Description

Technical Field

[0001] This utility model relates to the field of vibration equipment technology, and more specifically to a vibration component and a packaging unpacking machine using the vibration component. Background Technology

[0002] Vibrating screens are commonly used screening equipment, widely applied in industries such as mining, building materials, and chemicals, for material grading, sorting, and impurity removal. With the development of industrial production, higher requirements are being placed on the screening efficiency, structural stability, and service life of vibrating screens.

[0003] Currently, common vibrating screens on the market mainly include linear vibrating screens, circular vibrating screens, and elliptical vibrating screens. Among them, linear vibrating screens typically use an eccentric shaft drive, where the rotation of the eccentric shaft drives the screen body to perform reciprocating linear motion, thereby achieving material screening. For example, Chinese patent document CN109692814A discloses a screening device and a packaging unpacking machine containing the screening device, in which the vibrating screen is located below the receiving port and is used to screen the material, achieving two screenings: bag breaking and material screening, thus improving the separation effect.

[0004] In the field of unpacking machines, vibrating screens are key components that play a decisive role in the screening quality of materials. For example, Chinese patent document CN215852319U discloses a filterable ton bag unpacking machine, in which the filtering device uses a vibrating screen, including a screen body and a filter screen, which can filter the material unloaded from the ton bag before conveying it to the silo, preventing impurities or large lumps in the material from being carried into the silo.

[0005] Traditional vibrating screens typically use eccentric shafts or exciters for their vibration components. For example, Chinese patent document CN118681786B discloses an ultra-large vibrating screen and a method for calculating its amplitude. This vibrating screen includes a screen body, multiple drive mechanisms, and multiple excitation mechanisms. It generates an elliptical excitation force through the exciter, which can prevent material jamming and improve the efficient transmission of the excitation force.

[0006] Regarding the driving method of vibrating screens, Chinese patent document CN108246604B discloses a semi-automatic intermittent feeding vibrating screen device, including a frame, feeding device, screen body, driving device, etc. It forms a three-degree-of-freedom motion through the combination of multiple driving devices, thereby improving the screening efficiency.

[0007] In addition, Chinese patent document CN214160417U discloses a vibrating screen, which includes a housing, a vibrating shaft installed on the upper part of the housing, a drive mechanism for driving the vibrating shaft to vibrate, and two vibrating screen bodies arranged in parallel. The vibrating shaft drives the screen bodies to move, thereby realizing material screening.

[0008] However, existing vibration components have the following problems: Firstly, traditional vibration components have complex structures and numerous parts, which not only increases manufacturing costs but also raises maintenance difficulties. Secondly, the connection between the vibration component and the vibrating screen is often inflexible, making it difficult to adapt to vibration requirements under different working conditions and affecting screening efficiency. Furthermore, existing vibration components have a single vibration direction, mostly horizontal or inclined, lacking effective vertical vibration, which causes some materials to easily accumulate on the screen surface, reducing screening efficiency.

[0009] Therefore, there is an urgent need for a vibrating component that is simple in structure, flexible in connection, and capable of providing effective vibration in the vertical direction, in order to improve the screening efficiency and service life of vibrating screens. Utility Model Content

[0044] In this embodiment, the first direction is along the X direction in the figure, and the second direction is along the Y direction in the figure.

[0045] In this embodiment, referring to the accompanying drawings, a vibration assembly includes a power unit 100, an eccentric unit 200, and a vibration support unit 300. The power unit 100 drives the eccentric unit 200 to reciprocate. The vibration support unit 300 includes a vibration mounting plate 310 connected to a vibrating screen 700, a vibration movable plate 320 movably engaged with the vibration mounting plate 310, and a vibration shaft 330 mounted on the vibration movable plate 320. The eccentric unit 200 is movably connected to the vibration shaft 330 via a support rod 400. The power unit 100 reciprocates to drive the eccentric unit 200 and causes the vibration movable plate 320 to lift the vibration mounting plate 310 in the vertical direction.

[0046] In some possible embodiments, the eccentric unit 200 includes an eccentric bearing 210 movably mounted on a vertical bearing seat. A transmission wheel 220, which drives the power unit 100, is connected to the outside of the eccentric bearing 210. An eccentric bearing seat 230 is provided outside the eccentric bearing 210, and the eccentric bearing seat 230 is movably connected to the vibration shaft 330 via a support rod 400. When the power unit 100 operates, the transmission wheel 220 drives the eccentric bearing 210 to rotate. Due to the eccentric characteristic of the eccentric bearing 210, the eccentric bearing seat 230 reciprocates, thereby driving the vibration shaft 330 up and down via the support rod 400, thus driving the vibrating movable plate 320.

[0047] In some possible embodiments, the vibration mounting plate 310 is installed at the lower part of the vibrating screen 700. The vibration mounting plate 310 includes vibration side plates 311 symmetrically mounted on both sides of the vibrating screen 700 along a first direction. A plurality of uniformly spaced vibration reinforcing plates 312 distributed along a second direction are disposed between the two vibration side plates 311. The top surface of each vibration reinforcing plate 312 is in contact with the bottom of the vibrating screen 700. This structural design allows the vibration mounting plate 310 to uniformly support the vibrating screen 700 and uniformly transmit vibration force to the vibrating screen 700, improving screening efficiency. In some embodiments, the top surface of each of the vibration reinforcing plates 312 is in contact with the bottom of the vibrating screen 700 through a sub-plate. This structural design allows the vibration mounting plate 310 to stably support the vibrating screen 700, while the vibration reinforcing plates 312 enhance the overall structural strength, ensuring structural stability during vibration.

[0048] In some possible embodiments, the vibrating movable plate 320 includes a base 321. The upper surface of the base 321 has a plurality of protrusions 322 that are movably engaged with the vibrating mounting plate 310 and distributed along a second direction. The lower surface of the base 321 has mounting portions 323 symmetrically arranged on both sides along a first direction for assembling the vibrating shaft 330. The protrusions 322 movably engage with the vibrating mounting plate 310, ensuring that the vibrating movable plate 320 can accurately drive the vibrating mounting plate 310 during movement without lateral displacement. The mounting portions 323 provide a stable mounting position for the vibrating shaft 330, ensuring that the vibrating shaft 330 can stably transmit the vibration force generated by the eccentric unit 200.

[0049] In some possible embodiments, this vibration assembly can be applied to a packaging unpacking machine. When the packaging unpacking machine is working, the power unit 100 starts, driving the eccentric bearing 210 to reciprocate through the transmission wheel 220. The eccentric bearing 210 generates eccentric motion, driving the eccentric bearing seat 230 to move. The eccentric bearing seat 230 drives the vibration shaft 330 to move through the support rod 400. The vibration shaft 330 drives the vibrating movable plate 320 to move. The protrusion 322 on the vibrating movable plate 320 is movably engaged with the vibrating mounting plate 310, causing the vibrating movable plate 320 to lift the vibrating mounting plate 310 in the vertical direction, thereby driving the vibrating screen 700 to vibrate. The vibration of the vibrating screen 700 loosens the packaged material, realizing the unpacking function. This structural design makes the packaging unpacking machine simple in structure, with good vibration effect and high unpacking efficiency.

[0050] In some possible embodiments, the unpacking machine also includes a frame 10, a crushing unit 500 mounted on the frame 10, a rolling unit 600 mounted on the frame 10 and cooperating with the crushing unit 500 through a discharge conduit 510, a vibrating screen 700 that is tilted and movably mounted on the frame 10 and located below the rolling unit 600, a support unit 800 mounted on the frame 10 and used to support the vibrating screen 700, and a blower discharge unit 900 disposed on the frame 10 and cooperating with the second discharge port 712 in the vibrating screen 700. The second support member in the support unit 800 abuts against the vibration mounting plate 310 in the vibration assembly.

[0051] In some possible embodiments, referring to the accompanying drawings, the crushing unit 500 includes a crushing blade holder box. Drive motors are respectively installed on both sides of the box, and the two drive motors are respectively connected to crushing blade shafts installed inside the crushing blade holder box. One crushing blade shaft is equipped with a plurality of first crushing blades arranged sequentially, and the other crushing blade shaft is correspondingly equipped with a plurality of second crushing blades that are sequentially staggered with the first crushing blades. A plurality of crushing teeth are evenly arranged on the outer circumference of the second crushing blades. The material is crushed by the cooperation of the first and second crushing blades with their corresponding drive motors. A discharge conduit 510 is installed at the bottom of the crushing blade holder box in the crushing unit 500. The discharge conduit 510 has a curved structure, and its other end extends into the inside of the roller 610 in the rolling unit 600 but is not in contact with the roller 610.

[0052] In some possible embodiments, the rolling unit 600 includes a roller unit 620 that supports and drives the roller 610. The roller unit 620 is mounted on the roller 610 and includes two sets of roller groups 621 disposed on the inner sides of the top of the frame 10. Each set of roller groups 621 includes two mating roller components 6210. The two roller components 6210 in one set of rollers 621 are connected to a drive motor 623 disposed on the frame 10 via a drive guide shaft 622. The drive motor 623 drives the roller components 6210 to rotate via the drive guide shaft 622, and the roller components 6210 in turn drive the roller 610 to rotate, thereby realizing the functions of material tumbling and conveying. Referring to the attached drawings, rollers 6210 are symmetrically arranged at both ends of the two inner sides of the upper part of the frame 10. The two rollers 6210 located on the rear side are connected to the drive motor 623 installed on the frame 10 and located below the crushing unit 500 through the drive guide shaft 622. Driven by the drive motor 623, the drum 610 is rotated.

[0053] In some possible embodiments, the roller 610 is a cylindrical structure. The inner sides of both ends of the outer circumference of the roller 610 are respectively connected to flange fixing plates 611 that are limited and matched with the roller assembly 621. The end of the roller 610 near the crushing unit 500 has a plurality of first discharge holes 612 evenly arranged along the axial direction of the cylindrical structure. Each first discharge hole 612 is located between the two flange fixing plates 611 and is connected to the flange fixing plate 611 near the crushing unit 500. The outer wall of the roller 610 has a plurality of second discharge holes 613 evenly arranged along its radial direction. Each second discharge hole 613 is located between the two flange fixing plates 611. The roller 610 is inclined and its inner wall is evenly provided with a plurality of blades 614 for guiding the flow. A protective cover 615 mounted on a support is provided above the roller 610. This design allows materials to be discharged through the first discharge hole 612 and the second discharge hole 613 during the rotation of the drum 610, while the blades 614 on the inner wall help the materials to tumble and guide, improving processing efficiency.

[0054] In some possible embodiments, the roller 610 is made of metal, possessing sufficient strength and wear resistance to withstand the impact and friction of materials. The flange fixing plate 611 on the outside of the roller 610 is firmly connected to the inner sides of both ends of the cylindrical structural member by welding or bolting, forming an integral structure. Alternatively, as shown in the figure, the flange fixing plate 611 can be composed of multiple identical structural members and welded to the outside of the roller 610. The outer edge of the flange fixing plate 611 cooperates with the idler roller assembly 621, enabling the roller 610 to rotate stably on the idler roller assembly 621, while limiting the axial displacement of the roller 610 and ensuring the operational stability of the roller 610.

[0055] The first discharge holes 612 are evenly arranged along the axial direction of the cylindrical structure, near one end of the crushing unit 500. The design of these holes allows the material processed by the crushing unit 500 to smoothly enter the drum 610. The first discharge holes 612 connect with the flange fixing plate 611 near the crushing unit 500, forming a continuous feeding channel to ensure that the material can smoothly enter the drum 610 from the crushing unit 500. The size and number of the first discharge holes 612 are designed according to the characteristics and processing capacity of the material being processed, ensuring sufficient feed volume without causing material blockage.

[0056] The second discharge holes 613 are evenly arranged along the radial direction of the drum 610 on its outer wall, located between the two flange fixing plates 611. The design of these discharge holes allows materials meeting the discharge conditions to exit the drum 610 through these holes, achieving the material classification function. The size of the second discharge holes 613 is smaller than that of the first discharge holes 612, ensuring that only fully processed materials with the required particle size can be discharged through these holes. The uniform distribution of the second discharge holes 613 ensures the uniformity of material discharge and improves classification efficiency.

[0057] The inclined design of the drum 610 allows the material to move from a high point to a low point along the inner wall of the drum 610 under the action of gravity, forming a natural material flow path. The design of the inclination angle takes into account the flowability and residence time of the material, ensuring that the material has sufficient processing time in the drum 610 while preventing the material from accumulating inside the drum 610.

[0058] The blades 614, evenly distributed on the inner wall of the drum 610, serve to guide and agitate the material. When the drum 610 rotates, these blades 614 lift the material to a certain height, allowing it to fall under gravity, forming a tumbling material flow. This enhances the interaction between materials and their contact with the inner wall of the drum 610, improving processing efficiency. The shape, size, and arrangement of the blades 614 are optimized to effectively agitate the material without causing blockage or damage to the drum 610.

[0059] A protective cover 615, mounted on a support frame, is installed above the drum 610 to protect and enclose the entire drum 610. The protective cover 615 prevents dust and splashes from escaping during processing, improving the working environment, and also prevents external debris from falling into the drum 610, ensuring the purity of the processed materials. The protective cover 615 is made of lightweight yet robust materials, facilitating installation and maintenance, while possessing sufficient strength to withstand potential impacts.

[0060] In some possible embodiments, the vibrating screen 700 includes a screen body 710 that is movably inclined. At the end of the screen body 710 away from the crushing unit 500, two sets of first discharge ports 711 and second discharge ports 712 are arranged side-by-side and distributed along a second direction. A gate 713 is inclinedly arranged on the screen body 710 to separate the first discharge ports 711 and second discharge ports 712. A first discharge hopper 714 for discharging material to the side of the frame 10 is connected to the first discharge port 711 of the screen body 710. Inside the screen body 710, there is a mesh screen 715 that is not in contact with the bottom surface of the screen body 710 and has at least one layer. The first discharge port 711 is located below the mesh screen 715, and the second discharge port 712 is not below the mesh screen 715. This design allows materials to be separated on the vibrating screen 700 according to particle size. Small particles fall through the mesh screen 715 and are discharged through the first discharge port 711, while large particles are discharged from the second discharge port 712.

[0061] The vibrating screen 700 has a rectangular screen body 710 with an overall inclined design. The inclination angle can be adjusted between 5 and 30 degrees to adapt to the screening requirements of different materials. The screen body 710 is made of high-strength steel, possessing sufficient rigidity and wear resistance to withstand the impact of prolonged vibration operation. The screen body 710 is connected to the frame 10 via a support unit 800, enabling the screen body 710 to vibrate relative to the frame 10. In this embodiment, the support unit 800 includes a first support member and a second support member with identical structures. Both the first and second support members are inclinedly mounted on the frame 10. As shown in the attached drawings, both the first and second support members include a vibration connecting lower seat connected to a bracket. Inclined support plates are connected to both ends of the vibration connecting lower seat, and the upper parts of the two support plates are connected to the vibration connecting seat. The vibration connecting seat abuts against the bottom surface of the screen body 710. In the second support member, the vibration connecting seat abuts against the vibration reinforcing plate 312 in the vibration mounting plate 310.

[0062] At the end of the screen body 710 furthest from the crushing unit 500, i.e., the right end of the screen body 710 (see attached diagram), two sets of parallel discharge ports are provided, namely the first discharge port 711 and the second discharge port 712. These two discharge ports are distributed along a second direction (i.e., the width direction of the screen body 710) and are arranged parallel to each other. The dimensions of the first discharge port 711 and the second discharge port 712 can be adjusted according to actual screening requirements. Typically, the width of the first discharge port 711 is 20%-60% of the width of the screen body 710, and the width of the second discharge port 712 is also 20%-60% of the width of the screen body 710.

[0063] Additionally, a gate 713 is inclinedly installed on the right end side plate of the screen body 710. This gate 713 is used to separate the first discharge port 711 and the second discharge port 712. The gate 713 is made of wear-resistant steel plate, and its angle with the inclined direction of the screen body 710 ranges from 110° to 150°, but the inclination angle can be adjusted independently to control the material distribution ratio. The upper end of the gate 713 is fixedly connected to the inner wall of the screen body 710, and the lower end is suspended, forming a guide surface to guide the material to flow to the first discharge port 711 and the second discharge port 712 respectively. The height and inclination angle of the gate 713 are adjustable, thereby changing the material distribution ratio of the two discharge ports.

[0064] In some possible embodiments, a first discharge hopper 714 is connected to the first discharge port 711 of the screen body 710. The discharge hopper extends towards the side of the frame 10 and is shown in the figure tilted downwards towards the front, for guiding the screened material to the side of the frame 10. The upper and lower openings of the first discharge hopper 714 are matched with the dimensions of the first discharge port 711 to facilitate the centralized discharge of ash material.

[0065] In some possible embodiments, a mesh screen 715 is disposed inside the screen body 710. The mesh screen 715 is not in contact with the bottom surface of the screen body 710 and can be fixed inside the screen body 710 by multiple support frames. One or more mesh screens 715 can be disposed. When multiple layers are disposed, the meshes are not in contact. In some embodiments, the aperture of each layer of mesh screen 715 decreases sequentially from top to bottom to achieve multi-stage screening of materials. In some embodiments, the aperture of each layer of mesh screen 715 is consistent to ensure that the screen body 710 has good wear resistance and screening efficiency.

[0066] The first discharge port 711 is located below the screen 715 and is used to discharge fine materials that have been screened by the screen 715. These materials fall through the holes of the screen 715 to the bottom of the screen body 710, and then are discharged through the first discharge port 711 and the first discharge hopper 714. The second discharge port 712 is not located below the screen 715; it is located at the end of the screen 715 and is used to discharge larger particles that have not passed through the screen 715. These materials move along the surface of the screen 715 under vibration and are eventually discharged from the second discharge port 712.

[0067] In some possible embodiments, the blower discharge unit 900 includes a blower 910 and an air box 920. The air box 920 includes an air inlet assembly 921 for supporting and communicating with the blower 910, and a discharge assembly 922 that cooperates with the second discharge port 712 in the vibrating screen 700. The air inlet assembly 921 and the discharge assembly 922 are internally connected. The side of the discharge assembly 922 is provided with an inclined discharge port 9221 for discharging material to the side of the frame 10. A vertically adjustable air box adjusting plate 9222 is movably installed at the front discharge port of the discharge assembly 922. The airflow generated by the blower 910 enters the air box 920 through the air inlet assembly 921, and then cooperates with the second discharge port 712 of the vibrating screen 700 through the discharge assembly 922 to help the material be discharged smoothly. The air box adjusting plate 9222 can adjust the airflow direction and intensity to optimize the material conveying effect.

[0068] During operation, the power unit 100 drives the eccentric unit 200 to reciprocate. The eccentric unit 200, through the support rod 400, drives the vibrating shaft 330 to move up and down. The vibrating shaft 330 drives the vibrating movable plate 320 to vertically lift the vibrating mounting plate 310, thereby causing the vibrating screen 700 connected to the vibrating mounting plate 310 to vibrate, thus realizing the material screening function. This vibrating component has a simple structure, high transmission efficiency, and good vibration effect, which can effectively improve the working efficiency and screening quality of the unpacking machine.
