Detailed implementation manners

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1-5As shown in the figure, the present utility model provides a fourdrinier paper machine, comprising: a machine body 1, and an adjusting assembly 2 fixedly connected to the top of the machine body 1; the adjusting assembly 2, which includes a storage tank 201 fixedly connected to the top of the machine body 1. A discharge hole 218 is provided at the inner bottom of the storage tank 201. A mounting frame 202 is fixedly connected to the outer surface of one side of the storage tank 201. A motor 203 is fixedly connected to the outer surface of the mounting frame 202. The output end of the motor 203 rotatably penetrates the outer surface of the mounting frame 202. The output end of the motor 203 is fixedly connected to a rotating rod 204. A first pulley 206 is fixedly connected to the outer surface of the rotating rod 204. A baffle 212 is arranged at the bottom of the storage tank 201. A connecting block 211 is fixedly connected to the bottom of the baffle 212. A threaded sleeve 210 is fixedly connected to the rear surface of the connecting block 211. A threaded rod 209 is threadedly and rotatably connected to the inner surface of the threaded sleeve 210. A second pulley 207 is fixedly connected to the outer surface of the threaded rod 209. A mounting plate 208 is fixedly connected to the rear surface of the storage tank 201. The inner surface of the mounting plate 208 is rotatably connected to the outer surface of the threaded rod 209. A limiting block 216 is fixedly connected to the outer surface of the threaded rod 209 near the rear surface. The outer surface of the limiting block 216 is rotatably connected to the inner surface of the mounting plate 208. Transmission belts 205 are arranged on the inner sides of the first pulley 206 and the second pulley 207. The first pulley 206 and the second pulley 207 are drivingly connected through the transmission belt 205. A rectangular groove is provided at the bottom of the storage tank 201. The baffle 212 is located inside the rectangular groove, and the outer surface of the baffle 212 is in contact with the bottom of the storage tank 201.

[0025] The effect achieved by the entire Embodiment 1 is that when adjusting the pulp flow rate, the motor 203 is started. When the output end of the motor 203 drives the first pulley 206 to rotate forward through the rotating rod 204, it drives the second pulley 207 through the transmission belt 205, causing the threaded rod 209 to rotate correspondingly on the inner surface of the mounting plate 208. The limiting block 216 fixedly connected to the outer surface of the threaded rod 209 rotates synchronously inside the mounting plate 208, playing a role in limiting. Under the action of threaded rotation connection, the threaded sleeve 210 arranged on the outer surface of the threaded rod 209 pushes the connecting block 211, causing the baffle 212 to move forward synchronously. The moving blocks 215 fixedly connected to both sides of the baffle 212 slide synchronously on the outer surfaces of the two fixed rods 214. The baffle 212 gradually covers the discharge hole 218 at the bottom of the storage tank 201, continuously reducing the pulp discharge channel in the storage tank 201 and the flow rate of the pulp flowing into the machine body 1, thereby reducing the pulp discharge rate. Conversely, when the output end of the motor 203 fixed in the mounting frame 202 rotates in the reverse direction, the baffle 212 gradually moves backward, continuously increasing the pulp discharge channel of the storage tank 201, thereby increasing the pulp discharge rate, playing a role in adjustment, facilitating personnel to adjust the pulp flow rate according to requirements, and solving the problem in the background technology that the pulp discharge rate of the headbox is fixed. To form papers with different thicknesses, it is necessary to adjust the running speed of the forming wire. However, in this way, it is relatively difficult to accurately control the movement speed of the forming wire.

[0026] Embodiment 2: As Figures 1-5 shown, mounting grooves 213 are symmetrically formed at the bottom of the storage tank 201. Fixed rods 214 are fixedly connected to the inner surfaces of the two mounting grooves 213. Moving blocks 215 are respectively fixedly connected to the outer surfaces of both sides of the baffle 212. The two moving blocks 215 are respectively located inside the two mounting grooves 213, and the moving blocks 215 and the fixed rods 214 are arranged in a matching manner.

[0027] The effect achieved by the entire Embodiment 2 is that during use, by symmetrically forming mounting grooves 213 at the bottom of the storage tank 201 and fixedly connecting fixed rods 214 inside the mounting grooves 213, when the baffle 212 drives the two moving blocks 215 to move back and forth, they slide correspondingly along the outer surfaces of the two fixed rods 214, playing a role in limiting, preventing their positions from shifting and affecting the adjustment of the pulp discharge, and having high practicality.

[0028] Working principle: When adjusting the pulp flow rate, start the motor 203. When the output end of the motor 203 drives the first pulley 206 to rotate forward through the rotating rod 204, the second pulley 207 is driven by the transmission belt 205, so that the threaded rod 209 rotates correspondingly on the inner surface of the mounting plate 208. The limiting block 216 fixedly connected to the outer surface of the threaded rod 209 rotates synchronously inside the mounting plate 208, playing a limiting role. Under the action of threaded rotation connection, the threaded sleeve 210 arranged on the outer surface of the threaded rod 209 pushes the connecting block 211, so that the baffle 212 moves forward synchronously. The moving blocks 215 fixedly connected to both sides of the baffle 212 slide synchronously on the outer surfaces of the two fixed rods 214. The baffle 212 gradually covers the discharge hole 218 at the bottom of the storage tank 201, so that the pulp discharge channel in the storage tank 201 continuously decreases, and the flow rate of the pulp flowing into the machine body 1 decreases, thereby reducing the pulp discharge rate. On the contrary, when the output end of the motor 203 fixed in the mounting frame 202 rotates reversely, the baffle 212 gradually moves backward, so that the pulp discharge channel of the storage tank 201 continuously increases, thereby increasing the pulp discharge rate, playing a role in adjustment, facilitating personnel to adjust the pulp flow rate according to needs. By symmetrically arranging mounting grooves 213 at the bottom of the storage tank 201, and fixedly connecting fixed rods 214 in the mounting grooves 213, when the baffle 212 drives the two moving blocks 215 to move back and forth, they slide correspondingly along the outer surfaces of the two fixed rods 214, playing a limiting role to prevent their positions from shifting and affecting the adjustment of pulp discharge, with high practicability.

[0029] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
