Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and in particular to a paper roll kinetic energy recovery and power generation device. Background Technology

[0002] In the modern papermaking industry, paper winding is a key link in the production process. When the paper winding machine is running, it mainly relies on the motor to drive the paper winding shaft to rotate to complete the paper winding operation. However, in the traditional paper winding process, a large amount of kinetic energy generated by the paper winding roller is not effectively utilized, resulting in serious energy waste. The stability of the paper winding roller during rotation is difficult to guarantee, and the existing fixing method cannot adapt to its operating requirements under different working conditions, which can easily affect the quality of paper winding and cause equipment failure. The transmission efficiency during kinetic energy recovery is poor, and there is a large loss in the energy transfer process from the paper winding roller to the generator, making it difficult to achieve efficient energy recovery. The speed corresponding to the kinetic energy generated by the paper winding roller is low, which cannot enable the generator to reach the optimal working state, resulting in low power generation efficiency. There is a lack of real-time and effective monitoring of the torque on the paper winding roller during the paper winding process. Excessive torque may cause safety hazards such as roller damage and motor overload. Utility Model Content

[0004] The purpose and effectiveness of this utility model's paper roll kinetic energy recovery power generation device are achieved through the following specific technical means:

[0005] A paper roll kinetic energy recovery and power generation device includes a mounting base; a paper roll roller is rotatably connected to the left side of the top end face of the mounting base; two hydraulic cylinders are symmetrically installed on the left side of the rear side wall of the mounting base; a rotating guide is fixedly installed in the middle of the top end face of the mounting base; a drive shaft is rotatably connected to the rotating guide; a connecting slider is slidably connected to the left side wall of the drive shaft; an auxiliary bracket is fixedly connected to the right side of the rotating guide; a connecting shaft is rotatably connected to the auxiliary bracket; and a generator is fixedly installed on the right side of the top end face of the mounting base.

[0006] Furthermore, two paper roll brackets are symmetrically installed on the left side of the top end face of the mounting base. The left and right ends of the paper roll are rotatably connected to the middle of the top end face of the paper roll bracket. The left end of the paper roll is connected to the external drive mechanism. A hexagonal connector is provided on the right side wall of the paper roll. A connecting seat is fixedly installed on the rear side wall of the mounting base at the corresponding position of the paper roll bracket. The connecting seat is hinged to the bottom of the hydraulic cylinder.

[0007] Furthermore, the two paper roll brackets of the mounting base are hinged to the rear top of opposite side walls with paper roll deflectors. The paper roll deflectors are Y-shaped. The connecting slot at the front of the paper roll deflector matches the middle of the top of the paper roll bracket. The rear end of the paper roll deflector is hinged to the telescopic end at the top of the hydraulic cylinder. A torque sensor is fixedly installed on the front top of the paper roll deflector. The bottom of the torque sensor contacts the outer wall of the paper roll.

[0008] Furthermore, a speed sensor is fixedly installed on the top left side of the rotating guide seat. The speed sensor is in contact with the outer wall of the transmission shaft. A hexagonal sliding cavity is opened in the left side wall of the transmission shaft. The connecting slider is slidably connected in the sliding cavity. A support spring is provided between the right side wall of the connecting slider and the inner wall of the sliding cavity. A hexagonal connecting slot is opened in the left side wall of the connecting slider. The connecting slot matches the connecting plug on the right side wall of the paper roll. An internal tooth groove is provided in the right side wall of the transmission shaft.

[0009] Furthermore, a circular concave cavity is provided in the left rear side wall of the auxiliary support, and three gear shafts are arranged in a ring array in the concave cavity. Planetary gears are rotatably connected to the gear shafts, and the outer side of the planetary gears meshes with the internal tooth grooves opened in the right side wall of the transmission shaft.

[0010] Furthermore, a central gear is fixedly connected to the left end of the connecting shaft rotatably connected in the right rear side wall of the auxiliary bracket. The outer side wall of the central gear meshes with the planetary gear rotatably connected in the left side wall of the auxiliary bracket. A drive gear is fixedly installed on the right end of the auxiliary bracket. The front side of the drive gear meshes with the driven gear connected to the left end of the generator shaft.

[0011] This utility model provides a paper roll kinetic energy recovery and power generation device, which has the following beneficial effects:

[0012] 1. This device can effectively convert the mechanical energy generated during the paper rolling process into electrical energy for recycling, reducing energy waste, improving energy utilization efficiency, and lowering the company's electricity costs. The recycled electricity can be used in other production processes within the paper mill, reducing the company's dependence on external power, thereby lowering production costs and enhancing the company's market competitiveness.

[0013] 2. Through the cooperation of hydraulic cylinder and paper roll holder, the paper roll can be firmly fixed. When the extension end of the hydraulic cylinder extends, the front end of the paper roll holder flips down to cooperate with the paper roll support, ensuring the stability of the paper roll during rotation. This ensures the quality and efficiency of the paper rolling process itself. The torque sensor installed on the paper roll holder can detect the torque on the roll in real time during the paper rolling process. By monitoring the torque in real time, it is possible to better prevent equipment failures or safety accidents that may be caused by abnormal torque, thus improving the safety of the entire device during operation.

[0014] 3. The kinetic energy of the paper roll is transferred to the drive shaft through the connecting slider. When the paper roll rotates and generates kinetic energy, this connection method ensures that the kinetic energy can be effectively captured by the drive shaft, forming the basis for subsequent kinetic energy recovery. Using the planetary gear principle, a series of transmissions through the internal tooth groove of the drive shaft, planetary gears, central gear, connecting shaft, drive gear and driven gear are used to amplify the rotational speed. This speed-increasing effect can increase the input speed of the generator, thereby improving the power generation efficiency and effectively converting the kinetic energy in the paper rolling process into electrical energy for recovery.

The bottom of the mounting base 102 and the hydraulic cylinder 2 are hinged together. A paper roll guide 3 is hinged to the top of the opposite rear side walls of the two paper roll supports 101 of the mounting base 1. The paper roll guide 3 is Y-shaped.

The bottom of the torque sensor 4 is connected to the outer wall of the paper roll 5. Specifically, the contact mechanism places the left and right ends of the paper roll 5 into the connecting slots 301 of the two paper roll holders 3.

[0027] A speed sensor 10 is fixedly installed on the top left side of the rotating guide seat 9. The speed sensor 10 is in contact with the outer wall of the drive shaft 8. A hexagonal sliding cavity 802 is opened in the left side wall of the drive shaft 8. The connecting slider 6 is slidably connected in the sliding cavity 802.

Under the meshing of the drive gear 1301 and the driven gear 1401, the generator 14 performs power generation operation.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When using this paper roll kinetic energy recovery power generation device, firstly, the top telescopic end of the hydraulic cylinder 2 retracts, thereby pulling the rear end of the paper roll holder 3 downward, causing the front end of the paper roll holder 3 to lift up, so that the left and right ends of the paper roll 5 are placed in the connecting slots 301 of the two paper roll holders 3. When the top telescopic end of the hydraulic cylinder 2 extends, the front end of the paper roll holder 3 can be flipped downward and cooperate with the paper roll support 101 to fix the position of the paper roll 5, thereby ensuring the stable rotation of the paper roll 5. With the cooperation of the torque sensor 4 installed on the paper roll holder 3, the torque on the roll during the paper rolling process is detected in real time, and then transmitted to the sliding cavity. Press the connecting slider 6 in body 802 so that after fixing the paper roll 5, the connecting slider 6 connects the connecting slot 601 and the connecting plug 501 under the action of the support spring 7, thereby forming a power chain. Finally, the planetary gear 12 is driven by the internal gear groove 801 at the rear end of the transmission shaft 8. The planetary gear 12 drives the central gear 1302 to rotate. Through the principle of planetary gears here, the speed increase effect is achieved. By amplifying the speed, the power generation efficiency is improved. Then, the central gear 1302 drives the drive gear 1301 through the connecting shaft 13. Under the meshing of the drive gear 1301 and the driven gear 1401, the generator 14 performs power generation operation.

[0032] By optimizing and upgrading the generator 14, a high-efficiency permanent magnet synchronous generator 14 is selected to improve the power generation efficiency and power density of the generator 14. At the same time, the heat dissipation system of the generator 14 is optimized by adopting a combination of forced air cooling and liquid cooling to ensure that the generator 14 can maintain stable performance during long-term high-load operation and reduce energy loss and equipment damage caused by heat generation.
