Description

Technical Field

[0001] This utility model relates to the field of cement production and shipping facilities, and in particular to a conveyor belt docking assembly for cement production and shipping. Background Technology

[0002] The bagged cement shipping system is the final stage of the entire cement production process. It is a complete integrated equipment system that completes the collection, transfer, loading, and final shipment of bagged cement. Connecting the cement packaging process upstream and the logistics and transportation downstream, it is a core module ensuring the company's shipping efficiency. Its core function is to transfer and collect the finished bagged cement, packaged by each packaging machine, through multi-stage belt conveyors, turning and docking, and diversion guidance, ultimately loading it orderly onto freight vehicles or stacking it on transport pallets to complete the shipping process. Its operational efficiency and shipping adaptability directly affect the cement company's shipping capacity and market responsiveness.

[0003] Regarding the aforementioned technologies, the inventors believe that the packaging and shipping systems of most small and medium-sized cement enterprises in China are currently built in phases. Early plans only connect low-grade cement, such as M32.5 cement, with automated shipping channels for robotic loading and pallet palletizing. The high-grade cement production lines that were put into operation later did not reserve supporting channels, resulting in packaging units producing high-grade cement such as PO42.5 and PC42.5 being unable to connect to the automated shipping system. This not only causes idle capacity and low equipment utilization of high-grade production lines, but also fails to meet the growing demand for high-grade palletized cement in the construction market. There is a common pain point in the industry where capacity supply and market demand are mismatched.

[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the current problem of obstructed automated shipping of high-specification cement equipment, this utility model provides a belt coupling assembly for cement production and shipping.

[0006] The present invention provides a conveyor belt docking assembly for cement production using the following technical solution: A cement production conveyor belt docking assembly includes a low-standard packaging machine and a high-standard packaging machine arranged in parallel. The output end of the low-standard packaging machine is connected to an automated shipping channel, and the output end of the high-standard packaging machine is equipped with a clearing packaging machine. The clearing packaging machine is mounted on top of the low-standard packaging machine and is used to transfer the bagged cement output from the high-standard packaging machine to the low-standard packaging machine, so that the bagged cement conveyed on the high-standard packaging machine can be automatically shipped through the automated shipping channel connected to the output section of the low-standard packaging machine. The unblocking packaging machine, the high-standard packaging machine, and the low-standard packaging machine are all equipped with conveying units inside; The top of the unclogging and packaging machine is fixedly installed with a guide transfer structure, which guides the bagged cement conveyed on the unclogging and packaging machine to the low-standard packaging machine.

[0007] Preferably, the guiding and transferring structure includes an outer frame, an electric push rod, and a baffle; the bottom end of the outer frame is fixed to the top of the unblocking and packaging machine, and the two side legs of the outer frame are respectively rotatably connected to one end of the electric push rod and the baffle. The output end of the electric push rod is rotatably connected to the baffle, forming a rotatable angle-adjustable guiding structure. The bottom end of the baffle is set corresponding to the discharge end of the unblocking and packaging machine.

[0008] Preferably, the conveying unit includes several rotating rollers and a motor. A conveyor belt is fitted on the surface of the rotating rollers, and the motor is connected to any of the rotating rollers to drive the rotating rollers to rotate.

[0009] Preferably, side guard plates are fixedly installed on both sides of the unblocking and packaging machine. The side guard plates protrude from the surface of the conveyor belt to prevent the bagged cement from detaching from the belt during the conveying process.

[0010] Preferably, the output end of the high-standard packaging machine is fixedly equipped with a discharge chute, which is an inclined material guiding structure used to guide the bagged cement output by the high-standard packaging machine to fall smoothly into the unblocking packaging machine.

[0011] Preferably, the unblocking packaging machine is fixedly connected to a corner chute near the discharge end of the guiding and transfer structure. The corner chute is used to receive the bagged cement discharged from the guiding and transfer structure and guide it to the low-standard packaging machine. The low-standard packaging machine is provided with a rotating roller for receiving the bagged cement at the discharge position of the corner chute.

[0012] Preferably, the unblocking packaging machine and the conveying unit within the unblocking packaging machine are assembled from idle equipment materials that have been modified, dismantled, and recycled from the original pallet stacking system. The whole machine is arranged at an angle in the reserved gap area between the high-standard packaging machine and the low-standard packaging machine, without changing the main layout of the original conveying line and shipping system.

[0013] In summary, this utility model has the following beneficial technical effects: By adding a dredging packaging machine to connect the conveyor channels of high-grade packaging machines and low-grade packaging machines, high-grade cement that could only be shipped manually can now be directly connected to the automated shipping channel of the low-grade packaging machine. The single-shift shipping efficiency has increased from 120 tons to more than 380 tons, effectively reducing the cost of manual shipping. The capacity utilization rate of the high-grade packaging machine has increased from less than 45% before the transformation to more than 90%, effectively solving the problem of idle high-grade cement capacity and meeting the market's bulk demand for high-grade bagged pallet cement. By assembling the entire packaging machine and its core conveying components from idle equipment recycled after the original pallet palletizing system was modified and dismantled, there is no need to purchase a complete set of large equipment from scratch, nor to change the original factory building and the main layout of the conveyor line. The overall transformation cost is only 1 / 5 to 1 / 8 of that of building a new independent automated shipping line, which greatly reduces the financial threshold for enterprise technological transformation. At the same time, the transformation construction only requires the reserved space between equipment for installation, and the transformation cycle can be compressed to within 3 days. The construction can be completed during non-production periods without interrupting normal production and shipping, thus avoiding the production capacity loss caused by production stoppage due to transformation.

[0016] The following is in conjunction with the appendix Figure 1-3 This utility model will be described in further detail. Example 1

[0017] This utility model discloses a belt conveyor assembly for cement production and shipping, specifically for the application of the phased transformation of packaging and shipping systems in small and medium-sized cement enterprises in China. In the existing shipping system, the output end of the low-grade packaging machine 2 (M32.5 low-grade cement packaging machine) is pre-connected to the automated pallet palletizing and shipping channel, which can complete the automated loading, palletizing and shipping of bagged low-grade cement. The high-grade packaging machine 1 (PO42.5, PC42.5 high-grade cement packaging machine) that is newly built and put into operation later does not have a channel reserved for connection to the automated shipping system, and can only complete the shipping by manual loading. This results in the high-grade packaging machine 1 having idle capacity, low equipment utilization, and failing to meet the market demand for high-grade palletized cement.

[0018] Reference Figure 1 - Figure 2 The system includes a high-standard packaging machine 1, a low-standard packaging machine 2, and a dredging packaging machine 3. The dredging packaging machine 3 is mounted on top of the low-standard packaging machine 2, and is arranged at an angle in the reserved gap between the output end of the high-standard packaging machine 1 and the input end of the low-standard packaging machine 2. The modification utilizes existing site space and does not require changes to the main layout of the original conveyor line and shipping system. In this embodiment, the entire dredging packaging machine 3 and its internal conveying components are assembled from recycled idle equipment materials from the dismantling of the original pallet stacking system. The modification process does not require the purchase of new large-scale equipment, significantly reducing the technological upgrading investment costs for small and medium-sized cement enterprises and meeting the technological upgrading budget needs of small and medium-sized plants.

[0019] The packaging machines 3, 1, and 2 are all equipped with a conveying unit 4. The conveying unit 4 specifically includes a motor 401. The output end of the motor 401 is fixedly connected to a rotating roller 402 through a coupling. The two ends of the rotating roller 402 are rotatably connected to the inner wall of the frame of the corresponding packaging machine through bearings. The outer sides of multiple rotating rollers 402 are connected to a conveyor belt 403 for common transmission. When working, the motor 401 drives the rotating rollers 402 to rotate, which in turn drives the conveyor belt 403 to run, thus completing the conveying of bagged cement.

[0020] Reference Figure 1 - Figure 2 Side guard plates 5 are fixedly installed on both outer walls of the unblocking packaging machine 3 by bolts. The side guard plates 5 extend along the conveying direction and protrude from the upper surface of the conveyor belt 403. During the conveying process, the side guard plates 5 can limit the bagged cement to prevent the bagged cement from deviating and detaching from the conveyor belt 403 during the inclined conveying process, thereby improving the conveying stability.

[0021] The output end of the high-standard packaging machine 1 is fixedly installed with a feeding chute 7 by bolts. The feeding chute 7 is an integrated inclined guiding steel structure. The high end of the feeding chute 7 connects to the feeding end of the internal conveying unit 4 of the high-standard packaging machine 1, and the low end extends downwards and connects to the feeding end of the conveying unit 4 of the unblocking packaging machine 3. After the bagged high-standard cement is packaged by the high-standard packaging machine 1, it slides smoothly down the feeding chute 7 after being fed from the conveying unit 4, and finally falls into the upper end of the conveying unit 4 of the unblocking packaging machine 3. The guiding effect of the inclined chute can prevent the bagged cement from being swept off course and falling when it is fed, thus improving the feeding stability.

[0022] Reference Figure 2 - Figure 3 Near the discharge end of the top of the unclogging and packaging machine 3, a guide transfer structure 6 is fixedly installed by bolts. In this embodiment, the guide transfer structure 6 specifically includes an outer frame 601, an electric push rod 602, and a baffle 603. The outer frame 601 is a portal steel structure, and its bottom end is fixed to the top frame of the unclogging and packaging machine 3 by bolts. The two side legs of the outer frame 601 are respectively rotatably connected to one end of the electric push rod 602 and one end of the baffle 603 by pins. The electric push rod 602 is inclined, and its output end is rotatably connected to the middle of the baffle 603 by pins, thereby forming a rotatable angle-adjustable guide structure. The bottom end of the baffle 603 is set corresponding to the discharge end of the unclogging and packaging machine 3. During operation, the extension and retraction of the electric push rod 602 can be controlled to drive the baffle 603 to rotate around the hinge point, adjust the tilt angle of the baffle 603, and thus adjust the falling direction of the bagged cement output from the unblocking packaging machine 3, ensuring that the bagged cement can accurately fall into the upper end of the conveying unit 4 of the low-standard packaging machine 2, adapting to the adjustment needs of different conveying conditions.

[0023] The discharge end of the unblocking packaging machine 3 is close to the guide transfer structure 6 and is fixedly connected to a corner chute 8 by bolts. The corner chute 8 is an inclined material guiding structure corresponding to the conveying unit 4 of the low-standard packaging machine 2. After being guided by the baffle 603, the bagged cement output by the unblocking packaging machine 3 slides down along the corner chute 8 and finally falls steadily into the upper end of the conveying unit 4 of the low-standard packaging machine 2, further reducing the impact force of the falling cement and preventing the bagged cement from falling off at an angle.

[0024] The implementation principle of the conveyor belt docking assembly for cement production in this embodiment of the present invention is as follows: When high-grade cement is being shipped normally, after the high-grade packaging machine 1 completes the cement packaging, the bagged high-grade cement is conveyed to the output end by the conveying unit 4 inside the high-grade packaging machine 1, and falls smoothly into the upper end of the conveying unit 4 of the unblocking packaging machine 3 along the discharge chute 7; the conveying unit 4 of the unblocking packaging machine 3 drives the bagged cement to be conveyed upward at an incline. During the conveying process, the side guard plates 5 on both sides limit the bagged cement to prevent it from falling off; after reaching the discharge end of the unblocking packaging machine 3, the bagged cement is guided by the baffle 603 of the guide transfer structure 6 and the corner chute 8, and falls smoothly into the upper end of the conveying unit 4 of the low-grade packaging machine 2; the low-grade packaging machine 2 receives the bagged cement and sends the bagged cement into the main conveyor line of the low-grade packaging machine 2, and finally completes the automated pallet palletizing and loading and shipment through the automated shipping channel connected to the output end of the low-grade packaging machine 2.

[0025] The entire technical upgrade process only requires adding a dredging packaging machine 3 to the gap between the original high-grade packaging machine 1 and low-grade packaging machine 2 to complete the connection. It does not require changing the main layout of the original shipping system. At the same time, it utilizes the original dismantled idle equipment for assembly, which greatly reduces the cost of technical upgrade. After the upgrade, high-grade cement can be directly connected to the original automated shipping system, releasing the production capacity of high-grade packaging machine 1. The equipment utilization rate has increased from 42% before the upgrade to over 90%, meeting the market demand for high-grade palletized cement and solving the pain point of mismatch between production capacity supply and market demand for small and medium-sized cement enterprises. Example 2

[0026] The difference between this embodiment and embodiment one is that in this embodiment, when high-grade cement and low-grade cement need to be shipped simultaneously, the angle of the baffle 603 can be adjusted by the electric push rod 602 to completely block the discharge end of the corner chute 8 of the unblocking and packaging machine 3. The bagged cement output by the high-grade packaging machine 1 will no longer be transferred to the low-grade packaging machine 2. Instead, it will be directly transported along the main conveying path of the unblocking and packaging machine 3 to the reserved manual loading channel on the side to complete the shipment. The entire process does not interfere with the automated conveying process of the low-grade packaging machine 2 and does not affect the normal automated shipment of low-grade cement. It is suitable for the working conditions of simultaneous shipment of multiple types of cement and has greater overall flexibility. Example 3

[0027] Based on Embodiment 1, this embodiment further optimizes the design of the low-profile packaging machine 2 at the material discharge position of the corner chute 8: A reinforced rotating idler roller 20 is rotatably installed at the material discharge point of the corner chute 8 inside the low-standard packaging machine 2. This rotating idler roller 20 is independent of the transmission system of the original conveying unit of the low-standard packaging machine 2. It is made of reinforced impact-resistant rotating roller material processed from seamless steel pipe. The roller body surface is covered with a 3mm thick wear-resistant rubber layer. The two ends of the roller body are fixed to the frame of the low-standard packaging machine 2 by bearings with seats. The installation height is slightly lower than the lowest discharge port of the corner chute 8 and is flush with the upper surface of the original conveyor belt of the low-standard packaging machine 2.

[0028] When the bagged cement slides out of the corner chute 8 quickly, it first comes into contact with the rubber-coated rotating idler roller 20, which can greatly buffer the impact of the falling cement and prevent the packaging bag from being torn by sharp parts; at the same time, the independently driven rotating idler roller 20 can effectively support the impact generated when the cement falls, especially suitable for continuous shipment of high-grade cement with a large flow rate of more than 120 tons per hour, effectively improving the smoothness of the conveying.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
