[0036] The roller body 30 is installed in the two mounting grooves 111 respectively at two ends thereof;

[0037] The first fastener 50 is connected to the edge of the mounting groove 111 of the seat body 11 near the connecting plate 13, and the second fastener 70 is connected to the edge of the mounting groove 111 of the seat body 11 away from the connecting plate 13, both of which are pressed against the two ends of the roller body 30, the first fastener 50 is provided with a first connecting hole 51 and a first adjusting hole 53, the first adjusting hole 53 is vertically arranged, the second fastener 70 is provided with a second connecting hole 71 and a second adjusting hole 73, the second adjusting hole 73 is horizontally arranged, the first adjusting hole 53 and the second adjusting hole 73 are respectively used for vertical adjustment of the two ends of the roller body 30, and the seat body 11 is provided with a third adjusting hole 113 horizontally arranged and communicating with the mounting groove 111 away from the connecting plate 13, which is used for horizontal adjustment of the other end of the roller body 30.

[0038] Firstly, the design of the mounting seat 10 is one of the cores of the application. The mounting seat 10 is composed of a seat body 11 and a connecting plate 13, and the two parts are connected to each other. The connecting plate 13 is used for connecting a frame body or a mounting plate, and one end of the seat body 11 is connected to the connecting plate 13. Two mounting grooves 111 are arranged in the structure of the seat body 11, and the two mounting grooves 111 are located at opposite sides of the seat body 11.

[0039] Next is the roller body 30, two ends of which are respectively installed in the two mounting grooves 111 mentioned above. Such a design ensures the stability and reliability of the roller body 30.

[0040] In order to further enhance the adjustment ability of the roller, the first fastener 50 and the second fastener 70 are designed. The first fastener 50 is connected to the edge of the mounting groove 111 of the seat body 11 near the connecting plate 13, and the second fastener 70 is connected to the edge of the mounting groove 111 of the seat body 11 away from the connecting plate 13. Both of the fasteners are pressed against the two ends of the roller body 30 to ensure its stability. The first fastener 50 is provided with a first connecting hole 51 and a first adjusting hole 53, and the first adjusting hole 53 is vertically arranged. Similarly, the second fastener 70 is also provided with a second connecting hole 71 and a second adjusting hole 73, and the second adjusting hole 73 is horizontally arranged. The first adjusting hole 53 and the second adjusting hole 73 are arranged to facilitate the vertical adjustment of the two ends of the roller body 30. In addition, the seat body 11 is also provided with a third adjusting hole 113 horizontally arranged and communicating with the mounting groove 111 away from the connecting plate 13, which is used for horizontal adjustment of the other end of the roller body 30.

[0041] The application achieves accurate adjustment of both ends of the roller body 30 by setting the first fastener 50 and the second fastener 70. The first fastener 50 is connected to the edge of the mounting groove 111 on the side of the seat body 11 close to the connecting plate 13, connected to the seat body 11 through the first connecting hole 51, and the first adjusting hole 53 is used for abutting and adjusting in the vertical direction of one end of the roller body 30. The second fastener 70 is connected to the edge of the mounting groove 111 on the side of the seat body 11 away from the connecting plate 13, connected to the seat body 11 through the second connecting hole 71, and the second adjusting hole 73 is used for abutting and adjusting in the vertical direction of the other end of the roller body 30. The third adjusting hole 113 is opened in the horizontal direction of the seat body 11, and the other end of the roller body 30 can be adjusted in the horizontal direction through the hole. Through the specific design of the adjusting mechanism, the distance and angle between the over-rollers can be conveniently adjusted.

[0042] In order to realize the accurate installation of the over-roller, the application also adopts the screw pressing fixation mode. Through the fixation of the first connecting hole 51 and the second connecting hole 71, and then using the top stone fine adjustment, the adjustment of the first adjusting hole 53, the second adjusting hole 73 and the third adjusting hole 113 can be carried out to ensure that the over-roller distance meets the process requirements. Through the setting of the first fastener 50, the second fastener 70 and the third adjusting hole 113 on the seat body 11, the position and angle of the over-roller can be quickly and accurately adjusted during the installation of the over-roller.

[0043] In addition, the application also specially designs an adjusting mechanism, which includes an adjustable screw and a top stone for accurately adjusting the distance. Through screw pressing fixation and top stone fine adjustment, it can be ensured that the over-roller distance meets the process requirements.

[0044] In the actual installation process, first, the over-roller is placed on the mounting seat 10 according to the preset position, then the position is finely corrected by adjusting the screw and the top stone, and finally the screw is tightened to complete the installation. Such installation steps ensure the stability and accuracy of the over-roller, meeting the process requirements.

[0045] Optionally, due to the structural design of the mounting seat 10 and the roller body 30, the over-roller has high stability and reliability during use. Secondly, through the design of the adjusting holes of the first fastener 50 and the second fastener 70, the roller body 30 can be finely adjusted in the vertical and horizontal directions, thereby meeting the accurate requirements under different process conditions. In addition, the setting of the adjusting mechanism makes the installation and adjustment process of the over-roller more convenient and fast, greatly improving the production efficiency.

[0046] In the manufacturing process, the over-roller of the application also performs well. Due to its simple structure and easy processing, the production cost is effectively controlled. At the same time, the stability and adjustment capacity of the over-roller also make it have high durability and reliability in long-term use, reduce the frequency of maintenance and replacement, and further reduce the production cost.

[0047] In terms of maintenance, the over roller of the present application also has obvious advantages. Due to its reasonable structure design, daily maintenance is simple and easy. By adjusting the adjusting holes on the first fastener 50 and the second fastener 70, the over roller can be easily corrected and adjusted to ensure that it is always in the best working condition. In addition, due to the durability and reliability of the over roller, its maintenance cycle is relatively long, further reducing the maintenance cost.

[0048] Further, the first adjusting hole 53 is arranged opposite to the axis of the roller body 30;

[0049] And / or, the second adjusting hole 73 is arranged opposite to the axis of the roller body 30.

[0050] Further, in order to ensure the accurate alignment of the adjusting hole with the roller body 30, the first adjusting hole 53 is designed to be completely opposite to the axis of the roller body 30, so as to ensure that the position of the adjusting hole is completely consistent with the central axis of the roller body 30. This design can effectively improve the accuracy and reliability of the adjustment, ensuring that the equipment can be more stable and efficient during operation.

[0051] At the same time, in order to further improve the flexibility and applicability of the adjustment, the second adjusting hole 73 is also arranged to be completely opposite to the axis of the roller body 30. This double opposite design not only meets the adjustment needs under different working conditions, but also provides more adjustment options, so that the equipment can be more flexible when facing various complex situations, thereby improving the overall work efficiency and service life of the equipment.

[0052] In the specific embodiment, the solid-state battery positive and negative electrode material dry method over roller of the present application further comprises one or more positioning pins, which cooperate with the adjusting holes of the first fastener 50 and the second fastener 70 to ensure the accurate position of the over roller during adjustment. The setting of the positioning pin helps to prevent the position deviation of the over roller caused by vibration or external force during production, thereby ensuring the stability of the production process and the consistency of the product quality.

[0053] In addition, in order to further improve the adjustment accuracy and operation convenience of the over roller, the present application also provides an adjusting device with scale marks. By setting scale marks around the adjusting hole, the operator can intuitively read the adjustment position, thereby realizing quick and accurate fine adjustment. This design not only improves the work efficiency, but also reduces the production delay and material waste caused by improper adjustment.

[0054] Further, the number of third adjusting holes 113 is two, and the two third adjusting holes 113 are respectively arranged on the opposite sides of the seat body 11 in the horizontal direction, and both communicate with the installation groove 111.

[0055] The third adjustment hole 113 is two in number, which are respectively arranged on the opposite sides of the seat body 11 in the horizontal direction and are both communicated with the mounting groove 111. This design enables the third adjustment hole 113 to be effectively connected with the mounting groove 111, ensuring the realization of its function. Specifically, the third adjustment hole 113 located on the two sides of the seat body 11 in the horizontal direction can adjust the end of the roller body 30 in the mounting groove 111 through the top stone. In this way, the end of the roller body 30 can be pressed to change its position, achieving the effect of adjusting the horizontal offset angle of the roller body 30. This adjustment mechanism not only improves the accuracy of the device, but also enhances the flexibility of its operation, so that the user can make detailed adjustments according to actual needs to ensure the normal operation of the device and maximize the production efficiency.

[0056] In order to further enhance the adjustment function of the roller, the fourth adjustment hole 1153 is also designed in the present application. The fourth adjustment hole 1153 is also two in number, which are respectively arranged on the opposite sides of the seat body 11 in the vertical direction and form an intersection with the third adjustment hole 113. This intersection design enables the fourth adjustment hole 1153 to work together with the third adjustment hole 113 to realize more complex adjustment requirements. Specifically, the vertical position of the roller body 30 can be finely adjusted through the fourth adjustment hole 1153, so as to further optimize the installation accuracy of the roller body 30 while ensuring the stability of the horizontal position of the roller body 30.

[0057] In addition, in order to ensure the stability and reliability of the roller in long-term use, the anti-loosening structure is specially designed in the present application. The structure includes one or more elastic elements arranged between the fastener and the seat body 11. After the fastener is tightened, the elastic element can provide continuous pressure to prevent the fastener from loosening due to vibration or long-term use. This design not only improves the service life of the roller, but also reduces maintenance costs and downtime, thereby bringing greater economic benefits to the user.

[0058] Further, the seat body 11 includes a first mounting portion 11a, a second mounting portion 11b, and a connecting portion 11c, the two ends of the connecting portion 11c are respectively connected to the first mounting portion 11a and the second mounting portion 11b, the first mounting portion 11a is connected to the connecting plate 13, the first mounting portion 11a is provided with a mounting groove 111, the second mounting portion 11b is provided with another mounting groove 111, the first fastener 50 is connected to the first mounting portion 11a, and the second fastener 70 is connected to the second mounting portion 11b.

[0059] The seat body 11 is composed of three main parts, namely the first mounting part 11a, the second mounting part 11b and the connecting part 11c. The two ends of the connecting part 11c are closely connected with the first mounting part 11a and the second mounting part 11b respectively, ensuring the stability and firmness of the overall structure. The first mounting part 11a is connected with other components through the connecting plate 13 to enhance the overall connection strength. In order to further improve the reliability of the connection, the first mounting part 11a is specially provided with a mounting groove 111 to facilitate the installation and fixation of other components. Similarly, the second mounting part 11b is also provided with another mounting groove 111 to adapt to different installation requirements and improve the overall adaptability. In order to ensure the stability of the seat body 11, the first fastener 50 is designed to connect the first mounting part 11a, which can effectively prevent the first mounting part 11a from loosening or falling off during use. Similarly, the second fastener 70 is also designed to connect the second mounting part 11b, which can ensure that the second mounting part 11b remains stable during use and will not loosen or fall off. Overall, this design makes the seat body 11 more structurally stable, capable of bearing greater loads, while also improving the convenience of installation and disassembly.

[0060] In the specific embodiment, the manufacturing material of the seat body 11 is preferably a high-strength metal material such as aluminum alloy or stainless steel to ensure sufficient mechanical strength and durability. During manufacturing, precise numerical control machining technology can be used to ensure accurate dimensions and smooth surfaces of the various parts of the seat body 11, thereby reducing wear and tear due to friction and abrasion during use.

[0061] In order to further improve the performance of the seat body 11, the surface of the connecting part 11c can be treated with special processes such as anodizing or plating to enhance its corrosion resistance and wear resistance. In addition, the connection between the connecting part 11c and the first mounting part 11a and the second mounting part 11b can be designed as a stepped or beveled shape to increase the contact area and improve the stability of the connection.

[0065] The screw is arranged in the waist-shaped hole 1111 and can be moved, so that the relative position of the second mounting part 11b and the connecting part 11c is changed, and the relative height of the second mounting part 11b and the connecting part 11c is changed due to the fact that the waist-shaped hole 1111 is arranged in the vertical direction, so that the height of the end of the roller body 30 connected with the second mounting part 11b is changed.

[0066] In another embodiment of the present application, the adjusting piece 115 further comprises one or more horizontal adjusting holes, and the horizontal adjusting holes are arranged in the horizontal direction. The horizontal adjusting hole can be used for adjusting the horizontal distance between the connecting part 11c and the second mounting part 11b. By inserting an appropriate adjusting screw or bolt into the horizontal adjusting hole and tightening or loosening, the horizontal position of the connecting part 11c relative to the second mounting part 11b can be adjusted.
