Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically a feeding device for processing ultrafine fiber powder. Background Technology

[0002] In the production process of ultrafine fiber powder, the raw material feeding stage is crucial, directly affecting the quality of the final product. Extensive research revealed CN210236102U, which discloses a feeding device for processing wood fiber powder. This device includes a driven roller, support legs, and driven wheels. Support plates are located at both ends of the driven roller. A baffle frame is located at the upper end of the support plates, and a baffle plate is mounted on the baffle frame. A brush plate is located at the lower end of the baffle plate. A fastening knob is located on one side wall of the baffle frame. The support legs are located on both sides of the lower end of the support plates, and casters are located at the lower ends of the support legs. The advantages are: by setting up the baffle frame, baffle plate, brush plate, and fastening knob, the material feeding thickness on the Teflon conveyor belt can be easily adjusted, effectively ensuring that the feeding amount of the device is not excessive and also making the feeding more uniform. This allows for stable operation of the next process in wood fiber powder processing, improving the practicality of the device.

[0003] However, in the existing technology, although the feeding thickness can be adjusted, when the feeding thickness is restricted to be too thin, the feeding material will accumulate on the Teflon conveyor belt and is prone to overflow, resulting in the feeding material being spilled. Therefore, a feeding device for processing ultrafine fiber powder is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for processing ultrafine fiber powder, which has the advantage of avoiding material accumulation when controlling the thickness of the feeding material, and solves the problem of material accumulation when the feeding thickness is too thin.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for processing ultrafine fiber powder, comprising a base frame, a feeding mechanism provided on the upper surface of the base frame, and a guiding mechanism mounted above one end of the feeding mechanism; the feeding mechanism includes a mounting frame, and a drive roller and a driven roller are rotatably mounted at both ends of the mounting frame, and the drive roller and the driven roller are connected by a conveyor belt.

[0006] The material guiding mechanism includes a connecting cover, a limiting groove is opened on the top of the connecting cover, a limiting plate is movably locked in the limiting groove, an adjusting screw is threaded on the limiting plate, the bottom end of the adjusting screw extends into the inside of the connecting cover and is rotatably mounted with a connecting frame, and louvered grids are fixedly installed at equal intervals at the bottom of the connecting frame;

[0007] The width of the louvered grid is matched with the width of the conveyor belt.

[0008] Preferably, the base frame includes a base plate, with a trolley frame fixedly mounted at the rear bottom of the base plate. Universal casters with brakes are fixedly mounted at the four corners of the bottom of the trolley frame, and a discharge chute is provided at the front bottom of the base plate. In this design, the base frame is constructed of a sturdy base plate, with its rear end adjustable via the trolley frame. The four corners of the trolley frame are equipped with universal casters with brakes. These casters not only facilitate the movement of the device but also provide stability during operation when needed. The cleverly designed discharge chute at the front of the base plate allows materials to flow smoothly from the conveyor belt, improving discharge efficiency. The use of universal casters with brakes significantly enhances the device's mobility and positioning stability. The discharge chute design optimizes the material discharge process, reducing the risk of material accumulation and spillage.

[0009] Preferably, a hopper is installed at the bottom of the outer bottom plate of the discharge chute, and a protective mechanism is fixedly installed on the upper surface of the outer bottom plate. This cleverly designed connection between the hopper and the discharge chute ensures that the discharged material can directly enter the hopper, preventing spillage and waste. Simultaneously, the protective mechanism provides additional protection for the entire discharge process, preventing material splashing or spillage. The hopper design ensures effective material collection and convenient subsequent processing. The protective mechanism enhances operational safety and reduces material loss during the discharge process.

[0010] Preferably, the protective mechanism includes a protective cover, the rear end of which is fixedly connected to the front end of the connecting cover. Two baffles are fixedly installed on both sides of the rear end of the protective cover, and each baffle is fixedly connected to the inner side of the mounting brackets on both sides of the conveyor belt. In this design, the protective mechanism consists of a protective cover and two baffles, forming a closed protective space. The fixed connection between the rear end of the protective cover and the front end of the connecting cover ensures the stability of the overall structure. The fixed connection between the two baffles and the inner side of the mounting brackets on both sides of the conveyor belt effectively prevents material from splashing and scattering during the conveying process. The design of the protective mechanism provides comprehensive protection, preventing material from splashing and scattering during conveying and discharging, improving material utilization and the cleanliness of the working environment.

[0011] Preferably, a drive motor is fixedly mounted on the upper surface of the base plate at one end of the drive roller, and the drive motor is driven by the drive roller. In this design, the drive motor is fixedly mounted on the upper surface of the base plate at one end of the drive roller, and the motor and the drive roller adopt an efficient transmission installation method, which ensures the effective transmission of power and the stable operation of the conveyor belt. The drive motor provides a stable and powerful power source for the entire material conveying mechanism, ensuring the continuity and uniformity of material conveying.

[0012] Preferably, a pre-drilled hole is provided in the middle of the upper surface of the limiting plate, and a nut post is embedded in the pre-drilled hole. The nut post is threaded onto an adjusting screw, and a bearing is provided at the bottom end of the adjusting screw, which is embedded in the middle of the upper end face of the connecting frame. In this design, the pre-drilled hole in the middle of the upper surface of the limiting plate and the nut post embedded therein, with the nut post connected to the adjusting screw by threads and the bearing at the bottom end of the adjusting screw embedded in the middle of the upper end face of the connecting frame, allow the adjusting screw to remain stable during rotation, ensuring the accuracy and smoothness of the adjustment process. Through this precise design, the adjusting screw can accurately adjust the height of the louvered grid, thereby controlling the material feeding thickness and ensuring the uniformity and controllability of material conveying. The use of the bearing further improves the stability and durability of the adjusting mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By adjusting the screw and the limiting plate, the operator can precisely adjust the height of the louvered grid, thereby controlling the thickness of the material accumulation on the conveyor belt. Since the adjusting screw can move within the limiting groove, this allows the thickness to be dynamically adjusted according to the flow of the material during the feeding process, avoiding accumulation caused by improper thickness control.

[0015] The louvered grids are fixedly installed at equal intervals at the bottom of the connecting frame, and their width matches the width of the conveyor belt. This ensures uniform material distribution and reduces the possibility of local accumulation. At the same time, since the material can continue to be conveyed through the gaps in the louvered grids, it can be discharged through the gaps when material accumulation occurs, thus avoiding the possibility of large accumulation of material on the conveyor belt. In addition, the design of the material guiding mechanism, especially the connecting cover and the limiting groove, provides an operational space for precise control of material thickness. This allows for timely adjustments when material accumulation occurs, preventing unnecessary accumulation of material on the conveyor belt and achieving the effect of avoiding material accumulation when controlling the thickness of the feed.

[0022] 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.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, one embodiment of this utility model is provided: a feeding device for processing ultrafine fiber powder, comprising a base frame 1, a feeding mechanism 2 provided on the upper surface of the base frame 1, and a guiding mechanism 3 mounted above one end of the feeding mechanism 2; the feeding mechanism 2 includes a mounting frame 21, with a drive roller 22 and a driven roller 24 rotatably mounted at both ends of the mounting frame 21, and the drive roller 22 and the driven roller 24 being connected by a conveyor belt 23.

[0025] The material guiding mechanism 3 includes a connecting cover 39. A limiting groove 38 is opened on the top of the connecting cover 39. A limiting plate 36 is movably clamped in the limiting groove 38. An adjusting screw 32 is threaded on the limiting plate 36. The bottom end of the adjusting screw 32 extends into the inside of the connecting cover 39 and is rotatably mounted on a connecting frame 31. Louvered grids 35 are fixedly installed at equal intervals at the bottom of the connecting frame 31.

[0026] The width of the louvered grid 35 matches the width of the conveyor belt 23.

[0027] Specifically, by adjusting the screw 32 and the limiting plate 36, the operator can precisely adjust the height of the louvered grid 35, thereby controlling the accumulation thickness of the material on the conveyor belt 23. Since the adjusting screw 32 can move within the limiting groove 38, this allows the thickness to be dynamically adjusted according to the flow of the material during the feeding process, avoiding accumulation caused by improper thickness control.

[0028] The louvered grids 35 are fixedly installed at equal intervals at the bottom of the connecting frame 31. Their width matches the width of the conveyor belt 23, ensuring uniform material distribution and reducing the possibility of local accumulation. At the same time, since the material can continue to be conveyed through the gaps in the louvered grids 35, it can be discharged through the gaps when material accumulation occurs, thus avoiding the possibility of a large accumulation of material on the conveyor belt 23. In addition, the design of the material guiding mechanism 3, especially the connecting cover 39 and the limiting groove 38, provides an operable space for precise control of material thickness. This allows for timely adjustment when material accumulation occurs, preventing unnecessary accumulation of material on the conveyor belt 23 and achieving the effect of avoiding material accumulation when controlling the thickness of the feed.

[0029] Example 2

[0030] To prevent material spillage during the conveying process, such as Figure 2 and Figure 5 As shown, in this embodiment, the base frame 1 includes a base plate 12. A trolley frame 11 is fixedly installed at the rear bottom of the base plate 12. Universal casters with brakes are fixedly installed at the four corners of the bottom of the trolley frame 11. A discharge chute 13 is provided at the front bottom of the base plate 12. In this design, the base frame 1 is constructed from a sturdy base plate 12, and its rear end is positioned via the trolley frame 11. The four corners of the bottom of the trolley frame 11 are equipped with universal casters with brakes. These casters not only facilitate the movement of the device but also secure the device when needed, ensuring stability during operation. The discharge chute 13 is cleverly designed at the front end of the base plate 12. This design allows materials to be smoothly discharged from the conveyor belt 23, improving discharge efficiency. By equipping the universal casters with brakes, the mobility and positioning stability of the device are significantly improved. The design of the discharge chute 13 optimizes the material discharge process, reducing the risk of material accumulation and overflow.

[0031] Furthermore, a hopper 14 is connected to the bottom of the base plate 12 on the outer side of the discharge chute 13, and a protective mechanism 4 is fixedly installed on the upper surface of the base plate 12 on the outer side of the discharge chute 13. The design cleverly connects the hopper 14 to the bottom of the base plate 12 on the outer side of the discharge chute 13, ensuring that the discharged material can directly enter the hopper 14, avoiding scattering and waste. Simultaneously, the protective mechanism 4 fixedly installed on the upper surface of the base plate 12 on the outer side of the discharge chute 13 provides additional protection for the entire discharge process, preventing material splashing or scattering. The design of the hopper 14 ensures effective material collection and convenient subsequent processing. The presence of the protective mechanism 4 improves operational safety and reduces material loss during the discharge process.

[0032] Furthermore, the protective mechanism 4 includes a protective cover 42, the rear end of which is fixedly connected to the front end of the connecting cover 39. Two baffles 41 are fixedly installed on both sides of the rear end of the protective cover 42, and the two baffles 41 are fixedly connected to the inner sides of the mounting brackets 21 on both sides of the conveyor belt 23. In this design, the protective mechanism 4 consists of the protective cover 42 and two baffles 41, forming a closed protective space. The fixed connection between the rear end of the protective cover 42 and the front end of the connecting cover 39 ensures the stability of the overall structure. The fixed connection between the two baffles 41 and the inner sides of the mounting brackets 21 on both sides of the conveyor belt 23 effectively prevents material from splashing and scattering during the conveying process. The design of the protective mechanism 4 provides comprehensive protection, preventing material from splashing and scattering during conveying and discharging, improving material utilization and the cleanliness of the working environment.

[0033] Example 3

[0034] To ensure the continuity of material conveying and to facilitate the adjustment of the material thickness on the conveyor belt, such as Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a drive motor is fixedly installed on the upper surface of the base plate 12 at one end of the drive roller 22, and the drive motor is driven by the drive roller 22. In this design, the drive motor is fixedly installed on the upper surface of the base plate 12 at one end of the drive roller 22. The motor and the drive roller 22 are connected by an efficient transmission method, ensuring effective power transmission and stable operation of the conveyor belt 23. The drive motor provides a stable and powerful power source for the entire material conveying mechanism 2, ensuring the continuity and uniformity of material conveying.

[0035] Furthermore, a pre-drilled hole 37 is provided in the middle of the upper surface of the limiting plate 36. A nut post 33 is embedded in the pre-drilled hole 37, and an adjusting screw 32 is threaded onto the nut post 33. A bearing 34 is provided at the bottom end of the adjusting screw 32, and the bearing 34 is embedded in the middle of the upper end face of the connecting frame 31. In this design, the pre-drilled hole 37 is cleverly provided in the middle of the upper surface of the limiting plate 36, and the nut post 33 is embedded in it. The nut post 33 is connected to the adjusting screw 32 by threads. The bearing 34 is provided at the bottom end of the adjusting screw 32 and is embedded in the middle of the upper end face of the connecting frame 31. This design allows the adjusting screw 32 to remain stable when rotating, ensuring the accuracy and smoothness of the adjustment process. Through this precise design, the adjusting screw 32 can accurately adjust the height of the louvered grid 35, thereby controlling the material feeding thickness and ensuring the uniformity and controllability of material conveying. The use of the bearing 34 further improves the stability and durability of the adjustment mechanism.

[0036] When using this invention, ensure all components are correctly installed, check that the casters are locked, and ensure the device is stable. Start the drive motor fixed to the upper surface of the base plate 12, which drives the drive roller 22 to rotate via the transmission system. The rotation of the drive roller 22, in turn, drives the driven roller 24 to rotate via the conveyor belt 23, thus conveying the material. Adjust the height of the louvered grid 35 by adjusting the screw 32 and the limiting plate 36 to control the thickness of the material on the conveyor belt 23. Ensure the protective cover 42 and the baffle 41 are correctly installed to prevent material from flying during conveying. If splashed or scattered, the material is conveyed to the discharge chute 13 via the conveyor belt 23 and discharged from the discharge chute 13 to the feed hopper 14. During the entire feeding process, the flow of the material is monitored. If necessary, fine adjustments are made through the nut column 33 and adjusting screw 32 in the reserved hole 37. After the feeding is completed, the drive motor is turned off, the operation of the conveying mechanism 2 is stopped, and all components are checked to ensure that there is no material residue or blockage. The device is prepared for the next use. The device is cleaned and maintained regularly, especially key components such as the louvered grid 35, the conveyor belt 23 and the adjusting screw 32.
