[0001] This utility model relates to the technical field of quick-change structure for screens, specifically a quick-change structure for a polydextrose pulverizer screen. Background Technology
[0002] As an important piece of equipment for processing polydextrose materials, the polydextrose pulverizer plays a crucial role in food processing, pharmaceutical production, and other fields. Its screen component directly affects the particle size of the material and the quality of the finished product. In the existing technology, the screen replacement structure of the polydextrose pulverizer is mainly designed to realize the detachable and installable function of the screen on the equipment. Usually, by setting up connecting parts, fixing parts, and other structures, the screen is stably assembled in the pulverizer's pulverizing chamber or corresponding position. When it is necessary to adjust the particle size of the material or to clean or maintain the screen, the screen can be replaced according to specific operating procedures to adapt to different production needs and ensure the normal operation of the pulverizing operation.
[0003] Currently, traditional devices are cumbersome to replace screens, requiring the removal of multiple fasteners, the use of special tools, and careful adjustment of the position. This forces workers to spend a lot of time and effort on the operation, which not only increases the complexity of the operation but also significantly reduces the overall work efficiency and affects the continuity of the production process. To address this, we propose a quick screen replacement structure for polydextrose pulverizers. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-change structure for a polydextrose pulverizer screen, comprising a housing and a pulverizing frame; the bottom of the pulverizing frame is fixed to the top of the housing, and a drive motor providing power is installed on one side of the pulverizing frame; a transmission rod is fixedly installed at the output end of the drive motor; one end of the transmission rod passes through the interior of the pulverizing frame and is rotatably connected thereto; a quick-change mechanism is installed inside the pulverizing frame; a pulverizing cover plate is installed on the opposite side of the pulverizing frame; and a conveying port is opened on the outer surface of the pulverizing cover plate; the pulverizing frame and the pulverizing cover plate are hinged to each other.
[0006] Among them, a feeding frame is installed on the side of the crushing cover away from the crushing frame, and the discharge port of the feeding frame is in contact with the conveying port on the outer surface of the crushing cover.
[0007] One end of the transmission rod is fixedly installed with a rotating disk, and the outer surface of the rotating disk rotates relative to the inner wall of the crushing frame. The outer surface of the rotating disk has an arc-shaped groove, and a limit groove is provided below the arc-shaped groove. The limit grooves are evenly distributed on the outer surface of the rotating disk.
[0008] The quick-change component includes a connecting ring and a screen for screening. The connecting ring and the screen are fixed to each other, and one end of the connecting ring is engaged inside the arc-shaped groove.
[0009] The inner wall of the connecting ring is fixedly equipped with a snap-fit block, and the outer surface of the snap-fit block is in contact with the inner wall of the limiting groove. The screen is equipped with a limiting plate inside. The side of the limiting plate near the transmission rod is in contact with the rotating plate and the side of the snap-fit block. Multiple crushing rods are installed on the outer surface of the limiting plate.
[0010] The center of the limiting plate is equipped with a rotating block, one end of which passes through the interior of the rotating plate and the transmission rod and is threadedly connected to the rotating plate and the transmission rod.

The pulverizing frame 2 and the pulverizing cover plate 6 are hinged to each other. Through the setting of the drive motor 3, the transmission rod 4 can be driven to rotate by its own output end.
[0017] A feeding frame 7 is installed on the side of the crushing cover plate 6 away from the crushing frame 2, and the discharge port of the feeding frame 7 is in contact with the conveying port on the outer surface of the crushing cover plate 6. Through the setting of the feeding frame 7 and the output port, the polydextrose raw material can be quickly and stably conveyed into the interior of the crushing frame 2, which facilitates the subsequent crushing work.
[0018] A rotating disk 8 is fixedly installed at one end of the transmission rod 4, and the outer surface of the rotating disk 8 rotates relative to the inner wall of the crushing frame 2. An arc-shaped groove 81 is opened on the outer surface of the rotating disk 8, and a limiting groove 82 is set below the arc-shaped groove 81. The limiting groove 82 is evenly distributed on the outer surface of the rotating disk 8. By setting the rotating disk 8, the position of the connecting ring 51 can be limited by the arc-shaped groove 81 and the limiting groove 82, and the limiting disk 54 can drive the screen 52 and the crushing rod 541 to rotate.
[0019] The quick-change assembly includes a connecting ring 51 and a sieve 52 for screening. The connecting ring 51 and the sieve 52 are fixed to each other, and one end of the connecting ring 51 is engaged inside the arc groove 81. Through the setting of the sieve 52, the crushed glucose can be effectively transported from the inside of the crushing frame 2 to the inside of the conveying frame 9, and the conveying frame 9 carries the raw material into the sugar powder collection frame 10, thereby completing the subsequent collection.
[0020] A snap-fit block 53 is fixedly installed on the inner wall of the connecting ring 51, and the outer surface of the snap-fit block 53 is in contact with the inner wall of the limiting groove 82. A limiting disk 54 is installed inside the screen 52. The side of the limiting disk 54 near the transmission rod 4 is in contact with the side of the rotating disk 8 and the snap-fit block 53. Multiple sets of crushing rods 541 are installed on the outer surface of the limiting disk 54. Through the setting of the snap-fit block 53 and the connecting ring 51, the screen 52 can be installed on one side of the rotating disk 8 and its position can be restricted to a certain extent.
[0021] A rotating block 55 is installed at the center of the limiting plate 54, and one end of the rotating block 55 passes through the interior of the rotating plate 8 and the transmission rod 4 and is threadedly connected to the rotating plate 8 and the transmission rod 4. The screen 52, the crushing rod 541 and the limiting plate 54 are all located inside the crushing frame 2. By setting the rotating block 55, the limiting plate 54 can be firmly installed on one side of the rotating plate 8 by its own rotation, and the positions of the connecting ring 51 and the screen 52 are fixed.
[0022] A conveying frame 9 is fixedly installed on the inner wall of the crushing frame 2, and a sugar powder collection frame 10 is installed below the conveying frame 9. The outer surface of the sugar powder collection frame 10 is fixedly connected to the inner wall of the box body 1, and a discharge frame 11 is installed inside the sugar powder collection frame 10. The discharge frame 11 extends to the outside of the box body 1. Through the setting of the sugar powder collection frame 10, the crushed sugar powder can be effectively discharged and it is convenient for staff to collect.
[0023] In use, firstly, the polydextrose raw material to be crushed is poured into the feeding frame 7. The raw material enters the crushing frame 2 through the discharge port of the feeding frame 7 and the conveying port on the crushing cover plate 6, falling onto the upper surface of the screen 52. The drive motor 3 is started, and its output end drives the rotating disk 8 to rotate on the inner wall of the crushing frame 2 through the transmission rod 4. Since the locking block 53 of the connecting ring 51 is locked in the limiting groove 82 of the rotating disk 8, the rotation of the rotating disk 8 is transmitted to the connecting ring 51 through the locking block 53, thereby driving the screen 52 to rotate synchronously. At the same time, the limiting disk 54 is threadedly connected to the transmission rod 4 through the central rotating block 55. The rotation of the transmission rod 4 also drives the limiting disk 54 and the multiple sets of crushing rods 541 fixed on its outer surface to rotate at high speed. At this time, the screen 52 rotates with the rotating disk 8, while the crushing rods 541 make circular motion inside the screen 52. The relative motion of the two impacts and grinds the raw material on the screen 52, realizing the crushing process of polydextrose. The crushed sugar powder particles fall into the conveying frame 9 below through the screen holes of the screen 52, are guided by the conveying frame 9 to the sugar powder collection frame 10, and finally discharged through the discharge frame 11 extending to the outside of the box 1, completing the crushing operation. When it is necessary to replace the screen 52, first turn off the power supply. Drive motor 3 and open crushing cover 6. Rotate the rotating block 55 at the center of limit disk 54 clockwise to loosen the threaded connection between rotating block 55 and transmission rod 4. Then remove limit disk 54 from crushing frame 2. At this time, connecting ring 51 loses the side contact of limit disk 54. Simply pull connecting ring 51 outward along arc groove 81 to remove connecting ring 51 and screen 52 fixed on it together, completing the disassembly of old screen 52. When installing new screen 52, align the connecting ring 51 of new screen 52 with arc groove 81 on rotating disk 8 and insert it, so that the inner wall of connecting ring 51 is engaged. Block 53 is fully inserted into the limiting groove 82 of the rotating disk 8, ensuring that the relative position of the connecting ring 51 and the rotating disk 8 is fixed. Next, the limiting disk 54 is placed inside the screen 52, so that the side of the limiting disk 54 near the transmission rod 4 is tightly fitted with the side of the rotating disk 8 and the locking block 53. Then, the rotating block 55 is rotated counterclockwise to tighten the threaded connection between the rotating block 55 and the transmission rod 4, thereby stably fixing the limiting disk 54, the connecting ring 51 and the screen 52 in the crushing frame 2. Finally, the crushing cover 6 is closed, and the drive motor 3 can be restarted to carry out the crushing operation. At this point, the overall operation process is completed.
