TECHNICAL FIELD
[0001] The application relates to the technical field of paper box forming, in particular to a positioning paper feeding mechanism of a paper box forming machine. BACKGROUND
[0002] The paper box forming machine is a mechanical equipment widely applied to the packaging industry and mainly used for processing paper boards into paper boxes with specific shapes and specifications. In the paper box forming production process, the positioning paper feeding mechanism plays a crucial role, and the performance thereof directly influences the quality and production efficiency of the paper box forming.
[0003] In view of the above related technologies, the inventors consider that the positioning paper feeding mechanism of the paper box forming machine in the prior art has many problems to be solved. On the one hand, the traditional paper feeding mechanism lacks an effective tension adjusting device. With the paper feeding process, the paper is prone to relaxation, which causes the paper to wrinkle, deviate and other problems during the conveying, seriously influences the dimensional accuracy and appearance quality of the paper box forming, increases the rate of defective products, and on the other hand, the adaptability to paper with different widths is poor. When adjusting the paper conveying width, the existing positioning paper feeding mechanism is complicated to operate and has low precision, and a large amount of time is often spent on manual adjustment, which reduces the production efficiency and is difficult to meet diversified production demands. Therefore, the positioning paper feeding mechanism of the paper box forming machine is provided to solve the above problems. CONTENT OF THE UTILITY MODEL
[0004] In order to solve the problems in the background art, the positioning paper feeding mechanism of the paper box forming machine is provided.
[0005] The positioning paper feeding mechanism of the paper box forming machine provided by the application comprises a paper feeding table and a paper feeding assembly, the surface of the paper feeding table is fixedly connected with an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected with a tension adjusting block, the outer side of the tension adjusting block is fixedly connected with a tension adjusting rod, the surface of the paper feeding table is fixedly connected with two vertical plates, the outer side wall of one of the vertical plates is fixedly connected with a servo motor, the output end of the servo motor is fixedly connected with a bidirectional screw rod through a shaft coupling, the outer part of the bidirectional screw rod is symmetrically connected with two limiting plates in threads, and two guide rods are connected in an up-down rotation mode between the two vertical plates and directly below the bidirectional screw rod.
[0006] Preferably, the paper feeding assembly comprises a driving motor fixedly connected to one side edge of the paper feeding table, and the output end of the driving motor is fixedly connected with a paper feeding roller.
[0007] Preferably, the end of the tension adjusting rod away from the electric telescopic rod is rotationally connected with an auxiliary adjusting block, the inner part of the auxiliary adjusting block is slidably connected with a limiting rod, and the bottom end of the limiting rod is fixedly connected with the surface of the paper feeding table.

[0009] Preferably, the limiting plate penetrates the two guide rods.
[0010] In summary, the present application has the following beneficial technical effects:
[0011] 1. By setting the electric telescopic rod, the tension adjusting block and the tension adjusting rod, the tension of the paper can be accurately adjusted according to the actual paper feeding demand. When the paper is loose, the electric telescopic rod is elongated to push the tension adjusting block and the tension adjusting rod to move upward, thereby increasing the tension of the paper and ensuring that the paper remains flat during the conveying process, avoiding the phenomenon of wrinkles and deviation, thereby improving the quality and dimensional accuracy of the carton forming and reducing the rate of defective products. At the same time, the setting of the auxiliary adjusting block and the limiting rod ensures the stability and accuracy of the tension adjusting rod during the movement, further improving the effect of tension adjustment.
[0012] 2. The servo motor drives the bidirectional screw rod to rotate, which drives the two limiting plates to move symmetrically, so as to quickly and accurately adjust the distance between the limiting plates to adapt to the conveying demand of paper of different widths. This adjustment method is simple and convenient to operate, greatly saving the adjustment time and improving the production efficiency. Moreover, the limiting plate penetrates the two guide rods, which can guide and limit the paper during the adjustment of the width, preventing the lateral movement of the paper during the conveying process and ensuring the accuracy and stability of the paper feeding.

DETAILED DESCRIPTION
[0018] The application will be further described below in conjunction with the accompanying drawings. Figure 1 - Figure 4 The application will be further described below in conjunction with the accompanying drawings.
[0019] Embodiment I:
[0020] The positioning paper feeding mechanism of the carton forming machine, referring to Figure 1 - Figure 4 , includes a paper feeding table 1 and a paper feeding assembly. The surface of the paper feeding table 1 is fixedly connected with an electric telescopic rod 2. The output end of the electric telescopic rod 2 is fixedly connected with a tension adjusting block 3. The outer side of the tension adjusting block 3 is fixedly connected with a tension adjusting rod 4. When the electric telescopic rod 2 is started, the output end will perform telescopic movement. If the paper appears relaxation phenomenon in the conveying process, the electric telescopic rod 2 is elongated, pushing the tension adjusting block 3 fixedly connected therewith to move upward. Since the outer side of the tension adjusting block 3 is fixedly connected with the tension adjusting rod 4, the movement of the tension adjusting block 3 will drive the tension adjusting rod 4 to move upward together, thereby increasing the tension of the paper, so that the paper maintains a suitable tension state, avoiding the conveying problem caused by relaxation. The surface of the paper feeding table 1 is fixedly connected with two vertical plates 5. The outer side wall of one of the two vertical plates 5 is fixedly connected with a servo motor 6. The output end of the servo motor 6 is fixedly connected with a bidirectional screw rod 7 through a shaft coupling. The outer part of the bidirectional screw rod 7 is symmetrically connected with two limiting plates 8. Two guide rods 14 are connected in an up-down rotating manner between the two vertical plates 5 and directly below the bidirectional screw rod 7. When it is necessary to adjust the paper conveying width, the servo motor 6 is started, and the output end drives the bidirectional screw rod 7 to rotate through the shaft coupling. Due to the special screw thread structure of the bidirectional screw rod 7, the two limiting plates 8 connected with the outer part of the bidirectional screw rod 7 will move symmetrically towards or away from each other with the rotation of the bidirectional screw rod 7, thereby realizing the adjustment of the paper conveying width to adapt to the needs of different specifications of paper. The two guide rods 14 connected in an up-down rotating manner between the two vertical plates 5 and directly below the bidirectional screw rod 7 provide a guiding effect for the conveying of the paper, ensuring that the paper can be conveyed smoothly along the predetermined path.
[0021] Referring to Figure 1 , the paper feeding assembly includes a driving motor 9 fixedly connected to one side edge of the paper feeding table 1. The output end of the driving motor 9 is fixedly connected with a paper feeding roller 10. When the driving motor 9 is started, the output end begins to rotate. Since the output end is fixedly connected with the paper feeding roller 10, the paper feeding roller 10 will rotate together with the output end of the driving motor 9. There is a friction force between the paper feeding roller 10 and the paper. In the process of rotation of the paper feeding roller 10, this friction force will drive the paper wound outside the paper feeding roller 10 to convey forward, thereby realizing the movement of the paper from the paper feeding roller 10 to the subsequent processing link.
[0022] Referring to Figure 1 , Figure 3 and Figure 4, the auxiliary adjusting block 11 is rotationally connected to the end of the tension adjusting rod 4 away from the electric telescopic rod 2, the inside of the auxiliary adjusting block 11 is slidably connected with a limiting rod 12, the bottom end of the limiting rod 12 is fixedly connected with the surface of the paper feeding table 1, and the auxiliary adjusting block 11 can slide on the limiting rod 12 in the process of tension adjustment of the electric telescopic rod 2, the tension adjusting block 3 and the tension adjusting rod 4. The limiting rod 12 limits the movement track of the auxiliary adjusting block 11, thereby guaranteeing the stability and accuracy of the tension adjusting rod 4 in the movement process, can prevent the tension adjusting rod 4 from deviating or shaking in the adjustment process, makes the tension adjustment more accurate and reliable, and ensures the adjustment effect of the paper tension.
[0023] With reference to Figure 1 and Figure 3 , the outside of the paper feeding roller 10 is wound with a paper body 13, the paper body 13 sequentially passes through the gap between the upper arc surface of the tension adjusting rod 4 and the two guide rods 14, when the driving motor 9 drives the paper feeding roller 10 to rotate and convey the paper, the paper body 13 will first pass through the upper arc surface of the tension adjusting rod 4. The tension adjusting rod 4 can change the position according to the adjustment of the electric telescopic rod 2, so as to adjust the tension of the paper body 13, and then the paper body 13 will pass through the gap between the two guide rods 14. The two guide rods 14 play a guiding and limiting role on the paper body 13, so that the paper can be smoothly conveyed to the subsequent processing position along the correct direction, ensuring the accuracy and stability of the paper feeding process.
[0024] With reference to Figure 4 , the limiting plate 8 penetrates through the two guide rods 14, when the servo motor 6 drives the bidirectional screw rod 7 to rotate and drives the limiting plate 8 to move in the opposite direction or the same direction, the two guide rods 14 can provide support and guidance for the limiting plate 8. The limiting plate 8 moves along the guide rod 14, avoids tilting or shaking in the movement process, ensures that the limiting plate 8 can be accurately adjusted to the required position, so as to better limit the two sides of the paper, ensures that the paper will not deviate laterally in the conveying process, and further improves the positioning accuracy of the paper feeding.
[0025] The implementation principle of the positioning paper feeding mechanism of the carton forming machine is as follows: the driving motor 6 is preferably YE2132M-4 type, the servo motor 9 is preferably HBS57 type, and the electric telescopic rod 2 is preferably LX600 type. The driving motor 6, the servo motor 9 and the electric telescopic rod 2 are electrically connected with an external power source through switches. The paper feeding assembly is responsible for the conveying of the paper. The driving motor 9 at the side edge of the paper feeding table 1 is started through a switch, and the output end of the driving motor 9 drives the paper feeding roller 10 fixedly connected thereto to rotate. The friction between the paper feeding roller 10 and the paper body 13 wound outside the paper feeding roller 10 is utilized to realize the conveying of the paper. In the process of conveying the paper, the tension adjusting structure plays a role. The electric telescopic rod 2 on the surface of the paper feeding table 1 is started through a switch, and the extension of the output end of the electric telescopic rod 2 drives the tension adjusting block 3 connected thereto to move. The tension adjusting rod 4 fixedly connected to the outer side of the tension adjusting block 3 acts accordingly. If the paper is slack, the electric telescopic rod 2 is elongated to move the tension adjusting rod 4 upward, thereby increasing the tension of the paper. The auxiliary adjusting block 11 rotatably connected to the end of the tension adjusting rod 4 away from the electric telescopic rod 2 slides on the limiting rod 12 fixedly connected to the surface of the paper feeding table 1, thereby ensuring that the tension adjusting rod 4 moves stably and accurately. The paper body 13 passes through the gap between the upper arc surface of the tension adjusting rod 4 and the two guide rods 14 in sequence. The two guide rods 14 provide guidance and limiting for the paper conveying. Meanwhile, the two vertical plates 5 on the surface of the paper feeding table 1 support the entire width adjusting structure. The servo motor 6 on the outer side wall of one of the two vertical plates 5 is started through a switch, and drives the bidirectional screw rod 7 to rotate through a coupling. The threads on the two sides of the bidirectional screw rod 7 are oppositely arranged, have equal pitches and are arranged at an angle of 20 degrees. The self-locking condition of the threads needs to meet the following formula: self-locking condition = friction coefficient x tan(screw angle) ≥ 1. The two limiting plates 8 symmetrically connected to the outer threads of the bidirectional screw rod 7 move symmetrically towards or away from each other, thereby adjusting the conveying width of the paper. Since the limiting plates 8 penetrate through the two guide rods 14, the guide rods 14 provide support and guidance for the limiting plates 8, thereby ensuring that the limiting plates 8 accurately adjust the position and preventing the paper from deviating laterally, improving the positioning accuracy of the paper feeding and ensuring that the paper is stably and accurately conveyed to the subsequent processing link.
