Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing equipment, in particular to a vibrating screen used for masterbatch processing and preparation. Background Art

[0002] Color concentrate is a mixture of resin and a large amount of pigment or dye with high color concentration. Color concentrate is a kind of aggregate made by uniformly loading an extraordinary amount of pigment or dye in resin. When processing, a small amount of color concentrate is mixed with uncolored resin to achieve a colored resin or product with the designed pigment concentration.

[0003] The Chinese patent (authorization announcement number: CN 210546228 U, authorization announcement date: 2020.05.19) proposes a vibrating screen for masterbatch processing and preparation. The patent can accurately screen out masterbatch particles with a size larger than the first sieve hole size and smaller than the second sieve hole size, ensuring that the finished masterbatch particles have extremely high size uniformity, meeting the needs of high-standard users.

[0004] The patented screen is set horizontally, and the masterbatch stays on the screen for too long, affecting the efficiency of masterbatch screening. The masterbatch is prone to stacking on the screen, and the patented device does not have an intermittent feeding device for the masterbatch. If too much material is put into the patented device at one time, it is also easy to cause the masterbatch to stay on the screen for a long time, thereby affecting the screening effect of the masterbatch. In order to avoid the influence of the horizontal setting of the screen and facilitate intermittent feeding of masterbatch to avoid affecting the screening effect of the masterbatch, we propose a vibrating screen for masterbatch processing and preparation.

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 The utility model provides a technical solution: a vibrating screen for masterbatch processing and preparation, comprising a frame 1, a primary screening frame 5 is installed on the frame 1, a secondary screening frame 6 is fixedly connected to the bottom of the primary screening frame 5, a discharging frame 7 is fixedly connected to the bottom of the secondary screening frame 6, a primary screening mesh plate 21 is fixedly installed on the primary screening frame 5, a secondary screening mesh plate 22 is fixedly installed on the secondary screening frame 6, a motion component for driving the secondary screening frame 6 to reciprocate left and right is installed on the left side of the frame 1, and an intermittent discharging component is installed above the frame 1.

[0023] When in use, the masterbatch is intermittently fed through the intermittent discharging component, thereby avoiding the screening effect being affected by the excessive amount of masterbatch fed at one time. Afterwards, the moving component drives the one-time screening frame 6, the secondary screening frame 6 and the discharging frame 7 to reciprocate left and right. The one-time screening frame 5, the secondary screening frame 6 and the discharging frame 7 are all tilted, again avoiding the horizontal setting of the screen and affecting the screening effect.

[0024] The motion component includes a driving motor 3, which is fixedly mounted on the frame 1. A reducer is fixedly mounted on the output end of the driving motor 3, and a driving pulley 16 is fixedly connected to the output end of the reducer. A driving rod 14 is rotatably mounted on the left side of the upper end of the frame 1 through a bearing. A driven pulley 15 is fixedly sleeved on the outer surface of the driving rod 14, and a transmission belt 17 is tensioned and sleeved between the driven pulley 15 and the driving pulley 16. A cam 13 is fixedly connected to the front end of the driving rod 14, and a transmission plate 12 is hingedly mounted between the cam 13 and the secondary screening frame 6. Two sets of guide plates 8 are fixedly mounted on the frame 1, and multiple sets of rollers 9 are in rolling contact on the guide plates 8, and the rollers 9 are fixedly connected to the bottom of the discharge frame 7.

[0025] When the motion component is used, the driving motor 3 drives the active pulley 16 to rotate, and the active pulley 16 drives the driving rod 14 to rotate through the transmission belt 17. When the driving rod 14 rotates, it will drive the cam 13 to rotate. When the cam 13 rotates, it will cooperate with the transmission plate 12 to pull the screening frame to reciprocate left and right, so that the masterbatch vibrates on the screen plate.

[0026] The intermittent discharging component includes a feeding hopper 4, the bottom of which is integrally connected to a cylinder shell 10, the bottom of which is integrally connected to a discharging shell 11, a discharging roller 23 is rotatably installed inside the cylinder shell 10, a material port 24 is provided on the discharging shell 11, the discharging shell 11 is located above the primary screening frame 5, and a transmission mechanism is connected between the discharging roller 23 and the driving rod 14.

[0027] The transmission mechanism includes a reduction gear 20, which is fixedly connected to the end of the rotating shaft of the unloading roller 23. A matching gear 19 is rotatably installed on the frame 1 through the transmission shaft. The matching gear 19 is meshed with the reduction gear 20. A driven sprocket is fixedly connected to the end of the transmission shaft, and a driving sprocket is fixedly connected to the rear end of the driving rod 14. A transmission chain 18 is tensioned and sleeved between the driving sprocket and the driven sprocket.

[0028] The driving rod 14 rotates to drive the matching gear 19 to rotate through the transmission chain 18. When the matching gear 19 rotates, it will drive the reduction gear 20 to rotate. Under the action of the reduction gear 20 and the reducer, the unloading roller 23 will rotate slowly. A group of material ports 24 are opened on the unloading roller 23, and then the intermittent unloading of the masterbatch is realized under the slow rotation of the unloading roller 23, so as to avoid the one-time feeding amount being too large and affecting the screening effect of the masterbatch.

[0029] A plurality of sets of universal wheels 2 are fixedly mounted on the bottom of the frame 1 to improve the maneuverability of the device.

[0030] Working principle: When in use, the masterbatch to be screened is put into the feeding hopper 4, and then the driving motor 3 is started. When the driving motor 3 is working, it will drive the matching gear 19 to rotate through the transmission chain 18. When the matching gear 19 rotates, it will drive the reduction gear 20 to rotate. Under the action of the reduction gear 20 and the reducer, the unloading roller 23 will rotate slowly. A group of material ports 24 are opened on the unloading roller 23, and then the intermittent unloading of the masterbatch is realized under the slow rotation of the unloading roller 23, so as to avoid the one-time feeding amount being too large and affecting the screening effect of the masterbatch. When the driving rod 14 rotates, it will drive the cam 13 to rotate. When the cam 13 rotates, the transmission plate 12 will pull the screening frame to move back and forth, so that the masterbatch will vibrate on the screen plate, so as to realize the screening of the masterbatch. The device intermittently feeds materials through an intermittent discharging component, thereby avoiding the influence of screening effect due to excessive one-time feeding amount of masterbatch, and then the moving component drives the one-time screening frame 6, the secondary screening frame 6 and the discharging frame 7 to reciprocate left and right, and the one-time screening frame 5, the secondary screening frame 6 and the discharging frame 7 are all inclined, again avoiding the influence of screening effect due to the horizontal setting of the screen.
