[0029] Reference Figure 1 、 2 , 3, 4, and 5, the conveying device for cans according to the embodiment of the present invention includes a mounting base 100, a driving wheel 200, a driven wheel 300, a conveying chain plate 400, and a vacuum system (not shown in the figure), as shown in FIG. Figure 1 、 2 6, the mounting base 100 has a vacuum chamber 110 extending along the conveying direction of the tank body 500, and the top of the mounting base 100 has a first slide groove 120 connected to the vacuum chamber 110 and extending along the conveying direction of the tank body 500; Figure 1 、 3 As shown in , 4, and 5, the driving wheel 200 is rotatably mounted on one end of the mounting base 100 and is located outside the vacuum chamber 110; the driven wheel 300 is rotatably mounted on the other end of the mounting base 100 and is located outside the vacuum chamber 110; Figure 1 、 2 As shown in , 6, the conveying chain plate 400 is sleeved on the outside of the driving wheel 200 and the driven wheel 300, and the top part of the conveying chain plate 400 is movably provided on the first slide groove 120. The conveying chain plate 400 includes a plurality of unit plates 410 connected end to end, and the unit plates 410 have suction holes 420. When the unit plates 410 are located on the first slide groove 120, the suction holes 420 are connected to the vacuum chamber 110; the vacuum pumping system is connected to the vacuum chamber 110.

[0030] like Figure 1 As shown, the driving wheel 200 is driven to rotate, and the unit plate 410 of the conveying chain plate 400 can move along the first slide groove 120 of the mounting seat 100, and the cup suction hole 420 on the unit plate 410 can be connected to the vacuum chamber 110 in the mounting seat 100, and then the stretching machine 600 outputs multiple can bodies 500 to the mounting seat 100 and when the vacuum system is started, the multiple cup suction holes 420 of the multiple unit plates 410 can suck the multiple can bodies 500 and can drive the multiple can bodies 500 to move to the cutting machine 700; since the multiple unit plates 410 can suck the multiple can bodies 500, it can avoid the cans 500 from getting stuck or getting bumped when they move, thereby improving product quality, being able to run at a higher speed, and improving production efficiency.

[0031] The conveying device of the utility model can be used as an independent driving mechanism, has strong portability, is quick and convenient to install, and does not affect other equipment on the production line.

[0032] like Figure 1 As shown, the mounting seat 100 of the present invention is arranged between the outlet of the stretching machine 600 and the inlet of the notching machine 700. When working, the vacuum system is started to drive the driving wheel 200 to rotate, and the driving wheel 200 drives the conveying chain plate 400 to move. The top part of the conveying chain plate 400 moves along the first slide 120, and the stretching machine 600 conveys the can bodies 500 one by one to the unit plate 410 located on the top of the mounting seat 100. The multiple unit plates 410 successively absorb the can bodies 500 output one by one from the stretching machine 600 through the can suction holes 420. Since the multiple unit plates 410 move along the conveying direction of the can bodies 500 on the first slide 120, the can bodies 500 are conveyed to the notching machine 700 one by one.

[0033] Specifically, if Figure 3 As shown, when the mounting base 100 is viewed from above, the mounting base 100 is arc-shaped, and then the vacuum chamber 110 and the first slide groove 120 both extend along the arc, causing the tank body 500 to move in an arc as well.

[0034] In some embodiments, as Figure 6 As shown, the top portion of the conveying chain plate 400 is snap-connected with the first sliding groove 120 so that the top portion of the conveying chain plate 400 can move more stably.

[0035] Specifically, the side wall of the first sliding groove 120 has a recess, and a portion of the unit plate 410 is disposed in the recess. The recess is provided to guide the movement of the unit plate 410 .

[0036] like Figure 1 、 4 As shown in Figure 5, the conveying chain plate 400 includes an upper section 430, a lower section 440, a first arc section 450 and a second arc section 460. One end of the upper section 430 and one end of the lower section 440 are respectively connected to the two ends of the first arc section 450, and the other end of the upper section 430 and the other end of the lower section 440 are respectively connected to the two ends of the second arc section 460. The top part of the conveying chain plate 400 is the upper section 430.

[0037] In some embodiments of the present invention, Figure 2 、 6 As shown, the bottom of the mounting base 100 has a second chute 130 extending along the conveying direction of the tank 500. The bottom portion of the conveying chain plate 400 is movably mounted on the second chute 130, so that only the unit plate 410 is positioned outside the mounting base 100, making the vacuum conveyor more aesthetically pleasing. The bottom portion of the conveying chain plate 400 is the lower section 440.

[0038] In some embodiments, as Figure 6As shown, two guide assemblies 140 for guiding the movement of the tank body 500 are installed on the top of the mounting base 100. The two guide assemblies 140 are respectively located outside the left and right sides of the unit plate 410. The two guide assemblies 140 guide the movement of the tank body 500 and enable the unit plate 410 to more firmly absorb the tank body 500.

[0039] The guide assembly 140 may be a guardrail.

[0040] Since only two guide assemblies 140 are required, there is no need for baffles in the prior art, and no additional adjustments are required when converting tanks 500 of other lengths, which greatly improves the conversion efficiency and reduces downtime losses.

[0041] In some embodiments of the present invention, Figure 6 As shown, the guide assembly 140 includes a fixed part 141, a movable part 142 and a pulley 143 for guiding the movement of the tank body 500. The fixed part 141 is installed on the top of the mounting base 100, one end of the movable part 142 can be moved left and right and installed on the fixed part 141, and the pulley 143 can be rotatably installed on the other end of the movable part 142.

[0042] Since the movable portion 142 can be adjusted in the left and right directions, the interval between the two movable portions 142 can be adjusted, thereby being able to adapt to tank bodies 500 of different diameters; by providing a pulley 143, the tank body 500 can be positioned and guided to move.

[0043] In some embodiments, as Figure 7 As shown, it also includes a mounting plate 150, and the other end of the mounting seat 100 is provided with a slide plate 160 and a tensioning cylinder 170. The driven wheel 300 is rotatably mounted on the mounting plate 150, and the mounting plate 150 is movably mounted on the slide plate 160. The protruding end of the tensioning cylinder 170 is connected to the mounting plate 150, and the tensioning cylinder 170 is used to tension the conveying chain plate 400.

[0044] The tensioning cylinder 170 is provided so as to control the tension of the conveying chain plate 400 .

[0045] Specifically, the sliding plate 160 has a slideway, and a portion of the mounting plate 150 is slidably connected to the slideway.

[0046] In some embodiments, as Figure 7 As shown, the extended end of the tensioning cylinder 170 is detachably connected to the mounting plate 150 , and the driven wheel 300 is detachably connected to the mounting plate 150 , so that both the mounting plate 150 and the driven wheel 300 can be installed and removed.

[0047] Specifically, the protruding end of the tensioning cylinder 170 is threadedly connected to the mounting plate 150 , and the driven wheel 300 is fixed to the mounting plate 150 by screws.

[0048] In some embodiments, as Figure 2 As shown, one side of the mounting base 100 has a vacuum exhaust port 180 communicating with the vacuum chamber 110 . The vacuum exhaust port 180 is connected to a vacuum pumping system to make it easier for the vacuum chamber 110 to communicate with the vacuum pumping system.

[0049] In some embodiments, as Figure 1 As shown, a reduction motor 190 is further included, which is connected to the driving wheel 200. The reduction motor 190 is provided to control the conveying speed of the conveying chain plate 400.

[0050] In some embodiments of the present invention, Figure 1 As shown, the portion where the first sliding groove 120 and the unit plate 410 are engaged is made of nylon material to increase the service life of the unit plate 410 .
