[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen with an anti-deviating structure. Background Art

[0002] Lactose powder is a food raw material, mainly used as an adsorption and dispersant for powdered food pigments to reduce pigment concentration, facilitate use and reduce discoloration during storage. Lactose is one of the main nutrients for children's growth and development. Another function is to promote children's absorption of calcium during calcium metabolism. During the production process, it needs to be screened using a vibrating screen to remove unqualified materials or impurities.

[0003] At present, the existing vibrating screen is generally composed of a bracket, a screening box, a screen plate, a vibration motor, a feed port and a discharge port. When working, the material is sent into the screening box through the feed port, and the material is screened through the cooperation of the screen plate and the vibration motor. The screened material is discharged through the discharge port. When adding materials, it is easy to cause too much material to be concentrated in a certain area, which makes it easy to cause a large force deviation of the material, resulting in torsional vibration of the vibrating screen. At this time, the material speeds at different positions on the screen surface are different, and the material will deviate, spin and be retained, thereby affecting the screening efficiency. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a vibrating screen with an anti-deviating structure to solve the technical problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a vibrating screen with an anti-deviating structure, comprising a vibrating screen body, the vibrating screen body comprising a screening box, a screening plate, a bracket and a vibration motor, the screening plate being arranged inside the screening box, a vibration motor being installed at the bottom end of the screening box, and the bracket being symmetrically arranged at both ends of the screening box;

[0006] An anti-deviation mechanism extending to the outside is arranged inside the screening box above the screening plate, and the anti-deviation mechanism is composed of a driving motor, a supporting frame, a supporting shaft, a pulley set, a rotating plate, a linkage plate and a pushing frame.

[0007] Preferably, the support frame is welded to the top end of one side of the screening box, the drive motor is installed at the bottom end of the support frame, and the inner side of the support frame is rotatably connected to a support shaft extending to the inside of the screening box through a bearing.

[0008] Preferably, the outer surface of the support shaft and the outer surface of the output end of the drive motor are sleeved with a pulley group, one end of the support shaft is welded to a rotating plate, a pushing rack is provided inside the screening box above the screen plate, and a linkage plate is rotatably connected between the pushing rack and the rotating plate.

[0009] Preferably, the pushing frame is symmetrically provided with limiting holes inside, the screening box is symmetrically welded with limiting rods penetrating the limiting holes inside, and the pushing frame and the screening box form a sliding structure through the limiting rods and the limiting holes.

[0010] Preferably, a connecting mechanism extending to the interior of the screen plate is provided inside one side of the screening box, and the connecting mechanism consists of a connecting groove, a connecting plate, a return spring and a push-pull plate.

[0011] Preferably, a connecting groove is provided on one side of the bottom end of the screen plate, a connecting plate is slidably connected to the inside of one side of the screen box, a return spring is welded between the connecting plate and the screen box, a push-pull plate extending to the outside of the screen box is welded to one side of the connecting plate, and a support block forming a snap-fit ​​structure with the screen plate is welded to the inside of the screen box.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. When feeding, the existing vibrating screen is prone to excessive concentration of materials in a certain area, which will cause the materials to deviate, spin and stay, thereby affecting the screening efficiency. The utility model is provided with an anti-deviation mechanism. When the driving motor is working, the output end of the driving motor drives the support shaft and the rotating plate to reciprocate positive and negative deflection under the action of the pulley group. Since the linkage plate is rotatably connected with the rotating plate and the pushing frame, and the pushing frame is slidably connected with the screening box, the pushing frame can move in the horizontal direction, so that the materials can be evenly spread on the screen plate, avoiding excessive concentration of materials in a certain area, thereby preventing deviation and ensuring the screening efficiency of the vibrating screen;

[0014] 2. The existing vibrating screen installs the sieve plate by screws, which makes it inconvenient to clean the sieve plate later. The utility model is provided with a connecting mechanism. Since the sieve plate and the screening box are connected through the connecting plate and the connecting groove under the action of the reset spring, the connecting plate can be separated from the connecting groove by pushing the push-pull plate downward. At this time, the sieve plate can be pulled outward to separate it from the screening box, thereby facilitating the cleaning of the sieve plate. BRIEF DESCRIPTION OF THE DRAWINGS

The material is fed into the screening box 101, so that the screening operation of the material can be realized through the cooperation of the screen plate 102 and the vibration motor 104.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4It can be known that a connecting mechanism 3 extending to the inside of the sieve plate 102 is provided inside one side of the screening box 101, and the connecting mechanism 3 is composed of a connecting groove 301, a connecting plate 302, a return spring 303 and a push-pull plate 304. A connecting groove 301 is provided on one side of the bottom end of the sieve plate 102, and a connecting plate 302 is slidably connected to the inside of one side of the screening box 101, and a return spring 303 is welded between the connecting plate 302 and the screening box 101, and a push-pull plate 304 extending to the outside of the screening box 101 is welded to one side of the connecting plate 302, and a supporting block 6 forming a snap-fit ​​structure with the sieve plate 102 is welded inside the screening box 101, and an inclined surface is provided at one end of the connecting plate 302, and the sieve plate 102 and the screening box 101 form a snap-fit ​​structure through the connecting groove 301 and the connecting plate 302;

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that in the process of inserting the sieve plate 102 into the screening box 101, the connecting plate 302 will be stuck in the connecting groove 301 under the action of the reset spring 303, thereby realizing the installation of the sieve plate 102. When cleaning is needed, the connecting plate 302 can be disengaged from the connecting groove 301 by pushing the push-pull plate 304 downward. At this time, the sieve plate 102 can be pulled outward to separate it from the screening box 101, thereby facilitating the cleaning of the sieve plate 102.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be seen that the interior of the screening box 101 is located above the sieve plate 102 and is provided with an anti-deviating mechanism 2 extending to the outside, the anti-deviating mechanism 2 is composed of a driving motor 201, a support frame 202, a support shaft 203, a pulley group 204, a rotating plate 205, a linkage plate 206 and a pushing frame 207, the support frame 202 is welded and connected to the top of one side of the screening box 101, the driving motor 201 is installed at the bottom end of the support frame 202, the inner side of the support frame 202 is rotatably connected with the support shaft 203 extending to the inside of the screening box 101 through a bearing, the outer surface of the support shaft 203 and the outer surface of the output end of the driving motor 201 are sleeved with a pulley group 204, one end of the support shaft 203 is welded and connected with a rotating plate 205, the interior of the screening box 101 is located above the sieve plate 102 and is provided with a pushing frame 207, and a linkage plate 206 is rotatably connected between the pushing frame 207 and the rotating plate 205;
