Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a food weighing and packaging integrated machine, including a packaging table 1, a drive chamber 3 fixedly connected to the front end of the lower surface of the packaging table 1, a sealing machine 6 provided at the front end of the upper surface of the packaging table 1, a controller 22 provided on the right side of the packaging table 1, the input end of the sealing machine 6 being electrically connected to the output end of the controller 22, the input end of the controller 22 being electrically connected to an external power supply, and also includes a lifting mechanism 4; Lifting mechanism 4 includes a sliding plate 41, connecting rod 42, sliding rod 43, sliding seat 44, lifting frame 45, drive shaft 46, drive handle 47, and connecting column 48. The sliding plate 41 is slidably connected to the front and rear ends between the packing table 1 and the drive compartment 3. The left and right ends of the sliding plate 41 are rotatably connected to the connecting rod 42. The middle of two horizontally adjacent connecting rods 42 are rotatably connected to the same connecting shaft. The left and right ends of the lifting frame 45 are fixedly connected to the sliding rod 43. The front and rear ends of the outer surface of the sliding rod 43 are slidably connected to the sliding seat 44. The lower end of the sliding seat 44 is rotatably connected to the upper end of the vertically adjacent connecting rod 42. The four corners of the lower surface of the lifting frame 45 are... The guide column 5 is fixedly connected. The front end of the upper surface of the packing table 1 is provided with four sliding openings. The inside of each sliding opening is slidably connected to the outer surface of the vertically adjacent guide column 5. A laser rangefinder sensor 2 can be set at the right end of the lifting frame 45. The laser rangefinder sensor 2 can be DT35-B15551. The laser rangefinder sensor 2 is bidirectionally electrically connected to the controller 22. The controller 22 controls the operation of the laser rangefinder sensor 2 using methods commonly used in the prior art to realize the real-time distance between the upper surface of the packing table 1 and the laser probe of the laser rangefinder sensor 2, thereby obtaining the real-time position status of the sealing machine 6, which facilitates the accurate adjustment of the vertical position of the sealing machine 6 by personnel. The drive shaft 46 is rotatably connected to the upper end of the drive chamber 3. The upper end of the drive shaft 46 is fixedly connected to the drive handle 47. The front and rear ends of the upper surface of the drive handle 47 are fixedly connected to the connecting column 48. The middle part of the sliding plate 41 is provided with a clearance groove. The connecting column 48 is slidably connected to the adjacent clearance groove. The lifting mechanism 4 also includes a motor 49. The motor 49 is located at the front end of the top wall of the drive chamber 3. The right end of the output shaft of the motor 49 is fixedly connected to the worm. The lower end of the drive shaft 46 is fixedly connected to the worm wheel. The worm wheel and the worm are meshed and connected. The worm wheel and the worm are both located inside the drive chamber 3. External impurities will not affect the transmission efficiency of the worm wheel and the worm. The input terminal of motor 49 is electrically connected to the output terminal of controller 22. Based on the actual thickness of the food to be packaged, controller 22 controls the operation of motor 49. The rotation of the output shaft of motor 49 drives the worm gear, which in turn drives the worm wheel, which in turn drives the drive shaft 46. The drive shaft 46 then drives the drive handle 47, causing both connecting posts 48 to rotate around the central axis of the drive shaft 46. During rotation, the connecting posts 48 slide within their corresponding clearance grooves. Simultaneously, each connecting post 48 pushes the adjacent sliding plate 41 towards the center of the drive compartment 3. The relative movement of the two sliding plates 41 causes the lower ends of the adjacent connecting rods 42 to move towards the center of the drive compartment 3. A connecting shaft is rotatably connected to the middle of each of the two adjacent connecting rods 42. Under the rotational support of the connecting shaft, the upper end of each connecting rod 42 moves towards the center of the drive chamber 3, thereby causing the sliding seat 44 to slide on the outer surface of the corresponding sliding rod 43 towards the center of the drive chamber 3. At the same time, it pushes the lifting frame 45 to move upward, and the guide column 5 slides inside the corresponding sliding opening, providing guidance and limiting for the vertical movement of the lifting frame 45, preventing the lifting frame 45 from shaking during the lifting process, and thus ensuring the stability of the position adjustment of the sealing machine 6. When the sealing machine 6 reaches the required height, the controller 22 shuts off the motor 49. The self-locking performance of the worm gear and worm ensures the stable support of the connecting rod 42 for the lifting frame 45. The packaging table 1 has an unwinding frame 8 at its front, with an unwinding roller 9 rotatably connected to its upper end. A second motor 10 is mounted on the upper right side of the unwinding frame 8, with its output shaft fixedly connected to the right end of the unwinding roller 9. The input of the second motor 10 is electrically connected to the output of the controller 22. Symmetrically distributed guide plates 7 are located at the front end of the upper surface of the packaging table 1. The controller 22 drives the second motor 10, and the rotation of its output shaft causes the unwinding roller 9 to rotate, thus unwinding the packaging film. Under the action of an external traction device, the packaging film is unwound by the unwinding roller 9. After being rolled up, the packaging film moves backward under the guidance of two guide plates 7. The middle part of the packaging film adheres to the upper surface of the electric conveyor belt 19. The food being transported is located in the middle of the upper surface of the packaging film. At the same time, the left and right sides of the packaging film are folded inward under the guidance of the corresponding guide plates 7. Then, when the packaging film passes through the sealing port of the sealing machine 6, the controller 22 enables the sealing machine 6 to run. The heater at the sealing port of the sealing machine 6 is activated, and the edges of the packaging film are squeezed, so that the heated and melted packaging film sticks together. Meanwhile, the packaging film and the food continue to move backward under the conveying action of the electric conveyor belt 19 at the front. Wherein: A support frame 2 is set at the center of the upper surface of the packaging table 1. Monitoring cameras can be set at both the front and rear ends of the support frame 2. The monitoring cameras can be LA-GM-02K08A line scan industrial cameras. Both monitoring cameras are bidirectionally electrically connected to the controller 22. The controller 22 controls the operation of the monitoring cameras using methods commonly used in the prior art. The monitoring cameras take pictures and record the position status of the food in real time and transmit the image information to the signal receiving end of the controller 22 in real time. The controller 22 compares the image information with the standard position information of the food that can be cut, and uses this information to control the operation status of the electric push rod 13 and the two electric conveyor belts 19 on the front side. Guide rods 12 are slidably connected to both ends of the support frame 2. The lower ends of the two guide rods 12 are fixedly connected to the lifting plate 11. During the vertical movement of the lifting plate 11, the guide rods 12 slide inside the corresponding circular openings to provide sliding support for the lifting plate 11. At the same time, the extension end of the electric push rod 13 is prevented from being subjected to a force perpendicular to the axial direction, thereby preventing the extension end of the electric push rod 13 from being deformed by force and affecting its own transmission effect. A heating seat 15 is provided at the front end of the lower surface of the lifting plate 11. A heating resistance wire is provided at the lower end of the heating seat 15 to heat the lower surface of the heating seat 15. A cutting blade 16 is provided at the rear end of the lower surface of the lifting plate 11. A support plate is fixedly connected to the middle of the packing table 1. An electric push rod 13 is provided at the middle of the upper surface of the support frame 2. The telescopic end of the electric push rod 13 is fixedly connected to the middle of the upper surface of the lifting plate 11. A laser range sensor 14 is provided at the right end of the upper surface of the support frame 2. The laser range sensor 14 is bidirectionally electrically connected to the controller 22. During the vertical movement of the lifting plate 11, the controller 22 enables the laser range sensor 14 to operate. The laser probe of the laser range sensor 14 emits laser light towards the upper end of the lifting plate 11. The laser beam reaches the upper end of the lifting plate 11 and is reflected back to the laser probe of the laser range sensor 14. Based on the speed of light and the time it takes for the laser to reflect back to the laser probe, the distance between the upper surface of the lifting plate 11 and the laser probe of the laser range sensor 14 is monitored in real time. The laser range sensor 14 sends the distance information to the signal receiving end of the controller 22 in real time to ensure that the movement of the lifting plate 11 does not exceed the specified stroke, thereby preventing the vertical movement of the heating seat 15 and the cutting blade 16 from exceeding the specified stroke. The input end of the electric push rod 13 is electrically connected to the output end of the controller 22. When the food reaches the front of the support plate, the controller 22 shuts off the electric conveyor belt 19 and activates the electric push rod 13. The telescopic end of the electric push rod 13 extends, pushing the lifting plate 11 downward. The downward movement of the lifting plate 11 causes the heating seat 15 and the cutting blade 16 to move downward. Simultaneously, the controller 22 energizes the heating resistance wire at the lower end of the heating seat 15. The energized heating resistance wire generates heat and transfers the heat to the lower surface of the heating seat 15. When the lower surface of the heating seat 15 contacts the packaging film, the upper and lower layers of the packaging film are thermally bonded. At the same time, the cutting blade 16, supported by the support plate, cuts the packaging film. After cutting, the controller... 22 retracts the telescopic end of the electric push rod 13, thereby driving the lifting plate 11 to move upward. The upward movement of the lifting plate 11 drives the heating seat 15 and the cutting blade 16 to move upward, waiting for the next sealing and cutting. At this time, the controller 22 enables the two electric conveyor belts 19 on the front side to run, conveying the packaging film and food backward. When the food in the packaging film reaches the designated position of the electric conveyor belt 19 on the rear side, the controller 22 shuts off the electric conveyor belt 19 and enables the electric push rod 12 to run again, performing heat sealing and cutting of the packaging film on the front side of the food, thereby achieving the sealing and packaging of the food. This cycle is repeated for packaging each food item. The packaging platform 1 has sliding grooves 17 on both the left and right rear ends of its surfaces. Two fixed posts 20 are fixedly connected inside each sliding groove 17. A weighing frame 18 is slidably connected between the two sliding grooves 17. Two guide ports are provided at both ends of the weighing frame 18, and these guide ports are slidably connected to the outer surfaces of adjacent fixed posts 20. A weighing sensor 21 is installed between the rear end of the packaging platform 1 and the lower end of the weighing frame 18. The weighing sensor 21 is bidirectionally electrically connected to the controller 22. The weighing frame 18 transmits the weight of the packaged food to the elastic diaphragm of the weighing sensor 21. The controller 22 activates the weighing sensor 21, causing the elastic diaphragm to deform proportionally to the pressure. This deformation causes the weighing sensor 21 to operate via a piezoresistive bridge. When the four resistance values ​​change, the bridge becomes unbalanced, and the output voltage signal is proportional to the pressure. The differential amplifier, built-in temperature sensor, and compensation algorithm inside the weighing sensor 21 amplify and process the voltage signal in sequence, and convert the analog voltage signal into a digital signal through the A / D converter of the weighing sensor 21. Finally, the digital pressure signal is sent to the signal receiving end of the controller 22 in real time. The controller 22 records the weight of the weighed food. After the weighing is completed, the controller 22 starts the electric conveyor belt 19 at the last side to transport the weighed food to the next working area and transport the new food to be weighed to the middle of the weighing rack 18 for the next weighing. Among them, electric conveyor belts 19 are installed at both ends of the packaging table 1 and the middle of the weighing frame 18. The input ends of the three electric conveyor belts 19 are electrically connected to the output end of the controller 22. The controller 22 realizes the operation of the two electric conveyor belts 19 at the front. The external conveying equipment conveys the food to be protected to the front end of the electric conveyor belt 19 at the front. Under the conveying action of the electric conveyor belt 19 at the front, the food moves from front to back.

[0016] The working principle of the integrated food weighing and packaging machine provided by this utility model is as follows: During operation, the operator first places the packaging table 1, support frame 2, and other mechanisms stably in the horizontal working area. After stable placement, the operator, according to the actual thickness of the food to be packaged, uses the controller 22 to activate the motor 49. The output shaft of the motor 49 rotates, driving the worm gear to rotate. The worm gear rotates, driving the worm wheel to rotate. The worm wheel rotates, driving the drive shaft 46 to rotate. The drive shaft 46 rotates, driving the drive handle 47 to rotate. This causes both connecting columns 48 to rotate around the central axis of the drive shaft 46. During the rotation of the connecting columns 48, they slide within the corresponding clearance grooves. Simultaneously, the connecting columns 48 move the adjacent sliding plates 41 towards the center of the drive chamber 3. The movement of the two sliding plates 41 towards each other causes the lower ends of the adjacent connecting rods 42 to move closer to the center of the drive chamber 3. Since the middle of the two horizontally adjacent connecting rods 42 is rotatably connected by a connecting shaft, the upper ends of the connecting rods 42 move closer to the center of the drive chamber 3 under the rotational support of the connecting shaft. This causes the sliding seats 44 to slide on the outer surface of the corresponding sliding rods 43 towards the center of the drive chamber 3, while simultaneously pushing the lifting frame 45 upward. At the same time, the guide columns 5 slide inside the corresponding sliding openings, providing guidance and limiting for the vertical movement of the lifting frame 45, preventing the lifting frame 45 from shaking during the lifting process, and thus ensuring the stability of the position adjustment of the sealing machine 6. When the sealing machine 6 reaches the required height, the controller 22 shuts off the power. The self-locking performance of the worm gear and worm ensures the stable support of the lifting frame 45 by the connecting rod 42. Then, the controller 22 controls the operation of the two electric conveyor belts 19 on the front side. The external conveying equipment conveys the food to be protected to the front end of the electric conveyor belt 19. Under the conveying action of the electric conveyor belt 19, the food moves from front to back. At the same time, the controller 22 enables the motor 10 to operate. The output shaft of the motor 10 rotates, driving the unwinding roller 9 to rotate. The unwinding roller 9 unwinds the packaging film. Under the action of the external traction equipment, the packaging film, after being unwound by the unwinding roller 9, moves backward guided by the two guide plates 7. The middle part of the packaging film is in contact with the upper surface of the electric conveyor belt 19. The conveyed food is all located in the middle of the upper surface of the packaging film. Simultaneously, both sides of the packaging film are folded inward under the guidance of the corresponding guide plates 7. Then, when the packaging film passes through the sealing port of the sealing machine 6, the controller 22 starts the sealing machine 6, and the heater at the sealing port of the sealing machine 6 starts, while squeezing the edges of the packaging film, so that the heated and melted packaging film sticks together. At the same time, the packaging film and the food continue to move backward under the conveying action of the foremost electric conveyor belt 19. When the food reaches the front side of the support plate, the controller 22 shuts off the electric conveyor belt 19 and starts the electric push rod 13. The telescopic end of the electric push rod 13 extends and pushes the lifting plate 11 down. The downward movement of the lifting plate 11 drives the heating seat 15 and the cutting blade 16 down. At the same time, the controller 22 energizes the heating resistance wire at the lower end of the heating seat 15.The heating resistance wire generates heat when energized and transfers the heat to the lower surface of the heating base 15. When the lower surface of the heating base 15 contacts the packaging film, the upper and lower layers of the packaging film are thermally bonded. Simultaneously, the shearing blade 16, supported by the support plate, cuts the packaging film. After cutting, the controller 22 retracts the telescopic end of the electric push rod 13, thereby moving the lifting plate 11 upward. The upward movement of the lifting plate 11 moves the heating base 15 and the shearing blade 16 upward, ready for the next sealing cut. At this time, the controller 22 controls the front side... Two electric conveyor belts 19 operate, conveying the packaging film and food backward. When the food in the packaging film reaches the designated position on the rear electric conveyor belt 19, the controller 22 shuts off the electric conveyor belt 19 and activates the electric push rod 12 to perform heat sealing and cutting of the packaging film on the front part of the food again, thereby achieving closed packaging of the food. This cycle is repeated for packaging each food item. When the packaged food reaches the top of the rear electric conveyor belt 19 under the conveying action of the middle electric conveyor belt 19, the packaging... The weight of the packaged food is transferred to the weighing rack 18 via the rear electric conveyor belt 19. The weighing rack 18 then transfers the weight of the packaged food to the elastic diaphragm of the weighing sensor 21. The controller 22 activates the weighing sensor 21, causing the elastic diaphragm to deform proportionally to the pressure. This deformation changes the resistance values ​​of the four resistors in the piezoresistive bridge of the weighing sensor 21, causing the bridge to become unbalanced and output a voltage signal proportional to the pressure. The differential amplifier, built-in temperature sensor, and compensation algorithm inside the weighing sensor 21 amplify and process the voltage signal for interference suppression. The analog voltage signal is then converted into a digital signal by the A / D converter of the weighing sensor 21, and finally, the digital pressure signal is sent to the signal receiving end of the controller 22 in real time. The controller 22 records the weight of the weighed food. After weighing is complete, the controller 22 activates the rear electric conveyor belt 19 to transport the weighed food to the next working area and transports new food to be weighed to the middle of the weighing rack 18 for the next weighing.
