Technical Field

[0001] This utility model relates to the field of wrapping equipment technology, and more specifically, to an automatic wrapping equipment for bobbins. Background Technology

[0002] After the wires are processed, they are wound onto a spool. During the packaging process, the spool needs to be wrapped with cling film to provide protection. Currently, manual wrapping is a common practice.

[0003] Although manual wrapping is common, the packaging methods vary due to differences in the workers. Secondly, the monotonous nature of the work method can lead to worker fatigue and make it difficult to maintain consistency in the work method. In addition, the work efficiency is low. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automatic spool wrapping device to solve the problems of inconsistent packaging and low efficiency in the existing wire wrapping technology. The device provided by this utility model can achieve rapid wrapping, and its simple structure makes it easy to maintain and operate.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic spool wrapping device includes:

[0007] Base plate;

[0008] A circular ring, which is rotatably mounted on the base plate;

[0009] A bobbin fixing assembly is disposed on the base plate and located at the center of the ring, for placing the bobbin to be wrapped with film;

[0010] A film roll assembly is mounted on a ring, and plastic wrap is wound around the film roll assembly;

[0011] A circular drive component is mounted on the base plate to drive the circular ring to rotate, thereby driving the film roll assembly winding shaft fixing assembly to rotate, so as to wrap the plastic wrap around the spool.

[0012] A film cutting assembly is provided on the base plate for cutting the plastic wrap after the spool has finished wrapping the plastic wrap.

[0013] Furthermore, the circular drive component includes a motor mounting base, a motor, a drive wheel, a driven wheel, and a belt.

[0033] The structure provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0034] refer to Figure 1 and Figure 2As shown, this embodiment specifically discloses an automatic bobbin wrapping device, including:

[0035] Base plate 1;

[0036] Ring 2 is rotatably mounted on base plate 1;

[0037] The bobbin fixing assembly 3 is set on the base plate 1 and located at the center of the ring 2, and is used to place the bobbin to be wrapped (not shown in the figure);

[0038] A film roll assembly 4 is mounted on a ring 2, and a plastic wrap 41 is wrapped around the film roll assembly 4.

[0039] The circular drive component 5 is mounted on the base plate 1 and is used to drive the circular ring 2 to rotate, thereby driving the film roll assembly 4 and the winding shaft fixing assembly 3 to rotate, so as to wrap the plastic wrap 41 on the spool.

[0040] The film cutting assembly 6 is set on the base plate 1 and is used to cut the plastic wrap 41 after the spool is wrapped.

[0041] Understandably, the device can also be equipped with a master switch. When operating the device, the master switch is turned on first. The operator can manually wrap one end of the plastic wrap 41 around the spool, then fix the spool on the spool fixing assembly 3. Then, the ring drive 5 is activated, which drives the ring 2 to rotate, thereby driving the film roll assembly 4 to rotate around the central spool. At this time, the spool is fixed on the central spool fixing assembly 3 and will not rotate. The film roll assembly 4 on the ring 2 will continuously release the plastic wrap 41 as the ring 2 rotates. The released plastic wrap 41 can automatically wrap around the spool as the ring 1 rotates, thus realizing the automatic wrapping of the plastic wrap 41. After the wrapping is completed, the drive film cutting assembly 6 can cut the plastic wrap 41. Overall, it can greatly increase the work efficiency and improve the consistency, synchronization and standardization of the work.

[0042] In this embodiment, the film roll assembly 4 includes a winding support 42 fixed on the ring 2, a mandrel 43 vertically arranged on the winding support 42, a plastic wrap 41 wound on the mandrel 43, and a fixing ring handle 44 connected to the upper end of the mandrel 43; the whole assembly facilitates the replacement of the mandrel 3 and the plastic wrap 41, and the setting of the fixing ring handle 44 also facilitates the initial manual winding of the plastic wrap 41 onto the spool.

[0043] Continue to refer to Figure 1As shown, in some embodiments, the circular drive component 5 includes a motor mounting base 51, a motor 52, a drive wheel 53, a driven wheel 54, and a belt 55. The motor mounting base 51 is mounted on the lower end of the base plate 1, the motor 52 is fixed on the motor mounting base 51, the drive wheel 53 and the driven wheel 54 are both located on the upper end surface of the base plate 1, the output end of the motor 52 passes through the base plate 1 and is connected to the drive wheel 53 for transmission, and the belt 55 is wound around the drive wheel 53 and the driven wheel 54, and at least part of the belt 55 can engage with the outer side wall of the circular ring 2 to drive the circular ring 2 to rotate.

[0044] Specifically, the drive motor 52 rotates, which drives the drive wheel 54 to rotate, and then drives the belt 55 to drive the drive wheel 53 and the driven wheel 54. This causes the belt 55 to work with the ring 2 through friction, thus driving the ring 2 to rotate (note that the belt 55 and the ring 2 run in opposite directions).

[0045] In the illustrated embodiment, there are two driven wheels 54, which are arranged in a triangular pattern with one driving wheel 53. A belt 55 is wound between the two driven wheels 54 and the driving wheel 53, so that the belt 55 can engage more and better with the outer wall of the ring 2, providing greater friction to drive the ring 2 to rotate.

[0046] In some embodiments, the circular drive component 5 further includes a plurality of rollers 56, which are distributed at intervals along the circumference of the circular ring 2 and roll in contact with the outer peripheral sidewall of the circular ring 2. By setting a plurality of circumferentially spaced rollers 56, the circular ring 2 can be guided, limited and supported. When the belt 55 drives the circular ring 2 to rotate, the sliding friction between the circular ring 2 and the base plate 1 (if the rollers 56 are not set, an annular groove adapted to the circular ring 2 can be set on the base plate 1, and the circular ring 2 can be directly installed in the annular groove. Of course, the depth of the annular groove is less than the height of the circular ring 2, so that the belt 55 can fit against the outer sidewall of the circular ring 2. At this time, the friction between the circular ring 2 and the base plate 1 is sliding friction) is converted into rolling friction between the circular ring 2 and the rollers 56, thereby reducing the friction between the circular ring 2 and other components during rotation and ensuring the transmission efficiency between the belt 55 and the circular ring 2.

[0047] Optionally, in some embodiments, components such as balls can be directly installed in the annular groove to reduce friction and ensure transmission between the belt 55 and the ring 2.

[0048] In some other embodiments, other driving components may be used, as long as they can drive the ring 2 to rotate at a uniform and stable speed.

[0049] Continue to refer to Figure 1 As shown, the bobbin fixing assembly 3 includes a fixing base 31, and a support 32 is detachably connected to the upper end face of the fixing base 31. A bobbin limiting post 33 is provided on the support 32.

[0050] The support 32 is detachable, which makes it easy to adjust different bobbin limit posts 33 according to the bobbin model. That is, when it is necessary to perform film wrapping operation on bobbins of different specifications, it is only necessary to replace different supports 32 and bobbin limit posts 33.

[0051] In the illustrated embodiment, the bobbin limiting post 33 is cylindrical and at least two are provided, preferably two in this embodiment; correspondingly, limiting holes are symmetrically provided on the upper and lower sides of the bobbin, and the limiting holes match the bobbin limiting post 33, so that the bobbin can be stably placed on the support 32, which facilitates the subsequent wrapping of the plastic wrap.

[0052] Optionally, in some embodiments, the cross-section of the bobbin limiting post 33 may be rectangular, and the corresponding limiting pick-and-place hole on the bobbin may also be rectangular, as long as the shape of the limiting pick-and-place hole matches that of the bobbin limiting post 33.

[0053] Continue to refer to Figure 1 As shown, in this embodiment, the membrane cutting assembly 6 is located inside the annulus 2. It includes a support base 61 disposed on the upper end of the base plate 1 and a first cylinder 62 disposed on the lower end of the base plate 1. A support block 63 is disposed on the support base 61, and a blade holder 64 is mounted on the support block 63. A blade 65 is clamped on one side of the blade holder 64. The output end of the first cylinder 62 is connected to the blade holder 64. The support block 63 can be made of Teflon (polytetrafluoroethylene, PTFE), which has an extremely low coefficient of friction and can reduce wear on the blade 65.

[0054] Specifically, the first cylinder 62 is used to lift the blade holder 64 to the upper end of the plastic wrap 41 before the last turn of plastic wrap 41 is wrapped around the spool, thereby driving the blade 65 to move to the upper end of the plastic wrap. At the same time, after the last turn of plastic wrap is wrapped around the spool, the blade holder 64 is driven to move down, thereby driving the blade 65 to move down to cut the plastic wrap 41.

[0055] It should be noted that after the cutting is completed, the next spool can be wound. At this time, as the blade 65 moves downward, it will squeeze the plastic wrap onto the support block 63, causing the end of the plastic wrap 41 wrapped around the next spool to be pressed between the blade holder 64 and the support block 63. After the second spool is wrapped with plastic wrap 41, the film cutting component 6 needs to perform a second cutting operation to cut the plastic wrap 41. Because the plastic wrap 41 is relatively thin, it easily adheres to the blade holder 64 or the support block 63. During the second cutting, when the blade holder 64 moves upward, the end of the plastic wrap cannot be actively pulled out from between the blade holder 64 and the support block 63. If the end of the plastic wrap 41 cannot be pulled out from between the blade holder 64 and the support block 63, after the second cutting is completed, the end of the plastic wrap wrapped around the second spool will still be pressed between the blade holder 64 and the support block 63, which will cause the second spool to be unable to be smoothly removed from the spool fixing component 3. Therefore, before the second cutting operation is performed by the film cutting assembly 6, the end of the plastic wrap 41 that was pressed during the first cutting needs to be pulled out from between the blade holder 64 and the support block 63.

[0056] In some preferred embodiments, a membrane lifting assembly 7 is also provided inside the ring 2 near the membrane cutting assembly 6, which includes a second cylinder 71 mounted on the base plate 1. The output end of the second cylinder 71 is connected to an optical axis clamp 72, and an optical axis 73 is mounted on the optical axis clamp 72.

[0057] In this embodiment, by setting up the film lifting assembly 7, after the first spool is wound, the blade 65 moves down to cut the plastic wrap 41, and the first spool is removed from the spool fixing assembly 3. Then, the second spool is placed, and the drive motor 52 starts the winding operation. At this time, one end of the plastic wrap is pressed on the blade holder 64 and the support block 63, and the other end is on the film roll assembly 4. The drive motor 52 drives the film roll assembly 4 to move around the second spool, thus winding the plastic wrap 41 onto the second spool. After winding at least one turn, the first cylinder 62 is driven to move upward to release the pressed end of the plastic wrap 41. Then, the second cylinder 71 is driven to move the optical shaft 73 upward to lift and pull out the pressed end of the plastic wrap 41. To avoid affecting the winding operation of the plastic wrap, the second cylinder 71 and the first cylinder 62 need to be quickly reset. The film roll assembly 4 continues to wind the second spool. The end of the pulled-out cling film 41 is pulled along by the subsequent cling film 41 and wound onto the second spool. After the second spool is wound, the first cylinder 62 repeats the cutting operation, and so on, to complete the automated film winding motion. Therefore, starting from the second spool, the first cylinder 62 needs to move upward twice within one spool winding cycle: once to loosen the pressed cling film and once to cut the cling film.

[0058] That is, by setting the film lifting component 7, only when the first spool is being wound does it need to be manually wound around the end of the cling film onto the spool. For subsequent spools, after the first spool is wound, the end of the cling film adheres to the support block 63. The film roll component 4 rotates around the spool fixing component 3, so that the cling film is wound and adheres to the second spool. Before the winding is completed, the optical axis 73 can lift and pull out the end of the cling film, so there is no need to manually wind the film or pull out the end of the cling film. Only the spool needs to be placed. Of course, in some other embodiments, an automatic spool picking and placing mechanism can also be set to achieve more automated operation.

[0059] In some embodiments, the first cylinder 62 and the second cylinder 71 are both biaxial cylinders, which can improve the stability of the movement process, reduce cylinder wobbling and deviation, and make the movement smoother and more accurate.

[0060] To further precisely control the position of the blade 65 as it moves down to cut the plastic wrap 41, a proximity switch 8 that contacts the ring 2 is also installed on the base plate 1. It is also understood that the wrapping equipment is equipped with a controller (not shown in the figure) that is signal-connected to the proximity switch 8. The controller is signal-connected to various electrical components in the equipment, such as the proximity switch 8, the first cylinder 62, and the second cylinder 71. When the film roll assembly 4 rotates into the detection range of the proximity switch 8, the proximity switch 8 can accurately sense its position and send a signal to the controller. The controller can then control the lifting and lowering of the first cylinder 62 and the second cylinder 71 to achieve precise cutting of the plastic wrap 41.

[0061] In summary, the design provided by this invention can significantly increase the efficiency of spool winding; it can improve the consistency, synchronization, and standardization of spool winding. Furthermore, the equipment has a simple structure, is easy to maintain and repair, and only requires belt replacement after wear.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and simple improvements made on the substantive content of the present utility model should be included within the protection scope of the present utility model.
