Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a tile laminating machine, in particular to a tile laminating machine with a servo motor synchronously driving a compression roller system. BACKGROUND

[0002] In the production process of corrugated paperboard, the preparation of double corrugated two-layer paperboard with convex-to-convex and double corrugated paperboard is crucial. At present, the structure details of the preparation single machine (tile laminating machine) of double corrugated two-layer paperboard with convex-to-convex and double corrugated paperboard described in the Chinese patent with the announcement number CN219903599U can be referred to: a synchronous transmission mechanism driving the upper and lower compression concave roller system adopts a first and a second synchronous gear with non-backlash and adjustable phase, at

[0050] : in order to facilitate the replacement and maintenance of the upper and lower compression concave roller system, the synchronous transmission mechanism is led out of the gear box and arranged in the gear box, the two output shafts of the gear box are connected with the flange at one end of the universal joint coupling, and the flange at the other end of the universal joint coupling is connected with the transmission shaft end flanges of the upper and lower compression concave roller system.

[0003] The reason for adopting the universal joint coupling transmission is that the upper and lower tile rollers are pressure vessels with internal steam, and when the normal working temperature is about 160 degrees, the length direction thermal expansion value of the two is about 6 millimeters, the total combined value of the radius thermal expansion of the two is between 0-1.5 millimeters, and the thickness of the raw paper changes in the gap due to continuous replacement in the work, so the gap between the upper and lower tile rollers is required to be adjustable. Based on this reason, the universal joint coupling is required to be adjustable up and down, forward and backward, and left and right, and the telescopic universal joint coupling is a good choice, but as a mechanical transmission part, it is not a precise component. There is a gap between the telescopic spline and the spline sleeve, and there is also a gap in the universal joint part. The transmission gap generated when the speed is increased or decreased during the production of paperboard can cause the convex-to-convex to be not well aligned, and there is a small defect. Moreover, the phase adjustment of the gear and the output shaft of the gear transmission box is manually adjusted, and the adjustment and correction are relatively troublesome, and cannot achieve intelligent and digital precise adjustment.

[0004] In actual production of double corrugated two-layer paperboard with convex-to-convex and double corrugated paperboard, the alignment of the convex-to-convex is ensured by the following key conditions: 1. The diameters of the upper and lower tile rollers are absolutely the same, the concave-convex points are absolutely evenly divided on the 360-degree roller, and the tooth division degree must be the same. However, due to the process limitations of the current grinding machine, there is a small error in the roller diameter and the tooth division degree; 2. The transmission chain links including the synchronous gear and the universal joint coupling require no gap, otherwise the transmission gap generated when the speed is increased or decreased will cause the convex-to-convex to be not well aligned.

[0005] In order to reduce the situation that the convex-to-convex phase is not well aligned, a new mechanism of a servo motor synchronously driving a compression roller system is urgently needed. CONTENT OF THE UTILITY MODEL

[0006] In order to reduce the convex-to-convex phase misalignment, the application provides a servo motor synchronous driving pressure roller system of a tile laminating machine.

[0007] The application provides a servo motor synchronous driving pressure roller system of a tile laminating machine, which adopts the following technical scheme:

[0008] A servo motor synchronous driving pressure roller system of a tile laminating machine comprises a rack, an upper pressure concave roller system, a lower pressure concave roller system and a transmission system,

[0009] The profiled roller surface tooth shape of the upper pressure concave roller system is U-shaped or partial U-shaped structure, and the profiled roller surface tooth shape of the lower pressure concave roller system is UV compound or partial V-shaped structure; the upper pressure concave roller system comprises an upper pressure concave roller and an upper tile roller rotatably arranged on the rack, and the lower pressure concave roller system comprises a lower pressure concave roller and a lower tile roller rotatably arranged on the rack;

[0010] The upper tile roller and the lower tile roller are arranged adjacently, and the convex point width of the upper tile roller is 1.5 to 2.5 times that of the lower tile roller;

[0011] The transmission system comprises two groups of water-cooled servo motors, and is directly connected with the transmission shaft ends of the upper and lower tile rollers one by one.

[0012] By adopting the above technical scheme, the convex point width of the upper tile roller is nearly one time larger than that of the lower tile roller, so that the corresponding range of the lower convex point and the upper convex point is increased by nearly one time, and the phenomenon that the convex-to-convex cannot be well aligned is improved. The water-cooled servo motors in the transmission system are directly connected with the transmission shaft ends of the upper and lower tile rollers, avoiding the transmission gap problem caused by the telescopic universal joint coupling in the traditional transmission mode, reducing the convex-to-convex phase misalignment caused by the transmission gap, and avoiding the disadvantage that the conventional servo motor cannot work in a high temperature environment (because high temperature will affect the physical properties, positioning accuracy and service life of the conventional servo motor). By means of the unique position control mode of the water-cooled servo motor, the rotation of the upper and lower tile rollers can be accurately controlled, the stability of the equipment operation and the convex-to-convex sticking accuracy are improved, and the production quality of the double-corrugated two-layer paperboard is improved.

[0013] Optionally, the tail ends of the two water-cooled servo motors are provided with encoders for dynamically adjusting the angular displacement difference between the two water-cooled servo motors.

[0014] By adopting the above technical scheme, the encoders are arranged at the tail ends of the two water-cooled servo motors, so that the angular displacement of the two water-cooled servo motors can be monitored in real time. The encoder can feed back the angular displacement information of the motor to the control system, and when the angular displacement deviation of the two motors is detected, the control system can dynamically adjust the motor in time, so that the angular displacement of the two motors remains consistent, thereby ensuring the synchronous rotation of the upper and lower tile rollers, further reducing the convex-to-convex phase misalignment, and improving the accuracy and stability of the convex-to-convex sticking in the corrugated paperboard production process.

[0015] Optionally, the water-cooled servo motor is fixed with a mounting seat between the frame, and the mounting seat is internally provided with a circulating water cooling channel.

[0016] By adopting the above technical scheme, the water-cooled servo motor is fixed with the mounting seat provided with the circulating water cooling channel between the frame, and the circulating water cooling channel can effectively take away the heat generated by the water-cooled servo motor during operation, so as to ensure that the motor operates in a suitable temperature environment. Stable operating temperature helps to improve the performance and reliability of the motor, reduces motor failure and performance degradation caused by excessively high temperature, and further ensures the stability of the upper and lower roller transmission.

[0017] Optionally, the water-cooled servo motor is selected to have an output torque ≥1000 N·m and a positioning accuracy ≤±0.1°.

[0018] By adopting the above technical scheme, the water-cooled servo motor with an output torque ≥1000 N·m and a positioning accuracy ≤±0.1° is selected. The limited range of output torque can provide sufficient power for the rotation of the upper and lower rollers, ensuring that the motor can stably drive the roller to rotate even if it encounters a relatively large resistance during production. The high-precision positioning accuracy can ensure the positional accuracy of the upper and lower rollers during rotation and accurately control the phase relationship of the convex-to-convex.

[0019] Optionally, a straight connection coupling is arranged at each of the positions where the two water-cooled servo motors are directly connected to the upper and lower rollers, and the straight connection coupling is a rigid flange coupling and is located in the mounting seat.

[0020] By adopting the above technical scheme, the rigid flange coupling has good rigidity and connection stability, can effectively transmit the power of the motor, and reduce the loss and deviation in the power transmission process. At the same time, the rigid connection avoids the gap problem of the traditional coupling, ensures the synchronous rotation of the upper and lower rollers and the motor, and further improves the phase accuracy of the convex-to-convex. The mounting seat protects the rigid flange coupling from damage caused by external factors, ensuring the reliability and stability of the transmission system.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. By optimizing the structure of the upper and lower compression roller system and the design of the width of the convex points of the upper and lower rollers, and combining the direct transmission mode of the water-cooled servo motor, the corresponding range of the convex points is effectively increased, the traditional transmission gap problem is avoided, the situation of poor alignment of the convex-to-convex phase is reduced, and the production quality of the double-corrugated two-layer paperboard is improved.

[0023] 2. The water-cooled servo motor tail end is provided with an encoder, which can monitor and dynamically adjust the angular displacement difference of the two motors in real time, ensure the synchronous rotation of the upper and lower tile rollers, and further improve the accuracy and stability of the convex-to-convex sticking.
