Description

Technical Field

[0001] This utility model relates to the field of material processing technology, and more specifically, to a suction gun lifting mechanism and a suction device. Background Technology

[0002] Existing material gun lifting devices generally use either cylinders or screws to lift the material gun. During use, when cylinders lift the material gun, the uneven torque can cause the cylinder to jam, resulting in the material gun shaking and making it difficult to stop accurately. When screws lift the material gun, the complex structure and direct contact friction between the screw and nut can generate iron filings that can enter the raw materials, contaminating them and affecting product quality. Utility Model Content

[0003] The main purpose of this utility model is to provide a suction gun lifting mechanism and suction device to solve the problem that the existing suction gun lifting mechanism is prone to generating iron filings that contaminate raw materials.

[0004] To achieve the above objectives, according to one aspect of the present invention, a suction gun lifting mechanism is provided, comprising: a fixed frame disposed outside the suction hopper; a sliding frame, the sliding frame being vertically and vertically disposed relative to the fixed frame; a suction gun, the suction gun being mounted on the sliding frame and moving vertically and vertically synchronously with the sliding frame; and a drive assembly, the drive assembly being drivenly connected to the sliding frame, driving the sliding frame and the suction gun to move vertically and vertically as a whole.

[0005] Furthermore, the drive assembly includes: a drive member connected to the fixed frame, the output end of the drive member having a synchronous pulley; and a synchronous belt, both ends of the synchronous belt being connected to the sliding frame, and the synchronous belt engaging with the synchronous pulley, the drive member driving the sliding frame to move up and down via the synchronous belt.

[0006] Furthermore, the drive assembly also includes a guide wheel, which is rotatably mounted on the drive member, and the timing belt is wound around the outside of the guide wheel.

[0007] Furthermore, there are multiple guide wheels, and guide wheels are provided on both sides of the synchronous wheel along the length of the synchronous belt.

[0008] Furthermore, the suction gun lifting mechanism also includes a guide assembly, which includes a slider and a guide rail. One of the slider and the guide rail is located on a fixed frame, and the other of the slider and the guide rail is located on a sliding frame. The guide rail extends longitudinally, and the fixed frame and the sliding frame slide relative to each other through the guide assembly.

[0009] Furthermore, the suction gun lifting mechanism also includes a bellows cover, the two ends of which are connected to the sliding frame and the fixed frame respectively, and the bellows cover is located on the outside of at least a part of the drive assembly.

[0010] Furthermore, the top of the sliding frame has a first accordion cover mounting plate, and the fixed frame has a second accordion cover mounting plate. The second accordion cover mounting plate is located below the first accordion cover mounting plate, and the top and bottom ends of the accordion cover are connected to the first accordion cover mounting plate and the second accordion cover mounting plate, respectively.

[0011] Furthermore, the sliding frame includes a first segment and a second segment that are bent and connected in sequence. The first segment extends laterally, the second segment extends longitudinally, the drive assembly is located in the second segment, and the first segment has a mounting hole through which the suction gun is rotatably inserted.

[0012] Furthermore, the suction gun includes: a suction section having a cavity and a suction head; a connecting pipe connected to the suction section and used for external connection; and a clamping member having the suction section passing through a mounting hole, the clamping member being located on the outer periphery of the suction section and connected to a sliding frame to clamp the suction section at the mounting hole.

[0013] According to another aspect of the present invention, a material suction device is provided, including a material suction frame and the aforementioned material suction gun lifting mechanism. The material suction frame has a material suction bin for accommodating ton bags. The material suction gun lifting mechanism is vertically and vertically arranged above the material suction frame, and the material suction gun of the material suction gun lifting mechanism can be lowered and extended into the material suction bin to suction material.

[0014] By applying the technical solution of this utility model, a sliding frame, a suction gun, and a drive assembly are set on a fixed frame. These components cooperate to achieve the lifting and lowering movement of the suction gun, thereby completing the suction operation. Specifically, the fixed frame serves as the basic support for the entire suction gun lifting mechanism, ensuring stability. Because the fixed frame is located outside the suction chamber, most components do not extend into the chamber to avoid contaminating the raw materials. The sliding frame is positioned opposite the fixed frame and can move up and down along it. The suction gun, as the core of the entire mechanism, is fixedly connected to the sliding frame, forming a stable, integrated structure. This allows the suction gun to move synchronously when the sliding frame moves up and down. The drive assembly is the key component for lifting the suction gun. It includes a drive component and a conveyor belt. The drive component is fixed to the fixed frame to ensure stability and precise drive control. The conveyor belt is driven by the drive component; rotation of the drive component drives the conveyor belt, thereby achieving the overall lifting and lowering movement of the sliding frame and the suction gun. The above design optimizes the lifting control of the suction gun, enabling precise positioning, smooth lifting, and efficient material suction. On the other hand, the belt drive method has higher transmission efficiency, less friction and wear compared to traditional cylinder or screw drives, while avoiding the problem of iron filings contaminating raw materials.

[0024] To address the problem that existing suction gun lifting mechanisms easily generate iron filings that contaminate raw materials, this utility model provides a suction gun lifting mechanism and a suction device.

[0025] like Figure 1 and Figure 2As shown, the suction gun lifting mechanism in this embodiment includes: a fixed frame 10, a sliding frame 20, a suction gun 30, and a drive assembly 40 disposed outside the suction hopper 70; the sliding frame 20 is vertically and vertically disposed relative to the fixed frame 10; the suction gun 30 passes through the sliding frame 20 and moves up and down synchronously with the sliding frame 20; the drive assembly 40 includes a drive component 41 and a conveyor belt, the drive component 41 is connected to the fixed frame 10, the conveyor belt is drivenly connected to the drive component 41, and the drive component 41 drives the sliding frame 20 and the suction gun 30 to move up and down as a whole through the conveyor belt.

[0026] In this embodiment, a sliding frame 20, a suction gun 30, and a drive assembly 40 are arranged on a fixed frame 10. These components cooperate to achieve the lifting and lowering movement of the suction gun 30, thereby completing the suction operation. Specifically, the fixed frame 10 serves as the basic support for the entire suction gun lifting mechanism, ensuring stability. Since the fixed frame 10 is located outside the suction chamber 70, most components do not extend into the suction chamber 70 to avoid contaminating the raw materials. The sliding frame 20 is positioned opposite the fixed frame 10 and can move up and down along it. The suction gun 30 is the core component of the entire mechanism, fixedly connected to the sliding frame 20, forming a stable, integrated structure. Thus, when the sliding frame 20 moves up and down, it drives the suction gun 30 to move up and down synchronously. The drive assembly 40 is the key component for realizing the lifting and lowering of the suction gun 30. It includes a drive component 41 and a conveyor belt. The drive component 41 is fixed on the fixed frame 10 to ensure its stability and precise drive control. The conveyor belt is driven by the drive component 41. The rotation of the drive component 41 drives the conveyor belt, thereby realizing the overall lifting and lowering movement of the sliding frame 20 and the suction gun 30. This design optimizes the lifting and lowering control of the suction gun 30, achieving precise positioning, smooth lifting and lowering, and efficient material suction. Furthermore, compared to traditional cylinder or screw drives, belt drive has higher transmission efficiency, less friction and wear, and avoids the problem of iron filings contaminating the raw materials.

[0027] like Figure 2As shown, in this embodiment, the drive unit 41 can be a drive motor. The output end of the drive unit 41 has a synchronous pulley 411, which is fixed on the output shaft of the drive unit 41. The synchronous pulley 411 is a toothed pulley. Correspondingly, the conveyor belt is a synchronous belt 42, and the tooth profile of the synchronous belt 42 and the tooth profile of the synchronous pulley 411 need to be precisely matched to achieve non-slip transmission. The two ends of the synchronous belt 42 are respectively connected to the fixed points on the sliding frame 20 to form a closed-loop transmission. In this way, when the drive motor starts, the output shaft drives the synchronous pulley 411 to rotate, and the tooth profile on the synchronous pulley 411 drives the synchronous belt 42 to move. Due to the connection between the synchronous belt 42 and the sliding frame 20, the sliding frame 20 moves up and down accordingly, realizing the precise positioning and stable lifting of the suction gun 30. By adopting the transmission method of synchronous belt 42 and synchronous pulley 411, the problems of lifting jamming, shaking and iron filings contaminating raw materials caused by the traditional screw method are avoided. At the same time, the transmission method of synchronous belt 42 and synchronous pulley 411 has higher transmission accuracy and efficiency than the traditional flat belt or V belt, and less friction and wear, thereby improving the lifting efficiency and accuracy of the material gun lifting mechanism.

[0028] Optionally, the material selection for the synchronous pulley 411 should take into account wear resistance and strength. Common materials include steel, aluminum alloy, or engineering plastics to ensure long-term stability and reliability. The synchronous belt 42 can be made of polyurethane or polyvinyl chloride, which have good wear resistance and chemical corrosion resistance. As long as the synchronous belt 42 and the synchronous pulley 411 can be precisely matched and connected to achieve synchronous movement, it is acceptable.

[0029] like Figure 2 As shown, in this embodiment, the drive assembly 40 also includes a guide wheel 43, which is rotatably mounted on the drive member 41 to ensure free rotation on the drive member 41 and reduce friction with the synchronous belt 42. The synchronous belt 42 wraps around the outside of the guide wheel 43, thus forming a continuous and closed transmission path, ensuring that the synchronous belt 42 can run smoothly during driving without skipping teeth or derailment. When the drive motor starts, the synchronous wheel 411 connected to the output shaft of the drive motor drives the synchronous belt 42 to move by rotating. During the process of the synchronous belt 42 wrapping around the guide wheel 43, the rotation of the guide wheel 43 can keep the synchronous belt 42 on the preset path, avoiding lateral deviation of the synchronous belt 42 during operation and improving the stability and reliability of the transmission. The design of the guide wheel 43 ensures that the synchronous belt 42 will not deviate from the predetermined path during the driving process, thus avoiding transmission failure. On the other hand, it also plays a tensioning role, maintaining the appropriate tension of the synchronous belt 42 and preventing transmission failure caused by excessive looseness or tightness. At the same time, it ensures the stability of the synchronous belt 42 during the movement process, reduces the vibration and shaking of the synchronous belt 42 during the transmission process, and further improves the transmission accuracy and stability of the suction gun lifting mechanism.

[0030] Optionally, the guide wheel 43 can be a roller structure or a bearing structure. The outer diameter of the guide wheel 43 needs to match the width and thickness of the synchronous belt 42 to form a stable contact surface and effectively guide the movement of the synchronous belt 42. The guide wheel 43 can be made of a wear-resistant engineering material to ensure that the wheel surface of the guide wheel 43 wears less during long-term operation, thus extending its service life.

[0031] like Figure 2 As shown, in this embodiment, there are multiple guide wheels 43, and guide wheels 43 are provided on both sides of the synchronous pulley 411 along the length direction of the synchronous belt 42. This ensures that the synchronous belt 42 is in a taut state when it passes through multiple guide wheels 43 in the length direction, thus ensuring stable operation of the synchronous belt 42. When the synchronous belt 42 is long or the load is large, the number of guide wheels 43 can be appropriately increased to disperse the lateral force of the synchronous belt 42, reduce its deviation, and ensure that the guide wheels 43 can guide and tension the synchronous belt 42, ensuring that the synchronous belt 42 runs smoothly along the predetermined path under the drive of the drive motor. By providing guide wheels 43 on both sides of the synchronous pulley 411, on the one hand, the tension of the synchronous belt 42 can be effectively dispersed to avoid local excessive tension or slack, while limiting its lateral displacement to avoid deviation or skipping of the synchronous belt 42 during driving; on the other hand, multiple guide wheels 43 can also help adjust the movement path of the synchronous belt 42, ensuring that it can run smoothly in complex or confined spaces, improving the adaptability and flexibility of the mechanism. In this embodiment, there are two guide wheels 43, both located on the same side of the synchronous wheel 411 and symmetrically arranged relative to the synchronous wheel 411.

[0032] Optionally, the position and number of guide wheels 43 may be set according to actual needs to ensure that the lateral force of the timing belt 42 can be distributed and its offset reduced.

[0033] like Figure 2As shown, in this embodiment, the suction gun lifting mechanism further includes a guide assembly 50, which includes a slider 51 and a guide rail 52. Specifically, the slider 51 is the part of the guide assembly 50 connected to the sliding frame 20, and it directly contacts the guide rail 52. This ensures that friction and wear between the slider and the guide rail 52 are reduced during sliding, maintaining good sliding performance. The guide rail 52 is fixed to the fixed frame 10 and extends longitudinally, providing a sliding path and support, forming a relatively sliding guide mechanism. In this way, the slider 51 can slide up and down along the guide rail 52, ensuring that the suction gun 30 and the sliding frame 20 can perform smooth and precise vertical lifting movements under the drive of the drive assembly 40. Through the design of the guide assembly 50, not only is a stable guiding effect provided for the suction gun lifting mechanism, but also the motion accuracy and reliability are improved by reducing friction and shaking. This embodiment provides two sliders 51, which correspondingly contact and cooperate with the guide rail 52 at the two slider 51 positions. Of course, the positions of slider 51 and guide rail 52 can also be interchanged, that is, slider 51 is set on sliding frame 20, and guide rail 52 is set on fixed frame 10.

[0034] Optionally, multiple sliders 51 can be set on the sliding frame 20 to cooperate with multiple contact points of the guide rail 52 to improve the stability of the entire mechanism and reduce the offset during the movement. The guide rail 52 is made of materials such as high-strength steel or aluminum alloy to ensure that the guide rail 52 can provide stable support and guidance when the suction gun 30 is raised and lowered, reduce shaking, and improve positioning accuracy.

[0035] In this embodiment, the suction gun lifting mechanism also includes a bellows cover. Specifically, the bellows cover has good flexibility and can extend and retract with the lifting and lowering of the sliding frame 20, thus protecting related components. The two ends of the bellows cover are connected to the sliding frame 20 and the fixed frame 10, respectively. The bellows cover covers at least a portion of the drive assembly 40, including but not limited to key components such as the drive motor, synchronous pulley 411, guide pulley 43, and synchronous belt 42. Through a tightly fitting design, a closed protective space is formed. As the sliding frame 20 moves up and down, the bellows cover extends or folds accordingly, always covering the drive assembly 40 and ensuring it is fully protected in any position. The bellows cover not only provides effective protection for the suction gun lifting mechanism but also improves the cleanliness and safety of the entire raw material processing process by isolating the internal and external environments. It also provides additional safety for operators, preventing accidental contact with high-speed rotating components and reducing operational risks.

[0036] Optionally, the accordion cover is made of a wear-resistant and corrosion-resistant flexible material, such as polyurethane, PVC or special fabric, and can extend and retract with the lifting and lowering of the sliding frame 20 to ensure protection for the components housed inside.

[0037] like Figure 1 As shown, in this embodiment, the top of the sliding frame 20 has a first accordion cover mounting plate 60, the main function of which is to fix the top of the accordion cover, ensuring that the accordion cover can extend and retract with the lifting and lowering of the sliding frame 20. The fixing frame 10 has a second accordion cover mounting plate, which is located below the first accordion cover mounting plate 60, and is used to fix the bottom of the accordion cover, ensuring that the bottom of the accordion cover remains stable under any circumstances and will not loosen or fall off. The top and bottom of the accordion cover are connected to the first accordion cover mounting plate 60 and the second accordion cover mounting plate, respectively. This connection method ensures that both ends of the accordion cover are firmly fixed in the suction gun lifting mechanism, maintaining good stability even when the sliding frame 20 is lifted and lowered significantly and moves at high speed. In this way, when the sliding frame 20 rises or falls, the first bellows cover mounting plate 60 moves accordingly, while the second bellows cover mounting plate remains stationary. Under the traction of both ends, the bellows cover extends or compresses through its folding structure. This design not only ensures that the bellows cover can tightly cover the drive component 40, effectively isolating the external environment and preventing dust and other contaminants from entering, but also isolates substances such as iron filings generated by internal mechanical movement, preventing them from contaminating the raw materials, thereby maintaining the cleanliness of the raw materials and the quality of the products. In addition, the telescopic movement of the bellows cover can also provide additional safety protection, preventing operators from accidentally coming into contact with the high-speed moving drive component 40.

[0038] like Figure 2 As shown, in this embodiment, the sliding frame 20 includes a first segment 21 and a second segment 22 connected by sequential bending, forming an L-shaped structure. The first segment 21 extends laterally, primarily supporting the suction gun 30 through its mounting holes 23, enabling the suction gun 30 to move up and down. This lateral extension design allows the suction gun 30 to be more stable and flexible when handling materials horizontally, while also providing sufficient operating space. The second segment 22 extends longitudinally, mainly supporting the synchronous belt 42 that mounts the drive assembly 40. The upper and lower ends of the synchronous belt 42 are fixed to the upper and lower ends of the second segment 22, allowing the drive motor to move the sliding frame 20 up and down via the synchronous belt 42, thus controlling the lifting and lowering of the suction gun 30. The suction gun 30 and mounting hole 23 are designed to be rotatable. This means that the suction gun 30 can not only move vertically but also rotate within a certain range horizontally to adapt to different suction angles or avoid collisions with obstacles in the working environment, ensuring that the suction gun 30 maintains good balance and stability during lifting or rotation. The design of the sliding frame 20 improves the working efficiency of the drive assembly 40, reduces energy loss, and ensures the smoothness and accuracy of the suction gun 30's lifting and lowering. Furthermore, it saves space, allowing for a more rational layout of the drive assembly 40 and facilitating maintenance and adjustment.

[0039] like Figure 1 As shown, in this embodiment, the suction gun 30 includes a suction section 31, a connecting pipe 32, and a clamping member 33. The suction section 31 is the core component of the suction gun 30, which has a cavity and a suction head. The design of the cavity and suction head ensures good airtightness and structural stability, thereby forming a stable negative pressure during the suction process and effectively sucking up materials. One end of the connecting pipe 32 is connected to the suction section 31. Specifically, one end of the connecting pipe 32 is connected to the top of the suction section 31, and the other end is connected to other external equipment, ensuring smooth airflow and smooth material delivery, while reducing energy loss and material residence time in the pipe, and improving overall suction efficiency. The suction part 31 is inserted through the mounting hole 23. The clamping member 33 is located on the outer periphery of the suction part 31 and is connected to the sliding frame 20 to clamp the suction part 31 in the mounting hole 23. The design of the clamping member 33 ensures that the suction gun 30 does not loosen or shake during lifting or rotation, but it is not too tight to avoid damaging the suction part 31, thus ensuring the stability and safety of the suction gun 30 in complex working environments.

[0040] Optionally, the clamping component 33 can be made of elastic metal or engineering plastic, possessing a certain degree of deformation capability and self-locking function. The connection between the clamping component 33 and the sliding frame 20 can be achieved through bolts, clips, or other fasteners, ensuring the reliability and stability of the connection. The connection points between the suction part 31 and the connecting pipe 32, as well as with the sliding frame 20, must have good sealing performance to prevent airflow leakage and affect suction efficiency.

[0041] like Figure 3 As shown, this embodiment also provides a material suction device, including a suction frame and the aforementioned suction gun lifting mechanism. The suction frame has a suction chamber 70 for accommodating ton bags. The suction gun lifting mechanism is movably mounted above the suction frame. The suction gun 30 of the suction gun lifting mechanism can descend and extend into the suction chamber to suction material. Specifically, the suction gun 30, through the cooperation of the drive assembly 40 and the sliding frame 20, can achieve precise vertical lifting movement. When the material suction device is ready to perform a suction operation, the suction gun 30 descends with the sliding frame 20 until its suction part 31 extends into the ton bag in the suction chamber 70, forming a suction channel. At this time, the suction gun 30 begins to work, generating negative pressure through its cavity and suction head to efficiently suck up the material in the ton bag and transport it to a designated location. After suction is completed, the suction gun 30 rises to its initial position under the drive of the drive assembly 40, preparing for the next suction. The design of the above-mentioned suction device not only enables the lifting and lowering of the suction gun 30 and the suction process to be completed automatically by the control system, greatly reducing the need for manual operation and improving production efficiency, but also avoids contaminating the material with impurities such as iron filings and dust generated during the suction process, ensuring the cleanliness of the material handling process.

[0042] It should be noted that "multiple" in the above embodiments refers to at least two.

[0043] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0044] 1. The lifting control of the suction gun has been optimized, achieving precise positioning, smooth lifting and lowering, and efficient material suction.

[0045] 2. Compared with traditional cylinder or screw drives, belt drives have higher transmission efficiency, less friction and wear, and avoid the problem of iron filings contaminating raw materials.

[0046] 3. Compared with traditional flat belts or V-belts, the synchronous belt and synchronous pulley transmission method has higher transmission accuracy and efficiency, and less friction and wear, thereby improving the lifting efficiency and accuracy of the material gun lifting mechanism.

[0047] 4. It ensures that the synchronous belt will not deviate from the predetermined path during the driving process, thus avoiding transmission failure;

[0048] 5. The guide wheel has a tensioning function, maintaining the appropriate tension of the synchronous belt and preventing transmission failure caused by excessive looseness or tightness. At the same time, it ensures the stability of the synchronous belt during movement, reduces the vibration and shaking of the synchronous belt during transmission, and further improves the transmission accuracy and stability of the suction gun lifting mechanism.

[0049] 6. Effectively isolates the external environment, preventing dust and other pollutants from entering. It can also isolate iron filings and other substances generated by internal mechanical movement, preventing them from contaminating the raw materials, thereby maintaining the cleanliness of the raw materials and the quality of the products.

[0050] 7. The retractable movement of the bellows cover also provides additional safety protection, preventing operators from accidentally coming into contact with the high-speed moving drive components.
