Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to kraft paper cutting equipment. Background Art

[0002] Kraft paper is a tough, water-resistant packaging paper that is brown in color and has a wide range of uses. It is often used to make paper bags, envelopes, exercise books, record covers, files, sandpaper, etc. Therefore, when using kraft paper, the rolled material needs to be cut into appropriate sizes.

[0003] Currently, when cutting rolled kraft paper, one end of the kraft paper needs to be pulled onto the table, and then cut using tools such as a carving knife and a ruler. Since the kraft paper is in a rolled-up state before being unfolded, when the kraft paper is cut, the cut part will roll back due to its toughness, affecting the smooth cutting of the kraft paper, resulting in a skewed cut and poor practicality.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] See also Figure 1-Figure 3 As shown, the utility model provides a kraft paper cutting device, including a table top 1, side baffles 2 are fixedly connected to both sides of the upper surface of the table top 1, and the two side baffles 2 are parallelly distributed along the long side direction thereof, a slide rod 5 is fixedly connected to one side between the two side baffles 2, a sliding sleeve 6 is slidably connected to the slide rod 5, a knife sleeve 7 is rotatably connected to one side of the sliding sleeve 6, a paper cutter 8 matching the internal size of the knife sleeve 7 is inserted in the knife sleeve 7, and an extrusion fixing part 4 for fixing the height position of the paper cutter 8 is provided on the side wall of the knife sleeve 7, a plug-in assembly 3 for fixing the rotation angle of the knife sleeve 7 is provided on the sliding sleeve 6, pressure strips 10 are provided on both sides of the slide rod 5, two of the pressure strips 10 are detachably connected to the side baffles 2, and the two pressure strips 10 are located between the two side baffles 2 and perpendicular to them.

[0024] Reference Figure 3 As shown, the extrusion fixing member 4 includes a nut 4a fixedly connected to the side wall of the knife sleeve 7 and communicated with the interior thereof, a bolt 4b is threadedly connected to the nut 4a, and the end of the bolt 4b abuts against the surface of the paper cutter 8. When the paper cutter 8 is moved to a suitable position in the knife sleeve 7, the bolt 4b is rotated in the nut 4a until the end of the bolt 4b abuts against the surface of the paper cutter 8, thereby completing the extrusion fixing.

[0025] As an optional embodiment, the plug-in assembly 3 includes a pin sleeve 3a fixedly connected to one side of the knife sleeve 7, a pin 3b is inserted in the pin sleeve 3a, a fan-shaped plate 3c is fixedly connected to the sliding sleeve 6, and a plurality of positioning holes 3d for plugging with the pin 3b are penetrated through the fan-shaped plate 3c, and the plurality of positioning holes 3d are evenly distributed in an arc shape. A magnetic plate 3e is fixedly connected to the end of the pin 3b, and the magnetic plate 3e is magnetically connected to the iron pin sleeve 3a. When the knife sleeve 7 is rotated to a suitable angle, a suitable angle is formed between the paper cutter 8 and the kraft paper, which is conducive to cutting the break. Then the pin 3b is simultaneously inserted into the pin sleeve 3a and the positioning hole 3d to complete the angle fixation of the knife sleeve 7. At the same time, the magnetic force of the magnetic plate 3e can prevent the pin 3b from falling off.

[0026] As an optional embodiment, both pressure strips 10 are provided with counterweights, and both ends of the pressure strips 10 are fixedly connected to the limiting blocks 12. The inner walls of the two side baffles 2 are provided with limiting slots 11 that are slidably connected to the limiting blocks 12. The limiting blocks 12 can be inserted into the limiting slots 11. At this time, the pressure strips 10 can be stably placed on the surface of the table top 1 by their own gravity to prevent displacement and dislocation. It is worth mentioning that an anti-slip pad can be provided on the bottom surface of the pressure strip 10 to avoid displacement and dislocation of kraft paper during cutting.

[0027] Furthermore, the cross-sections of the slide rod 5 and the slide sleeve 6 are both designed as regular hexagons, and the upper surface of the slide sleeve 6 is fixedly connected with a push rod 9 that matches the length of the slide rod 5. The push rod 9 can drive the slide sleeve 6 to move freely on the slide rod 5. At the same time, the hexagonal slide rod 5 and the slide sleeve 6 can be limited by their edges to avoid deflection of the paper cutter 8.

[0028] Specifically, a groove 14 adapted to the paper cutter 8 is provided on one side of the surface of the table top 1, and scales 13 are provided on both sides of the upper surface of the table top 1. The groove 14 allows the tip of the paper cutter 8 to penetrate and slide therein, so that the blade directly acts on the kraft paper, thereby avoiding the tip of the knife from being worn on the surface of the table top 1 and causing the knife section to be quickly scrapped, thereby increasing the service life of the paper cutter 8. At the same time, the scale 13 can be used as a reference for the pulling length of the kraft paper, making the cutting more precise.

[0029] With the above structure, when in use, the kraft paper is stretched and laid flat on the surface of the table board 1, then the knife sleeve 7 is rotated and its rotation angle is fixed by the plug-in component 3, and then the paper cutter 8 is inserted into the knife sleeve 7 and fixed by squeezing the fixing part 4, so that the blade of the paper cutter 8 abuts against the surface of the kraft paper, and then the two pressure strips 10 are respectively installed on both sides of the slide rod 5, and by pushing the slide sleeve 6 to move, the paper cutter 8 can be driven to pass through the surface of the kraft paper. During the cutting process, the two sides of the cut of the kraft paper are respectively pressed by the two pressure strips 10 to avoid curling, and the cutting is completed.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
