Description

Technical Field

[0001] The invention relates to the technical field of bamboo-plastic composite processing, in particular to a bamboo-plastic composite material processing device. Background Art

[0002] Bamboo plastic composite material is a composite material that uses bamboo fiber as the main filling material and is processed and formed with a plastic matrix (usually polyethylene, polypropylene, polyvinyl chloride, etc.) through a certain process. Bamboo plastic composite materials have good environmental performance, high strength, durability and excellent corrosion resistance. The main raw materials of bamboo plastic composite materials include bamboo powder or bamboo fiber, plastic resin, additives, etc. Bamboo powder or bamboo fiber usually needs to be dried to ensure that its moisture content is within a reasonable range (generally controlled within 3%), otherwise it will affect the uniformity and physical properties of the composite material. In addition, plastic resins usually use low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP) or polyvinyl chloride (PVC), etc. In the internal mixer, bamboo powder / bamboo fiber is mixed with plastic resin and other additives and fully plasticized and reacted. The working principle of the internal mixer is to mix the raw materials through the high shear force generated by two relatively rotating rubber rollers or spiral blades. In this process, bamboo fiber and plastic resin form a good physical combination, so that bamboo fiber can be evenly dispersed in the plastic matrix, thus forming a stable composite structure. The bamboo-plastic composite after mixing is sent to the screw extruder for further processing. In the screw extruder, the bamboo-plastic composite is melted under the combined action of temperature and pressure, and is formed into the desired shape through a mold. The bamboo-plastic composite material after extrusion is usually in the shape of strips or plates, and the formed bamboo-plastic composite material needs to be cooled to ensure its shape stability and achieve the required physical properties. At present, the extruded strip bamboo-plastic composite material needs to be introduced into a conveyor line, and a number of fans continuously arranged on the conveyor line blow air to the strip bamboo-plastic composite material so that the strip bamboo-plastic composite material can be cooled and formed. However, there is a blasting blind area between adjacent fans in the process, and the material cannot obtain sufficient air flow when passing through, resulting in the strip bamboo-plastic composite material in the conveying process not being blasted when passing through the area. In addition, since the temperature of the strip bamboo-plastic composite material itself is relatively high, the fan circulates hot air, and the circulated hot air will cause further heat preservation and temperature rise of the material, forming a vicious circle. Summary of the invention

The supporting roller 503 is a stainless steel roller, double-tube multi-row water-cooled The pipeline of the cooling module 7 is located between the supporting roller 503 and the cooling fan 11.

[0019] Embodiment 3, based on embodiment 2, Figure 7It is given that the swing arm type gear rack reciprocating transmission assembly 13 includes a hollow frame 1301 fixed on one side of the surface of the conveying frame 4, a main shaft 1302 rotatably installed on one side of the inner part of the hollow frame 1301, a swing arm body 1304 rotatably installed on one side of the surface of the hollow frame 1301, and an I-shaped slide plate 1307 slidably installed on one end of the surface of the hollow frame 1301, a turntable 1303 is fixed to one end of the surface of the main shaft 1302, a first convex column 1305 penetrating to the outside of the swing arm body 1304 is installed at the edge position of the surface of the turntable 1303, and a straight groove for the first convex column 1305 to penetrate out is provided at one end of the surface of the swing arm body 1304; The other end of the main shaft 1302 is equipped with a belt transmission structure 1306 for connecting to the output shaft of the stepper motor, a second boss 1308 is fixed on the side of the surface of the I-shaped skateboard 1307, and a U-shaped notch is provided at the top of the swing arm body 1304 for the second boss 1308 to pass through. A gear rack transmission structure 1309 for driving one of the rotating shafts 9 to rotate is installed on the back of the I-shaped skateboard 1307. The gear rack transmission structure 1309 includes a convex seat fixed on the back of the I-shaped skateboard 1307, a rack installed on the top of the convex seat, and a driven gear fixed on one end of one of the rotating shafts 9. The driven gear and the rack are meshed with each other. A notch groove for the belt transmission structure 1306 is provided on the outer wall of one side of the hollow frame 1301; The main shaft 1302 drives the turntable 1303 to rotate. Since the first boss 1305 is located in the straight groove of the swing arm body 1304, the rotational motion of the main shaft 1302 is converted into the reciprocating swinging motion of the swing arm body 1304.

[0020] Embodiment 4, based on embodiment 3, Figure 8It is given that the double-tube multi-row water-cooling module 7 includes a frame 701 fixed on the outer wall of one side of the conveying frame 4, a conveying pump 702 installed at the bottom of the frame 701, and a Y-type double-way liquid inlet pipe group 703 installed on the liquid outlet of the conveying pump 702. One side of the interior of the conveying frame 4 is provided with a Y-type double-way liquid discharge pipe group 706 corresponding to the Y-type double-way liquid inlet pipe group 703. Two straight pipes 704 are installed between the Y-type double-way liquid discharge pipe group 706 and the Y-type double-way liquid inlet pipe group 703. The straight pipe 704 and the longitudinal pipe 705 are located between the cooling fan 11 and the Y-type double-way liquid inlet pipe group 703. A plurality of longitudinal pipes 705 are installed at equal intervals between the two straight pipes 704. The delivery pump 702 delivers external cold water to the Y-shaped double-pass liquid inlet pipe group 703. The Y-shaped double-pass liquid inlet pipe group 703 delivers the cold water to the two straight pipes 704 in a diverted manner. The longitudinal pipes 705 connect the two straight pipes 704 and further disperse the water flow. The water flow after heat exchange is collected in the Y-shaped double-pass liquid discharge pipe group 706 and discharged through the switch valve 707. The water flow circulates through the double pipes, which can quickly take away the heat generated by the material during the processing, and effectively prevent the performance degradation caused by overheating of the material. The extension direction of the central axis of the longitudinal tube 705 is perpendicular to the extension direction of the central axis of the straight tube 704. A switch valve 707 is installed at the bottom end of the Y-type double-way drainage pipe group 706. The setting of the longitudinal tube 705 can achieve a larger cooling area in a smaller space, thereby improving the cooling efficiency.

[0021] When the embodiment of the present application is used, the bamboo-plastic composite material is firstly mixed in an internal mixer to ensure uniform dispersion of the bamboo powder and the plastic resin. The high temperature and high pressure working environment of the internal mixer allows the material to reach a certain molten state, thereby improving the fluidity of subsequent processing. The material is then fed into the screw extruder 2 for further processing and molding. In the screw extruder 2, the temperature is further increased, and the material will have a high-temperature molten state during the extrusion process to reach the required processing temperature and fluidity. The bamboo-plastic composite material is in a strip shape after coming out of the screw extruder 2, and needs to enter the subsequent sideband type multi-roller feeding module 5. The sideband type multi-roller The feeding module 5 is composed of a plurality of rollers, and the strip-shaped bamboo-plastic composite material is horizontally conveyed by the rotation of these rollers. During this process, the staff turns on the rotary drive unit 6 through the PLC control panel 3 to work, and connects the liquid inlet of the double-tube multi-row water-cooling module 7 to the external cold water supply end. At this time, the rotary drive unit 6 makes the rollers in the sideband type multi-roller feeding module 5 rotate synchronously through mechanical transmission to maintain a stable conveying speed, and a part of the rotary power of the rotary drive unit 6 is synchronously transmitted to the swing arm type gear rack reciprocating transmission assembly 13, and the swing arm type gear rack reciprocating transmission assembly 13 is used to drive the X-axis direction. Several cooling fans 11 on the cooling fan 11 swing back and forth together. At this time, each cooling fan 11 can perform effective air circulation at different positions to avoid the problem of insufficient local airflow due to excessive spacing, ensuring the uniform temperature distribution of the material during the transportation process. The double-tube multi-row water-cooling and cooling module 7 is located between the cooling fan 11 and the sideband type multi-roller feeding module 5. The double-tube multi-row water-cooling and cooling module 7, on the one hand, prevents the strip bamboo-plastic composite material from jumping due to air blowing, and on the other hand, the cooling water circulates in each pipe of the double-tube multi-row water-cooling and cooling module 7, taking away the cooling water from the sideband type multi-roller feeding module 5 and the strip bamboo-plastic composite material. The heat effectively reduces the temperature of the feeding area, avoids thermal deformation and strength reduction of the material due to overheating, and due to the continuous flow of cooling water, the water-cooling structure can continuously take away the heat in the air, further reducing the accumulation of high-temperature airflow, and the reciprocating swinging action of the heat dissipation fan helps to ensure the uniform distribution of airflow, avoids the formation of overheating areas and thermal cycles, and when the strip-shaped bamboo-plastic composite material is sent out from the edge band type multi-roller feeding module 5, the cooling process is completed. Later, according to the requirements of the final product, these extruded materials can be further molded, such as injection molding, compression molding, hot pressing, etc. to obtain the desired product shape.
