Technical Field

[0001] This utility model relates to the field of slitting devices, specifically a slitting device for cardboard processing. Background Technology

[0002] In the paperboard processing industry, the slitting process is a key step in dividing large-format paperboard into specific specifications. Paperboard slitting requires the use of paperboard slitting machines. There are many types of paperboard slitting machines available, but manual feeding slitting machines are still widely used because of their relatively low price. When using traditional manual feeding slitting machines, workers need to manually feed the paperboard at one end of the slitting machine. In order to pursue higher work efficiency, workers often take a lot of paperboard at a time and stack it on the feeding platform.

[0003] In actual operation, workers need to use one hand to support the bottom of the stacked cardboard and the other hand to move the top cardboard to feed it. Under long-term and high-intensity work conditions, the physical exertion of workers to support the cardboard is greater, which not only reduces work efficiency but also harms the health of workers. Therefore, a cardboard cutting device is proposed to address the above situation. Utility Model Content

[0004] To address the problem in existing technologies where workers must constantly use one hand to support the bottom of stacked cardboard while using the other to move the top layer of cardboard for feeding, resulting in greater physical exertion for workers during long hours and high-intensity work, this invention proposes a cardboard cutting device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a slitting device for cardboard processing, including a slitting machine, an adjustment mechanism and a protective mechanism. A feeding platform is fixed on the slitting machine, and a rectangular groove is opened on the feeding platform. A pallet for lifting the cardboard is rotatably connected to the rectangular groove.

[0006] The adjustment mechanism is installed on the rectangular groove and is used to adjust the tilt angle of the tray.

[0007] The protective mechanism is installed on the feeding platform and is used to protect the drive end of the adjustment mechanism.

[0008] Preferably, one end of the tray is fixedly connected to a rotating shaft, and both sides of the inner wall of the rectangular groove are provided with round holes, with the two ends of the rotating shaft respectively fitting with the round holes with clearance.

[0009] Preferably, the adjusting mechanism includes a threaded rod, one end of which is rotatably connected to the side of the inner wall of the rectangular groove. A threaded cylinder is threaded into the rectangular groove, and a first support rod is hinged to the top of the threaded cylinder. The other end of the first support rod is hinged to the bottom of the support plate. A drive shaft is fixedly connected to one end of the rectangular groove, and the drive shaft extends out of the rectangular groove.

[0010] Preferably, a guide rod is fixed on the rectangular groove, a sliding cylinder is fitted on the guide rod with clearance, a second support rod is hinged to the sliding cylinder, and the other end of the second support rod is hinged to the bottom of the support plate.

[0011] Preferably, the feeding platform has a through hole for connecting rectangular grooves, the drive shaft is clearance-fitted with the through hole, and an operation knob is fixed at one end of the drive shaft that protrudes from the through hole.

[0012] Preferably, the protective mechanism includes a baffle fixed to the outer wall of the loading platform and a protective plate sliding on the loading platform, wherein the protective plate, after sliding, cooperates with the baffle to form a protective zone.

[0013] Preferably, the feeding platform is provided with a sliding groove, and the protective plate slides in conjunction with the sliding groove, and the protective plate is "L" shaped.

[0014] Preferably, the protective plate and the baffle are each provided with a magnet, and the two magnets have opposite magnetic properties.

[0015] The advantages of this utility model are:

[0016] 1. This utility model, through the structural design of a rectangular groove, a pallet, and an adjustment mechanism, allows the cardboard to be placed on the pallet, which in turn supports the cardboard, greatly reducing the force required by workers to lift the bottom of the cardboard. Workers can perform the loading operation more easily, effectively reducing the overall labor intensity. At the same time, the tilt angle of the pallet can be adjusted according to actual needs. Through personalized adjustment, workers can adjust the operating angle to suit their own needs and meet the usage requirements of different workers.

[0017] 2. Through the structural design of the protective mechanism and the protective plate, the present invention forms a protective zone after the protective mechanism and the protective plate are combined to protect the operating knob of the adjustment mechanism, thereby preventing workers from accidentally bumping into the operating knob during operation, which would cause the pallet angle to change, and improving the continuity of the cutting and feeding work.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The present application will be further described in detail below with reference to the accompanying drawings 1-4.

[0026] This application discloses a slitting apparatus for cardboard processing. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A cardboard slitting device includes a slitting machine 1, an adjusting mechanism 4, and a protective mechanism 5. A feeding platform 2 is fixed on the slitting machine 1. A rectangular groove 200 is provided on the feeding platform 2. A pallet 3 for lifting the cardboard is rotatably connected to the rectangular groove 200.

[0027] Among them, the feeding platform 2 provides support for the temporary storage and conveying of cardboard before slitting. It has a plate structure and is made of high-strength, wear-resistant metal materials, such as Q345B steel.

[0028] The surface of pallet 3 is treated with anti-slip material, for example, by forming a uniform pattern on the surface through a knurling process, which increases the friction between the pallet and the cardboard and prevents the cardboard from sliding during the feeding process.

[0029] Among them, the slitting machine 1, which requires manual feeding, is a technology well-known to those skilled in the art, and the specific cardboard slitting operation will not be described in detail here.

[0030] The adjustment mechanism 4 is installed on the rectangular groove 200 and is used to adjust the tilt angle of the tray 3.

[0031] The protective mechanism 5 is installed on the feeding platform 2 and is used to protect the drive end of the adjustment mechanism 4.

[0032] Reference Figure 1 , Figure 2 and Figure 3 One end of the tray 3 is fixedly connected to a rotating shaft, and both sides of the inner wall of the rectangular groove 200 are provided with round holes, and the two ends of the rotating shaft are respectively clearance-fitted with the round holes.

[0033] Reference Figure 3 The adjusting mechanism 4 includes a threaded rod 400, one end of which is rotatably connected to the side of the inner wall of the rectangular groove 200. A threaded cylinder 401 is threadedly fitted onto the rectangular groove 200. A first support rod 402 is hinged to the top of the threaded cylinder 401. The other end of the first support rod 402 is hinged to the bottom of the support plate 3. A drive shaft 403 is fixedly connected to one end of the rectangular groove 200 and extends out of the rectangular groove 200.

[0034] Reference Figure 3 A guide rod 404 is fixed on the rectangular groove 200. A sliding cylinder 405 is fitted onto the guide rod 404 with clearance. A second support rod 406 is hinged to the sliding cylinder 405. The other end of the second support rod 406 is hinged to the bottom of the support plate 3. During the adjustment of the tilt angle of the support plate 3, the second support rod 406 works in conjunction with the first support rod 402. The sliding cylinder 405 slides on the guide rod 404, providing stable support and guidance for the support plate 3 and preventing the support plate 3 from shifting or shaking during the adjustment process.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The feeding platform 2 has a through hole with a connected rectangular groove 200. The drive shaft 403 is clearance-fitted with the through hole. An operating knob is fixed at one end of the drive shaft 403 that protrudes from the through hole. The surface of the operating knob is designed to be non-slip, such as with a rubber non-slip sleeve or knurling, so that the operator can easily rotate the drive shaft 403 manually.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The protective mechanism 5 includes a baffle 500 fixed to the outer wall of the loading platform 2 and a protective plate 501 sliding on the loading platform 2. After the protective plate 501 slides, it cooperates with the baffle 500 to form a protective zone. The operating knob is located in the protective zone. The protective zone can protect the operating knob, thereby preventing workers from accidentally bumping into the operating knob during work, which would cause the angle of the pallet 3 to change, thus improving the continuity of the cutting and loading work.

[0037] Reference Figure 3 and Figure 4 The loading platform 2 is provided with a sliding groove, and the protective plate 501 slides in conjunction with the sliding groove. The protective plate 501 is L-shaped.

[0038] Reference Figure 3 and Figure 4 The protective plate 501 and the baffle 500 are respectively equipped with magnets. The two magnets have opposite magnetic properties. When the protective plate 501 slides to the position where it docks with the baffle 500, the two magnets attract each other and generate a certain adsorption force, which firmly fixes the protective plate 501 in the protective position, preventing the protective plate 501 from being displaced due to equipment vibration or other external forces, and ensuring the integrity and protective effect of the protected area.

[0039] Working principle: During use, the operator can place the stacked cardboard on the inclined pallet 3. The pallet 3 supports and lifts the cardboard, and the operator only needs to move the surface cardboard to load it. The lifting effect of the pallet 3 reduces the operator's workload in lifting the cardboard. When different operators need to adjust the angle of the pallet 3 according to their operating habits, they slide the protective plate 501 away from the baffle 500 and then turn the operating knob. The operating knob drives the drive shaft 403 to rotate, which in turn causes the threaded rod 400 to rotate. The rotation of the threaded rod 400 causes the threaded cylinder 401 to move. With the cooperation of the guide rod 404 and the sliding cylinder 405, the first support rod 402 and the second support rod 406 together lift the pallet 3, thereby changing the angle of the pallet 3.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
