[0023] The molding component 4 includes a molding die 401, which is fixedly installed between two guide chains 303 distributed front and back. The upper and lower surfaces of the molding die 401 are penetrated with a plurality of molding cavities 402 distributed front and back. A compression sleeve 403 is slidably installed inside the molding cavity 402. A top plate 404 is fixedly installed on the top of the outer wall of the compression sleeve 403. The top plate is a cylindrical structure with an inverted L-shaped cross section, that is, a flange on the top and a cylindrical sleeve on the bottom. A reset spring 405 is fixedly installed between the bottom of the top plate 404 and the top of the molding die 401, and the reset spring 405 is sleeved on the outside of the compression sleeve 403.

[0024] Two left-right distributed filling components 5 are fixedly installed inside the frame 1. The filling components 5 are located between the two front and rear guide chains 303. The filling components 5 include a raw material bucket 503 located above and connected to the frame. A plurality of front-back distributed feeding pipes 501 are fixedly installed at the bottom of the raw material bucket 503. The positions of the feeding pipes 501 match the positions of the molding cavity 402. Two left-right distributed compacting components 6 are fixedly installed inside the frame 1. The compacting components 6 and the filling components 5 are alternately distributed along the left and right directions of the device. A lifting cylinder 601 is fixedly installed at the bottom of the compacting component 6. The lifting cylinder can be an electric cylinder or a pneumatic cylinder. A pressure plate 602 is fixedly installed at the bottom of the output rod of the lifting cylinder 601, and a plurality of pressure plates 603 distributed front and back are fixedly installed at the bottom of the pressure plate 602. The positions of the plurality of pressure plates 603 correspond one to one with the positions of the plurality of molding cavities 402. An electromagnetic material valve 502 is fixedly installed at the bottom of the feeding pipe 501, and a controller 7 is fixedly installed at the top of the frame 1. The output end of the controller 7 is electrically connected to the electromagnetic material valve 502.

[0025] Specifically, the output shaft of the power motor 204 drives the active pulley 205 to rotate, and further drives the driven pulley 206 and a conveying shaft 201 and a conveying roller 202 connected to the driven pulley 206 to rotate together under the transmission action of the power belt 207. Further, under the joint action of the other conveying shaft 201 and the conveying roller 202 on the conveying belt 203, the conveying belt 203 is caused to run rightward along the left and right conveying rollers 202. Since the top of the conveying belt 203 abuts against the surface of the forming mold 401 located at the upper end thereof, the static friction between the conveying belt 203 and the forming mold 401 drives the forming mold 401 in contact with the top of the conveying belt 203 to move rightward together, and Under the rotation support of the guide chain 303, the front and rear two guide chains 303 rotate around the four guide sprockets 302, and the remaining multiple forming molds 401 are driven to rotate together through the connection with the front and rear two guide chains 303. During the rotation, the forming mold 401 will drive the compression sleeve 403 to move together. When the compression sleeve 403 moves to the bottom of a raw material hopper 503 located on the left, the power motor 204 is turned off, and the multiple electromagnetic material valves 502 at the bottom of the left end raw material hopper 503 are opened. The food raw materials located inside the raw material hopper 503 fall into the interior of the multiple compression sleeves 403 directly below it and the forming molds through the front and rear multiple feeding tubes 501. The interior of the molding cavity 402, and under the support of the top of the conveyor belt 203, the food raw materials filled in the molding cavity 402 will not fall down. When the interior of the molding cavity 402 and the interior of the compression sleeve 403 are filled with food raw materials, the electromagnetic material valves 502 are closed to block the continued discharge of the raw material bucket 503, and the power motor 204 is started to make the conveyor belt 203 continue to run to the right, further causing the molding mold 401 filled with food raw materials and the compression sleeve 403 to move to the right together, until they move to the bottom of a fixed crossbeam 604 at the left end, and then the power motor 204 is closed again, the conveyor belt 203 stops moving, and then the lifting cylinder 601 is started, so that the output rod of the lifting cylinder 601 drives the pressing plate 602 to move downward , push the front and rear multiple pressure plates 603 downward, the multiple pressure plates 603 move downward and abut against the tops of the multiple top plates 404 located at the bottom thereof, thereby pressing the top plates 404 downward, and the downward pressing movement of the top plates 404 drives the compression sleeve 403 and the elastic airbag 406 fixed inside the compression sleeve 403 to move downward together. As the compression sleeve 403 moves downward, it will slide into the interior of the molding cavity 402, causing the space formed by the compression sleeve 403 and the molding cavity 402 to shrink continuously, thereby squeezing the food raw materials located inside the compression sleeve 403 and the molding cavity 402 to give them a preliminary molding, and then start the lifting cylinder 601 to move its output rod upward to lift the pressure plate 602 together with the pressure plate 603 upward, and then start the power motor 204 again,The conveyor belt 203 continues to rotate to convey the food that has been preliminarily formed in the previous step to the bottom of a raw material hopper 503 located at the right end. When the preliminarily formed food and the forming mold 401 are moved to the bottom of the raw material hopper 503 located on the right, the power motor 204 is closed again, and the electromagnetic material valves 502 located at the bottom of the right raw material hopper 503 are opened to allow the second raw material inside the raw material hopper 503 to fall into the compression sleeve 403 at its bottom through the feeding pipe 501, that is, the top of the preliminarily formed food. When the compression sleeve 403 is filled with the second raw material, the electromagnetic material valve 502 is immediately closed, and the power motor 204 is started to fill the second raw material. After the second raw material forming mold 401 moves to the bottom of the fixed crossbeam 604 located on the right, the power motor 204 is turned off and the lifting cylinder 601 is started. The output rod of the lifting cylinder 601 moves downward, pushing the pressing plate 602 and the pressure plate 603 downward, squeezing the top plate 404 and the compression sleeve 403 downward, so that the second raw material is squeezed together with the food blank formed in the previous step. Then the lifting cylinder 601 is started, so that its output rod moves upward to lift the pressing plate 602 and the pressure plate 603 upward, releasing the downward pressure on the top plate 404, and the resilience of the return spring 405 pushes the top plate 404, the compression sleeve 403 and the elastic airbag 406 upward.

[0026] In the second embodiment, a side of the molding die 401 close to the top plate 404 is provided with an annular air groove 4010, which is located at the periphery of the molding cavity 402. A compressed air cylinder 408 is slidably installed inside the annular air groove 4010, and the top of the compressed air cylinder 408 is fixedly connected to the bottom of the flange of the top plate 404. A blowing cavity 409 is provided inside the compressed air cylinder 408, and the blowing cavity 409 is in an inverted L shape. The inverted L-shaped vertical channel passes through the bottom of the compressed air cylinder 408, and the inverted L-shaped transverse channel passes through the inner wall of the compressed air cylinder 408 transversely. A transverse blowing hole 407 is provided through the upper part of the inner wall of the compression sleeve 403, and the position of the blowing hole 407 corresponds to the position of the blowing cavity 409, and they are connected to each other. An elastic air bag 406 is fixedly installed on the inner wall of the compression sleeve 403, and the elastic air bag 406 is located at the periphery of the opening of the blowing hole 407. That is, the channel in the compressed air cylinder 408 and the elastic airbag 406 are connected to each other through the blowing hole 407 in the compression sleeve 403.

[0027] An annular piston 4012 is slidably installed inside the annular air groove 4010, and a plurality of top springs 4013 distributed at equal angles are fixedly installed between the bottom of the annular piston 4012 and the bottom wall of the annular air groove 4010. A transverse pressure relief air duct 4011 is penetrated through the inner wall of the annular air groove 4010 away from the compression sleeve 403. The pressure relief air duct 4011 is located at the bottom of the annular piston 4012, one end of which is opened on the inner wall of the annular air groove 4010 below the annular piston 4012, and the other end is opened to communicate with the atmosphere.

[0028] Specifically, in this embodiment, the output rod of the lifting cylinder 601 drives the pressure plate 602 to move downward, pushing the front and rear pressure plates 603 downward, and the pressure plates 603 move downward and abut against the tops of the top plates 404 located at the bottom thereof, thereby pressing the top plates 404 downward. The downward pressing movement of the top plates 404 drives the compressed air cylinder 408 to move downward along the inner wall of the annular air groove 4010, compressing the air inside the annular air groove 4010. The compressed air inside the annular air groove 4010 enters the blowing cavity through the bottom of the blowing cavity 409. After the food is inside the food container 409, it is compressed from the top of the blowing cavity 409 to the area between the inner wall of the compressed gas cylinder 408 and the outer wall of the compression sleeve 403, and then transported to the inside of the elastic airbag 406 through the blowing hole 407, so that the deflated elastic airbag 406 gradually bulges, squeezes the outer wall of the formed food, and makes the outer wall of the food shrink to the middle by an appropriate amount. When the bottom of the compressed gas cylinder 408 moves downward and contacts the top of the annular piston 4012, as the compressed gas cylinder 408 continues to move downward, the annular piston 4012 is pushed downward, resulting in multiple The top spring 4013 is compressed, and when the annular piston 4012 moves to the bottom position of the pressure relief airway 4011, the pressure relief airway 4011 is connected to the inside of the blowing cavity 409 through the annular air groove 4010. At this time, the hollow elastic airbag 406 shrinks under the action of the rebound force and returns to the empty state, and the air inside the elastic airbag 406 is discharged into the area between the outer wall of the compression sleeve 403 and the inner wall of the compression cylinder 408 through the blowing hole 407 under the action of the rebound force of the elastic airbag 406, and then discharged into the annular air groove through the blowing cavity 409 After the pressure inside the food 4010 is released, it is discharged to the outside through the pressure relief air duct 4011, and then the lifting cylinder 601 is started to move its output rod upward to lift the pressure plate 602 and the pressure plate 603 upward, thereby releasing the downward pressure on the top plate 404. The rebound force of the return spring 405 pushes the top plate 404, the compression sleeve 403 and the elastic airbag 406 to move upward. After the top plate 404 is deflated, its inner wall is separated from the outer wall of the food. Therefore, when the elastic airbag 406 moves upward, it will not carry the formed food upward, thereby facilitating the demolding of the food.

[0029] In the third embodiment, the diameter of the pressure plate 603 is larger than the inner diameter of the compression sleeve 403; Specifically, in this embodiment, by directly setting the size of the pressure plate 603 to be larger than the diameter of the compression sleeve 403, it is possible to avoid the pressure plate 603 being directly inserted into the interior of the compression sleeve 403, thereby ensuring that the pressure plate 603 can be pressed on the top of the top plate 404 to push the top plate 404 together with the compression sleeve 403 downward.

[0030] In the fourth embodiment, the top of the conveyor belt 203 is fitted with the bottom of the molding die 401 located on the top thereof; Specifically, in this embodiment, since the top of the conveyor belt 203 is in contact with the bottom of the molding die 401 located on the top thereof, due to the static friction between the two, when the conveyor belt 203 is running, it can drive the molding die 401 in contact therewith to move together, so that the entire guide component 3 and the molding component 4 can be operated.

[0031] In the present scheme, a belt-type forming machine for pancake-shaped food is operated by starting the power motor 204, and the output shaft of the power motor 204 drives the driving pulley 205 to rotate, and further drives the driven pulley 206 and a conveying shaft 201 and a conveying roller 202 connected to the driven pulley 206 to rotate together under the transmission action of the power belt 207, and further under the joint action of the other conveying shaft 201 and the conveying roller 202 on the conveying belt 203, the conveying belt 203 is caused to run to the right along the left and right conveying rollers 202, and because the top of the conveying belt 203 is in contact with the surface of the forming mold 401 located at the upper end thereof, the static friction between the conveying belt 203 and the forming mold 401 drives the conveying belt 203 to rotate. The molding mold 401 in contact with the top of the molding mold 203 moves to the right together, and under the rotation support of the front and rear two guide chains 303, multiple guide sprockets 302, and the guide shaft 301 on the guide chain 303, the front and rear two guide chains 303 rotate around the four guide sprockets 302, and drive the remaining multiple molding molds 401 to rotate together through the connection with the front and rear two guide chains 303. During the rotation, the molding mold 401 will drive the compression sleeve 403 to move together. When the compression sleeve 403 moves to the bottom of a raw material hopper 503 located on the left, the power motor 204 is turned off, and the multiple electromagnetic material valves 502 at the bottom of the left raw material hopper 503 are opened, and the food inside the raw material hopper 503 is The raw materials fall into the interior of the multiple compression sleeves 403 and the molding cavity 402 directly below through the multiple front and rear feeding tubes 501, and the food raw materials filled in the molding cavity 402 will not fall off under the support of the top of the conveyor belt 203. When the interior of the molding cavity 402 and the interior of the compression sleeve 403 are filled with food raw materials, the electromagnetic material valves 502 are closed to block the continued discharge of the raw material hopper 503, and the power motor 204 is started to make the conveyor belt 203 continue to run to the right, further causing the molding mold 401 and the compression sleeve 403 filled with food raw materials to move to the right together, until they move to the bottom of a fixed beam 604 at the left end, and then the power motor 204 is closed again. The conveyor belt 203 stops moving, and the lifting cylinder 601 is started, so that the output rod of the lifting cylinder 601 drives the pressure plate 602 to move downward, pushing the multiple pressure plates 603 in front and behind downward. The multiple pressure plates 603 move downward and abut against the tops of the multiple top plates 404 located at the bottom thereof, thereby pressing the top plates 404 downward. The downward pressing movement of the top plates 404 drives the compression sleeve 403 and the elastic airbag 406 fixed inside the compression sleeve 403 to move downward together. As the compression sleeve 403 moves downward, it slides into the inside of the forming cavity 402, causing the space formed by the compression sleeve 403 and the forming cavity 402 to shrink continuously, thereby squeezing the food raw materials located inside the compression sleeve 403 and the forming cavity 402 to make them initially formed. At the same time, when the top plate 404 moves downward, the return spring 405 is compressed, and the top plate 404 also drives the compressed air cylinder 408 to move downward along the inner wall of the annular air groove 4010, compressing the air inside the annular air groove 4010. The compressed air inside the annular air groove 4010 enters the interior of the blowing cavity 409 through the bottom of the blowing cavity 409, and is compressed from the top of the blowing cavity 409 to the area between the inner wall of the compressed air cylinder 408 and the outer wall of the compression sleeve 403, and then is transported to the interior of the elastic air bag 406 through the blowing hole 407, so that the deflated elastic air bag 406 gradually bulges, squeezes the outer wall of the formed food, and makes the outer wall of the food shrink to the middle by an appropriate amount. When the bottom of the compressed air cylinder 408 moves downward and contacts the annular After the top of the piston 4012 makes contact, as the compressed air cylinder 408 continues to move downward, the annular piston 4012 is pushed downward, causing multiple top springs 4013 to be compressed. When the annular piston 4012 moves to the bottom position of the pressure relief air channel 4011, the pressure relief air channel 4011 is connected to the interior of the blowing cavity 409 through the annular air groove 4010. At this time, the hollow elastic airbag 406 shrinks under the action of the rebound force and returns to the empty state, and the air inside the elastic airbag 406 is discharged into the area between the outer wall of the compression sleeve 403 and the inner wall of the compressed air cylinder 408 through the blowing hole 407 under the action of the rebound force of the elastic airbag 406, and then discharged into the area inside the annular air groove 4010 through the blowing cavity 409, and then to the The food is discharged outward, and then the lifting cylinder 601 is started to move its output rod upward to lift the pressure plate 602 and the pressure plate 603 upward, releasing the downward pressure on the top plate 404. The resilience of the return spring 405 pushes the top plate 404, the compression sleeve 403 and the elastic airbag 406 to move upward. Since the top plate 404 is deflated, its inner wall is separated from the outer wall of the food. Therefore, when the elastic airbag 406 moves upward, it will not carry the formed food upward, thereby facilitating the demoulding of the food. Then the power motor 204 is started again to make the conveyor belt 203 continue to rotate, and the food that has been preliminarily formed in the previous step is transported to the bottom of a raw material hopper 503 located at the right end. When the preliminarily formed food and the molding mold 401 move to the raw material hopper located on the right 503, the power motor 204 is closed again, and the electromagnetic material valves 502 located at the bottom of the right raw material hopper 503 are opened, so that the second raw material inside the raw material hopper 503 falls into the compression sleeve 403 at the bottom thereof through the feeding tube 501, that is, at the top of the preliminarily formed food. When the compression sleeve 403 is filled with the second raw material, the electromagnetic material valve 502 is immediately closed, and the power motor 204 is started. After the forming mold 401 filled with the second raw material is moved to the bottom of the fixed crossbeam 604 located on the right, the power motor 204 is closed, and the lifting cylinder 601 is started. The output rod of the lifting cylinder 601 moves downward, pushing the pressing plate 602 and the pressing plate 603 to move downward, squeezing the top plate 404 and the compression sleeve 403 downward.The second raw material is squeezed together with the food blank formed in the previous step, and then the lifting cylinder 601 is started to move its output rod upward to lift the pressing plate 602 and the pressing plate 603 upward, releasing the downward pressure on the top plate 404, and the rebound force of the return spring 405 pushes the top plate 404, the compression sleeve 403 and the elastic airbag 406 upward.
