DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 5 The present invention provides a technical solution: a packaging device for powder coating production, comprising a base 1, on which a material holding device for storing powder coating is provided, such as Figure 1 As shown, the material holding device includes a material holding box 16 located above the base 1, the bottom edge of the base 1 is connected to the base 1 through a plurality of supporting legs 9, and a conical bucket 15 is provided at the bottom of the material holding box 16, so that the powder coating in the material holding box 16 can be concentrated into the conical bucket 15 under the action of gravity;

[0025] A discharging device for discharging a fixed amount of powder coating is provided at the bottom of the material containing mechanism. Specifically, the discharging device is arranged below the conical bucket 15. The discharging device includes a screw conveying shaft 11. The bottom of the conical bucket 15 is connected to the inlet of the screw conveying shaft 11. The powder coating in the conical bucket 15 will automatically flow into the screw conveying shaft 11. A discharging valve 12 is installed on the bottom outlet of the screw conveying shaft 11. The discharging valve is a special valve for powder.

[0026] When the screw conveyor shaft 11 is turned on, it continuously conveys the powder coating inside the material box 16 to the outside. In order to allow the output coating to fall directly into the packaging bag, a bag support mechanism is provided at the outlet of the discharge device. Figure 5 As shown, the bag-holding mechanism includes a six-axis mechanical arm 17 and a mounting frame 6 arranged on a base 1, the six-axis mechanical arm 17 and the mounting frame 6 are respectively arranged on both sides of the outlet, and a telescopic mechanism 7 facing the outlet is installed on the top of the mounting frame 6, and the telescopic mechanism 7 is one of a cylinder, a hydraulic cylinder or an electric cylinder, and a cylinder is preferably used in practical applications;

[0027] A suction cup bag-supporting robot is provided at the free end of the telescopic mechanism 7 and the six-axis robot arm 17, such as Figure 5 As shown, the suction cup bag holding manipulator includes a strip seat 18 respectively arranged on the six-axis robot arm 17 and the free end of the telescopic mechanism 7, and a plurality of suction cups 19 are arranged on the strip seat 18, and the strip seat 18 connected to the telescopic mechanism 7 is arranged horizontally, and the suction cup 19 is connected to the air supply system through a pipeline. It should be additionally explained here that when the telescopic mechanism 7 is a cylinder, it is also connected to the air supply system through a pipeline;

[0028] like Figure 3 As shown, a packaging bag placement area 13 is provided in the working area of ​​the six-axis robot 17 on one side thereof. The packaging bag placement area 13 is arranged on the base 1. Baffles 20 are vertically provided on both sides of the packaging bag placement area 13. The packaging bags are stacked between the two baffles 20. It should be noted that the distance between the two baffles 20 is only enough to lay one packaging bag flat. The packaging bags are stacked between the baffles 20 as shown in FIG. Figure 3 As shown, the baffle 20 can limit the position of a plurality of stacked packaging bags. When placing the packaging bags, the bag openings should face the discharge valve 12.

[0029] The specific bag-holding process is to let the six-axis robot 17 drive the bar seat 18 to be placed at the bag mouth of the packaging bag, and then the suction cup lifts a packaging bag and moves the packaging bag to the bottom of the discharge valve 12. At this time, the telescopic mechanism 7 extends, allowing the bar seat 18 at the end of the telescopic mechanism 7 and the bar seat 18 on the six-axis robot 17 to merge. At this time, the two bar seats 18 are respectively located on both sides of the bag mouth, and the suction cups 19 on the two bar seats 18 suck both sides of the bag mouth at the same time. Then the six-axis robot 17 and the telescopic mechanism 7 drive the bag mouth to retract at the same time, so that the bag mouth of the packaging bag is opened. At the same time, under the adsorption of the suction cup 19, the bag mouth is always held open. Subsequently, the powder coating discharged through the discharge valve 12 can flow into the interior of the packaging bag continuously. The entire packaging process allows the six-axis robot 17 and the telescopic mechanism 7 to operate reciprocatingly in this way;

[0030] like Figure 1 As shown, the discharge valve 12 is located above the bag-supporting mechanism, that is, the bottom outlet of the spiral conveying shaft 11 is located above the strip seat 18 to prevent the two strip seats 18 from touching the discharge valve 12 during movement.

[0031] Furthermore, a belt scale 4 is provided below the outlet of the discharge device. Figure 1 As shown, the belt scale 4 is specifically located below the discharge valve 12. During installation, the belt scale 4 is set on the base 1, and the belt scale 4 is located between the six-axis mechanical arm 17 and the mounting frame 6. When the packaging bag is opened, the bottom of the packaging bag sits on the belt scale 4, and the belt scale 4 can always sense the weight of the powder coating in the packaging bag;

[0032] When the belt scale senses that the weight of the packaging bag has reached a preset value, it will automatically move the packaging bag forward. In order to seal the bag opening, a packaging bag sealing machine 3 is provided on the side of the bag-supporting mechanism away from the material-containing device, and the bottom of the packaging bag sealing machine 3 is arranged on the base 1 through a bracket 2. Two limit plates 25 are provided between the packaging bag sealing machine 3 and the bag-supporting mechanism. The limit plates 25 are located above the belt scale 4, and the two limit plates 25 are distributed in a "V" shape. The narrow ends of the two limit plates 25 correspond to the inlet of the packaging bag sealing machine 3, and the sides of each limit plate 25 are respectively installed on the base 1 through a fixing frame 5. Specifically, when the weight of the packaging bag reaches the preset value, the packaging bag moves forward with the belt scale, and the positions of the two limit plates 25 should correspond to the positions of the packaging bag, so that during the movement of the packaging bag, the bag opening moves along the limit plates 25, and the bag opening can be sealed when it moves to the inside of the packaging bag sealing machine 3;

[0033] Then, if Figure 1As shown, at least one palletizing robot 22 is provided on the side of the packaging bag sealing machine 3 away from the bag-opening mechanism, and the palletizing robot 22 is arranged on the base 1. A handling manipulator 21 is installed on the free end of the palletizing robot 22, and a palletizing area 23 is provided on one side of the palletizing robot 22 within its working area. Figure 3 As shown, the palletizing robot 22 neatly palletizes the packaging bags on the palletizing area 23 .

[0034] Furthermore, in order to enable the above-mentioned components to operate automatically according to preset instructions, the present application also includes a control cabinet 8, which is provided with a controller, which is a PLC logic controller or a host computer. The controller is electrically connected to the air supply system, the stacking robot 22, the handling manipulator 21, the six-axis robot arm 17, the telescopic mechanism 7, the packaging bag sealing machine 3, the discharge valve 12 and the screw conveyor shaft 11, and an operation screen and control buttons electrically connected to the controller are also provided on the surface of the control cabinet 8.

[0035] Based on the above embodiment, further optimization can be performed. The strip seat 18 connected to the telescopic mechanism 7 may deflect. In order to avoid this situation, at least one guide shaft 26 parallel to the telescopic mechanism 7 is installed on the strip seat 18. The guide shaft 26 is movably arranged in the mounting frame 6, which can increase the stability of the reciprocating motion of the strip seat 18.

[0036] Based on the above embodiment, further optimization can be performed, where the bottom of the six-axis robot 17 is set on the second support platform 27, and the bottom of the palletizing robot 22 is set on the first support platform 24. In this way, the six-axis robot 17 and the palletizing robot 22 are set at high places, which can increase their own working areas.

[0037] Based on the above embodiment, further optimization can be performed. In order to increase the stability of the screw conveyor shaft 11, a reinforcement frame 14 is installed obliquely on the top of the screw conveyor shaft 11, and the top of the reinforcement frame 14 is connected to the reinforcement frame 10. The two ends of the reinforcement frame 10 are connected and fixed to the support legs 9. In this way, when the screw conveyor shaft 11 is extended to a large length, the reinforcement frame 14 can stably support the screw conveyor shaft 11.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
