Description

Technical Field

[0001] This utility model relates to the field of fabric winding technology, and in particular to an automatic paper tube tightening and loosening device. Background Technology

[0002] In existing fabric winding equipment, an expansion shaft is generally used as the winding shaft. First, a paper roll is fitted over the expansion shaft, and then the shaft is inflated to limit the paper roll's circumferential position. The expansion shaft is then connected to a drive motor to wind the fabric onto the paper roll surface. While this expansion shaft allows for quick connection and separation from the paper roll, to avoid interference during rotation, the air inlet of the existing expansion shaft is typically located on its circumferential sidewall. This requires manual inflation and deflation using a handheld air gun and other tools, making the operation inconvenient. Utility Model Content

[0038] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0039] Please refer to Figures 1-4 An automatic paper tube tightening and loosening device includes a drive mechanism 1, an expansion shaft 2, and an air inlet assembly 3. The output end of the drive mechanism 1 is coaxially arranged and drivenly connected to the expansion shaft 2. One end of the air inlet assembly 3 passes through the output end of the drive mechanism 1 and communicates with the expansion shaft 2, and the air inlet assembly 3 and the expansion shaft 2 are rotatably arranged relative to each other. The other end of the air inlet assembly 3 is located outside the drive mechanism 1. The air inlet assembly 3 and the output end of the drive mechanism 1 are rotatably arranged relative to each other.

[0040] It is understood that this utility model adopts the method of setting an air intake component 3 at the output end of the drive mechanism 1, and making the air intake component 3 pass through the output end of the drive mechanism 1 and connect with the expansion shaft 2. This can realize the automatic inflation and deflation of the expansion shaft 2, and avoid interference during the rotation of the expansion shaft 2. Compared with the prior art, the degree of automation is higher and the inflation and deflation efficiency of the expansion shaft 2 is greatly improved.

[0041] In some embodiments, the drive mechanism 1 includes a housing 11, a drive motor 12, and a transmission assembly 13. The housing 11 covers the transmission assembly 13. The drive motor 12 passes through the housing 11 and is connected to the input end of the transmission assembly 13. The output end of the transmission assembly 13 is coaxially arranged with and connected to the expansion shaft 2. The air intake assembly 3 passes through the output end of the transmission assembly 13 and communicates with the expansion shaft 2. Preferably, the drive motor 12 is a servo motor. The air intake assembly 3 communicating with the expansion shaft 2 through the output end of the transmission assembly 13 ensures both the normal rotation of the expansion shaft 2 and the normal operation of the inflation and deflation functions of the expansion shaft 2, thereby achieving automated control.

[0042] In some embodiments, the transmission assembly 13 includes a drive pulley 131, a belt 132, and a driven pulley 133; the drive pulley 131 is driven by the drive motor 12; the driven pulley 133 is driven by the drive pulley 131 via the belt 132; the expansion shaft 2 is coaxially arranged and driven by the driven pulley 133, and the intake assembly 3 passes through the axis of the driven pulley 133 and communicates with the expansion shaft 2. Due to the belt drive structure, the intake assembly 3 can pass through the transmission assembly 13 and communicate with the expansion shaft 2, avoiding interference and ensuring the coaxiality of the intake assembly 3 and the expansion shaft 2, thus preventing the intake assembly 3 from being forced to rotate and damaged during the rotation of the expansion shaft 2.

[0043] In some embodiments, a coupling 4 is provided between the expansion shaft 2 and the driven wheel 133, and the intake assembly 3 passes through the coupling 4 and communicates with the expansion shaft 2. Specifically, the intake assembly 3 and the coupling 4 are rotatably arranged to avoid the intake assembly 3 from rotating due to the rotation of the coupling 4.

[0044] In some embodiments, the system further includes a bracket 5; a drive motor 12 is connected to the bracket 5; and a coupling 4 is embedded within the bracket 5. The bracket 5 is provided to support the coupling 4, ensuring the stability of the coupling 4, and thus ensuring the structural stability of the driven wheel 133 and the coupling 4.

[0045] In some embodiments, an air pipe 6 is also included; the air intake assembly 3 is connected to the inflation device via the air pipe 6. Specifically, by controlling the inflation and deflation state of the inflation device, the inflation and deflation state of the expansion shaft 2 can be directly controlled, thereby improving the level of automation.

[0046] In some embodiments, the air intake assembly 3 is either right-angled or straight. When the air intake assembly 3 is right-angled, the air pipe 6 can avoid bending as much as possible and is distributed along the surface of the housing 11, reducing the space occupied. Preferably, the air intake assembly 3 is right-angled.

[0047] In some embodiments, the air intake assembly 3 includes an air nozzle 31 and an extension tube 32; the air nozzle 31 is connected to the expansion shaft 2 via the extension tube 32, and the air nozzle 31 is disposed outside the drive mechanism 1. Specifically, one end of the extension tube 32 is rotatably connected to the air nozzle 31 or to the expansion shaft 2, and a sealing ring is provided between the extension tube 32 and the object undergoing relative rotation to ensure the effectiveness of inflation and deflation. Preferably, the extension tube 32 is rotatably connected to the air nozzle 31, while the air nozzle 31 is detachably connected to the fixed end of the coupling 4, so that the air nozzle 31 remains relatively stationary with respect to the coupling 4 and the air tube 6 during the rotation of the expansion shaft 2.

[0048] In some embodiments, the side of the housing 11 away from the drive motor 12 is open.

[0049] In some embodiments, a through hole 14 is provided on the side of the housing 11 away from the expansion shaft 2, through which the air supply pipe 6 passes; the air pipe 6 passes through the through hole and communicates with the air intake assembly 3, and the through hole is not coaxial with the expansion shaft 2. The through hole provides space for the air pipe 6 to communicate with the air intake assembly 3, and also serves to limit the movement of the air pipe 6.

[0051] An automatic paper tube tightening and loosening device includes a drive mechanism 1, an expansion shaft 2, and an air inlet assembly 3.

[0054] In this embodiment, a coupling 4 is provided between the expansion shaft 2 and the driven wheel 133, and the air intake assembly 3 passes through the coupling 4 and communicates with the expansion shaft 2.

[0060] The working principle of this utility model is as follows:

[0061] The inflation and deflation status of the expansion shaft 2 are controlled by the inflation device. Specifically, when the expansion shaft 2 needs to be separated from the wound fabric roll, the inflation device controls the expansion shaft 2 to deflate, so that the expansion shaft 2 is separated from the paper tube of the fabric roll.

[0062] When the expansion shaft 2 is replaced with a new paper tube and is about to enter the winding state, the inflation device controls the expansion shaft 2 to inflate, so that the expansion shaft 2 is tightly connected to the paper tube.
