Description

Technical Field

[0001] The invention relates to the technical field of film soft bag packaging equipment, and in particular to a movable cutting knife frame mechanism. Background Art

[0002] In the vertical film soft bag multi-row packaging machine industry, the cutter mechanism used for slitting film is difficult to adjust during use, and there are complex and time-consuming problems when replacing and maintaining the cutter. The main reason is that the existing cutter mechanism is generally fixed in the frame, so the cutter mechanism cannot move along its own axis. As a result, when the cutter mechanism is operated inside the frame, due to the limited internal space of the frame, the operator cannot observe the use of the cutter and other related parts. In addition, when used in an environment with insufficient lighting in the workshop, it is even more difficult for the operator to operate. Summary of the invention

[0003] The object of the present invention is to provide a mobile slitting knife frame mechanism, which has the advantage that the cutter mechanism can be conveniently pushed in or pulled out from the frame to facilitate the maintenance and inspection of the cutter mechanism, and can effectively alleviate the maintenance inconvenience caused by traditional fixed installation, thereby facilitating the humanized improvement of the maintenance efficiency of the cutter mechanism.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: a mobile slitting knife frame mechanism, including a frame, the frame is provided with a feeding mechanism for conveying a film, the frame is rotatably connected to a first slide rail, and the first slide rail is slidably connected to a cutter mechanism for cutting a film; the cutter mechanism is locked to the frame by a locking device.

[0005] By adopting the above technical scheme, after the cutter mechanism is unlocked from the frame by the locking device, the cutter mechanism is driven to flip around the axial direction of the first slide rail to leave the feeding mechanism, so that the purpose of suspending the film cutting work can be achieved; then, the cutter mechanism can be driven to be pulled out of the frame along the axial direction of the first slide rail to facilitate daily maintenance and overhaul operations on the cutter mechanism. Since the conventional cutter mechanism is fixedly arranged on the frame, this scheme can effectively alleviate the maintenance inconvenience caused by the traditional fixed installation, thereby facilitating the humanized improvement of the maintenance efficiency of the cutter mechanism; and since the cutter mechanism can be flipped at a certain angle, the cutter mechanism can be pushed and pulled and extended, and can also be swung and adjusted, thereby having the advantages of saving space and being simple and quick to operate.

[0006] According to a further configuration of the present invention, the locking device includes a first locking portion arranged at the end of the cutter mechanism, a second locking portion arranged at the side of the frame, and a locking piece, wherein the second locking portion matches the first locking portion; the locking piece passes through the first locking portion and the second locking portion and is locked on the first locking portion.

[0007] According to a further configuration of the present invention, the cutter mechanism comprises a cutter shaft and a cutter group arranged on the cutter shaft, the side wall of the first slide rail is provided with a first connecting pair along its own axial sliding sleeve, and the cutter shaft is arranged on a side of the first connecting pair away from the first slide rail.

[0008] A further configuration of the present invention is that the first connecting pair is provided with a first through hole matching the cutter shaft, the cutter shaft is passed through the first through hole, a first opening connected to the first through hole is opened on the side wall of the first connecting pair away from the first slide rail, and the first connecting pair is provided with a first fastener that can pass through the first opening.

[0009] By adopting the above technical solution, the setting of the cutter shaft can leave a distance between the cutter group and the first slide rail, so that the cutter group can rotate around the first slide rail; the installation and disassembly of the cutter shaft on the first connecting pair can be achieved through the first fastener, so as to further facilitate the maintenance of the cutter mechanism and improve its maintenance efficiency.

[0010] According to a further configuration of the present invention, a positioning opening matching the outer contour of the cutter shaft is provided on the frame, and an arc-shaped smooth portion is provided at a notch of the positioning opening close to the first slide rail to facilitate the cutter shaft to slide into the positioning opening.

[0011] By adopting the above technical solution, when the cutter mechanism is flipped over to the feeding mechanism for positioning before film cutting, the cutter shaft slides into the positioning opening along the arc-shaped smooth portion to improve the positioning of the cutter shaft and the cutter group arranged thereon before processing.

[0012] According to a further configuration of the present invention, the first slide rail includes a first sleeve and a sliding shaft, the first sleeve is rotatably connected to the frame, the first sleeve is provided with a sliding hole matching the sliding shaft along its own axial direction, and the sliding shaft is slidably connected in the sliding hole; one end of the cutting mechanism is arranged on the side wall of the first sleeve, and the other end is arranged on the sliding shaft.

[0013] By adopting the above technical solution, after the cutter mechanism is unlocked from the frame by the locking device, the cutter mechanism is driven to flip around the axial direction of the first sleeve. Since the sliding shaft slides in the first sleeve, the cutter mechanism can follow the sliding shaft and move out of the frame along the axial direction of the first sleeve.

[0014] According to a further configuration of the present invention, receiving grooves are symmetrically provided on both sides of the frame, and a receiving shaft is provided between the two receiving grooves for placement when the cutter mechanism is moved out.

[0015] By adopting the above technical solution, the receiving groove is in a 7-shape. When the receiving shaft is placed at the bottom of the receiving groove, the receiving shaft and the receiving groove are in a non-contact state; when the receiving shaft is placed at the top of the receiving groove, the cutter mechanism can be directly placed on the receiving shaft during the process of moving out of the frame, so as to reduce the discomfort caused by the operator lifting the cutter mechanism for a long time, and the receiving shaft can be easily moved in the receiving groove, which further facilitates the use of the operator.

[0016] According to a further configuration of the present invention, a limiting column capable of abutting against the cutter mechanism is threadedly provided on the frame.

[0017] By adopting the above technical solution, since the limit column can be in contact with the cutter mechanism, the position of the cutter mechanism in the frame can be adjusted by adjusting the length of the limit column extending from the side of the frame close to the first connecting pair, thereby facilitating the cutting position of the cutter mechanism on the feeding mechanism to adapt to different film cutting requirements.

[0018] According to a further configuration of the present invention, a second sleeve is sleeved on the side wall of the first slide rail along its own axial sliding; one end of the first connecting pair is sleeved and fixed on the second sleeve, and the cutter mechanism is arranged on the other end of the first connecting pair.

[0019] By adopting the above technical solution, the cutter mechanism is slidable on the first slide rail through the combination of the first connection pair and the microphone sleeve. Therefore, on the basis of realizing the rotation of the cutter mechanism, the cutter mechanism can also be pushed in and pulled out on the first slide rail.

[0020] According to a further configuration of the present invention, the feeding mechanism comprises a feeding roller which can match the cutting mechanism for cutting, the feeding roller is arranged axially parallel to the cutting mechanism, and the feeding roller is rotatably connected to the frame.

[0021] By adopting the above technical scheme, the film is generally placed directly in the traditional feeding mechanism. Therefore, when the film needs to move forward along the feeding direction, one end of the film needs to be pulled manually to realize the feeding of the film; but by combining the hand wheel with the feeding roller, the feeding roller can be driven to rotate at a constant speed by the hand wheel to realize the feeding of the film, so as to reduce the phenomenon of uneven cutting and other defective products caused by hand-pulling the film; combined with the easily adjustable cutter mechanism in this scheme, the cutting processing quality of the film can be effectively improved.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The cutter mechanism can be easily pushed in or pulled out from the frame, which is convenient for maintenance and repair of the cutter mechanism;

[0024] 2. It can effectively reduce the maintenance inconvenience caused by traditional fixed installation, thereby facilitating the humanized improvement of the maintenance efficiency of the cutter mechanism;

[0025] 3. The movable cutter mechanism saves more space and is easy and quick to operate;

[0026] 4. The position of the cutter mechanism in the frame can be adjusted to meet different film cutting requirements;

[0027] In general, the present invention can conveniently push or pull the cutter mechanism into or out of the frame, so as to facilitate the maintenance and inspection of the cutter mechanism, which can effectively alleviate the maintenance inconvenience caused by the traditional fixed installation, and further facilitate the humanized improvement of the maintenance efficiency of the cutter mechanism.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] Embodiment: A movable cutting tool holder mechanism, such as Figures 1 to 7 As shown, it includes a frame 1, on which a feeding mechanism 3 for conveying a film is provided, a first slide rail 2 is rotatably connected to the frame 1, and a cutter mechanism 4 for cutting a film is slidably connected to the first slide rail 2; the cutter mechanism 4 is locked to the frame 1 by a locking device 5.

[0038] There are two locking devices 5 , which are respectively arranged at two axial ends of the cutter mechanism 4 .

[0039] After the cutter mechanism 4 is unlocked from the frame 1 by the locking device 5, the cutter mechanism 4 is driven to flip around the axial direction of the first slide rail 2 to leave the feeding mechanism 3, so that the purpose of suspending the film cutting work can be achieved; then, the cutter mechanism 4 can also be driven to be pulled out of the frame 1 along the axial direction of the first slide rail 2, so as to facilitate daily maintenance and overhaul operations on the cutter mechanism 4. Since the conventional cutter mechanism 4 is fixedly arranged on the frame 1, this solution can effectively alleviate the maintenance inconvenience caused by the traditional fixed installation, thereby facilitating the humanized improvement of the maintenance efficiency of the cutter mechanism 4; and, since the cutter mechanism 4 can be flipped at a certain angle, the cutter mechanism 4 can be pushed and pulled and extended, and can also be swung and adjusted, thereby having the advantages of saving space and being simple and quick to operate.

[0040] The locking device 5 includes a first locking portion 51 arranged at the end of the cutter mechanism 4, a second locking portion 52 arranged on the side of the frame 1, and a locking piece 53, the second locking portion 52 matches the first locking portion 51; the locking piece 53 passes through the first locking portion 51 and the second locking portion 52 and is locked on the first locking portion 51.

[0041] The first locking portion 51 includes a first locking block 511. The first locking block 511 is integrally formed with a first intersecting block 6 on the side wall near the second locking portion 52. The first locking block 511 is formed with a second opening 7 for the locking member 53 to pass through. The locking member 53 passes through the second locking portion 52 and is locked on the first intersecting block 6. Before the cutter mechanism 4 flips around the first slide rail 2 to the feeding mechanism 3 for film cutting, the first intersecting block 6 corresponds to the second locking portion 52. At this time, the locking member 53 is threaded through the second locking portion 52 and the first intersecting block 6 in sequence and then threadedly locked on the first intersecting block 6.

[0042] In this embodiment, the first intersection block 6 and the first locking block 511 are integrally formed by sheet metal processing, and the second opening 7 is formed between the first intersection block 6 and the first locking block 511 during the sheet metal processing. The use of sheet metal processing can easily reduce the production cost of the equipment.

[0043] The cutter mechanism 4 includes a cutter shaft 41 and a cutter group 42 disposed on the cutter shaft 41. The side wall of the first slide rail 2 is provided with a first connection pair 9 along its own axial sliding sleeve, and the cutter shaft 41 is disposed on the side of the first connection pair 9 away from the first slide rail 2. The cutter group 42 includes a plurality of cutting blades, and the plurality of cutting blades are evenly distributed along the axial direction of the cutter shaft 41. The arrangement of the cutter shaft 41 allows a spacing to be left between the cutter group 42 and the first slide rail 2, so that the cutter group 42 can rotate around the first slide rail 2.

[0044] The first connection pair 9 is provided with a first through hole 10 matching with the cutter shaft 41, the cutter shaft 41 is inserted into the first through hole 10, a first opening 11 communicating with the first through hole 10 is provided on the side wall of the first connection pair 9 away from the first slide rail 2, and a first fastener 12 that can pass through the first opening 11 is inserted into the first connection pair 9. The first fastener 12 can realize the installation and removal of the cutter shaft 41 on the first connection pair 9, so as to further facilitate the maintenance of the cutter mechanism 4 and improve its maintenance efficiency.

[0045] In this embodiment, the first through hole 10 is a threaded hole, the first fastener 12 is a bolt pair, and the first fastener 12 is threadedly connected and passes through the second locking portion 52 and the first junction block 6 at one time.

[0046] The frame 1 is provided with a positioning opening 13 matching the outer contour of the cutter shaft 41, and the positioning opening 13 is provided with an arc-shaped smooth portion 14 near the notch of the first slide rail 2 to facilitate the cutter shaft 41 to slide into the positioning opening 13. When the cutter mechanism 4 is flipped over to the feeding mechanism 3 for positioning before the film cutting process, the cutter shaft 41 slides into the positioning opening 13 along the arc-shaped smooth portion 14 to improve the positioning of the cutter shaft 41 and the cutter group 42 arranged thereon before processing.

[0047] The frame 1 is threadedly provided with a limit post 15 that can abut against the cutter mechanism 4. In this embodiment, the limit post 15 abuts against the first connection pair 9, so by adjusting the length of the limit post 15 extending from the side of the frame 1 close to the first connection pair 9, the position of the cutter mechanism 4 in the frame 1 can be adjusted, thereby facilitating the cutting position of the cutter mechanism 4 on the feeding mechanism 3, so as to adapt to different film cutting requirements. In this embodiment, the limit post 15 is a screw threadedly provided on the frame 1.

[0048] The side wall of the first slide rail 2 is provided with a second sleeve 16 along its own axial sliding; one end of the first connection pair 9 is sleeved and fixed on the second sleeve 16, and the cutter mechanism 4 is provided on the other end of the first connection pair 9. The cutter mechanism 4 is realized to slide on the first slide rail 2 through the combination of the first connection pair 9 and the microphone sleeve, so that on the basis of realizing the rotation of the cutter mechanism 4, the cutter mechanism 4 can also be pushed in and pulled out on the first slide rail 2. In this embodiment, the inner wall of the second sleeve 16 is uniformly provided with a plurality of groups of grooves, and the grooves extend along the axial direction of the second sleeve 16, and the outer wall of the second sleeve 16 is uniformly provided with a plurality of square protrusions around its own outer contour.

[0049] The first slide rail 2 includes a first sleeve 21 and a sliding shaft 22. The first sleeve 21 is rotatably connected to the frame 1. The first sleeve 21 is provided with a sliding hole 23 matching the sliding shaft along its own axial direction. The sliding shaft 22 is slidably connected in the sliding hole 23. One end of the cutter mechanism 4 is arranged on the side wall of the first sleeve 21, and the other end is arranged on the sliding shaft 22, that is, the second sleeve 16 is sleeved on the outer wall of the first sleeve 21.

[0050] The end of the sliding shaft is provided with a second connection pair located outside the frame. The technical structure of the second connection pair is similar to that of the first connection pair. The cutter shaft is passed through the end of the second connection pair away from the sliding shaft.

[0051] After the cutting mechanism 4 is unlocked from the frame 1 by the locking device 5, the cutting mechanism 4 is driven to flip around the axial direction of the first sleeve 21. Since the sliding shaft slides in the first sleeve 21, the cutting mechanism 4 can follow the sliding shaft and move out of the frame 1 along the axial direction of the first sleeve 21.

[0052] Receiving grooves 8 are symmetrically provided on both sides of the frame 1 , and a receiving shaft 81 is provided between the two receiving grooves 8 for placement when the cutter mechanism 4 is moved out.

[0053] The receiving groove 8 is in the shape of an Arabic numeral 7. When the receiving shaft 81 is placed at the bottom of the receiving groove 8, the receiving shaft 81 and the receiving groove 8 are in a non-contact state; when the receiving shaft 81 is placed at the top of the receiving groove 8, the cutter mechanism 4 can be directly placed on the receiving shaft 81 during the process of moving out of the frame 1, so as to reduce the discomfort caused by the operator holding the cutter mechanism 4 for a long time, and the receiving shaft 81 can be easily moved in the receiving groove 8, which further facilitates the use of the operator.

[0054] The feeding mechanism 3 includes a feeding roller 31 that can match the cutting mechanism 4 for cutting. The feeding roller 31 is arranged axially parallel to the cutting mechanism 4. The feeding roller 31 is rotatably connected to the frame 1. A handwheel 32 is provided at the end of the feeding roller 31. The handwheel 32 can also be used as a detachable type, but is not limited to this. The handwheel 32 can also be replaced by a servo motor-type power device.

[0055] The film is generally placed directly in the traditional feeding mechanism 3, so when the film needs to move forward along the feeding direction, one end of the film needs to be pulled manually to achieve the feeding of the film; but after the hand wheel 32 is combined with the feeding roller 31, the feeding roller 31 can be driven to rotate at a constant speed by the hand wheel 32 to achieve the feeding of the film, so as to reduce the phenomenon of uneven cutting and other defective products caused by hand-pulling the film; combined with the easily adjustable cutter mechanism 4 in this scheme, the cutting processing quality of the film can be effectively improved.

[0056] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
