[0030] 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.
[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a chemical safety feeding device, including a body 1, which is an unpacking platform for a screw conveyor. The bottom of the body 1 is fixedly connected to a feeding cylinder 3 for conveying materials to the bottom of the screw conveyor. The inner wall of the middle part of the feeding cylinder 3 is provided with an adjustment component that can control the feeding amount to prevent excessive feeding from increasing the load on the screw conveyor and causing blockage. The adjustment component includes an adjustment plate 32 that controls the opening size to adjust the feeding amount. A fixing rod 31 that supports the adjustment plate 32 is fixedly connected to the middle part of the inner wall of the feeding cylinder 3. The adjustment plate 32 is hinged to the left side of the fixing rod 31. The bottom end of the adjustment plate 32 is provided with a guide groove 36 that provides a guide rod 37 to move and pull the adjustment plate 32 downward. The inner wall of the guide groove 36 is slidably connected to the guide rod 37 that pulls the adjustment plate 32 open.
[0032] Furthermore, the guide rod 37 is T-shaped, and the lower part of the guide rod 37 is inclined. By setting it to T-shape, the adjusting plate 32 can be pulled. By setting it to inclined, the adjusting plate 32 can be pulled downward to open, and the guide rod 37 can slide in the guide groove 36. The middle inner wall of the feed cylinder 3 is fixedly connected to a fixed plate 35 that provides support. The middle part of the fixed plate 35 has a through-hole and a positioning groove 39 for providing the round rod 38 to slide while restricting the round rod 38 to slide only up and down. The bottom of the fixed plate 35 is rotatably connected to a threaded rod 33 that drives the guide block 34 to move. The outer wall of the threaded rod 33 is threadedly connected to a guide block 34 that moves backward to push the round rod 38 in conjunction with the positioning groove 39, so that the round rod 38 drives the guide rod 37 to move downward. The upper inner wall of the guide block 34 is slidably connected to a round rod 38 that drives the guide rod 37 to move downward and pulls the adjusting plate 32 to rotate and open around the center of the fixed rod 31.
[0033] Reference Figure 2 , Figure 3 and Figure 5 The top of the feeding cylinder 3 is equipped with a shaking component that can shake the material piled on the filter screen 21 and make it fall automatically. The shaking component includes a motor 2 that drives the circular block 25 to rotate through the output shaft of the motor 2. The motor 2 is fixedly installed on the right side of the feeding cylinder 3. The left side of the output shaft of the motor 2 is fixedly connected to the circular block 25, which drives the protrusion 26 to rotate and pushes the slider 22 to move upward. The bottom of the slider 22 above the circular block 25 is not equipped with a spring 23, while the bottom of the other three sets of sliders 22 are equipped with springs 23.
[0034] Reference Figure 1 , Figure 3 and Figure 4The fixing plate 35 is T-shaped, and the top of the fixing plate 35 is arc-shaped. The T-shape of the fixing plate 35 can provide support, and the arc-shaped top can prevent material from accumulating at the top. The arc-shaped top can fall downwards along the arc. The threaded rod 33 passes through and is rotatably connected to the front surface of the feeding cylinder 3. The upper part of the guide block 34 is inclined. The round rod 38 is slidably connected to the inclined inner wall of the upper part of the guide block 34. The inclined movement of the upper part can push the round rod 38 to slide downwards along the inclined inner wall. The round rod 38 is also slidably connected to the inner wall of the positioning groove 39, so it can only move up and down. The guide block 34 and the positioning groove 39 cooperate to make the round rod 38 move downwards, pulling the inclined guide rod 37 to move and continue to pull the adjusting plate 32 to rotate and open. This controls the opening size of the adjusting plate 32 and controls the amount of material fed.
[0035] Furthermore, the bottom right end of the guide rod 37 is fixedly connected to the top left side of the round rod 38. The guide block 34 is U-shaped and slidably connected to the left and right sides of the fixed plate 35. The U-shape allows it to slidably connect to the outer wall of the fixed plate 35. The middle part of the round rod 38 is slidably connected to the inner wall of the positioning groove 39. There are two sets of adjusting plates 32, guide rods 37, and fixed rods 31. The two sets of adjusting plates 32, guide rods 37, and fixed rods 31 are symmetrically arranged with the center line of the fixed plate 35 as the axis of symmetry. By setting two sets and symmetrically arranging them, the two sets of adjusting plates 32 can be stably opened for feeding, and the amount of feeding can be stably controlled.
[0036] Reference Figure 2 , Figure 3 and Figure 5 The outer wall of the circular block 25 is fixedly connected to a protrusion 26 that pushes the slider 22 upward to vibrate. The inner top wall of the feeding cylinder 3 has multiple sets of grooves 24 providing space for the slider 22 to move. A filter screen 21 for screening passing materials is slidably connected to the top of the feeding cylinder 3. Sliders 22 that drive the filter screen 21 to move up and down are fixedly connected to the outer walls of the filter screen 21. Multiple sets of sliders 22 are slidably connected to the inner walls of corresponding grooves 24. The bottom end of the slider 22 is fixedly connected to a force that, when stretched by the slider 22, causes the slider 22 to return to its original position, thus causing the slider 22 and the filter screen 21 to vibrate up and down. Spring 23, the other end of which is fixedly connected to the inner wall of the bottom of the slide 24. Round block 25 is rotatably connected to the inner wall of the slide 24 on the right side of the feed cylinder 3. The outer wall of protrusion 26 is set as an arc surface. By setting it as an arc surface, it can squeeze slider 22, causing slider 22 to move upward along the arc surface and cooperate with spring 23 to reset, so that slider 22 drives filter screen 21 to shake up and down, which can prevent material from accumulating on filter screen 21. No additional manual intervention is required, which greatly saves labor costs, ensures the stability and reliability of the feeding process, and improves the feeding efficiency. The output shaft of motor 2 passes through and is rotatably connected to the right side of feed cylinder 3.
[0037] Working Principle: In use, first connect the external power supply and switch to the electrical equipment in this device. When adjusting the feeding amount, rotate the threaded rod 33. Since the threaded rod 33 is threadedly connected to the guide block 34, the rotation of the threaded rod 33 will drive the guide block 34 to move axially. Because the upper part of the guide block 34 is inclined and slidably connected to the round rod 38, and the middle part of the round rod 38 is restricted to sliding up and down within the positioning groove 39, the movement of the guide block 34 will push the round rod 38 downward along the positioning groove 39. The downward movement of the round rod 38 will pull... The guide rod 37 is fixedly connected to the top left side of the round rod 38 because its bottom right side is fixedly connected to the top left side of the round rod 38. The guide rod 37 slides in the guide groove 36 of the adjusting plate 32. At the same time, the lower part of the guide rod 37 is inclined. Therefore, the guide rod 37 will pull the adjusting plate 32 to rotate downward and open around the fixed rod 31. The opening angle of the adjusting plate 32 determines the opening degree of the discharge port of the discharge cylinder 3. By adjusting the opening angle of the adjusting plate 32, the discharge amount can be precisely controlled to prevent excessive discharge, avoid increasing the load on the screw conveyor, and prevent blockage caused by excessive discharge.
[0038] When motor 2 starts, the output shaft of motor 2 drives the circular block 25 to rotate. As the circular block 25 rotates, the protrusion 26 on its outer wall will also rotate. When the protrusion 26 rotates to the position of contacting the slider 22, the arc surface of the protrusion 26 will squeeze the slider 22, pushing the slider 22 to move upward along the slide groove 24. During the upward movement of the slider 22, the spring 23 will be stretched, allowing the spring 23 to store elastic potential energy. When the protrusion 26 continues to rotate and leaves the slider 22, the spring 23 will pull the slider 22 downward to reset due to the elastic restoring force. The up and down movement of the slider 22 will drive the filter screen 21 to move together, causing the filter screen 21 to produce an up and down shaking effect. This periodic up and down shaking can prevent material from accumulating on the filter screen 21, causing the material accumulated on the filter screen 21 to fall down automatically.
[0039] By adjusting the regulating plate 32 of the regulating component, the feeding amount is controlled to adapt to different production needs and the working capacity of the screw conveyor, preventing the screw conveyor from clogging due to excessive feeding. Finally, the material after screening and flow adjustment enters the screw conveyor from the feeding cylinder 3 for subsequent feeding and processing operations. Through the coordinated work of the regulating component and the shaking component, precise control of the feeding amount and automatic cleaning of the filter screen 21 are achieved, ensuring the safety, stability and efficiency of the entire feeding process. This avoids equipment clogging caused by excessive feeding amount and material accumulation caused by filter screen 21 clogging. At the same time, no additional manual intervention is required, improving feeding efficiency and the reliability of the production process.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
