Description

Technical Field

[0001] This utility model relates to a tray, and more particularly to a powder bag transfer tray. Background Technology

[0002] Currently, most powder bag transfer pallets on the market are traditional flat-panel structures or pallets with only simple railings around the edges. These pallets have a simple overall structure; a flat pallet is simply a flat support panel that relies on the friction of the panel itself to hold the powder bags. However, this structure has significant shortcomings in practical use: when there is slight shaking or the pallet tilts during transfer, the lack of effective restraint on the bottom of the powder bags allows them to easily slide on the pallet surface. Once the bottom powder bags slide, the powder bags stacked on top lose stable support, leading to swaying or even slipping. This not only affects transfer efficiency but may also cause material loss due to falling powder bags, increase the need for manual adjustment and sorting during the transfer process, and bring inconvenience to the entire transfer flow. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a powder bag transfer tray.

[0004] The technical solution is as follows: A powder bag transfer pallet includes a pallet body, a pad, rotating rods, a stop bar, and a rotating shaft. The pallet body consists of a platform and multiple legs integrally formed with the platform, with forklift clearance formed between adjacent legs on the same side. A pad is provided transversely between the legs on the front and rear sides. Folding railing units are provided on both the front and rear sides of the platform. Each folding railing unit includes: multiple parallel rotating rods, the first end of which is rotatably connected to the side of the platform; multiple rotating shafts, each fixedly set at the second end of a rotating rod; a stop bar is hinged to multiple rotating rods on the same side via the rotating shaft to form a folding linkage mechanism; a locking mechanism is provided on the stop bar to lock the unfolding angle of the stop bar relative to the rotating rods; wherein, the rotating rods, the stop bar, and the rotating shaft together constitute a horizontally folding railing, and after the stop bar is folded, its top is on the same horizontal plane as the platform of the pallet body.

[0005] Furthermore, the locking mechanism includes a pull rod, a spring, and an insert, wherein: at least one rotating shaft has a locking hole in the radial direction; a pull rod is slidably disposed inside the stop rod, and an insert adapted to the locking hole is fixed at the end of the pull rod; a spring is sleeved on the outer periphery of the pull rod, and the two ends of the spring abut against the pull rod flange and the inner wall of the stop rod, respectively; the insert is kept in the locking state with the locking hole under the action of the spring force.

[0006] Furthermore, it also includes pads, with pads provided on the table surface of the tray body and on one side of the top of the stop bar, and the bottom of the pad plate has a notch that corresponds to the position of the pad and fits in shape.

[0007] Furthermore, it also includes crossbars, and several trapezoidal holes are spaced apart on the four sides of the tray body, with crossbars installed in each trapezoidal hole.

[0008] Furthermore, it also includes spring clips, with spring clips embedded in each leg, and the spring clips separate the upper rigid support section and the lower elastic buffer section of the leg.

[0009] Furthermore, the tray body has several vertically penetrating drainage holes on its surface.

[0010] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses folding railing units on the front and rear sides to form a surrounding space for the powder bag that is in direct contact with the bottom of the tray. The baffles abut against the front and rear edges of the bottom of the powder bag, effectively limiting its sliding displacement. Combined with the pads on the tray to enhance friction, it reduces the sliding phenomenon caused by slight shaking or tilting, effectively avoiding the problem of the powder bag on the bottom of the tray sliding and causing the powder bag on the top layer to swing and slip off.

[0011] 2. The railing of this utility model can be folded, stored and stacked, improving space utilization and ease of operation. The folding railing can be folded horizontally through a linkage mechanism. After folding, the top of the railing is flush with the table surface, which does not affect subsequent operations and pallet stacking. When stacking, the groove at the bottom of the upper pallet pad precisely fits into the lower pallet pad block. Combined with the forklift clearance of the support legs, it not only ensures stacking stability but also facilitates overall forklift handling, improving work efficiency.

[0012] 3. This utility model uses a crossbar and trapezoidal holes to cooperate, which can help fix the powder bag with straps. The spring pieces in the legs separate the rigid support section and the elastic buffer section, which can not only ensure the stability of the support, but also absorb the impact and enhance the fixing effect in specific scenarios.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] A powder bag transfer tray, such as Figure 1-4 As shown, the pallet includes a pallet body 1, a pad 21, a rotating rod 3, a stop bar 4, and a rotating shaft 41. The pallet body 1 consists of a platform and multiple legs 2 integrally formed with the platform. A forklift clearance is formed between adjacent legs 2 on the same side, which facilitates the insertion of forklift forks, thereby enabling the pallet to be picked up and handled as a whole. This ensures that the pallet can cooperate stably with the forklift during transportation, improving the convenience of transportation. A pad 21 is provided laterally between the legs 2 on the front and rear sides. The pad 21 is fixedly connected to the legs 2, which can enhance the... The structural strength of the bottom of the pallet body 1 prevents the support legs 2 from deforming under heavy pressure, while providing more stable support for the entire pallet. Folding railing units are provided on both the front and rear sides of the platform. Each folding railing unit includes: multiple parallel rotating rods 3, the first end of which is rotatably connected to the side of the platform. This rotatable connection allows the rotating rods 3 to rotate around the side of the platform, providing a basis for the unfolding and folding of the railing; and multiple rotating shafts 41, each fixedly installed at the second end of a rotating rod 3. The rotating shafts 41 are fixedly connected to the rotating rods 3. This design ensures that there is no relative rotation between the two, guaranteeing the stability of the hinged structure between the stop bar 4 and the rotating rod 3. The stop bar 4 is hinged to multiple rotating rods 3 on the same side via a rotating shaft 41 to form a folding linkage mechanism. Through this hinged method, when the rotating rod 3 or the stop bar 4 is rotated, the multiple rotating rods 3 can move synchronously under the drive of the stop bar 4, realizing the overall unfolding or folding of the railing. The stop bar 4 is equipped with a locking mechanism, which is used to lock the unfolding angle of the stop bar 4 relative to the rotating rod 3. By locking the unfolding angle, it can be ensured that the railing remains stable in the unfolded state. The system reliably blocks the powder bags placed on the pallet, preventing them from sliding off the front and rear sides of the pallet during transport. The rotating rod 3, the stop bar 4, and the rotating shaft 41 together form a horizontally folding protective railing structure. When the stop bar 4 is folded, its top is on the same horizontal plane as the platform of the pallet body 1. This design ensures that the railing does not protrude above the platform after folding, saving storage space and preventing the folded railing from obstructing the placement of powder bags or the stacking of pallets, while maintaining the flatness of the pallet surface.

[0021] like Figure 1-4As shown, the locking mechanism includes a pull rod 5, a spring 51, and a stop block 52, wherein: at least one rotating shaft 41 has a locking hole 401 radially opened; a pull rod 5 is slidably disposed inside the stop rod 4, and a stop block 52 adapted to the locking hole 401 is fixedly disposed at the end of the pull rod 5, the sliding of the pull rod 5 provides a moving path for the stop block 52 to engage or disengage from the locking hole 401; a spring 51 is sleeved on the outer periphery of the pull rod 5, and the two ends of the spring 51 abut against the flange of the pull rod 5 and the inner wall of the stop rod 4, respectively, and the elastic force of the spring 51 can provide continuous support to the stop block 52. The thrust ensures that the insert 52 can be stably fitted into the locking hole 401 when the lever 5 is not pulled by an external force; the insert 52 maintains the fitted state with the locking hole 401 under the elastic force of the spring 51. This fitted state can fix the relative angle between the stop bar 4 and the rotating bar 3, thereby locking the unfolding angle of the railing. When the railing needs to be folded, simply pull the lever 5 to drive the insert 52 to compress the spring 51 and disengage from the locking hole 401. After unlocking, the angle between the stop bar 4 and the rotating bar 3 can be flexibly adjusted, which facilitates the folding operation of the railing.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a pad block 22. The pad block 22 is provided on the table surface of the pallet body 1 and on one side of the top of the baffle. The bottom of the pad plate 21 has a notch that corresponds to the position of the pad block 22 and fits in shape for stacking. When multiple pallets need to be stacked, the notch at the bottom of the pad plate 21 of the upper pallet can be precisely fitted into the pad block 22 of the lower pallet. Through this fitting structure, the stacked pallets can be effectively prevented from sliding relative to each other, ensuring the stability of the stack, while making reasonable use of space and reducing the floor space occupied during storage.

[0023] Before transferring the powder bag, unfold the protective railing. The operator can pull the lever 5 to compress the spring 51 and disengage the insert 52 from the locking hole 401, thus releasing the angle lock between the stop bar 4 and the rotating rod 3. Then, rotate the rotating rod 3. Since the first end of the rotating rod 3 is rotatably connected to the side of the tray body 1, the rotating rod 3 will rotate upward around the connection point, simultaneously driving the stop bar 4, which is hinged through the rotating shaft 41, to move synchronously. Under the linkage of the rotating rod 3 and the stop bar 4, the entire folding railing unit gradually unfolds. When the railing unfolds to the appropriate angle, release the lever 5. The spring 51 pushes the lever 5 back to its original position under the elastic force, so that the insert 52 is re-embedded into the corresponding locking hole 401, thereby locking the relative angle between the stop bar 4 and the rotating rod 3. Next, the powder bags are placed steadily on the platform of tray body 1. During placement, the bottom layer of powder bags that is in contact with the platform first makes contact with the platform. The front and back sides of the bags are then inserted along the inner side of the protective railing formed by the front and back rotating rods 3 and the stop rods 4. The railing forms a surrounding locking space from the front and back sides of the powder bags, allowing the bottom of the powder bags to be precisely positioned on the platform under the limit of the railing, achieving an embedded placement. At this time, the protective railing formed by the front and back rotating rods 3 and the stop rods 4, although only two in number and relatively low in height when unfolded, can form a stable locking position for the bottom layer of powder bags that is in contact with the platform from the front and back sides. The stop rods 4 hold the front and back edges of the bottom of the powder bags, limiting the displacement of the powder bags in the front and back directions. At the same time, the pads 22 on the platform provide slight lifting support for the powder bags from below, increasing the friction between the powder bags and the platform. This, combined with the locking function of the railing, prevents the powder bags in contact with the platform from sliding due to shaking or tilting during transportation, thus avoiding the powder bags from slipping. The pallet slides off the edge of the pallet, ensuring the stability of the bottom material during transport. When the transport is complete or the pallet needs to be folded for storage, pull lever 5 to release the lock and rotate lever 3 in the opposite direction. Lever 3 will cause stop lever 4 to fold towards the platform. Since lever 3, stop lever 4, and pivot 41 form a horizontal folding linkage mechanism, stop lever 4 will gradually approach the platform during folding. Finally, when stop lever 4 is fully folded, its top is at the same level as the platform of pallet body 1. At this time, the railing will not protrude from the platform, avoiding interference with subsequent operations and facilitating pallet stacking. When stacking pallets, the notched bottom of the pad 21 of the upper pallet precisely fits into the pad block 22 on the platform of the lower pallet and the top of the stop lever. This structural cooperation ensures the stability of multiple pallets when stacked, preventing the stacked pallets from shifting or tipping over. At the same time, the forklift clearance between the legs 2 facilitates the overall handling or loading and unloading of stacked pallets by forklifts and other equipment, improving work efficiency. In addition, the pad 21 not only enhances the structural strength of the bottom of the pallet, but also provides a stable support surface for the pallet above when stacking. Together with the pad block 22 and the notch, it ensures the reliability of the stacking state. The pad block 22 on the table can also play a certain anti-slip role when placing powder bags, further improving the stability of the powder bags on the pallet.

[0024] Before transferring the powder bags, the protective railing is first unfolded. The operator can pull the lever 5 to compress the spring 51 and disengage it from the locking hole 401, thus releasing the angle lock between the stop bar 4 and the rotating rod 3. Then, the rotating rod 3 is rotated. Since the first end of the rotating rod 3 is rotatably connected to the side of the tray body 1, the rotating rod 3 will rotate upward around the connection point, driving the stop bar 4, which is hinged through the rotating shaft 41, to move synchronously. Under the linkage of the rotating rod 3 and the stop bar 4, the entire folding railing unit gradually unfolds. Once the railing is extended to the appropriate angle, release the lever 5. The spring 51, under its elastic force, pushes the lever 5 back to its original position, causing the insert 52 to re-embed into the corresponding locking hole 401, thereby locking the relative angle between the stop bar 4 and the rotating bar 3. At this time, multiple powder bags are laid flat and orderly on the table surface of the tray body 1. The bottom layer of powder bags in contact with the table surface, especially the powder bags near the lever, slides along the inner side of the protective railing formed by the rotating bar 3 and the stop bar 4 on both sides. This allows the railing to form a surrounding locking space from both sides of the powder bags, ensuring that the bottom of the powder bags is precisely positioned on the corresponding position on the table surface under the limit of the railing, achieving an embedded placement state.

[0025] The purpose of the folding guardrail is primarily to stabilize the powder bags that are in direct contact with the work surface at the bottom. On one hand, the low-height protective structure formed by the rotating rods 3 and the stop bars 4 on both the front and rear sides, although consisting of only two guardrails and limited in height when unfolded, effectively provides limiting support to the front and rear edges of the bottom powder bags. The stop bars 4 abut against the front and rear sides of the bottom of the powder bags, restricting their sliding displacement on the work surface and effectively reducing slippage caused by slight shaking or tilting. On the other hand, when stacking powder bags, an embedded placement method is used, making reasonable use of the folding guardrail to further improve the stability of the powder bags. When the transfer operation is completed or the storage tray needs to be folded, pull the lever 5 again to release the lock, and rotate the rotating rod 3 in the opposite direction. The rotating rod 3 will drive the stop bars 4 to fold towards the work surface. Since the rotating rod 3, the stop bars 4, and the rotating shaft 41 form a horizontal folding linkage mechanism, the stop bars 4 will gradually approach the work surface during the folding process. When the lever 4 is fully folded, its top is on the same level as the table surface of the tray body 1, which will not protrude and interfere with subsequent operations, and will facilitate the stacking and storage of the tray.

[0026] When pallets are stacked, the notched groove at the bottom of the upper pallet's base plate 21 precisely engages with the pad blocks 22 on the lower pallet's platform and at the top of the stop bar. This structural cooperation ensures the stability of multiple pallets stacked together, preventing them from shifting or tipping over. Simultaneously, the forklift clearance between the legs 2 facilitates the overall handling or loading / unloading of stacked pallets by forklifts and other equipment, improving operational efficiency. Furthermore, the base plate 21 not only enhances the structural strength of the pallet's bottom but also provides a stable support surface for the upper pallet during stacking, working in conjunction with the pad blocks 22 and the notched groove to ensure the reliability of the stacked state. The pad blocks 22 on the platform also provide some anti-slip properties when placing powder bags, further improving the stability of the powder bags on the pallet.

[0027] Example 2

[0028] Based on Example 1, such as Figure 1 and Figure 4 As shown in the figure, it also includes a crossbar 6. Several trapezoidal holes 601 are spaced apart on the four sides of the pallet body 1. The size of the trapezoidal holes 601 gradually decreases from the outside to the inside. The two ends of the crossbar 6 are fixedly connected to the opposite inner walls of the trapezoidal holes 601, so that the crossbar 6 is stably mounted inside the trapezoidal holes 601 and does not protrude from the side of the pallet body 1. This structure allows the crossbar 6 to provide a reliable support point for the strapping. When it is necessary to further fix the powder bag on the pallet, the strapping can pass through the trapezoidal holes 601 and wrap around the crossbar 6. The shape of the trapezoidal holes 601 restricts the strapping from slipping laterally during the insertion process. At the same time, the crossbar 6 provides effective support for the strapping. Together with the railings on the front and rear sides, it can assist in fixing the powder bag from multiple directions in specific scenarios such as transportation bumps, enhance the overall fixing effect, and prevent the powder bag from shifting due to insecure fixing.

[0029] like Figure 1 It also includes spring clips. Each leg 2 is embedded with a spring clip. The edge of the spring clip is tightly fitted and fixedly connected to the inner wall of the leg 2, so that it will not loosen inside the leg 2. The spring clip divides the leg 2 into an upper rigid support section and a lower elastic buffer section. The upper rigid support section can maintain the stable support performance of the leg 2 on the table surface of the pallet body 1, ensuring that the table surface will not undergo excessive deformation when carrying powder bags. The lower elastic buffer section absorbs external impact force through the elastic deformation of the spring clip when the pallet comes into contact with the ground during placement or transportation, reducing the impact of vibration on the powder bags on the table surface. At the same time, the setting of the spring clip can also enhance the overall structural toughness of the leg 2, preventing the leg 2 from breaking due to long-term stress or impact.

[0030] In addition, such as Figure 1 , Figure 2 and Figure 4As shown, the tray body 1 has several vertically penetrating drainage holes 201 on its surface. These drainage holes 201 are evenly distributed on the surface. When the powder bag is damaged and causes powder leakage, or when rainwater or stains accumulate on the surface, the leaked powder, rainwater, and stains can be discharged from the surface in a timely manner through the drainage holes 201, preventing them from accumulating on the surface and affecting the stability of the powder bag, and avoiding residual powder or liquid from making the surface slippery.
