Description

Technical Field

[0001] This disclosure relates to the field of material sorting, specifically to a jetting assembly, jetting device, and sorting machine. Background Technology

[0002] In material sorting scenarios, such as plastic sorting, a blower system is often required to separate the materials. The blower body and cylinder are generally designed as separate units. This structure not only occupies a large installation space, resulting in poor overall equipment compactness, but its complex manufacturing process also increases the number of parts, significantly raising production costs. Furthermore, the installation process of the separate structure is cumbersome, requiring a specialized fixing frame for connection, increasing installation difficulty and maintenance costs. During equipment operation, due to the numerous connection points, sealing is difficult to guarantee, resulting in poor protection and potential gas leaks, affecting the normal operation and efficiency of the system, and consequently impacting material sorting efficiency and output.

[0031] The following describes specific embodiments of this disclosure. It should be noted that, in order to provide a concise description, this specification cannot exhaustively describe all features of the actual embodiments. It should be understood that, in the actual implementation of any embodiment, just as in any engineering or design project, various specific decisions are often made to achieve the developer's specific goals and to meet system-related or business-related constraints, and this can change from one embodiment to another. Furthermore, it is understood that although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content of this disclosure, some design, manufacturing, or production modifications based on the technical content disclosed in this disclosure are merely conventional technical means and should not be construed as insufficient content of this disclosure.

[0033] In some material sorting scenarios, such as plastic sorting, the blowing body and air distribution cylinder in some related technologies are separated. These independent components often occupy a large space, and the separate structure involves the manufacturing of multiple independent parts. The high precision required for the fit between these parts leads to complex processing procedures, extending the production cycle and significantly increasing costs for raw materials, processing, and assembly. Furthermore, during equipment installation, a dedicated frame must be built to connect both components to other equipment, which is not only cumbersome but also requires repeated disassembly and reassembly of multiple parts for later maintenance, consuming significant manpower and time. Moreover, the separate structure has numerous connection gaps, making protection difficult to guarantee, easily leading to gas leaks, reduced system efficiency, and even safety hazards.

[0034] In some scenarios, a sorting machine may include: a conveying device, an identification device, etc. The conveying device, such as a chute or belt, can be used to transport materials; the identification device can be used to identify the material being transported by the conveying device to determine its category. The blowing device may include blowing components and nozzle devices.

[0035] To overcome the problems existing in related technologies, exemplary embodiments of this disclosure provide a spraying assembly 100, such as...

The multiple mounting plates 120 can be flat and made of metal, with sufficient strength and rigidity to support components such as the solenoid valve 130. There can be at least four mounting plates 120, and there can be five. The mounting plates 120 can be fixed to the inside of the front panel 111 of the housing 110 or to the outside of the front panel 111 of the housing 110, and can be set at the mounting window 112 of the front panel 111, matching the position and outline of the mounting window 112.

The number, diameter, and layout of the mounting holes 121 are adapted to the air outlet of the solenoid valve 130, so as to expose the air outlet of the solenoid valve 130 in the mounting window 112. The mounting plate 120 can be fixed to the inside of the front side plate 111 of the housing 110 by means of bolts or other means, which can ensure that the mounting plate 120 is fixedly connected to the front side plate 111.

[0038] Multiple solenoid valves 130, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 As shown, each solenoid valve 130 can be installed on the mounting plate 120. The air outlet of the solenoid valve 130 can be located at the mounting hole 121 and exposed through the mounting window 112.

The outer side of the valve body of the solenoid valve 130 may be provided with a mounting flange or a threaded portion, which can cooperate with the mounting plate 120. The solenoid valve 130 can be fixed to the mounting plate 120 by bolts around the valve body. There can be at least eight or ten solenoid valves 130 installed on the mounting plate 120. Each solenoid valve 130 can have at least six or eight air outlets. The air outlets of the solenoid valves 130 can face the mounting hole 121 and be exposed through the mounting window 112 for easy connection with the nozzle device.

[0039] Multiple first gas lines 140, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, it can be connected to the air inlet of the corresponding solenoid valve 130. The first gas pipeline 140 can be a tubular structure. Both ends of the pipeline can be provided with connection interfaces matching the air inlet of the solenoid valve 130 and the air outlet of the gas distribution cylinder device 150, respectively, allowing connection to the solenoid valve 130 and the gas distribution cylinder device 150. One end of the first gas pipeline 140 can be detachably connected to the air inlet of the solenoid valve 130 via a connection interface (e.g., quick-connect type direct insertion, or threaded tightening), forming a sealed connection. The other end is connected to the corresponding air outlet of the gas distribution cylinder device 150. The number of air outlets of the gas distribution cylinder device 150 is the same as the number of outlets of the first gas pipeline 140, enabling one-to-one gas supply.

[0040] 150 cylinder distribution unit Figure 5 , Figure 6 , Figure 8 , Figure 9 It can be fixed inside the housing 110, can be connected to the first gas pipeline 140, and can be used to supply gas to the solenoid valve 130 through the first gas pipeline 140. The gas distribution cylinder device 150 can be a hollow cavity structure, which can be cylindrical or cuboid in shape, and made of metal (such as aluminum alloy, stainless steel, etc.), with a smooth inner wall and a flow guiding structure to balance the gas pressure. The gas distribution cylinder device 150 can be provided with a main air inlet for connecting to an external gas source pipeline; multiple air outlets can be distributed on the pipeline, the number of which can correspond to the number of the first gas pipeline 140, and the specifications of the air outlets can match the connection interface of the first gas pipeline 140 (such as quick connectors, threaded interfaces). The outer wall of the gas distribution cylinder device 150 can be provided with a fixing bracket or clamp to ensure that the gas distribution cylinder device 150 is fixed inside the housing 110, and can be detachably connected to the housing 110 to form a rigid fixation. The main air inlet of the cylinder distribution device 150 can be connected to an external air source (such as an air compressor) through the main gas pipeline; each air outlet can be connected to the corresponding solenoid valve 130 inlet through the first gas pipeline 140, so as to supply air to the solenoid valve 130.

[0041] In this embodiment, the spray assembly 100 integrates components such as the solenoid valve 130, the first gas pipeline 140, and the gas distribution cylinder device 150 into a single unit via a housing 110. This results in a compact and orderly structure, avoiding the space waste and chaotic pipeline issues associated with traditional split structures. The modular mounting plate 120 enables precise positioning of the solenoid valve, simplifying the manufacturing process and reducing the number of parts, making installation and maintenance more convenient. During maintenance, fault points can be quickly located, and the solenoid valve 130 can be quickly disassembled and replaced. The solenoid valve can be fixed to the housing 110 via the mounting plate 120. When a different model of solenoid valve 130 needs to be replaced, only the new mounting plate 120 needs to be replaced, reducing costs, facilitating installation and maintenance, improving protection, and increasing durability. This, in turn, improves the air spraying effect of the spraying device, enabling efficient material sorting and increasing material sorting output.

[0042] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, the cylinder distribution device 150 may include: a main pipe 151, one or more first intake pipes 152, and multiple second gas lines 153.

[0043] Main pipe 151, such as Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, it can be installed inside the housing 110. The main pipe 151 can be installed horizontally. The main pipe 151 can be a hollow tubular or cavity structure, with a cross-sectional shape that can be circular or square, and the material can be a high-pressure resistant metal, such as aluminum alloy or stainless steel. One end or the middle of the main pipe 151 can be provided with a main air inlet for connecting to the first air inlet pipe 152; multiple air outlets can be evenly distributed around the circumference or side, with the number of air outlets corresponding one-to-one with the second gas pipe 153, and the interface specifications can be matched with the second gas pipe 153 (such as threaded interface or quick-connect interface). The main pipe 151 can be fixed inside the housing 110 by means of a fixing bracket or clamp.

[0044] One or more first intake pipes 152, such as Figure 5 , Figure 6 , Figure 8 , Figure 9As shown, one end of the first intake pipe 152 can be connected to the main pipe 151 and can be used to supply gas to the main pipe 151. The first intake pipe 152 can be a hollow tubular structure, and the material can be the same as that of the main pipe 151. One end can be provided with a connection interface (such as a flange interface, quick-connect coupling, or threaded coupling) that matches the main intake port of the main pipe 151. It can adopt a detachable or fixed connection method to ensure that the gas can be sealed and input into the cavity of the main pipe 151. The other end can be provided with a universal interface that matches the external gas source pipeline. A sealing ring or sealing groove can be provided at the interface to ensure airtightness. There can be one, two, or more first intake pipes 152.

[0045] Multiple second gas lines 153, such as Figure 5 As shown, one end of the second gas pipeline 153 can be connected to the main pipeline 151, and the other end can be connected to the corresponding first gas pipeline 140. The second gas pipeline 153 can be a hollow tubular component, and its material can be the same as that of the main pipeline 151 and the first gas pipeline 140, using high-pressure resistant metals (such as stainless steel, aluminum alloy, etc.). Both ends can be equipped with connection interfaces (such as quick-connect fittings, threaded fittings, or flange interfaces) that match the gas outlet of the main pipeline 151 and the first gas pipeline 140, respectively. The number of second gas pipelines 153 can be the same as the number of first gas pipelines 140. The second gas pipelines 153 can transport gas from the main pipeline 151 to the first gas pipeline 140, facilitating gas supply to the solenoid valve 130.

[0046] In this embodiment, by setting a main pipe 151, one or more first air inlet pipes 152, and multiple second gas pipelines 153, gas can enter from the first air inlet pipe 152 into the main pipe 151 and from the main pipe into the second gas pipelines 153, which can supply gas to the solenoid valve 130. The gas supply to each component is uniform, the installation is simple, the reliability is high, the structure is compact, the layout is appropriate, which can save space, reduce costs, facilitate installation and disassembly, and further improve the air spraying effect of the spraying device, thereby improving the efficiency and output of material sorting.

[0047] In some embodiments, such as Figure 3 , Figure 6 , Figure 11 , Figure 12 , Figure 13 , Figure 14As shown, the housing 110 may be provided with one or more air inlets 113 corresponding to the first air inlet pipe 152, which can communicate with the first air inlet pipe 152 and be used to supply gas to the first air inlet pipe 152. The air inlets 113 can be through-hole structures penetrating the wall of the housing 110, and can be located on the side plate, top plate, or other suitable positions of the housing 110. The number of inlets can be consistent with the number of first air inlet pipes 152, and the diameter of the inlets can match the outer diameter of the first air inlet pipe 152. The interior of the air inlets 113 may have threaded sections, quick-connect fitting mounting grooves, or flange connection surfaces, which can be used for direct connection to the first air inlet pipe 152 or an external air source pipeline. An external air source can deliver gas to the first air inlet pipe 152 through the air inlets 113, so that the gas distribution cylinder device 150 can supply gas to the solenoid valve 130. In this embodiment of the disclosure, by providing one or more air inlets on the housing 110, it is convenient for an external air source to provide air to the cylinder distribution device 150 through the air inlet 113. The installation is simple, the reliability is high, the cost can be reduced, and the first air inlet pipe 152 of the cylinder distribution device 150 can be easily disassembled and installed. The operation is convenient and the durability is high.

[0048] In some embodiments, such as Figure 6 , Figure 8 , Figure 9 , Figure 10 As shown, the enclosure 110 may include multiple clamps 114, which can be installed at the bottom of the enclosure 110 to fix the main pipe 151. The clamps 114 can be arc-shaped or U-shaped metal plates, made of stainless steel or aluminum alloy, possessing corrosion resistance and sufficient mechanical strength. The clamps have fixing ears at both ends with bolt holes for fixing the main pipe 151. The clamps 114 can be evenly distributed on the inner wall of the bottom of the enclosure 110, and their number can match the length of the main pipe 151, ranging from four to six, or even four. Each clamp 114 corresponds to fixing a section of the main pipe 151. The clamps 114 can wrap around the outer surface of the main pipe 151, and the clamps can be tightened by tightening the bolts, thus fixing the main pipe 151 to the bottom of the enclosure 110. In this embodiment of the present disclosure, by providing multiple clamps at the bottom of the housing 110, the main pipe 151 can be fixed to the bottom of the housing 110, which can stably install the main pipe 151, avoid the main pipe 151 sagging or shaking and affecting the stability of gas flow, reduce cost, improve protection effect, make it more durable, facilitate the disassembly and assembly of the main pipe 151, and improve the stability of the spray assembly 100.

[0049] In some embodiments, such as Figure 3 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 15 As shown, the enclosure 110 may also include: a door panel 115, a mounting base 116, and a rotating handle 117.

[0050] Door panel 115, such as Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 14 , Figure 15 As shown, the door panel 115 can be hinged to the rear side of the housing 110, opposite to the front panel 111. The door panel 115 can be a flat component, made of the same material as the housing 110, with a thickness designed according to the dimensions of the housing 110. A sealing groove can be provided on the edge, and the overall dimensions can match the rear opening of the housing 110, allowing it to cover the internal space of the housing 110. One side of the door panel 115 can be hinged to the rear edge of the housing 110 via a hinge, hinge, or pin, and can be positioned opposite to the front panel 111. The hinge axis can be parallel to the height direction of the housing 110, allowing the door panel 115 to rotate and open around the rear edge. The door panel 115 can be fixed to the outer or inner wall of the rear side of the housing 110 using four to six hinges. One end of the hinge can be welded or bolted to the rear edge of the housing 110, and the other end can be fixed to the side of the door panel 115, forming a rotatable connection.

[0051] Fixture 116, such as Figure 3 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 15 As shown, it can be installed on the top of the outer side of the housing 110. The fixing base 116 can be a block or plate structure, can be a cuboid mechanism, and can be provided with a lock hole, threaded hole or snap-fit ​​platform, which can be used to lock with the door panel 115 in conjunction with the rotating handle 117. The bottom can be provided with a mounting surface and can be provided with fixing holes, which can be used to connect to the top of the outer side of the housing 110. Multiple fixing bases can be provided, from four to six, or four.

[0052] Rotate handle 117, as Figure 3 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 15As shown, the rotary handle 117 can be installed on the outer side of the door panel 115 and can be connected to the fixing seat 116. The rotary handle 117 can be a rod-shaped or handle-shaped component, and the rotary handle 117 can be connected and fixed to the lock hole or threaded hole of the fixing seat 116 by means of a latch or bolt. The rotary handle 117 can be installed on the outer side of the door panel 115 to realize the closing and locking of the door panel 115.

[0053] In this embodiment, a door panel 115 is provided on the rear side of the housing 110, and a rotating handle 117 is provided on the door panel 115. The door panel 115 can cooperate with the fixed base 116 to close the door panel 115, which can improve the flexibility and sealing of the overall component. The rotating handle 117 is also more convenient and simple to set, has better sealing, is not easily damaged, has a longer service life, is easy to install and maintain, has lower cost, improves the protection effect, and has higher durability.

[0054] In some embodiments, such as Figure 9 As shown, the enclosure 110 may further include a sealing strip 118, which can be disposed on the edge of the door panel 115 and used to seal the enclosure 110. The sealing strip 118 can be a slotted sealing strip, or a continuous elastic strip-shaped component with a rectangular or circular cross-section. The interior of the sealing strip 118 may have a hollow cavity or reinforcing ribs (such as metal wires or fiber bundles), and the edges may have lips or serrated protrusions to enhance sealing performance. The bottom may have a slot or an adhesive backing layer for fixing to the door panel 115. When the door panel 115 is closed, the sealing strip 118 can press against the sealing surface of the opening edge of the enclosure 110 to form a surrounding sealing boundary. When the handle 117 is rotated to lock, the pressure transmitted through the door panel 115 can cause the sealing strip 118 to undergo elastic deformation, filling the gap to achieve a seal. In this embodiment of the present disclosure, by providing a sealing strip 118 on the edge of the door panel 115, the box 110 can be sealed, which can prevent dust and moisture from entering the interior of the box 110, protect components such as the solenoid valve 130 and the air distribution cylinder device 150 from contamination, extend service life, reduce cost, improve protection effect, and enhance durability.

[0055] In some embodiments, such as Figure 8 , Figure 9 , Figure 10 , Figure 12As shown, the housing 110 can have multiple reinforcing ribs 119 inside, extending along the arrangement direction of the multiple solenoid valves 130. The reinforcing ribs 119 can be strip-shaped or rib-like structures, made of the same material as the housing 110, with a cross-section that can be right-angled, triangular, or arc-shaped, and can be installed along the inner wall of the housing 110. The reinforcing ribs 119 can be distributed on the top, bottom, and side walls inside the housing 110, and multiple ribs can be installed, extending parallel to the arrangement direction of the multiple solenoid valves 130 (e.g., horizontal or vertical) to form a linear support structure. The reinforcing ribs 119 can be welded to the inner wall of the housing 110 or integrally formed with the housing 110 to form a rigid connection. The extending direction of the reinforcing ribs 119 can be consistent with the direction of the mounting plate 120 of the solenoid valves 130 and the main pipeline 151 of the cylinder distribution device 150. In this embodiment, the internal reinforcement ribs 119 of the housing 110 can increase the rigidity of the housing 110 when densely packed components are installed, avoid stress concentration, provide reliable structural support for the long-term stable operation of the spray assembly 100, extend its service life, reduce costs, and effectively improve the protection effect.

[0056] Based on the same inventive concept, exemplary embodiments of this disclosure also provide a blowing device, which may include: the blowing assembly 100 and the nozzle device as described in the foregoing embodiments.

The jetting assembly 100 can mount the multiple solenoid valves 130 on the multiple mounting plates 120 and fix them to the housing 110.

[0058] The nozzle device can be connected to the air outlet of the solenoid valve 130 for spraying gas. The nozzle device can be installed outside the housing 110, and can be fixed to the solenoid valve 130 through the mounting window 112 of the front panel 111 of the housing 110. The nozzle orifice faces the material sorting area and can spray gas for material blowing. Multiple nozzle devices can be provided, matching the number of air outlets of the solenoid valve 130.

[0059] In this embodiment, by connecting the nozzle device to the air outlet of the solenoid valve 130, air can be sprayed through the nozzle device for sorting materials such as plastics. The solenoid valve 130, the first gas pipeline 140, and the air distribution cylinder device 150 can be integrated into a single unit using a housing 110, resulting in a compact and orderly structure that avoids the space waste and chaotic pipeline issues of traditional split structures. The modular mounting plate 120 enables precise positioning of the solenoid valve, simplifies the manufacturing process, reduces the number of parts, and makes installation and maintenance more convenient. During maintenance, fault points can be quickly located, and the solenoid valve 130 can be quickly disassembled and replaced. The solenoid valve can be fixed to the housing 110 using the mounting plate 120. When replacing with a different model of solenoid valve 130, only the new mounting plate 120 needs to be replaced, reducing costs, facilitating installation and maintenance, improving protection, and increasing durability. This, in turn, improves the air spraying effect of the spraying device, enabling efficient material sorting and increasing material sorting output.

[0060] In some embodiments, such as Figure 14 , Figure 15 As shown, the blowing device also includes: mounting base 200 and mounting bracket 300.

[0061] Mounting bracket 200, such as Figure 14 , Figure 15 As shown, it can be positioned below the jetting assembly 100 and can be used to install the jetting assembly 100. The mounting base 200 can be a plate-like or frame structure, and the mounting base 200 can be provided with multiple mounting holes for fixing the jetting assembly.

[0062] Mounting bracket 300, such as Figure 15 As shown, one end is connected to the bottom of the housing 110 on the side opposite to the mounting plate 120, and the other end is connected to the mounting base 200, which can be used to tilt the housing 110. The mounting bracket 300 can be a rod-shaped structure, consisting of a first connecting part 310, a second connecting part 320, and an intermediate support part 330. The first connecting part 310 can be fixed to the bottom of the housing 110 on the side opposite to the mounting plate 120 by bolt connection. The second connecting part 320 can be fixed to the mounting base 200 by bolt connection, etc. The intermediate support part 330 can be tilted, which can raise one side of the door panel 115 of the housing 110, making the housing 110 tilted. The tilt angle can be 15-25 degrees, or 20 degrees. Unlike conventional ore sorting, plastic sorting requires downward-sloping gas spraying to change the trajectory of the plastic due to its low weight. Materials passing through the identification device can be categorized. Plastics requiring blowing can be blown through the device, while those not requiring blowing do not. Therefore, different types of plastics can fall into different collection areas, achieving efficient plastic sorting.

[0063] In this embodiment, by providing a mounting bracket 300 on the mounting base 200, the mounting bracket 300 can be located on the side of the housing 110 away from the mounting plate 120, allowing the housing 110 to be tilted, which can ensure smooth gas pipeline and prevent water vapor interference, reduce costs, facilitate installation and maintenance, improve protection effect, and make it more durable, thereby improving the air spraying effect of the blowing device, enabling efficient material sorting and increasing the output of material sorting.

[0064] Based on the same inventive concept, exemplary embodiments of this disclosure also provide a sorting machine that can be used for material sorting, wherein the sorting machine may include: a conveying device and an identification device, such as the blowing device in the foregoing embodiments.

[0065] A conveying device is used to transport materials. Conveying devices can be conveyor belts, chutes, vibrating feeders, etc. Materials can be placed on the conveying device and transported to the identification device.

[0066] An identification device can be used to identify the type of material being transported by a conveyor.

[0067] The blowing device, which can be the blowing device in the foregoing embodiments, can be used to sort materials according to their category. The blowing device can be located downstream of the conveying device and can sort materials according to their category, thus separating different categories of materials from each other.

[0068] In this embodiment of the disclosure, a sorting machine is provided, which can transport materials via a conveying device to facilitate identification and classification by the identification device. Based on the identification and classification of materials by the identification device, different types of materials are finally sorted by a blowing device, which can accurately and quickly classify the materials to be tested, with high identification and sorting accuracy. The jetting assembly 100 in the jetting device integrates components such as the solenoid valve 130, the first gas pipeline 140, and the gas distribution cylinder device 150 into one unit through the housing 110. The structure is compact and the layout is orderly, avoiding the space waste and pipeline cross-contamination problems of traditional split structures. The modular mounting plate 120 can achieve precise positioning of the solenoid valve, simplifying the processing flow and reducing the number of parts, making installation and maintenance more convenient. During maintenance, the fault point can be quickly located, and the solenoid valve 130 can be quickly disassembled and replaced. The solenoid valve can be fixed on the housing 110 through the mounting plate 120. When it is necessary to replace other models of solenoid valve 130, only the new mounting plate 120 needs to be replaced, which can reduce costs, facilitate installation and maintenance, improve the protection effect, and make it more durable. In turn, it improves the air jetting effect of the jetting device, enabling efficient material sorting and increasing the output of material sorting.
