[0002] The rolling equipment includes a drive unit and at least two rollers. The drive unit applies a rotational force to the rollers to roll the raw material located between two adjacent rollers.
[0003] In related technologies, existing rolling equipment suffers from instability in the rolling process due to the roller shaft's radial clearance, resulting in poor rolling quality of the raw material. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rolling device based on gap-eliminating pre-tightening, which is beneficial to improving the stability of the rolls during the rolling process and improving the rolling quality of the raw materials.
[0005] This utility model also proposes a dry coating machine.
[0006] According to a first aspect of the present invention, a rolling apparatus based on gap-eliminating pre-tightening includes: a frame including at least two seats arranged side by side; a roll group including at least two rolls, the two rolls being respectively connected to the two seats, and the two ends of the rolls being rotatably connected to the two ends of the seats; a rolling drive assembly connected to the rolls, the rolling drive assembly being configured to provide radial pressure to the rolls toward adjacent rolls; and a gap adjustment assembly, with gap adjustment assemblies provided at both ends of the seats, the gap adjustment assemblies being located between and connected to the two adjacent seats, and being configured to adjust the gap between the two rolls; the rolling drive assembly and the gap adjustment assembly are arranged inward and outward along the axial direction of the rolls.
[0007] The rolling device based on gap elimination pre-tightening according to the present invention has at least the following beneficial effects: the roll group includes at least two rolls, each roll is connected to two seats, and the two ends of the rolls are rotatably connected to the two ends of the seats. Under the driving action of an external rotation drive assembly, the two rolls can be driven to rotate synchronously to achieve rolling of the raw material. Considering that when the rolls are rolling the raw material, under the reaction of the raw material, the middle part of the roll tends to bend away from the adjacent rolls, while the two ends of the rolls tend to bend obliquely towards the adjacent rolls, the rolling device based on gap elimination pre-tightening is further provided with a rolling drive assembly and a gap adjustment assembly. The gap adjustment assembly is located between and connected to the two adjacent seats, that is, the two seats can be adjusted through the gap adjustment assembly. The connection reduces roll sway and clearance, improving roll stability during the rolling process. The rolling drive assembly is connected to at least one roll to provide radial pressure to the roll towards the adjacent roll, i.e., to provide preload to the roll. The rolling drive assembly and the clearance adjustment assembly are arranged inward and outward along the axial direction of the roll, i.e., the rolling drive assembly is located closer to the center of the roll. By applying radial pressure to the roll, the rolling drive assembly can resist the tendency of the center of the roll to bend away from the adjacent roll, while the clearance adjustment assembly, by connecting to the ends of the roll, can resist the tendency of the two ends of the roll to bend obliquely towards the adjacent roll. This reduces the bending amplitude of the roll during the rolling process, thereby improving the shape stability of the roll during the rolling process and improving the rolling quality of the raw material.
[0008] According to some embodiments of the present invention, both ends of the base are provided with a first bearing seat and a second bearing seat, and both ends of the roll are provided with a first boss and a second boss arranged from the inside to the outside. The outer diameter of the first boss is larger than the outer diameter of the second boss. The outer periphery of the first boss is connected to a first bearing, which is rotatably connected to the first bearing seat. The outer periphery of the second boss is connected to a second bearing, which is rotatably connected to the second bearing seat.
[0009] According to some embodiments of the present invention, at least one of the two first bearing seats of the seat body is connected to the rolling drive assembly, and the gap adjustment assembly is connected to the second bearing seats of the two seats.
[0010] According to some embodiments of the present invention, the gap adjustment assembly includes a first inclined block, a second inclined block, and a fixing assembly. One end of the first inclined block is connected to a second bearing seat of one of the seats, and the other end of the first inclined block is provided with a first inclined surface. The second inclined block is provided with a second inclined surface that abuts against the first inclined surface. The first inclined surface and the second inclined surface have opposite inclination directions and complementary angles. The second inclined block can move closer to or further away from the first inclined block. The fixing assembly is used to fix the relative positions of the first inclined block and the second inclined block.
[0011] According to some embodiments of the present invention, the fixing component is a first linear actuator, which is connected to another adjacent body and is used to drive the second inclined block to move closer to or further away from the first inclined block.
[0012] According to some embodiments of the present invention, the gap adjustment component is a second linear actuator, which is connected to two adjacent seats to drive the two seats to move closer or further apart.
[0013] According to some embodiments of the present invention, the second linear actuator is a pneumatic cylinder or a hydraulic cylinder.
[0014] According to some embodiments of the present invention, the frame includes three or more bases, the roller group includes three or more rolls, the rolls correspond one-to-one with the bases and are connected, and a gap adjustment component is connected between two adjacent bases.
[0015] A dry coating machine according to a second aspect of the present invention includes a rolling device based on gap-eliminating pre-tightening as shown in any of the first aspects.
[0016] The dry coating machine according to the embodiments of the present invention has at least the following beneficial effects: The dry coating machine includes a rolling device based on gap elimination pre-tightening as shown in the first aspect. The roller group includes at least two rollers, which are respectively connected to two bases. The two ends of the rollers are respectively rotatably connected to the two ends of the bases. Under the driving action of an external rotation drive assembly, the two rollers can be driven to rotate synchronously to achieve roller pressing of the raw material. Considering that when the rollers are pressing the raw material, under the reaction of the raw material, the middle part of the rollers tends to bend away from the adjacent rollers, while the two ends of the rollers tend to bend obliquely towards the adjacent rollers, the rolling device based on gap elimination pre-tightening is further provided with a rolling drive assembly and a gap adjustment assembly. The gap adjustment assembly is located between two adjacent bases and connected to the two adjacent bases, that is, the two bases can... The connection via the gap adjustment assembly reduces roll sway and clearance, improving roll stability during the rolling process. The rolling drive assembly is connected to at least one roll to provide radial pressure that moves the roll closer to the adjacent roll, i.e., to provide preload. The rolling drive assembly and the gap adjustment assembly are arranged inward and outward along the axial direction of the roll, with the rolling drive assembly positioned closer to the center of the roll. By applying radial pressure to the roll, the rolling drive assembly resists the tendency of the center of the roll to bend away from the adjacent roll, while the gap adjustment assembly, connected to the ends of the roll, resists the tendency of both ends of the roll to bend obliquely towards the adjacent roll. This reduces the bending amplitude of the roll during the rolling process, thereby improving the shape stability of the roll and enhancing the rolling quality of the raw material.
[0017] According to some embodiments of the present invention, the dry coating machine further includes a feeding assembly, wherein a rolling space is constructed between two adjacent rollers, and the feeding assembly is configured to supply raw materials to the rolling space.

[0035] Reference Figures 1 to 3 As shown, an embodiment of the present invention is a rolling device based on gap elimination pre-tightening, comprising: a frame 100, a roll 200, a rolling drive assembly 300, and a gap adjustment assembly 400.
[0036] Reference Figure 1 , Figure 2 and Figure 3 As shown, the frame 100 includes a frame body and two seats 110 arranged side by side, one above the other. Both seats 110 are connected to the frame body, which provides support for the seats 110. The roller assembly includes two rollers 200 arranged vertically and parallel to each other. The two rollers 200 are connected to the two seats 110 respectively, and their ends are rotatably connected to the ends of the seats 110 respectively. Under the driving action of an external rotary drive assembly, the two rollers 200 can be driven to rotate synchronously to achieve rolling compression of the raw material.
[0037] Reference Figure 3As shown, considering that when the roll 200 is rolling the raw material, under the reaction of the raw material, the middle part of the roll 200 tends to bend away from the adjacent roll 200, while the two ends of the roll 200 tend to bend towards the adjacent roll 200, the rolling device based on gap elimination pre-tightening is further provided with a rolling drive assembly 300 and a gap adjustment assembly 400.
[0038] Reference Figure 1 , Figure 2 and Figure 3 As shown, the rolling drive assembly 300 is connected to both ends of the roll 200. The rolling drive assembly 300 is configured to provide radial pressure to the roll 200 to move closer to the adjacent roll 200, that is, to provide preload to the roll 200. Both ends of the seat 110 are provided with gap adjustment assemblies 400. The gap adjustment assemblies 400 are located between and connected to the two adjacent seats 110. The gap adjustment assemblies 400 are configured to adjust the gap between the two rolls 200. At the same end of the roll 200, the rolling drive assembly 300 and the gap adjustment assembly 400 are arranged in an inward and outward manner along the axial direction of the roll 200.
[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown, the rolling drive assembly 300 is positioned closer to the center of the roll 200. The rolling drive assembly 300 provides preload to the roll 200 by applying radial pressure, which resists the tendency of the center of the roll 200 to bend away from the adjacent roll 200. Meanwhile, the gap adjustment assembly 400, connected to the end of the roll 200, resists the tendency of both ends of the roll 200 to bend towards the adjacent roll 200. This reduces the bending amplitude of the roll 200 during the rolling process, which helps to reduce or eliminate the radial clearance of the roll 200. This allows the roll 200 to work stably without radial offset while enhancing its radial rigidity. This makes the overall structure more compact and rigid, thereby improving the shape stability of the roll 200 during the rolling process and improving the rolling quality of the raw material.
[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, it should be noted that the rolling drive assembly 300 may be one or more support members that provide support or pressure to the roll 200, thereby applying a supporting force or pressure to the roll 200 and a radial force that moves the roll 200 toward adjacent rolls 200. Specifically, the rolling drive assembly 300 may be a shaft that is directly or indirectly connected to the roll 200, thereby applying a radial pressure that moves the roll 200 toward adjacent rolls 200, i.e., providing preload to the roll 200.
[0041] It should be understood that in some other embodiments, multiple seats 110 are arranged in a horizontal direction, and multiple rollers 200 are arranged in a planar manner in a horizontal direction.
[0042] It should be understood that in some other embodiments, the rolling drive assembly 300 may act on the middle of the roll 200 to resist the tendency of the middle of the roll 200 to bend away from the adjacent roll 200.
[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, both ends of the seat 110 are provided with a first bearing seat 111 and a second bearing seat 112. Taking the two ends of the seat 110 as arranged in a left-right manner as an example, the right end of the seat 110 is provided with a first bearing seat 111 and a second bearing seat 112 arranged in a left-right manner, and the left end of the seat 110 is also provided with a first bearing seat 111 and a second bearing seat 112 arranged in a right-left manner.
[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, the two ends of the adaptable roll 200 are arranged in the left-right direction. Both ends of the roll 200 are provided with a first boss 210 and a second boss 220 arranged from the inside out. That is, the left end of the roll 200 is provided with a first boss 210 and a second boss 220 arranged from right to left, and the right end of the roll 200 is provided with a first boss 210 and a second boss 220 arranged from left to right.
[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, both the first boss 210 and the second boss 220 are cylindrical. The outer diameter of the first boss 210 is larger than that of the second boss 220. A first bearing 510 is connected to the outer periphery of the first boss 210, and the first bearing 510 is rotatably connected to the first bearing housing 111. A second bearing 520 is connected to the outer periphery of the second boss 220, and the second bearing 520 is rotatably connected to the second bearing housing 112. The roll 200 is rotatably connected to the first bearing housing 111 via the first bearing 510 and to the second bearing housing 112 via the second bearing 520 to ensure the smooth rotation of the roll 200. The second bearing 520 can be used as a thrust bearing to achieve axial positioning of the roll 200.
[0046] Reference Figure 1 , Figure 2 and Figure 3As shown, it can be understood that both first bearing seats 111 of the seat 110 are connected to the rolling drive assembly 300, meaning that the rolling drive assembly 300 can act on the two first bearing seats 111 of the same seat 110. Taking two upper and lower rolls 200 as an example, the rolling drive assembly 300 can act on the two first bearing seats 111 of the upper seat 110, thereby providing downward radial pressure to the upper roll 200, and the rolling drive assembly 300 can act on the two first bearing seats 111 of the lower seat 110, thereby providing upward radial pressure to the lower roll 200.
[0047] Reference Figure 1 , Figure 2 and Figure 3 As shown, the gap adjustment assembly 400 is connected to the second bearing seat 112 of the two seats 110, thereby applying a supporting force to the roll 200 to resist the end bending of the roll 200 during the rolling process.
[0048] Reference Figure 1 , Figure 2 and Figure 3 As shown, in Figure 3 In the diagram, the dashed line along the radial direction of the roll 200 represents the stress line, illustrating the stress distribution of the rolling device based on backlash elimination preload. At the same end of the roll 200, the rolling drive assembly 300 and the gap adjustment assembly 400 are staggered in the axial direction, not located in the same axial position. This allows the pressure at the end of the roll 200 to be concentrated at the gap adjustment assembly 400 and the second bearing 520, which helps to eliminate the radial backlash of the roll 200. This enables the first bearing 510 to work stably without radial offset, while also enhancing the radial rigidity of the roll 200, resulting in a more compact and rigid overall structure.
[0049] Reference Figure 1 , Figure 2 and Figure 3As shown, it can be understood that the gap adjustment assembly 400 includes a first inclined block 410, a second inclined block 420, and a fixing assembly 430. One end of the first inclined block 410 is connected to the second bearing seat 112 of one of the seats 110. The other end of the first inclined block 410 is provided with a first inclined surface. The second inclined block 420 is provided with a second inclined surface that abuts against the first inclined surface. The first inclined surface and the second inclined surface have opposite inclination directions and complementary angles. The second inclined block 420 can move closer to or further away from the first inclined block 410. By contacting the second inclined surface of the second inclined block 420 with the first inclined surface of the first inclined block 410, as the contact area between the second inclined surface and the first inclined surface increases, the two seats 110 can be driven to move away from each other. As the contact area between the second inclined surface and the first inclined surface decreases, the two seats 110 can be driven to move closer to each other. That is, the seat 110 connected to the first inclined block 410 is driven to move away from or closer to the other seat 110, thereby realizing the function of adjusting the gap between the two seats 110.
[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, the fixing component 430 is used to fix the relative positions of the first inclined block 410 and the second inclined block 420. When the user adjusts the positions of the first inclined block 410 and the second inclined block 420 to a preset position, so that the gap between the two seats 110 reaches a preset distance, the user can fix the relative position relationship of the first inclined block 410 and the second inclined block 420 through the fixing component 430, so that the gap between the two rollers 200 is fixed to a preset distance, so as to adapt to the rolling requirements of different types of raw materials.
[0051] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that, specifically, the fixing component 430 is a first linear actuator, the first inclined block 410 is fixedly connected to the second bearing seat 112 of one of the seats 110, the second inclined block 420 is located above the second bearing seat 112 of the other seat 110, the first linear actuator is connected to the adjacent other seat 110, and the first linear actuator is connected to the second inclined block 420 to drive the second inclined block 420 closer to or further away from the first inclined block 410. Through the contact between the second inclined surface of the second inclined block 420 and the first inclined surface of the first inclined block 410, as the contact area between the second inclined surface and the first inclined surface increases or decreases, the seat 110 connected to the first inclined block 410 is driven further away from or closer to the other seat 110, thereby realizing the function of adjusting the gap between the two seats 110. The first linear actuator drives the second inclined block 420 to a preset position and then stops, thus fixing the relative positional relationship between the first inclined block 410 and the second inclined block 420.
[0052] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the frame 100 may include a frame body. Taking two seats 110 arranged vertically as an example, one seat 110 is fixedly connected to the frame body, and the other seat 110 is slidably connected to the frame body in the vertical direction. The frame body can guide and limit the other seat 110, thereby ensuring the stability of the two seats 110 as they move closer or further apart. The frame body can guide and limit the sliding connection of the seat 110 through slide rails, sliders, or guide rods.
[0053] It should be noted that the first linear actuator can be a linear drive mechanism such as a cylinder, hydraulic cylinder, or lead screw and slider mechanism.
[0054] It should be understood that in some other embodiments, the gap adjustment component 400 is a second linear actuator. Taking the two seats 110 arranged vertically as an example, the two ends of the second linear actuator are respectively connected to the two adjacent seats 110 to drive the two seats 110 to move closer or further apart.
[0055] The second linear actuator can apply an upward force to the upper seat 110 and a downward force to the lower seat 110, thereby driving the two seats 110 away from each other. Similarly, the second linear actuator can reduce or eliminate the upward force on the upper seat 110 and the downward force on the lower seat 110, thereby driving the two seats 110 closer to each other. Through direct force in the vertical direction, the second linear actuator can better support the radial force of the roll 200, thereby reducing the sway of the roll 200 and reducing or eliminating the clearance of the roll 200 during the rolling process.
[0056] Specifically, the second linear actuator is a pneumatic cylinder or a hydraulic cylinder, which can adjust the gap between the two seats 110 and better support the radial force of the roll 200 to reduce the sway of the roll 200 and reduce or eliminate the clearance of the roll 200 during the rolling process.
[0057] Reference Figure 3 , Figure 4 and Figure 5 As shown, it should be understood that in some other embodiments, the frame 100 includes three seats 110. Taking the three seats 110 arranged side by side from top to bottom as an example, the roller group includes three rollers 200. The rollers 200 correspond one-to-one with the seats 110, and the rollers 200 are rotatably connected to the seats 110.
[0058] Reference Figure 3 , Figure 4 and Figure 5As shown, gap adjustment components 400 are respectively provided at both ends of the seat 110, and gap adjustment components 400 are connected between two adjacent seat 110s. That is, two gap adjustment components 400 are provided between the upper seat 110 and the middle seat 110, and the two gap adjustment components 400 are respectively provided at the upper ends of the two second bearing seats 112 of the middle seat 110. Two gap adjustment components 400 are provided between the middle seat 110 and the lower seat 110, and the two gap adjustment components 400 are respectively provided at the lower ends of the two second bearing seats 112 of the middle seat 110.
[0059] Reference Figure 3 , Figure 4 and Figure 5 As shown, the rolling drive assembly 300 can be connected to the two first bearing seats 111 of the upper seat 110 to provide downward radial pressure to the upper roll 200. The rolling drive assembly 300 can also be connected to the two first bearing seats 111 of the lower seat 110 to provide upward radial pressure to the lower roll 200. Under the radial pressure of the upper roll 200 and the lower pressure roll, the middle roll 200 can also remain stable.
[0060] Reference Figure 1 , Figure 2 and Figure 3As shown, a dry coating machine according to an embodiment of the present invention includes a rolling device based on gap-eliminating pre-tightening as shown in any of the above embodiments. The roll assembly includes at least two rolls 200, each connected to two seats 110. The two ends of each roll 200 are rotatably connected to the two ends of each seat 110. Driven by an external rotary drive assembly, the two rolls 200 can rotate synchronously to roll the raw material. Considering that when rolling the raw material, the middle of the roll 200 tends to bend away from the adjacent roll 200 under the reaction force of the material, while the two ends of the roll 200 tend to bend closer to the adjacent roll 200, this backlash-eliminating preload rolling device adds a rolling drive assembly 300 and a gap adjustment assembly 400. The gap adjustment assembly 400 is located between and connected to the two adjacent seats 110, meaning the two seats 110 can be connected via the gap adjustment assembly 400. This reduces the sway and backlash of the rolls 200, improving the roll speed. To ensure stability during the rolling process, the rolling drive assembly 300 is connected to at least one roll 200 to provide radial pressure to the roll 200 towards the adjacent roll 200, i.e., to provide preload to the roll 200. The rolling drive assembly 300 and the gap adjustment assembly 400 are arranged inward and outward along the axial direction of the roll 200, i.e., the rolling drive assembly 300 is located closer to the center of the roll 200. By applying radial pressure to the roll 200, the rolling drive assembly 300 can resist the tendency of the center of the roll 200 to bend away from the adjacent roll 200. The gap adjustment assembly 400, by connecting to the ends of the roll 200, can resist the tendency of the two ends of the roll 200 to bend towards the adjacent roll 200. This reduces the bending amplitude of the roll 200 during the rolling process, thereby improving the shape stability of the roll 200 during the rolling process and improving the rolling quality of the raw material.
[0061] Reference Figure 1 , Figure 2 and Figure 3 As shown, the dry coating machine also includes a feeding assembly. A rolling space is constructed between two adjacent rollers 200. The rolling space includes a rolling inlet and a rolling outlet. The feeding assembly is configured to supply raw materials to the inlet of the rolling space. Specifically, the raw material can be powder. Under the driving action of an external rotary drive assembly, the two adjacent rollers 200 rotate synchronously to roll the raw material located in the rolling space, that is, to roll the raw material to form a sheet-like electrode. Therefore, this dry coating machine can be used to manufacture electrodes for solid-state batteries to improve the production quality of the electrodes.
[0062] Reference Figure 1 , Figure 2 and Figure 3As shown, the feeding component can be a weighing and unloading device, a belt conveyor, or other conveying device. Its structure is a conventional technical means in this field and will not be described in detail here.
[0063] It should be understood that in some other embodiments, the feeding assembly can transport the substrate with the electrode coating and the solid electrolyte membrane together to the rolling space between two adjacent rollers 200. That is, the feeding assembly can be used to feed the membrane material. Under the rolling action of the two rollers 200, the substrate with the electrode coating and the solid electrolyte membrane are bonded together to form an electrode sheet with the electrode coating and the solid electrolyte membrane. That is, the dry coating machine can be used to manufacture the electrode sheet of solid-state battery to improve the production quality of the electrode sheet.
[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
