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 following will be described in detail Figure 1 The specific embodiments of the present application will be described in detail.

[0032] The present embodiment provides a rice ration packaging equipment, which comprises a rack 3, a feeding mechanism, a bag storage mechanism 1, a bag taking mechanism 2, a bag moving mechanism, a bag opening mechanism, a bag clamping mechanism 18 and a packaging mechanism.

[0033] Among them, the rack 3 is provided with a bag taking station, a charging station and a packaging station which are sequentially distributed along the X direction.

[0034] It is easy to understand that the rack 3 mainly provides hardware support for other mechanisms.

[0035] Further, the bottom end of the rack 3 is provided with a fixing plate 19 for connecting to the floor of the vehicle compartment. The various mechanisms of the device are integrated through rationalized layout, and the installation of various parts is integrated and reinforced, so that the device is fully functional and miniaturized. The device can be installed in the vehicle compartment as a vehicle-mounted reinforcement device, and has the characteristics of convenience, speed, efficiency and strong mobility, and is especially suitable for emergency support, rescue and disaster relief, and field operations.

[0036] The feeding mechanism includes a storage tank 15, a conveying screw 13, a strip baffle 21, a weigher 11, a bagging hopper 16, and a dosing hopper 12. The bottom of the storage tank 15 is provided with a cylindrical discharge part with an axis along the X direction. The conveying screw 13 is installed in the discharge part and matches the diameter of the discharge part. The right end of the bottom wall of the discharge part is provided with a discharge port. The strip baffle 21 is fixed below the storage tank 15 along the X direction. The left end of the strip baffle 21 is provided with a charging port at the charging station, and the right end is provided with a weighing hole corresponding to the discharge port. The weigher 11 is embedded in the weighing hole and the top weighing surface is flush with the strip baffle 21. The bagging hopper 16 is located below the charging port and is installed on the rack 3 and can be driven to move up and down in the Z direction. The dosing hopper 12 is installed on the rack 3 and located between the storage tank 15 and the strip baffle 21. The dosing hopper 12 is driven to move along the X direction to have a receiving state of abutting between the discharge port and the weigher 11 and a charging state of being located above the charging port. In operation, the storage tank 15 is filled with rice through the inlet at the top of the storage tank 15. The rice is conveyed by the conveying screw 13 to the right end of the discharge part, and then falls into the dosing hopper 12 in the receiving state through the discharge port. The weigher 11 measures the weight of the rice in the dosing hopper 12. When the preset value is reached, the conveying screw 13 stops rotating. The dosing hopper 12 moves to the left until it switches to the charging state. The rice falls into the filling hopper through the charging port. The filling hopper is quickly raised and lowered to generate vibration to make the rice inside fall into the packaging bag. The feeding work is completed.

[0037] Specifically, the conveying screw 13 is driven to rotate by a servo motor.

[0038] It is easy to understand that the weigher 11 is embedded in the weighing hole and the top weighing surface is flush with the strip baffle 21, which is to avoid the gap between the weigher 11 and the strip baffle 21, so that the rice falls outside the dosing hopper 12 and cannot move with the dosing hopper 12.

[0039] Specifically, the filling hopper is driven by a lifting cylinder. The Z-direction lifting of the filling hopper has two effects: one is that the filling hopper is inserted into the packaging bag to discharge or is pulled out of the packaging bag to avoid the action of other mechanisms; the other is that the filling hopper is lifted and lowered quickly and repeatedly to achieve the effect of shaking, so that the rice adhering to the inner wall of the filling hopper is shaken into the packaging bag.

[0040] Further, the feeding mechanism of the embodiment further comprises a scattering assembly 14, which comprises a scattering paddle arranged in the X-axis direction, the scattering paddle being installed on the upper part of the storage tank 15 and being driven to rotate along its own axis. After the rice enters the storage tank 15, the rice adhering together is first scattered by the rotation of the scattering paddle, so as to facilitate the rice to enter the conveying screw 13 below.

[0041] Specifically, the scattering paddle of the embodiment comprises a scattering shaft and a scattering blade fixed on the scattering shaft, and the scattering shaft is driven to rotate by a servo motor to drive the scattering blade to rotate.

[0042] The bag storing mechanism 1 is located at the bag taking station and comprises a bag storing box for vertically stacking the packaging bags, and the bottom of the bag storing box is provided with a bag taking window.

[0043] Specifically, the bag storing box of the embodiment is fixedly composed of sheet metal parts, and the packaging bags can be limited by cooperating with the limiting parts on the bag storing box. The size of the bag storing box can be adjusted according to the size of the packaging bags, which can be easily designed by those skilled in the art.

[0044] It should be noted that the packaging bag is placed at the bottom of the bag storing box, and since the packaging bag is larger than the bag taking window, it will not fall off. However, when the bag taking mechanism 2 sucks and pulls down the packaging bag, the packaging bag will be deformed under stress and then be taken out through the bag taking window.

[0045] It is easy to understand that when the packaging bag is placed in the bag storing box, the opening of the packaging bag faces the Y-direction side, so as to face upward after the bag taking mechanism 2 is rotated by 90 degrees.

[0046] The bag taking mechanism 2 is located below the bag storing mechanism 1 and comprises a bag taking suction cup, the suction surface of the bag taking suction cup is parallel to the X-axis, and the bag taking suction cup is driven to have the suction surface arranged in the XY plane and used in a bag taking state for sucking the packaging bag from the bag taking window and the suction surface arranged in the XZ plane and used in a bag conveying state. When in action, the bag taking suction cup first takes the packaging bag from the bag storing box in the bag taking state, and then is adjusted to the bag conveying state to wait for the bag moving operation.

[0047] It is easy to understand that a plurality of suction cups are arranged on the bag taking suction cup, and the plurality of suction cups are coplanar to form the suction surface.

[0048] Further, the bag taking mechanism 2 of the embodiment further comprises a bag taking rotary pair and a bag taking linear pair, the fixed part of the bag taking rotary pair is fixed on the frame 3, the rotating part of the bag taking rotary pair is connected with the fixed part of the bag taking linear pair with the X direction axis as the axis, and 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 adsorbs the packaging bag and pulls it down to make the packaging bag deform and then be taken out through the bag taking window, then the bag taking rotary pair drives the bag taking suction cup to switch to the bag sending state, and the bag taking action is completed.

[0049] It is easy to understand that the bag taking linear pair outputs Z direction displacement in the bag taking state and outputs Y direction displacement in the bag sending state.

[0050] Specifically, the bag taking rotary pair of the embodiment is a rotary cylinder, and the bag taking linear pair is a telescopic cylinder.

[0051] The bag moving mechanism comprises a moving plate, a first bag moving assembly 4 and a second bag moving assembly 6, the moving plate is installed on the frame 3 and can be driven to move along the X direction, the first bag moving assembly 4 comprises a bag moving suction cup, the bag moving suction cup is installed on the moving plate and can be driven to move along the Y direction, and the second bag moving assembly 6 comprises two bag moving clamping plates oppositely arranged in the Y direction, the two bag moving clamping plates are installed on the moving plate and can be driven to move close to or away from each other, and the interval between the bag moving suction cup and the bag moving clamping plates in the X direction is equal to the interval between the two adjacent workstations. In action, the bag moving suction cup and the bag moving clamping plates realize synchronous movement in the X direction through the moving plate: the bag moving suction cup is first moved to the bag taking workstation through the moving plate, then moves to the packaging bag and adsorbs it tightly through Y direction translation, the bag moving suction cup releases the vacuum, then moves to the loading workstation, and waits for loading; the bag moving clamping plates are first moved to the loading workstation through the moving plate and clamp the Y direction two sides of the packaging bag after loading, then are moved to the packaging workstation through the moving plate, and wait for packaging. That is, the first bag moving assembly 4 is used to realize the transfer of the packaging bag from the bag taking workstation to the loading workstation, the second bag moving assembly 6 is used to realize the transfer of the packaging bag from the loading workstation to the packaging workstation, and the two are synchronous.

[0052] Specifically, the embodiment adopts a telescopic cylinder arranged in the Y direction to drive the Y direction movement of the bag moving suction cup and the bag moving clamping plates.

[0053] The bag opening mechanism is located at the loading workstation, and the bag opening mechanism comprises a bag opening suction cup, the adsorption surface of the bag opening suction cup is arranged along the XZ plane, and the bag opening suction cup can be driven to move along the Y direction. In action, the bag moving suction cup and the bag opening suction cup move towards each other in the Y direction, so that the packaging bag is located directly below the loading hopper 16, at this time the bag moving suction cup and the bag opening suction cup clamp the packaging bag relative to each other, then the bag moving suction cup and the bag opening suction cup move away from each other in the X direction to open the opening of the packaging bag, and the bag opening action is completed.

[0054] Specifically, the telescopic air cylinder is used to drive the bag opening sucker to move in Y direction.

[0055] The bag clamping mechanism 18 is located at the loading station and above the bag opening mechanism. The bag clamping mechanism 18 includes two clamping jaws arranged opposite in X direction. The two clamping jaws are driven to approach or move away from each other. When the bag moving sucker and the bag opening sucker clamp the packaging bag, the two clamping jaws approach each other and clamp the two sides of the packaging bag in X direction. When the bag moving sucker and the bag opening sucker move reversely to open the bag, the two clamping jaws approach each other synchronously to compensate the reduction of the length of the packaging bag in X direction after the bag is opened, so that the opening is kept in open state. Then the bag moving sucker and the bag opening sucker are separated from the packaging bag, and the clamping action is completed.

[0056] Specifically, the telescopic air cylinder arranged opposite in X direction is used to drive the two clamping jaws to approach or move away from each other. The telescopic air cylinder arranged in Y direction is used to cooperate with the single jaw hinged structure to realize the opening and closing of the clamping jaws.

[0057] The packaging mechanism includes the vacuum pumping assembly 17 and the heat sealing assembly 20. The vacuum pumping assembly 17 is located at the loading station and includes a vacuum pumping pipe which is installed on the rack 3 and is driven to extend into or out of the packaging bag. The heat sealing assembly 20 is located at the packaging station and includes two heat sealing seats arranged opposite in Y direction. The two heat sealing seats are driven to approach or move away from each other. The packaging mechanism performs two actions: vacuum pumping and heat sealing. When vacuum pumping, after the packaging bag is filled, the vacuum pumping pipe extends into the packaging bag to perform vacuum pumping. When heat sealing, the two heat sealing seats of the heat sealing assembly 20 approach each other to clamp the two sides of the opening of the packaging bag in Y direction. After the set heat sealing time, the heat sealing action is completed.

[0058] In addition, the air compressor 8 is arranged on the rack 3 to provide high pressure gas for the pneumatic structures of the bag taking mechanism 2, the bag moving mechanism, the bag opening mechanism, the bag clamping mechanism 18 and the packaging mechanism.

[0059] In addition, the packaging equipment of the embodiment is additionally provided with the bag supporting mechanism 5. The bag supporting mechanism 5 includes a supporting tray which is installed on the rack 3 and is driven to lift and lower in Z direction to support the bottom end of the packaging bag during loading. Since the packaging bag is heavy after being filled with rice, the bag supporting mechanism 5 is additionally provided to prevent the bag clamping mechanism 18 from failing. After the packaging bag is filled with food, the supporting tray of the bag supporting mechanism 5 is lifted to contact and support the bottom end of the packaging bag, and the bag supporting action is completed.

[0060] In addition, the packaging equipment of the embodiment further includes the guide plate 7 which is located at the packaging station and below the packaging mechanism. The upper plate surface of the guide plate 7 is provided with an inclined surface to guide the falling packaging bag to slide to the outside of the equipment. After packaging is completed, the two heat sealing seats are reset, the packaging bag falls on the guide plate 7 and slides to the outside of the equipment along the inclined surface of the guide plate 7 for collection.

[0061] In addition, the packaging device of the embodiment further comprises an electric control system, which comprises an electric control cabinet 9 and an operation screen 10, both of which are installed on the rack 3. The electric control cabinet 9 is in communication connection with the feeding mechanism, the bag taking mechanism 2, the bag moving mechanism, the bag opening mechanism, the bag clamping mechanism 18 and the packaging mechanism. The operation screen 10 is in communication connection with the electric control cabinet 9.

[0062] Specifically, the electric control cabinet 9 of the embodiment is welded by sheet metal parts, and a maintenance door is arranged on the right side. An operation screen 10 is inlaid on the upper part. The operation screen 10 displays the running condition of the device, the packaging quantity, time, speed and the like. Parameter setting can be performed, such as the bag taking time and frequency, the bag opening time and frequency, the filling delay time, the bag feeding delay time, the vacuumizing time and the sealing time. After the device is set with the packaging program, manual test and continuous test can be performed.
