Abstract
Description
Technical Field
[0001] This utility model relates to the field of extruder technology, and in particular to an extruder feeding device. Background Technology
[0002] An extruder is a device used to process materials into a puffed form through high temperature and high pressure. It is commonly used in food processing, such as the production of puffed foods (e.g., potato chips, popcorn), and can also be used for the puffing of other materials such as plastics and rubber.
[0003] In the prior art, Chinese patent application number 202320580156.6 discloses a feeding device for an extruder, relating to the field of extruder material processing technology. This utility model discloses a feeding device for an extruder, including a base plate, an extruder body located on the left side of the top surface of the base plate, a discharge mechanism on the top surface of the base plate, a screening mechanism in the middle of the top surface of the base plate, and a pushing mechanism on the right side of the top surface of the base plate. This utility model uses a discharge wheel to evenly transport corn raw materials to the discharge port of the shell. When the second motor starts, its output end drives the first gear to rotate, which meshes with the second gear. The rotating shaft follows the second gear, driving the transmission rod to reciprocate. The reciprocating motion of the transmission rod causes the filter plate to reciprocate. At this time, the residue in the corn raw material, after being screened by the filter plate, falls directly into the collection box through the trough. Then, the pushing mechanism pushes the screened corn raw material into the interior of the extruder body for processing.
[0004] However, the above-mentioned technical solutions have the problem that the discharge mechanism is set too high, making it difficult for personnel to operate each time they need to add material. Sometimes, it is even necessary to use machinery to complete the operation of adding material into the discharge mechanism, which is time-consuming and labor-intensive and reduces processing efficiency. Therefore, this application proposes a feeding device for an extruder to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to solve the problems of the existing technology where the discharge mechanism is set too high, making it difficult for personnel to operate each time they need to add material, and sometimes even requiring the use of machinery to complete the operation of adding material into the discharge mechanism, which is time-consuming, labor-intensive, and reduces processing efficiency. Therefore, a feeding device for an extruder is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A feeding device for an extruder includes a base plate, on the top of which an extruder body is fixedly mounted. The top of the extruder body has a feed inlet. The feeding device also includes:
[0008] A sieve box is disposed above the feed inlet, and the left end of the sieve box is matched with the feed inlet;
[0009] A feed guide pipe, which is fixedly installed at the bottom of the screen box;
[0010] A vibration assembly is disposed on the top of the base plate and cooperates with the guide tube;
[0011] The feeding assembly includes: two support plates, a hopper, a discharge pipe, a bearing, two slide rods, and two electric push rods. The bottom ends of the two support plates are fixedly installed on the top of the base plate. The ends of the two slide rods that are far apart from each other are slidably connected to the sides of the two support plates that are close to each other. The ends of the two slide rods that are close to each other are fixedly installed on the outside of the bearing. The bearing is fixedly sleeved on the hopper. The bottom end of the discharge pipe is fixedly connected to the bottom of the hopper and cooperates with the screen box. The bottom ends of the two electric push rods are fixedly installed on the top of the base plate, and the output shafts of the electric push rods are fixedly installed on the bottom of the corresponding slide rods.
[0012] As a preferred embodiment of this utility model, each of the two support plates has a sliding groove on the side that is close to each other, and the ends of the two sliding rods that are far apart from each other are slidably connected in the two sliding grooves respectively.
[0013] As a preferred embodiment of this utility model, a second spring is fixedly installed on the top inner wall of each of the two slide grooves, and the bottom end of the second spring is fixedly installed on the top of the corresponding slide rod.
[0014] In a preferred embodiment of this utility model, a toothed ring is fixedly sleeved on the hopper, a drive motor is fixedly installed on the outside of the bearing, and a gear is fixedly installed on the output shaft of the drive motor, with the gear meshing with the toothed ring.
[0015] In a preferred embodiment of this utility model, the vibration assembly includes two U-shaped frames, four sliding shafts, four first springs, and two vibration motors. The two U-shaped frames are respectively fixedly installed on the front and rear sides of the guide tube. The bottom ends of the four sliding shafts are all fixedly installed on the top of the base plate. The top ends of the sliding shafts pass through the corresponding U-shaped frames and are slidably connected to the U-shaped frames. The first springs are sleeved on the corresponding sliding shafts. The top ends of the first springs are fixedly installed on the corresponding sliding shafts, and the bottom ends of the first springs are fixedly installed on the top of the corresponding U-shaped frames.

[0018] Beneficial effects:
[0019] 1. To solve the problem of difficult material feeding, two electric push rods can be activated to drive two sliding rods, bearings and hopper to move up and down. When the hopper moves down, it can lower the height of the hopper, making it easier for personnel to store materials inside the hopper, thereby reducing the difficulty of material feeding and improving processing efficiency.
[0020] 2. To facilitate the downward movement of the hopper, starting the drive motor can drive the gear to rotate. At this time, through the meshing transmission between the gear and the gear ring, the hopper and the discharge pipe can be rotated, thereby causing the discharge pipe to be misaligned with the screen box, so that the discharge pipe can move downward synchronously with the hopper;
[0021] 3. In order to achieve the vibration of the screen box, can the guide pipe and screen box be driven to vibrate by starting two vibration motors? Here, through the cooperation between the U-shaped frame, the sliding shaft and the first spring, the guide pipe and screen box can be stably elastically supported, ensuring the vibration stability of the guide pipe and screen box.
[0022] This utility model achieves height adjustment of the hopper through a simple structure, making it convenient for personnel to store materials inside the hopper, thereby reducing the difficulty of feeding, improving processing efficiency, and being easy to operate, saving time and effort, and highly practical.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example
[0030] Reference Figures 1-4 A feeding device for an extruder includes a base plate 1, an extruder body 2 fixedly mounted on the top of the base plate 1, and a feed inlet 3 opened on the top of the extruder body 2. The feeding device also includes:
[0031] Screen box 4 is positioned above feed inlet 3, and the left end of screen box 4 is matched with feed inlet 3.
[0032] The feed guide pipe 5 is fixedly installed at the bottom of the screen box 4;
[0033] The vibration assembly is located on the top of the base plate 1 and is in conjunction with the guide pipe 5.
[0034] The feeding assembly includes: two support plates 12, a hopper 13, a discharge pipe 14, a bearing 15, two slide rods 16, and two electric push rods 19. The bottom ends of the two support plates 12 are fixedly installed on the top of the base plate 1. The ends of the two slide rods 16 that are far apart from each other are slidably connected to the sides of the two support plates 12 that are close to each other. The ends of the two slide rods 16 that are close to each other are fixedly installed on the outside of the bearing 15. The bearing 15 is fixedly sleeved on the hopper 13. The bottom end of the discharge pipe 14 is fixedly connected to the bottom of the hopper 13. The bottom end of the discharge pipe 14 cooperates with the screen box 4. The bottom ends of the two electric push rods 19 are fixedly installed on the top of the base plate 1. The output shaft of the electric push rod 19 is fixedly installed on the bottom of the corresponding slide rod 16.
[0035] To solve the problem of difficulty in adding materials, such as Figure 3 As shown, by activating the two electric push rods 19, the two slide rods 16, the bearings 15 and the hopper 13 can be moved up and down. When the hopper 13 moves down, it can lower the height of the hopper 13, making it easier for personnel to store materials inside the hopper 13, thereby reducing the difficulty of feeding and improving processing efficiency.
[0036] In order to provide stable sliding support for the slide rod 16, bearing 15 and hopper 13, the two support plates 12 are provided with grooves 17 on the side that are close to each other, and the ends of the two slide rods 16 that are far apart from each other are slidably connected in the two grooves 17 respectively.
[0037] To assist the upward movement of the slide bar 16, bearing 15 and hopper 13, a second spring 18 is fixedly installed on the top inner wall of each of the two slide grooves 17, and the bottom end of the second spring 18 is fixedly installed on the top of the corresponding slide bar 16.
[0038] To facilitate the downward movement of the hopper 13, the drive motor 21 is started to drive the gear 22 to rotate. At this time, through the meshing transmission between the gear 22 and the gear ring 20, the hopper 13 and the discharge pipe 14 can be driven to rotate, thereby causing the discharge pipe 14 to be misaligned with the screen box 4, so that the discharge pipe 14 can move downward synchronously with the hopper 13. The gear ring 20 is fixedly sleeved on the hopper 13, and the drive motor 21 is fixedly installed on the outside of the bearing 15. The gear 22 is fixedly installed on the output shaft of the drive motor 21, and the gear 22 meshes with the gear ring 20.
[0039] To achieve vibration of the screen box 4, the two vibration motors 10 can drive the guide pipe 5 and the screen box 4 to vibrate. Here, the cooperation between the U-shaped frame 6, the sliding shaft 7 and the first spring 8 can provide stable elastic support for the guide pipe 5 and the screen box 4, ensuring the vibration stability of the guide pipe 5 and the screen box 4. The vibration assembly includes two U-shaped frames 6, four sliding shafts 7, four first springs 8 and two vibration motors 10. The two U-shaped frames 6 are respectively fixedly installed on the front and rear sides of the guide pipe 5. The bottom ends of the four sliding shafts 7 are all fixedly installed on the top of the base plate 1. The top ends of the sliding shafts 7 pass through the corresponding U-shaped frames 6 and are slidably connected to the U-shaped frames 6. The first spring 8 is sleeved on the corresponding sliding shaft 7. The top end of the first spring 8 is fixedly installed on the corresponding sliding shaft 7, and the bottom end of the first spring 8 is fixedly installed on the top of the corresponding U-shaped frame 6. The two vibration motors 10 are respectively fixedly installed on the front and rear sides of the guide pipe 5.
[0040] To improve the stability of the slide shaft 7, the same stabilizing rod 9 is fixedly installed on the two slide shafts 7 located on the same side.
[0041] In order to collect the screened impurities, a slag receiving box 11 is placed on the top of the bottom plate 1, and the bottom end of the feed pipe 5 is matched with the slag receiving box 11.
[0042] It should be noted that the specific models of vibration motor 10, electric push rod 19, and drive motor 21 used are to be selected by those skilled in the art. Furthermore, the vibration motor 10, electric push rod 19, and drive motor 21 mentioned above are all existing technologies and will not be elaborated upon in this solution.
[0043] The extruder body 2 adopts existing technology and can be directly used with the structure of the patent with application number 202320580156.6, so it will not be described in detail.
[0044] The working principle of this utility model is as follows: In use, first connect the extruder body 2, vibrating motor 10, electric push rod 19, and drive motor 21 to an external power source. Then, by activating the two electric push rods 19, the two sliding rods 16, bearings 15, and hopper 13 can be moved up and down. When the hopper 13 moves down, its height is lowered, making it easier for personnel to store materials inside, reducing the difficulty of feeding and improving processing efficiency. Activating the drive motor 21 drives the gear 22. When the material is rotated, the meshing transmission between the gear 22 and the gear ring 20 drives the hopper 13 and the discharge pipe 14 to rotate, thereby causing the discharge pipe 14 to be misaligned with the screen box 4 so that the discharge pipe 14 can move down synchronously with the hopper 13. In addition, by starting the two vibration motors 10, the guide pipe 5 and the screen box 4 can be driven to vibrate. Here, through the cooperation between the U-shaped frame 6, the sliding shaft 7 and the first spring 8, the guide pipe 5 and the screen box 4 can be stably elastically supported, ensuring the vibration stability of the guide pipe 5 and the screen box 4.
[0045] 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.
