Description

Technical Field

[0001] This utility model relates to the technical field of ton bag feeding stations, and in particular to a special ton bag feeding station for pneumatic conveying. Background Technology

[0002] A ton bag feeding station is a device used to process materials packaged in ton bags. It is mainly used for unpacking and unloading powdery and granular materials. As a main material feeding device, the ton bag feeding station is prone to dust generation during bag cutting and bag collection. Existing dust removal structures cannot effectively remove this dust, so the dust removal method of the ton bag feeding station needs to be optimized.

[0003] The original ton bag feeding station only has a quick-opening dust removal interface on the rear side of the outer ring of the dust removal system. Setting the dust removal interface only on the rear side may result in dust from other directions not being effectively collected. Especially during the material unloading process, dust may escape from other directions and cannot be covered by the dust removal system, leading to dust accumulation, affecting the working environment, making maintenance and operation difficult, and reducing the efficiency of the ton bag feeding station. Utility Model Content

[0004] The purpose of this utility model is to provide a special ton bag feeding station for pneumatic conveying to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this utility model is as follows: A pneumatic conveying ton bag feeding station includes a dust removal mechanism, a flexible connecting pipe, a feeding mechanism, a ton bag discharge port, a vibration mechanism, a feeding mechanism, and a ton bag tapping mechanism. The dust removal mechanism is located inside the feeding mechanism, and the ton bag discharge port is located inside the dust removal mechanism. The lower end of the ton bag discharge port is connected to the feeding mechanism through the flexible connecting pipe. The vibration mechanism is located on the outer wall of the feeding mechanism and connected to the flexible connecting pipe. The ton bag tapping mechanism is installed on the periphery of the feeding mechanism.

[0006] Preferably, the feeding mechanism includes a first support and a ton bag support, with the ton bag support provided at the upper end of the first support.

[0007] Preferably, the system also includes a feeding station frame, a gantry crane guide rail, an electric hoist, and a hook. The feeding station frame is located outside the feeding mechanism. The gantry crane guide rail is located at the upper end of the feeding station frame. The electric hoist is located on the gantry crane guide rail, and the hook is located at the lower end of the electric hoist.

[0008] As a further preferred embodiment, the dust removal mechanism includes a first dust removal hood, a second dust removal hood, and a lifting cylinder. The first dust removal hood is connected to the upper end of the first support, the second dust removal hood is located above the first dust removal hood, the lifting cylinder is disposed on the outer wall of the first dust removal hood and connected to the second dust removal hood, and the upper end of the flexible connecting pipe is disposed inside the first dust removal hood and connected to the inner wall of the first dust removal hood.

[0009] As a further preferred embodiment, the outer wall of the first dust collector is provided with a spare dust collector port, and the outer wall of the second dust collector is provided with a main dust collector port.

[0010] As a further preferred embodiment, the material feeding port cover is also included, with the material feeding port cover provided at the upper end of the second dust removal hood.

[0011] As a further preferred embodiment, the ton bag tapping mechanism includes a tapping cylinder and a tapping hammer disposed at the output end of the tapping cylinder, the tapping cylinder being connected to the outer wall of the first bracket.

[0012] As a further preferred embodiment, the feeding mechanism includes a feeding machine, a screen, an air inlet, and a pneumatic valve. The feeding machine is installed inside the first support. The discharge port of the feeding machine is connected to a vacuum feeder for negative pressure conveying or a powder delivery tank for positive pressure conveying via a pipeline. The screen is installed inside the feeding machine. One side of the feeding machine is connected to the air inlet via the pneumatic valve.

[0013] As a further preferred embodiment, it also includes a dust collection mechanism, which is symmetrically arranged on both sides of the dust removal mechanism; The dust collection mechanism includes a dust collection hood, a fixed rod, a mounting plate, and a quick-opening connector. The lower end of the mounting plate is connected to the fixed rod, and the dust collection hood is provided at the lower end of the fixed rod. The quick-opening connector is provided on one side of the dust collection hood, and several dust collection holes are provided on the other side of the dust collection hood.

[0014] The above technical solution has the following advantages or beneficial effects: In this invention, by adding dust collection mechanisms on both sides of the dust removal mechanism, the dust removal system can collect dust simultaneously from multiple directions. This multi-directional dust collection design effectively solves the problem in the prior art where dust collection cannot be effectively achieved using only the rear dust collection interface.

[0015] In this invention, the spare dust removal interface on the outer wall of the first dust removal hood and the main dust removal interface on the outer wall of the second dust removal hood work together to enhance the reliability and flexibility of the dust removal system. Under normal circumstances, the main dust removal interface can meet most of the dust removal needs and ensure the dust collection effect during the production process. When the main dust removal interface malfunctions or a stronger dust removal capacity is required, the spare dust removal interface can be put into use immediately to ensure uninterrupted dust removal.

[0016] In this utility model, the feeding port cover plate covers the feeding port when not in operation and after feeding is completed, providing effective protection for the equipment. It can also prevent external debris from entering the ton bag feeding station, avoiding damage to the equipment, and ensuring the purity of the material.

[0017] In this invention, the connecting pipe connects the ton bag's discharge port to the feeding mechanism, playing a crucial buffering role during the feeding process. Since the vibration mechanism generates significant vibration during operation, the flexibility of the flexible connecting pipe absorbs this vibration energy, preventing excessive vibration from damaging the ton bag's discharge port and the feeding mechanism. This extends the equipment's service life and reduces maintenance costs. Attached Figure Description

Figure 1 ; Figure 2 This is a side view of the pneumatic conveying ton bag feeding station of this utility model. Figure 2 ; Figure 3 This is a three-dimensional structural diagram of the pneumatic conveying ton bag feeding station of this utility model; Figure 4 This is a structural schematic diagram of the dust collection mechanism in this utility model. Please refer to [link / reference]. Figures 1 to 4The diagram illustrates a preferred embodiment of a pneumatic conveying ton bag feeding station, comprising a dust removal mechanism 1, a flexible connecting pipe 2, a feeding mechanism 3, a ton bag discharge port 4, a vibration mechanism 5, a discharge mechanism 6, and a ton bag tapping mechanism 7. The dust removal mechanism 1 is located inside the feeding mechanism 3, and the ton bag discharge port 4 is located inside the dust removal mechanism 1. The lower end of the ton bag discharge port 4 is connected to the discharge mechanism 6 via the flexible connecting pipe 2. The vibration mechanism 5 is located on the outer wall of the discharge mechanism 6 and connected to the flexible connecting pipe 2. The ton bag tapping mechanism 7 is installed around the periphery of the feeding mechanism 3. In this embodiment, the feeding mechanism 3 supports the ton bag. The dust removal mechanism 1 is arranged around the ton bag discharge port 4 to collect dust generated during unloading. The ton bag discharge port 4 serves as the material outlet. The material enters the discharge mechanism 6 through the flexible connecting pipe 2, which has a certain degree of flexibility and can change according to the movements of the discharge mechanism 6 and the vibration mechanism 5. The vibration mechanism 5 promotes smooth material discharge through vibration, preventing blockages. Vibration mechanism 5 can be a vibration motor. Connecting vibration mechanism 5 to the outer wall of flexible connecting pipe 2 prevents excessive vibration during feeding and acts as a buffer. Ton bag tapping mechanism 7 is installed around the feeding mechanism 3. During unloading, it taps the ton bag to loosen the material inside, facilitating unloading. When the ton bag is placed on the feeding mechanism 3, the outer bag is opened and the inner bag is cut open. Under gravity, the material enters the discharging mechanism 6 through flexible connecting pipe 2. At this time, vibration mechanism 5 is activated, using vibration to help the material flow smoothly. Simultaneously, ton bag tapping mechanism 7 taps the ton bag to prevent material from clumping or accumulating and affecting discharging.

[0024] Furthermore, as a preferred embodiment, the feeding mechanism 3 includes a first support 301 and a ton bag support 302, with the ton bag support 302 located at the upper end of the first support 301. The ton bag support 302 is fixedly mounted on the upper end of the first support 301 to support the ton bag. In actual operation, the ton bag is hoisted onto the ton bag support 302, and the first support 301 bears the weight of the ton bag, ensuring that the ton bag does not shift during unloading, thus enabling the unloading process to proceed smoothly. In this embodiment, the unloading mechanism 6 is located inside the first support 301. The dust removal mechanism 1 is located between the first support 301 and the ton bag support 302.

[0025] Furthermore, as a preferred embodiment, the system also includes a feeding station frame 8, a gantry crane rail 9, an electric hoist 10, and a hook 11. The feeding station frame 8 is located outside the feeding mechanism 3. The upper end of the feeding station frame 8 is equipped with the gantry crane rail 9, and the electric hoist 10 is mounted on the gantry crane rail 9. The lower end of the electric hoist 10 is equipped with a hook 11. The electric hoist 10 can move on the gantry crane rail 9. Since the cooperation method between the electric hoist 10 and the gantry crane rail 9 is existing technology, it will not be limited here. The electric hoist 10 is driven by a motor to realize the lifting function of the hook 11. When it is necessary to lift the ton bag, the operator controls the electric hoist 10 to move to a suitable position on the gantry crane rail 9, then lowers the hook 11, lifts the ton bag and transports it above the ton bag support 302, and then lowers the ton bag to complete the lifting process. This lifting structure design greatly improves the convenience and efficiency of ton bag handling and reduces the labor intensity and time cost of manual handling of ton bags.

[0026] Furthermore, as a preferred embodiment, the dust removal mechanism 1 includes a first dust removal hood 101, a second dust removal hood 102, and a lifting cylinder 103. The first dust removal hood 101 is connected to the upper end of the first support 301, the second dust removal hood 102 is located above the first dust removal hood 101, the lifting cylinder 103 is disposed on the outer wall of the first dust removal hood 101 and connected to the second dust removal hood 102, and the upper end of the flexible connecting pipe 2 is disposed inside the first dust removal hood 101 and connected to the inner wall of the first dust removal hood 101. In this embodiment, during use, the lifting cylinder 103 can drive the second dust removal hood 102 to rise or fall. After the second dust removal hood 102 falls, it can press down on the outer bag of the ton bag, thereby fixing the position of the ton bag. When the material enters the feeding mechanism 6 through the flexible connecting pipe 2, the first dust removal hood 101 and the second dust removal hood 102 work together to collect the generated dust. In the initial stage of unloading, the lifting cylinder 103 lowers the second dust collector hood 102 closer to the ton bag discharge port 4. This not only tightens the outer bag of the ton bag but also enhances the dust collection effect. In this embodiment, the upper outer wall of the flexible connecting pipe 2 can be connected and fixed to the inner wall of the first dust collector hood 101 via a connecting rod to support the flexible connecting pipe 2. The lifting cylinder 103 is bolted to the outer wall of the first dust collector hood 101, and the output end of the lifting cylinder 103 is bolted to the outer wall of the second dust collector hood 102. In this embodiment, the first dust collector hood 101 is bolted to the first bracket 301, and the first dust collector hood 101 is located at the upper end of the first bracket 301.

[0027] Furthermore, as a preferred embodiment, a backup dust collection port 104 is provided on the outer wall of the first dust collection hood 101, and a main dust collection port 105 is provided on the outer wall of the second dust collection hood 102. Under normal circumstances, the main dust collection port 105 is connected to external dust collection equipment and is responsible for the main dust collection work. When the main dust collection port 105 malfunctions, or when enhanced dust collection is required, or when special dust collection operations are performed, the backup dust collection port 104 can be quickly connected to external dust collection equipment and put into use. The dual dust collection port design greatly improves the reliability of the dust collection system. When the main dust collection port 105 malfunctions, the backup dust collection port 104 can take over in time, ensuring the normal operation of the ton bag feeding station and preventing a large amount of dust from escaping due to dust collection system failure, which could affect the working environment and the health of operators. At the same time, in some working conditions with high dust collection requirements, the main and backup dust collection ports 104 can be used simultaneously to enhance the dust collection effect and ensure that the dust concentration in the working area is always kept at a low level.

[0028] Furthermore, as a preferred embodiment, a feeding port cover 303 is also included, with the feeding port cover 303 provided at the upper end of the second dust collector hood 102. The feeding port cover 303 is closed when the ton bag feeding station is not in operation and after feeding is completed. When feeding is required, the feeding port cover 303 is opened. The feeding port cover 303 effectively protects the internal structure of the equipment, preventing debris from entering and damaging the equipment, while also preventing debris from mixing with the material, ensuring the purity of the material, and thus improving the quality of subsequent products. In addition, it also prevents residual material from being exposed to the air, causing secondary dust re-entrainment, further improving the working environment.

[0029] Furthermore, as a preferred embodiment, the ton bag tapping mechanism 7 includes a tapping cylinder 701 and a tapping hammer 702 located at the output end of the tapping cylinder 701. The tapping cylinder 701 is connected to the outer wall of the first support 301. When the ton bag is placed on the ton bag support 302 for unloading, the tapping cylinder 701 drives the tapping hammer 702 to reciprocate, tapping the ton bag. The tapping frequency and force can be adjusted according to the characteristics of the material inside the ton bag. For example, for materials that are prone to clumping, the tapping force and frequency can be appropriately increased to loosen the clumped material and facilitate its smooth flow from the ton bag discharge port 4. The ton bag tapping mechanism 7 effectively solves the problem of poor material discharge caused by material clumping or accumulation, improving unloading efficiency. Moreover, by loosening the material through tapping, it reduces the need for manual intervention due to material blockage, lowers the workload of operators, and ensures the continuity of the feeding process, improving the overall efficiency of the ton bag feeding station. The striking cylinder 701 is mounted on the outer wall of the first bracket 301 by bolts.

[0030] Furthermore, as a preferred embodiment, the feeding mechanism 6 includes a feeding machine 601, a screen, an air inlet 602, and a pneumatic valve 603. The feeding machine 601 is installed inside the first bracket 301. The discharge port of the feeding machine 601 is connected externally to a vacuum feeder for negative pressure conveying or a powder conveying tank for positive pressure conveying via a pipeline. A screen is installed inside the feeding machine 601. One side of the feeding machine 601 is connected to the air inlet 602 via the pneumatic valve 603. See also Figure 1 As shown, a crossbar 304 for connecting the feeding machine 601 is provided on the inner side of the first support 301. The feeding machine 601 is connected to the crossbar 304 by bolts to fix the feeding machine 601. The screen inside the feeding machine 601 screens the material, intercepting larger particles or impurities to ensure the quality of the output. The air inlet 602 is connected to one side of the feeding machine 601 through a pneumatic valve 603. By controlling the opening of the pneumatic valve 603, the amount of air entering the feeding machine 601 is adjusted, so that the material can be smoothly conveyed to the vacuum feeder.

[0031] The design of the feeding mechanism 6 in this embodiment ensures that materials are effectively screened before conveying, improving the quality of the conveyed materials and preventing impurities from damaging subsequent production equipment. At the same time, different conveying methods can be selected according to actual production needs, increasing the applicability of the equipment. Furthermore, by controlling the air supply, problems such as blockage and adsorption during material conveying are effectively prevented, ensuring smooth material conveying and improving the stability and efficiency of the entire production process.

[0032] Furthermore, as a preferred embodiment, it also includes a dust collection mechanism 12, which is symmetrically arranged on both sides of the dust removal mechanism 1; The dust collection mechanism 12 includes a dust collection hood 1201, a fixing rod 1202, a mounting plate 1203, and a quick-opening interface 1204. The lower end of the mounting plate 1203 is connected to the fixing rod 1202, and the dust collection hood 1201 is provided at the lower end of the fixing rod 1202. The quick-opening interface 1204 is provided on one side of the dust collection hood 1201, and several dust collection holes 1205 are provided on the other side of the dust collection hood 1201. In this embodiment, the mounting plate 1203 is connected to the feeding station frame 8 by bolts, and the mounting plate 1203 is welded to the fixing rod 1202. The lower end of the fixing rod 1202 is welded to the dust collection hood 1201. The quick-opening interface 1204 communicates with the interior of the dust collection hood 1201 and is used to connect to an external negative pressure device to provide negative pressure inside the dust collection hood 1201, facilitating the suction of surrounding air containing dust. During the unloading process of the ton bag, dust disperses in all directions. The dust collection holes 1205 of the dust collection mechanisms 12 on both sides can capture dust from the sides, working together with the main dust collection interface 105 and the backup dust collection interface 104 to form multi-directional dust collection. This dust collection mechanism 12 greatly enhances the dust collection capacity of the dust removal system, collecting dust from multiple directions simultaneously. This not only effectively reduces the dust concentration in the working environment and protects the health of operators, but also reduces dust corrosion of equipment and extends the service life of the equipment.

[0033] In this embodiment, the main dust removal interface 105 and the backup dust removal interface 104 are respectively connected to external dust removal equipment through dust removal pipes.

[0034] In this embodiment, the dust removal equipment, vibration motor, lifting cylinder 103, electric hoist 10, tapping cylinder 701, pneumatic valve 603, vacuum feeder, negative pressure equipment, etc. are all connected to an external controller (PLC controller), which facilitates the automatic control of each device.

[0035] In use, first open the feeding port cover 303. The powder in the ton bag is lifted by the hook 11 on the electric hoist to the feeding platform at the feeding port cover 303, and falls onto the ton bag support 302. Then, the lifting cylinder 103 pushes the second dust collector 102 upward. The operator manually passes the feeding port of the ton bag through the second dust collector 102 and unties and pulls out the inner bag. After cutting the inner bag, the outer bag is quickly placed around the upper part of the first dust collector 101. Then, the lifting cylinder 103 drives the second dust collector 102 to descend and press the outer bag. The dust collection pipe of the main dust collection interface 105 can be activated in advance to prevent dust from overflowing. When the powder in the ton bag falls, the tapping cylinder 701 drives the tapping hammer 702 to reciprocate, tapping the ton bag to accelerate the outflow of powder and prevent material accumulation in dead corners inside the bag. The vibrating motor starts, accelerating the passage of powder and filtering out large-diameter foreign objects through a screen. The powder falls to the outlet of the feeder 601. The outlet is connected to a vacuum feeder with negative pressure or a powder delivery tank with positive pressure through a pipeline. The inside of the outlet is under negative pressure. The powder falling to the outlet is sucked into the pneumatic conveyor above the storage tank by the negative pressure pneumatic force, thus completing the powder feeding. The air replenishment port 602 of the feeder 601 is used to replenish air inside the feeder 601 to accelerate the transfer of material from the ton bag through the negative pressure pneumatic conveying. The pneumatic valve 603 is used to control the opening and closing of the air replenishment port 602. The feeding port cover 303 covers the feeding port when not in operation and after feeding to prevent foreign objects from entering. The flexible connecting pipe 2 connects the ton bag feeding port 4 to the vibrating motor below to prevent excessive vibration during feeding and to act as a buffer.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
