Description

Technical Field

[0001] This invention relates to the field of carton palletizing technology, and more particularly to a carton palletizing machine. Background Technology

[0002] In modern logistics and automated production processes, cardboard box stacking is a crucial step. Traditional cardboard box stacking typically relies on manual operation, which is not only inefficient but also prone to problems such as tilting and unstable stacking. Therefore, designing an automated, efficient, and stable cardboard box stacking device is of paramount importance.

[0003] Existing cardboard box palletizing technologies mostly employ robotic arms, pneumatic grippers, or electric push rods for the transfer and clamping of cartons. While these methods improve efficiency to some extent, they still have some shortcomings. For example, excessive clamping force during the clamping process may damage the outer surface of the carton, affecting its appearance; while unstable clamping may cause the carton to tilt or fall during stacking. In addition, traditional cardboard box stacking equipment lacks sufficient control over the stability and accuracy of the cartons, especially when handling cartons of different specifications or sizes, making it difficult to achieve precise clamping and stacking. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where excessive clamping force during carton clamping may damage the outer surface of the carton and affect its appearance; while unstable clamping may cause the carton to tilt or fall during stacking. In addition, traditional carton stacking equipment does not have sufficient control over the stability and accuracy of the carton, especially when handling cartons of different specifications or sizes, it is difficult to achieve precise clamping and stacking.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a carton palletizing machine, comprising: a flat plate, a conveyor belt fixedly mounted on the top of the flat plate, a vertical plate fixedly mounted on the top of the flat plate, a rotating rod movably embedded in the inner wall of the vertical plate, a linkage plate movably sleeved on the outer surface of the rotating rod, a top plate fixedly mounted on the top of the linkage plate, a limiting plate fixedly mounted on the top of the flat plate near the top plate, a vertical groove formed inside the limiting plate, a slider slidably connected inside the vertical groove, a lifting plate fixedly mounted on one side of the slider, and the lifting plate sliding on the upper surface of the conveyor belt.

[0006] The technical effect of adopting the above-mentioned further solution is as follows: The L-shaped linkage bar is located on the upper surface of the linkage plate, pushing one end of the linkage plate downward. At this time, under the limit of the first rotating rod, the other end of the linkage plate moves upward, which drives the top plate to move upward. At this time, the top plate contacts the bottom of the slider, pushing the slider to move upward inside the vertical groove. At this time, the slider drives the lifting plate to move upward, and the carton above the lifting plate will be driven to move upward. At this time, the carton is in a stationary state. When the lifting plate lifts the carton, the carton is in a stationary state and will not move, thus avoiding the situation of the carton deviating when being clamped.

[0007] In a preferred embodiment, a support plate is fixedly installed on the top of the flat plate. Two limiting rods are fixedly installed on the side of the support plate near its top. A moving block is slidably connected to the outer surface of the two support plates. A cylinder is fixedly installed on one side of the support plate. A moving block is fixedly installed on one side of the cylinder. One end of the cylinder is fixedly installed on one side of the moving block. Multiple electric push rods are fixedly installed at the bottom of the moving block. A fixing plate is fixedly installed at the bottom of the multiple electric push rods. A motor is fixedly installed at the bottom of the fixing plate.

[0008] The technical effect of adopting the above-mentioned further solution is: by starting the electric push rod with an external power source, the fixed plate is pushed to move downward. At this time, the fixed plate drives the L-shaped linkage bar on one side to move downward. At this time, the L-shaped linkage bar is located on the upper surface of the linkage plate and pushes one end of the linkage plate to move downward.

[0009] In a preferred embodiment, a rotating rod three is fixedly installed at the output end of the motor. A V-shaped clamping plate one is fixedly sleeved on the outer surface of the rotating rod three. A rotating rod two is rotatably connected to the bottom of the fixed plate through a bearing. A gear two is fixedly sleeved on the outer surface of the rotating rod two. The gear two is meshed with the outer surface of the gear one. A V-shaped clamping plate two is fixedly sleeved on the outer surface of the rotating rod two. Two dampers two are fixedly installed on the opposite side of the V-shaped clamping plate two and the V-shaped clamping plate one near their bottoms.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: the motor drives the rotating rod three to rotate, at which time the rotating rod three drives the V-shaped clamping plate one to rotate, the gear one drives the meshing gear two to rotate, at which time the gear two drives the rotating rod two to rotate, the rotating rod two drives the V-shaped clamping plate two to move, at which time the V-shaped clamping plate two moves relative to the V-shaped clamping plate one, at which time the rectangular plate moves relative to the rectangular plate, and the two rectangular plates clamp and fix the carton.

[0011] In a preferred embodiment, two springs are fixedly installed on opposite sides of the V-shaped clamp plate 2 and V-shaped clamp plate 1 near their bottoms. The multiple springs 2 and multiple dampers 2 are evenly divided into two groups. A rectangular plate is fixedly connected to the opposite end of each group of springs 2. An anti-slip pad is fixedly installed on the opposite side of each of the two rectangular plates. An L-shaped linkage bar is fixedly installed on one side of the fixed plate. The L-shaped linkage bar is in contact with the top of the linkage plate.

[0012] The technical effect of adopting the above-mentioned further solution is that the rectangular plate is limited by the cooperation of the spring and the rectangular plate, so that the rectangular plate can move. When the rectangular plate is clamped, it will not clamp the outer surface of the carton too tightly, so as to avoid damage to the outer surface of the carton. The anti-slip pad has an anti-slip function, and the rectangular plate will not slide on the surface of the carton after the carton is clamped, making the clamping more stable.

[0013] In a preferred embodiment, two square plates are fixedly installed on the top of the flat plate, and multiple springs are fixedly installed on opposite sides of the two square plates. Multiple dampers are fixedly installed on opposite sides of the two square plates, and a clamping strip is fixedly connected to one end of each of the multiple springs.

[0014] The technical effect of adopting the above-mentioned further solution is as follows: When the U-shaped push plate contacts the outer surface of the clamping strip, the U-shaped push plate causes the clamping strip to move towards the square plate. When the V-shaped clamping plate one and V-shaped clamping plate two hold the carton on opposite sides of the two clamping strips, the V-shaped clamping plate one and V-shaped clamping plate two move in opposite directions, causing the carton to be located in the middle of the two clamping strips. Under the combined action of spring one and damper one, the clamping strips clamp and fix the carton, making it more stable when stacking.

[0015] In a preferred embodiment, a U-shaped push plate is fixedly installed on one side of the movable block, and the U-shaped push plate is in contact with the outer surface of a plurality of clamping strips.

[0016] The technical effect of adopting the above-mentioned further solution is that the U-shaped push plate moves under the drive of the moving block. At this time, the U-shaped push plate contacts the surface of the clamping strip, thereby pushing the two clamping strips to both sides, and the carton can be put into the interior.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, the rectangular plate is limited by the cooperation of the spring and the rectangular plate, so that the rectangular plate can move. When the rectangular plate is clamped, it will not clamp the outer surface of the carton too tightly, so as to avoid damage to the outer surface of the carton. The anti-slip pad has an anti-slip function, and the rectangular plate will not slide on the surface of the carton after the carton is clamped, so that the clamping is more stable.

[0018] 2. In this embodiment of the invention, the carton is conveyed on the surface of the conveyor belt. When the carton is conveyed to the upper surface of the lifting plate, the electric push rod is activated by an external power source to push the fixed plate downward. At this time, the fixed plate drives the L-shaped linkage bar on one side to move downward. At this time, the L-shaped linkage bar is located on the upper surface of the linkage plate and pushes one end of the linkage plate downward. At this time, under the limit of the rotating rod one, the other end of the linkage plate moves upward, which drives the top plate to move upward. At this time, the top plate contacts the bottom of the slider and pushes the slider to move upward inside the vertical groove. At this time, the slider drives the lifting plate to move upward, and the carton above the lifting plate will be driven to move upward. At this time, the carton is in a stationary state and will not move with the conveyor belt. At this time, after the lifting plate lifts the carton, the V-shaped clamping plate one and the V-shaped clamping plate two are located directly above the carton.

[0019] 3. In this embodiment of the invention, when the lifting plate raises the carton, the carton is stationary and will not move, thus avoiding deviation during clamping. The cylinder is started by an external power source, and the cylinder drives the moving block to move towards the clamping strip on the outer surface of the limiting rod. At this time, the U-shaped push plate contacts the outer surface of the clamping strip, and the U-shaped push plate causes the clamping strip to move towards the square plate. When the V-shaped clamping plate one and V-shaped clamping plate two clamp the carton on opposite sides of the two clamping strips, the V-shaped clamping plate one and V-shaped clamping plate two move in opposite directions, causing the carton to be located in the middle of the two clamping strips. Under the combined action of spring one and damper one, the clamping strip clamps and fixes the carton, making it more stable during stacking. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 8 This embodiment provides a technical solution: a carton palletizing machine, including: a flat plate 101, a conveyor belt 102 fixedly installed on the top of the flat plate 101, a vertical plate 103 fixedly installed on the top of the flat plate 101, a rotating rod 104 movably embedded in the inner wall of the vertical plate 103, a linkage plate 105 movably sleeved on the outer surface of the rotating rod 104, a top plate 110 fixedly installed on the top of the linkage plate 105, a limiting plate 106 fixedly installed on the top of the flat plate 101 near the top plate 110, a vertical groove 107 opened inside the limiting plate 106, a slider 108 slidably connected inside the vertical groove 107, a lifting plate 109 fixedly installed on one side of the slider 108, and the lifting plate 109 sliding on the upper surface of the conveyor belt 102.

[0024] In use, the L-shaped linkage bar 133, located on the upper surface of the linkage plate 105, pushes one end of the linkage plate 105 downward. At this time, under the limit of the rotating rod 104, the other end of the linkage plate 105 moves upward, which drives the top plate 110 to move upward. At this time, the top plate 110 contacts the bottom of the slider 108, which pushes the slider 108 to move upward inside the vertical groove 107. At this time, the slider 108 drives the lifting plate 109 to move upward, and the cardboard box above the lifting plate 109 will be driven to move upward. At this time, the cardboard box is in a stationary state. When the lifting plate 109 raises the cardboard box, the cardboard box is in a stationary state and will not move, thus avoiding the cardboard box from deviating during clamping.

[0025] like Figures 1 to 8 As shown, in one embodiment, a support plate 115 is fixedly installed on the top of the plate 101. Two limiting rods 116 are fixedly installed on the side of the support plate 115 near its top. A moving block 118 is slidably connected to the outer surface of the two support plates 115. A cylinder 117 is fixedly installed on one side of the support plate 115. A moving block 118 is fixedly installed on one side of the cylinder 117. One end of the cylinder 117 is fixedly installed on one side of the moving block 118. Multiple electric push rods 119 are fixedly installed at the bottom of the moving block 118. A fixed plate 120 is fixedly installed at the bottom of the multiple electric push rods 119. A motor 121 is fixedly installed at the bottom of the fixed plate 120. When the electric push rods 119 are started by an external power source, they push the fixed plate 120 downward. At this time, the fixed plate 120 drives the L-shaped linkage bar 133 on one side to move downward. At this time, the L-shaped linkage bar 133 is located on the upper surface of the linkage plate 105 and pushes one end of the linkage plate 105 downward.

[0026] like Figures 1 to 8 As shown, in one embodiment, a rotating rod 126 is fixedly installed at the output end of the motor 121. A V-shaped clamp 123 is fixedly sleeved on the outer surface of the rotating rod 126. A rotating rod 127 is rotatably connected to the bottom of the fixed plate 120 via a bearing. A gear 124 is fixedly sleeved on the outer surface of the rotating rod 127. The gear 124 meshes with the outer surface of the gear 122. A V-shaped clamp 125 is fixedly sleeved on the outer surface of the rotating rod 127. The V-shaped clamp 125 and the V-shaped clamp 123 are located near their bottoms. Two dampers 130 are fixedly installed on opposite sides. Motor 121 drives rotating rod 126 to rotate. At this time, rotating rod 126 drives V-shaped clamp 123 to rotate. Gear 122 drives meshing gear 124 to rotate. At this time, gear 124 drives rotating rod 127 to rotate. Rotating rod 127 drives V-shaped clamp 125 to move. At this time, V-shaped clamp 125 moves relative to V-shaped clamp 123. This causes rectangular plate 128 to move relative to each other. The two rectangular plates 128 clamp and fix the carton.

[0027] like Figures 1 to 8 As shown, in one embodiment, two springs 129 are fixedly installed on opposite sides near the bottom of both V-shaped clamp 125 and V-shaped clamp 123. Multiple springs 129 and multiple dampers 130 are evenly divided into two groups. A rectangular plate 128 is fixedly connected to the opposite end of each group of springs 129. Anti-slip pads 131 are fixedly installed on opposite sides of each rectangular plate 128. An L-shaped linkage bar 133 is fixedly installed on one side of the fixing plate 120. The L-shaped linkage bar 133 contacts the top of the linkage plate 105. The cooperation of the springs 129 and the rectangular plates 128 limits the movement of the rectangular plates 128, allowing them to move. When the rectangular plates 128 clamp, they do not clamp the outer surface of the carton too tightly, thus preventing damage. The anti-slip pads 131 provide anti-slip protection, preventing the rectangular plates 128 from sliding on the surface of the carton after clamping, making the clamping more stable.

[0028] like Figures 1 to 8 As shown, in one embodiment, two square plates 111 are fixedly installed on the top of the flat plate 101. Multiple springs 112 are fixedly installed on opposite sides of the two square plates 111, and multiple dampers 113 are fixedly installed on opposite sides of the two square plates 111. One end of each spring 112 is fixedly connected to a clamping strip 114. A U-shaped push plate 132 contacts the outer surface of the clamping strip 114. At this time, the U-shaped push plate 132 causes the clamping strip 114 to move towards the square plate 111. When the V-shaped clamping plate 123 and the V-shaped clamping plate 125 clamp the carton on opposite sides of the two clamping strips 114, the V-shaped clamping plate 123 and the V-shaped clamping plate 125 move in opposite directions, causing the carton to be located in the middle of the two clamping strips 114. Under the combined action of the springs 112 and the dampers 113, the clamping strip 114 clamps and fixes the carton, making it more stable during stacking.

[0029] like Figures 1 to 8 As shown, in one embodiment, a U-shaped push plate 132 is fixedly installed on one side of the moving block 118. The U-shaped push plate 132 contacts the outer surface of the multiple clamping strips 114. The U-shaped push plate 132 moves under the drive of the moving block 118. At this time, the U-shaped push plate 132 contacts the surface of the clamping strips 114, thereby pushing the two clamping strips 114 to both sides, so that the carton can be put into the interior.

[0030] Working principle: During use, the cardboard box is conveyed on the surface of the conveyor belt 102. When the cardboard box is conveyed to the upper surface of the lifting plate 109, the electric push rod 119 is activated by the external power supply to push the fixed plate 120 downward. At this time, the fixed plate 120 drives the L-shaped linkage bar 133 on one side to move downward. At this time, the L-shaped linkage bar 133 is located on the upper surface of the linkage plate 105, pushing one end of the linkage plate 105 downward. At this time, under the limit of the rotating rod 104, the other end of the linkage plate 105 moves upward, which drives the top plate 110 to move upward. At this time, the top plate 110 contacts the bottom of the slider 108, pushing the slider 108 to move upward inside the vertical groove 107. At this time, the slider 108... When the lifting plate 109 moves upward, the cardboard box above it will be moved upward as well. At this point, the cardboard box remains stationary and will not move with the conveyor belt 102. After the lifting plate 109 lifts the cardboard box, V-shaped clamps 123 and 125 are positioned directly above the cardboard box. The motor 121, powered by an external power source, drives the rotating rod 126 to rotate. The rotating rod 126 then drives the V-shaped clamp 123 to rotate, and gear 122 drives the meshing gear 124 to rotate. Gear 124 then drives the rotating rod 127 to rotate, which in turn moves the V-shaped clamp 125. At this point, the V-shaped clamp 125 is in contact with the V-shaped clamp 123. During the movement, the rectangular plates 128 move relative to each other, clamping and fixing the carton. The spring 129, in conjunction with the rectangular plates 128, limits the movement of the rectangular plates 128, allowing them to move. The rectangular plates 128 do not clamp the outer surface of the carton too tightly, preventing damage. The anti-slip pad 131 also prevents slippage, ensuring a more stable clamping position. When the lifting plate 109 raises the carton, it remains stationary, preventing any deviation during clamping. The cylinder 117 is started by an external power source. The cylinder 117 drives the moving block 118 to move towards the clamping strip 114 on the outer surface of the limit rod 116. At this time, the U-shaped push plate 132 contacts the outer surface of the clamping strip 114. The U-shaped push plate 132 causes the clamping strip 114 to move towards the square plate 111. When the V-shaped clamping plate 123 and the V-shaped clamping plate 125 clamp the carton on opposite sides of the two clamping strips 114, the V-shaped clamping plate 123 and the V-shaped clamping plate 125 move in opposite directions, so that the carton is located in the middle of the two clamping strips 114. Under the cooperation of the spring 112 and the damper 113, the clamping strip 114 clamps and fixes the carton, making it more stable when stacking.
