Description

Technical Field

[0001] This utility model relates to the field of sand mixing machine technology, and in particular to a sand mixing machine for preparing resin sand from quartz sand and resin. Background Technology

[0002] A quartz sand and resin sand mixer is a device used to uniformly mix resin binders with sand particles. In processes such as casting, it enables the resin to evenly coat the surface of the sand particles, forming molding sand with specific properties, which is used to manufacture sand molds. This molding sand has advantages such as high strength and good permeability, playing a crucial role in improving the quality and precision of castings.

[0003] Existing resin sand mixers typically achieve mixing through a stirring device. First, the materials for preparing resin sand are added to a mixing tank. Driven by a motor, the stirrer rotates at high speed, causing the sand particles to continuously tumble and collide within the tank, thereby preparing the resin sand.

[0004] While existing resin sand mixers achieve the mixing of raw materials, the adhesive nature of resin sand makes it easy for it to adhere to the inner walls and mixing blades of the mixer during the mixing process. Furthermore, existing sand mixers are inconvenient to clean, making cleaning difficult and hindering effective cleaning of the mixing drum. Over time, this accumulation not only affects the quality of the mixed sand but also causes corrosion and wear on the equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sand mixer for preparing resin sand from quartz sand and resin, aiming to improve the problem of effective cleaning of existing sand mixers.

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

[0010] As a further description of the above technical solution:

[0011] The stirring assembly includes a stirring roller one, a stirring roller two rotatably connected to the middle of the bucket lid, a middle of the bucket lid rotatably connected to the outer periphery of the stirring roller one, and a gear one and a gear three fixedly connected to the outer periphery of the stirring roller one and the stirring roller two, respectively, and the gear one and the gear three meshing with the gear two.

[0012] As a further description of the above technical solution:

[0013] A second fixing block is fixedly connected to the outer periphery of the sand mixing bucket, and a support column is fixedly connected to the bottom of the second fixing block.

[0014] As a further description of the above technical solution:

[0015] The bottom of the sand mixing bucket is fixedly connected to a sand outlet pipe, and a valve is fixedly connected to the middle of the sand outlet pipe.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when it is necessary to clean the sand mixer, water and acetone are injected into the bucket through the feed inlet and liquid inlet pipe, respectively. Then, the drive motor works, which drives the connecting rod, scraper and mixing roller to rotate simultaneously under the action of gears, thereby scraping the inner wall of the sand mixing bucket. After cleaning, the water will be discharged through the sand outlet pipe, thus realizing the cleaning of the sand mixer. This makes it convenient for workers to clean the sand mixer and greatly improves the cleaning effect.

A gear 2 9 is fixedly connected to the outer periphery of the connecting rod 21. When the motor 10 is working, it drives the connecting rod 21 to rotate, thereby driving the gear 2 9 to rotate accordingly. A scraper 20 is fixedly connected to one end of the connecting rod 21. A brush 22 is fixedly connected to the side of the scraper 20. When the connecting rod 21 rotates, it drives the scraper 20 and the brush 22 to rotate simultaneously, thereby scraping the inner wall and bottom of the mixing bucket 1 to complete the cleaning of the mixing bucket 1. A feed inlet 3 is fixedly connected to the top of the bucket cover 2.

[0034] Reference Figure 1 , Figure 4 and Figure 5The disassembly assembly includes a pull rod 5, the outer periphery of which is slidably connected to the inside of the mixing bucket 1, allowing the pull rod 5 to slide inside the mixing bucket 1. A locking block 24 is fixedly connected to one end of the pull rod 5, and a spring 23 is fixedly connected to the side of the locking block 24. When the pull rod 5 is pulled, the locking block 24 compresses the spring 23; when the pull rod 5 is released, the tension of the spring 23 ejects the locking block 24. One end of the spring 23 is fixedly connected to the mixing bucket 1. A slot 25 is provided inside the bucket cover 2, and the locking block 24 engages with the slot 25, thereby enabling the disassembly of the bucket cover 2 for easy maintenance of the mixing assembly and improved work efficiency. The mixing assembly includes a first mixing roller 8, and a second mixing roller 13 is rotatably connected to the middle of the bucket cover 2. The first mixing roller 8 is rotatably connected to the middle of the bucket cover 2, allowing both the first mixing roller 8 and the second mixing roller 13 to rotate within the middle of the bucket cover 2. Gears 7 are fixedly connected to the outer periphery of both the first mixing roller 8 and the second mixing roller 13. Gear 14 and gear 7 are meshed with gear 9. When gear 9 rotates, it drives gear 7 and gear 14 to rotate simultaneously, thereby driving stirring roller 8 and stirring roller 2 to rotate, so as to mix the raw materials. A fixing block 2 15 is fixedly connected to the outer periphery of the sand mixing tank 1. A support column 19 is fixedly connected to the bottom of the fixing block 2 15 to fix the sand mixing tank 1 for better operation. A sand outlet pipe 16 is fixedly connected to the bottom of the sand mixing tank 1 to discharge the mixed sand and discharge wastewater during cleaning. A valve 17 is fixedly connected to the middle of the sand outlet pipe 16 to control the opening and closing of the sand outlet pipe 16.

The interior of the fixing block 11 is fixedly connected to the outer periphery of the motor 10 to support the motor 10, enabling the motor 10 to work better. The side of the support column 19 is fixedly connected to the sand receiving groove 18, and the top of the support frame 6 is fixedly connected to the handle 12, which facilitates the installation and removal of the bucket lid 2 by the workers.

[0035] Working principle: When cleaning the sand mixer, water and acetone solution for decomposing resin are first injected into the mixing drum 1 through the feed inlet 3 and liquid inlet pipe 4, respectively. Then, the drive motor 10 operates, which drives gear 2 9 and connecting rod 21 to rotate. When gear 2 9 rotates, it drives gear 1 7 and gear 3 14 to rotate simultaneously, thereby causing mixing roller 1 8 and mixing roller 2 13 to rotate. When connecting rod 21 rotates, it drives scraper 20 to scrape along the inner wall and bottom of the mixing drum 1. After cleaning, Open valve 17 to discharge water from sand outlet pipe 16, thereby cleaning the sand mixer and improving its service life. When maintenance of the mixing roller is required, pull the lever 5 outward to move the locking block 24 and squeeze the spring 23. When the spring 23 is compressed, the locking block 24 will disengage from the locking groove 25, thereby disassembling the bucket cover 2. Similarly, the bucket cover 2 can be installed, thus achieving convenient maintenance of the mixing roller, saving manpower and improving work efficiency.
