Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1-4 shown, a dye dispensing system includes a conveyor belt 1, a rotary dispensing device 2 and a material tank 3. The conveyor belt 1 is used to convey cartons with packaged bags. The bags are large bags that are directly sleeved inside the cartons and have open tops to receive dye products. Along the traveling direction of the conveyor belt 1, a box placing station 11, a dispensing station 12 and a box sealing station 13 are sequentially arranged. Workers are arranged at the box placing station 11 to place empty cartons. The dispensing station 12 completes the dispensing and filling operation of the dye products. Workers are arranged at the box sealing station 13 to tie the bag mouths to complete the closing of the cartons. Under the above layout, the packaging of dye products can achieve a flow operation, and compared with the previous messy operation, the packaging production efficiency is greatly improved. In the present invention, an automated rotary dispensing device 2 is adopted at the dispensing station 12 to quantitatively fill the dye products. The rotary dispensing device 2 is installed on the side of the conveyor belt 1 and is installed corresponding to the dispensing station 12. When the carton rotates to the dispensing station 12, it will stay for a period of time, and then the dye products are filled through the rotary dispensing device 2. The rotary dispensing device 2 includes a vertically and rotatably installed rotating shaft 21. A dispensing pipe 22 is connected to the outside of the rotating shaft 21. The dispensing pipe 22 is hollow and can be filled with materials (the materials are the dye products) inside. The rotating shaft 21 drives the dispensing pipe 22 to rotate. A replenishment station 221 is arranged along the rotation direction of the dispensing pipe 22. The material tank 3 is installed corresponding to the replenishment station 221. The dispensing pipe 22 will communicate with the outlet of the material tank 3 at the replenishment station 221, and the material tank 3 will form a material replenishment and filling effect on the dispensing pipe 22. The dispensing pipe 22 will rotate through the dispensing station 12, and the dispensing pipe 22 will form a discharging effect at the dispensing station 12, and will discharge the materials inside the pipe to the carton at the dispensing station 12. Since the internal capacity of the dispensing pipe 22 is fixed, the amount of dye products filled into the corresponding carton each time is fixed, and the purpose of quantitative filling can be achieved. As the conveyor belt 1 conveys, cartons can be continuously provided, and as the dispensing pipe 22 rotates, dye products can be continuously filled into each carton. The rotary dispensing device 2 has the function of automatically quantitatively filling dye products. After applying the rotary dispensing device 2, the dispensing station 12 can achieve automated operation, greatly improving the filling efficiency and filling quality, and at the same time reducing the use of labor.

[0022] As Figure 2As shown, the rotary filling device 2 also includes a rotary power component 23, which is transmission-connected to the rotating shaft 21. The rotary power component 23 includes a motor frame 231 and a first motor 232. The first motor 232 is installed on the motor frame 231. The output shaft of the first motor 232 is connected to the rotating shaft 21. The first motor 232 can drive the rotating shaft 21 to rotate to form a rotation effect of the filling tube 22.

[0023] like Figure 3 As shown, a connecting rod 211 is fixedly connected to the outer wall of the rotating shaft 21, and the connecting rod 211 is vertically connected to the outer wall of the rotating shaft 21. A filling tube 22 is fixedly connected to the outer end of the connecting rod 211. The filling tube 22 is vertically installed. There are four filling tubes 22, and the four filling tubes 22 are evenly distributed on a circular line with the rotating shaft 21 as the center axis. The rotating shaft 21 rotates exactly ninety degrees each time it is started. Each time it is started, there will be a filling tube 22 in the replenishment station 221, and there will be a filling tube 22 in the filling station 12. That is to say, the first motor 232 starts intermittently, and each time it is started, it drives the rotating shaft 21 to rotate ninety degrees. In this way, there is exactly one filling tube 22 filling the dye product, and another filling tube 22 distributing and filling the dye product.

[0024] like Figure 2As shown, the rotary dispensing device 2 further includes a first pipe-sealing disc 24, a second pipe-sealing disc 25, and a disc rack 26. The first pipe-sealing disc 24 and the second pipe-sealing disc 25 are connected to the disc rack 26. For the convenience of replenishing and discharging the dye product, the dispensing pipe 22 is designed with an upper and lower through structure. The upper end is open to replenish the dye product, and the lower end is open to discharge the dye product. In order to enable the two open ends of the dispensing pipe 22 to be opened at specific positions, the present utility model designs the structures of the first pipe-sealing disc 24 and the second pipe-sealing disc 25 to cooperate. The lower end surface of the first pipe-sealing disc 24 is in close contact with the top of the dispensing pipe 22, and the lower end surface of the first pipe-sealing disc 24 forms a sealing effect on the top of the dispensing pipe 22. The upper end surface of the second pipe-sealing disc 25 is in close contact with the bottom of the dispensing pipe 22, and the upper end surface of the second pipe-sealing disc 25 forms a sealing effect on the bottom of the dispensing pipe 22. The first pipe-sealing disc 24 and the second pipe-sealing disc 25 do not affect the rotation of the dispensing pipe 22, but can form a sealing effect at both ends on the rotating dispensing pipe 22 to prevent the abnormal falling out of the dye product in the pipe. The first pipe-sealing disc 24 is provided with a first through hole 241, and the first through hole 241 is opened corresponding to the replenishment station 221. The material tank 3 is provided with a discharge pipe 31, and the discharge pipe 31 is connected to the first through hole 241. When the dispensing pipe 22 rotates to the replenishment station 221, the discharge pipe 31 of the material tank 3, the first through hole 241, and the top open end of the dispensing pipe 22 are in a straight line up and down. Through the first through hole 241, the material tank 3 and the dispensing pipe 22 are connected, and the dye product in the material tank 3 can be naturally output into the dispensing pipe 22 and fill the inside of the dispensing pipe 22. Since the internal space of the dispensing pipe 22 is fixed, quantitative filling can be achieved. The second pipe-sealing disc 25 is provided with a third through hole 251, and the third through hole 251 is opened corresponding to the dispensing station 12. When the dispensing pipe 22 rotates to the dispensing station 12, the bottom open end of the dispensing pipe 22 is communicated with the third through hole 251, and the blocking effect at the bottom of the dispensing pipe 22 disappears, and the material in the dispensing pipe 22 leaks out and is quantitatively filled into the carton packaging bag below.

[0025] As Figure 1 and Figure 2A dye dispensing system as shown also includes a dispensing auxiliary mechanism 4. The dispensing auxiliary mechanism 4 is installed corresponding to the dispensing station 12. The dispensing auxiliary mechanism 4 plays an auxiliary role in discharging the dispensing pipe 22. The dye product in the dispensing pipe 22 is in powder form. There will be a situation where a small amount of product remains adhered to the inner wall of the pipe when discharging solely by gravity. The present utility model solves the above problems by designing the dispensing auxiliary mechanism 4. The dispensing auxiliary mechanism 4 includes a push cylinder frame 41 and a piston push cylinder 42. The piston push cylinder 42 is vertically installed downward on the push cylinder frame 41. The piston rod end of the piston push cylinder 42 is connected with a pipe cleaning piston 43. A second through hole 242 is formed in the first pipe sealing disc 24. The second through hole 242 and the third through hole 251 are arranged vertically and correspond to each other. When the dispensing pipe 22 is at the dispensing station 12, the bottom opening of the dispensing pipe 22 is communicated with the third through hole 251, and the top of the dispensing pipe 22 is communicated with the second through hole 242. The dispensing pipe 22 forms a state of being directly through from top to bottom. The size of the pipe cleaning piston 43 matches the inner size of the dispensing pipe 22. The pipe cleaning piston 43 can be driven downward by the piston push cylinder 42. The pipe cleaning piston 43 can be inserted into the dispensing pipe 22 after passing through the second through hole 242, forming a scraping effect on the inner wall of the dispensing pipe 22, removing the product residue on the inner wall of the pipe, ensuring that the dye product can be output in sufficient quantity, and this effect can also improve the accuracy of the filling volume.

[0026] As Figure 2 shown, the first pipe sealing disc 24 is bolted to the disc frame 26, and the second pipe sealing disc 25 is welded to the disc frame 26. The position of the second pipe sealing disc 25 is fixed, and the position of the first pipe sealing disc 24 can be adjusted up and down. Due to different requirements for the filling volume, dispensing pipes 22 of different heights can be selected (when the diameter remains unchanged, changing the height can change the product capacity of the dispensing pipe 22). When dispensing pipes 22 of different heights are selected, the position of the first pipe sealing disc 24 needs to be adjusted up and down to ensure that it forms a sealing effect on the top of the dispensing pipe 22. In the case of bolt connection, it is convenient for adjustment operation.

[0027] As Figure 2As shown in the figure, the discharge pipe 31 of the material tank 3 needs to be kept connected to the first through hole 241 of the first pipe sealing plate 24. When the position of the first pipe sealing plate 24 is adjusted, the installation height of the material tank 3 also needs to be adjusted. Therefore, the present utility model further includes a material tank lifting mechanism 5. The material tank 3 is installed on the material tank lifting mechanism 5. The material tank lifting mechanism 5 includes a lifting frame 51, a transmission screw 52, a guide rod 53, a tank receiving cross beam 54 and a second motor 55. The transmission screw 52 is rotatably installed on the lifting frame 51. The guide rods 53 are arranged on both sides of the transmission screw 52 and are fixedly installed. The tank receiving cross beam 54 is inserted through the two guide rods 53 and is threadedly connected to the transmission screw 52. The output end of the second motor 55 is connected to the transmission screw 52. The guide rod 53 plays a role in guiding and restricting the movement of the tank receiving cross beam 54. When the second motor 55 drives the transmission screw 52 to rotate, the tank receiving cross beam 54 can move along the length direction of the guide rod 53 (that is, vertical lifting movement). The material tank 3 is fixedly connected to the tank receiving cross beam 54. The material tank lifting mechanism 5 can drive the material tank 3 to do vertical lifting movement. The top of the material tank 3 is provided with a feed pipe 32, which can continuously supply and input dye products into the material tank 3 to ensure the sufficiency of the products in the material tank 3.

[0028] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
