Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for chemical product production, and more specifically, to a powder bag feeding system. Background Technology

[0002] Steel structure coating is a specialized material applied to the surface of steel structures. Applying this coating effectively protects the steel structure and extends its service life. The initial preparation of the steel structure coating takes place in a reactor. This process requires the input of a large amount of powdered raw materials. The raw materials are purchased by the company and are packaged in bags. Workers must manually insert the powder bags into the reactor's feeding port. Because the raw materials are powdered, dust inevitably flies out during feeding. Since this is done manually, the dust poses a significant health risk to the workers. Furthermore, the weight of each powder bag is relatively heavy, making the feeding operation labor-intensive, time-consuming, and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a powder bag feeding system. This system uses a powder bag elevator to lift the powder bags, a powder bag conveyor belt to transport the powder bags, and a feeder to break and deliver the powder bags. This system has the advantage of high automation, which can greatly reduce the labor intensity of workers. Workers can work in a location far away from the feeding point, and the impact of dust on workers is greatly reduced, which can effectively protect the health of workers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A powder bag feeding system is applied to a coating preparation reactor, comprising a feeder, a powder bag conveyor belt, and a powder bag elevator. The feeder, conveyor belt, and elevator are arranged in a straight line. The feeder is installed at the end of the powder bag conveyor belt in the direction of travel, and the elevator is installed at the beginning of the conveyor belt in the direction of travel.

[0006] Furthermore, the feeder is provided with a bag dropping channel, a blocking screen is installed at the bottom of the bag dropping channel, a bag breaking cone is vertically connected to the center of the blocking screen, and a bag breaking blade is installed on the side wall of the bag dropping channel.

[0007] Furthermore, the powder bag lifting device includes a lifting frame and a bag placement platform. Two lifting frames are installed symmetrically, and each lifting frame is equipped with a first lifting cylinder. The first lifting cylinder is installed vertically downward, and the piston rod end of the first lifting cylinder is connected to the bag placement platform. The two first lifting cylinders extend and retract synchronously, and the two first lifting cylinders can drive the bag placement platform to perform vertical lifting and lowering movements. The raw material powder bags can be placed on the bag placement platform.

[0008] Furthermore, several movable rollers are rotatably installed on the platform surface of the bagging platform, and these movable rollers are laid in a straight line towards the powder bagging conveyor belt.

[0009] Furthermore, a rising limit switch is installed inside the lifting frame. The rising limit switch blocks the rising trajectory of the bag-laying platform. When the bag-laying platform contacts the rising limit switch, the bag-laying platform is flush with the powder bag conveyor belt.

[0010] Furthermore, a waste bag recycling device is installed at the feeder location. The waste bag recycling device includes a trolley frame and a mobile trolley. The trolley frame is straddling the feeder, and two parallel track beams are provided on the trolley frame. The mobile trolley is movably mounted on the two track beams and can move along the length of the track beams. A second lifting cylinder is installed on the mobile trolley. The second lifting cylinder is installed vertically downward, and a pneumatic gripper is connected to the piston rod end of the second lifting cylinder. The pneumatic gripper can extend into the feeder and move.

[0011] Furthermore, the waste bag recycling device also includes a waste bag recycling bin, which is placed on the side of the feeder, and the vehicle track beam extends to the location of the waste bag recycling bin.

[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] like Figures 1-3 The illustrated powder bag feeding system, applied to a coating preparation reactor, includes a feeder 1, a powder bag conveyor belt 2, and a powder bag elevator 3. The feeder 1, conveyor belt 2, and elevator 3 are arranged in a straight line. The feeder 1 is installed at the end of the conveyor belt 2 in the direction of travel and is used for final powder bag feeding. The elevator 3 is installed at the beginning of the conveyor belt 2 in the direction of travel, allowing workers to easily lift and place powder bags onto the conveyor belt 2. The conveyor belt 2 serves as an intermediate conveyor. The feeder 1 is vertically connected, with its lower end inserted into the feeding port of the coating preparation reactor to ensure that all powder is fed into the reactor. The top of the feeder 1 is lower than the surface of the powder bag conveyor belt 2. The powder bags conveyed from the powder bag conveyor belt 2 automatically fall into the feeder 1 after reaching the end. When this utility model is applied, the worker only needs to work at the powder bag elevator 3. Since the powder bag elevator 3 is far away from the feeder 1, the dust generated during feeding is unlikely to affect the worker at a distance, which can effectively protect the health of the worker.

[0020] like Figure 3As shown, the feeder 1 is equipped with a bag-dropping channel 11, which is inclined. After the powder bag enters, it can slide down the bag-dropping channel 11. A blocking screen 12 is installed at the bottom of the bag-dropping channel 11. The blocking screen 12 can prevent the powder bag from falling further. At the same time, the blocking screen 12 can screen the powder, break up large powder lumps, and create a fine powder falling effect. A bag-breaking cone 13 is vertically connected to the center of the blocking screen 12. The tip of the bag-breaking cone 13 faces upwards, so that when the powder bag falls, it is just right. The powder can impact the breaking cone 13, causing the powder to break. After breaking, the powder inside the bag can naturally leak out, creating a feeding effect. A breaking blade 14 is installed on the side wall of the bag dropping channel 11. The breaking blade 14 assists in breaking the bag. As the powder bag slides down the bag dropping channel 11, the breaking blade 14 can cut through the outer wall of the bag, also creating a breaking effect. This utility model combines the breaking cone 13 and the breaking blade 14 to ensure that the breaking and feeding operations are completed smoothly.

[0021] like Figure 2 As shown, the powder bag lifter 3 includes a lifting frame 31 and a bag placement platform 32. The two lifting frames 31 are installed symmetrically, and the bag placement platform 32 is installed between the two lifting frames 31. Each lifting frame 31 is equipped with a first lifting cylinder 33, which is installed vertically downward. The piston rod end of the first lifting cylinder 33 is connected to the bag placement platform 32. The two first lifting cylinders 33 extend and retract synchronously, which can drive the bag placement platform 32 to move. The two first lifting cylinders 33 can drive the bag placement platform 32 to make vertical lifting and lowering movements. After the bag placement platform 32 is lowered, it is convenient for workers to place raw material powder bags on the bag placement platform 32. After the bag placement platform 32 is raised, it can dock with the powder bag conveyor belt 2 to facilitate powder bag conveying operations.

[0022] like Figure 1 and Figure 2 As shown, several movable rollers 321 are rotatably installed on the platform 32. The movable rollers 321 are laid in a straight line towards the powder bag conveyor belt 2. The powder bags are placed on the movable rollers 321. The movable rollers 321 can improve the mobility of the powder bags, so that workers can easily push the powder bags and push them onto the powder bag conveyor belt 2.

[0023] like Figure 2 As shown, a rising limit 34 is installed inside the lifting frame 31. The rising limit 34 blocks the rising trajectory of the bag-laying platform 32. When the bag-laying platform 32 contacts the rising limit 34, the bag-laying platform 32 is flush with the powder bag conveyor belt 2. At this time, the powder bag is raised to the correct height. The worker pushes the powder bag onto the powder bag conveyor belt 2. The powder bag lifting device 3 of this utility model is simple to operate and the powder bag placement operation is very labor-saving, which can greatly reduce the workload of the workers.

[0024] After the powder bags are fed in, the discarded packaging bags are still inside the feeder 1. This utility model is designed with an automated bag-retrieving structure to complete the waste bag recycling operation, such as... Figure 1 and Figure 3 As shown, a waste bag recycling device 4 is installed at the feeder 1. The waste bag recycling device 4 includes a trolley frame 41 and a moving trolley 42. The trolley frame 41 is straddling the feeder 1 to avoid affecting the normal feeding of powder bags. The trolley frame 41 is provided with two parallel traveling rail beams 411. The moving trolley 42 is movably mounted on the two traveling rail beams 411 and can move along the length of the traveling rail beams 411. A second lifting cylinder 43 is installed on the moving trolley 42. The second lifting cylinder 43 is installed vertically downwards. The piston rod end of cylinder 3 is connected to a pneumatic gripper 44. The moving trolley 42 can move to a position above the feeder 1. After the piston rod end of the second lifting cylinder 43 extends, the pneumatic gripper 44 can extend into the feeder 1. Through the action of the pneumatic gripper 44, the waste packaging bag inside the feeder 1 can be clamped. Then, the piston rod of the second lifting cylinder 43 retracts, and the pneumatic gripper 44 removes the waste packaging bag from the feeder 1. During the removal process, the residual powder inside the packaging bag will naturally fall off, which helps to fully feed the material. The waste bag recycling device 4 also includes a waste bag recycling bin 45, such as... Figure 3 As shown, the waste bag recycling bin 45 is placed on the side of the feeder 1, and the trolley track beam 411 extends to the waste bag recycling bin 45. That is to say, the mobile trolley 42 can move to the waste bag recycling bin 45. After the pneumatic gripper 44 takes the waste packaging bag out of the feeder 1, the mobile trolley 42 moves towards the waste bag recycling bin 45 and then puts the waste packaging bag into the waste bag recycling bin 45.

[0025] This invention has the advantage of a high degree of automation. A series of operations such as feeding and bag removal are completed automatically, which greatly reduces the workload of workers. When operating this invention, powder bags need to be fed at intervals, and time should be reserved for feeding and bag removal operations to avoid equipment accidents.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
