DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0016] The utility model provides a single-station material spreading device for producing molded pallets, comprising a processing platform 1, a mold 2 is arranged on the processing platform 1, a material spreading mechanism for feeding material into the mold 2 is arranged at one end of the processing platform 1, a pallet transfer mechanism is arranged at the other end of the processing platform 1, a power component for driving the material spreading mechanism to approach or move away from the mold 2 is arranged on the material spreading mechanism, and a scraper 3, a material pressing component and a release agent spraying mechanism are also arranged on the material spreading mechanism.

[0017] like Figure 1 and 2 As shown, the function of the material pressing component is to preliminarily compact the sticky material during the material laying process so that the laid material will not move at will. The function of the scraper 3 is to flatten the uneven parts of the pressed material. The mold 2 is embedded in the processing platform 1. A molding machine is provided on the top of the processing platform 1 to mold the material in the mold 2. A mechanism for lifting the formed tray is provided at the bottom of the mold 2. The power component drives the material laying mechanism to move toward the mold 2. The demoulding agent spraying mechanism evenly sprays the demoulding agent into the mold 2 and the bottom of the mold on the molding machine. Since the material contains adhesive, the function of spraying the demoulding agent is to prevent the material from sticking to the mold 2 and the mold on the molding machine, which is convenient for the later demoulding work. During the operation, when the material spreading mechanism is located directly above the mold 2, as the power component drives the material spreading mechanism to move, the material spreading mechanism will evenly pour a certain amount of mixed material into the mold 2 sprayed with the release agent, and the pressing component will compact it, and then use the scraper 3 to scrape the uneven parts of the compacted material to ensure that the material is evenly spread in the mold 2; then start the molding machine on one side of the processing platform 1 to extrude the material in the mold 2, and finally use the jacking mechanism to push the formed tray out of the mold 2, and then use the tray transfer mechanism to transfer the tray out of the mold 2; in the material spreading process, mechanized work is adopted, and there is no need for manual spraying of release agent, material spreading, spreading and other operations, which greatly reduces the workload, improves work efficiency and ensures product quality.

[0018] The material spreading mechanism includes a material spreading frame 4, an upper hopper 5 and a material dispensing roller 6. The upper hopper 5 is installed on the top of the material spreading frame 4 and is connected to the material spreading frame 4. The material dispensing roller 6 is rotatably arranged in the material spreading frame 4. A motor 7 for driving the material dispensing roller to rotate is provided on one side of the material spreading frame 4.

[0019] like Figure 1As shown, the mixed material is put into the upper hopper 5, and the motor 7 is in the unstarted state. Under the action of the material-discharging roller 6, the end of the fin on the material-discharging roller 6 contacts the inner wall of the material-laying frame 4, so that the discharge port at the bottom of the material-laying frame 4 is in a closed state. Only when the motor 7 is started to drive the material-discharging roller 6 to rotate, the fin on the material-discharging roller 6 rotates to a position away from the inner wall of the material-laying frame 4, and the discharge port of the material-laying frame 4 is in an open state. The rotating material-discharging roller 6 evenly drops the material in the upper hopper 5 into the mold 2 at the bottom of the material-laying frame 4.

[0020] The power assembly includes a slide rail 8 and a hydraulic cylinder 9. The slide rail 8 is arranged on both sides of the top of the processing platform 1, that is, located on both sides of the mold 2. A slider 10 is slidably installed on the slide rail 8. The slider 10 is connected to the material laying frame 4 through a connecting plate. The hydraulic cylinder 9 is arranged on the processing platform 1, and the piston rod of the hydraulic cylinder 9 is connected to the material laying frame 4.

[0021] like Figure 1 As shown, the material laying frame 4 slides on the top of the processing platform 1 under the action of the slide rail 8 and the slider 10, and the material laying frame 4 is controlled to move back and forth above the mold 2 by controlling the hydraulic rod 9.

[0022] A scraping cavity 11 is formed between the scraper 3 and the outer wall of the material laying frame 4. The scraping cavity 11 is connected to the material laying frame 4. The pressing assembly includes a pressing roller 12, which is rotatably arranged in the scraping cavity 11. A motor 13 for driving the pressing roller 12 to rotate is arranged outside the material laying frame 4. A scraping plate 18 is arranged on the outer wall of the material laying frame 4 on the side close to the pressing roller 12. The scraping plate 18 is located above the roller surface of the pressing roller 12. The bottom of the scraping plate 18 is close to the roller surface of the pressing roller 12 and does not affect the rotation of the pressing roller 12. The scraping plate 18 is used to scrape the material on the pressing roller 12.

[0023] like Figure 1 As shown, the motor 2 13 drives the press roller 12 to rotate to compact the material spread in the mold 2. The scraper plate 18 can scrape off the material that may adhere to the roller surface of the press roller 12 to facilitate the subsequent pressing work. The scraped material falls onto the mold 2 and continues to be flattened by the press roller 12.

[0025] like Figure 2 As shown, the release agent storage tank 14 , the nozzle, the bracket 15 and the nozzle 17 will slide along the slide rail 8 along with the material laying frame 4 , and the infusion pump will transport the release agent in the release agent storage tank 14 to the nozzle 16 , and the release agent will be sprayed into the mold 2 by the nozzle 17 .

[0026] Principle of use: Place a certain amount of evenly stirred sawdust, adhesive and other materials in the upper hopper 5, and the hydraulic cylinder 9 drives the material laying frame 4 to move along the slide rail 8 toward the mold 2. At the same time, the infusion pump is started to deliver the release agent to the nozzle 16, and then the nozzle 17 evenly sprays it into the mold 2 and the bottom surface of the mold of the molding machine. When the discharge port at the bottom of the material laying frame 4 is at the top of the mold 2, start the motor 7 to drive the material roller 6 to rotate and evenly drop the material into the mold 2. After spraying and unloading are completed, turn off the infusion pump. and motor 1 7. At this time, the material spreading frame 4 is located on the other side of the mold 2. The hydraulic cylinder 9 is retracted to drive the material spreading frame 4 to move in the opposite direction along the slide rail 8, and the motor 2 13 is started. The motor 2 13 drives the pressing roller 12 to rotate to compact the material falling into the mold 2. At the same time, the scraper 3 flattens the uneven parts of the compacted material, and then the molding machine is used to extrude the material in the mold 2 after scraping. The formed tray is pushed out of the mold 2 by the lifting mechanism, and finally the tray is transferred out of the mold 2 by the tray transfer mechanism.
