Description

Technical Field

[0001] This utility model relates to the field of pressure roller shell technology, specifically a pressure roller shell accessory for a feed machine. Background Technology

[0002] When the feed machine is working, as the pressure roller shell rotates, the material is subjected to compression force and gradually forms granules. In this process, the pressure roller shell plays a crucial role. It not only has to withstand the huge pressure from the material, but also has to ensure the smooth progress of the compression process. At the same time, the surface quality and shape of the pressure roller shell directly affect the quality and appearance of the produced granules.

[0003] The prior art discloses patent application number "CN201821259487.5", which discloses a pressure roller shell for a briquetting machine, including a sealing groove, an inner shell of the pressure roller, and positioning holes. Two sealing grooves are provided in the middle of the inner circumferential surface of the inner shell of the pressure roller, and positioning holes are provided on both sides of the inner shell of the pressure roller. An outer ring of the pressure roller shell is provided in the middle of the circumferential surface of the inner shell of the pressure roller, and a tungsten steel plating is provided on the circumferential surface of the outer ring of the pressure roller shell.

[0004] The pressure roller shell can only increase the wear resistance of the outer ring of the pressure roller shell by using tungsten steel coating. However, in actual use, the pressure roller shell parts of the feed machine are used to process materials for a long time. The materials will rub against the pressure roller shell parts, causing wear and tear, which will affect the processing performance of the pressure roller shell parts and make them inconvenient to use.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, a feed mill pressure roller shell accessory includes a pressure roller shell accessory 1 and a pressure roller shell accessory 2. Two symmetrically arranged circular baffles 4 are snapped between the pressure roller shell accessory 1 and the pressure roller shell accessory 2. Each of the two circular baffles 4 has an array of guide posts 5 fixedly connected to one side. The outer surface of the pressure roller shell accessory 1 is provided with an array of grooves 10. The grooves 10 can increase the friction between the pressure roller shell accessory and the material, so as to reduce the movement of the feed mill pressure roller shell accessory and reduce wear, thereby improving the service life of the feed mill pressure roller shell accessory.

[0027] Two circular baffles 4 are each connected to a fixed rod 6 in an array on one side. The inside of the pressure roller shell accessory 1 is slidably engaged with an array of first movable clamping plates 7. The outer surface of the pressure roller shell accessory 2 is slidably engaged with an array of second movable clamping plates 8. By setting the fixed rod 6, the first movable clamping plates 7 and the second movable clamping plates 8 can be used to engage the fixed rod 6 to position the circular baffle 4. The first movable clamping plates 7 and the second movable clamping plates 8 are used to position the fixed rod 6. Both ends of the pressure roller shell accessory 1 and the pressure roller shell accessory 2 are engaged with sealing seats 12. The outer surfaces of the two sealing seats 12 are fixedly installed with retaining rings 13. The outer surfaces of the two sealing seats 12 are slidably installed with an array of positioning rods 14.

[0028] Both ends of the pressure roller shell accessory 1 are fixedly installed with limit rings 11. A connecting spring 15 is fixedly connected between the positioning rod 14 and the sealing seat 12. One side of the positioning rod 14 passes through the sealing seat 12 and extends into the interior of the sealing seat 12. A fixed side plate 17 is fixedly connected to one side of the positioning rod 14. A limit bolt 18 is threadedly connected to the inner side of the sealing seat 12. By setting the limit bolt 18, rotating the limit bolt 18 can squeeze the fixed side plate 17 to retract the elastic positioning rod 14, thereby releasing the limit on the sealing seat 12 and removing the sealing seat 12, which is convenient to use.

[0029] Both ends of the pressure roller shell accessory 1 are fixedly connected with arrayed baffles 19. Inside the baffles 19, a movable rotating plate 20 for fixing the retaining ring 13 is rotatably installed. One side of each of the two sealing seats 12 is provided with an arrayed first square groove 3 and a second square groove 16.

[0030] The inside of the pressure roller shell accessory 1 has an array of circular holes 21. The circular holes 21 are adapted to the positioning rod 14. One side of the positioning rod 14 is engaged with the inside of the pressure roller shell accessory 1 through the circular holes 21.

[0031] The second pressure roller housing accessory 2 is located inside the first pressure roller housing accessory 1. The first movable clamping plate 7 and the second movable clamping plate 8 both pass through the fixing rod 6 and extend to one side of the fixing rod 6. The fixing rod 6 is threaded with fastening bolts 9 for fixing the first movable clamping plate 7 and the second movable clamping plate 8.

[0032] The sealing seat 12 has an array of mounting grooves 22 on one side. The mounting grooves 22 are adapted to the guide post 5. One side of the guide post 5 is engaged with one side of the sealing seat 12 through the mounting grooves 22.

[0033] The working principle of the feed mill pressure roller shell accessory provided by this utility model is as follows:

[0034] By sequentially attaching two circular baffles 4 between roller shell accessory 1 and roller shell accessory 2, and then moving the first movable plate 7 and the second movable plate 8 respectively, the two sets of movable plates can be attached to the inside of the fixed rod 6. Then, the fastening bolt 9 is tightened to press and fix the two sets of movable plates, so as to initially position the two circular baffles 4. Next, the two sealing seats 12 are attached to the two ends of roller shell accessory 1 and roller shell accessory 2. Then, the limiting bolt 18 is tightened to release the limitation on the fixed side plate 17, so that the positioning rod 14 with the connecting spring 15 can be extended and attached to the circular hole 21 of roller shell accessory 1, which is used to assemble and fix the sealing seat 12 to form the feed machine roller shell accessory. At the same time, it is also convenient to remove the circular baffles 4 and the sealing seats 12, so that the feed machine roller shell accessory can be quickly replaced without replacing all of them, which is beneficial to improving the processing performance of the feed machine roller shell accessory.

[0035] As the sealing seat 12 engages, the retaining ring 13 at the sealing seat 12 will also engage with the inside of the limiting ring 11. Then, the mounting groove 22 at the sealing seat 12 can engage with the guide post 5 at the annular baffle 4 to connect the annular baffle 4 and the sealing seat 12, ensuring the stability of both. Next, the movable rotating plate 20 at the baffle 19 is rotated so that the movable rotating plate 20 can be pressed against the retaining ring 13 to further stabilize the positioning retaining ring 13 and strengthen the overall robustness of the feed mill pressure roller shell accessories.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
