Description
TECHNICAL FIELD
[0001] The utility model belongs to long section bar processing equipment field, concretely relates to a long section bar conveying unit and processing conveying line. BACKGROUND
[0002] In the modern industrial processing field, H-shaped steel is widely used in construction, machinery manufacturing and many other industries due to its unique structure and good mechanical properties. And with the continuous improvement of the manufacturing industry's requirements for processing precision and efficiency, laser cutting technology is increasingly used in H-shaped steel processing.
[0003] At present, the conveying principle of the existing H-shaped steel conveying line is mainly to rely on the contact with the wing plate of the H-shaped steel to realize the conveying. And during the conveying process, the conveying components such as rollers and conveyor belts need to be closely attached to the wing plate of the H-shaped steel, so as to drive the H-shaped steel to move forward through friction. Therefore, this conveying method is commonly used in general processing scenarios of H-shaped steel, such as simple surface treatment and ordinary welding processing of H-shaped steel, and to some extent, it meets the production needs of conventional H-shaped steel processing enterprises.
[0004] However, when it comes to the production line of cutting H-shaped steel into T-shaped steel, the existing conveying line has obvious limitations. Specifically, in the processing of cutting H-shaped steel into T-shaped steel, the web of the H-shaped steel needs to be cut. If the existing conveying method of contacting the wing plate is used, the H-shaped steel is prone to vibration and deformation during cutting due to the lack of effective support of the web, which seriously affects the cutting precision, resulting in large size deviation of the cut T-shaped steel, and cannot meet the high-quality processing requirements. And in the cutting process, the conveying components in contact with the wing plate may interfere with the normal operation of the cutting equipment, increasing the risk of equipment failure. UTILITY MODEL CONTENTS
[0005] The utility model aims at the problem that the existing H-shaped steel conveying line cannot meet the H-shaped steel conveying requirements in the production line of cutting H-shaped steel into T-shaped steel, and proposes and designs a new long section bar conveying unit and processing conveying line to meet this special processing demand and ensure product processing precision.
[0006] To achieve the above objectives, on the one hand, this utility model provides a long profile conveying unit, which includes two parallel support frames and a material conveying channel between the two support frames; each support frame is provided with a drive roller group, and each drive roller group is driven by a rotary drive mechanism. Each drive roller group includes at least two drive rollers arranged parallel to each other along the material conveying direction. The middle part of the drive roller is rotatably mounted on the corresponding support frame. One end of the drive roller extends into the material conveying channel and is provided with a support roller, and the other end of the drive roller extends out of the support frame and is driven by the rotary drive mechanism; the drive rollers of the two drive roller groups are arranged opposite each other, and a clearance gap is provided between the two opposite support rollers. At this point, on the one hand, this invention can constrain the travel direction of the H-beam through the cooperation of two support frames and the flanges on both sides of the H-beam, preventing the H-beam from deviating; the support roller structure supports the web of the H-beam, ensuring stable support for the long profile during transportation, thereby avoiding sagging and deformation caused by gravity; on the other hand, this invention can provide sufficient and uniform driving force through two parallel transmission roller groups and the two rotary drive mechanisms connected to them, ensuring uniform speed transportation of the profile and reducing jamming, and the clearance between the support rollers can reserve operating space for processing steps, facilitating cutting, welding and other processing, ensuring that the H-beam can be smoothly cut into T-beams; at the same time, the two-end arrangement of the transmission rollers in this invention can also separate the transmission and support functions, optimizing the overall structure.
[0007] Furthermore, at least one guiding mechanism is provided on the side of the support frame facing the material conveying channel. This guiding mechanism guides the materials, such as H-beams, during their movement to ensure that the materials always travel in a straight line along the preset route, thereby ensuring that the materials can move smoothly along the conveyor line and avoiding jamming during the conveying process.

Moreover, the spring is sleeved on the guide column, which can absorb the impact force by elastic deformation when the guide plate is pressed by the material, thereby ensuring the stable work of the guide plate; on the other hand, the guide plate can be quickly reset by the elastic force of the spring after the material passes, so as to prepare for the next guiding and ensure that the profile always maintains a stable and accurate conveying path on the conveying line, thereby improving the conveying efficiency and processing precision.
[0009] Further, the guide plate comprises a guide inclined surface part one, a flat part and a guide inclined surface part two which are sequentially arranged along the material advancing direction, the flat part is a vertical surface parallel to the material advancing direction, the guide inclined surface part one gradually inclines towards the fixed sleeve in the direction opposite to the material advancing direction, and the guide inclined surface part two gradually inclines towards the fixed sleeve along the material advancing direction. At this time, when the long profile passes through the guide mechanism during the advancing process, it will first contact the guide inclined surface part one and gradually approach the center position of the material conveying channel under the guiding action of the guide inclined surface part one, thereby preliminarily calibrating the initial position of the long profile and reducing the unstable conveying caused by the placement deviation; then the long profile will contact the flat part after the preliminary guiding of the guide inclined surface part one; the flat part can limit the long profile, thereby ensuring that the long profile maintains a vertical state during conveying and cannot shake left and right or incline, so that the long profile can advance along the conveying direction in a stable posture. Conversely, when the workpiece needs to be retreated, the long profile can be preliminarily guided by the guide inclined surface part two and then limited by the flat part.
[0010] Further, the long profile conveying unit is provided with at least one horizontal pressing mechanism along the material conveying direction, and the material is subjected to horizontal pressing treatment by the horizontal pressing mechanism to realize the transverse fixation of the material, thereby ensuring that the material can meet the material processing precision requirement.
[0011] Further, the horizontal pressing mechanism comprises a mounting seat one and a mounting seat two, the mounting seat one and the mounting seat two are respectively installed on the two support frames; the horizontal rotating wheel one is rotatably installed on the mounting seat one, the horizontal linear motion executing element one is installed on the mounting seat two, the output end of the horizontal linear motion executing element one is provided with a horizontal top plate, the horizontal rotating wheel two is rotatably installed on the horizontal top plate, the horizontal rotating wheel two is oppositely arranged with the corresponding horizontal rotating wheel one, and the horizontal rotating wheel two can approach or move away from the horizontal rotating wheel one under the action of the horizontal linear motion executing element one, so as to realize the corresponding horizontal pressing action or relaxation action.
[0012] Further, the long profile conveying unit is provided with at least one vertical pressing mechanism along the material conveying direction, and the vertical pressing mechanism is used for vertically pressing the material, so as to realize vertical fixation of the material and ensure that the material can meet the material processing precision requirement.

[0014] Further, two material guiding slopes one are symmetrically arranged at the left and right sides of the feeding end of the material conveying channel, and the two material guiding slopes one gradually incline inward along the material advancing direction. At this time, the feeding end of the material conveying channel forms a horn mouth type feeding port structure with a gradually reduced caliber along the feeding direction under the action of the two material guiding slopes, and based on the horn mouth, on the one hand, the material profile and other materials can enter the feeding area without special accurate positioning when being initially placed, and even if there is a slight deviation, the material profile and other materials can also enter the feeding area along the wide opening, so that the feeding difficulty is greatly reduced, and the operation efficiency is improved; on the other hand, as the material profile and other materials advance, the horn shape structure which is gradually closed can gather the material profile and other materials, gradually guide the material profile to the accurate position, so that the material profile accurately and correctly advances on the conveying line, thereby effectively avoiding the problems of conveying jamming and equipment collision of the material profile due to position deviation in the conveying process, and ensuring the stability and smoothness of the conveying process. Meanwhile, the unique shape design can also adapt to different specifications of the material profile, whether the material profile is wide or narrow, the horn shape feeding port structure can be used for smooth feeding, and the compatibility of the whole conveying line to various material profiles is enhanced, and the application range of the equipment is widened.

DETAILED DESCRIPTION
[0026] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model will be described clearly and completely in the following by combining the drawings in the specific embodiment. Obviously, the following described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the patent, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the patent protection.
[0027] Embodiment one
[0028] As Figures 1 to 6As shown, the first embodiment provides a long profile conveying unit, which comprises two parallel support frames 4, and a material conveying channel 9 is arranged between the two support frames 4 for conveying materials. Two material guide slopes 2 are symmetrically arranged on the left and right sides of the feeding end of the material conveying channel 9. The two material guide slopes 2 are gradually inclined inward along the material advancing direction, and form a horn-shaped feeding port structure with a gradually reduced diameter along the feeding direction at the feeding end of the material conveying channel 9. Based on the horn-shaped structure, on the one hand, the first embodiment can greatly improve the fault tolerance of feeding, so that the long profiles and other materials do not need to be positioned particularly accurately when they are initially placed. Even if there is a slight deviation in position, they can still enter the feeding area along the wide opening, thereby greatly reducing the feeding difficulty and improving the operation efficiency. On the other hand, as the long profiles and other materials advance, the first embodiment can play a gathering role through the gradually converging horn-shaped structure, gradually guide the profiles to the accurate position, and make them accurately advance on the conveying line, thereby effectively avoiding problems such as conveying jamming and equipment collision of the profiles in the conveying process due to position deviation, and ensuring the stability and smoothness of the conveying process. At the same time, this unique shape design can also adapt to long profiles of different specifications. Whether the profiles are wide or narrow, they can be smoothly fed by means of the horn-shaped feeding port structure, thereby enhancing the compatibility of the entire conveying line for various profiles and widening the application range of the equipment. In addition, as a preferred embodiment, the first embodiment is also provided with a material guide slope 3 at the lower part of the feeding end of the material conveying channel 9, and the material guide slope 3 is gradually inclined downward in the direction opposite to the material advancing direction. In this way, by means of the height difference of the material guide slope 3, the speed of the material entering the conveying line is cleverly slowed down, avoiding the strong collision between the material and the conveying equipment due to the too fast entry of the material, and ensuring the safe and stable operation of the conveying line.
[0029] Each support frame 4 is provided with a transmission roller set, and each transmission roller set is drivingly connected with a rotary driving mechanism 5. Specifically, each transmission roller set comprises at least two transmission rollers 31 arranged in parallel along the material conveying direction. The middle part of each transmission roller 31 is rotatably installed on the corresponding support frame 4 through a bearing or the like. One end of each transmission roller 31 extends into the material conveying channel 9 and is provided with a supporting roller 32, which is in contact with and supports the conveyed material to realize the corresponding conveying function. When the material is an H-shaped steel, the supporting roller 32 directly contacts the web of the H-shaped steel. The other end of each transmission roller 31 extends out of the support frame 4 and is drivingly connected with the rotary driving mechanism 5. The rotary driving mechanism 5 can adopt a combination of a driving motor and a chain transmission mechanism, i.e., it can adopt a structure in which the driving motor is drivingly connected with any one of the transmission rollers 31 of the corresponding transmission roller set, and all other transmission rollers 31 are drivingly connected together through the chain transmission mechanism.
[0030] Meanwhile, in the process of arranging the two transmission roller groups, in order to ensure the stability of the movement of the material, the embodiment one needs to arrange the transmission rollers 31 in the two transmission roller groups oppositely, and leave a gap 33 between the two opposite supporting rollers 32. At this time, on the one hand, the embodiment one can constrain the advancing direction of the H-shaped steel through the cooperation of the two supporting frames 4 and the two side flanges of the H-shaped steel, so as to avoid the deviation of the H-shaped steel; the web of the H-shaped steel is supported by the supporting roller structure, so as to ensure the stable support of the long profile during the conveying process, thereby avoiding the sagging and deformation caused by gravity; on the other hand, the embodiment one can provide sufficient and uniform driving force through the two parallel transmission roller groups and the two rotary driving mechanisms 5 connected by the transmission, so as to ensure the uniform conveying of the profile, reduce the jamming, and also reserve the operation space for the machining process through the gap 33 between the supporting rollers 32, so as to facilitate the cutting, welding and other machining, and ensure that the H-shaped steel can be smoothly cut into T-shaped steel.
[0031] In addition, in order to ensure the machining precision of the H-shaped steel and other materials, the embodiment one also arranges a plurality of vertical pressing mechanisms 8 on the two supporting frames 4 of the long profile conveying unit, and a plurality of horizontal pressing mechanisms 11 between the two supporting frames 4 of the long profile conveying unit.
[0032] Specifically, as shown in Figure 4 , the vertical pressing mechanism 8 comprises a mounting seat three 26, the mounting seat three 26 is installed on any one supporting frame 4, and the upper end of the mounting seat three 26 is provided with a horizontal linear motion executing element two 22, and the output motion direction of the horizontal linear motion executing element two 22 is perpendicular to the material conveying direction. The output end of the horizontal linear motion executing element two 22 is installed with a vertical linear motion executing element 25 through a support 23, and a vertical pressing plate 27 is installed at the output end of the vertical linear motion executing element 25, and a universal wheel 24 is arranged at the lower end of the vertical pressing plate 27. In this way, during the conveying of the H-shaped steel and other materials, the embodiment one can prevent the deformation and misalignment of the H-shaped steel after cutting by vertically pressing the H-shaped steel and other materials through the vertical pressing mechanism 8; on the other hand, the vertical linear motion executing element 25 and the components installed at the vertical linear motion executing element 25 can be controlled to avoid affecting the cutting operation of the H-shaped steel and other materials through the horizontal linear motion executing element two 22.
[0033] As shown in Figure 2 , Figure 3As shown, the horizontal pressing mechanism 11 comprises a mounting seat one 12 and a mounting seat two 6, which are respectively mounted on the two support frames 4 of the long profile conveying unit. Moreover, the horizontal rotating wheel one 13 is rotatably mounted on the mounting seat one 12, and the horizontal linear motion executing element one 28 is fixedly mounted on the mounting seat two 6, and the output motion direction of the horizontal linear motion executing element one 28 is perpendicular to the material conveying direction. Meanwhile, the output end of the horizontal linear motion executing element one 28 is provided with the horizontal top plate 29, the horizontal rotating wheel two 30 is rotatably mounted on the horizontal top plate 29, and the horizontal rotating wheel two 30 is oppositely arranged with the corresponding horizontal rotating wheel one 13, so that the horizontal rotating wheel two 30 can approach or move away from the horizontal rotating wheel one 13 under the action of the horizontal linear motion executing element one 28, so as to realize the corresponding horizontal pressing action or relaxation action, so as to enable it to horizontally press the H-shaped steel and other materials during the conveying process of the H-shaped steel and other materials.
[0034] In addition, the embodiment one is also provided with at least one guide mechanism 7 on any one of the support frames 4 of the long profile conveying unit, and when the number of the guide mechanisms 7 is 2 or more, all the guide mechanisms 7 can be uniformly spaced and arranged in parallel on the side of the corresponding support frame 4, so as to guide the material during the material advancing process through the guide mechanism 7, so as to ensure that the material can always linearly advance along the preset route, thereby ensuring that the material can smoothly advance along the conveying line, avoiding the phenomenon of jamming during the conveying process. Specifically, as shown in the figure, Figure 5 As shown, the guide mechanism 7 comprises the fixed sleeve 15 fixedly mounted in the support frame 4, the guide column 14 is inserted in the fixed sleeve 15, and the flange edge 18 is arranged at one end of the guide column 14 extending out of the fixed sleeve 15, the flange edge 18 is located in the support frame 4 and can abut against the fixed sleeve 15; the other end of the guide column 14 extending out of the fixed sleeve 15 is located in the material conveying channel 9, and the guide plate 17 is arranged at the other end of the guide column 14 extending out of the fixed sleeve 15. The guide plate 17 comprises the guide inclined surface part one 19, the flat surface part 20 and the guide inclined surface part two 21 arranged in sequence along the material advancing direction, and the flat surface part 20 is a vertical surface parallel to the material advancing direction and is fixedly connected with the end of the guide column 14; the guide inclined surface part one 19 gradually inclines towards the fixed sleeve 15 in the direction opposite to the material advancing direction, and the guide inclined surface part two 21 gradually inclines towards the fixed sleeve 15 along the material advancing direction. Meanwhile, the other end of the guide column 14 extending out of the fixed sleeve 15 is also sleeved with the spring 16, and the both ends of the spring 16 abut against the guide plate 17 and the fixed sleeve 15 respectively.
[0035] On the one hand, since the fixed sleeve 15 is installed on the support frame 4 in this embodiment, it can be completely hidden inside the support frame 4, reducing its space occupation in the material conveying channel, thereby effectively ensuring the constraint effect of the support frame 4; on the other hand, this embodiment can accurately guide the conveying direction of the long profile through the guide column 14 that can flexibly extend and retract within the fixed sleeve 15 and the guide plate 17 set at the end of the guide column 14, avoiding its deviation during the conveying process. That is, when long profiles such as H-beams pass through the guide mechanism 7, the long profile will first contact the guide inclined plate. Guided by the inclined guide surface 19, the long profile gradually moves towards the center of the material conveying channel 9, thereby achieving preliminary calibration of its initial position and reducing instability caused by placement deviation. After initial guidance by the inclined guide surface 19, the long profile contacts the flat surface 20. The flat surface 20 limits the long profile, ensuring it remains vertical during conveying and does not sway or tilt, allowing it to move along the conveying direction in a stable posture. Conversely, when a backward movement of the workpiece is required, the long profile can be initially guided by the inclined guide surface 21, and then limited by the flat surface 20. Furthermore, since the spring 16 is sleeved on the guide post 14 in this embodiment, it can absorb the impact force through its own elastic deformation when the guide plate 17 is squeezed by the material, thus ensuring the stable operation of the guide plate 17. On the other hand, after the material passes through, the elastic force of the spring 16 can be used to quickly reset the guide plate 17, preparing it for the next guidance, ensuring that the long profile always maintains a stable and accurate conveying path on the conveying line, and improving conveying efficiency and processing accuracy.
