Description

Technical Field

[0001] This utility model relates to the field of roll paper slitting technology, and in particular to a roll paper slitting device. Background Technology

[0002] The slitting machine is a key piece of equipment on the roll paper production line. It typically feeds a wider roll of paper into the machine, and the rollers are driven to rotate by a power mechanism. The rollers are equipped with circular knives. Before slitting, the multiple circular knives on the rollers need to be adjusted to a suitable equidistant position. The roll paper is brought close to the circular knives to achieve equidistant slitting of the roll paper.

[0003] Currently, to facilitate the adjustment of the circular blade position, some methods involve manually arranging each blade by comparing it with the scale lines. However, due to human factors, there are often errors in the position of the blades, resulting in uneven paper cutting. Other methods use an automatic circular blade arrangement system to arrange the blades. The system sets the spacing between two blades, and a moving marker is placed below each blade. When the marker moves to the set position, it stops, and then the blade is fixed at the position where the marker stops, thus adjusting the spacing between the two blades. Although this solves the problem of human error, the circular blade arrangement system requires the previous blade spacing to be arranged before the next blade spacing can be adjusted, adjusting one group at a time. The efficiency still needs improvement, and it requires a complex transmission system, which will increase the economic cost for small factories.

[0004] Therefore, based on the above situation, it is necessary to design a roll paper slitting device to solve the above problems. Utility Model Content

[0005] This invention provides a roll paper slitting device to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A roll paper slitting device includes a slitting mechanism. The slitting mechanism has a first roller and a second roller arranged vertically and parallel to each other, forming a slitting gap between the first roller and the second roller. A plurality of circular blades are movably mounted on the first roller, and a plurality of bottom blades corresponding to the circular blades are movably mounted on the second roller. A scissor linkage assembly is provided below the bottom blades. The scissor linkage assembly has a plurality of markers corresponding to the bottom blades. The markers are used to position the bottom blades. When the scissor linkage assembly extends or retracts, it drives the plurality of markers to move synchronously, thereby realizing the synchronous adjustment of the distance between two adjacent markers.

[0008] Preferably, the scissor lift linkage assembly includes multiple sets of scissor lift units that are hinged to each other. Each scissor lift unit includes two cross-arranged connecting rods that are rotatably connected by a connecting shaft. The marker rod is mounted on the connecting shaft.

[0009] Preferably, the measuring rod includes a fixed seat connected to the connecting shaft and a measuring rod rotatably connected to the fixed seat via a damping rotating shaft.

[0010] Preferably, the slitting mechanism is movably provided with a receiving seat, the scissor linkage assembly is disposed within the receiving seat, and the bottom of the receiving seat is provided with a telescopic support member.

[0011] Preferably, the receiving seat is provided with scale lines, and a pointer is rotatably connected to the measuring rod.

[0012] Preferably, one end of the scissor lift linkage assembly is rotatably connected to a pull rod for stretching the scissor lift linkage assembly.

[0013] The beneficial effects of this utility model are as follows: by adjusting the telescopic movement of the scissor lift linkage assembly, multiple marker members mounted on it can be moved synchronously. At this time, the distance between two adjacent marker members can be adjusted equally. Through the positioning marking function of the marker members, the round blade and bottom blade corresponding to each marker member can be adjusted to the position of the marker member, avoiding the need to position the marker members one by one and improving the adjustment efficiency.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-5 As shown, a roll paper slitting device includes a slitting mechanism 1 with multiple traction rollers rotating on it. During use, the paper to be slitted passes through these rollers, maintaining a uniform speed. As the paper moves, it gradually approaches a first roller 2 and a second roller 3, which are vertically and horizontally balanced on the slitting mechanism 1. A slitting gap is formed between the first roller 2 and the second roller 3, guiding the paper into the gap. At this time, a circular blade 4 movably mounted on the first roller 2 and a bottom blade 5 movably mounted on the second roller 3, corresponding to the circular blade 4, cooperate to slit the paper passing through the gap. To ensure uniform paper slitting during this process, the spacing between adjacent circular blades 4 and adjacent bottom blades 5 needs to be adjusted to equal distances. In the divided state, to improve the efficiency of equal division, a scissor linkage assembly is provided below the bottom blade 5. The scissor linkage assembly has multiple markers 7 that correspond one-to-one with the bottom blade 5 for positioning the bottom blade 5. By adjusting the extension and retraction movement of the scissor linkage assembly, the multiple markers 7 move synchronously. Due to the structural characteristics of the scissor linkage assembly, the distance between two adjacent markers 7 can be adjusted synchronously. Then, according to the position of each marker 7, the corresponding bottom blade 5 and round blade 4 are moved to contact the marker 7 and are fixed at the contact position. At this time, the distance between two adjacent bottom blades 5 and two adjacent round blades 4 is equal, avoiding the need for the markers 7 to be positioned group by group, thus improving the adjustment efficiency.

[0023] Reference Figure 5As shown, furthermore, in order to synchronously adjust the spacing between two adjacent marker members 7, the scissor lift linkage assembly includes multiple sets of mutually hinged scissor lift units. Each scissor lift unit includes two cross-arranged connecting rods 6, which are rotatably connected by connecting shafts 8. The marker members 7 are mounted on the connecting shafts 8. The scissor lift units form a parallelogram mechanism through the cross-hinged connecting rods 6. When the scissor lift assembly extends or retracts as a whole, all connecting shafts 8 (the installation positions of the marker members 7) will move along a parallel trajectory, ensuring that the spacing between adjacent marker members 7 increases or decreases synchronously, completing the adjustment of the spacing of all marker members 7 at once, and improving the adjustment efficiency.

[0024] Reference Figure 4 As shown, further, in order to position the circular blade 4 and the bottom blade 5, the marker 7 includes a fixed seat 71 connected to the connecting shaft 8 and a measuring rod 72 rotatably connected to the fixed seat 71 via a damping shaft 9. When the scissor lift linkage assembly drives multiple sets of marker 7 to move, the movable end of the measuring rod 72 can be tilted at a certain angle away from the bottom blade 5. The damping shaft 9 fixes its tilt angle to avoid affecting the movement of the measuring rod 72 when adjusting the spacing. After the position of the measuring rod 72 is fixed, the movable end of the measuring rod 72 is brought close to the second roller 3, so that it can contact the bottom blade 5 and improve the accuracy of the position of the bottom blade 5.

[0025] Reference Figures 1-3 As shown, furthermore, in order to support the scissor linkage assembly, a receiving seat 10 is movably provided on the slitting mechanism 1. The scissor linkage assembly is located inside the receiving seat 10. A telescopic support member 11 is provided at the bottom of the receiving seat 10. The telescopic support member 11 can be an electric telescopic rod. The connecting shaft 8 at one end of the scissor linkage assembly is fixed inside the receiving seat 10, while the other end is in a movable state, which facilitates the telescopic movement of the scissor linkage assembly. Since the distance between the second roller 3 and the first roller 2 sometimes needs to be adjusted according to different paper thicknesses, and maintenance is sometimes required, the height of the receiving seat 10 and the scissor linkage assembly can be adjusted by the telescopic support member 11, thereby improving the efficiency of machine maintenance.

[0026] In order to facilitate accurate adjustment of the distance between two adjacent measuring rods 7, the receiving seat 10 is provided with a scale line 12, and a pointer 13 is rotatably connected to the measuring rod 72. The scale line 12 can accurately mark the position of the measuring rod 7 when the scissor linkage component moves, which is more intuitive and reduces the use of unnecessary parts. In addition, the rotating pointer 13 is located at the lower end of the measuring rod 72, which can reduce the influence on the position of the pointer 13 when the measuring rod 72 is rotated.

[0027] Reference Figures 2-5As shown, furthermore, in order to facilitate the extension and retraction of the scissor lift linkage assembly, one end of the scissor lift linkage assembly is rotatably connected to a lever 14 for extending the scissor lift linkage assembly. The operator can directly drive the scissor lift linkage assembly to extend and retract through pushing and pulling actions, and adjust the pushing and pulling amplitude and speed at any time, making the operation simple.

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.
