Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding equipment, in particular to a screw automatic feeding equipment. Background Art

[0002] Automated loading equipment is a highly automated material conveying and loading device widely used in a variety of industries, including food, chemicals, pharmaceuticals, metallurgy, and building materials. This type of equipment utilizes mechanical, electrical, sensor, and control technologies to automatically load, convey, meter, and package materials, significantly improving production efficiency and quality while reducing labor costs and intensity.

[0003] Automated feeding equipment typically includes the following types: Screw feeders, which push materials from a low level to a high level through rotating spiral blades, are suitable for conveying powdered and granular materials. Vibratory feeders, which utilize the excitation force generated by a vibrating motor to cause materials to jump and advance in a certain direction within the hopper, achieving automatic feeding. Belt conveyors, driven by a motor, continuously operate the conveyor belt, allowing materials to move along with the belt to achieve the desired conveying effect. Screw feeders, which use a screw as the driving force to smoothly convey the actuator arm or material, offer greater stability and superior driving force compared to other types of feeding mechanisms.

[0004] Based on this, Chinese patent CN217866877U discloses a screw feeding device, which includes two supporting vertical rods arranged in front and behind and a supporting platform fixed on the top of the supporting vertical rods, a screw is installed on the supporting platform, a transmission sprocket is provided on one side of the screw to drive its rotation, a transmission motor is provided on the bottom side of the transmission sprocket to drive its rotation, a vacuum clamp for clamping the product is provided on the top of the screw, and a cylinder is provided on the top of the vacuum clamp for driving the vacuum clamp to move up and down. The screw feeding device disclosed in this patent replaces the original structure using direct vibration with the use of screws to feed materials in sequence, changing the state of the direct vibration front end that is always vibrating, making the product more stable. Moreover, because of the use of screw feeding, the two products will not touch each other, thereby preventing the products from stacking together to form a jam, ensuring stable and smooth product feeding.

[0005] However, the screw feeding device disclosed above still has the technical problem of insufficient loading convenience. Specifically, the screw feeding device disclosed above mainly comprises a vacuum clamp for clamping products at the top of the screw, a cylinder for driving the vacuum clamp to move up and down is provided at the top of the vacuum clamp, and a movable module for driving the vacuum clamp to move left and right is provided at the rear side of the cylinder; thus, the vacuum clamp realizes the function of clamping the material. However, in actual production applications, most materials are difficult to be stably clamped by the vacuum clamp, such as materials with curved sides, rods, blocks, etc. Moreover, the application cost of the vacuum clamp is relatively high, and it is not convenient for subsequent maintenance; this affects the convenience of using the screw feeding device.

[0028] Please also refer to Figures 1 to 4 The utility model is a screw automatic feeding device comprising: a frame 1, a screw driving mechanism 2, a screw transmission mechanism 3, a first rotary driving mechanism 4 and a feeding actuator 5; the screw driving mechanism 2 is arranged in the frame 1, the screw transmission mechanism 3 is movably arranged on the frame 1, and the screw driving mechanism 2 is drivingly connected to the screw transmission mechanism 3; the first rotary driving mechanism 4 is arranged on the side of the frame 1, and the screw transmission mechanism 3 is drivingly connected to the first rotary driving mechanism 4; the feeding actuator 5 is arranged on the side of the screw transmission mechanism 3, and the first rotary driving mechanism 4 is drivingly connected to the feeding actuator 5.

[0029] Specifically, when the screw automatic feeding device of the present invention is in the working process, the screw drive mechanism 2 is first started and drives the screw transmission mechanism 3 to move, so that the screw transmission mechanism 3 raises or lowers the first rotary drive mechanism 4 to a preset position; then, the first rotary drive mechanism 4 is started to drive the feeding actuator 5 to swing to a preset angle, so that the feeding actuator 5 can be aligned with the material to be loaded. Next, the feeding actuator 5 is started and clamps the material to be clamped, and then the first rotary drive mechanism 4 drives the feeding actuator 5 to swing to another preset angle; thereafter, the screw transmission mechanism 3, driven by the screw drive mechanism 2, drives the first rotary drive mechanism 4 and the feeding actuator 5 to another preset position again, and the feeding actuator 5 releases the material to the preset position. Thereafter, each action component is reset. It can be seen that the utility model proposes a method of using a screw lifting mechanism to drive a rotating action mechanism, so that the rotating action mechanism can swing the feeding mechanism, thereby facilitating the feeding mechanism to clamp or release the material; this screw action mechanism has the advantages of simple structure, easy use and maintenance.

[0030] Furthermore, the screw drive mechanism 2 has a screw drive motor 201 and a coupling 202 ; the screw drive motor 201 is arranged on the frame 1 , the screw drive motor 201 is drivingly connected to the coupling 202 , and the coupling 202 is drivingly connected to the screw transmission mechanism 3 .

[0031] Furthermore, the screw transmission mechanism 3 has a screw 301, a screw bearing 302, a nut transmission sleeve 303 and an action support arm 304; the two ends of the screw 301 are respectively connected to a screw bearing 302, each of the screw bearings 302 is connected to the frame 1, and one end of the screw 301 is connected to the coupling 202; the nut transmission sleeve 303 is matched and connected to the screw 301, and the action support arm 304 is connected to the nut transmission sleeve 303; the first rotation drive mechanism 4 is arranged on the action support arm 304.

[0032] Specifically, after the screw drive motor 201 is powered on, it can drive the coupling 202 to drive the screw 301 to rotate forward or reverse. Both ends of the screw 301 are connected to the frame 1 through the screw bearing 302, thereby allowing the screw 301 to rotate within the frame 1. The nut drive sleeve 303 is movably connected to the screw 301, and the two can be connected by a thread. Therefore, when the screw 301 rotates forward or reverse, the nut drive sleeve 303 can be raised or lowered along the screw 301, and the nut drive sleeve 303 can then drive the action support arm 304 and the first rotation drive mechanism 4 to rise or fall.

[0033] Furthermore, the first rotary drive mechanism 4 is provided with a first rotary drive motor 401, a first rotary shaft 402, a first rotary bearing structure 403 and a swing connecting frame 404; the first rotary drive motor 401 is arranged on the action support arm 304, the first rotary drive motor 401 is drive-connected to the first rotary shaft 402, the first rotary bearing structure 403 is adjacent to the first rotary drive motor 401 and is arranged on the action support arm 304, the first rotary shaft 402 is movably connected to the first rotary bearing structure 403, the swing connecting frame 404 is arranged at one end of the first rotary shaft 402, and the feeding actuator 5 is arranged on the swing connecting frame 404.

[0034] Specifically, after the first rotary drive motor 401 is powered on, it can drive the first rotary shaft 402 to rotate, and then the swing connecting frame 404 arranged at the end of the first rotary shaft 402 can be driven to rotate, so that the loading actuator 5 arranged on the swing connecting frame 404 can swing to a preset angle as needed.

[0035] Furthermore, the feeding actuator 5 has a clamping drive cylinder 501, a clamping telescopic rod 502, a clamping link 503, a clamping claw 504 and a clamping claw link 505; the clamping drive cylinder 501 is connected to the swing connecting frame 404, and the clamping drive cylinder 501 is driven and connected to the clamping telescopic rod 502; one end of the clamping link 503 is connected to the clamping telescopic rod 502, and the other end of the clamping link 503 is connected to the clamping claw 504, the clamping claw 504 is movably connected to the clamping claw link 505, and the clamping claw link 505 is connected to the swing connecting frame 404.

[0036] Specifically, when the clamping drive cylinder 501 is activated, it can drive the clamping telescopic rod 502 to extend or retract, thereby driving the clamping jaw 504 to close or open via the clamping link 503. More specifically, when the clamping telescopic rod 502 extends, it pushes against the clamping link 503, causing it to push the clamping jaw 504 open around its connection with the clamping jaw link 505. When the clamping telescopic rod 502 retracts, it pulls on the clamping link 503, driving the clamping jaw 503 to close and clamp. This demonstrates that this clamping structure is simple, easy to implement, and maintain, and can improve the usability of the screw feeding mechanism.

[0038] Specifically, after the second rotary drive motor 602 is powered on and started, it can drive the rotary transmission structure 603 to move, and then the rotary transmission structure 603 drives the frame 1 to rotate and swing along the rotary base 601, thereby driving the action support arm 304 to swing at a preset angle with the frame 1 as the rotation axis, thereby realizing the action requirement of moving materials from one stack to another.

[0039] In summary, the utility model is a screw automatic feeding device which is provided with a frame 1, a screw drive mechanism 2, a screw transmission mechanism 3, a first rotary drive mechanism 4 and a feeding actuator 5; the screw drive mechanism 2 is provided in the frame 1, the screw transmission mechanism 3 is movably provided on the frame 1, and the screw drive mechanism 2 is driven and connected to the screw transmission mechanism 3; the first rotary drive mechanism 4 is provided on the side of the frame 1, and the screw transmission mechanism 3 is driven and connected to the first rotary drive mechanism 4; the feeding actuator 5 is provided on the side of the screw transmission mechanism 3, and the first rotary drive mechanism 4 is driven and connected to the feeding actuator 5.
