Description

Technical Field

[0001] This utility model relates to the field of paper tube cutting technology, and more specifically, to a fully automatic CNC paper tube cutting machine. Background Technology

[0002] Paper tube production typically involves long blanks. For example, when paper tubes are wound and formed using a paper tube machine, long tubes of 1-5 meters are first produced to improve production efficiency. However, downstream applications require paper tubes of specific sizes, so the paper tubes need to be cut to fit the actual usage requirements. During the cutting process, CNC cutting equipment is generally used to process the continuously produced long paper tube blanks into finished paper tubes of specific lengths that meet the needs of downstream applications.

[0003] Existing CNC cutting equipment cuts paper tubes with a cutter and then discharges the cut paper tubes through a guide hopper. However, the guide hoppers of traditional paper tube sorting equipment are mostly of fixed size and can only accommodate paper tubes of a single specification. If the diameter of the paper tube is too small, it is easy for it to shake or get stuck in the channel; if the diameter is too large, the paper tube cannot pass through the guide hopper, resulting in sorting failure. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fully automatic CNC paper tube cutting machine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic CNC paper tube cutting machine, comprising a mounting frame, a spindle rotation mechanism, and a cutting tool feeding mechanism. The spindle rotation mechanism, the cutting tool feeding mechanism, and the tube feeding mechanism are all fixedly mounted on the mounting frame. The cutting tool feeding mechanism is located behind the spindle rotation mechanism, and the tube feeding mechanism is located at the bottom of the spindle rotation mechanism. A guide hopper is fixedly mounted on the mounting frame, and a connecting box is provided on the guide hopper. An adjustment assembly is provided on the connecting box. The adjustment assembly includes a positive and negative lead screw, two sliders, two baffles, two slide rods, a bevel gear assembly, a stepper motor, and two second buffer pads. The front and rear ends of the positive and negative lead screws are movably connected to the connecting box through bearings. The two sliders are threadedly connected to the positive and negative lead screws, and the bottom ends of the two baffles are fixedly connected to the two sliders respectively.

[0006] Furthermore, the stepper motor is fixedly installed at the bottom of the connecting box, and the output shaft of the stepper motor is connected to the forward and reverse lead screws through a bevel gear assembly.

[0007] Furthermore, both ends of the two slide rods are fixedly connected to the connecting box, and both slide rods pass through the two sliders.

[0008] As can be seen, in the above technical solution, the two sliding rods restrict the rotation of the two sliders.

[0009] Furthermore, the two second buffer pads are fixedly connected to two baffles on opposite sides, and the top of the connecting box is fixedly connected to a first buffer pad.

[0010] As can be seen, in the above technical solution, the second buffer pad and the first buffer pad can buffer the paper tube.

[0011] Furthermore, three lead screws are fixedly connected to the bottom of the connecting box, and the bottom ends of the three lead screws all penetrate the guide hopper, with nuts movably sleeved on the outer sides of the three lead screws.

[0012] As can be seen, in the above technical solution, the three nuts are rotated in sequence and brought into contact with the guide hopper, thereby fixing the connecting box and the guide hopper together.

[0013] Furthermore, the mounting frame is equipped with a feeding assembly, which includes a material bin, a material lifting and conveying chain, and a pipe-pulling mechanism.

[0014] Furthermore, the material bin, the material lifting conveyor chain, and the tube-shifting mechanism are all fixedly installed on the mounting frame. The material lifting conveyor chain is located on the front side of the material bin, the tube-shifting mechanism is located on the top of the material lifting conveyor chain, and the tube-shifting mechanism is located on one side of the main shaft rotation mechanism.

[0015] The technical effects and advantages of this utility model are as follows: 1. This utility model places the connecting box inside the guide hopper, and the stepper motor drives the positive and negative lead screws to rotate through the bevel gear assembly. The positive and negative lead screws can drive two sliders, two baffles and two second buffer pads to move in opposite directions. The position of the two baffles can be adjusted according to the needs. The paper tube is guided by the guide hopper, connecting box and two baffles. The operation is simple and can guide paper tubes of different diameters. It has a wide range of applications. 2. This utility model continuously lifts the billet to the feed port of the tube-pulling mechanism through a material lifting and conveying chain. The tube-pulling mechanism precisely guides a single billet to the feed end of the main shaft rotation mechanism through a pneumatic push rod. The working parameters of the cutting feed mechanism are preset in the control system. The main shaft rotation mechanism drives the paper tube to rotate at high speed, and the cutting feed mechanism drives the cutter to feed smoothly in the radial direction, contacting the rotating paper tube to complete the cutting. The structure is simple and can automatically cut the paper tube. Attached Figure Description

[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Refer to the instruction manual appendix Figure 1-5This embodiment of a fully automatic CNC paper tube cutting machine includes a mounting frame 1, a spindle rotation mechanism 2, and a cutter feeding mechanism 3. The spindle rotation mechanism 2, the cutter feeding mechanism 3, and the tube feeding mechanism 4 are all fixedly mounted on the mounting frame 1. The cutter feeding mechanism 3 is located behind the spindle rotation mechanism 2, and the tube feeding mechanism 4 is located at the bottom of the spindle rotation mechanism 2. A guide hopper 5 is fixedly mounted on the mounting frame 1. A connecting box 10 is provided on the guide hopper 5. An adjustment component 9 is provided on the connecting box 10. The adjustment component 9 includes a positive and negative lead screw 901, two sliders 902, two baffles 903, two slide rods 904, a bevel gear assembly 905, a stepper motor 906, and two second buffer pads 907. The front and rear ends of the positive and negative lead screw 901 are movably connected to the connecting box 10 through bearings. The two sliders 902 are threadedly connected to the positive and negative lead screw 901. The bottom ends of the two baffles 903 are fixedly connected to the two sliders 902 respectively.

[0021] like Figure 4-5 As shown, the stepper motor 906 is fixedly installed at the bottom of the connecting box 10, and the output shaft of the stepper motor 906 is connected to the forward and reverse lead screw 901 through the bevel gear assembly 905. The front and rear ends of the two slide rods 904 are fixedly connected to the connecting box 10, and the two slide rods 904 pass through the two sliders 902.

[0022] like Figure 2-5 As shown, the two second buffer pads 907 are fixedly connected to the two baffles 903 on opposite sides, and the first buffer pad 11 is fixedly connected to the top of the connecting box 10.

[0023] like Figure 3 As shown, three lead screws 12 are fixedly connected to the bottom of the connecting box 10, and the bottom ends of the three lead screws 12 all penetrate the guide hopper 5. Nuts 13 are movably sleeved on the outer side of the three lead screws 12.

[0024] like Figure 1 As shown, a feeding assembly is provided on the mounting frame 1. The feeding assembly includes a material bin 6, a material lifting conveyor chain 7, and a tube-pulling mechanism 8. The material bin 6, the material lifting conveyor chain 7, and the tube-pulling mechanism 8 are all fixedly installed on the mounting frame 1. The material lifting conveyor chain 7 is located in front of the material bin 6, and the tube-pulling mechanism 8 is located at the top of the material lifting conveyor chain 7. The tube-pulling mechanism 8 is located on one side of the main shaft rotation mechanism 2.

[0025] In this system, paper tube blanks to be cut are neatly stacked in the material bin 6 in advance. The blanks are continuously lifted to the feed port of the tube-pushing mechanism 8 by the material lifting conveyor chain 7. The tube-pushing mechanism 8 uses a pneumatic push rod to precisely guide a single blank to the feed end of the main shaft rotation mechanism 2. At the same time, the conveying rollers of the tube-walking mechanism 4 hold the blank and push it axially, sending it into the chuck of the main shaft rotation mechanism 2. The chuck concentrically clamps and fixes the paper tube. According to the required paper tube width, the working parameters of the cutting knife feeding mechanism 3 are preset in the control system, including the cutting speed, feed amount and the lateral movement distance of the cutting knife driven by the servo motor. After the equipment is started, the main shaft rotation mechanism 2 drives the paper tube to rotate at high speed. The cutting knife feeding mechanism 3 drives the cutting knife to feed smoothly radially and contact the rotating paper tube to complete the cutting. The structure is simple and can automatically cut paper tubes.

[0026] The usage method of this embodiment is as follows: In use, the connecting box 10 is placed inside the guide hopper 5, with all three lead screws 12 passing through the guide hopper 5. Then, the three nuts 13 are rotated sequentially until they contact the guide hopper 5, thus fixing the connecting box 10 to the guide hopper 5. The stepper motor 906 is then started. The stepper motor 906 drives the forward and reverse lead screws 901 to rotate via the bevel gear assembly 905. It is worth noting that the bevel gear assembly 905 includes two bevel gears, which are respectively fixedly connected to the output shaft of the stepper motor 906 and the forward and reverse lead screws 901. Since both sliders 902 are connected to the forward and reverse lead screws 901... 01. Threaded connection. Two slide rods 904 restrict the rotation of two sliders 902. Therefore, the forward and reverse screws 901 can drive the two sliders 902, two baffles 903, and two second buffer pads 907 to move in opposite directions. The position of the two baffles 903 can be adjusted as needed. The paper tube is guided by the guide hopper 5, connecting box 10, and two baffles 903. The operation is simple and can guide paper tubes of different diameters. It has a wide range of applications. At the same time, the second buffer pads 907 and the first buffer pads 11 can buffer the paper tube. It is worth noting that the stepper motor 906 has a built-in electromagnetic locking mechanism.
