Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate processing, in particular to an anti-crack groove cutting device and a plate production system. Background Art
[0002] Some boards (e.g., aerated concrete boards) need to have grooves cut on their surfaces to reduce the generation and expansion of cracks in the material caused by stress, temperature changes or environmental factors. The grooves are called anti-crack grooves. At present, aerated concrete board production lines generally use a slitting device to process anti-crack grooves on aerated concrete boards. The slitting device includes a pair of slitting mechanisms. When the board passes between a pair of slitting mechanisms, the pair of slitting mechanisms can process anti-crack grooves on the two surfaces of the board respectively.
[0003] Since the plates have different specifications, the plates of different specifications have different requirements for the spacing of the anti-crack grooves. This requires that a slitting mechanism with slitting knives having corresponding spacing be selected for plates of different specifications during the manufacturing process. Each slitting mechanism of some prior art slitting devices has at least two knife shafts, and the spacing of the slitting knives on each knife shaft is different. Although each slitting mechanism can adapt to the processing of plates of at least two specifications, which increases the adaptability of the slitting mechanism to plates of different specifications to a certain extent, the increase in the number of knife shafts will result in a larger space required for the slitting mechanism. The number of knife shafts that can be set for each slitting mechanism is extremely limited, and its adaptability is limited. For the processing of plates of other specifications, it is still necessary to equip a variety of slitting mechanisms, which is costly. Utility Model Content

[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] Combine the following Figures 1 to 6 The utility model is described in detail.
[0038] like Figures 1 to 6As shown, the anti-crack groove cutting device provided by the embodiment of the utility model includes a support frame 1, a pair of cutting mechanisms 2 and a driving mechanism.
[0039] Specifically, a pair of slitting mechanisms 2 are disposed on the support frame 1 , each slitting mechanism 2 is rotatably connected to the support frame 1 , and the pair of slitting mechanisms 2 are parallel to the rotation axis of the support frame 1 .
[0040] There is a space between the pair of slitting mechanisms 2 for the plate 3 to pass through. When the plate 3 passes through the pair of slitting mechanisms 2, the pair of slitting mechanisms 2 can process anti-crack grooves on two opposite surfaces of the plate 3.
[0041] The slitting mechanism 2 includes at least two knife groups 9 , the axes of the knife groups 9 are parallel, and the knife groups 9 are spaced apart around the rotation axis of the slitting mechanism 2 relative to the support frame 1 .
[0042] The driving mechanism is used to drive the slitting mechanism 2 to rotate relative to the support frame 1. When the slitting mechanism 2 rotates relative to the support frame 1, different knife groups 9 can correspond to the plate 3, and the corresponding knife groups 9 can be switched between the cutting position and the retracting position.
[0043] It should be noted that when the knife group 9 can interact with the plate 3, the position of the knife group 9 is called the cutting position of the knife group 9; when the knife group 9 is out of contact with the plate 3, the position of the knife group 9 is called the knife withdrawal position of the knife group 9. When the slitting mechanism 2 has at least two knife groups 9, the slitting mechanism 2 has at least two cutting positions, and the number of the cutting positions of the slitting mechanism 2 is the same as the number of the knife groups 9.
[0044] The knife group 9 includes a knife shaft 14 and at least two cutting knives 15. The cutting knives 15 are arranged on the knife shaft 14, and the position of any cutting knife 15 on the knife shaft 14 is adjustable. By adjusting the position of the cutting knife 15 on the knife shaft 14, the spacing between the cutting knives on the knife shaft 14 can be adjusted.
[0045] With such a configuration, by adjusting the distance between the cutting blades on the blade shaft 14, different blade groups 9 of each slitting mechanism 2 can correspond to different distance between the cutting blades, and each slitting mechanism 2 can be suitable for processing at least two specifications of the plate 3, and can be quickly switched as needed by rotating the slitting mechanism 2. Moreover, when each blade group 9 of the slitting mechanism 2 is not suitable for the specification of the plate 3 currently to be processed, the distance between the cutting blades on the blade shaft 14 can be adjusted as needed, which greatly improves the adaptability, does not need to increase the number of slitting mechanisms 2, and has a low cost.
[0046] As for the connection structure between the cutting blade 15 and the blade shaft 14, in this embodiment, the cutting blade 15 is sleeved on the blade shaft 14. At this time, the blade assembly 9 further includes fasteners, and each cutting blade 15 corresponds to two sets of fasteners. Along the axial direction of the blade shaft 14, the two sets of fasteners are respectively located on both sides of the cutting blade 15, and any fastener can be threadedly connected with any position of the blade shaft 14.
[0047] Specifically, an external thread can be provided on the cutter shaft 14, and the external thread extends from one end to the other end of the cutter shaft 14. A nut compatible with the external thread can be selected as a fastener, and the nut can be screwed to any position of the cutter shaft 14. By adjusting the position of the nut on the cutter shaft 14, the position of the cutting knife 15 can be adjusted.
[0048] Each set of fasteners may include two nuts. Two nuts are arranged on one side of the cutting knife 15. The double-nut locking principle is used to prevent the nuts from loosening, thereby ensuring that the position of the cutting knife 15 is stable.
[0049] In this embodiment, a storage section is provided at the end of the knife shaft 14, and any cutting knife 15 can be selectively fixed to the storage section. In specific use, the number of cutting knives 15 to be used and the spacing between the cutting knives 15 can be determined according to the specifications of the plate 3 to be processed, and the corresponding number of cutting knives 15 can be fixed to the knife shaft 14 according to the corresponding spacing, and the remaining cutting knives 15 can be fixed to the storage section of the knife shaft 14.
[0050] In this embodiment, the cutting edges of the cutting knives 15 of a pair of slitting mechanisms 2 are in opposite directions and both face the incoming side of the plate 3, which can ensure that the plate 3 enters between the pair of slitting mechanisms 2 against the cutting edge of the cutting knife 15, which is beneficial to improving the cutting quality of the anti-crack groove.
[0051] In this embodiment, the driving mechanism includes a first driving component 4 and a transmission component 5. The input end of the transmission component 5 is transmission-connected to the output end of the first driving component 4. The transmission component 5 has a pair of output ends that can rotate synchronously, and a pair of slitting mechanisms 2 are transmission-connected to the pair of output ends respectively.
[0052] In this way, by using the same driving mechanism to simultaneously drive a pair of slitting mechanisms 2 to rotate, the pair of slitting mechanisms 2 can be rotated synchronously relative to the support frame 1, so that the pair of slitting mechanisms 2 can be synchronously switched to the cutting position and can be synchronously switched to the retracting position, thereby ensuring the consistency of the retracting grooves on both sides of the plate 3, the length of the anti-crack grooves on both sides of the plate 3 is consistent, and the quality and aesthetics of the plate 3 are guaranteed.
[0053] The support frame 1 includes two columns and a crossbeam arranged between the two columns. A pair of slitting mechanisms 2 are arranged between the two columns, and a first driving assembly 4 and a transmission assembly 5 are arranged on the crossbeam.
[0054] In the embodiment of the utility model, the transmission assembly 5 includes a pair of racks 6 and a pair of gears 7 .
[0055] A pair of racks 6 are disposed on the support frame 1 , and the axes of the pair of racks 6 are parallel. The pair of racks 6 are relatively fixed, and the pair of racks 6 can slide back and forth relative to the support frame 1 .
[0056] A pair of gears 7 are rotatably arranged on the support frame 1 , and the rotation axes of the pair of gears 7 relative to the support frame 1 coincide with the rotation axes of the pair of slitting mechanisms 2 relative to the support frame 1 , respectively. Each slitting mechanism 2 is transmission-connected to a gear 7 .
[0057] The gear 7 is meshed with the rack 6 for transmission. When the pair of racks 6 slide relative to the support frame 1 , the pair of slitting mechanisms 2 can be driven to rotate synchronously relative to the support frame 1 through the pair of gears 7 .
[0058] In this embodiment, the tooth surfaces of the pair of racks 6 are arranged facing each other or away from each other. When the tooth surfaces of the pair of racks 6 are arranged facing each other, the pair of gears 7 are located between the pair of racks 6. When the tooth surfaces of the pair of racks 6 are arranged away from each other, the pair of gears 7 are located on both sides of the pair of racks 6.
[0059] With such arrangement, when the pair of racks 6 slide relative to the support frame 1, the pair of gears 7 rotate in opposite directions, and the pair of slitting mechanisms 2 rotate in opposite directions relative to the support frame 1. When the pair of slitting mechanisms rotate from the cutting position to the retracting position, the movement trend of the pair of slitting mechanisms 2 along the advancing direction of the plate 3 relative to the plate 3 is consistent, which can further ensure the consistency of the contact time between the pair of slitting structures and the plate 3, and can further improve the consistency of the structure of the retracting grooves on both sides of the plate 3.
[0060] In this embodiment, the first driving assembly 4 includes a first cylinder, the axis of the first cylinder is parallel to the axis of the rack 6, the cylinder barrel of the first cylinder is fixedly connected to the support frame 1, and the piston rod of the first cylinder is fixedly connected to the pair of racks 6. By controlling the telescopic action of the first cylinder, the pair of racks 6 can be driven to slide synchronously relative to the support frame 1, thereby driving the pair of gears 7 to rotate synchronously relative to the support frame 1, so that the pair of slitting mechanisms 2 rotate synchronously relative to the support frame 1.
[0061] A guide mechanism is also provided between the pair of racks 6 and the support frame 1 , and the guide mechanism is used to guide the sliding process of the racks 6 relative to the support frame 1 .
[0062] The guide mechanism can be, but is not limited to, a guide rail slider structure.
[0063] When processing the anti-crack groove, the first driving assembly 4 is used to drive a pair of slitting mechanisms 2 to rotate relative to the support frame 1 until the slitting mechanisms 2 rotate to one of the cutting positions, so that the target knife group 9 acts on the plate 3. Then the third driving assembly 10 corresponding to the knife group 9 is used to drive the knife group 9 to rotate relative to the rotating frame 8, so that the knife group 9 cuts the surface of the plate 3. The plate 3 moves forward relative to the anti-crack groove cutting device, and during the movement, a groove can be formed on the surface of the plate 3, which is called an anti-crack groove.
[0064] When each slitting mechanism 2 has at least two knife groups 9 and the first driving assembly 4 uses the first cylinder, the anti-crack groove cutting device further includes a limiting mechanism 16, which is arranged on the support frame 1 and is used to cooperate with the first driving assembly 4 to limit the rack 6 to different sliding positions. When the rack 6 is in different sliding positions, the slitting mechanism 2 is located at different cutting positions, that is, the knife groups 9 on the slitting mechanism 2 that act on the plate 3 are different. By changing the position of the rack 6 on the support frame 1, the knife group 9 that acts on the plate 3 can be switched.
[0065] In this embodiment, the limiting mechanism 16 includes a first limiting block 11 , a second limiting block 12 and a second driving assembly 13 .
[0066] The first limit block 11 is disposed at the output end of the first driving assembly 4 , and the first limit block 11 slides synchronously with the output end of the first driving assembly 4 relative to the support frame 1 .
[0067] The second limiting blocks 12 are reciprocatingly slidably disposed on the support frame 1 , and the number of the second limiting blocks 12 is consistent with the number of the knife groups 9 of each slitting mechanism 2 .
[0068] The second limiting block 12 can slide between the first position and the second position. Each second limiting block 12 is correspondingly provided with a second driving assembly 13, and the second driving assembly 13 is used to drive the second limiting block 12 to slide between the first position and the second position.
[0069] When the second limit block 12 slides to the first position, the second limit block 12 is located on the sliding track of the first limit block 11, and the second limit block 12 can be offset against the first limit block 11. Through the interaction between the second limit block 12 and the first limit block 11, the first cylinder can be limited from continuing to extend, so as to ensure the stability of the position of a pair of racks 6 on the support frame 1.
[0070] When the second limit block 12 slides to the second position, the second limit block 12 is located outside the sliding track of the first limit block 11, and the second limit block 12 cannot interfere with the first limit block 11, thereby removing the restriction on the telescopic movement of the first cylinder and allowing the first cylinder to perform telescopic movement as needed to drive the rack 6 to slide to the corresponding position.
[0071] Specifically, the sliding direction of the second limit block 12 relative to the support frame 1 is perpendicular to the sliding direction of the rack 6 relative to the support frame 1 .
[0072] The second driving assembly 13 includes a second cylinder, the axis direction of the second cylinder is perpendicular to the axis of the first cylinder. The cylinder barrel of the second cylinder is fixedly connected to the support frame 1, and the piston rod of the second cylinder is fixedly connected to the second limit block 12. The arrangement position of each second cylinder on the support frame 1 needs to ensure that when the first cylinder drives the slitting mechanism 2 to be located at different cutting positions, different second limit blocks 12 abut against the first limit block 11.
[0073] Reference Figure 5 Each slitting mechanism 2 includes four knife groups 9 and four third drive assemblies 10. The rotating frame 8 has a support shaft, and the axis of the support shaft coincides with the rotation axis of the rotating frame 8 relative to the support frame 1. The four knife groups 9 are evenly spaced along the circumference of the support shaft. Correspondingly, four second limit blocks 12 and four second drive assemblies 13 are also provided.
[0074] In this embodiment, the slitting mechanism 2 further includes a rotating frame 8 and a third driving assembly 10 .
[0075] The rotating frame 8 is rotatably connected to the support frame 1, and the rotating frame 8 is used to support the knife group 9 and the third driving assembly 10. The rotating frame 8 is in transmission connection with the above-mentioned gear 7, and the first driving assembly 4 can drive the rotating frame 8 to rotate relative to the support frame 1, thereby driving each knife group 9 and each third driving assembly 10 to rotate relative to the support frame 1, thereby switching the knife group 9 acting on the plate 3, and realizing the switching of the corresponding knife group 9 between the cutting position and the knife retracting position.
[0076] The axes of the knife shafts 14 of each knife group 9 are parallel to each other and are parallel to the axis of the gear 7. The knife shaft 14 is rotatably connected to the rotating frame 8, and the rotation axis of the knife shaft 14 relative to the rotating frame 8 coincides with the axis of the knife shaft 14. The end of the knife shaft 14 is transmission-connected to the third drive assembly 10, and the third drive assembly 10 can drive the knife shaft 14 to rotate relative to the rotating frame 8.
[0077] The third driving assembly 10 is disposed on the rotating frame 8 . One third driving assembly 10 is correspondingly disposed for each knife shaft 14 . The third driving assembly 10 is used for driving the knife shaft 14 to rotate relative to the rotating frame 8 .
[0078] The third driving assembly 10 can be, but is not limited to, a motor. Each knife shaft 14 is directly driven by an independent motor, and the knife shaft 14 drives the cutting knife 15 to rotate at a high speed, so as to achieve the cutting of the anti-crack groove.
[0079] On the other hand, the embodiment of the utility model further provides a plate production system, including the anti-crack groove cutting device provided in any of the above embodiments. The anti-crack groove cutting device provided in the above embodiments can ensure the consistency of the backing grooves on both sides of the plate 3, and ensure the quality and aesthetics of the plate 3. Therefore, the plate production system in this embodiment can process high-quality and beautiful plates 3. The derivation process of the beneficial effects of the plate production system in the embodiment of the utility model is generally similar to the derivation process of the beneficial effects of the above anti-crack groove cutting device, so it will not be repeated here.
[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
