Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a screening machine with an auxiliary breaking up structure. Background Art

[0002] The screening machine is a screening machine that utilizes the relative movement between bulk materials and the screen surface to allow some particles to pass through the screen holes and classify the bulk materials into different grades according to particle size. In the production process of milk powder, a screening machine is needed, and the milk powder is screened and graded by the screening machine to ensure the uniformity and quality of the milk powder.

[0003] At present, when the existing screening machine is in use, the milk powder is fed into the screening box through the feed port, and the particles in the milk powder are separated according to size by means of vibration screening. However, when the milk powder clumps, the agglomerated milk powder particles are large and cannot pass through the screen smoothly, so they will be screened out, requiring staff to perform re-selection operations, making the screening process of the milk powder more cumbersome. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a screening machine with an auxiliary breaking up structure to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a screening machine with an auxiliary breaking-up structure, comprising a screening box and a vibrating screen, wherein the interior of the screening box is provided with an upper and a lower layer of vibrating screens, the interior of the screening box is located above the vibrating screen and is welded with an outer frame, the interior of the screening box is provided with a breaking-up mechanism, the breaking-up mechanism comprises a driving motor and a supporting shaft, the supporting shaft is rotatably arranged on the inner side of the outer frame, the lower end of the supporting shaft is welded with a rotating plate, the interior of the screening box is located between the vibrating screen and the rotating plate and is provided with a breaking-up frame movably connected thereto, and a linkage plate is movably connected between the breaking-up frame and the rotating plate.

[0006] Preferably, a driving motor is installed on one side of the screening box, the output end of the driving motor is connected to a rotating shaft via a coupling, and the rotating shaft is drivingly connected to a supporting shaft via a pulley set.

[0007] Preferably, the disassembling frame and the rotating plate form a linkage structure through a linkage plate, and two groups of the disassembling frames are symmetrically arranged about the central axis of the supporting shaft.

[0008] Preferably, a limit rod is welded and connected inside the screening box, and limit holes are symmetrically provided inside the debonding frame, and the debonding frame and the screening box form a sliding structure through the limit holes and the limit rod.

[0009] Preferably, a material discharge port is opened inside one side of the screening box, a support plate is provided on one side of the screening box, and a material receiving frame is movably connected to the top end of the support plate.

[0010] Preferably, a guide groove is provided at the top end of the support plate, and a guide plate is welded to the bottom end of the material receiving frame, and the material receiving frame and the support plate form a clamping structure through the guide plate and the guide groove.

[0011] Preferably, a limiting mechanism is provided at the front end of the support plate, and the limiting mechanism consists of a limiting frame, a supporting spring and a limiting plate. The limiting frame is welded and connected to the front end of the support plate, and the limiting plate is slidably connected to the inside of the limiting frame. A supporting spring is welded and connected between the limiting plate and the limiting frame, and a slope is provided at the front end of the limiting plate.

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

[0013] 1. When the milk powder is agglomerated, the existing screening machine cannot pass through the screen smoothly, so it will be screened out, and the staff needs to perform the selection operation again, which makes the screening process of the milk powder more complicated. The utility model is provided with a breaking mechanism to drive the motor to work. The output end of the driving motor drives the rotating shaft, the supporting shaft, and the rotating plate to reciprocate forward and reverse under the action of the pulley group. Since the linkage plate, the breaking frame, and the rotating plate are all rotatably connected by the pin shaft, the breaking frame slides back and forth, so that the agglomerated milk powder large particles can be impacted and broken up by the breaking frame, and then the milk powder can be quickly screened, making the screening process of the milk powder simpler;

[0014] 2. Existing screening machines generally collect the materials after screening through a collecting frame, but it is generally placed directly, which makes it easy for it to deviate when it is accidentally hit, thereby easily causing material to be scattered. The utility model is provided with a guide plate, a guide groove and a limit mechanism. Since the limit plate and the limit frame are elastically connected by a supporting spring, and one end of the limit plate is provided with an inclined surface, when collecting materials, the collecting frame is pushed from front to back, so that the guide plate is stuck in the guide groove, and the limit plate abuts against the front end of the collecting frame, thereby limiting the collecting frame and preventing it from deviating when it is accidentally hit, so as to prevent material from being scattered.
