Description

Technical Field

[0001] This invention relates to the field of waste collection technology, specifically to a composite film die-cutting waste collection device. Background Technology

[0002] Composite film is a multi-layered structural material made by combining two or more films of different materials (such as plastic film, aluminum foil, paper, non-woven fabric, etc.) through a composite process (dry lamination, wet lamination, extrusion lamination, hot pressing lamination, etc.). Composite film die-cutting is a processing technology for composite film. Die-cutting waste collection usually refers to the collection of waste material from die-cutting by sticking it with tape, and then the waste collection tube rewinds the collection tape to complete the collection of waste material.

[0003] In existing waste material collection methods, to avoid affecting the continued conveying of the composite film after die-cutting, the collection and winding rollers are usually located below the die-cutting frame. The collection tape is wound up at the bottom of the frame, which means that when disassembling the collected waste material or replacing the waste material collection cylinder, it is impossible to operate outside the frame. Usually, the operator has to bend down and reach under the frame, which not only restricts operation but also makes the alignment and adjustment during replacement difficult and time-consuming, which is not conducive to the rapid replacement of the waste material collection cylinder. In addition, it is easy to bump into things during operation, resulting in a low safety factor. Summary of the Invention

[0004] This invention provides a composite film die-cutting waste collection device, which aims to solve the problem in related technologies where the collection and winding roller is usually located below the die-cutting frame, making it impossible to operate outside the frame when disassembling the collected waste or replacing the waste collection cylinder.

[0005] The composite film die-cutting waste collection device of the present invention includes a frame and a take-up roller. The take-up roller is disposed at the bottom of the frame. A circular cavity is coaxially formed inside the take-up roller, and an axial groove is formed on the side wall of the take-up roller.

[0006] A connecting frame is slidably fitted inside the axial groove. An outer cylinder sleeved on the outside of the take-up roller is fixed on the connecting frame. An inner cylinder coaxially arranged with the circular cavity is also rotatably fitted inside the connecting frame. The inner cylinder can slide with the connecting frame in the circular cavity and rotate inside the connecting frame when it is close to the end of the take-up roller.

[0007] Both sides of the outer cylinder are equipped with push rods located in the axial grooves, which can extend or retract from the axial grooves as the inner cylinder rotates, and can also move closer to or away from the outer cylinder as the inner cylinder rotates.

A sliding shaft is fixedly installed on the inner ring. An inner magnet is fixedly installed on the inner ring, and an outer magnet is fixedly installed on the outer ring. The inner magnet and the outer magnet attract each other.

[0013] Preferably, a calibration disk is fixedly installed on the outer ring of each of the two ring sleeves, and the two calibration disks are located at both ends of the outer cylinder. An arc-shaped groove is opened on each of the two calibration disks, and the ends of the push rods on both sides of the outer cylinder are slidably assembled in the arc-shaped grooves of the two calibration disks.

[0014] Preferably, the outer cylinder has a positioning groove that communicates with the axial groove inside, the positioning plate is slidably assembled in the positioning groove, the inner cylinder is coaxially provided with an external threaded cylinder, the external threaded cylinder is threadedly connected with a threaded sleeve, the threaded sleeve is rotatably assembled with a connecting rod, and the end of the connecting rod away from the threaded sleeve is rotatably assembled on the positioning plate.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1 to 7 As shown, the composite film die-cutting waste collection device of the present invention includes a frame 10, a take-up roller 20, a support cylinder 30, a calibration component 40, a transmission mechanism 50, a positioning mechanism 60, and a drive mechanism 70. The take-up roller 20 is disposed below the frame 10, and the support cylinder 30 is disposed on the take-up roller 20 for mounting the waste collection cylinder. Then, the collection tape is wound up under the drive of the take-up roller 20. Two sets of calibration components 40 are symmetrically distributed on both sides of the support cylinder 30 for calibrating the position of the waste collection cylinder to the middle of the support cylinder 30. Then, the positioning mechanism 60 fixes the waste collection cylinder. The drive mechanism 70 is disposed inside the take-up roller 20 and can drive the transmission mechanism 50 to operate the calibration component 40 when the support cylinder 30 moves, and at the same time drive the positioning mechanism 60 to operate, thereby completing the calibration and fixing of the position of the waste collection cylinder.

[0030] refer to Figure 1 and Figure 2 A vertical plate 11 is fixedly installed at the bottom of the frame 10, and a take-up roller 20 is rotatably mounted on the vertical plate 11. A die-cutting roller 12 is provided at the top of the frame 10 for die-cutting the composite film. A guide roller 13 is provided on one side of the die-cutting roller 12 for guiding and supporting the collection tape.

[0031] The take-up roller 20 has a circular cavity 21 coaxially formed inside, and an axial groove 22 is formed on the side wall of the take-up roller 20 along its axial direction, connecting the circular cavity 21 to the outside of the take-up roller 20. There are multiple axial grooves 22, which are evenly distributed in a ring on the take-up roller 20.

[0032] refer to Figure 3 , Figure 5 as well as Figure 6 The support cylinder 30 includes an outer cylinder 31, a connecting frame 32, and an inner cylinder 33. The outer cylinder 31 is coaxially sleeved on the outside of the take-up roller 20 to support the waste collection cylinder. The connecting frame 32 is located inside the circular cavity 21, and the end of the connecting frame 32 is slidably assembled in the axial groove 22 and fixed to the outer cylinder 31. The inner cylinder 33 is rotatably assembled in the connecting frame 32, so that the support cylinder 30 can slide on the take-up roller 20. The side wall of the outer cylinder 31 is provided with multiple positioning grooves 311, and the multiple positioning grooves 311 are connected to the multiple axial grooves 22 one by one to facilitate the installation of the positioning mechanism 60.

[0033] refer to Figure 5 and Figure 7Both sets of calibration components 40 include a calibration disk 41, an arc-shaped groove 42, and a push rod 43. The calibration disk 41 is rotatably mounted on the end of the inner cylinder 33. The arc-shaped groove 42 is opened on the calibration disk 41. The bottom end of the push rod 43 is slidably mounted in the arc-shaped groove 42. The top end of the push rod 43 is set in the axial groove 22. The push rods 43 of the two calibration components 40 are located on both sides of the outer cylinder 31. They can rise and fall in the axial groove 22 under the rotation of the arc-shaped groove 42, so that their ends protrude from the axial groove 22. Then, when the calibration disk 41 moves, it pushes the waste collection tube to move towards the middle of the outer cylinder 31. The push rods 43 of the two sets of calibration components 40 can clamp the waste collection tube. A roller is provided on the side of the push rod 43 near the outer cylinder 31 so that the push rod 43 does not affect its movement in the radial direction of the outer cylinder 31 when clamping the waste collection tube.

[0034] refer to Figure 4 and Figure 7 The transmission mechanism 50 includes a transmission cylinder 51, a ring sleeve 52, and a sliding shaft 53. The transmission cylinder 51 is coaxially fixed to the outside of the inner cylinder 33. Both ends of the transmission cylinder 51 are provided with opposing spiral guide grooves 511. There are two ring sleeves 52, both of which are sleeved on the outside of the transmission cylinder 51, and the two ring sleeves 52 are respectively fixed to two calibration discs 41. There are two sliding shafts 53, which are respectively slidably assembled inside the two guide grooves 511, and the two sliding shafts 53 are respectively fixed to the two ring sleeves 52. When the transmission cylinder 51 rotates with the inner cylinder 33, it can push the sliding shafts 53 to rotate the ring sleeves 52, thereby driving the calibration discs 41 to rotate. When the ring sleeves 52 are restricted from rotating, the continuously rotating transmission cylinder 51 can push the two sliding shafts 53 to move synchronously through the two guide grooves 511, moving closer or further away from each other, so that the sliding shafts 53 drive the ring sleeves 52 and the calibration discs 41 to move. The push rod 43 clamps the waste collection cylinder in the middle of the outer cylinder 31 or releases the clamp.

[0035] The ring 52 consists of an inner ring 521 and an outer ring 522. The inner ring 521 is coaxially rotatably mounted inside the outer ring 522. The sliding shaft 53 is fixedly installed on the inner ring 521. The calibration disk 41 is fixedly connected to the outer ring 522. An inner magnet 523 is fixedly installed on the inner ring 521, and an outer magnet 524 is fixedly installed on the outer ring 522. The inner magnet 523 and the outer magnet 524 attract each other, so that when the inner ring 521 rotates with the inner cylinder 33, the inner magnet 523 and the outer magnet 524 attract each other. The magnetic attraction drives the outer ring 522 to rotate, which in turn drives the calibration disk 41 to rotate, allowing the push rod 43 to extend out of the axial groove 22. When the calibration disk 41 is restricted from moving further due to the push rod 43 clamping the waste collection cylinder, the pushing force of the transmission cylinder 51 on the inner ring 521 during rotation can overcome the magnetic attraction between the inner magnet 523 and the outer magnet 524, thereby causing the inner ring 521 to rotate inside the outer ring 522 without interfering with the normal rotation of the transmission cylinder 51 and the inner cylinder 33.

[0036] refer to Figure 3 as well as Figure 7 The positioning mechanism 60 includes an external threaded cylinder 61, a threaded sleeve 62, a connecting rod 63, and a positioning plate 64. The external threaded cylinder 61 is coaxially disposed outside the inner cylinder 33 and can rotate under the drive of the inner cylinder 33. The threaded sleeve 62 is threadedly connected to the external threaded cylinder 61. There are multiple connecting rods 63 and multiple positioning plates 64. Multiple connecting rods 63 are rotatably assembled on the threaded sleeve 62. Multiple positioning plates 64 are rotatably assembled on the ends of multiple connecting rods 63 away from the threaded sleeve 62, and multiple positioning plates 64 are slidably assembled inside multiple positioning grooves 311. When the inner cylinder 33 rotates, it drives the external threaded cylinder 61 to rotate, pushes the threaded sleeve 62 to move, and causes the connecting rod 63 to rotate and push the positioning plate 64 to slide outward in the positioning groove 311. Then, the inside of the waste collection cylinder tensions and fixes it.

[0037] refer to Figure 3 and Figure 4 The drive mechanism 70 includes a central shaft 71, a guide groove 72, and a guide shaft 73. The central shaft 71 is coaxially fixed inside the circular cavity 21, and the inner cylinder 33 is coaxially sleeved on the outside of the central shaft 71. The guide groove 72 is opened on the central shaft 71, and the guide shaft 73 is slidably assembled in the guide groove 72 and fixed to the inner cylinder 33. By sliding the guide shaft 73 in the guide groove 72, the inner cylinder 33 can move and rotate accordingly outside the central shaft 71.

[0038] The guide groove 72 consists of a straight groove 721 and a spiral groove 722. The straight groove 721 is opened along the axial direction of the central shaft 71, and the spiral groove 722 is opened on the end side of the central shaft 71 and connected to the straight groove 721. When the guide shaft 73 slides along the straight groove 721, the inner cylinder 33 can only slide with a single degree of freedom outside the central shaft 71. When the guide shaft 73 enters the spiral groove 722, the inner cylinder 33 can rotate relative to the central shaft 71, thereby driving the transmission mechanism 50 and the positioning mechanism 60 to operate. An electric telescopic rod 711 is fixedly installed at the end of the central shaft 71 away from the spiral groove 722, and the telescopic end of the electric telescopic rod 711 is fixed to the connecting frame 32. Through the telescopic extension and retraction of the electric telescopic rod 711, the connecting frame 32 and the inner cylinder 33 are moved in the circular cavity 21.

[0039] The external threaded cylinder 61 and the inner cylinder 33 are rotatably connected, and a torsion spring is provided between the external threaded cylinder 61 and the inner cylinder 33. The two ends of the torsion spring are fixed to the external threaded cylinder 61 and the inner cylinder 33 respectively, so that when the inner cylinder 33 rotates, it drives the external threaded cylinder 61 to rotate through the torsion spring. When the waste collection cylinder is fixed and the external threaded cylinder 61 cannot rotate, the inner cylinder 33 continues to rotate and will compress the torsion spring, thus not affecting the rotation of the inner cylinder 33, so that the inner cylinder 33 can move better along the guide groove 72.

[0040] Working principle: The electric telescopic rod 711 pushes the connecting frame 32, which drives the outer cylinder 31 and the inner cylinder 33 to move towards the end of the winding roller 20, and sends the support cylinder 30 and the waste collection cylinder out from directly below the frame 10. During this process, the inner cylinder 33 slides in the straight groove 721 with the guide shaft 73 as it moves. When the guide shaft 73 approaches the end of the central shaft 71 and enters the spiral groove 722, it will rotate the moving inner cylinder 33.

[0041] The transmission cylinder 51 rotates with the inner cylinder 33, pushing the sliding shaft 53 to rotate with the ring 52, causing the calibration disc 41 to rotate with the arc groove 42, and retracting the push rod 43 into the axial groove 22. When the end of the push rod 43 moves to the end of the arc groove 42, the calibration disc 41 can no longer rotate. Then, in the rotation of the transmission cylinder 51, the guide groove 511 pushes the sliding shaft 53 to move, causing the two calibration discs 41 with the push rod 43 to move away from each other, thereby releasing the clamping of the waste collection cylinder. When the sliding shaft 53 moves to the end of the guide groove 511, the inner ring 521, in the continuous rotation of the transmission cylinder 51, overcomes the magnetic force between the inner magnet 523 and the outer magnet 524 and rotates in the outer ring 522, thus not interfering with the continuous rotation of the transmission cylinder 51 and the inner cylinder 33.

[0042] The external threaded cylinder 61 rotates synchronously under the drive of the inner cylinder 33, pushing the threaded sleeve 62 to move, causing the connecting rod 63 to drive the positioning plate 64 to descend and completely retract it into the positioning groove 311, releasing the fixation of the waste collection cylinder. Then, the waste collection cylinder full of waste is removed from the outer cylinder 31 and replaced with a new one. Then, the electric telescopic rod 711 retracts, causing the connecting frame 32 to move back to its original position, so that the inner cylinder 33 first rotates under the action of the spiral groove 722. The transmission cylinder 51 drives the calibration plate 41 to rotate, causing the push rod 43 to extend out of the axial groove 22. Then, the two calibration plates 41 approach each other under the action of the guide groove 511, so that the push rod 43 clamps the waste collection cylinder in the middle part of the outer cylinder 31. At the same time, the external threaded cylinder 61 rotates with the inner cylinder 33, causing the threaded sleeve 62 to drive the positioning plate 64 to rise and extend out of the positioning groove 311, thus tensioning and fixing the waste collection cylinder.

[0043] Finally, the support cylinder 30 brings the fixed waste collection cylinder back to the bottom of the frame 10. The collection tape for collecting die-cut waste is fixed on the waste collection cylinder after passing through the die-cutting roller 12 and the guide roller 13. The winding roller 20 rotates to wind it up.

[0044] In this invention, the waste collection cylinder is supported by the support cylinder 30, which provides better support and fixation so that it can rotate with the take-up roller 20 to collect the tape. The movement of the support cylinder 30 can effectively send the waste collection cylinder into or out of the bottom of the frame 10. During the sending process, the position is automatically calibrated and fixed, and during the sending process, the fixation is automatically released. The operation is simple and quick, which makes it easier for the staff to replace and place the waste collection cylinder. It effectively reduces the impact of the machine tool on the replacement of the waste collection cylinder, reduces the manual operation procedures during the replacement and disassembly process, and makes the replacement of the waste collection cylinder more efficient and safe.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
