Description
Technical Field
[0001] This utility model relates to the field of ramie stalk processing technology, and in particular to an automatic ramie stalk feeding and dispensing device. Background Technology
[0002] Ramie processing requires the continuous feeding of ramie stalks into stripping equipment (such as a ramie beater) for segmentation, cutting, and scraping. Currently, feeding ramie into the stripping equipment is mainly done manually.
[0003] However, manually handling ramie stalks is labor-intensive, inefficient, and prone to fiber contamination or breakage. While using a conveyor belt requires manual intervention to place the ramie stalks row by row onto the belt, it is necessary to innovate and improve upon the existing conveyor belt structure by adding an automatic material feeding device. This would shorten the material movement path and reduce overall production costs and safety risks. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic feeding and dispensing device for ramie stalks.
[0005] The technical solution of this utility model is: an automatic feeding device for ramie stalks, including a base, two support plates arranged in parallel on the base, a feeding channel between the two support plates, and a conveying mechanism in the feeding channel;
[0006] The bottom of the feeding pipe is connected to the support plates on both sides, and the lower opening of the feeding pipe is located above the conveying mechanism. The top of the feeding pipe is equipped with a hopper that communicates with it. The hopper is equipped with an anti-blocking mechanism to prevent the ramie stalks inside from blocking the inlet of the feeding pipe.
[0007] The tensioning component is mounted on the base. The movable end of the tensioning component is connected to the material distribution slider A. The end of the material distribution slider A away from the tensioning component is inserted into the feeding tube and slidably connected to it.
[0008] Material distribution slider B passes through the material distribution pipe along the end away from material distribution slider A and is slidably connected to it. Material distribution slider B is located above material distribution slider A. A storage channel is set between material distribution slider A and material distribution slider B for temporary storage of only one row of ramie stalks.
[0009] And drive component A, which is set on the base and drives the connecting material distribution slider B. The material distribution slider B pushes the material distribution slider A while passing through the feeding pipe and causes the ramie rod in the storage channel to fall onto the conveying mechanism.
[0010] Preferably, the conveying mechanism includes a conveyor belt, an electric drum, and a driven roller. The electric drum and the driven roller are located at both ends of the feeding channel. The two ends of the electric drum are connected to the support plates on the corresponding sides, and the two ends of the driven roller are rotatably connected to the support plates on the corresponding sides. The conveyor belt drives the movable end of the electric drum and the driven roller.
[0011] Preferably, several partitions are spaced apart on the conveyor belt to form several separation grooves parallel to the conveying direction of the conveyor belt.
[0012] Preferably, several locking blocks are evenly spaced within the separation groove to push the ramie stalks within the separation groove.
[0013] Preferably, the tensioning assembly includes a bracket, a slide bar, and a spring. The bracket is connected to the base, and the two ends of the slide bar are respectively connected to the outer wall of the feed tube and the bracket. A baffle is provided on the slide bar and is slidably connected thereto. The baffle is connected to the material distribution slider A, and the spring is sleeved on the slide bar. The two ends of the spring abut against the baffle and the bracket, respectively.
[0014] Preferably, the anti-blocking mechanism includes a distributing platform, a movable plate, a slide, a connecting rod, and a drive assembly B. The connecting rod includes two sets. The distributing platform is centrally located inside the hopper, and the top of the distributing platform has a smooth arc surface. The two movable plates are rotatably located on both sides of the distributing platform. A hanging rod is located at the bottom of the distributing platform, and a limiting plate is located at the bottom of the hanging rod. The slide is slidably located on the hanging rod. The two sets of connecting rods rotatably connect the slide and the movable plate on the corresponding side. The drive assembly B is located inside the distributing platform and drives the slide to rise or fall.
[0015] Preferably, as the carriage gradually approaches the limiting plate, the distance between the lower ends of the two movable plates and the inner wall of the feed tube gradually decreases.
[0016] Compared with the prior art, the present invention has the following beneficial technical effects:
[0017] Multiple sets of partitions are arranged parallel to each other on the conveyor belt, forming independent separation grooves between adjacent partitions. These grooves separate ramie stalks. A clamping plate inside the separation groove pushes the tail end of the ramie stalk as it enters the stripping equipment. Two separating sliders, A and B, are used. When slider B is open, slider A is closed, allowing the lower layer of ramie stalks in the hopper to fall onto slider A. Subsequently, slider B closes to cooperate with slider A in separating the ramie stalks that have fallen onto slider A from their upper layers. The ramie stalks are completely independent. As the material distribution slider B pushes the material distribution slider A, the material distribution slider B, in its closed state, lowers the ramie stalks on the material distribution slider A into the separation tank, realizing automatic material distribution and unloading. During the return and reset process, the material distribution slider B automatically drives the material distribution slider A to return and reset. At the same time, this utility model is equipped with an anti-blocking mechanism in the hopper. The anti-blocking mechanism intermittently discharges material into the lower feed pipe to avoid blockage inside the feed pipe. In the working state, the anti-blocking mechanism will cause the ramie stalks in the hopper to vibrate, further improving the smoothness of its unloading. Attached Figure Description

[0023] Example 1
[0024] like Figures 1-4As shown, this utility model proposes an automatic ramie stalk feeding and dispensing device, including a base 1, a feeding pipe 3, a tensioning component, a dispensing slider B10, and a driving component A11. Two support plates 2 are arranged parallel to each other on the base 1, and a feeding channel is set between the two support plates 2. A conveying mechanism is set in the feeding channel. The conveying mechanism includes a conveyor belt 13, an electric roller 14, and a driven roller 15. The electric roller 14 and the driven roller 15 are located at opposite ends of the feeding channel. The two ends of the electric roller 14 are connected to the support plates 2 on the corresponding sides, and the two ends of the driven roller 15 are rotatably connected to the support plates 2 on the corresponding sides. The conveyor belt 13 drivesly connects the movable end of the electric roller 14 and the driven roller 15. Several partitions 131 are spaced apart on the conveyor belt 13 to form several separation grooves parallel to the conveying direction of the conveyor belt 13. Several locking blocks 132 are evenly spaced apart in the separation grooves to push the ramie stalks in the separation grooves. The bottom of the feeding pipe 3 is connected to the two side support plates 2, and the lower opening of the feeding pipe 3 is located above the conveying mechanism. The top of the feeding pipe 3 is provided with a hopper 4 connected to it. The hopper 4 is provided with an anti-blocking mechanism to prevent the ramie stalks inside from blocking the inlet of the feeding pipe 3. The anti-blocking mechanism includes a distribution platform 16, movable plates 17, a slide 20, connecting rods 21, and a drive assembly B22. The connecting rods 21 consist of two sets. The distribution platform 16 is centrally located within the hopper 4, with a smooth arc surface at its top. Two movable plates 17 are rotatably mounted on either side of the distribution platform 16. A hanging rod 18 is located at the bottom of the distribution platform 16, with a limiting plate 19 at its bottom. The slide 20 is slidably mounted on the hanging rod 18. The two sets of connecting rods 21 rotatably connect the slide 20 to the corresponding movable plates 17. The drive assembly B22 includes, but is not limited to, an electric push rod B. The body of the electric push rod B is located within the distribution platform 16, and its output end is connected to the slide 20. As the slide 20 gradually approaches the limiting plate 19, the distance between the lower ends of the movable plates 17 on both sides and the inner wall of the discharge pipe 3 gradually decreases, and several protective pads are provided at the ends of the movable plates 17 furthest from the distribution platform 16. The tensioning assembly is mounted on the base 1. The movable end of the tensioning assembly is connected to the material distribution slider A5. The end of the material distribution slider A5 furthest from the tensioning assembly is inserted into the feed tube 3 and slidably connected thereto. The tensioning assembly includes a bracket 7, a slide rod 8, and a spring 9. The bracket 7 is connected to the base 1. Both ends of the slide rod 8 are connected to the outer wall of the feed tube 3 and the bracket 7, respectively. A baffle 6 is slidably connected to the slide rod 8 and is connected to the material distribution slider A5. The spring 9 is sleeved on the slide rod 8, and both ends of the spring 9 abut against the baffle 6 and the bracket 7, respectively. The material distribution slider B10 passes through the feed tube 3 along the end furthest from the material distribution slider A5 and slidably connected thereto. The material distribution slider B10 is located above the material distribution slider A5. A storage channel for temporarily storing only one row of ramie stalks is provided between the material distribution slider A5 and the material distribution slider B10.The drive assembly A11 includes, but is not limited to, an electric push rod A. The body of the electric push rod A is mounted on the base 1. The output end of the electric push rod A is connected to the material distribution slider B10. The material distribution slider B10 pushes the material distribution slider A5 while passing through the discharge pipe 3, causing the ramie stalks in the storage channel to fall into the corresponding separation groove on the conveyor belt 13.
[0025] In this embodiment, ramie stalks are stacked in the hopper 4, with the lower layer of ramie stalks falling onto the movable plates 17 on both sides. The electric push rod B is activated, which pushes the slide 20 to slide back and forth. This causes the movable plates 17 on both sides to reciprocate and expand / contract via the connecting rod 21. When the movable plates 17 retract, the lower layer of ramie stalks in the hopper 4 descends and enters the discharge pipe 3. When the movable plates 17 expand, they cut off the descending of the upper layer of ramie stalks. Furthermore, the movable plates 17 in motion cause the upper layer of ramie stalks to vibrate, achieving vibration discharge and preventing blockage in the discharge pipe 3. The ramie stalks in the feeding pipe 3 are stacked on the separating slider A5. The bottom layer accommodates about 10 ramie stalks, and there is a significant height difference between the upper and lower layers of ramie stalks. At this time, the electric push rod A is activated, which drives the separating slider B10 to slide and close the space above the separating slider A5. During the closing process, the separating slider B10 pushes the second layer of ramie stalks above the separating slider A5 upwards, so that there is only one row of ramie stalks between the separating slider A5 and the separating slider B10. Then, the separating slider B10 continues to slide towards the support 7, and the separating slider B10 begins to push the separating slider A5, so that the ramie stalks on the separating slider A5 fall one by one and fall into the corresponding separation tank in sequence. The electric roller 14 is activated and drives the conveyor belt 13 to run. The conveyor belt 13 uses the clamping block 132 to push the ramie stalks that have fallen into its separation tank into the stripping equipment. Then, the material distribution slider B10 slides back to its original position, and at the same time, the material distribution slider A10 is synchronously reset under the tension of the spring 9. This cycle can be repeated.
[0026] Example 2
[0027] like Figure 3 As shown, the present invention proposes an automatic ramie stalk feeding device. Compared with the first embodiment, the baffle 6 is provided with an iron plate on the side near the feeding pipe 3, and the feeding slider B10 is provided with a magnet 12 that cooperates with the iron plate at the end facing the support 7. The magnet is an electromagnet.
[0028] In this embodiment, since the spring 9 will gradually weaken and eventually fail after frequent extension and contraction, in order to ensure that the device can continue to operate stably after the spring 12 fails, when it is found that the material distribution slider A5 does not respond to the return in time, the electromagnet's electric control switch is immediately turned on, and the electromagnet attracts the iron plate, so that the material distribution slider A5 returns to its rapid reset.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
