Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a food processing empty package screening device. Background Technology
[0002] With the development of society, the food industry now uses mechanized production. The last step in the food production line is to package the finished food. However, due to problems in a previous step, empty bags may appear during the final packaging. Empty bags are defective products and cannot enter the market, so they need to be sorted out.
[0003] In the food processing process, especially for some expanded foods, the packaging bags are filled with a large amount of gas to ensure food safety. However, empty bags are inevitable during processing and packaging. When screening empty bags for these products, the most commonly used method is to use sensor devices, mainly pressure sensors, which rely on the light weight of empty bags for screening. At the same time, wind screening is also currently used, which uses wind to blow away the light blank bags.
[0004] While the above methods can achieve the screening of empty packages, they all require the addition of other equipment to the production line, which not only increases production costs but also affects the production workshop. For example, empty packaging bags may fall off directly when affected by wind.
[0005] Therefore, we propose a food processing empty package screening device to solve the above-mentioned defects and problems. Utility Model Content
[0006] The purpose of this invention is to provide a food processing empty package screening device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A food processing empty package screening device includes an inclined frame structure. Both ends of the side of the frame structure are equipped with a power shaft via a bearing structure. A conveyor roller is connected to the end of the power shaft. A conveyor belt is fitted on the outer ring of the conveyor roller. A linkage shaft is installed in the middle of the side of the frame structure via a bearing structure. A undulating roller is connected to the end of the linkage shaft. A protruding strip is provided on the outer wall of the undulating roller.
[0009] Preferably, the diameter of the conveying roller is the same as the diameter of the undulating roller.
[0010] Preferably, the tilt angle of the tilted frame structure is 20-30°.
[0011] Preferably, anti-slip strips are provided at equal intervals on the top of the conveyor belt.
[0012] Preferably, a drive motor is installed on the outer wall of the frame structure, and the output shaft of the drive motor is connected to one of the power shafts.
[0013] Preferably, a wheel structure is fitted on the outer ring of the power shaft and the linkage shaft located on the left side, and a belt is fitted on the outer ring of the wheel structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This food processing empty package screening equipment, through its inclined frame structure, conveying structure, and the design and use of undulating rollers with protruding strips, allows lightweight empty packages to slide off directly during food packaging transfer and conveying due to the bumpy and turbulent motion combined with the inclined surface design. This achieves empty package screening without the need for additional equipment and without affecting the production workshop. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] See Figure 1-2 This utility model provides a technical solution for a food processing empty package screening device:
[0021] Example:
[0022] The empty package screening equipment mainly includes a frame structure 1. On both sides of the frame structure 1, a power shaft 2 is installed through a bearing structure. A conveyor roller 3 is connected and installed at the end of the power shaft 2. A linkage shaft 6 is installed in the middle of the side of the frame structure 1 through a bearing structure. A wave roller 7 is connected and installed at the end of the linkage shaft 6. A conveyor belt 4 for transferring packaged products is fitted on the outer ring of the conveyor roller 3. The entire frame structure 1 is tilted to the rear. Protruding strips 8 are set at equal intervals on the outer wall of the wave roller 7.
[0023] The diameter of the conveying roller 3 is equal to the diameter of the undulating roller 7.
[0024] Among them, a wheel structure 9 is fitted on the outer ring of the power shaft 2 and the linkage shaft 6 on the left side, and a belt 10 is fitted on the outer ring of the wheel structure 9.
[0025] Among them, the rearward tilt angle of frame structure 1 is 20-30°.
[0026] Anti-slip strips 5 are evenly spaced on the top of the conveyor belt 4.
[0027] A drive motor is installed on the outer wall of the frame structure 1, and the output of the drive motor is connected to one of the power shafts 2.
[0028] In this embodiment, the entire device is directly installed on the production line and connected to the previous process. The finished products from the previous process fall directly onto the conveyor belt 4. As the drive motor operates, it drives the conveyor roller 3 to rotate. The rotation of the conveyor roller 3 drives the power shaft 2 and the conveyor belt 4 to rotate cyclically. When the power shaft 2 rotates, it drives the linkage shaft 6 to rotate through the wheel structure 9 and the belt 10, which in turn drives the undulating roller 7 to rotate. When the undulating roller 7 rotates, it drives the protruding strip 8 on it to rotate cyclically. When the protruding strip 8 rotates cyclically, it periodically lifts the conveyor belt 4 and then falls back instantly, shaking the packaged products on the conveyor belt 4. The falling time of the lightweight empty package is slower than that of the packaged bag containing food. Therefore, when the lightweight empty package falls while the conveyor belt 4 is still conveying food, it will fall onto the next packaged bag being conveyed. The empty package cannot disengage from the anti-slip strip 5 and falls down along the inclined surface.
[0029] In this technical solution, through the design and use of the inclined frame structure 1 and its conveying structure and the wave roller 7 with protruding strips 8, during the transfer and conveying of food packaging, the entanglement and bumping combined with the inclined surface design allow lightweight empty packages to slide off directly, achieving empty package screening without the addition of additional equipment and without affecting the production workshop.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
