Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation, in particular to a coiled material tray rack. Background Art

[0002] The copper foil and aluminum foil used in lithium batteries are coils with mandrels. There are special requirements for the transportation of copper foil rolls and aluminum foil rolls: 1. Except for the mandrel, the packaging film of the copper foil and aluminum foil rolls cannot come into contact with any object to avoid damaging the copper foil and aluminum foil. Therefore, a mandrel-suspended packaging and transportation method must be adopted; 2. The packaging and transportation equipment itself and its fixation to the mandrel must be very stable to avoid shaking during transportation, and the driving direction must be perpendicular to the axis direction of the mandrel to avoid loosening the coils during transportation; 3. Copper foil and aluminum foil must be strictly prevented from contacting metal foreign matter, such as rust, to prevent quality problems with lithium batteries.

[0003] Due to the above special requirements, copper foil rolls and aluminum foil rolls are currently packaged and transported in wooden boxes. However, wooden boxes are not environmentally friendly, cannot be folded, have high recycling and transportation costs, and have a short service life. Therefore, it is very necessary to develop foldable and recyclable turnover boxes. Utility Model Content

DETAILED DESCRIPTION

[0052] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0053] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0054] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0055] The utility model provides a coil material tray rack, which is used for loading coil materials and is convenient for transporting the coil materials. The coil material tray rack can be folded, and the recycling and transportation cost is low.

[0056] The coil includes a core shaft. The coil tray rack supports the two ends of the core shaft along the axial direction so that the coil is suspended. Therefore, the coil tray rack is a hanging tray rack.

[0057] Figure 1 Schematic diagram of the structure of the coil tray rack in this embodiment is shown. Figure 2 The schematic diagram of the structure of the coil tray rack loading coils is shown. Figure 1 and Figure 2The coil tray rack 2 includes a chassis 21, two pairs of side wall assemblies arranged in pairs, and a plurality of locking members 24. Each pair of side wall assemblies includes side walls arranged on opposite sides of the chassis 21, and each side wall is rotatably connected to the chassis 21, so that the side walls can be folded inward onto the chassis 21. The side walls of one pair of side wall assemblies are provided with support beams 233 for supporting the coil 1 and pressing members for pressing the coil 1, that is, the core shaft 11 is supported by the support beams 233 on the two side walls, and the pressing members press the core shaft 11. The tops of the two side walls of at least one pair of side wall assemblies are flush and have different heights, which ensures that one side wall is located above the other side wall when folded, avoiding interference between the two side walls when folded. The locking member 24 is used to lock the side walls in an upright state, so that each side wall remains upright to load the coil 1. Therefore, the coil material tray rack 2 can load the coil material 1 in an unfolded state to facilitate the transportation of the coil material 1, and can be recycled and transported in a folded state, so that it can be repeatedly used, reducing the transportation cost.

[0058] For the convenience of description, the side wall extending in the longitudinal direction is defined as the longitudinal side wall 22, and the side wall extending in the transverse direction is defined as the transverse side wall 23. The core shaft 11 is placed on the coil tray rack 2 in a manner that the axial direction extends in the longitudinal direction.

[0059] Combination Figure 3-Figure 6 The cross section of the chassis 21 is square. The chassis 21 is a frame structure. Specifically, the chassis 21 includes four columns 211, two longitudinal beams 212 and two cross beams 213. The two longitudinal beams 212 are arranged in parallel and spaced apart, and each longitudinal beam 212 extends in the longitudinal direction, and each end of each longitudinal beam 212 is connected to a column 211 respectively. The two cross beams 213 are arranged in parallel and spaced apart, and each cross beam 213 extends in the transverse direction, and each end of each cross beam 213 is connected to a column 211 respectively.

[0060] There is a vertical interval between the two longitudinal beams 212 , that is, there is a height difference between the two longitudinal beams 212 , wherein one longitudinal beam 212 is higher and the other longitudinal beam 212 is lower.

[0061] The top of each column 211 extends upward beyond the longitudinal beam 212 and the transverse beam 213 .

[0062] In this embodiment, the chassis 21 further includes a first reinforcing beam disposed between the two cross beams 213 and extending in the longitudinal direction, and a plurality of second reinforcing beams extending in the transverse direction, a second reinforcing beam is disposed between two adjacent first reinforcing beams, and a second reinforcing beam is disposed between the first reinforcing beam and the longitudinal beam 212. The first reinforcing beam and the second reinforcing beam increase the strength of the chassis 21, and enable a forklift to lift the chassis 21 and thus the entire coil pallet rack 2.

[0063] Two pairs of side wall assemblies are arranged on the chassis 21. Each pair of side wall assemblies includes side walls arranged on opposite sides of the chassis 21, wherein the side walls of one pair of side wall assemblies extend longitudinally, and the side walls of the other pair of side wall assemblies extend transversely, that is, the two longitudinal side walls 22 extend longitudinally and correspond one-to-one to the two longitudinal beams 212, and the two transverse side walls 23 extend transversely and correspond one-to-one to the two transverse beams 213.

[0064] In this embodiment, the heights of the two longitudinal side walls 22 are different, and the heights of the two transverse side walls 23 are the same. In other embodiments, the heights of the two transverse side walls 23 may be different, and the heights of the two longitudinal side walls 22 may be the same, or the heights of the two longitudinal side walls 22 may be different, and the heights of the two transverse side walls 23 may be different.

[0065] Side walls of different heights can be folded on the chassis 21 in a manner that the two side walls are located in planes at different heights, thereby avoiding mutual interference between the two side walls. Furthermore, the side walls of the same height are configured to be able to rise and fall relative to the chassis 21, so that when folded, they can also be folded on the chassis 21 in a manner that the two side walls are located in planes at different heights. That is, when the tops of the two side walls of one pair of side wall assemblies are flush and the heights are different, the two side walls of the other pair of side wall assemblies have the same height and can be raised and lowered relative to the chassis 21.

[0066] The support beam 233 supporting the coil 1 and the pressing member pressing the coil 1 can be arranged on the longitudinal side wall 22 or on the transverse side wall 23, and can be arranged according to actual needs. In this embodiment, the support beam 233 and the pressing member are arranged on the transverse side wall 23 as an example.

[0067] Therefore, the side wall assembly will be introduced below with the assumption that the two longitudinal side walls 22 have different heights, the two transverse side walls 23 have the same height, and the support beam 233 and the clamping member are located on the transverse side walls 23 .

[0068] The two longitudinal side walls 22 are arranged corresponding to the two longitudinal beams 212. A second connecting pipe 224 is arranged at the bottom of each longitudinal side wall 22, and the axis of the second connecting pipe 224 extends in the longitudinal direction. A first connecting pipe 214 is arranged at the top of the longitudinal beam 212, and the axis of the first connecting pipe 214 extends in the longitudinal direction. The hinge shaft extends in the longitudinal direction and is simultaneously arranged in the first connecting pipe 214 and the second connecting pipe 224, so as to realize the rotatable connection between the longitudinal side wall 22 and the longitudinal beam 212, and the longitudinal side wall 22 cannot be raised or lowered relative to the longitudinal beam 212.

[0069] In this embodiment, there are three first connecting tubes 214, which are respectively located at the two ends and the middle of the longitudinal beam 212. There are six second connecting tubes 224, that is, two second connecting tubes 224 correspond to one first connecting tube 214, and the two second connecting tubes 224 are arranged at the longitudinal ends of the corresponding first connecting tube 214. There are three hinge shafts, which are arranged one by one with the first connecting tubes 214.

[0070] The two longitudinal side walls 22 have different heights, that is, their vertical dimensions are different when erected, and the longitudinal side wall 22 with a larger height is arranged corresponding to the longitudinal beam 212 with a lower height, so that the tops of the two longitudinal side walls 22 are flush. The heights of the two longitudinal side walls 22 are both smaller than the lateral dimensions of the chassis 21, so that the longitudinal side walls 22 can be folded on the chassis 21.

[0071] When the two longitudinal side walls 22 are folded, the longitudinal side wall 22 on the lower longitudinal beam 212 is first folded inward on the chassis 21, and then the longitudinal side wall 22 on the higher longitudinal beam 212 is folded, so that the two longitudinal side walls 22 are stacked on each other, avoiding interference between the two longitudinal side walls 22. In this embodiment, the two longitudinal side walls 22 extend in the horizontal direction after being stacked.

[0072] See also Figure 7 The longitudinal side wall 22 specifically includes a top side beam 221 and a bottom side beam 222 arranged in parallel and spaced apart, and two longitudinal connecting beams 223 arranged in parallel and spaced apart, the top side beam 221 and the bottom side beam 222 extend in the longitudinal direction, and the two ends of the longitudinal connecting beam 223 are respectively connected to the top side beam 221 and the bottom side beam 222. The second connecting pipe 224 is arranged at the bottom of the bottom side beam 222.

[0073] Furthermore, the longitudinal side wall 22 further includes two diagonal braces 225. The two diagonal braces 225 cross each other, one end of each diagonal brace 225 is connected to the bottom side beam 222, and the other end is connected to the upper part of the longitudinal connecting beam 223, and there is a gap between the diagonal brace 225 and the top side beam 221. By setting the diagonal brace 225, the stability of the longitudinal side wall 22 is enhanced, the pulling force and supporting force of the longitudinal side wall 22 on the transverse side wall 23 are increased, and the shaking of the transverse side wall 23 is reduced.

[0074] The two horizontal side walls 23 are arranged corresponding to the two horizontal beams 213, and the heights of the two horizontal side walls 23 are the same. Specifically, the two horizontal ends of the bottom of the horizontal side wall 23 are provided with a rotating shaft 234, and the column 211 of the chassis 21 is provided with a mounting hole 2111, the length of the mounting hole 2111 extends vertically, and the two rotating shafts 234 are respectively inserted into the mounting holes 2111 of the two columns 211. The axes of the rotating shaft 234 and the mounting hole 2111 both extend horizontally. The mounting hole 2111 is provided on the inner side of the column 211 facing the other column 211 in the horizontal direction.

[0075] In this embodiment, each column 211 is provided with a mounting hole 2111 along the inner side thereof in the transverse direction.

[0076] The cooperation between the rotating shaft 234 and the mounting hole 2111 enables the lateral side wall 23 to not only rotate relative to the chassis 21 and be folded on the chassis 21, but also to be lifted and lowered to avoid interference between the lateral side wall 23 and the top of the chassis 21 during the unfolding, erecting and folding process, and to avoid interference between the two lateral side walls 23. Therefore, the connection between the lateral side wall 23 and the chassis 21 is a movable hinge that can be lifted and lowered and rotated.

[0077] See also Figure 8-Figure 10 The lateral side wall 23 includes a bottom beam 231, end beams 232 arranged at both ends of the bottom beam 231, and a support beam 233 connected between the two end beams 232. The support beam 233 is located in the middle of the end beam 232.

[0078] The two rotating shafts 234 are disposed at two opposite ends of the bottom beam 231 .

[0079] Preferably, each end beam 232 is connected to the bottom beam 231 through a transition beam, so that the end beam 232 extends outward beyond the end of the bottom beam 231. Specifically, the two ends of the transition beam are spaced apart in the lateral direction, the inner end is connected to the bottom beam 231, and the outer end is connected to the end beam 232. The transition beam includes a first section parallel to the end beam 232 and a second section parallel to the bottom beam 231, one end of the first section is connected to the end of the bottom beam 231, and the other end is connected to the second section, the second section is located outside the first section, and the outer end of the second section is connected to the end beam 232.

[0080] The support beam 233 has a support groove with an opening facing upward, and the inner wall of the support groove is arc-shaped. Specifically, the support beam 233 includes an arc segment and straight edge segments arranged at both ends of the arc segment, and the concave surface of the arc segment faces upward, and the arc segment forms a support groove. The support groove is used to accommodate the core shaft 11 of the coil 1.

[0081] Furthermore, a reinforcing beam is provided between the support beam 233 and the bottom beam 231, and the reinforcing beam extends vertically. The reinforcing beam is located at the center of the arc segment. Two support columns and two reinforcing beams are provided on the chassis 21, and the support columns extend vertically and correspond to the reinforcing beams. The reinforcing beams are provided at the bottom of the support columns and connected between the two columns 211, so that when the coil 1 is loaded, the gravity of the coil 1 is transmitted to the reinforcing beams through the reinforcing beams and the support columns.

[0082] A support pad 236 is also provided in the support groove to support the core shaft 11 of the coil 1. The support pad 236 is arc-shaped, and the upper surface of the support pad 236 constitutes a support surface for supporting the core shaft 11. The material of the support pad 236 is an elastic material, for example, polyurethane or rubber.

[0083] Specifically, the support surface is provided with a plurality of countersunk holes, and bolts are passed through the countersunk holes to fix the support pad 236 to the top of the arc segment.

[0084] A limit plate 237 is also provided on the outer side of the support beam 233. The limit plate 237 is provided corresponding to the support groove and protrudes the support pad 236 to limit the axial movement of the core shaft 11 in the support groove. Specifically, the outer contour of the limit plate 237 includes an inner edge, side edges arranged at both ends of the inner edge, and an outer edge. The inner edge is arc-shaped.

[0085] Preferably, the inner arc edge is concentric with the arc-shaped support pad 236, and the radius of the inner arc edge is smaller than the radius of the support pad 236. That is, the radius of the circle where the inner arc edge is located is smaller than the radius of the circle where the support pad 236 is located, so that the inner arc edge protrudes from the support pad 236 in the direction away from the bottom beam 231.

[0086] In this embodiment, the limiting plate 237 is in a fan ring shape. The inner edge and the outer edge are both arc-shaped. In other embodiments, the outer edge can also be a straight edge or in other shapes, which can be set according to actual needs.

[0087] The outer edge of the limiting plate 237 is connected to the two straight side sections of the support beam 233 and the reinforcing beam at the same time, increasing the connection strength between the arc section and the straight side section of the support beam 233, and increasing the connection strength between the support beam 233 and the reinforcing beam, thereby increasing the strength of the lateral side wall 23.

[0092] A hinge seat and a support seat are provided on the support beam 233 at intervals, and the hinge seat and the support seat are arranged at opposite ends of the support groove.

[0093] The connecting end is hingedly connected to the hinge seat, and a clamping groove with an opening away from the connecting end is provided on the clamping end. The clamping beam 2351 is hingedly connected to the hinge seat through the connecting end, so that the clamping beam 2351 can rotate relative to the support beam 233, and cover the opening of the support groove or expose the opening of the support groove.

[0094] Specifically, in this embodiment, a shaft sleeve is provided at the connection end, and the hinge seat includes two seat plates arranged in parallel and spaced apart and a hinge shaft, the seat plate is arranged at the top of a straight side section of the support beam 233, the hinge shaft is located between the two seat plates, the hinge shaft extends in the longitudinal direction, the shaft sleeve is located between the two seat plates and sleeved on the outer circumference of the hinge shaft, so as to realize the hinge connection between the clamping member and the support beam 233.

A baffle plate 2382 is provided on the side wall where the pressing member is located, and a hook hole 2383 is provided on the baffle plate 2382. When the pressing member is rotated to expose the opening of the support groove, the hook head can extend into the hook hole 2383. Specifically, the hook plate 2381 is provided on the raised surface of the pressing beam 2351, and the baffle plate 2382 is provided on the inner side of the end beam 232. Through the cooperation of the hook plate 2381 and the hook hole 2383, the pressing member is kept in the open position to prevent the pressing member from being accidentally closed and causing harm to personnel.

[0098] Preferably, an extension arm is provided on the hook plate 2381 , which protrudes out of the hook plate 2381 in the longitudinal direction. The extension arm is used for the operator to grasp and hook the hook plate 2381 into the hook hole 2383 .

[0099] A plurality of locking members 24 are arranged at intervals along the circumference of the chassis 21. Each locking member 24 is arranged at the top end of one of the side walls, and is used to lock the adjacent two side walls in the upright state so that the two pairs of side wall assemblies can remain upright. In this embodiment, the number of locking members 24 is four, and each longitudinal side wall 22 corresponds to two locking members 24, and the locking members 24 are located at the longitudinal ends of the longitudinal side walls 22. In other embodiments, the locking members 24 can also be arranged at other positions according to actual needs to ensure that the adjacent two side walls in the upright state are locked so that the two pairs of side wall assemblies can remain upright.

[0100] Specifically, a lock hole is provided on the lateral side wall 23. Figure 7 Each locking member 24 includes a lock support 241 and a lock rod 242. The lock support 241 is fixed on the longitudinal side wall 22. The lock rod 242 is arranged on the lock support 241 and can move relative to the lock support 241 to be inserted into or out of the lock hole. Specifically, a through hole is provided on the longitudinal connecting beam 223 of the longitudinal side wall 22 for the lock rod 242 to pass through. At this time, the transverse side wall 23 is the first side wall, and the longitudinal side wall 22 is the second side wall.

[0101] The lock support 241 is fixed to the bottom of the top side beam 221 of the longitudinal side wall 22 and is located at the longitudinal end of the longitudinal side wall 22 .

[0102] Furthermore, the locking rod 242 can rotate relative to the locking support 241. The through hole and the locking hole are both long holes extending in the vertical direction, and the locking rod 242 is a hook head locking rod 242. The locking rod 242 can rotate until the hook head enters the locking hole, and after the locking rod 242 rotates, it cannot be withdrawn to achieve locking.

[0103] Preferably, the locking member 24 further includes a handle 243 fixed on the locking rod 242 for an operator to grasp to facilitate moving and rotating the locking rod 242 .

[0104] The locking member 24 further includes a cushion block 244 disposed outside the lock support 241. The cushion block 244 and the lock rod 242 are spaced apart in the vertical direction. The cushion block 244 provides a space between the lock support 241 and the longitudinal connecting beam 223 of the longitudinal side wall 22, so that when the lock rod 242 is withdrawn from the lock hole, i.e., when the locking member 24 is in the open state, the hook head portion of the lock rod 242 can be located within the space. In this embodiment, the cushion block 244 is located below the lock rod 242. The provision of the cushion block 244 can increase the strength of the lock support 241 and prevent the tension of the lock rod 242 from deforming the lock support 241.

[0105] Furthermore, a pad 25 is provided on the surface of the transverse side wall 23 facing the longitudinal side wall 22 . A through hole is provided on the pad 25 . The through hole is provided corresponding to the lock hole and completely exposes the lock hole.

[0106] A limit pin 26 extends from the surface of the first side wall toward the second side wall, and a clearance hole 2321 and a limit hole 2231 are provided on the surface of the second side wall toward the first side wall. When the four side walls are assembled, the limit pin 26 can be inserted into the clearance hole 2321 and the limit hole 2231. At this time, the first side wall is the transverse side wall 23, and the second side wall is the longitudinal side wall 22. And the side of the first side wall away from the limit pin 26 is provided with a clearance hole 2321. When the two transverse side walls 23 are folded, the clearance hole 2321 of the transverse side wall 23 folded first at the bottom can accommodate the limit pin 26 of the transverse side wall 23 folded later at the top, so as to make the folding smooth, reduce the folding height and prevent the limit pin 26 from hitting the end beam 232.

[0107] That is, a limiting pin 26 extends from the surface of the transverse side wall 23 toward the longitudinal side wall 22, and a limiting hole 2231 is formed on the surface of the longitudinal side wall 22 toward the transverse side wall 23, and the limiting pin 26 can be inserted into the limiting hole 2231. Preferably, the limiting pin 26 extends from the pad 25.

[0108] Therefore, the pad 25 can not only increase the strength of the lock hole, but also facilitate the connection between the limit pin 26 and the end beam 232 of the lateral side wall 23, and at the same time, it can also avoid interference between the longitudinal side wall 22 and the lateral side wall 23 when folding.

[0109] The locking member 24 limits the relative movement of the longitudinal side wall 22 and the transverse side wall 23 in the longitudinal direction, and the cooperation of the limiting pin 26 and the limiting hole 2231 limits the relative movement of the longitudinal side wall 22 and the transverse side wall 23 in the transverse and vertical directions, thereby achieving relative fixation between the longitudinal side wall 22 and the transverse side wall 23. Therefore, the gravity and transportation inertia of the coil 1 borne by the transverse side wall 23, as well as the stacking gravity and transportation inertia, cannot cause the transverse side wall 23 to rotate and move, thereby reducing the shaking of the coil tray rack 2 during transportation, and meeting the special transportation requirements of copper foil rolls and aluminum foil rolls.

[0110] In other embodiments not shown, the lateral side wall 23 may be connected to the longitudinal side wall 22 instead of being connected to the limiting pin 26, but may be connected to the chassis 21. The specific configuration may be based on actual needs.

[0111] In this embodiment, the base 21 , the lateral side walls 23 and the longitudinal side walls 22 are made of steel.

[0112] Combination Figure 11-13The coil tray rack 2 also includes a protective member for protecting the coil 1 on the coil tray rack 2 to prevent the coil 1 from being collided and contaminated. Specifically, the protective member includes an upper protective cover 271 and a lower protective cover 272 that are detachably connected. The upper protective cover 271 has a first accommodating cavity with an opening at one end, and the lower protective cover 272 has a second accommodating cavity with an opening at one end. The upper protective cover 271 and the lower protective cover 272 together enclose a space for accommodating the coil 1, and the opposite ends of the accommodating space are provided with a protruding opening for the core shaft 11 of the coil 1 to pass through. That is, the bottom of the upper protective cover 271 is open, and the top of the lower protective cover 272 is open, and the upper protective cover 271 is located on the top of the lower protective cover 272.

[0113] The upper protective cover 271 and the lower protective cover 272 are detachably connected by buckling. Furthermore, the connection between the upper protective cover 271 and the lower protective cover 272 and the buckling connection between the upper protective cover 271 and the lower protective cover 272 and the core shaft 11 form a sealing edge, and a sealing strip is arranged inside the sealing edge, so that the protective member seals the coil 1 inside the protective member to prevent the coil 1 from contacting metal foreign matter, rain, moisture and other pollutants.

[0114] The upper protective cover 271 and the lower protective cover 272 can also be tightly bound by a packing tape so that the sealing strip inside the sealing edge is compressed and sealed.

[0115] Furthermore, the coil tray rack 2 further comprises a plurality of binding parts arranged on one set of the side wall components. Both ends of the side wall of the side wall component are provided with binding parts. In this embodiment, the binding parts are arranged on the transverse side wall 23.

[0116] Specifically, the binding part includes rope binding plates disposed at both ends of the top of the support beam 233, and there is a gap in the lateral direction between the rope binding plates and the corresponding end beams 232. In this embodiment, the rope binding plate is the baffle plate 2382, that is, the two are the same plate, which can not only hook with the hook plate 2381, but also cooperate with the end beam 232 to accommodate the binding rope.

[0117] Preferably, the surface of the rope tying plate opposite to the end beam 232 is an inclined surface, which is inclined from bottom to top toward the center of the horizontal side wall 23 to form a receiving groove that is wide at the top and narrow at the bottom, so that the binding rope can enter the bottom of the receiving groove under the guidance of the inclined surface. In this embodiment, the rope baffle 2382 is a steel plate bent part.

[0118] The binding part also includes a heightening seat arranged on the support beam 233, and the rope baffle 2382 is arranged on the heightening seat to increase the height of the rope baffle 2382, thereby increasing the binding height of the binding rope and avoiding interference between the binding rope and the sealing edge.

[0119] The upper protective cover 271 and the lower protective cover 272 are made of non-metallic materials. Specifically in this embodiment, the upper protective cover 271 and the lower protective cover 272 are both plastic parts.

[0120] Preferably, the cross-sections of the upper protective cover 271 and the lower protective cover 272 are both trapezoidal in shape with a large open end and a small closed end.

[0121] The downward protrusion on the bottom surface of the lower protective cover 272 cooperates with the chassis 21 to achieve position limiting, ensuring that the lower protective cover 272 is centered.

[0122] The upper protective cover 271 and the lower protective cover 272 can be inserted together for recycling to increase the recycling amount and reduce the recycling transportation cost. In this embodiment, the upper protective covers 271 are inserted into each other, and the lower protective covers 272 are inserted into each other.

[0123] The coil tray rack 2 can be folded and stacked after being folded. Fig.14 After stacking, the materials are recycled and transported, which reduces the recycling and transportation cost. The present application sets a stacking portion 217, an upper stacking member 215 and a lower stacking member 216 on the chassis 21 to limit the displacement between the stacked coil material tray racks 2.

[0124] Specifically, stacking parts 217 are provided at the bottom of the four corners of the chassis 21, and each stacking part 217 includes a first stacking surface 2171, a second stacking surface 2172, a first guide surface 2173, and a second guide surface 2174. The first stacking surface 2171 and the second stacking surface 2172 are located in the same horizontal plane, and the two are perpendicular to each other and correspond to the adjacent two side walls respectively. The first guide surface 2173 is inclined from the inner side of the first stacking surface 2171 from top to bottom and inwardly, and the second guide surface 2174 is inclined from the inner side of the second stacking surface 2172 from top to bottom and inwardly. It is inclined inward, and the first stacking surface 2171 and the second stacking surface 2172 are adjacent to each other, and the first guide surface 2173 and the second guide surface 2174 are adjacent to each other; after the assembled coil pallet rack 2, when one coil pallet rack 2 is stacked on another coil pallet rack 2, the first stacking surface 2171 and the second stacking surface 2172 of the upper coil pallet rack 2 respectively abut against the two side walls of the lower coil pallet rack 2, and the first guide surface 2173 and the second guide surface 2174 of the upper coil pallet rack 2 are respectively located on the inner side of the two side walls of the lower coil pallet rack 2 and are limited.

[0125] When stacking, of the two coil pallet racks 2 adjacent to each other in the vertical direction, the one located on top is the upper coil pallet rack 2 , and the one located on the bottom is the lower coil pallet rack 2 .

[0126] In this embodiment, the first stacking surface 2171 of the upper coil pallet rack 2 abuts against the surface of the top side beam 221 of the longitudinal side wall 22 of the lower coil pallet rack 2 away from the bottom side beam 222, and the second stacking surface 2172 of the upper coil pallet rack abuts against the surface of the end beam 232 of the transverse side wall 23 of the lower coil pallet rack 2 away from the bottom beam 231, the first guide surface 2173 of the upper coil pallet rack 2 is located on the inner side of the top side beam 221 of the longitudinal side wall 22 of the lower coil pallet rack 2 and is limited by the top side beam 221, and the second guide surface 2174 of the upper coil pallet rack 2 is located on the inner side of the end beam 232 of the transverse side wall 23 of the lower coil pallet rack 2 and is limited by the end beam 232.

[0127] The stacking parts 217 on the chassis 21 are simultaneously in contact with the adjacent two side walls, so as to limit the stacked coil tray rack 2. The first stacking surface 2171 and the first guide surface 2173 cooperate with the top side beam 221 to achieve lateral limitation, and the second stacking surface 2172 and the second guide surface 2174 cooperate with the end beam 232 to achieve longitudinal limitation.

[0128] In this embodiment, through the limiting mode of the cooperation between the first guide surface 2173 and the longitudinal side wall 22, and the cooperation between the second guide surface 2174 and the transverse side wall 23, when the coil material pallet rack 2 is stacked, there are no upwardly protruding stacking parts on the top of the longitudinal side wall 22 and the transverse side wall 23, which facilitates the laying of the rainproof cloth.

[0129] Furthermore, lower stacking members 216 are provided at the bottom of the four corners of the chassis 21 , and upper stacking members 215 are provided at the top. The lower stacking members 216 cooperate with the upper stacking members 215 to achieve stacking of the folded coil tray rack 2 .

[0130] Specifically, the upper stacking member 215 includes an upper stacking plate 2151 and an upper guide plate 2152 disposed on the outer side of the top of the upper stacking plate 2151. The upper stacking plate 2151 is disposed on the top of the column 211. The top of the upper stacking plate 2151 extends horizontally to form an upper stacking surface, and the inner side surface of the upper guide plate 2152 tilts outward from bottom to top to form an upper guide surface. The lower stacking member 216 includes a lower stacking plate 2161 and a lower guide plate 2162 disposed on the outer side of the lower stacking plate 2161. The lower stacking plate 2161 is disposed at the bottom of the column 211. The bottom of the lower stacking plate 2161 extends horizontally to form a lower stacking surface, and the outer side surface of the lower guide plate 2162 tilts outward from bottom to top to form a lower guide surface. The lower stacking plate 2161 overlaps the upper stacking plate 2151, and the upper guide plate 2152 and the lower guide plate 2162 fit each other.

[0131] In this embodiment, the upper guide surface is located at the transverse outer end of the upper stacking member 215, and the upper guide surface extends obliquely from the upper stacking surface in the transverse direction from bottom to top to outward. The lower guide surface is located at the transverse outer end of the lower stacking member 216, and the lower guide surface extends obliquely from the lower stacking surface in the transverse direction from bottom to top to outward.

[0132] Preferably, the lower stacking surface is coplanar with the second stacking surface 2172 .

[0133] When the folded coil pallet rack 2 is stacked, the second stacking surface 2172 and the lower stacking surface of the upper coil pallet rack 2 abut against the upper stacking surface of the lower coil pallet rack 2, and the lower guide surface of the upper coil pallet rack 2 is located on the inner side of the upper guide surface of the lower coil pallet rack 2 and is limited by the upper guide surface to limit the lateral displacement of the upper coil pallet rack 2 relative to the lower coil pallet rack 2. The second guide surface 2174 of the upper coil pallet rack 2 is located on the inner side of the upper stacking member 215 of the lower coil pallet rack 2 and is limited by the upper stacking member 215 to limit the longitudinal displacement of the upper coil pallet rack 2 relative to the lower coil pallet rack 2.

[0134] Furthermore, the upper stacking member 215 also includes a first baffle 2153 arranged on the upper stacking plate 2151, and the first baffle 2153 is also connected to the outer side of the upper guide plate 2152. A connecting member 239 is provided at the bottom of the end beam 232 of the side wall of one group of side wall assemblies. The connecting member 239 includes a base plate 2391 and an extension wall 2392. The extension wall 2392 extends downward from the inner side of the base plate 2391. The base plate 2391 includes a second baffle 2393. The second baffle 2393 is arranged on the inner side of the base plate 2391 and extends outward from the outer end surface of the base plate 2391 along the length direction of the side wall.

[0135] Specifically, the first retaining wall 2153 connects the upper stacking surface and the upper guide surface and is located outside the upper stacking member 215. In this embodiment, the connecting member 239 is disposed at the bottom of the end beam 232 of the lateral side wall 23. The rotating shaft 234 of the lateral side wall 23 extends outwardly from the lower end of the extension wall 2392 in the lateral direction.

[0136] When the lateral side wall 23 is tilted outward, the first retaining wall 2153 abuts against the second retaining wall 2393, so that the lateral side wall 23 is kept in an inclined state, so as to facilitate the assembly and folding operation of the coil tray rack 2. When the lateral side wall 23 is in an upright state, the base plate 2391 abuts against the upper stacking surface to transmit the stacking force.

[0137] The lower stacking member 216 is further provided with a first avoidance groove 2163 for accommodating the first retaining wall 2153, and the base plate 2391 is further provided with a second avoidance groove 2394 for accommodating the first retaining wall 2153. When the coil tray rack 2 is folded and stacked, the first retaining wall 2153 is located in the first avoidance groove 2163. When the lateral side wall 23 is in an inclined or upright position, the first retaining wall 2153 is located in the second avoidance groove 2394.

[0138] The steps of loading the coil 1 on the coil tray rack 2 are as follows:

[0139] First, lift the horizontal side wall 23 upward to tilt it outward and stand it upright, then lift the vertical side wall 22 and make the horizontal side wall 23 stand upright, so that the limit pin 26 is inserted into the limit hole 2231. Then, the vertical side wall 22 and the horizontal side wall 23 that are standing upright are locked by the locking member 24. Then, put the strapping tape on the chassis 21, put the lower protective cover 272 in and limit it with the chassis 21, open the clamping member and fix it with the hook plate 2381. Then, insert the lifting pipe into the mandrel 11 of the coil 1, and put the two ends of the mandrel 11 into the support groove by lifting the two ends of the lifting pipe, so that the coil 1 enters the lower protective cover 272, then pull out the lifting pipe, buckle the upper protective cover 271, and then tighten the upper protective cover 271 and the lower protective cover 272 with the strapping tape, open the hook plate 2381 and lock the clamping member through the operating member 2352, and complete the loading of the coil 1.

[0140] The operation steps for unloading the coil 1 are opposite to the operation steps for loading the coil 1 .

[0141] When the coil material tray rack 2 is recycled, part of the coil material tray rack 2 is folded and stacked, and part of the coil material tray rack 2 is in an upright unfolded state. The upright unfolded coil material tray rack 2 is used to accommodate a plurality of upper protective covers 271 or lower protective covers 272 inserted together. The folded coil material tray racks 2 are stacked on each other, and the movement between the upper coil material tray rack 2 and the lower coil material tray rack 2 is limited by the cooperation of the upper stacking member 215 of the lower coil material tray rack 2 and the lower stacking member 216 of the upper coil material tray rack 2, as well as the function of the stacking portion 217.

[0142] During recycling and transportation, the upright unfolded coil tray rack 2 can be stacked on the folded coil tray rack 2, or can be independent. The specific arrangement is based on actual needs.

[0143] Since the above-mentioned coil material tray rack 2 includes two sets of side wall components arranged in pairs, each side wall component includes two side walls, and each side wall is connected to the chassis 21, and the core shaft 11 of the coil material 1 is fixed by the support beam 233 and the clamping member, wherein the two longitudinal side walls 22 are hingedly connected to the chassis 21 and cannot be moved, and the two longitudinal side walls 22 are provided with diagonal braces 225 to improve their stability, and the transverse side walls 23 and the longitudinal side walls 22 are firmly connected in the longitudinal, transverse and vertical directions by the locking member 24 and the limit pin 26, so that the transverse side walls 23 are firmly fixed, so that the coil material 1 shakes very little during transportation. In addition, the top of the two longitudinal side walls 22 are flush, the height is different, and the transverse side wall 23 can be raised and lowered, so that the top surface of the coil material tray rack 2 is flat after folding. The stacking structure with the top of the coil material tray rack 2 flush and without protruding stacking members is adopted, which is conducive to laying rainproof cloth.

[0144] In this embodiment, the support beam 233 and the pressing member are arranged on the transverse side wall 23, and the transverse side wall 23 is the main load-bearing structure for stacking, so the strength of the transverse side wall 23 needs to be strong, so as to facilitate the support of the coil 1. The strength of the transverse side wall 23 can be increased by increasing the thickness of the support beam 233, the bottom beam 231, the end beam 232 and the transition beam on the transverse side wall 23. The strength of the longitudinal side wall 22 is relatively small, so as to reduce the weight and the folded thickness.

[0145] In other embodiments, the support beam 233 and the pressing member may also be disposed on the longitudinal side wall 22 .

[0146] In summary, the coil tray rack 2 is made of steel, and its size can be flexibly produced according to needs, which is convenient for coping with the packaging and transportation needs of copper foil rolls and aluminum foil rolls of various specifications, and meets the strength requirements for loading large-size copper foil rolls and aluminum foil rolls in the future. The coil tray rack 2 is equipped with a protective member to prevent the copper foil rolls and aluminum foil rolls from contacting foreign matter generated by the steel structure. The coil tray rack 2 has a stable structure and little shaking during transportation.
