Description

Technical Field

[0001] The present invention relates to the technical field of phenolic material production, and particularly to an anti-impact device for the production of phenolic resin molding materials. Background Technique

[0002] Phenolic resin molding materials are composite materials formed by using phenolic resin as the matrix and adding reinforcing materials, fillers, and modifiers through a specific molding process; they are mainly composed of a resin matrix, reinforcing materials, fillers, additives, etc., and have the characteristics of high temperature resistance, flame retardancy, corrosion resistance, etc.; during the production process of phenolic resin molding materials, raw material preparation and polycondensation reactions are first required. The polycondensation reaction is to generate a prepolymer by controlling the temperature, and then through dehydration and pulverization to obtain phenolic resin powder or granules. Subsequently, the obtained product is washed and dehydrated, and the treated phenolic resin material is poured into an injection molding machine for injection molding; During the process of feeding the phenolic resin material into the injection molding machine, in order to achieve the stability and controllability of the production process and reduce the fluctuations during the production process, the weighing of the phenolic resin material entering the injection molding machine is usually carried out to avoid affecting the quality of the product. Therefore, before feeding it into the injection molding machine, the raw materials are first fed into a screw feeder with a weighing device through a feeding device, and then fed into the injection molding machine under the screw feeding action of the screw feeder. However, when the raw materials are poured into the screw feeder with a weighing device, since there will be a certain acting force during the process of feeding the raw materials into the screw feeder with a weighing device, it will affect the weighing result. For this reason, we propose an anti-impact device for the production of phenolic resin molding materials. Summary of the Invention

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-9 , the present invention provides a technical solution: an anti-impact device for the production of phenolic resin molding materials. The present invention makes corresponding improvements to the technical problems in the background technology, and combines the attached Figure 1As shown, it includes a first steel sleeve 5 connected to the feeding device 1. A screw feeder 3 is arranged below the first steel sleeve 5. The screw feeder 3 is placed on the weighing mechanism 2, that is, the weight of the screw feeder 3 is certain, and the discharge end of the screw feeder 3 is communicated with the feeding port of the injection molding mechanism 4. A second steel sleeve 6 is threadedly connected to the first steel sleeve 5, and the second steel sleeve 6 does not contact the feeding end of the screw feeder 3. The above-mentioned devices should be fixedly installed on the bracket. However, since the bracket is prior art, it is not described in the present invention. A buffer panel 51 is fixedly installed inside the first steel sleeve 5, and a discharge hole 52 is arranged on the buffer panel 51. Referring to the attached Figure 2 As shown, the axis of the discharge hole 52 does not coincide with the axis of the discharge end of the feeding device 1. Therefore, the raw materials in the feeding device 1 flow out from its discharge end and fall onto the buffer panel 51. The buffer panel 51 plays a buffering role in the falling of the raw materials in the feeding device 1. A partition 61 is fixedly installed inside the second steel sleeve 6, and an output hole 62 is arranged on the partition 61. The axis of the output hole 62 does not coincide with the axis of the discharge hole 52. A plurality of scraping parts 7 are arranged inside the first steel sleeve 5 for feeding the phenolic resin material below the feeding port of the first steel sleeve 5 into the discharge hole 52; Referring to the attached Figure 2 and the attached Figure 5 As shown, a servo motor 63 is fixedly installed at the bottom of the second steel sleeve 6. The output end of the servo motor 63 is fixedly installed with a rotating shaft body 64. The end of the rotating shaft body 64 sequentially penetrates through the partition 61 and the buffer panel 51 and extends into the first steel sleeve 5. The rotating shaft body 64 is rotatably connected to both the partition 61 and the buffer panel 51. Referring to the attached Figure 7 As shown, a support sleeve 53 is fixedly installed on the buffer panel 51. A cavity 54 is formed in the support sleeve 53, and an annular gear row 55 is fixedly installed in the cavity 54. Referring to the attached Figure 5 As shown, a connecting sleeve 65 is fixedly installed at the end of the rotating shaft body 64, and the connecting sleeve 65 is rotatably connected to the support sleeve 53; a plurality of scraping parts 7 are arranged on the connecting sleeve 65, and a conveying unit 8 is arranged on the rotating shaft body 64; As a further limitation in the present invention, the scraping part 7 includes a steel scraping frame 71 fixedly connected to the connecting sleeve 65. Referring to the attached Figure 4 As shown, there is a height difference between the two side walls of the steel scraping frame 71, that is, the height of one side is higher than that of the other side. Therefore, when the steel scraping frame 71 rotates with the rotating shaft body 64 under the action of the connecting sleeve 65, the side with a relatively higher height of the steel scraping frame 71 first contacts the raw materials on the buffer panel 51. Then, under the action of the steel scraping frame 71, the raw materials on the buffer panel 51 (that is, directly below the discharge end of the feeding device 1) are transferred into the discharge hole 52.

[0019] In the actual application process, due to parameter design or operation problems in the production process, the phenolic resin material particles often show a situation of particle size differentiation. When some phenolic resin material particles with larger particle sizes participate in the injection molding process, because the large-particle phenolic resin material has a small specific surface area and a slow heating rate, it is easy to cause melting lag, form a temperature difference with the surrounding small particles, and thus cause local unmelted residue or carbonization; a large difference in particle size is also likely to cause inconsistent shrinkage rates when the melt cools, unbalanced internal stress distribution in the product, and easy warping and deformation. Therefore, based on this, the following design is carried out in the present invention: A filter plate 56 is fixedly installed in the discharge hole 52 to filter the phenolic resin material through the filter plate 56. On the side with a relatively high height of the steel scraping plate frame 71, a plurality of filter rollers 72 rotatably connected thereto are also installed. The plurality of filter rollers 72 are arranged at equal intervals along the axis direction of the rotating shaft body 64. The end of the filter roller 72 is located inside the steel scraping plate frame 71. A meshing gear 73 is installed on each filter roller 72, and the meshing gears 73 mesh with each other. The meshing gears 73 are located inside the steel scraping plate frame 71. Further explanation, in combination with the attached Figure 3 and attached Figure 4 As shown, there is a gap between the filter rollers 72. Qualified phenolic resin materials can enter the inside of the steel scraping plate frame 71 through the filter rollers 72, while the phenolic resin materials with large particle sizes will be blocked on the surface of the filter rollers 72 to prevent the phenolic resin materials with large particle sizes from entering the inside of the steel scraping plate frame 71; an extension shaft body 74 is fixedly installed at the end of one of the filter rollers 72, and the end of the extension shaft body 74 penetrates through the connecting sleeve 65 and extends into the cavity 54. The extension shaft body 74 is rotatably connected to the inner wall of the connecting sleeve 65. One end of the extension shaft body 74 located inside the cavity 54 is also fixedly installed with a driving gear 75, and the driving gear 75 is in a meshing state with the annular tooth row 55; And a filter chamber 57 is also provided on the buffer panel 51, and a plurality of flexible rollers 58 rotatably connected to its inner wall are installed in the filter chamber 57. The discharge end of the filter chamber 57 is externally connected to the first steel sleeve 5. The bottom of the buffer panel 51 is also fixedly installed with a collection chamber 59 threadedly connected thereto. The plurality of flexible rollers 58 are arranged obliquely downward in the filter chamber 57. Then, when the steel scraping plate frame 71 drives the raw material through the filter plate 56, because there is a large amount of raw material on the surface of the steel scraping plate frame 71, the phenolic resin materials with large particle sizes may carry some qualified phenolic resin materials during movement, which is likely to cause the qualified phenolic resin materials to leave the filter plate 56 before contacting the filter plate 56. Therefore, after the steel scraping plate frame 71 leaves the filter plate 56, it will move to the filter chamber 57. At this time, the phenolic resin materials on the surface of the steel scraping plate frame 71 fall into the filter chamber 57 and contact the obliquely downward flexible rollers 58. In combination with the attached Figure 6As shown, there is a gap between the flexible rollers 58 to block the phenolic resin material with large particle sizes. The qualified phenolic resin material will pass through the flexible rollers 58 and fall into the collection chamber 59, while the phenolic resin material with large particle sizes will flow out from the inside of the first steel sleeve 5 along the trajectory of the flexible rollers 58. Workers can place a collection bucket below the first steel sleeve 5 in advance to collect the flowing phenolic resin material with large particle sizes. After the phenolic resin material with large particle sizes is collected to a certain extent, it can be uniformly crushed; Furthermore, in the present invention, the steel scraping plate frame 71 is used to convey the raw materials that fall onto the buffer panel 51 and are directly below the discharge end of the feeding device 1. During the conveying process, under the action of the filtering roller 72, the screening work of the phenolic resin material is carried out, so that the qualified phenolic resin material enters the steel scraping plate frame 71, and the phenolic resin material with large particle sizes is blocked outside the steel scraping plate frame 71. Thus, through the filter plate 56, the qualified phenolic resin material flows out from the discharge hole 52, and under the action of the filtering chamber 57 and the flexible rollers 58, the phenolic resin material is further screened to avoid the phenolic resin material with large particle sizes flowing out of the first steel sleeve 5 with some qualified phenolic resin material. Furthermore, through the structural design of the present invention, it can effectively prevent the phenolic resin material participating in the injection molding process from having a large difference in particle size, thereby avoiding affecting the produced molded products.

[0020] During the actual production process, when the phenolic resin materials with large differences in particle size are mixed and fed, it will not only affect the weighing result and injection molding quality, but also easily cause fluctuations in the bulk density at the discharge end of the feeding device 1, that is, the large particles are stuck and then suddenly released, resulting in a sudden increase in the feeding amount. When there is a sudden increase in the feeding amount at the discharge end of the feeding device 1, then there will be more raw materials accumulated on the buffer panel 51, so that the amount of raw materials transferred by the steel scraping plate frame 71 each time will increase accordingly, and then the amount of materials entering the screw feeder 3 will increase, increasing the load on the screw feeder 3 and the injection molding mechanism 4. Based on this, the present invention makes the following design to ensure that the amount of materials entering the screw feeder 3 each time remains within the normal range; Inside the steel sleeve two 6, a conveying unit 8 is further provided, and the conveying unit 8 is used to convey the raw materials on the partition plate 61 to the output hole 62. The conveying unit 8 in the present invention includes a frame 81 fixedly installed on the rotating shaft body 64, and a ring sleeve 82 is also fixedly installed on the frame 81. A receiving sleeve 83 is fixedly installed inside the ring sleeve 82. The aperture of the feeding end of the receiving sleeve 83 is larger than the aperture of the discharging hole 52. The inside of the receiving sleeve 83 is hollow, and the bottom of the receiving sleeve 83 is in contact with the partition plate 61. An annular chamber 84 is formed between the outer wall of the receiving sleeve 83 and the inner wall of the ring sleeve 82. An annular receiving plate 85 is installed inside the annular chamber 84, and the cross-section of the annular receiving plate 85 is a right-angled trapezoid. A plurality of sliding shafts 86 are fixedly installed at the bottom of the annular receiving plate 85, and the ends of the sliding shafts 86 penetrate through the bottom of the annular chamber 84 and extend outside the ring sleeve 82. An annular iron sheet 87 fixedly connected to the ends of the plurality of sliding shafts 86 is arranged below the ring sleeve 82. A return spring 88 is sleeved on each sliding shaft 86, and the return spring 88 is used to connect the annular receiving plate 85 and the bottom of the annular chamber 84. The aperture of the feeding end of the receiving sleeve 83 is larger than the aperture of the discharging hole 52. A plurality of through grooves 89 communicating with the inside of the annular chamber 84 are further provided inside the receiving sleeve 83, and an arc magnet 66 is fixedly installed on the partition plate 61. The arc magnet 66 is located on the movement track of the annular iron sheet 87; it should be noted that some phenolic resin materials can be placed on the annular receiving plate 85. When a large particle size jamming occurs at the discharging end of the feeding device 1, then before the sudden release, the raw materials flowing out may be less than the normal flowing out raw materials. Therefore, by placing some phenolic resin materials on the surface of the annular receiving plate 85, it can be supplemented into the receiving sleeve 83 in this case; Specifically, in the actual production process, the feeding device 1 conveys the materials to the inside of the first steel sleeve 5, that is, on the buffer panel 51, through its discharge end. During this process, the servo motor 63 remains turned on, and the output end of the servo motor 63 drives the rotating shaft body 64 to rotate. The rotating shaft body 64 drives the steel scraping plate frame 71 to rotate through the connecting sleeve 65. During the rotation of the steel scraping plate frame 71, the raw materials on the buffer panel 51 will be transferred to the discharge hole 52. During this process, the filtering roller 72 will screen the phenolic resin material, enabling the qualified phenolic resin material to enter the steel scraping plate frame 71, while the phenolic resin material with large particle size is blocked outside the steel scraping plate frame 71. Moreover, during the process of the steel scraping plate frame 71 transferring the surface raw materials, the extension shaft body 74 on one of the filtering rollers 72 will drive the driving gear 75 to perform a circular motion along the annular tooth row 55, and the driving gear 75 meshes with the annular tooth row 55. Then, under the action of the annular tooth row 55, the driving gear 75 drives the meshing gear 73 to rotate through the extension shaft body 74, and the meshing gears 73 mesh with each other. Thus, multiple filtering rollers 72 rotate. On the one hand, the rotation of the filtering rollers 72 can effectively prevent the raw materials with particle sizes close to the gap between the filtering rollers 72 from getting stuck between the filtering rollers 72. On the other hand, the rotation of the filtering rollers 72 can accelerate the flow of the raw materials on the surface of the steel scraping plate frame 71 to accelerate the screening of the raw materials.Subsequently, under the action of the steel scraper frame 71, the raw materials move to the discharge hole 52, and under the action of the filter plate 56, the large-particle-size raw materials are blocked. The raw materials with qualified particle sizes fall into the material receiving sleeve 83 through the discharge hole 52, and the large-particle-size raw materials will move to the filtration chamber 57 along with the steel scraper frame 71. At this time, the phenolic resin material on the surface of the steel scraper frame 71 falls into the filtration chamber 57 and contacts the flexible roller 58 in an inclined downward state. There is a gap between the flexible rollers 58 to block the large-particle-size phenolic resin material, and the qualified phenolic resin material will fall into the collection chamber 59 through the flexible roller 58, while the large-particle-size phenolic resin material will flow out from the inside of the steel sleeve 1 5 along the track of the flexible roller 58. After the material receiving sleeve 83 receives the raw materials, the raw materials will fill the space inside the material receiving sleeve 83. If there is too much raw material, it will fall into the annular chamber 84 between the material receiving sleeve 83 and the annular sleeve 82 through the through groove 89. That is, the position where the through groove 89 is designed is the volume limit of the raw materials injected into the screw feeder 3 each time. Therefore, when there is more raw material, it will fall into the annular chamber 84 through the through groove 89. Subsequently, under the action of the frame 81, the rotating shaft body 64 drives the annular sleeve 82 to perform a circular motion, that is, the material receiving sleeve 83 moves synchronously with it under the action of the annular sleeve 82. During the movement, the annular iron sheet 87 will pass by the arc-shaped magnet 66, and the arc-shaped magnet 66 generates a repulsive force on the annular iron sheet 87. That is, the annular iron sheet 87 drives the annular material receiving plate 85 to perform an upward movement through the sliding shaft body 86. During this process, the return spring 88 is in a stretched state, and the raw materials on the annular material receiving plate 85 will move upward synchronously with it, causing the raw materials to rise to the through groove 89. If the raw materials in the material receiving sleeve 83 are filled to the through groove 89, at this time, the raw materials in the annular material receiving plate 85 will not fall into the material receiving sleeve 83 through the through groove 89. However, if the raw materials in the material receiving sleeve 83 are not filled to the through groove 89, then the raw materials in the annular material receiving plate 85 will fall into the material receiving sleeve 83 through the through groove 89 to supplement the raw materials in the material receiving sleeve 83, ensuring that the raw materials in the material receiving sleeve 83 are within a certain range each time. Subsequently, the material receiving sleeve 83 moves towards the output hole 62. During the process of approaching the output hole 62, the annular iron sheet 87 leaves above the arc-shaped magnet 66, and then under the action of the return spring 88, the annular material receiving plate 85 returns to its initial position, that is, the raw materials on the annular material receiving plate 85 are not located at the through groove 89. When the material receiving sleeve 83 moves to the output hole 62, the raw materials inside it will fall into the screw feeder 3 through the output hole 62. And in the present invention, the buffer panel 51 inside the steel sleeve 1 5 and the partition plate 61 inside the steel sleeve 2 6 play a buffering role for the phenolic resin material participating in the forming reaction and being weighed, effectively absorbing the impact force of the falling raw materials, avoiding equipment damage or measurement error caused by the direct impact of the raw materials on the weighing mechanism 2, so as to play an anti-impact role and reduce the influence on the weighing mechanism 2 when the raw materials directly fall;The raw materials entering the spiral feeder 3 will be output into the injection molding mechanism 4 under the action of spiral transportation for injection molding work.
