Description

Technical Field

[0001] This application relates to the field of ink production equipment technology, and in particular to an ink powder vibration screening device. Background Technology

[0002] In the ink production process, the quality of the ink powder plays a crucial role in the final ink product's quality. Typically, ink powder exhibits uneven particle size after preparation, and the inclusion of powder that does not meet particle size requirements in the finished product can lead to deterioration in the ink's flowability, tinting strength, and printability. Therefore, it is necessary to screen the ink powder to remove excessively large or small particles to ensure product quality.

[0003] Existing powder screening devices suffer from problems such as low screening efficiency, easy screen clogging, and poor adaptability to different particle size requirements when screening ink powder. For example, in traditional fixed screen screening devices, powder relies solely on natural falling or simple shaking to pass through the screen, which easily leads to localized powder accumulation and clogging, affecting the continuity of screening. Moreover, for situations requiring frequent switching of different screen specifications to screen different batches of ink powder, the operation is cumbersome, time-consuming, and not conducive to efficient production. Therefore, a vibrating screening device for ink powder is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening device for ink powder to solve the problems of low screening efficiency, easy clogging of screens, and poor adaptability to screening different particle sizes in existing ink powder screening devices, thereby improving the quality and efficiency of ink powder screening.

[0005] The technical solution of the vibratory screening device for ink powder provided in this application is as follows:

[0006] A vibrating screening device for ink powder includes a screening box. One end of the screening box has a feed inlet, and the other end has a waste outlet. Multiple guide wheels are installed on the upper and lower inner walls of the screening box. Multiple screen cylinders are rotatably connected between the multiple guide wheels. Multiple filter holes are provided on the outer wall of the multiple screen cylinders. The filter holes gradually increase in size from the feed inlet to the waste outlet. A spiral plate is fixedly connected to the inner wall of the multiple screen cylinders. Multiple material-pushing plates are also fixedly connected to the inner wall of the multiple screen cylinders. The multiple material-pushing plates penetrate the spiral plate.

[0007] A brush plate is installed on the inner wall of the top middle section of the screening box. The brush plate is always in contact with the top surface of the multi-stage screen cylinder through an elastic connection mechanism.

[0008] A vibration motor is mounted on one side of the outer wall of the screening box via a mounting bracket, and a base frame is mounted on the bottom outer wall of the screening box. Multiple top ends of the base frame are fixedly connected to the bottom outer wall of the screening box with buffer springs.

[0009] Preferably, the bottom outer wall of the screening box is provided with multiple discharge ports, and the multiple discharge ports correspond sequentially to the filter holes of different inner diameters on the outer wall of the multi-stage screen cylinder.

[0010] Preferably, the elastic connection mechanism includes two sliding rods slidably connected to the top outer wall of the screening box. The bottom ends of the two sliding rods penetrate the screening box and are fixedly connected to the top outer walls of both ends of the brush plate. A telescopic spring is sleeved on the outer wall of the sliding rod. One end of the telescopic spring is fixedly connected to the outer wall of the brush plate, and the other end is fixedly connected to the top inner wall of the screening box.

[0011] Preferably, the top ends of the two slide bars are fixedly connected to a connecting plate, which corresponds to the brush plate and is located on the outer wall of the top middle section of the screening box.

[0012] Preferably, the screening box is rotatably connected to a drive wheel via a rotating shaft on the outer wall of the inlet. The drive wheel is in contact with one end edge of the multi-stage screen cylinder. The outlet is fixedly mounted with a servo motor via a bracket on the outer wall of the inlet. The output shaft of the servo motor is fixedly connected to the outer wall of the drive wheel's axis.

[0013] Preferably, shock-absorbing pads are fixedly connected to multiple bottom ends of the base frame.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The vibrating motor drives the screening box to vibrate, allowing the ink powder to jump and tumble fully within the multi-stage screen cylinder. The servo motor drives the drive wheel to rotate, which in turn drives the multi-stage screen cylinder to rotate. When the spiral plate and the material-pushing plate inside the multi-stage screen cylinder rotate, they can push the powder and tumble it at a uniform speed, accelerating the process of the powder passing through the screen. Compared with the traditional screening method that relies on natural falling or simple shaking, this greatly improves the screening speed and effectively shortens the screening time of a single batch of ink powder, thereby improving the overall production efficiency.

[0016] 2. The brush plate setting can clean the surface of the multi-stage screen cylinder in real time, avoiding the blockage of the multi-stage screen cylinder caused by the stickiness or accumulation of ink powder, ensuring the continuity of screening work, reducing the time loss of frequent machine stoppages for cleaning due to blockage of multi-stage screen cylinders, and further ensuring efficient and stable screening operation.

[0017] 3. The buffer springs and shock-absorbing pads configured at the top and bottom of the base frame can effectively absorb the impact force generated during the operation of the vibrating motor and the vibration of the screening box, reduce the vibration transmitted to the ground, reduce the noise caused by vibration, and also help protect the work site and surrounding equipment where the device is located, creating a good working environment.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a vibratory screening device for ink powder. (Refer to...) Figure 1-4 A vibrating screening device for ink powder includes a screening box 1. One end of the screening box 1 is provided with a feed inlet 2 and the other end is provided with a waste outlet 3. Multiple guide wheels 5 are installed on the inner walls of the upper and lower sides of the screening box 1. Multiple screen cylinders 4 are tumblingly connected between the multiple guide wheels 5. Multiple filter holes are provided on the outer wall of the multiple screen cylinders 4. The filter holes gradually increase in size from the feed inlet 2 to the waste outlet 3. A spiral plate 10 is fixedly connected to the inner wall of the multiple screen cylinders 4. Multiple material pushing plates 11 are also fixedly connected to the inner wall of the multiple screen cylinders 4. The multiple material pushing plates 11 penetrate the spiral plate 10.

[0025] A brush plate 14 is installed on the inner wall of the top middle section of the screening box 1. The brush plate 14 is always in contact with the top surface of the multi-stage screen cylinder 4 through an elastic connection mechanism.

[0026] A vibration motor 18 is mounted on one side of the outer wall of the screening box 1 via a mounting bracket. A base frame 12 is mounted on the bottom outer wall of the screening box 1. Multiple top ends of the base frame 12 are fixedly connected to the bottom outer wall of the screening box 1 with buffer springs 19.

[0027] The bottom outer wall of the screening box 1 is provided with multiple discharge ports 9, which correspond in turn to the filter holes of different inner diameters on the outer wall of the multi-stage screen cylinder 4.

[0028] The elastic connection mechanism includes two sliding rods 15 that are slidably connected to the top outer wall of the screening box 1. The bottom ends of the two sliding rods 15 pass through the screening box 1 and are fixedly connected to the top outer walls of both ends of the brush plate 14. A telescopic spring 16 is sleeved on the outer wall of the sliding rod 15. One end of the telescopic spring 16 is fixedly connected to the outer wall of the brush plate 14, and the other end is fixedly connected to the top inner wall of the screening box 1.

[0029] The top ends of the two slide bars 15 are fixedly connected to a connecting plate 17, which corresponds to the brush plate 14 and is located on the outer wall of the top middle section of the screening box 1.

[0030] The screening box 1 is located on the outer wall of the feed inlet 2 and is rotatably connected to the drive wheel 6 via a rotating shaft. The drive wheel 6 is in contact with one end edge of the multi-stage screen cylinder 4. The discharge port 9 is located on the outer wall of the feed inlet 2 and is fixedly installed with a servo motor 8 via a bracket 7. The output shaft of the servo motor 8 is fixedly connected to the outer wall of the shaft of the drive wheel 6.

[0031] Multiple bottom ends of the base frame 12 are fixedly connected with shock-absorbing pads 13.

[0032] The implementation principle of the ink powder vibration screening device in this application embodiment is as follows: During use, the vibration frequency and amplitude of the vibration motor 18 are adjusted to parameters suitable for the current ink powder screening through an external control circuit. Then, the ink powder to be screened is poured into the multi-stage screen cylinder 4 from the feed inlet 2. Under the vibration of the multi-stage screen cylinder 4, the ink powder jumps and rolls inside the multi-stage screen cylinder 4. At this time, the servo motor 8 is started, and the output shaft of the servo motor 8 drives the drive wheel 6 to rotate. The drive wheel 6 rotates due to friction with the edge of the multi-stage screen cylinder 4. The multi-stage screen cylinder 4 is driven to roll on multiple guide wheels 5. When the multi-stage screen cylinder 4 rotates, it will drive the spiral plate 10 and multiple material feeding plates 11 to rotate. When the spiral plate 10 rotates, it will convey the powder at a uniform speed toward the waste port 3. When the multiple material feeding plates 11 rotate, they can continuously feed the tumbling powder, so that the powder can be evenly spread in the multi-stage screen cylinder 4. At this time, when the particle size is smaller than the filter hole on the corresponding multi-stage screen cylinder 4, the powder will pass through the multi-stage screen cylinder 4 and be discharged from the corresponding discharge port 9, falling into the external collection box (not shown in the figure) for collection.

[0033] Meanwhile, as the multi-stage screen cylinder 4 rotates, its top end continuously contacts the brush plate 14. Since the brush plate 14 is installed in the screening box 1 through an elastic connection mechanism, the elastic force generated by the telescopic spring 16 in the elastic connection mechanism will continuously squeeze the brush plate 14, causing multiple brushes at the bottom of the brush plate 14 to abut against the surface of the multi-stage screen cylinder 4. The brushes will penetrate deep into the filter holes. As the multi-stage screen cylinder 4 rotates, the brush plate 14 can push the powder particles stuck in the filter holes into the multi-stage screen cylinder 4, thereby avoiding clogging of the filter holes on the multi-stage screen cylinder 4. When the screening operation is completed, the vibration motor 18 and the servo motor 8 are turned off, and the screened ink powder of different particle size ranges is taken out, completing the entire screening process.
