[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic particle vibrating screen. Background Art

[0002] Plastic processing refers to the process of transforming plastic raw materials into plastic products with specific shapes, properties and uses through a series of physical or chemical changes.

[0003] Plastic granule vibrating screen is a screening device used in the plastic processing process, which is specially used to screen and grade plastic granules. Its main function is to separate plastic granules of different sizes or specifications, remove impurities, and improve the purity and uniformity of the material.

[0004] The disadvantage of the existing technical solution is that the size of the sieve holes on the plastic particle vibrating screen is fixed, so a sieve plate of corresponding size needs to be installed on the plastic particle vibrating screen according to demand. If the demand for the required size of the plastic particles changes, the corresponding sieve plate needs to be replaced according to demand, and the replacement and installation steps of the sieve plate are relatively cumbersome, thereby reducing the screening efficiency. Utility Model Content

If the required size of the plastic particles changes, the corresponding sieve plate needs to be replaced according to the demand, thereby reducing the screening efficiency.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] A plastic particle vibrating screen comprises a base, a screen box is arranged on the base, a first screen plate is fixedly connected to the inside of the screen box, a material receiving cavity is arranged at the bottom of the first screen plate, the device also comprises a filter assembly for cooperating with the first screen plate and an adjustment assembly for adjusting the filter assembly, the filter assembly comprises a second screen plate, the screen holes on the first screen plate cooperate with the screen holes at relative positions on the second screen plate, the adjustment assembly is arranged on one side of the screen box and cooperates with the second screen plate.

[0008] As a further solution of the utility model: a mounting opening matched with the second screen plate is opened on one side of the screen box, and a reserved opening matched with the second screen plate is opened on the other side of the screen box.

[0009] As a further solution of the utility model: a connecting block is fixedly connected to one side of the screen box, the adjusting assembly includes a threaded rod threadedly connected to the connecting block, the threaded rod is rotatably connected to a wedge block at one end close to the second screen plate, the second screen plate is provided with an adjusting port that matches the wedge block, and the threaded rod is fixedly connected to a rotating assembly away from the second screen plate.

[0011] As a further solution of the utility model: the side of the wedge block is provided with an adjustment range that matches the second sieve plate.

[0012] As a further solution of the utility model: the elastic component is fixedly connected with a fixing block near one end of the pull plate, the pull plate is provided with a limiting opening, and the fixing block is rotatably connected with a limiting knob matching the limiting opening.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model adjusts the relative position of the first sieve plate and the second sieve plate so that the sieve holes on the first sieve plate and the second sieve plate are misaligned, so that the sieve holes on the two groups of sieve plates overlap and block each other to form overlapping through holes. When screening plastic particles, the plastic particles will enter the material receiving chamber through the overlapping through holes, so as to achieve the screening of plastic particles. By controlling the misalignment degree between the first sieve plate and the second sieve plate, the size of the overlapping through holes can be adjusted, and then the diameter range of the plastic particles passing through the overlapping through holes can be controlled, which is more convenient to use.

[0015] 2. The utility model provides an adjustment range on one side of the wedge block. When the rotating assembly is rotated to adjust the position of the wedge block, the wedge block will move up and down along the adjustment port. The more the wedge block enters the adjustment port, the greater the misalignment between the first sieve plate and the second sieve plate. In the process of adjusting the second sieve plate, the misalignment between the first sieve plate and the second sieve plate can be accurately adjusted by comparing the adjustment range on the side of the wedge block with the relative position of the adjustment port, thereby controlling the diameter range of the plastic particles passing through the overlapping through holes.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, a plastic particle vibrating screen comprises a base 1, which is connected to a screen box 2 through a spring assembly, a vibration motor is fixedly connected to the screen box 2 for realizing the vibration of the screen box 2, a first screen plate 4 is fixedly connected inside the screen box 2, a material receiving cavity 3 is arranged at the bottom of the first screen plate 4, the device further comprises a filter assembly 5 for cooperating with the first screen plate 4 and an adjustment assembly 6 for adjusting the filter assembly 5, the filter assembly 5 comprises a second screen plate 501, the screen holes on the first screen plate 4 cooperate with the screen holes at the relative position on the second screen plate 501, the adjustment assembly 6 is arranged on one side of the screen box 2, And cooperate with the second sieve plate 501; adjust the relative position of the first sieve plate 4 and the second sieve plate 501 through the adjustment component 6, so that the sieve holes on the first sieve plate 4 and the second sieve plate 501 are misaligned, so that the sieve holes on the two groups of sieve plates overlap and block each other to form overlapping through holes. When screening plastic particles, the plastic particles will enter the material receiving chamber 3 through the overlapping through holes, thereby realizing the screening of plastic particles. The degree of misalignment between the first sieve plate 4 and the second sieve plate 501 is controlled by the adjustment component 6, thereby adjusting the size of the overlapping through holes, and then the diameter range of the plastic particles passing through the overlapping through holes can be controlled.

[0024] In some specific embodiments, in order to facilitate the adjustment of the position of the second sieve plate 501, a mounting opening 12 matching the second sieve plate 501 is opened on one side of the sieve box 2, and a reserved opening 11 matching the second sieve plate 501 is opened on the other side of the sieve box 2; the mounting opening 12 and the reserved opening 11 are both slidably connected to the second sieve plate 501, and when the adjustment component 6 adjusts the position of the second sieve plate 501, the second sieve plate 501 will slide along the mounting opening 12 and the reserved opening 11, thereby realizing the adjustment of the position of the second sieve plate 501.

[0025] In some specific embodiments, in order to achieve adjustment of the second sieve plate 501, a connecting block 6 is fixedly connected to one side of the screen box 2, and the adjustment component 6 includes a threaded rod 702 threadedly connected to the connecting block 6, and the threaded rod 702 is rotatably connected to a wedge block 703 at one end close to the second sieve plate 501, and an adjustment port 503 matching the wedge block 703 is opened on the second sieve plate 501, and the threaded rod 702 is fixedly connected to a rotating component 701 at one end away from the second sieve plate 501, and the rotating component 701 can be a knob; in the process of adjusting the second sieve plate 501, it is necessary to rotate the rotating component 701 to drive the threaded rod 702 to rotate, so that the threaded rod 702 moves downward along the connecting block 6, thereby pushing the wedge block 703 to move downward, and the inclined surface of the wedge block 703 enters and squeezes the adjustment port 503, so that the second sieve plate 501 is displaced to one side as a whole, thereby achieving adjustment of the position of the second sieve plate 501.

[0026] In some specific embodiments, in order to achieve automatic resetting of the second screen plate 501, a pull plate 502 is fixedly connected to one end of the second screen plate 501, and an elastic component 8 is fixedly connected to the side of the screen box 2 close to the pull plate 502, and the elastic component 8 includes a spring. The elastic component 8 is cooperatively connected to the pull plate 502 at one end away from the screen box 2; after the wedge block 703 moves downward, the threaded rod 702 can be driven to rotate in the opposite direction by rotating the rotating component 701, and the threaded rod 702 and the wedge block 703 are displaced upward under the action of the connecting block 6, and the second screen plate 501 will continue to squeeze the inclined surface of the wedge block 703 under the action of the elastic component 8, thereby achieving the resetting of the second screen plate 501.

[0027] In some specific implementation schemes, in order to facilitate the staff to control the degree of misalignment between the first sieve plate 4 and the second sieve plate 501, an adjustment range that matches the second sieve plate 501 is set on the side of the wedge block 703, and the reading on the adjustment range corresponds to the relative misalignment degree of the first sieve plate 4 and the second sieve plate 501; when the rotating component 701 is rotated to adjust the position of the wedge block 703, the wedge block 703 will move up and down along the adjustment port 503, and the more the wedge block 703 enters the adjustment port 503, the greater the misalignment degree between the first sieve plate 4 and the second sieve plate 501. In the process of adjusting the second sieve plate 501, the degree of misalignment between the first sieve plate 4 and the second sieve plate 501 can be accurately adjusted by comparing the relative position of the adjustment range and the adjustment port 503, so that the diameter range of the plastic particles passing through the overlapping through holes can be controlled.

[0028] In some specific implementation schemes, in order to facilitate the replacement and maintenance of the second screen plate 501, the elastic component 8 is fixedly connected to a fixed block 10 near one end of the pull plate 502, and a limit opening 504 is opened on the pull plate 502. A limit knob 9 matching the limit opening 504 is rotatably connected to the fixed block 10, and the limit opening 504 is the same size as the limit knob 9; the limit knob 9 is rotated to adapt the limit knob 9 to the limit opening 504, and the pull plate 502 is pulled. The limit knob 9 passes through the pull plate 502 along the limit opening 504, and the pull plate 502 drives the second screen plate 501 to move along the installation opening 12, thereby realizing the disassembly and separation of the filter component 5 and the screen box 2, thereby facilitating the maintenance and replacement of the filter component 5, and the disassembly method can be referred to for processing during installation.

[0029] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0030] Before pouring in the plastic particles, it is necessary to first observe the adjustment range on the side of the wedge block 703 to determine whether the degree of misalignment between the first sieve plate 4 and the second sieve plate 501 is appropriate, so as to ensure that the diameter of the plastic particles passing through the first sieve plate 4 and the second sieve plate 501 is within the specified range. If it is found after observing the adjustment range that the degree of misalignment between the first sieve plate 4 and the second sieve plate 501 is too small, it is necessary to rotate the rotating assembly 701 to drive the threaded rod 702 to rotate, so that the threaded rod 702 moves downward along the connecting block 6, thereby pushing the wedge block 703 downward, and the inclined surface of the wedge block 703 enters and squeezes the adjustment port 503, so that the second sieve plate 501 is displaced to one side as a whole, thereby realizing the adjustment of the position of the second sieve plate 501. If the misalignment between the first sieve plate 4 and the second sieve plate 501 is too large after observing the adjustment range, the threaded rod 702 can be driven to rotate in the opposite direction by rotating the rotating assembly 701, and the threaded rod 702 and the wedge block 703 are displaced upward under the action of the connecting block 6, and the second sieve plate 501 will continue to squeeze the inclined surface of the wedge block 703 under the action of the elastic assembly 8, thereby achieving the adjustment of the misalignment between the first sieve plate 4 and the second sieve plate 501. When it is necessary to disassemble the second sieve plate 501, the limit knob 9 is rotated so that the limit knob 9 is adapted to the limit opening 504, and the pull plate 502 is pulled. The limit knob 9 passes through the pull plate 502 along the limit opening 504, and the pull plate 502 drives the second sieve plate 501 to move along the installation opening 12, thereby achieving the disassembly and separation of the filter assembly 5 and the screen box 2, thereby facilitating the maintenance and replacement of the filter assembly 5. The disassembly method can be referred to for processing during installation.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
