Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle screening, in particular to an improved plastic particle grading and screening device. Background Art

[0002] Plastic is a polymer compound that is polymerized by addition polymerization or condensation polymerization using monomers as raw materials. Plastic granules are semi-finished products of the plastic molding industry. They are composed of synthetic resins, fillers, plasticizers, lubricants, etc., and can freely change their composition and shape. Plastic granules can be further processed into related plastic products. In industrial production, the processed raw materials are extruded through an extruder to become strips, which are melted by heating to form a melt. Then, a granulator is used to extrude the molten material and cut it into granules, which are cooled to form the required plastic granules.

[0003] After searching, it is found that the utility model with publication number CN217531479U provides a plastic particle grading and screening device, including a base, a rotatably connected mounting frame is arranged on the base, and also includes a screening drum assembly, the screening drum assembly is rotatably arranged on the mounting frame, a driving member is also fixedly connected to the mounting frame, the driving member is used to drive the screening drum assembly to rotate, and a control unit is also arranged between the mounting frame and the base, and the control unit is used to drive the mounting frame to rotate; the screening drum assembly includes a cylinder connected to the output end of the driving member, a sealing cover is detachably connected to a side of the cylinder away from the driving member, a pipe fitting distributed along the axial direction of the cylinder and connected with the sleeve is arranged in the cylinder, a leakage hole is opened on the side wall of the pipe fitting, the leakage hole on the inner pipe fitting has a diameter larger than the leakage hole on the outer pipe fitting, and an operation cover door is opened on the sealing cover corresponding to each pipe fitting. Although the device is capable of better preserving all plastic particles, avoiding leakage and saving production costs; however, when the plastic particles are screened for too long, dust may be contaminated inside.

[0023] Example: See Figure 1 — Figure 4 The utility model provides a technical solution: an improved plastic particle grading and screening device, comprising a screening box 1, a feeding hopper 2 is arranged on the top of the screening box 1, support plates 3 are arranged on both sides of the top of the screening box 1, and electric telescopic rods 4 are arranged on one side of the two support plates 3, two storage slots 7 are equidistantly arranged on the left side of the screening box 1, slide slots 8 are arranged on both sides of the two storage slots 7, the inner cavities of the two storage slots 7 are respectively provided with a first screening net 9 and a second screening net 10, sliders 11 are fixedly installed on both sides of the first screening net 9 and the second screening net 10, handles 12 are fixedly installed on the left sides of the first screening net 9 and the second screening net 10, a first discharging trough 13 and a second discharging trough 20 are equidistantly arranged on the right side of the screening box 1, a fixed plate 15 is arranged at the bottom of the screening box 1, and hydraulic telescopic rods 16 are arranged around the bottom of the fixed plate 15.

[0024] Among them, a stop plate 5 is provided on one side of the output end of the two electric telescopic rods 4, and a connecting groove 6 is penetrated and opened on one side of the feed hopper 2.

[0025] In the present embodiment, the two abutment plates 5 are driven by the output ends of the two electric telescopic rods 4 to move in relative directions in the inner cavity of the feed hopper 2 through the two connecting grooves 6, so as to adjust the distance between the two abutment plates 5. Since the two abutment plates 5 are located in the inner cavity of the feed hopper 2, when the distance between the two abutment plates 5 is adjusted, the size of the inner cavity of the feed hopper 2 can be adjusted synchronously, thereby preventing the feed hopper 2 from being blocked due to the one-time entry when feeding plastic particles, thereby causing unnecessary influence on normal work.

[0026] The first screening net 9 and the second screening net 10 are both slidably installed in the inner cavity of the screening box 1 through the slider 11 in the slide groove 8 .

[0027] In this embodiment, by pulling the two handles 12 outward, the first screening net 9 and the second screening net 10 can be driven to slide synchronously in the slide groove 8 through the slider 11, and are taken out from the inner cavities of the two storage slots 7 in the device body 1 respectively, so that it is convenient for users to clean and replace the first screening net 9 and the second screening net 10, thereby bringing convenience to users.

[0028] The first collecting box 14 and the second collecting box 19 are equidistantly arranged on the right side of the screening box 1 , and are closely fitted to the right sides of the first discharging trough 13 and the second discharging trough 20 , respectively.

[0029] In this embodiment, the first collecting box 14 and the second collecting box 19 can collect the plastic particles after classification and screening, and when they are tightly fitted with the first discharging trough 13 and the second discharging trough 20, the undesirable phenomenon of spilling when the plastic particles are collected after screening can be prevented.

[0030] The mesh diameter of the first screening net 9 is larger than the mesh diameter of the second screening net 10 .

[0031] The first screening net 9 and the second screening net 10 are both arranged in the inner cavity of the screening box 1 at an angle of 45° in the same direction.

[0032] In this embodiment, the first screening net 9 and the second screening net 10 can perform two different-sized and efficient graded screening operations on the plastic particles, and setting the first screening net 9 and the second screening net 10 at a 45° angle can enable the plastic particles to be rolled from top to bottom and screened quickly, thereby improving the effect of plastic particle screening.

[0033] The bottom of the hydraulic telescopic rod 16 is fixedly mounted with an anti-slip seat 17 , and the bottom is frosted, and the top of the anti-slip seat 17 is provided with a spring 18 .

[0034] In this embodiment, the screening box 1 is driven to move up and down through the output ends of the four hydraulic telescopic rods 16 through the fixed plate 15. When the screening box 1 moves up and down, the corresponding four springs 18 are squeezed and reset, so that the screening box 1 can move up and down to drive the plastic particles on the first screening net 9 and the second screening net 10 to shake synchronously, thereby preventing the first screening net 9 and the second screening box 10 from causing mesh blockage when screening the plastic particles, resulting in unnecessary impact on the normal screening work.

[0035] Working principle: first, the output ends of the two electric telescopic rods 4 drive the two abutment plates 5 to move in relative directions in the inner cavity of the feed hopper 2 through the two connecting grooves 6, and adjust the distance between the two abutment plates 5. Since the two abutment plates 5 are located in the inner cavity of the feed hopper 2, when the distance between the two abutment plates 5 is adjusted, the size of the inner cavity of the feed hopper 2 can be adjusted synchronously. After the adjustment is completed, the plastic particles are put into the screening box 1 through the feed hopper 2. After entering, the plastic particles can be screened twice with different sizes and high efficiency through the first screening net 9 and the second screening net 10. The first screening net 9 and the second screening net 10 are set at a 45° angle to enable the plastic particles to be rolled and screened quickly from top to bottom, thereby improving the effect of screening the plastic particles. During screening, the screening box 1 is driven up and down through the output ends of the four hydraulic telescopic rods 16 through the fixed plate 15. The screening box 1 is moved up and down. When moving downward, the corresponding four springs 18 are squeezed and reset, so that the screening box 1 can be moved up and down, driving the plastic particles on the first screening net 9 and the second screening net 10 to shake synchronously, thereby preventing the first screening net 9 and the second screening box 10 from being blocked when screening the plastic particles. After the screening is completed, the plastic particles are discharged into the first collecting box 14 and the second collecting box 19 for storage through the first discharging trough 13 and the second discharging trough 20 respectively. When the first screening net 9 and the second screening net 10 need to be cleaned, the two handles 12 can be pulled outward to drive the first screening net 9 and the second screening net 10 to slide synchronously in the slide groove 8 through the slider 11, and are taken out from the inner cavities of the two storage slots 7 in the equipment body 1 respectively, so that it is convenient for users to clean and replace the first screening net 9 and the second screening net 10, thereby bringing convenience to users.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
