Description

Technical Field

[0001] The invention belongs to the technical field of bagged food packaging machines, and in particular relates to a packaging machine with food conveying. Background Art

[0002] In the food production process, conveyors and packaging machines are often used, such as the patent application number 201710006375.2 and named a cup food packaging equipment and packaging method. In the transmission process of bagged food packaging, the following problems are often encountered: Use a robotic arm to assist in transferring bagged food from one conveyor belt to another, such as Fig.26 As shown, the bagged foods are evenly spaced on conveyor belt A and move from conveyor belt A to conveyor belt B. When the bagged foods reach conveyor belt B under the drive of conveyor belt A, a robotic arm is required to simultaneously transfer two adjacent bagged foods from conveyor belt A to conveyor belt B in a parallel state. Conveyor belt B transfers the two parallel bagged foods to the next process and finally completes the packaging of the two bagged foods in one packaging box. The transfer of bagged foods from conveyor belt A to conveyor belt B is achieved by using a robotic arm, which results in a higher overall equipment cost.

[0003] There are two ways to put the bagged food on the conveyor belt into the packaging box. One is to use the ordinary push method, and the other is to use a robot arm. The method of using a robot arm to put the bagged food into the packaging box can achieve a more complicated bagged food box-into-box action, but the equipment cost is higher. The ordinary push method of putting the bagged food into the packaging box is easier to complete the bagged food into the packaging box in a single layer state, but it is not easy to complete the bagged food into the packaging box in a stacked state. Fig. 27 As described above, when two or more layers of bagged food need to be loaded into a packaging box, after the first layer of bagged food is pushed into the packaging box, the height of the packaging box needs to be adjusted so that the height of the packaging box is lowered by the height of one layer of bagged food relative to the conveyor belt. This ensures that the second layer of bagged food can be smoothly pushed in and stacked on the first layer of bagged food in the packaging box. However, the relevant structure of the packaging box does not support the up and down movement of the packaging box or it is difficult to achieve up and down movement.

[0004] The present invention designs a packaging machine with food conveying to solve the above problems. Summary of the invention

The present invention cooperates with the boxing component and the third conveyor belt component to lift and align the single-layer bagged food at a specific position on the third conveyor belt relative to the box opening of the packaging box, and pushes the lifted single-layer bagged food horizontally layer by layer into the packaging box for boxing.

The bending degree of the elastic arc plate 315 in the clamping assembly 310 between the two second guide strips 317 is greater than the bending degree of the elastic arc plate 315 in the clamping assembly 310 between the two second guide strips 318, the two first top plates 319 are both in a docking state with the first guide strips 317 on the corresponding side, and the roller 314 on the column 313 in the clamping assembly 310 between the two first top plates 319 is against the first top plate 319, and the bending degree of the elastic arc plate 315 in the clamping assembly 310 between the two first top plates 319 is the same as the bending degree of the elastic arc plate 315 between the two first guide strips 317. The second slide 425 corresponding to the third transmission roller 403 of the transmission terminal in the third transmission assembly 400 is located at the extreme position of the slide slot 428 under the action of the pressure spring 427, and the upper and lower parts of the third transmission belt 412 are in a straight state. The second top plate 604 in the box packing assembly 600 abuts against the third conveyor belt 412 , the pushing slat 607 is located on one side of the third conveyor belt 412 , and the lower surface of the fourth conveyor belt 608 is flush with the upper belt surface of the third conveyor belt 412 .

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, when the present invention is needed to package the bagged food 104 into the packaging box 103, the first motor 211, the second motor 307, and the third motor 404 are started, the first motor 211 drives the first conveyor belt 205 to move through the second pulley 210, the first synchronous belt 209, the first pulley 208, the first roller 202 and the first transmission roller 203, the second motor 307 drives the second conveyor belt 309 to move through the fourth pulley 306, the second synchronous belt 305, the third pulley 304, the second roller 302 and the second transmission roller 303, and the third motor 404 drives the third conveyor belt 412 to move through the third roller 402 and the third transmission roller 403.

[0041] The first conveyor belt 205 drives the bagged foods 104 placed thereon at intervals to move quickly and enables the bagged foods 104 to reach the two clamping assemblies 310 on the second conveyor belt 309 of the second conveyor assembly 300 under the action of inertia. The second side guard 316 between the two clamping assemblies 310 enables the bagged foods 104 that arrive between the two clamping assemblies 310 on the second conveyor belt 309 at high speed to be positioned on the center line of the second conveyor belt 309. The front and rear sides of the bagged foods 104 that have just arrived between the two clamping assemblies 310 on the second conveyor belt 309 are spaced apart from the corresponding side elastic arc plates 315 of the corresponding two clamping assemblies 310 and are not clamped and fixed by the two clamping assemblies 310.

[0042] When the clamping assemblies 310 on both sides of the bagged food 104 on the second conveyor belt 309 pass between the two second guide strips 318 and arrive between the two first guide strips 317, the rods 313 in the two clamping assemblies 310 move toward each other under the action of the two first guide strips 317 and compress and bend the corresponding two elastic arc plates 315, and the corresponding side elastic arc plates 315 of the clamping assemblies 310 on both sides of the bagged food 104 between the two clamping assemblies 310 clamp and fix the bagged food 104. The bagged food 104 clamped and fixed by the elastic arc plates 315 in the two clamping assemblies 310 follows the conveyor belt around the second conveying roller 303 of the conveying terminal to arrive between the two second top plates 604 and is still clamped and fixed under the action of the two second top plates 604. At this time, the rear side clamping assembly 310 of the adjacent bagged food 104 at the rear is still located between the two first guide strips 317 and together with the front clamping assembly 310, the bagged food 104 at the corresponding position is in a clamped and fixed state.

[0043] At this time, the two first electric push rods 320 are started to drive the two second top plates 604 to move away from each other and release the pressure on the two clamping assemblies 310 located therebetween. The two pillars 313 of the two clamping assemblies 310 located between the two second top plates 604 slide back and reset under the resetting action of the corresponding elastic arc plates 315 and release the clamping and fixation of the corresponding bagged foods 104. The bagged foods 104 at adjacent positions also lose the clamping and fixation of the corresponding two clamping assemblies 310 due to the resetting of the elastic arc plates 315 of the clamping assemblies 310 in front of them. The two adjacent bagged foods 104 fall down by their own weight without being clamped and fixed by the clamping assemblies 310 to between the two positioning strips 414 of the corresponding positioning assemblies 423 on the third conveyor belt 412 below.

[0044] like Figure 5 , Fig.28As shown, when two bagged foods 104 located in the same positioning assembly 423 reach the position between the two third support slats 422 driven by the third conveyor belt 412, the third motor 404 is stopped and the third conveyor belt 412 stops moving, so that the two bagged foods 104 located between the two third support plates are horizontally opposite to the pushing slats 607 in the box assembly 600 and the box opening of the packaging box 103 on the packaging device.

[0045] Next, the fourth motor 611 is started, and the fourth motor 611 drives the fourth conveyor belt 608 to move through the fourth roller 609 and the fourth conveying roller 610, and the third electric push rod 605 is started, and the third electric push rod 605 drives the fourth conveyor belt 608 to move toward the bottom of the bagged food 104 on the third conveyor belt 412 through the second support 606. When the push slat 607 drives the fourth conveyor belt 608 to reach the bottom of the bagged food 104, the fourth conveyor belt 608 moving relative to the push slat 607 will sequentially transfer the two bagged foods 104 to the push slat 607. When the two bagged foods 104 just arrive at the push slat 607, the third conveyor belt 608 is stopped. The fourth motor 611 runs, thereby stopping the movement of the fourth conveyor belt 608, starting the third electric push rod 605 to drive the two bagged foods 104 to be horizontally fed into the paper packaging box 103 through the pushing slat 607, and then, starting the fourth motor 611 in reverse, the fourth motor 611 drives the fourth conveyor belt 608 to move in reverse through a series of transmissions and pushes the two bagged foods 104 on it into the packaging box 103, at the same time, the third electric push rod 605 drives the pushing slat 607 to move out of the packaging box 103 and reset, and when the pushing slat 607 drives the fourth conveyor belt 608 to leave the packaging box 103, the two bagged foods 104 just fall to the bottom of the packaging box 103.

[0046] Then, when the next pair of adjacent bagged foods 104 reaches the position relative to the boxing assembly 600, the second electric push rod 603 is started to drive the second top plate 604 on the first support 602 to move upward, and the second top plate 604 drives the corresponding position of the third conveyor belt 412 to move upward. The two sides of the third conveyor belt 412 are always in a horizontal state under the limitation of the second limiting strips 418 and the third limiting strips 419. As the corresponding part of the third conveyor belt 412 is lifted under the top delivery of the second top plate 604, the two bagged foods 104 at the corresponding positions are lifted synchronously, and the third conveyor belt 412 pulls the third conveying roller 403 of the transmission terminal in the third transmission assembly 400 to move horizontally. The moving third conveying roller 403 drives the two second slides 425 through the corresponding third roller shaft 402 to synchronously compress the two pressure springs 427, and the two first telescopic rods 426 shrink.

[0047] When the two lifted bagged foods 104 reach the position between the top of the packaging box 103 and the top of the bagged foods 104 therein, the fourth motor 611 is started again, and the fourth motor 611 drives the fourth conveyor belt 608 to move through the fourth roller 609 and the fourth conveying roller 610, and the third electric push rod 605 is started, and the third electric push rod 605 drives the fourth conveyor belt 608 to move toward the bottom of the bagged foods 104 on the third conveyor belt 412 through the second support 606. When the pushing slat 607 drives the fourth conveyor belt 608 to reach the bottom of the bagged foods 104, the fourth conveyor belt 608 moving relative to the pushing slat 607 will sequentially transfer the two bagged foods 104 to the pushing slat 607. When the two bagged foods 104 just reach the pushing slat 607, the fourth conveyor belt 608 is stopped. The motor 611 runs, thereby stopping the movement of the fourth conveyor belt 608, starting the third electric push rod 605 to drive the two bagged foods 104 to be horizontally fed into the paper packaging box 103 through the pushing slat 607 and stacked on the previously placed bagged foods 104, then, starting the fourth motor 611 in reverse, the fourth motor 611 drives the fourth conveyor belt 608 to move in reverse through a series of transmissions and pushes the two bagged foods 104 on it into the packaging box 103, at the same time, the third electric push rod 605 drives the pushing slat 607 to move out of the packaging box 103 and reset, when the pushing slat 607 drives the fourth conveyor belt 608 to leave the packaging box 103, the two bagged foods 104 just fall on the previously placed bagged foods 104, thus completing the stacking packaging of the bagged foods 104 in one packaging box 103.

[0048] During the movement of the third conveyor belt 412, the first gear 501 on the third roller 402 drives the two pressure wheels 506 to rotate synchronously and continuously maintain pressure on the third conveyor belt 412 through the second gear 502, the third gear 503, the fourth gear 504 and the rotating shaft 505, to ensure that the transmission starting end of the third conveyor belt 412 will not move under the top action of the second top plate 604 and only the transmission terminal end of the third conveyor belt 412 will move accordingly.
