Description
Technical Field
[0001] The present application relates to the technical field related to resin processing machinery, and in particular to an epoxy resin crushing and cleaning device. Background Art
[0002] Epoxy resin is a widely used thermosetting resin mainly composed of epoxy groups and hardeners. It has high strength, chemical corrosion resistance and good electrical insulation properties.
[0003] During the production process, solid epoxy resin needs to be crushed. At present, when solid epoxy resin is crushed, particles and powders of different sizes are mixed together at the same time, resulting in increased crushing intensity. At the same time, in order to ensure that the particle size of the crushed epoxy resin output is relatively consistent, the existing method mainly uses the crushed epoxy resin to pass through a screen and then transport it back to the crushing mechanism for secondary crushing. The increase in mechanisms leads to increased costs. In addition, due to the increase in mechanisms, there will be an increase in dead angles for transportation and crushing, resulting in reduced crushing efficiency. Summary of the invention

The inner side of the conveying belt is fixedly connected to a fixed base located in the storage chamber, and the fixed base realizes quantitative conveying of materials to the crushing roller; the filter plate is fixedly installed on the outer side of the crushing box, and the inner side of the filter plate is slidably connected to the outer side of the conveying belt; the discharge port is opened on the outer side of the conveying belt and is located between adjacent fixed bases. When the fixed base follows the conveying belt downward, the small particle materials floating in the storage chamber are output to the outside through the discharge port and the filter plate; the feed pipe is fixed on the surface of the crushing box to supply airflow and raw materials to the storage chamber.
[0006] Furthermore, the angle between the surface of the fixed base and the inner side of the conveyor belt is 45-75 degrees.
[0007] Furthermore, there are multiple fixed bases, and the multiple fixed bases are arranged equidistantly on the inner side of the conveyor belt.
[0008] Furthermore, a movable push plate is movably sleeved inside the fixed base, and the bottom end of the movable push plate is fixedly connected to an ejection spring located in the inner cavity of the fixed base, the ejection spring is fixed on the inner side of the conveying ring belt, and a driving head is fixedly installed on the end of the movable push plate.
[0009] Furthermore, the driving head has a cylindrical shape.
[0010] Furthermore, a supporting base is movably installed on the inner side of the crushing box, and a crushing cutter located on one side of the driving head is fixedly installed on the outer side of the supporting base. When the fixed base drives the driving head upward, the driving head is blocked by the crushing cutter and retracted into the fixed base to achieve controllable feeding amount.
[0011] Furthermore, a fixing bolt located outside the crushing box is fixedly mounted on the end of the supporting frame to achieve locking of the supporting frame.
[0012] Furthermore, it also includes: an air jet port, which is opened on the outer side of the driving head and a one-way air valve is fixedly installed in the air jet port, and the one-way air valve realizes one-way transportation of the airflow in the inner cavity of the driving head to the outside; an air inlet, which is opened on the side of the conveying ring belt and communicates with the inner cavity of the fixed base, and a one-way air valve is fixedly installed on the outer side of the conveying ring belt for one-way transportation of the airflow in the air inlet to the inner cavity of the fixed base; an air release groove, which is opened on the surface of the crushing box to realize the transportation of external airflow to the air inlet.

[0015] The present invention has the following beneficial effects:
[0016] The present application provides an epoxy resin crushing and cleaning device, in which a fixed base is arranged in a conveying ring belt, and quantitative feeding is achieved by driving the fixed base to rotate according to the conveying ring belt. Since the fixed base is arranged obliquely, the air flow in the material storage chamber is output to the filter plate through the fixed base during the downward movement of the fixed base, so that the small particles of epoxy resin crushed by the crushing roller move toward the filter plate, and small particles of epoxy resin are obtained after being filtered by the filter plate. The retained large particles of epoxy resin are conveyed to the crushing roller again along with the fixed base, so that the large particles of epoxy resin are crushed for the second time, thereby achieving the effect of particle separation.
[0017] At the same time, since the conveyor belt is arranged in a ring shape, and the two ends of the conveyor belt correspond to the ring grooves opened on the inner side of the crushing box, the conveyor belt rotates along the ring grooves. Therefore, in the process of conveying materials, the fixed base will convey all the materials retained in the storage chamber upward, and there is no dead angle position, which avoids the problem of material accumulation and residue, and finally achieves the purpose of conveying materials without dead angles.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0028] Embodiment 1
[0029] See also Figure 1 and Figure 2 A power motor 2 is fixed on the back of the crushing box 1, and the power motor 2 rotates the driving shaft 3 on the top of the crushing box 1 through a belt. A material storage chamber 100 is opened inside the crushing box 1, and a crushing roller 7 located in the material storage chamber 100 is fixedly installed on the outside of the driving shaft 3. There are two crushing rollers 7. A pair of active gear plates 5 and a driven gear plate 6 are movably installed on the inside of the crushing box 1, and the active gear plate 5 is coaxially fixed with the driving shaft 3. Therefore, when the driving shaft 3 drives the crushing roller 7 and the active gear plate 5 to rotate, the active gear plate 5 causes the driven gear plate 6 to rotate synchronously, thereby realizing the relative rotation between the two crushing rollers 7, and finally crushing the epoxy resin between the two crushing rollers 7.
[0030] A conveyor belt 11 located in the material storage chamber 100 is movably installed on the inner side of the crushing box 1, and the outer side of the conveyor belt 11 slides relatively with the inner side of the crushing box 1. A fixed base 12 located in the material storage chamber 100 is fixedly connected to the inner side of the conveyor belt 11. There are multiple fixed bases 12, and the multiple fixed bases 12 are equidistantly arranged on the inner side of the conveyor belt 11. Since the spacing between the fixed bases 12 is consistent, in this embodiment, the fixed base 12 contacts the active toothed disc 5 and makes the conveyor belt 11 rotate synchronously with the active toothed disc 5, so as to Figure 2It can be seen that the angle between the surface of the fixed base 12 and the inner side of the conveying belt 11 is between 45 and 75 degrees. Therefore, when the conveying belt 11 drives the fixed base 12 upward, the fixed base 12 is arranged tilted upward, so that the material in the storage chamber 100 can be transported to the top of the crushing roller 7 through the fixed base 12. In order to ensure the stability of the fixed base 12 in transportation, the two ends of the fixed base 12 are fitted with the inner side of the crushing box 1. In this way, during the upward movement of the fixed base 12, a chamber for holding the material is formed based on the top of the fixed base 12, the inner side of the conveying belt 11 and the inner side of the crushing box 1, thereby realizing the transportation of the material.
[0031] In order to facilitate the discharge of materials, a filter plate 8 is fixedly installed on the outside of the crushing box 1, and the inner side of the filter plate 8 is slidably connected to the outer side of the conveying ring belt 11. The filter plate 8 is in the downward position of the conveying ring belt 11. Figure 2 It can also be seen that the shape of the filter plate 8 is approximately L-shaped. When the crushing roller 7 crushes the epoxy resin raw material, the raw material will fall to the bottom of the storage chamber 100 due to gravity. When the fixed base 12 is downward, the inclination direction is downward, and a discharge port 110 located between the fixed base 12 is opened on the outer side of the conveying ring belt 11 to ensure that when the conveying ring belt 11 drives the fixed base 12 downward, since the filter plate 8 and the discharge port 110 are connected, the airflow in the storage chamber 100 will be output outward through the fixed base 12, and the small particles of epoxy resin falling downward from the crushing roller 7 will move toward the direction of the filter plate 8, and the small particles of epoxy resin will be filtered out through the filter plate 8, and the large particles of epoxy resin will fall to the bottom of the storage chamber 100. As the fixed base 12 moves upward again, the epoxy resin material is quantitatively transported to the direction of the crushing roller 7, thereby realizing continuous quantitative feeding.
[0032] Combination Figure 3 It can be seen that a feed pipe 101 connected to the material storage chamber 100 is fixedly installed on the surface of the crushing box 1, and the raw material is fed into the material storage chamber 100 through the feed pipe 101 to realize the supply of materials. At the same time, as the conveyor belt 11 descends, the airflow will be transported outward through the filter plate 8, and the airflow in the material storage chamber 100 is supplemented according to the feed pipe 101, thereby realizing the stability of the airflow in the material storage chamber 100.
[0033] When in use, the epoxy resin raw material is injected into the storage chamber 100 through the feed pipe 101, and the raw material falls to the bottom of the storage chamber 100 due to gravity. At the same time, the power motor 2 drives the drive shaft 3 to rotate, so that the crushing rollers 7 rotate relative to each other. At the same time, the conveying belt 11 rotates counterclockwise, and the direction is referenced Figure 2 At this time, the downward fixed base 12 will cause the airflow in the storage chamber 100 to be output to the filter plate 8, and the small particle raw materials input into the feed pipe 101 will be blown by the airflow to move toward the filter plate 8 to achieve the initial screening.
[0034] Afterwards, as the fixed base 12 continues to rotate, the fixed base 12 transports the raw materials at the bottom of the storage chamber 100 upward until the raw materials are poured between the crushing rollers 7, thereby crushing the raw materials. Since the shape of the fixed base 12 and the distance between two adjacent ones are certain, the amount of raw materials transported upward each time is constant, thereby achieving the purpose of quantitative feeding.
[0035] The crushed material will move to the bottom of the storage chamber 100 due to gravity. At the same time, the fixed base 12 descending along with the conveying ring belt 11 will make the airflow in the storage chamber 100 be transported to the filter plate 8, thereby attracting the crushed small particles of raw materials in the direction of the filter plate 8 until the small particles of raw materials are discharged from the filter plate 8, avoiding the mixing of large and small raw materials at the bottom of the storage chamber 100, which leads to the increase of the crushing strength of the crushing roller 7.
[0036] Embodiment 2
[0037] On the basis of the first embodiment, in order to further enhance the airflow blowing in the direction of the filter plate 8, please refer to Figure 4 and Figure 5 A movable push plate 13 is movably sleeved inside the fixed base 12, and the bottom end of the movable push plate 13 is fixedly connected to an ejection spring 120 located in the inner cavity of the fixed base 12. The ejection spring 120 is fixed to the inner side of the conveying ring belt 11. Under the action of the elastic force of the ejection spring 120, the movable push plate 13 always has a tendency to push outward. A driving head 14 is fixedly installed at the end of the movable push plate 13. The driving head 14 is cylindrical in shape, and the driving head 14 can just be stuck into the outer side of the active gear disc 5, so that during the continuous rotation of the active gear disc 5, the active gear disc 5 and the driving head 14 will fit together. The fixed base 12 drives the conveyor belt 11 to rotate. In order to prevent the driving head 14 from being unable to move normally due to unilateral force during the rotation of the active toothed disc 5, in this embodiment, two active toothed discs 5 are provided, and the two active toothed discs 5 are respectively located at the two ends of the crushing roller 7, so that the active toothed disc 5 can stably transmit the drive head 14. In this second embodiment, due to the extension of the movable push plate 13, the fixed base 12 can gather more airflow to be transported to the filter plate 8 during the downward movement of the conveyor belt 11, which makes it easier for small particles floating in the storage chamber 100 to be discharged outward.
[0038] Embodiment 3
[0039] Based on the second embodiment, see Figure 4-Figure 6A support frame 9 is movably installed on the inner side of the crushing box 1, and a crushing cutter 10 located on one side of the driving head 14 is fixedly installed on the outer side of the support frame 9. In this embodiment, a fixing bolt located on the outer side of the crushing box 1 is fixedly installed through the end of the support frame 9, so that the support frame 9 can be locked at a fixed angle. When the fixed base 12 drives the movable push plate 13 and the driving head 14 to move upward, the driving head 14 will be blocked by the crushing cutter 10 and move toward the fixed base 12, so that the protruding length of the movable push plate 13 is reduced, and the feeding amount of the fixed base 12 can be achieved by controlling the deflection angle of the support frame 9, so that the feeding amount of the fixed base 12 can be controlled.
[0040] On the basis of the above, an air jet 140 is opened on the outer side of the driving head 14, and a one-way air valve 16 is fixedly installed in the air jet 140. The one-way air valve 16 realizes the one-way transportation of the airflow in the inner cavity of the driving head 14 to the outside. An air inlet 111 connected with the inner cavity of the fixed base 12 is opened on the side of the conveying ring belt 11, and a one-way air valve 16 for one-way transportation of the airflow in the air inlet 111 to the inner cavity of the fixed base 12 is fixedly installed on the outer side of the conveying ring belt 11, so that when the movable push plate 13 squeezes the ejection spring 120, the airflow will be blown out from the air jet 140 to the material storage chamber 100, and when the movable push plate 13 is away from the ejection spring 120, the airflow will be supplemented to the inner cavity of the fixed base 12 through the air inlet 111. In order to prevent the airflow sucked in by the air inlet 111 from being blocked by the small particles of raw materials in the material storage chamber 100, combined with Figure 3 An air release groove 102 communicating with the side of the conveyor belt 11 is provided on the surface of the crushing box 1, so that the air inlet 111 is connected with the external air flow.
[0041] When in use, by changing the deflection angle of the crushing cutter 10, the distance that the movable push plate 13 is retracted into the fixed base 12 changes, thereby achieving a change in the feed amount, making the feed amount controllable.
[0042] At the same time, when the fully extended movable push plate 13 is pushed against the crushing cutter 10 by the driving head 14, the movable push plate 13 will be pressed to move toward the fixed base 12, and the air flow in the inner cavity of the fixed base 12 will be blown toward the filter plate 8 through the one-way air valve 16 in the air jet port 140. Since the raw materials crushed by the crushing roller 7 are placed between the filter plate 8 and the driving head 14, when the driving head 14 blows out air flow, the small particles of raw materials will be more likely to move toward the filter plate 8, so that the small particles of raw materials will be screened out.
[0043] Embodiment 4
[0044] This fourth embodiment is a modified improvement of the third embodiment. Figure 4-Figure 6There are at least eight crushing cutters 10, and the crushing cutters 10 are arranged equidistantly, with the cutting edges of the crushing cutters 10 facing the upward fixed base 12. Therefore, in actual use, the crushing cutters 10 will cause the movable push plate 13 to be retracted into the fixed base 12, and the raw materials above the movable push plate 13 can only flow out of the material storage chamber 100 through the crushing cutters 10, and then under the pressure of multiple crushing cutters 10, the raw materials will be chopped, thereby further enhancing the crushing of the raw materials.
[0045] In combination with the above, when the supporting chassis 9 is fixed, although the crushing cutter 10 can crush the raw materials on the movable push plate 13, since the crushing work is carried out by extrusion between the two, the conveying ring belt 11 will increase the resistance as the material extrusion strength continues to increase, so that the material conveying efficiency is reduced, and when the stationary crushing cutter 10 breaks the material, not only is it easy to cause local blockage, but also leads to uneven crushing effect. In order to solve this problem, as a variation of the third embodiment, by canceling the fixation of the supporting chassis 9, a pitch adjustment rod 15 that is pressed against the outside of the active toothed disc 5 is threadedly connected to the top of the crushing cutter 10, so that when the pitch adjustment rod 15 is inserted into the outside of the active toothed disc 5, as the active toothed disc 5 rotates, the crushing cutter 10 will be periodically pushed toward the direction of the driving head 14, which not only achieves the technical problems mentioned above, but also in the process of the reciprocating motion of the movable push plate 13, the airflow in the inner cavity of the fixed base 12 is continuously blown into the storage chamber 100, further aggravating the efficiency of the small particles in the storage chamber 100 to be output outward.
[0046] In order to facilitate the adjustment of the feeding amount of the fixed base 12, the present embodiment has an inspection baffle 4 fixed by bolts on the back of the crushing box 1, and the inspection baffle 4 is located on one side of the distance adjusting rod 15, so that the distance adjusting rod 15 can be observed by removing the inspection baffle 4, and the squeezing strength of the crushing cutter 10 on the movable push plate 13 can be changed by changing the screwing amount of the distance adjusting rod 15, so that the feeding of the fixed base 12 can be controlled.
