Description

Technical Field

[0001] This utility model relates to the field of diaphragm processing technology, specifically to a pressure roller gap adjustment structure used in diaphragm production and processing. Background Technology

[0002] During battery film processing, electrode powder is fed into pressure rollers via a powder spreader for pre-pressing the film. After the pre-pressed films are joined together, they are laminated with copper or aluminum foil. The gap between the pressure rollers is adjusted according to the required film thickness. A servo motor drives a high-precision ball screw and wedge block to adjust the gap, ensuring accurate adjustment. The required gap can be automatically adjusted simply by inputting it into the touchscreen.

[0003] The traditional method of adjusting the gap using ball screws and wedges suffers from uneven force distribution during roller gap adjustment over time due to wear on the ball screw, increased nut clearance, and wear on the wedge surface. Furthermore, the varying degrees of wear on different components can cause wedges to shift position during movement, further affecting the uniformity of the roller gap. Therefore, a roller gap adjustment structure based on those used in diaphragm manufacturing is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a pressure roller gap adjustment structure used in diaphragm production and processing, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this invention is achieved through the following technical solution:

[0005] This utility model is based on a pressure roller gap adjustment structure used in diaphragm production and processing, including:

[0006] The adjustment assembly includes a fixed frame, a servo motor, a lead screw, an intermediate wedge, a first wedge, and a second wedge. The servo motor is fixed to one end of the fixed frame, the lead screw is fixed to the output end of the servo motor and rotatably connected to the inside of the fixed frame, the intermediate wedge is fixed to the middle of the inside of the fixed frame, and the lead screw passes through the intermediate wedge. The first wedge and the second wedge are screwed to both ends of the lead screw.

[0007] The limiting component includes a limiting block, a first mounting plate, a first support plate, a second mounting plate, and a ball bearing. The first mounting plate is welded to the lower end of the limiting block and fixed to the middle of the top of the intermediate wedge block by screws. The second mounting plate is welded between the two first support plates and fixed to the top of the first and second wedge blocks near the middle wedge block by screws. The ball bearing is rotatably connected to the side of the intermediate wedge block.

[0008] Furthermore, the limiting component also includes a reinforcing plate, which is fixed to the lower end of the first support plate.

[0009] Furthermore, the adjustment assembly also includes a first limiting rod, the two ends of which are fixed to the fixing frame and pass through the intermediate wedge, the first wedge, and the second wedge.

[0010] Furthermore, the first wedge and the second wedge are located on both sides of the middle wedge, and are equidistant from the middle wedge.

[0011] Furthermore, the first wedge and the second wedge move relative to or away from the middle wedge.

[0012] Furthermore, it also includes an adjustment assembly, which includes a threaded hole, an adjusting rod, and a second support plate. The threaded hole is opened at one end of the first support plate near the middle wedge, the adjusting rod is screwed into the threaded hole, the second support plate is rotatably connected to one end of the adjusting rod, and a ball bearing is rotatably connected to the second support plate.

[0013] Furthermore, the adjustment assembly also includes a limiting hole and a second limiting rod. The limiting hole is opened at one end of the first support plate near the middle wedge and is located on both sides of the threaded hole. One end of the second limiting rod is fixed to the side of the second support plate, and the other end is inserted into the limiting hole.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through the setting of a limiting component, when the servo motor drives the lead screw to rotate, thereby causing the first wedge and the second wedge to move closer to or further away from the middle wedge, causes the ball bearings on the first support plate to roll in contact with the limiting block, so that the first wedge, the second wedge and the middle wedge are kept on the same horizontal line. This setting can avoid the situation where the first wedge, the second wedge and the middle wedge shift their positions after moving due to different wear levels, and maintain the horizontal consistency of each wedge.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-5 As shown, this utility model is a pressure roller gap adjustment structure used in diaphragm production and processing, comprising:

[0028] The adjustment assembly includes a fixed frame 10, a servo motor 11, a lead screw 12, an intermediate wedge 14, a first wedge 15, and a second wedge 16. The servo motor 11 is fixed to one end of the fixed frame 10, the lead screw 12 is fixed to the output end of the servo motor 11 and is rotatably connected to the inside of the fixed frame 10, the intermediate wedge 14 is fixed to the middle of the inside of the fixed frame 10, and the lead screw 12 passes through the intermediate wedge 14. The first wedge 15 and the second wedge 16 are screwed to both ends of the lead screw 12.

[0029] The adjustment assembly also includes a first limiting rod 13, which is fixed at both ends to the fixing frame 10 and passes through the intermediate wedge 14, the first wedge 15 and the second wedge 16;

[0030] The first wedge 15 and the second wedge 16 are located on both sides of the middle wedge 14, and are equidistant from the middle wedge 14.

[0031] The first wedge block 15 and the second wedge block 16 move relative to or away from the middle wedge block 14;

[0032] The fixed frame 10 provides support, the servo motor 11 provides power, the screw 12 rotates to drive the first wedge 15 and the second wedge 16 to move, the first limit rod 13 provides a limit to prevent the first wedge 15 and the second wedge 16 from shaking when they move, the middle wedge 14, the first wedge 15 and the second wedge 16 all provide support, and the side is equipped with a pressure roller driven by a motor to pre-press the powder conveyed by the powder spreader into a film.

[0033] The limiting assembly includes a limiting block 20, a first mounting plate 21, a first support plate 22, a second mounting plate 24, and a ball bearing 25. The first mounting plate 21 is welded to the lower end of the limiting block 20 and fixed to the middle of the top of the intermediate wedge 14 by screws. The second mounting plate 24 is welded between the two first support plates 22 and fixed to the top of the first wedge 15 and the second wedge 16 near the middle wedge 14 by screws. The ball bearing 25 is tactilely connected to the side of the intermediate wedge 14.

[0034] The limiting component also includes a reinforcing plate 23, which is fixed to the lower end of the first support plate 22;

[0035] The limiting block 20 serves as a limiting element, the first mounting plate 21 is used to fix the limiting block 20, the first support plate 22 serves as a support element, the reinforcing plate 23 serves as a reinforcing element, the second mounting plate 24 is used to fix the first support plate 22, and the ball bearing 25 can reduce the frictional resistance between the first support plate 22 and the limiting block 20 when the first support plate 22 moves.

[0036] Working principle:

[0037] The limiting block 20 is fixed to the middle wedge block 14 by the first mounting plate 21, and the first support plate 22 is fixed to the first wedge block 15 and the second wedge block 16 by the second mounting plate 24 respectively. When the servo motor 11 drives the lead screw 12 to rotate, and thus drives the first wedge block 15 and the second wedge block 16 to move closer to or away from the middle wedge block 14, the ball bearings 25 on the first support plate 22 are driven to roll against the limiting block 20, so that the first wedge block 15, the second wedge block 16 and the middle wedge block 14 are kept on the same horizontal line.

[0038] This step can prevent the first wedge 15, the second wedge 16, and the middle wedge 14 from shifting position due to different degrees of wear, and maintain the horizontal consistency of each wedge.

[0039] Please see Figure 5-6As shown, this embodiment, based on the above embodiment, further includes:

[0040] The adjustment assembly includes a threaded hole 30, an adjusting rod 32, and a second support plate 34. The threaded hole 30 is opened at one end of the first support plate 22 near the middle wedge 14. The adjusting rod 32 is screwed into the threaded hole 30. The second support plate 34 is rotatably connected to one end of the adjusting rod 32, and the ball bearing 25 is rolled on the second support plate 34.

[0041] The adjustment assembly also includes a limiting hole 31 and a second limiting rod 33. The limiting hole 31 is opened at one end of the first support plate 22 near the middle wedge 14 and is located on both sides of the threaded hole 30. One end of the second limiting rod 33 is fixed to the side of the second support plate 34, and the other end is inserted into the limiting hole 31.

[0042] The threaded hole 30 serves as a connection, the adjusting rod 32 serves as an adjustment, the limiting hole 31 and the second limiting rod 33 serve as limiting, and the second support plate 34 serves as a support.

[0043] Working principle:

[0044] After the equipment has been used for a period of time, when there is a gap between the ball 25 and the limit block 20, the adjusting rod 32 in the threaded hole 30 can be rotated to move the second support plate 34 and at the same time move the second limit rod 33 in the limit hole 31, so that the ball 25 fits against the limit block 20.

[0045] This step allows for adjustment of the position of the ball bearing 25, avoiding frequent disassembly and assembly of the limit components. Accuracy can be restored simply by rotating the adjusting rod 32, reducing maintenance frequency and downtime.
