Description

Technical Field

[0001] This application relates to the field of adhesive technology, specifically a sieving device for adhesive processing raw materials. Background Technology

[0002] Adhesives, simply put, are glues. They are substances that can tightly bond two or more surfaces together through surface adhesion and cohesion. There are many types of adhesive raw materials, and their formulation directly affects the performance of the final product, such as bond strength, toughness, temperature resistance, weather resistance, and curing speed. Sieving adhesive raw materials is a crucial pretreatment step in the production process, mainly used to remove impurities, lumps, and large particles, ensuring uniform particle size, improving mixing uniformity, and enhancing the performance of the final product.

[0003] Currently, fixed raw materials (powders, granules) are mostly screened and filtered by vibrating screens. The motor drives the eccentric block to generate three-dimensional vibration, causing the material to be thrown up on the screen. However, the screen is prone to clogging after long-term use, and it is inconvenient to disassemble and install, making it difficult to use.

[0004] Therefore, this application provides a sieving device for adhesive processing raw materials to solve the above problems. Utility Model Content

[0005] This application provides a sieving device for adhesive processing raw materials, which aims to solve the problems mentioned in the background art. The existing fixed raw materials (powder, granules) are mostly screened and filtered by vibrating screens. The motor drives the eccentric block to generate three-dimensional vibration, which makes the material move up and down on the screen. However, the screen is prone to clogging after long-term use, and it is inconvenient to disassemble and install, making it difficult to use.

[0006] To achieve the above objectives, this application provides the following technical solution: a sieving device for adhesive processing raw materials, wherein the sieving device for adhesive processing raw materials includes a sieving mechanism;

[0007] To address the problems of existing methods that primarily use vibrating screens to screen and filter raw materials, where a motor-driven eccentric block generates three-dimensional vibration to toss the material across the screen, but the screens are prone to clogging after prolonged use, making disassembly and installation inconvenient and difficult to use, a new screening mechanism is proposed. This mechanism includes a base and a screening trough. A vibrating motor is positioned at the center of the base, below the screening trough. A spring is fixedly connected between the base and the outside of the screening trough. A fixing rod is fixedly connected to the top of the base. A sliding rod is fixedly connected to the outside of the screening trough. A fixing plate is fixedly connected inside the screening trough. A mounting plate is positioned on top of the fixing plate. A screen is placed between the fixing plate and the mounting plate. A plug-in block is fixedly connected to the bottom of the mounting plate. The interior of the mounting plate has a plug-in slot that matches the plug-in block. The plug-in block engages with the slot. The screen is placed inside the mounting plate and fixed between the mounting plate and the mounting plate by engaging the plug-in block at the bottom of the mounting plate with the slot inside the mounting plate. Raw materials are placed above the screen. A vibration motor drives the screening trough to shake, stretching a spring at the bottom of the screening trough. The screening trough also causes a sliding rod to slide inside the fixed rod. The up-and-down shaking of the screening trough causes the screen to shake. This screen facilitates the screening of adhesive raw materials and allows for easy installation and disassembly according to usage requirements. Operation is simple, quick, and convenient.

[0008] Preferably, to address the issue of convenient spring use, the sliding rod is located inside the fixed rod and is slidably connected to the fixed rod. The spring is located outside the fixed rod and the sliding rod, and the sliding rod is slidably connected to the fixed rod. This design limits the movement distance of the sliding rod and prevents damage to the spring due to excessive swaying, making it convenient to use.

[0009] Preferably, in order to solve the problem of easy installation and disassembly of the screen, the fixing plate and the mounting plate have internal grooves, and the grooves of the fixing plate and the mounting plate are adapted to the screen. The screen is adapted to the internal grooves of the fixing plate and the mounting plate, thereby facilitating the installation and disassembly of the screen and making it easy to use.

[0010] Preferably, to address the issues of convenient cleaning of impurities during raw material screening and easy discharge of the screened material, the base is internally fixed with multiple sets of fixing blocks. Guide rods are fixedly connected between these fixing blocks, and linear motors are slidably connected to the outside of the guide rods. A slider is mounted on the top of each linear motor, and mounting slots are fixedly connected between the linear motors. A cleaning block is installed inside each mounting slot, and the cleaning block is inserted into the mounting slot and secured with bolts. The slider drives the linear motors to slide outside the guide rods fixed between the fixing blocks, allowing the linear motors to move the mounting slots, which in turn move the cleaning blocks. Two sets of cleaning blocks are provided, each set fitting against the bottom surface of the screening tank and the top of the screen, respectively. This facilitates the cleaning of impurities during raw material screening and the easy discharge of the screened material from the screening tank, saving manpower, and providing a simple, quick, and convenient operation.

[0011] Preferably, to address the issue of ease of operation, the fixing blocks are respectively fixedly connected to the four corners of the inner bottom surface of the screening tank and the four corners of the top of the mounting plate. The fixing blocks are respectively fixed to the four corners of the inner bottom surface of the screening tank and the four corners of the top of the mounting plate, thereby facilitating the discharge of raw materials inside the screening tank and facilitating the cleaning of impurities screened on the top of the screen, making it convenient to use.

[0012] Preferably, in order to solve the problem of convenient use of the screening tank, a sealing groove is fixedly connected to the outside of both sides of the screening tank, and a sealing plate is slidably connected inside the sealing groove. The sealing plate is adapted to both sides of the screening tank and slides inside the sealing groove. The sealing plate can seal the screening tank, thereby facilitating the screening of the screening tank.

[0013] This screening mechanism places the screen inside a fixed plate and connects it to a slot inside the fixed plate via a connecting block at the bottom of the mounting plate. This secures the screen between the fixed plate and the mounting plate. Raw materials are placed on top of the screen, and a vibrating motor drives the screening trough to shake. The screening trough stretches a spring at its bottom, causing a sliding rod to slide inside the fixed rod. The up-and-down movement of the screening trough causes the screen to shake. This screen facilitates the screening of adhesive raw materials and allows for easy installation and removal according to usage requirements. The operation is simple, quick, and convenient.

[0014] This screening mechanism inserts cleaning blocks into the installation slot and fixes them in place with bolts. A linear motor driven by a slider slides outside a guide rod fixed between the blocks, allowing the linear motor to move the installation slot. The installation slot then moves the cleaning blocks. Two sets of cleaning blocks are provided, each set fitting against the bottom surface of the screening slot and the top of the screen, respectively. This facilitates the cleaning of impurities from the raw material and allows for easy discharge of the screened material from the screening slot. It saves manpower, is simple and quick to operate, and is easy to use. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a sieving device for adhesive processing raw materials, such as... Figure 1-5As shown, the adhesive processing raw material screening device includes a screening mechanism 1.

[0025] The screening mechanism 1 allows for easy screening of adhesive raw materials, and the screen 19 can be easily installed and disassembled according to usage requirements. The operation is simple, quick, and convenient.

[0026] Specifically, the screening mechanism 1 includes a base 11 and a screening trough 13. A vibration motor 12 is installed at the center of the base 11 and is located below the screening trough 13. A spring 14 is fixedly connected between the base 11 and the outside of the screening trough 13. A fixing rod 15 is fixedly connected to the top of the base 11. A sliding rod 16 is fixedly connected to the outside of the screening trough 13. A fixing plate 17 is fixedly connected inside the screening trough 13. An mounting plate 18 is installed on the top of the fixing plate 17. A screen 19 is installed between the fixing plate 17 and the mounting plate 18. An insertion block 20 is fixedly connected to the bottom of the mounting plate 18. An insertion groove 21 that matches the insertion block 20 is opened inside the fixing plate 17. The insertion block 20 is inserted into the insertion groove 21.

[0027] In use, the screen 19 is placed inside the fixed plate 17 and connected to the insertion slot 21 inside the fixed plate 17 via the insertion block 20 at the bottom of the mounting plate 18. This fixes the screen 19 between the fixed plate 17 and the mounting plate 18. The raw material is placed above the screen 19, and the vibration motor 12 drives the screening trough 13 to shake. The screening trough 13 stretches the spring 14 at its bottom, and the screening trough 13 drives the sliding rod 16 to slide inside the fixed rod 15. The up-and-down shaking of the screening trough 13 causes the screen 19 to shake. The screen 19 facilitates the screening of adhesive raw materials and allows for easy installation and removal according to usage requirements. The operation is simple, quick, and convenient. The operating frequency of the vibration motor 12 is 20Hz to 50Hz, with a preferred range of 25Hz to 30Hz. The vibration frequency is 5Hz to adapt to the screening requirements of adhesive raw materials with different particle sizes. The amplitude range of the vibration motor 12 is 2mm to 10mm, preferably 3mm to 5mm, to ensure that the raw materials are effectively thrown up on the screen 19 and to avoid particle splashing. The stiffness coefficient of the spring 14 is 50N / mm to 200N / mm, preferably 80N / mm to 120N / mm, to ensure that the screening tank 13 remains stable during vibration and to avoid equipment damage caused by resonance. The spring material is stainless steel or silicon-manganese alloy, which is fatigue-resistant and corrosion-resistant. The aperture range of the screen 19 is 20 mesh to 200 mesh (corresponding to a particle size of about 0.075mm to 0.85mm), preferably 40 mesh to 100 mesh, to meet the screening requirements of most adhesive raw materials. The screen material is 304 stainless steel or nylon, and different mesh sizes of screens can be replaced to adapt to different raw materials.

[0028] Furthermore, the sliding rod 16 is located inside the fixed rod 15 and is slidably connected to the fixed rod 15. The spring 14 is located outside the fixed rod 15 and the sliding rod 16, and is slidably connected to the fixed rod 15. This can limit the movement distance of the sliding rod 16 and prevent the spring 14 from being damaged due to large-scale shaking, making it convenient to use.

[0029] Furthermore, the fixing plate 17 and the mounting plate 18 have internal slots that are compatible with the screen 19. The screen 19 is compatible with the internal slots of the fixing plate 17 and the mounting plate 18, which facilitates the installation and disassembly of the screen 19 and makes it easy to use.

[0030] Example 2

[0031] Unlike Embodiment 1, in order to solve the problem of convenient cleaning of impurities after screening and convenient discharge of the screened raw materials, multiple sets of fixing blocks 22 are fixedly connected inside the base 11. Guide rods 23 are fixedly connected between the multiple sets of fixing blocks 22. Linear motors 24 are slidably connected to the outside of the guide rods 23. A slider 25 is provided on the top of the linear motors 24. Mounting grooves 26 are fixedly connected between the linear motors 24. A cleaning block 27 is provided inside the mounting groove 26. The cleaning block 27 is inserted into the mounting groove 26, and the mounting groove 26 and the cleaning block 27 are fixed by bolts.

[0032] In use, the cleaning block 27 is inserted into the mounting slot 26 and fixed inside the mounting slot 26 with bolts. The linear motor 24, driven by the slider 25, slides outside the guide rod 23 fixed between the fixed blocks 22, which allows the linear motor 24 to move the mounting slot 26. The mounting slot 26 then moves the cleaning block 27. There are two sets of cleaning blocks 27, and the two sets of cleaning blocks 27 are respectively attached to the bottom surface of the screening tank 13 and the top of the screen 19. This makes it easy to clean impurities from the raw material screening and to discharge the screened raw material from the screening tank 13. It saves manpower, is simple and quick to operate, and is easy to use. The linear motor 24 drives the cleaning block to move at a speed of 0.1m / s to 0.5m / s, ensuring cleaning efficiency without damaging the screen 19.

[0033] Specifically, the fixing blocks 22 are fixedly connected to the four corners of the inner bottom surface of the screening tank 13 and the four corners of the top of the mounting plate 18, respectively. The fixing blocks 22 are fixed to the four corners of the inner bottom surface of the screening tank 13 and the four corners of the top of the mounting plate 18, which facilitates the discharge of raw materials inside the screening tank 13 and the cleaning of impurities screened on the top of the screen 19, making it convenient to use.

[0034] Furthermore, sealing grooves 28 are fixedly connected to the outside of both sides of the screening trough 13, and sealing plates 29 are slidably connected inside the sealing grooves 28. The sealing plates 29 are adapted to both sides of the screening trough 13 and slide inside the sealing grooves 28. The sealing plates 29 can seal the screening trough 13, thereby facilitating the screening of the screening trough 13. The material of the sealing plates 29 is rubber or polyurethane, and the sealing gap is ≤1mm to prevent the leakage of fine particles.

[0035] It should be noted that the vibration motor 12 and the slider 25 are existing devices, and their working principle, size and model are not related to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0036] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
