[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 As shown, the utility model discloses an automatic feeding device for a film blowing machine, comprising: a material receiving box 1 with an opening upward and a feeding barrel 2 fixedly arranged on the right side of the material receiving box 1, the lower part of the inner wall on the right side of the material receiving box 1 is connected to the lower part of the inner wall on the left side of the feeding barrel 2, the upper part of the inner wall of the material receiving box 1 is symmetrically and rotatably provided with two crushing rollers 11, the rear side of the material receiving box 1 is provided with a driving unit 3 for rotating the two crushing rollers 11, the middle part of the inner wall of the material receiving box 1 is driven to be provided with a filter plate 12, the top of the feeding barrel 2 is fixedly provided with a first motor 21, a transmission rod 22 is rotatably provided in the feeding barrel 2, the top of the transmission rod 22 passes through the inner wall of the feeding barrel 2 and is transmission-connected with the execution end of the first motor 21, the outer wall of the transmission rod 22 is wrapped and fixedly provided with an auger 23, the upper part of the outer wall on the right side of the feeding barrel 2 is connected with a feeding pipe 24 with an output end inclined downward, and the output end of the feeding pipe 24 is located directly above the feeding end of the screw extruder.
[0016] Further, such as Figure 2 As shown, the driving unit 3 includes a second motor 31 arranged at the rear side of the material receiving box 1 and two left and right gears 32 symmetrically arranged on the rear side wall of the material receiving box 1, the two gears 32 are meshed with each other, and the gears 32 are connected to the crushing roller 11 through a connecting shaft 33 that penetrates the material receiving box 1, and the rear side of one of the gears 32 is connected to the first transmission wheel 34, and the execution end of the second motor 31 is provided with a second transmission wheel 35, and the second transmission wheel 35 is connected to the first transmission wheel 34 through a transmission belt 36.
[0017] Based on the above structure, Figure 1-2 As shown, when in use, the worker pours the raw material into the open end of the material receiving box 1 and passes it between the two crushing rollers 11. The first motor 21 drives the second transmission wheel 35 to rotate. The second transmission wheel 35 drives the first transmission wheel 34 to rotate through the transmission belt 36 to drive the gear 32 and the crushing roller 11 of the same connecting shaft to rotate. Since the two gears 32 are meshed with each other, the two gears 32 show mirror motion during the rotation process. At the same time, the two crushing rollers 11 rotate toward opposite sides, so that the raw material is evenly crushed. When the crushed raw material passes through the filter plate 12, the filter plate 12 filters out the raw material with larger particles, and the raw material that meets the requirements falls into the bottom end of the inner wall of the material receiving box 1 and enters the bottom end of the inner wall of the feeding barrel 2 connected thereto. At this time, the second motor 21 drives the transmission shaft 22 to drive the auger 23 to rotate, thereby transporting the raw material at the bottom end of the inner wall of the feeding barrel 2 to the top end of the inner wall of the feeding barrel 2, and the raw material is transported to the feed end of the screw extruder by the connected feeding pipe 24.
[0018] Further, such as Figure 1 and 3As shown, in order to facilitate the timely discharge of the filtered raw materials with larger particles to the material receiving box to avoid accumulation and blockage on the filter plate, and at the same time, in order to facilitate the cleaning of the filter plate, the filter plate 12 is arranged downwardly inclined from right to left, and an extension plate 121 is integrally arranged on the right side of the filter plate 12. A discharge port 13 for the extension plate 121 to extend to the outside of the material receiving box 1 is arranged in the middle of the left outer wall of the material receiving box 1, and two slideways 14 for the front and rear ends of the filter plate 12 to be inserted are symmetrically arranged on the front and rear inner walls of the material receiving box 1 at the bottom end of the inner wall of the discharge port 13. When the filter plate 12 filters out the raw materials with larger particles, due to the inclined setting of the filter plate 12, the larger particles of the raw materials will roll along the inclined direction of the filter plate 12 toward the discharge port 13, and finally be discharged from the discharge port 13. When the filter plate 12 needs to be cleaned, the worker grabs the extension plate 121 and pulls it to the left, so as to pull out the extension plate 121 together with the filter plate 12, and then cleans it. After the cleaning is completed, the filter plate 12 is reinserted between the two slideways 14.
[0019] Further, such as Figure 1 and 4 As shown, in order to prevent the filter plate from sliding out of the material receiving box by itself due to the tilted setting of the filter plate, a limiting mechanism 4 is also included in the discharge port 13, and a groove 131 is provided at the top of the inner wall of the discharge port 13. The limiting mechanism 4 includes a limiting column 41 with a top inserted into the groove 131 and a U-shaped bracket 45 for the limiting column 41 to pass through. A limiting ring 42 is fixedly provided in the middle of the outer wall of the limiting column 41, and a paddle 43 is fixedly provided on the outer wall of the limiting ring 42 away from the crushing roller 11. A pressure spring 44 is sleeved on the outer wall of the limiting column 41, and the top and bottom ends of the pressure spring 44 are respectively abutted against the top of the inner wall of the discharge port 13 and the top of the limiting ring 42. The U-shaped bracket 45 is arranged at the bottom end of the limiting ring 42, and the open end of the U-shaped bracket 45 is fixedly connected to the rear inner wall of the discharge port 13. The top end of the extension plate 121 located in the discharge port 13 is provided with a limiting opening 122 for the bottom end of the limiting column 41 to be inserted;
[0020] When the filter plate 12 needs to be cleaned, the staff member pushes the paddle 43 upward with one hand, so that the paddle 43 drives the limiting column 41 to move upward through the limiting ring 42, and the limiting column 41 shrinks into the groove 131, and the limiting ring 42 applies pressure to the compression spring 44, the compression spring 44 shrinks, and the limiting column 41 continues to move upward until the bottom end of the limiting column 41 is separated from the limiting opening 122, at which time the limiting column 41 releases the limit of the extension plate 121, and the extension plate 121 is pulled out together with the filter plate 12 for cleaning, and at this time, the upward push of the paddle 43 is released, the compression spring 44 rebounds, and applies a downward force to the limiting column 41 through the limiting ring 42, and the limiting column 41 moves downward until the bottom end of the limiting ring 42 abuts against the top end of the U-shaped bracket 45;
[0021] After the filter plate 12 is cleaned, the limiting column 41 is driven to move upward again through the paddle 43 and the limiting ring 42, so that the bottom end of the limiting column 41 is higher than the top of the inner wall of the slide 14, and the filter plate 12 is reinserted between the two slides 14, the upward push of the paddle 43 is released, the compression spring 44 rebounds, the limiting column 41 moves downward, and the bottom end of the limiting column 41 is reinserted into the limiting opening 122, thereby re-limiting and fixing the extension plate 121 and the filter plate 12.
[0022] Further, such as Figure 1 and 3 As shown, in order to facilitate the movement of the filtered raw materials into the feeding tube, the bottom end of the material receiving box 1 is tilted downward from left to right.
[0023] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
