Description

Technical Field

[0001] The invention relates to a rotating suction head mechanism. Background Art

[0002] The wrapping machine is a device designed and manufactured to meet the packaging requirements of containerized storage, transportation and mechanized loading and unloading operations of goods. It is widely used in the containerization cost of products such as foreign trade exports, food and beverages, canning, paperboard, dyes, plastic chemicals, glass ceramics, and electromechanical castings. For example, a Chinese patent for a fully automatic cardboard sleeve wrapping machine (patent number CN211167583U) has a technical solution including a cup feeding frame, a material clamping and feeding mechanism, a corner wrapping mechanism, a feeding conveyor belt, a cardboard conveying mechanism, a set of clamping machine seats, a plurality of feeding seats, a sliding lateral conduction component, a lifting drive mechanism, a paper receiving seat, a material receiving gripper and a material grabbing suction cup (103). The method for transferring the cardboard in the wrapping machine is:

[0003] During the circumferential rotation of the paper receiving seat, the cardboard in the stop plate is sucked out of the feeding trough by the suction cup. When the suction cup with the cardboard rotates to be parallel to the feeding conveyor belt, the suction cup is deflated to discharge the cardboard.

[0066] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0067] Embodiment 1:

[0068] like Figures 1 to 4 As shown, an embodiment of the present application provides a rotating suction head mechanism, including a frame 6, a rotating base 101, a plurality of support arms 102 and a plurality of material grabbing suction cups 103, and also includes a driving device 2, which is used to drive the rotating base 101 to rotate circumferentially; a linkage device 3, which includes a plurality of linkage shafts 301, which is used to make each support arm 102 rotate circumferentially around the linkage shaft 301 while rotating with the rotating base 101, and each material grabbing suction cup 103 is respectively installed on each support arm 102 and always faces outward.

[0069] Furthermore, the linkage device 3 also includes a plurality of mounting frames 302, one end of which is fixedly connected to the outer end of each linkage shaft 301; a linkage unit 4, which is connected to the support arm 102 and is used to keep each suction cup outward when the linkage shaft 301 rotates; a transmission unit 5, which is used to make each linkage shaft 301 rotate when the rotating seat 101 rotates axially, and each support arm 102 can be rotatably mounted on the other end of each mounting frame 302.

[0070] Furthermore, the transmission unit 5 includes a fixed toothed disc 501 , which is fixedly mounted on the frame 6 ; and a plurality of gears 502 , which are used to enable each linkage shaft 301 to cooperate with the fixed toothed disc 501 in transmission.

[0071] Furthermore, the linkage unit 4 includes a sleeve 401, which is rotatably mounted between the linkage shaft 301 and the rotating seat 101; a gear two 402, which is fixedly mounted on the outer end of the sleeve 401; a gear three 403, which is fixedly mounted on the support arm 102 and is transmission-connected to the gear two 402; a guide ring groove 404, which is arranged on the frame 6; and a transmission frame 405, one end of which is fixedly mounted on the inner end of the sleeve 401 and the other end of which is slidably mounted in the guide ring groove 404.

[0072] Furthermore, the driving device 2 includes a motor 201 mounted on the frame 6 ; a pulley 202 fixedly mounted on and connected to the output shaft of the motor 201 ; wherein the pulley 202 is connected to the rotating seat 101 via a transmission belt 203 .

[0073] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the motor 201 is powered on and operated, the pulley 202 drives the rotating seat 101 to rotate through the transmission belt 203, and each linkage shaft 301 rotates synchronously with the rotating seat 101, and each gear 1 502 is transmitted with the fixed toothed disc 501, so that the linkage shaft 301 rotates, and the mounting frame 302 rotates together with the linkage shaft 301, and the support arm 102 located at the other end of the mounting frame 302 swings periodically. At the same time, each transmission frame 405 slides in the guide ring groove 404, and each sleeve 401 adjusts its angle as each transmission frame 405 cooperates with the guide ring groove 404. Each support arm 102 is linked with each sleeve 401 under the cooperation of gear 2 402 and gear 3 403. When the mounting frame 302 makes a circumferential motion with the linkage shaft 301, each material grabbing suction cup 103 is kept facing outward;

[0074] The transmission frame 405 includes a fixing ring 405 a fixedly mounted on the outer wall of the inner end of the shaft sleeve 401 ; a guide rod 405 b , the top end of which is fixedly mounted on the fixing ring 405 a , and the other end of which is slidably matched with the guide ring groove 404 .

[0075] It should be explained in detail that, while the mounting frame 302 rotates circumferentially with the rotating seat 101, it also rotates circumferentially around the linkage shaft 301, and one end of the mounting frame 302 on which the support arm 102 is mounted periodically extends out of the rotating seat 101, and each material grabbing suction cup 103 maintains an outward posture. When the support arm 102 extends out of the rotating seat 101, the material grabbing suction cup 103 grabs the cardboard and then retracts with the support arm 102. When the material grabbing suction cup 103 approaches the product to be packaged, the support arm 102 extends to bring the material grabbing suction cup 103 close to the product to be packaged, and when the cardboard contacts the product to be packaged, the material grabbing suction cup 103 releases the material and retracts with the support arm 102, thereby grabbing and placing the cardboard.

[0076] Embodiment 2:

[0077] like Figures 2 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the frame 6 includes a fixed frame 7, one side of which is provided with a plurality of screw holes 601; a movable frame 602, the top of which is provided with a plurality of mounting grooves 603; a plurality of fasteners, which are movably inserted through the mounting grooves 603 and are connected to the screw holes 601 by threads, and the motor 201 is installed at the bottom of the movable frame 602, and the mounting grooves 603 are parallel to the length direction of the movable frame 602.

[0078] Furthermore, the fixed frame 7 includes a main body 701, which is provided with a slot 702 on the side away from the movable frame 602; a sliding frame 703, which can be slidably installed in the slot 702; a pillar 704, which is fixedly installed on the sliding frame 703, and the fixed gear disc 501 is installed on the sliding frame 703. The free end of the pillar 704 passes through the fixed gear disc 501 and is movably connected to the rotating seat 101 through a bearing.

[0079] Furthermore, the fixing frame 7 also includes a pair of slide grooves 705, which are respectively arranged at the top and bottom of the slot 702; a slide bar 706, which is arranged at the top of the sliding frame 703 and slides with the upper slide groove 705; a slider 707, which is arranged at the bottom of the sliding frame 703 and slides with the lower slide groove 705; and a locking mechanism 8, which is arranged on the main body 701 and is used to lock the slider 707.

[0080] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the transmission belt 203 is sleeved on the rotating seat 101 and the pulley 202. When the transmission belt 203 is loose, the fasteners are loosened. Under the cooperation of the fasteners and the mounting grooves 603, the movable frame 602 slides to increase the distance between the motor 201 and the rotating seat 101 until the transmission belt 203 is tightened, and then the fasteners are tightened to fix the movable frame 602.

[0081] Secondly, when gear 1 502, gear 2 402 or gear 3 403 needs to be replaced due to long-term wear, first loosen the fasteners (not shown in the figure), move the sliding frame 703, make the motor 201 close to the rotating seat 101, loosen the transmission belt 203, operate the locking mechanism 8, release the fixation of the slider 707, drag the sliding frame 703 to extend out of the mounting slot 603, and the slide bar 706 and the slider 707 slide in the upper and lower slide slots 705 respectively until the gear 1 502, gear 2 402 and gear 3 403 located on the back of the rotating seat 101 are exposed. At this time, operate the locking mechanism 8 to fix the slider 707 to fix the position of the sliding frame 703, so as to facilitate the replacement of the excessively worn gear 1 502, gear 2 402 and gear 3 403.

[0082] Embodiment 3:

[0083] like Figure 3 and Figure 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the locking mechanism 8 includes a lifting groove 801, which is arranged on the outer wall of the main body 701 and is connected to the lower slide groove 705; a plurality of lifting blocks 802, which can be lifted and installed between the lower slide groove 705 and the lifting groove 801; and a plurality of springs 803, which are arranged between the bottom end of each lifting block 802 and the bottom end of the lifting groove 801.

[0084] Furthermore, the locking mechanism 8 also includes a pair of grooves 804, which are respectively arranged on the side walls at both ends of the lifting groove 801; a plurality of transmission grooves 805, which are arranged at the top of each lifting block 802, and the bottom is inclined to the same side; a slide bar 806, the middle part of which is slidably installed in each transmission groove 805, and the two ends are respectively movably inserted in each groove 804; a plurality of guide grooves 807, which are arranged at intervals on the slide bar 806 for transmission cooperation with each transmission groove 805; a push-pull rod 808, which is fixedly installed on the outer wall of the slide bar 806.

[0085] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the restriction on the slider 707 needs to be released, the slider 806 is pushed and pulled by the push-pull rod 808 to make it slide horizontally, and the guide grooves 807 located on the bottom surface thereof cooperate with the bottom ends of the transmission grooves 805 to push the lifting blocks 802 to retract from the lower slide grooves 705 to the lifting groove 801, and the top ends of all lifting blocks 802 are not higher than the bottom end surface of the slider 707. At this time, the slider 707 can slide in the slide groove 705 along the extension direction of the slide groove 705;

[0086] When it is necessary to fix the slider 707, the push-pull rod 808 is released, and each spring 803 exerts elastic potential energy, so that each lifting block 802 rises in the lifting slot 801, and the top end extends into the lower slide slot 705. At the same time, the transmission slot 805 cooperates with each guide slot 807 to push the slide bar 806 upward and return to the initial position. The top end of the lifting block 802 located directly below the slider 707 contacts the top end of the slider 707, and the top ends of the other lifting blocks 802 extend into the lower slide slot 705. The adjacent side walls of each lifting slider 707 contact and fit each other, the side walls of the lifting sliders 707 located on both sides of the slider 707 contact and fit with the side walls of the slider 707, and the side walls of the lifting blocks 802 located at the two ends of the lifting slot 801 contact and fit with the side walls at both ends of the lifting slot 801, so that the slider 707 is fixed and cannot slide in the slide slot 705.

[0087] The width of the slider 707 is greater than the width of the guide slot 807 , so that the top end of the lifting block 802 can contact and abut against the bottom end of the slider 707 .

[0088] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

In addition, the features described with reference to certain examples may be combined in other examples.

[0089] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
