Description

Technical Field

[0001] This invention belongs to the technical field of equipment for aluminum foil production, and particularly relates to a conveying structure for an aluminum foil slitting machine. Background Technology

[0002] Aluminum foil paper is mainly composed of three layers: the aluminum foil layer, the adhesive layer, and the liner paper layer. Therefore, the slitting heads of slitting machines used in aluminum foil paper production tend to accumulate glue clumps after a period of use, a phenomenon not seen in ordinary paper slitting machines.

[0003] If the glue clump is not removed in time, the direct consequence is that the cut edges of the aluminum foil will easily become rough. Furthermore, aluminum foil debris will remain on the slitting blade, further exacerbating the roughness of the cut edges.

[0004] On the other hand, there is a difference in usage requirements between ordinary paper slitting machines and aluminum foil slitting machines. Ordinary paper does not have a multi-layered structure bonded by glue, so the curing degree of the adhesive layer does not need to be considered when slitting it. However, aluminum foil slitting machines generally have a hot air drying function, which allows the adhesive to cure as soon as possible.

[0005] For example, Chinese utility model patent with patent publication number CN211644054U and publication date of October 9, 2020 discloses a slitting machine for aluminum foil paper. Its structure includes a supporting base frame, a placement frame, a winding roller, a first upright frame, an upper pressure roller, a lower pressure roller, a second upright frame, a third upright frame, a mechanical meter counter, and a small drying fan.

[0006] The aluminum foil slitting machine in this utility model patent uses a small drying fan to blow hot air from the drying duct during operation, completing the drying operation on the upper surface of the aluminum foil to remove moisture from the aluminum foil, increase the dryness and bonding strength of the aluminum foil, and thus ensure the quality of subsequent aluminum foil production.

[0007] However, in actual use, this aluminum foil slitting machine still has at least the following two shortcomings, which are the technical problems that this invention aims to solve:

[0008] First, its drying air duct is only located above the aluminum foil, so the lower layer of aluminum foil cannot get a sufficient drying effect, which ultimately leads to the harmful problems of uneven drying and insufficient bonding strength inside the aluminum foil.

[0009] Secondly, it lacks the function of removing glue clumps from the slitting head, which requires operators to manually peel them off, which is very troublesome and dangerous.

[0010] Therefore, in summary, there is an urgent need for a new type of aluminum foil slitting machine with double-sided heating and glue removal function of the slitting head. Summary of the Invention

[0011] This invention provides a conveying structure for an aluminum foil slitting machine. By arranging a pair of conveying rollers, a post-slitting take-up roller, a double-layer hot air box unit, a lifting slitting blade unit, a hot air blower, a lifting frame unit, and a blow-off guide plate unit on the base plate, it is possible to: 1. Ensure sufficient hot air drying effect on both the upper and lower surfaces of the aluminum foil; 2. Lower the lifting slitting blade unit and the hot air blower together, while the double-layer hot air box unit switches from double-layer drying mode to blade head glue clump blowing mode, ensuring that the blade head glue clumps can be automatically blown off.

[0012] The technical solution adopted by the present invention to solve the above problems is: a conveying structure for an aluminum foil slitting machine, including a base plate, a pair of conveying rollers, and a slitting and winding roller, and further including a double-layer hot air box unit disposed on the base plate and located on the upper and lower sides of the aluminum foil, a lifting slitting blade unit disposed on the base plate and located between the double-layer hot air box unit and the slitting and winding roller, a hot air blower, a lifting frame unit disposed on the base plate and used to switch the double-layer drying working state and the blade glue ball blowing working state by adjusting the lifting of the hot air blower, and a blowing air guide plate unit disposed on the lifting frame unit and located on the lower side of the aluminum foil, wherein the hot air blower is disposed on the lifting frame unit.

[0013] A further preferred technical solution is that the double-layer hot air box unit includes a support column disposed on the base plate, an upper open box disposed on the support column and located below the aluminum foil, a tee pipe disposed on one end face of the upper open box and used to connect to the hot air blower, a lower open box disposed on the tee pipe and located above the aluminum foil, and a blow-off air inlet pipe disposed on one end face of the upper open box and selectively connected to the hot air blower along with the tee pipe.

[0014] A further preferred technical solution is that the lifting and slitting knife unit includes a lifting base plate and a vertical blade head disposed on the lifting base plate for slitting aluminum foil.

[0015] A further preferred technical solution is that the lifting and slitting blade unit further includes a slitting cylinder disposed on the base plate and used for mounting the lifting base plate.

[0016] A further preferred technical solution is that the lifting and slitting blade unit further includes an extension plate disposed on the lifting base plate and used to connect the lifting frame unit.

[0017] A further preferred technical solution is that the lifting frame unit includes a hot air blower cylinder disposed on the base plate, a lower plate disposed on the hot air blower cylinder and having the hot air blower disposed on its upper surface, which is used to seal the air inlet pipe for blowing off the aluminum foil during double-layer drying, and an upper plate disposed on the upper surface of the hot air blower, which is used to seal the three-way pipe when blowing off the glue clumps from the blade head.

[0018] A further preferred technical solution is that the lifting frame unit further includes a vertical height adjustment rod disposed on the upper surface of the lower plate and / or the lower surface of the upper plate, and used for mounting the hot air blower.

[0019] A further preferred technical solution is that the lifting frame unit also includes a guide rod disposed on the base plate and inserted into the lower plate and the upper plate.

[0020] A further preferred technical solution is that the blow-off air guide plate unit includes a horizontal connecting rod disposed on the hot air blower or the vertical height adjustment rod, and a single bending plate disposed on the horizontal connecting rod, with both sides inclined downwards, for guiding the airflow of the already lowered vertical cutter head to blow off the glue clump.

[0021] A further preferred technical solution is that the height of one side of the single-bending plate closest to the vertical cutter head is higher than the height of the other side. Attached Figure Description

Detailed Implementation

[0036] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0037] As attached Figure 1-9 As shown, a conveying structure for an aluminum foil slitting machine includes a base plate 11, a pair of conveying rollers 12, and a slitting and winding roller 13. It also includes a double-layer hot air box unit 1 disposed on the base plate 11 and located on the upper and lower sides of the aluminum foil a, a lifting slitting blade unit 2 disposed on the base plate 11 and located between the double-layer hot air box unit 1 and the slitting and winding roller 13, a hot air blower 3, a lifting frame unit 4 disposed on the base plate 11 and used to switch between the double-layer drying working state and the blade glue ball blowing working state by adjusting the lifting of the hot air blower 3, and a blowing guide plate unit 5 disposed on the lifting frame unit 4 and located on the lower side of the aluminum foil a. The hot air blower 3 is disposed on the lifting frame unit 4.

[0038] In this embodiment, the conveying structure plus the unwinding structure essentially constitutes a complete slitting machine. The paired conveying rollers 12 include one roller at the top and one at the bottom, and their operation can be either powered or unpowered. The post-slitting take-up rollers 13, however, must be powered. Furthermore, the number of post-slitting take-up rollers 13 is one more than the number of slitting blades. For example, if four slitting blades are used together to longitudinally slit aluminum foil, five rolls of narrower aluminum foil will be produced, requiring five post-slitting take-up rollers 13.

[0039] Furthermore, the upper half of the double-layer hot air box unit 1 blows hot air downwards and the lower half blows hot air upwards, ultimately ensuring that the aluminum foil is fully and thoroughly dried.

[0040] The hot air blower 3, together with the lifting frame unit 4, has two working heights, corresponding to the two working states of double-layer drying and blowing off the glue clumps from the blade. Ultimately, one air source can simultaneously perform two completely different functions: double-layer drying and blowing off the glue clumps from the blade, which is quite ingenious.

[0041] Finally, the air guide plate unit 5 for blowing off the glue clumps does not significantly affect the double-layer drying effect before the glue clump blowing off operation is activated. However, when the glue clump blowing off operation is activated, it can gather airflow and ensure that the glue clumps f are blown off quickly with a larger airflow speed.

[0042] It should be noted that the above-mentioned operation of blowing off the glue clump from the blade head is very rapid. At this time, the conveying structure does not need to be stopped. After the glue clump f falls off, the lifting and slitting blade unit 2, together with the hot air blower 3, can simply return to its original position. At this time, the aluminum foil needs to be temporarily cut at the relatively upper position of the lifting and slitting blade unit 2, but the time is very short and the amount of glue accumulated there is negligible.

[0043] The double-layer hot air box unit 1 includes a support column 101 disposed on the base plate 11, an upper opening box 102 disposed on the support column 101 and located below the aluminum foil a, a three-way pipe 103 disposed on one end face of the upper opening box 102 and used to connect to the hot air blower 3, a lower opening box 104 disposed on the three-way pipe 103 and located above the aluminum foil a, and a blow-off air inlet pipe 105 disposed on one end face of the upper opening box 102 and selectively connected to the hot air blower 3 along with the three-way pipe 103.

[0044] In this embodiment, the upper opening box 102 is at the bottom and the lower opening box 104 is at the top, ensuring that the hot air drying operation facing each other can fully and thoroughly cure the adhesive layer in the aluminum foil.

[0045] Furthermore, the vertical projections of the air inlet of the three-way pipe 103 and the air inlet of the blow-off air inlet pipe 105 overlap, ensuring that the hot air blower 3 can effectively connect to one of these two air inlets.

[0046] The lifting and slitting knife unit 2 includes a lifting base plate 201 and a vertical blade head 202 disposed on the lifting base plate 201 and used for slitting aluminum foil paper a.

[0047] In this embodiment, when the vertical blade 202 blows off the glue clump, its upper end is still higher than the aluminum foil a, ensuring that the blowing off of the glue clump does not affect the cutting operation of the aluminum foil, that is, the conveying structure does not need to be stopped.

[0048] All the vertical blades 202 are parallel to each other and the blades face the aluminum foil a. However, the vertical blades 202 do not necessarily need to be equidistant from each other. The distance between the blades is determined according to the actual size of the aluminum foil to be cut.

[0049] The lifting and slitting blade unit 2 also includes a slitting cylinder 203 disposed on the base plate 11 and used to install the lifting base plate 201.

[0050] In this embodiment, the first lifting method of the vertical cutter head 202 is to set up an independent cutting cylinder 203 to ensure that when the glue ball f accumulates a sufficient amount, its height can be sufficiently and appropriately lower than the aluminum foil paper a, so that the glue ball f can fall safely afterward.

[0051] The lifting and slitting blade unit 2 also includes an extension plate 204 disposed on the lifting base plate 201 and used to connect the lifting frame unit 4.

[0052] In this embodiment, the second lifting method of the vertical cutter head 202 is to use and link the cylinder of the lifting frame unit 4 to ensure that the low position of the glue blob f to be removed is sufficiently lower than the height of the aluminum foil a.

[0053] At this time, the extension plate 204 can fix the "slitting height" and "glue ball blowing height" of the lifting base plate 201 within a suitable range at the beginning of the size design of the conveying structure by its own tilt angle.

[0054] The lifting frame unit 4 includes a hot air blower cylinder 401 mounted on the base plate 11, a lower plate 402 mounted on the hot air blower cylinder 401 with the hot air blower 3 mounted on its upper surface and used to seal the air inlet pipe 105 for blowing off the aluminum foil during double-layer drying, and an upper plate 403 mounted on the upper surface of the hot air blower 3 and used to seal the three-way pipe 103 when blowing off the glue clumps from the blade.

[0055] In this embodiment, when the hot air blower 3 is connected to the three-way pipe 103, the lower plate 402 precisely blocks the air inlet pipe 105 for blowing off, ensuring that the hot air is only blown out at the upper opening box 102 and the lower opening box 104. In principle, the utilization rate of the hot air for drying aluminum foil is 100%.

[0056] When the hot air blower 3 is connected to the air inlet pipe 105 for blowing off, the upper plate 403 blocks the three-way pipe 103, ensuring that as much hot air as possible comes out of the upper opening box 102. At this time, this part of the hot air is guided downward by the air guide plate unit 5 for blowing off, and the glue ball blowing off operation can be completed.

[0057] However, it should be noted that at this time, a relatively small amount of hot air will still be blown downwards from the lower opening box 104. The reason for this working mode is as follows:

[0058] First, at this time, the conveying structure is still performing aluminum foil cutting, so a double-layer drying effect is still required. Therefore, the lower opening box 104 cannot be completely closed.

[0059] Secondly, the air inlet pipe 105 for blowing off is directly and separately installed on the upper open box 102. Therefore, the upper open box 102 will release a relatively large amount of hot air, while the lower open box 104 will release a relatively small amount of hot air. The former is then collected by the air guide plate unit 5 for blowing off, and its airflow speed is sufficient. Therefore, it is not necessary to completely block the three-way pipe 103, but only to block the air inlet of the three-way pipe 103.

[0060] The lifting frame unit 4 also includes a vertical height adjustment rod 404 disposed on the upper surface of the lower plate 402 and / or the lower surface of the upper plate 403, and used for mounting the hot air blower 3.

[0061] In this embodiment, the vertical height adjustment rod 404 is used to adjust the relative height between the upper plate 403, the hot air blower 3 and the lower plate 402, so as to ensure that the selective sealing function of the upper plate 403 and the lower plate 402 is effective.

[0062] The lifting frame unit 4 also includes a guide rod 405 disposed on the base plate 11 and inserted into the lower plate 402 and the upper plate 403.

[0063] In this embodiment, since the load weight on the cylinder 401 of the hot air blower is relatively large, two or four guide rods 405 are provided to ensure that the lifting frame unit 4 can only move straight up and down, avoiding harmful lateral deviation.

[0064] At this point, corresponding guide holes need to be made on the lower plate 402 and the upper plate 403.

[0065] The blow-off air guide plate unit 5 includes a horizontal connecting rod 501 mounted on the hot air blower 3 or the vertical height adjustment rod 404, and a single bending plate 502 mounted on the horizontal connecting rod 501, with both sides inclined downwards, for guiding the airflow of the already lowered vertical cutter head 202 to blow off the glue clump.

[0066] In this embodiment, if the transverse connecting rod 501 is provided on the hot air blower 3, it is indirectly provided on the lifting frame unit 4.

[0067] There are two transverse connecting rods 501, located on both sides of the three-way pipe 103, to ensure that the three-way pipe 103 will not be bumped or damaged.

[0068] In addition, the vertical cross-sectional shape of the single-bending plate 502 is similar to an "L" shape. One side of the plate is used to block the hot air, and the other side is used to tilt downwards to guide and collect the hot air, ensuring that the glue clump f can be blown downwards quickly and safely.

[0069] Of course, end baffles can also be provided on both sides of the single-bending plate 502 to ensure that the above-mentioned hot air collection effect is more complete.

[0070] The height of one side of the single-bending plate 502 closest to the vertical cutter head 202 is higher than the height of the other side.

[0071] In this embodiment, the relatively high waiting height of the single bending plate 502 is just enough to ensure that it will not touch the aluminum foil paper a, while its relatively low working height means that its lower side directly abuts the upper surface of the upper opening box 102. At this time, the higher side can collect and guide hot air to ensure that the glue ball blowing operation can be carried out quickly and efficiently.

[0072] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of the present invention. These are non-inventive modifications and are protected by patent law as long as they fall within the scope of the claims of the present invention.
