Description

Technical Field

[0001] This utility model relates to the field of plastic granulation machine technology, and in particular to a plastic granulation machine for the production of flame-retardant PP material. Background Technology

[0002] Flame-retardant PP material is a plastic particle made from polypropylene as a base, with the addition of flame retardants and other additives, through extrusion processing. In the production of flame-retardant PP material, a plastic granulator is required for granulation. The main working principle of the plastic granulator is to heat, extrude, and granulate the plastic raw material into plastic particles with a certain shape and size through processes such as heating, extrusion, and pelletizing.

[0003] In existing technology, after the raw material is melted and extruded, the plastic granulator requires the operator to pull the raw material through the cooling tank, and then put one end of the extruded raw material into the pelletizing equipment for pelletizing. Since the operator holds one end of the raw material into the pelletizing equipment, it is difficult to align one end of the raw material with the feed port of the pelletizing equipment when putting it in, and it needs to be aligned repeatedly, which increases the cumbersomeness of the pelletizing process. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic granulator for the production of flame-retardant PP materials, so as to solve the problem mentioned in the background art that when the operator puts the raw material into the pelletizing equipment by holding one end, it is difficult to align one end of the raw material with the feed port of the pelletizing equipment, which requires constant alignment and increases the cumbersomeness of the pelletizing process.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes an extrusion device, one side of which is fixedly connected to one side of a cooling mechanism.

The scale collection mechanism includes a mounting frame, an extrusion groove, a connecting spring, a locking block, an extension block, a pulling block, and a collection frame. The side of the cooling mechanism away from the extrusion device is fixedly connected to one side of a pelletizing device.

[0006] In a preferred embodiment, one side of the cooling rack is fixedly connected to one side of the extrusion equipment, and the side of the cooling rack away from the extrusion equipment is fixedly connected to one side of the pelletizing equipment. Sliding grooves are provided on both sides of the inner wall of the cooling rack, and a sealing mounting groove is provided at the bottom of one end of the cooling rack.

[0007] In a preferred embodiment, both sides of the outer wall of the cooling rack are fixedly connected to one side of the stabilizing frame, and a movable groove is provided inside one side of the stabilizing frame, with extension openings at the top of both ends of the movable groove.

[0008] In a preferred embodiment, the movable frame has a spring groove inside, and the inner wall of the spring groove is fixedly connected to both ends of the limiting rod. The inner bottom wall of the spring groove is fixedly connected to the bottom end of the fixed slider, and one side of the fixed slider is fixedly connected to one side of the fixed clamping plate.

[0009] In a preferred embodiment, the inner wall of the spring groove is movably connected to the outer wall of the movable slider, and a limit buckle is provided inside the movable slider.

The outer walls of the fixed slider and the movable slider are movably connected to the inner wall of the movable groove, and the outer wall of the movable slider is movably connected to the inner wall of the extension opening.

[0010] In a preferred embodiment, the outer wall of the cleaning frame is movably connected to the interior of the cooling frame, and both sides of the top of the cleaning frame are fixedly connected to one side of the limiting slider. The bottom outer wall of the cleaning frame is fixedly connected to the top of the cleaning brush, and the outer wall of the cleaning brush contacts the inner wall of the cooling frame. The outer wall of the limiting slider is movably connected to the inner wall of the moving groove.

[0011] In a preferred embodiment, the top of the mounting frame is fixedly connected to the top of the cooling rack away from the extrusion equipment, and the inner wall of the mounting frame is provided with an extrusion groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the movable slider moves to a position near the lower part of the extension port of the pelletizing equipment. The reset spring drives the movable slider to stabilize inside the extension port, thereby stabilizing the movable frame. At the same time, the movable slider moves by the reset spring, so that the movable clamping plate does not squeeze the raw material, allowing one end of the raw material to enter the interior of the pelletizing equipment. The movable frame and the clamping stability of the movable clamping plate facilitate the movement of the raw material and make it easier to align the raw material, reducing the cumbersome process of manually placing the raw material into the pelletizing equipment.

[0014] 2. This utility model features a movable cleaning rack. The cleaning rack moves along the inner wall of the cooling rack via a limiting slider, simultaneously moving the cleaning brush against the inner wall of the cooling rack to clean it. The cleaned scale enters the interior of the collection rack. When the device stops working, the moving pull block moves the extension block, which in turn moves the locking block away from both sides of the collection rack. At the same time, the connecting spring is compressed, thus disassembling the collection rack. The cleaned collection rack is placed between the mounting racks and placed on the inner wall of the sealing mounting groove via a sealing ring. Releasing the pull block causes the connecting spring to reset, causing the locking block to lock the two sides of the collection rack in the groove, thus stabilizing the collection rack. This facilitates the cleaning of the inner wall of the cooling rack and reduces the impact of scale on the quality of raw materials. Attached Figure Description

[0028] Specifically: The movable slider 306 moves away from the inner wall of the extension port 206 near the extrusion device 1 and enters the interior of the movable groove 205, pushing the movable frame 301 to limit the movable slider 306 through the movable groove 205, so that the fixed slider 304 and the movable slider 306 are in a squeezed state when they move inside the movable groove 205.

[0032] Specifically: when the moving frame 301 moves to the feed inlet of the pelletizing device 6, the moving slider 306 moves to a position below the extension port 206 of the pelletizing device 6. The reset spring 308 drives the moving slider 306 to stabilize inside the extension port 206, thereby stabilizing the moving frame 301.

[0033] In one embodiment, the outer wall of the cleaning rack 401 is movably connected to the interior of the cooling rack 201, and both sides of the top of the cleaning rack 401 are fixedly connected to one side of the limiting slider 402. The bottom outer wall of the cleaning rack 401 is fixedly connected to the top of the cleaning brush 403, and the outer wall of the cleaning brush 403 contacts the inner wall of the cooling rack 201. The outer wall of the limiting slider 402 is movably connected to the inner wall of the sliding groove 202.

[0034] Specifically: the movable cleaning rack 401 moves along the inner wall of the cooling rack 201 via the limiting slider 402, while simultaneously driving the cleaning brush 403 to move against the inner wall of the cooling rack 201, thereby cleaning the inner wall of the cooling rack 201. The cleaned scale enters the interior of the collection rack 507.

[0035] In one embodiment, the top end of the mounting frame 501 is fixedly connected to the top end of the cooling rack 201 away from the extrusion device 1, and the inner wall of the mounting frame 501 is provided with an extrusion groove 502. The inner wall of the extrusion groove 502 is fixedly connected to one end of the connecting spring 503, and the other end of the connecting spring 503 is fixedly connected to one side of the locking block 504. The side of the locking block 504 near the connecting spring 503 is fixedly connected to one end of the extension block 505, and the end of the extension block 505 away from the locking block 504 is fixedly connected to one end of the pulling block 506. One side of the mounting frame 501 is movably connected to one side of the collecting rack 507, and both sides of the collecting rack 507 are provided with slots. The inner wall of the slots is movably connected to the outer wall of the locking block 504, and the outer wall of the collecting rack 507 is movably connected to the inner wall of the sealing mounting groove 203. A sealing ring is provided on the top outer wall of the collecting rack 507.

[0036] Specifically: the moving pull block 506 drives the extension block 505 to move, thereby moving the locking block 504 away from both sides of the collection rack 507, while simultaneously squeezing the connecting spring 503, thereby disassembling the collection rack 507. The cleaned collection rack 507 is placed between the mounting racks 501, and simultaneously placed on the inner wall of the sealing mounting groove 203 through the sealing ring. Releasing the pull block 506 causes the locking block 504 to lock the two sides of the slot collection rack 507 through the reset of the connecting spring 503, thereby stabilizing the collection rack 507.

[0037] Working principle: The raw material is melted and extruded through the extrusion device 1. The extruded material first falls into the cooling rack 201 and is cooled by water inside the cooling rack 201. One end of the cooled material is placed between the fixed clamping plate 305 and the movable clamping plate 307. Pressing the movable clamping plate 307 stabilizes one end of the material. The movable clamping plate 307 is compressed, causing the movable slider 306 to press against the return spring 308 by the limiting rod 303. This causes the movable slider 306 to move away from the extension of the extrusion device 1. The inner wall of the inlet 206 enters the interior of the moving groove 205, pushing the moving frame 301 through the moving groove 205 to limit the moving slider 306, so that the fixed slider 304 and the moving slider 306 are in a compressed state when moving inside the moving groove 205. When the moving frame 301 moves to the feed inlet of the pelletizing device 6, the moving slider 306 moves to a position close to the lower part of the extension 206 of the pelletizing device 6. The reset spring 308 drives the moving slider 306 to stabilize inside the extension 206, thereby limiting the movement of the moving frame 306. 1. To stabilize the material, the sliding block 306 moves under the reset of the return spring 308, preventing the moving clamping plate 307 from squeezing the raw material. This allows one end of the raw material to enter the pelletizing equipment 6. During cleaning of the cooling rack 201, the cleaning rack 401 moves along the inner wall of the cooling rack 201 via the limiting slider 402. Simultaneously, the cleaning brush 403 moves against the inner wall of the cooling rack 201, cleaning it. The resulting scale enters the collection rack. Inside 507, when the device stops working, the moving pull block 506 moves the extension block 505, which in turn moves the locking block 504 away from both sides of the collection rack 507, and at the same time squeezes the connecting spring 503, thereby disassembling the collection rack 507. The cleaned collection rack 507 is placed between the mounting racks 501, and at the same time, it is placed on the inner wall of the sealing mounting groove 203 through the sealing ring. Releasing the pull block 506 causes the locking block 504 to lock the two sides of the slot collection rack 507 through the reset of the connecting spring 503, thereby stabilizing the collection rack 507.
