Description

Technical Field

[0001] This utility model relates to the technical field of book packaging, specifically to a spacing adjustment mechanism between the upper and lower acceleration wheels of a book separating device. Background Technology

[0002] High-speed book sorting device is an important component of automatic book dispensing equipment. Its function is to distribute individual books to the book stacking channel, and then use the book stacking channel to stack the individual books and transport them to the next station. Therefore, high-speed book sorting device is quite important.

[0003] Current high-speed book sorting devices, such as the high-speed automatic book dispensing device disclosed in patent application number 201721626676.7, generally include a hopper for placing and storing books, a pushing mechanism for pushing the books out of the hopper, and a book sorting outlet for exiting the books from the hopper. The hopper consists of a rear baffle, side baffles, a front baffle, and a suction-type book sorting platform. The suction-type book sorting platform is connected to the pushing mechanism and is equipped with a book sorting push plate. An acceleration mechanism is located at the book sorting outlet. This includes upper and lower acceleration wheels positioned vertically. The gap between the upper and lower acceleration wheels can be adjusted by adjusting the swing arm to allow a single book to pass through. However, the current method of adjusting the swing arm requires adjusting both sides of the swing arm simultaneously to synchronously adjust the height of the entire swing arm and ultimately adjust the distance between the upper and lower acceleration wheels. This method is prone to issues such as incomplete adjustment on both sides, resulting in a tilted gap between the upper and lower acceleration wheels. Furthermore, it is inconvenient to adjust and therefore needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a gap adjustment mechanism between the upper and lower acceleration wheels of a book-separating device to solve the problems mentioned in the background art, such as the inability to adjust the gap between the upper and lower acceleration wheels on both sides, resulting in a tilting problem in the gap between the upper and lower acceleration wheels, and the inconvenience of adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gap adjustment mechanism for the upper and lower acceleration wheels of a book-separating device, comprising a frame, a book-separating outlet on the side of the frame, an acceleration mechanism at the book-separating outlet, the acceleration mechanism comprising an upper acceleration wheel and a lower acceleration wheel arranged vertically, the lower acceleration wheel being rotatably connected to the frame via a transmission shaft, an adjustment assembly being provided above the book-separating outlet, the adjustment assembly comprising an adjustment arm, two longitudinally distributed guide rails, a mounting seat, a positioning seat, and a second transmission shaft, the two guide rails being fixed to the frame, the adjustment arm being slidably connected between the two guide rails, a guide rod being fixed on each side of the adjustment arm, a mounting seat being connected below each guide rod, and a positioning seat being fixed below each mounting seat, the two ends of the second transmission shaft being rotatably connected to the positioning seats respectively, the upper acceleration wheel being mounted on the second transmission shaft, an adjustment screw being threadedly connected to the frame, the lower end of the adjustment screw being connected to the adjustment arm, and an adjustment wheel being provided at the upper end of the adjustment screw.

[0006] Furthermore, in order to ensure the flexible setting of the distance between the upper and lower acceleration wheels, each guide rod is fitted with a spring whose upper end abuts against the bottom of the adjusting arm and whose lower end abuts against the top of the mounting base.

[0007] Furthermore, in order to further guide the mounting base as it slides up and down and prevent positional deviation during movement, a guide groove is provided on both sides of the book outlet, and the mounting base is slidably connected in the guide groove.

[0008] Furthermore, two lower acceleration wheels are respectively provided on the first transmission shaft, and two upper acceleration wheels are respectively provided on the second transmission shaft, with each upper acceleration wheel corresponding to one lower acceleration wheel.

[0009] Furthermore, to ensure that the distance between the two lower acceleration wheels is adjustable, two waist-shaped groove holes are provided on the transmission shaft, extending along the length of the transmission shaft. A through hole is provided on the side of the lower acceleration wheel, which is aligned with the waist-shaped groove hole. A locking screw is inserted into the through hole and threadedly connected to the waist-shaped groove hole.

[0010] Furthermore, to ensure that the distance between the two upper acceleration wheels is adjustable, two waist-shaped groove holes are provided on the transmission shaft two, extending along the length direction of the transmission shaft two. The side of the upper acceleration wheel is provided with a through hole two aligned with the waist-shaped groove hole two. A locking screw two is inserted into the through hole two and threadedly connected to the waist-shaped groove hole two.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this structure can stably adjust the adjusting arm by simply rotating the adjusting screw. Compared with the method of manually adjusting both sides of the adjusting arm simultaneously, the adjustment of this structure is more stable, and the adjustment height on both sides can be kept consistent.

[0020] Example 1

[0021] Please see Figures 1-5 As shown in this embodiment, a distance adjustment mechanism for the upper and lower acceleration wheels of a book-separating device includes a frame 1. A book-separating outlet 2 is provided on the side of the frame 1. An acceleration mechanism is located at the book-separating outlet 2, comprising an upper acceleration wheel 3 and a lower acceleration wheel 4 arranged vertically. The lower acceleration wheel 4 is rotatably connected to the frame 1 via a drive shaft 5. An adjustment assembly is also provided above the book-separating outlet 2. The adjustment assembly includes an adjustment arm 6, two longitudinally distributed guide rails 7, a mounting base 8, a positioning base 9, and a drive shaft 10. The two guide rails 7 are fixed to the frame 1, and the adjustment arm 6 is slidably connected between the two guide rails 7. A guide rail is fixed on each side of the adjustment arm 6. Each guide rod 11 has a mounting base 8 connected to its lower end, and a positioning base 9 is fixed to the lower end of each mounting base 8. The two ends of the transmission shaft 10 are rotatably connected to the positioning base 9. The upper acceleration wheel 3 is mounted on the transmission shaft 10. An adjusting screw 12 is also threaded onto the frame 1. The lower end of the adjusting screw 12 is connected to the adjusting swing arm 6, and the upper end of the adjusting screw 12 is provided with an adjusting wheel 13. In order to further guide the mounting base 8 when it slides up and down and avoid positional deviation during movement, a guide groove 21 is provided on both sides of the book outlet 2. The mounting base 8 is slidably connected in the guide groove 21.

[0022] Furthermore, in order to ensure the flexible setting of the distance between the upper acceleration wheel 3 and the lower acceleration wheel 4, each guide rod 11 is fitted with a spring 14, the upper end of which abuts against the bottom of the adjusting arm 6 and the lower end of which abuts against the top of the mounting base 8. By adding the spring 14, the connection between the positioning base 9 and the adjusting arm 6 is made elastic, thus ensuring the flexible setting of the distance between the upper acceleration wheel 3 and the lower acceleration wheel 4 and preventing the notebook from being damaged by the hard contact between the upper acceleration wheel 3 and the lower acceleration wheel 4.

[0023] In this embodiment, two lower acceleration wheels 4 are respectively arranged on the first transmission shaft 5, and two upper acceleration wheels 3 are respectively arranged on the second transmission shaft 10, with each upper acceleration wheel 3 corresponding to one lower acceleration wheel 4, ensuring that the distance between the two lower acceleration wheels 4 and the distance between the upper acceleration wheels 3 are adjustable. Two waist-shaped groove holes 15 extending along the length direction of the first transmission shaft 5 are provided on the first transmission shaft 5. The side of the lower acceleration wheel 4 is provided with a through hole 16 aligned with the waist-shaped groove hole 15, and a screw thread is inserted into the through hole 16 to be threaded into the waist-shaped groove hole 15. The locking screw 17 is connected by a thread. Two waist-shaped groove holes 18 are provided on the transmission shaft 10, extending along the length of the transmission shaft 10. The side of the upper acceleration wheel 3 is provided with a through hole 19 aligned with the waist-shaped groove hole 18. A locking screw 20 is inserted into the through hole 19 and threadedly connected to the waist-shaped groove hole 18. During operation, according to the installation requirements, the corresponding acceleration wheel is first slid to the appropriate position, and then the corresponding locking screw passes through the corresponding through hole and is threadedly locked with the corresponding waist-shaped groove hole. This structure can transport notebooks of different widths.

[0024] The adjustment method of this structure is as follows: By rotating the adjusting wheel 13 by hand, the adjusting screw 12 rotates, which in turn drives the entire adjusting arm 6 to move up and down. During the movement, the entire transmission shaft 10 below moves up and down along the frame 1, ultimately adjusting the distance between the upper acceleration wheel 3 and the lower acceleration wheel 4 by moving the upper acceleration wheel 3 up and down. Therefore, this structure can stably adjust the adjusting arm 6 by simply rotating the adjusting screw 12. Compared with the method of adjusting both sides of the adjusting arm 6 simultaneously, the adjustment of this structure is more stable, and the adjustment height on both sides can be kept consistent.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
