Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a feeding hopper for epoxy resin adhesive processing. Background Technology

[0002] In the processing of epoxy resin adhesives, especially during the feeding stage of mixing and stirring, the stability of the raw materials directly affects product quality and production efficiency. Epoxy resin adhesive raw materials (such as epoxy resin, curing agent, filler, etc.) are prone to clumping during storage and transportation due to changes in environmental humidity, compression, and collisions.

[0003] Existing feeding devices often have traditional feeding hoppers with a single funnel structure, lacking effective material filtration and grading mechanisms. Agglomerated materials directly enter the processing equipment, easily causing inlet blockage, uneven mixing, product performance fluctuations, and even damage to the mixing paddle and grinding components of the processing equipment. At the same time, existing feeding devices with filtration functions often have fixed filter screens, which are easily clogged by agglomerated materials during filtration. This requires frequent shutdowns for disassembly and cleaning, seriously affecting production continuity and causing material waste and environmental pollution during the cleaning process. To address the problems existing in the prior art, this utility model proposes a feeding hopper for epoxy resin adhesive processing. By optimizing the conveying structure, the rotatable filtration mechanism, and the material selection, it achieves efficient material conveying, precise filtration of agglomerates, and anti-clogging of the filter screen, thereby improving feeding stability and ease of operation, and ensuring the processing quality of epoxy resin adhesive. Utility Model Content

[0004] In view of this, the present invention provides a feeding hopper for epoxy resin processing, which realizes efficient material conveying, precise filtration of agglomerates, and anti-clogging of the filter screen, improves feeding stability and ease of operation, and greatly improves material feeding efficiency and processing quality.

[0005] To solve the above-mentioned technical problems, this utility model provides a feeding hopper for epoxy resin processing, including a feeding bin mounted on a frame, located above the feed inlet of the processing equipment. A conveying cylinder is connected to the bottom of the feeding bin, and a driving component is located at one end of the conveying cylinder. A rotating shaft is located at the output shaft end of the driving component, penetrating the side wall of the conveying cylinder. Spiral conveying blades are mounted on the outer wall of the rotating shaft inside the conveying cylinder. A discharge port is also located on the side wall of the conveying cylinder, and a filter screen is installed inside the conveying cylinder at the discharge port. This utility model can efficiently and quickly guide and discharge the material at the bottom of the feeding bin by driving the rotating shaft and spiral conveying blades together with the driving component. Furthermore, the filter screen can effectively block and isolate the conveyed material, especially agglomerated material, greatly improving the particle size uniformity of the feed material. This eliminates the need for subsequent sorting operations and improves the stability of the processing equipment.

[0006] The filter screen has a ring structure and is rotatably mounted inside the feed cylinder. This design allows for easy filtration by rotating the screen at a certain angle when it becomes clogged, while also allowing material stuck in the mesh to slide freely off due to its own gravity during rotation.

[0007] A rotating groove is provided at the end of the conveying cylinder along the material conveying direction, and a rotating ring adapted to the rotating groove is provided at the end of the filter screen. This utility model can achieve easy and stable guiding of the filter screen through the cooperation of the rotating ring and the rotating groove, greatly improving the rotational stability of the filter screen.

[0008] The filter screen has a grip on its outer side wall. The grip facilitates the operator's handling.

[0009] A discharge cylinder connected to the discharge port is installed. The discharge cylinder facilitates the guiding operation of material discharge.

[0010] The grip is located inside the discharge cylinder, with its lowest point lower than the lowest point of the discharge cylinder. This makes it easy for the operator to grip or use tools to push the grip to rotate the filter screen.

[0011] The driving component is a servo motor.

[0012] The feed hopper has a structure where the opening at the top is larger than the opening at the bottom. This allows for a certain slope, facilitating the smooth sliding of materials during operation.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Precise filtration and improved feed uniformity: The annular filter screen is made of 316 stainless steel woven mesh with precise mesh size, which can effectively intercept lumpy materials in epoxy resin raw materials, ensuring that the particle size of the material entering the processing equipment is uniform. This solves the technical problem of poor filtration effect of existing devices leading to clogging of processing equipment and fluctuations in product quality, and improves the processing stability and product qualification rate of epoxy resin.

[0014] 2. Rotatable and anti-clogging, ensuring continuous production: The filter screen can rotate flexibly through the cooperation of the rotating ring and the rotating groove. When clogged, it can be quickly cleared by the gripping part without stopping the machine for disassembly. This solves the technical problems of existing fixed filter screens being prone to clogging and requiring frequent machine shutdowns for cleaning, reducing downtime and greatly improving production efficiency.

[0015] 3. High-efficiency conveying and avoidance of material accumulation: The spiral conveyor blades are driven by a servo motor, which provides strong pushing power. Combined with the funnel-shaped structure and polished inner wall of the feed hopper, it effectively solves the problems of accumulation and poor conveying caused by the viscosity of epoxy resin raw materials. The material conveying speed is precise and controllable, and it can adapt to the feeding needs of different processing equipment.

[0016] 4. Easy to operate and low maintenance cost: The grip is designed inside the discharge cylinder and below the lowest end of the discharge cylinder, providing ample operating space. The filter screen can be rotated and unblocked without disassembling any parts. Each component adopts a modular design, making installation and disassembly convenient. The filter screen can be removed separately for cleaning or replacement, reducing maintenance workload and cost. This solves the technical problems of cumbersome operation and inconvenient maintenance of existing devices. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-4As shown: This embodiment provides a feeding hopper for epoxy resin processing, including a feeding bin 200 mounted on a frame 100. The feeding bin 200 is located above the feed inlet of the processing equipment. The feeding bin 200 is made of 316 stainless steel through stamping and welding. 316 stainless steel has excellent corrosion resistance, wear resistance, and structural strength, and can resist the erosion of epoxy resin raw materials and chemicals in the processing environment. Stamping ensures the regularity of the feeding bin 200's structure, and the welded joints are ground and treated with anti-corrosion measures to ensure sealing performance and service life. The feeding bin 200 has a funnel-shaped structure with an upper opening larger than a lower opening. The inner wall is polished to reduce the friction between the material and the bin wall, facilitating the smooth sliding of the material under gravity and preventing accumulation. The feed hopper 200 is located above the feed inlet of the processing equipment. A conveyor cylinder 300 is connected to the bottom of the feed hopper 200. A drive unit 400 is located at the end of the conveyor cylinder 300, and a rotating shaft 500 is located at the output shaft end of the drive unit 400. The rotating shaft 500 is made of 45# steel, machined and quenched. After quenching, the hardness of the rotating shaft 500 reaches HRC45-50, possessing good wear resistance and torsional strength. The rotating shaft 500 penetrates the side wall of the conveyor cylinder 300, and a sealed bearing is installed at the connection point with the conveyor cylinder 300. The sealed bearing is an SKF 6205-2RS1 deep groove ball bearing, characterized by good sealing performance and low rotational resistance, ensuring smooth rotation of the rotating shaft 500 and preventing material leakage from gaps. A spiral conveying blade 600 is fixedly installed on the outer wall of the rotating shaft 500 inside the conveying cylinder 300. The spiral conveying blade 600 is made of wear-resistant alloy steel through forging and milling. Wear-resistant alloy steel has the characteristics of high hardness and high wear resistance, which can resist the frictional wear of epoxy resin raw materials. The spiral conveying blade 600 is fixedly connected to the rotating shaft 500 by welding. The weld is inspected for flaws to ensure the connection strength. The spiral helix angle of the blade is optimized to improve the material pushing efficiency. The rotating shaft 500 passes through the side wall of the conveying cylinder 300. The spiral conveying blade 600 is installed on the outer wall of the rotating shaft 500 inside the conveying cylinder 300. A discharge port 310 is also provided on the side wall of the conveying cylinder 300. A filter screen 700 is installed inside the conveying cylinder 300 at the discharge port 310. The conveying cylinder 300 and the feeding bin 200 are sealed together by welding. The conveying cylinder 300 is also made of 316 stainless steel and is processed by bending and welding. The cylinder wall thickness is uniform, which ensures the structural stability during the conveying process and avoids deformation due to material pressure.A drive unit 400 is fixedly installed at the end of the conveying cylinder 300. The drive unit 400 is a servo motor, specifically a model MSMF042L1U2M servo motor manufactured by Panasonic Corporation. This servo motor features precise speed control, smooth operation, and low noise. The servo motor is detachably connected to the end of the conveying cylinder 300 via a flange made of 304 stainless steel. A nitrile rubber sealing gasket is installed on the connection surface to prevent material leakage and dust ingress. This invention enables the drive unit 400 to drive the rotating shaft 500 and the screw conveyor blades 600 to rotate simultaneously, achieving efficient and rapid guidance and discharge of materials from the lower part of the feed hopper 200. Furthermore, the filter screen 700 effectively blocks and isolates conveyed materials, especially agglomerated materials, greatly improving the particle size uniformity of the feed material. This eliminates the need for subsequent sorting operations and enhances the stability of the processing equipment.

[0021] According to one embodiment of the present invention, such as Figure 1-2 As shown, the filter screen 700 has a ring structure and is rotatably mounted inside the feed cylinder 300. This facilitates the filtration process by rotating the filter screen at a certain angle when it becomes clogged, while also allowing the material clogged in the mesh of the filter screen 700 to slide freely off due to its own gravity during rotation.

[0022] like Figure 4 As shown, a rotating groove 320 is provided at the end of the conveying cylinder 300 along the material conveying direction, and a rotating ring 710 adapted to the rotating groove 320 is provided at the end of the filter screen 700. The rotating groove 320 is an annular groove, made by milling, and the groove width is adapted to the rotating ring 710 at the end of the filter screen 700. The rotating ring 710 adapted to the rotating groove 320 is fixedly provided at the end of the filter screen 700. The rotating ring 710 is made of 316 stainless steel and machined. The rotating ring 710 and the filter screen 700 are fixedly connected by welding. The rotating ring 710 is embedded in the rotating groove 320 and slides in the rotating groove 320 with a clearance ≤0.2mm, ensuring that the filter screen 700 rotates smoothly and does not produce radial offset, thus achieving stable guidance. This utility model can achieve easy and stable guiding of the filter screen 700 through the cooperation of the rotating ring 710 and the rotating groove 320, greatly improving the rotational stability performance of the filter screen 700.

[0023] like Figure 1 and Figure 4As shown, a gripping part 720 is provided on the outer wall of the filter screen 700. The gripping part 720 is made of ABS engineering plastic through injection molding. ABS engineering plastic has the characteristics of wear resistance, impact resistance, and comfortable feel. The surface is provided with anti-slip textured surfaces for easy gripping by the operator. The gripping part 720 is located inside the discharge cylinder 330, and the lowest point of the gripping part 720 is lower than the lowest point of the discharge cylinder 330. The gripping part 720 can be pushed manually or with the aid of tools without disassembling the discharge cylinder 330, causing the filter screen 700 to rotate around the axis of the rotating shaft 500, making operation convenient. The gripping part 720 facilitates the operator's gripping operations.

[0024] A discharge cylinder 330 is connected to the discharge port 310. The discharge cylinder 330 is made of 316 stainless steel and welded together. The axis of the discharge cylinder 330 forms a 30°-60° angle with the conveyor cylinder 300, facilitating the smooth discharge of materials and their introduction into the feed inlet of the processing equipment. A filter screen 700 is installed inside the conveyor cylinder 300 located at the discharge port 310. The filter screen 700 has a ring structure and is made of 316 stainless steel woven mesh through cutting, edging, and welding. The mesh size of the filter screen 700 is set according to the processing requirements of the epoxy resin adhesive (usually 0.5-5mm), which can accurately intercept agglomerated materials and ensure uniform particle size of the passing materials. The uniform weaving density of the filter screen 700 prevents deformation or damage due to material impact during filtration. The discharge cylinder 330 facilitates the guiding operation of material discharge.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the gripping part 720 is located inside the discharge cylinder 330, and its lowest point is lower than the lowest point of the discharge cylinder 330. This makes it easy for the operator to grip or use tools to push the gripping part 720 to rotate the filter screen 700.

[0026] The drive unit 400 is a servo motor.

[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the feed hopper 200 has a structure where the upper opening is larger than the lower opening. This facilitates the creation of a certain slope, allowing materials to slide down smoothly.

[0028] Working principle and usage of this utility model: First, it needs to be clarified that the feeding hopper involved in this utility model is mainly used for guiding materials during the processing. Taking the feeding process of the feeding hopper for epoxy resin mixing and processing as an example, this utility model will explain its working principle and usage method in detail. The working principle is as follows: This device achieves efficient and precise feeding of epoxy resin raw materials through the synergistic effect of "gravity feeding + spiral pushing + annular filter + rotatable anti-clogging". The specific working principle is as follows: Material feeding and sliding: The epoxy resin raw material is poured into the upper opening of the feeding hopper 200. The funnel-shaped structure and polished inner wall of the feeding hopper 200 guide the material to slide down to the bottom conveying cylinder 300, avoiding material accumulation in the hopper and ensuring smooth material discharge. Screw conveyor: Start the servo motor (drive unit 400), the output shaft of the servo motor drives the rotating shaft 500 to rotate synchronously, and the screw conveyor blades 600 on the rotating shaft 500 rotate accordingly. The screw blades generate axial thrust through rotation, which smoothly pushes the material in the conveying cylinder 300 towards the discharge port 310. The pushing speed can be precisely adjusted by the speed of the servo motor to adapt to the feeding requirements of different processing equipment. Agglomeration filtration: During the feeding process, the material passes through the annular filter screen 700. Material with the required particle size passes through the mesh of the filter screen 700 and enters the discharge cylinder 330, and is finally introduced into the feed inlet of the processing equipment. Agglomerate material is intercepted by the filter screen 700 and cannot pass through the mesh, thus achieving graded filtration of the material and ensuring that the particle size of the material entering the processing equipment is uniform. Filter screen anti-clogging and cleaning: When the mesh of the filter screen 700 is clogged by clumps of material, the operator can manually or with the help of tools push the filter screen 700 to rotate around the mating structure of the rotating ring 710 and the rotating groove 320 through the grip part 720 in the discharge cylinder 330. During the rotation, the clumps of material clogged in the mesh will fall off under the action of gravity and centrifugal force and fall to the bottom of the conveying cylinder 300 or be pushed to the collection area outside the discharge port 310 with the subsequent material. The filter screen can be unblocked without stopping the machine to remove it, ensuring that the filtration and conveying operation can continue. The usage method is as follows: Installation and commissioning: Fix the feed hopper 200 to the frame 100 with bolts, ensuring that the feed hopper 200 is directly above the feed inlet of the processing equipment and that the outlet of the discharge cylinder 330 is aligned with the feed inlet of the processing equipment; weld and fix the conveying cylinder 300 to the feed hopper 200, install the servo motor, rotating shaft 500 and spiral conveying blades 600, ensuring that the rotating shaft 500 rotates smoothly and that the spiral blades do not interfere with the inner wall of the conveying cylinder 300; embed the rotating ring 710 of the annular filter screen 700 into the rotating groove 320 of the conveying cylinder 300, check the rotation flexibility of the filter screen 700, and ensure that the grip 720 is easy to operate; connect the servo motor and the control system, conduct a no-load test run, test the motor speed, the pushing effect of the spiral blades, and the smoothness of the rotation of the filter screen 700, and debug until all components are operating normally. Parameter settings: Based on the feeding speed requirements of the processing equipment, the operating speed of the servo motor is set through the control system to ensure that the material conveying speed matches the processing capacity of the equipment; based on the particle size requirements of the epoxy resin raw material, a 700 filter screen with the corresponding mesh size is selected and installed in place. Feeding operation: Pour the epoxy resin raw material evenly into the feeding hopper 200. The raw material slides down the inner wall of the feeding hopper 200 to the conveying cylinder 300. Start the servo motor, and the spiral conveyor blades 600 rotate to push the material. After being filtered by the filter screen 700, the qualified material enters the processing equipment through the discharge cylinder 330. During operation, observe the material conveying status and filtration effect. If the material conveying is not smooth or the discharge volume is reduced, it indicates that the filter screen is blocked. The filter screen 700 is cleared by rotating the grip part 720. Cleaning and Maintenance: After processing, turn off the servo motor and stop feeding; open the inspection cover at the end of the conveyor cylinder 300 and clean the residual material inside the conveyor cylinder 300; remove the filter screen 700, rinse the residual clumps in the mesh with a high-pressure water gun, dry it, and reinstall it; check the wear of the screw conveyor blades 600, the rotating shaft 500, and the sealed bearings, and replace them in time if the wear is serious; perform regular maintenance on the servo motor, add lithium-based grease, check the electrical circuit connection status, and ensure long-term stable operation of the device.

[0029] This invention, through the design of a feeding hopper for epoxy resin adhesive processing, achieves efficient material conveying, precise filtration of agglomerates, and anti-clogging of the filter screen, thereby improving feeding stability and ease of operation, and greatly enhancing material feeding efficiency and processing quality.
