Description

Technical Field

[0001] The utility model relates to the technical field of flexible material processing equipment, and particularly relates to a novel variable traverse and variable speed device. Background Art

[0002] Existing variable traverse and variable speed devices are divided into two categories. One is mechanical, which realizes speed change through mechanical transmission. The other directly uses a servo motor for speed change. The advantage of the servo type is its simple structure and convenient code change. However, it has a big defect that the equipment speed cannot be increased too fast. The reason for the low speed is the regenerative load alarm of the servo motor. The generation of the regenerative load is because when the servo motor is decelerating, it needs to absorb the mechanical energy of the load. When the mechanical energy of the load is too large and exceeds the limit that the servo motor can absorb, the motor will alarm and stop to prevent damage. The faster the equipment runs, the greater the mechanical energy. The regenerative load makes the equipment unable to run too fast, even though there is still a lot of unused motor torque.

[0003] To solve this problem, the utility model patent with the authorization publication number CN220581613U provides a speed superposition type variable traverse and variable speed device. The speed superposition type variable traverse and variable speed device provided by this utility model patent avoids the influence of the regenerative load on the servo motor by different movement modes of multiple motors and uses a planetary reducer to superpose different speeds for speed change, thereby increasing the upper limit of the equipment speed of the servo type speed change. In this speed superposition type variable traverse and variable speed device, since only one common motor is provided, in order to drive the planetary reducers on both sides of the frame, a common shaft passing through the frame and extending to both sides needs to be installed. However, due to the relatively troublesome installation of the common shaft, the complexity of the overall assembly of the equipment will increase to a certain extent, so it needs to be further improved. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a novel variable traverse and variable speed device that does not require a common shaft passing through the frame and extending to both sides, and can reduce the complexity of the overall assembly of the equipment to a certain extent.

[0008] Further, the driving pulleys, input pulleys, output pulleys, and driven pulleys are all synchronous toothed pulleys. The first transmission belt and the second transmission belt are both synchronous toothed belts.

[0009] Further, the planetary reducer component includes a second planetary reducer, a machine base, a front bearing, and a rear bearing.

[0011] Further, the output end of the first planetary speed reducer is in transmission connection with the connecting shaft, and the driving pulley is installed on the connecting shaft.

[0012] Further, both the main motor and the auxiliary motor are servo motors.

[0013] Further, the main motor operates at a constant speed, and the auxiliary motor operates at a variable speed with forward and reverse rotations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present utility model through specific embodiments.

[0020] Such as Figures 1 to 3As shown in the figure, a new type of variable cross-section and variable speed device of the present utility model includes a frame, a transmission swing arm 11, a variable cross-section component 2, a secondary transmission shaft sleeve 3, a main motor 41, and a secondary motor 42. The main motor 41 and multiple secondary motors 42 are provided on both sides outside the frame. The output end of the main motor 41 is provided with a first planetary reducer 5. The output ends of the first planetary reducer 5 are respectively provided with multiple driving pulleys 61. The output ends of the multiple secondary motors 42 are respectively provided with planetary reducer assemblies 7. The planetary reducer assemblies 7 are provided with input pulleys 62 and output pulleys 63. The driving pulley 61 is in transmission connection with the corresponding input pulley 62 through a first transmission belt 64. Multiple secondary transmission shaft sleeves 3 are provided on both sides of the frame. The multiple secondary transmission shaft sleeves 3 are sequentially sleeved and rotatably connected coaxially. The outermost secondary transmission shaft sleeve 3 is rotatably installed on the frame through a pedestal bearing 31. Driven pulleys 65 located outside the frame are installed on the multiple secondary transmission shaft sleeves 3. The output pulley 63 is in transmission connection with the corresponding driven pulley 65 through a second transmission belt 66. Transmission swing arms 11 located inside the frame are installed on the multiple secondary transmission shaft sleeves 3. The multiple transmission swing arms 11 are evenly spaced along the circumferential direction of the secondary transmission shaft sleeve 3. The variable cross-section component 2 is installed at one end of each of the multiple transmission swing arms 11.

[0021] By providing the main motor 41 on both sides outside the frame, in this way, the two main motors 41 can be respectively in transmission connection with the planetary reducer assemblies 7 on the corresponding side. Thus, there is no need to set up a common shaft passing through the frame and extending to both sides, and the complex installation of the common shaft can be omitted, thereby reducing the complexity of the overall assembly of the device to a certain extent. In addition, through the setting of the driving pulley 61, the first transmission belt 64, and the input pulley 62, it is convenient to realize the belt transmission connection between the connecting shaft 9 and the planetary reducer assembly 7. Through the setting of the output pulley 63, the second transmission belt 66, and the driven pulley 65, it is convenient to realize the belt transmission connection between the planetary reducer assembly 7 and the secondary transmission shaft sleeve 3. In this way, by adopting belt transmission for the transmission connection, the running noise can be relatively small, and the installation and maintenance are also simpler, and the cost is relatively low.

[0022] The new variable traverse speed device further includes auxiliary swing arms 12. A plurality of the auxiliary swing arms 12 are provided on both sides inside the frame. The plurality of auxiliary swing arms 12 are evenly spaced along the circumferential direction of the extension shaft 81 of the circular cam 8 and are rotatably installed on the extension shaft 81. The circular cam 8 is arranged inside the frame. Both ends of the circular cam 8 are fixedly provided with the extension shafts 81. The two extension shafts 81 are respectively rotatably installed in the corresponding innermost sub-drive shaft sleeves 3 on the corresponding side. One end of the auxiliary swing arm 12 is connected to the corresponding traverse component 2. Correspondingly, the drive swing arm 11 and the auxiliary swing arm 12 are respectively arranged on both sides of the traverse component 2 to further improve the stability of the traverse component 2 during operation.

[0023] Preferably, two sub-motors 42 are provided on both sides outside the frame. Two sub-drive shaft sleeves 3 are provided on both sides of the frame. Two drive swing arms 11 and two auxiliary swing arms 12 are provided on both sides inside the frame.

[0024] Preferably, the driving pulley 61, the input pulley 62, the output pulley 63, and the driven pulley 65 are all synchronous toothed belt pulleys. The first transmission belt 64 and the second transmission belt 66 are both synchronous toothed belts, thereby further ensuring accurate transmission and ensuring a high transmission efficiency.

[0025] Correspondingly, the planetary speed reducer assembly 7 includes a second planetary speed reducer 71, a machine base 72, a front bearing 73, and a rear bearing 74. The front and rear ends of the second planetary speed reducer 71 are respectively rotatably installed in the machine base 72 through the front bearing 73 and the rear bearing 74. The input pulley 62 is installed on the outer shell of the second planetary speed reducer 71. A notch 721 corresponding to the input pulley 62 is provided on the machine base 72. One end of the second planetary speed reducer 71 is a motor input end 75, and the other end of the second planetary speed reducer is provided with an output shaft 76. The output pulley 63 is installed on the output shaft 76. Through the setting of the notch 721, it is convenient for the first transmission belt 64 to pass through the notch 721 of the base 72 and wind around the input pulley 62 for transmission connection.

[0026] In addition, the first planetary speed reducer 5 is fixedly installed on the frame through a first mounting seat. The machine base 72 is fixedly installed on the frame through a second mounting seat.

[0027] Correspondingly, the output end of the first planetary speed reducer 5 is in transmission connection with the connecting shaft 9. The driving pulley 61 is installed on the connecting shaft 9.

[0028] Preferably, the main motor 41 and the auxiliary motor 42 are both servo motors, the main motor 41 performs constant speed motion, and the auxiliary motor 42 performs forward and reverse speed-changing motion.

[0029] In this way, the mechanism performing the accelerating motion can transfer mechanical energy to the mechanism performing the decelerating motion. Depending on the situation, the regenerative load can be reduced to at least one twentieth of the original value, which means that the regenerative load is no longer the main reason why the equipment cannot run fast. Under the same usage conditions, the speed change performance of the improved transverse speed change equipment is greatly improved, the energy consumption is greatly reduced, the temperature of the main motor 41 and the auxiliary motor 42 is also greatly reduced, and the service life is guaranteed.

[0030] The use method of the novel transverse speed changing device described in the utility model is as follows:

[0031] When the auxiliary motor 42 is started to perform variable speed motion (such as variable speed motion that changes according to the cosine law), and the main motor 41 is not started, the auxiliary motor 42 is connected to the driven pulley 65 on the auxiliary transmission shaft sleeve 3 through the output pulley 63 on the planetary reducer assembly 7 and the second transmission belt 66, thereby driving the transmission swing arm 11 to swing left and right; when the auxiliary motor 42 is not started and the main motor 41 is started to perform uniform speed motion, the main motor 41 is connected to the input pulley 62 on the second planetary reducer 71 through the first planetary reducer 5, the driving pulley 61 on the connecting shaft 9, the first transmission belt 64, thereby driving the second planetary reducer 71 to perform uniform speed motion, and then the output pulley 63, the second transmission belt 66 and the auxiliary The driven pulley 65 on the transmission sleeve 3 is connected for transmission, thereby driving the transmission swing arm 11 to rotate at a uniform speed; when the auxiliary motor 42 and the main motor 41 work at the same time, the movements of the auxiliary motor 42 and the main motor 41 are simultaneously input into the second planetary reducer 71, and the combined movement is output by the output shaft 76 of the second planetary reducer 71, and is connected for transmission with the driven pulley 65 on the auxiliary transmission sleeve 3 through the output pulley 63 and the second transmission belt 66 to drive the transmission swing arm 11 to rotate. The transmission swing arm 11 will superimpose the speed change movement of the auxiliary motor 42 on the basis of the uniform motion, thereby realizing speed change. In this way, the speed change of the transmission swing arm 11 is completed by speed superposition to increase the speed upper limit of the equipment.

[0032] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
