Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a three-dimensional drying device for producing daily paper. Background Art

[0002] In the process of producing household paper, papermaking drying cylinders are required for drying. Papermaking drying cylinders refer to machines used in papermaking machinery to continuously dry paper blanks after pulp forming.

[0003] Usually, when drying paper products, a papermaking drying cylinder needs to use a winding device to drive the formed paper blanks to continuously pass through the surface of the drying cylinder. The high steam introduced into the drying cylinder can quickly dehydrate and dry the paper blanks that bypass the surface of the drying cylinder. However, when the paper blanks are being dried, the overall tensioning force of the paper blanks may be insufficient due to reasons such as insufficient rotation angle of the tensioning roller or different elasticities of different paper blanks. At this time, a gap may be generated between the paper blanks and the drying cylinder, making it difficult for the paper blanks to contact the surface of the drying cylinder, which will lead to poor overall drying effect.

[0004] To this end, we propose a three-dimensional drying device for the production of household paper. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A three-dimensional drying device for producing household paper, such as Figure 1 - Figure 6As shown, it includes a frame 1, two steering rollers 2 are rotatably installed inside the frame 1, a drying cylinder 3 is rotatably installed inside the frame 1, high-temperature steam is introduced into the drying cylinder 3 to dry the paper products, and the drying operation can be completed after the paper products pass through the two steering rollers 2 and the drying cylinder 3. A detection and cleaning mechanism 4 is arranged inside the frame 1, and the detection and cleaning mechanism 4 can be used to perform tension detection when the paper products are dried, and the surface of the drying cylinder 3 can be cleaned after the paper products are processed.

[0026] Furthermore, the detection and cleaning mechanism 4 includes a movable shaft 41, a cleaning roller 42 and an adsorption sponge 43. The movable shaft 41 is rotatably installed inside the frame 1, and the movable shaft 41 is located on one side of the drying cylinder 3.

The cleaning roller 42 is driven by a motor, and the motor is electrically connected to the external controller. The adsorption sponge 43 is arranged on the cleaning roller 42, and the adsorption sponge 43 is adhered to the surface of the cleaning roller 42 by Velcro. The adsorption sponge 43 is made of sponge material. After the paper product is dried, the cleaning roller 42 rotates until the adsorption sponge 43 can be attached to the drying cylinder 3 and the adsorption sponge 43 is driven by the rotation of the cleaning roller 42 to clean the attachments on the surface of the drying cylinder 3; by providing the cleaning roller 42 and the adsorption sponge 43, after the paper product is dried, the movable shaft 41 is driven to rotate until the cleaning roller 42 is in contact with the drying cylinder 3, and the cleaning roller 42 is driven to rotate by the external motor to use the adsorption sponge 43 to effectively clean the attachments on the surface of the drying cylinder 3.

[0027] Furthermore, the detection and cleaning mechanism 4 also includes a pressure roller 44, a lower pressure rod 45 and a detection component. The pressure roller 44 is rotatably installed on one side of the movable shaft 41, and the lower pressure rod 45 used to connect the movable shaft 41 is rotatably installed on both sides of the lower pressure rod 45.

Two grooves are provided on the movable shaft 41, and a detection component is arranged inside the groove; by providing the pressure roller 44, the lower pressure rod 45 and the detection component, during the processing of paper products, when the paper is tightened, it will fit together with the surface of the drying cylinder 3. At this time, the paper can contact the pressure roller 44 and apply a force to the pressure roller 44 on one side. The pressure roller 44 drives the lower pressure rod 45 to rotate to one side under the force of tightening the paper and cooperates with the detection component to detect the tension of the paper, so as to ensure that the paper can fit together with the surface of the drying cylinder 3 when drying, thereby ensuring the drying effect.

[0028] Furthermore, the detection component includes a force block 411, a spring 412, an inner ring 413, a positioning pressure rod 414 and a contact sensor 415. The force block 411 is movably installed inside the groove. The force block 411 is an arc-shaped block. When the paper is tightened, the force block 411 can contact the lower pressure rod 45. The contact sensor 415 (CHM6A5-BL) is fixedly installed inside the groove. The contact sensor 415 is electrically connected to the external controller. The inner ring 413 is fixedly installed inside the groove. The spring 412 for connecting the force block 411 is fixedly installed on the inner ring 413. One end of the spring 412 is fixedly connected to the force block 411. The positioning pressure rod 414 for limiting the force block 411 is movably installed on the inner ring 413. The positioning pressure rod 414 is connected to the inner ring 413 and the spring The spring 412 is sleeved, and when the paper is tightened, the force block 411 can drive the positioning pressure rod 414 to contact with the contact sensor 415; by providing a detection component, when the paper is dried, when the paper is tightened, a force can be applied to the pressure roller 44, and the pressure roller 44 is forced to drive the lower pressure rod 45 to rotate and squeeze the force block 411. After the force is applied, the force block 411 slides into the groove and drives the positioning pressure rod 414 to contact with the contact sensor 415. At this time, the contact sensor 415 sends a prompt to the external system that the paper is tightened. On the contrary, if the contact sensor 415 is not in contact with the contact sensor 415, it means that the paper is not tightened. At this time, there is a gap between the paper and the drying cylinder 3. After receiving the feedback that the paper is not tightened, the system can make appropriate adjustments to ensure that the paper can be tightly attached to the drying cylinder 3 during drying to ensure the overall drying effect.

[0029] Furthermore, the driving mechanism 5 includes a movable disk 51, a driving short shaft 52, a linkage disk 53 and a synchronous groove 54.

When the paper products are being dried, the movable disk 51 can be driven to drive the linkage disk 53 to drive the movable shaft 41 to rotate and switch to the paper product tensioning detection state. After the paper products are processed, the movable disk 51 can be driven to drive the linkage disk 53 to drive the movable shaft 41 to rotate and switch to the state of cleaning the drying cylinder 3.

[0030] The working principle of the utility model is as follows: when the paper is dried, when the paper is tightened, a force can be applied to the pressing roller 44, and the pressing roller 44 is forced to drive the lower pressing rod 45 to rotate and squeeze the force block 411. After the force is applied to the force block 411, it slides into the groove and drives the positioning pressing rod 414 to contact the contact sensor 415. At this time, the contact sensor 415 sends a prompt to the external system that the paper is tightened. On the contrary, if the contact sensor 415 does not contact the contact sensor 415, it means that the paper is not tightened. At this time, there is a gap between the paper and the drying cylinder 3. After receiving the feedback that the paper is not tightened, the system can make appropriate adjustments. After the paper product is dried, the movable shaft 41 is driven to rotate. Until the cleaning roller 42 is in contact with the drying cylinder 3, and the cleaning roller 42 is driven to rotate by an external motor to use the adsorption sponge 43 to effectively clean the attachments on the surface of the drying cylinder 3. At the same time, when the state of the detection and cleaning mechanism 4 is switched, the movable disk 51 can be rotated to drive the driving short shaft 52 and the synchronous groove 54 to be movably connected and drive the interlocking disk 53 to rotate synchronously. When the paper product is drying, the movable disk 51 can be rotated to drive the interlocking disk 53 to drive the movable shaft 41 to rotate and switch to the paper product tensioning detection state. After the paper product processing is completed, the movable disk 51 can be rotated to drive the interlocking disk 53 to drive the movable shaft 41 to rotate and switch to the state of cleaning the drying cylinder 3.
