Description

Technical Field

[0001] This utility model relates to the field of automated feeding equipment technology, specifically to a feeding device with dual discharge ports that can realize the step-by-step lifting and independent control of materials. Background Technology

[0002] In automated production lines, the demand for simultaneous material feeding at multiple workstations is increasing, and traditional single-outlet feeding devices have significant shortcomings: First, a single outlet cannot meet the parallel feeding needs of multiple production lines, resulting in low efficiency; second, in dual-outlet scenarios, traditional devices often use two independent systems spliced ​​together, leading to complex structures and large footprints; third, dual-outlet control lacks coordination, making it impossible to flexibly adjust the feeding rhythm according to the needs of different workstations, easily leading to material accumulation or feeding interruptions. Therefore, there is an urgent need for a compact, independently controllable lifting feeding device with dual outlets to achieve efficient and accurate multi-line feeding. Utility Model Content

[0003] This utility model provides a dual-discharge lifting feeding device, which achieves independent control of dual discharge ports and graded material conveying through the coordinated operation of parallel dual hoppers, dual lifting conveyor assemblies and dual belt conveyor units, solving the problems of complex structure and inflexible control of traditional dual-discharge devices.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A dual-discharge lifting feeding device includes a body, two hoppers arranged side by side on the body, two belt conveyor units positioned directly above the two hoppers, two lifting conveyor assemblies within the body corresponding to the two hoppers, and two blocking units positioned between each lifting conveyor assembly and the corresponding belt conveyor unit. The lifting working surface of each lifting conveyor assembly extends inclined toward the corresponding belt conveyor unit into the hopper, for conveying materials step by step to the belt conveyor unit. Each blocking unit is used to temporarily control the flow of materials into the corresponding belt conveyor unit.

[0006] Furthermore, each of the belt conveyor units includes a conveyor belt horizontally positioned directly above the corresponding hopper and a drive motor for driving the conveyor belt. The first section of the conveyor belt is located below the discharge port of the corresponding blocking unit, and the last section is equipped with a sensing component for sensing whether the material is in place.

[0007] Furthermore, each of the blocking units is provided with a pair of discharge guide plates at its discharge port position. The discharge guide plates form a guide slope to ensure that the material falls accurately into the corresponding conveyor belt.

[0008] Furthermore, each of the aforementioned lifting and conveying assemblies includes:

[0009] The stepped lifting unit is located on one side of the corresponding hopper inside the machine body, and its lifting working surface is inclined to the direction of the corresponding belt conveyor unit inside the hopper.

[0010] The power unit is located on the side of the machine body away from the hopper, and is used to drive the stepped lifting unit to lift and convey materials from bottom to top step by step.

[0011] Furthermore, each of the stepped lifting units includes side frames symmetrically arranged on the left and right axes within the machine body, and a plurality of fixed lifting blocks and lifting blocks arranged on the inclined side of the side frames; the fixed lifting blocks are vertically fixed on the inclined side of the side frames, and the lifting blocks are vertically slidably engaged with the side frames and located between adjacent fixed lifting blocks, driven up and down by corresponding power components, and cooperate with the fixed lifting blocks to form a stepped lifting surface.

[0012] Furthermore, the top surface of each of the fixed lifting blocks and the lifting blocks is an inclined surface, and the direction of inclination of the inclined surface is opposite to the direction of the side frame's inclined side; when the lifting block rises to be flush with the top surface of the adjacent fixed lifting block, the material slides down the inclined surface to the inclined surface of the fixed lifting block, thus achieving a stepped lifting.

[0013] Furthermore, each of the aforementioned power components includes:

[0014] The lifting frame abuts against the bottom of the corresponding lifting block and is vertically guided by the slider rail module and set inside the side frame;

[0015] The lifting component is fixedly connected to the lifting frame.

[0016] A power source drives the lifting component and the lifting frame to move up and down as a whole. The power source is one or a combination of a motor, a cylinder, a hydraulic cylinder, or an electric push rod.

[0017] Furthermore, when the power source is an electric motor, the motor output shaft is connected to a rotating wheel, and the circumferential side of the rotating wheel and the lower end of the push rod form a rotating pair through a pin. The upper end of the push rod is rotatably connected to the lifting component, thus forming a crank-connecting rod transmission structure.

[0018] Furthermore, each of the blocking units includes a baffle disposed between the tops of the corresponding side frames, and a cylinder that drives the baffle to move up and down to open or close the discharge port.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention features a parallel arrangement of dual material bins, a dual-lifting conveyor assembly, and a dual-belt conveyor unit, enabling independent material supply from two outlets. This meets the needs of multi-station synchronous production and enhances production line flexibility. The tiered lifting unit, through the cooperation of fixed lifting blocks and lifting blocks, forms a stepped lifting surface, allowing materials to rise gradually, preventing accumulation and blockage, and ensuring stable conveying. The blocking unit, driven by a cylinder, opens and closes the outlet via a baffle. Combined with the sensing component at the tail end of the belt conveyor unit, it can adjust the feeding frequency in real time according to the production rhythm, preventing material accumulation or shortage. This invention integrates the dual-outlet system into a single unit, reducing the floor space by approximately 50% compared to two separate devices. Furthermore, the power components can share a drive structure, reducing costs. Attached Figure Description

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] As shown in Figure 1-2, the dual-discharge lifting feeding device mainly consists of a machine body 1, two parallel hoppers 2, two belt conveyor units 5, two lifting conveyor assemblies 3, and two blocking units 4. The hopper 2 has an inverted conical structure and is fixedly installed on the top of the machine body 1, facilitating the material to slide down to the lifting working surface of the lifting conveyor assembly 3. The two belt conveyor units 5 are horizontally placed directly above the corresponding hoppers 2, with the first section of the conveyor belt 52 located below the discharge port of the corresponding blocking unit 4, and the sensing component at the end of the belt can detect whether the material has been conveyed to the correct position.

[0031] As shown in Figure 3-5, the stepped lifting unit 30 of the lifting and conveying assembly 3 is fixed to the machine body by symmetrical side frames 31. The inclined sides of the side frames 31 are arranged along the inner wall of the hopper 2. The fixed lifting blocks 33 are vertically fixed to the inclined sides of the side frames 31, and the lifting blocks 32 that can slide up and down are arranged between adjacent fixed lifting blocks 33. The lifting frame 34 of the power assembly 35 abuts against the bottom of all the lifting blocks 32. When the power source (such as the motor 35) drives the rotating wheel 36 to rotate, the lifting frame 34 is driven to move up and down along the slider rail module inside the side frame 31 through the crank connecting rod structure (rotating wheel 36 - push rod 37 - lifting component 38), driving the lifting blocks 32 to rise and fall synchronously.

[0032] Both the fixed lifting block 33 and the lifting block 32 have inclined surfaces on their top surfaces, and the direction of inclination of the inclined surfaces is opposite to that of the inclined side of the side frame 31. When the lifting block 32 rises to be flush with the top surface of the adjacent fixed lifting block 33, the inclined surfaces of the two form a continuous stepped lifting surface. The material slides down from the bottom of the hopper 2 along the inclined surface step by step until it is conveyed to the blocking unit 4.

[0033] As shown in Figure 3, the cylinder 41 of the blocking unit 4 is fixed to the top of the side frame 31. The cylinder piston rod is connected to the baffle 42. The cylinder 41 extends and retracts to drive the baffle 42 to rise and fall, thereby opening and closing the discharge port. The discharge guide plates 6 on both sides of the discharge port form a guide slope. When the baffle 42 rises to open the discharge port, the material slides down the guide slope to the conveyor belt 52 under the push of the lifting conveyor assembly 3. When the baffle 42 falls to close the discharge port, the material is blocked in the hopper, realizing independent control of the two discharge ports.

[0034] The conveyor belt 52 of the belt conveyor unit 5 is driven by the drive motor 51. When the sensing component detects that the material at the end of the conveyor belt has arrived, the control system sends a signal to the corresponding blocking unit 4. The cylinder 41 drives the baffle 42 to descend and close the discharge port, pausing the material conveying. When the material at the end is removed, the sensing component sends a feedback signal, the baffle 42 rises and opens the discharge port, and the lifting conveyor assembly 3 continues to lift the material onto the conveyor belt, forming a two-line independent automated cycle feeding process. It is worth mentioning that the material that is not successfully removed can fall directly into the hopper through the end of the conveyor belt.

[0035] It is worth mentioning that the sensing component is a through-beam fiber optic detection element. In addition to setting the sensing component, a visual detection device can also be set directly above the tail section of the conveyor belt to detect whether the material is in place, thereby controlling the stop or operation state of the conveyor belt. Any relevant detection mechanism used to detect the material in place is within the protection scope of this utility model.

[0036] The power source of the power assembly 35 can be selected according to production needs: when precise control of lifting displacement is required, an electric push rod or servo motor is selected; when rapid response is required, a cylinder or hydraulic cylinder is selected. Taking the motor 35 drive as an example, the rotation of the motor 35 drives the rotating wheel 36 to perform circular motion. The rotating wheel 36 is hinged to the lower end of the push rod 37 through a pin shaft, and the upper end of the push rod 37 is hinged to the lifting component 38, forming a crank-connecting rod mechanism. This mechanism converts the rotational motion of the motor into the vertical reciprocating motion of the lifting component 38 and the lifting frame 34, ensuring the smooth operation of the lifting block 32 and realizing the synchronous or independent drive of the two lifting and conveying assemblies.

[0037] This invention effectively solves the efficiency and control problems of traditional multi-line feeding devices through the synergy of dual-discharge structure design, stepped lifting, and precise blocking control. It can be widely applied to automated production line scenarios that require simultaneous feeding at two workstations.
