Description

Technical Field

[0001] This application relates to the field of granulator technology, and in particular to a scraping mechanism for a granulator. Background Technology

[0002] Currently, granulators are devices that process powders, molten materials, or wet materials into particles of specific shapes and sizes, and are widely used in chemical, pharmaceutical, food, agricultural, and environmental protection fields. Their working principles are diverse, including dry (roller crushing), wet (drying after mixing with binder), melt (extrusion cooling), spray (atomization drying), and rotary (rolling into spheres) granulation methods, ultimately forming uniform particles for easy transportation, storage, or subsequent processing. Granulators not only improve material flowability and density but also reduce dust pollution, making them a key forming equipment in industrial production.

[0003] During granulation, the granules are formed on the granulator's conveyor belt and transported along with it. In operation, a scraper is installed on one side of the conveyor belt, pressed against the belt. As the conveyor belt passes the scraper, it scrapes the granules off the belt. For the scraper to effectively remove the granules, it must be pressed firmly against the conveyor belt.

[0004] Regarding the aforementioned technologies, the inventors believe that after a period of continuous operation, the end of the scraper will wear down. If the worn scraper is not replaced in time, it will affect the processing of materials. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a scraping mechanism for a granulator, which solves the problem that the end of the scraper will wear after the scraper has been working continuously for a period of time, and if the worn scraper is not replaced in time, it will affect the material processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A scraping mechanism for a granulator includes: a frame for supporting the scraping mechanism; a scraper mounted on the frame for scraping granules off a conveyor belt; and a pressing assembly mounted on the frame for pressing the scraper against the conveyor belt.

[0008] Furthermore, the pressing assembly includes a vertical clamp mounted on the frame, and a pressure bar is formed on one side of the vertical clamp, the pressure bar facing the scraper.

[0009] Furthermore, an adjusting rod is provided on one side of the pressure rod, and a screw is provided at one end of the adjusting rod. One end of the screw passes through the adjusting rod, and the screw is threadedly connected to the adjusting rod.

[0010] Furthermore, the adjusting rod is provided with an extension rod, one end of which slides with the adjusting rod, and the other end extends toward the side closer to the scraper.

[0011] Furthermore, a support spring is provided at one end of the extension rod near the adjusting rod, and the two ends of the support spring are respectively pressed against the extension rod and the adjusting rod.

[0012] Furthermore, a pressure head is provided at one end of the extension rod near the scraper, and the pressure head abuts against the scraper on the side near the conveyor belt.

[0013] Furthermore, the scraper is provided with a connecting bolt, one end of which passes through the scraper and the frame, and a nut is provided at the end of the connecting bolt that passes through the frame. The nut is threaded onto the connecting bolt. A rubber pad is provided between the scraper and the frame, and the rubber pad is pressed against the scraper and the frame.

[0014] In summary, this application includes at least one of the following beneficial technical effects of the scraping mechanism for a granulator:

[0015] 1. When in use, install the scraper on the frame, press the component to press the scraper against the conveyor belt, and the scraper scrapes the material off the conveyor belt. After the scraper has been working for a period of time, if the end of the scraper is worn, the pressing component will press the scraper against the conveyor belt, so that the operator does not need to replace the worn scraper in time, thus improving the material processing efficiency.

[0016] 2. By setting a vertical clamp on the adjusting rod, the boundary line where the scraper is pressed can be raised;

[0017] 3. The pressure head at one end of the extension rod and the rubber pad between the scraper and the frame improve the stability of the scraper pressing against the conveyor belt. Attached Figure Description

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a scraping mechanism for a granulator.

[0025] Reference Figure 1 A scraping mechanism for a granulator includes a frame 1, on which a scraper 2 is mounted for scraping granules off a conveyor belt. A pressing assembly 3 is mounted on the frame 1 for pressing the scraper 2 against the conveyor belt.

[0026] Three sets of pressing components 3 are spaced apart on the frame 1, and the three sets of pressing components 3 press the scraper 2 against the conveyor belt. Furthermore, the scraper 2 is spaced apart in three sets, and the three sets of pressing components 3 press the scraper 2 against the conveyor belt respectively. This improves the ease with which the scraper 2 is pressed against the conveyor belt.

[0027] Reference Figure 2 The pressing assembly 3 includes a vertical clamp 31, which is mounted on the frame 1. A pressure bar 32 is provided on the vertical clamp 31. In use, the vertical clamp 31 drives the pressure bar 32 to move towards or away from the scraper 2.

[0028] To further improve the stability of the pressure rod 32 pressing against the scraper 2, an adjusting rod 33 is provided on the pressure rod 32. A screw 34 is provided at one end of the adjusting rod 33. One end of the screw 34 is connected to the adjusting rod 33, and the other end passes through the pressure rod 32, and the screw 34 is threadedly connected to the pressure rod 32. In use, rotating the screw 34 is used to control the distance between the adjusting rod 33 and the scraper 2.

[0029] Furthermore, an extension rod 35 is provided on the side of the adjusting rod 33 near the scraper 2. One end of the extension rod 35 slides with the adjusting rod 33, and the other end extends towards the scraper 2. A support spring 36 is provided between the extension rod 35 and the adjusting rod 33, and the support spring 36 abuts against the extension rod 35 and the adjusting rod 33. In use, the support spring 36 presses one end of the extension rod 35 against the scraper 2. Since one end of the extension rod 35 is pressed against the scraper 2, when the adjusting rod 33 rotates towards the scraper 2, the support spring 36 between the adjusting rod 33 and the extension rod 35 is compressed. At this time, the scraper 2 is further pressed against the conveyor belt. When the adjusting rod rotates away from the scraper 2, the support spring 36 between the adjusting rod 33 and the extension rod 35 unfolds. At this time, the scraper 2 moves away from the conveyor belt.

[0030] In order to reduce the rigid connection between the extension rod 35 and the scraper 2, a pressure head 37 is provided at one end of the extension rod 35 near the scraper 2. The pressure head 37 is made of rubber and is pressed against the scraper 2 during use.

[0031] Reference Figure 3 To improve the stability of the scraper 2 on the frame 1, a connecting bolt 21 is provided on the scraper 2. One end of the connecting bolt 21 passes through the scraper 2 and the frame 1, and a nut 22 is provided on the end of the connecting bolt 21 that passes through the frame 1. The nut 22 is threaded onto the connecting bolt 21, and one end of the nut 22 is pressed against the scraper 2. Furthermore, a rubber pad 11 is provided between the scraper 2 and the frame 1. The rubber pad 11 supports the scraper 2. When the pressure head 37 presses against the scraper 2, the rubber pad 11 is compressed. Due to the supporting effect of the rubber pad 11, the scraper 2 is prevented from pressing excessively against the conveyor belt.

[0032] Furthermore, because the scraper 2 is designed in sections, when one section becomes excessively worn, only one section needs to be replaced, rather than the entire scraper 2.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
