Description

Technical Field

[0001] This utility model relates to the field of extrusion molding equipment technology, and in particular to a high-efficiency extrusion molding equipment. Background Technology

[0002] Extrusion molding, also known as extrusion or compression molding, is a highly efficient processing method that forces heated and molten polymer materials through a die orifice to form a continuous shape using the squeezing action of a screw or plunger. Its applications range from everyday packaging bags, door and window profiles, and packaging films to drip irrigation systems and greenhouse coverings in agriculture, as well as waterproof membranes and decorative moldings in the construction industry. In the industrial sector, it is more widely used in petrochemical pipeline linings and wear-resistant parts for machinery. Extrusion molding is developing towards higher precision and multi-functionality.

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: the extrusion molding device uses multiple independent motors, such as servo motors, rotary motors, drive motors, stepper motors, etc. The multiple independent motors drive each functional module, which not only increases the overall cost of the device, but also leads to higher overall energy consumption.

[0005] Therefore, those skilled in the art have provided a highly efficient extrusion molding apparatus to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency extrusion molding device. When processing molten plastic, only the second motor needs to be started. The linkage mechanism not only drives the stirring blade to rotate to prevent the molten material from solidifying, but also drives the baffle plate to accelerate the material flow and achieve continuous feeding. This not only reduces the overall cost of the device, but also reduces the overall energy consumption.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A high-efficiency extrusion molding device includes a base, an extrusion hood fixedly mounted on one side of the upper end of the base, a heating storage tank fixedly mounted on the upper end of the extrusion hood, an acceleration mechanism inside the heating storage tank, the acceleration mechanism including a second motor, a lever fixedly mounted on the output end of the second motor, a linkage mechanism mounted on the outer side of the lever near the second motor, a first rotating shaft mounted on one side of the upper end of the linkage mechanism, a first bevel gear fixedly mounted on one side of the first rotating shaft, a second bevel gear rotatably mounted on the upper end of the heating storage tank, and a second rotating shaft fixedly mounted inside the second bevel gear;

[0009] Multiple second spur gears are rotatably mounted on one side of the lower end of the extrusion hood, and multiple first spur gears are rotatably mounted on the side of the lower end of the extrusion hood near the second spur gears. Each of the multiple first spur gears has a cutter fixedly mounted on its lower end. A third motor is fixedly mounted on one side of the lower end of the extrusion hood, and a cooling fan is fixedly mounted on one side of the base.

[0010] Furthermore, the lower end of the second motor is fixedly installed on one side of the heating storage tank, and a limit cover is fixedly installed on one side of the heating storage tank. The linkage mechanism is externally installed inside the limit cover, and the linkage mechanism consists of a synchronous belt and two synchronous pulleys.

[0011] Furthermore, the first bevel gear and the second bevel gear are meshed together, and the externally rotating dial is disposed inside the lower end of the heating storage tank.

[0012] Furthermore, a plurality of stirring blades are fixedly disposed on the outside of the second rotating shaft, and the outside of the plurality of stirring blades is disposed inside the heating storage tank.

[0013] Furthermore, one of the upper ends of the plurality of second spur gears is fixedly mounted at the output end of the third motor, and the plurality of second spur gears and the plurality of first spur gears are meshed together.

[0014] Furthermore, a plurality of solenoid valves are fixedly installed on one side of the lower end of the extrusion hood, and a discharge pipe is fixedly installed at the lower end of each of the plurality of solenoid valves. The upper ends of the plurality of cutters are respectively installed at the lower ends of the plurality of discharge pipes.

[0015] Furthermore, a conveying device is provided on the upper end of one side of the base, and the lower ends of the plurality of discharge pipes are all located on the upper end of the conveying device.

[0016] Furthermore, a first motor is fixedly installed on one side of the upper end of the base, and an extrusion screw is fixedly installed at the output end of the first motor. The extrusion screw is externally rotatably installed inside the extrusion hood.

[0017] This utility model has the following beneficial effects:

[0018] 1. The present invention proposes a high-efficiency extrusion molding device. When molten plastic is processed, it is poured into a heated storage tank. Only the second motor needs to be started to drive the linkage mechanism to operate inside the limiting cover, thereby driving the first rotating shaft and the first bevel gear to rotate. This causes the second bevel gear to rotate, driving the second rotating shaft and the stirring blade to rotate synchronously inside the heated storage tank, thereby achieving continuous stirring of the molten plastic. At the same time, the baffle plate will rotate synchronously at the lower end inside the heated storage tank, accelerating the flow of the molten plastic towards the extrusion cover. Through a single motor, both material solidification can be prevented and material flow can be accelerated, thus improving the conveying efficiency.

[0019] 2. The high-efficiency extrusion molding device proposed in this utility model only requires starting the third motor when cutting materials. Its output end drives the second spur gear to rotate, which in turn drives multiple first spur gears to rotate synchronously, and the cutter at its lower end rotates synchronously. The rotation of the cutter cuts the plastic material discharged from the discharge pipe. The cut material falls into the upper part of the conveyor below. The cooling fan dissipates heat from the molded parts on the conveyor, which can prevent the molded parts from sticking to the conveyor belt. At the same time, it facilitates the subsequent collection of the molded parts. It realizes the synchronous rotation and cutting of multiple cutters and simplifies the transmission structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5 One embodiment provided by this utility model:

[0029] A high-efficiency extrusion molding device includes a base 1, an extrusion hood 3 fixedly mounted on one side of the upper end of the base 1, a heating storage tank 6 fixedly mounted on the upper end of the extrusion hood 3, an acceleration mechanism 5 inside the heating storage tank 6, the acceleration mechanism 5 including a second motor 501, a lever 506 fixedly mounted on the output end of the second motor 501, a linkage mechanism 509 mounted on the side of the lever 506 near the second motor 501, a first rotating shaft 504 mounted on one side of the upper end of the linkage mechanism 509, a first bevel gear 502 fixedly mounted on one side of the first rotating shaft 504, a second bevel gear 503 rotatably mounted on the upper end of the heating storage tank 6, and a second rotating shaft 507 fixedly mounted inside the second bevel gear 503;

[0030] The lower end of the second motor 501 is fixedly installed on one side of the heating storage tank 6. A limit cover 505 is fixedly installed on one side of the heating storage tank 6. The linkage mechanism 509 is externally installed inside the limit cover 505. The linkage mechanism 509 consists of a synchronous belt and two synchronous pulleys. The first bevel gear 502 and the second bevel gear 503 are meshed and connected. The paddle plate 506 is externally rotatably installed inside the lower end of the heating storage tank 6. Multiple stirring blades 508 are fixedly installed on the outside of the second rotating shaft 507. The multiple stirring blades 508 are all externally installed inside the heating storage tank 6. One of the multiple second spur gears 11 is fixedly installed at the output end of the third motor 10. The multiple second spur gears 11 and multiple first spur gears 8 are meshed and connected.

[0031] Specifically, if the material being processed is molten plastic, it can be directly poured into the heating storage tank 6. The heating component inside the tank heats the material, preventing it from cooling and solidifying. The heating component in the heating storage tank 6 uses a ring-shaped electric heating wire embedded in the tank wall and is equipped with a temperature sensor and temperature control module, adaptable to plastic raw materials with different melting points. This is a mature and publicly available technology, therefore, its specific structure and working principle will not be elaborated upon in this article. Subsequently, the second motor 501 is started via the control panel, driving the linkage mechanism 509. The linkage mechanism 509 consists of a synchronous belt and a synchronous pulley. The linkage mechanism 509 will operate within the limiting cover 505, which restricts the linkage mechanism 509, preventing the synchronous belt and synchronous pulley from disengaging, and simultaneously preventing... Dust pollution and foreign object entrapment during synchronous belt operation are prevented, ensuring stable power transmission efficiency. The operation of the linkage mechanism 509 will drive the first rotating shaft 504 and the first bevel gear 502 to rotate. Since the first bevel gear 502 and the second bevel gear 503 are meshed, the rotation of the first bevel gear 502 will drive the second bevel gear 503 to rotate, which in turn will drive the second rotating shaft 507 to rotate, so that the stirring blade 508 will stir inside the heated storage tank 6 to prevent the molten material from solidifying or separating locally. At the same time, the second motor 501 will directly drive the baffle plate 506 to rotate at the lower end of the heated storage tank 6, accelerating the flow of the molten material into the extrusion hood 3 through mechanical thrust, ensuring that the feeding speed and the conveying efficiency of the extrusion screw 13 are dynamically matched to achieve continuous and stable extrusion.

[0032] Reference Figures 1-3 Multiple second spur gears 11 are rotatably arranged on one side of the lower end of the extrusion hood 3. Multiple first spur gears 8 are rotatably arranged on the side of the lower end of the extrusion hood 3 near the second spur gears 11. Each of the multiple first spur gears 8 has a cutter 12 fixedly arranged at its lower end. A third motor 10 is fixedly arranged on one side of the lower end of the extrusion hood 3. A cooling fan 2 is fixedly arranged on one side of the base 1.

[0033] Multiple solenoid valves 14 are fixedly installed on one side of the lower end of the extrusion hood 3. Each of the multiple solenoid valves 14 has a discharge pipe 9 fixedly installed at its lower end. Multiple cutters 12 are respectively installed at the lower end of the multiple discharge pipes 9. A conveying device 7 is installed on the upper side of one side of the base 1. The lower ends of the multiple discharge pipes 9 are respectively installed on the upper end of the conveying device 7. A first motor 4 is fixedly installed on one side of the upper end of the base 1. An extrusion screw 13 is fixedly installed at the output end of the first motor 4. The extrusion screw 13 is externally rotatably installed inside the extrusion hood 3.

[0034] Specifically, during use, first connect the device to an external power source to ensure that the power supply to each motor, solenoid valve 14, and cooling fan 2 is normal. Then, pour plastic raw material into the feed inlet at the top of the heated storage tank 6. The raw material flows naturally into the extrusion hood 3 through the connection between the heated storage tank 6 and the extrusion hood 3, completing the initial feeding. Subsequently, start the first motor 4 on the control panel. Its output end drives the extrusion screw 13 to rotate inside the extrusion hood 3. The extrusion screw 13 gradually compacts and plasticizes the raw material through pushing and shearing actions, and conveys it to the inlet of the multiple sets of solenoid valves 14 at the bottom of the extrusion hood 3. Next, start the third motor 10. Its output end drives a second spur gear 11 to rotate. Since the second spur gear 11 is meshed with the first spur gear 8, the rotation of the second spur gear 11 will drive the first spur gear 8 to rotate synchronously, thereby causing the cutter 12 to rotate in a consistent direction. As the material is extruded through the discharge pipe 9 controlled by the solenoid valve 14 to form a continuous strip, the cutter 12 will cut it to form a molded part of uniform length. The cut finished product falls onto the conveying device 7, which consists of a conveyor belt and a drive motor. The conveyor belt smoothly transports the material to the end for centralized collection, realizing the synchronous conveying and batch processing of multiple sets of materials. At this time, the cooling fan 2 on one side of the base 1 runs continuously to blow air to cool the molded part on the conveying device 7. The temperature of the plastic part that has just been cut is high, and the airflow of the fan can quickly reduce its surface temperature, preventing the molded part from sticking to the conveyor belt due to residual heat. At the same time, it can quickly increase the hardness of the molded part, ensuring the stability of its shape during the conveying process and providing convenience for subsequent collection. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Working principle: When in use, first connect the entire device to an external power source. Then, pour the plastic raw material into the feed port at the top of the heated storage tank 6, allowing the plastic raw material to enter the extrusion hood 3. At this time, start the first motor 4 through the control panel, so that its output end drives the extrusion screw 13 to rotate inside the extrusion hood 3. The extrusion screw 13 conveys the plastic raw material to the multiple sets of solenoid valves 14. Then, start the third motor 10, so that its output end drives the second spur gear 11 to rotate. The rotation of the second spur gear 11 will drive the first spur gear 8 to rotate synchronously, thereby causing the cutter 12 at the lower end of the first spur gear 8 to rotate synchronously. Moreover, the rotation direction of the cutter 12 is the same. The rotation of the cutter 12 cuts and shapes the plastic discharged from the discharge pipe 9. The cut material will fall to the top of the conveying device 7. The conveying device 7 consists of a conveyor belt and a motor. The conveying device 7 discharges the material at its top. The cooling fan 2 continuously dissipates heat from the conveying device 7 to prevent the plastic from sticking together and to cool the plastic at the same time.

[0036] Subsequently, the molten plastic is poured into the heating storage tank 6 for reheating. At this time, the second motor 501 is activated via the control panel, which drives the linkage mechanism 509 to rotate inside the limiting cover 505. The linkage mechanism 509 drives the first rotating shaft 504 to rotate at the upper end of the heating storage tank 6, which in turn drives the first bevel gear 502 to rotate. The rotation of the first bevel gear 502 drives the second bevel gear 503 to rotate, which in turn drives the second rotating shaft 507 to rotate the external stirring blades 508 inside the heating storage tank 6, thereby agitating the molten plastic and preventing it from solidifying. Subsequently, the molten plastic inside the heating storage tank 6 enters the extrusion hood 3 through the deflector 506. Since the deflector 506 is connected to the output end of the second motor 501, it will rotate at the lower end inside the heating storage tank 6, thereby accelerating the movement speed of the molten plastic and achieving continuous conveying of the molten plastic, thus improving the continuity and stability of extrusion.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
