[0049] In summary, with the aid of the above technical solutions of the present invention, in order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below:

[0050] In actual application, bread or other food to be spread with cream is first placed manually on the sensing through hole 4 on the conveyor belt 2, and the conveyor belt 2 will drive the bread or food to move. When the sensing through hole 4 moves to the bottom of the sensor 11, the sensor 11 will detect that there is an object on the sensing through hole 4, and the conveyor belt 2 will stop moving through the controller 35. At the same time, the electromagnetic control valve on the discharge pipe 9 is opened, and the pump body 8 is started to draw the cream in the storage box 7 into the discharge pipe 9 to flow out. The cream will fall from the discharge cover 10 onto the bread or food, thereby realizing the automatic material dropping process. When the cream leaks out, the flow meter will measure the amount of the cream flowing out, which greatly increases the accuracy of the cream discharge. After the cream falls out, the controller will control the start of the pump body 8 and the electromagnetic control valve, and control the conveyor belt 2 to convey. When bread or food with cream passes under the scraper, the scraper will scrape the cream flat. When the cream needs to be scraped flat in a circular shape, the second motor 20 is started, and the second motor 20 will drive the rotating shaft 19 to rotate, thereby driving the scraper 21 to rotate, so that the cream can be spread into a circle, which greatly increases the convenience of use.

[0051] When the thickness of the cream needs to be adjusted, the first motor 17 can be started. The start of the first motor 17 will drive the first threaded rod 16 to rotate. The rotation of the first threaded rod 16 will drive the nut 14 to move in the sliding groove 15, thereby driving the lifting plate 13 to move up and down, thereby adjusting the distance between the scraper 21 and the bread or food, thereby adjusting the thickness of the cream. The bread or food after the cream is applied will be conveyed to the other end of the conveyor belt 2 and conveyed to the next process.

[0052] When the scraper 21 is applied to the cream, it will adhere to the surface of the scraper 21. When a large amount of cream adheres to the scraper 21, the entire device is stopped, and then the first hydraulic cylinder 23 is started. The first hydraulic cylinder 23 will drive the first hydraulic rod 22 to extend, thereby pushing the second motor 20 to the other end of the slide groove, and then the third motor 32 is started. The start of the third motor 32 will drive the second threaded rod 27 to rotate, thereby driving the moving block 25 to move in the limiting slide groove 26. Since the first L-shaped plate 24 is connected to the moving block 25, the movement of the first L-shaped plate 24 is realized. At the same time, the second L-shaped plate 28 is fixed to one side of the first L-shaped plate 24, and the second The L-shaped plate 28 is in contact with the scraper 21, so that the cream adhering to the scraper 21 is scraped off, and then the second hydraulic cylinder 31 is started. The start of the second hydraulic cylinder 31 will drive the second hydraulic rod 30 to extend, pushing the pushing plate 29 down, so as to push the cream on the second L-shaped plate 28 into the collecting box 38, thereby collecting the cream and avoiding a large amount of cream adhering to the scraper 21 to affect the spreading of bread or food, greatly improving the quality of the spreading of the cream, avoiding the staff from disassembling and cleaning the scraper, greatly increasing the convenience of cleaning, reducing the labor intensity of the staff, and greatly improving the work efficiency.

[0053] Although embodiments of the present invention 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 invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
