Description

Technical Field

[0001] This utility model relates to the field of welding frame technology for logistics conveying, specifically a welding frame structure for logistics conveying equipment. Background Technology

[0002] The welded frame of logistics conveying equipment is an important part of the logistics conveying system. The welded frame can support the logistics conveying equipment and facilitate its operation. The welded frame has good load-bearing capacity and bending strength. However, in use, traditional welded frames are not convenient for preventing the stacking of items according to their height. This can lead to unstable conveying and falling of items when they are stacked too high, thus affecting the stability of the conveying process.

[0003] To overcome the above-mentioned defects, the existing technology (Chinese patent with announcement number CN220617272U, announcement date March 19, 2024) provides a modular logistics conveyor frame for logistics transportation, including a base logistics sorting and transportation frame. A hanging beam is welded and fixed above the logistics sorting and transportation frame, and a logistics sorting baffle is provided below the hanging beam. A logistics sorting conveyor belt is bolted to the middle of the logistics sorting baffle. A position adjustment conveyor belt is provided to the right of the logistics sorting conveyor belt, and a logistics transportation baffle is provided below the right side of the position adjustment conveyor belt. A logistics conveyor frame body is welded and fixed below the logistics transportation baffle. A fixing pipe is welded and fixed to the middle of the logistics conveyor frame body, and a logistics transportation baffle is bolted below the fixing pipe. The logistics transportation baffle is bolted to the upper and lower sides of the logistics conveyor frame body. It has the advantages of convenient operation, good protection of logistics items, and good logistics transportation effect.

[0004] The aforementioned mechanism protects logistics items by using five or six transport baffles on both sides. However, in actual use, it does not provide sufficient protection for stacked transport items, which can easily cause them to fall during transport. Utility Model Content

[0005] The purpose of this utility model is to provide a welding frame structure for logistics conveying equipment, so as to solve the problem mentioned in the background art that traditional welding frames are not convenient to prevent the stacking of items according to the height of the conveyed items, which leads to the instability of the conveying of items and the resulting fall when the items are stacked too high during the conveying process, thus affecting the stability of the items during the conveying process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding frame structure for logistics conveying equipment, including a first mounting frame, a second mounting frame being internally connected to the first mounting frame, and a conveyor belt being provided at the upper end of the second mounting frame; a fixing box being provided at the upper end of the side of the first mounting frame, and an anti-stacking mechanism for preventing items from stacking being provided inside the fixing box, the anti-stacking mechanism including a connecting spring, the connecting spring being provided inside the fixing box, and an adjusting plate being provided at the bottom end of the connecting spring; fixing blocks being provided at both the front and rear sides of the first mounting frame, and a limiting mechanism for locking the position between the first mounting frame and the second mounting frame being provided on the outer side of the fixing blocks.

[0007] Furthermore, a top plate is provided above the fixed box, and a servo motor is provided at the top of the top plate. The output end of the servo motor is equipped with a threaded rod through a sprocket transmission mechanism, and the outer side of the threaded rod is threadedly connected to the fixed box. The adjusting plate is rotatably connected to the threaded rod.

[0008] Furthermore, the adjusting plate and the fixed box are connected by a connecting spring to form an elastic structure, and the adjusting plate passes through and extends to the outside of the connecting spring.

[0009] Furthermore, the top of the fixed box is provided with a lubricating oil storage soft bag, and the top of the lubricating oil storage soft bag is provided with a compression plate, which is located at the bottom of the top plate. The two sides of the lubricating oil storage soft bag are connected to oil nozzles through hoses, and the positions of the oil nozzles and the threaded rod correspond to each other.

[0010] Furthermore, both sides of the bottom end of the extrusion plate are provided with return springs, and the extrusion plate and the fixed box form an elastic structure through the return springs.

[0011] Furthermore, the limiting mechanism includes a hinge rod, which is hinged to both ends of the conveyor belt, and the hinge rod is sleeved on the outside of the fixed block.

[0012] Furthermore, a locking block is installed at the top of the hinge rod via a limiting spring, and both the top of the hinge rod and the fixing block are provided with a locking groove that matches the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The output of the servo motor rotates and drives the sprocket transmission mechanism to rotate, which in turn drives the threaded rods at the bottom of the top plate to rotate. When the threaded rods rotate, they move downward, which pushes the adjusting plate inside the fixed box downward. The distance between the adjusting plate and the conveyor belt is changed, so that items that are stacked too high are pushed down to the rear end of the conveyor belt for further transport, thus effectively preventing items from falling due to shaking when stacked too high.

[0015] Furthermore, as the top plate moves downward, it presses down on the extrusion plate, thereby squeezing the lubricating oil storage bladder at the bottom of the extrusion plate and causing the lubricating oil inside the storage bladder to be discharged. The lubricating oil inside the storage bladder is output through the hose and the nozzle and sprayed evenly onto the surface of the threaded rod, thus enabling the threaded rod to move more smoothly when rotating and moving downward.

[0016] Furthermore, the elasticity of the return spring can assist in the repositioning of the extrusion plate, so that the lubricating oil storage bladder will be reshaped synchronously by the extrusion plate after being pressed, which facilitates repeated pressing of the lubricating oil storage bladder and spraying of lubricating oil.

[0017] 2. The hinge rod is sleeved on the outside of the fixed block, and then the locking block is passed through the hinge rod and engaged with the fixed block, thereby fixing the position between the hinge rod and the fixed block, thus restricting the position between the first mounting frame and the second mounting frame, and preventing the second mounting frame from shifting position during the transport of items.

[0018] Furthermore, the shape of the locking block allows for better engagement with the slot, locking the hinge rod and the fixing block in place. Simultaneously, the slot at the bottom of the hinge rod engages with the fixing block. The hinge rod is hinged to the second mounting bracket, allowing the hinge rod to select a suitable fixing block and engage with it, increasing flexibility during use. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem that traditional welding frames are inconvenient to prevent item stacking based on the height of the conveyed items, leading to instability and item falls during transport when items are stacked too high, thus affecting the stability of the conveyed items. This welding frame structure for logistics conveying equipment discloses an anti-stacking mechanism, including a first mounting frame 1, with a second mounting frame 2 internally connected to it. A conveyor belt 3 is mounted on the upper end of the second mounting frame 2. A fixing box 4 is located on the upper side of the first mounting frame 1, and the fixing box 4 contains an anti-stacking mechanism. An anti-stacking mechanism for preventing items from stacking includes a connecting spring 5, which is located inside a fixed box 4. An adjusting plate 6 is located at the bottom of the connecting spring 5. A top plate 13 is located above the fixed box 4, and a servo motor 8 is located at the top of the top plate 13. A threaded rod 7 is installed at the output end of the servo motor 8 through a sprocket transmission mechanism. The outer side of the threaded rod 7 is threadedly connected to the fixed box 4. The adjusting plate 6 is rotatably connected to the threaded rod 7. The adjusting plate 6 and the fixed box 4 form an elastic structure through the connecting spring 5, and the adjusting plate 6 passes through and extends to the outside of the connecting spring 5.

[0028] In this example, the position between the first mounting frame 1 and the second mounting frame 2 is fixed by a limiting mechanism. Then, the items to be conveyed are placed on the surface of the conveyor belt 3 for conveying. The logistics conveying equipment can be installed using the second mounting frame 2, and the detection components can be installed using the first mounting frame 1, thus facilitating stable conveying of items. During the conveying process, items may stack up during loading, which could lead to unstable stacking and falling, resulting in damage. The output of the servo motor 8 rotates and drives the sprocket transmission mechanism to rotate, causing the threaded rods 7 at the bottom of the top plate 13 to rotate. When the threaded rods 7 rotate, they move downward, which pushes the adjusting plate 6 inside the fixed box 4 downward. The distance between the adjusting plate 6 and the conveyor belt 3 is changed, so that items with excessive stacking height are pushed down to the rear end of the conveyor belt 3 for conveying, effectively preventing items from falling due to shaking after being stacked too high, and increasing the applicability during use.

[0029] Example 2: Figure 1 , Figure 2 and Figure 3 The technical solution shown addresses the potential jamming issue between the threaded rod 7 and the top plate 13 during anti-stacking protection when adjusting the height of the adjusting plate 6. The welded frame structure for the logistics conveying equipment discloses a spraying mechanism. A lubricating oil storage pouch 9 is located at the top of the fixed box 4, and a pressing plate 10 is located at the top of the lubricating oil storage pouch 9. The pressing plate 10 is positioned at the bottom of the top plate 13. Oil nozzles 12 are connected to both sides of the lubricating oil storage pouch 9 via flexible hoses, and the positions of the oil nozzles 12 and the threaded rod 7 correspond to each other. Return springs 11 are located on both sides of the bottom of the pressing plate 10, and the pressing plate 10 and the fixed box 4 form an elastic structure through the return springs 11.

[0030] In this example, when the top plate 13 moves downward, it presses the extrusion plate 10, thereby squeezing the lubricating oil storage bladder 9 at the bottom of the extrusion plate 10 and causing the lubricating oil inside the lubricating oil storage bladder 9 to be discharged. The lubricating oil inside the lubricating oil storage bladder 9 is output through the hose and the oil nozzle 12 and sprayed evenly on the surface of the threaded rod 7, so that the threaded rod 7 can move more smoothly when rotating and moving downward, avoiding jamming. The elastic force of the return spring 11 can assist the extrusion plate 10 in repositioning, so that the lubricating oil storage bladder 9 will be repositioned synchronously by the extrusion plate 10 after being pressed, which is convenient for repeated pressing of the lubricating oil storage bladder 9 and spraying of lubricating oil.

[0031] Example 3: Figure 1 , Figure 5 and Figure 6The technical solution shown addresses the problem of insufficient splicing between the first mounting frame 1 and the second mounting frame 2, which can easily lead to positional shifts. The welded frame structure for the logistics conveying equipment discloses a limiting mechanism. Fixing blocks 15 are provided on the sides of both the front and rear ends of the first mounting frame 1, and a limiting mechanism for locking the position between the first mounting frame 1 and the second mounting frame 2 is provided on the outer side of the fixing blocks 15. The limiting mechanism includes a hinge rod 14, which is hinged to both ends of the conveyor belt 3 and sleeved on the outside of the fixing blocks 15. A locking block 16 is installed at the top of the hinge rod 14 via a limiting spring 18, and both the top of the hinge rod 14 and the fixing blocks 15 have slots 17 that match the locking blocks 16.

[0032] In this example, the position between the first mounting bracket 1 and the second mounting bracket 2 is adjusted, and then the hinge rod 14 is fitted onto the outside of the fixing block 15. Then, the locking block 16 passes through the hinge rod 14 and engages with the fixing block 15, thereby fixing the position between the hinge rod 14 and the fixing block 15. This restricts the position between the first mounting bracket 1 and the second mounting bracket 2, preventing the second mounting bracket 2 from shifting during the transport of items and increasing stability during use. The shape of the locking block 16 allows for better engagement with the slot 17, locking the hinge rod 14 and the fixing block 15 in place. Simultaneously, the slot at the bottom of the hinge rod 14 engages with the fixing block 15. The hinge between the hinge rod 14 and the second mounting bracket 2 allows the hinge rod 14 to select a suitable fixing block 15 and engage with it, increasing flexibility during use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
