Description

Technical Field

[0001] This utility model relates to a feeding device. Background Technology

[0002] In metal parts manufacturing, such as forging and screw fastening, conveying mechanisms are used to transport products. Generally, a vibrating feeder is used to load the material into a vibrating feed chute, and then a robotic arm grabs it at the rear. For structures that cannot be directly grabbed by the robotic arm from the feed chute, a receiving mechanism is used to catch the material before it is removed for processing. When receiving a single product, a blocking mechanism is installed on the feed chute to prevent material from entering. This blocking mechanism typically uses a cylinder and a stop lever. The cylinder moves the stop lever to obstruct the material in the feed chute, and then the receiving mechanism catches it at the rear. This method has the following drawbacks:

[0003] 1. The receiving mechanism and the blocking mechanism need to be linked, which makes the control and debugging relatively difficult and the debugging efficiency relatively low;

[0004] 2. In order to ensure that the receiving mechanism can receive the material when the barrier is released, a certain amount of time will be reserved. During this process, the receiving efficiency will be affected, which in turn will affect the subsequent processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding device that improves the convenience and stability of feeding, and increases the efficiency of receiving and processing materials.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a feeding device, including a frame, a feeding trough mounted on the frame, a blocking mechanism and a pushing mechanism, wherein the pushing mechanism is disposed opposite to the blocking mechanism;

[0007] The blocking mechanism includes a connecting plate, an elastic element, and a baffle. The connecting plate is mounted on the frame above the rear side of the feeding trough, and the left side of the connecting plate is rotatably connected to the frame. The baffle is installed on the front right side of the connecting plate, and the baffle is positioned directly opposite the feeding trough. The elastic element is mounted on the frame, and the bottom of the elastic element abuts against the connecting plate. The elastic element pushes the bottom right side of the connecting plate downwards, causing the baffle to abut against the inside of the feeding trough.

[0008] The pushing mechanism includes a push plate and a push plate drive. The left end of the push plate is located below the right end of the connecting plate. The push plate drive drives the push plate to move left and right. When the push plate moves to the left, it pushes the right end of the connecting plate to rotate upward and causes the baffle to move upward away from the bottom of the feeding trough.

[0009] In the above technical solution, the right side of the connecting plate is a first guide slope, which is inclined upward from left to right; the left side of the push plate is a second guide slope, which is inclined upward from left to right and is located below the first guide slope; when the push plate moves to the left, the second guide slope contacts the first guide slope and pushes the right end of the connecting plate to rotate upward.

[0010] In the above technical solution, a notch is provided on the frame at the rear end of the feeding trough, and a vertical plate is provided at the bottom left end of the connecting plate. The vertical plate is inserted into the notch, and the vertical plate is rotatably connected to the notch via a connecting pin.

[0011] In the above technical solution, a bracket is provided on the frame on the rear side of the connecting plate, the front end of the bracket is located above the connecting plate, the elastic element is installed on the bracket, and the elastic element is located above the right side of the connecting pin.

[0012] In the above technical solution, the elastic element is a spring pin.

[0013] In the above technical solution, the elastic element includes a pressure rod and a spring. The bracket is provided with a through hole. The middle part of the pressure rod is movably inserted into the through hole. The bottom of the pressure rod is provided with a pressure head. The top of the pressure rod is provided with a limiting nut. The limiting nut is located above the bracket above the through hole. The pressure head is located below the bracket below the through hole.

[0014] The spring is sleeved on the pressure rod, with the top of the spring abutting against the bottom surface of the bracket below the through hole and the bottom of the spring abutting against the top surface of the pressure head. The spring pushes the pressure rod downward and causes the pressure head to abut against the top surface of the connecting plate.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. In this utility model, an elastic element is used to push a baffle to press against the material in the feeding trough, thereby blocking the material. Then, the movement of the push plate in the pushing mechanism pushes the baffle to move upward and release the material in the feeding trough. In this way, the receiving mechanism and the push plate can be directly combined. When the receiving mechanism and the push plate move synchronously and dock with the feeding trough, the baffle can be pushed to open the feeding trough, allowing the product in the feeding trough to be received immediately. When the push plate moves away from the connecting plate, the receiving mechanism moves away from the feeding trough, and the baffle also quickly blocks the material in the receiving trough to prevent the material from being received. This realizes the linkage of receiving and blocking, improves the stability and convenience of receiving, and also improves the efficiency of subsequent receiving and processing.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: See Figure 1-4 As shown, a feeding device includes a frame 1, a feeding trough 2 mounted on the frame 1, a blocking mechanism and a pushing mechanism, wherein the pushing mechanism is disposed opposite to the blocking mechanism;

[0025] The blocking mechanism includes a connecting plate 3, an elastic element 4, and a baffle 5. The connecting plate 3 is disposed on the frame 1 above the rear side of the feeding trough 2. The left side of the connecting plate 3 is rotatably connected to the frame 1. The baffle 5 is installed on the front right side of the connecting plate 3, and the baffle 5 is positioned directly opposite the feeding trough 2. The elastic element 4 is installed on the frame 1, and the bottom of the elastic element 4 abuts against the connecting plate 3. The elastic element 4 pushes the bottom right side of the connecting plate 3 downward, so that the baffle 5 abuts against the inside of the feeding trough 2.

[0026] The pushing mechanism includes a push plate 6 and a push plate driving component 7. The left end of the push plate 6 is located below the right end of the connecting plate 3. The push plate driving component 7 drives the push plate 6 to move left and right. When the push plate 6 moves to the left, it pushes the right end of the connecting plate 3 to rotate upward and moves the baffle 5 upward away from the bottom of the feeding trough 2. When the push plate moves to the right, the elastic element pushes the right end of the connecting plate to move downward, so that the bottom of the baffle is close to or abuts against the bottom surface of the receiving trough.

[0027] In this embodiment, during actual use, the vibrating feeding plate 8 feeds the product into the feeding trough from the left end. The material is conveyed from the left end of the feeding trough to the right, and the baffle is located near the right end of the feeding trough. A receiving mechanism 9 is located on the right side of the feeding trough. The receiving mechanism is connected to the push plate drive component. When the push plate drive component moves the push plate left and right, it simultaneously drives the receiving mechanism to move left and right. When the product is conveyed from the left end of the receiving trough to the right, it is blocked by the baffle. During receiving, the push plate drive component pushes the push plate and the receiving mechanism to the left. When the push plate moves to the left, it pushes the right end of the connecting plate to rotate upwards, compressing the elastic element. When the right end of the connecting plate rotates upwards, the baffle moves upwards away from the bottom of the receiving trough, allowing the product to move to the right through the baffle. When the receiving mechanism abuts against the right end of the receiving trough, the push plate drive component stops working, and the baffle is fully raised. The receiving mechanism includes a receiving plate 10 and a lifting component. The left end of the receiving plate has a receiving cavity 11 directly facing the receiving trough. The lifting component includes a lifting plate 12 and a lifting cylinder 13. The lifting plate is positioned below the receiving cavity, and the lifting cylinder pushes the lifting plate to move up and down. When the left end of the receiving plate contacts the right end of the receiving trough, the receiving trough is directly facing the receiving cavity. At this time, the baffle is fully raised, and the product in the receiving trough moves to the right and enters the receiving cavity. Then, the push plate drive component drives the push plate and the receiving mechanism to move to the right. During this process, the push plate moves away from the connecting plate. At this time, the elastic component pushes the right end of the connecting plate downward, causing the bottom of the baffle to approach the bottom of the receiving trough, blocking the receiving trough and limiting the product by the baffle plate, preventing the product from moving to the right and falling out of the receiving trough. After the receiving mechanism moves to the right and is in place, the output shaft of the lifting cylinder extends, driving the lifting component to lift the product in the receiving cavity, making it easier to grab the product later. In this method, when the push plate moves to the left to receive the material, the baffle is simultaneously lifted to remove obstruction from the product, allowing the product to move to the right and enter the receiving mechanism for receiving. After receiving is complete, as the receiving mechanism moves away from the receiving trough, the push plate also moves away from the connecting plate, and the baffle automatically blocks the receiving trough. This ensures the stability of receiving, eliminating the need for separate adjustments, improving the stability and convenience of receiving, as well as increasing receiving efficiency and subsequent processing efficiency. Furthermore, the simple structure reduces the need for a drive mechanism, resulting in lower costs.

[0028] See Figure 4As shown, the right side of the connecting plate 3 is a first guide slope 14, which is inclined upward from left to right. The left side of the push plate 6 is a second guide slope 15, which is inclined upward from left to right and is located below the first guide slope 14. When the push plate 6 moves to the left, the second guide slope 15 contacts the first guide slope 14 and pushes the right end of the connecting plate 3 to rotate upward.

[0029] In this embodiment, the push plate drive component is a cylinder. When the push plate moves to the left, the second guide slope and the first guide slope come into contact. Preferably, the first guide slope and the second guide slope are parallel. Both the second guide slope and the first guide slope are inclined. In this way, when the push plate moves to the left, the second guide slope will squeeze the first guide slope, pushing the first guide slope upward, driving the right end of the connecting plate to rise, and simultaneously driving the baffle to move upward away from the bottom surface of the receiving groove, opening the right end of the receiving groove, so that the product can move to the right along the receiving groove and enter the receiving mechanism.

[0030] See Figure 4 As shown, a notch 16 is provided on the frame at the rear end of the feeding trough 2, and a vertical plate 17 is provided at the bottom left end of the connecting plate 3. The vertical plate 17 is inserted into the notch 16, and the vertical plate 17 is rotatably connected to the notch 16 via a connecting pin 18.

[0031] In this embodiment, the left end of the connecting plate is inserted into the notch via the upright plate and is rotatably connected to the connecting pin. This allows the right end of the connecting plate to rise when a pushing force is applied to its bottom, thus raising the baffle. After the pushing force on the right end of the connecting plate disappears, the elastic element pushes the right end of the connecting plate downwards, causing the baffle to be positioned close to or against the bottom surface of the receiving groove, blocking the product in the receiving groove on the left side of the baffle.

[0032] See Figure 1-4 As shown, a bracket 19 is provided on the frame on the rear side of the connecting plate 3. The front end of the bracket 19 is located above the connecting plate 3. The elastic element 4 is installed on the bracket 19 and is located above the right side of the connecting pin 18.

[0033] The bracket is designed for the installation of the elastic element, which presses against the connecting plate, applying downward pressure to the right end of the connecting plate and causing the baffle to approach or abut against the bottom surface of the receiving trough.

[0034] In this embodiment, the elastic element is a spring pin.

[0035] Example 2: See Figure 5As shown, a feeding device is described in this embodiment. Its structure is basically similar to that of Embodiment 1, except that: the elastic element includes a pressure rod 20 and a spring 21; a through hole 22 is provided on the bracket 19; the middle part of the pressure rod 20 is movably inserted into the through hole 22; a pressure head 23 is provided at the bottom of the pressure rod 20; a limiting nut 24 is provided at the top of the pressure rod 20; the limiting nut 24 is located above the bracket 19 above the through hole 22; and the pressure head 23 is located below the bracket 19 below the through hole 22.

[0036] The spring is sleeved on the pressure rod, with the top of the spring abutting against the bottom surface of the bracket below the through hole and the bottom of the spring abutting against the top surface of the pressure head. The spring pushes the pressure rod downward and causes the pressure head to abut against the top surface of the connecting plate.

[0037] In this embodiment, instead of using a spring pin, a combination of a pressure rod and a spring is used for the elastic element. The spring force is used to apply downward pressure to the right end of the connecting plate, so that when the right end of the connecting plate is not subjected to upward pushing force, the baffle will press into the receiving groove to prevent the product from moving to the right and falling out of the receiving groove.

[0038] Preferably, the bottom of the pressure head has a spherical contact surface, so that the pressure head is always in contact with the connecting plate when the connecting plate rotates, and always applies downward pressure to the connecting plate.
