Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule processing equipment, and more specifically, to a plastic granule vibrating screening machine. Background Technology
[0002] A vibrating screen for plastic granules is a screening device specifically designed for plastic granules (such as polyethylene, polypropylene, ABS, etc.). It uses vibration to classify and screen plastic granules of different sizes, and is widely used in the raw material pretreatment stage of plastic product manufacturing (such as screening after crushing recycled materials and separating impurities from virgin materials). Its core function is to use the kinetic energy generated by vibration to make the plastic granules tossed or slide on the screen surface, achieving granule classification based on differences in screen aperture size, while simultaneously removing impurities or separating granules that meet specifications.
[0003] Existing vibrating screens are ineffective at clearing blockages in the screen plates and screening plastic particles, resulting in localized blockages in the screen holes and adhesion of plastic particles during the screening process, making effective screening impossible.
[0004] Therefore, there is an urgent need for a plastic particle vibrating screening machine that can effectively perform plastic particle screening and screen plate unclogging operations. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic particle vibration screening machine to solve the technical defects existing in the background technology.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0007] A vibrating screening machine for plastic granules includes a base plate with shock-absorbing support rods on all four sides of its upper surface. A screening frame is mounted on the upper end of each shock-absorbing support rod. A vibration motor is mounted on the lower surface of the screening frame near the left side. A feed frame is mounted on the upper left side of the screening frame. An auxiliary screening mechanism is located inside the screening frame. A first discharge frame is located on the right side of the screening frame, and a second discharge frame is located on the right side of the front surface of the screening frame. The auxiliary screening mechanism is a detachable screen plate installed inside the screening frame. The screen plate has orderly arranged screen holes on its surface and raised blocks on its upper surface, located around the screen holes. Support columns are mounted on arc plates on the front and rear surfaces of the screening frame. A movable track is provided between two support columns, and a drive slide frame is mounted on the movable track. An electric telescopic rod is mounted on the lower surface of the drive slide frame, and a protective frame is connected to the end of the electric telescopic rod. A pusher rod is located on the lower surface of the protective frame.
[0008] As a further embodiment of this utility model, the screen plate is installed in the middle of the screening frame and is flush with the first discharge frame, ensuring that larger particles that have not passed through the screen holes on the screen plate can smoothly slide into the first discharge frame under the action of vibration and push rod.
[0009] As a further embodiment of this invention, the protrusion is a cone-shaped structure that "disperses" the accumulated particles during vibration, preventing the particles from sticking together due to compression and thus preventing them from passing through the sieve holes, thereby improving screening efficiency.
[0010] As a further embodiment of this invention, both the electric telescopic rod and the drive slide frame are connected to an external power source to ensure automated operation and improve screening efficiency.
[0011] As a further embodiment of this utility model, the driving slide frame is configured for linear return motion.
[0012] As a further embodiment of this utility model, the protective frame is a frame with an opening on its lower surface. The opening design does not affect the contact between the push rod and the screen plate, and can also protect the connection between the electric telescopic rod and the push rod.
[0013] As a further embodiment of this utility model, the push rod is arranged correspondingly to the sieve holes, and the distance between adjacent push rods is the distance between two sieve holes. The push rod is made of antistatic material, which can prevent particles from sticking together and ensure the pushing and screening effect.
[0014] As a further embodiment of this invention, the push rod is made of glass fiber reinforced nylon. Beneficial effects
[0015] Compared with a traditional plastic granule vibrating screening machine, this utility model has the following advantages:
[0016] This utility model, through its auxiliary screening mechanism, can actively clean the screen plate by cooperating with the lifting and reciprocating motion of the protective frame during or after the vibrating screening process, thus preventing blockage. At the same time, the protrusions on the surface of the screen plate can ensure that the plastic particles that are stuck together are broken up during the vibrating screening process.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figures 1-4 As shown, this utility model provides a technical solution for a vibrating screening machine for plastic granules:
[0026] As shown in the figure, a vibrating screening machine for plastic granules includes a base plate 1. Shock-absorbing support rods 2 are arranged on the four sides of the upper surface of the base plate 1. A screening frame 3 is installed on the upper end of the shock-absorbing support rods 2. A vibrating motor 4 is arranged on the lower surface of the screening frame 3 near the left side. A feed frame 5 is arranged on the upper left side of the screening frame 3. An auxiliary screening mechanism 6 is arranged inside the screening frame 3. A first discharge frame 7 is arranged on the right side of the screening frame 3, and a second discharge frame 8 is arranged on the right side of the front surface of the screening frame 3. The auxiliary screening mechanism 6 is detachably installed inside the screening frame 3. The sieve plate 61 has orderly arranged sieve holes 62 on its surface. The upper surface of the sieve plate 61 is provided with protrusions 63, which are located around the sieve holes 62. The front and rear surfaces of the screening frame 3 are provided with arc plates on which support columns 64 are installed. A movable track 65 is provided between the two support columns 64. A drive slide frame 66 is installed on the movable track 65. An electric telescopic rod 67 is provided on the lower surface of the drive slide frame 66. A protective frame 68 is connected to the end of the electric telescopic rod 67. A push rod 69 is provided on the lower surface of the protective frame 68.
[0027] The screen plate 61 is installed in the middle of the screening frame 3 and is flush with the first discharge frame 7, ensuring that larger particles that have not passed through the screen holes on the screen plate can slide smoothly into the first discharge frame under the action of vibration and push rod.
[0028] The protrusion 63 is a cone-shaped structure that "breaks up" the accumulated particles during vibration, preventing the particles from sticking together due to compression and thus preventing them from passing through the sieve holes, thereby improving screening efficiency.
[0029] Both the electric telescopic rod 67 and the drive slide frame 66 are connected to an external power source to ensure automated operation and improve screening efficiency.
[0030] The drive slider 66 is set to return in a straight line.
[0031] The protective frame 68 is a frame with an opening on the lower surface. The opening design does not affect the contact between the push rod and the screen plate, and can protect the connection between the electric telescopic rod and the push rod.
[0032] The push rod 69 is set in a corresponding manner to the sieve hole 62. The distance between adjacent push rods 69 is the distance between two sieve holes 62. The push rod 69 is made of antistatic material, which can prevent particles from sticking together and ensure the pushing and screening effect.
[0033] The push rod 69 is made of glass fiber reinforced nylon.
[0034] The specific implementation principle is as follows: Plastic granules enter the surface of the screen plate 61 through the feed frame 5. The entire equipment realizes the vibration screening operation of the plastic granules under the start of the vibration motor 4. During the vibration screening process, some adhesive plastic granules will be broken up by the protrusions 63 to ensure effective screening of plastic granules. At the same time, when it is necessary to clear the blockage of the screen hole 62, the operation of the drive slide frame 66 and the electric telescopic rod 67 can be used simultaneously or afterward to make the protective frame 68 fall to a distance that matches the screen plate 61. The linear back-and-forth movement of the protective frame 68 makes the push rod 69 rub against the screen hole 62 to ensure clearing of blockage.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
