[0002] A granulator is a molding machine that shapes materials into specific forms. Its main function is to process raw materials into granules or spheres through specific processes for easy storage, transportation, and use. During the use of a granulator, in order to ensure that the raw materials enter the equipment evenly, they are generally poured into a feeding hopper for uniform feeding.

[0003] However, since the raw materials are generally in powder or fine form, they are prone to clumping together due to moisture in the air after being poured into the feeding hopper, which can cause blockage at the discharge port at the bottom of the feeding hopper and affect its normal discharge.

[0004] Therefore, it is necessary to provide a new pellet mill feeding device that avoids clogging to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the granulator feeding device for preventing clogging provided by this utility model; Figure 2 This is a schematic diagram of the feed hopper structure from an oblique upward view in this utility model; Figure 3 This is an assembly diagram of the sealing pipe, connecting arm, and scraper in this utility model; Figure 4 This is a schematic diagram of the assembly of the toothed column and the toothed wheel in this utility model; Figure 5 This is a cross-sectional view of the sealed pipe and the open pipe in this utility model. Figure 6This is a schematic diagram of the connection structure of the connecting sleeve and scraper in this utility model. The granulator feeding device to prevent clogging includes: a feeding hopper 1 with a discharge port 2 at its bottom; a mounting platform 3 is bolted to the outer wall of the feeding hopper 1 for easy removal of the platform 3 from the hopper 1; two guide rods 4 are slidably mounted on the mounting platform 3; a connecting plate 5 is fixedly mounted on the top of the two guide rods 4; a sealing pipe 6 is fixedly mounted on the connecting plate 5; and a reduction motor is fixedly mounted on the top of the connecting plate 5. Complete gears are fixedly fitted onto both the output shaft of the reduction motor and the sealing pipe 6. The two complete gears mesh, and the reduction motor drives the sealing pipe 6 to rotate. The bottom end of the sealing pipe 6 extends into the feeding hopper 1 and has an opening pipe 8 fixedly mounted thereon. The bottom end of the opening pipe 8 passes through the discharge port 2 and extends to the bottom of the feeding hopper 1. A vent is provided at the bottom of the sealing pipe 6. The vent is connected to the open pipe 8. Multiple first hollow stirring rods 7 are fixedly installed on the sealing pipe 6, and the first hollow stirring rods 7 are connected to the interior of the sealing pipe 6. Multiple second hollow stirring rods 9 are fixedly installed on the open pipe 8, and the second hollow stirring rods 9 are connected to the interior of the open pipe 8. The multiple first hollow stirring rods 7 and multiple second hollow stirring rods 9 are all in an inclined state, which has a good stirring effect. A hot air fan 19 is fixedly installed on the top of the mounting platform 3. One end of the air supply pipe 20 is fixedly installed on its air outlet. The other end of the air supply pipe 20 extends into the sealing pipe 6 and slides to connect with the top of the sealing pipe 6. In this way, hot air can be delivered to the sealing pipe 6, the open pipe 8, the first hollow stirring rods 7 and the second hollow stirring rods 9, thereby enabling the raw materials in the feeding hopper 1 to be dried and dispersed.

[0023] In the above method, in order to scrape off some raw materials adhering to the inner wall of the feeding hopper 1, two scraper blades 12 are provided in the feeding hopper 1. Both scraper blades 12 are in contact with the inner wall of the feeding hopper 1. Two connecting arms 10 are fixedly installed on the sealing pipe 6. Connecting sleeves 11 are slidably sleeved on both connecting arms 10. The two connecting sleeves 11 are fixedly connected to the two scraper blades 12 on their respective opposite sides. Studs 13 are threaded on both connecting sleeves 11. The bottom ends of the two studs 13 abut against the two connecting arms 10 respectively. When the scraper blades 12 wear down and no longer contact the inner wall of the feeding hopper 1, the position of the connecting sleeves 11 on the connecting arms 10 can be adjusted accordingly.

[0024] In this method, in order to enable the first hollow agitator 7 and the second hollow agitator 9 to move up and down within the feeding hopper 1 to enhance the unblocking function of raw materials, a return spring 14 is fitted on each of the two guide slide rods 4. The top end of the return spring 14 is fixedly connected to the connecting plate 5, and its bottom end is fixedly connected to the mounting platform 3. The bottom ends of the two guide slide rods 4 are fixedly installed with the same horizontal connecting strip 15. The top of the horizontal connecting strip 15 is fixedly installed with a toothed column 16. The bottom of the mounting platform 3 is fixedly installed with a servo motor 17. The output shaft of the servo motor 17 is fixedly fitted with a toothed gear 18. The toothed gear 18 is adapted to the toothed column 16. By utilizing the intermittent meshing of the teeth of the toothed gear 18 and the teeth of the toothed column 16, the first hollow agitator 7 and the second hollow agitator 9 can reciprocate up and down, thereby improving the unblocking effect.

[0025] In this method, in order to install the feed hopper 1 at a designated position on the granulator, two connecting columns 21 are fixedly installed at the bottom of the feed hopper 1. The same mounting base 22 is fixedly installed at the bottom of the two connecting columns 21, and the mounting base 22 has a feeding port.

[0026] The working principle of the clogging-avoiding pellet mill feeding device provided by this utility model is as follows:

[0027] In this device, the feeding hopper 1 is first installed above the feed inlet of the granulator via the mounting chassis 22, so that the discharge port 2 corresponds to the feed inlet of the granulator.

[0028] When raw materials need to be fed into the granulator, a large amount of raw materials is first poured into the feeding hopper 1. During the pouring process, some raw materials will enter the granulator. To ensure uniform feeding, the reduction motor can be started. Through the meshing of two complete gears, the sealing pipe 6 rotates together with the opening pipe 8. Then, the hot air fan 19 is started. The hot air generated by the hot air fan 19 is sent into the sealing pipe 6 through the air supply pipe 20, and then into the opening pipe 8 through the vent. In this way, the hot air is sent into multiple first hollow stirring rods 7 and multiple second hollow stirring rods 9, so that the raw materials in contact with them can be heated, thereby achieving the purpose of drying. The opening pipe... The opening at the bottom of channel 8 allows the incoming hot air to be continuously discharged to ensure normal airflow. Then, the servo motor 17 is started, and its output shaft drives the toothed gear 18 to rotate. When its teeth contact the teeth on the toothed column 16, it will lift the toothed column 16, thereby lifting the connecting plate 5 and the sealing pipe 6. At this time, the return spring 14 is also gradually stretched. When the teeth of the two separate, the stretched return spring 14 immediately pulls back, causing the sealing pipe 6 to quickly descend to its original position. When the teeth of the two mesh again, it will rise again. After that, when the teeth separate again, it will descend again. This process repeats, causing the sealing pipe 6 and the opening pipe 8 to move up and down continuously.

[0029] Thus, driven by the sealing pipe 6 and the opening pipe 8, multiple first hollow stirring rods 7, multiple second hollow stirring rods 9, and two scrapers 12 can reciprocate up and down during rotation, thereby drying and breaking up some clumps of raw materials. At the same time, some materials adhering to the inside of the feeding hopper 1 can also be scraped off by the rotation of the scrapers 12, so that they can be evenly discharged from the discharge port 2, achieving uniform feeding.

[0030] Compared with related technologies, the clogging-avoiding pellet mill feeding device provided by this utility model has the following beneficial effects:

[0031] This utility model provides a granulator feeding device to avoid blockage. By setting a first hollow stirring rod 7 and a second hollow stirring rod 9 on the sealing pipe 6 and the opening pipe 8 respectively, and by using a hot air blower 19 to send hot air into the first hollow stirring rod 7 and the second hollow stirring rod 9, the raw materials can be dried and dispersed. At the same time, through the intermittent meshing between the toothed wheel 18 and the toothed column 16, the sealing pipe 6 and the opening pipe 8 can move up and down, thereby ensuring that the raw materials can be discharged evenly through the discharge port 2.
