Description

Technical Field

[0001] This utility model relates to the field of duct processing technology, and more specifically, to a ventilation duct seaming machine and a ventilation duct. Background Technology

[0002] A seaming machine is a multi-functional machine mainly used for seaming metal sheets and ductwork connections. The seaming machine consists of three parts: a feeding section, a transmission section, and a forming section. The forming section mainly refers to the main machine, with the core component being the rollers. Excess material is fed between the two rollers or squeezed between them to form the seam. The feeding section is primarily manual, utilizing the gap between the rollers for feeding. The transmission section's main drive system consists of a motor, a V-belt, a reducer, open gears, and the rollers. The main machine is powered by an electromagnetic speed-regulating motor, which transmits power through a pulley, a cylindrical gear reducer, and a pin coupling to the drive shaft.

[0003] Existing seaming machines, such as the Chinese patent application number 202322387077.6, can conveniently position and stably seam the edges of the sheet metal during operation. However, they cannot easily adjust the distance between the upper and lower seaming rollers according to the thickness of the sheet metal. If the distance is too small, the sheet metal may be squeezed and deformed; if the distance is too large, the seam may not be deep enough or even. This results in poor practicality and applicability. Furthermore, after the sheet metal is processed, there is a lack of guiding devices during the removal process, which can easily cause it to deviate from the guide rail, scratch the operator, and compromise safety. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a ventilation pipe seaming machine, comprising an input component, a bending device, and an output component. The input component is located in front of the bending device and is used to flatten the sheet metal. The bending device is used to bend the sheet metal. The output component is located behind the bending device and is used to transport the processed sheet metal.

[0005] The input assembly includes an upper biting roller group, a lower biting roller group, a first motor, a second motor, two electric push rods, and two connecting frames. The upper biting roller group is vertically movable above the lower biting roller group. The distance between the upper and lower biting roller groups is used to extrude the sheet metal. The upper biting roller group includes several first biting rollers distributed at intervals. These first biting rollers are connected to each other and located at the same height. The first motor is connected to and drives the first biting rollers to rotate. The two connecting frames are respectively connected to the left and right ends of the first biting rollers. The two electric push rods are respectively connected to the two ends of the same first biting roller and drive the first biting roller to rise and fall. The lower biting roller group includes several second biting rollers distributed at intervals. These second biting rollers are connected to each other and located at the same height. The second motor is connected to and drives the second biting rollers to rotate.

[0006] Optionally, the first biting roller has connecting shafts protruding at both ends, and connecting members are fixedly sleeved on the connecting shafts. The push rod of the electric push rod is fixedly connected to the upper end of the connecting member.

[0007] Optionally, the connecting frame includes a first connecting rod and a plurality of second connecting rods, the second connecting rods being vertically fixed to the first connecting rod, and the end of the second connecting rod away from the first connecting rod being fixedly connected to the connecting shaft.

[0008] Optionally, the second connecting rod is provided with a mounting port, which is inserted into the end of the connecting shaft. The side wall of the second connecting rod is provided with a threaded hole, which is connected to the mounting port. The axis of the threaded hole is perpendicular to the axis of the mounting port. A bolt is installed in the threaded hole, which is used to abut against both sides of the connecting shaft.

[0009] Optionally, a first gear is fixedly sleeved on both the left and right ends of the first biting roller, and a second gear is fixedly sleeved on both the left and right ends of the second biting roller. A plurality of the first gears are connected to each other by a transmission chain or a transmission belt, and a plurality of the second gears are connected to each other by a transmission chain or a transmission belt.

[0010] Optionally, the output component includes a plurality of conveying rollers and a plurality of guide rollers. The plurality of conveying rollers are distributed at intervals, and the plurality of guide rollers are disposed on the left and right sides of the conveying rollers. The axis of the conveying rollers is parallel to the horizontal plane, and the axis of the guide rollers is perpendicular to the horizontal plane.

[0011] Optionally, the output component further includes baffles disposed on the left and right sides of the conveying roller, and the guide roller is mounted on the baffles.

[0012] Optionally, the output component further includes a movable plate, a slide rail, and a slide block. The guide rollers on the left or right side are mounted on the movable plate. The movable plate is provided with a clearance opening for avoiding the conveying rollers. The movable plate and the conveying rollers are slidably connected left and right. The slide rail is mounted on a workbench or the ground. The slide block is fixed to the bottom of the movable plate and slidably connected to the slide rail.

[0013] Optionally, the movable plate and the baffle are movably connected by an adjusting screw, which can drive the movable plate to move left and right when the adjusting screw is rotated in both directions.

[0014] Compared to existing technologies, the ventilation pipe seaming machine of this invention achieves efficient flattening and pre-treatment of the sheet metal through the coordinated operation of the upper and lower seaming roller groups. The electric push rod can precisely adjust the roller spacing to adapt to sheets of different thicknesses, enhancing the machine's versatility. Furthermore, in conjunction with the controller, control panel, and sensors, the control device stores the appropriate spacing for sheets of different thicknesses. The sensors scan the sheet thickness and transmit the data to the control device, which then controls the electric push rod to adaptively adjust the spacing. This eliminates the need for manual adjustment by the operator, making the machine more convenient and reducing reliance on human experience.

[0015] In addition, this utility model provides a ventilation duct, including the ventilation duct seaming machine described above.

[0016] Compared with the prior art, the ventilation duct described in this utility model has the same advantages as the ventilation duct seaming machine described above, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0025] This utility model embodiment provides a ventilation pipe sealing machine, combined with Figures 1 to 4 As shown, it includes an input component, a bending device (not shown), and an output component. The input component is located in front of the bending device and is used to flatten the sheet material. The bending device is used to bend the sheet material. The output component is located behind the bending device and is used to transport the processed sheet material.

[0026] The input assembly includes an upper biting roller group, a lower biting roller group, a first motor (not shown), a second motor (not shown), two electric push rods 1, and two connecting frames 4. The upper biting roller group is vertically movable above the lower biting roller group. The distance between the upper and lower biting roller groups is used to extrude the sheet metal. The upper biting roller group includes several first biting rollers 2 distributed at intervals. The several first biting rollers 2 are connected to each other and located at the same height. The first motor is connected to and drives the first biting rollers 2 to rotate. The two connecting frames 4 are respectively connected to the left and right ends of the several first biting rollers 2. The two electric push rods 1 are respectively connected to the two ends of the same first biting roller 2 and drive the first biting roller 2 to rise and fall. The lower biting roller group includes several second biting rollers 3 distributed at intervals. The several second biting rollers 3 are connected to each other and located at the same height. The second motor is connected to and drives the second biting rollers 3 to rotate.

[0027] like Figure 1As shown, in this embodiment, the bending device is existing technology and will not be described in detail here. The input component achieves efficient flattening and pre-processing of the sheet metal through the coordinated work of the upper and lower gripping roller groups. The electric push rod 1 can precisely adjust the roller spacing to adapt to sheets of different thicknesses, enhancing the machine's versatility. Furthermore, in conjunction with the controller, control panel, and sensors, the spacing suitable for sheets of different thicknesses is stored in the control device. The sensors scan the sheet thickness and transmit the data to the control device, which then controls the electric push rod 1 to adaptively adjust the spacing. This eliminates the need for manual adjustment by the operator, making it more convenient and reducing reliance on human experience.

[0028] like Figure 2 As shown, optionally, the first biting roller 2 has connecting shafts 21 protruding from both the left and right ends, and connecting members 5 are fixedly sleeved on the connecting shafts 21. The push rod of the electric push rod 1 is fixedly connected to the upper end of the connecting member 5.

[0029] In this embodiment, the connecting shaft 21 and the connecting piece 5 work together to provide stable support and force points, ensuring that the upper biting roller group can be stably stressed during the lifting and lowering process without affecting the rotation of the first biting roller 2.

[0030] like Figure 3 As shown, optionally, the connecting frame 4 includes a first connecting rod 41 and a plurality of second connecting rods 42, the second connecting rods 42 and the first connecting rod 41 are vertically fixed, and the end of the second connecting rod 42 away from the first connecting rod 41 is fixedly connected to the connecting shaft 21.

[0031] In this embodiment, the connecting frame 4 can be integrally formed. The first connecting rod 41 and the second connecting rod 42 cooperate to realize the synchronous linkage of multiple first biting rollers 2, which ensures the consistency of the upper biting roller group during the lifting process, enhances the stability of the equipment, and saves costs. Five first biting rollers 2 can be driven to lift and lower by one electric push rod 1.

[0032] like Figure 3 As shown, optionally, the second connecting rod 42 is provided with a mounting port 421, which is inserted into the end of the connecting shaft 21. The side wall of the second connecting rod 42 is provided with a threaded hole 422, which connects to the mounting port 421. The axis of the threaded hole 422 is perpendicular to the axis of the mounting port 421. A bolt is installed in the threaded hole 422, and the bolt is used to abut against both sides of the connecting shaft 21. In this embodiment, the mating design of the mounting port 421 and the connecting shaft 21 enables quick installation, and the bolt locking mechanism ensures a secure connection of the transmission components.

[0033] like Figure 1As shown, optionally, the first biting roller 2 is fixedly fitted with a first gear 6 at both ends, and the second biting roller 3 is fixedly fitted with a second gear 7 at both ends. A plurality of first gears 6 are connected to each other by a transmission chain or transmission belt, and a plurality of second gears 7 are connected to each other by a transmission chain or transmission belt.

[0034] In this embodiment, the gear transmission system achieves synchronous rotation of multiple bite rollers via chains or belts, ensuring uniform distribution of driving force. A first motor drives multiple first bite rollers 2 to rotate, and a second motor drives multiple second bite rollers 3 to rotate, avoiding the high cost of using one motor per bite roller.

[0035] like Figure 4 As shown, optionally, the output component includes a plurality of conveying rollers 8 and a plurality of guide rollers 9. The plurality of conveying rollers 8 are distributed at intervals, and the plurality of guide rollers 9 are disposed on the left and right sides of the conveying rollers. The wheel axis of the conveying rollers 8 is parallel to the horizontal plane, and the wheel axis of the guide rollers 9 is perpendicular to the horizontal plane.

[0036] In this embodiment, the output component, through the combination of conveying roller 8 and guide roller 9, achieves stable transportation and guidance of the processed sheet material, preventing the sheet material from shifting during the output process and scratching the operator, thereby improving stability and safety.

[0037] like Figure 4 As shown, optionally, the output component further includes a baffle 10, which is disposed on the left and right sides of the conveying roller 8, and the guide roller 9 is mounted on the baffle 10.

[0038] In this embodiment, the baffle 10 serves as the mounting base for the guide roller 9, providing additional lateral support and protection, enhancing the stability of the output process, further preventing the plate from deviating from the predetermined path, reducing the need for manual correction, and improving safety.

[0039] like Figure 4 As shown, optionally, the output component further includes a movable plate 11, a slide rail 12, and a slide block 13. The guide roller 9 on the left or right side is mounted on the movable plate 11. The movable plate 11 is provided with a clearance opening for avoiding the conveying roller 8. The movable plate 11 and the conveying roller 8 are slidably connected left and right. The slide rail 12 is mounted on a workbench or the ground. The slide block 13 is fixed to the bottom of the movable plate 11 and slidably connected to the slide rail 12.

[0040] In this embodiment, the design of the movable plate 11, the slide rail 12 and the slide block 13 allows the position of the guide roller 9 to be flexibly adjusted to adapt to plates of different widths, thus improving versatility and adaptability.

[0041] like Figure 4 As shown, optionally, the movable plate 11 and the baffle 10 are movably connected by an adjusting screw 14. When the adjusting screw 14 is rotated in both directions, it can drive the movable plate 11 to move left and right. In this embodiment, the adjusting screw 14 can be driven to rotate manually or by a motor, which is simple to operate. The structure and principle of the adjusting screw rotating to drive the movement are existing technologies and will not be described in detail here.
