Description

Technical fields:

[0001] This utility model belongs to the technical field of feeding equipment, specifically referring to a dust-free unpacking station. Background technology:

[0002] In many industrial sectors such as chemical, food, pharmaceutical, and building materials, powdered or granular materials (such as resins, pigments, additives, pharmaceutical raw materials, and cement auxiliaries) are typically packaged, stored, and transported in woven bags, plastic bags, or composite bags. During subsequent production processes, these bagged materials need to be unpacked and the materials poured out or transferred to downstream equipment (such as silos, mixers, and reactors) for further processing.

[0003] Currently, this type of bag-opening operation still largely relies on manual labor. Workers manually cut or slice open the packaging bags with knives and then empty the contents. However, this traditional manual bag-opening method has a series of significant technical problems and drawbacks:

[0004] 1. Low efficiency and high labor intensity: In scenarios of large-scale, continuous production, the slow speed of manual bag opening becomes a bottleneck in the production process. Frequent cutting and pouring actions result in high labor intensity and easy fatigue for manual workers.

[0005] 2. Severe dust pollution: During the manual cutting of packaging bags and dumping of materials, a large amount of fine dust will inevitably be raised. This dust not only pollutes the working environment and endangers the health of employees, but also, some material dust has flammable and explosive properties, and dust increases the risk of explosion. Summary of the Invention:

[0006] The purpose of this invention is to provide a dust-free unpacking station that can replace the inefficient and dangerous manual bag-unpacking operation. It adopts automated cutting and dumping, and can efficiently filter the generated dust, effectively improving work efficiency and avoiding problems caused by dust.

[0007] This utility model is implemented as follows:

[0008] A dust-free unpacking station includes a housing, within which an unpacking chamber and a filter assembly connected to the bottom of the unpacking chamber are disposed. The filter assembly is used to screen material particles by size. A feed inlet is provided on one side of the housing located on the unpacking chamber, and a dust removal assembly is disposed on the housing located on the other side of the unpacking chamber. Three or more unpacking knife groups are circumferentially distributed on the housing located between the unpacking chamber and the filter chamber. Each unpacking knife group includes a power source disposed on the housing. The moving end of the power source is arranged radially, and an unpacking knife body with the blade facing upward is fixed on the moving end of the power source. The unpacking knife body is driven by the power source to move radially inward and outward.

[0009] In the aforementioned dust-free unpacking station, the filtration assembly includes a vibrating screening cylinder mounted on the casing via shock-absorbing springs. The upper port of the vibrating screening cylinder is sealed and connected to the bottom of the unpacking chamber via a flexible component. A filter screen is installed inside the vibrating screening cylinder, and the lower port of the vibrating screening cylinder is used to discharge materials outward. A vibrating motor capable of driving the vibrating screening cylinder to vibrate is installed on the outer wall of the vibrating screening cylinder.

[0010] In the aforementioned cleanroom unpacking station, the lower port of the vibrating screening cylinder is connected to one end of a four-way pipe. The other three ports of the four-way pipe are a negative pressure series inlet and a negative pressure series outlet for connecting with an external negative pressure feeding mechanism or other external equipment, and an air inlet for connecting with external gas media or the external atmosphere.

[0011] In the aforementioned dust-free unpacking station, the dust removal component includes a dust removal baffle installed inside the unpacking chamber, forming a sealed dust removal cavity between the dust removal baffle and the unpacking chamber. The air inlet of a dust removal fan fixed on the casing is connected to the dust removal cavity, and the air outlet of the dust removal fan is connected to the outside. The dust removal baffle is provided with several dust removal assembly through holes, and a dust removal filter element is installed in each dust removal assembly through hole.

[0012] In the aforementioned dust-free unpacking station, a high-pressure gas storage tank is fixed on the outer wall of the casing. The high-pressure gas storage tank is connected to the dust removal chamber through pulse solenoid valves and pipelines, and the number and position of the pulse solenoid valves correspond one-to-one with the dust removal filter elements.

[0013] In the aforementioned dust-free unpacking station, the unpacking chamber includes an unpacking section and a dust removal and adsorption section that are connected from left to right. The feed inlet is located on the side wall of the unpacking section away from the dust removal and adsorption section. The bag-opening knife assembly and the filter assembly are both installed on the unpacking section. The dust removal assembly is installed on the dust removal and adsorption section, and the bottom surface of the dust removal and adsorption section is an inclined guide surface that is inclined downward toward the unpacking section.

[0014] In the aforementioned dust-free unpacking station, a vertically arranged barrier partition is provided between the dust removal and adsorption section and the unpacking section. The barrier partition separates the dust removal and adsorption section from the left and right, and there is a matching gap between the bottom edge of the barrier partition and the inclined guide surface for the material to slide from the dust removal and adsorption section into the unpacking section. The barrier partition is evenly distributed with barrier through holes.

[0015] In the aforementioned cleanroom unpacking station, a cross bracket is fixedly installed in the unpacking compartment located directly above the filter assembly, and four unpacking knife sets are provided and distributed circumferentially around the intersection of the cross brackets on each arm of the cross brackets.

[0016] In the aforementioned cleanroom unpacking station, the power source is a rodless cylinder. The two ends of the rodless cylinder are respectively mounted on the same arm of the cross support. The unpacking knife body is fixed on the sliding assembly of the rodless cylinder, and the bottom end of the sliding assembly is in rolling cooperation with the corresponding arm of the cross support through rollers.

[0017] In the aforementioned cleanroom unpacking station, each arm of the cross support has an inverted triangular cross section, and the outer wheel surface of the roller has a triangular annular groove that matches the corresponding arm structure of the cross support.

[0018] The outstanding advantages of this utility model compared to the prior art are:

[0019] This invention can replace the inefficient and dangerous manual bag-opening operation. It uses multiple sets of radially movable bag-opening blades to achieve orderly and regular cutting of the bag. While the filter component further screens the falling material, the dust removal component efficiently adsorbs the falling material and the powder raised by the screening, effectively improving work efficiency and avoiding problems caused by flying dust.

[0024] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3:

[0025] A dust-free unpacking station includes a housing 1, inside which is an unpacking chamber 2 and a filter assembly connected to the bottom of the unpacking chamber 2. The filter assembly is used to screen the particle size of the material. A feed inlet 3 is provided on one side of the housing 1 located in the unpacking chamber 2, and a dust removal assembly is provided on the other side of the housing 1 located in the unpacking chamber 2. Three or more bag-opening knife groups are circumferentially distributed on the housing 1 between the unpacking chamber 2 and the filter chamber. Each bag-opening knife group includes a power source provided on the housing 1. The moving end of the power source is arranged radially, and a bag-opening knife body 4 with the blade facing upward is fixed on the moving end of the power source. The bag-opening knife body 4 is driven by the power source to move radially inward and outward.

[0026] It should be noted that bagged materials can be manually placed into the unpacking chamber 2 through the feed inlet 3. Multiple sets of radially movable unpacking knives cut the bottom of the bag, allowing the material to fall into the filter assembly. After particle screening by the filter assembly, the material can be used in subsequent downstream equipment. At the same time, the bag after being cut can be manually removed.

[0027] In this embodiment, considering the safety of the operation and in order to further improve the degree of automation and work efficiency, a robotic arm is used to pick up the bagged material and transfer it into the unpacking chamber 2. After the bag is cut open and emptied, the robotic arm transfers it out of the unpacking chamber 2 and picks up the next bagged material for the bag-breaking operation.

[0028] This invention can replace the inefficient and dangerous manual bag-opening operation. It uses multiple sets of radially movable bag-opening blades to achieve orderly and regular cutting of the bag. While the filter component further screens the falling material, the dust removal component efficiently adsorbs the falling material and the powder raised by the screening, effectively improving work efficiency and avoiding problems caused by flying dust.

[0029] Furthermore, the filtration assembly can directly use a simple filter screen to screen the particle size of the material. Considering that dusty materials are prone to accumulation, in this embodiment, the filtration assembly includes a vibrating screening cylinder 6 mounted on the housing 1 by shock-absorbing springs 5. The upper port of the vibrating screening cylinder 6 is sealed to the bottom of the unpacking chamber 2 through a flexible component 7. A filter screen is installed inside the vibrating screening cylinder 6, and the lower port of the vibrating screening cylinder 6 is used to discharge materials outward. A vibrating motor 8 is installed on the outer wall of the vibrating screening cylinder 6 to drive the vibrating screening cylinder 6 to vibrate. That is, the vibration generated by the vibrating motor 8 allows the material to vibrate on the filter screen and fall smoothly downward. The flexible component 7 can be a ring made of silicone or a folded accordion-shaped protective cover.

[0030] Meanwhile, considering the material conveying of downstream equipment, the lower port of the vibrating screening cylinder 6 is connected to one end of the four-way pipe 9. The other three ports of the four-way pipe 9 are a negative pressure series inlet 10 and a negative pressure series outlet 11 for connecting with an external negative pressure feeding mechanism or other external equipment, and an air inlet 12 for connecting with external gas media or the outside atmosphere. The negative pressure power source and the pipeline downstream equipment can be used to connect the negative pressure series inlet 10 and negative pressure series outlet 11 of this product. This product can also have two or more units installed side-by-side, with the negative pressure series inlet 10 of one dust-free bag-opening device connected to the negative pressure series outlet 11 of another dust-free bag-opening device via a pipeline, thus realizing a complete route for material bag opening, feeding, and negative pressure conveying. Furthermore, if the material is a hazardous dust material that is not easily in direct contact with the outside atmosphere during conveying, the air inlet 12 can be connected to an inert gas source, such as nitrogen, to replace air for negative pressure material conveying.

[0031] The specific structure of the dust removal component is as follows: the dust removal component includes a dust removal partition 13 installed in the unpacking chamber 2, and a sealed dust removal chamber 14 is formed between the dust removal partition 13 and the unpacking chamber 2. The air inlet of the dust removal fan 15 fixed on the housing 1 is connected to the dust removal chamber 14, and the air outlet of the dust removal fan 15 is connected to the outside. Several dust removal assembly through holes are opened on the dust removal partition 13, and a dust removal filter element 16 is installed in each dust removal assembly through hole.

[0032] Furthermore, in order to allow the dust adhering to the dust collector filter element 16 to fall and be recycled, a high-pressure air tank 17 is fixed on the outer wall of the housing 1. The high-pressure air tank 17 is connected to the dust collection chamber 14 through a pulse solenoid valve 18 and a pipeline, and the number and position of the pulse solenoid valve 18 correspond one-to-one with the dust collector filter element 16.

[0033] In this embodiment, in order to enable the dust removal component to effectively adsorb flying dust and prevent the dust from drifting out from the feed inlet 3, the unpacking chamber 2 includes an unpacking section 19 and a dust removal adsorption section 20 that are connected from left to right. The feed inlet 3 is opened on the side wall of the unpacking section 19 away from the dust removal adsorption section 20. The bag-opening knife assembly and the filter assembly are both arranged on the unpacking section 19. The dust removal component is arranged on the dust removal adsorption section 20, and the bottom surface of the dust removal adsorption section 20 is an inclined guide surface that is inclined downward towards the unpacking section 19.

[0034] Meanwhile, in order to prevent the cut bags and related fabrics from being adsorbed by the dust removal components, a barrier plate 21 is provided vertically between the dust removal adsorption part 20 and the unpacking part 19. The barrier plate 21 separates the dust removal adsorption part 20 and the unpacking part 19 from left and right. There is a matching gap between the bottom edge of the barrier plate 21 and the inclined guide surface for the material to slide from the dust removal adsorption part 20 into the unpacking part 19. The barrier plate 21 is evenly distributed with barrier through holes 22.

[0035] In order to enable the bag-opening knife assembly to move radially back and forth stably in the unpacking chamber 2, in this embodiment, a cross bracket 23 is fixedly mounted in the unpacking chamber 2 located directly above the filter assembly. The bag-opening knife assembly is provided with four pieces and is circumferentially distributed around the intersection of the cross bracket 23 on each arm of the cross bracket 23.

[0036] Furthermore, the power source can be a telescopic cylinder or a servo motor and a screw and nut combination structure. In this embodiment, the power source is a rodless cylinder 24. The two ends of the rodless cylinder 24 are respectively mounted on the same arm of the cross bracket 23. The bag-opening knife body 4 is fixed on the sliding component 25 of the rodless cylinder 24. Considering that the scattering of powder material will affect the sliding of the sliding component 25 on the corresponding arm of the cross bracket 23, the bottom end of the sliding component 25 is rolled in cooperation with the corresponding arm of the cross bracket 23 through the roller 26.

[0037] Furthermore, each arm of the cross bracket 23 has an inverted triangular cross-section, and the outer wheel surface of the roller 26 has a triangular annular groove that matches the corresponding arm structure of the cross bracket 23.

[0038] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
