Description

Technical Field

[0001] This invention relates to the field of aluminum foil manufacturing technology, and in particular to an adjustable aluminum foil processing apparatus. Background Technology

[0002] With the development of society, aluminum foil is being used more and more widely in people's daily lives. 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 that not only has the advantages of moisture-proof, airtight, light-blocking, wear-resistant, aroma-preserving, non-toxic and odorless, but also has an elegant silver-white luster and is easy to process into beautiful patterns and designs of various colors, making it more popular with people.

[0003] Currently, in the production process of aluminum foil, the width of the aluminum foil needs to be confirmed before winding. The winding width of the aluminum foil is adjusted by using a cutting blade. Conventional cutting equipment adjusts the spacing of the cutting blades semi-automatically. At this time, the adjustment is based on the cutting blade at one end, which requires confirming the distance of movement of each cutting blade. This makes the adjustment process extremely complicated and cumbersome, greatly reducing production efficiency.

[0004] Based on this, the present invention designs an adjustable aluminum foil processing device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable aluminum foil processing device, which aims to solve the technical problems existing in the prior art mentioned in the background.

[0006] The present invention is implemented as follows: an adjustable aluminum foil processing device, the device comprising:

[0007] Main frame: includes a mounting base on the main frame, a fixed frame is fixedly mounted on the surface of the mounting base, and a guide roller is rotatably connected to the surface of the fixed frame;

[0008] Cutting mechanism: includes an aluminum foil strip in contact with the surface of the guide roller, multiple cutting blades mounted on a fixed frame, and two pressing rollers corresponding to each cutting blade, with connecting frames rotatably mounted on the surface of the pressing rollers;

[0009] Adjustment mechanism: used to drive the cutting blade to move laterally and adjust the spacing;

[0010] Elastic mechanism: used to drive the pressing rollers to locally press the aluminum foil strip;

[0011] Drive mechanism: Used to drive the cutting blade into contact with the aluminum foil strip.

[0012] Furthermore, the adjusting mechanism includes a rotating column mounted on a fixed frame. Two first and second helical slides with opposite directions are fixedly mounted on the surface of the rotating column. The surface of each first and second helical slide is in contact with a moving block. The surface of each moving block is in contact with an adjusting groove. The adjusting groove is opened inside the slide cylinder. The rotating column passes through the slide cylinder and is rotatably connected to the slide cylinder. A moving cylinder is fixedly mounted on the surface of the moving block. Another moving cylinder is fixedly mounted on the surface of the slide cylinder. The moving cylinders are connected to each other by a connecting spring. A tool rotating cylinder is rotatably connected to the surface of each moving cylinder. Multiple cutting blades are fixedly mounted on the surface of the tool rotating cylinder.

[0013] Furthermore, the elastic mechanism includes a sliding rod fixedly connected to the surface of the connecting frame, the sliding rod passing through the tool cylinder and slidably connected to the tool cylinder, and the connecting frame being connected to the surface of the tool cylinder via a compression spring.

[0014] Furthermore, the device also includes a rotating mechanism, which includes a rotating motor mounted on a fixed frame. A rotating bevel gear is fixedly mounted on the output end of the rotating motor. The rotating bevel gear meshes with a driven bevel gear, and a rotating column is fixedly mounted on the surface of the driven bevel gear.

[0015] Furthermore, the device also includes a tool changing mechanism, which includes two tool changing ratchet teeth rotatably mounted on the slide tube. Each tool changing ratchet tooth meshes with a tool changing rack. The tool changing rack is fixedly mounted on the surface of the fixed frame. Four through rods are fixedly mounted on the surface of the tool changing ratchet teeth. The through rods pass through the tool rotating cylinder and are slidably connected to the tool rotating cylinder. The other end of the through rod is fixedly connected to another tool changing ratchet tooth.

[0016] Furthermore, the driving mechanism includes a drive motor fixedly mounted on a fixed frame, the output end of the drive motor passing through the fixed frame and rotatably connected to the fixed frame, a rotating lead screw fixedly mounted on the output end of the drive motor, the rotating lead screw and the movable slider forming a helical pair transmission, a rotating motor fixedly mounted on the movable slider, the output end of the rotating motor passing through the movable slider and rotatably connected to the movable slider, and a sliding groove cylinder fixedly mounted on the inner wall of the movable slider.

[0017] Furthermore, a rubber sleeve is fitted on the circumferential surface of the pressing roller.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The present invention ensures that the cutting blade located in the middle always remains in the middle position during the operation of the device. That is, with the middle position as the reference, the cutting blades on both sides move to both ends respectively. Under the action of the distance adjustment mechanism, the distance of the cutting blade closer to the middle position is half the distance of the adjacent moving cutting blade, thereby ensuring that the distance between adjacent cutting blades is always consistent, so that the cutting width is consistent and the width of the cut aluminum foil strip is not different, thus improving the efficiency of aluminum foil strip width adjustment.

[0020] 2. This invention utilizes the localized squeezing action of the pressing rollers to prevent lateral displacement of the aluminum foil strip during winding and cutting, which would cause cutting burrs and affect the cutting quality of the aluminum foil strip. At the same time, the driving mechanism drives the adjusting mechanism to move upward, and the adjusting mechanism enables the cutting blade to automatically switch to a new cutting blade after a certain period of cutting, thus ensuring the cutting quality of the aluminum foil strip.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

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

[0033] Main frame 1: includes a mounting base 101 provided on the main frame 1, a fixing frame 102 fixedly mounted on the surface of the mounting base 101, and a guide roller 103 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 blades 202 mounted on the fixed frame 102, and two pressing rollers 203 corresponding to each cutting blade 202. A connecting frame 204 is rotatably mounted on the surface of the pressing rollers 203.

[0035] Adjustment mechanism 3: used to drive the cutting blade 202 to move laterally and adjust the spacing;

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

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

[0038] In practical applications, when cutting aluminum foil strip 201, as in the embodiments of the present invention... Figure 2 and Figure 3 As shown, the adjusting mechanism 3 drives the cutting blades 202 to move to the left and right ends respectively. It should be noted that the middle cutting blade 202 remains in the center position throughout the device's operation. That is, with the center position as the reference, the cutting blades 202 on both sides move to opposite ends. Under the action of the adjusting mechanism 3, the distance the cutting blade 202 closest to the center moves is half the distance of the adjacent moving cutting blades 202, thus ensuring that the spacing between adjacent cutting blades 202 remains consistent, resulting in a consistent cutting width. This ensures that the width of the cut aluminum foil strip 201 will not differ, improving the efficiency of aluminum foil strip 201 width adjustment. After the spacing adjustment is completed, as shown... Figure 2 As shown, from Figure 2 Looking from the front, the cutting blade 202 moves downward under the action of the drive mechanism 7. The downward movement of the cutting blade 202 contacts the aluminum foil strip 201. At the same time, the pressing roller 203 is pressed against the surface of the aluminum foil strip 201 by the action of the elastic mechanism 4. At this time, the cutting blade 202 cuts the aluminum foil strip 201 by the winding action of the aluminum foil strip 201, thereby achieving the purpose of automatic equidistant cutting of the aluminum foil strip 201. At the same time, the local pressing action of the pressing roller 203 is used to avoid the lateral displacement of the aluminum foil strip 201 during winding and cutting, which would cause cutting burrs and affect the cutting quality of the aluminum foil strip 201. At the same time, the driving mechanism 7 drives the adjusting mechanism 3 to move upward, and the adjusting mechanism 3 enables the cutting blade 202 to automatically switch to a new cutting blade 202 after 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 in the preferred embodiment of the present invention, the adjusting mechanism 3 includes a rotating column 301 mounted on a fixed frame 102. Two first spiral slides 307 and second spiral slides 308 with opposite directions are fixedly mounted on the surface of the rotating column 301. The surface of each first spiral slide 307 and second spiral slide 308 is in contact with a moving block 302. The surface of each moving block 302 is in contact with an adjusting groove 304. The adjusting groove 304 is opened inside the sliding cylinder 303. The rotating column 301 passes through the sliding cylinder 303 and is rotatably connected to the sliding cylinder 303. A moving cylinder 305 is fixedly mounted on the surface of the moving block 302. Another moving cylinder 305 is fixedly mounted on the surface of the sliding cylinder 303. The moving cylinders 305 are connected to each other by a connecting spring. A tool rotating cylinder 306 is rotatably connected to the surface of each moving cylinder 305. A plurality of cutting blades 202 are fixedly mounted on the surface of the tool rotating cylinder 306.

[0040] In practical applications, when adjusting the distance of the cutting blade 202, as in the embodiments of the present invention... Figure 2 and Figure 3 As shown, at this time, the rotating column 301 begins to rotate, as... 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... Figure 2 As shown, at this time, the moving block 302 is pushed to the right by the first spiral slide 307 and the second spiral slide 308. Since the moving cylinder 305 in the middle position is fixed on the slide groove cylinder 303, and the spiral directions of the first spiral slide 307 and the second spiral slide 308 at the symmetrical ends are opposite, the moving block 302 at the symmetrical ends moves to the left. Since the moving block 302 is limited by the adjusting groove 304, the moving block 302 is driven to move by the pushing action of the first spiral slide 307 and the second spiral slide 308. Block 302 moves away from the central moving cylinder 305, and then the moving block 302 drives the cutting blade 202 to move through the moving cylinder 305 and the cutting tool rotating cylinder 306. Since the arc pitch of the second spiral slide 308 is twice that of the first spiral slide 307, the moving distance of the moving block 302 cooperating with the first spiral slide 307 is half the moving distance of the moving block 302 cooperating with the second spiral slide 308, thereby ensuring the consistency of width adjustment and realizing the equidistant cutting of the aluminum foil strip 201.

[0041] like Figure 2 and Figure 3 As shown, in 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. The connecting frame 204 is connected to the surface of the tool cylinder 306 through a compression spring 402.

[0042] In practical applications, the embodiments of the present invention, such as Figure 3 As shown, when the cutting blade 202 moves downward under the action of the drive mechanism 7, the pressing roller 203 and the connecting frame 204 move downward simultaneously. At this time, after the pressing roller 203 contacts the aluminum foil strip 201, as... Figure 2 As shown, under the pressure of the reaction force, the sliding rod 401 moves upward, while the compression spring 402 is compressed, thereby ensuring that the cutting position will not shift laterally when the aluminum foil strip 201 is wound and cut, resulting in uneven cutting and burrs.

[0043] like Figure 4 As shown, in another preferred embodiment of the present invention, the device further includes a rotating mechanism 5, which includes a rotating motor 501 mounted on a fixed frame 102. A rotating bevel gear 502 is fixedly mounted on the output end of the rotating motor 501. The rotating bevel gear 502 meshes with a driven bevel gear 503. A rotating column 301 is fixedly mounted on the surface of the driven bevel gear 503.

[0044] In practical applications, when adjusting the distance of the cutting blade 202, as in the embodiments of the present invention... Figure 4 As shown, the rotating motor 501 starts running at this time. The operation of the rotating motor 501 drives the rotating bevel gear 502 to rotate, which in turn drives the rotating column 301 to rotate through the gear meshing action, thereby completing the equidistant adjustment through the action of the adjusting mechanism 3.

[0045] like Figure 2 , Figure 5 and Figure 6 As shown, in another preferred embodiment of the present invention, the device further includes a tool changing mechanism 6. The tool changing mechanism 6 includes two tool changing ratchet teeth 601 rotatably mounted on the slide groove cylinder 303. Each tool changing ratchet tooth 601 meshes with a tool changing rack 602. The tool changing rack 602 is fixedly mounted on the surface of the fixing frame 102. Four through rods 603 are fixedly mounted on the surface of the tool changing ratchet tooth 601. The through rods 603 pass through the tool rotating cylinder 306 and are slidably connected to the tool rotating cylinder 306. The other end of the through rod 603 is fixedly connected to another tool changing ratchet tooth 601.

[0046] In practical applications, when switching tools after a long period of operation, such as... Figure 2 As shown, from Figure 2 Looking from the front direction, the drive mechanism 7 drives the slide cylinder 303 to move upward. The movement of the slide 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 rotates. Figure 6As shown, the rotation of the tool changing ratchet 601 drives the tool drum 306 to rotate through the through rod 603, which in turn drives the cutting blade 202 to rotate. At this time, the new cutting blade 202 set on the tool drum 306 moves to the position of the cutting blade 202 to be replaced, and then descends again under the action of the drive mechanism 7 to contact and cut the aluminum foil strip 201. It should be noted that due to the ratchet characteristics of the tool changing ratchet 601 itself, it will not rotate when it moves downward under the action of the drive mechanism 7, and it will not rotate immediately when it rises, 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, in 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 lead screw 702 is fixedly mounted on the output end of the driving motor 701. The rotating lead screw 702 and the movable slider 703 form a helical pair transmission. A rotating motor 501 is fixedly mounted on the movable slider 703. The output end of the rotating motor 501 passes through the movable slider 703 and is rotatably connected to the movable slider 703. A sliding groove cylinder 303 is fixedly mounted on the inner wall of the movable slider 703.

[0048] In practical applications, when replacing the cutting blade 202, as in the embodiments of the present invention... Figure 2 As shown, at this time, the drive motor 701 starts to move. The operation of the drive motor 701 drives the rotating lead screw 702 to rotate, which in turn drives the moving slider 703 to move upward through the action of the screw pair transmission, which in turn drives the sliding groove cylinder 303 to move upward. The movement of the sliding groove cylinder 303 drives the cutting blade 202 to be replaced through the action of the blade changing mechanism 6. After the replacement is completed, the drive motor 701 runs in reverse, driving the new cutting blade 202 to descend again and contact the aluminum foil strip 201 for cutting, ensuring the cutting quality.

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

[0050] In practical applications, the rubber sleeve on the pressing roller 203 ensures that the pressing roller 203 will not scratch the surface of the aluminum foil strip 201 when it is pressing the aluminum foil strip 201, thereby avoiding cutting quality problems of the aluminum foil strip 201.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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 embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
