Description

Technical Field

[0001] This utility model relates to the field of feeding tray technology, and in particular to a rotary feeding tray. Background Technology

[0002] A rotary feeder is a widely used material directional conveying device in automated production lines. Its core function is to arrange disordered bulk materials (such as parts, capsules, bottle caps, etc.) in an orderly manner and directionally output them to the next process through rotational motion combined with a specific guiding structure. Traditional feeding methods, such as vibratory feeders, can achieve directional feeding, but they have drawbacks such as high noise, rapid wear, and easy damage to precision parts; while conveyor belts or manual arrangement are inefficient and inconsistent. The rotary feeder uses the horizontal rotation of the disc to move the material along the disc surface. With the help of centrifugal force, friction, and a pre-set guide groove or baffle structure, the material is gradually adjusted to the target posture during the movement, and finally completed directional conveying through the outlet channel.

[0003] During use, the parts in the feeding tray need to be rotated and transported in a directional manner. Therefore, it is necessary to block and restrict the parts in the feeding tray. Otherwise, if the feeding tray rotates too fast, the parts inside will be thrown out, and the parts cannot be transported in a directional manner. Utility Model Content

[0004] This utility model relates to a rotary feeding tray, in which the clamping plate and the limiting plate are connected by concave surfaces to fix and clamp the two ends of the feeding tray. The tight fit between the concave surfaces and the two ends of the feeding tray forms a stable clamping force, ensuring that the feeding tray can maintain a fixed position even when rotating at high speed, avoiding displacement or dislodgement due to centrifugal force or inertia. At the same time, when the parts in the feeding tray are rotated and oriented for conveying, the shielding cover can also automatically move up and down to block and restrict the upper end of the feeding tray. By dynamically adjusting the height of the shielding cover, it is ensured that the parts in the feeding tray are always under control during the conveying process. When the feeding tray rotates to a specific position, the automatic raising and lowering of the shielding cover can accurately prevent the disorderly movement or ejection of parts.

[0005] In a first aspect, this utility model provides a rotary feeding tray, specifically comprising: a fixed base; connecting holes respectively provided at the four corners of the fixed base; a fixed groove provided in the middle of the upper end of the fixed base; an annular rotating groove provided at the upper end of the fixed base; a drive motor fixedly installed in the fixed groove of the fixed base; a supporting rotating cylinder rotatably installed in the rotating groove; and a rotating plate fixedly installed at the upper end of the supporting rotating cylinder.

[0006] The upper end of the rotating plate has a rectangular groove, and two threaded grooves are respectively opened at both ends of the rectangular groove of the rotating plate; a fixed seat is fixedly installed in each of the six rectangular grooves of the rotating plate, and the structure of the six fixed seats is consistent; a groove is opened at the upper end of the fixed seat, an electric push rod is fixedly installed in the groove of the fixed seat, a bearing block is fixedly installed at the extension and retraction part of the electric push rod, and symmetrical sliders are fixedly installed at the bottom of the bearing block.

[0007] An arc-shaped clamping plate is fixedly installed on the side wall of the bearing block, and symmetrical guide rods are fixedly installed on the upper end of the clamping plate. A fixed cantilever is fixedly installed on the top of the bearing block, and a through circular hole is opened at the upper end of the fixed cantilever. A through electric rod is fixedly installed at the circular hole of the fixed cantilever, and a cover is fixedly connected to the lower end of the electric rod.

[0008] Furthermore, stabilizing grooves are evenly provided at the edge of the rotating plate, and a feeding tray is inserted in the stabilizing groove.

[0009] Furthermore, an arc-shaped limiting plate is fixedly installed at the outer end of the upper end of the stabilizing groove, and six parallel sliding grooves are opened on the rotating plate.

[0010] Furthermore, side strips are fixedly installed on both sides of the fixing base, and through bolts are inserted at both ends of the side strips. A fixing plate is fixedly installed on the side wall of the fixing base, and a through round hole is opened in the middle of the fixing plate.

[0011] This utility model provides a rotary feeding tray, which has the following beneficial effects:

[0012] In this invention, the rotary feeding tray uses a clamping plate and a limiting plate with concave surfaces to fix and clamp the two ends of the feeding tray. The tight fit between the concave surfaces and the two ends of the feeding tray creates a stable clamping force, ensuring that the feeding tray maintains a fixed position even under high-speed rotation, preventing displacement or dislodgement due to centrifugal force or inertia. At the same time, when the parts in the feeding tray are rotated and oriented for conveying, the shielding cover can also automatically move up and down to block and restrict the upper end of the feeding tray. By dynamically adjusting the height of the shielding cover, it is ensured that the parts in the feeding tray are always under control during the conveying process. When the feeding tray rotates to a specific position, the automatic raising and lowering of the shielding cover can accurately prevent the disorderly movement or ejection of parts.

[0013] Small parts are placed in the feeding tray. Depending on the tray's rotation speed, when the tray rotates slowly, the electric lever pulls the cover upwards, exposing the upper part of the tray for easy access. During low-speed operation, the upper part of the tray is open, allowing operators to directly access the parts without frequent tray starts and stops, thus improving efficiency. When the tray rotates quickly, the electric lever pushes the cover downwards, sealing the upper part of the tray to prevent parts from being thrown out during rotation. During rapid rotation, the cover closes the upper part of the tray, preventing centrifugal force from throwing parts out, reducing losses and safety hazards, and directing the parts to a designated location for easy access.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 4 :

[0024] This utility model proposes a rotary feeding tray, including: a fixed base 1; connecting holes are respectively opened at the four corners of the fixed base 1; large bolts are inserted into the connecting holes of the fixed base 1 and fixed to a fixed object to fix and restrict the fixed base 1; a fixing groove is opened in the middle of the upper end of the fixed base 1; an annular rotating groove 101 is opened at the upper end of the fixed base 1; the lower end of the supporting rotating cylinder 2 is rotatably installed in the rotating groove 101, so that the supporting rotating cylinder 2 will not tilt when it rotates, and the upper rotating plate 3 will also rotate smoothly to feed materials; a drive motor 102 is fixedly installed in the fixing groove of the fixed base 1; the upper end of the rotating shaft of the drive motor 102 is fixedly connected to the middle of the bottom of the rotating plate 3. When the drive motor 102 is turned on, the rotating shaft will rotate, and the rotating shaft will drive the rotating plate 3 to rotate. The feeding tray 302 on the rotating plate 3 will slowly rotate and directionally convey materials. The parts are oriented and transported to a designated position for easy access. A supporting rotating cylinder 2 is rotatably installed in the rotating groove 101. A rotating plate 3 is fixedly installed on the upper end of the supporting rotating cylinder 2. A rectangular groove is opened at the upper end of the rotating plate 3, and two threaded grooves are opened at both ends of the rectangular groove of the rotating plate 3. A stabilizing groove 301 is evenly opened at the edge of the rotating plate 3, and a feeding tray 302 is inserted in the stabilizing groove 301. Some smaller parts are placed in the feeding tray 302. An arc-shaped limiting plate 303 is fixedly installed at the outer end of the upper end of the stabilizing groove 301. The concave surface of the limiting plate 303 is in contact with the side wall of the feeding tray 302. The concave surface of the limiting plate 303 blocks and restricts the side wall of the feeding tray 302. Six parallel sliding grooves 304 are opened on the rotating plate 3. A fixing seat 4 is fixedly installed in each of the six rectangular grooves of the rotating plate 3, and the structure of the six fixing seats 4 is consistent. A groove is opened at the upper end of the fixing seat 4.

[0025] The fixed base 4 has side strips 401 fixedly installed on both sides, and through bolts are inserted at both ends of the side strips 401. The bolts on the side strips 401 are rotated and inserted into the threaded grooves of the rotating plate 3, thus fixing and restricting the side strips 401 and the fixed base 4. The fixed base 4 will not move during the rotation of the rotating plate 3, thus stably supporting the electric push rod 403. A fixed plate 402 is fixedly installed on the side wall of the fixed base 4, and a through circular hole is opened in the middle of the fixed plate 402. The telescopic part of the electric push rod 403 passes through the circular hole of the fixed plate 402. The electric push rod 403 is fixedly installed in the groove of the fixed base 4, and a bearing block 404 is fixedly installed at the telescopic part of the electric push rod 403. The bottom of component 4 is fixedly equipped with symmetrical sliders 405, which are slidably installed in the slide groove 304. When the support block 404 moves to adjust its position, the sliders 405 are restricted by the slide groove 304, preventing the support block 404 from tilting during sliding. Simultaneously, the clamping plate 406 also remains tilted. An arc-shaped clamping plate 406 is fixedly installed on the side wall of the support block 404. Using an electric push rod 403, the support block 404 and clamping plate 406 are moved towards the feeding tray 302. The concave surface of the clamping plate 406 contacts and clamps the side wall of the feeding tray 302. When the clamping plate 406 aligns with the limiting plate 303, it securely clamps both ends of the feeding tray 302, preventing it from being thrown off during the rotating conveying process. The feeding tray 302 is stably and directionally conveyed. The concave surface of the clamping plate 406 is in contact with the side wall of the feeding tray 302. Symmetrical guide rods 407 are fixedly installed on the upper end of the clamping plate 406. The guide rods 407 slide through the guide holes at both ends of the cover 410. When the cover 410 slides up and down, the guide rods 407 are restricted by the guide holes at both ends of the cover 410, so the cover 410 can only slide up and down to prevent it from tilting. Otherwise, the cover 410 will not be able to cover the feeding tray 302 stably. A fixed cantilever 408 is fixedly installed on the top of the bearing block 404. The upper end of the fixed cantilever 408 has a through round hole. A through electric rod 409 is fixedly installed in the round hole of the fixed cantilever 408. A cover 410 is fixedly connected to the lower end of the electric lever 409. The cover 410 is made of transparent material. When the clamping plate 406 moves and aligns with the limiting plate 303, the cover 410 also moves accordingly. At this time, the cover 410 is positioned above the feeding tray 302. Depending on the rotation speed of the feeding tray 302, when the feeding tray 302 rotates slowly, the electric lever 409 is used to pull the cover 410 upwards, exposing the upper part of the feeding tray 302 for easy access to the parts inside. When the feeding tray 302 rotates faster, the electric lever 409 is used to push the cover 410 downwards, sealing the upper part of the lower feeding tray 302 to prevent the parts inside from being thrown out when the feeding tray 302 rotates.The cover 410 has ear plates fixedly installed at both ends, and the ear plates have through guide holes.

[0026] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, side strips 401 are fixedly installed on both sides of the fixed base 4, and through bolts are inserted at both ends of the side strips 401. After removing the side strips 401 and the bolts, the fixed base 4 is fixedly welded to the rotating plate 3 to stabilize and restrict the fixed base 4. In this way, the fixed base 4 will not move when touched, avoiding the bolts from loosening after long-term use and failing to stabilize the fixed base 4, while also saving on component costs.

[0027] The working principle of this embodiment is as follows: In use, the electric push rod 403 moves the bearing block 404 and the clamping plate 406 towards the feeding tray 302. The concave surface of the clamping plate 406 abuts against the side wall of the feeding tray 302 and clamps it, preventing it from being thrown off during the rotation and conveying process of the feeding tray 302. This ensures stable directional conveying of the feeding tray 302. Smaller parts are placed in the feeding tray 302. The upper end of the drive motor 102 shaft is fixedly connected to the middle of the bottom of the rotating plate 3. When the drive motor 102 is turned on, the shaft will rotate, causing the rotating plate 3 to rotate. The feeding tray 302 on plate 3 rotates slowly to deliver the parts in a directional manner. Depending on the rotation speed of the feeding tray 302, when the feeding tray 302 rotates slowly, the electric lever 409 is used to pull the cover 410 upward, exposing the upper part of the feeding tray 302 for easy access to the parts inside. When the feeding tray 302 rotates faster, the electric lever 409 is used to push the cover 410 downward, sealing the upper part of the feeding tray 302 below to prevent the parts inside from being thrown out when the feeding tray 302 rotates, thus directionally delivering the parts in the feeding tray 302 to the designated position for easy access.
