Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an electric wrapping machine. Background Art

[0002] A tape wrapping machine is an automated or semi-automated device designed to wrap tape around boxes, wire harnesses, cables, or other objects. The machine's operating principle is to place the object in the center of a turntable. The motor is activated to rotate the turntable, and the tape is continuously wrapped around the object until it reaches the desired number of layers or length. The tape is then cut, completing the wrapping process.

[0003] Traditional tape winding machines are usually equipped with a lifting cylinder and a pressing plate, such as a tape winding machine with patent application number CN202421638212.8. The lifting cylinder is fixedly installed behind the fixed plate and a pressing plate is fixed at the bottom. When working, the lifting cylinder is started to drive the pressing plate downward to stably press the object on the placement table to prevent the object from moving during the winding process.

[0004] However, this method of using a lifting cylinder to control the pressing plate has certain limitations. Due to the limited stroke of the lifting cylinder, the pressing plate may not be able to effectively contact and fix objects of lower heights, thereby affecting the winding effect. If the stroke of the pressing plate is to be increased to accommodate objects of different heights, a longer lifting cylinder is required, which not only increases the total volume of the equipment, but may also cause the equipment structure to become bulky and inconvenient to operate and carry. This is not ideal for some working environments with limited space. In response to the above technical problems, this application makes improvements. Utility Model Content

[0033] The following is a combination of the appended examples of the present invention Figure 1-10 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example:

[0035] like Figures 1 to 10 As shown, the utility model discloses an electric winding machine, comprising a base 11, a stand 12 fixedly connected to the base 11, and a placement opening 121 opened in the middle of the stand 12 for accommodating articles to be wound, wherein, as shown in FIG. Figure 4 and Figure 6As shown, a transmission mechanism is provided on the left and right sides of the placement port 121 on the back of the stand 12, and each transmission mechanism includes a synchronous belt 21 and a synchronous pulley 22. Two synchronous pulleys 22 are provided for the two transmission mechanisms and are respectively rotatably arranged on the upper and lower sides of the placement port 121, and the synchronous belt 21 is cooperatively arranged between the two synchronous pulleys 22. A driving mechanism for driving the synchronous pulleys 22 to rotate is provided on the stand 12, and a cross bar 23 is provided between the two transmission mechanisms. The left and right ends of the cross bar 23 are respectively fixedly connected to the synchronous belts 21 of the two transmission mechanisms, and a pressing plate 31 is provided in the middle of the cross bar 23.

[0036] Furthermore, guide rails 24 are vertically provided on the left and right sides of the placement opening 121 on the back of the stand 12, and sliders 241 are fixedly connected to the left and right ends of the cross bar 23. The sliders 241 slide on the guide rails 24. This structure is used to ensure that the cross bar 23 slides smoothly in the vertical direction.

[0037] Furthermore, the driving mechanism specifically includes a reduction motor 25, a driving pulley 26, a driven pulley 27, a driving synchronous belt 28 and a connecting rod 29. The two ends of the connecting rod 29 are respectively fixedly connected to the synchronous pulleys 22 located on the upper side of the two transmission mechanisms, and the driven pulley 27 is fixedly connected to the connecting rod 29. The reduction motor 25 is fixed on the stand 12, the driving pulley 26 is fixedly connected to the output shaft of the reduction motor 25, and the driving synchronous belt 28 is cooperatively arranged between the driving pulley 26 and the driven pulley 27. The connecting rod 29 is driven by the rotation of the reduction motor 25, thereby driving the two synchronous pulleys 22 to rotate and driving the synchronous belt 28 to move up and down.

[0038] like Figure 10 As shown, a guide sleeve 32 is fixedly connected to the middle part of the cross bar 23, and a sliding column 33 is movably fitted on the lower side of the guide sleeve 32. A pressing plate spring 34 is provided between the sliding column 33 and the guide sleeve 32. The pressing plate 31 is fixed under the sliding column 33. In addition, a stop plate 35 is fixedly connected to the pressing plate 31. A proximity switch 36 is provided on the cross bar 23. The pressing plate spring 34 enables the pressing plate 31 to press objects and prevents the pressing plate 31 from damaging objects. In addition, when the stop plate 35 approaches the proximity switch 36, the proximity switch 36 sends a signal to stop the reduction motor 25 and drive the cross bar 23 to continue downward.

[0039] like Figure 1 、 Figure 2 as well as Figure 5As shown, a rotating ring 41 is rotatably provided on the front side of the stand 12 and surrounds the outer periphery of the placement port 121. A tape placement rack 42 is fixedly connected to the rotating ring 41 for placing the tape. An inner ring 43 is fixedly provided on the stand 12 and abuts against the inner side of the rotating ring 41. In addition, a plurality of rotating wheels 44 are rotatably connected to the stand 12 and abut against the outer side of the rotating ring 41 to provide support stability. Figure 6 As shown, two rotating ring motors 45 are fixedly connected to the back side of the stand 12. The output shafts of the two rotating ring motors 45 penetrate into the front side of the stand 12 and are fixedly connected to a friction wheel 46. The friction wheel 46 is in conflict with the outer side of the rotating ring 41. The friction wheel 46 is driven by the motor to rotate, driving the rotating ring 41 and the tape placement rack 42 to rotate synchronously, thereby realizing the winding of the tape.

[0040] like Figure 1 As shown, the base 11 is fixedly connected to storage racks 13 on the front and rear sides of the stand 12. There is a tape passage gap 131 between the two storage racks 13 for the tape to pass through and wrap around the items. In addition, the stand 12 is provided with a tape support assembly on the lower side of the placement opening 121, and a tape cutting mechanism is provided on the lower side of the tape support assembly.

[0041] Specifically, such as Figure 2 、 Figure 4 、 Figure 5 as well as Figure 9 As shown, the tape support assembly includes a tape support frame 51, a movable roller frame 52, a tape support motor 53, a roller frame guide rail 54, a linkage rod assembly 55, a first roller shaft 56 and a second roller shaft 57. The vertical frame 12 is provided with an installation opening 122 on the lower side of the placement opening 121, and the tape support frame 51 is fixedly installed on the installation opening 122. The roller frame guide rail 54 is fixed on the tape support frame 51 in the front-to-back direction, and the movable roller frame 52 is movably arranged on the roller frame guide rail 54. The tape support motor 53 is fixed on the rear side of the tape support frame 51 and is connected to the movable roller frame 52 through the linkage rod assembly 55. The first roller shaft 56 is fixed on the movable roller frame 52. The first tape roller 561 is rotatably connected to the first roller shaft 56. The second roller shaft 56 is fixedly connected to the second roller shaft bracket 58. The second roller shaft 57 is fixedly connected to the second roller shaft bracket 58. The second tape roller 571 is rotatably connected to the second roller shaft 57.

[0042] The specific structure of the second roller bracket 58 fixed on the first roller 56 is: the second roller bracket 58 is provided with a connecting port 581 which is sleeved on the first roller 56 and a locking gap 582 which passes through the second roller bracket 58 to the connecting port 581. The second roller bracket 58 is provided with bolt through-holes on both sides of the locking gap 582. The second roller bracket 58 can be fixed to the first roller 56 by the cooperation of the bolts and the bolt through-holes. The upper and lower positions of the second roller 57 can be adjusted after loosening the bolts, so that the cutter 62 can better cut the tape.

[0043] In addition, the tape cutting mechanism specifically includes a cutter frame 61, a cutter 62, a first stop block 63, a rotating connecting rod assembly 64 and a cutter motor 65. The base 11 is fixedly connected to the component frame 14 on the front side of the vertical frame 12, and the cutter frame 61 is rotatably connected to the component frame 14. The cutter 62 is fixed on the cutter frame 61 and is correspondingly located on the lower side between the first tape roller 561 and the second tape roller 571. The cutter frame 61 is also fixedly connected to the first stop block 63 located on the lower side of the first tape roller 561. The cutter motor 65 is fixed on the component frame 14 and is connected to the cutter frame 61 through the rotating connecting rod assembly 64.

[0044] The cutter frame 61 is fixedly connected to a stop bracket 66. A movable notch 631 is defined in the middle of the first stop 63. A limiting post 611 is fixedly connected to the cutter frame 61 and movably engages within the movable notch 631. A movable spring 67 is disposed between the stop bracket 66 and the first stop 63. The cutter motor 65 rotates the cutter frame 61 by rotating the connecting rod assembly 64, causing the cutter 62 to move upward between the first and second tape rollers 561, 571, and cut the tape. During this process, the first stop 63 first contacts the first tape roller 561, effectively limiting the travel distance of the cutter 62. The first stop 63 and the stop bracket 66 are in a floating engagement, preventing damage to the first tape roller 561. After the first stop 63 contacts the first tape roller 561, the spring is compressed downward, and the cutter 62 continues upward to cut the tape between the first and second tape rollers 561, 571.

[0045] In the present invention, a transverse guide rail 71 is fixedly connected to the storage rack 13 on the front side of the vertical frame 12, and an adhesive bracket 72 is slidably fitted on the transverse guide rail 71, and an adhesive roller 73 is rotatably connected to the adhesive bracket 72. In addition, the storage rack 13 on the front side of the vertical frame 12 is rotatably connected to adhesive pulleys 74 at both ends of the transverse guide rail 71, and a driving pulley 75 and a tensioning pulley 76 are rotatably fitted on the component rack 14. In addition, the component rack 14 is equipped with an adhesive roller driving motor 77 connected to the driving pulley 75, and an adhesive roller driving synchronous belt 78 is provided between the driving pulley 75, the tensioning pulley 76 and the adhesive pulley 74. The adhesive roller driving synchronous belt 78 is connected to the adhesive bracket 72, driving the adhesive roller 73 to move along the transverse guide rail 71 from left to right, and then from right to left, to fit the bottom of the article and to bond the end of the tape to fix it.

[0046] The working principle of this utility model is as follows:

[0047] When using the device for the first time or just changing the tape, you need to pull out a part of the tape and stick it on the lower side of the first tape roller 561 in the tape support assembly before working.

[0048] 1. Item placement and pressing:

[0049] Place the article to be wrapped in the placement opening 121 in the middle of the stand 12 , and ensure that the tape winding position is aligned with the tape passing gap 131 .

[0050] The reduction motor 25 is activated, driving the active pulley 26, which in turn rotates the passive pulley 27 via the synchronous belt 28. The connecting rod 29 then rotates the upper synchronous pulleys 22 of the two transmission mechanisms. The synchronous belt 21 then moves the crossbar 23 up and down. The crossbar 23 slides stably through the cooperation of the slider 241 and the guide rail 24, driving the pressing plate 31 downward to press and secure the object.

[0051] 2. Tape winding:

[0052] The rotating ring motor 45 is started, and the rotating ring 41 is driven to rotate through the friction wheel 46, which drives the tape placement rack 42 to rotate synchronously. The tape is wound around the surface of the object as the rotating ring 41 rotates.

[0053] When the rotating ring 41 drives the tape placement rack 42 to rise to a height above the bonding roller 73, the bonding roller driving motor 77 is started, and the bonding bracket 72 is driven to move from left to right along the transverse guide rail 71 through the driving pulley 75 and the bonding roller driving synchronous belt 78. During the movement, the transverse guide rail 71 drives the bonding roller 73 to slide along the bottom of the article. The bonding roller 73 is higher than the first tape roller 561 and the second tape roller 571. When the bonding roller 73 slides from the left to the rightmost side along the bottom of the article, the tape that was initially adhered to the lower side of the first tape roller 561 can be adhered to the bottom of the article.

[0054] Next, the tape support motor 53 drives the movable roller frame 52 backward along the roller frame guide rail 54 via the linkage rod assembly 55, causing the first tape roller 561 and the second tape roller 571 to leave the tape winding path to avoid interference. Therefore, when the rotating ring 41 drives the tape to the bottom of the object, the tape can be directly wound around the bottom of the object. As the rotating ring 41 drives the tape to rotate a specified number of times, the movable roller frame 52 moves forward, and the first tape roller 561 and the second tape roller 571 re-enter the winding path. This time, when the rotating ring 41 drives the tape placement frame 42 back to its original position, the last lower tape loop will bypass the first tape roller 561 and the second tape roller 571. It should be noted that if the tape is only wound once, the first tape roller 561 and the second tape roller 571 do not need to move backward.

[0055] 3. Tape cutting:

[0056] When the winding reaches the preset number of turns, the cutter motor 65 drives the cutter frame 61 to rotate by rotating the connecting rod assembly 64, and the cutter 62 moves upward to between the first tape roller 561 and the second tape roller 571. The first stop block 63 first contacts the first tape roller 561, compressing the spring downward, and the cutter 62 continues to cut the tape upward.

[0057] 4. Adhesion of the tape end:

[0058] After the cutter 62 is reset, the bonding roller drive motor 77 is started again, driving the bonding roller 73 to move from right to left, bonding the cut tape end (that is, the portion of tape stuck on the second tape roller 571) to the bottom of the object, completing the winding process.

[0059] The cutter motor 65 drives the cutter frame 61 to rotate downward and reset by rotating the connecting rod assembly 64. At this time, the items can be taken out and new items can be put on for the next round of packaging.

[0060] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
