Description

Technical Field

[0001] This utility model relates to a solvent-free resin production system, specifically a solvent-free resin production system with quantitative feeding function, and belongs to the field of solvent-free resin production technology. Background Technology

[0002] Solvent-free resins are resin materials that do not require the addition of organic solvents during synthesis, processing, and application. They have significant advantages such as environmental protection, high efficiency, and high performance, and show broad application prospects in fields such as coatings, adhesives, electronics, and composite materials. The raw materials for solvent-free resins are usually solid particles, including epoxy resins, unsaturated polyester resins, polyurethane prepolymers, or silicone resins.

[0003] Currently, solvent-free resins are typically produced by pouring raw materials into a mixing device via a feeding device. The existing feeding method involves installing multiple hoppers containing different raw materials on the production equipment and controlling the feeding of the hoppers through a control device. However, it is difficult to feed multiple raw materials simultaneously through the same drive component, and the valves are opened directly when feeding raw materials, making it difficult to quantitatively feed the materials, resulting in uneven batching and affecting the purity of the solvent-free resin production. Utility Model Content

[0004] The purpose of this invention is to provide a solvent-free resin production system with quantitative feeding function to solve the above problems. It is equipped with a mechanism for simultaneously quantitatively feeding multiple raw materials, and can also feed multiple raw materials individually, making it easy to mix and improve the purity of solvent-free resin.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a solvent-free resin production system with quantitative feeding function, including a fixed plate, on both sides of which a storage mechanism and a driving mechanism are fixed. The driving mechanism includes a second pulley, and the bottom of the fixed plate is provided with the second pulley. A feeding mechanism is installed on the storage mechanism, and the feeding mechanism includes two outer shells. The bottom of the two storage mechanisms is welded with the outer shells, and each of the two outer shells has a feeding port. A material cylinder is horizontally rotatably connected inside each of the two outer shells. Each of the two material cylinders has a hopper corresponding to the feeding port. A transmission mechanism is fixedly connected to each of the two material cylinders. The transmission mechanism includes a rotating shaft, a rod, and a connecting sleeve. Two rotating shafts are fixedly connected to each of the two material cylinders. The rod slides inside the two rotating shafts. Connecting sleeves are fixed on both sides of the second pulley, and the rod is inserted into the inside of the connecting sleeve.

[0006] Preferably, the feeding mechanism further includes limiting rings, and both ends of the two material cylinders are fixedly connected to the limiting rings.

[0007] Preferably, the transmission mechanism further includes a sliding groove, and a sliding groove is provided on both of the two rotating shafts. A slider is slidably connected to each of the two sliding grooves. The slider is fixedly connected to the insertion rod, and the insertion rod has a hexagonal prism structure.

[0008] Preferably, the transmission mechanism further includes a fixed block and a lead screw. Fixed blocks are fixedly connected to both rotating shafts, and lead screws are threadedly connected to both fixed blocks. The two lead screws are rotatably connected to the two sliders respectively.

[0009] Preferably, the driving mechanism further includes side plates and rotating sleeves. Two side plates are welded to the bottom of the fixed plate, and rotating sleeves are rotatably connected to both side plates. The two rotating sleeves are fixed to both sides of the pulley, and the connecting sleeve is located inside the rotating sleeve.

[0010] Preferably, the drive mechanism further includes a motor, the motor is mounted on the fixed plate, the output end of the motor is key-connected to a pulley, and a belt connects the pulley and the second pulley.

[0011] Preferably, the storage mechanism includes two hoppers, each hopper is welded to the top of the two outer shells, and an L-shaped support is welded to the outside of each hopper, with a stirring tank installed at the bottom of the support.

[0012] Preferably, the bottom of the two outer shells is welded with a connecting shell that is hollow inside and open at the bottom, and the connecting shell is connected to the two discharge ports.

[0013] Preferably, the connecting shell has an isosceles trapezoidal structure, and the connecting shell and the fixing plate are arranged in parallel.

[0014] The beneficial effects of this utility model are as follows: If two raw materials need to be added at the same time, the slider can be moved to drive the insert rod to move into the connecting sleeve on the side wall of the pulley. After the insert rod is inserted into the connecting sleeve, the connection between the two rotating shafts and the two connecting sleeves is completed. As long as the pulley rotates, the two rotating shafts will rotate at the same time, and the two material cylinders will rotate at the same time. When the hopper rotates in the opposite direction to the discharge port, the material inside the hopper will fall into the mixing tank for processing. As long as both insert rods are inserted into the connecting sleeve, the pulley can drive the two rotating shafts to rotate at the same time, and the two material cylinders can discharge at the same time. If only one material is needed, the slider can be moved in the opposite direction to pull the insert rod out from the corresponding connecting sleeve. At this time, the corresponding rotating shaft loses its power source and will no longer discharge material. Moreover, quantitative material discharge can be achieved each time, which improves the purity of solvent-free resin processing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8As shown, a solvent-free resin production system with quantitative feeding function includes a fixed plate 1. Storage mechanisms 2 and driving mechanisms 3 are fixed on both sides of the fixed plate 1. The driving mechanism 3 includes a second pulley 305. The bottom of the fixed plate 1 is provided with the second pulley 305. A feeding mechanism 4 is installed on the storage mechanism 2. The feeding mechanism 4 includes two outer shells 401. The bottom of the two storage mechanisms 2 is welded with outer shells 401. Each of the two outer shells 401 has a feeding port 404. The interiors of the two outer shells 401 are horizontally rotating. Each of the two material cylinders 402 has a hopper 405 corresponding to the discharge port 404. A transmission mechanism 5 is fixedly connected to each of the two material cylinders 402. The transmission mechanism 5 includes a rotating shaft 501, a rod 502 and a connecting sleeve 503. Two rotating shafts 501 are fixedly connected to each of the two material cylinders 402. The rod 502 slides inside the two rotating shafts 501. A connecting sleeve 503 is fixed on both sides of the pulley 305. The rod 502 is inserted into the inside of the connecting sleeve 503.

[0026] As a technical optimization of this utility model, the feeding mechanism 4 further includes a limiting ring 403. Both ends of the two material cylinders 402 are fixedly connected to the limiting ring 403 to limit the material cylinders 402 and prevent them from shaking.

[0027] As a technical optimization of this utility model, the transmission mechanism 5 further includes a slide groove 504. Each of the two rotating shafts 501 has a slide groove 504, and a slider 505 is slidably connected to each of the two slide grooves 504. The slider 505 is fixedly connected to the insertion rod 502, and the insertion rod 502 has a hexagonal prism structure. The transmission mechanism 5 also includes a fixing block 506 and a lead screw 507. Each of the two rotating shafts 501 is fixedly connected to a fixing block 506, and a lead screw 507 is threadedly connected to each of the two fixing blocks 506. Each lead screw 507 is rotatably connected to two sliders 505. When the two rotating shafts 501 are connected, rotating both lead screws 507 simultaneously will move the sliders 505. Then, the insert rod 502 is inserted into the connecting sleeve 503, so that both rotating shafts 501 can drive the material cylinder 402 to rotate. Similarly, reversing one of the lead screws 507 will cause the slider 505 to drive the insert rod 502 to retract. Furthermore, the insert rod 502 separates from the connecting sleeve 503, so the corresponding material cylinder 402 will not rotate to feed material.

[0028] As a technical optimization of this utility model, the driving mechanism 3 further includes a side plate 304 and a rotating sleeve 306. Two side plates 304 are welded to the bottom of the fixed plate 1, and rotating sleeves 306 are rotatably connected to both side plates 304. The two rotating sleeves 306 are fixed to both sides of the pulley 305. The connecting sleeve 503 is located inside the rotating sleeve 306. The driving mechanism 3 further includes a motor 301. The motor 301 is installed on the fixed plate 1. The output end of the motor 301 is key-connected to a pulley 302. A belt 303 is connected between the pulley 302 and the pulley 305. When the motor 301 is started, the pulley 302 drives the pulley 305 to rotate, and then the two connecting sleeves 503 will rotate. As long as the insert rod 502 is inserted into the inside of the connecting sleeve 503, the corresponding material cylinder 402 will rotate to feed material.

[0029] As a technical optimization of this utility model, the storage mechanism 2 includes two hoppers 202. The top of each of the two outer shells 401 is welded with a hopper 202. The outer side of each of the two hoppers 202 is welded with an L-shaped support 201. A stirring tank 7 is installed at the bottom of the support 201 to realize the storage and feeding of two raw materials.

[0030] As a technical optimization of this utility model, the bottom of the two outer shells 401 are welded with a connecting shell 6 that is hollow inside and open at the bottom. The connecting shell 6 is connected to the two discharge ports 404. The connecting shell 6 has an isosceles trapezoidal structure and is arranged parallel to the fixing plate 1. After the two raw materials are discharged, they will fall into the interior of the connecting shell 6 together and can mix when they fall.

[0031] In use, the entire structure is installed on top of the solvent-free resin production equipment using screws and bracket 201. The connecting shell 6 is positioned above the production equipment, ensuring that the hoppers 405 on the two material cylinders 402 are misaligned with the discharge port 404, thus ensuring a seal on the discharge port 404. Different raw material particles are added into the two hoppers 202. If two raw materials need to be added simultaneously, the two lead screws 507 can be rotated relative to each other, causing the two lead screws 507 to drive the two sliders 505 to move relative to each other within the slide groove 504. Furthermore, the sliders 505 drive the insert rod 502 to move into the connecting sleeve 503 on the side wall of the pulley 2 305. When the insert rod 502 is inserted into the connecting sleeve 503, the connection between the two rotating shafts 501 and the two connecting sleeves 503 is completed. Whenever the pulley 2 305 rotates, the two rotating shafts 501 will rotate simultaneously, and the two material cylinders 402 will rotate simultaneously. When the hopper 405 rotates and... When the discharge port 404 is facing away from the material, the material inside the hopper 405 will fall into the connecting shell 6, and after mixing, it will fall into the mixing tank 7 for processing. When the hopper 405 is facing the discharge port 404, the raw material inside the hopper 202 will fall into the hopper 405 to complete the feeding. The rotation of pulley 2 305 can start the motor 301 to drive pulley 1 302 to rotate. When pulley 1 302 rotates, the belt 303 can transmit power to pulley 2 305, so that pulley 2 305 can drive the two rotating shafts 501 to rotate at the same time, and the two hoppers 402 can feed at the same time. If only one type of material is needed, the corresponding screw 507 can be rotated in the opposite direction to make the slider 505 slide in the opposite direction, so that the insert 502 can be pulled out from the corresponding connecting sleeve 503. At this time, the corresponding rotating shaft 501 loses its power source and will no longer feed. Moreover, the hopper 405 can achieve quantitative feeding each time, improving the purity of solvent-free resin processing.
