Description

Technical Field

[0001] The present invention relates to the technical field of calcium carbonate production, and particularly relates to a lifting device for bagged calcium carbonate. Background Art

[0002] After calcium carbonate is produced, for the convenience of subsequent processing, the calcium carbonate needs to be bagged, and then the bagged calcium carbonate is lifted to complete stacking and palletizing.

[0003] Chinese Patent with the publication number CN116553365A discloses a novel nano-calcium carbonate lifting device, including legs, a lifting plate and a bottom box. The top surface of the legs is fixedly installed with a bottom track, and a moving column is slidably connected inside the bottom track. Beneficial effects: The present invention adopts a bottom box, a pressing plate and a vibration motor. When lifting the packaged nano-calcium carbonate, the torque motor drives the main shaft to rotate, and then drives the clamping jaws to pick up the packaged nano-calcium carbonate from the conveyor belt. The torque motor drives the main shaft to rotate in the reverse direction, and the clamping jaws open outward, and the packaged nano-calcium carbonate falls to the stacking position. The electric cylinder extends to push the pressing plate to press the packaging bag of the nano-calcium carbonate, and the vibration motor is started. Through vibration and extrusion, the packaging bag of the nano-calcium carbonate becomes flatter, which is convenient for improving the stability of stacking and palletizing, and avoiding the problem that the packaging bag bulges due to deformation during the clamping process of the nano-calcium carbonate, which affects the later stacking stability, improving the lifting and stacking efficiency, and thus improving the work efficiency. Although the above patent can lift the bagged calcium carbonate to complete stacking and palletizing, the bagged calcium carbonate is only grasped by the clamping jaws on both sides for lifting and moving, and the other two sides of the bagged calcium carbonate are not clamped and limited. The bagged calcium carbonate is easy to shake and fall, resulting in the need to grasp again, affecting the efficiency of lifting and palletizing.

[0004] The present invention aims to solve the problems existing in the above patent. Therefore, a lifting device for bagged calcium carbonate is proposed, which can limit the four sides of the bagged calcium carbonate and then grasp it for lifting and palletizing to prevent the bagged calcium carbonate from falling and affecting lifting, and improve the efficiency of lifting and palletizing. Summary of the Invention

[0005] In order to overcome the disadvantages that although the above patent can lift the bagged calcium carbonate to complete stacking and palletizing, the bagged calcium carbonate is only grasped by the clamping jaws on both sides for lifting and moving, and the other two sides of the bagged calcium carbonate are not clamped and limited. The bagged calcium carbonate is easy to shake and fall, resulting in the need to grasp again, affecting the efficiency of lifting and palletizing, the present invention provides a lifting device for bagged calcium carbonate, which can limit the four sides of the bagged calcium carbonate and then grasp it for lifting and palletizing to prevent the bagged calcium carbonate from falling and affecting lifting, and improve the efficiency of lifting and palletizing.

[0006] The present invention is realized through the following technical solutions: A bagged calcium carbonate lifting device includes a support frame and an electric lifting plate slidably connected between the left and right support frames. An electric movable plate is slidably connected to the inner side of the electric lifting plate. An electric sliding seat is installed on the electric movable plate, and a housing is fixedly connected to the electric sliding seat. A fixed seat is fixedly connected to the housing. Rotating shafts are symmetrically rotatably connected to the fixed seat, and clamping jaws I are fixedly sleeved on the rotating shafts. It also includes a driving component, a leveling component, clamping jaws II, a worm gear II, a worm II, and a guiding bevel gear II. The leveling component is installed on the fixed seat and is used to level the bagged calcium carbonate. Clamping jaws II are symmetrically rotatably connected to the fixed seat. A worm gear II is fixedly sleeved on the shaft portion of the clamping jaws II. The worm II is symmetrically rotatably inserted through the housing and meshes with the worm gear II. A guiding bevel gear II is fixedly sleeved on the worm II. The driving component is installed between the housing and the clamping jaws I. The driving component is used to first drive the clamping jaws I to swing to grab both sides of the bagged calcium carbonate, and then the driving component drives the guiding bevel gear II to rotate. The guiding bevel gear II drives the clamping jaws II to swing through the worm II and the worm gear II, so that the clamping jaws II grab and limit the other two sides of the bagged calcium carbonate.

[0007] Further explanation, the driving component includes a worm gear I fixedly sleeved on the rotating shaft. The worm I is symmetrically rotatably inserted through the housing and meshes with the worm gear I. A guiding bevel gear I is fixedly sleeved on the worm I. A driving motor is installed inside the housing. Two toothless rings are fixedly sleeved on the output shaft of the driving motor. The teeth of the toothless rings are on the left and right sides to drive the guiding bevel gear I and the guiding bevel gear II to rotate.

[0008] Further explanation, the leveling component includes sliding plates symmetrically slidably connected to the bottom of the fixed seat. An elastic telescopic frame is installed at the bottom of the sliding plate. A pressure roller is rotatably connected to the bottom of the elastic telescopic frame to level the bagged calcium carbonate. An electric bidirectional lead screw is installed on the fixed seat, and the electric bidirectional lead screw is threadedly connected to the sliding plate.

[0009] Further explanation, the elastic telescopic frame is composed of a sleeve, a sliding rod, a spring, and a fixed frame. Among them, the sleeves are fixedly connected to the bottom of the sliding plate at equal intervals. The sliding rod is slidably connected to the inside of the sleeve. The spring is connected between the top of the sliding rod and the inner top of the sleeve. The fixed frame is fixedly connected between all the sliding rods.

[0010] Further explanation, the bagged calcium carbonate lifting device also includes a blocking component. The blocking component includes a baffle slidably connected to the clamping jaws I to support and limit the bagged calcium carbonate. A fixing plate is fixedly connected to the clamping jaws I. A driving lead screw threadedly connected to the baffle is rotatably connected between the fixing plate and the clamping jaws I. A servo motor is installed on the clamping jaws I, and the output shaft of the servo motor is connected to the driving lead screw through a bevel gear transmission.

[0011] Further description, the lifting device for bagged calcium carbonate further includes a stabilizing component. The stabilizing component includes air bags fixedly connected to the inner sides of jaw I and jaw II to clamp and fix the bagged calcium carbonate. Single-rod piston cylinders are fixedly connected to the outer side of the housing at circumferentially evenly spaced intervals. An air outlet pipe is connected to the single-rod piston cylinder, and the tail end of the air outlet pipe is connected and communicated with the air bag. A moving component is arranged on the electric slide to drive the piston rod of the single-rod piston cylinder to move.

[0012] Further description, the moving component includes a driving ring vertically slidably connected to the electric slide. The driving ring is fixedly connected to the end of the piston rod of the single-rod piston cylinder to drive the piston rod of the single-rod piston cylinder to move. A cylinder is vertically installed inside the electric slide, and the end of the telescopic rod of the cylinder is fixedly connected to the driving ring.

[0013] Further description, the lifting device for bagged calcium carbonate further includes a protective shell fixedly connected to jaw I. The output shaft of the servo motor is located inside the protective shell, and the protective shell protects the output shaft of the servo motor.

[0014] The beneficial effects of the present invention are as follows: 1. Whenever the elastic telescopic frame contacts the bagged calcium carbonate, start the driving motor, so that the jaws II on the front and rear sides swing downward to clamp and limit the front and rear sides of the bagged calcium carbonate. Subsequently, the jaws I on the left and right sides swing downward to clamp and limit the left and right sides of the bagged calcium carbonate. Then, the electric lifting plate can be started to move upward and reset. Through the electric movable plate and the electric slide, the jaws I and jaws II drive the bagged calcium carbonate to move to the stacking position for palletizing. Since the four sides of the bagged calcium carbonate are clamped and limited, it can prevent the bagged calcium carbonate from falling and affecting lifting, thereby improving the efficiency of lifting and palletizing.

[0015] 2. Under the action of the leveling component, whenever the bagged calcium carbonate is grabbed, lifted and placed for palletizing, the leveling component can level the bagged calcium carbonate, thereby improving the stability of stacking and palletizing the bagged calcium carbonate.

[0016] 3. Under the action of the air bag, whenever the jaws I and jaws II clamp and limit the bagged calcium carbonate, the air bag expands to fill the gaps between the bagged calcium carbonate and the jaws I and jaws II, further clamping and limiting the bagged calcium carbonate. In this way, the bagged calcium carbonate can be further firmly clamped for lifting and palletizing, thereby improving the stability of lifting. Description of the Drawings

[0029] Embodiment: A hoisting device for bagged calcium carbonate, please refer to Figures 1 - 6As shown in the figure, it includes a support frame 1 and an electric lifting plate 2 slidably connected between the left and right support frames 1. An electric movable plate 3 is horizontally slidably connected to the inner side of the electric lifting plate 2. An electric sliding seat 4 is installed on the electric movable plate 3.

Worm gear II 111 is fixedly sleeved in the middle of the shaft parts of the front and back claw II 11. Worm II 112 is rotatably inserted through the front and back of the lower part of the housing 5. The front and back worm II 112 are respectively engaged with the front and back worm gear II 111. Guiding bevel gear II 114 is fixedly sleeved at the positions where the front and back worm II 112 are close to each other. The driving component is installed between the housing 5 and claw I 8. The driving component is used to first drive claw I 8 to swing to grab both sides of the bagged calcium carbonate, and then the driving component drives guiding bevel gear II 114 to rotate. Guiding bevel gear II 114 drives claw II 11 to swing through worm II 112 and worm gear II 111, so that claw II 11 grabs and limits the other two sides of the bagged calcium carbonate.

[0030] Please refer to Figures 2 - 4 As shown in the figure, the driving component includes worm gear I 9, worm I 91, toothless ring 92, driving motor 93 and guiding bevel gear I 94. Worm gear I 9 is fixedly sleeved in the middle of both the left and right rotating shafts 7. Worm I 91 is rotatably inserted through the left and right sides of the lower part of the housing 5. The left and right worm I 91 are respectively engaged with the left and right worm gear I 9. Guiding bevel gear I 94 is fixedly sleeved at the positions where the left and right worm I 91 are close to each other. Driving motor 93 is vertically installed inside the housing 5. Two toothless rings 92 are fixedly sleeved on the output shaft of the driving motor 93. The teeth of the toothless ring 92 are on the left and right sides. When the toothless ring 92 rotates, the toothless ring 92 can drive guiding bevel gear I 94 and guiding bevel gear II 114 to rotate.

[0031] Please refer to Figure 3As shown in the figure, the leveling assembly includes an electric bidirectional lead screw 10, a sliding plate 101, an elastic telescopic frame 102 and a pressure roller 103. The sliding plates 101 are symmetrically and slidably connected to the front and rear of the bottom of the fixed seat 6. The elastic telescopic frames 102 are installed at the bottoms of the sliding plates 101 on both the front and rear sides. The elastic telescopic frame 102 is composed of a sleeve, a sliding rod, a spring and a fixing frame. Among them, the sleeves are fixedly connected to the bottom of the sliding plate 101 at equal intervals. The sliding rod is slidably connected to the inside of the sleeve. The spring is connected between the top of the sliding rod and the inner top of the sleeve. The fixing frame is fixedly connected between all the sliding rods. The pressure rollers 103 are rotatably connected to the bottoms of the elastic telescopic frames 102 on both the front and rear sides. When the pressure roller 103 moves, the pressure roller 103 can level the bagged calcium carbonate. An electric bidirectional lead screw 10 is installed in the middle of the fixed seat 6. The electric bidirectional lead screw 10 is threadedly connected to the upper parts of the sliding plates 101 on both the front and rear sides.

[0032] First, move this device above the bagged calcium carbonate on the conveyor belt, and make the gripper Ⅰ8 and the gripper Ⅱ11 above the bagged calcium carbonate. Then start the driving motor 93 to drive the toothed ring 92 to rotate. The lower toothed ring 92 rotates and meshes with the guiding bevel gear Ⅰ94. The lower toothed ring 92 drives the guiding bevel gear Ⅰ94 to rotate. The guiding bevel gear Ⅰ94 rotates to drive the worm Ⅰ91 to rotate. The worm Ⅰ91 drives the worm gear Ⅰ9 to rotate. The worm gear Ⅰ9 drives the gripper Ⅰ8 to swing upward and open through the rotating shaft 7. Subsequently, the lower toothed ring 92 disengages from the guiding bevel gear Ⅰ94. The self-locking effect of the worm Ⅰ91 and the worm gear Ⅰ9 makes the gripper Ⅰ8 not swing downward. At this time, the upper toothed ring 92 rotates and meshes with the guiding bevel gear Ⅱ114. The upper toothed ring 92 drives the worm Ⅱ112 to rotate through the guiding bevel gear Ⅱ114. The worm Ⅱ112 drives the worm gear Ⅱ111 to rotate. The worm gear Ⅱ111 drives the gripper Ⅱ11 to swing upward and open. When the upper toothed ring 92 disengages from the guiding bevel gear Ⅱ114, turn off the driving motor 93, and the toothed ring 92 stops rotating. Start the electric lifting plate 2 to drive the electric sliding seat 4 to move downward through the electric movable plate 3. The electric sliding seat 4 drives the fixed seat 6 to move downward through the housing 5. The fixed seat 6 drives the gripper Ⅰ8 and the gripper Ⅱ11 to move downward. Moreover, the fixed seat 6 also drives the pressing roller 103 to move downward through the slide plate 101 and the elastic telescopic frame 102. The pressing roller 103 moves downward and contacts the bagged calcium carbonate. Turn off the electric lifting plate 2. Start the electric bidirectional lead screw 10 to rotate forward to drive the slide plates 101 on the front and rear sides to move towards each other. The slide plate 101 drives the pressing rollers 103 on the front and rear sides to move towards each other through the elastic telescopic frame 102. The pressing rollers 103 on the front and rear sides move to level the bagged calcium carbonate, making the bagged calcium carbonate better grasped. Due to the effect of the elastic telescopic frame 102, the pressing roller 103 contacts the bagged calcium carbonate more tightly for leveling treatment. Turn off the electric bidirectional lead screw 10. Then start the driving motor 93 again to drive the toothed ring 92 to rotate. The upper toothed ring 92 drives the guiding bevel gear Ⅱ114 to rotate again, so that the grippers Ⅱ11 on the front and rear sides swing downward to clamp and limit the front and rear sides of the bagged calcium carbonate. Then the lower toothed ring 92 drives the guiding bevel gear Ⅰ94 to rotate again, so that the grippers Ⅰ8 on the left and right sides swing downward to reset and clamp and limit the left and right sides of the bagged calcium carbonate. Turn off the driving motor 93. Then start the electric lifting plate 2 to drive the electric sliding seat 4 to move upward and reset through the electric movable plate 3, which also makes the gripper Ⅰ8 and the gripper Ⅱ11 drive the bagged calcium carbonate to move upward for lifting. Turn off the electric lifting plate 2. Then start the electric movable plate 3 and the electric sliding seat 4 so that the gripper Ⅰ8 and the gripper Ⅱ11 can move left and right and back and forth. The movement of the gripper Ⅰ8 and the gripper Ⅱ11 drives the bagged calcium carbonate to move to the stacking position. Since the four sides of the bagged calcium carbonate are clamped and limited, it is to prevent the bagged calcium carbonate from falling and affecting the lifting, thereby improving the efficiency of lifting and palletizing. Then perform the above operations to make the gripper Ⅰ8 and the gripper Ⅱ11 move downward. The gripper Ⅰ8 and the gripper Ⅱ11 drive the bagged calcium carbonate to move downward for stacking.Then, release the bagged calcium carbonate with gripper I 8 and gripper II 11, and start the reverse rotation of the electric bidirectional lead screw 10 to drive the front and rear slide plates 101 to move and reset in the direction away from each other, which also makes the front and rear pressure rollers 103 move and reset in the direction away from each other. The reset of the pressure rollers 103 levels the bagged calcium carbonate, thereby improving the stacking stability of the bagged calcium carbonate. Repeat this process to continuously lift and stack the bagged calcium carbonate.

[0033] Please refer to Figure 7 As shown, the lifting equipment for bagged calcium carbonate further includes a blocking component installed on the gripper I 8. The blocking component includes a fixing plate 12, a baffle 121, a driving lead screw 122, and a servo motor 123. The lower parts of the left and right grippers I 8 are horizontally and slidably connected with a baffle 121 respectively. When the baffle 121 moves to contact the bottom of the bagged calcium carbonate, the baffle 121 can support and limit the bagged calcium carbonate. Fixing plates 12 are fixedly connected to the lower parts of the left and right grippers I 8 on the sides away from each other. A driving lead screw 122 is rotatably connected between the front side of the fixing plate 12 and the lower part of the gripper I 8. The driving lead screw 122 is threadedly connected to the baffle 121. Servo motors 123 are installed on the sides away from each other of the left and right grippers I 8. The output shaft of the servo motor 123 is connected to the driving lead screw 122 through bevel gears.

[0034] Please refer to Figure 8 and Figure 9 As shown, the lifting equipment for bagged calcium carbonate further includes a stabilizing component installed between the gripper I 8 and the gripper II 11. The stabilizing component includes an airbag 13, a single-rod piston cylinder 131, an air outlet pipe 132, and a moving component. Airbags 13 are fixedly connected to the lower parts of the inner sides of the left and right grippers I 8 and the lower parts of the inner sides of the front and rear grippers II 11. When the airbag 13 expands, the airbag 13 can clamp and fix the bagged calcium carbonate. Four single-rod piston cylinders 131 are fixedly connected to the upper part of the outer side of the housing 5 at equal intervals along the circumferential direction. The bottoms of the four single-rod piston cylinders 131 are all communicated with an air outlet pipe 132. The tails of the four air outlet pipes 132 are respectively connected to and communicated with the four airbags 13. A moving component is arranged on the electric slide 4. When the moving component operates, the moving component can drive the piston rod of the single-rod piston cylinder 131 to move; the moving component includes a driving ring 134 and a cylinder 135. A driving ring 134 is vertically slidably connected to the electric slide 4. The bottom of the driving ring 134 is fixedly connected to the top ends of the piston rods of the four single-rod piston cylinders 131. When the driving ring 134 moves, the driving ring 134 can drive the piston rod of the single-rod piston cylinder 131 to move. A cylinder 135 is vertically installed inside the electric slide 4. The end of the telescopic rod of the cylinder 135 is fixedly connected to the bottom of the driving ring 134.

[0035] When the grippers Ⅰ8 on the left and right sides clamp the left and right sides of the bagged calcium carbonate, start the servo motor 123 to rotate. The servo motor 123 drives the driving lead screw 122 to rotate through bevel gear transmission. The rotation of the driving lead screw 122 drives the baffles 121 on the left and right sides to move towards each other. The baffles 121 on the left and right sides move to contact the bottom of the bagged calcium carbonate. The baffles 121 on the left and right sides support and limit the bagged calcium carbonate. Then turn off the servo motor 123, and the lifting and stacking of the bagged calcium carbonate can begin. When the bagged calcium carbonate moves to the stacking position, start the servo motor 123 to drive the driving lead screw 122 to rotate in the reverse direction through bevel gear transmission. The reverse rotation of the driving lead screw 122 drives the baffles 121 on the left and right sides to move away from each other and reset. The baffle 121 is separated from the bagged calcium carbonate. In this way, the bagged calcium carbonate can be lifted and stacked more stably, and the stability is further improved.

[0036] When the gripper Ⅰ8 and the gripper Ⅱ11 clamp and limit the bagged calcium carbonate, start the cylinder 135. The shortening of the telescopic rod of the cylinder 135 drives the driving ring 134 to move downward. The driving ring 134 drives the piston rod of the single-rod piston cylinder 131 to move downward, so that the air in the single-rod piston cylinder 131 is pushed into the air outlet pipe 132. The air in the air outlet pipe 132 is discharged into the airbag 13. As the air is discharged, the airbag 13 continuously expands and contacts the bagged calcium carbonate. The airbag 13 fills the gap between the bagged calcium carbonate and the gripper Ⅰ8 and the gripper Ⅱ11, and further clamps and limits the bagged calcium carbonate. Then turn off the cylinder 135, and the lifting and stacking of the bagged calcium carbonate can begin. When the bagged calcium carbonate moves to the stacking position, start the cylinder 135 to drive the driving ring 134 to move upward and reset. The driving ring 134 drives the piston rod of the single-rod piston cylinder 131 to move upward and reset, and the air in the airbag 13 is pumped back into the single-rod piston cylinder 131 through the air outlet pipe 132. As the air is pumped away, the airbag 13 continuously contracts and resets and is separated from the bagged calcium carbonate. In this way, the bagged calcium carbonate can be further clamped more stably for lifting and stacking, thereby improving the stability of lifting.

[0037] Please refer to Figure 10 As shown, the lifting device for bagged calcium carbonate further includes a protective housing 14. Protective housings 14 are fixedly connected to the lower parts of the mutually remote sides of the grippers Ⅰ8 on the left and right sides. The output shaft of the servo motor 123 is located inside the protective housing 14, and the protective housing 14 protects the output shaft of the servo motor 123.

[0038] When the servo motor 123 is in use, the protective housing 14 protects the output shaft of the servo motor 123. In this way, foreign objects can be prevented from damaging the output shaft of the servo motor 123, thus ensuring the safety of the use of the servo motor 123.

[0039] Finally, it is necessary to state that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention shall fall within the scope of protection required by the present invention.
