Description

Technical Field

[0001] This utility model relates to the field of paper tube making machine technology, and in particular to a paper pressing device for a paper tube making machine. Background Technology

[0002] Paper tubes, as an important packaging material, are widely used in industries such as papermaking, textiles, and printing. In the paper tube manufacturing process, the pressure roller is one of the key components of the paper tube making machine, and its performance directly affects the forming quality and production efficiency of the paper tube. In existing tube making machines, the paper tube is formed on a rotating mold, and a twisted belt wound around the mold presses the paper tube firmly, allowing for better forming.

[0003] A search revealed that Chinese patent application CN222022304U discloses a paper pressing device for a paper tube making machine. The device mainly uses a bidirectional threaded rod, a movable block, and a connecting rod to drive the paper pressing wheel to rise and fall, thereby adjusting the angle at which the paper pressing wheel and the roll are pressed together.

[0004] Compared with existing technologies in related fields, it can be seen that twisted belts are generally made of rubber. After continuous operation, the rubber belt will wear down and its tension will decrease, making it difficult to adjust the clamping force of the paper tube in a timely manner. This results in the paper layer of the paper tube not being firmly bonded, which affects the quality of the paper tube. Utility Model Content

[0005] The purpose of this invention is to provide a paper pressing device for a paper tube making machine in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A paper pressing device for a paper tube making machine includes a frame and a twisting belt. A power mechanism, a detection unit and a traction unit are fixedly installed on the frame. A forming roller is fixedly installed on the output shaft of the power mechanism. The twisting belt is wound around the forming roller and driven by the traction unit.

[0008] The traction unit includes a drive mechanism, a mounting frame, and a first spring. A base and an tilting assembly are fixedly mounted on the frame. The drive mechanism is rotatably mounted on the base and the tilting assembly. A rotating roller is fixedly mounted on the output shaft of the drive mechanism. A guide cavity and a hydraulic cavity are provided inside the rotating roller. Movable parts are slidably arranged on the rotating roller. A sealing piston mechanism and a material support assembly are fixedly mounted at both ends of the movable parts, respectively. The material support assembly is connected to a twisted belt. The first spring is sleeved on the movable parts. The first spring and the sealing piston mechanism are slidably connected in the hydraulic cavity. The mounting frame is fixedly mounted on the drive mechanism. A dynamic rotating connector and a cleaning unit are fixedly mounted on the mounting frame. The dynamic rotating connector is sealed and rotatably connected to the rotating roller. The dynamic rotating connector is connected to the hydraulic cavity through the guide cavity.

[0009] Furthermore, a hydraulic sensor is fixedly installed inside the dynamic rotating connector.

[0010] Furthermore, the support assembly includes a top plate, which is fixedly installed at the end of the movable part, and a ceramic plate is fixedly installed on the side of the top plate, which is connected to the twisted belt through friction engagement.

[0011] Furthermore, the tilting component includes a support and an electrically controlled telescopic mechanism. The support is fixedly installed on the lower surface of the drive mechanism and the frame. The electrically controlled telescopic mechanism is tilted, and its two ends are rotatably connected to the support.

[0012] Furthermore, an angle sensor is fixedly mounted on the lower surface of the drive mechanism.

[0013] Furthermore, the detection unit includes a support frame, a sliding frame, and a second spring. The support frame is fixedly installed on the machine frame and located on both sides of the forming roller. A placement frame is fixedly installed on the support frame, and a pressure sensor is fixedly installed on the placement frame. The sliding frame is slidably installed on the placement frame, and an elastic block is fixedly installed on the sliding frame. A roller is rotatably installed on the upper end of the sliding frame, and the roller is slidably connected to the twisted belt. The elastic block is located directly below the pressure sensor. The second spring is sleeved on the support leg of the placement frame, and the two ends of the second spring are respectively connected to the placement frame and the sliding frame.

[0014] Furthermore, the cleaning unit includes a nozzle and a dust hood, both of which are fixedly mounted on the mounting bracket. The nozzle and the twisted belt are at the same height, and the dust hood is located on both sides of the nozzle.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. When the detection unit detects deformation of the twisted belt, it adjusts the pressure in the guide cavity and hydraulic cavity through the dynamic rotating connector. This allows the moving part to drive the top plate and ceramic plate to effectively support the twisted belt, preventing changes in the force applied to the paper tube due to fatigue deformation of the twisted belt. It actively counteracts the slack of the twisted belt, allowing it to continuously apply force to the paper used to make the paper tube. The tilting component adjusts the force applied to the paper by the twisted belt, effectively improving the precise adjustment and compensation of the instantaneous pressure in the paper pressing area, ensuring the production quality and efficiency of the paper tube.

[0017] 2. The ceramic plate improves the wear resistance of the top plate, effectively reducing the wear of the twisted belt due to the wear of the top plate, extending its service life, and allowing the twisted belt to better press the paper used to make the paper tube. At the same time, the cleaning unit cleans the impurities adhering to the surface of the twisted belt, preventing impurities from being pressed into the surface of the paper tube and improving the surface quality of the paper tube.

Detailed Implementation

[0029] like Figures 1-8 As shown, a paper tube making machine pressing device includes a frame 1 and a twisting belt 7. A power mechanism 2, a detection unit, and a traction unit are fixedly installed on the frame 1. A forming roller 6 is fixedly installed on the output shaft of the power mechanism 2. The twisting belt 7 is wound around the forming roller 6. The twisting belt 7 is driven by the traction unit. The power mechanism 2, the forming roller 6, and the twisting belt 7 operate using existing technology. The power mechanism 2 drives the forming roller 6 to rotate, and the paper is wound and formed on the forming roller 6. During the paper tube forming process, the traction unit drives the twisting belt 7 to rotate, and the twisting belt 7 presses the paper tube, making the paper for making the paper tube fit more tightly. At the same time, the detection unit detects the force applied to the paper by the twisting belt 7, and the traction unit adjusts the force applied to the paper tube by the twisting belt 7 to ensure the quality of paper tube making.

[0030] like Figure 1 , Figure 2 , Figures 4-6As shown, the traction unit includes a drive mechanism 302, a mounting frame 314, and a first spring 307. A base 301 and an inclined assembly are fixedly mounted on the frame 1. The drive mechanism 302 is rotatably mounted on the base 301 and the inclined assembly. A rotating roller 303 is fixedly mounted on the output shaft of the drive mechanism 302. A guide cavity 304 and a hydraulic cavity 305 are provided inside the rotating roller 303. Movable parts 306 are slidably arranged on the rotating roller 303. A sealing piston mechanism and a material support assembly are fixedly mounted at both ends of the movable part 306, respectively. The material support assembly is connected to the twisted belt 7. The first spring 307 is sleeved on the movable part 306. The first spring 307 and the sealing piston mechanism slide... The dynamic connection is located within the hydraulic chamber 305. A mounting bracket 314 is fixedly mounted on the drive mechanism 302. A dynamic rotating connector 310 and a cleaning unit are fixedly mounted on the mounting bracket 314. The dynamic rotating connector 310 provides a sealed rotatable connection to the rotating roller 303. The dynamic rotating connector 310 is connected to the hydraulic chamber 305 via a guide chamber 304 and is also connected to an external hydraulic control device. The drive mechanism 302 and the dynamic rotating connector 310 operate using existing technology. The dynamic rotating connector 310 avoids affecting the rotation of the rotating roller 303. The drive mechanism 302 drives the rotating roller 303 to rotate. The rotating roller 303 is connected to the moving parts... 306 drives the material support assembly to rotate, which in turn drives the twisting belt 7 to rotate. The rotating twisting belt 7 applies force to the paper forming the paper tube on the forming roller 6, ensuring the quality of the paper tube. When the paper forming the paper tube changes, the tilting assembly adjusts the tilt state of the drive mechanism 302, thereby adjusting the instantaneous pressure of the twisting belt 7 on the paper. When the twisting belt 7 undergoes fatigue deformation, the detection unit detects a change in the force applied by the twisting belt 7 to the paper. The external hydraulic control device delivers hydraulic oil to the guide cavity 304 through the dynamic rotating connector 310, adjusting the hydraulic oil in the guide cavity 304 and the hydraulic cavity 305. The hydraulic oil in the hydraulic chamber 305 drives the movable part 306 to move through the sealed piston mechanism. The movable part 306 drives the material support assembly to move and compresses the first spring 307, so that the material support assembly supports the deformed twisted belt 7 and actively counteracts the slack of the twisted belt 7. This allows the twisted belt 7 to continuously apply force to the paper used to make paper tubes, avoiding changes in the force applied to the paper tubes due to fatigue deformation of the twisted belt 7, and ensuring the quality and efficiency of paper tube production. When the twisted belt 7 is replaced, if the hydraulic oil in the guide chamber 304 and the hydraulic chamber 305 decreases, the movable part 306 can be reset by the first spring 307.

[0031] like Figure 2 , Figure 6As shown, a hydraulic sensor is fixedly installed inside the dynamic rotating connector 310. The hydraulic sensor operates using existing technology. By installing the hydraulic sensor inside the dynamic rotating connector 310, the pressure of the hydraulic oil in the guide cavity 304 can be detected in real time, thereby better adjusting the pressure of the hydraulic oil in the guide cavity 304 and improving safety.

[0032] like Figure 5 , Figure 6 As shown, the support assembly includes a top plate 308, which is fixedly installed at the end of the movable part 306. A ceramic plate 309 is fixedly installed on the side of the top plate 308. The ceramic plate 309 is connected to the twisted belt 7 through friction engagement. The movable part 306 drives the ceramic plate 309 through the top plate 308 to support the twisted belt 7. The ceramic plate 309 improves the wear resistance of the top plate 308, effectively reducing the wear of the twisted belt 7 caused by the wear of the top plate 308 and extending its service life.

[0033] like Figure 6 , Figure 7 As shown, the tilting assembly includes a support 311 and an electrically controlled telescopic mechanism 312. The support 311 is fixedly installed on the lower surface of the drive mechanism 302 and the frame 1. The electrically controlled telescopic mechanism 312 is tilted, and its two ends are rotatably connected to the support 311. The electrically controlled telescopic mechanism 312 operates using existing technology. The electrically controlled telescopic mechanism 312 drives the drive mechanism 302 to move through the support 311, adjusting the tilt state of the drive mechanism 302. By adjusting the tilt of the drive mechanism 302, when the thickness of the paper used to make the paper tube changes, the force applied to the twisting belt 7 by the roller 303 can be adjusted, thereby adjusting the force applied to the paper by the twisting belt 7, effectively improving the precise adjustment and compensation of the instantaneous pressure of the twisting belt 7 on the paper pressing area, and ensuring the production quality and efficiency of the paper tube.

[0034] like Figure 7 As shown, a tilt sensor 313 is fixedly installed on the lower surface of the drive mechanism 302. The tilt sensor 313 operates using existing technology. The tilt angle of the drive mechanism 302 is detected by the tilt sensor 313. Based on the detection value of the tilt sensor 313, the tilt angle of the drive mechanism 302 can be accurately adjusted, effectively avoiding deviations during adjustment that could affect the production quality of the paper tube.

[0035] like Figure 3 , Figure 8As shown, the detection unit includes a support frame 401, a sliding frame 407, and a second spring 403. The support frame 401 is fixedly mounted on the frame 1 and located on both sides of the forming roller 6. A placement frame 402 is fixedly mounted on the support frame 401, and a pressure sensor 405 is fixedly mounted on the placement frame 402. The sliding frame 407 is slidably mounted on the placement frame 402, and an elastic block 404 is fixedly mounted on the sliding frame 407. A roller 406 is rotatably mounted on the upper end of the sliding frame 407, and the roller 406 is slidably connected to the twisted belt 7. The elastic block 404 is located directly below the pressure sensor 405. The second spring 403 is sleeved on the support leg of the placement frame 402, and the two ends of the second spring 403 are respectively connected to the placement frame 402 and the sliding frame 407. The pressure sensor 405 operates using existing technology, and the roller 406 prevents the movement of the twisted belt 7 from being affected during the detection process. During the paper tube production process, the twisted belt 7 applies a force to the roller 406, causing the roller 406 to rotate along with the twisted belt 7. Simultaneously, the second spring 403 applies a force to the roller 406 through the sliding frame 407, ensuring that the roller 406 remains in contact with the twisted belt 7. At the same time, the roller 406, through the sliding frame 407, drives the elastic block 404, which applies a force to the pressure sensor 405. The pressure sensor 405 then detects the tension of the twisted belt 7, facilitating adjustment and control of the force applied to the paper tube by the twisted belt 7. The elastic block 404 continuously applies a force to the pressure sensor 405, allowing for continuous monitoring of the tension value of the twisted belt 7. When the tension of the twisted belt 7 changes, the detection value of the pressure sensor 405 changes, enabling timely adjustments to ensure the quality of paper tube production.

[0036] like Figure 2 , Figure 5 , Figure 6 As shown, the cleaning unit includes a nozzle 501 and a dust suction hood 502. Both the nozzle 501 and the dust suction hood 502 are fixedly mounted on the mounting bracket 314. The nozzle 501 is at the same height as the twisted belt 7, and the dust suction hood 502 is located on both sides of the nozzle 501. The nozzle 501 is connected to an external air supply device, and the dust suction hood 502 is connected to an external dust suction device. The external air supply device sprays air onto the surface of the twisted belt 7 through the nozzle 501, thereby cleaning the impurities adhering to the surface of the twisted belt 7, improving the cleanliness of the surface of the twisted belt 7, preventing impurities from being pressed into the surface of the paper tube, and improving the quality of the paper tube surface. At the same time, the external dust suction device absorbs impurities through the dust suction hood 502, reducing environmental pollution.

[0037] Working principle: such as Figures 1-6 , Figure 8As shown, the forming roller 6 is driven to rotate by the power mechanism 2, and the paper is wound and formed on the forming roller 6. During the paper tube forming process, the rotating roller 303 is driven to rotate by the drive mechanism 302. The rotating roller 303 drives the top plate 308 and the ceramic plate 309 to rotate through the movable part 306. The top plate 308 and the ceramic plate 309 drive the twisting belt 7 to rotate. The rotating twisting belt 7 applies force to the paper forming the paper tube on the forming roller 6 to ensure the quality of the paper tube.

[0038] like Figure 3 , Figure 8 As shown, the second spring 403 applies a force to the roller 406 through the sliding frame 407, so that the roller 406 always fits against the twisted belt 7. The roller 406 drives the elastic block 404 through the sliding frame 407, which applies a force to the pressure sensor 405. The tension of the twisted belt 7 is detected by the pressure sensor 405. The tension of the twisted belt 7 is judged based on the pressure detected by the pressure sensor 405.

[0039] like Figure 6 , Figure 7 As shown, when the thickness of the paper used to make the paper tube changes, the electronically controlled telescopic mechanism 312 drives the drive mechanism 302 to move through the support 311, adjusts the tilt state of the drive mechanism 302, and detects the tilt angle of the drive mechanism 302 through the tilt sensor 313, thereby adjusting the force applied to the paper by the twisted belt 7, effectively improving the accuracy of the adjustment and compensation of the instantaneous pressure of the twisted belt 7 on the paper pressing area.

[0040] like Figure 1 , Figure 2 , Figures 4-6 As shown, when the twisted belt 7 undergoes fatigue deformation, according to the pressure change detected by the pressure sensor 405, the external hydraulic control device delivers hydraulic oil to the guide cavity 304 through the dynamic rotating connector 310, adjusts the amount of hydraulic oil in the guide cavity 304 and the hydraulic cavity 305, and the hydraulic oil in the hydraulic cavity 305 drives the moving part 306 to move through the sealing piston mechanism. The moving part 306 drives the top plate 308 and the ceramic plate 309 to move, so that the top plate 308 and the ceramic plate 309 support the deformed twisted belt 7, actively counteract the slack of the twisted belt 7, so that the twisted belt 7 can continuously apply force to the paper used to make paper tubes to ensure the quality and efficiency of paper tube making;

[0041] like Figure 2 , Figure 5 , Figure 6 As shown, during the paper tube manufacturing process, the external air supply device sprays air onto the surface of the twisted belt 7 through the nozzle 501 to clean the impurities adhering to the surface of the twisted belt 7. At the same time, the external dust collection device absorbs the impurities through the dust collection hood 502 to ensure the quality of paper tube production.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
