Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic particle cooling and conveying technology, specifically to an anti-sticking device for cooling and conveying engineering plastic particles. Background Technology
[0002] In the field of engineering plastic particle cooling and conveying technology, existing conventional cooling and conveying devices typically include a mounting base, a feed hopper, an inner liner, a conveying assembly, a gas supply assembly, and an air outlet. The feed hopper is installed above the mounting base, the inner liner is fixed inside the mounting base via connectors, the conveying assembly is located inside the inner liner, the gas supply assembly is connected to the side of the mounting base to introduce cooling gas into the inner liner area, and the air outlets are distributed on the side wall of the mounting base to discharge the hot gas after heat exchange. The operation is as follows: engineering plastic particles are fed into the feed hopper and, relying on their own gravity or a simple guiding structure, descend into the inner liner. Then, the conveying assembly is activated, using a spiral feeder to move the particles within the inner liner. Simultaneously, the gas supply assembly introduces cooling gas, which contacts the moving particles through openings in the inner liner, cooling the particles and ultimately completing the particle cooling and conveying process.
[0003] However, existing cooling and conveying devices of this type have significant shortcomings in practical applications. Due to the lack of a dedicated structure for handling particle agglomeration, engineering plastic particles are prone to agglomeration during the feeding process due to their own characteristics or storage environment. Agglomerated particles directly enter the inner cooling stage without treatment, resulting in incomplete cooling of the particles due to uneven contact area between the particle cluster and the external cooling gas. Incompletely cooled particles will stick together during subsequent conveying due to temperature differences or increased surface viscosity, affecting not only the smoothness of particle conveying but also leading to unstable final product quality. At the same time, agglomerated particles may also cause accumulation and blockage in the feed hopper, hindering normal feeding, reducing the overall operating efficiency of the device, and even increasing the load on the conveying components due to blockage, increasing the wear and tear on the motor or screw feeder, and shortening the service life of the equipment. In addition, after agglomeration, particles may also adhere to the inner wall of the inner tank or the surface of the conveying components, which is difficult to clean. Long-term accumulation will further affect the cooling effect and conveying accuracy. These problems all adversely affect the stability and reliability of the cooling and conveying of engineering plastic particles. Utility Model Content
[0004] The problem to be solved by this utility model is to provide a cooling and conveying anti-sticking device for engineering plastic particles. The impact mechanism of this utility model can drive the impact plate to rotate back and forth in the feed hopper, effectively breaking up the clumps of engineering plastic particles during the feeding process, avoiding incomplete cooling due to uneven cooling contact area of the clumps, thereby preventing the particles from sticking together due to uneven cooling, and providing a guarantee for the stable operation of subsequent cooling processes.
[0005] The technical solution provided by this utility model to solve the above problems is as follows: A cooling and conveying anti-agglomeration device for engineering plastic particles includes a mounting base, a feed hopper, an inner liner, an air inlet, a connecting plate, a conveying assembly, an air conveying assembly, and an air outlet. The feed hopper is mounted on the mounting base, the inner liner is mounted inside the mounting base via several connecting plates, the air inlets are evenly distributed on the inner liner, the conveying assembly is installed inside the inner liner, the air conveying assembly is connected to the side of the mounting base, and several air outlets are evenly distributed on the side wall of the mounting base. The device also includes an impact mechanism and a buffer mechanism. The impact mechanism is used to break up agglomerated particles during the feeding of engineering plastic particles to prevent particle agglomeration from affecting the cooling effect, and the buffer mechanism is used to guide and buffer the particles during the breaking up of the engineering plastic particles.
[0006] More preferably, the impact mechanism includes a drive motor, a turntable, a reciprocating rod, guide members, connecting members, a connecting seat, an impact plate, and a guide plate.

[0007] More preferably, the turntable has a protruding rod-like structure on its side, and the middle part of the reciprocating rod is an elliptical frame structure, with the protruding part of the turntable located inside the elliptical frame structure of the reciprocating rod.
[0008] More preferably, the deflector is inclined.
[0009] More preferably, the buffer mechanism includes a contact plate, a damper, a spring, a bonding plate, a torsion spring, and a guide block. The contact plate is slidably connected to the impact plate via symmetrically arranged dampers. The spring is connected between the contact plate and the impact plate.

The symmetrically arranged guide blocks are fixed to the side of the bonding plate.
[0010] More preferably, the bonding plate is inclined and contacts the impact plate.
[0011] Compared with the prior art, the advantages of this utility model are: the impact mechanism of this utility model can drive the impact plate to rotate back and forth in the feed hopper, effectively breaking up the agglomerated engineering plastic particles during the feeding process, avoiding incomplete cooling due to uneven cooling contact area of the agglomerated particles, thereby preventing the particles from sticking together due to uneven cooling, and providing a guarantee for the stable development of the subsequent cooling process.
[0012] The springs and dampers in the buffer mechanism can buffer the impact force of the impact plate on the inner wall of the feed hopper, reduce the noise generated by the impact, and prevent the feed hopper from being damaged by long-term impact, thus protecting the equipment components. The bonding plate and torsion spring work together to deform when the impact plate is about to contact the inner wall of the feed hopper, so as to prevent the movement of the impact plate from being obstructed, ensure the smooth reciprocating rotation of the impact plate, and ensure the continuous stability of the particle dispersing process. In addition, the guide block on the side of the bonding plate can assist in particle guidance, prevent particle conveying from jamming, and ensure smooth material feeding.
[0013] The air inlet of the gas delivery component and the air outlet of the inner liner form a complete cooling airflow circulation. The cooling gas introduced by the gas delivery component enters the inner liner through the air inlet and comes into full contact with the particles, effectively reducing the particle temperature and preventing the particles from sticking together due to high temperature. The hot gas that has completed heat exchange is discharged from the air outlet, ensuring a continuous and stable cooling effect and providing a reliable temperature environment for particle cooling and transportation.

[0025] Example: As shown in the attached figure, an engineering plastic particle cooling and conveying anti-sticking device includes a mounting base 1, a feed hopper 2, an inner liner 3, an air inlet 4, a connecting plate 5, a conveying assembly 6, an air conveying assembly 7, and an air outlet 8. The feed hopper 2 is mounted on the mounting base 1, the inner liner 3 is mounted inside the mounting base 1 through several connecting plates 5, the air inlets 4 are evenly distributed on the inner liner 3, the conveying assembly 6 is installed inside the inner liner 3, the air conveying assembly 7 is connected to the side of the mounting base 1, and several air outlets 8 are evenly distributed on the side wall of the mounting base 1. It also includes an impact mechanism 9 and a buffer mechanism 10. The impact mechanism 9 is used to break up agglomerated particles during the feeding of engineering plastic particles to prevent particle agglomeration from affecting the cooling effect. The buffer mechanism 10 is used to guide and buffer the particles during the breaking up of engineering plastic particles.
[0026] The conveying assembly 6 consists of a motor and a screw feeder, and is capable of conveying engineering plastic particles.
[0027] In this embodiment, the impact mechanism 9 specifically includes a drive motor 91, a turntable 92, a reciprocating rod 93, guide members 94, connecting members 95, a connecting seat 96, an impact plate 97, and a guide plate 98. The drive motor 91 is bolted to the mounting base 1. The turntable 92 is keyed to the output shaft of the drive motor 91. The turntable 92 has a protruding rod-like structure on its side. Several guide members 94 are bolted to the top of the mounting base 1. The reciprocating rod 93 is slidably connected between the several guide members 94. The middle part of the reciprocating rod 93 is an elliptical frame structure. The protruding part of the turntable 92 is located inside the elliptical frame structure of the reciprocating rod 93. The rotation of the turntable 92 drives the reciprocating rod 93 to move laterally back and forth. The impact plate 97 is rotatably connected to the feed hopper 2. The impact plate 97 is used to break up the agglomerated engineering plastic particles to prevent the agglomerated engineering plastic particles from cooling unevenly. The connecting seat 96 is fixed to the side of the impact plate 97. The connecting piece 95 is hinged between the reciprocating rod 93 and the connecting seat 96. The guide plate 98 is fixed to the inner wall of the feed hopper 2. The guide plate 98 is inclined and used to guide the engineering plastic particles.
[0028] Furthermore, the buffer mechanism 10 includes a contact plate 101, a damper 102, a spring 103, a bonding plate 104, a torsion spring 105, and a guide block 106. The contact plate 101 is slidably connected to the impact plate 97 through the symmetrically arranged dampers 102. The contact plate 101 contacts the engineering plastic particles under the action of the impact plate 97. The spring 103 is connected between the contact plate 101 and the impact plate 97 to prevent the particles from impacting the feed hopper 2 during the dispersal of the engineering plastic particles, thereby avoiding vibration and reducing noise caused by impact. The bonding plate 104 is rotatably connected to the contact plate 101. The bonding plate 104 is inclined and contacts the impact plate 97. The bonding plate 104 is used to guide the engineering plastic particles. The torsion spring 105 is connected between the bonding plate 104 and the contact plate 101. The symmetrically arranged guide blocks 106 are fixed to the side of the bonding plate 104.
[0029] Engineering plastic particles are fed into the feed hopper 2. The guide plate 98 fixed to the inner wall of the feed hopper 2 is inclined, which can guide the particles and make them flow smoothly downward along the guide plate 98, avoiding the accumulation and blockage of particles in the feed hopper 2. The drive motor 91 is bolted to the mounting base 1. After the drive motor 91 is started, its output shaft drives the key-connected turntable 92 to rotate. Because the turntable 92 has a protruding rod-shaped structure on its side, and the protruding part is located in the elliptical frame structure in the middle of the reciprocating rod 93, the turntable 92 will drive the reciprocating rod 93 to move laterally back and forth between several guide members 94 when it rotates. The guide members 94 are bolted to the top of the mounting base 1, which can ensure that the reciprocating rod 93 moves stably without deviation. When the reciprocating rod 93 moves laterally back and forth, the connecting seat 96 fixed to the side of the impact plate 97 will move through the hinged connecting member 95, thereby causing the impact plate 97, which is rotatably connected to the feed hopper 2, to rotate back and forth. During the rotation of the impact plate 97, it can break up the clumps of engineering plastic particles in the feed hopper 2, preventing the clumps of particles from entering the subsequent cooling stage due to uneven contact area and resulting in poor cooling effect, effectively avoiding the phenomenon of particle adhesion due to incomplete cooling.
[0030] During the particle dispersion process by the impact plate 97, when the impact plate 97 reciprocates and approaches the inner wall of the feed hopper 2 and is about to stop moving due to contact, the impact plate 97 still tends to continue moving under the driving force of the reciprocating rod 93. At this time, the contact plate 101 on the impact plate 97, which is slidably connected by symmetrically arranged dampers 102, first contacts the inner wall of the feed hopper 2. As the impact plate 97 continues to apply force, the spring 103 connecting the contact plate 101 and the impact plate 97 is compressed. The compression of the spring 103 can initially buffer the impact force. At the same time, the mating plate 104, which is rotatably connected to the contact plate 101, is squeezed by the inner wall of the feed hopper 2. The mating plate 104 and the contact plate 101... The torsion spring 105 connected between them deforms accordingly. The deformation of the torsion spring 105 can not only further absorb the impact energy, but also adapt to the movement trend of the impact plate 97 through its own elastic deformation, so as to avoid the impact plate 97 from being blocked due to direct contact with the inner wall of the feed hopper 2, and ensure the smooth reciprocating rotation of the impact plate 97, so as to continuously and stably disperse the particles. At the same time, the damper 102 can weaken the vibration generated by the impact, avoid the generation of large noise during the impact, and also prevent the feed hopper 2 from being damaged due to long-term impact. The symmetrically arranged guide blocks 106 fixed to the side of the bonding plate 104 can also assist in the guidance of particles, ensure that the particles are smoothly conveyed downward, and avoid the particles getting stuck during the buffering process.
[0031] The dispersed particles smoothly enter the inner liner 3, which is installed in the mounting base 1 via several connecting plates 5. The connecting plates 5 provide stable support for the inner liner 3, preventing it from shifting during subsequent conveying and cooling. The conveying assembly 6 installed inside the inner liner 3 consists of a motor and a spiral feeder. After the conveying assembly 6 is started, the spiral feeder will drive the particles to move evenly within the inner liner 3, achieving stable particle conveying. The air supply assembly 7, which is connected to the side of the mounting base 1, introduces cooling gas into the space between the mounting base 1 and the inner liner 3. The cooling gas enters the inner liner 3 through the evenly distributed air inlets 4 on the inner liner 3, making full contact with the particles conveyed by the conveying assembly 6 to cool and reduce the temperature of the particles, preventing them from sticking together due to excessive temperature. The hot air after heat exchange with the particles is discharged through the evenly distributed air outlets 8 on the side wall of the mounting base 1, forming a complete cooling airflow circulation, ensuring a continuous and stable cooling effect, and ultimately achieving efficient cooling and conveying of engineering plastic particles and preventing sticking.
[0032] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
