Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, and in particular relates to a drying machine for paper processing. Background Art

[0002] Paper drying is a key step in the papermaking process. Its main purpose is to evaporate the moisture in the wet paper to make the paper reach the required dryness. Paper drying machines usually use multiple groups of drying cylinders to dry the paper.

[0003] The drying cylinder is a hollow cylinder made of cast iron with covers at both ends. It consists of a cylinder body and cylinder covers at both ends. The outer diameter is usually 1000-3000mm. During operation, steam is passed through the cylinder to dry and iron the transported paper. When using a drying cylinder, in order to prevent paper hair from sticking to the surface of the drying cylinder, a stripping agent is usually sprayed on the outer wall of the drying cylinder. The stripping agent can be silicone oil. The effective time of the stripping agent is usually 5-10 minutes. The spraying of the stripping agent is usually completed by a dosing mechanism.

[0004] At present, a dosing mechanism such as a dosing mechanism of a drying cylinder with patent number CN219547434U sprays a stripping agent on both sides of the drying cylinder. However, part of the stripping agent is thrown outward due to the centrifugal force generated by the rotation of the drying cylinder, resulting in a large amount of waste. Utility Model Content

[0005] The purpose of the utility model is to provide a paper processing drying machine in view of the above-mentioned existing technical problems, so as to achieve the effect of preventing the stripping agent from splashing and wasting.

[0006] In view of this, the utility model provides a paper processing drying machine, including a machine base, on which are arranged:

[0007] A drying cylinder, both ends of which are rotatably arranged on a machine base;

[0008] A dosing mechanism, which is arranged on the side of the drying cylinder where the paper is forwardly transferred out of the drying cylinder, and is used to spray the stripping agent to the drying cylinder regularly;

[0009] The medicine receiving groove is used to receive the stripping agent dripping from the drying cylinder. The medicine receiving groove is arc-shaped and is coaxially arranged below the drying cylinder.

[0010] In the present technical solution, the stripping agent dripping from the drying cylinder can be caught by the medicine receiving trough, and the position distribution of the medicine receiving trough and the medicine adding mechanism can catch the stripping agent thrown out from the surface of the drying cylinder due to centrifugal action after the medicine adding mechanism sprays the stripping agent on the drying cylinder, thereby preventing the stripping agent from splashing and being wasted.

[0011] Furthermore, a spreading roller is arranged in the medicine receiving groove, and the spreading roller is arranged below the drying cylinder in parallel with the drying cylinder. The spreading roller is partially immersed in the stripping agent in the medicine receiving groove, and the upper part of the spreading roller contacts the outer periphery of the drying cylinder.

[0012] In the present technical scheme, the spreading roller contacts the drying cylinder and can scrape off the excessively thick stripping agent liquid on the outer peripheral surface of the drying cylinder. Since the dosing mechanism adds the agent by single-point linear movement as the drying cylinder rotates circumferentially, the spreading roller can speed up the spreading of the stripping agent on the outer periphery of the drying cylinder, and the spreading roller is partially immersed in the stripping agent in the drug receiving trough, so the stripping agent in the drug receiving trough can be transferred to the drying cylinder for a second time, which can reduce the dosing frequency of the dosing mechanism, recycle the stripping agent received by the drug receiving trough, and improve the utilization rate of the stripping agent. To ensure the effectiveness of the stripping agent, the stripping agent in the drug receiving trough needs to be poured out every day.

[0013] Furthermore, the drug adding mechanism includes:

[0014] A spraying assembly, the spraying assembly is used to spray a stripping agent onto the surface of the drying cylinder;

[0015] A sliding assembly, the sliding assembly is used to move the spray assembly along the axis of the drying cylinder;

[0016] A lifting assembly is used to move the sliding assembly and the spraying assembly as a whole toward or away from the drying cylinder in a direction perpendicular to the axis of the drying cylinder.

[0017] Furthermore, the lifting assembly comprises:

[0018] A mounting seat, the mounting seat is slidably arranged on the above-mentioned machine base, two mounting seats are arranged, corresponding to the two ends of the drying cylinder respectively, and the two ends of the sliding assembly are respectively arranged on the mounting seats;

[0019] A lifting cylinder is fixedly arranged on a machine base, and an output end of the lifting cylinder is connected to a mounting base.

[0020] Furthermore, the sliding assembly comprises:

[0021] A sliding motor, wherein the sliding motor is fixedly arranged on a mounting seat;

[0022] A screw rod, both ends of which are rotatably arranged on two mounting seats, one end of which is connected to the output end of the sliding motor, and the spraying assembly is spirally connected to the screw rod;

[0023] The guide shaft has two ends fixedly arranged on two mounting seats, the guide shaft is parallel to the screw rod, and the spraying assembly is slidably arranged on the guide shaft.

[0024] In this technical solution, when spraying is required, the piston rod of the lifting cylinder is shortened so that the sliding assembly and the spraying assembly are located below the side of the drying cylinder, and then the sliding motor is started to move the spraying assembly along the length direction of the screw rod for spraying.

[0025] Furthermore, the drying cylinder comprises:

[0026] A cylinder body, which is cylindrical and has a liquid tank and a siphon tube;

[0027] The core shaft passes through the cylinder body and is coaxial with the cylinder body and fixedly connected. The center of the core shaft is hollow. One end of the core shaft is used for passing hot steam, and the other end is used for discharging moisture. A plurality of diffusion holes are opened on the core shaft, and the diffusion holes connect the inner cavity of the cylinder body and the inner cavity of the core shaft.

[0028] Furthermore, an energy conversion component is provided in the drying cylinder, and the energy conversion component is used to convert the mechanical energy of hot steam rushing into the core shaft into thermal energy.

[0029] Furthermore, the energy conversion component comprises:

[0030] A fixed shaft, wherein the fixed shaft is fixedly disposed in the core shaft;

[0031] The wind wheel assembly is rotatably sleeved on a fixed shaft, and comprises a sleeve rod and a rotor fixedly connected to the sleeve rod, the rotor blades are inclined, and a driven rod is fixedly arranged on the periphery of the sleeve rod, and the driven rod is elastic.

[0032] In this technical solution, when hot steam rushes into the core shaft, the wheel will rotate, and the wheel will rotate with the sleeve rod and the driven rod. The driven rod is elastic and extends toward the inner wall of the core shaft under the action of centrifugal force, and will rub against the inner wall of the core shaft, thereby generating heat, which increases more heat energy inside the drying cylinder and reduces energy consumption.

[0033] Furthermore, a friction plate is provided at a position on the inner wall of the core shaft corresponding to the driven rod, and the driven rod rubs against the friction plate.

[0034] In the present technical solution, the provision of the friction plate can reduce the wear on the inner wall of the core shaft.

[0035] The beneficial effects of the utility model are:

[0036] 1. The stripping agent dripping from the drying cylinder can be caught by the medicine receiving groove, and the position distribution of the medicine receiving groove and the medicine adding mechanism can catch the stripping agent thrown out from the drying cylinder surface due to centrifugal action after the medicine adding mechanism sprays the stripping agent on the drying cylinder, thereby preventing the stripping agent from splashing and wasting.

[0037] 2. The contact between the spreading roller and the drying cylinder can scrape off the excessively thick stripping agent liquid on the outer surface of the drying cylinder. Since the dosing mechanism adds the agent in a single-point linear motion as the drying cylinder rotates circumferentially, the spreading roller can speed up the spreading of the stripping agent on the outer surface of the drying cylinder, and the spreading roller is partially immersed in the stripping agent in the drug receiving trough, so the stripping agent in the drug receiving trough can be transferred to the drying cylinder for a second time, which can reduce the dosing frequency of the dosing mechanism, recycle the stripping agent received by the drug receiving trough, and improve the utilization rate of the stripping agent.

[0038] 3. When hot steam rushes into the core shaft, it will cause the wheel to rotate, and the wheel will rotate with the sleeve rod and the driven rod. The driven rod is elastic and extends toward the inner wall of the core shaft under the action of centrifugal force, and will rub against the inner wall of the core shaft, thereby generating heat, increasing more heat energy inside the drying cylinder and reducing energy consumption.
