[0010] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0011] like Figures 1 to 3 The rotating structure 2 for packing the box shown includes a circular track ring 21 mounted on the side plate 117 (e.g., a connecting block 211 is fixed to the back of the circular track ring 21, and the circular track ring 21 is mounted on the side plate 117 using fasteners such as bolts and fittings with the connecting block 211), and a circular rotating ring 22 rotatably mounted on the circular track ring 21 (the connection between the circular rotating ring 22 and the circular track ring 21 can be conventional, preferably with a raised ring formed on the outer circumferential surface of the circular track ring 21, and on the circumferential surface of the raised ring...). Multiple steel balls are embedded at equal intervals. A groove is opened on the inner surface of the circular rotating ring 22 to cooperate with the convex ring, so that the groove wall is in contact with the surface of the steel ball. In this way, the circular rotating ring 22 can rotate on the circular track ring 21 under the action of external force. A tape seat assembly 23 is installed on the circular rotating ring 22 for installing the tape roll 0. A first drive unit 24 is installed on the side plate 117 for driving the circular rotating ring 22 to rotate. When the first drive unit 24 works, it can drive the circular rotating ring 22 to rotate relative to the circular track ring 21.

[0012] In this embodiment, the tape holder assembly 23 includes an adapter block 231 mounted on the side of the circular rotating ring 22 (facing the side of the operating table 13), a support plate 232 mounted on the adapter block 231 and extending outward (the straight line of the extension direction of the support plate 232 preferably passes through the center of the circular rotating ring 22), a mounting shaft 233 mounted on the support plate 232 (located at the outer end of the support plate 232) and perpendicular to it (the mounting shaft 233 also faces the operating table 13), and a tape holder 234 rotatably fitted onto the mounting shaft 233 (the rotatability is conventional, such as opening a mounting hole with a diameter slightly larger than the diameter of the mounting shaft 233 at the axis of the tape holder 234, so that the tape holder 234 can be directly fitted onto the mounting shaft 233); and a tape roll. 0 is mounted on tape holder 234), an extension plate 235 rotatably mounted on mounting shaft 233 and cooperating with support plate 232 (such as one end of extension plate 235 being pivotally connected to mounting shaft 233), a feed lever 236 mounted on the free end of extension plate 235 and parallel to mounting shaft 233, and a spring connected at one end to support plate 232 and the other end to extension plate 235 (the spring connects support plate 232 and extension plate 235 so that when tape holder assembly 23 rotates with circular rotating ring 22, the angle between support plate 232 and extension plate 235 can change within a small range, and the feed lever 236 is used to make the tape in a suitable tension state, with the non-adhesive surface of the tape contacting the feed lever 236).

[0013] In this embodiment, the first drive unit 24 includes a motor mounting plate 241 installed in the support assembly 1 (specifically, the motor mounting plate 241 is installed on the support vertical plate 114), a first drive wheel 242 rotatably mounted on the motor mounting plate 241 (installed in a conventional manner, such as directly mounted on the output shaft of the first motor 243), a first motor 243 mounted on the motor mounting plate 241 and connected to the first drive wheel 242 (when the first motor 243 is working, it can drive the first drive wheel 242 to rotate synchronously), a first driven wheel 244 rotatably mounted on the side plate 117 and located on both sides of the circular rotating ring 22 (there are two first driven wheels 244, which are spaced apart and mounted on the side plate 117 in a pivotal manner, such as a mounting shaft passing through the center), and a first transmission belt 245 wound around the two first driven wheels 244 and the first drive wheel 242 and in contact with the circumference of the circular rotating ring 22. Because the two first driven wheels 244 are higher than the bottom of the circular ring 22, the horizontal plane where the center lines of the two first driven wheels 244 are located passes through and separates the circular ring 22. This allows the first transmission belt 245 to be in close contact with the circumference of the circular ring 22. When the first transmission belt 245 rotates under the drive of the first motor 243 (one-way motor), the friction between the first transmission belt 245 and the circular ring 22 drives the circular ring 22 to rotate on the circular track ring 21. The above structure can improve the stability and reliability of rotation (i.e., winding).

[0014] The aforementioned rotating structure 2 for box packaging can be used to manufacture a box wrapping machine. Thus, the box wrapping machine mainly includes a matching support assembly 1, a rotating structure 2 for box packaging, a wrapping limiting assembly 3, a tape pressure roller assembly 4, a clamping and cutting assembly 5, and a tape brush assembly 6, etc.

[0015] The support assembly 1 has a side support plate 117. Specifically, the support assembly 1 includes a support box 11, a plurality of traveling rollers 12 (two in this application, which can be installed at the two corners of the bottom of the support box 11 in a conventional manner; preferably fixed by an upright support profile) installed at the bottom of the support box 11, and an operating table 13 installed at the top of the support box 11.

[0016] The support box 11 includes a support base plate 111, a support middle plate 112 disposed above the support base plate 111 (the operating table 13 is located above the support middle plate 112, thus the operating table 13, the support middle plate 112, and the support base plate 111 form a three-layer structure), multiple horizontal auxiliary blocks 115 disposed on one side of the support base plate 111 (in this application, there are two blocks spaced apart, which, along with the two traveling rollers 12, are located on opposite sides of the support base plate 111), and multiple adjusting feet 116 installed on each horizontal auxiliary block 115 (in this application, there are also two adjusting feet 116, which are installed one-to-one on the horizontal auxiliary block 115, thereby cooperating with the traveling rollers 12 to achieve support). The support for the box body 11 includes: multiple traveling rollers 12 mounted on the support base plate 111 and opposite to multiple adjusting feet 116; a box cover plate 113 covering the sides of the support base plate 111 and the support middle plate 112 and extending to contact the operating table 13; side baffles 118 mounted on the box cover plate 113 and located on both sides of the side support plate 117; and a support vertical plate 114 mounted between the support base plate 111 and the support middle plate 112. The side support plate 117 is mounted on the sides of the support base plate 111 and the support middle plate 112 and extends vertically upward. Thus, the side support plate 117, the box cover plate 113, the operating table 13, and the support base plate 111 form the main structure of the support box body 11.

[0017] The winding limiting assembly 3 is mounted on the support assembly 1 and is used to place the box 1' (the box to be wrapped with tape). The winding limiting assembly 3 includes a support pad 31 mounted on the side plate 117 by multiple reinforcing blocks 32 and cooperating with the operating table 13 (the support pad 31 and the operating table 13 are on the same horizontal plane and are spaced apart to form a certain operating space (such as for the passage of tape or other structures)) and clearance holes 33 opened on the side plate 117 and corresponding to the support pad 31 (the size of the clearance hole 33 usually corresponds to the maximum size of the box 1' that can be handled).

[0018] The rotating structure 2 used for box packaging can be the same as described above.

[0019] The tape pressure roller assembly 4 is installed inside the support assembly 1, and its projection on the side carrier plate 117 is located within the circular track ring 21. The tape pressure roller assembly 4 includes a fixed seat installed inside the support assembly 1 (the fixed seat is installed on the side of the support profile 61 described below, not shown in the figure), multiple limiting rods 41 installed between the fixed seat and the side carrier plate 117 and spaced apart (in this application, there are two limiting rods 41, which are spaced apart and located in the same horizontal plane; one end of each limiting rod 41 is installed on the fixed seat and the other end is installed on the side carrier plate 117), an anti-slip sleeve 42 sleeved on each limiting rod 41, and a limiting ring 44 installed on any limiting rod 41 and cooperating with the tape seat assembly 23 (the limiting ring 44 is installed on the limiting rod 41 near the tape seat assembly 23). When the box wrapping machine is used for the first time, the tape roll 0 on the tape seat 234 needs to be released manually so that the tape (especially the free end of the tape) is pulled to the lower part of the limit link 41 via the feed bar 236.

[0020] The clamping and cutting component 5 is adjustablely installed in the support component 1 and cooperates with the tape pressure roller component 4 to clamp the tape and cut it after winding it one or more times. In this embodiment, as mentioned above, when the tape is pulled to the lower part of the limiting link 41, the clamping and cutting component 5 is operated to cooperate with the limiting link 41 to clamp the tape and cut off a small portion of the free end of the tape at the same time, so as to avoid the free end of the tape not meeting the usage requirements when it is first used (such as the tape roll 0 being easily damaged when manually starting). Specifically, the clamping and cutting assembly 5 includes a base 51 installed within the support assembly 1 (i.e., installed on the support middle plate 112, there are two bases 51 arranged opposite each other and spaced apart), a second drive wheel 52 rotatably mounted on the base 51 (installed in a conventional manner, such as directly mounted on the output shaft of the second motor 53), a second motor 53 mounted on the base 51 (mounted on any one of the bases 51) and connected to the second drive wheel 52, a second driven wheel 58 rotatably mounted on the base 51 (there is one second driven wheel 58, which is pivotally mounted on any one of the bases 51, such as having a mounting shaft passing through the center, so that both ends of the mounting shaft are respectively mounted on the base 51), and a second transmission belt 54 wound around the second drive wheel 52 and the second driven wheel 58 (so that when the second motor 53 is working...). The system includes a second drive belt 54 that drives the second driven wheel 58 to rotate synchronously, a swing arm 59 mounted on the side of the second driven wheel 58 (the swing arm 59 is mounted on the side of the second driven wheel 58 by bolts or other fasteners), a serrated blade 55 mounted on the upper end (i.e., the free end) of the swing arm 59 and corresponding to the limiting link 41, a base block 56 mounted on the side of the swing arm 59, and a clamping block 57 mounted on the base block 56 and cooperating with the limiting link 41. When the second driven wheel 58 rotates, it can drive the swing arm 59 to rotate synchronously, moving away from the two limiting links 41 (to facilitate clamping the tape) or moving between the two limiting links 41 (and then using the serrated blade 55 to cut the tape, so that a small portion of the free end of the tape is cut off). At this time, the clamping block 57 and the serrated blade 55 move synchronously (i.e., clamping the tape and cutting the tape are performed synchronously).

[0021] The tape brush assembly 6 includes at least a slide rail 62 installed inside the support assembly 1 (conventionally installed in the support housing 11) and parallel to the circular track ring 21 (the slide rail 62 is also preferably supported on the two bases 51 mentioned above and cooperates with the swing arm 59, which can be used to assist in limiting the swing arm 59 and prevent the serrated blade 55 from moving too upward and potentially damaging the carton), a brush holder 67 reciprocally slidably installed on the slide rail 62, and a tape brush head 69 installed on the brush holder 67 and cooperating with the clamping and cutting assembly 5 (mainly the clamping block 57). The tape application assembly 6 also includes a support profile 61 installed in the support assembly 1 (the support profile 61 is conventionally installed in the support housing 11, and the slide rail 62 is installed on the support profile 61), two drive wheel seats 63 installed on the side of the support profile 61 and spaced apart, a third driven wheel 64 installed on one drive wheel seat 63, a third driving wheel installed on the other drive wheel seat 63, a third motor 66 installed on the other drive wheel seat 63 and connected to the third driving wheel, and a third transmission belt 65 wound around the third driving wheel and the third driven wheel 64; the drive wheel seat 63 on which the third driven wheel 64 is installed has an oblong hole, and the third driven wheel 64 has a central shaft inserted into the oblong hole, so that the third driven wheel 64 can move slightly on the drive wheel seat 63, avoiding the third transmission belt 65 from always being in a taut state, which is beneficial to improving its service life. The brush holder 67 includes a slider 671 slidably mounted on the slide rail 62 and connected to the third transmission belt 65, an outer extension plate 672 mounted on the slider 671 and perpendicular to the slide rail 62, a clamping plate 673 mounted on the outer extension plate 672 and forming a gap, and a brush fixing seat 674 mounted in the gap. The tape brush head 69 is mounted on the brush fixing seat 674. When the third motor 66 is working, it can drive the third transmission belt 65 to rotate, thereby driving the slider 671 to move back and forth on the slide rail 62, so that the tape brush head 69 slides back and forth.

[0022] The tape application assembly 6 also includes two limit sensors 68 mounted on the side of the support profile 61 and spaced apart, for limiting the sliding stroke of the slider 671. Each limit sensor 68 includes a sensor mounting base 681 mounted on the side of the support profile 61 and a sensor 682 mounted on the sensor mounting base 681. According to existing conventional control methods, the box wrapping machine also preferably includes an existing conventional controller, which is connected to the sensor 682 and to each motor, for receiving signals sent by the sensor 682 and realizing the control of each motor (such as the first motor 243 (the first motor 243 is usually a unidirectional motor), the second motor 53, the third motor 66 (the second motor 53 and the third motor 66 are usually bidirectional motors), etc.

[0023] Initially, the clamping block 57 and a limiting link 41 (on the left) manually clamp the tape, while the serrated blade 55 cuts the tape, removing the free end (forming a cutting head). The circular rotating ring 22 rotates at a certain angle (usually ≤45°) driven by the first transmission belt 245. The brush holder 67 moves from left to right driven by the third motor 66, and the tape brush head 69 gradually approaches and contacts the tape, brushing it onto the bottom surface of the housing 1'. The serrated blade 55 and the base block 56 move downwards driven by the swing arm 59, with the serrated blade 55 moving below the limiting link 41, and the clamping block 57 separating from the limiting link 41 (i.e., the front part). The tape pressure roller assembly 4, the clamping and cutting assembly 5, and the tape brush assembly 6 all improve the automation level and production efficiency of the winding machine.

[0024] The circular rotating ring 22 continues to rotate until the tape comes into contact with the anti-slip sleeves 42 of the two limiting rods 41; the brush holder 67 moves from right to left under the drive of the third motor 66, and the tape brush head 69 gradually approaches and contacts the tape to brush the tape onto the bottom surface of the box 1'; the serrated blade 55 and the base block 56 move upward under the drive of the swing arm 59, the serrated blade 55 cuts the tape, and the clamping block 57 and the limiting rods 41 clamp the tape; the cutting head here is aligned with the aforementioned cutting head to achieve a loop of tape wrapped around the box 1' (i.e., the rear part).

[0025] When multiple turns of tape need to be wrapped around the housing 1', the actions in the first part are the same, except that the two limiting rods 41 need to be set to be able to lift up and down (such as setting a conventional lifting structure below the tape pressure roller assembly 4 and the clamping and cutting assembly 5). When the brush seat 67 moves from left to right under the drive of the third motor 66, the tape brush head 69 gradually approaches and contacts the tape, so that the tape is brushed onto the bottom surface of the housing 1'. Then, the tape pressure roller assembly 4 and the clamping and cutting assembly 5 move downward under the drive of the lifting structure and are lower than the circular rotating ring 22. After the tape is wrapped to the required number of turns, the tape pressure roller assembly 4 and the clamping and cutting assembly 5 move upward under the drive of the lifting structure. The actions in the second part can then be performed.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
