Technical Field

[0001] This utility model relates to the field of chemical fiber paper tube technology, and in particular to a cylindrical chemical fiber paper tube cutting device. Background Technology

[0002] In the chemical fiber textile industry, tubular chemical fiber paper tubes serve as an important carrier for winding yarns, films, and other materials, and their processing quality directly affects subsequent production efficiency and product quality.

[0003] Traditional cylindrical chemical fiber paper tube cutting devices typically employ a fixed clamping structure, which can only accommodate paper tubes of a specific diameter. However, in actual production, paper tubes come in a variety of specifications, resulting in poor equipment versatility. When changing paper tubes of different sizes, it is necessary to frequently adjust or replace the clamps, which is not only cumbersome to operate but also reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of the diverse specifications of paper tubes in existing production, which leads to poor equipment versatility and the need for frequent adjustment or replacement of clamps when changing paper tubes of different sizes. This not only makes the operation cumbersome but also reduces production efficiency. Therefore, a tubular chemical fiber paper tube cutting device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tubular chemical fiber paper tube cutting device includes a base and a cutting machine. The top of the base is provided with a conveying groove, and a rectangular opening is provided in the conveying groove. Rollers that assist in the movement of the paper tube are provided in the rectangular opening. A pair of clamping mechanisms are provided inside the base, and a clamping box is provided on the base through the clamping mechanisms.

[0007] The clamping box is provided with a conveying structure, which is used to convey the paper tube after it has been clamped.

[0008] Preferably, the clamping mechanism includes a hydraulic cylinder, a connecting plate, and a limiting port. The hydraulic cylinder is fixedly disposed inside the base, the connecting plate is fixedly disposed at the bottom of the clamping box, and the limiting port is disposed at the top of the base.

[0009] Preferably, the connecting plate is fixedly mounted on the telescopic end of the hydraulic cylinder, the connecting plate is slidably connected to the limiting port, and the connecting plate is arranged in a cross shape.

[0010] Preferably, the conveying structure includes a first conveyor wheel, a second conveyor wheel, a third conveyor wheel, a transmission column, a first chain, a second chain, and a servo motor. The first conveyor wheel, the second conveyor wheel, and the third conveyor wheel are all rotatably mounted in the clamping box. The transmission column is fixedly mounted on the top of the first conveyor wheel, the second conveyor wheel, and the third conveyor wheel, respectively. The servo motor is fixedly mounted on the top of the clamping box.

[0011] Preferably, chain one is mounted on conveyor wheel one and conveyor wheel two, and chain two is mounted on conveyor wheel one and conveyor wheel three.

[0012] Preferably, the first chain is positioned above the second chain, and the output end of the servo motor is fixedly connected to the first conveyor wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When in use, this utility model can be adapted to paper tubes of different specifications by setting an adjustable clamping mechanism and multiple sets of conveying wheels. It eliminates the need for frequent clamp replacement or equipment adjustment, significantly enhancing the versatility of the device, reducing downtime caused by specification switching, reducing reliance on special clamps, extending the service life of the equipment, and reducing labor costs due to increased automation, thus comprehensively reducing production and maintenance costs.

[0015] 2. In use, this utility model can drive multiple sets of conveyor wheels in a unified manner through a servo motor, which simplifies the control process. Operators only need to adjust the hydraulic cylinder pressure to adapt to different paper tube sizes, which reduces the complexity of operation, reduces manual intervention, and greatly improves the efficiency of cutting operations.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 A tubular chemical fiber paper tube cutting device includes a base 1 and a cutting machine 2. The cutting machine 2 is existing technology in the field to which this technology belongs. It adopts laser cutting and its function is to cut the paper tube after it has been clamped and stabilized, so it will not be described in detail.

[0023] The top of the base 1 is provided with a conveying groove 3, and a rectangular opening 4 is provided in the conveying groove 3. A roller 5 for assisting the movement of the paper tube is provided in the rectangular opening 4. A pair of clamping mechanisms 6 are provided inside the base 1. The base 1 is provided with a clamping box 7 through the clamping mechanism 6. The clamping mechanism 6 includes a hydraulic cylinder 9, a connecting plate 10 and a limiting port 11. The hydraulic cylinder 9 is fixedly installed inside the base 1, the connecting plate 10 is fixedly installed at the bottom of the clamping box 7, and the limiting port 11 is located at the top of the base 1.

[0024] The clamping box 7 is provided with a conveying structure 8, which is used to convey the paper tube after it has been clamped. The conveying structure 8 includes a first conveyor wheel 12, a second conveyor wheel 13, a third conveyor wheel 14, a transmission column 15, a first chain 16, a second chain 17, and a servo motor 18. The first conveyor wheel 12, the second conveyor wheel 13, and the third conveyor wheel 14 are all rotatably mounted in the clamping box 7. The transmission column 15 is fixedly mounted on the top of the first conveyor wheel 12, the second conveyor wheel 13, and the third conveyor wheel 14, respectively. The servo motor 18 is fixedly mounted on the top of the clamping box 7.

[0025] It should be noted that the cutting machine 2, hydraulic cylinder 9, and servo motor 18 are existing technologies. The hydraulic cylinder 9 is used to push the connecting plate 10 to move, so that the clamping box 7 quickly approaches or moves away from the paper tube, achieving stable clamping of paper tubes of different diameters. In this utility model, multiple hydraulic cylinders 9 are supplied with oil through the same hydraulic pump station, and a flow divider valve or synchronization valve is used to control the oil circuit to ensure that the extension and retraction speed and stroke of each hydraulic cylinder 9 are consistent, avoiding one-sided pressure imbalance. The servo motor 18 is used to control the rotation of the conveyor wheel, which transports the clamped paper tube to the cutting machine 2 for cutting. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be elaborated. All of them can be powered and controlled to open and close by external equipment.

[0026] Furthermore, the connecting plate 10 is fixedly mounted on the telescopic end of the hydraulic cylinder 9, and the connecting plate 10 is slidably connected to the limiting port 11. The connecting plate 10 is arranged in a cross shape.

[0027] The sliding fit between the cross-shaped connecting plate 10 and the limiting port 11 further constrains the movement trajectory. Even if there are minor errors in the hydraulic system, the position can be forcibly corrected through the mechanical structure to ensure that the clamping force on both sides is balanced.

[0028] Furthermore, chain 16 is installed on conveyor wheel 12 and conveyor wheel 23, chain 2 17 is installed on conveyor wheel 12 and conveyor wheel 34, chain 16 is positioned above chain 2 17, and the output end of servo motor 18 is fixedly connected to conveyor wheel 12.

[0029] Among them, the first conveyor wheel 12, the second conveyor wheel 13 and the third conveyor wheel 14 rotate in the same direction. The second conveyor wheel 13 and the third conveyor wheel 14 are located at both ends of the clamping box 7, which makes the transport of the paper tube more stable and prevents the situation of being unable to move in the middle.

[0030] Working principle:

[0031] First, the paper tube to be cut is placed in the conveyor trough 3 by manual or automatic feeding mechanism, and is initially centered by the assistance of rollers 5. Servo motor 18 is started, driving conveyor wheel 12 to rotate, and conveyor wheel 13 and conveyor wheel 14 to rotate in the same direction through chain 16 and chain 2 17. The three sets of conveyor wheels (12, 13, 14) work together to smoothly convey the paper tube to the processing position of the cutting machine 2.

[0032] Then, when the paper tube reaches the predetermined cutting position, the hydraulic cylinder 9 is activated, pushing the cross-shaped connecting plate 10 to slide along the limiting port 11, driving the clamping box 7 to move towards the center of the paper tube. Since multiple hydraulic cylinders 9 use the same hydraulic pump station for oil supply and are equipped with a diverter valve or a synchronization valve, it ensures that the hydraulic cylinders 9 on both sides act synchronously, so that the clamping box 7 applies a balanced clamping force to the paper tube, avoiding skewing. The mechanical cooperation between the cross-shaped connecting plate 10 and the limiting port 11 further corrects the positional error, ensuring that the paper tube remains stable during the cutting process and does not shift or vibrate.

[0033] Finally, after the paper tube is firmly clamped, the cutting machine 2 starts and precisely cuts the paper tube according to the preset length. After the cutting is completed, the hydraulic cylinder 9 retracts, the clamping box 7 releases the paper tube, and the conveying structure 8 runs again to send out the cut paper tube. At the same time, a new paper tube enters the processing position to realize continuous production.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
