Description

Technical Field

[0001] This invention relates to the field of film feeding devices, and more specifically to a packaging film feeding and cutting mechanism. Background Technology

[0002] The working process of the packaging film feeding and cutting mechanism is as follows: unfold the roll of packaging film so that it can enter the next processing step, guide the packaging film into the cutting mechanism to ensure its accurate position for cutting or processing, cut the packaging film according to the required size or shape, and send the cut packaging film to the ashtray position for lamination.

[0003] When laminating ashtrays, they are conveyed from the conveyor belt to the film feeding device. Because the pattern to be laminated must match the opening of the ashtray, workers need to constantly observe whether the ashtrays on the production line are placed with their openings facing upwards. If they are not placed with their openings facing upwards, workers need to manually flip the ashtrays to match the lamination pattern. However, in long-term production, oversights are inevitable when correcting these issues by manual observation, resulting in some ashtrays not being placed with their openings facing upwards. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are:

This drive method is suitable for situations with small load weight and short transfer distance. The structure is simple and easy to maintain.

[0015] (2) The gripping component can detect and grip ashtrays with the bottom facing up. After the gripping component moves the ashtray to flip over, the force rod is squeezed by the baffle plate and the detection component is reset. This avoids the gripping component being unable to put down the ashtray if it is not reset, and also avoids affecting the next gripping task. If the ashtray is open at the top, the measuring rod will detect it, so the gripping component will not grip the ashtray. This will prevent the sliding rod from being stretched. The sliding rod with a short stroke will not be squeezed by the baffle plate, so the irregular groove slider will not move, so the next gripping of the gripping component will not be affected.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please refer to Figure 1 and Figure 3 As shown, a packaging film feeding and cutting mechanism includes a packaging film device 1. A fixed bracket 2 is fixedly installed on the right side of the packaging film device 1. One end of the fixed bracket 2 is rotatably connected to one end of a telescopic rod 3. A hinge 31 is fixed to the other end of the telescopic rod 3. A drive assembly 4 is hinged to the hinge 31. The drive assembly 4 is used to change the drive trajectory of the telescopic rod 3. A gripping assembly 6 is fixedly installed on the upper part of the drive assembly 4. The gripping assembly 6 is used to grip an ashtray 9. A synchronization assembly 5 is installed on the lower part of the drive assembly 4. The gripping assembly 6 is installed at the end of the synchronization assembly 5. Baffles 7 are fixedly installed on the left and right sides of the conveyor belt of the packaging film device 1.

[0027] Working principle: When the ashtray 9 is conveyed to the front of the packaging film equipment 1 by the conveying device, the telescopic rod 3 is activated. The telescopic rod 3 drives the drive assembly 4 to operate, which in turn drives the synchronization assembly 5. Through the reciprocating motion of the drive assembly 4 and the synchronization assembly 5, the gripping assemblies 6 located on the right and left sides of the packaging film equipment 1 reciprocate. The gripping assemblies 6 first rotate and press towards the ashtray 9. When the open end of the ashtray 9 faces downward, the bottom of the ashtray 9 faces upward. At this time, the gripping assembly... The ashtray 6 will be squeezed by the bottom of the ashtray 9, causing the gripping component 6 to move. The gripping component 6 will then lock into the groove in the middle of the ashtray 9, so that the left and right gripping components 6 cooperate to grip the ashtray 9. At this time, the gripping component 6 will drive the ashtray 9 to rotate in another direction. When the gripping component 6 drives the ashtray 9 to rotate to the end face of the conveyor belt of the packaging film equipment 1, the gripping component 6 will squeeze the blocking plate 7, thereby releasing the locking state of the ashtray 9. At this time, the ashtray 9 can move with the conveyor belt of the packaging film equipment 1, thereby completing the flipping of the ashtray 9.

[0028] Example 2

[0029] Please refer to Figure 2 and Figure 3 As shown, the drive assembly 4 includes: a drive tooth 41, a transmission tooth 42, a transmission gear shaft 43, and a connecting handle 430. The middle part of the drive tooth 41 is fixedly connected to the end of the right gripping assembly 6. The drive tooth 41 meshes with the transmission tooth 42. The rotation shaft of the transmission tooth 42 is fixedly connected to the right side of the packaging film equipment 1. The transmission tooth 42 meshes with the transmission gear shaft 43. The right side of the transmission gear shaft 43 is fixedly connected to one end of the connecting handle 430. The other end of the connecting handle 430 is hinged to the end of the hinge member 31.

[0030] The transmission gear shaft 43 further includes: a rotating shaft 431 and a fixing block 432. The middle part of the transmission gear shaft 43 is fixedly connected to the rod of the rotating shaft 431. One end of the rotating shaft 431 is fixedly connected to the end of the connecting handle 430. The other end of the rotating shaft 431 is fixedly connected to the lower part of the synchronization component 5. Multiple fixing blocks 432 are fixedly connected through the rod of the rotating shaft 431. The ends of the fixing blocks 432 are fixedly connected to the lower part of the packaging film equipment 1.

[0031] The synchronization component 5 includes: a first fixed disk 51, a linkage rod 52, and a second fixed disk 53. The middle part of the second fixed disk 53 is fixedly connected to the end of the rotating shaft 431. The end face of the second fixed disk 53 is rotatably connected to one end of the linkage rod 52. The other end of the linkage rod 52 is rotatably connected to the end face of the first fixed disk 51. The middle part of the first fixed disk 51 is fixedly connected to the lower part of the left gripping component 6.

[0032] Working principle: When telescopic rod 3 is activated, it will rotate against connecting handle 430. Figure 2 (Based on the reference) the connecting handle 430 drives the transmission gear shaft 43 to rotate counterclockwise, the transmission gear shaft 43 drives the transmission gear 42 to rotate clockwise, and the transmission gear 42 drives the drive gear 41 to rotate counterclockwise. The drive gear 41 drives the gripping component 6 on the right side of the packaging film equipment 1 to rotate toward the ashtray 9. The rotating shaft 431 is fixedly connected to the fixed disk 53, and the fixed disk 53 rotates synchronously with the transmission gear shaft 43. The fixed disk 53 drives the fixed disk 51 to rotate synchronously through the linkage rod 52, so that the linkage rod 52 drives the fixed disk 51 to rotate synchronously. The gripping component 6 on the left side of the packaging film equipment 1 rotates toward the ashtray 9, so that the gripping components 6 on both sides of the packaging film equipment 1 can rotate synchronously. This allows the gripping components 6 on both sides to cooperate in transferring and flipping the ashtray 9. This structure can avoid asynchronous movement of the gripping components 6 on the left and right sides, making the transfer of the ashtray 9 more stable. The movement of the drive component 4 and the synchronization component 5 is controlled by the telescopic rod 3. This drive method is suitable for situations with small load weight and short transfer distance. The structure is simple and easy to maintain.

[0033] Example 3

[0034] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the gripping assembly 6 includes: a fixed post 61, a steering arm 62, a detection element 63, a depth probe 64, a force-bearing rod 641, a measuring rod 642, and a locking rod 65. The rotation shaft of the steering arm 62 is rotatably connected to the frame of the conveyor belt of the packaging film equipment 1. One end of the steering arm 62 is fixedly connected to one end of the fixed post 61, and the other end of the fixed post 61 is fixedly connected to one side of the detection element 63. The other end of the detection element 63 is fixedly connected to the end face of the locking rod 65. One end of the detection element 63 is fixedly connected to the rod body of the depth probe 64, one end of the depth probe 64 is fixedly connected to the end of the measuring rod 642, and the other end of the depth probe 64 is fixedly connected to the end of the force-bearing rod 641.

[0035] The locking rod 65 further includes: a plug rod 651, a spring rod 652, and a spring 653. The plug rod 651 is slidably connected to the slots at both ends of the locking rod 65. The end of the plug rod 651 is fixedly connected to the end of the spring rod 652. The end face of the spring rod 652 is fixedly connected to one end of the spring 653. The other end of the spring 653 is fixedly connected to the end face of the locking rod 65.

[0036] The detection component 63 further includes: a shaped groove slider 631, a sliding limit rod 632, and a spring 633. The groove on the end face of the detection component 63 is slidably connected to the column of the shaped groove slider 631. The shaped groove on the end face of the shaped groove slider 631 is slidably connected to one end of the sliding limit rod 632. The other end of the sliding limit rod 632 is rotatably connected to the inner wall of the detection component 63. The end of the shaped groove slider 631 is fitted with a spring 633.

[0037] The irregular groove slider 631 further includes: a sliding rod 601 and a trapezoidal drive block 602. The end of the irregular groove slider 631 is fixedly connected to one end of the sliding rod 601. The rod body of the sliding rod 601 is slidably connected to a hole opened at the end of the detection element 63. The other end of the sliding rod 601 is fixedly connected to the rod body of the depth probe 64. The column of the end face of the irregular groove slider 631 is fixedly connected to the end of the trapezoidal drive block 602.

[0038] Working principle: When the gripping component 6 moves toward the ashtray 9 with its bottom surface facing upwards, the free end of the measuring rod 642 will first contact the bottom of the ashtray 9. As the gripping component 6 continues to move, the measuring rod 642 will be compressed, and the locking rod 65 will move toward the groove in the middle of the ashtray 9 until both are at the same level. The measuring rod 642 is fixedly connected to the probe 64, and the probe 64 is fixedly connected to the sliding rod 601. Therefore, the irregular groove slider 631 will move toward the probe 64 under the constraint of the detection component 63. During this process, the spring 601... 33 will be compressed, and the sliding limit rod 632 will slide along half of the irregular groove of the irregular groove slider 631. The end face of the irregular groove slider 631 is fixedly connected to the trapezoidal drive block 602, so the trapezoidal drive block 602 will also move synchronously with the irregular groove slider 631. During this process, the inclined surface of the trapezoidal drive block 602 will abut against the elastic rod 652, so that after the elastic rod 652 is squeezed, the elastic rod 652 moves towards the end face of the locking rod 65, and the insertion rod 651 connected to the end of the elastic rod 652 will move synchronously. The insertion rod 651 will slide under the restriction of the groove at the end of the locking rod 65. Rod 651 inserts into the groove in the middle of ashtray 9, thereby gripping and locking ashtray 9. Sliding limit rod 632 slides to the recess of the irregular groove slider 631, at which point the irregular groove slider 631 is fixed. The irregular groove slider 631 drives the trapezoidal drive block 602 to continuously apply pressure to the spring rod 652, causing the insertion rod 651 to continuously lock ashtray 9, preventing ashtray 9 from loosening and falling during the transfer and flipping process. When the locked ashtray 9 is transferred to another position by the gripping component 6, the extended sliding rod 601 will first drive the force rod 641. When the ashtray 9 is blocked by the baffle plate 7, it is in a horizontal flipped state. When the gripping component 6 moves slightly upward, the sliding limit rod 632, which is stuck in the recess of the irregular groove slider 631, will reset from the other half of the irregular groove. This will cause the spring three 633 to drive the irregular groove slider 631 to drive the sliding rod 601 to reset. At this time, the trapezoidal drive block 602 will no longer be able to apply pressure to the elastic rod 652, causing the spring one 653 to drive the elastic rod 652 to drive the insertion rod 651 to reset. At this time, the ashtray 9 can no longer be stuck by the gripping component 6, so that the ashtray 9 falls onto the conveyor belt of the packaging film equipment 1.

[0039] The gripping component 6 can detect and grip the ashtray 9 with its bottom facing upwards. After the gripping component 6 moves the ashtray 9 to rotate and flip, the force rod 641 is squeezed by the baffle plate 7, causing the detection element 63 to reset. This prevents the gripping component 6 from being unable to put down the ashtray 9 if it is not reset, and also avoids affecting the next gripping task. If the ashtray 9 is with its open end facing upwards, the measuring rod 642 will detect it, so the gripping component 6 will not grip the ashtray 9. This will prevent the sliding rod 601 from being stretched, and the sliding rod 601 with a short stroke will not be squeezed by the baffle plate 7. Therefore, the irregular groove slider 631 will not move, so the next gripping by the gripping component 6 will not be affected.
