TECHNICAL FIELD
[0001] The utility model relates to a paper cutting machine technical field especially relates to an automatic paper cutting machine. BACKGROUND
[0002] In the paper manufacturing process, in order to improve production efficiency and ensure the quality standard of paper, manufacturers usually produce paper into large spool. Subsequently, using paper sawing machine equipment, these large spool paper is cut into wide paper. Then, according to the specific needs of actual application, using paper cutting machine further cuts these wide paper into the required size.
[0003] The paper cutting machine is a mechanical equipment specially designed for accurate cutting of books, paper and other similar materials. When handling a large number of stacked paper, the equipment can meet the needs of neat cutting and one-time completion of multi-layer paper cutting, and is an indispensable part of the paper production process. Although the existing paper cutting machine has realized automation in the cutting process, the paper to be cut still needs to be manually fed into the cutting system before each cutting operation. This manual feeding method not only may lead to insufficient accuracy of the cutting position, thereby affecting the standardized production of paper, but also has relatively low production efficiency. SUMMARY
[0004] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide an automatic paper cutting machine. The scheme can accurately position the paper for cutting, thereby ensuring the accuracy of the cutting position and meeting the needs of standardized paper production.
[0005] To solve the above technical problems, the utility model provides an automatic paper cutting machine, which adopts the following technical scheme:
[0006] An automatic paper cutting machine, comprising a cutting assembly and a rack, the cutting assembly is fixedly installed on the rack, further comprising a feeding mechanism, the feeding mechanism is arranged below the cutting assembly, the feeding mechanism comprises a conveying device, a load plate and a positioning piece, a plurality of pushers are fixedly arranged on the conveying device, the plurality of pushers are arranged on the same horizontal line, the load plate is fixedly installed on the rack, a plurality of slots are arranged on the load plate, the pushers are in sliding cooperation with the slots, and the positioning piece is arranged on one side of the cutting assembly and is rotatably connected with the load plate.
[0007] With this structure, by integrating the feeding mechanism, especially the conveying device equipped with the pushing element, the continuous and smooth feeding of the paper is realized, and at the same time, the cooperation of the positioning element is realized. Compared with the traditional manual feeding, this mechanical feeding method is beneficial to send the paper to be cut to the specified position, thereby ensuring the cutting accuracy, making the cut paper size more in line with the requirements, and improving the cutting efficiency. In addition, due to the design of the slot on the loading plate and the flexibility of the pushing element and the positioning element, the automatic paper cutting machine can adapt to the cutting needs of paper of various sizes and types, showing good adaptability and flexibility.
[0008] Further, the cutting assembly includes a cutting mechanism and a fixing mechanism, both of which are fixed on the rack, so the fixing mechanism is arranged on one side of the cutting mechanism. The existence of the fixing mechanism ensures the stability of the object to be cut during the cutting process, avoids cutting errors caused by object movement or shaking, and thus improves the cutting accuracy and overall operation efficiency. At the same time, the cutting mechanism and the fixing mechanism are both fixed on the rack, and the fixing mechanism is arranged on one side of the cutting mechanism. This compact layout design makes the entire cutting assembly more tidy and orderly, facilitating maintenance and operation.
[0009] As a preferred, the cutting mechanism includes a support rod, a first cam, a second cam, two connecting rods, a cutter head and a driving motor, the support rod is arranged on the rack, the support rod is connected with the driving motor, the driving motor can drive the support rod to rotate, the first cam and the second cam are respectively fixedly installed at both ends of the support rod, one end of the two connecting rods is respectively fixedly connected with the flanges of the first cam and the second cam, the radius of the first cam is larger than that of the second cam, and the cutter head is fixedly connected with the other end of the connecting rod. The motor is directly connected with the support rod, which can efficiently transmit the rotating power of the motor to the support rod. This direct connection method reduces energy loss and improves cutting efficiency. The first cam and the second cam with different radii can produce different displacement amounts, so that the cutter head has a certain inclination angle with the paper during cutting. Thus, the contact area between the cutter head and the paper is smaller when the cutter head is lowered, thereby increasing the contact area pressure and making the cutting more smooth, and the edges of the cut paper are not easy to produce burrs.
[0010] As a preferred, the fixing mechanism includes a lifting assembly and a paper pressing plate, the paper pressing plate can move vertically under the driving of the lifting assembly. The paper pressing plate can apply uniform and stable pressure under the precise control of the lifting assembly, ensuring that the fixed paper will not be displaced or loose due to external factors. At the same time, this design has high flexibility and can be applied to paper materials of different thicknesses or sizes.
[0011] As preferred, the bottom of the paper pressing plate is provided with a plurality of protrusions, which are arranged at intervals along the paper pressing plate. The design of the protrusions increases the friction between the paper pressing plate and the fixed paper, so that the paper pressing plate can more firmly fix the paper or material when pressure is applied, preventing it from sliding or shifting.
[0012] As preferred, two clamping devices are further included, which are symmetrically arranged on both sides of the cutting assembly and above the material loading plate. The clamping device includes a driving member and a clamping block fixedly installed on the inner side of the driving member, and the clamping block can move horizontally under the drive of the driving member. The clamping device drives the clamping block to move horizontally through the driving member, which can quickly and accurately clamp and release the material, so as to realize accurate clamping of the paper. In this way, the material can be kept stable during cutting, avoiding cutting errors caused by movement or shaking of the material, thereby improving cutting accuracy.
[0013] As preferred, an edge pressing device is further included, which is arranged between the cutting assembly and the feeding mechanism. The edge pressing device includes two flexible plates and a fixing member, and the fixing member is fixedly connected with the rack. The two flexible plates are arranged at intervals on the fixing member. Since the paper is light, the edge may be raised during feeding. The arrangement of the edge pressing device fixes the edge, preventing cutting errors caused by movement or shaking of the material during cutting. The flexible plate can be made of light and tough metal material, which can not only achieve good edge pressing effect but also will not cause damage to the paper.
[0014] As preferred, a knife falling groove is further included, which is arranged directly below the knife head and fixed with the material loading plate. During cutting, the knife head acts directly in the knife falling groove instead of directly impacting the surface of the material loading plate, which helps to reduce the wear of the knife head, and the paper close to the material loading plate will not have burrs on the cutting edge due to the impact of the knife head and the material loading plate
[0015] In summary, the automatic paper cutting machine can accurately position the paper for cutting, ensuring the accuracy of the cutting position and meeting the needs of standardized paper production. BRIEF DESCRIPTION OF DRAWINGS
