Description

Technical Field

[0001] The present invention belongs to the field of mechanical structures, and in particular relates to an inclined moving winding device. Background Art

[0002] An aluminum foil slitter is a mechanical device for slitting and trimming aluminum foil materials. Its main function is to slit a wide-width aluminum foil into multiple narrow-width aluminum foils with specific widths and lengths through a cutting process. Generally, it consists of a unwind unit, a main machine, a traction unit, a winding unit, and a waste discharging unit. The semi-finished product running and slitting on the slitter is a process of unwinding and winding, which includes two parts: the running speed control and the tension control of the machine. The so-called tension is to apply a certain tensile and tension force to the aluminum foil in order to traction the aluminum foil and wind it onto the core according to the standard. The tension control force for tensioning the aluminum foil is the tension. Different from a paper slitter, the raw material of paper is thick and not easy to produce wrinkles, while the thickness of aluminum foil is in the micron level. The size of the tension set for the winding and unwinding of the equipment directly affects the yield of the product. If the tension is too large and the winding is too tight, the aluminum foil is prone to wrinkles; if the tension is insufficient, the aluminum foil is prone to serious misalignment of axial slip on the roll, resulting in inability to unroll the roll, and causing large swings of the unwind shaft during slitting, affecting the slitting quality. Therefore, the accuracy requirements for aluminum foil slitters are more stringent.

[0003] In the prior art, the winding method of the slitter is the swing rod type. As the winding diameter continuously increases, the winding pressure needs to be adjusted to meet the constant contact force. The pressure also needs to be adjusted during unrolling, and the pressure control is unstable. Moreover, as the winding diameter increases, the gravity of the winding part continuously increases, and the contact force between the winding part and the rubber roller of the traction part will become larger. A larger contact force will lead to a reduction in the service life of the rubber roller and a poor winding effect. Since the traction unit is installed at the center position of the main machine, the diameter and weight of the rubber roller are large, and it needs to be replaced regularly. The existing replacement method for the rubber roller is to use a crane for hoisting. When hoisting and replacing, other structures affecting the hoisting also need to be disassembled, which is difficult to replace and the process is complex. Summary of the Invention

[0004] In view of this, the present invention aims to provide an inclined moving winding device to solve at least one of the problems in the background art.

[0005] To achieve the above object, the technical solution of the present invention is realized as follows:

[0006] An inclined moving winding device includes a rubber roller and a winding unit. The material is wound by the winding unit after passing through the rubber roller, and includes a sliding unit and a power unit, wherein:

[0007] The winding unit is arranged on the sliding unit, and the winding unit moves relative to the rubber roller along a preset trajectory with the sliding unit;

[0008] The power unit is connected to the sliding unit to drive the sliding unit to move along a preset trajectory;

[0009] Among them, the plane where the preset trajectory is located has an elevation angle relative to the horizontal plane, and the elevation angle value range can be from 0° to 30°.

[0010] Furthermore, the sliding unit includes a mounting plate, a slide rail, and a slider;

[0011] The slide rail is arranged on the side wall, and the mounting plate moves along the slide rail along the preset trajectory through the slider. There is a mounting position for mounting the winding unit on the mounting plate.

[0012] Furthermore, there is a mounting position for mounting a rubber roller on the side wall.

[0013] Furthermore, the mounting position is provided with a locking sleeve.

[0014] Furthermore, a limiting block is arranged on the side of the slide rail to limit the movement stroke of the mounting plate.

[0015] Furthermore, the power unit includes a power source. The power output end of the power source is connected to a connecting seat arranged on the mounting plate to drive the mounting plate to move. Among them:

[0016] The winding unit includes a first state and a second state;

[0017] In response to the first state, at this time the power source executes the first working mode to apply a pulling force to the winding unit;

[0018] In response to the second state, at this time the power source executes the second working mode to apply a pushing force to the winding unit;

[0019] In the above description, the power source includes existing components such as a cylinder or an oil cylinder that can achieve functions such as telescoping / pushing and pulling. The determination criteria for the first state and the second state of the winding unit include:

[0020] Set a threshold value for the contact force between the winding unit and the rubber roller. When the actual contact force is less than the roll diameter threshold value, define the state at this time as the first state, and vice versa as the second state. In response to the first state and the second state respectively, the power source executes the first working mode and the second working mode respectively. When in the first working mode, the power source applies a pulling force to the winding unit, and when in the second working mode, the power source applies a pushing force to the winding unit.

[0021] Furthermore, a synchronization component is arranged below the mounting plate to ensure the synchronous movement of the sliding units arranged on the inner sides of the two side walls.

[0022] Furthermore, the synchronization component includes a rack arranged on the mounting plate. There is a limiting shaft above the rack and a gear shaft below it. The gear shaft is rotatably connected to the side wall;

[0023] The rack is limited by a limiting shaft and a gear shaft;

[0024] The gear shaft serves as a synchronization shaft for associating two sliding units on both sides, and the gear shaft meshes with the rack.

[0025] Furthermore, a rubber roller disassembly tooling is provided on the mounting plate. The rubber roller disassembly tooling has a supporting portion, and a limiting mounting groove is provided on the supporting portion. The limiting mounting groove can be used to mount the screw rod of the limiting bolt;

[0026] When the mounting plate is in a preset position, the supporting portion is located below the shaft head of the rubber roller.

[0027] Furthermore, the winding unit includes a winding shaft, and an included angle exists between the connection line of the axis of the winding shaft and the axis of the rubber roller relative to a preset track.

[0028] Compared with the prior art, the inclined moving winding device of the present invention has the following beneficial effects:

[0029] (1) For the inclined moving winding device of the present invention, through the linear guide rail and the air cylinder, the inclined movement of the winding part is realized. The contact force is controlled by the negative pressure air cylinder and the winding weight, ensuring stable pressure. The gravity of the winding part is borne by the guide rail, avoiding excessive influence of gravity on the contact force;

[0030] (2) For the inclined moving winding device of the present invention, by borrowing the compression and extension of the air cylinder, the rubber roller disassembly tooling is used to realize the rapid disassembly and replacement of the rubber roller;

[0031] (3) For the inclined moving winding device of the present invention, the plane where the slide rail is located has an elevation angle relative to the horizontal plane. The winding unit moves obliquely along the slide rail. At the same time, when the aluminum foil of the winding unit (taking the winding air shaft as an example) is attached to the rubber roller, the attachment point is set above the rubber roller. This setting method can make the gravity of the winding part still act on the rubber roller. As the winding diameter continuously increases, the contact force of the winding gravity acting on the rubber roller increases. The power source will exert an outward thrust to offset the contact force generated by gravity, and at the same time, it can still ensure that part of the gravity continuously acts, keeping the pressure between the wound aluminum foil and the rubber roller within a stable value. Stable pressure can not only protect the rubber roller but also ensure the winding quality;

[0032] (4) For the inclined moving winding device of the present invention, compared with the pendulum type structure adopted by the existing slitter winding, the length of the pendulum arm of the pendulum is constant. As the winding diameter gradually increases, the application point of the contact force between the winding and the rubber roller moves upward accordingly, and the component force of gravity is constantly changing. Then it is necessary to adjust the air cylinder pressure, and the adjustment is relatively difficult. The contact point of this solution remains unchanged as the winding diameter increases. At the same time, the contact force is controlled by the power source to keep the pressure constant and improve the winding quality;

[0033] (5) In the inclined moving and winding device of the present invention, the defect of the existing horizontal moving method is that the contact force (including the pulling force mentioned in this solution) is all provided by the air cylinder. When the coil diameter becomes larger, the self-weight of the winding unit becomes larger. At this time, the air cylinder needs to provide a greater force. In this case, a power source such as an air cylinder with a larger pulling force needs to be selected, resulting in an increase in cost. When the winding unit is in the case of a small coil diameter, whether it is horizontal or inclined, the air cylinder needs to apply a pulling force. When the winding unit is in the case of a large coil diameter, a large pulling force needs to be applied horizontally, and the contact force is provided by the component of gravity in the inclined direction. The component of gravity is greater than the required contact force, and the air cylinder applies a thrust outward. In the whole process, the force required by the horizontal air cylinder is much greater than the force required by the inclined air cylinder, and the requirements for the air cylinder in the horizontal direction are relatively high. In this solution, the plane where the slide rail is located has an elevation angle relative to the horizontal plane, and the winding unit moves along the inclined preset track along the slide rail. The force exerted by the winding unit on the inclined slide rail can be decomposed into gravity and a horizontal component force in the direction of the rubber roller, and a large-sized air cylinder is not required to meet the usage requirements, thus avoiding cost increase.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] This solution discloses an inclined moving winding device. A brief description of the usage scenario is as follows: Wide-width aluminum foil is unwound at the unwinding unit, and after passing through units such as detection and guide rollers, it is slit at the knife groove roller. The slit rolls are wound on the upper and lower air shafts respectively through the traction of the upper and lower rubber rollers according to requirements. The winding device moves inclinedly, and the inclination angle should not be too large. As the winding diameter continuously increases, the contact force of the winding gravity acting on the rubber roller increases. The negative pressure cylinder will apply an external pressure to offset the contact force generated by the gravity, so as to keep the pressure between the winding and the rubber roller within a stable value. Stable pressure can not only protect the rubber roller but also ensure the winding quality.

[0045] Specific improvements are made to two main problems existing in the prior art:

[0046] In the existing technology, as the winding diameter becomes larger, the gravity of the winding part continuously increases, and the contact force between the winding part and the rubber roller will become larger. It is necessary to adjust the pressure immediately to protect the rubber roller and the winding quality; aiming at the problem that the rubber roller is not convenient to disassemble;

[0047] In response to the above problems, this solution is provided with a sliding unit and a power unit. The principle is as follows: The winding unit is arranged on the sliding unit, and the winding unit moves relative to the rubber roller along a preset track with the sliding unit; the power unit is connected to the sliding unit to drive the sliding unit to move along the preset track; the plane where the preset track is located has an elevation angle relative to the horizontal plane;

[0048] The winding unit moves inclinedly along the sliding unit, and the inclination angle (i.e., the elevation angle) should not be too large (generally greater than 0 degrees and less than 30 degrees). At the same time, when the aluminum foil of the winding unit (taking the winding air shaft as an example) is in contact with the rubber roller, the contact point should be above the rubber roller (so that the gravity of the winding part still acts on the rubber roller). As the winding diameter continuously increases, the contact force of the winding gravity acting on the rubber roller increases. The negative pressure cylinder (i.e., the power source) will apply an external pressure to offset the contact force generated by the gravity, and at the same time, it can still ensure that part of the gravity continues to act, so as to keep the pressure between the winding aluminum foil and the rubber roller within a stable value. Stable pressure can not only protect the rubber roller but also ensure the winding quality;

[0049] Among them, in the above description, the power source includes existing components such as cylinders or oil cylinders that can achieve functions such as telescoping / pushing and pulling. The winding unit includes a first state and a second state; in response to the first state, at this time the power source executes the first working mode to apply a pulling force to the winding unit; in response to the second state, at this time the power source executes the second working mode to apply a pushing force to the winding unit;

[0050] The criteria for determining the first state and the second state of the rewinding unit include:

[0051] Set a threshold for the contact force between the rewinding unit and the rubber roller. When the actual contact force is less than the roll diameter threshold, the state at this time is defined as the first state, and vice versa as the second state. In response to the first state and the second state respectively, the power source executes the first working mode and the second working mode. When in the first working mode, the power source applies a pulling force to the rewinding unit. When in the second working mode, the power source applies a pushing force to the rewinding unit;

[0052] In response to the first state and the second state respectively, the power source executes the first working mode and the second working mode. When in the first working mode, the power source is used to apply a pulling force to the rewinding unit. When in the second working mode, the power source is used to apply a pushing force to the rewinding unit support. The purpose of the above operations is to ensure that the relative position and spacing between the rewinding unit and the rubber roller are constant, and thus ensure that the material (such as aluminum foil) is subjected to a constant force. When the rewinding unit moves on the inclined slide rail due to excessive or insufficient self-weight, the power source is used to provide the corresponding pulling force / pushing force to counteract the above movement / movement trend.

[0053] In the attached drawings of this specification, only the structure on one side of the side wall is shown in the device structure, and the structure on the other side is symmetric to it. The side wall 1 is fixed. There is an inclined groove for installing the guide rail on the side wall, and the inclination angle of the groove is the required angle (i.e., the inclination angle, elevation angle). Each winding side is equipped with two slide rails 2. The slide rails 2 are connected to the side wall 1 by bolts. Two sliders 3 are installed on each slide rail 2. The mounting plate 4 is connected to the four sliders 3 by bolts. There is a limit block 6 installed on the side wall 1 on each side of the mounting plate 4. The mounting plate 4 is equipped with a holding sleeve 5, a cylinder connecting seat 13, a rack 8 and a rubber roller disassembly tool 11. The air shaft used for winding is placed on the holding sleeve 5. The cylinder 7 pushes the cylinder connecting seat 13 to make an inclined movement, thereby driving the entire winding device to move parallel in the inclined direction. There is an eccentric shaft 10 (i.e., the limit shaft) above the rack 8. The function of the eccentric shaft 10 is to press the rack to prevent the rack from warping and to level it. There is a gear shaft 9 cooperating with the rack below. The inclined movement of the entire winding device is ensured through the form of gear and rack. The inclined movement of the winding device is realized by the cylinder pushing the slider to slide on the slide rail. The rubber roller disassembly tool 11 is installed on the mounting plate 4. When the winding device moves inward, the rubber roller disassembly tool 11 moves inward accordingly. When the mounting plate 4 moves to contact the inner limit block 6, the rubber roller disassembly tool 11 just moves below the rubber roller 12. There is a threaded hole (i.e., an implementation manner of the limit threaded hole) at the top of the rubber roller disassembly tool 11 where a limit screw can be installed. When it is necessary to take out the rubber roller 12, only the rubber roller holding sleeve 14 needs to be removed, the rubber roller disassembly tool 11 is moved below the rubber roller 12, a screw is installed in the limit screw hole of the rubber roller disassembly tool 11, and then the winding is moved outward. As the winding moves outward, the rubber roller disassembly tool 11 holds the shaft head of the rubber roller 12 and moves the rubber roller 12 out, realizing the quick disassembly of the rubber roller 12 and facilitating replacement.

[0054] Meanwhile, in Figure 5 , a is the guide roller and the cutter groove roller, the vicinity of the b part is the fitting point of the wound aluminum foil and the rubber roller, c is the connection line between the center of the rotation axis of the rubber roller and the center of the rotation axis of the winding unit, e is the winding unit, specifically, it can be expressed as the winding air shaft, d is parallel to the guide rail. The reason for the above settings is as follows: To ensure that the component force of the winding gravity can act on the rubber roller, a parallel line to the guide rail is made with the center of the rubber roller as the base point. It is necessary to ensure that the position of the fitting point of the wound aluminum foil and the rubber roller is above this parallel line. Only above this line can the gravity have a component force pressing on the rubber roller. Specifically, as shown in Figure 5 .
