[0016] 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.

[0017] Please see Figure 1-4An adjustable tilt roller assembly includes a base 1, a first fixing frame 6 fixedly connected to both sides of the top of the base 1, a telescopic cylinder 19 fixedly connected to the four corners of the top of the base 1, auxiliary rollers 11 inclined outward on both sides of the top of the base 1, and a flexible component with adjustable angle provided on the side wall of the first fixing frame 6. The flexible component includes a movable base 9, which is provided in two sets, with the outer side of each set of first fixed frames 6 passing through the sidewalls of the two sets of first fixed frames 6 laterally. The front and rear ends of the movable base 9 are fixedly connected to external rods 24. The front and rear ends of the first fixed frames 6 are vertically provided with through slots 7. The external rods 24 pass through the interior of the through slots 7, and their outer ends are fixedly connected to a limiting outer plate 8. Fastening bolts 22 are provided through both sides of the limiting outer plate 8. The outer ends of the fastening bolts 22 are fixedly connected to a second knob 23, and the other end of the fastening bolts 22 passes through the interior of the first fixed frame 6. The front and rear ends of the other side of the movable seat 9 are fixedly connected to the first movable frame 10. The top and bottom ends of the auxiliary roller 11 are fixedly connected to the fixed seats. The front and rear ends of the top fixed seats of the auxiliary roller 11 are fixedly connected to the second movable block 15. The outer end of the second movable block 15 is movably connected to the inside of the first movable frame 10. Furthermore, when the movable seat 9 moves up and down along the through groove 7, the top of the auxiliary roller 11 will rotate around the first movable block 14 at the bottom as the height of the movable seat 9 changes, thereby realizing the tilt angle adjustment. During this process, the auxiliary roller 11 adjusts the horizontal displacement generated by the tilt angle. The first movable frame 10 has a groove-shaped structure, and the second movable block 15 can slide slightly in the horizontal direction in the groove to adapt to the horizontal displacement caused by the change in the top height. Specifically, such as Figure 1 and Figure 2 As shown, when in use, the movable seat 9 passes horizontally through the side wall of the first fixed frame 6. The movable seat 9 is pushed to a suitable height according to the actual situation. The external rod 24 passes through the inside of the through groove 7, causing the limiting outer plate 8 to move accordingly. The second knob 23 is rotated in sequence, causing the fastening bolt 22 to pass through the inside of the limiting outer plate 8 and fix the movable seat 9 in the current position.

[0018] The base 1 is fixedly connected to the two sides of the external mounting bracket 2. The top of the external mounting bracket 2 extends outward and bends, and the bottom of the external mounting bracket 2 has an inward groove that is hollow. The top of the external mounting bracket 2 has a through-hole positioning groove 4, and the inside of the positioning groove 4 is vertically threaded with a mounting bolt 3. The top of the mounting bolt 3 is fixedly connected with a first knob 5, and the bottom of the mounting bolt 3 is pointed. Specifically, such as Figure 1 and Figure 3As shown, when in use, the external mounting bracket 2 is placed in the equipment, and the mounting bolt 3 is aligned with the corresponding positioning groove 4. Then, the first knob 5 is turned in sequence to move the mounting bolt 3 through the interior of the positioning groove 4 and downward, so as to quickly move the base 1 in all directions.

[0019] The top of the telescopic cylinder 19 is fixedly connected to a support base plate 18. The top two sides of the support base plate 18 are fixedly connected to a second fixed frame 16. The height of the second fixed frame 16 is lower than that of the first fixed frame 6. The top of the second fixed frame 16 is movably inserted with a second movable frame 12. The front and rear ends of the bottom fixed seat of the auxiliary roller 11 are fixedly connected to a first movable block 14. The first movable block 14 is movably connected to the second movable frame 12. The telescopic cylinder 19 is spirally provided with a buffer spring 20. The top two sides of the base 1 are fixedly connected to a vertical frame 21. Furthermore, the telescopic cylinder 19 has a two-section structure, with the upper part fixed to the supporting base plate 18 and the lower part fixed to the base 1; Furthermore, when the main idler roller 13 is subjected to material pressure or vibration transmitted by the conveyor belt, the support base plate 18 will generate a slight vertical pressure fluctuation. At this time, the buffer spring 20 can absorb the pressure fluctuation through its own compression and rebound. When the pressure increases, the spring is compressed, and when the pressure decreases, the spring rebounds, thereby achieving the function of reducing the vibration force of the support base plate 18. A limit socket 25 is fixedly connected to the top of the side wall of the upright 21, and a connecting plate 26 is fixedly connected to the outer end of the bottom of the second fixed frame 16; The inner wall of the limit socket 25 is provided with a mounting groove 27. The limit socket 25 is sleeved on the outside of the connecting plate 26, and the outer end of the connecting plate 26 is inserted into the inside of the mounting groove 27. A main support roller 13 is arranged parallel above the support base plate 18. A bearing 17 is arranged transversely inside the main support roller 13. The two sides of the bearing 17 are movably connected to the side walls of two sets of second fixed frames 16 respectively. Specifically, such as Figure 1 and Figure 4 As shown, during use, the support base plate 18 and the telescopic cylinder 19 cooperate with each other to provide strong support for the bottom of the two sets of second fixed frames 16, enhance the stability of the main roller 13 operation, reduce the vibration force of the support base plate 18 by using the buffer spring 20, and fit the limit socket 25 on the outside of the second fixed frame 16. The connecting plate 26 is fixed inside the mounting groove 27 by using the plug-in connection method, which improves the stability of the second fixed frame 16 itself.

[0020] Working principle: When in use, the movable seat 9 passes horizontally through the side wall of the first fixed frame 6. The movable seat 9 is pushed to a suitable height according to the actual situation. The external rod 24 passes through the inside of the through groove 7, causing the limiting outer plate 8 to move accordingly. The second knob 23 is rotated in sequence, causing the fastening bolt 22 to pass through the inside of the limiting outer plate 8 and fix the movable seat 9 in the current position. The external mounting frame 2 is placed in the equipment. After the mounting bolt 3 is aligned with the corresponding positioning groove 4, the first knob 5 is rotated in sequence to move the mounting bolt 3 through the inside of the positioning groove 4 and downward, so as to quickly move the base 1 in all directions.
