Description

Technical Field

[0001] This utility model relates to the field of cardboard box slotting machine technology, specifically a cardboard box slotting machine that can avoid deviation. Background Technology

[0002] Cardboard boxes are packaging products made from cardboard through processes such as die-cutting, creasing, stapling, or gluing. Due to their superior performance and good processing properties, cardboard boxes have gradually replaced wooden boxes and other transport packaging containers, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also beautify and promote goods. Moreover, cardboard boxes are considered green and environmentally friendly products. During the production process, cardboard box slotting machines are used to slot the cardboard to improve production efficiency and meet packaging design requirements. The machine mainly includes a paper feeding section, a slotting section, and a printing section.

[0003] Currently, existing cardboard slotting machines use a conveyor belt to transport cardboard to the slotting area, where slotting is then performed by the slotting cutter. However, during this process, the cardboard on the conveyor belt is prone to shifting due to fluctuations in the conveyor belt speed, resulting in inaccurate slotting positions. This not only increases the scrap rate but also reduces production efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a carton slotting machine that can avoid misalignment, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carton slotting machine that can avoid deviation, comprising a frame and a conveyor belt, a top frame is provided at the top of the frame, a hydraulic cylinder is installed inside the top frame, and the bottom end of the hydraulic cylinder is connected to the slotting knife assembly, a limiting mechanism is provided through the inside of the frame, the limiting mechanism includes a drive motor, a two-way lead screw, a threaded block and a limiting plate, the limiting plate is movably connected to the top of the frame, and the frame is connected to the conveyor belt;

[0006] An anti-deviation mechanism is provided through the inner side of the conveyor belt. The anti-deviation mechanism includes an anti-deviation wheel, a cross plate, a support shaft, a pulley group A, a pulley group B, a gear group, a rotary motor, and a mounting plate. The mounting blocks at both ends of the conveyor belt are rotatably connected to the support shaft through bearings. A cross plate is provided at the top of the support shaft, and an anti-deviation wheel is rotatably connected to the bottom of the cross plate.

[0007] Preferably, an installation plate is provided on the inner side of the conveyor belt, a gear set is rotatably connected to the top of the installation plate via a bearing, and a rotary motor connected to the gear set via a coupling is installed at the bottom of the installation plate.

[0008] Preferably, two sets of support shafts are symmetrically arranged about the central axis of the mounting plate, and a pulley set A is sleeved on the outer side of the two sets of support shafts.

[0009] Preferably, the gear set and the two support shafts near the mounting plate are both fitted with pulley sets B, and pulley sets B are arranged perpendicular to pulley sets A. The gear set consists of a driving gear, a driven gear and a rotating shaft.

[0010] Preferably, a drive motor is installed at the front end of the frame, and the output end of the drive motor is connected to a bidirectional lead screw that is rotatably connected to the frame via a bearing through a coupling. The outer surface of the bidirectional lead screw is threaded with a threaded block that is connected to a limiting plate.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] A cardboard box slotting machine that can avoid misalignment, such as Figure 1 As shown, it includes a frame 1 and a conveyor belt 6. A top frame 2 is provided at the top of the frame 1. A hydraulic cylinder 3 is installed inside the top frame 2, and the bottom end of the hydraulic cylinder 3 is connected to the grooving knife group 4.

[0022] See Figure 1 It can be seen that after being limited by the limiting plate 504, the grooving knife group 4 can be controlled to move down by the hydraulic cylinder 3 so that the grooving knife group 4 can perform the grooving operation on the cardboard.

[0023] See Figure 1 and Figure 3 It is known that a limiting mechanism 5 is provided through the inside of the frame 1. The limiting mechanism 5 includes a drive motor 501, a bidirectional lead screw 502, a threaded block 503, and a limiting plate 504. The limiting plate 504 is movably connected to the top of the frame 1. The frame 1 is connected to the conveyor belt 6. The drive motor 501 is installed at the front end of the frame 1. The output end of the drive motor 501 is connected to the bidirectional lead screw 502, which is rotatably connected to the frame 1 through a bearing, via a coupling. The outer surface of the bidirectional lead screw 502 is threadedly connected to the threaded block 503, which is connected to the limiting plate 504.

[0024] See Figure 1 and Figure 3As can be seen, when the drive motor 501 is working, the output end of the drive motor 501 drives the bidirectional lead screw 502 to rotate. Since the threaded block 503 is threadedly connected to the bidirectional lead screw 502, and the guide block 506 is slidably connected to the guide rod 505, the threaded block 503 and the guide block 506 drive the two symmetrically arranged limiting plates 504 to move closer to the paperboard at the same time. Thus, the limiting plate 504 can be used to limit the paperboard, thereby preventing the paperboard from shifting during the grooving process.

[0025] See Figure 1 and Figure 2 It is known that an anti-deviation mechanism 7 is provided through the inner side of the conveyor belt 6. The anti-deviation mechanism 7 includes an anti-deviation wheel 701, a horizontal plate 702, a support shaft 703, a pulley set A 704, a pulley set B 705, a gear set 706, a rotary motor 707, and a mounting plate 708. The support shaft 703 is rotatably connected to the mounting blocks at both ends of the conveyor belt 6 via bearings. The top end of the support shaft 703 is provided with a horizontal plate 702, and the bottom end of the horizontal plate 702 is rotatably connected with the anti-deviation wheel 701. The mounting plate 708 is provided inside the conveyor belt 6, and the top end of the mounting plate 708 is provided through... A gear set 706 is rotatably connected to the bearing. A rotary motor 707 connected to the gear set 706 via a coupling is installed at the bottom end of the mounting plate 708. Two sets of support shafts 703 are symmetrically arranged about the central axis of the mounting plate 708. Pulley sets A704 are sleeved on the outer side of the two sets of support shafts 703. Pulley sets B705 are sleeved on the outer side of the gear set 706 and the two support shafts 703 near the mounting plate 708. Pulley sets B705 are arranged perpendicular to pulley sets A704. The gear set 706 consists of a driving gear, a driven gear, and a rotating shaft.

[0026] See Figure 1 and Figure 2 As can be seen, when the rotary motor 707 is working, the output end of the rotary motor 707 drives the gear set 706 to rotate. Since the support shaft 703 is linked with each other and with the gear set 706 through the pulley set A704 and pulley set B705 respectively, the two symmetrically arranged support shafts 703 rotate together. This allows the spacing of the two anti-deviation wheels 701 to be adjusted according to the cardboard size. The anti-deviation wheels 701 can be used to guide and prevent deviation of cardboard of different sizes, thereby preventing the cardboard from shifting when it moves from the conveyor belt 6 to the slotting area. This enables the carton slotting machine to prevent cardboard deviation from affecting the slotting accuracy, which not only reduces the scrap rate but also improves production efficiency and expands the scope of application.

[0027] See Figure 1 and Figure 3It is known that a guide block 506 is provided on the side of the limiting plate 504 away from the threaded block 503. A guide rod 505 connected to the frame 1 is provided through the inner side of the guide block 506, which can limit the limiting plate 504 and prevent the limiting plate 504 from shifting.

[0028] See Figure 1 It can be seen that the top of the frame 1 has five through slots that match the grooving knife group 4 at equal intervals, which can facilitate chip removal.

[0029] The working principle of this utility model is as follows: When using the carton slotting machine that can prevent deviation, the rotary motor 707 is started, causing the output end of the rotary motor 707 to drive the gear set 706 to rotate. Through the linkage between the support shafts 703 and between the support shafts 703 and the gear set 706, the two symmetrically arranged support shafts 703 rotate together, and the two support shafts 703 rotate in opposite directions. This allows the spacing between the two anti-deviation wheels 701 to be adjusted according to the size of the cardboard. At this time, the cardboard to be slotted is conveyed to the slotting area by the conveyor belt 6. During this process, the anti-deviation wheels 701 can be used to guide and prevent deviation of cardboard of different sizes, thereby preventing the cardboard from shifting off the conveyor belt 6. When the cardboard moves to the slotting area, it deviates. After the cardboard is conveyed to the slotting area, the drive motor 501 is started, so that the output end of the drive motor 501 drives the bidirectional lead screw 502 to rotate. Through the thread action of the threaded block 503 and the bidirectional lead screw 502, and the sliding action of the guide block 506 and the guide rod 505, the threaded block 503 and the guide block 506 drive the two symmetrically arranged limiting plates 504 to move closer to the cardboard at the same time. Thus, the limiting plate 504 can be used to limit the cardboard. At this time, the hydraulic cylinder 3 controls the slotting knife group 4 to move down so that the slotting knife group 4 can be used to perform the slotting operation on the cardboard.
