Description

Technical Field

[0001] This utility model relates to the field of modified plastic particle homogenization technology, specifically to a modified plastic particle homogenization chamber that prevents bridging. Background Technology

[0002] Modified plastic particle homogenization refers to the process of mixing modified plastic particles from different batches, with different particle sizes, or with different properties using specific equipment and processes, so that they achieve uniformity in physical and chemical properties.

[0003] In the production process of modified plastics, due to factors such as batch differences in raw materials and fluctuations in processing technology, the produced plastic granules may exhibit unevenness in particle size distribution and component ratio. If used directly in subsequent molding processes, this can lead to problems such as inconsistent product performance, differences in strength, and appearance defects. For example, injection molded parts may show localized increased brittleness or uneven color. Therefore, homogenization treatment is a crucial step in ensuring the quality of modified plastic products.

[0004] Because of static electricity on the particle surface or the influence of environmental humidity, agglomeration is prone to occur, leading to bridging structures within the homogenization equipment. Bridging hinders the normal flow and mixing of particles, resulting in insufficient homogenization, and may even cause equipment blockage and interruption of the production process. Currently, traditional homogenization equipment uses a single stirring method, mostly simple rotary stirring, which makes it difficult to achieve omnidirectional particle agitation. The mixing effect of particles from different batches and of different sizes is poor, and the homogenization accuracy is low, failing to meet the production requirements of high-quality modified plastics.

[0005] Therefore, we propose a modified plastic particle homogenization chamber to prevent bridging, in order to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a modified plastic particle homogenization chamber that prevents bridging, in order to solve the problem mentioned in the background art that the particles may agglomerate due to static electricity or the influence of environmental humidity, thus forming a bridging structure in the homogenization equipment, resulting in insufficient homogenization and failing to meet the production requirements of high-quality modified plastics.

[0007] This utility model provides the following technical solution: a modified plastic particle homogenization chamber for preventing bridging, comprising a homogenization chamber body, a homogenization cavity formed inside the homogenization chamber body, a support fixed to the side wall of the homogenization chamber body, a motor fixed to the top surface of the support, a coupling fixedly connected to the output end of the motor, a vibration assembly and a stirring assembly installed on the homogenization chamber body, the stirring assembly comprising a support fixedly connected to the support, a ball bearing rotatably connected inside the support, a stirring rod fixed inside the ball bearing, and a stirring bucket fixed to the bottom of the stirring rod.

[0008] Preferably, the vibration assembly includes a fixed plate fixedly connected to the side wall of the support, a pulley 1 fixedly sleeved on the outer ring of the support, a support block fixed on the side wall of the homogenization chamber, a rotating rod rotatably connected between the support block and the fixed plate, a pulley 2 fixedly sleeved on the outer ring of the rotating rod, and a belt wound between the pulley 1 and the pulley 2.

[0009] Preferably, a connecting plate is fixed to the side wall of the homogenization chamber, a spring is fixed to the side wall of the connecting plate, and a compression plate is fixed to the other end of the spring.

[0010] Preferably, an eccentric wheel is fixedly sleeved on the outer ring of the rotating rod, and the eccentric wheel is on the same circumferential surface as the extrusion plate.

[0011] Preferably, a rotating shaft is fixed to the bottom of the coupling, a crank is fixedly sleeved on the outer ring of the rotating shaft, a sleeve block is fixed to the end side of the crank, and the stirring rod is rotatably connected to the sleeve block.

[0012] Preferably, a small bevel gear is fixed to the outer ring of the stirring rod, and a large bevel gear is fixed to the bottom of the support, with the small bevel gear and the large bevel gear meshing with each other.

[0013] This utility model has the following beneficial effects:

[0014] 1. Through the combined revolution and rotation of the stirring rod, the stirring bucket is driven to tumble the modified plastic particles in the homogenization chamber in all directions. Its revolution trajectory covers the cross section of the homogenization chamber, which can directly impact the particle agglomeration and bridging structure caused by static electricity and humidity. The rotation of the stirring bucket generates shear force in the circumferential direction, which promotes the full interweaving and mixing of plastic particles of different batches and particle sizes. This ensures that the modified plastic particles have stable and consistent performance in subsequent processing and reduces product quality fluctuations caused by uneven particle size.

[0015] 2. By transmitting periodic vibrations to the particles, the adsorption force between particles is reduced, further inhibiting bridging regeneration. This allows for more complete movement between particles, further improving the mixing effect and increasing the efficiency of bridging removal. This effectively avoids production interruptions caused by bridging, ensures continuous production stability, and increases the effective operating time of the equipment.

[0016] 3. The coordinated operation of the mixing and vibration components not only shortens particle mixing time and improves homogenization efficiency, but also eliminates the need for manual intervention to break up bridging and assist mixing, reducing manual operation steps. This not only reduces the labor intensity of workers but also avoids production delays caused by untimely manual handling, thereby reducing labor costs and improving overall production efficiency.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1:

[0025] This embodiment aims to address the problems of production interruptions caused by bridging due to static electricity and humidity during the homogenization process of modified plastic particles, as well as the issues of uneven mixing and low homogenization efficiency between different batches and particle sizes. Please refer to [link to relevant documentation]. Figure 1 - Figure 4This invention provides a technical solution: a modified plastic granule homogenization chamber for preventing bridging, comprising a homogenization chamber body 1 with a conical bottom for easy granule discharge. A homogenization cavity 101 is formed inside the homogenization chamber body 1, which is a hollow cavity consistent with the shape of the chamber body. The inner wall is polished to reduce the adhesion of plastic granules within the chamber. A support 2 is fixed to the side wall of the homogenization chamber body 1, and a motor 3 is fixed to the top surface of the support 2. A coupling 4 is fixedly connected to the output end of the motor 3. A stirring assembly 6 is installed on the homogenization chamber body 1. The stirring assembly 6 includes a support 67 fixedly connected to the support 2, a ball bearing 68 rotatably connected within the support 67, a stirring rod 64 fixed within the ball bearing 68, and a stirring bucket 69 fixed to the bottom of the stirring rod 64.

[0026] A rotating shaft 61 is fixed to the bottom of the coupling 4. A crank 62 is fixedly sleeved on the outer ring of the rotating shaft 61. A sleeve block 63 is fixed to the end side of the crank 62. The stirring rod 64 is rotatably connected to the sleeve block 63. A small bevel gear 65 is fixed to the outer ring of the stirring rod 64. A large bevel gear 66 is fixed to the bottom of the bracket 2. The small bevel gear 65 and the large bevel gear 66 mesh with each other.

[0027] In this embodiment: When homogenizing the modified plastic particles, after starting the motor 3, the output torque is transmitted to the rotating shaft 61 via the coupling 4, and the rotating shaft 61 then drives the crank 62 to rotate synchronously. Because the end of the crank 62 is fixedly connected to the sleeve 63, and the sleeve 63 and the stirring rod 64 form a rotational engagement, the rotation of the crank 62 will drive the stirring rod 64 to move along a circular trajectory. At the same time, the small bevel gear 65 on the outer ring of the stirring rod 64 is engaged with the large bevel gear 66 fixed at the bottom of the bracket 2. During the circular motion of the stirring rod 64, the small bevel gear 65 rolls along the tooth surface of the large bevel gear 66, thereby driving the stirring rod 64 to rotate itself. Under this combined motion of revolution and rotation, the stirring rod 64 synchronously drives the bottom stirring bucket 69 to revolve and rotate within the homogenization chamber 101, while simultaneously driving the ball bearing 68 to rotate flexibly within the support 67, so that the stirring bucket 69 can efficiently stir and homogenize the modified plastic particles in the homogenization chamber 101.

[0028] The revolution trajectory of the stirring bucket 69 covers the horizontal section of the homogenization chamber 101, which can tumble the particles in the chamber in all directions, directly impacting and breaking the particle agglomeration and bridging structure caused by static electricity and humidity; while the rotation of the stirring bucket 69 generates shear force in the circumferential direction, which promotes the full interweaving and mixing of plastic particles of different batches and different particle sizes, improving the homogenization accuracy.

[0029] When local bridging occurs in the bin, the combined motion of the mixing bucket 69 can quickly act on the core area of ​​the bridging, directly breaking the adsorption force between particles through mechanical force, ensuring that the particles fall smoothly. Combined with the mirror polishing treatment of the inner wall of the homogenization bin 1, the friction coefficient between the particles and the bin wall is greatly reduced, further inhibiting the regeneration of bridging. This stirring mode of revolution and rotation can not only shorten the mixing time and improve the particle homogenization efficiency, but also avoid downtime caused by bridging from the root, ensuring the stability of continuous production.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 2:

[0032] This embodiment aims to address the problems of modified plastic granules bridging due to adsorption forces in the homogenization chamber, uneven mixing of granules from different batches and sizes, and poor continuity of homogenization processing due to granule accumulation in the chamber. Please refer to [link to relevant documentation]. Figure 1 - Figure 2 and Figure 5 This invention provides a technical solution: a modified plastic particle homogenization chamber for preventing bridging, comprising a homogenization chamber body 1, a vibration component 5 installed on the homogenization chamber body 1, the vibration component 5 including a fixed plate 51 fixedly connected to the side wall of a support 2, a pulley 52 fixedly sleeved on the outer ring of the support 2, a support block 54 fixedly fixed on the side wall of the homogenization chamber body 1, a rotating rod 53 rotatably connected between the support block 54 and the fixed plate 51, a pulley 55 fixedly sleeved on the outer ring of the rotating rod 53, and a belt 56 wound between the pulley 52 and the pulley 55, the belt 56 being a V-shaped belt made of neoprene rubber, the cross-sectional model of which matches the groove of the pulley, the length of which is determined according to the center distance of the pulleys, having high elasticity and wear resistance, and able to withstand a certain amount of tension and bending.

[0033] A connecting plate 58 is fixed to the side wall of the homogenization chamber 1. A spring 59 is fixed to the side wall of the connecting plate 58. An extrusion plate 510 is fixed to the other end of the spring 59. An eccentric wheel 57 is fixedly sleeved on the outer ring of the rotating rod 53. The eccentric wheel 57 and the extrusion plate 510 are on the same circumferential surface.

[0034] In this embodiment: After the motor 3 starts, while driving the stirring assembly 6 to work, the pulley 52 on the outer ring of the support 2 rotates synchronously with the support 2, and transmits power to the pulley 55 through the belt 56. The pulley 55 drives the rotating rod 53 to rotate under the support of the fixed plate 51 and the support block 54. Since the eccentric wheel 57 is fixedly sleeved on the rotating rod 53, and the eccentric wheel 57 and the extrusion plate 510 are on the same circumferential surface, when the rotating rod 53 drives the eccentric wheel 57 to rotate, the eccentric structure of the eccentric wheel 57 will cause its solid part to periodically extrude the extrusion plate 510. When the eccentric part of the eccentric wheel 57 rotates to the point where it is in contact with the extrusion plate 510, the eccentric part of the eccentric wheel 57 will periodically extrude the extrusion plate 510. When the plates 510 come into contact, they push the extrusion plate 510 away from the homogenization chamber 1. At this time, the spring 59 is stretched. After the eccentric part of the eccentric wheel 57 passes the extrusion plate 510, the spring 59 contracts under its own elastic force, pulling the extrusion plate 510 towards the homogenization chamber 1. This cycle repeats, causing the extrusion plate 510 to drive the homogenization chamber 1 to produce periodic vibrations. This periodic vibration can be transmitted to the modified plastic particles in the homogenization chamber, causing relative movement between the particles, reducing the adsorption force between the particles, and effectively preventing the particles from forming bridges near the chamber wall and inside the chamber. At the same time, the vibration can also assist the stirring component 6 in homogenizing the particles, making the particles from different batches and of different sizes more evenly mixed, further improving the homogenization accuracy. In addition, the vibration can also promote the particles to flow to the bottom of the chamber, avoiding the accumulation of particles in the chamber and ensuring the continuity and stability of the homogenization process.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
