[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Referring to Figures 1-5, a novel energy-saving, safe, and efficient open mill includes a base 1. A mounting base 2 is fixedly connected to the bottom of the base 1. A collection box 3 is slidably connected inside the mounting base 2. A handle 11 is fixedly connected to the front end of the collection box 3. Mounting plates 4 are fixedly connected to both sides of the top of the base 1. A heating roller 5 is rotatably connected to the front inner side of the mounting plate 4. A servo motor 6 is fixedly connected to the right end of the heating roller 5. A gear 8 is fixedly connected to the left end of the heating roller 5. A heating roller 7 is rotatably connected to the rear inner side of the mounting plate 4. A gear 9 is fixedly connected to the left end of the heating roller 7. The positions of gear 8 and gear 9 correspond, and the gears 8 and 9 are located on opposite sides of each other. The mounting plate 4 has a sealing groove 10 on its top, and a sealing block 15 is slidably connected inside the sealing groove 10. The length and width of the sealing groove 10 are the same as the length and width of the sealing block 15, and the sealing block 15 is tightly fitted to the inner wall of the sealing groove 10. A heat insulation cover 13 is fixedly connected to the top of the sealing block 15. A second sealing block 16 is fixedly connected to the rear end of the inner side of the heat insulation cover 13. A second sealing groove 12 is opened at the rear end of the mounting plate 4. The position of the second sealing groove 12 corresponds to the position of the second sealing block 16, and the second sealing block 16 is tightly fitted to the inner wall of the second sealing groove 12. A handle 17 is fixedly connected to the rear end of the heat insulation cover 13, and a discharge port 14 is fixedly connected to the top of the heat insulation cover 13.
[0026] Working principle: In use, the operator first starts heating roller 5, heating roller 7, and servo motor 6. Servo motor 6 drives heating roller 5 to rotate, which in turn drives gear 9 to rotate via gear 8. Gear 9 then drives heating roller 7 to rotate in the opposite direction. At this time, the operator opens the feeding port 14 to feed in the raw material, and heating rollers 5 and 7 can then process the raw material. The operator can perform corresponding operations through the opening on the front. The heat generated by heating rollers 5 and 7 during operation is blocked and insulated by the mounting plate 4 and the heat insulation cover 13, preventing the operator from accidentally touching and getting burned. This also prevents the heat from dissipating rapidly into the air from these directions, reducing the rate of heat loss, improving heating efficiency, saving energy consumption, and facilitating safe use. The residual raw material generated during processing will fall into the collection box 3 for easy disposal by the operator.
[0027] Compared with related technologies, the new energy-saving, safe and efficient open mill provided by this utility model has the following beneficial effects: by setting a second sealing groove 12, a second sealing block 16 and so on, in conjunction with the heat insulation cover 13, the heat insulation cover 13 can be installed on the mounting plate 4 by sliding the first sealing block 15 and the second sealing block 16 into the first sealing groove 10 and the second sealing groove 12, thereby sealing and insulating the top and rear of the mounting plate 4, avoiding accidental burns to the workers, reducing the rate of heat loss, improving heating efficiency, saving energy consumption, and facilitating safe use.
[0028] Example 2:
[0029] Referring to Figures 1-6, the top of the mounting plate 4 has a sealing groove 10, and a sealing block 15 is slidably connected inside the sealing groove 10. The length and width of the sealing groove 10 are the same as the length and width of the sealing block 15, and the sealing block 15 is tightly fitted to the inner wall of the sealing groove 10. The top of the sealing block 15 is fixedly connected to a heat insulation cover 13, and the inner rear end of the heat insulation cover 13 is fixedly connected to a sealing block 16. The rear end of the mounting plate 4 has a sealing groove 12, and the position of the sealing groove 12 corresponds to the position of the sealing block 16. The sealing block 16 is tightly fitted to the inner wall of the sealing groove 12. The rear end of the heat insulation cover 13 is fixedly connected to a handle 17, and the top of the heat insulation cover 13 is fixedly connected to a discharge port 14.
[0030] Working principle: When the staff needs to clean and maintain heating roller 15 and heating roller 27, the staff only needs to hold the handle 17 on the back of the insulation cover 13 and pull it backward to pull the sealing block 15 and sealing block 26 out of the sealing groove 10 and sealing groove 22, thereby quickly separating the insulation cover 13 from the mounting plate 4. At this time, heating roller 15 and heating roller 27 will be exposed on the outside, which is convenient for the staff to clean and maintain and easy to use.
[0031] Compared with related technologies, the new energy-saving, safe and efficient open mill provided by this utility model has the following beneficial effects: by using the heat insulation cover 13 and the mounting plate 4 in conjunction, by holding the heat insulation cover 13 and pulling the handle 17 backward, the sealing block 15 and the sealing block 16 can be pulled out from the sealing groove 10 and the sealing groove 12, thereby quickly separating the heat insulation cover 13 from the mounting plate 4, which is convenient for workers to clean and maintain, and easy for workers to use.
