[0011] On the basis of the above solution: The clamping and lifting mechanism includes a Z-shaped cover plate, a Z-shaped guide rail, a rotating shaft, a flexible clamping plate and a transmission belt. The bottom of the Z-shaped cover plate is fixedly connected to the top of the moving plate. The rotating shaft is rotatably connected to the inner sides of both ends of the Z-shaped cover plate, and the Z-shaped guide rail is fixedly connected to the inside of the Z-shaped cover plate.

[0012] In the above solution, a better solution is as follows: The transmission belt is drivingly connected to the circumference of the rotating shaft through a transmission wheel. The flexible clamping plates are fixedly connected to the outer circumference of the transmission belt at equal intervals, and the flexible clamping plates form a sliding fit with the Z-shaped guide rail. The output end of the servo motor is connected to the bottom end of the rotating shaft through a coupling.

[0013] As a further solution of the present invention: The flexible clamping plate includes a sliding block, a limiting groove, a rubber clamping strip, a sealing plate, a movable block and a limiting block.

[0014] Meanwhile, the movable block is telescopically connected to one side of the sliding block. The sealing plate is adhesively connected to both sides of the sliding block. The rubber clamping strip is arranged on one side of the movable block. The limiting blocks are fixedly connected to the top and the bottom of the movable block.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For this automatic clamping and conveying device for packaging boxes, by starting the servo motor to drive the rotation of the rotating shaft, the rotating shaft drives the transmission belt to work, and then drives multiple groups of flexible clamping plates on the outer circumference of the transmission belt to move around the Z-shaped guide rail. The packaging boxes are clamped by the opposite flexible clamping plates and lifted and transported along the Z-shaped guide rail. Thus, the function of lifting the packaging box from one position to another is realized, the problem of manual handling is solved, the labor cost is reduced. At the same time, through the clamping and lifting of the packaging boxes, the separation of processes in the production workshop is realized, the ground space is saved, and the warehousing efficiency is improved.

[0020] 2. The automatic clamping and conveying device for a packaging box drives the rotating plate to rotate by starting the stepping motor. The rotating rotating plate drives the guide rod to rotate. The rotating guide rod pulls the sliding ring at its end to slide towards the center of the rotating plate in the chute, thereby driving the adjustment of the distance between both ends of the clamping and lifting mechanism. Thus, the clamping and transportation requirements of packaging boxes of different specifications are met, and the function of adjusting the clamping distance of the packaging box is realized.

[0021] 3. The automatic clamping and conveying device for a packaging box has the sliding block slidably connected to the Z-shaped guide rail through the limiting groove. When the packaging box enters between the two Z-shaped cover plates, it is clamped on both sides by the rubber clamping strips. During this period, the movable block slides on the guide strip, and during the clamping of the packaging box, the spring inside the U-shaped flexible plate expands and contracts to drive the swing rod to swing, realizing the stretching of the U-shaped flexible plate, so that the rubber clamping strip on one side of the movable block realizes the function of clamping with different forces, effectively meeting the clamping requirements of irregular packaging boxes and improving the stability of clamping and lifting of the packaging box.

On the opposite sides of the top of the frame 1, a guide shaft 11 is fixedly connected. The top of the guide shaft 11 is slidably connected with a clamping and lifting mechanism 10. An adjusting mechanism 2 is arranged on the outer wall of the frame 1 near the lower part of the guide shaft 11. One side of the top of the clamping and lifting mechanism 10 is fixedly connected with a limiting plate 6 through a bracket 9. One side of the end of the limiting plate 6 is fixedly provided with an infrared sensor 5 by bolts. One side of the back of the top of the clamping and lifting mechanism 10 is slidably connected with a baffle 7. A material guiding plate 8 is fixedly connected to the outer wall of the clamping and lifting mechanism 10 above the baffle 7. The bottom outer wall of the end of the clamping and lifting mechanism 10 is fixedly connected with a servo motor 3 through a support plate. The output end of the servo motor 3 is in transmission connection with the driving end of the clamping and lifting mechanism 10. The model of the infrared sensor 5 is E18-D80NK.

[0035] To realize the function of adjusting the clamping distance of the packaging box; as Figure 4 shown in Figure 4 , the adjusting mechanism 2 includes a mounting plate 201, a mounting shaft 202, a guide rod 203, a rotating plate 204, a sliding ring 205, a sliding groove 206 and a stepping motor 207. The mounting plate 201 is fixedly connected to the outer wall of the frame 1 near the lower part of the guide shaft 11 by bolts. The stepping motor 207 is fixedly connected to the bottom of the mounting plate 201 through a support plate. The rotating plate 204 is threadedly connected to the circumference of the output end of the stepping motor 207. The guide rods 203 are respectively rotatably connected to both ends of the top of the rotating plate 204. The sliding ring 205 is rotatably connected to one end of the guide rod 203 away from the rotating plate 204. The sliding grooves 206 are opened on both outer walls of the top of the mounting plate 201. The sliding ring 205 forms a sliding fit with the sliding grooves 206. The mounting shaft 202 is threadedly connected to the top outer wall of the sliding ring 205. The top end of the mounting shaft 202 is threadedly connected with a moving plate 4. The moving plate 4 forms a sliding fit with the guide shaft 11. The moving plate 4 is connected to one side of the bottom of the clamping and lifting mechanism 10.

[0036] During operation, the stepping motor 207 is started to drive the rotating plate 204 to rotate. The rotating rotating plate 204 drives the guide rod 203 to rotate. The rotating guide rod 203 pulls the sliding ring 205 at its end to slide towards the center of the rotating plate 204 in the sliding groove 206, thereby driving the adjustment of the distance between the two ends of the clamping and lifting mechanism 10. Thus, the clamping and transportation requirements of packaging boxes of different specifications are met, and the function of adjusting the clamping distance of the packaging box is realized.

[0037] To promote the clamping, lifting and transportation of the packaging box; as Figure 1As shown, the clamping and lifting mechanism 10 includes a Z-shaped cover plate 1001, a Z-shaped guide rail 1002, a rotating shaft 1003, a flexible clamping plate 1004, and a transmission belt 1005. The bottom of the Z-shaped cover plate 1001 is fixedly connected to the top of the moving plate 4. The rotating shaft 1003 is rotatably connected to the inner sides of both ends of the Z-shaped cover plate 1001. The Z-shaped guide rail 1002 is fixedly connected to the inside of the Z-shaped cover plate 1001. The transmission belt 1005 is connected to the circumference of the rotating shaft 1003 through a transmission wheel. The flexible clamping plates 1004 are fixedly connected to the outer circumference of the transmission belt 1005 at equal intervals, and the flexible clamping plates 1004 form a sliding fit with the Z-shaped guide rail 1002. The output end of the servo motor 3 is connected to the bottom end of the rotating shaft 1003 through a coupling;

[0038] By starting the servo motor 3 to drive the rotation of the rotating shaft 1003, the rotating rotating shaft 1003 drives the transmission belt 1005 to work, and then drives multiple groups of flexible clamping plates 1004 on the outer circumference of the transmission belt 1005 to move around the Z-shaped guide rail 1002. The packaging box is clamped by the opposite flexible clamping plates 1004 and lifted and transported along the Z-shaped guide rail 1002. Thus, the function of lifting the packaging box from one position to another is realized, the problem of manual handling is solved, the labor cost is reduced. At the same time, through the clamping and lifting of the packaging box, the separation of processes in the production workshop is realized, the ground space is saved, and the warehousing efficiency is improved.

[0039] To promote high stability in clamping the packaging box; as Figure 5 , Figure 6 and Figure 7 shown, the flexible clamping plate 1004 includes a sliding block 10041, a limiting groove 10042, a rubber clamping strip 10043, a sealing plate 10044, a movable block 10045, and a limiting block 10046. The sliding block 10041 is slidably connected to one side of the Z-shaped guide rail 1002. The limiting groove 10042 is opened on one side of the top and one side of the bottom of the sliding block 10041, and the limiting groove 10042 forms a sliding fit with the Z-shaped guide rail 1002. The movable block 10045 is telescopically connected to one side of the sliding block 10041. The sealing plate 10044 is bonded to both sides of the sliding block 10041. The rubber clamping strip 10043 is arranged on one side of the movable block 10045. The limiting block 10046 is fixedly connected to the top and bottom of the movable block 10045;

[0040] One side inside the sliding block 10041 is fixedly connected with a partition plate 100443, and guide bars 100441 are fixedly connected to both sides of the sliding block 10041 close to the partition plate 100443. The guide bars 100441 form a sliding fit with the movable block 10045. A storage groove 100444 is opened on the opposite sides of the sliding block 10041 and the movable block 10045, and a telescopic component 100442 is fixedly connected to the inner wall of the opposite side of the storage groove 100444;

[0041] The telescopic assembly 100442 includes a U-shaped flexible plate 1004421, a fixed block 1004422, a fixed seat 1004423, a swing rod 1004424 and a spring 1004425. The U-shaped flexible plate 1004421 is fixedly connected to the storage groove 100444. The fixed block 1004422 is fixedly connected to one side of the inner wall of the U-shaped flexible plate 1004421. The spring 1004425 is fixedly connected to the top of the fixed block 1004422. The fixed seat 1004423 is fixedly connected to the top end of the spring 1004425. The swing rod 1004424 is rotatably connected to the inner shaft of the fixed seat 1004423, and the other end of the swing rod 1004424 is connected to the inner walls on both sides of the U-shaped flexible plate 1004421.

[0042] The sliding block 10041 is slidably connected to the Z-shaped guide rail 1002 through the limit groove 10042. When the packaging box enters between the two Z-shaped cover plates 1001, both sides of it are clamped by the rubber clamping strips 10043. During this period, the movable block 10045 slides on the guide bar 100441. And during the clamping process of the packaging box, the spring 1004425 inside the U-shaped flexible plate 1004421 expands and contracts to drive the swing rod 1004424 to swing, realizing the stretching of the U-shaped flexible plate 1004421, so that the rubber clamping strips 10043 on one side of the movable block 10045 achieve the clamping function with different forces, effectively meeting the clamping requirements of irregular packaging boxes and improving the stability of the clamping and lifting of the packaging box.

[0043] Working principle: By starting the servo motor 3 to drive the rotating shaft 1003 to rotate, the rotating rotating shaft 1003 drives the transmission belt 1005 to work, and then drives multiple groups of flexible clamping plates 1004 on the outer periphery of the transmission belt 1005 to move around the Z-shaped guide rail 1002. The packaging box is clamped by the opposite flexible clamping plates 1004 and is lifted and transported along the Z-shaped guide rail 1002;

[0044] During this period, by starting the stepper motor 207 to drive the rotating plate 204 to rotate, the rotating rotating plate 204 drives the guide rod 203 to rotate. The rotating guide rod 203 pulls the sliding ring 205 at its end to slide towards the center of the rotating plate 204 in the chute 206, thereby driving the adjustment of the distance between the two ends of the clamping and lifting mechanism 10;

[0045] The sliding block 10041 is slidably connected to the Z-shaped guide rail 1002 through the limit groove 10042. When the packaging box enters between the two Z-shaped covers 1001, its two sides are clamped by the rubber clamping strips 10043. During this period, the movable block 10045 slides on the guide bar 100441. And during the clamping process of the packaging box, the spring 1004425 inside the U-shaped flexible plate 1004421 expands and contracts to drive the swing rod 1004424 to swing, realizing the stretching of the U-shaped flexible plate 1004421, so that the rubber clamping strip 10043 on one side of the movable block 10045 realizes the clamping function with different forces.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
