An automatic slitting mechanism for office paper processing

Abstract

This utility model discloses an automatic slitting mechanism for office paper processing, comprising a slitting machine, a longitudinal slitting component, a transverse slitting component, and a drive motor. The longitudinal slitting component drives the conveyor wheel and the longitudinal slitting blade to rotate via a rotating shaft driven by the motor, realizing the longitudinal cutting of the raw paper into strips while conveying it. The transverse slitting component is driven by the same motor through a belt drive to reciprocate the transverse cutting blade to complete the transverse cutting. The linkage component uses an output gear with missing teeth to control intermittent motion. When the missing teeth of the output gear pass the input gear, the longitudinal cutting pauses and triggers the transverse cutting. After the teeth of the output gear re-mesh the input gear, the longitudinal cutting resumes, realizing a fixed-length slitting cycle. This mechanism integrates longitudinal cutting, transverse cutting, and intermittent conveying into one unit. It realizes the cutting of A3 or A4 office paper sizes through mechanical linkage, and has the characteristics of compact structure and good synchronization, effectively improving slitting efficiency and accuracy.

Description

Technical Field

[0001] This utility model relates to the technical field of paper slitting mechanisms, specifically an automatic slitting mechanism for office paper processing. Background Technology

[0002] With the increasing demand for office paper, the efficiency and reliability of paper slitting equipment have become key factors in the production process. Traditional office paper slitting mechanisms usually use independent longitudinal and transverse slitting devices, which are controlled by different drive systems. This results in complex equipment structures, high maintenance costs, and a high failure rate. In addition, existing slitting mechanisms are insufficient in terms of the synchronization of longitudinal and transverse slitting, which can easily lead to problems such as inaccurate paper feeding and asynchronous cutting blade movements, affecting slitting quality and production efficiency. Summary of the Invention

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide an automatic slitting mechanism for office paper processing with a simple structure and low failure rate.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objective is: an automatic slitting mechanism for office paper processing, including a slitting machine, a longitudinal slitting component, a transverse slitting component, and a drive motor. The longitudinal slitting component is provided on the slitting machine, and the longitudinal slitting component includes a rotating shaft, a longitudinal slitting disc, and conveying wheels. The rotating shaft is rotatably connected to the slitting machine, and multiple sets of conveying wheels are fixedly connected to the rotating shaft. A set of longitudinal slitting discs is fixedly connected to the rotating shaft between every two sets of conveying wheels.

[0005] The slitting machine platform is provided with a transverse cutting component after the longitudinal cutting component. The transverse cutting component includes a guide frame, a lifting platform, a rotating disk, and a transverse cutting blade. The guide frame is fixedly connected to the slitting machine platform, and the lifting platform is slidably connected to the guide frame. The transverse cutting blade is fixedly connected to the bottom of the lifting platform and cooperates with the end face of the slitting machine platform. The rotating disk is rotatably connected to the guide frame, and an eccentric shaft is fixedly connected to the rotating disk. A traction arm is rotatably connected to the eccentric shaft, and the end of the traction arm is rotatably connected to the lifting platform.

[0006] The drive motor is fixedly connected to the slitting machine platform, and the drive motor is connected to the rotating disk and the rotating shaft through a linkage component.

[0007] In the above technical solution, the linkage component includes an output gear, an input gear, and a transmission assembly. An output shaft is rotatably connected to the slitting machine base, and the output gear is fixedly connected to the output shaft. The output gear is poweredly connected to the drive motor, and the output gear has a missing tooth portion.

[0008] The input gear is fixedly connected to the rotating shaft, and the input gear meshes with the output gear.

[0009] The output shaft and the rotating disk are poweredly connected via the transmission assembly.

[0010] In the above technical solution, an input shaft is fixedly connected to the rotating disk, and the input shaft is rotatably connected to the guide frame;

[0011] The transmission assembly includes a driving pulley, a driven pulley, and a transmission belt. The driven pulley is fixedly connected to the input shaft, and the driving pulley is fixedly connected to the output shaft. The driving pulley and the driven pulley are connected by the transmission belt.

[0012] In the above technical solution, the guide frame includes a fixed frame and a guide column fixedly connected to the fixed frame. The fixed frame is fixedly connected to the slitting machine platform, the lifting platform is slidably connected to the guide column, and the rotating disk is rotatably connected to the fixed frame.

[0013] In the above technical solution, a traction shaft is fixedly connected to the lifting platform, and the end of the traction arm is rotatably connected to the traction shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The raw paper can be fed into the slitting machine table, and the drive motor can drive the rotating shaft to rotate through the linkage component, so that the conveying wheel can drive the raw paper to be conveyed. During the conveying process of the raw paper, the rotating longitudinal cutting disc can evenly divide the raw paper into multiple groups of horizontal strips, and the horizontal strips of raw paper continue to be conveyed. When the horizontal strips of raw paper have been conveyed out of a predetermined distance, the linkage component can stop the conveying of the horizontal strips of raw paper, and the drive motor can drive the rotating disc to rotate through the linkage component, so that the lifting table can drive the cross-cutting blade to descend, thereby cutting the horizontal strips of raw paper into the required A3 or A4 office paper.

[0015] Furthermore, in this invention, the linkage assembly consists of an input gear, an output gear with missing teeth, and a transmission assembly. When the drive motor rotates the output gear, the output gear drives the input gear to rotate. At this time, the longitudinal cutting component can convey and longitudinally cut the raw paper. Simultaneously, the rotating disc of the transmission assembly rotates, causing the lifting platform to lower the cross-cutting blade. When the output gear rotates, causing the missing teeth to engage with the input gear, the rotating shaft does not rotate due to the lack of teeth. This prevents the longitudinal component from conveying the raw paper, while the already conveyed paper... The strip-shaped base paper has reached the required length. At this time, the cross-cutting blade has not yet cut the strip-shaped base paper. When the drive motor continues to drive the rotating disk to lower the cross-cutting blade, the strip-shaped base paper does not move. The cross-cutting blade cuts the conveyed strip-shaped base paper. After the cross-cutting is completed, the drive motor continues to drive the rotating disk to rotate. At this time, the cross-cutting blade rises, but the missing tooth part has not yet disengaged from the input gear. When there is a conveying gap between the rising cross-cutting blade and the slitting machine, the teeth of the input gear continue to drive the input gear to rotate. In this way, the longitudinal cutting component continues to convey and longitudinally cut the base paper.

[0016] Through the above continuous cycle, the raw paper can be longitudinally and transversely cut to form the required office paper. This structure is simple, easy to maintain, and can achieve the required operation with just one set of motors. It has good synchronization, reduces electrical components, and lowers the failure rate. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 An automatic slitting mechanism for office paper processing includes a slitting machine 100, a longitudinal slitting component, a transverse slitting component, and a drive motor 400. First, the slitting machine 100 is provided with a longitudinal slitting component, which includes a rotating shaft 201, a longitudinal slitting disc 202, and conveying wheels 203. That is, a rotating shaft 201 is rotatably connected to the slitting machine 100, and multiple sets of conveying wheels 203 are fixedly connected to the rotating shaft 201. A set of longitudinal slitting discs 202 is fixedly connected between every two sets of conveying wheels 203 on the rotating shaft 201. When the rotating shaft 201 rotates, the conveying wheels 203 and the longitudinal slitting discs 202 will rotate. When the raw paper is fed into the slitting machine 100, the rotating conveying wheels 203 can transport the raw paper, and at the same time, the rotating longitudinal slitting discs 202 can cut the raw paper into transverse strips.

[0024] Secondly, a cross-cutting component is provided on the slitting machine 100 after the longitudinal cutting component. The cross-cutting component includes a guide frame 301, a lifting platform 302, a rotating disk 303, and a cross-cutting blade 304. That is, the guide frame 301 is fixedly connected to the slitting machine 100, and the lifting platform 302 is slidably connected to the guide frame 301. Specifically, the guide frame 301 includes a fixed frame 3011 and a guide column 3012 fixedly connected to the fixed frame 3011. The fixed frame 3011 is fixedly connected to the slitting machine 100, and the lifting platform 302 is slidably connected to the guide column 3012. A cross-cutting blade 304 is fixedly connected to the bottom of the lifting platform 302. The cross-cutting blade 304 mates with the end face of the slitting machine platform 100. Furthermore, a rotating disk 303 is rotatably connected to the fixed frame 3011. That is to say, an input shaft 305 is fixedly connected to the rotating disk 303. The input shaft 305 is rotatably connected to the guide frame 301. In addition, an eccentric shaft 306 is fixedly connected to the rotating disk 303. A traction arm 307 is rotatably connected to the eccentric shaft 306. A traction shaft 308 is fixedly connected to the lifting platform 302. The end of the traction arm 307 is rotatably connected to the traction shaft 308.

[0025] Furthermore, a drive motor 400 is fixedly connected to the slitting machine 100. The drive motor 400 is powered by the rotating disk 303 and the rotating shaft 201 through a linkage component. In this embodiment, the linkage component includes an output gear 501, an input gear 502, and a transmission assembly. That is, an output shaft 503 is rotatably connected to the slitting machine 100, and an output gear 501 is fixedly connected to the output shaft 503. The output gear 501 is powered by the drive motor 400, and the output gear 501 is provided with a toothed portion 5011 (a portion of the area is without teeth).

[0026] At this time, an input gear 502 is fixedly connected to the aforementioned rotating shaft 201. The input gear 502 meshes with the output gear 501 (with teeth). Furthermore, the output shaft 503 and the rotating disk 303 are connected by a transmission assembly.

[0027] The transmission assembly includes a drive pulley 504, a driven pulley 505, and a transmission belt 506. Specifically, the driven pulley 505 is fixedly connected to the input shaft 305, the drive pulley 504 is fixedly connected to the output shaft 503, and the drive pulley 504 and the driven pulley 505 are connected by the transmission belt 506.

[0028] When the drive motor 400 drives the output gear 501 to rotate, the output gear 501 can drive the input gear 502 to rotate, so the rotating shaft 201 can rotate. At this time, the conveyor wheel 203 conveys the raw paper, and the longitudinal cutting disc 202 cuts the raw paper longitudinally. When the missing tooth part 5011 of the output gear 501 reaches the input gear 502, the output gear 501 cannot drive the input gear 502 to rotate, so the rotating shaft 201 does not rotate, and thus the raw paper is not conveyed.

[0029] When the drive motor 400 drives the output gear 501 to rotate, the transmission assembly can drive the rotating disk 303 to rotate. When the rotating disk 303 rotates, under the traction of the traction arm 307, the lifting platform 302 can drive the cross-cutting blade 304 to perform reciprocating lifting motion. After the cross-cutting blade 304 descends, it can cut the longitudinally cut raw paper to form the required A3 or A4 office paper.

[0030] In summary, this embodiment discloses an automatic slitting mechanism for office paper processing, which is mainly used to cut raw paper into the required office paper, such as A3 and A4 paper. The specific cutting method is as follows:

[0031] 1. Paper feeding and slitting:

[0032] After the raw paper enters the slitting machine 100, the drive motor 400 drives the output gear 501 to rotate, which in turn drives the input gear 502, causing the rotating shaft 201 to rotate. At this time, the conveyor wheel 203 continuously conveys the raw paper, and the rotating longitudinal cutting disc 202 evenly divides the raw paper into multiple horizontal strips.

[0033] 2. Fixed-length conveying and cross-cutting triggering

[0034] The strip-shaped raw paper is conveyed forward. When it reaches the preset length, the toothed part 5011 of the output gear 501 engages with the input gear 502. At this time, the conveyor wheel 203 stops rotating and the raw paper stops being conveyed. However, the drive motor 400 still drives the rotating disk 303 to rotate through the transmission assembly, causing the lifting platform 302 to descend. The cross-cutting blade 304 cuts the stationary raw paper horizontally.

[0035] 3. Cross-cutting completed and repositioned

[0036] After the cross-cutting is completed, the drive motor 400 continues to run, and the rotating disk 303 drives the cross-cutting blade 304 to rise and reset. When the cross-cutting blade 304 rises to a safe height (forming a sufficient conveying gap with the machine), the teeth of the output gear 501 re-mesh the input gear 502, the conveying wheel 203 resumes rotation, and the longitudinal cutting disk 202 continues to cut the raw paper, entering the next working cycle.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
