[0001] This utility model belongs to the field of papermaking machine technology, and in particular relates to a guide roller for a papermaking machine. Background Technology

[0002] A paper machine is a collective term for a complete set of equipment that links different parts of the pulp to form a paper web. It includes main components such as the headbox, wire section, press section, dryer section, calender, winding machine, and drive section, as well as auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery. Guide rollers are an important component of a paper machine, guiding the material. However, most guide rollers used in traditional paper machines are of a fixed structure, which cannot adaptively adjust the limiting distance of the guide rollers according to the size of the material to be guided. As a result, when encountering materials of larger or smaller sizes, it is necessary to replace them with guide rollers of different sizes to guide the material accurately, which greatly reduces the effectiveness of the guide rollers.

Each set of push plates has a strip-shaped fixing hole. Push frames are inserted into the upper and lower sets of T-shaped uprights. Each set of push frames has auxiliary shifting frames fixed at both ends that cooperate with the strip-shaped fixing holes. Reinforcing screws penetrating the push frames are fixed on the opposite front sides of the fixed side plates. Each set of reinforcing screws is threaded with two sets of locking nuts, and the opposite sides of the locking nuts are attached to the push frames.

[0006] Preferably, an L-shaped side frame is fixed on one side of the upper and lower auxiliary moving frames that are close to each other, and one end of the L-shaped side frame passes through the fixed side plate and moves outward.

[0007] Preferably, the auxiliary frame has an overall U-shaped structure, and one end of the auxiliary frame that is located in the strip-shaped fixing hole has a rod-shaped structure.

[0008] Preferably, there is a gap between the auxiliary seat and the protruding end of the T-shaped stand, and there is a gap between the fixed side plate and the sliding side plate.

[0009] Preferably, the contact section between the T-shaped support and the auxiliary seat has a square plate-like structure.

[0010] Preferably, square grooves are provided at both ends of the guide roller body, and screw holes communicating with the square grooves are provided on both sides of the top of the guide roller body.

[0021] Example: A guide roller for a paper machine includes a guide roller body 1 that is connected to a preset mounting shaft on the paper machine. The guide roller body 1 has fixed side plates 2 symmetrically fixed on its left and right sides. The guide roller body 1 is used to guide the papermaking material. Each set of fixed side plates 2 has T-shaped uprights 4 symmetrically fixed vertically. The fixed side plates 2 and T-shaped uprights 4 are equipped with auxiliary adjustment components that cooperate with the guide roller body 1. The auxiliary adjustment components include sliding side plates 3 symmetrically slidably mounted on the guide roller body 1 in the left-right direction and located inside the fixed side plates 2. The sides of the sliding side plates 3 that are far apart from each other are vertically aligned. The push plate 6 is rotatably mounted. Each set of T-shaped uprights 4 is slidably mounted with an auxiliary seat 5, and one end of the push plate 6 is rotatably mounted on the auxiliary seat 5. Each set of push plates 6 is provided with a strip-shaped fixing hole 7. Push frames 8 are inserted into the upper and lower sets of T-shaped uprights 4. Each set of push frames 8 is fixed with an auxiliary moving frame 9 that works with the strip-shaped fixing hole 7 at both ends. The front of the fixed side plates 2 that are far apart from each other is fixed with a reinforcing screw 11 that passes through the push frame 8. Each set of reinforcing screw 11 is threaded with two sets of locking nuts 12. The side of the locking nuts 12 that is close to each other is attached to the push frame 8.

[0022] Specifically, this utility model, by setting up an auxiliary adjustment component, utilizes a push plate 6, an auxiliary seat 5, a strip-shaped fixing hole 7, an auxiliary shifting frame 9, a push frame 8, a reinforcing screw 11, and a locking nut 12 to autonomously adjust the distance between the two sets of sliding side plates 3. This allows for adaptive adjustment of the limiting distance of the guide roller body 1 to accommodate papermaking materials of different sizes. Consequently, it assists the guide roller body 1 in stably guiding papermaking materials of different sizes, avoiding the need to replace the guide roller body 1 with a different size when encountering papermaking materials of larger or smaller sizes for precise guidance, thus improving the applicability of the guide roller body 1.

[0023] An L-shaped side frame 10 is fixed on one side of the upper and lower auxiliary moving frames 9 that are close to each other. One end of the L-shaped side frame 10 passes through the fixed side plate 2 and moves outward.

[0024] Specifically, the design of the L-shaped side frame 10 can slide and limit the auxiliary moving frame 9 and provide synchronous support, thereby improving the stability of the auxiliary moving frame 9 during movement and preventing it from tilting downwards.

[0025] The auxiliary moving frame 9 has an overall U-shaped structure, and the end of the auxiliary moving frame 9 that is located in the strip-shaped fixing hole 7 has a rod-shaped structure.

[0026] Specifically, the shape of the auxiliary transfer frame 9 is defined to ensure stable movement of the push plate 6 and avoid obstruction.

[0027] There is a gap between the auxiliary seat 5 and the protruding end of the T-shaped stand 4, and there is a gap between the fixed side plate 2 and the sliding side plate 3.

[0028] Specifically, the spacing is designed to allow the sliding side plates 3 to have a certain outward displacement distance, which facilitates better adjustment of the spacing between the sliding side plates 3, so as to adapt to more papermaking materials of various sizes, and further improves the overall applicability of the guide roller body 1.

[0029] The contact section between the T-shaped support 4 and the auxiliary seat 5 has a square plate-like structure.

[0030] Specifically, the shape and position of the contact section between the T-shaped support 4 and the auxiliary seat 5 are defined to allow for sliding and limiting of the auxiliary seat 5, thereby improving the stability of the movement of the auxiliary seat 5 and preventing rotation.

[0031] Square grooves 13 are provided at both ends of the guide roller body 1, and screw holes 14 communicating with the square grooves 13 are provided on both sides of the top of the guide roller body 1.

[0032] Specifically, the design of the square groove 13 and the docking screw hole 14 allows the guide roller body 1 to be stably docked with the preset mounting shaft on the paper machine.

[0033] In use: When it is necessary to adjust the limiting distance between the guide roller body 1 and the paper material, the user should first rotate the locking nut 12 to both ends of the reinforcing screw 11, so that the pusher 8 is in a movable state, thereby releasing the locking state of the sliding side plate 3. At this time, the user can move the position of the sliding side plate 3 according to the size of the paper material. At the same time, the moving sliding side plate 3 will change the position of the pusher 6. With the cooperation of the strip fixing hole 7, the positions of the auxiliary moving frame 9 and the pusher 8 can be changed synchronously until the sliding side plate 3 is moved to the appropriate position. When the pusher is positioned correctly, the user can rotate the locking nut 12 again to make the two adjacent sets of locking nuts 12 fit back onto the pusher 8, thereby repositioning the moved pusher 8 and synchronously limiting the moved sliding side plate 3. At this time, the guide roller body 1 with adjustable limiting distance can help guide paper materials of different sizes stably, avoiding the need to replace the guide roller body 1 with a different size when encountering paper materials of larger or smaller sizes, thus improving the applicability of the guide roller body 1.

[0034] In summary, this paper machine guide roller, by setting an auxiliary adjustment component, can autonomously adjust the distance between the two sets of sliding side plates 3, thereby adaptively adjusting the limiting distance of the guide roller body 1 to adapt to paper materials of different sizes, thus assisting the guide roller body 1 in stably guiding paper materials of different sizes.

[0035] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
