Description

Technical Field

[0001] This utility model relates to the field of PVC plastic profile technology, and in particular to an extrusion molding device. Background Technology

[0002] PVC plastic profile extrusion molding equipment is widely used in industries such as construction, home furnishing, and automobiles. It is mainly used to produce PVC profiles. This equipment transforms PVC resin raw materials into profiles of the required shape through heating and extrusion. It is characterized by high efficiency and stability. With the development of technology, extrusion molding equipment has been continuously optimized, improving production efficiency and product quality, and meeting the material performance requirements of different industries.

[0003] However, existing extrusion molding equipment generally cannot achieve uniform feeding of PVC raw materials to prevent clogging, ensure stable extrusion, and produce molded PVC profiles. First, uneven feeding or clogging of raw materials will cause intermittent supply of raw materials in the barrel, frequent fluctuations in screw extrusion load, and force the equipment to stop frequently to clean the blockage, significantly reducing production continuity, directly lowering the output per unit time, and increasing production time costs. Second, unstable raw material supply will cause imbalance in plasticizing temperature and pressure in the barrel, resulting in defects such as uneven wall thickness, surface depressions, and bubbles in the extruded PVC profiles, increasing the defect rate. This not only wastes raw materials but also requires additional manpower for rework, affecting product delivery quality and corporate reputation. Finally, when raw materials are clogged, the screw is prone to overload operation, which can accelerate wear. The inner wall of the barrel may also be damaged by overheating due to localized raw material retention. Frequent shutdowns for cleaning will also increase the frequency of equipment disassembly and assembly, accelerate the aging of parts, increase equipment maintenance frequency and repair costs, and affect the overall service life of the equipment in the long run.

[0004] Therefore, this utility model proposes an extrusion molding device to solve the above problems. Utility Model Content

A moving plate is slidably connected to the vibration rod. A vibration plate is connected to the moving plate. A telescopic spring is provided on the vibration rod.

[0008] Preferably, a mounting frame is provided on the outer side of the barrel, and a heating plate is provided inside the mounting frame. The heating plate is located on the outer side of the barrel.

[0012] Preferably, a third servo motor is installed on the top side of the hopper near the vibrating motor, and the output end of the third servo motor is connected to a stirring paddle, which is rotatably connected inside the hopper.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, when the device is running, after the PVC raw material is loaded into the hopper, the second servo motor starts, driving the first rotating block, the rotating shaft, and the second rotating block to rotate synchronously. The material-tumbling plate on the rotating shaft rotates accordingly, stirring the raw material in the hopper to prevent clumping and ensure uniform feeding. At the same time, the vibration motor at the bottom of the hopper works, driving the vibration rod to vibrate. The moving plate on the vibration rod, in conjunction with the telescopic spring, drives the vibration plate to vibrate at high frequency, further preventing the raw material from clogging the feed port and ensuring that the raw material enters the barrel stably. Subsequently, the first servo motor starts, driving the screw to rotate inside the barrel to extrude and plasticize the PVC raw material. The plasticized raw material is finally extruded through the extrusion die to form a PVC profile of a specific shape. This achieves uniform feeding and anti-clogging of PVC raw material, ensures stable extrusion, and produces molded PVC profiles. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution:

[0026] This utility model provides an extrusion molding apparatus, including a support base 1 and an extrusion molding assembly 2. The extrusion molding assembly 2 includes a barrel 21 mounted on the top of the support base 1. A first servo motor 22 is mounted on the support base 1 near the barrel 21. The output end of the first servo motor 22 is connected to a screw 23. An extrusion die 24 is connected to the end of the barrel 21 away from the first servo motor 22. The apparatus also includes:

[0027] The feeding uniform anti-blocking component 3 includes a hopper 31 connected to the barrel 21. A second servo motor 32 is installed on the side of the hopper 31 near the top. A first rotating block 36 is provided at the output end of the second servo motor 32. A rotating shaft 37 is connected to the first rotating block 36. A second rotating block 38 is connected to the end of the rotating shaft 37 away from the first rotating block 36. The second rotating block 38 is rotatably connected inside the hopper 31. A tilting plate 39 is connected to the rotating shaft 37. A vibration motor 310 is installed on the side of the hopper 31 near the bottom. A vibration rod 311 is connected to the output end of the vibration motor 310. A moving plate 312 is slidably connected to the vibration rod 311. A vibration plate 313 is connected to the moving plate 312. A telescopic spring 314 is provided on the vibration rod 311.

[0028] In practical applications, when the device is running, after the PVC raw material is loaded into the hopper 31, the second servo motor 32 starts, driving the first rotating block 36, the rotating shaft 37 and the second rotating block 38 to rotate synchronously. The material-tumbling plate 39 on the rotating shaft 37 rotates accordingly, stirring the raw material in the hopper 31 to prevent clumping and ensure uniform feeding. At the same time, the vibration motor 310 at the bottom of the hopper 31 works, driving the vibration rod 311 to vibrate. The moving plate 312 on the vibration rod 311, together with the telescopic spring 314, drives the vibration plate 313 to vibrate at high frequency, further preventing the raw material from blocking the feed port and ensuring that the raw material enters the barrel 21 stably. Then, the first servo motor 22 starts, driving the screw 23 to rotate in the barrel 21 to extrude and plasticize the PVC raw material. The plasticized raw material is finally extruded through the extrusion die 24 to form a PVC profile of a specific shape, realizing uniform feeding and anti-clogging of PVC raw material, ensuring stable extrusion, and producing molded PVC profiles.

[0029] It should also be noted that a mounting bracket 25 is provided on the outside of the barrel 21, and a heating plate 26 is provided inside the mounting bracket 25. The heating plate 26 is located on the outside of the barrel 21.

[0030] Please see Figure 1 , 2 3. The mounting bracket 25 on the outside of the barrel 21 provides fixed support for the heating plate 26. The heating plate 26 is attached to the outer wall of the barrel 21. During operation, it heats the PVC raw material inside the barrel 21 through heat conduction, so that the raw material gradually reaches the plasticizing temperature. In conjunction with the screw 23, the raw material is melted and plasticized, ensuring the material state required for subsequent extrusion molding.

[0031] It should also be noted that after the second servo motor 32 is started, its output end drives the first transmission wheel 33 to rotate, and the second transmission wheel 35 rotates synchronously through the belt 34. By utilizing the stability of the belt 34 transmission, the power is transmitted to the two sets of first rotating blocks 36, realizing the coordinated operation of multiple sets of rotating shafts 37 and tipping plates 39, thereby enhancing the mixing effect of raw materials.

[0032] Please see Figure 1 , 4 After the second servo motor 32 starts, its output drives the first transmission wheel 33 to rotate. Through the belt 34, the second transmission wheel 35 rotates synchronously. Utilizing the stability of the belt 34 transmission, the power is transmitted to the two sets of first rotating blocks 36, realizing the coordinated operation of multiple sets of rotating shafts 37 and tipping plates 39, thereby enhancing the mixing effect of raw materials.

[0033] It should also be noted that both the first transmission wheel 33 and the second transmission wheel 35 are connected to a first rotating block 36.

[0034] Please see Figure 5 The first drive wheel 33 and the second drive wheel 35 are both connected to the first rotating block 36. When the two wheels rotate synchronously, they drive the first rotating block 36 and the rotating shaft 37 and the second rotating block 38 connected to each other to rotate, so that the two sets of turning plates 39 are stirred in the hopper 31, improving the uniformity of the material turning and avoiding local agglomeration and accumulation.

[0035] One end of the telescopic spring 314 is connected to the inside of the hopper 31, and the other end of the telescopic spring 314 is connected to the moving plate 312.

[0036] Please see Figure 5 The telescopic spring 314 is connected at both ends to the inner wall of the hopper 31 and the moving plate 312 respectively. When the vibrating motor 310 drives the vibrating rod 311 to vibrate, the telescopic spring 314 transmits the vibration force to the moving plate 312 and the vibrating plate 313, making the vibration more stable and enhancing the anti-blocking effect.

[0037] It should also be noted that a third servo motor 315 is installed on the top side of the hopper 31 near the top of the vibrating motor 310. The output end of the third servo motor 315 is connected to a stirring paddle 316, which is rotatably connected inside the hopper 31.

[0038] Please see Figure 1 , 4 After the third servo motor 315 starts, its output end drives the stirring paddle 316 to rotate in the hopper 31, pre-stirring the raw materials in the middle of the hopper 31, breaking up any possible lumps, and working in conjunction with the tipping plate 39 and the vibrating plate 313 to form a multi-level material processing, further improving the uniformity of feeding.

[0039] Please see Figures 1 to 5 When the PVC profile extrusion device is working, PVC raw materials are first loaded into hopper 31. The third servo motor 315 is started, and its output end drives the stirring paddle 316 to rotate, pre-stirring the raw materials in the middle of hopper 31 and breaking up clumps. At the same time, the second servo motor 32 is started, and its output end drives the first transmission wheel 33 to rotate. The second transmission wheel 35 rotates synchronously through the belt 34. The two wheels drive the connected first rotating block 36, rotating shaft 37 and second rotating block 38 to rotate respectively. The two sets of tipping plates 39 on the rotating shaft 37 work together to stir the raw materials in hopper 31, improving the uniformity of the raw materials. The vibration motor 310 at the bottom operates, driving the vibration rod 311 to vibrate. The telescopic spring 314 transmits the vibration force to the moving plate 312 and the vibration plate 313, causing them to vibrate at high frequency, avoiding material blockage at the material inlet and ensuring that the material enters the barrel 21 stably. The heating plate 26 inside the mounting bracket 25 on the outside of the barrel 21 is attached to the outer wall and heats the material to the plasticizing temperature through heat conduction. Then, the first servo motor 22 starts, driving the screw 23 to rotate inside the barrel 21, extruding and plasticizing the material. The molten and plasticized material is extruded through the extrusion die 24 to form a PVC profile of a specific shape.
