Description

Technical Field

[0001] The utility model relates to a novel plunger-type biomass forming machine, which is intended to meet the requirements for compact forming of biomass particles. Background Art

[0002] Currently, biomass forming machines on the market mostly use roller type, screw extrusion type and piston stamping type. Among them, most of the spiral forming machines have problems such as high product energy consumption and severe machine wear. The equipment cost of roller forming machines is relatively high. In comparison, the piston forming machine has more prominent advantages, but still needs further improvement.

[0003] The utility model patent with the authorization announcement number CN203792762U discloses a plunger-type biomass molding machine, including: a fixed main shaft; a swash plate driving large gear arranged on the main shaft, and a swash plate fixedly connected to the lower part of the swash plate driving large gear; a plunger sleeve arranged on the main shaft; when the swash plate rotates, the plunger is pressed, and the plunger squeezes the material into the compression hole, and the material is extruded from the mold. This utility model overcomes the wear problem between the molding mold and the pressure roller of the existing product, and can ensure high production efficiency, but this utility model patent does not solve the following problems.

[0004] Traditional mechanical plunger forming machines have the problems of large machine footprint, poor stability and high noise, and ordinary piston stamping forming machines do not use external heating forming methods, and the forming effect is looser than that of spiral extrusion machines. The utility model aims to study a more stable and sophisticated plunger biomass forming machine, which adopts extrusion plate extrusion forming and high-temperature carbonization to make the biomass particles more densely formed. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the utility model aims to design a new type of plunger biomass molding machine to solve the problems mentioned in the background technology. Specifically, the main structure of the device includes a heating coil, an outlet sleeve, a molding sleeve, a reciprocating mechanism housing, a speed reduction motor, a motor mounting frame, a box, an extrusion plate, a propulsion head, a nut, a reciprocating screw, a thrust bearing, a deep groove ball bearing, a lock nut, and a reciprocating mechanism end cover. The speed reduction motor is connected to the reciprocating screw, and the reciprocating screw is closely matched with the propulsion head through the nut. The function of the reciprocating screw is to enable the slider to realize reciprocating motion without changing the rotation direction of the main shaft. After the speed reduction motor is started, it drives the connected reciprocating screw to move, thereby driving the propulsion head connected to the reciprocating screw to perform reciprocating linear compression motion. In order to reduce the volume and space of the machine, increase the thrust, increase the stroke, enhance the stability of the machine and reduce vibration noise, the traditional mechanical piston biomass molding machine is innovatively optimized, and the reciprocating screw structure is used to replace the traditional crank connecting rod mechanism. Biomass raw materials are added to the molding sleeve, and the reciprocating screw drives the propulsion head to perform reciprocating linear motion to perform compression molding tests on the biomass raw materials.

[0006] When the biomass raw material is pushed by the reciprocating screw and gradually compressed to the outlet sleeve, the inverted cone structure of the outlet sleeve can better squeeze the raw material, making the biomass raw material more compact and compact.

[0007] In the utility model, the reciprocating screw uses two bearings, a thrust bearing and a deep groove ball bearing, wherein the deep groove ball bearing cooperates with the end cover of the reciprocating mechanism to bear the force of the reciprocating motion of the reciprocating screw to the greatest extent, increase the stability of the machine, and solve the problem of high noise. At the same time, the lock nut tightens the reciprocating screw to adjust the mechanism gap and manually adjust the stability of the machine.

[0008] The biomass raw materials are formed by the forming sleeve part and arrive at the heating coil part through the outlet sleeve for high-temperature carbonization, which improves the durability and resistance to breakage of the biomass particles and achieves a better forming effect.

[0009] When the biomass forming particles pass through the extrusion plate at the end of the sleeve forming part, secondary extrusion forming is performed to form several columnar biomass forming particles through the extrusion plate, which solves the problem that only one biomass forming particle can be compressed in a single reciprocating motion. The secondary extrusion makes the biomass dense forming effect better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] Reference Figure 1A new plunger-type biomass molding machine is mainly composed of a heating coil 1, an outlet sleeve 2, a molding sleeve 3, a reciprocating mechanism housing 4, a speed reduction motor 5, a motor mounting frame 6, a box body 7, an extrusion plate 8, a propulsion head 9, a nut 10, a reciprocating screw 11, a thrust bearing 12, a deep groove ball bearing 13, a lock nut 14, a reciprocating mechanism end cover 15, etc.

[0023] The box 7 is as follows Figure 2 As shown, the left hole 71 of the box body is connected to the outlet sleeve 2, and the right hole 72 of the box body is connected to the motor mounting frame 6, and the middle is responsible for connecting the forming sleeve 3 with the reciprocating mechanism housing 4.

[0024] The main mechanism connection of the novel plunger-type biomass molding machine is as follows: Figure 3 As shown, the speed reduction motor 5 is connected to the reciprocating screw 11 through the motor mounting bracket 6, and the reciprocating screw 11 and the propulsion head 9 are tightly matched through the threads on the nut 10.

[0025] In the device, reference Figure 4 , 5 The push head connecting key 91 cooperates with the keyway 41 of the reciprocating mechanism housing, so that the push head can slide freely in the reciprocating mechanism housing 4, and the reciprocating mechanism housing and the reciprocating mechanism end cover 15 have an interference fit, such as Figure 6 .

[0026] The internal structure of the reciprocating mechanism of the novel plunger-type biomass molding machine is as follows Figure 7 When the reciprocating screw 11 performs reciprocating linear motion, two bearings are used, a thrust bearing 12 and a deep groove ball bearing 13. The deep groove ball bearing 13 and the reciprocating mechanism end cover 15 are fixed on the reciprocating screw 11 with clearance fit. The reciprocating mechanism end cover 15 is tightly fitted on the outside of the reciprocating mechanism housing 4 to maximize the force of the movement of the screw 11. The mechanism clearance can be adjusted by tightening with a lock nut 14.

[0027] More specifically, when the biomass raw material is fed from the forming sleeve 3, the speed-regulating motor 5 drives the reciprocating screw 11 to move, and the propulsion head 9 connected to the reciprocating screw 11 through the nut 10 makes a reciprocating linear motion in the reciprocating mechanism housing 4, so that the biomass raw material passes through the forming sleeve 3 and is pushed toward the outlet sleeve 2. The specific process can be seen Figure 8 , 9 As shown. The raw material passes through the outlet sleeve 2 as Fig.10 As shown, Fig.11 It is a cross-sectional structure of the outlet sleeve 2 and the external heating coil 1, wherein the forming sleeve 3 is tightly connected to the sleeve bottom 23 by welding, so that the biomass raw material can pass smoothly. The raw material is squeezed by the inverted cone structure in the middle part 22 of the sleeve and then compressed and formed at the sleeve forming part 21.

[0028] The outlet sleeve 2 is as follows Fig.10 , 11 As shown, the extrusion plate 8 is installed at the connection between the sleeve forming part 21 and the sleeve middle part 22 in an interference fit manner, and is welded to make it more secure. The biomass raw material passes through the extrusion plate 8 and is extruded into several columnar biomass forming particles, which satisfies the secondary compression molding of multiple particles, making the formed particles more compact. The extrusion plate 8 is in the shape of a porous disc. Fig.12 The schematic diagram of the specific structure of the extrusion plate 8 is shown in FIG. The biomass particles after secondary compression molding pass through the heating coil 1 attached to the outlet sleeve 2, such as Fig.10 and Fig.11 As shown, the biomass particles are carbonized at high temperature to improve the durability and resistance to breakage of the biomass particles, making the molding effect better.
