Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of master batch storage, and particularly relates to a master batch self-maintenance storage method. BACKGROUND
[0002] As a functional additive material commonly used in the plastic processing process, master batch is usually stored and circulated in the form of bags.
[0003] However, in the multi-layer stacking storage process of bagged master batch, the lower bag body bears the vertical static pressure of the upper bag body for a long time, especially in the case of a large number of stacking layers, a large single bag mass or a long storage period, which can easily cause the compaction, plate formation and even local caking of master batch in the bag. The above-mentioned static pressure plate formation problem is particularly obvious in master batch with a high filler proportion, small particle size or high humidity sensitivity.
[0004] Once the master batch is caked in the bag, it often needs to be treated by artificial knocking, kneading or secondary crushing during the subsequent bag opening and feeding process. In addition, serious plate formation can also cause part of the master batch to be scrapped, increasing the production cost.
[0005] In view of the above problems, the following methods are usually used to improve the existing technology: first, regular restacking, the whole bag body is turned over or re-stacked by artificial or forklift to change the stress state, so as to relieve the long-term static pressure borne by the lower bag body; second, reducing the number of stacking layers, the pressure borne by the lower bag body is reduced by reducing the stacking height; third, improving the storage environment, such as reducing the environmental humidity or shortening the storage period.
[0006] However, the above-mentioned existing methods still have obvious deficiencies: the restacking operation depends on artificial or forklift operation, which is labor-intensive; reducing the number of stacking layers can significantly reduce the utilization rate of warehouse space; and the environmental control measures are often difficult to completely eliminate the plate formation problem caused by long-term static pressure, especially in the case of a long storage period, the effect is limited. SUMMARY
[0007] The purpose of the present application is to solve the problem of bagged master batch prone to plate formation in the background art, and a master batch self-maintenance storage method is proposed.
[0008] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:
[0009] A master batch self-maintenance storage method, comprising the following steps:
[0010] a1, first bagging master batch to form bagged master batch;
[0011] a2, a plurality of lifting plates capable of moving up and down are distributed on the pressure bearing platform along the length direction;
[0012] a3. Stack the bagged masterbatch on multiple lifting plates in an alternating manner;
[0013] a4. At regular intervals t, at least one lifting plate shall be raised and lowered at least once.
[0014] The self-maintenance storage method for masterbatch proposed in this invention has the following advantages: during the storage process, at least one lifting plate is periodically driven to rise and fall, so that the bagged masterbatch can generate periodic vertical displacement changes in the stacked state, thereby effectively avoiding the bagged masterbatch being in a fixed static pressure state for a long time during the storage period, and reducing the risk of the masterbatch being compacted and caking due to continuous static pressure inside the bag.

Detailed Implementation
[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
[0019] Reference Figs. 1-2 A self-maintaining storage method for masterbatch includes the following steps:
[0020] a1. First, the masterbatch is bagged to form bagged masterbatch 5;
[0021] a2. Several lifting plates 12 that can move up and down are distributed along the length of the pressure-bearing platform 11;
[0022] a3. Stack the bagged masterbatch 5 on multiple lifting plates 12 in an alternating manner;
[0023] a4. At regular intervals t, at least one lifting plate 12 is raised and lowered at least once. For example, t can be every half day, one day, or two days, with each lifting plate 12 raised and lowered 5-10 times or even more each time.
[0024] The masterbatch is bagged to form bagged masterbatch 5, storing the masterbatch in a relatively enclosed bag. Several vertically movable lifting plates 12 are distributed along the length of a pressure platform 11, creating multiple independently movable bearing areas. The bagged masterbatch 5 is stacked on the lifting plates 12 in an alternating manner, so that different vertical positions of the bagged masterbatch 5 are supported by different lifting plates 12. This results in multiple columns of bagged masterbatch 5 in the stack with different stress states in the vertical direction. During storage, at intervals t, the pressure is adjusted... At least one lifting plate 12 moves up and down relative to the pressure platform 11, thereby causing the bagged masterbatch 5 located on the lifting plate 12 to undergo periodic vertical displacement changes. During the above lifting process, some of the bagged masterbatch 5 moves vertically with the corresponding lifting plate 12, while the bagged masterbatch 5 at its adjacent position remains relatively stationary because it does not undergo synchronous lifting. This causes the bagged masterbatch 5 to form periodic relative displacement and force changes inside the stack, changing the masterbatch inside the bag from a state of single static pressure to a state of dynamic force, thereby changing the stacking form of the masterbatch inside the bag.
[0025] During storage, at least one lifting plate 12 is periodically driven to rise and fall, so that the bagged masterbatch 5 can generate periodic vertical displacement changes in the stacked state, thereby effectively avoiding the bagged masterbatch 5 being in a fixed static pressure state for a long time during the storage period, and reducing the risk of the masterbatch being compacted and caking due to continuous static pressure inside the bag.
[0026] Meanwhile, since the bagged masterbatch 5 is stacked in an alternating manner, the lifting and lowering movements of different lifting plates 12 can create staggered force changes inside the stack, which continuously disturbs the stacking state of the masterbatch inside the bag. This helps to maintain the looseness of the masterbatch, thereby achieving self-maintenance of the storage state of the bagged masterbatch without the need for stacking or reducing the stacking height. This reduces manual intervention, improves the utilization rate of storage space, and reduces the difficulty of subsequent bag opening and feeding processes.
[0027] refer to Fig. 2 The lifting plate 12 that needs to be lifted is positioned as the pre-lifting platform 4. The row of bagged masterbatch 5 directly above the pre-lifting platform 4 is defined as the lifting column 1. The two rows of bagged masterbatch 5 on both sides of the lifting column 1 are defined as the static pressure column 2. The row of bagged masterbatch 5 that is partially sandwiched between the static pressure column 2 and partially sandwiched between the lifting column 1 is defined as the semi-pressure column 3.
[0028] When the pre-lifting platform 4 is in its initial state, the lifting column 1, the static pressure column 2, and the semi-pressure column 3 together form a multi-layered staggered stacking structure, wherein the static pressure column 2 forms a continuous static pressure constraint on the corresponding part of the semi-pressure column 3 in the vertical direction.
[0029] When the pre-lifting platform 4 rises and falls within a predetermined time interval, the pre-lifting platform 4 drives the lifting column 1 above it to move vertically in sync. Since a part of the semi-pressure column 3 is adjacent to and in contact with the lifting column 1, this part of the semi-pressure column 3 moves vertically in sync with the lifting column 1, while the other part of the semi-pressure column 3 constrained by the static pressure column 2 remains relatively stationary.
[0030] During the above-mentioned movement, the semi-compression column 3 forms a relative displacement difference inside its bag body, thereby causing the semi-compression column 3 to undergo periodic bending deformation during the lifting and lowering process; as the pre-lifting platform 4 repeatedly rises and falls, this bending deformation is repeatedly generated in the semi-compression column 3, causing the masterbatch inside the bagged masterbatch 5 to change from a long-term static compacted state to a dynamic disturbed state.
[0031] The pre-lifting platform 4 periodically drives the lifting column 1 to reciprocate vertically, and the static pressure column 2 partially constrains the semi-pressure column 3, causing the semi-pressure column 3 to repeatedly bend and deform without stacking, thereby continuously changing the stress state and stacking shape of the masterbatch inside the bagged masterbatch 5.
[0032] This method can effectively avoid the problems of compaction, caking, or local clumping caused by continuous vertical static pressure during long-term multi-layer stacking of bagged masterbatch 5. Without reducing the number of stacking layers or increasing manual intervention, it can achieve self-maintenance and adjustment of the storage state of bagged masterbatch, and significantly improve the subsequent unpacking and feeding performance of bagged masterbatch.
[0033] To better fill the gaps, when the bagged masterbatch 5 in a3 is stacked, the bag in the length direction is defined as the long placement bag 7 and the bag in the width direction is defined as the wide placement bag 8. In the entire placement space, the placement gap at the end of the long placement bag 7 is filled by the wide placement bag 8; and / or, in the entire placement space, the bottom placement gap is filled by the pad plate 10.
[0034] A gap 6 is left between every two adjacent long stacking bags 7 along the length direction; the gap 6 is left between every two adjacent long stacking bags 7 along the length direction, so that the adjacent bagged masterbatch 5 are not completely attached to each other.
[0035] During the process of the pre-lifting platform 4 driving the lifting column 1 to rise or fall, the lifting column 1 generates vertical displacement. Due to the existence of the gap 6, there is a certain displacement margin between adjacent long placement bags 7, so that the bag body can undergo local deformation or relative displacement when the force changes, rather than being rigidly compressed as a whole.
[0036] The above settings can reduce the continuous surface contact pressure caused by the tight stacking of the bag masterbatch 5, making it easier for the bag to bend, loosen or slightly misalign during lifting and lowering, thereby promoting the change of the state of the masterbatch inside the bag.
[0037] In one implementation, the bagged masterbatch located in the middle is covered by three adjacent lifting plates, one of which is fully covered and the two side lifting plates are partially covered. When the three lifting plates move up and down, the three parts of a bagged masterbatch can be bent separately, which can better promote the disturbance of the masterbatch.
[0038] Vertical baffles 9 are installed on both sides of the pressure platform 11 to prevent the bags from tipping over. Through the limiting effect of the vertical baffles 9, the bagged masterbatch 5 is mainly bent and deformed during the lifting and lowering process, rather than being tilted over or laterally slipped, thereby ensuring the stability of the relative positional relationship between the lifting column 1 and the static pressure column 2 and the semi-pressure column 3.
[0039] All bagged masterbatch 5 distributed vertically within the placement space are defined as vertical masterbatch bags 17, and a lifting plate 12 is set directly below each vertical masterbatch bag 17. A through hole 16 is opened below each lifting plate 12 corresponding to the pressure platform 11, and a power lifting component 13 is set below the pressure platform 11 to drive the lifting plate 12 to rise and fall.
[0040] In one embodiment, all bagged masterbatch 5 distributed vertically within the placement space are defined as vertical masterbatch bags 17, and a lifting plate 12 is provided directly below each vertical masterbatch bag 17. A through hole 16 is provided below each lifting plate 12 corresponding to the pressure platform 11, and a powered lifting component 13 is provided below the pressure platform 11 and directly below each lifting plate 12. By controlling each powered lifting component 13, different lifting plates 12 perform rising and falling movements according to a predetermined sequence or interval, thereby realizing the alternating rising and falling of different vertical masterbatch bags 17.
[0041] A power lifting component 13 is installed below the pressure platform 11. The power lifting component 13 is preferably a hydraulic cylinder or an electric push rod. A power lifting component 13 is installed below each lifting plate 12, and each power lifting component 13 is electrically connected to a controller. The controller controls the extension and retraction of different power lifting components 13 sequentially or alternately at time intervals according to a preset control program, thereby driving the corresponding lifting plate 12 to move up or down.
[0042] In another embodiment, a track 15 is provided along the length of the pressure-bearing platform 11, and a movable base 14 capable of movement is provided on the track 15. A powered lifting component 13 is installed on the movable base 14. By moving the position of the powered lifting component 13, it can be moved to different positions under the lifting plates 12. By moving the movable base 14 along the track 15, the powered lifting component 13 is moved sequentially to directly below different lifting plates 12, and the powered lifting component 13 passes through the corresponding through hole 16 to cooperate with the lifting plate 12, thereby driving the target lifting plate 12 to move up and down.
[0043] This implementation method reduces the number of power components by sharing the power lifting component 13, while ensuring the lifting function is realized. This helps to reduce the overall structural cost and facilitates maintenance.
[0044] In one implementation, a controller is installed below the pressure platform 11. The controller is electrically connected to the power lifting component 13 and to a position sensor installed on the track 15. The position sensor detects the current position of the moving base 14 on the track 15 and feeds the position signal back to the controller. When a certain lifting plate 12 needs to be raised or lowered for maintenance, the controller controls the power lifting component 13 to move along the track 15 with the moving base 14 to directly below the target lifting plate 12 according to the preset position of the corresponding lifting plate 12. After the position sensor detects that the power lifting component 13 is aligned with the target lifting plate 12, it sends a position signal to the controller. The controller then sends a lifting command to the power lifting component 13, causing the power lifting component 13 to extend or retract, thereby driving the corresponding lifting plate 12 to rise or fall. Through the periodic control of the power lifting component 13 by the controller, different lifting plates 12 can complete the lifting and lowering actions in sequence, realizing the separate maintenance of the bagged masterbatch 5 and reducing the long-term static pressure effect.
[0045] The lifting height of the lifting plate 12 is 10mm-100mm. While ensuring the overall stability of the bag, it can effectively cause changes in the state of the masterbatch inside the bag, thereby alleviating the problem of static pressure caking of bagged masterbatch.
[0046] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes to the technical solution and inventive concept of the present invention within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention.
