Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and more specifically, to an automatic feeding device for aluminum profile processing. Background Technology

[0002] Aluminum profiles are materials with specific cross-sectional shapes made from aluminum alloys through processes such as extrusion. They are lightweight yet high-strength, with a density approximately one-third that of steel, yet still meeting the strength requirements of most structures. They are highly corrosion-resistant, and an oxide film easily forms on their surface, allowing for long-term use in various environments. Furthermore, they have good thermal conductivity, are easy to process, and can be molded into complex shapes through extrusion and bending. They are also recyclable and widely used in construction, industry, transportation, electronics, and many other fields. In the aluminum profile processing industry, the feeding process is a crucial link in the production line.

[0003] However, existing aluminum profile feeding devices have the following problems during use: Traditional aluminum profile loading relies heavily on manual labor, requiring workers to move stacked aluminum profiles one by one to the feeding end of the processing equipment. This method is not only labor-intensive but also inefficient, making it difficult to meet the demands of large-scale production. Furthermore, manual loading makes it difficult to guarantee the placement and positional accuracy of the aluminum profiles, easily leading to deviations in subsequent processing and affecting product quality. In addition, manual operation poses certain safety hazards, especially when handling long or heavy aluminum profiles, increasing the risk of collisions or injuries.

[0004] This invention enables fully automated feeding of aluminum profiles. Through the coordinated operation of various structures, it reduces manual intervention, lowers labor intensity, improves feeding efficiency and stability, adapts to various specifications of aluminum profiles, and ensures efficient operation of the production line.

[0013] A further preferred embodiment: the surface of the rotating wheel is provided with several slots, and paddles are fixedly installed on both the left and right sides of the outer end face of the slots. Beneficial effects

[0014] 1. By incorporating a receiving plate, lifting cylinder, and ejector plate, the stepped design of the receiving plate and ejector plate works together. Utilizing a tilted structure, gravity guides the movement of the aluminum profile, achieving gradual lifting and preventing swaying or tipping caused by excessive lifting at once. This enhances the stability of the conveying process. The lifting cylinder drives the ejector plate for precise lifting and lowering. Simultaneously, the ejector plate continuously ejects aluminum profiles from the feeding hopper during the lifting process, ensuring uninterrupted material supply and improving feeding efficiency. The mechanical coordination enables automated conveying, reducing manual intervention and labor intensity. Furthermore, it is adaptable to different specifications of aluminum profiles, enhancing the applicability of the device. 2. By incorporating a rotating wheel, slots, and paddles, the slots provide a stable clamping grip on the aluminum profile, ensuring it does not deviate during turning and maintaining consistent conveying posture. The paddles assist in pushing the aluminum profile, preventing it from getting stuck in the slots and reliably delivering it to the discharge port, thus preventing poor discharge. Simultaneously, the continuous rotation of the rotating wheel, combined with the spaced distribution of the slots, enables continuous and orderly output of the aluminum profile, allowing the feeding rhythm to precisely match subsequent processing steps, reducing waiting time, and improving overall production efficiency. This structural design enhances the stability and controllability of the discharge process, further ensuring the smoothness of automated feeding. 3. By setting up sliders and guide rods, the sliding cooperation between the sliders and guide rods can limit the movement trajectory of the fixed plate, avoid deviation or shaking during the lifting process, ensure that the ejector plate is accurately aligned with the slot between the receiving plates, and ensure the accuracy of the lifting position of the aluminum profile. This structure can disperse the driving force of the lifting cylinder, reduce wear caused by uneven force on the components, and extend the service life of the device. At the same time, the smooth lifting action can avoid impact on the aluminum profile, protect the integrity of the material, and make the entire lifting process more controllable, thereby improving the stability and reliability of the device operation. 4. In summary, this automatic feeding device for aluminum profile processing, through its structure including a receiving plate, lifting cylinder, ejector plate, transport frame, rollers, slots, and levers, achieves a fully automated process from stacked storage to precise delivery to the processing stage. The stepped cooperation of the receiving plate and ejector plate, combined with the drive of the lifting cylinder, utilizes gravity to achieve gradual lifting, avoiding the instability of a single lifting and ensuring continuous material supply. The transport frame achieves horizontal movement via a conveyor belt, ensuring a smooth transition of the aluminum profile to the discharge stage. The combination of rollers, slots, and levers precisely controls the discharge posture and rhythm, perfectly matching the feeding rhythm with subsequent processing. The coordinated operation of all structures significantly reduces manual intervention and labor intensity, while improving feeding efficiency and stability. Furthermore, it is adaptable to various aluminum profile specifications, enhancing the device's practicality and versatility, and providing a reliable guarantee for the efficient operation of the aluminum profile processing production line.

Detailed Implementation

[0020] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0021] Please see Figures 1-4In this embodiment of the present invention, an automatic feeding device for aluminum profile processing includes: a fixed frame 1, a lifting cylinder 2 fixedly installed on the rear side of the upper end of the fixed frame 1, a transport frame 3 fixedly installed on the upper rear side of the fixed frame 1, a discharge frame 4 fixedly installed on the left side of the upper end of the transport frame 3, a plurality of receiving plates 103 fixedly installed in the middle of the fixed frame 1, the lifting cylinder 2 is located behind the receiving plate 103, a fixed plate 201 is fixedly installed at the output end of the lifting cylinder 2, a plurality of ejector plates 202 are fixedly installed on the fixed plate 201 and the front end of the fixed plate 201, the ejector plates 202 are all L-shaped and are distributed in the slots formed between the receiving plates 103, and are movably connected to the receiving plates 103. The receiving plates 103 and the ejector plates 202 are all stepped, and the uppermost part of each is inclined backward. The setup includes a feed hopper 101 fixedly installed on the front upper side of the fixed frame 1; sliders 203 fixedly installed on both the left and right sides of the rear end of the fixed plate 201; and guide rods 204 fixedly installed on both the left and right sides of the rear end of the fixed plate 201. The sliders 203 and guide rods 204 are slidably connected. The upper and lower ends of the guide rods 204 are fixedly connected to the upper and lower ends inside the fixed frame 1. In the initial state, the output end of the lifting cylinder 2 is in the retracted position. The fixed plate 201 and the ejector plate 202 are located at the bottom of the slot between the receiving plates 103. The uppermost inclined stepped surface of the ejector plate 202 is located at the bottom of the receiving plate 103. Aluminum profiles are stacked in the feed hopper 101, and the bottommost aluminum profile falls onto the stepped surface of the frontmost ejector plate 202. The lifting cylinder 2 is activated, and its output… The end extends upward, driving the fixed plate 201 to move upward. At this time, the slider 203 at the rear end of the fixed plate 201 slides upward synchronously along the guide rod 204, ensuring that the fixed plate 201 rises smoothly. As the fixed plate 201 rises, the L-shaped ejector plate 202 moves upward from the slot between the receiving plates 103. The stepped surface of the ejector plate 202 lifts the aluminum profile upward. Since both the receiving plate 103 and the ejector plate 202 are stepped and their uppermost ends are inclined backward, each time they are lifted, the rear side of the upper end of the ejector plate 202 and the front side of the upper end of the receiving plate 103 form a straight ramp that slopes backward. This allows the aluminum profile to slide backward onto the subsequent receiving plate 103 due to the influence of gravity. At this time, the aluminum profile will be restricted by the rear ejector plate 202, making... The aluminum profile stops on the current receiving plate 103, and then the lifting motor 2 is driven to lower the fixed plate 201, allowing the aluminum profile to slide backward to the next step. This process is repeated to gradually lift the aluminum profile, avoiding instability caused by lifting too high at once. During the gradual lifting process, the foremost ejector plate 202 continuously lifts the aluminum profile in the feeding bin 101, achieving uninterrupted aluminum profile transportation. When the aluminum profile is transported to the rear, the ejector plate 202 lifts the aluminum profile to match the height of the transport frame 3. Under the continuous push of the ejector plate 202, the aluminum profile gradually slides towards the rear receiving plate 103, and then slides from the receiving plate 103 onto the transport frame 3. The transport frame 3 then starts, conveying the aluminum profile to the left.The aluminum profiles are conveyed by transport frame 3 to the discharge rack 4 on the left, and finally output from the discharge rack 4, completing one loading process.

[0022] In this embodiment of the utility model, a protective shell 102 is fixedly installed on the rear side of the feeding hopper 101. The protective shell 102 is fixedly installed above the receiving plate 103. The protective shell 102 is located above the receiving plate 103 and can play a lateral limiting and protection role for the stacked aluminum profiles, preventing the aluminum profiles from tipping over or scattering due to external collisions or their own center of gravity shift during the waiting process for feeding.

[0023] In this embodiment of the utility model, a motor 301 is fixedly connected to the right side of the front end of the transport frame 3. The motor 301 is fixedly connected to the right end of the fixed frame 1. A conveyor belt 302 is rotatably connected inside the transport frame 3. The output end of the motor 301 is fixedly connected to the rotating end of the conveyor belt 302. When the aluminum profile is transported to the transport frame 3, the motor 301 starts, and its output end drives the conveyor belt 302 to start running and transport to the left. At this time, the aluminum profile that is lifted is moved to the left by the conveyor belt under the friction of the conveyor belt 302. The conveyor belt 302 transports the aluminum profile to the discharge rack 4 on the left side of the transport frame 3.

[0024] In this embodiment of the present invention, a feed inlet 401 is provided at the right end of the discharge rack 4, and a discharge outlet 402 is provided at the front end of the discharge rack 4. A second motor 403 is fixedly installed at the left end of the discharge rack 4, and a rotating wheel 404 is fixedly installed at the output end of the second motor 403. The rotating wheel 404 is located above the left side of the feed inlet 401, and a plurality of slots 405 are provided on the surface of the rotating wheel 404. A lever 406 is fixedly installed on both the left and right sides of the outer end face of the slots 405. When the conveyor belt 302 transports the aluminum profile from the left side of the transport rack 3 to the end, the aluminum profile will enter the discharge rack through the feed inlet 401 at the right end of the discharge rack 4. At this time, the second motor 403 is in the starting state, driving the rotating wheel 404 to rotate. The front end of the aluminum profile entering the feed inlet 401 will contact the slots 404 of the rotating wheel 404. 05. The aluminum profile is inserted into the slot. As the rotating wheel 404 rotates continuously, the paddles 406 on both sides of the slot 405 play an auxiliary positioning and pushing role. As the rotating wheel 404 continues to rotate, the aluminum profile held by the slot 405 will be brought to the discharge port 402 at the front end of the discharge rack 4. When it rotates to the position of the discharge port 402, the aluminum profile is sent out from the discharge port 402 under the push of gravity and the paddles 406. The rotation speed of the rotating wheel 404 can be adjusted according to the overall feeding rhythm to ensure that it matches the conveying speed of the conveyor belt 302 and the ejection frequency of the lifting cylinder 2. When an aluminum profile is sent out from the discharge port 402, the next slot 405 of the rotating wheel 404 will be aligned with the feed port 401 to prepare to receive the next aluminum profile, realizing continuous automated feeding.

[0025] Working principle: In the initial state, the output end of the lifting cylinder 2 retracts, and the fixed plate 201 and the ejector plate 202 are located at the bottom of the slot between the receiving plate 103. The uppermost inclined stepped surface of the ejector plate 202 is lower than the bottom of the receiving plate 103. The aluminum profiles are stacked in the feeding bin 101, and the bottommost aluminum profile falls on the stepped surface of the frontmost ejector plate 202. The lifting cylinder 2 is activated, and the output end extends upward, driving the fixed plate 201 to rise smoothly along the guide rod 204. The L-shaped ejector plate 202 moves upward synchronously from the slot of the receiving plate 103, and its stepped surface will touch the bottom. The aluminum profile is lifted upwards. Since both the receiving plate 103 and the ejector plate 202 are stepped designs, and their uppermost ends are inclined backwards, a backward-sloping ramp is formed at the top during lifting. Under gravity, the aluminum profile slides backwards to the next receiving plate 103, while being limited by the rear ejector plate 202, stopping at the current step. The lifting cylinder 2 drives the fixing plate 201 to descend briefly, and the aluminum profile continues to slide backwards to a further step. This process is repeated to achieve a gradual lifting of the aluminum profile, avoiding instability caused by lifting too high at once. Simultaneously, the frontmost ejector plate 202... The feed hopper 101 continuously lifts the subsequent aluminum profiles to ensure uninterrupted material supply. When the aluminum profiles are conveyed step by step to the last side step, the ejector plate 202 lifts them to the same height as the transport frame 3. The aluminum profiles slide down the last side receiving plate 103 onto the conveyor belt 302. Then, the motor 301 starts, driving the conveyor belt 302 to rotate to the left. The aluminum profiles move synchronously with the conveyor belt under the action of friction and are conveyed to the discharge rack 4 on the left side of the transport frame 3. The aluminum profiles enter the interior through the feed port 401 at the right end of the discharge rack 4 and are locked into the pulley 404. Inside slot 405, motor 403 drives the rotating wheel 404 to rotate continuously. The paddles 406 on both sides of the slot assist in positioning and prevent deviation. As the rotating wheel 404 rotates, the clamped aluminum profile is brought to the discharge port 402 at the front end of the discharge rack 4. After reaching the position, it is pushed out from the discharge port 402 by gravity and the paddles 406 and enters the next processing step. The rotation speed of the rotating wheel 404 is matched with the speed of the conveyor belt 302 and the frequency of the lifting cylinder 2 to ensure that after the previous aluminum profile is sent out, the next slot 405 is aligned with the feed port 401, realizing continuous automated feeding.
