Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying, in particular to an automatic adjustment extrusion pressure type sealing feeding mechanism. BACKGROUND

[0002] The compressible material refers to a material that significantly reduces the volume and increases the density under the action of external force, which is suitable for straw compression in industrial compression and other fields, and has the advantages of reducing transportation frequency, etc. When the compressible material is compressed, the compressible material needs to be driven to move and be moved to the inside of the compression structure to realize the compression operation.

[0003] However, the feeding device has the following defects in specific use:

[0004] 1. When the existing compressible material completes the material conveying operation through the sealing feeding mechanism, in order to avoid the entry of external gas into the inside of the compressible material and affect the storage time, a sealed feeding and conveying system is needed. However, the conventional feeding device is generally arranged in a multi-stage plug seal and intermittent feeding mode, which is easy to cause the feeding device (system) to be complex and have a high failure rate. In particular, the connecting part position of the two device tanks is easy to cause bridging phenomenon, which hinders the normal flow and conveying of the material. At the same time, when the conveyed material is compressed, the compressed material is difficult to cooperate and resist the compression material structure, and it is difficult to compress the compressible material with different densities, and the compression effect of the material is poor;

[0005] 2. When the existing compressible material is compressed by the compression structure inside the feeding device, due to the different gaps and densities between the compressible materials conveyed into the inside of the feeding device, the compression material structure is difficult to tightly resist the compressible material to realize the compression operation of the compressible material. At the same time, corresponding to the compressible material with high humidity, it will hinder the close combination of the material, cause the compression density to decrease, and affect the compactness and quality of the product. Moreover, after compression, the material with high humidity is more likely to swell and shrink, causing the compression size to be unstable. SUMMARY

[0052] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts should belong to the scope of protection of the present application. Embodiment one

[0055] The working principle is as follows: the spiral feeding extrusion mechanism 30 composed of the plurality of sealing tank bodies 101 can make the compressible material normally and smoothly move into the tapered channel 3040 in the inside of the extrusion pressure regulating structure 304 through the conveying force generated by the rotation operation of the main shaft 301 and the spiral screw 302 driven by the operation of the servo driving source 20, and automatically compress the compressible material through the structure of the tapered channel 3040 and move the compressed material to one side of the emptying channel 103. When the main shaft 301 operates, the oscillation scattering assembly 303 can also operate to scatter the compressible material moving into the inside of the entering channel 102, reduce the probability of the compressible material sticking together, and ensure that the compressible material is more easily heated and dehumidified by the assembled heating assembly 40 after entering the inside of the spiral shell body 10, thereby improving the effect of the compressed material. In addition, the scattered compressible material has better compression effect when being compressed, thereby ensuring the quality of the compressed material.

[0056] In the present application, the servo driving source 20 is preferably a servo motor.

[0057] The inside of the entering channel 102 is internally provided with assembly supports 1021, and the top of the assembly supports 1021 is provided with material guiding supports 1022, and the two assembly supports 1021 are rotationally connected with oscillation scattering assemblies 303.

[0058] With reference to Figure 5 and Figure 7 , the oscillation scattering assembly 303 comprises: a transmission belt 3031 connected outside the main shaft 301 through a synchronous wheel; a driving rod 3032 connected inside the transmission belt 3031 and extending into the inside of the entering channel 102; a deflection connecting block 3033 connected with the driving rod 3032 and movably arranged in the inside of the entering channel 102; an oblique oscillation rod 3034 rotationally connected with the deflection connecting block 3033; a lifting movable block 3035 movably arranged outside the oblique oscillation rod 3034; lifting sliding blocks 3036 rotationally connected on the left and right sides of the lifting movable block 3035; vertical guide rods 3037 slidingly connected with the lifting sliding blocks 3036; and material feeding supports 3038 arranged on the upper and lower sides of the vertical guide rods 3037.

[0059] In the present application, the deflection connecting block 3033 is provided with two, and the two deflection connecting blocks 3033 are movably connected with the oblique oscillation rod 3034, wherein the outside of the oblique oscillation rod 3034 is provided with material oscillation blades 30341, and the material oscillation blades 30341 are movably arranged between the two material feeding supports 3038; the inside of the material feeding support 3038 is provided with a discharging through hole 30381 for material movement and discharge, and the material feeding support 3038 is rotationally connected with the side of the assembly support 1021, wherein the discharging through hole 30381 is consistent with the through hole provided in the inside of the assembly support 1021, and the discharging through hole 30381 is arranged on the side of the vertical guide rod 3037.

[0060] When the main shaft 301 rotates, the outer side of the main shaft 301 drives the transmission belt 3031 connected by the synchronous wheel to operate, and the inner side of the transmission belt 3031 drives the driving rod 3032 connected by the synchronous wheel to rotate. At this time, the driving rod 3032 rotates and drives the deflection connecting block 3033 installed at the bottom of the driving rod 3032 to rotate, so that the oblique oscillation rod 3034 and the lifting movable block 3035 connected to the side of the deflection connecting block 3033 move on the side of the lifting slide block 3036 and rotate in the deflection direction. At the same time, the lifting slide block 3036 can move up and down on the outer side of the vertical guide rod 3037, that is, the oblique oscillation rod 3034 rotates and moves up and down at the same time, which improves the effect of the oblique oscillation rod 3034 and the material oscillation blade 30341 on the material oscillation and dispersion. The feeding support 3038 can be reversely rotated by a certain angle due to the operation of the oblique oscillation rod 3034, which can reduce the probability of material accumulation and adhesion on the feeding support 3038.

[0061] With reference to Figure 5 , Figure 8 and Figure 9 , the extrusion pressure regulating structure 304 includes: a spring mounting pin 3041 mounted on the inner wall of the sealing tank 101; a pressure regulating spring 3042 connected with the spring mounting pin 3041; a fan-shaped pressure regulating plate 3043 mounted at the bottom of the pressure regulating spring 3042; a feeding sealing ring 3044 mounted on one side of the feeding port of the fan-shaped pressure regulating plate 3043 and located inside the sealing tank 101; a discharging sealing ring 3045 mounted on one side of the discharging port of the fan-shaped pressure regulating plate 3043 and located inside the sealing tank 101; and an air bag 3046 mounted on the side of the feeding sealing ring 3044 and the discharging sealing ring 3045 and abutting against the outer side of the fan-shaped pressure regulating plate 3043, wherein the side of the air bag 3046 in contact with the fan-shaped pressure regulating plate 3043 is connected by an elastic adhesive material to remove the gap at the connection between the air bag 3046 and the fan-shaped pressure regulating plate 3043.

[0062] In the present application, the spring mounting pin 3041, the pressure regulating spring 3042 and the fan-shaped pressure regulating plate 3043 are provided in plurality, and the plurality of fan-shaped pressure regulating plates 3043 form a tapered channel 3040, wherein the plurality of fan-shaped pressure regulating plates 3043 abut together in a scale-like manner, there is no gap at the connection part of the adjacent two fan-shaped pressure regulating plates 3043, and the pressure regulating spring 3042 is arranged obliquely.

[0063] In the automatic adjusting extrusion pressure type sealing feeding mechanism of the present application, when the compressible material enters the inside of the conical passage 3040 formed by the plurality of fan-shaped pressure adjusting plates 3043, it will extrude the abutting fan-shaped pressure adjusting plates 3043 and the pressure adjusting spring 3042 and drive the fan-shaped pressure adjusting plates 3043 to move. At this time, through the elastic force and the elastic coefficient of the pressure adjusting spring 3042, extrusion pressure will be generated on the compressible material inside the fan-shaped pressure adjusting plate 3043, and the structure of the conical passage 3040 is matched to complete the automatic extrusion operation of the compressible material. The design of the feeding sealing ring 3044 and the discharging sealing ring 3045 matches the structure of the sealing tank body 101 arranged on the left and right sides, and the compressible material conveying will not be hindered; the design of the air bag 3046 matches the pressure adjusting spring 3042 to ensure that the plurality of fan-shaped pressure adjusting plates 3043 can be tightly abutted together, avoiding the generation of gaps in the plurality of fan-shaped pressure adjusting plates 3043 while improving the compression performance.

[0064] With reference to the drawings Figure 10 The assembled heating assembly 40 includes: a heating module 401 movably arranged at the bottom of the spiral screw 302; a U-shaped heating pipe 402 electrically connected to one side of the heating module 401 and extending into the inside of the spiral screw 302; a battery charging and discharging module 403 mounted on the other side of the heating module 401; a sealing bottom cover 404 mounted with the battery charging and discharging module 403 and mounted on the bottom of the sealing tank body 101 by screws; and a protective cover 405 mounted on the side of the sealing bottom cover 404 and extending to the outside of the battery charging and discharging module 403 by screws.

[0065] In the present application, a first inclined surface 4051 is arranged at the inner wall of the protective cover 405, the first inclined surface 4051 matches the inclined surface portion on the outside of the sealing bottom cover 404, a heat blocking ring 4052 is arranged on the outside of the sealing bottom cover 404 in the inside of the protective cover 405, the heat blocking ring 4052 is arranged on the side of the first inclined surface 4051, and the heat blocking ring 4052 is arranged close to the side of the spiral screw 302 relative to the first inclined surface 4051.

[0066] In the automatic adjusting extrusion pressure type sealing feeding mechanism of the present application, when the spiral screw 302 rotates to convey and move the compressible material, the heating module 401 arranged inside can drive the U-shaped heating pipe 402 to operate to generate heat by the energy provided by the battery charging and discharging module 403, and the heat is dissipated to the inside of the spiral outer shell 10 to heat and treat the compressible material in the inside of the spiral outer shell 10 to remove the heat in the inside of the compressible material. At the same time, the protective cover 405 and the sealing bottom cover 404 installed through the first inclined surface 4051 can reduce the gap size between the connection parts, and the heat blocking ring 4052 can maximize the heat loss to ensure the heating and dehumidifying effect of the compressible material. Example Two

[0067] The present application is found in actual operation, when the compressible material transported inside is compressed by the automatic telescopic active sector pressure plate 3043 (the conical passage 3040 formed by multiple sector pressure plates 3043), due to the structural shape of the sector pressure plate 3043, when a small relative movement occurs, the gap between the adjacent two sector pressure plates 3043 will not be large, and the compressible material will not leak. When the sector pressure plate 3043 moves greatly due to the extrusion of the compressible material, the distance between the adjacent two sector pressure plates 3043 will increase, and part of the compressible material will move to the outside of the sector pressure plate 3043, affecting the normal recovery (position) of the sector pressure plate 3043.

[0068] With reference to Figure 11 and Figure 12 The sector pressure plate 3043 is arranged in a detachable structure, the middle part of the sector pressure plate 3043 is provided with a middle pressure plate 50, the upper and lower sides inside the middle pressure plate 50 are rotatably connected with rotating heads 501, the outer side of the bottom of the rotating head 501 is rotatably connected with a side pressure plate 502, the inner top of the side pressure plate 502 is rotatably connected with another rotating head 501, the adjacent two middle pressure plates 50 and side pressure plates 502 are connected through the rotating head 501, wherein the outer side of the middle part of the middle pressure plate 50 is provided with a pressure spring 3042, and the inner side of the middle pressure plate 50 and the side pressure plate 502 is adhered and adsorbed with an elastic gasket 503.

[0069] In the automatic adjustment extrusion pressure type sealing feeding mechanism of the present application, the sector pressure plate 3043 structure formed by multiple middle pressure plates 50 and side pressure plates 502 can be designed (more similar to a conical structure) to ensure the abutment and connection sealing of the adjacent two sector pressure plates 3043, and when the middle pressure plate 50 and the side pressure plate 502 move relatively due to the extrusion force of the compressible material, the inner side of the middle pressure plate 50 and the side pressure plate 502 is more abutted and fitted with the compressible material, improving the effect of compressing the compressible material. When each sector pressure plate 3043 moves outwardly and expands under the extrusion force, the connecting part of the adjacent two sector pressure plates 3043 will not have a gap, and the problem of material leakage will not occur.

[0070] Therefore, any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
