Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch processing, in particular to a plastic masterbatch particle screening device. Background Art

[0002] Plastic masterbatch (also called masterbatch or plastic masterbatch) is an additive widely used in the process of plastic processing and molding. Plastic masterbatch is a plastic processing additive composed of excess chemical additives, carrier resins and dispersants. It is made by mixing and kneading the required various additives, fillers and a small amount of carrier resin before plastic processing and molding, and undergoing a series of processing processes. In the production process of plastic masterbatch, it is necessary to screen the plastic masterbatch. The screening can adjust the aperture size of the sieve as needed to obtain the plastic masterbatch particle size range that meets the requirements. Plastic masterbatch with uniform particle size is easier to be evenly dispersed in the plastic matrix in subsequent processing to avoid problems such as agglomeration and stratification.

[0003] After searching, a plastic masterbatch screening device, application number: CN202121116622.2, is found. It conveys and screens the plastic masterbatch through an inclined conveyor belt. Although a tipping hopper is provided on the left side of the conveying component, the plastic masterbatch with a larger volume on the surface of the conveyor belt will still slide to the left and fall around the device. The device is not convenient for screening large quantities of plastic masterbatch. The scattered plastic masterbatch pollutes the surrounding working environment. Moreover, after the screening is completed, the staff also needs to recycle and clean the plastic masterbatch that has fallen around, and the screening effect is poor. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 As shown, a plastic masterbatch particle screening equipment comprises two fixed frames 1, and the surfaces of the fixed frames 1 facing each other are rotatably connected with a plurality of connecting plates 2, and a receiving box 3 is arranged above the surfaces of the connecting plates 2 facing each other, and a plurality of brackets 4 are fixed to the surface of the top of the receiving box 3, and a screening plate 5 is fixed above the bracket 4, and a discharge plate 6 is fixed to the left side of the screening plate 5, a fixed platform 7 is installed below the fixed frame 1, and a driving structure 8 is fixed to the top of the fixed platform 7, and movable plates 9 are arranged below the surfaces of the connecting plates 2 facing each other, and a connecting platform 10 is fixed to the middle part of the surfaces of the movable plates 9 facing each other, and a mounting seat 11 is fixed to the right side of the fixed frame 1, and a supporting frame 12 is bolted to the top of the mounting seat 11, and a lifting structure 13 is fixed to the top of the supporting frame 12, and a material discharge hopper 14 is slidably connected to the bottom of the inner wall of the supporting frame 12.

[0025] The driving structure 8 includes a motor 81, a driving wheel 82, a fixed seat 83, a rotating shaft 84, a driven wheel 85 and a push rod 86. The motor 81 is fixed to the right side of the top of the fixed platform 7, the driving wheel 82 is fixed to the front end of the output shaft of the motor 81, the fixed seat 83 is fixed to the front and rear of the left side of the top of the fixed platform 7, the rotating shaft 84 is rotatably connected between the fixed seats 83, the driven wheel 85 is rotatably connected to the surface of the front fixed seat 83, the front end of the rotating shaft 84 passes through the front fixed seat 83 and is fixedly connected to the driven wheel 85, the driven wheel 85 is connected to the driving wheel 82 through a belt, the push rod 86 is movably connected to the surface of the rotating shaft 84, and the other end of the push rod 86 is hinged to the surface of the connecting platform 10. When the motor 81 is turned on, the output shaft of the motor 81 drives the driving wheel 82 to rotate, and the driven wheel 85 on one side is rotated through the belt, the rotating shaft 84 between the fixed seats 83 rotates, and the push rod 86 starts to move, and the connecting platform 10 is moved back and forth left and right through the push rod 86.

[0026] The connecting plate 2 is tilted as a whole, and the upper and lower sides of the connecting plate 2 are rotatably connected to the movable plate 9 and the material receiving box 3 respectively. When the push rod 86 drives the connecting platform 10 to move, the movable plates 9 on both sides move, and the multiple connecting plates 2 drive the upper material receiving box 3 to swing back and forth, thereby screening the plastic masterbatch on the surface of the screening plate 5.

[0027] The lifting structure 13 includes a hydraulic cylinder 131, a pulley 132 and a lifting belt 133. The hydraulic cylinder 131 is fixed to the bottom of the inner wall of the support frame 12, and the pulley 132 is rotatably connected to the top of the output shaft of the hydraulic cylinder 131. The lifting belt 133 is fixed to the right side of the top of the discharge hopper 14. The lifting belt 133 is in contact with the pulley 132, and the end of the lifting belt 133 away from the discharge hopper 14 is fixedly connected to the bottom of the inner wall of the support frame 12. When the staff puts the plastic masterbatch to be screened into the discharge hopper 14, the hydraulic cylinder 131 on one side is opened, so that the output shaft of the hydraulic cylinder 131 pushes the pulley 132 to move upward, so that one end of the lifting belt 133 pulls the discharge hopper 14 to rise, and the plastic masterbatch is lifted and processed. When the height of the discharge hopper 14 is higher than the height of the screening plate 5, the staff closes the hydraulic cylinder 131, and then the plastic masterbatch in the discharge hopper 14 can be poured onto the screening plate 5 for subsequent screening operations.

[0028] The surfaces of the front and rear sides of the discharge hopper 14 are rotatably connected to two guide wheels 15, and the guide wheels 15 are located inside the support frame 12 and are rollingly connected to the inner wall of the support frame 12. When the hydraulic cylinder 131 is opened, the guide wheels 15 on both sides can guide the discharge hopper 14, thereby improving the stability of the discharge hopper 14 when it moves up and down.

[0029] Working principle: When the staff needs to screen the plastic masterbatch, the staff first opens the hydraulic cylinder 131 on one side, so that the output shaft of the hydraulic cylinder 131 drives the pulley 132 to descend, so that the discharge hopper 14 descends, and then the staff can pour the plastic masterbatch on top of the discharge hopper 14, and then use the hydraulic cylinder 131 again to make the discharge hopper 14 rise and its height is higher than the screening plate 5, and then the staff can pour the plastic masterbatch on top of the screening plate 5. At this time, the staff turns on the motor 81, so that the screening plate 5 swings back and forth, and moves the plastic masterbatch to the left. When the plastic masterbatch moves above the screening plate 5, the smaller plastic masterbatch will pass through the screening plate 5 and fall into the receiving box 3 below, while the larger plastic masterbatch will continue to move to the left, and then the screened plastic masterbatch will be discharged through the unloading plate 6, and then the staff will take out the plastic masterbatch in the receiving box 3, thereby completing the screening of the plastic masterbatch.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
