Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, specifically a high-temperature resistant composite plastic particle cooling and shaping machine. Background Technology

[0002] Composite plastic particles are widely used in packaging materials, automotive parts, building structures, and functional modified materials. During their production, the particles, after high-temperature extrusion molding, typically require rapid cooling to ensure intact particle shape, dimensional stability, and uniform release of internal stress. The quality of cooling directly affects subsequent processing performance and product consistency. Therefore, developing efficient and stable cooling and shaping equipment is a key aspect of ensuring product quality.

[0003] Currently, common cooling and shaping devices in the industry mainly adopt horizontal conveyor belts + air-cooled units or water tank cooling modes. For example, a typical structure involves conveying high-temperature particles via belt into multiple fan blowing areas or water spray areas for cooling. This structure has a certain cooling function, but it has the following main problems during use: Low cooling efficiency: The cooling method using fixed-position fans or water nozzles results in poor temperature uniformity, and uneven heating and cooling may occur on the outer surface of the particles, making it difficult to achieve rapid shaping.

[0004] Poor material tumbling and many cooling dead zones: Most existing equipment is a planar conveying structure, where particles are cooled on only one side, resulting in uneven heating, slow overall cooling rate, and easy agglomeration or adhesion.

[0005] The spray system and the air-cooling structure are separated, resulting in poor coordination: spraying and air cooling are often arranged as independent equipment, making it impossible to accurately coordinate the cooling path according to the particle motion trajectory, which leads to high energy consumption and complex control.

[0006] In summary, existing plastic particle cooling devices still have significant shortcomings in terms of structural linkage, cooling path control, efficiency improvement, and equipment maintenance, making it difficult to meet the current demand for large-scale, high-quality, and high-efficiency cooling and shaping of high-performance plastic particles. Therefore, there is an urgent need for a composite plastic particle cooling and shaping device that is compact in structure, highly efficient in cooling, has strong linkage, and is easy to clean and maintain, in order to improve the overall process stability and automation level. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, this utility model provides a high-temperature resistant composite plastic particle cooling and shaping machine, which uses roller tumbling conveying combined with spray cooling and blower-assisted cooling, and is equipped with a special cleaning structure and efficient transmission linkage mode to achieve efficient cooling, automatic cleaning and uniform shaping of particles.

[0009] This utility model cooling and shaping machine mainly includes: a water tank base, rollers, spray pipe assembly and cooling air blower. It has a compact structure, coordinated functions, high temperature adaptability and continuous operation capability, and is suitable for online cooling and shaping of plastic particles.

[0010] In a preferred embodiment, the overall cooling and shaping machine includes a water tank base, rollers, a spray pipe assembly, and cooling blowers. The top surface of the water tank base is provided with two sets of symmetrically arranged bearing wheels and wing plates. The rollers have bearing rings at both ends that contact the bearing wheels. The rollers have a mesh-like hollow structure, suitable for particle tumbling and penetration cooling. The spray pipe assembly is fixed to the surface of the wing plates and is supplied with coolant by a circulating pump, which is drawn into the spray system from the bottom of the water tank. The rollers rotate through a friction connection with the bearing wheels, driven by a geared motor mounted on the surface of the water tank. Two sets of cooling blowers are installed inside the water tank to provide lateral airflow assistance for cooling the roller surface.

[0011] Specifically, this structure achieves efficient shaping of composite plastic particles through friction drive between the bearing wheel and the roller bearing ring, roller tumbling material transfer, and dual cooling of spraying and blowing, making it suitable for continuous batch operation.

[0012] In a preferred example, the wing plates are symmetrically arranged on both sides of the drum: the ends of the spray pipe assembly are provided with multiple spray nozzles, which are structurally evenly distributed and the nozzles are arranged radially toward the outer surface of the drum, and the coolant spray path directly covers the outer wall of the drum.

[0013] Specifically, the radial spraying method ensures uniform cooling of plastic particles and synchronous temperature drop inside and outside the mesh structure, solving the problem of uneven distribution of the traditional linear cooling flow field and improving the consistency of particle shaping.

[0014] In a preferred example, a cleaning brush is provided at the top of the wing plate: the cleaning brush is mounted directly above the roller, with the bristles pressing down to contact the roller surface. As the roller rotates, the cleaning brush continuously acts on its surface to remove residual plastic particles or other impurities embedded in the mesh.

[0015] Specifically, this cleaning structure ensures that the channels on the roller surface remain open at all times, effectively preventing blockage or thermal blockage, improving equipment cooling efficiency and continuous operation stability, and reducing maintenance frequency.

[0016] In a preferred example, a feed hopper and a discharge hopper are installed at both ends of the water tank base. Both the feed hopper and the discharge hopper are arranged at an angle and open towards the inside of the drum. High-temperature particles enter the drum from the feed hopper, and after cooling, they are automatically discharged from the tail end of the drum into the discharge hopper, realizing the integration of cooling and discharge processes.

[0017] Specifically, this arrangement optimizes the material flow path, reduces the risk of material backflow, and improves the continuity of cooling and the automation of particle output.

[0018] In a preferred example, the geared motor is connected to the bearing wheel drive: the output end of the geared motor drives the bearing wheel to rotate, and indirectly drives the drum to rotate through the frictional contact between the bearing wheel and the bearing ring. The transmission structure is simple and the motion synchronization is high.

[0019] Specifically, this structure eliminates the need for roller bearings and chain drive mechanisms, reduces moving parts, lowers the failure rate and energy consumption, and improves the stability and ease of maintenance of the equipment's transmission system.

[0020] In a preferred example, the cooling blower includes a volute and a blower: the blower is disposed inside the volute and connected to a motor, and is driven by the motor to rotate to generate airflow. The air outlet of the volute is arranged in a radially opposing roller configuration, and the generated airflow blows directly onto the outer surface of the roller.

[0021] Specifically, the blower creates a directional cold air flow field, further enhancing the cooling effect on the surface of the drum and the particles inside. Combined with the spray system, it achieves "dual-path cooling," shortening the particle cooling time and improving the overall cooling efficiency.

[0022] In summary, this utility model solves the problems of low cooling efficiency, difficult cleaning, and complex transmission in existing particle cooling equipment through structural integration and functional synergistic design, and realizes efficient cooling, automatic cleaning and stable shaping of composite plastic particles, with good adaptability and industrial applicability.

[0023] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting the roller and bearing wheel to contact and drive with a geared motor, the roller can rotate at a uniform speed. Combined with the spray pipe assembly and cooling blower, the high-temperature plastic particles are cooled in two ways, which not only achieves effective cooling of the particles, but also improves the cooling efficiency, ensuring that the particles are shaped completely and have stable quality.

[0024] 2. In this utility model, by setting a cleaning brush to clean the surface of the roller in real time, the problem of plastic particles getting stuck in the roller mesh is solved, the roller maintains good ventilation and spray penetration, and the continuous operation of the equipment and the reliability of the cooling system are improved.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-temperature resistant composite plastic particle cooling and shaping machine.

[0030] Combination Figures 1-4 As shown, the present invention provides a high-temperature resistant composite plastic particle cooling and shaping machine, which includes a water tank base 100, a roller 200, a spray pipe assembly 300, and a cooling blower 400.

[0031] The water tank base 100 is an integral support structure, with mounting positions for supporting and driving other functional components. On the top surface of the water tank base 100, two sets of symmetrically arranged bearing wheels 101 and wing plates 102 are provided. The two sets of bearing wheels 101 are respectively located at both ends of the roller 200, forming a contact support relationship with the bearing ring 210 of the roller 200, realizing the axial support and rotational guidance functions of the roller 200. The wing plates 102 are rigidly connected to the water tank base 100 and are located on both sides of the roller 200, having structural surfaces for installing the spray pipe assembly 300 and the cleaning brush 120.

[0032] The roller 200 is a hollow cylindrical structure with a metal mesh surface to facilitate the flow of cooling medium. Both ends of the roller 200 are provided with bearing rings 210, which are supported on the surface of the bearing wheel 101 and rotate through friction. To achieve rotational drive, a reduction motor 110 is provided on one side of the water tank base 100, whose output shaft is connected to the bearing wheel 101. This, in turn, drives the roller 200 to rotate at a uniform speed through the contact between the bearing wheel 101 and the bearing rings 210.

[0033] The spray pipe assembly 300 is a collection of multiple hollow pipe units, fixedly installed on the outer surface of the wing plate 102. The end of the spray pipe assembly 300 has multiple evenly distributed spray nozzles, arranged radially towards the outer surface of the roller 200, facilitating liquid spray cooling of the plastic particles inside the roller 200. One end of the spray pipe assembly 300 is connected to a circulating pump 310, the inlet of which is connected to the bottom cavity of the water tank base 100, used to draw coolant and send it into the spray pipe assembly 300, thus forming a closed-loop circulating spray cooling system.

[0034] like Figure 2 and Figure 3 As shown, a cleaning brush 120 is also fixedly installed at the top of the wing plate 102. The cleaning brush 120 is positioned directly above the roller 200 and brushes its outer surface as the roller 200 rotates. Since the outer surface of the roller 200 has a mesh structure, some high-temperature plastic particles may become stuck inside the mesh during the cooling process. The cleaning brush 120 can effectively remove the residue, prevent clogging, and maintain the cleanliness and permeability of the roller surface.

[0035] The water tank base 100 has a feed hopper and a discharge hopper at both ends, which are arranged at an angle and open toward the inner cavity of the roller 200 to facilitate the introduction and discharge of materials. High-temperature plastic particles are introduced into the roller 200 through the feed hopper, and continuously tumble and move under the rotation of the roller, while being sprayed and air-cooled. After cooling and molding, they are discharged from the discharge hopper.

[0036] like Figure 3 As shown, the output end of the geared motor 110 is connected to the bearing wheel 101 via a transmission shaft, and the bearing wheel 101 and the bearing rings 210 at both ends of the roller 200 form a contact transmission structure. Driven by the geared motor 110, the bearing wheel 101 rotates and drives the bearing rings 210 through friction, causing the roller 200 to rotate uniformly around the axis.

[0037] like Figure 4 As shown, the cooling blower 400 includes a volute 410 and a blower 420, with the blower 420 rotatably mounted inside the volute 410. A motor 411 is located on one side of the volute 410, driving the blower 420 to rotate at high speed to generate airflow. The air outlet of the volute 410 is located on its side, arranged radially towards the outer wall of the drum 200. High-pressure cold air is blown onto the outer surface of the drum 200 through the air outlet of the volute 410, further assisting the spray cooling process and improving the overall cooling efficiency.

[0038] In operation, the structure described in this invention allows high-temperature plastic particles to enter the drum 200 from the feed hopper. The rotating drum tumbles and conveys the particles, while the combined action of the spray pipe assembly 300 and the cooling blower 400 achieves rapid cooling. Residue on the drum surface is removed in real-time by the cleaning brush 120, and the finished product is discharged from the outlet hopper. The machine has a compact structure, stable operation, and is suitable for shaping and cooling plastic particles within different particle sizes and temperature ranges.

[0039] Working principle and usage process of this utility model: This invention achieves rapid cooling and shaping of high-temperature plastic particles through a combination of roller rotation, spray cooling, and blower cooling. Its core lies in integrating multiple functional modules onto a single water tank base, forming a closed-loop, interconnected cooling system.

[0040] Drum rotation drive: The geared motor 110 drives the bearing wheel 101 to rotate. The bearing wheel is driven by friction with the bearing rings 210 at both ends of the drum, so that the drum 200 rotates at a constant speed around the axis.

[0041] Particle conveying and surrounding cooling: High-temperature composite plastic particles fall into the drum through the feed hopper and roll forward inside the drum as it rotates. The surface of the drum has a mesh structure, which facilitates the penetration of external sprayed coolant and blower air.

[0042] Spray cooling system: Spray pipe assembly 300 is arranged on the wing plates 102 on both sides of the drum circumference, with the spray nozzle facing the center of the drum. Circulation pump 310 draws water from the bottom of water tank base 100 to the spray pipe to achieve uniform liquid cooling of high temperature particles.

[0043] Cooling blower assisted cooling: The cooling blower 400 is set below or on both sides of the drum. The volute 410 drives the blower 420 to rotate through the motor 411, generating cold air that blows radially onto the surface of the drum 200, enhancing cooling efficiency and preventing water vapor accumulation.

[0044] Cleaning structure function: The cleaning brush 120 is set above the roller. As the roller rotates, it brushes away residual or stuck plastic particles on its surface, preventing material from adhering and clogging the mesh, and maintaining permeability and cleanliness.

[0045] Finished product discharge: The cooled particles slide out through the discharge hopper at the other end of the drum, completing the entire cooling and shaping process.
