Since bright beads are flammable and explosive, there are safety hazards when the bright beads fall layer by layer from top to bottom; and the discharge port arranged on each layer is connected to the transport belt, the discharge is not accurate, and the screening effect is not ideal; at the same time, the screening plates or screening boxes are arranged in multiple layers vertically, and it is inconvenient to disassemble and clean the screen. Utility Model Content

[0003] The main purpose of the utility model is to provide a vibrating screen of an automatic screening machine for fireworks beads, aiming to improve the screening effect of the beads and solve the problems of accurate material discharge and inconvenient screen removal and cleaning.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A vibrating screen for an automatic screening machine for fireworks beads, comprising a frame, a shell and a sieve plate, characterized in that the shell is divided into at least two cavities, a sieve plate is arranged inside each cavity to divide the cavity into an upper and lower layer, the sieve holes of the sieve plate corresponding to each cavity are different in size, and the cavity is divided into particle areas of different particle sizes, the shell is provided with a discharge port at the lower layer position corresponding to each cavity, the shell is provided with a vibration device, and the shell vibrates under the drive of the vibration device to complete the screening of the beads.

[0006] Furthermore, the particle areas in the lower layer of the cavity are independent of each other, and the inner wall of the cavity is provided with support bars for installing the sieve plate.

[0007] Furthermore, the shell is provided with a feed tray.

[0008] The feed tray is connected to the particle area with the smallest particle size, and the sieve holes of the sieve plate increase in sequence along the horizontal direction from the feed port of the vibration screen.

[0013] The beneficial effects of the utility model are:

[0014] 1. The technical solution of the utility model is different from the prior art in that the prior art screens the beads vertically from top to bottom, with the large-particle beads being screened downwards, and the top layer is the beads with the largest particle size, while the utility model screens the beads horizontally from the smallest beads in sequence, and the beads with the smallest particle size are first screened into the feeding cavity. This structure screens the beads horizontally, eliminating the potential safety hazards in the process of vertical layer-by-layer falling of the beads, and also facilitates the coordinated use of the overall structure of the fireworks beads automatic screening machine, ensuring the safety of the overall process of the fireworks beads automatic screening machine.

The bright beads move horizontally in a wave-like manner under the vibration of the shell, and fall evenly into the feeding cavity from the sieve holes with different particle sizes, which can accurately achieve the screening effect. The sieve is easy to disassemble and clean, with a simple structure and no safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 It is a bottom view of Example 1 of the automatic screening integrated machine for fireworks beads of the utility model. DETAILED DESCRIPTION

[0018] The following will be combined with the attached embodiment of the present invention 1 Figure 1 , clearly and completely describe the technical solution in Example 1 of the utility model.

[0019] Reference Figure 1The utility model discloses a vibrating screen 1 of an automatic screening machine for fireworks beads, comprising a screen plate 2 and a shell 3, wherein the shell 3 is divided into a plurality of cavities 5 by a partition plate 4, and the number of cavities can be set to 2, 3, 4, or more according to the requirements of the bright beads. In this embodiment, the number of cavities is four. The inner wall of each cavity 5 is provided with a support bar (not shown in the figure), and four screen plates 2 are respectively placed in each cavity 5 through the support bar, so as to divide the cavity 5 into two layers, the upper layer of the cavity 5 is filled with bright beads, and the sieve holes of the screen plates 2 in the four cavities have different particle sizes, and the sieve holes sequentially divide the cavity 5 into a fine particle area 51, a small particle area 52, a standard particle area 53, and a large particle area 54 from small to large, and one side of the fine particle area 51 is connected to a feed tray 6, and the feed tray 6 is arranged below the granulation tank of the automatic screening machine for fireworks beads.

[0020] The regulating door 7 is fixed at the connection between the feed tray 6 and the fine particle area 51 through the door shaft, and the regulating door 7 is connected to a swing cylinder (not shown in the figure), and the swing cylinder is electrically connected to the main controller of the fireworks and bright beads automatic screening machine. The regulating door 7 is opened and closed by the swing cylinder to control the feeding. The housing 3 is provided with a discharge port 8 at the lower layer position corresponding to each cavity 5.

[0021] Support rods are respectively arranged at the four top corners of the bottom of the housing 3 and are hinged on the frame 10 by bolts to form active points 9, and the number of active points 9 is set to 2, 3 or more. A fixed shaft 11 is arranged at the bottom of the housing 3, one end of the connecting rod 12 is connected to the fixed shaft 11, and the other end is connected to the eccentric shaft 13, the eccentric shaft 13 is fixed to the frame 10, and is connected to the driving shaft of the hydraulic motor 14, and the hydraulic motor 14 is electrically connected to the main controller of the fireworks bright beads automatic screening machine.

[0022] As a specific implementation of the movable connection between the shell 3 and the frame 10, a movable support rod and a support frame can be set on the shell 3, and various movable parts such as balls, rollers, and movable bearing seats can be set at the bottom of the shell 3 to connect with the frame 10.

[0023] After the fireworks beads automatic screening machine is started and the beads granulation process is completed, the fireworks beads enter the feed tray 6 from the discharge port of the granulation tank, and the main controller of the fireworks beads automatic screening machine starts the hydraulic motor 14. The shell 3 and the feed tray 6 vibrate in a wave-like manner under the action of the eccentric shaft 13 and the connecting rod 12. At the same time, the main controller of the fireworks beads automatic screening machine controls the swing cylinder to open the regulating door 7. The opening and closing of the regulating door 7 controls the number of beads fed from the feed tray 6 to the sieve plate 2. The beads roll from the feed tray 6 onto the sieve plate 2, and the beads pass through the fine particle area 51, small particle area 52, standard particle area 53 and large particle area 54 of the sieve plate 2 in sequence with the vibration of the shell 3.

[0024] The sieve hole particle size of the sieve plate 2 on the fine particle area 51 is the smallest, and the bright beads with a particle size less than or equal to the sieve hole particle size of the fine particle area 51 fall from the sieve hole into the lower layer of the cavity 5, and the bright beads with a particle size greater than the sieve hole particle size of the fine particle area 51 move to the small particle area 52 with the vibration of the shell 3, and so on, the bright beads of different particle sizes pass through the sieve holes on the sieve plate 2 in sequence and fall into the cavities 5 of the small particle area 52, the standard particle area 53 and the large particle area 54. Because the lower material cavity of each particle area is independently separated, the bright beads of different particle sizes fall into the lower material cavity and are output through each discharge port 8, and the bright beads of different particle sizes are transported through the barrel set below each discharge port 8.

[0025] In the present invention, the sieve plate 2 can also be set as an integral sieve plate. Correspondingly, the sieve holes of the integral sieve plate are set according to different requirements corresponding to the particle sizes of each particle zone.

[0026] In the utility model, the vibrating screen 1 may not be provided with a receiving tray. After the granulation is completed, the bright beads fall directly from the discharge port of the granulation tank onto the sieve plate 2 of the cavity, and the sieving of the bright beads is completed in sequence according to the above-mentioned sieving procedure.

For example, "connection" can be a fixed connection, a detachable connection, a movable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
