A PVC wood-plastic board pressure-proof stacking rack

Abstract

The present invention discloses a PVC wood-plastic board pressure-proof stacking rack, comprising a fixed bottom plate, a support frame plate, a limiting cover plate and an elastic stacking unit. The first support plate, the second support plate and the third support plate are located in the middle position of the support frame plate before the wood-plastic board is placed, so that the first support plate located at the bottom is not too low and the third support plate located at the upper layer is not the highest. Therefore, when placing the wood-plastic board on the first support plate, the bending angle is lower, and when placing the wood-plastic board on the third support plate, there is no need to lift it too much, so that the labor intensity during placement is low. Moreover, under the separated support of the first support plate, the second support plate and the third support plate, the number of wood-plastic boards placed on each layer is not large, so that the wood-plastic boards located at the bottom layer are not subjected to much pressure and will not be deformed. The boards are kept aligned under the flush contact of the support frame plate, thereby solving the problems of instability of the existing stacking rack when the number of boards is large and compression deformation and damage of the wood-plastic boards at the bottom layer.

Description

Technical Field

[0001] The invention relates to the field of PVC plate processing, in particular to a PVC wood-plastic plate pressure-proof stacking rack. Background Art

[0002] Wood plastic board is a high-tech green and environmentally friendly new composite decorative material mainly made of wood as the base material, thermoplastic polymer materials (plastics) and processing aids, which are mixed evenly and then heated and extruded by mold equipment. Wood plastic board combines the advantages of solid wood and plastic, making it have more functions.

[0003] The Chinese invention patent with publication number CN114084684A disclosed a post-surface treatment stacking device for wood-plastic flooring on February 25, 2022. The top of the work plate is fixedly connected to a work frame, and a transfer device for transporting the wood-plastic flooring is provided between the top of the work plate and the interior of the work frame. A collection device for stacking and collecting the wood-plastic flooring is fixedly installed on the top of the work plate and on one side of the transfer device. A leveling device for leveling the wood-plastic flooring is provided on one side of the work frame and at positions corresponding to the transfer device and the collection device. The setting of the leveling device of the present invention can cause the connecting plate to squeeze the first connecting plate when the transfer device drives the suction cup and the wood-plastic flooring to operate, so that the squeezing rod can be used to rotate along the second connecting plate, so that one end of the second connecting plate can push the second telescopic rod and the second connecting plate to move, thereby leveling the wood-plastic flooring placed on top of the stacking plate.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: although the automated transfer and stacking of wood-plastic panels is achieved, the transferred wood-plastic panels are stacked together in an overlapping manner, which causes squeezing and deformation of the wood-plastic panels on the lower layer when the number is large, and is not suitable for long-term storage of wood-plastic panels. At the same time, when the width of the wood-plastic panels is less than 20 cm, the panels are easily overturned when stacked too high, which may cause accidents during use. Summary of the Invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a PVC wood-plastic board pressure-proof stacking rack.

[0006] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0007] The technical solution adopted by the present invention to solve its technical problems is: the PVC wood-plastic board pressure-proof stacking rack described in the present invention comprises a fixed base plate, a supporting frame plate, a limiting cover plate and an elastic stacking unit; the upper surface of the fixed base plate is fixedly connected to the supporting frame plate; the upper end of the supporting frame plate is fixedly connected to the limiting cover plate; an elastic stacking unit is provided in the supporting frame plate; the elastic stacking unit comprises a first slider, a second slider and a third slider; the upper and lower ends of the first slider are respectively fixedly connected to the second spring and the first spring; the upper end of the second spring is fixedly connected to the second slider; the upper end of the second slider is fixedly connected to the third spring; the upper end of the third spring is fixedly connected to the third slider; the upper end of the third slider is fixedly connected to the fourth spring; the first slider, the second slider and the third slider are slidably inserted in the supporting frame plate; the first slider, the second slider and the third slider are respectively fixedly connected to the first support plate, the second support plate and the third support plate.

[0008] Furthermore, two ends of the first support plate, the second support plate and the third support plate are symmetrically pin-connected with a bottom support plate; and the upper surface of the bottom support plate is pin-connected with an extension plate.

[0009] Furthermore, the lower surface of the fixed base plate is symmetrically provided with grooves; inclined blocks are symmetrically fixed in the grooves; a sliding groove is provided in the inclined block; sliding grooves are provided on the fixed base plate and the inclined block; a slider plate is slidably inserted in the sliding grooves; a center plate is sleeved on the slider plate; an extension plate is fixed to the lower surface of the center plate; rollers are symmetrically fixed to the lower surface of the extension plate; a baffle is slidably inserted in the sliding grooves; a threaded shaft is rotatably connected to the baffle; the threaded shaft is threadedly inserted on the fixed base plate; and a rotating shaft is inserted into the hole at the end of the threaded shaft.

[0010] Furthermore, a traction rope is fixedly connected between the first sliding block and the center plate; and a rope hole corresponding to the traction rope is opened on the fixed base plate.

[0011] Furthermore, the length of the first spring is greater than that of the second spring, the third spring and the fourth spring; the length and elastic force of the second spring and the third spring are the same; the length and elastic force of the fourth spring are less than that of the second spring and the third spring.

[0012] Furthermore, the elastic force of the first spring is greater than the elastic force of the second spring, the third spring and the fourth spring.

[0013] The present invention provides a PVC wood-plastic board pressure-resistant stacking rack, which has the following beneficial effects:

[0014] 1. The present invention uses a combination of different elastic forces and lengths of the first, second, third and fourth springs to ensure that the fixed first, second and third support plates are in the middle of the support frame before the wood-plastic board is placed, so that the first support plate at the bottom is not too low and the third support plate at the upper layer is not the highest. Therefore, when placing the wood-plastic board on the first support plate, the bending angle is smaller, and when placing the wood-plastic board on the third support plate, there is no need to lift it too much, so that the labor intensity during placement is low. Moreover, under the separate support of the first, second and third support plates, the number of wood-plastic boards placed on each layer is not large, so that the wood-plastic board at the bottom layer is not subjected to much pressure and will not be deformed. In addition, the wood-plastic board at the bottom layer is kept aligned under the flush contact of the support frame, thereby solving the problems of instability of the existing stacking rack when a large number of boards are stacked and deformation and damage of the wood-plastic boards at the bottom layer due to pressure.

[0015] 2. The present invention aligns the upper surface of the extension plate with the rotation connection through the bottom support plate, so that when placing a longer PVC wood-plastic board on the first support plate, the second support plate and the third support plate, the extension plate can be rotated for support. At the same time, when placing a wood-plastic board with a larger width, it can be placed on the folded first support plate, the second support plate, the third support plate and the extension plate, thereby increasing the contact area and being more stable. This solves the problem that the existing stacking device has a limited support area and cannot expand the support area, resulting in the inability to stack wood-plastic boards of different shapes.

[0025] The two ends of the first support plate 13, the second support plate 12 and the third support plate 11 are symmetrically pin-connected with a bottom support plate 14; the upper surface of the bottom support plate 14 is pin-connected with an extension plate 15; when working, the bottom support plate 14 is used to align the upper surface of the extension plate 15 for rotation connection, so that when a longer PVC wood-plastic board is placed on the first support plate 13, the second support plate 12 and the third support plate 11, the extension plate 15 can be rotated for support. At the same time, when placing a wood-plastic board with a larger width, it can be placed on the folded first support plate 13, the second support plate 12, the third support plate 11 and the extension plate 15, thereby increasing the contact area and being more stable, solving the problem that the support area of ​​the existing stacking device is limited and the support area cannot be expanded, resulting in the inability to stack wood-plastic boards of different shapes.

[0026] The lower surface of the fixed base plate 1 is symmetrically provided with grooves 16; tilting blocks 17 are symmetrically fixed in the grooves 16; a sliding groove 18 is provided in the tilting block 17; a sliding groove 19 is provided on the fixed base plate 1 and the tilting block 17; a slider plate 20 is slidably inserted in the sliding groove 19; a center plate 21 is sleeved on the slider plate 20; an extension plate 22 is fixed to the lower surface of the center plate 21; rollers 23 are symmetrically fixed to the lower surface of the extension plate 22; a baffle plate 24 is slidably inserted in the sliding groove 18; a threaded shaft 25 is rotatably connected to the baffle plate 24; the threaded shaft 25 is threadedly inserted on the fixed base plate 1; The end opening of the threaded shaft 25 is plugged with a rotating shaft 26; when working, the threaded shaft 25 is driven to rotate by holding the rotating shaft 26, thereby pushing the baffle 24 to continuously contact and squeeze the center plate 21, and move along the slide groove 19, so that the roller 23 fixed on the center plate 21 is in contact with the ground, so that the stacking rack can be moved, which is convenient for moving after stacking the wood-plastic panels, and when it does not need to be moved, the fixed bottom plate 1 is in stable contact with the ground, stably supporting the placed PVC wood-plastic panels, and solving the problem that the existing stacking rack is unstable and easy to move and shake after fixing a large number of wood-plastic panels after installing universal wheels, resulting in tipping.

[0027] A traction rope 27 is fixedly connected between the first slider 5 and the center plate 21; a rope hole 28 is opened on the fixed base plate 1 corresponding to the traction rope 27; when working, the first slider 5 and the center plate 21 are connected by the traction rope 27, so that when the first support plate 13 on the first slider 5 has no PVC wood-plastic board placed on it, the center plate 21 is lifted up under the elastic force of the first spring 4, so that the roller 23 moves with the slider plate 20, the center plate 21 and the extension plate 22 in the slide groove 19 and contacts the ground, thereby realizing the movement of the stacking rack by rolling friction, which solves the problem that the existing stacking rack is unstable and easy to move and shake after fixing a large number of wood-plastic boards after installing universal wheels, resulting in tipping.

[0028] The length of the first spring 4 is greater than the length of the second spring 6, the third spring 8 and the fourth spring 10; the length and elastic force of the second spring 6 and the third spring 8 are the same; the length and elastic force of the fourth spring 10 are less than the length and elastic force of the second spring 6 and the third spring 8; when working, the length of the first spring 4 is greater than the length of the second spring 6, the third spring 8 and the fourth spring 10, so that the first support plate 13, the second support plate 12 and the third support plate 11 are in the middle position of the support frame plate 2 when the wood-plastic board is not stacked, and then when stacking, it is possible to stack on the first support plate 13 without bending over, then stack on the second support plate 12, and finally stack on the third support plate 11 During stacking, there is no need to bend over at a large angle or lift the wood-plastic boards to be stacked on the third support plate 11 located at a high position, and then a limited number of wood-plastic boards are stacked on the first support plate 13, the second support plate 12 and the third support plate 11, and all lean against the support frame plate 2 to keep them flush. With the support of the symmetrical extension plate 15, the number of rows of stacked wood-plastic boards is expanded, so that more PVC wood-plastic boards can be stacked on the first support plate 13, the second support plate 12 and the third support plate 11 of each layer, which solves the problem that the existing device for stacking wood-plastic boards cannot stack wood-plastic boards of a higher number, and the stacking is not neat and stable, and the wood-plastic board at the bottom is deformed due to the large force, so that the long-term stacking remains stable.

[0029] The elastic force of the first spring 4 is greater than the elastic force of the second spring 6, the third spring 8 and the fourth spring 10. During operation, the elastic force of the first spring 4 is greater than the elastic force of the second spring 6, the third spring 8 and the fourth spring 10, so that when the PVC wood-plastic board is not placed, the first support plate 13 is pushed away from the ground by the elastic force of the first spring 4, thereby facilitating the stacking of wood-plastic boards on the lowest first support plate 13, eliminating the need to bend over to carry the wood-plastic boards, making stacking of wood-plastic boards more convenient, and solving the problem that the existing stacking device has a low stacking position at the beginning of stacking, requiring manual bending over for stacking, resulting in low stacking efficiency and high labor intensity.

[0030] With the above solution, when the present invention is in use, the first spring 4, the second spring 6, the third spring 8 and the fourth spring 10 are combined with different elastic forces and lengths, so that the fixed first support plate 13, the second support plate 12 and the third support plate 11 are in the middle position of the support frame plate 2 before the wood-plastic board is placed, so that the first support plate 13 located at the bottom is not too low, and the third support plate 11 located at the upper level is not the highest, so that when placing the wood-plastic board on the first support plate 13, the bending amplitude is lower, and when placing the wood-plastic board on the third support plate 11, there is no need to lift it too much, so that the labor intensity during placement is low, and the first support plate 13, the second support plate 12 and the third support plate are not too low. Under the support of the partition 11, the number of wood plastic boards placed on each layer is not large, so that the wood plastic boards at the bottom layer are not subjected to much pressure and will not be deformed, and they are kept aligned under the flush contact of the support frame plate 2, which solves the problem of instability when the existing stacking rack is stacked with a large number of boards and the problem of the bottom wood plastic boards being deformed and damaged by pressure; the rotation connection of the upper surface of the extension plate 15 is aligned by the bottom support plate 14, so that when a long PVC wood plastic board is placed on the first support plate 13, the second support plate 12 and the third support plate 11, the extension plate 15 can be rotated for support, and when a wood plastic board with a larger width is placed, it can be placed on the folded first support plate 13 and the third support plate 11. The second support plate 12, the third support plate 11 and the extension plate 15 are arranged on the second support plate 12, the third support plate 11 and the extension plate 15, thereby increasing the contact area and being more stable, solving the problem that the support area of ​​the existing stacking device is limited and the support area cannot be expanded, resulting in the inability to stack wood-plastic boards of different shapes; by holding the rotating shaft 26 and rotating it, the threaded shaft 25 is driven to rotate, thereby pushing the baffle 24 to continuously contact and squeeze with the center plate 21, and move along the slide 19, so that the roller 23 fixed on the center plate 21 is in contact with the ground, so that the stacking rack can be moved, which is convenient for moving after stacking the wood-plastic boards, and when it does not need to be moved, the fixed bottom plate 1 is in stable contact with the ground, stably supporting the placed PVC wood The traction rope 27 connects the first slider 5 and the center plate 21, so that when the first support plate 13 on the first slider 5 is not placed with the PVC wood-plastic board, the center plate 21 is lifted up under the elastic force of the first spring 4 to pull the center plate 21, so that the roller 23 moves with the slider plate 20, the center plate 21 and the extension plate 22 in the slide groove 19 and contacts the ground, thereby realizing the movement of the stacking rack by rolling friction, which solves the problem that the existing stacking rack is unstable and easy to move after a large number of wood-plastic boards are fixed after the universal wheels are installed, resulting in tilting.Because the length of the first spring 4 is greater than the length of the second spring 6, the third spring 8 and the fourth spring 10, the first support plate 13, the second support plate 12 and the third support plate 11 are in the middle position of the support frame plate 2 when the wood-plastic boards are not stacked. Then, when stacking, you do not need to bend over to stack them on the first support plate 13, then on the second support plate 12, and finally on the third support plate 11. There is no need to bend over at a large angle throughout the whole process, and there is no need to lift the wood-plastic boards to stack them on the third support plate 11 located at a high position. Then, a limited number of wood-plastic boards are stacked on the first support plate 13, the second support plate 12 and the third support plate 11, and all lean against the support frame plate 2 to keep them flush. With the support of the symmetrical extension plate 15, the number of rows of stacked wood-plastic boards is expanded, so that the first support plate 13, the second support plate 12 and the third support plate 11 of each layer can be stacked. The board 12 and the third support board 11 can stack more PVC wood-plastic boards, solving the problem that the existing device for stacking wood-plastic boards cannot stack higher layers of wood-plastic boards, and the stacking is not neat and stable, and the bottom wood-plastic board is subjected to great force and deformed, so that long-term stacking can be maintained stable; because the elastic force of the first spring 4 is greater than the elastic force of the second spring 6, the third spring 8 and the fourth spring 10, when no PVC wood-plastic boards are placed, the elastic force of the first spring 4 pushes the first support board 13 away from the ground, thereby facilitating the stacking of wood-plastic boards on the bottom first support board 13, eliminating the need to bend down to carry the wood-plastic boards, making stacking of wood-plastic boards more convenient, and solving the problem that the existing stacking device has a low stacking position at the beginning of stacking, requiring manual bending over to stack, resulting in low stacking efficiency and high labor intensity.
