Abstract
Description
Technical Field
[0001] This utility model relates to the field of amino molding compound production technology, and in particular to a granulator transmission device for amino molding compound production. Background Technology
[0002] In the production of amino molding compounds, the stable operation of the granulator transmission device is crucial. Existing transmission devices rely on lubricating oil to ensure the lubrication of gears and bearings. However, during long-term operation, metal shavings from transmission components, externally infiltrated dust, and gum deposits generated by the oxidation of the lubricating oil itself mix in the oil, forming contaminants. These contaminants accelerate the wear of transmission components, reduce the lubricating and heat dissipation performance of the lubricating oil, and severely affect the service life and reliability of the transmission device. To address this problem, some equipment has been equipped with independent external oil filtration systems. However, this not only increases additional manufacturing costs and energy consumption, but also makes the filters more prone to clogging, requiring frequent shutdowns for cleaning or replacement, resulting in inconvenient maintenance and interruptions to production continuity. Therefore, this paper proposes a new granulator transmission device for the production of amino molding compounds. Utility Model Content
[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A granulator transmission device for the production of amino molding compounds includes a screw extruder granulator. A bracket, fixedly connected to the main body of the screw extruder granulator, is fixedly connected to the outer side of the drive motor. A crankshaft is fixedly connected to the end of the main shaft of the drive motor, and the other end of the crankshaft is fixedly connected to the gearbox drive shaft of the drive motor. A push-pull rod is rotatably connected to one end of the crankshaft, and a piston plate is rotatably connected to the other end of the push-pull rod via a rotating shaft. A piston box, fixedly connected to the bracket, is slidably limited on the outer side of the piston plate. An oil extraction pipe is connected to the rear end of the bottom right side of the piston box, and an oil outlet pipe is connected to the center of the bottom right side of the piston box. A filter cylinder and a fixed sleeve, arranged internally and externally, are fixedly connected to the outer side of the other end of the oil outlet pipe. The filter cylinder is fixedly connected to the bracket, and the filter cylinder is fixedly connected to the fixed sleeve. A return pipe is connected to the bottom right side of the fixed sleeve.
[0006] As a further improvement of this utility model, a one-way valve is provided on the inner side of the oil extraction pipe and the inner side of the oil outlet pipe, and the other end of the oil extraction pipe and the other end of the return pipe are connected to the gearbox oil sump of the screw extrusion granulator drive motor.
[0007] As a further improvement of this utility model, a scraper is in contact with one end of the inner side of the filter cylinder, and a fixed shaft is fixedly connected to the outer side of the scraper through the fixed sleeve, and the fixed shaft is rotatably connected to the fixed sleeve.
[0008] As a further improvement of this utility model, a fixed cover is rotatably connected to the top of the outer side of the fixed shaft, and the crankshaft passes through the fixed cover. The crankshaft is rotatably connected to the fixed cover. A driven bevel gear is fixedly connected to the top of the fixed shaft, and a driving bevel gear fixedly connected to the crankshaft is meshed on the outer side of the driven bevel gear.
[0009] As a further improvement of this utility model, a conical cover is fixedly connected to the bottom inner side of the fixed sleeve, and a conveying pipe that penetrates the support is connected to the bottom end of the conical cover. A valve is installed inside the conveying pipe, and a transparent glass collection bottle is spirally connected to the bottom outer side of the conveying pipe.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] By utilizing the drive motor of the screw extruder granulator as a power source, the lubricating oil in the drive motor gearbox is simultaneously extracted for filtration and the filter cartridge for cleaning is scraped and cleaned at the same time as granulation starts. This achieves real-time online filtration of gearbox lubricating oil and self-cleaning of the filter cartridge without additional power, overcoming the problems of high energy consumption and complex structure of traditional independent oil filtration systems. It can effectively remove oil impurities, significantly reduce wear on transmission components, and extend the service life of the equipment. Since the filtered material can be cleaned simply by removing the collection bottle, it also avoids the disadvantage of needing to stop the machine for maintenance due to filter cartridge blockage, greatly reducing maintenance costs and ensuring the continuity and stability of the production process.

[0018] Example 1
[0019] like Figure 1-3 As shown, a granulator transmission device for the production of amino molding compounds includes a screw extruder granulator 1. A bracket 2, which is fixedly connected to the outside of the drive motor of the screw extruder granulator 1 and fixedly connected to the body of the screw extruder granulator 1, is fixedly connected to the end of the main shaft of the drive motor of the screw extruder granulator 1. The other end of the crankshaft 3 is fixedly connected to the gearbox drive shaft of the drive motor of the screw extruder granulator 1. A push-pull rod 4 is rotatably connected to one end of the crankshaft 3. A piston plate 5 is rotatably connected to the other end of the push-pull rod 4 via a rotating shaft. A piston box 6, which is fixedly connected to the bracket 2, is limited and slidably connected to the outside of the piston plate 5. An oil extraction pipe 7 is connected to the rear end of the bottom right side of the piston box 6. An oil outlet pipe 8 is connected to the center of the bottom right side of the piston box 6. A filter cylinder 10 and a fixing sleeve 9, which are arranged inside and outside, are fixedly connected to the other end of the oil outlet pipe 8. The filter cylinder 10 is fixedly connected to the bracket 2 and the fixing sleeve 9. A return pipe 11 is connected to the bottom right side of the fixing sleeve 9.
[0020] Furthermore, such as Figure 1-3As shown, one-way valves are provided on the inner side of the oil extraction pipe 7 and the inner side of the oil outlet pipe 8. The other end of the oil extraction pipe 7 and the other end of the return pipe 11 are connected to the gearbox oil sump of the screw extruder granulator 1 drive motor. By providing one-way valves on the inner side of the oil extraction pipe 7 and the inner side of the oil outlet pipe 8, the normal extraction and return of lubricating oil in the gearbox of the screw extruder granulator 1 drive motor is ensured, forming a complete, closed, unidirectional flow circulation loop, effectively preventing oil backflow and ensuring filtration efficiency.
[0021] Furthermore, such as Figure 1 and Figure 3 As shown, a scraper 12 is in contact with one end of the inner side of the filter cylinder 10. A fixed shaft 13 that passes through the fixed sleeve 9 is fixedly connected to the outer side of the scraper 12. The fixed shaft 13 is rotatably connected to the fixed sleeve 9. The scraper 12 is driven by the fixed shaft 13 to scrape the inner wall of the filter cylinder 10, which can always keep the pores of the filter cylinder 10 unobstructed, so that the flow rate and efficiency of the filtration system remain stable throughout the entire operating cycle, and ensure that the cleanliness of the lubricating oil is always at a high level.
[0022] Furthermore, such as Figure 1 and Figure 3 As shown, a fixed cover 14 is rotatably connected to the outer top of the fixed shaft 13, and the crankshaft 3 passes through the fixed cover 14. The crankshaft 3 is rotatably connected to the fixed cover 14. A driven bevel gear 15 is fixedly connected to the top of the fixed shaft 13. A driving bevel gear 16, which is fixedly connected to the crankshaft 3, is meshed with the outer side of the driven bevel gear 15. By utilizing the driving bevel gear 16 and the driven bevel gear 15, the horizontal rotational motion of the crankshaft 3 is efficiently converted into the vertical rotational motion of the fixed shaft 13, which facilitates the driving of the scraper 12 for cleaning the filter cartridge 10.
[0023] Furthermore, such as Figure 1 and Figure 3 As shown, a conical cover 17 is fixedly connected to the bottom inner side of the fixed sleeve 9. The bottom end of the conical cover 17 is connected to a conveying pipe 18 that passes through the bracket 2. A valve is installed inside the conveying pipe 18. A transparent glass collection bottle 19 is spirally connected to the bottom outer side of the conveying pipe 18. Oil impurities scraped off fall into the collection bottle 19 through the conical cover 17 and the conveying pipe 18. After manually closing the valve inside the conveying pipe 18 and rotating the collection bottle 19 to disengage it from the conveying pipe 18, it is convenient to process oil impurities without stopping the machine. After processing the oil impurities, simply fill the collection bottle 19 with lubricating oil, then reset the collection bottle 19 and open the valve of the conveying pipe 18.
[0024] The principle of gearbox lubricating oil filtration and cleaning in transmission components: The drive motor spindle of the screw extruder granulator 1 drives the crankshaft 3 to rotate. The crankshaft 3 reciprocates by pushing and pulling the push rod 4, which in turn pushes and pulls the piston plate 5 to reciprocate within the piston box 6. This draws dirty oil from the gearbox through the oil extraction pipe 7 and forces it into the filter cylinder 10 through the oil outlet pipe 8. The oil is purified as it passes through the filter screen of the filter cylinder 10. The clean lubricating oil then flows into the fixed sleeve 9 and returns to the gearbox through the return pipe 11, forming a continuous online filtration cycle. At the same time, the crankshaft 3 also drives the drive bevel gear 1. 6. The driven bevel gear 15 engages, which in turn drives the fixed shaft 13 to rotate, causing the scraper 12 on the outside of the fixed shaft 13 to continuously scrape off the oil impurities adhering to the inner wall of the filter cartridge 10. The scraped-off oil impurities are finally collected through the conical cover 17 and fall into the detachable collection bottle 19 through the conveying pipe 18. When cleaning is required, simply close the valve on the conveying pipe 18 and unscrew the collection bottle 19 to achieve maintenance without stopping the machine. After processing, simply fill the collection bottle 19 with lubricating oil, then put the collection bottle 19 back in and open the valve, and the system will continue to run.
