Description

Technical Field

[0001] This utility model relates to the field of papermaking machine technology, and in particular to a pressing mechanism for an energy-saving papermaking machine. Background Technology

[0002] Paper machines typically consist of six parts: flow feeding, pressing, forming, drying, calendering, and winding. The pressing section is an important component. The core of the pressing mechanism in an energy-saving paper machine is to reduce subsequent energy consumption through efficient dewatering, optimize its own structure to reduce operating costs, and at the same time play a key role in improving paper performance.

[0003] Patent CN221167225U discloses a pressing mechanism for an energy-saving paper machine, belonging to the field of paper machine technology. It includes a mounting plate on which, along the direction of travel of the nonwoven fabric, are sequentially and spaced apart a first pressing component, a shaping component, and a second pressing component to squeeze water from the unshaped pulp on the nonwoven fabric. The first pressing component includes first support plates respectively disposed on the front and rear side walls of the mounting plate, and a pair of first pressure rollers disposed vertically between the two first support plates. This invention can not only meet the papermaking requirements of different processes but also quickly and accurately squeeze out excess water from the pulp, improving work efficiency.

[0004] The aforementioned patent lacks a paper residue filtration and cleaning mechanism during use. It only recovers the water squeezed out of the pulp through a recycling tank, without effectively treating the paper residue generated during the pressing process. The paper residue may mix into the recycled water, affecting the water resource recycling effect, and may also clog pipes and other equipment. Based on this, an energy-saving paper machine pressing mechanism is proposed for improvement. Utility Model Content

[0005] In view of the problem that the above-mentioned device lacks a filtration and cleaning mechanism for paper residue during the moisture recovery process, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a pressing mechanism for an energy-saving paper machine, including a base plate, a water collection trough at the top of the base plate, a water collection pipe fixedly connected to the bottom of the water collection trough, a sliding groove at one end of the base plate, and a filtering mechanism for filtering. A filter plate is fixedly connected to the middle of the inner wall of the water collection tank. The filter plate has a herringbone design. A through groove is opened in the middle of the top of the filter plate. A motor is fixedly installed at the top of the bottom plate extension plate. A lead screw is fixedly sleeved on the output shaft of the motor. One end of the lead screw is rotatably connected to the inner wall of the water collection tank. A threaded sleeve is threaded on the surface of the lead screw. A connecting block is fixedly connected to the top of the threaded sleeve. The connecting block is slidably connected to the inner wall of the through groove. Slag pushers are fixedly connected to both sides of the through groove. The bottom end of the slag pusher contacts the top of the filter plate.

[0007] As a preferred embodiment, the water collection tank is connected to the inside of the chute, and a slag storage box is slidably connected to the inner wall of the chute.

[0008] As a preferred embodiment, the screw sleeve is fixedly connected to both sides with a fixing rod, the top of the fixing rod has several grooves, the bottom wall of several grooves is movably connected with a spring, and the top of the spring is fixedly connected to a slag-removing rod.

[0009] As a preferred embodiment, the top slag rod is slidably connected to the inner wall of the groove, the top end of the top slag rod is fitted into the filter hole inside the filter plate, and the top end of the top slag rod has a hemispherical design.

[0010] As a preferred embodiment, an arc-shaped protective cover is provided above the channel, and both ends of the arc-shaped protective cover are fixedly connected to the inner wall of the water collection tank.

[0011] As a preferred embodiment, a first pressing component is provided on one side of the top of the base plate, a second pressing component is provided on the other side of the top of the base plate, and a shaping component is provided between the first pressing component and the second pressing component.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model can effectively intercept paper scraps through the filter plate, avoiding the trouble of subsequent recycling caused by paper scraps mixed into the waste liquid.

[0013] 2. This utility model, through the design of a fixing rod, groove, spring, and top slag rod, can prevent the filter holes from being blocked by paper residue, thus avoiding a decrease in filtration efficiency. It ensures that the waste liquid can smoothly pass through the filter plate and enter the bottom of the water collection tank, maintaining the continuity of the entire filtration system. Moreover, it eliminates the need for manual cleaning, reducing the maintenance intensity of the staff and improving the automation level of equipment operation. The arc-shaped protective cover design can prevent paper material and impurities that fall during the pressing process from entering the inside of the trough, reducing the accumulation of dirt in the trough and extending the service life of the equipment.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a pressing mechanism for an energy-saving paper machine, including a base plate 1, a water collection trough 11 at the top of the base plate 1, a water collection pipe 12 fixedly connected to the bottom of the water collection trough 11, a sliding groove 13 at one end of the base plate 1, and a filtering mechanism 4 for filtering. A filter plate 41 is fixedly connected to the middle of the inner wall of the water collection tank 11. The filter plate 41 is designed in a herringbone shape. A through groove 4101 is opened in the middle of the top of the filter plate 41. A motor 43 is fixedly installed at the top of the extension plate of the bottom plate 1. A lead screw 44 is fixedly sleeved on the output shaft of the motor 43. One end of the lead screw 44 is rotatably connected to the inner wall of the water collection tank 11. A threaded sleeve 45 is threaded on the surface of the lead screw 44. A connecting block 46 is fixedly connected to the top of the threaded sleeve 45. The connecting block 46 is slidably connected to the inner wall of the through groove 4101. A slag pusher plate 47 is fixedly connected to both sides of the through groove 4101. The bottom end of the slag pusher plate 47 is in contact with the top of the filter plate 41. The interior of the water collection tank 11 is connected to the interior of the slide 13, and the inner wall of the slide 13 is slidably connected to the slag storage box 48. A first pressing component 2 is provided on one side of the top of the base plate 1, and a second pressing component 21 is provided on the other side of the top of the base plate 1. A shaping component 3 is provided between the first pressing component 2 and the second pressing component 21.

[0018] Specifically, the paper stock first undergoes preliminary pressing in the first pressing assembly 2 to remove some moisture; then it enters the shaping assembly 3 to initially fix the shape of the paper stock and prevent deformation during subsequent pressing; next, the paper stock is conveyed to the second pressing assembly 21 for further pressing to dehydrate and improve the dryness of the paper stock. The mixture of waste liquid and a small amount of paper residue generated during the pressing process will first fall onto the filter plate 41. The water enters the bottom of the water collection tank 11 through the filtration effect of the filter plate 41, while the paper residue is intercepted at the top of the filter plate 41. When the motor 43 is started, its output shaft drives the lead screw 44 to rotate. When the lead screw 44 rotates, the screw sleeve 45 moves along the surface of the lead screw 44, and then drives the slag pusher plate 47 to slide on the top of the filter plate 41 through the connecting block 46. The slag pusher plate 47 pushes the paper scraps intercepted at the top of the filter plate 41 toward the slag storage box 48. The paper scraps enter the slag storage box 48 through the connection between the water collection tank 11 and the slide 13 for temporary storage. When the paper scraps in the slag storage box 48 accumulate to a certain amount, the slag storage box 48 can be pulled out from the slide 13 to clean the internal residue. The filtered waste liquid collected at the bottom of the water collection tank 11 is discharged through the water collection pipe 12 and can be recycled and reused to achieve energy saving. This design effectively intercepts paper scraps through filter plate 41, preventing them from mixing into the waste liquid and causing trouble for subsequent recycling. The motor 43 drives the slag pusher 47 to move, which can automatically push the paper scraps at the top of filter plate 41 to the slag storage box 48, which can clean the paper scraps on filter plate 41 in time, avoid affecting the filtration effect of filter plate 41, ensure the continuity and stability of waste liquid treatment, reduce water waste, save manpower and production costs, and conform to the concept of energy conservation.

[0019] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a fixing rod 5 is fixedly connected to both sides of the screw sleeve 45, and a plurality of grooves 51 are opened at the top of the fixing rod 5. A spring 52 is movably connected to the bottom wall of the plurality of grooves 51, and a top slag rod 53 is fixedly connected to the top of the spring 52. The top slag rod 53 is slidably connected to the inner wall of the groove 51, and the top end of the top slag rod 53 is embedded in the filter hole inside the filter plate 41. The top end of the top slag rod 53 is designed in a hemispherical shape. An arc-shaped protective cover 42 is provided above the through channel 4101, and both ends of the arc-shaped protective cover 42 are fixedly connected to the inner wall of the water collection tank 11.

[0020] During use, when the screw sleeve 45 moves with the lead screw 44, the fixing rod 5 moves accordingly. The fixing rod 5 drives the top slag rod 53 to move. The top of the top slag rod 53 is fitted into the filter hole of the filter plate 41, and the top is hemispherical. It can push and clean the fine paper residue in the filter hole during the movement, ensuring that the waste liquid can pass smoothly through the filter plate 41 into the bottom of the water collection tank 11. At the same time, the elasticity of the spring 52 makes the top slag rod 53 always self-adaptively fitted with the filter hole, eliminating the need for manual cleaning, reducing the maintenance intensity of the staff, and improving the automation level of the equipment operation. The arc-shaped protective cover 42 can prevent paper material and impurities that fall during the pressing process from entering the inside of the through groove 4101, reduce the accumulation of dirt in the through groove 4101, and extend the service life of the equipment.
