Description

Technical Field

[0001] The utility model relates to the technical field of edge trimming devices, in particular to an edge trimming device for cardboard. Background Art

[0002] In the paper production process, trimming and shaping is a common process. Trimming and shaping requires trimming the cardboard to remove the excess edge materials on both sides of the cardboard. When trimming the cardboard, a cardboard trimming device is required.

[0003] When the trimming device in the prior art performs trimming processing on the cardboard, it is impossible to effectively and conveniently adjust the distance between the cutting knives. When the trimming processing on the cardboard is performed, the cutting knife is generally required to be used. However, since different users have different requirements on the size of the cardboard after trimming, if the distance between the cutting knives cannot be adjusted, it will result in that the user cannot perform trimming processing on the cardboard of different sizes through one trimming device. When it is necessary to perform trimming processing on the cardboard of different sizes, it is necessary to replace the trimming devices of different specifications, which will increase the user's use cost and reduce the trimming efficiency of the cardboard by the trimming device. In addition, the trimming device in the prior art cannot conveniently disassemble and replace the cutting knife. After the cutting knife is used for a long time, it is inevitable that it will be worn out. At this time, if the cutting knife is not replaced, the cutting efficiency of the cutting knife will be reduced, thereby resulting in low efficiency of the trimming device.

[0004] In contrast to the Chinese patent with publication number CN218195469U, the utility model discloses a cardboard trimming device, comprising a rectangular paper support plate, wherein the paper support plate is rotatably provided with cutting knives in the shape of long strips and parallel to each other on both sides along the width direction, a knife driving mechanism for driving the cutting knife to rotate is provided at the bottom of the paper support plate, and trimming knife grooves for cooperating with the cutting knife to cut the cardboard are provided on both sides of the paper support plate along the width direction. When cutting the cardboard, the knife driving mechanism drives the cutting knife to rotate around the rotating shaft, and the cutting of paper can be achieved by cooperating with the trimming knife groove, and the cardboard can be cut by reciprocating opening and closing like scissors, which is suitable for various types of hard and soft cardboards.

[0005] The above solution can easily trim the cardboard, but it still cannot effectively and conveniently adjust the distance between the cutting knives, and cannot effectively disassemble and replace the cutting knives, and fails to solve the problems raised in the above background technology.

[0006] In view of this, we propose a paperboard trimming device. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 - Figure 6 As shown, this embodiment provides a paperboard trimming device, including a processing table 1, and also includes:

[0029] A connecting plate 2 is fixedly connected to one side of the processing table 1;

[0030] The cutting boards 5 are symmetrically arranged above the processing table 1. A cutting knife 8 is arranged below the two cutting boards 5. The upper surface of the processing table 1 is provided with guide grooves for the cutting knife 8 to move at equal intervals. The upper surfaces of the two cutting boards 5 are fixedly connected with handles 6. The outer surfaces of the two handles 6 are covered with anti-slip sleeves 7.

[0031] An adjustment component is provided on the upper surface of the connecting plate 2 and is used to adjust the distance between the two cutting plates 5, so that the user can adjust the distance between the cutting blades 8 according to actual needs;

[0032] The collecting components are respectively arranged in front of and behind the processing table 1 and are used to collect waste generated during trimming.

[0033] The above working principle: when it is necessary to trim the cardboard, just press the handle 6, at this time the handle 6 drives the cutting board 5 to move synchronously, and the cutting board 5 drives the cutting knife 8 to move synchronously, at this time the cardboard can be conveniently trimmed by the cutting knife 8, when it is necessary to adjust the distance between the cutting knives 8 according to actual needs, it is only necessary to adjust the distance between the cutting knives 8 conveniently through the adjustment component, so that it is convenient for the user to perform trimming of cardboards of different sizes. During the trimming process, a large amount of waste will be generated. At this time, it is only necessary to place the waste in the collecting component, and the waste can be effectively collected by the collecting component. When the cutting knife 8 needs to be replaced, it can also be disassembled very conveniently, saving time and effort.

[0034] In order to effectively adjust the distance between the cutting knives 8 according to actual needs, the adjusting component includes an adjusting plate 3 fixedly connected to the upper surface of the connecting plate 2, a bidirectional threaded rod 10 is provided inside the adjusting plate 3, one end of the bidirectional threaded rod 10 is rotatably connected to the inner wall of the adjusting plate 3, the other end of the bidirectional threaded rod 10 extends to the outside of the adjusting plate 3 and is fixedly connected with a knob 4, and thread blocks 11 are symmetrically provided on the outside of the bidirectional threaded rod 10. A guide groove for the movement of the thread blocks 11 is provided on the upper surface of the adjusting plate 3, and a fixing frame 12 is fixedly connected to the upper surfaces of the two thread blocks 11. When it is necessary to adjust the distance between the cutting knives 8, it is only necessary to rotate the knob 4. At this time, the knob 4 drives the bidirectional threaded rod 10 to rotate synchronously, and the two thread blocks 11 move synchronously on the outside of the bidirectional threaded rod 10, driving the fixing frame 12 to move synchronously, and the fixing frame 12 drives the cutting plate 5 to move synchronously, and the cutting plate 5 drives the cutting knives 8 to move synchronously. At this time, the distance between the cutting knives 8 can be adjusted according to actual needs.

[0035] Considering that after using the cutting knife 8 to trim the cardboard, the cutting knife 8 needs to be reset to facilitate the user to perform the next trimming process, the two fixed frames 12 are provided with fixed rods 15 inside, and the outsides of the two fixed rods 15 are fixedly connected with torsion springs 16, and the other ends of the two torsion springs 16 are fixedly connected with rotating sleeves 17, and the outsides of the two rotating sleeves 17 are fixedly connected to one side of the cutting board 5. The outsides of the two fixed frames 12 are provided with guide grooves for the cutting board 5 to move. When the cutting knife 8 is needed to trim the cardboard, just press the handle 6. At this time, the handle 6 drives the cutting board 5 to move synchronously, and the cutting board 5 drives the cutting knife 8 to move synchronously. During the movement of the cutting board 5, the rotating sleeve 17 is also driven to rotate synchronously. At this time, the torsion spring 16 is stretched. When the trimming process is completed, just release the handle 6. At this time, the torsion spring 16 is reset, driving the rotating sleeve 17 to rotate synchronously. The rotating sleeve 17 drives the cutting board 5 to move synchronously, and the cutting board 5 drives the cutting knife 8 to reset and move synchronously. At this time, the cutting knife 8 can be reset, so that the user can perform the next trimming process on the cardboard.

[0036] In order to facilitate the disassembly and replacement of the cutting knife 8, the bottom of the two cutting plates 5 are fixedly connected with a mounting plate 18, and the interior of the two mounting plates 18 is provided with a clamping groove for clamping a T-shaped plate 19. The two T-shaped plates 19 are fixedly connected to the mounting plate 18 by bolts, and the bottoms of the two T-shaped plates 19 are fixedly connected to the upper surface of the cutting knife 8. When the cutting knife 8 needs to be disassembled and replaced, it is only necessary to unscrew the bolts and then pull the T-shaped plate 19 out of the clamping groove inside the mounting plate 18. At this time, the T-shaped plate 19 drives the cutting knife 8 to move synchronously, so that the cutting knife 8 can be conveniently disassembled, thereby facilitating its replacement.

[0037] In order to effectively collect the waste generated during trimming, the collecting component includes connecting blocks 13 symmetrically arranged on the front end surface and the rear end surface of the processing table 1, and a connecting rod 14 is provided between every two connecting blocks 13. The outside of the two connecting rods 14 is provided with a collecting frame 9. When the cardboard is trimmed, a large amount of waste will be generated. At this time, the waste only needs to be placed in the collecting frame 9 to conveniently collect and process the waste. When the waste in the collecting frame 9 needs to be cleaned, the collecting frame 9 only needs to be pulled out from the outside of the connecting rod 14.

[0038] In addition, in order to prevent the device from being displaced during use and causing danger, a base 21 is provided under the processing table 1, and support rods 20 are symmetrically provided on the upper surface of the base 21. The top ends of the two support rods 20 are fixedly connected to the bottom of the processing table 1, and an anti-skid pad is bonded to the bottom of the base 21. The bottom of the anti-skid pad has herringbone anti-skid grooves at equal intervals. The anti-skid pad and the herringbone anti-skid grooves can effectively prevent the device from being displaced during use and causing danger.
