[0029] It should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; Obviously, the examples in the specification are only a part of the embodiments of the present application, not all the embodiments.

[0031] The specific embodiments of the present application will be described in detail below. Figure 1 The specific embodiments of the present application will be described in detail below.

[0032] The present embodiment provides a kind of intelligent fast food packaging equipment, including rack 13, feeding mechanism, bag storage mechanism 11, bag taking mechanism 12, bag opening mechanism 16, bag clamping mechanism 15 and packaging mechanism.

[0033] Among them, rack 13 mainly provides hardware support for other mechanisms.

[0034] Further, the bottom end of the rack 13 is provided with a fixed plate 19, which is connected to the floor of the vehicle compartment. The various mechanisms of the device are rationally laid out and integrated, and the installation and integration of various parts are reinforced, so that the device is fully functional and minimized in size. It can be installed in the vehicle compartment as a vehicle-mounted reinforced device with fixed plate 19, which is convenient, fast, efficient and highly mobile, especially suitable for emergency support, rescue and disaster relief, field operations and the like.

[0035] Among them, the feeding mechanism includes a storage hopper 6, a metering screw 9 and a filling hopper 10, the storage hopper 6 is installed on the rack 13 and has a cylindrical discharge section at the bottom end, the metering screw 9 is installed in the storage hopper 6 and arranged in Z direction, the metering screw 9 is an equal-interval screw, the lower end of the metering screw 9 extends into the discharge section and is adapted in diameter to the discharge section, and the filling hopper 10 is installed on the rack 13 and can be driven to Z direction. The upper part of the filling hopper 10 is cylindrical and is gap-jointed on the outside of the discharge section, and the lower part of the filling hopper 10 is tapered and has a discharge port.

[0036] It is easy to understand that the metering screw 9 is an equal-interval screw, which can tightly fit the material with the discharge section by rotating, so that the volume of the material in the equal-interval screw space is the same, and the weight of the filled material is measured according to the volume of the material stored in the screw space. The total volume of the filled material can be controlled by setting the number of revolutions of the screw, so as to control the weight of the filled material each time.

[0037] It should be noted that the Z-direction lifting of the filling hopper 10 has two effects: firstly, the discharge opening of the filling hopper 10 is extended into the packaging bag for discharging or extracted from the packaging bag to avoid interference with other mechanism movements; secondly, the filling hopper 10 is quickly and reciprocally lifted by program control to achieve the effect of shaking, so as to shake the material adhered to the inner wall of the filling hopper 10 into the packaging bag.

[0038] Specifically, the filling hopper 10 is driven by a lifting air cylinder in the embodiment.

[0039] Further, the feeding mechanism of the embodiment further comprises a lifting motor 5 and a mounting plate, the fixed part of the lifting motor 5 is fixed on the rack 13, the mounting plate is fixed on the lifting part of the lifting motor 5, the metering screw 9 is rotatably installed on the mounting plate and connected with a screw driving element 4 installed on the mounting plate, and the storage hopper 6 is fixed below the mounting plate. In use, the mounting plate and the metering screw 9, the storage hopper 6 and the screw driving element 4 on the mounting plate are synchronously lifted by the lifting motor 5 until the discharge section at the bottom of the storage hopper 6 is separated from the filling hopper 10, at which time the storage hopper 6 is manually rotated to the outside of the rack 13, and the residual vegetable residues in the storage hopper 6 are washed by using a spray pipe, and the sewage flows downward along the storage hopper 6 to a sewage bucket, and the storage hopper 6 is reset after washing. In addition, each mechanism of the embodiment is designed as a quick assembly and disassembly structure, which can be quickly disassembled and separated for cleaning after the equipment completes the work, so as to ensure that each mechanism is thoroughly cleaned.

[0040] Specifically, the screw driving element 4 of the embodiment is a combination structure of a rotary motor and a synchronous belt.

[0041] Further, the feeding mechanism of the embodiment further comprises a stirring paddle 7, which is placed in the storage hopper 6 and fixedly sleeved on the upper end of the metering screw 9, and is used to stir the material and push the material in the upper part of the storage hopper 6 to the discharge section. The stirring paddle 7 adopts blades with a double-side inclination of 15 degrees to stir and push the material in the storage hopper 6 downward, so as to avoid the accumulation of the material in the storage hopper 6.

[0042] Specifically, the top side wall of the storage hopper 6 of the embodiment extends outward to form a filling port 8. The filling port 8 is used to supplement the material in the storage hopper 6, and the outward extension of the filling port 8 allows the material to be supplemented without stopping the machine, which is more efficient.

[0043] The bag storage mechanism 11 comprises a bag storage box fixed on the rack 13 and used to vertically stack the packaging bags, and the bottom of the bag storage box is provided with a bag outlet window.

[0044] Specifically, the bag storage box of the embodiment is fixedly composed of sheet metal parts. The bag storage box can cooperate with the limiting part to limit the packaging bag. The size of the bag storage box can be adjusted according to the size of the packaging bag, which can be easily designed by those skilled in the art.

[0045] It should be noted that the packaging bag is placed at the bottom of the bag storage box. Since the packaging bag is larger than the bag outlet window, it will not fall off. However, when the bag taking mechanism 12 sucks the packaging bag and pulls it down, the packaging bag will deform under stress and then be taken out through the bag outlet window.

[0046] As can be easily understood, when the packaging bag is placed in the bag storage box, the opening of the packaging bag faces the X direction side so as to face upward after the bag taking mechanism 12 is rotated by 90 degrees.

[0047] The bag taking mechanism 12 includes a bag taking suction cup. The suction surface of the bag taking suction cup is parallel to the Y direction axis. The bag taking suction cup is installed on the rack 13. The bag taking suction cup is driven to have the suction surface arranged along the XY plane and used to suck the packaging bag from the bag outlet window in a bag taking state and the suction surface arranged along the YZ plane in a bag feeding state. In action, the bag taking suction cup first takes the packaging bag from the bag storage box in the bag taking state, and then adjusts to the bag feeding state, moves to the lower side of the storage hopper 6, and waits for the bag opening operation.

[0048] As can be easily understood, a plurality of suction nozzles are arranged on the bag taking suction cup, and the plurality of suction nozzles are coplanar to form the suction surface.

[0049] Further, the bag taking mechanism 12 of the embodiment further includes a bag taking rotary pair and a bag taking linear pair. The fixed part of the bag taking rotary pair is fixed on the rack 13. The rotating part of the bag taking rotary pair is connected with the fixed part of the bag taking linear pair with the Y direction axis as the axis. The moving part of the bag taking linear pair is connected with the bag taking suction cup. In action, the bag taking rotary pair drives the bag taking linear pair and the bag taking suction cup to rotate synchronously to switch the bag taking suction cup to the bag taking state. The bag taking suction cup sucks the packaging bag and pulls it down to make the packaging bag deform and then be taken out through the bag taking window. Subsequently, the bag taking rotary pair drives the bag taking suction cup to switch to the bag feeding state. Then, the bag taking linear pair drives the bag taking suction cup to move towards the bag opening mechanism 16 in the X direction. The bag taking action is completed.

[0050] As can be easily understood, the bag taking linear pair outputs Z direction displacement in the bag taking state and outputs X direction displacement in the bag feeding state.

[0051] Specifically, the bag taking rotary pair of the embodiment is a rotary cylinder, and the bag taking linear pair is a telescopic cylinder.

[0052] The bag opening mechanism 16 comprises a bag opening suction cup, the suction surface of the bag opening suction cup is arranged along the YZ plane and opposite to the bag taking suction cup in the bag taking state, the bag opening suction cup is installed on the rack 13 and can be driven to translate along the X direction. In action, the bag taking suction cup and the bag opening suction cup move towards each other along the X direction, so that the packaging bag is located directly below the filling hopper 10, at this time the bag taking suction cup and the bag opening suction cup clamp the packaging bag, then the bag taking suction cup and the bag opening suction cup move away from each other along the X direction to open the packaging bag, and the bag opening action is completed.

[0053] Specifically, the embodiment adopts a telescopic cylinder to drive the bag opening suction cup to translate along the X direction.

[0054] The bag clamping mechanism 15 comprises a clamping jaw assembly, the clamping jaw assembly is installed on the rack 13 and can be driven to lift along the Z direction, the clamping jaw assembly comprises two clamping jaws arranged opposite to each other along the Y direction, and the two clamping jaws can be driven to move close to or away from each other. In action, when the bag taking suction cup and the bag opening suction cup clamp the packaging bag, the two clamping jaws move close to each other and clamp the two sides of the packaging bag along the Y direction, when the bag taking suction cup and the bag opening suction cup move away from each other to open the packaging bag, the two clamping jaws move close to each other synchronously to compensate for the reduction of the Y direction length of the packaging bag after the bag opening, so that the opening is kept in an open state, then the bag taking suction cup and the bag opening suction cup are separated from the packaging bag, and the clamping jaw assembly drives the packaging bag to move upwards so that the packaging bag reaches the sealing position, and the bag clamping action is completed.

[0055] Specifically, the embodiment adopts a lifting cylinder to drive the clamping jaw assembly to lift, adopts two telescopic cylinders arranged opposite to each other along the Y direction to drive the two clamping jaws to move close to or away from each other, and adopts a telescopic cylinder arranged along the X direction to cooperate with a single jaw hinged structure to realize the opening and closing of the clamping jaws.

[0056] The sealing mechanism comprises a vacuumizing assembly 20 and a heat sealing assembly 14, the vacuumizing assembly 20 comprises a vacuumizing pipe, the vacuumizing pipe is installed on the rack 13 and can be driven to extend into or out of the packaging bag, and the heat sealing assembly 14 is installed on the rack 13 and located above the bag clamping mechanism 15, the heat sealing assembly 14 comprises two heat sealing seats arranged opposite to each other along the X direction, and the two heat sealing seats can be driven to move close to or away from each other. The sealing mechanism performs two actions: vacuumizing and heat sealing. In vacuumizing, after the packaging bag reaches the sealing position and the filling is completed, the vacuumizing pipe extends into the packaging bag to perform vacuumizing, and the vacuumizing action is completed; in heat sealing, the two heat sealing seats of the heat sealing assembly 14 move close to each other to clamp the two sides of the opening of the packaging bag along the X direction, and the heat sealing action is completed after a set heat sealing time.

[0057] It should be noted that the heat sealing position of the packaging bag is located above the bag clamping position, so as to ensure that the bag clamping action and the heat sealing action do not interfere with each other.

[0058] In addition, the air compressor 18 is arranged on the frame 13 to provide high-pressure gas for the pneumatic structures of the bag taking mechanism 12, the bag opening mechanism 16, the bag clamping mechanism 15 and the packaging mechanism.

[0059] In addition, the packaging device of the embodiment is additionally provided with the bag supporting mechanism 17, which comprises a tray installed on the frame 13 and driven to be lifted in the Z direction to support the bottom end of the packaging bag during filling. Since the packaging bag is heavy after being filled with food, the bag clamping mechanism 15 may fail, so the bag supporting mechanism 17 is additionally provided. During operation, after the packaging bag is filled with food, the tray of the bag supporting mechanism 17 is lifted to contact and support the bottom end of the packaging bag, and the bag supporting operation is completed.

[0060] In addition, the packaging device of the embodiment is additionally provided with an electric control system, which comprises the electric control cabinet 1, the operation screen 2 and the indicator light 3. The electric control cabinet 1 is installed on the frame 13 and communicatively connected with the feeding mechanism, the bag taking mechanism 12, the bag opening mechanism 16, the bag clamping mechanism 15 and the packaging mechanism. The operation screen 2 and the indicator light 3 are both installed on the electric control cabinet 1.

[0061] Specifically, the electric control cabinet 1 of the embodiment is welded by sheet metal parts, and a maintenance door is arranged on the left side. The operation screen 2 is inlaid on the upper part. The operation screen 2 displays the running conditions of the device, such as the number, time and speed of packaging. Parameter settings can be made, such as the bag taking time and frequency, the bag opening time and frequency, the filling delay time, the bag feeding delay time, the vacuum extraction time and the sealing time. After the device is set with a packaging program, manual testing and continuous testing can be performed. The manual testing is gradually operated according to the set steps, and the parameter settings of each step can be improved. The indicator light 3 is arranged above the electric control cabinet 1 to display the working state. The indicator light 3 displays the corresponding color according to the working state of the device.

[0062] The working principle of the intelligent fast food packaging device of the embodiment is as follows:
