Description

Technical Field

[0001] The utility model relates to the technical field of rectifying equipment, in particular to a cardboard rectifying machine. Background Technique

[0002] Cardboard is a thick paper sheet made of various pulp and composed of interwoven fibers, including packaging cardboard, industrial technical cardboard, and building cardboard. Among them, packaging cardboard is often embodied in the form of corrugated paper. During the production process of cardboard, a conveying device is needed to convey the cardboard. During the conveying process of the cardboard, it may deviate. If the cardboard deviates, it will cause the position deviation during the later processing station of its conveying, resulting in inaccurate later processing. Therefore, a rectifying machine is needed to rectify the cardboard on the conveying device.

[0003] In order to improve the stability of cardboard conveying, many improvements have been made to cardboard rectifying machines in the prior art. For example, the patent with the patent publication number CN216471328U discloses a cardboard rectifying mechanism, including a main body of the conveying device. A plurality of transmission shafts are arranged at the upper end of the main body of the conveying device, and rectifying mechanisms are arranged on both side sections at the upper end of the main body of the conveying device. For the cardboard rectifying mechanism described in the utility model, before the device operates, the whole rectifying mechanism is first installed on the upper end of the main body of the conveying device through two fixing mechanisms. For cardboard of different sizes, first place the cardboard between two clamping plates. The staff rotates the double-headed stud at the upper ends of the two clamping plates. At this time, the two clamping plates slide relative to each other based on the limiting grooves. The two pitches of the two sections of the double-headed stud are the same. Therefore, as the double-headed stud rotates, the two clamping plates slide relative to each other based on the limiting grooves by the same distance to achieve the centered conveying of the cardboard. Wait until the two clamping plates fit to both sides of the cardboard, then the preset can be achieved. The practicability of the rectifying mechanism is relatively high, bringing a better application prospect.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the two clamping plates are driven to move towards or away from each other by rotating the double-headed stud to rectify the cardboard conveyed on the conveying device. In actual operation, in the above comparative document, the rectifying mechanisms are installed at intervals on the transmission device, and there is a certain distance between the rectifying mechanisms. Since many edges of the cardboard are right-angled, when the cardboard deviates during the transmission process, the right-angled edge of the cardboard may be blocked by the clamping plate. At this time, the deviation angle of the cardboard will increase, and even the cardboard will be stuck on the conveying device. It is necessary to manually align the cardboard stuck between the clamping plates to ensure the normal transmission of the subsequent cardboard, thereby reducing the transmission efficiency of the cardboard. Therefore, it is urgent to improve the cardboard rectifying machine in this field to solve the defects of the prior art. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 , a cardboard deviation rectifying machine, including two groups of deviation rectifying units 2 symmetrically installed on the upper part of the conveyor device 1. Each group of deviation rectifying units 2 includes two fixed plates 3. Vertical carrier plates 4 are provided on the upper sides of the two fixed plates 3. U-shaped fixed frames 5 are provided on the sides of the two carrier plates 4. A rotating shaft 6 is rotatably connected between the inner side walls of the two fixed frames 5. Driving rollers 7 are fixedly connected to the sides of the two rotating shafts 6. A transmission belt 8 is sleeved between the sides of the two driving rollers 7. A first adjusting unit for adjusting the horizontal position of the fixed frame 5 is provided between each fixed frame 5 and the carrier plate 4. A second adjusting unit for adjusting the height position of the fixed frame 5 is provided on each carrier plate 4. A third adjusting unit for adjusting the distance between the two carrier plates 4 on the same side is provided on each fixed plate 3. Driving motors 9 are provided on the upper sides of several fixed frames 5. The output end of the driving motor 9 is fixedly connected to one end of the rotating shaft 6. A bearing body 21 is sleeved on the lower side of the rotating shaft 6. The lower side of the transmission belt 8 is in contact with the upper side of the bearing body 21.

[0028] Specific implementation manner in this embodiment: First, install two deviation rectifying units 2 on both sides of the upper part of the conveying device 1 respectively. Fix the fixing plate 3 on the conveying device 1 by welding or fastening bolts. Adjust the horizontal position of the fixing frame 5 through the first adjusting unit, adjust the distance between the two transmission belts 8 to be adapted to the cardboard. Adjust the height position of the fixing frame 5 through the second adjusting unit. The lower side surface of the transmission belt 8 is attached to the upper conveying surface of the conveying device 1. Adjust the distance between two bearing plates 4 on the same side through the third adjusting unit to make the transmission belt 8 taut. When the cardboard is conveyed on the conveying device 1, the cardboard is located between the two transmission belts 8, ensuring that the cardboard will not shift during conveyance. At the same time, the driving motor 9 can be started. The output end of the driving motor 9 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the transmission roller 7 to rotate, and the transmission roller 7 drives the transmission belt 8 to rotate. The rotation speed of the transmission belt 8 is adapted to the conveying speed of the conveying device 1, reducing the friction generated when the cardboard is conveyed, thereby improving the conveying efficiency of the cardboard. At the same time, when the transmission belt 8 rotates, the bearing body 21 rotates accordingly, preventing the transmission belt 8 from moving downward, reducing the friction and wear between the lower side wall inside the fixing frame 5 and the transmission belt 8, and improving the service life of the transmission belt 8. It should be noted that if the length of the conveying device 1 is long, multiple groups of deviation rectifying units 2 are installed adjacent to each other.

[0029] Among them, the above-mentioned driving motor 9 can be purchased on the market. It belongs to mature technology and has been fully disclosed. Therefore, it is not repeated in the specification. The driving motor 9 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V single-phase voltage (or 380V three-phase voltage) through the power cord. And the main controller can be a conventional known device such as a computer that plays a control role.

[0030] Embodiment Two

[0031] Please refer to Figure 3 and Figure 4 This embodiment includes the above-mentioned embodiment. Among them, the second adjusting unit includes a first sliding block 12 slidably connected in the bearing plate 4. Opposite side surfaces of the bearing plate 4 are penetrated with a first sliding groove 13 adapted to the first sliding block 12. The upper end of the bearing plate 4 is rotatably connected with a first adjusting rod 14 whose one end extends to the inner bottom of the first sliding groove 13. The first adjusting rod 14 penetrates through the first sliding block 12 and is threadedly connected with the first sliding block 12. A first limiting nut 15 for limiting and fixing the first adjusting rod 14 is threadedly connected to the upper side surface of the first adjusting rod 14. The first adjusting unit includes an adjusting bolt 10 rotatably connected to one side of the fixing frame 5. The adjusting bolt 10 horizontally penetrates through the first sliding block 12 and is threadedly connected with the first sliding block 12. A limiting ring 11 for limiting and fixing the adjusting bolt 10 is threadedly connected to the side surface of the adjusting bolt 10. A guiding and limiting column 20 is fixedly connected to one side of the fixing frame 5. The guiding and limiting column 20 horizontally penetrates through the first sliding block 12.

[0032] Specific implementation manner in this embodiment: After the fixing plate 3 is installed, it is necessary to adjust the position of the transmission belt 8 according to the size of the actual conveying device 1 and the cardboard. By rotating the adjusting bolt 10, the horizontal position of the fixing frame 5 can be adjusted, and the distance between the two transmission belts 8 is adjusted to a position adapted to the cardboard to be conveyed. When the horizontal position of the fixing frame 5 moves, the guiding and limiting column 20 moves on the first sliding block 12. The cross section of the guiding and limiting column 20 is rectangular to limit the position of the fixing frame 5, and the position of the adjusting bolt 10 is limited and fixed by tightening the limiting ring 11. When it is necessary to adjust the height position of the transmission belt 8, by rotating the first adjusting rod 14, when the first adjusting rod 14 rotates, it drives the first sliding block 12 to move in the first sliding groove 13. The first sliding block 12 drives the adjusting bolt 10 to move, and then drives the fixing frame 5 to move in the height direction, and the lower side surface of the transmission belt 8 is adjusted to be in contact with the upper side surface of the conveying device 1 to ensure the deviation correction effect on the cardboard, and the position of the first adjusting rod 14 is limited and fixed by tightening the first limiting nut 15.
