multiple pieces) on the elastic ring of the support member 3. When placing multiple layers of cardboard on the elastic ring of the support member 3 and the support frame 4, the elastic ring of the support member 3 is deformed by the extrusion of the cardboard. At the same time, the support frame 4 moves downward under the extrusion of the cardboard and squeezes the elastic block 5 and the pressure sensor 6. The elastic block 5 is deformed under pressure, buffering the cardboard in the lower layer and reducing the probability of the cardboard in the lower layer being deformed under pressure.

[0025] During the process of placing the cardboard, if the cardboard is unevenly placed, resulting in uneven pressure on the four edges of the elastic ring on the support member 3, the pressures received by the four pressure sensors 6 are different. Taking the cardboard tilting forward, causing the front edge of the elastic ring on the support member 3 to be under greater pressure and the rear edge to be under less pressure as an example, at this time, the control terminal controls the telescopic end of the first electric push rod 7 to move. The telescopic end of the front first electric push rod 7 extends, and the telescopic end of the rear first electric push rod 7 contracts. The telescopic end of the front first electric push rod 7 extends and squeezes the front side of the elastic ring on the support member 3 through the rectangular plate, causing the front side of the elastic ring on the support member 3 to be deformed under pressure. The telescopic end of the rear first electric push rod 7 drives the rectangular plate to move downward, causing the front side of the elastic ring on the support member 3 to deform upward and the rear side to deform downward, adjusting the position of the center of gravity of the cardboard stack to reduce the degree of the front side of the cardboard stack tilting downward, thereby ensuring the flatness of the cardboard placement and further reducing the probability of the cardboard being deformed under pressure due to tilting placement.

[0026] During the process of placing the cardboard, the operator turns on all the electromagnetic sliders 8 through the control terminal. The electromagnetic sliders 8 drive the sliding block 10 to slide horizontally through the connecting rod 9. The sliding block 10 drives the adjacent sliding plates 11 to reciprocate. The sliding plates 11 reciprocate to push the cardboard. And when the left and right sliding plates 11 move towards each other, the front and rear sliding plates 11 move away from each other. When the left and right sliding plates 11 move away from each other, the front and rear sliding plates 11 move towards each other, so that the four sliding plates 11 alternately squeeze and align the cardboard to ensure the uniformity of the cardboard placement.

[0027] When the cardboard placement is completed, the electromagnetic sliders 8 drive the sliding block 10 to slide horizontally through the connecting rod 9. The sliding block 10 drives the adjacent sliding plates 11 to move, and the sliding plates 11 press the cardboard, binding the four sides of the multiple layers of cardboard to reduce the probability of the lower layer of cardboard being deformed under pressure due to the tilting of the multiple layers of cardboard and reducing the probability of the multiple layers of cardboard tilting and collapsing.

[0028] After the sliding plate 11 presses the cardboard, the control terminal controls the telescopic ends of all the first electric control push rods 7 to extend. The telescopic ends of the first electric control push rods 7 squeeze the elastic rings of the support member 3 through the rectangular plate, causing the elastic rings of the support member 3 to be deformed under pressure, and the support member 3 supports the multi-layer cardboard. During the long-term storage of the cardboard, if the cardboard absorbs moisture and deforms, resulting in the inclination of its stack body, taking the front side of the cardboard stack body tilting downward as an example, the pressure on the front side pressure sensor 6 increases. The control terminal controls the telescopic ends of the first electric control push rods 7 at the rear side to contract and drive their rectangular plates to move downward, causing the rear sides of the elastic rings on the support member 3 to rebound, and the rear sides of the elastic rings on the support member 3 to deform downward, causing the cardboard to tilt slightly backward, automatically straightening the cardboard to reduce the probability of the multi-layer cardboard tilting or even collapsing.

[0029] When the cardboard needs to be used, the operator controls the movement of all the electromagnetic sliders 8 through the control terminal. The electromagnetic sliders 8 drive the sliding blocks 10 to slide horizontally through the connecting rods 9. The sliding blocks 10 drive the adjacent sliding plates 11 to move, so that the sliding plates 11 no longer press the cardboard. The operator takes away the cardboard, so that the upper sides of the support member 3 and the support frame 4 are no longer under pressure. Then the operator controls the telescopic ends of the first electric control push rods 7 to contract and reset through the control terminal. The telescopic ends of the first electric control push rods 7 no longer squeeze the support member 3 through the rectangular plate, and the elastic rings and elastic blocks 5 of the support member 3 rebound and reset. Finally, the operator turns off the first electric control push rods 7 and the electromagnetic sliders 8 through the control terminal.

[0030] Embodiment 2

[0031] This embodiment discloses a storage rack for preventing cardboard deformation, which is further improved on the basis of Embodiment 1.

[0032] As Figure 5 shown in Figure 6 shown, the base 1 is fixedly connected with limit blocks 12 that are circumferentially distributed and have the same number as the sliding plates 11. One side of the upper part of the limit block 12 away from the support member 3 is provided with an inclined surface. During the reciprocating sliding of the sliding plate 11, the limit block 12 guides the adjacent sliding plate 11, so that the sliding plate 11 moves along the inclined surface of the adjacent limit block 12. When the sliding plate 11 moves towards the support member 3, the sliding plate 11 moves upward relative to the sliding block 10. When the sliding plate 11 moves away from the support member 3, the sliding plate 11 moves downward relative to the sliding block 10. The sliding block 10 is slidably connected with the sliding plate 11, and an elastic member is fixedly connected between the sliding block 10 and the sliding plate 11. The elastic member is a compression spring. When the sliding plate 11 moves upward relative to the sliding block 10, the elastic member is compressed and stores energy. When the sliding plate 11 moves downward relative to the sliding block 10, the elastic member rebounds and resets.

[0033] As Figure 5 shown in Figure 6As shown in the figure, a push plate 13 is arranged on the sliding plate 11 in the direction close to the support 3. A flexible plate 14 is fixedly connected to the push plate 13. The flexible plate 14 is used to extrude the multi-layer cardboard, reducing the probability of the edge of the cardboard box being damaged. When the sliding plate 11 moves towards the multi-layer cardboard on the support 3, the sliding plate 11 drives the flexible plate 14 to extrude the multi-layer cardboard through the push plate 13. The flexible plate 14 extrudes and aligns the cardboard. At this time, the sliding plate 11 is guided by the limit block 12 and moves upward. The sliding plate 11 drives the flexible plate 14 to move upward through the push plate 13. During the process of extruding and aligning the cardboard, the flexible plate 14 drives the multi-layer cardboard upward, creating a gap between the multi-layer cardboard, so as to reduce the frictional resistance generated when the multi-layer cardboard moves relative to each other, improve the efficiency of aligning the cardboard, and thus reduce the probability of the cardboard being deformed under pressure during the alignment process.

[0034] Embodiment 3

[0035] This embodiment discloses a storage rack for preventing cardboard deformation, which is further improved on the basis of Embodiment 2.

[0036] As Figure 6 And Figure 7 As shown in the figure, the sliding plate 11 is threadedly connected with threaded rods 15 symmetrically distributed up and down. The threaded rods 15 are rotatably connected to the adjacent push plates 13. By rotating the threaded rods 15, the threaded rods 15 drive the adjacent push plates 13 to move.

[0037] As Figure 6 And Figure 7 As shown in the figure, the sliding plate 11 is equipped with a second electric push rod 16 electrically connected to the control terminal. The telescopic end of the second electric push rod 16 is fixedly connected with a sliding rod 17. A gear is fixedly connected to the threaded rod 15. Two racks symmetrically distributed up and down are fixedly connected to the sliding rod 17. The racks are engaged with the gears of the adjacent threaded rods 15. When it is necessary to adjust the position of the flexible plate 14, the control terminal controls the telescopic end of the second electric push rod 16 to move. The telescopic end of the second electric push rod 16 drives the two racks to move through the sliding rod 17, causing the adjacent two gears to rotate and respectively drive the adjacent threaded rods 15 to rotate. The two threaded rods 15 jointly drive the adjacent flexible plate 14 to move through the push plate 13. The thickness of the gear on the threaded rod 15 is A, and the thickness of the rack on the sliding rod 17 is B, where A < B. When the gear on the threaded rod 15 moves horizontally, the gear and the rack are kept engaged. When storing cardboard stacks of different sizes, the operator controls the telescopic end of the second electric push rod 16 through the control terminal. The telescopic end of the second electric push rod 16 drives the two racks to move through the sliding rod 17, causing the two gears to respectively drive the adjacent threaded rods 15 to rotate. The threaded rods 15 rotate and move relative to the adjacent sliding plate 11. The threaded rods 15 drive the push plates 13 to move, and the push plates 13 drive the flexible plates 14 to move, so as to adjust the initial distance between the flexible plates 14 and the support 3 to extrude and align different-sized cardboard.

[0038] Example 4

[0039] This embodiment discloses a storage rack for preventing cardboard deformation, which is further improved on the basis of Embodiment 3.

[0040] As Figure 2 、 Figure 5 and Figure 7 shown, a sliding plate 11 is fixedly connected with a housing 18. The housing 18 is provided with a plurality of first holes 1801 distributed at intervals. The housing 18 is communicated with an external air supply device, and the external air supply device is electrically connected with a control terminal.

[0041] As Figure 7 and Figure 8 shown, a motor 19 electrically connected with the control terminal is installed on the housing 18. Two pulleys 20 symmetrically distributed up and down are rotatably connected in the housing 18. An output shaft of the motor 19 passes through an adjacent housing 18 and is fixedly connected with an adjacent pulley 20. The pulleys 20 symmetrically distributed in the housing 18 jointly wind a shielding belt 21. A connection part between the housing 18 and the external air supply device is located inside the shielding belt 21. The shielding belt 21 is provided with second holes 2101 for communicating adjacent first holes 1801. The control terminal controls the output shaft of the motor 19 to rotate. The output shaft of the motor 19 drives the adjacent pulleys 20 to rotate, so that the shielding belt 21 rotates around the adjacent two pulleys 20. The shielding belt 21 drives the second holes 2101 thereon to rotate, so that the second holes 2101 are aligned and communicated with a plurality of first holes 1801 on the adjacent housing 18 in sequence from bottom to top.

[0042] The specific working principle is as follows: During the storage of cardboard, an operator turns on the external air supply device through the control terminal. The external air supply device conveys air flow into the housing 18. The air flow is discharged through the second holes 2101 and the first holes 1801 to blow the cardboard, so as to keep the dryness between multiple layers of cardboard and reduce the probability of mildew during the storage of cardboard.

[0043] During the process of placing the cardboard, an external air supply device conveys air flow into the housing 18, enabling the air flow to enter the shielding belt 21. An operator turns on the motor 19 through a control terminal. The output shaft of the motor 19 drives the adjacent pulley 20 to rotate. The pulley 20 drives the lower pulley 20 to rotate through the shielding belt 21. The shielding belt 21 drives the second holes 2101 thereon to rotate, causing the second holes 2101 to be aligned and communicated with a plurality of first holes 1801 on the adjacent housing 18 in sequence from bottom to top. The air flow first discharges through the lowermost first hole 1801 and the second hole 2101. Along with the stacking of the cardboard layer by layer, the air flow discharges from the plurality of first holes 1801 to the second holes 2101 from bottom to top, blowing the cardboard stack from bottom to top, so that the air flow is blown into the space between two adjacent cardboard sheets, reducing the frictional resistance generated by the contact between two adjacent cardboard sheets, thereby reducing the difficulty of relative movement between the two cardboard sheets, and further improving the efficiency of aligning the cardboard during placement.

[0044] In summary, the invention includes but is not limited to the above embodiments. Any equivalent replacement or partial improvement made under the spirit and principle of the present invention will be regarded as within the protection scope of the present invention.
