Description

Technical Field

[0001] This utility model relates to the field of food production equipment, and in particular to a forming machine. Background Technology

[0002] Forming machines are commonly used mechanical equipment in the food production industry. Their basic function is to shape raw materials such as powders and slurries. Some forming machines work by drying the material, but these machines generally do not have heating or drying functions. Instead, the material is first shaped using a mold, then demolded and placed on a material rack to dry on its own, or transported by a conveyor to an oven or other curing or heating equipment for secondary processing to complete production. To complete all these processes in one operation, a large, fully automatic forming machine with heating, automatic conveying, automatic demolding, and pressing functions is required. This type of machinery is generally more expensive and is mostly used in non-food industrial production, such as the building materials industry, and is not suitable for food production where hygiene requirements are high. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a molding machine. The specific design scheme is as follows:

[0004] A molding machine includes a base frame in the shape of a "U". A base plate is mounted in the middle of the "U" shape of the base frame, and a mold is mounted in the middle of the base plate. A pressure plate is provided below the mold, and a material plate is provided on the top of the mold. An electric heating tube is provided below the base plate. A fan and an electric heating box are mounted on the base frame. The base plate has air holes. Air heated and dried by the electric heating box is driven by the fan and passes through the air holes to form a passage in the closed space formed by the base plate and the material plate, thereby performing drying, heating, and curing operations on the material loaded in the mold. The electric heating tube improves the heating efficiency of the material.

[0005] The mold is divided into multiple cavities, each containing a pressure block. A connecting rod connects the pressure block to the pressure plate. The pressure block fits into the mold cavity and can slide within the cavity along the axial direction of the connecting rod. Simultaneously, the pressure plate moves via the connecting rod. A base frame is located below the base plate. The base frame is a rectangular frame structure. The top and sides of the base frame abut against the bottom of the base plate and are fixed by hooks. Since the pressure plate moves during the molding process, the base frame serves to prevent the operator from getting their hand caught due to the pressure plate being close to the base plate, thus providing protection. It also provides a structural foundation for the installation of the heating element and prevents the heating element from burning the user. The base plate is connected to the base frame via the base frame.

[0006] The base frame has a base block, which is rotatably connected to the base frame via the base block. The center of the base block is a rectangular frame structure, and a bracket is provided at the bottom of one side of the base block. The bracket and the base block are integrally formed in one piece. The base frame is mounted on the bracket. One side of the rectangular frame structure of the base block is fixedly connected to the base frame, and the other end of the base block is fixedly connected to a drive shaft. The drive shaft is fixed to the base frame via a bearing seat. Based on the above structure, a structural basis is provided for the rotatable connection between the substrate and the base frame. The rotation of the substrate is driven by a motor, and the output shaft of the motor... The transmission shaft is fixed on the base frame and connected to the transmission wheel. The transmission wheel is also keyed to the transmission shaft. Speed ​​change is achieved by the difference in wheel diameter between different transmission wheels, thereby reducing the output speed. A shelf can be installed on the base frame to further reduce the speed by increasing the number of transmission shafts and transmission wheels. Alternatively, a motor with a speed reducer can be used to directly output a lower speed. The motor is installed in the base frame and sealed with a metal plate to improve its dustproof performance. The transmission wheel is a transmission pulley or a transmission sprocket, and the two transmission wheels that drive each other are connected by a transmission belt or transmission chain.

[0007] The base frame contains an electrical control box, which is electrically connected to the heating element, fan, and heating box. The electrical control box is also electrically connected to the sensor and motor. The sensor is used to sense the rotation angle of the substrate. Specifically, the sensor is a pressure sensor. The last transmission wheel used for transmission has two through holes symmetrically arranged along the center of the transmission wheel. The sensor probe abuts against the transmission wheel. When the transmission wheel rotates and the through hole coincides with the sensor probe, the sensor probe is embedded in the through hole. The sensor probe has a hemispherical structure so that when the transmission wheel continues to rotate, the sensor probe can be dislodged from the through hole.

[0008] The heating element is installed on the inner side wall of the rectangular frame structure of the base frame. The area of ​​the pressure plate is smaller than the inner area of ​​the base frame to prevent the pressure plate from hitting the heating element when it moves. A heat insulation layer can also be attached to the inner wall of the base frame, which can not only increase the heat preservation effect, but also prevent the side wall of the base frame from overheating due to heat transfer and burning the user.

[0009] The substrate is provided with a bent pipe below it. One end of the bent pipe is connected through a vent, and the other ends of the two bent pipes pass through the side wall of the base frame and the side wall of the base block and are respectively connected to the air outlet of the fan and the air outlet of the electric heating box.

[0010] The substrate and the material plate are fixed together by pressure strips and limiting strips. The side edges of the material plate are inclined outwards, and the cross-section of the material plate is trapezoidal. One side of the limiting strip is fixedly connected to the substrate, and the other end abuts against one side edge of the material plate. One side of the limiting strip is connected to one end of the rocker arm, and the other side abuts against the other side edge of the pressure plate. The other end of the rocker arm is connected to the cylinder shaft of the drive cylinder. The cylinder body of the drive cylinder is fixed to the substrate by a cylinder seat. There are multiple rocker arms, which are connected by a transmission rod. The multiple rocker arms are arranged in a linear array along the axial direction of the transmission rod. One of the rocker arms is connected to the drive cylinder. This structure ensures that the substrate provides support for the material plate when it is inverted, ensuring that the material can fall onto the material plate and preventing the material plate from falling.

[0011] The molding machine obtained by the above-described technical solution of this utility model has the following beneficial effects:

[0012] This allows small semi-automatic molding machines to have curing and drying functions without affecting the operating mechanism of the equipment, resulting in lower equipment modification and operating costs. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] A molding machine includes a base frame 1, which has a U-shaped structure. A base plate 2 is installed in the middle of the U-shaped structure of the base frame 1, and a mold 3 is installed in the middle of the base plate 2. A pressure plate 4 is provided below the mold 3, and a material plate 5 is provided on the top of the mold 3. An electric heating tube 6 is provided below the base plate 2. A fan 7 and an electric heating box 8 are installed on the base frame 1. The base plate 2 has air holes 9. Air that has been heated and dried by the electric heating box 8 is driven by the fan 7 and passes through the air holes 9 to form a passage in the closed space 10 formed by the base plate 2 and the material plate 5, thereby performing drying, heating, and curing operations on the material loaded in the mold 3. The electric heating tube 6 improves the heating efficiency of the material.

[0024] The mold 3 is divided into multiple cavities, each of which is equipped with a pressure block 11. A connecting rod 13 connects the pressure block 11 to the pressure plate 4. The outer part of the pressure block 11 fits into the mold cavity. The pressure block 11 can slide along the axial direction of the connecting rod 13 within the mold cavity, and simultaneously move the pressure plate 4 via the connecting rod 13. A base frame 12 is provided below the base plate 2. The base frame 12 is a rectangular frame structure. The top and four sides of the base frame 12 abut against the bottom of the base plate 1 and are fixed by hooks 31. Since the pressure plate 4 will move during the molding process, the base frame 12 serves to prevent the operator from getting their hand caught due to the pressure plate 4 being close to the base plate 2 during operation, thus providing protection. It also provides a structural foundation for the installation of the heating tube 6 and prevents the heating tube from burning the user. At the same time, the base plate 2 is connected to the base frame 1 through the base frame 12.

[0025] The base frame 1 is provided with a base block 14, and the base frame 1 is rotatably connected to the base frame 12 through the base block 14. The middle part of the base block 14 is a rectangular frame structure, and a bracket 15 is provided on one bottom side of the base block 14. The bracket 15 and the base block 14 are integrally formed in one piece. The base frame 12 is mounted on the bracket 15. One side of the rectangular frame structure of the base block 14 is fixedly connected to the base frame 12, and the other end of the base block 14 is fixedly connected to the drive shaft 16. The drive shaft 16 is fixed to the base frame 1 through a bearing seat. Based on the above structure, a structural basis is provided for the rotatable connection between the base plate 2 and the base frame 1. The rotation of the base plate 2 is driven by a motor 17. The output shaft of 7 is connected to the transmission wheel 18, and the transmission shaft 16 is fixed on the base frame 1. The transmission wheel 18 is also keyed and installed on the transmission shaft 16. The speed is changed by the difference in wheel diameter between different transmission wheels 18, and the output speed is reduced. A shelf 19 can be installed on the base frame 1 to further reduce the speed by increasing the number of transmission shafts 16 and transmission wheels 18. Alternatively, a motor 17 with a reducer 20 can be used to directly output a lower speed. The motor 17 is installed in the base frame 1 and its dustproof performance is improved by sealing it with a metal plate. The transmission wheel 18 is a transmission belt pulley or a transmission sprocket. The two transmission wheels 18 that drive each other are connected by a transmission belt 32 or a transmission chain.

[0026] The base frame 1 is equipped with an electrical control box 21, which is electrically connected to the heating element 6, the fan 7, and the heating box 8. The electrical control box 21 is also electrically connected to the sensor 22 and the motor 17. The sensor 22 is used to sense the rotation angle of the substrate 2. Specifically, the sensor 22 is a pressure sensor. The last transmission wheel 18 used for transmission has two through holes 23 symmetrically arranged along the center of the transmission wheel 18. The probe of the sensor 22 abuts against the transmission wheel 18. When the transmission wheel 18 rotates and the through hole 23 coincides with the probe of the sensor 22, the probe of the sensor 22 is embedded in the through hole 23. The probe of the sensor 22 has a hemispherical structure so that when the transmission wheel 18 continues to rotate, the probe of the sensor 22 can be dislodged from the through hole 23.

[0027] The heating element 6 is installed on the inner side wall of the rectangular frame structure of the base frame 12. The area of ​​the pressure plate 4 is smaller than the inner area of ​​the base frame 12 to prevent the pressure plate 4 from hitting the heating element 6 when it moves. A heat insulation layer 24 can also be attached to the inner wall of the base frame 12, which can not only increase the heat preservation effect, but also prevent the side wall of the base frame 12 from overheating due to heat transfer and scalding the user.

[0028] The base plate 2 is provided with a bent pipe 25 below it. One end of the bent pipe 25 is connected through the air hole 9. The other ends of the two bent pipes 25 pass through the side wall of the base frame 12 and the side wall of the base block 14 and are respectively connected to the air outlet of the fan 7 and the air outlet of the electric heating box 8.

[0029] The substrate 2 and the material plate 5 are fixed together by pressure strips 26 and limiting strips 27. The side edges of the material plate 5 are inclined outwards, and the cross-section of the material plate 5 is trapezoidal. One side of the limiting strip 27 is fixedly connected to the substrate 2, and the other end abuts against one side edge of the material plate 5. One side of the limiting strip 27 is connected to one end of the rocker arm 28, and the other side abuts against the other side edge of the pressure plate 5. The other end of the rocker arm 28 is connected to the cylinder shaft of the drive cylinder 29. The cylinder body of the drive cylinder 29 is fixed to the substrate 2 by a cylinder seat. There are multiple rocker arms 28, which are connected to each other by transmission rods 30. The multiple rocker arms 28 are arranged in a linear array along the axial direction of the transmission rods 30. One of the rocker arms 28 is connected to the drive cylinder 29. This structure ensures that the substrate 2 provides support for the material plate 5 when it is inverted, ensuring that the material can fall onto the material plate 5 and preventing the material plate 5 from falling.

[0030] The equipment's flipping mechanism:

[0031] When the user presses the pedal 33, the electrical control box 21 controls the motor 17 to start. The motor 17 drives the base plate 2 to rotate through the transmission wheel 18, transmission belt 32, and base block 14, thus achieving the flipping of the base plate 2. When the base plate 2 is fully flipped 180°, the probe of the sensor 22 is just stuck in the through hole 23. At this time, the electrical control box 21 stops. When the base plate 2 needs to be reset, the user presses the pedal 33 and starts the motor 17 again. After the base plate 2 is reset, the probe of the sensor 22 is just stuck out of the other through hole 23. The sensor 22 sends a signal, and the electrical control box 21 controls the motor 17 to stop.

[0032] Demolding mechanism:

[0033] When the substrate 2 is damaged, the pressure plate 4 and the pressure block 11 will slide downward along the mold cavity of the mold 3 based on their own weight, pushing the material out of the mold 3. When the substrate 2 is reset, the pressure plate 4 and the pressure block 11 will reset again based on gravity.

[0034] Heating mechanism:

[0035] The electric heating box 8 and the fan 7 are started by the electric control box 21. After the electric heating box 8 heats the air, the air is drawn out of the closed space 10 based on the negative pressure generated by the fan 7. The dry hot air enters the closed space 10 from the electric heating box 8 through the bend pipe 25 and the air hole 9, and is finally discharged from the fan 7 through the bend pipe 25.

[0036] The heating element 6 is activated by the heating box 21. The heating element 6 heats the surrounding air. Since the heating element 6 is located on both sides of the mold 3, the mold 3 is heated by heat transfer.

[0037] Operating steps:

[0038] The user first loads material into mold 3, then covers it with material plate 5, making one side of it abut against limit strip 27. Then, the user steps down pedal 33 to start drive cylinder 29. Drive cylinder 29 drives rocker arm 28 to rotate, eventually causing pressure strip 26 to press down on the other end of material plate 5 to achieve fixation. Then, when the user steps down pedal, mold 3 flips over, and the material is demolded by pressure block 11, causing the formed material to fall onto material plate 5. At this time, the user holds material plate 5 by hand or with a turnover cart or material rack. Then, the user starts drive cylinder 29 to reset its cylinder shaft and removes material plate 5 and the formed material on material plate 5 from one side of pressure strip 26.

[0039] If heating and drying or cooking are required during the above process, the heating element 6, fan 7, and heating box 8 can be activated to achieve the drying or cooking function.

[0040] The overall equipment is small in size and simple in structure. The design of the base block 14 provides space for the installation of the fan 7 and the electric heating box 8 without changing the flipping mechanism. The base frame 12 provides a structural foundation for the connection of the base block 14 and the installation of the electric heating tube 6. Finally, the semi-automatic molding machine can be modified by punching holes 9 on the base plate 2. The modification cost and operating cost of the equipment are low, and the equipment is small in size. Compared with large molding machines, the cost of creating a sterile production environment is lower, making it more suitable for the food production field.

[0041] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
