[0030] The utility model is further described in detail below with reference to the drawings. It is necessary to point out that the following embodiments are only used for further illustrating the utility model and cannot be understood as limiting the protection scope of the utility model. Those skilled in the art can make some non-essential improvements and adjustments to the utility model according to the above application content.

[0031] Embodiment:

[0032] As shown in Figures 1 to 3 The utility model provides a strapping machine feeding structure, including setting up on the strapping machine frame 101, one side of frame 101 is provided with mounting column 105, rotatable sleeve is provided with mounting sleeve 201 on mounting column 105, frame 101 still is provided with the drive mechanism of drive mounting sleeve 201 rotation, sleeve is provided with material belt wheel 301 on mounting sleeve 201, and drive mechanism includes the first gear 102 of rotatable setting on frame 101 through motor drive and the second gear 202 of setting on mounting sleeve 201, and the first gear 102 is engaged with second gear 202.

[0033] The feeding structure can drive the mounting sleeve 201 to rotate by controlling the motor to drive the first gear 102 to rotate when in use. The material belt wheel 301 above the mounting sleeve 201 can be driven to rotate when the mounting sleeve 201 rotates, so as to supply the strapping machine with materials.

[0034] As shown in Figures 1 to 3 In the embodiment, the middle section of the operating rod 108 is hinged to the mounting column 105, and the frame 101 is provided with a locking mechanism that can selectively lock the position of the operating rod 108. The locking mechanism includes a clamping frame 103 provided on the frame 101. The operating rod 108 can be clamped in the clamping frame 103 after being rotated. The clamping frame 103 is also provided with a sliding bolt 104, and the operating rod 108 abuts the inner side of the bolt 104.

[0035] The bolt 104 can be pulled out to disengage the operating rod 108, thereby releasing the locking of the operating rod 108. After the operating rod 108 is rotated to the same axis as the mounting column 105, the material belt wheel 301 can be replaced. In some embodiments, one side of the bolt 104 can be wedge-shaped. By rotating the operating rod 108, the wedge-shaped surface of the bolt 104 can be pushed to automatically open, further increasing the efficiency of replacing the material belt wheel 301.

[0036] As shown in Figures 2 to 5As shown, in this embodiment, multiple sets of locking frames 203 are circumferentially hinged within the mounting sleeve 201. The operating lever 108 is connected to the locking frames 203 via a drive mechanism, which converts the swinging motion of the locking frames 203 into the opening and closing of the locking frames 203. The drive mechanism includes a mounting plate 106 slidably mounted on the mounting column 105. The inner sides of the multiple sets of locking frames 203 are inclined surfaces, and the mounting plate 106 abuts against the inclined inner surfaces of the locking frames 203. One end of the linkage rod 107 is hinged to the mounting plate 106, and the other end is hinged to the end of the operating lever 108. An elastic element 205 is provided between the mounting sleeve 201 and the locking frames 203. Multiple sets of slots 302 are circumferentially formed on the inner side of the pulley 301, and a locking block 204 is provided on the outer side of the locking frame 203, which is engaged within the slots 302.

[0037] When the operating lever 108 is rotated so that it is on the same axis as the mounting column 105, the mounting plate 106 is pushed to move along the side close to the frame 101 via the linkage lever 107. The mounting plate 106 moves along the inclined surface of the locking frame 203. The locking frame 203 is pushed by the elastic element 205 and rotates along its hinge point with the mounting sleeve 201 so that multiple sets of locking frames 203 can be closed, thus releasing the fixation of the material pulley 301. After replacing the new material pulley 301, the operating lever 108 is reversed, which can drive the mounting plate 106 to reset, thereby pushing multiple sets of locking frames 203 to open and fix the position of the material pulley 301. After the locking bracket 203 is opened, its outer side is flush with the outer circular surface of the mounting sleeve 201 to provide stable support for the material pulley 301. The arrangement of the locking block 204 and the locking groove 302 enables the mounting sleeve 201 and multiple sets of locking brackets 203 to stably control the rotation of the material pulley 301 for material feeding during rotation, thus preventing the material pulley 301 from slipping on the mounting sleeve 201.

[0038] like Figure 3 As shown, in some embodiments, the outer circular surface of the mounting plate 106 is provided with a bearing, which abuts against the inner inclined surface of the multiple sets of locking frames 203. The bearing can reduce the friction between the multiple sets of locking frames 203 and the mounting plate 106 during rotation, thereby improving the service life of the feeding structure.

[0039] The specific usage and beneficial effects of this utility model are as follows:

[0040] The feeding structure, in use, firstly releases the locking of the operating rod 108 by the locking mechanism, and rotates the operating rod 108 to the same axis as the mounting column 105, controls the plurality of locking frames 203 to fold in the process of rotation of the operating rod 108 through the driving mechanism, then passes the material belt wheel 301 through the operating rod 108 and sets the material belt wheel 301 on the mounting sleeve 201, finally reverses the operating rod 108 and locks the position of the operating rod 108 through the locking mechanism, controls the plurality of locking frames 203 to open in the process of rotation of the operating rod 108 through the driving mechanism, so as to fix the position of the material belt wheel 301 and the locking frames 203 and the mounting sleeve 201, thereby quickly completing the installation and position locking of the material belt wheel 301, and the mounting sleeve 201 can be controlled to rotate through the driving mechanism to drive the material belt wheel 301 to rotate, the material belt wheel 301 is installed through the feeding structure, compared with the traditional bolt installation mode, the installation is more convenient and fast, and the material belt wheel 301 is not easy to deviate or fall off due to loosening of the bolt, and the practicability is higher.
