Description
Technical Field
The utility model relates to a letter sorting equipment field, concretely relates to screening mechanism in advance.
Background
In the production process of chili products such as chili sauce, chopped chili and the like, the first step is to clean and sort the chili, and remove the damaged chili which is damaged by insects and the like. The hot pepper that has the problem is chosen to present letter sorting mode mostly for arranging the hot pepper in the conveyer belt of slowing down the operation, observes by the manual work. However, the angle of the peppers placed on the conveyor belt is disordered, the peppers need to be observed for a longer time during sorting, the error rate is high, and the product quality and the production efficiency are affected.
SUMMERY OF THE UTILITY MODEL
For solving the technical problem that the hot pepper letter sorting mode of prior art takes time, the error rate is high, the utility model provides a sieve mechanism in advance of solving above-mentioned problem.
A pre-screening mechanism comprises a cylindrical shell which is communicated in the vertical direction, wherein multiple layers of screens are sequentially arranged in the shell from top to bottom, each screen is a strip-shaped screen formed by parallel arrangement of a plurality of rod bodies, the rod bodies of different screens are also parallel to each other, the gaps of the screens are gradually reduced from top to bottom, and the average diameter of each screen is 1.1-1.3 times that of a batch of peppers at 2 times or more; and the outer wall of the shell is also provided with a vibration motor.
In a preferred embodiment of the pre-screening mechanism provided in the present invention, the position near the top and bottom of the housing is further provided with a feeding conveyor belt and a discharging conveyor belt respectively.
In a preferred embodiment of the pre-screening mechanism provided by the present invention, the discharging conveyor belt is kept away from one end of the pre-screening mechanism is further provided with a turn-over mechanism.
In a preferred embodiment of the prescreening mechanism provided in the present invention, the turning mechanism is a set of soft rollers arranged in a "C" shape at the end of the discharging conveyor belt, and connected to another sorting conveyor belt.
Compared with the prior art, the utility model provides a screening mechanism will be in disorder hot pepper in advance regular, make it lay with roughly parallel angle on the discharging conveyor belt, make the workman can be rapidly, accurate complete letter sorting. And the turning mechanism is also arranged to sort the other side of the hot pepper at one time, so that the hot pepper with problems is fully removed.
Drawings
Fig. 1 is a side view of a pre-screening mechanism provided by the present invention;
fig. 2 is a sectional view taken along the line a-a in fig. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Please refer to fig. 1 and fig. 2, which are a side view and a sectional view in the direction of a-a of the pre-screening mechanism according to the present invention, respectively.
The pre-screening mechanism 1 comprises a screening barrel 2, a screen 3, a feeding conveyer belt 4, a discharging conveyer belt 5, a turn-over mechanism 6 and a sorting conveyer belt 7.
The screening cylinder 2 is a cuboid cylinder body, two ends of the screening cylinder in the length direction penetrate through the screening cylinder, and 5 layers of screens 3 are arranged in the screening cylinder in parallel at an angle vertical to the axial direction. Screen cloth 3 is the bar screen cloth by many body of rod parallel arrangement, and from top to bottom comprises 4~8 body of rods in proper order, promptly the density of screen cloth 3 from top to bottom crescent.
In the production process of pepper products, in order to ensure the stability of product quality and reduce the processing difficulty, the varieties with basically consistent size, batch and straight shape are generally selected. Based on the situation, the interval between the rod bodies of the lowest layer of the screen 3 is set to be 1.2 times of the average diameter of the batch of the hot pepper, the interval of the uppermost layer of the screen 3 is set to be 2.2 times, and the intervals of the three middle layers of the screens 3 are sequentially increased.
The top and the bottom of the screening cylinder 2 are respectively provided with the feeding conveyer belt 4 and the discharging conveyer belt 5. For ease of illustration, the side dams of each conveyor belt in fig. 1 have been removed. The feeding conveyer belt 4 is also provided with a speed control system, so that the feeding speed is adjusted in real time according to the quantity of the peppers and the residual quantity of the peppers in the screening cylinder 2, the peppers are guaranteed to be thrown into the screening cylinder 2 at a relatively stable speed, and the peppers are prevented from being accumulated.
A vibrating motor 21 is fixed on the outer wall of the screening cylinder 2, and under the vibration effect, the peppers sequentially pass through the screens 3, so that the peppers are finally regularly laid on the discharging conveyer belt 5 at a substantially parallel angle. Technical schemes such as a speed control system and control and power supply of the vibration motor 21 are mature prior art, and a person skilled in the art can select a proper scheme according to needs, and the detailed description is omitted.
The hot pepper is in behind the ejection of compact conveyer belt 5, the workman alright with carry out the first time and pick the hot pepper, remaining hot pepper continues to move to the end of ejection of compact conveyer belt 5. The turn-over mechanism 6 is provided here. The turn-over mechanism 6 is 5 soft rollers arranged close to the discharging conveyer belt 5. When the peppers continuously run to the position, the peppers are turned over under the compression of the rollers and fall on the sorting conveyer belt 7 arranged immediately behind the rollers, and then are picked for the second time by workers.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
