AI Technical Summary
In existing environmentally friendly fuel production equipment, the crushed raw materials fall directly onto the auger rod, causing the raw materials of different particle sizes to mix, which may lead to the problem of loose pores in the formed particles.
A vibrating motor drives a cam to vibrate the screening plate, which screens out raw materials with suitable particle size. Raw materials with unsuitable particle size pass through the vibration of the screening plate to the collection box, where workers further crush them to avoid loose pores caused by larger particle size.
This technology enables particle size screening of raw materials, ensuring dense particles during subsequent extrusion molding and preventing loosening, thereby improving molding quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmentally friendly fuel production technology, and in particular to an extrusion molding device for environmentally friendly fuel production. Background Technology
[0002] Extrusion molding technology for producing environmentally friendly fuels is a core link in achieving efficient utilization of biomass resources. It compresses agricultural and forestry waste such as straw, sawdust, and rice husks into high-density pellet fuel through mechanical pressure, thereby realizing resource utilization.
[0003] A search revealed Chinese patent publication number CN222586479U, which discloses a biomass fuel pellet forming machine. This patent uses a motor-driven crushing roller to crush the raw material. The crushed material falls onto an auger rod and is pushed to a shaping disc, where it is extruded into a long strip through through holes. The auger rod drives a cutter to cut the long strip into pellet fuel. This device has certain problems: the crushed material falls directly onto the auger rod, causing materials of different particle sizes to mix before extrusion molding. This may result in larger particle sizes, causing pores in the formed pellets and making them loose inside. Utility Model Content
[0004] The purpose of this invention is to provide an extrusion molding device for the production of environmentally friendly fuels in order to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] An extrusion molding apparatus for producing environmentally friendly fuels includes a housing, a feed hopper fixedly connected to the upper end of the housing, a crushing mechanism located at the upper end of the housing, and a screening mechanism located inside the housing. The screening mechanism includes a vibrating motor, which is fixedly installed on one side of the housing, and a cam is fixedly connected to the output shaft of the vibrating motor.
[0007] A screening plate is hinged to the side of the box away from the cam. The screening plate is tilted upward on the side away from its own hinge axis. The cam is located below the screening plate. A guide plate parallel to the screening plate is provided below the cam. The guide plate is fixedly connected to the side wall of the box. A fixing block is fixedly connected to the side of the box near the cam. A spring is fixedly connected between the fixing block and the screening plate.

[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] like Figures 1-5 As shown, an extrusion molding device for producing environmentally friendly fuel includes a housing 101, a feed hopper 102 fixedly connected to the upper end of the housing 101, a crushing mechanism provided at the upper end of the housing 101, and a screening mechanism provided inside the housing 101. The screening mechanism includes a vibrating motor 404, which is fixedly installed on one side of the housing 101, and a cam 405 is fixedly connected to the output shaft of the vibrating motor 404.
[0027] A screening plate 401 is hinged to the side of the housing 101 away from the cam 405. The screening plate 401 is inclined upward on the side away from its own hinge axis. The cam 405 is located below the screening plate 401. A guide plate 7 parallel to the screening plate 401 is provided below the cam 405. The guide plate 7 is fixedly connected to the side wall of the housing 101. A fixing block 402 is fixedly connected to the side of the housing 101 near the cam 405. A spring 403 is fixedly connected between the fixing block 402 and the screening plate 401. The raw material is poured into the housing 101 through the feed hopper 102. After being crushed by the crushing mechanism, the raw material falls onto the screening plate 401. On step 01, the vibration motor 404 is started, which drives the cam 405 to rotate and squeeze one end of the screening plate 401. The cam 405 continues to rotate, causing the spring 403 to deform and then recover its deformation, which drives the screening plate 401 to vibrate. The raw materials with suitable particle size are screened out and fall onto the guide plate 7. When the cam 405 rotates, it squeezes the guide plate 7 and vibrates, which guides the raw materials. The raw materials with unsuitable particles move away from the cam 405 as the screening plate 401 vibrates. Then, the workers crush the unqualified raw materials again to avoid the formation of local pores during subsequent extrusion due to the large particle size, which would cause the internal material to become loose.
[0028] A collection box 301 is fixedly connected to the side of the housing 101 away from the vibrating motor 404. The hinge shaft of the screening plate 401 is located at the lower end of the collection box 301. The collection box 301 is connected to the inside of the housing 101. An upward-opening door 302 is hinged to the side of the collection box 301 away from the housing 101. Raw material particles that are not up to standard move into the collection box 301 as the screening plate 401 vibrates. Then, the worker flips the upward-opening door 302 to clean out the raw material in the collection box 301 and pours it back into the housing 101 through the feed hopper 102.
[0029] The crushing mechanism includes two crushing rollers 201, which are symmetrically connected to the housing 101 and rotated in front and behind. The crushing rollers 201 are located above the screening plate 401.
[0030] A gear 202 is fixedly connected to one end of the crushing roller 201. The two symmetrical gears 202 mesh together. A drive motor 203 is fixedly installed on one side of the housing 101. The drive motor 203 is fixedly connected to the front crushing roller 201. When the drive motor 203 is started, the two crushing rollers 201 rotate in opposite directions through the meshing of the two gears 202, thereby crushing the raw material located between the two crushing rollers 201.
[0031] A material extrusion pipe 103 is fixedly connected to the side of the box 101 away from the collection box 301. The material extrusion pipe 103 is located at the lower end of the box 101, and a conveying trough is fixedly connected to the bottom wall of the box 101.
[0032] An auger 502 is rotatably connected inside the conveying trough. A power motor 501 is fixedly installed on one side of the housing 101. The output shaft of the power motor 501 is fixedly connected to the auger 502. The power motor 501 drives the auger 502 to rotate and convey the raw material particles into the extrusion pipe 103.
[0033] An extrusion plate 601 is fixedly installed on the side of the extrusion tube 103 away from the housing 101. A scraper 602 is fixedly connected to the rotating shaft of the auger 502. The scraper 602 abuts against the side of the extrusion plate 601 away from the housing 101. Raw material particles move into the extrusion tube 103 and are extruded through the extrusion plate 601. The scraper 602 scrapes the extrusion plate 601 to divide the material as the auger 502 rotates.
[0034] Working principle: During use, raw materials are poured into the housing 101 through the feed hopper 102. The drive motor 203 is started, and the two gears 202 mesh to cause the two crushing rollers 201 to rotate in opposite directions, thus crushing the raw materials located between the two crushing rollers 201. The crushed raw materials fall onto the screening plate 401. The vibration motor 404 is started, driving the cam 405 to rotate and squeeze one end of the screening plate 401. The continuous rotation of the cam 405 causes the spring 403 to deform and then recover its deformation, driving the screening plate 401 to vibrate. Raw materials of suitable particle size are screened out and fall onto the guide plate 7. The rotation of the cam 405 squeezes the guide plate... Vibration is generated on plate 7 to guide the raw material into the conveying trough. The power motor 501 drives the auger 502 to rotate, causing the raw material particles to move into the extrusion pipe 103 and be extruded through the extrusion plate 601. The scraper 602 scrapes the extrusion plate 601 to separate the particles as the auger 502 rotates. At the same time, raw material particles with unqualified particle size move into the collection box 301 as the screening plate 401 vibrates. Then, the worker flips the upper door 302 to clean the raw material in the collection box 301 and pours it back into the box 101 through the feed hopper 102 for crushing, so as to avoid the formation of local pores and internal loosening due to the large particle size during subsequent extrusion.

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.
