[0039] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present application and with reference to the accompanying drawings.

[0040] As Figure 1-3 shown, an automatic plastic particle bagging, weighing and sealing machine includes: a frame 1, on which a bag roll 2, a bag opening component 3, a sealing component 6 and a traction roller 13 are sequentially arranged according to the bagging sequence, and a discharging component 4 is arranged above the bag opening component 3;

[0041] The bag roll 2 is formed by splicing a plurality of packaging bags. The upper side edge of the packaging bag is open. The bag roll 2 is rotatably arranged on one side of the frame 1, and the extending end of the bag roll 2 is pulled and moved by the traction roller 13;

[0042] The structure of the bag roll 2 is similar to that of a garbage bag roll. Adjacent packaging bags are spliced, and the opening of the packaging bag faces upward. The extending end of the bag roll 2 is driven by a pair of traction rollers 13. In a specific implementation manner, the traction roller 13 is driven by an external driving device, such as a driving motor. The two traction rollers 13 clamp the extending end of the bag roll 2. When the two traction rollers 13 cooperate and rotate, the bag roll 2 can be driven to extend.

[0043] The bag opening component 3 is used to open the packaging bag, the discharging component 4 is used to quantitatively put materials into the opened packaging bag, the sealing component 6 is used to seal the packaging bag loaded with materials, and the interval between the sealing component 6 and the bag opening component 3 is an integer multiple of the length of the packaging bag. By setting the interval between the sealing component 6 and the bag opening component 3 to be an integer multiple of the length of the packaging bag, since the operating positions of the two on the packaging bag are the same, it is convenient for the bag opening component 3 and the sealing component 6 to work simultaneously. The actions of the above-mentioned various components are uniformly controlled by an external controller and cooperate with each other.

[0044] As shown Figure 4-5 The discharging assembly 4 includes: a hopper 401, an upper part of the hopper 401 is provided with a feed inlet 402, an upper part of the feed inlet 402 is provided with a cover 403, a lower part of the hopper 401 is provided with a weighing tube 405, and a lower part of the weighing tube 405 is provided with a discharge pipe 407;

[0045] An upper part of an inner cavity of the weighing tube 405 is provided with a feed valve 408, a lower part of the inner cavity of the weighing tube 405 is rotatably connected with a turning plate 409, an upper surface of the turning plate 409 is provided with a pressure sensor 410, and an outside of the weighing tube 405 is provided with a turning plate motor 406 for driving the turning plate 409 to turn.

[0046] As shown Figure 4-5 A lower half of the hopper 401 is funnel-shaped, and an outer side wall of the lower half of the hopper 401 is provided with a vibration motor 404.

[0047] As shown Figure 6 The bag opening assembly 3 includes: a bag opening cylinder 301 arranged on a frame 1, an extending end of the bag opening cylinder 301 is provided with a vacuum suction plate 302, the bag opening cylinder 301 is arranged on one side of the packaging bag, the other side of the packaging bag is provided with a connecting plate 303, an end of the connecting plate 303 adjacent to the packaging bag is provided with a vacuum suction plate 302, and the connecting plate 303 is fixed on the frame 1.

[0048] As shown Figure 7 The sealing assembly 6 includes: a sealing cylinder 601, a hot pressing plate 602, a supporting block 603 and a plurality of auxiliary wheels 604;

[0049] The hot pressing plate 602 is fixedly connected to an extending end of the sealing cylinder 601, the hot pressing plate 602 and the supporting block 603 are distributed on two sides of the packaging bag, and the auxiliary wheels 604 are used for guiding the packaging bag.

[0050] Working principle: A traction roller 13 pulls an extending end of a bag roll 2, so that a bag opening of the packaging bag corresponds to a position of the bag opening assembly 3. The vacuum suction plate 302 of the bag opening assembly 3 is connected to an external vacuum pump to adsorb two sides of the bag opening of the packaging bag. The bag opening cylinder 301 acts to drive one side of the bag opening of the packaging bag to be pulled out to complete the bag opening action. After the bag opening is completed, a feed valve 408 in the discharging assembly 4 is opened, materials fall into the weighing tube and are measured by the pressure sensor 410. When the materials on the pressure sensor 410 reach a preset weight, the feed valve 408 is closed, and the turning plate motor 406 drives the turning plate 409 to turn, so that the materials enter the packaging bag through the discharge pipe 407. After the loading is completed, the traction roller 13 acts again to load the next packaging bag;

[0051] Since the interval between the sealing component 6 and the bag opening component 3 is an integral multiple of the length of the packaging bag, when one packaging bag is being loaded, another packaging bag is being sealed; during sealing, the sealing cylinder 601 in the sealing component 6 drives the hot pressing plate 602 to move towards the support block 603 to hot press the bag mouth of the packaging bag, completing the sealing operation; the above working processes are all controlled by an external control device, and the working speeds of each component are coordinated with each other.

[0052] As Figure 6 shown, a set of guide wheel components 5 are respectively arranged on both sides of the bag opening component 3;

[0053] The guide wheel component 5 includes: two support plates 501 fixedly connected to the frame 1, a moving plate 502 is slidably connected to each of the support plates 501, the moving plates 502 are distributed on both sides of the packaging bag, and a roller 503 is rotatably connected to the side adjacent to the packaging bag, and a locking screw 504 for locking the moving plate 502 is threadedly connected to the moving plate 502. By adjusting the guide wheel component 5, it is possible to prevent the bag roll 2 from running off during movement, affecting the bagging efficiency of the material.

[0054] As Figure 8 shown, a roll feeding component 9 for placing the bag roll 2 is arranged on one side of the frame 1, the roll feeding component 9 includes: a roll feeding motor 901 fixedly connected to the frame 1, a plug rod 903 is fixedly connected to the output end of the roll feeding motor 901, and a turntable 902 is arranged below the plug rod 903; the turntable 902 and the plug rod 903 are used for placing the bag roll 2. Through the setting of the roll feeding component 9, the rotation speed of the roll feeding motor 901 is adapted to the moving speed of the bag roll 2, which can keep the opened bag roll 2 under a certain tension and prevent it from being pulled off. The roll feeding component 9 can be used in cooperation with an external speed regulating device. The speed regulating device for adjusting the rotation speed of the roll feeding device is a conventional prior art and will not be elaborated here.

[0055] As Figure 1-2 shown, a conveying component is arranged on the frame 1, the conveying component includes: a driving wheel 8, a driven wheel 7, a conveyor belt 12 and a conveying motor 10; the driving wheel 8 and the driven wheel 7 are respectively rotatably connected to both ends of the frame 1, the conveyor belt 12 is sleeved on the driving wheel 8 and the driven wheel 7, a pulley component 11 is arranged on one side of the driving wheel 8, and the conveying motor 10 drives the driving wheel 8 to rotate through the pulley component 11. The specific structure of the pulley component 11 will not be elaborated here, and a conventional pulley drive structure can be adopted. Through the setting of the conveying component, it can play a role in supporting and assisting the movement of the packaged packaging bag, avoiding the total weight of the packaged packaging bag being too large, resulting in the traction roller breaking during pulling.

[0056] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
