Description

Technical Field

[0001] The present application relates to the technical field of food production, and specifically to a food production screening mechanism. Background Art

[0002] Food production screening refers to the screening and inspection of raw materials, processing equipment, production environment, etc. during the food production process to ensure that the food produced meets the hygiene and safety standards and quality requirements.

[0003] Food production screening is the preliminary preparation for the automatic cutting of food raw materials. Generally, food production screening is to classify raw materials of different sizes, as well as those that do not meet hygiene and safety requirements, such as defects in raw materials, so that different types of food raw materials can be cut and put into subsequent processing.

[0004] At present, mechanical screening such as vibration screening equipment, water immersion screening and other methods are usually used to screen food raw materials according to their size. When the food raw materials to be screened are restricted by the two screening methods, such as vibration will cause damage to the food raw materials, manual screening is usually performed to ensure that the food raw materials meet the requirements. Therefore, the current screening mechanism does not have better screening equipment under the condition of restrictions on the screening method of screening food. In this regard, a food production screening mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figures 1 to 3 A food production screening mechanism in this embodiment includes a mounting frame 1 and a chain frame 2 fixed on the top of the mounting frame 1, and a conveying roller 3 for conveying food is arranged in the chain frame 2, wherein the number of the conveying rollers 3 is several, and the several conveying rollers 3 are closely arranged to reduce the risk of food raw materials falling from between adjacent conveying rollers 3.

[0023] It should be noted that the end of the conveyor roller 3 is driven by a chain. The chain can be connected in a one-to-one manner, or several conveyor rollers 3 can be directly sleeved in a meshing manner. When the chain is small, it is difficult to connect in a one-to-one manner. In this case, an overall sleeve is selected. In order to avoid the problem of too small an angle of wrap, a sprocket with a larger tooth shape is required to mesh with the chain. The conveyor roller 3 at the end is connected to the output end of the motor for driving for driving.

[0024] In this embodiment, a guide plate 4 for guiding food raw materials is fixedly mounted on the outer side of the chain frame 2, and a sorting mechanism for optically detecting bad food raw materials is provided on the mounting frame 1.

[0025] In the present application, food raw materials are conveyed and screened by the conveying roller 3, and the matching raw materials passing through the sorting mechanism are loaded on one side of the conveying roller 3 and identified by optical detection. In the case of defective products, the food raw materials are pushed out from the guide plate 4 at the corresponding position by the sorting mechanism to achieve sorting.

[0026] It should be noted that the sorting mechanism includes an optical lens 11 fixedly mounted on the mounting frame 1, a fixing frame 7 fixedly mounted between the mounting frames 1, a cylinder 8 fixed on the fixing frame 7, and a push plate member connected to the cylinder 8, wherein the push plate member includes two top plates 5 arranged in parallel, the two top plates 5 are fixedly connected by a fixing plate 6, and the piston rod end of the cylinder 8 is fixedly connected to the fixing plate 6.

[0027] Preferably, the top surface of the top plate 5 is an inclined surface and is inclined toward the guide plate 4 on one side. The distance between the two top plates 5 corresponds to the distance between the conveying rollers 3, so that the top plate 5 can extend to both sides of a conveying roller 3, so that the food raw materials on the conveying roller 3 can be pushed out.

[0028] In a specific implementation, when the optical lens 11 captures surface defects of food raw materials, the external controller controls the cylinder 8 to lift up by transmitting signals, and the top plate 5 connected to the cylinder 8 is pushed out to the top of the conveying roller 3 to lift the food raw materials. The food raw materials roll down onto the guide plate 4 along the inclined direction of the top plate 5.

[0029] This design has the advantage of saving space compared to the method of direct pushing with a side-mounted cylinder. In addition, the food raw materials fall down due to their own weight, which slows down the falling speed compared to the force that needs to be overcome by pushing, thus helping to improve the safety of sorting.

[0030] In order to guide the movement of the top plate 5, in this embodiment, a guide rod 9 is fixedly installed on the fixed plate 6, a guide tube 10 is fixedly installed through the fixed frame 7, and the guide rod 9 is slidably connected to the guide tube 10. Through the relative sliding of the guide rod 9 and the guide tube 10, the lifting stability of the top plate 5 can be improved.

[0031] In this embodiment, a drop mechanism is also provided on one side surface of the chain frame 2 for size sorting of food raw materials after surface screening. The drop mechanism includes a support plate 13 fixedly mounted on one side surface of the chain frame 2 and a baffle rod 12 hinged between the support plate 13 and the chain frame 2.

[0032] It should be noted that the support plate 13 is fixed by vertically welding a crossbar between the support plate 13 and the chain frame 2 . The baffle bars 12 include a plurality of baffle bars 12 , and the spacing between adjacent baffle bars 12 gradually increases from the chain frame 2 toward the support plate 13 .

[0033] By changing the distance between the baffle bars 12, food raw materials of different sizes can be rolled, sorted and dropped.

[0034] In this embodiment, a telescopic rod 14 is fixedly connected to one end of the barrier rod 12 , the telescopic rod 14 and the support plate 13 are hinged to each other, and a slide plate 15 slidably connected to the chain frame 2 is hinged to the other end of the barrier rod 12 .

[0035] In a specific implementation, the distance between adjacent blocking rods 12 can be adjusted by sliding the slide plate 15 to improve the applicability of screening, and bolts should be installed on the slide plate 15 for fixing the position.

[0036] The working principle of the above embodiment is:

[0037] By loading the food raw materials from one side of the conveying roller 3, the food raw materials are conveyed along the transmission direction of the conveying roller 3. When the food raw materials pass through the optical lens 11 on the mounting frame 1, the optical lens 11 transmits a signal to control the cylinder 8 to push out, and the top plate 5 connected to the cylinder 8 is lifted up, so that the food raw materials slide along the inclined surface above the top plate 5 and roll down to the guide plate 4 on one side of the chain frame 2 for screening;

[0038] After the appearance screening, the food raw materials pass through the end position of the conveying roller 3 and fall to the position between the adjacent baffles 12, and roll along the inclined baffles 12. The small-sized food raw materials fall first, and then the large-sized food raw materials fall at different positions to achieve sorting.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0040] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
