Description

Technical Field

[0001] This utility model belongs to the field of polyester powder coating production technology, and in particular relates to an extruder for processing polyester powder coatings. Background Technology

[0002] Polyester powder coatings are 100% solids, solvent-free powder coatings made with polyester resin as the core film-forming substance, supplemented with curing agents, pigments, fillers, and additives (such as leveling agents, defoamers, and anti-yellowing agents), through processes such as mixing, melt extrusion, and crushing and sieving. They belong to an important category of thermosetting or thermoplastic powder coatings (among which thermosetting polyester powder coatings are the most widely used). Based on polyester resin (distinguishing it from other types of powder coatings such as epoxy, acrylic, and polyurethane), the structure of the polyester resin (such as saturated / unsaturated, carboxyl / hydroxyl type) determines the core properties of the coating, such as adhesion, weather resistance, and hardness.

[0003] When polyester powder coatings are extruded, the extruded product falls onto the conveyor belt. As production continues, debris and impurities accumulate on the conveyor belt. If not cleaned in time, the extruded product will be covered with debris and impurities, affecting the final quality of the product. Based on this, an extruder for processing polyester powder coatings is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an extruder for processing polyester powder coatings, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an extruder for processing polyester powder coatings, comprising: a base plate, a working device fixedly mounted on the top of the base plate, a hopper fixedly mounted on one side of the working device, an extrusion device fixedly mounted on the top of the base plate and connected to the working device, a driving device provided on the side of the working device away from the extrusion device and connected to the working device, and a receiving mechanism provided on the end of the extrusion device away from the working device; the receiving mechanism includes a support frame, a conveyor belt fixedly mounted on the top of the support frame, a top cover fixedly mounted on the top of the conveyor belt, an installation frame fixedly mounted on the top of the top cover, fans symmetrically fixedly mounted on the top of the installation frames, and dustproof nets fixedly mounted on the top of the installation frames.

[0006] Furthermore, the receiving mechanism also includes a mounting frame fixedly installed on the top of the support frame. The bottom end of the mounting frame is rotatably connected to a mounting rod. A mounting roller is fixedly installed on the mounting rod. The outer ring of the mounting roller is provided with a plurality of mounting grooves at equal intervals. A cleaning plate is installed in each of the mounting grooves on the outer ring of the mounting roller. Both ends of the mounting roller are slidably sleeved with retaining rings, and the retaining rings are pressed and engaged with the ends of the cleaning plates.

[0007] When producing polyester powder coatings, the workers first place the material to be processed in the hopper. Then, the drive unit, in conjunction with the working unit, drives the extrusion unit to extrude the material. The extruded product enters the receiving mechanism and falls onto the conveyor belt. Through the continuous conveying of the conveyor belt, the product is evenly spread on the surface of the belt. At this time, the fan will evenly cool the product passing below. As the conveyor belt continues to operate, the surface of the conveyor belt will pass through the cleaning plate. The cleaning plate cleans the surface of the conveyor belt, keeping it clean at all times. This prevents debris or impurities from adhering to the surface of the freshly extruded product, which would affect the final quality of the product and further improve the quality of the equipment during production.

[0008] To improve the cleaning effect of the cleaning plate, the staff can pull the retaining rings towards both ends of the mounting rod. At this time, the cleaning plate can be disassembled without the restriction of the retaining rings, which facilitates cleaning or maintenance of the cleaning plate, increases the convenience of the device during use, and makes it more convenient for staff to use.

[0009] Furthermore, the inner ring of the retaining ring is provided with a pressing surface for pressing and engaging the two ends of the cleaning plate. Both ends of the cleaning plate are provided with grooves that engage with the retaining ring. The pressing surface of the inner ring of the retaining ring facilitates the pressing and restraint of the ends of the cleaning plate, thereby restricting the cleaning plate and enabling it to clean the surface of the conveyor belt during operation. In addition, the pressing and restraint setting facilitates the quick disassembly of the cleaning plate, further improving the convenience and smoothness of the device during use, while the groove setting allows for the installation of the cleaning plate.

[0010] Furthermore, a number of baffles are fixedly installed at equal intervals on the outer surface of the conveyor belt. The baffles on the surface of the conveyor belt can restrict the products falling onto the surface of the conveyor belt, preventing the products from sliding down the surface of the conveyor belt at will. At the same time, the baffles can separate the products falling onto the surface of the conveyor belt, thereby preventing multiple products from piling up and causing insufficient cooling of the products, which would lead to the products sticking to the surface of the conveyor belt, thus enabling better production.

[0011] Furthermore, drive wheels are installed at both ends of the mounting rod. The outer ring of the drive wheel is provided with several extrusion grooves at equal intervals. The outer ring of the drive wheel is in extrusion fit with the conveyor belt and the baffle. In order to better drive the cleaning plate to clean the surface of the conveyor belt, drive wheels are provided at both ends of the mounting rod. The drive wheels and the surface of the conveyor belt are in mutual extrusion. As the conveyor belt continues to run, it drives the drive wheels to rotate, thereby better driving the cleaning plate to rotate and realize the cleaning work on the surface of the conveyor belt.

[0012] Furthermore, a horizontal plate is fixedly installed on one side of the mounting frame, and a number of nozzles are fixedly installed at equal intervals on one side of the horizontal plate, with the nozzles facing the conveyor belt. In order to improve the cleaning effect of the cleaning plate on the surface of the conveyor belt, a nozzle is provided on one side of the mounting frame, which can continuously spray air onto the cleaning end of the cleaning plate, so as to quickly clean up the cleaned material and prevent impurities from adhering to the surface of the conveyor belt.

[0013] Furthermore, the bottom end of the mounting frame is provided with a 30° slope, which can guide impurities and prevent them from accumulating at the bottom end of the mounting frame.

[0014] This utility model has the following beneficial effects: This invention, through the setting of the receiving mechanism, can quickly separate the extruded products, preventing them from falling onto the surface of the conveyor belt and sliding down randomly. It can also prevent multiple products from piling up and causing insufficient cooling, which would lead to the products sticking to the surface of the conveyor belt, thus improving production.

[0015] This invention uses a cleaning plate to clean the surface of the conveyor belt, ensuring that the conveyor belt remains clean at all times. This prevents debris or impurities from adhering to the surface of the freshly extruded product, thus affecting the final product quality and further improving the quality of the equipment during production. To enhance the cleaning effect of the cleaning plate, the operator can pull the retaining rings towards both ends of the mounting rod. At this point, the cleaning plate can be disassembled without the restriction of the retaining rings, facilitating cleaning or maintenance of the cleaning plate, increasing the convenience of the equipment during use, and making it more convenient for operators to use.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7This utility model relates to an extruder for processing polyester powder coatings, comprising: a base plate 1, a working device 2 fixedly mounted on the top of the base plate 1, a hopper 3 fixedly mounted on one side of the working device 2, an extrusion device 4 fixedly mounted on the top of the base plate 1, and the extrusion device 4 and the working device 2 being connected in a cooperative manner; a driving device 5 is provided on the side of the working device 2 away from the extrusion device 4, and the driving device 5 is installed and cooperates with the working device 2; a receiving mechanism 6 is provided on the end of the extrusion device 4 away from the working device 2; the receiving mechanism 6 includes a support frame 7, a conveyor belt 8 fixedly mounted on the top of the support frame 7, a top cover 9 fixedly mounted on the top of the conveyor belt 8, an installation frame 10 fixedly mounted on the top of the top cover 9, fans 11 symmetrically fixedly mounted on the top of the installation frame 10, and a dustproof net 12 fixedly mounted on the top of the installation frame 10.

[0022] The receiving mechanism 6 also includes a mounting frame 13 fixedly installed on the top of the support frame 7. The bottom end of the mounting frame 13 is rotatably connected to a mounting rod 14. A mounting roller 15 is fixedly installed on the mounting rod 14. The outer ring of the mounting roller 15 is provided with a plurality of mounting grooves at equal intervals.

Both ends of the mounting roller 15 are slidably sleeved with retaining rings 17, and the retaining rings 17 are pressed and engaged with the ends of the cleaning plates 16.

[0023] When polyester powder coatings need to be produced, the workers first place the material to be processed in the hopper 3. Then, the drive unit 5, in conjunction with the working unit 2, drives the extrusion unit 4 to extrude the material. The product extruded by the extrusion unit 4 enters the receiving mechanism 6 and falls onto the conveyor belt 8. Through the continuous conveying of the conveyor belt 8, the product is evenly spread on the surface of the conveyor belt 8. At this time, the fan 11 will evenly cool the product passing below it. As the conveyor belt 8 continues to operate, the surface of the conveyor belt 8 will pass through the cleaning plate 16. The cleaning plate 16 cleans the surface of the conveyor belt 8, keeping the surface of the conveyor belt 8 clean at all times. This prevents debris or impurities from adhering to the surface of the freshly extruded product, which would affect the final quality of the product and further improve the quality of the equipment during production.

[0024] In order to improve the cleaning effect of the cleaning plate 16, the staff can pull the retaining ring 17 towards both ends of the mounting rod 14.

[0025] The inner ring of the retaining ring 17 is provided with a pressing surface for pressing and engaging the two ends of the cleaning plate 16. Both ends of the cleaning plate 16 are provided with grooves that engage with the retaining ring 17. The pressing surface of the inner ring of the retaining ring 17 facilitates the pressing and restricting of the ends of the cleaning plate 16, thereby restricting the cleaning plate 16 and enabling the cleaning plate 16 to clean the surface of the conveyor belt 8 during operation. In addition, the pressing and restricting setting facilitates the quick disassembly of the cleaning plate 16, further improving the convenience and smoothness of the device during use, while the groove setting allows for the installation of the cleaning plate 16.

[0026] A plurality of baffles 21 are fixedly installed at equal intervals on the outer surface of the conveyor belt 8. The baffles 21 on the surface of the conveyor belt 8 can restrict products falling onto the surface of the conveyor belt 8, preventing products from sliding down the surface of the conveyor belt 8 at will. At the same time, the baffles 21 can separate products falling onto the surface of the conveyor belt 8, thereby preventing multiple products from piling up and causing insufficient cooling of the products, which would lead to the products sticking to the surface of the conveyor belt 8, thus enabling better production.

[0027] Both ends of the mounting rod 14 are equipped with drive wheels 18. The outer ring of the drive wheels 18 is provided with several extrusion grooves at equal intervals.

In order to better drive the cleaning plate 16 to clean the surface of the conveyor belt 8, the mounting rod 14 is provided with drive wheels 18 at both ends. The drive wheels 18 are in mutual extrusion with the surface of the conveyor belt 8. As the conveyor belt 8 continues to run, it drives the drive wheels 18 to rotate, thereby better driving the cleaning plate 16 to rotate, so as to achieve the cleaning work on the surface of the conveyor belt 8.
