Description

Technical Field

[0001] This utility model relates to the field of epoxy resin recycling technology, specifically to an epoxy resin recycling device. Background Technology

[0002] Epoxy resin is a general term for polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical reactivity of epoxy groups, it can be ring-opened by various compounds containing active hydrogen, curing and cross-linking to form a network structure, thus making it a thermosetting resin. Bisphenol A type epoxy resin not only has the largest production volume and the most complete variety, but new modified varieties are also constantly being added, and the quality is continuously improving. The excellent physical, mechanical, and electrical insulation properties of epoxy resin, its adhesion to various materials, and the flexibility of its application processes are unmatched by other thermosetting plastics. Therefore, it can be made into coatings, composite materials, castings, adhesives, molding materials, and injection molding materials, and is widely used in various sectors of the national economy.

[0003] In the process of crushing and recycling solid epoxy resin, a crusher is usually used to process the solid epoxy resin. The crushed epoxy resin particles will be discharged from the crusher through the screen holes. During this process, some particles that are not much different from the screen holes will get stuck on the screen, which will affect the feeding rate of the particles and thus reduce the efficiency of epoxy resin recycling. To address this, an epoxy resin recycling device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an epoxy resin recycling device to solve the problem mentioned in the background art that, in the process of crushing and recycling solid epoxy resin, a crusher is usually used to process the solid epoxy resin.

During this process, some particles that are not much different from the screen holes will get stuck on the screen, which will affect the feeding rate of the particles and thus reduce the efficiency of epoxy resin recycling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an epoxy resin recycling device, comprising...

[0006] A support frame is provided, on which a crushing assembly is mounted. The crushing assembly is used to crush epoxy resin blocks, and a feeding hopper is installed below the crushing assembly.

[0007] An anti-blocking component is installed inside the hopper;

[0008] The anti-clogging component includes a fixed shaft, a fixed block, a rope, and several fixed rings. The fixed shaft is rotatably connected to the inner side of the hopper. Several mounting slots are provided on the outer side of the fixed shaft. The fixed block is installed inside the mounting slots. The rope is fixedly connected to the fixed block. Threaded sections are provided on both sides of the several mounting slots on the outer side of the fixed shaft. Several fixed rings are threaded to the outer side of the threaded sections. One end of each fixed ring is located on the outer side of the fixed block.

[0009] Preferably, the above-mentioned crushing assembly includes a frame, two rotating shafts, and two crushing rollers. The frame is fixedly connected to the top end of the support frame, the two rotating shafts are rotatably connected to the inner side of the frame, the two crushing rollers are fixedly sleeved on the outer side of the rotating shafts, and a gear is fixedly sleeved on one end of each rotating shaft extending to the outer side of the frame.

[0010] Preferably, a screen is installed inside the frame and below the two crushing rollers, and the screen is located above the fixed shaft.

[0011] Preferably, one end of the aforementioned rotating shaft is fixedly sleeved with a first pulley on the outside of the gear, and one end of the fixed shaft extends to the outside of the hopper and is fixedly sleeved with a second pulley.

[0028] Example

[0029] In the existing technology, during the crushing and recycling of solid epoxy resin, a crusher is usually used to process the solid epoxy resin. The crushed epoxy resin particles are discharged from the crusher through the screen holes. During this process, some particles that are not much different from the screen holes will get stuck on the screen, which will affect the feeding rate of the particles and thus reduce the efficiency of epoxy resin recycling.

[0030] Please see Figure 1-6 This utility model provides a technical solution: an epoxy resin recycling device, including a support frame 1, a crushing component installed on the support frame 1, the crushing component being used to crush epoxy resin blocks, a feeding hopper 9 installed below the crushing component; and an anti-blocking component installed inside the feeding hopper 9.

[0031] By setting up an anti-clogging component, the epoxy resin particles after crushing can be prevented from clogging the screen holes of the screen 5, thereby improving the efficiency of epoxy resin recycling. The anti-clogging component includes a fixed shaft 11, a fixed block 14, a rope 15, and several fixed rings 16. The fixed shaft 11 is rotatably connected to the inner side of the hopper 9. Several mounting grooves 13 are opened on the outer side of the fixed shaft 11. The fixed block 14 is installed inside the mounting groove 13. The rope 15 is fixedly connected to the fixed block 14. The fixed shaft 11 drives the rope 15 to rotate inside the hopper 9. During the rotation, the rope 15 will hit the screen 5, causing the screen 5 to vibrate and shake off the particles clogging the screen holes.

[0032] The outer side of the fixed shaft 11 is provided with threaded sections on both sides of several mounting grooves 13. Several fixing rings 16 are connected to the outer side of the threaded sections by threads, and one end of each fixing ring 16 is located on the outer side of the fixing block 14. By rotating the two fixing rings 16 in the opposite direction, the two fixing rings 16 will move on the threaded sections on the outer side of the fixed shaft 11, so that the opposite ends of the two fixing rings 16 simultaneously disengage from the outer side of the fixing block 14. This allows the rope 15 to be pulled to drive the fixing block 14 out of the mounting groove 13, and the rope 15 can be replaced. This avoids the rope 15 being too short, which would affect the effect of the beating screen 5 and ensure the efficiency of epoxy resin recycling.

[0033] To facilitate the recycling of epoxy resin solids, the crushing assembly includes a frame 2, two rotating shafts 3, and two crushing rollers 4. The frame 2 is fixedly connected to the top end of the support frame 1. The two rotating shafts 3 are rotatably connected to the inner side of the frame 2. The two crushing rollers 4 are fixedly sleeved on the outer side of the rotating shafts 3. One end of each of the two rotating shafts 3 extends to the outer side of the frame 2 and is fixedly sleeved with a gear 6. The two gears 6 mesh with each other. A screen 5 is installed inside the frame 2 and below the two crushing rollers 4. The screen 5 is located above the fixed shaft 11. The top of the frame 2... The feeding hopper 8 is installed in the part, and the other end of the top of the support frame 1 is equipped with a drive motor 7. The output shaft of the drive motor 7 is fixedly connected to the other end of another rotating shaft 3 through a coupling. The output shaft of the drive motor 7 drives the other rotating shaft 3 to rotate through the coupling. One end of the rotating shaft 3 drives another gear 6 to rotate through a gear 6, so that the other gear 6 drives the rotating shaft 3 to rotate. The two rotating shafts 3 drive the two crushing rollers 4 to rotate respectively, so that the epoxy resin block is added into the interior of the feeding hopper 8 and crushed by the two crushing rollers 4.

[0034] One end of a rotating shaft 3 is fixedly sleeved on the outside of the gear 6 with a first pulley 10. One end of a fixed shaft 11 extends to the outside of the hopper 9 and is fixedly sleeved with a second pulley 12. The first pulley 10 and the second pulley 12 are connected by a belt. The two rotating shafts 3 drive the two crushing rollers 4 to rotate, which can complete the crushing and recycling of epoxy resin blocks. At the same time, during the rotation of one rotating shaft 3, the first pulley 10 drives the second pulley 12 to rotate. The second pulley 12 drives the rope 15 to rotate inside the hopper 9 through the fixed shaft 11. The rope 15 can beat the screen 5.

[0035] Working principle or structural principle: When epoxy resin blocks need to be recycled, the drive motor 7 is started by controlling the switch group. The output shaft of the drive motor 7 drives another rotating shaft 3 to rotate through the coupling. One end of the rotating shaft 3 drives another gear 6 to rotate through a gear 6, so that the other gear 6 drives another rotating shaft 3 to rotate. The two rotating shafts 3 drive the two crushing rollers 4 to rotate, and the epoxy resin blocks are added into the inside of the feeding hopper 8. The two crushing rollers 4 can crush them to facilitate the recycling of epoxy resin blocks. The crushed epoxy resin is discharged into the inside of the discharge hopper 9 through the screen 5, thus completing the recycling of epoxy resin blocks.

[0036] During the epoxy resin block crushing and recycling process, the rotation of one rotating shaft 3 drives the first pulley 10 to rotate. The first pulley 10 drives the second pulley 12 to rotate via a belt. The second pulley 12 drives the rope 15 to rotate inside the hopper 9 via the fixed shaft 11. During the rotation, the rope 15 strikes the screen 5, causing the screen 5 to vibrate. This prevents the crushed epoxy resin particles from clogging the screen holes of the screen 5, thus improving the efficiency of epoxy resin recycling. When the rope 15 wears out, by rotating the fixed ring 16 in the opposite direction, the fixed ring 16 will move on the threaded section outside the fixed shaft 11, causing one end of the fixed ring 16 to disengage from the outside of the fixed block 14. By twisting the other fixed ring 16 according to the above steps, it can be disengaged from the outside of the fixed block 14. This allows the rope 15 to be pulled and the fixed block 14 to be disengaged from the inside of the mounting groove 13, thus allowing the rope 15 to be replaced. This prevents the rope 15 from being too short, which would affect the effect of striking the screen 5 and ensure the efficiency of epoxy resin recycling.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
