Referring to fig. 4 and 5, an embodiment of a food product flatting machine according to the present invention includes an endless conveyor 3 including: a driving wheel 301, a driven wheel 302 and a conveyor belt 303. The support frame 1 is provided with a first motor 101, and the first motor 101 is positioned at one side close to the driving wheel 301. The driving wheel 301 is in transmission connection with the first motor 101 through a chain. The conveyer belt 303 adopts a Polyurethane (PU) conveyer belt 303, and the Polyurethane (PU) conveyer belt 303 uses a specially treated polyester composite fabric as a bearing framework and is coated with Polyurethane (PU) resin as a carrying surface.

The scraper 5 is a rectangular scraper 5, the length direction of the scraper 5 is perpendicular to the conveying direction of the annular conveying member 3, and the length of the scraper 5 is slightly larger than the width of the conveying belt 303, so that the scraper 5 can completely scrape off the sugar on the conveying belt 303. In order to improve the sugar scraping effect of the scraper 5, the top of the scraper 5 is abutted against the outer surface of the conveyor belt 303, and the top surface of the scraper 5 is designed as a slope. Wherein the rotation direction of the scraper 5 along with the sleeve 601 in fig. 5 is counterclockwise.

Referring to fig. 1, 3 and 7, a tension wheel 103 is disposed on both sides of the scraper 5, and the tension wheel 103 is located inside the conveyor belt 303 and abuts against the conveyor belt 303. Because conveyer belt 303 has certain flexibility, when scraper 5 supported and leans on conveyer belt 303, certain deformation can take place for conveyer belt 303, results in scraper 5 not good to the clean effect of the sugar layer on conveyer belt 303, makes conveyer belt 303 and scraper 5 compress tightly each other through take-up pulley 103, has improved scraper 5 and has scraped sugar effect.

One end of the screw 105 is rotatably connected to the support frame 1, and the other end is in threaded connection with the first support shaft 104. The lead screw 105 is rotated to drive the tension pulley 103 to move in the vertical direction, so that the distance between the tension pulley 103 and the conveying belt 303 is adjusted, and finally the pressing force between the scraper 5 and the conveying belt 303 is changed. In order to facilitate the operation of the screw 105, a handle 106 is attached to an end of the screw 105, and the handle 106 and the screw 105 are fixed by welding. The operator drives the screw 105 by means of the handle 106, so that the labor intensity is reduced, and the working efficiency is improved. In order to improve the stability of the tension pulley 103 in the movement process, a guide groove 107 in sliding fit with the first support shaft 104 is formed in the support frame 1, and the guide groove 107 is in an oval shape.

Referring to fig. 1 to 5 and 10, as an embodiment of the food leveling machine provided by the present invention, a second motor 102 is mounted on the supporting frame 1, and the second motor 102 is located at one side of the sleeve 601. The second motor 102 is in transmission connection with the sleeve 601 through a chain. The number of the scrapers 5 is plural, and is uniformly arranged along the circumferential direction of the sleeve 601. The driving mechanism drives the scraper 5 to slide in the first sliding chute 602 along the radial direction of the scraper 5 while the scraper 5 is driven to rotate by the sleeve 601. When the scraper 5 slides in the first sliding groove 602, the sugar on the scraper 5 is scraped, and the scraper 5 is cleaned, so that the sugar scraping effect of the scraper 5 is improved. Due to the low conveying speed of the annular conveying member 3, the sugar scraping effect of the scraping blades 5 in the rotating process can be met by adjusting the rotating speed of the sleeve 601 and the number of the scraping blades 5. In order to prevent the sleeve 601 from splashing sugar during rotation, causing pollution to the surrounding environment and waste of sugar, a storage box 7 is mounted on the support frame 1 for collecting sugar scraped from the annular conveying member 3 and the scraper 5. The storage box 7 and the support frame 1 are fixed through a clamping structure, screw installation is not needed, and dismounting and mounting are convenient.

The highest point of the cam 610 refers to a point at which the outer edge of the cam 610 is farthest from the rotational axis of the cam 610; the lowest point of the cam 610 refers to a point at which the outer edge of the cam 610 is closest to the rotational axis of the cam 610. In this embodiment, because scraper 5 is in the rotary motion state, when scraper 5 rotates to break away from with conveyer belt 303 and is in idle running state, actuating mechanism drive scraper 5 is along the radial central motion to being close to sleeve 601 of sleeve 601, make the part of scraper 5 protrusion sleeve 601 can contact with first spout 602 completely, actuating mechanism drive scraper 5 is along the length that the motion stroke more than or equal to scraper 5 protrusion sleeve 601 of first spout 602, guarantee that the sugar on scraper 5 can thoroughly be cleared up, neither influence the normal work of scraper 5, the clearance effect to scraper 5 has been improved again. The cam 610 is fixedly connected with the second support shaft 108. One end of the scraper 5, which is abutted against the cam 610, is an arc surface, so that the scraper 5 can conveniently slide along the peripheral surface of the cam 610. The elastic restoring member 611 may be made of a spring or polyurethane. Since the elastic restoring member 611 requires a high frequency of compression deformation, the spring is preferred in the present application, and the spring is always in a compressed state, ensuring that the scraper 5 can always contact the cam 610. The number of the springs is four, and the springs are symmetrically arranged along the center of the scraper 5. The scraper 5 is provided with a guide post 612, and the guide post 612 is arranged corresponding to the spring and used for guiding and limiting the spring, so that the spring is prevented from being separated from the scraper 5 and the surrounding plate 604 due to unstable stress, and the movement of the scraper 5 along the first sliding groove 602 is prevented from failing.

In this embodiment, the driving mechanism is placed inside the sleeve 601, so that the utilization rate of the space is effectively improved, and the space occupied by the driving mechanism is saved. Since the sugar cleaned from the scraper 5 passes through the space between the surrounding plate 604 and the conveyor belt 303, it falls into the storage box 7. By processing the inclined plane 605 on the outer side surface of the enclosing plate 604, the distance between the enclosing plate 604 and the conveying belt 303 is increased, so that the sugar falling from the scraper 5 can smoothly slide outwards. The support frame 1 is provided with a second support shaft 108, and the end cover 603 is sleeved on the second support shaft 108. And a second rolling bearing 109 is also arranged between the end cover 603 and the second support shaft 108, so that the friction resistance between the end cover 603 and the second support shaft 108 is effectively reduced, and the transmission efficiency is improved.
