Description

Technical Field

[0001] This utility model relates to the field of film forming rollers, and in particular to a dry film forming roller that effectively eliminates vibration. Background Technology

[0002] Dry film-forming rollers are primarily used in the production of lithium-ion battery separators. They produce PP / PE microporous membranes, such as the Celgard 2500 model, using a dry roll pressing process. The thickness can be precisely controlled down to 25μm, and these membranes are used for separation between the positive and negative electrodes of the battery. Dry film-forming rollers are also used in the production of solid-state battery electrodes, pressing powder materials into self-supporting films. For example, Mannster's dry roll pressing equipment can efficiently produce high-energy-density solid-state battery electrodes. Currently available dry film forming rollers use a structure design where the drive unit is directly connected to the roller body, meaning the roller and reducer are directly linked. Theoretically, this connection method can meet the accuracy requirements, but in practice, it is difficult to achieve the required accuracy after assembly. Even if the accuracy requirements are met after assembly, the assembly process is very time-consuming and extremely difficult. This is because even a slight runout of the reducer's output shaft will directly cause the roller to runout, and the roller's runout will directly affect the film's accuracy, resulting in poor dry film forming effect, low yield, and inability to meet the needs of industrial development. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dry film forming roller that effectively eliminates jumping.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the dry film forming roller that effectively eliminates jumping includes a speed reducer, a roller rotation drive device is connected to one side of the speed reducer, a rotating shaft is provided on the other side of the speed reducer, an active roller is provided on the rotating shaft, a first slide is mounted on the output shaft of the speed reducer, a second slide is mounted on the end of the rotating shaft facing the first slide, a slider is installed between the first slide and the second slide, and a transmission component is mounted on the side of the second slide facing the slider.

[0005] Preferably, the first slide block has a first groove in the radial direction on the side of the slide block facing the slider.

[0006] Preferably, the second slide block has a second groove in the radial direction on the side facing the slider, and the transmission component is installed in the second groove.

[0007] Specifically, the slider has a raised strip in the radial direction on the side facing the first slide block that is adapted to be installed in the first slide groove.

[0008] Specifically, the slider is provided with a third slide groove in the radial direction on the side facing the second slide block, which is adapted to be installed with the transmission component. The third slide groove is perpendicular to the protrusion.

[0009] Preferably, the center of the second slide has a first mounting hole along the axial direction.

[0010] Preferably, the slider has a second mounting hole at its center along the axial direction.

[0011] Preferably, at least one cylindrical heating element is installed at the end of the rotating shaft away from the slider.

[0012] Preferably, a first bearing is fitted on one end of the rotating shaft, and a second bearing is fitted on the other end of the rotating shaft.

[0013] Specifically, the first bearing is connected and installed to the reducer via a connecting bracket.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. By installing a first slide block on the output shaft of the reducer, installing a second slide block on the end of the shaft facing the first slide block, and installing a slider between the first and second slide blocks, a first groove is provided radially on the side of the first slide block facing the slider, and a protrusion adapted to the first groove is provided radially on the side of the slider facing the first slide block. When the output shaft of the reducer swings slightly, if the first slide block moves laterally along the direction of the first groove, the protrusion of the slider can slide in the first groove of the first slide block, and the first slide block and the slider move out of alignment, thus avoiding the influence of the lateral movement of the first slide block on the slider, and thus avoiding the first slide block from causing the slider to move laterally.

[0015] 2. It has a transmission component installed on the side of the second slide facing the slider and a third slide groove installed radially on the side of the slider facing the second slide, which is adapted to the transmission component. The third slide groove is perpendicular to the convex strip. When the output shaft of the reducer swings slightly, if the first slide moves laterally in a direction perpendicular to the first slide groove, the first slide will drive the slider to move laterally. The transmission component fixedly installed on the second slide will slide in the third slide groove, causing the slider and the second slide to move out of alignment. This avoids the influence of the slider's lateral movement on the second slide, thereby preventing the slider from driving the second slide to move laterally, and ultimately preventing the reducer output shaft from swinging and causing the rotating shaft to swing.

[0016] 3. Its overall structural design enables automatic adjustment when the output shaft of the reducer oscillates, ensuring zero-error transmission to the drive roller when the reducer oscillates. This avoids the output shaft of the reducer oscillating and drives the rotating shaft to oscillate, ensuring the smoothness of the rotating shaft and thus ensuring the uniformity and precision of the film thickness. It not only has the advantages of good dry film forming effect and high yield, but also achieves simple installation, easy operation, quick assembly and disassembly, convenient maintenance, time and labor saving, and meets the high precision requirements of roll forming. It effectively solves the problem of poor dry film forming effect and low yield caused by the structure design of the dry film forming rollers on the market, which uses a drive device directly connected to the roller body. This is because slight vibration of the output shaft of the reducer directly drives the roller vibration. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Reference Figures 1 to 3 As shown, this utility model discloses an effective dry film-forming roller that eliminates bounce, comprising a speed reducer 1, a roller rotation drive device 2 connected to one side of the speed reducer 1, a rotating shaft 3 on the other side of the speed reducer 1, an active roller 4 on the rotating shaft 3, a first slide 5 mounted on the output shaft 9 of the speed reducer 1, a second slide 6 mounted on the end of the rotating shaft 3 facing the first slide 5, a slider 7 mounted between the first slide 5 and the second slide 6, and a transmission component 8 mounted on the side of the second slide 6 facing the slider 7.

[0029] In this embodiment, the roller rotation drive device 2 is connected to the reducer 1 via a coupling 21, and the roller rotation drive device 2 is a servo motor.

[0030] Reference Figure 2 and Figure 3 As shown, the first slide block 5 has a first groove 51 in the radial direction on the side of the slide block 7 facing the slide block 7.

[0031] Reference Figure 2 , Figure 4 and Figure 5 As shown, the slider 7 has a protrusion 71 in the radial direction on the side facing the first slide block 5, which is adapted to be installed in the first slide groove 51.

[0032] In this embodiment, the first groove 51 can be a cuboid or a semi-cylinder, and the protrusion 71 can be a cuboid or a semi-cylinder, etc., that are adapted to the concave shape of the first groove 51.

[0033] Reference Figures 2 to 5As shown, by adopting the above technical solution, after the first slide block 5 and the slider 7 are connected and installed, when the output shaft 9 of the reducer 1 swings slightly, if the first slide block 5 moves laterally along the direction of the first slide groove 51, the protrusion 71 of the slider 7 can slide in the first slide groove 51 of the first slide block 5. The first slide block 5 and the slider 7 move out of alignment to make appropriate adjustments automatically, avoiding the influence of the lateral movement of the first slide block 5 on the slider 7, and thus avoiding the first slide block 5 from causing the slider 7 to move laterally.

[0034] Reference Figure 2 and Figure 6 As shown, the second slide block 6 has a second slide groove 61 in the radial direction on the side of the slide block 7 facing the slide block 7, and the transmission component 8 is installed in the second slide groove 61.

[0035] In this embodiment, the second slide groove 61 can be a cuboid or a semi-cylinder, and the shape of the side of the transmission member 8 opposite to the second slide groove 61 can be a cuboid or a semi-cylinder, etc., that matches the concave shape of the second slide groove 61.

[0036] Reference Figure 4 and Figure 5 As shown, the slider 7 is provided with a third slide groove 72 in the radial direction on the side facing the second slide block 6, which is adapted to be installed with the transmission component 8. The third slide groove 72 is perpendicular to the protrusion 71.

[0037] In this embodiment, the third slide groove 72 can be a cuboid or a semi-cylinder, and the shape of the side of the transmission member 8 opposite to the third slide groove 72 can be a cuboid or a semi-cylinder that matches the concave shape of the third slide groove 72.

[0038] By adopting the above technical solution, after the second slide block 6 and the slider 7 are installed together, when the output shaft 9 of the reducer 1 swings slightly, if the first slide block 5 moves laterally in a direction perpendicular to the first slide groove 51, the first slide block 5 will drive the slider 7 to move laterally. Since the third slide groove 72 is perpendicular to the convex strip 71, the transmission component 8 fixedly installed on the second slide block 6 slides in the third slide groove 72. The slider 7 and the second slide block 6 move out of alignment to make appropriate adjustments automatically, avoiding the influence of the lateral movement of the slider 7 on the second slide block 6, thereby avoiding the slider 7 driving the second slide block 6 to move laterally, and finally avoiding the reducer 1 output shaft 9 from swinging and causing the rotating shaft 3 to swing, ensuring the smoothness of the rotation of the rotating shaft 3, and thus ensuring the uniformity and accuracy of the film thickness.

[0039] Reference Figure 6 As shown, the second slide block 6 has a first mounting hole 62 at its center along the axial direction.

[0040] By adopting the above technical solution, when the bolt is installed in the first mounting hole 62, the second slide 6 can be fixed to the end of the rotating shaft 3. When the second slide 6 is damaged and needs maintenance, the bolt can be loosened to quickly remove the second slide 6 for replacement. Maintenance is quick, convenient, easy to operate, and saves time and effort.

[0041] Reference Figure 4 and Figure 5 As shown, the slider 7 has a second mounting hole 73 at its center along the axial direction.

[0042] By adopting the above technical solution, by passing a round bar through the second mounting hole 73 and the first mounting hole 62 in sequence, the slider 7 and the second slide block 6 can be quickly positioned and connected, making the installation of the slider 7 and the second slide block 6 quick and convenient.

[0043] Reference Figure 7 As shown, at least one cylindrical heating tube 10 is installed in the end of the rotating shaft 3 away from the slider 7.

[0044] Reference Figure 7 and Figure 8 As shown, by adopting the above technical solution, since the cylindrical heating tube 10 is connected to an external power source through the wire 11, the cylindrical heating tube 10 is heated by supplying power to the cylindrical heating tube 10, and the heat is conducted to the rotating shaft 3 and the active roller 4 on it. When the active roller 4 is heated to the predetermined temperature, the roll forming process can be realized. The cylindrical heating tube 10 is a straight rod shape, and the deformation after heating is small. When the cylindrical heating tube 10 is damaged, it can be easily removed from the rotating shaft 3, realizing quick and convenient replacement, simple maintenance, and saving time and effort.

[0045] Reference Figure 1 and Figure 2 As shown, a first bearing 12 is fitted on one end of the rotating shaft 3, and a second bearing 13 is fitted on the other end of the rotating shaft 3.

[0046] Reference Figure 1 As shown, the first bearing 12 is connected and installed to the reducer 1 via a connecting bracket 14.

[0047] By adopting the above technical solution, the first bearing 12 and the second bearing 13 provide support for the rotation of the rotating shaft 3, which ensures the good stability of the rotation of the rotating shaft 3, so as to ensure the high processing accuracy and good processing effect of the active roller 4 for film forming, and thus ensure the high yield of film products.

[0048] Its overall structural design avoids the swinging of the rotating shaft 3 caused by the swinging of the output shaft 9 of the reducer 1, ensuring the smooth rotation of the rotating shaft 3, and thus ensuring the uniformity and accuracy of the film thickness. It has the advantages of good dry film forming effect, high yield and convenient maintenance. It effectively solves the problem of poor dry film forming effect and low yield caused by the structure design of the dry film forming rollers on the market, which adopts the structure design of the drive device directly connected to the roller body. The slight jump of the output shaft 9 of the reducer 1 will directly drive the jump of the roller.

All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
