Common equipment includes dry mixers, plastic granulators, and woven bag shredders. Dry mixers are used to dry and mix the raw materials evenly, removing moisture and ensuring stability in subsequent processing. Raw materials such as polypropylene and polyethylene particles usually contain a certain amount of moisture, which is removed by drying equipment. Common types include hot air dryers, which use circulating hot air to dry the raw materials, preventing moisture from causing defects such as bubbles and cracks in the finished products during processing, thus ensuring product quality.

Detailed Implementation

[0029] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0030] According to one embodiment of the present invention, in conjunction with Figures 1-2 The diagram shows a raw material processing device for producing laminated woven bags, including a drying drum 1 and a conical hopper 2 welded to the bottom of the drying drum 1. The upper opening of the conical hopper 2 is larger than the lower opening. A feed hopper 3 is welded to the bottom of the conical hopper 2. A hot air component 4 is screwed to the side of the conical hopper 2 for conveying hot air into the drying drum 1 to dry the raw materials. A controller 5 is screwed to the side of the drying drum 1. A drive device 6 is welded to the bottom of the feed hopper 3.

[0031] In this embodiment, combined with Figure 3 As shown, the drive device 6 includes a motor 61, one end of which is rotatably connected to a gear 62. The lower end of the gear 62 is vertically meshed with a gear 63, and the upper end of the gear 62 is vertically meshed with a gear 64. The gear 64 is rotatably nested on the central shaft of the gear 63. The gears 63 and 64 rotate in opposite directions. The middle part of the gear 63 is connected to a feeding screw 7 by welding, and the middle part of the gear 64 is connected to a spiral dropping disc 8 by welding. The motor 61 can drive the gear 62 to rotate, thereby causing the gears 63 and 64 to rotate, which in turn drives the feeding screw 7 and the spiral dropping disc 8 to rotate respectively.

[0032] In this embodiment, combined with Figures 4-5 As shown, the feeding screw 7 includes a threaded section 71. The bottom end of the threaded section 71 is located at the internal opening of the feed hopper 3. The bottom end of the threaded section 71 is at the same horizontal line as the bottom end of the feed hopper 3. A smooth section 72 is provided below the threaded section 71. The smooth section 72 is connected to the gear 63 by welding. When raw material is fed into the feed hopper 3, the raw material enters from the inlet and falls onto the threaded section 71 of the feeding screw 7. The smooth section 72 rotates, causing the threaded section 71 to rotate upward, which drives the raw material to be conveyed upward.

[0033] In this embodiment, combined with Figures 4-5As shown, the spiral drop disc 8 includes a rotating disc 81 with a hollow cavity in the middle. The feeding screw 7 rotates through the hollow cavity to convey the raw material upwards. A hollow column 82 is welded to the lower end of the rotating disc 81. The hollow column 82 is located inside the cone hopper 2, and the bottom of the hollow column 82 is on the same plane as the bottom surface of the lower opening of the cone hopper 2. Multiple support columns 83 are welded to the bottom of the hollow column 82. The support columns 83 are installed inside the feed hopper 3, and gaps are left between the support columns 83 to ensure that the raw material enters from the feed hopper 3. The bottom of the support columns 83 is fixedly connected to the upper surface of the gear 64 by welding. The rotation of the gear 64 can drive the spiral drop disc 8 to rotate, which can convey the raw material falling from the top down.

[0034] In this embodiment, combined with Figure 6 As shown, the cone hopper 2 includes a cone-shaped inclined surface 21. A return port 22 is provided on the side of the cone-shaped inclined surface 21 near the feed hopper 3, which is the channel for the continued circulation and drying of raw materials. An outlet 23 is provided on the side of the cone-shaped inclined surface 21 away from the feed hopper 3, which is the channel for the raw materials to be discharged after reaching the drying standard. An air inlet 24 is also provided on the side of the cone-shaped inclined surface 21, which is the channel for transmitting hot air into the drying barrel 1 for drying raw materials. A scraper 25 is installed on the bottom side of the hollow column 82 at the same level as the bottom of the cone hopper 2. When the hollow column 82 rotates, it can drive the scraper 25 to rotate around the bottom edge of the cone hopper 2. The rotation of the scraper 25 can carry the falling raw materials to the return port 22 or the outlet 23. A humidity sensor 26 is installed on the surface of the scraper 25 by screws, which can detect whether the humidity of the falling raw materials has reached the drying standard.

[0035] In this embodiment, combined with Figure 6 As shown, the feed hopper 3 includes a feed inlet trough 31, and a humidity sensor 2 32 is installed on the side wall of the feed inlet trough 31 by screws to detect the humidity of the raw material falling from the return port 22.

[0036] In this embodiment, combined with Figure 7 As shown, the return port 22 includes a return pipe 221, with a solenoid valve 222 installed in the middle of the return pipe 221. The discharge port 23 includes a discharge pipe 231, with a solenoid valve 232 installed in the middle of the discharge pipe 231. The solenoid valves 222 and 232 can be controlled by sensing the electrical signals of the humidity sensors 26 and 32 to open and close the return port 22 and the discharge port 23. When the humidity detected by the humidity sensors 26 and 32 reaches the drying standard at the same time, the solenoid valve 232 opens and the solenoid valve 222 closes, and the dried raw material is output from the discharge port 23. When only one of the humidity sensors 26 and 32 reaches the drying standard, the solenoid valve 232 closes and the solenoid valve 222 opens, and the raw material is output from the return port 22 and re-enters the drying cycle.

[0037] In this embodiment, combined with Figures 1-7 As shown, when drying raw materials, the raw materials are first fed into the feed hopper 3. At this time, the motor 61 and the hot air component 4 are turned on. Driven by the motor 61, the raw materials are conveyed upward to the top by the feeding screw 7. At the highest point, due to centrifugal force, they fall into the spiral drop plate 8. The spiral drop plate 8 rotates and sends the raw materials into the lower cone hopper 2. During this process, the hot air component 4 continuously delivers hot air to dry the raw materials. The raw materials in the cone hopper 2 are scraped by the scraper 25. The humidity sensor 26 on the scraper 25 detects the raw materials. According to the degree of dryness of the raw materials, the solenoid valve 222 and the solenoid valve 232 are opened accordingly, so that the raw materials enter the return port 22 or the discharge port 23.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
