Technical Field

[0001] The utility model relates to the field of printed matter processing, in particular to a printed matter cutting device. Background Art

[0002] In the modern printing paper processing industry, the printing paper usually needs to be cut smoothly at the edge during the cutting process. During multiple processing processes, the cutting operation will generate a large amount of waste. In order to keep the processing table clean and ensure the processing quality, the waste needs to be cleaned up in time. However, the existing technology mainly uses manual cleaning of the waste on the processing table, that is, the operator manually cleans the waste generated on the upper end surface of the processing table.

[0003] However, this manual cleaning method has many inconveniences. First, since the cutting operation is repeated, the operator needs to repeatedly clean the waste chips, which not only reduces the work efficiency, but also increases the labor intensity of the operator. Secondly, during the manual cleaning of waste chips, the operator needs to touch the waste chips on the processing table, which poses certain safety hazards. In addition, manual cleaning of waste chips is not conducive to keeping the working environment clean.

[0004] Therefore, it is necessary to design a device that can automatically clean the debris generated by printing paper cutting. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the technical problem of the utility model is to provide a device that can automatically clean the printed debris on the end surface of the processing table.

[0006] The technical implementation scheme of the utility model is as follows: a printed matter cutting device comprises a processing platform, the upper end surface of the processing platform is provided with a vertically penetrating receiving groove, one side of the receiving groove is provided with a cutting mechanism, a lifting plate is embedded in the receiving groove, and horizontally extending cross bars are respectively provided at both ends of the lifting plate, and first vertical slide grooves that slide with the cross bars are provided on both sides of the processing platform, and the first vertical slide grooves limit the highest position of the lifting plate. When it is in the highest position, the lifting plate is flush with the upper end surface, and the end of the cross bar is slidably arranged on a sliding column, and the two ends of the sliding column are respectively provided with first vertical slide grooves that slide with the cross bars. The cam is fixed to the side of the processing platform through an ear plate, and the slide column is consistent with the setting direction of the first vertical slide groove. A spring is sleeved on the slide column, and the two ends of the spring are respectively abutted on the cross bar and the ear plate away from the upper end surface of the processing platform. A second spur rack is provided on one side of the cross bar, and a gear that can be meshed with the second spur rack is rotatably provided on the side of the processing platform. A first spur rack is provided on the cutter side of the cutting mechanism, and the first spur rack is located on the side opposite to the second spur rack and can mesh with the gear. A fan is also included, and the fan is provided on one side of the bottom of the accommodating groove.

[0007] In addition, it is particularly preferred that the first spur rack is in non-continuous contact with the gear, and when the first spur rack is at the highest point, the gear is disengaged from the first spur rack and contacts the lowest teeth of the second spur rack.

[0008] In addition, it is particularly preferred that the cutting mechanism includes a tool holder, a cylinder and a cutter, the tool holder is arranged in an inverted U shape on the end surface of the processing platform, the cylinder is arranged on the top of the tool holder, and the cylinder movable rod penetrates the tool holder downward and is fixedly connected to the cutter.

DETAILED DESCRIPTION

[0024] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0025] like Figure 1 and Figure 5The structural diagrams of the two states of the device are respectively shown. The cutting device includes a processing platform 1. A vertically penetrating receiving groove is opened in the middle of the upper end surface of the processing platform 1 along its length direction. A cutting mechanism is provided on one side of the receiving groove. A lifting plate 10 is embedded in the receiving groove. Specifically, the cutting mechanism includes a support tool holder 2, a cutter 4 for cutting printed paper, and a cylinder 3 for driving the cutter 4 to operate. The cylinder 3 is arranged on the top of the tool holder 2, and its movable rod penetrates the tool holder 2 from top to bottom, driving the cutter 4 to cut in the vertical direction. It should be noted that the tool holder 2 is in an inverted U shape, and the lower end is fixed. On the upper end surface of the processing platform 1, horizontally extending cross bars 7 are respectively provided at both ends of the lifting plate 10, and first vertical slide grooves slidably matched with the cross bars 7 are provided on both sides of the processing platform 1. A sliding column 8 is arranged along one side of the first vertical slide groove of the processing platform 1. Specifically, both ends of the sliding column 8 are fixed to the side of the processing platform 1 through ear plates, and the setting direction of the sliding column 8 is consistent with the setting direction of the first vertical slide groove. The cross bar 7 passes through the first vertical slide groove and is slidably connected with the sliding column 8. A spring 9 is sleeved on the sliding column 8, and the upper end of the spring 9 abuts against the bottom of the cross bar 7, and the lower end of the spring 9 abuts against the upper side of the ear plate away from the upper end surface of the processing platform 1.

[0026] It is particularly important to note that the spring 9 applies an upward force to the cross bar 7, so that the cross bar 7 abuts against the top wall of the first vertical slide groove. This position limits the highest position of the lifting plate 10, so that it is flush with the upper end surface of the processing platform 1. In order to prevent the bottom paper from getting stuck in the receiving groove during feeding and cutting, a number of balls 12 are evenly arranged on the upper end surface of the processing platform 1 and the upper end surface of the lifting plate 10. In addition, a second spur rack 71 is fixedly provided on one side of the end of the cross bar 7, and a first spur rack 5 is provided on the side of the cutting mechanism. The second spur rack 71 and the first spur rack 5 are arranged opposite to each other, and a gear 6 is provided therebetween. The gear 6 is rotatably connected to the side of the processing platform 1 through a rotating shaft. Specifically, the first spur rack 5 includes an integrally formed vertical part and a horizontal part, wherein one end of the horizontal part is fixedly connected to the side of the cutter 4, and teeth are provided at the lower end of the vertical part.

[0027] refer to Figure 1-2When the cylinder 3 drives the cutter 4 to cut downward, the cutter 4 synchronously drives the first spur rack 5 to move downward. In a preferred embodiment, the first spur rack 5 is in non-continuous contact with the gear 6, that is, after the first spur rack 5 runs downward for a period of idle travel, it contacts and meshes with the gear 6 and drives the gear 6 to rotate. Moreover, when the gear 6 rotates, it contacts the teeth at the lower end of the second spur rack 71, and the two form a slipping state. During this process, while completing the cutting process, the lifting plate 10 is always flush with the upper end surface of the processing platform 1. After the cutting is completed, the debris falls on the lifting plate 10. At this time, the cylinder 3 drives the cutter 4 to rise. Similarly, the first spur rack 5 drives the gear 6 to rotate in the opposite direction. At this time, the gear 6 rotates to mesh with the second spur rack 71 and drives the second spur rack 71. The second spur rack 71 moves in the opposite direction to the first spur rack 5, and then drives the lifting plate 10 to move downward through the cross bar 7. The cross bar 7 slides downward along the sliding column 8 to compress the spring 9. When the lifting plate 10 drives the debris to descend to the bottom of the upper end surface of the processing platform 1, the fan 11 arranged at the bottom of the upper end surface of the processing platform 1 and on one side of the accommodating groove is started to blow the debris away from the lifting plate 10. As the first spur rack 5 continues to rise, the first spur rack 5 is out of contact with the gear 6. At this time, the spring is reset, driving the cross bar 7 and the lifting plate 10 to reset, thus completing a cycle of automatic debris cleaning. Repeating the above steps can automatically clean the debris in the repeated trimming process, which can not only improve the processing efficiency but also reduce the labor intensity of the staff.

[0028] like Figure 4 As shown, the feeding assembly includes a rear baffle 15 and an electric push rod 16. The rear baffle 15 is arranged along the length direction of the upper end surface of the processing platform 1. The electric push rod 16 is arranged horizontally. The movable rod of the electric push rod 16 faces the front end of the processing platform 1. The movable rod of the electric push rod 16 is fixedly connected to the rear baffle 15. The frame is fixedly arranged on one side of the tool holder 2. The electric push rod 16 drives the rear baffle 15 to move back and forth along the upper end surface of the processing platform 1. The printed paper can be continuously pushed to move in the cutting direction of the cutter 4.

[0029] like Figure 3 As shown, the blanking assembly also includes an inclined plane 14 arranged at the bottom of the upper end surface of the processing platform 1, the inclined plane 14 is inclined from front to rear, and a stretchable front side plate 13 is arranged at the lower end thereof. Specifically, the front side plate 13 is pulled and matched with the processing platform 1. The fallen debris falls freely along the inclined plane 14 and falls to the bottom of the inclined plane 14. By pulling open the front side plate 13, the waste debris can be recovered.

[0030] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
