[0004] In the existing planned data, the cutting of cardboard is mainly realized by the rotation of the creasing wheels on the rotating shaft. During the production process, the cutting size of the cardboard is not a single fixed value. When changing the cutting size of the cardboard, the distance between two adjacent creasing wheels needs to be adjusted. However, the creasing wheels and the rotating shaft are fixedly installed, which causes certain disadvantages in the process of changing the production size, and the production flexibility is poor, and there is a certain space for optimization.

[0005] Therefore, we propose a paper separating and creasing machine for carton production. Summary of the Utility Model

[0006] The utility model mainly solves the technical problem that the fixed distance between the creasing wheels restricts the production flexibility, and provides a paper separating and creasing machine for carton production.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme. A paper separating and creasing machine for carton production includes:

[0008] A frame, which is a frame structure for support;

[0009] A rotating shaft, which is rotatably connected to the wall surface of the frame, and two mutually driving rotating shafts are arranged on the wall surface of the frame;

[0010] A creasing wheel, which is arranged on the wall surface of the rotating shaft for cutting the cardboard, and the creasing wheel can slide along the rotating shaft to adjust its position;

[0011] A limiting component is arranged between the rotating shaft and the wire pressing wheel for adjusting and locking the position of the wire pressing wheel. The limiting component includes a positioning hole and a stop push rod. A plurality of positioning holes are formed on the wall surface of the rotating shaft. The stop push rod is elastically connected to the wire pressing wheel. The positioning hole can be snapped into the positioning hole to lock the position of the wire pressing wheel. A plurality of identical wire pressing wheels are arranged on the wall surface of the rotating shaft, and the same stop push rod is arranged on the wall surface of each wire pressing wheel to individually adjust the position of each positioning hole.

[0012] As a preferred embodiment of the present invention, the stop push rod forms a rectangular columnar structure, and the positioning hole forms a rectangular notch adapted to the stop push rod.

[0013] As a preferred embodiment of the present invention, the rotating shaft forms a rod structure with a D-shaped cross section. The top surface of the rotating shaft forms a plane, and the positioning hole is opened on the plane of the rotating shaft. The positioning holes are linearly distributed at the top of the rotating shaft.

[0014] As a preferred embodiment of the present invention, the limiting component further includes a sliding channel. The stop push rod is located in the sliding channel, and an elastic member is arranged in the sliding channel to push the stop push rod against the rotating shaft.

[0015] As a preferred embodiment of the present invention, the sliding channel forms a notch adapted to the stop push rod. The stop push rod is slidably connected to the sliding channel. The elastic member is arranged at the top of the stop push rod. The elastic member includes a spring but is not limited to a spring. The two ends of the spring are respectively fixed to the stop push rod and the inner wall surface of the wire pressing wheel.

[0016] As a preferred embodiment of the present invention, the limiting component further includes a dial rod and a side groove. A side groove communicating with the sliding channel is opened on the wall surface of the wire pressing wheel. The dial rod passes through the side groove and is connected to the stop push rod. The dial rod can push the stop push rod to slide.

[0017] As a preferred embodiment of the present invention, the dial rod is a rectangular rod. The end of the dial rod is fixedly connected to one side of the stop push rod. The side groove has the same width as the dial rod, and the height of the side groove is greater than the thickness of the dial rod. When the stop push rod completely slides into the sliding channel, there is a gap between the top surface of the dial rod and the inner top surface of the wire pressing wheel.

[0018] Beneficial effects

[0019] The present invention provides a paper splitting and wire pressing machine for carton production. It has the following beneficial effects:

[0020] 1. The paper separating and creasing machine for carton production can be detached from the positioning hole by pushing the stop push rod upward, and the creasing wheel can be pulled along the rotating shaft to adjust the position. Thus, the distance between two adjacent creasing wheels can be adjusted, and then the width of the cardboard cut by the two creasing wheels can be adjusted. The chamfer on the circumferential surface of the creasing wheel forms a cutting edge for easy cutting. It can be flexibly adjusted according to production requirements, and the adjustment method is simple and fast, which is beneficial to actual production applications.

[0021] 2. The paper separating and creasing machine for carton production realizes the elastic connection of the stop push rod by sliding the stop push rod in the sliding channel and squeezing the spring. After the creasing wheel slides to the predetermined position, the spring can push the stop push rod to slide downward in the sliding channel and insert it into the positioning hole at the corresponding position, realizing the position locking of the creasing wheel and keeping synchronous rotation with the rotating shaft, simplifying the steps of adjusting the position of the creasing wheel and locking the creasing wheel, and making it more convenient and flexible to use.

[0022] 3. The paper separating and creasing machine for carton production is provided with a lever. When the position of the creasing wheel needs to be adjusted, the lever can be pushed to drive the stop push rod to slide, thereby releasing the locking of the creasing wheel. The side groove can limit the lever to prevent the lever from shifting, thereby ensuring the stability of the sliding of the stop push rod. On the basis of ensuring that the stop push rod can be easily inserted into the positioning hole, the method of releasing the locking of the creasing wheel by the stop push rod is more convenient, and only the lever needs to be pushed.

[0029] A paper separating and creasing machine for carton production, as Figure 1 and Figure 2 shown, includes:

[0030] A frame 10 for supporting;

[0031] The rotating shaft 11 is rotatably connected to the wall surface of the frame 10. There are two mutually driving rotating shafts 11 provided on the wall surface of the frame 10. Specifically, driven gears are fixedly connected to the ends of the two rotating shafts 11. A motor is fixedly installed on one side of the frame 10, and a driving gear is fixedly installed on the output shaft of the motor. The driving gear meshes with the two driven gears at the same time. A control box for controlling the motor is also installed on one side of the frame 10, which will not be elaborated here;

[0032] As Figure 2 , Figure 3 and Figure 4 shown, the pressing wheel 12 is arranged on the wall surface of the rotating shaft 11 for cutting the cardboard. The pressing wheel 12 can slide along the rotating shaft 11 to adjust its position. The limiting component is arranged between the rotating shaft 11 and the pressing wheel 12 for adjusting and locking the position of the pressing wheel 12. The limiting component includes a positioning hole 20 and a stop push rod 21. A number of positioning holes 20 are opened on the wall surface of the rotating shaft 11. The stop push rod 21 is elastically connected to the pressing wheel 12. The positioning hole 20 can be inserted into the positioning hole 20 to lock the position of the pressing wheel 12. A number of identical pressing wheels 12 are arranged on the wall surface of the rotating shaft 11, and the same stop push rod 21 is arranged on the wall surface of each pressing wheel 12 to individually adjust the position of each positioning hole 20. The stop push rod 21 forms a rectangular columnar structure, and the positioning hole 20 forms a rectangular notch adapted to the stop push rod 21. The rotating shaft 11 forms a rod-shaped structure with a D-shaped cross section. The top surface of the rotating shaft 11 forms a plane, and the positioning hole 20 is opened on the plane of the rotating shaft 11. The positioning holes 20 are linearly distributed at the top of the rotating shaft 11. In this solution, by pushing the stop push rod 21 upward to disengage from the positioning hole 20 and pulling the pressing wheel 12 to adjust its position along the rotating shaft 11, the distance between two adjacent pressing wheels 12 can be adjusted, and then the width of the cardboard cut by the two pressing wheels 12 can be adjusted. The circumferential surface of the pressing wheel 12 is chamfered to form a cutting edge for easy cutting, which can be flexibly adjusted according to production requirements. The adjustment method is simple and fast, which is beneficial to actual production applications.

[0033] As Figure 5 shown, the limiting component further includes a sliding channel 22. The stop push rod 21 is located in the sliding channel 22. An elastic member is arranged in the sliding channel 22 for pushing the stop push rod 21 to abut against the rotating shaft 11. The sliding channel 22 forms a notch adapted to the stop push rod 21. The stop push rod 21 is slidably connected to the sliding channel 22. The elastic member is arranged at the top of the stop push rod 21. The elastic member includes a spring but is not limited to a spring. The two ends of the spring are respectively fixedly connected to the stop push rod 21 and the inner wall surface of the pressing wheel 12. The elastic connection of the stop push rod 21 is realized by the stop push rod 21 sliding in the sliding channel 22 and compressing the spring. After the pressing wheel 12 slides to a predetermined position, the spring can push the stop push rod 21 to slide down in the sliding channel 22 and insert into the corresponding positioning hole 20, so as to lock the position of the pressing wheel 12 and keep it rotating synchronously with the rotating shaft 11, simplifying the steps of adjusting the position of the pressing wheel 12 and locking the pressing wheel 12, and making it more convenient and flexible to use.

[0034] As shown Figure 5 in the figure, the limiting component further includes a lever 23 and a side groove 24. The side groove 24 communicating with the sliding channel 22 is formed on the wall surface of the wire pressing wheel 12. The lever 23 passes through the side groove 24 and is connected to the stop push rod 21. The lever 23 can push the stop push rod 21 to slide. The lever 23 is a rectangular rod body. The end of the lever 23 is fixedly connected to one side of the stop push rod 21. The side groove 24 has the same width as the lever 23, and the height of the side groove 24 is greater than the thickness of the lever 23. When the stop push rod 21 completely slides into the sliding channel 22, there is a gap between the top surface of the lever 23 and the inner top surface of the wire pressing wheel 12. As a supplement to the above solution, by setting the lever 23, when the position of the wire pressing wheel 12 needs to be adjusted, the lever 23 can be pushed to drive the stop push rod 21 to slide, thereby releasing the locking of the wire pressing wheel 12. The side groove 24 can limit the lever 23 to prevent the lever 23 from shifting, thereby ensuring the stability of the sliding of the stop push rod 21. On the basis of satisfying that the stop push rod 21 can be easily clamped into the positioning hole 20, the method of releasing the locking of the wire pressing wheel 12 by the stop push rod 21 is more convenient, and only the lever 23 needs to be pushed.

[0035] The working principle of the present utility model: Push the lever 23 to drive the stop push rod 21 to slide. The stop push rod 21 slides in the sliding channel 22 and squeezes the spring to realize the elastic connection of the stop push rod 21. After the wire pressing wheel 12 slides to the predetermined position, the spring can push the stop push rod 21 to slide down in the sliding channel 22 and insert into the positioning hole 20 at the corresponding position, realizing the position locking of the wire pressing wheel 12 and keeping synchronous rotation with the rotating shaft 11, realizing the position adjustment and locking of one wire pressing wheel 12. The distance between two adjacent wire pressing wheels 12 can be adjusted, and then the width of the cardboard cut by the two wire pressing wheels 12 can be adjusted. The circumferential surface of the wire pressing wheel 12 is chamfered to form a cutting edge for easy cutting;

[0036] Driven gears are fixedly connected to the ends of the two rotating shafts 11. A motor is fixedly installed on one side of the frame 10. The output shaft of the motor is fixedly installed with a driving gear. The driving gear is meshed with the two driven gears at the same time. A control box for controlling the motor is also installed on one side of the frame 10, which will not be elaborated here.
