[0002] The working principle of the scraper type biscuit machine mainly depends on the cooperation of the dough feeding barrel, the scraper, the biscuit forming plate, the two feeding rollers, the motor, the translation driving device and the lifting cylinder. The feeding rollers and the scraper are arranged in the dough feeding barrel. Specifically, the dough is poured into the dough feeding barrel, the motor drives the two feeding rollers to rotate and extrude the dough, the dough flows downward, the lifting cylinder drives the scraper to lift, the dough feeding barrel and the scraper slide horizontally under the drive of the translation driving device, the scraper scrapes the dough in the dough feeding barrel into the forming holes of the biscuit forming plate, so that the biscuits are formed, and finally the biscuit forming plate is separated from the biscuit conveying belt, the biscuits remain on the conveying belt, and the forming process of the biscuits is completed. However, the above-mentioned scraper type biscuit machine has the following problems. First, the above-mentioned translation driving device is a translation motor driving gear rack mechanism, which drives the feeding barrel to translate. The gear rack needs to be lubricated, the lubricating oil is easy to contaminate food, and the gear rack is an open structure, which has food safety risks. Second, the dough feeding barrel of the existing scraper type biscuit machine is driven synchronously by a common motor and a gear box to rotate the two feeding rollers. The gear box is open, iron filings and lubricating oil generated are easy to contaminate food, and the common motor has poor control of feeding speed and precision. Third, the above-mentioned lifting cylinder is fixed to the side of the dough feeding barrel. When the dough feeding barrel is disassembled, the air pipe of the lifting cylinder needs to be removed. Therefore, the structure of the existing scraper type biscuit machine needs to be further improved. CONTENT OF THE UTILITY MODEL

[0065] The working principle of this utility model is as follows:

[0066] When this utility model is in operation, the conveyor belt 2 starts to run, the biscuit forming head 3 and the head drive mechanism 5 start to start. The head drive mechanism 5 drives the biscuit forming head 3 to move in an approximately square trajectory so that the biscuit forming head 3 can follow the speed of the conveyor belt 2 and form biscuits on the conveyor belt 2. Then it returns to the initial position and continues to form biscuits. This process is repeated to achieve mass production of biscuits.

[0067] The translation servo motor 41 drives the biscuit forming head 3 to perform reciprocating translational motion through the first translation drive component 47 and the second translation drive component 58, while the lifting servo motor 51 drives the biscuit forming head 3 to perform reciprocating lifting motion through the first lifting drive component 57 and the second lifting drive component 48. With the cooperation of the translation servo motor, the first translation drive component 47, the second translation drive component 58, and the lifting servo motor 51 through the first lifting drive component 57 and the second lifting drive component 48, the biscuit forming head 3 is finally made to move along an approximately square trajectory, so that the biscuit forming head 3 can follow the speed of the conveyor belt 2 and continuously form biscuits on the conveyor belt 2.

[0068] When the biscuit forming head 3 forms biscuits on the conveyor belt, the biscuit forming plate 33 of the biscuit forming head 3 descends onto the conveyor belt 2. The multiple lifting cylinders 62 of the conveyor belt lifting mechanism 6 lift the lifting plate 63, and the lifting plate 63 lifts the conveyor belt 2, so that the biscuit forming plate 33 abuts against the conveyor belt 2.

[0069] Meanwhile, the dough in the dough feeding hopper 32 is squeezed by the two feeding rollers 311 and flows downward to the bottom of the dough feeding hopper 32. Then, the first scraper lifting cylinder 39 drives the first scraper plate 312 to descend and abut against the biscuit forming plate 33. The second scraper lifting cylinder 310 drives the second scraper plate 313 to rise and leave the biscuit forming plate 33. Then, the feeding hopper translation servo motor 34 rotates forward. The feeding hopper translation servo motor 34 drives the feeding hopper sliding frame 38 and the dough feeding hopper 32 to slide from left to right through the feeding hopper translation transmission belt mechanism and the feeding hopper translation slider 35. The dough feeding hopper 32 slides from left to right on the biscuit forming plate 33. The dough in the dough feeding hopper 32 flows out of the dough feeding hopper 32 from the side of the second scraper plate 313 and fills the multiple biscuit forming holes 314 of the biscuit forming plate 33. The first scraper plate 312 scrapes the dough into the multiple biscuit forming holes 314.

[0070] After the dough feeding hopper 32 slides to the right and into position, the first scraper lifting cylinder 39 drives the first scraper plate 312 to rise and leave the biscuit forming plate 33, and the second scraper lifting cylinder 310 drives the second scraper plate 313 to descend. The lower end of the second scraper plate 313 abuts against the biscuit forming plate 33. Then, the feeding hopper translation servo motor 34 starts to reverse. The dough feeding hopper 32 slides from right to left on the biscuit forming plate 33. The dough in the dough feeding hopper 32 flows out of the dough feeding hopper 32 from the side of the first scraper plate 312 and fills into the multiple biscuit forming holes 314 of the biscuit forming plate 33. The second scraper plate 313 scrapes the dough into the multiple biscuit forming holes 314 and flattens the multiple biscuit forming holes 314. The dough fills the multiple biscuit forming holes 314, and biscuits are formed in the multiple biscuit forming holes 314. The thickness of the biscuit forming holes 314 is equal to the thickness of the biscuit forming holes 314. The biscuit forming effect is good, and there is no dough residue on the biscuit forming plate 33.

[0071] Subsequently, multiple lifting cylinders 62 drive the lifting plate 63 to descend, the lifting plate 63 disengages from the conveyor belt 2, and the biscuit forming plate 33 separates from the conveyor belt 2.

[0072] The head drive mechanism 5 drives the biscuit forming head 3 to rise, the biscuit forming plate 33 rises and leaves the conveyor belt 2, the biscuit remains on the conveyor belt, the conveyor belt 2 continues to transport the biscuit forward, and the head drive mechanism 5 drives the biscuit forming head 3 to return to the initial position to continue forming the next set of biscuits.
