Description

Technical Field

[0001] The utility model relates to the field of biting machines, in particular to a biting machine for making air ducts. Background Art

[0002] Air duct is a piping system used to transport air, commonly found in various places such as buildings, industrial facilities and vehicles. They are usually used in heating, ventilation, air conditioning and exhaust systems to transport air from one place to another. Air duct is an indispensable part of modern buildings and industrial facilities, providing the necessary air circulation and regulation functions for the indoor environment. In the process of air duct processing and manufacturing, in order to ensure the firmness, sealing and aesthetics of the air duct connection, it is necessary to use a biting machine to process the edge biting of the air duct.

[0003] However, there are some problems in the actual working process of the existing air duct manufacturing bite machines. For example, the ventilation duct preform bite processing device with publication number CN202023227988.5 can conveniently position and stably bite the edge of the steel plate during operation, but it cannot automatically load the raw materials of the steel plate for air duct manufacturing in the actual working process. Therefore, the staff still needs to lift the steel plates one by one and place them on the workbench, which has low work efficiency and high labor intensity; and in the actual working process, it cannot conveniently adjust the distance between the upper and lower bite wheel groups according to the thickness of the steel plate raw material, and its practicality and applicability are poor. If the distance is set improperly, it may cause excessive or insufficient bite processing. If the distance is too small, it may cause the plate to be squeezed and deformed. If the distance is too large, the bite may not be deep enough or uneven. Therefore, we have made improvements to this and proposed an air duct manufacturing bite machine. Utility Model Content

By utilizing the movement of the transmission belt 11 and cooperating with the lever 12, the sheet body 5 at the lowest end of the inner side of the loading frame 2 can be automatically loaded, thereby ensuring the convenience of subsequent biting work of the sheet body 5. At the same time, by utilizing the continuous movement of the transmission belt 11 and cooperating with the lever 12, the loading work of the sheet body 5 one by one can be automatically completed.

[0042] like Figure 3-Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a lower pressure roller 15 is rotatably connected to the fixed frame 14, a second threaded rod 16 is threadedly connected to the top of the fixed frame 14, the bottom end of the second threaded rod 16 is rotatably connected to a limiting block 17, the limiting block 17 is slidably connected in the fixed frame 14, a second servo motor 18 is welded and fixed to the limiting block 17, an upper pressure roller 19 is welded and fixed to the output shaft of the second servo motor 18, the shape and size of the lower pressure roller 15 are the same as those of the upper pressure roller 19, and the top end surface of the lower pressure roller 15, the top end surface of the support plate 13, the lower bite roller 26 and the top end surface of the inner bottom end surface of the loading frame 2 are located on the same horizontal plane.

[0043] like Figure 4 and Fig. 9As shown, as a preferred embodiment, on the basis of the above method, further, the first rotating shaft 23 is equidistantly distributed on the first mounting frame 20, the first rotating shaft 23 corresponds to the first sprocket 24 and the lower bite roller 26 respectively, the output shaft of the third servo motor 22 is welded to the first rotating shaft 23 at the outermost side, the second rotating shaft 33 is equidistantly distributed on the second mounting frame 30, the second rotating shaft 33 corresponds to the second sprocket 34 and the upper bite roller 36 respectively, the output shaft of the fourth servo motor 32 is welded to the second rotating shaft 33 at the outermost side, the upper bite roller 36 is welded to the lower bite roller 36 The mouth rollers 26 correspond one to one, and by rotating the thread of the second threaded rod 16, the upper pressure roller 19 can be driven to move upward or downward through the limit block 17 until the distance between the upper pressure roller 19 and the lower pressure roller 15 is equal to the thickness of the plate body 5, and then the upper pressure roller 19 is driven by the second servo motor 18, and the lower pressure roller 15 can automatically and stably smooth the side of the plate body 5 that is fed by the lever 12, thereby eliminating the unevenness, defects and deformation on the side of the plate body 5, ensuring that the plate body 5 remains flat during the biting process, thereby improving the processing accuracy and quality.

[0044] like Fig. 9 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the reinforcing plate 29 and the scale 27 are symmetrically distributed on both sides of the second mounting frame 30, the reinforcing plate 29 corresponds to the third threaded rod 28 one by one, and the bottom end surface of the scale 27 is located on the same horizontal plane as the horizontal center axis of the first rotating shaft 23. By utilizing the synchronous rotation of the third threaded rods 28 on both sides, the second mounting frame 30 can be driven to move upward or downward through the reinforcing plate 29. Combined with the scale 27, the distance between the lower bite roller 26 and the upper bite roller 36 can be adjusted conveniently and accurately, and then the distance between the lower bite roller 26 and the upper bite roller 36 can be adjusted according to the thickness of the plate body 5, thereby avoiding the problem of excessive or insufficient bite processing in the process of duct manufacturing, improving the processing accuracy and efficiency, and reducing the scrap rate caused by poor processing.

[0045] Specifically, when the air duct making bite machine is in use: first, the staff can place the plate body 5 to be used inside the loading frame 2, and then the staff can rotate the first threaded rod 3 at the rear. At this time, under the action of the thread rotation of the first threaded rod 3, the adjusting plate 4 connected to the end rotation can be driven to move forward or backward until the adjusting plate 4 at the rear moves to a suitable position, so that the plate body 5 is in close contact with the adjusting plate 4 at the rear and is in a suitable loading position. Then the staff can rotate the second threaded rod 16 on the fixed frame 14. At this time, under the action of the thread rotation of the second threaded rod 16, the limit block 17 can be pushed to move upward or downward, thereby driving the upper pressure roller 19 to move upward or downward until the distance between the upper pressure roller 19 and the lower pressure roller 15 is The thickness of the plate body 5 is equal to that of the plate body 5. Then, the staff member rotates the third threaded rods 28 on both sides at the same time. At this time, under the simultaneous rotation of the third threaded rods 28 on both sides, the reinforcing plate 29 connected by thread can drive the second installation frame 30 to move upward or downward. In combination with the scale 27, the distance between the lower bite roller 26 and the upper bite roller 36 can be conveniently and accurately adjusted, and then the distance between the lower bite roller 26 and the upper bite roller 36 can be adjusted according to the thickness of the plate body 5. The height adjustment of the second installation frame 30 can be completed by rotating the third threaded rods 28 on both sides at the same time, so as to avoid the staff member accidentally touching the third threaded rod 28 on one side, resulting in a change in the distance between the lower bite roller 26 and the upper bite roller 36, which affects the stability and accuracy of the subsequent bite processing work;

[0046] Then the staff can rotate the first threaded rod 3 in the front. At this time, the adjustment plate 4 connected to the end rotation can be driven to move backward under the action of the thread rotation of the first threaded rod 3. At this time, under the action of the movement of the adjustment plate 4, each plate body 5 can be pushed to be in close contact with the rear adjustment plate 4. At this time, under the joint action of the front and rear adjustment plates 4, the plate bodies 5 of different sizes can be conveniently and stably limited. At the same time, the plate body 5 can be limited to a suitable feeding position to ensure the stability of the subsequent bite of the plate body 5.

[0047] After the plate body 5 is limited, the staff can control to start the first servo motor 9, the second servo motor 18, the third servo motor 22 and the fourth servo motor 32. At this time, under the driving action of the first servo motor 9, the synchronous wheel 10 on one side can be driven to move automatically, and the synchronous wheel 10 on the other side can drive the transmission belt 11 to move at a uniform speed. At this time, under the movement of the transmission belt 11, the lever 12 can be driven to move synchronously, and under the movement of the lever 12, the feeding groove 6 and the through groove 8 at the bottom of the feeding frame 2 can be passed, and during the movement of the lever 12, the lever 12 can be driven to move. The sheet body 5 at the lowest end inside the loading frame 2 moves, and at this time, the sheet body 5 at the lowest end inside the loading frame 2 can move away from the loading frame 2 through the loading groove 6. At the same time, the sheet body 5 of the second-to-last layer can be stably located in the loading frame 2 under the limiting action of the rubber plate 7, until the sheet body 5 at the lowest end inside the loading frame 2 moves away from the loading frame 2. At this time, under the action of gravity, the sheet body 5 of the second-to-last layer can stably fall to the bottom end surface inside the loading frame 2, waiting for the next toggle of the lever 12, and so on, and the loading work of the sheet bodies 5 one by one can be automatically completed;

[0048] When the sheet body 5 at the lowest end of the feeding frame 2 moves away from the feeding frame 2, it can stably move to the lower pressure roller 15. At this time, under the driving action of the second servo motor 18, the upper pressure roller 19 can be driven to rotate clockwise. At this time, under the clockwise rotation of the upper pressure roller 19, in cooperation with the lower pressure roller 15, the side of the sheet body 5 that is fed by the lever 12 can be automatically and stably leveled, thereby eliminating the unevenness, defects and deformation on the side of the sheet body 5, ensuring that the sheet body 5 remains flat during the bite process. The sheet body 5 after leveling can be stably moved to the lower bite roller 26 under the supporting action of the support plate 13. At this time, under the driving action of the third servo motor 22 on the first support plate 21, the first rotating shaft 23 on the outermost side can be driven to rotate, thereby driving the first sprocket 24 on the outermost side to rotate stably. At this time, at the outermost side, the first sprocket 24 on the outermost side can be driven to rotate stably. Under the rotation of a sprocket 24, in cooperation with the first chain 25, each first sprocket 24 can be driven to rotate counterclockwise synchronously, thereby driving the corresponding lower bite roller 26 to rotate counterclockwise synchronously. At the same time, under the driving action of the fourth servo motor 32 on the second support plate 31, the second rotating shaft 33 on the outermost side can be driven to rotate, thereby driving the second sprocket 34 on the outermost side to rotate stably. At this time, under the rotation of the second sprocket 34 on the outermost side, in cooperation with the second chain 35, each upper bite roller 36 can be driven to rotate clockwise synchronously. At this time, under the joint rotation of each lower bite roller 26 and each upper bite roller 36, the plate body 5 can be subjected to bite processing. After the bite processing, the plate body 5 can be unloaded from the left side, and after the bite processing of the plate body 5, the subsequent air duct production processing can be carried out.

[0049] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods.
