Description

Technical Field

[0001] This utility model relates to the technical field of foam plastic sheet production and conveying equipment, and in particular to a multi-segment flexible chain plate foam plastic sheet conveying line. Background Technology

[0002] In the production process of foam plastic sheets (such as EPS and XPS sheets), the molded sheets need to be transferred between different workstations (such as curing, cutting, stacking, and packaging) using various conveyor equipment. The performance of the conveyor line directly affects the efficiency, layout, and product quality of the entire production line.

[0003] Currently, the conveying equipment commonly used in the industry is mainly linear chain conveyors or roller conveyors. While these devices meet basic conveying needs to a certain extent, they still have many limitations in practical applications: existing conveyor belts or roller lines are usually rigid, integral structures; once installed, their conveying path is fixed. This results in a rigid production line layout, making it impossible to flexibly arrange curves, bends, or branch paths according to workshop space conditions or process changes, severely limiting the optimization of production planning. Foamed plastic sheets are lightweight and easily worn. In long-distance conveying, traditional single-point drive methods are prone to uneven or asynchronous chain tension, causing the sheets to shift, slide, or even tip over on the conveyor belt. Especially in areas requiring turning, the lack of effective transition and guiding mechanisms makes the sheets highly susceptible to collisions and scratches with equipment edges, resulting in edge damage or surface scratches and increased scrap rates. Existing conveyor lines typically only have simple straight-line transmission functions and lack diversion capabilities. When producing boards of different specifications or transporting boards to different workstations, it is often necessary to configure multiple independent conveyor lines or rely on manual intervention. This not only increases equipment costs and floor space but also reduces production efficiency and automation.

[0004] Therefore, there is an urgent need in this field for a new type of conveyor line that can solve the above problems, achieve flexible layout, stable conveying and intelligent diversion, so as to meet the high-efficiency and high-quality requirements of modern foam plastic board production.

[0028] Reference Figure 1According to a first aspect of this utility model, a multi-segment flexible chain plate type foam plastic sheet conveyor line is characterized by comprising an adjustable-width inlet section 100, a straight conveying section 200, a curved conveying section 300, and an intermediate transition section 400. The conveyor line is modularly designed with adjustable-width inlet section 100, straight conveying section 200, curved conveying section 300, and intermediate transition section 400, each segment of which can be combined as an independent module. This design completely overcomes the shortcomings of traditional fixed conveyor lines that cannot adapt to complex production layouts. Users can freely assemble various layouts such as straight lines and curves according to the actual space and process requirements of the workshop, greatly improving the equipment's adaptability to different application scenarios.

[0029] The adjustable-width inlet section 100 includes a first flexible chain plate 111, a first chain 121, a first sprocket set 131, and a first drive mechanism 141. The first sprocket set 131 is respectively disposed at both ends of the inlet section 100. The first chain 121 is engaged with the first sprocket set 131. The first flexible chain plate 111 is connected to the first sprocket set 131 through the first chain 121. The first sprocket set 131 is driven by the first drive mechanism 141. The inlet section 100 is provided with at least two output channels 152 and a channel selection mechanism 150. The at least two output channels 152 and the channel selection mechanism 150 provided in the inlet section 100 are a core advantage of this embodiment. It enables a single conveyor line to have a diversion function, and can automatically select to enter different subsequent conveying paths (such as going to different processing stations, packaging areas, or warehouses) according to production instructions (such as different specifications and batches of boards), realizing the automation and intelligence of the production process and laying the foundation for building a flexible production system.

[0030] A linear conveying section 200 is connected to a channel of the inlet section 100. The linear conveying section 200 includes a second flexible chain plate 211, a second chain, a second sprocket set, and a second drive mechanism. The second sprocket set is respectively disposed at both ends of the linear conveying section 200. The second chain is wound around and engaged with the second sprocket set. The second flexible chain plate 211 is connected to the second sprocket set through the second chain. The second sprocket set is driven by the second drive mechanism.

[0031] The curved conveyor section 300 is connected to another channel of the straight conveyor section 200. The curved conveyor section 300 includes a third flexible chain plate 311, a third chain, a third sprocket set, and a third drive mechanism. The third sprocket set is respectively disposed at both ends of the curved conveyor section 300. The third chain is wrapped around and meshed with the third sprocket set. The third flexible chain plate 311 is connected to the third sprocket set through the third chain. The third sprocket set is driven by the third drive mechanism.

[0032] An intermediate transition section 400 connects the straight conveying section 200 and the curved conveying section 300. The intermediate transition section 400 includes a fourth flexible chain plate 411, a fourth chain 421, a fourth sprocket set 431, and a fourth drive mechanism 441. The fourth sprocket set 431 is respectively disposed at both ends of the intermediate transition section 400. The fourth chain 421 is engaged with the fourth sprocket set 431. The fourth flexible chain plate 411 is connected to the fourth sprocket set 431 through the fourth chain 421. The fourth sprocket set 431 is driven by the fourth drive mechanism 441.

[0033] Each of the aforementioned conveying sections employs an independent drive mechanism (first, second, third, and fourth drive mechanisms 441) to drive its corresponding sprocket assembly and flexible chain plate. This independent drive design ensures independent and precise control of the conveying speed of each section, avoiding problems such as asynchrony and uneven chain tension that may arise from long-distance single-drive systems. Combined with the optimized connection design of the intermediate transition section 400, it ensures that the sheet material is very stable throughout the entire process of straight conveying, turning transitions, and diversion switching, greatly reducing the risk of sheet material deviation, slippage, jamming, or even tipping, effectively protecting the edges and surface integrity of fragile products like foam plastic sheets, and reducing the scrap rate. In addition, the core transmission structure (sprocket assembly, chain, and drive mechanism) of each conveying section is located at both ends, resulting in a compact structure, uniform force distribution, and reliable operation. The modular design also means that if a section (such as a straight section) malfunctions, targeted repairs and maintenance can be carried out without stopping the entire conveying system, significantly improving the maintainability and overall utilization of the equipment.

[0034] This technical solution, through its ingenious modular and independent drive design, successfully integrates numerous advantages such as flexible layout, intelligent diversion, stable conveying, easy maintenance, and easy expansion. It effectively solves the various problems mentioned in the background technology and significantly improves the automation level, conveying efficiency, and quality of foam plastic board production.

[0035] According to an embodiment of this utility model, a multi-segment flexible chain plate foam plastic sheet conveying line has at least the following beneficial effects: By setting an adjustable inlet segment 100 with at least two output channels 152 and a channel selection mechanism 150, and modularly combining it with independent straight conveying segments 200, curved conveying segments 300, and intermediate transition segments 400, a highly flexible and adaptable conveying system is constructed. Each conveying segment adopts an independent flexible chain plate, chain, sprocket assembly, and drive mechanism, which not only achieves stable and efficient conveying of foam plastic sheets in complex paths (including straight lines, curves, and turning transitions), effectively preventing sheet offset, jamming, or damage, but also allows the modular design to freely expand and reorganize the entire line layout according to actual production needs, greatly improving the equipment's versatility for different production scenarios and sheet specifications, thereby significantly improving production efficiency and conveying reliability.

[0036] According to some embodiments of this utility model, the two output channels 152 are arranged in a herringbone pattern. The output channel 152 selection mechanism 150 is located above the center of the output channel 152 and includes a gantry frame 151 spanning the output channel 152 and a lifting mechanism located in the middle of the gantry frame 151. The lifting mechanism includes a lifting cylinder 153 inverted and installed in the middle of the gantry frame 151, and a V-shaped diverter 154 connected to the movable end of the lifting cylinder 153. The V-shaped diverter 154 includes a V-shaped body and two intersecting guide bars 155 detachably installed on the V-shaped body. The herringbone arrangement of the output channels 152 matches the structure of the V-shaped diverter 154 and the guide bars 155. The unique shape of the V-shaped diverter 154 naturally guides the sheet material from the inlet section 100 to the guide strips 155 on both sides. The intersecting structure of the guide strips 155 ensures that the sheet material is smoothly and accurately guided to one of the two preset channels the moment it contacts the diverter. The diversion action is completed in one go, greatly improving the diversion efficiency and accuracy, and effectively avoiding jamming or congestion of the sheet material at the diversion point due to unclear guidance. In addition, the channel selection mechanism 150 uses a gantry frame 151 as a support base. Its arrangement across the channel provides an extremely stable support structure 600, ensuring that the entire diversion mechanism operates smoothly without shaking during operation. The V-shaped diverter 154 is driven to move up and down by an inverted lifting cylinder 153 to switch the diversion mode (i.e., divert or yield). This linear lifting motion is very stable and controllable. Compared with swing-type or push-plate type diversion mechanisms, it causes less impact and friction on the foam plastic sheet, effectively protecting the surface quality of the product. The guide strips 155 are detachably installed on the V-shaped body. This design allows users to easily replace guide bars 155 with different specifications and materials (such as different wear resistance or smoothness) according to the specifications (such as width and thickness) or materials of different plates, making one diversion mechanism adaptable to a variety of products and highly versatile. Furthermore, when guide bars 155 wear down due to long-term use, it is not necessary to replace the entire V-shaped diverter 154; only the worn guide bars 155 need to be replaced, significantly reducing subsequent maintenance costs and downtime. The entire diversion mechanism is integrated within the gantry 151, with a compact layout that does not occupy additional space. Its core operation relies solely on the single linear motion of the lifting cylinder 153. The control system is very simple and reliable; switching the diversion function can be achieved simply by controlling the extension and retraction of the lifting cylinder 153, reducing equipment manufacturing costs and failure rates.

[0037] According to some embodiments of this utility model, the first drive mechanism 141, the second drive mechanism, the third drive mechanism, and the fourth drive mechanism 441 all include a motor 161 and a reducer 162. The motor 161 is connected to the first sprocket set 131, the second sprocket set, the third sprocket set, and the fourth sprocket set 431 respectively through the reducer 162. The inlet section 100, the straight conveying section 200, the curved conveying section 300, and the intermediate transition section 400 are all equipped with independent "motor 161-reducer 162" drive units, which directly drive the sprocket set of their respective sections. This design allows for independent and precise control of the operating speed of each section. By coordinating the rotational speed of each motor 161 through the central control system, it is possible to ensure perfect speed matching of the sheet metal at the junction of sections, fundamentally eliminating problems such as asynchrony, pulling, accumulation, or uneven tension caused by a single long drive, and ensuring the smoothness and continuity of the entire conveying process. Each drive unit of the first drive mechanism 141, the second drive mechanism, the third drive mechanism, and the fourth drive mechanism 441 is only responsible for driving its own section, so that the layout of the conveyor line is no longer limited by the physical location of the power source, and can be arranged more freely and flexibly according to the workshop space. At the same time, distributed drive reduces power loss in long-distance transmission and improves the overall transmission efficiency. Finally, different conveying sections (such as the straight conveying section 200 and the curved conveying section 300 that requires turning power) have different operating resistance loads. Independent drive allows matching motors 161 and reducers 162 of different power for sections with different loads, achieving optimal power configuration, avoiding power redundancy, and precise load matching reduces abnormal wear of each drive unit, which helps to extend the service life of the entire conveying system.

[0038] According to some embodiments of this utility model, a support structure 600 is also included, disposed below the inlet section 100, the straight conveying section 200, the curved conveying section 300, and the intermediate transition section 400. A unified support structure 600 is configured for each of these independent modules—the inlet section 100, the straight conveying section 200, the curved conveying section 300, and the intermediate transition section 400—forming a stable underlying frame. This integrated support effectively resists vibrations generated during equipment operation and stresses transmitted between parts, preventing deformation, shaking, or sinking of the conveyor line due to insufficient support. It provides a fundamental guarantee for the stability of the entire conveying system under high load and long-term operation, ensuring conveying accuracy.

[0039] According to some embodiments of this utility model, the support structure 600 includes: support legs 610 for supporting corresponding conveying sections; and adjustable feet 620 disposed on the support legs 610 for adjusting the height of the support legs 610. By providing adjustable feet 620 at the bottom of each support leg 610, installation and commissioning personnel can easily rotate the feet to independently and precisely adjust the height of each support point. This function is crucial, as it effectively compensates for manufacturing tolerances and unevenness of the installation ground, ensuring that the conveying surfaces of all modules, including the inlet section 100, the straight conveying section 200, the curved conveying section 300, and the intermediate transition section 400, remain at the same horizontal level. This ensures smooth and seamless connections between sections, completely avoiding the risk of jamming, scratching, or falling of the conveyed plates due to height differences, laying a solid foundation for the stable operation of the entire system. The support legs 610 provide direct and stable rigid support for the conveying sections, forming a stable basic frame that effectively suppresses vibrations generated by the chain and motor 161 during equipment operation, preventing the entire line from swaying and ensuring conveying accuracy. Meanwhile, adjusting the foot cup 620 (usually a metal cup with a rubber pad or similar structure) to contact the ground can increase stability and also play a certain role in vibration reduction, reducing the transmission of equipment vibration to the ground, and also reducing the impact of ground vibration on the equipment itself.

[0040] The embodiments described above with reference to the accompanying drawings have been described in detail. However, the embodiments are not limited to those described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
