Description

Technical Field

[0001] This application relates to the field of feeding mechanisms, and more specifically, to a feeding mechanism for a granulator. Background Technology

[0002] Granulation is a process of making products into granules. In the granulation process of some plastic materials, the raw materials need to be melted and then extruded and cut into granules using an extrusion device. The granulated products need to be screened and collected by a feeding device.

[0003] Patent document CN217780186U discloses a rapid separation and collection granulation feeding mechanism, comprising a device housing with an open, hollow, square structure. Leveling feet are longitudinally fixed at the four corners of the lower surface of the housing, and three collection boxes are evenly spaced from left to right below the housing. A feeding screen is fixedly installed inside a carrying plate, and a cooling chamber is fixedly installed inside the upper part of the housing. This rapid separation and collection granulation feeding mechanism employs a novel structural design. During use, the rotation of a transverse screw drives a pusher plate to move left and right, leveling the product. The rotation of a push cam and the cooperation of a vibration spring cause the feeding screen to vibrate up and down, increasing the screening speed. Simultaneously, after granulation, the product falls and is rapidly cooled by water inside the cooling chamber, preventing sticking.

[0004] Although the application documents state that the product pellets are rapidly cooled by water inside the cooling chamber after granulation to prevent them from sticking together, a large number of defective products can clog the screen and damage the machine.

[0005] Therefore, a feeding mechanism for a granulator is provided. Utility Model Content

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0025] See Figures 1-4This embodiment provides a feeding mechanism for a granulator, including a housing 1. A triggering device 2 for separating defective products from the housing 1 is mounted on the top of the housing 1. The triggering device 2 includes a first rotating rod 21, which is rotatably connected to the front of the inner wall of the housing 1 via a bearing. The first rotating rod 21 extends movably through the housing 1 towards the front. A motor 212 is fixedly connected to the front of the housing 1. A filter plate 22 is fixedly sleeved on the outer wall of the first rotating rod 21. A striking assembly for striking the filter plate 22 is mounted on the front of the housing 1. A fixing plate 28 is fixedly connected to the side of the inner wall of the housing 1, and two limiting rods 29 are fixedly connected to the top of the fixing plate 28. A float plate 210 is slidably connected to the outer wall of the limiting rod 29. A switch 211 is fixedly connected to the side of the inner wall of the box 1. The extension end of the first rotating rod 21 is fixedly connected to the output end of the motor 212. The striking assembly includes a rack 23, which is fixedly connected to the front of the inner wall of the box 1. A vertical plate 24 is fixedly connected to the top of the filter plate 22. A second rotating rod 25 is rotatably connected to the front of the vertical plate 24 through a bearing. A spur gear 27 is fixedly connected to the back of the second rotating rod 25. A striking block 26 is fixedly connected to the front of the second rotating rod 25. The spur gear 27 meshes with the rack 23. The striking block 26 is elliptical. The motor 212 is electrically connected to the switch 211.

[0026] In practical use, the above equipment is placed at the discharge port of the granulator. Water is filled into the box 1. When unqualified products block the filter plate 22, the water level rises and drives the float 210. The float 210 slides on the outer wall of the limit rod 29. The float 210 squeezes the switch 211, which drives the motor 212 to open. The motor 212 drives the first rotating rod 21 to rotate. The first rotating rod 21 drives the filter plate 22 to rotate counterclockwise. The filter plate 22 drives the vertical plate 24 to rotate. The vertical plate 24 drives the second rotating rod 25, the sprocket 27, and the striking block 26 to rotate. During the movement, the sprocket 27 rotates through the rack 23. The sprocket 27 drives the second rotating rod 25 to rotate. The second rotating rod 25 drives the striking block 26 to rotate and strike the filter plate 22, thereby tilting the filter plate 22 and causing it to vibrate, which moves the unqualified products toward the discharge port. Example

[0027] See Figures 1-4Based on Embodiment 1, the side of the housing 1 is equipped with a feeding device 3 for discharging unqualified products during the lifting of the filter plate 22. The feeding device 3 includes a hydraulic chamber 31, which is fixedly connected to the top of the inner wall of the housing 1. A first hydraulic rod 32 is slidably connected to a piston at one end inside the hydraulic chamber 31, and a second hydraulic rod 33 is slidably connected to a piston at one end inside the hydraulic chamber 31. A door 34 is fixedly connected to the right side of the second hydraulic rod 33. A slide rail 35 for the movement trajectory of the door 34 is fixedly connected to the side of the housing 1. The door 34 is slidably connected to the inner wall of the slide rail 35. A sealing gasket 36 is fixedly connected to the side of the housing 1. The first hydraulic rod 32 is fixedly connected to the top of the filter plate 22.

[0028] In practical use, when the filter plate 22 rotates counterclockwise, it drives the first hydraulic rod 32. When the first hydraulic rod 32 moves to the left, the internal pressure of the hydraulic chamber 31 increases, which drives the second hydraulic rod 33 to descend. The second hydraulic rod 33 drives the door 34 to descend. The sliding rail 35 limits the movement trajectory of the door 34. Through the linkage between the door 34 and the filter plate 22, the automatic discharge of the device is improved. When the discharge of unqualified products is completed, the water level drops, the float plate no longer presses the switch 211, and the switch 211 drives the motor 212 and the filter plate 22 to return to their original positions.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
