[0035] See also Figure 1-12 The present invention provides an automatic stacking device for a baler, comprising a support assembly 1 and a conveying assembly 2, wherein the conveying assembly 2 is connected to a workbench 9, a controller 101 is connected to the upper surface of the workbench 9, the support assembly 1 is connected to a detection assembly 6, two placement assemblies 7 are arranged in the support assembly 1, the conveying assembly 2 is connected to a pushing assembly 4 through two transmission assemblies 3, and the support assembly 1 is connected to a positioning assembly 5 through a movable assembly 8;

[0036] The support assembly 1 includes a support frame 11, and the conveying assembly 2 includes a conveying frame 21. Two conveying rollers 22 are rotatably connected in the conveying frame 21. The two conveying rollers 22 are connected by a conveying belt 23. A push plate 24 is connected to the conveying belt 23.

[0042] In this embodiment, by setting the slider 13 and the slide groove 12, since the slider 13 is slidably connected in the slide groove 12, the slider 13 and the slide groove 12 cooperate with each other to limit the movable plate 41, so that the movable plate 41 will not be moved when moving, so that the movable plate 41 can move smoothly in the support frame 11; by setting the positioning bar 14, when the movable plate 41 moving downward contacts the positioning bar 14, the positioning bar 14 can limit and fix the movable plate 41 at a position flush with the conveyor belt 23;

[0044] In this embodiment, by providing a guide rod 33, the guide rod 33 can limit the tooth plate 32, so that the tooth plate 32 can always be meshed with the gear 31, and the rotating gear 31 can drive the tooth plate 32 to move along the axial direction of the guide rod 33;

[0045] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, an automatic stacking device for a baler provided by the present invention is provided. First electric push rods 44 are clamped in two cavities 43. The bottom ends of the two first electric push rods 44 are connected to limiting plates 45. The shape of the movable plate 41 is set to be L-shaped.

[0046] In this embodiment, the movable plate 41 is provided. Since the shape of the movable plate 41 is set to be L-shaped, the L-shaped movable plate 41 can limit the plate moving above it, so that the plate is not easily pushed down from the side of the movable plate 41 away from the conveyor belt 23, and the plate moving onto the movable plate 41 can also squeeze the multiple pressure sensors 10 on the side thereof. When the multiple pressure sensors 10 all feel the pressure, the plate moves accurately onto the movable plate 41.

[0047] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7and Figure 8 As shown, an automatic stacking device for a baler provided by the present invention is provided. The positioning assembly 5 includes a piston cylinder 51. Both sides of the piston cylinder 51 are connected to the bottom ends of two second connecting tubes 53 through a first connecting tube 52, respectively. The two second connecting tubes 53 are connected to a plurality of telescopic assemblies 55 through a plurality of hoses 54, respectively. The adjacent ends of the plurality of telescopic assemblies 55 are connected to two first positioning plates 56 and two second positioning plates 57, respectively. The adjacent surfaces of the two first positioning plates 56 and the two second positioning plates 57 are rotatably connected with a first roller 58, and the bottoms of the two second positioning plates 57 are rotatably connected with a second roller 59. A piston plate 510 is slidably connected in the piston cylinder 51. Two piston rods 511 are connected to the upper surface of the piston plate 510. The two piston rods 511 are slidably connected in the piston cylinder 51. Second electric push rods 512 are clamped in the two piston rods 511, and the top ends of the two second electric push rods 512 are clamped at the bottom of the first sliding rod 46.

[0048] In this embodiment, the first sliding rod 46 moving downward drives the piston plate 510 to move downward in the piston cylinder 51 through the second electric push rod 512 and the piston rod 511, and the gas below the piston plate 510 enters the plurality of telescopic components 55 through the two first connecting pipes 52, the two second connecting pipes 53 and the plurality of hoses 54, respectively, so that the plurality of telescopic components 55 are extended, and the plurality of extended telescopic components 55 respectively drive the two first positioning plates 56 and the two second positioning plates 57 to approach each other, so that the mutually approaching first positioning plates 56 gradually contact the plates moving between them, so that the two ... The first positioning plate 56 positions the plate in the middle position of the conveyor belt 23, and the telescopic assembly 55 is composed of a slide cylinder, a movable rod and a spring. The slide cylinder is connected to the hose 54, the movable rod is connected to the second positioning plate 57, and the slide cylinder is clamped in the movable bar 82, the movable rod is slidably connected in the slide cylinder, the spring is arranged in the slide cylinder, and the spring is sleeved on the outside of the movable rod. When the piston plate 510 moves downward in the piston cylinder 51, the gas entering the slide cylinder through the hose 54 will push the movable rod to extend out of the slide cylinder, and the spring will stretch. When the piston plate 510 moves upward in the piston cylinder 51, the movable rod will retract into the slide cylinder under the action of the spring force.

[0049] like Figure 2 , Figure 6 and Fig.11As shown, an automatic stacking device for a baler provided by the present invention is provided. The detection component 6 includes a fixed frame 61, the bottom end of the fixed frame 61 is connected to the support frame 11, the upper surface of the fixed frame 61 is connected to a protective cover 62, two second slide bars 63 are slidably connected inside the fixed frame 61, the bottom ends of the two second slide bars 63 are connected to the same wedge plate 64, the two second slide bars 63 are both sleeved with a first spring 65, the two ends of the first spring 65 are respectively connected to the wedge plate 64 and the fixed frame 61, the top ends of the two second slide bars 63 are connected to the same connecting plate 66, the bottom of the connecting plate 66 is clamped with a laser sensor 67, and the upper surface of the fixed frame 61 is provided with a receiver 68, and the receiver 68 is arranged directly below the laser sensor 67.

[0050] In this embodiment, when the plate moves into the detection assembly 6 under the action of the moving push plate 24 and contacts the wedge plate 64, the plate pushed by the push plate 24 slowly pushes the wedge plate 64 to move upward, and the upwardly moving wedge plate 64 drives the laser sensor 67 to move upward through the guide rod 33 and the connecting plate 66. When the lower surface of the wedge plate 64 contacts the upper surface of the plate, the distance between the laser sensor 67 and the receiver 68 is the maximum, and the distance is the thickness of the plate. Then, the data detected by the laser sensor 67 is controlled by the controller 101. An electric push rod 44 works, so that the working first electric push rod 44 drives the limit plate 45 to move in the cavity 43, so as to control the stroke of the first slide rod 46 in the cavity 43, so that the upward pushing pushing component 4 can accurately adjust the upward movement distance of the movable plate 41 according to the thickness of the plate, so that the pushing component 4 is not likely to move too low, resulting in the plate being unable to move smoothly to the stacking position, or the pushing component 4 is not likely to move too high, resulting in time wasted due to the extra movement distance, which further improves the stacking efficiency of the device for the plates.

[0051] like Figure 2 , Figure 4 and Figure 8 As shown, an automatic stacking device for a baler provided by the present invention, the movable component 8 includes two limit rods 81, the two limit rods 81 are both connected to the support frame 11, the two limit rods 81 are slidably connected to the same movable bar 82 outside, wherein a plurality of telescopic components 55 are clamped in the movable bar 82, the limit rods 81 are externally connected to a second spring 83, and the two ends of the second spring 83 are respectively connected to the support frame 11 and the movable bar 82.

[0052] In this embodiment, when the movable plate 41 moving upward drives the plate to move upward, the second positioning plates 57 moving away from each other may be located above the movable plate 41, so that the movable plate 41 moving upward will contact the second roller 59, and at this time the movable plate 41 continues to move upward, and the two second positioning plates 57 continue to move away from each other. In this process, the two second positioning plates 57 moving away from each other both drive the second rollers 59 moving away from each other on the movable plate 41. At this time, the movable plate 41 moving upward will drive the movable bar 82 to slide upward outside the two limit rods 81 through the second rollers 59, the second positioning plate 57 and the telescopic assembly 55, and the movable bar 82 moving upward drives the two second springs 83 to extend, so that the two second positioning plates 57 moving away from each other gradually move away from above the movable plate 41, and then the movable bar 82 drives the second positioning plate 57 to move to a position flush with the first positioning plate 56 through the telescopic assembly 55 under the action of the elastic force of the two extended second springs 83.

[0053] The working principle and use process of the present invention are as follows: when the device needs to be used, the external motor is connected to one of the conveying rollers 22. When the push plate 24 of the reversed conveyor belt 23 moves to the top of the gear 31, the external cylinder can push the plate from the workbench 9 on one side of the conveyor frame 21 to the conveyor belt 23, and then the external motor is controlled to drive the conveyor belt 23 to rotate forward through the conveyor roller 22. The forward-rotating conveyor belt 23 moves toward the direction of the movable plate 41 through the push plate 24. At the same time, the rotating conveyor roller 22 drives the gear 31 to rotate synchronously. The rotating gear 31 drives the tooth plate 32 to slide outside the two guide rods 33. The two moving tooth plates 32 both drive the pushing assembly 4 to move downward through the push rod 34. The movable plate 41 moving downward gradually contacts the two positioning bars 14, and then the conveyor belt 23 continues to rotate. At the same time, the moving tooth plate 32 continues to drive the first slide bar 46 to slide downward in the cavity 43 through the push rod 34.

[0054] The first sliding rod 46 moving downward drives the piston plate 510 to move downward in the piston cylinder 51 through the second electric push rod 512 and the piston rod 511. The gas below the piston plate 510 enters the plurality of telescopic components 55 through the two first connecting pipes 52, the two second connecting pipes 53 and the plurality of hoses 54, respectively, so that the plurality of telescopic components 55 are extended. The plurality of extended telescopic components 55 respectively drive the two first positioning plates 56 and the two second positioning plates 57 to approach each other, so that the mutually approaching first positioning plates 56 gradually contact the plates moving between them. , so that the two first positioning plates 56 close to each other position the plate in the middle of the conveyor belt 23, and the plate pushed by the push plate 24 gradually moves to between the two second positioning plates 57. When the moving plate contacts the plurality of pressure sensors 10, the plate is accurately positioned on the piston plate 510. When the plurality of pressure sensors 10 detect signals, the external motor reverses, and the conveyor belt 23 drives the push plate 24 to a position away from the support frame 11, and slowly moves to the initial position. In this process, the rotating conveyor roller 22 passes through the gear The wheel 31, the tooth plate 32 and the push rod 34 drive the first slide bar 46 to move upward, and the first slide bar 46 moving upward drives the piston plate 510 to move upward in the piston chamber through the second electric push rod 512 and the piston rod 511. At this time, the gas in the plurality of telescopic components 55 moves into the piston cylinder 51 through the hose 54, the second connecting pipe 53 and the first connecting pipe 52. At the same time, when the first slide bar 46 moving upward contacts the limit plate 45, the first slide bar 46 moving upward can synchronously drive the movable plate through the limit plate 45, the first electric push rod 44 and the connecting frame 42 41 moves upward, so that the movable plate 41 moving upward drives the plate to move upward and contact the two placement blocks 73. The two inclined placement blocks 73 drive the rotating plate 75 to rotate in the limiting groove 76 under the push of the upward moving plate. When the upward moving plate moves to the top of the placement blocks 73, the two placement blocks 73 are reset to the initial position under the torsion of the two torsion springs 74. At this time, the two placement blocks 73 are located below the plate, and the push plate 24 moves to the top of the gear 31, and then the plate on the workbench 9 is repeatedly pushed onto the conveyor belt 23.

[0055] When the plate moves into the detection assembly 6 under the action of the moving push plate 24 and contacts the wedge plate 64, the plate pushed by the push plate 24 slowly pushes the wedge plate 64 to move upward, and the upwardly moving wedge plate 64 drives the laser sensor 67 to move upward through the guide rod 33 and the connecting plate 66. When the lower surface of the wedge plate 64 contacts the upper surface of the plate, the distance between the laser sensor 67 and the receiver 68 is the maximum, and the distance is the thickness of the plate. Then the data detected by the laser sensor 67 controls the first electric push rod 44 to work through the controller 101, so that the working first electric push rod 44 drives the limit plate 45 to move in the cavity 43, thereby controlling The first electric push rod 44 is extended, and the extended first electric push rod 44 drives the limit plate 45 to move downward, thereby reducing the stroke of the first slide rod 46 in the cavity 43, so that the first slide rod 46 moving upward only needs to move a small distance to synchronously drive the movable plate 41 to move upward through the limit plate 45, the first electric push rod 44 and the connecting frame 42. On the contrary, when the thickness of the plate is small, the contracted first electric push rod 44 drives the limit plate 45 to move upward in the cavity 43;

[0056] The staff can adjust the distance between the two first positioning plates 56 according to the width of the plate. When the width of the plate is narrow, the second electric push rod 512 extends, so that the first slide bar 46 moving downward can drive the piston plate 510 to move a larger distance in the piston cylinder 51 through the second electric push rod 512 and the piston rod 511, so that several first positioning plates 56 and several second positioning plates 57 can be synchronously moved closer, so as to position the narrower plate. On the contrary, when the plate is wider, the second electric push rod 512 contracts to reduce the distance between the first slide bar 46 and the piston rod 511.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
