Description

Technical Field

[0001] The invention belongs to the technical field of food machinery automation, in particular to an automatic forming machine for roasted bait blocks with an automatic picking-up component. Background Art

[0002] Shao'erkuai (roasted glutinous rice cake) is a traditional Chinese pastry beloved by consumers for its unique taste and diverse ways of serving. Traditionally, its production relies heavily on manual labor, including mixing the ingredients, pressing the dough, shaping the dough, and cleaning up the waste. However, this traditional manual production method presents numerous challenges, limiting its efficiency and quality, making it difficult to meet the demands of modern industrialized production and large-scale markets.

[0003] Traditional handmade production of shao kuai requires significant labor and time. From preparing the raw materials to shaping the final product, workers must perform each step individually, resulting in slow production and difficulty achieving continuous production. This inefficient method not only fails to meet the high demand for shao kuai in the modern market, but also leads to high production costs, limiting the large-scale development of the shao kuai industry.

[0004] During the manual production of roasted rice cakes, the thickness of the dough, the regularity of the shaping, and the precision of the cutting all rely on the workers' experience and operational skills. Due to the instability of manual operation, the thickness and shape of the roasted rice cakes are often difficult to maintain, and the product quality varies. This instability not only affects the appearance and taste of the roasted rice cakes, but may also cause problems such as sticking and breakage during subsequent processing or storage, further reducing the product's market competitiveness. Handmade roasted rice cakes require workers to perform long periods of high-intensity physical labor, especially during the dough pressing and shaping stages. This high-intensity labor not only easily leads to worker fatigue, but can also cause operational errors, affecting product quality and production efficiency. In addition, long periods of physical labor also have an adverse effect on workers' health, increasing the company's labor costs and management difficulties.

[0005] Therefore, those skilled in the art have proposed an automatic forming machine for roasted bait blocks with an automatic picking-up component to solve the problems raised in the background art. Summary of the Invention

[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] As attached Figure 1 To the attached Figure 6 As shown:

[0035] Embodiment 1: The present invention provides an automatic forming machine for roasted bait blocks with an automatic pick-up component, comprising:

[0036] A support frame 1, wherein two support plates 2 are provided on the upper end of the support frame 1. Two connecting shafts 4 are installed for relative rotation. The outer surfaces of the two connecting shafts 4 are both provided with pressing rollers 5.

[0037] A driving member 7 is installed at the lower end of the support frame 1. A driving shaft 8 is installed at the output end of the driving member 7. The driving shaft 8 is connected to the connecting shaft 4 through a transmission member 9.

[0038] Conveyor belt 10, wherein a rotating shaft 11 and a transmission rod 12 are rotatably mounted at both ends of the conveyor belt 10, and the rotating shaft 11 and the transmission rod 12 are both rotatably connected to the support frame 1, and the rotating shaft 11 is transmission-connected to the drive shaft 8 through a second transmission member 13;

[0039] A forming assembly, which is mounted on the upper end of the support frame 1 and is used to form the roasted bait blocks;

[0040] A recovery component is installed on the upper end of the support frame 1 and is used to pick up the waste of burnt bait blocks. The recovery component includes a connecting frame 30 installed on the upper end of the support frame 1. An active rod 31 and a driven rod 33 are rotatably installed at both ends of the connecting frame 30. Conveyor belts 32 are rotatably installed on the outer surfaces of the active rod 31 and the driven rod 33.

[0041] A feed hopper 3 is provided between the two support plates 2 , and the feed hopper 3 is located above the dough pressing roller 5 .

[0042] Two gears 6 are installed opposite to each other on one side of the support plate 2. The two gears 6 are respectively connected to one end of the two connecting shafts 4, and the two gears 6 are meshed.

[0043] The forming assembly includes two support plates 24 relatively mounted on the upper end of the support frame 1 , a shaft 25 is rotatably mounted between the two support plates 24 , a forming roller 26 is mounted on the outer surface of the shaft 25 , and a cutter 27 is provided on the outer surface of the forming roller 26 .

[0044] A second driving member 28 is installed at the upper end of the support frame 1 , and a fourth transmission member 29 is installed at the output end of the second driving member 28 , and the fourth transmission member 29 is in transmission connection with the shaft 25 .

[0045] A driving member 3 34 is installed at the lower end of the support frame 1 , and a transmission member 5 35 is provided at the output end of the driving member 34 , and the transmission member 5 35 is in transmission connection with the active rod 31 .

[0046] The driving member 1 7, the driving member 28 and the driving member 3 34 include but are not limited to motors.

[0047] Transmission member 1 9, transmission member 2 13, transmission member 4 29 and transmission member 5 35 all include but are not limited to chains and gears or pulleys and belts.

[0048] As can be seen above, the ingredients for the roasted rice cake are first added through the feed hopper 3. The feed hopper 3 is located above the two dough rollers 5. Its position allows the ingredients to fall smoothly between the rollers 5. Once the ingredients enter between the rollers 5, the drive element 7 begins to operate. The output end of the drive element 7 transmits power to the connecting shaft 4 via the drive shaft 8 and the transmission element 9. Since the connecting shaft 4 is connected to the dough rollers 5, the rollers 5 begin to rotate.

[0049] The two dough rollers 5 rotate in opposite directions, driven by two meshing gears 6 mounted on opposite sides of the support plate 2, thereby squeezing the raw material into a dough sheet of a certain thickness. This process is achieved through the relative rotation of the dough rollers 5, evenly pressing the raw material into a dough sheet, preparing it for the subsequent forming process.

[0050] After being squeezed by the dough roller 5, the dough sheet falls onto the conveyor belt 10. The rotating shaft 11 of the conveyor belt 10 is connected to the drive shaft 8 via the second transmission element 13. Therefore, when the first transmission element 7 is activated, the conveyor belt 10 also moves synchronously, conveying the dough sheet forward. As the conveyor belt 10 is transported, the dough sheet reaches the forming roller 26 of the forming assembly. The second transmission element 28 at the upper end of the support frame 1 is activated, and its output end transmits power to the shaft 25 through the fourth transmission element 29, thereby driving the forming roller 26 to rotate.

[0051] The outer surface of the forming roller 26 is provided with a cutter 27. During the rotation of the forming roller 26, the cutter 27 will cut the dough into the shape of the roasted bait block. Through the rotation of the forming roller 26 and the effect of the cutter 27, the dough is cut into pieces of roasted bait blocks, and the shape meets the requirements.

[0052] During the forming process, some waste materials of the burnt bait blocks are generated due to reasons such as cutting. The front end of the waste materials is placed on the conveyor belt 32. The driving member 3 34 at the lower end of the support frame 1 is activated, and its output end transmits power to the active rod 31 through the transmission member 5 35. The active rod 31 and the driven rod 33 are connected by the conveyor belt 32, so the conveyor belt 32 starts to move.

[0053] The movement direction of the conveyor belt 32 cooperates with the movement direction of the conveyor belt 10. The conveyor belt 32 continuously tears the waste apart from the formed roasted bait blocks, picks them up and transports them to the feed hopper 3. The formed roasted bait blocks are continuously transported forward by the conveyor belt 10 to the next process.

[0054] Through a highly efficient automated production process, the entire process, from raw material addition to forming, is fully automated. After being added from the feed hopper 3, the raw materials are sequentially squeezed by the dough rollers 5, transported by the conveyor belt 10, and cut and formed by the forming rollers 26, ultimately forming the roasted rice cakes. This integrated automated process not only significantly improves production efficiency, reduces the time and labor intensity of manual operations, but also avoids the errors and quality issues that can arise from manual operation.

[0055] The recycling component automatically collects waste generated during the molding process and transfers it to the feed hopper 3 for reuse. This process eliminates the need for manual waste removal, reducing raw material waste and production costs while also adhering to environmental protection and sustainable development principles. Timely waste recycling prevents waste accumulation within the machine, reducing the risk of equipment failure caused by waste accumulation and improving operational stability and reliability.

[0056] In addition, the operation of automated equipment reduces direct contact between operators and equipment, reducing operational risks. At the same time, the compact structure and reasonable layout of the equipment also make operation safer, reducing safety accidents caused by equipment failure or improper operation.

[0057] This automatic forming machine for roasted bait blocks has many advantages, such as efficient automated production, stable forming quality, waste recycling and reuse, and stable equipment operation. It has significantly improved the efficiency and quality of roasted bait block production and reduced production costs. At the same time, it meets the requirements of environmental protection and sustainable development and has significant economic and social benefits.

[0058] Example 2: This is the second embodiment of the present invention. An automatic forming machine for roasted bait blocks with an automatic picking component also includes an anti-sticking component, which is installed at the upper end of the support frame 1 and is used to prevent the roasted bait blocks from sticking. The anti-sticking component includes a fixed frame 14, which is installed at the lower end of the support frame 1. A rotating rod 15 is rotatably installed inside the fixed frame 14, and the rotating rod 15 is connected to the drive shaft 8 through a transmission member 16.

[0059] Eccentric wheels 17 are provided at both ends of the rotating rod 15, and a connecting rod 18 is installed at one end of each of the two eccentric wheels 17. A connecting frame 19 is rotatably installed on one side of the connecting rod 18, and a lifting rod 20 is installed on the upper end of the connecting frame 19. A guide frame 21 is provided on one side of the support frame 1, and a guide frame 21 is slidably installed inside the lifting rod 20. A fixed plate 22 is installed on the upper end of the lifting rod 20, and a screen bucket 23 is installed between the two fixed plates 22. Flour is placed inside the screen bucket 23, and a flour sprinkling net is provided at the bottom.

[0060] The driving parts 7 include but are not limited to motors,

[0061] The transmission parts 13 include but are not limited to chains and gears or pulleys and belts.

[0062] As can be seen from the above, when the driving member 1 7 is working, its power is transmitted to the rotating rod 15 through the driving shaft 8 and the transmission member 3 16. Eccentric wheels 17 are installed at both ends of the rotating rod 15, and the rotation of the eccentric wheel 17 drives the connecting rod 18 to reciprocate.

[0063] The reciprocating motion of connecting rod 18 is transmitted to lifting rod 20 via connecting frame 19, causing lifting rod 20 to reciprocate up and down under the guidance of guide frame 21. A fixed plate 22 is mounted on the upper end of lifting rod 20, and a screen hopper 23 is installed between the two fixed plates 22. Screen hopper 23 contains flour and has a flour sprinkling net at the bottom.

[0064] As the lifting rod 20 moves up and down, the flour in the screen hopper 23 is evenly sprinkled onto the surface of the roasted bait blocks on the conveyor belt 10 through the flour sprinkling net. This even distribution of flour effectively prevents the roasted bait blocks from becoming too wet and sticking to each other during subsequent processing or storage. This could cause the cutter 27 to stick, impacting subsequent processing efficiency, or the roasted bait blocks to stick to the upper surface of the conveyor belt 10, making it difficult to unload the material and causing damage, thereby reducing product quality. The drive element 7 is linked to other components to reduce production costs.

[0065] With driver 7 serving as the primary power source, power is transmitted to multiple components, including the dough roller 5, conveyor belt 10, and the anti-sticking assembly's rotating rod 15, via transmission components such as chains, gears, pulleys, and belts. This coordinated drive eliminates the need for separate drive devices, reducing energy consumption and production costs.

[0066] The linkage mechanism of the eccentric wheel 17, connecting rod 18, connecting frame 19, and lifting rod 20 allows the flour in the screen bucket 23 to be evenly sprinkled on the surface of the roasted bait blocks on the conveyor belt 10. This design effectively prevents the roasted bait blocks from sticking together during subsequent processing or storage due to excessive moisture, thus avoiding the deterioration of product quality caused by sticking.
