Description

Technical Field

[0001] The present application relates to the field of cardboard processing equipment, and in particular to an angle-adjustable cardboard blanking device. Background Art

[0002] In the modern printing industry, various automated equipment is widely used in production lines to improve production efficiency and product quality. The stacking of printed cardboard is a crucial step, directly impacting subsequent workflows and product quality control. Therefore, optimizing this process not only improves efficiency but also reduces worker workload, ensuring continuous and stable production.

[0003] After printing, conventional cardboard is typically transported to a designated location via a fixed conveyor system, where it is then manually stacked and sorted. These conveyor systems primarily include chain drives, belt conveyors, and roller conveyors. Chain drives are suitable for transporting heavier items, while belt conveyors are more suitable for the smooth movement of lighter items. Roller conveyors are also widely used due to their increased flexibility.

[0004] However, in actual use, traditional fixed conveyor systems have proven inconvenient when handling larger cardboard sheets, as they lack the ability to adjust their angles. This is particularly true for large sheets that require adjustment, as the fixed, flat conveyor system often makes it difficult for workers to efficiently stack them, increasing the complexity and physical strain of the work. Utility Model Content

[0005] In order to reduce the difficulty of stacking cardboard after printing, the present application provides an angle-adjustable cardboard blanking device.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiment of the present application discloses an angle-adjustable cardboard blanking device. Figure 1 and Figure 2The angle-adjustable cardboard unloading device includes a frame 1, on which a transmission component 2 is provided for transmitting the cardboard from one side of the printing device 4 to the other side; the frame 1 is also provided with a lifting component 3, which controls the lifting and lowering of the end of the transmission component 2 away from the printing device 4, thereby changing the angle of the transmission component 2, thereby reducing the difficulty of stacking the cardboard after printing.

[0028] Reference Figure 1 and Figure 2 Frame 1 consists of a base, columns, and a top beam. The base is welded from steel plates and is strong enough to support the entire unit. The columns are made of high-strength steel and welded vertically to the base to support the top beam. The top beam spans the tops of the two columns, providing a connection. The load-bearing capacity of the columns can be increased by increasing their wall thickness or selecting higher-quality steel. For example, reinforcing them with H-shaped steel or stiffened plates will provide them with better bending resistance.

[0029] Multiple universal wheels 12 are provided at the bottom of the frame 1. Each universal wheel 12 is mounted on the bottom of the frame 1, and its mounting base is bolted to the bottom of the frame 1. The universal wheels 12 are made of a high-strength, wear-resistant material. The diameter of the universal wheels 12 is selected based on the thickness of the frame 1 and the required load to ensure smooth movement of the equipment.

[0030] Reference Figure 1 and Figure 2 The transmission assembly 2 comprises a transmission frame 21 and several transmission belts 22. The end of the transmission frame 21 closest to the printing device 4 is rotatably connected to the frame 1 via a shaft. The lifting assembly 3 controls the lifting of the end of the transmission frame 21 away from the printing device 4. Several transmission belts 22 are mounted in parallel on the transmission frame 21, moving away from the printing device 4. Each belt 22 is approximately 30 cm wide and made of wear-resistant rubber. A tensioning device is installed underneath the transmission belts 22 to ensure smooth transmission without slippage.

[0031] The transmission frame 21 is provided with a number of support rods 23. The support rods 23 can be fixed to the transmission frame 21 by welding or threaded connection to ensure a firm connection between the support rods 23 and the transmission frame 21. The support rods 23 are made of high-strength steel to ensure the stability and strength of the structure. The support rods 23 are arranged in parallel along the installation direction of the conveyor belt 22. Each support rod 23 supports a conveyor belt 22. In this embodiment, there is a gap between the support rods 23 and the conveyor belt 22. The gap is less than 1 cm, so that it is difficult for the support rods 23 to rub against the conveyor belt 22 during operation. At the same time, when the conveyor belt 22 is under pressure, the support rods 23 can provide timely support to the conveyor belt 22 to reduce the pulling of the conveyor belt 22.

[0032] A support frame 24 is installed at the end of the transport frame 21 away from the printing device 4. The support frame 24 is secured to the transport frame 21 with rivets or bolts to ensure its stability. The support frame 24 is able to contact the ground when the transport frame 21 changes angle. Made of high-strength aluminum alloy, the support frame 24 ensures stable contact with the ground during cardboard transport.

[0033] Reference Figure 1 and Figure 2 The lifting assembly 3 includes a lifting cylinder 31 and a connecting plate 32. One end of the lifting cylinder 31 is hinged to the frame 1, and the other end is hinged to the connecting plate 32. The connecting plate 32 is fixed to the bottom of the transmission frame 21 by bolts. The piston rod diameter of the lifting cylinder 31 can be selected in different specifications according to the load requirements. Commonly used diameters include 50mm, 70mm and other types. The connecting plate 32 is welded to the bottom of the transmission frame 21, and a wear-resistant material pad is used at the connection with the piston rod of the lifting cylinder 31 to extend the service life. In addition, the connecting plate 32 can also adopt a variety of structural forms, such as L-shape, T-shape, etc., to better adapt to the needs of different occasions.

[0034] The piston rod of the lifting cylinder 31 extends out of the cylinder body to set the transfer frame 21 horizontally. The piston rod of the lifting cylinder 31 retracts to one end of the cylinder body to lead the transfer frame 21 away from the printing device 4 to descend, thereby causing the entire transfer frame 21 to rotate along the axis. When the support frame 24 contacts the ground, the angle adjustment of the transfer frame 21 is completed.

[0035] Protective nets 11 are installed on both sides of the frame 1. These are composed of a stainless steel mesh and an aluminum alloy frame, forming a protective area between them. The lifting cylinder 31 is installed within the protective area. Protective nets 11 effectively prevent accidental injuries. Above protective nets 11 is an inclined surface 111, which slopes away from the printing device 4, facilitating a smooth transition of paperboard and preventing jamming.

[0036] The implementation principle of an angle-adjustable cardboard unloading device in an embodiment of the present application is as follows: the piston rod of the lifting cylinder 31 extends to the horizontal position of the transmission rack 21. At this time, the cardboard is transmitted from the printing device 4 and is transmitted to the tail end of the transmission rack 21 via the conveyor belt 22. The piston rod of the lifting cylinder 31 retracts to rotate the transmission rack 21. The support frame 24 is supported on the ground. Under the action of gravity, the cardboard slides along the inclined transmission rack 21 to the stacking rack pre-placed on the ground. The lifting cylinder 31 is used to control the angle of the transmission rack 21, and gravity is used to make the cardboard move smoothly to the stacking rack, thereby reducing the difficulty of stacking the cardboard neatly after printing.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
