Description

Technical Field

[0001] The utility model relates to the technical field of paper cutting, in particular to a cutting device for paper production. Background Art

[0002] In the continuous production of paper, in order to facilitate storage and subsequent processing, the finished paper is generally wound into a cylinder. With this setting, according to the needs of customers, the rolled paper can be cut into multiple papers of different sizes by using a cutting device.

[0003] Although the cutting device can divide the rolled paper into multiple independent papers, the sizes of the papers made in this way are still relatively large, and the edges of multiple stacked papers are uneven. Therefore, it is still necessary to use a cutting device to trim and slit them.

[0004] At present, the structures of the devices used for paper trimming and slitting are relatively complex and the costs are relatively high. For example, a cutting machine disclosed in a Chinese patent with the patent publication number CN211729273U includes a cross-cutting device, a support plate, a pushing device, an adjustment platform, a first driving device and a first moving structure. The adjustment platform is connected to the first driving device through the first moving structure and the adjustment platform moves on the support plate under the drive of the first driving device, etc. When using the cutting machine provided by the above patent and similar cutting machines to cut paper, it is necessary for the staff to manually adjust multiple papers stacked up and down. When manually adjusting the orientation of the stacked papers, it is very easy to cause the papers distributed up and down to be misaligned, and it is also necessary for the staff to trim the positions of the upper and lower papers. Only through such operations can it be ensured that multiple papers have the same size. However, this increases the steps of paper cutting and the efficiency is low. At the same time, the quality of the stacked papers is relatively large, and if the staff repeats the above steps for a long time, it will cause fatigue. Summary of the Utility Model

[0027] The following will be further described in conjunction with the accompanying drawings and specific embodiments:

[0028] Embodiment 1

[0029] As Figure 1 shown, a cutting device for paper production includes a bracket 1, a cutting knife 2, a supporting plate 3, a support board 4, a collection bin 5 and a baffle 6. The bracket 1 is arranged in a U-shaped structure with the opening facing downwards. Two support plates 12 are vertically arranged at the lower end of the bracket 1. Legs 14 are arranged below the support plates 12, and the legs 14 and the support plates 12 also form a U-shaped structure with the opening facing forward. The cutting knife 2 is arranged inside the bracket 1, and a telescopic cylinder (which can be an electric cylinder or a hydraulic cylinder) is arranged above it. The telescopic cylinder penetrates through the top of the bracket 1. The support board 4 is adjustably arranged between the two support plates 12, and a stepped hole 41 is arranged on the support board 4. The baffle 6 is adjustably arranged above the two support plates 12 and is located behind the bracket 1. The collection bin 5 is arranged between the legs 14 and is located below the support board 4. The upper end of the collection bin 5 is open and protrudes from the legs 14. The supporting plate 3 is arranged at the stepped hole 41, and a control board 37 is arranged below it. The control board 37 is hinged to the supporting plate 3 and the support board 4. When using this device to trim or cut stacked paper, place the stacked paper on the support board 4 and set it opposite to the supporting plate 3. According to the cutting requirements, adjust the position of the baffle 6 and fix it. Push the support board 4 to drive the stacked paper to move, so that the rear end of the stacked paper contacts the baffle 6. At the same time, start the telescopic cylinder to control the cutting knife 2 to descend, and trim the edge of the stacked paper or cut the stacked paper. After the initial treatment of the stacked paper, the staff pulls the support board 4 forward until the stacked paper separates from the baffle 6. After leaving a suitable gap between the stacked paper and the baffle 6, the staff operates the control board 37 to control the supporting plate 3 to rise, and at the same time lift the stacked paper. After the stacked paper separates from the support board 4, the staff can rotate the stacked paper and the supporting plate 3 as a whole to realize the overall adjustment of the direction of the stacked paper, changing the current situation of manual adjustment of the paper direction with misalignment between the upper and lower papers, reducing the paper cutting steps, and correspondingly improving the paper cutting efficiency. After adjusting the orientation of the paper, push the support board 4 to drive the stacked paper to move backward again, so that the stacked paper contacts the baffle 6, and the paper is trimmed or cut for the second time under the action of the cutting knife 2. Repeating the above steps can complete the processing of the paper. The waste paper generated by cutting the paper falls into the collection bin 5, which is convenient for the staff to clean up. And this device has a simple structure and a low assembly cost. Compared with the existing cutting machine, it can greatly reduce the cost of paper production. It should be emphasized that the sizes of the supporting plate 3 and the stepped hole 41 can be determined according to actual needs. In short, it provides convenience for lifting the stacked paper. In order to control the operation of this device, a control box can also be set. The control box is a prior art and will not be elaborated in detail here.

[0030] As Figure 2 、 Figure 5As shown, in order to realize the adjustable setting of the support plate 4 and the support plate 12, a buckle groove 13 is provided on the side of the two support plates 12 close to each other, and the buckle groove 13 is provided along the length direction of the support plate 12, and the end is set to be open, and the central angle of the buckle groove 13 can be set to a state greater than 180°. A buckle column 43 is provided on the side of the support plate 4, and the buckle column 43 is located in the buckle groove 13. Under the cooperation of the buckle groove 13 and the buckle column 43, the support plate 4 is stably and movably arranged between the two support plates 12, providing support for the staff to pull the support plate 4 to drive the stacked paper to move forward and backward. If the central angle of the buckle groove 13 is greater than 180°, the relative position of the two support plates 12 can be prevented from moving away from each other under the action of external force, thereby enhancing their relative stability.

[0031] like Figure 6 As shown, in order to adjust the orientation of multiple sheets of paper synchronously, the upper end of the supporting plate 3 can be connected with a rotating plate through a thrust spherical roller bearing, and a sleeve 32 is fixedly provided in the middle of the lower side surface. At the same time, a first connecting frame 34 and a second connecting frame 35 are provided below the supporting plate 3. The lower ends of the first connecting frame 34 and the second connecting frame 35 are both hinged to the control board 37. Specifically, the second connecting frame 35 is hinged to the end of the control board 37, and the second connecting frame 35 is hinged to the strip hole 38 on the middle side of the control board 37. The upper end of the first connecting frame 34 can be inserted into the sleeve 32 through a bearing connection, and the relative position of the sleeve 32 and the first connecting frame 34 can also be limited by a limit bolt. The upper end of the second connecting frame 35 is threadedly inserted into the supporting plate 4. In this arrangement, the staff can hold the free end of the control board 37 and lift it, and use the lever principle to force the supporting plate 3 to rise. The rising supporting plate 3 contacts the stacked paper, thereby lifting the stacked paper and forcing the stacked paper to leave the supporting plate 4. After the stacked paper leaves the support plate 4, the staff can adjust the orientation of the multiple papers simultaneously. If a rotating disk is provided on the support plate 3, the rotation of the rotating disk can provide support for the adjustment of the orientation of the stacked paper. The first connecting frame 34 is connected to the sleeve 32, which also provides convenience for the rotation and adjustment of the orientation of the stacked paper.

[0032] like Figure 6 As shown, when the sleeve 32 is connected to the first connecting frame 34 by a limiting bolt, the side wall thread of the sleeve 32 is penetrated by a limiting bolt, and the upper end of the first connecting frame 34 is provided with an annular groove 36, and the end of the limiting bolt extends into the annular groove 36. This arrangement can quickly disassemble and assemble the sleeve 32 and the first connecting frame 34, provides convenience for maintenance or replacement, and improves the flexibility of the device.

[0033] like Figure 1 , Figure 5As shown, in order to prevent the presence of the supporting tray 3 from affecting the stacked paper being laid flat on the supporting plate 4, the upper side surface of the supporting tray 3 is parallel to the upper side surface of the supporting plate 4, and a stepped annular groove 33 is provided at the lower end of the supporting tray 3, and a ball 42 is embedded in the stepped hole 41, and the ball 42 contacts the top surface of the stepped annular groove 33.

[0034] like Figure 2 , Figure 4 As shown, in order to be able to quantitatively adjust the position of the baffle 6, a scale groove 15 is provided on the support plate 12, and a buckle plate 61 is provided at the end below the baffle 6. A pressure bolt is threaded through the buckle plate 61 and is buckled on the support plate 12. The pressure bolt presses the side wall of the support plate 12. By referring to the scale groove 15, the quantitative adjustment of the baffle 6 is achieved. After adjustment, the pressure bolt is rotated to make its end press against the support plate 12, so that the baffle 6 is controlled to be stably placed relative to the support plate 12.

[0035] like Figure 2 , Figure 3 As shown, in order to limit the lifting and lowering of the cutting knife 2, a notch 21 is provided at the end of the cutting knife 2, and a clamping plate 22 is provided at the notch 21, and the clamping plate 22 protrudes from the cutting knife 2. At the same time, a clamping slot 11 is provided on the bracket 1, and the clamping plate 22 extends into the clamping slot 11. Under the cooperation of the clamping slot 11 and the clamping plate 22, the cutting knife 2 is limited to be lifted and lowered along the height direction of the bracket 1.

[0036] Example 2

[0037] like Figure 7 , Figure 8 As shown, on the basis of Example 1, in order to further reduce the labor intensity of the staff, a threaded hole 31 is provided at the free end of the control plate 37, and an adjusting screw 7 is threadedly provided at the threaded hole 31, and a connecting ball 71 is fixedly provided at the upper end of the adjusting screw 7. A mounting groove 44 is provided on the lower side of the support plate 4, and a splicing plate 45 is provided at the mounting groove 44 connected by bolts. The splicing plate 45 and the mounting groove 44 form a curved groove with a central angle greater than 180°, and the connecting ball 71 is located at the curved groove. When it is necessary to lift the supporting plate 3, the staff rotates the adjusting screw 7 to drive the free end of the control plate 37 to rise and fall, thereby forcing the supporting plate 3 to rise and fall. The setting of the splicing plate 45 facilitates quick disassembly and assembly according to needs, and provides convenience for disassembling the adjusting screw 7.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
