[0108] According to the attached Figure 1 To Attachment Fig.13 As shown, a pet food automatic packaging machine according to a preferred embodiment of the present invention will be described in detail below, wherein the pet food automatic packaging machine includes a rotating working table 10, a bag-supporting device 20 and a detection device 30.

[0109] Specifically, the rotating working table 10 includes at least two clamping parts 11. The two clamping parts 11 are spaced apart and arranged on the outer edge surface of the rotating working table 10. The clamping parts 11 are used to clamp the pet food packaging bag.

[0110] More specifically, the bag-supporting device 20 and the detecting device 30 each correspond to one of the clamping parts 11 after the rotating working table 10 rotates a certain angle.

[0111] Specifically, the bag-holding device 20 includes a first lifting component 21 and a bag-holding component 22. The bag-holding component 22 is installed on the first lifting component 21 and moves up and down as the first lifting component 21 rises and falls. The bag-holding component 22 is used to hold open the pet food packaging bag.

[0112] Specifically, the detection device 30 includes a second lifting component 31 and a detection component 32. The detection component 32 is installed on the second lifting component 31 and moves up and down with the lifting and lowering of the second lifting component 31. When the detection component 32 moves downward, the pet food packaging bag opened by the bag-opening device 20 is inserted.

[0113] Specifically, the clamping portion 11 includes two clamp arm cylinders 111 and two clamp claws 112 . The two clamp arm cylinders 111 are arranged in parallel to the rotating working table 10 . The two clamp claws 112 are swingably mounted on one end of the clamp arm cylinder 111 extending out of the rotating working table 10 .

[0114] It can be understood by those skilled in the art that the driving member for driving the clamping jaws 112 to swing can be set as a pneumatic cylinder or an oil cylinder, etc. When the pet food packaging bag is placed between the clamping arm cylinder 111 and the clamping jaws 112, the two clamping jaws 112 swing to clamp the pet food packaging bag together with the clamping arm cylinder 111. Thereafter, the pet food packaging bag enters the next process and is opened as the rotating working table 10 rotates.

[0115] Specifically, the first lifting assembly 21 includes a first lifting platform 211 and a first telescopic cylinder 212 . The first telescopic cylinder 212 is installed on the first lifting platform 211 , and the bag-supporting assembly 22 is disposed on the first telescopic cylinder 212 .

[0116] Specifically, the bag-supporting assembly 22 includes a second mounting frame 221, two suction units 222 and a blowing nozzle 223. The second mounting frame 221 is fixedly mounted on the output end of the first telescopic cylinder 212. The two suction units 222 can be slidably mounted on the second mounting frame 221 relative to or opposite to each other. The blowing nozzle 223 is mounted on the second mounting frame 221 and is located between the two suction units 222.

[0117] Furthermore, the adsorption unit 222 includes a negative pressure tube 2221 and at least one first suction cup 2222 , the negative pressure tube 2221 has at least one negative pressure port 222101 , and the first suction cup 2222 is installed at the negative pressure port 222101 .

[0118] Preferably, two sliding grooves 22101 are formed on the second mounting frame 221, and the negative pressure tube 2221 is slidably mounted in the sliding grooves 22101. That is, when the two adsorption units 222 slide relative to or away from each other, the two negative pressure tubes 2221 slide relative to or away from each other in the sliding grooves 22101 on their corresponding sides.

[0119] Preferably, the first suction cup 2222 is configured to be made of silica gel. Those skilled in the art will appreciate that the first suction cup 2222 made of silica gel is suitable for adsorbing objects with smooth surfaces and is not easy to fall off, thereby improving the adsorption effect of the first suction cup 2222 on the pet food packaging bag.

[0120] Furthermore, the adsorption unit 222 also includes two auxiliary telescopic cylinders 2223, which are installed on the second mounting frame 221 and connected to the negative pressure tube 2221, and the auxiliary telescopic cylinders 2223 are used to drive the two adsorption units 222 to slide relative to or away from each other.

[0121] Preferably, the number of the negative pressure ports 222101 can be set according to the length of the pet food packaging bag, and the arrangement direction of the multiple negative pressure ports 222101 is the same as the length direction of the pet food packaging bag. In this embodiment, the number of the negative pressure ports 222101 is set to two, and accordingly, the number of the first suction cups 2222 is also two. It can be understood by those skilled in the art that the two first suction cups 2222 can effectively absorb the pet food packaging bag as a whole, thereby improving the effect of opening the pet food packaging bag.

[0122] Specifically, the bag-supporting device 20 further includes a first negative pressure pump 23 and an air pump 24 . The first negative pressure pump 23 is connected to the two negative pressure pipes 2221 via pipelines, respectively, and the air pump 24 is connected to the blowing nozzle 223 via pipelines.

[0123] It can be understood by those skilled in the art that when the rotating working table 10 clamps the pet food packaging bag and rotates to the bag-holding device 20, the bag-holding assembly 22 moves downward under the drive of the first telescopic cylinder 212 until the adsorption units 222 are located on both sides of the pet food packaging bag. At this time, the two adsorption units 222 move relatively to the first suction cup 2222 and contact the bag wall of the pet food packaging bag under the drive of the auxiliary telescopic cylinder 2223. At this time, the first suction cups 2222 on both sides adsorb the bag body of the pet food packaging bag on the first suction cup 2222 under the drive of the first negative pressure pump 23, and then the two adsorption units 222 move away from each other under the drive of the auxiliary telescopic cylinder 2223. The pet food packaging bag is gradually pulled open as the adsorption units 222 on both sides move away from each other. At this time, the adsorption units 222 remain stationary, and the air pump 24 runs and blows the generated air into the pulled open pet food packaging bag through the blowing nozzle 223, thereby further improving the effect of the pet food packaging bag being stretched open. Then, the first negative pressure pump 23 and the air pump 24 stop running, the first suction cup 2222 is no longer in contact with the pet food packaging bag, and the bag support assembly 22 is driven by the first lifting assembly 21 to move upward and away from the pet food packaging bag.

[0124] Specifically, the second lifting assembly 31 includes a second lifting platform 311 and a second telescopic cylinder 312 . The second telescopic cylinder 312 is installed on the second lifting platform 311 , and the detection assembly 32 is disposed on the second telescopic cylinder 312 .

[0125] Specifically, the detection assembly 32 includes a detection head 321 and a plurality of sensors 322, the detection head 321 is connected to the second telescopic cylinder 312, and the plurality of sensors 322 are installed at intervals at the lower end of the detection head 321. It can be understood by those skilled in the art that, when the clamping portion 11 clamps the stretched packaging bag and is located below the detection head 321 under the rotation of the rotating working table 10, the detection head 321 moves downward under the drive of the second telescopic cylinder 312 and extends into the stretched pet food packaging bag. At this time, the sensors 322 located at the lower end of the detection head 321 can sense the bag body of the pet food packaging bag, indicating that the packaging bag is effectively stretched. After the detection is successful, the detection assembly 32 moves upward to be away from the pet food packaging bag under the drive of the second telescopic cylinder 312, and then the rotating working table 10 rotates to the next step by clamping the pet food packaging bag through the clamping portion 11. If one of the sensors 322 fails to sense the bag body of the pet food packaging bag, it means that the pet food packaging bag has not been successfully opened, and the food packaging bag will not be further operated in the subsequent process, thereby reducing waste and improving packaging efficiency.

[0126] Preferably, the pet food automatic packaging machine also includes a bag supply device 40, which includes a placement component 41, a bag retrieval component 42 and a bag supply component 43.

[0130] Specifically, the bag taking assembly 42 includes a third telescopic cylinder 421, an adsorption component 422 and a second negative pressure pump 423. The adsorption component 422 is installed on the third telescopic cylinder 421, and the second negative pressure pump 423 is connected to the adsorption component 422 via a pipeline.

[0132] Preferably, a mounting groove 422101 matched with the second suction cup 4222 is formed on the adsorption plate 4221 , and the second suction cup 4222 is installed in the mounting groove 422101 .

[0133] Preferably, the shape of the adsorption plate 4221 is the same as the shape of the removal port 41201 , and the area of ​​the adsorption plate 4221 is slightly smaller than the area of ​​the removal port 41201 .

[0134] Preferably, the number of the second suction cups 4222 can be set according to the length of the pet food packaging bag, and the arrangement direction of the plurality of second suction cups 4222 is the same as the length direction of the pet food packaging bag. In this embodiment, the number of the second suction cups 4222 is set to two, and accordingly, the number of the mounting slots 422101 is also two. It can be understood by those skilled in the art that the two second suction cups 4222 can increase the adsorption effect on the packaging bag, thereby increasing the success rate of removing the packaging bag from the support plate 412.

[0139] Those skilled in the art will appreciate that when a packaging bag needs to be clamped, the clamping plate 4322 can be moved close to another clamping plate 4322 to clamp the packaging bag, and when the packaging bag no longer needs to be clamped, the clamping plate 4322 can be moved away from another clamping plate 4322.

[0140] Preferably, the automatic pet food packaging machine further comprises a material dispensing device 50 , and the material dispensing device 50 comprises a loading rack 51 and a material dispensing assembly 52 .

It can be understood by those skilled in the art that when the food sliding down from the second funnel 5211 contacts the protrusion 52121, it will slide down along the protrusion 52121 into the diverter plate 5213, and be diverted to the quantitative component 522 through the diverter plate 5213.

[0145] Specifically, the diverter plate 5213 has a high end 52131 and a low end 52132, the high end 52131 of the diverter plate 5213 is arranged below the cap-shaped plate 5212, and the low end 52132 of the diverter plate 5213 is arranged above the first funnel 523. It can be understood by those skilled in the art that the food falling into the second funnel 5211 continues to slide downward to the cap-shaped plate 5212 due to gravity, and contacts the protrusion 52121 in the middle of the cap-shaped plate 5212, so as to be dispersed and slide to the edge of the cap-shaped plate 5212 and fall into the high end 52131 of the diverter plate 5213, at this time, due to the height difference between the high end 52131 and the low end 52132, the food slides along the diverter plate 5213 to the quantitative component 522.

[0146] Specifically, the quantitative component 522 includes two quantitative parts 5221 placed one above the other, the quantitative part 5221 includes a certain amount channel 52211, a balanced weigher 52212 and a baffle 52213, the quantitative channel 52211 has an upper opening 5221101 and a lower opening 5221102, the balanced weigher 52212 and the baffle 52213 are hinged to the lower opening 5221102 of the quantitative channel 52211, and the lower opening 5221102 of the quantitative channel 52211 can be blocked by swinging.

[0147] It can be understood by those skilled in the art that when the food slides down to the quantitative channel 52211 above through the diverter plate 5213, the lower opening 5221102 of the quantitative channel 52211 is blocked by the relatively swinging balanced weigher 52212 and the baffle 52213. At this time, the balanced weigher 52212 weighs the food falling into the quantitative channel 52211. After the weighing is completed, the balanced weigher 52212 and the baffle 52213 swing in opposite directions and no longer block the food. The lower opening 5221102 of the quantitative channel 52211, the food in the quantitative channel 52211 falls into the quantitative channel 52211 below and is weighed again. When the system detects that the sum of the weights of several of the quantitative pieces 5221 below is the set quantitative, the lower openings 5221102 of the above quantitative pieces 5221 are opened and the food in the quantitative channel 52211 falls into the first funnel 523, and continues to slide to the packaging bag that is stretched below to complete the final filling. Secondly, the two quantitative pieces 5221 placed up and down not only accurately weigh the results, but also the alternating dropping of the two quantitative pieces 5221 improves production efficiency and avoids the occurrence of food stacking in the quantitative piece 5221 above.

[0148] Specifically, the first funnel 523 has a feed port 52301 and a discharge port 52302 , the lower end of the quantitative member 5221 below is inserted into the feed port 52301 , and the discharge port 52302 is located directly above the opening of the packaging bag that is stretched open.

[0149] Preferably, the material distributing device 50 further includes a mounting platform 53 , and the material distributing component 52 is disposed on the mounting platform 53 .

[0150] Preferably, the pet food automatic packaging machine further comprises a heat sealing device 60 , wherein the heat sealing device 60 comprises a fourth lifting component 61 and a heat sealing component 62 , wherein the heat sealing component 62 is disposed on the fourth lifting component 61 and moves up and down as the fourth lifting component 61 is lifted or lowered.

[0151] Specifically, the fourth lifting assembly 61 includes a fourth lifting platform 611 and a fourth telescopic cylinder 612 . The fourth telescopic cylinder 612 is installed on the fourth lifting platform 611 , and the heat sealing assembly 62 is disposed on the fourth telescopic cylinder 612 .

[0152] Specifically, the heat sealing assembly 62 includes a third mounting frame 621 and two heating plates 622 , and the two heating plates 622 are mounted on the third mounting frame 621 so as to be slidable relative to or opposite to each other.

[0153] Preferably, the heat sealing assembly 62 further comprises two heat sealing telescopic cylinders 623, which are mounted on the third mounting frame 621 and connected to the heating plate 622, and are used to drive the two heating plates 622 to slide relative to or opposite to each other. It can be understood by those skilled in the art that after the packaging bag filled with pet food moves below the two heating plates 622 under the drive of the rotating work table 10, the heat sealing assembly 62 moves downward under the drive of the fourth telescopic cylinder 612 until the two heating plates 622 are located at the opening of the packaging bag and the packaging bag is located between the two heating plates 622. At this time, the two heating plates 622 move relative to each other and clamp the bag opening of the packaging bag under the drive of the heat sealing telescopic cylinder 623, thereby achieving heat sealing of the bag opening of the packaging bag. After the heat sealing is completed, the two heating plates 622 move opposite to each other and move upward to the original position.

[0154] Preferably, the pet food automatic packaging machine further comprises a conveyor 70, and the conveyor 70 has an inlet end 71 and an outlet end 72. It is understood by those skilled in the art that when the rotating work table 10 rotates the heat-sealed packaging bag to above the inlet end 71 of the conveyor 70 via the clamping portion 11, the two clamping jaws 112 no longer clamp the two sides of the packaging bag, and the heat-sealed packaging bag falls to the inlet end 71 of the conveyor 70 and is transmitted to the outlet end 72.

[0155] Preferably, the pet food automatic packaging machine also includes a controller 80, and the rotating working table 10, the bag holding device 20, the detection device 30, the bag supply device 40, the heat sealing device 60 and the material dividing device 50 are all electrically connected to the controller 80, and the controller 80 is used to control the operation of the pet food automatic packaging machine.
