Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a corrugated paperboard production paper cutter. Background Art

[0002] Corrugated paper is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated board and double corrugated board. According to the size of the corrugation, it is divided into five types: A, B, C, E, and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] When the existing corrugated cardboard production paper cutter cuts paper, the cut paper often lacks guidance and scatters to both sides, and even the paper at the back is brought into the finished product frame due to the excessive cutting speed, affecting the subsequent sorting and statistics. Since the machine itself is small in size, the use of a larger separation device greatly increases the cost. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a corrugated board production paper cutter to solve the technical problem that the cut paper often lacks guidance and scatters to both sides.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corrugated cardboard production paper cutter, comprising a base, a support shaft is fixedly connected to the rear of the base, an adjustment mechanism is sleeved on the support shaft, the adjustment mechanism comprises an adjustment plate, a mounting groove is opened on the adjustment plate, a spring is fixedly connected to one side of the inner wall of the mounting groove, a push block is fixedly connected to one end of the spring, one side of the push block is an arc surface, and the arc surface is adapted to the support shaft.

[0006] By adopting the above technical solution, the base serves as the basic structure of the machine, providing a stable support and a fixed platform for the entire equipment, ensuring the stability and reliability of the equipment during operation. The support shaft serves as the supporting point of the adjustment mechanism, which not only ensures the accurate position of the adjustment mechanism, but also enables the adjustment mechanism to smoothly adjust the position and angle to adapt to corrugated cardboards of different sizes and shapes. The adjustment mechanism allows the operator to adjust the angle and position of the separated cut corrugated cardboard and waste as needed. The adjustment plate, as a part of the adjustment mechanism, can guide the cut cardboard to enter the next process correctly and block the waste cardboard to ensure work efficiency and accuracy. The mounting groove and spring enable the adjustment plate to be automatically locked, improving the overall firmness. The push block and the curved surface enhance the operational flexibility and accuracy of the machine. The push block helps the adjustment plate to remain tight, while the curved surface design ensures smooth cooperation with the support shaft and improves friction.

[0007] Furthermore, both sides of the mounting groove are provided with rounded corners, and one end of the adjustment plate is provided with a chamfer.

[0008] By adopting the above technical solutions, the rounded corner design reduces the potential risks brought by sharp corners. In mechanical operation, the rounded corners can reduce the risk of injury to operators and other components when they come into contact with the machine. The rounded corners can also help reduce stress concentration in materials and improve the durability and reliability of the structure. In a dynamic working environment, this design can reduce wear and damage caused by long-term operation. The chamfer is mainly used to guide the cut corrugated cardboard to flow smoothly to the recycling area.

[0009] Furthermore, a gearbox is fixedly connected to one side of the base, and a motor is fixedly connected to one side of the gearbox.

[0010] By adopting the above technical solution, the gearbox adjusts and transmits the power generated by the motor so as to control the speed and torque of the paper cutter. This adjustment capability enables the machine to adapt to corrugated cardboard of different thicknesses and hardnesses, as well as adjust the cutting speed according to production needs. The existence of the gearbox ensures the flexibility and adaptability of the machine during operation, thereby improving production efficiency and product quality. The motor is the power source of the entire paper cutter. It provides the required power to each component of the machine, so that the cutting operation can proceed smoothly.

[0011] Furthermore, a handle is slidably connected to the front side of the gearbox, and a first rotating shaft and a second rotating shaft are provided on the other side of the gearbox.

[0012] By adopting the above technical solution, the setting of the handle makes it convenient for the operator to adjust the opening and mode of the gearbox. By sliding the handle, the operator can easily adjust the setting of the gearbox to change the speed and torque of the paper cutter, making the operation of the machine more flexible, adjusting the cutting speed to adapt to corrugated cardboard of different thickness or hardness, and then quickly adapting to different production needs. The first rotating shaft and the second rotating shaft are used to drive the cutting knife to ensure the smoothness and accuracy of the cutting process.

[0013] Furthermore, a cutter frame is sleeved on the outer surfaces of the first rotating shaft and the second rotating shaft, and a cutter is fixedly connected to one side of the cutter frame.

[0014] By adopting the above technical solution, the cutter frame serves as a structure for supporting and fixing the cutter, ensuring the stability and accuracy of the cutter during the installation process. By installing the cutter frame on the rotating shaft, it can be ensured that the cutter cuts at a uniform speed and force, thereby improving the uniformity and accuracy of the cutting. In addition, the cutter frame also allows the cutter to be adjusted or replaced when necessary, improving the maintenance and operation flexibility of the equipment. The cutter fixed on the cutter frame can accurately cut corrugated cardboard.

[0015] Furthermore, a plurality of the adjustment mechanisms are provided, and the plurality of the adjustment mechanisms are linearly and evenly arranged along the center line of the support shaft.

[0016] By adopting the above technical solution, a wider and more flexible adjustment range can be provided by evenly arranging multiple adjustment mechanisms on the support shaft, which allows the machine to more accurately control the guidance and positioning of corrugated cardboards of different widths during the separation process, thereby adapting to cardboards of different sizes and shapes. Multiple evenly arranged adjustment mechanisms provide greater flexibility and adjustment capabilities.

[0017] Furthermore, the support shaft is provided with a tooth groove, and a plurality of the tooth grooves are provided, and the plurality of tooth grooves are evenly distributed in a ring shape.

[0018] By adopting the above technical solution, the role of the tooth grooves on the support shaft is mainly to provide stable and precise positioning points for the adjustment mechanism, and the annular uniform distribution of the tooth grooves ensures that the adjustment mechanism can be fixed in multiple positions.

[0019] Furthermore, a latching tooth is fixedly connected to the surface of the arc surface, and the latching tooth and the tooth groove are matched.

[0020] By adopting the above technical solution, the matching design of the latch teeth and the tooth grooves allows the adjustment mechanism to be accurately positioned on the support shaft. This matching ensures that the adjustment mechanism will not slide or move during operation, thereby maintaining the installation accuracy.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model sets a base, a support shaft and an adjustment mechanism. Before cutting the corrugated cardboard, the position and angle of the adjustment mechanism are adjusted, so that the corrugated cardboard cut from the first rotating shaft and the second rotating shaft is deflected by the adjustment plate at different angles when moving backward, so that the required cardboard enters the next process, and the waste cardboard is blocked by the adjustment plate with a larger elevation angle and falls into the recovery bin below, which is convenient for adapting to different cutting sizes and solves the technical problem that the cut paper often lacks guidance and scatters to both sides.

[0023] 2. The utility model provides rounded corners and chamfers. The rounded corners can facilitate the clamping of the adjustment mechanism. At the same time, the chamfer at the front end can facilitate the downward guidance of the cut corrugated paper, thereby completing the recycling function.

[0024] 3. The utility model provides tooth grooves and latch teeth, and utilizes the tooth grooves and latch teeth to enable the adjustment mechanism to be stably clamped on the support shaft, thereby preventing the adjustment mechanism from deflecting due to gravity and the impact force of the cardboard, thereby preventing the separation effect from being ineffective.

The matching design of the latch tooth 11 and the tooth groove 10 allows the adjustment mechanism 9 to be accurately positioned on the support shaft 8. This cooperation ensures that the adjustment mechanism 9 will not slide or move during operation, thereby maintaining the installation accuracy. When the latch tooth 11 and the tooth groove 10 are engaged with each other, they jointly bear the force generated during the operation, which helps to disperse the pressure and reduce the burden of a single component. It can reduce the misalignment of the adjustment mechanism 9 caused by vibration or mechanical stress, increase the overall accuracy and efficiency of the machine, and make it easier and faster to adjust the position of the adjustment mechanism 9.

[0043] The implementation principle of the utility model is: first, the adjustment mechanism 9 is inserted into the support shaft 8, the locking teeth 11 and the locking groove are clamped together, and then the adjustment plate 901 is rotated. At this time, the push block 904 moves to one side, and then the tooth groove 10 and the locking teeth 11 are separated from each other, creating space to facilitate the rotation of the adjustment plate 901. After the position is adjusted, the push block 904 is reset to make the tooth groove 10 and the locking teeth 11 re-engage, so that the paper cutter separation operation can be performed.
