[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 7 , a vegetable packaging and weighing integrated machine, comprising a tower, a driving device and a plurality of hurdles;

[0024] The driving device is installed on the tower;

[0025] A plurality of the hurdles are arranged at intervals on the driving device;

[0026] The driving device drives the fence to cyclically move between the top and the bottom of the tower;

[0027] The fence is provided with a weighing module and a bag opening support rod;

[0028] The weighing module is arranged at the bottom of the fence and is used to weigh the quality of the vegetables;

[0029] A vegetable inlet is provided on one side of the fence, and the bag opening support rod can be rotatably arranged on the vegetable inlet of the fence.

[0030] From the above description, it can be seen that the present invention provides an integrated vegetable packaging and weighing machine, which includes a tower, a driving device and a plurality of fences. The plurality of fences are driven by the driving device to circulate between the top and the bottom of the tower, making full use of the three-dimensional space and saving floor space. Secondly, a weighing module is provided on each fence, which can automatically weigh the vegetables on the fence to realize the mass weighing function. In order to be able to put the vegetables into the packaging bag, each fence is provided with a bag opening support rod, which can support the bag opening to a certain opening, so as to facilitate the vegetables to be put into the packaging bag. It has a simple structure and low maintenance cost.

[0031] Furthermore, it also includes a suction cup module;

[0032] The suction cup module is installed at the bottom of the tower, and when one of the fences moves to the bottom of the tower, the suction cup module is located directly below the vegetable entrance of the fence;

[0033] A plurality of ventilation holes are arranged at the bottom of the fence near the vegetable entrance.

[0034] From the above description, it can be seen that the setting of the suction cup module can generate negative pressure around it. When the fence moves to the bottom of the tower, since the bottom of the fence is close to the vegetable entrance and has multiple air holes, under the adsorption force of the suction cup module, the lower edge of the packaging bag is tightly attached to the bottom of the fence under the action of the adsorption force, and the upper edge of the packaging bag is fixed at the top under the support of the bag opening support rod, thereby realizing the function of opening the bag opening, which is convenient for vegetables to enter the packaging bag.

[0035] Furthermore, the driving devices include two; the two driving devices are symmetrically arranged on opposite sides of the tower;

[0036] The driving device comprises a driving chain disc, a driven chain disc, a driving chain and a plurality of driving lugs;

[0037] The active chain disc and the driven chain disc are rotatably arranged on the side of the tower frame, respectively, and the rotation center of the active chain disc and the rotation center of the driven chain disc are located on the same vertical virtual line;

[0038] The drive chain is elliptical and laid in the tower, one arc section of which is arranged at the top of the tower and sleeved on the outer circumference of the driven chain plate; the other arc section is arranged at the bottom of the tower and sleeved on the outer circumference of the active chain plate;

[0039] A plurality of the driving lugs are installed at equal intervals on the end surface of the driving chain;

[0040] The plurality of fences are hinged to the plurality of different driving ears.

[0041] From the above description, it can be seen that the working principle is: the active chain plate rotates, driving the drive chain to move in a circular motion, and the drive ears arranged at intervals on the drive chain will move up and down in a circular motion with the drive chain, and the fence is hinged on the drive ears, thereby realizing the circular motion of the fence between the top and bottom of the tower.

[0042] Furthermore, it also includes a driving motor, a driving wheel, a driven wheel, a synchronous belt, a driving shaft and two sub-transmission shafts;

[0043] The driving motor is installed on the side of the tower, and its output shaft is coaxially and fixedly connected with the driving wheel; the driving wheel is connected to the driven wheel through the synchronous belt;

[0044] The driving shaft is rotatably arranged on two opposite sides of the tower; the driving shaft is coaxially and fixedly connected to the active chain plate; the driven wheel is coaxially and fixedly connected to the driving shaft;

[0045] The two sub-transmission shafts are rotatably arranged at the tops of two opposite side surfaces of the tower frame, and the two sub-transmission shafts are coaxially fixedly connected to two different driven chain discs respectively.

[0046] From the above description, it can be seen that the drive motor transmits power through the driving wheel, the driven wheel and the synchronous belt, with the purpose of reducing the rotation speed and increasing the driving torque.

[0047] Furthermore, when the hurdle is moved downward, a blocking cross bar is arranged on the side close to the driving shaft;

[0048] The distance between the blocking crossbar and the side of the hurdle is greater than the distance between the driving shaft and the same side of the hurdle;

[0049] The fence is provided with a vegetable unloading outlet on the side where the obstruction cross bar is located.

[0050] From the above description, the working principle can be known: during the downward movement of the fence, when the obstructing crossbar interferes with the drive shaft, the side of the fence where the obstructing crossbar is located moves upward around the hinge between the fence and the drive hook, and the opposite side moves downward around the hinge between the fence and the drive hook, thereby achieving a tipping effect, and then completing the unloading of the vegetables that have been packaged and weighed on the fence; after the fence passes the drive shaft, it returns to the horizontal plane by itself under the action of the fence's own gravity.

[0051] Further, it also includes a plurality of rollers;

[0052] A plurality of rollers are rotatably arranged on the blocking cross bar at intervals.

[0053] From the above description, it can be seen that the provision of the rollers can reduce the friction that hinders the crossbar and the drive shaft, reduce working noise, and also reduce wear on the drive shaft.

[0054] Further, the driving motor works intermittently;

[0055] When one of the fences moves to the bottom of the tower, the driving motor stops working.

[0056] From the above description, it can be seen that the purpose of the intermittent operation of the drive motor is that when a fence moves to the bottom of the tower, there is sufficient time to complete the loading of vegetables onto the fence, and it also gives the operator time to put the packaging bag on the bag mouth support rod.

[0057] Furthermore, it also includes a loading conveyor belt and a unloading conveyor belt;

[0058] The feeding conveyor belt is arranged at the bottom of the tower frame, and the end of the feeding conveyor belt is docked with the vegetable entrance of the fence frame moving to the bottom of the tower frame;

[0059] The end of the unloading conveyor belt is arranged on the side of the tower frame located downstream of the fence, and the working surface of the unloading conveyor belt is located below the driving shaft.

[0060] From the above description, it can be seen that the loading conveyor belt is used to load materials to the hurdles, wherein the loading conveyor belt needs to run alternately with the hurdles. When the hurdles stop moving, the loading conveyor belt starts running to complete the loading; when the hurdles are running, the loading conveyor belt stops running and waits for loading.

[0061] Further, it also includes controlling the motor;

[0062] The control motor is arranged on the side wall of the fence, and the output shaft of the control motor is fixedly connected to one end of the bag opening support rod.

[0063] From the above description, it can be seen that the control motor is used to control the rotation of the bag opening support rod. When the bag opening of the packaging bag needs to be supported, the control motor controls the bag opening support rod to flip upward, perpendicular to the side of the fence, to provide bag opening support; when the vegetable loading process is completed, the control motor controls the bag opening support rod to flip downward, parallel to the side of the fence, and removes the support to avoid interference between the packaging bag and the bag opening support rod during the unloading process.

The setting of the suction cup module 5 can generate negative pressure around it. When the fence 2 moves to the bottom of the tower 1, since the bottom of the fence 2 is provided with a plurality of air holes 6 near the vegetable entrance, under the adsorption force of the suction cup module 5, the lower edge of the packaging bag is pressed against the bottom of the fence 2 under the action of the adsorption force, and the upper edge of the packaging bag is fixed at the top under the support of the bag opening support rod 4, thereby realizing the function of opening the bag opening of the packaging bag, which is convenient for vegetables to enter the packaging bag.

[0092] In summary, the present invention provides a vegetable packaging and weighing integrated machine. When the fence moves to the bottom of the tower, the driving motor stops working, the fence stops moving, and the bag mouth of the packaging bag is manually put on the bag mouth support rod. At the same time, the suction cup module works. Since the bottom of the fence is close to the vegetable entrance and there are multiple air holes, under the adsorption force of the suction cup module, the lower edge of the packaging bag is tightly attached to the bottom of the fence under the adsorption force, thereby realizing the function of opening the bag mouth of the packaging bag, and the vegetables are transported to the packaging bag through the feeding conveyor belt; the motor starts working, and the fence continues to move with the drive chain; since each fence is provided with a weighing module, it can automatically weigh the vegetables on the fence, realize the mass weighing function, and transmit the weighing value to the linked control center. When the vegetable feeding process is completed, the control motor controls the bag mouth support rod to flip downward, parallel to the side of the fence, and remove the bag mouth support of the packaging bag. During the downward movement of the fence, when the obstructing crossbar interferes with the driving shaft, the side of the fence where the obstructing crossbar is located moves upward around the hinge between the fence and the driving hook, and the opposite side moves downward around the hinge between the fence and the driving hook, achieving a tipping effect, thereby completing the unloading of the vegetables that have been packaged and weighed on the fence; the unloaded vegetables fall onto the unloading conveyor belt and are transported out through the unloading conveyor belt; when the fence passes the driving shaft, it automatically returns to the horizontal plane under the action of its own gravity. Each fence repeats the above work to achieve continuous packaging and weighing.
