[0002] In the production process of cotton swab products, neatly and efficiently packing cotton swabs into packaging bags has always been a challenging link. Traditional cotton swab bagging methods often rely on manual operation or simple automated equipment, but these methods often seem inadequate when faced with large-scale, high-efficiency production needs. Although some automated bagging equipment currently available on the market has improved bagging efficiency to a certain extent, they often have problems such as poor adaptability and high maintenance costs. For example, these devices usually need to be customized according to specific cotton swab specifications and packaging bag sizes. Once the specifications of the cotton swabs or packaging bags change, the equipment needs to be readjusted or replaced, which increases production costs and complexity. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0032] Please also read Figures 1 to 3 Now, a rotary feeding assembly structure for a bag-feeding packaging machine provided in an embodiment of the present application is described. The rotary feeding assembly structure for a bag-feeding packaging machine includes a base 101, a rotating arm 102 and a clamping assembly. Among them:

[0033] The rotating arm 102 is rotatably mounted on the base 101. The clamping assembly includes a clamping cylinder 103 and an outer clamping plate 104 mounted on the rotating arm 102, and also includes an inner clamping plate 105 connected to the power end of the clamping cylinder 103. The inner clamping plate 105 cooperates with the outer clamping plate 104 to enclose a cylindrical clamping space with two ends open. The outer edge portion of the inner clamping plate 105 overlaps with the corresponding inner edge portion of the outer clamping plate 104 and is slidably connected. The relative sliding direction of the inner clamping plate 105 and the outer clamping plate 104 is parallel to the output direction of the clamping cylinder 103.

[0034] According to the above structure provided in the present embodiment, it is usually installed on the workbench of the bag-feeding packaging machine at the loading station through the support column 118, and is connected with the output end of the cotton swab making equipment. In the rotary feeding assembly structure for the bag-feeding packaging machine provided in the present embodiment, the clamping assembly is installed on the rotatable rotating arm 102. The rotation of the rotating arm 102 can enable the clamping assembly to realize fast loading and unloading, thereby meeting the high-speed production requirements of modern equipment. That is, when the cylindrical clamping space with openings at both ends formed by the inner clamping plate 105 and the outer clamping plate 104 rotates to a horizontal state, the clamping cylinder 103 retracts to make the inner clamping plate 105 move away from the outer clamping plate 104 (the inner clamping plate 105 and the outer clamping plate 104 are not separated from the matching position) to increase the cylindrical clamping space. At this time, the feeding port of the cylindrical clamping space is aligned with the cotton swab making equipment. The output end of the equipment is aligned to receive the cotton swab output from the output end of the cotton swab making equipment. In order to prevent the cotton swab from slipping out from the outlet end and to ensure that the cotton swab is neat in the cylindrical clamping space, the baffle plate 115 rises to block the outlet end of the cylindrical clamping space (see below). Then, the clamping cylinder 103 extends to make the inner clamping plate 105 close to the outer clamping plate 104, and clamp the cotton swab in the cylindrical clamping space. The baffle plate 115 descends and resets to leave the movement trajectory area when the cylindrical clamping space rotates. The rotating arm 102 rotates to make the cylindrical clamping space turn to a vertical state. At this time, the outlet end of the cylindrical clamping space is located above the opened packaging bag clamped on the bag-feeding packaging machine. Then, the clamping cylinder 103 retracts to make the inner clamping plate 105 loosen away from the cotton swab relative to the outer clamping plate 104 and fall into the packaging bag, completing the feeding action, and so on. In addition, the inner clamping plate 105 connected to the power end of the clamping cylinder 103 cooperates with the outer clamping plate 104 to form a cylindrical clamping space. Since the inner clamping plate 105 can slide relative to the outer clamping plate 104 connected to the rotating arm 102 under the drive of the clamping cylinder 103, when the inner clamping plate 105 slides relative to the outer clamping plate 104, the radial size and volume of the cylindrical clamping space can be adjusted, which is conducive to making the cylindrical clamping space more convenient to adapt to cotton swab packaging specifications of different sizes, and its good adaptability is far superior to the feeding components in the current prior art.

[0035] In another embodiment of the present application, please refer to Figures 1 to 3, the rotary feeding assembly structure for the bag-feeding packaging machine also includes a driving mechanism for driving the rotating arm 102. In this embodiment, the driving mechanism includes a flip cylinder 106 connected to the base 101, a rack 107 connected to the output end of the flip cylinder 106, and a gear 108 that forms a transmission pair with the rack 107, and the rotating arm 102 is connected to the gear 108. According to the above structure provided in this embodiment, the piston rod of the flip cylinder 106 can drive the rack 107 to move when it is extended and retracted, thereby rotating the gear 108 engaged with the rack 107. Since the rotating arm 102 is connected to the gear 108, the rotating arm 102 can also rotate during the rotation of the gear 108, so as to adapt to different target stations and complete the feeding and adding operations. This embodiment significantly improves the rotation stability of the rotating arm 102 by adopting the above structure.

[0036] In another embodiment of the present application, please refer to Figures 1 to 3 The driving mechanism further includes a rotating support 109 connected to the base 101 and used to support the gear 108. The gear 108 is sandwiched between the rotating support 109 and the base 101, and the rotation center axis of the gear 108 passes through the rotating support 109 and is connected to the rotating arm 102. According to the above structure provided in this embodiment, since the gear 108 is clamped and supported between the rotating support 109 and the base 101, a more stable rotation stability can be achieved, which is conducive to further improving the material taking stability of the rotary feeding assembly structure for the bag packaging machine in this embodiment.

[0037] In another embodiment of the present application, please refer to Figures 1 to 3 The driving mechanism further includes a guide block 110 connected to the base 101, and the rack 107 has a guide portion 111 slidably connected to the guide block 110. According to the above structure provided in this embodiment, when the rack 107 is driven by the flip cylinder 106 and moves, the guide block 110 can be slidably connected to the guide portion 111, thereby providing a moving guide for the rack 107, which is beneficial to further improve the rotation stability of the rotating arm 102, and further improve the material picking stability of the rotary feeding assembly structure for the bag-type packaging machine in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 3The end of the rack 107 is connected with a linkage plate 112, and the rack 107 is connected to the power end of the flip cylinder 106 through the linkage plate 112. According to the above structure provided in this embodiment, the power end of the flip cylinder 106 and the end of the rack 107 are connected through the linkage plate 112, so that a larger sliding contact area can be provided between the rack 107 and the guide block 110 without affecting the rack 107 driven by the flip cylinder 106, which is conducive to further improving the rotation stability of the rotating arm 102 and further improving the material picking stability of the rotary feeding assembly structure for the bag packaging machine in this embodiment.

[0039] In another embodiment of the present application, please refer to Figures 1 to 3 The rotary feeding assembly structure for the bag-feeding packaging machine also includes a fixed bracket 113, a blocking cylinder 114 connected to the bracket 113, and a blocking plate 115 connected to the power end of the blocking cylinder 114. The moving path of the blocking plate 115 is perpendicular to the rotation path of the horizontal cylindrical clamping space and is used to close the discharge end opening of the cylindrical clamping space. According to the above structure provided in this embodiment, focus on Figure 2 When the cylindrical clamping space rotates to a horizontal position with the rotating arm 102, an opening on the left side of the cylindrical clamping space is used for feeding, that is, the side opening is a feeding port for receiving cotton swabs output by the cotton swab making equipment. The baffle plate 115 can rise under the action of the baffle cylinder 114 to close the other end opening of the cylindrical clamping space, that is, to block the outlet end, which can not only achieve the technical effect of fast loading, but also achieve the technical effect of fast sorting of materials during the loading process, which is conducive to further improving the adaptability of the rotary feeding component structure for the bag packaging machine in this embodiment.

[0040] As can be understood from the above, the base 101 and the bracket 113 can be respectively installed on the working table of the bag-feeding packaging machine through the support columns 118, and the adjustment and adaptation of the specific installation positions can adopt the existing technology of installation and adjustment of various components of the bag-feeding packaging machine.

[0041] In another embodiment of the present application, please refer to Figures 1 to 3 The rotary feeding assembly structure for the bag-feeding packaging machine further includes a positioning plate 116 connected to the base 101, at least two positioning plates 116 are arranged at intervals on the rotation path of the rotating arm 102, and the rotating arm 102 extends into the interval formed between adjacent positioning plates 116 and is used to rotate within the range limited by the two positioning plates 116. According to the above structure provided in this embodiment, the positioning plates 116 arranged on the rotation path of the rotating arm 102 can limit the rotation range of the rotating arm 102, which is conducive to faster operation of the rotating arm 102 and improves the position accuracy of the rotary feeding assembly structure for the bag-feeding packaging machine provided in this embodiment, thereby ensuring the feeding efficiency.

[0042] In another embodiment of the present application, please refer to Figures 1 to 3 A buffer seat 117 made of elastic material is disposed on the side of the positioning plate 116 facing the rotating arm 102. According to the above structure provided in this embodiment, by disposing the buffer seat 117 on the positioning plate 116, it is beneficial to reduce the impact force on the rotating arm 102 during the process of the positioning plate 116 limiting the rotating arm 102, which is beneficial to further improve the material taking stability of the rotary feeding assembly structure for the bag-feeding packaging machine in this embodiment.
