Detailed Embodiment

[0027] As Figures 1 to 5 shown, a multi-channel back-sealed bag lifting and transitional conveying device related to the present utility model includes a base 1 and a conveyor belt mechanism. Four floor feet 3 are symmetrically arranged on the base 1 near the four corners to facilitate the adjustment of its height; the conveyor belt mechanism includes an input conveyor belt 4 and an output conveyor belt 8. The input end of the output conveyor belt 8 and the output end of the input conveyor belt 4 overlap up and down and are respectively fixed on the base 1 through support arms 10; grooves are evenly distributed on the input conveyor belt 4 and the output conveyor belt 8 to facilitate the placement of one or a group of back-sealed bags and realize the step-by-step conveying of the back-sealed bags.

[0028] On the base 1, a power source 9 and a lifting box 5 are provided at the rear side of the conveyor belt mechanism. The power source 9 is in transmission connection with the lifting box 5 and is used to drive the lifting box 5 to reciprocate up and down. The lifting box 5 includes a lifting upper plate 501 and a lifting lower plate 502 arranged up and down. The lifting upper plate and the lifting lower plate 502 are fixedly connected by two symmetrically arranged square-ring-shaped support plates 503. Grooves are evenly distributed on the lifting upper plate 501 and the lifting lower plate 502 respectively, and correspond one by one to the grooves on the input conveyor belt 4 and the output conveyor belt 8.

[0029] On the base 1, two vertically arranged and rotatable lead screws 13 are symmetrically installed at both ends of the lifting box 5 through shaft seats 12 respectively. Two nuts 15 are symmetrically fixed at both ends of the lifting box 5 and are respectively in threaded connection with the corresponding lead screws 13. The power source 9 is preferably a servo motor and its output end is in transmission connection with the two lead screws 13 through a synchronous belt mechanism 14 to control the up and down reciprocating movement of the lifting box 5. The nuts 15 are fixed at both ends of the lifting lower plate 502, and two through holes are symmetrically provided at both ends of the lifting upper plate 501. The through holes correspond to the lead screws 13 one by one to facilitate the lifting of the lifting box 5.

[0030] On the base 1, a buffer platform 17 is fixed at the rear side of the lifting box 5 through two Z-shaped brackets 16 and is used to provide buffer transition during the lifting process of the back-sealed bag. Grooves are evenly distributed on the buffer platform 17 and correspond one by one to the grooves on the lifting upper plate 501 and the lifting lower plate 502.

[0031] When the lifting box 5 is in the lower position, the upper end surface of the lifting lower plate 502 is at the same height as the upper end surface of the input conveyor belt 4, and the upper end surface of the lifting upper plate 501 is at the same height as the upper end surface of the buffer platform 17. When the lifting box 5 is in the upper position, the upper end surface of the lifting lower plate 502 is at the same height as the upper end surface of the buffer platform 17, and the upper end surface of the lifting upper plate 501 is at the same height as the upper end surface of the output conveyor belt 8.

[0032] Push hands are respectively provided above and below the front side of the input conveyor belt 4, the rear side of the buffer platform 17 and both sides of the lifting box 5 and are used to push the back-sealed bag between the input conveyor belt 4, the lifting box 5, the buffer platform 17 and the output conveyor belt 8.

[0033] The pusher includes a first pusher 2, a second pusher 7, a third pusher 18 and a fourth pusher 6. The first pusher 2 is arranged on the front side of the input conveyor belt 4 and is fixedly supported on the base 1 through a first bracket 11, and is used to push the back-sealed bags on the input conveyor belt 4 onto the lifting lower plate 502; the second pusher 7 is arranged on the front side of the lifting box 5 and is fixedly supported on the base 1 through a second bracket (not shown in the figure), and is used to push the back-sealed bags on the lifting lower plate 502 onto the buffer platform 17; the third pusher 18 is arranged on the rear side of the buffer platform 17 and is fixedly supported on the Z-shaped bracket 16 of the buffer platform 17 through a third bracket (not shown in the figure), and is used to push the back-sealed bags on the buffer platform 17 onto the lifting upper plate 501; the fourth pusher 6 is arranged on the rear side of the upper dead point of the lifting box 5 and is fixedly supported on the Z-shaped bracket 16 of the buffer platform 17 through a fourth bracket (not shown in the figure), and is used to push the back-sealed bags on the lifting upper plate 501 onto the output conveyor belt 8.

[0034] The first pusher 2, the second pusher 7, the third pusher 18 and the fourth pusher 6 have the same structure, and each includes a trough-shaped push plate 20, a cylinder 19 and two guiding components 21. The cylinder 19 is connected to the middle of one side of the push plate 20, and the two guiding components 21 are symmetrically arranged on both sides of the cylinder 19, and one end of the guiding rod of the guiding component 21 is respectively connected to the push plate 20.

[0035] During operation, the specific working process is as follows:

[0036] 1. As Figure 4 shown, when the lifting box 5 is at the lower dead point position, the back-sealed bags in its groove are conveyed to the working area of the first pusher 2 by the input conveyor belt 4 and then paused. The controller controls the cylinder of the first pusher 2 to start, and pushes the back-sealed bags on the input conveyor belt 4 into the groove on the lifting lower plate 502, realizing the transfer and transition of the back-sealed bags from the input conveyor belt 4 to the lifting lower plate 502; then the first pusher 2 is controlled to reset.

[0037] 2. The controller controls the servo motor to start, drives the two lead screws 13 to rotate simultaneously through the synchronous belt mechanism 14, drives the lifting box 5 to rise to the upper dead point through the lead screw nuts 15, and then controls the second pusher 7 to start, and pushes and transfers the back-sealed bags on the lifting lower plate 502 into the groove on the buffer platform 17, realizing the transfer and transition of the back-sealed bags from the lifting lower plate 502 to the buffer platform 17, as Figure 5 shown; then the second pusher 7 is controlled to reset, and at the same time the input conveyor belt 4 continues to convey the back-sealed bags forward.

[0038] 3. Control the servo motor to start in reverse through the controller. When the lifting box 5 is driven by the synchronous belt mechanism 14 to descend to the lower dead center, repeat step 1. Push the back-sealed bag on the input conveyor belt 4 onto the groove on the lower lifting plate 502 again through the first pusher 2. At the same time, control the third pusher 18 to start, and push the back-sealed bag on the buffer platform 17 onto the groove on the upper lifting plate 501, so as to realize the transfer and transition of the back-sealed bag from the buffer platform 17 to the upper lifting plate 501. Then control the third pusher 18 to reset.

[0039] 4. Repeat step 2 to make the lifting box 5 rise to the upper dead center. Control the cylinder of the fourth pusher 6 to start through the controller, and push the back-sealed bag on the upper lifting plate 501 onto the groove on the output conveyor belt 8, so as to realize the transfer and transition of the back-sealed bag from the lifting box 5 to the output conveyor belt 8.

[0040] In summary, with each up-and-down reciprocating motion of the lifting box 5, a set of back-sealed bags is transferred and lifted once from the input conveyor belt 4 to the output conveyor belt 8 (that is, loading and unloading are each done once), so as to realize the intermittent continuous lifting and transitional transportation of the back-sealed bags from the input conveyor belt 4 to the output conveyor belt 8.

[0041] It should be noted that for the multi-channel back-sealed bag lifting and transitional transportation device involved in the present invention, the input conveyor belt 4 can also be arranged above the output conveyor belt 8, so as to form a multi-channel back-sealed bag descending and transitional transportation device, and realize the intermittent continuous descending and transitional transportation of the back-sealed bags from the input conveyor belt 4 to the output conveyor belt 8.

[0042] Although the embodiments of the present invention are disclosed as above, it is not limited to only the applications listed in the description and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, other modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
