Description

Technical Field

[0001] The utility model relates to the technical field of wrapping machines, in particular to a disc changing device applied to wrapping machines. Background Art

[0002] The reel support of a wrapping machine is a device used to support and secure the reel, ensuring smooth and even conveyance of the tape during the unwinding process. In the prior art, the reel support of a wrapping machine generally uses ratchet locking technology to manually replace the reel. While this technology is mature and reliable, it suffers from significant efficiency issues in practical applications. Each replacement of the reel requires manual operation, which is time-consuming, typically taking more than three minutes. In a high-intensity, continuous production environment, frequent reel replacement not only significantly reduces production efficiency but also increases the labor intensity of the operator. Furthermore, human errors and improper operation during the manual replacement process may also result in loose installation of the reel, impacting production quality.

[0003] More seriously, this manual replacement method presents significant safety risks. Over extended use, the threads of the screws gradually wear out. If not detected and addressed promptly, they can suddenly loosen during production, causing the reel to fly out. This situation can not only damage the equipment but also cause serious injury to the operator, leading to major safety accidents. Therefore, existing reel replacement methods urgently need to be improved in terms of efficiency and safety to meet the high-efficiency and safety requirements of modern industrial production.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Figure 1 The figure shows a schematic structural diagram of a disc changing device applied to a wrapping machine provided by an exemplary embodiment of the present invention. Figure 2 Shown Figure 1 A local enlarged schematic diagram, Figure 3 Shown Figure 1 The partially enlarged schematic diagram at point B shows that the disk changing device 1 applied to the wrapping machine is installed below the tape reel bracket 3 of the wrapping machine 2. The disk changing device 1 applied to the wrapping machine specifically includes: a multi-station clamping arm 11, a driving mechanism 14, and a locking tongue mechanism 15. The multi-station clamping arm 11 has multiple clamping station ends 12, and the clamping station end 12 can clamp or release the plug-in end 131 of the tape reel 13; the driving mechanism 14 is used to drive the multi-station clamping arm 11 to rise and fall and rotate; the locking tongue mechanism 15 is installed on the docking end 31 of the tape reel bracket 3, and is used for quickly docking the plug-in end 131 of the tape reel 13; wherein, the plug-in end 131 of the tape reel 13 includes a clamping portion 1311 adapted to the clamping station end 12, and a locking tongue portion 1312 adapted to the locking tongue mechanism 15.

[0035] In one example, the multi-station clamping arm 11 has two clamping station ends 12. In another example, the multi-station clamping arm 11 has three clamping station ends 12. In another example, the multi-station clamping arm 11 has four clamping station ends 12. This application does not limit the number of clamping station ends 12, and it can be flexibly adjusted according to actual working conditions.

[0036] In the embodiment of the present application, the clamping station end 12 clamps or releases the plug-in end 131 of the tape reel 13 through its built-in clamping cylinder.

[0037] Understandable, see Figure 4The multi-station clamping arm 11, the driving mechanism 14, and the locking tongue mechanism 15 are all electrically connected to the electrical control cabinet of the wrapping machine 2 to cooperate with the various components of the wrapping machine; specifically, the electrical control cabinet of the wrapping machine 2 realizes the coordinated work control of various components through the built-in programmable logic controller PLC.

[0038] Further, see Figures 1 to 3 The lock tongue portion 1312 includes a frustum-shaped locking portion 13121 and a step-shaped limiting portion 13122 . The locking portion 13121 is adapted to the lock tongue mechanism 15 and is limited by the limiting portion 13122 .

[0039] In the embodiment of the present application, the diameter of the locking portion 13121 at one end close to the limiting portion 13122 is smaller than the diameter of the locking portion 13121 at one end away from the limiting portion 13122 .

[0040] Specifically, see Figures 1 to 3 The lock tongue mechanism 15 includes a lock tongue cylinder 151 installed on the docking end 31, and a spring lock tongue 152 connected to the power output end of the lock tongue cylinder 151. The shape of the locking end of the spring lock tongue 152 is adapted to the frustum-shaped locking portion 13121.

[0041] In the embodiment of the present application, by providing a frustum-shaped locking portion 13121 and a step-shaped limiting portion 13122, the tape reel 13 is firmly clamped in cooperation with the spring lock tongue 152, and the tape reel 13 is prevented from sliding.

[0042] For further information, see Figures 1 to 3 The driving mechanism 14 includes a rotating motor 141, a rotating base 142 connected to the power output end of the rotating motor 141, a lifting motor 143 installed on the rotating base 142, and a telescopic rod 144 connected to the power output end of the lifting motor 143; wherein the center part of the multi-station clamping arm 11 is connected to the telescopic rod 144.

[0043] Next, the working principle of the disc changing device applied to the wrapping machine involved in the embodiment of the present invention is described.

[0044] When the tape reel bracket of the wrapping machine needs to be loaded, the clamping station end holding the tape reel is rotated to the bottom of the docking end of the tape reel bracket. The rotation process is specifically driven by the rotating motor to drive the rotating seat to rotate, and then drive all the components on the rotating seat to rotate, so as to realize the rotation of the clamping station end; then the lifting motor drives the telescopic rod to rise, so that the plug-in end of the tape reel is inserted into the docking end of the tape reel bracket, and after the lock tongue cylinder is started, the spring lock tongue is used to lock the lock tongue part; the clamping station end releases the clamping part of the tape reel, and the lifting motor drives the telescopic rod to descend, and the loading is completed;

[0045] When the tape reel bracket of the wrapping machine needs to unload the reel, the clamping station end in the empty state is rotated to the bottom of the docking end of the tape reel bracket. The rotation process is specifically driven by the rotating motor to drive the rotating seat to rotate and then drive all the components on the rotating seat to rotate, so as to realize the rotation of the clamping station end; then the lifting motor drives the telescopic rod to rise until the clamping station end can clamp to the clamping part of the tape reel, and the spring lock tongue of the lock tongue cylinder retracts to cancel the locking of the lock tongue part; the lifting motor drives the telescopic rod to descend, and the unloading of the reel is completed.

[0046] In summary, the reel-changing device for a wrapping machine is arranged below the reel support of the wrapping machine. The device includes a multi-station clamping arm, a drive mechanism, and a locking tongue mechanism. The multi-station clamping arm has multiple clamping station ends, which can clamp or release the plug-in end of the reel. The drive mechanism is used to drive the multi-station clamping arm to rise, fall, and rotate. The locking tongue mechanism is installed on the docking end of the reel support and is used to quickly dock with the plug-in end of the reel. The plug-in end of the reel includes a clamping portion adapted to the clamping station end and a locking tongue portion adapted to the locking tongue mechanism. In this case, a reel-changing device with high efficiency and strong safety can be provided to meet the requirements of modern industrial production for efficiency and safety.
