Description

Technical Field

[0001] This utility model relates to a food forming and processing machinery, and more particularly to a fully automatic food forming machine. Background Technology

[0002] The fast food industry requires rapid food forming, such as processing minced meat into various shapes of hamburgers and steaks. While existing food forming machines can process most general market-demanded products and offer the advantage of low cost, their overall structure still has some shortcomings. Current food forming machines generally use hydraulic filling of raw materials, which involves high pressure and can damage blocky materials, resulting in poor consistency in the shape and weight of the food. The punch in the demolding mechanism is controlled by a cylinder, limiting the frequency and accuracy of punch movement, easily leading to slow demolding and damage to the product's shape during demolding. The mold is made of plastic, which is easy to process into shapes, but produces burrs during demolding. The control system is far from meeting digital requirements. Furthermore, the limited structural and component precision restricts output. Utility Model Content

[0031] Preferably, the cam pump drive device is configured as a servo motor.

[0032] After adopting the above technical solution, the beneficial effects of this utility model are:

[0033] This invention relates to a food forming machine that uses a cam pump to deliver raw materials. The cam pump is driven by a servo motor, drawing in the raw materials and conveying them into the filling cavity of the filling seat assembly. This effectively reduces material compression and breakage. Furthermore, the bottom-up feeding method effectively prevents impact during feeding, reduces friction between the food material and the inner wall of the filling cavity, further minimizing material breakage and maximizing material integrity with high reliability. The cam pump pressure is also convenient and reliable to adjust, and a quantitative output of raw materials can be set, resulting in consistent weight of the formed food products and meeting the weight requirements of various product specifications. In addition, the absence of burrs during template forming and demolding ensures consistent food shape.

[0034] The venting and reflux plate assembly is equipped with an exhaust and material passage. The exhaust and material passage is mainly used to vent air during molding to prevent air bubbles in the food. In addition, the exhaust and material passage is also used to discharge the remaining residue after molding so that the residue can be recycled.

[0035] An air spring is installed between the bottom of the hopper and the frame. When the hopper needs to be cleaned, the air spring lifts the hopper and rotates and tilts it, which can thoroughly clean the hopper. It is hygienic, safe and has no dead corners, and is convenient for cleaning operations.

[0036] The filling head drive device includes a servo motor and an electric cylinder. The servo motor and electric cylinder drive the filling head to fill the filling cavity with raw materials. It can achieve high-precision positioning and upward movement, with high control accuracy. The electric cylinder has a simple structure, high reliability, and low maintenance cost. Moreover, it has a relatively smaller thrust than the traditional method of filling raw materials with hydraulic cylinders, avoiding damage to blocky raw materials.

[0037] A servo motor drives a crank to rotate, which in turn drives a connecting rod. The connecting rod pulls a guide rod to reciprocate linearly along a guide sleeve, thereby causing the template to slide back and forth between the forming and demolding positions. Because the template's movement is controlled by a servo motor, high repeatability and positioning accuracy are achieved. Each time, the template accurately reaches the forming position, ensuring the food forming holes are precisely filled and the food is formed. Simultaneously, each time, the template accurately reaches the demolding position, aligning the food forming holes with the punch of the demolding mechanism for easy demolding of the formed food. The optimized template motion design reduces ineffective motion and improves efficiency.

[0038] The punch of the demolding mechanism is driven by a servo motor, which enables the punch to be accurately aligned with the food forming hole on the template during demolding. This allows for quick, accurate, and reliable demolding. The high frequency of punch movement results in high demolding efficiency and, consequently, high production efficiency.

[0039] During each molding process, a small amount of food material inevitably remains in the filling cavity. This remaining material enters the return pipe of the material collection and recycling device through multiple vent holes on the vent plate, the vent grooves on the filling top plate, and the vertical holes. Once the remaining material accumulates to a certain amount, it will enter the hopper through the return pipe. This saves materials and avoids waste.

[0040] Furthermore, the template and filling plate are easy to disassemble and replace when the product type needs to be changed. Attached Figure Description

[0059] like Figure 1 and Figure 2The fully automatic food forming machine shown has a frame 1 equipped with a feeding device 2, a filling device 3, a template 4, a template moving mechanism 5, a demolding mechanism 6, a conveying mechanism 7, and an electrical control system. The template 4 has multiple food forming holes. The template 4 is preferably made of metal plate, which has the advantages of good wear resistance, avoids burrs on the product during demolding, has good forming effect, and minimizes material leakage, thus saving costs. A servo motor drives the linear motion of the template 4, ensuring high positional accuracy and high speed.

[0060] The feeding device 2 includes a hopper 201 and a screw conveyor 202. The screw conveyor 202 is horizontally arranged at the bottom of the hopper 201. The screw conveyor 202 includes a left-hand screw and a right-hand screw. The left-hand screw and the right-hand screw operate at the same speed and are both driven by a servo motor.

[0061] like Figure 4 and Figure 5 As shown, the filling device 3 includes a cam pump 301, a cam pump drive device 302, a filling seat assembly, a venting and return plate assembly, a filling head 305, and a filling head drive device 304. The cam pump drive device 302 drives the cam pump 301, and the cam pump drive device 302 is preferably a servo motor. The output shaft of the servo motor is connected to the cam pump 301 via a coupling.

[0062] The venting and reflux plate assembly is located above the filling seat assembly. There is a gap between the filling seat assembly and the venting and reflux plate assembly, allowing the template 4 to slide smoothly within the gap. The template moving mechanism 5 drives the template 4 to slide back and forth between the forming position and the demolding position.

[0063] The filling seat assembly has a filling cavity, and the filling head drive device 304 drives the filling head to move up and down reciprocally in the filling cavity. The venting and return plate assembly is provided with an exhaust and material passage.

[0064] When the template 4 is in the forming position, the filling cavity is connected to the food forming hole, and the venting and material passage is also connected to the food forming hole; the cam pump 301 is fixedly connected to the screw conveyor mechanism 202 and the filling seat assembly respectively through the material receiving pipe assembly.

[0065] The demolding mechanism 6 includes a punch assembly, a demolding drive device, and a transmission mechanism. The demolding drive device drives the transmission mechanism to move the punch assembly up and down reciprocally. When the template 4 is in the demolding position, the punch assembly moves downward to push the formed food through the food forming hole. The conveying mechanism 7 is located below the demolding mechanism 6 and carries away the formed food that falls from the demolding position. The conveying mechanism 7 is preferably a conveyor belt. Conveyor belts are existing technology and will not be described in detail here.

[0066] The feeding device 2, filling device 3, template moving mechanism 5, demolding mechanism 6, and conveying mechanism 7 are controlled by the electrical control system.

[0067] This invention utilizes a touchscreen and CPU processor, featuring a completely new user interface for human-machine interaction, multi-language input, convenient data adjustment, automatic data storage, fault diagnosis indication, and easy equipment maintenance and troubleshooting. The integration of a MES (Manufacturing Execution System) facilitates digital management of the equipment. Furthermore, it utilizes EtherCAT bus control for high-speed data communication.

[0068] Template 4 has a built-in chip, allowing the device to automatically read data and making it easy to operate. It boasts a high degree of automation, convenient and quick adjustments, accurate and reliable control, and high efficiency and productivity.

[0069] The screw conveyor mechanism 202 is driven by a servo motor, and preferably, the cam pump drive is also a servo motor. The servo motor drives the cam pump 301, which draws in the raw material and transports it to the filling cavity of the filling seat assembly, effectively reducing material crushing and breakage, and ensuring high reliability. Furthermore, the cam pump 301 has convenient and reliable pressure adjustment, can be set to output a fixed amount of raw material, and can meet the weight requirements of various product specifications.

[0070] like Figure 4 As shown, the filling seat assembly includes a filling seat 8 and a filling plate 9. The filling plate 9 is located on the filling seat 8 and the two are fixedly connected. The filling plate 9 and the filling seat 8 are fixedly connected by bolts. The filling seat 8 has a filling cavity 801, a filling seat feed channel 802 and a filling head guide hole 803. The filling seat feed channel 802 is connected to the filling cavity 801. The filling head guide hole 803 is located at the bottom of the filling seat 8 and is connected to the filling cavity 801. The filling plate 9 has a material passage hole 901. The filling cavity 801, the filling seat feed channel 802, the filling head guide hole 803 and the material passage hole 901 form the filling inner cavity. The material passage hole 901 connects the filling cavity 801 and the food forming hole. The filling head driving device 304 drives the filling head 305 to move up and down along the filling head guide hole 803.

[0071] The filling seat 8 has an upward-sloping feed channel 802. The inlet of the feed channel 802 is located on the side wall of the filling seat 8 near the bottom, and the outlet of the feed channel 802 is higher than its inlet and connected to the filling cavity 801. This means that the feeding process is from bottom to top, effectively preventing impact during feeding, reducing friction between the food material and the inner wall of the filling cavity 801, and further reducing material breakage.

The venting and material passage is mainly used for venting during molding to prevent air bubbles in the food. In addition, the venting and material passage is also used to discharge the remaining residue after molding so that the residual residue can be recycled.

[0074] like Figure 3 As shown, one bottom end of the hopper 201 is hinged to the frame 1. This hinge point is considered the rotation center of the hopper 201. A gas spring 12 is installed between the bottom of the hopper 201 and the frame 1. Both ends of the gas spring 12 are hinged to the frame 1 and the bottom of the hopper 201, respectively. The gas spring 12 can lift the hopper 201 and rotate it around its rotation center at a certain angle. A hopper tilting support block 1011 is fixedly installed on the frame 1. When the hopper 201 needs cleaning, the gas spring 12 lifts the hopper 201, causing it to rotate and tilt. The tilting support block 1011 supports the tilted hopper 201, allowing for thorough cleaning of the hopper 201, ensuring hygiene and safety without any blind spots.

[0075] like Figure 8 and Figure 9 As shown, the demolding mechanism 6 is mounted on the filling top plate 11 via the support frame 601. The punch assembly includes multiple punches 602 and a punch mounting plate 603. Multiple punches 602 are fixedly connected to the bottom of the punch mounting plate 603.

The eccentric disk 604 is fixedly connected to the output shaft of the second servo motor 600. The connecting rod 605 is located in the radial direction of the eccentric disk 604 and the two are fixedly connected. A mounting seat 6071 is fixed in the middle of the crossbeam 607. The mounting seat 6071 is connected to the connecting rod 605 through the spherical bearing 606. There are two guide shafts 609. The upper ends of the two guide shafts 609 are fixedly connected to both ends of the crossbeam 607, and the lower ends of the two guide shafts 609 are fixedly connected to the punch mounting plate 603. The guide seat 608 is fixed on the support frame 601.

[0077] The punch 602 of the demolding mechanism 6 is driven by a servo motor, which enables the punch 602 to be accurately aligned with the food forming hole on the template 4 during demolding, achieving quick demolding, accuracy and reliability. The punch moves at a high frequency, resulting in high demolding efficiency.

[0078] like Figure 1 As shown, the fully automatic food forming machine is equipped with a material collection and recycling device, which is a return pipe 14. The two ends of the return pipe 14 are connected to the filling top plate 11 and the hopper 201, respectively. The return pipe 14 is connected to the vertical hole 111 of the filling top plate 11.

[0079] During each molding process, a small amount of food material will inevitably remain in the filling cavity. The remaining food material enters the return pipe 14 of the material collection and recycling device through multiple vent holes 1001 on the vent plate 10, the vent groove 112 of the filling top plate 11, and the vertical hole 111. After the remaining food material accumulates to a certain amount, it will enter the hopper 201 through the return pipe.

[0080] like Figure 6 and Figure 7 As shown, the template moving mechanism 5 includes a third servo motor 501, a crank-connecting rod mechanism, a connecting beam 502, and a guide sliding mechanism. The third servo motor 501 is fixedly mounted on the frame 1. The crank-connecting rod mechanism includes a crank 503 and a connecting rod 504. The output end of the third servo motor 501 is fixedly connected to the crank 503. The crank 503 and one end of the connecting rod 504 are hinged through a crank shaft 5031. When the connecting rod 504 is long, multiple guide sleeves 506 can be set on each connecting rod.

[0081] The guide sliding mechanism includes two guide rods 505 and a guide sleeve 506. The guide sleeve 506 is fixedly connected to the frame 1, and the guide rods 505 are slidably connected to the corresponding guide sleeves 506.

[0082] Two guide rods 505 are arranged in parallel and fixed at both ends of the connecting beam 502. The connecting rod 504 is connected to the connecting beam 502 through a spherical bearing 606. The other end of the connecting rod 504 is connected to the transverse connecting rod through a spherical bearing 606. The two guide rods 505 are fixedly connected to the template 4. The ends of the two guide rods 505 are fixedly connected to the template mounting plate 5041. The template 4 and the template mounting plate 5041 are fixedly connected by bolts and nuts.

[0083] The third servo motor 501 drives the crank 503 to rotate, which in turn drives the connecting rod 504. The connecting rod 504 pulls the guide rod 505 to reciprocate linearly along the guide sleeve 506, thereby causing the template 4 to slide back and forth between the forming position and the demolding position. Because the movement of the template 4 is controlled by the servo motor, the repeatability and positioning accuracy are high. Each time, the template 4 accurately reaches the forming position, ensuring the food forming hole of the template is accurately filled and the food is formed. Simultaneously, each time, the template 4 accurately reaches the demolding position, aligning the food forming hole of the template with the punch 602 of the demolding mechanism 6, facilitating the demolding of the formed food. The optimized motion design of the template 4 reduces ineffective motion and improves efficiency. The linear reciprocating motion of the template, controlled by the servo motor, boasts high positional accuracy and high speed, reaching up to 120 times / minute, a leading level of performance.

[0084] like Figure 10 and Figure 11 As shown, the fully automatic food forming machine includes a lifting mechanism 13 for lifting the filling top plate 11. The lifting mechanism 13 includes a lifting drive device 131, two lifting guide shafts 132, and two lifting guide seats 133. The lifting guide shafts 132 are fixedly connected to both sides of the filling top plate 11. Specifically, connecting seats 134 are fixed to both sides of the filling top plate 11, and the top ends of the lifting guide shafts 132 are fixedly connected to the connecting seats 134. The two lifting guide shafts 132 can slide up and down on their respective lifting guide seats 133, which are fixed to the frame 1. The lifting drive device 131 is preferably a cylinder, and the end of the piston rod of the cylinder is hinged to the lifting guide shaft 132 through a spherical bearing.

[0085] The lifting mechanism 13 lifts the filling top plate 11 and the demolding mechanism 6 on it, freeing up space for easy replacement of the template 4 or for cleaning and maintenance. Changing product types requires disassembling and replacing the template 4 and the filling plate 9. Since the template 4 is fixedly connected to the template mounting plate 5041 with bolts and nuts, and the filling plate 9 and the filling seat 8 are fixedly connected with bolts, it is easy to replace the template and the filling plate, thus facilitating the change of product types.

[0086] The fully automatic food forming machine is also equipped with a water system, which uses water to rinse the template 4 and the food forming holes, making the template easy to demold and lubricating the template.

[0087] The working process of this fully automatic food forming machine is as follows:

[0088] Food ingredients are added to the hopper, and the screw conveyor 202 driven by a servo motor transports and mixes the ingredients. A cam pump 301 delivers the ingredients to the filling chamber 801 of the filling seat 8. Simultaneously, the template moving mechanism 5 drives the template 4 to the forming position, aligning the filling head with the food forming hole on the template. Since the filling head is located below the template 4, the servo motor drives the filling head 305 to move upwards along the filling head guide hole 803, punching the food ingredients into the food forming hole of the template and compacting them. Then, the filling head 305 moves downwards. Subsequently, the template moving mechanism 5 drives the template 4 to the demolding position, accurately aligning the punch 602 of the demolding mechanism 6 with the food forming hole on the template 4. The servo motor drives the punch 602 of the demolding mechanism 6 to move downwards, ejecting the formed food from the mold. The food falls onto the conveyor belt below and is transported to the next process. Then, the template moving mechanism 5 drives the template 4 back to the forming position for food forming, continuously performing the above forming and demolding cycle.

[0089] The various actions, amplitudes, and sequences of this fully automatic food forming machine are all automatically controlled by an electrical system. The raw materials that this fully automatic food forming machine can use include poultry (chicken, duck), seafood (fish, shrimp), livestock (pork, beef), and vegetables (potatoes, pumpkin, and other tubers). It can also use minced meat, whole chicken breasts, whole fish fillets, and shrimp. Spinach, other vegetables, and potatoes can also be used.

[0090] The fully automatic molding machine of this utility model uses a servo motor to drive the spiral conveyor mechanism 202, the cam pump 301 of the filling device 3, the filling head, and the template 4. The punch 602 of the demolding mechanism 6 is also driven by a servo motor, resulting in precise motion control and a high degree of automation.

[0091] This fully automatic forming machine can automatically complete the filling, forming, and output processes of food raw materials. It can be connected with a battering machine, flour coating machine, frying machine, steaming machine, quick-freezing machine, and packaging machine to form a fully automatic cooked food production line. It features high output and stable quality. Furthermore, product changeover is convenient, quick, and quantitatively accurate, effectively controlling production costs. Multiple molds are available for selection and replacement. It is suitable for forming meat, poultry, fish, shrimp, and other aquatic products, as well as potatoes, tubers, or vegetables. It is not only suitable for minced raw materials but also for forming various block-shaped products. It can produce hamburger patties, chicken nuggets, chicken strips, fish fillets, and other products. Meat products, after being cut, present a realistic meat block shape, easily gaining consumer acceptance and meeting market demand.

[0092] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
