Description

Technical Field

[0001] This utility model relates to the field of feeding technology, and in particular to an automatic feeding device. Background Technology

[0002] Currently, in automated feeding devices, powder cannot be evenly dispersed after entering the mold, resulting in accumulation that affects filling density and molding quality. Uneven powder distribution near the mold cavity wall can also lead to inconsistent density or structural defects in the molded parts. If powder adheres to the feeding hopper wall, it causes waste, contamination, or batch mixing. After pressing, unformed loose powder may remain in the mold cavity or gaps. When applying release agent, this residual powder mixes with the release agent to form a sticky sludge, which is then mixed into the new material in the next cycle, affecting the quality of the finished product.

[0003] Therefore, this utility model provides an automatic feeding device that can achieve uniform material distribution and eliminate powder residue in the feeding bin and the mold. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an integrated hydraulic cylinder four-column hydraulic press.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "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.

[0029] Example 1, referring to Figures 1-3 An automatic feeding device includes a feeding platform 10, a feeding device 2, and a pushing device 3. The feeding platform 10 has a discharge port 11. The feeding device 2 is slidably mounted on the feeding platform 10. The feeding device 2 includes multiple feeding pipes 20 and a holding box 22. The multiple feeding pipes 20 are connected to the holding box 22. A pneumatic vibrator 24 is installed on the feeding pipes 20. The bottom end of the holding box 22 has a discharge port, which is in contact with the feeding platform 10 and corresponds to the discharge port 11. The pushing device 3 includes a pushing cylinder 31 and a pushing cylinder fixing seat 30. The pushing cylinder 31 is fixedly connected to the pushing cylinder fixing seat 30. The output end of the pushing cylinder 31 is connected to the feeding device 2. A suction device is fixedly connected to the front end of the holding box 22.

[0030] With the above scheme, the feeding device 2 can be transported back and forth on the upper plane of the feeding platform 10 by the pushing device 3. The discharge port below the holding box 22 corresponds to the discharge port 11 on the feeding platform 10, so that all the material in the holding box 22 can be placed in the mold for pressing. In this embodiment, there are three sets of feeding pipes 20. The three sets of feeding pipes 20 are evenly arranged to deliver the powder to the holding box 22 more evenly, preventing the situation where there is no powder on both sides of the holding box 22. The pneumatic vibrator 24 installed on the feeding pipe 20 is mainly used to automatically prevent the powder from adhering, blocking and bridging during the conveying process of the feeding pipe 20 and the holding box 22, improve the powder flowability and reduce manual intervention. In this embodiment, the pneumatic vibrator 24 can be any type of pneumatic vibrator, such as a linear vibrator, a rotary vibrator, an impactor, or an internal vibrator. After pressing, if there is still powder remaining on the feeding platform 10, the suction device can pick up the remaining powder to ensure the cleanliness of the surface of the feeding platform 10 at the start of the next pressing cycle. The suction device is controlled by an external control system to absorb the remaining powder into the recycling bin, thereby realizing the recycling of the powder.

[0031] In Example 2, to better facilitate the operation of the feeding device 2, the pushing device 3 is specifically connected as follows: the output end of the pushing cylinder 31 passes through the pushing cylinder fixing seat 30. A first connecting plate 33 is connected to the output end of the pushing cylinder 31. Two sets of pushing plates 35 are fixedly connected to the first connecting plate 33 near the extension direction of the feeding device 2. The two sets of pushing plates 35 are fixedly connected to the pushing cylinder fixing seat 30 via connecting seats. A second connecting plate 36 is connected to the other end of the two sets of pushing plates 35. The second connecting plate 36 is fixedly connected to the material container 22. To guide the first connecting plate 33, a guide rod 32 is provided between the first connecting plate 33 and the pushing cylinder fixing seat 30. When the pushing cylinder 31 pushes the first connecting plate 33 to reciprocate, it drives the pushing plates 35 and the second connecting plate 36 to reciprocate, ultimately causing the material container 22 to move repeatedly on the feeding platform 10.

[0032] Example 3, continue to refer to Figure 3 To facilitate material feeding from the material container 22, in this embodiment, the material container 22 is configured with a polygonal cross-section, and the included angle between the two rear side walls of the material container 22 is an acute angle. The bottom end of the feeding pipe 20 is connected to the upper rear side wall of the material container 22. The feeding pipe 20 is configured to be inclined, and the rear side wall of the material container 22 that connects to the feeding pipe 20 is also configured to be inclined to facilitate connection with the feeding pipe 20. The other rear side wall of the material container 22 is also configured to be inclined to facilitate the conveying of powder into the mold through the discharge port 11.

[0033] In Example 4, to level the powder in the material container 22, a leveling port is provided at the top of the material container 22. A leveling cylinder 21 is connected to the upper end of the leveling port, and the output end of the leveling cylinder 21 extends into the interior of the material container 22. The leveling cylinder 21 is a rodless cylinder, and a slide table 211 slides at the bottom of the rodless cylinder. A pusher plate is fixed at the bottom of the slide table 211. The pusher plate levels the powder entering the material container 22, so that the powder in the material container 22 is evenly distributed.

[0034] In Example 5, in order to recover the residual powder on the feeding platform 10, the suction device specifically includes a mounting plate 40, a first suction pipe 41 and a second suction pipe 42. The mounting plate 40 is installed at the front end of the material container 22. A main suction pipe is installed at the front end of the mounting plate 40. The two sides of the main suction pipe are connected to the first suction pipe 41. The bottom of the two first suction pipes 41 and the main suction pipe is connected to the horizontal second suction pipe 42. The bottom of the second suction pipe 42 is provided with multiple suction holes.

[0035] The suction main pipe in the suction device is connected to the external recycling box. The parameters of the suction device are controlled by the controller. The two sets of first suction pipes 41 and second suction pipes 42 are arranged in a triangle, which helps to stabilize the structure of the suction device. The bottom of the second suction pipe 42 has multiple suction holes. Specifically, the suction holes are circular holes. The advantage of setting them as circular holes is that the airflow can form a uniform radial flow field when passing through the circular holes, avoiding local vacuum fluctuations. The circular edge can reduce airflow separation, reduce turbulent energy loss, and maintain stable adsorption force. Under the same opening area, the effective diameter of the circular hole is larger. The high-speed rotating airflow forms a centrifugal force field in the circular hole, which can adsorb large powder particles.

[0036] The bottom of the second suction pipe 42 is higher than the bottom of the material container 22. This is to ensure that the discharge port at the bottom of the material container 22 corresponds to the discharge port 11 opened on the feeding platform 10.

[0037] In Example 6, to allow the feeding device 2 to slide more smoothly on the feeding platform 10, slide rails 12 are fixed on both sides of the feeding platform 10. A material box guide plate 13 slides on the slide rails 12, and the other side of the material box guide plate 13 is connected to both ends of the material container 22. In this example, the material box guide plate 13 includes a guide plate one and a guide plate two. Guide plate one is fixedly connected to a slider, which slides on the slide rail 12. Guide plate two is connected to the material container 22, and guide plate one and guide plate two are connected by an arc-shaped connecting block.

[0038] In Example 7, to maintain the balance of the feeding platform 10 after the material container 22 is fed, a clamping cylinder 34 is fixed to the front end of the first connecting plate 33. The output end of the clamping cylinder 34 is connected to the two sets of push plates 35 through a cylinder connecting shaft. After the material container 22 is fed, it has a certain weight. To prevent the feeding platform 10 from tilting to the heavier side, the clamping cylinder 34 is set to clamp the material container, ensuring that the material container 22 remains stable during the conveying or pressing process.

[0039] The working process of this utility model is as follows: Powder enters the holding box 22 from the feeding pipe 20. The pneumatic vibrator 24 installed on the feeding pipe 20 increases the flow of powder in the feeding pipe 20, so that the powder in the feeding pipe 20 quickly enters the holding box 22. After the holding box 22 is full, feeding stops. The pusher cylinder 31 pushes the first connecting plate 33 to drive the second connecting plate 36 to slide on the feeding platform 10. The discharge port at the lower end of the holding box 22 corresponds to the discharge port 11 on the feeding platform 10. The powder enters the mold and waits for the powder to settle. When all the powder enters the mold, the pusher cylinder 31 begins to return, driving the material container 22 back. During the return process, the second suction pipe 42 in the suction device absorbs and recovers the powder scattered on the feeding platform 10. When the powder is pressed into shape and ejected from the mold, the pusher cylinder 31 pushes the material container 22 to transport the powder along the feeding platform 10. At this time, the front end of the material container 22 can push the finished product away from the discharge port 11, and the material in the material container 22 enters the mold from the discharge port 11 to start pressing. This cycle continues.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
