Description

Technical Field

[0001] This invention relates to the field of foil making machine technology, and in particular to a foil making machine flip-type tracking pressure roller mechanism and its usage method. Background Technology

[0002] Electrolytic copper foil is an important material in the manufacture of copper-clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries. A foil-making machine is used for electrolytic copper foil production. In the production process, copper foil is first formed on the surface of the cathode roller, then peeled onto the foil-making machine. After passing through several rollers, it is wound up by a winding mechanism. During winding, as the winding diameter increases, the core of the copper foil is prone to loosening, and the edges are prone to folding. Therefore, the wound copper foil needs to be pressed tightly to achieve perfect winding. The pressure also increases with the winding diameter. The finished copper foil must be free of loosening and wrinkling. The winding mechanism needs to press the wound copper foil tightly in real time during the winding process to prevent loosening and other problems from occurring.

[0003] Chinese utility model patent (application number CN209668407U) discloses an anti-wrinkle pressure roller device, including a bracket and a pressure roller mechanism. One end of the bracket is hinged to a take-up roller via a first bearing, and the other end of the bracket is provided with a pressure roller base. The upper part of the pressure roller base is provided with a contact slope. The height of the contact slope away from the take-up roller is higher than the height of the contact slope near the take-up roller. A roll of copper foil is wound around the take-up roller. The pressure roller mechanism includes a roller core, and a rubber roller is sleeved in the middle of the roller core. A second bearing is provided at each end of the roller core. The second bearings are located on the contact slope. The rubber roller is in contact with the roll of copper foil. By utilizing the weight of the rubber roller itself, combined with the support force provided by the tapered base, the rubber roller can be pressed tightly against the wound copper foil to prevent wrinkles during winding.

[0004] Chinese utility model patent (application number CN217050886U) discloses an electrolytic copper foil winding pressure roller device, which includes a winding roller and a pressure roller. The winding roller is mounted on two supports. Guide rails are also mounted on the two supports. The guide rails are mounted in a radially inclined manner toward the winding roller, and the end of the guide rail closer to the winding roller is lower than the end farther away from the winding roller. The pressure roller is mounted on the two guide rails through pressure roller shafts at both ends, so that the pressure roller forms a structure that presses against the winding roller under its own weight.

[0005] Chinese utility model patent (CN210366179U) discloses a copper foil slitting machine winding pressure roller device, including a slitting machine frame (1) and a winding roller (2). A support roller (3) parallel to and located above the winding roller is also fixed on the slitting machine frame. Support arms (4) extending towards the winding roller are rotatably connected to both ends of the support roller. A pressure roller (5) parallel to the winding roller is connected to the free end of the support arm.

[0006] The pressure rollers in the above patents all use their own weight to press on top of the winding roller. The pressure of the pressure roller on the wound copper foil is constant and cannot be increased as the winding diameter increases. In addition, the weight of the pressure roller is fixed and cannot adapt to the requirements of different copper foil roll diameters. Summary of the Invention

[0007] The problem this invention aims to solve is that existing pressure rollers cannot increase pressure as the diameter of the take-up roller increases, and the weight of the pressure roller cannot be adjusted. To address this, an overturning tracking pressure roller mechanism for a foil production machine and its usage method are provided.

[0008] The technical solution of this invention is: a flip-type tracking pressure roller mechanism for a foil-making machine, comprising: a frame and a take-up roller, further comprising: a fixed shaft, the fixed shaft being rotatably mounted on the frame parallel to the take-up roller; two swing plates, the middle portions of the two swing plates being respectively fixed to both ends of the fixed shaft; a pressure roller, the pressure roller being mounted between one end of the two swing plates; a suspension shaft, the suspension shaft being mounted on the opposite surfaces of the other ends of the two swing plates; a base counterweight, the base counterweight being suspended on the suspension shaft; a bending portion, the bending portion being formed at the free end of the suspension shaft and extending toward the fixed shaft; and a rotating shaft, the rotating shaft being along the fixed shaft. Axial extension of a fixed shaft; two bases, the two bases being fixedly connected to the surface of the fixed shaft and rotatably connected to both ends of a rotating shaft; an upper clamping plate, the middle of which has a through hole that mates with the rotating shaft, and a contact block being fixedly connected to the upper surface of the upper clamping plate; a lower clamping plate, the middle of which is fixedly connected to the bottom of the fixed shaft, and a compression spring being fixedly connected between the upper surface of the lower clamping plate and the lower surface of the upper clamping plate; a connecting member, the connecting member being fixedly connected to the fixed shaft and extending towards the bending portion between the upper and lower clamping plates; and an auxiliary counterweight block, the auxiliary counterweight block being inserted through the connecting member and clamped by the upper and lower clamping plates.

[0009] The bend in the above scheme is an arc-shaped bend.

[0010] An improvement to the above scheme is that the two swing plates are provided with pressure roller adjustment devices on their opposite sides. The pressure roller adjustment devices include bearings that mate with the end faces of the pressure rollers. The bearings are covered with adjustment sliders. The swing plates are provided with openings for the adjustment sliders to slide axially. A fixing block is installed at the opening of the opening, and a bolt is threaded onto the fixing block to be fixed to the adjustment sliders.

[0011] In the above scheme, the two ends of the fixed shaft are mounted on bearing seats via bearings.

[0012] The bolt described in the above scheme includes a nut and a threaded rod, and the nut is a knurled nut.

[0013] The basic counterweight and auxiliary counterweight mentioned in the above scheme are several counterweight rings.

[0014] A method for using a flip-type tracking pressure roller mechanism for a foil production machine includes the following steps: a basic counterweight is suspended on a suspension shaft, an auxiliary counterweight is strung on a connector and held in place by an upper clamping plate and a lower clamping plate, a swing plate drives the pressure roller to press against the surface of the winding roller, and as winding proceeds, the diameter of the copper foil wound on the winding roller increases, making contact with the contact block, causing the upper clamping plate to rotate around the rotation axis, the upper clamping plate to move away from the lower clamping plate, the auxiliary counterweight is released, and it slides down onto the bending part by gravity, thereby automatically increasing the pressure of the pressure roller.

[0015] The advantages of this invention are its simple structure, the lever principle used for controlling the pressing method, which makes the pressure of the device controllable and adjustable, highly accurate, and greatly improves the practicality of the device. The force on the pressure roller remains at the tangential position as the roll diameter increases. The ingenious design allows the auxiliary counterweight to automatically fall onto the suspension shaft as the winding diameter increases, thereby providing more pressure to the pressure roller. The pressure roller adjustment device can finely adjust the position of the pressure roller to ensure levelness and uniform force on the foil surface at all positions of the pressure roller. The number of counterweight rings controls the pressure of the pressure roller. When moving the pressure roller, it can be quickly separated by loading and unloading the counterweight, facilitating the lifting of the roller. Attached Figure Description

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] like Figure 1-4As shown, a foil-making machine's flip-type tracking pressure roller mechanism includes: a frame and a take-up roller 11, and further includes: a fixed shaft 5, which is rotatably mounted on the frame parallel to the take-up roller; two swing plates 3, the middle portions of which are respectively fixed to the two ends of the fixed shaft; a pressure roller 2, which is mounted between one end of the two swing plates; a suspension shaft 21, which is mounted on the opposite surface of the other end of the two swing plates; a base counterweight 4, which is suspended on the suspension shaft, and its function is to provide initial pressure on the take-up roller to the pressure roller and maintain the tilting posture of the swing plates; a bending section 12, which is formed at the free end of the suspension shaft and extends towards the fixed shaft; two rotating shafts 13, which extend axially along the fixed shaft, and there are two rotating shafts, each corresponding to one of the suspension shafts; and two bases 14, which are fixed to the surface of the fixed shaft and rotatably connected to the two ends of the rotating shaft. The two rotating shafts are fitted with four bases, which provide support for the rotating shafts. The upper clamping plate 15 has a through hole in its center that mates with the rotating shaft, allowing it to swing around the shaft. A contact block 16 is fixed to the upper surface of the upper clamping plate. The lower clamping plate 17 is fixed to the bottom of the fixed shaft in its center. A compression spring 18 is fixed between the upper surface of the lower clamping plate and the lower surface of the upper clamping plate. Initially, the compression spring provides an upward thrust to the upper clamping plate, keeping the upper and lower clamping plates close together at their lower ends, ensuring the auxiliary counterweight does not detach from the connector. The connector 19 is fixed to the fixed shaft and extends towards the bend between the upper and lower clamping plates. The connector can be a steel wire rope or other slender piece with a certain degree of rigidity. The auxiliary counterweight 20 passes through the connector and is held by the upper and lower clamping plates.

[0024] A method for using a flip-type tracking pressure roller mechanism for a foil-making machine includes the following steps: a basic counterweight is suspended on a suspension shaft, an auxiliary counterweight is strung on a connector and held in place by an upper clamping plate and a lower clamping plate, a swing plate drives the pressure roller to press against the surface of the take-up roller, as the take-up proceeds, the diameter of the roll wound on the take-up roller increases, and it contacts the contact block, the compression spring is compressed, causing the upper clamping plate to rotate around the rotation axis, the lower part of the upper clamping plate moves away from the lower part of the lower clamping plate, the auxiliary counterweight is released, and it slides down onto the bending part by gravity, thereby automatically increasing the pressure of the pressure roller.

[0025] As a preferred embodiment of the present invention, the auxiliary counterweight block strung on the connector can be a counterweight ring that gradually increases in size from bottom to top. In this way, as the winding diameter increases, the contact block is continuously pressed, the lower part of the upper clamping plate gradually lifts up, and the distance between the upper and lower clamping plates gradually increases, so that the auxiliary counterweight block can be released to the bending part in sequence and guided to the suspension shaft by the bending part to achieve automatic pressurization.

[0026] like Figure 5As shown, in a preferred embodiment of the present invention, a pressure roller adjusting device 1 is provided on the opposite surfaces of the two swing plates. The pressure roller adjusting device includes a bearing 10 that mates with the end face of the pressure roller. Both ends of the fixed shaft are mounted on bearing seats 6 via bearings. An adjusting slider 7 is covered by the bearing. An opening groove is provided on the swing plate for the adjusting slider to slide axially. A fixing block 8 is installed at the opening of the opening groove, and a bolt threaded onto the fixing block is fixed to the adjusting slider. The principle of the pressure adjusting device is to control the position of the adjusting slider in the groove by using a knurled nut, and then tightening the nut to achieve fine adjustment.

[0027] One bearing housing is installed on each side of the winding mechanism frame, and the fixed shaft is mounted on the bearing housing via bearings. The swing plate is mounted on the fixed shaft, with a groove at one end and a counterweight mounting position at the other. The pressure roller adjusting device includes an adjusting slider, a fixed block, a knurled high-strength nut, and bearings. The adjusting slider is installed in the groove at one end of the fixed shaft, and a bearing is installed within the adjusting slider. The fixed block is located at one end of the swing plate, and the knurled high-strength nut is mounted on the fixed block and connected to the adjusting slider via studs. The counterweight is located at one end of the swing plate, and both ends of the pressure roller are mounted on the pressure roller adjusting device.

[0028] As a preferred embodiment of the present invention, the basic counterweight is a plurality of counterweight rings, and the auxiliary counterweight is a plurality of counterweight rings.
