Description

Technical Field

[0001] This utility model relates to the technical field of pellet extrusion molding, specifically to a biomass pellet extrusion molding device. Background Technology

[0002] Biomass pellets are made from agricultural and forestry waste such as straw, branches, peanut shells, rice husks, and forestry residues, with a density of approximately 1.1–1.3 t / m³ (compared to a raw material density of only 0.1–0.13 t / m³). They are cold-pressed through processes such as crushing, mixing, extrusion, and drying to achieve the solidification and utilization of biomass resources.

[0003] An existing biomass pellet mill forming and pressing structure, such as the one described in patent publication number CN222844854U, allows the pressing groove to rotate 180° after pressing. This innovative design allows the pressing groove to lock into the feeding hole, and the pellets will then automatically fall onto the conveyor belt, thus achieving convenient feeding. This utility model patent overcomes the problem of difficult pellet removal in traditional pressing devices, realizing automatic feeding. Operators only need to simply start the motor to automatically release the formed pellets onto the conveyor belt, eliminating the tedious manual removal steps, improving production efficiency, reducing the possibility of pellet damage or flaking, and thus improving the forming effect and product quality.

[0004] However, because the device relies on a motor to drive the side-connected pressure frame, the load is large when it is flipped, resulting in poor reliability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a biomass pellet extrusion molding device with a centrally connected flipping mechanism and a vibration mechanism for material discharge, thereby reducing operating load, improving discharge efficiency, and increasing reliability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass pellet extrusion molding device, comprising an outer frame, an extrusion cylinder, a telescopic rod, an extrusion die, a tilting drive motor, a reducer, a synchronous shaft, a rotation constraint sleeve, a second outer frame, connecting springs, a pressure groove frame, and a vibration source. The top center of the outer frame is connected to the bottom of the extrusion cylinder, the output end of the extrusion cylinder is vertically slidably connected to the outer side of the telescopic rod, the bottom of the telescopic rod is connected to the top center of the extrusion die, the left center of the outer frame is connected to the right side of the reducer, the input end of the reducer is connected to the output end of the tilting drive motor, and the output end of the reducer is connected to the outer end of the left synchronous shaft. Another set of synchronous shafts is rotatably connected to the right center of the inner right side of the outer frame via the rotation constraint sleeve. The two sets of synchronous shafts are coaxially connected to the middle of the left and right sides of the second outer frame. The inner side of the second outer frame is connected to the outer side of the pressure groove frame via multiple sets of connecting springs. A vibration source is provided at the center of the bottom side of the pressure groove frame, and an auxiliary fixing mechanism is also provided between the pressure groove frame and the outer frame.

[0007] Preferably, the auxiliary fixing mechanism includes an electric latch and a pin slot frame. A set of electric latches is respectively provided on the front and rear sides of the lower part of the outer frame, and a set of pin slot frames is respectively connected to the front and rear parts of the left and right sides of the pressing frame, with each set of electric latches corresponding to a set of pin slot frames.

[0008] Preferably, it also includes chamfered grooves, with a set of chamfered grooves provided on the outer side of the inner groove of each set of pin slots.

[0009] Preferably, it also includes a ventilated plate, and a set of ventilated plates are respectively provided on the lower inner side of the front and rear sides of the pressure groove frame.

[0010] Preferably, it also includes an oil injection nozzle, which is provided on the outer side of the rotation constraint sleeve, and the output side of the oil injection nozzle is connected to the inner wall of the rotation constraint sleeve.

[0011] Preferably, it also includes an oil filling cap, wherein the outer side of the oil filling nozzle and the inner side of the oil filling cap are detachably installed.

[0012] Compared with the prior art, the present invention provides a biomass pellet extrusion molding device, which has the following beneficial effects:

[0013] When the outer frame 2 and the pressing frame are in the forward orientation and fixed by the auxiliary fixing mechanism, the extrusion cylinder can run inside the outer frame, acting on the telescopic rod to slide down, causing the extrusion die to act inward on the inside of the pressing frame to press the biomass raw material into blocks. After completion, the extrusion cylinder acts on the telescopic rod to lift, causing the extrusion die to return to its original position. Then, the fixing mechanism is released, and the tilting drive motor runs, which is decelerated by the reducer, causing the left synchronous shaft to drive the outer frame 2. Another set of synchronous shafts rotates under the constraint of the rotation constraint sleeve, thereby causing the pressing frame connected to the outer frame 2 to tilt, so that the top of the pressing frame tilts downward. The vibration source runs, causing the pressing frame to vibrate at high frequency under the connection of multiple sets of connecting springs, thereby accelerating the unloading. A tilting mechanism connected in the middle is set up, which works in conjunction with the vibration mechanism for material discharge, reducing the operating load, improving the discharge efficiency, and increasing reliability.

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.

[0020] Example 1

[0021] Please see Figure 1-4 A biomass pellet extrusion molding device includes an outer frame 1, an extrusion cylinder 2, a telescopic rod 3, an extrusion die 4, a tilting drive motor 5, a reducer 6, a synchronous shaft 7, a rotation constraint sleeve 8, a second outer frame 9, connecting springs 10, a pressing frame 11, and a vibration source 12. The top middle of the outer frame 1 is connected to the bottom of the extrusion cylinder 2. The output end of the extrusion cylinder 2 is vertically slidably connected to the outer side of the telescopic rod 3. The bottom of the telescopic rod 3 is connected to the top middle of the extrusion die 4. The left middle of the outer frame 1 is connected to the right side of the reducer 6. The input end of the reducer 6 is connected to the output end of the tilting drive motor 5. The output end of the reducer 6 is connected to the outer end of the left synchronous shaft 7. Another set of synchronous shafts 7 is rotatably connected to the right middle of the inner side of the outer frame 1 via the rotation constraint sleeve 8. The two sets of synchronous shafts 7 are coaxially connected to the middle of the left and right sides of the second outer frame 9. The inner side of the second outer frame 9 is connected to the outer side of the pressing frame 11 via multiple sets of connecting springs 10. A vibration source 12 is provided at the bottom center of frame 11, and an auxiliary fixing mechanism is also provided between the pressing frame 11 and the outer frame 1. When the outer frame 9 and the pressing frame 11 are in the positive position and are fixed by the auxiliary fixing mechanism, they can run inside the outer frame 1 through the extrusion cylinder 2, which acts on the telescopic rod 3 to slide down, so that the extrusion die 4 acts inward on the inside of the pressing frame 11 to press the biomass raw material into blocks. After completion, the extrusion cylinder 2 acts on the telescopic rod 3 to lift, so that the extrusion die 4 returns to its original position. Then the fixing of the auxiliary fixing mechanism is released, and the flipping drive motor 5 runs. After the speed reduction by the reducer 6, the left synchronous shaft 7 drives the outer frame 9, and another set of synchronous shafts 7 rotates under the constraint of the rotation constraint sleeve 8. Thus, the pressing frame 11 connected to the outer frame 9 flips, so that the upper opening of the pressing frame 11 tilts downward. The vibration source 12 runs, so that the pressing frame 11 vibrates at high frequency under the connection of multiple sets of connecting springs 10, thereby accelerating the pouring out.

A set of electric pins 13 is respectively installed on the front and rear sides of the lower inner part of the outer frame 1, and a set of pin slot frames 14 is respectively connected to the front and rear parts of the left and right sides of the pressing frame 11. Each set of electric pins 13 corresponds to a set of pin slot frames 14. When the pressing frame 11 is in a flat position, the electric pins 13 can be inserted into the pin slot frames 14, thereby reinforcing the pressing frame 11 and improving its stability through the connection between the electric pins 13 and the pin slot frames 14.

[0023] It also includes a chamfered groove 15. Each set of pin slot brackets 14 has a set of chamfered grooves 15 on the outer side of the inner groove. The chamfered grooves 15 can widen the inner groove of the pin slot brackets 14, making it easier for the electric pin 13 to be inserted into the pin slot brackets 14 and improving convenience.

The two sets of synchronous shafts 7 are coaxially connected to the middle of the left and right sides of the second outer frame 9.
