Abstract
Description
Technical Field
[0001] This utility model relates to the field of phenolic resin processing technology, and more specifically, to a phenolic resin production feeding device. Background Technology
[0002] Phenolic resin is an important synthetic polymer material and one of the industrially produced synthetic resins. Due to its excellent properties, phenolic resin is widely used in the industrial field. In the production and processing of phenolic resin, a feeding device is generally used to convey and feed the phenolic resin powder. When the feeding device is working, the drive unit rotates the screw shaft, and the material enters the feed trough from the inlet. Under the push of the screw blades, it moves axially along the feed trough and is finally discharged from the outlet, added to the internal equipment. During the rotation of the screw blades, on the one hand, it generates axial thrust on the material, causing it to be conveyed forward; on the other hand, the rotation of the blades also plays a role in stirring and loosening the material, preventing clumping and ensuring the uniformity of feeding. Since the phenolic resin powder is packaged in bags, the packaging bags need to be opened before feeding, therefore, a bag-breaking operation is necessary.
[0003] In related technologies, during the use of the feeding device, the operator typically moves the bagged phenolic resin to the top of the hopper of the feeding device, and then uses a utility knife or scissors to break the bag, allowing the phenolic resin to enter the hopper so that the feeding device can feed the phenolic resin for use.
[0004] However, in the current use of the feeding device, when bagged phenolic resin powder is placed into the hopper and then the bag is broken by the blade, the hopper cannot support the bagged phenolic resin powder, and it is inconvenient for workers to break the bag from the bottom. This makes it difficult for the feeding device to supply material for breaking the bag, affecting the convenience and efficiency of the feeding device. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-4 This utility model provides a technical solution: a phenolic resin production feeding device, including a base frame 1 and a feeding and bag-breaking mechanism. A hopper 2 is installed on the top of the inner side of the base frame 1, and a motor 3 is installed on the bottom right side of the hopper 2. A feeding shaft 4 connected to the motor 3 is installed at the bottom inside the hopper 2. This device provides a medium for supporting the phenolic resin powder packaging bags that move into the hopper 2, and cuts and breaks the phenolic resin powder packaging bags during the support process, allowing the phenolic resin powder to enter the feed head. The feeding shaft 4 then conveys and feeds the phenolic resin powder that has entered the hopper 2. Therefore, the bag-breaking convenience and operating efficiency of the base frame 1 are improved.
[0031] Reference Figures 1-4 In a preferred embodiment, the feeding and bag-breaking mechanism includes a feeding frame 5, which is fixedly connected to the top of the inner wall of the hopper 2. A bag-breaking seat 6 is installed on the front side of the top of the feeding frame 5. A blade holder 7 is fixedly connected to the bottom of the inner wall of the bag-breaking seat 6. A blade 8 is movably connected inside the blade holder 7. A bag-breaking protection mechanism is movably connected to the top of the bag-breaking seat 6. After the external phenolic resin powder packaging bag is moved into the hopper 2, the feeding frame 5 supports the incoming phenolic resin powder packaging bag. At the same time, the top of the blade 8 contacts the phenolic resin powder packaging bag, breaking the phenolic resin powder packaging bag. The bag-breaking operation allows phenolic resin powder to be discharged into the hopper 2. The bag-breaking protection mechanism includes a protective cover 9, a protective cavity 10, and a protective opening 11. The protective cover 9 is movably connected to the top of the bag-breaking seat 6, the protective cavity 10 is opened at the bottom of the protective cover 9, the bag-breaking seat 6 is located inside the protective cavity 10, and the protective opening 11 is opened at the top of the inner wall of the protective cavity 10. This can form a retractable protective medium between the bag-breaking seat 6 and the top of the cutter seat 7, surrounding the unused blade 8 and preventing accidental injury to workers from the blade 8 being directly exposed. Therefore, the protective performance of the blade 8 is improved.
[0032] Reference Figures 2-3In a preferred embodiment, lifting ports 12 are provided on both sides of the inner wall of the protective cavity 10. Lifting bolts 13, which are threadedly connected to the bag-breaking seat 6, are provided inside the lifting ports 12. This allows for lifting and lowering the protective cover 9 and the bag-breaking seat 6 to prevent separation, thus improving the connection effect between the protective cover 9 and the bag-breaking seat 6. Support grooves 14 are provided on the front and rear sides of the inner walls of the protective cover 9 and the protective seat. A spring 15 is provided inside the bag-breaking seat 6. The outer side of the spring 15 is connected to the inner wall of the support groove 14, which can apply an upward elastic support force to the protective cover 9, so that the protective cover 9 surrounds the outside of the knife holder 7 and the blade 8, thus improving the protective effect of the protective cover 9.
[0033] Reference Figures 2-4 In a preferred embodiment, screw holes 16 are provided on both sides of the rear right side of the blade holder 7. Bolts 17 that contact the blade 8 are threaded inside the screw holes 16, providing a medium for the user to install and fix the blade 8 and the blade holder 7. This improves the convenience of installing and fixing the blade 8 and the blade holder 7. A sliding opening 18 located at the bottom of the bag breaking seat 6 is provided on the front side of the top of the feeding rack 5. A slide seat 19 is movably connected inside the sliding opening 18. The top of the slide seat 19 is fixedly connected to the bottom of the bag breaking seat 6, which can slide and guide the bag breaking seat 6 and the feeding rack 5. This improves the connection and guidance effect between the bag breaking seat 6 and the feeding rack 5.
[0034] Reference Figures 2-3 In a preferred embodiment, a rubber ring 20 is movably connected to the bottom of the slide 19, and a fixed plate 21 is fixedly connected to the bottom of the rubber ring 20. The slide 19 can be used to fix the bag breaking seat 6 and the feeding rack 5 after operation, thus improving the convenience of fixing the bag breaking seat 6 and the feeding rack 5. A screw groove 22 is provided at the bottom of the slide 19, and a stud 23 is threaded inside the screw groove 22. The bottom of the stud 23 is fixedly connected to the top of the fixed plate 21, which can be a medium for applying a clamping force to the fixed plate 21, thus improving the force application and fixing effect of the fixed plate 21.
[0035] Specifically, the working process or working principle of this phenolic resin production feeding device is as follows: During use, according to the actual bag-breaking requirements, the hand-held bag-breaking seat 6 is moved back and forth to adjust the position of the blade 8. At this time, the slide 19 moves with the bag-breaking seat 6 inside the slide opening 18, guiding the bag-breaking seat 6 and the feeding rack 5. Then, the hand-held fixed plate 21 drives the stud 23 to rotate and engage with the screw groove 22, applying an upward threaded force to the fixed plate 21, causing the fixed plate 21 to drive the rubber ring 20 to contact and abut against the bottom of the feeding rack 5, clamping and fixing the bag-breaking seat 6 and the feeding rack 5 after the translation operation. Subsequently, the external phenolic resin powder packaging bag is moved to the top of the feeding rack 5 to support it. At this time, the protective cover 9 moves downward under the influence of the weight of the phenolic resin powder packaging bag, causing the blade 8 to protrude from the protective cover 9 through the protective opening 11 and contact the phenolic resin powder packaging bag, cutting and breaking the bag. Phenolic resin powder is discharged from the packaging bag and enters the hopper 2, so that the motor 3 drives the feeding shaft 4 to convey and feed the phenolic resin powder into the hopper 2. During this process, the spring 15 is contracted by the downward movement of the protective cover 9, preparing for the subsequent upward reset of the protective cover 9. At the same time, the screw hole 16, in conjunction with the bolt 17, secures the blade 8 and the blade holder 7, ensuring the stability of the blade 8 during the bag-breaking process. When the phenolic resin powder inside the packaging bag is completely discharged, the hopper 2 is moved by hand. At this time, the downward pressure on the top of the protective cover 9 disappears, and the contracted spring 15, in conjunction with the support groove 14, applies an upward reset thrust to the protective cover 9. At the same time, the lifting bolt 13, in conjunction with the lifting port 12, connects the protective cover 9 and the bag-breaking seat 6, ensuring the reset stability of the protective cover 9, so that the protective cover 9, together with the bag-breaking seat 6 and the blade 8, can perform bag-breaking work on subsequent phenolic resin powder packaging bags.
[0036] It should be noted that the base frame 1, hopper 2, motor 3 and feeding shaft 4 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
