Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic pallet production technology, specifically to a feeding device for plastic pallet production. Background Technology
[0002] With the booming development of the logistics industry, the market demand for plastic pallets, as an important tool for cargo storage and transportation, continues to grow. To meet the needs of large-scale production, efficient, stable, and precise feeding devices have become crucial for plastic pallet production. In modern industrial production, the production efficiency and quality of plastic pallets largely depend on the rationality and reliability of the feeding process.
[0003] Due to their small size and light weight, plastic granules are prone to slipping when transported by ordinary conveyor belts because the friction between them and the belt is too low, severely impacting conveying efficiency. Even with partitioned conveyor belts, the situation remains largely unchanged. Plastic granules still easily slip from both sides to the ground, wasting raw materials and affecting the cleanliness of the working environment. Furthermore, during storage, plastic granules are prone to agglomeration due to static electricity, humidity changes, or the inherent characteristics of the granules themselves. Some plastic granules carry static electricity, causing them to adhere together upon contact, forming large agglomerates. When these agglomerates enter the feeding device, they can easily clog the feed inlet or conveying pipes. Utility Model Content

[0025] 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.
[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] Reference Figures 1-4A feeding device for producing plastic pallets includes a base plate 1 and a mixing tank 2. A tray 25 is fixedly connected inside the mixing tank 2, and multiple discharge grooves are provided on the tray 25. The tray 25 facilitates the placement of bags containing plastic granules for discharging. A conical shroud 3 is fixedly connected to the bottom of the mixing tank 2, and a working pipe 4 is connected to the bottom of the conical shroud 3. The bottom of the mixing tank 2 is fixedly connected to the base plate 1 via multiple support legs 5. A cover plate 6 is fixedly connected to the top of the mixing tank 2, and a first motor 7 is mounted on the cover plate 6. The output end of the first motor 7 is connected to a first rotating rod 8, and multiple stirring rods 9 are fixedly connected to the first rotating rod 8. The first motor 7 drives the multiple stirring rods 9 to rotate, thus stirring the plastic granules and removing any clumps. The granules are broken up. A fixed plate 11 is fixedly connected to the transmission pipe 10. The fixed plate 11 is fixedly connected to the base plate 1. The transmission pipe 10 is connected to the discharge pipe 12 and the feed pipe 13. The feed pipe 13 is connected to the working pipe 4. A second motor 14 is installed on the transmission pipe 10. The output end of the second motor 14 is connected to the first sprocket 15. A rotating hole is opened on the transmission pipe 10. A second rotating rod 16 is rotatably connected in the rotating hole. The second rotating rod 16 is connected to the second sprocket 17. The second sprocket 17 and the first sprocket 15 are connected by a chain 18. A first spiral blade 19 is fixedly connected to the second rotating rod 16. The second motor 14 drives the first spiral blade 19 to rotate through the cooperation of the first sprocket 15, the second sprocket 17 and the chain 18 to transport the plastic granules.
[0028] It should also be noted that multiple conductive pins 21 are fixedly connected to the conductive ring 20, and the conductive pins 21 penetrate the mixing tank 2. Multiple copper pipes 22 are fixedly connected to the two conductive rings 20. The bottom end of the copper pipe 22 is connected to a telescopic wire 23, and the bottom end of the telescopic wire 23 is connected to a grounding rod 24. Through the cooperation of the conductive pins 21, conductive rings 20, copper pipes 22, wires and grounding rod 24, the static electricity generated by the plastic particles inside the mixing tank 2 is discharged to prevent the plastic particles from adsorbing together when they come into contact with each other and forming large agglomerates.
[0029] It should be further explained that a second spiral blade 26 is fixedly connected to the first rotating rod 8. The second spiral blade 26 is located inside the working tube 4. The rotation of the second spiral blade 26 discharges the plastic particles into the transmission tube 10, while preventing multiple plastic particles from being blocked due to compression. A filter screen 27 is fixedly connected inside the mixing tank 2. The filter screen 27 intercepts the clumps of plastic particles. Multiple scraper plates 28 are fixedly connected to the first rotating rod 8. The scraper plates 28 move the clumps of plastic particles to prevent a large number of clumps of plastic particles from clogging the filter screen 27.
[0030] In summary, the working principle and process of the feeding device for plastic pallet production are as follows: When in use, the bag containing plastic granules is first placed on the pallet 25 for feeding. Then, the first motor 7 is turned on, which drives multiple stirring rods 9 to rotate through the first rotating rod 8 to stir the plastic granules, thereby breaking up any clumps. The first spiral blade 19 then transports the plastic granules into the transmission pipe 10. The second motor 14, through the cooperation of the first sprocket 15, the second sprocket 17, and the chain 18, drives the first spiral blade 19 to rotate, thereby transporting the plastic granules.
