DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-8As shown, a connecting conveyor line for an air-conditioning outer case that is easy to adjust speed includes a connecting mechanism 10, a conveyor belt 20, a bottom plate 30, an adjusting mechanism 50 and a speed regulating mechanism 60. The connecting mechanism 10 and the conveyor belt 20 are arranged above the bottom plate 30. The adjusting mechanism 50 is fixed between the connecting mechanism 10 and the bottom plate 30. Two vertical plates 40 are symmetrically fixed on both sides of the top of the bottom plate 30. A driving roller 70 for driving the conveyor belt 20 is arranged between the two vertical plates 40. The speed regulating mechanism 60 is transmission-connected with the driving roller 70. An electric push rod 80 for adjusting the inclination angle of the conveyor belt 20 is arranged on the opposite side of the two vertical plates 40. The adjusting mechanism 50 is fixed between the bottom plate 30 and the connecting mechanism 10. The conveyor belt 20 is arranged at a certain position. Between the two vertical plates 40, and one end of the conveyor belt 20 is adjacent to the docking mechanism 10. When in use, the docking conveyor line is first arranged at an appropriate position. According to the size of the site and the position where the transfer is required, the rotation direction of the docking mechanism 10 is adjusted by the adjustment mechanism 50, so as to facilitate the transfer operation of the air-conditioning outer case in three directions. When the height of the transfer platform cannot match the height of the docking mechanism 10, the rotation angle of the conveyor belt 20 can be adjusted by the electric push rod 80. When the rotation angle of the conveyor belt 20 is adjusted, the conveying rate of the conveyor belt 20 itself changes accordingly, which can ensure that the air-conditioning outer case is smoothly transferred to the conveyor belt 20 via the docking mechanism 10, thereby reducing the quality of the air-conditioning outer case transportation and reducing the probability of damage to the air-conditioning outer case during transportation.

[0029] The docking mechanism 10 includes a shell 11 fixed to the adjustment mechanism 50 and two spiral conveying rollers 14, both long sides of the shell 11 are fixed with connecting arms 12, and a cross bar 13 connected to the shell 11 is fixed between the two ends of the two connecting arms 12, and the top surface of the shell 11 is symmetrically provided with two through holes, and the two spiral conveying rollers 14 are symmetrically arranged inside the shell 11 and rotatably connected thereto, and a strip through hole 111 is provided at one end of the bottom plate 30 of the shell 11, and two first motors 15 are installed at the bottom of the shell 11, and a linkage belt 151 is sleeved between the motor shafts of the two first motors 15 and the end of an adjacent spiral conveying shaft, and the two symmetrically distributed spiral conveying rollers 14 are driven to rotate by the two first motors 15 respectively, and the differential motion between the two spiral conveying rollers 14 can make the air conditioner outer case thereon transfer to three directions, so as to facilitate the selection of the docking direction according to the relative position between the production line and the transfer platform, thereby improving the efficiency of docking and transfer.

[0030] The adjustment mechanism 50 includes a rotating drum 52, a second motor 53, a driving gear 54 and a driven gear ring 55. The rotating drum 52 is rotatably connected to the bottom plate 30. The driven gear ring 55 is sleeved and fixed to the outer side of the bottom of the rotating drum 52. The driven gear ring 55 is meshed with the driving gear 54. The top surface of the bottom plate 30 is located on the outer side of the rotating drum 52 and a bottom cover 51 is fixed thereto. The second motor 53 is installed on the top surface of the bottom cover 51 at a position corresponding to the driving gear 54. The motor shaft of the second motor 53 passes through the bottom cover 51 and is fixed to the driving gear 54. The top plate of the rotating drum 52 is fixedly clamped with a hydraulic cylinder 56, and the output end of the hydraulic cylinder 56 is fixedly connected to the shell 11. The second motor 53 is used to drive the driving gear 54 to rotate, and then the driven gear ring 55 engaged with it can drive the rotating drum 52 to rotate accordingly, and then can drive the docking mechanism connected to it through the hydraulic cylinder 56 to rotate synchronously, so as to adjust the direction of the docking mechanism 10. The hydraulic cylinder 56 can be used to first adjust the height of the docking mechanism 10 and then rotate it, so as to ensure that the docking mechanism 10 is still in a relative position with the conveyor belt 20 when adjusting the docking direction.

[0031] The conveyor belt 20 includes a conveyor frame 21 and a transmission belt 22, both ends of the conveyor frame 21 are rotatably connected with a first rotating roller 23, and the conveyor frame 21 is symmetrically rotatably connected with two second rotating rollers 24 located between the two first rotating rollers 23, the transmission belt 22 is rotatably sleeved on the two first rotating rollers 23, the two second rotating rollers 24 and the outer side of the driving roller 70, and the driving roller 70 is rotatably connected to the conveyor frame 21, and the end of the vertical plate 40 away from the docking mechanism 10 is provided with a first arc-shaped through hole 41, and both ends of a first rotating roller 23 adjacent to the first arc-shaped through hole 41 pass through the first arc-shaped through hole 41 at the corresponding position, and the two ends of the other first rotating roller 23 are respectively connected to the first arc-shaped through hole 41. The adjacent vertical plates 40 are rotationally connected, and the fixed end of the electric push rod 80 is rotationally connected to one side of the vertical plate 40. The output end of the electric push rod 80 is rotationally sleeved on one end of the adjacent first rotating roller 23. The speed regulating mechanism 60 can drive the driving roller 70 to rotate, thereby driving the transmission belt 22 connected to the driving roller 70 to rotate synchronously. When the height of the transfer platform cannot match the height of the docking mechanism 10, the electric push rod 80 drives a first rotating roller 23 adjacent to it to move downward, so that the entire conveying frame 21 can rotate around the other first rotating roller 23 as the axis, so that it can be suitable for the situation where the height of the transfer platform is lower than the docking mechanism 10, which is beneficial to improve the efficiency of docking and transfer.

[0032] A notch 43 is formed on one side of the vertical plate 40 adjacent to the docking mechanism 10 . The notch 43 is located below the docking mechanism 10 . The notch 43 can prevent the vertical plate 40 from obstructing the adjustment mechanism 50 from driving the docking mechanism 10 to turn.

[0033] A second arc-shaped through hole 42 is opened in the middle of one of the vertical plates 40, and one end of the driving roller 70 passes through the second arc-shaped through hole 42 and extends to the outside of the vertical plate 40. The speed regulating mechanism 60 includes a third motor 61, a pulley 62, a steel belt 63, a fixed cone disc 64 and a movable cone disc 65. A mounting frame is fixed to one side of the third motor 61, and the mounting frame is fixed to an adjacent vertical plate 40. The pulley 62 is fixedly sleeved on the motor shaft of the third motor 61. The fixed cone disc 64 and the movable cone disc 65 are both sleeved on the outer cylindrical surface of one end of the driving roller 70, wherein the The fixed cone disc 64 is fixedly sleeved on the driving roller 70, the movable cone disc 65 is slidably sleeved on the driving roller 70, the steel belt 63 is rotatably sleeved between the pulley 62 and the fixed cone disc 64 and the movable cone disc 65, the driving roller 70 is located at one end of the outer side of the vertical plate 40 and fixed with a limit plate 67, and a compression spring 66 is fixed between one side of the limit plate 67 and one side of the movable cone disc 65. When the height of the transfer platform is lower than the docking mechanism 10, the output end of the electric push rod 80 contracts, so that the first rotating roller 23 adjacent to it moves downward along the first arc-shaped through hole 41, so that the output The conveying belt 20 is tilted, and at the same time, the driving roller 70 adjacent to the conveying frame 21 moves down along the second arc-shaped through hole 42, so that the distance between the driving roller 70 and the pulley 62 increases. At this time, the edge of the steel belt 63 squeezes the fixed cone disk 64 and the movable cone disk 65, pushing the two away from each other, and then compresses the compression spring 66. Under the action of the third motor 61, the linear speed of the pulley 62 does not change, the overall length of the steel belt 63 remains unchanged, and the angular velocity at the driving roller 70 increases, so that the rotation rate of the driving roller 70 is accelerated, and then the transmission belt 22 can be driven to accelerate. 4 The speed of transferring the air-conditioning outer case does not change. When the conveyor belt 20 is tilted, when one end of the air-conditioning outer case is tilted to contact the conveyor belt 20, under the action of the continuous thrust of the spiral conveying roller 14, and when the conveyor belt 20 maintains the same conveying speed as the spiral conveying roller 14, it is easy to accelerate the air-conditioning outer case to the conveyor belt 20, which is easy to cause the air-conditioning outer case to shake and fall. The transmission belt 22 that is accelerated after tilting and the bottom surface of the air-conditioning outer case are used to collide with each other, thereby realizing the action of pulling the air-conditioning outer case to the conveyor belt 20, thereby improving the efficiency of the smooth transfer of the connection position between the two.

[0034] The fixed cone disk 64 is directly opposite to the small end of the movable cone disk 65, and can ensure that the linear speed of the driving roller 70 driven by the steel belt 63 changes accordingly when the inclination angle of the conveyor belt 20 changes. The compression spring 66 is movably sleeved on the outer side of one end of the driving shaft. The horizontal plane where the top end of the spiral conveying roller 14 is located is flush with the top surface of the connecting arm 12, and the spiral patterns on the two spiral conveying rollers 14 rotate in opposite directions. This can ensure that the air-conditioning outer case can be easily moved out of the docking mechanism position when it is transferred in three directions.

[0035] Working principle: When in use, a controller can be installed on the bottom plate 30, and the controller can be used to control the start and stop of the motor, the electric push rod 80 and the hydraulic cylinder 56, and the docking conveyor line can be arranged at an appropriate position. According to the size of the site and the position to be transferred, the adjustment mechanism 50 can be used to adjust the rotation direction of the docking mechanism 10 so that it is directly opposite to the transfer platform. When the docking mechanism 10 and the transfer platform are at the same height, the conveyor belt 20 is at the same height as the two, which is convenient for use when the transfer platform position and the production line exit position cannot be directly opposite;

[0036] When the height of the docking mechanism 10 is higher than the transfer platform, the output end of the electric push rod 80 contracts, so that the first rotating roller 23 adjacent to it moves down along the first arc-shaped through hole 41, so that the conveyor belt 20 is tilted. At the same time, the driving roller 70 adjacent to the conveying frame 21 moves down along the second arc-shaped through hole 42, so that the distance between the driving roller 70 and the pulley 62 increases. At this time, the edge of the steel belt 63 squeezes the fixed cone disk 64 and the movable cone disk 65, pushing the two away from each other, and then compressing the compression spring 66. Under the action of the third motor 61, the linear speed of the pulley 62 does not change, the overall length of the steel belt 63 remains unchanged, and the angular velocity at the driving roller 70 becomes larger, so that the rotation rate of the driving roller 70 is accelerated, which can It is enough to drive the transmission belt 22 to accelerate. Since the speed of the spiral conveyor roller 14 when transferring the air-conditioning outer case does not change, when the conveyor belt 20 is tilted, when one end of the air-conditioning outer case is tilted to contact the conveyor belt 20, under the action of the continuous thrust of the spiral conveyor roller 14 and when the conveyor belt 20 maintains the same conveying speed as the spiral conveyor roller 14, it is easy to accelerate the air-conditioning outer case to the conveyor belt 20, which may easily cause the air-conditioning outer case to shake and fall. The transmission belt 22 that is accelerated after tilting and the bottom surface of the air-conditioning outer case are used to collide with each other, thereby realizing the action of pulling the air-conditioning outer case to the conveyor belt 20, ensuring the stable transportation of the air-conditioning outer case. After the conveyor belt 20 is reset, the compression spring 66 pushes the movable cone 65 to reset.
