[0032] (Example 1)

[0033] like Figures 1 to 2 The fully automatic bucket frame guide spacing adjustment mechanism shown includes a vertical plate 1, a horizontal plate 2, a lifting mechanism 3, a Y-axis adjustment mechanism 4 and an X-axis adjustment mechanism 5, wherein two vertical plates 1 are provided opposite to each other, two Y-axis adjustment mechanisms 4 are also provided and are respectively installed on the inner sides of the two vertical plates 1 through the lifting mechanism 3, two horizontal plates 2 are provided in parallel and connected between the two vertical plates 1 through the Y-axis adjustment mechanism 4, and multiple mounting rods 6 are provided in parallel between the two horizontal plates 2. The mounting rods 6 are adjustably mounted on the horizontal plates 2 through the X-axis adjustment mechanism 5. The middle part of each mounting rod 6 is fixed with a first guide plate, and the two ends are provided with a second guide plate that moves synchronously with the horizontal plates 2, thereby forming a carton guide bucket frame between adjacent mounting rods. The Z-axis, Y-axis and X-axis directions of the mounting rods 6 are adjusted by the lifting mechanism 3, the Y-axis adjustment mechanism 4 and the X-axis adjustment mechanism 5, respectively, so that the guide spacing of the bucket frame can be flexibly and automatically adjusted according to the size of the carton, saving time and effort.

[0034] Specifically, the lifting mechanism 3 includes a chain drive assembly mounted on the inner sides of the two vertical panels 1. The chain drive assembly includes a driving wheel 3-1, a driven wheel 3-2, and a chain 3-3 that surrounds the driving wheel 3-1 and the driven wheel 3-2. On some equipment, a transition wheel 3-4 may be added to the chain drive to avoid any movement, thereby changing the transmission direction. The driving wheel 3-1 is rotatably mounted on the vertical panel 1. A tensioning plate 3-5 is connected between the driven wheel 3-2 and the vertical panel 1. The driven wheel 3-2 is rotatably mounted on the tensioning plate 3-5. The vertical panel 1 is provided with a strip groove extending in the vertical direction. The tensioning plate 3-5 is adjustably mounted on the vertical panel 1 by bolts passing through the strip groove and locked. This allows for adjustment of the transmission spacing, ensuring chain tension and preventing chain derailment. Connected between the two chain drive assemblies is a transmission shaft 3-8 rotatably mounted between the two vertical panels 1. Two driving pulleys 3-1 are coaxially fixed to the transmission shaft 3-8. A lifting frame 3-6 is fixedly connected to the chain 3-3. A first drive motor 3-7, coaxially connected to the transmission shaft 3-8, is fixedly mounted on one of the vertical panels 1. The first drive motor 3-7 rotates the transmission shaft 3-8, thereby driving the lifting frames 3-6 at both ends through the two chain drive assemblies for lifting and lowering. To enhance the stability of the lifting motion, this embodiment includes symmetrically arranged first linear guides 7 longitudinally disposed on the vertical panels 1. A first slider 8 is provided on the first linear guides 7. The lifting frames 3-6 are fixedly connected to the first slider 8, providing both guidance and support.

[0035] The Y-axis adjustment mechanism 4 includes a support frame 4-1, a forward and reverse threaded screw 4-2, a second drive motor 4-3 and a moving block 4-4. The support frame 4-1 is a rectangular frame composed of four strip plates, which is fixed to the bottom of the lifting frame 3-6. A support plate is vertically fixed between the two long sides of the rectangular frame to improve the overall structural strength of the support frame 4-1. The forward and reverse threaded screw 4-2 is rotatably mounted on the support frame 4-1 and extends along the Y-axis direction. The second drive motor 4-3 is fixed to the side of the support frame 4-1 and is coaxially fixed to the forward and reverse threaded screw 4-2. There are two moving blocks 4-4, which are respectively threadedly mounted on the forward and reverse thread intervals of the forward and reverse threaded screw 4-2. The second drive motor 4-3 drives the forward and reverse threaded screw 4-2 to rotate to realize the two moving blocks 4-4 approaching or moving away from each other. The two ends of the two horizontal plates 2 are respectively fixed to the corresponding moving blocks 4-4 to achieve synchronous movement. To improve the stability of movement in the Y-axis direction, guide rods 9 are installed parallel to the upper and lower sides of the forward and reverse threaded screw rods 4-2 of this embodiment, and the moving block 4-4 slides in cooperation with the guide rods 9. In this embodiment, a position pointer 10 is fixed to the upper end of the moving block 4-4, and limit pointers 11 corresponding to the position pointer 10 are provided at both ends of the support frame 4-1. They serve as servo reference points during debugging to facilitate operation.

[0036] Mounting plates 12 are sleeved on both ends of the mounting rod 6. A second guide plate is fixedly mounted on the mounting plate 12, and moves along the Y direction with the cross plate, and moves along the X direction by following the mounting rod. The X-axis adjustment mechanism 5 includes a third motor 5-1 fixedly mounted on the mounting plate 12, a gear 5-2 fixedly connected to the output shaft of the third motor 5-1, and a rack 5-3 mounted on the outside of the cross plate 2. The gear 5-2 meshes with the rack 5-3, thereby driving the mounting rod 6 along the X-axis direction under the drive of the third motor 5-1. To improve movement stability, this embodiment has a second linear guide 13 fixedly mounted on the cross plate 2, arranged parallel to the rack 5-3. A plurality of second sliders 14 corresponding to the mounting plates 12 are slidably provided on the second linear guide 13, and the mounting plates 12 are fixedly mounted on the corresponding second sliders 14. In addition, a limit portion 6-1 is provided at both ends of the mounting rod 6, and a spring 15 sleeved on the mounting rod 6 is connected between the limit portion and the mounting plate 12, which can not only serve as a buffer for movement to the extreme position in the Y-axis direction, but also ensure that during the entire Y-axis adjustment process, each mounting rod always remains centered in the Y-direction, so that the second guide plate is always located in the middle of the first guide plates at both ends.

[0037] This embodiment uses a lifting mechanism, a Y-axis adjustment mechanism and an X-axis adjustment mechanism to adjust the Z-axis, Y-axis and X-axis directions of the mounting rod respectively, so that the guide spacing of the bucket frame can be flexibly and automatically adjusted according to the size of the carton, saving time and effort.
