Description

Technical Field

[0001] This utility model relates to the field of beverage can conveying line technology, and in particular to a frame structure, conveying line unit and conveying line. Background Technology

[0002] In the field of aluminum can conveyor line technology, conveyor lines are typically composed of several independent conveyor line units. Each conveyor line unit includes two parallel side plates and multiple crossbeams connecting the side plates. Traditional conveyor line units use a bolted assembly structure, where mounting holes are made in the side plates, and end plates are welded to both ends of the crossbeams. The end plates are then connected to the side plates by bolts. This structure has the following drawbacks:

[0003] 1. Low assembly efficiency: Due to the large number of bolts, the assembly time is very long. Therefore, the individual parts of the conveyor line are not sent to the customer separately. Instead, the assembled conveyor line units are sent to the customer. When they arrive at the customer's location, each section of the conveyor line unit is assembled into a complete conveyor line. This method can save the subsequent transportation and installation time at the customer's location and meet the customer's requirements. However, for the production plant, there are problems of large assembly volume and long time consumption.

[0004] 2. Insufficient structural strength: Since the conveyor unit is assembled rather than welded, the connections between components rely solely on bolts. The bolt connections are not strong enough, and during hoisting and handling, the hoisting point is generally not precisely at the center of gravity of the conveyor unit, causing it to tilt and easily become twisted and deformed. Vibration during transportation also causes deformation. Upon reinstallation at the customer's site, adjustments must be made based on the deformation. If the deformation is significant, bolts need to be loosened, and the deformed beams and side plates re-corrected before reassembly, which is time-consuming and labor-intensive.

[0005] 3. High cost: In order to improve structural strength, the traditional Z-shaped crossbeam used to install aluminum profiles is inverted. Its upward wide surface is divided into two parts, each with bolt holes. The aluminum profile is fixed by two rows of bolts. The bolt usage is large, which increases the cost and the time spent installing the bolts. Utility Model Content

[0006] To address the problems of low assembly efficiency, insufficient strength, and high cost of traditional bolted conveyor lines, this utility model provides a frame structure, conveyor line unit, and conveyor line that optimizes the connection method through welding process and simplifies the beam structure, thereby improving factory pre-assembly efficiency, reducing bolt usage, strengthening structural strength, and reducing transportation deformation.

[0007] To achieve the above objectives, in a first aspect, this utility model provides a frame structure, including two side plates and at least two crossbeams. The crossbeams are welded and fixed between the two side plates. The crossbeams have a Z-shaped cross section, with the top width of the crossbeam being smaller than its bottom width. Positioning holes are provided on the side plates, and both ends of the crossbeams are provided with protrusions that are adapted to the positioning holes. The protrusions are engaged with the positioning holes.

[0008] Preferably, the length direction of the side plate is perpendicular to the length direction of the crossbeam.

[0009] Secondly, this utility model provides a conveyor line unit, including a butt welding plate and the above-mentioned frame structure, with butt welding plates fixed at both ends of the side plate, and butt welding holes provided on the butt welding plates.

[0010] Preferably, the crossbeam is divided into an aluminum profile support beam and a roller support beam. The aluminum profile support beam is located above the roller support beam. The top of the aluminum profile support beam has several bolt mounting holes along its length for installing aluminum profiles. A roller is installed on the roller support beam.

[0011] Preferably, the mating hole is an oblong hole.

[0012] Preferably, the length direction of the butt hole on the butt welding plate at one end of the side plate is consistent with the horizontal direction, and the length direction of the butt hole on the butt welding plate at the other end of the side plate is consistent with the vertical direction.

[0013] Thirdly, this utility model provides a conveyor line, including multiple conveyor line units as described above. The conveyor line units are arranged in a straight line, and two adjacent conveyor line units are connected by a bolt assembly. The bolt assembly includes a bolt and a nut. The bolt passes through the mating hole of the adjacent butt welding plate of the two adjacent conveyor line units and is threadedly connected to the nut.

[0014] Preferably, it also includes a butt-joint aluminum profile support beam, the butt-joint aluminum profile support beam has a Z-shaped cross section, the top width of the butt-joint aluminum profile support beam is smaller than its bottom width, and end plates are welded and fixed at both ends of the butt-joint aluminum profile support beam. The end plates are connected to the side plates by bolt assemblies. The side plates are provided with a first threaded connection hole corresponding to the bolt assembly, and the end plates are provided with a second threaded connection hole corresponding to the bolt assembly.

[0015] Preferably, the top width of the connecting aluminum profile support beam is greater than the top width of the crossbeam, and the top of the connecting aluminum profile support beam has two rows of bolt mounting holes for installing aluminum profiles along its length.

[0016] Preferably, the length direction of the side plate is perpendicular to the length direction of the crossbeam.

[0017] The beneficial effects of this technical solution are:

[0018] 1. The frame structure of the conveyor unit replaces the traditional bolt connection with welding technology, eliminating the risk of bolt loosening and falling off. The connection contact area is greatly increased, making the crossbeam and side plate form an integrated structure, which significantly improves the overall rigidity and deformation resistance of the conveyor unit, effectively resists the external forces generated by hoisting, handling and transportation vibration, and ensures the stability and reliability of the unit structure.

[0019] 2. Compared to the tedious process of installing a large number of bolts one by one, the welding method eliminates the need for complex hole alignment and thread tightening operations, reducing repetitive labor and significantly shortening the unit assembly time in the factory; at the same time, it avoids the on-site assembly process after the disassembled parts are transported, realizing modular pre-assembly of units, requiring only splicing on-site, which significantly improves the overall line installation efficiency.

[0020] 3. It reduces the use of bolts, nuts and other fasteners, thus lowering the cost of parts procurement; welding operations simplify the production process, reduce labor hours, and lower assembly costs; the increased structural strength reduces deformation and loss during transportation and use, lowers maintenance costs, and improves overall economic benefits.

[0021] 4. The welding process allows for precise control of component positions, ensuring overall unit dimensional accuracy, avoiding dimensional deviations caused by bolt connection gaps, reducing issues such as belt misalignment and component loosening, and ensuring the stability and reliability of the conveyor line operation.

Detailed Implementation

[0033] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] Please see Figures 8 to 10 The existing conveyor line unit uses a bolt 4 assembly structure. Mounting holes are made in the side plate 1, and end plates 3 are welded to both ends of the crossbeam 2. The end plates 3 are connected to the side plate 1 by bolts 4 passing through the mounting holes. The crossbeam 2 is divided into aluminum profile support beams 23 and roller support beams 24. Due to the low strength of the bolt 4 assembly, to improve the overall structural strength and the fixing strength of the aluminum profile 6, the aluminum profile support beam 23 is inverted, with its wide side facing upwards. The upward-facing side has two parts, both with bolt mounting holes 21. Two rows of bolts 4 are installed to fix the aluminum profile 6, resulting in an increase in the number of bolts 4 and increased installation time.

[0035] Please see Figures 1 to 7 This application provides a conveyor line, which includes multiple conveyor line units arranged in a straight line. Each conveyor line unit includes a butt welding plate 5 and a frame structure.

[0036] The frame structure includes two side plates 1 and at least two crossbeams 2. The length direction of the side plates 1 is perpendicular to the length direction of the crossbeams 2. The crossbeams 2 are welded and fixed between the two side plates 1. The crossbeams 2 have a Z-shaped cross section, with the top width of the crossbeam 2 being smaller than its bottom width. The side plates 1 have positioning holes 11, and both ends of the crossbeams 2 have protrusions 22 that fit into the positioning holes 11. The protrusions 22 engage with the positioning holes 11. Both ends of the side plates 1 are fixed with butt welding plates 5, and the butt welding plates 5 have butt holes 51.

[0037] Among them, the crossbeam 2 is divided into aluminum profile support beam 23 and roller support beam 24. The aluminum profile support beam 23 is located above the roller support beam 24. The top of the aluminum profile support beam 23 has several bolt mounting holes 21 for installing aluminum profiles 6 along its length direction. The roller support beam 24 is equipped with rollers.

[0038] The conveyor line unit provided in this embodiment adopts a welding method, which can ensure the strength and squareness of the conveyor line. Welding can be performed simply by opening a positioning hole 11 on the side plate 1 and then inserting the crossbeam 2 directly into the corresponding positioning hole 11.

[0039] The advantages of this are:

[0040] First, the work efficiency of assembly personnel in the factory has been improved, as they no longer need to install as many bolts.

[0041] Secondly, the strength of the conveyor unit is improved, and it is stronger than that of the conveyor unit assembled with bolts 4. The conveyor unit assembled with bolts 4 is only connected by bolts 4, while the crossbeam 2 and the side plate 1 in this embodiment are connected by peripheral welding. There are more welding connection points, and the deformation is lower. The independence of the conveyor unit is better, and the deformation is also very small when it is tilted and hoisted. When the conveyor unit is transported to the customer's site, the deformation is very small or there is basically no deformation, which reduces the on-site commissioning time.

[0042] During welding, approximately 70% of the connection between the crossbeam 2 and the side plate 1 is welded to avoid excessive welding that could cause component deformation. The area of ​​the welded joint is much larger than the connection area of ​​the bolt 4, thereby improving the overall connection strength of each component.

[0043] Due to the high strength of the welded structure, the crossbeam 2 can be made with the wide side facing down while ensuring overall strength. A row of bolt mounting holes 21 will be opened on the upward side, reducing the number of bolts 4 required for installing the aluminum profile 6 by half.

[0044] It's important to note that we don't transport parts in bulk because the on-site assembly work would be extensive and time-consuming. If parts were transported in bulk, the numerous types and complex classification of components would be time-consuming and labor-intensive, which customers generally wouldn't allow. Therefore, we now offer modular assembly. Modular assembly means that each conveyor line unit is treated as a module, and all conveyor line units are delivered to the site as a single module, making assembly much easier.

[0045] If the conveyor unit deforms or deviates significantly, the conveyor belt may run off-track. This could damage the frame or tear the conveyor belt, causing a large number of aluminum cans to tip over and become waste.

[0046] In this embodiment, two adjacent conveyor line units are connected by a bolt assembly, which includes a bolt 4 and a nut 7. The bolt 4 passes through the mating hole 51 of the adjacent butt welding plate 5 of the two adjacent conveyor line units and is threadedly connected to the nut 7.

[0047] By adopting a modular design, the conveyor line is divided into multiple independent conveyor line units. The factory can pre-assemble the conveyor line units, reducing the amount of on-site assembly work. The bolt assembly and the mating hole 51 are used to achieve quick splicing of adjacent units. The standardized connection method facilitates later maintenance. In case of failure, individual conveyor line units can be quickly disassembled and replaced, reducing downtime for maintenance.

[0048] In some embodiments, please refer to Figures 1 to 2 To improve the connection strength of the conveyor line unit, a docking support beam 8 is also provided. The cross-section of the docking support beam 8 is shaped like a "Z". The top width of the docking support beam 8 is smaller than its bottom width. Both ends of the docking support beam 8 are welded and fixed with end plates 3. The end plates 3 are connected to the side plates 1 by bolt assemblies. The side plates 1 have a first threaded connection hole 12 corresponding to the bolt assembly, and the end plates 3 have a second threaded connection hole 31 corresponding to the bolt assembly.

[0049] Specifically, the connecting beam 8 enhances the structural strength of the connection between adjacent conveyor line units, avoiding a decrease in overall stability due to weak stress at the splicing point of the conveyor line units; the setting of the first threaded connection hole 12 and the second threaded connection hole 31 facilitates the connection of two adjacent conveyor line units by the connecting beam 8; the Z-shaped structure of the connecting beam 8 balances strength and lightweight.

[0050] It should be noted that in some other embodiments, the docking support beam 8 can also be used as a component of the conveyor line unit. When transporting the conveyor line unit, the docking support beam 8 is already installed on the side plate 1.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 To facilitate the fixed connection of aluminum profiles 6 on two adjacent conveyor line units, the top width of the connecting beam 8 is greater than the top width of the crossbeam 2, and the top of the connecting beam 8 has two rows of bolt mounting holes 21 for installing aluminum profiles 6 along its length.

[0052] It should be noted that the widened top of the connecting beam 8 and the double-row bolt 4-hole design provide a larger contact area and stronger fixing force for the installation of aluminum profile 6, making it easier to fix the aluminum profile 6 on two adjacent conveyor line units.

[0053] In some embodiments, please refer to Figures 1 to 3To facilitate the connection of the two butt welding plates 5 together, the butt hole 51 is set as an oblong hole. The length direction of the butt hole 51 on the butt welding plate 5 at one end of the side plate 1 is consistent with the horizontal direction, and the length direction of the butt hole 51 on the butt welding plate 5 at the other end of the side plate 1 is consistent with the vertical direction.

[0054] It should be noted that the waist-shaped docking hole 51 provides lateral and longitudinal adjustment margins for the splicing of adjacent conveyor line units, which can effectively compensate for installation deviations caused by processing errors, uneven ground, or transportation deformation. The differentiated design in the horizontal and vertical directions allows for fine-tuning of the horizontal position to ensure mesh belt alignment during unit splicing, while also adapting to height differences, ensuring a smooth transition of the entire conveyor line and avoiding structural damage or operational jams caused by rigid connections.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
