Technical Field

[0001] The utility model belongs to the technical field of PP plastic processing, and more specifically, particularly relates to a material feeding and screening structure for a PP modified material processing granulator. Background Art

[0002] PP modified material is a special PP plastic formed by adding flame retardants, stone powder or mica / borax, or glass fiber GF to PP raw materials. It is mainly used to produce polypropylene woven bags, packaging bags, injection molded products, etc. for the production of flame-retardant parts for electrical appliances, telecommunications, lighting, lighting equipment and televisions. During the production and processing of PP modified materials, the raw materials need to be granulated to improve the quality of the raw materials. Before the granulated PP modified materials are melted, they usually need to be screened to remove the impurities inside to avoid the impurities affecting the performance of the products.

[0003] Based on the above, the inventors have found the following problems: the current feeding and screening structures of PP modified material processing and granulating machines mostly use a vibration motor to drive the screen plate to mechanically vibrate to screen the PP modified material. During the screening process of the PP modified material, when the screen plate runs for a long time or too much material is accumulated, the material may be blocked on the screen, making it impossible to discharge the material, thereby reducing the screening efficiency of the PP modified material.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a PP modified material granulator is provided to achieve a more practical purpose. Utility Model Content

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a feeding and screening structure for a PP modified material processing granulator, comprising a main body 100 and a fixing mechanism 200, wherein the main body 100 comprises a base frame 1001, a granulator 1002 is installed on the upper end of the base frame 1001, and a pair of support frames 1003 are installed on the top of the base frame 1001, a screening box 1004 is installed between the pair of support frames 1003, a feeding port 1005 is installed on the upper end of the screening box 1004, a filter plate 1006 is arranged inside the feeding port 1005, a plurality of jacks 1008 are provided on both sides of the filter plate 1006, and a pair of long plates 300 are installed on one side of the inner wall of the screening box 1004 1. A pair of long plates 3001 are provided with a horizontal plate 3002 at their upper ends, a pair of mounting seats 3003 are provided at their upper ends, a pair of mounting seats 3003 are provided with sliding rods 3004 movably inserted inside, a pair of sliding rods 3004 are provided with a moving seat 3005 at their upper ends, a plurality of insertion pins 3006 are provided at their upper ends, a plurality of insertion pins 3006 are provided at their upper ends, a plurality of insertion pins 3006 are provided to penetrate the filter holes of the filter plate 1006, and extend to the outside of the filter plate 1006, by providing the insertion pins 3006, when the insertion pins 3006 are inserted into the filter plate 1006 and then retracted, the filter hole is prevented from being blocked, and the raw materials on the filter plate 1006 are convenient to fall.

[0027] Among them, the cross plate 3002 is equipped with a retaining frame near the top of a pair of mounting seats 3003, and the upper end of the retaining frame is equipped with a motor 3007. The output end of the motor 3007 is rotatably connected to a crank 3008. By setting the motor 3007, when it is working, it is convenient to drive the crank 3008 to rotate.

[0028] Among them, one side of the crank 3008 is rotatably connected to the connecting rod 3009 through a pin shaft, and the connecting rod 3009 is connected to the movable seat 3005 through a pin shaft at the end away from the crank 3008. By connecting the crank 3008 and the connecting rod 3009 through a pin shaft, when the crank 3008 rotates, the connecting rod 3009 moves. Since the connecting rod 3009 is connected to the movable seat 3005 through the pin shaft, the movable seat 3005 makes reciprocating motion under the action of the sliding rod 3004 and the mounting seat 3003.

[0029] Among them, the fixing mechanism 200 includes a pair of mounting plates 2001, and the pair of mounting plates 2001 are respectively arranged on the outside of the loading port 1005, and a pair of fixing rods 2002 are installed on one side of the pair of mounting plates 2001. A slide plate 2004 is slidably sleeved between the pair of fixing rods 2002. The slide plate 2004 is installed with a plurality of plug rods 2005 on the side away from the mounting plate 2001. The plug rods 2005 pass through the loading port 1005 and are plugged into the socket 1008. By setting the slide plate 2004, when the slide plate 2004 is pulled, the slide plate 2004 moves on the fixing rod 2002, so that the plug rod 2005 is separated from the socket 1008 of the filter plate 1006.

[0030] Among them, a pair of fixed rods 2002 are movably sleeved on the outside with springs 2003, one end of the spring 2003 is fixedly connected to the mounting plate 2001, and the spring 2003 is fixedly connected to the slide plate 2004 at the end away from the mounting plate 2001. By setting the spring 2003, when the slide plate 2004 is pulled to separate the insertion rod 2005 from the socket 1008, the slide plate 2004 squeezes the spring 2003. When the slide plate 2004 is released, the slide plate 2004 can restore the insertion rod 2005 to its original position under the elastic force of the spring 2003.

[0031] A pair of handles 1007 are installed at the upper end of the filter plate 1006 , and a plurality of anti-slip textures are provided on the outside of the pair of handles 1007 . The filter plate 1006 can be easily taken out by providing the handles 1007 .

[0032] A feed port 1009 is installed at the bottom of the screening box 1004 , and the feed port 1009 is connected to the feed port of the granulator 1002 through a connecting pipe.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When using this product, first check whether the internal mechanisms of the feeding and screening structure of the PP modified material processing granulator are complete. After ensuring that they are complete, pour the raw materials to be granulated into the feeding port 1005. At this time, the raw materials fall on the filter plate 1006. By starting the motor 3007, the crank 3008 is driven to rotate, so that the connecting rod 3009 moves. Since the connecting rod 3009 is connected to the movable seat 3005 by a pin shaft, the movable seat 3005 reciprocates under the action of the slide bar 3004 and the mounting seat 3003, so that the pin 3006 installed on the upper end of the movable seat 3005 continuously passes through the filter plate 1006, avoiding clogging of the filter holes. The raw material on the filter plate 1006 falls, and the upper end of the movable seat 3005 is arc-shaped, which is convenient for guiding the raw material and making it fall into the discharge port 1009. Since the discharge port 1009 is connected with the feed port of the granulator 1002 through the connecting pipe, the raw material falls into the interior of the granulator 1002. By starting the granulator 1002, the raw material is squeezed, sheared and rubbed to gradually form particles of a certain shape and specification. When the filter plate 1006 needs to be taken out, the slide plate 2004 is pulled to separate the insertion rod 2005 from the insertion hole 1008, and the filter plate 1006 is taken out by the handle 1007, and the filter plate 1006 is cleaned and replaced.
