Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and more particularly to a food paving machine. Background Art

[0002] Food refers to various substances that can be eaten or drunk by humans, including processed food, semi-finished products and unprocessed food, such as grains, fruits, vegetables, meat, dairy products, soy products, beverages, etc. In the food processing process, the flattening machine is an important equipment that can ensure that the food is flat before processing, packaging or storage, thereby improving the quality and appearance of the food. The food flattening machine of the present invention is particularly suitable for processing scenarios that require food materials to be evenly spread on various carriers, such as spreading dough for baked goods, spreading slices of meat products, etc.

[0003] According to the patent document: CN110844532B, a food flattening machine disclosed belongs to the technical field of food processing equipment and includes: a support frame, a hopper, an annular conveyor, an extrusion roller, a scraper, a sleeve, and a drive mechanism. The hopper is used to hold puffed materials, and a discharge port is provided below the hopper; the annular conveyor is located below the hopper and is used to convey the puffed materials to the next process; the extrusion roller is rotatably arranged on the support frame and is located above the annular conveyor; the scraper is located below the annular conveyor and is in contact with the sugar layer on the annular conveyor; the sleeve is rotatably arranged on the support frame, and the axis of the sleeve is perpendicular to the conveying direction of the annular conveyor, and the sleeve is provided with a first slide groove that slides with the scraper; the drive mechanism is used to drive the scraper to reciprocate along the radial direction of the sleeve. The food flattening machine provided by the present invention has a first slide groove that slides with the scraper on the sleeve, which realizes the cleaning of the sugar on the scraper, thereby improving the sugar scraping effect of the scraper.

[0004] When processing dried sweet potatoes, since the shapes of dried sweet potatoes are usually irregular after preliminary processing, they need to be flattened in order to make them better bagged. The traditional flattening method usually uses a conveyor to convey the dried sweet potatoes and rotates them through a crawler set on the top to flatten them. However, when flattening the dried sweet potatoes in this way, since the dried sweet potatoes have a certain stickiness, the dried sweet potatoes are easily stuck to the extrusion crawler or adhere to the surface of the conveyor table when they are squeezed and flattened, thereby affecting the subsequent flattening effect and subsequent processing efficiency. In addition, the traditional flattening device can only extrude and flatten in one direction, which may cause the dried sweet potatoes to be unevenly stressed during the flattening process, and some areas remain in their original state.

The middle part of the rear side of the third turntable 3115 is fixedly connected to the front end of the leftmost columnar rotating rod 22. The longitudinal paving assembly 32 includes two hinge blocks 321. Both sides of the bottom of the inner wall of the two hinge blocks 321 are rotatably connected to the expansion block rotating rod 322.

[0039] When the dried sweet potatoes are initially flattened and transferred to the bottom of the longitudinal flattening mechanism 3, due to the rotation of the leftmost columnar rotating rod 22, and the front end of the leftmost columnar rotating rod 22 is fixed to the middle of the rear side of the third turntable 3115, the third turntable 3115 rotates accordingly, and the third turntable 3115 drives the second turntable 3110 to rotate through the second transmission crawler 3114, and the second turntable 3110 drives the front diamond-shaped rotating block rotating rod 319 to rotate, and the front diamond-shaped rotating block rotating rod 319 rotates through the diamond-shaped rotating block 3112 and the rotating rod 3113. The cooperation drives the elliptical pressure plate 317 to reciprocate up and down, and the elliptical pressure plate 317 drives the two columnar uprights 315 to reciprocate up and down under the elastic force of the second spring 316.

After the dried sweet potatoes are flattened, they continue to be transported forward. At this time, the residue falling from the extrusion track 214 will fall on the inner wall of the residue collection frame 3117 for collection, avoiding the residue falling on the inner wall of the device, improving the cleanliness of the device, and facilitating the centralized treatment of the residue.

[0040] like Figure 10As shown, the right sides of the two L-shaped connecting rods 41 are fixedly connected to the left sides of the two connecting cross plates 213, and the sides of the bottoms of the two L-shaped connecting rods 41 away from each other are fixedly connected to the columnar push-pull vertical rods 42, and the outer wall bottoms of the two columnar push-pull vertical rods 42 are sleeved with columnar push-pull vertical rod guide blocks 43, and the right sides of the two columnar push-pull vertical rod guide blocks 43 are fixedly connected to the front and rear sides of the left rectangular connecting frame 311, and the bottoms of the two columnar push-pull vertical rods 42 are rotatably connected to the inclined plates 44, and the front and rear sides of the two inclined plates 44 are fixedly connected to the side connecting blocks 45, and the right sides of the inner sides of the two side connecting blocks 45 are rotatably connected to the outer ends of the two columnar hinge blocks 318, and the middle part of the bottom of the inclined plate 44 is fixedly connected to the scraper 46;

[0041] When the two connecting horizontal plates 213 move back and forth up and down, the two columnar push-pull uprights 42 are driven to move back and forth on the inner wall of the columnar push-pull upright guide block 43 by the two L-shaped connecting rods 41.

The multiple groups of inverted U-shaped rotating plates 325 and the two groups of expansion blocks 323 drive multiple groups of squeezing rollers 326 to longitudinally flatten the dried sweet potatoes. In the process of longitudinally flattening the dried sweet potatoes, the up and down reciprocating movement of the elliptical pressing plate 317 drives the two connecting cross plates 213 to move back and forth, thereby driving the lifting cross bar 210 to move back and forth through the two L-shaped cross connecting rods 212. The lifting cross bar 210 drives the extrusion crawler scraper roller 211 to reciprocate up and down with the extrusion crawler The surface of the belt 214 is fitted to scrape the surface of the extrusion crawler 214. At this time, the residue falling from the extrusion crawler 214 will fall on the inner wall of the residue collection frame 3117 for collection. At the same time, when the two connecting cross plates 213 move back and forth up and down, the two columnar push-pull vertical rods 42 are driven by the two L-shaped connecting rods 41 to move back and forth on the inner wall of the columnar push-pull vertical rod guide block 43. The two columnar push-pull vertical rods 42 drive the two inclined plates 44 to swing with the columnar hinge block 318 as the axis. The two inclined plates 44 drive the two scrapers 46 to scrape the conveyor belt of the conveyor platform 1 to prevent the dried sweet potatoes from being squeezed and flattened and adhering to the conveyor belt of the conveyor platform 1. At the same time, the scraping action of the two scrapers 46 can also effectively clean the dried sweet potato debris that may remain on the conveyor belt.
