A color master batch screening device

Abstract

This utility model discloses a color masterbatch screening device, including a shell, a screening frame, a screening plate, a drive assembly, a transmission assembly, a transmission mechanism, and a baffle. The color masterbatch to be screened is placed in the placement chamber. The drive assembly drives the transmission assembly and the transmission mechanism to operate. The transmission assembly drives the baffle to rotate. The rotation of the baffle intermittently blocks the bottom of the feed pipe, causing the raw material to fall intermittently into the screening frame, thereby achieving continuous small-volume screening of the raw material. The transmission mechanism drives the slide plate to reciprocate and vibrate. During the reciprocating sliding of the slide plate, the screening frame on one side of the slide plate reciprocates and vibrates. The reciprocating vibration of the screening frame causes the falling raw material to vibrate continuously, so that color masterbatch of different sizes is screened on different levels of the screening plate. During the reciprocating vibration of the slide plate, the pull rope, in cooperation with the elastic component, causes the color masterbatch on one side of the screening plate to shake continuously, thereby improving the screening efficiency.

Description

Technical Field

[0001] This utility model relates to a screening device, specifically a masterbatch screening device. Background Technology

[0002] Masterbatch, also known as colorant or colorant powder, is a new type of colorant specifically for polymer materials, also called pigment preparation. It is mainly used in plastics. Masterbatch consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate obtained by uniformly loading an excessive amount of pigment into resin, and can be called a pigment concentrate. Therefore, its coloring power is higher than that of the pigment itself. Due to the small size and large quantity of masterbatch, it is difficult to manually screen out the substandard small masterbatch. Directly screening a large number of masterbatch at once can easily lead to accumulation, thus affecting the screening efficiency. Therefore, a masterbatch screening device needs to be designed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a masterbatch screening device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A masterbatch screening device includes a housing with a placement chamber and a screening chamber. A groove is formed on the side wall of the screening chamber, and a sliding plate is slidably mounted in the groove. A sliding plate has a groove on its side, and a slider is slidably mounted in the groove. An elastic component is provided on one side of the slider, and the end of the elastic component away from the slider is connected to the side wall of the groove. A guide wheel is installed on the side wall of the screening chamber, and a pull rope is installed on the top wall of the screening chamber. The other end of the pull rope is connected to the slider and wound around the guide wheel. A screening frame is installed on the slider, and several screening plates are arranged in the screening frame. Each screening plate has screening holes, and the size of the screening holes on the screening plates decreases from top to bottom. A feed pipe is provided at the bottom of the placement chamber, with the end of the feed pipe away from the placement chamber located on the upper side of the screening frame. A baffle is provided on one side of the bottom of the feed pipe. A drive assembly is installed on the housing, and a transmission assembly and a transmission mechanism are installed in the screening chamber. One end of the transmission assembly is connected to the drive assembly, and the other end is connected to the baffle. One end of the transmission mechanism is connected to the drive assembly, and the other end is connected to the sliding plate.

[0006] As a further embodiment of this utility model: the driving assembly includes a driving component, which is mounted on the housing, and a driving shaft is mounted on the output end of the driving component, with the end of the driving shaft away from the driving component extending into the screening chamber.

[0007] As a further embodiment of this utility model: the transmission assembly includes a driven shaft, one end of which is rotatably connected to the top wall of the screening chamber, and the other end is connected to a baffle. A connecting unit is installed on the drive shaft, and the end of the connecting unit away from the drive shaft is connected to the driven shaft.

[0008] As a further embodiment of this utility model: the transmission mechanism includes a rotating shaft, one end of which is rotatably connected to the side wall of the screening chamber, and the other end is connected to a cam. The cam is located on one side of the slide plate, and an elastic element is installed at the bottom of the slide plate. The end of the elastic element away from the slide plate is connected to the bottom wall of the trough. A connecting mechanism is installed on the drive shaft, and the end of the connecting mechanism away from the drive shaft is connected to the rotating shaft.

[0009] As a further embodiment of this invention, the elastic component is a spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the masterbatch to be screened is placed in the placement chamber. The driving component drives the connected driving shaft to rotate. The rotation of the driving shaft drives the driven shaft to rotate through the connecting unit. The rotation of the driven shaft drives the connected baffle to rotate. The rotation of the baffle can intermittently block the bottom of the feed pipe. This intermittent blocking of the feed pipe allows the raw material to fall intermittently into the screening frame, thereby achieving continuous small-volume screening of the raw material and improving the screening quality. The rotation of the driving shaft drives the connected rotating shaft to rotate through the connecting mechanism, and the rotation of the rotating shaft drives the connected... The connected cam rotates, and through its interaction with the elastic element, it drives the connected slide plate to slide back and forth. During the back-and-forth sliding of the slide plate, the screening frame on one side of the slide block vibrates back and forth. The back-and-forth vibration of the screening frame causes the falling raw material to vibrate continuously, thereby achieving the screening of color masterbatch. This allows color masterbatch of different sizes to be screened on different levels of the screening plate. During the back-and-forth vibration of the slide plate, the pull rope, through its interaction with the elastic element, drives the slide block to slide back and forth in the chute. The back-and-forth sliding of the slide block causes the screening frame to continuously shake the color masterbatch on one side of the screening plate, facilitating the screening of the color masterbatch and improving screening efficiency.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-3 As an embodiment of this utility model, a masterbatch screening device includes a housing 1, on which a placement cavity 2 and a screening cavity 3 are formed. A groove 6 is formed on the side wall of the screening cavity 3, and a sliding plate 4 is slidably installed in the groove 6. A sliding block 5 is slidably installed in the groove 6, and an elastic component 8 is provided on one side of the sliding block 5. The end of the elastic component 8 away from the sliding block 5 is connected to the side wall of the groove 6. A guide wheel is installed on the side wall of the screening cavity 3, and a pull rope 9 is installed on the top wall of the screening cavity 3. The other end of the pull rope 9 is connected to the sliding block 5, and the pull rope 9 is wound around the guide wheel. A guide wheel is installed on the sliding block 5. A screening frame 11 is provided, and several screening plates 12 are provided in the screening frame 11. Each screening plate 12 has a screen hole, and the size of the screen hole on the screening plate 12 decreases from top to bottom. A feeding pipe 21 is provided at the bottom of the placement cavity 2. The end of the feeding pipe 21 away from the placement cavity 2 is located on the upper side of the screening frame 11, and a baffle 20 is provided on one side of the bottom of the feeding pipe 21. A driving assembly is installed on the housing 1. A transmission assembly and a transmission mechanism are installed in the screening cavity. One end of the transmission assembly is connected to the driving assembly and the other end is connected to the baffle 20. One end of the transmission mechanism is connected to the driving assembly and the other end is connected to the slide plate 4.

[0017] In this embodiment, when the device is in use, the masterbatch to be screened is placed in the placement chamber 2. The drive component drives the connected transmission component and transmission mechanism to operate. The transmission component drives the connected baffle 20 to rotate. The rotation of the baffle 20 can intermittently block the bottom of the feed pipe 21. The intermittent blocking of the feed pipe 21 allows the raw material to fall intermittently into the screening frame 11, thereby achieving continuous small-volume screening of the raw material and improving the screening quality. The transmission mechanism drives the connected slide plate 4 to reciprocate and vibrate. During the sliding process, the screening frame 11 on one side of the slider 5 reciprocates and vibrates. The reciprocating vibration of the screening frame 11 causes the falling raw material to vibrate continuously, thereby achieving the screening of color masterbatch. This allows color masterbatch of different sizes to be screened on different levels of the screening plate 12. During the reciprocating vibration of the slide plate 4, the pull rope 9, in cooperation with the elastic component 8, drives the slider 5 to slide back and forth in the chute 6. The reciprocating sliding of the slider 5 causes the screening frame 11 to drive the color masterbatch on one side of the screening plate 12 to vibrate continuously, which facilitates the screening of color masterbatch and improves the screening efficiency.

[0018] Furthermore, the elastic component 8 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0019] As an embodiment of the present invention, the driving assembly includes a driving component 22, which is mounted on the housing 1. A driving shaft 17 is mounted on the output end of the driving component 22, and the end of the driving shaft 17 away from the driving component 22 extends into the screening chamber 3.

[0020] In this embodiment, the drive component 22 drives the drive shaft 17 connected to it to rotate. The rotation of the drive shaft 17 drives the transmission assembly and transmission mechanism connected to it to operate. The transmission assembly drives the baffle 20 connected to it to rotate. The rotation of the baffle 20 can intermittently block the bottom of the feed pipe 21. The intermittent blocking of the feed pipe 21 allows the raw material to fall intermittently into the screening frame 11, thereby achieving continuous small-volume screening of the raw material and improving the screening quality. The transmission mechanism drives the slide plate 4 connected to it to reciprocate and vibrate. During the sliding process, the screening frame 11 on one side of the slider 5 reciprocates and vibrates. The reciprocating vibration of the screening frame 11 causes the falling raw material to vibrate continuously, thereby achieving the screening of color masterbatch. This allows color masterbatch of different sizes to be screened on different levels of the screening plate 12. During the reciprocating vibration of the slide plate 4, the pull rope 9, in cooperation with the elastic component 8, drives the slider 5 to slide back and forth in the chute 6. The reciprocating sliding of the slider 5 causes the screening frame 11 to drive the color masterbatch on one side of the screening plate 12 to vibrate continuously, which facilitates the screening of color masterbatch and improves the screening efficiency.

[0021] Furthermore, the driving component 22 can be a stepper motor or a servo motor, etc., which will not be described in detail here.

[0022] As an embodiment of the present invention, the transmission assembly includes a driven shaft 19, one end of which is rotatably connected to the top wall of the screening chamber 3, and the other end is connected to the baffle 20. A connecting unit 18 is installed on the drive shaft 17, and the end of the connecting unit 18 away from the drive shaft 17 is connected to the driven shaft 19.

[0023] In this embodiment, the driving component 22 drives the driving shaft 17 connected to it to rotate. The rotation of the driving shaft 17 drives the driven shaft 19 to rotate through the connecting unit 18. The rotation of the driven shaft 19 drives the baffle 20 connected to it to rotate. The rotation of the baffle 20 can intermittently block the bottom of the feed pipe 21. The intermittent blocking of the feed pipe 21 allows the raw material to fall intermittently into the screening frame 11, thereby achieving continuous small-volume screening of the raw material and improving the screening quality.

[0024] Furthermore, the connecting unit 18 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0025] As an embodiment of this utility model, the transmission mechanism includes a rotating shaft 14, one end of which is rotatably connected to the side wall of the screening chamber 3, and the other end is connected to a cam 16. The cam 16 is disposed on one side of the slide plate 4. An elastic element 13 is installed at the bottom of the slide plate 4. The end of the elastic element 13 away from the slide plate 4 is connected to the bottom wall of the slide groove 6. A connecting mechanism 15 is installed on the drive shaft 17. The end of the connecting mechanism 15 away from the drive shaft 17 is connected to the rotating shaft 14.

[0026] In this embodiment, the drive shaft 17 rotates, which in turn drives the connected rotating shaft 14 to rotate via the connecting mechanism 15. The rotating shaft 14 rotates, which in turn drives the connected cam 16 to rotate. The rotating cam 16 rotates, which in turn drives the connected slide plate 4 to slide back and forth via the cooperation of the elastic element 13. During the back and forth sliding of the slide plate 4, the screening frame 11 on one side of the slider 5 vibrates back and forth. The back and forth vibration of the screening frame 11 causes the falling raw material to vibrate continuously, thereby enabling the screening of color masterbatch. This allows color masterbatch of different sizes to be screened on different levels of the screening plate 12. During the back and forth vibration of the slide plate 4, the pull rope 9 drives the slider 5 to slide back and forth in the chute 6 via the cooperation of the elastic element 8. The back and forth sliding of the slider 5 causes the screening frame 11 to drive the color masterbatch on one side of the screening plate 12 to vibrate continuously, which facilitates the screening of color masterbatch and improves the screening efficiency.

[0027] Furthermore, the elastic element 13 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0028] Furthermore, the connecting mechanism 15 can be a gear set or a worm gear and worm wheel combination, which will not be described in detail here.

[0029] The working principle of this utility model is as follows: When the device is in use, the masterbatch to be screened is placed in the placement chamber 2. The driving component 22 drives the driving shaft 17 connected to it to rotate. The rotation of the driving shaft 17 drives the driven shaft 19 to rotate through the connecting unit 18. The rotation of the driven shaft 19 drives the baffle 20 connected to it to rotate. The rotation of the baffle 20 can intermittently block the bottom of the feed pipe 21. The intermittent blocking of the feed pipe 21 allows the raw material to fall intermittently into the screening frame 11, thereby achieving continuous small-volume screening of the raw material and improving the screening quality. The rotation of the driving shaft 17 drives the rotating shaft 14 connected to it to rotate through the connecting mechanism 15. The rotation of the rotating shaft 14 drives the rotating shaft 14 connected to it to rotate. The cam 16 rotates, and the rotation of the cam 16, through its cooperation with the elastic element 13, drives the slide plate 4 connected to it to slide back and forth. During the back and forth sliding of the slide plate 4, the screening frame 11 on one side of the slider 5 is driven to shake back and forth. The back and forth shaking of the screening frame 11 causes the falling raw material to shake continuously, thereby realizing the screening of color masterbatch. This allows color masterbatch of different sizes to be screened on different levels of screening plates 12. During the back and forth shaking of the slide plate 4, the pull rope 9, through its cooperation with the elastic element 8, drives the slider 5 to slide back and forth in the chute 6. The back and forth sliding of the slider 5 causes the screening frame 11 to drive the color masterbatch on one side of the screening plate 12 to shake continuously, which facilitates the screening of color masterbatch and improves the screening efficiency.
