Description

Technical Field

[0001] The present application relates to the technical field of sling transportation, and in particular to a paper roll sling. Background Art

[0002] A paper roll is typically made by wrapping paper around a core tube. During the paper roll production process, it often requires lifting and stacking. During this process, a sling is typically required to lift and transport the paper roll.

[0003] Currently, a typical sling consists of a core shaft with a lifting ring attached to its top and a conical body attached to its lower end. A sleeve is mounted on the outside of the core shaft, matching the inner hole of the core tube inside the paper roll. The lower end of the sleeve is connected to arc-shaped expansion plates via a connecting ring. The arc-shaped expansion plates are symmetrically arranged. During use, the lifting device lifts the core shaft upward. During the upward movement, the expansion plates are pushed outward by the conical body, thus fastening the sling to the paper roll as a whole, allowing both to be lifted simultaneously.

[0004] However, during the lifting process, the volume of the paper roll cannot be judged, which requires operators to control the lifting equipment in real time, thereby reducing production efficiency. Summary of the Invention

[0005] In order to improve the production efficiency of paper rolls, the present application provides a paper roll hanger.

[0006] The present application provides a paper roll sling, which adopts the following technical solution:

[0007] A paper roll hanger includes a hanging plate, a moving component, a detection component, a locking component and a clamping component. The moving component is arranged on the hanging plate, the detection component is arranged on the moving component, and the moving component is used to drive the detection component to measure the diameter of the paper roll; the locking component is arranged on the moving component and is used to stop the moving component from moving; the clamping component is arranged on the hanging plate and is used to clamp the paper roll.

[0008] By adopting the above technical solution, the moving component drives the detection component to measure the diameter of the paper roll. After the measurement is completed, the detection component transmits the measurement signal to the locking component. The locking component responds to the measurement signal and drives the moving component to stop moving. At the same time, the detection component drives the clamping component to clamp the paper roll, so that the device can easily judge the volume of the paper roll by the diameter of the paper roll, and thus it is easy to adjust the clamping force on the paper roll by adjusting the clamping distance between the device and the paper roll, thereby easily improving the production efficiency of the paper roll.

[0009] Optionally, the moving assembly includes a double-headed telescopic rod, a lifting ring and two support rods, the double-headed telescopic rod is fixedly connected to the hanging plate, the piston rod of the double-headed telescopic rod is divided into a first piston rod and a second piston rod in sequence along the direction away from the lifting ring, the first piston rod is slid through the hanging plate, and shares a piston plate with the second piston rod; the lifting ring is located directly above the first piston rod, and the two support rods are respectively located on both sides of the first piston rod, one end of the support rod is slidably connected to the hanging plate, and the other end is hinged to the lifting ring.

[0010] By adopting the above technical solution, when the lifting ring is not pulled by external force, the lifting ring moves toward the hanging plate under the action of its own gravity, and the lifting ring squeezes the first piston rod of the double-headed telescopic rod to move, and the first piston rod of the double-headed telescopic rod pushes the second piston rod to move, and the second piston rod transmits power to the detection component. In the absence of external power, the device can easily automatically detect the diameter of the paper roll, thereby saving energy and reducing production costs.

[0011] Optionally, the detection assembly includes two sliding rods and a bellows, one end of the two sliding rods are hinged to the second piston rod of the double-headed telescopic rod; the two ends of the bellows are respectively fixedly connected to the side of the two sliding rods close to each other; the end of the sliding rod away from the second piston rod is rotatably connected to a pulley; an elastic ring is fixedly sleeved on the end of the sliding rod close to the pulley, and the elastic ring is hollow inside and is made of elastic material.

[0012] By adopting the above technical solution, the first piston rod of the double-headed telescopic rod pushes the second piston rod to move, and the second piston rod drives the slide rod to move to the surface of the paper roll, the pulley abuts against the surface of the paper roll, and the second piston rod applies pressure to the slide rod. Under the action of pressure, the two slide rods move away from each other, and the angle between the two slide rods gradually increases. The pulley rolls on the surface of the paper roll. When the pulley is separated from the surface of the paper roll, the elastic ring abuts tightly against the outer edge of the paper roll, and the paper roll squeezes the elastic ring. The elastic ring transmits power to the locking assembly, thereby facilitating accurate measurement of the diameter of the paper roll, and thus facilitating improving the clamping efficiency of the paper roll.

[0013] Optionally, the locking assembly includes a locking telescopic rod and a fixed plate, the locking telescopic rod is fixedly connected in the chamber where the second piston rod of the double-headed telescopic rod is located, and the movable end is arranged in a direction close to the piston plate, and the two elastic rings are both connected to the rodless cavity of the locking telescopic rod; the fixed plate is fixedly connected to the movable end of the locking telescopic rod.

[0014] By adopting the above technical solution, the paper roll squeezes the elastic ring, and the volume inside the elastic ring decreases. Since the elastic ring is connected to the rodless cavity of the locked telescopic rod, the volume of the rodless cavity of the locked telescopic rod increases, and the movable end of the locked telescopic rod moves, and the movable end of the locked telescopic rod drives the fixed plate to move. The fixed plate presses the piston plate of the double-headed telescopic rod tightly, so that the piston plate of the double-headed telescopic rod stops moving, and the second piston rod of the double-headed telescopic rod stops squeezing the sliding rod, making the sliding rod not easy to move, thereby facilitating accurate measurement of the diameter of the paper roll and thereby improving detection accuracy.

[0015] Optionally, the clamping assembly is provided with multiple groups, and the multiple groups of clamping assemblies are arranged around the hanging plate along the axial direction of the double-headed telescopic rod; the clamping assembly includes a support plate and a fixed telescopic rod, one end of the support plate is fixedly connected to the side of the hanging plate away from the hanging ring; the fixed telescopic rod is fixedly connected to the side of the support plate close to the axis of the double-headed telescopic rod, and the rod cavity of the fixed telescopic rod is connected to the corrugated pipe.

[0016] By adopting the above technical solution, the two sliding rods move in a direction away from each other, the angle between the two sliding rods gradually increases, and the volume inside the bellows increases. Since the rod cavity of the fixed telescopic rod is connected to the bellows, the volume of the rod cavity of the fixed telescopic rod is reduced, the movable end of the fixed telescopic rod moves, and clamps the paper roll, so that it is easy to adjust the clamping force according to different paper roll diameters, and thus it is easy to improve work efficiency.

[0017] Optionally, it further includes multiple groups of reinforcement components, and the multiple groups of reinforcement components correspond one-to-one to the multiple groups of clamping components; the reinforcement component includes a curved plate, a driving part and a reinforcement part, the curved plate is fixedly connected to the movable end of the fixed telescopic rod, and a clearance groove and a locking groove are respectively provided at both ends of the curved plate; the driving part is arranged in the clearance groove, and the reinforcement part is arranged in the locking groove, and the driving part is used to drive the reinforcement part to connect multiple curved plates.

[0018] By adopting the above technical solution, the movable end of the fixed telescopic rod drives the curved plate to move to the paper roll position, and the curved plate clamps the paper roll. During the clamping process, the driving part drives the reinforcement part to move, and the reinforcement part connects multiple curved plates into a whole, thereby easily strengthening the clamping ability of the curved plate on the paper roll, thereby improving the transportation stability of the paper roll.

[0019] Optionally, the driving part includes an elastic pad and an elastic block, the elastic pad is fixedly connected to the side of the curved plate away from the fixed telescopic rod; the elastic block is fixedly connected to the bottom of the give way groove and is connected to the elastic pad, and the elastic pad and the elastic block are both hollow inside.

[0020] By adopting the above technical solution, the curved plate clamps the paper roll, and the curved plate drives the elastic pad to move. The curved plate and the paper roll squeeze the elastic pad at the same time, and the internal volume of the elastic pad decreases. Since the elastic block is connected to the elastic pad, the internal volume of the elastic block increases. Since the elastic block is deformed, the elastic block transmits power to the reinforcement part, so that the reinforcement part can easily connect multiple curved plates into a whole, thereby improving the transportation stability of the paper roll.

[0021] Optionally, the reinforcement part includes a reinforcement curved plate, a locking spring and a locking plate, the reinforcement curved plate is slidably connected in the yield groove and abuts against the elastic block, and the thickness of the reinforcement curved plate is smaller than the width of the positioning groove; two locking grooves are provided in the positioning groove, and the two locking grooves are arranged opposite each other and along the width direction of the positioning groove; one end of the locking spring is fixedly connected to the bottom of the locking groove, and the other end is fixedly connected to the locking plate, and the locking spring is in a stretched state in the initial state; the locking plate is slidably connected in the locking groove, and the distance between the two locking plates is smaller than the thickness of the reinforcement curved plate.

[0022] By adopting the above technical solution, since the elastic block is connected with the elastic pad, the internal volume of the elastic block increases, the elastic block squeezes the reinforcing curved plate to move out of the clearance groove, and drives the reinforcing curved plate to be inserted into the positioning groove, the reinforcing curved plate squeezes the two locking plates, and the reinforcing curved plate is embedded between the two locking plates. The two locking plates clamp the reinforcing curved plate, making it difficult for the reinforcing curved plate to move, thereby improving the stability of the reinforcing curved plate.

[0023] Optionally, a sliding groove is provided on the end of the support plate away from the hanging plate, and an adjustment plate is slidably connected in the sliding groove, and the sliding direction is the axial direction of the support plate; an adjustment spring is fixedly connected between the adjustment plate and the bottom of the sliding groove, and the adjustment spring is in a stretched state in the initial state.

[0024] By adopting the above technical solution, by setting an adjustment plate and an adjustment spring, when the height of the support plate needs to be adjusted, the length of the support plate can be changed by controlling the sliding of the adjustment plate in the slide groove, so that the support plate can be easily kept at a certain distance from the ground, thereby making it easy to keep the distance between the slide rod and the paper roll relatively constant, and thus making it easy to measure the paper roll.

[0025] Optionally, the reinforcing curved plate and the locking plate are both made of ferromagnetic materials.

[0026] By adopting the above technical solution, the stability of the reinforced curved plate is further improved, thereby improving the stability of paper roll transportation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a double-ended telescopic rod, a lifting ring and a supporting rod, the device can automatically detect the diameter of the paper roll, thereby saving energy and reducing production costs;

[0040] The following is combined with Figure 1-6 This application is described in further detail.

[0041] The embodiment of the present application discloses a paper roll hanger. Figure 1 and Figure 2 A paper roll hanger includes a hanging plate 1, a moving component 2, a detection component 3, a locking component 4, a clamping component 5 and a reinforcement component 6. It should be noted that after the paper roll is produced, it is generally placed vertically (it can also be understood that the axis direction of the paper roll is perpendicular to the ground), the moving component 2 is arranged on the hanging plate 1, the detection component 3 is arranged on the moving component 2, and the moving component 2 is used to drive the detection component 3 to measure the diameter of the paper roll; the locking component 4 is arranged on the moving component 2, and is used to stop the moving component 2 from moving; the clamping component 5 is arranged on the hanging plate 1, and is used to clamp the paper roll; the reinforcement component 6 is arranged on the clamping component 5, and is used to further clamp the paper roll.

[0042] When in use, the hanging plate 1 is moved above the paper roll, and the moving component 2 drives the detection component 3 to measure the diameter of the paper roll. After the measurement is completed, the locking component 4 drives the moving component 2 to stop moving. At the same time, the detection component 3 drives the clamping component 5 to clamp the paper roll, so that the device can easily judge the volume of the paper roll by the diameter of the paper roll, and thus it is easy to adjust the clamping distance between the device and the paper roll to adjust the clamping force on the paper roll, thereby easily improving the production efficiency of the paper roll.

[0043] Reference Figure 1 and Figure 2 The hanging plate 1 is circular and horizontally arranged. The moving assembly 2 includes a double-ended telescopic rod 21, a lifting ring 22, and two support rods 23. The double-ended telescopic rod 21 is vertically arranged and fixedly connected to the center of the bottom end of the hanging plate 1. The piston rod of the double-ended telescopic rod 21 is divided into a first piston rod and a second piston rod in the vertical downward direction.

[0044] Reference Figure 2 The first piston rod slides through the hanging plate 1 and shares a piston plate with the second piston rod. A matching plate 211 is fixedly connected to the first piston rod. The matching plate 211 is an arc-shaped plate and is arranged horizontally. The two ends of the matching plate 211 are bent in a direction toward each other, and the distance between the two ends gradually increases in the vertical upward direction.

[0045] Reference Figure 2 The lifting ring 22 is circular and vertically arranged. The lifting ring 22 is located directly above the first piston rod and is adapted to the matching plate 211. Two support rods 23 are located on both sides of the first piston rod. One end of the support rod 23 is hinged to the lifting ring 22, and the other end of the support rod 23 is slidably connected to the hanging plate 1, and the sliding direction is perpendicular to the width direction of the matching plate 211.

[0046] Reference Figure 2 and Figure 3 The detection assembly 3 includes two sliding rods 31 and a bellows 32. One end of each sliding rod 31 is hinged to the end of the second piston rod of the double-ended telescopic rod 21, which is away from the mating plate 211. The sliding rods 31 are rectangular rods. The ends of the bellows 32 are fixedly connected to the sides of the two sliding rods 31 that are close to each other.

[0047] The end of the slide rod 31 away from the second piston rod is rotatably connected to a pulley 311 , and the end of the slide rod 31 close to the pulley 311 is fixedly sleeved with an elastic ring 312 . The elastic ring 312 is hollow inside and made of elastic material.

[0048] Reference Figure 2 and Figure 4 The locking assembly 4 includes a locking telescopic rod 41 and a fixed plate 42. The locking telescopic rod 41 is vertically arranged. The fixed end of the locking telescopic rod 41 is fixedly connected to the chamber where the second piston rod of the double-headed telescopic rod 21 is located, and the movable end is arranged in the direction close to the piston plate.

[0049] Reference Figure 3 and Figure 4 Both elastic rings 312 are connected to the rodless cavity of the locking telescopic rod 41 through a connecting pipe 411, and air flows through the connecting pipe 411. The fixing plate 42 is a rectangular plate and is arranged horizontally. The fixing plate 42 is fixedly connected to one end of the movable end of the locking telescopic rod 41 close to the piston plate of the double-headed telescopic rod 21.

[0050] When in use, the hook lifts the lifting ring 22 and moves the hanging plate 1 above the paper roll. The pulley 311 contacts the upper surface of the paper roll, and the hook is separated from the lifting ring 22. Under the action of its own gravity, the lifting ring 22 moves in the direction close to the hanging plate 1. The lifting ring 22 squeezes the matching plate 211, and the matching plate 211 squeezes the first piston rod of the double-headed telescopic rod 21 to move. The first piston rod pushes the second piston rod to move, and the second piston rod squeezes the end of the sliding rod 31. The sliding rod 31 drives the pulley 311 to move, and the two sliding rods 31 move in the direction away from each other.

[0051] When the pulley 311 is separated from the surface of the paper roll, the elastic ring 312 is in close contact with the outer edge of the paper roll, and the paper roll squeezes the elastic ring 312. The air in the elastic ring 312 enters the rodless cavity of the locking telescopic rod 41 from the connecting tube 411. The air squeezes the movable end of the locking telescopic rod 41 to move. The movable end of the locking telescopic rod 41 drives the fixed plate 42 to move. The fixed plate 42 presses the piston plate of the double-headed telescopic rod 21 tightly, so that the piston plate of the double-headed telescopic rod 21 stops moving.

[0052] The second piston rod of the double-head telescopic rod 21 stops squeezing the slide rod 31, so that the slide rod 31 is not easy to move, thereby facilitating accurate measurement of the diameter of the paper roll and further improving detection accuracy.

[0053] Reference Figure 2 The clamping assembly 5 is provided with multiple groups, and the multiple groups of clamping assemblies 5 are evenly arranged around the central axis of the hanging plate 1. The clamping assembly 5 includes a support plate 51 and a fixed telescopic rod 52. The support plate 51 is a rectangular plate and is vertically arranged. One end of the support plate 51 is fixedly connected to the bottom end of the hanging plate 1.

[0054] Reference Figure 1 and Figure 2 A slide groove 511 is provided on one end of the support plate 51 away from the hanging plate 1, and an adjustment plate 512 is slidably connected to the slide groove 511. The adjustment plate 512 is in the shape of a rectangular plate and is adapted to the slide groove 511. The sliding direction of the adjustment plate 512 is vertical.

[0055] An adjusting spring 513 is fixedly connected between the adjusting plate 512 and the bottom of the sliding groove 511 . The two ends of the adjusting spring 513 are fixedly connected to the bottom of the sliding groove 511 and the adjusting plate 512 respectively. The adjusting spring 513 is in a stretched state in the initial state.

[0056] Reference Figure 2 and Figure 3 The fixed telescopic rod 52 is arranged horizontally, the fixed end of the fixed telescopic rod 52 is fixedly connected to the side of the support plate 51 close to the axis of the double-headed telescopic rod 21, and the movable end is arranged in the direction close to the axis of the double-headed telescopic rod 21. The rod cavity of the fixed telescopic rod 52 is connected to the bellows 32 through a guide tube 521, and air flows through the guide tube 521.

[0057] When in use, the two sliding rods 31 move away from each other, the angle between the two sliding rods 31 gradually increases, the bellows 32 deforms and stretches, and under the action of negative pressure, the air in the rod cavity of the fixed telescopic rod 52 enters the bellows 32 from the guide tube 521, and the movable end of the fixed telescopic rod 52 moves to the side of the paper roll and clamps the paper roll, so that the clamping force can be easily adjusted according to different paper roll diameters, thereby easily improving work efficiency.

[0058] Reference Figure 2 and Figure 5 Multiple reinforcement assemblies 6 are provided, and the multiple reinforcement assemblies 6 correspond one-to-one to the multiple clamping assemblies 5. The reinforcement assembly 6 includes a curved plate 61, a driving portion 62, and a reinforcement portion 63. The curved plate 61 is an arc-shaped plate and is vertically arranged. The two ends of the curved plate 61 are bent toward each other and gradually increase in size as they approach the axis of the double-ended telescopic rod 21.

[0059] Reference Figure 5 and Figure 6The curved plate 61 is fixedly connected to the movable end of the fixed telescopic rod 52 and is adapted to the paper roll. The two ends of the curved plate 61 are respectively provided with a clearance groove 611 and a clamping groove 612, and the clearance groove 611 and the clamping groove 612 are both arc-shaped grooves.

[0060] Reference Figure 5 The driving part 62 includes an elastic pad 621 and an elastic block 622. Both the elastic pad 621 and the elastic block 622 are hollow inside. The elastic pad 621 is fixedly connected to the side of the curved plate 61 away from the fixed telescopic rod 52; the elastic block 622 is fixedly connected to the bottom of the give way groove 611, and is connected to the elastic pad 621 through a drainage pipe 6211, and water flows between the two through the drainage pipe 6211.

[0061] Reference Figure 5 and Figure 6 The reinforcement part 63 includes a reinforcement curved plate 631, a locking spring 632 and a locking plate 633. The reinforcement curved plate 631 is in the shape of an arc plate and is adapted to the clearance groove 611. One end of the reinforcement curved plate 631 is slidably connected in the clearance groove 611 and abuts against the elastic block 622. The thickness of the reinforcement curved plate 631 is less than the width of the locking groove 612. The reinforcement curved plate 631 is made of ferromagnetic material.

[0062] Two locking grooves 6121 are defined within the latching slot 612. The two locking grooves 6121 are disposed opposite each other and extend along the width of the latching slot 612. One end of a locking spring 632 is fixedly connected to the bottom of the locking groove 6121, and the other end is fixedly connected to the locking plate 633. The locking spring 632 is initially in a stretched state.

[0063] The locking plates 633 are rectangular and made of ferromagnetic material. The magnetic force between the two locking plates 633 is less than the elastic force of the locking spring 632. The locking plates 633 slide within the locking grooves 6121, sliding along the width of the retaining grooves 612. The distance between the two locking plates 633 is less than the thickness of the reinforcing curved plate 631 and greater than 0.

[0064] When in use, the movable end of the fixed telescopic rod 52 drives the curved plate 61 to move to the paper roll position, and the curved plate 61 drives the elastic pad 621 to move. The curved plate 61 and the paper roll squeeze the elastic pad 621 at the same time, and the water in the elastic pad 621 enters the elastic block 622 from the drainage tube 6211. The elastic block 622 is deformed and its volume increases. The elastic block 622 squeezes the reinforcing curved plate 631, and the reinforcing curved plate 631 moves out of the yield groove 611 and drives the reinforcing curved plate 631 to be inserted into the locking groove 612 of the adjacent curved plate 61. The reinforcing curved plate 631 squeezes the two locking plates 633, and the reinforcing curved plate 631 is embedded between the two locking plates 633. The two locking plates 633 clamp the reinforcing curved plate 631, so that the reinforcing curved plate 631 is not easy to move, thereby further improving the stability of paper roll transportation.

[0065] The implementation principle of the paper roll hanger of the embodiment of the present application is as follows: under the action of its own weight, the lifting ring 22 squeezes the first piston rod of the double-headed telescopic rod 21 to move, the first piston rod pushes the second piston rod to move, and the second piston rod drives the two sliding rods 31 to drive the pulley 311 to move away from each other;

[0066] When the pulley 311 is separated from the surface of the paper roll, the paper roll presses the elastic ring 312. The air in the elastic ring 312 drives the movable end of the locked telescopic rod 41 through the connecting tube 411, driving the fixed plate 42 to move. The fixed plate 42 presses against the piston plate of the double-headed telescopic rod 21, causing the piston plate of the double-headed telescopic rod 21 to stop moving.

[0067] The two slide rods 31 move away from each other, causing the bellows 32 to deform and stretch. Under the action of negative pressure, the air in the rod cavity of the fixed telescopic rod 52 enters the bellows 32 through the guide tube 521. The movable end of the fixed telescopic rod 52 drives the curved plate 61 to move to the side of the paper roll and clamp the paper roll.

[0068] The curved plate 61 drives the elastic pad 621 to move. The curved plate 61 and the paper roll squeeze the elastic pad 621 at the same time. The water in the elastic pad 621 enters the elastic block 622 from the drainage tube 6211. The elastic block 622 squeezes the reinforcing curved plate 631 to move out of the clearance groove 611 and drives the reinforcing curved plate 631 to be inserted into the clamping groove 612 of the adjacent curved plate 61. The reinforcing curved plate 631 squeezes the two locking plates 633. The reinforcing curved plate 631 is embedded between the two locking plates 633. The two locking plates 633 clamp the reinforcing curved plate 631, making it difficult for the reinforcing curved plate 631 to move, thereby facilitating the adjustment of the clamping force according to different paper roll diameters, thereby improving work efficiency.
