Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to an automatically regulating extrusion pressure type sealed feeding mechanism. Background Art

[0002] Compressible materials refer to materials whose volume is significantly reduced and density is increased under the action of external forces. They are suitable for many fields such as straw compression in industrial compression, and have the advantages of reducing the frequency of transportation. When compressing compressible materials, it is necessary to drive the compressible materials to be transported and moved to the inside of the compression structure to realize the compression operation.

[0003] However, the feeding device has the following defects when used specifically: 1. When existing compressible materials are conveyed through a sealed feeding mechanism, a sealed feeding and conveying system is required to prevent external gas from entering the interior of the compressible material and affecting its storage time. However, conventional feeding devices are generally arranged in a multi-stage plug-in seal and intermittent feeding manner, which easily leads to a complex feeding device (system) and a high failure rate. In particular, the connection between the two device tanks is prone to bridging, which hinders the normal flow and conveying of materials. At the same time, when the conveyed material is compressed, the compressed material is difficult to cooperate and conflict with the structure of the compressed material, and it is difficult to compress compressible materials of different densities, and the compression effect of the material is poor; 2. When the existing compressible materials are compressed by the compression structure inside the feeding device, due to the different gaps and densities between the compressible materials transported to the feeding device, the structure of the compressed materials is difficult to tightly contact with the compressible materials to achieve the compression operation of the compressible materials. At the same time, for compressible materials with higher humidity, it will hinder the close combination of the materials, resulting in a decrease in the compression density, affecting the compactness and quality of the product. And after the compression is completed, the material with higher humidity is more likely to expand and contract, resulting in unstable compression size. Summary of the invention

In the automatic adjustment extrusion pressure sealed feeding mechanism, when the spiral screw is driven to rotate to move and convey the compressible material, the force driving the spiral screw to rotate can synchronously drive the oblique oscillation rod and the material oscillation blade to reciprocate and rotate obliquely, breaking up and oscillating the compressible material entering the spiral outer shell for conveying and compression, reducing the probability of the compressible material sticking together, and improving the effect of subsequent heating and dehumidification of the compressible material. At the same time, the breaking up of the compressible material makes it more convenient and uniform when conveying the compressible material through the spiral screw, so that the compressible material conveyed to the inner side of the fan-shaped pressure regulating plate each time is relatively consistent, and the material after each compression is also relatively consistent, which is easier for subsequent packaging; 3. In the automatic adjustment extrusion pressure sealed feeding mechanism, when the compressible material moved to the inner part of the spiral outer shell is broken up, the force generated by the operation of the oblique oscillating rod will also drive the feeding bracket to rotate (continuously reverse), clearing the compressible material that has fallen and blocked the feeding bracket, reducing the probability of blockage and accumulation of compressible materials. At the same time, the design of the arc structure at the top of the guide bracket can reduce the probability of compressible materials sticking to the guide bracket when the compressible materials are unloaded and conveyed, and the compressible raw materials can more easily enter the inner part of the spiral outer shell through the through hole; 4. In the automatically adjustable extrusion pressure type sealed feeding mechanism, the feed sealing ring and the discharge sealing ring are installed on the front and rear sides of the fan-shaped pressure regulating plate by means of air bags, and the feed sealing ring and the discharge sealing ring are matched with the sealed tank structure connected on the left and right sides thereof.

Detailed implementation mode

[0018] In order to enable the personnel in the technical field to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application. Embodiment 1

[0019] Please refer to Figure 1 and Figure 10 , an automatic pressure-adjusting extrusion sealing feeding mechanism includes a spiral housing 10; a servo drive source 20 installed on one side of the spiral housing 10; a spiral feeding and extrusion mechanism 30 connected to the output end of the servo drive source 20 and extending into the spiral housing 10; an assembled heating component 40 installed inside the spiral feeding and extrusion mechanism 30 and extending outside the spiral housing 10. The spiral feeding and extrusion mechanism 30 includes: a main shaft 301 connected to the output end of the servo drive source 20 through a synchronous pulley and rotatably connected inside the spiral housing 10; a spiral screw 302 connected to the main shaft 301 and movably arranged inside the spiral housing 10; an oscillation and dispersion component 303 connected to the main shaft 301 through a synchronous pulley and extending above the spiral screw 302; an extrusion pressure-regulating structure 304 arranged outside the spiral screw 302 and at the inner wall of the spiral housing 10. A conical channel 3040 is arranged inside the extrusion pressure-regulating structure 304, and the spiral screw 302 is movably arranged inside the conical channel 3040. Among them, the inside of the spiral screw 302 is hollow, and the assembled heating component 40 is movably arranged inside the hollow part of the spiral screw 302.

[0020] In the present invention, the spiral housing 10 is composed of a plurality of sealed tank bodies 101 connected by screws. An extrusion pressure regulating structure 304 is installed on the inner wall of the sealed tank body 101. Among them, an inlet channel 102 communicates with the top of one spiral housing 10 close to the servo drive source 20. An oscillation and dispersion assembly 303 is installed inside the inlet channel 102. A discharge channel 103 communicates with the bottom of one spiral housing 10 close to the assembled heating assembly 40.

[0021] The above working principle: Through the spiral feeding and extrusion mechanism 30 composed of a plurality of sealed tank bodies 101, when compressing compressible materials, the materials can pass through the conveying force generated by the rotation of the main shaft 301 and the spiral screw 302 driven by the operation of the servo drive source 20 normally and smoothly, and move the materials normally and smoothly into the conical channel 3040 inside the extrusion pressure regulating structure 304. And through the structure of the conical channel 3040, the compressible materials are automatically compressed and moved to one side of the discharge channel 103 to automatically discharge the compressed materials. Among them, when the main shaft 301 operates, it can also drive the oscillation and dispersion assembly 303 to operate, and disperse the compressible materials that move and are conveyed into the inlet channel 102, reducing the probability of the compressible materials sticking together, ensuring that after the compressible materials enter the inside of the spiral housing 10, they are more easily heated and dehumidified by the assembled heating assembly 40, improving the effect of the compressed materials. And the dispersed compressible materials have a better compression effect during subsequent compression, ensuring the quality of the compressed materials.

[0022] In the present invention, the servo drive source 20 is preferably a servo motor.

[0023] An assembly bracket 1021 is installed inside the inlet channel 102. A through hole is provided eccentrically inside the assembly bracket 1021. Among them, a guide material bracket 1022 is installed on the top of the assembly bracket 1021 at the top. An oscillation and dispersion assembly 303 is rotatably connected between the two assembly brackets 1021.

[0024] Specific reference Figure 5 and Figure 7, the oscillation and dispersion assembly 303 includes: a transmission belt 3031 connected to the outside of the main shaft 301 through a synchronous pulley; a drive rod 3032 connected to the inside of the transmission belt 3031 through a synchronous pulley and extending into the inside of the inlet passage 102; a skew connecting block 3033 connected to the drive rod 3032 and movably arranged inside the inlet passage 102; an inclined oscillation rod 3034 rotatably connected to the skew connecting block 3033; a lifting movable block 3035 movably arranged outside the inclined oscillation rod 3034; lifting sliders 3036 rotatably connected to the left and right sides of the lifting movable block 3035; a vertical guide rod 3037 slidably connected to the lifting sliders 3036; and a feed support 3038 installed on the upper and lower sides of the vertical guide rod 3037.

[0025] In the present invention, there are two skew connecting blocks 3033, and an inclined oscillation rod 3034 is movably connected between the two skew connecting blocks 3033. Among them, a material oscillation blade 30341 is installed on the outside of the inclined oscillation rod 3034, and the material oscillation blade 30341 is movably arranged between the two feed supports 3038; a discharge through hole 30381 for the material to move and discharge is provided inside the feed support 3038, and the feed support 3038 is rotatably connected to the side of the assembly support 1021. Among them, the discharge through hole 30381 is consistent with the through hole provided inside the assembly support 1021, and the discharge through hole 30381 is arranged on the side of the vertical guide rod 3037.

[0026] In the automatic adjustment extrusion pressure type sealing feed mechanism of the present invention, when the main shaft 301 rotates, it will drive the transmission belt 3031 connected to its outside through a synchronous pulley to operate, and cause the drive rod 3032 connected to the inside of the transmission belt 3031 through a synchronous pulley to rotate. At this time, when the drive rod 3032 rotates, it will drive the skew connecting block 3033 installed at its bottom to rotate and operate, so that the inclined oscillation rod 3034 and the lifting movable block 3035 connected to the side of the skew connecting block 3033 move on the side of the lifting slider 3036 and rotate in the skew direction. At the same time, the lifting slider 3036 can move up and down a certain distance outside the vertical guide rod 3037, that is: the inclined oscillation rod 3034 moves up and down while performing skew rotation, improving the effect of the inclined oscillation rod 3034 and the material oscillation blade 30341 on oscillating and dispersing the material. Among them, the feed support 3038 will perform positive and negative rotations at a certain angle due to the operation of the inclined oscillation rod 3034, which can reduce the probability of the material accumulating and sticking to the feed support 3038.

[0027] Specific reference Figure 5 、 Figure 8 and Figure 9, the extrusion pressure regulating structure 304 includes: a spring mounting pin 3041 installed on the inner wall of the sealed tank body 101; a pressure regulating spring 3042 connected to the spring mounting pin 3041; a sector-shaped pressure regulating plate 3043 installed at the bottom of the pressure regulating spring 3042; a feed sealing ring 3044 installed on the feed port side of the sector-shaped pressure regulating plate 3043 and located inside the sealed tank body 101; a discharge sealing ring 3045 installed on the discharge port side of the sector-shaped pressure regulating plate 3043 and located inside the sealed tank body 101; an airbag 3046 installed on the sides of the feed sealing ring 3044 and the discharge sealing ring 3045 and abutting against the outer side of the sector-shaped pressure regulating plate 3043. Among them, the side of the airbag 3046 in contact with the sector-shaped pressure regulating plate 3043 is connected by an elastic adhesive material to remove the gap at the connection between the airbag 3046 and the sector-shaped pressure regulating plate 3043.

[0028] In the present invention, a plurality of spring mounting pins 3041, pressure regulating springs 3042 and sector-shaped pressure regulating plates 3043 are provided. A conical channel 3040 is formed between the plurality of sector-shaped pressure regulating plates 3043. Among them, the plurality of sector-shaped pressure regulating plates 3043 abut against each other in a scale-like manner, and there is no gap at the connection part between two adjacent sector-shaped pressure regulating plates 3043, and the pressure regulating springs 3042 are arranged obliquely.

[0029] In the automatic adjustment extrusion pressure type sealed feeding mechanism of the present invention, when the compressible material enters the inside of the conical channel 3040 formed by the plurality of sector-shaped pressure regulating plates 3043, it will squeeze the sector-shaped pressure regulating plate 3043 and the pressure regulating spring 3042 against which it abuts, and drive the sector-shaped pressure regulating plate 3043 to move. At this time, through the elastic force and elastic coefficient of the pressure regulating spring 3042, an extrusion force will be generated on the compressible material inside the sector-shaped pressure regulating plate 3043. With the structure of the conical channel 3040, the automatic extrusion operation of the compressible material is completed. Among them, the design of the feed sealing ring 3044 and the discharge sealing ring 3045 matches the structure of the sealed tank body 101 arranged on their left and right sides, and the conveying of the compressible material will not be hindered; the design of the airbag 3046, in cooperation with the pressure regulating spring 3042, ensures that the plurality of sector-shaped pressure regulating plates 3043 can abut tightly against each other, while avoiding the generation of gaps between the plurality of sector-shaped pressure regulating plates 3043 and improving the compression performance.

[0030] For specific reference Figure 10 , the assembled heating component 40 includes: a heating module 401 movably arranged at the inner bottom of the spiral screw 302; a U-shaped heating tube 402 electrically connected to one side of the heating module 401 and extending into the spiral screw 302; a battery charge and discharge module 403 installed on the other side of the heating module 401; a sealed bottom cover 404 installed with the battery charge and discharge module 403 and screwed to the bottom of the sealed tank body 101; a protective cover 405 screwed to the side of the sealed bottom cover 404 and extending to the outside of the battery charge and discharge module 403.

[0031] In the present invention, a first inclined surface 4051 is provided on the inner wall of the protective cover 405. The first inclined surface 4051 matches the inclined surface portion on the outside of the sealed bottom cover 404. A heat insulation ring 4052 sleeved on the outside of the sealed bottom cover 404 is arranged inside the protective cover 405. The heat insulation ring 4052 is arranged on the side of the first inclined surface 4051 and is arranged on the side closer to the screw 302 relative to the first inclined surface 4051.

[0032] In the automatic-adjusting extrusion pressure type sealed feeding mechanism of the present invention, when the screw 302 rotates to convey and move the compressible material, the heating module 401 arranged inside it can drive the U-shaped heating tube 402 to operate and generate heat by the energy provided by the battery charging and discharging module 403, and the heat is dissipated into the inside of the screw housing 10 to heat the compressible material inside the screw housing 10 and remove the heat inside the compressible material. At the same time, through the protective cover 405 and the sealed bottom cover 404 installed by the first inclined surface 4051, the gap size between the two joints can be reduced. Cooperating with the heat insulation ring 4052, the heat loss is minimized to ensure the effect of heating and dehumidifying the compressible material. Embodiment 2

[0033] During the actual operation of the present invention, it is found that when the compressible material conveyed inside is compressed by the fan-shaped pressure regulating plate 3043 that moves automatically and telescopically (through the conical channel 3040 formed by a plurality of fan-shaped pressure regulating plates 3043), due to the structural shape of the fan-shaped pressure regulating plate 3043, when a relatively small relative movement occurs, there will not be much gap between two adjacent fan-shaped pressure regulating plates 3043, and the compressible material will not leak. When the fan-shaped pressure regulating plate 3043 moves greatly due to the extrusion of the compressible material, the distance between two adjacent fan-shaped pressure regulating plates 3043 will become larger, and part of the compressible material will move to the outside of the fan-shaped pressure regulating plate 3043, affecting the normal restoration (position) of the fan-shaped pressure regulating plate 3043.

[0034] Specifically referring to Figure 11 and Figure 12 , the fan-shaped pressure regulating plate 3043 is set to a detachable and assembled structure. A middle pressure regulating plate 50 is arranged in the middle part of the fan-shaped pressure regulating plate 3043. Rotating heads 501 are rotatably connected to the upper and lower sides inside the middle pressure regulating plate 50. A side pressure regulating plate 502 is rotatably connected to the outside of the bottom of the rotating head 501. Another rotating head 501 is rotatably connected to the inner top of the side pressure regulating plate 502. Two adjacent middle pressure regulating plates 50 and side pressure regulating plates 502 are connected by the rotating head 501. Among them, pressure regulating springs 3042 are installed on the outside of the middle parts of the middle pressure regulating plates 50, and elastic linings 503 are adhesively adsorbed on the inner sides of the middle pressure regulating plates 50 and the side pressure regulating plates 502.

[0035] In the automatic adjustment extrusion pressure type sealing feeding mechanism of the present invention, through the sector-shaped pressure adjusting plate 3043 structure composed of a plurality of middle pressure adjusting plates 50 and side pressure adjusting plates 502, through the design of its structure (more similar to a conical structure), while ensuring the sealing performance of the contact and connection between two adjacent sector-shaped pressure adjusting plates 3043, when the middle pressure adjusting plate 50 and the side pressure adjusting plate 502 move relatively under the extrusion force of the compressible material, each part inside the middle pressure adjusting plate 50 and the side pressure adjusting plate 502 is more in contact with and fits the compressible material, improving the effect when compressing the compressible material. At the same time, when each sector-shaped pressure adjusting plate 3043 expands and moves outward under the extrusion force, there will be no gap at the connection part between two adjacent sector-shaped pressure adjusting plates 3043, and no problem of material leakage will occur.

[0036] Limited to this, any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
