Description

Technical Field

[0001] The invention relates to the technical field of raw material dispersion, and in particular to a dispersion device for raw material processing. Background Art

[0002] In the process of producing products such as electronic adhesives or conductive adhesives, it is necessary to first disperse the slurry as the raw material or crush and disperse the cake as the raw material to obtain an intermediate, and then perform subsequent processing operations on the intermediate.

[0003] From the above, in the prior art, a dispersing device is generally used to disperse the slurry or to crush and disperse the cake. Specifically, the dispersing device includes two rollers arranged in parallel. Under the squeezing and friction of the two rollers, the raw materials can be fully dispersed. Since different production needs have different requirements for the dispersion degree of the intermediate obtained by dispersion, manufacturers usually have multiple dispersing devices. For different dispersing devices, the spacing between the two rollers is different, so that intermediates with different dispersion degrees can be dispersed accordingly. However, stocking multiple dispersing devices will lead to higher production costs.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] Based on the above, in the process of producing products such as electronic adhesives or conductive adhesives, it is necessary to first crush and / or disperse the slurry or cake as the raw material to obtain an intermediate, and then perform subsequent processing on the intermediate.

[0036] From the above, in the prior art, a dispersing device is generally used to disperse the slurry or to crush and disperse the cake. Specifically, the dispersing device includes two rollers arranged in parallel. Under the squeezing and friction of the two rollers, the raw materials can be fully dispersed. Since different production needs have different requirements for the dispersion degree of the intermediate obtained by dispersion, manufacturers usually have multiple dispersing devices. For different dispersing devices, the spacing between the two rollers is different, so that intermediates with different dispersion degrees can be dispersed accordingly. However, stocking multiple dispersing devices will lead to higher production costs. In addition, during the operation of the dispersing device, the bearings used to support the rotation of the rollers will increase their clearance due to factors such as vibration, which will cause the rollers to be unable to rotate stably, and then the raw materials cannot be fully dispersed.

[0037] To disperse the raw materials and solve the above problems, please refer to Figures 1 to 7 This embodiment provides a dispersing device for raw material processing, which includes a first roller 1 and a second roller 2 arranged in parallel. Under the extrusion and friction of the first roller 1 and the second roller 2, the raw material can be fully dispersed.

[0038] In addition to the first roller 1 and the second roller 2, in this embodiment, the dispersing device for raw material processing also includes a support seat 3 and a spacing adjustment mechanism 4, wherein the second roller 2 is rotatably connected to the support seat 3, and the spacing adjustment mechanism 4 is provided at both ends of the first roller 1, and the spacing adjustment mechanism 4 includes a first adjustment plate 41 and a drive module 42, and the end of the first roller 1 is rotatably connected to the first adjustment plate 41, and the first adjustment plate 41 is rotatably connected to the support seat 3 through the first rotating shaft 411, the axial direction of the first rotating shaft 411 is parallel to the axial direction of the first roller 1, and the first rotating shaft 411 is located on one side of the first roller 1 along its radial direction, and the driving module 42 is configured to drive the first adjustment plate 41 to rotate around the axis of the first rotating shaft 411.

[0039] That is, in this embodiment, along the radial direction of the second roller 2, the position of the second roller 2 remains stationary, and the spacing adjustment mechanism 4 can adjust the position of the first roller 1 relative to the second roller 2 along its radial direction by swinging the first adjustment plate 41 around the axis of the first rotating shaft 411, thereby adjusting the spacing between the first roller 1 and the second roller 2. Specifically, since the first rotating shaft 411 is arranged parallel to the first roller 1, when the driving module 42 drives the first adjustment plate 41 to rotate around the axis of the first rotating shaft 411, the first roller 1 can move with the first adjustment plate 41, thereby being able to adjust the spacing between the first roller 1 and the second roller 2.

[0040] In addition, the dispersion device for raw material processing also includes a clearance elimination mechanism 5, the clearance elimination mechanism 5 includes a second adjustment plate 51 and a first clearance elimination module 52, the first adjustment plate 41 is fixedly connected to the second adjustment plate 51, the end of the first roller 1 is rotatably connected to the second adjustment plate 51 through the first bearing 11, the first bearing 11 is a bearing structure for supporting the rotation of the first roller 1, and the first clearance elimination module 52 is configured to eliminate the clearance of the first bearing 11, thereby ensuring that the first roller 1 can rotate continuously and stably.

[0041] Based on the above, in this embodiment, along the radial direction of the second roller 2, the position of the second roller 2 remains stationary, and the end of the first roller 1 is provided with a first adjustment plate 41, and the driving module 42 can drive the first adjustment plate 41 to swing, so that the spacing between the first roller 1 and the second roller 2 can be adaptively adjusted according to production requirements, thereby controlling the dispersion degree of the dispersed intermediate. Since the dispersion device for raw material processing in this embodiment itself has the function of adjusting the spacing between the first roller 1 and the second roller 2, the manufacturer only needs to adjust the spacing between the first roller 1 and the second roller 2 when the production requirements change, without the need to reserve multiple dispersion devices, thereby reducing production costs. In addition, this embodiment can also eliminate the clearance of the first bearing 11 used to support the rotation of the first roller 1 through the clearance elimination mechanism 5, thereby ensuring that the first roller 1 can rotate continuously and stably without being affected by factors such as vibration, thereby ensuring that the raw materials can be fully dispersed.

[0042] It is worth noting that the second roller 2 is provided with first rollers 1 on both sides thereof in radial direction, that is, in this embodiment, the raw materials are dispersed twice by two first rollers 1, so as to further ensure that the raw materials can be fully dispersed. Moreover, in this embodiment, the two first rollers 1 are correspondingly provided with a spacing adjustment mechanism 4 and a clearance elimination mechanism 5, that is, for any first roller 1, a spacing adjustment mechanism 4 and a clearance elimination mechanism 5 are provided at both ends thereof, so that the spacing between any first roller 1 and the second roller 2 can be adjusted, and for any first roller 1, the clearance of the first bearing 11 for supporting its rotation can be eliminated.

[0043] Specifically, in this embodiment, the outer periphery of the second roller 2 is provided with a first gear 72 and a second gear 73, the outer periphery of one of the first rollers 1 is provided with a third gear 74, and the outer periphery of the other first roller 1 is provided with a fourth gear 75, the first gear 72 is meshed with the third gear 74, and the second gear 73 is meshed with the fourth gear 75. Moreover, in this embodiment, the dispersing device for raw material processing further includes a driving motor 71, and the driving motor 71 can drive the first roller 1 provided with the third gear 74 to rotate through a transmission belt 711. It is worth noting that in this embodiment In the embodiment, the third gear 74 is a small gear, the first gear 72 is a large gear, in addition, the second gear 73 is a small gear, and the fourth gear 75 is a large gear, so that a speed ratio relationship of 9:3:1 is formed between the first roller 1 sleeved with the third gear 74, the second roller 2 and the first roller 1 sleeved with the fourth gear 75, wherein the rotation speed of the first roller 1 sleeved with the fourth gear 75 is the slowest, the rotation speed of the second roller 2 is higher than the rotation speed of the first roller 1 sleeved with the fourth gear 75, and the rotation speed of the first roller 1 sleeved with the third gear 74 is the fastest.

[0044] It is understandable that in other optional embodiments, the driving motor 71 may also be configured to directly drive the second roller 2 or another first roller 1 to rotate, and this embodiment does not impose any specific limitation on this.

[0045] In addition, it can also be understood that the drive motor 71 can be selected as a stepper motor or a servo motor, etc., and this embodiment does not impose any specific limitation on this.

[0046] From above, Figure 4 and Figure 5 As shown, in this embodiment, the raw material in the form of agglomerates can be supplied between the second roller 2 and the first roller 1 provided with the fourth gear 75, so as to perform the first dispersion operation. Specifically, the speed ratio of the second roller 2 to the first roller 1 provided with the fourth gear 75 is 3:1, so a shear force can be formed between the second roller 2 and the first roller 1 provided with the fourth gear 75, and under the action of the shear force, the raw material in the form of agglomerates is dispersed for the first time. Afterwards, the raw material can be transported to the second roller 2 and the first roller 1 provided with the third gear 74, so as to perform the second dispersion operation. Specifically, the speed ratio of the second roller 2 to the first roller 1 provided with the third gear 74 is 3:9, so a shear force can also be formed between the second roller 2 and the first roller 1 provided with the third gear 74, and under the action of the shear force, the raw material is dispersed for the second time, so as to finally form an intermediate with a smaller particle size, and the raw material after completing the second dispersion operation is sent out.

[0047] Based on the above, the spacing between the second roller 2 and the two first rollers 1 is adjustable. Therefore, for the first roller 1 with the fourth gear 75, this embodiment can adjust the spacing between it and the second roller 2 to control the shear force between it and the second roller 2, thereby controlling the dispersion of the intermediate obtained after the first dispersion operation. For the first roller 1 with the third gear 74, this embodiment can adjust the spacing between it and the second roller 2 to control the shear force between it and the second roller 2, thereby controlling the dispersion of the intermediate obtained after the second dispersion operation. From the above, this embodiment can adjust the spacing between the first roller 1 and the second roller 2 to control the dispersion of the intermediate obtained by dispersion.

[0048] Based on the above, in the present embodiment, the driving module 42 is arranged on the side of the first roller 1 radially away from the first rotating shaft 411, and can apply a thrust to the first adjustment plate 41, so that the first adjustment plate 41 can rotate around the axis of the first rotating shaft 411. Specifically, in the present embodiment, the driving module 42 can apply a thrust to the first roller 1 toward the side close to the second roller 2, so that the first adjustment plate 41 can swing toward the side close to the second roller 2, thereby adjusting the distance between the first roller 1 and the second roller 2.

[0049] Among them, the driving module 42 includes a cam 421, a driving member 422 and a pressure member 423. The cam 421 is rotatably connected to the first adjustment plate 41 through the second rotating shaft 4211. The axial direction of the second rotating shaft 4211 is parallel to the axial direction of the first rotating shaft 411. The driving member 422 is installed on the first adjusting plate 41 and is configured to drive the cam 421 to rotate around the axis of the second rotating shaft 4211. The pressure member 423 is arranged on one side of the cam 421 along the radial direction of the second rotating shaft 4211 and abuts against the wheel surface of the cam 421. As the cam 421 rotates, the pressure member 423 abuts against various positions of the wheel surface of the cam 421 in turn. Since the wheel surface of the cam 421 is concave and convex, as the cam 421 rotates, the distance between the axis of the second rotating shaft 4211 and the pressure member 423 changes accordingly, so that the first adjusting plate 41 can drive the first roller 1 to swing, thereby adjusting the distance between the first roller 1 and the second roller 2.

[0050] From the above, the cam 421 and the first rotating shaft 411 are respectively located on both sides of the connection part between the first adjusting plate 41 and the first roller 1. This embodiment can control the rotation of the cam 421 according to the actual production requirements, so that the corresponding position on the cam 421 abuts against the pressure-bearing member 423, thereby adjusting the distance between the axis of the second rotating shaft 4211 and the pressure-bearing member 423, and then adjusting the distance between the first roller 1 and the second roller 2 to be equal to the preset value to meet the production requirements. It can be understood that when the distance between the pressure-bearing member 423 and the axis of the second rotating shaft 4211 decreases, the first adjusting plate 41 swings to the side away from the second roller 2, and the distance between the first roller 1 and the second roller 2 increases. When the distance between the pressure-bearing member 423 and the cam 421 increases, the first adjusting plate 41 swings to the side close to the second roller 2, and the distance between the first roller 1 and the second roller 2 decreases.

[0051] As shown above, when the pressure-bearing member 423 abuts against the bottom of the recessed portion of the cam 421, the distance between the axis of the second rotating shaft 4211 and the pressure-bearing member 423 is the smallest. At this time, the distance between the first roller 1 and the second roller 2 is the largest. When the cam 421 rotates so that the protruding portion of the cam 421 abuts against the pressure-bearing member 423, the pressure-bearing member 423 applies a thrust to the first adjustment plate 41 and swings the first adjustment plate 41 toward the side close to the second roller 2, thereby reducing the distance between the first roller 1 and the second roller 2. When the pressure-bearing member 423 abuts against the top of the protruding portion of the cam 421, that is, when the pressure-bearing member 423 abuts against the highest point of the protruding portion of the cam 421, the distance between the axis of the second rotating shaft 4211 and the pressure-bearing member 423 is the largest. At this time, the distance between the first roller 1 and the second roller 2 is the smallest.

[0052] Correspondingly, when the pressure member 423 abuts against a position on the cam 421 between the bottom of the recessed portion and the top of the protruding portion, the spacing between the first roller 1 and the second roller 2 is between the maximum spacing value and the minimum spacing value.

[0053] It is worth noting that, in the present embodiment, the two first rollers 1 are each provided with a spacing adjustment mechanism 4 , and the two spacing adjustment mechanisms 4 are symmetrically arranged, and the two spacing adjustment mechanisms 4 can adjust the positions of the two first rollers 1 respectively.

[0054] Based on the contents mentioned above, for any first roller 1, both ends thereof are provided with a spacing adjustment mechanism 4. In this embodiment, the spacing between the first roller 1 and the second roller 2 can be adjusted by two spacing adjustment mechanisms 4 respectively provided at both ends thereof. Specifically, for the two spacing adjustment mechanisms 4, the first adjustment plates 41 of the two spacing adjustment mechanisms 4 swing simultaneously and toward the same side, so as to adjust the spacing between the first roller 1 and the second roller 2.

[0055] It is also worth mentioning that in this embodiment, the driving member 422 is a servo motor, so as to accurately control the rotation angle of the cam 421. Of course, in other optional embodiments, the driving member 422 can also be other driving structures such as a stepping motor or a rotary cylinder, and this embodiment does not impose specific restrictions on this.

[0056] Furthermore, the pressure-bearing member 423 is a roller, and the wheel surface of the roller abuts against the wheel surface of the cam 421 , thereby ensuring that the cam 421 can rotate smoothly, that is, this embodiment can prevent the pressure-bearing member 423 from blocking the rotation of the cam 421 .

[0057] For further information, see Figures 1 to 3 , and combined with Figure 6 The first clearance eliminating module 52 includes a first tension spring 521, one end of the first tension spring 521 is fixedly connected to the side of the second adjustment plate 51 away from the first rotating shaft 411 along the radial direction of the first bearing 11, and the other end of the first tension spring 521 is fixedly connected to the support seat 3. Specifically, the first clearance eliminating module 52 also includes a first mounting column 522, the first mounting column 522 is fixedly connected to the support seat 3, the other end of the first tension spring 521 is fixedly connected to the first mounting column 522, and the second adjustment plate 51 is fixedly connected to the first adjustment plate 41 along the side of the first bearing 11 away from the first tension spring 521. The first tension spring 521 can apply a first tension to the second adjustment plate 51, and the directions of the first tension and the thrust are opposite. Based on the principle of lever, under the action of the first tension, the second adjustment plate 51 can apply a pressure F1 to the first bearing 11, thereby eliminating the clearance of the first bearing 11, thereby ensuring that the first roller 1 can rotate continuously and stably without being affected by factors such as vibration.

[0058] In addition, since the second adjustment plate 51 is fixedly connected to the first adjustment plate 41 at one side away from the first tension spring 521 along the radial direction of the first bearing 11, when the cam 421 rotates to make the protruding part of the cam 421 abut against the pressure-bearing piece 423 and the first adjustment plate 41 swings toward the side close to the second roller 2, the second adjustment plate 51 can swing together with the first adjustment plate 41. At the same time, the first tension force applied to the second adjustment plate 51 by the first tension spring 521 increases. When the cam 421 rotates and makes the part with a smaller outer diameter on the cam 421 face the pressure-bearing piece 423, under the action of the first tension spring 521, the second adjustment plate 51 The adjustment plate 51 drives the first adjustment plate 41 to swing toward the side away from the second roller 2, so that the distance between the axis of the second rotating shaft 4211 and the pressure-bearing member 423 can be reduced. When the distance between the axis of the second rotating shaft 4211 and the pressure-bearing member 423 is reduced, the distance between the first roller 1 and the second roller 2 increases. When the cam 421 rotates to the point where the pressure-bearing member 423 and the bottom of the recessed portion of the cam 421 are directly opposite, under the action of the first tension spring 521, the pressure-bearing member 423 abuts against the bottom of the recessed portion of the cam 421, and the first adjustment plate 41 can be restored and maintained at the position where the distance between the first roller 1 and the second roller 2 is maximized.

[0059] Correspondingly, when the cam 421 rotates and makes the part with larger outer diameter on the cam 421 face the pressure-bearing part 423, under the pushing action of the pressure-bearing part 423, the distance between the axis of the second rotating shaft 4211 and the pressure-bearing part 423 increases, and the first adjustment plate 41 drives the second adjustment plate 51 to swing toward the side close to the second roller 2, so that the distance between the first roller 1 and the second roller 2 can be reduced. When the cam 421 rotates to the point where the pressure-bearing part 423 abuts against the top of the protruding part of the cam 421, the first adjustment plate 41 can swing to the position where the distance between the first roller 1 and the second roller 2 is minimized.

[0060] As described above, in this embodiment, the first adjustment plate 41 and the second adjustment plate 51 are both fixedly connected to the first rotating shaft 411, and the first rotating shaft 411 is rotatably connected to the support seat 3. When the first adjustment plate 41 swings, the second adjustment plate 51 swings therewith. When the second adjustment plate 51 swings toward the side away from the second roller 2 due to the first tension spring 521, the first adjustment plate 41 also rotates therewith.

[0061] That is, when the cam 421 rotates and makes the part with larger outer diameter on the cam 421 face the pressure-bearing part 423, under the pushing action of the pressure-bearing part 423, the distance between the axis of the second rotating shaft 4211 and the pressure-bearing part 423 increases, and the first adjusting plate 41 drives the second adjusting plate 51 to rotate around the axis of the first rotating shaft 411 and swing toward the side close to the second roller 2, so that the distance between the first roller 1 and the second roller 2 can be reduced. At the same time, the first tension spring 521 undergoes elastic deformation, so that the first tension force applied by the first tension spring 521 to the second adjusting plate 51 increases. When the cam 421 rotates until the pressure-bearing part 423 abuts against the top of the protruding part of the cam 421, the first adjusting plate 41 can swing to the position where the distance between the first roller 1 and the second roller 2 is minimized.

[0062] When the cam 421 rotates and makes the part with smaller outer diameter on the cam 421 face the pressure-bearing part 423, under the action of the first tension spring 521, the second adjustment plate 51 drives the first adjustment plate 41 to rotate around the axis of the first rotating shaft 411 and swing toward the side away from the second roller 2, so that the cam 421 remains in contact with the pressure-bearing part 423 and the distance between the axis of the second rotating shaft 4211 and the pressure-bearing part 423 is reduced. When the distance between the axis of the second rotating shaft 4211 and the pressure-bearing part 423 is reduced, the distance between the first roller 1 and the second roller 2 increases. When the cam 421 rotates until the pressure-bearing part 423 faces the bottom of the recessed part of the cam 421, under the action of the first tension spring 521, the pressure-bearing part 423 abuts against the bottom of the recessed part of the cam 421, and the first adjustment plate 41 can be restored and maintained at the position where the distance between the first roller 1 and the second roller 2 is the largest.

[0063] Furthermore, the driving module 42 also includes a pressure sensor 424, which is configured to detect the pressure applied by the cam 421 to the pressure-bearing member 423, so as to detect the distance between the first roller 1 and the second roller 2. Specifically, the dispersion device for raw material processing also includes a control module (not shown in the figure), which is electrically connected to the pressure sensor 424. The control module can receive the detection result of the pressure sensor 424 and perform calculation and analysis on the detection result, so as to detect the distance between the first roller 1 and the second roller 2.

[0064] Based on the above, during the dispersion operation, since the raw material can apply pressure to the first roller 1, and the pressure can be transmitted to the cam 421 and then to the pressure-bearing member 423 via the cam 421, the present embodiment can detect the pressure applied by the cam 421 to the pressure-bearing member 423 in real time during the dispersion operation through the pressure sensor 424, and thereby determine whether the distance between the first roller 1 and the second roller 2 is equal to a preset value; if the distance between the first roller 1 and the second roller 2 is not equal to the preset value, the distance between the first roller 1 and the second roller 2 is readjusted.

[0065] From the above, in this embodiment, the highest point of the wheel surface of the cam 421 abuts against the pressure member 423 as the initial position of the first roller 1. At this time, the wheel surface of the first roller 1 is in contact with and pressed against the wheel surface of the second roller 2. In this embodiment, the pressure sensor 424 can detect whether the first roller 1 is in the initial position. During the dispersion operation, when it is necessary to readjust the distance between the first roller 1 and the second roller 2, the driving member 422 controls the cam 421 to rotate until the first roller 1 is reset to the initial position. Thereafter, based on the initial position, the driving member 422 drives the cam 421 to rotate a preset angle, so that the distance between the first roller 1 and the second roller 2 is equal to the preset value.

[0066] It is worth noting that, in the present embodiment, the two first rollers 1 are each provided with a corresponding clearance eliminating mechanism 5 , and the two clearance eliminating mechanisms 5 are symmetrically arranged, and the two clearance eliminating mechanisms 5 can respectively eliminate the clearance of the first bearings 11 on the two first rollers 1 .

[0067] In addition, the dispersion device for raw material processing also includes a mounting plate 6, which is sleeved on the outer periphery of the two first rotating shafts 411 and is located between the second adjustment plate 51 and the first adjustment plate 41. The first rotating shaft 411 can rotate relative to the mounting plate 6, and the mounting plate 6 is fixedly connected to the support seat 3, thereby increasing the structural strength of the dispersion device for raw material processing.

[0068] In addition to the second adjustment plate 51 and the first clearance eliminating module 52, the clearance eliminating mechanism 5 also includes a third adjustment plate 53 and a second clearance eliminating module 54. The third adjustment plate 53 and the second clearance eliminating module 54 are correspondingly arranged at both ends of the second roller 2. The third adjustment plate 53 is fixedly connected to the support seat 3. The end of the second roller 2 is rotatably connected to the third adjustment plate 53 through the second bearing 21. The second clearance eliminating module 54 is configured to eliminate the clearance of the second bearing 21, thereby ensuring that the second roller 2 can rotate continuously and stably without being affected by factors such as vibration, thereby further ensuring that the raw materials can be fully dispersed.

[0069] See also Figures 1 to 3 , and combined with Figure 7The second clearance eliminating module 54 includes a second tension spring 541, one end of the second tension spring 541 is fixedly connected to one side of the third adjusting plate 53 along the radial direction of the second bearing 21, and the other side of the third adjusting plate 53 along the radial direction of the second bearing 21 is fixedly connected to the support seat 3. Specifically, the third adjusting plate 53 is fixedly connected to the mounting plate 6 along the other side of the radial direction of the second bearing 21. In addition, the other end of the second tension spring 541 is fixedly connected to the support seat 3. Specifically, the second clearance eliminating module 54 also includes a second mounting column 542, the second mounting column 542 is fixedly connected to the support seat 3, and the other end of the second tension spring 541 is fixedly connected to the second mounting column 542. The second tension spring 541 can apply a second tension to the third adjusting plate 53 in a direction perpendicular to the axial direction of the second roller 2. Based on the lever principle, under the action of the second tension, the third adjusting plate 53 can apply a pressure F2 to the second bearing 21, thereby eliminating the clearance of the second bearing 21, thereby ensuring that the second roller 2 can rotate continuously and stably without being affected by factors such as vibration.

[0070] It can be understood that the present embodiment does not impose any specific limitation on the direction of the second pulling force. Specifically, the second mounting column 542 can be disposed close to any one of the two second adjustment plates 51 , and the present embodiment does not impose any specific limitation on this.

[0071] Also, see Figures 1 to 3 , and combined with Figure 6 It should also be noted that a bearing structure is also provided between the first adjustment plate 41 and the first roller 1. Specifically, the first roller 1 is rotatably connected to the first adjustment plate 41 through the third bearing 12. Based on the above-mentioned contents, the pressure-bearing member 423 can apply a thrust to the first adjustment plate 41. Based on the principle of lever, under the thrust applied by the pressure-bearing member 423 to the first adjustment plate 41, the first adjustment plate 41 can apply a pressure F3 to the third bearing 12, thereby eliminating the clearance of the third bearing 12. The position where the first adjustment plate 41 applies pressure to the third bearing 12 and the position where the second adjustment plate 51 applies pressure to the first bearing 11 are respectively located on both sides of the first roller 1 along its radial direction, that is, the directions of F1 and F3 are opposite, thereby further ensuring that the first roller 1 can rotate continuously and stably without being affected by factors such as vibration.
