Description

Technical Field

[0001] This application belongs to the field of new energy battery processing equipment technology, and in particular relates to a roller pressing device. Background Technology

[0002] In the processing of new energy batteries (such as lithium batteries, zinc batteries, solid-state batteries, etc., which are composed of multiple cells), it is necessary to use a rolling device to roll the materials that make up the cells, so that the materials are compressed to a preset thickness.

[0003] Roller pressing devices typically include an upper roller assembly and a lower roller assembly. There is a gap between the upper roller of the upper roller assembly and the lower roller of the lower roller assembly. During roller pressing, the upper roller and the lower roller rotate synchronously. The material passes between the upper roller and the lower roller and is compressed to a preset thickness by the squeezing of the upper roller and the lower roller.

[0004] However, in actual production, the upper pressure roller is relatively heavy. During the rolling process, there may be insufficient control precision of the downward pressing distance or the upper pressure roller may tilt to one side, which makes it difficult to accurately control the rolling thickness of the material, ultimately resulting in a large rolling processing error. Utility Model Content

[0005] The purpose of this application is to provide a roller pressing device to solve the aforementioned problems existing in the existing roller pressing devices.

[0006] To achieve this objective, the following technical solution is adopted in this application:

[0007] This application discloses a roller pressing device, which includes a frame, an upper pressing roller mechanism, a lower pressing roller mechanism, a first driving component, and a detection mechanism, wherein...

[0008] The lower pressure roller mechanism is fixedly installed on the frame, and the upper pressure roller mechanism is vertically installed on the frame and located above the lower pressure roller mechanism. There is a roller gap between the upper pressure roller mechanism and the lower pressure roller mechanism for material to pass through and extending in the first horizontal direction.

[0009] The drive end of the first drive member is connected to the upper pressure roller mechanism. The first drive member is configured to drive the upper pressure roller mechanism to rise and fall, so as to press the material moving in the gap between the upper and lower pressure roller mechanisms through the cooperation of the upper and lower pressure roller mechanisms.

[0010] The detection mechanism is set on the upper pressure roller mechanism and / or the lower pressure roller mechanism. The detection mechanism is configured to detect the height of the roller gap in real time to determine whether the material has been rolled to a preset thickness.

[0011] The material includes at least an electrode sheet or a composite of multiple electrode sheets.

[0012] The roller pressing device proposed in this application is equipped with a detection mechanism on the upper and / or lower roller pressing mechanisms. The detection mechanism can detect the height of the roller pressing gap between the upper and lower roller pressing mechanisms in real time, eliminating the need for repeated manual measurements, thus improving roller pressing efficiency. This facilitates precise control of the roller pressing thickness of the material and improves the roller pressing accuracy of the material.

[0013] Optionally, the upper pressure roller mechanism includes a second drive member, two upper roller seats and an upper pressure roller. The two upper roller seats are vertically and flexibly mounted on the frame at intervals along a first horizontal direction. The upper pressure roller extends along the first horizontal direction. The roller shaft of the upper pressure roller is rotatably mounted on the two upper roller seats at both ends in the first horizontal direction. The frame is provided with a clearance notch for avoiding the roller shaft of the upper pressure roller. The fixed end of the second drive member is mounted on one of the upper roller seats, and the driving end of the second drive member is connected to the roller shaft of the upper pressure roller. The second drive member is configured to drive the upper pressure roller to rotate.

[0014] The lower pressure roller mechanism includes a third drive member, two lower roller seats and a lower pressure roller. The two lower roller seats are fixedly mounted on the frame at intervals along a first horizontal direction. Each lower roller seat corresponds to an upper roller seat. The lower roller seat is located directly below the corresponding upper roller seat. The lower pressure roller extends along the first horizontal direction. The roller shaft of the lower pressure roller is rotatably mounted on the two lower roller seats at both ends of the first horizontal direction. The fixed end of the third drive member is mounted on one of the lower roller seats. The driving end of the third drive member is connected to the roller shaft of the lower pressure roller. The third drive member is configured to drive the lower pressure roller to rotate.

[0015] A roller gap is formed between the upper and lower pressure rollers, and the upper and lower pressure rollers rotate in the same direction.

[0016] By mounting two upper roller seats at intervals on the frame and rotatably mounting the two ends of the upper pressure roller shaft on the two upper roller seats respectively, and driving the upper pressure roller to rotate through a second drive component, the upper pressure roller is lifted and rotated relative to the frame. This provides a simple, stable, and reliable upper pressure roller mechanism. The floating design of the upper pressure roller also prevents the material from being excessively squeezed. By fixing two lower roller seats at intervals on the frame and rotatably mounting the two ends of the lower pressure roller shaft on the two lower roller seats respectively, and driving the lower pressure roller to rotate through a third drive component, the lower pressure roller is rotated relative to the frame. This provides a simple, stable, and reliable lower pressure roller mechanism.

[0017] Optionally, the testing mechanism includes two testing components, which are respectively arranged between a set of upper roller seats and a corresponding lower roller seat. Each testing component includes a dial indicator and a support, wherein:

[0018] The dial indicator is fixedly mounted on the upper roller seat, and the bracket is mounted on the lower roller seat with adjustable height. A reference surface is set horizontally on the bracket, and the measuring rod of the dial indicator is vertically downward and abuts against the reference surface.

[0019] Alternatively, the dial indicator is fixedly mounted on the lower roller seat, and the bracket is mounted on the upper roller seat with adjustable height, with the measuring rod of the dial indicator pointing vertically upward against the reference surface;

[0020] The reference plane heights of the supports for both detection components are the same.

[0021] By setting a detection component between each set of upper roller seats and the corresponding lower roller seats, two detection points at the same reference height are formed between the upper and lower pressure rollers, which can detect whether the upper roller seat is tilted, thus improving the detection accuracy of the detection mechanism. The height of the roller gap is detected by the cooperation of dial indicator and bracket, which has the advantages of high measurement accuracy, wide applicability, and high stability and reliability. At the same time, the height of the bracket is adjustable, which can adjust the reference surface of the detection as needed.

[0022] Optionally, a limit component is provided between the upper roller seat and the corresponding lower roller seat, and the limit component is configured to limit the downward stroke of the upper roller seat.

[0023] By setting a limiting component between the upper roller seat and the corresponding lower roller seat to limit the downward stroke of the upper roller seat, the two ends of the upper pressure roller can be limited during the material rolling process, thereby ensuring the movement stroke and horizontal state of the upper pressure roller and further improving the rolling accuracy of the material.

[0024] Optionally, the limiting assembly includes a base, a support, an adjusting rod, an adjusting seat, and a locking element, wherein,

[0025] The base is fixedly installed on the lower roller seat. A limit groove is opened on the base. The support is configured to support the upper roller seat. The bottom surface of the support is a wedge surface. The bottom of the limit groove is an inclined surface that matches the wedge surface. The support can be installed in the limit groove by moving along the inclined surface.

[0026] The adjusting seat is fixed on the lower roller seat, the adjusting rod is rotatably inserted through the adjusting seat, the adjusting rod is connected to the support, and the locking element is installed on the adjusting seat. The locking element is configured to lock or release the adjusting rod relative to the adjusting seat.

[0027] When the locking mechanism releases the adjusting rod, the adjusting rod is rotated to drive the support component to move along the inclined plane, and then the support component is raised or lowered through the cooperation of the wedge surface and the inclined plane.

[0028] By cooperating with the inclined wedge of the support member and the inclined surface of the limiting groove, the translational movement of the support member along the inclined surface is transformed into the lifting movement of the support member. The structure is simple and the operation is stable and reliable. By cooperating with the adjusting rod and the adjusting seat, the support member is driven to translate along the inclined surface, which is convenient and labor-saving. The locking component locks the adjusting rod relative to the adjusting seat to prevent the adjusting rod from shifting when not in operation.

[0029] Optionally, the roller pressing device also includes a fourth driving member. The fixed end of the fourth driving member is mounted on the lower roller seat, and the driving end of the fourth driving member is connected to the upper roller seat corresponding to the lower roller seat. The fourth driving member is configured to drive the upper roller seat to rise so that the upper roller seat is lifted away from the support member at a preset height.

[0030] By setting a fourth driving component, the upper roller seat can be lifted away from the support component, making it convenient to adjust the height of the support surface of the support component.

[0031] Optionally, pressure sensors are installed on both upper roller seats. There are two first driving units, and the driving ends of the two first driving units are respectively connected to the two pressure sensors. The two pressure sensors are configured to detect the pressure applied to the upper roller seat by the corresponding first driving unit.

[0032] By installing pressure sensors on both upper roller seats, the pressure applied by the first drive component to the upper roller seats is automatically detected, thereby controlling the pressure applied to the two upper roller seats to be balanced, so that the pressure applied by the upper pressure roller is uniform, which is beneficial to improving the rolling accuracy of the material.

[0033] Optionally, the upper pressure roller and / or the lower pressure roller are provided with heating elements, which are configured to heat the upper pressure roller and / or the lower pressure roller.

[0034] By installing heating components on the upper and / or lower pressure rollers, the material can be heated while being pressed by the rollers.

[0035] Optionally, the roller pressing device further includes a first conveying mechanism disposed on a first side of the gap in a second horizontal direction. The first conveying mechanism is configured to convey material toward the roller pressing gap, wherein the first horizontal direction is perpendicular to the second horizontal direction.

[0036] By setting up a first conveying mechanism, materials are automatically conveyed into the gap between the rollers, improving work efficiency and preventing personnel injury.

[0037] Optionally, the roller pressing device further includes a second conveying mechanism disposed on a second side of the roller pressing gap in a second horizontal direction, and the second conveying mechanism is configured to convey material toward the roller pressing gap;

[0038] The first conveying mechanism and the second conveying mechanism convey materials in the same direction and at the same speed.

[0039] By setting up a second conveying mechanism and configuring it to convey materials in the same direction and at the same speed as the first conveying mechanism, the material can be repeatedly conveyed to the roller gap, thereby achieving multiple repeated roller pressing of the material and improving the roller pressing efficiency.

[0052] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] In the processing of new energy batteries, the raw materials that make up the battery cells need to be compressed using a rolling device to achieve a preset thickness. The rolling device typically includes an upper pressure roller assembly and a lower pressure roller assembly. There is a gap between the upper pressure roller of the upper assembly and the lower pressure roller of the lower assembly. During rolling, the upper and lower pressure rollers rotate synchronously, and the material passes between them, being compressed to the preset thickness through the pressure of the rollers. However, in actual production, the upper pressure roller is relatively heavy, and the flatness of the material may vary at different locations during the rolling process. During the rolling process, there may be insufficient precision in controlling the downward pressure distance or the upper pressure roller may be tilted, making it difficult to accurately control the rolled thickness and ultimately resulting in a large rolling processing error.

[0054] Therefore, this application proposes a roller pressing device, please refer to [link to relevant documentation]. Figure 1 As shown, the roller pressing device proposed in this application embodiment includes a frame 10, an upper roller mechanism 20, a lower roller mechanism 30, a first driving member 40, and a detection mechanism 50. The lower roller mechanism 30 is fixedly installed on the frame 10, and the upper roller mechanism 20 is vertically and flexibly installed on the frame 10 and located above the lower roller mechanism 30. A passage for material to pass through is provided between the upper roller mechanism 20 and the lower roller mechanism 30 along a first horizontal direction. Figure 1 A roller gap 11 extending in the X direction (as shown in the image); the driving end of a first driving member 40 is connected to an upper pressure roller mechanism 20, and the first driving member 40 is configured to drive the upper pressure roller mechanism 20 to rise and fall, so as to roll the material moving in the roller gap 11 through the cooperation of the upper pressure roller mechanism 20 and the lower pressure roller mechanism 30; a detection mechanism 50 is disposed on the upper pressure roller mechanism 20 and / or the lower pressure roller mechanism 30, and the detection mechanism 50 is configured to detect the height of the roller gap 11 in real time to determine whether the material has been rolled to a preset thickness. The material being rolled includes at least an electrode sheet or a composite composed of multiple electrode sheets.

[0055] The roller pressing device proposed in this application is provided with a detection mechanism 50 on the upper roller mechanism 20 and / or the lower roller mechanism 30. The detection mechanism 50 can detect the height of the roller pressing gap 11 between the upper roller mechanism 20 and the lower roller mechanism 30 in real time, thereby accurately controlling the roller pressing thickness of the material and improving the roller pressing accuracy of the material.

[0056] Please see Figure 1 , Figure 3 and Figure 4As shown, in one embodiment, the upper pressure roller mechanism 20 includes a second drive member 21, two upper roller seats 22, and an upper pressure roller 23. The two upper roller seats 22 are vertically and flexibly mounted on the frame 10 at intervals along a first horizontal direction. The upper pressure roller 23 extends along the first horizontal direction, and the roller shaft of the upper pressure roller 23 is rotatably mounted on the two upper roller seats 22 at its two ends in the first horizontal direction. The frame 10 has a clearance notch 12 for avoiding the roller shaft of the upper pressure roller 23. The fixed end of the second drive member 21 is mounted on the first upper roller seat 22, and the driving end of the second drive member 21 is connected to the roller shaft of the upper pressure roller 23. The second drive member 21 is configured to drive the upper pressure roller 23 to rotate. The lower pressure roller mechanism 30 includes a third drive member 31, two upper roller seats 22, and an upper pressure roller 23. A lower roller seat 32 and a lower pressure roller 33 are fixedly mounted on the frame 10 at intervals along a first horizontal direction. Each lower roller seat 32 corresponds to an upper roller seat 22, and the lower roller seat 32 is located directly below the corresponding upper roller seat 22. The lower pressure roller 33 extends along the first horizontal direction, and the roller shaft of the lower pressure roller 33 is rotatably mounted on the two lower roller seats 32 at both ends of the first horizontal direction. The fixed end of the third driving member 31 is mounted on the first lower roller seat 32, and the driving end of the third driving member 31 is connected to the roller shaft of the lower pressure roller 33. The third driving member 31 is configured to drive the lower pressure roller 33 to rotate. A roller pressure gap 11 is formed between the upper pressure roller 23 and the lower pressure roller 33, and the rotation directions of the upper pressure roller 23 and the lower pressure roller 33 are the same.

[0057] Specifically, a guide assembly is provided between the upper roller seat 22 and the frame 10. The guide assembly improves the stability and reliability of the upper roller seat 22 in raising and lowering relative to the frame 10. The guide assembly includes a linear guide rail 13 and a slider 14. Preferably, the linear guide rail 13 is fixedly installed on the frame 10 in the vertical direction, and the slider 14 is slidably mounted on the linear guide rail 13 and fixedly connected to the upper roller seat 22.

[0058] Specifically, both the second drive unit 21 and the third drive unit 31 use servo motors.

[0059] As can be seen, by mounting two upper roller seats 22 at intervals on the frame 10 and rotatably mounting the two ends of the roller shaft of the upper pressure roller 23 on the two upper roller seats 22 respectively, and driving the upper pressure roller 23 to rotate through the second driving member 21, the upper pressure roller 23 is lifted and rotated relative to the frame 10, thus providing an upper pressure roller mechanism 20 with a simple structure and stable and reliable operation; by fixing two lower roller seats 32 at intervals on the frame 10 and rotatably mounting the two ends of the roller shaft of the lower pressure roller 33 on the two lower roller seats 32 respectively, and driving the lower pressure roller 33 to rotate through the third driving member 31, the lower pressure roller 33 is rotated relative to the frame 10, thus providing a lower pressure roller mechanism 30 with a simple structure and stable and reliable operation.

[0060] In one embodiment, the detection mechanism 50 includes two detection components 51, which are respectively disposed between a set of upper roller seats 22 and a corresponding lower roller seat 32. Each detection component 51 includes a dial indicator 510 and a bracket 511. The dial indicator 510 is fixedly mounted on the upper roller seat 22, and the bracket 511 is mounted on the lower roller seat 32 with adjustable height. A reference surface is horizontally provided on the bracket 511, and the measuring rod of the dial indicator 510 is vertically downward and abuts against the reference surface. The reference surface heights of the brackets 511 of the two detection components 51 are the same.

[0061] In one embodiment, the dial indicator 510 is fixedly mounted on the lower roller seat 32, and the bracket 511 is height-adjustably mounted on the upper roller seat 22. The measuring rod of the dial indicator 510 is vertically upward and abuts against the reference surface.

[0062] Specifically, the mounting end of the bracket 511 is provided with a threaded section, and a threaded hole is opened on the lower roller seat 32 or the upper roller seat 22. The bracket 511 is installed in the corresponding threaded hole through the threaded section, and the height of the bracket 511 is adjusted by the cooperation between the threaded section and the threaded hole.

[0063] As can be seen, by setting a detection component 51 between each set of upper roller seat 22 and the corresponding lower roller seat 32, two detection points at the same reference height are formed between the upper pressure roller 23 and the lower pressure roller 33, which improves the detection accuracy of the detection mechanism 50. The height detection of the roller gap by the cooperation of the dial indicator 510 and the bracket 511 has the advantages of high measurement accuracy, wide applicability, and high stability and reliability. At the same time, the height of the bracket 511 is adjustable, and the reference surface for detection can be adjusted as needed.

[0064] In one embodiment, a limiting component 60 is provided between the upper roller seat 22 and the corresponding lower roller seat 32. The limiting component 60 is configured to limit the downward stroke of the upper roller seat 22.

[0065] As can be seen, by setting a limiting component 60 between the upper roller seat 22 and the corresponding lower roller seat 32 to limit the downward stroke of the upper roller seat 22, the two ends of the upper pressure roller 22 can be limited during the material rolling process, thereby ensuring that the upper pressure roller 22 is in a horizontal state and further improving the rolling accuracy of the material.

[0066] In one embodiment, the limiting assembly 60 includes a base 61, a support member 62, an adjusting rod 63, an adjusting seat 64, and a locking member 65. The base 61 is fixedly installed on the lower roller seat 32, and a limiting groove 66 is formed on the base 61. The support member 62 is configured to support the upper roller seat 22. The bottom surface of the support member 62 is a wedge surface, and the bottom of the limiting groove 66 is an inclined surface that cooperates with the wedge surface. The support member 62 can be translatably installed in the limiting groove 66 along the inclined surface. The adjusting seat 64 is fixed on the lower roller seat 32. The adjusting rod 63 is rotatably inserted through the adjusting seat 64. The adjusting rod 63 is connected to the support member 62. The locking member 65 is installed on the adjusting seat 64. The locking member 65 is configured to lock or release the adjusting rod 63 relative to the adjusting seat 64. When the locking member 65 releases the adjusting rod 63, the adjusting rod 63 is rotated to drive the support member 62 to translate along the inclined plane. Then, through the cooperation of the wedge surface and the inclined plane, the support member 62 is driven to rise and fall.

[0067] Specifically, the adjusting seat 64 has a threaded hole, and the adjusting rod 63 has an external thread section. The adjusting rod 63 is installed in the threaded hole on the adjusting seat 64 through the external thread section. Rotating the adjusting rod 63 causes it to move horizontally through the cooperation between the external thread section and the threaded hole.

[0068] Specifically, the locking component 65 includes a locking block 650 and a locking bolt 651. The locking block 650 is fixedly mounted on the adjusting seat 64. The locking block 650 has a first locking part and a second locking part that are spaced apart and can be close to or far from each other. There is a channel between the first locking part and the second locking part for the adjusting rod 63 to pass through. The first locking part and the second locking part have corresponding threaded holes. The locking bolt 651 passes through the threaded holes of the first locking part and the second locking part. Rotating the locking bolt 651 in the forward direction makes the first locking part and the second locking part close to each other to hold the adjusting rod 63 tightly and fix it on the adjusting seat 64. Rotating the locking bolt 651 in the reverse direction makes the first locking part and the second locking part move away from each other to loosen the adjusting rod 63 relative to the adjusting seat 64.

[0069] Specifically, the operating end of the adjusting rod 63 is equipped with an adjusting head, and the adjusting head has an operating hole. A special tool is inserted into the operating hole to rotate the adjusting head, which in turn drives the adjusting rod 63 to rotate. The operation is convenient and labor-saving.

[0070] As can be seen, by cooperating the inclined wedge surface of the support member 62 with the inclined surface of the limiting groove 66, the translational movement of the support member 62 along the inclined surface is transformed into the lifting movement of the support member 62. The structure is simple and the operation is stable and reliable. By cooperating the adjusting rod 63 and the adjusting seat 64, the support member 62 is driven to translate along the inclined surface. The operation is convenient and labor-saving. The locking member 65 locks the adjusting rod 63 relative to the adjusting seat 64 to prevent the adjusting rod 63 from shifting when not in operation.

[0071] In one embodiment, the roller pressing device further includes a fourth driving member 70. The fixed end of the fourth driving member 70 is mounted on the lower roller seat 32, and the driving end of the fourth driving member 70 is connected to the upper roller seat 22 corresponding to the lower roller seat 32. The fourth driving member 70 is configured to drive the upper roller seat 22 to rise, so that the upper roller seat 22 is lifted away from the support member 62 at a preset height.

[0072] Specifically, the fourth driving component 70 is the first cylinder, which is vertically fixed on the lower roller seat 32. The piston rod of the first cylinder faces upward and is connected to the upper roller seat 22 corresponding to the lower roller seat 32.

[0073] When it is necessary to adjust the height of the support member 62, the two upper roller seats 22 are first lifted away from the support member 62 by the fourth drive member 70, and then the height of the support member 62 is adjusted by the adjusting rod 63.

[0074] As can be seen, by setting the fourth driving component 70, the upper roller seat 22 can be lifted away from the support component 62 without exerting downward pressure on the support component 62, which facilitates equipment maintenance or adjustment of the height of the support surface of the support component 62.

[0075] In one embodiment, pressure sensors 24 are installed on both upper roller seats 22. Two first drive members 40 are provided, and the drive ends of the two first drive members 40 are respectively connected to the two pressure sensors 24. The two pressure sensors 24 are configured to detect the pressure applied to the upper roller seat 22 by the corresponding first drive member 40.

[0076] Specifically, the first driving component 40 is the second cylinder, which is vertically fixed on the frame 10. The piston rod of the second cylinder faces downward and is connected to the corresponding pressure sensor 24.

[0077] It can be seen that by installing pressure sensors 24 on both upper roller seats 22, the pressure applied by the two first driving components 40 to the upper roller seats 22 is automatically detected, thereby controlling the pressure applied to the two upper roller seats 22 to be balanced, so that the pressure applied by the upper pressure roller 23 is uniform, which is beneficial to improving the rolling accuracy and rolling effect of the material.

[0078] In one embodiment, a heating element is provided on the upper pressure roller 23 and / or the lower pressure roller 33, and the heating element is configured to heat the upper pressure roller 23 and / or the lower pressure roller 33.

[0079] Specifically, the heating element is an electric heating rod or a ceramic heating element inserted into the upper pressure roller 23 and / or the lower pressure roller 33.

[0080] Specifically, a slip ring 71 is installed on the second upper roller seat 22 and / or the second lower roller seat 32. The wires and air pipes are introduced into the corresponding upper pressure roller 23 and / or lower pressure roller 33 through the slip ring 71. One side of the slip ring 71 is connected to the upper pressure roller 23 or the lower pressure roller 33, and the other side of the slip ring 71 is used to connect the air pipe and the power cord, so as to prevent the air pipe or the power cord from getting tangled during the rotation of the upper pressure roller 23 and the lower pressure roller 33.

[0081] As can be seen, by providing heating components on the upper pressure roller 23 and / or the lower pressure roller 33, the material is heated while being rolled. Heating the material facilitates the rolling of the material by the upper pressure roller 23 and the lower pressure roller 33, as well as the shaping of the material.

[0082] Please see Figure 1 and Figure 2 As shown, in one embodiment, the roller pressing device further includes a first conveying mechanism 72, which is arranged in the second horizontal direction of the gap. Figure 1 On the first side of the Y direction, the first conveying mechanism 72 is configured to convey material toward the roller gap 11, the first horizontal direction being perpendicular to the second horizontal direction.

[0083] Specifically, the first conveying mechanism 72 is a belt conveyor line.

[0084] It can be seen that by setting the first conveying mechanism 72, the material is automatically conveyed to the roller gap 11, which improves the work efficiency.

[0085] In one embodiment, the roller pressing device further includes a second conveying mechanism 73, which is disposed on the second side of the roller pressing gap 11 in the second horizontal direction. The second conveying mechanism 73 is configured to convey material toward the roller pressing gap 11. The first conveying mechanism 72 and the second conveying mechanism 73 convey the material in the same direction and at the same speed.

[0086] Specifically, the second conveying mechanism 73 is a belt conveyor line.

[0087] It can be seen that by setting up a second conveying mechanism 73, and configuring the second conveying mechanism 73 to convey the material in the same direction and at the same speed as the first conveying mechanism 72, the material can be repeatedly conveyed to the roller gap 11, thereby realizing multiple repeated roller pressing of the material and improving the roller pressing efficiency. In one embodiment, the first conveying mechanism 72 first drives the material to be conveyed along the first horizontal direction and passes through the roller gap 11 to perform a first roller pressing on the material. During this period, the thickness of the material is detected in real time by a detection mechanism. When the thickness of the material has not yet reached the predetermined thickness, the second conveying mechanism 73 then drives the material to be conveyed in the opposite direction of the first horizontal direction and passes through the roller gap 11 again to perform a second roller pressing on the material. The above actions are repeated until the thickness of the material reaches the predetermined thickness.

[0088] Please see Figures 1 to 4 As shown, the general working principle of the roller pressing device proposed in this application is as follows: First, the downward stroke of the upper roller 23 is adjusted by the limiting component 60 (that is, the roller pressing gap 11 between the upper roller 23 and the lower roller 33 is adjusted to a preset distance); then the first driving component 40 drives the upper roller 23 to descend a preset height; finally, the first conveying mechanism 72 receives the material to be roller pressed and conveys the received material to be roller pressed to the roller pressing gap 11. Through the rotational cooperation of the upper roller 23 and the lower roller 33, the material passing through the roller pressing gap 11 is roller pressed.

[0089] The roller pressing device proposed in this application has the following advantages:

[0090] 1) It can detect the height of the roller gap 11 between the upper roller mechanism 20 and the lower roller mechanism 30 in real time, thereby accurately controlling the roller thickness of the material and improving the roller accuracy of the material;

[0091] 2) The testing agency 50 has high measurement accuracy, wide applicability, and high stability and reliability;

[0092] 3) The limiting component 60 can limit both ends of the upper pressure roller 22 during the material rolling process, thereby ensuring that the upper pressure roller 22 is in a horizontal state and improving the rolling accuracy of the material;

[0093] 4) The limit component 60 has a simple structure, stable and reliable operation, and is convenient and labor-saving to operate;

[0094] 5) It has a pressure detection function, which controls the pressure applied to the two upper roller seats 22 to be balanced, so that the pressure applied by the upper pressure roller 23 is uniform, which is beneficial to improving the rolling accuracy of the material;

[0095] 6) The upper pressure roller 23 and the lower pressure roller 33 work together to have both rolling and heating functions.

[0096] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
