Description

Technical Field

[0001] The utility model relates to the field of compatibilizer manufacturing, in particular to an anti-clogging compatibilizer screening device. Background Art

[0002] A compatibilizer, also known as a bulking agent or interfacial emulsifier, is an additive that, under the action of intermolecular bonding forces, can promote the combination of two originally incompatible polymers to form a stable blend. This mainly refers to polymer bulking agents. The principle is that the addition of a compatibilizer can reduce the interfacial tension between different polymers, increase the thickness of the interfacial layer, and reduce the size of the dispersed particles, thereby improving the phase structure of the blend and ultimately forming a thermodynamically stable phase with macroscopic uniformity and microscopic phase separation characteristics. After the compatibilizer is manufactured, it must be screened to remove impurities, unqualified particles, and products with uneven particle size distribution generated during the production process, ensuring the purity and uniformity of the compatibilizer, thereby improving the quality and consistency of the final product.

[0003] Regarding the above-mentioned related technologies, the inventors found that the compatibilizer forms particles after extrusion, filtration, and drying, and the particles of the finished material will have large differences in particle size, affecting the quality of the product. Therefore, it is necessary to screen out products that meet the particle size requirements. However, larger particles of compatibilizer will clog the filter of the screening machine, requiring manual opening of the screening machine for unblocking, thereby affecting the screening efficiency. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a compatibilizer screening device which is anti-clogging and does not require opening a screening machine for dredging, and can also improve the screening efficiency of the compatibilizer.

[0005] To solve the above technical problems, the present invention adopts a technical solution: to provide an anti-clogging compatibilizer screening device, comprising: a shell and a feed port opened on the top thereof, a vibration motor installed at the bottom of the shell, an elastic bracket assembly provided below the shell, and a coarse screen, a guide plate and a fine screen installed in the shell from top to bottom in an inclined manner, the bottoms of the coarse screen and the fine screen are respectively connected to a dredging mechanism, and the inclination direction of the guide plate is opposite to that of the coarse screen;

[0006] The end of the shell away from the feed inlet is equipped with a coarse material outlet, a medium material outlet and a fine material outlet in sequence from top to bottom, the lower end of the coarse screen is arranged corresponding to the coarse material outlet, the lower end of the fine screen is arranged corresponding to the medium material outlet, the bottom of the shell cavity is inclined, and the fine material outlet is arranged corresponding to the lower end of the bottom of the shell cavity;

[0007] A driving mechanism for driving the dredging mechanism to move left and right is installed at one end of the shell away from the coarse material outlet.

[0008] By adopting the above technical solution, the vibration motor drives the housing to vibrate, causing the material to jump and move between the coarse and fine screens, accelerating the screening process. The coarse screen is used to initially separate large particles, and the guide plate guides the material flow to the fine screen for further screening. The fine screen is used to separate even smaller particles, and multi-stage screening is achieved, improving screening accuracy and efficiency. During the screening process, the drive mechanism is used to effectively prevent the problems of reduced screening efficiency and shutdown for cleaning caused by screen hole blockage. The automatic operation of the dredging mechanism reduces the need for manual intervention and improves production efficiency and automation level.

[0009] In a preferred example, the present invention can be further configured as follows: the dredging mechanism includes a U-shaped honeycomb panel, a plurality of partitions are provided at intervals on the inner side of the U-shaped honeycomb panel, the partitions divide the inner side of the U-shaped honeycomb panel into a plurality of movable gaps, a plurality of protective rings are provided in the movable gaps, a plurality of rubber balls are provided in the protective rings, the gap between the top of the two ends of the U-shaped honeycomb panel and the bottom of the coarse screen is smaller than the diameter of the rubber ball, the gap between the top of the two ends of the U-shaped honeycomb panel and the bottom of the fine screen is smaller than the diameter of the rubber ball, and rubber pads are connected to both sides of the partitions.

[0010] By adopting the above technical solution, the inner side of the U-shaped honeycomb panel is divided into several movable gaps, which provide movement space for the rubber ball. Driven by the vibration motor, the rubber ball continuously rolls and collides under the screen, effectively cleaning the material residue and blockage in the screen hole. At the same time, the protective ring is used to prevent the rubber ball from falling off or being damaged during the vibration process, and reduce the impact force when the rubber ball directly contacts the screen, thereby extending the service life of the screen.

[0011] In a preferred example, the present invention can be further configured as follows: mounting plates are symmetrically connected to both sides of the bottom of the U-shaped honeycomb panel, and at least two limiting rods are respectively passed through the mounting plates. A spring 1 is respectively mounted on the outer circle of the limiting rod, and one end of the spring 1 is fixedly connected to one side of the shell, and the other end is in contact with the mounting plate.

[0012] By adopting the above technical solution, the mounting plate ensures that the limit rod can be firmly mounted on the U-shaped honeycomb panel and move with it, and under the action of the limit rod, the U-shaped honeycomb panel can move left and right along a predetermined trajectory during vibration, thereby avoiding deviation or shaking caused by excessive vibration, and the spring 1 plays a role of buffering and resetting when the U-shaped honeycomb panel moves.

[0013] In a preferred example, the present invention can be further configured as follows: the driving mechanism includes a driving plate and a connecting rod symmetrically arranged on one side of the shell, one end of the connecting rod is respectively connected to one end of the U-shaped honeycomb panel, and the other end is respectively connected to the driving plate, a servo motor is installed on one side of the shell, and an eccentric wheel assembly is installed on the output shaft of the servo motor, and the outer circle of the eccentric wheel assembly is always in contact with the surface of the driving plate.

[0014] By adopting this technical solution, the connecting rod is responsible for transmitting the power from the drive plate to the U-shaped honeycomb plate, ensuring the synchronous movement between the two. When the servo motor rotates, it drives the outer circle of the eccentric wheel assembly to generate periodic propulsion force on the drive plate, thereby driving the drive plate to perform linear reciprocating motion, which in turn drives the reciprocating movement of the U-shaped honeycomb plate. The inner rubber ball continuously rolls and strikes the coarse and fine screens, improving the efficiency of unclogging the screen. This efficient dredging method helps reduce the time the screen is blocked and improves screening efficiency.

[0015] In a preferred example, the present invention can be further configured as follows: the eccentric wheel assembly includes an eccentric transmission wheel, and a ring array on one side of the eccentric transmission wheel has a plurality of rollers, and the rollers are in contact with the surface of the driving plate in sequence.

[0016] By adopting the above technical solution, when the eccentric transmission wheel rotates, it can drive the roller to contact the surface of the drive plate in turn, reducing the friction resistance and wear between the roller and the drive plate, making the power transmission smoother and more efficient, and also helping to disperse and alleviate the impact force generated by the eccentric transmission wheel on the drive plate, making the force on the drive plate more uniform and stable.

[0017] In a preferred example, the present invention can be further configured as follows: the elastic bracket assembly includes four legs, and reinforcing ribs are respectively connected between two adjacent legs. Spring 2 is installed on the top of the leg, and the top of the spring 2 is respectively connected to the mounting seat, and the mounting seat is respectively connected to the shell.

[0018] By adopting the above technical solution, Spring 2 plays a role of buffering and shock absorption. When the dredging mechanism generates vibration or impact during operation, Spring 2 can absorb and disperse the energy, reduce the impact of vibration on the equipment and the surrounding environment, and improve its screening efficiency.

[0019] In summary, the present invention includes at least one of the following beneficial technical effects of the anti-clogging compatibilizer screening device:

[0020] 1. During the screening process, the vibration motor drives the housing to screen, causing the rubber balls to continuously roll and impact under the coarse and fine screens, effectively clearing material residue and blockages in the screen holes. Protective rings prevent the rubber balls from falling off or being damaged during the vibration process. Simultaneously, the servo motor drives the eccentric wheel assembly to rotate, driving the U-shaped honeycomb panel to reciprocate left and right, effectively driving the rubber balls to impact and clear blocked filter screens at different locations, thus reducing production interruptions caused by downtime for cleaning.

[0021] 2. The vibration motor drives the shell to vibrate, causing the material to jump and move on the coarse screen and the fine screen, accelerating the screening process. The coarse screen is used to initially separate large particles of material, and the guide plate guides the material to flow to the fine screen for further screening. The fine screen is used to separate smaller particles and realize multi-stage screening, thereby improving screening accuracy and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The shell 1 has a plurality of support legs 41, and a plurality of support legs 41 are connected to the support legs 41. A coarse screen 5, a guide plate 6 and a fine screen 7 are installed with an inclined setting. The bottom of the coarse screen 5 and the fine screen 7 are respectively connected to a dredging mechanism 80. The inclination direction of the guide plate 6 is opposite to that of the coarse screen 5. The end of the shell 1 away from the feed port 2 is sequentially installed with a coarse material end outlet 11, a medium material end outlet 12 and a fine material end outlet 13 from top to bottom. The lower end of the coarse screen 5 is corresponding to the coarse material end outlet 11, and the lower end of the fine screen 7 is corresponding to the medium material end outlet 12. The bottom of the inner cavity of the shell 1 is inclined. The outlet 13 is arranged corresponding to the lower end of the bottom of the inner cavity of the shell 1. The end of the shell 1 away from the coarse material outlet 11 is equipped with a driving mechanism 90 for driving the dredging mechanism 80 to move left and right; the coarse material outlet 11, the medium material outlet 12 and the fine material outlet 13 are equipped with corresponding feeding cloth cylinders to transmit the screened compatibilizer to each storage container respectively, and the inner side of each outlet can also be set to be inclined to effectively prevent material accumulation. When the vibration motor 3 drives the shell 1 to vibrate, the material entering the feed port 2 first passes through the coarse screen 5 The coarse screen 5 and the fine screen 7 jump and move to further accelerate the screening efficiency. The coarse screen 5 is used to preliminarily separate large particles. The guide plate 6 guides the material to flow to the fine screen 7 for further screening, thereby extending the screening time of the material. At the same time, the fine screen 7 is used to separate smaller particles and realize multi-stage screening. After the materials of the corresponding particles are screened, the screened compatibilizer is transported to the corresponding storage container through the coarse material end outlet 11, the medium material end outlet 12 and the fine material end outlet 13.

[0036] The dredging mechanism 80 includes a U-shaped honeycomb panel 81, and a plurality of partitions 82 are provided on the inner side of the U-shaped honeycomb panel 81. The partitions 82 divide the inner side of the U-shaped honeycomb panel 81 into a plurality of movable gaps 83. A plurality of protective rings 84 are provided in the movable gaps 83, and a plurality of rubber balls 85 are provided in the protective rings 84. The gaps between the tops of the two ends of the U-shaped honeycomb panel 81 and the bottom of the coarse screen 5 are smaller than the diameter of the rubber balls 85, and the gaps between the tops of the two ends of the U-shaped honeycomb panel 81 and the bottom of the fine screen 7 are smaller than the diameter of the rubber balls 85. Rubber pads 89 are connected to the two sides of the partition 82, and mounting plates 86 are symmetrically connected to the two sides of the bottom of the U-shaped honeycomb panel 81. The mounting plates 86 are respectively provided with different There are less than two limit rods 87, and springs 88 are respectively mounted on the outer circles of the limit rods 87. One end of the spring 88 is fixedly connected to one side of the shell 1, and the other end is in contact with the mounting plate 86; the rubber ball 85 is always located in the protective ring 84.

[0037] The driving mechanism 90 includes a driving plate 91 and a connecting rod 92 symmetrically arranged on one side of the housing 1. One end of the connecting rod 92 is connected to one end of the U-shaped honeycomb plate 81, and the other end is connected to the driving plate 91. A servo motor 93 is installed on one side of the housing 1. The output shaft of the servo motor 93 is installed with an eccentric wheel assembly 94. The outer circle of the eccentric wheel assembly 94 is always in contact with the surface of the driving plate 91. The eccentric wheel assembly 94 includes an eccentric transmission wheel 941. A ring array on one side of the eccentric transmission wheel 941 has several rollers 942, and the rollers 942 are in contact with the surface of the driving plate 91 in turn. When the vibration motor 3 drives the housing 1 to screen, the servo motor 93 synchronously drives the eccentric transmission wheel 941 to rotate, and the driving rollers 942 are in contact with the surface of the driving plate 91 in turn, which not only reduces the friction resistance and wear between the driving plate 91 and the driving plate 91, but also drives the U-shaped honeycomb plate 81 to reciprocate left and right, effectively driving the rubber ball 85 to impact and clear the blocked coarse screen 5 and fine screen 7 at different positions, thereby reducing production interruptions caused by shutdown cleaning.

[0038] The implementation principle of this embodiment is as follows: when in use, after the compatibilizer particles are extruded, filtered and blown dry, the particle material is transported to the feed port 2 along the corresponding conveying device. At this time, the vibration motor 3 vibrates, and the material is screened by the coarse screen 5 in turn, falls to the guide plate 6 for diversion, and is then transported to the fine screen 7 for screening. Under the action of the vibration motor 3, the screening efficiency of the coarse screen 5 and the fine screen 7 is further accelerated. In this process, the rubber ball 85 is also continuously rolled and impacted by the vibration motor 3 to clean the material residue and blockage in the sieve hole. At the same time, the servo motor 93 drives the eccentric wheel assembly 94 to rotate, driving the U-shaped honeycomb plate 81 to reciprocate left and right, so that the rubber ball 85 hits at different positions, clearing the filter holes blocked in different areas, and the screened material is initially separated by the coarse screen 5.
