Description

Technical Field

[0001] The utility model relates to the field of plastic particle production equipment, in particular to a plastic particle screening machine. Background Art

[0002] Plastic particles are the common name for plastic particles, which are the raw materials for storing, transporting and processing plastics in the form of semi-finished products.

[0003] The main purpose of screening plastic particles is to control the size and shape of the particles to meet the needs of different products. Through screening, impurities can be removed, the uniformity and stability of the particles can be improved, and thus the quality and performance of plastic products can be improved. In addition, screening can also help adjust the particle size distribution of the particles, so that the plastic products have better processing performance and molding effect. Therefore, screening is very important for the production and processing of plastic particles.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0023] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0024] See also Figures 1 to 4 In this embodiment, a plastic particle screening machine is provided, including a frame 1, wherein a multi-layer sieve plate 3 is slidably connected to the inside of the frame 1, and the sieve plate 3 is placed obliquely, and a lower hopper 2 is installed above the sieve plate 3 at one end of the frame 1, and a discharge chute 4 is installed at the front side of one end of the frame 1;

[0025] A separation mechanism 6 is installed inside the frame 1 above the lower hopper 2 . The separation mechanism 6 includes a movable comb plate 65 for separating plastic particles. The lower end of the movable comb plate 65 is close to the top of the screen plate 3 .

[0026] When in use, the bottom sieve plate 3 cannot pass through plastic particles. The number of discharge troughs 4 is determined according to the number of layers of the sieve plate 3. The frame is provided with an outlet at the lower end of the sieve plate 3 connected to the discharge trough 4. The plastic particles are released through the lower hopper 2 and fall onto the top of the sieve plate 3. In the process of sliding down on the sieve plate 3, the plastic particles pass through the multiple layers of sieve plates 3 for screening. In the process of sliding down, the plastic particles can be combed out by the movable combing plate 65, thereby preventing the clumped plastic particles from being unable to be screened out on the sieve plate 3.

[0027] In further embodiments, see Figure 2 A valve plate 21 is inserted into the lower part of the lower hopper 2, and one end of the valve plate 21 is bent and tilted downward. When in use, the depth of the valve plate 21 inserted into the lower hopper 2 is used to adjust the speed of the lower hopper 2 to discharge materials. By rotating a screw rod connected to one side of the lower hopper 2, the end of the valve plate 21 that is exposed to the outside is screwed through by the screw rod. The user can drive the valve plate 21 to move by rotating the screw rod, which can stabilize the position of the valve plate 21 in the lower hopper 2 so that it will not slip out easily, and it is easier to grasp when adjusting.

[0028] In further embodiments, see Figure 3 The frame 1 is slidably connected with a mounting frame 31, and a plurality of limit frames 32 are vertically fixedly connected to both sides of the frame 1. The limit frames 32 pass through the mounting frame 31, and the limit frames 32 are slidably connected with the mounting frame 31, and the sieve plate 3 is installed inside the mounting frame 31. The sieve plate 3 can be installed inside the frame 1 through the mounting frame 32, and the sieve plate 3 can be kept moving up and down by the limit frames 32.

[0029] In further embodiments, see Figure 3 A driving device 5 for lifting the mounting frame 31 is installed inside the frame 1 below the mounting frame 31. The driving device 5 includes a driving motor. An eccentric wheel is connected to one end of the driving motor. The eccentric wheel fits the bottom of the mounting frame 31. A spring is connected between the mounting frame 31 and the bottom of the frame 1. The mounting frame 31 is supported by the spring. The eccentric wheel can be driven to rotate by starting the driving motor. The rotation of the eccentric wheel lifts the mounting frame 31 up and down, thereby vibrating the plastic particles, so that the plastic particles are fully in contact with the screen plate 3.

[0030] In further embodiments, see Figure 4 The separation mechanism 6 includes a fixed frame 61 and a plurality of sliding frames 63. The fixed frame 61 is fixedly mounted above the frame 1, and the sliding frames 63 are fixedly mounted on the mounting frame 31. The sliding frames 63 are provided with transverse grooves inside. A fixed combing plate 64 is fixedly mounted on one side of the transverse groove. A movable combing plate 65 is slidably connected to one side of the fixed combing plate 64 inside the transverse groove. A connecting rod 66 is connected between the movable combing plates 65. A connecting plate 62 is sleeved on the outer side of the connecting rod 66. The upper end of the connecting plate 62 is rotatably connected to the fixed frame 61. The movable combing plate 65 slides inside the transverse groove. When the sliding frame 63 rises with the mounting frame 31, the sliding frame 63 rises close to the fixed frame 61. The distance between the sliding frame 63 and the fixed frame 61 becomes smaller, and the connecting plate 62 rotates accordingly. The lower end of the connecting plate 62 pushes the movable combing plate 65 to slide inside the transverse groove. The movable combing plate 65 is staggered with the fixed combing plate 64 to comb and disperse the agglomerated plastics passing through.

[0031] In a further embodiment, the fixed comb plate 64 and the movable comb plate 65 are provided with a plurality of comb teeth at the lower ends, and the fixed comb plate 64 and the movable comb plate 65 are both made of elastic material. When the plurality of comb teeth are interlaced with each other, the plastic particles will not be damaged.

[0032] In further embodiments, see Figure 1 The discharging trough 4 is tilted at one end, and the opening of the discharging trough 4 faces different directions. The tilting of one end of the discharging trough 4 makes it easier for the material to slide out, and the openings face different directions, so that the user can place the collection boxes of the collected materials on both sides without interfering with each other.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
