Description

Technical Field

[0001] This utility model relates to the field of rubber adhesive production, and more specifically, to a purification device for rubber adhesive production. Background Technology

[0002] Rubber adhesives are a class of adhesives used to firmly bond rubber to rubber or rubber to other materials. They are usually rubber-based substances with good adhesive properties, such as chloroprene rubber, nitrile rubber, and natural rubber. These rubber molecules have high flexibility and viscosity, and can form a strong adhesion to the surface of the adhered objects. Some rubber adhesives require the addition of curing agents to promote cross-linking reactions, thereby improving the bonding strength and properties such as heat resistance and water resistance. For example, zinc oxide and magnesium oxide are used as curing agents in some chloroprene rubber adhesives. To improve the flexibility and processing performance of rubber adhesives, plasticizers are often added. These plasticizers can reduce the intermolecular forces of rubber, allowing the adhesive to maintain good flexibility at low temperatures and not easily crack. Common plasticizers include phthalates and phosphate esters.

[0003] A search revealed an existing patent (publication number: CN221620017U) that discloses a purification device for adhesive production. The device includes a body and a dust cover on top of the body. A vibration mechanism is located at the bottom of the body, and a thickened base is fixedly connected to the bottom of the vibration mechanism. A first discharge port and a second discharge port are located on both sides of the body, and an adhesive material conveying mechanism is located at the bottom of both the first and second discharge ports. The adhesive material conveying mechanism includes a conveying pipe inserted into the inner walls of the first and second discharge ports. Openings are formed on the front and back of the first and second discharge ports, and pressing blocks are inserted into the inner walls of the openings. This invention combines the first and second discharge ports of the purification device with the adhesive material conveying mechanism. The conveying pipe facilitates the transport of impurities and filtered adhesive, preventing environmental pollution. In the process of developing this invention, the inventors discovered the following problems with the existing technology:

[0004] Existing impurity removal equipment used in rubber adhesive production relies on intermittent manual operation during the material injection process, requiring frequent injection of adhesive material into the equipment body, making it difficult to achieve continuous and automated feeding. This inefficient injection mode reduces material conveying efficiency. In addition, the use of a single filter screen for filtration makes the filter screen prone to clogging, resulting in reduced impurity removal efficiency.

[0005] Therefore, a purification device for rubber adhesive production is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a purification device for the production of rubber adhesives to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a purification device for rubber adhesive production, comprising an injection hopper, two support seats fixedly installed on the outer surface of the injection hopper, an electromagnetic chip collecting plate below the injection hopper, a screening screen plate below the electromagnetic chip collecting plate, an injection assembly above the injection hopper, two vibration assemblies outside the screening screen plate, an adhesive material conveyor below the screening screen plate, the injection assembly including a variable frequency motor fixedly installed on the upper surface of the injection hopper, a drive shaft fixedly installed at the output end of the variable frequency motor, a spiral feeding blade fixedly installed at the output end of the drive shaft, an injection electric valve fixedly connected to the outer surface of the bottom end of the injection hopper, a fixing plate fixedly installed on one side of each of the two support seats that are close to each other, and the other side of each of the two fixing plates that are close to each other being fixedly installed on the outer surface of the electromagnetic chip collecting plate.

[0008] Preferably, both vibration components include sliding blocks fixedly installed on the outer surface of the screening screen, and sliding holes are opened on the side of the two support seats that are close to each other. The outer surfaces of the two sliding blocks are slidably connected to the inner walls of the two sliding holes, and drive motors are fixedly installed on the side of the two sliding blocks that are far from each other.

The top ends of the two springs are respectively fixedly installed on the bottom surface of the two sliding blocks.

[0010] Preferably, the upper surface of the injection hopper is fixedly connected to an injection pipe, and a sealing plug plate is provided above the injection pipe.

[0011] Preferably, the adhesive material conveyor includes a conveyor belt located below the screening screen, a geared motor is fixedly mounted on the outer surface of one of the support seats, a drive roller is fixedly mounted on the output end of the geared motor, and the outer surface of the drive roller is connected to the inner ring of the conveyor belt.

[0013] Preferably, a mounting base plate is fixedly installed on the bottom surface of both support seats, and mounting holes are opened on the bottom surface of both mounting base plates. A controller is fixedly installed on the outer surface of one of the support seats.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this impurity removal equipment for rubber adhesive production achieves continuous and automated injection of rubber adhesive materials through the cooperation of a variable frequency motor, drive shaft, and spiral feeder in the injection assembly, combined with an electric injection valve. This changes the inefficient mode of traditional intermittent manual injection, improves material conveying efficiency, and effectively removes ferromagnetic impurities and other impurities through the dual impurity removal design of electromagnetic chip collection plate and vibrating screening screen, thus improving the impurity removal effect.

[0016] Compared with existing technologies, this impurity removal equipment for rubber adhesive production drives the drive roller to rotate via a geared motor, which in turn drives the conveyor belt to transport the rubber adhesive material after impurity removal by the screening screen to the subsequent processing station. This ensures that the impurity-removed rubber adhesive material is smoothly transported to the next stage, thereby reducing the conveying efficiency of the rubber adhesive material.

[0023] 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. Example

[0024] As attached Figures 1-5 The device shown is a debris removal device for rubber adhesive production, including a feeding hopper 1. Two support seats 2 are fixedly installed on the outer surface of the feeding hopper 1. An electromagnetic chip collecting plate 3 is provided below the feeding hopper 1. The working principle of the electromagnetic chip collecting plate 3 is based on electromagnetic induction and magnetic attraction. When the electromagnetic chip collecting plate 3 is powered on, current flows through the internal coil. According to the principle of electromagnetic induction, the energized coil will generate a magnetic field around it. The iron core is magnetized under the action of the magnetic field, thereby making the entire electromagnetic chip collecting plate 3 generate strong magnetism. When rubber adhesive material containing ferromagnetic impurities is discharged from the feeding hopper 1, the chip collecting plate 3 can be removed. As bucket 1 falls and passes over electromagnetic chip collecting plate 3, ferromagnetic impurities are attracted to the surface of electromagnetic chip collecting plate 3 under the influence of the magnetic field. During cleaning, the power supply to electromagnetic chip collecting plate 3 is typically cut off, de-energizing the coil and eliminating the magnetic field. Consequently, the magnetism of the iron core also disappears, and the attracted ferromagnetic impurities lose their magnetic force and can be easily removed from the surface of electromagnetic chip collecting plate 3. A screening screen 4 is located below electromagnetic chip collecting plate 3, and a feeding assembly 5 is located above feeding hopper 1. Two vibration assemblies 6 are located outside the screening screen 4, and an adhesive material conveyor is located below the screening screen 4. 9. The feeding assembly 5 includes a variable frequency motor 501 fixedly mounted on the upper surface of the feeding hopper 1. A drive shaft 502 is fixedly mounted on the output end of the variable frequency motor 501. A spiral feed blade 503 is fixedly mounted on the output end of the drive shaft 502. A feeding electric valve 16 is fixedly connected to the outer surface of the bottom end of the feeding hopper 1. The feeding electric valve 16 is usually composed of a valve body, an electric actuator, a control module, etc. In this rubber adhesive production impurity removal equipment, its working principle is as follows: when the equipment starts to convey materials, the controller 13 sends a control signal, and the electric actuator receives it. Upon receiving the signal, the electric actuator typically includes components such as a motor and a transmission device, which in turn drive the valve core inside the valve to move. When the valve core moves to the open position, the rubber adhesive material in the hopper 1 can smoothly pass through the electric valve 16 under the push of the spiral feeder 503 and be conveyed downwards to the subsequent electromagnetic chip collection plate 3 and screening screen 4 for impurity removal. The two support seats 2 are fixedly installed with fixing plates 12 on their sides that are close to each other, and the two fixing plates 12 are fixedly installed with the outer surface of the electromagnetic chip collection plate 3 on their sides that are close to each other.

[0025] As can be seen from the above description, this utility model has the following beneficial effects: through the cooperation of the variable frequency motor 501, drive shaft 502 and spiral feeding blade 503 in the injection component 5, combined with the injection electric valve 16, the continuous and automated injection of rubber adhesive material is realized, which changes the inefficient mode of traditional intermittent manual injection and improves the material conveying efficiency. In addition, the dual impurity removal design of electromagnetic chip collecting plate 3 and vibrating screening screen plate 4 can effectively remove ferromagnetic impurities and other impurities. The adhesive material conveyor 9 ensures that the impurity-removed material is smoothly conveyed to the subsequent stage. Example

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0027] like Figures 1-5 As shown, in a preferred embodiment, both vibration components 6 include sliding blocks 601 fixedly mounted on the outer surface of the screening mesh plate 4. Sliding holes 602 are provided on the sides of the two support bases 2 that are close to each other. The outer surfaces of the two sliding blocks 601 are slidably connected to the inner walls of the two sliding holes 602. Drive motors 603 are fixedly mounted on the sides of the two sliding blocks 601 that are far apart from each other. Eccentric vibration blocks 604 are fixedly mounted on the output ends of the two drive motors 603. Fixing blocks 7 are fixedly mounted on the sides of the two support bases 2 that are close to each other. Springs 8 are fixedly mounted on the upper surfaces of the two fixing blocks 7. The tops of the two springs 8 are fixedly installed on the bottom surfaces of the two sliding blocks 601 respectively. Furthermore, the sliding blocks 601 and the sliding holes 602 cooperate to achieve sliding guidance. In addition, the drive motor 603 drives the eccentric vibrating block 604 to rotate and generate vibration, which can make the screening screen plate 4 vibrate at high frequency, which can accelerate the material passing through the screening screen plate 4, effectively prevent impurities from accumulating and clogging the screen, and improve screening efficiency. The support structure composed of the fixed block 7 and the springs 8 plays a supporting role when the screening screen plate 4 vibrates, and ensures that the vibration process is stable, avoiding the impact of excessive vibration amplitude on the stability and service life of the equipment.

[0028] like Figures 1-5As shown, in a preferred embodiment, a material injection pipe 10 is fixedly connected to the upper surface of the injection hopper 1, and a sealing plug plate 11 is provided above the injection pipe 10. The adhesive material conveyor 9 includes a conveyor belt 901 located below the screening screen plate 4. A reduction motor 902 is fixedly installed on the outer surface of one of the support seats 2, and a drive roller 903 is fixedly installed at the output end of the reduction motor 902. The outer surface of the drive roller 903 is connected to the inner ring of the conveyor belt 901. Bearings 904 are fixedly embedded on the side of the two support seats 2 that are close to each other. The inner rings of the two bearings 904 are rotatably connected to the outer surfaces of both ends of the drive roller 903. Mounting base plates 14 are fixedly installed on the bottom surface of the two support seats 2, and mounting holes 15 are opened on the bottom surface of the two mounting base plates 14. The outer surface of one of the support seats 2 is... A controller 13 is fixedly installed on the surface. Furthermore, the material is conveniently injected into the material hopper 1 through the injection pipe 10, while the sealing plug plate 11 can seal the injection pipe 10 when no material is being injected. The drive roller 903 is driven to rotate by the geared motor 902, which can drive the conveyor belt 901 to operate. The material after impurity removal by the screening screen 4 can be transported to the subsequent processing station. The bearing 904 reduces the frictional resistance when the drive roller 903 rotates, ensuring the stable operation of the conveyor belt 901. The mounting base plate 14 and mounting holes 15 are used to fix the equipment in the working site, enhancing the stability of the equipment. The controller 13 can uniformly control the various components of the equipment, such as adjusting the speed of the variable frequency motor 501, the vibration frequency of the drive motor 603, controlling the opening and closing of the injection electric valve 16, and the start, stop and speed of the adhesive material conveyor 9.

[0029] The working process of this utility model is as follows:

[0030] In the later stages of use, the impurity removal equipment used for rubber adhesive production first injects the rubber adhesive material into the injection hopper 1 through the injection pipe 10. Then, the variable frequency motor 501 starts, which drives the drive shaft 502 to rotate the spiral feeder blade 503 and continuously and stably conveys the material in the injection hopper 1 to the bottom. After the material falls from the injection hopper 1, it first passes through the electromagnetic chip collecting plate 3. The electromagnetic chip collecting plate 3 uses electromagnetic force to adsorb ferromagnetic impurities in the material, thus initially removing some of the impurities.

[0031] The material then falls onto the screening screen 4. The drive motor 603 drives the eccentric vibrating block 604 to rotate, which generates vibration and causes the screening screen 4 to vibrate, thereby screening out impurities from the material. After the impurities are removed, the material falls onto the conveyor belt 901 below after passing through the screening screen 4. The drive roller 903 is driven by the geared motor 902 to rotate, which causes the conveyor belt 901 to move to the left, transporting the material to the subsequent processing stage. This is the working process and working principle of the device.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
