Description

Technical Field

[0001] This utility model relates to the technical field of roll coating equipment, specifically to an auxiliary coating device for aluminum rolls and a hoisting device. Background Technology

[0002] To protect the surface quality of the outer layers of aluminum and copper coils after winding, a protective layer such as cardboard or plastic film needs to be wrapped around them. After wrapping, the protective layer needs to be secured with transparent tape. When aluminum or copper coils are placed on the ground or countertop, the parts of the coil away from the ground or countertop can be easily wrapped. However, for the parts of the coil in contact with the ground or countertop, due to the contact and weight of the coil, it is not easy to wrap these parts.

[0003] To address the aforementioned issues, existing technologies have incorporated auxiliary packaging devices. For instance, utility model patent CN220518653U discloses a hollow cylindrical auxiliary packaging device and a hoisting machine, comprising a column and a horizontal fixed shaft fixed on the column. A rotating cylinder is coaxially rotatably connected to the fixed shaft, and a crossbeam is fixed on the column. An electric hoist is slidably connected to the crossbeam. When it is necessary to hoist the roll material onto the rotating cylinder, the roll material is driven to rotate relative to the fixed shaft, thus easily completing the film coating operation. After film coating, the electric hoist can be used to easily lift and transfer the roll material.

[0004] While the aforementioned patent facilitates the wrapping and hoisting of roll materials, during prolonged use, the fixed shaft, with one end fixed to the column and the other end suspended, remains suspended due to the weight of the roll material. This not only obstructs the rotation of the rotating drum, affecting the coating efficiency, but also causes the deformed end of the fixed shaft to tilt downwards, posing a significant safety hazard and potentially leading to the roll material falling and being damaged, resulting in wasted costs. Utility Model Content

[0005] The present invention aims to provide an auxiliary coating and hoisting device for aluminum coils, in order to solve the problem in the prior art that the deformation of the fixed shaft affects the coating efficiency of the coil and poses safety hazards during the coating process.

[0006] To solve the above problems, the present invention adopts the following technical solution: an aluminum coil auxiliary coating and hoisting device, including a column and a crossbeam fixedly connected to the column, an electric hoist connected to the crossbeam, a horizontally arranged sliding shaft vertically slidably connected to the column, an elastic support member connected between the column and the sliding shaft, and a rotating cylinder coaxially rotatably connected to the sliding shaft; a middle support part and an end support part cooperating with the sliding shaft are provided below the sliding shaft, and the middle support part and the end support part are respectively located below the two ends of the rotating cylinder.

[0007] The principles and beneficial effects of this application are as follows:

[0008] In this application, when the roll material of the prior art is not installed on the rotating drum, under the elastic support of the elastic support member, the sliding shaft and the rotating drum slide upward to a state away from the intermediate support and the end support. At this time, there is a pick-and-place gap between the fixed shaft and the rotating drum and the end support and the intermediate support. The roll material can be placed on the rotating drum through the pick-and-place gap, or it can be lifted and taken away by the electric hoist from the rotating drum.

[0009] Therefore, in this application, when the roll material needs to be laminated, an electric hoist is used to lift the roll material onto the rotating drum, and then the roll material is gradually released. The weight of the roll material acts on the rotating drum and the sliding shaft. The sliding shaft presses down on the elastic support, causing the elastic support to be compressed. At the same time, the sliding shaft, the rotating drum, and the roll material move downwards. Finally, the sliding shaft stops moving downwards after contacting the intermediate support and the end support. The intermediate support and the end support provide vertical upward support for the sliding shaft. The intermediate support and the end support are located below the two ends of the rotating drum, respectively. Therefore, the end support and the intermediate support can provide support for the positions on the sliding shaft located at the two ends of the rotating drum, preventing the end of the sliding shaft away from the column from being suspended in the air during the roll material lamination process. This avoids the sliding shaft from bending and deforming due to the weight of the roll material during long-term use, effectively ensuring the efficiency of the roll material lamination process and the safety of the lamination process. Once the roll material is coated, simply use an electric hoist to lift the roll material upwards. The sliding shaft and rotating drum will automatically move upwards under the restoring force of the elastic support, so that the sliding shaft moves upwards away from the end support and the middle support, allowing the electric hoist to lift the coated roll material out of the rotating drum.

[0010] Preferably, as an improvement, a rotating shaft is rotatably connected to the end support, and a limit cylinder is coaxially rotatably connected to the rotating shaft; the rotating shaft is provided with a drive mechanism that cooperates with the end of the sliding shaft, and when the sliding shaft slides downward, it contacts the drive mechanism, and the rotating shaft rotates from a horizontal state to a vertical state.

[0011] In this solution, when the sliding shaft drives the rotating drum and the roll material on the rotating drum to move downwards to contact the end support and the intermediate support, the rotating shaft rotates from a horizontal state to a vertical state under the action of the driving mechanism. The limiting cylinder on the rotating shaft also rotates to a vertical state. Since the rotating shaft is rotatably connected to the end support, the limiting cylinder, which rotates to a vertical state, can limit the end of the roll material. Moreover, the limiting cylinder can rotate with the roll material when it rotates, preventing axial movement of the roll material during the film coating process and avoiding friction damage between the end of the roll material and the end support, thus effectively ensuring the quality of the roll material.

[0012] Preferably, as an improvement, the end support includes an end support rod and an end support seat fixedly connected to the top of the end support rod.

[0013] In this design, an end support seat is provided at the top of the end support rod, which facilitates the end support seat to provide stable vertical support for the sliding shaft, and also facilitates the installation of the drive mechanism on the end support seat.

[0014] Preferably, as an improvement, the driving mechanism includes a rotating shaft, a connecting seat, and an elastic reset member, wherein the elastic reset member is fixedly connected between the rotating shaft and the end support seat; the connecting seat is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected to the end support seat, the rotating shaft is fixedly connected to the connecting position of the connecting seat and the rotating shaft, and the end support seat is provided with a rotating groove that rotatably engages with the connecting seat.

[0015] In this solution, when the sliding shaft moves downward to contact the end support, the end of the sliding shaft contacts and abuts against the overlapping seat. The overlapping seat, together with the rotating shaft, rotates relative to the end support, causing the rotating shaft and the limiting cylinder to rotate from a horizontal state to a vertical state, thereby limiting and protecting the roll material. When the sliding shaft moves upward, the rotating shaft and the limiting cylinder automatically rotate to a horizontal state under the elastic force of the elastic reset component, preventing the rotating shaft and the limiting cylinder from obstructing the loading and unloading operation of the roll material on the rotating cylinder. The entire process is completed automatically without manual control.

[0016] Preferably, as an improvement, the end support is provided with a horizontal mating surface and a vertical mating surface. When the rotating shaft rotates to a horizontal state, the rotating shaft contacts the horizontal mating surface; when the rotating shaft rotates to a vertical state, the lap joint contacts the vertical mating surface.

[0017] In this solution, the horizontal mating surface provides support for the rotating shaft to rotate to a horizontal state, facilitating precise resetting of the rotating shaft; the vertical mating surface provides limiting support for the overlapping seat, enabling the limiting cylinder to precisely engage with the end of the roll material for more accurate limiting and better protection.

[0018] Preferably, as an improvement, the rotating shaft and the mounting base are integrally formed.

[0019] Preferably, as an improvement, the intermediate support includes an intermediate support rod and an intermediate support seat fixedly connected to the top of the intermediate support rod, and the intermediate support seat and the end of the rotating cylinder are provided with a clearance gap in the horizontal direction.

[0020] In this solution, an intermediate support seat is set at the top of the intermediate support rod so that the intermediate support seat can provide good support for the sliding shaft. In addition, a clearance gap is provided between the intermediate support seat and the end of the rotating drum in the horizontal direction. When the roll material in the prior art is installed on the rotating drum, the existence of the clearance gap can prevent the roll material from colliding with the intermediate support seat when it is lowered, and prevent damage to the roll material during the film coating process.

[0021] Preferably, as an improvement, the top surface of the end support is provided with an end arc-shaped support surface that cooperates with the sliding shaft, and the top surface of the intermediate support is provided with an intermediate arc-shaped support surface that cooperates with the sliding shaft.

[0022] In this design, by setting an arc-shaped support surface to cooperate with the sliding shaft, the sliding shaft can be supported more stably, and the rotating cylinder can be rotated more stably.

[0023] Preferably, as an improvement, a slide block is slidably connected to the column, and a sliding shaft is fixedly connected to the slide block; a limiting collar located below the slide block is fixedly connected to the column, and the elastic support includes a support spring connected between the limiting collar and the slide block.

[0024] In this design, the slide block and the column slide together. The limiting collar below the slide block helps to limit the downward sliding of the slide block, and the support spring can be easily installed between the limiting collar and the slide block. The installation is convenient and the structure is stable.

[0025] Preferably, as an improvement, the top surface of the limiting collar has a countersunk hole for mounting, the top end of the support spring is fixedly connected to the slide, and the bottom end is located in the countersunk hole for mounting.

[0026] In this design, a countersunk hole is provided on the top surface of the limiting collar, which allows for convenient and stable installation of the support spring. The support spring can also provide more stable support for the slide block, thereby making the vertical sliding of the sliding shaft and the rotating cylinder more stable.

[0031] The following detailed description illustrates the specific implementation method:

[0032] The reference numerals in the accompanying drawings of the instruction manual include: column 1, crossbeam 2, auxiliary support column 3, guide rail 4, electric hoist 5, sliding shaft 6, rotating cylinder 7, slide block 8, limiting collar 9, support spring 10, end support rod 11, end support seat 12, intermediate support rod 13, intermediate support seat 14, rotating shaft 15, limiting cylinder 16, rotating shaft 17, tension spring 18.

[0033] Example 1

[0034] This embodiment is as shown in the attached figure. Figure 1 As shown: An aluminum coil auxiliary coating and hoisting device includes a vertically arranged column 1. The bottom of the column 1 is fixed to the ground by anchor bolts. The top surface of the column 1 is fixedly connected to a crossbeam 2 by welding. To improve the stability of the crossbeam 2 connection, in this embodiment, a vertically arranged auxiliary support column 3 is welded to the end of the crossbeam 2 away from the column 1. The bottom surface of the crossbeam 2 is fixedly connected to a T-shaped guide rail 4 by screws. An electric hoist 5 is slidably connected to the guide rail 4 along the length of the crossbeam 2. Since the structure of the electric hoist 5 sliding laterally on the crossbeam 2 is a conventional technology in this field, the sliding method of the electric hoist 5 and the detailed internal structure of the electric hoist 5 will not be described here.

[0035] like Figure 1 As shown, a horizontally arranged sliding shaft 6 is vertically slidably connected to the column 1. An elastic support is connected between the column 1 and the sliding shaft 6. A rotating cylinder 7 is rotatably connected to the sliding shaft 6 via a bearing. Multiple clearance grooves are formed on the outer wall of the rotating cylinder 7 along the axial direction of the rotating cylinder 7. Figure 2 (Not shown in the image) The existing lifting ropes used for hoisting rolls are avoided by using a relief groove. To prevent wear on the rolls during hoisting, a central paper tube can be set in the middle of the roll. To make the sliding shaft 6 slide more smoothly and steadily, a slide block 8 is vertically slidably connected to the column 1 in this embodiment. The sliding shaft 6 is fixedly connected to the side wall of the slide block 8 by screws or welding. At the same time, a limiting collar 9 is fixedly connected to the column 1 by screws or welding. The limiting collar 9 is located below the slide block 8. The top surface of the limiting collar 9 has a circumferentially arranged mounting countersunk hole. The elastic support includes a support spring 10 connected between the limiting collar 9 and the slide block 8. The support spring 10 is sleeved on the column 1. The bottom end of the support spring 10 contacts the bottom wall of the mounting countersunk hole, and the top end of the support spring 10 abuts against the bottom surface of the slide block 8.

[0036] In this embodiment, an intermediate support and an end support are provided below the sliding shaft 6 to cooperate with the sliding shaft 6. The intermediate support and the end support are located below both ends of the rotating cylinder 7, respectively. Specifically, the end support includes an end support rod 11 and an end support seat 12 fixedly connected to the top of the end support rod 11 by screws, welding, or integral molding. The intermediate support includes an intermediate support rod 13 and an intermediate support seat 14 fixedly connected to the top of the intermediate support rod 13 by screws, welding, or integral molding. The bottom ends of the end support rod 11 and the intermediate support rod 13 are both fixedly connected to the ground by anchor bolts. The top surface of the end support seat 12 has an end arc-shaped support surface that cooperates with the sliding shaft 6, and the top surface of the intermediate support seat 14 has an intermediate arc-shaped support surface that cooperates with the sliding shaft 6. When the sliding shaft 6 slides down to contact the end arc-shaped support surface and the intermediate arc-shaped support surface, the rotating cylinder 7 is located between the end support seat 12 and the intermediate support seat 14, so that the end support seat 12 and the intermediate support seat 14 can provide stable vertical support for the sliding shaft 6.

[0037] The specific implementation process is as follows:

[0038] When the roll material is not being coated, under the elastic force of the support spring 10, the sliding shaft 6 and the rotating cylinder 7 slide upward to the upper limit position. At this time, there is a gap between the sliding shaft 6 and the rotating cylinder 7 and the lower end support seat 12 and the middle support seat 14. At this time, the roll material to be coated in the prior art can be lifted by the electric hoist 5. When lifting, the lifting rope can be passed through the center hole of the roll material and fixed to the electric hoist 5. Then, the roll material is lifted vertically or horizontally by the electric hoist 5, so that the roll material is lifted onto the rotating cylinder 7, and the lifting rope is located in a relief groove on the rotating cylinder 7. Then, the roll material is gradually lowered. The weight of the roll material acts on the rotating cylinder 7, the sliding shaft 6 and the slide seat 8, so that the support spring 10 is compressed and stores force. When the sliding shaft 6 moves down to contact the end arc support surface and the middle arc support surface, it stops moving down. The roll material can be stably supported vertically. At this time, the lifting rope can be removed to realize the installation of the roll material.

[0039] After the roll material is installed, under the action of gravity, the central paper tube inside the roll material is tightly attached to the outer wall of the rotating drum 7. At this time, the film coating operation of the roll material can be easily completed by manually or by using a power component to drive the rotating drum 7 to rotate. In particular, when using a power component to drive the rotating drum 7 to rotate, a motor and gear transmission method can be used to drive the rotating drum 7 to rotate. In use, the motor is fixed on the sliding shaft 6, and the transmission gear is connected between the output shaft of the motor and the rotating drum 7. The motor can automatically drive the rotating drum 7 to rotate, avoiding manual pushing of the roll material to rotate and reducing the labor intensity. Since setting up a motor and gear structure to drive the rotating drum 7 to rotate is a conventional technology in this field, its specific structure will not be described in detail here.

[0040] After the roll material is coated, the lifting rope is passed through the clearance groove and reconnected to the roll material. Then, the electric hoist 5 is used to lift the roll material upward. The sliding shaft 6, rotating cylinder 7, and sliding seat 8 automatically slide upward and reset under the elastic force of the support spring 10. When the sliding shaft 6 moves upward to the upper limit position, the electric hoist 5 is used to move the roll material laterally, so that the roll material exits the rotating cylinder 7 along the axis of the rotating cylinder 7. Finally, the coated roll material is hoisted to the predetermined position. In this embodiment, during the rotation and coating process of the roll material, the two ends of the sliding shaft 6 are supported by the end support seat 12 and the middle support seat 14, respectively, so that the sliding shaft 6 is subjected to uniform force and will not bend due to the weight of the roll material under long-term use, effectively ensuring the coating efficiency and coating quality of the roll material.

[0041] Example 2

[0042] The difference between Example 2 and Example 1 is that: [The text abruptly ends here, likely due to an incomplete sentence or a formatting error.] Figure 2 and Figure 3 As shown, in this embodiment, a rotating shaft 15 is rotatably connected to the top of the end support 12. A limiting cylinder 16 is rotatably connected to the rotating shaft 15 via a bearing. At the same time, a driving mechanism that cooperates with the end of the sliding shaft 6 is provided on the rotating shaft 15. When the sliding shaft 6 slides from top to bottom and contacts the driving mechanism, the rotating shaft 15 can rotate from a horizontal state to a vertical state. After the rotating shaft 15 rotates to a vertical state, the outer wall of the limiting cylinder 16 contacts the end of the roll material. The limiting cylinder 16 can play an axial limiting role for the roll material, preventing axial movement when the roll material is rotated for lamination, and improving the quality of the roll material lamination.

[0043] The driving mechanism in this embodiment includes a rotating shaft 17, a connecting seat, and an elastic reset member. The rotating shaft 17 is rotatably connected to the top of the end support seat 12 via a bearing. The connecting seat is fixedly connected to the rotating shaft 15. In this embodiment, the connecting seat and the rotating shaft 15 are integrally formed. The rotating shaft 17 is fixedly connected to the integral connection position of the connecting seat and the rotating shaft 15 via a flat key. The end support seat 12 is provided with a rotating groove that rotatably engages with the connecting seat. The elastic reset member includes a tension spring 18 that is fixedly connected between the rotating shaft 15 and the end support seat 12 via a hook connection. The end support seat 12 is provided with a horizontal mating surface and a vertical mating surface. When the rotating shaft 15 rotates to a horizontal state, the rotating shaft 15 contacts the horizontal mating surface. When the rotating shaft 15 rotates to a vertical state, the connecting seat contacts the vertical mating surface.

[0044] In this embodiment, when the rotating drum 7 is not in contact with the roll material but is subjected to force, the rotating drum 7 and the sliding shaft 6 are at their upper limit positions. At this time, the rotating shaft 15 and the limiting cylinder 16 are in a horizontal state under the action of the tension spring 18, and the limiting cylinder 16 and the end support 12 have a gap in the vertical direction. Figure 4 As shown, the roll material can be inserted laterally into the rotating drum 7. When the weight of the roll material acts on the rotating drum 7 and the sliding shaft 6, the roll material and the sliding shaft 6 move downwards. The end of the sliding shaft 6 presses against the rotating shaft 15, causing the rotating shaft 15 and the limiting cylinder 16 to finally rotate to a vertical state. The limiting cylinder 16 can play a lateral limiting role for the roll material, thereby preventing lateral movement of the roll material during the coating process, making the roll material coating process more stable, and also protecting the ends of the roll material.
