Description

Technical Field

[0001] This invention relates to the field of stacker technology, and more particularly to an automatic cardboard box stacker. Background Technology

[0002] In the fields of cardboard packaging and logistics warehousing, automated stacker cranes are key equipment for improving production efficiency and reducing labor costs. Traditional manual stacking methods are labor-intensive, inefficient, and struggle to guarantee the stability and consistency of stacking.

[0003] Existing automated stacking equipment is prone to misalignment or stacking during carton transport, leading to subsequent clamping and stacking failures. Some existing equipment uses fixed baffles for limiting movement, but these cannot be dynamically adjusted, easily causing carton jamming or feeding difficulties. During carton lifting, traditional equipment often lacks effective anti-interference measures, causing subsequent cartons to mistakenly enter the lifting area, affecting the reset of the feeding plate. Furthermore, the clamping mechanism has a single movement trajectory, making it difficult to accurately grasp cartons of different sizes. Summary of the Invention

[0004] The purpose of this invention is to address the problems in existing technologies where cartons easily shift or accumulate during transport, leading to subsequent clamping and stacking failures. Some existing equipment uses fixed baffles for limiting movement, but these cannot be dynamically adjusted, easily causing cartons to jam or resulting in poor feeding. During the carton lifting process, traditional equipment often lacks effective anti-interference measures, causing subsequent cartons to mistakenly enter the lifting area, affecting the reset of the feeding plate. Furthermore, the clamping mechanism has a single movement trajectory, making it difficult to accurately grasp cartons of different sizes.

[0005] To achieve the above objectives, the present invention employs the following technical solution: an automatic carton stacking machine, comprising: a conveyor belt, a base plate provided on one side of the conveyor belt, a vertical plate fixedly installed on one side of the base plate, two hollow grooves formed on the outer surface of the vertical plate, a feeding plate slidably connected inside the two hollow grooves, the feeding plate being located above the conveyor belt, a cylinder fixedly installed on one side of the vertical plate, the bottom end of the cylinder fixedly installed on the top of the feeding plate, two limiting telescopic rods fixedly installed on one side of the conveyor belt, and lifting bars fixedly installed at the bottom ends of the two limiting telescopic rods.

[0006] The technical effect of adopting the above-mentioned further solution is that the cylinder is started by an external power source. At this time, the cylinder drives the feeding plate to move upward inside the round rod, which can raise the carton and facilitate clamping and conveying.

[0007] In a preferred embodiment, a motor is fixedly installed on the top of the base plate, a rotating rod is fixedly installed on the output end of the motor, a threaded rod is fixedly installed on one end of the rotating rod, two round rods are fixedly installed on the top of the base plate, a crossbar is movably sleeved on the outer surface of the two round rods, the crossbar is slidably sleeved on the outer surface of the threaded rod, a groove is opened at the bottom of the crossbar, an electric push rod is fixedly installed at the bottom of the crossbar, and a slider is fixedly installed at one end of the electric push rod.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: the motor is started by an external power source, and the motor drives the rotating rod to rotate. At this time, the rotating rod drives the threaded rod to rotate. When the threaded rod rotates, it can drive the horizontal bar on its outer surface to slide on the outer surface of the two round rods. When sliding, it drives the moving block at the bottom to move laterally. At this time, the moving block is located on one side of the feeding plate, which can drive the moving block to move vertically, thereby improving the conveying efficiency.

[0009] In a preferred embodiment, the slider slides inside the groove, an electric push rod is fixedly installed at the bottom of the slider, a moving block is fixedly installed at the bottom of the electric push rod, a fixed clamping block is fixedly installed at the bottom of the moving block, two moving clamping blocks are fixedly installed at the bottom of the moving block, a limiting rod is movably sleeved on the outer surface of the two moving clamping blocks, and an electric push rod is fixedly installed at the bottom of the moving block.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: by starting the electric push rod two with an external power source, the moving clamp block slides on the outer surface of the limit rod. After sliding, the moving clamp block and the fixed clamp block can clamp the carton. By starting the electric push rod three with an external power source, the slider moves inside the slide groove. At this time, the carton at the bottom can be clamped and transported to the other side of the conveyor belt for stacking.

[0011] In a preferred embodiment, the electric push rod two is fixedly connected to the outer surface of the limiting rod, the top of the base plate is connected to the threaded rod two via a bearing, the top end of the threaded rod two is fixedly connected to the rotating rod two, and the top end of the rotating rod two is fixedly mounted with a gear.

[0012] The technical effect of adopting the above-mentioned further solution is as follows: when the slider moves laterally, the rack moves laterally through the limiting telescopic bar. At this time, the rack moves on the outer surface of the gear, which can drive the meshing gear to rotate. At this time, the gear rotates and drives the rotating rod two at its bottom to rotate. The rotating rod two drives the threaded rod two to rotate. At this time, the lifting bar connected to the outer surface of the threaded rod two moves up and down under the limitation of the limiting telescopic bar one.

[0013] In a preferred embodiment, a limiting telescopic strip is fixedly installed on one side of the slider, and a rack is fixedly installed on one end of the limiting telescopic strip. The rack is meshed with the outer surface of the gear, and a limiting telescopic rod II is fixedly installed on one end of the rack. The lifting strip is movably sleeved on the outer surface of the threaded rod II through a connecting strip.

[0014] The technical effect of adopting the above-mentioned further solution is as follows: When the carton is conveyed above the conveyor belt, in order to prevent the carton being conveyed from entering the bottom of the feeding plate after the feeding plate is lifted, thus preventing the feeding plate from moving downward, the lifting bar blocks the carton from moving on the upper surface of the conveyor belt. When the moving block moves towards the cylinder, the lifting bar moves upward. When the moving block moves away from the vertical plate, the gear rotates in the opposite direction. At this time, the lifting bar moves downward, which can block the carton. The forward and reverse rotation of the gear can make the threaded rod two rotate simultaneously. At this time, the lifting bar connected to its outer surface by the connecting bar rises or falls under the limit of the limiting telescopic rod one, which can block the carton from moving on the upper surface of the conveyor belt.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. In this embodiment of the invention, the carton is conveyed towards the vertical plate via a conveyor belt, then enters directly below the lifting bar, and then enters the upper surface of the feeding plate. An external power source activates the cylinder, which drives the feeding plate to move upwards inside the round rod, raising the carton for easier clamping. Simultaneously, an external power source activates the motor, which drives rotating rod one to rotate. Rotating rod one then drives threaded rod one to rotate. When threaded rod one rotates, it causes the horizontal bar on its outer surface to slide on the outer surface of the two round rods. During this sliding motion, the moving block at its bottom moves laterally, placing it on one side of the feeding plate. An external power source activates electric push rod three, which drives the slider to slide laterally inside the slide groove. After sliding, the moving block is positioned directly above the feeding plate. Activating electric push rod one pushes the moving block downwards. Activating electric push rod two pushes the moving clamp block to slide on the outer surface of the limiting rod. After sliding, the moving clamp block and the fixed clamp block clamp the carton.

[0017] 2. In this embodiment of the invention, when the carton is being conveyed above the conveyor belt, in order to prevent the carton being conveyed from entering the bottom of the feeding plate after the feeding plate is lifted, thus preventing the feeding plate from moving downward, the lifting bar blocks the carton from moving on the upper surface of the conveyor belt. When the moving block moves towards the cylinder, the lifting bar moves upward. When the moving block moves away from the vertical plate, the gear rotates in the opposite direction. At this time, the lifting bar moves downward to block the carton. The forward and reverse rotation of the gear can make the threaded rod two rotate simultaneously. At this time, the lifting bar connected to its outer surface by the connecting bar rises or falls under the limit of the limiting telescopic rod one, which can block the carton from moving on the upper surface of the conveyor belt.

[0018] 3. In this embodiment of the invention, the electric push rod three is activated by an external power source to push the slider to move inside the chute. At this time, the carton at its bottom can be clamped and transported to the other side of the conveyor belt for stacking. At the same time, when the slider moves laterally, the rack moves laterally through the limiting telescopic strip. At this time, the rack moves on the outer surface of the gear, which can drive the meshing gear to rotate. At this time, the gear rotates and drives the rotating rod two at its bottom to rotate. The rotating rod two drives the threaded rod two to rotate. At this time, the lifting strip connected to the outer surface of the threaded rod two moves up and down under the limitation of the limiting telescopic rod one. When the carton is being transported above the conveyor belt, in order to prevent the carton being transported from entering the bottom of the feeding plate after the feeding plate is lifted, the feeding plate cannot move downward.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 This embodiment provides a technical solution: an automatic cardboard box stacker, comprising: an automatic cardboard box stacker, comprising: a conveyor belt 101, a base plate 102 provided on one side of the conveyor belt 101, a vertical plate 121 fixedly installed on one side of the base plate 102, two hollow grooves 1241 formed on the outer surface of the vertical plate 121, a feeding plate 123 slidably connected inside the two hollow grooves 1241, the feeding plate 123 being located above the conveyor belt 101, a cylinder 122 fixedly installed on one side of the vertical plate 121, the bottom end of the cylinder 122 fixedly installed on the top of the feeding plate 123, two limiting telescopic rods 119 fixedly installed on one side of the conveyor belt 101, and lifting bars 120 fixedly installed at the bottom ends of the two limiting telescopic rods 119.

[0031] When in use, the cylinder 122 is started by an external power source. At this time, the cylinder 122 drives the feeding plate 123 to move upward inside the round rod 124, which can raise the carton for easy clamping and conveying.

[0032] like Figures 1 to 8As shown, in one embodiment, a motor 103 is fixedly installed on the top of the base plate 102. A rotating rod 104 is fixedly installed at the output end of the motor 103. A threaded rod 105 is fixedly installed at one end of the rotating rod 104. Two round rods 124 are fixedly installed on the top of the base plate 102. A crossbar 106 is movably sleeved on the outer surface of the two round rods 124. The crossbar 106 is slidably sleeved on the outer surface of the threaded rod 105. A groove 107 is opened at the bottom of the crossbar 106. An electric push rod 125 is fixedly installed at the bottom of the crossbar 106. A slider 108 is fixedly installed at one end of the electric push rod 125. The motor 103 is started by an external power source. The motor 103 drives the rotating rod 104 to rotate. At this time, the rotating rod 104 drives the threaded rod 105 to rotate. When the threaded rod 105 rotates, it can drive the horizontal bar 106 on its outer surface to slide on the outer surface of the two round rods 124. When sliding, it drives the moving block 111 at its bottom to move laterally. At this time, the moving block 111 is located on one side of the feeding plate 123, which can drive the moving block 111 to move vertically, thereby improving the conveying efficiency.

[0033] like Figures 1 to 8 As shown, in one embodiment, the slider 108 slides inside the chute 107. An electric push rod 110 is fixedly installed at the bottom of the slider 108. A moving block 111 is fixedly installed at the bottom of the electric push rod 110. A fixed clamping block 112 is fixedly installed at the bottom of the moving block 111. Two moving clamping blocks 114 are fixedly installed at the bottom of the moving block 111. A limiting rod 113 is movably sleeved on the outer surface of the two moving clamping blocks 114. An electric push rod 115 is fixedly installed at the bottom of the moving block 111. When the electric push rod 115 is started by an external power source, it pushes the moving clamping block 114 to slide on the outer surface of the limiting rod 113. After sliding, the moving clamping block 114 and the fixed clamping block 112 can clamp the carton. When the electric push rod 125 is started by an external power source, it pushes the slider 108 to move inside the chute 107. At this time, the carton at its bottom can be clamped and transported to the other side of the conveyor belt 101 for stacking.

[0034] like Figures 1 to 8 As shown, in one embodiment, the electric push rod 115 is fixedly connected to the outer surface of the limiting rod 113. The top of the base plate 102 is connected to the threaded rod 118 via a bearing. The top of the threaded rod 118 is fixedly connected to the rotating rod 117. The top of the rotating rod 117 is fixedly mounted with a gear 116. When the slider 108 moves laterally, the rack 1101 moves laterally via the limiting telescopic bar 109. At this time, the rack 1101 moves on the outer surface of the gear 116, which can drive the meshing gear 116 to rotate. At this time, the rotation of the gear 116 drives the rotating rod 117 at its bottom to rotate. The rotating rod 117 drives the threaded rod 118 to rotate. At this time, the lifting bar 120 connected to the outer surface of the threaded rod 118 moves up and down under the limitation of the limiting telescopic bar 119.

[0035] like Figures 1 to 8 As shown, in one embodiment, a limiting telescopic strip 109 is fixedly installed on one side of the slider 108, and a rack 1101 is fixedly installed on one end of the limiting telescopic strip 109. The rack 1101 is meshed with the outer surface of the gear 116, and a limiting telescopic rod 126 is fixedly installed on one end of the rack 1101. The lifting strip 120 is movably sleeved on the outer surface of the threaded rod 118 through a connecting strip. When the carton is conveyed above the conveyor belt 101, in order to prevent the carton being conveyed from entering the bottom of the feeding plate 123 after the feeding plate 123 is lifted, thus preventing the feeding plate 123 from moving downward. At this time, the lifting bar 120 blocks the carton from moving on the upper surface of the conveyor belt 101. When the moving block 111 moves toward the cylinder 122, the lifting bar 120 moves upward. When the moving block 111 moves away from the vertical plate 121, the gear 116 rotates in the opposite direction. At this time, the lifting bar 120 moves downward to block the carton. The forward and reverse rotation of the gear 116 can make the threaded rod 118 rotate simultaneously. At this time, the lifting bar 120, whose outer surface is connected by the connecting bar, rises or falls under the limit of the limiting telescopic rod 119, which can block the carton from moving on the upper surface of the conveyor belt 101.

[0036] Working principle: During use, the carton is conveyed towards the vertical plate 121 via the conveyor belt 101, then enters directly below the lifting bar 120, and then enters the upper surface of the feeding plate 123. The cylinder 122 is activated by an external power source, causing the feeding plate 123 to move upwards inside the round rod 124, raising the carton for easier clamping. Simultaneously, the motor 103 is activated by an external power source, driving the rotating rod 104 to rotate. The rotating rod 104 then drives the threaded rod 105 to rotate. When the threaded rod 105 rotates, it causes the horizontal bar 106 on its outer surface to slide on the outer surface of the two round rods 124, thus sliding the bottom of the threaded rod. The moving block 111 moves laterally, and at this time, the moving block 111 is located on one side of the feeding plate 123. At this time, the electric push rod 125 is activated by the external power supply. The electric push rod 125 drives the slider 108 to slide laterally inside the slide groove 107. After sliding, the moving block 111 is located directly above the feeding plate 123. The moving block 111 is pushed downward by activating the electric push rod 110. At this time, the moving clamp 114 is pushed to slide on the outer surface of the limit rod 113 by activating the electric push rod 115 by the external power supply. After sliding, the moving clamp 114 and the fixed clamp 112 can clamp the carton. The slider 108 is pushed to move inside the slide groove 107 by activating the electric push rod 125 by the external power supply. At this time, the bottom of the carton can be clamped and conveyed to the other side of the conveyor belt 101 for stacking. Simultaneously, as the slider 108 moves laterally, the rack 1101 moves laterally via the limiting telescopic bar 109. The rack 1101 moves on the outer surface of the gear 116, causing the meshing gear 116 to rotate. The rotation of the gear 116 then rotates the rotating rod 117 at its bottom, which in turn rotates the threaded rod 118. The lifting bar 120 connected to the outer surface of the threaded rod 118 moves up and down under the limitation of the limiting telescopic bar 119. When the carton is being conveyed above the conveyor belt 101, to prevent the carton from being conveyed after the feeding plate 123 has been lifted... The cardboard box enters the bottom of the feeding plate 123, causing the feeding plate 123 to be unable to move downward. At this time, the lifting bar 120 blocks the cardboard box from moving on the upper surface of the conveyor belt 101. When the moving block 111 moves towards the cylinder 122, the lifting bar 120 moves upward. When the moving block 111 moves away from the vertical plate 121, the gear 116 rotates in the opposite direction. At this time, the lifting bar 120 moves downward, which can block the cardboard box. The forward and reverse rotation of the gear 116 can make the threaded rod 118 rotate simultaneously. At this time, the lifting bar 120, which is connected to the outer surface by the connecting bar, rises or falls under the limit of the limiting telescopic rod 119, which can block the cardboard box from moving on the upper surface of the conveyor belt 101.
