Description

Technical Field

[0001] The utility model belongs to the technical field of masterbatch production, and in particular relates to a particle screening device for masterbatch production. Background Art

[0002] The full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant for polymer materials, also known as pigment preparation. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment to the resin. It can be called pigment concentrate, so its coloring power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration, which is mainly used in plastics. In the production process of masterbatch, the bar masterbatch needs to be screened by the particle size through a screening machine after being pelletized by the pelletizer, so that the masterbatch with the same particle size can be packaged and stored.

[0003] The Chinese utility model patent with the announcement number CN218948162U discloses a particle screening device for masterbatch production, including a screening box, a box door is provided on the front of the screening box, and a grading screening device is provided inside the screening box, and the grading screening device includes a placement cross plate, a connecting bearing seat, a connecting rotating rod, a first screening plate, a right end placement plate, an L-shaped connecting frame, a bottom end connecting block, a sliding rod, a connecting spring, a second screening plate, a third screening plate and a vibration motor. The utility model, by providing a grading screening device, can screen the masterbatch into four levels of different particle sizes according to demand, and cooperate with the structures such as the connecting spring and the vibration motor to increase the shaking of the screening plate, can ensure the speed and better ensure the quality of screening, and the masterbatch to be screened is not easy to be missed.

[0004] However, the above utility model still has some shortcomings:

[0005] During the use of the above-mentioned utility model, the masterbatch to be screened is put into the screening box through the feed pipe so as to grade and screen the masterbatch according to the particle size. The entrance of the feed pipe is at a certain distance from the first screening plate, which leads to the problem that some of the masterbatch will bounce up and leave directly from the first discharge trough when contacting the first screening plate, resulting in incomplete screening. In addition, there is a distance between every two layers of screening plates, and there is also the problem that the masterbatch of the upper layer falls on the screening plate of the lower layer after screening and bounces directly to the discharge trough to leave, which also leads to incomplete screening.

A plurality of screening holes 10 are provided on each screening plate 9, and the aperture of each layer of screening holes 10 gradually decreases from top to bottom. A baffle 11 is fixed between every two screening plates 9 and at the bottom of the upper screening plate 9.

The discharge component 18 can gradually put the masterbatch to be screened at the discharge trough 16 onto the screening plate 9, so as to avoid the masterbatch being dumped on the screening plate 9 all at once, causing the masterbatch to bounce up and resulting in incomplete screening;

[0033] When the masterbatch to be screened passes through the upper screening plate 9 and falls onto the lower screening plate 9, the falling and bouncing masterbatch will be stopped by the baffle 11, so that it rolls through the channel between the baffle 11 and the lower screening plate 9, thereby preventing the masterbatch from bouncing off the screening plate 9 during the screening process, resulting in incomplete screening.

[0034] Furthermore, the discharge assembly 18 includes a baffle plate 182, a movable hole 188 is provided at the entrance of the uppermost screen plate 9 and at the top of the screen box 1, an installation box 181 is installed around the movable hole 188, and a movable hole 187 is provided directly above the movable hole 188 and at the top of the installation box 181, and the baffle plate 182 is movably inserted into the movable hole 187 and the movable hole 188.

[0036] Furthermore, baffle plate 2 182 is fixedly connected to a plurality of track teeth 183 along the vertical direction on the side wall away from the discharge box 14, and each track tooth 183 is meshed with a gear 184, and the gears 184 are sleeved and installed on the side wall of a connecting rod 185, one end of the connecting rod 185 is rotatably installed on the side wall of the installation box 181, and the other end of the connecting rod 185 is connected to the output shaft end of a rotating motor 186, and the rotating motor 186 is installed on the inner wall of the installation box 181.

[0037] Specifically, the rotating motor 186 controls the connecting rod 185 to drive the gear 184 to rotate, so that the tooth 183 drives the baffle 2 182 to move in the vertical direction; it should be noted that the baffle 2 182 moves upward for a distance, stops for a period of time, and then moves upward to avoid a large amount of masterbatch to be screened from rushing into the screening plate 9 at once, resulting in incomplete screening.

[0038] Furthermore, a discharge trough 16 is provided at the entrance of the uppermost screening plate 9 and at the left side wall of the screening box 1 , and a second inclined block 17 is fixedly connected to the inner wall of the discharge box 14 and the discharge trough 16 , and the inclined block 17 is inclined toward the position of the discharge trough 16 .

[0039] Specifically, the masterbatch to be screened poured from the feed hopper 15 enters the discharge box 14, and moves to the position of the discharge trough 16 under the action of the inclined block 17, so as to enter the position of the screening plate 9 for screening.

[0041] Specifically, the masterbatch passing through the bottom screen plate 9 falls on the inclined block 12 for storage. When the operator opens the receiving door 13, the masterbatch at the bottom of the screening box 1 moves to the receiving door 13 under the action of the inclined block 12 and leaves the screening box 1 to complete the collection of the masterbatch at the bottom layer.

[0042] Furthermore, the vibration assembly 4 includes a vibration motor 41, which is installed in the vibration box 3. The output end of the vibration motor 41 is connected to a connecting plate 42. The top of the connecting plate 42 is connected to a mounting plate 44 through a telescopic cylinder 43. A spring 45 is sleeved on the outer wall of the telescopic cylinder 43. The side of the screening plate 9 with a higher inclined height is fixedly connected to the mounting plate 44.

[0043] Specifically, a vibration hole 19 corresponding to the vibration box 3 is opened on the left side wall of the screening box 1, and the connection between the screening plate 9 and the mounting plate 44 is arranged in the vibration hole 19, so that the mounting plate 44 drives the screening plate 9 to vibrate;

[0044] The thick end of the telescopic cylinder 43 is fixedly connected to the top of the connecting plate 42, and the thin end is fixedly connected to the bottom of the mounting plate 44; when the vibration motor 41 is working, it drives the connecting plate 42 to vibrate synchronously, so that the spring 45 and the telescopic cylinder 43 drive the mounting plate 44 and the screening plate 9 to shake in the vertical direction to screen the masterbatch.

[0045] Working principle and use process of the utility model: After the utility model is installed, the masterbatch to be screened is poured from the feed hopper 15 into the discharge box 14, and the masterbatch to be screened moves to the position of the discharge trough 16 under the action of the inclined block 17 and is blocked by the baffle 182 at the entrance of the uppermost screening plate 9;

[0046] The vibration motor 41 drives the connecting plate 42 to vibrate synchronously, so that the spring 45 and the telescopic cylinder 43 drive the mounting plate 44 and the screening plate 9 to shake in the vertical direction;

[0047] During the operation of the vibration motor 41, the rotating motor 186 controls the connecting rod 185 to drive the gear 184 to rotate, so that the tooth 183 drives the baffle plate 182 to move upward. During this process, the baffle plate 182 moves upward for a distance, stops for a period of time, and then moves upward, so that the masterbatch to be screened slowly rolls over the screening plate 9;

[0048] When the masterbatch to be screened passes through the upper screening plate 9 and falls onto the next screening plate 9, the masterbatch that falls and bounces up will be stopped by the baffle 11, so that the masterbatch rolls through the channel between the baffle 11 and the next screening plate 9, and enters the receiving box 6 from the discharge plate 8, completing the collection of the screened masterbatch;

[0049] The masterbatch passing through the bottom sieve plate 9 will fall on the inclined block 12 for storage, and the operator can open the receiving door 13 to collect it.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
