Description

Technical Field

[0001] The present invention relates to the technical field of positioning mechanisms for sheet processing, and particularly to a positioning mechanism for building engineering sheet processing with high precision. Background Technique

[0002] During the processing of metal sheets used in construction engineering, due to different requirements for the sheets, shearing equipment is used to cut sheet-shaped or coiled metal sheets into strip-shaped or sheet-shaped metal plates. During this process, to ensure the precision of the dimensions of the metal plates or metal strips after shearing, a positioning mechanism is usually used to position the metal sheets to be sheared, such as the common limit plates for limiting the movement of metal sheets;

[0003] Currently, two or more limit plates for limiting the movement of metal sheets are used, and their limiting strength is mostly a fixed value. Different types of metal sheets will exhibit different stiffnesses due to different processing techniques or usage requirements, that is, there is a situation where the limiting strength of the limit plate on the metal sheet does not match the stiffness of the metal sheet itself. For example, when the limiting strength of the limit plate on the metal sheet is less than its own stiffness, the limiting effect of the limit plate on the metal sheet will be reduced. And if its limiting strength is greater than the stiffness of the metal sheet, when the metal sheet is displaced, the limit plate will squeeze the edge of the metal sheet, causing the edge of the metal sheet to bend and other situations, which easily reduces the final shearing effect of the metal sheet. Therefore, we propose a positioning mechanism for building engineering sheet processing with high precision to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems raised in the background technique, and to propose a positioning mechanism for building engineering sheet processing with high precision.

[0005] To achieve the above purpose, the present invention adopts the following technical solution:

[0006] A positioning mechanism for building engineering sheet processing with high precision, including an equipment main body and a sheet. A shearing component and a driving component are arranged on the equipment main body, and a resistance adjusting component is arranged on the equipment main body;

[0007] The driving component includes two sliding members installed through transmission components. Two support columns are fixedly installed on each of the two sliding members. Round rods are fixedly installed on the support columns. Rolling bearings are rotatably installed on the round rods. Limit plates are fixedly installed on the rolling bearings, and the limit plates are all made of lightweight materials. Linear uniformly distributed air blowing holes are opened on the limit plates. A correction component is jointly arranged between the support columns for automatically correcting the offset sheet;

[0008] The resistance adjusting assembly includes two telescopic rods fixedly installed on the equipment main body. Push members are fixedly installed on both of the two telescopic rods. A pre-tightening mechanism is jointly installed between the round rod and the two push members for automatically adjusting the limiting strength of the limiting plate according to the stiffness of the plate.

[0009] Compared with the prior art, the advantages of the present invention are as follows:

[0010] 1: When the equipment shears the plate, through the driving assembly, the distance between multiple limiting plates can be automatically adjusted according to the width of the plate to be sheared. At the same time, through the air supply assembly, the effect of multiple limiting plates cooperating to limit the movement of the plate can be further enhanced, which helps to improve the accuracy of the equipment for shearing the plate. At the same time, through the resistance adjusting assembly, the rotational resistance of multiple limiting plates, that is, the limiting strength of multiple limiting plates cooperating to limit the plate, can be automatically adjusted according to the stiffness of the plate itself, which can help to further improve the limiting effect of multiple limiting plates cooperating to limit the plate and help to improve the shearing effect of the equipment on the plate to a certain extent.

[0011] 2: When the position of the plate deviates under force and the resistance adjusting assembly drives multiple limiting plates to rotate and deviate together, through the cooperation of multiple limiting plates and the correction assembly, the position of the deviated plate can be corrected in time, which can help to improve the stability of the equipment for transmitting the position of the plate and the stability of the position to be sheared of the plate, and help to improve the accuracy of the equipment for shearing the plate.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figures 1 - 19 A high-precision positioning mechanism for processing construction engineering plates includes a device body 1 and a plate 2. The device body 1 is provided with a shearing component 3, the device body 1 is provided with a driving component 4, and the device body 1 is provided with a resistance adjustment component 5.

[0039] The plate 2 in the present invention specifically refers to a metal plate (in the form of a plate or a roll) made of stainless steel. The plate 2 can be sheared longitudinally (e.g. Figure 1 When the device is required to perform transverse shearing on the plate 2, the transverse shearing of the plate 2 can be achieved through the cooperation of the existing lifting device and the transverse shearing device on the device body 1. At the same time, the plate 2 can also be longitudinally sheared and transversely sheared in turn as needed. The specific shearing method can be selected according to the user's needs, which can help to improve the scope of application of the device.

[0040] Reference Figures 2 - 6 , Figure 11 , Figure 12The shearing assembly 3 includes a servo motor 31 fixedly mounted on the equipment body 1, a rotating shaft 32 is fixedly mounted on the driving end of the servo motor 31, a roller 33 is fixedly mounted on the rotating shaft 32, blades 34 uniformly distributed in a linear shape are fixedly mounted on the roller 33, and an air supply assembly 6 is arranged on the rotating shaft 32.

[0041] The air delivery component 6 includes two air collecting tubes 61 fixedly mounted on the rotating shaft 32. The two air collecting tubes 61 are each provided with arc-shaped openings evenly distributed in a ring shape, and a filter screen 62 is fixedly mounted on the arc-shaped openings. Two fans 65 are fixedly mounted on the rotating shaft 32, and the two fans 65 are both located in the corresponding air collecting tubes 61. An air delivery pipe 63 is fixedly connected between the two air collecting tubes 61 and the rotating roller 33. A plurality of exhaust ports 64 are provided on the rotating roller 33, and an air guide component is installed between the two air collecting tubes 61.

[0042] When the sheet 2 is conveyed by the existing conveying equipment to the bottom of the plurality of blades 34, the servo motor 31 is started. The operation of the servo motor 31 can drive the plurality of blades 34 to rotate at high speed to longitudinally shear the sheet 2 passing thereunder through the cooperation of the rotating shaft 32 and the roller 33, so as to achieve the effect of shearing the sheet 2 into a plurality of strip metal sheets as required (such as Figure 2 In the direction shown, from left to right of the plate 2 is the longitudinal direction of the plate 2).

[0043] At the same time, when the rotating shaft 32 is forced to drive the multiple blades 34 to rotate rapidly and perform longitudinal shearing on the plate 2 passing thereunder, the rotating shaft 32 will also drive the two fans 65 to rotate together, and suck the external gas into the two air collecting tubes 61 respectively. A small part of the gas entering the two air collecting tubes 61 will enter the inside of the roller 33 along the corresponding air supply pipes 63, and finally be discharged from the multiple exhaust ports 64 opened on the roller 33. The gas discharged from the corresponding multiple exhaust ports 64 can realize the cooling of the surface of the corresponding blade 34 by blowing, which can help to improve the temperature stability of the multiple blades 34 after continuously shearing the plate 2.

[0044] After the blade 34 continuously shears the sheet 2 under force, the blade 34 is easily affected by factors such as friction between it and the sheet 2, resulting in a continuous increase in its temperature. As the temperature of the blade 34 itself rises, the shearing temperature of the sheet 2 will also increase accordingly, which easily causes the hardness at the sheared edge of the sheet 2 to decrease and the plasticity to increase. At the same time, it is also easy to cause problems such as deformation at the cut of the sheet 2, an increase in burrs, and uneven edges, reducing the final shearing effect of the sheet 2. Moreover, during the transmission of the deformed sheet 2 by the existing conveying equipment, it is easy to increase the uneven frictional force between the sheet 2 and the existing conveying equipment, that is, it is easy to cause instability during the transmission speed of the sheet 2, and even jamming or deviation phenomena may occur. Therefore, through the above timely cooling treatment of the blade 34, not only can the continuous shearing effect of the equipment on the sheet 2 be improved to a certain extent, but also the stability of the equipment in transmitting the sheet 2 can be improved to a certain extent.

[0045] At the same time, through the cooperation of the corresponding multiple filter meshes 62, it can help improve the cleanliness of the gas entering the two air collecting cylinders 61, that is, it helps improve the cleanliness of the gas ejected from the multiple exhaust ports 64. Because the gas ejected from the corresponding multiple exhaust ports 64 can not only blow and dissipate heat on the surface of the corresponding blade 34, but also blow and clean the local surface of the sheet 2 passing through the lower exhaust port 64 (such as Figure 11 the direction shown), so as to effectively reduce the influence of dust and other impurities adhered to the surface of the sheet 2 on its final shearing effect.

[0046] Refer to Figures 1 - 8 、 Figures 11 - 14 As shown in FIGS., the driving assembly 4 includes two sliding members 46 installed through transmission components. Two support columns 47 are fixedly installed on both of the two sliding members 46. Round rods 48 are fixedly installed on the support columns 47. Rolling bearings 49 are rotatably installed on the round rods 48. Limit plates 410 are fixedly installed on the rolling bearings 49, and the limit plates 410 are all made of lightweight materials. Linear evenly distributed air blowing holes 411 are formed on the limit plates 410. A correction assembly 7 is jointly arranged between the support columns 47 for automatically correcting the offset sheet 2.

[0047] The transmission components include a support member 41 fixedly installed on the equipment main body 1. A motor 42 is fixedly installed on the support member 41. A rotating shaft 43 is fixedly installed at the driving end of the motor 42. A rotating rod 44 is rotatably installed on the support member 41. Reciprocating lead screws 45 are fixedly installed on both the rotating shaft 43 and the rotating rod 44, and the thread directions of the two reciprocating lead screws 45 are opposite. And the two reciprocating lead screws 45 are both connected to the corresponding sliding members 46 through ball nuts. Rotating wheels are fixedly installed on both the rotating shaft 43 and the rotating rod 44, and a conveyor belt (drawn in the figure but not labeled, which can be seen from Figure 5 it) is jointly sleeved and installed between the two rotating wheels.

[0048] The air guiding component includes rotating rings 66 respectively and rotatably mounted on two air collecting cylinders 61. The air collecting cylinders 61 are each provided with blowing ports (drawn but not labeled in the figure, visible from Figure 12 which can be seen). Two air guide pipes 67 are fixedly connected to both of the two rotating rings 66, and two exhaust pipes 68 are fixedly connected to both of the two air guide pipes 67.

[0049] During the process of the sheet 2 being transported and sheared, due to factors such as uneven self-tension of the sheet 2 (especially in the case of coiled sheets 2), uneven tool wear, and improper shearing speed, the sheet 2 is likely to shift in position during the transportation process, reducing the shearing effect of the equipment on the sheet 2.

[0050] Therefore, before the equipment starts to longitudinally shear the sheet 2, first start the motor 42. At this time, the motor 42 runs. Through the cooperation of two rotating wheels and the conveyor belt, when the rotating shaft 43 and the rotating rod 44 are driven to rotate forward together (at this time, multiple one-way bearings are in a rotatable state and will not rotate together), the two reciprocating lead screws 45 can be made to rotate together. Since the thread directions of the two reciprocating lead screws 45 are opposite, when the two reciprocating lead screws 45 rotate at this time, they will drive two sliding members 46 through the corresponding ball nuts to drive the corresponding two limiting plates 410 to approach each other until the distance between the two opposite limiting plates 410 is adapted to the width of the sheet 2 (as Figure 3 shown in the direction, from the left side to the right side of the sheet 2 is the width of the sheet 2). After that, during the process of the sheet 2 being transported and sheared, through the cooperation of multiple limiting plates 410, the movement limit of the sheet 2 can be achieved, that is, the movement positioning effect is achieved, which helps to improve the overall position stability of the sheet 2 during the subsequent shearing process and helps to improve the final shearing effect of the sheet 2.

[0051] At the same time, when the two fans 65 rotate continuously to inhale the outside air into the corresponding air collecting cylinders 61, most of the air inside the two air collecting cylinders 61 will flow into the corresponding rotating rings 66 through the corresponding blowing ports, and then along the corresponding air guide pipes 67, exhaust pipes 68, conical pipes 73, air conveying grooves on the support columns 47, and multiple round holes opened at the upper end of the round rod 48 (as Figure 8 shown), enter the corresponding limiting plates 410, and finally be blown towards the moving sheet 2 by the corresponding multiple air blowing holes 411. At this time, the impact force generated by the air blown out from the two opposite limiting plates 410 can not only further improve the stability of the movement limit of the sheet 2 by the cooperation of multiple limiting plates 410, but also use the air to blow and clean the upper and lower surfaces of the sheet 2, which can help to further improve the final shearing effect of the equipment on the sheet 2.

[0052] Meanwhile, during the transmission and shearing of the metal plate (referring to plate 2), a constant-strength positioning plate (referring to the limit plate 410) is commonly used to limit the movement of both sides of the metal plate. However, due to factors such as processing technology and processing requirements, the equipment main body 1 usually needs to shear metal plates with different stiffnesses. When the equipment needs to shear a metal plate with a lower stiffness, for example, longitudinally shear a 0.1-mm metal plate, and when the metal plate undergoes a position offset, if a positioning plate with a relatively large limit strength is selected to limit the metal plate, it is easy to cause damage such as indentation, deformation, or even cracking at the edge of the metal plate due to the extrusion of the metal plate offset on the positioning plate. Moreover, it may even prevent the shearing process from proceeding normally (such as when the metal plate continuously undergoes a position offset), reducing the final shearing effect and quality of the metal plate.

[0053] When the equipment shears a metal plate with a relatively large stiffness, if the limit strength of the selected positioning plate is relatively low, that is, less than the stiffness of the metal plate, when the metal plate undergoes a position offset and the extrusion force applied to the positioning plate is relatively large, it is easy to cause deformation of the positioning, which will not only reduce the service life of the positioning plate but also reduce the limit effect of the positioning plate on the metal plate.

[0054] The limit plate 410 is specifically made of lightweight materials such as carbon fiber composite materials. Through the extremely high specific strength and specific stiffness of the carbon fiber composite material itself, it can ensure that multiple limit plates 410 have sufficient strength and stiffness to limit the displacement of the plate 2. Through the relatively light characteristics of this material, it can effectively reduce the driving force required to drive the rotation of the limit plate 410. For example, when the equipment transmits and shears a plate 2 with a relatively thin thickness (such as a few tenths of a millimeter) and the plate 2 undergoes a position offset under the action of an external force, at this time, by applying a relatively low driving force to both sides of the limit plate 410 due to the force offset of the plate 2, multiple limit plates 410 can be driven to rotate and displace together. This can not only help improve the stability of the transmission of the plate 2 but also reduce the extrusion of the limit plate 410 on the edge of the plate 2 when the plate 2 undergoes a position offset, thus preventing the occurrence of bending.

[0055] At the same time, from Figure 8As can be seen, multiple limiting plates 410 are all hollow, and reinforcing plates are fixedly installed inside the limiting plates 410. The reinforcing plates can be specifically made of 6061 aluminum alloy material. Due to the advantages of 6061 aluminum alloy itself, such as small sealing, high strength, and light weight, not only can the stiffness of the corresponding limiting plates 410 be improved through the rib plates, that is, the limiting strength of the cooperation of the limiting plates 410 on the plate 2 can be increased, but also the overall quality of the limiting plates 410 can be ensured, that is, when the plate 2 has a position offset, the driving effect on the multiple limiting plates 410 can be ensured. In addition, only one rib plate is added inside the limiting plate 410 in the present invention. As the number of rib plates inside it increases, the stiffness and mass of the corresponding limiting plate 410 will also increase accordingly. Therefore, the specific number of reinforcing plates inside the limiting plate 410 can be freely selected according to factors such as the stiffness of the shearing plate 2 required by the equipment.

[0056] At the same time, rolling bearings 49 are provided between the limiting plates 410 and the corresponding round rods 48. The purpose is that when the plate 2 has a position offset and drives the multiple limiting plates 410 to rotate and displace with the corresponding round rods 48 as the axis, at this time, through the rolling bearings 49, the rotational resistance of the corresponding round rods 48 to the limiting plates 410 can be effectively reduced indirectly. In this way, it can be ensured that even when the stiffness of the plate 2 decreases and the driving force generated by its offset is low, the effect of driving the multiple limiting plates 410 to rotate and offset can still be achieved. Because the rolling friction generated between the rolling bearings 49 and the corresponding round rods 48 is much smaller than the sliding friction of the limiting plates 410 directly contacting the round rods 48, when the limiting plates 410 are subjected to the driving force of the displacement offset of the plate 2, they can rotate around the round rods 48 more easily. In addition, the rolling bearings 49 have high rotational accuracy and stability, which can ensure that the limiting plates 410 rotate more smoothly and accurately around the corresponding round rods 48. In this way, it can be ensured that when the plate 2 is slightly offset under force, the limiting plates 410 can also accurately follow the plate 2 to perform a small rotational offset effect. In this way, it can be ensured that when the plate 2 has a small offset, the multiple limiting plates 410 cooperate with the correction assembly 7 to correct the offset plate 2 in a timely manner.

[0057] Refer to Figures 6 - 10 , the resistance adjustment assembly 5 includes two telescopic rods 52 fixedly installed on the equipment main body 1. Push members 53 are fixedly installed on both telescopic rods 52. A pre-tightening mechanism is installed between the round rod 48 and the two push members 53, which is used to automatically adjust the limiting strength of the limiting plates 410 according to the stiffness of the plate 2.

[0058] The pre-tightening mechanism includes two connecting rods 54 respectively and fixedly installed on two pushing members 53. A plurality of position-limiting plates are fixedly installed on the equipment main body 1, and the position-limiting plates are all used for limiting the movement of the corresponding connecting rod 54. First racks 55 are fixedly installed at the lower ends of the connecting rods 54. Driving discs 412 are rotatably installed on the round rods 48. Torsion springs 413 are fixedly installed between the driving discs 412 and the corresponding limiting plates 410. Rotating gears 414 meshing with the corresponding first racks 55 are fixedly installed on the driving discs 412. Two inclined blocks 51 are installed on the rotating shaft 43 and the rotating rod 44 through two one-way bearings, and the corresponding two inclined blocks 51 are all matched with the corresponding pushing members 53.

[0059] When the equipment transports the plate 2, according to Newton's second law F = ma (where F is force, m is mass, and a is acceleration), at the same acceleration, the greater the mass of the plate 2 (since the mass of the plate 2 is usually positively correlated with its stiffness, when the mass of the plate 2 increases, its own stiffness usually also increases), the greater the driving force generated when it is deflected by force.

[0060] At the same time, the initial pre-tightening force of the torsion spring 413 is set to be relatively low, that is, only a small rotational force needs to be applied to it in the initial state to drive the torsion spring 413 to twist. The purpose is to ensure that when the equipment main body 1 transports the plate 2 with relatively low stiffness, and the plate 2 is displaced due to force, when driving a plurality of limiting plates 410 to start rotating and displacing, the rotational resistance generated by the corresponding torsion spring 413 on the limiting plates 410 is relatively small. The purpose is to ensure that when the driving force generated by the offset of the plate 2 is small due to its relatively low stiffness, the effect of still being able to drive a plurality of limiting plates 410 to rotate and displace can be achieved.

[0061] At the same time, when the plate 2 is displaced and drives a plurality of limiting plates 410 to offset and rotate, one end of the corresponding torsion spring 413 will rotate along with it, that is, the torsion spring 413 is caused to twist. According to Hooke's law, when the torsion spring 413 is twisted, a torsion force that hinders the rotation of the corresponding limiting plate 410, also called a restoring force, will be generated. This torsion force will act on the plate 2 through the corresponding limiting plate 410, so as to apply a certain deflection resistance to the plate 2, that is, to hinder the continuous offset of the plate 2 to a certain extent, which helps to reduce the angle of displacement offset of the plate 2 due to force per unit time to a certain extent, and helps to further improve the timeliness of correcting the offset plate 2 by the subsequent cooperation of a plurality of limiting plates 410 and the correcting assembly 7.

[0062] Meanwhile, when the quality, i.e., stiffness, of the to-be-sheared sheet 2 increases, before adjusting the positions of the multiple limiting plates 410, the motor 42 is reversely started. At this time, the operation of the motor 42 can drive the multiple inclined blocks 51 to rotate through the cooperation of the rotating shaft 43, the rotating rod 44, and the multiple one-way bearings. When the corresponding two inclined blocks 51 rotate in cooperation, a rightward thrust will be applied to the corresponding pushing member 53 (as shown in the direction of Figure 9 ), and when the pushing member 53 drives the corresponding two connecting rods 54 and two first racks 55 to move rightward under force (as shown in the direction of Figure 9 ), the first rack 55 can drive the driving disk 412 to drive the corresponding torsion spring 413 to rotate and pre-tighten through cooperation with the corresponding rotating gear 414 (the driving force required to drive the driving disk 412 is set to be relatively large, and only when the corresponding first rack 55 cooperates with the rotating gear 414 can the driving disk 412 be driven to rotate. When the sheet 2 drives the limiting plate 410 to rotate, the driving force exerted by the limiting plate 410 on the driving disk 412 through the corresponding torsion spring 413 cannot drive it to rotate. And in the initial state, the corresponding two correction plates 711 cooperate to limit the positions of the adjusting rod 72 and the limiting plate 410. When the driving disk 412 drives the corresponding torsion spring 413 to rotate, the corresponding limiting plate 410 will not rotate along with it).

[0063] As the driving disk 412 drives the corresponding torsion spring 413 to continuously rotate under force, the initial pre-tightening force of the torsion spring 413, i.e., the initial torque, will also continuously increase. At this time, if the sheet 2 deflects and drives the limiting plate 410 to rotate, the resistance that the limiting plate 410 needs to overcome during rotation is the sum of the initial torque of the torsion spring 413 and the torque generated during the rotation of the limiting plate 410 driven by it. Therefore, as the initial torque of the torsion spring 413 increases, the resistance that the limiting plate 410 needs to overcome when rotating under force will also increase correspondingly, that is, the rotation resistance of the sheet 2 driving the limiting plate 410 will also increase. In this way, it can be realized that according to the increase in the stiffness of the sheet 2, the rotation resistance of the multiple limiting plates 410 is automatically adjusted, that is, the adaptability of the multiple limiting plates 410 to cooperate with the limiting strength of the sheet 2 is increased.

[0064] Meanwhile, when it is necessary to transmit and shear the sheet 2 with a lower stiffness, during the process of driving the two pushing members 53 to move leftward and reset (as shown in the direction of Figure 9 ) by the operation of the motor 42, through the cooperation of the multiple first racks 55 with the corresponding rotating gears 414 and the driving disk 412, the initial pre-tightening force of the corresponding torsion spring 413 can be gradually reduced, so as to ensure the effect that the initial rotation resistance of the corresponding limiting plate 410, i.e., the limiting strength, is adapted to the stiffness of the to-be-sheared sheet 2. In this way, it can not only help to improve the limiting effect of the multiple limiting plates 410 on the movement of the sheet 2, but also reduce the situation of the limiting plate 410 squeezing the edge of the sheet 2 when the sheet 2 is displaced.

[0065] Reference Figures 11 - 19 , the correction component 7 includes discs 71 respectively and fixedly installed on the support columns 47, and one end of each exhaust pipe 68 penetrates through and is fixedly installed on the corresponding disc 71. The lower ends of the limiting plates 410 are fixedly installed with adjusting rods 72 respectively. The adjusting rods 72 penetrate through and are fixedly installed with conical tubes 73 respectively. Air delivery grooves (drawn but not labeled in the figure, visible from Figure 14 ) are formed on the support columns 47 respectively, and the air delivery grooves communicate with the corresponding round rods 48 respectively. Sealing plates 74 are fixedly installed on the air delivery grooves respectively (in the state shown in Figure 16 , the left sides of the corresponding air delivery grooves can be blocked by the sealing plates 74, so that a sealed space is formed inside the air delivery grooves), limiting rods 75 are fixedly installed on the air delivery grooves respectively, and sealing plates 77 are hermetically and slidably installed between the limiting rods 75 and the corresponding air delivery grooves respectively. A return spring 76 is fixedly installed between each sealing plate 77 and the corresponding air delivery groove. An adjusting component is installed between the support columns 47 together.

[0066] The adjusting component includes two support rings 710 respectively and rotatably installed on the support columns 47. Correction plates 711 are fixedly installed on the support rings 710 respectively. Parallel shaft gears 712 are fixedly installed on the support rings 710 respectively. Two elastic membranes 79 are fixedly installed on the air delivery grooves respectively, and the sealing plates 77 are hermetically and slidably installed between the corresponding two elastic membranes 79 respectively. Two connecting pieces 78 are fixedly installed on each sealing plate 77 respectively, and the connecting pieces 78 penetrate through and are fixedly installed on the corresponding elastic membranes 79 hermetically respectively. Second racks 713 meshing with the corresponding parallel shaft gears 712 are fixedly installed on the connecting pieces 78 respectively.

[0067] As shown in Figure 16 , air inlet holes adapted to the outer diameters of the right ends of the corresponding conical tubes 73 are formed on the sealing plates 74, and in the initial state, the left ends of the conical tubes 73 are directly opposite to the corresponding exhaust pipes 68 respectively (in the direction shown in Figure 15 ), and the right ends of the conical tubes 73 are directly opposite to the air inlet holes formed on the corresponding sealing plates 74 respectively. In this way, it can be ensured that in the initial state, after the outside air is input into the multiple exhaust pipes 68 through the cooperation of the above-mentioned air delivery component 6 and the air guiding component, the air inside the multiple exhaust pipes 68 can enter the corresponding air delivery grooves along the corresponding conical tubes 73.

[0068] After the air is input into the corresponding air delivery grooves through the cooperation of the corresponding air collecting cylinders 61, rotating rings 66, air guiding pipes 67, exhaust pipes 68 and conical tubes 73, this part of the air will first gather on the left side of the corresponding sealing plates 77 (as shown in Figure 16In the shown direction), as the gas accumulating on the left side of the sealing plate 77 continuously increases, the thrust applied to the corresponding sealing plate 77 towards the right is greater than the sum of the maximum static friction of the corresponding sealing plate 77 and its component assemblies thereon and the elastic force of the corresponding return spring 76. At this time, the gas accumulating on the right side of the sealing plate 77 will push it to move towards the right, and as Figure 14 shown, the air ducts opened on the support column 47 are all T-shaped ducts. When the sealing plate 77 moves under force to the middle part of the corresponding air duct, part of the gas accumulating on the right side of the corresponding sealing plate 77 will enter the corresponding round rod 48 along the corresponding air duct and be blown into the corresponding limiting plate 410 from the multiple round holes opened at the upper end of the round rod 48.

[0069] Meanwhile, according to the above description, during the process of the sealing plate 77 moving towards the right under force, through the cooperation of the corresponding air duct wall, limiting rod 75, two elastic membranes 79 and the return spring 76, the movement of the sealing plate 77 can be limited, which helps to improve the stability of the sealing plate 77 driving its component assemblies thereon to move under force. And when the sealing plate 77 drives the corresponding two connecting pieces 78 to move towards the right under force, at this time, through the extrusion of the corresponding elastic membrane 79 by the connecting piece 78, the airtightness inside the air duct can be ensured at this stage.

[0070] Meanwhile, in the initial state, when the driving force generated by the gas drives the sealing plate 77 to drive the corresponding connecting piece 78 and the second rack 713 to move towards the right (in the Figure 18 shown direction), at this time, through the cooperation of the second rack 713 and the corresponding parallel shaft gear 712, the corresponding support ring 710 can be driven to drive the corresponding correction plate 711 to rotate. And since the corresponding two second racks 713 are arranged oppositely, the corresponding two second racks 713 cooperate under force to drive the corresponding two support rings 710 to rotate in opposite directions, that is, at this time, the corresponding two support rings 710 will drive the corresponding two correction plates 711 to rotate away from each other under force. After the corresponding two correction plates 711 rotate away from the corresponding adjusting rod 72 under force, it can ensure that when the subsequent limiting plate 410 cooperates to limit the sheet 2 and the sheet 2 is displaced under force, the effect of driving the limiting plate 410 and the corresponding adjusting rod 72 to rotate together. That is, during the process of the equipment transporting and shearing the sheet 2, when the corresponding two correction plates 711 cooperate to continuously fix the positions of the adjusting rod 72 and the limiting plate 410, it will make the initial stiffness of the limiting plate 410 too large, and the effect of adjusting the limiting stiffness of the limiting plate 410 according to the stiffness of the sheet 2 to be sheared cannot be achieved, nor can the effect of correcting the position of the offset sheet 2 through the cooperation of multiple limiting plates 410 and the correction assembly 7 be achieved.

[0071] And when the sheet 2 is displaced under force to drive the limiting plate 410 and the adjusting rod 72 to rotate around the corresponding round rod 48 as the axis (in the Figure 18In the direction shown), at this time, the adjusting rod 72 will drive the corresponding conical tube 73 to rotate together. When the left end of the conical tube 73 is offset from the position of the corresponding exhaust pipe 68 (the left end of the conical tube 73 and the right end of the corresponding exhaust pipe 68 are both designed with matching arc surfaces, so as to effectively reduce the wear between the two when the conical tube 73 is displaced relative to the exhaust pipe 68), and when its right end is offset from the air inlet hole on the corresponding sealing plate 74, that is, when the amount of gas entering the corresponding air delivery groove and the left side of the sealing plate 77 decreases at this time, under the action of the self-elastic force of the corresponding return spring 76, the sealing plate 77 can be driven to drive the corresponding two connecting pieces 78 and two second racks 713 to quickly move to the left to reset (as Figure 15 In the direction shown). During this process, through the cooperation of the corresponding two second racks 713 with the corresponding parallel shaft gears 712 and the support ring 710, the corresponding two correction plates 711 can be driven to rotate and reset. During the rotation and reset process of the two correction plates 711, a reverse driving force can be applied to the corresponding adjusting rod 72, that is, a rotational reset driving force can be applied to the plate 2 through the adjusting rod 72 and the corresponding limiting plate 410, so as to achieve the effect of automatically correcting the offset plate 2 (at the same time, the correction plates 711 that can rotate relative to the force are set to facilitate the driving force for moving and resetting through the corresponding two correction plates 711 when the limiting plate 410 drives the corresponding adjusting rod 72 to rotate clockwise or counterclockwise under force, so as to achieve the effect of moving and correcting its deviation).

[0072] The reverse driving forces applied to the corresponding adjusting rod 72 and the limiting plate 410 by the corresponding two correction plates 711 are always greater than the driving forces applied to the limiting plate 410 and the adjusting rod 72 by the plate 2 due to force offset. The purpose is to ensure that when the plate 2 is displaced due to force during the transmission and shearing process, and when multiple limiting plates 410 and the adjusting rod 72 rotate together, the positions of the plate 2, multiple limiting plates 410, and the adjusting rod 72 can be corrected in time through the cooperation of multiple correction plates 711 and the correction assembly 7.

[0073] At the same time, the right end diameters of multiple conical tubes 73 are all smaller (such as Figure 16In the shown direction, the air inlet holes formed in multiple blocking plates 74 and adapted to the right ends of the corresponding conical pipes 73 also have a relatively small aperture. The purpose is that when the sheet material 2 is driven by force to make the limiting plate 410 and the adjusting rod 72 rotate by a small angle, due to the relatively small output pipe diameter of the conical pipe 73 and the relatively small aperture of the air inlet hole on the blocking plate 74, the positions of the two will shift. When the corresponding conical pipe 73 stops supplying gas to the corresponding air delivery groove and the gas inside it continuously flows out, at this time, under the action of the self-elastic force of the corresponding return spring 76 and the above operating principle, the corresponding two correcting plates 711 can quickly rotate and reset, applying a reverse force to the corresponding adjusting rod 72 and the limiting plate 410, that is, driving multiple limiting plates 410 to cooperate to correct the position of the sheet material 2, which can help to further improve the timeliness of the equipment to correct the offset sheet material 2, and help to further improve the stability of the shearing position of the sheet material 2 during the transmission process, as well as the final shearing effect of the sheet material 2 when it is sheared.

[0074] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0075] In the present invention, when the equipment needs to shear the sheet material 2, the driving assembly 4 can first adjust the positions of multiple limiting plates 410 according to the width of the sheet material 2. Then, through the cooperation of multiple limiting plates 410, the transmission and positioning of the sheet material 2 can be realized, which helps to improve the stability of the position of the sheet material 2 during the transmission and shearing process. At the same time, when multiple limiting plates 410 cooperate to limit the movement of the sheet material 2, through the air delivery assembly 6, multiple limiting plates 410 can cooperate to blow air on both sides of the sheet material 2. This can not only help to further increase the effect of multiple limiting plates 410 cooperating to limit the movement of the sheet material 2, but also blow and clean the impurities on the upper and lower sides of the sheet material 2, which helps to improve the shearing effect of the equipment on the sheet material 2.

[0076] At the same time, through the resistance adjusting assembly 5, the effect of indirectly adjusting the limiting strength of multiple limiting plates 410 cooperating to limit the sheet material 2 according to the stiffness of the sheet material 2 to be sheared can be realized, which can help to further improve the effect of multiple limiting plates 410 cooperating to limit the movement of the sheet material 2.

[0077] If the sheet material 2 drives the limiting plate 410 to shift in position during the transmission and shearing process, at this time, through the cooperation of the corresponding two correcting plates 711 and the correcting assembly 7, a reverse force can be applied to multiple limiting plates 410, so that multiple limiting plates 410 cooperate to drive the sheet material 2 to rotate and reset. In this way, when the sheet material 2 shifts in position, the effect of timely correction can be realized, which helps to further ensure the stability of the position of the sheet material 2 to be sheared and the final shearing effect of the sheet material 2 when the equipment shears the sheet material 2.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
