Description

Technical Field

[0001] The present application relates to the technical field of pelletizing processing, and in particular to a pelletizer powder collection device. Background Art

[0002] Plastic granulation is a process of plastic mechanical processing. The size of the particles formed is related to factors such as the rotation speed of the granulator.

[0003] A pelletizer is a mechanical material processing equipment, and its main function is to cut various materials into granules or small pieces. The pelletizer is equipped with a cutter, which includes a moving knife and a fixed knife. The pelletizing is achieved through the cooperation of the moving knife and the fixed knife.

[0004] However, if the weight of the material is small or the material stays at the cutter for too long, the cutter will repeatedly cut the material, thus forming pellets. The pellets will fly in the pelletizer due to vibration and static electricity, enter the gap between the cutter and the pelletizer, and accumulate, which is not easy to clean, and will also affect the service life of the pelletizer and increase costs.

[0005] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that the cut powder in the pelletizer is difficult to clean. Utility Model Content

[0040] The following is combined with Figure 1-Figure 3 The present application is further described in detail. In this embodiment, if not clearly specified, "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, etc., which can be understood according to the specific circumstances. In the absence of any contrary explanation, the directional words used in this application, such as "inside" and "outside", refer to the outline of the corresponding parts themselves.

[0041] like Figure 1 As shown, the embodiment of the present application discloses a pelletizer powder collection device (hereinafter referred to as "device"), which includes a filtering component 1, a collecting component 2 and a suction component. The pelletizer is used to cut the material into pellets. The pelletizer includes a pelletizing box 100, a supporting structure 200, a driving structure 300, a control structure 400 and a discharge port 500. In view of the existing related mechanical equipment, its specific structure and connection relationship will not be repeated here.

[0042] The filter assembly 1 is arranged at the bottom of the pelletizing box 100 of the pelletizer, and the collecting assembly 2 is arranged below the filter assembly 1, so that the filter assembly 1 can be covered on the collecting assembly 2, so that the pelletized powder can be discharged from the pelletizing box through the filter assembly 1, reducing the pelletized powder content in the pelletizing box, improving the cleanliness inside the pelletizer, and extending the service life of the pelletizer. The discharged pelletized powder directly enters the collecting assembly 2, thereby realizing the timely collection of the pelletized powder, reducing the degradation of the processing environment quality of the pelletizer caused by the flying of the pelletized powder, reducing the difficulty of cleaning and collecting the pelletized powder, and reducing the labor intensity.

[0043] like Figure 1 and Figure 2 As shown, the suction assembly is vertically arranged between the filter assembly 1 and the collection assembly 2, and the suction assembly is used to suck air from the upper side of the filter assembly 1 to the lower side of the filter assembly 1, thereby improving the flow efficiency of the cut powder and accelerating the discharge of the cut powder generated in the pelletizing box 100.

[0044] The pelletizing box 100 includes a pelletizing box 110, a conveying member 120 and a pelletizing member 130. The conveying member 120 and the pelletizing member 130 are arranged in the pelletizing box 110, and the conveying member 120 and the pelletizing member 130 are rotatably connected to the pelletizing box 110. The conveying member 120 can be a conveying roller group, which drives the material to move to the pelletizing member 130; the pelletizing member 130 can be a movable knife, and the pelletizing box 110 is also fixed with a fixed knife, and the pelletizing is achieved by the cooperation of the rotating movable knife and the fixed knife. The filter component 1 is arranged below the pelletizing member 130; in this embodiment, the filter component 1 can be arranged at the connection between the bottom and the side wall of the pelletizing box 110, and is arranged on the side of the pelletizing member 130 away from the conveying member 120, which is located in the output direction of the pelletizing member 130 after pelletizing, and it is easy to accumulate the light weight pellets. Since the chips are formed after pelletizing by the pelletizing element 130, they are easy to fall directly under the pelletizing element 130 or settle under the pelletizing element 130 after flying. Placing the filter assembly 1 under the pelletizing element 130 helps to improve the collection effect of the chips.

[0045] like Figure 1-Figure 3 As shown, the filter assembly 1 includes a filter plate 11, and a filter hole is provided on the filter plate 11. The diameter of the pellets is larger than the diameter of the powder, and the diameter of the filter hole is larger than the diameter of the powder but smaller than the diameter of the pellets, so that the pellets remain in the pelletizing box 100 for product output and collection, and the powder can be collected in the collection assembly 2 through the filter hole, which effectively cleans the powder without affecting the output of the pelletized product.

[0046] Optionally, the filter plate 11 is slidably connected to the bottom of the pelletizing box 100, and a pulling member 12 is provided on the filter plate 11. One end of the pulling member 12 away from the filter plate 11 is movably penetrated through the side wall of the pelletizing box 100, and the filter plate 11 can be slid out by driving the pulling member 12, so as to facilitate cleaning of the filter plate 11 and avoid affecting the collection effect of pelletized powder due to the pelletized powder blocking the filter holes.

[0047] like Figure 1-Figure 3 As shown, the filter assembly 1 further includes a cleaning member 13, which is slidably connected to the filter plate 11, and the length of the cleaning member 13 is greater than or equal to the length of the filter plate 11. The cleaning member 13 can be a brush or a scraper, and the filter plate 11 can be cleaned by relative movement between the cleaning member 13 and the filter plate 11 to avoid excessive accumulation of cut powder or pellets on the filter plate 11, so that the filter assembly 1 and the suction assembly can reliably discharge the cut powder from the pelletizing box 100; and the pellets can be moved outside the filter plate 11 to avoid the pellets falling into the collection assembly 2 when the filter plate 11 is pulled out, thereby affecting the collection of the pelletized products.

[0048] Optionally, a push-pull member 14 is provided on the cleaning member 13, one end of the push-pull member 14 is connected to the cleaning member 13, and the other end of the push-pull member 14 is movably provided on the side wall of the pelletizing box 100. By moving the push-pull member 14, the cleaning member 13 is driven to move on the filter plate 11, so that the filter plate 11 can be cleaned in the pelletizing box 100 when the filter plate 11 is installed in the pelletizing box 100. The push-pull member 14 can be a handle, a handle or a rod-shaped structure, and the side wall of the pelletizing box 100 is provided with a through groove, and the push-pull member 14 is provided in the through groove, so as to achieve reciprocating movement and clean the filter plate 11.

[0049] like Figure 1-Figure 3 As shown, the collecting assembly 2 includes a guide, a collecting box 22 and a connecting member 23. The upper end of the connecting member 23 is slidably connected to the pelletizing box 100, so as to facilitate the disassembly of the collecting assembly 2 and clean the device.

The connecting member 23 can be a cylindrical structure, and the connecting member 23 extends in the vertical direction, so that there is a certain vertical distance between the filter assembly 1 and the guide, thereby reducing the wind force of the suction assembly on the guide, and reducing the risk of the pellets on the guide flying toward the filter assembly 1 due to the direct blowing of the suction assembly.

[0050] The guide is tilted downward, the upper end of the guide is arranged below the suction assembly, the collection box 22 is connected to the output end of the guide, and the collection box 22 is arranged on one side of the guide, the chips are sent into the guide through the suction assembly, and further collected in the collection box 22. Since the collection box 22 is arranged on one side of the guide, the risk of excessive flying of the chips in the collection box 22 due to the direct blowing of the suction assembly can be reduced, and the reliability of chip collection can be improved.

[0051] like Figure 1-Figure 3 As shown, the guide member includes a first guide portion 211 and a second guide portion 212. The first ends of the first guide portion 211 and the second guide portion 212 are both arranged at the lower end of the connecting member 23 to guide the cut powder so that the cut powder moves into the collection box 22 on one side of the guide member. The second end of the first guide portion 211 is connected to the bottom of the collection box 22, and the first end of the second guide portion 212 is also connected to the top of the collection box 22, and the second end of the second guide portion 212 is inclined toward the inside of the collection box 22, so that the vertical distance between the second end of the second guide portion 212 and the bottom of the collection box 22 is less than the height of the collection box 22, which helps to alleviate the problem of the cut powder entering the collection box 22 flying back to the filter assembly 1 and optimize the collection effect. The guide member and the connecting member 23 can be detachably connected or fixedly connected, and the connection method is not limited; the collection box 22 and the guide member can be fixedly connected, and the bottom of the collection box 22 can be provided with a detachable or flippable bottom plate to facilitate cleaning of the cut powder in the collection box 22.

[0053] The implementation principle of a pelletizer powder collection device in the embodiment of the present application is as follows: while pelletizing in the pelletizing box 100, powder is generated, and the driving member 32 drives the fan member 33 to rotate, so that the powder above the filter plate 11 falls into the collection component 2 through the filter hole; under the guiding action of the guide member and the blowing of the fan member 33, the powder moves to the collection box 22, and under the blocking of the second guide part 212, the problem of the powder flowing back to the filter component 1 is effectively alleviated, and reliable collection of the powder is achieved. When cleaning the device, the cleaning of the device and the cleaning of the powder can be achieved by disassembling the collection component 2, disassembling the bottom plate of the collection box 22, pulling out the filter plate 11, and moving the cleaning member 13. The device automatically cleans and collects the powder in the pelletizing box 100, which can improve the processing efficiency of the powder, reduce labor intensity, save labor, and improve the efficiency of pelletizing operations and the quality of pelletizing products.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
