[0012] (2) The utility model provides a shielding component. By closing the end cover when the device is not in use, the airbag is squeezed and the slider pushes the baffle plate, so that the baffle plate blocks the waste residue attached to the inner wall of the hopper when not in use, thereby preventing the waste residue from falling and blocking the through hole between the hopper and the machine body.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-3, an anti-clogging injection molding machine includes a body 1, a feed hopper 2 is arranged on the top of the body 1, an anti-clogging mechanism 3 is arranged inside the feed hopper 2, a shielding component 4 is arranged inside the feed hopper 2, the anti-clogging mechanism 3 includes a mounting plate 31, the mounting plate 31 is slidably connected to the body 1, an elliptical block 32 is slidably connected to the top of the body 1, a motor 33 is fixedly connected to the mounting plate 31, the distance between the longer side of the elliptical block 32 and the midpoint is consistent with the distance between the output shaft of the motor 33 and the lower surface of the mounting plate 31, and the consistency of the distance between the output shaft of the motor 33 and the mounting plate 31 and the radius of the longer axis of the elliptical block 32 is ensured that the elliptical block 32 cannot always contact the mounting plate 31 during the rotation process, so as to ensure that the elliptical block 32 can rotate normally without being obstructed, the output shaft of the motor 33 is fixedly connected to the elliptical block 32, the output shaft of the motor 33 is fixedly connected to a rotating rod 34, the rotating rod 34 is fixedly connected to a bevel gear 35, the mounting plate 3 The rotating bar 36 is rotatably connected to the rotating bar 36, and a bevel gear 2 37 is fixedly connected to the rotating bar 36. A paddle 38 is fixedly connected to the rotating bar 36. The rotating rod 34 is slidably connected to a shield plate 39. The width of the shield plate 39 is greater than the width of the slot opened on the side wall of the feed hopper 2 for the rotating rod 34 to pass through, and the surface of the shield plate 39 is smooth. By setting the width of the shield plate 39, it is ensured that the shield plate 39 can completely cover the slot, thereby ensuring that no material will flow out of the feed hopper 2 during use. The shield plate 39 is slidably connected to the inner wall of the feed hopper 2, and the elliptical block 32 is driven to rotate by the output shaft of the motor 33, so that the mounting plate 31 drives the rotating bar 36 and the paddle 38 to move up and down, and the output shaft of the motor 33 and the bevel gear 1 35 and the bevel gear 2 37 work together to rotate the rotating bar 36 and the paddle 38, so that the paddle 38 moves up and down and rotates at the same time, thereby ensuring that the material can fall normally and is not easily blocked.

[0020] When in use, the staff first pours the material into the hopper 2, and then starts the power supply of the equipment to start the motor 33. At this time, the output shaft of the motor 33 rotates, thereby driving the elliptical block 32 to rotate. When the elliptical block 32 rotates until the major axis is in a vertical position, the distance between the elliptical block 32 and the upper surface of the body 1 increases, so that the elliptical block 32 drives the motor 33 and the mounting plate 31 to move upward. At this time, the mounting plate 31 drives the rotating rod 34 and the rotating bar 36 to move upward. At the same time, the output shaft of the motor 33 drives the bevel gear 1 35 to rotate during the rotation process, so that the bevel gear 1 35 drives the bevel gear 2 37 to rotate. When the paddle 38 is driven to rotate, the rotating bar 36 is driven to rotate through the bevel gear 37, so that the rotating bar 36 drives the paddle 38 to rotate, so that the paddle 38 can move up and down and rotate at the same time under the drive of the rotating bar 36, so that part of the material under the feed hopper 2 is moved upward under the drive of the paddle 38, so that the material under the feed hopper 2 is reduced, which is convenient for the material to fall, and at the same time, the paddle 38 pushes the material to move downward when it moves downward, which is convenient for the material to fall, and the paddle 38 can scrape off the material adhering to the inner wall of the feed hopper 2 during the rotation process, so as to prevent adhesion and facilitate the material to fall.

[0021] See also Figure 1-4 On the basis of the first embodiment, the shielding component 4 includes an air pressure bin 41, part of which is opened in the inner wall of the feed hopper 2, and the other part of the air pressure bin 41 is opened in the inner wall of the body 1, and the part of the air pressure bin 41 in the feed hopper 2 is connected with the part in the inner wall of the body 1. By setting the position of the air pressure bin 41, it is ensured that when the air bag 42 above the air pressure bin 41 is squeezed, the baffle 45 below the air pressure bin 41 can slide to achieve the expected effect. The air pressure bin 41 is connected to the air bag 42, and the air bag 42 is arranged on the top of the feed hopper 2. The feed hopper 2 is rotatably connected with an end cover 43, and a card block is fixedly connected to the outer wall of the feed hopper 2. The end cover 43 is rotatably connected. A connecting strip whose shape and size match the card block is connected. The card block and the connecting strip are set to ensure that when the equipment is not in use, the end cover 43 can keep the hopper 2 closed. A slider 44 is slidably connected to the inner wall of the air pressure chamber 41. The slider 44 is fixedly connected to the baffle 45. The baffle 45 is slidably connected to the inner wall of the body 1. The slider 44 is elastically connected to the inner wall of the air pressure chamber 41 through a tension spring 46. Through the shielding component 4, the end cover 43 is closed when the equipment is not in use, so that the airbag 42 is squeezed and then the slider 44 pushes the baffle 45, so that the baffle 45 blocks it, thereby preventing the waste residue attached to the inner wall of the hopper 2 from falling when not in use and blocking the through hole between the hopper 2 and the body 1.

[0022] During use, on the basis of Example 1, when the equipment is not needed, the end cover 43 is closed so that the end cover 43 squeezes the airbag 42, so that the gas inside the airbag 42 enters the interior of the air pressure chamber 41, and the air pressure inside the air pressure chamber 41 increases, so that the slider 44 moves under the action of the air pressure and pushes the baffle 45, so that the baffle 45 moves to block the through hole between the feed hopper 2 and the body 1, thereby blocking the through hole and preventing the waste residue attached to the inner wall of the feed hopper 2 from falling and blocking the through hole when the equipment is not in use.
