Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a dewatering mechanism with high working efficiency. Background Technology

[0002] Papermaking is an important invention of the ancient Chinese working people. It has two forms: machine-made and handmade. Machine-made papermaking is a continuous process on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, initially dewatered on the wire section of the papermaking machine to form a wet sheet, then further dewatered by pressing, and finally dried to form paper. Papermaking machinery includes equipment for raw material preparation, pulping, papermaking, and the production of finished rolls or sheets, as well as the processing of paper and paperboard. Paper dewatering equipment is an essential component used in papermaking dewatering.

[0003] Authorized publication number CN214401200U discloses a paper machine press dewatering mechanism, relating to the field of paper machine technology, to solve the problem that in existing press dewatering mechanisms, debris on the pressure rollers easily adheres to the next batch of paper during rotation, causing paper contamination. The mechanism includes a main body, a chute, a pressure plate, and a transverse groove. A drive motor is mounted on the side of the main body, and mounting plates are installed on the front and rear sides of the main body. The chute has an inclined structure and is located on the side of the main body. The pressure plate has an arc-shaped groove on its side, which is fitted to the bottom of a rotating rod, and the pressure plate is located inside the main body. The transverse groove is located on the side of the main body, and a scraper outside the transverse groove is fitted to the side of the rotating rod. During paper press dewatering, the chute can be used to adjust the pressing force according to different types of paper, and the transverse groove can be used to clean debris and water stains adhering to the pressure rollers.

[0004] However, in actual use, it was found that adjusting the pressing force of the equipment requires two workers to work together and rotate two threaded rods simultaneously to adjust the position of the rotating rod, which increases labor costs and reduces the practicality of the device. Therefore, we propose a dehydration mechanism with high working efficiency to solve this problem. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a dehydration mechanism with high working efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency dehydration mechanism includes:

[0008] A U-shaped base and an adjustment mechanism are provided. The adjustment mechanism is mounted on the U-shaped base and is used to adjust the squeezing force during dehydration. A main drive motor is fixedly installed on the front side and the main drive motor is fixedly installed on the rear side of the U-shaped base. A main rotating shaft is rotatably installed between the inner walls of the front and rear sides of the U-shaped base. The front end of the output shaft of the main drive motor and the front end of the main rotating shaft both penetrate the U-shaped base and extend to its front side. A main gear is fixedly sleeved on the front end of the output shaft of the main drive motor, and an auxiliary gear is fixedly sleeved on the front end of the main rotating shaft. The main gear and the auxiliary gear mesh with each other. Heating rollers are fixedly sleeved on the outer sides of both the main drive motor and the main rotating shaft.

[0009] Preferably, the adjustment mechanism includes two through slots, which are respectively opened on the front and rear sides of the U-shaped base. A bidirectional screw is rotatably installed on the inner wall of the bottom of the through slot on the rear side. The top end of the bidirectional screw passes through the through slot and extends to the top of the U-shaped base.

[0010] Preferably, an mounting plate is fixedly installed on the rear side of the U-shaped base, an auxiliary drive motor is fixedly installed on the top of the mounting plate, a transmission worm is fixedly installed on the outer side of the output shaft of the auxiliary drive motor, and a transmission worm wheel is fixedly sleeved on the top of the bidirectional screw, with the transmission worm meshing with the transmission worm wheel.

[0011] Preferably, a guide rod is fixedly installed between the top inner wall and the bottom inner wall of the through groove on the front side. Two main sliding bases are threadedly connected to the outer side of the bidirectional screw, and two auxiliary sliding bases are slidably connected to the outer side of the guide rod. A secondary drive motor is fixedly installed on the front side of the lower auxiliary sliding base.

[0012] Preferably, the rear end of the secondary drive motor passes through and is rotatably connected to the main sliding base located below. An auxiliary rotating shaft is rotatably installed between the main sliding base located above and the auxiliary sliding base. Dewatering rollers are fixedly sleeved on the outer side of both the output shaft of the secondary drive motor and the outer side of the auxiliary rotating shaft.

[0013] Preferably, the bottom of the U-shaped base is provided with a water outlet, and a water guiding plate is fixedly installed on the bottom of the U-shaped base.

[0014] In this invention, a high-efficiency dewatering mechanism is described. The output shaft of a secondary drive motor rotates, causing the lower dewatering roller to rotate, which in turn moves the paper to the right. As the paper towel moves to the right, the friction force causes the upper dewatering roller to rotate, thereby squeezing and dewatering the paper. The squeezed paper towel then passes through two heating rollers. At the same time, the main drive motor is started, and the output shaft of the main drive motor rotates, causing the lower roller to rotate. This, in turn, causes the main gear and auxiliary gear to mesh, thereby driving the upper heating roller to rotate. This allows the two heating rollers to further dry the dewatered paper, significantly improving the dewatering efficiency of the device.

[0015] In this utility model, a high-efficiency dewatering mechanism is described. When the squeezing force during dewatering needs to be adjusted, an auxiliary drive motor is activated. The output shaft of the auxiliary drive motor rotates, causing the transmission worm and transmission worm wheel to mesh, thereby driving the bidirectional screw to rotate. This causes the two main sliding bases to move closer or further apart, and consequently, the two auxiliary sliding bases also move closer or further apart. This allows the distance between the two dewatering rollers to be adjusted according to the paper specifications, thus greatly improving the applicability of the device.

[0016] This utility model has a reasonable structural design. It uses two heating rollers to re-dry the dehydrated paper, which greatly improves the dehydration efficiency of the device. By adjusting the distance between the two dehydration rollers according to the paper specifications, the applicability of the device can be greatly expanded. Attached Figure Description

A main gear 5 is fixedly sleeved on the front end of the output shaft of the main drive motor 3, and an auxiliary gear 6 is fixedly sleeved on the front end of the main rotating shaft 4. The main gear 5 and the auxiliary gear 6 mesh with each other. Heating rollers 7 are fixedly sleeved on the outer sides of both the main drive motor 3 and the main rotating shaft 4. The squeezing force during dehydration can be adjusted by the adjustment mechanism 2.

[0024] In this utility model, the adjustment mechanism 2 includes two through slots 201, which are respectively opened on the front and rear sides of the U-shaped base 1. A bidirectional screw 202 is rotatably installed on the inner wall of the bottom of the through slot 201 on the rear side. The top end of the bidirectional screw 202 passes through the through slot 201 and extends to the top of the U-shaped base 1. The through slot 201 can support the bidirectional screw 202.

[0025] In this utility model, a mounting plate 203 is fixedly installed on the rear side of the U-shaped base 1, an auxiliary drive motor 204 is fixedly installed on the top of the mounting plate 203, a transmission worm 205 is fixedly installed on the outer side of the output shaft of the auxiliary drive motor 204, and a transmission worm wheel 206 is fixedly sleeved on the top of the bidirectional screw 202. The transmission worm 205 and the transmission worm wheel 206 mesh with each other. The rotation of the output shaft of the auxiliary drive motor 204 drives the transmission worm 205 and the transmission worm wheel 206 to mesh, thereby driving the bidirectional screw 202 to rotate.

[0026] In this utility model, a guide rod 207 is fixedly installed between the top inner wall and the bottom inner wall of the through groove 201 located on the front side. Two main sliding bases 208 are threadedly connected to the outer side of the bidirectional screw 202. Two auxiliary sliding bases 209 are slidably connected to the outer side of the guide rod 207. A secondary drive motor 210 is fixedly installed on the front side of the lower auxiliary sliding base 209. The bidirectional screw 202 can support the main sliding bases 208.

[0027] In this invention, the rear end of the secondary drive motor 210 passes through the lower main sliding base 208 and is rotatably connected to it. An auxiliary rotating shaft 211 is rotatably installed between the upper main sliding base 208 and the auxiliary sliding base 209. Dewatering rollers 212 are fixedly sleeved on the outer side of the output shaft of the secondary drive motor 210 and the outer side of the auxiliary rotating shaft 211.

The water squeezed out can be guided to the water outlet 213 for discharge through the water guiding plate 214.

[0029] In this invention, during use, the paper to be dehydrated is first passed between two dehydration rollers 212. Then, the secondary drive motor 210 is started, and the output shaft of the secondary drive motor 210 rotates, causing the lower dehydration roller 212 to rotate, moving the paper to the right. As the paper towel moves to the right, the friction force causes the upper dehydration roller 212 to rotate, thus squeezing and dehydrating the paper. The squeezed paper towel is then passed through two heating rollers 7. At the same time, the main drive motor 3 is started, and the output shaft of the main drive motor 3 rotates, causing the lower roller to rotate. Simultaneously, the main gear 5 meshes with the auxiliary gear 6, thereby driving the upper heating roller 7 to rotate. The movement of the rollers 212 allows the two heating rollers 7 to further dry the dewatered paper, significantly improving the dewatering efficiency of the device. When the squeezing force during dewatering needs to be adjusted, the auxiliary drive motor 204 is activated. The output shaft of the auxiliary drive motor 204 rotates, causing the transmission worm 205 to mesh with the transmission worm wheel 206, thereby driving the bidirectional screw 202 to rotate. This causes the two main sliding bases 208 to move closer or further apart, and consequently, the two auxiliary sliding bases 209 to move closer or further apart as well. This allows the distance between the two dewatering rollers 212 to be adjusted according to the paper specifications, thus greatly expanding the applicability of the device.
