DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1 This embodiment provides a squeezing roller adjustment device, which includes a first mounting frame 1, a second mounting frame 2, a first squeezing roller 3, a second squeezing roller 4, a sliding block 5, and a pressure adjustment device 6. The first mounting frame 1 is used to support the second mounting frame 2 and install the first squeezing roller 3, the second mounting frame 2 is used to install the second squeezing roller 4, a gap is formed between the first squeezing roller 3 and the second squeezing roller 4 and is used to squeeze copper foil, the sliding block 5 is used to connect the first mounting frame 1 and the first squeezing roller 3, and the pressure adjustment device 6 is used to adjust the pressure of the first squeezing roller 3 on the copper foil and the second squeezing roller 4 during operation.

[0020] The second mounting frame 2 is disposed on the first mounting frame 1 , and two oppositely disposed supporting portions 11 extend upward from one side of the first mounting frame 1 .

[0021] The two ends of the first squeeze roller 3 are rotatably connected to the two sliding blocks 5, respectively. Preferably, the two ends of the first squeeze roller 3 can be rotatably connected to the two sliding blocks 5 by bearings. The two sliding blocks 5 are slidably connected to the two supporting parts 11, respectively. Preferably, the sliding blocks 5 and the supporting parts 11 can be slidably connected by linear slide rails, and in order to ensure that the sliding process of the sliding blocks 5 does not affect the rotation of the first squeeze roller 3, the sliding directions of the two sliding blocks 5 must be parallel, that is, the two linear slide rails respectively connected to the two sliding blocks 5 are installed in parallel.

[0022] The two ends of the second extrusion roller 4 are rotatably connected to the second mounting frame 2. Preferably, the two ends of the second extrusion roller 4 are rotatably connected to the second mounting frame 2 via bearings. An extrusion gap is formed between the first extrusion roller 3 and the second extrusion roller 4 for extruding the copper foil.

[0023] The pressure regulating device 6 includes a cylinder 61 and a pressure regulating valve 62. The fixed ends of the two cylinders 61 are fixedly connected to the two supporting parts 11 respectively, and the driving ends of the two cylinders 61 are fixedly connected to the sliding blocks 5 respectively. Therefore, the two cylinders 61 drive the two ends of the first extrusion roller 3 respectively to move the first extrusion roller 3 toward the second extrusion roller 4. The pressure regulating valve 62 is connected to the two cylinders 61 through pipelines. The pressure of the cylinder 61 is changed by adjusting the pressure regulating valve 62 to change the gas pressure in the pipeline, thereby changing the pressure of the first extrusion roller 3 and the second extrusion roller 4 on the copper foil.

[0024] Preferably, the squeezing roller adjustment device also includes a pressure detection device 7, which is arranged between the sliding block 5 and the second mounting frame 2. The pressure detection device 7 includes a guide rod 71, a spring 72, a pressure gauge 73 and a pressure block 74. One end of the guide rod 71 is slidably connected to the sliding block 5, and the other end is fixedly connected to the pressure gauge 73. The spring 72 is sleeved on the guide rod 71, and the two ends are respectively abutted against the sliding block 5 and the pressure gauge 73. The pressure block 74 is fixedly connected to the second mounting frame 2, and the end of the pressure gauge 73 away from the guide rod 71 is abutted against the pressure block 74. The spring 72 drives the pressure gauge 73 to move toward the pressure block 74, thereby ensuring that the pressure gauge 73 and the pressure block 74 are kept in abutment. Preferably, the pressure gauge 73 adopts a digital display type, or the pressure gauge 73 is connected to a digital display screen to display the pressure. Preferably, the abutting surface of the pressure gauge 73 and the pressure block 74 is perpendicular to the axis of the second squeezing roller 4. In this state, the pressure gauge 73 can directly display the pressure acting vertically on the second squeezing roller 4. The following is a brief explanation of the principle of the pressure gauge 73 measuring the extrusion pressure of the first extrusion roller 3 and the second extrusion roller 4 on the copper foil: in the shutdown state, it is necessary to ensure that the pressure gauge 73 is in contact with the pressure block 74, regardless of whether the first extrusion roller 3 and the second extrusion roller 4 are in contact. Because the pressure gauge 73 displays the component of the pressure of the first extrusion roller 3 or the sliding block 5 on the second extrusion roller 4 at right angles to the contact surface between the pressure gauge 73 and the pressure block 74, and when the contact surface between the pressure gauge 73 and the pressure block 74 is perpendicular to the axis of the second extrusion roller 4, the pressure gauge 73 directly displays the pressure on the second extrusion roller 4, and this pressure must be cleared later. In the working state, the first squeezing roller 3 and the second squeezing roller 4 squeeze the copper foil, and the copper foil also squeezes the second squeezing roller 4. At this time, the second squeezing roller 4 is pressed to the right by the copper foil, and the second squeezing roller 4 and the second mounting frame 2 are still kept in a balanced state in the overall horizontal direction. At this time, the pressure of the pressure gauge 73 on the pressure block 74 becomes smaller. This change value is the size of the squeezing force of the copper foil on the second squeezing roller 4, that is, the size of the pressure of the first squeezing roller 3 and the second squeezing roller 4 on the copper foil.

[0025] Preferably, the squeezing roller adjustment device also includes a controller 8, which is electrically connected to the pressure gauge 73 and the pressure regulating valve 62. When the pressure of the first squeezing roller 3 and the second squeezing roller 4 on the copper foil needs to be changed, the pressure regulating valve 62 can be controlled by adjusting the controller 8 to change the pressure of the cylinder 61, and the pressure of the cylinder 61 acts on the sliding block 5 and the first squeezing roller 3, thereby changing the pressure of the first squeezing roller 3 on the copper foil. When the discharge speed needs to be changed, the pressure of the first squeezing roller 3 and the second squeezing roller 4 on the copper foil changes due to the change in the speed of the first squeezing roller 3 and the second squeezing roller 4 on the copper foil, and the reading of the pressure gauge 73 changes accordingly. The signal is transmitted to the controller 8. In order to ensure that the pressure on the copper foil remains unchanged, the program pre-set in the controller 8 can control the pressure regulating valve 62 to change the pressure of the cylinder 61, adjust the pressure of the first squeezing roller 3 on the copper foil, thereby changing the reading of the pressure gauge 73 to a predetermined value, and realizing negative feedback regulation.

[0026] Preferably, the squeezing roller adjustment device also includes a plurality of horizontal adjustment mechanisms 9, which are respectively arranged around the second mounting frame 2, one end of the horizontal adjustment mechanism is fixedly connected to the first mounting frame 1, and the other end is in contact with the side of the second mounting frame 2. Horizontal adjustment mechanisms of different positions and numbers can be set according to the shape of the side of the second mounting frame 2. If the side of the second mounting frame 2 is rectangular, 8 horizontal adjustment mechanisms 9 can be set, 2 on each side, to fix the second mounting frame 2 in the horizontal direction. Further preferably, the horizontal adjustment mechanism 9 includes a mounting block 91 and an adjustment bolt 92, the mounting block 91 is fixedly connected to the first mounting frame 1, the adjustment bolt 92 is threadedly connected to the mounting block 91, and is in contact with the side of the second mounting frame 2, and the position of the second mounting frame 2 can be adjusted by rotating the adjustment bolt 92.

[0027] Preferably, the squeezing roller adjustment device further includes a plurality of vertical adjustment mechanisms 10, which are arranged at the bottom of the second mounting frame 2, the upper end of the vertical adjustment mechanism 10 is fixedly connected to the second mounting frame 2, and the lower end is in contact with the first mounting frame 1. Preferably, the vertical adjustment mechanism 10 is a foot cup, and generally the number of foot cups is at least 4, and the upper and lower positions of the second mounting frame 2 can be adjusted by rotating the nuts on the foot cups. The position of the second mounting frame 2 relative to the first mounting frame 1 can be adjusted by the horizontal adjustment mechanism 9 and the vertical adjustment mechanism 10, and during operation, it must be adjusted until the first squeezing roller 3 and the second squeezing roller 4 are parallel.

[0028] In summary, the utility model provides a liquid squeezing roller adjustment device, which changes the pressure of the two cylinders 61 at the same time by adjusting the pressure regulating valve 62, thereby changing the pressure of the first squeezing roller 3 on the copper foil, which is more efficient, quick and precise than the traditional nut tightening adjustment method. The pressure detection device 7 detects the pressure of the first squeezing roller 3 and the second squeezing roller 4 on the copper foil, realizes pressure visualization, and is more convenient for monitoring. The controller 8 can directly control the pressure regulating valve 62. In addition, when the speed changes, the pre-set program can automatically adjust the pressure regulating valve 62 to keep the pressure detected by the pressure detection device 7 unchanged, avoiding shutdown adjustments and making the production process smoother.

[0029] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
