[0033] The molding component 4 includes a molding die 401, which is fixedly installed between the guide chains 303 distributed front and back. One side of the molding die 401 is penetrated with a plurality of molding circular cavities 402 distributed front and back. A compression circular sleeve 403 is slidably installed inside the compression circular sleeve 403, a top flap 404 is fixedly installed on the top of the outer wall of the compression circular sleeve 403, a reset spring 405 is fixedly installed between the bottom of the top flap 404 and the top of the molding die 401, and the reset spring 405 is located on the periphery of the compression circular sleeve 403.

[0034] Two left-right distributed raw material buckets 5 are fixedly installed inside the frame 1. The raw material buckets 5 are located inside the two front and rear guide chains 303. A plurality of front-back distributed feeding tubes 501 are fixedly installed at the bottom of the raw material bucket 5. The positions of the feeding tubes 501 are adapted to the positions of the forming circular cavities 402. Two left-right distributed fixed beams 6 are fixedly installed inside the frame 1. The fixed beams 6 and the raw material buckets 5 are alternately distributed in sequence. An electric cylinder 601 is fixedly installed at the bottom of the fixed beam 6. A connecting guide bar 602 is fixedly installed at the bottom of the output rod of the electric cylinder 601. A plurality of front-back distributed pressure plates 603 are fixedly installed at the bottom of the connecting guide bar 602. The positions of the plurality of pressure plates 603 correspond to the positions of the plurality of forming circular cavities 402 one by one. Electromagnetic material valves 502 are fixedly installed at the bottom of the feeding tubes 501. 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.

[0035] 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 rotational support of the guide chains 303, the guide sprockets 302 and the guide shaft 301, the front and rear guide chains 303 rotate around the four guide sprockets 302, and drive the remaining multiple forming molds 401 to rotate together through the connection with the front and rear 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 5 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 5 are opened. The food raw materials located inside the raw material hopper 5 fall into the interior of the multiple compression sleeves 403 and the forming circular cavity directly below it through the front and rear multiple feeding tubes 501. The interior of the forming circular cavity 402 is supported by the top of the conveyor belt 203, and the food raw materials filled in the forming circular cavity 402 will not fall down. When the interior of the forming circular cavity 402 and the interior of the compression circular sleeve 403 are filled with food raw materials, the electromagnetic material valve 502 is closed to block the continued feeding of the raw material bucket 5, and the power motor 204 is started to make the conveyor belt 203 continue to run to the right, further causing the forming mold 401 filled with food raw materials and the compression circular sleeve 403 to move to the right together, until they move to the bottom of a fixed crossbeam 6 at the left end, and then the power motor 204 is closed again, the conveyor belt 203 stops moving, and then the electric cylinder 601 is started, so that the output rod of the electric cylinder 601 drives the connecting guide bar 602 to move downward The plurality of pressure plates 603 at the front and rear are pushed downward, and the plurality of pressure plates 603 move downward and abut against the tops of the plurality of top flip plates 404 at the bottom thereof, thereby pressing the top flip plates 404 downward. The downward pressing movement of the top flip 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 interior of the forming circular cavity 402, causing the space formed by the compression sleeve 403 and the forming circular cavity 402 to shrink continuously, thereby squeezing the food raw materials inside the compression sleeve 403 and the forming circular cavity 402 to give them a preliminary shape. Subsequently, the electric cylinder 601 is started to move its output rod upward to lift the connecting strip 602 together with the pressure plate 603 upward.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 conveyed to the bottom of a raw material hopper 5 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 5 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 5 are opened to allow the second raw material inside the raw material hopper 5 to fall into the compression sleeve 403 at the bottom thereof through the feeding tube 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 6 located on the right, the power motor 204 is turned off and the electric cylinder 601 is started. The output rod of the electric cylinder 601 moves downward, pushing the connecting strip 602 and the pressure plate 603 downward, squeezing the top flip plate 404 and the compression sleeve 403 downward, so that the second raw material and the food blank formed in the previous step are squeezed together. Then the electric cylinder 601 is started, so that its output rod moves upward to lift the connecting strip 602 and the pressure plate 603 upward, and the downward pressure on the top flip plate 404 is released. The resilience of the return spring 405 pushes the top flip plate 404, the compression sleeve 403 and the elastic airbag 406 upward.

[0036] In the second embodiment, a side of the molding die 401 close to the top flap 404 is provided with an annular air groove 4010, the annular air groove 4010 is located at the periphery of the molding circular cavity 402, a compressed air cylinder 408 is slidably installed inside the annular air groove 4010, the top of the compressed air cylinder 408 is fixedly connected to the bottom of the top flap 404, a blowing cavity 409 is provided inside the compressed air cylinder 408, the blowing cavity 409 penetrates the bottom of the compressed air cylinder 408 and the inner wall of the compressed air cylinder 408, a blowing hole 407 is penetrated through the upper part of the inner wall of the compression sleeve 403, the position of the blowing hole 407 corresponds to the position of the blowing cavity 409, 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;

[0037] 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 pressure relief air passage 4011 is penetrated through the inner wall of the annular air groove 4010 away from the compression sleeve 403, and the pressure relief air passage 4011 is located at the bottom of the annular piston 4012;

[0038] Specifically, the output rod of the electric cylinder 601 drives the connecting guide bar 602 to move downward, pushing the front and rear multiple pressure plates 603 downward, and the multiple pressure plates 603 move downward and abut against the tops of the multiple top flip plates 404 located at the bottom thereof, thereby pressing the top flip plates 404 downward. The downward pressing movement of the top flip 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 chamber through the bottom of the blowing chamber 409. After the food is inside the cavity 409, it 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 transported to the inside of the elastic air bag 406 through the blowing hole 407, so that the deflated elastic air bag 406 is gradually hollowed out, and the outer wall of the formed food is squeezed to shrink the outer wall of the food toward the middle by an appropriate amount. When the bottom of the compressed air cylinder 408 moves downward and contacts the top of the annular piston 4012, as the compressed air 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 gas 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 gas groove 401 through the blowing cavity 409. 0, and then discharged outwardly through the pressure relief air channel 4011, and then the electric cylinder 601 is started to move its output rod upward to lift the connecting guide bar 602 and the pressure plate 603 upward, so as to release the downward pressure on the top flip plate 404, and the resilience of the return spring 405 pushes the top flip plate 404, the compression sleeve 403 and the elastic airbag 406 to move upward. Since the top flip 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.

[0039] Embodiment 3: The diameter of the pressure plate 603 is larger than the inner diameter of the compression sleeve 403;

[0040] 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 flap 404 to push the top flap 404 together with the compression sleeve 403 downward.

[0041] 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;

[0042] 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.

[0043] In the present scheme, a belt-type forming machine for pancake-shaped food is operated by starting a 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 another conveying shaft 201 and a 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, and because 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 conveying belt 203 to rotate. The molding dies 401 in contact with each other at the top move rightward 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 dies 401 to rotate together through the connection with the front and rear two guide chains 303. During the rotation, the molding dies 401 will drive the compression sleeve 403 to move together. When the compression sleeve 403 moves to the bottom of a raw material hopper 5 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 5 are opened. The food raw materials located in the raw material hopper 5 pass through the front and rear multiple feeding valves. The material tube 501 falls into the interior of the multiple compression sleeves 403 and the molding circular cavity 402 directly below it, and under the supporting effect of the top of the conveyor belt 203, the food raw materials filled in the molding circular cavity 402 will not fall off. When the interior of the molding circular cavity 402 and 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 5, 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 6 at the left end, and then the power motor 204 is closed again, and the conveyor belt 203 stops moving. Then the electric cylinder 601 is started, so that the output rod of the electric cylinder 601 drives the connecting guide bar 602 to move downward, pushing the front and rear multiple pressure plates 603 downward, and the multiple pressure plates 603 move downward and abut against the tops of the multiple top flip plates 404 located at the bottom thereof, thereby pressing the top flip plates 404 downward. The downward pressing movement of the top flip 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 inside of the forming circular cavity 402, causing the space formed by the compression sleeve 403 and the forming circular cavity 402 to shrink continuously, thereby squeezing the food raw materials located inside the compression sleeve 403 and the forming circular cavity 402 to make them initially formed;

[0044] At the same time, when the top flap 404 moves downward, the return spring 405 is compressed, and the top flap 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 causes the outer wall of the food to shrink toward the middle by an appropriate amount. When the bottom of the compressed air cylinder 408 After moving downward and contacting the top of the annular piston 4012, 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 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 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. The air is discharged outwards through the pressure relief air channel 4011, and then the electric cylinder 601 is started to move its output rod upward to lift the connecting guide bar 602 and the pressure plate 603 upwards, thereby releasing the downward pressure on the top flap 404. The resilience of the return spring 405 pushes the top flap 404, the compression sleeve 403 and the elastic air bag 406 to move upwards. Since the top flap 404 is deflated, its inner wall is separated from the outer wall of the food. Therefore, when the elastic air bag 406 moves upward, it will not carry the formed food upwards, 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 conveyed to the bottom of a raw material hopper 5 located at the right end. When the preliminarily formed food and After the forming mold 401 moves to the bottom of the raw material hopper 5 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 5 are opened, so that the second raw material inside the raw material hopper 5 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 6 located on the right, the power motor 204 is closed, and the electric cylinder 601 is started. The output rod of the electric cylinder 601 moves downward, pushing the guide bar 602 and the pressure plate 603 to move downward.The top flip plate 404 and the compression sleeve 403 are pressed downwards to squeeze the second raw material together with the food blank formed in the previous step, and then the electric cylinder 601 is started to move its output rod upward to lift the connecting guide bar 602 and the pressure plate 603 upwards, and the downward pressure on the top flip plate 404 is released. The rebound force of the return spring 405 pushes the top flip plate 404, the compression sleeve 403 and the elastic airbag 406 to move upwards.
