Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulation equipment technology, specifically to an extrusion granulation device for masterbatch. Background Technology
[0002] Plastic granulators are mainly used to process waste plastic films, woven bags, agricultural convenience bags, basins, buckets, beverage bottles, furniture, daily necessities, etc., and are suitable for most common waste plastics.
[0003] Currently, in the extrusion production process of pre-dispersed rubber additive masterbatch, it is inconvenient to cut the formed round strips into pellets and it is difficult to cool them in time. The prior art patent with publication number CN220373668U discloses an open-ended slip masterbatch extrusion granulation device, which includes a cooling tank. The top of the cooling tank is vertically mounted with a mounting frame, and the top of the mounting frame is horizontally mounted with a fixing plate. The fixing plate is equipped with a cutting component. The cooling tank is horizontally inclined with a transport component. The cooling tank is horizontally mounted with a filter plate near the bottom and a circulation component is set at the bottom of the cooling tank. The side wall of the mounting frame is equipped with an extrusion mechanism. The device is configured to spray water on the falling material through a support body. When the material falls onto the bottom of the transport mechanism, the material is cooled in the cooling tank. Then, the transport mechanism is started to rotate and transport the material on top out of the cooling tank, thereby achieving the purpose of cooling the material.
[0004] However, in the above technical solution, since the formed round bar has a certain temperature, when the cutting component cuts it, the masterbatch is easily stuck to the surface of the cutter, which affects the cutting effect of the cutter. Sometimes it is necessary to stop the machine for treatment, resulting in a reduction in cutting efficiency. Utility Model Content

However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0017] See attached diagram. Figures 1 to 4 In this embodiment, an extrusion granulation device for masterbatch includes a frame 1, an extrusion device 2 is mounted on the frame 1, and a cold water tank 3 is provided below the extrusion device 2; a mounting plate 4 is provided on the frame 1, and a cutting assembly is provided on the mounting plate 4; a support plate 41 is provided at the bottom of the mounting plate 4, and a cold water box 8 is provided on the support plate 41.
[0018] In the above scheme, the cutting assembly includes a drive motor 40 installed on one side of the mounting plate 4. The output end of the drive motor 40 is provided with a turntable 5, and the turntable 5 is provided with an eccentric shaft 50. A first connecting rod 6 is provided on one side of the turntable 5. A first sliding groove 60 and a second sliding groove 61 are provided on the first connecting rod 6. The eccentric shaft 50 is slidably connected to the first sliding groove 60. A first connecting shaft 71 is slidably arranged in the second sliding groove 61. A second connecting rod 7 is provided at one end of the first connecting shaft 71. A third sliding groove 72 is provided at one end of the second connecting rod 7. A rotating shaft 70 is provided at the middle position of the second connecting rod 7. One end of the rotating shaft 70 is connected to the mounting plate 4.
[0019] In the above scheme, a first vertical rod 74 is hinged to one end of the second connecting rod 7 near the first connecting rod 6; a second connecting shaft 73 is slidably arranged in the third slide groove 72, and a second vertical rod 75 is provided at one end of the second connecting shaft 73; a cutter 740 is provided at the bottom end of the first vertical rod 74, and the cutter 740 is located above the outlet end of the extrusion device 2; a horizontal plate 750 is provided at the bottom end of the second vertical rod 75, and a scraper 751 is installed on the end of the horizontal plate 750 facing the cutter 740; a scraper 752 is provided on the scraper 751, and the scraper 752 is used to scrape off the masterbatch remaining on the surface of the cutter 740.

[0022] Working principle: In the cutting assembly, the drive motor 40 drives the turntable 5 to rotate. The eccentric shaft 50 on the turntable 5 is slidably connected to the first groove 60 of the first connecting rod 6. The movement of the eccentric shaft 50 drives the first connecting rod 6 to rotate in a plane. The second groove 61 on the first connecting rod 6 cooperates with the first connecting shaft 71 to transmit the motion to the second connecting rod 7. The second connecting rod 7 swings around the central rotating shaft 70 as the fulcrum, so that the first vertical rod 74 and the second vertical rod 75 connected to the second connecting rod 7 can stably reciprocate up and down alternately. That is, when the first vertical rod 74 drives the cutter 740 to complete one cut and move upward, the second vertical rod 75 can drive the scraper 751 and the scraper 752 to move downward and scrape off the masterbatch remaining on the surface of the cutter 740.
[0023] The cold water box 8 on the mounting plate 41, together with the water pump and the conduit 80, can accurately spray cold water onto the cutter 740 to cool the cutter 740 and the scraper 752, making it easier for the cut masterbatch to fall into the cold water pool 3 for cooling.
[0024] It should be noted that in this embodiment, both the extrusion device 2 and the cold water tank 3 can be considered as existing technology.
[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
