Description
Technical Field
[0001] The utility model belongs to the technical field of lost foam casting, and in particular relates to a vibrating sand screening machine for lost foam casting with a multi-layer screening structure. Background Art
[0002] The vibrating sand screening machine for mold casting, especially in the field of lost foam casting, is a device dedicated to screening and preliminary processing of the molding sand used in the casting process. Its main function is to separate impurities, large particles and materials that do not meet the particle size requirements from the molding sand through vibration, so as to ensure that the quality and performance of the molding sand meet the requirements of the casting process.
[0003] However, traditional vibrating sand screening machines for lost foam casting often use single-layer screens for screening, which limits the ability to process materials of multiple particle sizes at the same time, resulting in low screening efficiency. Due to the lack of a multi-layer screening structure, traditional devices often find it difficult to meet high-precision requirements in screening accuracy, and particle size mixing is prone to occur. Traditional devices usually rely on manual screening operations, which not only increases the complexity of the operation, but also increases labor intensity.
[0004] Therefore, a vibrating sand screening machine for lost foam casting with a multi-layer screening structure is designed to solve the above problems. Utility Model Content
[0005] To solve the problems raised in the above background technology. The utility model provides a vibrating sand screening machine for lost foam casting with a multi-layer screening structure. The multi-layer screening structure of the screening component allows screening operations of different particle sizes to be carried out simultaneously. The first screen can be used to remove large-particle impurities, while the second screen further subdivides the particle size, thereby improving the overall screening efficiency. Since the frequency of the first screen and the second screen is high and uniform, molding sand of different particle sizes can be separated more effectively, reducing the proportion of mixed particles and improving the screening accuracy. By designing the first screen and the second screen with different aperture sizes, the screening results can be accurately controlled to meet the separation of molding sand with different particle size requirements. The design of the vibrating screen helps to reduce the clogging of the screen holes, because the vibration can make the material stuck in the screen holes jump out and keep the screen unobstructed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: a screening component is added to the present application, and the multi-layer screening structure of the screening component allows screening operations of different particle sizes to be performed simultaneously.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] like Figure 1 As shown;
[0026] A vibrating sand screening machine for lost foam casting with a multi-layer screening structure comprises a mounting frame 1.
[0027] In this embodiment: traditional devices often use a single-layer screen for screening, which limits the ability to process materials of multiple particle sizes at the same time, resulting in low screening efficiency. Due to the lack of a multi-layer screening structure, traditional devices often find it difficult to meet high-precision requirements in screening accuracy, and particle size mixing is prone to occur. Traditional devices usually rely on manual screening operations, which not only increases the complexity of the operation, but also increases labor intensity. In order to solve this technical problem, a screening component 2 is added on this basis.
[0028] More specifically:
[0029] like Figures 1 to 5 As shown:
[0030] In combination with the above content: the screening assembly 2 includes a first elastic plate 21, a first screen 22 and a motor 23. A plurality of first elastic plates 21 are fixedly connected to the inner side of the top of the mounting frame 1, and the inner side of the end of the first elastic plate 21 is fixedly connected to the first screen 22. Two motors 23 are installed on the outer sides of both ends of the first screen 22. The outer side of the main shaft of the motor 23 is fixedly connected to a rotating disk 24. One side of the rotating disk 24 is rotatably connected to a connecting arm 25. The outer side of the end of the connecting arm 25 is rotatably connected to the outer side of one end of the second screen 26. The outer sides of both ends of the second elastic plate 27 are respectively fixedly connected to the outer side of the end of the first screen 22 and the outer side of the end of the second screen 26. The first elastic plate 21 and the second elastic plate 27 are both made of elastic material. A feeding hopper 28 is fixedly connected to the upper surface of the mounting frame 1, and a primary screening plate 29 is fixedly connected to the inner side of the feeding hopper 28. A through groove is provided on the upper surface of the mounting frame 1, and the mounting frame 1 is communicated with the upper surface of the first screen 22.
[0031] In this embodiment: when the user uses the device, the device can be moved to a designated position. At this time, the user can inject the material to be screened into the feed hopper 28, and the material can be preliminarily screened through the primary screening plate 29. At this time, the material is injected into the first screen 22 through the upper surface of the mounting frame 1. The user can start the motor 23, and the rotating disk 24 outside the main shaft at the bottom end of the motor 23 rotates. While the rotating disk 24 rotates, it will pull and push the second screen 26 back and forth through the connecting arm 25. While pushing the second screen 26, the second screen 26 drives itself and the first screen 22 through the second elastic plate 27 and the first elastic plate 21 to continuously vibrate. The first screen 22 will screen the material again during the vibration process, and the screened material falls into the inside of the second screen 26. The second screen 26 will enter the second screen 26 again while vibrating. After screening, the final material can be discharged again through the second screen 26. Users can customize the different sieve hole sizes between the first screen 22 and the second screen 26 according to their own needs. The multi-layer screening structure of the screening component 2 allows screening operations of different particle sizes to be performed simultaneously. The first screen 22 can be used to remove large particles of impurities, while the second screen 26 further subdivides the particle size, thereby improving the overall screening efficiency. Since the frequency of the first screen 22 and the second screen 26 is high and uniform, molding sand of different particle sizes can be separated more effectively, reducing the proportion of mixed particles and improving the screening accuracy. By designing the first screen 22 and the second screen 26 with different aperture sizes, the screening results can be accurately controlled to meet the separation of molding sand with different particle size requirements. The design of the vibrating screen helps to reduce the blockage of the screen holes because the vibration can make the material stuck in the screen holes jump out and keep the screen unobstructed.
[0032] Going further:
[0033] In an optional embodiment, a receiving tray 210 is slidably connected to the inner side of the bottom end of the mounting frame 1 .
[0034] In this embodiment: the design of the receiving tray 210 allows the screening process and the collection process to be seamlessly connected, and the screened material can fall directly into the receiving tray 210, reducing the manual handling process and improving the continuous operation capacity of the entire production line. When the receiving tray 210 is full of material, it can be quickly slid out from the bottom of the device and replaced with a new receiving tray 210, thereby saving cleaning and preparation time and improving production efficiency.
[0035] Going further:
[0036] In an optional embodiment, the inner side of the bottom end of the receiving tray 210 is rotatably connected to a rolling rod 211 , and the outer side of the rolling rod 211 is in contact with the inner side of the bottom end of the mounting frame 1 .
[0037] In this embodiment: the design of the rolling rod 211 allows the receiving tray 210 to slide easily when it needs to be pulled out or pushed in, without the need for laborious carrying or dragging, which greatly improves the convenience of operation. In a production line or experimental environment, time is efficiency. The design of the rolling rod 211 makes the replacement and cleaning process of the receiving tray 210 faster, thereby saving valuable time.
[0038] Working principle: When the user uses the device, he can move the device to the designated position. At this time, the user can inject the material to be screened into the feed hopper 28, and the material can be preliminarily screened through the primary screening plate 29. At this time, the material is injected into the first screen 22 through the upper surface of the mounting frame 1. The user can start the motor 23, and the rotating disk 24 outside the main shaft at the bottom of the motor 23 rotates. While the rotating disk 24 rotates, it will reciprocate and pull and push the second screen 26 through the connecting arm 25. While pushing the second screen 26, the second screen 26 passes through the second elastic plate 27 and the first elastic plate The driver 21 and the first screen 22 vibrate continuously. The first screen 22 will screen the material again during the vibration process, and the screened material will fall into the inside of the second screen 26. The second screen 26 will screen again while vibrating, and the final material can be discharged again through the second screen 26. The user can customize the different sieve hole sizes between the first screen 22 and the second screen 26 according to their needs. The multi-layer screening structure of the screening component 2 allows screening operations of different particle sizes to be performed simultaneously. The first screen 22 can be used to remove large particles of impurities, while the second screen 26 further subdivides the particle size. Thereby, the overall screening efficiency is improved. Since the frequency of the first screen 22 and the second screen 26 is high and uniform, the molding sand of different particle sizes can be separated more effectively, the proportion of mixed particles is reduced, and the screening accuracy is improved. By designing the first screen 22 and the second screen 26 with different aperture sizes, the screening results can be accurately controlled to meet the separation of molding sand with different particle size requirements. The design of the vibrating screen helps to reduce the clogging of the screen holes, because the vibration can make the materials stuck in the screen holes jump out, keeping the screen mesh unobstructed. The design of the receiving tray 210 makes the screening process and the collection process seamlessly connected, and the screened materials can directly fall into the receiving tray 2 10, the manual handling process is reduced and the continuous operation capacity of the entire production line is improved. When the receiving tray 210 is full of materials, it can be quickly slid out from the bottom of the device and replaced with a new receiving tray 210, thereby saving cleaning and preparation time and improving production efficiency. The design of the rolling rod 211 allows the receiving tray 210 to slide easily when it needs to be pulled out or pushed in, without the need for laborious handling or dragging, which greatly improves the convenience of operation. In a production line or experimental environment, time is efficiency. The design of the rolling rod 211 makes the replacement and cleaning process of the receiving tray 210 faster, thereby saving valuable time.
