Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically a screening device for the production of black masterbatch. Background Technology

[0002] Screening devices for black masterbatch production are specifically designed for grading, removing impurities, and screening raw materials or finished products during the black masterbatch production process. Their core function is to remove impurities from materials and separate them according to particle size, ensuring the uniformity and purity of the black masterbatch's particle size, thereby guaranteeing the stability of subsequent processing and product quality. Currently, screening devices for black masterbatch include vibrating screens, ultrasonic screens, and drum screens. Vibrating screens are the most commonly used device in existing technology. However, when using a vibrating screen, the mechanical vibration of the vibrating motor and the high-frequency impact of the material on the screen generate noise of 85-100 decibels. Long-term operation can easily lead to hearing fatigue for operators, requiring additional investment in sound insulation facilities and increasing equipment costs.

[0003] A screening device for the production of black masterbatch is proposed to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a screening device for the production of black masterbatch, in order to solve the problem mentioned in the background art. In the existing technology, the devices for screening black masterbatch are divided into: vibrating screen, ultrasonic screen and drum screen. Among them, the vibrating screen is a commonly used device in the prior art. However, when using the vibrating screen, the mechanical vibration of the vibrating motor and the high-frequency impact of the material and the screen will generate noise of 85-100 decibels. Long-term operation can easily lead to hearing fatigue of the operator, requiring additional investment in sound insulation facilities and increasing equipment costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for the production of black masterbatch, comprising a support base, wherein a box is fixedly installed in the middle of the top surface of the support base;

[0006] The top surface of the box is connected to both sides of the feed pipe, the top surface of the box is fixedly installed in the middle, the two sides of the box are symmetrically opened with several movable slots, the bottom surface of the box is connected to the middle of the discharge pipe, the discharge pipe is fixedly installed inside the discharge pipe, and the discharge pipe is connected to the support base.

[0007] Also includes:

[0008] Several screening components are symmetrically arranged on both sides of the box body;

[0009] The screening component includes a fixing block that is fixedly connected to the housing;

[0010] An electric push rod is fixedly installed on one side of the bottom surface of the fixed block.

[0011] Preferably, a connecting block is fixedly connected to the bottom surface of the electric push rod, a slide rod is connected through one side of the connecting block, and a buffer spring is sleeved on the surface of the slide rod.

[0012] Preferably, the top surface of the buffer spring is fixedly connected to the connecting block, and the bottom surface of the buffer spring is fixedly connected to a stabilizing block.

[0013] Preferably, the top surface of the slide rod is fixedly connected to the fixing block, and the bottom surface of the slide rod is fixedly connected to the stabilizing block.

[0014] Preferably, a screen is fixedly connected to one side surface of the connecting block, and baffles are symmetrically installed on both sides of the screen.

[0015] Preferably, the movable groove is slidably connected to the connecting block.

[0016] Preferably, a spiral conveyor paddle is fixedly connected to the output end of the stepper motor through one side surface of the housing, and a guide plate is fixedly installed inside the housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This screening device for black masterbatch production, through its screening components, reduces noise to a certain extent, limiting the noise generated by the collision between the material and the screen, thereby reducing auditory fatigue for operators. The specific details are as follows:

[0018] 1. By setting up a screening device, when the black material falls onto the screen through the guide plate, the two electric push rods located above are simultaneously activated via the control terminal. The output ends of the electric push rods drive the connecting block downwards, causing it to slide on the slide bar. Simultaneously, the sliding of the connecting block compresses the buffer spring, causing it to deform. The buffer spring can be made of a suitable material according to actual usage, thereby extending its service life. This allows the buffer spring to provide a certain degree of auxiliary cushioning from the side. Furthermore, the descent of the connecting block also causes the screen and baffle to descend, and the outer walls of the screen and baffle are fitted tightly against the inner wall of the housing, thus preventing the black masterbatch from falling out. Simultaneously, when the output end of the electric push rod rises, it drives the connecting block, screen, and baffle to rise, thereby realizing the up-and-down reciprocating motion of the screen and thus playing a screening role for the black masterbatch. At the same time, when the two electric push rods located above are activated, the control end can also activate the two electric push rods located below. When the output ends of the two electric push rods located above extend downward, the output ends of the two electric push rods located below are retracted. When the output ends of the two electric push rods located above are retracted, the output ends of the two electric push rods located below extend upward. Thus, the two electric push rods located above and the two electric push rods located below can perform up-and-down reciprocating motion on two screens with different aperture sizes, thereby enabling multi-stage screening of the black masterbatch.

[0019] 2. By setting up a stepper motor, a screw conveyor, and a guide plate, after the black masterbatch is poured into the box through the feed pipe, it falls onto the guide plate. The surface of the guide plate has a certain slope, which allows the black masterbatch to slide down the slope into the holes on the guide plate and then fall onto the screen. At the same time, the stepper motor is started by the control terminal, and the output of the stepper motor drives the screw conveyor to rotate. The rotation of the screw conveyor can play a certain role in conveying the black masterbatch, thereby avoiding blockage when the black masterbatch falls. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a screening device for black masterbatch production, including a support base 1, a box 2 fixedly installed in the middle of the top surface of the support base 1; a feed pipe 3 is connected through both sides of the top surface of the box 2, a stepper motor 4 is fixedly installed in the middle of the top surface of the box 2, several movable slots 6 are symmetrically opened on both sides of the box 2, a discharge pipe 7 is connected through the middle of the bottom surface of the box 2, a valve 8 is fixedly installed inside the discharge pipe 7, and the discharge pipe 7 is connected through the support base 1; it also includes: several screening components 5 symmetrically arranged on both sides of the box 2; wherein, the screening component 5 includes a fixing block 501 fixedly connected to the box 2; wherein, an electric push rod 502 is fixedly installed on one side of the bottom surface of the fixing block 501, such as Figure 1-5 As shown, the screening component 5 reduces noise to a certain extent, as the noise generated is limited by the collision between the material and the screen, thereby reducing the occurrence of auditory fatigue for operators. At the same time, the box 2 is equipped with a door, which is hinged to the box 2, and a seal is provided between the door and the box 2.

[0028] A connecting block 503 is fixedly connected to the bottom surface of the electric push rod 502. A slide rod 504 is connected through one side of the connecting block 503. A buffer spring 505 is sleeved on the surface of the slide rod 504. The top surface of the buffer spring 505 is fixedly connected to the connecting block 503. A stabilizing block 506 is fixedly connected to the bottom surface of the buffer spring 505. The top surface of the slide rod 504 is fixedly connected to the fixing block 501. The bottom surface of the slide rod 504 is fixedly connected to the stabilizing block 506. A screen 507 is fixedly connected to one side surface of the connecting block 503. Baffles 508 are symmetrically installed on both sides of the screen 507. The movable groove 6 is slidably connected to the connecting block 503. Figure 2 , 4 As shown, the two electric push rods 502 located at the top are synchronously activated by the control terminal. The output end of the electric push rod 502 drives the connecting block 503 to descend, causing the connecting block 503 to slide on the slide rod 504. Simultaneously, the sliding of the connecting block 503 compresses the buffer spring 505, causing it to deform. The buffer spring 505 can be made of a suitable material according to actual usage, thereby extending its service life. The buffer spring 505 provides a certain auxiliary cushioning effect from the side. Simultaneously, when the connecting block 503 descends, it drives the screen 507 and baffle 508 to descend as well. The outer walls of the screen 507 and baffle 508 are in close contact with the inner wall of the housing 2, preventing the black masterbatch from falling. When the output end of the electric push rod 502 rises, it drives the connecting block 503, screen 507, and baffle 508 to rise, thus achieving the desired effect. The reciprocating motion of screen 507 effectively screens the black masterbatch. The connecting block 503 is bolted to screen 507, facilitating disassembly. The electric push rod 502 (model DYTZ450- / 110) is electrically connected to the control terminal and is directly driven by a motor. Power is transmitted through a screw, gears, and other mechanical structures. The control signal directly affects the motor's speed and direction. The motor has a fast response and can correct positional deviations in real time through closed-loop control. There is virtually no lag due to medium compression; it is only slightly affected by mechanical transmission clearance and motor starting inertia. The extension speed of the output end of the electric push rod 502 can be adjusted via the control terminal, thus driving the screen 507 to reciprocate and screen the black masterbatch. The screen 507 can be made of a suitable material depending on the specific requirements.

[0029] A spiral conveyor paddle 9 is fixedly connected to one side surface of the housing 2 through the output end of the stepper motor 4. A guide plate 10 is fixedly installed inside the housing 2. Figure 3 ,5 As shown, by setting a stepper motor 4, a screw conveyor 9, and a guide plate 10, after the black masterbatch is poured into the box 2 through the feed pipe 3, the black masterbatch will fall onto the guide plate 10. The surface of the guide plate 10 has a certain slope, which allows the black masterbatch to slide down the slope into the holes opened on the guide plate 10, and then fall onto the screen 507 through the holes. At the same time, the stepper motor 4 is started by the control terminal, so that the output terminal of the stepper motor 4 drives the screw conveyor 9 to rotate. The rotation of the screw conveyor 9 can play a certain role in conveying the black masterbatch, thereby avoiding blockage when the black masterbatch falls to a certain extent. The model of the stepper motor 4 is 86BYG250-113, and the stepper motor 4 is electrically connected to the control terminal.

[0030] Working principle: Before using this screening device for black masterbatch production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, firstly, by setting up a screening device, when the black material falls onto the screen 507 through the guide plate 10, the two electric push rods 502 located above are simultaneously activated by the control terminal. This causes the output end of the electric push rods 502 to drive the connecting block 503 downwards, causing the connecting block 503 to slide on the slide rod 504. Simultaneously, the sliding of the connecting block 503 compresses the buffer spring 505, causing it to deform. The buffer spring 505 can be made of a suitable material according to actual usage, thereby extending its service life. This allows the buffer spring 505 to provide some auxiliary cushioning from the side. Simultaneously, when the connecting block 503 descends, it causes the screen 507 and baffle 508 to descend. The outer walls of the screen 507 and baffle 508 are fitted against the inner wall of the housing 2, thus preventing... To prevent the black masterbatch from falling, the upward movement of the output end of the electric push rod 502 causes the connecting block 503, screen 507, and baffle 508 to rise, thus enabling the screen 507 to reciprocate up and down, thereby screening the black masterbatch. Simultaneously, when the two upper electric push rods 502 are activated, the control terminal can also activate the two lower electric push rods 502. When the output ends of the two upper electric push rods 502 extend downwards, the output ends of the two lower electric push rods 502 are retracted. When the output ends of the two upper electric push rods 502 are retracted, the output ends of the two lower electric push rods 502 extend upwards. This allows the two upper and two lower electric push rods 502 to reciprocate up and down on two screens 507 with different aperture sizes, enabling multi-stage screening of the black masterbatch.

[0031] Secondly, by setting up a stepper motor 4, a screw conveyor 9, and a guide plate 10, after the black masterbatch is poured into the box 2 through the feed pipe 3, the black masterbatch will fall onto the guide plate 10. The surface of the guide plate 10 has a certain slope, which allows the black masterbatch to slide down the slope into the holes opened on the guide plate 10, and then fall onto the screen 507 through the holes. At the same time, the stepper motor 4 is started by the control terminal, so that the output terminal of the stepper motor 4 drives the screw conveyor 9 to rotate. The rotation of the screw conveyor 9 can play a certain role in conveying the black masterbatch, thereby avoiding blockage when the black masterbatch falls to a certain extent.
