Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to an intermittent lifting conveying and automatic unloading mechanism. Background Technology

[0002] In production lines where materials need to be cleaned, soaked, sterilized, or surface-treated, materials typically need to move between different stations. For example, they may be sent from a receiving station to a treatment tank, and after treatment, they may be removed and dumped to the next process. The core requirement of this process is that the material handling equipment must have reliable vertical lifting and conveying capabilities to ensure that the material can be immersed in the treatment medium, such as a cleaning solution, and that the material can be automatically and thoroughly dumped and unloaded after the process is completed.

[0003] To prevent materials from slipping from the support device due to vibration, impact, or media flow during lifting or processing, side baffles or clamping mechanisms are typically added. However, these anti-fall structures directly obstruct the material's path at the unloading station, necessitating an additional drive unit to open or retract these baffles before unloading. Conversely, if a tilting hopper design is used to simplify unloading, a separate power source, such as a cylinder or motor, is required for the hopper's tilting action. This makes the entire mechanism complex and expensive, and in typical humid and moisture-laden conditions, these additional electrical or pneumatic components become frequent points of failure, severely impacting the equipment's reliability and applicability.

[0004] Therefore, existing technologies are often forced to compromise between structural simplification, operational reliability, and functional completeness, resulting in equipment that is either insufficient in preventing falls and causing material loss, or has a complex structure, many failure points, and is difficult to adapt to harsh working conditions. Application content

[0005] In view of this, this application proposes an intermittent lifting conveying and automatic unloading mechanism, which aims to solve the problems that existing lifting conveying and unloading mechanisms are difficult to balance preventing falling during the conveying process and automatic tilting and unloading at the end point, and have complex structures and poor adaptability to working conditions.

[0006] The technical solution of this application is implemented as follows: This application provides an intermittent lifting conveying and automatic unloading mechanism, including: frame; The load-bearing component is used to receive and transport materials, and its top and front sides are open. A front-end connection assembly is used to form a rotatable connection between the front end of the carrier and the frame, and to allow vertical movement along the frame. The rear connection assembly includes a first rotating shaft and a guide member. The guide member is fixedly connected to the rear end of the carrier member. A sliding groove is provided on the guide member. The first rotating shaft passes through the sliding groove and forms a sliding pair and a rotatable connection with the guide member. The first rotating shaft and the frame form a slidable connection in the vertical direction. The front upper limit and the front lower limit are both fixed on the frame, and the front upper limit and the front lower limit correspond to the upper limit position and the lower limit position of the front end of the bearing member, respectively. A lifting drive assembly is mounted on the frame. The drive end of the lifting drive assembly is connected to the carrier component. The drive end of the lifting drive assembly is located between the front rotation center of the carrier component and the first rotating shaft, and is close to the front rotation center of the carrier component. The carrier is configured such that when it descends and its front end is blocked by the lower front limiter, it forms an inclined posture with the front end high and the rear end low; when it ascends to the unloading station and its front end is blocked by the upper front limiter, it flips forward around its front rotation center, and the first rotating shaft adapts to the change in center distance during the flipping process by sliding along the chute.

[0007] Based on the above technical solution, preferably, it also includes a discharge flap, the lower edge of which is rotatably connected to the lower edge of the front opening of the carrier through a hinge; the hinge allows the discharge flap to have a degree of freedom to rotate relative to the carrier in the range of 0° to 90°, when rotated to 0°.

[0008] Based on the above technical solution, preferably, a stop is provided on the frame corresponding to the front side of the carrier; when the carrier moves down to the position where its front end abuts against the front lower limit member, the unloading flap flips to a closed state under the obstruction of the stop to block the front opening of the carrier.

[0009] Based on the above technical solution, preferably, the lifting drive assembly includes a drive unit, a drum driven by the drive unit, and a transmission traction member; one end of the transmission traction member is wound around the drum, and the other end is connected to the carrier member.

[0010] Based on the above technical solution, preferably, the transmission traction component is any one of wire rope, chain or synchronous belt.

[0011] Based on the above technical solution, preferably, the front-end connection assembly includes a second rotating shaft rotatably connected to the front end of the carrier, and a sliding member that slidably connects both ends of the second rotating shaft to the frame in a vertical direction.

[0012] Based on the above technical solution, preferably, the frame is further fixedly provided with a rear upper limit member and a rear lower limit member. The rear upper limit member and the rear lower limit member correspond to the upper limit position and the lower limit position of the rear end of the bearing member, respectively. The rear upper limit member is located above the front upper limit member, and the rear lower limit member is located below the front lower limit member.

[0013] Based on the above technical solution, preferably, the angle of inclination formed by the gradual raising of the bearing bottom surface of the bearing member from its rear end to its front end is 3° to 15°.

[0014] Based on the above technical solution, preferably, the bearing bottom surface of the bearing member is hollow.

[0015] Based on the above technical solution, preferably, a cleaning container with an upward opening is also fixedly installed on the frame, and the position of the cleaning container corresponds to the lifting path of the carrier, so that the carrier can descend and be immersed in the cleaning container.

[0016] This application has the following advantages over the prior art: 1) The intermittent lifting conveying and automatic unloading mechanism disclosed in this application, through the coordinated operation of the carrier component, the front and rear connecting components, a set of mechanical limiting components and a single lifting drive component, sequentially completes the two core actions of forming an inclined anti-fall posture and automatically flipping and unloading in place with only a single lifting drive source. This fundamentally solves the technical contradiction of the difficulty in simultaneously achieving anti-fall and smooth unloading. The overall structure is thus greatly simplified, eliminating the need for an independent flipping drive and a complex control unit, and significantly improving the operational reliability and durability under harsh working conditions such as humidity and dust.

[0017] 2) By introducing a fixed stop on the frame, the closing action of the unloading flap is transformed into a purely mechanical and inevitable linkage triggered by the downward movement of the entire carrier component. This design achieves automatic and reliable closing of the unloading flap at the processing station without the need for any additional sensors, cylinders, or motors, further simplifying the structure and control. Simultaneously, the closed flap and the carrier component together form a front-constrained cavity, effectively preventing material from slipping from the front during subsequent lifting, vibration, or liquid impact, significantly improving the mechanism's anti-fall reliability under harsh operating conditions.

[0018] 3) By setting a rear upper limit stop and a rear lower limit stop, with the rear upper limit stop positioned vertically above the front upper limit stop and the rear lower limit stop positioned below the front lower limit stop, this staggered height design ensures that the rear end of the carrier component has a larger lifting stroke space than the front end. This allows the rear end of the carrier component to descend fully to form the required front-high, rear-low tilt posture; at the same time, it also ensures that at the unloading station, the rear end can rise fully to provide a sufficient tilting angle, thereby smoothly and thoroughly completing the unloading action.

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1 As shown, combined with Figure 2-6 This application discloses an intermittent lifting conveying and automatic unloading mechanism, including a frame 1, a bearing 2, a front connecting component 3, a rear connecting component 4, a front upper limit component X1, a front lower limit component X2, and a lifting drive component 5.

[0023] The frame 1 forms the installation foundation and support skeleton of the entire mechanism, providing fixed installation positions and stable running tracks for all other functional components, ensuring the overall rigidity and stability of the mechanism during operation.

[0024] The carrier 2 is used to directly receive the material W to be processed. Its top is designed to be open to facilitate receiving the material from above. Its front side is also designed to be open. This structure allows the material W to be smoothly discharged from the opening without any obstruction when the carrier 2 is flipped forward, thus realizing the natural formation of the discharge port.

[0025] The front-end connecting component 3 is used to connect the front end of the carrier 2 to the frame 1. Specifically, the front-end connecting component 3 can rotate relative to the frame 1 and slide up and down along the vertical direction of the frame 1. This composite motion freedom provides the basis for subsequent automatic posture transformation and flipping unloading.

[0026] The rear-end connection component 4 is crucial for the mechanism to achieve adaptive motion. Specifically, the rear-end connection component 4 includes a first rotating shaft 41 and a guide member 42. The guide member 42 is fixedly connected to the rear end of the bearing member 2, forming a rigid whole. A linear groove 421 is provided on the guide member 42, through which the first rotating shaft 41 passes. Therefore, two independent motion relationships are formed between the first rotating shaft 41 and the guide member 42: first, the first rotating shaft 41 can slide freely along the extension direction of the groove 421; second, the first rotating shaft 41 can rotate within the groove 421. At the same time, both ends of the first rotating shaft 41 are constrained on the vertical guide rails of the frame 1, and can only move up and down in the vertical direction.

[0027] The front upper limit stop X1 and the front lower limit stop X2 are fixedly installed at a specific height position on the frame 1. The front lower limit stop X2 precisely corresponds to the lowest permissible position for the downward movement of the front end of the carrier 2, i.e., the downward limit position. The front upper limit stop X1 precisely corresponds to the highest permissible position for the upward movement of the front end of the carrier 2, i.e., the upward limit position. They rigidly constrain the stroke of the front end of the carrier 2 through mechanical contact.

[0028] The lifting drive assembly 5 is the sole power source for the mechanism, and its drive end is connected to the carrier 2 via a transmission. The point of application of this drive end is set on the line connecting the front rotation center of the carrier 2 and the rear first rotating shaft 41, and is positioned closer to the front rotation center. This eccentric setting results in a larger torque generated by the driving force on the rear end, making it easier for the rear end of the carrier 2 to sink under the combined effect of gravity.

[0029] The entire mechanism’s workflow and effects are achieved by two preset states of the carrier component 2.

[0030] When the lifting drive assembly 5 drives the carrier 2 downward, and the front end of the carrier 2 contacts the lower front limit piece X2 and stops descending, the lifting drive assembly 5 continues to release traction. The rear end of the carrier 2 continues to descend under its own weight and traction, forcing the carrier 2 to begin tilting backward around the front rotation center. At this time, the guide piece 42 fixed to the rear end deflects counterclockwise. To adapt to this change in the angle of the guide piece 42, the first rotating shaft 41 slides relative to the guide piece 421, moving along the guide piece 421 towards the rear end of the carrier 2 (i.e., away from the front rotation center). This sliding allows the position of the first rotating shaft 41 in the vertical guide rail of the frame 1 to coordinate with the new angle of the guide piece 42, thus smoothly establishing the tilting posture.

[0031] As a result, the support component 2 forms a stable inclined posture with a higher front end and a lower rear end. At this time, the center of gravity of the material W on the inclined bottom surface naturally shifts to the rear, effectively overcoming the vibration and impact during lifting or processing, and fundamentally preventing the material W from slipping off from the front.

[0032] When the process is completed, the lifting drive assembly 5 drives the carrier 2 to the unloading station, where its front end contacts and is blocked by the front upper limit member X1. The lifting drive assembly 5 continues to pull the rear end of the carrier 2 upward, forcing it to flip forward with the front end as the axis. As the flipping angle increases, the straight-line distance between the front rotation center of the carrier 2 and the rear first rotating shaft 41 will indeed gradually shorten. To automatically compensate for this shortened center distance, the first rotating shaft 41 will slide in the reverse direction in the groove 421 of the guide member 42 while continuing to rise, that is, move towards the front end of the carrier 2 (i.e., towards the rotation center). This sliding process eliminates the structural interference caused by the shortened distance, ensuring that the flipping action is smooth and without jamming. The material W is then poured out from the front opening along the inclined carrier bottom surface under the action of gravity, completing the automatic unloading.

[0033] The intermittent lifting conveying and automatic unloading mechanism disclosed in this application, through the coordinated operation of the carrier component 2, the front and rear connecting components, a set of mechanical limiting components, and a single lifting drive component 5, sequentially completes the two core actions of forming an inclined anti-fall posture and automatically flipping and unloading in place using only a single lifting drive source. This fundamentally solves the technical contradiction of the difficulty in simultaneously achieving anti-fall and smooth unloading. The overall structure is thus greatly simplified, eliminating the need for a separate flipping drive and a complex control unit, and significantly improving the operational reliability and durability under harsh working conditions such as humidity and dust.

[0034] To further optimize the stability of the material receiving and conveying process and enhance the anti-falling effect during lifting and processing, the embodiments of this application also provide the following solutions.

[0035] Specifically, this application embodiment also provides a discharge flap 6, the lower edge of which is rotatably connected to the lower edge of the front opening of the bearing member 2 via a hinge member G.

[0036] The hinge G is designed to allow the unloading flap 6 to freely rotate relative to the carrier 2 within an angle range of 0 to 90 degrees. When the rotation angle is 0 degrees, the unloading flap 6 is in a specific reference position, at which point its surface is perfectly aligned with the edge of the front opening of the carrier 2, in a coplanar or smoothly connected state. This facilitates the smooth introduction of material W into the carrier 2 by the front-end process using the unloading flap 6. Furthermore, during unloading, material W can be smoothly guided from the carrier 2 along the unloading flap 6 to the rear-end process.

[0037] When the flip angle is 90°, the side openings of the unloading flap 6 and the carrier 2 are closed, further preventing the material W from moving up and down in the carrier 2 or from coming out of the side openings of the carrier 2 during the cleaning process.

[0038] It should be noted that the 90° flip angle occurs during the downward movement of the carrier 2, that is, the front end of the carrier 2 tilts upward and the rear end tilts downward. As a result, the material W can be prevented from falling at the rear end of the bottom surface of the tilted carrier 2. The leakage flap can further prevent the material W from falling.

[0039] In order to enable the unloading flap 6 to close automatically and reliably during the downward movement, the following technical solution is also adopted in this embodiment.

[0040] Specifically, a stop 11 is provided on the frame 1 corresponding to the front side of the carrier 2; when the carrier 2 descends to the position where its front end abuts against the front lower limit member X2, the unloading flap 6 flips to a closed state under the obstruction of the stop 11 to block the front opening of the carrier 2.

[0041] The working process of the stop 11 is as follows: Under the drive of the lifting drive assembly 5, the carrier 2 begins to descend from the receiving station. During the descent, the unloading flap 6, hinged to the front of the carrier 2, first contacts the stationary stop 11. Due to the mechanical obstruction of the stop 11, the unloading flap 6 cannot continue to descend along the same path as the carrier 2, and is thus forced to begin rotating upward relative to the carrier 2 around its hinge axis, i.e., performing a closing action. Subsequently, the front end of the carrier 2 continues to descend a certain distance until it contacts the front lower limit member X2 on the frame 1 and is finally limited. At this moment, the unloading flap 6, guided by the stop 11, also completely flips to the closed state, tightly blocking the front opening of the carrier 2.

[0042] By introducing a fixed stop 11 on the frame 1, the closing action of the unloading flap 6 is transformed into a purely mechanical and inevitable linkage triggered by the downward movement of the entire carrier 2. This design achieves automatic and reliable closing of the unloading flap 6 at the process handling station without the need for any additional sensors, cylinders, or motors, further simplifying the structure and control. Simultaneously, the closed flap and the carrier 2 together form a front-constrained cavity, which effectively prevents material W from slipping from the front during subsequent lifting, vibration, or liquid impact, significantly improving the mechanism's anti-fall reliability under harsh operating conditions.

[0043] In order to achieve reliable and controllable lifting drive for the carrier 2, this application shows a structural configuration of the lifting drive assembly 5. Specifically, the lifting drive assembly 5 includes a drive unit 51, a drum 52, and a transmission traction member 53.

[0044] The drive unit 51 is the power source of the mechanism, and it is configured as a rotary output device such as a geared motor or a hydraulic motor. The drum 52 is connected to the output shaft of the drive unit 51 and is directly driven by the drive unit 51 to rotate in both directions. The transmission traction member 53 is a flexible force transmission medium, one end of which is wound around the outer circumference of the drum 52 in a specific manner, and the other end is connected to the support member 2.

[0045] In this embodiment, the free end of the transmission traction member 53 is fixedly connected to the top opening of the support member 2 through the door-shaped frame. In this way, the material W can smoothly enter the interior of the support member 2 through the front opening of the support member 2, and slide to the rear end of the inner bottom surface of the support member 2 during the downward tilting process, thereby preventing it from falling.

[0046] The working principle of the lifting drive assembly 5 is as follows: When it is necessary to lift the carrier 2, the drive unit 51 starts and drives the drum 52 to rotate in the winding direction. The rotation of the drum 52 gradually shortens the transmission traction member 53 wound on it, thereby applying an upward pulling force to the carrier 2 through the traction member, driving the carrier 2 to rise along its guide path. Conversely, when it is necessary to lower the carrier 2, the drive unit 51 drives the drum 52 to rotate in the unwinding direction, releasing a certain length of the transmission traction member 53, and the carrier 2 descends smoothly under its own weight. By controlling the direction and speed of the drive unit 51, the lifting stroke, speed, and stopping position of the carrier 2 can be precisely controlled.

[0047] In some embodiments, the transmission traction component 53 can be any one of a wire rope, a chain, or a synchronous belt. Preferably, the transmission traction component 53 in this embodiment is a wire rope, which has high strength, flexibility, and a certain degree of corrosion resistance, and is suitable for heavy-load or lifting scenarios where rigidity requirements are not high.

[0048] In some embodiments, the front-end connection assembly 3 includes a second rotating shaft 31 rotatably connected to the front end of the carrier 2, and a sliding member 32 that slidably connects both ends of the second rotating shaft 31 to the frame 1 in a vertical direction.

[0049] The second rotating shaft 31 is a horizontally positioned shaft that is rotatably connected to the front end of the support member 2, allowing the support member 2 to rotate around the axis of the second rotating shaft 31. Sliding members 32 are key components for vertical movement; at least two are installed at both ends of the second rotating shaft 31. These sliding members 32 are mounted on corresponding vertical guide rails on the frame 1, thus forming a vertically slidable connection between the two ends of the second rotating shaft 31 and the frame 1. In some embodiments, the sliding members 32 are configured as rollers, and the sidewalls of the frame 1 are provided with vertical guide rails, ensuring smooth vertical movement of the support member 2 without jamming.

[0050] It should be noted that both ends of the first rotating shaft 41 are also slidably connected to the frame 1 via the sliding member 32, so that the rear end of the bearing member 2 can slide smoothly along the frame 1 in the vertical direction.

[0051] In some embodiments, a rear upper limit stop X3 and a rear lower limit stop X4 are also fixedly provided on the frame 1. The rear lower limit stop X4 corresponds to the downward limit position of the rear end of the carrier 2 in the vertical direction, and is used to prevent the rear end of the carrier 2 from continuing to descend; the rear upper limit stop X3 corresponds to the upward limit position of the rear end of the carrier 2, and is used to prevent the rear end from continuing to rise.

[0052] The rear upper limit stop X3 is vertically positioned above the front upper limit stop X1, while the rear lower limit stop X4 is positioned below the front lower limit stop X2. This staggered height design is not arbitrary; it ensures that the rear end of the carrier 2 has a larger lifting range than the front end. This design allows the rear end of the carrier 2 to descend fully to achieve the required front-high, rear-low tilt posture; simultaneously, it ensures that at the unloading station, the rear end can rise fully to provide a sufficient tilting angle, thereby smoothly and thoroughly completing the unloading operation.

[0053] In some embodiments, the angle of inclination formed by the gradual raising of the bearing bottom surface of the bearing member 2 from its rear end to its front end is 3° to 15°.

[0054] If the angle is too small, meaning the bearing surface of the carrier 2 is too flat, during the lifting and lowering movement of the carrier 2 or in processes involving vibration and media disturbance such as ultrasonic cleaning or spray impact, the inertial force acting on the material W, causing it to slide forward, may be greater than the frictional force and gravitational component provided by the inclined surface to prevent sliding. This will result in an insignificant or unstable rearward shift of the material W's center of gravity, making it unable to reliably overcome external disturbances, and the material W will still be at risk of sliding forward. Simultaneously, it will also prevent the unloading flap 6 from effectively closing the side opening of the carrier 2.

[0055] If the angle is too large, the steep slope will cause the material W to accumulate excessively at the rear end within the support 2, affecting the uniformity of the material W's unfolding and wetting during the cleaning or soaking process, resulting in poor treatment effect. On the other hand, for long, cylindrical, or smooth-surfaced materials W, an excessively large angle will increase the risk of them suddenly accelerating backward and sliding against the tank wall due to their own weight, which may cause damage to the material W.

[0056] By setting the angle from 3 to 15 degrees, this embodiment ensures that the center of gravity of the material W is reliably and stably biased toward the rear end of the carrier 2 during the conveying and processing process, thereby fundamentally realizing and guaranteeing the effectiveness of the anti-falling function.

[0057] In some embodiments, the bearing bottom surface of the bearing member 2 is hollow. The hollow shape is composed of regular holes, slits, or components such as gratings and grids, so that the bottom surface presents a structural form with through gaps.

[0058] With its perforated design, when the carrier 2 carries the material W and descends to be immersed in the cleaning liquid, soaking liquid or other treatment medium to complete the process, the liquid can be quickly removed from the carrier 2 during the lifting and removal process. This significantly reduces the amount of liquid carried by the material W, allowing the material W to leave the liquid environment more quickly and prepare for subsequent unloading or entry into the next drying process.

[0059] In order to directly integrate the conveying and unloading mechanism with the working container required for wet processing, thereby forming a dedicated processing equipment with complete functions and compact structure, the embodiment of this application also fixes an upward-opening cleaning container on the frame 1. The position of the cleaning container corresponds to the lifting path of the carrier 2, so that the carrier 2 can descend and be immersed in the cleaning container.

[0060] When the lifting drive assembly 5 drives the carrier 2 to descend along its preset vertical trajectory, the carrier 2 can be accurately and smoothly immersed in the liquid inside the cleaning container; after the processing is completed, the carrier 2 can be completely lifted back above the container.

[0061] This embodiment of the application transforms the aforementioned conveying mechanism, which features anti-fall, automatic unloading, and efficient drainage functions, into an integrated device specifically designed for wet processes such as cleaning and soaking by adding a fixed cleaning container whose position precisely corresponds to the lifting path. This solution retains all the automation advantages of the original mechanism and further resolves the engineering application issues related to interfacing with external processing containers, enabling the device to be used in specific processes and significantly improving its practicality and market relevance in fields such as agricultural product cleaning, food processing, and parts surface treatment.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
