[0002] At present, with the development of society, the use of aluminum foil is becoming more and more extensive in people's daily life. Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, medicines, photographic plates, household daily necessities, etc., and is usually used as their packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, airtight, light-shielding, abrasion-resistant, fragrance-preserving, non-toxic and tasteless, but also because of its elegant silver-white luster, it is easy to process beautiful patterns and designs of various colors, so it is more likely to be favored by people.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, an adjustable aluminum foil processing device is provided, the device comprising:

[0033] The main frame 1 comprises a mounting seat 101 arranged on the main frame 1, a fixing frame 102 is fixedly mounted on the surface of the mounting seat 101, and a guide roller 103 is rotatably connected to the surface of the fixing frame 102;

[0034] Cutting mechanism 2: includes an aluminum foil strip 201 in contact with the surface of the guide roller 103, a plurality of cutting knives 202 mounted on the fixing frame 102, and two pressing rollers 203 corresponding to each cutting knife 202, and a connecting frame 204 is rotatably mounted on the surface of the pressing roller 203;

[0035] Distance adjustment mechanism 3: used to drive the cutting knife 202 to move horizontally to adjust the distance;

[0036] Elastic mechanism 4: used to drive the pressing roller 203 to press the part of the aluminum foil strip 201;

[0037] Driving mechanism 7: used to drive the cutting knife 202 to contact the aluminum foil strip 201.

[0038] In practical application of the embodiment of the present invention, when the aluminum foil strip 201 is cut, Figure 2 and Figure 3 As shown, at this time, the cutting knife 202 is driven to move to the left and right ends respectively through the action of the distance adjustment mechanism 3. It should be noted here that the cutting knife 202 located in the middle is always kept in the middle position when the device is running, that is, taking the middle position as a reference, the cutting knives 202 on both sides move to the two ends respectively, and under the action of the distance adjustment mechanism 3, the movement distance of the cutting knife 202 close to the middle position is half of the movement distance of the adjacent moving cutting knife 202, thereby ensuring that the distance between adjacent cutting knives 202 is always consistent, so that the cutting width is consistent, ensuring that there is no difference in the width of the cut aluminum foil strip 201, and improving the efficiency of adjusting the width of the aluminum foil strip 201. When the distance adjustment is completed, as shown in FIG. Figure 2 As shown, from Figure 2 From the front view direction, at this time, the cutting knife 202 is driven to move downward under the action of the driving mechanism 7, and the downward movement of the cutting knife 202 contacts the aluminum foil strip 201. At the same time, the pressing roller 203 is driven to squeeze the surface of the aluminum foil strip 201 through the action of the elastic mechanism 4. At this time, the cutting action of the cutting knife 202 on the aluminum foil strip 201 is realized through the winding action of the aluminum foil strip 201, so as to achieve the purpose of automatically and equidistantly cutting the aluminum foil strip 201. At the same time, the local squeezing action of the pressing roller 203 is utilized to avoid the lateral deviation of the aluminum foil strip 201 during the winding cutting, resulting in cutting burrs, which affects the cutting quality of the aluminum foil strip 201. At the same time, the driving mechanism 7 drives the distance adjustment mechanism 3 to move upward, and then the distance adjustment mechanism 3 enables the cutting knife 202 to automatically switch to a new cutting knife 202 after completing a certain period of cutting, so as to ensure the cutting quality of the aluminum foil strip 201.

[0039] like Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, as a preferred embodiment of the present invention, the distance adjustment mechanism 3 includes a rotating column 301 installed on the fixed frame 102, and two first spiral slideways 307 and second spiral slideways 308 with opposite directions are fixedly installed on the surface of the rotating column 301, and the surface of each first spiral slideway 307 and the second spiral slideway 308 is in contact with a moving block 302, and the surface of each moving block 302 is in contact with the distance adjustment groove 304, and the distance adjustment groove 304 is arranged inside the slide groove cylinder 303, and the rotating column 301 passes through the slide groove cylinder 303 and is rotatably connected to the slide groove cylinder 303, and a moving cylinder 305 is fixedly installed on the surface of the moving block 302, and another moving cylinder 305 is fixedly installed on the surface of the slide groove cylinder 303, and the moving cylinders 305 are connected by connecting springs, and the surface of each moving cylinder 305 is rotatably connected with a tool rotating cylinder 306, and a plurality of cutting knives 202 are fixedly installed on the surface of the tool rotating cylinder 306.

[0040] In actual application of the embodiment of the present invention, when the cutting blade 202 is adjusted, Figure 2 and Figure 3 As shown, at this time, the rotating column 301 starts to rotate, as shown in FIG. Figure 7 and Figure 8 As shown, the rotation of the rotating column 301 drives the first spiral slide 307 and the second spiral slide 308 to rotate synchronously, as shown in FIG. Figure 2 As shown, at this time, the first spiral slide 307 and the second spiral slide 308 push the moving block 302 to move to the right. Since the moving cylinder 305 in the middle position is fixed on the slide groove cylinder 303, and the first spiral slide 307 and the second spiral slide 308 at the symmetrical end have opposite spiral directions, the moving block 302 at the symmetrical end moves to the left. Since the moving block 302 is limited by the distance adjustment groove 304, the moving block 302 is driven by the first spiral slide 307 and the second spiral slide 308. The block 302 moves away from the middle moving cylinder 305, and then the moving block 302 drives the cutting knife 202 to move through the moving cylinder 305 and the tool rotating cylinder 306. Since the arc pitch of the second spiral slide 308 is twice that of the first spiral slide 307, the movement distance of the moving block 302 coordinated with the first spiral slide 307 is half of the movement distance of the moving block 302 coordinated with the second spiral slide 308, thereby ensuring the consistency of width adjustment and realizing equidistant cutting of the aluminum foil strip 201.

[0041] like Figure 2 and Figure 3 As shown, as another preferred embodiment of the present invention, the elastic mechanism 4 includes a sliding rod 401 fixedly connected to the surface of the connecting frame 204, the sliding rod 401 passes through the tool cylinder 306 and is slidably connected to the tool cylinder 306, and the connecting frame 204 is connected to the surface of the tool cylinder 306 through a compression spring 402.

[0042] In practical application, the embodiment of the present invention is as follows: Figure 3 As shown, when the cutting knife 202 is driven downward by the driving mechanism 7, the pressing roller 203 and the connecting frame 204 are simultaneously driven downward. At this time, after the pressing roller 203 contacts the aluminum foil strip 201, as shown in FIG. Figure 2 As shown, the sliding rod 401 is driven upward by the extrusion of the reaction force, and the compression spring 402 is compressed at the same time, thereby ensuring that when the aluminum foil strip 201 is wound and cut, the cutting position will not shift laterally to cause uneven cutting and burrs.

[0043] like Figure 4 As shown, as another preferred embodiment of the present invention, the device also includes a rotating mechanism 5, the rotating mechanism 5 includes a rotating motor 501 installed on the fixed frame 102, the output end of the rotating motor 501 is fixedly installed with a rotating bevel gear 502, the rotating bevel gear 502 is meshed with the driven bevel gear 503, and the surface of the driven bevel gear 503 is fixedly installed with a rotating column 301.

[0044] In actual application of the embodiment of the present invention, when the cutting blade 202 is adjusted, Figure 4 As shown, at this time, the rotating motor 501 starts to run, and the operation of the rotating motor 501 drives the rotating bevel gear 502 to rotate, and then drives the rotating column 301 to rotate through the gear meshing action, so that the equidistant adjustment is completed through the action of the distance adjustment mechanism 3.

[0045] like Figure 2 , Figure 5 and Figure 6 As shown, as another preferred embodiment of the present invention, the device also includes a tool changing mechanism 6, the tool changing mechanism 6 includes two tool changing ratchets 601 rotatably mounted on the slide groove cylinder 303, each tool changing ratchet 601 is meshed with a tool changing rack 602, the tool changing rack 602 is fixedly mounted on the surface of the fixed frame 102, four through rods 603 are fixedly mounted on the surface of the tool changing ratchet 601, and the through rods 603 penetrate the tool rotating cylinder 306 and are slidably connected to the tool rotating cylinder 306, and the other end of the through rod 603 is fixedly connected to another tool changing ratchet 601.

[0046] In practical application of the embodiment of the present invention, when the tool is switched after working for a long time, such as Figure 2 As shown, from Figure 2 From the front view direction, the driving mechanism 7 drives the chute cylinder 303 to move upward, and the movement of the chute cylinder 303 drives the tool changing ratchet 601 to move upward synchronously. At this time, under the action of the tool changing rack 602, the tool changing ratchet 601 is driven to rotate, such as Figure 6As shown, the rotation of the knife-changing ratchet 601 drives the tool drum 306 to rotate through the action of the through rod 603, and then drives the cutting knife 202 to rotate. At this time, the new cutting knife 202 set on the tool drum 306 moves to the position of the cutting knife 202 to be replaced, and under the action of the driving mechanism 7, it descends again to contact and cut the aluminum foil strip 201. It should be noted here that due to the ratchet characteristics of the knife-changing ratchet 601 itself, it will not rotate when moving downward under the action of the driving mechanism 7. At the same time, the knife-changing ratchet 601 will not rotate immediately when rising, so as to avoid the aluminum foil strip 201 being scraped and affecting the subsequent cutting quality of the aluminum foil strip 201.

[0047] like Figure 2 As shown, as another preferred embodiment of the present invention, the driving mechanism 7 includes a driving motor 701 fixedly mounted on the fixed frame 102, the output end of the driving motor 701 passes through the fixed frame 102 and is rotatably connected to the fixed frame 102, a rotating screw 702 is fixedly mounted on the output end of the driving motor 701, the rotating screw 702 and the moving slider 703 form a spiral pair transmission, a rotating motor 501 is fixedly mounted on the moving slider 703, the output end of the rotating motor 501 passes through the moving slider 703 and is rotatably connected to the moving slider 703, and a slide groove cylinder 303 is fixedly mounted on the inner wall of the moving slider 703.

[0048] In actual application of the embodiment of the present invention, when replacing a new cutting blade 202, as shown in FIG. Figure 2 As shown, at this time, the driving motor 701 starts to move, and the operation of the driving motor 701 drives the rotating screw 702 to rotate, and then drives the moving slider 703 to move upward through the action of the spiral pair transmission, and then drives the slide groove cylinder 303 to move upward. The movement of the slide groove cylinder 303 drives the cutting knife 202 to be replaced through the action of the knife changing mechanism 6. After the replacement is completed, the driving motor 701 runs in the reverse direction, driving the new cutting knife 202 to descend again to contact and cut with the aluminum foil strip 201 to ensure the cutting quality.

[0049] like Figure 2 As shown, as another preferred embodiment of the present invention, a rubber soft sleeve is sleeved on the circumferential surface of the pressing roller 203 .

[0050] In actual application, the rubber sleeve provided on the pressing roller 203 ensures that the pressing roller 203 will not scratch the surface of the aluminum foil strip 201 when squeezing the aluminum foil strip 201, thereby avoiding cutting quality problems of the aluminum foil strip 201.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
