Description

[0002] Polyvinyl chloride, or PVC for short, is one of the world's most produced plastics. It is known for its low cost and wide range of applications. PVC resin is usually a white or light yellow powder, but it is not suitable for direct use and generally requires modification. PVC is an amorphous white powder with few branches, making it less stable to light and heat. In manufacturing foamed PVC protective materials, the raw material ratio and processing conditions are crucial. By precisely controlling the raw material ratio and using efficient complete production equipment, it is possible to ensure that the produced foamed PVC protective materials have good physical properties and chemical stability. Furthermore, to ensure product quality, parameters such as temperature, humidity, and time during the production process also need to be strictly controlled. Therefore, the raw materials must be kept free of moisture, and rapid cooling is required during high-speed stirring to prevent damage to product performance due to excessively high temperatures.

[0003] Existing high-efficiency complete production equipment for the production of foamed PVC protective materials includes a feeding section, a mixing section, and a filtering section.

Detailed Implementation

[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 Figure 1 This embodiment describes a high-efficiency complete set of production equipment for producing foamed PVC protective materials, including a support platform 1. A stirring extrusion box 2 is fixed on the right side of the upper surface of the support platform 1. A high-speed motor 3 is fixed on the left side of the stirring extrusion box 2 via a mounting bracket. A stirring conveyor wheel 4 is rotatably connected to the left side wall of the inner cavity of the stirring extrusion box 2 via a sealed bearing. The left side of the stirring conveyor wheel 4 rotatably passes through the stirring extrusion box 2 and is fixedly connected to the outside of the output shaft of the high-speed motor 3. A feed pipe 5 is connected to the right side of the upper surface of the stirring extrusion box 2. A filter frame 6 is connected to the top of the feed pipe 5. A conveying mechanism 7 is provided on the left side of the upper surface of the support platform 1. A filter mechanism 8 is provided inside the filter frame 6.

[0026] In this embodiment, an extrusion pipe 9 is connected to the right side of the stirring extrusion box 2, and a spiral cooling pipe 10 is embedded and fixed on the inner peripheral wall of the stirring extrusion box 2. A water inlet pipe is fixed on the left side of the upper surface of the stirring extrusion box 2, and the bottom end of the water inlet pipe passes through the stirring extrusion box 2 and is connected to the water inlet end of the spiral cooling pipe 10. A water outlet pipe is fixed on the right side of the upper surface of the stirring extrusion box 2, and the bottom end of the water outlet pipe passes through the stirring extrusion box 2 and is connected to the water outlet end of the spiral cooling pipe 10. An external water source can be connected through the top end of the water inlet pipe. Water from the external water source enters the spiral cooling pipe 10 to cool the material inside the stirring extrusion box 2. The cooled water is discharged through the water outlet pipe.

[0027] It should be noted that the rotating stirring and conveying wheel 4 can stir the material and convey it to the right, and the spiral cooling pipe 10 can cool the material.

[0028] Please see Figures 2 to 3In this embodiment, the conveying mechanism 7 includes four first spring telescopic rods 701 fixed on the upper surface of the support platform 1. A fixing plate 702 is fixed on the upper surface of the four first spring telescopic rods 701. A conveyor belt 703 is fixed on the upper surface of the fixing plate 702 through a support frame. Baffles 704 are fixed on both the front and rear sides of the upper surface of the conveyor belt 703. A stop block 705 is fixed on the left side of the front and rear side baffles 704. Several baffle strips 706 are fixed on the outer side of the conveyor belt 703. A first vibration structure 707 is fixed on both the left and right sides of the upper surface of the fixing plate 702.

[0029] Specifically, the conveying mechanism 7 also includes two support plates 708 fixed on the left side of the upper surface of the support platform 1. Each of the left and right support plates 708 has a limiting groove 709 on its opposite side. A slider 710 is slidably connected inside the limiting groove 709. The opposite sides of the sliders 710 on both sides are fixedly connected to the left and right sides of the fixed plate 702. The first spring telescopic rod 701 includes a first slide rod. A second slide rod is slidably connected inside the first slide rod. A first spring is movably fitted on the outside of the first slide rod.

[0030] Specifically, the first vibration structure 707 includes a first mounting frame, inside which a first vibration motor is fixed. The left and right support plates 708 are slidably connected to the left and right sides of the fixed plate 702 on opposite sides. PVC granules and other additives are mixed in a certain proportion to form a premix, which is then poured onto the upper surface of the conveyor belt 703. The premix is ​​prevented from falling off the upper surface of the conveyor belt 703 by the stop block 705 and two baffles 704. Then, the conveyor belt 703 is turned on and the premix is ​​conveyed to the right by at least two baffles 706, and then falls into the filter frame 6 during the conveying process.

[0031] It should be noted that the first vibration structure 707 on the left and right sides can be opened. Through the interaction of the four first spring telescopic rods 701, the sliders 710 on the left and right sides, and the limiting grooves 709 on the left and right sides, the conveyor belt 703 can vibrate up and down. When the conveyor belt 703 vibrates up and down, the premixed material adhering to the conveyor belt 703 can be vibrated and dropped into the filter frame 6, thereby improving the feeding efficiency.

[0032] Please see Figure 4 In this embodiment, the filtering mechanism 8 includes a guide cylinder 801 fixed inside the filter frame 6. A second spring telescopic rod 802 is fixed on both the left and right sides of the upper surface of the guide cylinder 801. A filter cylinder 803 is fixed on the upper surface of the second spring telescopic rods 802 on both the left and right sides. A filter screen 804 is fixed inside the filter cylinder 803. The filter cylinder 803 is slidably connected inside the filter frame 6. A second vibration structure 805 is fixed on both the left and right sides of the lower surface of the filter cylinder 803.

[0033] Specifically, the second spring telescopic rod 802 includes a third slide rod, a fourth slide rod is slidably connected inside the third slide rod, and a second spring is movably fitted on the outside of the third slide rod. The second vibration structure 805 includes a second mounting frame, a second vibration motor is fixed inside the second mounting frame, and the filter cylinder 803 moves linearly up and down inside the filter frame 6.

[0034] Specifically, the material extruded through the extrusion tube 9 can be filled into a 200L iron drum.

[0035] It should be noted that after the premixed material falls into the filter frame 6, the second vibration structure 805 on both sides is activated. The second spring telescopic rods 802 on both sides drive the filter cylinder 803 and filter screen 804 to vibrate up and down, reducing the risk of clogging. Then, the premixed material enters the mixing extrusion box 2 through the feed pipe 5. The high-speed motor 3 then provides power, driving the mixing conveyor wheel 4 to rotate at high speed, ensuring uniform mixing of the premixed material. Simultaneously, the special design of the mixing conveyor wheel 4 allows the premixed material to be conveyed to the right. Under the action of the mixing conveyor wheel 4, the premixed material not only achieves rapid mixing but also moves along the conveying direction, preparing for subsequent cooling. In preparation for extrusion, the spiral cooling pipe 10 is designed to increase the contact area and contact time between the cooling water and the premix, thereby more effectively removing heat from the premix. The cooling water flows in the spiral cooling pipe 10, carrying away the heat of the premix and lowering its temperature. Cooling can prevent the premix from undergoing adverse reactions (such as decomposition or deterioration) due to excessive temperature during subsequent extrusion. It also helps to improve the quality and efficiency of extrusion. After cooling, the premix enters the extrusion pipe 9 and is extruded. The extruded material can be directly filled into 200L iron drums. These large-capacity iron drums are suitable for large-scale material storage and transportation, facilitating subsequent use and processing.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, PVC granules and other additives are mixed in a certain proportion to form a premix, which is then poured onto the upper surface of the conveyor belt 703. The baffle 705 and two baffles 704 prevent the premix from falling off the upper surface of the conveyor belt 703. Then, the conveyor belt 703 is turned on, and the premix is ​​conveyed to the right by at least two baffles 706, falling into the filter frame 6. During conveying, the first vibration structures 707 on both sides can be activated. Through the interaction of the four first spring telescopic rods 701, the sliders 710 on both sides, and the limiting grooves 709 on both sides, the conveyor belt 703 vibrates up and down. When 703 vibrates up and down, it can vibrate and drop the premixed material adhering to the conveyor belt 703 into the filter frame 6, improving the feeding efficiency. After the premixed material falls into the filter frame 6, the second vibration structure 805 on the left and right sides is activated. The second spring telescopic rods 802 on the left and right sides can drive the filter cylinder 803 and filter screen 804 to vibrate up and down, reducing the possibility of clogging. Then, the premixed material enters the mixing and extrusion box 2 through the feed pipe 5. Under the drive of the high-speed motor 3, the mixing and conveying wheel 4 drives the premixed material to be mixed at high speed and conveyed to the right. At the same time, the water in the spiral cooling pipe 10 cools the premixed material. Then, it is extruded through the extrusion pipe 9.
